Competitive Advantage Essay -- essays research papers fc

Corporate Strategy "Sources of competitive advantage rarely yield added value that can be sustained over time." The following essay is going to attempt to assess the above proposition and try to find if it is possible to add value continually over a period of time. I will first discuss what competitive advantage is and what it means to a firm. Then I will explain the sources of competitive advantage and how the distinctive capabilities of a firm allow it to sustain added value. The discussion is based on a number of viewpoints from different authors who will be clearly indicated and acknowledged. I begin with explaining what competitive advantage is. So, what is Competitive Advantage? In a number of industries, the average performance of the industry is usually no better than the average performance of industries' as a whole. However particular firms or groups of firms manage to do considerably better than average. In this case, the high performing firm or sub-group has something special and difficult to imitate to offer which allows it to outperform it's rivals. Porter (1985) refers to such special assets as the firm's competitive advantage. "A firm's competitive advantage are those characteristics that allow it to do well even in the face of mediocre industry wide performance and free entry into the industry as a whole." The firm has certain capabilities which allow it to be different from the other firms in the industry. It has certain distinctive capabilities which cannot be reproduced by competitors. However, it is not enough for that characteristic to be distinctive. It is also necessary for it to be sustainable over a period of time. As Oster (1994) points out, " The key success factors in an industry are those assets that allow a firm to outperform it's rivals for a sustained period of time." Competitive advantages are always relative. For example, Sainsbury's has a very slight competitive advantage over Tesco. These firms serve similar markets and they see themselves as members of the same industry and strategic group. Tesco has a competitive advantage over Argyll. In a paired comparison one firm will have a relative competitive advantage over another. The resource based theory of the firm indicates, " If all firms in a market have the same stock of resources and capabilities, no strategy for value creation is... ...ge a firm has in the market.

Outline And Evaluate The Working Model Of Memory

Baddeley and Hitch proposed that memory has 4 components. The central executive, phonological loop, visuospatial sketchpad and the episodic buffer. The central executive decides how to share out and direct attention to incoming information. The phonological loop can be thought of as a maintenance rehearsal mechanism for retaining verbal information. It is sub-divided into two other components, the phonological store (inner ear), which holds acoustically coded information, and the articulatory process (inner voice), which allows for sub vocal rehearsal (words you are about to say).Furthermore, the visuospatial sketchpad (inner eye) is responsible for storing visual and spatial information. In other words, it codes information in images and can create and manipulate visual and spatial images. Finally, the episodic buffer. This component takes information from different sources and integrates them together. For example, Baddeley suggested if we imagine an elephant playing ice hockey, we have to draw out images stored in long term memory and combine them into a moving image.The working memory model is good and is an improvement over the multi-store model. It demonstrates how the short term memory works because it explains how we can store information briefly and simultaneously manipulate it, for example, mental arithmetic. This shows that the model has face validity, which means that the test appears to measure what it is intended to. There is evidence to prove the existence of the phonological loop.Baddeley thought that because longer chunks of information take longer to say, this may affect how much the short term memory can hold, rather than the capacity. This is known as the word length effect and it supports the existence of a phonological loop. However, there are also arguments to suggest weaknesses of the working memory model. The main limitation is the lack of clarity about the central executive. A psychologist argued that the central executive may be more than just one system, possibly consisting of more than one component.This could make the working memory model appear reductionist because it has only been described as being unitary and over simplified. From this, it could be suggested that it is lacking in detail and is not fully reliable. Finally, much of the supporting evidence for this model was by one of the psychologists who proposed it (Baddeley). Here, assumptions could be made as to whether investigator effects play a part as Baddeley may want to prove his beliefs. This means that the supporting evidence many not always be fully reliable.

Essay on Discipline on Children - 3032 Words

Discipline can become a challenge for parents today and choosing the right method is something that parents should take very seriously. Physical punishment is one form of discipline that parents employ. In fact, most parents believe that physical punishment is an acceptable form of discipline (â€Å"The National Child Traumatic Stress Network† 1). On the other hand, there may be some people who oppose physical punishment but is this a good decision to make? In order for parents to make this decision, examining whether this is the best way to discipline a child and their welfare needs to be done. It is important to know when it is appropriate and to what extent physical punishment should be used. Some parents may not realize but the way a child†¦show more content†¦And to recognize these side effects is important in order to evaluate whether physical punishment is effective for children. Another factor to look at is to gain knowledge of children’s views on how they are disciplined by their parents. A study done on children’s view on physical punishment found out that â€Å"parents were inconsistent when delivering family discipline† (Dobbs et al 142). The children felt â€Å"inconsistent application of discipline among siblings †¦ depending on age or gender† (Dobbs et al 142). For example, if one child gets disciplined for something and the other child doesn’t, then the child who gets punished will feel less favored and create more problems. Inconsistency in discipline can confuse the child to know the parent’s expectations. The children also said that parents expect older children to â€Å"’know better’† and there were differences in how boys were punished because parents believe boys are stronger than girls (Dobbs et al 143). This is another example of inconsistent discipline. Parents need to treat their children equally regardless if they are a boy or girl, the discipline should be the same for all. This is one action that parents need to be conscious of because the children do notice them. Children mentioned that parents could be more lenient in some cases such as if there was only one child at home, having visitors or if the parents was in a good mood (Dobbs et al 143).Show MoreRelatedDiscipline And Its Effect On Children1693 Words   |  7 PagesDiscipline is an act by which children learn standards of acceptable behavior and repercussions that they can apply towards greater independence.

Primary lactase deficiency is found to be linked to genetic malfunctioning. Different tests are used by the doctor to identify this deficiency. For example, stool acidity test, hydrogen breath test and lactose tolerance test. There is no specific treatment for this disease. However, symptoms can be monitored and controlled by providing preventive diet. A specific diet lacking lactose is given to the patient in order to avoid occurrence of the symptoms.
