The Heckscher-Ohlin Essay Example for Free

The Heckscher-Ohlin Essay The Heckscher-Ohlin theorem of international trade argues that a capital abundant country is supposed to export those goods that are capital intensive while a country that is labor abundant is expected to export goods that are labor intensive, while David Ricardo argued that there should be free trade among countries and also there should be specialization among the individuals in production of any products. Ricardo later assumes that there is mutual benefit in trade between two countries even if one country has the resources while the other lacks the resources. The Heckscher-Ohlin theory assumes that the two countries in trade are identical apart from the differences in their resource endowments. The abundance in capital results in the capital abundant country producing the capital intensive good (Ethier, 1974. ) When there is specialization and trade between two countries there will be an improvement in the standards of living in the two countries. The Leontief paradox argues that trade is normally determined by the level of abundance of the factors of production in any economy. He found that although the USA was well endowed with capital it exported labor intensive products and imported capital intensive products. International trade is determined by endowment factors in any Nation. Those countries which have endowment factors for the manufacturers will trade with each other while countries with favorable factors for production of primary products will trade with each other. A specific tariff is a fixed rate that is charged on a certain predetermined quantity for example$10 per Kilogram. An ad valorem tariff is a fixed percentage of the total value of the goods being imported. A compound tariff is a charge on a good comprising of both the specific tariff and the Ad Valorem Tariff.

