Looking For Better: A History Of Black Southern Migrations, Selena Sanderfer Doss Jan 2021

Looking For Better: A History Of Black Southern Migrations, Selena Sanderfer Doss

Midwest Social Sciences Journal

A broad overview of migrations affecting black southerners is presented, including the Atlantic slave trade, the domestic slave trade, colonization movements to Sierra Leone and Liberia, the Exoduster movement, the Great Migration, and the Return South migration. Emigrants convey their experiences and motivations through testimonies and personal accounts. Surviving the trauma of forced migrations, black southerners organized numerous migration movements both outside and within American polities in search of better opportunities. In the late 20th century, black southerners also initiated a return migration to the American South and have since achieved notable socioeconomic and political progress.

The Stain Of A Criminal Label: Post-Release Stigmatization And Its Effects On Reintegration And Recidivism Among Ex-Offenders, Ashlee N. Quinn-Hogan Jan 2021

The Stain Of A Criminal Label: Post-Release Stigmatization And Its Effects On Reintegration And Recidivism Among Ex-Offenders, Ashlee N. Quinn-Hogan

Sociology Publications

The successful reintegration of ex-offenders into the community is a primary factor in reducing recidivism and protecting the public. However, successful reintegration is often hard to come by. Prior research has examined the ways in which the stigmatic labelling of ex-offenders disrupts their successful re-entry into the community. Further, studies have shown that the stigmatic labelling of ex-offenders by the community plays a prominent role in offender recidivism. The present study examines this prior research and explores how gender, age, race/ethnicity, and class determine the extent of stigmatization that offenders experience. I conclude that some marginalized groups, such as women, …

What Do We Know About Senior Citizens As Cybervictims? A Rapid Evidence Synthesis, Laura Huey, Lorna Ferguson Jan 2021

What Do We Know About Senior Citizens As Cybervictims? A Rapid Evidence Synthesis, Laura Huey, Lorna Ferguson

Sociology Publications

Internet-based victimization of senior citizens is an important potential threat of growing social, economic, and public policy interest. Given this, we sought to examine whether the existing research base could be used to formulate sound public policy in this area. To do so, we conducted a rapid evidence synthesis and assessment of the research literature from 2010-2020 surrounding three central organizing themes: cyber-related harms, responses and strategies, and prevention programs and solutions. Results reveal that there is an insufficient research base, lack of diverse research topics, and shortage of research beyond that of which is exploratory in nature. However, our …

Decolonizing Vawa 2021: A Step In The Right Direction For Protecting Native American Women, Tara N. Richards, Sheena L. Gilbert, Emily M. Wright Jan 2021

Decolonizing Vawa 2021: A Step In The Right Direction For Protecting Native American Women, Tara N. Richards, Sheena L. Gilbert, Emily M. Wright

Criminology and Criminal Justice Faculty Publications

The Violence Against Women Act (VAWA) (1994) was a hallmark legislation aimed at combating violence against women. While violence against women is a national issue that affects women of all race/ethnicities, it affects Native American women the most, as Native women experience the highest rates of violence. Violence against Native women is rooted in colonization because it decreases the power of tribal government, diminishes tribal sovereignty, and devalues Native Americans, which in turn leaves Native women more vulnerable to victimization. As such, amendments to VAWA must take particular action on violence against Native women, including actions that support decolonization. The …

Visa Fraud In The Commercial Sex Market In The United States: An Overview, Youngbee Dale Jan 2021

Visa Fraud In The Commercial Sex Market In The United States: An Overview, Youngbee Dale

Dignity: A Journal of Analysis of Exploitation and Violence

This paper describes various fraudulent visas used by criminals operating in the U.S. sex market. Studies show that many foreign women exploited through commercial sex rely on visa brokers to enter the U.S. However, scholars have not investigated various visa brokers and the techniques they use to bring foreign women into U.S. prostitution as a whole. Therefore, this paper aims to provide an overview of the different types of fraudulent visas and criminal techniques used in the U.S. sex market. In doing so, this paper relies on both primary and secondary sources, such as interviews with both survivors and U.S. …

“Basic Stuff I Should Know About My Kids, I Don’T Know”: Incarcerated Mothers’ Perception Of Incarceration’S Effects On Mother-Child Relationships, Narissa Haakmat Jan 2021

