Synchronous Motor

Chapter (11) Synchronous Motors Introduction It may be recalled that a d. c. generator can be run as a d. c. motor. In like manner, an alternator may operate as a motor by connecting its armature winding to a 3-phase supply. It is then called a synchronous motor. As the name implies, a synchronous motor runs at synchronous speed (Ns = 120f/P) i. e. , in synchronism with the revolving field produced by the 3-phase supply. The speed of rotation is, therefore, tied to the frequency of the source.Since the frequency is fixed, the motor speed stays constant irrespective of the load or voltage of 3phase supply. However, synchronous motors are not used so much because they run at constant speed (i. e. , synchronous speed) but because they possess other unique electrical properties. In this chapter, we shall discuss the working and characteristics of synchronous motors. 11. 1 Construction A synchronous motor is a machine that operates at synchronous speed and converts electrical energy into mechanical energy. It is fundamentally an alternator operated as a motor.Like an alternator, a synchronous motor has the following two parts: (i) a stator which houses 3-phase armature winding in the slots of the stator core and receives power from a 3-phase supply [See (Fig. (11. 1)]. (ii) a rotor that has a set of salient poles excited by direct current to form alternate N and S poles. The exciting coils are connected in series to two slip rings and direct current is fed into the winding from an external exciter mounted on the rotor shaft. The stator is wound for the same number of poles as the rotor poles.As in the case of an induction motor, the number of poles determines the synchronous speed of the motor: Fig. (11. 1) 293 Synchronous speed, N s = where 120f P f = frequency of supply in Hz P = number of poles An important drawback of a synchronous motor is that it is not self-starting and auxiliary means have to be used for starting it. 11. 2 Some Facts about Synchronous Motor Some salient features of a synchronous motor are: (i) A synchronous motor runs at synchronous speed or not at all. Its speed is constant (synchronous speed) at all loads. The only way to change its speed is to alter the supply frequency (Ns = 120 f/P). ii) The outstanding characteristic of a synchronous motor is that it can be made to operate over a wide range of power factors (lagging, unity or leading) by adjustment of its field excitation. Therefore, a synchronous motor can be made to carry the mechanical load at constant speed and at the same time improve the power factor of the system. (iii) Synchronous motors are generally of the salient pole type. (iv) A synchronous motor is not self-starting and an auxiliary means has to be used for starting it. We use either induction motor principle or a separate starting motor for this purpose.If the latter method is used, the machine must be run up to synchronous speed and synchronized as an alternator. 11. 3 Operating Principle The fact that a synchronous motor has no starting torque can be easily explained. (i) Consider a 3-phase synchronous motor having two rotor poles NR and SR. Then the stator will also be wound for two poles NS and SS. The motor has direct voltage applied to the rotor winding and a 3-phase voltage applied to the stator winding. The stator winding produces a rotating field which revolves round the stator at synchronous speed Ns(= 120 f/P).The direct (or zero frequency) current sets up a two-pole field which is stationary so long as the rotor is not turning. Thus, we have a situation in which there exists a pair of revolving armature poles (i. e. , NS ? SS) and a pair of stationary rotor poles (i. e. , NR ? SR). (ii) Suppose at any instant, the stator poles are at positions A and B as shown in Fig. (11. 2 (i)). It is clear that poles NS and NR repel each other and so do the poles SS and SR. Therefore, the rotor tends to move in the anticlockwise direction. After a period of half-cycle (or ? = 1 /100 second), the polarities of the stator poles are reversed but the polarities of the rotor poles remain the same as shown in Fig. (11. 2 (ii)). Now SS and NR attract 294 each other and so do NS and SR. Therefore, the rotor tends to move in the clockwise direction. Since the stator poles change their polarities rapidly, they tend to pull the rotor first in one direction and then after a period of half-cycle in the other. Due to high inertia of the rotor, the motor fails to start. Fig. (10. 2) Hence, a synchronous motor has no self-starting torque i. e. , a synchronous motor cannot start by itself.How to get continuous unidirectional torque? If the rotor poles are rotated by some external means at such a speed that they interchange their positions along with the stator poles, then the rotor will experience a continuous unidirectional torque. This can be understood from the following discussion: (i) Suppose the stator field is rotating in the clockwise direction and the rotor is als o rotated clockwise by some external means at such a speed that the rotor poles interchange their positions along with the stator poles. (ii) Suppose at any instant the stator and rotor poles are in the position shown in Fig. 11. 3 (i)). It is clear that torque on the rotor will be clockwise. After a period of half-cycle, the stator poles reverse their polarities and at the same time rotor poles also interchange their positions as shown in Fig. (11. 3 (ii)). The result is that again the torque on the rotor is clockwise. Hence a continuous unidirectional torque acts on the rotor and moves it in the clockwise direction. Under this condition, poles on the rotor always face poles of opposite polarity on the stator and a strong magnetic attraction is set up between them.This mutual attraction locks the rotor and stator together and the rotor is virtually pulled into step with the speed of revolving flux (i. e. , synchronous speed). (iii) If now the external prime mover driving the rotor is removed, the rotor will continue to rotate at synchronous speed in the clockwise direction because the rotor poles are magnetically locked up with the stator poles. It is due to 295 this magnetic interlocking between stator and rotor poles that a synchronous motor runs at the speed of revolving flux i. e. , synchronous speed. Fig. (11. 3) 11. Making Synchronous Motor Self-Starting A synchronous motor cannot start by itself. In order to make the motor self-starting, a squirrel cage winding (also called damper winding) is provided on the rotor. The damper winding consists of copper bars embedded in the pole faces of the salient poles of the rotor as shown in Fig. (11. 4). The bars are short-circuited at the ends to form in effect a partial Fig. (11. 4) squirrel cage winding. The damper winding serves to start the motor. (i) To start with, 3-phase supply is given to the stator winding while the rotor field winding is left unenergized.The rotating stator field induces currents in the damper or squirrel cage winding and the motor starts as an induction motor. (ii) As the motor approaches the synchronous speed, the rotor is excited with direct current. Now the resulting poles on the rotor face poles of opposite polarity on the stator and a strong magnetic attraction is set up between them. The rotor poles lock in with the poles of rotating flux. Consequently, the rotor revolves at the same speed as the stator field i. e. , at synchronous speed. iii) Because the bars of squirrel cage portion of the rotor now rotate at the same speed as the rotating stator field, these bars do not cut any flux and, therefore, have no induced currents in them. Hence squirrel cage portion of the rotor is, in effect, removed from the operation of the motor. 296 It may be emphasized here that due to magnetic interlocking between the stator and rotor poles, a synchronous motor can only run at synchronous speed. At any other speed, this magnetic interlocking (i. e. , rotor poles facing o pposite polarity stator poles) ceases and the average torque becomes zero.Consequently, the motor comes to a halt with a severe disturbance on the line. Note: It is important to excite the rotor with direct current at the right moment. For example, if the d. c. excitation is applied when N-pole of the stator faces Npole of the rotor, the resulting magnetic repulsion will produce a violent mechanical shock. The motor will immediately slow down and the circuit breakers will trip. In practice, starters for synchronous motors arc designed to detect the precise moment when excitation should be applied. 11. 5 Equivalent Circuit Unlike the induction motor, the synchronous motor is connected to two electrical systems; a d. . source at the rotor terminals and an a. c. system at the stator terminals. 1. Under normal conditions of synchronous motor operation, no voltage is induced in the rotor by the stator field because the rotor winding is rotating at the same speed as the stator field. Only the impressed direct current is present in the rotor winding and ohmic resistance of this winding is the only opposition to it as shown in Fig. (11. 5 (i)). 2. In the stator winding, two effects are to be considered, the effect of stator field on the stator winding and the effect of the rotor field cutting the stator conductors at synchronous speed.Fig. (11. 5) (i) The effect of stator field on the stator (or armature) conductors is accounted for by including an inductive reactance in the armature winding. This is called synchronous reactance Xs. A resistance Ra must be considered to be in series with this reactance to account for the copper losses in the stator or armature winding as shown in Fig. (11. 5 (i)). This 297 resistance combines with synchronous reactance and gives the synchronous impedance of the machine. (ii) The second effect is that a voltage is generated in the stator winding by the synchronously-revolving field of the rotor as shown in Fig. 11. 5 (i)). This generat ed e. m. f. EB is known as back e. m. f. and opposes the stator voltage V. The magnitude of Eb depends upon rotor speed and rotor flux ? per pole. Since rotor speed is constant; the value of Eb depends upon the rotor flux per pole i. e. exciting rotor current If. Fig. (11. 5 (i)) shows the schematic diagram for one phase of a star-connected synchronous motor while Fig. (11. 5 (ii)) shows its equivalent circuit. Referring to the equivalent circuit in Fig. (11. 5 (ii)). Net voltage/phase in stator winding is Er = V ? Eb Armature current/phase, I a = where 2 Zs = R 2 + X s a hasor difference Er Zs This equivalent circuit helps considerably in understanding the operation of a synchronous motor. A synchronous motor is said to be normally excited if the field excitation is such that Eb = V. If the field excitation is such that Eb < V, the motor is said to be under-excited. The motor is said to be over-excited if the field excitation is such that Eb > V. As we shall see, for both normal an d under excitation, the motor has lagging power factor. However, for over-excitation, the motor has leading power factor.Note: In a synchronous motor, the value of Xs is 10 to 100 times greater than Ra. Consequently, we can neglect Ra unless we are interested in efficiency or heating effects. 11. 6 Motor on Load In d. c. motors and induction motors, an addition of load causes the motor speed to decrease. The decrease in speed reduces the counter e. m. f. enough so that additional current is drawn from the source to carry the increased load at a reduced speed. This action cannot take place in a synchronous motor because it runs at a constant speed (i. e. , synchronous speed) at all loads.What happens when we apply mechanical load to a synchronous motor? The rotor poles fall slightly behind the stator poles while continuing to run at 298 synchronous speed. The angular displacement between stator and rotor poles (called torque angle ? ) causes the phase of back e. m. f. Eb to change w. r. t. supply voltage V. This increases the net e. m. f. Er in the stator winding. Consequently, stator current Ia ( = Er/Zs) increases to carry the load. Fig. (11. 6) The following points may be noted in synchronous motor operation: (i) A synchronous motor runs at synchronous speed at all loads.It meets the increased load not by a decrease in speed but by the relative shift between stator and rotor poles i. e. , by the adjustment of torque angle ?. (ii) If the load on the motor increases, the torque angle a also increases (i. e. , rotor poles lag behind the stator poles by a greater angle) but the motor continues to run at synchronous speed. The increase in torque angle ? causes a greater phase shift of back e. m. f. Eb w. r. t. supply voltage V. This increases the net voltage Er in the stator winding. Consequently, armature current Ia (= Er/Zs) increases to meet the load demand. iii) If the load on the motor decreases, the torque angle ? also decreases. This causes a smaller phase shift of Eb w. r. t. V. Consequently, the net voltage Er in the stator winding decreases and so does the armature current Ia (= Er/Zs). 11. 7 Pull-Out Torque There is a limit to the mechanical load that can be applied to a synchronous motor. As the load increases, the torque angle ? also increases so that a stage is reached when the rotor is pulled out of synchronism and the motor comes to a standstill. This load torque at which the motor pulls out of synchronism is called pull—out or breakdown torque.Its value varies from 1. 5 to 3. 5 times the full— load torque. When a synchronous motor pulls out of synchronism, there is a major disturbance on the line and the circuit breakers immediately trip. This protects the motor because both squirrel cage and stator winding heat up rapidly when the machine ceases to run at synchronous speed. 299 11. 8 Motor Phasor Diagram Consider an under-excited ^tar-connected synchronous motor (Eb < V) supplied with fixed excitation i. e. , back e. m. f. Eb is constantLet V = supply voltage/phase Eb = back e. m. f. /phase Zs = synchronous impedance/phase (i) Motor on no loadWhen the motor is on no load, the torque angle ? is small as shown in Fig. (11. 7 (i)). Consequently, back e. m. f. Eb lags behind the supply voltage V by a small angle ? as shown in the phasor diagram in Fig. (11. 7 (iii)). The net voltage/phase in the stator winding, is Er. Armature current/phase, Ia = Er/Zs The armature current Ia lags behind Er by ? = tan-1 Xs/Ra. Since Xs >> Ra, Ia lags Er by nearly 90Â °. The phase angle between V and Ia is ? so that motor power factor is cos ?. Input power/phase = V Ia cos ? Fig. (11. 7) Thus at no load, the motor takes a small power VIa cos ? phase from the supply to meet the no-load losses while it continues to run at synchronous speed. (ii) Motor on load When load is applied to the motor, the torque angle a increases as shown in Fig. (11. 8 (i)). This causes Eb (its magnitude is constant as excitation is fixed) to lag behind V by a greater angle as shown in the phasor diagram in Fig. (11. 8 (ii)). The net voltage/phase Er in the stator winding increases. Consequently, the motor draws more armature current Ia (=Er/Zs) to meet the applied load. Again Ia lags Er by about 90Â ° since Xs >> Ra. The power factor of the motor is cos ?. 300 Input power/phase, Pi = V Ia cos ?Mechanical power developed by motor/phase Pm = Eb ? Ia ? cosine of angle between Eb and Ia = Eb Ia cos(? ? ? ) Fig. (11. 8) 11. 9 Effect of Changing Field Excitation at Constant Load In a d. c. motor, the armature current Ia is determined by dividing the difference between V and Eb by the armature resistance Ra. Similarly, in a synchronous motor, the stator current (Ia) is determined by dividing voltage-phasor resultant (Er) between V and Eb by the synchronous impedance Zs. One of the most important features of a synchronous motor is that by changing the field excitation, it can be made to operate from lagging to eadin g power factor. Consider a synchronous motor having a fixed supply voltage and driving a constant mechanical load. Since the mechanical load as well as the speed is constant, the power input to the motor (=3 VIa cos ? ) is also constant. This means that the in-phase component Ia cos ? drawn from the supply will remain constant. If the field excitation is changed, back e. m. f Eb also changes. This results in the change of phase position of Ia w. r. t. V and hence the power factor cos ? of the motor changes. Fig. (11. 9) shows the phasor diagram of the synchronous motor for different values of field excitation.Note that extremities of current phasor Ia lie on the straight line AB. (i) Under excitation The motor is said to be under-excited if the field excitation is such that Eb < V. Under such conditions, the current Ia lags behind V so that motor power factor is lagging as shown in Fig. (11. 9 (i)). This can be easily explained. Since Eb < V, the net voltage Er is decreased and turn s clockwise. As angle ? (= 90Â °) between Er and Ia is constant, therefore, phasor Ia also turns clockwise i. e. , current Ia lags behind the supply voltage. Consequently, the motor has a lagging power factor. 301 ii) Normal excitation The motor is said to be normally excited if the field excitation is such that Eb = V. This is shown in Fig. (11. 9 (ii)). Note that the effect of increasing excitation (i. e. , increasing Eb) is to turn the phasor Er and hence Ia in the anti-clockwise direction i. e. , Ia phasor has come closer to phasor V. Therefore, p. f. increases though still lagging. Since input power (=3 V Ia cos ? ) is unchanged, the stator current Ia must decrease with increase in p. f. Fig. (11. 9) Suppose the field excitation is increased until the current Ia is in phase with the applied voltage V, making the p. . of the synchronous motor unity [See Fig. (11. 9 (iii))]. For a given load, at unity p. f. the resultant Er and, therefore, Ia are minimum. (iii) Over excitation T he motor is said to be overexcited if the field excitation is such that Eb > V. Under-such conditions, current Ia leads V and the motor power factor is leading as shown in Fig. (11. 9 (iv)). Note that Er and hence Ia further turn anti-clockwise from the normal excitation position. Consequently, Ia leads V. From the above discussion, it is concluded that if the synchronous motor is under-excited, it has a lagging power factor.As the excitation is increased, the power factor improves till it becomes unity at normal excitation. Under such conditions, the current drawn from the supply is minimum. If the excitation is further increased (i. e. , over excitation), the motor power factor becomes leading. Note. The armature current (Ia) is minimum at unity p. f and increases as the power factor becomes poor, either leading or lagging. 302 11. 10 Phasor Diagrams With Different Excitations Fig. (11. 10) shows the phasor diagrams for different field excitations at constant load. Fig. (11. 10 (i )) shows the phasor diagram for normal excitation (Eb = V), whereas Fig. 11. 10 (ii)) shows the phasor diagram for under-excitation. In both cases, the motor has lagging power factor. Fig. (11. 10 (iii)) shows the phasor diagram when field excitation is adjusted for unity p. f. operation. Under this condition, the resultant voltage Er and, therefore, the stator current Ia are minimum. When the motor is overexcited, it has leading power factor as shown in Fig. (11. 10 (iv)). The following points may be remembered: (i) For a given load, the power factor is governed by the field excitation; a weak field produces the lagging armature current and a strong field produces a leading armature current. ii) The armature current (Ia) is minimum at unity p. f and increases as the p. f. becomes less either leading or lagging. Fig. (11. 10) 11. 11 Power Relations Consider an under-excited star-connected synchronous motor driving a mechanical load. Fig. (11. 11 (i)) shows the equivalent circuit for one phase, while Fig. (11. 11 (ii)) shows the phasor diagram. Fig. (11. 11) 303 (i) (ii) Input power/phase, Pi = V Ia cos ? Mechanical power developed by the motor/phase, Pm = Eb ? Ia ? cosine of angle between Eb and Ia = Eb Ia cos(? ? ? ) Armature Cu loss/phase = I 2 R a = Pi ?

