This review discusses North American and European research from the sociology of valuation and evaluation (SVE), a research topic that has attracted considerable attention in recent years. The goal is to bring various bodies of work into conversation with one another in order to stimulate more cumulative theory building. This is accomplished by focusing on (a) subprocesses such as categorization and legitimation, (b) the conditions that sustain heterarchies, and (c) valuation and evaluative practices. The article reviews these literatures and provides directions for a future research agenda.

A burgeoning literature spanning sociologies of culture and social network methods has for the past several decades sought to explicate the relationships between culture and connectivity. A number of promising recent moves toward integration are worthy of review, comparison, critique, and synthesis. Network thinking provides powerful techniques for specifying cultural concepts ranging from narrative networks to classification systems, tastes, and cultural repertoires. At the same time, we see theoretical advances by sociologists of culture as providing a corrective to network analysis as it is often portrayed, as a mere collection of methods. Cultural thinking complements and sets a new agenda for moving beyond predominant forms of structural analysis that ignore action, agency, and intersubjective meaning. The notion of \"cultural holes\" that we use to organize our review points both to the cultural contingency of network structure and to the increasingly permeable boundary between studies of culture and research on social networks.

Laboratory experiments are a widely used methodology for advancing causal knowledge in the physical and life sciences. With the exception of psychology, the adoption of laboratory experiments has been much slower in the social sciences, although during the past two decades the use of lab experiments has accelerated. Nonetheless, there remains considerable resistance among social scientists who argue that lab experiments lack \"realism\" and generalizability. In this article, we discuss the advantages and limitations of laboratory social science experiments by comparing them to research based on nonexperímental data and to field experiments. We argue that many recent objections against lab experiments are misguided and that even more lab experiments should be conducted.

Standards and standardization aim to render the world equivalent across cultures, time, and geography. Standards are ubiquitous but underappreciated tools for regulating and organizing social life in modernity, and they lurk in the background of many sociological works. Reviewing the relevance of standards and standardization in diverse theoretical traditions and sociological subfields, we point to the emergence and institutionalization of standards, the difficulties of making standards work, resistance to standardization, and the multiple outcomes of standards. Rather than associating standardization with totalizing narratives of globalization or dehumanization, we call for careful empirical analysis of the specific and unintended consequences of different sorts of standards operating in distinct social domains.

Sociological theory and research point to the importance of social relationships in affecting health behavior. This work tends to focus on specific stages of the life course, with a division between research on childhood/adolescent and adult populations. Yet recent advances demonstrate that early life course experiences shape health outcomes well into adulthood. We synthesize disparate bodies of research on social ties and health behavior throughout the life course, with attention to explaining how various social ties influence health behaviors at different life stages and how these processes accumulate and reverberate throughout the life course.

During the past decade, social mechanisms and mechanism-based explanations have received considerable attention in the social sciences as well as in the philosophy of science. This article critically reviews the most important philosophical and social science contributions to the mechanism approach. The first part discusses the idea of mechanism based explanation from the point of view of philosophy of science and relates it to causation and to the covering-law account of explanation. The second part focuses on how the idea of mechanisms has been used in the social sciences. The final part discusses recent developments in analytical sociology, covering the nature of sociological explananda, the role of theory of action in mechanism-based explanations, Merton's idea of middle-range theory, and the role of agent-based simulations in the development of mechanism-based explanations.

Context: Participatory research (PR) is the co-construction of research through partnerships between researchers and people affected by and/or responsible for action on the issues under study. Evaluating the benefits of PR is challenging for a number of reasons: the research topics, methods, and study designs are heterogeneous; the extent of collaborative involvement may vary over the duration of a project and from one project to the next; and partnership activities may generate a complex array of both short- and long-term outcomes. Methods: Our review team consisted of a collaboration among researchers and decision makers in public health, research funding, ethics review, and community-engaged scholarship. We identified, selected, and appraised a large-variety sample of primary studies describing PR partnerships, and in each stage, two team members independently reviewed and coded the literature. We used key realist review concepts (middle-range theory, demi-regularity, and context-mechanism-outcome configurations [CMO]) to analyze and synthesize the data, using the PR partnership as the main unit of analysis. Findings: From 7,167 abstracts and 591 full-text papers, we distilled for synthesis a final sample of twenty-three PR partnerships described in 276 publications. The link between process and outcome in these partnerships was best explained using the middle-range theory of partnership synergy, which demonstrates how PR can (1) ensure culturally and logistically appropriate research, (2) enhance recruitment capacity, (3) generate professional capacity and competence in stakeholder groups, (4) result in productive conflicts followed by useful negotiation, (5) increase the quality of outputs and outcomes over time, (6) increase the sustainability of project goals beyond funded time frames and during gaps in external funding, and (7) create system changes and new unanticipated projects and activities. Negative examples illustrated why these outcomes were not a guaranteed product of PR partnerships but were contingent on key aspects of context. Conclusions: We used a realist approach to embrace the heterogeneity and complexity of the PR literature. This theory-driven synthesis identified mechanisms by which PR may add value to the research process. Using the middle-range theory of partnership synergy, our review confirmed findings from previous PR reviews, documented and explained some negative outcomes, and generated new insights into the benefits of PR regarding conflicts and negotiation between stakeholders, program sustainability and advancement, unanticipated project activity, and the generation of systemic change.

Students of social inequality have noted the presence of mechanisms militating toward cumulative advantage and increasing inequality. Social scientists have established that individuals' choices are influenced by those of their network peers in many social domains. We suggest that the ubiquity of network effects and tendencies toward cumulative advantage are related. Inequality is exacerbated when effects of individual differences are multiplied by social networks: when persons must decide whether to adopt beneficial practices; when network externalities, social learning, or normative pressures influence adoption decisions; and when networks are homophilous with respect to individual characteristics that predict such decisions. We review evidence from literatures on network effects on technology, labor markets, education, demography, and health; identify several mechanisms through which networks may generate higher levels of inequality than one would expect based on differences in initial endowments alone; consider cases in which network effects may ameliorate inequality; and describe research priorities.

Epigenetics is a burgeoning area of biomedicai research into the mechanisms by which genes are regulated—how the activity of producing proteins is controlled. Although molecular epigenetic research is highly biochemical, it is of interest to sociologists because some epigenetic changes are environmentally mediated and can persist across the life span or into further generations. Environmental epigenetic research tracks mechanisms by which social forces—from pollution to nutrition to mothering to traumatic experience—become molecularly embodied, affect gene expression, and induce durable changes in behavior and health. We begin with an introduction to the science of environmental epigenetics focused on articulating the logic of experimentation and explanation in this field. Turning to sociologists' key interests, we review the growing literature on epigenetics of socioeconomic status. Finally, we consider how epigenetics offers opportunities and challenges for sociological research on both empirical and theoretical grounds.

Research during the past decade shows that social class or socioeconomic status (SES) is related to satisfaction and stability in romantic unions, the quality of parent-child relationships, and a range of developmental outcomes for adults and children. This review focuses on evidence regarding potential mechanisms proposed to account for these associations. Research findings reported during the past decade demonstrate support for an interactionist model of the relationship between SES and family life, which incorporates assumptions from both the social causation and social selection perspectives. This review concludes with recommendations for future research on SES, family processes, and individual development in terms of important theoretical and methodological issues yet to be addressed.
