La decisión de investigar una epidemia puede estar determinada por varios factores importantes. La limitaciones de recursos financieros y humanos o personal experto pueden impedir hacer investigaciones; aunque estas limitaciones no siempre son insuperables. Existen oportunidades de entrenamiento y asistencia en investigaciones de epidemias, disponibles, por parte de diferentes agencias estatales y federales, como el CDC (Centers for Disease Control and Prevention, Centros de Control de Enfermedades y Prevención de los Estados Unidos). Aunque los costos directos de una investigación...

National Evidence Regarding Behavior and Physical Activity in New Urbanist Neighborhoods

2012

Although proponents have emphasized new urbanism’s ability to reduce automobile dependence, increase walking, and improve the health of its residents, there is a paucity of research to support these claims. The authors surveyed residents of 34 neighborhoods in 12 U.S. states to examine whether the travel behavior and physical activity of new urbanist neighborhood residents differed from their conventional suburban counterparts. They used a matched-pair design in which each new urbanist neighborhood was matched with a conventional suburban neighborhood in the same municipality....

Validity of Secondary Retail Food Outlet Data

Improving access to healthy foods is a promising strategy to prevent nutrition-related chronic diseases. To characterize retail food environments and identify areas with limited retail access, researchers, government programs, and community advocates have primarily used secondary retail food outlet data sources (e.g., InfoUSA or government food registries). To advance the state of the science on measuring retail food environments, this systematic review examined the evidence for validity reported for secondary retail food outlet data sources for characterizing retail food environments.

The Construct Validity of the Tennis Self-Concept Scale II

Rodriguez, D
1998

This dissertation study focused on the structure of self-concept in the sport of tennis. A new scale was designed to assess tennis self-concept across five core tennis skills, an assortment of ancillary skills, fitness, psychological skills, and general tennis. The Tennis Self-Concept Scale II (TSCS II) was tested for construct validity with a sample of 225 college students participating in undergraduate tennis classes. Confirmatory factor analysis was employed to test the internal structure of the TSCS II. A comparison was made between two competing theoretical models of self-concept: A...

Commercial Vehicle Parking in California: Exploratory Evaluation of the Problem and Solutions

California is home to major international ports in Long Beach, Los Angeles, and Oakland, as well as the second largest border crossing between Mexico and the U.S. California’s highways are critical commercial links from these ports of entry to the nation and carry more commercial vehicle truck traffic than any other state in the U.S. Given the high volume of truck travel in California, it is not surprising that there is a serious shortage of truck parking in the state. This shortage negatively impacts economic productivity, roadway safety, air quality, and public health. This report begins...

Can Neighborhood Design Encourage Physical Activity?

Although new urbanism continues to gain popularity worldwide, many of its effects remain unexamined. If neighborhood design can support or impede active lifestyles, we hypothesize that residents of new urbanist neighborhoods will exhibit higher levels of physical activity than residents of conventional communities. Following a quasi-experimental research design, this study evaluates physical activity patterns of residents in two distinctly designed neighborhoods, a new urbanist and a conventional suburban neighborhood in a central North Carolina community. The two neighborhoods were...

Physical activity participation for youth and adults is suboptimal in North Carolina. There is growing interest among policy makers to promote physical activity, yet research in this area is limited. The North Carolina Physical Activity Policy Research Center was established in 2004 to conduct research on physical activity and policy. This cross-disciplinary center brings together faculty and researchers from the University of North Carolina School of Public Health and the College of Arts and Sciences. Current projects include understanding and documenting polices that affect walking...

Can New Urbanism Encourage Physical Activity?: Comparing a New Urbanist Neighborhood with Conventional Suburbs

Rodriguez, DA
Khattak, AJ
Evenson, KR
2007

If neighborhood design can support or undermine active lifestyles, then residents of new urbanist neighborhoods can be expected to exhibit higher levels of physical activity than residents of conventional communities. This study compared various measures of physical activity for residents of a new urbanist neighborhood to those for a group of conventional suburban neighborhoods in central North Carolina, finding no statistically significant differences, even after adjusting for individual and household characteristics. However, we did detect differences in where people were...

Las poblaciones de osos andinos en Colombia están drásticamente amenazadas y sugieren de manera crucial la aplicación de alternativas de conservación que sean acordes a los problemas específi cos de cada ejemplar. El uso de estrategias de enriquecimiento ambiental, es una práctica que ha ido cogiendo fuerza y se ha vinculado de manera importante en las propuestas de rehabilitación y liberación de osos mantenidos bajo condiciones de cautiverio. Se ha establecido que mediante el uso de estas técnicas, se puede modifi car el comportamiento de un individuo y que al establecer un cronograma de...
