College and High School Essay Example
College and High School Essay Example College and High School Essay College and High School Essay Essay Topic: High School College and High School BY rnvl 129 College and High School Essay As many of you may know education is very important in our lives because without it you will struggle in life. High school and college have many similarities. Despite, having those similarities, both of them have many differences as well. The similarities and differences that high school and college have are costs, workload, and social aspects. Overall, college is more expensive, has more academic challenges, and offers a better social environment for students than in high school. College is more expensive than high school because of tuition, living expenses, and books. You may choose to live at home when you are in college and most definitely live at home when you are in high school. Many times a student in college may decide to live in a dorm or an apartment, but in high school you are not given that option. Living expenses are around$400-$600 per month. Unlike college, you are provided with all of the books in high school. In contrast, you must pay for the books, which is around $300-500 per erm. In college you must also pay for tuition, which is around $1,500 $2,000 per term when you attend college and in high school you are funded by the government. The workload in college is more challenging than the workload in high school. There are fewer assignments to do in high school. The difference in the number of assignments is very high because for high school it is 1-3 while in college it is 3-5. The final grade for college is 25%-50% and for high school it is 5%-25%. Most of the ssignments in high school are less challenging and time consuming than in college because many of the assignments are easy. In contrast college assignments may take up to 2-8 hours to complete them. College offers more activities, sports, and clubs than high school because students can play on varsity teams while in high school you are not allowed and must find outside programs to be able to Join varsity teams. Most of student in high school are underage and public nights are not allowed. On the other hand, college favors that public night on campus. The activities that are allowed in college but not in high school are Halloween, Valentines Day, and Christmas. It would be great to have a pool in school so you can relax or do other activities in the pool. Well, high school does not have this, but in most colleges it does exist. It is obvious that college is very different in comparison to high school. College is very expensive has more assignments and the environment is around people is outstanding. High school is below college and has fewer advantages when comparing it to college.

Conjugation of Spanish Verbs in the Present Tense
Conjugation of Spanish Verbs in the Present Tense The most common set of verbs in Spanish and perhaps the most important set of verbs that need to be learned first is the presentà indicativeà tense. Although there are conjugations that are easier to learn, the present indicative tense is used the most. Native English speakers conjugate regular verbs all the time without thinking about it: For the past tense add a d or ed to the end of a verb, and for the present tense, add an s or es to indicate that one person or thing is performing an action. Basic Spanish Conjugation Concepts The conjugation of Spanish verbs is a little trickier than in English. A speaker needs to consider several different tenses, moods, gender, and agreement in person according to what needs to be conveyed in the sentence. Spanish verb endings can indicate when the action occurs, and also give the listener a better idea of who or what is performing the action. The present tense means that the action is occurring now. The indicative mood means that the sentence is a statement of fact. Toà conjugateà a verb in the present indicative, remove theà infinitiveà ending of the regular verb, in this caseà -ar,à -erà orà -ir,à and replace it with an ending that gives an indication as to the person that is performing the action of the verb. For example, hablar is the infinitive of a common regular verb ending in -ar.à To form the present indicative, remove theà -ar, which leaves the stem of the verbà habl-. If the person speaking in the sentence is in the singularà first person, that would mean the sentence would be conjugated to be I speak. In Spanish, when conjugating or changing the stem into aà first-person verb, take the stem and add -o, forming the wordà hablo. I speak is Yo hablo. To say you speak, which is the singular, informal, second person, add -as to the stem, forming the wordà hablas. You speak is Tu hablas. Other forms exist for subjects such as he, she, or it, we, and they. The endings are slightly different for verbs that end in -er and -ir, but the principle is the same. Remove the infinitive ending, then add the appropriate ending to the remaining stem. Conjugation of Regular -Ar Verbs in the Present Indicative Tense Person -Ar Ending Example: Hablar Translation: To Speak yo -o hablo I speak t -as hablas you (informal) speak l, ella, usted -a habla he/she speak, you (formal) speak nosotros, nosotras -amos hablamos we speak vosotros, vosotras -is hablis you speak (informal) ellos, ellas, ustedes -an hablan they speak, you (formal) speak Conjugation of Regular -Er Verbs in the Present Indicative Tense Person -Er Ending Example: Aprender Translation: To Learn yo -o aprendo I learn t -es aprendes you (informal) learn l, ella, usted -e aprende he/she learns, you (formal) learn nosotros, nosotras -emos aprendemos we learn vosotros, vosotras -is aprendis you learn (informal) ellos, ellas, ustedes -en aprenden they learn, you (formal) learn Conjugation of Regular -Ir Verbs in the Present Indicative Tense Person -Ir Ending Example: Vivir Translation: To Live yo -o vivo I live t -es vives you (informal) live l, ella, usted -e vive he/she lives, you (formal) live nosotros, nosotras -imos vivimos we live vosotros, vosotras -s vivs you live (informal) ellos, ellas, ustedes -en viven they live, you (formal) live Irregular Verb Conjugation Although most verbs conjugate regularly, the most common verbs in Spanish usually do not. In some cases, not only the endings change, but also the main part of the verb, known as the stem. This is similar to English, where the most common verbs such as to be and to go are also highlyà irregular verbs. Present Indicative Conjugations of Common Irregular Verbs Infinitive Translation Conjugations dar to give yo doy, t das, usted/l/ella da, nosotros/nosotras damos, vosotros/vosotras dais, ustedes/ellos/ellas dan estar to be yo estoy, t ests, usted/l/ella est, nosotros/nosotras estamos, vosotros/vosotras estis, ustedes/ellos/ellas estn hacer to make yo hago, t haces, usted/l/ella hace, nosotros/nosotras hacemos, vosotros/vosotras hacis, ustedes/ellos/ellas hacen ir to go yo voy, t vas, usted/l/ella va, nosotros/nosotras vamos, vosotros/vosotras vais, ustedes/ellos/ellas van poder to be able to yo puedo, t puedes, usted/l/ella puedes, nosotros/nosotras podemos, vosotros/vosotras podis, ustedes/ellos/ellas pueden ser to be yo soy, t eres, usted/l/ella es, nosotros/nosotras somos, vosotros/vosotras sois, ustedes/ellos/ellas son tener to have yo tengo, t tienes, usted/l/ella tiene, nosotros/nosotras tenemos, vosotros/vosotras tenis, ustedes/ellos/ellas tienen Key Takeaways In both English and Spanish, conjugating involves the changing of verb forms to give information about who or what is performing the verbs action and when that action occurs.Spanish conjugation is far more extensive than Englishs, thus providing more information about the verbs action.Conjugating regular Spanish verbs in the indicative present tense involves removing the infinitive ending (-ar, -er, or -ir) and changing it to something else.

