The Science of Toxicology
The Science of Toxicology Introduction to Toxicology: The science of Toxicology consists of the study of biology, chemistry, and medicine, that is concerned with study of harmful; effects of chemicals on living organisms. It also studies the harmful effects of the chemical, biological and the physical agents in biological systems that establish the extent of damage in living organisms. The relationship between the given dose and its effects on the exposed organism is of very high significance in toxicology. Variables that influence chemical toxicity, includes the given dosage, the probable route of exposure, species, age, sex and environment. A toxicologist is a scientist or medical personal who specializes in the study and observation of symptoms, function and mechanism, treatments and detection of venoms and toxins; especially in case of poisoning. To work as toxicologist one should get a degree in toxicology or a related field like biochemistry and the life sciences. The main branches of toxicology are: Forensic toxicology: It is the use of toxicology and other disciplines such as pharmacology, chemistry such as analytical chemistry and clinical chemistry to aid medical or legal investigation of death due to poisoning, and drug use. The chief concern for forensic toxicology is not always the legal outcome of the toxicological investigation or the technology used, but rather the obtaining and interpreting of the evidence and results. A toxicological analysis now can be done to various kinds of samples. A forensic toxicologist must minutely consider the context of an investigation, particularly any physical symptoms that are recorded, and any evidences collected at scene of the crime that helps in narrowing the search, such as any available chemicals powders and/or trace residue. Armed with this information and samples with which to work, the toxic substances that are present there, its concentrations, the probable chemicals effects on the person, all of these information are determined by the forensic toxicologist. In vitro toxicity: It is the scientific analysis of the effects of toxic chemical substances on cell cultured bacteria or mammalian cells. These methods are used primarily to identify dangerous chemicals, to verify the lack of certain toxic properties in the early stages of development of potentially useful new substances like therapeutic drugs, agro chemicals, food colours and additives and other useful substances. In vitro assays for xenobiotic toxicity are carefully considered by major government organizatios (e.g. EPA, NTP, FDA), to better assess human risks. There are major activities in using in vitro systems to advance understanding of toxicant activities, and the use of human cells, tissues and organs to define human-specific toxic effects. Environmental toxicology: It is a multidisciplinary field of science concerned with study of the harmful effects of various chemical agents, biological agents and physical agents on living organisms. it is a sub discipline of environmental toxicology that is concerned with studying the harmful effects of toxicants, at the general population and ecosystem levels. Medical toxicology: It is a medical subfield focusing on the diagnosis of health problems, their management and prevention of adverse health effects such as poisoning and other complications from medications, occupational toxicants, toxicants in the environment, and/or various other biological agents. Medical toxicologists personal are involved in the assessment and treatment for poisoning, the harmful drug reaction, overdoses and substance abuse. Medical toxicology practitioners are physicians, whose primary specialization is generally in emergency medicine, occupational medicine or pediatrics. Ecotoxicology: It is the study of the effects of toxic chemicals on the biological organisms, at the population, community and at the ecosystem levels. Study of Ecotoxicology is a multidisciplinary field, which combines toxicology and ecology. The ultimate aim of this approach is to be able to predict the effects of pollution so that efficient and effective action to prevent or remediate any adverse effect can be identified. In the ecosystems that are already affected by pollution, Eco toxicological studies can inform as to the best method for action to restore the ecosystem efficiently and effectively. Ecotoxicology differs from science of environmental toxicology in that it combines the effects of stressors across all the levels of biological organizations i.e. from the molecular to whole communities and ecosystems, whereas science of environmental toxicology focuses upon the effects at level of the individual and below. Entomotoxicology: It is the analysis of toxins in arthropods that feed on carrion. Using arthropods in corpse or at crime scene, investigators