Token Economy Essay Example

Token Economy Essay Example Token Economy Paper Token Economy Paper The mode of action of Token Economy aims to increase the frequency of a patients desirable behaviours and decrease that of the undesirably behaviours. Tokens are used to dignify reinforcement and are used as part of a reinforcement schedule. Punishment is implemented by the withdrawal of tokens. There are six main steps: 1. the target behaviour is identified (reinforcement or punishment)  2. the nature of the token is identified  3. depending on how many tokens individual receive over the day, they will get a certain number of desired items.  4. the exchange rate is determined (20 tokens for 1 chocolate bar)  5. the location and time of day in which the tokens are exchanged is determined. Allyon and Azrin (1968), pioneered the Token Economy system, found that tokens were most effective when associated with behaviours already in a patients repertoires.  OLeary et al (1969) had no success witgh a behaviour modification programme byt found that a Token Economy system reduced disruptive behaviour in 5 out of 7 children studied.  Token Economies are important because, even though the introduction of chemotherapy in the 1950s meant that mental patients could live in community settings, this transition to community living required more than symptom reduction; living skills also had to be improved. (Lecomte et al, 2000). Most studies do not indicate whether desirable behaviours continue when tokens stop or whether the learning that takes place is an institutional setting generalizes to other settings. Furthermore, there is the issue of cure. Behaviour may change, which helps an individual to conduct a more normal life, but the mental illness remains (Comer, 2002). The method is expensive and time consuming: maintaining it required intensive training and concentrated effort, whereas simpler behaviour modification techniques may be just as effective and easier. Finally there is the problem of establishing effective rewards. To be successful, these must be tailored to the individual.  Like behaviour modification programmes, Token Economy is manipulative; Corrigan (1995) claimed that they are also abusive and humiliating. Withholding privileges and basic rights has been rules unethical by US courts (Emmelkamp, 1994).

Strategic Choice and Evaluation - Research Paper Example egmenting the customers and identifying the target market and the gap analysis (identify the lacking) are the part of identifying the strategies (Kozami, 2002). B&G Food is a well-known brand all over the United States, and its current position in the market is stable i.e. there is no potential for growth and no possible decline in the market for B&G products. There is a need for urgent actions in order to increase the opportunities to expand and also grasp the market share. B&G being a very old company in the market, and it has the potential to grasp the most of the market share. B&G Foods is lacking with some of its core plans that need to be amended and reconsidered. For example, their Promotional and Marketing Strategies are not well designed and implemented. The need of establishing new products and service outlets is essential. Moreover, hiring skilled and specialized workforce and conducting training and development programs for employees are essential. B&G Foods can also expand its product line to attract new customers. B&G Foods has to maintain a proper Promotional and Marketing strategy. The potential consumers would get to know the products and services through the promotions, and the overall sales could be raised. The mediums that can be utilized by B&G Foods can be the online advertisement, TV commercials, newspapers ads, promoting the products and services through billboards, etc. Once the strategies are being followed, the core part is to monitor them and evaluate the outcomes. It will help better in implementation, and the feedback of the consumers can also be gathered regarding the particular strategy. There is a need of hiring skillful management. The process of the recruitment must be strict, and the best candidates must be selected for the Job. The skilled workforce for marketing and promotional strategies will help handle the work effectively and efficiently. The other benefit of hiring an expert workforce is that the new and attractive

Knowledge Management Essay Example | Topics and Well Written Essays - 750 words - 6

Knowledge Management - Essay Example Some of the examples of changing the culture of an organization include how all employees assembled in the main board room every Friday which was to be changed in the up coming quarter, owing to financial expenditures. They discussed organizational matters in a very informal manner but the Managing Director decided to do it in the form of a virtual group which was created and everyone was asked to subscribe it to receive instant updates (Drucker, Garvin, Dorothy, Straus & Brown, 1998). Similar cultural changes do take place within organizations and these are seen as normal measures since organizations are moving ahead with both short term changes as well as the strategic ones. The need is to know what the employees think about them and how ready and willing they would be to embrace the change that is coming about within the organizational cultural realms. As a leader, I would initiate the process of organizational change by finding out what I essentially want to achieve. When I am certain that the aspects that I want to attain are true and genuine for the sake of the organization, and that the change is a positive tangent, then I will manifest it in the truest possible way. I will take all the employees under my aegis and inform them of the management decision. When this has been done, I will ask the middle management to come up with certain policies which are for the betterment of the organization yet are inclined towards attaining a change that is driven by results. I will be making all-out measures to make sure that all employees are on board and provide as much clarity as possible in order to speed up actions. Each of these stages can take up to about 15 days which would mean that the organizational change is a process spanning up to about 3 months. Since there would be five to six different steps that will be undertaken