Review of Copper Recovery Methods From Metallurgical Waste

Review of Copper Recovery Methods From Metallurgical Waste Apurva Patel, Prof. Nimish Shah Abstract: Copper is one of the most used metals in recent developments and demand of this red metal is increasing with passing of each day. Production of copper is 12 million tons per year and copper reserves are expected to run for 25 years with the estimated world copper reserves of 300 million tons. Recovery of copper from metallurgical waste is a trend that is being followed from beginning of industrial age and has many developments over a large time frame. Out of all the copper used in existing process, 2 million tons of copper is utilized with recycling of copper waste. India has limited copper ore reserve contributing about 2 percent of world reserves. We can say that copper has a large amount at our reserves but excavation is not as simple as it seems. Copper content in the raw mines is ranging from 0.5 to 1 percent. Even after recovery of copper there is large waste generated at the end of the process. Copper content in the waste is up to 0.3 percent at the discharge. Ultima tely around hundred times of waste is generated for recovery of one part of copper. That pushes forward the need of recycling copper from metallurgical waste to cater the need of increasing copper demand. Copper recovery from high copper containing metallurgical wastes like brass industries are generally dealt with smelting process. In such case large amount of energy is utilized to just melt down all the material. This process has a limitation of copper content i.e. if copper content is low then all the energy is utilized in melting of undesired material. Demand for electroplating of copper has increased significantly. Low efficiency or improper process handling causes remarkably high copper content in waste discharge, which is over the range of discharge criteria of heavy metals. So to control the increasing price of metals and to limit the use of fresh copper, recycling must be done so the recovery from waste also gives the advantage of being in range of the allowable government legislations. Though these hazardous heavy metals in electroplating waste having concentration high enough to give harmful impacts to environment but convincingly low concentration that is not enough to recover these metals effectively. In this paper, an overview of different methods for copper recovery is illustrated and justified the selection of different methods over different copper content of various sources. Keywords— Copper extraction, Copper recovery, Electroplating, Recycling, I. INTRODUCTION Increasing demand of copper gives elevated chances for generating copper waste from different industries. There are thousands number of industries existing which includes utilization or processing of copper. In this paper, review of several most copper containing waste and most optimum copper recovery methods are described. Waste source is targeted which gives better possibilities of copper recovery and ease of operation. Several metallurgical source like; bronze scrap, copper converter slag, electroplating waste, and pickling solution is included in the study. II. Different copper source and recovery methods Recovery from copper slag There are different verities of slag produced from smelters for non-ferrous production. Major emphasis is given to copper slag as it has equal to or higher copper content compared to raw copper ore. Generation and utilization of copper slag has higher environment impacts compared to steel and iron slag as they contain remarkable quantity of heavy metals with higher solubility. Chemical composition of copper slag varies with different origins. Chemical composition is given as per work of Shen Forssberg in table 1. TABLE I Chemical composition of copper slag Elements (Percentage) Cu 0.6-3.2 Fe 32.7-37.3 SiO2 32.5-37.3 Al2O3 2.4-4.0 CaO 1.8-7.5 MgO 1.6-4.0 S 0.5-1.0 There are specific three methods to recover copper from copper slag; Floatation, Leaching and Roasting Floatation: Barnes has given industrial floatation process at Mount Isa Mines Limited to recover copper from copper slag. Grinding operation is applied until obtain the granular size of 80%- 74  µm before floatation. Floatation is also feasible for magnetite present in the raw copper slag, so hydroxy ethyl cellulose is used in the process as a depressant of magnetite impurities. MIBC is used in the process as froather agent and sodium sec-butyl xanthate is used as a collector of copper from the waste. The result of this process gives concentrate grade copper with high percentage as 42.54%. Overall yield of such process is 82%. This experiment is observed for copper slag containing 3.7% copper. In this experiment most of Co is observed with floatation tail. Mainly, copper slag floatation is somewhat similar with sulfide ore floatation because of the fact that only metallic copper and sulfide minerals from the copper slag can only be effectively floated. In other slag copper is usually observed under oxide state and Co and Ni are also in oxide state because of its homogeneous distribution in the slag. So the stated method will not be utilized effectively with Co, Ni and oxide