can correctly determine whether toxins or poisons were present in a body at the exact time of death. This technique is a major advancement in forensics. Before, such determinations were impossible in the case of the severely decomposed bodies, which were devoid of intoxicated tissue and body fluids. Ongoing researches into the effects of toxins on arthropod and their development has also allowed better estimations of the postmortem intervals. Forensic entomology is the application and also the study of insects and other arthropod biology to criminal matters. It also involves application of study of arthropods, such as insects, the arachnids, the centipedes, and millipedes, crustaceans to the criminal or legal proceedings. It is mainly associated with death investigations; however, it may also be used to detect drugs, poisons and determine the location of an incident, and also find the presence and time of when the wounds were caused. Forensic entomology can thus be further broken under three subparts: urban, stored-product and lastly medico-legal/medico-criminal entomology. Toxinology: It is the specialized field of science that deals mainly with the animals, plants, and microbial toxins. It has been defined as the scientific discipline dealing with microbial toxins, plant toxins, and animal venoms. This involves more than just the chemistry and mode of action of toxins. It deals with the working of venom, the poison-producing organisms, also the structure and functions of the venom glands, use of the venom or poison and also the ecological role of these compounds. Toxinology has also been further defined as the science of toxic substances produced by or stored in living organisms, their properties, and their biological importance for the organisms involved. Clinical toxinology: Within toxinology there is also a subgroup, i.e. clinical toxinologists, who studies the medical effects in humans, exposure to the toxins, also in animal venoms or in plant poisons. This includes problems such as venom from snakebite, currently considered to affect more than 2.5 million patients each year, with over more than 100,000 deaths. Clinical toxinology does not have specialist status yet within the field of medicinal study, unlike other fields such as surgery and radiology. However, training courses in clinical toxinology exists. Sample Preparation: Sample preparation is often the first step in an analysis; the result of this step can affect the rest of the analytical process. To get accurate results, a sample should be representative, it should be reproducible, homogenous, and must be suitable for column injection or other assay. The main steps in sample preparation are: Sample Identification Sample reagent and standard pipetting Sample extraction Output to analyzer format Preparative Steps: Removal of Soluble Protein ââ¬â precipitation ââ¬â filtration Extraction ââ¬â single step liquid-liquid extraction ââ¬â Multiple step liquid-liquid extraction (ââ¬Å"back-extractionâ⬠) ââ¬â solid phase extraction Chemical Modification ââ¬â derivatization for increase in volatility of sample ââ¬â chemical hydrolysis of glucuronide enzyme Concentration ââ¬â evaporation Cell lysis or tissue homogenation Sample Characterization: There are many chromatographic assays (GC, GC/MS, HPLC, TLC, LC/MS/MS, ), that are used for characterization and toxicological analysis of sample. To understand them, it is best to break them down into their modular components/steps: Sample preparation Separation (the actual chromatography) Detection (UV/Vis spectrometry, Fluorescence spectrometry, Mass spectrometry). Chromatographic Components: Sample ââ¬Å"loadingâ⬠The ââ¬Å"mobile phaseâ⬠during separation. The ââ¬Å"stationary phaseâ⬠during separation. Separation of individual molecules in the sample components is always based on their relative affinity for the mobile phase versus the stationary phases. Because some of the molecules have higher affinity for the stationary phase, they will pass through column slower than the others and, therefore, will be separated. Separation of the different Molecules by Chromatography: After the injection, all molecules start out overlapping. Due to the varying relative affinity for the stationary phase versus the mobile phases, individual molecules thus begin to separate As the different molecules then elute off of the column, they are then detected as resolved ââ¬Å"peaksâ⬠. Relative Retention Times: During the separation, the absolute rates/times for movement of the molecules are not always reproducible. For example, the columns can get dirty, thus decreasing the amount of stationary phase that is available for the interaction with molecules. This can be compared to shortening the length of the column. However, it affect the rate and all molecules in the same way. Therefore, their relative rates/times are highly reproducible. The ââ¬Å"relative retention timeâ⬠(RRT) is defined as the detection time for a individual peak divided by the detection time for a known internal standard. RRTs are characteristic and reproducible identifiers of individual molecules. Quantification of Drug Concentrations: Peak ââ¬Å"areaâ⬠generally correlates with the amount of drug that is loaded onto a column and on the original drug concentration. But, there can be sample-to-sample variations due to the extraction efficiency, the loading volumes, or the detection efficiency, etc. Again, the internal standard is utilized to correct for variations.