This chapter examines World War II and its impact on international and military law. It covers the war’s key crimes, the Nürnberg and Tokyo tribunals, and the creation of the United Nations, the Four Geneva Conventions of 1949, and the Genocide Convention of 1948.

Empirical literature is the primary source of understanding how policing can effectively reduce criminal activities. Spatial analyses can identify particular effects that can explain and assist in constructing appropriate regional strategies and policies; nevertheless, studies that use spatial regression methods are more limited and can provide a perspective on specific effects in a more disaggregated regional context.

This research aims to conduct a systematic literature review (SLR) to understand the relationship between crime indicators and police production using spatial regression models. We consider a combination of Kitchenham and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocols as a methodological strategy in five bibliographic databases for collecting scientific articles.

The SLR suggests a limited amount of evidence that meets the criteria defined in the research strategy. Several particularities are observed regarding police and criminal production metrics, either in terms of aggregation level, indicator transformations or scope of analysis. A broader time perspective did not necessarily indicate statistical significance compared to models with a single-period sample.

The findings suggest the possibility of expanding efforts by the public sector to provide policing data with the intention of conducting appropriate research using spatial analysis. This step could allow for a more robust integration between the public sector and researchers, strengthening policing strategies, evaluating the effectiveness of public security policies and assisting in the development of strategies for future policy actions.

Limited empirical evidence meets the criteria of spatial regression models with temporal components considering police production and criminality indicators. Constructing an SLR with this scope is an unprecedented contribution to the literature. The discussion can enhance the understanding of approaches for studying the relationship between police efforts and crime prevention.

The paper aims to investigate the effect of GDP growth on crime and to test the hypothesis of nonlinearity. Additionally, we estimate the interaction between GDP and income inequality and examine its impact on the relationship between GDP and homicide rates.

The study utilizes panel data from the Organization for Economic Cooperation and Development (OECD), spanning the period from 2000 to 2018 and estimates dynamic panel GMM models.

We found a nonlinear relationship between GDP and homicide rates, indicating a dual effect of GDP on the occurrence of lethal crimes. Moreover, income inequality conditions the effect of GDP on homicide rates, exerting a significant influence. We conclude that in contexts characterized by high levels of income inequality, GDP growth is more effective in reducing crime, as there is greater potential for improvement.

This paper contributes to the existing literature by providing insights into the complex nonlinearity between economic conditions, income inequality and homicide rates.

This section begins with the story of Raul, a young homeless man who dwells in the streets of Buenos Aires city. Raul is 25 years old and has four children who live with his former wife. Divorced because of a problem with drinking, he sleeps here, there, and everywhere but prefers bus stations or tourist destinations. In this way, he not only feels safer but also lives on the charity of foreign tourists. Hotels or bus stations offer safe shelter in case of rain or the ruthless winter. Because of the currency exchange gap between pesos and dollars, tourist destinations are targeted by many homeless men in Buenos Aires City. Having said this, he works as “reciclador urbano – urban recycling” a new nomenclature associated with persons who sort trash to collect recyclables. Known as cartoneros (litter-pickers) as well, these persons started to become a part of Buenos Aires city. At first glimpse, many cartoneros never come back to their homes, located in Provincia de Buenos Aires they sleep and live roaming Buenos Aires traversing from one to another point of the city. The opposite is equally true, like Raul, Buenos Aires airport has turned into an unofficial homeless shelter receiving more than 50 persons each night.

This chapter explores the nature of military law and IHL during the cold war period. It explores what treaties were completed, Additional Protocols I and II of the 1949 Geneva Conventions, the ad hoc international tribunals of the 1990s and 2000s, and examines the ICJ’s ruling of the legality of nuclear weapons.

This chapter discusses the creation, structure, and functioning of the International Criminal Court. It also examines its operations to date and addresses many contemporary criticisms of the court.
