The prevalence of urinary incontinence (UI) among older urban Latinos is high. Insight into etiologies of and contributing factors to the development of this condition is needed. This longitudinal cohort study identified correlates of 1-year incidence of UI in older community-dwelling Latino adults participating in a senior center-based physical activity trial in Los Angeles, California. Three hundred twenty-eight Latinos aged 60 to 93 participating in Caminemos, a randomized trial to increase walking, were studied. Participants completed an in-person survey and physical performance measures at baseline and 1 year. UI was measured using the International Consultation on Incontinence item: "How often do you leak urine?" Potential correlates of 1-year incidence of UI included sociodemographic, behavioral, medical, physical, and psychosocial characteristics. The overall incidence of UI at 1 year was 17.4%. Incident UI was associated with age, baseline activity of daily living impairment, health-related quality of life (HRQoL), mean steps per day, and depressive symptoms. Multivariate logistic regression models revealed that improvement in physical performance score (odds ratio (OR) = 0.69, 95% confidence interval (CI) = 0.50-0.95) and high baseline physical (OR = 0.60, 95% CI = 0.40-0.89) and mental (OR = 0.62, 95% CI = 0.43-0.91) HRQoL were independently associated with lower rates of 1-year incident UI. An increase in depressive symptoms at 1 year (OR = 4.48, 95% CI = 1.02-19.68) was independently associated with a higher rate of incident UI. One-year UI incidence in this population of older urban Latino adults participating in a walking trial was high but was lower in those who improved their physical performance. Interventions aimed at improving physical performance may help prevent UI in older Latino adults. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society. Source

Ports 2013: Success Through Diversification - Proceedings of the 13th Triennial International Conference | Year: 2013
The City of Los Angeles Harbor Department (Harbor Department) has been a world leader at reducing the effects of seaport operations on the communities that surround the Port of Los Angeles (Port). The Harbor Department is in the process of installing ten megawatts (MW) of photovoltaic (PV) solar power as a means of reducing greenhouse gas emissions. This ten MW of zero-emissions power generation will be constructed within the Port's boundary. This paper presents the Harbor Department's successes and challenges associated with the implementation of its ten MW PV solar power program. This paper presents the criteria for successful evaluation and selection of potential sites for PV solar power systems (PV Systems), the installation of the Harbor Department's first MW, and the forging of an agreement with the City's utility agency to reduce up-front costs. This paper also describes the challenges the Harbor Department has faced such as final site selection, design, permitting, construction, and commissioning as it works at installing its remaining nine MW. Given these challenges, the Harbor Department is exploring different technologies as an alternative to PV solar power to help it achieve its goal of ten MW of zero-emissions power generation in a faster and more cost-effective way. © 2013 American Society of Civil Engineers.

This study intends to provide a simplified analytical model of the laterally confined concrete filled steel tube (CCFT) column system which adopts carbon-fiber-reinforced polymer (CFRP) jackets in order to make up for major defects of the traditional concrete filled steel tube (CFT) column system. This CCFT analytical model, by adding one additional parameter for CFRP confinement to the CFT column analytical solution, is greatly simplified and expedites the analytical processes to explain the stress-strain relationship of the CCFT column system. In the study, several types of the CCFT column systems with different parameters are analyzed by the proposed simplified analytical model and its associated numerical program (USC-CFT). To verify the accuracy of the analytical model, this study compares the load-strain relationship calculated by USC-CFT both to the experimental results conducted by the traditional method and to the results calculated by the computer-aided finite element method (FEM) analysis method. This study shows equilibrium conditions, deformation compatibilities, constitutive models, and an analysis procedure used in the proposed simplified analytical solution and presents finite element models and analysis procedure used in FEM analysis. © 2010 ASCE.

« Cost-effective iron-nitrogen-doped graphene fuel-cell catalyst approaches performance of platinum | Main | UCR team advances direct production of chemical and fuel precursors in yeast » The City of Los Angeles is introducing the Go LA app, powered by Xerox, a solution that integrates all the available methods of getting around the second largest metro area in the United States. Unlike other efforts to improve the daily commute, the Go LA app captures the full range of transportation options and computes the shortest, cheapest, and most sustainable way to get to your destination. The app aggregates and calculates the time, cost, carbon footprint, and health benefits from walking, biking, driving your own car, parking, taking public transit, as well as the emerging private transportation options—such as Lyft, Zipcar, FlitWays and Uber—giving users a variety of ways to reach their destination. Discovering user needs for combining public and private transportation options, Xerox researchers designed and delivered this smart city solution. There are individual apps for public transit, car sharing and other transportation options but the Go LA app captures the array of options in a hyper-local way, mixing and matching both public and private transportation options. Beyond the seamless travel experience for citizens, Go LA will help the city glean important information they can use to advance their transportation systems. The app takes an individual’s destination and desired arrival time, and calculates the different routes available, categorized by “sooner,” “cheaper,” and “greener.” Details provided include length of trip, price, number of calories burned, and how much carbon dioxide is released into the air, allowing users to choose the best option to meet their needs. As the app learns more about its user’s individual travel preferences, it will eventually recommend and highlight personalized commuting options. Customers can also save trips they take often, like from home to work, in their “My Rides” area of the app. The destination and preferred travel mode data is anonymously shared with the city to deliver insights on how people travel around the region. This information is useful as cities look to redesign and update the travel systems while optimizing capital spend. Xerox is working with its partners to integrate booking and payments into the app so users can coordinate their entire trip with a single click of a button. Future versions of the app will also include ridesharing so that users can carpool with people traveling in the same direction, as well as destination parking information. After enough data is collected, users will also be able to create a profile where they can set goals related to their personal fitness, financials and time, and track them within the app. The Go LA app is now available for iOS and Android systems in the Apple and Google Play stores at www.golaapp.com. A customized version of this app will be rolled out by the City of Denver in February 2016.
