Seafood in the adolescent diet has many benefits, yet a number of adolescents do not consume the recommended levels. Despite this the consumption of seafood by younger consumers has received scant attention in the extant literature. Previous studies on adolescents’ food‐related behaviour tend to focus on general choice mechanisms or perceptions of food and mainly relate to fruit and vegetable intake. The present study seeks to address this gap through investigating the impact of family upon the consumption of seafood by younger consumers through exploring adolescents’ attitudes and behaviour in regard to eating seafood. Utilizing an exploratory qualitative methodology, seven focus groups of adolescents aged 13–19 years were conducted at two schools in South West England. Discussions covered a range of issues related to adolescent seafood consumption. The use of thematic content analysis found that the family, and parents in particular, exert high levels of influence over adolescents’ consumption of seafood both at home and when dining out. The parent who does the shopping and cooking has the greatest role. Sibling preferences and dietary choices also influence whether seafood is served in the home. Of value to researchers and management are the insights gleaned into the influences on adolescents’ attitudes towards and behaviour in regard to eating seafood. In particular, encouraging seafood consumption will rely upon interventions aimed at both parents and children and need to take into account adolescents’ diet and lifestyle preferences, while also acknowledging the influence of peers and the school food environment. 相似文献
Technical change, technical efficiency and multifactor productivity indices are reported for a multiple-output, multiple-input production technology using Chinese provincial data for the 1979-95 period. Results show significant variation in productivity change from year to year and province to province. Using panel methods, we regress the three production indices on several factors important in explaining productivity changes. Decollectivisation in the early 1980s accounts for a significant expansion of the frontier, while rural industrialisation decreased agricultural productivity. Productivity is also sensitive to relative grain prices, to natural disasters such as flood and drought, and proximity of the provinces to coastal areas. 相似文献
The commodification of many food products, combined with increasing market share of supermarkets, has increased the importance of point of sale (POS) strategies in specialty food retailers such as fishmongers. This study seeks to develop strategies to improve the retailing of seafood in fishmongers, specifically oysters, an underutilized species; although they are eaten by many consumers, purchase frequency is low. A literature review identifies the key drivers and barriers to oyster consumption and the information consumers want at POS. Based on these findings, a retailing strategy is developed and tested in two consumer focus groups with results informing revisions to the recommended retail strategy, importantly including a change in collateral from a production focus to a consumption focus. This study contributes to theory and practice by bringing together the existing literature on drivers and barriers and consumer information requirements about oysters to develop and to test practical retail strategy concepts. 相似文献
In data envelopment analysis (DEA), there are two principal methods for identifying and measuring congestion: Those of Färe et al. [Färe R, Grosskopf S. When can slacks be used to identify congestion. An answer to W. W. Cooper, L. Seiford, J. Zhu. Socio-Economic Planning Sciences 2001;35:1–10] and Cooper et al. [Cooper WW, Deng H, Huang ZM, Li SX. A one-model approach to congestion in data envelopment analysis. Socio-Economic Planning Sciences 2002;36:231–8]. In the present paper, we focus on the latter work in proposing a new method that requires considerably less computation. Then, by proving a selected theorem, we show that our proposed methodology is indeed equivalent to that of Cooper et al. 相似文献
Objective: To evaluate cost-effectiveness of brentuximab vedotin in patients with relapsed/refractory Hodgkin lymphoma who have received autologous stem cell transplantation, from a Scottish healthcare payer perspective.
Methods: A Microsoft Excel-based partitioned survival model comprising three health states (progression-free survival [PFS], post-progression survival, and death) was developed. Relevant comparators were chemotherapy with or without radiotherapy (C/R) and C/R with intent to allogeneic hematopoietic stem cell transplantation (alloSCT). Data were obtained from the pivotal phase II single-arm trial in 102 patients (SG035-0003; NCT00848926), a systematic literature review and clinical expert opinions (where empirical evidence was unavailable). PFS and overall survival for brentuximab vedotin were estimated using 5-year follow-up data from SG035-0003, and extrapolated using event rates observed for comparator treatments from published survival data. Resource use included drug acquisition and administration; alloSCT; treatment of adverse events; and long-term follow-up. Deterministic and probabilistic sensitivity analyses were conducted to evaluate the impact of uncertainty.
Results: In the base case, the incremental cost-effectiveness ratio (ICER) for brentuximab vedotin was £38,769 per quality-adjusted life year (QALY) vs C/R, whereas C/R with intent to alloSCT was dominated by brentuximab vedotin. ICERs for brentuximab vedotin generated by the deterministic sensitivity analysis ranged between £32,000–£54,000 per QALY. Including productivity benefits reduced the ICER to £28,881 per QALY.
Limitations: Limitations include lack of comparative data from this single arm study and the heterogeneous population. Inconsistent baseline characteristic reporting across studies prevented complete assessment of heterogeneity and the extent of potential bias in clinical and cost-effectiveness estimates.
Conclusions: Although the base case ICER is above the threshold usually applied in Scotland, it is relatively low compared with other orphan drugs, and lower than the ICER generated using a previous data cut of SG035-0003 that informed a positive recommendation from the Scottish Medicines Consortium, under its decision-making framework for assessment of ultra-orphan medicines. 相似文献
This study drew on three theoretical perspectives – attribution theory, power, and role identity theory – to compare the job-related outcomes of sexual harassment from organizational insiders (i.e., supervisors and co-workers) and organizational outsiders (i.e., offend- ers and members of the public) in a sample (n = 482) of UK police officers and police support staff. Results showed that sexual harassment from insiders was related to higher intentions to quit, over-performance demands, and lower job satisfaction, whereas sexual harassment from outsiders was not significantly related to any of the outcome variables investigated. We also examined two moderator variables: equal opportunity support and confidence in grievance procedures. Consistent with our hypotheses, equal oppor- tunity support mitigated the effects of sexual harassment from supervisors on intent to quit and over-performance demands. Confidence in grievance procedures moderated the relationship between sexual harassment from supervisors and all outcome variables. Implications for theory and practice are discussed. 相似文献
ABSTRACTThis article examines parents' leisure experiences in relation to their child's coming out process and developing lesbian, gay, and bisexual (LGB) identity. Thirteen heterosexual-identifying parents (seven mothers and six fathers) from Canada and the United States were interviewed about the social context and relational aspects of their leisure experiences (e.g., special events and holidays, friends, co-participants, co-workers). Analysis showed that leisure contexts could be altered in relation to their child's developing LGB identity and cultural norms related to heterosexism and homophobia. Three main themes that best reflected the mothers' and fathers' experiences emerged: (a) grieving heterosexist ideals and reframing familial expectations, (b) encountering homophobia and the loss of community, and (c) coming out of the family home and creating a supportive network. 相似文献
