Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This dissertation aims to develop a mathematical model for determining violent crime rates, focusing on the relationship between property crime, policing enforcement, and violent crime occurrences. The model is tested using data from various cities globally.

• The relationship between property crime and violent crime.
• The impact of policing enforcement on crime rates.
• The application of a mathematical model to predict violent crime.
• Cross-city comparisons of crime patterns.
• Testing the Broken Windows Theory in a global context.

Zusammenfassung der Kapitel (Chapter Summaries)

Chapter 1: Introduction: This chapter introduces the research problem of determining violent crime rates and its significance. It provides a brief overview of the study's methodology and expected contributions to the field of crime analysis. The introduction sets the stage for subsequent chapters by outlining the problem of high violent crime rates in global cities and the need for better predictive models. It highlights the central research question: Can a model be developed that successfully predicts violent crime rates based on property crime and policing?

Chapter 2: Literature Review: This chapter reviews existing literature on violent crime, property crime, and the relationship between them. It examines existing theories, such as the Broken Windows Theory, and discusses previous studies that have investigated the correlation between property crime and violent crime. This review establishes the theoretical foundation for the mathematical model proposed in later chapters, synthesizing the existing research and highlighting gaps in knowledge. It explains which aspects of previous research are relevant to the current study and what innovations are needed.

Chapter 3: Methodology: This chapter details the research methodology employed, including the data sources, statistical techniques, and the development of the mathematical model. It explains the selection of case study cities and the rationale behind using a multiple regression analysis and Spearman rank correlation. The methodology section establishes the rigor and transparency of the research design, ensuring replicability and validation of the results. The chapter explains in detail how the data was gathered, processed, and analyzed to ensure consistency and accuracy.

Chapter 4: Case Study: São Paulo: This chapter presents a detailed case study of São Paulo, Brazil, utilizing a monthly crime dataset from the Department of Public Safety for the years 2011-2014. A multiple regression analysis is performed to examine the relationships between variables and test the validity of the proposed mathematical model. The São Paulo case study serves as a primary example for illustrating the applicability and robustness of the model developed. The chapter discusses the specific findings for São Paulo and their implications for understanding the dynamics of crime in that city.

Chapter 5: Case Studies: Other Cities: This chapter expands the analysis to nine of the world's most violent cities in 2013, using data to estimate Spearman rank correlation and price elasticities for various crimes. This allows for a broader validation of the mathematical model and a comparison of crime dynamics across diverse contexts. The chapter analyzes the results for these cities and compares them with the findings from the São Paulo case study. It assesses the extent to which the model's predictions are consistent across different cities and explores potential reasons for any observed discrepancies.
