    In this study we assessed the usefulness of a multifaceted teaching framework in an advanced statistics course. We sought to expand on past findings by using this framework to assess changes in anxiety and self-efficacy, and we collected focus group data to ascertain whether students attribute such changes to a multifaceted teaching approach. Statistics anxiety significantly decreased and students' current statistics self-efficacy increased. Further, course performance was positively correlated with self-efficacy and a strong negative relationship between statistics anxiety and self-efficacy was documented. Focus group data suggested students appreciated aspects of this teaching framework and that they thought it served to reduce anxiety. In addition to this teaching framework, two instructional techniques were used to teach two specific statistical concepts. These techniques did not result in significant performance differences; however, students reported enjoying the activities and encouraged their use in future classes. Overall, this study suggests a multifaceted teaching framework may be useful in helping graduate students overcome anxiety and increase self-efficacy when completing an advanced statistics course. The research presented here adds to the growing literature concerning the importance of non-cognitive factors when teaching statistics. Limitations and directions for future research are discussed

    Purpose Cancer-related cognitive impairment (CRCI) is a common, fatigue-related symptom that disrupts cancer survivors’ quality of life. Few interventions for CRCI exist. As part of a randomized pilot study targeting cancer-related fatigue, the effects of mindfulness-based stress reduction (MBSR) on survivors’ cognitive outcomes were investigated. Methods Breast and colorectal cancer survivors (n = 71) with moderate-to-severe fatigue were randomized to MBSR (n = 35) or a fatigue education and support (ES; n = 36) condition. The Attentional Function Index (AFI) and the Stroop test were used to assess survivors’ cognitive function at baseline (T1), after the 8-week intervention period (T2), and 6 months later (T3) using intent-to-treat analysis. Mediation analyses were performed to explore mechanisms of intervention effects on cognitive functioning. Results MBSR participants reported significantly greater improvement on the AFI total score compared to ES participants at T2 (d = 0.83, p = 0.001) and T3 (d = 0.55, p = 0.021). MBSR also significantly outperformed ES on most AFI subscales, although both groups improved over time. MBSR produced greater Stroop accuracy rates relative to ES at T2 (r = 0.340, p = 0.005) and T3 (r = 0.280, p = 0.030), with improved accuracy over time only for the MBSR group. There were no significant differences in Stroop reaction time between groups. Improvements in mindfulness mediated the effect of group (e.g., MBSR vs. ES) on AFI total score at T2 and T3. Conclusions Additional randomized trials with more comprehensive cognitive measures are warranted to definitively assess the efficacy of MBSR for CRCI. Implications for Cancer Survivors This pilot study has important implications for all cancer survivors as it is the first published trial to show that MBSR offers robust and durable improvements in CRCI

    Ultracool Field Brown Dwarf Candidates Selected at 4.5 microns

    We have identified a sample of cool field brown dwarf candidates using IRAC data from the Spitzer Deep, Wide-Field Survey (SDWFS). The candidates were selected from 400,000 SDWFS sources with [4.5] <= 18.5 mag and required to have [3.6]-[4.5] >= 1.5 and [4.5] - [8.0] <= 2.0 on the Vega system. The first color requirement selects objects redder than all but a handful of presently known brown dwarfs with spectral classes later than T7, while the second eliminates 14 probable reddened AGN. Optical detection of 4 of the remaining 18 sources implies they are likely also AGN, leaving 14 brown dwarf candidates. For two of the brightest candidates (SDWFS J143524.44+335334.6 and SDWFS J143222.82+323746.5), the spectral energy distributions including near-infrared detections suggest a spectral class of ~ T8. The proper motion is < 0.25 "/yr, consistent with expectations for a luminosity inferred distance of >70 pc. The reddest brown dwarf candidate (SDWFS J143356.62+351849.2) has [3.6] - [4.5]=2.24 and H - [4.5] > 5.7, redder than any published brown dwarf in these colors, and may be the first example of the elusive Y-dwarf spectral class. Models from Burrows et al. (2003) predict larger numbers of cool brown dwarfs should be found for a Chabrier (2003) mass function. Suppressing the model [4.5] flux by a factor of two, as indicated by previous work, brings the Burrows models and observations into reasonable agreement. The recently launched Wide-field Infrared Survey Explorer (WISE) will probe a volume ~40x larger and should find hundreds of brown dwarfs cooler than T7.Comment: 13 pages, 6 figures, accepted for publication in the June 2010 issue of The Astronomical Journa

