Control Mechanisms - the Disney Company Essay Example for Free

Control Mechanisms the Disney Company Essay Control Mechanisms The Disney Company Bonita Johnson, Christi Cavanaugh, Gloria Aguilar, Hillary McCabe, Jeffrey Harriman MGT 330 January 9, 2012 Susan Mills Control Mechanisms The Disney Company In more than eight decades The Disney Company continues to be one of the largest media and entertainment corporations in the world. Founded on October 16, 1923 by brothers Walt and Roy Disney as a small animation studio, today The Walt Disney Company is one the largest Hollywood studios and owns 11 theme parks, two water parks, and several television networks including the American Broadcasting Company (ABC). The name Walt Disney has and always will be preeminent in the realm of family entertainment. Additionally, The Disney Company continues proudly to provide quality entertainment for all family members across American and around the world. The Walt Disney Company did not become one of the largest entertainment corporations in world without developing secure control mechanisms. The Disney Company has earned its reputation by tight control and although control pervades the company, Disney’s control mechanisms are not considered heavy-handed or condescending. This paper will examine that although The Disney Company enforces strict control mechanisms within its organization, it is also an organization independent in its thinking and approaches. The Walt Disney Company has always, and continues to use control mechanisms to help regulate policy and procedures which contribute toward effectively achieving organizational goals (The Walt Disney Company, 2008). The Disney Company has been widely successful both nationally and internationally for over 70 years primarily through successful implementation of control mechanisms throughout all aspects of the organization (The Walt Disney Company, 2008). The four types of control mechanisms that best serve The Disney Company would be budgetary, financial, management audit, and bureaucratic. The bureaucratic control function is the lifeline of Disney’s corporate structure because it provides the company’s ethical standards, mission statement, and organizational structure. Moreover, bureaucratic control is a constructive system used to influence subordinates and structure reward systems. Budgetary control is a method used by The Disney Company to bring their vision to life. Budgetary control is detailed, step-by-step documentation of a company’s accomplishments or deficiencies by contrasting data. The Disney Company has implemented many ways of using budgetary control before building or acquiring any new real estate. Management audit controls are equally important to The Disney Company particularly if expansion is in their future. The Disney Company uses both an internal and external audit system. Through management audits The Disney Company has a set checks and balances system to ensure all assets are properly maintain and nothing is compromised (The Walt Disney Company, 2008). Financial controls are just as vital as budgetary controls with a company such as Disney. The marketing strategies that Disney employs help to produce revenue for the company thereby stabilizing assets and liabilities. Financial controls also help to make it possible for Disney to build more parks and resorts in the future. These four control mechanisms enforced by The Disney Company helps provide the company with a format in sustaining the company in a profitable direction. Equally important, these four components of Disney’s control mechanisms are the key in keeping the organization focused, and diverting away from any unethical misconduct from their employees.

Timed Efficient Stream Loss-Tolerant Authentication (TESLA)

