Industrial Effluents in the Water Pollution Essay Example

Industrial Effluents in the Water Pollution Paper Water pollution is caused by emission of domestic or urban sewage, agricultural waste, pollutants and industrial effluents into water bodies. Nowadays, its main source is the waste material discharged by industrial units. Waste materials like acids, alkaline, toxic metals, oil, grease, dyes, pesticides and even radioactive materials are poured into the water bodies by many industrial units. Some other important pollutants include polycarbonate phenyl (PC) compounds, lubricants and hot water discharged by power plants. The pollutants unloaded into the water bodies usually dissolve or remain suspended in water. Sometimes, they also accumulate on the bottom Of the water bodies. Another important pollutant, that can endanger marine life, is the oil spilled by oil tanks. As per the estimates of the United Nations, 1. 3 million barrels of oils are spilled annually into the Persian Gulf, and about 285 million gallons are spilled into the oceans every year. In the United States, the industries contribute to more than half of the total water pollution. The industrial effluents contain pollutants like asbestos, phosphates, mercury, lead, nitrates, sulfur, sulfuric acid, oil and many other poisonous materials. In many countries, industrial water is not treated adequately before discharging it into rivers or lakes. This is particularly true in the case of small-scale industries that do not have sufficient capital to invest in pollution control equipment. In many instances, the researches and studies carried out to determine the toxicity of these pollutants are focused on the individual effect of the toxic elements.

Besides, their toxicity is assessed with the help of tests carried out on bacteria, which also fails to take into account the accurate toxic effects on other organisms. These harmful pollutants are a major contributor to many grave diseases such as diarrhea, cholera, hepatitis, dysentery and salmonella. Besides, many of the pollutants are also carcinogenic I. E. They can cause cancer. Some pollutants like sodium can cause cardiovascular diseases, while mercury and lead cause nervous disorders. EDT is another toxic material which can cause hormonal changes. Excess fluoride in water may damage the spinal cord, while arsenic can cause significant damage to the liver and the nervous system. In addition to all these, organic compounds present in the polluted water facilitate the growth of algae and other weeds, which in turn use more oxygen dissolved in the water. This reduces the amount of oxygen dissolved in the water and the consequent shortage of oxygen for other aquatic life. In recent times, to control the menace Of water pollution, various legislations have been introduced by different countries. The legislations undertaken by he United States include Federal Water Pollution Control Act (1 972), the Marine Protection, Research, and Sanctuaries Act (1972) and the Safe Drinking Water Act (1974). Besides, Federal Insecticide, Fungicide, and Redirection Act was also amended in 1988. For the success of these legislations, cooperation of the citizens and industrial units is an important prerequisite. In addition to the enforcement and proper use of these rules and regulations, availability of efficient and cheaper pollution control techniques is also required to tackle the threat posed by water pollution.

Modern Architecture essays

Modern Architecture essays During the early twentieth century architecture took a new turn into the more modern way, with clean lines and a new influence of nature, which resulted in a new era of design as a whole. With this new way of thinking came a line of architects that would take architecture into a revolution, such as William Le Baron Jenney, Louis Sullivan and Frank Lloyd Wright. Their ideas would change the way of architecture and would have a lasting impression on architecture in the future along with how it was taught. The Industrial Revolution had so changed technology and design that old concepts no longer seemed right. Starting in 1840, leading artists, designers, and critics tried to develop new approaches to architecture. Modern architecture has its roots in a number of different origins. One of the persistent ideas in 20th-century architecture, however, is the belief of many, engineers as well as architects, that beauty could be seen in the clear expression of the structural properties of the new materials (Curtis 25). As iron, glass, and steel became available, building construction was no longer limited to stone and wood. One structure built for the Paris Worlds Fair of 1889 showed this exactly. The Eiffel Tower, by Gustave Alexandre Eiffel, which was seven-thousand tons of steel, was erected to soar nine-hundred eighty-four feet into the sky, as part of the centennial celebration of the French Revolution. Like this steel skeleton many other buildings would soon use the same type of way to build. High-rise buildings were made possible by the building of a steel cage, on which to hang the floors and walls. The basic skyscraper office building took form in Chicago by the 1890s and spread rapidly elsewhere. Involved were some exceptionally able architects, including members of the Chicago School. The Chicago School, an American architectural movement based in late 19th-century Chicago, was the ...

