This paper aims to extend understanding of the business and societal impact of academic research. From a business school perspective, it has taken stock of the role of academic research and relevance in business and society. The proposed conceptual framework highlights the forces influencing the pursuit of academic rigour and relevance in scholarly outputs. A theoretical model for measuring the societal impact of academic journal articles—the Academic Rigour and Relevance Index (AR2I)—was developed. This index comprises six key parameters, which are assessed by three stakeholder groups connected with academic research into business issues, these groups being: business practitioners, society and academics. The behaviour of the AR2I model was evaluated using the Monte Carlo simulation model. Taking into account the relationships between the standard deviations and the differences of classification between articles with different levels of rigour and relevance, it is demonstrated that the AR2I model is an effective tool. 相似文献

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

ABSTRACTIn 1974, the Brazilian sports official João Havelange was elected FIFA’s president in a two-round election, defeating the incumbent Stanley Rous. The upset, often attributed to a successful alliance with Asia, the Middle East and Africa, what at the time was referred to as the Third World – surprised observers everywhere. Here, the election can be analysed as a historically relevant event of social significance. It can be thought of as a political window by means of which the international dynamic of a specific moment in the Cold War can be perceived, especially the limitations and potentialities of the agency available to periphery countries at that time. In this article, I intend to discuss the narratives that forged the history of FIFA, which take this political ‘event’ as a key in the institution’s own historical transformation. The sources analysed will be mainly FIFA official histories, such as the FIFA News, FIFA historical books and movies about the history of FIFA. 相似文献

In many important application domains, such as text categorization, scene classification, biomolecular analysis and medical diagnosis, examples are naturally associated with more than one class label, giving rise to multi-label classification problems. This fact has led, in recent years, to a substantial amount of research in multi-label classification. In order to evaluate and compare multi-label classifiers, researchers have adapted evaluation measures from the single-label paradigm, like Precision and Recall; and also have developed many different measures specifically for the multi-label paradigm, like Hamming Loss and Subset Accuracy. However, these evaluation measures have been used arbitrarily in multi-label classification experiments, without an objective analysis of correlation or bias. This can lead to misleading conclusions, as the experimental results may appear to favor a specific behavior depending on the subset of measures chosen. Also, as different papers in the area currently employ distinct subsets of measures, it is difficult to compare results across papers. In this work, we provide a thorough analysis of multi-label evaluation measures, and we give concrete suggestions for researchers to make an informed decision when choosing evaluation measures for multi-label classification. 相似文献

ABSTRACTThe aims of this study were to perform the cross-cultural adaptation of the Borg Rating of Perceived Exertion (RPE) 6–20 Scale to Brazilian Portuguese language and to start testing its validity and reliability. After performing the cross-cultural adaptation of the Scale, concurrent and discriminative validity, and reliability were determined on a treadmill in young (18–30 years) and older adult women (60–75 years). Considering young and older adult women, RPE presented high and moderate positive correlation with heart rate and high and low positive correlation with oxygen consumption, respectively. Older adult women presented RPE (11 ± 2) significantly higher than young ones (8 ± 1) exercising at the same absolute intensity. Intraclass coefficient correlation was excellent for RPE to young and older adult women. The Scale presented concurrent validity only to young adult women, whereas it presented discriminative validity between such groups of women. Moreover, the scale is reliable to young and older adult women. 相似文献

We investigated whether low-level laser therapy (LLLT) prior to or post resistance exercise could attenuate muscle damage and inflammation. Female Wistar rats were assigned to non-LLLT or LLLT groups. An 830-nm DMC Laser Photon III was used to irradiate their hind legs with 2J, 4J, and 8J doses. Irradiations were performed prior to or post (4J) resistance exercise bouts. Resistance exercise consisted of four maximum load climbs. The load work during a resistance exercise bout was similar between Control (non-LLLT, 225 ± 10 g), 2J (215 ± 8 g), 4J (210 ± 9 g), and 8J (226 ± 9 g) groups. Prior LLLT did not induce climbing performance improvement, but exposure to 4J irradiation resulted in lower blood lactate levels post-exercise. The 4J dose decreased creatine kinase and lactic dehydrogenase levels post-exercise regardless of the time of application. Moreover, 4-J irradiation exposure significantly attenuated tumor necrosis factor alpha, interleukin-6, interleukin-1β, cytokine-induced neutrophil chemoattractant-1, and monocyte chemoattractant protein-1. There was minor macrophage muscle infiltration in 4J-exposed rats. These data indicate that LLLT prior to or post resistance exercise can reduce muscle damage and inflammation, resulting in muscle recovery improvement. We attempted to determine an ideal LLLT dose for suitable results, wherein 4J irradiation exposure showed a significant protective role. 相似文献

