Air and Water Pollution essay - 4881 Words

INTRODUCTION OF AIR POLLUTION The chemical composition of the atmosphere today is so different as compared to the atmosphere that existed before the Industrial Revolution, 1760 – 1830. To define air pollution, we should first consider all those sources that release harmful chemicals into the atmosphere and alter its chemical composition. First of all, all anthropogenic (man-made) emissions are air pollutants. Next, is the natural emission which can be divided into biogenic and geogenic. Biogenic emissions result from the living world such as volatile organic compound emissions from forests and CH4 emissions from swamp. On the other hand, geogenic emissions are from the non-living world, such as volcanic emissions, sea-salt emissions, and†¦show more content†¦-automobiles are the largest sources of VOCs for the reaction -concentrations tend to peak in the afternoon, causing eye irritation and aggravation of respiratory diseases Lead (Pb) -Pb levels in the air has decreased considerably with gradual elimination of lead in gasoline worldwide -leaded gasoline combustion -combustion of solid waste, coal and oils -emissions from iron and steel production and lead smelters -tobacco smoke -affect blood and kidney -affect the nervous, immune, cardiovascular and reproductive systems The above table was constructed based on the information obtained from : Daly, A. and P.

Overprescribing Of Stimulants For ADHD Case Study - 969 Words

Overprescribing of Stimulants for ADHD The most extensively studied childhood neurobehavioral disorder is attention-deficit/hyperactivity disorder (ADHD). ADHD is a chronic condition that occurs in about 8% of children and youth (Harstad Levy, 2014). Stimulant medications (i.e. methylphenidate and amphetamine) are very effective in decreasing the core symptoms of ADHD (Harstad Levy, 2014). Due to the increasing rates of stimulant prescriptions, there is now controversy on whether overdiagnosis of ADHD in youth and consequent overprescribing of stimulant medications truly exist. Author’s Perspective and Personal Experience Regarding the Issue Before 1970, the ADHD diagnosis was rare for school-age children (1%) and relatively†¦show more content†¦How to Limit Overprescribing, Misuse, Abuse, and Diversion Being a pediatric operating room nurse, I often take care of patients who are diagnosed with ADHD and is undergoing medical and behavioral treatments for their disorder. In my ten years of nursing experience, I have not encountered a patient who has misused, abused, or diverted their stimulant prescription, or at least not that I know of or it is not noted in their charts. According to Harstad and Levy (2014), misuse and diversion (i.e. giving away, trading, or selling) of stimulant medications are more widespread problems than abuse or addiction. Although methylphenidate and amphetamine both have abuse potential, there is very little evidence that these medications are abused by the patient to whom they are prescribed for. Moreover, about 16-23% of school-aged children have reported that they have been approached to by another person to give, sell, or trade their prescription stimulant (Harstad Levy, 2014). Friends and family members are the most frequent source of diverted medica tions (Harstad Levy, 2014). To prevent overprescription of stimulants, pediatricians or other primary care providers should seek to accurately diagnose ADHD and treat symptoms appropriately byShow MoreRelatedAttention Deficit Hyperactivity Disorder ( Adhd )3421 Words   |  14 PagesIn the previous years, attention deficit hyperactivity disorder (ADHD) has become more widely accepted as a relatively common disorder in the United States. With that, 8.8% of children were diagnosed in 2011 compared to 7% in 2007 (Pomeroy, 2013). However, as the rise in diagnostics has increased, so has the level of controversy.

BecauseRead MoreUse Of Stimulants For The Treatment Of Attention Deficit Hyperactivity Disorder ( Adhd )1891 Words   |  8 Pages The question of the validity of the use of stimulants for the treatment of attention-deficit hyperactivity disorder (ADHD) is highly connected to the question of attempting to balance the effectiveness of the drugs and the dangers inherent in their use.

