Biological weapons are considered, by the international community, as a weapon of mass destruction. When the Biological Weapons Convention (BWC) was negotiated during the 1960s and early 1970s, the negotiators considered unnecessary the establishment of an international organisation to supervise the implementation of the Convention’s provisions by the State parties. It is important to highlight that since the entry into force of the BWC, the international situation has significantly changed. For this reason perhaps the moment has arrived to consider again the proposal of settling down such an organisation in the framework of the strengthening the BWC.  相似文献

Ergonomics has been successful in increasing productivity and comfort in the work arena. It has also contributed to reducing occupational accidents. Despite this, ergonomics is frequently limited to understanding the health-disease process related to human-technology interactions, as this process is more complex than what can be understood from an ergonomic evaluation. Recognising this limit, this work ontologically and epistemologically contrasts the notions of 'human being' and 'social subject', and concludes that the study object of ergonomics, or human-technology interaction, greatly depends on social aspects that nowadays are not tackled explicitly: route (history), project, structure, agency, motivations and power. It also analyses how participatory ergonomics tacitly includes many of these aspects, including some implications that the change of notion, from 'human being' to 'social subject', brings to the understanding of the health-disease process and the reduction of associated risks during human activities.  相似文献

Organizations represent deliberately designed social contexts that are characterized by multi-level hierarchies. Interests and opportunity structures at each level usually do not overlap. We suggest that one of the reasons why intentional change efforts often fail to reach their objectives is because they are likely to trigger competing social mechanisms at different levels of the hierarchy. In order to illustrate this argument, we analyze the consequences of timely communication of planned organizational changes on perceived success of reorganizations. Two competing mechanisms are derived and tested with data from a telephone survey (carried out in 2003), among a sample of n = 412 Dutch business organizations that performed a reorganization. The commitment perspective predicts that early announcement of reorganization plans to middle management increases the likelihood of reorganization success, since it increases commitment and empowers middle management. The influence mechanism predicts that early information of non-managerial employees decreases the likelihood of reorganization success, because it enables employees to use the information to their own advantage, anticipate on the strategies of management, and organize opposition against the plans. We found that timely communication with middle management indeed increases chances for success, whereas timely communication with employees correlates with reorganization failure. However, not communicating with employees has an even stronger negative effect on reorganization success. No evidence could be found for our argument that the severity of the reorganization’s expected negative effects on the workforce moderates both mechanisms.  相似文献

Cash transfer programs have been the main social policy in the fight against poverty and inequality in Latin-American countries. This paper analyzes the impacts of the program Más Familias en Acción on the perception of poverty and subjective wellbeing in Colombia. The analyses are based on data from the Encuesta Nacional de Calidad de Vida between 2008 and 2016. Two empirical strategies were compared to account for the lack of randomness in groups of beneficiary and non-beneficiary families: (i) non-experimental designs (linear and nonlinear models with cross-sectional and pooled data); (ii) quasi-experimental designs (Propensity Score Matching and Inverse Probability Weighted Regression Adjustment). The results were robust to the different empirical strategies and emphasized that: (i) transfers increase the perception of food insecurity and subjective poverty; (ii) conditionalities involve positive impacts on different indicators of subjective wellbeing, especially health and education; (iii) general impacts on the perceptions of life are nonsignificant, as a result of divergent impacts on the dimensions of the subjective wellbeing of families.  相似文献

With the objective of theoretically and psychometrically updating the Regional Identity Scale (RIS) proposed by Zúñiga and Asún in 2004 and expanding the population for which it shows evidence of validity, a revision and revalidation of this instrument was performed via two studies. The first study included 1,113 university students from four regions of Chile, and the second included 1,200 adults from the same regions. Both samples were obtained via a random design through multistage conglomerates. The results enable us to propose a new version of the original scale (RIS-2) with suitable reliability indexes, solid evidence of both convergent validity and internal structure validity, and items with satisfactory psychometric quality. Furthermore, we verify the presence of a multifactor structure with three highly correlated dimensions. We conclude that the RIS-2 is a reliable, valid and conceptually broader instrument than the preceding version, so it is a useful tool to measure the intensity of regional identity in both university students and the adult population.  相似文献

Across the globe, the countryside faces the “generation problem”: Who will grow food when the current generation of aging small farmers and peasants disappears? A combination of objective and subjective factors effectively discourages young people from assuming the continuity of peasant and family farming, especially in countries that have experienced significant neoliberal dismantling of rural infrastructure and education. Rural social movements are increasingly building educational processes linked with small-scale, ecological farming in the hopes of reinforcing the development of identities and skills for peasant futures and cadre in the struggle for popular land reform, agroecology, and food sovereignty.  相似文献

Consumer Phase Risk Assessment for Listeria monocytogenes in Deli Meats   总被引:1,自引:0,他引:1  
The foodborne disease risk associated with the pathogen Listeria monocytogenes has been the subject of recent efforts in quantitative microbial risk assessment. Building upon one of these efforts undertaken jointly by the U.S. Food and Drug Administration and the U.S. Department of Agriculture (USDA), the purpose of this work was to expand on the consumer phase of the risk assessment to focus on handling practices in the home. One-dimensional Monte Carlo simulation was used to model variability in growth and cross-contamination of L. monocytogenes during food storage and preparation of deli meats. Simulations approximated that 0.3% of the servings were contaminated with >10(4) CFU/g of L. monocytogenes at the time of consumption. The estimated mean risk associated with the consumption of deli meats for the intermediate-age population was approximately 7 deaths per 10(11) servings. Food handling in homes increased the estimated mean mortality by 10(6)-fold. Of all the home food-handling practices modeled, inadequate storage, particularly refrigeration temperatures, provided the greatest contribution to increased risk. The impact of cross-contamination in the home was considerably less. Adherence to USDA Food Safety and Inspection Service recommendations for consumer handling of ready-to-eat foods substantially reduces the risk of listeriosis.  相似文献

Nursing is considered a woman friendly profession; however, career advancement in nursing, as in other fields, is predicated on masculine models of promotion, making mobility difficult for working mothers. To learn more about how women negotiate caregiving responsibilities at home and at work, focus groups were conducted with 26 ethnically and socioeconomically diverse registered nurses, licensed vocational nurses, and aides. Three themes emerged from these discussions: tension between the value nurses assigned to paid caregiving and societal devaluation of this work; "costs" of paid caring and emotional labor on family life; and the presence of both obstacles to and opportunities for career advancement. Caregiving experiences were shaped by professional status. Implications for women's well being and career advancement are discussed.  相似文献

Resumen

Hemos realizado un estudio diferencial sobre las interpretaciones causales y sus consecuencias cognitivo- afectivas en un contexto de robo, utilizando como marco teórico el último modelo atribucional de Weiner (1986). Para ello, hemos aplicado cuestionarios de autoinforme a 1.450 sujetos menores de edad. Los resultados, obtenidos mediante análisis de la varianza y técnicas de regresión, indican (1) que existe una taxonomía de las causas claramente diferenciada en función de las dimensiones—locus, estabilidad y controlabilidad—, y de la perspectiva—actor/observador—de los sujetos; (2) que la estabilidad de las causas determina la predicción de reincidencia, y que ésta es mayor en los sujetos que dicen haber cometido más robos, y (3) que el sentimiento de culpa está determinado por la controlabilidad de las causas y varía como función inversa de la experiencia delictiva. Finalmente, señalamos algunas implicaciones teóricas y aplicadas de este trabajo.  相似文献