ââ¬âSimilar to the relative retention time, relative peak intensity is defined and related to drug concentration. Unlike the relative retention time, the given variation in the peak area is not always similar for all the molecules. Thus, the internal standard is chosen to be chemically similar to the analyte of interest to best correct for variations. However, adequate similarity is not easy to predict or establish. Protocol for Quantification of Analyte Concentration Based Upon a Calibration Curve: A known quantity of an internal standard is first added to every sample (including controls and calibrators) before any other preparative step. All samples are then prepared through the identical preparative steps, separated by a chromatographic method and quantitatively detected. The relative peak intensities are measured for a series of calibrators with a fixed amount of internal standard and varying amounts of a known analyte. These relative peak intensities are fit to an equation, generally linear, to define a calibration curve. The relative peak intensities of unknown samples are then calculated and then related to the calibration curve to quantify the concentration of the analyte(drug) in the original clinical sample. Some Characterization Techniques: Affinity Chromatography: Affinity chromatography is used for separating biochemical mixtures based on the highly specific interaction between conjugates such as that between antigens and antibodies, enzymes and substrates, or receptors and ligands. Principle: Here, the stationary phase used is typically a gel matrix, often of agarose. Generally, we use an undefined heterogeneous group of molecules in solution, like, for example, growth medium or blood serum. The molecule of interest will be having a well-defined property, and can be put to use during the affinity purification process. This process can thus be seen as a process of entrapment, with target molecule getting entrapped on solid or stationary phase and/ or medium. The molecules of mobile phase component will not become trapped as they do not possess this property. The stationary phase is then removed from the mixture, washed and target molecule released from entrapment in process known as elution. The most common use of affinity chromatography is for the purification of recombinant proteins. Affinity chromatography has use in number of applications, including purification from nucleic acid, and purification from blood and also protein purification from cell free extracts. Thin-layer chromatography (TLC): It is a chromatography technique used to separate non-volatile and stable mixtures. Thin-layer chromatography analysis is performed on sheet of various mediums, such as glass, plastic, or aluminum foil, they are then coated with a thin layer of adsorbent material, like silica gel, cellulose and also aluminum oxide. This layer is known as the stationary phase. After the sample is applied on the plate, a solvent or solvent mixture (known as the mobile phase) is drawn up the plate via capillary action. Because different analytes have different rate of ascension on the TLC plate, separation is achieved. It can monitor the progress of a reaction, or determine the purity of substances and/or identify the compounds present in a given mixture. Some examples are: analyzing the fatty acids, detection of pesticides ,herbicides and/or insecticides in food and water, analyzing ceramides, analyzing the dye composition of fibers in forensic toxicology, or identification of medicinal plants and their constituents and assaying the radiochemical purity of radiopharmaceuticals. A number of enhancements to the original method have been made, to increase the resolution achieved with TLC, to make the different steps automatic and to allow more accurate quantitative analysis. This is called HPTLC, or high-performance TLC. Summary of Major Learning Points: Modular nature of chromatograpy. ââ¬â Assays are divided into three steps: sample preparation, sample component separation and analyte detection. ââ¬â The separation steps consist of sample loading, preparing a mobile phase and a stationary phase. Importance of an internal standard for ââ¬â Calculating the relative retention times for component separation. ââ¬â Calculation of the relative peak areas and the generation of a calibration curve for the quantification of drug concentrations in the original clinical sample. Analytical specificity provided by ââ¬â Sample preparation techniques ââ¬â Separation during chromatography (RRT) ââ¬â Method chosen for detection