copper state. Therefore the span for the floatation process is reduced in size as less quantity of Co, Ni must be present in the slag or copper must not be in the form of oxide. Leaching: Basire and Anand described leaching thoroughly about its use and study over some leachants mainly hydrochloric acid, ferric chloride, ammonia, and sulfuric acid. In the initial era cyanide was also used but it was terminated because of its harmful effects to environment. Leaching is positively influenced by addition of H2O2, or leaching with Cl2/Cl system, or pressure leaching. Figure 1 shows effect of H2O2 on leaching of copper based on the experiments of Base metal recovery. Figure 1. Kinetics of copper recovery Graph showing metal recovery with highly oxidising agent like H2SO4 for copper slag. Experiment is carried out with 10% solid in solution and particle size less than 100  µm. Experiment is carried out at 70 oC and pH maintained at 2.5 with applied H2O2 at 35 L/(h.t) Pressure leaching has broadly described by Anand, shows that with pressure leaching and use of dilute H2SO4 recovery of copper about 90% achieved from copper converter slag from the initial concentration of 4.03% Cu. Roasting: Roasting is actually one intermediate step which involves the process for converting the copper in desired form that can be easily separated from the raw material. After application of roasting, Leaching or floatation must be used to achieve desired separation. If we narrow down the process criteria then we can say a lot more specific term as sulfate roasting instead of roasting. In this process conversion of cupper cobalt ant nickel is taking place and transformed into more feasible soluble sulfates. Raw material is processed at 200-600 oC by addition of sulfide or sulfate agents. Then these soluble sulfates are dissolved in water and easily separated from slag. Some of the agents used in the process are, (NH3)SO4, H2SO4, H2S, pyrite etc. Sulfurization reactions are summarized as bellow. Cu2O + H2S à ¯Ã†â€™Ã‚ ³ Cu2S + H2O †¦(1) 2Cu + H2S +  ½ O2 à ¯Ã†â€™Ã‚ ³ Cu2S + H2O †¦(2) Sulfides of copper are then easily converted to soluble copper sulfate with roasting at 600oC. Ziyadanogullari used this method to treat copper slag containing 2.4% copper. By sulfurization in closed system with 140oC for 1 hour and then heating and roasting with 600oC for 360 minutes gives better result for recovery of copper up to 99.2%. Copper recovery from bronze scrap Bronze is the mixture of copper, lead and tin. Vast numbers of studies are going on as well as succeeded for recovering copper from brass scrap. Ludovicus produced black copper by reducing scrap at 1300oC after melting at 1180oC. After recovery of black copper oxygen gas is supplied in ample amount with a view to oxidize all metal impurities and obtained anode grade copper. Morsi and Rabah have studied different parameters for recovery of copper by melting the bronze scrap. They obtained bronze scrap which comprise of chips, turnings and pieces ranging from 1-5 mm in size from El-Maady Co. for Engineering Industries, Cairo, Egypt. Experimental work uses a computerized heating mechanism with silicon carbide-heated muffle furnace. With operating temperature of 1600oC slag generated contains tin and lead that is continuously skimmed off with a view to eliminate the possibility of joining the slag to molten copper. Slag generated from the process also has small copper content which is re covered by acid leaching to increase overall yield. Experiment is carried out by Morasi and Rabah at different temperatures and copper content with overall yield is measured at 15 and 30 minutes. Figure 2 Effect of temperature on obtained copper alloy Figure 2 enlightens the behavior of copper residue and composition of the same. Experiment is carried out at 1150oC, 1200oC, 1250oC and 1300oC and at time interval of 15 and 30 minutes. As we can see with increasing time recovery is increased but behavior of recovery is same. Overall yield is decreased with increasing time because more amount of metal is being dragged with slag formation. Removal of lead and tin from slag is favored by addition of copper sulfide with provision of air which convert impurities into sulfides and pushes forward the percentage amount of impurities into slag and increased recovery of copper in residue. Addition of 10-20 percent copper sulfide reduces up to 10 percent lead and 8 percent tin in copper residue. Recovery of copper is 96.2% with combination of acid leaching from the generated slag. Recovery of copper from pickling solution. Like every common metal, brass also has a tendency to corrode. Corrosion of brass takes place by contacting the outer surface to air. Corrosion of brass looks like black coating on the outer surface and it is called tarnish. This coating in non beneficial in any condition so it must be removed. Removal of corrosion includes dipping brass metal in dilute sulfuric acid solution, which is used for a long time before it finds its way to discharge. This utilization over a long period of time enriches the dilute solution with valuable metals such as copper, zinc, chromium etc. This heavy metal enriched mild acid solution is called waste pickle solution. Because of its