Stress and the military go hand-in-hand, particularly in combat environments. While some personality traits or types weaken relationships between stress and performance, others, such as psychopathy, may strengthen them. In the present chapter, we consider the ramifications of individuals with high levels of psychopathy or psychopathic tendencies in the military with regard to both their own stress and performance and that of those around them. We discuss different reactions to psychological and physical stress, as well as the implications of psychopathic tendencies as they relate to current military issues, including gender, leadership, teamwork, turnover, post-traumatic stress disorder, and suicide. By juxtaposing relevant research findings on stress and psychopathy, we conclude that psychopathic tendencies should have neither uniformly negative nor positive effects on stress and performance in the military. Rather, effects on such individuals and the peripheral others with whom they interact will likely vary greatly depending on numerous factors.

While the field of criminology is rooted in sociological tradition, biosocial criminology has emerged as a promising perspective in studying antisocial behaviors. This perspective encompasses the research from other scientific disciplines, namely behavioral genetics and molecular genetics. At its core, biosocial criminology views criminal behavior as a function of both the social environment as well as biological/genetic factors. This chapter will provide a description of the prominent methodologies used in behavioral genetics and molecular genetics, a review of the empirical research, an overview of some of the statistical and methodological issues, as well as a discussion on the potential avenues for future research.

The NCS was based on multistage area probability sample of people age 15–54 in the non-institutionalized civilian population of the coterminous U.S., with a supplemental sample of students living in campus group housing (Kessler et al., 1994). The survey was carried out face-to-face in the homes of respondents by professional interviewers employed by the Survey Research Center (SRC) at the University of Michigan. The survey was carried out between September 1990 and February 1992. The response rate was 82.6%, with a total of 8,098 respondents participating in the survey. A supplemental non-response survey was carried out to adjust for non-response bias, with a random sample of initial non-respondents offered a financial incentive to complete a short form of the diagnostic interview. A non-response adjustment weight was constructed for the main survey data to compensate for elevated rates of disorders found among the initial non-respondents in this non-response survey. Significance tests were made using design-based methods because of this weighting and clustering of the data (Kish & Frankel, 1970; Koch & Lemeshow, 1972; Woodruff & Causey, 1976). More details about design and weighting procedures are reported elsewhere (Kessler, Little et al., 1995).

Machiavellian, narcissistic, and psychopathic traits are often viewed as negative or undesirable personality traits. However, recent research demonstrates that individuals with these traits possess qualities that may be personally beneficial within the business contexts. In this chapter, we conceptualize a balanced perspective of these traits throughout the entrepreneurial process (opportunity recognition, opportunity evaluation, and opportunity exploitation) and discuss human resources management strategies that can be employed to enhance the benefits, or minimize the challenges, associated with Machiavellian, narcissistic, and psychopathic traits. Specifically, we propose that Machiavellian qualities are most beneficial in the evaluation stage of entrepreneurship, and Machiavellian, narcissistic, and psychopathic qualities are beneficial in the exploitation stage of entrepreneurship.

Among psychiatric illnesses, genetically determined disorders usually have an early onset and a severe and complicated course. Gene–environmental interaction is of importance for aggressive impulsive behaviour. For example, alcoholism type II has a high family loading, a severe course, and is often associated with antisocial behaviour. In order to gain further understanding of aggressive and impulsive behaviour, genes determining serotonin metabolism, neurosteroids and carbohydrate metabolism should be of interest to investigate. Furthermore, modern brain-imaging studies will reveal the site of action of aggressiveness and impulsivity. Within brain regions of interest, biological studies will promote our knowledge of this deleterious behaviour.

There is limited research on the mental health of pregnant women in prison in England, mother and baby unit (MBU) applications and associated factors. Eighty-five pregnant women were interviewed in eight different prisons in England, UK. Schedules for the Clinical Assessment of Neuropsychiatry (SCAN) and Edinburgh Postnatal Depression Scale (EPDS) were used to assess mental health; Severity of Dependence Questionnaire (SOD-Q) for drug misuse; Alcohol Use Identification Test (AUDIT) for hazardous drinking and the Structured Clinical Interview for DSM-IV (SCID-II) to identify personality disorder. About 51% of participants had depression and 57% had anxiety. Those with prior social services involvement, diagnosis of personality disorder or history of suicidality were less likely to be admitted to MBUs. The high levels of depression and anxiety can have negative impacts on both the mother and her unborn child. Factors which influence MBU admission suggest those who might benefit most from MBU placement are least likely to be admitted. Other countries offer feasible alternatives to imprisonment for pregnant women and mothers which could be implemented in England.

Research in industrial and organizational psychology demonstrates that the regulation of negative emotions in response to both organizational stressors and interpersonal workplace interactions can result in functional and dysfunctional outcomes (Côté, 2005; Diefendorff, Richard, & Yang, 2008). Research on the regulation of negative emotions has additionally been conducted in social psychology, developmental psychology, neuropsychology, health psychology, and clinical psychology. A close reading of this broader literature, however, reveals that the conceptualization and use of the term “emotion regulation” varies within each research field as well as across these fields. The main focus of our chapter is to make sense of the term “emotion regulation” in the workplace by considering its use across a broad range of psychology disciplines. We then develop an overarching theoretical framework using disambiguating terminology to highlight what we argue are the important constructs involved in the process of intrapersonal emotion generation, emotional experience regulation, and emotional expression regulation in the workplace (e.g., emotional intelligence, emotion regulation strategies, emotion expression displays). We anticipate this chapter will enable researchers and industrial and organizational psychologists to identify the conditions under which functional regulation outcomes are more likely to occur and then build interventions around these findings.

The International Criminal Court has institutionalized the concept of individual responsibility for human rights violations. The jurisprudence of international criminal law has developed along with the institution. Affirmative defenses in the mitigation of punishment or avoidance of responsibility are becoming increasingly important in international criminal procedure. We contend that diminished culpability based on advances in neuroscience provides the most challenging set of choices for the international legal community. Of the variety of affirmative defenses, emerging neuroscience-based defense provide the most challenging set of choices for the international legal community. The Esad Landzo case at the ICTY brings these challenges into focus. We discuss the difficult choices the International Criminal Court will have to make to balance the rights and needs of the victims and the due process rights of the accused.
