Lab Report Respiration Essay Example

Lab Report Respiration Paper After this period of exercise the same individual squeezed the litheness as many times as possible within one minute and the results were recorded. At least 10 minutes later, a second trial was completed using the same exact steps, also recording data. These steps were done with 4 subjects separately. In this experiment the independent variable was the prior exercise and the dependent variable was the amount of times the clothespin was squeezed. The constants in this experiment included the amount of exercise, the time allotted to each individual to squeeze the clothespin and similar clothespins. Results: Graph 1 This graph shows the differences in averages of the number of times the clothespin was squeezed with and without prior exercise. Table 1 This table shows the data collected from each individual person. The data includes two trials of squeezing the clothespin in a minute without prior exercise and two trials of squeezing the clothespin with prior exercise. The data shows that, on average, the individuals were able to squeeze the clothespin more exercise with prior exercise. Discussion: The data directly supports the hypothesis. With a small margin of error it is fair o state that, in fact, prior exercise increases the number of times individuals can squeeze a clothespin, on average. Both the averages and the sub-averages of squeezing the clothespin with prior exercise were greater than those without prior exercise. This is a valid conclusion because when individuals exercise their blood pumps more. This causes a larger circulation of oxygen and nutrients. Thus, with more nutrients and oxygen circulating through the working body cells of the finger, it will take less time for the body cells in the finger to tire out, as hey may have done without prior exercise.

The largest and most prevalent source of error was the counting of how many times the clothespin was squeezed in a minute. Even with the help of other group members, it was very difficult to count the number of times the clothespin was squeezed especially because it was averaging around 250 squeezes in a minute. Also as the clothespin was used more and more, it became worn down and perhaps became easier to squeeze, thus resulting in more squeezes after exercise. Some other confounding variables included the amount of exercise. If one of the individuals exercised with more determination or even with more force, it would be more likely to get their heart rate higher. Also some individuals may have eaten more energy efficient food and had gained more energy than other individuals. Another significant variable was the kind of exercise. If the type of exercise involved any of the muscles used in squeezing the clothespin, then it would be extremely detrimental to the results of the experiment. The goal of the exercise is not to tire out the muscles but rather to get the heart rate up. In a controlled laboratory there are several ways to prevent these errors and confounding variables. In order to count the clothespin squeezes accurately, one may attach a high tech counting device. This would greatly improve results. Also if there were a controlled exercise that involved none of the muscles used in the experiment it would eliminate several errors and confounding variables. Also to decrease error verbal, increasing sample size would have a substantial effect. Suggestions for further research: During this experiment several questions were left unanswered and provided suggestions for further research. One of these questions was if increased squeezing of the clothespin was correlated with an increase in heart rate in general. To test this one would have to test different ways of getting someones heart rate up such as exercise, scaring, and making them nervous, then make sure that the heart rates are the same, and finally test if the increased heart rate verbal allows that individual to squeeze the clothespin more, or if it is just after exercise. Another question that was left unanswered was whether a repetition of squeezing the clothespin over a series of months causes the individual to squeeze the clothespin more. To test this one would have to have a large amount of people squeeze clothespins for an allotted time every day for a month, or so. Then the tester would collect all the data and see whether there was an increase in the number of times the individuals were able to squeeze the clothespin within the allotted time.

Discuss the challenges and benefits involved in using a health Essay - 1

Discuss the challenges and benefits involved in using a health promotion approach to tackle the levels of depression experienced within the general population - Essay Example This has been majorly attributed to the fact that research undertaken among these professionals to facilitate the understanding of mental health issues differ with regard to the methodologies, theories and language used to undertake the study. Stakeholders such as psychologist, sociologists, non-governmental organizations and governments have developed and implemented various approaches directed towards reducing various health challenges that arise due to cognitive problems. The level of efficacy among these approaches differs to a great extent; however, some of these challenges have shown a great level of relationship. Another most obvious characteristic of these challenges is the fact that they have benefits and to some extent demerits. This discussion will focus on the various approaches that are used to promote mental health among different populace and their associated challenges as well as benefits, specifically those that are applied towards reducing problems caused by depression. Depression one of the most common mental health challenges that are in the contemporary society. Most psychologists have described depression as disorder that affects an individual’s moods by causing continuous feelings of sadness as well as loss of interests in various human activities (Aguirre, 2008). In addition, depression has been cited as mental health challenge that can also affect an individual’s physical capacities and emotions by creating variation in an individual’s mode of thinking and behavior (Aguirre, 2008). One of the most common approach to addressing various levels of depression as a mental health challenge is the application of the Public Health Approach. Specifically, this approach involves the application of medical and psychological strategies geared towards changing the behaviors, lifestyles and coping mechanisms to challenges caused by depression. Public health approaches are closely related with the reduction of depression as a major

