IMPLEMENTING CHANGE IN HEALTH CARE (UK) - Essay Example How easy is it for people to give up their belief in their own competence Sometimes the need for learning new skills is recognised formally by an organisation when it builds training events into the change programme. Change affects people in different ways, but management experts tend to agree that people go through similar stages in order to come to terms with change. From this transition from resistance to acceptance of change to move into the desired future situation would depend mainly on tow factors, available resources and the willingness to change. Some theories cane be of help to assess this. Lewin's (1951) model of change is one of the most frequently used and easily understood approaches to planning and implementing change in organizations. Many people have added their own elaborations to this model, but its basic ideas remain the same. The basic elements of Lewin's change model are unfreezing, change, and refreezing. Assuming that a work situation is basically stable before change is introduced, although some changes occur naturally, people tend to stay in the "comfort zone" meaning they are generally accustomed to each other, have a routine for doing their work, and are pretty confident that they know what to expect and how to deal with whatever problems may arise in the course of a day (Lewin, 1951, 1-23). A change of any magnitude is likely to move people out of this comfort zone into discomfort. Lewin calls this movement unfreezing. People resist change for a variety of reasons, which vary from person to person and situation to situation. Some are ready to risk ch ange, and others seem to prefer maintaining the status quo. One change in routine provokes a storm of protest, whereas another change is hardly noticed. Resistance to change comes from three major sources: technical concerns, psychosocial needs, and threats to a person's position and power (Lewin, 1951, 35-41). Lewin suggested a way of looking at the overall process of making changes. He proposed that organizational changes have three steps. The first step involves unfreezing the current state of affairs. This means defining the current state, surfacing the driving and resisting forces and picturing a desired end-state. The second is about moving to a new state through participation and involvement (Lewin, 1951, 45-53). The third focuses on refreezing and stabilizing the new state of affairs by setting policy, rewarding success and establishing new standards. Lewin's three-step model uses the organism metaphor of organizations, which includes the notion of homeostasis. This is the tendency of an organization to maintain its equilibrium in response to disrupting changes. This means that any organization has a natural tendency to adjust itself back to its original steady state (Lewin, 1951, 57-78). Lewin argued that a new state of equilibrium has to be intentionally moved towards, and then st rongly established, so that a change will persist. Lewin's model was designed to enable a process consultant to take a group of people through the unfreeze, move, and refreeze stages. For example, if a team of people began to see the need to radically alter their recruitment process, the consultant would work with the team to surface the issues, move to the desired new state and reinforce that new state (Lewin, 1951, 85-99). Lewin's ideas provide a useful tool for those considering organizational ch

Code of Ethics and Safety in Engineering

Code of Ethics and Safety in Engineering Abstract With a safe product, we have no worries of using it because there is no risk that going to occur. But we must know that nothing in this world is perfect. Any accident can happen to any one of us out there. Engineer always involve themselves with design and creation of new things which demand for a good quality and safer product. Safe Design must comply with the applicable law, requires knowledge and capability, must attempt to foresee potential misuses of the product, must meet standard of accepted engineering practice and must verify every final design. After the process that being followed by the engineer themselves, so it is up to the user to use it in the right way. This project is expected to give awareness to the engineering ethic course student on the term risk, safety and accident in the real world. INTRODUCTION What can we say about Engineering Code of Ethics in this topic? To be simple, it is related to the engineers to produce products that are safe for the society. It is also important that they are the main role in preventing accidents of their invention. We must know that nothing can be 100% safe and perfect, but still engineers are required to make products as safe as reasonably possible.[1] Firstly, we must know that safety is about freedom from the occurrence or risk of injury, danger or loss. So, engineers have to follow the process or designing his product in order to make it safe as possible. Safe design is a process of hazard identification mainly at the design stage or controlling risk as early as possible to health and safety in the planning and design of products, systems or process. Through risk assessment, design option will be generated to eliminate Occupational Health Safety (OHS) hazards or to minimize OHS risks of injury to those who make the product and to those who used it.