Comparison of biomechanical characteristics between male and female elite fast bowlers

This study investigated ball release speed and performance kinematics between elite male and female cricket fast bowlers. Fifty-five kinematic parameters were collected for 20 male and 20 female elite fast bowlers. Group means were analysed statistically using an independent samples approach to identify differences. Significant differences were found between: ball release speed; run-up speed; the kinematics at back foot contact (BFC), front foot contact (FFC), and ball release (BR); and the timings between these key instants. These results indicate that the female bowlers generated less whole body linear momentum during the run-up than the males. The male bowlers also utilised a technique between BFC and FFC which more efficiently maintained linear momentum compared to the females. As a consequence of this difference in linear momentum at FFC, the females typically adopted a technique more akin to throwing where ball release speed was contributed to by both the whole body angular momentum and the large rotator muscles used to rotate the pelvis and torso segments about the longitudinal axis. This knowledge is likely to be useful in the coaching of female fast bowlers although future studies are required to understand the effects of anthropometric and strength constraints on fast bowling performance.     

Repeated reading to enhance fluency: Old approaches and new directions

As phoneme awareness deficits and resulting decoding weaknesses are increasingly addressed, there is heightened awareness of the role of fluency in reading. This paper reviews the history of fluency training, discusses the theoretical bases of such training, and summarizes the current knowledge about the efficacy of training procedures. We focus on Repeated Reading (RR), the most familiar and researched approach to fluency training. Outcome data on Repeated Reading, presented in the form of questions, is meant to answer practitioners’ questions about implementation and efficacy and to provide a starting point for researchers interested in the topic. Although some answers are straightforward, others indicate the subtleties involved in answering the broad question, “Does Repeated Reading work?” In addition to a list of practical suggestions based on Repeated Readings findings, three new approaches to fluency training are introduced.     

Leadership Stereotypes and Styles of Female Singaporean Principals

This paper investigates how a sample of female Singaporean secondary school principals perceived their leadership styles and compares their responses to a similar study carried out recently of female English head teachers. The education systems of England and Singapore are quite different. The English environment allows schools significant autonomy in personnel management and the majority of head teachers and senior managers are male. In contrast, the Singaporean educational environment is quite centralized, including the management of career paths, and the proportion of female senior managers is much higher. Interviews were conducted with 11 female Singaporean principals to identify their styles of management, leadership perspectives, and attitudes. The discussion first focuses on whether or not the styles of the principals in relation to ‘masculine’ or feminine’ stereotypes of leadership were similar to those of the English head teachers. Further comparison is made of the leadership attributes of the two sets of principals, including styles of management, decision‐making, working environment, need for vision, and values.     

Cultural aspects of nonverbal communication

A review of the literature on cultural aspects of nonverbal communication reveals the existence of both similarities and differences in the display of nonverbal behavior. It is argued that similarities are most manifest when analysis is at the level of the individual and the focus is on the objective, formal properties of the behavior; differences are more likely to become manifest when the analysis is at the level of the relationship between individuals and the focus is on the interpersonal import of the behavior. Material on gaze and eye contact, body motion and gesture, interpersonal distance and touch, facial expression, and paralanguage is surveyed and organized into three primary sections. The sections reflect the major functions nonverbal behavior is presumed to perform: (1) the sending of emotional states; (2) the conveying of interpersonal attitudes, particularly intimacy and status; and (3) the management of conversation. Implications are drawn concerning potential miscommunication in intercultural encounters.     

Physical activities and sedentary pursuits in African American and Caucasian girls

The purposes of this study were to describe and compare the specific physical activity choices and sedentary pursuits of African American and Caucasian American girls. Participants were 1,124 African American and 1,068 Caucasian American eighth-grade students from 31 middle schools. The 3-Day Physical Activity Recall (3DPAR) was used to measure participation in physical activities and sedentary pursuits. The most frequently reported physical activities were walking, basketball, jogging or running, bicycling, and social dancing. Differences between groups were found in 11 physical activities and 3 sedentary pursuits. Participation rates were higher in African American girls (p < or = .001) for social dancing, basketball, watching television, and church attendance but lower in calisthenics, ballet and other dance, jogging or running, rollerblading, soccer, softball or baseball, using an exercise machine, swimming, and homework. Cultural differences of groups should be considered when planning interventions to promote physical activity.     

The Case for Natural History

Fundamental knowledge of natural history is lacking in many western societies, as demonstrated by its absence in school science curricula. And yet, to meet local and global challenges such as environmental degradation, biodiversity loss and climate change, we need to better understand the living and non-living parts of the natural world. Many have argued passionately for an increased understanding of natural history; others have developed successful pedagogical programmes for applying knowledge of natural history in environmental initiatives. In joining wider calls, we choose here to focus on the educational value afforded by understanding the epistemological bases of natural history and its particular forms of reasoning. We also briefly discuss the ways in which an education in natural history provides the foundation for environmental and social justice efforts that directly affect the lives of young people and their communities. We end by highlighting the ease by which natural history may be incorporated in learning opportunities both in and outside of the classroom.     

Democracy,caring and competence: values perspectives in ECEC curricula in the Nordic countries

The aim of the study is to explore how Nordic Early Childhood Education and Care policies frame values education in preschools with a special focus on the values of democracy, caring and competence. The study is part of a larger Nordic project, Values education in Nordic preschools: Basis of education for tomorrow, the aim of which is to explore values education from various perspectives, policy levels, institutional levels and personal levels. The study applies Habermas’s theoretical ideas of communicative actions, lifeworld, and the system. Here the focus is on the system level, namely, values in national curriculum guidelines that serve as the basis of pedagogical practices in preschools in the Nordic countries. Thematic research analysis described by Braun and Clarke inspired the qualitative analysis of the documents. In addition, a quantitative language-based approach was applied to the study. Keywords related with democratic, caring and competence values were selected. The findings reveal different dimensions and meanings of the three value fields, such as democracy as being and/or becoming; care as fulfilment of basic needs and an ethical relationship; and competence values as learning for sociality and academic skills.     

Engagement of Academic Libraries and Information Science Schools in Creating Curriculum for Sustainability: An Exploratory Study

In 2010, the Association for the Advancement of Sustainability in Higher Education released, “Sustainability curriculum in higher education: A call to action,” encouraging infusion of sustainability topics into universities' teaching and research. Since then, academic programs and research related to social, economic, and environmental sustainability have enriched university curricula. An exploratory study was conducted to determine the position and engagements of academic libraries and information science schools in their contributions to scholarly sustainability activities and curricular initiatives. This article presents the results of the study which reveals a number of engagements by library professionals in the areas of sustainability, such as increasing open access to research, building sustainability-related collections and research guides, and incorporating sustainability content into information literacy. While academic libraries and information science schools are engaged in a broad spectrum of initiatives that support their institutions' sustainability research and curricular functions, this study indicates that such activities require a more targeted approach.
