Similarity breeds connection. This principle—the homophily principle—structures network ties of every type, including marriage, friendship, work, advice, support, information transfer, exchange, comembership, and other types of relationship. The result is that people's personal networks are homogeneous with regard to many sociodemographic, behavioral, and intrapersonal characteristics. Homophily limits people's social worlds in a way that has powerful implications for the information they receive, the attitudes they form, and the interactions they experience. Homophily in race and ethnicity creates the strongest divides in our personal environments, with age, religion, education, occupation, and gender following in roughly that order. Geographic propinquity, families, organizations, and isomorphic positions in social systems all create contexts in which homophilous relations form. Ties between nonsimilar individuals also dissolve at a higher rate, which sets the stage for the formation of niches (localize...

Birds of a Feather: Homophily in Social Networks

It is argued that P-values and the tests based upon them give unsatisfactory results, especially in large samples. It is shown that, in regression, when there are many candidate independent variables, standard variable selection procedures can give very misleading results. Also, by selecting a single model, they ignore model uncertainty and so underestimate the uncertainty about quantities of interest. The Bayesian approach to hypothesis testing, model selection, and accounting for model uncertainty is presented. Implementing this is straightforward through the use of the simple and accurate BIC approximation, and it can be done using the output from standard software. Specific results are presented for most of the types of model commonly used in sociology. It is shown that this approach overcomes the difficulties with P-values and standard model selection procedures based on them. It also allows easy comparison of nonnested models, and permits the quantification of the evidence for a null hypothesis of interest, such as a convergence theory or a hypothesis about societal norms.

A Treatise on the Family. G. S. Becker. Cambridge, MA: Harvard University Press. 1981. Gary Becker is one of the most famous and influential economists of the second half of the 20th century, a fervent contributor to and expounder of the University of Chicago free-market philosophy, and winner of the 1992 Nobel Prize in economics. Although any book with the word "treatise" in its title is clearly intended to have an impact, one coming from someone as brilliant and controversial as Becker certainly had such a lofty goal. It has received many article-length reviews in several disciplines (Ben-Porath, 1982; Bergmann, 1995; Foster, 1993; Hannan, 1982), which is one measure of its scholarly importance, and yet its impact is, I think, less than it may have initially appeared, especially for scholars with substantive interests in the family. This book is, its title notwithstanding, more about economics and the economic approach to behavior than about the family. In the first sentence of the preface, Becker writes "In this book, I develop an economic or rational choice approach to the family." Lest anyone accuse him of focusing on traditional (i.e., material) economics topics, such as family income, poverty, and labor supply, he immediately emphasizes that those topics are not his focus. "My intent is more ambitious: to analyze marriage, births, divorce, division of labor in households, prestige, and other non-material behavior with the tools and framework developed for material behavior." Indeed, the book includes chapters on many of these issues. One chapter examines the principles of the efficient division of labor in households, three analyze marriage and divorce, three analyze various child-related issues (fertility and intergenerational mobility), and others focus on broader family issues, such as intrafamily resource allocation. His analysis is not, he believes, constrained by time or place. His intention is "to present a comprehensive analysis that is applicable, at least in part, to families in the past as well as the present, in primitive as well as modern societies, and in Eastern as well as Western cultures." His tone is profoundly conservative and utterly skeptical of any constructive role for government programs. There is a clear sense of how much better things were in the old days of a genderbased division of labor and low market-work rates for married women. Indeed, Becker is ready and able to show in Chapter 2 that such a state of affairs was efficient and induced not by market or societal discrimination (although he allows that it might exist) but by small underlying household productivity differences that arise primarily from what he refers to as "complementarities" between caring for young children while carrying another to term. Most family scholars would probably find that an unconvincingly simple explanation for a profound and complex phenomenon. What, then, is the salient contribution of Treatise on the Family? It is not literally the idea that economics could be applied to the nonmarket sector and to family life because Becker had already established that with considerable success and influence. At its core, microeconomics is simple, characterized by a belief in the importance of prices and markets, the role of self-interested or rational behavior, and, somewhat less centrally, the stability of preferences. It was Becker's singular and invaluable contribution to appreciate that the behaviors potentially amenable to the economic approach were not limited to phenomenon with explicit monetary prices and formal markets. Indeed, during the late 1950s and throughout the 1960s, he did undeniably important and pioneering work extending the domain of economics to such topics as labor market discrimination, fertility, crime, human capital, household production, and the allocation of time. Nor is Becker's contribution the detailed analyses themselves. Many of them are, frankly, odd, idiosyncratic, and off-putting. …

