Noise pollution in the ocean - Research Paper Example Some of the marine life has been adversely affected by the increase in noise pollution in the oceans and their survival has been compromised. Most of the marine life species have evolved over the years to possess very acute hearing abilities which are affected by an increase in the noise under water. Naturally, most of the species in the oceans majorly depend on sound to detect danger and also to hunt for their food. Noise pollution masks the important sounds to the marine life and it also causes stress to the animals. This paper focuses on noise pollution in the ocean and addresses the three main animals that are affected and how humans contribute to the noise pollution in the ocean. The three main animals affected by noise pollution Cephalopods Giant squids are some of the ocean animals that are affected by noise pollution. The squids are injured by the noise and it could even lead to death if they are subjected to certain frequencies of sound for a long time. According to research ers who are set out to find out whether squids can hear, the results of their study showed that the sea animals can hear. Unlike humans, their hearing capability is limited to around 500 Hz. This means that the animals cannot perceive the high frequency sounds from animals like dolphin screeches. Recent study has revealed that Giant squids are affected by sound in the least expected way, which affects their balance. In the research experiment, the squids were placed in tanks and were then exposed to two straight hours sound at low frequency. The findings revealed that the animals suffered great damage to their statocyst tissue which is responsible for balance while navigating in the water. The exposure is traumatizing and the lesions in their statocysts get worse (Coghlan 15). There are many types of squids and they have many relatives in the Cephalopods groups of marine species. The Octopus is also in the group and it is also vulnerable to noise pollution. Octopuses have also been affected in a similar way as the Squids by the low frequency noise in the ocean (Heimbuch Para 8). Squids live in various parts of the sea, some may be found in the deep sea while others may be found at more shallow depths. Noise from the activities on the surface of the sea or in the deep sea during fishing done by humans is transferred very fast across the water and it can reach the animals at all depths. Cephalopods are therefore very vulnerable to trauma and damage from noise pollution that is on the increase in the ocean. Cephalopods like the Humboldt Squid have been one of the most adversely affected marine species by noise pollution in the ocean over the past decade. In 2004, thousands of the squids died and were washed to the coast in Oregon. In 2008, a similar case occurred in the same region (Mulvaney Para 1). At that time, the marine biologists had no idea what was causing the mysterious deaths on such a large number of squids. Biologists undertook a study on four species of squids to determine the damage caused by low frequency noise on the animals. After a short time of exposure to the noise, the biologists observed that the hair in the statocysts of the animals had experienced damages. The nerves in the statocysts later swelled and soon after, holes would form in the statocysts. The findings were very shocking since the sound used was very low in frequency and the biologists were worried that exposure to higher frequencies of noise to the squid would have worse effects on them.

Case of Vasiliy Gorshkov and Alexey Ivano Essay

Case of Vasiliy Gorshkov and Alexey Ivano - Essay Example There are readily available hacker tools that can be used by unskilled people to wreak havoc for financial gain or just for fun. The disturbing reality is that many people are not aware they are actually committing a crime until it is too late. This has been a serious problem for teachers, parents, governments and businesses trying to work hard to protect children and the general public from online threats. The best way to protect people from computer crime is by letting them understand what computer crime is all about. Computer crime can be viewed in three ways. The first one is attacking computers of other people by spreading malicious viruses. The second one is using a computer as a weapon to commit crime like illegal gambling or fraud. The third one is storing information in a computer illegally. Introduction In this case study of Vasiliy Gorshkov and Alexey Ivanov we are going to examine whether the FBI investigative techniques went too far in apprehending the two Russian cyber criminals. In addition to this, we will also investigate how the FBI used the law to apprehend the cyber criminals and whether their actions should stand scrutiny under the current U.S. cyber law. Furthermore, more case studies will be examined and the impact of cybercrime investigations of non-U.S. citizens will be discussed and analyzed. The overview has looked at what computer crime is all about and the definition can summarize computer crime as attacking computers of other people by spreading malicious viruses, using a computer to commit crime, and storing illegal information on a computer. Case study Ivanov a 20 year old computer programmer from Russia flew to Seattle in November 2000 to apply for a job in a company called Invita Security. He was promised a dream job and took with him Vasiliy Gorshkov, a fellow programmer. After their arrival in Seattle airport they were given interviews of hacking other networks which they proved to be very successful. They were later arrested by the FBI. In Washington on October 10, 2001, a jury found Vasiliy of Russia guilty on 20 counts of conspiracy on fraud and computer crimes. The targets of the computer crime include Nara Bank, Speakeasy Network, PayPal, National Bank of Waco, and many other companies. He faced a maximum prison term of five years on each count, and a possible prison sentence of 100 years and a fine of $250,000 on each count, although he was sentenced to three years in prison. Ivanov was also charged with conspiracy, hacking, extortion and computer fraud and was given a prison term of eight months and owes in excess of $800,000. Analysis of case study The Federal Bureau of Investigation in the case study did not follow any International Law in their pursuit of the two cyber criminals however the deceit to get them into America is commendable because it allowed the FBI to exercise the right legal justice system in apprehending them. This was done by using a fictional company called Invita that lured the two Russians and their success in hacking into Invita proved they were guilty of cyber crime. According to the United States law the right way in obtaining evidence is not by deceiving computer criminals into committing a crime rather it should be to catch criminals in the act of committing a crime

