Purpose – The goal of this chapter is to demonstrate the importance of incorporating gene by environment (G×E) interactions into behavioral science theory and research.

Design/methodology/approach – We critique behavioral genetics, discuss the emergence of epigenetics, review findings on G×E effects, and present the differential susceptibility model of gene–environment interplay.

Findings – The studies reviewed demonstrate that genetic variation often interacts with environmental context to influence the probability of various behaviors. Importantly, in many, and perhaps most, of the studies reviewed, the genetic variable, unlike the environmental variable, has little if any main effect on the outcome of interest. Rather, the influence of the genetic variable is limited to its moderation of the effect of the environmental construct.

Research limitations/implications – Molecular G×E research does not undermine the importance of environmental factors; rather it shows how social scientific explanations of human behavior might be made more precise by incorporating genetic information. This suggests expanded research opportunities for those interested in social causation.

Social implications – This model of molecular G×E research presented suggests that a substantial proportion of the population is genetically predisposed to be more susceptible than others to environmental influence. We argue that this model of G×E is particularly relevant to sociologists and psychologists and has the potential to enhance the development of theory in both areas.

Originality/value – This chapter will be of particular interest to sociologists and psychologists who have found the behavioral genetic paradigm off-putting because of its emphasis on genetic main effects and genetic determinism. The current chapter offers an alternative model that may better capture the available data and better integrate social processes with genetic and biological processes.

Juvenile delinquency research has identified two vital (and related) concepts to this area of study: age of onset and escalation. In this investigation, escalation is examined as a function of early drinking. Added to this are the influences of deviant peers and the social control effects of family and church. My analysis shows that consuming alcohol at a young age is correlated with illegal drug use, committing a greater number of illegal acts, committing more serious offences, and being confronted by police for delinquent behavior. Moreover, I show that peer influence has a greater impact on individual behavior than do other social control mechanisms. In conclusion, I offer a critique of current policies aimed at teenage drinking and argue in favor of preventative, rather than prohibitive strategies.

This volume begins with two chapters that draw on evolutionary sociology to advance our understanding of interpersonal processes and their role in social organization. In “The Biology and Neurology of Group Processes,” Jonathan H. Turner and Alexandra Maryanski draw on three areas of evolutionary sociology (cladistic analysis, comparative neuroanatomy, and ecological analysis) to show how understanding the selection pressures acting on the brain over millions of years can help us get a better grasp on the biologically based capacities and propensities that are involved in group processes such as role-taking and role-making. An improved understanding of these processes means better explanations of how humans create, sustain, and change social structures and culture – topics that lie at the core of sociological inquiry. At the same time, Turner and Maryanski's chapter will give sociologists much to think about and debate, as one of the main conclusions of their argument is that neurology explains human capacities to develop non-kin groups more than culture. The next chapter entitled “Sacrifice, Gratitude, and Obligation: Serial Reciprocity in Early Christianity,” by Richard Machalek and Michael W. Martin, may be seen as giving more equal explanatory weight to culture and biology in a theoretical analysis that combines a focus on cognitive processes (historically unique meanings and ideas) with evolutionary sociological insights about emotions in order to generate better explanations of complex socio-historical developments. Specifically, Machalek and Martin extend Rodney Stark's analysis of how ideas contributed to the rise of Christianity by showing how the evolved features of human emotionality related to “paying it forward” (or serial reciprocity in more formal terms) may have also played an important role in this historical process. Both chapters provide excellent examples of the value of combining multiple theoretical perspectives and paying attention to the interplay of social and biological forces.

Purpose – This study demonstrates that serious episodes of presidential ill health can have positive impacts on role performance.

Design/methodology – The author utilizes both primary source materials (personal interviews with White House physicians and several other physicians who treated Reagan at the hospital, and the writings of key Reagan aides and family members) and secondary source materials (writings of political scientists, historians, and journalists).

Findings – Reagan was at first in critical condition. It was then that his Secretary of State appeared to make a bold grab for power, an act that contributed materially to the end of his political career. Additionally, the administration’s failure to invoke the presidential disability amendment allowed the official chain of command to be in doubt. Finally, the significant increase in Reagan’s popularity that flowed from his light-hearted demeanor after he was shot is examined here in terms of the President’s subsequent legislative successes.

Originality/value – This study suggests strongly that Reagan’s impressive legislative achievements in mid-1981 were due significantly to his heroic response to having been shot.

This is a comprehensive list of books, some pamphlets, and a few sound recordings about or by Ronald (and Nancy) Reagan. Collections of photographs and cartoons as well as biographies, political commentary, speeches, quotations and even recipes are represented. Omitted are books in which there is only brief mention of him. The bibliography was compiled in connection with a major exhibit on Ronald Reagan at the Colorado State University Library. It is the author's intention to continue to collect Reagan materials.

Scholars increasingly recognize the centrality of legal ideas and language to the political vision that inspires American conservatism. However, relevant studies have been limited to the discursive practices that motivate conservative activism at the grass-root level. Exploration of the legal discourses employed by prominent public officials thus carries significant scholarly potential. For example, this chapter's investigation of President Ronald Reagan reveals that his political vision was suffused with legal discourse. Reagan's legal discourse, moreover, has exerted constitutive effects both on American conservatism and on the form and substance of a great deal of contemporary American public policy.

The institution of an annual series devoted to current and ongoing research in economics and business should be considered one of the notable developments during the period under review. Long standing need for such a reference not withstanding, there has been until this year no systematic attempt to organize a continuing series which concentrated on selected areas of ongoing research, especially adapted to the Jahrbucher format. By facilitating the publication of research papers which are longer than the conventional journal‐length article yet shorter than a monograph, publishing outlets available to scholars in the field have been infinitely expanded. Two years ago, the Royal Economic Society and the Social Science Research Council of Great Britain, developed an experimental series, published by Macmillan, entitled Surveys of Applied Economics. The JAI Press, Greenwich, Conn., has now come out with an annual series, which is expected to fill the gaps in at least seventeen areas of economic theory and business.

Heritability studies attempt to estimate the contribution of genes (vs. environments) to variation in phenotypes (or outcomes of interest) in a given population at a given time. This chapter scrutinizes heritability studies of adverse health phenotypes, emphasizing flaws that have become more glaring in light of recent advances in the life sciences and manifest most visibly in epigenetics.

Drawing on a diverse body of research and critical scholarship, this chapter examines the veracity of methodological and conceptual assumptions of heritability studies.

The chapter argues that heritability studies are futile for two reasons: (1) heritability studies suffer from serious methodological flaws with the overall effect of making estimates inaccurate and likely biased toward inflated heritability, and, more importantly (2) the conceptual (biological) model on which heritability studies depend – that of identifiably separate effects of genes versus the environment on phenotype variance – is unsound. As discussed, contemporary bioscientific work indicates that genes and environments are enmeshed in a complex (bidirectional, interactional), dynamic relationship that defies any attempt to demarcate separate contributions to phenotype variance. Thus, heritability studies attempt the biologically impossible. The emerging research on the importance of microbiota is also discussed, including how the commensal relationship between microbial and human cells further stymies heritability studies.

Understandably, few sociologists have the time or interest to be informed about the methodological and theoretical underpinnings of heritability studies or to keep pace with the incredible advances in genetics and epigenetics over the last several years. The present chapter aims to provide interested scholars with information about heritability and heritability estimates of adverse health outcomes in light of recent advances in the biosciences.