Alcoholism Problem Essay
Alcoholism is a chronic problem that includes difficulty in controlling drinking, having to drink consistently to get physical independence, being preoccupied with alcohol, and continually using alcohol regardless of problems it causes (Brick, 2004). Alcohol should not be legal in U.S. because it is impacts negatively on health, family, community and on a personââ¬â¢s education. Alcohol drinking is like taking a drug. It is a form of drug addiction and drug abuse. Alcoholism is a worldwide problem that affects many people. Drinking alcohol has negative short and long term effects. Alcoholism has been associated with adverse effects on health, family, community, and education (Marshall, 2000). However, the effects on a person depends on particular factors such as how often and how much alcohol is taken, a personââ¬â¢s age, gender, when a person begun drinking and how long they have been drinking, their health, and family history (Begleiter & Kissin, 1996). It is in this regard t hat alcohol should not be legal in the United States. Alcohol is addictive, and people become addicts end up spending a lot of money on alcohol. It means that when they spend all the money they have on alcohol, they forget their families, and are not able to support the community in anyway. Some resort to stealing to sustain their drinking habit. Alcohol addicts sometimes engage in robbery acts to get the money for drinks. Community becomes at risk of destruction with excessive alcohol consumption allowed. When many people engage in excessive consumption of alcohol, education becomes at risk. People drop out of school, and illiteracy level increase in the community. In addition, the progress and development of any community depends on the health of its people. Therefore, when alcohol puts the health of its members at risk, community suffers in the long run. Alcohol affects both female and male differently. Men who consume alcohol, daily have an increased risk of health risks. Such men can experience cancer and heart disease in the long-term andà low energy to sexual difficulties in the short-term (Brick, 2004). Men are more likely to suffer from liver cirrhosis, and have higher chances of being diagnosed with high blood pressure. Nearly 26.6% of deaths among men of be tween 16 and 24 years old can be attributed to alcohol consumption. Men tend to be more dependent of alcohol (Marshall, 2000). Drinking too much alcohol damages a personââ¬â¢s body organs such as liver, brain, stomach, heart, and intestines. Brain is adversely affected because the brain cells die leading to loss of memory, learning difficulties, brain disorders, confusion, and problems with attention (Blane & Leonard, 1999). Liver is highly affected because of the great possibility of developing cancer in the liver, throat and mouth. The stomach may also acquire ulcers. Long-term drinking has also been linked to stroke and heart failure. The nervous system can also experience damage leading to behavioral and physical problems (Dasgupta, 2011). These problems affect health, family, community, and education in the long-term because of expenses associated with alcohol consumption, and possible treatment measures. Alcohol poses many effects on the body such as fertility. It reduces levels of testosterone. As a result, it could decline sperm quantity and quality, and lead to loss of libido. Alcohol is toxic to the testicles, and affects hormones. It could hamper production of sperms, hinder them from developing properly, and slow their movement towards the egg. Alcohol can also limit the liver from metabolizing vitamin A properly. It also depresses the nervous system, and could result in difficulty in getting and keeping erection (Peters, 2008). Many young adults do not realize that alcohol has a fattening effect. Alcohol can reduce the amount of fat that the body burns for energy. The human body makes several attempts to eliminate alcohol very fast as it cannot remain in the body for storage. The process takes priority over nutrient absorption and burning of fat. In the long-term, there could be a serious damage in the appearance. Other effects include loss of hair in the body, breast enlargement, and withering of testicles (Dasgupta, 2011). Alcohol has also been associated with worsening of skin disorders such as rosacae. Rosacae skin disorder is responsible for expansion of blood vessels in the face making it redder. Heavy drinking can cause the appearance of pus spots and red bumps. It has also been linked to inflammation, pain