Inquiry-based learning: A socially just approach to higher education

Higher education’s potential to transform social and economic status and improve society, underlies increasing demands to improve access. But simply increasing access is not sufficient—it is important to ask whether our prevailing pedagogical approaches facilitate an effective and socially just higher education system. In other words, are traditional pedagogical approaches used in universities today truly accessible to the broader student population entering university? The current paper argues that the majority of pedagogies remain rooted in traditional approaches that favor those who benefit from continuous education from primary through to tertiary education. Such approaches rely heavily on incremental credentialism and are neither truly accessible nor socially just. Most introductory courses in universities require prior knowledge and “expect” students to be enculturated into a particular type of learning: as such, students with different levels of preparation, who come from different backgrounds, may be excluded from full participation. In addition, the rising costs of tuition fees and textbooks, and access to technology create inequities that reinforce socially-based discrimination higher education. The paper reports on the impact of implementing a specifically designed course, using closed-loop, reiterative problem-based learning, to create learning paradigms that focus on a more socially just approach for students entering university: these courses do not demand specific prior knowledge, foster difficult ways of thinking, and focus on developing research skills through access to library resources. Finally, the paper reports on students’ expectations about higher education and underscores the importance of re-thinking at least the first-year experience for students.     

A generational comparison of problem gambling and gambling attitudes among older adult gambling venue patrons

Gambling is a popular leisure activity for older adults (55+), and existing research suggests that overall older adults are less prone to problem gambling compared to younger cohorts. People born after World War II are now beginning to reach retirement age. The purpose of this article was to explore age-related cohort differences between people born from 1943 to 1960 compared to those born from 1925 to 1942 in their attitudes and behaviours related to gambling. This study employs a large sample (2103) of older adults collected at gambling locations across Southern Ontario, Canada in 2013. Comparisons were made using Pearson’s chi-squared tests for categorical variables and independent samples t-tests for continuous variables with logarithmic transformations for highly-skewed variables. Those of the 1943 to 1960 cohort showed significantly higher problem gambling scores and per visit spending, but lower numbers of visits per year. There was no discernible pattern between cohorts in terms of attitudes toward gambling. Assumptions of lower risk of problem gambling among older adults will have to be re-evaluated as the post-war generation becomes an ever greater proportion of older adults.     

《英属印度与西藏》摘译(四)

本文通过大量英文原始档案,叙述英国在两次鸦片战争得胜后,依从本土和在印商人同中国的西藏地方通商的要求,由英印选定锡金作为进入西藏的唯一途径,但派代表到边上联络或递信,都未成功。英印在锡金境内修路、廓尔喀上层趋向亲英,都激起藏民对英人的忌恨,拒绝英人入藏。英驻华公使向总理衙门屡次交涉西藏开放问题,不得结果。文中表露出这时期内英国仍然重视清朝在西藏拥有的主权地位。     

Internalized homophobia and depression in lesbian women: The protective role of pride

This study sought to examine the association between internalized homophobia and depressive symptoms in lesbian women, and establish whether such a relationship was mediated by collective self-esteem, self-esteem, and self-disclosure. Participants were 225 self-identified lesbian women in the community. Structural equation modeling was used to demonstrate that an underlying construct, labeled pride, reflected participants’ levels of self-esteem, collective self-esteem, and self-disclosure. Internalized homophobia was moderately and negatively predictive of pride, and pride was strongly and negatively predictive of depression. Results highlight the potentially protective role of pride in the prevention of depression among lesbian women.     

Cortisol Rise Following Awakening Among Problem Gamblers: Dissociation from Comorbid Symptoms of Depression and Impulsivity

Gambling pathology has been associated with elevated levels of distress, depression and impulsivity. The present investigation assessed whether these behavioral features would be evident among problem gamblers as they are among pathological gamblers. As well, given that gambling has been associated with increased life stress, as an objective index of ongoing distress, elevations of morning cortisol levels were assessed in problem and pathological gamblers relative to recreational gamblers, and their relations to depressive symptoms and impulsivity were assessed. Recreational, problem, and pathological gamblers (N = 140) completed the Beck Depression Inventory and the Barratt Impulsiveness Scale-11, and provided saliva samples at awakening, 30 min, 3.5 h, and 5.5 h afterward. Consistent with the view that problem and pathological gambling are associated with elevated life stressors, the rise of morning cortisol from awakening to 30 min following awakening was greater than in recreational gamblers. Heightened impulsivity was evident among both problem and pathological gamblers, whereas depressive symptoms were only evident among pathological gamblers. In neither instance were these psychological indices related to the morning cortisol rise. Indeed, increased depressive symptoms were not evident among problem gamblers, despite the fact that elevated morning cortisol levels were evident. The elevated morning cortisol rise may be secondary to gambling problems or distress related to gambling problems. Furthermore, the sustained morning cortisol elevations may be indicative of allostatic overload, and could potentially be a harbinger for potential health risks among problematic gamblers.     

Entropy-Based Moment Selection in the Presence of Weak Identification

Hall et al. (2007 Hall , A. R. , Inoue , A. , Jana , K. , Shin , C. (2007). Information in generalized method of moments estimation and entropy based moment selection. Journal of Econometrics 138:488–512.[Crossref] , [Google Scholar]) propose a method for moment selection based on an information criterion that is a function of the entropy of the limiting distribution of the Generalized Method of Moments (GMM) estimator. They establish the consistency of the method subject to certain conditions that include the identification of the parameter vector by at least one of the moment conditions being considered. In this article, we examine the limiting behavior of this moment selection method when the parameter vector is weakly identified by all the moment conditions being considered. It is shown that the selected moment condition is random and hence not consistent in any meaningful sense. As a result, we propose a two-step procedure for moment selection in which identification is first tested using a statistic proposed by Stock and Yogo (2003 Stock , J. H. , Yogo , M. ( 2003 ). Testing for weak instruments in linear IV regression . Discussion paper, Kennedy School of Government, Harvard University, Cambridge, MA . [Google Scholar]) and then only if this statistic indicates identification does the researcher proceed to the second step in which the aforementioned information criterion is used to select moments. The properties of this two-step procedure are contrasted with those of strategies based on either using all available moments or using the information criterion without the identification pre-test. The performances of these strategies are compared via an evaluation of the finite sample behavior of various methods for inference about the parameter vector. The inference methods considered are based on the Wald statistic, Anderson and Rubin's (1949 Anderson , T. W. , Rubin , H. ( 1949 ). Estimation of the parameters of a single equation in a complete system of stochastic equations .
