Problem-oriented approach to criminal investigation: implementation issues and challenges

Problem-oriented approach to criminal investigation: implementation issues and challenges

Date: August 2001
Creator: Ozeren, Suleyman
Description: As a proactive, information-based policing approach, problem-oriented policing emphasizes the use of crime analysis techniques in the analysis of the underlying causes of the problems that police deal with. In particular, analysis applications can be powerful tools for criminal investigation, such as crime reconstruction, profiling, IAFIS, VICAP, and CODIS. The SARA Model represents a problem-solving strategy of problemoriented policing. It aims to address the underlying causes of the problems and create substantial solutions. However, implementing problem-oriented policing requires a significant change in both the philosophy and structure of police agencies. Not only American policing but also the Turkish National Police should consider problem-oriented policing as an alternative approach for solving criminal activities.

An Analysis of the Effect of Environmental and Systems Complexity on Information Systems Failures

An Analysis of the Effect of Environmental and Systems Complexity on Information Systems Failures

Date: August 2001
Creator: Zhang, Xiaoni
Description: Companies have invested large amounts of money on information systems development. Unfortunately, not all information systems developments are successful. Software project failure is frequent and lamentable. Surveys and statistical analysis results underscore the severity and scope of software project failure. Limited research relates software structure to information systems failures. Systematic study of failure provides insights into the causes of IS failure. More importantly, it contributes to better monitoring and control of projects and enhancing the likelihood of the success of management information systems. The underlining theories and literature that contribute to the construction of theoretical framework come from general systems theory, complexity theory, and failure studies. One hundred COBOL programs from a single company are used in the analysis. The program log clearly documents the date, time, and the reasons for changes to the programs. In this study the relationships among the variables of business requirements change, software complexity, program size and the error rate in each phase of software development life cycle are tested. Interpretations of the hypotheses testing are provided as well. The data shows that analysis error and design error occur more often than programming error. Measurement criteria need to be developed at each stage of the ...

The uninvestigated factors: Dimensions of personality and psychopathology in sex offenders

The uninvestigated factors: Dimensions of personality and psychopathology in sex offenders

Date: May 2001
Creator: Briley, Josh
Description: Understanding the relation between personality characteristics, psychopathology, and sexual offenses can contribute to developing more effective treatment interventions. Previous research with sex offenders has focused on general personality traits or inconsistently classified sex offenders based on psychopathology. It was hypothesized that combining personality and psychopathological traits can assist in understanding sex offenders. The current study evaluated 88 male sex offenders in a court-mandated outpatient treatment program utilizing the NEO-PI-R and the MMPI-2. Three clusters of child molesters were examined for differences in personality characteristics and number of offenses. A second-order principle axis factor (PAF) analysis of personality and psychopathology traits revealed three factors: Psychological Distress, Excitement-Seeking, and Social Desirability. The potential clinical utility of these dimensions in predicting treatment compliance is examined.

Transnational Organized Crime and Destabilization in Democracies, Russian Organized Crime as Case Study

Transnational Organized Crime and Destabilization in Democracies, Russian Organized Crime as Case Study

Date: August 2001
Creator: Yasar, Muhammet Murat
Description: Transnational organized crime has been prevalent during the last century, but it recently has been recognized as a threat to the world order. Governments throughout the world, along with the intergovernmental organizations identified this phenomenon as a new threat to domestic and international security. This paper attempts to explain the impacts of transnational organized crime on the functioning of democratic societies by adopting the Russian Organized Crime as case study. The descriptive research with regard to definition, scope and organization of transnational organized crime, along with the objectives, limitations and methodology of this research will be included in the first chapter. Recent trends observed in organized crime`s character and the impact of organized crime on the political economies of democratic regimes will be contained in the following chapters. Pre-conditions for a broader response to transnational organized crime and conclusive remarks will be the context of the last chapter.