Women in Sciences Essay Example | Topics and Well Written Essays - 1250 words
Women in Sciences - Essay Example Other men and women scientists spoke from firsthand experience about the difficulties encountered by women scientists in the past and the present. Participants responded to working papers describing the current state of research on each subject and to an evolving plan for discussion. (Gerhard, 1995) Throughout, the principal objective was to identify questions, ideas, theories, and methods, which might contribute to a new research agenda on the subject of women in science, most likely in biological sciences. Biological sciences, today requires the contribution of modern women to think about the several critical aspects, which are never highlighted in such a manner, as they are highlighted today. Today's women are well aware of those facts due to which the importance of women in the field of "biology" urges women to contribute. The main reason apart from the predominating world of men lies in different aspects relating to women psychology which leads women to think in umpteen ways of criticism, the inferiority complex men has developed within women throughout the nations and the rejection of women appearance in several fields in the past. Today's woman has faced criticism while stepping in Biological sciences in many ways, criticism can be considered from two points of view. (Gerhard, 1995) Criticism, as an activity intimation connected with the pursuit of biology, one that is rendered necessary by the fact that biology is a growing subject, and its growth is not a simple matter of accumulation, but involves frequent readjustment between theory and observation. Women have suffered to be illiterate in the beginning of that era which was governed by men's superiority. Despite of the biological supremacy, which she possesses in the form of delivering not only an individual but also a personality, she has still suffered by not subjecting towards biological sciences. Today's women have understood all the crises for which she was not subjected to biology, so she is now passing a threshold beyond which gender no longer matters in determining career outcomes. Women biologists in this era are doing as well as their male counterparts. Among the younger women in the physical sciences, mathematics, and engineering, for example, the average academic status is almost one full rank below the men's. A partial explanation may be that women have achieved a "critical mass" in biology, where they make up a higher percentage of the population than in physics or chemistry or in any other subject. In addition, the attitudes and behaviors of female and male biologists may have created an atmosphere that is more hospitable to women, thus shrinking the gender gap. (Gerhard, 1995) The current status of women in science is a blend of decisive advance and unfulfilled promise, unfulfilled in the sense that the women in sufferance had always kept on promises for the last two decades, she had always prompted to bear the domination from men with

Internet Usages Affect People's Tourism Booking And Decision-making Essay
Internet Usages Affect People's Tourism Booking And Decision-making - Essay Example This report stresses that most people prefer internet travel planning and booking due to its efficiency. It offers more information and costs lesser than a travel agency. It also has no time limit for information search and one can see videos or movies of the chosen destination. The internet is also non-stop available hence one can access the information from anywhere with internet access. One can compare offers quickly and at the same time find opinions of other persons since the internet provides some degree of freedom. This paper makes a conclusion that internet travel planning and booking also has its disadvantages. The website is not able to distinguish between cheap and best value ,for example a room may be deemed as cheap whereas it does not fit the clientââ¬â¢s expectations. The internet websites do not understand the clients. The client often does not know what they are getting themselves into. Unlike a travel agent who can know what the client can and cannot put up with, the internet is not able to know. The internet websites are also not proactive. This implies that they do not understand the clients and they do not offer the best value but just raw price. Websites cannot be able to look into the whites of the eyes. An agent can use their skills to read an itinerary, to understand it, analyze any real issues and then communicate them to the client. This study shows that an increasing number is turning to social media to help them with the research.