Packet-Hiding Method for Preventing Selective Jamming Attack

Packet-Hiding Method for Preventing Selective Jamming Attack Abstract The open nature of the wireless medium leaves it vulnerable to intentional interference attacks, typically referred to as jamming. This intentional interference with wireless transmissions can be used as a launchpad for mounting Denial-of-Service attacks on wireless networks. Typically, jamming has been addressed under an external threat model. However, adversaries with internal knowledge of protocol specifications and network secrets can launch low-effort jamming attacks that are difficult to detect and counter. In this work, we address the problem of selective jamming attacks in wireless networks. In these attacks, the adversary is active only for a short period of time, selectively targeting messages of high importance. We illustrate the advantages of selective jamming in terms of network performance degradation and adversary effort by presenting two case studies; a selective attack on TCP and one on routing.We show that selective jamming attacks can be launched by performing real -time packet classification at the physical layer. To mitigate these attacks, we develop three schemes that prevent real-time packet classification by combining cryptographic primitives with physical-layer attributes. We analyze the security of our methods and evaluate their computational and communication overhead. Algorithm 1. Symmetric encryption algorithm 2. Brute force attacks against block encryption algorithms Algorithm Description We propose a solution based on All-Or- Nothing Transformations (AONT) that introduces a modest communication and computation overhead. Such transformations were originally proposed by Rivest to slow down brute force attacks against block encryption algorithms . An AONT serves as a publicly known and completely invertible pre-processing step to a plaintext before it is passed to an ordinary block encryption algorithm. Architecture Existing System Jamming attacks are much harder to counter and more security problems. They have been shown to actualize severe Denial-of-Service (DoS) attacks against wireless networks. In the simplest form of jamming, the adversary interferes with the reception of messages by transmitting a continuous jamming signal , or several short jamming pulses jamming attacks have been considered under an external threat model, in which the jammer is not part of the network. Under this model, jamming strategies include the continuous or random transmission of highpower interference signals Proposed System In this paper, we address the problem of jamming under an internal threat model. We consider a sophisticated adversary who is aware of network secrets and the implementation details of network protocols at any layer in the network stack. The adversary exploits his internal knowledge for launching selective jamming attacks in which specific messages of high importance are targeted. For example, a jammer can target route-request/route-reply messages at the routing layer to prevent route discovery, or target TCP acknowledgments in a TCP session to severely degrade the throughput of an end-to-end flow To launch selective jamming attacks, the adversary must be capable of implementing a classify-then-jam strategy before the completion of a wireless transmission. Such strategy can be actualized either by classifying transmitted packets using protocol semantics, or by decoding packets on the fly. In the latter method, the jammer may decode the first few bits of a packet for recovering useful packet identifiers such as packet type, source and destination address. After classification, the adversary must induce a sufficient number of bit errors so that the packet cannot be recovered at the receiver [34]. Selective jamming requires an intimate knowledge of the physical (PHY) layer, as well as of the specifics of upper layers Modules:- 1. Network module 2. Real Time Packet Classification 3. Selective Jamming Module 4. Strong Hiding Commitment Scheme (SHCS) 5. Cryptographic Puzzle Hiding Scheme (CPHS) Module Descriptions Network module- We address the problem of preventing the jamming node from classifying m in real time, thus mitigating Js ability to perform selective jamming. The network consists of a collection of nodes connected via wireless links. Nodes may communicate directly if they are within communication range, or indirectly via multiple hops. Nodes communicate both in unicast mode and broadcast mode. Communications can be either unencrypted or encrypted. For encrypted broadcast communications, symmetric keys are shared among all intended receivers. These keys are established using preshared pairwise keys or asymmetric cryptography. Real Time Packet Classification Consider the generic communication system depicted in Fig. At the PHY layer, a packet m is encoded, interleaved, and modulated before it is transmitted over the wireless channel. At the receiver, the signal is demodulated, deinterleaved, and decoded, to recover the original packet m. Moreover, even if the encryption key of a hiding scheme were to remain secret, the static portions of a transmitted packet could potentially lead to packet classification. This is because for computationally-efficient encryption methods such as block encryption, the encryption of a prefix plaintext with the same key yields a static ciphertext prefix. Hence, an adversary who is aware of the underlying protocol specifics (structure of the frame) can use the static ciphertext portions of a transmitted packet to classify it. 3. Selective Jamming Module We illustrate the impact of selective jamming attacks on the network performance. implement selective jamming attacks in two multi-hop wireless network scenarios. In the first scenario, the attacker targeted a TCP connection established over a multi-hop wireless route. In the second scenario, the jammer targeted network-layer control messages transmitted during the route establishment process selective jamming would be the encryption of transmitted packets (including headers) with a static key. However, for broadcast communications, this static decryption key must be known to all intended receivers and hence, is susceptible to compromise. An adversary in possession of the decryption key can start decrypting as early as the reception of the first ciphertext block. 4. Strong Hiding Commitment Scheme (SHCS) We propose a strong hiding commitment scheme (SHCS), which is based on symmetric cryptography. Our main motivation is to satisfy the strong hiding property while keeping the computation and communication overhead to a minimum. The computation overhead of SHCS is one symmetric encryption at the sender and one symmetric decryption at the receiver. Because the header information is permuted as a trailer and encrypted, all receivers in the vicinity of a sender must receive the entire packet and decrypt it, before the packet type and destination can be determined. However, in wireless protocols such as 802.11, the complete packet is received at the MAC layer before it is decided if the packet must be discarded or be further processed . If some parts of the MAC header are deemed not to be useful information to the jammer, they can remain unencrypted in the header of the packet, thus avoiding the decryption operation at the receiver. 5. Cryptographic Puzzle Hiding Scheme (CPHS) we present a packet hiding scheme based on cryptographic puzzles. The main idea behind such puzzles is to force the recipient of a puzzle execute a pre-defined set of computations before he is able to extract a secret of interest. The time required for obtaining the solution of a puzzle depends on its hardness and the computational ability of the solver. The advantage of the puzzlebased scheme is that its security does not rely on the PHY layer parameters. However, it has higher computation and communication overhead We consider several puzzle schemes as the basis for CPHS. For each scheme, we analyze the implementation details which impact security and performance. Cryptographic puzzles are primitives originally suggested by Merkle as a method for establishing a secret over an insecure channel.

