Movement patterns and physical strain during a novel, simulated cricket batting innings (BATEX) 总被引:1,自引:1,他引:0
A simulated cricket batting innings was developed to replicate the physical demands of scoring a century during One-Day International cricket. The simulated innings requires running-between-the-wickets across six 5-over stages, each of 21 min duration. To validate whether the simulated batting innings is reflective of One-Day International batting, movement patterns were collected using a global positioning system (GPS) and compared with previous research. In addition, indicators of physical strain were recorded (heart rate, jump heights, sweat loss, tympanic temperature). Nine club cricketers (mean ± s: age 20 ± 3 years; body mass 79.5 ± 7.9 kg) performed the simulated innings outdoors. There was a moderate trend for distance covered in the simulated innings to be less than that during One-Day batting (2171 ± 157 vs. 2476 ± 631 m · h?1; effect size = 0.78). This difference was largely explained by a strong trend for less distance covered walking in the simulated innings than in One-Day batting (1359 ± 157 vs. 1604 ± 438 m · h?1; effect size = 1.61). However, there was a marked trend for distance covered both striding and sprinting to be greater in the simulated innings than in One-Day batting (effect size > 1.2). Practically, the simulated batting innings may be used for match-realistic physical training and as a research protocol to assess the demands of prolonged, high-intensity cricket batting. 相似文献

How well do governments comply with their own transparency statutes? Alarmingly, answers to this question are in short supply because of patchy comparative data. This study begins to address this gap by analyzing an exhaustive compilation of 265 transparency compliance evaluations (i.e. audits) authored by NGOs, academics, and government oversight authorities across Latin America between 2003 and 2018. Aggregating data on patterns of evaluation and public sector compliance with transparency statutes, we find modest increases in compliance over time, strikingly low compliance with passive transparency compliance (i.e. governmental responses to citizen requests) at the local versus national levels of government, and significantly higher compliance scores when government oversight agencies act as evaluators. Our data also reveal worrying gaps in evaluation efforts. Evaluators tend to focus far more on active transparency (i.e. website-based disclosure) than passive transparency, more on national level governments than subnational governments, and preponderantly on the executive as opposed to legislative or judicial branches of government. Textual analyses show that education is the most evaluated policy theme, with financial policies and social services close behind. In presenting the first large-scale cross-national assessment of transparency compliance, the current study brings to light trends in the effectiveness of transparency regimes and patterns of transparency evaluation across Latin America. 相似文献

The aim of this article is to make a close case study of one teacher’s teaching in relation to established traditions within
science education in Sweden. The teacher’s manner of teaching is analysed with the help of an epistemological move analysis.
The moves made by the teacher are then compared in a context of educational philosophy and selective tradition. In the analyses
the focus is to study the process of teaching and learning in action in institutionalised and socially shared practices. The
empirical material consists of video recordings of four lessons with the same group of students and the same teacher. The
students are all in Year 7 in a Swedish 9-year compulsory school. During these lessons the students work with a subject area
called “Properties of materials”. The results show that the teacher makes a number of different moves with regard to how to
proceed and come to a conclusion about what the substances are. Many of these moves are special in that they indicate that
the students need to be able to handle the procedural level of school science. These moves do not deal directly with the knowledge
production process, but with methodological aspects. The function of the moves turns the students’ attention from one source
of knowledge to another. The moves are aimed at helping the students to help themselves, since it is through their own activity
and their own thinking that learning takes place. This is characteristic in the teacher’s manner of teaching. When compared
in a context of educational philosophy, this manner of teaching has similarities with progressentialism; a mixture of essentialism
and progressivism. This educational philosophy is a central aspect of what is called the academic tradition—a selective tradition
common in science education in Sweden between 1960 and 1990. 相似文献

Neoliberalism has become a highly dominating and taken-for-granted way of organising the university sector around the world. In the critical educational literature, this market-based rationality has been scrutinised in detail over the past decades. However, rather scant attention has been directed to how university managers and administrators, apart from setting up quasi-markets, may intervene more directly to give the invisible hand of the market a helping hand. Aiming to address this lacuna, the purpose of the current article is to develop an empirically grounded taxonomy of different types of such interventions, and to theorise them in terms of the different facets of the neoliberal milieu that they reproduce and the various forms of subjectivising work among academics that they seek to engender. We do so by means of a qualitative study of so-called ‘Grants Offices’ at three Swedish universities. The findings arguably add to and problematise our understanding of how neoliberal markets work in academia in three different ways. First, while extant research has noted that university managers and administrators may intervene beyond the setting up of neoliberal markets per se, our study is to our knowledge the first one that identifies and systematises a broad array of such interventions. Second, it problematises the view of neoliberal markets as a form of monolithic entity that produces a uniform competitive pressure on academics. Third, and related, it furthers our understanding of the type of subjectivity that competitive milieus are assumed to bring about. 相似文献