Fig. (11. 12) 11. 12 Motor Torque Gross torque, Tg = 9. 55 where Pm N-m Ns Pm = Gross motor output in watts = Eb Ia cos(? ? ? ) Ns = Synchronous speed in r. p. m. Shaft torque, Tsh = 9. 55 Pout N-m Ns It may be seen that torque is directly proportional to the mechanical power because rotor speed (i. e. , Ns) is fixed. 11. 13 Mechanical Power Developed By Motor (Armature resistance neglected) Fig. (11. 13) shows the phasor diagram of an under-excited synchronous motor driving a mechanical load.Since armature resistance Ra is assumed zero. tan? = Xs/Ra = ? an d hence ? = 90Â °. Input power/phase = V Ia cos ? Fig. (11. 13) 304 Since Ra is assumed zero, stator Cu loss (I 2 R a ) will be zero. Hence input power a is equal to the mechanical power Pm developed by the motor. Mech. power developed/ phase, Pm = V Ia cos ? Referring to the phasor diagram in Fig. (11. 13), (i) AB = E r cos ? = I a X s cos ? Also AB = E b sin ? ? E b sin ? = I a X s cos ? or I a cos ? = E b sin ? Xs Substituting the value of Ia cos ? in exp. (i) above, Pm = = V Eb Xs VEb Xs per phase for 3-phaseIt is clear from the above relation that mechanical power increases with torque angle (in electrical degrees) and its maximum value is reached when ? = 90Â ° (electrical). Pmax = V Eb Xs per phase Under this condition, the poles of the rotor will be mid-way between N and S poles of the stator. 11. 14 Power Factor of Synchronous Motors In an induction motor, only one winding (i. e. , stator winding) produces the necessary flux in the machine. The stator winding must draw re active power from the supply to set up the flux. Consequently, induction motor must operate at lagging power factor.But in a synchronous motor, there are two possible sources of excitation; alternating current in the stator or direct current in the rotor. The required flux may be produced either by stator or rotor or both. (i) If the rotor exciting current is of such magnitude that it produces all the required flux, then no magnetizing current or reactive power is needed in the stator. As a result, the motor will operate at unity power factor. 305 (ii) If the rotor exciting current is less (i. e. , motor is under-excited), the deficit in flux is made up by the stator. Consequently, the motor draws reactive power to provide for the remaining flux.Hence motor will operate at a lagging power factor. (iii) If the rotor exciting current is greater (i. e. , motor is over-excited), the excess flux must be counterbalanced in the stator. Now the stator, instead of absorbing reactive power, a ctually delivers reactive power to the 3-phase line. The motor then behaves like a source of reactive power, as if it were a capacitor. In other words, the motor operates at a leading power factor. To sum up, a synchronous motor absorbs reactive power when it is underexcited and delivers reactive power to source when it is over-excited. 11. 15 Synchronous CondenserA synchronous motor takes a leading current when over-excited and, therefore, behaves as a capacitor. An over-excited synchronous motor running on no-load in known as synchronous condenser. When such a machine is connected in parallel with induction motors or other devices that operate at low lagging power factor, the leading kVAR supplied by the synchronous condenser partly neutralizes the lagging reactive kVAR of the loads. Consequently, the power factor of the system is improved. Fig. (11. 14) shows the power factor improvement by synchronous condenser method. The 3 ? ? load takes current IL at low lagging power factor cos ?L. The synchronous condenser takes a current Im which leads the voltage by an angle ? m. The resultant current I is the vector sum of Im and IL and lags behind the voltage by an angle ?. It is clear that ? is less than ? L so that cos ? is greater than cos ? L. Thus the power factor is increased from cos ? L to cos ?. Synchronous condensers are generally used at major bulk supply substations for power factor improvement. Advantages (i) By varying the field excitation, the magnitude of current drawn by the motor can be changed by any amount. This helps in achieving stepless control of power factor. ii) The motor windings have high thermal stability to short circuit currents. (iii) The faults can be removed easily. 306 Fig. (11. 14) Disadvantages (i) (ii) (iii) (iv) There are considerable losses in the motor. The maintenance cost is high. It produces noise. Except in sizes above 500 RVA, the cost is greater than that of static capacitors of the same rating. (v) As a synchronous m otor has no self-starting torque, then-fore, an auxiliary equipment has to be provided for this purpose. 11. 16 Applications of Synchronous Motors (i) Synchronous motors are particularly attractive for low speeds (< 300 r. . m. ) because the power factor can always be adjusted to unity and efficiency is high. (ii) Overexcited synchronous motors can be used to improve the power factor of a plant while carrying their rated loads. (iii) They are used to improve the voltage regulation of transmission lines. (iv) High-power electronic converters generating very low frequencies enable us to run synchronous motors at ultra-low speeds. Thus huge motors in the 10 MW range drive crushers, rotary kilns and variable-speed ball mills. 307 11. 17 Comparison of Synchronous and Induction Motors S. Particular No. 1.Speed 2. 3. 4.

