Tourism in the Republic of Cyprus Research Paper

Tourism in the Republic of Cyprus - Research Paper Example This leads to one thing; sustainable tourism. Sustainable tourism is defined to as the move towards making less impact on the environment and culture in a given country while at the same time benefiting economically from it. The main objective is to develop tourism to the point where can continually have a great experience from the sector (Trejos & Chiang, 2009). Different countries have varied policies towards sustainability in tourism. The height of the problems coming from tourism guides policy making in every country. In this paper, we take the case study of Cyprus and the policies that they have adopted towards sustainability in tourism. Cyprus continues to experience growth in the number of tourists visiting the region every year (Gunn & Var, 2002). Its impeccable sites and beauty has made it experience an exponential growth to the number of tourists visiting the region every year. For example in the year 1975, they had close to 47000 thousands of tourists visiting the region. This number is nothing comparable to the 2.25 million tourists visiting the region in the year 2000 (Gunn & Var, 2002). The number has continued to grow in the recent decade, raising environmental concerns. While one can not dispute the economic benefits of such a growth, mass tourism has taken a toll on the environment in Cyprus. For example, in the year 1988, the income from the tourism sector estimated at 880 dollars. Today, the sector accounts for 20% of the overall income in the country (Gunn & Var, 2002). Features such as resorts for various groups, water parks with dolphins gracing them and archeological sites attract millions of people all over the world. The enormous numbers of people have had an impact on both on the culture of the people and the environment as a whole. For one, the noise from the tourists has been unbearable

English - Essay Example To be specific, the villagers never try to realize that their belief in ‘the lottery’ is false. Instead, the blindly accept the tradition and happen to be the victims of the same. The speaker in the work by Shirley Jackson states that, â€Å"Soon the men began to gather, surveying their own children, speaking of planting and rain, tractors and taxes† (6). Besides, the lottery is used as a tool to sustain orthodoxy, but it brutally punishes individuals. Jackson Bill knows that lottery is not a fortune to his family. Still, he never tries to act against this inhuman custom. As the community members are supposed to follow the orthodoxy, one cannot expect the protagonist (say, Jackson Bill) to act against the same. S.T. Joshi opines that, â€Å"Certainly there is nothing supernatural about â€Å"The Lottery† (1948), whose impact rests on the very possibility of its occurrence† (13). From a different angle of view, the author makes use of the helpless cha racters to expose the inhuman aspects of orthodoxy. On the other side, the villagers still believe that sacrifice can result in fortune (say, good harvest). The author makes use of Tessie as the tool to proclaim the need to discard orthodoxy. Tessie is portrayed as the victim of orthodoxy, but she does not try to subdue to the same. Instead, she tries to express her views on forced human sacrifice. Still, this does not change the villagers’ attitude because their belief is blind. They never try to go beyond orthodoxy because their community never allows it. James Hugh Toner makes clear that, â€Å"By custom, others in the family join in to kill the lottery â€Å"winner†Ã¢â‚¬  (9). Bill knows that he cannot save his wife. Still, he does not try to save his wife. On the other side, Tessie tries to educate the villagers on their inhuman orthodoxy, but for no use. So, the author expects that Tessie’s fate will create awareness among the mass on the need to discard inhuman rituals

Legal Critique#1 - Assignment Example aking into account federal funds, which the University received for educational necessities, the deaf student was supposed to use the services of sign-language interpreter provided by the University. However, the University refused to satisfy the student’s requirement and, therefore, displayed discriminatory attitude to a person with physical deviation (P#3, C#1, L#11-13). The plaintiff demanded the United States District Court for the Western District of Texas to provide declaratory relief and oblige the respondent to ensure the services of interpreter. The Federal Court granted preliminary injunction, which forced the University to satisfy the plaintiff’s complaint. This decision was made based on the assumption that Walter Camenisch would prevail on merits. Simultaneously, preliminary injunction took place along with the requirement for the plaintiff to post a security bond of $3,000.00 (1981 P#3, C#1, L#31-35). However, the case was forwarded to the Court of Appeals claiming for its mootness caused with the graduation of a student. The Court of Appeals confirmed the preliminary injunction. The University received certiorari (1981, P#3, C#2, L#8-12). But the Supreme Court raised the issue regarding not the question about who should pay for the interpreter, which the Court of Appeals correctly decided to be viewed in a trial on the merits, but whether the District Court exceeded the authority and violated its discretion by granting preliminary relief (1981 P#1, C#2, L#6-7). Considering the chance that the absence of injunction would harm Walter Camenisch, the District Court granted preliminary injunction based on a judgment on the merits. Preliminary evaluation of the merits showed prevalence of the student. In addition, the court ordered the complainant to ensure security bond for protecting the defendant. The University implemented the court’s decision and the student graduated meanwhile the Court of Appeals rejected the mootness of the case stating that

Understanding the concept of Separation of Church and the State from a Historical Perspective Essay Example for Free