“Basic Stuff I Should Know About My Kids, I Don’T Know”: Incarcerated Mothers’ Perception Of Incarceration’S Effects On Mother-Child Relationships, Narissa Haakmat

Online Theses and Dissertations

Tougher sentencing policies have resulted in a dramatic increase in the jail and prison populations in the United States over the past few decades. The number of women who are spending time behind bars have vastly increased as a result of this. Despite increased interest in this area of research, a variety of questions remain as to how women experience incarceration. Most women who are incarcerated are mothers, but few criminologists have explored how imprisonment affects motherhood and mothers’ perception of the mother-child relationship during incarceration. The research presented here contributes to this body of literature by exploring the effects …

Forgotten In Local Jails: A Carceral System Created To Fail Women., Hayley Jackey Jan 2021

Forgotten In Local Jails: A Carceral System Created To Fail Women., Hayley Jackey

Online Theses and Dissertations

The United States has seen an influx of incarcerated women since the 1980s with a 750% increase between 1980 and 2017. There is a substantial amount of literature about how women experience prison and the unique challenges they face as they reenter society such as motherhood, previous abuse, mental health, and housing. Conclusions drawn suggest that the current structure fails to prepare women for a society that denounces women who have been incarcerated. What is less known is how this research translates to the jail environment. For reasons to be discussed, it is likely that local jails are even less …

Through A Lens Of Therapeutic Jurisprudence: A Case Study Of The Children’S Court Drug Court In Perth, Suzanne Ellis Jan 2021

Through A Lens Of Therapeutic Jurisprudence: A Case Study Of The Children’S Court Drug Court In Perth, Suzanne Ellis

Theses: Doctorates and Masters

The Children’s Court Drug Court (CCDC) has operated for 20 years in Perth as an alternative Court for drug-using young offenders who present at the Children’s Court. Despite the CCDC’s relative longevity, researchers have examined neither the inner workings of the Court nor the experiences of its actors. The current study aimed, not to evaluate the CCDC, but to identify measures needed to refine CCDC processes to enhance the experiences and outcomes of young people who participate in the CCDC. It argues that despite the CCDC’s foundations in contentious therapeutic jurisprudence principles, on balance, the actors – young people, their …

The Court Is In Recession: On The Implications Of The Covid-19 Pandemic For Indigent Defense Spending, Andrew L. B. Davies, Victoria M. Smiegocki, Hannah E. Hall Jan 2021

The Court Is In Recession: On The Implications Of The Covid-19 Pandemic For Indigent Defense Spending, Andrew L. B. Davies, Victoria M. Smiegocki, Hannah E. Hall

Other Publications

What is the likely effect of the recession brought on by the COVID-19 pandemic on indigent defense budgets in the United States? To look forward, we look backward. We examine data on county-level spending on indigent defense in Texas during the Great Recession of 2007–2009. Redistributive policies—those which use taxpayer funds to support individuals who themselves pay little or no tax—are particularly susceptible to cuts during times of fiscal stress. Yet our analysis shows indigent defense policy, measured in terms of spending and access to counsel rates, was generally stable through the Great Recession years, even in counties hit hardest. …

American Epidemic: The Societal And Multi-Generational Impacts Caused By The Mass Incarceration Of Women In The United States, Jessica Younts Jan 2021

American Epidemic: The Societal And Multi-Generational Impacts Caused By The Mass Incarceration Of Women In The United States, Jessica Younts

Theses and Dissertations

This study examined the social impacts of incarcerating women, specifically mothers, as well as the far-reaching collateral consequences that the mass incarceration of women in the United States has on formerly incarcerated women’s successful reintegration back into society and analyzed how the harsh policies that exist detrimentally impact family members and society as a whole. This study revealed several themes that show the far reaching damage incarceration itself has on women and their families and provides a more comprehensive analysis of the incalculable costs of mass incarceration. By raising awareness to the long-term impact on society, this research can provide …

Cultivation Theory: Media Effects Toward Consumer Evaluations Of The Criminal Courts, Lindsey Dale Elliott Jan 2021

Cultivation Theory: Media Effects Toward Consumer Evaluations Of The Criminal Courts, Lindsey Dale Elliott

