From the late 1990s, corrupt practices in Greek football have been considered to pose a serious threat to the integrity of the sport, with a number of schemes and measures being introduced as a response. The aim of this article is to show why corruption in Greek football is inevitable by offering a detailed account of three football-related corrupt practices and highlighting their contextual parameters, as well as juxtaposing them against the set of measures that have been implemented. By placing corruption in football in the wider landscape of the country and of global football, and examining the political, structural and economic factors that contribute to the overall managerial and financial implications of corruption, we present the reader with the new norm which, in reality, makes corruption the ‘only game in town’. 相似文献

This paper explores new data sources on multilateral trade in films among EU countries and with the USA in offline cinema and in online video-on-demand distribution. We observe variations in trade patterns across countries and films and explore how they affect cultural diversity. We find that the EU film market is highly fragmented and cross-border film availability in cinema is low. We explore different aspects of the cultural discount hypothesis by means of a standard Helpman and Krugman (Market structure and foreign trade. Increasing returns, imperfect competition, and the international economy, MIT Press, Cambridge, 1985) trade model with economies of scale and a two-stage Heckman (Econometrica 47(1):153–161, 1979) estimation procedure. Our results show that cultural distance, success in the home market and the size of the film budget influence trade of films between countries. US films have a lower propensity to get into export markets, relative to their success in the home market. Consumer demand for imported films is relatively smaller in large EU economies, except for films imported from the USA that are only marginally affected. We also show that trade patterns in online film distribution are not fundamentally different. As online distribution occurs downstream from theatrical release, online distributors can benefit from cinema market experience to make a better selection of films. This results in a lower impact of domestic market shares on online trade patterns. 相似文献

通过文献资料调研、问卷调查、数理统计和逻辑分析等方法,对残疾人奥林匹克学校日活动的参与者对待残疾人的态度前后进行对比.对捷克一所本地学校和一所国际学校的残疾人奥林匹克学校日的参与者进行问卷调查,针对不同文化、语言背景的学生,问卷采用了捷克文和英文两个版本,结果发现,国际学校和本地学校参与者对待残疾人的一般态度发生了积极的变化,而对因为残疾人参与体育而改变规则的态度发生了消极的变化,这说明,残疾人奥林匹克学校日能对来自不同文化、语言背景下的参与者对残疾人态度产生积极的影响,然而,由于活动选取不当等原因也可能造成消极影响.因此,在组织残疾人奥林匹克学校教育活动时,必须要考虑参与者的特点,更为科学地选取活动项目,保证教育效果.我国应利用北京残奥会教育奠定的良好基础,结合实际情况,在某些学校尝试组织类似于残疾人奥林匹克学校日的教育活动并进行可行性研究和效果评价,为今后的大范围推广做好准备. 相似文献

The aims of our study were to compare the dominant (DOM) and non-dominant (NDOM) shoulders of high-level volleyball athletes and identify possible associations of shoulder adaptations with spike speed (SS) and shoulder pathology. A total of 22 male volleyball players from two teams participating in the first division of the Cypriot championship underwent clinical shoulder tests and simple measurements around their shoulder girdle joints bilaterally. SS was measured with the use of a sports speed radar. Compared with the NDOM side, the DOM scapula was more lateralised, the DOM dorsal capsule demonstrated greater laxity, the DOM dorsal muscles stretching ability was compromised, and the DOM pectoralis muscle was more lengthened. Players with present or past DOM shoulder pain demonstrated greater laxity in their DOM dorsal capsule, tightening of their DOM inferior capsule, and lower SS compared with those without shoulder pain. Dorsal capsule measurements bilaterally were significant predictors of SS. None of the shoulder measurements was associated with team roles or infraspinatus atrophy, while scapular lateralisation was more pronounced with increasing years of experience, and scapular antetilting was greater with increasing age. Adaptations of the DOM shoulder may be linked to pathology and performance. We describe simple shoulder measurements that may have the potential to predict chronic shoulder injury and become part of injury prevention programmes. Detailed biomechanical and large prospective studies are warranted to assess the validity of our findings and reach more definitive conclusions. 相似文献