Categorisation in Long-Term Memory Essay Example for Free
Categorisation in Long-Term Memory Essay The method used was a field experiment as it took part in a classroom. This method was chosen because the independent variable can be manipulated to find the effect on the dependent variable, which can draw conclusions about cause and effect. Doing this allows reasonable control of extraneous variables and where the experimenter has a significant amount of control. An independent groups design was most appropriate because it prevents order effects and demand characteristics to a certain extent. There will be two groups, a control group who will be shown a random list of words and an experiment group who will receive a categorised list. This enables me to compare the number of words each group can recall and therefore claim the cause and effect. Independent variable Whether participants are presented with an organised list of words or not. Dependant variable Memory as measured by the number of words the participant recall from the list of words. Participants It was an opportunity sample of International school students from 13 to 14 years old. 10 participants were allocated into each condition randomly (condition 1: control group who received a random list of words, condition 2: experiment group with an organised list of categorised words). Each condition had 5 females and 5 males. Anyone that was available was asked if they would take part in the experiment. None of the participants dropped out and only 2 students refused to take part, because they were not free at that moment. This sampling method was chosen because it was quick and convenient. By using independent designs, some extraneous variables were controlled. Order effects were prevented since different participants were allocated in different conditions. Having clear and concise standardised instructions reduced confusion. The procedures were standardised to reduce any experimenter effects. The room was kept in a constant temperature to reduce it from possibly affecting participants memory. Students were ranged from 13-14 years old. Other noise from outside the room may have distorted the results and therefore all windows and doors were closed so that as little noise as possible was allowed into the room. The group of participants who received the organised lists of words recalled more words than the participants with the randomly categorised list. It was distinctive from the graph that people given categorised words recalled more words than people who received a random list. The results support my hypothesis of better recall from students if words were categorised. The relationship between the independent and dependant variable was if the words were categorised, the higher the recall. Discussion Validity Validity is if the measuring apparatus measures what its meant to measure. By looking at the number of words remembered, its an indicator of memory as it is clear that the more words you recall the more words were remembered, this is called face validity and its purpose is to see if the experiment is testing what its supposed to measure. I chose 3 categories of words to use in my experiment and I think that they were the correct categories to use as they were all only 1 syllable and are generally used in everyday life. This is related to construct validity which is whether the method can be used to support the variable that is being measured. (If the experiment was replicated, we would see similar results) I think that I chose the words that best measure organisation and that my test was valid. Ecological validity is if the experiment measures a naturally occurring behaviour. This was a field experiment which has good ecological validity but its not usual for someone to be taken into a room and to participate in a test on a daily life setting. The participants were aware they were taking part in a psychology experiment so the results could have been affected by demand characteristics. Suggestions for improving validity Participants were aware they were talking part in a psychology experiment which could have created demand characteristics and possible experimenter bias. To obtain a higher ecological validity I could have applied my study to school/everyday life. For example, asking participants to recall a list of ingredients that they had used to bake a cake. This could prevent demand characteristics and experimenter bias as participants might not be aware this that it is a psychology experiment and could possibly make my results more valid. Doing this however, would make it harder to control any extraneous variables and the study would be more difficult to replicate and standardise. Reliability Reliability is whether the measuring method can measure consistently. If the experiment was repeated, similar results would appear. I have increased reliability using the same words in both lists. Two different lists of words decreases reliability as some words are easier to remember than others. Therefore using the same words will reduce this effect. In the list of organised words it was obvious that the experiment was testing memory which led to demand characteristics. The experiment were standardised which meant its easy to replicate. However, because participants were already told that they were taking part in a psychology experiment on memory, they knew what the experiment was about and could try harder to perform better on the test (demand characteristics). Improving reliability If I were to choose a different sampling method results would be much more representative, because my sample was an opportunity sample with only people who were free at that moment. I could have chosen a random sample to increase reliability since there are different levels of cognitive abilities in students and not only people who were free. This method could be done by picking 10 males and females randomly (picking out names from hat) from each year group. This means a total of 70 subjects would be used instead of just 20 and doing this would give me more reliable results and a much more representative sample of school students. Also, to reduce demand characteristics the purpose of the experiment shouldnt have been told to the participants until after the experiment, which is called debriefing. Implications of study Bousfield found that we have semantic organisation in our long-term memory. Bower et al found that organising words into a categorised hierarchy would help to improve recall. In this study I found that participants recalled more words when the words on this list were organised. This means that the findings of my experiment support both Bowers and Bousfields findings. This implies that there is in fact a short and long-term memory and that there is some kind of semantic organisation of the information in the long-term memory which can improve peoples re-call. Generalisation of findings Target population is the age and group of people an experimenter plans to generalise their findings on. In my experiment the target population was Island School students between the ages 13-14 years old. This was hard to generalise due to the sampling method. The method was biased because only students who were available and around at that time were asked to participate. This could be improved if a larger sample of students were used and not only people who were free to participate. My experiment only involved 20 people, which was too little to generalise a school of 1500 students. It was hard to generalise beyond the target population, as there are individual differences, psychological differences and cultural differences between much of the population. In addition my sample was too small to generalise beyond target population. Applications of everyday life It was found that an organised list of categorized words would be more efficient to remember than a randomly placed list of words. This can be applied to everyday life, for example when teachers teach children they have to teach in a systematical order so it is easier to recall the majority of information. As for a high school there is a syllabus which is organized by categorising the same type of information together. This is the most efficient way for remembering information and recalling it for exams.