Impacts of the metropolitan person of the rise of the post-modern Essay

Impacts of the metropolitan person of the rise of the post-modern urban condition - Essay Example Within the US, a range of regional planning processes have designed place-type models to help the public and policy makers during the patterning of redevelopment and urban expansion. These model place-types will ordinarily indicate the land use mixtures and the densities, and in some cases, street patterning and building forms. Through the proposals, decision-makers can estimate the environmental and transportation impacts of optional area place-type blends, using I-PLACE3S and GIS-based software. However, irrespective of new attention to large-scale urban design, some suburbanization histories and the classic examination of urban forms throughout history; the developments of urban expansion for cities in North America have not been charted out in a systematic way. This report will detail a study of the evolution of spatial developments across the Sacramento urban area, using GIS (Geographic Information Systems) software to map the growth and the changes that came with the growth. Ad ditional research from secondary sources will offer more information on the history of the urban area and the triggers of growth. The report aims to provide the morphological growth of the region, pointing out the full range of constructed landscapes created through its history, which will help in the management of urban growth. Related Literature The commonly available historical accounts of suburbanisation and urbanisation tend to emphasize the general aspects of growth, and the forces triggering urban development, compared to giving information on the systematic growth of urban forms. Most times, these accounts depict an impressive history, and may assume a normative outlook; Mumford’s â€Å"the City in History† of 1961 is among the iconic examples of both areas. The main focus of these accounts includes financial, cultural and the institutional factors that trigger growth. Others like Hall (2002) focus on the planning ideas and the visions of urban areas. Additiona lly, some scholars emphasize the urban histories of the urban areas, and many others have reviewed the historical account of certain cities (Abbott, 2008). Although, many of the works mentioned before focus on demographic, sociological and cultural change, some iconic planners, geographers and historians have directed more attention towards form. Through the analysis of official maps and designs, which are supported by other sources of graphic evidence, the information is used to offer information on the changes that have taken place in economic needs, cultural values and governmental purposes. Other accounts like Kostof (1992) focuses particular features of design of the city, throughout history, emphasizing on the reflection of purpose and meaning from patterns. Lynch (1981) pointed out the significance of different spatial aspects of a city, including edges, paths, nodes, districts, and grain, going further to explore the ways in which they affect the lives and the experiences of visitors and the residents of the region. Vance (1990) reviewed function and form in urban settlements in human history, directing special attention towards the stages of development, the location of cities and their connectivity – with reference to transportation and trade. Recent literature has been highly systematic in analyzing form, by developing models of form at

