In Australia and in many parts of the world, older people participate in line dancing. Our phenomenological study explored whether attending a regular line dancing class might offer a group of older people opportunities for active and successful ageing. Our research investigated the meanings and practices fostered in a community line dancing class in Melbourne. We gathered data via an interview with the teacher of the group, observation of a class and two focus group interviews with 25 members. Data were analysed using Interpretative Phenomenological Analysis that is reported thematically under headings of: Belief in the efficacy of line dancing, Physical and emotional benefits, YouTube clips as instructional reinforcement and promotion, and Socialising. The findings show that participation in the class offered older student’s opportunities for dance and music engagement, active and successful ageing, health and well-being, social connection and purposeful leisure. The teacher of the class modelled serious and successful leisure and advocates for dance as holistic training for older people. We position our participants on a continuum of leisure engagement that ranges from the casual to the serious. Further research is required to support arguments for the efficacy of dance as a leisure pursuit for older adults.  相似文献

As the influence of online consumer reviews grows, deceptive reviews are a worsening problem, betraying consumers' trust in reviews by pretending to be authentic and informative. This research identifies factors that can separate deceptive reviews from genuine ones. First, we create a novel means of detection by contrasting authentic versus fake word patterns specific to a given domain (e.g., hotel services). We use a survey on a crowdsourcing platform to obtain both genuine and deceptive reviews of hotels. We learned the word patterns from each category to discriminate genuine reviews from fake ones for positively and negatively evaluated reviews, respectively. We show that our All Terms procedure outperforms current benchmark methods in computational linguistics and marketing. Our extended analysis reveals the factors that determine fake reviews (e.g., a lack of details, present- and future-time orientation, and emotional exaggeration) and the factors influencing people's willingness to write fake reviews (including social media trust, product quality consciousness, deal proneness, hedonic and utilitarian consumption, prosocial behavior, and individualism). We also use our procedure to analyze more than 250,000 real-world hotel reviews to detect fake reviews and identify the hotel and review characteristics influencing review fakery in the industry (e.g., star rating, franchise hotel, hotel size, room price, review timing, and review rating).  相似文献

Canadian fruit and vegetable markets were significantly impacted by the spread of the novel coronavirus SARS-CoV-2 (and COVID-19 disease), beginning in March 2020. Due to the closure of restaurants, bars, and schools, produce growers and distributors were forced to shift supplies almost entirely from the foodservice to the retail channel. Shippers reported labor and logistical constraints in making the change, but the fresh produce supply chain remained robust. In the long term, we expect lasting changes in consumers’ online food-purchasing habits, heightened constraints on immigrant labor markets, and tighter concentration in fresh produce distribution and perhaps retailing.  相似文献

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

In this article, we contribute to sociological literatures on morality, professional and institutional contexts, and morally stigmatized ‘dirty work’ by emphasizing and exploring how they mutually inform one another in lawyers’ work activities. Drawing on interview data with 58 practitioners in the commercial legal industry in Singapore, we analyze how they experience professional and institutional constraints on the expressions of morality in their work. Our findings illustrate how a dominant managerial and economic focus maintains and reproduces a constrained form of morality, limited to instrumental, utilitarian and commercial ends, and subordinated to lucrative client and firm interests. We discuss our findings in terms of the need to research and reform professions in ways that support more rounded and unconstrained moral reflexivity and autonomy in how work is undertaken and valued. This in turn has implications for how organizations and professions might achieve alternative moral institutional orders, and for legal work to avoid the moral and social taints of dirty work.

We use farm diary data from Taiwan in the 1920s and 1930s to estimate the impacts of a state‐wide tenancy reform on tenants’ investment in the farmland and production outcome. The reform, commencing in 1922, enhanced the tenure security for the tenants by promoting written contracts that extended tenure length from 1 year to 5–6 years, and by establishing government‐sponsored organizations for dispute settlements. Our estimations rely on a difference‐in‐difference framework, where self‐cultivated farms are used as the control group. We find that the reform encouraged tenants to make investments in the irrigation and drainage system of the farms, which is expected to have long‐lasting benefits for production. The improved irrigation/drainage system led to significant efficiency gains for the farms. In contrast, the reform did not affect tenants’ usage of fertilizer much, which benefits production for only a crop season or a year.  相似文献

This paper analyzes hospital characteristics that are associated with higher average costs and charges for venipuncture, computed tomography procedures (computerized axial tomography [CAT] scans), and electrocardiograms (EKG). Using data from a Medicare database, our results indicate that higher wages, larger hospital sizes, and greater service quality are associated with higher procedure costs, whereas system membership is generally associated with lower procedure costs. Blinder‐type decompositions, which are the main focus of this study, suggest (a) that venipuncture costs are about 17% to 19% lower at proprietary hospitals than at nonprofit or government hospitals, (b) CAT scan costs are about 6% to 12% lower at nonprofit hospitals than at proprietary and government hospitals, and (c) that EKG costs are about 3% lower at proprietary hospitals than at nonprofit or government hospitals. Lastly, large portions of each of these differences are found to be due to both differences in mean values of the hospitals' characteristics by ownership type and differences in the mechanism by which the hospitals' characteristics are transmitted to procedure costs.  相似文献

The allocation of time between leisure activities and work has been extensively analysed in academic literature. However, leisure time is limited and there may not be sufficient time to enjoy all the leisure activities desired. Hence, this article considers the allocation of time between substitute leisure activities. International football tournaments provide an opportunity to consider consumers’ preferences for watching football and films in a quasi-natural experimental setting. A trade-off between these leisure activities is identified using a difference-in-difference methodology. Using an original, four-country data set, a large and robust negative effect of mega sports events on cinema admissions is identified.  相似文献

The long‐term fracturing of the labour movement has led to increased attention to employee coping practices under new management practices and labour processes. However, the literature caters little for the recent rise of employees taking to social networking sites (SNSs), such as Facebook, to find ways to cope with the pressures of contemporary employment. To explore the self‐organised coping qualities of SNSs, interviews were conducted with front line workers, employed by a large anti‐trade union US retailer, who contribute to a self‐organised Facebook group set up as a place for fellow employees to deal with collective employment‐related problems. The main findings suggest employee self‐organised Facebook groups represent an important development and extension to the coping practices available to individual and groups of employees. The main implication of the findings is that Facebook groups appear to strengthen and widen the options for employee resilience in an age of continuing trade union retreat.  相似文献