    Donning the ‘slow professor’: A feminist action research project

    Get PDF
    Corporatization of Higher Education has introduced new performance measurements as well as an acceleration of academic tasks creating working environments characterised by speed, pressure and stress. This paper discusses findings from a qualitative, feminist participatory action research (PAR) study undertaken by an interdisciplinary team of women academics at a modern, corporate university in England. The study illuminates how corporatized HE erodes faculty autonomy, degrades learning environments, damages professional satisfaction and health. Strategies for resistance and liberation developed through the PAR process are discussed

    Utilizing Technology for Diet and Exercise Change in Complex Chronic Conditions Across Diverse Environments (U-DECIDE): Protocol for a Randomized Controlled Trial

    Get PDF
    BACKGROUND: The metabolic syndrome is common across many complex chronic disease groups. Advances in health technology have provided opportunities to support lifestyle interventions. OBJECTIVE: The purpose of this study is to test the feasibility of a health technology-assisted lifestyle intervention in a patient-led model of care. METHODS: The study is a single-center, 26-week, randomized controlled trial. The setting is specialist kidney and liver disease clinics at a large Australian tertiary hospital. The participants will be adults with a complex chronic condition who are referred for dietetic assessment and display at least one feature of the metabolic syndrome. All participants will receive an individualized assessment and advice on diet quality from a dietitian, a wearable activity monitor, and standard care. Participants randomized to the intervention group will receive access to a suite of health technologies from which to choose, including common base components (text messages) and optional components (online and mobile app–based nutrition information, an online home exercise program, and group-based videoconferencing). Exposure to the optional aspects of the intervention will be patient-led, with participants choosing their preferred level of engagement. The primary outcome will be the feasibility of delivering the program, determined by safety, recruitment rate, retention, exposure uptake, and telehealth adherence. Secondary outcomes will be clinical effectiveness, patient-led goal attainment, treatment fidelity, exposure demand, and participant perceptions. Primary outcome data will be assessed descriptively and secondary outcomes will be assessed using an analysis of covariance. This study will provide evidence on the feasibility of the intervention in a tertiary setting for patients with complex chronic disease exhibiting features of the metabolic syndrome. RESULTS: The study was funded in 2019. Enrollment has commenced and is expected to be completed by June 2022. Data collection and follow up are expected to be completed by December 2022. Results from the analyses based on primary outcomes are expected to be submitted for publication by June 2023. CONCLUSIONS: The study will test the implementation of a health technology–assisted lifestyle intervention in a tertiary outpatient setting for a diverse group of patients with complex chronic conditions. It is novel in that it embeds patient choice into intervention exposure and will inform health service decision-makers in regards to the feasibility of scale and spread of technology-assisted access to care for a broader reach of specialist services.

    Curricular Factors that Unintentionally Affect Learning in a Community-Based Interprofessional Education Program: The Student Perspective

    Get PDF
    Background: The Dalhousie Health Mentors Program (DHMP) is a community-based, pre-licensure interprofessional education initiative that aims to prepare health professional students for collaborative practice in the care of patients with chronic conditions. This program evaluation explores the students’ 1) learning and plans to incorporate skills into future practice; 2) ratings of program content, delivery, and assignments; 3) perspectives of curricular factors that inadvertently acted as barriers to learning; and 4) program improvement suggestions.Methods: All students (N = 745) from the 16 participating health programs were invited to complete an online mixed methods program evaluation survey at the conclusion of the 2012–2013 DHMP. A total of 295 students (40% response rate) responded to the Likert-type questions analyzed using descriptive and non-parametric statistics. Of these students, 204 (69%) provided responses to 10 open-ended questions, which were analyzed thematically.Findings: While the majority of respondents agreed that they achieved the DHMP learning objectives, the mixed-methods approach identified curriculum integration, team composition, and effectiveness of learning assignments as factors that unintentionally acted as barriers to learning, with three key student recommendations for program improvement.Conclusions: Educators and program planners need to be aware that even well-intended learning activities may result in unintended experiences that hamper interprofessional learning

    Reflecting on loss in Papua New Guinea

    Get PDF
    This article takes up the conundrum of conducting anthropological fieldwork with people who claim that they have 'lost their culture,' as is the case with Suau people in the Massim region of Papua New Guinea. But rather than claiming culture loss as a process of dispossession, Suau claim it as a consequence of their own attempts to engage with colonial interests. Suau appear to have responded to missionization and their close proximity to the colonial-era capital by jettisoning many of the practices characteristic of Massim societies, now identified as 'kastom.' The rejection of kastom in order to facilitate their relations with Europeans during colonialism, followed by the mourning for kastom after independence, both invite consideration of a kind of reflexivity that requires action based on the presumed perspective of another