We investigate whether income inequality affects subsequent growth in a cross-country sample for 1965-90, using the models of Barro (1997), Bleaney and Nishiyama (2002) and Sachs and Warner (1997), with negative results. We then investigate the evolution of income inequality over the same period and its correlation with growth. The dominating feature is inequality convergence across countries. This convergence has been significantly faster amongst developed countries. Growth does not appear to influence the evolution of inequality over time. Outline

What is already known about this topic? Attitudes of disapproval toward public health measures led to behaviors that could increase vulnerability to contracting coronavirus disease 2019 (COVID-19). What is added by this report? Chinese citizens rated the necessity of mitigation measures for combating COVID-19 higher than did Americans (4.81 vs. 4.03 on a 1–5 scale). The China–US difference was attributable to 1) Chinese citizens having more confidence in scientists than Americans and 2) Chinese citizens almost invariably accepting the necessity of COVID-19 mitigation measures, regardless of their confidence in scientists. What are the implications for public health practice? Building public support for population health measures and public trust in science is crucial for handling epidemic crises.

Scholars are divided over whether narrative/storytelling occupies a central position in health-related behaviour or in the health-related issues discussed on social media platforms. This study explored Chinese COVID-19 vaccination expressions on Douyin, China’s biggest short-video sharing social media platform, and found that narration is still the most important tool employed by Chinese users when talking about COVID-19 vaccinations on Douyin, emphasizing nationalism and widespread optimism. Most of the narratives employed by Chinese users come from a first-person perspective. Nationalism, as manifested in the support expressed for national policies, rather than the external platform characteristics of memetics, makes the Chinese users’ expressions about COVID-19 vaccinations similar on Douyin. Douyin seems to have become a ‘pilgrimage platform’ for the Chinese public to express their patriotic sentiment and their trust in the country and the government.

Personal Narrative under Nationalism: Chinese COVID-19 Vaccination Expressions on Douyin

A substantial literature suggests that family disruption leads to lower educational attainment among children. We focus on how the effects of parental divorce on children’s education differ across families with varying likelihoods of disruption. Using U.S. panel data, with careful attention to the assumptions and methods needed to estimate total and mediating causal effects, we find a significant effect of parental divorce on educational attainment among children whose parents were unlikely to divorce, for whom divorce was thus a relative shock. We find no effect among children whose parents were likely to divorce and for whom divorce was one of many disadvantages, and thus less economically and socially disruptive. We also find that the observed effect of divorce on children’s education is strongly mediated by post-divorce family income. Children’s psychosocial skills also explain a portion of the effect among children with a low propensity for parental divorce, while cognitive skills play no role in explaining the negative association between divorce and children’s education. Our results suggest that family disruption does not uniformly disrupt children’s attainment.

Unequal Families, Unequal Effects: How Parental Divorce Differentially Impacts Children's Educational Attainment

The paper examines earnings inequality and earnings returns to education in China among four types of workers characterized by their labor market history. Compared to workers staying in the state sector, early market entrants no longer enjoyed advantages. The commonly observed higher earnings returns to education in the market sector are only limited to recent market entrants. This results from the aggregation of two very different types of workers: those who were \"pushed\" and those who \"jumped\" into the market in later stage of the reform. The findings challenge the prevailing wisdom that education is necessarily more highly rewarded by the market sector.
