A Systematic Review of Theoretical Foundations for Pedagogical Strategies to Promote Positive Behavior

This study analysed the theoretical foundations utilised by past empirical research in order to understand the pedagogical strategies used in schools for promoting positive behaviour. The analyses also include how pedagogical theories underpinned past research on positive behaviour enhancement. Samples for this study were academic papers obtained from four main databases: the Australian Education Index, British Education Index, ERIC (Educational Research Information Centre) and Scopus. By using a systematic review technique, a total number of 143 papers were found to be relevant for further analysis. Results revealed that four theoretical models dominate the studies examined, namely Applied Behavioural Analysis, Social Capital theory, Culturally Responsive Classroom Management, and Ecological Systems theory. This study recommends understanding of those theories is important in designing modules for positive behaviour enhancement in schools

Reefs at Risk: A Map-Based Indicator of Threats to the Worlds Coral Reefs

This report presents the first-ever detailed, map-based assessment of potential threats to coral reef ecosystems around the world. "Reefs at Risk" draws on 14 data sets (including maps of land cover, ports, settle-ments, and shipping lanes), information on 800 sites known to be degraded by people, and scientific expertise to model areas where reef degradation is predicted to occur, given existing human pressures on these areas. Results are an indicator of potential threat (risk), not a measure of actual condition. In some places, particularly where good management is practiced, reefs may be at risk but remain relatively healthy. In others, this indicator underestimates the degree to which reefs are threatened and degraded.Our results indicate that:Fifty-eight percent of the world's reefs are poten-tially threatened by human activity -- ranging from coastal development and destructive fishing practices to overexploitation of resources, marine pollution, and runoff from inland deforestation and farming.Coral reefs of Asia (Southeastern); the most species-rich on earth, are the most threatened of any region. More than 80 percent are at risk (undermedium and high potential threat), and over half are at high risk, primarily from coastal development and fishing-related pressures.Overexploitation and coastal development pose the greatest potential threat of the four risk categories considered in this study. Each, individually, affects a third of all reefs.The Pacific, which houses more reef area than any other region, is also the least threatened. About 60 percent of reefs here are at low risk.Outside of the Pacific, 70 percent of all reefs are at risk.At least 11 percent of the world's coral reefs contain high levels of reef fish biodiversity and are under high threat from human activities. These "hot spot" areas include almost all Philippine reefs, and coral communities off the coasts of Asia, the Comoros, and the Lesser Antilles in the Caribbean.Almost half a billion people -- 8 percent of the total global population -- live within 100 kilometers of a coral reef.Globally, more than 400 marine parks, sanctuaries, and reserves (marine protected areas) contain coral reefs. Most of these sites are very small -- more than 150 are under one square kilometer in size. At least 40 countries lack any marine protected areas for conserving their coral reef systems

The Pro-Apoptotic Proteins, Bid and Bax, Cause a Limited Permeabilization of the Mitochondrial Outer Membrane That Is Enhanced by Cytosol

During apoptosis, an important pathway leading to caspase activation involves the release of cytochrome c from the intermembrane space of mitochondria. Using a cell-free system based on Xenopus egg extracts, we examined changes in the outer mitochondrial membrane accompanying cytochrome c efflux. The pro-apoptotic proteins, Bid and Bax, as well as factors present in Xenopus egg cytosol, each induced cytochrome c release when incubated with isolated mitochondria. These factors caused a permeabilization of the outer membrane that allowed the corelease of multiple intermembrane space proteins: cytochrome c, adenylate kinase and sulfite oxidase. The efflux process is thus nonspecific. None of the cytochrome c-releasing factors caused detectable mitochondrial swelling, arguing that matrix swelling is not required for outer membrane permeability in this system. Bid and Bax caused complete release of cytochrome c but only a limited permeabilization of the outer membrane, as measured by the accessibility of inner membrane-associated respiratory complexes III and IV to exogenously added cytochrome c. However, outer membrane permeability was strikingly increased by a macromolecular cytosolic factor, termed PEF (permeability enhancing factor). We hypothesize that PEF activity could help determine whether cells can recover from mitochondrial cytochrome c release

