The analysis and forecasting of male cycling time trial records established within England and Wales
The format of cycling time trials in England, Wales and Northern Ireland, involves riders competing individually over several fixed race distances of 10–100 miles in length and using time constrained formats of 12 and 24 h in duration. Drawing on data provided by the national governing body that covers the regions of England and Wales, an analysis of six male competition record progressions was undertaken to illustrate its progression. Future forecasts are then projected through use of the Singular Spectrum Analysis technique. This method has not been applied to sport-based time series data before. All six records have seen a progressive improvement and are non-linear in nature. Five records saw their highest level of record change during the 1950–1969 period. Whilst new record frequency generally has reduced since this period, the magnitude of performance improvement has generally increased. The Singular Spectrum Analysis technique successfully provided forecasted projections in the short to medium term with a high level of fit to the time series data. 相似文献

During late childhood and early adolescence, there is a dramatic increase in cognitive skills which influences how young people begin to think about their futures. The construct of possible selves has been used to help understanding of adolescents’ views of their future plans and goals by exploring their social perceptions to gain insight about how they think about the world and themselves. This study examined the role of perceived teacher support in adolescents’ development of possible selves. Results suggest that the four groups (White males, Latinos, White females and Latinas) in this study think in different ways about their future possible selves of graduating from a 4-year university. This study provides important theoretical as well as practical implications. 相似文献

This cross-sectional analysis examined the influence of school and household water, sanitation, and hygiene (WASH) conditions on recent primary school absence in light of other individual, household, and school characteristics in western Kenya. School latrine cleanliness was the only school WASH factor associated with reduced odds of absence. The marginal effect of household characteristics, such as distance to water source, child involvement in water collection, and presence of a latrine, differed by gender. Demographic features were more important predictors of absence, suggesting that interventions to improve attendance must consider existing differentials attributable to gender, socio-economic status, and other household characteristics. 相似文献

Since the establishment of the Islamic Republic, female higher education has been characterised by a paradoxical combination
of discrimination and exclusion, on the one hand, and increasing equality and empowerment, on the other. This study focuses
on the triangle of education, equality and empowerment, using Sara Longwe’s women’s empowerment framework to analyse the interplay
between the three. State policies to Islamise the universities during the 1980–1983 Cultural Revolution determined the “gender
appropriateness” of each specialisation and led to the exclusion of women from “masculine” fields of study during the early
years of the revolution. Despite such discriminatory measures, women today represent the majority of students in all fields,
except engineering. Women, however, remain underrepresented at graduate levels of education and as faculty members. An important
challenge is to understand why men are not entering different specialisations and whether there is a possibility of “re-doing
gender” – this time in addressing male inequality and disempowerment at undergraduate levels. 相似文献

New high-frequency, automated data collection and analysis algorithms could offer new insights into complex learning processes, especially for tasks in which students have opportunities to generate unique open-ended artifacts such as computer programs. These approaches should be particularly useful because the need for scalable project-based and student-centered learning is growing considerably. In this article, we present studies focused on how students learn computer programming, based on data drawn from 154,000 code snapshots of computer programs under development by approximately 370 students enrolled in an introductory undergraduate programming course. We use methods from machine learning to discover patterns in the data and try to predict final exam grades. We begin with a set of exploratory experiments that use fully automated techniques to investigate how much students change their programming behavior throughout all assignments in the course. The results show that students’ change in programming patterns is only weakly predictive of course performance. We subsequently hone in on 1 single assignment, trying to map students’ learning process and trajectories and automatically identify productive and unproductive (sink) states within these trajectories. Results show that our process-based metric has better predictive power for final exams than the midterm grades. We conclude with recommendations about the use of such methods for assessment, real-time feedback, and course improvement. 相似文献

In line with global trends, the rate of Iranian female students' enrolment in higher education has increased. However, some policy makers have been concerned about this and without considering the female voice, they have implemented strategies to balance the labour market, which has led to a decrease in female students in certain majors. The results of an empirical study showed that going to university is the primary route to empowerment for girls in Iran. The study into the meaning of empowerment adopted a qualitative approach using unstructured in‐depth interviews with 80 Iranian female university students from seven provinces of Iran. The narrative responses were analysed using content analysis and grounded theory. The results of this study led to develop a new theory called ‘Female Empowerment through Higher Education’, which has several key constituents of female empowerment including: social presence, the power to make decision, autonomy, education and building up a new value framework. 相似文献
