Research Type - Essay Example Grounded theory is based on symbolic interactionism; wherein behavior develops through mingling and association with others in a process composed of negotiation and renegotiation (Morse and Field, 1996). It opposes the notion of average behavior and static reaction to symbols. Phenomenology studies behavior in the context of the individual’s experience (Morse and Field, 1996). Compared with grounded theory, phenomenological research supposes that meanings and behaviors are more internally controlled rather than a result of outside influence. Both methods require the generation of huge amounts of data because of the individualistic (phenomenology) and interaction-based (grounded theory) approach that it takes and both are essential to Nursing research because a patient’s reaction to a health care practice is influenced by both internal and external factors. Managing and organizing qualitative data for analysis is needed so as to make a coherent and relevant research. One way of handling large volumes of data is by categorizing each paper or resource and coding them so as to make it easier to find a particular resource when needed. Qualitative research analysis software (i.e. Nvivo) can also be used to index and sort massive amounts of information for quicker access. The use of online data bases can also be harnessed because these data bases are already organized and streamlined so analysis will be more efficient. (Polit and Beck,

Product or Service Design Research Paper Example | Topics and Well Written Essays - 750 words

Product or Service Design - Research Paper Example However, I shall be using the example of two very famous products and services around us. Firstly, I shall be describing the iPhone. This smart gadget, manufactured by Apple Inc, is more than just a phone and has revolutionized the communication and entertainment world around us. Secondly, I shall describe about a famous service that most people are addicted to. This is Facebook, the social networking website that has become one of the most popular websites of all times with millions of members from around the world. Competitive advantage refers to the advantages a product or a service enjoys over its competitors. In the context of iPhones, the product has a great competitive edge on its competitors. Firstly, when the product was launched, the iPods (another entertainment product by Apple Inc) had already captured the market. Hence, when Apple combined all those features into a phone, the product itself developed a competitive edge and became unique. Moreover, Apple provided the option to the users to install applications of their own choice. This option was never provided before in any phone, hence this also made the iPhone a unique product. Besides this, the sleek design and the touch interface also made apple acquire a competitive edge in the market. iPhone faced its biggest competition with well established brands in the communication market such as Motorolla and Nokia. Both these companies have launched their products in competition to the iPhone introducing almost the same features. Facebook, in order to get a competitive advantage, targeted the service only for college students initially. They allowed college students within a network to interact with each other. This created their demand amongst the social networking websites. Besides, Facebook also allowed users to use applications of their choice. When Facebook entered the social networking market, it faced its greatest competition from Myspace and Orkut. Both these websites had

Consultation topic paper - Essay Example s a phenomenon in which one or more industrial/managerial experts give their valuable and well thought opinion/advice to a client who seeks to improve performance or expand operations. Per se, a company that has recently incurred a big loss in business may turn toward some consultancy firm for getting some advice on maximizing profits or fill up the loopholes. However, different types of consultancy services are needed for the different types of organizations, individuals, and industries because everyone has a unique need. Yet, experts have managed to analyze the process of consultation in a generalized way. Roughly, consultation process is divided into six phases. These are: pre-entry (preliminary formalities and introduction); entry (exploring the problem, contracting, etc.); information gathering (data collection, problem confirmation, etc.); implementation (intervention selection, planning, etc.); evaluation and termination (Kurpius et al 1993; International Labour Organization 2 002; Ray 2011). The proposed draft addresses human resource or HR related issues, where training and interaction are the main foci. Scope of consultation in this context is around the nature and extent of the proposed training program. A necessity of consultation is likely to arise for the following reasons: Another requirement is to expand the target population of the team building program. Focusing just on the staffs of the specified non-profit organization may not be enough. Inducting corporate level managers and peers may help in fostering more professional attitude. Potential problems associated with each phase of consultation may affect the proposed team building program adversely. Selecting the right consultancy group or company is the most difficult task. Clash of opinions and collision of personalities may hamper both the consultation process and training program. Entry phase: The most crucial part of this phase is contracting. While contracting, the managers must be aware

