Pilot study comparing physical and psychological responses in medical qigong and walking

Identifying alternative exercise modalities in an effort to stimulate and promote participation in physical activity, especially among older adults, is a critical health consideration. The purpose of this study was to compare physiological and psychological responses to medical qigong with self-paced brisk walking. Older women (55-79 years) performed 22 min of either qigong or walking on two separate days. During exercise performance, heart rate and ratings of perceived exertion were assessed. Psychological affect, blood pressure, and pulse rate were assessed before and after the exercise bouts. Heart-rate data indicated that both forms of exercise were at a moderate level of intensity. In addition, similar values were found for the physiological and psychological variables as a function of the two forms of exercise. Therefore, it was concluded that this form of medical qigong can be considered a moderate-intensity physical activity that should have both physiological and psychological benefits for older women.     

Are Private Schools Better Than Public Schools? Appraisal for Ireland by Methods for Observational Studies

In observational studies the assignment of units to treatments is not under control. Consequently, the estimation and comparison of treatment effects based on the empirical distribution of the responses can be biased since the units exposed to the various treatments could differ in important unknown pretreatment characteristics, which are related to the response. An important example studied in this article is the question of whether private schools offer better quality of education than public schools. In order to address this question we use data collected in the year 2000 by OECD for the Programme for International Student Assessment (PISA). Focusing for illustration on scores in mathematics of 15-years old pupils in Ireland, we find that the raw average score of pupils in private schools is higher than of pupils in public schools. However, application of a newly proposed method for observational studies suggests that the less able pupils tend to enroll in public schools, such that their lower scores is not necessarily an indication of bad quality of the public schools. Indeed, when comparing the average score in the two types of schools after adjusting for the enrollment effects, we find quite surprisingly that public schools perform better on average. This outcome is supported by the methods of instrumental variables and latent variables, commonly used by econometricians for analyzing and evaluating social programs.     

Impaired Probability Estimation and Decision-Making in Pathological Gambling Poker Players

Poker has gained tremendous popularity in recent years, increasing the risk for some individuals to develop pathological gambling. Here, we investigated cognitive biases in a computerized two-player poker task against a fictive opponent, among 12 pathological gambling poker players (PGP), 10 experienced poker players (ExP), and 11 inexperienced poker players (InP). Players were compared on probability estimation and decision-making with the hypothesis that ExP would have significantly lower cognitive biases than PGP and InP, and that the groups could be differentiated based on their cognitive bias styles. The results showed that ExP had a significantly lower average error margin in probability estimation than PGP and InP, and that PGP played hands with lower winning probability than ExP. Binomial logistic regression showed perfect differentiation (100%) between ExP and PGP, and 90.5% classification accuracy between ExP and InP. Multinomial logistic regression showed an overall classification accuracy of 23 out of 33 (69.7%) between the three groups. The classification accuracy of ExP was higher than that of PGP and InP due to the similarities in probability estimation and decision-making between PGP and InP. These impairments in probability estimation and decision-making of PGP may have implications for assessment and treatment of cognitive biases in pathological gambling poker players.     

Conceptual design pattern for ergonomic workplaces

In this paper, we analyzed two laboratories of liquid chromatography (LC), separation technique of mixtures and identification of its components, in order to identify projectual gaps relating to the environment and the working station. The methodology used was the ergonomic analysis with interactional and participatory techniques applied during the activity performance. This work incorporated and adapted the concept developed by Alexander (1979)--pattern languages--passing from architectural projects to workstations project and physical arrangement of the work environment. The adaptation of the concept resulted in a list of recommendations, requirements and concepts that have brought design solutions for the problematic aspects observed in the ergonomic analysis. The employed methodology, strongly supported in ergonomics principles, and in interactional and participatory techniques, contributed to achieve our gold that is what we now call Conceptual Standards. The patterns go beyond of a usual model of book a of ergonomics specification, once incorporating the viewpoint of the end user, it is also a set of best project practices and of project management in conception ergonomics.     

Cautionary Notes on Navigating the Neurocognitive Turn

The approach sociologists should take toward the biological sciences, particularly in light of the neurocognitive turn that is taking place in many other disciplines, is not as straightforward as some have suggested. Advocates of bridging neurocognitive and sociological frameworks have argued that we should learn and utilize neurocognitive science in order to refresh sociological concepts, as well as to contribute positively to the development of bio/psycho/social knowledge. However, I argue that the onto‐epistemological question of how we should approach neuroscientific knowledge, which has yet to be resolved, should be foregrounded rather than forgotten in these efforts. Without a willingness to criticize as well as learn from neurocognitive science, and wade into its internal debates, sociologists risk reifying neurocognitive knowledge and diminishing awareness and appreciation of its complexities and contradictions.     

Challenging Dominant Discourses: Peer Work as Social Justice Work

ABSTRACT

People with mental illnesses are overrepresented in the criminal justice system, and discourses concerning the medical model, criminalization, and criminality dominate the intervention landscape for this population. Using a critical postmodern lens, 45 in-depth interviews with peer specialists who had incarceration histories were analyzed to understand how they approach their work. Peer specialists with incarceration histories constructed new identities through their training and peer work by valuing experiential knowledge. Even in the face of power differentials, they challenged dominant discourses directly and indirectly and advocated for various forms of help for the people with whom they worked.     

The Availability of Supervision in Routine Mental Health Care

Clinical supervision is an embedded resource for practice quality in community mental health organizations. Supervision has been found to increase provider competence and decrease stress. In addition, supervision has been associated with service user outcomes including decreased depressive symptoms. However, little is known about the availability and nature of supervision in real world settings. The primary aims of this study were to identify available supervision and the extent to which contextual factors are related to that availability. The data source for this study was a multi-state and multi-site (N?=?14) NIMH-funded trial survey of providers (N?=?273). Supervision was measured by hours per week (quantity) and by utilization of best practice activities (content). Univariate, Chi square, independent samples t-tests, and ANOVA analyses were used to assess supervision content and quantity and to examine subgroup differences. Participants reported an average of 2.17 h of supervision per week and 28.6% of participants endorsed best practice content. Supervision quantity varied significantly across sites (p?<?0.05) and program type (p?<?0.05) while content did not. Individual role within the organization had a significant relationship with reported supervision content (p?<?0.001). In these settings, staff in organizations are exercising discretion in how to utilize supervision within the available time. Supervision time also varied by program type, increasing with the intensity of services. Findings demonstrate that reports of availability vary according to position within the organization and the intensity of services within a given program type. Implications for workforce development, access to quality services, and implementation of evidence-based practices are discussed.