Timed Efficient Stream Loss-Tolerant Authentication (TESLA) When considered as a security solution for ADS-B, asymmetric-key encryption has two major drawbacks. The first issue is that current asymmetric-key schemes have no compact encryption implementations, and would result in an increase of the transmitted ADS-B message length. The second problem is that unique encrypted ADS-B messages would be required for each recipient. To maintain a fully-connected network of n nodes would necessitate (n2 à ¢Ã‹â€ Ã¢â‚¬â„¢ n) unique broadcasts rather than n in the current system [15], which obviously does not scale well as the size of the network increases. As a possible answer to these two drawbacks, Costin et al. [3] have suggested what they term a lightweight PKI solution. In the lightweight PKI approach, node A transmits its digital signature over n messages, so that after every n messages, the surrounding nodes have received As digital signature. The recipients keep the messages until the entire digital signature has been transmitted and they can authenticate the buffered messages. The authors suggest that the PKI key distribution necessary for this scheme could be done during an aircrafts scheduled maintenance cycle [13]. A security scheme called Timed Efficient Stream Loss-Tolerant Authentication (TESLA) is a variation on traditional asymmetric cryptography that has been proposed for use on broadcast networks [19], [20]. With TESLA, senders retroactively publish their keys which are then used by receivers to authenticate the broadcast messages. A broadcasting node produces an encrypted message authentication code (MAC) which is included with every message. After a designated time interval or number of messages, the key to decrypt the senders MAC is published. Listening receivers who have buffered the senders previous messages can then decrypt the messages that were broadcast. When applied to ADS-B, this technique imposes a time delay on the broadcast due to the need to buffer messages, but it provides integrity and continuity of messages sent over the network. TESLA is an adaption of the TESLA protocol designed for use on wireless sensor networks. The TESLA protocol requires nodes in the network to be loosely time synchronized, with each node having an upper bound on the maximum clock synchronization error. As discussed earlier, asymmetric encryption schemes have high computation and communication overhead, which limit their usefulness as security approaches on the bandwidth-constrained ADS-B network. The TESLA protocol overcomes this problem by employing asymmetric-key encryption through a delayed disclosure of symmetric keys, which results in an efficient broadcast authentication scheme. When one considers the bandwidth and interference limitations on the ADS-B frequency channel, the TESLA design adaptations identify this protocol as a viable scheme for providing security in ADS-B. However, there are two obstacles to applying TESLA to ADS-B. The primary issue is that, while sufficiently good time synchronization could be provided via GPS, it would require modification to the protocol to accommodate the GPS timestamp field. The second problem is that in order for TESLA to be used for verifying the identity of a network node, it needs to be reinitialized which leaves it susceptible to memory- based DoS attacks. In spite of these drawbacks, TESLA is a promising security scheme for integrating into ADS-B. B. Aircraft Address Message Authentication Code The cryptographic solutions PKI and TESLA both have shortcomings in that they require modifications to the current ADS-B protocol. The Aircraft Address Message Authentication Code (AA-MAC) security solution utilizes a standard hash algorithm such as MD5 or SHA and a secret authentication key to perform message integrity [21]. The AA-MAC message source integrity scheme would require a slight modification to the existing protocol in that it would replace the current Aircraft Address (AA) field with the MAC, but the ADS-B message is otherwise unchanged. The AA-MAC approach proposes a different aircraft identification strategy, assigning a unique identifier to each aircraft that is good for the duration of a particular flight. As with PKI cryptographic approaches, the distribution of the secret key presents challenges for AA-MAC. Since MAC requires just one key which is used to uniquely identify a sender on the network, the simplest approach would be to distribute the secret key only whe n an aircraft intends to enter the air traffic control system and ADS-B network. The purpose here is to demonstrate a compatible security scheme that will mitigate threats posed by message injection and modification attacks, which are among the most critical vulnerabilities in the current ADS-B implementation. While AA-MAC does not provide data integrity, it is highly compatible with the existing 1090ES protocol and can be implemented at low cost relative to other security proposals, offering a feasible partial security solution for ADS-B. 4.1.2. Non-Cryptographic Schemes As we have seen, cryptographic security schemes are difficult to implement in a way that are not compatible with the existing infrastructure, primarily due to the problem of key distribution and management. Non-cryptographic approaches to network security avoid the challenge of key management and instead involve either some form of fingerprinting on the physical layer, or a frequency modulation scheme such as spread spectrum. A. Fingerprinting Schemes such as fingerprinting encompass various methods for authentication and identification, either based on hardware or software imperfections or characteristics of the frequency channel which are hard to replicate. Identifying signatures for legitimate nodes on the network provides data useful for the implementation of systems to detect network intrusions [22]. Software-Based Fingerprinting schemes attempt to isolate distinct characteristics of the software operating on network equipment. The development teams for different network equipment manufacturers often take widely varied paths when implementing software on a given device. These differences can be cataloged and later exploited to tell apart dissimilar network devices, and can be used to verify their continuity up to a certain degree. Hardware-Based Fingerprinting approaches seek to identify and catalog unique network hardware differences. Some of these differences can be used for radiometric fingerprinting, which takes advantage of differences in the modulation of a radio signal to catalog unique device signatures. Clock skew is another identifiable hardware feature that can be used to establish uniqueness between wireless devices. Since no two clocks are perfectly synchronized, time difference can be used to create signatures and enable identification. A third category of fingerprinting is Channel/Location-Based Fingerprinting. This fingerprinting method tries to exploit natural characteristics of the communications channel. Various approaches utilizing received signal strength (RSS), channel impulse response (CIR) and the carrier phase have shown that this can be a viable alternative to more traditional authentication and verification measures.

