Perceptions of the Seriousness of Crime and Attitudes Regarding Criminal Justice Issues: An Analysis of the 1982 American Broadcasting Corporation's News Poll of Public Opinion on Crime

This study deals with the analysis of public opinion about crime and attitudes regarding criminal justice issues along two major dimensions. The first part concerns how respondents rank crime among a list of nine social problems (unemployment, high interest rates, inflation, crime, the high cost of living, moral decline, taxes, dissatisfaction with the government, and Reagan). The second dimension examines some research questions. These are whether there was any association between the respondents' perception of crime trends and each of the following: demographic background, neighborhood safety, the death penalty, gun ownership, frequency of locking doors, avoidance of teenagers, and the evaluation of police job performance; and also whether there was any association between the respondents' victimization experience and seriousness of crime and police job performance. The data were obtained from the archives of the Inter-University Consortium for Political and Social Research in Michigan.

Framing a Sacred Fight: Framing Analysis and Collective Identity of the #noDAPL Movement (open access)

Framing a Sacred Fight: Framing Analysis and Collective Identity of the #noDAPL Movement

The #noDAPL movement was an Indigenous-led environmental social movement occurring between 2015 and 2017, in which the Standing Rock Sioux and other American Indian tribes comprising the Oceti Sakowin garnered support to oppose the 1,172-mile Dakota Access Pipeline. Pipeline opponents agreed that the pipeline's construction posed a threat to the health and safety of tribal members and other residents of the area and that the pipeline's path crossed previously-designated tribal treaty boundaries, compromising tribal sovereignty. In this body of work, I utilize Facebook data from the Sacred Stone Camp Facebook page to locate and identify collective action frames and core framing tasks, adhering to social movement framing theory. Further, I provide insight into the movement's most used collective action frames and how their use enabled to movement to maintain occupation at protest camps along the Missouri River, garner resources from participants and gain international social support. I also draw on concepts of pan-Indianism and supratribalism to discuss indigenous collective identity, as well as concepts like relational values and Indigenous traditional knowledge to better assess the nuances of Indigenous environmental activism and how this movement evoked discussions of modern day settler colonialism.

Organizational Identity, Health Identity, and Motivation: a Symbolic Interactionist Approach to the Understanding of Heath Behaviors in Work Settings (open access)

Organizational Identity, Health Identity, and Motivation: a Symbolic Interactionist Approach to the Understanding of Heath Behaviors in Work Settings

Identity is an important determinant of behavior. This paper proposed an identity model as one way of understanding those factors related to the perceived probability or willingness of a worker to participate in health promotion programming at the worksite. Part of a larger study on employee wellness, this study took place in the municipal complex of a small city in the southeastern United States. A stratified cross sectional sample of 150 employees was selected utilizing a systematic random sampling methodology. Structured interviews were conducted with 129 participants resulting in a response rate of 92% after adjusting for those people no longer employed by the city. In order to test the identity model developed by this author, descriptive analysis, simple multiple regression analysis and path analysis were utilized. The dependent variable, perceived willingness to participate in health promotion programming, was examined in relationship to commitment to one's health identity, commitment to one's organizational identity, tendency to comply with health initiatives, and the forms of supervisory power utilized to enact employee compliance. The descriptive analysis revealed that subjective health status is moderately and positively associated with commitment to one's health identity, that individuals can be strongly committed to a negative/destructive health identity, …

Artificial Intelligence at Home: Alexa, Are You Influencing My Family?

The purpose of this research is to measure the social shifts that take place in a home where artificial intelligent (AI) devices like Echo Dot and Google Home are fully integrated into their everyday life. Research is currently limited, being that the widespread use of these devices is roughly seven years old. Three main outcomes of this study were related to how often Alexa is being used in homes to solve everyday problems, the lack of overall privacy and security concerns users had, and the level of integration into the home as a member of the family. Some limitations and challenges are my ability to compare the households before and after installing these devices in the home; pinpointing when and where the device is used (i.e., room placement); collecting data on whether the device is used often or sparingly; and the depth of interactions these families actually have with the device on a whole. The broader implications behind the increased integration of AI devices is centered around health, labor, social inequality and ethics.

