H-removable sequences, for arbitrary H, under &Lambda^* construction are presented here. In the first part we investigate Neighborhood Distinct (ND) graphs and ask some natural questions concerning disconnected H and H complement. In the second part, we introduce property * and investigate graphs that satisfy property *. Consequently we find $H$-removable sequences for all graphs H with up to 6 vertices except for G60. G60 is the only graph with up to 6 vertices for which neither it nor its complement satisfies property *. The last part of our work focuses on good and bad copies of arbitrary graphs $H$ and how to interchange from one to the other. The number of ways to count all possible copies of H in H_{pn} ^ &Lambda^* is also presented via examples.

abstract: Although much has been done to examine the relationship between unemployment and crime, little consideration has been given to the impact neighborhood-level factors such as informal social control may have on the strength of unemployment as a predictor of crime. The present study seeks to fill this gap by assessing whether the declining crime rates over a period of surging unemployment under the financial crisis are due to unchanged levels of informal social control. To examine these relationships, the present study utilizes data from Uniform Crime Reports (UCR), calls for service to the police, and the United States Census and American Community Survey. These data are longitudinal in nature covering the period 2007-2011 and are all related to Glendale, Arizona. The results indicate that the financial crisis predicts lower rates of property crimes as well as lower rates of calls for service relative to UCR crimes. Additionally, the present study finds that unemployment is a significant predictor of increases in UCR property crime, UCR violent crime, and engagement in each of my measures of informal social control. / Dissertation/Thesis / Masters Thesis Criminology and Criminal Justice 2016

abstract: A genetically engineered line of human induced pluripotent stem cells was used to study the effects of gene expression on cell fate. These cells were designed to activate expression of the gene GATA6 when exposed to the small molecule doxycycline. This gene was chosen because it plays an important role in the developmental biology stages of liver formation. Because of the way the cells were engineered, a given population would have a heterogeneous expression of GATA6 because each cell could have a different copy number of the exogenous gene. This variation allows for the differentiation of multiple cell types, and is used to grow liver organoids. The early liver organoid samples were studied via immunofluorescent staining, imaging, and quantitative image analysis. It was originally hypothesized that absolute gene expression was not the most important factor in determining cell fate, but relative gene expression was. This meant that the spatial location of the cells and their local environment were critical in determining cell fate. In other words, the level of GATA6 of a cell is important, but so is the level of GATA6 in the surrounding cells, or neighborhood, of that cell. This hypothesis was analyzed with the creation of various Neighborhood Impact Factor (NIF) methods. Multiple time points of growth were analyzed to study the temporal effect, in addition to the gene expression and NIF influence on a cell’s fate. Direct gene expression level showed correlation with certain cell fate markers. In addition to GATA6 expression levels, NIF results from early and late time point experiments show statistical significance with relatively small neighborhood radii. The NIF analysis was useful for examining the effect of neighboring cells and determining the size of the neighborhood – how far cells influence one another. While these systems are complex, the NIF analysis provides a way to look at gene expression and its influence in spatial context. / Dissertation/Thesis / Powerpoint presentation used in the defense. / Masters Thesis Bioengineering 2017

abstract: Ethnic enclaves, or neighborhoods with high ethnic densities, have been linked with positive health outcomes and lower crime rates. Using data from the Pathways to Desistance project, this study tested whether neighborhood Latino concentration prospectively predicted re-offense rates among a sample of Mexican American juvenile offenders (n = 247). Further, I tested whether the effect of neighborhood Latino concentration on re-offense was moderated by ethnic identity, Mexican orientation, and generation status. Covariates included demographics and risk factors for offending. Results showed that neighborhood Latino concentration, ethnic identity, Mexican orientation, and generation status were not predictive of re-offense rates. Gender, risk for offending, and time spent supervised during the follow-up period predicted re-offense rates one year later. The results highlight the importance of risk assessment for this high risk group. / Dissertation/Thesis / Masters Thesis Psychology 2018