Understanding the concept of Separation of Church and the State from a Historical Perspective Essay Controversy, disputes, and misconceptions surround the public’s understanding of the concept of the separation of the church and the state.   Most people think that this concept is a modern invention of man which started in the 18th Century.   They say that Thomas Jefferson is â€Å"the primary architect of the American tradition of separation of church and state.† (Thomas Jefferson and the Separation of Church and the State† 1) It must however be stressed that the concept of separation of church and the state had its origin in the Bible.    The New Testament says â€Å"render to Caesar the things that are Caesars and to God the things that are Gods.   During the Medieval era, it was believed that God metaphorically handed down two swords as a symbol of authority: the spiritual sword and the temporal sword. The spiritual sword was bestowed upon the Pope while the temporal sword was entrusted to the civil magistrates such as the emperors, kings and dukes.   It was believed that the civil law was subordinated to the ecclesiastical rule and the purpose of the separation is to protect the church’s eminence against the intrusions of the state.   Thus, Pope Boniface VIII in 1302 states that: â€Å"We are taught by the words of the Gospel that in this Church and in its power there are two swords, a spiritual, to wit, and a temporal. [B]oth are in the power of the Church, namely the spiritual and [temporal] swords; the one, indeed, to be wielded for the Church, the other by the Church; the former by the priest, the latter by the hand of kings and knights, but at the will and sufferance of the priest. For it is necessary that one sword should be under another and that the temporal authority should be subjected to the spiritual† (John Whitte Jr. 3)      During the 17th Century, however, the public had become witnesses to the religious conflict and incessant bickering between different religions, or more particularly, Protestants and Catholics.   Because of this ‘War of Religion’ a crisis of authority had developed.   The public did not know what to believe and whom to believe anymore. As a result, Locke advocated the principle of Separation of the Church and the State which will later on be considered as ‘the source for the founding principles of the United States’ (Chuck Braman 1).   Locke came to the conclusion that the prevailing conflict was due to the religious dogmatism which was imposed and adopted by the State.   He argued that the proper response on this problem was not the imposition of a single religion to be dictated by the State and the suppression of other religions also by the State. Locke proposed that the State should confine itself to civil concerns and leave the matters of religion to the church.   He advocated religious neutrality on the part of the state and vice versa.   He argued that the state’s function should be confined to the protection of life, liberty and property.   This function is especially important when man tries to go against the State of Nature, which is a state of equality between individuals and tries to impose themselves against the other. Locke also proposed that the church must make itself separate and distinct from the state.   In his â€Å"Letter Concerning Toleration†, Locke thought that the church is simply a voluntary society of men joining themselves together of their own accord in order to the public worshipping of God in such manner as they judge acceptable to Him, and effectual for the salvation of their souls.† (John Whitte Jr 4) At present, the concept of separation of church and the state is based on the principle of respect between the two powerful institutions.   The separation is not one of hostility but an understanding that their union will only lead to the destruction of the state and the degrading of the church.   Separation of the Church and the State is now guaranteed under the Free Exercise Clause and the Establishment Clause. The Free Exercise clause renders unconstitutional any act of the government that prohibits a particular religion.   The Establishment Clause, on the other hand, protects against any act of the state that promotes a particular religion.   The religious freedom has for its purpose â€Å"the protection of liberty of conscience of the public, freedom of religious expression, and religious equality.† (John Whitte Jr., 12) Conclusion Our present understanding of the Separation of Church and the State has completely evolved. If in the past, the church advocated the principle of separation because of the competing interest between the two powerful institutions.   Nowadays, the principle of separation is essentially based on respect and it has been extended to include protection of the faithful. Thus, the concept of separation of church and state has been expanded to include the prohibition against the state allocating government funds for the establishment or support a particular religion, the prohibition against requiring the teaching of a particular religion in schools or imposing religious tests in the exercise of civil and political rights and the prohibition against religious officials utilizing on government sponsorships or funding for their religious exercises   Cited Works Braman, Chuck.   The Political Philosophy of John Locke and Its Influence on the Founding   Ã‚  Ã‚  Ã‚   Fathers and the Political Documents They Created. 1996. 13 June 2008.     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   http://www.chuckbraman.com/Writing/WritingFilesPhilosophy/locke.htm. â€Å"Thomas Jefferson and the Separation of Church and State.† 13 June 2008.     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   http://candst.tripod.com/tnppage/qjeffson.htm Whitte, John Jr.   Facts and fictions about the history of separation of church and state.   Journal   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   of Church and State. 1 January 2006.   12 June 2008.

