The utility of sedimentary diatoms as a measure of historical lake ph

As a result of increased acid precipitation, the pH of a large number of Canadian Shield lakes has been falling. Prior to this study there was no documentation available to explain the history of lake acidification for the Algoma area lakes. In order to obtain this information the diatom inferred pH technique was developed in this study. During two field seasons, July 1981 and July 1982, short sediment cores (circa 25-30 cm) were collected from 28 study lakes located north of Lake Superior, District Algoma, Ontario. The surface sediment diatoms (0-1 cm) from each of these lakes were carefully identified, enumerated, and classified in terms of their pH indicator status. The surface sediment diatom analysis indicated that lake pH is one of the most important factors affecting the species composition and relative abundance of diatom populations. Thus diatom assemblages can be sensitive indicators of lake acidification. When Nygaard's index alpha was plotted against observed lake pH, a statistically significant relationship resulted (r=-0.89; p=

The Midnight express phenomenon : a historical materialist approach to the reception of the film Midnight express /

This thesis examines the Midnight Express phenomenon focusing on the film's reception by audiences in Europe, North America, and Turkey between 1978-2003. Using and enhancing the "historical materialist approach" to film reception developed by Janet Staiger, the thesis considers the historical determinants of the film's nationally and culturally differential readings in different periods and of the transformations in those readings. The thesis argues that while Midnight Express was most likely read in the late 1970s as an attempt to reaffirm American social identity by projecting Turks as an instance of the negative Other, there has been an important shift in the reception of the film in the West during the 1990s due to the changes in the discursive contexts in which the film has been circulating. One does not observe any specific reference to Turkish prisons as a part of the issue of human rights violations in Turkey in the initial reception of the film by European and American critics, whereas these issues appear to be important constituents of a particular reception of the film in the West in the present. The thesis explains this shift by pointing to the constitution of a particular discourse on human rights violations in Turkey after 1980, and especially throughout the 1990s, which has become a part of the discursive repertoires of the Western audience. Therefore, the thesis argues that today, Midnight Express functions as a more legitimate political statement about Turkey in the eyes of some Western audiences than it had been in the 1970s. On the other hand, parallel to the increasing desire of Turkey to connect itself to the West, particularly to become a member of the European Union, one observes an immense increase in the belief in and defense against the negative effects of Midnight Express on Turkey's international representation since the 1990s. The historical and current discourses that audiences, both in Turkey and abroad, bring into play suggest that these audiences engage with Midnight Express by assuming or denying not only the subject positions constructed by the film text but also certain history-specific extra-filmic subject positions produced by other social and discursive formations.

A comparative study of the change in diatom inferred ph of a staircase of lakes in the Algoma District, Northern Ontario /

Four staircase lakes occupying a single watershed located in the Algoma District, north of Lake Superior were chosen for this study. I examined the subfossil diatom assemblage in the top twenty centimeters of the surface sediments in each of these four lakes in an attempt to reconstruct their respective past pH history. From these analyses it was possible to test the hypothesis that the rate of change of diatom inferred pH was not significantly different in lakes located one below the other in a single "staircase" within a single watershed system. My results indicated that the four Z lakes had been acid for at least the last century. The water color of the three upper Z lakes (Z1, Z2 and Z3) was brown (>30 Pt Co units). The bottom lake (Z4) was the only clear water lake in the system «5 Pt Co units). This bottom staircase lake had no muskeg development around its shoreline. The alkaliphilous diatoms in the Z watershed system were important in determining the diatom inferred pH of the four Z lakes. The centric diatoms were extremely rare in the clearwater bottom lake (Z4). The ecology of the Eupodiscales is perhaps important in the interpretation of sediment in the more acid environment. Lake Z4 was the only one that had a progressive as well as a significant decrease in its downcore diatom inferred pH since the early 1960's. This lead me to speculate that the humic substances present in the upper three brown water lakes (Z1, Z2 and Z3) were perhaps Important in buffering them against a further decrease in water pH even though they were located within an area which was sensitive to acid precipitation.