Two important problems have been observed fairly frequently among information technology (IT) professionals, namely turn-over – where the IT professional moves to another company but still remains in the IT sector – and turn-away, in which the IT professional abandons the area in order to occupy a position in a different area, either in the same company or in another, sometimes assuming a managerial function. Few research papers were found with respect to the latter phenomenon. Based on that, the main thrust of this work is to understand how and why IT professionals in Brazil abandon their area, identifying typical characteristics in their career transition. Thus, from a literature review about career development and the analysis of the data collected, eight research hypotheses were developed in order to be analyzed by the researchers. A multiple case study method with several units of analysis was applied in two large companies in Brazil. In-depth interviews were conducted with IT professionals who had migrated to other areas within their organizations, they being considered the unit of analysis. The results accrued from this research reveal that IT professionals in Brazil need to have more growth opportunities than either their companies have been able to offer them or it is possible to offer within the technical arena. 相似文献

ABSTRACT— In this article, we discuss school schedules and their implications in the context of chronobiological contemporary knowledge, arguing for the need to reconsider time planning in the school setting. We present anecdotal observations regarding chronobiological challenges imposed by the school system throughout different ages and discuss the effects of these schedules in terms of sleepiness and its deleterious consequences on learning, memory, and attention. Different settings (including urban vs. rural habitats) influence timing, which also depends on self-selected sleep schedules. Finally, we criticize the traditional view of a necessary strict stability of sleep–wake habits. 相似文献

Background: Under the view of dynamical system theory, expertise in sports emerges from the interaction of multiple constraints. At an individual level, important interactions amongst constraints could include the relationships that evolve between one's family, playmates/coaches, and specific training activities. Or more broadly, other environmental constraints can be the strong socio-cultural-historical contexts that influence expertise development in sports around the world, such as rugby (e.g. New Zealand) and football (e.g. Brazil). An increasing number of studies have demonstrated the influence of environmental constraints on the development of sport expertise. Whilst making important contributions to knowledge, such studies have been limited in scope and fail to consider in depth how informal and even aversive learning environment constraints affect skills development.
Objective: The objective of this paper is to outline a new contextualised approach to studying socio-cultural constraints on individuals, proposing an interpretive, multi-method approach to holistically investigate the interacting constraints on an athlete's development pathway.
Aims: We explain a rationale for adopting an interpretive research paradigm (in contrast to traditional positivist approaches) for exploring socio-cultural constraints. The epistemological and methodological assumptions of Bronfenbrenner's Bioecological Model of Human Development are proposed as an underpinning framework for data collection and organisation of material. We advocate for ethnographic strategies of inquiry, followed by a discussion of potential methods for generating and analysing data: contextual analysis, participant-observation, and open-ended interviews. Finally, we discuss evaluation criteria for this contextualised approach viewed from a coherence theory of truth.
Purpose: This position statement seeks to: (1) promote methodological possibilities to investigate the effect of socio cultural constraints on expertise acquisition in sport and (2) offer significant new theoretical and epistemological insights from the constraints-led approach to expertise and to integrate some of the interdisciplinary differences that exist in the body of sciences.
Final thoughts: Our tentative contribution to the development of the proposed contextualised skill acquisition research framework is to build bridges across the methodological boundaries between sociology and motor learning in the first instance, rather than offering a unifying approach for the whole field. We hope that this position statement will provide a foundation for future related empirical papers and to stimulate other researchers to consider the framework for their own investigations of motor learning in the field. 相似文献
