The History, Present Condition, and Future of the Molluscan Fisheries of North and Central America and Europe: Volume 2, Pacific Coast and Supplemental Topics

Over 100 molluscan species are landed in Mexico. About 30% are harvested on the Pacific coast and 70% on the Atlantic coast. Clams, scallops, and squid predominate on the Pacific coast (abalone, limpets, and mussels are landed there exclusively). Conchs and oysters predominate on the Atlantic coast. In 1988, some 95,000 metric tons (t) of mollusks were landed, with a value of $33 million. Mollusks were used extensively in prehispanic Mexico as food, tools, and jewelry. Their use as food and jewelry continues. Except in the States of Baja California and Baja California Sur, where abalone, clams, and scallops provide fishermen with year-round employment, mollusk fishing is done part time. On both the Pacific and Atlantic coasts, many fishermen are nomads, harvesting mollusks wherever they find abundant stocks. Upon finding such beds, they build camps, begin harvesting, and continue until the mollusks become so scarce that it no longer pays to continue. They then look for productive beds in other areas and rebuild their camps. Fishermen harvest abalones, mussels, scallops, and clams by free-diving and using scuba and hooka. Landings of clams and cockles have been growing, and 22,000 t were landed in 1988. Fishermen harvest intertidal clams by hand at wading depths, finding them with their feet. In waters up to 5 m, they harvest them by free-diving. In deeper water, they use scuba and hooka. Many species of gastropods have commercial importance on both coasts. All species with a large detachable muscle are sold as scallops. On the Pacific coast, hatchery culture of oysters prevails. Oyster culture in Atlantic coast lagoons began in the 1950's, when beds were enhanced by spreading shells as cultch for spat. (PDF file contains 228 pages.

U.S.-Mexico Trade: Pulling Together or Pulling Apart?

This report finds little likelihood that a NAFTA, by itself, will lead to the most dismal scenarios. But OTA’s analysis also indicates that market forces alone are not likely to produce the social and economic rewards the heads of both states have promised from a free trade agreement

Businessmen and Protection Patterns in Dangerous Contexts: Putting the Case of Guadalajara, Mexico in Perspective

Struggling with a variety of security challenges, business owners and economic elite have developed strategic behaviors for protections. This dissertation aims to understand the latter’s mechanisms once implemented by the economic elite. Based on qualitative data collected in Guadalajara, I demonstrate how this elite demand and co-produce protection, and how by doing so, they are shaping Jalisco’s policing patterns and social order. As start, I discuss the threats facing the urban proprietors and consequently how their perception of the problem leads to the formulation of the problem, their problem. Then I analyse their protection suppliers whether governmental or non-governmental, illustrating these latter coalition, collusion and collision dynamics. I state that businessmen are protected by selective and personalized access to law enforces while explaining how they purchase protection from actors in the gray zones laying between public-private, formal-informal and legal-illegal realms. Finally, the research engage with self-protection production explaining how they use their repertory of collective (in)action to interact with state agencies and other protection sources.Se heurtant à divers problèmes de sécurité, les entrepreneurs mexicains ont développé des comportements routiniers ou stratégiques dans la recherche d’une protection. Cette thèse a pour objectif de comprendre les mécanismes de protection mis en place par cette élite économique. En se basant sur des données qualitatives collectées à Guadalajara, je montre comment cette élite exige et co-produise de la protection, et comment à travers cela, ils contribuent à façonner les structures de maintien de l’ordre et de l’ordre social de Jalisco. Je commence par examiner les menaces qui pèsent sur les propriétaires urbains et comment cette perception conduit à la formulation du problème, considéré par cette élite comme leur problème. J’analyse ensuite l’enchevêtrement des fournisseurs de la protection, soit gouvernementaux et non-gouvernementaux, tout en illustrant leurs dynamiques de coalition, de collusion et de collision. J’affirme que les hommes d’affaires sont protégés grâce à un accès sélectif et personnalisé aux forces de l’ordre, achetant même une protection, de gré ou de force, à des acteurs situés dans les zones grises. Enfin, la recherche clarifie le cas des hommes d’affaires qui participent à produire de l’auto-protection en employant leur ample répertoire d’initiatives collectives afin d’interagir avec les agences de l’État et d’autres sources de protection.Programme doctoral en Science politique, Mention Sociologie Politique Comparé

Blurred Borders: Trans-Boundary Impacts & Solutions in the San Diego-Tijuana Border Region

Over the years, the border has divided the people of San Diego County and Tijuana over language, culture, national security, public safety and a host of other cross-border issues ranging from human migration to the environment. For some, the 'us' versus 'them' mentality has become more pervasive following the tragedy of September 11, 2001, with a growing number of San Diegans focusing greater attention on terrorism and homeland security, as well as the need to re-think immigration policy in the United States as a means of fortifying the international border. This is validated by a recent KPBS/Competitive Edge research poll that found 46% of English-speaking San Diegans desiring that the U.S. impose tighter restrictions on the border. Yet the question remains: if San Diegans and Tijuana are so different, why is our shared port of entry the most busily crossed international border in the world with over 56 million crossings a year? The answer is simple. Opposites attract. The contrasts and complementarities between San Diego and Tijuana are so powerful that residents, as well as visiting tourists and business people, endure post-9/11 traffic and pedestrian delays to cross the border for work, school, cultural enrichment, maintaining family ties or sheer economic necessity

Successful organizational learning in the management of agricultural research and innovation: The Mexican produce foundations