Economic Policy Essay -- essays research papers
Economic Policy in Recent U.S. History In the highly materialistic world that we live in, success is generally measured in financial terms. The same is true in politics, where the success of a politician, especially the President, is measured by how well the economy did during his term in office. It is specifically measured by how well they bring down unemployment, grow the economy and fight inflation. Two basic modes of thought on the subject have pervaded public policy since World War II: supply-side and demand-side economics. Demand-side economics is generally known as Keynesianism, named after the English economist John Maynard Keynes. He believed that governments should force interest rates down by printing money and lending it from the central bank at a discount. This would put more money in consumers\\\' hands and encourage them to spend and consume more, thus creating an incentive for investment. This helped to solve some of the problems, but in the long run it is extremely inflationary, because with the increase of the money supply it becomes devalued. Keynesianism also calls for the government to spend more to try to help the economy grow. Keynesianism was a short-term solution to the problem and could only do so much for the economy before inflation caught up with it, and took it into recession. On the other hand we have supply side economics, which works on more of a long-term basis. It basically attempts to stimulate economic growth, which would reduce inflation, and raise the standard of living. Supply side proponents say that by reducing government regulations and taxation, this will stimulate more economic growth, and market equilibrium will be reached on itââ¬â¢s own, without government impositions. Keynesianism was popular until the late 1970ââ¬â¢s during a period of ââ¬Ëstagflationââ¬â¢, where both unemployment and inflation were rising together. Policymakers realized that they could not solve this problem with Keynesian ways of thought. When Reagan came into his Presidency he was faced with an economy that was in recession; the prime interest rate was 15à ½ percent, the unemployment rate was over 7 percent and inflation was running close to 14 percent a year. Reagan and his advisors took a conservative approach to solving the problem and looked to supply-side, or ââ¬Ëtrickle downââ¬â¢ economics to accomplish their goal of bringing the country out of this... ...ngress in fact adopted the tax reductions, and a set of spending reductions was incorporated into the First Congressional Budget Resolution. The budget process for 1982 was never completed, however, and the 1981-82 recession intervened. The net result of these efforts has been that tax rates are lower now than in 1980, but not lower than rates in 1979. The reductions in aggregate federal expenditures relative to GNP, however, have not materialized. Indeed, during the first three years of the Reagan administration, federal spending as a percentage of GNP increased to historically high peacetime levels. Because the decline in the rate of growth of tax revenues has not been matched by a decline in the growth of expenditures, the government\\\'s budget deficit in real terms has also reached unprecedented peacetime levels. The 1983 deficit was almost 6 percent of GNP. Projected deficits for 1985 and 1986 exceed 4 percent of GNP. These levels are of the same order of magnitude as those reached during the Great Depression of the 1930s. Without a reversal of the tax reductions or significant real spending cuts, the projected deficits will not fall below 3 percent of GNP until 1989.

Quantitative Determination of Sulfate by Gravimetric Analysis Essay
1. Synopsis: This report is written about determining the quantitative amount of sulphate inside barium sulphate, BaSOâââ, using the method of gravimetric analysis. This quantitative determination is done by the addition of a dilute solution of barium chloride slowly to a hot unknown sulfate solution slightly acidified by concentrated hydrochloric acid, HCl. The white precipitate of barium sulphate is filtered off, washed with water, oven-dried, and weighed as barium sulphate. The quantitative amount of sulphate is deduced from mathematical calculations. The results of the experiment, however, did not yield positively, probably due to inadvertent human error over the course of the experiment. The percentage yield of sulphate inside barium sulphate attained from our results was not up to expectations. The percentage yield of sulphate was expected to be at least 90% and above, with >90% as a good percentage yield. Instead, we attained 54% percentage yield of sulphate. 2. Objective: The purpose of the experiment is to determine the quantitative amount of sulphate inside barium sulphate using the method of gravimetric analysis. 3. Theory: 3.1 Summary: Throughout the duration of the experiment, there are many procedures, techniques, chemicals, and instruments used to produce the results of the experiment. There are a total of three simple sets of procedures required, in the gravimetric analysis method, in order to create the results of the experiment. The first procedure is the precipitation of BaSOâââ, barium sulphate, followed by the second procedure, the washing and filtration of BaSOâââ precipitate. The third and final procedure is the drying and weighing of the dry sample of BaSOâââ precipitate. From there, the results are gathered by methodical mathematical calculations. 3.2 Technique: Gravimetric Analysis: Gravimetric analysis is a series of methods in analytical chemistry for finding the quantitative amount of a certain analyte based on a sample of solid. To perform gravimetric analysis, one of the most common methods is to convert the analyte into a solid via the use of precipitation with the appropriate reagent chemicals. After that, the precipitate is collected via filtration, washed, dried, off all moisture content, and weighed. Then, the quantitative amount of analyte in the sample is calculated from the mass of the precipitate and its chemical composition. There are many advantages using gravimetric analysis. It allows for extremely precise analysis, such as the determination of many elementsââ¬â¢ atomic masses up to six decimal places. It also does not require expensive scientific equipment to perform such analysis and, furthermore, it can even be used to calibrate scientific instruments in lieu of international reference standards. 3.3 Chemicals: During the experiment, some chemicals were used to obtain the barium sulphate, BaSO4, from which the quantitative amount of sulphate can be found from within. The chemicals used were dilute 10% barium chloride solution, BaCl2, dilute 0.5% sodium sulphate solution, (Na)2SO4, and concentrated hydrochloric acid solution, HCl. In order to obtain barium sulphate, a chemical process, known as the displacement reaction, was utilised. In the displacement reaction, the cations and anions switch places from their original compounds to form entirely different compounds. In this experiment, 10% barium chloride solution is added to 0.5% sodium sulphate solution (which is slightly acidified by adding concentrated hydrochloric acid), resulting in the formation of soluble barium sulphate. 