Pategonia’s Expansion Strategy Essay

1. Patagonia’s Current Strategy: Key Processes and Customer Perception In the context of our business model our number one key process is our Rules and Norms (a complete breakdown of Patagonia’s current business model and a to-be-proposed business model are available for review in Exhibit I). This ethos that started with the founding of Chouinard Equipment continued through the creation of Lost Arrow and indeed Patagonia. Our self-proclaimed â€Å"dirtbag† culture has resulted in some unorthodox business practices over the years. We pride ourselves on our efforts to reduce the social and environmental impact of the lifetime of the goods and services we produce. This is something that our competitors recognize but do not focus efforts on; for us it is of the utmost importance. I took this liberty to draft a Customer Value Proposition (CVP) for our current model: â€Å"We provide high quality, durable outdoor athletic clothing and accessories that are produced with a high standard for environmental and social impact. We make the products that we want to use.† To extrapolate on the latter portion of our CVP, we expect our employees to not only share in the environmental and social consciousness that Mr Chouinard has weaved into the culture of Patagonia but we expect employees to be users of our products as well. This gives us an incredible insight into the functionality and durability of our products. This is exemplified in our generous sabbaticals and midday surfing breaks at our corporate headquarters. Additional insight in this regard is provided by our investment in brand ambassadors, who also provide us with the core of our visual marketing in our catalogs, our website, and social media. In order of volume we move our products through three main channels: wholesale, retail, catalog/internet. In order of profitability the channels are arranged as such retail, catalog/internet[1], and wholesale. There is an additional product repair arm of Patagonia’s structure that at the moment is not profitable. Our commitment to the ethical fiber that binds the core of what Patagonia as a brand stands for results in a product that comes at a premium price, however we believe that the money you spend on Patagonia products is a contribution to our commitment for care when it comes to the environments and social spheres within which we operate. So far we have seen success as shown below. 2. Financial Review of Current Business Model The competition analysis in Exhibit III outlines our industries averages for financial health. It would seem that our â€Å"dirtbag† approach to business has boded well for us over the last ten years. While our total market share (annual sales) is far below the industry average over all the company is making money. Our gross profit margin is over 6% higher than the industry average and our pre-tax profit margin is right in line with the industry average. While Patagonia’s ROE and ROA are below the industry average it is not my much and our debt to equity ratio is far below the industry average. So while we holds more equity and assets on hand than our competitors we has enough liquid cash flow to finance operations without having to incur much debt. Our 12 month revenue growth is trending along with the industry however our 12 month net growth income is nearly 13% higher than our competitors. Thus while we are experiencing growth that is on par with the industry we are experiencing a downward turn in our operating and/or material costs. It should be noted that the information here is of companies who compete in our industry but not exclusively. Columbia is the competitor that competes most directly with our niche in the industry and on every account except for debt/equity our numbers are favorable and even in the case of debt/equity the difference is negligible. The standards for philanthropy and an ethical purview for production and material sourcing at Patagonia are much higher than the industry average. We donate 1% of gross sales to environmental initiatives and causes, and our COGS are higher than competitors as a result of our ethical stance. However, once again (as shown in Lost Arrow: Financials, Exhibit III) we have been operating in the black for the last decade. This may also be explained by our company ethic. We focus on a curbing of consumption and that focus has limited how much we are willing to spend on advertizing. Conversely our competition holds advertisement as a high priority when establishing sales and brand. This observation is not trivial and could more than account for the balance between our costs and those of our competitors. 3. Moving Forward As discussed the current model for Patagonia works. You can be a â€Å"dirtbag† and make make money. The question is how do we continue on with the goal of 10% growth per year for the next five years? Whatever we choose we must operate within that moral fiber that helped us to achieve who we are today. Following are two suggestions for how to move forward, one uses our current business model, the other proposes a change. Please reference Exhibit I for business model analysis and Exhibit II for strategy. Strategy: Current Business Model Tactic One: A Focus on Retail – Our best margins are derived from retail sales however this accounts for just one third of our sales volume. The best type of marketing asset we have are our retail employees. Our Dirtbag Ambassadors are out there skiing, snowboarding, climbing, camping, bouldering, and living the life that Patagonia wants to be an integral part of. We must expand our retail channel and focus on those areas where dirtbags convene. A quick review of the 26 stores in the United States can be found in Exhibit V. Portland, Seattle, St. Paul, Chicago, Atlanta, DC. Sure dirtbags live in cities but where are our stores in Telluride, Tahoe, Bend, Cheyenne, or Buffalo? An expansion of our retail stream increases profitability as well as the reach of our marketing, the Patagonia way. These are the places our competitors don’t wants stores for lack of traffic, but our stores are more than commerce they are community centers for dirtbags. Tactic Two: Research and Development – Our industry ethic has produced one of the best research and development laboratories in the industry. We can leverage this in two ways. First and foremost we must fund research to produce material with the ethical and physical integrity that also helps lower our gross margins. We have pioneered ethical durable material in the industry, now we must find a way to do so cheaper. Doing so would open up the market for those dirtbags who dont have as much money and would normally go to a competitor based on price point. Second we hold patents for these materials we could offer to sell material to other outdoor companies, or begin a joint venture. In either of these cases we must make sure that the material we produced is being utilized in an end product that is up to the standards of Patagonia. Strategy Two: A New Business Model There comes a time in a business’ life when you have to ask: While what we are doing has worked, how long will it work? To achieve the goal of 10% growth per year we may have to think outside of our wheelhouse and think about how committed we are to our ethical and social standards. As long as we continue to produce more clothing people will buy it. As it stands our customer base has expendable income. How can we convince them to only buy what we need? Through an expansion of our clothing repair services and clothing swap market. A case is made for the business model change in Exhibit I. Tactic One: Expansion of Repair and Retail – It is not our goal to abandon what has made Patagonia the company it is today, thus once again we will need to expand retail stores however we do so in a way that will facilitate clothing repair. Each store should have a mending workshop staffed and equipped to repair what comes their way. To really take advantage of this service we must willing to mend non-Patagonia clothing. This will do two things: it will reduce the overall number of unnecessary purchases in our market and it will introduce people to the Patagonia lifestyle through our retail store. These store can also facilitate a recycling program for those articles of gear that are beyond repair. Something as simple as an in store credit can get people who would otherwise go to Nike experience Patagonia C&A. Additionally the expanded retail presence will be an opportunity to create a network for clothing swaps Tactic Two: Expansion of Internal Repair – Expand the repair infrastructure behind retail presence. That is to say, as opposed to expanding retail and having repair work centers in-store, invest in larger repair facilities that stores can send garments to. In our current business model we are reaching critical mass with regard to how much clothing repair we can handle. If we strategically place lager facilities near our exiting stores we can handle this work load our selves. This also ensures that the materials and process of clothing repair is within the ethical conduct of our company without having to do audits of our outsourced partners. The clothing repair infrastructure for our market is basically nonexistent at this point and with research and development focused on this new business model we can create and dominate this market. This will once again involve repairing more than just Patagonia products but in the end that’s what this business model is about. To survive and grow into the next decade we must not just reduce the consumption of our customer base but we must reduce the consumption of our competitors as well. When a dirtbag holds on to a coat for another year he helps reduce Patagonia’s impact on the earth and its inhabitants. When Patagonia repairs a Columbia or North Face coat and it lasts for another year we have slowed the consumption of unethically produced clothes and possibly created another dirtbag. Exhibit I: Four Components of Business Model Framework (Johnson, Christensen, Kagerman) Customer value proposition (CVP): Current: Providing high quality durable outdoor athletic clothing and accessories (C&A) produced with a high standard for environmental and social impact. Proposed: In addition to production, engage the consumer in the environmental and social impact of their outdoor athletic C&A by involving them in the maintenance/repair/swap of C&A. Profit formula: Revenue model: Current: Standard industry mark up on goods sold. Proposed: Lower the price of goods sold and charge a small fee for repairs or continue with current price structure charge cost for repairs of Patagonia clothing/accessories, charge premium repair rates for non-Patagonia clothing and accessory repair. Cost structure: Current: COGS = 80% materials 20% parts with a wholesale margin of 45% and a retail margin of 65% Proposed: A modified cost structure that emphasizes retail sales and profits off of repairs Margin model: Current: Largest channel of sales in wholesale 44%, second retail 33%, and finally Catalog/internet 23% Proposed: Shift focus from wholesale to retail/catalog/internet sales, add additional emphasis on repair cost structure for maximum profitability Resource velocity: Current: In general keeping inventory exhausts resources, something which Patagonia wants to minimize. Thus production should match as close to demand as possible. Assets should be available, although they do not need to be incredibly liquid. Proposed: Same as current model. Key resources. Current: People: There is a certain type of person who works for Patagonia. Ideally a person who works at Patagonia is the ideal consumer of their goods. Brand: With a strong brand associated with high environmental and social standards combined with a strong dislike of standard advertising channels for the industry the reputation Patagonia’s brand has gained is remarkable (this is achieved through the people they employ as well). Technology: Their ethical commitment to responsible sourcing and production has resulted in some profitable patents of great C&A material. Proposed: The current Key Resources should not be lost but the Technology will shift to the new business model – a focus on materials , threads, and substances for repair. Additionally there would be a re-purposing of Facilities to reflect this model change as well. Key processes. Current: Rules and Norms: Patagonia’s Rules and Norms inform every aspect of their business and it is no different when it comes to their Key Processes. So while manufacturing, service, and training are all important, it all comes down to the Rules and Norms. Propsed: This would not change. When a new business model is needed. 1. The opportunity to address through disruptive innovation the needs of large groups of potential customers who are shut out of a market entirely because existing solutions are too expensive or complicated for them. The product repair market is just this. As it stands now such jackets tend to be luxury purchases as they hobbies they are designed for are not generally cheap ones to keep. 2. The opportunity to capitalize on a brand new technology by wrapping a new business model around it or the opportunity to leverage a tested technology by bringing it to a whole new market Patagonia isn’t capitalizing on a new technology when it comes to C&A per se but the market could motivate their R&D department to develop a technology that could be incorporated into the repair model. 3. The opportunity to bring a job-to-be done focus where one does not yet exist The expansion of clothing repair for Patagonia and other non-Patagonia C&A provides a real opportunity for an existing market that consumers may not know they need. It creates a job to be done (clothing repair as opposed to replacement). 4. The need to fend off low-end disrupters. Patagonia would be a low end disrupter in the repair market; repair is cheaper than replacement. 5. The need to respond to a shifting basis of competition. Patagonia would be shifting the basis of competition.

