The Association between Cultural Views of Cancer and Colorectal Cancer Screening Behavior among Asian Americans in the Washington, D.C. Metropolitan Area

Objective: To evaluate the association between Asian cultural views of cancer and colorectal cancer screening behavior among Asian Americans in the Washington, D.C. metropolitan area. Methods: A cross-sectional examination was conducted of 858 Chinese, Korean, and Vietnamese adults. Logistic regression was used to investigate the relationship between Asian cultural views (using 16-items from a previously developed scale) and colorectal cancer screening (self-reported yes/no). Results: When examining 10-point increases in continuous cultural views scores, a 12% (OR=0.88; 95% CI:0.82-0.97) and 7% (OR=0.93; 95% CI:0.87-1.00) decreased likelihood that an individual received screening were observed for herb use and self-care scores respectively. When examining categorical cultural views scores (Asian, Neutral, and Western), herb use and self-care were significantly associated with screening and showed a gradient effect after adjusting for age. Conclusion: Findings suggest that culturally appropriate interventions that address specific cultural views of cancer can potentially increase colorectal cancer screening among Asian Americans

Concurrent Management of Exercise and Other Valued Life Goals: A Focus on Self-Regulatory Efficacy

While being physically active is an important and valued goal for many individuals, family, work, school, and friends are also valued aspects of their lives. Many social cognitive theories examine health behaviours in isolation, without taking into consideration the context, or life circumstances, in which people seek to achieve such health behaviours. Examining a single goal-directed behaviour without acknowledging the possible influence of other concurrent goals managed by an individual may oversimplify the self-regulation needed in daily life. The overarching purpose of this dissertation was to examine exercise behaviour in the context of concurrently held, valued non-exercise activities (e.g., academics, family). Relationships between valued non-exercise goals, concurrent self-regulatory efficacy, and physical activity behaviour were explored. Social cognitive theory provided the theoretical framework for the three studies conducted. Study 1 sought to discriminate university students whose physical activity level was either commensurate or not with achieving health benefits using social-cognitive predictors. These predictors took into account participants’ beliefs about the concurrent management of physical activity with other valued non-exercise goals. Results indicated that concurrent self-regulatory efficacy (belief in abilities to self-regulate the management of multiple goals including exercise) discriminated those active enough to achieve health benefits from those who were not active enough. Study 2 used a prospective design to explore potential mechanisms that allow individuals to successfully self-regulate exercise behaviour with other goals during hectic times. Undergraduate students were observed during a 4-week examination period where they faced greater than usual challenges to exercising regularly. Concurrent self-regulatory efficacy was identified as a partial mediator of the relationship between value of an exercise goal and future exercise behaviour, and this effect was stable during this challenging period of time. Study 3 used a randomized experimental design to test the social cognitive theory hypothesis that individuals with greater concurrent self-regulatory efficacy would persevere with exercise to a greater extent when facing numerous exercise barriers than their lower efficacy counterparts. Forty-nine busy working mothers with young children who were exercisers or wanted to exercise comprised the study sample. Participants either high or low in concurrent self-regulatory efficacy were exposed to numerous or minimal exercise barrier scenarios. Consistent with social cognitive theory, when exercise barriers were numerous, mothers with higher concurrent self-regulatory efficacy demonstrated greater perseverance towards achieving their exercise goals, and perceived the concurrent management of exercise along with their other valued life goals as more positively challenging, than did mothers with lower concurrent self-regulatory efficacy. Taken together, these results provide preliminary support for the utility of using social cognitive theory to examine beliefs about concurrent self-regulation of exercise along with other valued non-exercise goals when studying exercise behaviour. Future directions and applications to theory are discussed

Optimization of Window Positions for Wind-Driven Natural Ventilation Performance

This paper optimizes opening positions on building facades to maximize the natural ventilation’s potential for ventilation and cooling purposes. The paper demonstrates how to apply computational fluid dynamics (CFD) simulation results to architectural design processes, and how the CFD-driven decisions impact ventilation and cooling: (1) background: A CFD helps predict the natural ventilation’s potential, the integration of CFD results into design decision-making has not been actively practiced; (2) methods: Pressure data on building facades were obtained from CFD simulations and mapped into the 3D modeling environment, which were then used to identify optimal positions of two openings of a zone. The effect of the selected opening positions was validated with building energy simulations; (3) results: The cross-comparison study of different window positions based on different geographical locations quantified the impact on natural ventilation effectiveness; and (4) conclusions: The optimized window positions were shown to be effective, and some optimal solutions contradicted the typical cross-ventilation strategy

Acceptance of Swedish e-health services

Mary-Louise Jung1, Karla Loria11Division of Industrial Marketing, e-Commerce and Logistics, Lulea University of Technology, SwedenObjective: To investigate older people’s acceptance of e-health services, in order to identify determinants of, and barriers to, their intention to use e-health.Method: Based on one of the best-established models of technology acceptance, Technology Acceptance Model (TAM), in-depth exploratory interviews with twelve individuals over 45 years of age and of varying backgrounds are conducted.Results: This investigation could find support for the importance of usefulness and perceived ease of use of the e-health service offered as the main determinants of people’s intention to use the service. Additional factors critical to the acceptance of e-health are identified, such as the importance of the compatibility of the services with citizens’ needs and trust in the service provider. Most interviewees expressed positive attitudes towards using e-health and find these services useful, convenient, and easy to use.Conclusion: E-health services are perceived as a good complement to traditional health care service delivery, even among older people. These people, however, need to become aware of the e-health alternatives that are offered to them and the benefits they provide.Keywords: health services, elderly, technology, Internet, TAM, patient acceptance, health-seeking behavio

Severe B Cell Deficiency in Mice Lacking the Tec Kinase Family Members Tec and Btk

The cytoplasmic protein tyrosine kinase Tec has been proposed to have important functions in hematopoiesis and lymphocyte signal transduction. Here we show that Tec-deficient mice developed normally and had no major phenotypic alterations of the immune system. To reveal potential compensatory roles of other Tec kinases such as Bruton's tyrosine kinase (Btk), Tec/Btk double-deficient mice were generated. These mice exhibited a block at the B220+CD43+ stage of B cell development and displayed a severe reduction of peripheral B cell numbers, particularly immunoglobulin (Ig)MloIgDhi B cells. Although Tec/Btknull mice were able to form germinal centers, the response to T cell–dependent antigens was impaired. Thus, Tec and Btk together have an important role both during B cell development and in the generation and/or function of the peripheral B cell pool. The ability of Tec to compensate for Btk may also explain phenotypic differences in X-linked immunodeficiency (xid) mice compared with human X-linked agammaglobulinemia (XLA) patients
