TD 4- HRM - 402 Delivering Training and Development Essay
TD 4- HRM - 402 Delivering Training and Development - Essay Example Following the amount of factual data and interpersonal skills needed, the blended learning method is the most suitable as each of the individual methods used contribute to more quality delivery of training and development. Since lengthy sessions are involved in delivering facts and developing skills, the rationale of choosing the blended learning method is to ensure that different learning levels are adapted as various departments within Wal-Mart require different levels of competency from different ranks of employees(United States Department of Labor, 2010), Guthrie, A.

History Civil War Movie - Lincoln (2012) Review Example | Topics and Well Written Essays - 500 words
History Civil War - Lincoln (2012) - Movie Review Example The movie appreciates the most remarkable historical event in the American history. The movie displays the efforts put forward by Abraham Lincoln during his last years in power to pass the 13th Amendment in the U.S. Constitution with the help of the House of Representatives. In this sense, some social issues like the rights to vote by the African Americans and women and slavery are among the contributors to its amendment. In Lincoln (2012), a key issue revolves around social class and not race. Lincoln used the North Industrialists to fund most of his campaigns because it gave them the power to levy heavy taxes on people living in the South so that the companies in the North can grow. Through this, there seems to be a divide between the two regions. The North was keen about economic prowess, land ownership, free markets and owning the bank of the United States. Since the South did not have a good representation, it underwent oppression through taxes. Regarding interests, the North wa s a racist hub with slavery being dominant in the South. Through this Abraham Lincoln, while relating to the movie, the Unite States was able to enforce the Thirteenth Amendment in her constitution. In the amendment, the senate abolished the widespread slavery and involuntary servitude. The only exception in this amendment is when slavery is used as a corrective measure especially when punishing criminals. Though the movie carries a good message, its storyline has no concrete documentation. Critics term the Lincoln (2012) movie as a misleading historical movie. For instance, in this movie, Lincoln, who is the President of the United States orders two of his congressional representatives to use all means to pass the 13th amendment. The President in the movie uses this phrase to show authority: Critics in some way agree with the quote because historical documentation proves so. However, the tone in the command, the facial expression as well as the context in which it

Roles Of Human Resource Management
Roles Of Human Resource Management In the past few years, roles for HR professionals were viewed in terms of transition from operational to strategic; qualitative to quantitative; policing to partnering; short-term to long-term; administrative to consultative; functionally oriented to business oriented; internally focused to externally and customer-focused; reactive to proactive; activity-focused to solutions-focused (Ulrich, 1997). However, these transitions have been seen as too simplistic. In fact, the roles of HR professionals are multiple, not single. In order to create value and deliver results, HR professionals must not only focus on the activities or work of HR but also define the deliverables of the work. Therefore, Ulrich (1997) came out a multiple-role model for human resource management (See Figure 2-1). The two axes represent the HR professionals focus and activities. Focus ranges from long-term/strategic to short-term/operational. HR professionals must learn to be both strategic and operational, focusing on the long term and short term. Activities rang from managing process (HR tools and systems) to managing people. These two axes delineate four principal HR roles which are: (1) Management of strategic human resources; (2) Management of firm infrastructure; (3) Management of the employee contribution; and (4) management of transformation and change (Ulrich 1997). In a short word, the roles of HR professional are strategic partner; administrative expert; employee champion and change agent. Table 2-1 summarizes the deliverables, metaphor and activities the HR professional must perform to fulfill the role. Figure 2-1 HR Roles in Building a Competitive Organization Source: Ulrich, 1997 Table 2-1 Definition of HR roles Role/Cell Deliverable/Outcome Metaphor Activity Management of Strategic Human Resources Executing strategy Strategic Partner Aligning HR and business strategy: Organizational diagnosis Management of Firm Infrastructure Building an efficient infrastructure Administrative Expert Reengineering Organization Processes: Shared service Management of Employee Contribution Increasing employee commitment and capability Employee Champion Listening and responding to Employees: Providing resources to employees Management of Transformation and