STRATEGIC AGRIBUSINESS OPERATION REALIGNMENT IN THE TEXAS PRISON SYSTEM

Mathematical programming-based systems analysis is used to examine the consequences of alternative operation configuration for the agricultural operations within the Texas Department of Criminal Justice. Continuation versus elimination of the total operation as well as individual operating departments are considered. Methodology includes a firm systems operation model combined with capital budgeting and an integer programming based investment model. Results indicate the resources realize a positive return as a whole, but some enterprises are not using resources profitably. The integer investment model is found to be superior for investigating whether to continue multiple interrelated enterprises.agribusiness, enterprise selection, mathematical programming, optimal enterprise organization, Agribusiness,

The economics of generating and maintaining plant variety rights in China:

Notwithstanding the ambiguous research and productivity promoting effects of plant variety protections (PVPs), even in developed countries, many developing countries have adopted PVPs in the past few years to comply with their Trade-Related Aspects of Intellectual Property Rights (TRIPS) obligations. Seeking and maintaining PVPs reserves options to an expected revenue stream from the future sale of protected varieties, the value of which varies for a host of reasons. In this paper we empirically examine the pattern of plant variety protection applications in China since its PVP laws were first introduced in 1997. We place those PVP rights in the context of China's present and likely future seed markets to identify the economic incentives and institutional aspects that influence decisions to develop and apply for varietal rights.intellectual property, patents, Ownership, Plant propagation, plant breeding, Trade policies, Plant introduction, Crop performance, China,

African seed systems : the crises of food security and the rights of the farmer in Africa's globalising food regime

A research report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Arts (International Relations), 2017Through a close reading of the changes that have occurred within African agriculture using Food Regime Theory, this study will attempt to further understand the impact that has been felt by small-scale farmers who are a dominant feature of African agriculture. This paper will seek to understand the influence that the increased corporatization of agriculture through globalization has had on the small-scale farmer in Africa. As agriculture has become more and more corporatized and commodi:ied, it becomes important to consider the changes that have occurred for those actors within the industry and how these changes will impact them. This paper is attempting to do that through a close reading of the changes that have taken place within an integral part of the agricultural process: the seed.GR201

Property Claims in GM and Non-GM crops

Conceptualising the ongoing conflict over GM versus non-GM crops in the frame of property rights one can see that economic valorisation dynamics and aspirations are working on both sides, within two differently evolving agri-food paradigms, with biotechnology companies propagating intellectual property rights on seeds and crops within a productivist strategy, and with retailer chains, NGOs, farmer associations claiming generic names and labels as public property rights on identity preserved crops within a consumerist strategy. The analysis shows that the direction and strength of the dynamics depends much on the physical intricacies and the social relations which are implicated in these two types of intangible property. As the development of the intangible property rights lies at the heart of postindustrial knowledge economies, the study of the GM conflict is also instructive for understanding social change in the agri-food sector and in the society more generally
