Assessing the economics of auto recycling activities in relation to European Union Directive on end of life vehicles

Technical requirements for car design and minimum reuse and recovery rates for end-of-life vehicles (ELV) are the subject of a new EU Directive on ELV. This Directive is expected to induce changes in the infrastructures required for ELV processing, and presents a challenge to maintain such economically viable infrastructure.Technical-cost models of ELV processing operators were developed to interpret the changing economics of auto recycling activities under the new EU Directive on ELV.The results obtained show that the recycling targets defined in the EU Directive for 2006, require the removal of an increased number of plastic parts from an ELV. In particular, removing up to 14% of the ELV mass results in a recycling rate over 80%, even for vehicles with a ferrous content up to about 65%. These operations can be performed economically by dismantlers, provided that they may get a steady flow of ELV hulks, free of charge, and that the international quotation for steel scrap does not come significantly below 120 €/ton.In the long term, developing separation technologies for automotive shredder residues and finding recycling possibilities for the products gained from the separation, might be a valuable scenario to meet the 2015 recycling quotas.     

Discussing the political survival of Romanian ministers since 1989—Do economic conditions matter?

Political longevity in young democracies has attracted the attention of scholars and practitioners alike due to several particular characteristics of such democracies, such as a low level of trust, a low level of credibility, corruption, economic difficulties, a less well‐established rule of law and an increased bureaucracy. In such a context, we studied the tenure duration of Romanian ministers since 1989, as well as their accumulated political longevity in ministerial offices. Using proportional hazards regression, we observed some peculiarities in the young Romanian democracy in comparison with more established regimes. We observed that left‐wing majorities tend to increase the probability of seat changes and thus diminish tenure longevity. We also observed that good economic conditions may lead to the substitution of certain types of ministries, while higher inflation rates tend to shorten tenure longevity for Romanian ministers. Moreover, our estimations support the finding that Romanian ministers tend to have shorter tenures as the number of past ministerial functions increases and that the burden of simultaneously managing various ministries significantly contributes to the shorter political longevity of a given minister. Finally, recent ministers have had longer tenures than those in the first years after the fall of communism in Eastern Europe in 1989.

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.

Main difficulties during RFID implementation: an exploratory factor analysis approach

RFID (Radio Frequency Identification) systems are meant to increase accuracy and velocity in objects identification, supporting Industry 4.0. However, there are challenges that need to be faced. This paper aims to identify and analyse the main difficulties regarding RFID systems implementation. We combined both systematic literature review and survey methods with ninety RFID experts. Data was analysed through Exploratory Factor Analysis. Empirical evidences have led to three main factors explaining most of the variance: operational difficulties, planning difficulties and employee difficulties. This corroborates the literature with recent data sets and provides quantitative analysis for prioritisation during RFID implementation. Professionals can use these research results as a guide to RFID systems implementation to create preventive actions during implementation initiatives. In the context of the Internet of Things and Fourth Industrial Revolution, RFID is considered an emerging topic nowadays, but no similar studies exist in the scientific literature.
