International criminal court - Essay Example There are several reasons for this inability of national institutions, such as, first, the absence of political will to prosecute their own citizens or high ranking officials. This situation was witnessed in the former Yugoslavia. Second, these national institutions could have been destroyed, as was the situation in Rwanda. In the absence of justice there cannot be peace, without law no justice, and when there is no court to decide what is just and lawful there can be no meaningful law (United Nations, 1999). An international criminal court achieves justice for all, ends impunity, helps in ending conflicts, remedies the defects in ad hoc tribunals, provides an alternative to national criminal justice institutions that are unable or unwilling to act, and to acts as a deterrent for future war criminals. In reality, the ICC has not achieved greater success than the ad hoc tribunals that it supplants. Akin to the tribunals of Rwanda and Yugoslavia, the ICC does not act swiftly. Moreover, it is devoid of a system for enforcing its decisions. This makes it dependent upon governments to arrest and present perpetrators before it. Albeit, the ad hoc tribunals had this defect, they were able to rely on a UN Security Council resolution requiring international cooperation in executing the arrest warrants. In addition, the ICC is devoid of forceful checks on its authority (Schafer & Groves, 2009). Theoretically, the nations that had ratified the Rome Statute were to control the ICC; however, this has not been realized in practice. Schafer, B. D., & Groves, S. (2009, August 18).

How Does IT Influence Business Essay Example | Topics and Well Written Essays - 1250 words

How Does IT Influence Business - Essay Example Laudon &Traver (2002) therefore explains that information technology plays a role in the manner which companies and business organizations are able to communicate market and accomplish their objectives. Specialized information technologies normally plays a role in shaping the best business practices that an organization needs to pursue, and hence plays a role in shaping the face of business on a daily basis. It is important to understand that information technology has played a role in improving the quality of business operations. Information technology increases the productivity of an organization, because of the use of computers and other tools of IT. The use of computers has played a great role in transforming the work environment. It has played a role in driving the costs of processing data, and improving the capability of an organization to store and disseminate large volumes of data, which are of great importance to the company (Laudon &Traver, 2002). The internet enables an organization to transfer these information from one department to another, and to customers. Take for example the electronic health registers that are implemented by hospital organizations in the United States. Electronic health registers have improved the manner which business organizations are able to store and disseminate the information under their possession (Laudon &Traver, 2002). This information can include the name of the patient, his or her medical condition, and their medical history. Private hospital organizations have a chieved in the use of electronic health registers to treat their patients. This is because they are able to share this information with doctors, and other people responsible for handling the patient (Tansey, 2003). This in turn leads to an accurate diagnosis and a reduction in the readmission cases. Furthermore, information technology has played a role in improving the internal operations of a business organization. This