and swelling in the joints. The effect is common among men of between 30 and 60 years oldà (Hannigan, Spear, Spear & Goodlett, 1999). As mentioned earlier, heavy drinking increases the chances of heart disease, liver damage, bone disease, cancer, anxiety and depression, and type II diabetes. Heavy consumption of alcohol also caused inflammation on the pancreas and irritates stomach. These effects indirectly affect family, community and education (Peters, 2008). Women are not safe from alcohol either. The body of women takes much time to process alcohol compared to men. Women feel more effects of alcohol than men even when they drink the same amount. The fertility of women is at risk with heavy consumption of alcohol. Women are high risk of acquiring breast cancer, and adverse impacts of the menopause. Women are advised in several studies to avoid alcohol when trying to have a baby. Alcohol disrupts menstrual cycle in women, and limits their chances of conceiving. These are bad effects on the body, and not good for family and community in general. Therefore, alcohol should not be legal in the United States (Hannigan, Spear, Spear & Goodlett, 1999). While drinking less alcohol may make one look good, heavy consumption causes bad skin, tired eyes, and weight gain for both f emale and male. It also interferes with peopleââ¬â¢s sleep. Heavy consumers of alcohol often wake up and feel like they have not had enough rest. Alcohol dehydrates the body and skin. It deprives the skin of certain vital nutrients and vitamins. Hence, it is not good for health. Alcohol is also responsible for much divorce among couples due to fights in the family, and lack of finances for family upkeep (Dasgupta, 2011). Alcohol is depressant. It means that alcohol calms people down, and slows down some body organs. With only 0.05% level of blood-alcohol, a person begins getting dulled judgment, and his or her inhibitions get released. They then become clumsy and start having slurred speech with only a 0.10% blood-alcohol level. At 0.30% level of blood-alcohol, one nearly becomes unconscious. Any addition after that becomes extremely dangerous since at 0.45%, one can get into a coma. Brain shuts down from 0.70% and stop controlling the heart, breathing, and one may end up dead. Other short-term effects include blurred vision, blackouts and insomnia. These can lead to injuries, accidents, and even death. Drinking alcohol also causes hangover in the next morning, which is associated with nausea, headaches, heartburn, fatigue, thirst, and dizziness. There are many side effects of alcohol (Peters, 2008).Conclusion In conclusion, consumption of alcohol should be reconsidered in U.S becauseà of its adverse effects on health, family, community, and education. Alcohol should only be taken when necessary. The side effects are adverse and continue to destroy people across the world. Therefore, alcohol should not be legal in the United States because it is impacts negatively on health, family, community and on a personââ¬â¢s education. References Begleiter, H., & Kissin, B.

Essay on Forests and Coniferous Trees - 624 Words
Forests are basically a complex mix of living things such as animals, trees, shrubs, plants, fungi, and many more, as they cover about 40% of Canadaââ¬â¢s land. As forests play an important role in this complex community, as we need those to survive to build shelter, food for animals, and most important is fresh air. There are many different types of forests that include different types of trees such as coniferous, and deciduous, such as boreal forests, mixed forests, deciduous forests, grasslands, cordilleran vegetation, west coast forests, and many more. Coniferous trees are a type of tree that is also called a needle-leaved tree, which drops its needles during the fall; this special tree grows in a triangular shape, making itâ⬠¦show more contentâ⬠¦The good thing about this method is that its very useful for the loggers as they replant the trees, as in the future as the trees reach maturity and grows up uniformly in size and species. The bad thing about this method i s that if replanting fails, exposed soil may erode, and could damage the land. Loggers from the northern forests of pine, spruce, fir, aspen, and poplar are mostly cut in this manner. Some people think of clear-cutting as another method to destroy animals habitat. The next harvesting method is selective cutting, as the loggers only cut down mature trees of the desired size, age, and species, as for it is the least disruptive to the forest and to the animals. This method is the most expensive due to the care and time its used to cut down, as for the loggers cannot replant these trees again due to the space for a new uniformly forest, also it takes the longest. Trees that loggers cut down are usually hardwoods, such as sugar maple, are cut in this manner.