Impact of Thomas Jefferson on John Adams based on David McCullough's Essay

Impact of Thomas Jefferson on John Adams based on David McCullough's bioigraphy - Essay Example Both men reveal an ongoing influence upon the other. In the later years, the author hints of a vilification of Jefferson to Adams in the mind of the popular press, yet the text itself implies otherwise, describing situations with a latent sympathy to the old comrades. Specifically, this paper will examine several key comparisons of the text which impart a moral description of Adams through ertain excesses of Jefferson. Jefferson is first introduced at the gathering of the Second Continental Congress, an opportunity the author uses to make a physical comparison with Adams, for where Adams was "stout, Jefferson was lean Where Adams was bald, Jefferson had a full head of thick coppery hair" (111). McCullough lists a number of other comparisons, of which the two most important ones were Adams hailing from Massachusetts while Jefferson came from a financially well-off Virginian aristocracy, thus, while both were extremely practiced in law, "Jefferson had never relished the practice of law as Adams had, nor felt the financial need to keep at it." (114). Jefferson is portrayed as speaking very little at this Congress, being deferential to Adams in almost all matters, although the gentlemen in general held a mutual respect and admiration for the other. Jefferson's assignment to write the Declaration of Independence is addressed by both men many years later. Jefferson recalls that he was asked and agreed, Adams claims that Jefferson tried to pass the work onto him (Adams), but that Adams refused for three reasons: 1) because that a Virginian representative should be involved in the forefront of the endeavor, 2) Adams saw himself as obnoxious and unpopular (a self-deprecation otherwise non-existent) and Jefferson the opposite, and 3) that Jefferson was the better writer. Despite Adams and the rest of the drafting committee, making minor changes, Adams promoting the skill of Jefferson's writing has proven to be a boon to successive American generations. When Jefferson was chosen as an ambassador to France in 1782 and sent to join Adams and Benjamin Franklin, who were already posted in Paris, Adams lauds the selection, claiming no one else compares to Jefferson character "in point of power or virtues." (318). This warmth is wholly absent from an earlier letter Jefferson had sent to James Madison, saying Adams's "vanity is a lineament in his character (and) his want of taste I had observed" (318). Despite some waffling, however, Jefferson does admit to Adams's integrity and usefulness in the position. To be fair, Jefferson was just leaving an unwelcome stint as governor of Virginia, a tenure culminating in his narrow escape from British invasion. Perhaps his vehemence in describing Adams is therefore related to an attempt to inflate his own worthiness, a latent desperation to receive the posting himself. For upon his arrival in Paris, Jefferson resumed very close relations with the entire Adams family. McCullough does point out a dis tinct difference in lifestyle here, for Jefferson, rather than assuming the modest lifestyle of the Adamses and living on the outskirts of the city, instead takes an apartment in the heart of the city and goes on wild shopping sprees. He lives in such a constant state of

Risk management cycle and strategy of Money laundring in the US Essay

Risk management cycle and strategy of Money laundring in the US - Essay Example This research will begin with the statement that the issue of money laundering has been the center of debate for quite a long time. Criminals and other terrorist groups have continued to use money-laundering schemes to hide their intermittent sources of money obtained by fraudulent means. According to the Office of the Foreign Assets Control, the United States continues to lose large amounts of dollars through money laundering activities. The country is also facing imminent risk of ever-lasting criminal and terrorist threats since the rate of money laundering activities is still high. As of today, economists in association with financial analysts fear that the United States will face an unimaginable loss of foreign investors in the not too far future mainly because of money laundering risks. This is so because the presence of money laundering activities brings about significant risks, which tarnishes the safety and soundness of a country’s financial industry Typically, money l aundering is simply the process in which an individual or a group conceals the source where they obtain money via illicit means. The ways in which fraudsters can launder money are several and they can vary in accordance with their sophistication. Every year, the government of the United States quotes the amounts of money that the country loses through money laundering activities. Given that most of the money obtained through fraudulent means goes to fund criminal and terrorist operations, it is agreed that the risks involved in money laundering expand to encompass the safety and security of the nation. As a result, the United States is likely to be sitting on a time bomb since anti-money laundering agents are moving at a slower pace, unlike fraudsters who are at the verge of compromising the face value of the United States’ financial sector. Recently, the International Monetary Fund’s report revealed that two to five percent of the world’s general economy is com posed of laundered money. Nevertheless, the task force charged with the duty of combating money laundering business, commonly referred to as the FATF, communicated that it is not easy to provide an estimate of money obtained through laundering.

Individual project 4 Essay Example | Topics and Well Written Essays - 500 words

Individual project 4 - Essay Example Experience in the process: Prior work experience may not always be a criterion in the selection process while filling a vacancy. But it becomes a criterion when the post requires handling of some specialized activities which only an experienced person can handle or when there is not enough time to train a fresh candidate for the post. Prior work experience is mandatory when the recruitment is for top level managerial jobs. Communication skills: Communication skills are a mandatory criterion for most jobs. It is essential for better performance on the job. No business deal is made without an effective communication. Therefore, it is important that every individual at the core positions possesses good communication skills. For almost all the jobs, communication skills are an important selection criterion. Advantages: The main advantage for external selection for this post is that a wide choice of potential candidates is available. The company can get a pool of qualified and experienced personnel for the position from which they can select the best one. The second major advantage is that it will help to bring in new ideas. A person who has experience as store manager in some other company may bring in ideas that were used in the other company which can be helpful to our company. (Peterson, 2012) Disadvantages: The first major disadvantage is the higher cost involved in the process. External selection for the post requires advertisement and several other screening processes thereafter. This will incur higher cost than internal recruitment. Moreover, external selection is a time consuming process. Another major flaw in this selection is that the existing employees below the store manager level will feel de-motivated because their chance for advancement is being hindered. (Riley, 2012) Advantages: The Company need not incur much cost for selection as the resources are readily available in the

Busines Environment Essay Example | Topics and Well Written Essays - 2000 words

Busines Environment - Essay Example Suppliers refer to the companies that directly sell electric power (About the Electric Industry, 2011). Thus the electric industry in the UK can be understood to perform its functions effectively with the help of these stakeholders and have proved to be efficient over the years. However, with the increasing levels of competition in the industry, it has been found that customers have changed their preferences of suppliers. Also, increasing level of prices have led to the consumers plan for savings and hence cutting down on consumption. Thus in the recent years, the UK energy prices have been found to fall down (About the Electric Industry, 2011). The current study focuses on a PEST analysis of the UK electric power industry and hence determines the recent changes that have occurred. Earlier the electric power industry in the UK was under the control of the Central Electricity Generating Board (CEGB). When CEGB was in control of the electric power in the UK, there was not much competition in the market. There were 12 boards in the regional areas that were in charge of the electricity distribution. Also the prices during this time were lower for the consumers to afford. The system being dependent on thermal generation was responsible for around 70 percent of the total production of electricity. With the process of privatization the controlling board was considered to be privatized. Private ownerships and competitive pricing became parts of the new privatized industry that was created in the year 1990. In the new structure the independence of the generators were limited and central planning was lacking in the development of capacity. The prices for the power supply also increased although for significant power consumers the prices reduced after inflation (Stevens, 1995, pp.52-59). Although the new system have several advantages like reduced labor costs, better customer services, reduced borrowing from government as well as alteration in the business culture,

