Domestic welfare reform and the management of international migration in Britain have been described by David Cameron as ‘two sides of the same coin’. Heightened conditions and sanctions for the benefit-dependent domestic population, both in and out of work, are being harnessed as a means of promoting labour market change and reducing demand for low-skilled migrants – often EU workers, whose own access to benefit is being curtailed. Arguments about the post-national expansion of rights and associated cosmopolitan debate implicitly measure migrants rights against a normative model of citizenship as the yardstick of full social inclusion, but with little attention to how far citizenship itself falls short of this promise. Taking Britain as a case study, this paper considers how the concept of civic stratification can further advance analysis of the link between domestic welfare, migration and human rights in a context of intensifying controls for both migrants and citizens.  相似文献

This article considers the relationship between the Equality Act 2010 and the Charities Act 2011 (in Scotland, the Charities and Trustee Investment (Scotland) Act 2005) in the context of adoption by same-sex couples and the complex exceptions to the Equality Act that charities may be able to rely upon in order to continue to discriminate. It concludes that the law is confusing to the point of opacity, to the detriment of those seeking to exercise their rights and those called on to adjudicate conflicts.  相似文献

Potent synthetic opioids including fentanyl and its analogs are frequently encountered in the field and require detection and identification by first responders to maintain the safety of drug abusers, first responders, health-care providers, and the public at large. Due to the low concentration at which these substances may be encountered and the complicating matrices within which they may be dispersed, the use of portable gas chromatography–mass spectrometry (GC–MS) for their identification in the field offers great potential value. This research established that portable GC–MS is a useful method for the detection and identification of a large number of synthetic opioids, especially fentanyl and its analogs. In this study, 250 synthetic opioids and related substances including 210 fentanyl analogs were analyzed using portable GC–MS. It was concluded that 225 of the 250 (90.0%) opioids analyzed were successfully detected onboard at the time of analysis and identified as either the substance (55.2%) or an analog (34.8%). These outcomes have equivalent benefit for the field analysis of illicit drugs due to both initiating the same subsequent actions by first responders.  相似文献

This article addresses whether there are differences in regulatory regimes in the devolved nations of the UK. It focuses on the divergence between rhetoric and practice around improving performance of local authorities. By discussing general understanding of public sector quality and the possible role for regulators in ensuring quality it shows that Scotland and Wales have developed different approaches since devolution of power in 1999. By comparing case studies from each of the nations it shows that practices vary much less than could be expected based on the previous research. This is likely to be due to shared underlying assumptions about performance and how to improve it, rather than the regulatory regimes themselves. It is argued that external pressure and support are vital, and that these functions can be damaged by reducing involvement of the state in safeguarding quality of public service delivery.  相似文献

Malawi is one of the poorest countries in Africa. There is widespread, though not universal, agreement about the shape of poverty in the country and the policy challenge this sets. Agriculture continues to be the most obvious means to stimulate broad-based rural growth and to provide levels of food security and income needed for the majority rural population. A longitudinal study over a decade during which radical policy and political changes occurred provides the data and basis for discussing the appropriate policy directions for reducing poverty.  相似文献

This article focusses on the specific impact of the cuts in legal aid funding on the charitable sector. The sector plays a significant role in advice giving. Some charities have the provision of legal advice as their sole purpose, whilst the work of other charities includes the giving of legal advice. Funding comes via a number of sources including legal aid, local authorities and charitable trusts. Whilst this volume highlights the legal aid reforms that will lead to significant cuts in funding, this article notes that charitable providers of legal advice have also suffered major cuts from their other traditional funding sources. Against this background, the article considers the serious and often unforeseen consequences for charities of the legal aid reforms, which go far beyond the impact on the high street law firm and access to justice for claimants.  相似文献

Since the development of the striagraph, various attempts have been made to enhance forensic investigation through the use of measuring and imaging equipment. This study describes the development of a prototype system employing an easy‐to‐use software interface designed to provide forensic examiners with the ability to measure topography of a toolmarked surface and then conduct various comparisons using a statistical algorithm. Acquisition of the data is carried out using a portable 3D optical profilometer, and comparison of the resulting data files is made using software named “MANTIS” (Mark and Tool Inspection Suite). The system has been tested on laboratory‐produced markings that include fully striated marks (e.g., screwdriver markings), quasistriated markings produced by shear‐cut pliers, impression marks left by chisels, rifling marks on bullets, and cut marks produced by knives. Using the system, an examiner has the potential to (i) visually compare two toolmarked surfaces in a manner similar to a comparison microscope and (ii) use the quantitative information embedded within the acquired data to obtain an objective statistical comparison of the data files. This study shows that, based on the results from laboratory samples, the system has great potential for aiding examiners in conducting comparisons of toolmarks.  相似文献