3.4 Instruments: In the experiment, various scientific instruments were used in the determination of the quantitative amount of sulphate. The following instruments were used, were the 250ml beaker, the bulb filler and vacuum-assisted pipette, the measuring cylinder, the watch glass, the laboratory crucible, the vacuum pump, the hot air oven, the desiccator, and the digital analytical weighing balance. The 250ml beaker is a cylindrical container with a flat bottom, which is used as a simple container to stir, heat, or mix various liquids. The vacuum-assisted pipette is a hollow narrow cylinder that has a large bulge with a single graduation mark as it is calibrated for its specific volume, generally between 10ml, 25ml, and 50ml. The bulb filler is the simplest form of the pipette dispenser, using pinch valves to draw air within to create a vacuum within the vacuum-assisted pipette. The two pieces of laboratory equipment are generally used in conjunction with one another. The bulb filler is carefully inserted on top on the vacuum-assisted pipette. The pinch valves can be manipulated to draw the liquid inside the pipette. The measuring cylinder is a narrow cylinder with a flat base that is used to measure amounts of liquid with the corresponding markings along the cylinder. The watch glass is a circular, slightly convex-concave piece of glass that is generally used to evaporate a liquid, hold solids being weighed, or as a cover for the beaker. The laboratory crucible is a cup-shaped piece of laboratory equipment made to contain chemical compounds as they are heated to extremely-high temperatures. The hot air oven is an electrical oven used to dry chemical compounds or sterilise articles. The desiccator is a sealable enclosure that is used to preserve items sensitive to moisture in the open air, such as cobalt chloride paper. The digital analytical weighing balance is type of electronic balance made to measure small amounts of mass up till several decim al figures. 4. Procedures: In order to determine the quantitative amount of sulphate, the procedure that is split up into three smaller sections. The first section is the precipitation of barium sulphate. The second section is the washing and filtration of the barium sulphate precipitate. And, the third section is the drying and weighing of the barium sulphate precipitate. 4.1 Precipitation of BaSO2: 1. Use the bulb filler and vacuum-assisted pipette to pipette 25ml of the 0.5% sodium sulphate solution into a 250ml beaker. 2. Add 50ml of water and 5 drops of concentrated hydrochloric acid into the beaker. Note: Concentrated hydrochloric acid is highly corrosive. Add the concentrated hydrochloric acid into the beaker while handling it in the fume hood with protective gloves and goggles. 3. Heat the beaker until it is boiling. Use a glass rod to stir the solution vigorously, while adding 10ml of 10% barium chloride solution from a measuring cylinder drop-by-drop. 4. Use a watch glass to cover the beaker and adjust the heat to just below temperatures. Leave it there to digest for 20 minutes. 5. To test for complete precipitation, add a few drops of barium chloride and observe to see if there is clear supernatant liquid. 4.2 Washing and Filtration of BaSO4 Precipitate: 1. Take two pieces of filter paper and place them at the base of the dry and weighed laboratory crucible. Ensure that the filter paper pieces cover the base of crucible completely. Then, use the vacuum pump to decant the clear supernatant liquid by filtration into the crucible. 2. Dislodge any particles in the beaker and rinse it with warm deionised water. Empty the contents into the crucible while the vacuum pump is at work. Make sure that all the solids in the beaker have been transferred to the crucible. 3. Wash the barium sulphate precipitate further with warm deionised water at the vacuum pump twice more. 4. Discard the filtrate. 4.3 Drying and Weighing of BaSO4 Precipitate: 1. Place the crucible, containing the BaSO4 precipitate, into the hot air oven. Set the temperature to 150à °C and leave it for half an hour. 2. Use the desiccator to cool the crucible and precipitate for 10 minutes. 3. Once the crucible has cooled down, weigh it using the digital analytical weighing balance. 4. The weight of the BaSO4 precipitate is calculated from the difference between this weight and the weight of the empty crucible including the filter papers. If there is still sufficient time, you may repeat the above Steps 1-4 until a constant weight of the precipitate is successfully obtained. 5. Results and Calculations: | 1st Drying:| 2nd Drying:| Mass of Crucible + Filter Paper + Sample:| 31.9078g| 32.0188g| Mass of Crucible + Filter Paper:| 31.7975g| 31.9071g| Mass of Sample (BaSO4):| 0.1103g| 0.1117g| The mathematical calculations to attain the results of this experiment are listed below: 0.5% of sodium sulphate (NaSO4) = 5100 Ãâ"25g = 0.125g Composition by mass of SO42- = Molecular weight of sulphate ionMolecular weight of sodium sulphate Ãâ" 0.125 = 0.0845g (4 significant figures) Composition by mass of SO42- prepared = Molecular weight of sulphate ionMolecular weight of barium sulphate Ãâ"0.1103g = 0.04544g (4 significant figures) Percentage yield of sulphate = 0.045440.0845 Ãâ"100% = 53. 775% ââ°Ë 54% 6. Discussions: The objective of this experiment was to determine the quantitative amount of sulphate using the gravimetric analysis method. The quantitative amount of sulphate was measured in percentage yield, which we attained 54% instead of the expected percentage yield of 90% and above. It became obvious that somewhere along the way, in conducting the experiment, a significant error had been committed. After much analysis, it was found that there had been some sources of error that accounted for the less-than-satisfactory results. One major source of error could be the contamination of the intended precipitate through the use of laboratory instruments and vessels that were not cleaned properly. When the instruments and vessels are unclean, any left-over remains of chemicals and compounds could be unintentionally released to the intended precipitate and polluted it through a process known as co-precipitation. The foreign species could have reacted with the intended precipitate and resulted in the loss of much of the sulphate ions, leaving only 54% instead of the intended 90% and above. To avoid any possible error of contamination, one must keep in mind to properly clean the instruments and vessels to use in the experiment. One way to minimise the co-precipitation of substances would be leaving the solution, containing the soluble precipitate of barium sulphate, in the process of forming the precipitate, to digest longer than the standard 20 minutes. Another source of error could be the decomposition of the precipitate itself during the process of removing moisture content in the hot air oven. The ignition can result in the losses via decomposition of the potentially-volatile precipitate. 