The Rise of Computing Research in East Africa: The Relationship Between Funding,Capacity and Research Community in a Nascent Field

The emergence of vibrant research communities of computer scientists in Kenya and Uganda has occurred in the context of neoliberal privatization, commercialization, and transnational capital flows from donors and corporations. We explore how this funding environment configures research culture and research practices, which are conceptualized as two main components of a research community. Data come from a three-year longitudinal study utilizing interview, ethnographic and survey data collected in Nairobi and Kampala. We document how administrators shape research culture by building academic programs and training growing numbers of PhDs, and analyze how this is linked to complicated interactions between political economy, the epistemic nature of computer science and sociocultural factors like entrepreneurial leadership of key actors and distinctive cultures of innovation. In a donor-driven funding environment, research practice involves scientists constructing their own localized research priorities by adopting distinctive professional identities and creatively structuring projects. The neoliberal political economic context thus clearly influenced research communities, but did not debilitate computing research capacity nor leave researchers without any agency to carry out research programs. The cases illustrate how sites of knowledge production in Africa can gain some measure of research autonomy, some degree of global competency in a central arena of scientific and technological activity, and some expression of their regional cultural priorities and aspirations. Furthermore, the cases suggest that social analysts must balance structure with culture, place and agency in their approaches to understanding how funding and political economy shape scientific knowledge.     

Ethnicity as a moderator of the theory of planned behavior and physical activity in college students

Most college students do not meet physical activity (PA) guidelines, and ethnic disparities exist. The present study examined the utility of the theory of planned behavior (TPB) in explaining PA intentions and behavior in black and white college students and whether any TPB relationships were moderated by ethnicity. Black (n=170) and white (n=180) students completed a baseline TPB questionnaire and PA assessment 2 weeks later Hierarchical latent variable regression analyses showed that affective attitude, subjective norm, and perceived behavioral control (PBC) were significant predictors of intention for both ethnic groups, whereas the PBC-intention relationship was significantly stronger for white students. Intention significantly predicted PA for both ethnic groups. Furthermore, common and ethnic-specific beliefs were identified.     

Social and Environmental Factors Associated With Preschoolers' Nonsedentary Physical Activity

The twofold purposes of the investigation were (a) to describe with direct observation data the physical activity behaviors and the accompanying social and environmental events of those behaviors for children in preschools and (b) to determine which contextual conditions were predictors of moderate to vigorous physical activity (MVPA) and nonsedentary physical activity (i.e., light activity + MVPA) for 3-, 4-, and 5-year-old children during their outdoor play. The results indicate that preschoolers' physical activity is characterized as sedentary in nature throughout their preschool day (i.e., 89% sedentary, 8% light activity, and 3% MVPA). During outdoor play periods, when children are most likely to be physically active, some contextual and social circumstances better predict their physical activity. Implications for policy makers, practitioners, and researchers are discussed.     

Reduced barriers mediated physical activity maintenance among breast cancer survivors

To better understand mechanisms of physical activity (PA) behavior change in breast cancer survivors, we examined mediation of a successful PA behavior change intervention by social cognitive theory (SCT) constructs. Our exploratory study randomized 41 breast cancer survivors to receive the 3-month intervention (INT) or usual care (UC). We used the Freedman and Schatzkin approach to examine mediation of intervention effect on PA 3 months postintervention by changes in SCT constructs from baseline to immediately postintervention. Compared with UC, the INT group reported lower barriers interference (mean difference = -7.8, 95% CI [-15.1, -0.4], d = -0.67, p = .04) and greater PA enjoyment (mean difference = 0.7, 95% CI [0, 1.5], d = 0.61, p = .06). Barriers interference mediated 39% (p = .004) of the intervention effect on PA 3 months postintervention. PA enjoyment was not a significant mediator. Reducing barriers to PA partially explained our intervention effect.     

What to Do With Meaning? A Research Conundrum for the 21st Century

It is difficult to know what to do with meaning. Some kinesiologists, particularly those in the humanities, would argue that it should be given due attention—perhaps even priority attention. Others would argue that meaning is unimportant or simply impossible to study in any objective way. This conundrum can be solved by adopting a new research paradigm, one that places meaning on a level playing field with muscles, cells, genes, and other movement-related phenomena. I argue that we might be in the middle of a Kuhnian paradigm shift. This new way of conceptualizing reality has significant implications, not only for how we do research, but also for how we understand our field. I identify five implications of the new paradigm for kinesiology.
