This article explores the work of a group of ward leaders who worked in a large acute NHS Trust in London in identifying the need for practice development in their clinical settings and their own leadership development needs. The ward leaders worked with a facilitator over a period of 6 months to develop knowledge, skills and experience in leading practice developments. The project was deliberately focused on helping the ward leaders become aware of the need for change and increase their potential as leaders of changes arising from the project. The ward leaders worked with the facilitator (the lead author) over a 7-month period, utilising a variety of integrated developmental and data collection techniques. The methods employed included reflection on practice, observation of practice, discussions with practitioners, 360-degree feedback and the use of a variety of creative arts. The project was based on the narrative framework of Frank (1995), and this framework was utilised to shape the interpretation of the processes and outcomes of the project. This article thus presents the combined narrative journey of the facilitator and the participants.  相似文献

In recent years, Australian films have failed to capture the public’s attention at the Australian box office. Why? Do Australians have an aversion to their own films? Or does the release strategy—advertising/publicity expenditure and opening number of screens—explain the lacklustre performance? We find that even though Australian films are generally advertised more heavily and released more widely than non-Australian films, ceteris paribus, they earn less at the box office. We also analyse a subsample of our data for which Film Finance Corporation funding information is available and find that government subsidies have no impact on a film’s financial success at the box office.  相似文献

The aim of this study was to establish whether asymmetry of the strength of the leg and trunk musculature is more prominent in rowers than in controls. Nineteen oarsmen and 20 male controls matched for age, height and body mass performed a series of isokinetic and isometric strength tests on an isokinetic dynamometer. These strength tests focused on the trunk and leg muscles. Comparisons of strength were made between and within groups for right and left symmetry patterns, hamstring :quadriceps ratios, and trunk flexor and extensor ratios. The results revealed no left and right asymmetries in either the knee extensor or flexor strength parameters (including both isometric and isokinetic measures). Knee extensor strength was significantly greater in the rowing population, but knee flexor strength was similar between the two groups. No difference was seen between the groups for the hamstring:quadriceps strength ratio. In the rowing population, stroke side had no influence on leg strength. No differences were observed in the isometric strength of the trunk flexors and extensors between groups, although EMG activity was significantly higher in the rowing population. Patterns of asymmetry of muscle activity were observed between the left and right erector spinae muscles during extension, which was significantly related to rowing side ( P < 0.01). These observations could be related to the high incidence of low back pain in oarsmen.  相似文献

Engaging in relationships with other organizations is one way for nonprofit community sport organizations (CSOs) to acquire needed resources, knowledge, and other social benefits while achieving important public purposes and building community cohesion. This study explored the processes and outcomes of interorganizational relationships in CSOs through semi-structured interviews with presidents of these organizations (N = 20). The findings revealed key relationship processes including trust, consistency, balance, and engagement as well as specific management skills. The findings also revealed that relationships impacted CSOs through enabling improvements to program/service quality and operations, and enhancing community presence. The study contributes to the interorganizational relationship literature and our understanding of how relationships advance organizational goals in this small nonprofit context.  相似文献

The ability to determine a specific location on a football (soccer) pitch from television footage would provide a cost-effective method of obtaining competition-specific information on many professional and international teams. This study presents the accuracy and reliability of a new method of calculating ball location from simulated television coverage and known pitch markings. The coordinates of 99 markers of known location on a football pitch were digitized from video. An intersection point was determined from the equations of two lines that form pitch markings and the relationship from this point to other known pitch coordinates was calculated using a curve-fitting based method. Average error between known and reconstructed measures was 0.21 m for pitch width and 0.11 m for pitch length from a view simulating television coverage. Inter- and intra-rater reliability analyses showed researchers could consistently reconstruct pitch locations to within less than half a metre. The accuracy and reliability of this method will be sufficient for most practical uses in an applied sport environment, although the level of accuracy required will depend on the specific application. This method could be applied to other sports to determine specific locations on a pitch or court or to improve current competition analysis systems.  相似文献

Purpose

To determine the opinions and attitudes toward exercise in people with chronic obstructive pulmonary disease (COPD) who had completed a randomised controlled trial of 12-months maintenance exercise.

