Sustainability and Food: a Text Analysis of the Scientific Literature

The paper analyses the evolution of the research debate related to sustainability and to the relation between food and sustainability. A number of text analysis techniques were combined for the investigation of scientific papers. The results stress how discourse analysis of sustainability in the pre-Rio period is mostly associated with agriculture and with a vision where the ecological and environmental aspects are dominant. In the post-Rio phase, the discussion about sustainability, though still strongly linked to environmental issues, enters a holistic dimension that includes social elements. The themes of energy and the sustainability of urban areas become central, and the scientific debate stresses the importance of indicators within an assessment approach linked to the relevance of planning and intervention aspects. The focus on the role of food within the debate on sustainability highlights a food security oriented approach in the pre-Rio phase, with a particular attention towards agriculture and third world Countries. In the post-Rio period, the focus of the analysis moves towards developed Countries. Even though food security remains a strongly significant element of the debate, the attention shifts towards consumers and food choices

The atmospheric effects of stratospheric aircraft. Report of the 1992 Models and Measurements Workshop. Volume 1: Workshop objectives and summary

This Workshop on Stratospheric Models and Measurements (M&M) marks a significant expansion in the history of model intercomparisons. It provides a foundation for establishing the credibility of stratospheric models used in environmental assessments of chlorofluorocarbons, aircraft emissions, and climate-chemistry interactions. The core of the M&M comparisons involves the selection of observations of the current stratosphere (i.e., within the last 15 years): these data are believed to be accurate and representative of certain aspects of stratospheric chemistry and dynamics that the models should be able to simulate

Adult education in small states : the case of Malta

A small state faces several challenges with regard to adult continuing education and training. The paper discusses some of these challenges with specific reference to the Mediterranean small island state of Malta. It starts with a general discussion of some of the issues affecting adult education in a small state such as Malta that paves the way for the more focused analyses in the second and third sections. These sections focus on a selection of just two topics from among the many that affect adult education in Malta, namely those of adult education and work and adult education for sustainable development. These analyses are tackled from the perspective of the small state condition.peer-reviewe

The Transatlantic Productivity Gap: Is R&D the Main Culprit?

The literature has pointed to different causes to explain the productivity gap between Europe and United States in the last decades. This paper tests the hypothesis that the lower European productivity performance in comparison with the US can be explained not only by a lower level of corporate R&D investment, but also by a lower capacity to translate R&D investment into productivity gains. The proposed microeconometric estimates are based on a unique longitudinal database covering the period 1990-2008 and comprising 1,809 US and European companies for a total of 16,079 observations. Consistent with previous literature, we find robust evidence of a significant impact of R&D on productivity; however – using different estimation techniques – the R&D coefficients for the US firms always turn out to be significantly higher. To see to what extent these transatlantic differences may be related to the different sectoral structures in the US and the EU, we differentiated the analysis by sectors. The result is that both in manufacturing, services and high-tech sectors US firms are more efficient in translating their R&D investments into productivity increases.R&D, productivity, embodied technological change, US, EU

CURRENT ISSUES AFFECTING TRADE AND TRADE POLICY: AN ANNOTATED LITERATURE REVIEW

This review provides a base of literature describing current issues and research on the impacts of lobalization and the industrialization of agriculture and recent approaches to analyze and model agricultural trade and trade policies. Three key factors of the survey are differentiated goods, global economic integration and international supply chain linkages. The review covers 182 publications, which are presented alphabetically by author with a brief annotation describing how it relates to the above criteria. The articles are also indexed by keyword. A brief summary highlights the documented literature and includes a series of issues for future discussion and research.International Relations/Trade,

The construction of valued skills and expertise within the IT profession: continuing tensions between techies and managers

The research investigates the expertise, skills and attributes of computer specialists. In particular, it focuses on managers' construction of certain attributes of computer professionals as valuable. In other words it asks "what makes a computer professional valuable?" Although this is of interest in itself, it is also a vehicle for investigating the computing occupation more widely. As the research deals with meaning and sense-making, context is all important. Consequently, the context within which the computing occupation and the skills within it are situated are a major theme throughout. This study consists of semi-structured interviews with IT managers and some user and personnel managers. The analysis of the interview data revealed two different organisational types: IT companies and IT departments. The managers within computer departments and companies constructed value differently and as career and employment environments these organisations appeared to offer different opportunities.

Working Across Boundaries: Current and Future Perspectives on Global Virtual Teams

Global Virtual Teams (GVTs) are a commonplace in contemporary organizations, and an already established topic of research in international management. While we have a good understanding of advantages and challenges associated with this ubiquitous form of work groups, this special issue aims to contribute to theory development by focusing on key drivers that influence the success of GVTs, along with ways for mitigating their challenges. We briefly review current knowledge on GVTs and propose a structuring framework that can help with both organizing what we know about GVTs, and with guiding the conversation on where the research on this topic might focus next. We then introduce four special issue articles that illustrate avenues for generating new empirical evidence towards uncovering key characteristics and dynamics underlying GVTs complexities, providing useful insights for both theory development and managerial practice
