Economics - Essay Example Economics as an existing discipline which relies on meticulous argument styles. Its objectives cover the formulation of theories that have more sound theoretical grounding and are simpler in the manner of explaining economic phenomena. Frequently the explanation starts with a plain framework which depicts the relationships of the variables . The complexities are locked away in the assumption of ceteris paribus or all equality of all other variables. An example is moneys quantity theory , which posits a positive assocoiation among the money supply and price level, ceteris paribus. The theory can be put to test by utilizing economic data, like the price index of GDP and a calculation of the supply of money; for example, bank deposits along with currency. Its quantitative methodologies facilitate the impact of opposing rationalizations and challenge to fine-tune for extraneous effects. Of late, the utilization of experiments on economics has been very progressive; thus making it compara ble to the natural sciences. Microeconomics examines the agents economic performance as well as firms and individuals, their connections through the given insufficiency, character markets and administration guideline. For a product there is a market specified, for instance a corn which is a factor of manufacture called bricklaying. Aggregating of the amount required by buyers and the number provided by sellers at each probable unit price is measured by the theory. It weaves these together to explain how an advertise may arrive at the equilibrium as to the amount or price that responds to the market change over the time. Demand-and-supply analysis is the general termed. Market structures such as domination and perfect competition is examined which is implied as a financial competence or behavior. The proceeds remains unchanged based on the analysis from the simplifying statement that behavior in the market it is the so

Construction suveyour to have done layout Essay Example | Topics and Well Written Essays - 500 words

Construction suveyour to have done layout - Essay Example This kind of surveying is known as an â€Å"as-built† survey and is one of the five major elements of construction surveying (Irvine & Maclennan 145). The other major elements include checking conditions prior to commencing a construction job for example, topography and existing infrastructure. The other aspect is to mark and create reference points followed by verification of the location of structures during construction. When the construction surveyor was designing the layout for a municipal street intersection in Murfreesboro area, he must have put all the factors into consideration. There was a wide range of factors that were taken into consideration, some were basic whereas others were quite complex in regards to the design and construction. First and foremost, he had to consider the type of road to be constructed. In addition, the roadway allowances. These factors determine the amount of space to be allocated for the project and the general parameters in road construction. The surveyor had to consider the safety aspect of constructing the road where it is located rather than somewhere else. This is because in road construction, the topography is a factor of the essence to determine the design of the road as well as, the flow of runoff (Irvine & Maclennan145). Another factor that may seem obvious is the availability of other infrastructure that is. the pre-existing infrastructure and the proximity to the road. Some things like electricity lines, water, and sewer lines may have affected substantially the surveyor’s decision to position the road as it is now in Murfreesboro. Simple as it may seem, things like the power lines affect profoundly the lighting of the road in that the proximity of the power lines do not determine the availability of the street lights. There are the less obvious considered factors and that still count in choosing the methodology of choosing the design. These include the likes of expected traffic on the road. The amount of

Fiscal Policy Assignment Example | Topics and Well Written Essays - 250 words

Fiscal Policy - Assignment Example The fiscal policy has been instituted to see the government earn more revenue which is to be used to reduce the government debt which has been rising over the years especially following the release of stimulus packages to revive the economy after the financial crisis began. The fiscal policy currently in place disfavours the rich as it would see them pay more taxes. The middle class are also disfavoured by the fact that they have to pay 2% higher payroll tax than they have previously been paying. If not for the easy monetary policy that the country has adopted, many sectors of the economy would have been grossly affected by the financial policy and the unemployment levels would remain high. Generally, the fiscal policy will benefit those to whom the government is indebted. The Taiwan Government on has adopted an expansionary fiscal policy for the last seven years (Liu, 2013; weebly.com 2014). The policy includes raising spending on defence each year by 7.8%. The policy is aimed at stimulating domestic demand (weebly.com 2014). This measure has been taken in response to volatile exports. The government intends to invest in infrastructure and hopes that the economic growth will be more impressive. The policy favours local businesses and the general population although the government’s level of debt will keep rising. Mutikani, L. (March 22, 2013).

