A History of Change and Reorganization: The Pelagic Longline Fishery in Gouyave, Grenada
This paper traces the history of the pelagic surface longline fishery in Gouyave, Grenada, noting 4 major periods of change from pre-1985 to 2004. Reconstructed from document reviews, newspaper articles, oral history, and key informant interviews 1) the pre-1985 period was the time when the longline was introduced and popularized by the Cubans, 2) the period of institutionalization and technology development (1986-1990) corresponded to the strengthening of institutional arrangements and the initial improvements in technology, 3) the Coastal Fisheries Development Project (CFDP) of 1991-1999 was the period of international donor support and further technology change in longline construction, and finally 4) the 2000-2004 period marked innovation, training and fish quality control for export markets. The main point of the paper is that fisheries management is about the management of change. Fishery managers need to learn to deal, not only with technology change, but also with surprise and variability related to biophysical change (e.g., hurricanes), change in markets, and other external drivers such as international policies. Key considerations for managers to deal successfully with change include: learning from experience, capacity building, and the need to engage cooperatively with fishers and communities, the private sector, and non-governmental organizations
Physiology of Sporeforming Bacteria Associated with Insects: Radiorespirometric Survey of Carbohydrate Metabolism In the 12 Serotypes of \u3ci\u3eBacillus thuringiensis\u3c/i\u3e
Radiorespirometry was used to compare the primary pathways of glucose catabolism in 18 strains of Bacillus thuringiensis representing the 12 established serotypes. Every strain utilizes the Embden-Meyerhof-Pamas pathway almost exclusively; pentose-phosphate pathway participation is minor. The Embden- Meyerhof-Parnas pathway predominates regardless of whether the cells were grown in a minimal medium or one containing yeast extract. The results indicate that the absolute requirement for citrate and related compounds is not a result of defective citrate or glucose transport and metabolism
Canadian Arctic Tide Measurement Techniques and Results
About 10 years ago the Canadian Hydrographic Service recognized the need for a planned approach to completing tide and current surveys of the Canadian Arctic Archipelago in order to meet the requirements of marine shipping and construction industries as well as the needs of environmental studies related to resource development. Therefore, a program of tidal surveys was begun which has resulted in a data base of tidal records covering most of the Archipelago. In this paper the problems faced by tidal surveyors and others working in the harsh Arctic environment are described and the variety of equipment and techniques developed for short, medium and long-term deployments are reported. The tidal characteristics throughout the Archipelago, determined primarily from these surveys, are briefly summarized. It was also recognized that there would be a need for real time tidal data by engineers, surveyors and mariners. Since the existing permanent tide gauges in the Arctic do not have this capability, a project was started in the early 1980’s to develop and construct a new permanent gauging system. The first of these gauges was constructed during the summer of 1985 and is described
Managing sustainable non-profit network organizations
We draw upon a case study conducted within a non-profit network organization to propose five dualities which are central to understanding effective management of non-profit networks. We then examine strategies that address these dualities, based on new approaches to leadership, performance measurement, governance, coaching and creative management of dualities
Characterization of the Plasmidic or Chromosomal cpe Gene and Metabolic Activities in Clostridium perfringens Isolates from Food in San Luis - Argentina
Food poisoning and non-food poisoning illnesses due to C. perfringens (by enterotoxin production) have been associated to chromosomal or plasmidic location of the cpe gene, respectively. Clostridial pathogenicity has been correlated to protease and azoreductase production.The aim of this work was: i) to assess the sanitary-hygienic quality of dehydrated soups (100 samples) consumed in San Luis – Argentina; ii) to verify the presence of C. perfringens in these food products using the "Most Probable Number" method (MPN) and plate-counting methods; iii) to characterise enterotoxigenicity in strain isolates by RPLA; iv) to determine the chromosomal or plasmidic location of the cpe gene in enterotoxigenic strains previously isolated from food in our lab, using PCR; v) to correlate chromosomal cpe and spore heat-resistance; vi) to compare protease activity in cpe+ and cpe– strains; and vii) to compare azoreductase activity in cpe+ and cpe– strains. Twenty-six isolates had a count a 3–43 bacteria g-1 count using MPN; 7.7% exceeded the Argentine Food Code (CAA) limit. All isolates showed protease activity: enterotoxigenic isolates had higher protease activity than non-enterotoxigenic isolates. All isolates showed azoreductase activity: enterotoxigenic isolates had higher activity and shorter reducing times. Enterotoxigenic isolates showed chromosomal location for the gene responsible for the enterotoxin.Fil: Corigliano, Mariana Georgina. Universidad Nacional de San Luis; Argentina.

The Need for Accreditation in Medical Education to be based on Regional and National Health Priorities
In this paper, we argue that it is time to review the relationship between global ideas about the quality of medical education and actual local
need. We suggest that a conversation is needed to rebalance the focus of activity from international to regional, and to take control of
quality and its accreditation within our own contexts
Distribution of mycorrhizal fungi in different soil zone with pyrosequencing approach
Non-Peer ReviewedWe collected 83 soil samples distributed in all five soil types of Saskatchewan, and amplified 18s rDNA as our target DNA segment with primer pairs NS1/NS4 and AMV4.5NF/AMDGR. Sequencing results show that there is rich diversity of AM and other soil fungi in summer season but fungal composition vary among different soil zones and culture management