Types Of Therapies For Cancer Treatment Essay - 1558 Words
INTRODUCTION There are many different types of therapies for cancer treatment. Chemotherapy is the most common and following that is immunotherapy. A recent method has been discovered that is a targeted therapy. The recent discovery of targeted therapies has offered a wealth of improvements in the field of oncology. Targeted therapy is the most recent type of cancer treatment that uses drugs to attack solely cancer cells while trying to minimize the damage to normal cells. Targeted therapies attack the programming inside cells, what sets them apart from healthy normal cells. A recent targeted therapy of Poly (ADP-ribose) polymerases (PARPs) have been revealed to provide an alternative therapy for cancers that involve mutations in the genes: BRCA1 and BRCA2. These two genes are involved in repair of double stranded break (DSB). When either gene is mutated, the change can lead to errors in DNA repair that can cause cancer. According to the American Cancer Society, Poly(ADP-ribose) polymerases (PAR Ps) are enzymes that have been recently recognized as critical regulators of cell survival and cell death. Drugs that inhibit PARP-1 help fight cancers caused by mutations in BRCA1 and BRCA2. MECHANISM OF ACTION A research group in France discovered that flooding BRCA gene deficient cells with DSBs leads to cell death, and to do this they increased the number of SSBs thereby blocking the enzyme Poly (ADP-ribose) polymerase. Blocking this enzyme using various drugs is what isShow MoreRelatedCommon Treatment Options For Esophageal Cancer1524 Words à |à 7 Pagesmost common type of cancers around the world is esophageal cancer.

The Effects of Rap Music on Children Free Essays
Xavier Miranda Professor John Mammen English 1301 23 June 2012 The Effects of Rap Music on Children ââ¬Å"There is no danger of developing eyestrain from looking on the bright side of things. â⬠This quote fits perfectly with this topic. Too many people look at the negativities in music, Rap music to be specific. We will write a custom essay sample on The Effects of Rap Music on Children or any similar topic only for you Order Now Rap music can have negative effects on those who listen to it, but just as easily and equally have a positive and beneficial outcome. Yes, many rappers use vulgar derogative terms to describe women and may influence its listeners to break the law or things of the like; but it can also open our eyes, we can learn new things from it and it can influence us to be better people and do things, good things, with our lives. Now Rap isnââ¬â¢t anything new itââ¬â¢s been around since about the 1970ââ¬â¢s and been influencing those who listen to it for about 40 years now (ââ¬Å"Rapâ⬠). When people hear the term ââ¬Å"rap musicâ⬠their initial thought will be ââ¬Å"thatââ¬â¢s badâ⬠or ââ¬Å"thatââ¬â¢s demeaning to womenâ⬠which in a sense is true. For example the song ââ¬Å"Walk this wayâ⬠performed by Aerosmith and Run D. M. C. is about how a young high school student is lead through his first sexual experience by a debauched cheerleader. In a better known song ââ¬Å"Make it Rainâ⬠by Fat Joe he says ââ¬Å"Owwwww mamiââ¬â¢s body is banging, man/ she got it, man/ she does it all She gets it popping with no handsâ⬠And then thereââ¬â¢s the song almost everybody knows by Jay-Z. ââ¬Å"99 problemsâ⬠, where he refers to women as ââ¬Å"bitchesâ⬠. Songs like these make women seem like tools and expendable creatures, and may influence children that listen to this type of rap to treat women as such, ââ¬Å"but many of them were influenced as teenagers by gangster rap. Perhaps I should start using words like, niggers, hoes and slut-bitches since I would only be reflecting my societyââ¬â¢s musicâ⬠(Leary). But the best example, to make this point clear, is the music video ââ¬Å"Every girlâ⬠by ââ¬Å"Young Moneyâ⬠. In the video there are females dressed promiscuously throughout and the lyricist admits to wishing he could have sexual intercourse with every girl in the world. There many other songs that contain this type of disrespect towards the female sex, which gives a more credible argument to those who donââ¬â¢t like rap. Another point people may make against Rap music is the fact that many Rappers Rap and live very violently. Eminem is at the top of my list when it comes to being violent. Thereââ¬â¢s the song ââ¬Å"Who knew? â⬠in which he defends himself by saying: ââ¬Å"I never knew I, knew Iââ¬â¢d effect this kid/ I never knew Iââ¬â¢d, get him to slit his wrist/ I never knew Iââ¬â¢d, get him to hit this bitchâ⬠Although the song in and of itself is a bit ironic, Eminem acknowledges the fact that now he knows he can influence his listeners with his music. And in ââ¬Å"Love the Way you Lieâ⬠in which he says the following verse ââ¬Å"If she ever tries to fucking leave again/ Imââ¬â¢a tie her to the bed and set this house on