[3] In response to societal demands for safer products and workplaces, governments, businesses, engineers and others who are involved in innovation are requiring that safety be a fundamental principle in design. Design is a fundamental engineering activity. Engineer always involve in design, development and creation of new or improved products, process, systems and services. Hence, quality and safety in design should be fundamental in engineering concerns, not only to ensure that the code of engineering ethic is to be practiced but also to maintain a good reputation in engineering profession for better sense to develop products, processes and systems.[3] Safe design plays a big role in design objective, including practicability, cost and the functionality of the designed-product. Safe design is the process of successfully achieving a balance of these objectives. To ensure a total safety in a design, safe design needs an understanding of the each stage in the life of a designed product, starting with the initial conception to the end life of the product. Poor design can result in low productivity, higher maintenance, higher employment and workers compensation expenses and reduced asset life. These economic costs are in addition to human costs of injury, illness, disease and disability.[3] As we all know that accidents can always occur in anytime. It is usually happened on the user itself although the product that being used is already being design in term of safety and the usage too. It is case to case basis situation. It depends on whom to be blame. It may seem that engineers sometime bear no responsibility for any accident that happened. However, engineer must understand that the system or products that he is working on and to attempt to be creative in determining how things can be designed to avert as many mistakes by people using the technology as possible.[1] As we design something, we must also consider the manual and procedure for the use of the device or technology of the design. It is for the user itself. Engineers have to follow the design rules and in fact they have to pay the risk by designing something so that any accident can be averted. By generating the owners manual, maybe the user can use the device or the technology in the right way and it also can reduce the chances of getting any accident that can lead to death or injury. So engineers are born to help the people in the world by inventing the advance technology and designing it with the prospect of safety too. SAFE DESIGN CRITERIAS 1) Safe Design must comply with the applicable law All the design must meet their specifications and standards to ensure a good and safe design. Federal safety laws are different for each departments or industries. For example, International Maritime Organization (IMO) has an important part to play for adopting legislation for ships. IMOs safety legislation deals with the ship and passenger while The SOLAS (Safety of Life at Sea) do concern with passenger safety and with lifesaving equipment on passenger ships. While for electrical field, The National Electrical Safety Code (NESC) is a set of rules to safeguard people during the installation, operation, and maintenance of electric power lines. The NESC contains the basic provisions considered necessary for the safety of employees and the public. Although it is not intended as a design specification, its provisions establish minimum design requirements. PPL Electric Utilities Corp. (PPL) has developed design specifications and safety rules which meet or surpass all requirements specif ied by the NESC.[3] 2) Safe Design requires knowledge and capability In this case, engineers need to have and be able to demonstrate required knowledge about the design that he or she is about to build. They must have knowledge about the workplace hazards and any harmful effect because some of the design or project involves the prevention that may have potential to release hazardous material or energy. Such incidents will affect the environment such as toxic effects, fire or explosion and will drive to other consequences such as serious injuries, property damage and loss production. These are the basis possibilities that engineers must concern and implement ways to avoid any danger causes.[4] 3) Safe Design must attempt to foresee potential misuses of the product Engineers are professionally responsible for ensuring that their products or system are safe enough before they are established. They are legally bounded through law and regulations to ensure that their designs are safe from concept through disposal. To ensure a safe design, engineers must foresee the possibilities about the misuses of the products and implement ways to minimize the cautions of product misuses by the users. By adopting a safe design approach, it is possible to design-out health and safety hazards to create a design options that meet both clients need and our obligations as an engineer.