ABSTRACT The recruitment of athletes with limited resources is a global problem in professional sports. In US Major League Baseball, the experience of the Oakland Athletics’ general manager in the last decade turned his “Moneyball” model into a synonym of quantitative analysis in the transfer market of baseball players. His strategy focused on hiring players with outstanding technical skills but relatively low market value. This study adapted this model to the framework of a multiple criteria decision aid (MCDA), by selecting undervalued players who have complementary abilities. The novelty here refers to the joint use of four algorithms explored by the composition of probabilistic preferences (CPP) (i.e., ranking, classification, dynamic evaluation and regularity analysis) and their application to soccer player performance evaluation. The new model analysed the recent transfer of a left-back soccer player to Europe. The results indicated 12 opportunities for better investment, among 32 left and right-back players considered. Two years later, the value of the same player was considerably lower. He played only five matches in the 2018–2019 season, without scoring or providing any assists. On the other hand, the players better classified by the CPP-MB model presented higher performances and market values. 相似文献

This article is based on research undertaken as part of a study of sustainable school design in Thailand. Since school design solutions are inevitably affected by educational theory and practice, in the search for appropriate building solutions, it has been necessary to review Thai educational theories and practices that relate to the sustainability approach. Recently, there have been several attempts at the international level to respond to sustainability concepts and practices in both educational and architectural fields. These have included changes to the physical building through the introduction of techniques like passive solar cooling, and curriculum changes such as the use of native plants in the school grounds for science teaching. In Thailand, sustainable practices in both fields appear to be in their infancy. This article aims to explore one current Thai educational practice that presents the possibility of responding to sustainability concepts via culturally sensitive education. The practice is based on the three Buddhist principles of learning: sila sikkha (moral conduct); samadhi sikka (mind training); and panna sikkha (wisdom development). In this holistic approach, the principles are practised simultaneously and can be applied to many dimensions, including personal, family, school and communal levels, to cultivate responsive sustainable living practices for the learners. Because the majority of Thai people are Buddhists, this approach may be an alternative way of developing sustainable education in Thailand. It also presents a way to apply local knowledge to promote sustainable ways of living in particular contexts. This may be the first step in the development of sustainable school design in Thailand and could become an integrated part of the country's sustainable systems. 相似文献

This paper is based on a PhD study (Lwoga, 2009) that sought to assess the application of knowledge management (KM) approaches in managing indigenous knowledge (IK) for sustainable agricultural practices in developing countries, with a specific focus on Tanzania. This study used a mixed-research method which was conducted in six districts of Tanzania. Non-participant observation, semi-structured interviews, and focus groups were used to collect primary data from small-scale farmers in the selected districts. A total of 181 farmers participated in the semi-structured interviews, where the respondents ranged between 27 and 37 per district. Twelve focus group discussions were conducted in the selected districts. The study revealed that IK was acquired and shared within a small, weak and spontaneous network, and thus knowledge loss was prevalent in the surveyed communities. There were distinct variations in the acquisition of agricultural IK both in different locations and between genders. Information and communication technologies (ICT), culture, trust, and status influenced the sharing and distribution of IK in the surveyed communities. The research findings showed that KM models can be used to manage and integrate IK with other knowledge systems, taking the differences into account (for example, gender, location, culture, infrastructure). The paper concludes with recommendations for the application of KM approaches for the management of IK and its integration with other knowledge systems for agricultural development in developing countries, including Tanzania. 相似文献

We aimed to estimate metabolic bone profile in a large cohort of healthy, adult Indian population to generate reference standards of serum calcium, phosphate and alkaline phosphatase (ALP), 25 (OH) Vitamin D and iPTH, and also to find out the prevalence of Vitamin D deficiency in healthy population. Apparently healthy people in the age group of 20–80 years, residing in the union territory of Chandigarh were chosen. Fasting samples for serum calcium, phosphate, albumin, alkaline phosphatase (ALP), 25 (OH) D and iPTH were collected and were processed on the same day. We recruited 930 healthy subjects from different subsectors of Chandigarh. Final analysis was done for 915 subjects. Out of this, 530 (58%) were women and 385 (42%) were men. The study participants were divided into two groups, less than and more than 50 years for the men and pre and post-menopausal for the women. The serum calcium, phosphate, ALP and iPTH were significantly higher in the post-menopausal women compared to the pre-menopausal women. The median plasma 25 (OH) D in men and women was 12.5 ng/mL and 14.3 ng/mL, respectively. 25 (OH) D deficiency was seen in 65.4% of individuals. 25 (OH) D levels co-related negatively with iPTH levels (r = − 0.4, p < 0.0001), and showed an increasing trend with age. We have thus presented metabolic bone profile of healthy, adult north Indian population. These reference values can be used for diagnosis and monitoring of various MBDs. Vitamin D deficiency is still rampant in our population in spite of increasing awareness. 相似文献