Each year 700,000 to 800,000 parolees are released prison and are returned to the community (Durose, Cooper, & Snyder 2014; Porter, 2011; West, Sabol, Greenman, 2010), of whom approximately two-thirds will be reincarcerated within the three years following their releases (Durose et al., 2014). Although, scholars have pointed to parolees’ needs of services and resources (Hipp, Petersilia, & Turner, 2010), the majority of the literature has been limited to the examination of individual-level predictors of parolee outcomes. The current study aims to extend the parolee literature by identifying whether or not neighborhood disadvantage, mobility, and local institutions (i.e., churches, service providers) have an effect on parolee outcomes. To examine these effects, data on 3,077 parolees living within 209 Census block groups across Philadelphia, Pennsylvania were obtained from the Pennsylvania Department of Corrections (PA DOC) and the Pennsylvania Board of Probation and Parole (PBPP). Furthermore, parolee outcome data were disaggregated by the behavior resulting in reincarceration [i.e., the commission of a new crime (CPV), technical parole violation (TPV)], as well as the length of time between release from prison and reincarceration. A series of multilevel models (HLM) were conducted to examine the effects of neighborhood-level and individual-level predictors of parolee reincarceration, as well as how these effects differed for CPVs versus TPVs, and varied across time. Based on results from the analyses, parolee outcomes were to some extent effected by neighborhood context and institutions (i.e., Evangelical Protestant churches, service providers). Additionally, neighborhood-level and individual-level effects varied based on the reason for reincarceration, and the amount of time that passed between release from prison and reincarceration. Lastly, although DOC referred service providers did not have a direct effect on parolee reincarceration, there were significant interaction effects with disadvantage, such that the effects of DOC service providers decreased the odds of reincarceration in more disadvantaged neighborhoods. The conditional effects of DOC service providers by level of neighborhood disadvantage highlights the need for service providers within such communities. Further investigation of neighborhood context, and the placement of much needed resources in communities where parolees reside, may be advantageous in increasing success amongst parolees.

The purpose of this study was to estimate disparities in late human immunodeficiency virus (HIV) diagnosis and all-cause mortality among varying populations of HIV-positive Latinos, and to identify neighborhood-level predictors. Florida HIV surveillance data for years 2000–2011 were merged with 2007–2011 American Community Survey (ACS) data. Multilevel logistic regressions were used to estimate adjusted odds ratios (aOR) for late HIV diagnosis (acquired immunodeficiency syndrome within 3 months of HIV diagnosis). Multilevel weighted Cox regressions were used to estimate adjusted hazard ratios (aHR) for mortality. Of 5522 Latinos diagnosed 2007–2011, males were at increased odds of late diagnosis compared with females (aOR 1.37, 95% confidence interval [CI] 1.13-1.67). Associated factors included residing in the lowest quartile of neighborhood education for females, and in the 3 highest quartiles of unemployment for males. Foreign-born compared with United States (US)-born Latinos were also at risk (aOR 1.24, 95% CI 1.08-1.42). Among foreign-born, residing in areas with

The Greater Vancouver Region is in an era of growth, fundamental change, and reexamination of regional and local quality of life. Within this context, the complete community policies of the Livable Region Strategic Plan have been developed to help achieve a region where human community flourishes within the built and natural environment. At the same time as these policies respond to change, they also demand significant alterations to community and regional priorities and practices. Accepting and pursuing complete community objectives of compactness, diversity and choice in existing suburban communities represents particular challenges. While regional policy reflects a general appreciation of this fact, understanding these challenges from a local perspective is essential to successfully weaving complete community goals into the existing regional fabric, and is the problem addressed by this thesis. Through both a literature review and case study approach, the research sought to identify the factors which support and constrain progress towards more complete communities through local planning in established neighbourhoods. The thesis focuses on the case study of the Lynn Valley community planning process in order to explore how the local perspective might modify inherently regional complete community goals and expectations. The study concludes that achieving a balance between regional goals and local interests is most critical in the Greater Vancouver metropolitan setting. The Lynn Valley case suggests that factors affecting community planning outlined in the literature are realistic and valid in practice. It further suggests that the prospects for achieving complete communities in established neighbourhoods will be influenced by local perspectives on: growth, change, aging in place, and a spirit of fairness in accepting change among local communities. The complete community vision resonates at the local level. Complete community objectives and strategies may be accepted locally to the degree they are seen as a means to achieve community aspirations and improve the quality of life of residents over their life cycle. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