Ritalin, like Adderall, is a stimulant that produces virtually the same effects as amphetamines. Now, Americans consume approximately 90% of the world’s Ritalin. Certainly, there are children that seem to benefit from these drugs, but there’s clearly a profit motive that results in unnecessary prescriptions. Some studies estimate that as many as 1,000 ,000 American children are misdiagnosed for ADHD. ADHD drugs are popular with adolescents for all

Database - Data Warehouse and Data Mining

Question: Discuss about "Database, Data Warehouse and Data Mining". Answer: Introduction Data Mining is the process of analyzing and categorizing the data in a number of different categories. The data is studies from various angles and a correlation is formed. It is used in a number of financial, marketing, retailing and other industries to determine the relationship between internal factors such as price, cost, inputs and the external factors such as profits, losses, customer satisfactions and feedback. Data warehousing lets business leaders sift through subsets of data and examine interrelated components that can help drive business. Looking at sales data over several years can help improve product development or tailor seasonal offerings. Data warehousing can also be used to look at the statistics of business processes including how they relate to one another. For instance, business owners can compare shipping times in different facilities to look at which processes and teams work most efficiently. Data warehousing also involves storing huge amounts of data in ways th at are beneficial to different divisions within the company. Databases are the structured sets of data that are present in a computer. Big Data and business intelligence Internet is loaded with huge volumes of data every single day and to manage this data with perfection is a task in itself. The buzzword in the technological world is Big Data. It refers to the massive volume of data which includes both the structured as well as the unstructured data. Organizations are now adapting Big Data as a technology in order to manage the huge volumes of data which is otherwise not possible with the traditional software and techniques [1]. Business Intelligence on the other hand is the set of tools and guidelines which converts a set of data in to meaningful information for the purpose of business and data analytics [2]. Advantages of Big data in data warehousing and data mining The basic aim of business intelligence is to optimize the processes that are involved in handling the information and achieve best possible results with improved customer satisfaction. This is brought in to application with the aid of Big Data. Big Data helps in figuring out the target customers and users. Predictive models are created and the inferences are made. Companies gather the data sets from the social media accounts, browser logs and other sources to gain an insight in to the general trends, practices and demands [3]. Optimization of business processes is another expertise of Big Data. Analysis of performance of the employees, creation of reporting, online analytics and processing are done with the help of this amazing technology. Other advantages of Big Data include: Cost Savings Hadoop is a tool that is used to implement Big Data and the use of the same can result in storage of data at a much lesser cost as compared to other techniques. Companies are therefore making use of tools such as Hadoop for the purpose of data warehousing rather than spending their cost in the expansion of data warehouse for storage and locating the data. After the data is stored successfully with the help of Hadoop, it is moved to the regular database that is used by the organization in order to analyze the data. Versatile big data tools can also function as multiple tools at once, saving organizations on the cost of needing to purchase more tools for the same tasks. Competitive Advantage Big Data allows its users to access the data easily which was difficult or next t impossible to access earlier. With the aid of such a capability to access the data from a number of different sources such as social media accounts, search engines, media streams and several more, companies can predict the demand for a particular product and can also implement and design clear marketing strategies. With these advantages, businesses are able to gain an edge on their competitors and act more quickly and decisively when compared to what rival organizations do. Needless to say, a business that effectively utilizes big data analytics tools will be much better prepared for the future than one that doesnt understand how important those tools are [4] New Business Opportunities New business opportunities can easily be approached and deduced with the help of Big Data. Advertising and marketing are the two sectors that have largely benefitted with the help of these processes. Add-on services, new services and real-time services are provided to the customers on the basis of the analysis done through Big Data and the business expands with the help of the same. In addition to those benefits, big data analytics can pinpoint new or potential audiences that have yet to be tapped by the enterprise. Finding whole new customer segments can lead to tremendous new value. These are just a few of the actionable insights made possible by available big data analytics tools. Whether an organization is looking to boost sales and marketing results, uncover new revenue opportunities, improve customer service, optimize operational efficiency, reduce risk, improve security, or drive other business results, big data insights can help [8]. Newer Databases NoSQL is the database that performs the Big Data Analytics with extreme ease. It provides rich visualization for creation of reports and documents that support the analytics results. It allows the flexible mode of exploration that is on the basis of various parameters such as time, geographical locations, revenues, quantities and many more. Predictive analysis with powerful and advanced algorithms such as classification, regression and exploration is also possible with the help of NoSQL [5] NoSQL data is the fabric that connects the more than 200,000 APIs (a number that continues to rise) in the world, each of which speaks the language of JSON or XML [6] It is an advanced database that promises consistency along with the scalability and supreme performance in the document and data storage and indexing [7] Conclusions Data Warehousing and Data Mining are the processes that work on huge volumes of data and can be successfully executed with the aid of Big Data. Business Intelligence is the major application area of Big Data and several techniques and tools have been developed for the same. In the present era, use of non-SQL databases namely NoSQL has increased which includes various databases under it. Bibliography [1] Jon Bakke, M. (2014). 5 big data implementation mistakes to avoid.

