Increasingly, health organisations and governing bodies in developed countries are paying serious attention to the problem of adult inactivity. Many of the programs designed to increase levels of activity, particularly amongst target populations, such as women, have not been systematically assessed for their effectiveness in recruiting women and helping them maintain activity levels. The purpose of this study was to determine what attracted and sustained women to participate in physical activity programs. Responses from a survey to sport and recreation program providers identified 64 successful programs in the state of Victoria, Australia. Eight of these programs were purposively selected for case study analysis. Data was collected from a focus group with women participants from each of these eight programs. Six core themes emerged from inductive content analysis of the focus groups. The most frequent participant responses related to the social aspects of the exercise environment. Women in the focus groups valued instructor professionalism and instructors’ technical knowledge, however, it was their awareness and sensitivity that participants appreciated most. This exploratory study is important because it reflects the voices of women talking about what made physical activity programs successful for them. The study raises critical questions that should be examined systematically through large-scale survey research and field-based intervention studies, which in turn should stimulate program development to encourage women in physical activity.  相似文献

This article describes the conceptualisation and development of a pedagogical framework to support the design of e‐books for children to enhance literacy development. It emerged from research undertaken within the Q‐Tales international consortium project of the EU's Horizon 2020 Programme for Research and Innovation, where the aim was to facilitate key stakeholders to collaborate and participate in the online production and publication of high‐quality, educational e‐books for children. The pedagogical framework described here sought to answer the question “What concepts and principles undergird the effective design of pedagogically impactful e‐books for children?” It is grounded by the theoretical underpinnings of socio‐constructivism, constructionism and skill theory, and how they relate to children's literacy development. A framework describing different narrative forms and component features, key pedagogical activities appropriate for different stages of reading development and design recommendations regarding the integration of multimedia into e‐books are also central to the pedagogical framework. As well as informing the design of the Q‐Tales infrastructure for children's e‐book design and publication, we hope the guidelines and pedagogical activities enumerated here will be widely useful for those designing and developing digital, interactive narratives, particularly e‐books to enhance children's emerging literacy.  相似文献

Although China is now the largest patent filing country in the world, research on the duration and outcomes of patent examination remains scarce. In this study, we conduct a replication and extension of Harhoff and Wagner’s (2009) work on the determinants of patent examination duration at the European Patent Office (EPO), using a rich dataset covering the population of about 1.1 million invention patent applications to China’s State Intellectual Property Office (SIPO) from 1993 to 2006. By considering all three competing examination outcomes (grant, withdrawal, and refusal) simultaneously, our competing risks analysis replicates many of the results in prior research and confirms that a number of the determinants have differential effects on pendencies for different outcomes. Our analysis also reveals several applicant and application characteristics whose effects on pendencies for specific outcomes differ from prior research. Finally, by incorporating a number of new determinants, we report a set of new findings about their effects on the examination duration for the three outcomes at SIPO.  相似文献

Abstract

Australian football is an indigenous game codified in 1859. In Melbourne, the code’s birthplace, the game remained officially committed to the amateur ideal for over a half-century. Illegal player payments nonetheless became increasingly commonplace. Moreover, periodically rumours swirled of champion footballers taking bribes to ‘play dead’. By the early 1900s, the code’s leading competition, the Victorian Football League (VFL), was derided with the ‘shamateurism’ label. Following a sensational match-fixing investigation that resulted in two players receiving five-year bans, in 1911 the VFL expunged its rule prohibiting player payments. Was the timing merely coincidental or was the League’s historic switch to professionalism a deliberate countermeasure to redirect press attention, renew public confidence, and restore the game’s integrity? By consulting the League’s official records and contemporary press articles, this work examines the overlooked yet discernible linkages between rising match-fixing allegations and the VFL’s decision to eschew amateurism and embrace professionalism. It argues that Australian football offers an instructive historical perspective of a sporting body tackling mounting concerns over corruption, taking back the ascendency by amending its rules to better govern over dishonest players and duplicitous club officials, thereby growing its popularity and restoring public perception of its integrity in the process.  相似文献

Abstract

In two experiments, participants performed visual detection, visual discrimination and decision-making tasks, in which a binary (left/right) response was required. In all experimental conditions, a spoken word (“left”/“right”) was presented monaurally (left or right ear) at the onset of the visual stimulus. In Experiment 1, 26 non-athletes located a target amongst an array of distractors as quickly as possible, in both the presence and absence of spoken cues. Participants performed superiorly in the presence of valid cues, relative to invalid-cue and control conditions. In Experiment 2, 42 skilled netballers completed three tasks, in randomised order: a visual detection task, a visual discrimination task and a netball decision-making task – all in the presence of spoken cues. Our data showed that spoken auditory cues affected not only target detection, but also performance on more complex decision-making tasks: cues that were either spatially or semantically invalid slowed target detection time; spatially invalid cues impaired discrimination task accuracy; and cues that were either spatially or semantically valid improved accuracy and speeded decision-making time in the netball task. When studying visual perception and attention in sport, the impact of concomitant auditory information should be taken into account in order to achieve a more representative task design.  相似文献

The origins of the modern football codes have attracted considerable attention from historians of sport over the past two decades, resulting in a vigorous debate between the self-described ‘revisionists’, led by Adrian Harvey, and the followers of Eric Dunning, dubbed by their opponents as the ‘orthodox’ view. However, this article argues that both sides commit the same methodological errors: an overestimation of the importance of written rules, an ahistoric view of culture and continuity, and a tendency to view the past through the lens of the present. By re-examining the historical record of early forms of football and presenting a broader contextual perspective for the emergence of the football codes in the 1840 to 1880 period, the article aims to address some of the key historiographical issues that confront historians of sport today.  相似文献

Changes in workload are evident during many physical activities. The aim of this study was to assess total substrate metabolism when the temporal placement of a period of higher-intensity work (75% VO 2max ) was varied within a low-intensity exercise session (50% VO 2max ). One experimental trial (higher intensity first) comprised 5 min low-intensity work, followed by 15 min high-intensity work, followed by 40 min low-intensity work. The other trial (low intensity first) comprised 40 min low-intensity work, followed by 15 min high-intensity work, followed by 5 min low-intensity work. The trials were designed to achieve an identical total energy expenditure. Energy expenditure, fat and carbohydrate utilization were estimated by expired gas analysis and compared between conditions. Mean total energy expenditure during the higher-intensity phase was 1076 kJ and 1128 kJ in the high-intensity first and low-intensity first trials respectively (t 6 = -3.76, P = 0.0047). Mean total energy expenditure for the whole trial was 3356 kJ and 3452 kJ in the high-intensity first and low-intensity first trials respectively (t 6 = -3.48, P = 0.0065). Mean whole-trial fat utilization was 1753 kJ and 1857 kJ in the high-intensity first and low-intensity first trials respectively (t 6 = -0.76, P = 0.24). Our findings suggest that changing the temporal placement of higher-intensity work within a low-intensity exercise session has a significant effect on total energy expenditure but not on the rate of fat oxidation.  相似文献
