Assessing changes in teachers’ attitudes toward interdisciplinary STEM teaching

Integrating engineering and technology concepts into K-12 science and math curricula through engineering design project-based learning has been found to increase students’ interest in science, technology, engineering, and mathematics (STEM), however preparing teachers to shift to interdisciplinary teaching remains a significant challenge. Primarily teachers need to develop both skills and attitudes toward interdisciplinary teaching. In doing so, professional development (PD) is considered a key component in helping teachers through this transformation process. In an educational environment of accountability, measuring the effects of PD programs on teacher behaviors and capacity is essential but often elusive. The current study describes the change in attitudes to interdisciplinary teaching of 29 self-selected middle and high school teachers who participated a PD workshop and in delivering a 12–15 week interdisciplinary teaching and design problem unit that spanned multiple STEM subjects. This quasi-experimental pilot study implemented a single group pretest–posttest design using survey methods to collect data from the participants at two intervals; at the time of the PD workshop and at the completion of the teaching unit that emphasized a long-term engineering design problem. The goals of this research are to (1) assess the changes in attitudes to interdisciplinary teaching, attitudes to teamwork, teaching satisfaction, and resistance to change, (2) explore relationships among these changes, (3) and describe the variation in these changes across teachers’ gender, school level, discipline taught, and education level.     

Urban food markets and their sustainability: the compatibility of traditional and tourist uses

The aim of this article is to highlight the importance of urban food markets as tourist icons in the current competitive race to create attractive cities. Food markets attract a large number of consumers, both local and tourists. However, their impact on the city and its dynamics should be treated to establish measures to ensure sustainable (compatible) uses for both kinds of users. This calls for the establishment of a system of indicators to determine what level of sustainability food markets are at and facilitate decision-making for the agents involved in their management.     

Smarter through social protection? Evaluating the impact of Ethiopia’s safety-net on child cognitive abilities

Ethiopia’s productive safety net is the second largest Social Protection Program in sub-Saharan Africa and has been rolled out to almost 10 million beneficiaries since 2005; its effects are therefore of general interest. We provide the first estimates of its impact on children’s cognitive abilities. To identify impacts of this program, we exploit four rounds of data on a cohort of children surveyed repeatedly between 2002 and 2013. We find a small but significant positive effect of the programme on both numeracy skills and vocabulary. This is driven mainly by children in households that had graduated (left) the programme just before 2013. We argue that this is at least partially related to time allocation: graduates of the programme spent more time in school than continuing beneficiaries. We also find evidence that the maths (though not language) improvement is more pronounced for boys.     

Poverty changes in Manaus: Legacy of a Brazilian free trade zone?

This study contributes to the literature on the social impacts of Special Economic Zones by analyzing poverty changes in the Brazilian state of Amazonas, where the Free Trade Zone of Manaus (FTZM) is located. Using census data, statistical micro‐decompositions and counterfactual simulations, we show that labor income was the major driver of poverty declines during the 2000 to 2010 decade in the municipality of Manaus (and all the more so for households with members working in the FTZM, who were less poor to start with). Comparison with ex‐ante “similar” municipalities, in regard to socioeconomic and demographic criteria, corroborates the relative success of Manaus in terms of poverty reduction as well as the essential role played by labor income. Wage regressions also show a significant FTZM premium effect for workers, though diminishing over time. In the rest of the state of Amazonas, nonlabor income remains the main factor for poverty reduction and the FTZM appears to have limited spillover effects, even at short distances. Our contrasting results illustrate both the benefits and limitations that trade and industrial policies face in underprivileged areas and suggest that a better targeting of social policies is needed to improve distributional outcomes and spillovers for the whole state.     

Warehouse receipt financing for smallholders in developing countries: Challenges and limitations

A warehouse receipt is a document issued by a warehouse operator as evidence that a specified commodity of stated quantity and quality has been deposited at a particular warehouse by a named depositor. When backed by an appropriate legal and regulatory framework, a warehouse receipt becomes a formal financial instrument that allows the depositor to confer a security interest in the stored commodity to another party without requiring physical delivery, allowing the warehouse receipt to serve as possessory collateral for a loan. Warehouse receipt financing, in theory, permits smallholders farmers in developing countries to store their surplus safely in a modern warehouse to sell at a later date when prices are higher, while allowing them to use the stored commodity as collateral to secure a loan to finance household consumption and investment needs in the interim. However, in practice, warehouse receipt financing generally has not been embraced by smallholders in developing countries in which it is available. Here, we develop and analyze a formal stochastic dynamic model of seasonal commodity marketing that exposes the transaction cost and risk reallocation problems that undermine the benefits of warehouse receipt financing to smallholders.     

