In this paper, we describe interdependence for assistive technology design, a frame developed to complement the traditional focus on independence in the Assistive Technology field. Interdependence emphasizes collaborative access and people with disabilities' important and often understated contribution in these efforts. We lay the foundation of this frame with literature from the academic discipline of Disability Studies and popular media contributed by contemporary disability justice activists. Then, drawing on cases from our own work, we show how the interdependence frame (1) synthesizes findings from a growing body of research in the Assistive Technology field and (2) helps us orient to additional technology design opportunities. We position interdependence as one possible orientation to, not a prescription for, research and design practice-one that opens new design possibilities and affirms our commitment to equal access for people with disabilities.

Cultural differences in parental feeding practices and children's eating behaviours and their relationships with child BMI: a comparison of Black Afro-Caribbean, White British and White German samples J Blissett and C Bennett BACKGROUND/OBJECTIVES: Childhood obesity rates differ between cultural groups in Europe. Parents influence their children's weight status and eating behaviours through feeding practices. We investigated cultural differences in feeding practices and eating behaviours and their relation to child weight in three groups that differed in cultural background and geographical location. SUBJECTS/METHODS: Fifty-two White German (WG) families, in Germany (44 mothers, mean age 33.8 years), 79 White British (WB) families, in the UK (74 mothers, mean age 37.8) and 40 Black Afro-Caribbean (BAC) families, in the UK (34 mothers, mean age 31.8) participated in this study of 2-12-year-old children. Parents completed questionnaires assessing feeding practices and eating behaviours; children were measured and weighed by experimenters. RESULTS: MANCOVAs indicated that BAC parents used the highest levels of restrictive feeding practices and the lowest levels of monitoring, and their children showed the highest levels of food-approach behaviours. WG parents used the lowest levels of pressure to eat. Partial correlations showed that food-approach behaviours were correlated with child BMI in BAC and WG families but not in WB families. Parental restriction was associated with child Body Mass Index (BMI) in BAC families only. CONCLUSIONS: There are both similarities and differences in feeding practices and eating behaviours and their relationships with child weight in different cultural groups. Findings highlight the importance of being aware of cultural differences when carrying out research with multi-cultural samples in Europe.

The captive population of black rhinoceros (Diceros bicornis) is not self-sustaining. The reasons for suboptimal reproduction and high mortality need to be investigated. This can only be achieved by cross-institutional analyses of environments, behavior, and performance. In this study, we collected data on 23 zoos with black rhinoceros to compare zoo environments with reproductive success, mortality, and behavior. Institutional variation was characterized by enclosure area, percentage of walls around enclosure perimeter, percentage of public access along enclosure perimeter, climate, noise level, number of years zoo has maintained black rhinoceros, frequency of chlorine use, and number of male and female black rhinoceros at a zoo simultaneously. Birth and death rates for each institution were calculated from studbook records. We found that the breeding success of a zoo since 1973 correlated positively with enclosure area, and zoos with two or more females had a lower reproductive rate than zoos with only one female. Females residing during their pre-reproductive years at a zoo with another reproductive female gave birth for the first time on average 3 years later than sole females. Mortality since 1973 correlated positively with percentage of public access. In Part I, we developed behavior profiles of 29.31 individual black rhinoceros from keeper ratings. Scores for males on the behavior trait Fear also correlated positively to percentage of public access, and we suggest that this aspect of black rhinoceros exhibits is a stressor for this species, especially the males. We found that different aspects of captive environments are associated with male and female black rhinoceros behavior. Male scores on the behavior trait dominant were higher in smaller enclosures, and female scores for a group of behaviors suggesting agitation (chasing/stereotypy/mouthing) were positively correlated with percentage of walls in their enclosure. These two behavior traits were found in Part I to be negatively correlated with the breeding success of an individual male or female. We re-surveyed the behavior and husbandry of 29 36 Carlstead et al.black rhinoceros pairs in zoos 2 years after the original data were collected. The re-survey confirmed that compatible black rhinoceros pairs are those with assertive females and submissive males, and that enclosure area and a low percentage of concrete walls around the enclosure are positive predictors of a pair's reproductive success. We conclude that temperament traits of individuals and characteristics of their captive environments both have an impact on a pair's breeding success. Our study demonstrates that cross-institutional comparisons of zoo facilities, when integrated with behavioral assessments of individual animals, are a valuable tool for investigating potential causes of poor reproduction and wellbeing in zoo animals.

2 Key points What is already known about the topic? Treatments for substance use disorders aim at improving health and, most importantly, broader wellbeing. Health-related measures of quality of life may not adequately capture the broader wellbeing benefits associated with such complex interventions. Comprehensive evidence on the validity and responsiveness of these measures in this context is lacking. When broader capability-wellbeing benefits are expected, NICE recommends the parallel use of an ICECAP measure but their measurement properties in this context are yet unknown. What does the paper add to existing knowledge? This is the first study exploring the psychometric properties of the EQ-5D-5L and ICECAP-A measures in the context of drug addiction. The results indicate that the ICECAP-A is a promising measure for capturing both health and broader wellbeing benefits in this context. 3 ABSTRACT Background:Measuring outcomes in economic evaluations of social care interventions is

Low-vision and blind bus riders often rely on known physical landmarks to help locate and verify bus stop locations (e.g., by searching for an expected shelter, bench, or newspaper bin). However, there are currently few, if any, methods to determine this information a priori via computational tools or services. In this article, we introduce and evaluate a new scalable method for collecting bus stop location and landmark descriptions by combining online crowdsourcing and Google Street View (GSV). We conduct and report on three studies: (i) a formative interview study of 18 people with visual impairments to inform the design of our crowdsourcing tool, (ii) a comparative study examining differences between physical bus stop audit data and audits conducted virtually with GSV, and (iii) an online study of 153 crowd workers on Amazon Mechanical Turk to examine the feasibility of crowdsourcing bus stop audits using our custom tool with GSV. Our findings reemphasize the importance of landmarks in nonvisual navigation, demonstrate that GSV is a viable bus stop audit dataset, and show that minimally trained crowd workers can find and identify bus stop landmarks with 82.5% accuracy across 150 bus stop locations (87.3% with simple quality control).