7. Conclusion: In conclusion, the results were not up to expectations due to a few sources of error that caused the less-than-satisfactory results. Gravimetric analysis is a proven set of methods to use in the field of analytical chemistry. It allows for extremely precise results, if the procedures were followed very carefully, and no errors were committed over the course of the experiment. However, we did not attain 90% and above for the percentage yield of sulphate as we committed some errors unknowingly. Contamination was a major issue in the experiment that would have been avoided if only we had properly cleaned the instruments before performing the experiment. In short, the objective of the experiment was fulfilled by attaining sulphate using the gravimetric analysis method, although not all of it was attained. 8. References: Online References: Theory: 1.

A Strategy To Align Organization And Environment Essay
This paper analyzes the term ââ¬Ëstrategic fitââ¬â¢ exactly means, types of strategic fit, necessities to focus on strategic fit, and most importantly how well an organization can align its resources & capabilities with the opportunities that exist in the external environment so as to achieve peak performance in the business. Strategy of Nestle as an example to discuss how far it is true that effective strategic fit ensures organizationââ¬â¢s resources & capabilities and what the environment exactly needs from it. Key Words Strategic, Fit, Strategy, Resource, Capabilities, Opportunities, Environment, Business Introduction It should be recognized that any strategy or management style is appropriate only in a particular set of circumstances. Strategic fit enables an organization to operate in its particular competitive situation at peak effectiveness. It expresses the degree to which an organization is matching its resources and capabilities with the opportunities in the external environment. The matching takes place through strategy and it is therefore vital that the company have the actual resources and capabilities to execute and support the strategy. Meaning of Strategic Fit The contingency theoristââ¬â¢s argument that performance outcomes are maximized when a firm achieves an alignment or ââ¬Å"fitâ⬠between a firmââ¬â¢s external environment, its internal factors and its strategy has been well established in the literature (Burns & Stalker 1967; Lawrence & Lorsch 1967; Keats & Hitt, 1988). Nadler and Tushman (1979) theorized that the greater the total degree of congruence or fit between the various components, the more effective will be the organization, leading to higher levels of goal attainment, utilization of resources, and adaptation. Need for Strategic Fit Strategic fit is a quest to align the organizationââ¬â¢s operation with the needs of the market. It also involves identification of the opportunities and the action to capitalize on the opportunities. Strategic fit can be used actively to evaluate the current strategic situation of a company as well as opportunities such as M&A and divestitures of organizational divisions. Strategic fit is related to the Resource-based view of the firm which suggests that the key to profitability is not only through positioning and industry selection but rather through an internal focus which seeks to utilize the unique characteristics of the companyââ¬â¢s portfolio of resources and capabilities. Resources s Capabilities A unique combination of resources and capabilities can eventually be developed into a competitive advantage which the company can profit from. However, it is important to differentiate between resources and capabilities. Resources relate to the inputs to production owned by the company, whereas capabilities describe the accumulation of learning the company possesses. Types of Resources Resources can be classified as tangible resources and intangible resources. Tangible Resources The term tangible means capable of being touched, real or actual, rather than imaginary or visionary, definite; not vague or elusive, having actual physical existence, as real estate or chattels, and therefore capable of being assigned a value in monetary terms. Financial (Cash, securities) â⬠¢ Physical (Location, plant, machinery) are some of the tangible resources Intangible Resources Resources that are not physical in nature are said to be Intangible resources. Corporate intellectual property (items such as patents, trademarks, copyrights, business methodologies), goodwill and brand recognition are all common intangible resources in business point of view. An intangible resource can be classified as either indefinite o r definite depending on the specifics of that resource. A company brand name is considered to be an indefinite resource, as it stays with the company as long as the company continues operations. However, if a company enters a legal agreement to operate under another companyââ¬â¢s patent, with no plans of extending the agreement, it would have a limited life and would be classified as a definite resource. â⬠¢ Technology (Patents, copyrights) â⬠¢ Human resources â⬠¢ Reputation (Brands) â⬠¢ Culture, are some of the intangible resources. Capabilities Capabilities are what a firm does, and represents the firmââ¬â¢s capacity to deploy resources that have been purposely integrated to achieve the desired end state. Capabilities become important when they are combined in unique combinations which create core competencies which have strategic value and can lead to competitive advantage. Capabilities needed for strategic fit are 1. Coordination 2. Commitment 3. Competence (technology, management and leadership) 4. Communication 5. Creativity 6. Capacity management (allocation of resources) Benefits of Strategic Fit The extent to which the activities of a single organization or of organizations working in partnership complement each other in such a way as to contribute to competitive advantage. The benefits of good strategic fit include cost reduction, due to economies of scale, and the transfer of knowledge and skills (technological expertise, managerial know how), use of common brand name. The success of a merger, joint venture, or strategic alliance may be affected by the degree of strategic fit between the organizations involved. Similarly, the strategic fit of one organization with another is often a factor in decisions about acquisitions, mergers, diversification, or divestment. Types of Strategic Fit 1. Market related fit 2. Operating fit 3. Management fit Market Related Fit Market related fit arises when value chains of different businesses overlap so that the products can be used by same customers, marketed and promoted in similar ways, distributed through common dealers and retailers.

