Market Structure and the Role of Government Assignment

Market Structure and the Role of Government - Assignment Example This research will begin with the statement that the term ‘market structures’ refers to a particular social organization which operates between buyers and clients in any given market. Others define market structures as models that govern social organization between clients and businesses in a market. Since the four market structures are perfect competition, monopolistic competition, oligopoly and monopoly, the characteristics of these market structures differ. In perfect structure, supply and demand as competitive market forces control prices in the market and output levels of produce rendered by competitive firms. In both perfect and monopolistic competition and structures, there are multiple participants and the commodity of trade is homogenous. Monopolistic competition is an intermediary between the two extremes that characterize monopolistic and competitive markets. Herein, there are several firms each with small proportions of market share and an extent of different iated products. These competitive firms are also price makers. In a monopoly, the product of trade is one, while in an oligopolistic market structure, a number of firms maintain control over the market share. There are neither competitors in a monopolistic market nor close substitutes for the product. In an oligopoly, there is a tendency to compete on non-pricing criteria which include advertising, gift certificates, packaging, and transportation.

Police Leadership and Code of Silence Essay Example | Topics and Well Written Essays - 750 words

Police Leadership and Code of Silence - Essay Example Also, the study identifies other ways additional to the proposed ones to handle the code of silence. The paper also, analyzes effectiveness of a properly led police organization. Proper leadership within the police department can make a positive difference in the police organization in regards to, handling the code of silence. This could be made possible by doing the following; ensuring accountability to all those in the police department whereby all those in the police department should be held responsible for their actions. This will make them responsible as they will be answerable for whatever action they take. Also, strong disciplinary actions should be taken against those who violate human rights; this will enable the policemen to ensure that do their duty responsibly and do not in any way break the rule on human rights. With the introduction of socialization, the police leadership would have greatly contributed in handling the code of silence; this through psychological testing where they are subjected to a screening mechanism both while in training and when they are on duty. This will ensure the police officers are aware of the limits that they cannot break. Police supervision should also be embraced. Police officers should be supervised while they are carrying out their duties to ensure they do their duties diligently without any harm to the community and in accordance with the set rules and guidelines. Other than this, the community and the police should socialize and work together. Here, police officers and the community will live as friends. This will ensure the hatred between the community and police officers is ironed out and that the two groups, police and the community, work together in fighting crime. It will enable the police to give better services to the community (Stojkovic, et al., 2002). Police supervision is an essential part of the police department in handling the code of silence. It is necessary in that the police officers will be acco untable in what they do to their front line supervisors. This will ensure there are no favors’ in case handling and in turn ensure that justice is achieved. Supervision is also crucial in ensuring that police officers follow rules while carrying out their duty; this will eliminate the blame game and make it easy to identify those who break the law. Another reason why police supervision is important is to ensure that the officers get the best and the required training. This will equip them with the necessary skills and knowledge to handle the citizens. Supervision also promotes integrity; where the officers do and say only what is right. This will help eliminate cases like that of Frank Jude where the police covered up for each other. Police supervision is important in that it promotes justice because the wrong doers are punished (Stojkovic, et al., 2002). Police organizations are not different from other organizations when it comes to the code of silence. This is because the organizations have a set form of leadership and seniors to whom they should be accountable just like the other organizations. There are other ways to address the code of silence issue in the police organization. One such way is ensuring that there is a set of standards to be followed. This will ensure that the officers adhere to the standards and know whenever they are breaking them. Another method is the introduction of refresher courses; where the office

