EXPLORING FEAR: ROUSSEAU,DEWEY, AND FREIRE ON FEAR AND LEARNING

Fear is not the first feature of educational experience associated with the best‐known progressive educational theorists—Jean‐Jacques Rousseau, John Dewey, and Paolo Freire. But each of these important thinkers did, in fact, have something substantive to say about how fear functions in the processes of learning and growth. Andrea English and Barbara Stengel juxtapose the ideas of these thinkers in this essay for three purposes: (1) to demonstrate that there is a progressive tradition that accounts for negative emotion in learning; (2) to explore doubt, discomfort, and difficulty as pedagogically useful, with links to fear as both a prompt for and an impediment to growth; and (3) to suggest that teachers take negative affect into account in their pedagogical practice. In doing so, English and Stengel join with contemporary theorists in and out of education to recognize that affect cannot be left out of social theory and that understanding the play of emotion is an integral part of creating truly educational contexts and experiences. The authors' focus here is on fear in processes of learning.     

Leading Developmental Peer Observation of Teaching in Higher Education: Perspectives from Australia and England

Whilst peer observation of teaching is well established as a practice that can enhance teaching quality, the challenge to fully embed this practice in universities remains unresolved. This article analyses the perspectives of 18 university leaders (nine Australian and nine English) drawn from a range of school-based leaders to senior leaders of learning and teaching. Our study indicates that some of the challenges associated with leading such schemes can be mitigated through approaches to educational leadership that enact a respectful and collegiate ethos. This we suggest can support developmental academic engagement in peer observation for positive and lasting change.     

Bioimpedance patterns and bioelectrical impedance vector analysis (BIVA) of road cyclists

Bioelectrical impedance vector-analysis (BIVA) describes cell-mass, cell function and hydration status of an individual or a group. The goal of the present investigation was to provide bioelectrical impedance data for 525 male road cyclists (155 professionals, 79 elite, 59 elite-youth, and 232 amateurs) at the time of their optimal performance level. Data were plotted on the resistance-reactance (R-Xc) graph to characterize cyclists group vectors using BIVA. Compared to the general male population, the mean vector position of the road cyclists indicates a higher body cell mass (BCM) and phase angle (p<0.001). The vector position of the high-performance, compared to the amateur cyclists showed similar patterns with higher BCM and phase angles and higher reactance values for the high-performance athletes (p<0.001). The bio-impedance data were used to calculate the 50%, 75%, and 95% tolerance ellipses of each group of cyclists. The characteristic vector positions of the road cyclists indicate normal hydration and greater muscle mass and function of the high-performance cyclists compared to amateur cyclists and the normal population. The cyclists specific tolerance ellipses, particularly the high-performance cyclists might be used for classifying a cyclist according to the individual vector position and to define target vector regions for lower level cyclists.     

Relationship between performance-based and laboratory tests for lower-limb muscle strength and power assessment in healthy older women

Abstract

The aim of the study was to assess the relationship between performance-based and laboratory tests for muscular strength and power assessment in older women. Thirty-two women aged 68.8 ± 2.8 years were recruited. All participants were asessed for: (a) two performance-based tests – the box-stepping test (mean 296 ± 51 J) and two-revolution maximum test (mean 7.1 ± 2 kg) performed while pedalling on a cycle ergometer; and (b) muscular function tests – maximal instantaneous peak power jumping on a force platform (mean 1528 ± 279 W); maximal voluntary contraction (MVC) during knee extension (mean 601 ± 571 N) and leg press (mean 626 ± 126 N), and leg press power (mean 483 ± 98 W) on a dynamometer. Using univariate analysis, performance-based tests were compared with laboratory muscle strength and power measurements. Muscle power correlated most strongly with the performance-based tests for both jumping and leg press power (r-values between 0.67 and 0.75; P < 0.01). The correlation with muscle strength measures ranged between 0.48 and 0.61 (P < 0.01). The proposed tests may have particular relevance in geriatric and rehabilitation environments as they represent an easy, practical, and inexpensive alternative for the assessment of muscular strength and power.     