Previous research on how students’ acceptance of emotionally charged theories relates to their understanding is based on the measurement of acceptance and understanding as two separate variables. As an alternative, the present study takes a qualitative approach with the aim of exploring what 24 upper-secondary school students accept when they come to understand the concept of gender and how to justify gender-related statements. The results show how the students accept ideas about social structures, power, and emancipation, as well as ideas about essences, individual independence, and a natural order. As for their justifications, they accept ideals of equality and objectivity. By assuming that the ideas have positive connotations for the students, it becomes possible to understand them as engaged in negotiating norms that are brought to the fore in the interviews. 相似文献

A supportive relationship between teachers and students has been shown to have positive effects on students’ performance and social development. Preservice teachers’ relational competence is, however, an unexplored area. The purpose of this study is to contribute to educational research about relational competence in teacher education by introducing a Swedish project which focuses on interpersonal aspects. The study has three parts. In the theoretical part, a conceptualization of teachers’ relational competence using Thomas Scheff’s theory of interpersonal relationships is outlined. In the empirical (pilot) part, a methodology for prompting preservice teachers’ analyses of teacher–student relationships is described, as well as a thematic analysis of their responses. The theoretical conceptualization is then used together with the empirical data in the third part, in order to identify development needs of preservice teachers in terms of relational competence. According to the conceptualization, relational competence includes three sub-concepts: communicative, differentiation, and socio-emotional competence. From the analysis of preservice students’ texts, the article identifies development needs in relation to the three sub-concepts. The concluding discussion focuses on lessons learned from the study regarding how to promote teacher students’ relational competence. 相似文献

We provide a new statistical model developed from the alumni database at North-western University for identifying potential
major gift donors. Our logit model with interactions predicts which individuals will give $10,000 or more over three years
using CHAID (Chi-square Automatic Interaction Detection) combined with logit analysis. Our work goes beyond our earlier research
(Lindahl and Winship, 1992) by providing a more effective means of selecting fund-raising prospects. The critical new component
in our model is the inclusion of interactions between past giving and other variables. Specifically, we find that for individuals
with different past giving records different variables are important. Our results show that prospects with a low past giving
level will rarely give gifts over $10,000. 相似文献

Two important roles of education are to provide students with knowledge for their democratic participation in society and
to provide knowledge for a future profession. In science education, students encounter values that may be in conflict with
their worldview. Such conflicts may, for example, lead to constructive reflections as well as rejection of scientific knowledge
and technology. Students’ ways of reasoning are important starting points for discussing problematic issues and may be crucial
for constructive dialogues in the classroom. This study investigates students’ reasoning about conflicting values concerning
the human-animal relationship exemplified by the use of genetically modified pigs as organ donors for xenotransplantation.
Students’ reasoning is analyzed using Giddens’ concepts of disembedded and embedded practices in parallel with moral philosophical
theories in a framework based on human-animal relationships. Thirteen students were interviewed and their stances categorized.
Kantian deontological and classical utilitarian ethics were found within the patronage and the partnership models. These students
appreciated expert knowledge but those using the partnership model could not accept xenotransplantation if pigs were to be
killed. Students using care ethics did not appreciate expert knowledge since it threatened naturalness. The results suggest
that stances against the use of scientific knowledge are more problematic than knowledge per se, and that conflicting stances
have similarities that present opportunities for understanding and development of students’ argumentation skills for future
participation in societal discourse on utilizing expert knowledge. Furthermore it is argued that science education could benefit
from a higher awareness of the presence of different morals. 相似文献

In German sports science, the national elite sport promotion system is a steady topic of discussions. The federal government and the German Olympic Sports Confederation (DOSB) expect new impetus of the reformed elite sport system in the areas of, inter alia, young athlete promotion, scientific support, and the coaches’ situation in German elite sport. The present article is a discipline-specific approach to these three issues for men’s artistic gymnastics. The first author served in various functions in German gymnastics (former squad athlete, young athletes‘ coach, academic teaching) for several years and is familiar with essential problems due to close communication with gymnasts, coaches, scientists, and officials. The purpose of this article is to point out specific challenges in men’s artistic gymnastics in view of the present debate on the German elite sport promotion system. This is intended to stimulate further discussions on solution approaches concerning the common exploitation of potentials. 相似文献
