Absolute Appraisal Method Essay

The Absolute Standards Approach is an appraisal method used to assess the performance of employees by presenting a detailed description of the employees’ actual behavior in comparison to a certain set of standards. In this type of appraisal format, the appraisers compare the employees to a certain set of standards, which may come in the form of checklists, rating scales, etc, rather than to other employees within the organization. The Absolute Standard Appraisal method has 4 techniques: Checklists, Essays, Critical Incidents, and Behaviorally Anchored Rating Scales. Checklist is the most common technique used by companies. It is a rating containing statements describing both effective and ineffective job behaviors. Behavioral checklists are well suited to employee development because they focus on behaviors and results, and use absolute instead of comparative standards. An advantage of using checklists is that evaluators are asked to describe rather than evaluate a subordinate’s behavior. The supervisor weighs the high and low points on his list and comes up with an overall rating for employee performance. On the other hand, a disadvantage of using checklists is the money and time it can consume for the construction of its instruments. The essay method is a written narrative assessment for employee performance. The employers indicate the subordinate’s strengths, weaknesses, potentials and areas of improvement in the workplace. A disadvantage of essay appraisals is that they can be very time-consuming, and to a large extent, unstructured. It may also come as discriminatory and susceptible to evaluator bias, which may misrepresent the real picture of the employee or the performance. Critical Incidents are specific behaviors essential to doing a job successfully. Behavioral traits that employees exhibit in the workplace – both effective and ineffective, are documented in writing. Employers then analyze these incidents from which a checklist is developed, indicating employee’s critical incidents that either needs praise for successful performance or training for further improvement. Behaviorally anchored rating scales (BARS) are rating scales, which define scale points with specific behavior statements that describes the varying degrees of performance. The scales represent a set of descriptive statements, ranging from the least to the most effective. It combines the elements from critical incident and graphic rating scale approaches. The evaluator must then indicate which behavior on each scale best describes the employee’s performance.

Indian Institutes of Management and Interview Essay

With academic internships on Internshala (likes of CERN, JNCASR, EPFL etc.) ruling the roost, we have been inundated with requests for tips on how to write an impressive Statement of Purpose (SOP). The kind which grabs selection committee’s attention and forces them to accept you in one go. We present, a been there and done that, expert telling you the finer nuances of how to write an effective SOP. About the author: – Nirmal Jayaram graduated from IIT Madras in 2006 post which he did his M.S & Ph.D from Stanford University. Whether Nirmal is synonymous with the term Academic Brilliance or coined it; I am not sure. Sample this – he graduated with a CGPA of 9.54 from IIT Madras (last 4 sem GPA being 10/10), he had calls from all 6 IIMs and attended interviews of only 2 and converted both including IIM Ahmedabad. But of course he did not join it. He had admits with full scholarships from Stanford, MIT, Berkley, Cornell, UTA, & Purdue. Rumors has it that MIT admissi on committee stalked him for weeks to swing his decision in their favor and sulked for months when he went to Stanford instead. With these credentials, if I were you I would pay VERY close attention to what he has to say on SOP writing. Happy reading†¦ 1. Understand what a statement of purpose means: You’ve probably been in situations where you have to choose one among several exciting alternatives. Recruiters face the same scenario while dealing with several good resumes intended at the same job opening. The statement of purpose gives you an opportunity to connect all your application materials together and express to the recruiter why you fit the role the best. To understand what goes into a good statement of purpose, you need to put yourselves in the recruiter’s shoes, and try to get a feel for the two burning questions a recruiter has: 1.Why are you interested in the opening? Sometimes the answer to this might be obvious. You current area of study/ work could well be closely related to the job opening, but it still can’t hurt to clearly enunciate your interest in this area of work and how that helps you move further in your intended career path. Naturally this is much more important whe n the job opening is in an area unrelated to your current area of work, although you might believe that the new area is really your calling. The end goal is that the recruiter needs to believe that you are very serious about this opening and you would give it your all once you actually get the job. More on this later. 2.What do you bring to the table? So, you have shown the recruiter that no one could be any more serious about the opening than you are. You’ve won half the battle, but you still need to prove that you are not all bluster and you are capable of performing the work at a very high level. Your resume does this for you partly, but the statement of purpose gives you an opportunity to highlight some of your major achievements and skill sets that are closely related to the job of interest. 