The purpose of this study is to introduce the design and early implementation results of Choice Neighborhoods(Choice) initiative, which is the most recent version of public housing policies in the United States designed and implemented under the Obama administration. The Choice initiative aims to support a wide range of strategies locally driven to address problems in disadvantaged neighborhoods with an emphasis on a comprehensive approach to transforming those neighborhoods. In this study, first, I briefly review the history of public housing policies since 1937, particularly focusing on limitations of HOPE VI(Housing Opportunity for People Everywhere) projects to understand the context behind the advent of the program. Second, I introduce the overall design of the Choice program and point out how this programs' design differs from previous public housing programs by reviewing the literature on federal guidelines for the Choice program. This study particularly focuses on introducing social services given to existing residents in public housing and their neighborhoods in redevelopment processes. These social services are intended to address poverty-related problems that public housing residents often confront, to help them break out of the cycle of poverty, and to minimize the negative impacts of relocation triggered by redevelopment. Third, to examine how this program has been implemented and has revealed limitations so far, I review an interim evaluation report based on five cities. This study ends with discussing policy implications for public housing providers and housing policy-makers in South Korea.

This study examines why families move to neighborhoods at different levels of income. By analyzing a survey dataset of homeowners who sold and bought a house in 1999 in Franklin County, Ohio, in USA on their mobility decisions, this study examined the factors associated with cross-income residential location decisions. I categorized both survey respondents and neighborhoods into low-, middle-, and high-income levels and ran multinomial logit analyses for each of the low-, middle-, and high-income family groups to examine why families moved to neighborhoods at different levels of income. The analysis suggests that middle-income families moved to high-income neighborhoods because of school reputation and moved to low-income neighborhoods because of investment purposes.

The objective of this paper is to use Geographical Information Systems for identifying Digital Divide in Riyadh Neighborhoods, Saudi Arabia. Geo-database was created that includes Streets, Neighborhoods, ICT Access Data and Coverage Map for Riyadh. We used QGIS and overlay for analysis, intersection selected as tool for this paper. The results indicate that after analyzing the use of information communication technology in all regions of the Kingdom it turns that Riyadh, Ash Sharqiyyah and Makkah in average with percentage 50%, While Al Jawf, Al Madinah, and Najran are the least with percentage 42%. Then we focused on Riyadh to analyze the digital divide because it is the capital of Saudi Arabia and occupations the highest percent of communications towers in the KSA due to population density. Regarding coverage of the 4G, the neighborhoods at the center have recorded very high coverage score. While neighborhoods at the edges of the city have low values of coverage score. Same for 3G, it is more intense in the center and the coverage percentage is higher than 4G. For 2G we found it had the highest coverage compared to 3G or 4G

The main object of this paper is to prove several inclusion relations associated with (j, ${\delta}$)-neighborhoods of various subclasses defined by Salagean operator by making use of the familiar concept of neighborhoods of analytic functions. Special cases of some of these inclusion relations are shown to yield known results.

This study aims to understand whether the effect of poverty is translated to adolescents' mental health though their exposure to violence, which is aggravated by the dangerous environments of the neighborhoods. For this purpose, the study analyzes whether poor adolescents tend to reside on neighborhoods with toxic environments, and whether living in the disadvantageous neighborhood causes the poor adolescents to experience greater violence victimization and fear of violence, and eventually, greater depression and anxiety. The study utilizes secondary analysis of longitudinal data of the Korea Youth Panel Survey. Structural Equation Modeling is used as an analysis method. The study results reveals that poverty has both direct and indirect effects on the level of adolescents' symptoms of depression and anxiety. Especially, poverty affects adolescents' depression and anxiety indirectly through increasing the possibility to reside in more dangerous neighborhoods. Explaining more in detail, living in dangerous neighborhoods seems to expose adolescents more to violence and fear of violence in the neighborhoods and this experience increases the level of depression and anxiety. The study argues that the negative effects of poverty on adolescents should be examined from the view of neighborhood environments. Finally, the study discusses the importance of increasing neighborhood competency as practice and policy implication.

In this paper, we introduce the concepts of pre convexity neighborhoods, c-concave functions. We study some properties for c-convex functions, and characterize c-convex functions and c-concave functions by using the preconvexity neighborhoods.

The purpose of this work was to apply geographical information system (GIS) for geostatistical analyzing by selecting a semi-variogram model to quantify the spatial correlation of the population distribution with residential neighborhoods in the both sides of Mosul city. Two hundred and sixty-eight sample sites in 240 ㎢ are adopted. After determining the population distribution with respect to neighborhoods, data were inserted to ArcGIS10.3 software. Afterward, the datasets was subjected to the semi-variogram model using ordinary kriging interpolation. The results obtained from interpolation method showed that among the various models, Spherical model gives best fit of the data by cross-validation. The kriging prediction map obtained by this study, shows a particular spatial dependence of the population distribution with the neighborhoods. The results obtained from interpolation method also indicates an unbalanced population distribution, as there is no balance between the size of the population neighborhoods and their share of the size of the population, where the results showed that the right side is more densely populated because of the small area of residential homes which occupied by more than one family, as well as the right side is concentrated in economic and social activities.

Most of the Korean apartment complexes are considered as gated communities having characteristics such as self-sufficiency in service provision, self-governance and exclusiveness. Today the exclusionary features of apartment complexes are reinforced by a new practice of erecting gates against pedestrians in addition to the existing walls without considering implication of the practice over neighborhoods. Three groups of residents, those who live in low-rise residential areas without walls, apartment complexes with walls and apartment complexes with walls and gates were surveyed to measure the impact of the new exclusionary practice of gated communities on social sustainability of neighborhoods. Gates turn out to improve social sustainability indicators related to life quality but lower social cohesion of neighborhoods by lowering inclusiveness indicator considerably. The new apartment complexes with increased exclusiveness shake the established order of co-existence between low-rise residential areas and apartment complexes and strengthen spatial and social segregation within neighborhoods.

By making use of the familiar concept of neighborhoods of analytic functions, we prove several inclusion relationships associated with the (n, ${\delta}$)-neighborhoods of certain subclasses of p-valent analytic functions of complex order with missing coefficients, which are introduced here by means of the Saitoh operator. Special cases of some of the results obtained here are shown to yield known results.

In the present investigation, by making use of the familiar concept of neighborhoods of analytic and multivalent functions, we prove several inclusion relations associated with the (n, ${\delta}$)-neighborhoods of certain subclasses of analytic functions of complex order, which are introduced here by means of the Al-Oboudi derivative. Several special cases of the main results are mentioned.
