Moving in a Hierarchized Landscape Changing Border Regimes in Central Kalimantan

Transnational mobility is a common feature among borderland communities. Central Borneo has been a relatively fluid and open riverine-based socio-cultural and economic space since the arrival of colonial states, without much interference from the establishment of International boundaries on local cross-border mobility practices. This applies to the Kenyah, a cluster of related ethnic groups occupying the Apokayan plateau in East Kalimantan (Indonesia), who are historically an integral part of the socio-cultural and economic fabric throughout the major riverine systems of Sarawak (Malaysia). Despite the relative absence of states, Central Borneo has not escaped the onslaught of social differentiation embedded in nation-state identities. The penetration of Sarawak's logging industry has brought the terrestrial re-ordering of the Bornean landscape away from the relative egalitarian social order of river basins into hierarchical social relations embedded in capitalistic modes of production. This has brought about the construction of the Kenyah's visibility as an “Indonesian underclass“ inside Sarawak

THE ROLE OF SCIENTIFIC AND BUSINESS INTEGRITY IN THE FUTURE OF BIOTECHNOLOGY: A SCENARIO ANALYSIS

The emergence of biotechnology in crop and livestock applications has been an issue of great controversy. Proponents argue that the potential benefits are dramatic while opponents have raised many concerns about the technology's risks. The Starlink debacle is a prime example of the undesirable outcomes which the debate has created. Given the controversy, what is the future of biotechnology for food uses? This paper is designed to address this question with a focus on the feasible range of alternative futures (scenarios) that could emerge. As a major variable in this analysis, the integrity of the scientific and business communities plays a critically important role. The paper begins with a description of three key uncertainties-food security, environmental/health impacts, and consumer reaction-that will define the future for biotechnology's use in food applications. Based on these uncertainties, four alternative future scenarios for biotechnology are presented. The role of messenger integrity is then introduced. The integrity of various possible messengers (scientists, businesses, government, and non-profits) is examined. The concept of integrity is then used to address a series of current biotechnology issues. Throughout the paper, comparisons and contrasts between the developed and developing world are made.Research and Development/Tech Change/Emerging Technologies,

EMERGING BUSINESSES: THE SOUTH AFRICAN WINE INDUSTRY CASE

Emerging economies such as South Africa, only a few years out of apartheid, have been feeling the strains of socio-political change. While South Africa has experienced political reform, economic reform and access are slow to come. Currently, South Africa is the 7th largest producer of wine in the world. Although this industry is impressive, the apartheid era production practices have caused primarily the European consumers and media to be vocal about this issue. However, this concern has spread to other regions. The South African government and wine industry must respond to the external and internal market pressures and minimize transaction costs. Both entities want to increase wine exports and expand market share, however, given the socio-economic and political climate in the country neither knows how to manage this difficult process which emanates from deeply rooted distrust of groups within the country. Socio-political constraints facing previously disadvantaged groups (PDG) as emerging business owners need to be understood; and, measures which could be undertaken by government and industry need to be identified. The objectives of this research were to identify: institutional constraints and transaction costs faced by PDGs aspiring toward production and leadership roles in the wine industry; ways the government can collaborate with the KWV to build social capital and promote PDG ownership in the wine industry, thus minimizing social conflict; and, identify industry strategies to increase exports and international market share under the "New South Africa" banner. This analysis was based on primary and secondary data and information gathered on site. Several potential solutions were suggested for ways to include PDGs in the South African wine market while minimizing the impact on the market shares of existing producers. It is anticipated that the window of opportunity to increase exports and involve PDG is quite small.Agribusiness,

ECONOMIC AND SOCIAL CONSEQUENCES OF BIOTECHNOLOGY: A SCENARIO ANALYSIS

Over the years agricultural technology has created remarkable commodity production growth rates and enhanced general economic growth through food production, manufactured goods and trade for most nations. Biotechnology holds the promise of continuing this remarkable record. There is a long list of potential benefits of biotechnology but unfortunately the perceived costs/risks are also many. These concerns have lead to significant consumer reluctance to accept the technology and, in some cases, outright consumer rejection of the technology. To discuss the future of biotechnology, scenario analysis is used to examine the social and economic impact of biotechnology on industrialized and emerging nations. Four scenarios are discussed in detail: biotechnology may be formally or informally banned (Scenario 1), fully accepted (Scenario 2), marketed through strict labeling (Scenario 3), or limited to non-food applications (Scenario 4). Consumer acceptance of this technology will be key to determining which scenario becomes the future for each nation. The likelihood of each scenario is different for each nation, the U.S. will most likely evolve into scenario 2 or 3, while in the EU scenarios 1 or 4 are more likely. Determining the future for emerging nations is extremely complex and dependent on several factors like malnutrition rates, environmental safety and historical trading routes. Each scenario has a major impact on small producers worldwide which ultimately influences the health of rural communities. The analysis indicates that emerging nations are the most sensitive to the timing of decisions being made about the future of biotechnology. If biotechnology becomes a reality, new data will be required to assess the social and economic impact of this technology.Research and Development/Tech Change/Emerging Technologies,

