The Neighborhood and Home Environments: Disparate Relationships with Physical Activity and Sedentary Behaviors in Youth” Annals of Behavioral Medicine

To increase participation in physical activity, it is important to understand the factors associated with a child’s choice to be physically active or sedentary. The neighborhood and home environments may be related to this choice. To determine whether the neighborhood environment or number of televisions in the home environment are independently associated with child physical activity and television time. The associations of the neighborhood and home environments on active and sedentary behaviors were studied in 44 boys and 44 girls who wore accelerometers and recorded their television watching behaviors. Neighborhood environment variables were measured using extensive geographic information systems analysis. Hierarchical regression analyses were used to predict physical activity after controlling for individual differences in age, socioeconomic status, percentage overweight, and time the accelerometer was worn in Step 1. Sex of the child was added in Step 2. A neighborhood design variable, street connectivity, accounted for an additional 6% (p <or= .01) of the variability in physical activity in Step 3. A block of variables including a measure of neighborhood land use diversity, percentage park area, and the interaction of Percentage Park Area x Sex then accounted for a further 9% (p <or= .01) of the variability in physical activity in Step 4. Increased access to parks was related to increased physical activity in boys but not in girls. The number of televisions in the home accounted for 6% (p <or= .05) of the variability in television watching behavior. Neighborhood environment variables did not predict television watching that occurs in the home. The neighborhood environment is more strongly associated with physical activity of boys than girls. Sedentary behaviors are associated with access to television in the home environment. To promote physical activity in children, planners need to design environments that support active living and parents should limit access to television viewing in the home.

Association of access to parks and recreational facilities with the physical activity of young children

Abstract: Objective.To determine associations of the neighborhood and home television environments with young children’s physical activity.Method.32 boys and 27 girls age 4 to 7 years wore accelerometers for 3 weekdays and 1 weekend day. The number of televisions in the home and television watching of the child were monitored using TV Allowance™units for 3 weeks. A geographic information system was used to measure neighborhood environment variables.Results.Hierarchical regression analysis was used to predict physical activity, initially controlling for sex, age, socioeconomic status, adiposity,and child television watching in step 1. In step 2, the number of televisions did not significantly increase the amount of variability accounted for in the prediction of physical activity. In step 3, housing density and the interaction of housing density by sex accounted for an incremental 12%(p<0.05) of the variability and in step 4 percentage park plus recreation area accounted for a further 10% (p<0.05) of the variability. Greater housing density predicted increased physical activity of boys, but not girls.Conclusion.Neighborhoods with increased proximity between homes and a greater proportion of park area are associated with greater physical activity in young children

Integrating ‘Big Data’ into the Analysis of the Dynamic Spatial Patterns of Hotel Development

The spatio-temporal relationship between tourism product similarity and spatial proximity has not been adequately studied empirically because of data and methodological limitations. New forms of data available at high temporal frequencies and low levels of spatial aggregation, together with large commercial data and expanding computational ability allow a variety of theories, old and new to be explored and evaluated more meticulously and systemically than has been possible hitherto. This study uses spatial visualization and data harvesting to synthesize a variety of data for exploring the evolution of hotel clusters and co-location synergies in US cities. The findings question the reliability of the current data to be used for identifying and analyzing the formation of tourist destination clusters and their dynamics. We conclude that synthesizing social media and large commercial data can generate a more robust database for research on tourism development and planning and improving opportunities for the examining spatial patterns of tourism activities. We also devise a protocol to combine ‘social media’ sources with big commercial sources for tourism
development and planning, and eventually other sectors.

Municipal property acquisition patterns in a shrinking city: Evidence for the persistence of an urban growth paradigm in Buffalo, NY

The purpose of this article is to examine municipal property acquisition patterns in shrinking cities. We use data from the City of Buffalo’s municipal
property auction records to analyze the spatial distribution of properties offered for sale in its annual tax foreclosure auction. In addition to these data, we examine demolition and building permit records. Our analysis suggests that cities like Buffalo follow strategies based on an urban growth paradigm when responding to abandonment. This paradigm operates under the assumption that growth is a constant and urban development is only limited by fiscal constraints, underdeveloped systems of urban governance, environmental degradation, and resistance by anti-growth coalitions. We recommend that planners in shrinking cities de-emphasize growthbased planning and focus on rightsizing strategies. These strategies are based on
the assumption that growth is not a constant. Consequently, urban revitalization is concentrated in a smaller urban footprint.

Housing abandonment and demolition: Exploring the use of micro-level and multi-year models

Policies focusing on enforcing property code violations and the improvement of vacant properties are argued to be more efficacious than demolition policies to fight urban blight. This study applies parcel level data to a multi-year hybrid modeling structure. A fine-grained analysis is conducted on the dynamic patterns of abandonment and demolition for a unique period of four years before and after the City of Buffalo’s stepped-up demolition efforts. Results showed that proximity to vacant and abandoned properties, sustained over the years, had the greatest impact on the possibility of a property being abandoned. The second greatest positive impact on property abandonment was small lot front size. Results also showed that neighborhood vacancy density had the greatest negative impact on surrounding housing sales prices over the years. There was no significant impact of demolition on housing sales prices. These findings suggested that the City should aim to have more incentive programs that are tailored to control the number of vacant properties, rather than focusing primarily on demolition-oriented programs.

Neighborhood characteristics and the location of HUD subsidized housing in shrinking cities: An analysis to inform anchor-based urban revitalization strategies

This article focuses on the manner in which affordable housing fits into anchor-based strategies for urban revitalization. It involves quantitative analysis of the location of existing HUD-subsidized housing in relation to neighborhood characteristics. The goal of the article is twofold. First, we examine the degree to which neighborhood characteristics associated with neighborhoods of opportunity correlate with the location of HUD-subsidized housing in shrinking cities. Second, we make recommendations for more equitable approaches to anchor-based urban revitalization. Our analysis uses a unique database developed to measure neighborhood characteristics in shrinking US cities. Our findings suggest that the location of affordable housing is not correlated with proximity to institutional and neighborhood amenities, where anchor-based revitalization is targeted. As a result, we make recommendations to link future affordable housing siting to anchor-based strategies for inner-city revitalization.

Neighborhoods of Opportunity: Developing an Operational Definition for Planning and Policy Implementation

This article synthesizes existing literature to examine the emerging concept of neighborhoods of opportunity and places it in the context of past efforts to define neighborhood opportunity. Place-based and people-based approaches to urban revitalization and community development are linked to this concept. The place-based approach focuses on promoting inner-city revitalization in order to create neighborhoods of opportunity and the people-based approach focuses on connecting people to opportunities that already exist in the regions where they live. These approaches are
examined in relation to how they influence emerging models for siting affordable housing in both distressed inner-cities and more opportunity rich suburbs that surround them. The article concludes with recommendations for a new tiered approach to place-based and people-based strategies for affordable housing siting in core city and regional contexts
