Copyright @ 2012 Elsevier B.V.The advent of increasingly stringent and wider ranging European Union legislation relating to water and the environment has required regulators to assess compliance risk and to respond by formulating appropriate pollution control measures. To support this process the UK Water Industry has completed a national Chemicals Investigation Programme (CIP), to monitor over 160 wastewater treatment works (WwTWs) for 70 determinands. Final effluent concentrations of zinc, polynuclear aromatic hydrocarbons (fluoranthene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(g,h,i)perylene and indeno(1,2,3-cd)pyrene), “penta” congeners (BDEs) 47 and 99, tributyltin, triclosan, erythromycin, oxytetracycline, ibuprofen, propranolol, fluoxetine, diclofenac, 17β-estradiol and 17α-ethinyl estradiol exceeded existing or proposed Environmental Quality Standards (EQSs) in over 50% of WwTWs. Dilution by receiving water might ensure compliance with EQSs for these chemicals, apart from the BDEs. However, in some cases there will be insufficient dilution to ensure compliance and additional management options may be required

Social job resources as sources of meaningfulness and its effects on nurses’ vigor and emotional exhaustion: a cross-sectional study among spanish nurses

This study investigates the mediating role of psychological meaningfulness among social job resources (i.e., coworkers and supervisor support), vigor, and emotional ex haustion in a nursing context. In spite of progress in under standing which organizational influence affects nurses’ vigor and emotional exhaustion, the psychological mechanisms as sumed to underlie the associations have not been fully ex plored. The sample for this study consisted of 171 nurses from Spanish hospitals (54.4 %) and Primary Care Centers (45.6 %). The mediation model was tested using the bootstrapping procedure. Our findings confirmed that psycho logical meaningfulness fully mediates the impact of social job resources on vigor at work. Moreover, psychological mean ingfulness partially mediated the impact of social job resources on emotional exhaustion. Results suggest that mean ingfulness plays an important role in the connection between job resources, vigor, and emotional exhaustion. The findings contribute to our understanding of the psychological processes that can explain how job resources contribute to the energetic aspect of burnout and engagement among nurses. Providing nurses with more social job resources, such as coworker and supervisor support, could activate their levels of personal meaningfulness and thus enhance their levels of well-being at workThis research was funded by an FPU grant from the Spanish Ministry of Education (AP2010-0099) and by a project from the Spanish Ministry of Economy and Competitiveness (FEM2012-34692

Decision Support Tool for energy-efficient, sustainable and integrated urban stormwater management

[EN] The use of Sustainable Drainage Systems (SUDS) to manage urban runoff and contribute to environmental and landscape improvement is now widely known, but its application is still limited in many regions, like in Mediterranean countries. In addition, there is a lack of Decision Support Tools that consider all their benefits in the decision making process in a clear and integrated holistic way. In this paper, the (ESTORMED)-S-2 Decision Support Tool is presented. This tool analyses the impact of stormwater management in the urban environment and introduces energetic and environmental criteria in the decision making process. Therefore, it aims to fill in the existing "gap" between SuDS manuals and guidelines and regional and local decision makers, since it quantifies SuDS benefits and includes them in the comparison of different stormwater scenarios. Finally, the results of applying this tool to compare drainage infrastructures in a real urban development are described. (C) 2016 Elsevier Ltd.

Coalition governance and foreign policy decision making

This article explores processes of coalition governance in foreign policy. Specifically, it argues that such processes are shaped by two interrelated dimensions of coalition set-up: first, the allocation of the foreign ministry to the senior or a junior coalition partner and, second, the degree of policy discretion which is delegated to that ministry. Bringing these two dimensions together, the article distinguishes four types of coalition arrangement for the making of foreign policy, which are expected to have predictable implications for the process of foreign policy-making and, ultimately, for the foreign policy outputs of multi-party coalitions and their quality
