Beliefs, values, and action : the judgment model of cognitive distortions in sexual offenders

In this paper, we present the Judgment Model of Cognitive Distortions (JMCD), a new model of cognitive distortions that spans multiple levels of analysis and contains different types of judgments. This model proposes that cognitive distortions tend to cluster together in what we have termed Thematic Networks (TN): judgments about beliefs, values, and actions. We argue that the three sets of judgments cover all types of cognitive distortions apparent in sexual offenders including those revolving around content (i.e., asserting characteristics to people, the offender, the world) and cognitive operations (i.e., denial, minimization, rationalizations). Following a description of the JMCD, we demonstrate how it can account for the cognitive schemata identified in sexual offenders by researchers and clinicians. The paper concludes with a brief discussion of the clinical and research implications of the JMCD.

Coproduction in practice : participatory action research to develop a model of community aged care

Coproduction has become synonymous with innovative approaches to public service delivery in European Union countries as well as in Australia. Coproduction has the potential to bring together individuals, communities, and organisations in a process to collaboratively develop new models and services which improve public services. Yet, Australian policy makers and practitioners who would like to deploy coproduction within the context of older adult social care can only draw on a handful of papers and reports that could guide implementation. This paper fills this gap by reporting on the implementation of a multi-stakeholder coproduction approach to the development of a consumer directed care model for older people with complex health issues. The paper describes and critically highlights methodological challenges encountered during the 12 month-long participatory action research phase of a larger project involving older people with complex care needs, their carers, and government and non-government stakeholders. The paper outlines key considerations regarding (1) the involvement of older people with complex needs, (2) collaboration with industry partners, (3) engagement of government representatives, and (4) reflects on implementing participatory research projects within a context of outsourcing and interlinked supply chains. While not all challenges encountered could be resolved, the coproduction approach was successful in bringing together a wide range of stakeholders with competing agendas in an iterative process geared to resolve a plethora of concerns raised by older people, carers and services providers. This paper provides an example for others seeking to use coproduction and participatory methods to provide person-centred care services for older people.

From personal reflection to social positioning: the development of a transformational model of a professional education in midwifery

A transformational model of professional identity formation, anchored and globalized in workplace conversations, is advanced. Whilst the need to theorize the aims and methods of clinical education has been served by the techno-rational platform of 'reflective practice', this platform does not provide an adequate psychological tool to explore the dynamics of social episodes in professional learning and this led us to positioning theory. Positioning theory is one such appropriate tool in which individuals metaphorically locate themselves within discursive action in everyday conversations to do with personal positioning, institutional practices and societal rhetoric. This paper develops the case for researching social episodes in clinical education through professional conversations where midwifery students, in practice settings, are encouraged to account for their moment-by-moment interactions with their preceptors/midwives and university mentors. It is our belief that the reflection elaborated by positioning theory should be considered as the new epistemology for professional education where professional conversations are key to transformative learning processes for persons and institutions.

Arsenic, mode of action at biologically plausible low doses : what are the implications for low dose cancer risk?

Arsenic is an established human carcinogen. However, there has been much controversy about the shape of the arsenic response curve, particularly at low doses. This controversy has been exacerbated by the fact that the  mechanism(s) of arsenic carcinogenesis are still unclear and because there are few satisfactory animal models for arsenic-induced carcinogenesis. Recent epidemiological studies have shown that the relative risk for cancer among populations exposed to ≤60 ppb As in their drinking water is often lower than the risk for the unexposed control population. We have found that treatment of human keratinocyte and fibroblast cells with 0.1 to 1 μM arsenite (As^III) also produces a low dose protective effect against oxidative stress and DNA damage. This response includes increased transcription, protein levels and enzyme activity of several base excision repair genes, including DNA polymerase β and DNA ligase I. At higher concentrations (> 10 μM), As induces down-regulation of DNA repair, oxidative DNA damage and apoptosis. This low dose adaptive (protective) response by a toxic agent is known as hormesis and is characteristic of many agents that induce oxidative stress. A mechanistic model for arsenic carcinogenesis based on these data would predict that the low dose risk for carcinogenesis should be sub-linear. The threshold dose where toxicity outweighs protection is hard to predict based on in vitro dose response data, but might be estimated if one could determine the form (metabolite) and concentration of arsenic responsible for changes in gene regulation in the target tissues.

A new model of workbased learning in the VET sector

This report provides a revised model of workbased learning for the vocational education and training (VET) sector in Australia, in response to emerging needs. The study provides a brief review of the theoretical foundations of the contemporary discussions surrounding workbased learning, drawn from literature on adult education and learning organisations. Literature on adult learning and learning organisations in the 1990's explored new dimensions of these topics and this new theorising enriched the concept of workbased learning. This examination of the literature enables the development of a model of an integrated approach to workbased learning. The model integrates compatible ideas from adult learning, learning organisations and action learning/research and facilitates new ways of thinking about workbased learning as a staff development model. This model confirms that workbased learning is an appropriate and relevant approach to staff development in contemporary times.

