Air pollution in Mexico City As the vehicle population reached more than 700 million worldwide, numerous cities experiencing rapid industrialization started to suffer from air pollution (Walsh, 1999). The level of air pollution in any city is a global concern. The reason is that air can travel freely from place to place; consequently, the polluted air from one city can travel to another. The polluted air has numerous negative consequences for human health and also severely damages the ecosystem. Some of the cities reduced the air pollution level; however there are still some that are considered to be the most polluted cities in the world. One of them is Mexico City. According to Forbes, the Mexican capital is one of the five dirtiest cities of the world (Luck, 2008). The government and people have take measures in order to reduce the air pollution in Mexico City before it is too late. The government should practice legal regulations and favor the usage of hydrogen fuel instead of gas oline in order to reduce the air pollution level in Mexico City.

Essays on Discuss the origins and evolution of accounting. What are the challenges currently faced by the profession Essay Origins and Evolution of Accounting and Challenges it is Currently Facing Accounting is the process that is used to identify, record, measure, verify, interpret and evaluate financial data of an organization. Accounting techniques and principles were developed during the times of ancient Roman Empire. The development of trade through the ancient Roman Empire up to the Industrial revolution necessitated the development of accounting. The changing business environment and modernization have improved the mode of doing business bringing several challenges to the world of accounting. This paper primarily discusses the origin, evolution and challenges facing accounting. Accounting has been in existence since the first occurrence of civilization almost 5000 years ago. In Rome, by 12th Century B.C., there was an advent of increased trading and the Roman Empire, being the most developed society at that time, needed an organized system that would document the profits it earned from its trading (Pacioli, 2010, 3). Luca Pacioli believed to be the father of accounting developed the system of double entry in accounting. He originally provided a base for double entry in bookkeeping and helped traders and merchants on proper accounting and better business practice (Pacioli 5).The Industrial revolution brought about the emergence of the need to have a more pronounced cost accounting systems as businesses developed into large corporations with more than one capital providers (Pacioli 7). Luca Pacioli says, â€Å"If you are in business and you fail to know all about your money, it will go like flies; you will lose it† (Pacioli 7). In 1887 during the industrial revolution, the rising need for public accountants led to the transformation of accounting into a profession in both the United States and England. Accounting developed into several branches such as, the financial accounting, management accounting, auditing, among others (Mukherjee Hanif 112). Financial accounting is the periodic reporting of financial condition of a company while management accounting deals with external forces such as business processes, monitoring and general business evaluation (Mukherjee Hanif 117). Auditing involves the periodic examination and verification of company accounts. Accounting has not been left behind with the global modernization, the emergence of computerized accounting and software engineering has developed software such as SAGE, Quick books and Microsoft Excel, which has supplemented and rationalized the accounting systems a factor that has reduced costs and improved business operations (Mukherjee Hanif 114 ). Accounting has currently faced several challenges with one being finding jobs for the rising number of fresh graduates from accounting institutions. The adverse global recession of 2008-2009 led to several closures of several corporations a factor that has reduced the availability of accountants’ jobs. Health problems related to stress and high blood pressure has been reported within the profession as the increase in the level of workloads business (Schroeder 57). Integrity in reporting financial condition of corporations by accounting professionals has come out as another challenge. Uncouth accountants who broadcast wrong figures to influence investors to invest in their companies stocks have in some occasions misguided investors on the financial conditions of some corporations (Schroeder 65). This has caused adverse effects with some leading to a crash in stock market. In conclusion, accounting has undergone a tremendous evolution from a simple bookkeeping to a wider and significant factor in determining the course of business, monitoring and evaluating financial condition and forecasting of where to invest and not to invest.

