Temporality and Social Change: The Case of 19th Century China and Japan

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.     

A Statistical Framework for Hypothesis Testing in Real Data Comparison Studies

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.     

Managing Money in Marriage: Multilevel and Cross‐National Effects of the Breadwinner Role

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.     

Not just hot air: normative codes of conduct induce cooperative behavior

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.

Transnationalism over the Life Course

The sociological research on transnational migration has blossomed over the past decade to become one of the most discussed ideas in the sociology of immigration and the discipline more generally. In this review, we draw attention to transnationalism research that includes elements of the life course perspective. We distinguish two ways that the life course approach can be integrated with research on transnationalism: Research that examines the unique transnational aspects of a single life stage, and research that considers transnational trajectories and transitions as individuals move through two or more life stages. We propose that more explicit attention to the life course in transnational research will lead to interesting and enlightening new research directions.     

Exchange Relationships in Inshore Fisheries1

Research on the long‐term, informal exchange strategies of harvesters and dealers working in inshore fisheries has been important to theory surrounding economic exchange. In transaction costs economics, this research provides evidence for economic exchange governed by trust, and in exchange theory, it provides evidence for the emergence of cooperation and trust. In this article I examine the emergence of economic exchange relationships in the new sea urchin fishery. The research is ethnographic in nature, utilizing a variety of data sources including participant observation, in‐depth interviews, and existing quantitative data. I find that, just as experience or improved efficiency can have an impact on the emergence of trust between exchange partners, potential exchange partners can be deemed untrustworthy based on general characteristics unrelated to the particular individual. Once established, these assessments become part of the strategic context of exchange in the fishery.     

Individualized Marriage and the Integration of Resources

In individualized marriages, spouses maintain independence in their relationship. In individualized marriages, do married couples manage their money in pooled accounts or do they keep separate accounts? We answer this question with the 2002 International Social Survey Programme (N = 18,587;31 country contexts) and examine how variation in the individualization of marriage is related to variation in resource integration within marriage. We make two contributions. First, we found that individualization matters. When couples understood and practiced individualized marriage, they were more likely to keep their money separate. The presence of individualized approaches to marriage and individualized alternatives to marriage within a country were also related to a higher likelihood of couples keeping money separate. Second, we found that integrating resources remained a constitutive part of marriage. Despite trends toward individualization and growing alternatives to marriage, most married couples continued to pool their money.     

Interethnic Romantic Relationships: Enacting Affiliative Ethnic Identities

Through in‐depth interviews with respondents who were in interethnic relationships (N = 28), the authors extended and refined a new approach to mate selection based on affiliative ethnic identities (T. Jimenez, 2010). Rather than assimilation and a breakdown of ethnic group boundaries, they found that people pursued interethnic relationships because of the ethnic differences they include. These relationships gave them access to an affiliate ethnic or multicultural identity. This perspective does not challenge but rather complements existing theories of mate selection, including the role of opportunity structures, exchange of benefits, and growing acceptance of or freedom to pursue interethnic relationships. Ethnic differences can remain central as people meet, fall in love, and marry across these differences.