Change Creating a renewed organization Change Agent Managing transformation and change: Ensuring capacity for change Source: Ulrich, 1997 Management of Strategic Human Resources-Strategic Partner As Ulrich said, HR professionals pay a strategic role when they have the ability to translate business strategy into action (Ulrich, 1997). To achieve this, the HR manager must be able to ask appropriate questions and contribute to business decisions. As a result, the HR manager must develop business acumen, a customer orientation and an awareness of the competition to be able to link business strategy to HR polices and practices. However, research suggests that only a minority of CEOs involve their HR managers in formulating business strategy (Nankervis, 2000 and Johnson, 2000). Evidence indicate that there is growing awareness of the need for HR managers to become actively involved at the strategic level, and increasingly recognize that organizations that have a CEO who recognizes the significance of HRM have a competitive advantage (Fisher and Dowling, 1999; Way, 2000). Management of Firm Infrastructure-Administrative Expert According to Ulrich, to become administrative experts, HR professionals must be able to reengineer HR activities through the use of technology, rethinking and redesigning work processes and the continues improvement of all organizational processes; see HR as creating value; and measure HR results in terms of efficiency (cost) and effectiveness (quality) (Ulrich, 1997; Blackburn and Rosen, 1995). Research also indicates that the competency levels of HR managers in high-performing firms are significantly higher than those of HR managers in low-performing firms (Yeung, 1998) Management of Employee Contribution-Employee Champion Work as employee champion requires that the HR professional must be able to and meet the needs of employees. This can achieve by being the employees voice in management discussions, by being fair and principled, by assuring employees that their concerns are being heard and by helping employees to find new resources so that enable them to successfully perform their jobs (Ulrich, 1997). Failure to be an employee champion will see HRM facing a loss of trust for losing sight of the needs, aspirations and interests of the workforce (Kochan, 2003). Ignoring employee-related outcomes may result in lower jog satisfaction, lower commitment and reduced performance, which in turn, negatively affect organizational performance (Guest, 2002). Management of Transformation and Change-Change Agent Act as change agent can be achieved by learning change in the HR function and by developing problem-solving communication and influence skills. Gloet argues that one way for HRM to reinvent itself is via the development and maintenance of learning environments, where knowledge creation, sharing and dissemination are valued (Gloet, 2003).

The economic reform in China has led to impressive growth and significant integration into the global economy. These developments have resulted in major changes in the management of industrial enterprises and hold considerable implication for HR practices in the nation with the largest workforce in the world. In China, HR practices have been shaped by a host of ideological, historical, political and economic factors. Under the economic reform programmed, although some market forces have been introduced into the HR system, the influence of the state is still considerable (Nyaw, 1995:193). In 1979, China introduced the open door policy. Since then, economic reforms have brought many changes to the business environment. The end of the iron rice bowl policy has created a new employment market. SOEs have to compete with joint ventures and privately owned enterprises. With reforms in HR practices, managers in SOEs have more a utonomy including the authority to hire and fire. There are significant differences in HR practices between firms of different ownership. MNCs and joint ventures have brought into China not only investment but also management practices. For example, labour contracts have replaced lifetime employment. A performance-based pay system is gradually replacing the seniority pay system. These practices have an important influence on domestic firms in changing their HR practices (Warner, 2001) Benson and Zhu (1999) observed that there were three major models of HRM in Chinese enterprises. The first was a traditional model that existed in large SOEs where there was surplus labour. These SOEs had close ties with the government and contributed to local development. They had traditional HR management systems. The second model was observed in foreign-owned enterprises or newly established domestic private enterprises. They had fewer constraints than SOEs. They realized that their success based either on western or Japanese systems. The third model was observed in firms that were undergoing a transition from the old to the new systems of HR management. They adopted a HR management style with Chinese characteristics. Nyaw, M.K. (1995) Human resource management in the Peoples Republic of China, in Moore, L.F. and Jennings, P.D.