Intersectional Analysis of Perceived Racism as a Determinant of Children's Mental Health

Youth in the United States are experiencing a steep increase in mental health issues. Concurrently, unique political, economic and social dynamics in the U.S. make the circumstances of nonwhite children's mental health partially contingent on experiences of racism. In this study, I examine the relationship between racial minority children's mental health and perceived racism, while also examining the moderating effects of gender on this relationship. I first review prior research which suggest that racism is a salient determinant of several health outcomes among racial minorities and racial minority children, including depression and anxiety. I then review research on both gender and racial socialization and posit possible implications of these differentials on mental health. Considering both the racialized and gendered factors contributing to youth's mental health outcomes, this study fills a gap in previous research by exploring the differences by gender and race in the effect of perceived racism on children's mental health. I use data from the National Survey of Children's Health from 2016 to 2019. Using average marginal effects, calculated from a series of logistic regression models predicting depression, anxiety, behavioral and emotional problems, I find support for previous research which suggests that perceived racism predicts poor mental health …

"God will get me through": African American women coping with breast cancer and implications for support groups. (open access)

"God will get me through": African American women coping with breast cancer and implications for support groups.

This research examines the coping processes of African American women with breast cancer and how those processes relate to low usage of cancer support groups by these women. Prior coping research has utilized predominantly White samples. The limited research on African American coping responses is conflicting and characterized by small samples and non-probability sampling techniques. In this study, 26 respondents from Central and North Texas metropolitan areas were interviewed, including 9 key informants, 9 African American breast cancer survivors, and 8 White survivors. The data suggest that African American and White women cope with breast cancer in significantly different ways. Culture appears to account for the differences. All African American breast cancer survivors identified faith as their primary coping strategy. In contrast, only half of the White survivors claimed faith as their primary coping strategy, but like the other White survivors, tended to rely on multiple coping strategies. The African American survivors conceptualized God as an active member of their support network. Most prayed for healing, and several attributed examples of healing to God's intervention. The White survivors found God's presence in the actions of other people. They prayed for strength, peace, and courage to endure the illness. The use …

Socioeconomic Status and Prosperity Belief in Guatemala (open access)

Socioeconomic Status and Prosperity Belief in Guatemala

A popular belief in the exploding Pentecostal movement in the global South is the idea that if an individual has enough faith, God will bless them with financial prosperity. Although historically Pentecostalism has been identified as a religion of the poor, this study examines recent arguments that the current Pentecostal movement in Guatemala is a religion of the socially mobile middle and elite classes. Data from the Pew Forum on Religious and Public Life’s 2006 survey Spirit and Power: Survey of Pentecostals in Guatemala is used to conduct a logistic regression, in order to measure the effects of socioeconomic status on adherence to prosperity belief. Results suggest that, contrary to the current literature on Guatemalan Pentecostalism, prosperity belief is not necessarily concentrated among the upwardly mobile middle and upper classes, but rather is widely diffused across social strata, and in particular, among those that have lower levels of education. These findings have implications for the study of Pentecostalism in Guatemala and in the global South in general.

Contraceptive Choice among American Teenage Women: a Test of Two Models Based on the Dryfoos Strategy (open access)

Contraceptive Choice among American Teenage Women: a Test of Two Models Based on the Dryfoos Strategy

Teenage pregnancy rates in the U.S. are among the highest in the world for industrialized countries. The generally accepted reason is not that American teenagers are more sexually active but that they contracept less than do teenagers in other industrialized countries. This dissertation reports on a study that was undertaken for two purposes. One purpose was to develop and test two models of contraceptive choice among American teenagers: a "likelihood-of-use" model to predict the likelihood of sexually active teenagers' using contraception, and a "medical-or-nonmedical" model to predict whether teenagers who use contraception are likely to use medical or nonmedical methods. The second purpose was to explore the level of support for the two models among black and white teenagers separately. The theoretical underpinning of the models is value-expectancy theory. The models' exogenous variables are based on the prevailing strategy for preventing teenage pregnancy among American teenagers, a strategy initially advocated by Joy G. Dryfoos. The strategy involves the use of access-to-contraception programs, educational programs, and life options programs. The data used in the study were on 449 subjects drawn from the 1979 National Survey of Young Women, a probability-sample survey of women in the U.S. aged 15-19. The subjects were …

Use of Preventive Screening for Cervical Cancer among Low-income Patients in a Safety-net Healthcare Network

