Auditing the health and safety performance of organisations is now recognised as an essential ingredient of successful health and safety management systems. The audit protocol — the question sets—is, however, only one of a number of factors which determine the end value of auditing. The competence of auditors, their insights into the organisations subject to scrutiny, their independence and the feedback and decision making processes that help organisations to review and change the way they operate are equally important. Much of the process of auditing needs to be systematic, methodical and scientific. However the art of the informed analysis and inspired interpretation can also add value to the total management process. Auditing alone will not prevent accidents and injuries. Health and safety management systems do that. Auditing seeks to assess the efficiency effectiveness of the systems. Informed management action must then follow, to maintain and improve them. This paper outlines five essential components of health and safety management; policy making, organising, planning, performance measurement and review which provide the environment in which effective auditing systems operate. It is derived from the work of HSE's Accident Prevention Advisory Unit and the advice published in “Successful Health and Safety Management” in 1991.  相似文献

Transgenic Indian mustard [Brassica juncea (L.) Czern.] plants overproducing the enzymes gamma-glutamylcysteine synthetase (ECS) or glutathione synthetase (GS) were shown previously to have increased levels of the metal-binding thiol peptides phytochelatins and glutathione, and enhanced Cd tolerance and accumulation. Furthermore, transgenic Indian mustard plants overexpressing adenosine triphosphate sulfurylase (APS) were shown to have higher levels of glutathione and total thiols. These results were obtained with a solution culture. To better examine the phytoremediation potential of these transgenics, a greenhouse experiment was performed in which the transgenics were grown on metal-contaminated soil collected from a USEPA Superfund site near Leadville, Colorado. A grass mixture used for revegetation of the site was included for comparison. The ECS and GS transgenics accumulated significantly (P < 0.05) more metal in their shoot than wild-type (WT) Indian mustard, while the APS plants did not. Of the six metals tested, the ECS and GS transgenics accumulated 1.5-fold more Cd, and 1.5- to 2-fold more Zn, compared with wild-type Indian mustard. Furthermore, the ECS transgenics accumulated 2.4- to 3-fold more Cr, Cu, and Pb, relative to WT. The grass mixture accumulated significantly less metal than Indian mustard: approximately 2-fold less Cd, Cu, Mn, and Zn, and 5.7-fold less Pb than WT Indian mustard. All transgenics removed significantly more metal from the soil compared with WT Indian mustard or an unplanted control. While WT did not remove more metal than the unplanted control for any of the metals tested, all three types of transgenics significantly reduced the soil metal concentration, and removed between 6% (Zn) and 25% (Cd) of the soil metal. This study is the first to demonstrate enhanced phytoextraction potential of transgenic plants using polluted environmental soil. The results confirm the importance of metal-binding peptides for plant metal accumulation and show that results from hydroponic systems have value as an indicator for phytoremediation potential.  相似文献

The current meta-analysis sought to evaluate the empirical evidence for the victim precipitation model, which has become an increasingly popular yet controversial theory in the organizational sciences. We did so by testing the prediction that some victim dispositional traits contribute to or provoke experiences of mistreatment. We additionally provided preliminary examinations of two distinct conceptual explanations underlying the empirical relationships between victim personality and mistreatment. Finally, we examined the support for the situational antecedents of experienced mistreatment to compare the relative evidence for each of these dominant theoretical explanations. Results for the tests of the victim precipitation model showed that only victim negative affectivity was consistently related to experienced mistreatment. Examinations of the explanations for the relationships between victim personality and victimization showed relatively weak support for the notion that certain employees are more likely to perceive mistreatment and for the proposition that certain employees are mistreated because they are also more likely to engage in mistreatment. Finally, the situational predictors of mistreatment were all supported, and a test of relative importance revealed that the situational antecedents accounted for more variance in mistreatment than the victim dispositional traits. Implications for the theoretical understanding of the origins of mistreatment are discussed.  相似文献