Ecological Change With the Arrival of Europeans in the New World :: American America History

Ecological Change With the Arrival of Europeans in the New World Imagine yourself coming from an overpopulated, intensely manicured development (typical of many Americans) to an Island of immense vegetation and overgrowth. Your job is to develop a productive colony using these unknown plants. Your only guides are the natives of the land - if they are gentle and willing to help. Now forget all you know about ecology and the importance of cultures and think about what you would probably do. What if you had one more chance to go to your native land and bring back with you a few simple things to make your life easier? What would you bring? Most would probably react the same way the Europeans did, bringing seeds and machinery for cultivation with them. The Europeans may have even gone further than needed in their search for a productive product. Europeans were fearful and distrustful of the wild, natural areas. For example, many Europeans considered mountains to be hideous. This was said of the Alps, and many mountainous areas of Europe (Sale 77). They had this agenda to control whatever they could. If the land looked wild it needed tamed to their ideas, even if this made the ecosystem unstable or less productive. The results of their need for control and their lack of knowledge on ecosystems resulted in a reflux of new plants being imported. The most influential plants were the forage or grazing crops. These were brought because the Europeans wanted their own familiar crops to be in the grazing yards. These plants included white clover and "Kentucky" bluegrass. Ironically the Kentucky bluegrass was named so because it preceded west at a faster rate than the colonists, so when they arrived in Kentucky they found it in abundance and named it so. These plants were introduced at least as early as 1685, when William Penn was noted for trying some in his courtyard (2 Crosby 157). These plants spread with the equivalences of weeds. Imported, overgrazing European animals helped in the quick dispersal of these plants. The effect of these new grasses is hard to determine. Many of the indigenous grasses all but disappeared, except for small-untouched areas. The introduced animals helped to pave the way for many of these new plants (2 Crosby, 157). The animals first overgrazed the native plants, which were not adapted for heavy grazing, and then continued overgrazing created a new niche or specialization.

My Grandmother Essay -- English Literature

My Grandmother This poem explores the relationship between the speaker and her grandmother. It focuses on the remorse and guilt she felt - and perhaps does still feel - about the way she behaved towards her on one occasion, and can be seen as an attempt to exorcise this. The poem is divided into four parts: the first stanza describes her grandmother working in the shop; the second the incident which causes her guilt; the third stanza shows her in retirement. In the final stanza, after her grandmother has died, the speaker reflects on herself and her grandmother's life. The first stanza sets the scene - the antique shop reflects the character and life of the grandmother. The words 'it kept her' suggest that it seems, to the speaker, her only reason for living; the grandmother's concern is with surface appearance ('polish was all') not with deep human feelings ('there was no need of love'). Her solitariness is suggested in the fact that it is only 'her own reflection' she sees reflected in the antiques; it is these she lives 'among', not people. The antiques themselves create an oppressive atmosphere - they are 'faded' and 'heavy' in this stanza, and in the final stanza the 'tall/ Sideboards and cupboards' in the 'long, narrow room' take on the air of coffins. Even the sounds of the words the speaker uses contribute - the sibilants in 'the brass/ Salvers and silver bowls' are unwelcoming to the reader, and perhaps betray her disapproving attitude to the shop. But to the grandmother the antiques have great importance. They are 'needed', though never 'used' - they are a substitute for human company, a replacement for love. She takes pride in her possession of them; the speaker's 'wish not to be used/... ...think that the women is treating the girl like she was an antique; "It was perhaps I think a wish not to be used like antique objects ...." In stanza three I think that you can see all the memories actually being revealed to the grandchild; "All her best things in one tong narrow room" It gives us the sense that after she had passed away now the guilt is just kicking in and the old women's life has just began to open. In the very last stanza I think that the very last chapter in the old women's life is beginning to come to an end. Nothing is left in memory of her: "..and no finger marks were there" I think that now her life is over and that her family have been excluded, their lives have had a fundamental change and new dust had just began to settle over the rather cold possessions she seemd to value over her children and grandchildren.

A Good Man is Hard to Find :: essays papers

A Good Man is Hard to Find In â€Å"A Good Man is Hard to Find† Flannery O’Conner tells the story of a family in route to their Florida vacation and the trouble the grandmother gets them in. The grandmother does not want to go to Florida on vacation and tries many methods of changing her son, Bailey’s mind. Although she tries many methods, none of them have the effect on him she desires. Bailey is as stubborn as his mother, completely shutting the door on every proposition his mother makes. When she finally makes some progress in delaying their travels things go horribly. Bailey and his family discover the hard way just how ironic life can be. The grandmother uses many excuses for the family to go to Tennessee instead of Florida on vacation. The first of her many excuses is â€Å"The Misfit†, a serial killer that has escaped from prison and is headed toward Florida, claiming that she would never take her children anywhere near a man like that. This didn’t have the desired effect on Bailey so she explains to him and his wife how the children need more variety and they should take the children to see different parts of the world, East Tennessee for example. Once again her plea to Bailey and his wife had no effect. Even after they had left home she continued to try and divert them from their coarse. Finally succeeding when she convinced the children they would like to visit an old plantation home she had visited during her own childhood. There were many clues as to what was unfolding during the story, although one would have trouble noticing them upon initial reading. The first of the clues was, of coarse, the mentioning of â€Å"The Misfit’s† escaping from prison. As the family was eating at a small restaurant the second clue was given. The owner was discusing with grandmother the criminal nature the society has compared to the old day an example was three men had stolen gas from him only a few days earlier. The next clue came after grandmother and the children persuaded Bailey to turn off the main road in search of the old plantation home. The road had not been driven on in months, suggesting the perfect, deserted, hiding places for escaped prisoners. While traveling down the dirt road grandmother remembered that the house was actually in Tennessee, not Georgia.

