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.

Surveying hard-to-reach groups is difficult but necessary to prevent selection effects and biased sampling. Their diversity makes it difficult to recommend efficient solutions because they bring challenges that are specific to each group. Among these are limited ability in official languages, literacy problems, physical or mental disabilities or the particularities of subgroups such as ethnic, religious and cultural minorities, adolescents and the elderly. Drawing notably on lessons from migration research, this paper reviews the contemporary issues associated with five sets of circumstances that may result in groups being unreached by transport surveys.

Health scientists and urban planners have long been interested in the influence that the built environment has on the physical activities in which we engage, the environmental hazards we face, the kinds of amenities we enjoy, and the resulting impacts on our health. However, it is widely recognized that the extent of this influence, and the specific cause-and-effect relationships that exist, are still relatively unclear. Recent reviews highlight the need for more individual-level data on daily activities (especially physical activity) over long periods of time linked spatially to real-world characteristics of the built environment in diverse settings, along with a wide range of personal mediating variables. While capturing objective data on the built environment has benefited from wide-scale availability of detailed land use and transport network databases, the same cannot be said of human activity. A more diverse history of data collection methods exists for such activity and continues to evolve owing to a variety of quickly emerging wearable sensor technologies. At present, no “gold standard” method has emerged for assessing physical activity type and intensity under the real-world conditions of the built environment; in fact, most methods have barely been tested outside of the laboratory, and those that have tend to experience significant drops in accuracy and reliability. This paper provides a review of these diverse methods and emerging technologies, including biochemical, self-report, direct observation, passive motion detection, and integrated approaches. Based on this review and current needs, an integrated three-tiered methodology is proposed, including: (1) passive location tracking (e.g., using global positioning systems); (2) passive motion/biometric tracking (e.g., using accelerometers); and (3) limited self-reporting (e.g., using prompted recall diaries). Key development issues are highlighted, including the need for proper validation and automated activity-detection algorithms. The paper ends with a look at some of the key lessons learned and new opportunities that have emerged at the crossroads of urban studies and health sciences.

We do have a vision for a world in which people can walk to shops, school, friends' homes, or transit stations; in which they can mingle with their neighbors and admire trees, plants, and waterways; in which the air and water are clean; and in which there are parks and play areas for children, gathering spots for teens and the elderly, and convenient work and recreation places for the rest of us.

With significant changes in the aviation industry, various airport–airline arrangements have been formed to achieve alternative objectives. However, no consensus has been reached on such arrangements’ economic effects and the associated optimal public policy. This chapter aims to provide an interpretive review of the common types of airport–airline arrangements, the different modeling approaches used and key conclusions reached by recent studies. Our review suggests that airport–airline arrangements can take diverse forms and have been widely used in the industry. They may allow the airport and its airlines to internalize demand externality, increase traffic volume, reduce airport investment risks and costs, promote capacity investment, enhance service quality, or simply are a response to the competition from other airport–airline chains. On the other hand, such vertical arrangements, especially for those exclusively between airports and selected airlines, could lead to collusive outcomes at the expenses of non-participating organizations. The effects of such arrangements are also significantly influenced by the contract type, market structure and bargaining power between the airport and airline sectors. While case by case investigations are often needed for important economic decisions, we recommend policy-makers to promote competition in the airline and airport segments whenever possible, and demand more transparency or regulatory reporting of such arrangements. Policy debates and economic studies should be carried out first, before intrusive regulations are introduced.

The higher education world around us is changing fast. Mobile learning (M-learning) and apps in education are new and exciting. However, this does not mean that the faculty is less relevant. On the contrary, the faculty are an ever-important factor that is needed to increase student engagement. Disengaged students are in fact more problematic than low achieving students. This is because of the disruption disengaged student bring in the classroom. Therefore, increasing student engagement is a key challenge in higher education today. Research suggests that active learning, value and expectations are important factors that determine student engagement. Some of these factors can be indirectly influenced by the faculty and course designers. Against this background, the objective of this chapter is to examine if dwindling student engagement in higher education can be addressed with CURPA, i.e. a CURriculum and course planning (CURP) App. CURPA is the result of our efforts at Utrecht University to help design courses and curricula by using cards to account for different activities, with the strategic aim being to stimulate student engagement in higher education. Our expert interviews resulted in a MoSCoW-prioritised list of requirements that can be implemented over time, structured in line with Becker's student engagement model.

The role of dark side personality characteristics in the workplace has received increasing attention in the organizational sciences and from leadership researchers in particular. We provide a review of this area, mapping out the key frameworks for assessing the dark side. We pay particular attention to the roles that the dark side plays in leadership processes and career dynamics, with special attention given to destructive leadership. Further, we examine the role that stress plays in the emergence of leaders and how the dark side plays into that process. We additionally provide discussion of the possible roles that leaders can play in producing stress experiences for their followers. We finally illustrate a dynamic model of the interplay of dark leadership, social relationships, and stress in managerial derailment. Throughout, we emphasize a functionalist account of these personality characteristics, placing particular focus on the motives and emotional capabilities of the individuals under discussion.

The purpose of this chapter is to review how well walking interventions have increased and sustained walking, and to provide suggestions for improving future walking interventions. A scoping review was conducted of walking interventions for adults that emphasised walking as a primary intervention strategy and/or included a walking outcome measure. Interventions conducted at the individual, community, and policy levels between 1990 and 2015 were included, with greater emphasis on recent interventions. Walking tends to increase early in interventions and then gradually declines. Results suggest that increased walking, and environmental-change activities to support walking are more likely to be sustained when they are immediately followed by greater economic benefits/time-savings, social approval, and/or physical/emotional well-being. Adaptive interventions that adjust intervention procedures to match dynamically changing environmental circumstances also hold promise for sustaining increased walking. Interventions that incorporate automated technology, durable built environment changes, and civic engagement, may increase cost-efficiency. Variations in outcome measures, study duration, seasons, participant characteristics, and possible measurement reactivity preclude causal inferences about the differential effectiveness of specific intervention procedures for increasing and sustaining walking. This review synthesises the effects of diverse walking interventions on increasing and sustaining walking over a 25-year period. Suggestions are provided to guide future development of more effective, sustainable walking interventions at the population level.
