Today, slavery is not something you see in modern day society. For the most part, people are treated fairly while working, are given benefits such as holidays and the option to take a sick day when feeling ill, and are paid a good wage for their services as an employee. But unfortunately this was not the case back in the 1800s where slavery was popular among the southern parts of the United States. How It Started Slavery grew in the 1800s due to the demand for more workers to help on plantations, particularly in the southern states. The northern states didnt need slaves because they didnt have as many large farms as the south did.

They hardly ever got days off, only on Sundays and holidays that were not frequent, such as Christmas. After a long day of working, slaves then had personal free time. This is the time that they used to make food and clothing for their families. Since slave owners last priority was their slaves comfort, they often provided the bare minimum for their slaves survival. They didnt want to waste money on luxuries, but they did want to keep them alive and well enough so that they could still work for them. When they retired for the night, the slaves called a small stick shack with a dirt floor home. These shacks had a lot of cracks in the walls and this let in the cold and harsh wind. The windows only had thin coverings as well.  Again, bare minimum and maximum profit were all that the slave owners cared for. There was one thing that the slaves did have control over though. They could get married and have children. But the slave owner did have the power to break up families by selling certain members. Also any children that were born were property of the slave owners.  The slave owners actually encouraged slaves to have families because this meant that they would have more workers at their disposal. Slave owners often would punish any slaves that tried to educate themselves.

Lab on solutions Essay I IntroductionA. Purpose: The purpose of this experiment was to determine if the temperature of water effects the rate at which salt dissolves. B. Hypothesis: If the temperature of the water increases then the rate at which the salt dissolves will increase. C. Science Concepts: Solution- one substance dissolved in anotherSolute- the substance that gets dissolvedSolvent- the substance that the solute gets dissolved inCharacteristic property- a property that is unique to a substance, does not change depending on the amount of a substance, and can identify the substancePhysical change- when a substance changes physically but is not chemically effectedSolubility- the amount of a substance that can be dissolved in a given amount solvent at a given temperature In the experiment the solubility of salt was tested in different temperatures of water. The solute was the salt and the solvent was the water. The salt dissolved in the water to form a solution. When the salt dissolved a physical change took place. Solubility along with melting point, freezing point, and density is a characteristic property. II Procedure 1. massing cups and a triple beam balance were used to measure 0.5 grams of salt2. 100 ml of cold water was measured and poured into a beaker using a graduated cylinder3. the temperature of the water was measured and recorded on a data table4. the salt was poured into the water and the stop watch was started5. the water was stirred as the salt crystals dissolved6. the number of seconds it took for the salt to dissolve was measured and recorded on a data table7. the experiment was repeated using room temperature and warm water8. each group did one trialIII Results/ConclusionsA. Experimental Data: The results of the experiment indicate that the warmer the solvent was the faster the solute dissolved. When the water was 9C it took 51.66 seconds to dissolve. When the water was 57C it took only 13.15 seconds to dissolve. B. Graphs and Tables: see attachedC. Evaluate Prediction/Hypothesis: The results of the experiment support the hypothesis. The hypothesis stated that the slat would dissolve faster if the water was heated. The salt in the warmer water dissolved about four times faster than the salt in the cold water. IV Extension and SummeryA. Extension: Some causes of experimental error may have been how fast the stirrer was stirring. This could have been fixed by having the same person stirring each time. Another possible cause of experimental error could have been if the temperature was measured incorrectly. This could have been fixed by using a digital thermometer. A related experiment that could be done is if the rate at which sugar is effected by the temperature of the water. B. Problem Question: Is the rate at which salt dissolves in water effected by the temperature of the water? The results of the experiment indicate if the water is warmer the rate at which the salt dissolves increases.

Long Lab Report Blackworm Paper Blackmore have a closed circulatory system, which in the Blackmore includes a large dorsal blood vessel Glucose is the most common carbohydrate and is classified as a macroeconomics and is a reducing sugar. Glucose is called blood sugar as well because it circulates in the blood. When blood glucose is high, the pancreas releases insulin, which then helps to transport glucose into muscle or liver cells. There, its used for energy. If theres more glucose present than needed, insulin helps the glucose to be stored in adipose tissues as fat for potential future energy needs. One immediate effect of the breakdown and conversion of glucose into cellular energy is an increased metabolism, which can manifest itself in the form of increased heart rate, high blood pressure or some other form of arousal such as heightened mental alertness If the black worms are placed in a glucose solution, breakdown and conversion of glucose will be inhibited and cause their hearts to beat faster. In this experiment, it was hypothesized that when black worms were exposed to a solution of mm glucose, their average pulsation rate per minute would Increase. Methods: The procedure of Lab 7 was the same as Lab 6 Part B except the black worms were exposed to a glucose solution before their pulsation rates were measured. Results: In this experiment black worms that were exposed to only spring water and no glucose were used as the control. When the pulsation rate was taken for the control black worms exposed only to spring water, the average pulsation rate was 16. 534 beats per minute with a standard deviation of 1. 849 as seen in table 1. When the pulsation rate was taken for worms exposed to a glucose solution of pm.