A pleasurable environment

AN ASSESSMENT OF THE IMPACT OF POLICY AND LAW IN THE MITIGATION OF ENVIRONMENTAL CRIME.An person ‘s character is determined by his life status, it is no secret that the environment an single finds himself has an tremendous influence on his character, which could be either positive or negative. Our vision of holding a enjoyable environment is being ruined by actions committed by either persons, corporate organic structures or concern administrations that disrupt the peace and hygiene of our environment, these actions are referred to as environmental offense. ( House of Commons Environmental Audit Committee 2005, p.8 ) . An Environmental offense is an environmental issue several writers and authors have made effort to specify from their ain point of position. An environmental offense as defined by the Staffordshire Moor lands District Council ( 2009 ) is an improper act which ruin the visual aspect of some portion of the environment, it could take to pollution of the environment, wellness and safety concerns and it can hold a negative consequence on the enjoyment of our territory. Situ and Emmons ( 2000, p.3 ) refers to environmental offense as an inadvertence that violates the jurisprudence and attracts condemnable test and countenance. This offense endangers the safety of persons both physically, wellness wise and environmentally. Clifford ( 1998, p.26 ) believes that an environmental offense is an knowing act committed to potentially do injury to the ecological and biological systems of the environment and besides for the intent of procuring concern or personal benefit, While the Sixth study of the Environmental Audit Committee states that environmental offense comprises all offenses either formed by statues or developed under the comm on jurisprudence that relates to the environment. Environmental Investigation Agency ( EIA ) ( 2009 ) goes farther to specify environmental offense as the interruption of international pacts designed to command trade in substances harmful to the environment or bound trade in rare species or improper Acts of the Apostless which cause direct injury to the environment straight. Stratford -on-Avon District Council ( 2009 ) defines environmental offense as a type of anti-social behavior that affects the value of life of the community and environment where the offense occurs and enhances the fright of offense. This is similar to the definition of environmental offense by Warwickshire Council ( 2009 ) as activities that are against the jurisprudence and are harmful to the quality of unrecorded and the environment. Environmental Crime may include the undermentioned and many more: Fly tipping Graffiti Littering Fly-posting Abandoned Vehicles Dog fouling Panpipes Vandalism Noise Pollution Extra Side Waste House holders Duty attention Wild life Crime Pollution Crime Improper waste disposal Oil spills Dumping into Oceans, Streams, Lakes or rivers Improper handling of pesticides or other toxic chemicals Burning Garbage Falsifying Lab informations pertaining to environmental ordinance Sourced from assorted writers: Daventory District Council ( 2009 ) , Interpol ( 2009 ) , LawyerShop ( 2008 ) , Straford – on- Avon District council ( 2009 ) , Working Borough Council ( 2008 ) . These are really of import environmental issues that affect our environments merchandise and place. Here one can place several inquiries: Can the most common of these offenses be defined? What chance exists for an environment in which these offenses occur? What has be done by the Law to if non wholly eliminate these offenses at least cut down their happening drastically? What can I make to assist cut down environmental offense in my environment? Violators of the environmental jurisprudence are normally charged with condemnable mulcts, gaol clip, test or other penalty ordered by the local governments. Although fixed punishment mulcts are used as bar to large companies from go againsting environmental Torahs and policy without the hazard of sedate pecuniary penalty, most large companies might happen that noncompliance is more expensive than obeisance to the jurisprudence, while jail clip may be the best manner to penalize persons who participate or commit environmental offense. ( Lawye r store 2008 ) . The Environmental Protection Agency is in charge of enforcement over environmental jurisprudence misdemeanor. ( Lawyer Shop 2008 ) . There are offenses that wild occur in our environment which have largely been considered by bulk as environmental offenses, offenses such as: Fly tipping: This could be referred to as illegal dumping of family waste such as old house clasp contraptions ( electric refrigerators, rinsing machines, carcase of dead animate beings, old Surs, vehicle parts ) oil, asbestos sheet and all kind of chemicals are non left out. ( Environmental Agency 2009 ) . This offense cost land proprietors an estimated 100 million annually and local governments an estimated 44million annually to clean up. ( Environmental Agency 2009 ) . It besides attracts a punishment a upper limit of two old ages imprisonment and or an limitless mulct ( Liver Pool City Council 2008 ) every bit good as & A ; lb ; 50,000 in Magistrate Court. ( Environmental Agency 2009 ) . There is a national fly tipping database funded by the authorities which is managed by the environmental bureau, it is known as fly – gaining control, entirely for the intents of undertaking fly- tipping. Graffitti: It is referred to as an act of hooliganism which is on the addition, it entails written, painted or scratched on other people ‘s belongings. Persons every bit good as packs leave a signature grade where they visit such as Bridgess, motor ways, public topographic points, and overseas telegram equipment boxes, unoccupied edifices are non left out. ( Solihull Metropolitan Borough Council 2009 ) . Upon strong belief under subdivision 1 of the Criminal Damage Act 1971 the punishment is 10 old ages imprisonment. This offense is so serious that it can be heard in either a Magistrate or Crown Court. ( Solihull Metropolitan Borough Council 2009 ) . A fixed punishment of & A ; lb ; 75, which will be reduced to & A ; lb ; 50 if received within seven yearss from the day of the month which the punishment was issued. ( Solihull Metropolitan Borough Council 2009 ) . Dog Fouling: This is the act of go forthing your Canis familiaris or the Canis familiaris under your attention to foul on tracts and unfastened infinites, with cleaning up after it. This Canis familiaris foul when in contact with the human oculus can do sightlessness ; people might step on it and transport the crud into their places. This offense attracts a fixed punishment notice of & A ; lb ; 50 which you must pay to the council within 14days, else you will be prosecuted. ( Gateshead Council 2008 ) . Persons can assist to look into environmental offense by study an environmental offense in their community to the local governments through their web sites.