Climate variability is amongst an array of threats facing agricultural livelihoods, with its effects unevenly distributed. With resource conflict being increasingly recognised as one significant outcome of climate variability and change, understanding the underlying drivers that shape differential vulnerabilities in areas that are double-exposed to climate and conflict has great significance. Climate change vulnerability frameworks are rarely applied in water conflict research. This article presents a composite climate–water conflict vulnerability index based on a double exposure framework developed from advances in vulnerability and livelihood assessments. We apply the index to assess how the determinants of vulnerability can be useful in understanding climate variability and water conflict interactions and to establish how knowledge of the climate–conflict linked context can shape interventions to reduce vulnerability. We surveyed 240 resource users (farmers, fishermen and pastoralists) in seven villages on the south-eastern shores of Lake Chad in the Republic of Chad to collect data on a range of exposure, sensitivity and adaptive capacity variables. Results suggest that pastoralists are more vulnerable in terms of climate-structured aggressive behaviour within a lake-based livelihoods context where all resource user groups show similar levels of exposure to climate variability. Our approach can be used to understand the human and environmental security components of vulnerability to climate change and to explore ways in which conflict-structured climate adaptation and climate-sensitive conflict management strategies can be integrated to reduce the vulnerability of populations in high-risk, conflict-prone environments.  相似文献

A laboratory-scale column experiment was conducted to evaluate the effect of organic carbon amendments on the mobility of As, Cu, Fe, Mn, Mo, Ni, Pb, Sb, Tl and Zn in mine tailings. Three columns were packed with sulfide- and carbonate-rich tailings, which were amended with a 1:1 (vol.) mixture of peat and spent brewing grain at proportions of 0, 2 and 5vol.%. A simulated input solution characterized by circumneutral pH and elevated concentrations of SO(4) and S(2)O(3) was passed through the columns for 540 days. The input solution contained low concentrations of metal(loid)s during the initial 300 days and elevated concentrations thereafter. Decreases in mass transport of S(2)O(3) were observed in all columns; with increased attenuation observed at 5 vol. % organic carbon content. Removal of Mn, Ni, Cu, Sb and Mo was observed in all columns during the initial 300 days. However, during this time, mobilization of Fe, As, Zn and Pb was observed, with the greatest increases in concentration observed at the higher organic carbon content. During the final 240 days, S(2)O(3) removal was enhanced in columns containing organic carbon, and Fe, Mn, Ni, Tl, As and Sb removal also was observed. This study demonstrates the influence of organic carbon amendments on metal(loid) mobility in mine tailings. Decreases in mass discharge of metal(loid)s may be achieved using this technique; however, site-specific geochemical conditions must be considered before field-scale implementation.  相似文献

It is 10 years since the adoption of the Cape Town Principles and Best Practices on the Prevention of Recruitment of Children into the Armed Forces and on Demobilization and Social Reintegration of Child Soldiers in Africa. The field of programming for the reintegration of children associated with armed forces and armed groups has made significant strides in this period. However, important gaps in the knowledge base remain. This paper examines empirical evidence that supports lessons learned from work with children formerly connected with fighting forces. It evaluates what is known, where promising practice exists, and lacunae in five programming areas: psychosocial support and care; community acceptance; education, training and livelihoods; inclusive programming for all war-affected children; and follow-up and monitoring. While the 2007 Paris Commitments to Protect Children from Unlawful Recruitment or Use by Armed Forces or Groups mark an emerging consensus on many issues, there is still a critical need for more systematic studies to develop the evidence base supporting intervention in this area.  相似文献

Although sustainable bioenergy development in Africa is critically debated, if projects are developed within a credible framework, opportunities for sustainability arguably can arise. This paper presents research on the characteristics of sustainable biofuel projects as provided in the literature and according to expert opinions obtained by way of a survey involving thirty-eight international experts. Participants were selected for their expertise in the fields of environmental, social and economic sustainability relating to biofuels in Africa. The survey results suggest that projects which display a high degree of transparency, incorporate local stakeholder involvement, and ideally include local villagers as partners are more likely to achieve sustainable biofuel production. Experts also indicated that reconciling diverse stakeholder objectives alongside the principles of sustainable development remains an ongoing challenge. A process is recommended for sustainable biofuel development, which attempts to harmonise efficiency, stakeholder interaction and the integration of diverse stakeholder perspectives. To support the process, it is recommended that an advisory/mediating body that acts according to best practice principles would be of great assistance. Such an advisory/mediating body would be conversant with local land, social, economic and environmental conditions, project sustainability and administration, and also advise on biofuel framework educational needs.  相似文献