fire. â⬠we see again the violence, and the music video for said song is of a couple who constantly fight and by the end of the song the couples house is up in flames. ââ¬Å"One study found that young subjects who watched violent rap videos were more accepting of violent actionsâ⬠¦Ã¢â¬ (Copley) and these lyrics that we very well hear over the radio and in our everyday lives promote breaking or disregarding the law, and many people still stop and wonder why the world is so violent. But like stated at the beginning of this paper there is a bright side to this moon. Before writing this paper laziness overcame me and I began to procrastinate and started listening to music and then the song ââ¬Å"Airplanes Part 2â⬠by B. o. b. feat. Eminem came on. Towards the end of the song Eminem says the words ââ¬Å"Pretend he procrastinated had no motivation/ Pretend he just made excuses that were so paper thin they could blow away with the windâ⬠which is what I was doing and it ââ¬Å"turned me onâ⬠and opened my eyes. As the song finishes Eminem continues to rap in third person about himself and how if it wasnââ¬â¢t for this one moment in his life that he had not chased his dream he wouldnââ¬â¢t be who he wanted to be. I then proceeded to get up and write this paper. So this song had an effect, a positive one on me. And it can have similar effects on others who listen to it. The language most rappers use is profanity, but a handful of rappers use uncommon words to express themselves, which can lead to one finding out the definition of the word and later possibly using them in school work. For example Eminem uses the word ââ¬Å"antidisestablishmentarianismâ⬠which is a political position in the Anglican Church that chooses to withdraw support from certain churches. And needless to say I used it in a world history paper. Thereââ¬â¢s also some songs by the rapper Immortal Technique who uses biblical metaphors in his music like in the song ââ¬Å"Point of no Returnâ⬠he asks us to open our eyes and actually see whatââ¬â¢s going on around us because the end of the world is near. Music like everything else has a good side and a bad side. Most people ignore the good and disregard Rap music as a whole. As expressed in this paper, yes it can have negative effects and influence children to do bad things but it can also influence them in a good way and even give them certain tools to use in the future.

Structure and Sticky Costs Accounting Research MyAssignmenthelp.com
Question: Discuss about the Structure and Sticky Costs Accounting Research. Answer: Introduction: Analysis and classification of cost involves the grouping of the overall cost into different logical groups based on a suitable approach. Classification of cost to Ocha Limited is crucial for controlling the cost and the purpose of decision-making. Cost can be classified into mixed, variable and fixed. The variable costs are those that varied with the amount of production or activity (Duan, Jing Lu, 2014). For example, the organic tea, spices and chemical products used by Ocha Limited for producing tea-flavoured ice cream, lollipop will increase with the increase in production. The fixed costs are those costs that do not change with the change in production level. For example, the cost incurred by Ocha Limited for the sales force and marketing team staff will not change with the change in production level. On the other hand, the mixed cost involves the elements of fixed as well as the variable costs. The utility bill that has to be paid for the production of various products of the company is recognised under the mixed cost. The cost for mixing process will be higher if more items put into the the mixing process (Persello et al., 2014). Understanding the behaviour of cost assists the management in various ways. For instance, Mr. Tomohiro can prepare the budget to forecast the costs and the measure the profits and then compare the actual amount with the budgeted one. Understanding the costs types that he is is incurring for his business will assist him to develop the proper mix for and the product volume that shall be manufactured to generate high level of profits for the company (Patil, Sherekar, 2013). This method is known as Cost-Volume-Profit analysis. Further the information of classification of cost will help Mr. Tomohiro for the calculating how many items he will have to produce for the break-even and cover the costs. Further, it is crucial to differentiate the costs into indirect and direct while making decisions regarding whether to purchase or make a specific product. Direct costs can be attributed to the production of a product, particular department or project. On the other hand, the costs those are expensed by the company but cannot be identified to the production of a particular item. For instance, the salary paid to the managerial staffs cannot be charged against one particular