Sociology & Scientific Depends Essay Example for Free

Sociology Scientific Depends Essay Sociologists have been divided on the issue of whether or not sociology is a science for as long as anyone remembers. It is a very controversial topic in sociology, due to the number of conflicting views about what it is to be scientific and according to the definitions of what is scientific, whether sociology can be categorised as a science. Durkheim and Compte, positivists believed that sociological studies should be based on the same logic and methods as natural science; they stated that this would create a positive science society and would allow us to discover laws of human behaviour, similar to the way scientists discovered the laws of gravity. Positivists believe that human behaviour, like that of a plant is influenced by external factors, that society shapes us and therefore that these factors can be isolated, controlled and measured. Durkheim believed that he had done just this when he had studied suicide, isolated the factor of being isolated as the cause of suicide. see more:when did sociology begin Popper was a famous philosopher of science, and he agreed with some of the positivists theories, claiming that indeed sociology could be a science. He said that natural sciences are scientific because they use the hypothetico-deductive approach, and look at evidence which may disprove their theory, as well as enforce it, he then went on to say that if sociologist could look at conflicting, as well as supporting evidence when trying to prove their theories, then indeed sociology could be considered scientific. Popper disagrees that human behaviour is only a product of outside stimuli, and so he is not a positivist, he simply agrees that sociology can be classed as scientific but in order to do so, studies must be conducted so that a hypothesis can be enforced or falsified. Popper argued that Marxism wasnt a scientific approach, because when its theory of a revolution failed but come true, they simply pushed its coming further into the future, instead of admitting the original hypothesis was untrue, therefore they prevented any possibility that the original theory had been false because they simply adapted it. Realists also believe that sociology is scientific, and claim that there is not much difference between sociological studies and natural science investigations. They held this view because like natural science investigations, sociology tries to explain the causes of behaviour in terms of underlying causes, which are not visible in everyday life. Sayer focussed on the fact that in all areas of science there were open and closed systems, for example in some situations, a lab can be used where variables can be controlled, but also in areas such as meteorology, experiments cannot always be fully controlled, he argued that sociology faced the same problem, studying issues which were relevant but complex, like meteorologists, sociologists had to deal with the fact that there may be other influences, but this does not mean that the studies they do are not scientific. Both study hidden causes of things relevant to their field, in ways that can be seen as scientific. The realist definition of science is Being scientific involves explaining behaviour in terms of underlying structures, mechanisms and processes. They believe that natural scientists and sociologists do, therefore sociology should be classed as a science.

A Proposal for a Law to Monitor Cloning Essay -- Argumentative Persuas

  Ã‚   The purpose of this essay is to propose a policy for monitoring and legislating cloning so that it can be used appropriately for science and medical research and benefits. This report will explain the needs for monitoring cloning, my plan for monitoring cloning, the many benefits that the world will gain from monitoring cloning, and how we can implement my plan. The Cloning Controversy Public opinion toward cloning is often negative. A Time /CNN poll taken a few days after Ian Wilmut's announcement regarding the cloning of a sheep found that 93% of Americans felt cloning was bad, and 66% opposed animal cloning (Masci 2). Many religious groups have taken a definite stand on the cloning issue. The Catholic Church has been a strong force against human cloning. It declared itself opposed to human cloning in 1987 (Peterson F1). The church had many reasons to be opposed to cloning, but some specific points were strong arguments for their side. The Pontifical Academy on Life felt human cloning would not result in identical souls because God created souls (Johnson 5). The Vatican panel also felt strongly against cloning. Human cloning, it said, "represents a grave attack on the dignity of conception and on the right to an unrepeatable, unpredetermined set of genes" (Johnson 4). Protestant churches have views on the cloning issue, too. Mr. Per Anderson, a leading figure in biomedical ethics for the Evangelical Lutheran Church of America and teacher of religion at Concordia College in Moorhead, Minnesota, said that the cloning issue:    has a certain kind of power over us. We associate this with divine power: changing the very structures of nature. It ties into our deep anxieties about the malevolent side to modern sci... ... we each do our part to work with our government officials, the cloning controversy can be eliminated and monitoring can become a strong reality.    Works Cited Bognanno, Frank E., and Joseph Jilka.

