Manifold factors have been identified as causal mechanisms in social change, but an important one–temporality–has been neglected. Temporality is the social time that characterizes any society, and that social time is consequential for the rate and direction of change. The three dimensions of temporality are temporal pattern, temporal orientation, and temporal perspective. The differences between the Japanese and Chinese along these three dimensions help explain their differential responses to the 19th century Western challenge. Specifically, two propositions are examined in the light of the historical data: a society's temporality limits the range of adaptive responses to new circumstances, and the symbols of social time act as a mechanism of social control. 相似文献

The shirking incentives arising within team production are in general counteracted by monitoring and sanctioning. However,
these mechanisms are usually associated with high monitoring costs and cannot be applied to all parts of the production process.
In a laboratory experiment we analyze the impact of less costly elements of organizational structure, such as normative codes
of conduct and screening tests, on team production efficiency. We find that more allusions to a firm context lead to higher
contributions. In particular, codes of conduct significantly increase cooperation and at the same time reduce free-riding
behavior. Our study provides empirical evidence that normative codes of conduct are an effective means of increasing team
production efficiency.

Identity Agents: Parents as Active and Reflective Participants in Their Children's Identity Formation 总被引:1,自引:0,他引:1
The paper introduces the concept of identity agents. This concept refers to those individuals who actively interact with children and youth with the intention of participating in their identity formation, and who reflectively mediate larger social influences on identity formation. This contrasts with the focus of mainstream research in the identity field that tends to portray adolescents as the sole reflective agents involved in mature identity development. The paper presents a theoretical analysis presenting the importance of the concept for the formulation of a comprehensive contextual theory of identity formation. The particulars of this concept are illustrated through the presentation of a qualitative report of religious parents actively encouraging their children's processes of identification, co‐participating in their children's identity's formation, and reflectively deliberating their parental roles and goals in regards to this process. 相似文献

In computational sciences, including computational statistics, machine learning, and bioinformatics, it is often claimed in articles presenting new supervised learning methods that the new method performs better than existing methods on real data, for instance in terms of error rate. However, these claims are often not based on proper statistical tests and, even if such tests are performed, the tested hypothesis is not clearly defined and poor attention is devoted to the Type I and Type II errors. In the present article, we aim to fill this gap by providing a proper statistical framework for hypothesis tests that compare the performances of supervised learning methods based on several real datasets with unknown underlying distributions. After giving a statistical interpretation of ad hoc tests commonly performed by computational researchers, we devote special attention to power issues and outline a simple method of determining the number of datasets to be included in a comparison study to reach an adequate power. These methods are illustrated through three comparison studies from the literature and an exemplary benchmarking study using gene expression microarray data. All our results can be reproduced using R codes and datasets available from the companion website http://www.ibe.med.uni-muenchen.de/organisation/mitarbeiter/020_professuren/boulesteix/compstud2013. 相似文献

ResumenSe propone un acercamiento socio-construccionista para el estudio de las subjetividades de género sexual frente al tratamiento cognitivista y sociocognitivista, dominantes en Psicología Social, en la investigación sobre identidad sexual, estereotipos y categorías de género. Asimismo se parte de ciertos planteamientos provenientes de la epistemología feminista postmoderna que ponen un énfasis especial en el análisis del lenguaje como instrumento mediatizador, regulador y modelador de la subjetividad y el género desde una perspectiva de las relaciones de poder y su regulación de subjetividades. Desde este triple marco el objetivo es analizar si la subjetividad de género femenino, supuestamente heredada y compartida según la mayoría de estudios de estereotipos, modela las identificaciones de las propias mujeres o si éstas desarrollan formas de resistencia hacia ella. Por todo ello la metodología de Análisis del Discurso aparece como la estrategia de investigación más adecuada. Los resultados del Análisis del Discurso de las narraciones de las mujeres sobre ellas mismas pone de manifiesto distintas subjetividades con diferentes niveles de agencia en relación a la reproducción o transformación de la escisión de género femenino. 相似文献

We examine whether institutionalized practices and beliefs regarding breadwinning roles are associated with the choice of more or less equal money management strategies in marriage. Using cross‐national data from 21 country contexts in the International Social Survey Programme and multilevel modeling, we find that in contexts of shared breadwinning, there is a greater likelihood of shared management of money, controlling for the relative income contribution of each spouse. We also find some evidence that the effect of spouses’ relative income contributions diminishes in contexts of shared breadwinning. Our analysis comparing women’s and men’s money management is consistent with previous research indicating that women’s management may be more work than power. 相似文献

This paper presents a socioeconomic occupational grouping of the foreign-born gainful workers of the United States at each census from 1870 through 1930. This series is then used to estimate the net immigration of gainful workers into the United States during each of the six decades from 1870 to 1930 cross classified by occupational group and sex. The following three conclusions are then drawn from the above two series. First, the socioeconomic position of the foreign-born population of the United States remained relatively stable from 1870 to 1910 but then increased appreciably from 1910 to 1930. Second, although most of the contribution that immigration made to the United States labor force was in the form of semiskilled and unskilled workers, the relative importance of professional, clerical, and skilled workers increased almost continuously from 1870 to 1930. Third, the “new immigration” was not less skilled than the “old immigration”. On the contrary it was actually more skilled than the “old immigration”. 相似文献

Many survivors of child sexual abuse who engage in psychotherapy also experience physical health problems. This article summarizes the findings of a multiphased qualitative study about survivors' experiences in healthcare settings. The study informed the development of the Handbook on Sensitive Practice for Health Care Practitioners: Lessons from Adult Survivors of Childhood Sexual Abuse (Schachter, Stalker, Teram, Lasiuk, & Danilkewich, 2009), which is intended to help healthcare providers from all disciplines understand the effect of child sexual abuse on some survivors' abilities to access and benefit from health care. This paper discusses what psychotherapists can learn from the healthcare experiences of the male survivors who participated in this project. It also offers practical suggestions for supporting male clients who experience difficulty seeking treatment for physical health concerns. 相似文献
