Resident Perceptions of a Controversial Annual Event

A survey of 880 residents revealed diverse attitudes toward Gold Coast Schoolies Week, an annual high school-leaver celebration characterized by partying and drinking. ‘Conditional supporters’ (33%) or ‘conditional opponents’ (34%) provided complex assessments of costs and benefits, as per social exchange theory, that include considerations of ‘noncosts’ and ‘nonbenefits’. With regard to social representations, ‘opponents’ (18%) are more likely to be influenced by mass media, social circles and negative personal exposure, whilst ‘supporters’ (15%) are more likely to rely on their own and their children’s schoolie experience. Balanced media coverage is one means for improving resident perceptions

Socio-cultural influences on the behaviour of South Asian women with diabetes in pregnancy: qualitative study using a multi-level theoretical approach

BACKGROUND: Diabetes in pregnancy is common in South Asians, especially those from low-income backgrounds, and leads to short-term morbidity and longer-term metabolic programming in mother and offspring. We sought to understand the multiple influences on behaviour (hence risks to metabolic health) of South Asian mothers and their unborn child, theorise how these influences interact and build over time, and inform the design of culturally congruent, multi-level interventions. METHODS: Our sample for this qualitative study was 45 women of Bangladeshi, Indian, Sri Lankan, or Pakistani origin aged 21-45 years with a history of diabetes in pregnancy, recruited from diabetes and antenatal services in two deprived London boroughs. Overall, 17 women shared their experiences of diabetes, pregnancy, and health services in group discussions and 28 women gave individual narrative interviews, facilitated by multilingual researchers, audiotaped, translated, and transcribed. Data were analysed using the constant comparative method, drawing on sociological and narrative theories. RESULTS: Key storylines (over-arching narratives) recurred across all ethnic groups studied. Short-term storylines depicted the experience of diabetic pregnancy as stressful, difficult to control, and associated with negative symptoms, especially tiredness. Taking exercise and restricting diet often worsened these symptoms and conflicted with advice from relatives and peers. Many women believed that exercise in pregnancy would damage the fetus and drain the mother's strength, and that eating would be strength-giving for mother and fetus. These short-term storylines were nested within medium-term storylines about family life, especially the cultural, practical, and material constraints of the traditional South Asian wife and mother role and past experiences of illness and healthcare, and within longer-term storylines about genetic, cultural, and material heritage - including migration, acculturation, and family memories of food insecurity. While peer advice was familiar, meaningful, and morally resonant, health education advice from clinicians was usually unfamiliar and devoid of cultural meaning. CONCLUSIONS: 'Behaviour change' interventions aimed at preventing and managing diabetes in South Asian women before and during pregnancy are likely to be ineffective if delivered in a socio-cultural vacuum. Individual education should be supplemented with community-level interventions to address the socio-material constraints and cultural frames within which behavioural 'choices' are made

Dairy consumption and risk of frailty in older adults: A prospective cohort study

OBJECTIVES: To examine the association between consumption of dairy products and risk of frailty in community-dwelling older adults. DESIGN: Prospective cohort study. SETTING: General population from the older cohort of the Study on Nutrition and Cardiovascular Risk in Spain. PARTICIPANTS: Community-dwelling adults aged 60 and older free of frailty at baseline (N = 1,871). MEASUREMENTS: From 2008 to 2010, food consumption was assessed using a validated diet history. Participants were examined again in 2012 to assess incident frailty, defined as at least three of the five Fried criteria (exhaustion, weakness, low physical activity, slow walking speed, unintentional weight loss). Adjusted odds ratios (OR) for the main confounders were obtained using logistic regression. RESULTS: During follow-up, 134 new cases of frailty were identified. Participants consuming seven or more servings per week of low-fat milk and yogurt had lower incidence of frailty (OR = 0.52; 95% confidence interval (CI) = 0.29-0.90; P for trend = .03) than those consuming less than one serving per week. Specifically, consumers of seven or more servings per week of low-fat milk and yogurt had less risk of slow walking speed (OR = 0.64, 95% CI = 0.44-0.92, P trend = .01) and of weight loss (OR = 0.54, 95% CI = 0.33-0.87, P trend = .02). Consuming seven or more servings per week of whole milk or yogurt (OR = 1.53, 95% CI = 0.90-2.60, P trend = .10) or of cheese (OR = 0.91, 95% CI = 0.52-1.61; P trend = .61) was not associated with incident frailty. CONCLUSION: Higher consumption of low-fat milk and yogurt was associated with lower risk of frailty and, specifically, of slow walking speed and weight loss. Current recommendations to prevent frailty include protein supplementation; thus, although experimental research is needed, increasing the consumption of low-fat yogurt and milk might prevent frailty in older adultsThis work was supported by several sources: a) the Ministry of Health of Spain (FISS grants 09/1626, 09/0104, 12/1166 and 13/00288); b) the European Union FP7- HEALTH-2012-Proposal No: 305483-2 (FRAILOMIC Initiative) and c) Sanofi-Aventi

