HR MANAGEMENT Term Paper Example | Topics and Well Written Essays - 750 words

HR MANAGEMENT - Term Paper Example n is defined as a state arising in processes that are internal and external to the individual where the person perceives that it is appropriate to pursue a certain course of action directed at achieving a specified outcome and the person involved pursues that outcome with vigour and persistence (Robinson, 208). The employees have their own needs hence the plan to interview them is seen as viable so as to be in a position to get their views and ideas about what they think should be incorporated in their work in order to motivate them. The HR department will be in a position to use the responses from the interviews to create a master plan of the following: The plan to rebrand the HR department will be implemented over a period of time and this will be done in stages. The HR manager will be responsible for implementing that action plan and he will get some input from the other members from the same department. All the responses from the interviewees will be taken into consideration so as to be in a position to come up with a sound policy document that can improve the performance of the HR department as well as to improve the morale of the workers. The employees have to be treated as valuable assets to the company and this is the reason why we have to get their views. The interview questions are designed in such a way that they are short and they enable the interviewee to give short and succinct answers. Therefore, it is anticipated that an interview with one employee will take approximately 15 minutes. These interviews are expected to be conducted in five working days so as to enable the department to perform other pertinent tasks in its operations. We anticipate that at least two hours per day from Monday to Friday (8 am to 10am) will be devoted to these interviews and they will be conducted in the boardroom. After conducting the interviews with all the employees, the HR manager will need at least three days to go through the responses by the interviews so as to

