1. Deep learning criminal networksHaroldo V. Ribeiro, Diego D. Lopes, Arthur A. B. Pessa, Alvaro F. Martins, Bruno R. da Cunha, Sebastián Gonçalves, Ervin K. Lenzi, Quentin S. Hanley, Matjaž Perc, 2023, izvirni znanstveni članek Opis: Recent advances in deep learning methods have enabled researchers to develop and apply algorithms for the analysis and modeling of complex networks. These advances have sparked a surge of interest at the interface between network science and machine learning. Despite this, the use of machine learning methods to investigate criminal networks remains surprisingly scarce. Here, we explore the potential of graph convolutional networks to learn patterns among networked criminals and to predict various properties of criminal networks. Using empirical data from political corruption, criminal police intelligence, and criminal financial networks, we develop a series of deep learning models based on the GraphSAGE framework that are able to recover missing criminal partnerships, distinguish among types of associations, predict the amount of money exchanged among criminal agents, and even anticipate partnerships and recidivism of criminals during the growth dynamics of corruption networks, all with impressive accuracy. Our deep learning models significantly outperform previous shallow learning approaches and produce high-quality embeddings for node and edge properties. Moreover, these models inherit all the advantages of the GraphSAGE framework, including the generalization to unseen nodes and scaling up to large graph structures.

2. The witness protection program in Bosnia and Herzegovina in cases of organised crimeAdnan Jusufspahić, 2013, izvirni znanstveni članek Opis: Purpose:
This article presents the Witness Protection Program in BiH and the conditions for meeting the requirements for the starting the Witness Protection Program. It summarizes and explains the institution of the Witness Protection Program – the model in BiH, and considers the new proposals for de lege ferenda solutions within the Law on Witness Protection Program in BiH. Design/Methods/Approach:
In this study, the author used scientific methods, such as analysis, comparative methods, and case studies, as well as quantitative and qualitative research. The data used in this study is based on the survey that shows the size of groups of offenders accused for organized crime in BiH in the 2004–2008 period. The study covers criminal organizations that were founded in BiH at the beginning of 2003, and sentenced for organised crime.
Findings:
The aim is to present the active role of the Witness Protection Program as a relevant mechanism for fighting organized crime today. The study also deals with the importance of international relocation and identity change of witnesses, the situation and role of the protected witness.
Originality/Value:
The Witness Protection Program is a new institution in the field of criminal justice in BiH, but it is not the only one, and it should be the primary tool for the joint fight against organized crime in Bosnia and Herzegovina. The study also reflects on the model in BiH as an important factor in the international surrounding, its active role, its participation and contribution in the protection of future protected witnesses and their unobstructed testimonies in criminal proceedings.

3. The impact of corruption and organized crime on the development of sustainable tourismJanez Mekinc, Tina Kociper, Bojan Dobovšek, 2013, izvirni znanstveni članek Opis: Purpose:
This study focuses on the phenomenon of organized criminality and corruption. Its purpose is to analyse and explain how organized crime and corruption impact the processes of environmentally sustainable development and, indirectly, the development of tourist destinations and activities.
Design/Methods/Approach:
We analyzed relationships between tourist destinations, sustainable tourism, organized crime, and corruption from secondary data. We further synthesize findings and supplement them with observations and previous research findings.
Findings:
Organized crime and corruption have a direct impact on the sustainable development of tourist destinations and also on the services and activities of sustainable tourism. Based on a comparison of several indexes, the sustainable development of tourist destinations is greatly (negatively) affected by ecocriminality which holds back the development of sustainable tourism. It can be concluded that countries with less corruption have a better developmental sustainability, which is the building block of sustainable tourism.
Originality/Value:
Developing theoretical explanations and systematic studies are necessary as a first order of business if countries wish to prosecute organized crime and corruption relating to tourism. This is the first study in Slovenia dealing with this problem, thereby opening many questions for future research.