Critical event analysis - Essay Example From the resemblance alone, I could tell that the boy was their son. They looked around the room in a confused manner and then stared at my mentor and I. We both began to approach the young family. My mentor turned to the parents and began asking questions about why they were there. At that moment, a noisy group of people entered the emergency room and rushed towards us. The young couple did not answer my mentor’s questions, but turned to the group and began to converse loudly in a foreign tongue. My mentor tried to stop the cacophony but was unable to. The hospital’s security guards strode towards the noisy crowd and began to sternly signal for everybody to remain silent. The young couple which was now at the centre of the small crowd suddenly turned to their small boy who had been silently observing everything, and delicately began to remove his sleeve from his hand. My mentor suddenly reared back in shock and stopped their action by grabbing both of their hands. I cr aned my neck to see what had upset her and, to my shock, saw a number of purplish blisters across the boy’s arm which is a characteristic of an iron burn. ... At this point, the parents ran past the security guards and came towards us. I turned to them and began to question them about the incident. They could not speak clear English, and made signs of ironing while pointing at their boy. My mentor asked for the hospital worker who is from the same ethnic background as the boy to be located and brought to assist with communication efforts. What were the consequences of the actions taken for the patient and others involved? Once the worker reached the emergency room, he began to interpret what the boy’s parents were saying as I helped my mentor to apply an antibiotic ointment on the burn. My mentor knelt so as to be on the same level with the boy when asking questions. She asked simple open-ended questions which the boy could reply to with ease. She also used a soft tone of voice so that the child would not be further upset. Then she turned to the parents and indicated for the hospital worker to inform them that the boy would remain f or observation. She also asked for the workers to be informed that this was necessary so that further infection would be prevented, so that the parents would agree to leave the boy in the hospital. In reality, she wanted to ask more questions about the accident. Even though the child remained silent, nodding or shaking his head when questioned, his parents and seeming relatives were still talking in moderate tones outside the door. The revelation that the boy would be admitted brought some protests from a few people, but, in general, others were in agreement with this decision. Reflection How were others feeling, what were the other perceptions involved? I could see that my mentor was deeply disturbed by the

Childbirth - Thesis Example All in all many patients think that VBAC is safe after the age of 35, or when the foetus is big or that the pregnancy has progressed more than 40 weeks, yet it remains again to doubt as these facts themselves lower the chances of being able to deliver vaginally. But still patients having acquired this kind of data prefer VBAC and this stems from basically the intrinsic desire to be able to experience the natural process of birth and plus avoidance of the scar that the c section leaves behind and the post operative pain . All those who opted for VBAC knew that Information gathering was very important as it helped them to cope with the situation in a better manner and to understand the risks involved and eventually make a better judgment for themselves. The fact that a prior scar could open and it is very dangerous for both mother and baby put the patient's nerves at edge, for in such emotional status it was too worrisome for them to consider anything remotely dangerous for their babies, and did not want to take any risks. Patients having vertical uterine c sections avoided it totally .Those with multiple caesareans, single layer closures, uterine surgery, narrow pelvis, breech foetus, triplets, genital herpes also could not have VBAC. This varied a lot in women and mostly depended up... They had previously failed the normal process of vaginal birth. They did not want to experiment with the rare risk of the c section scar opening up during the vaginal delivery and fearing of which shrunk these patients from considering VBAC. The fact that a prior scar could open and it is very dangerous for both mother and baby put the patient's nerves at edge, for in such emotional status it was too worrisome for them to consider anything remotely dangerous for their babies, and did not want to take any risks. Most patients who had doubts about the hospital facility of handling emergency shrunk from the risk, and especially patients who's labour did not start on its own and cervix remained closed and firm. Patients having vertical uterine c sections avoided it totally .Those with multiple caesareans, single layer closures, uterine surgery, narrow pelvis, breech foetus, triplets, genital herpes also could not have VBAC. Anxiety of patients regarding Caesarean: Infection that could develop, in the incision.

Dominos Pizza UK & IRL plc Case Study Example | Topics and Well Written Essays - 2000 words