The study assessed cognitive and academic performance of children demonstrating teacher-rated ADHD-related symptoms (Inattention [IA] and/or Hyperactivity/Impulsivity [H/I]) in a representative sample of, largely untreated, Greek elementary school students (N?=?923). A battery of tests assessing short-term memory (STM), sustained attention, executive functions (EFs), reading and math skills were administered. Significant deficits in EFs and STM were restricted to the groups of students displaying inattention symptoms and were only marginally elevated among students showing hyperactivity/impulsivity symptoms alone, in comparison to their non-symptomatic peers. A similar pattern of group differences was observed on tests assessing word- and text-level reading skills. Impaired performance on sustained attention tasks was less evident. Among students who manifested inattention symptoms, those who also showed impaired reading skills presented more severe EFs deficits than typically achieving students. Results demonstrated a close link between EFs, other than inhibition and set-shifting, everyday symptoms of inattention, and achievement in math and word-level reading skills. 相似文献

In this research we investigate whether the categorisation of physical quantities into intensive and extensive, according to scientific knowledge, is perceivable and understood by pupils aged 12–15 years. For this purpose we administered written questionnaires to 300 pupils, comprising four tasks for each intensive quantity: density and pressure. The tasks investigate whether pupils realise that intensive quantities do not depend on the amount of the system they refer to and the factors affecting pupils' reasoning and their consistency when studying phenomena involving fluids at rest or in transition. The analysis of responses led us to identify three models of consistent pupils' reasoning. It was also observed that a significant percentage of the pupils provide inconsistent answers, that is, they change their reasoning across tasks and use alternatives to scientific reasoning, influenced by phenomenological features of the tasks. According to our results we propose a number of recommendations, such as the introduction of intermediate teaching/learning steps to be followed as well as suitable experiments to be used towards the acquisition of the scientific model for density and pressure. 相似文献

This study explores children's attitudes toward individuals with special needs in Greece and in the United States. A total of 196 kindergarten‐age children participated in the study. Children's attitudes were examined using the Acceptance Scale for Kindergartners‐Revised (ASK‐R) and were further explored with the use of an open‐ended interview. In addition, the Inventory of Disability Representation (IDR) was used to collect information about how individuals with special needs are represented in school and classroom environments through books, displays, materials and curriculum. The results indicated that children in Greece and the United States were accepting of individuals with special needs. Also, children attending inclusive kindergartens held more positive attitudes when compared with children attending non‐inclusive kindergartens. Results from the interviews provided further information that contributes to the understanding of children's perceptions of people with special needs and the reasons why children become more or less favourably disposed towards individuals with special needs. Finally, IDR results indicated that the classrooms in Greece had low representations of individuals with special needs compared with US classrooms, which had moderate and high representations of individuals with disabilities in the classroom and school environments. 相似文献

In Greece, the development of the teaching of Information Technology (IT) in schools has been greatly influenced by the rapid development of technology, making IT literacy a priority for all individuals. Consequently, the teaching of algorithms and programming, with the ulterior motive of teaching modeling as well as problem solving, has been greatly limited in Secondary Education. However, we strongly believe that algorithms and programming constitute an important intellectual tool and should be included in basic education. In any case, both the research literature findings, as well as, our own experience confirm the fact that novice programmers come up against many mental obstacles in their attempts to understand the functioning of programs or the construction of algorithms. In order to deal with these difficulties and successfully teach the elementary concepts of algorithms and programming, we have developed didactic scenarios, which are based on specially designed educational software. In conjunction with this, we are attempting to develop a program for the systematic training of those students who will become IT teachers in Secondary or Primary Education. The most significant findings of our research are summarized as follows: (a) The development of educational software and its experimental use in the teaching process allow us to formulate several general rules related to the specific didactic characteristics, which these environments should include. (b) Educational software is effective only when it is incorporated within the framework of the didactic scenarios that the teacher organizes and which are supported by the software. (c) Teachers do not spontaneously use educational software in the context of this rationale. Therefore, specific training is required so that they adopt and use such software in didactic scenarios. 相似文献