Throwing performance in water polo is related to in-water shoulder proprioception

ABSTRACT

Water polo players require a high level of upper-extremity strength, flexibility and coordination to achieve a peak level of throwing performance. Increased levels of shoulder proprioceptive acuity, strength and range of motion (ROM) have been previously associated with higher sporting performance. A coach-rating scale, used to quantify an athlete’s kicking proficiency in soccer; was adapted in the current study to measure each coach’s subjective expert opinion regarding athletes’ throwing mechanics, velocity, and accuracy. To examine this hypothesis shoulder proprioception acuity of 18 water polo players was measured both in-water and on-land using an AMEDA apparatus and correlated with coach-rated throwing performance and clinical measures of shoulder strength and ROM. There was a moderate positive correlation between the in-water and the on-land proprioception acuity (r = 0.47, p < 0.05). The in-water score showing a strong positive correlation with coach rated throwing mechanics (r = 0.68, p < 0.05) and velocity (r = 0.75, p = 0.02), suggesting that superior proprioception acuity contributed to fast, mechanically-efficient throwing. These findings support the notion that in-water proprioceptive acuity is an important determinant of the throwing performance achieved by water polo athletes and its measurement may be a valuable adjunct to current athlete screening.     

A Critical Analysis of Current Indexes for Digital Divide Measurement

Several composite indexes grouping several variables into a single figure have been proposed for measuring the digital divide. In this article, the authors analyze shortcomings of extant indexes. Using multivariate analysis tools, they show that in the definition of composite indexes it is possible to individuate a limited set of more influencing and significant variables. This finding suggests the possibility of replacing some redundant variables with other dimensions that include other aspects of the digital divide that are not considered in extant measures.     

Innovation and firm value: An investigation of the changing role of patents, 1985–2007

This paper examines how the relationship between firm value and patent-based indicators of inventive activity has changed over time. We use data from more than 33,000 mergers and acquisitions deals between 1985 and 2007, and distinguish between American (USPTO) and European (EPO) patents. Our results indicate that over time EPO patents have become the dominant indicator of innovative activity, while USPTO patents have no effect on firm value near the end of the sample period. The results are robust to controlling for citations and are especially strong for small firms, for firms operating in the drug and chemical industries, and when target and acquiring firms operate in different industries or countries.     

Chemical apathy or hysteria: What role for education?

Emotional responses from local community groups to the establishment of new industrial activities, involving toxic chemicals, are common. The need for more public education about chemical hazards has often been stated. In the eastern suburbs of Melbourne, PCBs have been stored since 1985, pending their destruction. Council approval for the siting of a pilot plant for their treatment recently caused controversy. This paper presents an analysis of the situation, defines the knowledge needed by ordinary people to participate effectively and rationally in decision making and discusses the acquisition of that knowledge in a community setting. It is not the intention of the author to discuss the contribution that could be made through formal secondary education. Specializations: primary science teacher education, computers in education, environmental education, social responsibility in science.     

Young learners: mapping the beliefs and practices of preschool teachers in relation to early literacy development

This paper introduces the Young Learners?? Project, which is a large scale longitudinal study that aims to identify a number of factors associated with positive outcomes in literacy in the first year of school: the role of the preschool teacher, home life and child characteristics. In particular, it presents the design of one sub-study within the larger project that is focusing on the beliefs, theoretical constructs and literacy practices of 25 preschool teachers. The paper deliberates the methodological choices of a group of researchers who set out to represent in diverse ways, and for diverse purposes, the layered meanings inherent in preschool teachers?? beliefs and practices in relation to early literacy development. In particular, through reference to illustrative extracts of a single case analysis, the paper explores the possibilities and complexities of adopting mixed methods and in doing so, responds to a call for researchers to make explicit the purposes and challenges of case study methodologies.