Work sheet - Assignment Example lingering aftermath of the 2010 BP oil spill in the Gulf of Mexico, a contemporary technical innovation which provides a â€Å"new method to improve the efficiency of cleaning up oil spills, using magnets† (Hall, 2012), holds significant potential. This new method is the brainchild of Markus Zahn, a professor of electrical engineering at MIT, and the research team led by Shahriar Khushrushahi of MIT’s Department of Electrical Engineering and Computer Science. MIT had a breakthrough in January, and unveiled its new concept in September this year, posting it as a YouTube video. This innovation originated in Zahn’s concept that, if oil was magnetic, it could be easily separated from water using magnets. It works on the concept of magnetized fluids, or ferro-fluids. These are synthesized fluids, made up of 10 nanometer magnetic nanoparticles coated with a surfactant to stabilize it within a host liquid. They are typically water or oil based. The mixture of oil and water is collected in a restricted space. The oil is made magnetic by the addition of the magnetic nanoparticles. The magnetic oil is then separated from the water, using large magnets, giving clean water and magnetic oil. Using existing technology, the magnetic nanoparticles are removed from the oil, and the oil is recovered and recycled. (Zahn and Khushreshahi, in Hall, 2012). The concept is implemented through an arrangement of cylindrical magnets which are embedded vertically in a large tank. Globules of oil from the magnetic oil and water mixture rise above the water line and are scoope d up by large magnets. (Casey, 2012). The current methods of cleaning oil spills are of five types, each of which is attended by significant shortcomings. The first method just leaves the oil alone, letting it disperse by natural means. This has the possibility of polluting coastal regions and marine industries. The second method uses dispersants to break up the oil and accelerate its natural biodegradation. The

Identify the components and interfaces commonly present in J2EE Essay

Identify the components and interfaces commonly present in J2EE projects as they progress through the development and design of the distributed architecture - Essay Example In a distributed computing environment, J2EE uses a multi-tiered application model. There are the (1) the web-tier components that run on the J2EE server; (2) the business-tier components run on the J2EE server; the (3) client-tier components that run on the client machine and (4) the Enterprise information system or EIS-tier software which runs on the EIS server. A J2EE component may be defined as a self-contained functional software unit that is assembled into a J2EE application along with its related classes and files and which is able to communicate with other components using programming logic (java.sun.com). In a J2EE distributed enterprise application model therefore, the application logic is usually divided into components according to their function, and the various application components that make up a J2EE application are installed on different machines depending on the tier in the multi-tiered J2EE environment to which the application component belongs. I believe that the RUP or Rational Unified Process is the best approach for J2EE applications. This consists of the following phases: Requirements Analysis, Object Oriented Analysis, Architecture Specification, Object Design, Implementation, Validation, Assembly and Deployment, and Operation and Maintenance (Kurniawan, 2002). All in all, we see can that the main usage of the J2EE environment is to develop and deploy enterprise applications. The modern J2EE platform consists of a set of services, application programming interfaces and protocols that provide the functionality for developing multi-tiered, web-based applications in a distributed computing

Abalytical Toxicology Essay Example | Topics and Well Written Essays - 2000 words