Human Error and Human Human Error and Human-Computer Interaction Essay Human Error and Human-Computer Interaction Essay The context of human error has been considered as one of the most important issues because of its enormous effect in both human and economic aspects. Accordingly, all humans have experienced human error. Errors can be made when people interact with machines and other complex systems. Herein, people have a tendency to do things which are contrary to their expectations and intentions. Depending on the complexness of a certain system and the human intentions that interacts with it, errors can be anything from a discomfort (which are often unnoticeable) to a actual tragedy or calamity. Human error an happen in the plan, design, management, operation as well as maintenance of complex systems characterized by the modern life. Since humans, depend largely and increasingly on these systems to have a better living, it is transparent that human error has a potentialities and has a frequent source of risks to human life and welfare as well as the natural environment (Senders Moray, 1991). Errors in human can result in both human and economic cost. In line with the human factor, errors can result to anxiety, depression, disappointment and stress at work which may result in the inability of the individual to finish their tasks or responsibilities effectively and mat also lead to negative emotions. In terms of the economic aspects, the economic costs largely depend on the error numbers as well as the time spent in the diagnosis of such error and the recovery. Because of these enormous effects, researchers and scholars has spend their time in analyzing and understanding the context of human error. There are various areas or fields in which human can occur, and one of these is the errors in Human-computer interaction (HCI). Primarily, the main goal of this paper is to determine the relations of human error with Human-computer interaction. Part of the discussion of the topic is the definition of human error and the types of human errors. This paper also attempts to provide practical examples of human errors and the future perspectives, reduction and prevention of human error. Pertinent conclusion will also be provided to summarize the findings of this report. For many years, many scholars and researchers has been trying to determine the nature and definition of human error. Human error is regarded as departure from expected, desirable and acceptable practice on the individual part which can result in undesirable and unacceptable results or outcome. Accordingly, human error has played a very crucial role in various large-scale hazardous and life-threatening events and occurrences (Reason, 1990). Some researchers believed that human error might not be an accident because of itself but it might be a result of multiple factors which are not able to control (Reason, 1990). As mentioned earlier, human error can error in various fields from military, politics, economic, computer systems, medical fields, engineering and others. It is said that errors, specifically the human errors are rare occurrences as compared with correct actions or successes. The kinds in which errors can take are restricted and may appear in variety of contexts, but only a few behavioral approaches seems to be accountable for all such errors (Rizzo, Bagnara Visciola, 1987). Nonetheless, comparable types of errors can be seen in perception, speech, problem solving, decision making and actions. However, human errors are less likely to happen tasks are automatic or skilled based such as driving, than when the action call for a rule or process to be considered. It is noted that those actions which call for the utilization of knowledge to solve new issues and conflicts are regarded as the most vulnerable tasks to human errors. The reason for this is because knowledge, like principle, should be translated into correct course of concrete actions, hence, error can be encountered in this translation process (Bogner, 1994). An error has always been attributed to a mismatch of the computer system to human nature and capabilities (Rasmussen, 1987). To illustrate, controversies, technical problem, lost files, or other mistakes in relation to the use of computers are often blamed to either the machine or the human. Errors paved the way to the creation of back up files, for example, and the improvement and innovation of machines to assist humans in working or accomplishing their tasks faster and easier. Human error definition has not only been the subject of the interest of the scholars and researchers but also the types of human error. According to some scholars there are two types of human errors in accordance with the systematic causes of failure. These types of human error include the active errors and latent errors. As Reason (1990) has noted, active errors are errors whose effects are immediately felt. Such errors include syntax error which prevents the efficient compilation or invalid algorithms. On the other hand, Reason (1990) has defined latent errors as errors in which adverse consequences may lie dormant within the system for a long period, and only becomes obvious when such is combined with other factors to hinder the defenses of the system. Aside from Reason, Rasmussen (1982) has also been able to provide other types of human error and these include knowledge based, rule based and skill based human error (see Appendix 1). The taxonomy of human errors is needed when discussing or understanding errors that people encounter with the use of machine. Examples of errors include functionality problems, usability problems, inefficiency, and interaction problems. Functionality Problems Functionality problems refer to the mismatch between the task and the program. This mismatch occurs when ones plan has not been accomplished or oneÃ¢â¬â¢s goal has not been achieved with the use of particular computer program. Functionality problems are classified according to technical criteria like origin in the process of software development and consequences for the action process (see Appendix 2; Brodbeck et al. , 1992). Usability Problems Although the functionality of a computer program is sufficient for a certain task, errors still occur. They can be caused by a mismatch between user and computer, called mismatch of usability. From an action-theory perspective, mismatches of usability can be differentiated according to steps in the action process and different levels of action regulation. A common hypothesis in action theory is that actions are goal-oriented (Volpert et al. , 1987). Within this approach, the action process comprises goal and plan development, the execution of actions as well as monitoring, and feedback processes (Lewis Norman, 1986). Similar to Hacker (1986), three levels of action regulation are distinguished within the framework of hierarchically organized action plans and goals. There are at least three aspects of the knowledge base for regulation: knowledge of facts, knowledge of procedures, and understanding in the sense of mental models. This knowledge is used to develop goals and plans. Errors arising from usability problems include errors in knowledge, thought, memory, judgment, errors on the level of flexible action patterns habit, omission, recognition, and sensimotor (see Appendix 3. Knowledge errors occur when one is unable to do a task with the computer because one does not know certain commands, function keys, rules, and so forth. Thought errors occur when goals and plans are inadequately developed or when wrong decisions are made in the assignment of plans and subplans although the user knows all the necessary features of the system. Memory errors occur when a certain part of the plan is forgotten and not executed, although the goals and plans were initially correctly specified. Judgment errors appear when one cannot understand or interpret the computer feedback after an input. Errors on the level of flexible action patterns occur when well-known actions are performed. Habit errors imply that a correct action is performed in a wrong situation. Omission errors happen when a person does not execute a well-known subplan. This is most likely when the person is interrupted in an action plan. Recognition errors appear when a well-known message is not noticed or is confused with another one. Finally, sensorimotor errors are placed at the sensorimotor level. There is only one category here because, at this level, it is empirically difficult to differentiate among planning, monitoring, and feedback (see Appendix 4; Brodbeck et al. , 1992). Inefficiency Errors and inefficient behavior have a large conceptual overlap. A detour to reach a goal may be conceptualized as an inefficiency but also as an error, because usually ones goal is to proceed in the most straightforward manner. If there is any differentiation between the two terms, inefficiency could be formally defined as any deviation from an optimal action path (Volpert et al. , 1981). However, this conceptualization has its difficulties: it may be more cost effective, in the psychological sense, to use a strategy that is inefficient in the formal sense because setting up plans and differentiated calculations for them also imply psychological costs (Schonpflug, 1985). Interaction Problems Interaction problems suggest that human error occurs not because of individual problems with the computer, but because of the mismatch between individuals. Although the individuals actions are more or less correct, an error occurs because of an organizational lack of coordination, unclear task allocation, or because of lack of communication between individuals (Brodbeck et al. , 1992).

