Chronic Health Conditions as a Risk Factor for Falls among the Community-Dwelling US Older Adults: A Zero-Inflated Regression Modeling Approach

Falls are an important health concern among older adults due to age-related changes in the body. Having a medical history of chronic health condition may pose even higher risk of falling. Only few studies have assessed a number of chronic health conditions as risk factor for falls over a large nationally representative sample of US older adults. In this study, Behavioral Risk Factor Surveillance System (BRFSS) 2014 participants aged 65 years and older (n = 159,336) were evaluated. It was found that 29.7% (n = 44,550) of the sample experienced at least one fall and 16.3% (n = 20,444) experienced more than one fall in the past 12 months. According to the study findings, having a medical history of stroke, CKD, arthritis, depression, and diabetes independently predict the risk of first-time falling as well as the risk of recurrent falling in older adult population while controlling for other factors. On the other hand, having a medical history of the heart attack, angina, asthma, and COPD did not predict the risk of first-time falling, but did predict the risk of recurrent falling after experiencing the first fall in this population

A chilly conference climate: The influence of sexist conference climate perceptions on women's academic career intentions

Despite women's increased presence in academia, women are still underrepresented in faculty positions relative to men. Though many obstacles interfere with women's academic career success, including family responsibilities and disproportionate resources relative to men (Ceci & Williams, 201l; Lewis, 2009), this research focused on the conference context as one potential contributor to women's academic career intentions. The present research explored the extent to which sexist climate perceptions were related to women's experiences during the conferences, their coping tactics, and their academic exit intentions relative to men's. The conference context was chosen because conferences have yet to be empirically examined for their potential to influence women's consideration of an academic career (Jacobs & McFarlane, 2005). Presenters (63% women) from three national academic conferences completed an online survey. Results showed that the greater representation of women at the conference, the less sexist attendees perceived the conference. Additionally, women who perceived the conference as sexist and silenced during the conference expressed increased intention to exit from academic careers. On the other hand, men who perceived the conference as sexist expressed increased intention to exit from that particular conference, rather than academia. Implications for conference attendees, conferences, and academia are discussed

Rocket exhaust plume computer program improvement. Volume 1: Summary: Method of characteristics nozzle and plume programs

A summary is presented of the various documents that discuss and describe the computer programs and analysis techniques which are available for rocket nozzle and exhaust plume calculations. The basic method of characteristics program is discussed, along with such auxiliary programs as the plume impingement program, the plot program and the thermochemical properties program

Analysis of heating rates and forces on bodies subject to rocket exhaust plume impingement

Computer programs and engineering methods for calculating heating rates and forces in jet plume impingement problem

Key Components of Tourism Revenue in Appalachian Kentucky

This paper examines variables that contribute to tourism revenues as reported by the state of Kentucky for a sample of 54 counties in Appalachian Kentucky. The study utilized five components of tourism, online promotional information, and reported tourism revenues to identify what variables contribute to regional tourism revenues. Regression analysis using factor scores found two factors influenced employment and one factor influenced direct tourism revenue

Online Learning in Schools of Business: The Impact of Strategy on Course Enrollments

Online education in schools of business is an ongoing, emerging practice. Strategic planning by institutions and programs seeks to identify the most relevant factors in providing the most effective online learning for students. This requires that schools of business figure out what factors positively and directly affect course enrollments. This research study surveyed deans of AACSB-accredited business schools to determine their online learning strategies and practices. The results of the survey and study support online education as a means to meet the increasing needs of a diverse and ever-changing student population both now and in the future

Intrinsic and extrinsic motivational factors and Type A behavior pattern

In this study motivational factors were examined to determine if subjects were more intrinsically or extrinsically motivated. In addition, Type A behavior pattern was assessed to determine if a link exists between motivation and Type A behavior. A total of 176 students from a small midwestern university participated in this research. Intrinsic motivation was manipulated by using one of two movies, one interesting and one boring. Extrinsic motivation was measured by manipulating the number of extra credit points given for participation. Participants were assigned to one of four conditions: High intrinsic/low extrinsic, high intrinsic/high extrinsic, low intrinsic/low extrinsic, and low intrinsic/high extrinsic. Type A and Type B behavior were assessed using the results of the student version of Jenkins Activity Scale (JAS). Neither intrinsic nor extrinsic motivation were found to influence participants behavior. However, Type A individuals were more motivated to show-up for the movie than Type B individuals

Penning traps with unitary architecture for storage of highly charged ions

Penning traps are made extremely compact by embedding rare-earth permanent magnets in the electrode structure. Axially-oriented NdFeB magnets are used in unitary architectures that couple the electric and magnetic components into an integrated structure. We have constructed a two- magnet Penning trap with radial access to enable the use of laser or atomic beams, as well as the collection of light. An experimental apparatus equipped with ion optics is installed at the NIST electron beam ion trap (EBIT) facility, constrained to fit within 1 meter at the end of a horizontal beamline for transporting highly charged ions. Highly charged ions of neon and argon, extracted with initial energies up to 4000 eV per unit charge, are captured and stored to study the confinement properties of a one-magnet trap and a two-magnet trap. Design considerations and some test results are discussed