Managing Overtime Worked in the Workplace Free Essays

string(153) " only alternative to this situation is to have employees already present complete their assignments and pitch in to help deliver the vacant assignments\." In the following report, I will be give illustrations and possible solutions for an overburdening problem that exists in the U.S. Postal service Operations throughout the country. We will write a custom essay sample on Managing Overtime Worked in the Workplace or any similar topic only for you Order Now Overtime is an age-old problem that has gone long overdue without someone or a group paying serious attention to correcting this problem. The United States Postal Service is a large organization with many facets of operations; I will be concentrating on what we call the Field Operation or Area Office. This is where the public comes into personal contact with the Postal Service either by way of the individual letter carrier (mailman) or the window clerk who assists with business transacted at the post office. Every community across America has a Post Office. We are one of the most visible employers in the world. The U.S. Postal Service employs approximately 750 thousand diverse people. Many different cultures and nationalities come together to combine as an efficient workforce that gets the job done. The pay is moderate, so it would be pretty difficult to become independently wealthy working for the Postal Service. But, there are some employees that believe if they work, as much overtime as possible, maybe they can become rich. Unfortunately, this poses a daily obstacle to overcome for most managers in the U.S. Postal Service. The U.S. Postal Service is a production driven outfit therefore; everything is based on production verses cost ratio. The average workday for a postal employee is eight hours. It does not take a genius to figure out that the longer it takes to do the job, the more money is made. So, the employee that desires more money would be motivated to take longer to complete his or her assigned task(s). Historically, the Postal Service has been plagued with managers that were not diligent in doing their jobs with regard to overtime management. Because of this clusters of employees became accustomed to a Carte Blanche style of working. Employees were in effect managing the overtime and work production. During my career as a letter carrier, I completed my assigned tasks within my eight-hour shift working overtime only when deemed necessary by my manger. When I became a manager, I expected everyone who worked for me to have the same work ethics that I had. If this was not case, I attempted to force them to work as hard as I did. I later found out that this was not a good management approach. In fact, this was the easiest way to harvest disgruntle employees. Here was my dilemma; I was the new young manager who expected an honest day†s work, for an honest day’s pay, paired with a staff that had been allowed to do whatever they wanted for the past ten years. The office of my first management assignment had 90 percent of the employees working an average of 10-16 hours of overtime per week. My performance as a manager as well as well as the production performance for our office was based on the amount of manpower hours used to deliver the total volume of mail. I will present information about the systems put in place that worked as a check and balance format. These systems enabled me to demonstrate to my employees that my requests were not unfair or unreasonable. I will discuss the areas that the employees were able to assist in helping to aleve the excessive use of overtime. I will also discuss in detail areas that contributed to the excessive use of overtime that did not involve my employees. With implementation of the new systems, my office has reduced its overtime to 14 percent.    While controlling overtime may seem as easy as just making an announcement â€Å"that no one is allowed to work overtime†; this is very far from true in the U.S. Postal Service area offices. There are many variables that come into play, the first of which is staffing. In order to do a good job; the office must be properly staffed. We have percentage breakdowns that factor in amounts of carrier routes; amounts of deliveries per zip code that derives to an employee complement. Each office has a number that satisfies their complement. If for any reason a particular office is operating under their complement that makes the task a more difficult. Any office can be fine one week and short the next, due to retirement, injuries, or details to name a few. If any of the aforementioned were to occur a manager could request replacement for these employees, whether they will be granted or not is another story. Then we have the day-in day-out mystery of who will call in on sick leave. Having any of these instances to take place in a given day can simply cripple an operation. If we take a carrier operation anywhere in the world that has 35 city carrier routes and 4 carriers call in sick on a Monday, that manager now has to scramble to get coverage for those four vacant routes. It is not like other organizations where your work can carry over by one day; the mail must be delivered daily without exception. This makes it difficult to get the work done in an eight–hour day for the remaining employees. The first thing the manager must do is to telephone four employees who would normally have the day off and ask them to come in and work their day off. Bare in mind that the U.S. Postal Service has something called an Overtime Desired List, a voluntary list of employees who wish to work overtime on assignments. When the manager telephones employees to come in on their day off, he must first call those on the Overtime Desired List. If the manager does not get four employees from the list, he