Should Vietnam Concentrate on Tourism for its Economic Development?

Vietnam is in the republic of South East Asia, bordered by China on the north, by the South China Sea on the east and south, and by Cambodia and Laos on the west. Officially the Socialist Republic of Vietnam, its area is 331,690 sq km (128,066 sq mi). Hanoi is the capital of Vietnam and Ho Chi Minh City is the country's largest city. Ho Chi Minh is at the coordinates 106 degrees south, 10 degrees west on a map. There many ways in which the tourist industry would benefit Vietnam as a whole. Tourism, of course, makes a huge amount of money; it could be hundreds of millions every year. For example places like Barcelona have become huge, great cities full of people thanks to the money made from tourism. Also read this  Cheating in a Bottom Line Economy Tourism also creates lots of new jobs for the people living in the country and some people who will come to work in Vietnam from other countries. The new jobs will trickle right down to the farmers who grow the food for the people who sell food to the hotels. This means it will be very good for agriculture, giving farmers more money to buy more land and grow more crops. People who have jobs in other industries making products for MEDCs like workers in Pepsi factories, could easily switch to having an easier but better paid life in the tourist industry. Concentrating on tourism alone might still work for Vietnam. If the locals take part in planning and decision making, the tourists are responsible in Vietnam and the government sets policies and plans ahead for it then it could work quite well. But even if it does work then there will be some downsides. Tourists generally makes quite a lot of mess wherever they go, they can destroy some of the beautiful beaches and rainforests. The rainforests themselves will have to be cut through for new highways, towns and airports. With the new highways would, hundreds upon thousands of cars and trucks, which would eventually pollute the country, turning tourist away from it. The effect on the countries fishing industries could be catastrophic. The South China Sea could be way over-fished, so hotels and resorts would have to import fish, driving prices up and making the appeal of fresh fish vanish. The effect on individual families could be bad too; the father could have to move away to a bigger city, potentially leaving the family behind, splitting the family up. This could happen to thousands of families. If the tourist industry failed then the country would have nothing to fall back on, it would use up all its money and end up back at the start. Unfortunately, most of the money tourists spend in foreign countries is immediately used to import more food, equipment and resources for the hotels and nightclubs. This leaves little money left over for the local people and economy. In conclusion I think that Vietnam should seriously consider Tourism as a big part of their economy but I don't think that they should ignore everything else. If given the time, Vietnam could become just as unwieldy as Japan in the computer services/games industry or as big as America or Germany in the automotive industry. I think the best effect of tourism in Vietnam would be the huge amount of jobs it creates and could make thousands of informal jobs vanish for formal tourism jobs. The worst thing about tourism in Vietnam would be the huge amount of damage that would be inflicted on such a beautiful landscape thanks to all the cars, litter and sewage caused by the tourists. In other words tourism could be great for the country but disastrous as well. But I still think concentrating on tourism would be a bad idea for Vietnam's economy.