Bill Clinton and Globalization - Research Paper Example ClintonÃ¢â¬â¢s main focus was on handling the instability across the world through globalization. The other factors among the list of priorities were innovation and technology, decision making and finance. Integration of the world economy has been one of the prime concerns of Clinton. But the concept of transformation of the globalization into a unified and homogenous structure driven by free trade and capitalism was confronted with serious opposition also. It was said that the entire world has not been able to benefit from globalization and bringing the civil society in the scene was the only way of dealing with the problems. The project tries to bring forth the steps taken by Clinton in initiating outsourcing as a major step towards globalization (Weier-a, 2008). Bill Clinton chaired the Ã¢â¬Å"Global Fairness Initiative (GFI)Ã¢â¬ (Global Fairness Initiative, 2003, p.1) which was an organization created to introduce and enhance free trade which would simultaneously preserve th e labor, environmental and human rights standards in the world. The promise made by Clinton was to implement responsible investment and trade which would create economic opportunities and jobs across the world and would lead to the improvement of millions of lives while protecting the human rights, environmental and labor standards (Global Fairness Initiative, 2003, p.1). The promotion of outsourcing was one of the major steps towards globalization by Clinton. Outsourcing was considered to be inherent to free trade. Outsourcing was considered to be a new variant and a budget balancing tool which required farming out whenever possible. Clinton recognized that outsourcing would allow firms to provide service at a low cost at a higher quality that which the Government would produce. In the recent years outsourcing has evolved as a positive business evolution which moved towards flexibility and nimbleness Bill Clinton and Globalization It was Bill ClintonÃ¢â¬â¢s assumption that global ization was something inevitable. He encouraged the concept of free trade which was a major step towards globalization. He believed that low process would lead to low prices, increased exports and this would eventually build a stronger economy. Ã¢â¬Å"The economic benefits of the tariff reductions we negotiated during the Clinton administration represent the largest tax cut in the history of the worldÃ¢â¬ (Klein, 2003). In 1998, the economic transition which he had predicted long back was actually taking place. The economy was appearing and functioning in such a way that seemed to be beyond imagination few years back. Unemployment rates were falling significantly and the inflation rates seemed to remain at historically low rates. Prosperity was appearing and increasing at all levels of income. The average household income increased by an amount of 35% during the span of eight years that Clinton has remained in office. Technology had changed the conventional notions of time, space and borders. Globalization was able to change the traditional and regular routines of the middle class family. This was a significant transformation according to Clinton (Klein, 2003). He said the globalization would yield a global economy which would have profound effects on workers, their works and their wages. It would