    Randomized Controlled Pilot Trial of Mindfulness-Based Stress Reduction Compared to Psychoeducational Support for Persistently Fatigued Breast and Colorectal Cancer Survivors

    Purpose Cancer-related fatigue (CRF) is a disruptive symptom for many survivors. Despite promising evidence for efficacy of Mindfulness-Based Stress Reduction (MBSR) in reducing CRF, no trials comparing it to an active comparator for fatigued survivors have been published. The purpose of this trial was to compare MBSR to psychoeducation for CRF and associated symptoms. Methods Breast (n=60) and colorectal (n=11) cancer survivors (stage 0–III) with clinically significant CRF after completing chemotherapy and/or radiation therapy an average of 28 months prior to enrollment were randomized to MBSR or psychoeducation/support groups (PES). MBSR focused on mindfulness training; PES focused on CRF self-management. Outcomes included CRF interference (primary), CRF severity and global improvement, vitality, depression, anxiety, sleep disturbance, and pain. Outcomes were assessed at baseline (T1), post-intervention (T2), and 6-month follow-up (T3) using intent-to-treat analysis. Results Between-group differences in CRF interference were not significant at any time point; however, there was a trend favoring MBSR (d=−0.46, p=0.073) at T2. MBSR participants reported significantly greater improvement in vitality (d=0.53, p=0.003) and were more likely to report CRF as moderately-to-completely improved compared to the PES group (χ2 (1)=4.1765, p=0.041) at T2. MBSR participants also reported significantly greater reductions in pain at T2 (d=0.53, p=0.014). In addition, both MBSR and PES produced moderate-to-large and significant within-group improvements in all fatigue outcomes, depression, anxiety, and sleep at T2 and T3 compared to T1. Conclusion MBSR and PES appear efficacious for CRF and related symptoms. Larger trials including a usual care arm are warranted

    Differential expression of VEGF-Axxx isoforms is critical for development of pulmonary fibrosis

    RATIONALE Fibrosis after lung injury is related to poor outcome, and idiopathic pulmonary fibrosis (IPF) can be regarded as an exemplar. Vascular endothelial growth factor (VEGF)-A has been implicated in this context, but there are conflicting reports as to whether it is a contributory or protective factor. Differential splicing of the VEGF-A gene produces multiple functional isoforms including VEGF-Aa and VEGF-Ab, a member of the inhibitory family. To date there is no clear information on the role of VEGF-A in IPF. OBJECTIVES To establish VEGF-A isoform expression and functional effects in IPF. METHODS We used tissue sections, plasma, and lung fibroblasts from patients with IPF and control subjects. In a bleomycin-induced lung fibrosis model we used wild-type MMTV mice and a triple transgenic mouse SPC-rtTATetoCreLoxP-VEGF-Ato conditionally induce VEGF-A isoform deletion specifically in the alveolar type II (ATII) cells of adult mice. MEASUREMENTS AND MAIN RESULTS IPF and normal lung fibroblasts differentially expressed and responded to VEGF-Aa and VEGF-Ab in terms of proliferation and matrix expression. Increased VEGF-Ab was detected in plasma of progressing patients with IPF. In a mouse model of pulmonary fibrosis, ATII-specific deficiency of VEGF-A or constitutive overexpression of VEGF-Ab inhibited the development of pulmonary fibrosis, as did treatment with intraperitoneal delivery of VEGF-Ab to wild-type mice. CONCLUSIONS These results indicate that changes in the bioavailability of VEGF-A sourced from ATII cells, namely the ratio of VEGF-Aa to VEGF-Ab, are critical in development of pulmonary fibrosis and may be a paradigm for the regulation of tissue repair

    The aminopeptidase inhibitor CHR-2863 is an orally bioavailable inhibitor of murine malaria

    Malaria remains a significant risk in many areas of the world, with resistance to the current antimalarial pharmacopeia an everincreasing problem. The M1 alanine aminopeptidase (PfM1AAP) and M17 leucine aminopeptidase (PfM17LAP) are believed to play a role in the terminal stages of digestion of host hemoglobin and thereby generate a pool of free amino acids that are essential for parasite growth and development. Here, we show that an orally bioavailable aminopeptidase inhibitor, CHR-2863, is efficacious against murine malaria