Role and Functions of Law free essay sample

Law is vast and diverse, which makes it overwhelming and confusing. The main purpose of the law is to create order in society and business. Law can be defined as â€Å"the body of official rules and regulations, generally found in constitutions, legislation, judicial opinions, and the like, that is used to govern a society and to control the behavior of its members, so Law is a formal mechanism of social control† (Sixth Form Law, 2012, par. 4). The following will describe the function of law and what role it has in society and business in addition to looking at how law affects a specific industry. Because American law is so diverse, it is broken down into several categories. Those categories include; Criminal law versus Civil law, Substantive law versus Procedural law, and Public law versus Private law. Please note that these categories are broad, and they are not mutually exclusive. An act or transaction can be classified in more than one legal category (Melvin, 2011). We will write a custom essay sample on Role and Functions of Law or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page First, laws, primarily statutes, are considered to be criminal or civil. Criminal law protects society. It is between private parties and society. For example, if someone is brought up on murder charges they would be tried in a criminal court of law. Violations of criminal law could result in penalties of fines or imprisonment to violators if convicted of the crime and proven to have intentionally committed the crime. Civil law is between private parties. Civil laws are created to compensate parties who have experienced losses because of the other parties’ actions. Examples of civil law could be divorce and accidental injury cases. Next are the differences between Substantive law and Procedural law. Substantive law is a statutory law, which deals with the relationship between people or people and the state. Substantive law is used to define, regulate, and create people’s rights and obligations. They deal with the structure and the facts of the case to determine the type of crime and the severity. It also defines the rights and responsibility of the accused. For example, there are several degrees of murder, depending on the circumstances and the intent; there are different levels of punishment. On the other hand, Procedural law is a set of rules that govern the proceedings of criminal lawsuits and civil proceedings. It elaborates on the steps of how the case should proceed as well as assists in determining if the case requires a trial. These laws ensure fair practice and consistency in the due process (Diffen, n. d. ). Last is the summary of Public law and Private law. Public law governs the relationship between individuals and the government. It includes constitutional law, administrative law, and criminal law. Domestic violence is an example of Public law. Private law, also known as common law in some countries, governs the relationships between individuals. It includes civil law, labor law, commercial law, corporations law, and competition law. An example of Private law would be a contract for services. If someone renders a service according to the request of the client, but the client is not happy with the results and refuses to pay for this service. This agreement is legally binding and the rules of transaction are governed by the common law of contracts (Melvin, 2011). There is much to digest once reading about the categories of law and to think this is just skimming the surface. In addition to these categories the Congress is given power via the Commerce Clause to â€Å"regulate Commerce among the several states† (Melvin, 2011, p 32). If Congress chooses to regulate certain persons or products, the federal law is supreme to the state law that tries to regulate the same persons or products. In the case of Cipollone v. Liggett Group, the state law regulating advertising for tobacco products were preempted by the federal law (Melvin, 2011). It is important to know how state and federal laws can affect society and business. One industry, which is under constant scrutiny, is Appraising. Appraising has both state and federal laws to abide with, and they are constantly changing. Appraisers are required to obtain certain standards that are set forth in the Uniform Standards of Professional Appraisal Practice (USPAP), which is published by the Appraisal Standards Board of the Appraisal Foundation. If an appraiser fails to comply with these standards there could be punishment of fines, lawsuits, or loss of license. In conclusion, it is important to know the basic roles and functions of law in both society and business even though it is vast and diverse. Laws are needed to create balance and order within society and business, and they can be broken into broad categories to obtain the basic knowledge.
