Crime and violence in Brazil: Systematic review of time trends,prevalence rates and risk factors

Between 1980 and 2010 there were 1 million homicides in Brazil. Dramatic increases in homicide rates followed rises in inequality, more young men in the population, greater availability of firearms, and increased drug use. Nevertheless, disarmament legislation may have helped reduce homicide rates in recent years. Despite its very high rate of lethal violence, Brazil appears to have similar levels of general criminal victimization as several other Latin American and North American countries. Brazil has lower rates of drug use compared to other countries such as the United States, but the prevalence of youth drug use in Brazil has increased substantially in recent years. Since 1990, the growth of the Brazilian prison population has been enormous, resulting in the fourth largest prison population in the world. Through a systematic review of the literature, we identified 10 studies assessing the prevalence of self-reported offending in Brazil and 9 studies examining risk factors. Levels of self-reported offending seem quite high among school students in Brazil. Individual and family-level risk factors identified in Brazil are very similar to those found in high-income countries.     

Job Satisfaction and Domains of Job Satisfaction for Older Workers with Disabilities in Europe

This paper analyzes the levels of job satisfaction reported by older workers (aged 50–64) with and without disability by using an aggregating approach in which job satisfaction is seen as a combination of various job satisfaction domains (physical effort, time pressure, level of freedom, capability to develop new skills, support in the workplace, recognition of the work, salary, promotion prospect and job security). Using the Survey of Health, Ageing and Retirement in Europe, we estimate a two-layer model based on the interrelation between the different domains of job satisfaction and wherein the individual’s overall job satisfaction depends on each of these domains. The results show that the levels of satisfaction with the recognition of the work, support in difficult situations and physical effort have a significant effect on the overall job satisfaction reported by limited disabled workers. For this group, the trade-offs between the domains recognition with work and support and satisfaction with salary are especially high. These findings can help organizations, managers and policy makers to design or modify current jobs to make them more attractive in terms of satisfaction for limited disabled older workers.     

Spontaneously Hypertensive Rats: Possible Animal Model of Sleep-Related Movement Disorders

Clinical experience suggests that restless legs syndrome (RLS), periodic leg movement (PLM), and attention-deficit hyperactivity disorder (ADHD) may co-occur in both children and adults. The purpose of the present study was to provide an electrocorticography and electromyography evaluation of the spontaneously hypertensive rat (SHR) to investigate the potential of this rat strain as an animal model of RLS–PLM. Initial work focused on evaluating sleep patterns and limb movements during sleep in SHR, having normotensive Wistar rats (NWR) as control, followed by comparison of two treatments (pharmacological–dopaminergic agonist treatment and nonpharmacological–chronic physical exercise), known to be clinically beneficial for sleep-related movement disorders. The captured data strengthen the association between SHR and RLS–PLM, revealing a significant reduction on sleep efficiency and slow wave sleep and an increase on wakefulness and limb movements for the SHR group during the dark period, as compared to the NWR group, effects that have characteristics that are strikingly consistent with RLS–PLM. The pharmacological and nonpharmacological manipulations validated these results. The present findings suggest that the SHR may be a useful putative animal model to study sleep-related movement disorders mechanisms.

Who benefits from independent careers? Employees,organizations, or both?

The traditional organizational career has been depicted as the classic example of how employers and employees can develop a mutually beneficial relationship; but changes in the competitive landscape and in individual work values have challenged its viability. Commentators have argued that a ‘new career’ deal, encapsulated by the notions of the protean and the boundaryless career, has emerged suggesting a shift in control of careers from organizations to individuals. Research has explored the implications for individuals' careers while largely neglecting consequences for organizations. Our paper seeks to remedy this by exploring both the individual and the organizational outcomes of independent career orientations and the extent to which organizations can manage these through high commitment human resource management (HRM) practices. Our study, conducted with 655 employee–supervisor dyads, indicates that a protean career orientation results in gains for both employees and organizations, whereas a boundaryless career orientation is associated with mutual losses. In addition, our findings suggest that high commitment HR practices play an important role in managing the outcomes of employees seeking traditional careers but have only a limited impact on those with a boundaryless career orientation.
