Development of an aerobic capacity prediction model from one-mile run/walk performance in adolescents aged 13–16 years

A popular algorithm to predict VO_2Peak from the one-mile run/walk test (1MRW) includes body mass index (BMI), which manifests practical issues in school settings. The purpose of this study was to develop an aerobic capacity model from 1MRW in adolescents independent of BMI. Cardiorespiratory endurance data were collected on 90 adolescents aged 13–16 years. The 1MRW was administered on an outside track and a laboratory VO_2Peak test was conducted using a maximal treadmill protocol. Multiple linear regression was employed to develop the prediction model. Results yielded the following algorithm: VO_2Peak = 7.34 × (1MRW speed in m s^?1) + 0.23 × (age × sex) + 17.75. The New Model displayed a multiple correlation and prediction error of R = 0.81, standard error of the estimate = 4.78 ml kg^?1·min^?1, with measured VO_2Peak and good criterion-referenced (CR) agreement into FITNESSGRAM’s Healthy Fitness Zone (Kappa = 0.62; percentage agreement = 84.4%; Φ = 0.62). The New Model was validated using k-fold cross-validation and showed homoscedastic residuals across the range of predicted scores. The omission of BMI did not compromise accuracy of the model. In conclusion, the New Model displayed good predictive accuracy and good CR agreement with measured VO_2Peak in adolescents aged 13–16 years.     

Occupational branding for diversity: managing discursive contradictions

In line with recent efforts to increase the representation of women in the field of computing and information technology (I.T.), the National Center for Women and Information Technology has spearheaded an occupational branding campaign that seeks to encourage more women to enter this field. We use this campaign as a case study to investigate how representations of work in an occupational branding campaign (“official branding discourse”) compare with the ways in which practitioners represent this work (“unofficial branding discourse”). Through our analysis, we show that whereas the official branding discourse represents computing and I.T. as a field where women are valued, unofficial branding discourse represents this field as hostile to women. We then propose three avenues through which these contradictions can be managed: (1) acknowledging the challenges expressed by practitioners, while simultaneously discussing how to foster a more inclusive occupational culture, (2) changing the primary goal of the campaign from increasing the number of women in computing and I.T. to making the culture of computing and I.T. less hostile, and (3) committing fewer resources into organized branding campaigns and more resources into direct organizational interventions that seek to make work environments inclusive.     

Educating for Ecological Conversion: An Ecstatic Pedagogy for Christian Higher Education amid Climate Crisis

Abstract

Christian universities are obligated by their mission to confront the climate crisis as the pressing existential issue of our time. In his encyclical Laudato Si', Pope Francis calls for the ecological conversion of the church and all of humanity. Ecological conversion entails an existential shift from a relationship with the earth marked by possessive, wasteful consumption to one marked by delight in creation, concern for its suffering, and preservation of this divine gift. Following the work of Bernard Lonergan and Robert Doran on conversion, we propose pedagogical strategies of connectedness and encounter that emphasize the psychic dimension of ecological conversion.
