The purposes of this study are to understand and compare: the distributions of the particulate and dissolved 210Po and 210Pb in the northern South China Sea and in the east and west sides of the Luzon Strait; the associated biogeochemical processes, including their mechanisms and rates involved in the area; and the disequilibrium between 226Ra and the 210Pb as observed in profiles. Seawater samples were collected from three stations in the northern South China Sea (station I, J, and F) and one station to the east of the Luzon Strait (station S5) using a Rosette sampling system during three Ocean Researcher I cruises (ORI-688 in July, 2003, ORI-707 in February, 2004, and ORI-734 in October, 2004). The dissolved 210Pb in surface water generally displays higher activities (around 14-28 dpm/100kg) relative to deep water, reflecting atmospheric input. The dissolved 210Pb profile as seen at station F displays a maximum of 26 dpm/100kg at 200 m and lower values at about 10 dpm/100kg below 1500 m. Highest value at 28 dpm/100kg was observed at S5 surface water. It is probably due to being on the path of the Kuroshio which has accumulated atmospheric 210Pb continually from the northern Equatorial Current on its way. The mean residence time with respect to particle scavenging is about 0.62 years for total 210Po within a 50 m mixed layer, and ranges between 0.34 to 1.13 years for total 210Pb in the mixed layer. 210Po is deficient relative to 210Pb in most profiles, suggesting that 210Po is more readily scavenged. The mean scavenging residence time is about 87 years for total 210Pb in the deep water at station F, and 60 years at station J. This residence time is longer than that in both the Pacific and East China Sea deep waters, i.e. a lower scavenging rate in the South China Sea. As the upwelling rate is much higher in the South China Sea than in the Pacific, it may effectively reduce the sinking rate of the sinking particulates, resulting in higher 210Pb residence time in the water columns of the South China Sea.

Several cruises of current measurements along various cross-Taiwan Strait transects were conducted by using shipboard Acoustic Doppler Current Profiler (ADCP) during 2001-2003. The main purpose of these experiments is to obtain seasonal variations of flow structures and volume transport in the central and southern regions of the Taiwan Strait. In each cruise the semidiurnal tidal currents were eliminated from the ADCP currents by two different methods, i.e., the phase averaging method and the TSNOW calculation. The subtidal current in the Taiwan Strait generally flows in the parallel-strait direction. In summer when the southwest monsoon prevails, the water in the strait originates from the South China Sea (SCS) or the Kuroshio. This northward-flowing water is divided into two parts by the archipelago of Penghu; the majority keeps flowing northward along the Penghu Channel (PHC), the minority flows northwestward around the Penghu Island. The flows in the surface layer of the PHC reach a maximum speed of 60 cm/s or greater. In winter, strong NE winds push the fresh and cold China Coastal water southward, along the western part of the Taiwan Strait. The SCS or Kuroshio water still flows northward on the eastern part of the strait. The maximum northward current still occurs in the PHC and is around 20 cm/s or less in the winter. Our results from the phase averaging method of all six cruises indicate that the net transports along the Taiwan Strait are all flowing northward, with a maximum value of about 2.5 Sv in summer (August 2001) and a minimum value of about 0.5 Sv in winter (March 2003). The standard deviation of the volume transport is 0.3 Sv. Due to its greater depths and strong currents, the volume transport in the PHC amounts to approximately 75% of the total transport of the Taiwan Strait. Based on the phase averaging results, the transport is related to the along-strait wind by a simple regression: , the sign convention is positive for southwesterly wind and transport.

In a broad way, the main intention of this study is an attempt to analyze the changes the diplomatic competition between China and Taiwan in Latin America has brought to all the involved parties. How this competition have concentrated in just a few countries serving as Taiwan last stand hold against Chinese attempts to isolate it in the international community during the last three decades. The aim is to understand the whole evolution and dynamics of this great Asian issue elucidated in Latin America, and the way both China and Taiwan have behave to attract the favor of those small Latin American countries while those Latin American countries have also came to profit from this situation. Both, China and Taiwan have an almost symbiotic relationship with Latin America, relationship to become more and more important if current geopolitical and economic conditions were to continue. One side, Both China and Taiwan demand a great amount of Latin American natural resources to fuel their global industry. On the other side, Latin America demands more and more of the finished goods produced in China and Taiwan. The main research question the author will attempt to solve here is: ¡§Why are Latin American states shifting or considering shifting to China?¡¨ complementary questions intended to shed some light on the author¡¦s original assumptions are that Chinese economic growth is not the only explanation for Latin America¡¦s support of China. These questions are as follow: ¡§Does Latin American States perceive China as a threat? Has US double standard contributed to Taiwan losing its Latin American partners? Has Taiwanese implementation of Dollar diplomacy methods in some Latin American states something to do with its losing of supporters? A throughout analysis of both, the Chinese economic and geopolitical reach as well as Latin American¡¦s own search for economic, political and ideological independence from US are the main explanatory for the changes observed in this triangular relationship. Nevertheless, a series of unorthodox foreign policy methods such as ¡¥Dollar Diplomacy¡¦ conditioned foreign aid, have also contributed to these changes.