Transition temperatures in toughness Research Paper

Transition temperatures in toughness - Research Paper Example This method uses the fault size, as well as features, constituent geometry, loading state of affairs and the substance property known as fracture toughness to calculate the capacity of a constituent containing a fault to oppose fracture (Metallurgical Society of AIME, 2005). Samples having typical proportions but dissimilar complete size bring into being dissimilar standards for KI. This comes about because the pressure states adjoining to the fault changes with the sample thickness (B) in anticipation of the breadth surpassing some critical measurement. Once the breadth surpasses the critical measurement, the value of KI turns out to be comparatively unvarying and KIC , is a accurate material asset which is known as the plane-strain rupture toughness. The affiliation amid stress strength, KI, and rupture toughness, KIC, is comparable to the correlation amid pressure and tensile pressure. The stress strength, KI, embodies the height of â€Å"pressure† at the top of the crack, as well as the rupture roughness, KIC, is the utmost value of pressure strength that a substance under precise conditions that is plane-strain, that a substance can bear up without rupture. As the stress strength factor gets to the KIC value, unsteady fracture takes place. As with a substance’s other motorized properties, KIC is usually reported within reference books, as well as other sources (American Society for Testing and Materials, 2006).    When a substance with a fracture is loaded in pressure, the materials build up plastic tensions as the capitulate stress is surpassed in the area near the fracture tip. Substance within the fracture tip pressure field, located close to an open surface, can distort tangentially that is in the z-path of the representation since there cannot exist any stresses standard to the open surface. The condition of stress is inclined to biaxial, as well as the substance rupture in a distinctive ductile way, with a 45o cut off lip being create d at each open surface. This situation is known as â€Å"plane-stress" furthermore it takes place in comparatively lean bodies where the pressure through the breadth cannot differ significantly because of the thin segment (Metallurgical Society of AIME, 2005). On the other hand, substance away from the open surfaces of a comparatively thick constituent is not liberated to distort tangentially because the adjoining material inhibits it. The stress situation under these circumstances is inclined to triaxial furthermore, there is zero tension at a 90-degree angle to both the tension axis and the bearing of crack transmission when a substance is loaded in pressure. This form is known as â€Å"plane-strain† and is instituted within thick plates. Underneath plane-strain circumstances, substances behave fundamentally, elastic pending the rupture stress arriving at and then swift fracture takes place. Given that slight or no plastic warping is noted, this form rupture is referred to as fragile breakage (Smith, Temenoff & Gall, 2009) . When carrying out a fracture hardiness test, the most widespread test sample designs are the single periphery notch bend (SENB), as well as the compact stress (CT)

Monsters Are Real Donnie Darko Essay Example for Free

Monsters Are Real Donnie Darko Essay DarkoIn storytelling, monsters are used to express the fears and worries of humans. They allow us to discover our values by questioning our morals through imagination and illusion. In both Donnie Darko and Pan’s Labyrinth illustrating real-life monsters Captain Videl and Jim Cunningham enhances our fear of monsters. These villains symbolize the vulnerability we feel as we identify ourselves with the victims of the attack. We can relate each example of monsters to an evolution of our fears throughout our lives. The fear we have of monsters stems from the idea that our moral imaginations shape the danger inside these beastly beings. As children, our vulnerability came from our fears of losing security. The monsters hiding under our beds taunted us with the threat that we’d be eaten and would never see our parents or that our most valued possession would be taken from us. This juvenile fear is illustrated in Pan’s Labyrinth through Captain Videl. He encompasses the threats we felt as children by being controlling and dominating, as he manipulates Pan and she loses her innocence. As we mature and the limits of our moral boundaries widen, the term â€Å"monster† evolves into something more complex. As we enter into adolescence, and later into adulthood, our fears become something less to do with security and more to do with a threat to our happiness. Our moral imagination evokes fears of defeat and failure, a fear that we formulate in ourselves. As we grow older, we also fear the world and others that we cannot control. In Donnie Darko, Jim Cunningham, embodies our fears of a predator. He is the real-life monster we fear everyday with his complex, dark and twisted secrets. Ultimately, both Donnie Darko and Pan’s Labyrinth effectively embody our illusions of fear from childhood to adulthood.

