A systematic review and synthesis of qualitative research: the influence of school context on symptoms of attention deficit hyperactivity disorder

This systematic review and synthesis of qualitative research explored contextual factors relevant to non-pharmacological interventions for attention deficit hyperactivity disorder (ADHD) in schools. We conducted meta-ethnography to synthesise 34 studies, using theories of stigma to further develop the synthesis. Studies suggested that the classroom context requiring pupils to sit still, be quiet and concentrate could trigger symptoms of ADHD, and that symptoms could then be exacerbated through informal/formal labelling and stigma, damaged self-perceptions and resulting poor relationships with staff and pupils. Influences of the school context on symptoms of ADHD were often invisible to teachers and pupils, with most attributions made to the individual pupil and/or the pupil’s family. We theorise that this ‘invisibility’ is at least partly an artefact of stigma, and that the potential for stigma for ADHD to seem ‘natural and right’ in the context of schools needs to be taken into account when planning any intervention.     

Exploring features of highly productive research contexts in Asia: a comparison of knowledge production in educational leadership in Israel and Hong Kong

A recent review of research identified two Asian societies that represented “positive outliers” in the production of published knowledge on educational leadership and management: Hong Kong and Israel. These were the only Asian societies that had produced a critical mass of publications in this field in international journals over the past two decades. The current study examined the nature of the publication corpus from Hong Kong and Israel in an effort to understand factors that may have contributed to this capacity for high research productivity. The results suggested that different strategies may have accounted for research capacity development in these two societies. Directions are identified for future research.     

Identification-Based Multiple-Choice Assessments in Anatomy can be as Reliable and Challenging as Their Free-Response Equivalents

Multiple-choice (MC) anatomy “spot-tests” (identification-based assessments on tagged cadaveric specimens) offer a practical alternative to traditional free-response (FR) spot-tests. Conversion of the two spot-tests in an upper limb musculoskeletal anatomy unit of study from FR to a novel MC format, where one of five tagged structures on a specimen was the answer to each question, provided a unique opportunity to assess the comparative validity and reliability of FR- and MC-formatted spot-tests and the impact on student performance following the change of test format to MC. Three successive year cohorts of health science students (n = 1,442) were each assessed by spot-tests formatted as FR (first cohort) or MC (following two cohorts). Comparative question difficulty was assessed independently by three examiners. There were more higher-order cognitive skill questions and more of the course objectives tested in the MC-formatted tests. Spot-test reliability was maintained with Cronbach’s alpha reliability coefficients ≥ 0.80 and 80% of the MC items of high quality (having point-biserial correlation coefficients > 0.25). These results also demonstrated guessing was not an issue. The mean final score for the MC-formatted cohorts increased by 4.9%, but did not change for the final theory examination that was common to all three cohorts. Subgroup analysis revealed that the greatest change in spot-test marks was for the lower-performing students. In conclusion, our results indicate spot-tests formatted as MC are suitable alternatives to FR tests. The increase in mean scores for the MC-formatted spot-tests was attributed to the lower demand of the MC format.     

Need for Cognition as a Mediating Variable Between Aggressive Communication Traits and Tolerance for Disagreement

This study examined the need for cognition as a mediator between aggressive communication traits and tolerance for disagreement. Previous research suggests that argumentativeness is a positive predictor of tolerance for disagreement, while verbal aggressiveness is a negative predictor of tolerance for disagreement. Our findings indicate that need for cognition positively mediates the relationship between argumentativeness and tolerance for disagreement, as well as verbal aggressiveness and tolerance for disagreement.

Paulo Freire and ‘the need for a kind of education in hope’

This paper explores Paulo Freire’s philosophy of hope. This is significant because, for Freire, it was human hope that rendered education possible, necessary and necessarily political. Like other areas of his thought, however, his reading of hope contained ambiguities and contradictions, and the paper explores these by locating Freire’s thought in the wider context of the philosophy of hope. It focuses in particular on the divergent interpretations Freire provides regarding the objective and the experience of hope. It argues that many of the conflicting demands placed on the radical educator stem from the tensions and vagaries one finds within his philosophy. The paper concludes by discussing the wider significance of Freire in light of the discourse of ‘complex hope’ that is developing within educational studies.     

