Sweat lactate response during cycling at 30°C and 18°C WBGT

Sweat lactate reflects eccrine gland metabolism. However, the metabolic tendencies of eccrine glands in a hot versus thermoneutral environment are not well understood. Sixteen male volunteers completed a maximal cycling trial and two 60-min cycling trials [30°C?=?30±1°C and 18°C?=?18±1°C wet bulb globe temperature (WBGT)]. The participants were requested to maintain a cadence of 60 rev?·?min^?1 with the intensity individualized at ～ 90% of the ventilatory threshold. Sweat samples at 10, 20, 30, 40, 50 and 60?min were analysed for lactate concentration. Sweat rate at 30°C (1380±325?ml?·?h^?1) was significantly greater (P<0.05) than at 18°C (632±311?ml?·?h^?1). Sweat lactate concentration was significantly greater (P<0.05) at each time point during the 18°C trial, with values between trials tending to converge across time. During the 30°C trial, both heart rate (20, 30, 40, 50 and 60?min) and rectal temperature (30, 40, 50 and 60?min) were significantly higher than in the 18°C trial. Higher sweat lactate concentrations coupled with lower sweat rates may indicate a greater relative contribution of oxygen-independent metabolism within eccrine glands during exercise at 18°C. Decreases in sweat lactate concentration across time suggest either greater dilution due to greater sweat volume or increased reliance on aerobic metabolism within eccrine glands. The convergence of lactate concentrations between trials may indicate that time-dependent modifications in sweat gland metabolism occur at different rates contingent partially on environmental conditions.     

Computer Science in Liberal Arts Colleges

When a liberal arts college decides to include computer science as one of its academic disciplines, a number of questions arise. What is an appropriate curriculum? What sort of laboratory support does this new discipline need? How does a small liberal arts school attract, retain, and evaluate faculty in this area? Do computer science faculty become a separate department or remain joined with mathematics or some other discipline? In short, what must be done to put computer science on equal footing with mathematics and other scientific disciplines? This paper addresses these questions.     

The architecture of peer assessment: do academically successful students make good teammates in design assignments?

This paper considers the relationship between architecture and construction management students’ overall academic abilities (as measured by Weighted Average Marks [WAMs]), their peer ratings for contributions to team design assignments (as measured by an online Self-and-Peer-Assessment [SAPA] tool), and their specific abilities as building designers (as measured by grades in individual design assignments). The research was conducted to determine whether a student’s prior academic achievements might indicate how well they will work in teams. The research demonstrates a statistically significant relationship between WAMs and SAPA ratings indicating that academically successful students more often than not make good teammates. However, the study also highlights that when peers are assessing contributions to teamwork they are assessing skills and qualities in their teammates other than overall academic ability or the ability to design well. Whilst this study is largely located within the field of design, the findings are relevant to any group work where teachers aim to design assessment that unravels group and individual contribution.     

Harambee: Working Together to Engender Change in Communities of Color

Working with communities of color to find solutions to the problems they face is a complex and challenging task. The “It Takes a Village” concept and the Transtheoretical Model of Change (Prochaska, Norcross, and DiClemente 1994) were used by the authors of this article in their work to empower clients of color to effect change in their communities. The narratives by these authors, European-American and African-American practitioners and educators, incorporate accounts of advocacy and social justice initiatives as they describe their interactions with grassroots organizations, such as educational and faith-based institutions, within communities of color.     

Contextually Based Professional Development

In this article, the authors detail a study of a three-year professional development project designed to increase in-service teachers’ classroom technology integration. Participants engaged in learning activities that modeled technology integration from a contextually based perspective that included technology, and pedagogical and content knowledge. Although participants reported having very limited technology skills before professional development began, after two years they reported a significant increase in using technology skills. In addition, participants reported increased comfort and confidence in using technology to the level where they changed their teaching practice to integrate technology. Indeed, between years two and three, participants reported a significant increase in technology use for learning by their students.     

‘Wounded memory’, post-war gender conflict and narrative identity: reinterpreting Reggio Emilia Schools’ origin stories

In this article, memory is examined as it relates to origin stories of the Reggio Emilia approach – an internationally renowned Italian education programme – and to the articulation of women’s experiences of gender and their narrative identity in this very particular context. The article shows that a number of women who partook in the founding of the Reggio Emilia schools suffer from what Ricoeur terms ‘wounded memory’, which occurs when public recognition and legitimisation of one’s own narrative is actively marginalised, suppressed or erased in historical, official and institutional accounts. The author describes this experience and feeling shared by the Reggio Emilia women who were interviewed and argues that this ‘wounded memory’ can be linked to a wider concern with gender inequality. The article concludes by presenting some of the missing accounts of leadership, creativity and initiative that were gathered among these women whose memory has been wounded.     

Getting old and heading south: the academic success of Southerner learners in design cohorts

This paper investigates the relationship between learning style, as determined by Kolb's Learning Style Inventory, age and one measure of academic performance in design assignments for two cohorts of first‐ and third‐year architecture students. The paper focuses on the results of a cross‐curriculum learning style survey conducted as part of a project aimed at resolving the learning difficulties of students collaborating in multi‐disciplinary and multi‐cultural team assignments. The research was conducted to determine how learning style differences in heterogeneous teams might be addressed through pedagogy. In light of evidence in student cohorts of learning style changes towards the learning styles of design teachers as students progress through their studies, this paper demonstrates how these changes reflect a statistically significant relationship between learning styles and academic performance in design assignments.     

Assessing school supports for ELL students using the ECLS-K

Using a large and nationally representative sample of children, this study examined the association between the school resources available to English Language Learners and their academic trajectories from kindergarten through fifth grade. Particular attention was paid to the differences in services provided by schools with high, low, or no ELL student concentrations. Growth-curve modeling results indicated that ELL children started kindergarten with significantly lower reading and math scores compared to their English-speaking peers. However, ELL children improved their math scores fast enough that they were able to narrow the initial gap in math scores with their English-speaking peers by fifth grade. This was particularly true for ELL children in schools with either a high- or low ELL student concentration. In contrast, ELL children still had lower reading scores by fifth grade compared to their English-speaking peers. The results highlight the importance of school resources and services in improving ELL students’ academic trajectories. Directions for future studies are discussed.