Meaning of supervision and my professional life Essay Example for Free

Meaning of supervision and my professional life Essay Instructional Supervision Instructional supervision is a very important concept which must be understood by all educators for the sake of achieving their teaching objectives. For this case, the process of instructional supervision must be applied for the sake of delivering effective instructions to the students. Supervision of instruction for example in England began as an external inspection where some people were appointed to go around the school to observe what the students were learning and what the teachers were teaching the students. The main aim of these supervisors was to ensure that the set curriculum was being followed and the students were actually being taught. On the other hand, in United States, supervision began in 1830’s after the formation of common schools. Initially, supervision in schools was undertaken by superintendents after the formation of city school system due to increased population in major cities. Later on, the role of supervision by superintendents became impossible as the number of schools increased. The role of supervision had to be delegated to the principal to oversee that the teachers we following the curriculum in their teaching. In order to promote growth of teachers and recognizing practice of supervisors time restrain, Sergiovanni and Starratt (1998), suggested that a supervisory system be created that would contain a number of processes of supervision even summative evaluation. The system was not to involve direct formal supervision every year for every teacher. This system was to evaluate the teachers within a period of three to five years. In this kind of evaluation, the teachers were to receive a variety of evaluation during the three or five years and finally be evaluated formally only once. Professional growth evidence is required during once-a-cycle formal evaluation. The work of supervision was also attempted to be opened at international involvement by Sergiovanni and Starratt. In a school setting, the principal has the overall responsibility of supervision of the whole school. For this case, he supervises, teachers, students and all the other staff working in the school that include: librarian, gardeners, drivers, cleaners etc. The supervision role is not an easy task especially of teachers and for this case, the principal has to carry out the exercise with intelligent and diplomacy. The teachers of course knows their role and they would feel not motivate if they see they are being supervised like factory workers. This would in turn kill their morale at work and finally they would not deliver the required knowledge to the students and the end result would mean that the teaching objectives will not be achieved. The principal on the other hand has a responsibility of supervising the work of the students and together with their behaviors. Students tend to acquire deviant behaviors from other students like smoking and unless this behavior is corrected at an early stage, the student will not concentrate in his learning. In some situation, the supervision of students gets out of hand as they tend to have acquired more serious behaviors such as carrying of weapons and may be killing of their fellow students. For this case, this becomes criminal offence and is not likely to be handled the principal. Principal should be very strict when it comes to discipline for the sake of ensuring that education objectives are achieved. Since the students are in a crucial stage of adolescent stage where influence of behavior is at high level hence their behaviors should supervised keenly. According to Glickman (1990), there are a number of supervisory approaches within clinical supervision structure. He developed a supervision model that provides theoretical framework that with four supervision approaches that would be found in supervision concept. These approaches are similar in the intended end goal but they differ differs slightly in the power and control that is accorded to the teacher. The four approaches are a follow: The first supervision approach is the nondirective supervision whereby the teacher has the freedom of formulating his own plan on the future development. In such a situation, the supervisor is there to give advice to the teacher when he comes up with his own ideas on the way forward. This kind of approach indeed motivates the teaching staff members as they feel they are in control with their undertakings. For this case it should be encourage at situations where the teachers are experienced in their work and they can work with little or no supervision. (Glickman, 1990) The other supervision approach is collaborative supervision. In this approach, the teacher and the supervisor do share idea before the supervisor makes decision on whatever decision he wants to make. This approach too is a good one also as the teachers feels motivated as they are consulted before any decision can be arrived at. For this case, the teachers contribute their ideas and the supervisor weighs various options before settling on the best idea that has been contributed by the teachers. By merely brainstorming of ideas, the approach is of much help for the sake of choosing the best approach to be used. For this case, this kind of approach should be encouraged at situation where teachers involved are experienced in their work. The third supervision approach is the directive informational approach. In this situation, the supervisor formulates the supervisor plan and it is the responsibility of the teacher to decide if he is going to follow the plan. In this kind of an approach, the teachers are not motivated with it as they feel they are not consulted before a decision is being made in their work. Although some of the approach since it consumes less time before it is formulated, majority of them especially the experienced ones feels that some ideas which are better are overlooked. In this kind of approach, the teachers are given an opportunity to follow or not to follow the approach directives. However, the approach is appropriate mostly to teacher who are not experienced or the novice teachers. Lastly is the directive control approach in which the teacher formulates the supervisory plan and expects are the teacher to follow it. For this case, the teachers have no alternative on whether to have another idea. They have to follow the supervisory plan that has been formulated by their supervisor. This approach however does not motivate the teachers as they are not given an opportunity to contribute their ideas toward formulation of a supervisory plan. For this case, they have to follow the directives as formulated by their supervisor. This approach is popular where the teachers being supervised are less experiences of novice. It is also very appropriate in situations whereby there is not time to gather in a meeting and brainstorm on the way forward as far as supervisory plan is concerned. Before the supervisor can know on which approach he should use, he should consider knowledge and experience of the teachers concerned before settling on the supervisory approach plan to use. The issue of responsibility and accountability should also be looked into in order to decide on the approach to use for the sake of at least motivate the teacher in their work. Motivation is the inner drive to do something, and unless the teachers have that inner drive to deliver knowledge to their students, teaching objectives might never be achieved Glickman (1990) asserts that collaborative approach is very popular among the teachers and they really enjoy their work if used. For this case, school principal should at least ensure they use this kind of an approach when they are formulating their supervisory plan to be applied in their school. There are three supervisor responsibilities that should be considered in the supervision process. They include: ? The Supervisor to carry our observations to both the teachers and students. ? The supervisor to give guidance and support to teachers and students. ? Lastly is for the supervisor to give feedback to the teachers. According to Knoll (1987), the information that a supervisor gather after carrying out a classroom observation is very important. He is able to have an access to a wide range of skills necessary for teaching which he can in turn share it with other teachers. The main aim of carrying out a classroom observation is to collect data that is necessary for carrying out an evaluative rating which is accurate. As far as supervision is concerned, guidance and support should be the main idea of supervision in the first place. Supervision is not done just to see whether teachers are following the curriculum or not and then note that one down, no. One should continuously offer guidance and support as he supervises. For this case, the supervisors are urged to make correction on the spot while carrying out their supervision roles in order for them to achieve their objectives. In order for teachers to improve on their areas of teaching, the supervisor must ensure that he gives feedback to them on the areas he has observed that would like to be improved. There would be no need of supervision if the teachers are not given the feedback as it is this feedback that they will know what areas they need to improve in while carrying out their duties. There is very big difference between evaluation and supervision though the two terms interrelates. Evaluation is the art of making judgment about the performance of a teacher. On the other hand, supervision is mere the art of ensuring that the teachers are following the laid down rules and regulation in their work. Evaluation comes after one has carried out an observation on the teachers. Appendix Literature Review Instructional supervision improves teaching performance if it is carried out in the manner that is desired by teacher. If the collaborative supervision approach is used according to Knoll (1987) is used, the teachers will be motivated in their work and the overall performance of the school will be felt. In his book Supervision for better instruction: Practical techniques for improving staff performance, Knoll (1987) asserts that teachers are motivated in their work of teaching when collaborative supervisory plan approach is applied in their supervision. Pfeiffer and Dunlap (1982) in their book Supervision of teachers: A guide to improving instruction asserts that teachers need to be motivated in their work for the sake of achieving their teaching objectives. Motivation can only be achieved if the supervisors uses collaborative supervisory plan in their work. On the other hand, Rettig (2000) in his journal Leslie’s lament: How can I make teachers’ supervision meaningful? asserts that unless guidance and support is given to teacher, there is no need of supervision in the first place. He further states that teachers should be given a feedback after they have been successfully evaluated by their supervisor in order for them to improve in their teaching. He concludes that teachers’ supervision will be meaningful after the guidance, support and feedback is given to teachers by their supervisors. References Bourisaw, D. M.