Thermal Solutions to Reduce Electricity Costs

Thermal Solutions to Reduce Electricity Costs Executive summary This report investigates and analyses the thermal solutions to reduce the electricity cost for senior school at St Aidan’s Anglican Girls’ School. Approaches of analysis include calculating energy loss, thermal current and comparing current costs and revised costs, as well as the long-term (each term and annual) prediction for power consumption. The annual electricity cost is predicted to be $23064.56. All calculations can be found in the Appendix. Results from calculated data show that 29.09% of the power consumption can be reduced by replacing 36 W lights from 18 W tube light bulbs ($4.90 for two tubes, $44.10 overall) and installing the Hampton thermal curtains ($276 in total) with pelmet boxes ($183) of five years life expectancy. Hence, they are suggested to renovate every five years to maintain the efficiency of thermal curtains. Although these installations will need $503.10 initially, the payback will begin from the 7th month. This report evaluates that the current setting of the classroom in senior school can be altered to protect the environment and minimise electricity costs. Therefore, there are some recommendations: Install the Hampton thermal curtains with pelmet boxes Thermal curtains should be shut all the time in order to achieve the revised cost Small technology devices (e.g. projector, printer, iron and hot glue guns) usage should be minimised to reduce power usage (e.g. turn them off instead of stand-by when not using) There are some weaknesses of the report: Thermal current of furniture in the room is not considered. Monthly temperature data are not exact results, they are based on past average temperature data. Number of classrooms are an approximation instead of counting due to variation in classroom setting (e.g. one air-conditioner, more or less lights, fridge) Key assumptions The power is assumed to be used only on schooldays. The energy loss from the recorded data (the energy required to cool down) is assumed to be the same every day. The room is assumed to be a closed system, so the thermal current of windows is equivalent to the power usage of both air-conditionings. Power Usage Analysis Introduction Thermal (heat) energy always tends to transfer from one hot space spreading to colder surroundings space by conduction, convection and radiation (Cambridge University Press, 2014) and its flow is affected by the temperature difference. Thermal current () is the rate at which heat energy passes through a material, which is calculated as . The thermal conductivity (k) is a measure of how well the material transfers heat; lower values of conductivity indicate better insulating material. Thermal insulators such as thermal curtains and double glazing windows are commonly used in homes or buildings to maintain constant room temperature by prevention of convection current and minimise energy usage. This report will investigate, analyse and recommend thermal solutions for the school to reduce electricity usage and environmental benefits. Investigation and discussion Note: All data refers to Appendix – Calculation The data was collected by using Sparkvue temperature sensors connected to a computer. The first 30 minutes of the data was disregarded due to the sensor being exposed to direct sunlight, leading to the extremely high temperature (especially the peak at 3:19pm at 47.4Â °C) at the beginning of the data (Graph 1). Through analysis and calculations of the data, the internal temperature change had a positive gradient (between 5:04pm and 6:04pm) which indicated the room was gaining energy as the air-conditioning turned off (347.08 W). Current power usage During schooldays, 18 lights were used 1 hour 43 minutes per day and two air-conditionings were used 10 hours daily on average. The lights were found to consume a relatively low amount of energy of 1.11 kWh daily. Since the room was assumed to be a closed system, theoretically, the thermal current of the windows (137.14 kWh) should be equivalent to the power usage of air-conditioners. However, due to the information written on the air-conditioning was its upper most power usage, they would not be equal. In fact, the calculated consumption (Table 2) was less than the given data, which indicated the difference in power usage could be attributed to dissipation through the walls, floors and doors openings. Moreover, the total consumption (139.52 kWh) included the power consumption of lights and technology devices in the room to achieve higher accuracy. Thermal solutions Thermal solutions are reasonable and beneficial to diminish power consumption. The 36 W light bulbs can be replaced by 18 W lights, which each consume 0.56 kWh daily. Furthermore, thermal curtains are the most common thermal products, because more internal thermal convection current will be blocked, especially when the curtains are extended so that it reaches the floor. This would prevent the convection current and reduce energy flow into the room (Figure 9). Double and triple glazing of windows are commonly used as well, due to vacuum between glass panes eliminating losses by conduction and convection; however, installation is expensive, so thermal curtains are the most economic thermodynamic barriers to use in order to reduce the energy usage. Figure 9 – No gap (Rogers A, 2011) From researching thermal curtains, the Hampton thermal curtain is thermal coated which reduces a maximum of 25% energy loss (Energy.GOV, 2012). Only the front windows have contact with direct sunlight; others are all under shelter, so thermal curtains will only cover these. Hence, the Hampton thermal curtain is suggested to be installed for energy reduction, costing $276 in total. Pelmet boxes cost $183 overall, because the side of the front windows have a length of 6.02 m each, it would be reasonable to get two 6.10 m pelmet box on each side(some space for the curtain rod). The life expectancy of thermal curtains is usually five years; it is reasonable for the school to renovate new curtains every five years. It can be seen from Graph 2 that the costs maintain the same and increases by another full cost of $503.1 after renovating at the end of each five year cycle. Furthermore, the power usage with thermal solutions is calculated to be 97.25 kWh, having a 29.09% difference compared with the current settings. CBA – Cost Benefit Analysis The CBA graph (Graph 3) shows the current cost model and revised cost model accumulating over time. The break-even point occurs in the 7th month and when the current cost is approximately equivalent to the revised cost at $1661.8 and $1654.3, the current cost will exceed the revised cost. According to the CPI in Queensland has been fluctuating from 2007 to 2012 (Figure 10), which may continue changing in the next few years. By considering a long-term situation, Graph 4 illustrates an example of revised cost will increase every five years due to renovation of curtains, whilst maintaining a smaller rate of power consumption than the current cost. The power consumption for each term is calculated (Table 3-6) and used to investigate the annual revised cost of $23064.56 and 28.98% of electricity cost will be reduced from current cost in the senior school. If the electricity price increases 5% for both peak and off-peak hours, the trend would stay the same as the current cost has a higher gradient than the revised cost (Graph 4) and the fluctuation has an impact on the overall costs. (Australian Government, 2015) Figure 10 – CPI Annual Change Brisbane Recommendations The ultimate goal of diminishing the energy usage is to protect our environment and minimise energy consumption. Therefore: Thermal curtains with pelmet boxes and light bulbs should be installed. Curtains should be shut all the time in order to achieve the revised cost. It would be the most economical way if all small technology devices are not used at all (e.g. projector, printer, iron and hot glue guns). In conclusion, after installing the thermal solutions it is predicted to spend $23064.56 annually in the senior school, and results in saving approximately $13072 on power usage when all assumptions are valid, which will therefore reduce environment impact.