may then exercise the option to call employees not on the Overtime Desired List. The only alternative to this situation is to have employees already present complete their assignments and pitch in to help deliver the vacant assignments. You read "Managing Overtime Worked in the Workplace" in category "Essay examples" The advantage of this situation is that it allows you to minimize your overtime usage for the day. If the manager was able to get four employees from the Overtime Desired List to come he has automatically used 32 hours of overtime for that day. By having employees already present work additional hours, you are able to use far less overtime for that day. This is an area I feel managers need to stress to their bosses so that all efforts are exhausted in hiring more employees for offices to operate under their complement. The earlier mentioned example could have been avoided had that office been properly staffed. A fully complemented office would have unassigned employees who would have been given those assignments for the day avoiding the need for overtime. In order to be a successful office you must be fully complemented. When I was finally able to get my office fully complemented my overtime was reduced by 10% – 30% as shown in the graph below. The U.S. Postal Service has another formula that we use to gauge an employee†s production. There is a standard based on demonstrated ability. We can not hold Carrier A to Carrier B†s standards. This formula is for sorting letters and flats (magazines, newspapers, etc.). The formula allows 1 hour to sort 2 feet of letter mail. This is 2 linear feet, 2 linear feet equals 454 pieces of letter mail or 230 pieces of flat mail. So in order to standardize an employee the manager must count out 2 feet of mail, letters or flats, and calculate the amount of time it takes the employee to sort this mail. The average carrier has no problem at all meeting this quota, but there are those who attempt to outsmart their managers. If the manager is not focused on them during the sorting period there are those carriers who have the tendency to leave their areas to socialize among their coworkers, or â€Å"slow sort† their mail. The longer it takes a carrier to sort his mail, the longer it takes that carrier to get out of the office on the street to deliver this mail, making this same carrier late in returning from his assignment guaranteeing this carrier overtime for the day. You multiply this by several carriers in one office daily and you come up with an unaccountable amount of overtime usage as a manager. This affects your production numbers for the office as a whole. This where a manager has to jump in and approach the individual carriers immediately. As a manager I that this has happen to, I have approached the individual and asked some very basic questions to make certain that there are no health or personal issues going on with the carrier affecting their productivity. If nothing out of the ordinary exists, I point out that they are not meeting their productivity quota and make certain suggestions to assist them in meeting their quota. There are those times when you are challenged as a manager to verify your findings. When those situations arise, I go out and measure, with the carrier present, the actual number of feet of mail for them to sort and time them sorting this mail. Once you demonstrate to your employees that you are only expecting from them what is minimally required, and that you will hold them accountable for just that you run into this type of problem less and less. Another major contributor to overtime usage is the actual mail flow itself. Most days this is not a problem, but when it is a problem it is usually a big problem. In Northern Virginia we have two mail distribution centers, one in Merrifield and one in Dulles. For the Falls Church Post Offices, we receive our mail from Merrifield. Each morning we receive 3 dispatches of mail from 6:00 a.m. to 8:30 a.m. When these dispatches are on time everything runs smoothly, but when these dispatches are late an office goes from running smoothly to being hectic. One of the main reasons for a delayed dispatch is the mechanical failure of a mail-processing machine in Merrifield. In preparing itself for the new millenium, the U.S. Postal Service Distribution Centers are equipped with high-tech automated mail processing machines that do the job of ten employees sorting mail. In the event of a mechanical failure, one of our dispatches can be delayed by 1 – 2 hours. This 1 – 2 hour delay is passed along to my operation in 1 – 2 hours of down time for my carriers while they are waiting for their mail to deliver. That equals approximately 1 –2 hours of unforeseen overtime per employee that day. As demonstrated in the graph below this is a large usage of overtime for an entire office when calculated. The combination of mail volume and properly scheduled mail dispatches is critical in minimizing overtime. In closing, I would suggest that as we approach a new millenium the U.S. Postal Service would be better served by doing away with some of the older ways of thinking. The Overtime Desired List should be dismantled. This forces managers to go outside of the employees already present for work as a first solution to a vacant assignment list. To me this encourages overtime usage. I would also suggest for offices receiving mail dispatches late at least 3 times a week to move their scheduled time for mail receipt back and bring their carriers in a little later to accommodate for the dispatch schedules. For example if an office has consistently been receiving their dispatches an hour late, instead of having the carriers report to work at 6:30 a.m. they would move the carriers reporting times up to 7:30 a.m. instead eliminating that hour of downtime per person that they are losing.