[2] 4) Safe Design must meet standard of accepted engineering practice. Accepted engineering practice is a safety issues that involve fundamental ideas about how we view the world and what we believe is important and right. A designer has a responsibility to ensure that their conceptions do not put the others on risk. They cant just create the design by simply ignore insignificant risk even it consumes lots of cost. For example, it might be less important for a small house to install lightning protection but it is a must for such a large factories or tower to do so and to meet the standard of specification.[3] 5) Safe Design must verify every final design For good engineers, they must always find alternatives about how to improve their current products to improve safety effect besides implementing new ways of design. However, after designing, the products and finished devices must be tested rigorously to see whether the products are safe and meet the specifications needed. For fresh graduate engineers, they would be expected to work under the supervision and guidance of more experienced engineers, while they gain experiences. This is very important as fresh engineer will attempt to make more mistakes as they have lack of experiences.[2] DESIGNING FOR SAFETY Safety is generally interpreted as implying a real and significant impact on risk of death, injury or damage to property. In response to perceived risks many interventions may be proposed with engineering responses and regulation being two of the most common. Better safe than sorry by Bruce Erion, President of the National Broadcast Pilots Assn, a simple but crucial for designers to bear with. One version of the process for safety design, taken from the finding of Wilcox will be thoroughly elaborated. Some of the steps are including defining the problem and generate as well as analysing several solutions before implementing the design Consideration of safety should be an integral part of the design process at the various stages. Designers should assess the design as it progresses and if any significant hazard is identified the design should be altered to eliminate the hazard where reasonably practicable, or otherwise to reduce the risk where reasonably practicable [4]. As the design progresses from concept to detail, consideration of safety issues moves from general aspects to specific aspects. The most important contribution that a designer can probably make is at the concept and early design development stages of a project when project-wide and system hazards are being considered. Another important thing that an engineer needs to consider is to minimize the inherent danger in the process as could as possible. It is good if we can excluded any potential danger in our design rather that to cope with or otherwise avoided Hence, dangerous substances or reactions are replaced by less dangerous ones, and this is preferred to using the dangerous substances in an encapsulated process[3]. Trevor Kletz said that to eliminate the hazard completely or reduce its magnitude sufficiently to eliminate the need for elaborate safety systems and procedures. Furthermore, this hazard elimination or reduction would be accomplished by means that were inherent in the process and thus permanent and inseparable from it. Here we focus on the specific area of pertaining to engineering design. We believe that engineering design constitutes an interesting starting point for ethical issues in engineering, both for educational and research purposes [3]. The first step that designer need to consider is to define the needs and requirements and often involves determining the constraints. Consideration of safety should be an integral part of the design process at the various stages. Designers should assess the design as it progresses and if any significant hazard is identified the design should be altered to eliminate the hazard where reasonably practicable, or otherwise to reduce the risk. Before some design has been done, we must consider all the pros and cons before implementing every single one. We have to recognise if there any design trade off of the products. In order to build a stadium for example, Stadium A gives a more astounding structure but less safe compared to Stadium B that is very safe but the structural design is not that remarkable. Which one will we choose to build? Here, we need to generate several solutions in order to decide the best selection to choose but as a good designer, safety is always be the main priority Hence, after several solutions have been listed with their advantages as well as disadvantages, they need to be analysed. Safer products, processes and systems will result and that ultimately benefits business and society generally, now and in the long term, because it minimises injury and illness and provides for a better social and workplace environment. This step involves determining the consequences of