This paper contributes to the growing body of work on precarious labor, immigration, and social gerontology by examining the racialization of precarious employment across the life course. In particular, the authors examine the impact of precarious employment and discrimination among racialized older immigrants in Canada. Racialized older immigrants are more likely to be disadvantaged by the effects of lifelong intersections of economic and social discrimination rooted in racialization, gender, ageism, and socio-economic status.

The Exercise Benefits/Barriers Scale (EBBS) research instrument has been extensively used to investigate the perceived benefits and barriers of exercise in a range of settings. In order to examine theoretical contentions and translate the findings, it is imperative to implement measurement tools that operationalize the constructs in an accurate and reliable way. The original validation of the EBBS proposed a nine-factor structure for the research tool, examined the EBBS factor structure, and suggested that various factors are important for the testing of the perception of exercise benefits and barriers, whereas a few items and factors may not be vital.

Background: The prevalence of musculoskeletal (MSK) conditions is increasing, and although current guidelines for physical activity attempt to combat this, many fail to achieve the recommended targets. The present study sought to investigate whether regular tennis participation is more effective at enhancing MSK function than meeting the current international physical activity guidelines.

Hypothesis: Tennis players will display significantly enhanced MSK function when compared with age-matched healthy active nonplayers.

This paper explores the role of immigrant-serving agencies in facilitating access to dementia services and supports provided by dementia service agencies (particularly the health authority and local chapters of the Alzheimer Society) through their propensity to develop trusting relationships between staff and clients. Our research is a qualitative case study of Punjabi and Korean speakers living in the Lower Mainland of BC, Canada. Data are drawn from interviews with 15 dyads of persons with dementia and their family caregivers (10 Punjabi, 5 Korean), six focus groups (one focus group with each of 8-10 older men, older women, and mixed gender working age adults in each community).

Immigrant older adults are increasingly moving into long term residential care (LTRC) homes; however, most were designed and continue to be run in accordance with Anglocentric norms and values. Participation and interest in Family Councils-through which they might collectively voice concerns-was low within our purposive sample of nine Chinese-origin residents living in LTRC homes and 11 family carers. Our study, conducted in two LTRC homes in British Columbia, Canada between January and March 2016, further explored participants' perceptions of quality of care by staff and quality of life of residents.

Absorption has been identified as readiness for experiences of deep involvement in the task. Conceptually, absorption is a key psychological construct, incorporating experiential, cognitive, and motivational components. Although, no operationalization of the construct has been provided to facilitate research in this area, the purpose of this research was the development and examination of the psychometric properties of a sport-specific measure of absorption that evolved from the use of the modified Tellegen Absorption Scale (MODTAS; Jamieson, 2005) in mainstream psychology.

This article proposes the development of an intersectional life course perspective that is capable of exploring the links between structural inequalities and the lived experience of aging among racialized older people. Merging key concepts from intersectionality and life course perspectives, the authors suggest an analytic approach to better account for the connections between individual narratives and systems of domination that impinge upon the everyday lives of racialized older people. Our proposed intersectional life course perspective includes four dimensions: 1) identifying key events and their timing, 2) examining locally and globally linked lives, 3) exploring categories of difference and how they shape identities, 4) and assessing how processes of differentiation, and systems of domination shape the lives, agency and resistance among older people.

This pilot project asked: How do ethnically diverse older adult residents of assisted living (AL) facilities in British Columbia (BC) experience quality of life? And, what role, if any, do organizational and physical environmental features play in influencing how quality of life is experienced? The study was conducted at three AL sites in BC: two ethnoculturally targeted and one nontargeted. Environmental audits at each site captured descriptive data on policies, fees, rules, staffing, meals, and activities, and the built environment of the AL building and neighborhood. Using a framework that understands the quality of life of older adults to be contingent on their capability to pursue 5 conceptual attributes-attachment, role, enjoyment, security, and control-we conducted 3 focus groups with residents (1 per site) and 6 interviews with staff (2 per site).