Windows 95 Beats Mac :: essays research papers

Windows 95 Beats Mac Over the years, there has been much argument over which computer platform to buy. The two contenders in theis competions have been the PC , with its Windows environment and the Macintosh. Now, with the successful release of Windows 95 for the PC, this has been the mjor argument for each side : hardware configuration, networking capabilities, and operating system. The first arguments to look at between the Pc and Mac platform has to do with hardware configuration. Before Windows 95, installing and configuring hardware was like pulling teeth. The instructions given to help install hardware were too complicated for the average user. There was also the issuer of compatibility between the large number of different hardware setups available in the PC world. Is a particular board going to work with my PC? With Windows 95, these problems were alleviated with plug and play technology. With plug and play compatible boards, the computer detects and configures the new board automatically. The operating system may recognize some hardware components on older PCs. Mac userw will claim that they always had the convenicnce of a plug and play system, ubt the difference shows in teh flexibility of the two systems. Another set of arguments Mac users use in favor of their sysstems over PCs is in multimedia and networking capabilities. Mac users gloat that the Mac has networking technology built in the system. Even if a user did not use it, the network is included with the system. They cited that for the PC users and Pc users hate the fact that they need to stick a card in their computers to communicate with any other computer. With Windows 95, the Mac network gloaters are silenced. Windows 95 included built-in network support. Any network will work properly. The Mac users also claim their systems have speech, telephony, and voice recognition, whereas the Pc user does not have. In truth, the promised building blocks for telephony control do not yet exist. I think the speech is not good point in the Mac.