Cooperative Vehicle Safety System for VANETs

Cooperative Vehicle Safety System for VANETs COOPERATIVE VEHICLE SAFETY SYSTEM FOR VEHICULAR AD-HOC NETWORKS T. Sujitha, Final year M.E(CSE), ABSTRACT Vehicular ad hoc networks (VANETs) are a one form of wireless networks used for vehicles communication among themselves on roads. The conventional routing protocols are suitable for mobile ad hoc networks (MANETs). But it’s poorly in VANETs. As communication links break often happen in VANETs compare than in MANETs, the reliable routing is more difficult in the VANET. Research work has been done to the routing reliability of VANETs on highways. In this paper, we use the cooperative vehicle safety system for VANETs. The cooperative vehicle safety system helps to capture the future positions of the vehicles and determines the reliable routes preemptively. This paper is the first to propose a cooperative vehicle safety system for VANETs gives quality-of-service (QoS) support in the routing process. A new mechanism is developed to find the most reliable route in the VANET from the source vehicle to the destination vehicle. Through the simulation results, that the proposed scheme s ignificantly give good result compare than other literature survey. Keywords- vehicular ad hoc network (VANET),DSRC, IEEE 802.11,sensor,OBU,RSU. 1.INTRODUCTION Every day, a most of people die, and many people are injured in traffic accidents around the world. The desire to improve road safety information among vehicles to prevent accidents and improve road safety was the main motivation behind the development of vehicular ad hoc networks (VANETs). VANETs are a promising technology to enable communications among vehicles on roads. They are a special form of mobile ad hoc networks (MANETs) that provide vehicle-to-vehicle communications. It is assumed that each vehicle is equipped with a wireless communication facility to provide ad hoc network connectivity. VANETs tend to operate without an infrastructure, each vehicle in the network can send, receive, and relay messages to other vehicles in the network. Figure 1.1 Structure of Vanet Ad-hoc Networks This way, vehicles can exchange real-time information, and drivers can be informed about road traffic conditions and other travel-related information. The most challenging issue is potentially the high mobility and the frequent changes of the network topology. In VANETs, the network topology could vary when the vehicles change their velocities and/or lanes. These changes depend on the drivers and road situations and are normally not scheduled in advance. Embedded wireless devices are the main components of evolving cooperative active safety systems for vehicles. These systems, which rely on communication between vehicles, deliver warning messages to drivers and may even directly take control of the vehicle to perform evasive maneuvers. The cyber aspects of such applications, including communication and detection of vehicle information are tightly coupled with physical dynamics of vehicles and drivers behavior. Recent research on such cooperative vehicle safety (CVSS) systems has shown that significant performance improvement is possible by coupling the design of the components of the systems that are related to vehicle dynamics with the cyber components that are responsible for tracking other cars and detecting threats. The types of possible actions and warnings in vehicle safety systems range from low-latency collision avoidance or warning systems to moderate-latency system that provide heads up information about possible dangers in the non immediate path of the vehicle. The main differences of these systems are the sources and means of information dissemination and acquisition. In active safety systems, vehicles are required to be continuously aware of their neighborhood of few hundred meters and monitor possible emergency information. This task can be achieved by frequent real time communication between vehicles over dedicated short range communication (DSRC) channel. In addition to inter-vehicle communication; roadside devices may also assist vehicles in learning about their environment by delivering traffic signal or pedestrian related information at intersections. The main requirement of these active safety systems is the possibility of delivering real-time acquired information to and between vehicles at latencies of lower than few hundred milliseconds. Prototypes of such systems are being developed by many automotive manufacturers. 