Longer-term effects of minimalist shoes on running performance,strength and bone density: A 20-week follow-up study*

This study investigated whether male runners improve running performance, running economy, ankle plantar flexor strength, and alter running biomechanics and lower limb bone mineral density when gradually transitioning to using minimalist shoes for 100% of weekly running. The study was a planned follow-up of runners (n?=?50) who transitioned to minimalist or conventional shoes for 35% of weekly structured training in a previous 6-week randomised controlled trial. In that trial, running performance and economy improved more with minimalist shoes than conventional shoes. Runners in each group were instructed to continue running in their allocated shoe during their own preferred training programme for a further 20 weeks while increasing allocated shoe use to 100% of weekly training. At the 20-week follow-up, minimalist shoes did not affect performance (effect size: 0.19; p?=?0.218), running economy (effect size: ≤?0.24; p?≥?0.388), stride rate or length (effect size: ≤?0.12; p?≥?0.550), foot strike (effect size: ≤?0.25; p?≥?0.366), or bone mineral density (effect size: ≤?0.40; p?≥?0.319). Minimalist shoes increased plantar flexor strength more than conventional shoes when runners trained with greater mean weekly training distances (shoe*distance interaction: p?=?0.036). After greater improvements with minimalist shoes during the initial six weeks of a structured training programme, increasing minimalist shoe use from 35% to 100% over 20 weeks, when runners use their own preferred training programme, did not further improve performance, running economy or alter running biomechanics and lower limb bone mineral density. Minimalist shoes improved plantar flexor strength more than conventional shoes in runners with greater weekly training distances.     

Tuition Discounting for Revenue Management

Over the past decade, institutionally-funded financial aid (or “tuition discounts”) have been the fastest-growing item within most public four-year college and university operating budgets. One explanation for this trend is due to the changing structure of public colleges’ revenue streams, as tuition and fees have replaced state appropriations as a viable and predictable source of funding. This analysis explores the extent to which expenditures on institutionally-funded financial aid generates additional revenue for public four-year colleges and universities. Using institutional data (n = 174) from 2002 to 2008, the analysis implements a generalized method of moments (GMM) technique and concludes that aid indeed can be leveraged for revenue generation. However, this relationship is only sustainable to a certain point. When unfunded tuition discount rates exceed approximately 13%, institutions may experience diminishing revenue returns to this financial aid investment.     

Career choice status among undergraduates and the influence of career management competencies and perceived employability

This study examines the influence of career management competencies and perceived employability on career choice status (CCS) among undergraduates. Making informed and appropriate career choices is positively linked with well-being, work performance and academic and career success. Early career decision-making is now critical if students wish to succeed in highly competitive graduate labour markets. This study gathered quantitative data from 370 Business undergraduates in an Australian and UK university. Findings suggest that students have largely made career decisions and are reasonably satisfied with their choices. CCS varied with age, stage of study, perceived employability and student capabilities in career self-management. Findings highlight the need for universities to not only equip students with the necessary skills to enter their chosen career but also – in collaboration with industry – develop strategies to engage students in the different aspects of career self-management earlier on in their studies.     

Critical Review of Mary Midgley's Intelligent Design Theory and Other Ideological Problems

Mary Midgley's pamphlet Intelligent Design Theory and Other Ideological Problems has been a widely read contribution to discussions of the place of creationism in schools. In this critique of her account, I outline Midgley's view of the relations between science and religion, her claims about what material can legitimately appear in science lessons, and her account of the nature of religion. I argue that she is mistaken in all three areas, and show that her most plausible reply to these criticisms also fails. Finally, I offer some thoughts on the proper relations between science and religion in the classroom.     

Critical Explorations of Human Rights: Recent and Selected Works

Abstract

The author provides an overview of recent critical works on human rights that constitute important contributions to the literature and ties together key threads from the discourse. Monographs, edited collections, and select articles on human rights are examined that draw primarily on critical legal theory and feminist approaches, among others, such as radical democracy and radical cause lawyering. Also explored are intersections between the critical human rights scholarship surveyed and recent works on ecological feminism and environmental human rights. The author argues that such collected works are invaluable contributions for those seeking transformative approaches to law and social change through the critical human rights lens.     

