Research as an intercultural ‘contact zone’

Contemporary researchers need to work across many cultural boundaries between ethnicities, between disciplines, between universities and industry, between professional cultures, and between various workplace cultures. While many authors have sought to characterise aspects of this boundary work, there remains little research on how researchers, especially research higher degree students, might be adequately prepared to work sensitively in these cultural borderlands. This article draws upon the post-colonial concept of the ‘contact zone’ to reconceptualise the knowledge and skills required by the successful intercultural researcher. It demonstrates how recognition of and engagement with cultural difference can create deconstructive, productive possibilities for innovative research and new knowledge. The article also examines the consequences of a lack of intercultural sensitivity and equity – the symbolic violence and exploitation present in the contemporary research arena. This recasting of research has significant implications for future research training.     

Auditory Sensitivity,Speech Perception,and Reading Development and Impairment

While the importance of phonological sensitivity for understanding reading acquisition and impairment across orthographies is well documented, what underlies deficits in phonological sensitivity is not well understood. Some researchers have argued that speech perception underlies variability in phonological representations. Others have investigated the role of more general auditory sensitivity for reading development and reading difficulties, arguing that poor phonological representations may actually be due to broad underlying auditory deficits, which are not restricted to speech stimuli. We argue that these hypotheses are not necessarily mutually exclusive. In this review, we demonstrate that auditory sensitivity and speech perception can be integrated into a single developmental model, in which auditory sensitivity may have an indirect impact on reading; this impact is mediated by speech perception. In the model, we distinguish general auditory sensitivity as falling into at least two general categories: rhythmic and temporal. Correspondingly, speech perception itself can be distinguished as suprasegmental and segmental. Theoretically, the proposed model integrates a broad range of studies on general auditory and speech perception to suggest a developmental trajectory for reading acquisition that can be explored from before birth. Practically, the proposed model points to different ways of understanding and diagnosing reading difficulties and distinguishing reading difficulties across languages and orthographies.     

The role of injection cues in the production of the morphine preexposure effect in taste aversion learning

The attenuation of an LiCl-induced conditioned taste aversion (CTA) by LiCl preexposure is mediated primarily by associative blocking via injection-related cues. Given that preexposure to morphine attenuates morphine-induced CTAs, it was of interest to determine whether injection cues also mediate this effect. Certain morphine-induced behaviors such as analgesic tolerance are controlled associatively, via injection-related cues. Accordingly, animals in the present experiments were preexposed to morphine (or vehicle) every other day for five total exposures, followed by an extinction phase, in which the subjects were given saline injections (or no treatment) for 8 (Experiment 1) or 16 (Experiment 2) consecutive days. All of the animals then received five CTA trials with morphine (or vehicle). The morphine-preexposed animals in Experiment 1 displayed an attenuation of the morphine CTA that was unaffected by extinction saline injections, suggesting that blocking by injection cues during morphine preexposure does not mediate this effect. All of the morphine-preexposed subjects in Experiment 2 displayed a weakened preexposure effect, an effect inconsistent with a selective extinction of drug-associated stimuli. The attenuating effects of morphine preexposure in aversion learning are most likely controlled by nonassociative mechanisms, like drug tolerance.     

Shaping a culture: oral histories of academic development in Australian universities

Academic development has had an approximately forty‐year history within Australian higher education, paralleling the major expansions and changes in the sector, both nationally and internationally. Its principal concerns have been the improvement of teaching and the professional development of the academics who teach. The history of academic development has gone largely undocumented and unexamined at a national level, in Australia and elsewhere. However, as university teaching has increasingly become important in relation to quality in higher education, academic development has become a central player in the work of universities. It becomes of particular importance at this time to garner a more thorough understanding of the continuities as well as the discontinuities in the meanings and practices of university teaching and in the work of those whose role has been to support its development. This article presents a discussion of two key themes identified from a set of oral history interviews conducted with early leaders in academic development in Australia. These themes offer different insights into issues and understandings of academic development in today’s university. The first concerns a perennial issue in academic development – the struggle to define academic development’s emerging ethos in relation to research and service to the broader university’s endeavour. The second theme represents an issue that has been forgotten or marginalised in the official accounts of academic development but which lives on in the ‘lore’ of the field – the role of activism in the shaping of university teaching and academic development.     

