Factors influencing adoption of improved grassland management by small-scale dairy farmers in central Mexico and the implications for future research on smallholder adoption in developing countries

There have been limited recent advances in understanding of what influences uptake of innovations despite the current international focus on smallholder agriculture as a means of achieving food security and rural development. This paper provides a rigorous study of factors influencing adoption by smallholders in central Mexico and builds on findings to identify a broad approach to significantly improve research on and understanding of factors influencing adoption by smallholders in developing countries. Small-scale dairy systems play an important role in providing income, employment and nutrition in the highlands of central Mexico. A wide variety of practices and technologies have been promoted by the government public services to increase milk production and economic efficiency, but there have been very low levels of uptake of most innovations, with the exception of improving grassland through introduction of grass varieties together with management practices. A detailed study was conducted with 80 farmers who are already engaged with the use of this innovation to better understand the process of adoption and identify socioeconomic and farm variables, cognitive (beliefs), and social–psychological (social norms) factors associated with farmers' use of improved grassland. The Theory of Reasoned Action (TRA) was used as a theoretical framework and Spearman Rank Order correlation was conducted to analyse the data. Most farmers (92.5%) revealed strong intention to continue to use improved grassland (which requires active management and investment of resources) for the next 12 months; whereas 7.5% of farmers were undecided and showed weak intention, which was associated with farmers whose main income was from non-farm activities as well as with farmers who had only recently started using improved grassland. Despite farmers' experience of using improved grassland (mean of 18 years) farmers' intentions to continue to adopt it was influenced almost as much by salient referents (mainly male relatives) as by their own attitudes. The hitherto unnoticed longevity of the role social referents play in adoption decisions is an important finding and has implications for further research and for the design of extension approaches. The study demonstrates the value and importance of using TRA or TPB approaches to understand social cognitive (beliefs) and social–psychological (social norms) factors in the study of adoption. However, other factors influencing adoption processes need to be included to provide fuller understanding. An approach that would enable this, and the development of more generalisable findings than from location specific case studies, and contribute to broader conceptualisation, is proposed.

Economic commodity or environmental crisis? An interdisciplinary approach to analysing the bushmeat trade in central and west Africa

Bushmeat is a large but largely invisible contributor to the economies of west and central African countries. Yet the trade is currently unsustainable. Hunting is reducing wildlife populations, driving more vulnerable species to local and regional extinction, and threatening biodiversity. This paper uses a commodity chain approach to explore the bushmeat trade and to demonstrate why an interdisciplinary approach is required if the trade is to be sustainable in the future.

Oppida, agglomerations and suburbia: the bibracte environs and new perspectives on late Iron Age urbanism in central-eastern France

This paper explores the nature and chronology of La Tène and early Roman unenclosed agglomerations in central-eastern France. It has been prompted by the discovery of a c. 115 ha La Tène D2b/Augustan (c. 50 bc to ad 15) site close to Bibracte in the Morvan, located around the source of the River Yonne. This complex provides a new perspective on the chronology and role of Late La Tène and early Roman unenclosed settlements, adding further complexity to the story of the development of Late La Tène oppida. It indicates that these ‘agglomerations’ followed remarkably varied chronological trajectories, raising important issues concerning the nature of landscape and social change at the end of the Iron Age. Dieser Aufsatz untersucht den Charakter und die Datierung von latènezeitlichen und frührömischen offenen Siedlungen im östlichen Zentralfrankreich. Die Anregung dazu erfolgte durch die Entdeckung einer Latène D2b-zeitlichen bis augusteischen (ca. 50 v. Chr. – 15 n. Chr.) Anlage im Morvan bei Bibracte, die ca. 115 ha Fläche bedeckt und sich um die Quellen des Flusses Yonne erstreckt. Es wird vorgeschlagen, dass dieser Siedlungskomplex eine Ergänzung, aber auch einen Kontrast zu den üblichen Interpretationsmodellen von spätlatènezeitlichen und frührömischen, offenen Großsiedlungen und ihrer zeitlichen Entwicklung darstellt, und weiter zur Komplexität der Entwicklung spätlatènezeitlicher Oppida beiträgt. Es deutet sich an, dass einige der ‘Agglomerationen’ anderen Entwicklungslinien folgen, die wichtige Fragen zur Landschaftsgenese und zum sozialen Wandel am Ende der Eisenzeit aufwerfen. Cet article a pour but d'explorer la nature ainsi que la chronologie des agglomérations ouvertes apparaissant à La Tène Final et au début de la période gallo-romaine du Centre-Est de la France. Il fut inspiré et écrit suite à la découverte dans le Morvan d'un site de 115 ha datant de La Tène D2b et de la période Augustéenne (50 av. J.C. à 15 ap. J.C.) s'étirant autour des Sources de l'Yonne. Cette agglomération apporte de nouvelles perspectives sur la chronologie et sur le rôle des habitats ouverts à la fin de l'Âge du Fer ainsi qu'au début de l'époque gallo-romaine apportant des éléments amenés à renforcer le caractère complexe de l'histoire du développement des oppida à La Tène Final. Cette synthèse tend à démontrer que ces agglomérations suivaient des trajectoires chronologiques variées, élevant un certain nombre de questions, et donc des nouvelles problématiques, concernant la nature du paysage et du changement social à la fin de l'Âge du Fer.

