Abstract The purpose of this study was to determine the optimum release conditions for the free throw in men's basketball. The study used hundreds of thousands of three-dimensional simulations of basketball trajectories. Five release variables were studied: release height, release speed, launch angle, side angle, and back spin. The free throw shooter was assumed to shoot at 70% and to release the ball 2.134 m (7 ft) above the ground. We found that the shooter should place up to 3 Hz of back spin on the ball, should aim the ball towards the back of the ring, and should launch the ball at 52° to the horizontal. We also found that it is desirable to release the ball as high above the ground as possible, as long as this does not adversely affect the player's launch consistency. 相似文献

The number of contact hours, one of the important institutional context factors, was examined and compared between Dutch and
Vietnamese higher education at institute and student levels in Psychology and Business and/or Economics specializations. The
quantity of contact hours per credit point given by institutions was investigated in a number of Dutch and Vietnamese universities.
Additionally, 104 students in Groningen, the Netherlands, and 140 students in Hanoi and Ho Chi Minh City, Vietnam, participated
in the survey with a self-reported and self-assessed questionnaire on their study time allocation. Beside contact hours, other
learning process related factors such as study activities, motivation, quality of instruction, and generic skills were examined
to provide a better insight into these two systems. Results showed that Vietnamese students had significantly higher number
of contact hours than Dutch students while their generic skills, motivation and time spent on independent study were a lot
lower. 相似文献

Given the growing importance of online social media platforms (OSM) in brand management, the authors attempt to extend the relationship between e-brand equity and repurchase intention with two mediator variables, namely visual appeal and e-preference in which willingness to pay a price premium (WPPP) serves as a moderator. Drawing on the perspective of digitalized engagement (PDE), the authors confirm the mediating effects on the e-brand equity-repurchase intention link while evidencing both positive and negative effects of WPPP on the linkage of e-brand equity and mediators. Contributions to theory, practice, and future studies are also provided. 相似文献

This article examines the impact of subtractive schooling, including language use in education, on the identity of a group of ethnic minority students in Central Highlands of Vietnam. Drawing on semistructured interview data, a deeper look is taken into the ways in which these students identify themselves with their languages, cultures, and social relations. Findings reveal that the subtractive power of the school language and the institutional milieu profoundly influenced their identity construction by creating the conditions for (a) the devaluation of their language and cultural identity as a consequence of the invasion of their sociocultural territory by the dominant language and culture and (b) the segregation and disunity that affected their identity construction through social relations. Although subtractive schooling apparently facilitated students’ integration into the mainstream, its invisible power forced them not only to integrate but also to bear the full burden of constructing new identities to adjust to the school environment and the mainstream society. 相似文献

Neo-liberal educational policies that are being implemented globally work to foster competition among schools and teachers, as well as among children. In this situation, teachers must often come to accept the dominant representations of curricular policy developed by higher authorities. In this study, a case study design is used to describe how one school in Vietnam shifted away from this state of ‘colonisation’ by reforming the school under the framework of lesson study for learning community (LSLC). This paper subsequently argues that there is a need for school-level policies that democratise school culture and practices, resisting the negative impacts of colonising policies. 相似文献

Child care quality plays a crucial role in children's social and cognitive development. While child care quality is a critical issue for all children, it matters more for low-income children. Policy makers have increased the emphasis on allowing parents, not government, to make decisions about the type of care they want for their children. Yet most research on child care quality has focused on how child care professionals, not parents define high quality care. This study investigates how low-income families evaluate child care quality by examining the child care preferences of a sample of low-income African American parents. We employ the factorial survey method, a method used in sociological research to assess people's perceptions and rankings of individual attributes associated with complex multidimensional phenomena. The factorial survey method permits a simultaneous assessment of how respondents evaluate and make tradeoffs among multiple child care characteristics. We assess the impact of child care characteristics on respondents’ perceptions of child care desirability, fair market value, and willingness to pay. Findings indicate that parents’ definition of quality focused squarely on the care giving environment, specifically the qualifications, experience, training and behavior associated with the child care provider. The type of care facility—family, center, relative or neighbor care was largely irrelevant to this sample of parents. Parents believed that the characteristics they defined as desirable child care situations were worth more, and parents were willing to pay more for these characteristics. These parents also defined quality in terms of race and class, and they wanted racial and economic diversity. This research suggests parents may choose lower quality care, not because they do not know what quality is or because they define quality care differently, but because such care may be neither available nor affordable in their communities. 相似文献

The commercialisation of education and the massive recruitment of international students across different vocational education and training (VET) systems including the US, UK, Canada and Australia have led to significant changes in the VET teaching and learning landscape. This situation compels the VET sector to design and develop new professional development programs to support the immediate and changing needs of teachers working with the diverse international student cohort. However, to date, teacher professional development in response to the growing population of international students has not been an explicit focus of empirical study and theoretical conceptualisation in VET research. This study responds to this paucity. It draws on a broader three-year research project funded by the Australian Research Council (2014–2017) that involves fieldwork, participation in and observation of staff professional development activities and interviews with 102 VET staff in Australia. It uses positioning theory as a conceptual framework to examine how VET teachers position themselves and their professional development needs in response to international students. The results call for a critical need to re-examine the focus of the current professional development programs offered for VET teachers. The current context requires teacher professional development in international VET to focus on developing teachers’ capabilities to re-examine their pedagogical beliefs and practices and to understand international students’ various needs and cultural backgrounds. The study also stresses the importance of ongoing professional learning to equip teachers with the skills and knowledge to appropriate their pedagogical practices in response to the critical need to prepare all students for the intercultural labour market and to use students’ diversity as a resource for teaching and learning. 相似文献

Providing research consultations is an essential job responsibility for all academic librarians. One software option that can help to facilitate the process of scheduling research consultations is Springshare’s Appointments Scheduler (SAS), a feature within their LibCal software product. SAS has a number of features that make it easy for patrons and librarians to create, manage, and optimize the appointment. This article describes the SAS product and provides tips and recommendations that will help librarians to leverage all of its features. 相似文献
