Abstract After the ban against private-owned gas service stations was lifted in 1987, some domestic trading firms took advantage of the special feature of gasoline products as well as Taiwan¡¦s unique oil price structure to import low-quality oil products for blending into gasoline-equivalent products, which would then be sold to independent service station owners mushrooming in accordance with the oil market deregulation. According to the statistics of import/export at Taiwan customs and the comparison between supply and demand of relative industries, it is agreed that an annual total of approximate 400,000 kiloliters of various imported oil products would be blended into gasoline or diesels for sale. Moreover, as Taiwan government has been continuously providing a 14% oil price subsidy against a sluggish fishing industry caused by depleting fishing resources, the fishing fuels in glut, at an estimate of 410, 000 kiloliters a year, would be illegally sold as diesel in domestic gas service stations for higher profits. These practices have not only directly affected tax revenues of local governments, but also infringed upon the legal rights of petroleum refineries, putting the orderliness of petroleum production and sale in jeopardy. In addition, as such illicit practices are usually carried out near makeshift storage tanks with ineligible filling facilities, they have posed great threats to public safety and environment. As it is difficult to detect and thereby root out the underground transactions of such inferior gasoline and diesels, the police that was authorized insufficiently on legal aspects would carry out inspections at key roads and intersections only passively, which has posed but limited intimidation over illegal transactions of unqualified gasoline products. Realizing the facts, this survey takes the historical data on relative factors and market survey figures as basis for calculation and analysis, which is used then to assume the normal demand of gasoline and diesel markets and to establish a conclusive alarming model for flow direction. Besides, it obtains affecting variables such as market segmentation, channel characteristics, customer behaviors, price gap and business environments through interviews and questionnaires, to determine limits on the alarming model and the alarming value. Comparing with the actual consumption of gasoline and diesels, we can then judge if there remains any abnormality concerning the sales volume of gasoline and diesels. If any abnormal sign shown, we can check the alarming model item by item for timely management and control, so as to supervise and check the underground transactions of inferior gasoline and diesels. We also hope that the survey report on ¡§the Alarming Model over the Flow of Inferior Gasoline and Diesels and Its Application¡¨ could provide practical references for the detection and elimination of inferior gasoline and diesels so that the illicit and unsafe practice could be inhibited once and for all.

The distance of sound propagation in water is inversely proportional to the frequency; there for the low frequency noise generated by distance shipping contribute most to the low frequency components of the ocean ambient noise. In order to improve the performance of sonar application, understanding and predication shipping noise is important. In this study, noise data was collected by vertical line array (VLA), in South China Sea of Asian Seas International Acoustics Experiment (ASIEX) in 2001. Due to the limited access to the satellite imagery, and based on the assumption that fishing vessels in South China Sea has similar operational pattern and lighting in recent years, the night time satellite image data was acquired by Defense Meteorological Satellite Program DMSP - Operational Linescan System(DMSP-OLS) of 2005. Linear regression was analyzed between fishing light pixel distribution and low frequency noise level variation, fishing light was expressed in terms of total pixel number and total light intensity, and distance from fishing vessel to VLA was assumed by spherical and cylindrical spread. The results show high correlation between total light intensity and noise level, and cylindrical spreading is better assumption in shallow water on the continental shelf at low frequency. As a conclusion, this study successfully prove that by using the night satellite image, the low frequency fishing vessel noise can be predicted with reasonable accuracy.

Abstract As the environmental consequences of urbanization and climate change become apparent in coastal communities, it has become important to understand how residents of these communities experience and approach their changing environments. This becomes especially significant in places where nature-based livelihoods constitute a major part of the economy. This thesis focuses on the city of Tarpon Springs, located along the Gulf of Mexico in Florida, where sea sponge fishing is an important contributor to the local economy while also being central to place-based tourist and ethnic identities. It seeks to understand how environmental changes in the sea sponge economy will affect the coastal economy of Tarpon Springs. Based on interviews conducted with people closely connected with the sponge fishing economy, including sponge fishers and shops selling sponges, the thesis delves into (i) local perspectives on changing environmental conditions, (ii) how such changes will impact the future of sponge fishing and (iii) the extent to which local governmental support has been sought by sponge fishers and shops. Sponge fishing in Tarpon Springs is connected to its Greek identity so changes in the sponge economy could potentially affect whether tourist experiences which highlight Greek identity linked to sponge fishing continue to be connected to an actual Greek economic presence or reflect nostalgia for a Greek past. The interview responses showed concerns about declining sponge hauls which were connected to more immediate experiences of environmental change and pollution, including red tide events and phosphate runoff. Respondents also reflected on how climate change will exacerbate such environmental issues through rising water temperatures. Respondents viewed Tarpon Springs as a community with a strong Greek identity and sponge shop owners especially seemed to be dependent on links with an active sponge fishing economy to enhance the value of their sponges for tourists. In terms of government support, those involved in the sponge economy had very little interaction with city officials and did not seem keen to enhance such interactions. This thesis thus reveals that the economy of Tarpon Springs continues to be shaped by sponge fishing livelihoods that are directly dependent on nature. However, it seems that concerns related to environmental change remain within the local community and are not being voiced through more public forums, such as through active engagement with local government. The future of Tarpon Springs and its sponge fishing economy therefore remains uncertain, even as local participants in the sponge economy continue to work towards maintaining their unique identity.

Both the use of and jurisdiction over fisheries resources is an important issue for many First Nations in British Columbia. Historically, fish played an important spiritual, social and economic role in numerous Aboriginal societies. These societies had various methods of managing the resource and, although they had the technological capacity to over-exploit the fisheries, they were able to maintain sustainable levels of fish. Following contact with European settlers, Aboriginal fishers were initially able to continue their traditional methods of fishing as well as expand their use of the fisheries through trade with non- Aboriginals. However, with the opening of the canneries on the coast the fisheries grew in economic importance to non-Aboriginal fishers and management of the resource was gradually but systematically taken over by the state, with various ideologies being used to justify the take-over. Aboriginal fishers lost not only their control over management of the resource, but also their ability to use it as extensively as they once had. Over the years, Aboriginal participation in both the food and commercial fisheries has declined although various government-sponsored programs have been initiated to attempt, with only partial success, to remedy this problem. In the meantime, the Department of Fisheries and Oceans has been battling other problems in the commercial fisheries, including over-capitalization of the fleet and depletion of fish stocks. Management of salmon in particular, because it is an anadromous species which travels through several different jurisdictions, has become extremely complex. It is in this context that much litigation over Aboriginal fishing has been launched. Only a few of the issues have been clarified by the judgments which have resulted and certain myths and ideologies have surfaced repeatedly in many of the decisions. It is likely that the recent decisions of the Supreme Court of Canada on Aboriginal commercial and management rights will result in increased complexity and political controversy. However, problems of fisheries management, including the accommodation of Aboriginal interests, is not unique to British Columbia or even Canada. Similar problems have been experienced elsewhere in the world and various types of co-management regimes have been established in various jurisdictions in an attempt to deal with some of these issues and to recognize a greater role for Aboriginal fishers and communities in fisheries management. It is not clear whether, and to what extent, comanagement will be adopted in British Columbia, or what the role of Aboriginal fishers might be in such a regime. Even if co-management is established, it is highly probable that the state's underlying regulatory regime will remain intact. However, co-management may result in increased Aboriginal participation in both the use and management of the resource.