Methods

Participants were eligible for recruitment to the maintenance exercise study if they had COPD and had completed an 8-week pulmonary rehabilitation program. They were randomized into an Intervention Group (IG) that consisted of once weekly, supervised hospital-based maintenance exercise plus home exercise for 12 months or a Control Group that undertook unsupervised home maintenance exercise for 12 months. At the end of the 12 months, participants completed a survey consisting of 23 questions using a visual analogue scale (VAS) of 100 mm.

Results

Forty-eight participants completed the 12 month study and 36 participants (75%) completed the survey [IG mean (SD): age 65 (8) years, FEV1 58 (20) % predicted; CG: age 66 (8) years, FEV1 67 (17) % predicted]. No between group difference was found for the importance of exercise, the benefits of the program or the importance of support from the physiotherapist. However, the IG reported exercising more regularly, having more enjoyment of being involved in the maintenance exercise program, greater benefit in general well-being, and better physical fitness.

Conclusions

At the completion of the 12 month exercise study, the survey results showed that all participants reported positive attitudes towards both supervised and unsupervised maintenance exercise programs, with the IG reporting greater benefits.Key Words: COPD, survey, maintenance exercise program  相似文献

This paper explores the concept of apprenticeship in the context of the professional formation of knowledge workers. It draws on evidence from research conducted in two knowledge intensive organizations: a research-intensive, elite university; and a ‘cutting edge’ software engineering company. In the former, we investigated the learning environments of contract researchers, whilst in the latter, we focused on the learning environments of software engineers. Both organisations have ‘global’ reach in that they operate within international marketplaces and see themselves as international players. The paper asks to what extent the important role of maturation with regard to the formation of expertise is being undermined by the pressurised nature of contemporary workplaces (in both the public and private sectors). It argues that conceiving the professional formation of knowledge workers as apprenticeship provides a way forward to improve the way employers construct and support that formation.  相似文献

Conversation is key and as the communication landscape shifts rapidly, harnessing ‘e’ is pivotal in extending ‘story’ as digital evolves, catapulting publishing from analogue to digital. Harnessing ‘e’ is an exciting and effective way to add value, but for ‘e’ to be implemented successfully and seamlessly requires more than a standard ‘roll out’ of strategy. Staying Single [1] was my MA dissertation project in the form of a fictional blog that bridged a fictitious digital world with a real physical one as I supplemented Sophie’s story with souvenirs, additional digital content, UGC, and social media elements, all channelled through Sophie’s fictional storyworld. This study was an investigation into the effects that interactivity and community might bring to contemporary fiction, traditionally published in print form, by women, for women. The presentation of Staying Single as a cross-media, digital story challenged conventional boundaries for story enjoyment and involvement and attempted to vastly expand the story universe, recording how the option for interactivity impacted the story. Readers were offered choices to receive Staying Single through blog feeds, by email or downloaded podcasts, with additional options for involvement through multiple platforms—‘Pulling Power’ ‘relationship’ documentaries, SMS alerts and ‘meeting’ Sophie in Second Life. My current transmedia romantic comedy fiction, Loving NY will push these resources and opportunities further, enhancing and driving the story whilst engaging and interacting with readers. Transmedia storyworld development is extremely fast-moving and with magazines offering web-cam enabled augmented realities and iPhone apps allowing readers to GPS tag co-readers, these are extremely exciting times! To harness ‘e’ is to offer options—levels of immersion and engagement, multi-platform choices, perhaps even linear or non-linear narratives with the intention of organically reaching a wider readership far beyond the restrictions of print based novels.  相似文献

The purpose of this study was to examine the effects of implementing user design strategies within the corporate culture. Using a case study design approach, this article explores the change process within a Fortune 100 company in which users were given significant decision‐making powers. The main focus is on the unique nature of user design in a corporate environment where users become stakeholders in the process, a very different approach from the more typical top‐down management style. The study found that allowing users to design their own day‐to‐day processes gave them a sense of empowerment in their jobs because they could manage how they worked as long as they were meeting company goals. As a result, users were better able to manage their jobs, solve process‐related problems, and increase efficiency.  相似文献
