Current literature focusing on young people’s digital technology use often reflects concerns that they may live virtual lives and withdraw from locally geographically situated spaces. It assumes the existence of a split between offline and online ‘worlds’ corresponding to ‘real ‘and ‘non-real’ respectively. This article reports research findings on how young people locate new social media technologies in their daily lives with particular focus on the relationship between their online and offline experiences. The voices of the young people guided the research, which found that their social media use contradicts conventional narratives of moral panic about the alleged unreality and fearful dangers of online spaces for young people.  相似文献

This paper presents a strategic planning approach which provides methods for analysing hospitals in relation to their environment and for assessing their community dependency. Hospitals must not only focus on their clienteles but must also plan their future in relation to the needs of their constituency while taking into account the other elements of the health services network. The proposed approach also takes into account the need for all the actors concerned with the future of the hospital to become involved through an active-reactive-adaptive process.  相似文献

To date, few studies have focused on employee reactions to the quality-related aspects of the introduction of New Public Management (NPM). The aim of this study was to investigate the effects on employee strain and satisfaction of the implementation NPM in a public service organization. The study was designed as an empirical examination of the 'context-dependent approach' ( Edwards, Collinson, & Rees, 1998 ). This approach suggests that effects of an organizational change depend on the context of the implementation, i.e. organizational aspects (implementation strategies), job content and job context dimensions. They employed a single-case longitudinal design. The case was a large municipal service unit responsible for the public housing system of a city in Austria. The sample consisted of 217 employees. Measurements were taken before the organizational change, and at two different times during the change process. While the implementation of NPM can be considered to have been an organizational success (increase in customer satisfaction), it was accompanied by increases in job strain, and, at the same time, mixed results in job satisfaction. Less qualified employees mainly responsible for the customer interface experienced the organizational change most negatively. Using structural equation modelling, the context-dependent approach was empirically confirmed. Job control, role clarity and information were found to be the most important job and organizational resources.  相似文献

The exposure of employees of different contracting firms to chemical pollutants was assessed during the five-week biennial maintenance shut-down of an isocyanate (TDI) synthesis plant. This assessment was mainly based on personal sampling, but work-related constraints occasionally required that area samples be used instead. Many tasks were carried out during the shut-down procedure (dismantling of reactors, installation of insulation, refection of kilns, cleaning, painting, electricity, etc.), thereby causing the employees of the contracting firms to be exposed to different kinds of pollutants, including products used or manufactured in the process (solvents, TDI and its synthesis intermediates), and products specific to the contractors' activity (welding fumes, crystalline silica, mineral fibers of heat insulation). The highest level of exposure (mainly to TDI) was found for the mechanical engineering activities undertaken during the dismantling of reactors and for cleaning activities. It was demonstrated that there was much variability in day-to-day exposure levels, and occasionally in the exposure levels encountered during a given shift. Cases of concomitant exposure to TDI (mainly short-term exposures) and other pollutants due to simultaneous activities from different tasks in the same area (co-activity) were also observed. Both the need for, and limitations of personal protective equipment (mainly respiratory) are stressed. Special emphasis is put on the responsibility of the owner of the facilities in helping the contractors in the organization of a health and safety policy.  相似文献

Parents of children with disabilities interact with a wide range of service providers in order to assure appropriate services for their children. While some actions performed by professionals are viewed as helpful, many are viewed as obstructive. Surveys completed by over 120 parents identified past actions perceived to be helpful and those thought to be unhelpful as well as identification of professionals associated with those actions. Using the critical incident technique, narrative responses were based on actual experiences that parents described. Parents were also asked to articulate specific actions they would like professionals to take in the future. Over half of the responses request desired relationships with professionals that focus on respect, collaboration, communication and information sharing. Implications for pre-professional training are discussed.  相似文献

Specific efficacy criteria were defined by the International Headache Society for controlled clinical trials on acute migraine. They are derived from the pain profile and the timing of rescue medication intake. We present a methodology to improve the analysis of such trials. Instead of analysing each endpoint separately, we model the joint distribution and derive success rates in any criteria as predictions. We use cumulative regression models for each response at a time and a multivariate normal copula to model the dependence between responses. Parameters are estimated using maximum likelihood. Benefits of the method include a reduction in the number of tests performed and an increase in their power. The method is well suited to dose–response trials from which predictions can be used to select doses and optimize the design of subsequent trials. More generally, our method permits a very flexible modelling of longitudinal series of ordinal data. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

Two major currents of theory have striven to explain the driving force behind the post-Communist transformation in central Europe since 1989. Based on the absolute rationality of actors, the so-called standard approach implies radical public policies that mark a break with the legacy from the preceding period. However it has turned out to be unable to account for the permanence of certain elements from the past. The “path-dependence” approach tries to understand institutional continuities as a reworking of accumulated experiences. However it has not managed to explain phenomena signaling a radical break in behavior patterns. This analysis of a technological change in a Polish firm combines the two dimensions of rupture and continuity by distinguishing between the introduction of change and forms of adaptation and learning by various categories of actors.  相似文献

OBJECTIVE: The authors assessed the knowledge, beliefs about, and practices of vaginal douching among women attending 2 universities in the southeastern United States. PARTICIPANTS: There were 416 participants in this study; 46.9% were black and 44.5% were white. METHODS: The authors administered a 30-item questionnaire to women enrolled in health-related and social science courses at 2 southeastern universities. RESULTS: Approximately 38% of participants reported vaginal douching, mostly for hygienic reasons (70.7%). Most women first learned about douching from their mother. Douching was more common and more frequent among black women (48%) than among white women (27%). Age of first douche correlated positively with age of first sexual intercourse and age of first period. CONCLUSION: Women who had been informed not to douche by a healthcare professional were less likely to have douched within the past 6 months than were women who were not given this information. Misconceptions about douching are common and should be addressed by healthcare professionals.  相似文献