Impact of the internet Essay

Since the advent of the internet, the world has experienced many changes in various aspects of life including the social set up. There is virtually no limit to the information that one can access from the internet just from the comfort of ones chair or bed depending on where you are logged in. Getting in touch with people from any corner of the world has been reduced to just a few strokes of the keys and a click of the mouse. The social impacts of these are many. To start with, there is social alienation leading to complete lose of physical touch with relatives and friends. Individuals are tending to keep away from education and work places. The outcome of this is that people tend to lack face to face socialization as they just get locked up behind there computers. According to Brian, people tend to become significantly depressed, stressed and lonely with one another as they spend many hours chatting in the internet (Brian W, 2006). Even though chat rooms in the net provide almost the same interactive approach to socialization, it however lacks the in–person connection necessary for people to develop acceptable social skills. It is feared that this lack of touch will affect the way the young people socialize especially in communities that dictates strong interpersonal relationships whether it is to the families or friends. This is just one good example of a culture that faces being thrown out or being given little significance by the people due to advent of the internet. Another big change brought to the society due to internet is the lose of identity since most people especially in the urban set up are getting strongly attached to the new culture adopted from the internet . Almost all communities uphold good moral standards in the societies. However, with advent of internet, this has been completely put at stake. High percentage of pictures and videos in the net are pornographic in nature. There are new cultures coming up in the society like establishing online friends. This is common with the many social sites like nimbuzz, tweeter and facebook. Furthermore, dating culture has shifted to the net where there are many sites to look for soul mate. The ease with which people access the friends highly jeopardizes the morality of the society. Politically the freedom of flow of information is suggestion of the democratic level in a country. The internet is one of the technological means in the area of information and knowledge revolution. The internet therefore bears political culture in many meanings. As a fast and handy way of disseminating information, many governments have started using the internet to reach out to the public. There are various government sites with government information. In addition, many people converse about political issues over the net through chat rooms and networking sites. Internet is an available means through which people concerned with politics communicate since it has a gigantic storage capacity (Hasan A, 2005). The internet is an arena that has experienced rapid growth economically. The net is no longer just a place for getting simple information and walk away. It has turned out to be taking the place of learning institutions. It is like a playing field full of games and even a shopping mall full of goods of all sorts. Actually, there is a lot of business carried out in the net. Various companies’ enterprise on providing internet services. They host the internet backbones acting as internet access points, service providers between countries and continents (Andrew O, 1998). They reap a lot profit due to the increasing high demand for internet services, though there is a lot of competition as more people also venture in to get the benefits.