A realist evaluation of mechanisms and contexts for facilitating the implementation of supported self-management in community stroke care (the IMPETUS study)

The past decade has seen a growing recognition of the role of supported self-management in the provision of long-term care and support for stroke survivors in primary and community care. However, its implementation and delivery across different contexts and models of community stroke care is inconsistent and patchy. This realist evaluation explored how and in which circumstances supported self-management is enacted and delivered within community stroke rehabilitation. Specifically, the study aimed to identify and explore contexts, mechanisms, and outcomes related to the delivery of collaborative supported self-management. It comprised a realist synthesis, Q-methodology study, and realist-informed interviews and focus groups with stroke survivors (n = 20), community-based stroke practitioners (n = 20), and community service delivery managers/clinical leads (n = 8) in stroke. The findings revealed that delivering supported self-management effectively and consistently in community stroke rehabilitation starts with embedding the ethos of collaborative supported self-management across staff, teams, and the organisation and involves collaborative relationships with stroke survivors that aim to build trust, confidence, and resilience. The findings identified specific mechanisms and facilitatory and inhibitory contexts that influence how well this is enacted and achieved in practice. A realist approach in this study is novel and has helped to generate new insights and perspectives how and when supported self-management approaches work in community stroke rehabilitation. The findings expand on and complement existing research on the efficacy of supported self-management in stroke and are of clinical importance for informing how collaborative, relational supported self-management approaches can be implemented, personalised, and tailored to people’s needs and evaluated within current healthcare systems

Redesign and initial validation of an instrument to assess the motivational qualities of music in exercise: The Brunel Music Rating Inventory-2

In the present study, a measure to assess the motivational qualities of music in exercise was redesigned, extending previous research efforts (Karageorghis et al., 1999). The original measure, the Brunel Music Rating Inventory (BMRI), had shown limitations in its factor structure and its applicability to non-experts in music selection. Redesign of the BMRI used in-depth interviews with eight participants (mean age 31.9 years, s¼8.9 years) to establish the initial item pool, which was examined using a series of confirmatory factor analyses. A single-factor model provided a good fit across three musical selections with different motivational qualities (comparative fit index, CFI: 0.95 – 0.98; standardized root mean residual, SRMR: 0.03 – 0.05). The single-factor model also demonstrated acceptable fit across two independent samples and both sexes using one piece of music (CFI: 0.86 – 1.00; SRMR: 0.04 – 0.07). The BMRI was designed for experts in selecting music for exercise (e.g. dance aerobic instructors), whereas the BMRI-2 can be used both by exercise instructors and participants. The psychometric properties of the BMRI-2 are stronger than those of the BMRI and it is easier to use. The BMRI-2 provides a valid and internally consistent tool by which music can be selected to accompany a bout of exercise or a training session. Furthermore, the BMRI-2 enables researchers to standardize music in experimental protocols involving exercise-related tasks

Rates of Tuberculosis Infection in Healthcare Workers Providing Services to HIV-Infected Populations

Objective: To assess the prevalence of tuberculosis (TB) or a positive skin test in healthcare workers (HCWs) providing services to human immunodeficiency virus (HIV)-infected individuals and to determine prospectively the incidence of new infections in this population. Design: This prospective cohort study enrolled 1,014 HCWs working with HIV-infected populations from 10 metropolitan areas. Purified protein derivative (PPD) tuberculin skin tests were placed at baseline and every 6 months afterwards on those without a history of TB or a positive PPD. Demographic, occupational, and TB exposure data also were collected. Setting: Outpatient clinics, hospitals, private practice offices, and drug treatment programs providing HIV-related healthcare and research programs. Participants: A voluntary sample of staff and volunteers from 16 Community Programs for Clinical Research on AIDS units. Results: Factors related to prior TB or a positive skin test at baseline included being foreign-born, increased length of time in health care, living in New York City, or previous bacille Calmette-Guerín vaccination. The rate of PPD conversion was 1.8 per 100 person years of follow-up. No independent relation was found between the amount or type of contact with HIV-infected populations and the risk of TB infection. Conclusion: These data provide some reassurance that caring for HIV-infected patients is not related to an increased rate ofTB infection among HCWs in these settings