Real estate and social inequality in Latin America: approaches in Argentina, Brazil, Chile and Colombia

Latin America is known as the most unequal region in the world, where extreme displays of wealth and exposure to scarcity lay bare in the urban landscape. Inequality is not just a social issue; it has considerable impact on economic development. This is because social inequality generates instability and conflict, which can create unsettling conditions for investment. At the macro level, social inequality can also present barriers to economic development, as most government policies and resources tend to be directed in solving social conflict rather than to promote and generate growth. This is one of the reasons usually cited in explaining the development gap between Latin America and other emerging economies, take East Asia for example - they have similar policies to those applied recently in Latin America, but are achieving better growth. The other reason cited is institutional; this includes governance as well as property rights and enforcement of contracts. The latter is the focus of this chapter.

Multi-criteria analysis and the resolution of sustainable development dilemmas: a stakeholder management approach

We demonstrate that stakeholder-oriented multi-criteria analysis (MCA) can adequately address a variety of sustainable development dilemmas in decision-making, especially when applied to complex project evaluations involving multiple objectives and multiple stakeholder groups. Such evaluations are typically geared towards satisfying simultaneously private economic goals, broader social objectives and environmental targets. We show that, under specific conditions, a variety of stakeholder-oriented MCA approaches may be able to contribute substantively to the resolution or improved governance of societal conflicts and the pursuit of the public good in the form of sustainable development. We contrast the potential usefulness of these stakeholder-oriented approaches – in terms of their ability to contribute to sustainable development – with more conventional MCA approaches and social cost–benefit analysis.

Research agenda for the built environment in Latin America

This paper disseminates the outcomes of a series of interdisciplinary and multi-sector research seminars that focused on current development problems in a region of fast urban growth. Qualitative data was collected during round table discussions and workshops involving practitioners and government officials from some of the largest economies in Latin America. The authors then grouped these discussions into coherent themes and framed them into current scholarly debates. After assessing the suitability of theory to respond to practice, the paper concludes with four key areas for further research, with the final aim to encourage more scholarly analysis that can better inform development policy in emerging economies.

Future change of climate in South America in the late twenty-first century: intercomparison of scenarios from three regional climate models