The Negative Impacts Of Cruise Tourism Tourism Essay Essays
The Negative Impacts Of Cruise Tourism Tourism Essay Essays The Negative Impacts Of Cruise Tourism Tourism Essay Essay The Negative Impacts Of Cruise Tourism Tourism Essay Essay 1. Introduction Presents, cruise touristry plays an of import function in the touristry industry. Cruise ships become newer, larger and more comfy so that about every demand of the clients can be satisfied on the high seas. Capabilities like theatres, film, fittingness nines, discotheques, casinos, tennis tribunals and many others are common on most modern sail ships. Furthermore, that most of the named activities are already included in the monetary value. Thereby the ships beat about all the seven oceans to the most beautiful topographic points on Earth like for case the Caribbean. But all these glorious sounding characteristics involve several negative environmental jobs. Cruise ships pollute the seas with dozenss of waste and sewerage which causes lessenings of biodiversity, coral reefs and of class the H2O quality. Mass touristry injuries and destroys ecological systems like beaches and reefs. This scrutiny is about the impacts of sail touristry to the environment and contingencies how to do cr uise touristry more sustainable. 2. Use of resources Cruise touristry requires an copiousness of resources and produces measures of waste. A typical Caribbean sail ship produces about 50tons of waste, 7.5 million litre drinkable H2O, 800.000 litre effluent and 130.000 litre oleiferous H2O. Approximately 75 % of all produced effluent are caused by sail ships. Between 1993 and 1998 over 100 instances of marine pollutions were investigated in the Caribbean. The estimation figure of unknown instances might transcend this figure many times over because the disposal of effluent takes topographic point in aquatic environments where environmental pollution is permitted on payment of a fee. Furthermore the sail industry requires a convenient super- and substructure at their finishs which frequently overwhelms the fiscal capableness of the parts and causes a dependence to the sail touristry. 3. General information about the impact of the sail touristry industry The full touristry industry has positive every bit good as negative impacts on the economic system, the civilization and the environment. Thereby the sail industry is no exclusion. Bing an in Niche market the sail industry s impact is higher-than norm. By set uping more than 450,000 employments with wages of 15 billion US-Dollars in the whole and a turnover of some billion dollars above all the sail industry in the USA has a great impact on the economic system. Furthermore a large impact on the authorities s grosss and outgos is noteworthy. The grosss of local authoritiess consist like followers: Taxes paid on turnovers by sail rider, the crew and the sail line Temporarily revenue enhancements on adjustments that are paid by riders Grosss in fees paid by riders every bit good as by the sail line, including fees for naming at a port, cleansing and other outgos on a seaport Fees for recycling and the usage of H2O Fees for riders, including admittance charge and payments for medical proviso Tax payment of companies which distribute merchandises and services to cruise lines riders revenue enhancements paid by endeavors Operational costs on- site Secondary or indirect revenue enhancement grosss like payment of belongings revenue enhancement by employees of the sail lines and their households 4. Possibilities to make sustainable sail touristry The Cruise touristry encompasses different sections and sub sections. Aspects of sustainability in the sense of ecological sustainability drama in most of the sub-segments of sail touristry a more or less of import function. All indicants are that the sail industry, in its ain involvement, tries to extinguish these negative impacts every bit fast as possible. Potential Reasons, as the fact that one of the most of import subareas of sail industry, the Caribbean, can non follow the construct of sustainable touristry in the sense of the definition of sustainability mentioned in the Bruntland Report, have to be searched on the academic and socio-cultural degree. To happen concrete grounds on these degrees seems to be hard. Although the sail touristry novice doubtless economical urges on the finishs, the basically effects on the long term local development remain to be unfulfilled. The relation between costs and benefits on the environmental degree every bit good as on the socio- cultural degree seems to be unbalanced what a disadvantage of the finishs is. A quantification of this context owes. With the undersigning of a pioneering nature protection understanding on January 15th 2008, re-experienced the 12-month coaction of Conservation International, the touristry bureau of Cozumel, and the Florida-Caribbean Cruise Association its flood tide. Cruise industry representatives from the authorities, private endeavor association and cruise ship association were portion of this contract. With the undersigning of this agreement the contractual spouses originated a important nature conservancy enterprise which should assist to protect the vulnerable biodiversity of the most popular sail finish on Earth Cozumel, Mexico. In the twelvemonth 2006 the island employed about 1000 workers for sail ships, which brought an estimation figure of 2.6 million sail riders to Cozumel. During extremum times up to nine sail ships with over 10.000 tourers reach the island s harbor day-to-day. The rapid growth of the sail