environmental hazards it cannot be disposed off without removing toxicity. Recovery of copper is a coincidence that will make disposal waste under legislative limits and will provide economical benefit by recovering valuable metals. Pickling solution has a base of mild sulfuric acid and has the highest percentage around 45.1 g/L of H2SO4 in the same. It has around 25 g/L Zn and 35 g/L Cu(II), and other negligible impurities like chromium, iron and nickel. First using equal volume of TEHA (tri (2-ethylhexyl) amine) extractor acid is being removed with formation of immiscible layer over organic layer and can be easily removed from the mixture. Copper and zinc may be present in the sulfate form as no part of any metal is observed in the extracted acid and TEHA has less affinity towards sulfates of copper and zinc. This acid free pickle liquor is used with other extractors like Versatic 10 acid and Cyanex 272[bis-(2,4,4-trimethylpentyl)-phosphinic acid] for recovery of copper and zinc. Kerosene is used as diluents in the solvent extraction. pH of Versatic 10 acid and Cyanex 272 is having higher influence on extraction. Increasing Ph resulting in increment of metal extraction and at 5 pH and 30% Versatic acid concent ration all the copper is extracted. Whereas, zinc extraction is observed above pH 5 and is completely extracted in organic phase at pH 7.0. III. Copper recovery with electroplating With a specific type of waste that has copper in isolated pure form this technique can be used. A new idea is generated for separation of copper from waste like alloy waste brass industries waste, electrical waste etc. Tank is filled with electrolyte like zonax, copper sulfate etc. The idea is to provide continuous separation from raw material and to facilitate collection of nearly 100 percent pure copper. New type of vessel needs to be developed which has stainless steel base that can be acting like cathode and a receiver anode needs to be in center of tank. Outside walls must be made up of insulating material or at-least needs to have insulation over the wall to isolate human contact by accident during the process. Figure 3 electroplating for copper recovery Figure is showing the possible assembly of electroplating mechanism for semi continuous copper recovery. Copper in the raw material comes with contact of electric field applied across the length of the assembly. Copper in the electrolytic solution first separated and settled on anode. By this, copper-ion deficiency is generated in the solution. To mitigate the deficiency, copper from the raw material comes in to electrolytic solution and completes the chain reaction. Pure copper sulfate and zonax solutions are not conductors of electricity. For ease of operation pure water needs to be added to convert ions from the solution. Because of water addition now electrolytic solution has H+ ions and by getting enough electricity they will convert into hydrogen gas and applied electricity cannot be used efficiently. This apparatus can be operated within range of 2-12V. Above this range H2 will start to consume additional energy. Higher the applied amperes better the rate of deposition of copper from the raw material. Rate of deposition can be calculated by equation given by Michal faraday, i.e. W=(I.T.A)/(Z.F) where, W is the weight of copper deposited, I is the amount of current applied (amp), T is the amount of time for which current supplied, A is the atomic weight of substance, Z is vacancy and F is faraday constant 96,500 coulombs. For selection of electrolyte free electrons play vital role. General electrolyte as copper sulfate has higher efficiency for electroplating then zonax, but zonax is mono-valance electrolyte and less electricity is utilized for almost double copper extraction compared to copper sulfate. IV. Conclusion For efficient recovery of copper from various source first type of source and form in which copper is present must be determined. Floatation is not the most accurate and efficient method for separation of copper but it is widely used for primary separation of copper and for concentrating the raw copper for other applicable process like smelting. Leaching of copper is the most widely used and efficient copper removal process but it must be followed by electroplating of iron addition process to obtain pure copper. Some parameters like pH and temperature of leachant must be observed and needs to be carefully maintained. Roasting is also a two step process in which copper is converted to more feasible sulfate form and can be easily extracted by leaching. Bronze scrap has more copper content in the structure and needs to be carefully processed to obtain large number of copper content recovery up to 96% and other recovery by leaching from slag generated can increase the overall yield. Anot her phenomenon has been studied for pickling solution which has serious pollution problem at the disposal and economic problem at treatment. For treatment acid must be removed in the pretreatment and then copper along with valuable metals can be efficiently recovered with Versatic 10 acid. In the end new method has been observed for semi continuous operation for copper recovery using specific electrolyte and modified operation tank.

