- Abstract
Background: Active workstation alternatives (e.g., treadmill desks and pedal desks) have the potential to elevate workplace energy expenditure by replacing occupational sedentary behavior with opportunities to generate low-intensity non-exercise physical activity, but only to the extent that workers find them acceptable and congruent with their primary working tasks and therefore can frequently use them for extended periods of time., Objective: To assess workers' acceptability of the Pennington Pedal Desk™., Methods: Full-time sedentary workers (N = 42; 76% female; mean+SD age 39.6±11.3 years; BMI 25.7±5.4 kg/m2) used the pedal desk for 15 minutes while they: 1) searched the internet, 2) composed an email, and 3) completed acceptability ratings using an online Likert scale anchored from 1/strongly disagree to 5/strongly agree. Garmin Vector power meter pedals and EDGE 510 GPS bike computer (Garmin ®, USA) continuously captured revolutions per minute (RPM) and power., Results: Participants indicated that they would use the pedal desk for 4 (median) hours per work day and 97.6% of participants were somewhat or completely confident that they could type proficiently while using the pedal desk. Participants pedaled at 54.8±11.2 RPM and 23.1±8.6 watts (mean+SD)., Conclusions: Participants rated the Pennington Pedal Desk™ workstation positively and indicated potential for extended daily use.

- Abstract
Objective: Mindfulness is theorized to affect the eating behavior and weight of pregnant women, yet no measure has been validated during pregnancy., Methods: This study qualitatively and quantitatively evaluated the reliability and validity of the Mindful Eating Questionnaire (MEQ) in overweight and obese pregnant women. Participants completed focus groups and cognitive interviews. The MEQ was administered twice to measure test-retest reliability. The Eating Inventory (EI) and Mindful Attention Awareness Scale (MAAS) were administered to assess convergent validity, and the Neighborhood Environment Walkability Scale (NEWS) assessed discriminant validity., Results: Participants were 20 ± 8 weeks gestation (mean ± SD), 30 ± 2 years old, and 55% were obese. The MEQ total score had good test-retest reliability (r = .85). The total score internal consistency reliability was poor (Cronbach's α = .56). The external cues subscale (ECS) was not internally consistent (α = .31). Other subscales ranged from α = .59-.68. When the ECS was excluded, the MEQ total score internal consistency was acceptable (α = .62). Convergent validity was supported by the MEQ total score (with and without ECS) correlating significantly with the MAAS and the EI disinhibition and hunger subscales. Discriminant validity of the MEQ was supported by the MEQ and NEWS total scores and subscales not being significantly correlated. The quantitative results were supported by the qualitative context and content analysis., Conclusion: With the exception of the ECS, the MEQ's reliability and validity was supported in pregnant women, and most of the subscales were more robust in pregnant women than in the original sample of healthy adults. The MEQ's use with overweight and obese pregnant women is supported., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

- Abstract
Background: This study tested the validity of revolutions per minute (RPM) measurements from the Pennington Pedal Desk™. Forty-four participants (73 % female; 39 ± 11.4 years-old; BMI 25.8 ± 5.5 kg/m(2) [mean ± SD]) completed a standardized trial consisting of guided computer tasks while using a pedal desk for approximately 20 min. Measures of RPM were concurrently collected by the pedal desk and the Garmin Vector power meter. After establishing the validity of RPM measurements with the Garmin Vector, we performed equivalence tests, quantified mean absolute percent error (MAPE), and constructed Bland-Altman plots to assess agreement between RPM measures from the pedal desk and the Garmin Vector (criterion) at the minute-by-minute and trial level (i.e., over the approximate 20 min trial period)., Results: The average (mean ± SD) duration of the pedal desk trial was 20.5 ± 2.5 min. Measures of RPM (mean ± SE) at the minute-by-minute (Garmin Vector: 54.8 ± 0.4 RPM; pedal desk: 55.8 ± 0.4 RPM) and trial level (Garmin Vector: 55.0 ± 1.7 RPM; pedal desk: 56.0 ± 1.7 RPM) were deemed equivalent. MAPE values for RPM measured by the pedal desk were small (minute-by-minute: 2.1 ± 0.1 %; trial: 1.8 ± 0.1 %) and no systematic relationships in error variance were evident by Bland-Altman plots., Conclusion: The Pennington Pedal Desk™ provides a valid count of RPM, providing an accurate metric to promote usage.

- Abstract
Using interviews with 43 college-age individuals, the present study aims to create a more nuanced and complex understanding of the relationship between alcohol and gender in instances of sexual victimization. The existing scholarship suggests that either alcohol or gendered processes are the primary factors in facilitating a sexual assault, one always dominating the other. However, participants express a more complex understanding that suggests that not only do each of these factors contribute individually to sexual victimization, but they also interact to create a context in which sexual victimization is not only possible but also likely. In these in-depth interviews, participants reveal the ways in which the physiological effects of alcohol, beliefs about alcohol, gender norms, sex scripts, and rape myths all work together to normalize male dominance and violence against women. Given that sexual assaults among college-age women have not declined in the past 50 years and alcohol consumption is present in upward of 50% of all assaults, it is critical that scholars continue to disentangle this relationship and reformulate the way we conceptualize sexual violence.

- Abstract
Background: The aim was to develop a tool that measures patient dependency and disease severity in children with mild to severe liver disease., Methods: The initial pilot score was based on known markers of disease severity in acute and chronic liver disease. Between 1997 and 2001, the score was modified 4 times and reduced to comprise 10 key parameters: aspartate transaminase, prothrombin time, albumin, bilirubin, ascites, nutritional support, organ dysfunction, blood product support, sepsis and intravenous access. The score's face validity, internal consistency, interobserver agreement and construct validity were evaluated statistically and by the use of endpoints such as survival and transplant after 6 months., Results: The final 10 variable score was tested on 71 children admitted over two 3-month periods. The Cronbach's alpha score (a test for internal consistency) for the total score was 0.72. Serial data paralleled clinical deterioration and response to interventions. A Paediatric Hepatology Dependency score >15 had an odds ratio of 7 (P = 0.0125) for death or transplant at 6 months. The score was also found to agree with the paediatric end-stage liver disease score for the 12 patients being listed for liver transplantation (r = 0.660, P < 0.05)., Conclusion: The Paediatric Hepatology Dependency score is valid and internally consistent and is a convenient measure of dependency and disease severity in a heterogeneous group of patients with liver disease. It also allows admissions to be audited for comparison between eras and for monitoring the progress of patients while on the ward.
