Microbiological investigations of the Canadian tundra

Microbial communities were analyzed at 17 sites visited during the expedition Tundra Northwest 1999 (TNW-99) by microscopic analyses (epifluorescence microscopy and image analyses). The data were used to describe the communities of bacteria, fungi and algae in detail by number, biovolume and biomass. Great variability was found, which could be related to organic matter content of soils and features of vegetation patterns. The amounts (numbers and abundance) of organisms and data on microbial biomass are discussed in relation to other polar environments of the Northern and Southern Hemispheres.

(Table 1) Age, fork length, tissue d15N and d13C and mercury content of arctic char (Salvelinus alpinus) across the Canadian Arctic

Among-lake variation in mercury (Hg) concentrations in landlocked Arctic char was examined in 27 char populations from remote lakes across the Canadian Arctic. A total of 520 landlocked Arctic char were collected from 27 lakes, as well as sediments and surface water from a subset of lakes in 1999, 2002, and 2005 to 2007. Size, length, age, and trophic position (d15N) of individual char were determined and relationships with total Hg (THg) concentrations investigated, to identify a common covariate for adjustment using analysis of covariance (ANCOVA). A subset of 216 char from 24 populations was used for spatial comparison, after length-adjustment. The influence of trophic position and food web length and abiotic characteristics such as location, geomorphology, lake area, catchment area, catchment-to-lake area ratio of the lakes on adjusted THg concentrations in char muscle tissue were then evaluated. Arctic char from Amituk Lake (Cornwallis Island) had the highest Hg concentrations (1.31 µg/g wet wt), while Tessisoak Lake (Labrador, 0.07 µg/g wet wt) had the lowest. Concentrations of THg were positively correlated with size, d15N, and age, respectively, in 88,71, and 58% of 24 char populations. Length and d15N were correlated in 67% of 24 char populations. Food chain length did not explain the differences in length-adjusted THg concentrations in char. No relationships between adjusted THg concentrations in char and latitude or longitude were found, however, THg concentrations in char showed a positive correlation with catchment-to-lake area ratio. Furthermore, we conclude that inputs from the surrounding environment may influence THg concentrations, and will ultimately affect THg concentrations in char as a result of predicted climate-driven changes that may occur in Arctic lake watersheds.

Evolution in the Concept of Development: How Has The World Bank's Legal Assistance Extended its Reach?

The World Bank's legal and judicial reforms programs have expanded considerably since it began to address the issue of governance in the early 1990s. Initially the Bank focused on legal reforms for inducing private investment. Currently, its legal assistance extends to include the criminal justice sector. Such activities cannot be directly construed from its Articles of Agreement. This paper will discuss how the Bank interpreted its Articles in order to ligitimize its expanding activities. The Bank has manoeuvred itself into the criminal justice sector by skillfully changing its concept of development without deviating from its mandate. The change can be described as an 'evolution' which has allowed the Bank to identify any area as target for its development assistance.

The Central Bank and bank credits in the Philippines : a survey on effectiveness of monetary policy and its measures

In the post-Asian crisis period, bank loans to the manufacturing sector have shown a slow recovery in the affected countries, unexceptionally in the Philippines. This paper provides a literacy survey on the effectiveness of the Central Bank’s monetary policy and the responsiveness of the financial market, and discusses on the future works necessary to better understand the monetary policy effectiveness in the Philippines. As the survey shows, most previous works focus on the correlation between the short-term policy rates and during the period of monetary tightening and relatively less interest in quantitative effectiveness. Future tasks would shed lights on (1) the asset side – other than loan outstanding – of banks to analyze their behavior/preference in structuring portfolios, and (2) the quantitative impacts during the monetary easing period.

Constructing an Indigenous Model of the Self to Address Cultural and Mental Health Issues in the Canadian Subarctic

Since the last decades, academic research has paid much attention to the phenomenon of revitalizing indigenous cultures and, more precisely, the use of traditional indigenous healing methods both to deal with individuals' mental health problems and with broader cultural issues. The re-evaluation of traditional indigenous healing practices as a mode of psychotherapeutic treatment has been perhaps one of the most interesting sociocultural processes in the postmodern era. In this regard, incorporating indigenous forms of healing in a contemporary framework of indigenous mental health treatment should be interpreted not simply as an alternative therapeutic response to the clinical context of Western psychiatry, but also constitutes a political response on the part of ethno-cultural groups that have been stereotyped as socially inferior and culturally backward. As a result, a postmodern form of "traditional healing" developed with various forms of knowledge, rites and the social uses of medicinal plants, has been set in motion on many Canadian indigenous reserves over the last two decades.