Elements of Childhood in Platos Lysis :: essays research papers

Childhood in the Ancient world was viewed in somewhat of a different light then in the post Greco-Roman world of Europe circa the Medieval age. For this very reason the attitude, language, and style of the writings that are found from the Ancient world must be considered in the context of their time period. Classical Greek writers like Plato comprised extensive works detailing their own teachings through plays or epic poems. Plato commonly would write plays in which his teacher, the famous philosopher Socrates, would commence in extensive dialogue and debate with several other characters. As a student of Socrates, Plato viewed his teacher as a great man who’s teachings were worthy of documentation and most of the present-day knowledge of Socrates’ works are through the writings of Plato. In addition to the philosophical merits of these works, they are also of great importance because they provide the reader with a first-hand look at the attitudes of the Ancient Greeks towards such things as the ancient idea of Childhood.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Lysis,† written by Plato in approximately 380 BCE (the exact year is unknown) is an in depth look, through the teachings of Socrates, at the nature of friendship, desire, usefulness and personal identity. This work is relevant to our course about childhood because the characters in the dialogue that Socrates is speaking with are youths. Socrates reveals through his teachings many of the ancient attitudes towards different aspects of â€Å"childhood.† It is quite apparent that this outlook on children more closely resembles the later ideas of the Renaissance, rather than those found in Medieval history. Due to the obsession with knowledge and learning found in both the Classical and Renaissance eras, those who partook in the learning, the youth of society, held a much higher standing in society than the children of the plague-ridden society of the 14th and early 15th century. This specific work by Plato is particularly interesting and relevant because in the text Socrates talks about childhood in great extent and he seems to have a great appreciation for the young men in Greek society. Socrates also employs a much different style of teaching than that is found in later Judeo-Christian society of Europe. Plato describes this method with great admiration as he writes, â€Å"Socrates maintains his character of a 'know nothing;' but the boys have already learned the lesson which he is unable to teach them, and they are free from the conceit of knowledge.