each design solution and determining whether it solves the problem. The aspect of the design process is connected to, or brings about possible negative consequences, for people other than the designers involved; hence it is a must for engineer to test the solution whether they are safe enough before each of product has been released. Then after completing the solution testing, the design is ready to implement. In the nutshell, safety must come first in every design to avoid any unwanted accidents in the future and subsequent criminal or civil action against us RISK-BENEFIT ANALYSIS Risk-benefit analysis is the comparison of the risk of certain cases to its related benefits in the real world. Exposure to personal risk is recognized as a normal aspect of every daily routine life in human being. We accept a certain level of risk in our lives as necessary in order to obtain some particular benefits. In most of these risks one feels as though he or she have some sort of control over the real situation. For example, driving a car is a risk most people take every day. The controlling factor appears to be their perception of their individual ability to manage the risk-creating situation. However, analysing the risk of a situation is very dependent on the individual that doing the analysis. When individuals are exposed to involuntary risk or risk which they have no control, they tend to avoid the risk that they faced. Under these conditions, the individuals will favor to have the risk to be as much as one thousand times smaller than for the same situation under their pe rceived control.[7] Let us consider the adequacy of this way of dealing with uncertainty with the help of the simple conceptual model of risk management described by Figure 1. It characterises risk management as a non-monetized form of cost-benefit analysis. Figure1: simple conceptual model of risk management The model postulates that everyone has a propensity to take risks this propensity varies from one individual to another this propensity is influenced by the potential rewards of risk taking perceptions of risk are influenced by experience of accident losses ones own and  others individual risk taking decisions represent a balancing act in which perceptions of  risk are weighed against propensity to take risk accident losses are, by definition, a consequence of taking risks; the more risks an  individual takes, the greater, on average, will be both the rewards and losses he or  she incurs.[6] To make it simple, there are three kind of risk as shown in the figure 2. Figure 2: three kinds of risks Virtual risks are products of the imagination which work upon the imagination. The less conclusive the science relating to a particular risk, the more liberated are peoples imaginations. directly perceptible risks are managed instinctively and intuitively. Science illuminates many of the connections between behaviour and consequence, sometimes so successfully that previously invisible risks become directly perceptible. However estimates of such probabilities are usually of limited value to those seeking guidance about what to do in the face of uncertainty. There are at least as many problems attaching to the probability estimates as there are to the value estimates by which they are multiplied.[6] ACCIDENT Accident is an unexpected event that will be interrupt any completion of an activity, and that may be include injury or property damage. . Work accidents can occur due to unsuitable protective clothing and gear and insufficient training or non training. Injury can also be caused by careless co- workers and poor lighting. The employers should provide safe place of working, safe system of working and safe methods of working. When the accident was investigated, the important part is to find out what is the causes of the accident. It will use as a guideline in order to prevent similar accident in the future. The objectives of the investigation accident is actually to find out the facts that can guide to take the actions and not to find the fault. The investigation of the accident can be conducted by someone who have experienced in accident causation and have experienced about investigation technique. Besides that, the person must be have a knowledgeable about the working process or condi tion, the procedures and the person involve.[1] Most of the accident happen maybe because of some human error or else. For example, when doing the investigation, the accident is occur due to the worker carelessness. The accident happen still must be to investigate if there are not involve any injury or property damage because any hazards can be corrected for in the future apply. Accident can be considered into a several type which is procedural, engineered and the systemic. For procedural accident, it is the most common happen and it will give the someone to make a bad decision or choice and will not follow the established procedures. The procedural accident are quite well to understood and can be minimize with the appropriate way for example with the given training to the workers, more supervision, and must have laws or regulations .For engineered accident, it caused by flaw in the design. Failures in the choice of material, devices not operating properly, devices or parts not operating well under all circumstances. Engineered failure should be anticipated in the design stages and should be caught and corrected during testing. However, it not always to anticipate in every condition that will be encountered, and sometimes testing doesnt occur over the entire range of possible operating condition. Engineered accident cam be understood and alleviated as more k nowledge is gain through testing and actual experienced in the field.