ReseArch with Patient and Public invOlvement: a RealisT evaluation - the RAPPORT study

Background Patient and public involvement (PPI) is a prerequisite for many funding bodies and NHS research ethics approval. PPI in research is defined as research carried out with or by the public rather than to, about or for them. While the benefits of PPI have been widely discussed, there is a lack of evidence on the impact and outcomes of PPI in research. Objectives To determine the types of PPI in funded research, describe key processes, analyse the contextual and temporal dynamics of PPI and explore the experience of PPI in research for all those involved. Mechanisms contributing to the routine incorporation of PPI in the research process were assessed, the impact of PPI on research processes and outcomes evaluated, and barriers and enablers to effective PPI identified. Design A three-staged realist evaluation drawing on Normalisation Process Theory to understand how far PPI was embedded within health-care research in six areas: diabetes mellitus, arthritis, cystic fibrosis, dementia, public health and learning disabilities. The first two stages comprised a scoping exercise and online survey to chief investigators to assess current PPI activity. The third stage consisted of case studies tracked over 18 months through interviews and document analysis. The research was conducted in four regions of England. Participants Non-commercial studies currently running or completed within the previous 2 years eligible for adoption on the UK Clinical Research Network portfolio. A total of 129 case study participants included researchers and PPI representatives from 22 research studies, and representatives from funding bodies and PPI networks

Nature-Based Interventions for Improving Health and Wellbeing : The Purpose, the People and the Outcomes

Engagement with nature is an important part of many people's lives, and the health and wellbeing benefits of nature-based activities are becoming increasingly recognised across disciplines from city planning to medicine. Despite this, urbanisation, challenges of modern life and environmental degradation are leading to a reduction in both the quantity and the quality of nature experiences. Nature-based health interventions (NBIs) can facilitate behavioural change through a somewhat structured promotion of nature-based experiences and, in doing so, promote improved physical, mental and social health and wellbeing. We conducted a Delphi expert elicitation process with 19 experts from seven countries (all named authors on this paper) to identify the different forms that such interventions take, the potential health outcomes and the target beneficiaries. In total, 27 NBIs were identified, aiming to prevent illness, promote wellbeing and treat specific physical, mental or social health and wellbeing conditions. These interventions were broadly categorized into those that change the environment in which people live, work, learn, recreate or heal (for example, the provision of gardens in hospitals or parks in cities) and those that change behaviour (for example, engaging people through organized programmes or other activities). We also noted the range of factors (such as socioeconomic variation) that will inevitably influence the extent to which these interventions succeed. We conclude with a call for research to identify the drivers influencing the effectiveness of NBIs in enhancing health and wellbeing.Peer reviewe

Adolescent male hazardous drinking and participation in organised activities: Involvement in team sports is associated with less hazardous drinking in young offenders

Aims: The purpose of this research was to test and compare associations between participation in organised activities and indicators of hazardous drinking between young offenders and young non-offenders. Methods: Two groups of 13–18 year-old males were recruited in Cardiff, UK: 93 young offenders and 53 non-offenders from secondary schools matched on estimated IQ, sex and socioeconomic status. Indicators of hazardous drinking were measured using the Fast Alcohol Screening Test (FAST). Organised activity participation and externalising behaviour was measured by the Youth Self Report. The Wechsler Abbreviated Scale of Intelligence was also administered. Results: Young offenders participated in fewer organised activities and had higher FAST scores than non-offenders. Young offenders and non-offenders significantly differed on mean FAST scores if they participated in no organised activities but not if they participated in at least one team sport. Externalising behaviour problems were unrelated to participation in organised activities. Conclusions: Although young offenders were less likely to have participated in organised activities, for them, participation in a team sport was associated with less hazardous drinking. Vulnerable youths who might benefit most from sporting activities actually access them the least. Future research should identify the different barriers to participation that they face