Operations Management Essay

Introduction A conventional â€Å"bricks and mortar† grocery does not have an online presence, only a physical one. It is built on a face-to-face customer service, and usually always has a building for their operations. A â€Å"brick and mortar† grocery has advantages and disadvantages compared to an online operation, like Theorganicgrocer.com. First of all, their major disadvantage is the overhead. The cost of property, insurance, taxes and staff is much higher for a â€Å"brick and mortar† operation than an online operation. The biggest advantage for a â€Å"brick and mortar† operation is customer security. To a customer, if a company has physical presence, it is seen as more reliable as the company is far less likely to fold overnight and disappear. Online operations on the other hand seem to have maximum exposure and increased profits. Most people however, seem to be under the impression that running an online operation will be an easy task but it can be somewhat challenging. Online operations require less investment and more decision making. Decisions are practically the biggest investments made in the online world. Decisions on what the website should look like, how the products are going to be listed, in which way should the products be marketed would have to be made. Theorganicgrocer.com is based on market research and they focus on dependability, reliability, timeliness, quality, and price. They offer delivery, organic produce and customer specified date and time of delivery. Apart from that, they make sure that their website is constantly updated to reflect the current price. They believe that the key to their success is the simplicity of use of their website. Question 1 What are the comparative operational differences of a conventional â€Å"bricks and mortar† grocery to an online operation? What are the comparative value chains for each system? Comparative Operations| Bricks and Mortar Operation| Online Operation| Display | Customers are able to physically touch and handle items that they are interested in buying.| Customers can only see pictures, graphics and texts that describe the product that they are interested in buying.| Expense| Usually require a bigger budget to lease space, rent property and to pay for other location expenses. | Smaller budget as they do not have to worry about building leases or property expense.| Location| Has a physical business location which limits the amount of customer traffic and foot traffic from shoppers, especially if they are not in a bigger city or metro area| They are not limited to one location and have no geographical boundaries.They can service local, national, and international customers.| Communication| There is face to face interaction with customers. | It is hard to communicate with customers through an online store.Online retailers may have a hard time getting information acr oss to the customer and must be sure to answer all possible questions by the customers through text and graphics on the site so there is no confusion during the purchase. | Technology | Uses the same technology that has been around for years and rarely changes.| Technology is constantly changing and there is a need to keep up and adjust accordingly. | Inventory| Has a large amount of Inventory on hand. Re-orders before the inventory runs out and there is a shortage of stock.| Has a lesser amount of Inventory on hand.Only re-orders when customers request for it.| Work Hours| Have traditional or at least set hours. This helps local customers know when the business is open.| Has varying or non-traditional hours. This is helpful when dealing with an international customer as it accommodates with their time zone. | Reliability| There is a sense of trust and reliability that comes with having your own brick and mortar store.Customers still feel safer buying from a store.| Customers do not feel safe as there are shady websites everywhere.| In a â€Å"brick and mortar† operation, there are primary activities and support activities Primary activities are directly concerned with the creation or delivery of a product or service and can be grouped into five main areas: inbound logistics, operations, outbound logistics, marketing and sales, and service. Each of these primary activities is linked to support activities, which help to improve their effectiveness or efficiency. There are four main areas of support activities: procurement, technology development (including R&D), human resource management, and infrastructure (systems for planning, finance, quality, information management etc.). The chain consists of a series of activities that create and build value. They conclude in the total value delivered by an organisation. The ‘margin’ depicted in the diagram is the same as added value which expresses the way a business differentiates itself through configuration of its value chain. The drivers for product differentiation and value creation are policy choices (what activities to perform and how), linkages (within the value chain or with suppliers and channels), timing (of activities), location, sharing of activities amongst business units’ learning, integration, scale and institutional factors. Eg: – Inbound Logistics (receiving and storing materials for distribution for production) Registration * Provide information Eg.: -Categories Product -Build Database -Paypal Operations (transforms inputs into finished products) Eg.: Advertisement Value Chain Model of E-bay Sales and Marketing (promoting and selling the product) Outbound Logistics (entails storing and distributing finished products) Eg: -Removed Product Eg: -Before Sale Service Service (maintenance and repair of the firm’s goods and services) -Shipment -After Sale Service The ‘Virtual Value Chain’ However in an online operation, value chain goes through three phases. The first phase is Visibility, where businesses co-ordinate, measure and at times control business processes. The second phase is Mirroring Capability, where physical steps in the value chain are substituted with virtual ones to make a parallel value chain in the marketplace with methods that are better, faster, more flexible, and lower at cost. The third stage happens when companies use the flow of information in their virtual value chain to create new customer relationships by delivering value to customers in new ways. There are different approaches to changing the value chain and it is not necessarily shorter. This is called Intermediation. In some cases however, one or two links have been removed in the value chain. For example, a business that had previously sold to retailers via distributors might make a decision to sell direct automatically. This approach is called Disintermediation. In shortening the value chain, it reduces costs and there is a more responsive and efficient service. Online businesses also at times, introduce new steps to the value chain as new players find fresh ways to add value to the process. This is known as Reintermediation. Examples of online operations that take this approach are shopping portals and electronic insurance brokers. The creation of new intermediaries that could not have existed before the arrival of the online business and the Internet is called Cybermediation. Cybermediation comes in categories, including Searching, Price Discovery, Logistics, Settlement and Trust. Examples of online operations that use cybermediation are comparison-shopping sites such as Kelkoo and bank account aggregation services like Citibank. Theorganicgrocer.com bases their business on market research. The payments made by the customers are made online using a protected encrypted facility administered by a national bank. Apart from that, they have a vehicle route that makes sure that deliveries are maximized, and aggregated ordering of stock that only produces products that are ordered and purchased by customers. Theorganicgrocer.com also has a financial system which is a computer application that calculates all the generated profits and all its other needs. There is also another separate computer package that generates advertising material and mail-outs. Question 2 What are the key processes in the online operation? Providing Efficient Services Online operations basically simplifies life for those who do not enjoy shopping, those who are too stressed from work to shop in supermarkets and stores by combining technology with business strategy. Online businesses provide efficient service that eradicates most of the steps in traditional shopping. Online shoppers go on websites while being able to view pictures and descriptions of the product. Customers also have the option of selecting specific items by name, to work from established personal shopping profiles or lists, and to browse through electronic aisles. Apart from that, online operations make it easier for customers by accepting payment in more than one method such as, credit cards, bank debit cards, electronic funds transfers, personal cheques, and money orders. For example, eBay is a company operating on the Internet that allows for vendors of any kind to auction or sell merchandise of a variety of types. People and companies from across the world use eBay to sell items on the website. This allows people shopping for items to search through the various offerings, make bids, or opt to make direct purchases. It has become a great location for looking for hard to locate items, like collectibles. Many people also use the site to search for bargains on used items such as electronics, small household appliances and others. With the exception of a few illegal to sell things, at any given time eBay has a huge selection. Customers can shop by category and by specific item, or they can simply browse listings. Assembling Online Orders Apart from that, online operations will also assemble orders from online shoppers. There are mainly two common models for assembling the online orders, which are the warehouse and store model. A business usually uses a company-owned and operated central distribution warehouse to store, pick up and pack orders for delivery using the warehouse model. The warehouse model is popular among online operations as it reduces overhead costs, generates the lowest-fees possible to customers, and is very efficient. With the store model, orders are picked off the shelves of local retail stores or supermarkets. Grocery Gateway, an online grocery operation uses a direct-to-consumer online shopping model, which is the warehouse model as it uses a market centre to store, pick, and pack the ordered groceries for delivery. The model has a supply chain management system that lets groceries be delivered directly from Grocery Gateway’s market centre to consumers’ doors. The company’s Customer Fulfilment Centre that provides an extensive selection of food, grocery products, and household goods, which improves the company’s inventory and delivery management. The centre also helps manage the company’s growth by allowing more space capacity and helping to improve the company’s accuracies by using technologically advanced radio frequency picking tools, conveyors, and scanners to make sure the processing of orders is fast and accurate. Delivery Lastly, online operations offer delivery. Some online businesses have a delivery computer program that provides time management information and point-to-point directions throughout delivery. The program takes traffic conditions, rush-hour volume, road construction, and other uncertainties that can be predicted into account. Some companies require customers to be at home to wait for the delivery. Not many can be able to stay at home; therefore, other companies offer the option of unattended delivery.

