Rehabilitation of executive functions: Implications and strategies

Executive Functions (EF) concern a range of abilitiesincluding problem-solving, planning, initiation, selfmonitoring,conscious attention, cope with new situationsand the ability to modify plans if necessary. It’s ahigh cognitive function that is crucial for a person to getengaged and maintain daily activities whilst keeping agood quality of life. Problems in the EF were formerlyknown as Dysexecutive Syndrome (DS). There are manymodels concerning DS, although the literature on thesubject still remains unclear. Several works appoint theeffects brought by elderly life, as well as abuse of drugsand some psychopathologies. These factors are knownto increase the distress of the frontal circuits and thatcould be associated to executive deficits. The effects ofDS would compromise individuals in day-to-day routine,academic, social and labor fields. There is a growingbody of studies trying to determine the causes, implications,associations and the best way to take care of theseeffects. This work intends to review DS, focusing on themost important fields related to this area, such as psychopathologyassociations, cognitive reserve, assessmentand cognitive rehabilitation programs.

Northern hemisphere winter atmospheric climate: modes of natural variability and climate change

Under anthropogenic climate change it is possible that the increased radiative forcing and associated changes in mean climate may affect the “dynamical equilibrium” of the climate system; leading to a change in the relative dominance of different modes of natural variability, the characteristics of their patterns or their behavior in the time domain. Here we use multi-century integrations of version three of the Hadley Centre atmosphere model coupled to a mixed layer ocean to examine potential changes in atmosphere-surface ocean modes of variability. After first evaluating the simulated modes of Northern Hemisphere winter surface temperature and geopotential height against observations, we examine their behavior under an idealized equilibrium doubling of atmospheric CO2. We find no significant changes in the order of dominance, the spatial patterns or the associated time series of the modes. Having established that the dynamic equilibrium is preserved in the model on doubling of CO2, we go on to examine the temperature pattern of mean climate change in terms of the modes of variability; the motivation being that the pattern of change might be explicable in terms of changes in the amount of time the system resides in a particular mode. In addition, if the two are closely related, we might be able to assess the relative credibility of different spatial patterns of climate change from different models (or model versions) by assessing their representation of variability. Significant shifts do appear to occur in the mean position of residence when examining a truncated set of the leading order modes. However, on examining the complete spectrum of modes, it is found that the mean climate change pattern is close to orthogonal to all of the modes and the large shifts are a manifestation of this orthogonality. The results suggest that care should be exercised in using a truncated set of variability EOFs to evaluate climate change signals.

An assessment of the benefits and limitations of the shamba agroforestry system in Kenya and of management and policy requirements for its successful and sustainable reintroduction

The shamba system involves farmers tending tree saplings on state-owned forest land in return for being permitted to intercrop perennial food crops until canopy closure. At one time the system was used throughout all state-owned forest lands in Kenya, accounting for a large proportion of some 160,000 ha. The system should theoretically be mutually beneficial to both local people and the government. However the system has had a chequered past in Kenya due to widespread malpractice and associated environmental degradation. It was last banned in 2003 but in early 2008 field trials were initiated for its reintroduction. This study aimed to: assess the benefits and limitations of the shamba system in Kenya; assess the main influences on the extent to which the limitations and benefits are realised and; consider the management and policy requirements for the system's successful and sustainable operation. Information was obtained from 133 questionnaires using mainly open ended questions and six participatory workshops carried out in forest-adjacent communities on the western slopes of Mount Kenya in Nyeri district. In addition interviews were conducted with key informants from communities and organisations. There was strong desire amongst local people for the system's reintroduction given that it had provided significant food, income and employment. Local perceptions of the failings of the system included firstly mismanagement by government or forest authorities and secondly abuse of the system by shamba farmers and outsiders. Improvements local people considered necessary for the shamba system to work included more accountability and transparency in administration and better rules with respect to plot allocation and stewardship. Ninety-seven percent of respondents said they would like to be more involved in management of the forest and 80% that they were willing to pay for the use of a plot. The study concludes that the structural framework laid down by the 2005 Forests Act, which includes provision for the reimplementation of the shamba system under the new plantation establishment and livelihood improvement scheme (PELIS) [It should be noted that whilst the shamba system was re-branded in 2008 under the acronym PELIS, for the sake of simplicity the authors continue to refer to the 'shamba system' and 'shamba farmers' throughout this paper.], is weakened because insufficient power is likely to be devolved to local people, casting them merely as 'forest users' and the shamba system as a 'forest user right'. In so doing the system's potential to both facilitate and embody the participation of local people in forest management is limited and the long-term sustainability of the new system is questionable. Suggested instruments to address this include some degree of sharing of profits from forest timber, performance related guarantees for farmers to gain a new plot and use of joint committees consisting of local people and the forest authorities for long term management of forests.