The transformative and emancipatory potential of participatory evaluation: reflections from a participatory action research study with war-affected young mothers

The Participatory Action Research (PAR) study with Young Mothers in Liberia, Sierra Leone and northern Uganda which took place from 2006 to 2009 aimed to understand what ‘reintegration’ meant to young mothers formerly associated with armed groups. It also implemented social action initiatives designed by study participants to promote their wellbeing and achieve reintegration. We evaluated the study using multiple participatory evaluation methods, situating evaluation as part of the cycle of research and action. This approach facilitated young mothers’ participation in developing the criteria by which the study and its reintegration outcomes would be judged. We describe each method and what we uniquely learned from using a participatory evaluation approach. We discuss how this approach is well-suited for complex studies, can enhance data quality, increases capacity of all involved in the evaluation and supports the critical reflexivity necessary for participatory studies to succeed.

Integrating embeddedness with dynamic capabilities in the internationalisation of fashion retailers

The paper presents an integration of the theoretical approaches of embeddedness and dynamic capabilities. Based on in-depth interviews with key informants of international fashion retail companies we show that dynamic capabilities enhance different types of embeddedness at different levels. Generic dynamic capabilities of adaptability and knowledge management play a role as they affect retailer-specific capabilities and societal, network and territorial forms of embeddedness. Integrating the two theoretical approaches provides new and deeper understanding of the nature of retail internationalization.     

Determinants of obesity in Brazil: the effects of trade liberalization and socio-economic variables

This article aims to evaluate a possible relation between increased Brazilian trade openness and increasing observed rates of overweight and obesity during the last 25 years. We develop an economic model where formal trade barriers are eliminated, and resulting sociocultural outcomes such as the adoption of westernized lifestyle in traditional non-western countries prevails, which could imply a health externality. In order to empirically analyse the influence of trade flows on overweight and obesity in Brazil, a balanced fixed-effects panel model has been estimated. Data for the 26 Brazilian states plus the Federal District are run for 1988/1989, 2002 and 2008. We found that an increase in trade openness leads to an increase in overweight and obesity ratios in Brazil. Hence results seem to point that there is a health externality in Brazil due to trade liberalization. However, more consistent evidence may be necessary to convince politicians and policymakers that any interference will be necessary to correct this externality.     

Sustainable development in small and medium enterprises: The role of entrepreneurial orientation in supply chain management

Organizations are under increased pressure to improve their sustainable performance through the adoption of green supply chain management (GSCM) practices. Small and medium enterprises (SMEs) have lagged behind larger corporations due to a number of factors. Chief among these factors is the lack of resources and capabilities. In this study, we investigate whether entrepreneurial orientation as a distinctive firm-level resource contributes to the successful implementation of GSCM practices within SMEs. We use primary data obtained from 316 manufacturing SMEs and analyze the data by using a fuzzy-set qualitative comparative analysis (fsQCA). Our findings show four equifinal configurations of GSCM practices and the components of entrepreneurial orientation (EO) that lead to high environmental performance. Two practices, “eco-design” and “internal environmental management”, are present in all configurations, with the latter being the single core condition. The components of EO are present in all the configurations. Three distinct configurations lead to the simultaneous achievement of high environmental performance and high economic performance. Some noticeable differences appear in these configurations: “internal environmental management” is no longer a core condition, instead external practices (“green purchasing,” “cooperation with customers including environmental requirements,” and “investment recovery”) and “risk-taking” become core conditions. We exptrapolate our findings into a set of propositions that expand theory on the link between entrepreneurial orientation and sustainable performance. Our study provides insights for managers who seek to infuse entrepreneurial thoughts and actions into their green supply chain initiatives.