The current study was a cross-sectional examination of data collected during an HIV risk reduction intervention in south Florida. The purpose of the study was to explore the relationships between neighborhood stress, parenting, attitudes, and adolescent sexual intentions and behavior. The Theory of Planned Behavior was used as a model to guide variable selection and propose an interaction pathway between predictors and outcomes. Potential predictor variables measured for adolescents ages 13-18 (n=196) included communication about sex, parent-family connectedness, parental presence, parent-adolescent activity participation, attitudes about sex and condom use, neighborhood disorder, and exposure to violence. Outcomes were behavioral intentions and sexual behavior for the previous eight months. Neighborhood data was supplemented with ZIP Code level data from regional sources and included median household income, percentage of minority and Hispanic residents, and number of foreclosures. Statistical tests included t-tests, Pearson’s correlations, and hierarchical linear regressions. Results showed that males and older adolescents reported less positive behavioral intentions than females and adolescents younger than 16. Intentions were associated with condom attitudes, sexual attitudes, and parental presence; unprotected sexual behavior was associated with parental presence. The best fit model for intentions included gender, sexual attitudes, condom attitudes, parental presence, and neighborhood disorder. The unsafe sexual behavior model included whether the participant lived with both natural parents in the previous year, and the percent of Hispanic residents in the neighborhood. Study findings indicate that more research on adolescent sexual behavior is warranted, specifically examining the differentials between variables that affect intentions and those that affect behavior. A focus on gender and age differences during intervention development may allow for better targeting and more efficacious interventions. Adding peer and media influences to the framework of attitudes, parenting, and neighborhood may offer more insight into patterns of adolescent sexual behavior risk.

abstract: Objective: Migration to the United States (U.S.) has been associated with food insecurity and detrimental changes in diet quality. How these changes affect women in context of their neighborhood food environment has not been thoroughly explored. This study aimed to assess if food security is associated with diet quality and to explore if perceived food availability moderates this purported association in a sample of Mexican immigrant women. Methods: Mexican-born women (n=57, 41±7 years) residing in the U.S. for more than 1 year self-reported food security status, monthly fast-food frequency, and their perception of fruit, vegetables, and low-fat product availability within their neighborhood via survey. Diet was assessed using the Southwest Food Frequency Questionnaire to estimate intake of fruit, vegetables, salty snacks, sugar, and healthy eating index (HEI)-2015 score. Bivariate correlations assessed the relationships between study variables. Independent samples t-tests compared dietary outcomes between women classified as food secure (n=41; high or marginal food security) and food insecure (n=16; low or very low food security). A moderation analysis assessed the effect of the perception of the neighborhood food environment on the relationship between food security and HEI-2015 score. Results: Fifty four percent of participants worked full time and 42% had a monthly household income <$2,000. Time residing in the U.S. was 20±9 years. Relative to women classified as food secure, participants experiencing food insecurity had lower HEI-2015 (61±8 vs. 66±6; p=0.03). Albeit not significantly different, women experiencing food insecurity reported lower intake of fruit (236±178 vs. 294±239 g), vegetables (303±188 vs. 331±199 g), and salty snacks (6±5 vs. 8±10 g), as well as higher intake of sugar (99±55 vs. 96±56 g) and fast food (2.5±2.5 vs. 1.8±1.7 times per month); p>0.05 for all. Among women experiencing food insecurity, there was a trend for a lower perception of neighborhood fruit, vegetable and low-fat product availability being associated with lower HEI-2015 scores (54±6) relative to those who perceived moderate (63±6) or high (65±8) neighborhood availability of those foods (p=0.07). Conclusions: HEI-2015 scores were associated with participants’ food security status. Findings suggest a need for better understanding of how neighborhood food availability may affect diet quality among Mexican immigrant women experiencing food insecurity. / Dissertation/Thesis / Masters Thesis Nutrition 2020