[1] For systemic accident, it is quite hard to understand and not easy to control it. They are characteristic of every complex technologies and the complex organizations that are required to operate them. For example in airline industry which have a very complicated system that involve many working people including baggage handler, machine, pilot, and so on. In designing some project, there are so difficult to detect any systemic accident since there are many small and seemingly insignificant factor that can be considered. As the designer and engineer, we suppose to understand the complexity of the system working and try to design something which the accident occur can be minimized. CASE STUDY CASE STUDY FOR SAFETY DESIGN Case Study 1 Safe Design: Employee received electric shock while trying to adjust damaged connector linking coin operated box to photocopier. 50mm connector jutting out at 90o on side of copier unsafe workplace-equipment layout obstructing access to electrical power outlet Preventive Actions Reopen case worksite preventive / brainstorming session with staff thru process of consultation, hazard ID, risk control measures. Re-layout photocopier and book shelf Case Study 2 Safe design: Nov 2004 Exhaust fumes from diesel engine at basement got into the air conditioning intakes on Floors 4 to 7, building was evacuated. When building was first built, there was no restriction to exhaust ventilation. With development, adjacent buildings were causing environmental restriction to existing exhaust ventilation systems, creating unsafe and uncomfortable workplace environment! Corrective action: Building owner to fix Preventive Actions: Development Act LG admin controls BCA building regulations controls Building Designers responsibility Case Study 3 Safe design: Jan 2005 Maintenance worker received electric shock after coming into contact with an LIVE evaporative cooling system isolation switch filled with water. Cause: Water droplets from the filter pad splashed onto the fan-motor power cable and gradually gained entry into the conduit and switch housing through gravity feed. Safe Design Consideration: Install a 90o elbow facing downwards at the cable entry point from the inside of unit to create the lowest dip point by design. Sealing the conduit entry point with silicone rubber or equivalent may not provide a permanent  barrier. CASE STUDY FOR ACCIDENT Case Study 4: Collapse of Stadium Terengganu Image of Terengganu Stadium Collapse In 2 JUNE 2009, the Stadium of Terengganu collapse after one year of being built. It was officially opened by the Yang di-Pertuan agong sultan Mizan Zainal Abidin. The roof of the stadium is named after him in Gong Badak, Kuala Terengganu collapsed in early morning of 2 June 2009 and causing damage to the few cars that was park in the vicinity. Fortunately no one was injured in this accident. The frame structure of the roof of the 50,000-seat stadium came crashing down around 7.30 am and none of the stadium staff were at the premises yet. 60 percent of the roof at the stadium that was built at a cost of RM270 million and opened on 10 May 2008, collapsed, including that above the royal box at the grand stand. Overall damage was estimated at RM35mil. Meanwhile, even after the debris from the 2,500-tonne roof has been cleared, the Terengganu government is  unable to say if the stadium is safe  as the impact of the collapse is not known. Some causes of the collapse of this new stadium were identified. It is maybe because of components used and work quality did not meet the specifications; design factor was not appropriate; roof was not constructed properly; quality control was not carried out at the project site; weak supervision during the construction process; lack of skilled workers; and shortage of experts and experienced consultants. A notice has been issued to the contractor to repair the 50,000-seat Sultan Mizan Zainal Abidin Stadium which is the biggest stadium in the East Coast but no response so far[9]. Case Study 5: The Crash of Valujet Flight 592 Image of Valujet Flight 592 In May 1996, Valujet Flight took off from Miami International Airport, heading for Atlanta. Theis Valujet Flight offered cheap fares to Florida and other popular destinations. It cost savings were achieved in part by hiring other companies which is Sabre Tech to perform many of the routine operations that keep an airline flying including the routine task of