Performance, personality, and energetics : correlation, causation, and mechanism

The study of phenotypic evolution should be an integrative endeavor that combines different approaches and crosses disciplinary and phylogenetic boundaries to consider complex traits and organisms that historically have been studied in isolation from each other. Analyses of individual variation within populations can act to bridge studies focused at the levels of morphology, physiology, biochemistry, organismal performance, behavior, and life history. For example, the study of individual variation recently facilitated the integration of behavior into the concept of a pace-of-life syndrome and effectively linked the field of energetics with research on animal personality. Here, we illustrate how studies on the pace-of-life syndrome and the energetics of personality can be integrated within a physiology-performance-behavior-fitness paradigm that includes consideration of ecological context. We first introduce key concepts and definitions and then review the rapidly expanding literature on the links between energy metabolism and personality traits commonly studied in nonhuman animals (activity, exploration, boldness, aggressiveness, sociability). We highlight some empirical literature involving mammals and squamates that demonstrates how emerging fields can develop in rather disparate ways because of historical accidents and/or particularities of different kinds of organisms. We then briefly discuss potentially interesting avenues for future conceptual and empirical research in relation to motivation, intraindividual variation, and mechanisms underlying trait correlations. The integration of performance traits within the pace-of-life-syndrome concept has the potential to fill a logical gap between the context dependency of selection and how energetics and personality are expected to interrelate. Studies of how performance abilities and/or aspects of Darwinian fitness relate to both metabolic rate and personality traits are particularly lacking.

Corticomotor responses to attentionally demanding motor performance: a mini-review

Increased attentional demand has been shown to reduce motor performance, leading to increases in accidents, particularly in elderly populations. While these deficits have been well documented behaviorally, their cortical correlates are less well known. Increased attention has been shown to affect activity in prefrontal regions of the cortex. However there have been varying results within past research investigating corticomotor regions, mediating motor performance. This mini-review initially discusses past behavioral research, before moving to studies investigating corticomotor areas in response to changes in attention. Recent dual task studies have revealed a possible decline in the ability of older, but not younger, adults to activate inhibitory processes within the motor cortex, which may be correlated with poor motor performance, and thus accidents. A reduction in cortical inhibition may be caused by neurodegeneration within prefrontal regions of the cortex with age, rendering older adults less able to allocate attention to corticomotor regions.

Construction and regulation of “dangerous consumptions” : re-regulating state casino capitalism - an Australian regulatory case study

This paper explores insights into the regulatory state and state capitalism through the lens of how states construct and regulate markets in the area of ‘dangerous consumptions’, in particular, land-based casino gambling. It focuses on what is needed for public interest regulation; with a focus on consumer protection and harm prevention. Gambling constitutes a site of explicit state regulation as the state decides and negotiates license-to-operate conditions along with the degree of significance accorded to impact/harm, regulatory monitoring and enforcement, harm prevention and state/operator duty of care...

Occupational safety in China: safety climate and its influence on safety-related behavior

The improvement of health and safety standards within the organizational context is an important issue of global concern. China’s occupational health and safety (OHS) has increasingly drawn national and international attention as it has not kept pace with its globalization of production and trade. The traditional approach to managing workplace safety in China has focused on the technical aspects of engineering systems and processes, and it has attributed the majority of workplace accidents and injuries to unsafe working conditions instead of the unsafe work practices of employees. However, there has been a fundamental shift in the safety management research carried out in many countries and across diverse industries, which aims to measure the impact of attitudinal, organizational, cultural, and social dimensions on occupational safety. This article examines the relationship between safety climate and safety-related behavior in the Chinese context and draws implications for the management of occupational safety in China.

Association between attributions of responsibility for motor vehicle crashes, depressive symptoms, and return to work.

Perceptions surrounding the underlying causes of accidents and injuries may be a key mechanism influencing postaccident health and functional outcomes among people injured in road crashes. In particular, attributions of responsibility may influence rates of postcrash depressive symptomatology and return-to-work.