Service Quality Analysis of Mental Care Employees

Service Quality Analysis of Mental Care Employees The gap between professionals and client was one of the central elements of our study. The perceptual gap between providers and clients is often studied in order to measure and analyses service quality (Brown Swartz, 1989; Klose Finkle, 1995; Luk Layton, 2002; Peiro et.al. 2005; Zeithaml et.al. 1990). Our findings that clients are tend to overestimate service quality is different from the findings by Peirà ³ and colleagues (2005), which have shown that employees are tend to overestimate service quality they are offering in a context of hotels and restaurants. Here we can suggest that service quality gaps characteristics (overestimation vs underestimation) much depends on type of service provided by the organizations. According to this comparison we assume that professionals working with PIDs have more vulnerable ethical issues in service, in other words empathy can be on higher position which itself can affect the way the service is provided by the professionals to the benefit of the client’s demands. People who are in charge to help and assist persons with intellectual disabilities with nearly every level of need, including physical, counseling, and education can be already considered as stress related. And ethical issues are deep rooted in the professional role (Raines, 2000). Employees facing ethical dilemmas in service often have mental conflict offering service as they are trained, or offering the service as clients (relatives) are asking, or demanding: what is good (virtue) or what is duty (right)? (Aroskar et.al., 1997). Our results confirm this divergence showing that there is less congruence in service quality evaluation from the clients and employees. Overestimation from clients’ represents that service is provided the way they prefer, which itself is connected to professionals’ decision – to adjust service to clients’ needs and demands. On other hand in case of professionals overestimation of service quality we have decreased clients’ satisfaction which, continuing the same logic is result of that they have different approach to the kind of service PIDs need. In this case when employees prefer to conduct service they consider is right contradicts to the service evaluated by clients, finally it leads to client underestimation and causes low level of satisfaction. These findings are similar to the study results by Emari and colleagues (2011) which tested that causal relationship is significant between perceived quality of service and client satisfaction. According to our study overestimation from employees not only connected to low client satisfaction but also decreased quality of life of users. Results reported that higher is the evaluation of service from professionals lower is the quality of life of persons with intellectual disabilities. In other words when employees perceive that service provided by them is good, relatives think that this service decreases quality of life of PIDs. Here we have to recall that these organizations are designed to care the QoL of individuals with intellectual disabilities (Martinez-Tur, Peiro, Moliner, Potocnik, 2010). And these organizations are important source of QoL for people with intellectual disabilities (Moliner, Gracia, Lorente, Martinez-Tur, 2013). Situation is quite complex, when service quality is perceived differently by clients and employees. Non-congruence and different views between them about service quality impacts organizational facets and goals; if we have satisfied clients we have emotionally exhausted professionals, and on the other hand we have lower client satisfaction and lower quality of life of PIDs. Here moderation roles are important to dilute these relationships. The moderators tested in our study have less to contribute to weaken the above mentioned relationships. Moreover, high supervisor trust can be related to increasing sense of responsibility from employees; similar to study findings conducted with social workers which reported that emotional exhaustion is significantly related to good performance (Wright Cropanzano, 1998). According to our study justice perceived by relatives has no influence on the relationship between service quality gap effects on their satisfaction. Despite of the fact that organizational justice doesn’t revealed moderation effect on gap impacts, it has direct effect on client satisfaction; results reported that they are significantly related. Also quality of service perceived by PIDs doesn’t have moder ation role on relationship of service quality gap and their quality of life. Our study shows that at Mental Care organizations employees are tend to underestimate the service quality they offer. Additionally, when employees’ overestimation is higher for service quality, clients are less satisfied with the organization. In line with previous studies (Brown and Swartz, 1989; Klose and Finkle, 1995, Peiro, Martinez-Tur, Ramos 2005), a shared vision between employees and customers is required. If the delivery of services is overestimated from professionals, the client satisfaction and their service evaluations suffer. If the service is overestimated from clients we have employees’ emotional exhaustion. Although gaps between employee and clients’ perceptions involve different alternatives (overestimation, congruence and underestimation), the predominant situation in our study involves employee underestimation. A principal theoretical contribution of this study is the incorporation of service relational benefits to gap analyses, in order to cl arify their role in predicting employees’ well-being, client satisfaction and quality of life of PIDs. The data also presented interesting observation that high supervisor trust may have undesirable impact on employees’ mental health. The findings presented above indicate that the distinction between clients and employees’ gaps is an important theoretical issue. Considering the integral role that work plays in the well-being of people s (e.g., Kahn Byosiere, 1992) and peoples well-being plays the important role for organization, e.g. turnover (Wright Cropanzano, 1998), managers must be prepared to address and utilize interventions related to the type of service is provided by their employees. Organizations must focus more attention to bring in agreement perceptions of high quality service. Also it is important to increase the organizational experience of listening to clients and do monitoring of how far are disagreement in service quality evaluation. Also there is a need for effective and continuous training programs for the employees who work at centers of intellectual disabilities to learn how to cope with emotionally demanding communications with clients. In addition, supervisors should be trained to learn how to provide assistance for front-line employees to reduce emotional exhaustion. With particular focus on potential barriers organ izations can overcome the problems related to divergence in perceptions and related to it issues. The findings have several implications for future research related to the limitations of this study. Given that the samples in this study were restricted to mental care service centers, these type organizations are different from ordinary service organizations since this is a case when service users are less able to assess and evaluate service quality; and it is evaluated by their relatives (non-direct users of service). According to this argument the findings can’t be generalized and the present hypotheses need to be replicated in other service organizations. Also Future effort in this direction could contribute to a better understanding of service gap differences in terms of functional and relational dimensions, and how far differently they impact on organizations, clients, and employees. Also it’s important to continue research in direction of factors which can moderate the service quality gap effects. One of the suggestions can be quality of life of persons with disabilities can moderate gap impact on clients’ satisfaction. Improving the life of PIDs can affect clients’ satisfaction level despite of the incongruence on service quality perceptions. Also we have to have in mind that in presented study service quality, organizational justice and quality of life all were evaluated from clients; we can consider that this is one of the limitations of the study. Future studies would be beneficial to collect data from multiple sources to minimize the potential threats. Supervisor trust role in emotional exhaustion also needs further investigation from different perspective; according to research conducted by Moliner1, Martà ­nez-Tur, Peirà ³, Ramos and Cropanzano (2013) lowest levels of burnout of employees were observed in situations of perceived ove r-benefitted reciprocity in their relations with supervisors; also study conducted with hotel employees found that perceived organizational support can significantly impact on employees’ emotions (Karatepe, 2011). Having in mind that organizations and employees differ in the degree and the way to which they are perceive shared systems, structures and rules affecting their behavior (Greenwood Hinings, 1996; Peirà ³ Martà ­nez-Tur, 2008) we assume that future research can benefit to investigate the role of supervisor trust perceived by the employees. Also there is suggestion about time: since the service is no single time activity and it is continuous in time, service quality evaluation can be repeated over time, the impact of service quality gaps on organization facets could be followed at different temporal moments. Presented study described service quality gaps and problems derived from them, evaluated by professionals and clients of Mental Care Centers. Study showed the disagreement in service quality perception among clients and employees. Employees’ experienced emotional exhaustion in situations of overestimation of service quality form employees. Service quality overestimation form employees occurred harmful for organizational satisfaction and also decreased the level of quality of life of PIDs. The findings in this study suggest some theoretical and organizational implications, as well as suggestion for future researches. Endless improvement in ethics is anticipated to be an integral and routine part of the job of everyone in mental care area. The results of our research can be also used to improve structural aspects of mental care service organizations.

