A Longitudinal Examination of Risk Factors, Antisocial Outcomes, and Transition Patterns Across Bully Profiles

Bryson, Sara 01 January 2020 (has links) (PDF)
The current research focuses on the risk factors for bully profiles, antisocial behavior across profiles, and patterns of bullying behavior over the span of four school years. The sample was comprised of 1,817 middle school students from seven school districts. Latent profile analysis, multivariate regression techniques, and latent transition analysis were used to meet the five objectives of this study: 1) identify unique subgroups of youth based on responses to different bully experiences, 2) determine similarities and differences in risk factors that are associated with bully experiences, 3) examine antisocial behavior across identified bully profiles, 4) determine if membership in bully profiles is stable or changes over time, and 5) assess the similarities and differences in the risk factors associated with transition patterns over four time points. Results indicated that unique subgroups of youth exist based on bully perpetration and bully victimization experiences. Similarities and differences arose in the risk factors that were associated with bully experiences and transition patterns. However, across the identified bully profiles, antisocial behavior did not vary once time order was established. These results have important implications for research, practice, and policy, which are discussed.

A Spatiotemporal Examination of Crime Site Selection for Commercial Burglary and Street Robbery

Cowan, Devin 01 January 2023 (has links) (PDF)
The overall goal of this dissertation is to examine how the built and natural environment influences how potential criminals identify crime sites to offend within. Guided by the theoretical principles of crime site selection and crime pattern theory, this study specifically focuses on the crimes of street robbery and commercial burglary in three unique study locations—Atlanta, GA, Fayetteville, NC, and Rochester, NY. The data for this study were collected from multiple publicly available data repositories. Of these repositories, criminal incident data for the dependent variables were gathered from the National Policing Institute's Police Data Initiative. Data for the independent variables, which are representative of the built and natural environment, were collected from various open-source public and governmental agencies. To assess the influence of the built and natural environment on crime site selection, several techniques were employed. First, general spatial patterns were mapped using both kernel density estimation (KDE) and directional distribution analysis. Subsequently, temporal trends were identified by separating the data into several temporal units of analysis, including by meteorological season, weekday/weekend, and four-hour block increments. To assess multivariate relationships, two machine learning techniques were used: multivariate clustering and random forest classification. In alignment with prior literature, findings indicate that criminal incidents for both street robbery and commercial burglary cluster spatially and temporally. Of note, there are seasonal trends identified within the data, as well as trends relating to the time of day. Results from the multivariate clustering analysis reveal several unique spatial clusters of variables within each study location. The random forest classification and regression analysis rank ordered the importance of independent variables in their relationship to the criminal incidents in question. This ordering varied considerably depending on the temporal unit of analysis in question, which suggests the spatial predictors of street robbery and commercial burglary differ by season, weekday and weekend, and time of day. These results hold theoretical, methodological, and practical implications within the scope of environmental criminology.

Bias Among Forensic Document Examiners: A Need for Procedural Changes

Miller, L. S. 01 January 1984 (has links)
Questioned document examination, particularly handwriting/handprinting identification, lends itself readily to unintended bias on the part of the examiner. Questioned document examination is one of the few forensic science areas that depends primarily on a subjective analysis by the examiner. Most questioned document examiners attempt to render analyses as objectively as possible by using sophisticated measuring techniques. However, complete objectivity cannot be achieved because of the situation in which the document examiner is summoned for analyses, and the fact that most of the identification process involves a subjective opinion of the examiner. There exists some concern over the amount of unintended bias among document examiners. In any handwriting comparison, one can point out both similarities and dissimilarities of the writing habits. If the samples are pictorially similar, it becomes easier to point out similarities. A preconceived conclusion that 'the suspect wrote or did not write the document' based on the situation and social interaction finds an easier outlet when the samples are pictorially similar or dissimilar. There should be more than one sample of handwriting exemplars submitted for analysis. When possible, true examplars as well as request exemplars should be submitted to control for possible disguising of handwriting. By following these suggestions, a document examiner and submitting agency (police or attorney) can inhibit the amount of bias that may lead to erroneous conclusions by the examiner.