This study is a secondary analysis of survey data collected in fall 2000 from patients of a safety-net hospital and its eight community health outreach clinics in Fort Worth, Texas. The study examined three objectives. These include explaining the utilization of Pap smear tests among the sample who were low-income women, by ascertaining the determinants of using these services. Using binary logistic regressions analyses primarily, the study tested 10 hypotheses. The main hypothesis tested the race/ethnicity/immigration status effect on Pap smear screening. The remaining hypotheses examined the effects of other independent/control variables on having a Pap smear. Results from the data provide support for the existence of a race/ethnicity/immigration status effect. Anglos were more likely to have had a Pap smear, followed by African Americans, Hispanic immigrants, and finally, by Hispanic Americans. The persistence of the race/ethnicity/immigration status effect, even when the effects of other independent/control variables are taken into account, may be explained by several factors. These include cultural differences between the different groups studied. The race/ethnicity/immigration status effect on Pap smear screening changed with the introduction of age, usual source of care, check-up for current pregnancy, and having multiple competing needs for food, clothing and housing into the …

Acceptance and use of corporal punishment among parents of biologic and non-biologic children. (open access)

Acceptance and use of corporal punishment among parents of biologic and non-biologic children.

Objective: Differences between biologic and non-biologic parents' acceptance and use of ordinary corporal punishment and use of explaining/reasoning as a disciplinary tool are examined from a sociobiological theoretical perspective. Method: Cross tabulations are used on data from a national survey conducted by the Gallup Organization in 1995. Results: Contrary to predictions, differences between biologic and non-biologic parents' acceptance of ordinary corporal punishment and the use of explaining/reasoning are not statistically significant. In addition, biologic parents are found to use ordinary corporal punishment significantly more often than non-biologic parents. Conclusions: The sociobiological theoretical perspective likely underestimates the influence of culture and social structure on parent-child interactions.

Prosperity Belief and Liberal Individualism: A Study of Economic and Social Attitudes in Guatemala (open access)

Prosperity Belief and Liberal Individualism: A Study of Economic and Social Attitudes in Guatemala

Globalization has facilitated the growth of “market-friendly” religions throughout the world, but especially in developing societies in the global South. A popular belief among these movements is prosperity belief. Prosperity belief has several characteristics which make it compatible with liberal individualism, the dominant value in a globalized society. At the same time, its compatibility with this value may be limited, extending only to economic liberalism, but not to liberal attitudes on social issues. Data from the Pew Forum on Religious and Public Life’s 2006 survey Spirit and Power: Survey of Pentecostals in Guatemala is used to conduct a quantitative analysis regarding the economic and social attitudes of prosperity belief adherents in Guatemala in order to examine the potential, as well as the limits, of this belief’s compatibility with liberal individualism. Results suggest that support for liberal individualism is bifurcated. On one hand there is some support for the positive influence of prosperity belief on economic liberalism in regards to matters of free trade, but on the other hand, prosperity belief adherents continue to maintain conservative attitudes in regards to social issues. As prosperity belief and liberal individualism continue to grow along global capitalism, these findings have implications for the future …

Relationship between the amount of parental supervision time and child delinquency. (open access)

Relationship between the amount of parental supervision time and child delinquency.

This study assesses the relationship between parental supervision and children's delinquency. Data used in this study came from interviews with 99 parents from the Denton city area of Texas in 2003. A probability sample of 53 was contacted by way of randomly selected residential telephone numbers. In addition, 46 parents were non-randomly selected. Parents were asked about how much time they spent supervising and engaging in activities with their children and whether or not the oldest child exhibited delinquent behavior such as fighting, playing hooky, and being sent to detention or the principal's office. The study found that the more time parents spend in supervision and in engaging activities with their daughters, the less likely these children were to exhibit delinquent behavior. This was consistent with previous research. However, the level of delinquency of boys increased with the increase in the amount of parental supervision time, especially by fathers.