"Since the 1980s, developing countries' agriculture has become more complex and diversified. In general, the public research and extension institutions in these countries were criticized for not participating in the emergence of the most dynamic agricultural markets. In recent years, many of these institutions have struggled to adapt to the new environment but they could not overcome the hurdles posed by organizational rigidities, strict public regulations, deteriorating human capital, shrinking budgets and a model of science that hampered their integration into dynamic innovation processes. In general, developing countries applied similar agricultural research policies: separation of financing and implementation of research, reductions in direct budgetary allocations to research and extension institutions, elimination or major reduction of public extension, and introduction of competitive grants programs to induce a transformation of research organizations. Strong anecdotal information suggests that these policies had limited impact on the quality and pertinence of research, and on the performance of the public research institutions. Using a different set of instruments, the Mexican Produce Foundations (PF) had major and diverse impacts on the agricultural innovation and research systems. These impacts resulted mostly from activities the PF introduced as they learned to manage funds for research and extension, and to a lesser extent from the activities they were created for, i.e., manage a competitive fund for agricultural research and extension. The PF were able to introduce these activities because they developed strong abilities to learn, including identifying knowledge gaps and defining strategies to fill them. The questions this report seeks to answer are how an organization that manages public funds for research and extension could sustain organizational innovations over extended periods, and how it could learn and adapt to maximize its impact on the agricultural innovation system. Previous studies found that human resources, organizational cultures and governance structures are three of the most important factors influencing institutional change and innovative capabilities. Despite their importance, these factors have been largely neglected in the literature on agricultural research and extension policies. This document analyzes what role these factors played in the Mexican experience." from textAgricultural research, Agricultural innovation, Developing countries,

The potential of geographical information system-based modelling for aquaculture development and management in South Western Bangladesh

This study describes the delineation of appropriate sites for aquaculture using remote sensing, GPS and GIS. A 1996 composite Landsat TM image covering the south-western part of Bangladesh was used to identify water bodies, the extent of brackish water and associated land use features in the image. The Remote Sensing image was complemented by digitised secondary data from a range of sources, including hard copy maps to produce a GIS database which included environmental layers such as water bodies, rivers, soils, land use, temperature, rainfall, salinity and pH. The database also included infrastructural issues, such as roads, railways, processing plants, towns and cities. A series of GIS models were developed in order to identify and prioritise the most suitable areas for freshwater prawn, tilapia and carp and brackish water shrimp and crab farming. A range of scenarios for land allocations were used to develop a series of resource use models linked to likely production outcomes. Global warming and accelerated sea level rise is considered in the study area with different sea level rise scenarios of 50, 100, 150 and 200cm. The consequence of land losses and displacement of the population from the area in different situations is discussed. The economic characteristics of shrimp farming and alternative land uses in the Khulna region were also considered. Five land use options were studied based on economic output and job potential. Among these, brackish water shrimp and crab culture, moderately saline tolerant tilapia and prawn culture, fresh water carp culture and traditional rice production systems, and fresh water prawn culture performed best followed by brackish water shrimp and crab culture. This study showed the extent of potential for aquaculture in the Khulna region and further demonstrates the usefulness of GIS as an aquaculture-planning tool. Model programming was also found to be very useful tool to enabling regenerating of multiple scenarios very quickly. Overall, GIS modelling associated with remote sensing has great potential for informed decision-making in aquatic production systems and optimising management of natural resources in a region where they are already under considerable pressure. The implications for use of these systems in reducing land use conflict and sector planning for the region are discussed

The Contemporary Face of Transnational Criminal Organizations and the Threat they Pose to U.S. National Interest: A Global Perspective.

Traditional organized crime groups have consistently posed issues for la w enforcement; however, the contemporary TCOs present an even greater security risk and threat. TCOs thrive in countries with a weak rule of law and present a great threat to regional security in many parts of the world. Bribery and corruption employed by these groups further serve to destabilize already weak governments. These TCOs also present a major threat to U.S. and world financial systems by exploiting legitimate commerce, and in some cases creating parallel markets (“Transnational Organized,” 2011) . Finally, one of the most significant threats posed by contemporary TCOs is their alliances and willingness to work with terrorist and extremist organizations. This paper will focus on contemporary TCOs by giving a brief overview of the most common criminal enterprises associated with these groups, the nexus between various TCOs, the nexus between TCOs and terrorist and extremist groups, case studies highlighting the nexus, and the threats they pose to U.S. national interests

The meaning of 'social' in Mexican social housing: a study of housing developments in Mazatlán, Mexico

This thesis explores the social housing process in Mexico, which is mainly defined by the planning, construction and provision of housing, and ends with the delivery of the dwellings, overlooking the post-occupational stage of housing. This research focuses first on INFONAVIT, a Mexican institution in charge of administering a housing fund for workers since 1972 that has received many critiques because of its disconnection from the housing process since the late 1980s, when law reforms delegated the construction of housing to the private sector. Secondly, on private actors such as developers and construction companies, who have been critiqued due to the decreasing material quality and size of the houses. Finally, on social housing residents’ experiences with their houses and the built environment’s impact on their everyday life. Through an extensive qualitative approach, 19 actors involved in the housing design, planning and production process, and 50 residents in four housing projects in the city of Mazatlán, Mexico, were interviewed during a two-stage visit to Mexico City and Mazatlán. Along with the development of semi-structured interviewing, the architectural design of social housing units and the housing policies and regulations behind its production were analysed, making use of a multi-methods strategy combining direct observation, document analysis, analysis of secondary sources, and the use of photographs, architectural layouts and sketches. The findings of this research contribute to a deeper understanding of the meaning of ‘social’ in social housing, while acknowledging the need for a socially responsible planning and architectural design process. Due to the multi-disciplinary theoretical basis of this study, this thesis aims to be of interest not only to researchers, but also to inform practitioners in their decisions, including planners, architects, and policy makers