Dominos Pizza UK & IRL plc - Case Study Example The company focuses on selling only one product - pizza - and throughout the year, as it has been doing in the UK and Ireland in the last 20 years, minor improvements are made to get the product to the customer in the shortest possible time. In 2006, the company launched an 'out-the-door' campaign that cut the time from order taking to the start of the delivery down to 15 minutes. Thus, by combining the quality of the product with speed of service, Domino's was bale to increase its repeat orders, which is a key driver of like-for-like sales increases that, at least in theory, could last forever. The profit margin went up by 10% on the basis of several possible factors like better marketing, improved economic conditions in the UK and Ireland where the economy is growing each year by 3-4% (Heritage, 2007, p. 381). The margins for the Group most likely reflect the profits earned from selling to franchisees the ingredients used for making pizzas and from the franchise fees paid by those who opened new stores during the year. Offhand, 13-15% margins are rather small for a food operation, where profit margins are in the range of 20-30% as shown by the margins of McDonald's (2007, p. 20) in the last eleven years, which means that Domino's gets most of its profit margins from franchise fees and not from sales of ingredients or pizzas through its own stores. The asset turnover was calculated using the sales figure of  £94.965 million and the total capital employed of  £18.265 million which is the total assets less the current liabilities as clearly stated in the balance sheet (p. 30). This means that every  £1 invested in the company’s assets returned sales of  £5.19 or over five times the total capital employed in the business. ...

As the Domino's report also shows (p. 27), the company spends 14 million on administrative expenses and 8 million for distribution. Asset Turnover = 5.19 times (3.61 times in 2005) The asset turnover was calculated using the sales figure of 94.965 million and the total capital employed of 18.265 million which is the total assets less the current liabilities as clearly stated in the balance sheet (p. 30). This means that every 1 invested in the company's assets returned sales of 5.19 or over five times the total capital employed in the business. This figure is high, and it has increased quite substantially since the previous year. This figure shows that the company generates revenues with a small amount of assets. This is quite expected given that the main business of the Group is to distribute franchises, carry out quality control processes, and plan the marketing of a product portfolio that is focused on pizzas. The increase from 2005 to 2006 is also interesting, a

Concept Of Collaborative Working Social Work Essay

Concept Of Collaborative Working Social Work Essay Social Work is at an important stage in its development as a profession not only in the United Kingdom but around the world. All professions must be responsive and proactive to changing social and economic climates and conditions if they are to meet the needs of the people they are serving. It is essential for Social Workers to be able to practise in accordance with social work values and to retain a clear professional identity, and at the same time to be able to work effectively with other professional groups and agencies. Although there are many terms used to describe working together with other professions such as joint working, inter-professional working, multi-disciplinary working and inter-agency working the term currently used by the Department of Health publications is collaborative practice (Whittington 2003b). New ways of working that crossed professional boundaries had to be created, in order to allow a more flexible approach to care delivery (Malin et al, 2002). Collaboration in health and social care is a relatively new field of study, with the first major studies being undertaken in the 1980s (Roy, 2001). In health and social care collaborative working is often referred to as Inter-professional working, as it is not just about professionals working together. The patients, clients or service users are a central part of the team. At its simplest the concept of collaboration infers that people from different professional and academic backgrounds form a working relationship for the purpose of enhanced service provision. However, the exact nature of the partnership is likely to be contested, whilst fully integrated joined-up collaborative practice has so far proved elusive. Effective communication is an essential component of the traditional social work roles and responsibilities. It is therefore equally necessary for social workers to also have effective communication skills if they are to promote self-help and empowerment to those whom they are providing a service for. Lishman (1994) reminds us that care managers and providers will have to use a range of communication and interpersonal skills if community care is really to mean care, choice and empowerment of others. Collaborative working implies: conscious interaction between the parties to achieve a common goal (Meads Ashcroft, 2005). It recognises both difference similarity. Collaboration is a process by which members of different disciplines share their skills and expertise to provide a better quality service to patients, clients or service users (Hughes, Hemingway Smith, 2005). The sharing of information means both getting information and giving it. The act of gaining information in Social Work is an essential task the information gained can be used for numerous purposes such as: Making an assessment of need or risk Writing a report Planning an intervention To justify obtaining resource The something or benefit is sometimes called collaborative advantage, and it can be seen as the fuel of collaborative working the greater the potential or actual advantage gained by all parties, the greater the levels of energy fuelling the collaboration. According to Wilson (2008) and Hughes, Hemmingway Smith (2005) inter-professional and collaborative working means considering the service user in a holistic way, and it benefits the service user when different organisations, such as Social Workers, District Nurses, Occupational Therapists and other health professionals come together to provide a better service. These definitions describe collaborative working as the act of people working together toward common goals. Integrated working involves putting the service user at the center of decision making to meet their needs and improve their lives (Dept. Health, 2009). Effective collaboration and interaction will have positive outcomes within a working environment for both the teams working together and the service user. Agencies should be encouraged to share information to ensure that all needs of the service users are met but also to ensure the safety of the service user and the other teams involved. Caring for People (Dept. Health, 1989) stated that successful collaboration required a clear, mutual understanding by every agency of each others responsibilities and powers, in order to make plain how and with whom collaboration should be secured. The government has been promoting inter-agency and collaborative working since the late 80s which also saw a change in the policies set forth by the governments and a legislative backdrop was created to promote self-collaboration between companies. The stated aim has been to create high quality, needs-led, co-ordinated services that maximised choice for the service user. (Payne, 1995). Recent events and media outcries have focused collaborative working solely on Social Work as stated in Pollard, Sellman Senior (2005) and when viewed as a good thing, it is worthwhile to critically examine its benefits and drawbacks. (Leathard, 2003). The old government set forth plans to modernize the Social Services as well as update the NHS. A clear indication of this can be found in NHS Plan (Dept. Health, 2000) and Modernizing the Social Services (Dept. Health, 1998a). This was not in fact a new plan it was part of a growing emphasis stemming from the 1970s. The death of Maria Coldwell in 1974 meant there were questions asked why professionals were not able to protect children who they had identified as most at risk. The Cleveland Inquiry 1988 resulted in the direct opposite of 1974 when the methods of the Social Services were deemed too strict and over powering, it was deemed that children were removed from their families when there was little concrete evidence of harm or abuse (Butler-Sloss, 1988), with too much emphasis put on the medical opinion.