(1999), Markets, firms and workers: The transformation of human resource management in Chinese state-owned enterprises, Human resource management Journal, Vol.9., No.4, 58-74. 2.3 Human Resource Management Outcomes HRM is concerned with both organizational performance and employee wellbeing which means that any evaluation of HRs contribution must incorporate both organizations and employees perspectives. The contribution of HRM to the organizational performance included aligning HR strategies with organizational strategies, managing the corporate culture to win employee commitment and being efficient in managing HR activities. On the other hand, the contribution to individual wellbeing relate to employee attitudes and behavior. High-performance HRM benefits the organization because the way employees respond to HRM initiatives is linked to their job performance and ultimately to organizational performance (Guest, 2002). Therefore, when evaluate HRM performance, following outcomes should be considered: Adaptability: that means HRM strategies and policies foster organizational and employee flexibility. The whole organization and employee ready for change and accept change. After that, innovation and creativity encouraged, knowledge is recognized as a critical asset and the organization utilize people with different background and value systems. Commitment: this concern with HRM policies enhance employee identification with and attachment to their job and the organization. High level of commitment can result in more loyalty, increase teamwork and reduced labour turnover, along with a greater sense of employee self-worth, dignity, psychological involvement and feeling of being integral to the organization. Competence: Relates to the extent that HRM polices attract, retain, motivate and develop employees with the abilities, skills, knowledge and competencies to achieve the organizations strategic objectives. Congruence: concern with HRM polices generate or sustain congruence between management and employees, different employee groups, the organization and the community, employees and their families, and within the individual. In other words, HRM strategies and policies promote the achievement of employee goals, at the same time, satisfy the organizations strategies business objectives. Lack of congruence can be costly to the organization in terms of time, money and energy, resulting low levels of trust and lack of common purpose and stress or other psychological problems will happen (Beer, Spector, Lawrence, Mills and Walton, 1984) Cost-effectiveness: the HRM strategies and polices can reduce personnel-related costs, help correctly size the organization, eliminate unnecessary work, reduce compensation and benefit costs, reduce labour turnover and absenteeism, improve employee health and safety, improve employee productivity and avoid costs from litigation and negative public relations. Job satisfaction: HRM strategies and polices can produce employees have positive attitudes and feelings about their jobs. Common employee satisfaction components include pay, promotion opportunities, fringe benefits, supervision, colleagues, job conditions, the nature of the work, communication and job security (Spector, 2000). Rose (2002) suggested that employees frustrated and bored with repetitive and standardized work have low commitment. A satisfied employee tends to be absent less often, make positive contributions, stay with the organization and radiate positive feelings towards customers (McShane and Von Glinow, 2000). Justice: HR strategies, polices and practices are powerful communicators regarding managements trustworthiness, fairness and commitment to employees. If management is perceived favourably, employees reciprocate with increased commitment to the organization (Whitener, 2001). Motivation: HRM strategies and policies stimulate employees to achieve a designated goal. Highly motivated employees work hard, come to work early and contribute more to the organizations strategic objectives. Performance: HRM contribute to employee job performance and productivity and the organizations overall profitability, growth and success. Trust: HRM promote trust between employees, management and the organization. Under trust, employees are willing to share information, genuinely cooperate with one another and not take advantage of other.

