操纵比赛对于体育竞赛来说具有非常恶劣的影响,因此,打击操纵比赛成为体育界的重要任务。然而,在具体的案件中,打击操纵比赛可能涉及到触犯法律所保护的利益。“卡帕蒂案”显示,在与腐败行为与操纵比赛作斗争的公共利益敏感的仲裁案件中,仲裁员更倾向于支持“公平比赛”,而不是获得证据过程中的“违规行为”。  相似文献   

Effects of strength,explosive and plyometric training on energy cost of running in ultra-endurance athletes     

Nicola Giovanelli  Paolo Taboga  Enrico Rejc  Stefano Lazzer 《European Journal of Sport Science》2017,17(7):805-813

The aim of the present study was to evaluate the effects of a 12-week home-based strength, explosive and plyometric (SEP) training on the cost of running (Cr) in well-trained ultra-marathoners and to assess the main mechanical parameters affecting changes in Cr. Twenty-five male runners (38.2?±?7.1 years; body mass index: 23.0?±?1.1?kg·m^?2; V˙O₂max: 55.4?±?4.0 mlO₂·kg^?1·min^?1) were divided into an exercise (EG?=?13) and control group (CG?=?12). Before and after a 12-week SEP training, Cr, spring-mass model parameters at four speeds (8, 10, 12, 14?km·h^?1) were calculated and maximal muscle power (MMP) of the lower limbs was measured. In EG, Cr decreased significantly (p?<?.05) at all tested running speeds (?6.4?±?6.5% at 8?km·h^?1; ?3.5?±?5.3% at 10?km·h^?1; ?4.0?±?5.5% at 12?km·h^?1; ?3.2?±?4.5% at 14?km·h^?1), contact time (t_c) increased at 8, 10 and 12?km·h^?1 by mean +4.4?±?0.1% and t_a decreased by ?25.6?±?0.1% at 8?km·h^?1 (p?<?.05). Further, inverse relationships between changes in Cr and MMP at 10 (p?=?.013; r?=??0.67) and 12?km·h^?1 (p?<?.001; r?=??0.86) were shown. Conversely, no differences were detected in the CG in any of the studied parameters. Thus, 12-week SEP training programme lower the Cr in well-trained ultra-marathoners at submaximal speeds. Increased t_c and an inverse relationship between changes in Cr and changes in MMP could be in part explain the decreased Cr. Thus, adding at least three sessions per week of SEP exercises in the normal endurance-training programme may decrease the Cr.  相似文献   

Using & Re-using Archive Information for Multimedia Applications: The Virtual Museum of Italian Computer Science History     

Franca Garzotto  Paolo Paolini  Pasquale Savino 《Archives and Museum Informatics》1999,13(2):95-111

The quality of content is a key attribute for assessing the globalquality of a museum application. Unfortunately, producing good content,especially in multimedia digital form, is expensive and time-consuming.One way to reduce the costs without sacrificing quality is to exploitthe concept of information reuse. The idea is to use (portions of) thesame multimedia material in different applications, possibly adapting itfor different contexts, for different categories of users, and fordifferent delivery channels (e.g., on-line and off-line). Informationreuse does not come free. To be effective, it requires a well-organizedenvironment in which information can be easily stored, inspected,retrieved, and adapted for different purposes. This paper describes theapproach adopted in the project ``The Virtual Museum of Italian ComputerScience History', funded by the Italian National Council of Research(CNR). In this project, all the digital material (documents, images,video interviews, etc.) is stored in a digital archive based on amultimedia database with a WWW front-end. The archive is designed forspecialists only: members of the editorial board of the project;researchers in the history of science; application developers (whoare looking for interesting content to include in their CD-ROMs or Websites). Each research group involved in the project extracted andadapted from the digital archive the multimedia material needed to builda different hypermedia application in two ``versions' – WWW andCD-ROM. These applications, both on-line and off-line, strongly reuse(portions of) the digital archive content, but organize and present itwith a totally different style, to address the needs of non-specialists(e.g., people who have some interest, or curiosity, in the history ofItalian computer science).  相似文献   

The social-cognitive mechanisms regulating adolescents' use of doping substances     

Lucidi F  Zelli A  Mallia L  Grano C  Russo PM  Violani C 《Journal of sports sciences》2008,26(5):447-456

In this study, we assessed the longitudinal effects of social-cognitive mechanisms on the self-reported use of doping substances and supplements among Italian high school students. In total, 1232 students completed questionnaires measuring various psychological factors hypothesized to influence students' intention to use substances. Three months later, 762 of the students completed the same questionnaires a second time and also reported their use of substances during the time between assessments. Overall, the percentages of students using doping substances (2.1%) or supplements (14.4%) were consistent with values reported in the literature. Analysis of the data showed that adolescents' intention to use doping substances increased with stronger attitudes about doping, stronger beliefs that significant others would approve of their use, a stronger conviction that doping use can be justified, and a lowered capacity to resist situational pressure or personal desires. In turn, stronger intentions and moral disengagement contributed to a greater use of doping substances during the previous 3 months. Doping use was also correlated significantly to supplementation. In conclusion, our results provide novel information about some of the psychological processes possibly regulating adolescents' use of doping substances and supplements. The results also highlight possible areas for future study and intervention, focusing on the prevention of adolescents' substance use.  相似文献   

Numerical model application for the restoration of the Racconigi Royal Park (CN, Italy)     

