Science and technology management: Designing an undergraduate course

This research focusses on the role of science educators in preparing technically educated graduates for their careers. A comparison was made between the skills and abilities in science and technology students desired by industrial employers and whether New Zealand graduates exhibit these qualities. To address some of the management-based issues identified by the research, the design of a new Science and Technology Management course is outlined. Specializations: science and technology education, co-operative education, development of professional skills. Specializations: co-operative education programmes.     

Talented athletes and academic achievements: a comparison over 14 years

The purpose of this study was to gain insight into the academic achievements of 200 talented athletes in 1992/1993 and 200 in 2006/2007, aged 14–16 years. When compared with the national average, the athletes in 2006/2007 attended pre‐university classes more often (χ² = 57.001, p<.05). Of the 2006/2007 athletes, a higher percentage participated in pre‐university programs compared with that of athletes in 1992/1993 (χ² (1, n = 400) = 32.003, p<.05), whereas the national averages showed stability (χ² = .325, p>.05). Investigating self‐regulation appears relevant, as talented athletes may have developed a high sense of self‐regulation in sports, which may enable them to optimally profit from their self‐regulatory skills in their academics.     

Biodiversity for Beginners

Biodiversity is a difficult concept. It can be introduced to young children successfully, laying the foundations for further study in later years. This article describes one practical activity for 5‐ and 6‐year‐old children.     

Variability of inter-team distances associated with match events in elite-standard soccer

Abstract In soccer, critical match events like goal attempts can be preceded by periods of instability in the balance between the two teams' behaviours. Therefore, we determined periods of high variability in the distance between the teams' centroid positions longitudinally and laterally in an international-standard soccer match and evaluated corresponding match events. Position data were collected with AMISCO Pro?. Inter-team distance variability was calculated over a 3-s moving window. Out of the 242 match periods that exceeded the variability criterion, 51 were dead-ball situations. Match events identified through longitudinal inter-team distance primarily related to defending players moving forward-backward after a longitudinal pass. Match events identified through lateral inter-team distance mainly corresponded with defending players moving laterally following sideways passing. One of two goals and two of fourteen goal-attempts were preceded by a period of high variability. Together, periods of highly variable inter-team distance were associated with collective defensive actions and team reorganisation in dead-ball moments rather than goals or goal attempts. Inter-team dynamics quantified (mutual) reorganisation of the teams and marked teams' collective defensive ability to respond to attacking explorations.     

Comparison of 2D video and electrogoniometry measurements of knee flexion angle during a countermovement jump and landing task

Quantifying countermovement jump (CMJ) and landing knee flexion angle is important for performance and injury risk assessment. The purpose of the study was to compare electrogoniometer (El-Gon)- and video-derived CMJ and landing knee flexion angle. Twenty-two adults performed three CMJs while knee flexion angle was simultaneously assessed using an El-Gon and video. The average systematic offset (RMSE) of the El-Gon-derived knee flexion angle throughout the entire movement was 7.03°?±?2.69°. Excellent reliability was demonstrated by the El-Gon (ICCavg?=?0.92). Countermovement knee flexion angle, maximum landing knee flexion angle and flexion angle at maximum vertical ground reaction force were 12.0°, 10.9°, and 5.7° higher, respectively, when assessed using El-Gon (p?<?0.001), compared to video. Errors between instruments are likely due to El-Gon crosstalk, misalignment and/or axis determination. The El-Gon is a cost-effective and time-efficient alternative to video analysis for the assessment of knee flexion angle if the error is accounted for and the sensor is precisely attached.     

DNS白名单会阻碍IPv6的实施吗？

什么是DNS白名单？在当今的公共互联网上使用IPv4地址时,解析程序可以向权威的域名服务器查询并接收IPv4的地址A记录。当一位权威DNS的管理员为指定域添加IPv6地址AAAA记录时,它将像A记录和其他RR一样被解析程序查询和接收。