Lack of Self Esteem

Self esteem is defined as regarding oneself as a worthwhile person or a positive evaluation of oneself. Let's examine African adolescents self-esteem based on the following facts; parental marital status, income, family structure and functioning. Is it possible that the above mentioned facts could affect a confidence that is supposed to come from oneself? I believe these facts greatly affect the self-esteem in African boys and girls in different but very significant ways. I choose this topic because it interested me and I'll be free to express my feelings, and I willl like to help those adolescents who are lacking self-esteem with these essay because I know how it feels. I must first start my essay with pointing out where the problem originates. Having grown up in a single parent, middle class income family and being the oldest of two children, I feel that I can now understand why I sometimes felt inadequate with myself. The unspoken pressure to make my mom proud and be a â€Å"good† big sister created this inadequacy. This study definitely helped me understand this pressure and proved that unlike my thought at the time, I was not the only teenager going through this enormous drop in self-esteem. I mentioned some major facts that surrounds lack of self-esteem, 1. the parental marital status,2. the income and 3. the family structure and 4. Family Functioning. these are the functioning perspectives. First, that the self-esteem of boys and girls (boys especially) would be highly affected by their parents’ marital status. Second, that both genders would have higher quality of family functioning than single parent households. The third prediction concluded that the effects of marital status on self-esteem would be less if family income was statistically matched with other families. The last hypothesis predicted that family functioning had a greater effect on self-esteem than family structure. The sample consisted of 200 fifteen year old African children from western part Nigeria with 74 being girls and the remainder boys. Parents were only included in study to provide income and marital status information. Half of the parents were married, 38% were divorced and 12% were single mothers (no single fathers were used). The average household income was #57,500, 20% of the sample had an income less than 20,000 and 35% made over 35,000 a year. The tests that were used to measure the self-esteem and the family functioning measurement of the students were the Multi-Dimensional Self Esteem Inventory (MDSEI) and the Family Environment Scale (FES). The MDSEI is a 200 question test used to assess the individual aspects of self-esteem in each child. These aspects are feelings of competence, personal power, lovability, likeability, self-control, moral self-approval, and body functioning. The FES consists of 90 true or false type questions to determine the environment within the family and it’s functioning. This test has proven accurate many times with African families even though the norms were determined from 285 predominately middle and upper class European American families. Each child was given $10 to partake in the tests and took them whenever was convenient. The results showed that boys with parents who are divorced are mainly at risk of developing a low self-esteem. It also showed that family functioning was directly related to self-esteem in both boys and girls. I believe that this experiment was set up and conducted very well. The experimenters used a sample that was proven to be representative of the population they sought to test, and used testing methods that were tried and true. Testing conditions were not kept controlled but this probably had a minimal effect on the children’s responses. There were no noticeable errors in the experimentation other than the small sample used and its limited application one locale.