Regional climate change projections for the last half of the twenty-first century have been produced for South America, as part of the CREAS (Cenarios REgionalizados de Clima Futuro da America do Sul) regional project. Three regional climate models RCMs (Eta CCS, RegCM3 and HadRM3P) were nested within the HadAM3P global model. The simulations cover a 30-year period representing present climate (1961-1990) and projections for the IPCC A2 high emission scenario for 2071-2100. The focus was on the changes in the mean circulation and surface variables, in particular, surface air temperature and precipitation. There is a consistent pattern of changes in circulation, rainfall and temperatures as depicted by the three models. The HadRM3P shows intensification and a more southward position of the subtropical Pacific high, while a pattern of intensification/weakening during summer/winter is projected by the Eta CCS/RegCM3. There is a tendency for a weakening of the subtropical westerly jet from the Eta CCS and HadRM3P, consistent with other studies. There are indications that regions such of Northeast Brazil and central-eastern and southern Amazonia may experience rainfall deficiency in the future, while the Northwest coast of Peru-Ecuador and northern Argentina may experience rainfall excesses in a warmer future, and these changes may vary with the seasons. The three models show warming in the A2 scenario stronger in the tropical region, especially in the 5A degrees N-15A degrees S band, both in summer and especially in winter, reaching up to 6-8A degrees C warmer than in the present. In southern South America, the warming in summer varies between 2 and 4A degrees C and in winter between 3 and 5A degrees C in the same region from the 3 models. These changes are consistent with changes in low level circulation from the models, and they are comparable with changes in rainfall and temperature extremes reported elsewhere. In summary, some aspects of projected future climate change are quite robust across this set of model runs for some regions, as the Northwest coast of Peru-Ecuador, northern Argentina, Eastern Amazonia and Northeast Brazil, whereas for other regions they are less robust as in Pantanal region of West Central and southeastern Brazil.

Primary immunodeficiency diseases in Latin America: Proceedings of the Second Latin American Society for Immunodeficiencies (LASID) Advisory Board

Early diagnosis and appropriate therapy are essential for the best prognosis and quality of life in patients with primary immunodeficiency diseases (PIDDs). Experts from several Latin American countries have been meeting on a regular basis as part of an ongoing effort to improve the diagnosis and treatment of PIDD in this region. Three programmes are in development that will expand education and training and improve access to testing facilities throughout Latin America. These programmes are: an educational outreach programme (The L-Project); an immunology fellowship programme; and the establishment of a laboratory network to expand access to testing facilities. This report provides the status of these programmes based on the most recent discussions and describes the next steps toward full implementation of these programmes. (C) 2010 SEICAP.

U-Pb-Hf-trace element systematics and geochronology of zircon from a granulite-facies metamorphosed mafic-ultramafic layered complex in Central Brazil

Zircon recrystallization is a common process during high-grade metamorphism and promotes partial or complete resetting of the original isotopic and chemical characteristics of the mineral and thus complicates U-Pb geochronological interpretation. In Central Brazil, this complexity may be illustrated by three composite mafic-ultramafic intrusions metamorphosed under amphibolite-to-granulite conditions. Their ages of emplacement and metamorphic ages have been a matter of controversy for the last thirty years. The Serra da Malacacheta and Barro Alto complexes make up the southernmost of these layered bodies and four samples from distinct rock types were investigated in order to verify the consequences of metamorphic alteration of zircon for U-Pb dating. Cathodoluminescent imaging reveals internal features which are typical of concomitant dissolution-reprecipitation processes, such as convolute zoning and inward-moving recrystallization fronts, even in samples in which partially preserved igneous textures are observed. Due to this extensive alteration, LA-ICPMS U-Pb isotopic analysis yielded inconclusive data. However, in situ Hf isotopic and trace-element analyses help to clarify the real meaning of the geochronological data. Low Lu/Hf (<0.004) and homogeneous (176)Hf/(177)Hf(t) values imply that the zircon populations within individual samples have crystallized in a single episode, despite the observed variations in age values. Trace element signatures of zircon grains from garnet-bearing samples reveal that they were unreactive to the development of the peak metamorphism mineral assemblage and, thus, the main chemical feature in such grains is attributed to a coupled dissolution-reprecipitation process. However, in the Cafelandia amphibolite an additional alteration process is identified, probably related to the influx of late-stage fluids. Combined isotopic and geochemical investigation on zircon grains allowed the distinction of two magmatic events. The first corresponds to the crystallization of the Serra da Malacacheta Complex and characterizes a juvenile magmatism at similar to 1.3 Ga. The younger episode, recognized in the Barro Alto Complex, is dated at ca. 800 Ma and is represented by mafic and ultramafic rocks showing intense contamination with continental crust, implying that the emplacement took place, most likely, in a continental back-arc setting. Altered zircon domains as well as titanite grains date the metamorphic event at ca. 760-750 Ma. (C) 2011 Elsevier B.V. All rights reserved.

