Subjective health complaints and health related quality of life in a population of health care workers

The aim of this study was to assess whether Subjective Health Complaints (SHC), demands and coping are associated with health-related quality of life in a population of health care workers. One hundred and nineteen employees in two nursing homes for the elderly filled in a questionnaire on health, exercise, psychological factors, and work conditions. Main outcome measures were SHC and quality of life measured by SF-36. High level of SHC was associated to low health-related quality of life. Low coping and high demands were related to low scores (low quality of life), and high coping and low demands to high scores on mental health. Pseudoneurological complaints (e.g. tiredness, sadness), high demands and low coping were associated with low mental health. The expected negative association between SHC and health-related quality of life was found. There was a positive association between coping and quality of life.     

“Economic Crisis and Poaching: Advice on Anti-Poaching Management from The Galician Shellfish Sector”

ABSTRACT

The aim of this work is to prove the significant relationship between the economic crisis and the increase of the shellfish poaching in Galicia (NW Spain) during the period 2008–2012. A relationship was observed between the “necessity” causes and the economic incentives as an explanation for shellfish poaching. The results achieved pointing out the importance to complete the coercive dissuasive methods in the fight against poaching using informal management mechanisms implemented in Galician shellfish communities, especially in co-managed contexts in which unemployment and necessity processes are identified.     

TMS suppression of right pars triangularis, but not pars opercularis, improves naming in aphasia

This study sought to discover if an optimum 1 cm² area in the non-damaged right hemisphere (RH) was present, which could temporarily improve naming in chronic, nonfluent aphasia patients when suppressed with repetitive transcranial magnetic stimulation (rTMS). Ten minutes of slow, 1 Hz rTMS was applied to suppress different RH ROIs in eight aphasia cases. Picture naming and response time (RT) were examined before, and immediately after rTMS. In aphasia patients, suppression of right pars triangularis (PTr) led to significant increase in pictures named, and significant decrease in RT. Suppression of right pars opercularis (POp), however, led to significant increase in RT, but no change in number of pictures named. Eight normals named all pictures correctly; similar to aphasia patients, RT significantly decreased following rTMS to suppress right PTr, versus right POp. Differential effects following suppression of right PTr versus right POp suggest different functional roles for these regions.     

Childhood correlates of adult levels of incongruence between implicit and explicit motives

The present study used archival longitudinal data from 5 years old children and their mothers to explore mother and child characteristics associated with motive incongruence 26 years later. Motive incongruence was assessed in terms of discrepancies between implicit and explicit measures of the need for achievement, power and affiliation. Previous research has suggested that trait self-determination, which involves self-awareness and perceived volition in one’s actions, moderates the level of implicit/explicit motive incongruence. We hypothesized that early childhood experiences that interfere with the development of self-determination would be associated with later motive incongruence. Our results showed that childhood factors that reflected mother–child difficulties in the areas of autonomy and relatedness were significantly related to adult levels of motive incongruence. Specifically, adult motive incongruence was significantly associated with strong maternal inhibition of the child’s dependent and sexual impulses, maternal separation during the child’s second year, and mother reports of feeling dominated by the child. Limitations of the data are discussed.     

Detecting conscious awareness from involuntary autonomic responses

Can conscious awareness be ascertained from physiological responses alone? We evaluate a novel learning-based procedure permitting detection of conscious awareness without reliance on language comprehension or behavioural responses. The method exploits a situation whereby only consciously detected violations of an expectation alter skin conductance responses (SCRs). Thirty participants listened to sequences of piano notes that, without their being told, predicted a pleasant fanfare or an aversive noise according to an abstract rule. Stimuli were presented without distraction (attended), or while distracted by a visual task to remove awareness of the rule (unattended). A test phase included occasional violations of the rule. Only participants attending the sounds reported awareness of violations and only they showed significantly greater SCR for noise occurring in violation, vs. accordance, with the rule. Our results establish theoretically significant dissociations between conscious and unconscious processing and furnish new opportunities for clinical assessment of residual consciousness in patient populations.     

Repeatedly reactivated memories become more resistant to hippocampal damage

We examined whether repeated reactivations of a context memory would prevent the typical amnesic effects of post-training damage to the hippocampus (HPC). Rats were given a single contextual fear-conditioning session followed by 10 reactivations, involving a brief return to the conditioning context (no shock). Subsequently, the rats received sham or complete lesions of the HPC. When tested for retention, the HPC rats that experienced the reactivations froze significantly more than nonreactivation HPC rats and did not significantly differ from their respective control group. These findings suggest that memory reactivations contribute to long-term memories becoming independent of the HPC.     

In praise of "false" models and rich data

The authors argue that "true" models that aim at faithfully mimicking or reproducing every property of the sensorimotor system cannot be compact as they need many free parameters. Consequently, most scientists in motor control use what are called "false" models--models that derive from well-defined approximations. The authors conceptualize these models as a priori limited in scope and approximate. As such, they argue that a quantitative characterization of the deviations between the system and the model, more than the mere act of falsifying, allows scientists to make progress in understanding the sensorimotor system. Ultimately, this process should result in models that explain as much data variance as possible. The authors conclude by arguing that progress in that direction could strongly benefit from databases of experimental results and collections of models.     

Changes in Anabolic and Catabolic Activity among Women Taking Part in an Alternative Labour Market Programme

Thirty-two female participants in a mobilising labour market programme offering temporary, alternative employment in Sweden were followed longitudinally for one year, including a six month post participation follow-up period. It can be hypothesised that an important aspect of the physiological effects of unemployment is a change in the balance between anabolic and catabolic activities in the body and that re-employment should lead to a shift towards anabolism. An earlier study of a smaller subset of the data, however, including both men and women, showed increased prolactin and decreased dehydroepiadrosterone sulphate (DHEA-s) levels, contrary to the initial hypothesis. In the present analysis, intended to elucidate these results, psychophysiological data were summarised in two indices, one connected with anabolism (made up of testosterone and DHEA-s) and one with catabolism (prolactin, gamma-glutamyl transferase, aspartate amino transferase, alpha levuline amino transferase, and body mass index). In addition, self-rated anxiety, depression, hopelessness and personal control were analysed. The results indicate that the effect of 'better' activities within the programme was a temporary increase in anabolism, possibly indicating lower stress levels, and the effect of 'worse' activities, on the one hand, a temporary decrease in the catabolic index, probably reflecting repressed alcohol consumption, and, on the other hand, impaired anabolism. There was also a general but transient decrease in depressiveness measured by the Hospital Anxiety and Depression Scale. The results seem to imply that it is difficult to achieve lasting effects through a relatively short participation in a mobilising programme.