DO THE JAPANESE DISCRIMINATE AGAINST AUSTRALIAN BEEF IMPORTS?: EVIDENCE FROM THE DIFFERENTIAL APPROACH

This paper considers an application of the differential approach to Japanese demand for beef imports from 1970 to 1993. Results of homothetic demand and negative (significant) own-price elasticities indicate that the Japanese did not discriminate against Australian beef, but the decrease in Australia's trade shares was due to changes in relative prices.Japan, Beef Imports, Rotterdam model, CBS model, International Relations/Trade,

MEMBERS' FINANCIAL EVALUATION AND COOPERATIVES' DECISION PROCESSES

The paper presents an analysis of cooperative investment decision based on the coalition theoretical framework (Staatz 1983, 1987, 1989). According to this framework, cooperatives can be considered as coalitions of groups with different interests. The behavior of any cooperative is determined by the interaction of its many groups (different types of farmers, managers, lenders, input suppliers, buyers, etc.) with different objectives. The group that can impose its will on the coalition will determine the cooperative's strategy. The other parties may accept this leadership, leave the cooperative or try to use their bargaining power to modify the final outcome. The paper discusses the impact of group bargaining on cooperatives' decision process. In particular, the paper addresses the issues related to the consequences of members' heterogeneity on cooperative efficiency. The proposed model utilizes tools from financial theory already successfully applied in the literature (Peterson 1992, Hendrikse 1998) providing a more detailed insight into the determinants of the cooperative decision process. The paper shows that cooperatives evaluate investments differently from IOFs due to the unique characteristics of their patrons compared to other types of investors.Agribusiness, Agricultural Finance,

Immune Response and Immunolmodulation in Chronic Hepatiitis B Virus Infection

Despite the presence of an effective vaccine since 1982, chronic hepatitis B virus infection (CHB) still ranks among the highest causes of mortality from infectious diseases worldwide. The studies presented in this thesis were performed to get a better insight into the anti-viral immune response after hepatitis B virus (HBV) infection, and to identify factors in this immune response that contribute to persistent disease. Dendritic cells (DC) play an important role in the induction of anti- viral immune responses. In this thesis we show that two important blood precursor DC, myeloid DC and plasmacytoid DC, are functionally impaired in patients with chronic hepatitis B and this might be an important mechanism by which HBV evades an adequate immune response, leading to viral persistence and disease chronicity. Information about character and grade of the intrahepatic immune response in viral hepatitis is important for evaluation of disease stage and effect of therapy. Complications like haemorrhage provide a limitation to frequently performing standard tissue needle biopsies. The Fine-needle-aspiration-biopsy (FNAB) is an easy and atraumatic alternative and we show that flow cytometry of fine-needle-aspiration- biopsy of the liver allows reliable analysis of lymphocytes obtained from the intrahepatic compartment, in patients with viral hepatitis. Subsequently, the FNAB is used to show that there likely is an important role for intrahepatic HBV-specific CD8+ T-cells in clearing acute HBV infection. Furthermore, we have attempted to boost the impaired T-cell responses in patients with chronic HBV infection, using conventional anti-viral therapy. In in vivo immunization (IVI) of CHB patients, following rapid virus suppression by interferon-lamivudine combination therapy, lamivudine was withdrawn intermittently during continued interferon (IFNα) therapy. Although initially IVI was able to transiently suppress viral replication in two patients with CHB, in a subsequent pilot study the magnitude of the induced T-cell response was insufficient to cause a sustained virological effect in the majority of patients. It is unknown why treatment with IFNα leads to a response in only a minority of patients with chronic HBV. We show that in non-responders and not in responders there was a significant increase in the frequency of regulatory T cells (Treg) and IL-10 secreting cells during treatment with IFNα. Treg depletion resulted in increased proliferation capacity and increased frequencies of HBV-specific INFgamma-producing cells, but did not affect the frequency of IL-10 producing cells measured during the course of the treatment. This study indicates that there may be an important role for Treg in HBV- persistence during and after IFNα therapy

Price Determinants in Top Quality E-Auctioned Specialty Coffees

The US specialty coffee industry has grown from $1 billion in 1990 to$11 billion in 2006 and is expected to continue to grow into the foreseeable future. This growth particularly depends on prices coordinating the specialty coffee supply chain through two-way information exchange between roasters and producers. We analyze the determinants of specialty coffee prices by estimating a hedonic price function for specialty Central and South American coffees traded at e-auctions. We hypothesize that since specialty coffee is a differentiated product, prices will be determined by both sensory and reputation attributes. The results show that prices are influenced by the quality rating, which is a sensory variable, and by the quality rankings established in the cupping competition previous to the auction, the country of origin and the coffee variety, which are reputation variables. In addition, the macro variables, harvest year and commodity price were found to be significant.Specialty coffee, hedonic price analysis, differentiated food pricing, sensory attributes, reputation attributes, Demand and Price Analysis,
