A hedonic model of player wage determination from the Indian Premier League auction: Further evidence

A range of cross-sectional models are estimated with a view to establishing the factors that determine the valuation of professional athletes in a highly-specialised sport, with an application to cricket's Indian Premier League (IPL). We distinguish between personal characteristic and playing ability factors, and with respect to the former, between ability in different forms of the sport. We find a number of interpretable variables that have explanatory power over auction values, while decomposition according to batting and bowling specialisations produces very different results depending on the use of either Test or One-Day International (ODI) variables. There is also possible evidence of inefficient bidding, insomuch that overbidding was somewhat correlated with players with higher realised values.     

Reading research in Hungary

Much recent reading research in Hungary has focused on the formation of readers’attitudes and value judgements. This paper reports the results of a number of such studies, based on research with various groups, including library users, ‘killed-worker’ students, and children. A‘more books’programme has been found to be successful in developing a more discriminating approach to literature, but there is concern over national trends in reading. International studies have shown Hungarian students to be comparatively good at science but poor at reading. More books are being bought, and the proportion of women readers is increasing, but adults are spending less time on reading, and have a growing interest in non-fiction. The results of reading research in Hungary are not regarded as of purely theoretical interest. Such results are regularly used by librarians and by educational administrators.     

Journal ranking should depend on the level of aggregation

Journal ranking is becoming more important in assessing the quality of academic research. Several indices have been suggested for this purpose, typically on the basis of a citation graph between the journals. We follow an axiomatic approach and find an impossibility theorem: any self-consistent ranking method, which satisfies a natural monotonicity property, should depend on the level of aggregation. Our result presents a trade-off between two axiomatic properties and reveals a dilemma of aggregation.     

Soziale Disparit?ten und die ?ffnung des Sekundarschulsystems

Efforts to break the link between the school type attended and the qualification awarded are seen an important step in the modernization of Germany??s tracked secondary school system. However, it remains disputed whether these efforts have reduced social disparities or in fact increased them. This study examined the transition from lower secondary education in academic- and intermediate-track schools to upper secondary education in general and vocational gymnasium schools in the state of Baden-Württemberg. When indicators of parental social background and school-leaving qualifications were controlled, the opening of upper secondary education was found to be associated with a decrease in the social selectivity of upper secondary education for intermediate-track students. At the same time, for those intermediate-track students who were entitled to enter upper secondary education, social background had predictive effects on the transition decision; however, the overall size of these effects was low.

Self-Control in School-Age Children

Conflicts between immediately rewarding activities and more enduringly valued goals abound in the lives of school-age children. Such conflicts call upon children to exercise self-control, a competence that depends in part on the mastery of metacognitive, prospective strategies. The process model of self-control organizes these strategies into five families corresponding to sequential phases in the process by which undesired and desired impulses lose or gather force over time. Situation selection and situation modification strategies involve choosing or changing physical or social circumstances. Attentional deployment and cognitive change strategies involve altering whether and how objective features of the situation are mentally represented. Finally, response modulation strategies involve the direct suppression or enhancement of impulses. The process model of self-control predicts that strategies deployed earlier in the process of impulse generation and regulation generally will be more effective than those deployed later. Implications of this self-control perspective for school-age children are considered.     

The solution of compare problems among first-grade students

This study attempts to specify the relational calculi that young students elaborate for solving compare problems, which have been identified as being among the most difficult of the addition problems. Based on an integration of hypotheses and models from research attempting to account for problem-solving activity on these problems, an a priori analysis makes explicit the relational calculi capable of leading to the solution of six compare problems. This analysis provides a foundation for an analysis of protocols, which were collected from 25 first-grade students solving and reformulating compare problems. The results highlight the dynamic character of the structuring and arithmetizing processes in setting up the relationships within a problem. Thus, the numerical calculi employed are interpreted as a function of the structure of the problem and, in turn, the situation described by the problem derives its meaning from a knowledge of the arithmetic operations activated by the numerical calculi.