However, what causes employee satisfaction? The researchers Judge and Bono (2001) found that one of the primary causes is the perception of the job itself. And also job itself is the most important situational effect on job satisfaction. Other research also show that of all the major job satisfaction areas, satisfaction with the nature of the work itself which includes job challenge, autonomy, variety and scope are best predicts overall job satisfaction (Fried and Ferris, 1987; Parisi and Weiner, 1999; Weiner, 2000). Some general statements about the facets that seem to contribute the most to feelings of job satisfaction for most North American workers include mentally challenging work, high pay, promotions and friendly or helpful colleagues (Locke, 1976). For more detail, Spector (1997) concluded that the causes of job satisfaction can be classified into two major categories. First, the job environment itself and fac tors associated with the job are important influences on job satisfaction. This includes how people are treated, the nature of job tasks, relations with other people in the workplace, and rewards. Second, there are individual factors that the person brings to the job. This includes both personality and prior experiences. Both categories work together to influence employee job satisfaction. In this study, we mainly focus on the environment antecedents of job satisfaction. Following factors are the environmental causes of job satisfaction: Job Characteristics and Job Characteristics Theory Many studies have advocated job design as a means of enhancing job satisfaction by making jobs more interesting (Herzberg, 1968; Herzberg, Mausner and Snyderman, 1959). The job characteristic theory is that people can be motived by the intrinsic satisfaction they find in doing tasks. When they find their work to be enjoyable and meaningful, people will like their jobs and will be motivated to perform their jobs well (Hackman and Oldhams, 1976). The characteristics model see figure 2-2. Figure 2-2 Hackman and Oldhams (1976) Job Characteristics Model Core Characteristics Critical Outcomes Psychological States Skill Variety Task Identity Task Significance Experienced Meaningfulness Autonomy Experienced Responsibility Feedback Knowledge of Results Work Motivation Job Performance Job Satisfaction Attendance Growth Need Strength Source: Hackman and Oldhams, 1976 Organizational Constrains Conditions of the job environment that interfere with employee job performance are called organizational constraints. The constraints come from many aspects of the job, including other people and the physical work environment. As the study of Peters and OConnor (1980), organizational constraints have been shown to relate to job satisfaction. Significant relations have been found between various measures of constraints and job satisfaction (Jex and Gudanowski, 1992; Keenan and Newton, 1984; OConor et al., 1984; Spector et al., 1988). OConnor, Peters, Rudolf and Pooyan (1982) reported correlations of organizational constraints with five job satisfaction facets which are coworker, pay, promotion, supervision and work itself. Work-Family Conflict Work-family conflict has been found to correlate significant with job satisfaction. Employees who experience high levels of conflict tend to report low levels of job satisfaction (Bedeian, Burke and Moffett, 1988; Holahan and Gilbert, 1979; Lewis and Cooper, 1987; Rice, Frone and McFarlin, 1992). Organizations can adopt policies that either help people cope with or reduce work-family conflict. Thomas and Ganster (1995) studied the impact of organization policies and supervisor behavior on employee experience of work-family conflict and job satisfaction. Their research provides evidence that organizational policies such as child care and flexible work schedules can reduce work-family conflict and enhance job satisfaction. Behavior by supervisors that supports employees with family responsibilities was also found to have positive effects. Pay The correlation between level of pay and job satisfaction tends to be surprisingly small. Spector (1985) found a mean correlation between level of pay and job satisfaction. However, although pay level is not an important issue, pay fairness can be very important. Rice, Phillips and McFarlin (1990) reported a moderately large correlation between pay level and job satisfaction in a sample of mental health professionals who all had the same job. Workload Workload has been found correlated with job dissatisfaction as well as other job strains (Jex and Beehr, 1991). Jamal (1990) found significant negative correlations of workload with job satisfaction, and Karasek, Gardell and Lindell (1987) found that workload was negatively associated with job satisfaction. Control Control has been found to correlate significantly with all three categories of job strains (Jex and Beehr, 1991). Spector (1986) showed the mean correlations across studies of relations between control and job satisfaction. Spector, P.E.

