Congenitally deaf children's care trajectories in the context of universal neonatal hearing screening: a qualitative study of the parental experiences     

Hardonk S  Desnerck G  Loots G  Van Hove G  Van Kerschaver E  Sigurjónsdóttir HB  Vanroelen C  Louckx F 《Journal of deaf studies and deaf education》2011,16(3):305-324

The objective of this study is to examine the early care trajectories of congenitally deaf children from a parental perspective, starting with universal neonatal hearing screenings. The analysis using a three-dimensional care trajectory concept is aimed at developing a basic typology of postscreening care trajectories. Children with severe/profound hearing loss, registered in the Flanders' (Belgium) universal neonatal hearing screening program, born between 1999 and 2001. Thematic content analysis of qualitative data collected retrospectively from participant's parents. Two basic types of care trajectories emerged; based on differences in care-use in the phase of further diagnosis and related parental experiences. Subtypes resulted from events related to cochlear implantation. Five trajectory phases were identified: screening, further diagnosis, care and technology, cochlear implantation, and reduction of care and were characterized by specific parental experiences such as confusion, disbelief, disappointment, and uncertainty. Those experiences relate to care professionals' acts and communication and the child's functional evolution. Early care interventions could benefit from coordinated transition between phases, parent support throughout the care trajectory, and a broad approach to deafness in professionals' communication.  相似文献   

The effect of equipment scaling on children’s sport performance: the case for tennis     

Ewout Timmerman  Joel De Water  Kim Kachel  Machar Reid  Damian Farrow  Geert Savelsbergh 《Journal of sports sciences》2015,33(10):1093-1100

The influence of scaling court-size and net height on children’s tennis performance was examined. Sixteen boys (9.7 ± 0.5 years) had to perform a 30-min match in four different conditions, where court-size and/or net height were scaled by using a scaling ratio based on the differences in temporal demands between the children and the adult game. These 30-min matches were analysed using Tennis Analyst (FairPlay Ltd., Jindalee, QLD, Australia) software to determine typical tennis match performance characteristics. Children hit more winners, more forced errors, played more volleys, struck more shots from a comfortable height and played in a more forward court position when the net was scaled. Scaling both the court and net lead to a faster children’s game, more closely approximating what is typical of the adult game. The differences between the typical tennis performance variables recorded suggested that scaling the net led to a more aggressive way of playing. Further, children enjoyed playing on the standard court–scaled net condition more than standard adult conditions. It is suggested that optimising the scaling of net height may be as critical as other task constraints, such as racquet length or court-size, as it leads to a more engaging learning environment for experienced children.  相似文献   

Visual illusions and the control of ball placement in goal-directed hitting     

Caljouw SR  Van der Kamp J  Savelsbergh GJ 《Research quarterly for exercise and sport》2010,81(4):410-415

When hitting kicking, or throwing balls at targets, online control in the target area is impossible. We assumed this lack of late corrections in the target area would induce an effect of a single-winged Müller-Lyer illusion on ball placement. After extensive practice in hitting balls to different landing locations, participants (N = 9) had to hit a ball to a distant target specified by the vertex of a single-winged Müller-Lyer configuration. Impact velocity was not significantly "tricked" by the pictorial illusion, suggesting that, even when late corrections in the target area are absent, some motor behaviors are not susceptible to the influence of the visual environment surrounding the target.  相似文献

Value-Laden Science: Jan Burgers and Scientific Politics in the Netherlands     

Geert J. Somsen 《Minerva》2008,46(2):231-245

The political engagement of scientists is not necessarily left-wing, and even when it is, it can take widely varying forms. This is illustrated by the specific character of Dutch scientific activism in the 1930s and 40s, which took shape in a society where ‘pillarized’ social divisions were more important than horizontal class structure. This paper examines how, within this context, the Delft physicist Jan Burgers developed a version of scientific politics, built on a philosophy of value-laden science.

A History of Universalism: Conceptions of the Internationality of Science from the Enlightenment to the Cold War     

Geert J. Somsen 《Minerva》2008,46(3):361-379

That science is fundamentally universal has been proclaimed innumerable times. But the precise geographical meaning of this universality has changed historically. This article examines conceptions of scientific internationalism from the Enlightenment to the Cold War, and their varying relations to cosmopolitanism, nationalism, socialism, and ‘the West’. These views are confronted with recent tendencies to cast science as a uniquely European product.