Stylistic analysis and history in art Essay Example | Topics and Well Written Essays - 500 words

Stylistic analysis and history in art - Essay Example Legon claims, â€Å"The Egyptian canon of art was metrological founded through the system of horizontal guidelines that established the canonical forms† (Legon Web). The most appealing nature of the image that looks Egyptian to me is the choice of colour. The colours used in the image are a true reflection of Egyptian artwork. â€Å"Cannon of art† refers to classification of art by early historians. This early classification still has its influence in the naming of today’s art. In the topic "Discrimination in the Arts in America," â€Å"Cannon of art† is present. The early historians in America supported hierarchies of race due to the alleged evidence from the book of Genesis chapter nine in the bible. Noah blessed his son, Shem who covered him of his nakedness when he was drunk and cursed Canaan, Japheth was blessed to expand. Christian fundamentalists believed in the three races, White representing Japheth who was to expand to other nations. They justified slavery of Africans on this and believed that the whites should take the highest positions that existed. The cannon of art for Americans had a background of racism, which many art historians represented in their work. They did this via colour since the three different races had three distinct colours; white, yellow, and black. My choice of a retablo is the painting of Virgin Mary by Frida Kahlo made in Mexico. Like most of the retablos made during the 18th century, the Virgin Mary retablo was made in honour of the Catholic saints (Castro-Sethness 21-23). Virgin Mary is one of the most honoured spiritual personalities in the Catholic Church in prehistoric times and even at present. The most important learning from the Virgin Mary retablo is that the people who existed in the period in which the retablo was made had a significant connection to the church (Nolan 15-20). Most notably, they valued the saints and therefore, preferred preserving their images in form

INDIVIDUAL PROJECT 3 Essay Example | Topics and Well Written Essays - 1250 words

INDIVIDUAL PROJECT 3 - Essay Example Issues such as development of new departments and work process flows are considered as potential threat by the existing employees because they might feel that they may be rendered as useless due to redundancy of their skills. Modern managers therefore have to manage different aspects of change management in order to ensure that the new changes that are being introduced within the organization are readily accepted with little or no resistance. For this, it is also critical that the employees are considered as a part of the process and as such any change that is brought about shall be floated as an indigenous idea which can only facilitate the existing work. The recent changes at SWC indicate the recent efforts to bring in new and positive change might not have been gone well with the employees and there is a growing need of having a change management plan that could have allowed the firm to make a swift transition to the proposed new structure and developing a new framework for future. It is believed that change always occur first into the heads of the people and than it is translated through changes to be made into the people, processes as well as systems and activities. Organizations often have to manage change in a manner that can allow them to achieve their strategic objectives. The psychodynamics of the change management therefore requires that the managers must contextualize the change in a manner which reflects the change as an indigenous process of change rather than something which is being imposed externally. (Carr & Gabriel, 2001). In order to make change, It is therefore important that one must also understand the change and for that matter, the issues such as change imperative, the psychology of change as well as resistence to change must be understood in their true spirit in order to bring in change that can be easily accepted. (Harris & Crane, 2002). This therefore also requires that the whole process of

Businesses and International Strategy Essay Example | Topics and Well Written Essays - 5000 words

Businesses and International Strategy - Essay Example This has made it necessary to conduct research across boundaries as it helps to identify regional and global market segments. As firms need to collect information from a broader and more diverse range of markets conducting research in developing countries has become essential. However, conducting market research in developed countries poses certain challenges. These challenges range from collecting accurate and updated data on existing behavior patterns in a cost-effective manner. Collection of data has become easier due to technological advancement but also complex at the same time. The communications infrastructure enables data collection on a much broader and diverse scale. The removal of barriers between countries, the growth of regional and global market infrastructure and the increased mobility of consumers have exerted pressure to have an integrated international marketing strategy. The emerging economies are promising in terms of sales and expansion of the multinationals and hence conducting international market research in these countries is of paramount importance. Before entering these markets, firms have to collect information to assess potential opportunities and determine how to position, price, promote and place their product. International Marketing Research (IMR) has been defined as market research conducted either simultaneously or sequentially to facilitate marketing decisions in more than one country (Kumar, 2000). The process entails taking into account various market characteristics for facilitating marketing decisions. The various components that are responsible for marketing the product can be traced. Marketing research is an important part of the marketing intelligence system as it helps to improve management decision making by providing relevant, accurate and timely (RAT) information (Aaker, Kumar & Day, 2001).

Unmanned Aerial Vehicle Ground Support Equipment Business Proposal Essay

Unmanned Aerial Vehicle Ground Support Equipment Business Proposal - Essay Example Unmanned Aerial Vehicle supports both war missions. Mission success depends on the airworthiness of the aircraft. Every aircraft are suspected of structural degradation throughout its lifetime. Maintainers of the aircraft require equipment that has already been tested and safe for use. The second part of our business will focus on providing replacement parts for the ground support equipment. Ground support equipment is required to safely handle aircraft parts. Nine out of ten aircraft parts will be transported from the hangar to the field. Ground support equipment will provide that ease. Mission Statement Our mission is to build, create and implement a safety program that would meet our aviation communities’ expectation. Our product will be the end result of our mission statement: quality. We also have high expectations of being a manufacturer who will guarantee high value; high quality and we will exceed our customer’s expectations. Executive Summary I propose that our company would be called FUGENAV. I combined the word future, generation and aviation to come up with FUGENAV. This is only my proposal and is subject to change upon request. The United States military are wide spread across the globe. I propose that we stay within close proximity to the busiest military airfield. The busiest military airfield is located on Fort Bragg, NC. We could sell our products and ideas to the military as a startup. We would provide demonstration and loan some equipment with a fee. General support equipment could be used to transport an aircraft parts. Aircraft are disassembled down to the fuselage. All aircraft parts must be stowed away properly so that damages does not incur. Unmanned aerial vehicles are small enough that we could build trailers to move the aircraft from point A to point B. There are an abundance of ideas that we could use to support the different types of unmanned aerial vehicle. We could build ground support equipment tha t pertains to the different types of unmanned aerial vehicles. There are over fifteen different types of unmanned aerial vehicles used today. For example, I will list the different types of unmanned aerial vehicle used by the US military today: US Air force: Wasp Block III Gnat 750 MQ-1 Predator MQ-9 Reaper RQ-4 Global Hawk RQ-3 Dark Star RQ-170 Sentinel US Marine Corps: Dragon Eye RQ-11B Raven B RQ-2 Pioneer US Army RQ-11A/B Raven RQ-7A/B Shadow 200 RQ-5A MQ-5A/B Hunter MQ-1c Gray Eagle Any aircraft require periodic maintenance to keep them airworthy. Every aircraft listed is build and designed differently. I believe we could provide the right equipment needed to conduct safe maintenance. We would provide the equipment that is safe and user-friendly. Our product will be built with quality, two year warranty, provide training to properly use the equipment, and develop good relationship with our customers. Introduction The rationale of this business plan is to delineate the goals we will pursue for the foundation, development and operation of an aviation ground support equipment safety program. All aviation equipment is required by FAA to be inspected for deficiencies so that it could mitigate risk. The US military, commercial airlines, and aircraft owners require ground support equipment to properly fix an aircraft. Our business will provide that service for companies like Boeing and the US military. FAA requires that products manufactured meet

A Taste of Honey Essay Example for Free

A Taste of Honey Essay Act two, scene one is an important part of the play because Jo is near the end of her pregnancy and Helen comes back to visit her but only because Geoff had asked her too. Previously in the play Helen had married Peter and had gone to live with him, Jo got engaged to a black boy in the Navy, she became pregnant but he didnt come back after going away with the Navy. Jo didnt have a very good relationship with her mother and they had moved about a lot as Helen ran every time she couldnt pay the rent. Jo met Geoff who is a homosexual. He hasnt had sexual relations with a man but he knows he is gay because he has had liaisons with other men. Jo has left school and was going to work in a pub part-time. The play is A Taste of Honey and I am doing part of Act two scene one where Jo, Helen and Geoff are the main characters. This play is mainly set in Jo and Helens flat where the time is around the 1950s. Helen and Jo werent very well off so the flat is in a poor condition. It is dirty and there is a lot of dust. The house looks like it is uncared for because clothes are on the floor and the bed isnt made. It is a comfortless flat. If I was in the audience I would see the settee in the middle of the flat with Geoffs bedding on it, to the left of the stage would be Jos unmade bed it might have some clothes lying untidily on top of it. To the right I would see the kitchen, the sink full of dirty plates and cups, and there would be lots of things scattered about the kitchen sides. In this section of the play the characters use actions in different ways to portray their emotions and feelings. For example: at the beginning of this section Geoff says Let me kiss you this lets us know that Geoff likes Jo as more then a friend unfortunately she does not feel the same way. This is shown when she struggles as Geoff forces himself on her. Another show of Geoffs feelings towards Jo are when he asks her to marry him, Jo just dismisses the idea and tells Geoff Im not marrying anybody. When Helen arrives she tries to be motherly towards Jo but Jo doesnt really want to know as Helen hasnt really been there for her whilst she has been growing up. I dont think she understands why Helen suddenly wants to be a proper mother so Jo starts an argument by saying what blew you in as soon as Helen comes in to the room. But Helen still tries to by friendly by asking about Geoff, she also tries to change the subject at that point when Jo asks her how she came to know about her pregnancy she replies Come on, arent you going to introduce me to your boy friend? Who is he?. I think at that point Helen hadnt come to argue with Jo and had come to see if she was alright. When Jo and Helen are angry they both speak their mind and tend to shout when arguing. Jo talks in a steady voice and when speaking to Geoff she talks in a soft voice but her voice is stern when she is speaking to Helen as I feel she is resentful towards her. Helen talks to Jo as if she regrets having her and wishes shed aborted her like all the others, in this scene though Helen starts off friendly but finishes by chasing Jo around the room trying to hit her. Geoff is the calm one; he doesnt stand up for himself much but tries to protect Jo. When Geoff is told to do something he does it without complaining. This play is important to theatre history, as it was the first play ever seen about real life and the problems that came with it like poverty, racism, teenage pregnancies and homophobia. This play had them all in. At the time this play was written Britain was just recovering from shortages and rationing, the rationing ended in 1952. Housing was scarce so many people had to live in flats even if they could afford better and bomb sites were still derelict. Shelagh Delaney was the author of this play and she was 19 years old when she wrote it. It was written in 1956 and censorship from the stage was removed in 1963. A Taste of Honey is what you would call a kitchen-sink drama because it is based on real life, problems, poverty and the working class.