The Effects Of Drugs Essay Research Paper free essay sample

The Effects Of Drugs Essay, Research Paper Introduction Many different drugs have different effects on the organic structure. This paper focuses on the effects caused by three widely used drugs opium, cocaine, and hemp. They have many common effects between them. Some features of the effects of those drugs are those of stimulations and others are those of sedatives. We will depict the chemical effects of each drug on the organic structure. Opium Opium is a drug produced from the capsules of the opium poppy. When fresh from the works it is a icky light brown mass ( # 8221 ; Opium, # 8221 ; Microsoft? Encarta? Online Encyclopedia 2000 ) . After it is allowed to dry out it hardens and darkens. Its chemical expression consists of 17 C atoms, 19 H atoms, 3 O atoms, and 1 N atom ( Barbara Hodgson, 1999, p 15 ) . Opium has an extended history. It was foremost used about 3400 B. C. In the early 1800? s British opium runners illicitly smuggled the drug into China. In making this they made tremendous net incomes and hooked many Chinese citizens on the drug. This illegal trade caused a war, suitably titled the? Opium War. ? Finally when the Chinese began migrating out into the universe they spread opium usage. Opium can be smoked, eaten, rummy or injected. Most commonly it was smoked. This was in portion because opium designed for smoke was the cheapest and easiest to obtain. Smokers took their wont really earnestly. They normally possessed a tobacco user? s kit, which included a lamp to illume the opium, a box to hive away it, one of a assortment of different pipes, excess bowls for the pipe, a sponge and bowl scraper to clean the pipe, and a pillow to rest their caputs on as they smoked ( Barbara Hodgson, pgs.1-46 ) . Most tobacco users did so in groups, usually in topographic points called? opium dens? . These lairs were located in metropoliss and many in Chinatowns. Chinatowns were countries within metropoliss where the Chinese migrated to, lived, and brought their dependences to. The nuts who ingest opium orally are nicknamed? opium feeders? ( Barbara Hodgson, p.3, 62 ) . This comestible opium is in the signifier of pills and it has a dreadfully acrimonious gustatory sensation. The signifier of opium that can be drunk is called tincture of opium, which is an opium-alcohol mixture. ( Barbara Hodgson, p 3 ) . With the innovation of the subcutaneous syringe during the American Civil War, injection presented another manner for nuts to acquire their hole. The opium derived functions that were introduced to the organic structure through a syringe were called morphia and heroine, both of which were highly habit-forming. There were commercial drugs that were introduced into the market which were suppos ed to assist nuts kick their opium wont. These drugs did non assist really good due to the fact that most of them contained either opium or some other habit-forming drug, hence hooking the nut. Other commercial merchandises that contained opium were cough sirups and babe comforting medical specialties. Of class, opium would do babes halt shouting but it had many negative side effects. Many kids grew up with malformations and mental deceleration. Opium was a really popular drug, but it caused much injury ( Barbara Hodgson, p1-7 ) . Opium? s short-run affects include sleepiness, dizziness, failing, euphory, dry oral cavity, urinary keeping, and irregularity. It is said that the most effectual manner to smoke opium is by lying on your side with your caput on the pillow mentioned in the tobacco user? s kit. Most people could non sit up and smoke opium because they became excessively giddy or tired to stay unsloped, or were to weak to keep up the pipe. Whenever people smoked opium they went to kip instantly afterwards. This was rather a sight at the opium dens, where there would be tonss of people passed out on the floor. They smoked merely for a few proceedingss of pleasance and anyplace from 1 to 3 hours of near-paralytic slumber. Opium gave a impermanent feeling of euphory to anyone