Creating Appropriate Training Environments to Improve Technical,Decision-Making,and Physical Skills in Field Hockey     

Ewout A. Timmerman  Geert J. P. Savelsbergh  Damian Farrow 《Research quarterly for exercise and sport》2019,90(2):180-189

Purpose: The purpose of this study was to determine the influence of eight different small-sided games (SSG) on physical, technical, and decision-making demands of training environments in U14 field hockey. Methods: A total of 13 participants played eight different training games consisting of two 7.5-minute halves, where number of players (three per side or six per side) and/or field characteristics (normal game, cage hockey game, possession game, and two-goals game) was manipulated. Match performance was determined by using notational analysis, and physical demands were determined by using GPS analyses. Results: Findings revealed that lowering the number of players increased the number of technical actions performed per player and the physical demands of the SSG. Findings of the field characteristics manipulation revealed that the possession game forced players to control the ball more as a team, which resulted in more passes (+4.82 passes) and fewer dribbles (?1.48 dribbles) and tackles (?0.69 tackles) compared to the normal game. The two-goals game led to players scoring more goals (+0.61 goals) compared to the normal game, while the cage hockey game increased passing (+1.46 passes) and physical demands (+7.32 meters per minute) compared to the normal game. Conclusion: It can be concluded from these findings that coaches and trainers are able to promote a change in playing behavior, and in turn the development of skills, by manipulating specific constraints of the training environment.  相似文献   

Gender-inclusive game-based learning in secondary education     

Wilfried Admiraal  Jantina Huizenga  Irma Heemskerk  Els Kuiper  Monique Volman  Geert ten Dam 《International Journal of Inclusive Education》2013,17(11):1208-1218

Boys show a stronger preference for digital entertainment games than girls. For this reason, it may be that game-based learning is more acceptable to boys than to girls. Yet game-based learning might improve the performance of both boys and girls, depending upon the instructional design. In a quasi-experimental study with a secret-trail game, effects were examined on students' subject-matter knowledge. Analysis of covariance revealed that both boys and girls of the game intervention group showed a higher test performance, compared to students of the control group. However, different game activities mediated this effect of the secret-trail game on performance: girls seemed to profit more from searching the Internet to complete assignments and boys from competing with others. The performance of both boys and girls was negatively influenced by technical problems. The results are discussed within the framework of gender-inclusive game design.  相似文献   

Supports for children with disabilities in regular education classrooms: an account of different perspectives in Flanders     

Kathleen Mortier  Geert Van Hove  Elisabeth De Schauwer 《International Journal of Inclusive Education》2013,17(6):543-561

This paper presents the experiences and interpretations of children, parents, teachers and support persons concerning the implementation of supports in regular school environments in Flanders, Belgium. The data were gathered through observations, interviews and focus group meetings. Those multiple perspectives provide insights into the complexity of implementing supports in a regular education context. The conclusions offer some possibilities for debate and alternative ways of thinking about supports that facilitate inclusive school communities by tapping into resources such as the children, the environment, creativity and courage to leave the beaten path.  相似文献   

Leaving College: A Gender Comparison in Male and Female-Dominated Programs     

Sabine Severiens  Geert ten Dam 《Research in higher education》2012,53(4):453-470

Women, on average, outnumber men and are more successful in higher education. A literature overview showed that these differences may be explained by gender differences in learner characteristics, by external factors and by institutional factors. This study aims to explain gender differences in higher education in more detail by focusing on one of the recent research findings in this area: the role of the numerical representation of men and women in course programs. What are gender differences in study success in male and female-dominated course programs, and what are gender differences in reasons for leaving these programs? The research questions were answered by analyzing Dutch census data and conducting a survey on students that have left college. Results showed that gender differences in retention scores and reasons for leaving were indeed related to the numerical representation of women and men in course programs. Leaving female-dominated programs seemed to be a different matter from leaving male-dominated programs.  相似文献
