Critical Conversations on Social Justice in Undergraduate Mathematics

Abstract

This article explores how critical conversations engage undergraduate mathematics faculty in a community of practice that enhances their knowledge about teaching and learning mathematics for social justice. More broadly, critical conversations are defined as a cooperative learning strategy that can be used to identify, explore, and respond to various interests and issues situated across differing values and beliefs. We present a case study of a critical conversation that took place at a 2016 Mathematics for Social Justice workshop organized by a group of junior faculty. Participant reflections situate perspectives that can help novice and experienced instructors design conversations about teaching mathematics for social justice. Specifically, individual and group reflections highlight the importance of: (i) framing and reflecting on the conversation; (ii) exploring implications and content connections; and (iii) identifying barriers. Implications for faculty members and mathematics departments are provided.     

Multitasking,but for what benefit? The dilemma facing Nigerian university students regarding part-time working

Students working part-time while studying for a full-time university degree are commonplace in many Western countries. This paper, however, examines the historically uncommon part-time working activities and career aspirations among Nigerian university students. In particular, how working is perceived to contribute to developing employability skills, and whether it is influenced by their self-efficacy. Survey data from 324 questionnaires were collected from a federal university, although the data analysis used a mixed method. The findings indicate that despite low levels of part-time working generally among students, older, more experienced, higher level and female students place a premium on the skills that part-time work can develop. Moreover, self-efficacy and being female is a significant predictor in understanding part-time work and career aspirations. This study offers originality by focusing on students’ part-time work, the value working provides and its link with career aspirations, within a relatively unexplored context of Nigeria.     

Cow's milk as a post-exercise recovery drink: implications for performance and health

Abstract

Post-exercise recovery is a multi-facetted process that will vary depending on the nature of the exercise, the time between exercise sessions and the goals of the exerciser. From a nutritional perspective, the main considerations are: (1) optimisation of muscle protein turnover; (2) glycogen resynthesis; (3) rehydration; (4) management of muscle soreness; (5) appropriate management of energy balance. Milk is approximately isotonic (osmolality of 280–290?mosmol/kg), and the mixture of high quality protein, carbohydrate, water and micronutrients (particularly sodium) make it uniquely suitable as a post-exercise recovery drink in many exercise scenarios. Research has shown that ingestion of milk post-exercise has the potential to beneficially impact both acute recovery and chronic training adaptation. Milk augments post-exercise muscle protein synthesis and rehydration, can contribute to post-exercise glycogen resynthesis, and attenuates post-exercise muscle soreness/function losses. For these aspects of recovery, milk is at least comparable and often out performs most commercially available recovery drinks, but is available at a fraction of the cost, making it a cheap and easy option to facilitate post-exercise recovery. Milk ingestion post-exercise has also been shown to attenuate subsequent energy intake and may lead to more favourable body composition changes with exercise training. This means that those exercising for weight management purposes might be able to beneficially influence post-exercise recovery, whilst maintaining the energy deficit created by exercise.

MUTUAL PERSPECTIVE‐TAKING: A PRESUPPOSITION OF ENLIGHTENED TOLERANCE

The starting point for this article is the thesis that enlightened tolerance presupposes the ability of perspective‐taking and the willingness to act accordingly. In order to develop this thesis, the first step is a consideration of certain major conceptions of tolerance as they have been developed in philosophy and the theory of science. The second step is a presentation of the concept of perspectivity and the argument that it is only by means of the reciprocity of perspective‐taking that enlightened tolerance can be achieved and maintained.     

Why So Many Repositories? Examining the Limitations and Possibilities of the Institutional Repositories Landscape

Academic libraries fail to take advantage of the network effect because they manage too many digital repositories locally. While this argument applies to all manner of digital repositories, this article examines the fragmented environment of institutional repositories (IR), in which effort and costs are duplicated, numerous software platforms and versions are managed simultaneously, metadata are applied inconsistently, users are served poorly, and libraries are unable to take advantage of collective data about content and users. In the meantime, commercial IR vendors and academic social networks have shown much greater success with cloud-based models. Collectively, the library profession has enough funding to create a national-level IR, but it lacks the willingness to abandon local control.     

明代《说文》学述略

《说文解字》是我国最重要的文字学著作之一，以至形成文字学史上专门的“说文学”。“说文学”以清代为最盛，同清代相比，明代对《说文》的研究则显得异常萧务，故这段时期的说文学往往被学界所忽视。本文从时代学风、版刻情况、研究情况、传承发展几个方面时明代说文学大体状况作了简要梳理。