Murray State Theses and Dissertations

A substantial body of literature connects media effects to consumer perceptions of the criminal justice system. Research on the topic of cultivation theory has highlighted that an increased fear of crime within the general populace, due to an exaggeration of violence and criminal activity in the mass media, has spurred increased support for punitive policing, harsher sentencing, and positive feelings toward capital punishment. However, no research exists to explicate the cultivation of consumer perceptions toward the criminal courts. This study examines the impact of media consumption through television, the internet, and social media on consumer evaluations of the criminal courts. …

Exploring Group-Threat And Police-Involved Homicide : A Spatial Analysis Of Police Involved Homicide In Us Counties, Kyle Demori Maksuta Jan 2021

Exploring Group-Threat And Police-Involved Homicide : A Spatial Analysis Of Police Involved Homicide In Us Counties, Kyle Demori Maksuta

Legacy Theses & Dissertations (2009 - 2024)

The recent advent of the Black Lives Matter movement has reinvigorated criminological inquiry into police violence. Recent advances in spatial analysis have opened new opportunities for understanding the spatial relationship between social structure and police violence. Spatial analysis is both statistically and substantively important to our understanding of police-involved-homicide (PIH), yet few studies have attempted to marry recent advances in spatial econometrics to this topic. The current study introduces spatial Durbin modeling (SDM) as a particularly useful approach to studying the spatial relationships between variables associated with group threat theory and PIH. Previous research has demonstrated the connections between group …

Longitudinal Examination Of Contextual Risk, Promotive Factors, And Psychosocial Functioning Using Structural Equation Modeling With A Sample Of Serious Adolescent Offenders, Daniel J. Knauer Jan 2021

Longitudinal Examination Of Contextual Risk, Promotive Factors, And Psychosocial Functioning Using Structural Equation Modeling With A Sample Of Serious Adolescent Offenders, Daniel J. Knauer

Legacy Theses & Dissertations (2009 - 2024)

Mental health problems, including substance use problems, are more prevalent among adolescent criminal offenders than among the general population and are associated with an elevated risk of re-offending. It is important to understand what factors are associated with serious adolescent offenders’ future mental health and re-offending outcomes to promote their positive development. This study examined potential mechanisms behind established relationships between risk factors for mental health and criminal offending and psychosocial outcomes while integrating ecological theory and a risk and protective framework. To do this, a mediation model was examined using structural equation modeling in which contextual risk was hypothesized …

Roaring Tiger Or Bounce Tigger? : Examining Corruption Seriousness Perception In China From A Socio-Cultural Perspective, Yunhan Zhao Jan 2021

Roaring Tiger Or Bounce Tigger? : Examining Corruption Seriousness Perception In China From A Socio-Cultural Perspective, Yunhan Zhao

Legacy Theses & Dissertations (2009 - 2024)

Recent years have witnessed a steadily increasing scholarly interest in perceptions of corruption, particularly in terms of level and prevalence. However, previous studies have largely overlooked perceived seriousness as another unique dimension of corruption perception. Furthermore, previous studies seeking causes of corruption perception have failed to consider cultural factors at either the individual or aggregate level as potential predictors. To fill the gap, the current dissertation employs the 2014 Chinese Family Panel Studies and other relevant data to explore the relationships between corruption seriousness perception and cultural factors. This dissertation strategically examines two individual cultural attachments (i.e., Confucianism and Legalism …

Bio-Spatial Policing In Theory And Practice: Examining Impacts And Resistance Through Mobilities And Children's Everyday Life, Emily Kaufman Jan 2021

Bio-Spatial Policing In Theory And Practice: Examining Impacts And Resistance Through Mobilities And Children's Everyday Life, Emily Kaufman

Theses and Dissertations--Geography

Despite decades of reforms and technological innovations, increasing evidence shows that state securitization disproportionately harms already racially, spatially, and socio-economically marginalized communities. My research investigates uneven impacts of state securitization, from punitive welfare programs to school surveillance to policing. Across sites, I focus on scales, voices and the everyday lived experiences often left out of scholarly discourse and sensational media. In the current climate of growing awareness and scholarship on police violence, my dissertation addresses three less-studied areas: 1) the interplay between racial, gendered, spatial, and technified police practices; 2) how these practices impact the everyday lives of those racially …

Murders In The German Sex Trade: 1920 To 2017, Manuela Schon, Anna Hoheide Jan 2021

