Expert Yet Vulnerable: Understanding the Needs of Transit Dependent Riders to Inform Policy and Design

Transportation is a crucial resource that links people to jobs, social networks, community and services. The transit dependent -- those who do not own private vehicles -- occupy a unique position. They are expert in their knowledge of public transportation while vulnerable to the failures and limitations of transit. This paper presents the results of a study that is aimed at understanding the lived experience of transit dependent riders. Using a framework of structuration theory as an analytic lens, we provide a thematic analysis of qualitative data including interviews with socially connected groups of people and video diaries. The results demonstrate the expertise that transit dependent riders have about transit and its policies and how they deploy that expertise in productive and cunning ways to make the system work for them. The analysis of this data resulted in three categories of agency to consider when designing for vulnerable populations: resourcefulness, reciprocity and powerlessness. The paper concludes by advocating for a human-centered approach to designing systems in community informatics and offers a set of guiding questions for designers of information and communication technologies (ICTs) to consider, especially with regards to vulnerable populations

Can Resistance Training Contribute to the Aerobic Components of the Physical Activity Guidelines?

International Journal of Exercise Science 7(4) : 278-285, 2014. To evaluate if resistance training can reach Moderate to Vigorous Intensity (MVI) and contribute to the aerobic component of the international physical activity guidelines. Sixteen participants aged between 20 and 35 were recruited. Heart rate was recorded by heart rate monitor during a resistance training program. Based on maximal heart rate, time spent at MVI (55-69% of maximal heart rate) was calculated. Participants displayed a HR equal or above MVI for 51.5% ± 21.7% of time. When stratifying by lower and upper body sessions, that proportion was median (25-75th); 75.0% (32.5%-89.2%) and 45.8% (30.0%-66.8%) respectively. Body mass (r=.68; p\u3c.01), body mass index (r=.54; p=.03), and leg press strength (r=.59; p=02) were positively associated with time spent at MVI. Assuming 10-minute bouts of aerobic exercise are not needed to achieve health benefits, it is possible to reach MVI with resistance training. Emphasis on the importance of performing resistance training should be done to reach the aerobic component of the physical activity guidelines and optimize health benefits. This provides an alternative option to those who may have difficulty or be unable to reach the required aerobic intensity by traditional aerobic exercises