The Importance of Books :: Teaching Education Essays

The Importance of Books Book have been a part of my life since the beginning. My mother once told me her and our neighbor would sit together and read to me and the other woman’s baby, who was later to become my childhood best friend. I didn’t start reading Wharton and Steinbeck until much later, but we have to start somewhere. Before knowing how to read, my mother and father would read to me a book from my endless number of â€Å"The Bearnstein Bears† books. Every book had a lesson. I think that having been read to every night and being explained some of the words and their techniques of why they are the way they are, helped plow my way in favor of learning to reading in school. When it came to reading â€Å"Look at Spot† and those other memorable 2-3 worded pages that made up a story, I was always ahead and frequently help my teacher with her work rather then practicing reading with the rest of my class. Now being read to before bed time became reading to me mother and father. My most sentimental memory of being read to be when my father went overseas to be in Desert Storm, he recording himself reading a countless number of books so he could still read to me even though he was a lot of miles away. It was one of few moments I can really remember about him in my childhood. He was always aroun d when he could be but when he wasn’t there he was dreadfully far away. When I started to read for myself, the books would consist of Amelia Badelia, Peanut, Butter, and Jelly, and any book authored by Shell Silverstein. Eventually in school we were being assigned to read books for class and for Accelerated Reader. AR book are certain books that contain a test you take and the difficulty of the book corresponds with the number of point receives with each correct answer given. After, about, every six weeks there is an AR prize cart. This system works like Chucky Cheeses’ or Peter Piper Pizza. You could wait to â€Å"spend† your points until the end and receive a really expenditure and remarkable prize. It encouraged others and me to read more and to read the more difficult books.