The Munro Report (2010) stated that other service agencies cannot and should not replace Social Workers, but there is a requirement for agencies to engage professionally about children, young people and families on their caseloads. The Childrens Act 2004 was introduced after the public inquiry into the death of Victoria Climbià © in 2000; the same public inquiry also resulted in the Every Child Matters movement. The failure to collaborate effectively was highlighted as one of many missed opportunities by the inquiry into the tragic death of Victoria Climbià © (Laming, 2003) and Baby Peter (Munro, 2010). Expressing what you all want to achieve in clear, outcomes-oriented language, and being able to continually recheck those outcomes as your work together proceeds, is the single most important key to successful collaboration. However, it is actually quite difficult to express outcomes in ways that are unambiguous and clearly understood by all of the potential or actual collaborators. The quality of communication is vital. Poor communication is often behind many of the disputes that threaten to stall collaborative working relationships. Clear lines of communication need to be established across the institutions that make up a consortium to ensure everyone is aware of and is able to carry out the accepted policies and procedures. Accountabilities, in particular, should be well defined. Participation and involvement of service user is also critical in the Social Work field. This after all is the main beneficiary of the collaborative working scheme and your goal as a Social Worker is to meet their needs and goals. If you show the service user respect they too will give you a mutual respect which will allow the Social Workers and other elements of the collaborative team to achieve their common goals. However beneficiaries do not have to be aware that an activity is being delivered in partnership for the partnership to be successful. Regular reviews and users feedback can help measure its impact. Collaborative advantage will be achieved when something unusually creative is produced perhaps an objective is met that no organisation could have produced on its own and when each organisation, through collaboration, is able to achieve its own objectives better than it could alone. (Huxham, 1996). Huxham was showing that collaboration will work when it is done properly, and when we as Social Workers put aside any prejudices that are under lying in our working mentality and also our personal mentality, we will work well with other fields and practices to form a more efficient and organised service. By learning with, from and about one another practitioners can understand respective roles and responsibilities, generate mutual trust, strengthen relationships and improve collaborative practice (Barr et al 2005). To summarise and conclude the development of collaborative working will undoubtedly require a change in culture and values amongst health and social care professionals; however it is working and developing quickly and for the better of not just the collaborating agencies but also for the service users.

Perceptions of the Cold War Essay -- Cold War Interviews

This is an interview project with the goal of discovering how people understand the Cold War. In this essay, I will analyze how people understand the Cold War today. I will explain to what extent their definition or understanding of the Cold War differs from the definition provided. I will explain why the respondents’ understanding of the Cold War is different from the way the Cold War is defined in this course or explain why the respondents’ definition is similar to the way the Cold War is defined in this course. This course defines the Cold War as the geopolitical tensions, and proxy wars fought between the United States and the Soviet Union. The Soviet Union and the United States repeatedly annoyed each other through political scheming, military alliances, spying, publicity, arms accumulation, financial aid, and proxy wars between other nations, but did not fight directly during the Cold War (John F. Kennedy Presidential Library and Museum, n.d.). The Cold War is a title that was given to the communication that established for the most part between the United States and the Soviet Union after World War II (Trueman, 2013). The Cold War began in 1945 and ended in 1991 (History Rocket, 2012). The Cold War began because the communist nations did not permit fundamental human freedom, so the United States had hostility against the communists (History Rocket, 2012). The increase in weapons of mass destruction had many worried. The Cold War defined American political view and molded foreign policy (Naranjo, 2014).