2. EXISTING SYSTEM In DSRC based safety systems, the cyber components are selected so that they meet the requirements of active safety. Nevertheless, the existing designs fall short of supporting a full-fledged CVSS in which a large number of vehicles communicate and cooperate with each other. The main reason behind the issues with the current designs is the level of separation in the design of different components. Later in this paper we describe methods to achieve better performance by further cooperation of the physical and cyber sub-components. In the next subsection we describe existing active safety CVSS systems and their designs. Figure 1.2 Communication in VANET systems. The traditional design of the CVS system, based on the structure depicted, is a straightforward design following the recommendations of an early report by vehicle safety communication consortium (VSCC). According to this report, it is suggested that vehicles should transmit tracking messages every 100ms, to a distance of at least 150m (avg. 250m). Therefore, the message generation module in becomes a periodic process that outputs a sample of the current state of the vehicle in a message every 100msec. The DSRC radio power is set to reach the suggested distance. Given the issues of the above design in crowded networks, several enhancements have recently been proposed to improve the performance of CVS systems beyond the early solutions set forth by VSCC. One such method is the work in [22] that proposes to fairly allocate transmission power across all cars in a max-min fashion; this method helps reduce the load at every point of a formulated 1-D highway and thus reserves bandwidth for emergency messages with higher priorities. This method assumes a predefined maximum load as the target. In another work, a message dispatcher is proposed to reduce required data rate by removing duplicate elements, here, the idea is that many applications require the same data elements from other vehicles. The message dispatcher at the sender side will group data elements from application layer (i.e., the source) and decides how frequently each data element should be broadcast. The above methods focus on the computing module, as defined in this section, and try to improve its performance through observing the behavior of the application, or by incorporating limited physical process information in the design of the computing module. While the above improvements do enhance the performance of CVS systems, these designs do not consider the mutual effects of computation, communication and physical processes on each other. In this, try to identify such mutual effects and propose a design that uses the knowledge of the tight coupling of cyber and physical processes to the benefit of a CVSS system. DESTINATION SEQUENCED DISTANCE VECTOR (DSDV) DSDV is a proactive protocol that maintains route to all the destinations before requirement of the route. Each node maintains a routing table which contains next hop, cost metric towards each destination and a sequence number that is created by the destination itself. This table is exchanged by each node to update route information. A node transmits routing table periodically or when significant new information is available about some route. Whenever a node wants to send packet, it uses the routing table stored locally. For each destination, a node knows which of its neighbor leads to the shortest path to the destination. DSDV is an efficient protocol for route discovery. Whenever a route to a new destination is required, it already exists at the source. Hence, latency for route discovery is very low. DSDV also guarantees loop-free paths. 3. PROPOSED SYSTEM Cooperative message authentication protocol, which augments the basic short group signature protocol by mitigating the computation overhead in the regular broadcast phase. According to, the verification time for short group signature is 11ms with a 3 GHz Pentium IV system. In a typical public safety application, each vehicle broadcasts safety messages every 300 ms, which implies that each vehicle can at most process messages from other vehicles in a stable system. However, according to the measurement, there may exist as many as 87 vehicles broadcasting messages within the 300m communication range of a receiving vehicle, far exceeding its processing capability. Therefore, we propose a cooperative message authentication protocol to fill the gap between the workload and the processing capability. 3.1 PROTOCOL IMPLEMENTATION RSUs broadcast I-public keys, G-public keys of themselves and their neighbor RSUs with certificates and identities of revoked RSUs in their neighborhoods regularly. Authorities employ benign RSUs around compromised RSUs to implement revocation by regular broadcasting those compromised RSUs’ identities. When a vehicle detects the hello message, it starts registration by sending its I-public key and the certificate to the RSU if the RSU is not revoked. Normally, a public key should not be encrypted. However, in our system model, each vehicle’s I-public key is unique, so it is also an identifier of the vehicle. We encrypt it to protect vehicle’s privacy. The RSU sends the hash value of the G-private key which plans to be assigned to the vehicle and the signature of the hash value, vehicle’s I-public key and RSU’s I-public key to the vehicle. RSU’s I-public key is also unique. The vehicle can identify the RSU’s legitimacy after it verifies this message because the RSU uses its I-private key in the message. The vehicle encrypts its Npri and the timestamp by using authorities’ public key. Then, it sends the encryption data with the timestamp and the signature of corresponding information, message 4, to the RSU. The encryption of its Npri and the timestamp is a commitment. It can be useed to detect illegitimate users later. Meanwhile, the signature signed by the vehicle binds vehicle’s information and the assigned G-private key. Then, the RSU cannot re-map them because the RSU does not have vehicle’s I-private key. The RSU sends the G-private key to the vehicle. The vehicle finishes registration procedure after it gets a valid G-private key. Then, the RSU stores the information, as in the local database. The signature in the fifth item is the signature that the RSU receives in message. If authorities need the information of a vehicle when there is a dispute, the RSU has to send the vehicle’s corresponding information to authorities. 