Media Influence on Executive Police Decision-Making: A Case Study of Police and Media Interaction During the Oklahoma City Bombing Investigation and Trials

Media Influence on Executive Police Decision-Making: A Case Study of Police and Media Interaction During the Oklahoma City Bombing Investigation and Trials

Date: May 2001
Creator: Bellew, Steven S.
Description: Because media influence public opinion, it is often surmised that media also influence the decisions of police executives. This exploratory case study examined the relationship between police and media during the Oklahoma City bombing investigation and subsequent trials of Timothy McVeigh and Terry Nichols. Findings indicate that media influence police executive decisions when police and media interact closely. It was found that during the Oklahoma City bombing investigation and trials, police on the outer perimeter were influenced most and police conducting the investigation or who were tasked to court room security were influenced the least. It was concluded, based on the consensus of respondents interviewed, that media do influence police executive decisions.

Comparison of GPS Point Selection Methods for GIS Area Measurement of Small Jurisdictional Wetlands

Comparison of GPS Point Selection Methods for GIS Area Measurement of Small Jurisdictional Wetlands

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Shelton, Michael
Description: U.S. Army Corps of Engineers (USACE) regulates fill of jurisdictional waters of the United States including wetlands. Recent USACE regulations set a threshold of impacts to wetlands at one-half acre. Impact area can be determined by Global Positioning System (GPS) measurement of wetland boundary and Geographic Information System (GIS) calculation of impact area. GPS point selection methods include (1) equal time interval, (2) transect and (3) intuition. Four two-acre shapes were measured with each GPS method and brought into GIS for area calculation. Analysis of variance and Root Mean Square Error analyses determine that the transect method is an inferior point selection method in terms of accuracy and efficiency.

Measures and Correlates of Daily Spiritual Experiences

Measures and Correlates of Daily Spiritual Experiences

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Mirbaha-Hashemi, Fariba
Description: Although a change of religious landscape in America in recent years has been suggested and widely accepted in the social sciences, most studies tend to focus on measures of religiosity and how it is changing. The subject of spirituality and its correlates seem to be mostly ignored. This study utilizes nationally representative data generated for the first time in General Social Survey (GSS) on the subject of spirituality to measure Americans' spirituality and daily spiritual experiences and their most significant correlates. In this study, most Americans (89%) showed to have some degree of spirituality and daily spiritual experiences. Moreover, variables of gender, race/ethnicity, marital status, religious origin, and residence in conservative region when growing up shown to be significant predictors of spirituality.

Comparison and Evaluation of Existing Analog Circuit Simulator using Sigma-Delta Modulator

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Ale, Anil Kumar
Description: In the world of VLSI (very large scale integration) technology, there are many different types of circuit simulators that are used to design and predict the circuit behavior before actual fabrication of the circuit. In this thesis, I compared and evaluated existing circuit simulators by considering standard benchmark circuits. The circuit simulators which I evaluated and explored are Ngspice, Tclspice, Winspice (open source) and Spectre® (commercial). I also tested standard benchmarks using these circuit simulators and compared their outputs. The simulators are evaluated using design metrics in order to quantify their performance and identify efficient circuit simulators. In addition, I designed a sigma-delta modulator and its individual components using the analog behavioral language Verilog-A. Initially, I performed simulations of individual components of the sigma-delta modulator and later of the whole system. Finally, CMOS (complementary metal-oxide semiconductor) transistor-level circuits were designed for the differential amplifier, operational amplifier and comparator of the modulator.

Stranger Than Fact

Stranger Than Fact

Date: December 2006
Creator: Saxton, Kelly E.
Description: As a dyslexic child, I always had trouble finding my voice. It's hard to express yourself in words, when you struggle with them. For me words always come later when I write. But most people don't understand how I feel. If your synapses fire off at the right time how can you image what it would be like it they didn't? That's where fiction comes in. If you can override someone's lack of experience with the use of a metaphor, then by distancing the reader from reality with an allegory, you can get to truth that's hard to capture any other way. You can also simply tell the truth in your writing with plain nonfiction. For me, fiction and nonfiction are a way for me to claim my voice and convey truth. Only a reader can decided what that truth looks like.