How Important Are Fossil Fuels To Society Environmental Sciences Essay

How Important Are Fossil Fuels To Society Environmental Sciences Essay Thirst for knowledge is humans natural behaviour which has led to various inventions and discoveries. Humans need energy for doing all types of work. Without generating energy, all the luxuries of everyday life will come to an end. Fossil fuels, a remarkable discovery by humans have simplified our lives. However, the rate at which these resources are being depleted are threatening to run out soon. Fossil fuel usage began on a large scale with the introduction of industrial revolution in 1800s.Nowadays, a lot of alternative energy options are available, like wind , hydro , and sun energy. But ironically, majority of our energy is derived from non-renewable energy sources, which are commonly called fossil fuels. Like every other invention or discovery influence society, same applies to fossil fuels as well. In order to know how fossil fuels affect our society, one needs to examine it. Without fossil fuels, there wouldnt be any means of transportation, and the world and the economy would come to standstill. We need energy to heat houses, and energy is needed for agriculture and industries. Without fossil fuels, there would be no energy, no heat, and the cost on running on the alternatives would be a lot higher than what we have on fossils. Fossil fuels are comprised of hydrogen and carbon bonds. Coal, oil and natural gas, are the three kinds of fossil fuels used for delivering energy. With the increasing population, the demand for energy also increases, which increases the pressure on the environment. Another major variable, that threatens and pressurizes the energy sector to move into nuclear, solar and other environmentally friendly energy sources, is due to the fear of climate change. Coal, oil and natural gas supplies are forecasted to peak as the reserves are running out. Coal is a form of solid fossil fuel which is formed by decay of land vegetation. It is plenteous as compared to oil and natural gas. Forecasters predict every now and then, that the coal usage will increase as oil supplies becomes less. Present supply of coal might last about 200 years or more. Developing countries such as India and China, cant meet the expense of using natural gas or oil, and therefore depend on coal for delivering energy. According to IEAs world energy outlook forecast (2006), 85% of the increase in coal demand is likely to come from China. Coal consumption is predicted to increase by 1.4% yearly until 2030, with about two-thirds of the demands in India and China. According to the statistical survey done (2007), The coal consumption in 2006 was 3 billion tonnes. China, India, South Africa and Germany claimed to be the largest consumers of coal. The natural gas exploration is getting cheaper and big industries are switching to natural gas instead of coal which has other side problems, besides environmentally unfriendly. Oil is a liquid fossil fuel, formed from the remainders of marine micro-organisms deposited on the sea floor. Millions of years after, the deposits eventually end up in sediments and rock, in which oil is confined. Oil consists of a lot of organic compounds, which are altered into usable products by refining process. Oil is not found in all the places on earth, and there have been wars on oil supplies. Gulf war which happened in 1991, is a well-known example of this. The local production of oil has lowered since 1960.In 1970s the oil production has plunged reaching a peak point of 9.6 million barrel per day(Mbbl/d). Since then, oil demand has increased significantly such that industries supply less than half of all its oil that we consume. However there had been a radically change in consumption from 1960 to 1970 (from about 10 Mbbl/d to about 17 Mbbl/d) as shown in the figure. Moving to suburb and driving for miles caused an increase in consumption which was a turning point in American societys lifestyle. Nevertheless, during 1970s, demand levelled off and then declined suddenly as oil prices increased to over a dollar per gallon from $0.25. Since 1980s, oil demand has grown progressively as prices stabilized while inflation continued to grow. Currently we sit at 19.6 million barrel per day in U.S. which is about 25% of the worldwide consumption of 77 Million barrels per day. Natural gas is a gaseous form of fossil fuel which is versatile, available in plenty and relatively cleaner as compared to the oil and coal. Like oil, it is also formed from the remainders of marine micro-organisms. Natural gas is made up of methane, and is highly compressible, and is drilled to bring it on the earths crust. More coal was used until 1999, than natural gas. It has surpassed coal now in developed countries. However, humans are frightened that natural gas supply will eventually run out, like oil and coal. Predictions say that this might take place at the end or the middle of the 21st century. Unlike oil supplies, Natural gas reserves are distributed more uniformly around the planet. Energy produced by combustion of fossil fuels is converted to heat and electricity in power plants. On combustion, carbon and hydrogen reacts with oxygen to yield carbondioxide and water with heat. Electricity is produced by transforming this heat into electrical energy in a generator. Although, building a power plant needs a lot of money, the efficiency it delivers to convert fuel into energy is very high, and is worth the money spent to build it. The demand of electricity varies throughout the year, and provisions should be made to meet the demand in peak load. When the demand surpasses the capacity of power plants to generate electricity, momentary blackouts are experienced. In 2001, California experienced shortage of electricity, drawing attention to the crude oil and natural gas shortage. In the past, fossil fuels were present in abundance and were easy to obtain and deliver. The present trend of using these energy resources by mankind is one of the important issues questioning its long term sustainability. We have created a horrible situation for ourselves, by denying the fact that these resources will not be running low, and trying to run away from the reality rather than facing it. People are afraid of the consequences of what may happen if the fossil fuels actually run out. Fossil fuel combustion contributes to a lot of environmental issues that are also high on political agenda these days. Examples of these issues include emission of greenhouse gases, acid rain, air and water pollution, and ozone at ground level. These environmental concerns are caused by the burning of fossil fuels, which produces impurities like nitrogen, sulphur, and organic volatile compounds. These bi-products influence people and our atmosphere in many harmful ways. Like a glass in a greenh ouse, these pollutants build a barrier and prevent the excess heat from earth to escape. The temperature of the earth increases with the increase in this barrier, resulting in global warming. Global warming has become a serious issue, which could threaten our existence. Have people ever thought that why Antartica experienced the warmest years in all of history? Have people thought of rising sea level, which resulted due to melting of ice? The intensifying sea level could lead in floods and hurricane. If these changes are not enough to alert humans, the effect on agriculture around the world might be frightening. Production of maple is decreased by 10% because of warmer and shorter winters. A study comparing the yields of six main staple crops was done at the Lawrence Livermore National Labs and Stanford university. Study showed that for every one degree rise in temperature, there will be a decline of about 3% to 5% in the yield of those crops. Those six crops is responsible for abou t 55% of non-meat calories consumed by people, and about 70% of the animals feed all over the world. Acid rain is caused by the emission of sulphur and nitrogen, by burning fossil fuels. Acid rain is a combination of dry and wet deposition from the sky which contains higher amounts of nitric acid and sulphuric acid than normal. It makes the lakes and streams acidic, which leads to destruction of trees at higher altitude and soils. Acid rains also contribute to the decay of buildings and sculptures, decreases the visibility and have harmful effects on publics health. Acid rain not only cause damages where it falls, but it affects all over the planet, since lakes and streams transport the water throughout earths crust and finally to the ocean. The plants and animals that are dependent on this water to survive are affected and may decease if the chemicals in the water are present in extreme excess. Another problem resulting from fossil fuel usage is Air pollution, resulting in smog. Apart from human sickness, smog also affects the crops, by seeping through the leaves protective layers and destroying the essential cell membranes. This makes the crops weaker and decreases its yield. Combustion of fossil fuels produces nitrogen and other organic gases that form ozone. Ozone is formed near the surface of the earth causing air pollution. According to the CESI report (2006), Ground level ozone has affected the health of Canadians including respiratory problems, cardiovascular diseases, premature deaths and over 6000 hospitalizations. All above discussed issues are caused by the emission of impurities that are present in the structures of fossil fuel .Presently, combustion of oil accounts for about 30% of carbondioxide in the environment. The maximum emission of pollutants is caused by the burning of coal. Natural gas consists of methane structure, due to which it doesnt emit as much carbondioxide as compared to oil and coal. The question arises, that looking at these consequences, why are we still using fossil fuels to such large scale? The answer is simple; because fossil fuels are comparatively cheaper than using alternatives we know so far. People have made their lives so much dependable on fuels, that if these run out, the human civilization will come to an end too. Also, digging fossil fuels from earth surface is dangerous, as digging of mines and wells could result in change of surroundings and may fetch immense quantity of salt water to the earths surface, which can result in damaging the ecosystem in clos e proximity with no appropriate treatment and sequestration. There are procedures to follow to minimize the hazards, but it is hard to completely eradicate them. However, regulations are not enough, we should continue researching new technologies for fossil fuels and renewable sources both, to add increasing conservation measures. Few environmentalists predict that because of insufficiency, fuel prices will increase exponentially in the coming century. We cannot completely stop using fossil fuels, but we must make some changes in our consumption pattern by avoiding oil products and favouring available alternatives for our sustainability.