(1970), Need gratification theory: A theoretical reformulation of job satisfaction/dissatisfaction and job motivation. Journal of Applied Psychology, 54, 87-94. 2.3.2 The Consequences of Job Satisfaction and Dissatisfaction There are many positive or negative outcomes that relate to job satisfaction or dissatisfaction. These include not only work variables such as job performance and turnover but also non-work variables such as health and life satisfaction. Job Performance In fact, a large body of research shows that the relationship between satisfaction and performance is positive but usually very low and often inconsistent (Iaffaldano and Muchinsky, 1985). Why is this correlation between job attitudes and job behavior so low? Intuition suggests that we might work harder to pay back the organization for a satisfying job. However, intuition also suggests that we might be so busy enjoying our satisfying job that we have little time to be productive. For example, satisfying coworkers and a pleasant superior might lead us to devote more time to social interactions than to work. These contradictory intuitions provoke suspicion that the satisfaction causes performance might be incorrect. Iaffaldano, M.T. and Muchinsky, P.M. (1985), Jo satisfaction and job performance: A meta-analysis. Psychological Bulletin, 97, 251-273. Organizational Citizenship Behavior Organizational citizenship behavior (OCB) is behavior by an employee intended to help coworkers or the organization that contributes to organizational effectiveness (Organ, 1988; Schnake, 1991). Schnake (1991) hypothesized that OCB is caused by good treatment from the supervisor and by job satisfaction. In fact, job satisfaction and OCB have been found to intercorrelate (Becker and Billings, 1993; Farh, Podsakoff and Organ, 1990) Withdrawal Behavior Many theories hypothesize that people who dislike their jobs will avoid them, either permanently by quitting or temporarily by being absent or coming in late. Absence is a phenomenon that can reduce organizational effectiveness and efficiency by increasing labour costs. On many jobs, floaters or substitutes are required for each absent employee. The employee might continue to get paid, resulting in increased costs to pay substitutes. Where absence rates among employees is high, the costs can be quite high. Not surprisingly, organizations are concerned about absence. Theories of absence hypothesize that job satisfaction plays a critical role in an employees decision to be absent (Steers and Rhodes, 1987). People who dislike their jobs should be expected to avoid coming to work. On the other hand, most theories of turnover view turnover as the result of employee job dissatisfaction (Bluedorn, 1982; Mobley, Griffeth, Hand and Meglino, 1979). People who dislike their jobs will try to fin d alternative employment. Studies have been consistently in showing a correlation between job satisfaction and turnover (Crampton and Wagner, 1994; Hulin, Roznowski and Hachiya, 1985). Furthermore, it seems certain that this correlation is causal job dissatisfaction leads to turnover. Models of turnover place job satisfaction in the center of a complex process that involves factors both inside and outside of the employing organization. Figure 2-2 is a simplified model that shows how this process might work. Characteristics of the individual combine with characteristics of the job environment in determining level of job satisfaction. If the job satisfaction level is sufficiently low, the person will develop a behavioral intention to quit the job. That intention may lead to job search activities, which if successful will lead to turnover. Alternate employment opportunities are important because a person is not likely to quit without another job offer. Figure 2-2 Model of Employee Turnover as a Function of Job Satisfaction and Unemployment Rate Organization Factors Person Factors Job Satisfaction Intent to quit Search Behavior Turnover Availability of Alternatives Source: Spector, 1997 Burnout Burnout is a distressed emotional/psychological state experienced on the job. Where job satisfaction is an attitudinal response, burnout is more of an emotional response to the job. Burnout theory proposes that a person who is in a state of burnout experiences symptoms of emotional exhaustion and low work motivation, not unlike depression. Burnout correlates significantly with job satisfaction in that dissatisfied employees are likely to report high levels of burnout (Bacharach, Bamberger and Conley, 1991; Shirom, 1989). Physical Health and Psychological Well-Being Concerns have been raised that both physical and psychological health might be influenced by job attitudes. Individuals who dislike their jobs could experience