Human performance, particularly that of the warfighter, has been the subject of a large amount of research during the past few decades. For example, in the Medline database of medical and psychological research, 1,061 papers had been published on the topic of “military performance” as of October 2003. Because warfighters are often pushed to physiological and mental extremes, a study of their performance provides a unique glimpse of the interplay of a wide variety of intrinsic and extrinsic factors on the functioning of the human brain and body. Unfortunately, it has proven very difficult to build performance models that can adequately incorporate the myriad of physiological, medical, social, and cognitive factors that influence behavior in extreme conditions. The chief purpose of this chapter is to provide a neurobiological (neurochemical) framework for building and integrating warfighter performance models in the physiological, medical, social, and cognitive areas. This framework should be relevant to all other professionals who routinely operate in extreme environments. The secondary purpose of this chapter is to recommend various performance metrics that can be linked to specific neurochemical states and can accordingly strengthen and extend the scope of the neurochemical model.

Consistent exposure to sunshine with high ultraviolet values has significant negative effects on human skin. Key risks include melanoma and the rapid onset of signs of ageing. For Chinese, these are viewed as undesirable, because their genetic legacy predisposes them to greater numbers of skin blemishes and because darker shades are culturally and socially viewed as less attractive. Properties in sunshine locations may need to modify aspects of their infrastructure and service delivery to meet the needs of the globally influential Chinese market. Shaded spaces, new activities, scheduling of experiences in the early morning, evening and at night, are all a part of the required innovations in experience design.

Purpose – Examined here are some of the tenets of social capital in the context of the migrants’ crossing the U.S.–Mexico border without official authorization. Using this context helps identify how social capital development is weakened by the structural and gendered dimensions of migration, contributing to the rise in undocumented border crosser deaths since 1993.

Approach – A selection of published works provide an overview of social capital, and in particular, how the framework has been used to further our understanding of the process of migration and immigrant settlement in new destinations. The principles of social capital are then examined in light of women's border crossing experiences and used to argue that migrants from emerging migrant-sending states in southern and central Mexico have had less time to accumulate resource-enhancing migration-related social capital. The narratives of repatriated women collected during research on the border in 2006–2007 are used to illustrate how controlling environments undermine the acquisition of social capital at a critical time.

Findings – The selection of narratives of women who were repatriated after attempting to cross into the United States without authorization illustrate the perilous interplay of hardening border enforcement and multiplying illicit border smuggling organizations. The outcome is the downward leveling of social capital on the border that potentially poses greater life-threatening risks for migrants.

Originality/value – This study provides a theoretical understanding that can be used to explain rising levels of violence along the U.S.–Mexico border that increasingly engulf migrants fleeing poverty in Mexico.

Approximately 1,750–2,000 children die in the United States annually because of child abuse or neglect. Official statistics show that women are more often the perpetrators of abuse and neglect-related deaths, even though child welfare professionals largely attribute these deaths to men. Either acting alone or with another individual, mothers are responsible for roughly 60% of deaths and either together or alone, fathers are responsible for roughly 40% of deaths. Despite the consistency of this information, it is not widely accepted by child welfare workers – the professional group whose job it is to identify risk factors and to protect children from harm. Previous research shows that workers are more likely to believe that men are responsible for children’s deaths and that deaths are perpetrated by non-family members. In this chapter, we explore the potential explanations for workers’ misperceptions including the role of gender norms, ideology, confusion concerning how children die, and also which kinds of cases result in criminal charges and thus, shape the public’s understanding of fatal child maltreatment. Incomplete and inadequate information about the perpetration of maltreatment deaths potentially puts children at risk for future fatalities. Implications for child welfare and social service professionals, their training, and practice are discussed.

Purpose – Adaptation to climate change requires that the population at risk and decision makers in various sectors become aware of the possible detrimental impacts in order to take whatever action is needed, especially in highly vulnerable countries and regions. In order to assess the climate change and impact awareness in a particularly vulnerable area – the Indian city Hyderabad, located within a semiarid region – we wanted to learn more about the local climate discourse, in particular the daily newspaper coverage of climate change and weather extremes.

Methodology/approach – After having looked at the Indian climate change discourse (CCD) in general, based on literature review, we were studying the local public CCD, based on the in-depth analysis of two English language daily newspapers, and three Telugu (the dominant local language) daily newspapers, covering the period of 2008–2009. This qualitative and quantitative analysis was completed by two expert interviews with local journalists.

Findings – We find that the more recent Indian CCD has shifted if compared to the dominant argumentation pattern of the period before, as reported in other analyses. While the former discourse was characterized by the scheme “the poor/developing countries suffer from anthropogenic climate change caused by the industrialized countries,” the recent Indian CCD has become more differentiated, taking into account both impacts elsewhere, and, most notably, conceding a (limited) responsibility of countries like India. On a local level, while reports on weather extremes are very common, we find that local newspapers of Hyderabad do not provide a link between these extreme events and (global) climate change.

Research limitations – Our discourse analysis could only cover a short time period of a local CCD, leaving open the questions of (a) its further development, and (b) how things might stand in other places in India. Furthermore it would be necessary to complement our study by analyses of the impact of mass media reporting on people's attitudes and behavior.

Originality/value of paper – Given the importance of public participation in adaptation measures, it is crucial to know if and how the wider public and the majority of the nonexpert public administration (which needs to be involved) understands the causes, potential impacts, and possible adaptive action in the face of climate change. This chapter provides a necessary (though not sufficient) element for that assessment. The findings can help to identify weaknesses, and thus to give hints how to improve the adaptive capacity in places like Hyderabad (India).

Immigration enforcement along the Southwest border between United States and Mexico has long channeled migrants into perilous desert corridors, where many thousands have died, out of general public view. In response to this humanitarian crisis, activists from organizations such as No More Deaths (NMD) trek deep into the treacherous desert, hoping to save lives, honor the remains of those who did not survive, and influence public opinion about border enforcement policies. NMD’s activism is not merely utilitarian but also deeply expressive; ultimately, they hope to convey the message that all lives – including those of unauthorized migrants – are worth saving. The Trump Administration has escalated repressive tactics intended to silence these forms of border-policy dissent. Some federal land managers now blacklist NMD, preemptively denying requests for access permits. Meanwhile, the US Attorney’s office has aggressively prosecuted members for humanitarian activities. This chapter explains the expressive components of humanitarian activism in this context and of the government’s attempt to suppress it, suggesting the need for constitutional scrutiny and legal change.

Understanding how health status and physiological factors affect performance is a daunting task. This chapter will discuss physiological, behavioral, and psychological factors that influence or determine the capacity to fight, and will consider metrics that can be used to measure their status. The premise of this discussion is that there is a set of physiological and psychological factors that intimately affect performance and that the relative contribution of these variables is individually unique. These factors can be identified and assessed, and are amenable to modification. A fuller understanding of these variables can lead the effort to maintain and improve performance in the adverse and challenging environments of military operations.