School experience influences on pre-service teachers' evolving beliefs about effective teaching

This study systematically tracked a group of 37 pre-service teachers' evolving beliefs about and perceptions of themselves and their experiences from the initial data collection prior to any experiential base in schools through the varied phases of their professional placements involving steadily increasing levels of professional responsibility. The results indicated that the pre-service teachers' beliefs about good teaching evolved from a belief in being in control through expertise to a belief in being in control through charisma and building relationship with their students. The first teaching practicum experience dramatically challenged the beliefs of these students where the beliefs indicated immediately after the experience to be more focussed on ‘self’ rather than students. Subsequent belief structures differed in character from both those after the first teaching experience and from those held prior to the first teaching responsibility. The study also reports on the pre-service students' self-efficacy beliefs in good teaching. Gender differences are also discussed.     

A theory of change for student-led academic integrity

Breaches in academic integrity are a pervasive and enduring international concern to the overall quality of higher education. Despite students being the group most affected by academic integrity policies, organisational culture is such that students tend to be passive recipients of change initiatives, rather than the drivers. To deliver a paradigm change, a theory of change framework was designed, implemented and applied to explore the viability of a student-led academic integrity society. To achieve this, a national research project involving three stages of data collection (surveys, interviews and focus groups) was conducted to obtain the perspectives of students and student representatives. The key outcome of the project has been the recent launch of an academic integrity student society, a novel initiative outside the United States of America. The theory of change framework presented here seeks to offer guidance to other institutions contemplating the viability of student-led change to academic integrity and the establishment of academic integrity student societies, in particular.     

The diminishing signaling value of patents between early rounds of venture capital financing

A long stream of research has documented the positive effects that patents bring about to emerging firms in high technology industries. The general consensus is that patents contribute to firm growth because they confer monopolistic market rights, offer protection from competitors, increase the negotiating position of patent holders and other benefits. What has received relatively less attention in the literature is whether patents act as a signal that attracts investors such as venture capital firms. The handful of studies that have addressed that question has not analyzed whether the signaling function of patents decreases after the initial attraction of venture capital, as information asymmetries between investors and target firms reduce. In this study we hypothesize that patent activity has a signaling value that diminishes once information asymmetries between investors and funded firms lessen. To study our proposition we draw upon a longitudinal dataset of more than 580 U.S.-based biotechnology firms to empirically demonstrate that biotechnology firms that have submitted patent applications substantially increase the level of funding they receive for their first round of financing. In line with a reduction of information asymmetries once the initial investment has materialized, patent applications and granted patents have no effect on the growth of venture capital funds raised during the second round of financing. We conclude the study with a discussion of avenues for new research, implications for policy makers that consider the usefulness of the current patent system and with insights that can be employed by managers of firms in knowledge intensive areas such as biotechnology.     

Leading change in reading for young adolescents: what is happening in New Zealand?

Effective school leadership in supporting outcomes for all students is critical. This study focuses on six New Zealand principals as they endeavour to make a difference to reading outcomes for 11 to 13 year-old students. In New Zealand, there are approximately 20% of students who are underachieving in reading. Once they reach the final years of primary schooling, this is the final opportunity to rectify this underachievement before these at-risk students enter secondary schooling. Interviews were conducted with the six principals at six case study schools, which represented a range of schools. Findings showed that there was widespread use of standardized testing results in reading to provide accountability for the New Zealand National Standards requirement, and also to inform next teaching steps. However, principals differed in the manner that they led the schools-wide analyses of the data. There was a stark diversity in the implementation of sustained and focused professional development in reading. The use of teacher aides to support our most vulnerable students, low-progress readers and English Speakers of Second Language was widespread, with only two schools providing in-school support and training of these paraprofessionals.
