Upgrading low‐waged and insecure work is central to contemporary labour and development initiatives, from the UN Sustainable Development Goals to the United Kingdom ‘Taylor Review’. The International Labour Organization's notion of unacceptable forms of work (UFW) is a crucial contribution. Yet the regulatory frameworks that can effectively address UFW are unclear. This article builds on a novel framework ‐ the Multidimensional Model of UFW. Drawing on theoretical literatures at the frontline of regulation scholarship, it proposes a strategic approach to UFW regulation that supports development, acknowledges the constrained resources of low‐income countries, and targets expansive and sustainable effects. Two key concepts are identified: points of leverage and institutional dynamism. Globally‐prominent regulatory frameworks are assessed as a starting point for mapping the strategic approach: the Mathadi Act of Maharashtra, India; Uruguayan domestic work legislation; minimum wages in the global North and South; and United Kingdom regulation of ‘zero‐hours contracts’. 相似文献

The tensile strength of a surgical suture is essential in maintaining the integrity of vascular anastomoses. While faulty operative technique and the loading strength of individual sutures have been implicated in spontaneous suture line disruptions, there has, to date, never been a published postmortem analysis of a suture that has known to have failed. We present the case of suture line disruption leading to fatal exsanguination in a 77-year-old man following carotid endarterectomy with a facial vein patch. Using both dissecting and scanning electron microscopy, we determined that surgical technique (an untied knot) was the cause of the suture line disruption. The removal of a broken or untied suture at surgery or at autopsy should not preclude proper analysis of the failed suture, because the results can have both medico-legal and public health implications. 相似文献

The luminol chemiluminescence presumptive test for blood is based on the mild peroxidase activity of hemoglobin in basic peroxide solution. However, this test is subject to interference by strong oxidants, certain transition metal ions, and true peroxidases. This paper reports methods for reducing the interference caused by hypochlorite-containing bleaches. Amines such as 1,2-diaminoethane react rapidly with hypochlorite without interfering significantly with the hemoglobin-catalyzed oxidation. Thus, addition of 0.1 mol/L 1,2-diaminoethane to a standard luminol-peroxide spray lead to almost complete inhibition of hypochlorite-induced chemiluminescence while satisfactory chemiluminescence was still observed from bloodstains. If time allows, an alternative method for reducing interference from hypochlorite bleach is to wait several days until the bloodstains have dried thoroughly, by which time the hypochlorite will have decomposed. 相似文献

A rapid method for screening drug seizure samples for 3,6-diacetylmorphine (heroin), which consists of a simple hydrolysis procedure and flow-injection analysis with two chemiluminescence reagents, is described. Before hydrolysis, 3,6-diacetylmorphine evokes an intense response with a tris(2,2'-bipyridyl)ruthenium(III) reagent (prepared by dissolving the perchlorate salt in acetonitrile), and a relatively weak chemiluminescence response with a second reagent: potassium permanganate in an aqueous acidic polyphosphate solution. However, the permanganate reagent is extremely sensitive toward the hydrolysis products of 3,6-diacetylmorphine (i.e., 6-monoacetylmorphine and morphine). Some compounds commonly found in drug laboratories may cause false positives with tris(2,2'-bipyridyl)ruthenium(III), but do not produce the markedly increased response with the permanganate reagent after the hydrolysis procedure. The combination of these two tests therefore provides an effective presumptive test for the presence of 3,6-diacetylmorphine, which we have verified with 14 samples obtained from a forensic science laboratory. 相似文献

Because of the domination of development and administrative planning by economists there has in the past been a concentration on variables that are mostly economic and measurable and a tendency to give insufficient attention to socio-cultural and socio-political variables. Now perspectives are changing and there is an awareness of the need to use more accurate and complete data on social and cultural phenomena. There is as a result a need to appreciate the contribution that geographers and cartographers can make. This article reviews the small scale socio-cultural mapping of third world countries. It considers the available range of such maps and carto-bibliographical guides, and proceeds to consider how socio-cultural mapping could be extended in a way that would be useful for development planners and administrators. 相似文献