2. Tell a story, your story! Let’s talk about structuring your statement of purpose for a bit. Your statement of purpose needs to tell your story in such a way that the recruiter clearly understands your background, your capabilities and your suitableness for the job. There are many ways to structure a statement of purpose, and this would be one: †¢Who are you and what do you do currently? Start out with your current education background and what got you there. Maybe you were inspired by pure science as a kid and ended up as a physicist. Maybe you were excited by the world of algorithms in high school that inspired you to pursue the field of computer science. Or maybe you even wanted to build the next Eiffel tower and decided to become a Civil Engineer! †¢What are your current academic credentials? Dedicate some part of your statement of purpose to explain your academic achievements and credentials in your current education program. If you did great in your college entrance exam or in your college exams, state it here and explain how this reflects your dedication to your current field and the hard work you are ready to put in. If you won scholarships through, for example, the National Talent Search Examination, make sure the recruiter kn ows that. †¢What is your current state of knowledge? Most disciplines are very broad and diverse, and it is imperative that you explain your specialization in more detail. Discuss your coursework and explain why you chose to specialize in the area that you did. Suppose that the job opening requires an intern that pursues research in the analyses of large data sets. You could be a mathematician and might have pursued a diverse set of courses, but you need to explain why the field of data mining excites you the most. You need to specifically identify your data mining-related coursework that clearly illustrates that you have the theoretical background to succeed at this new job. †¢Discuss your past projects: This is particularly critical for research based jobs that require that you be creative, comfortable working in open-ended problems, good at communicating orally and in written, and will not get easily frustrated by occasional difficulties in furthering the project due to research complexities. Some jobs also require that you be capable of working without much guidance or work as part of a large team. The most obvious way to communicate that you possess the above-mentioned skills is to provide a brief description of all your past proj ects and the skill sets you demonstrated along the way. Any journal or conference papers that you published as part of your projects will go a long way in helping you get a research-oriented job! †¢Discuss your non-technical skills: A lot of successful people are technically sound but also charismatic and possess excellent interpersonal skills. These are almost essential qualities in modern work places and activities that you’ve been part of where you have demonstrated these skills should help you big. Such activities include playing a leadership role in a department or college level association, being part of NSS, or maybe even running your own small startup! †¢Identify yourself with the company/ university: It is of utmost importance that your statement of purpose does not look generic, rather seems well crafted to the specific job opening. It would be wise to discuss briefly about your interest in the specific workplace and not just the nature of work, and in particular detail the attempts you’ve made to learn m ore about the workplace. 3. Ensure that the statement of purpose is written in a professional manner: A poorly worded statement of purpose with spelling or grammatical errors is a big turn off that would certainly hurt your cause. Request help from friends and colleagues regarding possible wording changes that would make the essay look more professional. Avoid terminology and wording that aren’t obvious to the reader, and remember that different countries may use different terminologies to refer to the same word. Keeping these sensitivities in mind will help. 4. Be brief: Recruiters do not have the time or energy to read through a rambling 4 page essay. The statement of purpose shouldn’t exceed a couple of pages and should be to the point. We are not trying to author the next Lord of the Rings here! Statement of Purpose (SOP) is a document containing one’s personal and professional details which makes the task of knowing a candidate for the MBA school much easier. It is a concise essay about one’s career goals, identified means to achieve them, and accomplishments so far in reaching towards those goals. An SOP often acts as the yardstick for assessing the capabilities of a prospective student of the MBA School. What should your SOP contain? According to top experts the answers to the following queries must be there in your SOP: — You, your background and personality — The reason or reasons for making a particular career choice — Your hobbies — Your short-term and long-term career goals — Social initiatives taken by you, if any — Leadership qualities demonstrated by you — How you have dealt with failure — Example of teamwork at the workplace — Strengths and weaknesses — Ethical dilemmas faced by you Preparing for writing the SOP Some suggestions on how to prepare for writing the SOP: — Think deeply about matters concerning you, your choices and aspects of personality. — Adopt pre-writing strategies and jot down thoughts as they occur — Prepare a rough draft and proofread it to remove any errors. — Start well in advance. While writing the SOP SOP is an extremely important document that you will have to prepare before you will be accepted into any MBA School. You must ensure that your SOP lacks any kind of spelling or grammatical error. Your ability to write at an acceptable level will tell a great deal about you as an overall student, so do not neglect to proofread your document before submitting it. The SOP must make an interesting read; otherwise it won’t leave any impact on the readers’ minds. Integrate your knowledge about the B-school with your career goals, as this will make it seem as though there is really no other school that you are thinking of attending. Some important points to keep in mind while writing the SOP: Originality The answers have to reflect the distinctive ‘you’ all the way. So, be original. Copy –Paste exercises will do more harm than good as one shoe size does not fit all, especially in terms of personality. Relevance Read the question very carefully before you start framing your essay. Consider the question: â€Å"Please detail your long-term career goals. Why have you classified them as long term? Do you foresee any change in these goals in the future?