adverse health outcomes. These outcomes include both physical symptoms and psychological problems (Spector, 1997). It has also been suggested that job dissatisfaction results in a shortened lifespan (Palmore, 1969). Many studies have been shown a link between health and job satisfaction. For example, researchers have reported significant correlations between job satisfaction and physical or psychosomatic symptoms, such as headache and upset stomach (Begley and Czajka, 1993; Fox, Dwyer and Ganster, 1993; Lee, Ashford and Bobko, 1990; O Driscoll and Beehr, 1994). Job dissatisfaction has also been found to be associated with emotional stated of anxiety (Jex and Gudanowski, 1992; Spector et al., 1988) and depression (Bluen, Barling and Burns, 1990; Schauboeck et al., 1992). Counterproductive Behavior Counterproductive behavior includes aggression against coworkers, aggression against the employer, sabotage and left (Spector, 1997). These behaviors have many causes, but often, they are associated with dissatisfaction and frustration at work. Chen and Spector (1992) found that job satisfaction correlated significantly with employee reports of engaging in aggression against others, hostility toward others, sabotage, and theft at work. Keenan and Newton (1984) found a relation between experiencing feelings of hostility at work and job satisfaction as well. Dissatisfied employees are more likely than their satisfied counterparts to engage in all of these behaviors. Life Satisfaction The research suggests that feelings in one area of life affect feelings in other areas. A person who is satisfied on the job is likely to be satisfied with life in general (Weaver, 1987). Studies consistently find that job satisfaction and life satisfaction are moderately and positively correlated (Judge and Watanabe, 1993; Lance, Lautenschlager, Sloan and Varca, 1989; Schaubroeck et al., 1992; Weaver, 1987). 2.4 Employee Satisfaction and Organizational Performance Organizational performance is a multidimensional concept. As illustrated by the list of thirty criterion measures identified by Cambell (1997). Performance is measured in terms of output (inappropriately referred to as productivity in the table) and outcome, profit, internal process and procedures, organizational structures, employee attitudes, organizational responsiveness to the environment and so on. More recently, one approach to measure organizational performance has become popular. This approach attempts to capture some of the contradictory nature of organizational performance is termed the balanced scorecard (Kaplan and Norton, 1992, 1993, 1996). This aims to measure performance in terms of four sets of indicators, each taking a different perspective (Kaplan and Norton 1996:76): Financial: to succeed financially, how should we appear to our shareholders? Customer: to achieve our vision, how should we appear to our customers? Internal business process: to satisfy our shareholders and customers, what business processes must we excel at? Learning and growth: to achieve our vision, how will we sustain our ability to change and improve? Therefore, about the relationship between employee satisfaction and organizational performance, the service-profit chain concept supported that there are direct relationships between profitability, customer loyalty, and employee satisfaction, loyalty, and productivity (Heskett et al. 1994). Moreover, a study conducted by a national retailer found that a happy employee will stick with the company, give better service to the customer and recommend company products to others (Wall Street Journal July 22, 1998). Other study of the 100 Best Companies to Work For finds that the companies with the most satisfied employees had an above-average annual return to shareholders (Fortune December 1, 1998). A Gallup study finds positive correlation between employee satisfaction and financial performance (Economist August 8, 1998). What is more, there are many studies about different industries also approved that the employee satisfaction correlated with organizational performance. Such as Kaplan an d Norton (1996) has found significant correlation between employee morale and customer satisfaction in an oil company. A survey of hospital employees finds significant correlations between nursing-staff satisfaction scores and patient loyalty (Atkins, Marshall and Javalgi 1996). Another correlational study using data collected for 298 public schools finds support for the link between satisfaction levels of teachers and school performance (Ostroff 1992). Thus, according to the previous literature, employs satisfaction is correlated to customer loyalty, financial performance, which in turn, affects the organizational performance.