Periodic Properties Essay The halogens F, Cl, Br and I (At has not been included because of its scarcity and nuclear instability) are very reactive non-metals that occur in the penultimate group of the periodic table, hence they all require just one electron to complete their valence shell. All of the elements exists as diatomic molecules (F2, Cl2, Br2, I2) in which the atoms are joined by single covalent bonds. Going down a group of the periodic table, for successive elements there are more energy levels filled with electrons, so the outer electors are in higher energy levels and farther from the nucleus. Fluorine and chlorine are gases, bromine a liquid and iodine a solid that forms a purple vapour on heating. The halogens are all quite electronegative elements. They require just one electron to complete their valence shell, hence they readily gain electrons to form the singly charged halide ions (Fà ¯Ã‚ ¿Ã‚ ½,Clà ¯Ã‚ ¿Ã‚ ½,Brà ¯Ã‚ ¿Ã‚ ½,Ià ¯Ã‚ ¿Ã‚ ½). The ease with which they gain electrons gained is further from the nucleus and hence less strongly attracted. This means that, in contrast to the alkali metals, the reactivity of the halogens decreases going down the group. Method 1) Test the solubility of Iodine: 1. A very small amount of iodine was put into water, cyclohexane and KI(aq) respectively 2. The color changes of the solutions and the solubility in each solvent were recorded 2) Test iodine reacts with starch: 1. Three drops of I2-KI solution were put into a test tube 2. A few drops of starch solution were added after that 3. The color of solution was recorded 3) Test the acid-base properties: 1. A few drops of chlorine water were put in a test surface, and it was tested with universal indicator paper 2. This was repeated first using water and then using iodine solution instead of the chlorine water 3. The color changes were recorded 4) Displacements between halogen elements: 1. 2cm depth of each aqueous solution: sodium chloride, potassium bromide and potassium iodide were put into 3 respective test tubes and labeled 2. An equal volume of chlorine water was added into each test tube and the results were recorded 3. A little hexane was added to form a separate upper layer of a non-polar solvent 4. The mixtures were shook and the changes were recorded 5. Step 1, 2, 3 and 4 were repeated first using water and then iodine solution instead of chlorine water 5) Tests for halide ions [Halide ions (Cl-, Br- and I-) with silver ions]: 1. About 1cm depth of aqueous sodium chloride was put into a test tube 2. A little aqueous silver nitrate was added and then the observations were recorded 3. The test tube was placed in a sunny place, and left there for about 5 minutes and then it was observed again 4. Step 1, 2 and 3 were repeated using aqueous potassium bromide, then aqueous potassium iodide instead of sodium chloride ?Data Collection? 1) The solubility of iodine in different solvent Color Solubility Water Colorless Insoluble Cyclohexane Purple Soluble Ethanol Yellow Soluble KI(aq) Yellow-brown Soluble 2) Test iodine reacts with starch: The color of the solution is black. 3) Test the acid-base properties: Cl2 Br2 I2-KI pH value 4 3 12 4) Displacements between halogen elements: The color change of the solution after Cl2, Br2, I2 added into NaCl, KBr and KI respectively Cl2 Br2 I2 NaCl No change No change Brown KBr Pale yellow solution No change Brown KI yellow yellow Brown The color of the upper layers of the solution after hexane added Cl2 Br2 I2 NaCl No change No change Purple red KBr Pale purple No change Purple red KI purple Pale purple Purple red 5) Tests for halide ions: Halide ions (Cl-, Br- and I-) with silver ions: NaCl White precipitate is produced Darkens after it was placed in sunlight KBr Cream precipitate is produced. KI Yellow precipitate is produced. ?Data Analysis? 1) The solubility of iodine in different solvents: The solubility is larger in non-polar solvent (water, ethanol) and smaller in polar solvents.(cylohexane and KI) The purple color of iodine in cyclohexane is that because in non-polar solvents, iodine froms the violet solution. 2) Test iodine reacts with starch: According to the general knowledge we knew, the phenomenon of this reaction should be blue, but the color observed was black-green. That was because some of the starch hydrolysis in water and produced something could make the color darker. 3) Test the acid-base properties: 1. Cl2: The color of the universal indicator papers showed that Cl2 is strong acid. 2. Br2: The color of the universal indicator papers showed that Br2 is a kind of acid, but not very strong. 3. I2: The color of the universal indicator papers showed that I2 is a strong base. Actually, I2 is acid. The reason is that the original color of I2 is red-brown, that made us cant see the phenomenon clearly. 4) Displacements between halogen elements: As what I mentioned above in background, the rule of displacements between halogen elements is that more reactive ones displace less reactive ones. Thats the reason why Br -cant displace Cl -, and I -cant displace Br and Cl-. When there was no reaction between two elements, the color we observed was the blend of original colors of the less reactive element and the solution containing the more reactive element. If theres a reaction between two elements, the color we can observe is the color of the displaced element. According to the information we got from Internet, we knew hexane is a kind of oil and is insoluble in water-solvent. That was the reason why we could differentiate the two layers of each solution very clearly. The colors of each solutions under layer were the original colors of the saline solutions. There were two kinds of instances of the color of upper layer of each solution. For the solutions those do not have I ion, they were colorless. Thats because hexane is colorless and cannot react with Cl or Br -. Another instance is that the solutions include I -, when I meets hexane, it will show the color of itself. That was why we could observe color of purple in this experiment. 5) Test for halide ions: When halide ions dissolved into silver salts, then the precipitate is appear commonly. The white precipitate is AgCl: AgNO3+NaClà ¯Ã‚ ¿Ã‚ ½AgCl+NaNO3 The off-white precipitate is AgBr: AgNO3+KBrà ¯Ã‚ ¿Ã‚ ½AgBr+NaNO3 The pale yellow precipitate is AgI: AgNO3+NaIà ¯Ã‚ ¿Ã‚ ½AgI+NaNO3 After 10 minutes under the sunshine, photodissociation happened on all of them, so the black precipitate on the bottoms of three test tubes are the products of photodissociation. 1. Going down the group, the elements of this group have the same effective nuclear charge. Atomic radius of these elements becomes bigger because of the increase of the number of energy levels. The attraction between nucleus and valence electrons gets weaker. Less energy is required to remove the first electron from one mole of gaseous atoms. The ionization energy going down the group decreases. The ability to attract electrons becomes weaker. The electronegativity going down the group decreases. 2. Organic solvents always contain the element carbon. Inorganic solvents dont contain the element carbon. The most common solvent, water, is an example of an inorganic solvent. There are many more organic solvents than inorganic solvents. Compare with organic and inorganic solvent, the solubility of iodine is higher in organic solvent. 3. The oxidizing power of the halogens decrease going down the group as the size of the atoms increase going down the group as the size of the atoms increases and the attraction between the nucleus and the electrons becomes less. In that case, going down the group, the elements become less powerful oxidising agents. This means that a higher halogen will displace a lower halogen from its salts. A lower halogen cannot displace a higher halogen from its salts. 4. When starch reacts with iodine, the typical blue black color will appear. Thats a good way for us to identify starch and iodine. 5. After photodissociation, the color of some precipitates will change. will become black. Thats the most obvious one. Other precipitates will become darken. 1. Because we use solid iodine in the first experiment. If we add the solvent into the test tube first, the test tube will be wet and the solid iodine we put in later will attach on the surface inside instead of fall into the liquid. For this reason we must add solid iodine first in experiment 1. 2. According to the first experiment, we found that the solubility of iodine in pure water is very low. But the solubility of iodine in potassium iodide solution is relatively much higher. So we use I2-KI solution to increase the amount of iodine in order to let the phenomenon more obvious.

