The effect of letter spacing and coloured overlays on reading speed and accuracy in adult dyslexia

Background. Zorzi et al. (2012, Proc. Natl. Acad. Sci. U.S.A., 109, 11455) found evidence that extra-large letter spacing aids children with dyslexia, but the evidence for the coloured overlays is contradictory (e.g., Henderson et al., 2013, J. Res. Special Educ. Needs, 13, 57; Wilkins, 2002, Ophthalmic Physiol. Opt., 22, 448), and possible combined advantages have not been identified. Aims. To investigate whether extra-large letter spacing or coloured overlays can alleviate reading problems in dyslexic adults. Sample. The participants were 24 dyslexic and 24 non-dyslexic university students, matched for age and fluid intelligence. Methods. The reading speed and the errors made by a dyslexic and a control group were measured in four conditions: with and without coloured overlays and with normally and largely spaced texts. Results. Large letter spacing improves the reading speed in general, as well as improves the reading accuracy in dyslexic readers. Conclusions. The results support the positive effect of letter spacing on reading performance

Faculty Perspectives of Academic Integrity During COVID-19: A Mixed Methods Study of Four Canadian Universities

Faculty members are crucial partners in promoting academic integrity at Canadian universities, but their needs related to academic integrity are neither well documented nor understood. To address this gap, we developed a mixed methods survey to gather faculty perceptions of facilitators and barriers to using the existing academic integrity procedures, policies, resources, and supports required to promote academic integrity. In this article, we report the data collected from 330 participants at four Canadian universities. Responses pointed to the importance of individual factors, such as duty to promote academic integrity, as well as contextual factors, such as teaching load, class size, class format, availability of teaching assistant support, and consistency of policies and procedures, in supporting or hindering academic integrity. We also situated these results within a micro (individual), meso (departmental), macro (institutional), and mega (community) framework. Results from this study contribute to the growing body of empirical evidence about faculty perspectives on academic integrity in Canadian higher education and can inform the continued development of existing academic integrity supports at universities.Les membres du corps professoral sont des partenaires essentiels dans la promotion de l’intégrité académique dans les universités canadiennes. Toutefois, leurs besoins en cette matière ne sont ni bien documentés ni bien compris. Afin de combler cette lacune, nous avons recueilli, grâce à une méthode de recherche mixte, les perceptions des professeurs quant aux obstacles et aux facilitateurs en lien avec l’utilisation des procédures, politiques, ressources et services de soutien pour la promotion de l’intégritéacadémique. Dans cet article, nous rapportons les données recueillies auprès de 330 participants dans quatre universités canadiennes. Les réponses soulignent l’importance des facteurs individuels tels que le devoir de promouvoir l’intégrité académique. De plus, des facteurs contextuels tels que la charge d’enseignement, la taille et le format de la classe, la disponibilité du soutien  d’assistants d’enseignement et la cohérence des politiques et des procédures peuvent soutenir ou entraver l’intégrité académique. Nous avons également situé ces résultats dans un cadre micro (individuel), méso (départemental), macro (institutionnel) et méga (communautaire). Les résultats de cette étude contribuent à mettre en lumière les perspectives des professeurs sur l’intégrité académiquedans l’enseignement supérieur canadien. Ils peuvent également donner un aperçu des besoins en développement professionnel et du soutien nécessaire dans les universités

Associations of depression status and hopelessness with breast cancer.

This study extended the literature by examining whether three profiles of depression predicted breast cancer status. In 1076 women of the Baltimore Epidemiologic Catchment Area study, depression status and hopelessness were measured at baseline and breast cancer status was ascertained 24 years later. Double depression, but not major depression or dysthymia, was associated with breast cancer. Hopelessness predicted fewer new cases of breast cancer. When double depression and hopelessness were simultaneously entered as predictors, the regression weights of both predictors increased. The role of severe and extended duration depression as well as possible explanations for unexpected findings are discussed

Differences in Rate of Perceived Exertion and Workload Intensity in Males and Females during Submaximal Arm and Leg Ergometry

International Journal of Exercise Science 15(4): 1222-1235, 2022. Purpose: Arm ergometry (AE) is necessitated for individuals unable to perform leg ergometry (LE) exercise. This study explored gender differences in RPE and workload (WL) during AE and LE at submaximal target heart rates (THR). Methods: 35 healthy college-aged individuals were randomly allocated to begin exercise on either AE or LE. Participants exercised on both modes with increasing WL to achieve submaximal THRs of 110, 120, 130, 140 and 150 beats per minute (bpm). Factorial ANOVAs tested for differences in RPE and WL. Results: No significant differences were found in RPE between genders, as well as between arm and leg exercise (p \u3e 0.001). For WL, a significant main effect was found for mode with LE greater than AE (p \u3c 0.001), and gender, with males greater than females (p \u3c 0.001). A significant interaction effect was also found for HR and mode, with a greater increase in WL during LE compared to AE in both genders (p = 0.001). Conclusions: Exercise specialists typically prescribe exercise based on a chosen THR. The results of this study provide meaningful data on mean RPE and WL responses that a given THR elicits for ergometry. The finding of no differences in RPE between AE and LE informs the clinician that at any given submaximal THR, similar RPE scores can be expected during AE and LE. Further research is warranted to investigate differences in wider populations