item. Understanding the behaviour of cost assist in calculating the overall cost of a product or project at projected volume; therefore, while making decisions regarding the cost, classification of cost plays an important role (Lo, Lin Wang, 2014). Usage of costing technique With the given scenario of Mr. Tomohiro for his company Ocha Limited, activity based costing (ABC) will be suitable for their business as they deal with various products for which they have to use various raw materials and various other overheads are involved in the process of the items like ice cream and lollipop (Balakrishnan, Labro Soderstrom, 2014). ABC system is the accounting system that recognizes the activities that an organization performs and then allocates the indirect costs to the products. The indirect costs like salaries to office staffs and management staffs are sometime tough to allocate to a particular product. ABC analysis is business term that is used to define the categorization technique for the management of material. This method is also known as the selective inventory control. The policy control under the ABC analysis provides accurate records and tight control on the items that are classified as A and good records and less control on the items that are classified as B. ABC system uses various cost drivers while allocating the overheads to the products. The multi-objective approach is also also implemented to offer better description for the trade-offs involved under the cost driver selection process. The cost driver under the ABC system led to the alteration in the cost of the activities. Cost driver is the factor that causes change in the activity cost. ABC systems focus on the attention of the management on the reasonable costs of the asset. It presupposes that the consumption of the resources leads to costs and the products incur the costs through the activities that are required for designing, marketing, invoicing and deliveries. The ABC costing system is beneficial in the following ways: Accurate cost of the product ABC assist in reliable and accurate determination of cost through focussing on the effect and cause relationship in the cost system. It identifies that it is the activities that leads to incurring of costs. In the circumstances of advanced manufacturing technology where the support functions and the overheads that constitute the large share for the total costs, the ABC offers more realistic costs for the product. Information regarding the behaviour of cost ABC recognizes the actual nature of the cost and assists in reducing the cost of the identified activities that are not attributed to the product value. With the ABC approach managers will be able to control the fixed overheads costs through exercise of more control on the activities that will fix the overhead cost. Recognition of overhead cost through ABC systems the overhead costs like manufacturing processes, customer related overheads, marketing overheads and allocation of overheads in appropriate manner (Kaplan Atkinson, 2015). Management of cost ABC offers rate of cost drivers and information related to the transaction volumes that are very crucial to the management for managing the costs and for the purpose of responsibility centres appraisal. The rate of cost driver can be advantageously used for the designing of new products or improve the existing products. Usefulness of ABC systems to Ocha Limited ABC system can offer better information system related to the costs nd assist the management to manage the business effectively and get better perceptive of the companys competitive advantages, weaknesses and strengths. It is obvious that Mr. Tomohiro, CEO of Ocha Limited will search for better costing system like ABC if they experience increase of lost sales due to the incorrect pricing that may results from the inaccurate costing of data. The ABC system is more effective with the firms dealing with various products, for instance, as Och Limited is dealing with various products like ready-to-drink beverages, tea flavour chillers, tea flavoured ice cream and lollipops. Moreover, though the sales level of Ocha limited has been increased between 2011 and 2016, they face huge competition from domestic as well as international competitors. The competitors offer faster delivery and lower prices for shelf space that cannot be offered by Ocha Limited at these moments. Therefore, through app lication of ABC, the CEO can have an idea for selling of which product will increase the profits and in which area the costs can be reduced to maximise the profits. Further, production of their products includes various overheads related to mixing process, sales mix and marketing mix. Therefore, through ABC, the overheads can be allocated on suitable manner to increase the profitability (Kaplan Anderson, 2013). Reference Balakrishnan, R., Labro, E., Soderstrom, N. S. (2014).