replacing oxygen generator canisters in some of its DC-9s. The canisters are located above the passenger seats and are used to provide oxygen to the passengers through masks should the cabin pressure somehow lost. The canisters contain a core of sodium chlorate, which is activated by a small explosive charge. This small explosion is initiated when the passenger pulls the oxygen mask toward herself. A chemical reaction within the canisters liberates oxygen, which the passenger breathes through the mask. During use, the surface temperature of the canister can be as high as 500F, which is normally not a problem, since the canister is well ventilated. To ensure that the canister will operate properly when needed, the oxygen generator canisters must be replaced periodically. Valujet maintenance rules made it clear that when the canisters are removed, a bright yellow safety cap must be installed on them to ensure that the explosive charge is not inadvertently set off. Unfortunately, Sabre Tech didnt follow this rule while performing this work. Instead, tape was applied where the caps should have been gone, and the canisters were placed in five cardboard boxes and left on a shelf in the hangar. However, two of the Sabre tech mechanics marked on the paperwork that the caps had been installed and signed off on the job. Within minutes after leaving the runway, the DC-9s electrical system started to fail and the cockpit and passengers cabin began filling with smoke. The pilots immediately called the Miami tower for permission to return and began to descend and turn back toward the airport. However, the situation becomes worsened because of fire started melting the control cables and the pilots become shrouded in smoke. The plane suddenly banked sharply and descended rapidly. The descent was so fast and causes the traffic control radar in Miami no longer able to register an altitude for the airplane. Amazingly, either through the efforts of the pilot or because the autopilot come back on, the plane becomes leveled off again. The airplane was now at only 1000 feet above the ground. The air traffic controllers in Miami radioed the pilots and attempted to send the aircraft to the closer airport at Opa Locka, Florida. Instead, the plane was rolled sharply to the right and facing nose down crashed into the Everglades. The two pilots, three flight attendants and 105 passengers on board were killed instantly in this accident. The subsequent investigation into this accident indicated that the fire was caused by the accidental firing of at least one of many chemical oxygen generators that were being carried in this plan to send back to Valujet headquarters in Atlanta. This chemical oxygen generator is the canister that had been removed from another Valujet airplane. The heat generated by this canister caused a fire in the cargo hold beneath the cockpit that ultimately brought this plane down. The investigation showed that this accident is not a flow in the airplanes design, but rather was attributed to a series of the oxygen canisters. These canisters were improperly secured and supposedly shouldnt have been on the airplane at all. One of the most important duties of an engineer is to ensure the safety of the people who will be affected by the products that he designs. As we have seen, all of the codes of ethics of the professional engineering societies stress the important of safety in the engineers duties [1][8]. CONCLUSION There are so many small insignificant factors that engineer doing that occur the accident. It may seem that the engineer has no responsibility and not alert about the law of safety and regulation. However, the engineer must understand and learn the complexity and the system that he is working on and also to be creative in determining how things can be design to avoid the accident happen again. Many of the risks can only be expressed by probabilities and no more educated guesses. Furthermore, there are synergistic effects between probabilities especially in a new and innovative design. Because of that, the engineer must design a product as safe as possible. Base on the designing for safety, the risk can minimize much more easierThe risk can minimize if the engineer spending more time to recheck the design cycle before sell it. It is because of to make sure that the product safe to use. Even though the price quite expensive, especially in the design cycle before the product has been built or is on the market, but the engineer must make sure that the product have a safety prevention and high quality. The prudent and ethical thing to do is to spend as much time and expense the design correctly so as to minimize future risk of injury and civil actions. The method to help analyze and to determine a project to proceed is risk benefit analysis. This method can summarize that the only ethical way is to implement risk-benefit by sharing the benefit between the engineer and society. As a conclusion, the product not surely 100% safe, but the engineer must design a product more effectively and follow the ethical law as a guideline.

