The notion that the stories of our lives shape dispositions towards imagined futures is another lens through which university underrepresentation should be viewed. A storied lens attends to how futures, like university attendance, are storied during childhood to the extent that some youth imagine, and therefore plan, these futures as natural progression. Such was the case for study participants, indicating that childhood stories contain answers for mitigating social reproduction connected to parental education and cultural forces within the home. Examining social mobility through the underexplored storied-futures grand narrative presents unique solutions that lay hidden within the dominant meritocratic grand narrative.  相似文献

Sprint and distance running have experienced remarkable performance improvements over the past century. Attempts to forecast running performances share an almost similarly long history but have relied so far on relatively short data series. Here, we compile a comprehensive set of season-best performances for eight Olympically contested running events. With this data set, we conduct (1) an exponential time series analysis and (2) a power-law experience curve analysis to quantify the rate of past performance improvements and to forecast future performances until the year 2100. We find that the sprint and distance running performances of women and men improve exponentially with time and converge at yearly rates of 4% ± 3% and 2% ± 2%, respectively, towards their asymptotic limits. Running performances can also be modelled with the experience curve approach, yielding learning rates of 3% ± 1% and 6% ± 2% for the women's and men's events, respectively. Long-term trends suggest that: (1) women will continue to run 10–20% slower than men, (2) 9.50 s over 100 m dash may only be broken at the end of this century and (3) several middle- and long-distance records may be broken within the next two to three decades. The prospects of witnessing a sub-2 hour marathon before 2100 remain inconclusive. Our results should be interpreted cautiously as forecasting human behaviour is intrinsically uncertain. The future season-best sprint and distance running performances will continue to scatter around the trends identified here and may yield unexpected improvements of standing world records.  相似文献

Barack Obama's My Brother's Keeper is designed to narrow persistent gaps that boys and young men of color confront often and to help all young people achieve their potential in college and career. An important part of this initiative is comprehensive mentoring that supports students in schools and in communities. Because ethnic-minority students have extremely low graduation rates in high school and college, an essential question is addressed: Can My Brother's Keeper and similar initiatives with a mentoring component be effective in helping minority students to achieve success in elementary and secondary schools and in college?  相似文献

Quality models for online and blended learning (OBL) have mainly been developed in higher education. The literature indicates that these models are often conceptualised from the providers’ perspective. What is important for the quality of OBL from the students’ perspective has recently received increased attention in the literature. Consensus among stakeholders about students’ quality needs is useful to support dialogue between professionals to strategically adopt OBL and to ensure that the needs of students are met. This study aims to validate a quality instrument for OBL, taking a set of 74 quality indicators and analysing them in terms of seven success factors (credibility, accessibility, transparency, flexibility, interactivity, personalisation, productivity). The Delphi method was selected as most suited. Participants from adult education were asked to indicate on a 7-point Likert scale to what extent the indicators add to OBL quality to meet students’ needs. After four Delphi rounds, the participants agreed on definitions of success factors and 30 indicators. The results are useful for institutions, ministries of education and external quality assessment agencies to assess the quality of OBL and can support institutions to implement improvement actions to ensure that the needs of students are met.  相似文献