touristry industry led to a heavy load for the environment. The understanding composes the basis for sustainable sail touristry which will be achieved with the undermentioned undertakings: The creative activity of more consciousness for environmental jobs among the sail tourers, circuit operators and within the local community Improvement of the substructure of the island ( particularly the transportation- and waste-management ) Increased security for the coral reef Indemnity of the rigorous observation of current Torahs These undertakings were developed during a scope of workshops by groups of different stakeholders. Hereby over 80 taking representatives of the sail touristry were brought together in order to nail of import environmental facets and to accomplish a common achievement for these undertakings. This common planning procedure is worldwide the first of its sort in the sail touristry. Therefore Cozumel is the lone sail ship finish which helps to forestall its nature and biodiversity. Leading representatives of the sail touristry established the alleged Stewardship Working Group which is supposed to implement aims mentioned in the environment protection understanding. Following aims are on the docket: Every sail ship rider will see a 30 2nd information-movie in which he will appealed to manage sustainable in order to protect the nature In a exposure exhibition, nearby the landing phase, the riders will see the good territories of the island All tour-boats on the island have their ain recycling system In the following measure the representatives will germinate consciousness runs which involve non merely the sail tourers but besides the circuit operator and hosts. Approximately over 500.000 sail tourers will be involved in such runs. 5. Particular sensitive sea country The sail industry will be confronted with several challenges related to environmental issues in the hereafter. These challenges relate to the activities in the oceans, particularly in and around of import nature protection countries. The international Maritime Organization ( IMO ) recognized that issue and initiated neutralizations, the so called Particular Sensitive Sea Areas ( PSSA ) . At present there exist 11 PSSA s. The effectual guidelines of these countries commit all the authoritiess of the IMO member- provinces to guarantee that sail lines which drive under their flag have to maintain the methods of protection. The following 11 PSSA s were arranged: The Great Barrier Reef, Australia ( 1990 ) The Sabana-Camag A ; uuml ; ey Archipelago, Cuba ( 1996 ) The Malpelo Island, Colombia ( 2002 ) The Sea around the Florida Keys ( 2002 ) The Wadden Sea, Denmark, Norway, Germanys ( 2002 ) The Paracas National Reserve, Peru ( 2003 ) The western European Waters ( 2004 ) Expansion of the bing PSSA of the Great Barrier Reef including the Torres Strait Islands ( 2005 ) The Canary Islands, Spain ( 2005 ) The Galapagos Archipelago, Ecuador ( 2005 ) The Baltic Sea, Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland and Sweden ( 2005 ) The MARPOL Convention arranges three complementary methods for the taint direction: Decrease of waste merchandises, Recycling and disposal of waste. With the understanding of the MARPOL Convention a sail ship can change over its waste and dispose it on its ain every bit good as leave the waste on a seaport for disposal either by shop it, fire it or recycle it. 6. Surveies and scientific literature In the more recent past merely a little figure of surveies refering the environmental impact of the sail industry existed. For a considerable clip a broad scope of articles, studies, books, runs and web sites occurred. The most enlightening subscription are scientific plants ( Cruise Ship Tourism, 2006, CABI ) , which interpret the concrete impacts of the sail industry to the environment. The most considered researches were published by Ross Dowling and Ross Klein ( Cruise Ship Blues The Underside of the Cruise Industry, 2002, and Cruise Ship Squeeze The New Pirates of the Seven Seas, 2005, New Society Publishers ) . Furthermore, Klein besides operates to web sites ( www.cruisejunkie.com and www.cruiseresearch.org ) where the visitant can happen a varies figure of resources like elaborate lists of diseases, cancellations, self-destructions, riders who fell overboard, powertrain jobs, environmental incidents, wellness issues and many more. Between 2002 and 2006 over one 1000 facts were collected. 7. Decision Although the sail touristry has a immense negative impact on the environment there are still no homogeneous ordinances or Torahs to protect the ecological system. Even if some parts established such Torahs, ordinances and awareness runs there are still immense countries of freedom to move in an environmentally harmful manner. Due to the magnitude of the seas the direct environmental impacts are non clearly recognizable in a short clip but they cause long-run amendss. The new sail ships which are bigger than of all time before and the increasing demand in this touristry subdivision wo nt assist to come to grips with this job. In footings of accomplishing sustainable touristry it is, hence, a sub-sector within which socio-economic, cultural and environmental considerations need to be continually analyzed, addressed and monitored. However, decision-makers in sail touristry finishs, peculiarly those outside North America, demand to work closely with operators to ease both integrated waste direction and intergenerational and intra-societal equity instead than simply accept the chance of short-run economic addition.
