Smartphone Apps in Education: Students Create Videos to Teach Smartphone Use as Tool for Learning

Smartphones are regular classroom accessories. Educators should work with children to understand the capacity of smartphones for learning and civic engagement, rather than being a classroom distraction. This research supports a collaborative project the authors engaged in with students in two states to discover what the perception of smartphone use was by students and teachers. One element of this project included students producing YouTube style tutorials on the educational use of mobile apps. The authors explored smartphone use in the classroom. Student created products correlated to technology trends in K-12 education and their relationship with state by state demographic data

Family transfers and long-term care: An analysis of the WHO Study on global AGEing and adult health (SAGE).

BACKGROUND: Populations globally are ageing, resulting in increased need for long-term care. Where social welfare systems are insufficient, these costs may fall to other family members. We set out to estimate the association between long-term care needs and family transfers in selected low- and middle- income countries. METHODS: We used data from the World Health Organization's Study on global AGEing and adult health (SAGE). Using regression, we analysed the relationship between long-term care needs in older households and i) odds of receiving net positive transfers from family outside the household and ii) the amount of transfer received, controlling for relevant socio-demographic characteristics. RESULTS: The proportion of household members requiring long-term care was significantly associated with receiving net positive transfers in China (OR: 1.76; p = 0.023), Ghana (OR: 2.79; p = 0.073), Russia (OR: 3.50; p < 0.001). There was a statistically significant association with amount of transfer received only in Mexico (B: 541.62; p = 0.010). CONCLUSION: In selected LMICs, receiving family transfers is common among older households, and associated with requiring long-term care. Further research is needed to better understand drivers of observed associations and identify ways in which financial protection of older adults' long-term care needs can be improved

Comparison of Tabu/2‐opt heuristic and optimal tree search method for assignment problems

A nonlinear cooperative control problem involving several vehicles is detailed and solved. The vehicles must be assigned to perform many tasks such that they obey constraints on the order of task completion and minimize a nonlinear objective function, the total time to finish all tasks. This is an example of a combinatorial task assignment problem. A novel heuristic is introduced that represents a new combination of two combinatorial optimization tools. The quality of the solutions produced by this heuristic is demonstrated through comparison with a branch and bound search method. The branch and bound method is a well‐known procedure and finds optimal solutions to the constrained, nonlinear task assignment problem.

Leveraging a Community-Based Research Approach to Explore Research Perceptions Among Suburban Poor and Underserved Populations

This qualitative study explored perceptions of research among a rapidly growing underserved population within a suburban community, a setting that has yet to be sufficiently explored using a community-based research (CBR) approach. We recruited community members from community health care agencies in DuPage County, Illinois, and 79 participants were enrolled in the study. Community researchers conducted nine focus groups comprised of agency clients and eight stakeholder interviews to collect community perspectives regarding the meaning of research and its community impact, current and desired channels of research information, and research motives, discrimination, and funding. Findings revealed four major themes: community members 1) often associate research with medical research or community engagement; 2) rely most heavily on the internet for research information; 3) perceive financial barriers, rather than racial or ethnic barriers, as a significant obstacle to receiving the benefits of research; and 4) trust research conducted by academic institutions

Controlled nucleation of hydroxyapatite on alginate scaffolds for stem cell-based bone tissue engineering

Current bone tissue engineering strategies aim to grow a tissue similar to native bone by combining cells and biologically active molecules with a scaffold material. In this study, a macroporous scaffold made from the seaweed-derived polymer alginate was synthesized and mineralized for cell-based bone tissue engineering applications. Nucleation of a bone-like hydroxyapatite mineral was achieved by incubating the scaffold in modified simulated body fluids (mSBF) for 4 weeks. Analysis using scanning electron microscopy and energy dispersive x-ray analysis indicated growth of a continuous layer of mineral primarily composed of calcium and phosphorous. X-ray diffraction analysis showed peaks associated with hydroxyapatite, the major inorganic constituent of human bone tissue. In addition to the mineral characterization, the ability to control nucleation on the surface, into the bulk of the material, or on the inner pore surfaces of scaffolds was demonstrated. Finally, human MSCs attached and proliferated on the mineralized scaffolds and cell attachment improved when seeding cells on mineral coated alginate scaffolds. This novel alginate- HAP composite material could be used in bone tissue engineering as a scaffold material to deliver cells, and perhaps also biologically active molecules. © 2010 Wiley Periodicals, Inc.

Coping with healthcare costs for chronic illness in low-income and middle-income countries : A systematic literature review

Background Experiencing illness in low-income and middle-income countries (LMICs) can incur very high out-of-pocket (OOP) payments for healthcare and, while the existing literature typically focuses on levels of expenditure, it rarely examines what happens when households do not have the necessary money. Some will adopt one or more â € coping strategies', such as borrowing money, perhaps at exorbitant interest rates, or selling assets, some necessary for their future income, with detrimental long-term effects. This is particularly relevant for chronic illnesses that require consistent, long-term OOP payments. We systematically review the literature on strategies for financing OOP costs of chronic illnesses in LMICs, their correlates and their impacts on households. Methods We searched MEDLINE, EconLit, EMBASE, Global Health and Scopus on 22 October 2018 for literature published on or after 1 January 2000. We included qualitative or quantitative studies describing at least one coping strategy for chronic illness OOP payments in a LMIC context. Our narrative review follows Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines. Results Forty-seven papers were included. Studies identified coping strategies for chronic illness costs that are not traditionally addressed in financial risk protection research (eg, taking children out of school, sending them to work, reducing expenditure on food or education, quitting work to give care). Twenty studies reported socioeconomic or other correlates of coping strategies, with poorer households and those with more advanced disease more vulnerable to detrimental strategies. Only six studies (three cross-sectional and three qualitative) included evidence of impacts of coping strategies on households, including increased labour to repay debts and discontinuing treatment. Conclusions Monitoring of financial risk protection provides an incomplete picture if it fails to capture the effect of coping strategies. This will require qualitative and longitudinal research to understand the long-term effects, especially those associated with chronic illness in LMICs