Murders In The German Sex Trade: 1920 To 2017, Manuela Schon, Anna Hoheide

Dignity: A Journal of Analysis of Exploitation and Violence

This research report is the result of collecting and evaluating data on cases of homicides and attempted homicides in the German sex trade from 1920-2017. The findings show violence against prostituted women and the attitudes of the sex buyers who commit most of the violent acts against the women. The report discusses the media coverage of murder cases, complication of cases, and a critique of methods of criminal evaluation by the police. From 1920 to 2017, 272 victims of murder and attempted murder were identified. Liberalization of prostitution occurred in 2002. From then until 2017, there is a decrease in …

Constitutional Pandemic Surveillance, Matthew B. Kugler, Mariana Oliver Jan 2021

Constitutional Pandemic Surveillance, Matthew B. Kugler, Mariana Oliver

Journal of Criminal Law and Criminology

How do people view governmental pandemic surveillance? And how can their views inform courts considering the constitutionality of digital monitoring programs aimed at containing the spread of a highly contagious diseases? We measure the perceived intrusiveness of pandemic surveillance through two nationally representative surveys of Americans. Our results show that even at the height of a pandemic people find surveillance for public health to be more intrusive than surveillance for traditional law enforcement purposes. To account for these strong privacy concerns, we propose safeguards that we believe would make cell phone location tracking and other similar digital monitoring regimes constitutionally …

Neither “Post-War” Nor Post-Pregnancy Paranoia: How America’S War On Drugs Continues To Perpetuate Disparate Incarceration Outcomes For Pregnant, Substance-Involved Offenders, Becca S. Zimmerman Jan 2021

Neither “Post-War” Nor Post-Pregnancy Paranoia: How America’S War On Drugs Continues To Perpetuate Disparate Incarceration Outcomes For Pregnant, Substance-Involved Offenders, Becca S. Zimmerman

Pitzer Senior Theses

This thesis investigates the unique interactions between pregnancy, substance involvement, and race as they relate to the War on Drugs and the hyper-incarceration of women. Using ordinary least square regression analyses and data from the Bureau of Justice Statistics’ 2016 Survey of Prison Inmates, I examine if (and how) pregnancy status, drug use, race, and their interactions influence two length of incarceration outcomes: sentence length and amount of time spent in jail between arrest and imprisonment. The results collectively indicate that pregnancy decreases length of incarceration outcomes for those offenders who are not substance-involved but not evenhandedly -- benefitting white …

"Defund The (School) Police"? Bringing Data To Key School-To-Prison Pipeline Claims, Michael Heise, Jason P. Nance Jan 2021

"Defund The (School) Police"? Bringing Data To Key School-To-Prison Pipeline Claims, Michael Heise, Jason P. Nance

Journal of Criminal Law and Criminology

Nationwide calls to “Defund the Police,” largely attributable to the resurgent Black Lives Matter demonstrations, have motivated derivative calls for public school districts to consider “defunding” (or modifying) school resource officer (“SRO/police”) programs. To be sure, a school’s SRO/police presence—and the size of that presence—may influence the school’s student discipline reporting policies and practices. How schools report student discipline and whether that reporting involves referrals to law enforcement agencies matters, particularly as reports may fuel a growing “school-to-prison pipeline.” The school-to-prison pipeline research literature features two general claims that frame debates about changes in how public schools approach student discipline …

Community-Informed Relationship Violence Intervention In A Highstress, Low-Income Urban Context, Tara N. Richards, Christopher M. Murphy, Lisa J. Nitsch, Angelique Green-Manning, Ann Marie Brokmeier, Adam D. Lamotte, Charvonne N. Holliday

Criminology and Criminal Justice Faculty Publications

To evaluate the effectiveness of the House of Ruth Maryland’s Gateway Project, a community-informed and oppression-sensitive relationship violence intervention program (RVIP; commonly labeled “batterer intervention”), designed for a predominantly low-income, racial minority population residing in a high-stress urban context. Method: Propensity score matching with data on 744 male program participants (89% Black; 59% unemployed; 76% on probation) was used to compare recidivism rates for those who did, and did not, complete the intervention program. The propensity score matching created comparison groups (n = 216 per group) with very similar distributions on 28 balancing factors. Results: During the year after program …

Comparing 911 And Emergency Hotline Calls For Domestic Violence In Seven Cities: What Happened When People Started Staying Home Due To Covid-19?, Tara N. Richards, Justin Nix, Scott Mourtgos, Ian Adams Jan 2021

