This essay examines the educational opportunities of people in poverty who receive social welfare assistance. The dominant political theory underlying social policy (including education policy) in the United States has evolved from 1960s and 1970s welfare liberalism into 1980s and 1990s style neo‐conservatism—a theory that embraces principles of the market and individual liberty as paramount social values. Against this backdrop, I review two recent books that provide compelling evidence for this turn and I call for increased understanding of the relationship between social welfare policies and higher education opportunities for those in poverty. 相似文献

In team sports, tactical periodisation refers to the planned manipulation of training loads with the aim of prioritising athlete readiness for matches of greatest importance. Although monitoring of athletes’ physical condition is often used to inform this planning, the direct influence of external factors on match difficulty has not been well quantified. In this study, a ‘match difficulty index’ (MDI) for use in Super Rugby was developed, based on the influence imparted by five external factors on previous match outcomes. Specifically, information relating to match location, days break between matches, time-zone change and opposition ladder position (both current and previous year) were collected for matches played during the 2011–2013 Super Rugby seasons. Logistic regression analyses were used to assess the importance of each of these factors with respect to match outcome (win/loss), with opposition ladder position and match location (home, domestic away or international) exerting the greatest influence on match difficulty. Three separate cross-validated models were constructed, with match outcome classification performance reported as 66.2%, 65.5% and 63.7% respectively. The three MDI models emanating from this study can each be used to inform tactical periodisation program design both prior to and during the regular season. 相似文献
