Estimation in an empirical bayes model for longitudinal and cross‐sectionally clustered binary data

Some studies generate data that can be grouped into clusters in more than one way. Consider for instance a smoking prevention study in which responses on smoking status are collected over several years in a cohort of students from a number of different schools. This yields longitudinal data, also cross‐sectionaliy clustered in schools. The authors present a model for analyzing binary data of this type, combining generalized estimating equations and estimation of random effects to address the longitudinal and cross‐sectional dependence, respectively. The estimation procedure for this model is discussed, as are the results of a simulation study used to investigate the properties of its estimates. An illustration using data from a smoking prevention trial is given.     

Jury theorems with multiple alternatives

I consider a game in which imperfectly informed jurors vote to select one of several possible choices when there is a natural ordering of the possibilities. Each juror votes for the largest alternative the juror would like to implement, and the alternative that is selected is the largest alternative supported by a given number of jurors. For non-unanimous voting rules, the probability of a mistaken judgment goes to zero as the number of jurors goes to infinity. I also give necessary and sufficient conditions to obtain asymptotic efficiency under unanimous voting rules, and show that unanimous rules may lead to a bias in which moderate outcomes are never chosen.     

Institutional Diversity and Performance in African Cotton Sectors

This article analyses the performance of cotton sectors across East, Southern, and West Africa, paying particular attention to the wide diversity of institutional arrangements that they now exhibit. It finds strong support for earlier contentions regarding trade‐offs between competition and coordination, and between the roles of public and private sectors. New insights provide concrete and context‐specific guidance to policy‐makers and stakeholders regarding the key challenges they will face and the risks they will need to manage as they work to improve productivity and ensure an equitable division of benefits within cotton sectors.     

It Takes a Village (Perhaps a Nation): Families,States, and Educational Achievement

Research in the United States has shown that children growing up in 2‐parent households do better in school than children from single‐parent households. We used the Trends in International Mathematics and Science Study (TIMSS) data to test whether this finding applied to other countries as well (N = 100,307). We found that it did, but that the educational gap was greater in the United States than in the other 13 countries considered. Results from 2‐level hierarchical linear models demonstrated that international differences in the educational gap were associated with several indicators of national policy and demographic contexts. No single policy appeared to have a large effect, but several policy combinations were associated with substantially reduced educational gaps between children from different family structures.     

An examination of the resurgence of ethnicity literature

This paper presents a critical review of the most frequently cited resurgence of ethnicity studies. Many of the sources cited in recently published ethnic relations books are found to lack an empirical base. They are essentially polemical, impressionistic and anecdotal works. Empirical studies that support the resurgence of ethnicity theme are also examined. Their shortcomings are noted. Nevertheless, these empirical studies provide convincing evidence that ethnic differences persist into the later generations. Overall, however, the empirical studies overwhelmingly document increasing assimilation. Virtually no evidence is found for the notion of a third generation resurgence.     

Black-White Differentials in Adult Homicide Mortality in the United States

Objective . This article examines individual level black-white differences in adult homicide mortality. Homicide is a major social problem and a central cause of preventable death in the United States. A homicide not only claims one life prematurely but can also devastate a family, friends, and a neighboring community. Methods . We link eight consecutive years of the National Health Interview Survey (1987–94) to the Multiple Cause of Death file through the National Death Index (1987–97), and use Cox proportional hazard models to examine the role of social factors in black-white homicide mortality in the United States. Results . We find that individual level sociodemographic characteristics—age, sex, marital status, education, employment status, and geographic factors—explain almost 35 percent of the racial differences in homicide mortality. Conclusions . These results demonstrate the contributions that National Center for Health Statistics data can make to criminological literature and reveal the mechanisms through which blacks experience higher homicide mortality than whites. Such illumination may lead to a reduction in the fourth leading preventable cause of death in the United States.     

Global civil society or ‘networked globality’: beyond the territorialist and societalist paradigm

The concept of global civil society (GCS) is central to treatments of globalization and to depictions of a contested globality. This article offers a novel critique of the concept and its value for a critical social science of globalization. It argues that received notions of GCS are rooted in territorialist and societalist paradigms of the social and should not be used to subvent an account of globalization located in the dynamics of trans and even post-societal and post-national connections and the kind of world they intimate. GCS and variants such as cosmopolitanism are examined to evaluate whether they can provide a way of bridging the gap between territorialist and societalist assumptions about the organization of the social and the increasingly post-societal and post-territorial nature of the world. The aim is to avoid the inviting, but ultimately misleading sleight of hand through which GCS is revealed as the boundary-less equivalent of civil society, but with all the normative and aesthetic baggage of the latter still attached. The article ends with a critical discussion of the claim that globalization processes of connection are producing a networked globality in which reflexive agency is not lost. To recognize this requires a radical take on networks and their ontologies and being skeptical about much of the received sociology of globalization.     

Reflections on dangerous fieldwork

Latin American fieldwork may involve danger for researcher and subject alike. The researcher must work to minimize his or her own or others’ exposure to violence. Unobtrusive methods such as Q-Methodology, participant observation, and quiet interviewing are recommended so that the researcher can build a sustaining and protecting network of contacts. This article discusses the interpersonal relations, problems of security, and field entry techniques involved in sensitive research situations. Ana Karina Galve de Peritore, his wife and frequent field collaborator, is a former professor of international relations at National Autonomous University of Mexico, and is currently a doctoral candidate in rural sociology at University of Missouri-Columbia.