Climate is emerging as a primary determinant of marine survival and migratory behaviour for Pacific salmon. For example, a regime shift in the mid-1990s was correlated to a major change in the migratory behaviour of coho salmon (Oncorhynchus kisutch) in the Strait of Georgia, BC. The details of this new behaviour pattern remain relatively unknown. Furthermore, many coho stocks have been declining during the past three decades. Mitigative strategies –such as hatchery programs— have done little to reverse the trend, and little is known about how hatchery fish are affecting wild populations. The objective of this dissertation was to identify key mortality areas and provide the first look at the migratory behaviour of juvenile wild and hatchery coho in southwestern British Columbia using new telemetry technologies. As coho pre-smolts are relatively small compared with other salmonid species that are typically studied using acoustic telemetry, the identification of the appropriate sizes of fish and tags to use was critical. The first study tested the effects of surgically implanting the three smallest sizes of acoustic tags available on the growth, survival, performance and condition of coho pre-smolts. The first of three field studies to follow investigated the early migratory behaviour and survival of an endangered coho population. The second field study examined differences in physiology, survival and migratory behaviour between wild and hatchery-reared coho smolts. Finally, the third study analysed the altered marine migratory behaviour of juvenile coho in the Strait of Georgia. This dissertation provides the first evidence of high freshwater mortality rates in the endangered coho population, which has implications for the management and conservation of this and other at-risk stocks. I found differences in migratory behaviour and physiology between wild and hatchery-reared coho, suggesting that mitigative strategies need further evaluation. Finally, the timing of the anomalous coho migration out of the Strait of Georgia confirmed that population changes in the strait are a consequence of ecosystem-related impacts. These findings demonstrate how new technologies could be used to fill major information gaps and improve the management and conservation of Pacific salmon.

Research Doctorate - Doctor of Philosophy (PhD) / After decades of discrimination and deprivation, Australia’s Aboriginal and Torres Strait Islander population faces social circumstances and health status which resemble that of a third world population group. With a wide range of health risk factors and morbidities among this population, a logical place to begin tackling the health problems is at the beginning of life. With increasing recognition of the influence of the intrauterine environment upon health, not only during infancy but into adulthood, improving health during pregnancy offers substantial benefit for present and future generations. The poor health of Aboriginal and Torres Strait Islander Australians is deeply ingrained in social deprivation, poor mental well-being, and an array of modifiable risk factors. Smoking is one risk factor at the centre of this complex web. Smoking is often accompanied by, or used as relief in, stressful situations associated with socioeconomic status, mental health, illness, and other addictions. In order to determine the most appropriate way to tackle the smoking issue among Aboriginal and Torres Strait Islander women, a series of studies were conducted. Initial literature reviews found limited evidence derived from methodologically rigorous studies in mainstream populations, and even less evidence for Aboriginal and Torres Strait Islander, or other Indigenous groups. Exploration of the knowledge and attitudes of these women in relation to antenatal smoking was conducted to identify the most appropriate targets for intervention. The findings from extensive background studies were drawn upon to design an intervention which aimed to be culturally appropriate for Aboriginal and Torres Strait Islander women, providing intensive support to assist these women to quit smoking during their pregnancy. Pilot data from the resulting intervention is presented in Chapter 8 of this Thesis. The social network among Aboriginal and Torres Strait Islander communities appears to play a central role in the behaviour of individuals. With an array of risk factors and influences found not only in the individuals surrounding women, but in their socioeconomic circumstances and overall environment, it may be that the most important approach for achieving health and behaviour change among this population is the mobilisation of social support and efforts to intervene with multiple elements of that environment.
