Classification of biomedical signals for differential diagnosis of Raynaud's phenomenon

This paper discusses a supervised classification approach for the differential diagnosis of Raynaud's phenomenon (RP). The classification of data from healthy subjects and from patients suffering for primary and secondary RP is obtained by means of a set of classifiers derived within the framework of linear discriminant analysis. A set of functional variables and shape measures extracted from rewarming/reperfusion curves are proposed as discriminant features. Since the prediction of group membership is based on a large number of these features, the high dimension/small sample size problem is considered to overcome the singularity problem of the within-group covariance matrix. Results on a data set of 72 subjects demonstrate that a satisfactory classification of the subjects can be achieved through the proposed methodology.     

‘Coming Out Tales’: Adult Sons and Daughters' Feelings About Their Gay Father's Sexual Identity

Coming out to their children is a dilemma that concerns many gay, bisexual, and lesbian parents with children from previous heterosexual relationships. How children found out about having a father who identified himself as gay, and their feelings about their father's sexual identity, were explored through qualitative analysis of semi‐structured interviews with 36 sons and daughters (aged 19 to 36 years) whose gay fathers participated in the Gay & Bisexual Parenting Survey (Barrett and Tasker, 2001). Interpretative Phenomenological Analysis revealed that awareness of their father's sexual identity was often left unspoken for various reasons, and that acceptance came about through gradual understanding as well as direct discussion. Interview data indicated the complexity of the relationship between the young adult's personal acceptance of their father's gay identity and their consideration of social context when deciding how open to be to others about their father's sexual identity. This research has varied implications for therapeutic work with gay and bisexual fathers coming out to their children from previous heterosexual relationships.     

Determining anthropometric variables as a tool in the preparation of furniture and designs of interior spaces: the case of children 6 to 11 years old of Vicosa, State of Minas Gerais, Brazil

The adequacy of facilities and the individual securities in their different age groups is importance to ensure greater functionality to them, allowing full development of daily activities. For this to occur more efficiently it is necessary the use of ergonomics which can ensure more comfort and safety for end users of products and spaces. The present study aimed to measure body dimensions of a representative sample of children aged 6 to 11 years old, children of graduate and pos graduate students, faculty and staff of the Federal University of Vicosa and also residents of the city of Vicosa, State of Minas Gerais, Brazil, coming from different municipalities of State of Minas Gerais, to organize a database that will provide the furniture industry, anthropometric variables more appropriate to design products for both the leisure activities, and for the school sector. To realize this research we used the methodology proposed by the authors Panero and Zelnik, based on samples distributed in six age groups, and providing a measurement of 10 variables. By applying the methodology to the field was possible to compare the observed data, with the tables of the aforementioned authors. The main results revealed a significant variation of the 10 variables analyzed, and it is believed that this variation could lead to possible flaws in the designs of products that use the data from these authors. The completion of the study provided data on Vicosa considered more appropriate for the design of products and environments for the population of the study, considering age and region, of Brazil (State of Minas Gerais) and it is believed that the future may expand to the Brazilian population, with the progress of study of this nature.     

Structuring of manual of orientations and technical information for laundries of industries of animal products origin

This study looked for to lift information regarding laundries inserted in industries of animal products origin, to understand the activities developed in the section and to structure a Manual of Planning and Technical Information for laundries to industries of animal products origin, with the intention of subsidizing the planning, structuring and control of this work place, because norms or regulations that supervise don't exist or aid their managers and workers as for the operation of this work place.     

Evaluation and control of ergonomics actions in federal public service: the case of FIOCRUZ-RJ

This article presents information about the development of the dissertation. Deals with the production of ergonomic diagnosis in the environments and work processes of an important center of research and development in Public Health, FIOCRUZ. Critically evaluates the performance of a team promoting and facilitating the process of implementing ergonomic changes suggested. Through analysis of documents and statements by some managers and representatives of Human Resources was possible to identify the factors that facilitate and hinder the implementation process, linking them to the organization of the institution and conduct of the agents involved. Finally, it makes a reflection on practice, results and developments involved in the processes of change initiated by the ergonomic actions, proposing its replication along with other institutes of the Civilian Personnel of Federal Public Administration.     

Process of precocious functional aging in workers of laundries

The World Health Organization (WHO), as well as researchers of the whole world, it has been demonstrating concern with the subject of the aging related to the work and it recognizes that modifications in the several systems of the human body take to the gradual decrease in the effectiveness of each one of them, because the aging caused by the work advances apprenticeships of the cycle of the man's life, not respecting the natural state of that process. In this sense, it was aimed at with this research to investigate the relative aspects to the capacity for the work and to the workers' with responsibility to realize the work in the laundries service, verifying if they present signs of precocious functional aging.     

