A bstract . A massive volume of literature has been generated over recent years concerning the nature of work organizations and resultant effects upon worker satisfaction and enterprise efficiency. Between extreme radical and conservative views, a good deal of attention has focused on worker ownership and the locus of power in the organization. Worker ownership can lead to beneficial results, but only if carefully structured. Worker participation in decision making is the key, but the transfer from authoritarianism is difficult. Any substantial transfer of enterprise ownership is remote. Even transformation to greater power sharing, short of ownership change, will be slow and fragile.  相似文献

Societal change, which takes a variety of directions and forms and in no way can be assimilated or reduced to a single dimension, is often accompanied by a perception of insufficient understanding and lack of control. There is a frustrated need for mastering complexity and instability, separating the voluntary from the involuntary, the intended from the unintended, opportunities from risks, getting to the real causes and dominating the uncertain implications of social change. Social change catches us unprepared and confused. In this context statistics are generally considered a fundamental instrument of knowledge, but also part of the problem! In the public debate and in the specialized literature, the ability to measure social phenomena through current statistics and indicators is increasingly questioned. Data-it is claimed-are lacking, particularly longitudinal data; their quality (accuracy, relevance, timeliness, comparability, etc.) should be improved; indicators do not provide early warning signals, policy performance evaluation, and a precise indication of outcomes. Statistics cannot be used as a reliable and timely basis for decision making by individuals, organizations, governments, and for understanding these decisions. In some cases, statistics have been accused of giving a misleading and false picture of reality: do we measure the real extent of social exclusion and unemployment? Do we fully capture the quality of life and the degradation of the environment? Mismeasurement has been deemed by some commentators as being responsible for the wrong focus in inflation and stabilization policies, science and technology, unemployment and poverty. The productivity paradox, the informal economy, failure to measure welfare and the quality of urban life are instances where statistics do not seem to provide complete and satisfactory answers to the demand for information and knowledge. Our paper illustrates how, quite independently of measurement techniques and data production processes, the inadequacy of the conceptual framework may explain mismeasurement in relation to complex (multidimensional) and dynamic social phenomena. It is then to social theories, explanations and interpretations that statisticians need to turn, in order to come to grips with the new challenges in social measurement. We will develop this thesis looking at a few cases where measurement issues can be connected to both theoretical and empirical difficulties. The statistical gap which reveals itself in the mismeasurement or difficult measurement of social phenomena is closely interconnected with the social science gap. Only close collaboration between statisticians and social scientists can bring about continuous advancement in social science and quality improvement in social statistics.  相似文献

The current article examines social media applications as a tool for positive social change. The number of users on applications from Facebook to Twitter and Instagram continues to increase in all demographics. These tools are being integrated into our daily activities and challenging boundaries, roles, and even possibilities globally. Currently, there exists a gap in developing competent leaders capable of leading change using social media. Education leaders and leadership education programs can adapt the values of the Social Change Model to reflect and apply digital competencies to their practice. Digital leadership requires reflection on online self‐awareness and congruence, grappling with the controversy that comes with cyber civility and how to be a digital citizen prepared to inspire positive social change.  相似文献

为了研究纵轴式掘进机用截齿的损坏形式及机理,现场收集了典型的损坏截齿,从截线距、截齿工作角度的设计、截割头现场管理维护等方面对其造成的损坏形式及机理进行了分析。分析表明,截齿的非正常损坏一般不是由单一因素造成,主要由截齿布置参数、使用管理、地质条件等因素综合作用的结果。最后针对布置截齿时处理截齿座干涉问题及解决方法提出了建议。这些对如何提高截齿及截割头的使用寿命具有指导意义。  相似文献

This article discusses aspects of stability and instability in the social hierarchy of French urban housing over time. The analysis is based on the creation of housing categories using the occupancy characteristics of 58 types of housing units. Each category represents the position of a housing unit and its occupant in a socially hierarchized residential space. Our study looked at the movements of housing units between these different positions, the residential distribution of 11 cohorts of households and the residential trajectories of social groups from 1978 to 1996. Its results highlight the emergence of a twofold residential contrast — between the top and the bottom of the social hierarchy, and between the generations who benefited from economic growth during the period known as the Trente Glorieuses and other generations. These contrasts are expressed through a significant erosion of the most socially mixed sections of the housing stock, most recently through increasingly rigid channels of access to housing, and through upward residential trajectories that now exclude working‐class social groups and are no longer totally guaranteed to young households in the higher social groups. Cet article porte sur les stabilités et les instabilités temporelles de la hiérarchie sociale de l’habitat urbain français. L’analyse est basée sur la construction de catégories d’habitat élaborées à partir des caractéristiques d’occupation de 58 types de logements. Chaque catégorie traduit une position du logement et de son occupant dans un espace résidentiel socialement hiérarchisé. L’étude présente, entre 1978 et 1996, les mouvements des logements entre ces différentes positions, la distribution résidentielle de 11 cohortes de ménages et les trajectoires résidentielles des groupes sociaux. Les résultats font apparaître la mise en place d’une double opposition résidentielle entre le haut et le bas de la hiérarchie sociale et entre les générations qui ont bénéficié de l’expansion économique des Trente Glorieuses et les autres. Ces oppositions se traduisent par une érosion sensible des fractions de parc les plus mixées socialement, des filières d’accès au logement de plus en plus rigides dans la période la plus récente, et des trajectoires résidentielles ascendantes qui excluent dorénavant les catégories populaires et ne sont plus totalement assurées pour les jeunes ménages des couches supérieures.  相似文献

Sensitivity Analysis of Continuous Incomplete Longitudinal Outcomes   总被引:1,自引:0,他引:1  
Even though models for incomplete longitudinal data are in common use, they are surrounded with problems, largely due to the untestable nature of the assumptions one has to make regarding the missingness mechanism. Two extreme views on how to deal with this problem are (1) to avoid incomplete data altogether and (2) to construct ever more complicated joint models for the measurement and missingness processes. In this paper, it is argued that a more versatile approach is to embed the treatment of incomplete data within a sensitivity analysis. Several such sensitivity analysis routes are presented and applied to a case study, the milk protein trial analyzed before by Diggle and Kenward (1994) . Apart from the use of local influence methods, some emphasis is put on pattern-mixture modeling. In the latter case, it is shown how multiple-imputation ideas can be used to define a practically feasible modeling strategy.  相似文献