Balanced Scorecard Essay

Introduction Performance management systems are often designed to enable organizations to plan, measure and control their performance, so that decisions, resources and activities can be better aligned with business strategies to achieve desired results and create shareholder value. The Balanced Scorecard is a performance tool using financial and nonfinancial measures. It provides an organization with ways to develop and evaluate strategic objectives and goals. For the past two decades, the Balanced Scorecard (BSC) has been proposed as an integrated framework for the implementation of financial and nonfinancial performance measures that helps organizations align their initiatives with the organization’s strategy (Kaplan ; Norton, 1992). The United States Postal Service delivers more mail to more addresses in a larger geographical area than any other post in the world. The Postal Service delivers to more than152 million homes, businesses and Post Office boxes in every state, city, town and borough in this country. Everyone living in the United States and its territories has access to postal products and services and pays the same postage regardless of their location (USPS, 2014). This paper will examine the effectiveness of the implementation of the balanced score card approach. Key Issues for Discussion Explain how the Voice of the Employee supports improved internal processes (Voice of the Business), and how the Voice of the Business supports customer satisfaction (Voice of the Customer). Employees have a huge impact on their organization’s financial results. When employees are empowered to make decisions they share information relating to the strategic processes and direction of that organization. When it comes to carrying out the message and mission of the organization the voice of the employee is very crucial. Through empowerment, the employees are able to create an opportunity to show management how they will apply the company vision to their daily task. The voice of the business relates to information derived from financial data. This data can be used to indentify weakness in certain market areas and the status of the research and development process. In order to move the organization forward or closer to its overall objectives, analyst must understand the relevance of the balanced scorecard process. The voice of the customer indentifies the needs of the customer which are keys to the strategy to defining which processes can be viewed as value added products or services. The customers are a continuous source of feedback both good and bad. Customer feedback can also provide new opportunities to identify and develop new products. Kaplan and Norton advocated a well-connected map ping that leads from an organization’s main strategy to the four perspectives of the balanced scorecard: Financial, Customer Satisfaction, Internal Process, and Learning and Growth. Each element works to support the strategic objectives in a linked process. Customer satisfaction leads to the desired financial outcome, which in the case of the Postal Service is sufficient revenue to support the universal delivery service mission (Evans, Lindsay, 2011). While Figure 8. 14 shows only representative measures associated with the balanced scorecard, suggest some other measures that might be included using your knowledge of postal operations. Based on my personal experience and knowledge of the United States Postal Service, I would suggest that the organization add some additional measures to it balanced scorecard. The organization should measure customer complaints relating to package handling and damaged goods. Damaged packages generally lead to claims brought forward by customers which is certainly a value associated with it that should be tracked and measured. The organization should also measure and analyze the effects of the employee turnover rate. Employee replacement cost can have a huge affect on the financial element. Cost associated with the orientation and training of a new employee as well as the cost associated with employee separation can have an effect on the bottom-line. Advantages and Disadvantages of Using a Balanced Scorecard Some organizations have a difficult time establishing a process that can translate its strategic vision into concrete goals and actions. There are clearly some beneficial advantages to applying the balanced scorecard approach. Some of these benefits include gaining a cross organizational team that will open channels of communications. The company will have enthusiastic people who are focused on carrying out the organization’s mission and commitment to quality. Also, the company will gain a unique competitive advantage relating to reduce time frames, improved decisions and better solutions. Most importantly, initiatives are continually measured and evaluated against industry standards. There can be some disadvantages as well. The balanced scorecard takes a lot of planning and forethought. Defining clearly stated objectives and setting goals are crucial to the process. There can be resistance from employees or even management. Some individuals may see the implementation as a threat or indication of a lack of performance on their part. While the balanced scorecard gives an extensive overview of the organization’s performance, it does not give recommendations regarding how to resolve discovered problem performance areas. Conclusion The case study involving the United States Postal Service presents evidence that the balanced scorecard approach can have a positive effect on an organizations overall performance. If integrated successfully, the balance scorecard will be a tool that ensures clarity and consistency across all departments or individuals involved. Solving quality management issues rely on the right approach and planning. Understanding the importance of the linkage among all four of the balanced scorecard is crucial to its success. Special attention should be given to the proper implementation and cultivation of intangible assets relating to learning and growth. The USPS has improved its service and has increased customer satisfaction. First-class mail performance has improved to over 95 percent of overnight mail being delivered on time, with improvements in other categories of first-class mail (Evans, Lindsay, 2011).
