The sustainable use of common-pool resources depends on users’ behaviour with regards to appropriation and provision. Most knowledge about behaviour in such situations comes from experimental research. As experiments take place in confined environments, motivational drivers and actions in the field might differ. This paper analyses farmers’ use of common property pastures in Grindelwald, Switzerland. Binary logistic regression is applied to survey data to explore the effect of farmers’ attributes on livestock endowment, appropriation and provision behaviour. Furthermore, Q methodology is used to assess the impact of broader contextual variables on the sustainability of common property pastures. It is shown that the strongest associations exist between (a) socio-economic attributes and change in livestock endowment; (b) norms and appropriation behaviour; and (c) area and pay-off and provision behaviour. Relevant contextual variables are the economic value of the resource units, off-farm income opportunities, and the subsidy structure. We conclude that with increasing farm size farmers reduce the use and maintenance of common property. Additionally, we postulate that readiness to maintain a resource increases with appropriation activities and the net returns generated from appropriation.

This study was an exploratory investigation of variables which are associated with neonatal intensive care nurses' perceptions of and participation in life-sustaining treatment decisions for critically ill newborns. The primary purpose of the research was to examine the extent to which assessment of infants' physical and mental prognoses, parents' preferences regarding treatment, and legal consequences of non-treatment influence nurses' recommendations about life-saving treatment decisions for handicapped newborns. Secondly, the research explored the extent and nature of nurses' reported participation in the resolution of treatment dilemmas for these critically ill newborns. The framework of the study draws upon the work of Crane (1977), Blum (1980), and Pearlman (1982) who have explored the sociological context of decision-making with critical care patients.^ Participants in the study were a volunteer sample of eighty-three registered nurses who were currently working in neonatal intensive care units in five large urban hospitals in Texas. Data were collected through the use of intensive interviews and case study questionnaires. Results from the study indicate that physical and mental prognoses as well as parent preferences and concerns about legal liability are related to nurses' treatment recommendations, but their levels of significance vary according to the type of handicapping condition and whether the treatment questions are posed in terms of initiating aggressive therapy or withdrawing aggressive therapy.^ The majority of nurses reported that the extent of their participation in formal decision-making regarding handicapped newborns was fairly minimal although they provide much of the definitive data used to make decisions by physicians and parents. There was substantial evidence that nurse respondents perceive their primary role as advocates for critically ill newborns, and believe that their involvement in the resolution of treatment dilemmas should be increased. ^

Relatively high amounts of fats or oils (mayor que 40-50 g/kg diet) are frequently used in animal nutrition. Vegetables oils are richer in polyunsaturated fatty acids than animal fats. Most of the works studying the effect of different dietary fat sources are focused either on the existing differences on fat digestibility depending on their fatty acid composition (Wiseman et al., 1991) or on their effect on the carcass fat fatty acid profile (Sanz et al., 1999a). lnformation regarding the effect of dietary fat saturation on fat utilization and deposition it is more limited. lt is generally assumed that, apart from differences in digestion, fatty acids of different composition are equally used for metabolic purposes.

Through a case study of the diffusion of the celebrated West Gennan "dual system" of vocational training to the territory of the fonner German Democratic Republic, we develop the argument that local sociopolitical relations matter crucially for the successful transfer and implementation of institutional arrangements. Notwithstanding massive levels of government funding, the presence of complementary supports, and the concerted efforts of Ger­many's social partners, the dual system is experiencing significant difficulties in the new federal states of the East. These difficulties are not due simply to the particular politics of unification (the wholesale transfer of West German institutions whether or not they were appropriate to Eastern Germany) nor even simply to the paucity of dynamic private firms capable of and willing to train new apprentices. The difficulties stem also from the under­ lying weaknesses of the East German sociopolitical infrastructure on which the entire dual system rests. This. hy­ pothesis is elaborated and substantiated through a range of data on training in the East and especially through the use of detailed case studies of Leipzig and Chemrutz.

The expert contributors to this edited volume, representing a multidisciplinary selection of academics, examine the treatment of irregular migration, human trafficking and smuggling in EU law and policy. The various chapters explore the policy dilemmas encountered in efforts to criminalise irregular migration and humanitarian assistance to irregular immigrants. The book aims to provide academic input to informed policy-making in the next phase of the European Agenda on Migration. In his Foreword, Matthias Ruete, Director General of DG Home Affairs of the European Commission, writes: “This initiative aims to stimulate evidence-based policy-making and to bring fresh thinking to develop more effective policies. The European Commission welcomes the valuable contribution of this initiative to help close the wide gap in our knowledge about the smuggling of migrants, and especially the functioning of smuggling networks.”