The LASIK Surgical Procedure :: Research Papers Essays

The LASIK Surgical Procedure LASIK is a surgical procedure done on the eyes so that people can see ok better. One would not have to wear contacts or glasses anymore. According to the U.S. Food and Drug Administration, LASIK is a surgical procedure done to reduce the use of glasses and contacts. However doctors say that if one is comfortable wearing their contacts and glasses then they should continue doing so. Why is that? There are many risks and complications with the procedure that one must weigh out before going through with it. Before I go into detail what the risks are let me explain in detail what LASIK is. LASIK stands for Laser-Assisted In Situ Keratomileusis. It is a surgical procedure that involves permanently changing the shape of one’s cornea, which is the clear covering of the eye, using an excimer laser. The procedure calls for cutting a flap in the cornea to reveal the stroma, second layer of the cornea. A laser is used to vaporize the stroma and then the corneal flap is replaced. Sounds easy, right, however, there are many complications and stipulations that go along with this procedure. LASIK is primarily for those who are myopic (nearsighted). Those who have astigmatism (blurred vision due to an irregular shaped cornea) and are hyperopic (farsighted) are still capable of getting the procedure but have to take a greater risk. The ideal individual, according to the Eye Surgery Education Council, for LASIK is one who is eighteen years of age, has sufficient corneal thickness, does not suffer from any disease that may hinder their ability to heal correctly and, one who is either myopic, hyperopic, and/or has astigmatism. The less ideal individual is one who has a history of dry eye, takes medications such as steroids or immunosuppressants and/or has corneal scarring.

Making False Confessions Essay -- Psychology, Learning Disabilities, M

Psychological research and application have established that it is not only people with learning disability or major mental illness that are susceptible to make false confessions. In order for a confession to be false, a person must either confess to a crime that he or she is completely innocent of or overstate his or her involvement in the crime. False confessions can be either voluntary or coerced. Although it is methodologically difficult to establish the frequency of false confessions, anecdotal evidence such as self-reports and case studies indicate that reported cases are only the ‘tip of the iceberg’. It appears that young people are particularly vulnerable and often make false confessions in order to protect others. Standardized psychological tests have been devised in order to assess personality factors such as suggestibility and compliance that render some people more vulnerable than others. The reason people make false confessions is typically due to a combina tion of factors such as psychological vulnerabilities, nature of the custodial confinement and the police interviewing tactics. Notorious cases of false confessions which have lead to the wrongful convictions of innocent people subsequently spending years in prison represent some of the worst cases of miscarriage of justice in Britain. One such cases, that of Engin Raghip of the so-called ‘Tottenham three’ will be discussed in the context of admissibility of psychological evidence in order to demonstrate how the judiciary has increasingly come to accept the psychological notion that most people, under certain circumstances, are susceptible to making false confessions.

