The Neolithic and Bronze Ages were highly transformative periods for the genetic history of Europe but for the Aegean-a region fundamental to Europe's prehistory-the biological dimensions of cultural transitions have been elucidated only to a limited extent so far. We have analysed newly generated genome-wide data from 102 ancient individuals from Crete, the Greek mainland and the Aegean Islands, spanning from the Neolithic to the Iron Age. We found that the early farmers from Crete shared the same ancestry as other contemporaneous Neolithic Aegeans.

However, recent archaeogenetic research forces us to rethink models regarding the role of infectious diseases in past societal trajectories. The plague bacterium Yersinia pestis, which was involved in some of the most destructive historical pandemics, circulated across Eurasia at least from the onset of the 3 millennium BCE, but the challenging preservation of ancient DNA in warmer climates has restricted the identification of Y.

The origins of the Bronze Age Minoan and Mycenaean cultures have puzzled archaeologists for more than a century. We have assembled genome-wide data from 19 ancient individuals, including Minoans from Crete, Mycenaeans from mainland Greece, and their eastern neighbours from southwestern Anatolia. Here we show that Minoans and Mycenaeans were genetically similar, having at least three-quarters of their ancestry from the first Neolithic farmers of western Anatolia and the Aegean, and most of the remainder from ancient populations related to those of the Caucasus and Iran.

Conclusions: The strengths of the psychiatry training program at St Vincent's Hospital are the high rate of recruitment of junior medical officers to psychiatry training, the provision of quality in-house teaching, the in-house provision of psychotherapy supervision and exam preparation, the positive influence of the chief psychiatry registrar, having enough trainees to alleviate the tension between training and service delivery, and the availability of a variety of 'extra', high-quality, professional development opportunities.
This paper summarizes the findings for the Australasia and Pacific Region of the WPA Task Force on Steps, Obstacles and Mistakes to Avoid in the Implementation of Community Mental Health Care. We present an overview of mental health services in the region; discuss policies, plans and programmes; chart progress towards achieving community-oriented services, and detail the lessons learned.

Empirical data presented here question this as they show that subjects' choices of distinct views of objects are not mutually concordant. This being so, it seems unlikely that a facsimile representation of a solid yields a full description of the process of representation.

This commentary considers the paper by Furley and Memmert (2010) who sought to test the respective validities of the specific processing and cognitive adaptation hypotheses. That they found no evidence of a difference between experienced basketball players and nonathletes on the Corsi block task, a measure of spatial memory, led them to infer support for the specific processing hypothesis, namely that differences between experts and novices manifest themselves only in processes related specifically to the domain of expertise. An alternative interpretation is offered, indicating possible confounds and referring to recent research that suggests Corsi block and dynamic spatial tasks depend upon different neuronal networks.

The Multiple-Object Tracking paradigm has most commonly been utilized to investigate how subsets of targets can be tracked from among a set of identical objects. Recently, this research has been extended to examine the function of featural information when tracking is of objects that can be individuated. We report on a study whose findings suggest that, while participants can only hold featural information for roughly two targets this task does not affect tracking performance detrimentally and points to a discontinuity between the cognitive processes that subserve spatial location and featural information.

It is timely to consider the types of MHC which exist in different countries, their characteristics which may contribute to making them more effective, and any possible limitations and concerns raised about them.
Recent Findings: The emerging literature on MHCs indicates, particularly with the wider types of MHCs, that they may contribute to the substantial enhancement of mental health resources and sustainability of services; mental health reform is much more likely to be implemented properly with an independent monitor such as a MHC which has official influence at the highest levels of government; and they can encourage, champion and monitor the transformation of services into more evidence-based, community-centred, recovery-oriented, consumer, family and human rights-focused mental health services.
This paper provides guidance on the steps, obstacles and mistakes to avoid in the implementation of community mental health care. The document is intended to be of practical use and interest to psychiatrists worldwide regarding the development of community mental health care for adults with mental illness. The main recommendations are presented in relation to: the need for coordinated policies, plans and programmes, the requirement to scale up services for whole populations, the importance of promoting community awareness about mental illness to increase levels of help-seeking, the need to establish effective financial and budgetary provisions to directly support services provided in the community.

We endeavour to elucidate whether this is a consequence of a painterly usage or a perceptual effect and conclude, on the basis of empirical evidence, that the latter cause is more likely.

Methods: The literature on the treatment and care of medical practitioner impairment due to mental illness, and substance use, with special reference to impaired psychiatrists is briefly reviewed. The implications of deficiencies of usual clinical management of doctors impaired by mental illness and opportunities for improvement in services for them are explored, including the impact of the experience of being an impaired medical practitioner under psychiatric treatment.
Objective: This paper will define and describe impairment in medical practitioners due to mental illness, with special reference to the specialty of psychiatry, and then review the prevalence and identification of impaired practitioners.
Methods: The quantitative and qualitative evidence regarding the incidence and impact of medical practitioner impairment due to mental illness (and, to some extent, substance use), with special reference to impaired psychiatrists, is reviewed.
Results: Medical practitioner impairment due to mental illness has a severe impact on their lives and their families due to both the effects of the disorder and the experience of communal, professional and self stigma.

In the present experiments, hemispatial size bias was measured through simultaneous presentation of a circle and an ellipse varying in horizontal or vertical extent. A consistent leftward bias of horizontal size judgments (but not vertical) was obtained; at the point of subjective equality, the width of the objects that were presented in left hemispace was smaller than the width of the objects that were presented in right hemispace.

For elements that should be visible from the participants' viewpoint, more elements were reported from the left side of the image than from the right, irrespective of view. These results establish that there is a lateralized bias in reporting the details in mental images--representational pseudoneglect.

The research suggests that after designated targets within the visual field have attracted preattentive indexes that point to their locations in space, conscious processes, vulnerable to secondary visual and spatial task interference, form deliberate strategies beneficial to the tracking task, before tracking commences. Target tracking itself is realized by central executive processes, which are sensitive to any other cognitive demands.
