Creating public value is a key goal of public administrations, both in their daily business and in the growing field of smart government and smart cities, which focuses on IT-enabled innovations in the public sphere. However, many public administrations still struggle with such innovations due to complex technologies, high investments, and the numerous stakeholders involved. To address this issue, some local governments in continental Europe have turned to collaborative innovation approaches, partnering with (semi-)public utility companies in the hope that their additional innovation assets will boost innovativeness. Nevertheless, it remains unclear how exactly such collaborations should be governed to ensure that the focus remains on creating public value, as utility companies may have their own agendas. To explore this question, we conducted a comparative case study in the context of smart city initiatives with four cases in Swiss local governments. Drawing on agency and stewardship theory, we then propose a model of public-value-focused collaborative innovation, enabling us to explore various collaboration characteristics and their effects on public value creation. Our findings suggest that both agency- and stewardship-based collaborations increase innovativeness. However, while agency collaborations tend to produce smart city innovations that mainly serve the utility companies' business interests, stewardship relationships lead to innovations that are focused more on public value creation. As such, our study extends the literature on the effects of collaborative innovation on public value, and it provides practical recommendations on how such collaborative innovation should be designed.  相似文献

Consumer health information studies in library and information science (LIS) are typically not grounded within a theoretical framework. This article explains the importance of theory to LIS research in general, and the specific value of using theories from other disciplines to study consumers' health information-seeking behavior. The argument is supported with two examples: Miller's psychological theory of blunting and monitoring behavior and Granovetter's sociological theory of the strength of weak ties. These theories can be applied by practitioner-researchers to investigate a variety of research problems.  相似文献

The purpose of this study was to establish normative data for regional sweat sodium concentration ([Na+]) and whole-body sweating rate in athletes. Data from 506 athletes (367 adults, 139 youth; 404 male, 102 female) were compiled from observational athlete testing for a retrospective analysis. The participants were skill/team-sport (including American football, baseball, basketball, soccer and tennis) and endurance (including cycling, running and triathlon) athletes exercising in cool to hot environmental conditions (15–50°C) during training or competition in the laboratory or field. A standardised regional absorbent patch technique was used to determine sweat [Na+] on the dorsal mid-forearm. Whole-body sweat [Na+] was predicted using a published regression equation (y = 0.57x+11.05). Whole-body sweating rate was calculated from pre- to post-exercise change in body mass, corrected for fluid/food intake (ad libitum) and urine output. Data are expressed as mean ± SD (range). Forearm sweat [Na+] and predicted whole-body sweat [Na+] were 43.6 ± 18.2 (12.6–104.8) mmol · L–1 and 35.9 ± 10.4 (18.2–70.8) mmol · L–1, respectively. Absolute and relative whole-body sweating rates were 1.21 ± 0.68 (0.26–5.73) L · h–1 and 15.3 ± 6.8 (3.3–69.7) ml · kg–1 · h–1, respectively. This retrospective analysis provides normative data for athletes’ forearm and predicted whole-body sweat [Na+] as well as absolute and relative whole-body sweating rate across a range of sports and environmental conditions.  相似文献

This study aimed to examine player perceptions and biomechanical responses to tennis surfaces and to evaluate the influence of prior clay court experience. Two groups with different clay experiences (experience group, n = 5 and low-experience group, n = 5) performed a 180° turning movement. Three-dimensional ankle and knee movements (50 Hz), plantar pressure of the turning step (100 Hz) and perception data (visual analogue scale questionnaire) were collected for two tennis courts (acrylic and clay). Greater initial knee flexion (acrylic 20. 8 ± 11.2° and clay 32.5 ± 9.4°) and a more upright position were reported on the clay compared to the acrylic court (< 0.05). This suggests adaptations to increase player stability on clay. Greater hallux pressures and lower midfoot pressures were observed on the clay court, allowing for sliding whilst providing grip at the forefoot. Players with prior clay court experience exhibited later peak knee flexion compared to those with low experience. All participants perceived the differences in surface properties between courts and thus responded appropriately to these differences. The level of previous clay court experience did not influence players’ perceptions of the surfaces; however, those with greater clay court experience may reduce injury risk as a result of reduced loading through later peak knee flexion.  相似文献

Equity and widening participation (EWP) initiatives in Australia are increasingly reimagined in policy as sites where participants are constructed as competitor-individuals, with education considered only in terms of employability, social mobility and nation-state market competition. In the context of EWP outreach, and with school students in particular, this can transpire into demands for narrow forms of ‘legitimate’ aspirations. Goffman defines obscenity as when (1) the very intimate is forced into the public sphere, while (2) the humanising dimensions or contexts are stripped away, with an example being pornography—where intimate encounters are reproduced as de-contextualised acts while being made public. This article argues that dominant approaches to practicing and evaluating EWP risk obscene consequences if they force community members to present static future-oriented valuations of intimate, fluid aspirations and experiences of education against a backdrop of increasingly individuated, competitive and standardised educational institutions. In this article, firstly we detail the context to establish a foundation for theorising consequences of particular socio-educational discursive practices. Secondly, we engage with notions of frame, keying and fabrication as a toolbox to reveal some of the unintended (obscene) dynamics risked via certain approaches to programmatic practice and evaluation. Thirdly, we review the diversity of approaches to evaluation (and their attendant debates), highlighting the importance of these debates and diversities, making a case against methodological imperialism.  相似文献