Youth councils are examined as spaces of citizenship education where young people are educated as political subjects. At a time of political and economic instability data were collected in a Catalan city through tests and focus groups involving 112 students, three teachers and two youth council managers during one academic year. Students’ political trust decreased and their cynicism towards politics increased; there were no changes in students’ anticipated future participation. The article avoids drawing simplistic causal links between students’ involvement in a council and the expression of their views. The participants also discuss the councils as performance sites. It is speculated whether, in students’ views, this metaphor of performance applies not only to the councils but to the wider political context in which they live. It is argued that youth councils are, in some ways, potentially valuable for promoting participation and recommendations are made in light of the findings. 相似文献

We discuss the ways in which English and Catalan students perceive themselves as members of communities and as citizens and the role of schools in these perceptions. Questionnaire and interview data were collected and analysed from 583 secondary school students in a total of 9 schools that were known for their commitment to citizenship education in England and Catalonia. The research took place when issues of national and other identities were prominently discussed in the media and elsewhere and when significant changes were being introduced in both locations regarding citizenship education as a specific curriculum subject and also in the wider context of education and schooling. Our results suggest that while the English students in our sample understand citizenship in terms of a subjective identification, our Catalan students perceive citizenship as a legal and externally assigned status. We did not intend to obtain nationally representative samples but rather to gain in-depth knowledge of the data and to discuss the implications of these results for the differing purposes of citizenship education. We make recommendations for how school-based citizenship education may contribute to current challenges related to citizenship and identities. 相似文献

ABSTRACTThis self-study, based on research, conducted over five years, focuses on my leadership role employing an inclusion model of education in a school in Iceland serving students from ages 6 to 16. In this article, we examine how Edda’s practice helped support inclusion for the students, their families, and the teachers who engage with them. This multilayered self-study research project included feedback and insights from others in order to inform my understanding of my practice within the context of inclusion. Findings reveal Edda’s focus on the discourse of diagnosis as a dominant structural issue within her practice. The resulting themes on perceptions of inclusion, coordination of support, deployment of people, and collaboration across different entities have informed my understanding about my practice and my perspective on the meaning of a support system within inclusive education and improved student performance. 相似文献

Coronavirus disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a global health problem, India being the second most affected country. The kinetics of antibody response to SARS-CoV-2 in Indian population is not studied yet. To understand serological response in relation to age, gender, time period and severity of disease, Roche Elecsys anti-SARS-CoV-2 test was used which analysed both IgM and IgG. One hundred and three COVID-19 patients were enrolled. Seropositivity was seen in 64% of patients, with 33% at ≤ 7 days, 62% between 8 and 15 days and 81% at ≥ 16 days from the time of admission. Men (65%) showed higher antibody response than women (59%), whereas no difference was observed in seropositivity with respect to age of the patients. Dynamics of antibody responses revealed individual variations. Patients in ICU had higher antibody reactivity with 67% positivity as compared to 60% positivity in non-ICU patients. Kinetics of antibody response during COVID-19 disease varied in relation to gender, age, time period and severity and these factors might play an important role in treatment and control of COVID-19. 相似文献

ABSTRACTProponents often claim that bidding for and hosting sport events have an overall capacity to generate a variety of benefits for cities and regions. Despite limited empirical evidence to support these assertions, cities continue to vie for hosting rights. In an effort to maximise the benefits of hosting, host cities have adopted a strategic approach to event planning and management referred to as event leveraging. A critical concern raised in the leveraging literature is how event-related strategies fit with the broader tourism development agenda of cities and regions, and how they are implemented. This paper uses Urban Regime Theory (URT) to understand how and why cities seek to host events, and how the process of leveraging is undertaken to maximise the benefits of hosting. Viewing events and strategies in the context of regimes, highlights why some cities and regions have been successful in leveraging sport events for tourism gain over time and, importantly, why some have not. This paper synthesises the existing body of work on tourism-based sport event leveraging, identifies three ways academic research has explored leveraging, and uses regime theory as a lens to further our understanding of the leverage process in host cities. 相似文献