Succubus Blues EPILOGUE

â€Å"Casey's out sick,† Paige told me briskly, putting on her coat. â€Å"So you'll probably have to cover for her on the registers.† â€Å"It's no problem.† I leaned against her office wall. â€Å"Keeps things interesting, you know?† Pausing, she gave me a brief smile. â€Å"I really appreciate you coming in like this – on such short notice.† She patted her stomach absentmindedly. â€Å"I'm sure it's nothing, but I've had this pain all day – â€Å" â€Å"No, it's fine. Go. You have to take care of yourself. You have to take care of both of you.† She smiled at me again, picking up her purse and walking to the door. â€Å"Doug's skulking around here somewhere if you need help, so make him do it. Hmm†¦ there was one other thing I needed to tell you†¦ Oh yeah – there's something for you in your office. I left it on your chair.† Butterflies shot through my stomach at her words. â€Å"W-what is it?† â€Å"You'll have to see. I've got to go.† I followed Paige out of her office and turned uncertainly into my own. The last thing left on my chair had been an envelope from Roman, one more piece in his twisted game of love and hate. Oh God, I thought. I knew it wouldn't be as easy as Carter had said. Roman's back, starting it all up again, waiting for me to – I stared, swallowing a gasp. The Glasgow Pact sat on my chair. Gingerly, I picked up the book, handling it like fine china. It was my copy, the one I had given Seth to sign over a month ago. I'd forgotten all about it. Opening up the inside cover, I saw lavender rose petals fall out. There were only a handful of them, but they were more precious to me than any of the bouquets I'd received this month. Trying to catch them, I read: To Thetis, Long overdue, I know, but very often the things we most desire come only after much patience and struggle. That is a human truth, I think. Even Peleus knew that. – Seth â€Å"He's back, you know.† â€Å"Huh?† I looked up from the baffling inscription to see Doug leaning against the doorframe. He nodded toward my book. â€Å"Mortensen. He's up in the cafe again, typing away as usual.† I closed the book, holding it tightly with both hands. â€Å"Doug†¦ are you up on your Greek mythology?† He snorted. â€Å"Don't insult me, Kincaid.† † Thetisand Peleus†¦ they were Achilles' parents, right?† â€Å"Indeed they were,† he told me, smug with the confidence of his area of expertise. For my part, I was simply puzzled. I didn't really get the inscription or understand why Seth would reference the Trojan War's greatest warrior. â€Å"Do you know the rest?† Doug asked me expectantly. â€Å"What? That Achilles was a dysfunctional psychopath? Yeah, I know that.† â€Å"Well, yeah, everyone knows that. I mean the really cool part. About Thetis and Peleus.† I shook my head, and he continued, professor-like, † Thetiswas a sea nymph, and Peleus was a mortal who loved her. Only, when he went to woo her, she was a real bitch about it.† â€Å"How so?† â€Å"She was a shape-shifter.† I nearly dropped the book. â€Å"What?† Doug nodded. â€Å"He approached her, and she turned into all sorts of shit to scare him off – wild animals, forces of nature, monsters, whatever.† â€Å"What†¦what'd he do?† â€Å"He held on. Grabbed her and wouldn't let go through all of those terrible transformations. No matter what she turned into, he just held on.† â€Å"Then what?† I could barely hear my own voice. â€Å"She finally turned back into a woman and stayed a woman. Then they got married.† I had stopped breathing somewhere around the word â€Å"shape-shifter.† Still clutching the book, I stared off into space, a great winged feeling swelling in my chest. â€Å"You all right, Kincaid? Christ, you've been weird lately.† I blinked, tuning back in to reality. The feeling in my chest burst out, launching into glorious flight. I started breathing again. â€Å"Yeah. Sorry. I've just had a lot on my mind.† Forcing levity, I added, â€Å"I'll do my best not to be too weird from now on.† Doug looked relieved. â€Å"Coming from you, that might be a long shot, but here's to hoping.† â€Å"Yes,† I agreed, smiling. â€Å"Here's to hoping.†

