We conduct an analysis of 1835 pledges to 10 music production projects hosted on the largest Brazilian crowdfunding platform, namely the Catarse Web site, and we assess the relation between the fundraising accumulation period, the donor–entrepreneur distance and the propensity of donors to back projects. Our results suggest a significantly negative association between distance and the value of capital pledged to projects, which is consistent with the notion that the entrepreneur’s network of close contacts might play a central role in funding. Furthermore, our results contradict the idea that crowdfunding reduces the inhibiting effect of donor–entrepreneur distance. In addition, the results show that a long project exposure is associated with higher values of pledges. These results suggest practical implications for the study of crowdfunding as a financing platform. This study contributes to the literature on the use of crowdfunding as an alternative funding source in a major emerging market.  相似文献   

Effect of a Brazilian Jiu-jitsu-simulated tournament on strength parameters and perceptual responses

This study aimed to analyse the effects of a simulated Brazilian jiu-jitsu (BJJ) tournament on vertical jump performance, grip strength test and perceived effort responses. 22 male BJJ athletes participated in a simulated tournament consisting of three 7 min matches separated by 14 min of rest. Kimono grip strength test (KGST), counter movement jump (CMJ) and rate of perceived exertion (RPE) were measured before and after each match, while RPE of specific areas was assessed after three matches. ANOVA for repeated measures was used to compare strength parameters after each match with the level of significance set at 5%. The key results showed a significant decrease of jump height (p = 0.001) and net vertical impulse in the CMJ (p = 0.031), as well as a reduction of the number of reps in the KGST (p < 0.001). A significant increase of RPE was found throughout the matches (p < 0.001). Considering the RPE in specific areas, no differences were observed between the upper and lower body (p = 0.743). We conclude that the BJJ simulated tournament generated a decrease of performance in both upper and lower limbs and provoked a progressive increase in the effort perception over the matches.  相似文献

Flipping the classroom to teach systematic reviews: the development of a continuing education course for librarians     

Marisa L. Conte  Mark P. MacEachern  Nandita S. Mani  Whitney A. Townsend  Judith E. Smith  Chase Masters  Caitlin Kelley 《Journal of the Medical Library Association》2015,103(2):69-73

Objective:The researchers used the flipped classroom model to develop and conduct a systematic review course for librarians.Setting:The research took place at an academic health sciences library.Method:A team of informationists developed and conducted a pilot course. Assessment informed changes to both course components; a second course addressed gaps in the pilot.Conclusion:The flipped classroom model can be successful in developing and implementing a course that is well rated by students.  相似文献   

Do performance‐based research funding systems affect research production and impact?     

Daniele Checchi  Marco Malgarini  Scipione Sarlo 《Higher Education Quarterly》2019,73(1):45-69

We study the potential impact of introducing performance‐based funding systems (PBFS) on national research systems, using information on the number of publications and their scientific impact (citations or publications in top‐ranked journals) for 31 countries over the period 1996–2016. The analysis is performed both at the aggregate level and looking separately at each of the six main scientific areas identified according to the Organisation for Economic Co‐operation and Development (OECD) classification. On average, PBFS are found to increase the number of publications, though the effect is only temporary and fades after a few years. Looking at the scientific impact, PBFS are found to have a negligible effect on excellence as measured by the share of articles published in the top journals, irrespective of the type of assessment adopted. On the contrary, PBFS have some influence on average research quality, as measured by the number of citations per paper normalised with respect to the field.  相似文献

Knowledge development and advice networks in professional organizations     

Fausto?Di?VincenzoEmail author  Daniele?Mascia 《知识管理研究与实践》2017,15(2):201-213

In this paper, social network analysis techniques and regression models are used to explain the impact of the level of knowledge development on ego-network redundancy in a community of hospital physicians. Our findings document that the level of knowledge development and the extent to which knowledge is homogeneously distributed amongst collaborating physicians are related to the redundancy of their advice networks, albeit with opposite effects. Our results highlight also that the impact of these relationships on network redundancy is moderated based on whether partnering individuals belong to different professional groups. Our results provide valuable input for the management of knowledge networks within professional organizations.  相似文献   

Remarques critques à propos de l'enquête internationale sur la litteratie     

Daniele Manesse 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2000,1(1):407-417

There is no doubt of the necessity and importance of an international comparative inquiry concerning literacy. The difficulties involved in such an inquiry are also incontestable. In France the seemingly improbable results of the survey led to the French authorities – who had no doubt been insufficiently vigilant during the earlier stages of the survey – refusing to make the results public. These results highlight a number of methodological flaws that beset this vast undertaking, drawing attention to the need for better procedural precautions and a more adequate notion of literacy. This article presents a synthesis of the counter-investigations demanded by the French authorities, which justify their doubts on the IALS methods, and opens up a debate on the conception of literacy that was applied in the tests.  相似文献   

A survey of talent identification and development processes in the youth academies of professional soccer clubs from around the world

ABSTRACT

Talent identification (TID) and development (TDE) are large fields in professional soccer and in science. However, TID and TDE processes in youth academies have not been assessed in detail. As such, our aim was to survey professional clubs from around the world about their youth academy TID and TDE processes, with 29 clubs responding to the survey. TID and TDE processes changed as a function of player age. TID processes involved finding the best players locally and regionally, but for older players the search widened to nationally and internationally for the needs of the first team. Clubs used a multidisciplinary approach to TID, but more so with older players. Median number of academy players was 80, 100, and 66 players at 8–11 years, 12–16 years, and 17–21 years, respectively. Annual player turnover in the most recent season (selections/de-selections) was 29% across all age groups, with competition from other clubs cited as a limitation to TID. TDE processes involved weekly matches and 3–5 training sessions per week led by experienced, well-qualified coaches, with most clubs providing players with academic education, residency and transportation services. Our findings extend previous research assessing professional soccer youth academy TID and TDE processes by quantifying worldwide practices.  相似文献