3.2 PERFORMANCE EVALUATION The performance of the proposed algorithm is evaluated through network simulator version 2. A cooperative message authentication protocol(CMAP) is presented to alleviate vehicles computation burden. In the protocol, because vehicles share their verification results with each other in a cooperative way, the number of safety messages that each vehicle needs to verify will be reduced greatly. A new research issue of the protocol is how to select verifiers in the city road scenario. Thus, we propose three verifiers selection algorithms, n-nearest method, most-even distributed method and the compound method for the CMAP. Performance metrics are utilized in the simulations for performance comparison. Packet arrival rate The ratio of the number of received data packets to the number of total data packets sent by the source. Energy consumption The energy consumption for the entire network includes transmission energy consumption for both the data and control packets. Average end-to-end delay The average time elapsed for delivering a data packet within a successful transmission. Control overhead The average number of transmitted control bytes per second, including both the data packet header and the control packets. Collision rate The average Collision rate for the entire data transmission from source to destination is much controlled and reduced when compared to the existing protocol. 4. ELLIPTIC CURVE DIGITAL SIGNATURE ALGORITHM ECDSA is Elliptic Curve Cryptosystem (ECC)-based implementation of the commonly used digital signature algorithm. ECC provides the same security level as the other discrete logarithm approaches, while the size of the required ECC credentials is much smaller than that of the discrete logarithm systems. The WAVE security service adopt ECDSA-based message authentication for vehicular communications. Two standard elliptic curves namely P-224 and P-256 have been suggested for general purpose message authentications, and certificate authentications in VANETs. A VANET entity is required to transmit periodic safety messages containing its current coordinates, speed, acceleration etc. to the neighboring devices. The typical interval for safety message broadcasts ranges from 100 ms to 300 ms. An authentication scheme has to be incorporated in order to provide reliability and trust for the delivered safety information. Received messages are verified by the receiving entity to ensure the message integrity, and authenticity of sender’s identity. Unfortunately signature verification incurs a cryptographic processing delay at the verifier’s end. Although the verification delay for ECDSA is in the order of milliseconds, with hundreds of vehicles in a dense traffic scenario, an OBU would receive an enormous amount of periodic messages per unit time causing a bottleneck to the authentication process at the receiver end. If OBUs are configured to broadcast their periodic messages every 100 ms, under a heavy traffic scenario, many of the safety messages would either be discarded due to the constrained buffer size of the verification process, or accepted without any verification. Therefore in busy traffic hours, a receiver of vehicular messages would either risk a fatal road-traffic consequence, or it would reject a significant portion of received messages without authenticating when its maximum verification capacity is reached. The current WAVE standards do not include an efficient anonymous authentication scheme for vehicular messages, or even an intelligent authentication strategy which can efficiently verify from a massive number of vehicular safety/application messages. 5. CONCLUSION The proposed protocol designed an identity-based anonymous user-authentication scheme and a cross-layer verification approach for WAVE-enabled VANET’s safety messages. A variation of the conventional ECDSA approach is used with the identity-based signature approach where the common geographical area information of signing vehicles is taken as the signer’s identity. This exempts a vehicle from the mandatory inclusion of a trusted third-party certificate with each broadcast message in a VANET while a user is still identifiable by the trusted third-party up on a dispute. A cross-layer message verification scheme verifies the received messages based on their MAC traffic class and traffic intensity. This ensures that under the rush hour congestion or traffic accident most important messages will not be missed by the verifier. Security analysis and performance evaluation justify our authentication and verification approach for WAVE-enabled vehicular communications. REFERENCES [1] C. E. Perkins and E. M.