The Omnivoreââ¬â¢s Dilemma: A Natural History of Four Meals by Michael Poll
The Omnivoreââ¬â¢s Dilemma: A Natural History of Four Meals by Michael Pollan, was a great read. I came into the adventure without much background regarding what kind of book it was going to be, and to my astonishment it was more of an educational journey than pages of force-fed beliefs. Michael Pollan has a writing style that is both loose and intriguing and really kept my attention throughout. Having already read extensively concerning human nutrition and food, I am usually skeptical when beginning such reads as this one, but I was very surprised that Mr. Pollan was very objective, in that this was seemingly a field trip and journey from environment to plate. I will begin this report with a summary of this great book and delve deeper into the thoughts that the literary family has of it. I will then go on to explain its importance in the development of environmental policy and impact, and end with my thoughts regarding the material and the interaction among social and environmental values and impacts presented by the author Michael Pollan. Summary The book begins with the question of ââ¬Å"What should we have for dinner?â⬠and stands to answer that question the rest of the way. Speaking directly of Americans, Pollan explains in-depth how the Nation tends to jump from fad to fad, first being afraid of carbohydrates, and then switching to fats, and so on. He goes on to explain where this thought process might have come from with the history of the Carter administration in 1977, as dietary goals were issued and the red meat lovers of America were warned to cut back. From that time on it has been an ever-changing lipo-, carbo-, phobia, with a cycle of weight loss and gain. With this question at hand, Michael Pollan begins to dive de... ...ormative history as he travels from the cornfields of Iowa, to the feedlot, to the forest floor in search of chanterelles, and then coming full circle to the dinner table. The information given is not always pleasant, but it is necessary for an informed eater in America to be aware of. The effects of knowing can cause us to be more responsible in what we are purchasing at the grocery store (and essentially voting for). He shows that making the correct decision to the question ââ¬Å"What should we have for dinner?â⬠can also be the choice that tastes the best and is the best for you. Works Cited Kamp, D.

Factors That Affect the Rate of Reaction of Peroxidase
Factors that Affect the Rate of Reaction of Peroxidase Purpose: To determine the effect of various factors on the rate of reaction between an enzyme and its substrate, and also to determine the optimal ranges under which the enzyme activity is maximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the enzyme is less denatured when it reaches the preferred pH level, and after this it will decrease because the active site will change in shape and it will no longer accept substrates. Temperature factor prediction: I predict as the temperature increases, the enzyme activities will increase because there is more energy to speed up the reaction until it reaches the optimum temperature range (room temperature which is about 20 à °C), and after that the enzyme activities will decrease because of denature of the enzymes (cause changes to active site that will no longer fit substrate) Concentration of enzymes prediction: I predict that as the concentration of enzyme increases, so the enzyme activities will increase because there is more enzyme to react with the substrates however when enzymes get saturated, the reaction will come to a plateau because eventually all the substrates will have enzymes to react with, and any extra will have no effect on the reaction whatsoever. I predict alcohol is an inhibitor of Peroxidase because alcohol when alcohol bind to the allosteric site it changes the active site shape of the enzymes thus deactivating enzymatic activities I predict salt is an activator of Peroxidase because salt contains Na ions which attaches to the allosteric site changing the shape of the enzyme to fit a substrate.

Knowledge and Understanding (Concept Analysis): Enzymes are made of protein, depending on the structure of the amino acid, and the hydrogen and ionic bonds is what makes the difference between the two enzymes (Catalase and Peroxidase). It seems to be that Catalase has stronger hydrogen and ionic bonds than Peroxidase and thatââ¬â¢s why it can withstand more temperature before itââ¬â¢s denatured. Conclusion: My experiment results agrees with my hypothesis. According to the data tables I have created, you notice that the enzymatic reaction (amount of bubbles) first increases starting from 15à °C then it starts to go down when it reaches over 25à °C (this matches with my first prediction on the effect of temperature on Peroxidase) Starting from pH 3 to pH 7, the reaction increases then it decreases after pH 7 (this matches with second prediction) Starting from low concentration, we get less reaction then it increases gradually (this matches with my third prediction)

History of Life Through Time Essay
1. The website shows the basic phylogeny of the three main lineages of life forms. They are ââ¬Å"Archaea,â⬠ââ¬Å"Eubacteria,â⬠and ââ¬Å"Eukaryotes. â⬠It also shows ââ¬Å"Virusesâ⬠outside of the tree, with a question mark indicating that its place in the tree is undetermined, if it belongs in the tree at all. 2. This site attempts to show the two alternative phylogenies of the major lineages of life forms. The ââ¬Å"archaea treeâ⬠distinguishes two variations of archaea, and shows that archaea are more closely related to eukaryotes than to eubacteria. In the ââ¬Å"eocyte tree,â⬠archaea are not specified at all, but eukaryotes are shown as most closely related to crenarchaeota-eocytes, which was a derivation of archaea in the previous tree. 3. Viruses are not listed in these two phylogenies because they are not proven to be actual life forms. Where archaea, eubacteria and eukaryotes are classified as ââ¬Å"life formsâ⬠due to their ability to transfer genes, viruses have not been determined to be living. They are therefore not included on these two phylogenetic trees. At the other website, , a detailed phylogeny of the Eukaryotes is provided. From this it is evident that Fungi are more closely related to Animalia than to Plantae. 5. Both sites show that the major life classifications are ââ¬Å"Bacteria,â⬠ââ¬Å"Eukaryotes,â⬠and ââ¬Å"Archaea. â⬠The ââ¬Å"Tree of Lifeâ⬠site shows the alternatives to how closely the lineages are related, giving two examples of how the three domains may be nested within each other instead of being derived equally. The University of California site breaks down the systematics of each domain separately and more specifically, leaving the three domains as separate entities entirely.