Alcohol Use among the Elderly in Edmonton, Alberta: a Multivariate Analysis (open access)

Alcohol Use among the Elderly in Edmonton, Alberta: a Multivariate Analysis

A model of social stressor variables, social integration variables and demographic control variables was tested to assess their impact on alcohol use among the elderly. A secondary analysis of a survey on alcohol use among the elderly in Edmonton, Alberta, Canada, was conducted to test the major hypotheses of the study. Contingency table analysis, using gamma and partial gamma as correlation coefficients, was utilized in the data analysis. The first hypothesis, in regard to the positive relationship of social stressors with alcohol use, was confirmed. The best predictors of alcohol use among the social stressor variables were usual occupation, length of retirement, annual income, and subjective health status. The second hypothesis, that the social integration variables would be negatively related to alcohol use, received only moderate support. The results of the analysis indicated that six of the ten social integration variables were negatively related to alcohol use. Only three of these variables, retirement status, religious participation, and marital status, were statistically significant. Hypothesis three also was not confirmed. The introduction of the social integration variables did not substantially decrease the strength of the relationship between social stressors and alcohol use. Gender and age were also introduced as control variables for …

Assessing Social Determinants of Severe Mental Illness in High-Risk Groups

The primary objective of this research was to explore the impact of possible social factors on non-institutionalized adults 18 years of age or older residing in the United States who exhibited severe mental illness (SMI). A holistic sociological model was developed to explain SMI by incorporating elements of social learning theory, social disorganization theory, and gender socialization theory with social demographic factors. Based on the holistic sociological model, the following factors were investigated: demographic aspects of age, education, income and gender; gender socialization; influence of neighborhood area; social network influence based on communication and interaction among peers and family members; and socially deviant behaviors such as frequently smoking cigarettes, drinking alcohol and using drugs specifically marijuana. The impact of these factors on SMI was examined. A sample of 206 respondents drawn from National Survey on Drug Use and Health, 2003 was assessed. These respondents had answered all the questions related to SMI; social deviant behaviors; neighborhood environment; and communications among peers, family members and friends; and the other studied factors. Ordinary linear regression with interaction terms was employed as a statistical tool to assess the impact of social determinants on SMI. Being female, living a disorganized neighborhood, and frequent and …

Deviant Behavior Among Young Adults: Turkish Case with an Emphasis on Family Rituals, Self-esteem and Religiosity.

The conduct of young adults has long been a concern in societies. The primary objective of this study was to gain greater understanding of what influences the deviant behavior of young adults in Turkey. Factors assessed in their background included family rituals, self-esteem, religiosity and deviant behavior. It was expected that levels of family rituals, religiosity, self-esteem and other risk factors would be significantly different between incarcerated youth and youth not incarcerated. Overall, these higher levels of family rituals, religiosity, and self-esteem plus lower levels of other risk factors were expected to negatively affect young people's engagement in deviant behavior in Turkey. Walter Reckless' containment theory provided a framework for this study. The non-probability sample of Turkish youths consisted of 205 incarcerated respondents and 200 college students. Each responded to four survey instruments, the Family Rituals Questionnaire, the Culture Free Self-Esteem Inventory, the Religious Background and Behavior Questionnaire, and a Family Information Inventory. Data were gathered cross-sectionally from January through March of 2007. The incarcerated respondents significantly practices less family rituals and had lower levels of religiosity than the college students but they did not differ significantly on self-esteem. Furthermore, overall participation in family rituals was associated with decreased likelihood …

“What Are You?”: Racial Ambiguity and the Social Construction of Race in the Us

This dissertation is a qualitative study of racially ambiguous people and their life experiences. Racially ambiguous people are individuals who are frequently misidentified racially by others because they do not resemble the phenotype associated with the racial group to which they belong or because they belong to racial/ethnic groups originating in different parts of the world that resemble each other. the racial/ethnic population of the United States is constantly changing because of variations in the birth rates among the racial/ethnic groups that comprise those populations and immigration from around the world. Although much research has been done that documents the existence of racial/ethnic mixing in the history of the United States and the world, this multiracial history is seldom acknowledged in the social, work, and other spheres of interaction among people in the U.S., instead a racialized system based on the perception of individuals as mono-racial thus easily identified through (skin tone, hair texture, facial features, etc.). This is research was done using life experience interviews with 24 racially ambiguous individuals to determine how race/ethnicity has affected their lives and how they negotiate the minefield of race.