Gender and Sexual Studies - Research Paper Example Honestly, sometimes it seems like sexuality is a very complex topic of study in the gender relations. However, married men, for example, are often bombarded on a day-to-day basis by conflicting messages and experiences such as you are handsome, you are not handsome (Beasley 123). Women, on the other hand, experience the same compliments like you are not sexy, and you are sexy. Additional conflicting sexuality messages and exceptions to the women include married couple have the worst sex, sex is for your husband, sex is for you and lastly married couples tend to have the best sex complement. Honestly, it is always good to leave women with a smile on their faces, dismay and confusion on their minds. This is embracing sexuality. In the business interactions, everyday stress and fatigue of the libido-suppressing effects, it becomes necessary for people to leave the whole of this â€Å"sexuality thing† for another day (Brownson 145). Embracing sexuality as an aspect of socializatio n is not bad though it should have some limits. When it comes to sexual pleasure, embracing sexuality encourages the best way possible for the married couple to experience sexual pleasure. Additionally, embracing sexuality in the marriage incidence ensures that the marriage partners cordially respect one another. Even though the embracement of sexuality to some degree seems stacked against every married couple personality, sexologists encourage people not to give up or let go of innately driven sex persuasion and intimacy in their marriages.

History of Television Essay Example for Free

History of Television Essay Television Broadcasting Malaysian television broadcasting was introduced on 28 December 1963. Color television was introduced on 28 December 1978. Full-time color transmissions of grand launched until officially inaugurated on New Years Day 1982. There are currently 8 national free-to-air terrestrial television stations in Malaysia and 2 national pay subscription television stations in Malaysia. Out of eight television channels, four of them are available in Sabah and Sarawak, and the other four are available only in Peninsular Malaysia.Transmissions in Malaysia were black-and-white until 28 December 1978. First stereo audio broadcasting was introduced in 1985 by TV3. Five out of eight channels does not have 24-hour schedule. 24-hour television was introduced in Malaysia between 13 to 16 May 1989 on TV1. The first 24-hour broadcasting in Malaysia was introduced in 2007 by TV2. Local Programming RTM had local programmings in each state until 1984, and those local stations had been replaced by relay of RTM1. RTM1 had 1 hour of local programming between 1984 to 1992. Today, RTM broadcasts the same version nationwide except in Sarawak and Sabah, which still have some local programmings. RTM have plans to re-introduce the local channels after digital switchover. The local channels had the name RTM and state name, for example RTM Pinang for Penang. Each channel had its own schedule and broadcasting hours, and some programs relay from RTM1 and RTM2 (usually news programs and government programs). Between 1984 to 1992, the local programmings was around 5:00pm on RTM1. For the new local channels, the broadcasting hours are currently unknown. Today, RTM still broadcasting radio in local, but television in national.