Middle Ordovician (Whiterockian-Chazyan) trilobites from the Sunblood Formation, District of Mackenzie

The Middle Ordovician Sunblood Formation in the South Nahanni River area, District of Mackenzie, comprises mainly limestones and dolostones of intertidal and shallow subtidal origin as indicated by the presence of desiccation polygons, fenestral fabric, and oncolites. The study of well preserved, silicified trilobites from low diversity, Bathyurus-dominated, Nearshore Biofacies faunas of Whiterockian and Chazyan age collected in six stratigraphic sections through the Sunblood Formation permits the recognition of three new Whiterockian zones, and two previously established Chazyan zones. The Bathyurus mackenziensis, Bathyurus sunbloodensis, and Bathyurus margareti zones (Whiterockian), together with the Bathyurus nevadensis and Bathyurus granu/osus zones (Chazyan) represent the Nearshore Biofacies components of a dual biostratigraphic scheme that considers both temporal and spatial distribution patterns, and are compositionally distinct from faunas in correlative strata around North America that represent other biofacies. Twenty-six species belonging to eighteen genera are described and illustrated. Ludvigsenella ellipsepyga is established as a new bathyurine genus, in addition to four new species of Bathyurus : Bathyurus mackenziensis, Bathyurus sunbloodensis, Bathyurus margareti and Bathyurus acanthopyga. Other genera present are: Basilicus, Isote/us, ///aenus, Bumastoides, Fail/eana, Phorocepha/a,Ceraurinella, Acanthoparypha, Xystocrania, Cydonocephalus, Ectenonotus, Pseudomera, Encrinuroides, Calyptaulax, Amphilichas and Hemiarges.

Multinational drug corporations, intellectual property rights and the Canadian state : a historical and critical analysis

This study critically analyzes the historical role and influence of multinational drug cotpOrations and multinational corporations in general; the u.s. government and the Canadian state in negotiating the global recognition ofIntellectual Property Rights (IPR) under GATT/NAFTA. This process began in 1969 when the Liberal government, in response to high prices for brand-name drugs amended the Patent Act to introduce compulsory licensing by reducing monopoly protection from 20 to seven years. Although the financial position ofthe multinational drug industry was not affected, it campaigned vigorously to change the 1969 legislation. In 1987, the Patent Act was amended to extend protection to 10 years as a condition for free trade talks with the u.s. Nonetheless, the drug industry was not satisfied and accused Canada of providing a bad example to other nations. Therefore, it continued to campaign for global recognition ofIPR laws under GATT. Following the conclusion of the GATTI Trade-Related aspects of Intellectual Property Rights agreement (TRIPS) in 1991, the multinational drug industry and the American government, to the surprise of many, were still not satisfied and sought to implement harsher conditions under NAFTA. The Progressive Conservative government readily agreed without any objections or consideration for the social consequences. As a result, Bill C-91 was introduced. It abandoned compulsory licenses and was made retroactive from December 21, 1991. It is the contention of this thesis that the economic survival of multinational corporations on a global scale depends on the role and functions of the modem state. Similarly, the existence of the state depends on the ideological-political and socioeconomic assistance it gives to multinational corporations on a national and international scale. This dialectical relation of the state and multinational corporations is explored in our theoretical and historical analysis of their role in public policy.

St. Catharines and District Council of Women fonds

The St. Catharines and District Council of Women was founded in 1918 and elected as its first president, Mary Malcolmson. In 1910 Mrs. Malcolmson founded North America’s first Girl Guide Association in St. Catharines. The aim of the organization was to work for the betterment of conditions pertaining to the family, community and state. The Council is an umbrella group for various women’s organizations in the area and functions at the provincial, national and international levels and is associated with the United Nations. In the early years the National Council brought in the Victorian Order of Nurses (VON) and started the Women’s Canadian Club. The St. Catharines Council initiated Child Welfare Centres in local churches that grew into the Well Baby Clinics. Women were encouraged to take political office and join committees with much success. In 1929, “Shop at Home” exhibition became an annual event highlighting the services of local merchants. Money raised by the Council was donated to local charities and in 1930 the Council assisted the local Armenian community in building the first Armenian Church in Canada. In 1932 the Council started the Maternal Welfare programme in which Mothers’ Meetings were held weekly with various speakers from the Public Health Department. In 1975 to celebrate International Women’s Year and the 1976 Centennial of the City of St. Catharines, the group sponsored the book Women of Action, 1876-1976, written by two of its members, Lily M. Bell and Kathleen E. Bray. Some time after 1976 the name of the organization changed from St. Catharines Local Council of Women to St. Catharines and District Council of Women. Today the organization functions as an advocacy and educational group.