Role of dopamine D3 and serotonin 5-HT1A receptors in l-DOPA-induced dyskinesias and effects of sarizotan in the 6-hydroxydopamine-lesioned rat model of Parkinson's disease

Sarizotan, a 5-HT1A agonist with additional affinity for D3 and D4 receptors, has been demonstrated to have anti-dyskinetic effects. The mechanism by which these effects occur is not clear. Using unilateral 6-hydroxydopamine-lesioned rats that received chronic intraperitoneal (ip) administration of L-3,4-dihydroxyphenylalanine (L-DOPA) we investigated the involvement of D3 and 5-HT1A receptors in the effects of sarizotan on contraversive circling and abnormal involuntary movements (AIMs). Before sensitization by chronic L-DOPA treatment (12.5 with 3.25 mg/kg benserazide ip, twice daily for 21 days), no effect of the selective D3 agonist, PD128907 (1 or 3 mg/kg ip), or the selectiveD3 antagonist,GR103691 (0.5 or 1.5 mg/kg ip), was observed. Treatment with sarizotan (1 or 5 mg/kg ip) dosedependently inhibited the L-DOPA-induced contraversive turning and AIMs. In co-treatment with the 5-HT1A antagonist, WAY100635 (1 mg/kg ip), sarizotan failed to affect this behaviour, confirming the prominent 5-HT1A receptor-mediated mechanism of action. In the presence of PD128907 (3 mg/kg ip), the effects of sarizotan on contraversive turning, locomotive dyskinesia and axial dystonia, but not on orolingual and forelimb dyskinesia, were blocked. On its own, PD128907 had no effect on the behavioural effects of L-DOPA except that it tended to reduce orolingual and forelimb dyskinesia. GR103691 had no effect on its own or in combination with sarizotan. These data identify an involvement of D3 receptors in the action of sarizotan on some, but not all L-DOPA-induced motor side effects. This selective involvement is in contrast to the more general involvement of 5-HT1A receptors in the anti-dyskinetic effects of sarizotan.

Analysis of the stages of change model of drug and alcohol treatment readiness among prisoners

A classification and regression tree (CART) analysis was applied to data for 237 male participants (M = 31.93 years, SD = 7.64) in a prison-based substance abuse treatment program to study the integrity of the Stages of Change model of treatment readiness. Using the Stages of Change Questionnaire (STOCQ), participants were assigned to Contemplation (102), Action (118), or Maintenance (17) groups. A CART analysis then examined differences in the overall group profiles on the basis of scores on the Psychological Inventory of Criminal Thinking, the Situational Confidence Questionnaire, and the Carlson Psychological Survey. The assumption of discrete stages of change was not supported. Alternative models are suggested: one based on states of change and one on personality characteristics. A focus on equal attention to both cognitive and behavioral aspects of substance abuse treatment readiness is suggested.

The M4 muscarinic antagonist MT-3 inhibits myopia in chick: evidence for site of action

It is well established that the broad-band muscarinic antagonist, atropine is effective at inhibiting the progression of myopia and does so by preventing the elongation of the vitreous chamber of the eye. However, uncertainty remains as to whether this effect occurs through a receptoral mechanism and, if so, which muscarinic receptor subtype mediates this effect. Previous work, in avian and mammalian models of myopia, implicates the M1 and M4 receptors as potential targets. The current study used physiologically relevant concentrations of highly selective muscarinic antagonists (MT-3 and MT-7) to further characterise the role of the M4 receptor in the control of myopia in the chick model of refractive development.

Doing the right thing at the right time: Assessing responses to patient deterioration in electronic simulation scenarios using course-of-action analysis

International studies indicate that the recognition and management of deteriorating patients in hospitals are poor and that patient assessment is often inadequate. Face-to-face simulation programs have been shown to have an impact on educational and clinical outcomes; however, little is known about performance in contemporary healthcare e-simulation approaches. Using data from an open-access Web-based patient deterioration program (FIRSTACTWeb), the performance of 367 Australian nursing students in identification of treatment priorities and clinical actions was analyzed using a military model of Course of Action Simulation Analysis. Participants' performance in the whole program demonstrated a significant improvement in knowledge and skills (P ≤ .001) with high levels of participant satisfaction. Course of Action Simulation Analysis modeling identified three key participant groupings within which only 18% took the "best course of action" (the right actions and timing), with most (70%) completing the right actions but in the wrong order. The remaining 12% produced incomplete assessments and actions in an incorrect sequence. Contemporary approaches such as e-simulation do enhance educational outcomes. Measurement of performance when combined with Course of Action Simulation Analysis becomes a useful tool in the description of outcomes, an understanding of decision making, and the prediction of future events.

Finding line of action of the force exerted on erect spine based on lateral bending test in personalization of scoliotic spine models

In multi-body models of scoliotic spine, personalization of mechanical properties of joints significantly improves reconstruction of the spine shape. In personalization methods based on lateral bending test, simulation of bending positions is an essential step. To simulate, a force is exerted on the spine model in the erect position. The line of action of the force affects the moment of the force about the joints and thus, if not correctly identified, causes over/underestimation of mechanical properties. Therefore, we aimed to identify the line of action, which has got little attention in previous studies. An in-depth analysis was performed on the scoliotic spine movement from the erect to four spine positions in the frontal plane by using pre-operative X-rays of 18 adolescent idiopathic scoliosis (AIS) patients. To study the movement, the spine curvature was considered as a 2D chain of micro-scale motion segments (MMSs) comprising rigid links and 1-degree-of-freedom (DOF) rotary joints. It was found that two MMSs representing the inflection points of the erect spine had almost no rotation (0.0028° ± 0.0021°) in the movement. The small rotation can be justified by weak moment of the force about these MMSs due to very small moment arm. Therefore, in the frontal plane, the line of action of the force to simulate the left/right bending position was defined as the line that passes through these MMSs in the left/right bending position. Through personalization of a 3D spine model for our patients, we demonstrated that our line of action could result in good estimates of the spine shape in the bending positions and other positions not included in the personalization, supporting our proposed line of action.