Exploring Traumatic Brain Injury in Children Essay -- Medicine

Traumatic brain injury (TBI) is one of the leading public health concerns today. The Center for Disease and Control (2010) reported that 1.7 million individuals sustain TBI each year). Moreover, TBI accounts to a third (30.5%) of all injury related deaths in the United States. Those who are most likely to sustain TBI are children (0-4 years), older adolescents (15-19 years) and older adults (65+ years) (CDC, 2010). This analysis will examine the prevalence, diagnosis, treatments, and prognosis of traumatic brain injuries in children. Brain injuries can be classified into mild, moderate, and severe categories. The most commonly used assessment for classifying TBI severity is by using the Glasgow Coma Scale (GCS). This scale assesses individual’s level of consciousness based on verbal, motor, and eye responses to stimuli. Researchers Kung et al (2010) analyzed the components of Glasgow coma scale (GCS) from 27,625 TBI cases in Taiwan. The correlation between the survival rate and certain eye (E), motor (M) and verbal (V) score combinations for GCS (scores of 6, 11, 12, ) were found to be statistically significant. The findings indicate that the three fundamental elements comprising the Glasgow coma scale (E, M, & V) separately and in some combinations are predictive of the survival of TBI patients. The researchers assert that this observation is clinically useful when a complete GCS score cannot be obtained when evaluating TBI patients. Confirmative neuroimaging scans plays a pivotal role in TBI diagnosis, prognosis, and deciding what treatments to give. CT is the preferred method of assessment on admission to determine structural damage and to detect (developing) intracranial hematomas (Maas, Stocchetti, Bullock, 2008). .. ..., Injury, Volume 42, Issue 9, September 2011, Pages 940-944, ISSN 0020-1383, 10.1016/j.injury.2010.09.019.