Plant And Animal Cells Essay -- Biology Biological Cells Essays

Plant and Animal Cells I. Introduction All organisms in life are composed of at least one or more cells. Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two basic cell types. They are prokaryotic and eukaryotic. To distinguish where cells are placed in the two categories, what is inside the cell must first be looked at. Every cell, either prokaryotic or eukaryotic all contain basic cell parts. They are: a plasma membrane, cytoplasm, DNA (the genetic material), and ribosomes. Prokaryotic cells have a simple structure and they are usually smaller than eukaryotic cells. Also, most prokaryotic cells contain a cell wall. In addition to having the basic cell parts, eukaryotic cells also contain a membrane-bounded nucleus and cell organelles. The membrane surrounding the nucleus in eukaryotic cells, separate the nucleus from the cytoplasm. Most of the cells we used in the experiments held, were multicellular or consisting of more than one cell. A variety of cells were used in completing the experiments. We used union cells, cheek cells, potato cells, and Elodeo cells. We also used Planaria which is a unicellular organism. Many stains and dyes were used in the experiments. They were water, methylene blue, salts, and iodine. In our studies of cells, we conducted three experiments to test the different features of cells. The first two experiments were on how membranes were selectively permeable, diffusion, and osmosis. To test this, we set up two experiments. The first experiment we set up had three cups. In each cup a potato slice and a different liquid was put in. In the first cup was filled with distilled water. The second cup was filled with salt water and the third was left empty. We left these cups sit for twenty- four hours and then we observed them. The second experiment we set up involved dialysis tubing which was acting like a membrane. In the dialysis tubing we put a liquid that was made of starches and sugars. We then put the dialysis tubing into a beaker of water wh... ...c solution and sucked up some of the water in the cells. When we observed the cheek cells we found they were very different from the plant cells. The nucleus was in the middle of the cheek cells and there were a few cell organelles. The Planaria cell was all red and had lines running down it. In this cell though, the nucleus was not present. The plant cells and animal cells were very different. In the plant cells there was motion of cell parts but in the animal cells there was no motion. Also, the nucleus and chloroplast of the plant cell were towards the outside of the cell because the chloroplast can receive sunlight better on the outside of the cell than on the inside. In the animal cells though, the nucleus and cell organelles, were towards the middle of the cell. III. Conclusions All organisms in life are made of at least one or more cells. Cells are the basic units to life. Without cells life cannot exist. In our experiments we went to look how cells function and what are their features. In finding this information, I know have a better understanding of how cells function and their specific features.

Lenin’s death in 1924 Essay

12 marker: Explain why; at the time of Lenin’s death in 1924 there was no obvious successor to lead The USSR. Lenin’s death came as a great shock to many Russians in 1924; he led the October Revolution in 1917 he was seen as father like role to Russians. He had built up a new government and allowed many of his fellow Bolsheviks roles positions in his new Soviet State, and these figures all thought that they have the power and influence to lead Russia. Lenin knew that he was ill and that he would not be able to keep on making key decisions and attending committee and politburo meetings. He felt that the people in his government saw this as an opportunity to try and assert their power and then after his death have a good chance of becoming the leader of The USSR. He wrote a testament, damning five of the people that held high authority in his new government: Trotsky, Stalin, Bukharin, Zinoviev and Kamenev. If this were to be circulated in the party it would mean that people lower down in the party would be questioning these people too, they might feel that these individuals had too much power. However, these were the leading communists and there did not seem to be any other Bolsheviks that were capable or ready to become a leader. Lenin called Trotsky ‘excessively self-assured’ Lenin thought that Trotsky focused too much on himself and not enough on the Russian people. Lenin also called Stalin the other main contender for the role of leader ‘too rude’ and stated that he has been placed with too much power within the part as Secretary-General; this has made him quite arrogant. Lenin calls for Russians to remember that although Zinoviev and Kamenev are quite underestimated, that they were not loyal to the October Revolution and therefore not the most trustworthy or loyal. Lenin feels that Bukharin is very intelligent, and would be good at the administration aspect of leadership but not a good enough orator to be seen as a strong leader by the masses. This really set the cat among the pigeons; it showed that Lenin did not have confidence in one single successor, showing negative aspects of all of the possible candidates. Although this was suppressed by Kamenev and Zinoviev from being read at the 23rd party conference, Stalin had the most to lose if this had been read, being very critical of