Checking both sides of an equation to make sure the units are right is something we tend to do as a matter of course (or should!). But as this article will try and illustrate, there is more to this routine procedure than meets the eye. 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

The being together intervention intends to raise teacher capacity in Norwegian Early Childhood Education and Care (ECEC) institutions and promote social and emotional development in preschoolers by implementing an authoritative (warm and predictable) adult style in the institution. An authoritative adult balances between building up high quality interactions with children, while at the same time having a predictable structure with clear norms and social expectations in the learning environment. The purpose of this study was to investigate what helped the ECEC institutions to successfully implement the program principles and core components, and what were the challenges. The staff groups of seven Norwegian ECEC institutions in different municipalities who took part in the innovation were interviewed at the beginning and before the end of the first year of implementation. Data analysis identified five success criteria in the implementation process; strong commitment to the authoritative adult style, strong focus on the implementation process, advanced support systems, highly involved leaders, and a collective orientation. These elements resulted in a shared vision and an academically grounded practice in the ECEC institutions. Staff members without formal professional training and a lack of written documentation in the ECEC institutions should be given more consideration in further improvement of the capacity building. 相似文献

In China, educational publishing is devoted to publishing mainly textbooks and teaching materials. For a long time, education
publishing has dominated others in China’s publishing industry. However, after entering the new century, especially in the
last 2 years, there has been the impact of changes in the College-Entrance Examination, the Invitation to Bid for Compilation
and Publication of Textbooks, government procurement and Scientific and Technological Advancement for supplementary books.
Therefore, publishing for education has been losing its previous major role and dominance. For making a leap forward and breakthrough
in educational publication, we must open up a new train of thought for the development of educational publishing, we need
three distinct transformations: first, change in publishing mode from extensive to intensive growth. Second, transformation
from variety-scale to market-scale expansion. Third, transformation from being just a provider of content to one providing
both content and services. 相似文献