Clustering Techniques in Oodbms (Using Objectstore)

Introduction Performance of a database can be greatly impacted by the manner in which data is loaded. This fact is true regardless of when the data is loaded; whether loaded before the application(s) begin accessing the data, or concurrently while the application(s) are accessing the data. This paper will present various strategies for locating data as it is loaded into the database and detail the performance implications of those strategies. Data Clustering, Working Sets, and Performance With ObejctStore access to persistent data can perform at in-memory speeds.In order to achieve in-memory speeds, one needs cache affinity. Cache affinity is the generic term that describes the degree to which data accessed within a program overlaps with data already retrieved on behalf of a previous request. Effective data clustering allows for better, if not optimal, cache affinity. Data density is defined as the proportion of objects within a given storage block that are accessed by a client durin g some scope of activation. Clustering is a technique to achieve high data density. The working set is defined as the set of database pages a client needs at a given time.ObjectStore is a page-based architecture which performs best when the following goals are met: †¢ Minimize the number of pages transferred between the client and server †¢ Maximize the use of pages already in the cache In order to achieve these goals, the working set of the application should be optimal. The way to achieve an optimal working set is via data clustering. With good data clustering more data can be accessed in fewer pages; thus a high data density rate is obtained. A higher data density results in a smaller working set as well as a better chance of cache affinity. A smaller working set results in fewer page transfers.The following sections in this paper will explain several clustering patterns/techniques for achieving better performance via cache affinity, higher data density and a smaller wo rking set. NOTE: clustering is used in this paper as a concept of locality of reference. The term is not being used to refer to the physical storage unit available in ObjectStore. ObjectStore does present the user with a choice for location of allocations: with the database, within a particular segment, within a particular cluster. For the remainder of this paper, the discussion of cluster is a conceptual one, not the ObjectStore physical one.Database Design Process Database design is one of the most important steps in designing and implementing an ObjectStore application. The following steps are pre-requisites for a database design: 1) Identify key use cases (ones which need to be fast and/or are run frequently) 2) Identify the object(s) used by the use cases called out in step 1 3) Identify the object(s) that are read or updated during the use cases called out in step 1 The focus of clustering efforts should be on the database objects which are used in the high priority use cases identified above.Begin to cluster based on one use case, and then validate with others. The database design strategies which lend themselves to achieving the optimal working set are: †¢ Clustering †¢ Partitioning There are several different types of techniques which result in data being well clustered: †¢ Isolate Index †¢ Pooling †¢ Object Modeling Data Clustering Clustering is a technique used to achieve high data density. Another definition of clustering is a grouping of objects together. If a use case requires objects A, B and C to operate, then those objects should be co-located for optimal data density.If upon loading the database, those objects are physically allocated close to one another, then we say we have clustered those objects. Assume that the size of the three objects combined is less than the size of a physical database page. The clustering leads to high data density because when we fetch the page with object A, we will also get objects B and C. In this particular case, we need just one page transfer to get all objects required for our use case. To accomplish good clustering, one must know the use cases and the objects involved in those use cases.Given that knowledge, the goals of clustering are: †¢ Cluster objects together which are accessed together †¢ Separate (de-cluster, or partition – we will discuss partitioning in detail later in this paper) objects which are never accessed together. This includes separating frequently accessed data from rarely accessed data. Partitioning Partitioning is a strategy to isolate subsets of objects in different physical storage units. By definition, if two objects are in different partitions, they are de-clustered. The two goals of partitioning are to gain isolation and to increase data density.Isolation is desirable when concurrent access is required. The scope of this paper is not intended to cover concurrency. For that reason our discussion of partitioning will be rather brief. Although partitioning is intended for isolating objects, its use can improve data density. This may seem, by definition, to be counter intuitive. Let us use an example to illustrate. Imagine a grocery store. If you were in need of a box of cereal, you would go down the cereal aisle. If the grocer has done his job correctly, the aisle (or some number of shelves in the aisle) will be populated ONLY with boxes of cereal.Because other items have been located in their respective aisles/shelves, the entire cereal aisle is dense with cereal. If the grocer had not done the job correctly, a given section of a shelf might have (for instance) boxes of noodles, cans of vegetables, and bags of chips. In this scenario, the shelf does not have good data density for the goal of obtaining a box of cereal. Recall the definition of data density: the proportion of objects within a given storage block that are accessed by a client during some scope. Our scope is to obtain a box of cereal. Our storage block is the aisle or a shelf. If the shelf in question contains many items other than cereal, then we have poor data density. If, on the other hand, we partition the non-cereal items to be in different aisles, then the cereal aisle would contain only cereal and thus a high data density would Conclusion The way in which data is loaded into the database can have significant impact on the performance of an application. Careful analysis of the use cases for an application should allow key objects to be identified. Once key objects are identified, a clustering strategy can be planned.Several of the techniques presented here can allow for a clustering strategy that will boost performance far beyond any tuning that might be done after the database is loaded and the application delivered. It is often the case that several techniques can be combined; an application need not restrict itself to the use of just one technique. The goal of clustering is to reduce your working set siz e; yield higher data density; and reduce the number of pages which need to be transferred between the application and the ObjectStore server.

