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.     

Dialogue Police,Decision Making,and the Management of Public Order During Protest Crowd Events

Following the major riots within England in August 2011, the efficacy of public order police decision making was brought into a sharp focus. None the less, the reform of this mode of policing within the UK was already underway with a strong emphasis upon policing through consent and the need to facilitate peaceful protest through dialogue and communication. This paper reports upon a critical ‘test case’ for this ‘new approach’ by analysing the policing of a series of protests against Government policy across 3 days that surrounded a Government party conference in Sheffield, a large city in the north of England. This paper draws out lessons to be learned from what proved to be a highly successful dialogue‐based approach to policing protests. We contend that dialogue and liaison were effective because they allowed for an ongoing dynamic risk assessment that improved command‐level decision making and enhanced police proportionality. The subsequent impact upon crowd dynamics allowed for an improved capacity for proactive public order management, encouraged ‘self‐regulation’ in the crowd, and avoided the unnecessary police use of force at moments of tension. The implications of the analysis for theory and practice are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

“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.