Process,Orientation, and System: The Pedagogical Operation of Utopia in the Work of Paulo Freire

Recent years have witnessed a renewed interest in utopianism within educational theory. In this essay, Darren Webb explores the utopian pedagogy of Paulo Freire in the context of what one commentator has dubbed “the educational comeback of utopia.” Webb argues that Freire's significance lies in the way he embraced both “utopia as process” and “utopia as system.” This is significant because the contemporary rejuvenation of utopianism has extended only so far, embracing utopia conceived as an open‐ended process of becoming but shying away from utopia conceived as the delineation of a normative vision to be struggled for and won. Webb outlines the pedagogical operation of utopia as process, cognitive‐affective orientation, and system, and he argues that Freire was right in insisting that each is constitutive of effective educational practice.     

A simple and inexpensive enteric-coated capsule for delivery of acid-labile macromolecules to the small intestine

Understanding the ecology of the gastrointestinal tract and the impact of the contents on the host mucosa is emerging as an important area for defining both wellness and susceptibility to disease. Targeted delivery of drugs to treat specific small intestinal disorders such as small bowel bacterial overgrowth and targeting molecules to interrogate or to deliver vaccines to the remote regions of the small intestine has proven difficult. There is an unmet need for methodologies to release probes/drugs to remote regions of the gastrointestinal tract in furthering our understanding of gut health and pathogenesis. In order to address this concern, we need to know how the regional delivery of a surrogate labeled test compound is handled and in turn, if delivered locally as a liquid or powder, the dynamics of its subsequent handling and metabolism. In the studies we report on in this paper, we chose ¹³C sodium acetate (¹³C-acetate), which is a stable isotope probe that once absorbed in the small intestine can be readily measured non-invasively by collection and analysis of ¹³CO₂ in the breath. This would provide information of gastric emptying rates and an indication of the site of release and absorptive capacity. In a series of in vitro and in vivo pig experiments, we assessed the enteric-protective properties of a commercially available polymer EUDRAGIT®L100-55 on gelatin capsules and also on DRcaps®. Test results demonstrated that DRcaps®coated with EUDRAGIT®L100-55 possessed enhanced enteric-protective properties, particularly in vivo. These studies add to the body of knowledge regarding gastric emptying in pigs and also begin the process of gathering specifications for the design of a simple and cost-effective enteric-coated capsule for delivery of acid-labile macromolecules to the small intestine.     

Cycling with noncircular chainring system changes the three-dimensional kinematics of the lower limbs

This study investigated the three-dimensional (3-D) pedaling kinematics using a noncircular chainring system and a conventional system. Five cyclists pedaled at their preferred cadence at a workload of 300 W using two crank systems. Flexion/extension of the hip, knee and ankle as well as shank rotation, foot adduction/abduction, and pedal angle were measured. Joint range of motion (ROM) and angular displacements were compared between the systems. Sagittal plane ROM was significantly greater (P < 0.05) at the hip (noncircular system = 39 ± 3°; conventional system = 34 ± 4°) the knee (noncircular system = 69 ± 4°; conventional system = 57 ± 10°), and ankle (noncircular system = 21 ± 2°; conventional system = 19 ± 4°) resulting in greater pedal ROM (noncircular system = 43 ± 3°; conventional system = 37 ± 5°) while using the noncircular system. Shank rotation ROM was significantly lower (P < 0.05) while using the noncircular chainring (noncircular system = 10 ± 1°; conventional system = 14 ± 1°). These results support a significant effect of the noncircular chainring system on pedaling kinematics during submaximal exercise.     

Computer Simulations Improve University Instructional Laboratories

Laboratory classes are commonplace and essential in biology departments but can sometimes be cumbersome, unreliable, and a drain on time and resources. As university intakes increase, pressure on budgets and staff time can often lead to reduction in practical class provision. Frequently, the ability to use laboratory equipment, mix solutions, and manipulate test animals are essential learning outcomes, and “wet” laboratory classes are thus appropriate. In others, however, interpretation and manipulation of the data are the primary learning outcomes, and here, computer-based simulations can provide a cheaper, easier, and less time- and labor-intensive alternative. We report the evaluation of two computer-based simulations of practical exercises: the first in chromosome analysis, the second in bioinformatics. Simulations can provide significant time savings to students (by a factor of four in our first case study) without affecting learning, as measured by performance in assessment. Moreover, under certain circumstances, performance can be improved by the use of simulations (by 7% in our second case study). We concluded that the introduction of these simulations can significantly enhance student learning where consideration of the learning outcomes indicates that it might be appropriate. In addition, they can offer significant benefits to teaching staff.