who used it. This was the chief ground why the drug was in such high demand. It let people acquire off from the emphasis of their mundane lives. Opium besides caused its maltreater to desiccate. After smoking one would imbibe much H2 O and liquid to assist comfort their atrocious thirst. This desiccation leads to irregularity and urinary keeping, both of which tended to be rather painful ( http: //new.health-center.com/db/PageReq ) . Opium? s long-run affects include hallucinations, psychosis, and ictuss. If an opium nut consumed their drug over a long period of clip, they normally developed several harmful side effects. One of them was repeating hallucinations, which have been compared to the? trips? induced by the contemporary psychedelic drug LSD, besides known as? acid. ? During these hallucinations people see objects and people that are non truly at that place. These people and objects sometimes talk to them. For case, if an nut was holding hallucinations while eating, their nutrient might speak to them and state, ? Don? T eat me. ? Another long-run affect that relates closely to hallucination is psychosis. This is the status in which the user loses touch with world, their head is really disorganised, and their thought procedure is altered greatly. They are witting but do non hold much common sense ( hypertext transfer protocol: //new.health-center.com/db/PageReq ) . Psychosis is a type of altered consciousness. Seizures are another side consequence, happening after prolonged usage of opium. This is because the organic structure is rejecting the drug. As with any drug, opium overdosing is possible. The symptoms that indicate an overdose are marked by excess sleepiness and giddiness, utmost confusion, a possible coma, bradycardia ( abnormally decelerate pulse ) and down external respiration ( http: //new.health-center.com/db/PageReq ) . Some other drugs derived from opium include morphia, heroine, and codeine. Both morphia and heroine can be injected into the organic structure through the usage of acerate leafs. Morphine is normally given for hurting alleviation to people who have undergone surgery or who have serious hurts. Morphine acts in the encephalon to diminish the feeling of hurting and to cut down emotional response to trouble, as do most opiates. Since morphia is made from the same poppy flowers as opium it is extremely habit-forming. Morphine was used more in the yesteryear than it was now. It is on its manner out of the drug mistreating society ( hypertext transfer protocol: //www.healthcentral.com/mhc/top/002502.cfm ) . Heroine usage, on the other manus, is lifting in the drug community. Heroine? s effects are about indistinguishable to morphine? s because it is made from the same opium poppy and it is introduced to the organic structure in the same manner, through a acerate leaf. Codeine is another opiate that is turning rather popular today. It is introduced into the organic structure in the signifier of a pill. It is habit-forming but non about every bit habit-forming as the other opiates mentioned so far. It is used as a analgesic and cough suppressant ( hypertext transfer protocol: //www.healthcentral.com/mhc/top/002502.cfm ) . All of these opiates are rather harmful to the organic structure as are most illegal drugs. To kick their dependence, nuts must travel through many old ages of rehabilitation and normally through many returns. After traveling for some clip without their drug the nuts in rehabilitation undergo backdown. Opium backdown symptoms include anxiousness, depression, sickness, diarrhoea, or hurting ; symptoms vary with the type of drug. The overall uneasiness associated with backdown is due to the deficiency of drug content in the user? s system. After an nut is so used to being high and they come down, they can non manage a normal life with emphasis. Opiates are atrocious drugs and they have many hideous effects on the organic structure ( http: //new.health-center.com/db/PageReq ) . Cocaine Cocaine is a powerful stimulation with awful side effects on the organic structure. # 8220 ; It is