† Now, you must be careful in crafting a reply to each question in a convincing manner. Concentrating only on the first segment will make the statement lopsided and put off the admissions panel. Conciseness Every word, every sentence should be present in the essay for a purpose. Rambling and undirected thoughts are a no-no as your essay will be given a couple of minutes within which the panel member has to locate something memorable and distinctive. Imagery Imagery means using words that enable pictures to form in the minds of the reader. For example, the phrase ‘turning point’ is better than writing ‘The course of my life changed decisively at that point because it succeeds in giving rise to a picture in the mind of the reader. Avoiding jargon Using too much jargon clichà ©s or long-winded sentences obscure the point you want to convey. Professional tone and elements of standard usage There is a world of difference in the way we speak and the way we write. You should avoid informal style or slang while penning the academic essay. Keeping the standard elements of usage in mind will go a long way in ensuring admittance in the MBA School. It takes a lot of time and engages your mind to undergo lot of thinking before you come up with the perfect SOP. So you should start much before. All this takes time, so begin writing the SOP well in advance. Stay tuned to MBAUniverse.com for more on MBA admission tips! CAT Toppers share their GD, PI & WAT experiences When a student is selected by a top B School, it is ensured that he has not just scored well in CAT but has also performed well in the Group Discussion, Personal Interview and or Written Ability Test (WAT) or Essay Writing rounds. This page will give you the GD, PI & WAT experiences of the CAT 2011 toppers who are now students of the academic year 2013-15 of the top B schools. I had an enjoyable WAT & PI experience of IIM Ahmedabad B Sekhar Anand IIM Ahmedabad Tricky WAT by IIM Indore Vishal Vyas IIM Indore My interview at XLRI lasted for 15 minutes Arjun Gupta XLRI Jamshedpur I had a grilling interview session at Common Admission Process of new IIMs Siddhant Gupta IIM Raipur WAT & PI experiences of top 3 IIMs Anusha Subramanian IIM Bangalore If you are a fresher, be thorough with your subjects for PI Parag Poddar IIM Indore My WAT topic was on foreign coaches at Indian sports Aditya Agar IIM Bangalore My interview experience was different in the top four IIMs Mohit Srivastava IIM Bangalore There was no stress at my interview; it was a candid conversation with learned men Tanishq Goyal IIM Ahmedabad I had an enjoyable WAT & PI experience of IIM Ahmedabad, B Sekhar Anand IIM Ahmedabad Q: Please share your WAT/PI experience in detail. A: My WAT/PI experience was very enjoyable. The topic for WAT was on corruption’s affects- a topic that I was comfortable with. The PI on the other hand was skewed towards my academics. A lot of preparation beforehand helped me answer most of the questions. Though I could not answer a few, the interviewer was fairly satisfied with my approach to those questions. Tricky WAT by IIM Indore, Vishal Vyas IIM Indore Q: Please share your WAT/PI experience in detail. A: WAT and PI were the two vital stages of IIM Indore selection process. WAT was somewhat tricky with a question on prà ©cis writing and another asking about my opinion in a given situation where a choice was to be made between a family managed business and a professionally run organization. PI probably was the most challenging part, with the interviewers asked extensively about by job profile and nature of work apart from a good amount of general knowledge. Work experience was somehow a difficult part to tackle with questions ranging from basic programming concepts to industry quality standards and their constituents. Overall, it was a mixed kind of interview which had its own high points and lows. I was hoping to convert with a good performance on almost all the measures which I later did. My interview at XLRI lasted for 15 minutes, Arjun Gupta XLRI Jamshedpur Q: How many GDPI rounds have you had? Please share your experiences in detail. A: I attended the GDPI rounds for the following institutes: †¢ NMIMS, Core †¢ XIMB, PGDM & PGDM(HRM) †¢ SPJIMR(FIN) †¢ XLRI (BM & HRM) SPJIMR’s admission process is unique in the sense that they call you on the basis of your profiles. In the group interview rounds also, the emphasis is on ethics and values. They question you comprehensively on your work-experience, if any. XLRI has a single PI round for the BM program. The interview covers all the important points, viz., work-experience, Graduation subjects (Math, especially for Engineers), current affairs and ethics. Highly unpredictable stuff, I must say. The HRM program has both GD & PI components. My interview went on for around 15 minutes in which I was questioned a lot about cultures, economies and technologies. I was asked to relate the factors citing suitable instances. Some questions on work experience and mathematics were also there. GD topic was related to IT sector. It was pretty basic hence I did not face any problem during the GD. XIMB had a single GDPI round for its BM and HRM programmes. The GD was related to Income disparity and was manageable. The interview again revolved around my work-experience. We had a very candid discussion instead of an interview. I could easily answer all their queries related to work. NMIMS’s GD was related to the airline sector. The interview was about Petrol/Diesel pricing, Basic Share Markets term and history about my parent company. For all the above GDPIs, I brushed up my Graduation Subjects well. Read about the major issues which are plaguing the nations, basic indices to measure economic health & society, knowledge about the parent company, its product profile, job