A new three-locus model for rootstock-induced dwarfing in apple revealed by genetic mapping of root bark percentage

Rootstock-induced dwarfing of apple scions revolutionized global apple production during the twentieth century, leading to the development of modern intensive orchards. A high root bark percentage (the percentage of the whole root area constituted by root cortex) has previously been associated with rootstock induced dwarfing in apple. In this study, the root bark percentage was measured in a full-sib family of ungrafted apple rootstocks and found to be under the control of three loci. Two QTL for root bark percentage were found to co-localise to the same genomic regions on chromosome 5 and chromosome 11 previously identified as controlling dwarfing, Dw1 and Dw2, respectively. A third QTL was identified on chromosome 13 in a region that has not been previously associated with dwarfing. The development of closely linked 3 Sequence-tagged site STS markers improved the resolution of allelic classes thereby allowing the detection of dominance and epistatic interactions between loci, with high root bark percentage only occurring in specific allelic combinations. In addition, we report a significant negative correlation between root bark percentage and stem diameter (an indicator of tree vigour), measured on a clonally propagated grafted subset of the mapping population. The demonstrated link between root bark percentage and rootstock-induced dwarfing of the scion leads us to propose a three-locus model that is able to explain levels of dwarfing from the dwarf ‘M.27’ to the semi-invigorating rootstock ‘M.116’. Moreover, we suggest that the QTL on chromosome 13 (Rb3) might be analogous to a third dwarfing QTL, Dw3 that has not previously been identified.

Double jeopardy in Australia: the illusion of an absolute protection and the prosecution process as punishment

Outline of the nature and scope of the double jeopardy principle as it operates in the pleas in the bar and the court's discretion to prevent an abuse of the process - rationales advanced in favour of doctrine - some anomalies and implications from the claim that the double jeopardy principle is absolute - some suggestions for reform.

Competition policy and prevention of abuses in the TRIPS agreement

The monopoly granted through intellectual property rights can lead to abuses ofsuch monopoly. The TRIPS Agreement recognizes such abuses along with the fact that competition policy can play a significant role in dealing with such abuses. The use of competition policy to deal with the abuse of IP monopolies reguires a discussion ofabuse of the dominant position, definition ot market and substitutability of products and whether the
patenting monopoly automatically puts the right holder in the dominant position. The issue of parallel trade and exhaustion of rights also has anti-competitive implications. The introduction of discriminatory pricing along with any ban on parallel trade would lead to absolute market control, market segregation and market exclusion by the monopolistic industries.

Parent abuse: a review

A recent focus of research and clinical practice has been on the issue of abuse of parents by their children (parent abuse). This paper reviews the literature on this phenomenon. While parent abuse falls under the umbrella of family violence, it appears to be qualitatively different from other forms of intra-family abuse. Research has primarily focused on prevalence rates and the characteristics of perpetrators and victims. While various factors such as gender, age, emotional attachment to parents, race/ethnicity, socioeconomic status, family stress and parenting style and structure have been associated with parent abuse, findings are equivocal. Etiological models are general and untested, and treatment approaches lack empirical support. It is concluded that more rigorous and extensive research is required in order to provide a deeper understanding of this complex issue, and to inform treatment approaches.

Umpire participation: is abuse really the issue?

Umpires (or referees) are essential for the ongoing production of organised sport. It has been widely argued that abuse of umpires by players, coaches, and spectators is ubiquitous and aversive, therefore engendering attrition. Cognitive behavioural theory specifies that attrition and continuation are best understood by identifying the ways that stimuli are interpreted. In this study, 22 umpires of professional and semi-professional Australian Rules football were interviewed to determine what they think of abusive behaviour, and what they find to be rewarding about umpiring. Findings showed that umpires routinely reframe abuse, considering it to be a normal part of their role. Abuse was not deemed to be particularly aversive, and there was no evidence that it contributes to attrition. On the other hand, umpires enjoyed the social world they share with other umpires, and identified social interactions among umpires as a key reason for continuing to umpire. This study highlights the important role that socialisation into the social world of umpiring plays in helping umpires to reframe abuse, and the importance of socialising with other umpires in maintaining their commitment to umpiring. It is suggested that the social rewards of umpiring should be stressed in umpire recruitment, and that the social world of umpiring should be incorporated into umpire training and retention.

Pursuit of the muscular ideal: Physical and psychological consequences and putative risk factors

Developing a lean muscular figure for the purposes of sports and/or appearance has become a central issue for males. Concern has been raised because the desire to develop such a body build may lead to the adoption of numerous health-threatening behaviors. Consequently, this review presents a comprehensive analysis of the physical and psychological consequences that result from the use of steroids (legal and illegal), ephedrine, and deleterious dieting strategies specific to males. Putative risk factors for these behaviors will be identified, and the clinical disorder associated with the extreme abuse of these behaviors, muscle dysmorphia, will be examined.