Vitamin C Content of Apple Juice :: essays research papers

Vitamin C Content of Apple Juice Introduction Complete lack of ascorbic acid (a.k.a Vitamin C) in the diets of humans and other primates leads to a classic nutritional disease, scurvy. This disease was widespread in Europe during the fifteenth and sixteenth centuries, but it is rare today. Ascorbic acid is widely distributed in nature, but it occurs in extremely high concentrations in citrus and green plants such as green peppers and spinach. Ascorbic acid can be synthesized by all plants and animals, with the exception of humans, other primates, and guinea pigs. Therefore, vitamin C must be present in our dietary substances.   Ã‚  Ã‚  Ã‚  Ã‚  The fundamental role of ascorbic acid in metabolic processes is not very well understood. There is some evidence that it may be involved in metabolic hydroxylation reactions of tyrosine, proline, and some steroid hormones, and in the cleavage-oxidation of homogentisic acid. Its function in these metabolic processes appears to be related to the ability of vitamin C to act as a reducing agent.   Ã‚  Ã‚  Ã‚  Ã‚  The adult Recommended Daily Allowance f vitamin C is 70 mg per day. Some scientists and physicians have suggested doses up to 1 to 3 grams per day in order to help resist the common cold. Deficiency of vitamin C results in swollen joint, abnormal development and maintenance of tissue structures, and eventually scurvy.   Ã‚  Ã‚  Ã‚  Ã‚  Determination of vitamin C in biological fluids such as bolld and urine is difficult because only small amounts of the vitamin are present and many interfering reducing agents are present. Substances containing sulfhydryl groups, sulfite, and thisosufate are common in biological fluids and react with DCIP, but much more slowly than ascorbic acid. The interference by sulfhydryl is often minimized by the addition of p-cholormercuribenzoic acid. Materials and Supplies Apple Juice Metaphosphoric acid/ Acetic acid solution 4% Unknown ascorbic acid in metaphosphoric acid/acetic acid solution, .5mg/ml 2,6 dicholorphenolindophenol solution in water Ascorbic acid oxidase, lyophilized water Experimental Procedure Standard Ascorbic Acid Solution Fill a microburet with DCIP solution. Using a pipet, transfer 1.0 ml of the ascorbic acid standard solution to a 50 ml Erlenmeyer flask containing 5 ml of 4% metaphosphoric acid solution. Read and record the initial reading on the buret. Titrate by rapid, dropwise addition of DCIP from the buret while mixing the contents of the flask. Add DCIP solution until a distinct rose-pink color persists for 15-20 seconds. Record the final reading on the buret. Repeat this procedure twice more, each time with a fresh 1.