Chronic Obstructive Pulmonary Disease (COPD) Literature

Chronic Obstructive Pulmonary Disease (COPD) Literature This essay focuses on the search and exploration of three pieces of literature related to Chronic Obstructive Pulmonary Disease (COPD). This includes one government guideline and two research articles covering different nursing angles of the condition. An analysis of how the search was conducted, the main findings and rationale for the chosen articles. Finally, a demonstration of understanding with the use of additional literature to analyse, identify and explore how it will influence the nursing care of patients with COPD. Search Strategy. PubMed was the chosen search database as supposed to other databases like Cumulative Index to Nursing and Allied Health Literature (CINAHL) because PubMed presented more articles with clear and precise titles, therefore enabling the writer to identify its significance (Macnee and McCabe, 2008). The writer firstly chose a topic, which was ‘self-management for people with Chronic Obstructive Pulmonary Disease’. Harvard (2007) further suggests that when conducting an effective and valid literature search it is important to identify a topic to enable the search results to be applicable and relevant. In-order to be more specific the writer identified key words from the chosen topic, and implemented Boolean operators, which concluded to ‘Self-Management AND COPD’, this was inserted and resulted to 1127 hits. According to Barker, Barker and Pinard (2011), Boolean operators such as ‘AND, OR, NOT, AND NOT’ are simple words used to join or exclude key wor ds in a search. PubMed included search options such as full text and abstracts available, language, age range, gender and publication dates which were utilised to enable the user to narrow the search to an optimal amount (refer to Appendix 1 and 2). The search was narrowed from 1127 hits to 95 hits, from which this article was selected, titled ‘Self-management support for moderate-to-severe chronic obstructive pulmonary disease’. This article was chosen because the authors used current evidence to support and justify the outcomes and findings of their study. Boswell and Cannon (2011) suggest that a research study that incorporates current and relevant evidence to analyse their study is more likely to be reliable. The second research article was selected using different key words, which was ‘Pulmonary Rehabilitation AND COPD’. The writer retained the same search options used to find the first article, this narrowed the search to an ideal amount, from 479 to 38 hits (refer to Appendix 1and 2). This article was selected because it identified the importance of pulmonary rehabilitation in connection to improving quality of life and reduced hospital admissions. The authors validated their aims by analysing current evidence that supports the need to promote pulmonary rehabilitation for COPD patients following a discharge from hospital. United Kingdom. National Institute for Health and Care Excellence. (2010). Chronic Obstructive Pulmonary Disease: Management of Chronic Obstructive Pulmonary Disease in Adults in Primary and Secondary Care. London: NICE. The National Institute for Health and Care Excellence (NICE, 2011) released a guideline titled ‘Chronic Obstructive Pulmonary Disease: Management of Chronic Obstructive Pulmonary Disease for Adults in Primary and Secondary care’. The writer was able to find this Guideline simply by inserting ‘Chronic Obstructive Pulmonary Disease’ into the NICE database, which resulted to 138 hits. The writer then narrowed the search by selecting ‘Guidance’, which is an option provided; this further narrowed the hits to 37, from which this guideline was selected. This guideline defines COPD as a chronic disorder caused by frequent airflow obstruction with symptoms like persistent and progressive breathlessness, chronic cough and limited exercise ability. It is estimated that COPD is UK’s fifth biggest killer with 3.2 million people living with the condition, this support the importance of delivering high quality care, which NHS England (2014) defines as providing a positive experience of care that is clinically effective and safe. The National Institute of Health (2013) further suggest that there is yet to be a cure for this disease. The aim and objectives of this guideline is to offer the best professional practice advice on a patient centred approach to caring for COPD patients. The British Lung Foundation (2013) additionally suggests that this guideline will help the health care professionals such as the nurses to identify the types of care COPD patients should be receiving, as they are frequently the first point of contact and are involved in all aspects of care. NICE (2011) guideline also defines the symptoms, signs and investigations required to establish a diagnosis. Bellamy and Smith (2007) support that the key to early diagnosis is recognising the signs and symptoms such as frequent coughs, chronic sputum production, breathlessness and a history of exposure to tobacco smoke to aid in diagnosing the patient. The guideline also looks at the necessary factors to assess the severity of the disease and guide best management in both acute and community settings so that it is applicable to all settings and professionals. This guideline was chosen because it considers most issues that are important in the management of people with COPD, integrates published evidence in areas of uncertainty that could possibly need further research and is useful to all professionals involved in the care of COPD. According to British Lung Foundation (2013) the management of COPD is challenging, as the patients have complex health and social needs requiring long-life monitoring and treatment, Fletcher and Dahl (2013) go further to explain that nurses in comparison to other health professionals are more involved in the care and management of patients with COPD. Therefore, this guideline positively influences the nursing care of patients with COPD by providing information about the basic level of care required and empowering COPD patients to make decisions over their health and care needs (DOH, 2013). Taylor, S., Sohanpal, R., Bremner, S. A., Devine, A., McDaid, D., Fernanded, S. L., et al. (2012). Self- Management Support for Moderate-to-severe Chronic Obstructive Pulmonary Disease. British Journal of Medical Practice, 62. (603), 687-695. The authors study is focused on the importance of self-management education and its contribution to a better quality of life and reduced hospital admission. According to The Health Foundation (2014), self-management education is aimed at improving how people with COPD are supported and empowered to self-manage. The authors aim was to explore the cost effectiveness of self-management programmes and education for COPD. The author’s findings suggest that COPD patients feel useless and helpless to self-manage their condition, therefore the programmes plays a vital role in improving the patient’s quality of life, exercise tolerance and empower them to take control over their health which in turn will reduce exacerbations and rapid deterioration. The outcome of this study has a good chance to meet the UK National Health and Clinical Excellence (2010) criteria on cost-effective approaches to managing COPD. This information could be useful to nursing patients with COPD by underlining the importance of Self-management education, which may include working closely with primary care teams and educating the patients on self-management techniques, like learning to control breathing, being mindful of tiredness due to over exertion on daily activities and eating a well-balanced diet. This would contribute towards living better with the condition (COPD Education, 2014). The authors recognise that nurses play an important role in educating, equipping and supporting the patients to merge their everyday life to suit their long term condition, such as dealing with an altered view of the future and the frustration and depression that may result (Redman, 2004). Part of the nursing care, with patient participation includes creating a short-term personalised action plan, which would be closely monitored to enable the nurse to identify the strengths and areas of development. Fletcher and Dahl (2013) ackn owledges that the purpose of self-management education is to empower patients to improve their health and to restore the highest level of function regardless of the disease stage or following an exacerbation. Cosgrove, D., MacMahon, J., Bourbeau, J., O’Neil, B. (2013). Facilitating education in pulmonary rehabilitation using the living well with COPD programme for pulmonary rehabilitation, 13. (50), 13-50. The author’s presentation of their study, based on the importance of facilitating education in pulmonary rehabilitation was clear and precise as the reader was able to gain a good understanding of the study. Galin and Ognibene (2012), go further to support that a good clinical research study should not be full of medical terminologies, and should be presented with clear and accurate information enabling the reader to grasp the key elements. The author’s aims of the study were to adapt a self-management programme which was Living Well with COPD (LWWCOPD) through pulmonary rehabilitation and then to evaluate its impact. They identify that pulmonary rehabilitation administered after an exacerbation can reduce hospital re-admission and improve the patient’s quality of life as supported by Seymour et al (2010). The author’s findings suggested a positive outcome for the patients, as they felt they were in a friendly and supportive environment to be empowered to manage their condition, especially coping with breathlessness. The British Lung Foundation (2013) supports this evidence as they additionally suggest that pulmonary rehabilitation programmes are designed to help people with COPD to cope with breathlessness and to feel stronger to manage with activities of daily living such as walking, personal care and eating, as they often feel disempowered to self-care. This information could be beneficial to nursing patients with COPD by emphasizing on the importance of evidence based nursing practice to enable accurate and useful information when recommending relevant programmes, which contributes to their on-going care (Deutschman and Neligan, 2010). It is estimated that most patients with COPD will experience at least one hospital admission due to an exacerbation of their condition within three months (DOH, 2012). Therefore based on the information from the Study which suggests that pulmonary rehabilitation reduces hospital re-admission, the nurse plays an important role in encouraging the patients to join the programme which is designed to suit the individual. British Lung Foundation (2013) goes further to suggest that the course will teach the individuals how to increase their exercise tolerance, cope with breathlessness and manage periods of stress and panic. Additionally pulmonary rehabilitation can be beneficial to COPD patients socially, a s it involves interacting with trained professionals and other COPD patients, as due to the nature of the condition social interaction may be difficult (Bellamy and Booker, 2011). In conclusion, this essay has explored three pieces of literature related to COPD with additional evidence to analyse identify and explore how it will influence the nursing care of patients with COPD.

Behaviors Caused by Hypothalamic and Thalamic Lesions :: Neurological Chemistry Chemical Papers

Behaviors Caused by Hypothalamic and Thalamic Lesions In the field of neuropsychology, the area in the brain that includes the hypothalamus, the thalamus, and the subthalamus is referred to as the subcortex diencephalon (Kalat 2004). In the following section, lesions to these specific areas will be discussed. The results of the lesions will be addressed from the perspective of a neuropsychologist. Neuropsychological assessment refers to the objective evaluation of the cognitive, linguistic, perceptual, and psychomotor performances of a person with the aim of relating the status of his/her performances to the structural and functional condition of his/her brain (Steinhauer, Gruzelier, & Zubin 1991). Neuropsychological assessment can be approached from an experimental method in which the researcher has greater control of the variables affecting the situation but, generalization is more difficult and human subjects cannot be used in studies (Finger 1978). A clinical method is also used and, although this method does not experience the benefit of complete control, brain-behavior relationships are much easier to study because human subjects can be used in this method (Finger 1978). Both methods are usually combined to produce the most efficient and helpful information for the patient. The most prominent neuropsychological tests include the Wechsler Adult Intelligence Scale, the Halstead-Reitan battery, and the Wechsler Memory Scale (Steinhauer et. al. 1991). These tests provide the opportunity to analyze the components of performance and then identify probable disabilities that would explain the defective performance (Steinhauer, et. al. 1991). The main issue that will be examined in this section will be behavioral effects of lesions to specific parts of the hypothalamus and the thalamus. The hypothalamus is located near the base of the brain and is ventral to the thalamus (Dimond 1978, Kalat 2004). The hypothalamus is part of the limbic system and is responsible for motivational behaviors including emotion, eating, drinking, sexual activity, anxiety and aggression (Kalat 2004, Dimond 1978, Isaacson 1982, Beaumont 1983). The hypothalamus has widespread connections to the rest of the forebrain and also to the midbrain (Kalat 2004). The hypothalamus contains a number of distinct nuclei including the lateral nucleus which controls the initiation of eating and drinking, the ventromedial nucleus which controls the stopping of eating and drinking, the paraventricular nucleus which limits meal size, the supraoptic nucleus which controls the secretion of vasopressin, the suprachiasmic nucleus which constitutes the biological clock,

