Long-run benefits from universal high-quality preschooling

This paper investigates the role of preschool quality for children's school performance at the end of primary school. We construct five structural quality indicators based on unique Danish administrative register data. 30,444 children finishing primary school's 9th grade in 2008 and who attended a formal preschool institution in 1998 are used in the analyses. OLS analyses show that three out of five quality indicators, a higher staff-per-child ratio, a higher share of male staff, and a higher share of staff with formal preschool teacher training are associated with significant improvements in children's test results in Danish. Boys benefit more from preschool quality than girls. Ethnic minority children benefit from higher staff stability.     

The influence of university departments on the evolution of entrepreneurial competencies in spin-off ventures

The influence of the university department upon spin-off venture evolution is complex and dynamic. We examine how the university department context influences the spin-off process from the perspectives of both the spin-off venture and the department. By comparing the development of entrepreneurial competencies within spin-offs based in different departments at the same universities we observed significant differences in early venture performance. Small differences in initial departmental support from management and senior academics for gaining commercial experience and spending time exploring the commercial opportunity were seen to have a major impact upon the subsequent spin-off development path. Supported ventures gained momentum as the department helped develop entrepreneurial competencies and influenced how these competencies were developed from external actors outside the department. By contrast, a lack of departmental support for entrepreneurship severely constrained the evolution of spin-offs regardless of university level policies and practices. This emphasizes the need for a shift in focus from the well-studied university level to the relatively neglected department level to help explain institutional differences in university spin-off activity.     

The effect of plot explicit,educational explicit,and implicit inference information and coviewing on children's internal and external cognitive processing

Parental coviewing – the act of being present when a child is watching television – can influence the child’s cognitive processing and emotional reactions. This study investigated the role coviewing has on the child’s cognitive processing – which is evidenced by the phasic psychophysiological orienting response to three types of information: plot explicit, educational explicit, and implicit inference. An experiment was conducted that measured the heart rate of children (N?=?88; mean age?=?9.12 years) while watching messages either with or without a parent present in the room. It was predicted, and found, that coviewing leads to greater resource allocation to encoding the message – as indicated by phasic cardiac deceleration, and that information that required internal processing, such as plot explicit or implicit inferential content, leads to greater resources allocated to internal processing – as indicated by phasic cardiac acceleration. Implications for parental mediation strategies and educational television programming are given.     

‘Alternative’ universities revisited: A study of the distinctiveness of universities established in the spirit of 1968

Abstract

In the late 60s and early 70s, several universities were set up in various European countries with the intention of providing an alternative to established institutions of higher education. The new universities were expected, amongst other things, to experiment with new forms of leadership and management internally, give teaching and learning higher priority, and to be regional relevant institutions for the area in which they were located. The paper analyses to what extent three such university establishments: Aalborg University in Denmark, Maastricht University in the Netherlands and Troms?University in Norway have managed to maintain and develop their alternative profile during the last thirty years. The study suggests that even though the universities in some areas have adapted to environmental pressure, they have managed to keep their profile as innovative and alternative.     

The importance of being elastic: Deflection of a badminton racket during a stroke

Abstract

The deflection profiles of a badminton racket during strokes performed by elite and world-class badminton players were recorded by strain gauges and subsequently analysed to determine the role of shaft stiffness in racket performance. Deflection behaviour was consistent in all strokes across all players, suggesting a controlled use of racket elasticity. In addition, all impacts occurred within 100 ms of each other, a duration in which deflection velocity provides an increase in racket velocity, indicating that the players were able to use racket elasticity to their advantage. Since deflection behaviour is a product of the racket–player interaction, further work is required to determine the effects of different racket properties and player techniques on the elastic response of rackets during strokes.     

Electromyographic Patterns During Level and Inclined Treadmill Running and Their Relationship to Step Cycle Measures

Abstract

Eight highly skilled male distance runners were filmed while running on level and inclined treadmills. During the filming sequence, EMG measurements were collected on vastus medialis (VM) and semimembranosus (SM) of the right thigh. The initiation and duration of electrical activity of the two muscles was extracted from the recordings relative to the step cycle events. Analysis of covariance for repeated measures was utilized as a statistical treatment to examine the effect of treadmill grade (– 10%, 0%, and + 10%) upon step cycle and EMG data. Results indicate that treadmill grade had a significant effect on the relative duration of both stance and swing phases of the running step cycle and total step cycle duration. Total step cycle time and relative swing phase duration decreased as the treadmill grade was changed from a negative grade to a zero grade to a positive grade while the duration of the stance phase increased. EMG measures indicated decreases in relative duration of SM activity during the stance phase progressing from negative grade to zero grade to positive grade while an increase in SM activity was noted during the swing phase. VM activity during stance was longest in negative grade running, decreased in level grade running, and increased again in positive grade running.     

Measuring Children's Age Stereotyping Using a Modified Piagetian Conservation Task

We examined five-year-old-children's age stereotyping using a modified Piagetian conservation task. Children were asked if two lines of objects were the “same” after one line had been made longer (transformed). A conversational account posits that children's answers reflect assumptions about the asker's motivation for the question (Schwarz, 1996 Schwarz , N. ( 1996 ). Cognition and communication: Judgmental biases, research methods, and the logic of conversation . Mahwah , NJ : Lawrence Erlbaum . [Google Scholar]). We reasoned that when asked by a young adult (puppet Experiment 1, experimenter Experiment 2) children would assume the question is to ascertain if they have noted a perceptual change and would provide answers focused on the change (length). If older adults are assumed to be in decline because of negative age stereotyping, however, children may assume an older adult (puppet, experimenter) is seeking clarification about line equality and would, therefore, give responses focused on the similarity of the lines (number). The expectation that a focus on length or number should differ across puppet/experimenter conditions was supported in both experiments and provides behavioral evidence for children's old age stereotyping.