The Advantages and Disadvantages of Federalism essays

The Advantages and Disadvantages of Federalism essays Federalism is one way that governments choose to solve the problem of governing large populations and/or diverse cultures. Federalism works by dividing its authority and responsibility, as opposed to a unitary government, in which the central government controls everything. Examples of federalism operating successfully include the United States, One advantage of federalism is that by allowing the central government to delegate many government functions to states or provinces, it has more time to focus on world issues and policies. With such a system in place, the state governments can focus on local responsibilities, which works better because state and local representatives are closer to the issues and problems that affect their population. In addition, it is impractical for a national government to assume it can have one central location; the government can not cover large areas of geography nor can it keep up with population growth. As a result, federalism brings the government closer to the people because the people have easier access to local officials and they also have a greater influence on how local governments govern. Disadvantages of a federal system include the division among subcultures. When individuals of the same mind become concentrated in one area, problems erupt that demand intervention from the federal government. For example, the South generated a strong subculture, which lead to the Civil War. In addition, a single party can sometimes dominate local governments, they seem to block progress at times, and they are more open to corruption. (73) While certainly local governments have the potential to become corrupt and dominating, the advantages and results gained from using federalism as a means of governing prove to be the most successful. ...

In this regard, both simple and multiple regression analysis shows the relationship between the dependent variable against the independent variables (IV: within subject factors e.g. products differentiation, product prices etc.). A business normally comes up with a model based on its operations and then using the available historical data formulates a regression equation which can be used able to predict the future values. An example of a regression model is shown below;SV = ÃŽ ²0 + ÃŽ ²1P + ÃŽ ²2M+†¦+ ÃŽ ²nXi In this model, ÃŽ ²Ã¢â‚¬â„¢s are the coefficients of the various independent variables and which signifies the amount of dependent variable change (in this case sales volumes), either positive or negative, once one of the independent variable’s changes by a single unit. P, product differentiation, and M, market share, are examples of independent variables. ÃŽ ²n shows that the variables can be as many as possible depending on the business itself. According to Jain, C. L. (2000), business forecasting is normally completed through the application of data mining processes where models are used to predict future using existing/historical data from which business potential if projected based on different business activities as well as transactions. To Jain, the sole purpose of data mining is to establish the presence of predictive criteria which might be present if large volumes of historical data are used.

Quantitative Research Tools - Assignment Example These quantitative analyses develop trends for future and guide strategy development and employment. The application of quantitative techniques in providing solutions to identified problems of a case study also validates the theory used to make any suggestion; unlike, qualitative research provides responses based on researcher’s biases (Dul, and Hak, 2008). Â  Since techniques under discussion are objective in nature, application in case study provides results leaving no or least room for subjectivity as for the questions. Hence, providing responses with defined scope of variables involved conclusions and recommendations. Â  Quantitative research is based on the cause and effect relationship. Testing of propositions in the context of the case study is also developed with logic and theories in deductive form. Therefore, instances of the case study are the only factors to impose the effect on the results. This also separates a researcher from posing any influence on the outcome, defining and explaining the variables of the case study under analysis that are usually prone to an extensive deviation on being explored with theory only or even using the qualitative research techniques (Gerring, 2005). Â  The exploration of a case study using mentioned techniques also provides evidence of the level of impact of uncontrollable variables indefinite terms. For instance, application of regression analysis to forecast the trend of sales in two branches of a company in distant areas but with almost identical operations and the most accounted variables would still not yield identical results. This difference in trend provides evidence related to the level of impact arising from differences in scenarios.