Comparing 911 And Emergency Hotline Calls For Domestic Violence In Seven Cities: What Happened When People Started Staying Home Due To Covid-19?, Tara N. Richards, Justin Nix, Scott Mourtgos, Ian Adams

Criminology and Criminal Justice Faculty Publications

We examine changes in help-seeking for domestic violence (DV) in seven U.S. cities during the COVID-19 pandemic. Using Bayesian structural time-series modeling with daily data to construct a synthetic counterfactual, we test whether calls to police and/or emergency hotlines varied in 2020 as people stayed home due to COVID-19. Across this sample, we estimate there were approximately 1,030 more calls to police and 1,671 more calls to emergency hotlines than would have occurred absent the pandemic.Inter-agency data analysis holds great promise for better understanding localized trends in DV in real time. Research-practitioner partnerships can help DV coordinated community response teams …

Acid Attacks In India: A Socio-Legal Report, Vidhik Kumar Jan 2021

Acid Attacks In India: A Socio-Legal Report, Vidhik Kumar

Dignity: A Journal of Analysis of Exploitation and Violence

India has the highest number of acid attacks globally every year, and despite the actions taken by the Indian Government and the Supreme Court of India, the crime is on the rise. This increase can be attributed to the patriarchal ideology that is prevalent in India and to India’s inadequate legal system, which does not deliver efficient remedies to the victims. This article will discuss the prevalence of acid attacks in India, motives behind the attacks, consequences on victims, and shortcomings in measures adopted to prevent the crime and provide justice to victims.

Effects Of States’ Laws On Youth Physical Activity Participation And Obesity Prevalence, Chae Young Chang Jan 2021

Effects Of States’ Laws On Youth Physical Activity Participation And Obesity Prevalence, Chae Young Chang

Midwest Social Sciences Journal

The alarming prevalence of obesity and lack of physical activity among adolescents led to immediate policy action to address these concerns. Accordingly, many states introduced and enacted their own legislation to encourage physical activity in schools. Few studies have explored the effectiveness of the new legislation, however, especially at the state level. To answer the fundamental question of whether policy is effective and to describe the varying effects of state obesity policies, this study analyzed the Youth Risk Behavior Surveillance System from 2007 to 2017. Using the difference-in-differences method, this study found that legislative efforts to encourage physical activity had …

Profitable Retail Customer Identification Based On A Combined Prediction Strategy Of Customer Lifetime Value, Yinglu Sun, Dong Cheng, Subir Bandyopadhyay, Wei Xue Jan 2021

Profitable Retail Customer Identification Based On A Combined Prediction Strategy Of Customer Lifetime Value, Yinglu Sun, Dong Cheng, Subir Bandyopadhyay, Wei Xue

Midwest Social Sciences Journal

As a fundamental concept of customer relationship management, customer lifetime value (CLV) serves as a crucial metric to identify profitable retail customers. Various methods are available to predict CLV in different contexts. With the development of consumer big data, modern statistics and machine learning algorithms have been gradually adopted in CLV modeling. We introduce two machine learning algorithms—the gradient boosting decision tree (GBDT) and the random forest (RF)—in retail customer CLV modeling and compare their predictive performance with two classical models—the Pareto/NBD (HB) and the Pareto/GGG. To ensure CLV prediction and customer identification robustness, we combined the predictions of the …

Re-Spatializing Gangs: An Exponential Random Graph Model Of Twitter Data To Analyze The Geospatial Distribution Of Gang Member Connections, Ryan J. Roberts Jan 2021

Re-Spatializing Gangs: An Exponential Random Graph Model Of Twitter Data To Analyze The Geospatial Distribution Of Gang Member Connections, Ryan J. Roberts

Political Science & Geography Faculty Publications

Gang studies often use location-based approaches to explain gang members’ interconnectedness. Although this perspective remains consistent with the proximity principle that the smaller the geographic space, the greater the likelihood of observing connections between individuals, location-based studies limit our understanding of gang member connections to narrowly defined geographic spaces at specific points in time. The advent of social media has re-spatialized gang member interconnectedness to unbounded geographic spaces, where the preservation of online activity can extend indefinitely. Despite having an online presence, most research examining the digital footprint of gangs tends to be descriptive. This study collects Twitter data to …