"Good OI' Boys" and the Chair: Death Penalty Attitudes of Policy Makers in Tennessee

Whitehead, John T. 01 January 1998 (has links)
This report is a summary of a survey of Tennessee chief prosecutors (district attorneys general), chief public defenders, and state legislators concerning their attitudes toward capital punishment. Global approval was compared with (1) approval when offered the options of life without parole and (2) life without parole and restitution to the victim's family. Additional items probed approval of capital punishment for specific subpopulations: juvenile, mentally ill, and mentally retarded offenders. Consistent with previous research, support for the death penalty declined when respondents were given the option of life without parole. A concluding note is offered calling for more complete research on the issue.

An Analysis of Juvenile Correctional Treatment

Lab, Steven P., Whitehead, John T. 01 January 1988 (has links)
The state of the evidence concerning correctional treatment prompts a vast array of differing opinions. One extreme position posits that “nothing works” while the other end of the continuum claims that some programs have very positive effects. The present study surveyed the professional literature appearing between 1975 and 1984 (inclusive) in order to evaluate the current state of knowledge on juvenile correctional treatment. The impact of treatment on recidivism was the primary consideration in a simple ballot-box analysis of reports published in professional journals. The results indicated that juvenile correctional treatment fared no better than in earlier reviews. In general, at least half of the studies reported negative or no impact on recidivism and many of the positive findings were based on dubious, subjective evaluations.

Examining Risk Factors of Juvenile Delinquency and the Predictive Validity of a Juvenile Risk Assessment Instrument Across Urban and Rural Communities

Vannan, Kelly 01 January 2021 (has links) (PDF)
Juvenile delinquency among the nation's youth is an ongoing concern. An essential task of juvenile justice workers is to identify and measure risk factors that impact a youth's likelihood of recidivating. The Florida Department of Juvenile Justice (FDJJ) utilizes the Positive Achievement Change Tool (PACT) to assess the risk for recidivism among all juveniles referred to the system. The current study examined how youths' level and types of risk, as well as the ability of the PACT to predict the odds of reoffending and the time to reoffend, vary across urban and rural communities. This study drew upon theories of social disorganization and collective efficacy (Raudenbush & Sampson, 1999; Shaw & McKay, 1942) and Andrews and Bonta's (2010) Risk-Need-Responsivity (RNR) model. Secondary data was used from 10,229 juvenile probationers in Florida to conduct bivariate analyses including chi-square tests of significance, independent samples t-tests, area under the curve estimations, multivariate logistic regression, and survival analyses. Results indicated that a greater proportion of urban youths than rural youths were rated at higher risk levels for recidivism. Of the eight types of risks examined, only past antisocial behavior, current antisocial peers, and current substance abuse varied significantly across community type. Also, a significant relationship was found between recidivism and community type. Finally, the PACT predicted both the odds of recidivism and time to recidivism more accurately for urban youths than for rural youths. The findings of this study may help guide juvenile justice practitioners in more accurately identifying risk factors and in determining whether one risk assessment instrument is sufficient for assessing juveniles from different types of communities.

Law Enforcement Motivations for Establishing Real-Time Crime Centers: A Mixed Model Study

Linton, Frank 01 January 2022 (has links) (PDF)
Law enforcement agencies across the United States are establishing real-time crime centers (RTCCs) at a rapid rate, yet research exploring the decisions to establish them is lacking. This study therefore attempts to fill that void by using a mixed methods approach to examine whether adaptive organizational theories, consisting of contingency theory (Lawrence & Lorsch, 1967; Woodward, 1965), resource dependency theory (Pfeffer & Salancik, 1978), and institutional theory (DiMaggio & Powell 1991; Meyer & Rowan, 1977), can be used to explain a law enforcement agency's decision to set up an RTCC. This cross-sectional mixed methods design comprised two different studies (Study 1 & Study 2). Study 1 consisted of a content analysis of newspaper articles (N = 235) that listed the terms "real-time crime center" or "real time crime center". The content analysis revealed that both resource dependency theory and contingency theory were likely factors for a law enforcement agency's decision to establish an RTCC. Study 2 included interviews of agency leaders of Florida law enforcement departments that had established an RTCC (N = 11) and those that had not (N = 2). A qualitative analysis of the interviews with agency leaders indicates that traditional organizational theories may not fully explain law enforcement agencies' adoption of RTCCs. The interviews partially confirmed the content analysis of newspaper articles while revealing a theme of front-line and mid-management influence on decision-making. This study found that internal lower-ranking "champions," not external forces, are the primary reason law enforcement agencies are establishing RTCCs, a term known as institutional entrepreneurship (DiMaggio 1988; Eisenstadt, 1980). This study is important because it provides a foundation for explaining why law enforcement agencies choose to set up RTCCs, a law enforcement organizational element whose establishment across the United States does not appear to be slowing anytime soon. This study also highlights an aspect of institutional theory not found in the criminal justice literature. Lastly, limitations and future directions for research are discussed.