role, etc. I had a grilling interview session at Common Admission Process of new IIMs Siddhant Gupta IIM Raipur Q: Please share your WAT/PI experience in detail A: I had my WAT/PI in Delhi. I was given a topic on financial crisis in Europe. I was asked to speak on any topic from current affairs during the interview. I chose to talk on KFA bailout. I explained the problem and was asked for possible solutions. I suggested some solutions and a few cross questions were fired. Then I was asked a few questions on chemistry (I am a chemical engineer). Towards the end, I was grilled on â€Å"Which IIM will I choose if I happen to get multiple converts†. I linked it to the question related to the meaning of name and the panel seemed impressed. WAT & PI experiences of top 3 IIMs, Anusha Subramanian IIM Bangalore Q: Please share your WAT/PI experience in detail. A: Let me share my experiences of attending IIM Calcutta, IIM Ahmedabad and IIM Bangalore. IIM Calcutta – I had a good WAT and GD. My interview was mostly about events doing the rounds, a few maths questions, logic puzzles and some general questions about my future plans, etc. IIM Ahmedabad – The WAT was tricky as we were given only 10 minutes to complete the essay. I was questioned on a wide range of topics ranging from work, recent happenings in the software industry and academics. IIM Bangalore – My interview with IIM Bangalore was almost entirely based on the statement of purpose submitted earlier. I was quizzed in great detail about specific points in my SOP, regarding my work experience and future plans. If you are a fresher, be thorough with your subjects for PI, Parag Poddar IIM Indore Q: Please share your WAT/PI experience in detail. A: The WAT process for IIM Indore involved summarizing an article in one-third word limit and was followed by essay writing. I had been practicing essays during my GD/WAT preparations and this helped me perform well in the WAT section. This was followed by PI. Being a fresher, I was questioned thoroughly on my subjects. Professors checked every aspect of my personality through questions on general awareness, GK, current affairs and my background. The interview was a great learning experience and helped me gauge myself better and identify areas of improvement. My WAT topic was on foreign coaches at Indian sports, Aditya Agar IIM Bangalore Q: Please share your WAT/PI experience in detail. A: At IIM Bangalore’s WAT/PI process, I was asked to first write an essay on ‘Foreign coaches are a waste of money in Indian sports.’ My interview was centered on my experience at work and I was asked a lot of questions on the contributions I made to the organization. All in all, the interview was a big test of finding out what I gave to the organization I worked for and to the college I came from, which, trust me is very difficult to comprehend. My interview experience was different in the top four IIMs, Mohit Srivastava IIM Bangalore Q: How was your WAT/PI experience? A: The interview experience was very different at all the four IIMs. IIM Lucknow was focussed more on general affairs. IIM Bangalore was mostly academics and SOP based (they actually asked me an algorithm) IIM Calcutta was purely quant based in terms that the first five questions were based on Permutations and Combinations. After I satisfactorily answered them the interviews started asking me questions on Seattle and where all I had been in Seattle. IIM Ahmedabad was very unpredictable in terms that most of the questions were not from my strength. It was somewhat less academic. There was no stress at my interview; it was a candid conversation with learned men, Tanishq Goyal IIM Ahmedabad Q: Please share your WAT/PI experience in detail. A: I got calls from all 13 IIMs, but I gave interviews for the top four only. In IIM Ahmedabad, the WAT topic was In today’s world, business and ethics don’t go hand in hand. The questions ranged from my work experience, solving math problem, my hobby tennis to politics. The entire interview was like a candid conversation with learned men on some random topics. There was no stress at all. Personal Interview A personal interview is aimed at knowing a candidate more intimately – assessing the clarity of thinking process, future goals and the ‘fit’ with the B-school. A personal interview is aimed at knowing a candidate more intimately – assessing the clarity of thinking process, future goals and the ‘fit’ with the B-school. Personal Interview – What does it test? Analytical Skills †¢ During the personal interview, Interviewer will check the analytical skills of the candidate in ways that cannot be done with a written test. Certain questions during the personal interview are devised to see how the candidate can analyze a situation and create a solution. For example, an employer may ask a candidate to explain a time when the candidate had to work quickly against a pending deadline. In the personal interview, the employer can ask follow-up questions to dig deeper into the candidate’s critical thinking process, to see if he/she fits to be a part of the Institute/organization Goal Clarity †¢ Why do want to do an MBA? How does it fit into your career goals? What do you wish to do after your MBA? These are some hard questions that you will have to answer almost invariably in all Interviews. These questions search the ‘inner motivations’ of a candidate, and there are no ‘right answers’. The only way to answer these questions is to introspect: what excites and motivates you; what makes you perform your best; what would you really like to do in your life, and how do you genuinely see an MBA helping. Tough questions, but answering them honestly is critical for your success! ‘Why MBA?’ is the most important question that MBA aspirants need to answer. There is no â€Å"good answer† for this. The answer needs to be your answer. In other words, you need to think deeply, introspect and find out what it is that really drives you. So put on your thinking cap, do some soul searching and then jot down the answers to ‘what†™s your goal’ questions. Communication †¢ When an employer is engaged in a personal interview with a candidate, he will listen to hear how the candidate gives answers to questions, watch for body language that can indicate the candidate is not being truthful or is uncomfortable; determine confidence by gauging eye contact. Is the student is able to effectively communicate using his entire body, etc and these skills can only be judged during a personal interview. Domain Knowledge †¢ Given that a good MBA is a demanding programme, B-schools would like to know how you will be able to cope up with the academics and the extra-curricular 24 x 7 demands of your new campus. They are also keen to assess how you have utilized the earlier learning opportunities. Be prepared to discuss different specialty areas in business and their responsibilities. Interviewers will also expect you to discuss current issues in business, including the economy, taxation, foreign competition, the role of technology and ethical challenges in the field. So be careful about the gates you open, and be very sure you have in-depth knowledge about whatever you mention. For e.g. if you say you have an avid interest in Badminton, be ready for questions pertaining to Prakash Padukone, Deepika Padukone, plastic shuttles v/s feather shuttles, Saina Nehwal etc. It is advisable to brush up 2-3 subjects from your graduation thoroughly if you are a student fresh out of college. Also, contextual knowledge of the environment around you as well as â€Å"general knowledge† comes quite handy. Presentation †¢ Candidates who do not take the time to create a professional presentation for a personal interview can hurt their chances for getting the job. A personal interview gives the employer the opportunity to see what the candidate considers to be professional grooming, professional attire and a professional attitude. A candidate’s resume may be impressive, but if he shows up to the interview 30 minutes late and is not dressed in professional interview attire, then he may not be the candidate you are looking for. Attitude †¢ In a personal interview it is not always the answer you give to a question that is important, but how you give that answer. An interviewer is well aware of the corporate culture within his institute and a personal interview gives the interviewer a chance to gauge the candidate’s attitude to see if there is a match with the institute. Importance of an Interview: Who Conducts MBA Interviews? Every business school has different policies when it comes to MBA interviews. Typically, an MBA interview is conducted by one or more members of the admissions committee. However, it is not unusual to be interviewed by current students or alumni. Professors do not normally conduct admissions interviews, but there are a few schools who do assign faculty members to the task. No matter who interviews you, expect a lot of questions and an evaluation. Most admissions committees have a form that they work off. They will ask you specific questions from the form. If you are being interviewed by other students or alumni, don’t expect anything different. They have probably been trained by the admissions committee to use the form or ask specific questions. Read more about the different types of MBA interviews. Personal Interview can also turn out to be an opportunity to ‘sell’ yourself. While intimidating for some MBA-hopefuls, the personal interview represents a prime opportunity. Interviews allow you the chance to not only put a face and personality to the name and credentials on your application file, but also to express your academic, personal, and professional accomplishments, experiences, and intentions.

Acid Rain Essay Example for Free (#3)

Acid Rain Essay Essay Topic: Acid rain , SO2 Choose cite format: APA MLA Harvard Chicago ASA IEEE AMA company About StudyMoose Contact Careers Help Center Donate a Paper Legal Terms & Conditions Privacy Policy Complaints ? Acid Rain is rain, snow or fog that is polluted by acid in the atmosphere and damages the environment. When fossil fuels are burned they release mostly CO2, but they also release two harmful gases, sulphur dioxide and various nitrogen oxides. The sulphur dioxide, SO2, comes from the sulphur impurities in the fossil fuels. However, the nitrogen oxides are created from a reaction between the nitrogen and the oxygen in the air, caused by the heat of the burning. When these gases mix with clouds they form dilute sulphuric acid and dilute nitric acid. Cars and power stations are the main causes of Acid Rain. Acid Rain has effects on plants, soil and even buildings. The acid reacts with the limestone and then the limestone begins to erode. From previous knowledge, I know that limestone has the chemical formula CaCO3. Limestone, chalk and marble are all calcium carbonate. When an acid reacts with a metal carbonate (such as calcium carbonate) the fizzing shows that a gas is produced. That gas is carbon dioxide, CO2. Adding hydrochloric acid to a rock sample is one of the tests for a carbonate rock, like marble, chalk or limestone. It is also why these rocks are greatly affected by acid rain. The word equation is for this reaction between calcium carbonate and hydrochloric acid is: Calcium carbonate + hydrochloric acid –> calcium chloride + carbon dioxide + water The chemical formulae for this reaction between calcium carbonate and hydrochloric acid is: CaCO? + 2HCL –> CaCL2 + CO2 + H2O The rate of reaction can be calculated by measuring amount of Carbon dioxide gas that is obtained by the syringe. There were various types of apparatus which I included: Goggles Syringe Stop clock Measuring cylinder Spatula Hydrochloric Acid Marble-Powder and Chip Boiling tube Bung Preliminary experiment. Before actually beginning my investigation, I will firstly carry out a preliminary investigation. This will help me to see the improvements that I can make after the experiment. I will be able to see possible downfalls and failures in my method, work out appropriate quantities of chemicals to use and generally improve the quality of the final experiment. Below is the set up apparatus that I will use for the preliminary experiment and the actual experiment: The preliminary experiment is performed so that I can predict the volume of acid, the mass of the chip and powder and the length of time that I will be timing for. 1. Firstly, I set up the apparatus. 