Cruise visitors’ experience in a Mediterranean port of call

This study aims to provide a better understanding on cruise travel experience by studying cruise ship passengers motivation, satisfaction and likelihood of return to the port of Heraklion (Crete, Greece). From the findings, it is evident that ‘exploration’ and ‘escape’ were among the main motivations of visitors, and ‘product and services’ as well as ‘tour pace’ were significant dimensions in shaping overall satisfaction levels. Nevertheless, onshore activities were restricted to sightseeing and shopping, because of the limited available time. Based on these findings, relevant proposals are made in order to provide positive port experiences

Coping Mediates the Association Between Type D Personality and Perceived Health in Chinese Patients with Coronary Heart Disease

Background: Increasing evidence show that Type D personality is a risk factor for morbidity, mortality, and quality of life of patients with coronary vascular disease. Few studies examined coping as a potential behavioral mechanism to explain the harmful effect of Type D personality. Purpose: This study examined the association between Type D personality, coping, and perceived health among Chinese patients with coronary heart disease (CHD). Methods: One hundred seventeen CHD patients completed the assessments on Type D personality, coping, perceived severity of CHD, and morale. Results: There was no difference on severity of coronary artery stenosis between Type D and non-Type D patients. Compared to the non-Type D patients, the Type D patients perceived higher severity of CHD (5.31±2.41 versus 4.45±2.17, p<0.05) and lower morale (12.67±4.71 versus 15.00±4.43, p<0.05), and used less confrontation (16.90±5.39 versus 20.88±4.95, p<0.001) and more acceptance-resignation coping (10.16±3.50 versus 8.35±3.48, p<0.05). Mediation analyses showed that confrontation coping mediated the association between Type D personality and perceived severity of disease, and acceptance-resignation coping mediated the association between Type D personality and morale after controlling for age, gender, and clinical variables. Conclusion: The Type D patients used maladaptive coping in response to disease. These coping strategies fully mediated the association between Type D personality and perceived health. Implications for integrating coping training into the intervention for patients with a Type D personality are discussed. © 2010 The Author(s).published_or_final_versionSpringer Open Choice, 21 Feb 201

Managing for Political Corporate Social Responsibility: New Challenges and Directions for PCSR 2.0

This article takes stock of the discourse on ‘political CSR’ (PCSR), reconsiders some of its assumptions, and suggests new directions for what we call ‘PCSR 2.0’. We start with a definition of PCSR, focusing on firms’ contribution to public goods. We then discuss historical antecedents to the debate and outline the original economic and political context. The following section explores emerging changes in the institutional context relevant to PCSR and reconsiders some of the assumptions underlying Habermas’ thesis of the postnational constellation. This highlights some neglected issues in previous works on PCSR, including the influence of nationalism and fundamentalism, the role of various types of business organisations, the return of government regulation, the complexity of institutional contexts, the efficiency of private governance, the financialization and digitalization of the economy, and the relevance of managerial sensemaking. Finally, we discuss the contributions to this special issue and relate them to the newly emerging research agenda

