Codes of ethics and ethics guidelines define standards of professional conduct, and ways to prioritize or balance ethical principles when these appear to be in conflict. In 1991 an international and interdisciplinary group of scholars met at the University of Toronto to discuss these problems in a Workshop on Ethical Considerations in Scholarship and Science. A document, “The Toronto Resolution”; (TTR), was developed, providing twelve principles for incorporation into scientific and scholarly codes, with the object of ensuring that professionals in science recognize the potential consequences of their work in the broader social context. To examine the extent to which existing codes are consonant with The Toronto Resolution's 12 principles, a content analysis was conducted on the codes of 21 Ontario‐based scientific and scholarly organizations. Criteria used in the content analysis were standardized and determined to be reliable. Only a weak correspondence was found between the contents of the codes of the scientific and scholarly organizations surveyed here and the principles set out in TTR. In particular, guidelines on specific social issues such as environmental effects or conflict resolution are scarcely mentioned at all. This study encourages consideration of The Toronto Resolution by the ethics committees of scientific and scholarly associations, as codes are revised or as new interpretations of principles in the codes evolve.  相似文献

Policymakers in the UK and beyond have sought to promote interventions to encourage social capital‐building among disadvantaged groups. One specific concern is that those with limited access to social capital/social network relationships will be at greater risk of experiencing both unemployment and poverty. By analyzing longitudinal data from the British Household Panel Survey (BHPS), we seek to identify significant relationships between poverty and the likelihood of entering employment, and different measures of ‘sociability’ and social isolation. Crucially, we discuss if and how measures of sociability/social isolation are associated with jobseekers' varying chances of exiting and re‐entering work and how this varies with their experience of poverty. These issues are important because if sociability impacts on the likelihood of entering employment from a state of worklessness, then policymakers need to understand how cycles of social and labour market exclusion are associated with the rates of entering employment in order to develop effective interventions to improve jobseekers' employability and combat poverty. Following an analysis of BHPS data, we identify lessons for policy for combating long‐term unemployment and promoting social inclusion.  相似文献

This paper examines the role of informal job search methods on the labour market outcomes of displaced workers. Informal job search methods could alleviate short-term labour market difficulties of displaced workers by providing information on job opportunities, allowing them to signal their productivity and may mitigate wage losses through better post-displacement job matching. However if displacement results from reductions in demand for specific sectors/skills, the use of informal job search methods may increase the risk of job instability. While informal job search methods are associated with lower wage losses, they lead to increased job instability and increased risk of subsequent job displacement.  相似文献

The theorization of postmodernism as the cultural logic of late capitalism has generated a number of debates among Latinos in the US and among Latin American critics in particular. This article examines a number of writings published between 1989 and 1994 by Latin American critics focusing on the viability of seeing Latin America as postmodern. We argue that in the rush to accept First World theoretical frameworks, there has been much confusion and a collapsing of economic, political and cultural categories. Conflating market growth and shifts with social change and the availability of a plurality of consumer goods with the distribution of goods and services, some critics have been quick to label cultural production in Latin America as ‘postmodern’. What is needed is a delimitation of the categories used, an examination of the cultural debate in relation to other debates on development, social movements, democratization and alliance politics, as well as an examination of local intellectual debates within the global context of restructuring and transnational capital.  相似文献

This paper is concerned with interval estimation of an autoregressive parameter when the parameter space allows for magnitudes outside the unit interval. In this case, intervals based on the least-squares estimator tend to require a high level of numerical computation and can be unreliable for small sample sizes. Intervals based on the asymptotic distribution of instrumental variable estimators provide an alternative. If the instrument is taken to be the sign function, the interval is centered at the Cauchy estimator and a large sample interval can be created by estimating the standard error of this estimator. The interval proposed in this paper avoids estimating this standard error and results in a small sample improvement in coverage probability. In fact, small sample coverage is exact when the innovations come from a normal distribution.  相似文献

Molecular dynamic computer simulation is an essential tool in materials science to study atomic properties of materials in extreme environments and guide development of new materials. We propose a statistical analysis to emulate simulation output with the ultimate goal of efficiently approximating the computationally intensive simulation. We compare several spatial regression approaches including conditional autoregression (CAR), discrete wavelets transform (DWT), and principle components analysis (PCA). The methods are applied to simulation of copper atoms with twin wall and dislocation loop defects, under varying tilt tension angles. We find that CAR and DWT yield accurate results but fail to capture extreme defects, yet PCA better captures defect structure.  相似文献

We describe several analyses in which robustness considerations have proved relevant. These examples exhibit the importance of (a) graphic displays as aids to formulating a preliminary model; (b) summary statistics that reduce the influence of outliers, that (c) give added opportunities of detecting relationships, and (d) are not unduly sensitive to granularity in the observations; and (e) techniques that pay due attention to anomalies in the data that superficially may appear to be negligible but that can obscure important effects. Finally, we make some general comments on the advantages and disadvantages of robust methodology.  相似文献