2. I will specify a curtain mass of marble using a balance and I will place it into the boiling tube. 3. Then, I will measure a quantity of acid and quickly add it to the boiling tube whilst after quickly placing the bung onto the top of the tube. 4. I will record the amount of CO2 gas which is given off, every curtain amount of time. This will produce a rate of reaction. For many experiments the rate of reaction can be changed by altering curtain variables. For this reaction there is no catalyst, therefore we cannot alter this variable. However there are three main variables that could be changed: Temperature of the acid – this would be varied by starting off with the acid at room temperature (around 24i C) and then using acid with temperatures of 30i C, 40i C and 50i C. Concentration of the acid – the concentration would be varied three times, using hydrochloric acid with concentrations of 0. 5M, 1M and 2M. Surface area of the calcium carbonate – the surface area would be varied by using different sizes of calcium carbonate. I will predict that the 2m acid and the powder will be the fastest reaction as the acid is more compact with acid particles in the same volume of water. This helps more successful collisions take place between the particles. The more collisions there are the increased rate of reaction. I found out that I should use 1 gram of mass for the chip and powder marble and 30cmi of acid. This is because the reaction is not too fast or slow. I can get an acceptable number of results recorded. I will be using three different concentrations of acid, 0. 5m, 1m and 2m. (m=molar) The time I will be using will be starting at when the syringe starts to move up to 180 seconds. I will be keeping the amount of acid the same and the mass of the marble so that I conduct a fair test. The temperature was kept at 24i C-25i C. Results 0. 5m with chip 0. 5m with powder Mass of chip = 1. 0g Mass of powder = 1. 0g Time (s) Volume (cmi ) 10 2 20 4 30 5 40 6 50 7 60 8 70 9 80 16 90 17 100 18 110 20 120 21 130 22 140 24 150 25 160 26 170 27 180 31 Volume of acid = 30cmi Volume of acid = 30cmi Time (s) Volume (cmi ) 10 14 20 17 30 19 40 20 50 22 60 23 70 23 80 25 90 29 100 34 110 35 120 37 130 38 140 38 150 38 160 39 170 40 180 40 1 m with chip 1 m with powder Mass of chip = 1. 0g Mass of powder = 1. 0g Volume of acid = 30cmi Volume of acid = 30cmi Time (s) Volume (cmi ) 10 21 20 30 30 36 40 38 50 39 60 31 70 42 80 43 90 43 10 44 110 44 120 44 130 44 140 44 150 44 160 44 170 44 180 44 Time (s) Volume (cmi ) 10 4 20 5 30 6 40 9 50 12 60 15 70 18 80 21 90 24 10 27 110 31 120 34 130 37 140 40 150 44 160 47 170 50 180 52. 2 m with chip 2 m with powder Mass of chip = 1. 0g Mass of powder = 1. 0g Volume of acid = 30cmi Volume of acid = 30cmi Time (s) Volume (cmi ) 10 5 20 9 30 13 40 16 50 22 60 26 70 33 80 36 90 46 10 46 110 46 120 51 130 54 140 57 150 57 160 57 170 57 180 57 Time (s) Volume (cmi ) 10 0-60 20 † 30 † 40 † 50 † 60 † 70 † 80 † 90 † 10 † 110 † 120 † 130 † 140 † 150 † 160 † 170 † 180 † Conclusion. After completing my experiment my results show me that as the concentration of the acid is increased, the reaction takes place faster and more gas is produced in a shorter space of time. Due to this I found that the 2M hydrochloric acid (the strongest concentration of acid I used) produced the most gas in the shortest time. The 0. 5M hydrochloric acid (the weakest concentration of acid I used) produced the least amount of gas in the longest time period. I can clearly see from the graph that the 2M hydrochloric acid gave the fastest reaction and produced the most gas in the shortest space of time, because the gradient of the curve is the steepest and goes far higher than the other curves showing that a larger amount of gas was produced because the ‘gas produced’ axis is the ‘y’ axis. The fact that the 2M acid had the steepest curve shows that the reaction was fastest because a large amount of gas was produced (high on the y axis) and in a short space of time (short on the x axis). This will give a steep gradient on the graph. The 0. 5M hydrochloric acid gave almost the opposite curve when the results were placed on a graph. Not much gas was produced in a long space of time and so the slope was very gentle and low on the graph. The 2M hydrochloric acid produced the most gas in the shortest amount of time and was generally a quicker reaction due to its significant difference in particle arrangement compared to the 0.5M and 1M hydrochloric acid. The more concentrated 2M hydrochloric acid has more acid particles in the same volume compared to the 1M and 0. 5M acid. This means there are more available acid particles to react with the calcium carbonate. The reaction will be quicker when using the 2M acid because there are more particles available to react with. The calcium carbonate particles can react with more acid particles quickly as they are easily accessible, whereas in the 0. 