Accessibility of Centres to the Road Networks: Lagos Island

Accessibility of Centres to the Road Networks: Lagos Island THE ACCESSIBILITY OF CENTRES TO THE ROAD NETWORKS: THE CASE OF LAGOS ISLAND, NIGERIA Mr. A. O. Atubi Prof. P.C Onokala Abstract Proper co-ordination of transport and public facilities provision is vital to any balanced regional development strategy. The central aim of this study therefore was to study the relationship between access to the transport networks and the provision of central facilities in Lagos Island. The results of the analysis of connectivity indices reveal the development of an increasing complex network, although the road network for 1997 remained the same as that of 1986. Using simple regression analysis, it was found that no strong relationship between road, accessibility and occurrence of facilities could be established. Rather population of centres was found to be more significant factor in the distribution of public facilities. Thus, recommendations capable of enhancing equitable transport development include; constructing new roads that will increase accessibility, save time and reduce cost to other centres and relocating some facilities too. Introduction In an urban area, there is a complex mix of land uses and all the major broad groupings of person movements (i.e.) journey to work, official trips, education trips by school children/students, shopping trips, journey made to get home, an miscellaneous journeys) in urban areas are made between them. Thus, while trip are made for a variety of purposes, they are made to and from various land use Onokala. (1995). Oyelegbin (1996), observed that traffic jams keep Lagos motorist on the roads for hours and that many motorists are blaming frequent traffic Jams of numerous deep pot-holes, blocked drainages and poor road network system. While the number of vehicles were increasing the road network infrastructure are not bet increased proportionately and even the existing ones degenerate in quality at increasing rate. The Lagos Island Local Government Area is the single most important local government in Lagos State due to the fact that most government establishments: private parastatals and public buildings are located here. It is essential to appreciate that the purpose of transport is to provide accessibility, or the ability to make a journey for a specific purpose. Transport is not timed for its own sake, but is merely a means to an end. The construction of transport infrastructure influences transport costs by is of a reduction of distances and/or a higher average speed. This will lead to changes in the choice of transport mode, route choice, time of departure (in the case ingested networks) and the generation or attraction of new movements per zone (Bruinsma, et al 1994). For example, within several European countries both the private sectors, as represented by mobile shops, and the public sector for example mobile library, have for many years provided services on-wheels for rural communities. Existing services could in future he coordinated to ensure that each community in turn became the focus of several of these services, so that the hinterland population need make only one journey into the centre to take advantage range of facilities (Brian and Rodney. 1995). Thus, in the U.S.A. accessibility studies in the late 1970’s and 1980’s centres on access to public facilities especially as observed by Lineberry (1977). Mladcnka 78), Mclafferty and Gosh (1982). In Nigeria several studies on accessibility tend to be related to urban centres or urban based activities. However, Onokerhoraye (1976) and Okafor (1982) sought to identify the major factors that influence distribution of post primary schools in Ilorin and lbadan respectively. They attributed the larger catchment areas to urban schools to travel distance to school and to population of urban centres. [Bardi (1982) also investigated the relationship between growth of road network and accessibility of urban centres in Bendel State, while Abumere (1982) tried to establish the nodal structure of Bendel State towns m the foregoing discussions of past studies in Nigeria we observed that the emphasis tends to be either on urban centres (Onokerhorave. 1976), postal services (Oherein, 1 985), banking (Soyode et al. 1975), bus transport services (Ali, 1997) and access to facilities in relation to road network (Atubi, 1998). There is however a need to take a total vie of transport in terms of the various activities for which the users demand mobility (Jansen, 1978). Methodology This research focused primarily on the study of road transport network system in Lagos Island Local Government Area especially as it relates to accessibility of centres Thus, structural characteristics and accessibility of major centres to the road network was considered at three points in time i.e. (1976, 1986 and 1997 periods). In developing the research design, areas that are accessible to the road network and with population of 1,000 and above at each period were taken as activity centres. Population of 1.000 was chosen as cut-off point to enable a substantial number of centres, especially those at the end of routes to appear as nodes especially as the network grows. The choice of nodes was therefore based on population size. Data Analysis and Discussions of Results In order to classify the major centres, data on six areas of central facility provision were collected namely: Medical, educational, market, postal services, banking and administrative headquarters. Data on these chosen facilities were collected both from published sources and through field survey. A list of registered health facilities in the study area by 1997 compiled by the Lagos State Ministry of Health, Alausa. Ikeja: list of primary schools in Lagos Island Local Government Area from the Lagos Island Local Education District Department, and monthly returns of postal facilities from post and Telecommunications (NIPOST) Marina, Lagos were used as the base data to