Assisted Living Systems: Human Factors Considerations

Although many older adults wish to live independently, remaining in their own homes as long as possible, they may face obstacles such as transportation issues, social isolation, upkeep of the home, and increasing in-home care costs, which prevent them from doing so. The use of technology within the home, through technology-based assisted living systems, has the potential to alleviate some of these obstacles. Incorporating human factors principles to maximize safety, efficiency, and usability is key to the development of these systems

Persistence Among African-American Males in the Honors College

Retaining African American students, specifically African American males, is an issue that plagues the American higher education system. Research shows that African American male students are the lowest represented group in the gifted studies programs (Ford, 2010). Lockie and Burke (1999); Chen and DeJardins (2010) and Bell (2010a) found that barriers to African American male retention in higher education include but are not limited to the following: financial assistance, the battle of the two-self concept, lack of mentoring/advising, low expectations from faculty, and alienation. In an effort to remove these barriers, institutions have implemented retention strategies such as more faculty mentoring and retention programs. The purpose of this qualitative study was to investigate the reported experiences of African American males enrolled in the Honors College; specifically, gathering information regarding academic and non-academic factors that impact their motivation to persist. Employing empirical phenomenology, the researcher interviewed 12 African American males from Predominantly White Institutions (PWI) in the southeastern region. The researcher ultimately determined that participation in the Honors College did not affect the males’ motivation to persist in college and only affected a few males who were persisting in the Honors College

Costs and quality of life associated with osteoporosis related fractures - Results from a Swedish survey

There are few studies investigating the consequences of osteoporotic (low bone density) fractures in terms of costs and health outcomes. The purpose of this Swedish pilot study is to assess the costs and quality of life related to fractures of the hip, spine, wrist and shoulder and further to identify important cost items that should be included in future studies in this area. Data were collected using a questionnaire administered by a nurse at Malmö University Hospital. The costs are collected based on a societal perspective and include both direct and indirect costs. Health effects were measured by the EuroQol questionnaire, rating scale method and the SF-36. The total costs varied between SEK 23 000 for a wrist fracture and SEK 63 000 for a hip fracture. Although that the response rate is low the cost and quality of life related to hip fracture are close to the results presented in other studies. The major new finding is that spine fractures are associated with higher costs and lower quality of life than previously assumed. Future studies must include a sufficient number of patients in order to obtain reliable cost and health effect estimates after osteoporotic fractures in general and after spine fractures in particular. Such studies will provide important inputs for health economic evaluations assessing the cost-effectiveness of the treatment and prevention of osteoporosis.costs; fracture; osteoporosis; quality of life

Efficient Optimization of Dominant Set Clustering with Frank-Wolfe Algorithms

We study Frank-Wolfe algorithms - standard, pairwise, and away-steps - for efficient optimization of Dominant Set Clustering. We present a unified and computationally efficient framework to employ the different variants of Frank-Wolfe methods, and we investigate its effectiveness via several experimental studies. In addition, we provide explicit convergence rates for the algorithms in terms of the so-called Frank-Wolfe gap. The theoretical analysis has been specialized to Dominant Set Clustering and covers consistently the different variants

How chronic is polypharmacy in old age? A longitudinal nationwide cohort study

OBJECTIVE: To evaluate the chronicity of polypharmacy among older adults, and to identify factors associated with chronic polypharmacy. DESIGN: Longitudinal cohort study using register data. SETTING: Nationwide, Sweden. PARTICIPANTS: All 711,432 older adults (≥65 years) living in Sweden with 5 or more prescription drugs in October 2010 were included and followed-up until December 2013. Mean age at baseline was 77 (SD, 7.8) years, 59% were women, and 7% lived in nursing homes. MEASUREMENT: Monthly changes in the exposure to polypharmacy. Data regarding prescription drug use were extracted from the Swedish Prescribed Drugs Register. RESULTS: Overall, 82% were continuously exposed to polypharmacy during ≥6 months, and 74% during ≥12 months. The proportion of individuals who remained exposed until the end of the study was 55%. Among the 21,361 individuals who had not been exposed to polypharmacy during the 6-month period before baseline (i.e. with a new episode of polypharmacy), only 30% remained exposed for ≥6 months. The proportion of older adults who spent at least 80% of their follow-up time with polypharmacy was substantially higher among prevalent polypharmacy users at baseline than among those with a new polypharmacy episode (80% vs 24%, p<0.01). Factors associated with chronic polypharmacy included higher age, female gender, living in an institution, chronic multimorbidity, and multi-dose dispensing. CONCLUSION: Polypharmacy is most often chronic, although a substantial share of older adults experience short, recurring episodes of polypharmacy and are thus exposed to its potential harms in a transient rather than persistent manner.Swedish Research Council (2015-03618)Accepte

Party Platforms as Sources of Public Policy in Texas, 1946-1963

"This study is being made to assess the actual importance of the platform in recent gubernatorial elections in Texas. Because an intensive analysis is undertaken, the scope of this thesis has been limited in two ways. First, it is confined to the years 1946-1963 spanning the Administrations of Governors Beauford Jester, Allan Shivers, and Price Daniel. Secondly, in an attempt to compare the executives with one another, platform promises related to education, health and welfare, highways, and taxation adopted at the Democratic State Convention have been included. The method utilized to determine fulfillment of a political promise has been to compare the Governor's recommendations to the Legislature with the resulting action. In particular, an attempt has been made to (1) describe the Democratic primary election, with special reference to the issues raised; (2) to discuss the Democratic State Convention with a listing of the planks mentioned above; and (3) to analyze proposals in the Governor's State of the State Messages and special messages and to compare them with the resulting legislative action." -- leaf 1
