Sedimentological and archaeological fabrics in Palaeolithic levels of the South-Eastern Pyrenees: Cova Gran and Roca dels Bous Sites (Lleida, Spain)

The comparative study of sedimentary fabrics in relation to archaeological fabrics in various levels of the sites of Cova Gran de Santa Linya (Middle and Early Upper Palaeolithic) and the Roca dels Bous (Middle Palaeolithic) has made it possible to analyse the formation dynamics of the deposits and determine the extent of disturbance of the archaeological levels by natural processes. To achieve this, diagrams and two- and three-dimensional indices were calculated from the azimuth and dip angle of natural clasts and artefacts. The results indicate that the sedimentary levels were formed mainly by planar fabric shape gravitational processes (low depositional angles), which differ notably from the archaeological fabrics they contain, characterised by a greater degree of isotropy. This difference in the fabrics would reflect human activity and indicates that the archaeological levels both in Cova Gran and Roca dels Bous have not been subject to significant natural modifications, and are preserved in situ.     

Environmental Regulations and Multinational Corporations' Foreign Market Entry Investments

In this study, we examine how differences in environmental regulation characteristics are linked to multinational corporations' (MNCs) foreign market entry (FME) investments decisions around the world. We rely on a data set with 29,303 observations from 94 European Fortune Global 500 companies operating across 77 countries during the period 2001–2007. We found that MNCs are more likely to enter countries with more certain—i.e., clearer and more stable—environmental regulations than those of their home countries. Results also suggest that there is a higher level of MNC entry into foreign countries with environmental regulations that are more stringent than those of their home countries. This finding challenges the controversial but commonly held view that more stringent environmental regulations deter MNCs' FME investments. Notably, the magnitude of the regulatory certainty relationship with MNCs' FME investments is larger than that of regulatory stringency. Findings also indicate that the increased tendency of MNCs to enter countries with more stringent environmental regulations is higher in more democratic countries and for cleaner industry firms.     

A Place for Everyone. The Structure of Arroyo Culebro D Cemetery and The Social Organization in the Middle Tagus Valley Iron Age (Spain)

The relationship between agriculture, sedentarization and the emergence of inequality has been a common subject when analysing the transition between egalitarian and non‐egalitarian societies. However, the strategies used during that process and their archaeological expressions are difficult to detect and interpret. The aim of this paper is to provide an example – the emergence of Early Iron Age cremation cemeteries in the Middle Tagus valley – of how this transformation could have been materially expressed. Through the study of Arroyo Culebro D and other cremation cemeteries, we will analyse the crucial moment when the structural changes that sedentarization carries started to be ideologically assumed, expressed and (or) repressed.     

Are Members of Business for Social Responsibility More Socially Responsible?

This study examines the association between corporate social performance (CSP) practices and membership in Business for Social Responsibility (BSR) between 1992 and 2006. BSR is a business association that seeks to help its members adopt enhanced CSP practices. While there is an emerging literature examining voluntary initiatives as alternative policy mechanisms to regulations, most research is focused on initiatives that emphasize environmental protection. Further, studies suggest that membership in strictly voluntary initiatives tends to be associated with lower environmental performance because of “free‐riding” behavior by participants. BSR differs along two dimensions when compared with other voluntary initiatives examined in the literature. First, it is a comprehensive voluntary social initiative that helps firms from diverse industries address multiple CSP issues simultaneously. Second, it might limit opportunism by not offering blanket certification to its participants. Our results indicate that BSR members exhibit greater levels of positive social impacts without demonstrating significantly different levels of negative social impacts. This suggests that participation in voluntary initiatives that avoid granting blanket certifications may be associated with the adoption of new corporate social responsibility practices but not linked to the shedding of entrenched routines that produce negative externalities.     

Palaeolithic engravings and sedimentary environments in the Côa River Valley (Portugal): implications for the detection,interpretation and dating of open-air rock art

The pre-Magdalenian phase of the Côa River Valley open-air rock art is mostly distributed at the boundary between the rocky valley slopes and the floodplain that correspond to the most favourable geomorphological setting for the preservation of pecked and deeply superposed engravings of the most famous artistic phase of the area. The natural vertical panels of the engraved art located at this geomorphological interface have suffered weathering during two cold events of the Lateglacial. They were buried by several colluvial and alluvial deposits. The reconstruction of the sedimentary and archaeological context of the CôaRiver Valley engraving permits a better assessment of the preservation processes and interpretation of Palaeolithic open-air rock art.     

Is Greener Whiter Yet? The Sustainable Slopes Program after Five Years

This study focuses on two basic questions: Are voluntary programs effective in promoting higher environmental performance by participant firms? If so, which distinct areas of environmental performance are more likely to be improved by firms joining a voluntary environmental program? We address these questions by assessing the environmental effectiveness of the ski industry’s Sustainable Slopes Program in the western United States between 2001 and 2005. We found no evidence in our five-year analysis to conclude that ski areas adopting the SSP displayed superior performance levels than nonparticipants for the following areas of environmental protection: overall environmental performance, expansion management, pollution management, and wildlife and habitat management. SSP participants only appear to show a statistically significant correlation with higher natural resource conservation performance rates. For policymakers, these results suggest that caution is needed before a priori assuming that strictly voluntary programs can be effective in promoting comprehensive superior environmental performance.
