Economia e ecologia: um efoque global

Este artigo discute a recente contribuição de Elmar Altvater em economia política internacional cujo tema são as conseqüências econômicas e ecológicas da difusão do sistema de produção fordista. Atenção especial é dada a tese desoladora sobre os países em desenvolvimento, que decorre de suas trajetórias de pobreza e degradação ambiental prescritas no modelo de Altvater. Argumenta-se que a confiança na regulação supranacional para resolver os problemas correntes destes países pode enfrentar serias restrições políticas e econômicas.

The role of the state in health public policies: an overview of the debate on the concept of State and the Brazilian case

This article is the result of a narrative literature review. The objective is to show the development of an overview on the ideological debate on the design of state health policies. We argue that the role of the state in the development of health policy, even under the pressure of the global market, may create alternatives to promote and drive economic and social development, meaning they are not subject to economic constraints imposed by the liberal ideal of market. Here is a part of a theoretical discussion about the construction and presence of the State in Latin America, particularly in Brazil. We take the approaches of the Marxist tradition and liberal to the issue as reference. This discussion allows us to understand the historical role of the state in the maintenance of social policies, specifically health, is an alternative to public control eases the intense capital mobility promoted by economic globalization. In this sense, the theme makes the Brazilian health an important issue of social sciences, why is the historicity of the construction of the Brazilian health system, as a public policy that can mirror the actual reconstruction of the institutional framework of the Brazilian state with the establishment instances of negotiation between the various spheres of power that strengthen the state in this process of democratization of Brazilian society.

Fuelwood collection and consumption: a case study in Lupeta Tanzania

Fuelwood is a major resource in rural areas. Fuelwood collection and consumption habits were monitored in Lupeta, Tanzania through household interviews and fuelwood collection walks. Social dimensions, economic aspects of fuelwood, and alternative fuel sources were also examined. The study found that for all wealth classes, fuelwood is the primary source of fuel used within the village, with the middle and upper classes occasionally supplementing fuelwood with charcoal. Women collect and consume fuelwood for cooking. The majority of women (69%) prefer to use charcoal because fuelwood collection is labor intensive and time consuming. While the use of charcoal would provide more time for other required household activities, local economic constraints inhibit their adoption. The fuel shift from biomass fuels to transition fuels is happening slowly in Lupeta from fuelwood to charcoal. As fuelwood becomes scarcer, improved methods will need to be adopted or the fuel source will change.

Different levels of policy change: A comparison between the public discussion on social security in Sweden and in Finland

The deep economic recession that hit Sweden and Finland at the beginning of the 90s, and the fall in public revenues and rapidly growing public debts that followed on it, triggered a development of cutbacks and restructuring measures which has resulted in a scientific debate over what this has meant for these countries’ systems of social policy, traditionally resting on the Nordic welfare state paradigm. In this connection, questions of to what extent changes made can be ascribed mainly to the economic constraints posed by the recession at all, or rather, to other more long-term societal trends or phenomena, including globalisation, European integration and/or ideational or ideological shifts among influential (elite) groups, have often been touched upon. Applying an ideas-centred approach, this paper attempts to contribute to the knowledge on the reasoning of influential elite societal groups in social policy issues before, during and after the 90’s recession, by empirically analysing their statements on social security made in the press. A distinction is made between three different levels of proposed policy changes, reaching from minor alterations of single programs to changes of the policy paradigm. Results show that the 1990s did not only mean the emergence of suggestions for minor cutbacks in and alterations of prevailing programmes. The share of suggestions implying de facto a (further) departure from the basic features of the social security system also showed that the model was under continuous pressure throughout the 90s. However, many of the changes suggested were not justified by any clear references to a policy paradigm in either country (or not justified at all). Instead, references to “purely” structural justifications did become more common over time. In this respect, as regards social security, our results cannot confirm the fairly popular notion among many researchers of a clearly ideological attack on the welfare state. However, it remains uncertain whether and to what extent the increased proportion of references to “structural realities” in the 90s should be interpreted as an indication of a change in the idea of what the welfare state is and what the goals behind it are. Results further show that the patterns of the discussion in the two countries studied bore a remarkable resemblance at a general level, whereas there are indications of differences in the driving forces behind suggestions for similar reforms in these two countries.

An analysis of the revenue policy -making process of the Texas Legislature

The purpose of this dissertation was to develop a conceptual framework which can be used to account for policy decisions made by the House Ways and Means Committee (HW&MC) of the Texas House of Representatives. This analysis will examine the actions of the committee over a ten-year period with the goal of explaining and predicting the success of failure of certain efforts to raise revenue.^ The basis framework for modelling the revenue decision-making process includes three major components--the decision alternatives, the external factors and two competing contingency theories. The decision alternatives encompass the particular options available to increase tax revenue. The options were classified as non-innovative or innovative. The non-innovative options included the sales, franchise, property and severance taxes. The innovative options were principally the personal and corporate income taxes.^ The external factors included political and economic constraints that affected the actions of the HW&MC. Several key political constraints on committee decision-making were addressed--including public attitudes, interest groups, political party strength and tradition and precedents. The economic constraints that affected revenue decisions included court mandates, federal mandates and the fiscal condition of the nation and the state.^ The third component of the revenue decision-making framework included two alternative contingency theories. The first alternative theory postulated that the committee structure, including the individual member roles and the overall committee style, resulted in distinctive revenue decisions. This theory will be favored if evidence points to the committee acting autonomously with less concern for the policies of the Speaker of the House. The Speaker assignment theory, postulated that the assignment of committee members shaped or changed the course of committee decision-making. This theory will be favored if there was evidence that the committee was strictly a vehicle for the Speaker to institute his preferred tax policies.^ The ultimate goal of this analysis is to develop an explanation for legislative decision-making about tax policy. This explanation will be based on the linkages across various tax options, political and economic constraints, member roles and committee style and the patterns of committee assignment. ^