Evaluation of alternatives for two-dimensional linear cascade facilities

This paper presents two low-cost alternatives for turbine blade surface heat transfer and fluid dynamics measurements. These models embody careful compromises between typical academic and full-scale turbomachinery experiments and represent a comprehensive strategy to develop experiments that can directly test shortcomings in current turbomachinery simulation tools. A full contextual history of the wide range of approaches to simulate turbine flow conditions is presented, along with a discussion of their deficiencies. Both models are simplifications of a linear cascade: the current standard for simulating two-dimensional turbine blade geometries. A single passage model is presented as a curved duct consisting of two half-blade geometries, carefully designed inlet and exit walls and inlet suction. This facility was determined to be best suited for heat transfer measurements where minimal surface conduction losses are necessary to allow accurate numerical model replication. A double passage model is defined as a single blade with two precisely designed outer walls, which is most appropriate for flow measurements. The design procedures necessary to achieve a desired flow condition are discussed

Academic Integrity Policy Analysis of Publicly-Funded Universities in Ontario, Canada: A Focus on Contract Cheating

In this article we report findings from a review of universities’ academic integrity policies in Ontario, Canada. The research team systematically extracted, reviewed, and evaluated information from policy documents in an effort to understand how these documents described contract cheating in Ontario universities (n = 21). In all, 23 policies were examined for contract cheating language. The elements of access, approach, responsibility, detail, and support were examined and critiqued. Additionally, document type, document title and concept(s), specific contract cheating language, presence of contract cheating definitions and policy principles were reviewed. Findings revealed that none of the universities’ policies met all of the core elements of exemplary policy, were reviewed and revised with less frequency than their college counterparts, lacked language specific to contract cheating, and were more frequently focused on punitive rather than educative approaches. These findings confirm that there is further opportunity for policy development related to the promotion of academic integrity and the prevention of contract cheating.

Hail formation triggers rapid ash aggregation in volcanic plumes.

During explosive eruptions, airborne particles collide and stick together, accelerating the fallout of volcanic ash and climate-forcing aerosols. This aggregation process remains a major source of uncertainty both in ash dispersal forecasting and interpretation of eruptions from the geological record. Here we illuminate the mechanisms and timescales of particle aggregation from a well-characterized 'wet' eruption. The 2009 eruption of Redoubt Volcano, Alaska, incorporated water from the surface (in this case, a glacier), which is a common occurrence during explosive volcanism worldwide. Observations from C-band weather radar, fall deposits and numerical modelling demonstrate that hail-forming processes in the eruption plume triggered aggregation of ∼95% of the fine ash and stripped much of the erupted mass out of the atmosphere within 30 min. Based on these findings, we propose a mechanism of hail-like ash aggregation that contributes to the anomalously rapid fallout of fine ash and occurrence of concentrically layered aggregates in volcanic deposits.AVE acknowledges NSF Postdoctoral Fellowship EAR1250029 and a seed grant from NASA Ames Supercomputing Center.

Improving access to psychological therapies (IAPT) for people with bipolar disorder:summary of outcomes from the IAPT demonstration site

Access to structured psychological therapy recommended for bipolar disorder (BD) is poor. The UK NHS Improving Access to Psychological Therapies initiative commissioned a demonstration site for BD to explore the outcomes of routine delivery of psychological therapy in clinical practice, which this report summarises. All clinically diagnosed patients with BD who wanted a psychological intervention and were not in acute mood episode were eligible. Patients were offered a 10-session group intervention (Mood on Track) which delivered NICE congruent care. Outcomes were evaluated using an open (uncontrolled), pre-post design. Access to psychological therapy increased compared to preceding 6 years by 54%. 202 people began treatment; 81% completed >5 sessions; median 9 sessions (range 6–11). Pre-post outcomes included personal recovery (primary outcome), quality of life, work and social functioning, mood and anxiety symptoms (secondary outcomes). Personal recovery significantly improved from pre to post-therapy; medium effect-size (d = 0.52). Secondary outcomes all improved (except mania symptoms) with smaller effect sizes (d = . 20–0.39). Patient satisfaction was high. Use of crisis services, and acute admissions were reduced compared to pre-treatment. It is possible to deliver group psychological therapy for bipolar disorder in a routine NHS setting. Improvements were observed in personal recovery, symptoms and wider functioning with high patient satisfaction and reduced service use

Living on the edge: forest edge effects on microclimate and terrestrial mammal activity in disturbed lowland forest in Sumatra, Indonesia

Species–environment relationships are often studied at large spatial scales, but effective conservation requires an understanding of local-scale environmental drivers and pressures. Widespread degradation and fragmentation of forests have increased the proportion of tropical mammal habitat that is affected by edge effects. Edge effects include greater exposure to anthropogenic disturbance and abiotic changes that synergistically influence how well populations can cope with climate change. We investigated relationships between distance to the forest edge, forest structure, microclimate and terrestrial mammal detections in a selectively logged forest at the boundary of Gunung Leuser National Park in Sumatra, Indonesia. We collected mammal detection data from motion-activated camera traps, microclimate data from automated climate data loggers and forest structure data from vegetation plots. Daily mean and maximum temperatures significantly decreased with distance from the forest edge, whereas tree height and minimum temperature increased. Mammal diversity was lower at the forest edge compared to the interior. Mammals were detected less frequently at the forest edge, although this relationship varied between mammal orders. Mammal detections were best explained by temperature, tree height and tree diameter at breast height. These results demonstrate that abiotic changes in forests brought on by edge effects have negative impacts on mammals, but these effects vary between mammal taxa because of differing sensitivities to human disturbance. Our findings highlight the importance of considering local-scale environmental drivers in determining species–environment relationships to identify key habitat features such as microclimate refuges that should be prioritized in ecosystem management