Innovation Resistance? Understanding Officer Attitudes Toward Police Innovation

Smith, Justin 01 January 2022 (has links) (PDF)
Over the years, innovations such as community-oriented policing, problem-oriented policing, and crime analysis have helped police agencies control, reduce, and prevent crime and disorder, and improve police and community relations. However, research shows that some officers are resistant to using these innovations in practice. Few studies have examined the causal mechanisms behind innovation resistance. This doctoral dissertation details a study that utilized a mixed method approach to partially test a framework that encompassed two theories to explain officer resistance to innovation: The Model of Consumer Resistance to Innovation from the consumer psychology and marketing fields (Ram & Sheth, 1989), and the Monolithic Model of Police Occupational Culture (Paoline, 2003) from the police culture literature. The study was conducted at a midsize Central Florida police agency. The department recently introduced two new innovations, a community policing activity called the Community Interaction Project and an in-car computer system called Street Smart. The primary goal of the study was to examine officer attitudes toward these innovations using the theoretical framework. An Internet-based survey was disseminated to sworn staff (N = 263). In depth interviews were conducted with a sample of command staff and patrol officers (n = 19). Ordinary least squares multiple linear regression analysis of the survey results revealed that themes from the police occupational culture predicted innovation resistance barriers to the Community Interaction Project. The interviews revealed several additional themes that explain resistance to the Community Interaction Project and Street Smart. The dissertation concludes with a discussion of theoretical and methodological contributions to social science. Policy implications are provided for police practitioners. Limitations and future directions for study are also discussed.

The Expansion of School Resource Officers in a Florida County: A Mixed Methods Study

Soderstrom, Melanie 01 January 2022 (has links) (PDF)
In the aftermath of school shootings, policymakers presented the expansion of school resource officers (SROs) in the nation's schools as a method for keeping students safe. Recently, policing in the United States has come under increased scrutiny, and several school districts across the country cancelled their SRO contracts with law enforcement agencies. Notably, these contradictory decisions have been made with limited empirical knowledge surrounding, the roles, preparedness, and impact of SROs. A county in Florida substantially expanded its SRO program in the 2016-17 school year creating a new unit within the local sheriff's office and an opportunity to investigate these topics. A convergent parallel mixed methods design was applied to examine this new unit, consisting of a quantitative strand using interrupted time series analysis to assess the new program's effect on school-based arrests and Baker Act apprehensions, and a qualitative strand collecting and analyzing participant observations of training requirements and in-depth interviews with the SROs to explore their responsibilities, roles, and preparation for the position. Qualitative findings demonstrate that the primary role of the SROs is safety and security, while some also engage in a secondary role of engaging in positive interactions with the school community. Ambiguity exists surrounding execution of these roles, with the SROs relying a great deal on other relevant actors during decision-making. SROs identified the importance of careful selection for the position, training requirements are described, and problems with the training are identified. Contrary to this study's hypotheses, quantitative results show that the new unit did not have a statistically significant impact on overall school-based arrests, but disaggregating the data showed a significant impact on felony arrests. Similarly, there was no statistically significant impact on overall Baker Act apprehensions of students, however, there is preliminary evidence of an impact on elementary school-aged students.