his personality and power. Ultimately, it showed that there was going to be a power struggle, and that there was no obvious successor. Lenin’s Testament highlighted some major concerns of his, that there were five possible successors but none of them seemed obvious to go straight to the leadership position. Trotsky was seen as an alternative main candidate, he had a lot of support from the working class in the two main cities, Moscow and Petrograd. He was educated and a brilliant orator, moving crowds of people that came to visit him speak. However, he had many personal weaknesses, he was not liked by a lot of the main decision makers under Lenin, and he needed their support for a leadership position. He did not understand that Russia was an agricultural country and he had to think of the country’s agriculture as much as its industry. Stalin had many important roles within the communist party, commissar for nationalities, worker’s and peasant’s inspectorate and more. Although he had a vast amount of power within the party he was not seen as being consistent, something a leader should be. Also, he had a tough relationship with Lenin before his death. Bukharin was seen as very clever, but not being Marxist enough, he had been appalled by the bloodshed of the civil war and supported the NEP that had allowed an emergence of a middle class, something the Revolution was against. Also Bukharin did not take any side in arguments within the party, showing Lenin that he maybe was not a committed communist. Zinoviev and Kamenev had not been loyal to the October Revolution in 1917; showing that they would not be the leader that Lenin wanted. Lenin thought that they buckled under pressure and for these two reasons did not allow them on the Russian bureau of Central Committee. These factors reinforce the uncertainty for the role of leader, there were candidates that seemed to be strong like Stalin or Trotsky but they had large weaknesses too. Although, there was a lot of room for possible criticism and backstabbing due to the contenders having weaknesses of their own, in 1921 the ban on factionalism introduced by Lenin stopped the formation of groups within his party and stopped criticism of decisions made within the party. It was a way of trying to make the party seem loyal and was basically a ban on free-speech: Meaning that the candidates would not be able to run for leader by highlighting weaknesses to the party or masses. The five candidates would not be able to campaign. Also, because Lenin’s Testament was not published it did not allow the party to make a decision on the leadership, alongside the ban on factions meant that a candidate would just have to seem like a strong runner individually or resort to backstabbing. In conclusion, I believe that by not publishing Lenin’s testament, this meant that his personal opinions were not voiced to the party, at the party conference, where hundreds of the most influential communists would have seen that all of the main five candidates had weaknesses and there was not one that Lenin felt was singly good enough to rule the party. He was possibly hinting to a collective government with a coalition between all five, mixing their positive aspects to make a great USSR. Although the ban on factions was important, the Testament would have voiced the weaknesses of the five people in the running for leadership coming straight from Lenin his conclusion would have gained influence from the party that was loyal to him. Therefore, I believe that by not publishing Lenin’s testament meant that there was great uncertainty over the role of leader.

Intro to Bio Essay

1. What patterns do you observe based on the information in Table 1? The patterns that I observe based on the information in Table 1 is that the more dissolved oxygen contained in the water, the more fish are observed in that particular area of water. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. The hypothesis that I would develop relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water is if there is more dissolved oxygen contained in the water, there will be more fish present in the area the water sample is being taken from. 3. What would your experimental approach be to test this hypothesis? My experimental approach in order to test this hypothesis would be to test the dissolved oxygen contained in different areas of water and keep track of the fish in those areas and then compare the results. 4. What are the independent and dependent variables? The independent and dependent variables are the independent is the dissolved oxygen and the dependent is the fish. 5. What would be your control? What would be my control is no control. 6. What type of graph would be appropriate for this data set? Why? The type of graph that would be appropriate for this data set would be a line graph because it will support the hypothesis that I came up with as well as provide clear results. 7. Graph the data from Table 1: Water Quality vs. Fish Population (found at the beginning of this exercise). You may use Excel, then â€Å"Insert† the graph, or use another drawing program. You may also draw it neatly by hand and scan your drawing. If you choose this option, you must insert the scanned jpg image here. 8. Interpret the data from the graph made in Question 7. The data from the graph shows the population of fish on the Y axis and the dissolved oxygen on the X axis. The population of fish increases in the graph because of the increased amount of dissolved oxygen found in the body of water.