Cortisol on Sunday as indicator of recovery from work: Prediction by observer ratings of job demands and control

Several considerations guided the research reported in this paper. First, recovery is pivotal for preventing stressful experiences from inducing long-term consequences. Second, cortisol levels under relaxed conditions constitute a good baseline measure. Third, there are many calls to avoid common method problems. Therefore, the Job Demands–Control (JDS) model, one of the most prominent models in occupational stress, should be tested by a combination of observation, self-report, and physiological data in terms of predicting recovery-related variables. In a sample of 53 Swiss employees, we assessed the JDS variables, demands and control, by systematic observation, fatigue at the end of work as an indicator of short-term recovery by questionnaire, and delayed recovery by baseline levels of cortisol on a Sunday under relaxing conditions. In line with expectations, regression analyses showed an impact of job demands and control on Sunday cortisol levels, and this effect was fully mediated by after work fatigue. Contrary to expectations, there was no significant interaction between job demands and control. Demonstrating that job demands and control predict after-work fatigue as well as a delayed physiological marker of recovery, these findings suggest that high after-work fatigue may entail costs to the individual’s physiological systems.     

Researching the Social Impact of Arts and Disability: Applying a New Empirical Tool and Method

This paper has a twofold focus: to establish a method of assessing the potential social impact of arts and disability projects and to apply this method to ten such projects. It does so by using a newly developed ‘ripple’ model that conceptualises social impact in terms of the development of active citizenship on the part of all participants over time. The model identifies ten factors (programme activity, welcoming, belonging, programme social values, individual social values, programme networks, individual networks, skills and creativity, programme wider social impact, and individual wider social impact) which evolve through four progressive stages. The original model is empirically adapted for application to arts and disability projects. Qualitative data were collected in the form of interviews, surveys and media reports across ten case studies, each representing a major arts and disability project offering a professional outcome for an external audience. The qualitative data were coded to provide a simple scoring tool for each case. The results support the application of the model in this context. Furthermore, findings indicate three critical conditions which enable projects to generate considerable positive social impact beyond the individual; ensemble in nature; project embeddedness; and networks and partnerships.     

The experiences of adolescents and young adults residing with their families in emergency shelters in Canada

Emergency homeless shelters can be stressful environments for families. They can be associated with emotional distress and feelings of restriction for parents, and with behavioural, social, and developmental challenges for children. However, little is known about the experiences of accompanied youth residing in shelter with their families, as the literature about this age group's experiences of homelessness has mainly focused on unaccompanied youth. Findings from the current study are drawn from qualitative interviews with 16 adolescents and young adults (aged 16–21) who were homeless and living with their families in family homeless shelters in Ottawa, Ontario, Canada. Youth described family homeless shelters as stressful environments but also found that the shelters provided support to them and their families. Youth discussed the various strategies they used to cope in facing the challenges of shelter life. These findings add to our understanding of youth who are homeless and highlight the ways in which they adapt to the challenges of living in a family homeless shelter with their families. Recommendations are included for ways that shelter staff and policymakers can enact operational and systemic changes that could potentially improve the experiences of such youth and their families.     

Behaviour change strategies for problem gambling: an analysis of online posts

Reducing or quitting problematic gambling often requires implementing a variety of behaviour change strategies, but there is limited evidence regarding the breadth of specific strategies that gamblers use to control or limit gambling behaviours. This study aimed to identify the range of change strategies reported by gamblers in a naturalistic setting (i.e. two online forums for problem gambling). A total of 2937 change strategies were extracted from online posts (N = 1370). Content analysis identified 27 discrete change strategies that were pre-decisional (i.e. barriers – behavioural and psychological, decisional balance, realization – behaviour and cognitions, set reasons to change, seek knowledge and information, self-assessment), pre-actional (i.e. action planning, commitment, goal setting), actional (i.e. alternative activity, behavioural substitution, avoidance – abstinence, environment and financial, consumption control, maintain readiness, reinforcement, urge management, cognitive restructuring, seek inspiration, self-monitoring and spiritual) and multi-phased (i.e. external support, social support and well-being). This study suggests the breadth and depth of change strategies are far more complex than previously reported. Future research with a broader population needs to determine which change strategies are most effective for those experiencing different levels of gambling problems.