Energy Paths and Political Commitments: Their Roles in Environmental Inequality (open access)

Energy Paths and Political Commitments: Their Roles in Environmental Inequality

Decentralized renewable energy procurement has gained traction in recent years for its potential to alleviate rural energy poverty and environmental degradation in developing countries. Hence, this study investigates if deploying renewable energy can mitigate rural energy poverty in developing countries as often claimed. Because any energy regime cannot be initiated or sustained without the conviction of local political leaders, the study also evaluates the extent to which government investments in the development of renewable energy technologies and the energy sector, affect the environmental quality (i.e. greenhouse gas emissions) of developing countries. Energetic theory and environmental inequality constitute the key conceptual premises guiding this study. Ordinary least squares regression is utilized to analyze the relationship between key variables. The results reveal that as of 2010, use of renewable energy can indeed support rural electrification. Higher GNI per capita and use of conventional fuels are also positively related to rural electrification, all else equal. As for environmental degradation in 2005 and 2008, R&D investments actually tend to increase GHG emissions; procuring energy from either renewable or non-renewable sources is however, found to be environmentally detrimental, net of all other variables. Finally, some evidence is found for the role of aid funds and …

Unpacking Asylum: Participatory Online Platforms in the Information-Seeking Phase (open access)

Unpacking Asylum: Participatory Online Platforms in the Information-Seeking Phase

In the last few years, the world has been gripped by a crisis of forced migration and displaced persons. Being forced migrants, asylum-seekers are a unique and diverse population, originating from many countries with different backgrounds and experiences. This makes fulfilling the information needs of the asylum community difficult. Online participatory platforms, such as blogs and discussion forums, are flexible, adaptive information resources that could be used to meet the diverse needs of this population. In this study, I compare two online resources used by asylum-seekers, a blog and discussion forum, using social network analysis and topic modeling techniques. Through these analyses, I have determined the conversational archetype the best reflects both websites and discovered the information needs expressed and, in many cases, resolved through conversations in these online spaces. The core finding of this study is that providing direct access to an expert, such as through an interactive blog, promotes dialogue on a greater variety of topics and increases the likelihood of a thorough response. Furthermore, blog posts may inform participants' comments by providing them with the necessary vocabulary to participate fully in the online setting.

AIDS Preventative Behavior Among Taiwanese University Students (open access)

AIDS Preventative Behavior Among Taiwanese University Students

This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.

Exploratory Analysis of Social E-health Behavior

Extant literature has documented well that people seek health information via the internet as patients and consumers. Much less, however, is known about interaction and creation behaviors in the development of new online health information and knowledge. More specifically, generalizable sociodemographic data on who engages in this online health behavior via social media is lacking in the sociological literature. The term “social e-health” is introduced to emphasize the difference between seeking behaviors and interaction and creation behaviors. A 2010 dataset of a large nationally representative and randomly sampled telephone survey made freely available from the Pew Research Center is used to examine social e-health behavior according to respondents’ sociodemographics. The dependent variable of social e-health behavior is measured by 13 survey questions from the survey. Gender, race, ethnicity, age, education, and income are used as independent variables. Logistic regression analysis was used to determine the odds of engagement in social e-health behavior based on the sociodemographic predictors. The social determinants of health and digital divide frameworks are used to help explain why socioeconomic variances exist in social e-health behavior. The findings of the current study suggest that predictable sociodemographic patterns along the dimensions of gender, race, age, education, and income …

Access: Use of this item is restricted to the UNT Community
Using data from the Household Component of the 1996 Medical Expenditure Panel Survey, the study compares (1) the accessibility, and (2) the predictors of health care services utilization among African American and non-Hispanic White males, 18 to 65 years old in the United States. Using ANOVA procedure in comparing the means for use of physicians, hospitals, doctors, and difficulty obtaining care, seven hypotheses were tested in the study. First, it was hypothesized that African American men of working age will have less access to health care services (physicians, hospitals, and dentists), and be more likely to report having experienced delay or difficulty obtaining care, compared to non-Hispanic white males of working age. Second, it was hypothesized that, controlling for health status, African American men of working age will have less access to health care services (physicians, hospitals, and dentists), and will also be more likely to experience delay or difficulty obtaining care, than non-Hispanic white males. This was followed by the third hypothesis which compared utilization of physicians, hospitals, dentists, and difficulty obtaining care among African American and non-Hispanic white males, controlling for health status and insurance coverage (any insurance, private insurance, any public insurance, and Medicaid).