Fakalakalaka : The impact of a Tongan notion of development in a contemporary transnational world

This paper aims to explore a Tongan notion of development –'fakalakalaka' – in light of Western notions of development. Two case studies of international development aid schemes illustrate the impact of Tongan development ideas in practice. Drawing on a number of ethnographers' work on Tonga, 'fakalakalaka' appears broader than the Western notion of development. The latter is characterised by influential ideals of controllability and industrialisation. The notion of development among Tongans, on the other hand, tends to be directed by an underlying persistence that, for instance, reflects Tongan core values regarding social organisation. The production of textile 'koloa', controlled by women, emerges as central to the accomplishment of this three-dimensional development notion of intertwined physical, mental and spiritual aspects. The importance attributed to this specific kind of textile has increased in recent years and found two additional roles, or development strategies, in Tongans' contemporary transnational world.

From old to new developmentalism in Latin America

O fracasso do consenso de Washington e das políticas macroeconômicas, baseadas em altas taxas de juros e taxas de câmbio não-competitivas para promover o crescimento da economia, levou os países da América Latina a formularem estratégias nacionais de desenvolvimento. O novo desenvolvimentismo é uma estratégia alternativa não apenas à ortodoxia convencional, mas também ao antigo nacional-desenvolvimentismo latino-americano. Enquanto o antigo nacional desenvolvimentismo era baseado na tendência à deterioração dos termos de troca e, adotando uma abordagem microeconômica, propunha planejamento econômico e industrialização, o novo nacional-desenvolvimentismo pressupõe que a industrialização foi alcançada, apesar de em diferentes estágios em cada país, e argumenta que, para assegurar rápidas taxas de crescimento e o catch up, a tendência que deve ser neutralizada é a da sobrevalorização da taxa de câmbio. Contrariamente à economia convencional, um estado capaz continua sendo o instrumento chave para assegurar o desenvolvimento econômico, a política industrial continua sendo necessária; mas o que distingue a nova abordagem é principalmente o crescimento com poupança interna, ao invés de com poupança externa. Uma política macroeconômica baseada em taxas de juros moderadas e uma taxa de câmbio competitiva, e não altas taxas de juros e moeda sobreapreciada conforme recomenda a ortodoxia convencional.

The Profile of a Manager in Higher Education Institution in Latin America: The Case of the EBAPE

The aim of this study is to analyze the profile of today’s manager, according to the classical management literature, working on internationalized higher education institute. This paper draws together knowledge about the manager’s profile in a corporate environment and how it can be appreciated in a higher education institute all of this taking into consideration the environment that nowadays exists in these institutions. Data were collected through semi-structured interviews, with professors of the Fundacao Getulio Vargas, more specific on their Public and Business Administration School (EBAPE), which had active roles on its development, internationalization and during some point in time their management. The findings obtained where analyzed under the perspective brought by the theoretical reference framework, and, based on this approach is represented the manager whom could have a better perspective to administrate a higher education institute.

Need and opportunity: what are the main security threats to the pharmaceuticals industry in Latin America?

Os preços altos de produtos farmacêuticos patenteados sempre têm sido uma polêmica na América Latina. Considerando as disparidades económicas na região e a falta histórica do desenvolvimento, muitas vezes os preços altos servem como barreiras contra o acesso aos medicamentos essenciais. Por um lado, as companhias farmacêuticas dizem que os preços elevados são necessários para financiar os processos de pesquisa e desenvolvimento e para gerar um retorno do investimento lucrativo. Por outro lado, os consumidores, tanto privados como públicos, dizem que os preços altos têm resultado em uma falta histórica de medicamentos baratos. Neste debate, ambos lados têm realizado uma série de manobras e contramanobras que têm exposto algumas das vulnerabilidades do setor. Utilizando vários métodos de análise e entrevistas com profissionais no setor, este projeto analisa as vulnerabilidades do setor para determinar o risco, ao mesmo tempo tentando a responder à pergunta: Quais são as ameaças principais na segurança da indústria farmacêutica na América Latina? Justificação deste projeto é o aumento dos crimes relacionados aos produtos farmacêuticos na última década, que têm exposto os pacientes a um número de riscos mais alto. Uma compreensão das ameaças principais é necessária para melhor mitigar o risco, garantir a integridade de produtos e preservar a saúde pública.