General Haig

Did General Haig Deserve To Be The Butcher of the Somme In June 1914 a Serb assassinated Franz Ferdinand, the heir to the throne of the Austrian Empire. Austria decided to take revenge against Serbia and invaded. However, Serbia had an alliance with Russia, and Russia with France. Germany came to the aid of Austria. One by one, the powers of Europe were pulled into war by their alliances. This source is taken from a book called â€Å"Investing History a World Study By 1916†. The French were fighting at Verdun for 2 years in trench warfare and no one was winning.The French were on the brink of defeat so they asked the British could they attack on the Somme Valley to give the French some breathing space. The British bombarded the German trenches for 7 days non-stop. Over 3 million shells hit the German trenches. However the Germans built underground bunkers made out of concrete. On July 1st 1916 the first waves of the British soldiers went over the top and were ordered to walk t o the German trenches at walking pace thinking that all of the Germans were dead when the bombardment stoped however then the Germans came out of the bunkers and shot the British down with machine guns.On the first day of the battle 20,000 British soldiers were killed and 30,000 soldiers were injured or wounded. Sir General Haig was in charge of the British at the time. People think that Haig should be remembered as the â€Å"butcher of the Somme† because he sent thousands of British soldiers to their deaths. Some people thought that Haig was a donkey leading lions. Over 1 million men volunteered to fight in 1914 thinking it would be over by Christmas but the battle of the Somme kept going until November 1916 the battle lasted five months. By the time the battle ended 420,000 British soldiers were dead.It was the biggest British military disaster in British history, based on British and German first hand accounts on the battle. The other interpretation of Haig is that he was just doing his job because he was just sending men as he was ordered to do. Source 1A is a valid source to find out the truth about General Haig because a private Fred Pearson on the Western Front, was commented On Haig in a local newspaper in 1966 and he said â€Å"The biggest murderer in the Somme of the lot was Haig I’m very bitter; always have been and always will be and everybody else that knew him.He lived 50 kilometres behind the line and that’s about as near as he got. I don’t think he knew what a trench life was like and they made him an earl and gave him ? 100,000. I know what I’d given him. I think this is reliable because the person who wrote this source is that he was there on the western front and he experienced what the war was like and what Haig was doing. Source 1B and source 2 is good to find out the fact that General Haig was a butcher of the Somme. P. Smith, a private in the 1st border regiment fighting on the Somme, writing in his di ary July 1916.Said, â€Å"It was pure bloody murder. Douglas Haig should have been hung drawn and quartered for what he did on the Somme. What this means is that Haig sent Millions of the young generation to their deaths and no one had really to replace them in their villages or towns. The cream of British manhood was shattered in less than six hours. This is reliable and useful because Private P. Smith was actually there at the battle of the Somme and he saw thousands of friends, family, killed and he foresaw Haig’s doing. Haig was a second-rate commander in a unparalleled and unforeseen circumstances. He was not endowed with any of the elements of imagination and vision and he certainly had none of that personal magnetism which has enabled great leaders of men to inspire multitudes with courage, faith and a spirit of sacrifice he was incapable of planning vast campaigns on the scale demanded on so immense a battle†. This was written by David Lloyd George, British Pri me Minster during the First World War, writing in his War Memoirs (1935). This is reliable becauseSource 6 is valid information about finding the truth about Haig because it’s a cartoon and in it the major general is addressing the men before an attack behind the lines. â€Å" I want you to understand that there is a difference between a rehearsal and the real thing. There are three essential differences: first, the absence of the enemy. Now turning to the Regimental Sergeant- Major what is the second difference? † Sergeant Major. † The absence of the General, Sir. † This source was written in a cartoon to make fun out of the generals as seen in the cartoon. It was written in (February 1917) a cartoon from the British satirical magazine punch.Source 7 is a good evidence to find out the truth about Haig because in this source Blackadder is trying to change General Haig’s mind about going over the top but Haig doesn’t change his mind. [This is t aken from the BBC TV comedy series, Blackadder, which continually portrayed Haig and the generals as fools and murders. In this scene Blackadder is trying to persuade Haig to get him sent home while Haig plays games with toy British soldiers. The series was broadcast in the 1990s. ] I’ am now going to look at source 8 in this source John Laffin writing in his history book

Reproductive Health Bill Philippines Essay

When I hear the RH Bill, What comes to my mind? I must say that I am in favor to this law in the Philippines . This law means having control of the growing population in the Philipines and this will lessen poverty due to the lesser family members. The law states that the people has choices to pick in starting a family like contraceptives, condoms, pills, IUD. This Bill will help people much especially the uneducated ones to know more information about family planning, prevention of abortion, sex education, prevention of HIV/AIDS and others. The poorest family may have the biggest family, now is the time for them to give education about controlling by approving this bill. I think this bill was aimed to the poor ones because they are the ones who cannot support their family and most of them has no education, this means more problem. This helps us to make the lives of the filipino future to be more productive. We are already in a modern world, many of the people know about sex. Even out of wed lock have sex, even friends have sex but the bill helps to control having birth and being safe. Most especially teens, they are the one mostly who are engaging in sex. By giving them proper explanation by their parents to be responsible and do what is right, do you think that their children will listen? Well, it’s up to them but parents should always be reminding their children to do what is wrong from right. Why do others are against it? Maybe because it’s also against the Roman Catholic Church and the beliefs of other groups. But people has their own right what they will do and what they want to believe and use.