Social responsibility and community development: Lessons from the Sistema de Aprendizaje Tutorial in Honduras

This article extends understanding of the connections between education, social capital, and development through a mixed-methods case study of the Sistema de Aprendizaje Tutorial, or SAT¹, an innovative secondary-level education system. The quantitative dimension of the research used survey measures of social responsibility to compare 93 SAT students to 88 other students in conventional Honduran schools, with samples based on the naturally occurring (non-random) presence of one of these two different educational programs in each of nine nearby Honduran communities. Preliminary findings suggest that students in the SAT program held a greater sense of social responsibility than their peers in conventional schools. Students’ statements about their own educational experiences were analyzed in order to identify some of the characteristics of the SAT program that may have led to this difference. The SAT approach to developing social responsibility is contrasted to a human rights focused approach.     

Larger strength losses and muscle activation deficits in plantar flexors induced by backward downhill in reference to distance-matched forward uphill treadmill walk

We tested the hypothesis that backward downhill walking (eccentric component) impairs both voluntary activation and muscle contractile properties in the plantar flexors and delays recovery as compared to a gradient and distance-matched uphill walk. Fourteen males performed two 30-min walking exercises (velocity: 1?m/?s; grade: 25%; load: 12% of body weight), one downhill (DW) and one uphill (UP), in a counterbalanced order, separated by 6?weeks. Neuromuscular test sessions were performed before, after, 24-, 48- and 72-h post-exercise, including motor nerve stimulations during brief (5?s) and sustained (1?min) maximal isometric voluntary contractions of the plantar flexors. DW (?18.1?±?11.1%, P?P?=.15), decreased torque production during brief contractions for at least three days post-exercise (P?P?P?=?.024) and DW (?25.6?±?10.3%, P?P?=?.001) was lower in DW than UP. Peak twitch torque and maximum rates of torque development and relaxation were equally reduced after UP and DW (P?P?P?>?.05). Using a direct comparison, the capacity to drive the plantar flexors during sustained contractions remains sub-optimal during the three-day recovery period in response to non-exhaustive, downhill backward walking in reference to an uphill exercise matched for distance covered.     

Differences between motion capture and video analysis systems in calculating knee angles in elite-standard race walking

Race walking is an event where the knee must be straightened from first contact with the ground until midstance. The aim of this study was to compare knee angle measurements between 2D videography and 3D optoelectronic systems. Passive retroreflective markers were placed on the right leg of 12 race walkers and 3D marker coordinate data captured (250 Hz), with 2D video data (100 Hz) recorded simultaneously. Knee angle data were first derived based on the markers’ coordinates, and separately by using a 3D model that also incorporated thigh and shank clusters; the video data were analysed using both automatic tracking and manual digitising, creating four conditions overall. Differences were calculated between conditions for stance (using root mean square values), and at discrete events. There were few differences between systems, although the 3D model produced larger angles at midstance than using automatic tracking and marker coordinates (by 3 – 6°, P < 0.05). These differences might have occurred because of how the 3D model locates the hip joint, and because of the addition of marker clusters. 2D videography gave similar results to the 3D model when using manual digitising, as it allowed for errors caused by skin movement to be corrected.     

Effects of a Mindfulness-Based Intervention on the Perception of Basic Psychological Need Satisfaction among Special Education Students

Mindfulness-Based Interventions (MBIs) have been increasingly implemented in schools to foster better emotional regulation skills for students with special education needs such as learning disabilities (LDs). This pilot study aimed to evaluate the impact of a MBI on the need satisfaction of elementary students with severe LDs. A prospective quasi-experimental design involving one group and two time points was employed. A sample of 14 elementary school students from a severe LDs special education class participated in this project. Repeated-measures ANOVAs were conducted and revealed a significant reduction in need satisfaction, with a large effect size (η² = .35). Contrary to our hypothesis, the MBI appeared to be negatively related to need satisfaction among participants. These results indicate that MBIs could be linked with better self-evaluation skills in students with severe LDs, which, in turn, may change (or increase the accuracy of) the perception that children have of their own need satisfaction.     

The Role of Orthographic and Semantic Learning in Word Reading and Reading Comprehension

We tested the theoretically driven hypotheses that children’s orthographic and semantic learning are associated with their word reading and reading comprehension skills, even when orthographic and semantic knowledge are taken into account. A sample of 139 English-speaking Grade 3 children completed a learning task in which they read stories about new inventions. Then they were tested on their learning of the spelling and meaning of the inventions (i.e., orthographic and semantic learning, respectively). Word reading and reading comprehension were assessed with standardised tasks, and orthographic and semantic knowledge were assessed with choice tasks targeting the spelling and meaning of existing words. The results of our structural equation modeling indicated that orthographic learning predicted word reading directly and reading comprehension indirectly via word reading. We also found that semantic learning predicted reading comprehension directly. These findings support integration of the self-teaching hypothesis and the lexical quality hypothesis.