The Benefits of a Standing Desk and Risks of Sitting
The Benefits of a Standing Desk and Risks of Sitting Standing desks offer many benefits for your health and ergonomics. Break free from the chains of sitting at a desk and stand up for yourself and your health. Health Benefits of a Standing Desk The first major benefit of using a standing desk is avoiding all of the negatives that make sitting at a desk bad for you! Sitting for long periods of time causes metabolic issuesââ¬âyou dont produce chemicals necessary for processing sugars and fats, and your circulation suffers. Your skeleton and muscles form a reactive frame for your body which wants to move and respond to outside forces. Additionally, your muscles need to regularly flex to support healthy functions and chemical production. Standing allows your body to adjust and move easily, flexing your muscles continuously. It also keeps your blood circulating well. Movement regulates your blood sugar and keeps your blood pressure lower. And this lets you live longer! Risks of Sitting Sitting increases your chances of developing diabetes, cardiovascular disease, and blood clots or thrombosis. Studies have shown some dramatic effects of sitting for long periods of time. Those who sit a lot are 54 percent more likely to have a heart attack. Men who sit more than six hours a day have a 20 percent higher mortality rate; women have a 40 percent higher mortality rate. If you sit for more than 23 hours a week, you are 64 percent more likely to die from heart disease. In addition, studies have also shown that regular exercise does not counteract the effects of prolonged sitting. The only way to reduce or eliminate the negative impact of prolonged sitting is to not do it. Working at a standing desk will accomplish that for most people. Another benefit of a standing desk is that you burn more calories throughout the day. That will help with weight loss or maintain a healthy weight. Standing while working will burn one-third more calories than sitting will, which could account for an additional 500 calories burned in a day. Standing Can Reduce Pain There is anecdotal and scientific evidence to show that standing while working will alleviate back pain and other repetitive stress injuries. The problem usually comes from not using your back enough. When you sit, you dont hold your upper body with your muscles; rather, you let the chair hold you. This leads significant compression within the chest and abdominal cavities, slouching of the shoulders and rolling of the spine. These are classic causes of repetitive stress injuries and back pain. Working at a standing desk will keep your core and back muscles engaged throughout the day and improve your posture. Mental Benefits of Standing Another benefit of a standing desk is an increase in your focus, alertness, and activity level. When standing, it is easier to release restless energy. Combine that with the good circulation, stable blood sugar, and an active metabolism, and it is easier to focus on the task at hand. Standing while working will burn one-third more calories. Many authors and statesmen throughout the centuries who swear by working at a standing desk have claimed that it helps get the creative juices flowing. It also fights fatigue and improves lethargy. While this may sound like a contradiction, it is not. Standing while working helps fight off the naturally occurring slumps and bouts of fatigue that often happen mid-morning or early afternoon. Those are often related to metabolic drops after meals are processed by the body. Keeping your blood sugar level helps avoid those. Staying active and releasing restless energy also promotes a satisfying tiredness when it is time to sleep. Your mind isnt racing and your body is ready to rest.