5M acid, there are few acid particles in a volume and so some calcium carbonate particles will have no acid particles to react with, causing the reaction to be slow and uneventful. All reactions will only occur if there is enough energy to make it happen. This minimum energy is known as activation energy. Activation energy is the minimum energy for which two reacting particles must collide for a reaction to take place. When particles collide they slow down, stop, and then fly apart again. This will occur regardless of whether they have enough energy to react. In an unsuccessful collision the particles separate unchanged, but in an effective collision the activation energy barrier is crossed and the particles that separate are chemically different from those that came together. I think my results are definitely sufficient to support my prediction. They equal everything I predicted and I am very pleased at how well they turned out. Evaluation I think that the experiment went very well. All my results matched my prediction and everything went ‘according to plan’. The gas produced by each acid had a steady increase however; there were a few rogue points. Overall I achieved what I set out to do. I would have liked more time on the experiment to make sure everything was perfect, though. Due to the short time limit we were quite rushed in completing the experiment. There were a few aspects of the experiment that could have been improved to make the experiment even more accurate. For a start the experiment was undertaken over a few days. Each day had a different temperature and so this would have affected the results. If one day had been hotter than the others the heat would have influenced one reaction to take place faster. Also due to the fact that the experiment lasted a few days, different equipment was being used each day. Some gas syringes were slightly stiffer than others and so wouldn’t move out as fast. If on one day you had a very stiff gas syringe that wouldn’t move very easily and on another day you had a very loose gas syringe, then the results would be very different as the loose gas syringe would give results that say that the reaction happened very fast and the stiff gas syringe would give results that say the reaction was slow. To prevent this from happening the experiment should have been undertaken and finished on the same day, using exactly the same equipment as you started with for each acid. The initial part of the reaction when the acid first reacts with the calcium carbonate is very fast. A lot of gas is produced at the beginning of the reaction. However the way the apparatus are set up means that when you pour the acid onto the calcium carbonate, there are a few seconds when the gas is able to escape before the gas syringe is connected to the test tube. To avoid this from happening a test tube containing the calcium carbonate should be placed inside a beaker containing the hydrochloric acid. They must not be touching, as the reaction would then start. Then the gas syringe will be connected to the beaker. When the reaction is ready to start, the beaker is knocked so that the test tube falls over, consequently causing the reaction to take place as the acid and carbonate would mix. Then when the initial gas is produced it will all be ‘caught’ as the gas syringe is already in place. The surface area of the calcium carbonate should also have been kept equal. The same number of equally weighted chips should have been used. E. g. all 1g chips. This way the reaction is fair and accurate, as a large surface area will cause the reaction to take place faster. Keeping all the surface areas the same would have kept the experiment fair. However to do this would have taken a long time and we only had a limited amount of time. Another way of keeping the temperature the same would have been to do the experiment in a water bath. This would have allowed us to do the experiment over a few days as well. Acid Rain.

Response paper Essay Example | Topics and Well Written Essays - 250 words - 7

Response paper - Essay Example Countries like China and India are in the development phase and are looking to establish themselves more in the international economy. For this purpose, they require more and more energy and as this energy is produced, more greenhouse gases would be emitted. The US and European countries, on the other hand, can afford to invest in the development of Clean Technology because they are well-developed. International cooperation asks all the countries to take certain measures to reduce the GHG. Such measures are acceptable for developed countries but under-developed countries cannot afford to comply with such requirements because of their energy needs. When these countries do not comply with international treaties, the other countries also pull out of such treaties. Apart from the economic needs, countries may also opt not to comply with a treaty because they do not want to follow the lead of Western countries. For instance, history tells us that China rarely followed the lead of US on ma ny occasions. The treaties made for better environment can work only when they are harmonized and every country contributes. This has not been the case in the Montreal Protocol and the Copenhagen

Automobile Workers vs Johnson Controls Inc Case Study

Automobile Workers vs Johnson Controls Inc - Case Study Example Eight employees of a battery manufacturing company who were pregnant exhibited increased lead quantities in their blood – more than what OSHA approves to be a considerable amount (Rehnquist, Kennedy, & Scalia, 1991). The company later barred all women from working in lead related departments except those who could not have children, though after passing clinical tests to ascertain their conditions. This prompted a group of employees to file a case in the District Court. They argued that the policy discriminated against the female gender and violated Title VII of the Civil Rights Act of 1964 (Rehnquist et al., 1991). The District Court and the Court of Appeal granted the respondents a summary judgment on grounds that their fetal protection policy is reasonably necessary to further the industrial safety concern. The petitioners claimed that excluding fertile women from lead-exposed jobs, the respondent's policy creates a facial grouping based on gender besides marginalizing them under 703(a) of Title VII (Rehnquist et al., 1991). They claimed the policy is not neutral because it does not apply to males despite evidence that lead exposure poses great harm to their reproductive system. They cited that provided that the fertile women performed their duties as expected, the company has no right to segregate them. However, the respondents argue that they are concerned about the other coming generation’s status regardless of the law exclusively being for