Sarco/Endoplasmic Reticulum Ca2+-ATPases (SERCA) Contribute to GPCR-Mediated Taste Perception

The sense of taste is important for providing animals with valuable information about the qualities of food, such as nutritional or harmful nature. Mammals, including humans, can recognize at least five primary taste qualities: sweet, umami (savory), bitter, sour, and salty. Recent studies have identified molecules and mechanisms underlying the initial steps of tastant-triggered molecular events in taste bud cells, particularly the requirement of increased cytosolic free Ca2+ concentration ([Ca2+]c) for normal taste signal transduction and transmission. Little, however, is known about the mechanisms controlling the removal of elevated [Ca2+]c from the cytosol of taste receptor cells (TRCs) and how the disruption of these mechanisms affects taste perception. To investigate the molecular mechanism of Ca2+ clearance in TRCs, we sought the molecules involved in [Ca2+]c regulation using a single-taste-cell transcriptome approach. We found that Serca3, a member of the sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) family that sequesters cytosolic Ca2+ into endoplasmic reticulum, is exclusively expressed in sweet/umami/bitter TRCs, which rely on intracellular Ca2+ release for signaling. Serca3-knockout (KO) mice displayed significantly increased aversive behavioral responses and greater gustatory nerve responses to bitter taste substances but not to sweet or umami taste substances. Further studies showed that Serca2 was mainly expressed in the T1R3-expressing sweet and umami TRCs, suggesting that the loss of function of Serca3 was possibly compensated by Serca2 in these TRCs in the mutant mice. Our data demonstrate that the SERCA family members play an important role in the Ca2+ clearance in TRCs and that mutation of these proteins may alter bitter and perhaps sweet and umami taste perception

Differential expression of a BMP4 reporter allele in anterior fungiform versus posterior circumvallate taste buds of mice

<p>Abstract</p> <p>Background</p> <p>Bone Morphogenetic Protein 4 (BMP4) is a diffusible factor which regulates embryonic taste organ development. However, the role of BMP4 in taste buds of adult mice is unknown. We utilized transgenic mice with LacZ under the control of the BMP4 promoter to reveal the expression of BMP4 in the tongues of adult mice. Further we evaluate the pattern of BMP4 expression with that of markers of specific taste bud cell types and cell proliferation to define and compare the cell populations expressing BMP4 in anterior (fungiform papillae) and posterior (circumvallate papilla) tongue.</p> <p>Results</p> <p>BMP4 is expressed in adult fungiform and circumvallate papillae, i.e., lingual structures composed of non-taste epithelium and taste buds. Unexpectedly, we find both differences and similarities with respect to expression of BMP4-driven ß-galactosidase. In circumvallate papillae, many fusiform cells within taste buds are BMP4-ß-gal positive. Further, a low percentage of BMP4-expressing cells within circumvallate taste buds is immunopositive for markers of each of the three differentiated taste cell types (I, II and III). BMP4-positive intragemmal cells also expressed a putative marker of immature taste cells, Sox2, and consistent with this finding, intragemmal cells expressed BMP4-ß-gal within 24 hours after their final mitosis, as determined by BrdU birthdating. By contrast, in fungiform papillae, BMP4-ß-gal positive cells are never encountered within taste buds. However, in both circumvallate and fungiform papillae, BMP4-ß-gal expressing cells are located in the perigemmal region, comprising basal and edge epithelial cells adjacent to taste buds proper. This region houses the proliferative cell population that gives rise to adult taste cells. However, perigemmal BMP4-ß-gal cells appear mitotically silent in both fungiform and circumvallate taste papillae, as we do not find evidence of their active proliferation using cell cycle immunomarkers and BrdU birthdating.</p> <p>Conclusion</p> <p>Our data suggest that intragemmal BMP4-ß-gal cells in circumvallate papillae are immature taste cells which eventually differentiate into each of the 3 taste cell types, whereas perigemmal BMP4-ß-gal cells in both circumvallate and fungiform papillae may be slow cycling stem cells, or belong to the stem cell niche to regulate taste cell renewal from the proliferative cell population.</p