a stimulating drug derived from the South American coca works, Erythroxylon coca # 8221 ; ( Weiss, Mirin, and Bartel, 1994, p.169 ) . The intranasal, inspiration and endovenous usage causes complications to critical variety meats in the organic structure and besides creates many complications such as the geting diseases and psychiatric jobs. One of the ways cocaine may be used is in the signifier of coca paste and cleft used thru smoking. ? Coca paste consists of a mixture of cocaine, kerosine, sulphuric acid, and Na carbonate? . The white or brown paste is allowed to be dry after being manufactured ; it is so placed at the terminal of a baccy or marihuana coffin nail, and inhaled profoundly? ( Weiss, Mirin, and Bartel, p.20 ) . Cocaine can besides be smoked in the cleft signifier and is made utilizing a process of responding chemicals. ? Crack is produced by uniting cocaine hydrochloride with Na hydrogen carbonate ( baking sodium carbonate ) . This mixture is heated until all the H2O has evaporated. The attendant merchandise is little white french friess, dwelling of the alkalic precipitate of cocaine? ( Weiss, Mirin, and Bartel, p.21 ) . Another signifier of cocaine is crystalline cocaine hydrochloride. This compound is chopped up finely by a razor blade to be used for snorting and/or for endovenous usage. # 8220 ; Cocaine is prepared for endovenous disposal by puting between one-tenth and one-fourth of a gm in a spoon and so adding H2O. This aqueous solution is so strained, after which it is drawn up into a syringe and injected into a vena. Euphoria occurs about instantly # 8221 ; ( Weiss, Mirin, and Bartel, p.23 ) . Cocaine is popularly used because it works as a vasoconstrictive. A vasoconstrictive is a substance that can compress blood vass to a specific country to where it was applied. ? ? . therefore blood vass in the country exposed to cocaine are reduced in size, and blood flow to that country is diminished? ( Weiss, Mirin, and Bartel, p.34 ) . Since cocaine restricts blood flow, foods and O are unable to flux decently to many variety meats, which restricts the cells in that country to go malnourished. When the blood flow is diminished, it causes the individual # 8217 ; s sympat hetic nervous system ( which controls the â€Å"fight or flight† response ) to be activated. Once the sympathetic nervous system is activated, a user enters in a province of euphory where the individual may experience more activated and qui vive. One of the variety meats that the vasoconstrictive effects is the bosom. When cocaine is taken through intranasal disposal, a high bosom rate and blood force per unit area may ensue. These jobs can take to cardiomyopathy, the status in which the bosom contracts abnormally. # 8220 ; Cardiomyopathy may be caused by a direct toxic consequence of cocaine on the bosom. Peoples who have cardiomyopathy are more susceptible to bosom onslaughts and to sudden cardiac decease # 8221 ; ( Weiss, Mirin, and Bartel, p.34 ) . The ground myocardiopathy may ensue is due to the sudden addition in bosom rate and blood force per unit area. Cocaine besides has effects on the respiratory system. An overdose of cocaine may ensue in respiratory apprehension. A individual can besides obtain other respiratory jobs if he or she smokes it, because of the reduced sum of transit of O to the blood. A syndrome called cleft lung may ensue. # 8220 ; Patients with this syndrome may see chest hurting, shortness of breath, or coughing up blood. Symptoms may get down about instantly after smoking cleft, or up to 48 hours after cleft was last used # 8221 ; ( Weiss, Mirin, and Bartel, p.35 ) . Out of all the variety meats in the human organic structure, cocaine produces the greatest effects on the encephalon. # 8220 ; Cocaine is a really powerful drug that deeply influences encephalon map # 8221 ; ( Weiss, Mirin, and Bartel, p.70 ) . The encephalon plants by directing electrical urges to every nervus cell in the organic structure. The encephalon uses neurotransmitters to transport electrical urges across the spreads that separate nerve cells.