Life Of Fredrick Douglass :: essays research papers fc

Breaking the Shackles   Ã‚  Ã‚  Ã‚  Ã‚   If there is a theme that has been present in writings since the beginning of time, it is discrimination. Since the creation of man, discrimination has been a problem in society. The theme of discrimination is illustrated through the novel, Narrative of the Life of Frederick Douglass; the essay, “Indian Civilization Vs. White Civilization;'; and the speech, “I Have a Dream.'; The theme of discrimination is clearly present in Frederick Douglass’ Narrative of the Life of Frederick Douglass. Frederick Douglass was born in Tuckahoe, Maryland around 1818. He had no accurate knowledge of his age. Douglass was born to a black mother and a white father, who he believed was his master (Douglass 19). By secretly studying books, Douglass learned to read a crime punishable by death. He escaped slavery when he was barely an adult and wrote the story of his life and how discrimination affected it. Not only is discrimination the theme of Douglass’ novel, it is also the cause of his horrible condition. In his autobiography he claims he “was made to drink the bitterest dregs of slavery'; (73). Throughout the novel Douglass never encounters a slave who is not black. “Why am I a slave,'; Douglass asks (Douglass 73). This is surely a question asked by every victim of prejudice. Another piece that illustrates discrimination is Joseph Brant’s, “Indian Civilization Vs. White Civilization.'; Joseph Brant was born in 1742 and died in 1807 (Barnett et al. 938). Brant, or Thayendanega, was educated at Wheelock’s Indian school in Connecticut. He served the British in the French and Indian war and the American Revolution. Being a Mohawk Chief, Brant was subject to much racially motivated discrimination. Discrimination, though most author would like you to believe otherwise, is never one sided. “ Indian Civilization Vs. White Civilization,'; looks at the reactions of those victimized by racial discrimination. Joseph Brant initially takes a defensive stand, but quickly turns to criticism of white society. In this piece Brant is “obliged to give [his] opinion in favor of [his] own people.'; (Brant 939). He describes the white people’s judicial system a pompous parade'; (Brant 939). In conclusion of this piece Brant never overcomes his bitterness for white people and their actions calling them “tenfold more the children of cruelty'; (Brant 939). In addition to this essay, Martin Luther King Jr.’s speech , “ I Have a Dream'; also contains the theme of discrimination.

Memasyarakatkan Alkitab atau meng(al)kitabkan masyarakat? :: essays research papers

Memasyarakatkan Alkitab atau meng(al)kitabkan masyarakat? Tantangan dan Kesempatan bagi metode BGA dalam konteks kelisanan dan keberaksaraan Makalah ini disajikan dalam salah satu sesi dalam pelatihan Tim Pelayanan Proyek Philadelphia (TP3) pada tanggal 26 Juli 2004, di Wisma Anugerah, Cisarua, Bogor. Pengantar Makalah ini merupakan bentuk konkretisasi dari refleksi saya berdasarkan berbagai pergumulan berteologi serta pengalaman melayani dalam pembinaan BGA serta berdasarkan karya sehari-hari sebagai anggota staf penerbitan Yayasan PPA. Sebelumnya saya pernah menyusun dan menyajikan beberapa renungan dan makalah yang telah saya sajikan dalam berbagai pertemuan internal PPA. Perkembangan serta perubahan pemikiran saya setelah saat-saat tersebut kini tertuang dalam makalah ini.   Ã‚  Ã‚  Ã‚  Ã‚  Melalui judul dari makalah ini, saya ingin menunjukkan bahwa masih ada beberapa kebijakan, pemikiran, dasar ideologis-teologis dll. yang berkaitan dengan metode BGA, yang masih perlu diperjelas. Judul dari makalah ini menyiratkan salah satu dari beberapa pilihan yang harus diambil: memasyarakatkan Alkitab atau justru meng(al)kitabkan masyarakat. Tujuan makalah ini adalah untuk mengajak kita memikirkan pertanyaan-pertanyaan seperti ini, serta pendapat saya tentang jawaban-jawabannya bagi pertanyaan-pertanyaan tersebut. Mencari udang di balik batu: Konteks keberaksaraan, kelisanan, dan kemajemukan media dalam gaya hidup orang Indonesia Ada banyak istilah yang digunakan orang untuk menjelaskan kemampuan seseorang untuk membaca dan menulis. Ada yang menggunakan istilah melek huruf, keaksaraan, keberaksaraan dll. Dalam makalah ini, saya akan menggunakan istilah  ¡Ã‚ ®keberaksaraan ¡Ã‚ ¯ untuk menunjuk kondisi masyarakat yang secara umum didasarkan pada kemampuan membaca dan menulis, dan  ¡Ã‚ ®melek huruf ¡Ã‚ ¯ untuk kondisi seseorang. Untuk kondisi seseorang yang tidak mampu membaca dan menulis saya menggunakan istilah  ¡Ã‚ ®buta huruf ¡Ã‚ ¯, sementara  ¡Ã‚ ®kelisanan ¡Ã‚ ¯ menunjuk kepada kondisi masyarakat yang lebih didominasi oleh ujaran verbal ketimbang teks tertulis. Saya juga ingin memperjelas makna dari satu istilah yang saya gunakan dalam makalah ini. Mengikuti definisi yang digunakan oleh UNESCO,  ¡Ã‚ ®buku ¡Ã‚ ¯ atau  ¡Ã‚ ®kitab ¡Ã‚ ¯ adalah bahan cetak yang terdiri dari 49 halaman atau lebih, tidak termasuk halaman sampulnya. Menurut Susenas/Statistik Pendidikan, proporsi penduduk buta huruf usia 10 tahun ke atas adalah sebagai berikut: Jenis Kelamin  Ã‚  Ã‚  Ã‚  Ã‚  Kota  Ã‚  Ã‚  Ã‚  Ã‚  Desa  Ã‚  Ã‚  Ã‚  Ã‚  Kota dan Desa Pria  Ã‚  Ã‚  Ã‚  Ã‚  3.76  Ã‚  Ã‚  Ã‚  Ã‚  10.32  Ã‚  Ã‚  Ã‚  Ã‚  7.52 Wanita  Ã‚  Ã‚  Ã‚  Ã‚  9.44  Ã‚  Ã‚  Ã‚  Ã‚  20.17  Ã‚  Ã‚  Ã‚  Ã‚  15.54 Pria dan Wanita  Ã‚  Ã‚  Ã‚  Ã‚  6.63  Ã‚  Ã‚  Ã‚  Ã‚  15.53  Ã‚  Ã‚  Ã‚  Ã‚  11.55 Beda Wanita Pria  Ã‚  Ã‚  Ã‚  Ã‚  5.68  Ã‚  Ã‚  Ã‚  Ã‚  9.85  Ã‚  Ã‚  Ã‚  Ã‚  8.02 Angka ini bisa kita bandingkan dengan tabel keberaksaraan penduduk dunia menurut wilayahnya yang ada di bawah ini. Secara sekilas, kelihatannya taraf keberaksaraan penduduk Indonesia, termasuk umat Kristen di dalamnya, telah mencapai angka yang cukup menggembirakan. Kita dapat mengandaikan bahwa penduduk Indonesia beragama Kristen (yang pada tahun 2000, demikian menurut LP3ES, berjumlah 17.954.977 jiwa atau 8,92% dari keseluruhan jumlah penduduk ) juga memiliki persentase keberaksaraan yang kurang lebih sama dengan komponen penduduk Indonesia lainnya. Bila angka-angka ini benar, maka kelihatannya tersedia ladang yang cukup besar bagi pelayanan pencetakan Alkitab serta literatur penyertanya (sekitar 15 juta jiwa orang Kristen yang dikategorikan tidak buta huruf).

A long way Gone and Refugee Boy

Ishmael Beah’s A Long Way Gone and Alem Kelo’s Refugee Boy are both exceptional books on the lives of two different people in two different countries undergoing almost similar events in life.Both of the stories portray life from the perspective of two vulnerable children caught up in circumstances that are not pleasant. However, the only difference between the two is that while Beah’s events are actual events, Alem Kelo’s are fictitious. However they both succeed in portraying the hard life of a child trying to fit in to a society that is alien to him.A Long Way Gone: memoirs of a boy soldier.Ishmael Beah, in his autobiography recounting the war years in his country, Sierra Leone, details how he became a child soldier. He says that when the war started, his mother and his father, who were from different tribe, which happened to be at war with each other, were separated. Though he does not give much detail as to how and why they separated, he records that t hey went separate ways.After the militia invaded their village, and he narrowly escaping being forcefully recruited into the militia, he realizes that there is no other way to escape the war and its only a matter of time before he either join the army or the rebel forces. So he opts to join the army citing the reason that in doing so he could atleast avenges his relatives who were killed by the rebel forces.In the army he also survived by taking ‘brown brown’, a mixture of gun powder and cocaine. This he says they were influenced to take due to the various brutal and sometimes vicious they had to do.The story is quite remarkable in that Ishmael Beah tends to remember almost all the little tiny details, which are remarkable, considered that most of the things he went through were quite early in life. For example he can vividly recount the events that marked the beginning of civil war in their village; he can remember the details like a woman carrying a bullet ridden chil d, a Volkswagen that brought the first people to be affected by the war and so on.Refugee Boy:Refugee boy is a fictional book by Benjamin Zephaniah. It tell the life of a young boy from a mixed family, the father being an Ethiopian while the mother is an Eritrean, it happens that these two countries are at war and Ethiopian army is demanding that foreigners, especially from Eritrea to leave the country.In the story, Kelo, being of mixed blood, cannot be accepted in either Ethiopia or Eritrea. The soldiers who come to compel them to leave call him â€Å"a mongrel†. So in search for safety for their son, Kelo’s father takes him to London in what to Kelo seemed like a holiday. Kilo is however rudely shocked when he realizes that the holiday was not really a holiday after he is abandon in a hotel room by his father.His predicaments are just beginning since he has to move to children’s home then to a foster home at the Fitzgeralds. In between he fights to get asylum in UK. He is tossed in the hands of social services and the Refugee Council of England.ReferencesZephaniah, B. (2004). Refugee Boy.