Abalytical Toxicology - Essay Example This still remains a great challenge for analytical chemists and may rely on identification of different target compounds. In the case of precursor drug administration, the parent compounds are usually detectable only for a short time, before being fully metabolised or decomposed. For this reason parent compounds can rarely be used for differentiating. Specific metabolites are usually detectable for a much longer time. Their use as target compounds for differentiating has found little application however, since all metabolites are not extracted together with MA and AM and are additionally fully converted to AM or MA after a certain time post administration. Enantiomeric profiles for methamphetamine and/or amphetamine, metabolically formed from precursors have been described for some medicaments and have been used successfully for differentiating between illicit intake and intake of precursors. Thus a reliable method for the quantitative determination of AM/MA enantiomers is essential for differentiation (Kraemer and Mauer, 2002; Musshof, 2000). A great number of research efforts have focussed on the separation of AM/MA enantiomers particularly from urine or blood matrices. These have been extensively reviewed (e.g. Kraemer and Mauer, 1998; Musshof, 2000). The majority of the methods employed involved enantiomer separation by chromatography, either by HPLC or GC on chiral stationary phases,with or without prior derivatisation with achiral reagents, or by GC on achiral stationary phases, after derivatisation with chiral reagents to the corresponding diastereomers. Detection was commonly by MS to ensure high selectivity and sensitivity. In terms of sample treatment for analyte extraction and concentration, conventional liquid-liquid extraction protocols (Kraemer and Mauer, 1998), solid phase extraction (SPE) on cartridges (Peters et al., 2002) and solid-phase microextraction (SPME - Nagasawa et al., 1996) have been commonly applied. The proposed methods varied in terms of sensitivity, reliability, sample preparation times and analysis times and adaptability to high throughput format. The current trend in the determination of MA/AM enantiomers is towards the substitution of chiral GC/MS protocols by runs on achiral columns of MA/AM diastereomers. This is because MA/AM diastereomerisation has been shown in several cases to improve resolution, to shorten the retention times of analytes and to enhance the response of the detector, i.e. to improve sensitivity (Kraemer and Mauer, 1998; Peters et al., 2002). Furthermore achiral columns are commonly less expensive compared to chiral columns. Different chiral derivatisation reagents have been applied successfully in MA/AM diastereomerisation (Kraemer and Mauer, 1998; Musshof et al., 2002; Peters et al., 2002; Wang, 2005). Recent advances in the field involve a fast SPME-based approach, where absorption and derivatisation are accomplished in a single step by adding the derivatising chiral reagent directly into the urine sample matrix (Wang, 2005) and the application of automated headspace solid-phase dynamic extraction (SP DE) coupled with GC/MS, for the determination of amphetamines and synthetic designer drugs in hair samples (Musshof et al., 2002). The later technique is an innovative GC/MS approach to the enantiomeric determination of amphetamines and will be discussed further. Headspace SPDE constitutes an alternative extraction and concentration method for volatile and semi-volatile organic compounds contained in liquid or gaseous samples. Headspace SPDE is a further development of headspace SPME. In fact, SPDE was developed

Health Informatics and Emerging Technologies Research Paper

Health Informatics and Emerging Technologies - Research Paper Example Electronic Health Record (HER) is a form of a longitudinal computerized health record that comprises of digitalized health information about a population or individual patients (Smaltz, 2007). Statement The health data in electronic form is generated and stored in medical institutions with the help of microchips, smart cards, etc. Then, such records can be accessed or be shared across within several healthcare settings through a network connection of information systems. The data contained in such records are in summary form and may include; laboratory test results, billing information, medical history and other essential medical data. This advancement in technology in medical field has enabled competent health record keeping, streamlined work flow, quality management, and safety and evidence based decision with supporting documents. Effective maintenance of electronic health records is a key component for the efficient functioning of healthcare organizations. As these records contai ns very sensitive information and personal details about the patients, leakage of which could adversely affect the patients’ personal as well as the professional life and also the organization’s standing. However, there are certain disadvantages with this Health informatics based system particularly related to high cost involved in installing and implementing the system, legal issues, etc. Although, there are demerits, there are many more merits for this system, and this paper will discuss how those merits can aid in the optimal functioning of Healthcare organizations. In addition, even the demerits can be managed, if correct steps are taken. Reduced Health Care Costs Imaging is a major contributor towards the increase in health care costs. Irrespective of the medical insurance safeguards, spending on imaging makes a lot of people avoid accessing medical services. However, this problem can become a thing of the past if the health care providers adopt the electronic hea lth records system, as it is an effective way of averting the normal at the same time expensive duplicating imaging procedures. Apart from the cost factor, by going for electronic storing and transfer of imaging outputs will also increase the efficiency of the doctors in correct diagnosis. This was validated by a study conducted by Garrido et al. (2005) in Colorado and Northwest regions of Kaiser Permanente, a US integrated healthcare delivery system, using the population of 367, 795 members in the Colorado region and 449, 728 members in the Northwest region as the sample size. The results showed that after â€Å"more recent increases in general use of imaging inside and outside Kaiser Permanente†¦The chief of radiology in the Colorado region believed strongly that availability of electronic records to all carers improved interpretation of films.† (Garrido et al. 2005). Storage of physical records requires large amount of space which translate to expensive storage, costs which can be easily cut down with the usage of EHRs. In addition, physical medical records may be stored in different areas and therefore induces the cost of transporting them where they are required. Bringing them to a single location for usage by health care providers is not only time consuming but also costly. Some times such records might be needed in multiple locations at the same time whereby there must be faxing or transporting costs incurred. All these can be taken care of by using the EHRs.