The 'Pathways to Diagnosis' study captured the experience of the prediagnosis period of Alzheimer's disease and related dementias through indepth interviews with 29 persons with dementia and 34 of their family caregivers across four sites: anglophones in Calgary, francophones in Ottawa, Chinese-Canadians in Greater Vancouver and Indo-Canadians in Toronto. In this cross-site analysis, we use the 'Candidacy' framework to comprehensively explore the challenges to securing a diagnosis of dementia in Canada and to develop relevant health and social policy. Candidacy views eligibility for appropriate medical care as a process of joint negotiation between individuals and health services, which can be understood relative to seven dimensions: identification of need, navigation, appearances at services, adjudication by providers, acceptance of/resistance to offers, permeability of services and local conditions.

The Seniors Support Services for South Asian Community (S4AC) project was developed in response to the underutilization of available recreation and seniors' facilities by South Asian seniors who were especially numerous in a suburban neighbourhood in British Columbia. Addressing the problem required the collaboration of the municipality and a registered non-profit agency offering a wide range of services and programs to immigrant and refugee communities. Through creative outreach and accommodation, the project has engaged more than 100 Punjabi-speaking seniors annually in diverse exercise activities.

Article Synopsis
  • Consumers ingest various pesticide residues through their diets, leading to EU regulations that assess both individual pesticide effects and their combinations, which poses a challenge for toxicology.
  • This study focuses on the additive effects of various antifungal (triazole) pesticides and other chemical class pesticides on hormone production in a human placental cell line, revealing pronounced inhibition of progesterone production with triazoles.
  • While triazoles and the fungicide prochloraz showed hormone-related effects, other pesticides like chlorpyrifos and triflusulfuron-methyl did not impact steroid hormone production or CYP enzyme expression significantly.

Using a cross-sectional qualitative design involving focus groups and interviews, we sought to gain a more detailed understanding of adolescents' physical activity, eating habits and health perceptions during the transition from secondary school (or high school) to work. Based on thematic analyses, three themes were extracted: (1) perceptions of lifestyle and health, (2) changes in priorities and (3) passive acceptance of internal and external influences on physical activity and diet. Poor diet and physical inactivity appeared to reflect participants' amotivation towards health behaviours, reluctance to divert from perceived peer norms and efforts to assert independence from parents.

Introduction: Self-management programmes are complex interventions aimed at improving the way individuals self-manage chronic conditions, but there are questions about the overall impact of these programmes on disadvantaged populations, in terms of their capacity to engage with and receive the benefits from these initiatives. Given the increased resources being directed towards self-management initiatives, clinicians and policy makers need knowledge on how self-management interventions work for these populations. Most systematic reviews of self-management interventions do not consider the complex interactions between implementation contexts, intervention strategies, and mechanisms that influence how self-management interventions work in real life for disadvantaged groups.

The main purpose of the study was to examine crucial parts of Vealey's (2001) integrated framework hypothesizing that sport confidence is a mediating variable between sources of sport confidence (including achievement, self-regulation, and social climate) and athletes' affect in competition. The sample consisted of 386 athletes, who completed the Sources of Sport Confidence Questionnaire, Trait Sport Confidence Inventory, and Dispositional Flow Scale-2. Canonical correlation analysis revealed a confidence-achievement dimension underlying flow.

Purpose Of The Study: As the prevalence of dementia increases, the pressure to make early diagnoses also increases. Although patients must be able to identify the symptoms to access appropriate services, they may not be equally accessible to all citizens in a multicultural society. Health care professionals and patients may lack a common "first language.

Reducing the use of seclusion is now widely identified as a quality issue for mental health services and reflects recognition of the detrimental impact of seclusion on consumers of services. Despite this, the research evidence suggests that nurses continue to support the use of seclusion in order to maintain a safe environment. The aim of this study was to consider how factors such as Therapeutic Optimism, Job Satisfaction, and Burnout might relate to nurses' attitudes toward seclusion.

The practice of seclusion does not sit comfortably with contemporary Australian mental health policy that emphasizes the provision of mental health services in the least restrictive environment. The negative impact of seclusion on patients and nurses is increasingly being acknowledged. On the other hand, seclusion receives wide support from nurses as a necessary behavior management strategy.
