The Paraty Artisanal Fishery (southeastern Brazilian Coast): Ethnoecology And Management Of A Social-ecological System (ses)
This study intends to give recommendations to the management of Paraty fishery in Brazil through an interplay of local and scientific knowledge. In particular, the objectives are the following: 1) to describe the Paraty fishery; 2) to compare the fishermen's local ecological knowledge with recorded fish landings and previous studies in Paraty; 3) to combine the data on local fishing and on local/Caiçara livelihoods with the SES (social-ecological systems) Model. The methods include a systematic survey of fishing in Tarituba and Praia Grande, which are located in the northern end and the central part of the Paraty municipality, respectively. For four days each month, systematic data on catches at landing points were collected, as well as macroscopic gonad analysis data for the fishes Centropomus parallelus and C. undecimalis (snook, robalo), Epinephelus marginatus (grouper, garoupa), Scomberomorus cavalla (King mackerel, cavala), and Lutjanus synagris (Lane snapper, vermelho). Spring and summer are important seasons during which some species reproduce, and the integration of fishing periods for some target species could assist in fishing management through the use of closed seasons. Fishermen could obtain complementary earnings from tourism and from the " defeso system" (closed season including a salary payment) to conserve fishing stocks. The SES model facilitates an understanding of the historical context of fishing, its economic importance for local livelihoods, the constraints from conservation measures that affect fishermen, and the management processes that already exist, such as the defeso. If used to integrate fishing with complementary activities (tourism), such a system could improve the responsibility of fishermen regarding the conservation of fish stocks. © 2012 Begossi et al.; licensee BioMed Central Ltd.8Acheson, J., The lobster fiefs: economic and ecological effects of territoriality in the Maine lobster industry (1975) Hum Ecol, 3, pp. 183-187Acheson, J., (2003) Capturing the commons, , New England: University Press of New EnglandMcCay, B.J., Acheson, J.M., (1987) The Question of the Commons: The Culture and Ecology ofCommunal Resources, , Tucson: University of Arizona PressJohannes, R.E., (1981) Words of the lagoon Berkeley, , University of California PressJohannes, R.E., The Renaissance of community-based marine resourcemanagementin Oceania (2002) Annu Rev Ecol Syst, 33, pp. 317-340Huntington, H.P., The local perspective (2011) Nature, 478, p. 183Berkes, F., Fishermen and the " Tragedy of the Commons" (1985) Environ Conserv, 12, pp. 199-206Berkes, F., (1989) Common property-resources, , London: Belhaven PressBerkes, F., (2008) Sacred Ecology, Sacred Ecology, , New York and London: Routledge, 2Berkes, F., Shifting perspectives on resource management: Resilience and the Reconceptualization of 'Natural Resources' and 'Management (2010) MAST, 9 (1), pp. 13-40Ostrom, E., (1990) Governing the commons, , Princeton U: PressOstrom, E., (2005) Understanding Institutional Diversity, , Princeton University PressGelcich, S., Hughes, T.P., Olsson, P., FolkeC, D.M., Fernandez, M., Foale, S., Gunderson, L.H., Castilla, J.S., Navigating transformations in governance of Chilean marine coastal resources (2011) PNAS, 107 (39), pp. 16794-16799La Pesca continental enAmaerica Latina: sucontribución económica y social e instrumentos normativos asociados, Documento Ocasional 11.

The Most Famous Writer of the Low Countries: Herman Brusselmans Star Author and (Reluctant) Public Intellectual
AbstractThe Flemish writer Herman Brusselmans is the most famous author of the Low Countries. In this article, Herman Brusselmans is analysed as a star author. First and foremost, two striking aspects of Brusselmans’s stardom are analysed: his public visibility and the cult of the private. Attention is then focused on Brusselmans’s experience of celebrity, which he - like many other star authors - thematises in his books. Doing so, he consciously places himself in the context of popular culture. On the other hand, as a result of his celebrity status he has been expected - particularly in the last few years - to assume the role of public intellectual willy-nilly, and this in turn has had consequences for his work.</jats:p
Designing Procedurally Generated Levels
We aim to improve on the design of procedurally generated game levels. We propose a method which empowers game designers to author and control level generators, by expressing gameplay-related design constraints. Following a survey conducted on recent procedural level generation methods, we argue that gameplay-based control is currently the most natural control mechanism available for generative methods. Our method uses graph grammars, the result of the designer-expressed constraints, to generate sequences of desired player actions. These action graphs are used as the basis for the spatial structure and content of game levels; they guide the layout process and indicate the required content related to such actions. We showcase our approach with a case study on a 3D dungeon crawler game. Results allow us to conclude that our control mechanisms are both expressive and powerful, effectively supporting designers to procedurally generate game levels.Computer Science - Media and Knowledge EngineeringIntelligent SystemsElectrical Engineering, Mathematics and Computer Scienc

Development of nature-oriented dairy farm systems with an optimization model: the case of ‘Farming for Nature’ in ‘de Langstraat’, the Netherlands
‘Farming for Nature’, a relatively new policy instrument being tried out in the Netherlands, is evaluated. The concept has been designed to allow dairy farmers to improve nature conservation on their farms. Under the scheme, no manure, fertilizer, or feed – concentrates or roughage - may be imported into farm systems from external sources. The feasibility of such a self-sustaining system and the conditions required for it to deliver the desired results, are explored with a farm-based linear programming model known as FIONA (Farm based Integrated Optimization Model for Nature and Agriculture). The model is explained and applied to ‘de Langstraat’, a region in southern Netherlands. The results show that levels of production under the ‘Farming for Nature’ regime are dependent upon soil fertility and the proportion of land that is suitable for growing arable crops. If all available land on a dairy farm in the scheme is arable land, then high production levels of up to 7,500 kg milk per hectare can be realized. If only 30% of the farm area is suitable for arable crops, then only lower production levels, of about 6,600 kg milk per hectare can be realized. The scheme has positive ecological effects. Both nature and cultural landscape values may benefit significantly from the concept. Improvement in ecological terms however, carries a price in terms of agricultural income. An average dairy farm adopting the concept of ‘Farming for Nature’ experiences an income loss of approximately € 840 per hectare in the short-run (5-10 years). More important is the observation that the scale of such farms in the short-run might be too small to earn an attractive income for its workers, even when fully compensated according to European Union regulations.nature management, dairy farming system, linear programming, farm-economics, Farm Management, Land Economics/Use,