Should Welfare Recipients Be Drug Tested

Should welfare recipients be drug tested? Welfare is supposed to meet the basic needs and drugs are far from the basic human needs. If drug using recipients get all the benefits they are more likely to take their check and spend it on their next fix, rather than buy groceries. Drug testing welfare recipients would decrease the amount of people abusing the system, it would require recipients to stay free of using drugs, and would reveal recipients who are wasting the tax payers money.It is clear that drug testing welfare recipients would benefit the system, other recipients, and tax payers. Firstly, drug testing would decrease the amount of people abusing the system. People who are drug users and refuse to stop or get help will not apply for welfare. Also, drug testing would send a message to society that abusing the system will no longer be tolerated and it would free up extra funds for families who actually need the help.Thus, drug testing welfare recipients would stop people who ar e abusing of the system. Secondly, drug testing will require recipients to stay free of using drugs. If people really need the assistance money then they will chose to either stay clean or get help to get clean. Recipients who fail the test or simply refuse to take the test will not receive an assistance check and without the welfare money people will not be able to afford drugs. Therefore, drug testing welfare recipients would help clean up illegal drug useLastly, drug testing would reveal recipients who are wasting the tax payer’s money. If the working class has to be drug tested to make their money, those receiving assistance should be drug tested to receive their check. Tax payers should not have to pay for some random person’s drug habit and if people chose to be foolish and want to do drugs they should get a job to support their bad habit. As a result, drug testing welfare recipients would reveal the people who are wasting the tax payer’s money.In conclusi on, qualifying and receiving welfare is a privilege and if the government continues to allow drug users collect welfare payment, this will show that they condone their behavior. Drug testing welfare recipients would decrease abuse to the system, require people to stay clean and reveal people who are wasting the tax payer’s money. The government should pass the law to drug test welfare recipients. Hard working, taxpaying citizen’s money is going towards helping people get back on their feet using the welfare system, and far too often people are abusing the system to pay for and support their drug habits.

