This paper presents the Ergonomic Work Analysis method in a Brazilian Dentist's office. Through the study, the constraints and the strategies in avoiding them were identified. It was found that dentists hardly use the position most indicated by the International Organization for Standardization (ISO) and the Federation Dentaire Internacionale (FDI) for both the patient and the dentist, which is respectively supine and 9 o'clock, due to the limited space and layout. Five types of treatments performed by the professional have been studied. The frequency and duration of actions in these treatments were accounted for and the standard positions adopted were identified. The AET was found to be a very suitable method to grasp the dentist's activity and build a point of view of the profession, which is characterized as: stressful, perfectionist and restrictive. Time management is presented as an important strategy to control the tension arising from performing the treatments. 相似文献

In the economic and social aftermath of the 2008 crisis there has been an important and growing new wave of highly qualified Portuguese emigration comprising scientists. No or very few public policies have been designed to reverse this phenomenon, risking the consequences of brain drain. International literature argues that professional reasons are central to scientists’ decision to migrate, even after the 2008 crisis. Spending some time in a foreign country to study, research, or teach, is perceived as a common step in an individual academic trajectory and an advantage for a successful professional career in academia. It is also encouraged by European Union policies. Twelve individual portraits of Portuguese scientists living in central Europe reveal how important other factors are to the migration decision‐making process. These factors include the economic crisis, student mobility programmes, and the current Portuguese scientific system revision. 相似文献

Armed combat in childhood is a form of child abuse. It may lead to serious consequences, including post‐traumatic stress disorder. The inherent emotional abuse and acts or omissions by caregivers may cause behavioural, cognitive, emotional or mental disorder in the child. Nineteen former child soldiers were interviewed in a rehabilitation centre using a standard questionnaire. Reasons for recruitment included: volunteered (18), hatred of enemy (revenge) (5), virtue of being a freedom fighter (martyrdom) (9), as a means of supporting their family (economic) (3). One child was abducted, 7 joined for fear of the ‘enemy’ abducting them, and in 5 a family member was killed by ‘enemy’ or own group. The children were involved in manual labour (15), guard duty (15), front‐line fighting (7), bomb manufacture (5), setting sea/land mines (5) and radio and communication (2). Fifteen were trained in firearms and 14 in self‐destruction. Twelve children attempted to or did run away and 11 refused to obey orders or argued. This led to various punishments, including kitchen duty, beatings, imprisonment, blackmail or death threats. A majority of the children felt sad and emotionally upset when they remembered their mother and family. Children's involvement in war, whatever the ‘justifications’ may be, should always be considered as forced, as they cannot truly comprehend their action in war. The responsibility must be taken by the adult caregivers. The following definition of the abuse of children in armed conflict is proposed: ‘The involvement of dependent, developmentally immature children and adolescents in armed conflict they do not truly comprehend, to which they are unable to give informed consent, and which adversely affects the child's right to unhindered growth and identity as a child’. Firm international agreement on guidelines for the lower age limit of recruitment of children into armed forces is required. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

This paper provides an analysis of the Minimal Overlap Rule, a solution for bankruptcy problems introduced by O’Neill (1982). We point out that this rule can be understood as a composition
of Ibn Ezra’s proposal and the recommendation given by the Constrained Equal Loss Rule. Following an interpretation of bankruptcy problems in terms of TU games, we show that the Minimal Overlap Value is the unique solution for bankruptcy games which satisfies Anonymity and Core Transition Responsiveness. 相似文献

The residential and social segregation of whites from blacks creates a socialization process we refer to as “white habitus.” This white habitus limits whites' chances for developing meaningful relationships with blacks and other minorities spatially and psychologically. Using data from the 1997 Survey of College Students' Social Attitudes and the 1998 Detroit Area Study, we show that the spatial segregation experienced by whites from blacks fosters segregated lifestyles and leads them to develop positive views about themselves and negative views about blacks. First, we document the high levels of whites' residential and social segregation. Next, we examine how whites interpret their own self‐segregation. Finally, we examine how whites' segregation shapes their racial expressions, attitudes, cognitions, and even their sense of aesthetics as illustrated by their views on the subject of interracial marriage. 相似文献

In this paper we introduce a new three-parameter exponential-type distribution. The new distribution is quite flexible and can be used effectively in modeling survival data and reliability problems. It can have constant, decreasing, increasing, upside-down bathtub and bathtub-shaped hazard rate functions. It also generalizes some well-known distributions. We discuss maximum likelihood estimation of the model parameters for complete sample and for censored sample. Additionally, we formulate a new cure rate survival model by assuming that the number of competing causes of the event of interest has the Poisson distribution and the time to this event follows the proposed distribution. Maximum likelihood estimation of the model parameters of the new cure rate survival model is discussed for complete sample and censored sample. Two applications to real data are provided to illustrate the flexibility of the new model in practice. 相似文献

In the past decade, growing public concern about novel technologies with uncertain potential long‐term impacts on the environment and human health has moved risk policies toward a more precautionary approach. Focusing on mobile telephony, the effects of precautionary information on risk perception were analyzed. A pooled multinational experimental study based on a 5 × 2 × 2 factorial design was conducted in nine countries. The first factor refers to whether or not information on different types of precautionary measures was present, the second factor to the framing of the precautionary information, and the third factor to the order in which cell phones and base stations were rated by the study participants. The data analysis on the country level indicates different effects. The main hypothesis that informing about precautionary measures results in increased risk perceptions found only partial support in the data. The effects are weaker, both in terms of the effect size and the frequency of significant effects, across the various precautionary information formats used in the experiment. Nevertheless, our findings do not support the assumption that informing people about implemented precautionary measures will decrease public concerns. 相似文献

Gender, home and family in cultural capital theory 总被引:1,自引:0,他引:1
Silva EB 《The British journal of sociology》2005,56(1):83-103
The paper argues that Bourdieu's stress on early familiarization for the highest value of cultural capital is closely linked to his idea, strongly emphasized in Distinction, about the role of family and domestic life for individual development and social positions. The role of women, as mothers and homemakers, is crucial in this process. Yet, Bourdieu defines social origin as deriving from the father. The centrality to Bourdieu's thinking of a resilient traditional pattern of masculine domination and feminine submission constitutive of the Western gender habitus explains both his stress on ‘normalcy’ for the production of legitimate dispositions, and his resistance to incorporating into his thinking the implications of recent transformations in home family living, which have destabilized the gender order. It is thus important to consider contemporary feminist analyses of the family and home life and their significance for a renewed theory of cultural capital. The paper considers two sets of literature. Firstly, it addresses the manners in which home and family are conceptualized in Bourdieu's key texts where these issues were prominent in the development of his thinking on cultural capital. The second set of literature includes texts by feminist academics in the fields of family, gender and the body, which analyse the destabilizing of the gender order and everyday family living in contemporary society. Two questions are addressed on the basis of these reflections: (1) Is cultural capital an individual or a household resource? (2) How does cultural capital relate to personal interdependencies at the level of family and households? 相似文献