Farmers behaviour on mitigation and adaptation to climate change: A case study in Kenya.

Farmers in Africa are facing climate change and challenging rural livelihoods while maintaining agricultural systems that are not resilient. By 2050 the mean estimates of production of key staple crops in Africa such as maize, sorghum, millet, groundnut, and cassava are expected to decrease by between 8 and 22 percent (Schlenker and Lobell 2010). In Kenya, although projections of rainfall do not show dramatic decreases, the distribution of impacts is clearly negative for most crops. As increases in temperature will lead to increases in evapotranspiration, a potential increase in rainfall in Kenya may not offset the expected increases in agricultural water needs (Herrero et al. 2010). In order to respond to these present and future challenges, potential mitigation and adaptation options have been developed. However, implementation is not evident. In addition to their benefits in either mitigating or reducing the vulnerability of climate change effects, many of these options do not have economic costs and even provide economic benefits (e.g. savings in the consumption of energy or natural resources). Nevertheless, it is demonstrated that even when there are no biophysical, technological or economic constraints and despite their potential benefits from either the economic or environmental climate change point of view, not all farmers are willing to adopt these measures. This reflects the key role that behavioural barriers can play in the uptake of mitigation and adaptation measures.

Evolução da capacidade de regularização do sistema hidrelétrico brasileiro.

No Brasil, cerca de dois terços da capacidade total instalada de geração de energia elétrica e, em média nos últimos quinze anos, aproximadamente 90% da geração efetiva provêm das hidrelétricas. Este sistema inclui 170 usinas hidrelétricas de médio e grande porte existentes ou previstas até 2023, aproximadamente dois terços delas com capacidade de regularizar vazões e todas operando de maneira interligada. Restrições ambientais, técnicas, sociais e econômicas tem dificultado cada vez mais a implantação de empreendimentos hidráulicos contendo reservatórios de grande porte, tornando a maioria dos novos empreendimentos a fio d´água. Para compreender melhor o processo, este trabalho apresenta um levantamento da evolução anual da capacidade instalada e de armazenamento do sistema desde 1950 até a expansão prevista nos próximos 8 anos, em 2023. Os dados da década de 2000 e a previsão até 2023 de forma ainda mais acentuada indicam uma redução continua e significativa da capacidade relativa de regularização, com impacto direto nas decisões de operação e de expansão do sistema térmico complementar. A fim de avaliar as possíveis consequências da redução da capacidade de regularização, simulações foram realizadas no modelo HIDROTERM (ZAMBON et al. 2012); os resultados apontam para uma necessidade de ser complementar continuamente a energia hídrica, não só em períodos hidrologicamente desfavoráveis.

An evaluation of a telephone-based postnatal support intervention for infant feeding in a regional Australian city

Background: Postnatal breastfeeding support in the form of home visits is difficult to accommodate in regional Australia, where hospitals often deal with harsh economic constraints in a context where they are required to provide services to geographically, dispersed consumers. This study evaluated a predominately telephone-based support service called the Infant Feeding Support Service. Methods: A prospective cohort design was used to compare data for 696 women giving birth in two regional hospitals (one public, one private) and participating in the support service between January and July 2003 with data from a cohort of 625 women who gave birth in those hospitals before the introduction of the support service. Each mother participating in the support service was assigned a lactation consultant. First contact occurred 48 hours after discharge, and approximately it weekly thereafter for 4 it weeks. Breastfeeding duration was measured at 3 months postpartum. Results: For women from the private hospital, the support service improved exclusive breastfeeding duration to 4.5 weeks postpartum, but these improvements were not evident at 3 months postpartum. No effects were observed for mothers from the public hospital. Quantitative and qualitative data demonstrated high levels of client satisfaction with the support service. Conclusions: This small-scale, predominately telephone-based intervention provided significant, although apparently context-sensitive, improvements to exclusive breastfeeding duration.