Paolo Cavagnero  Roberto Revelli   《Journal of Cultural Heritage》2009,10(4):514-519

After years of neglect and an almost complete lack of maintenance, the Racconigi Royal Park was in an inevitable and widespread state of decay. This decay also involved the waterways that were designed in the nineteenth-century by Xavier Kurten (1811–1840). The seasonal lack of water and the agricultural needs of the farms around the Park made it necessary, during the planning stage of the restoration project, to consider the practicability and the effectiveness of some measures that were conceived to optimize the operation of the restored waterways, without altering the historical structure of the system. The realization of a hydraulic numerical model of the system, which is briefly illustrated in the first part of this case study, resulted to be the most suitable tool to study different possible solutions of the problem. The model simulations in fact helped the restorers put into effect the right remedies to favour the correct flow of the water, to make the whole historical system more efficient and to make its future maintenance easier.  相似文献

A low-cost method for estimating energy expenditure during soccer refereeing     

Luca Paolo Ardigò  Johnny Padulo  Andrea Zuliani  Carlo Capelli 《Journal of sports sciences》2015,33(17):1853-1858

This study aimed to apply a validated bioenergetics model of sprint running to recordings obtained from commercial basic high-sensitivity global positioning system receivers to estimate energy expenditure and physical activity variables during soccer refereeing. We studied five Italian fifth division referees during 20 official matches while carrying the receivers. By applying the model to the recorded speed and acceleration data, we calculated energy consumption during activity, mass-normalised total energy consumption, total distance, metabolically equivalent distance and their ratio over the entire match and the two halves. Main results were as follows: (match) energy consumption = 4729 ± 608 kJ, mass normalised total energy consumption = 74 ± 8 kJ · kg^?1, total distance = 13,112 ± 1225 m, metabolically equivalent distance = 13,788 ± 1151 m and metabolically equivalent/total distance = 1.05 ± 0.05. By using a very low-cost device, it is possible to estimate the energy expenditure of soccer refereeing. The provided predicting mass-normalised total energy consumption versus total distance equation can supply information about soccer refereeing energy demand.  相似文献   

The influence of dovetailed cross beams on the dimensional stability of a panel painting from the Middle Ages     

Ottaviano Allegretti  Marco Fioravanti  Paolo Dionisi-Vici  Luca Uzielli 《文物保护研究》2014,59(4):233-240

This paper describes experiments carried out to determine the influence of dovetailed cross beams on the dimensional stability of a panel painting from the Middle Ages. Besides a serious cup (transverse distortion), the panel featured an unusual longitudinal distortion, a bow, mostly originating from bending in the proximity of the middle cross beam. Because of its localized occurrence, bending appeared to be caused by the crossbeam somehow pushing on the walls of its channel. Thanks to the cooperation offered by the curator and the restorer, some non-damaging tests were performed to measure the distortions of the panel, with and without the cross beams, after conditioning it in different climates. Processing and analysis of the measurement results demonstrated that the bow of the panel increases as the wood moisture content decreases. This led to the conclusion that the bow is actually produced by forces exerted by the cross beam along the panel's length, according to a mechanism named thrust transformation. By this mechanism the cross beam partly transforms the panel's tendency towards cupping, into a bow distortion.  相似文献   

Students' transition into higher education: The role of self-efficacy,regulation strategies,and academic achievements     

Shanyan Lin  Sofia Mastrokoukou  Claudio Longobardi  Paolo Bozzato  Francesca Giovanna Maria Gastaldi  Martina Berchiatti 《Higher Education Quarterly》2023,77(1):121-137

Transition into higher education (HE) has received increased interest in recent years, since it represents a challenging period for students. The aim of this study was to further understand the associations between self-efficacy, academic achievements, and regulation in first-year university students during their transition into HE. The convenience sample consisted of 374 first-year university students (230 females, 61.5%), aged from 18 to 33 (M = 19.86, SD = 1.51) and recruited from an Italian university. Self-efficacy was assessed using the Motivated Strategies for Learning Questionnaire; regulation strategies were assessed with the Inventory of Learning Patterns of Students; and a self-reported grade point average was taken as an indicator of each student's academic performance. Result shows that students' self-efficacy was positively associated with self-regulation and negatively associated with a lack of regulation. Students with higher self-efficacy and self-regulation strategies had better academic performance. Female students performed better in academic activities and adopted more external regulation strategies. The findings represent an opportunity for university institutions to consider the interventions they provide to first-year students in order to facilitate the successful transition from secondary school; they also provide researchers with further knowledge about the effect of self-efficacy, and regulation strategies on students' adjustment to HE.  相似文献   

Passengers information in public transport and privacy: Can anonymous tickets prevent tracking?     

Gildas Avoine  Luca Calderoni  Jonathan Delvaux  Dario Maio  Paolo Palmieri 《International Journal of Information Management》2014

Modern public transportation companies often record large amounts of information. Privacy can be safeguarded by discarding nominal tickets, or introducing anonymization techniques. But is anonymity at all possible when everything is recorded? In this paper we discuss travel information management in the public transport scenario and we present a revealing case study (relative to the city of Cesena, Italy), showing that even anonymous 10-ride bus tickets may betray a user's privacy expectations. We also propose a number of recommendations for the design and management of public transport information systems, aimed at preserving the users’ privacy, while retaining the useful analysis features enabled by the e-ticketing technology.  相似文献
