Population Health and Environment (PHE) strategies are argued to improve ecosystem and human health by addressing family size and its effects on natural resource use, food security, and reproductive health. This study investigates men's views on a PHE family planning (FP) programme delivered among the pastoral Samburu tribe in rural northern Kenya. Three focus group discussions and nine semi-st...

Consensus constructs are a common topic in level-of-analysis research and, yet, leadership researchers have failed to consider their theoretical appeal as a contextual factor in the explanation of work-related attitudes and behaviors. Drawing on a sample of 27 naturally occurring occupational groups composed of 828 U.S. Air Force personnel, we examined the degree to which consensus in group mem...

Introduction. The relation between minute ventilation (VE) and carbon dioxide production (VCO(2)) can be characterised by the instantaneous ratio of ventilation to carbon dioxide production, the ventilatory equivalent for CO(2) (VEqCO(2)). We hypothesised that the time taken to achieve the lowest VEqCO(2) (time to VEqCO2 nadir) may be a prognostic marker in patients with chronic heart failure (...

BACKGROUND The high rates of dropout from exercise programs may be attributed in part to the poor ability of most individuals to accurately self-monitor and self-regulate their exercise intensity. The point of transition from aerobic to anaerobic metabolism may be an appropriate level of exercise training intensity as it appears to be effective and safe for a variety of populations. Possible pr...

Prior experience of fatiguing tasks is considered essential to establishing an optimal pacing strategy. This study examined the pacing behavior of inexperienced children during self-paced, 800 m running, both individually and within a competitive environment. Thirteen children (aged 9-11 y) completed a graded-exercise test to volitional exhaustion on a treadmill (laboratory trial), followed by ...

The kinetic theory is formulated with respect to anholonomic frames of reference on curved spacetimes. By using the concept of nonlinear connection we develop an approach to modelling locally anisotropic kinetic processes and, in corresponding limits, the relativistic non–equilibrium thermodynamics with local anisotropy. This lead to a unified formulation of the kinetic equations on (pseudo) Ri...

Following preliminary indications that in some individuals arm exercise enhanced rather than reduced simultaneous leg endurance, ten young men and women performed three forms of intermittent work to volitional exhaustion, under duty cycles of 45 s work, 15 s rest. The protocols were as follows: (A) knee extensions at 30% maximum voluntary contraction (MVC); (B) 30% MVC knee extensions combined ...

Compared with the large literature on subordinate employees, there are few studies of emotional exhaustion and turnover intention for organizational leaders. There is little research that has extended the job demands-resources (JD-R) model of emotional exhaustion to leaders. In this study, the authors adapted the JD-R framework to analyze data collected from a sample of 410 leaders of addiction...

Reliability theory is a general theory about systems failure. It allows researchers to predict the age-related failure kinetics for a system of given architecture (reliability structure) and given reliability of its components. Reliability theory predicts that even those systems that are entirely composed of non-aging elements (with a constant failure rate) will nevertheless deteriorate (fail m...

Objectives. The global burden of burnout cost is in excess of $300 billion annually. Locally, just under half of working Australians experience high levels of occupational burnout. Consequently, burnout interventions are paramount to organisational productivity. Exercise has the potential to provide a multilevel and cost effective burnout intervention. The current study aims to extend the liter...