Natural sciences Essay

Knowledge involves acquaintance with truth, principles or facts as with a certain subject or a branch of learning. People have various perceptive of knowledge. There are those who belief that knowledge is found in many forms which must be proven with evidence. It is possible to doubt everything that exist because it is a misconception or it may be seen as an illusion. Doubt is important in knowledge because learning through from the senses or through the senses can be deceptive. For example, senses can deceive because one may smell something sweet and senses deceive that it is going to have sweet taste. However, this is wrong because not everything that smells sweet taste sweet. Dreams are also deceptive as they are just false delusions because occasionally when one is asleep one is deceived by the illusions in dreams. These are just ways that knowledge through the senses can deceive. Therefore, it becomes necessary to doubt everything so that one can get the true knowledge. So as the proverb hold doubt is key to knowledge. Knowledge creates doubt and doubt pave way for gaining more knowledge. If its is not for doubt then there would be no knowledge or the knowledge that would be available would be one that is not complete knowledge (Urdahl, pg 27-29). In natural sciences, scientists have a lot of experience with doubt and uncertainty. This is experience that is very necessary in gaining knowledge in natural sciences. When one does not know the answer to a problem then this can be termed as ignorance. Then one has a hunch as to what the results are, for example, of an experiment, then it means that one has uncertainty. When one is darned sure of what the result would be then it means that one has some doubt. Therefore, it is paramount important that in order to have progress it is important to recognize the ignorance we have in natural sciences and leave room for doubt. This is because scientific knowledge is a body of statements, which have varying degrees of certainty. The degrees vary from being unsure, nearly sure and none absolutely certain. Doubt is a good thing in natural science because if one knows the answer or thinks that one knows the answer then it becomes easy to fail to seek more knowledge about that particular subject. Doubt helps to come out of that emotional attachment that people have in certain beliefs or from the theory of determinism. Example of areas where doubt has assisted in gaining and verifying knowledge is in the assumptions in relativity that inertial mass and gravitational mass are equal. In order to show that they are not the model has to be revised. Scientists have engaged in refining their ability to measure the two. It is the doubt that has developed in this area that has made the scientist revise this model until they have realized that inertial mass and gravitational mass are different at finer degrees. Therefore, they doubt has made it known that the two are not equivalent as has been held in the past. In this case, it is not that the same experiment is repeated but the real key to this is to look at the statements and test if they have been examined to the extent that they should. Doubt allow the use of new tools in scientific experiments which allow new discoveries which do away with the old ideas or theories. Science in this case becomes a process of doubt. Natural scientists are always nor sure and this is the reason as to why they repeat the steps in experiments in order to make sure that it is right. Another area where doubt has necessitated growth of knowledge is in the evolution theory. At the beginning people had strong belief that creation theory was the one that provided call the knowledge about the evolution of human being. However, as knowledge grew people started to doubt some aspects of the evolution theory and developed other theories such as the Darwinian theory of evolution. This is a theory which resulted out f the doubts about some of the aspects of the former theory. This is not the end theory because doubts in some aspects of the evolutions theory have also led to development of some other theories (Axtell pg 87-88). Doubt has also contributed to increased knowledge in other areas, for example, in social science and history. There are two areas that information collected or knowledge gained depends on research or theories which were constructed in the past by various scholars. However it becomes tricky to use such kind of theories to their full because history and social sciences are dynamic. For example, the society change as time moves. Therefore, this is also in the same way that the theories are supposed to change. For example, if theories that were constructed in the fourteenth century are used in the twenty first century then there is no doubt that the theory would contain a lot of faults because of the changes that have occurred in the society. People have developed in their way of reasoning as in these days there are more sources of information than in the past. Reason is one part of gaining knowledge that enhances the development of doubt. This is because it is after deductive reasoning that a person is able to develop hypothesis that proves some knowledge as relevant or irrelevant (Gotschl, pg179-180). Historians do their research and base most of their research on the researches that were conducted in the past. The information in the research where they base their research would be biased or exaggerated. This is what cause doubt and enhance new research to be conducted regarding some issues. Despite the fact that some people are emotionally attached to some believes doubt has made them to relent some of their believes. For example, different ethnic groups have their own myths about where they originated or who is their god or where their god lived. In traditional society people had strong emotional attachment to these beliefs (Chang pg 581). However, as time has passed people have developed doubt about these believes to develop other believes. This is because most of the beliefs in the traditions are not well reasoned and are also biased to particular ethnic people. People have developed other believes that are more inclusive of other ethnic groups all over the world. This has risen out of the doubt that people have some of the things that happened in the past (Lamm Norman pg 11-12). Despite that knowledge plays a key role in knowledge I think that knowledge or truth is a fixed situation because truth is not questionable. So if true knowledge is out there to be discovered or to be learned then it means that when we know or acquire knowledge then there should be no room for doubt. I also think that knowledge depends mostly on human perception. Natural sciences have more upper hands in investigating the truth. However these sciences are still subjected tout human brains. Curiosity is also key to knowledge rather than doubt. Human beings are always curious to know more about their nature. The curiosity allows them to make discoveries and also strive to find the truth. Looking critically at the discoveries that have been made in the past it is out of curiosity that this has happened. This curiosity leads to knowledge, which then leads to wisdom. Doubts make us to know hat our knowledge is correct instead on believing in something blindly. However I do not feel that doubt makes us to make any discovery or learn anything that is new to us. It is curiosity that allows us to acquire new knowledge more quickly. Work cited Axtell Guy.