Calcium Carbonate and Ca2+ Ions

Experiment. EDTA Titration of Ca2+ in an unknown solution Experiment. EDTA Titration of Ca2+ in an unknown water sample Modified 9/2012 Objective: The most common multivalent metal ions in natural waters are Ca2+ and Mg2+. In this experiment, you will find the total concentration of calcium ions that can react with EDTA with the assumptions that EDTA reacts 1:1 with metal (Ca2+) ions. Equipment 250-mL Erlenmeyer flask (3) 50-mL Buret Ring-stand and hardware Desiccator 400-mL Beaker 500-mL Vol. flask 250-mL Vol. flask 1. 0-mL Vol Pipette 100-mL Grad cylinder Hot plate Safety and Waste DisposalChemicals Buffer (pH 10): Add 142 mL of 28 wt % aqueous NH3 to 17. 5 g of NH4Cl and dilute to 250 mL with water. Eriochrome black T indicator: Dissolve 0. 2 g of the solid indicator in 15 mL of triethanolamine plus 5 mL of absolute ethanol. 50 wt % NaOH: Dissolve 100 g of NaOH in 100 g of H2O in a 250-mL plastic bottle. Store tightly capped. When you remove solution with a pipet, try not to distu rb the solid Na2CO3 precipitate. Discussion: Hard water is due to metal ions (minerals) that are dissolved in the ground water. These minerals include Ca2+, Mg2+, Fe3+, SO42-, and HCO3-.Generally hard water arises because rainwater moves through limestone, CaCO3 underground that occurs in our area to the aquifer. This is why we measure hardness in terms of CaCO3. The concentration of the Ca2+ ions is greater than the concentration of any other metal ion in our water. The determination of water hardness is routinely used to measure the quality of water that the general public uses. Originally, water hardness was defined as the measure of the capacity of the water to precipitate soap. Hard water is not a health hazard since the main chemical in hard water is calcium.People regularly take calcium supplements. In fact, hard water can be a source of necessary minerals (calcium and magnesium) that is necessary for good health. Indeed, the National Academy of Science go so far as stating t hat that consuming extremely hard water could be a major contributor of calcium and magnesium to the diet. The problem with hard water is that it cause soap scum, clog pipes and clog boilers. Soap scum is formed when the calcium ion binds with the soap. This causes an insoluble compound that precipitates to form the scum you see.Soap actually softens hard water by removing the Ca2+ ions from the water. When hard water is heated, CaCO3 precipitates out, which then clogs pipes and industrial boilers. This leads to malfunction or damage and is expensive to remove. There are two types of water hardness, temporary and permanent. Temporary hardness is due to the bicarbonate ion, HCO3-, being present in the water. This type of hardness can be removed by boiling the water to expel the CO2, as indicated by the following equation: HCO3- (aq) ? H2O (l) + CO2 (g). Because bicarbonate can be removed it is classified as temporary hardness.Permanent hardness is due to the presence of the ions Ca2+ , Mg+2, Fe3+ and SO4-2. Because boiling cannot eliminate this type of hardness, the water is said to be permanently hard. The table below shows the degree of hardness of the water in terms of its calcium carbonate concentration in ppm and grains. Hardness rating Soft Medium Hard Hard Very Hard Concentration of Calcium Carbonate (mg/L or ppm) 0 < 75 75 to < 150 150 to < 300 300 and greater Concentration of Calcium Carbonate (grains/US gallon) 0 to < 5. 2 5. 2 to < 10. 5 10. 5 to < 21 21 and greaterPermanent hardness is usually determined by titrating it with a standard solution of ethylenediamminetetraacetic acid, EDTA. The EDTA is a complexing, or chelating agent used to capture the metal ions. This causes water to soften, but the metal ions however, are not removed from the water. EDTA simply binds the metal ions so that the ions do not precipitate to form soap scum. EDTA is a versatile chelating agent. A chelating agent is a substance whose molecules can form several bonds to a si ngle metal ion. Chelating agents are multidentate ligands.A ligand is a substance that binds with a metal ion to form a complex ion. Multi-dentate ligands are many clawed, holding onto the metal ion to form a very stable complex. EDTA can form four or six bonds with a metal ion. It is frequently used in soaps and detergents because it forms complexes with calcium and magnesium ions. The ions in hard water are bound to the EDTA and cannot interfere with the cleaning action of the soap or detergent. EDTA is also used in foods. Certain enzymes are responsible for food spoilage. EDTA is used to remove metal ions from these enzymes.It is used to promote color retention in dried bananas, beans, chick peas, canned clams, pecan pie filling, frozen potatoes and canned shrimp. It is used to improve flavor retention in canned carbonated beverages, beer, salad dressings, mayonnaise, margarine, and sauces. It inhibits rancidity in salad dressings, mayonnaise, sauces and salad spreads. In this la b you will be asked to determine the total permanent hardness. EDTA grabs all the metal ions in the water, not just the Ca2+ ions. This gives us a value that is not truly the concentration of Ca2+ ions.This causes an experimental error of about 1%, which is acceptable due to the â€Å"fuzzy† endpoints in this type of titration. Erio-T indicator or Eriochrome Black-T indicator is used in this titration. When it is chelated or acidifies, it produces a Pink-Red solution. When it is not chelated and under basic conditions it is Blue. The three pictures show the end point in this titration. There is a 1-drop difference of 0. 01 M EDTA between the first and second pictures and between the second and third pictures. Two or three seconds were allowed for colors in the second and third pictures to develop after adding the additional drop.In each case the solution was thoroughly mixed. This color change from wine red to violet to blue is due to the compact nature of the complex. Experi ment. EDTA Titration of Ca2+ in an unknown solution PROCEDURE Modified 9/2012 1. Dry Na2H2EDTA. 2H2O (FM 372. 24) at 80 ° C for 1 h and cool in the desiccator. Accurately weigh out ~ 0. 6 g and dissolve it with heating in 400 mL of water in a beaker. Cool to room temperature pour into a 500-mL volumetric flask. , mix and dilute to the mark. 2. You should practice finding the end point several times by adding a little tap water in a clean beaker and titrating with EDTA.Save a solution at the end point to use as a color comparison for other titrations. 3. Pipet a 1-mL sample of unknown into a 250-mL flask and fill to the mark with deionized water. Mix thoroughly. From this 250-mL stock solution draw 4, 50mL aliquot samples and place each aliquot in 250mL Erlenmeyer flasks. To each sample, add 3 mL of pH 10 buffer and 6 drops of Eriochrome black T indicator. To the first 50-ml solution, titrate with EDTA from a 50-mL buret and note when the color changes from wine red to blue. 4. Rep eat the titration with the next three samples to find an accurate value of the total Ca2+ concentration.Perform a blank titration with 50 mL of distilled water and subtract the value of the blank from each result. 5. Upon completion of the experiment, discard all solution in a chemical waste bottle and wash out the glassware. Be sure to dry your buret in the upside down position.Calculations – Analysis: Analyte Ca2+The reaction of Ca2+ ions with H2EDTA2- takes place with a 1:1 stoichiometric ratio: Ca2+ + EDTA2- ?