the parents (Rehnquist et al., 1991). Ethical Issues Is the company in line with professional work ethics and fair gender opportunities law by passing the policy discriminating fertile and infertile women from working in the lead related departments? No, the company does not satisfy its expected moral and ethical standards as required in the society by passing a policy that stigmatizes the female gender. Additionally, it also violates Title VII of the Civil Rights Act of 1964 that protects all genders fro m discrimination. By so doing, the company would be creating a facial categorization that utilizes gender to segregate women (Rehnquist et al., 1991). The policy is not neutral and fair to both genders and how lead affects them either. According to the company, lead affects only the female gender despite concrete evidence that it poses adverse effects on the male reproductive organs. The law also cites that unless the pregnant employees differ from others in their expertise, they must all get both equal treatment and opportunities (Rehnquist et al., 1991). In addition, legislative history and case law bar an employer from discriminating against pregnant women or their pregnancy capacity unless their condition prevents them from performing the expected duties. The employees’ fetuses are neither customers nor employees whose safety is a concern of the company’s management (Rehnquist et al., 1991). In this context, the respondents should get rid of their policy as the fem ale fertile employees participate in manufacturing lead batteries similar to other peers. Alternatives Would getting rid of the policy of the company not tarnish the company’s image and still keep the fertile female employees’ comfortable working for the company? Yes, this move by the company would motivate fertile females in the company besides prompting them to work more comfortably and harder than before. This would also be a means of enhancing good publicity of the company in the society because the policy adheres to the female discriminatory law, which contradicts with business ethics (Rehnquist et al., 1991). However, by taking this move, the company would be putting the fetus, the fertile mothers and their future families at great risks. This is because lead exposure to fertile women

What will happen to Iraq if the US leaves Essay

What will happen to Iraq if the US leaves - Essay Example One of the most important events in the current world affairs is the invasion of Iraq by the US and there have been several essential voices arguing that it is high time for the US to leave the region to set the Iraqis free to pursue their political and economic destiny. Critics who regard the invasion of Iraq by the US as a serious offence against the freedom of that nation argue that America needs to establish normalcy in the region before they leave the land. "No one can say with confidence what will happen in Iraq if the United States leaves precipitously and without making a continuing effort to compensate for its mistakes and failures. It is easy to talk about intensive civil war, 'blood baths', and an international resurgence of al-Qaida. Such worst cases are possible, but the most likely result is less violent sectarian and ethnic cleansing, and the de facto division of much of the country." (Cordesman and Davies, 2008, p 737). Therefore, the most essential question in the pr esent context is not whether the US invasion of Iraq is justifiable or not, but what happens if the US leaves Iraq all on a sudden. In this paper a careful and reflective analysis of this essential question concerning Iraq's future if the US leaves the region is conducted and the discussion in this regard not only is vital to an understanding of the political system in the US but also to an understanding of some of the most important world affairs as well as affairs in the Iraqi region. In a careful analysis of the current situation in Iraq, it is essential to comprehend that there are several benefits if the US army stay longer in the region. People, who consider that going into Iraq was a big mistake committed by the US, are greatly concerned about what will happen when USA leaves Iraq. To most of them, it will be foolish to consider that the Iraqis are able to defend themselves against all the issues in the country and the region. First of all, there will be great chaos in the nation and the region if the US leaves immediately. Although there are people who argue for the rapid withdrawal of the US troops from the region, on the basis of the unfortunate developments precipitated by the US invasion of Iraq, it is not logical for the army to leave the region before the Iraqi security forces are self-sufficient. Such a rapid withdrawal of the US troops will inflict long term damage on US credibility and ability to deter enemies and would facilitate the objectives of the al-Qaeda. "In Iraq, the United States has demonstrated that it will stand and fight in the face of adversity when it believes that its core interests are at stake. US determination in Iraq has done much to counter previous jihadists' perceptions of the United States as a 'paper tiger' If the United States leaves prematurely, these gains will be lost and Iraq will join Vietnam, Beirut, Aden, and Somalia in the jihadi mantra regarding US weakness." (Forest, 2007, p 47). Apart from these, it is also argued that some of the powerful leaders from within Iraq can emerge in the nation, take over the government and eventually result in another dictatorship. Also there is a possibility that Iran will invade Iraq and take over it if the US leaves the region all on a sudden. There is a serious argument that "Iraq will become a terrorist haven if the United States leaves." (Preble and Logan, 2005). Reports from the Baghdad confirms that the US withdrawal from the region can affect the norma lization process of the country and "Iraq's foreign minister warned that a quick American military withdrawal from the country could lead to a full-scale civil war, the collapse of the government and