Early Childhood Activity Essay

During the course of the years it has been noticed that physical, emotional, and mental levels of 6-9 year old children undergo various stages. It is especially obvious for their teachers and coordinators that possess external evidence about the kids and have ability to truly evaluate them. Unlike teachers and supervisors, parents oftentimes try to justify the decisions and deeds of their small kids and make attempts to â€Å"smooth the edges† to avoid potential conflicts due to their feeling they naturally experience towards their children. Therefore, the representatives of next generation behave differently at home and other social environments like school that include numerous exciting activities useful for children while opening new horizons. The early childhood activity indicated below is based on denominated skills and talents of a certain child and aimed at an outlet of his imaginative and exploratory abilities. Typically, in the process of playing a game, children apply their factual knowledge, which is easier to understand and remember. That’s why it is notable that they use objects or all sorts of materials to assist them in realizing the surrounding environment in which they live and find out more about the characteristics and properties of things they are playing with. In this case, according to the rules of the game called â€Å"Bricks Mix† children are dealing with material objects such as sand, small bricks, or sticks. Preferably, the teachers should conduct the activity outdoors, i. e. in the park, on the beach, in the forest, in the backyard, etc. It would be helpful both for the picture of health of small kids and their better perception of the situation and conditions due to fresh air and active physical exercises. Also, if possible, the supervisor has to conduct the children at first stages giving the instructions and explaining the details of the activity. The latter is divided into two levels. First, using dry or wet sand, bricks of various sizes, short and long sticks, small stones, and water children build houses, roads, and fortresses. After a certain period of time when children get better acquainted with the situation and find themselves comfortable in the given atmosphere it would be a good idea to upgrade the game. Hence, each child individually should be given a card or oral request with a certain task, for instance, to build a house with 3 or 5 towers, to build a sand road with 6 bricks on each side, to make a castle with 4 towers and 4 flags on them, etc. While sifting, pouring, and filling empty containers with sand children get the idea of measurement and may observe visually the phenomenon when 2 small equal bowls of sand make 1 large container. Or if they put together two triangular stones or bricks they will have a rectangle or a square. Here, the major mathematical concepts are applied as the child deals with various shapes and sizes. Also, new terms should be used by the teacher, preferably associated with a certain topic or area of knowledge. The second stage of the game is characterized with using waste materials. It means that after building roads, castles, and houses children are provided with a large amount of things left from which they can make other objects like cars, stores, trains, buses, etc. This part of the game develops the ability to properly organize the process of managing the situation or business using less energy and expenses during the shortest possible period of time. It remains essential for the teacher to follow the work of the children without interfering into the process. It must be a positive sign for him/her when the child starts judging, analyzing, and comparing the results of his on-going work with others. In such a way he demonstrates his/her ability to productively be involved in the activity and learns how to work in team and cooperate with the peers. In order to make the results of the game more effective and have the kids remember the procedure it would be useful to talk in details about the activity afterwards. The coordinator should encourage the children to share their experience and discuss all the aspects of the game even if it causes some disagreements and controversy. Obviously, the debate would take place due to different methods, manners, and techniques applied during the game. The teacher should keep in mind that each and every child should be listened to and heard, which is more important. Some kids would try to prove that their idea or theory is the most optimal for this kind of activity. For example, they would argue that the train should consist of a number of short wagons instead of several longer ones as the first will be better while turning right or left. If the perspective of the child is valid the teacher should unpersuasively explain it to other children. Otherwise, they would undoubtedly feel that the mentioned above child is a favorite student of the teacher. It may not be accepted as a distinct gradation of the children may appear. However, in spite of numerous ideas expressed, it is significant to reach a compromise so no child is left unsatisfied. The reason the game â€Å"Bricks Mix† was developed lies in that this activity comprises several essential aspects of human mind as memory, reflection, counting, etc. It is useful for six-year-old children as well as nine-year-olds because different levels of difficulty may be applied. For example, younger kids may be given easy assignments simply connected with small numbers, while the older ones may be allowed to include other objects into the game. As the latter is rather flexible the teacher can coordinate the game and establish new rules according to abilities, inclinations, and skills of children. The activity is best possible while being outside the classroom not only during school time, but also while sharing weekend with parents, grandparents, friends, etc. BIBLIOGRAPHY 1. Lester, P.

Essay on American History 1865 - PresentEssay Writing Service

Essay on American History 1865 - PresentEssay Writing Service Essay on American History 1865 Present Essay on American History 1865 PresentThe period of Reconstruction (1865-1877) can be characterized by considerable changes in political and social life of the country. Blanche K. Bruce’s Speech in the Senate (March 31 1876) highlights the significant role of the state and political rights of all people (Bruce, 1876). The major goals of Radical Reconstruction were not feasible ones. Â  The three major issues to solve by the government were dealing with the states after their joining to the Union; treating southern whites, and dealing with the freed slaves. Lincoln’s plan for reconstruction was opposed by Congress (Bowles, 2011). Â  It is hardly possible to transform a society drastically by government action, especially if the Radical Republicans failed to agree with Johnson’s plan and developed their own Reconstruction plan. Actually, the might attempts to do so prove to be counterproductive. The process of reconstruction and its consequences is demonstrated in the documentary Slavery by Another Name directed by Sam Pollard. The film challenges the assumption that slavery in the United States ended with Abraham Lincoln’s Emancipation Proclamation of 1863. The documentary shows the emergence of absolutely new forms of slavery after the Civil War, including the deceptive forms of forced labor in the South, involving thousands of black people, who were kept in perpetual bondage. The violence of slavery would continue until the WWII (Pollard, 2012).As a matter of fact, a more gradualist approach to extending rights to and establishing freedom for African Americans could have been more successful. However, the costs and dangers of such an approach could have been dramatic. The struggle for freedom has always been a complex task. African Americans would have been more successful in achieving their goals, if they had had enough support and power to protest against slavery and discrimination.