collect the number of these facilities. More comparative data on the number and location of the services are collected from the General Post Office (G.P.O.) Marina. Lagos. The data on the distribution of banks in Lagos Island Local Government Area were collected from Central Bank of Nigeria, Lagos, while data on the distribution of markets were collected from the Department of marketing Lagos Island Local Government Secretariat. City Hall, Lagos. The accessibility of centres to the road network in Lagos Island Government Area was analyzed using the graph theory approach. It is used to handle properties to transportation networks in order to bring out their characteristics and structures. Other major techniques of analysis used include the homogenization of data etc. By 1976, we had 22 out of the 30 major centres directly connected by all season roads. Each direct connection forms a link. As an illustration by 1976, one could only move from race course to Cable Street (Net) before moving to C.M.S. (Old Marina). In this case we have 2 links along Race Course C.M.S. (Old Marina) road. In sum, 23 links or edges were identified by 1976 which connected 22 nodes. By 1986, the network became more complex as more nodes are connected through different routes. However, the same principles are applied. It has been observed that by 1986 the 30 nodes had become connected by 39 links. That means 7 extra centres had entered into the network systems. These are Leventis. C.M.S. New Marina), Force Road. Awolowo Road, Ilubirin, Ebute-Elefun and Anokantamo. By 1997, the network remained the same as that of 1986 but the major difference was the construction of Third Main Land Bridge that links Lagos inland Local Government Area to Lagos Island Local Government Area. This was that since 1986, no major work has been done on the road network in Lagos and Local Government Area, hence the road network remained the same. Although, the indices of connectivity indicate increasing complexity of network between 1976 and 1997, the indices of nodal accessibility, which explain the accessibility of one node to all others in the network, indicate the changing fortunes some centres. It is interesting to note that in terms of overall road distance, the most accessible centres in 1976 were Tinubu, Martins and Balogun, while the least accessible were Race Course. Epetedo and C.M.S. (Old Marina). By 1986, we observed that Odularni had become the most accessible centre, while Tinubu and Nnamdi Azikiwe had become the second and Third most accessible centres in the network. Again, it was noted that Epetedo (Okepopo Marina), Ebute-Elefun, Anokantamo and ldumagbo remained the least accessible centres. Other new centres connected to the network at this state include C.M.S. Maria road), Force Road, Awolowo Road, Ebute-Eletun, Anokantamo and Idumagho. Their entry into the network has the effect of increasing the accessibility for all the nodes. However, by 1997 it was observed that odulami remained the most accessible centre which corresponds with the nodal accessibility by 1986, while Tinubu and Nnamdi Azikiwe remained the second and third most accessible centres in the network which also corresponds with the nodal accessibility by 1986. Again, it was observed that Eptedo (Okepopo Marina), Ebute_Eleflm, Anokautamo and ldumagbo remain the least accessible centres. Also he Tinubu-Nnam di Azikiwe-Odulami-Bamgbose axis seems to have been enjoying high level of accessibility throughout the period. The more nodes are connected the greater the accessibility value for individual nodes. However, the entire network accessibility expands with increasing number of nodes brought into the network. Another observation is that there are some nodes (Awolowo Road, Ilubirin. Force Road, and C.M.S. (New marina Road) that were not connected in earlier times but they acquired quite high accessibility as soon as they were connected. It is observed further that there are some nodes, which declined in accessibility as more links were added. Thus Tinubu, Odulami. Olowogbowo, Balogun and Broad Street among others, declined in accessibility. The construction of Leventis C.M.S. (New Marina Road) meant that a shorter route to cable street (net) from Force Road than through Tinuhu had been created. Other routes constructed prior to 1997, which reduced the position of Tinuhu, include martins Street-ldumota, C.M.S. (Old marina-Odulami and Okepopo. In this analysis. the researchers used the simple regression. A possible relationship between accessibility and human activities has been suggested by Lachene (1965) and Chapman (1979) among others, while Keeble et al (1982) actually established a relationship between accessibility and economic activities among the countries of the E.E.C. within the country. Atuhi (1998) has in Lagos State suggested some relationship between accessibility and public facility index, while Ali (1997) suggested some relationship between accessibility and bus transport services in Enugu. For public facilities however, whose essential quality of their location is that they be as accessible to their users as possible one should expect to find a strong relationship between the two. Policy Implications The strategy of constructing new links to improve accessibility may involve heavier financial investment. Thus, a proper cost-benefit analysis is needed to determine the desirability of such investment. Still another strategy would he to provide those services which centres lack based on extensive surveys of what are available and what are needed. This centre based approach might prove more useful if the people are guided to choose out of their preference. Conclusion It is pertinent to note that the social benefit of constructing a road that increases accessibility saves time and reduces cost goes beyond the financial evaluation. This is because it touches on human value. References Abumere. SI, (1982) The nodal structure of Bendel State Nigeria Geographical Journal, vol. 25. Pp. 173-I 87. Ali, A.N.
