EUROPEAN PLANNING STUDIES
Abstract
Although there is a considerable amount of empirical evidence on inter-firm collaborations within technology-based industries, there are only a few works focussing on R&D cooperation by low-tech firms, especially small and medium-sized enterprises (SMEs). Providing further and new evidence based on a recently built database of CRAFT projects, this study analyses the relationship between technology and proximity in international R&D networks using HOMALS and statistical cluster techniques. The resulting typology of international cooperative R&D projects highlights that successful international cooperative R&D projects are both culturally/geographically closer and distant. Moreover, and quite interestingly, geographically distant projects are technologically more advanced whereas those located near each other are essentially low-tech. Such evidence is likely to reflect the tacit-codified knowledge debate boosted recently by the information and communication technology (ICT) "revolution" emphasized by the prophets of the "Death of Distance" and the "End of Geography".

JOURNAL OF EVOLUTIONARY ECONOMICS
Abstract
In the last two decades, there has been a noticeable increase in published research on evolutionary economics. The general perception is that formalization lags behind appreciative work. Notwithstanding, this general reading has yet to be supported by real data analysis. This work presents a survey on evolutionary economics, aimed at exploring the main research paths and contributions using bibliometric methods. The documentation is based on an extensive review of the abstracts from articles published in all economic journals over the past 50 years gathered from the Econlit database. Evolutionary contributions have apparently not converged to an integrated approach. Two rather extreme main research strands emerged: 'History of Economic Thought and Methodology' and 'Games'. Whereas formal approaches have a reasonable and increasing share of published papers, purely empirical-related works are relatively scarce, representing a meagre and stagnant percentage of published works. This highlights the need to redirect the evolutionary research agenda.

RESEARCH POLICY
Abstract
An important characteristic of the role of foreign trade in the technological catch-up of countries is the complementary nature with technological change, human capital development and local R&D efforts. Using cointegration techniques, evidence based on Portuguese long-run growth suggests that by investing in certain capacity-building activities, namely human capital and local R&D efforts, countries can improve their ability to identify, value, assimilate, and apply (or exploit) knowledge that is developed in other (more developed) countries. Although human capital has a stronger direct impact on total factor productivity than internal R&D efforts, the latter's indirect impact, by means of machinery and equipment imports, is tremendous. Trade also emerges as a powerful direct contributor to long-term total factor productivity, especially in its embodied form, through the acquisition of advanced machinery and equipment from more developed countries. The (smaller) productivity enhancing effect of licenses and FDI seems to be strongly dependent on institutional circumstances, namely those related to human capital investments and incentives.

HIGHER EDUCATION
Abstract
Today's economics and business students are expected to be our future business people and potentially the economic leaders and politicians of tomorrow. Thus, their beliefs and practices are liable to affect the definition of acceptable economics and business ethics. The empirical evaluation of the phenomenon of cheating in academia has almost exclusively focused on the US context, and non-US studies usually only cover a narrow range of countries. This paper presents a comprehensive, cross-country study on the magnitude and determinants of cheating among economics and business undergraduates, involving 7,213 students enrolled in 42 universities located in 21 countries from the American (4), European (14), Africa (2) and Oceania (1) Continents. We found that the average magnitude of copying among economics and business undergraduates is quite high (62%) but there was significant cross-country heterogeneity. The probability of cheating is significantly lower in students enrolled in schools located in the Scandinavian, and the US and British Isles blocks when compared with their Southern European counterparts; quite surprisingly this probability is also lower for the African block. On a distinctly different level, however, students enrolled in schools in Western and especially Eastern European countries reveal statistically significant higher propensities towards committing academic fraud.

SCIENTOMETRICS
Abstract
Although there is considerable consensus that Finance, Management and Marketing are 'science', some debate remains with regard to whether these three areas comprise autonomous, organized and settled scientific fields of research. In this paper we aim to explore this issue by analyzing the occurrence of citations in the top-ranked journals in the areas of Finance, Management, and Marketing. We put forward a modified version of the model of science as a network, proposed by Klamer and Van Dalen (J Econ Methodol 9(2):289-315, 2002), and conclude that Finance is a 'Relatively autonomous, organized and settled field of research', whereas Management and (to a larger extent) Marketing are relatively non-autonomous and hybrid fields of research'. Complementary analysis based on sub-discipline rankings using the recursive methodology of Liebowitz and Palmer (J Econ Lit 22:77-88, 1984) confirms the results. In conclusions we briefly discuss the pertinence of Whitley's (The intellectual and social organization of the sciences, 1984) theory for explaining cultural differences across these sub-disciplines based on its dimensions of scholarly practices, 'mutual dependency' and 'task uncertainty'.

ECOLOGICAL ECONOMICS
Abstract
In ecological economics the debate on formalism and formalization has been addressed in the context of a lively discussion on ecological economics as a 'post-normal' (versus 'normal') science. Using ecological economics (EE) as a 'seed' journal and applying bibliometric techniques to all (2533) the articles published in EE from January 1989 to December 2009, we analyze the evolution of the field of ecological economics aiming to shed light on this debate. We observe the predominance (and increased relevance) of certain research topics: 'Methodological issues', 'Policies, governance and institutions' and 'Valuation'. Moreover, 'Collective action', 'Technical change and the environment' and 'Values' stand as emergent themes of research. Finally, we note that ecological economics experienced an 'empirical turn' reflected in a shift away from exclusively formalized papers towards exclusively empirical and, to a larger extent, 'formal and empirical' ones. The combination of the prominent and emergent topics and the 'empirical turn' mirrors the increasing awareness among researchers in the field of the need to address a key specificity of ecological economics - the interdependence of the economic, biophysical and social spheres. On this basis, we argue that at least through the lens of EE, ecological economics has evolved towards a post-normal science.