Aesthetic dimensions of educational administration and leadership

The Aesthetic Dimensions of Educational Administration and Leadership provides an aesthetic critique of educational administration and leadership. It demonstrates the importance of aesthetics on all aspects of the administrative and leadership world: the ways ideas and ideals are created, how their expression is conveyed, the impact they have on interpersonal relationships and the organizational environment that carries and reinforces them, and the moral boundaries or limits that can be established or exceeded.

The book is divided into three sections.
Section I examines various philosophical traditions in aesthetics as they inform administrative life, focussing on major modern traditions arising from Kant, romanticism and Nietzsche, Collingwood, the pragmatic school, and critical theory.
Section II explores four aesthetic sources for administrative critique - architecture, literature, film, and movement - as they serve both to understand the social construction of administration and leadership and provide a critique of values, roles, power and authority.
Section III examines more topical and applied problems of charisma, heroism, and authority in practice, concluding with a discussion of the aesthetic analysis of politics and power within the context of contemporary educational administration and leadership theory.

While presenting a significant departure from conventional studies in the field, the international contributors reflect a continuity of thought on the creation, use and abuse of administrative and leadership authority from the writings of Plato through to contemporary theory. This book should appeal to school administrators and leaders and those aspiring to these roles.

The other side of social exclusion : interrogating the role of the privileged in reproducing inequality

As the chapters in this book demonstrate, social exclusion is a key concept used to understand various forms of inequality in contemporary capitalist societies. I argue in this chapter that while the concept of social exclusion has been important in illustrating the structural dimensions of unequal social relations and examining the costs of those relations for excluded groups, it has done little to address those of us who benefit most from existing social divisions and inequalities. Nor do most of the writings on social exclusion examine how these inequalities are reproduced by and through the daily practices and life-style pursuits of privileged groups.

In this chapter I will interrogate the concept of privilege as the other side of social exclusion and will argue that the lack of critical interrogation of the position of the privileged side of social divisions allows the privileged to reinforce their dominance. I aim to make privilege more visible and consider the extent to which those who are privileged can overcome their own self interest in the maintenance of dominance to enable them to challenge it.

The role of culture in understanding child sexual offending : examining feminist perspectives

Psychological theories on child sexual abuse continue to dominate etiological and rehabilitative approaches to understanding and treating sexually abusive behavior. However, even though psychological researchers are motivated toward development of comprehensive and highly integrated theories, there has been continued neglect of the cultural dimensions of child sexual abuse. Feminist theories of child sexual abuse have been particularly helpful in filling this explanatory gap, as they have persisted in locating sexually abusive behavior within a cultural context. In this paper we review and critique selected feminist theories on child sexual abuse with the aim of establishing their explanatory scope and utility. Overall, we found that feminist perspectives were useful in justifying and establishing social policies aimed at preventing the sexual abuse of children from ever commencing. However, despite this strength, they offer little guidance in the treatment of individual offenders.

Software developer policies : economics and s 46 of the Competition and Consumer Act 2010

This article considers the impact of developer policies that hinder or restrict cross platform application development. We suggest that policies that hinder or restrict cross platform development have the potential to erode competition within the market for smartphones. The article also considers the relevance of dominance measures in software markets, arguing that conventional economic approaches may not be applicable. Furthermore, while most monitoring activities tend to focus primarily on protection of consumers, the article points out that modern electronic/information technology markets are multi-sided and there is a need for monitoring of practices designed to attract and retain the favour of developers. While the article is written in the context and application of the applicable Australian legislation, this being s 46 of the Competition and Consumer Act 2010 (Cth), our findings are equally relevant to other jurisdictions.

Sexual harassment of Australian female general practitioners by patients

In 2010, an Australian survey was undertaken to examine the nature and extent of female general practitioners’ experience of sexual harassment by patients and how they respond to such episodes. Previous research has shown the high prevalence of sexual harassment or abuse of medical practitioners, but little is known about the nature of harassment and responses of individual practitioners.

Post-traumatic stress disorder and quality of life in sexually abused Australian children

The study used publicly available data on post-traumatic stress disorder in a sample of the Australian population with a history of sexual abuse to demonstrate how this evidence can inform economic analyses. The 2007 Australian Mental Health Survey revealed that 8.3% of 993 adolescents experienced childhood sexual abuse, of which 40.2% were diagnosed with post-traumatic stress disorder. Post-traumatic stress disorder diagnosis corresponded to a significant loss of quality of life. Survival analysis was used to estimate the lifetime persistence of post-traumatic stress disorder symptoms. The average time between post-traumatic stress disorder onset and remission was 11.4 years. Results suggest that successful treatment of post-traumatic stress disorder will save 2.05 quality adjusted life years per child or adolescent with post-traumatic stress disorder.