Transplanting Anglo-American accounting oversight boards to a diverse institutional context

The introduction of accounting and auditing oversight boards (OBs) has been promoted on a global scale as a key component of the international financial architecture that has emerged over the past two decades. Such institutions, modeled on the Anglo-American tradition, are domestically organized and embedded within distinctively diverse institutional contexts. Their role is to ease agency problems, improve the quality of financial reporting, and help provide stability in the global financial system. We employ an institutional approach, located within the broader political economy framework of global capitalism, to examine the establishment and operation of the new regulatory regime in Greece. Greece, a member of the European Union, exhibits characteristics of a "delegative" democracy, i.e. a traditionally weak institutionalization, reform (in)capacity problems and a clientelistic political system. Our case study shows that the formation and operation of the newly-established system of oversight is conditioned by local political and economic constraints and, thus, does not automatically translate into concrete benefits for the quality of financial reporting. We also draw attention to the structural mismatch between a progressing globalized financial integration and the fragmented nature of the system of oversight, and illustrate that OBs' independence from local governments is an important but neglected issue.

Minority enterprise in the clothing industry: an analysis of Asian jeans manufacturers in Birmingham

This thesis discusses and assesses the resources available to Asian entrepreneurs in the West Midlands' clothing industry and how they are used by these small businessmen in order to address opportunities in the market economy within the constraints imposed. The fashion industry is volatile and is dependent upon flexible firms which can respond quickly to shortrun production schedules. Small firms are best able to respond to this market environment. Production of jeans presents an interesting departure from the mainstream fashion industry. It is traditionally gared towards longrun production schedules where multinational enterprises have artificially diversified the market, promoting the 'right' brand name and have established control of the upper end of the market, whilst imports from Newly Developing Countries have catered for cheap copies at the lower end of the market. In recent years, a fashion element to jeans has emerged, thus opening a market gap for U.K. manufacturers to respond in the same way as for other fashion articles. A large immigrant population, previously serving the now declining factories and foundries of the West Midlands but, through redundancy, no longer a part of this employment sector, has ~5ponded to economic constraints and market opportunities by drawing on ethnic network resources for competitive access to labour, finance and contacts, to attack the emergent market gap. Two models of these Asian entrepreneurs are developed. One being somecne who has professionally and actively tackled the market gap and become established. These entrepreneurs are usually educated and have personal experience in business and were amongst the first to perceive opportunities to enter the industry, actively utilising their ethnicity as a resource upon which to draw for favorable access to cheap, flexible labour and capital. The second model is composed of later entrants to jeans manufacturing. They have less formal education and experience and have been pushed into self-employment by constraints of unemployment. Their ethnicity is passively used as a resource. They are more likely confined to the marginal activity of 'cut make and trim' and have little opportunity to increase profit margins, become estalished or expand.

Developing brownfields ranking models using decision analytic methods

The redevelopment of Brownfields has taken off in the 1990s, supported by federal and state incentives, and largely accomplished by local initiatives. Brownfields redevelopment has several associated benefits. These include the revitalization of inner-city neighborhoods, creation of jobs, stimulation of tax revenues, greater protection of public health and natural resources, the renewal and reuse existing civil infrastructure and Greenfields protection. While these benefits are numerous, the obstacles to Brownfields redevelopment are also very much alive. Redevelopment issues typically embrace a host of financial and legal liability concerns, technical and economic constraints, competing objectives, and uncertainties arising from inadequate site information. Because the resources for Brownfields redevelopment are usually limited, local programs will require creativity in addressing these existing obstacles in a manner that extends their limited resources for returning Brownfields to productive uses. Such programs may benefit from a structured and defensible decision framework to prioritize sites for redevelopment: one that incorporates the desired objectives, corresponding variables and uncertainties associated with Brownfields redevelopment. This thesis demonstrates the use of a decision analytic tool, Bayesian Influence Diagrams, and related decision analytic tools in developing quantitative decision models to evaluate and rank Brownfields sites on the basis of their redevelopment potential.

Factors contributing to defaulting scheduled therapy sessions by caregivers of children with congenital disabilities

Background Defaulting scheduled rehabilitation therapy may result in increased adverse outcomes such as permanent disability and increased healthcare costs. Concomitantly, there is evidence to suggest that early and continued rehabilitation of children with congenital disabilities can improve outcomes significantly. This study was conducted to determine factors contributing to caregivers’ defaulting scheduled rehabilitation therapy sessions. Methods A descriptive cross sectional study was carried out at Chitungwiza Central Hospital, a tertiary facility offering in and outpatient rehabilitation services in Zimbabwe. Caregivers of children who had congenital disabilities (N=40) and who had a history of defaulting treatment but were available during the data collection period responded to an interviewer administered questionnaire. Data were analysed for means and frequencies using STATA 13. Results Factors that contributed to caregivers defaulting scheduled therapy included economic constraints (52%), child related factors (43%), caregiver related factors (42%), service centred factors (30%) and psychosocial factors (58%). Majority of the caregivers (98%) were motivated to attend therapy by observable improvements in their children. Other motivators were incentives given in the rehabilitation department (45%), availability of rehabilitation personnel to provide the required services (48%) and psychosocial support from fellow caregivers, families and the rehabilitation staff (68%). Although all the caregivers could not distinguish occupational therapy from physiotherapy services they all reported that therapy was important. Conclusions A combination of psychosocial, economic, child centred and service centred factors contributed to caregivers defaulting scheduled therapy. Interventions that may potentially improve caregiver attendance to scheduled therapy include community outreach services, efficient rehabilitation service provision at the hospitals, and facilitation of income generating programmes for caregivers.
