AbstractAll highly centralised enterprises run by criminals do share similar traits, which, if recognised, can help in the criminal investigative process. While conducting a complex confederacy investigation, law enforcement agents should not only identify the key participants but also be able to grasp the nature of the inter-connections between the criminals to understand and determine the modus operandi of an illicit operation. We studied community detection in criminal networks using the graph theory and formally introduced an algorithm that opens a new perspective of community detection compared to the traditional methods used to model the relations between objects. Community structure, generally described as densely connected nodes and similar patterns of links is an important property of complex networks. Our method differs from the traditional method by allowing law enforcement agencies to be able to compare the detected communities and thereby be able to assume a different viewpoint of the criminal network, as presented in the paper we have compared our algorithm to the well-known Girvan-Newman. We consider this method as an alternative or an addition to the traditional community detection methods mentioned earlier, as the proposed algorithm allows, and will assists in, the detection of different patterns and structures of the same community for enforcement agencies and researches. This methodology on community detection has not been extensively researched. Hence, we have identified it as a research gap in this domain and decided to develop a new method of criminal community detection.

The many cases of Illegal Fishing, threaten the wealth of fisheries and sovereignty of Indonesia. This study aims to explain the urgency of the Follow the Money approach in handling fisheries crime cases by PPNS Fisheries. Then provide concrete recommendations for the Follow the Money implementation in handling fisheries crime cases. This paper is a  normative  juridical study,  which  is  processed qualitatively. The results of this study indicate the urgency of the Follow the Money approach in handling fisheries crime cases by PPNS Fisheries due to Indonesia's large fishery wealth; the magnitude of the threat of illegal fishing in Indonesia; lack of fisheries crime cases handled by PPNS Fisheries; and the development of the modus operandi of fisheries criminals. Then, the efforts made in the Follow the Money approach are by increasing collaboration with PPATK institutions; increased cooperation with international law enforcement agencies; and the use of electronic transaction evidence as evidence at court.

Abstract Human Trafficking (HT) is considered as one of the most complex crimes to investigate. However, to date, little research has been conducted concerning what occurs during criminal investigations of HT. The present study, through interviewing 21 highly experienced and senior professionals from law enforcement agencies and governmental bodies in the UK, conceptualizes HT investigations under a common framework that underpins a model for the investigation of these crimes. Data from these narratives reveals that a total number of 22 investigative actions are commonly taken throughout the investigative process, following an apparent sequential route. While participants disagreed as to when/how to initiate and conclude an investigation, absolute agreement existed when considering multi-agency collaboration, tactical advice and support, and intelligence sharing (as core elements in HT criminal investigations). Such data enables both academic and practitioner communities to better identify what are effective investigation actions when these crimes are investigated.

Abstract BackgroundDiscovering functional modules in protein-protein interaction networks through optimization remains a longstanding challenge in Biology. Traditional algorithms simply consider strong protein complexes found in the original network by optimizing some metric, which may cause obstacles for discovering weak and hidden complexes that are overshadowed by strong complexes. Additionally, protein complexes have not only different densities but also various ranges of scales, making them extremely difficult to be detected. We address these issues and propose a hierarchical hidden community detection approach to predict protein complexes of various strengths and scales accurately. ResultsWe propose a meta-method called HirHide (Hierarchical Hidden Community Detection). It is the first combination of hierarchical structure with hidden structure, which provides a new perspective for finding protein complexes of various strengths and scales. We compare the performance of several standard community detection methods with their HirHide versions. Experimental results show that the HirHide versions achieve better performance and sometimes even significantly outperform the baselines. ConclusionsHirHide can adopt any standard community detection method as the base algorithm and enable it to discover hidden hierarchical communities as well as boosting the detection of strong hierarchical communities. Some biological networks are too complex for standard community detection algorithms to produce a positive performance. Most of the time, a better choice is to choose a corresponding algorithm based on the characteristics of a specific biological network. Under these circumstances, HirHide has clear advantages because of its flexibility. At the same time, according to the natural hierarchy of cells, organelle, intracellular compound etc., hierarchical structure with hidden structure is in line with the characteristics of the data itself, thus helping researchers to study biological interactions more deeply.

A central feature of new law enforcement agencies, established specifically to combat organised crime in Australia, is their use of internal multi-disciplinary investigation teams. This strategy can be seen as mirroring the structure and modus operandi of the targeted criminal activity. One of the first law enforcement agencies in Australia to 'collectivise' legal and policing skills has been the National Crime Authority. However, aspects of the legal and police 'sub-cultures' are structurally and ideologically inconsistent creating the potential for significant intra-organisational conflict. This article explores the nature and significance of 'cultural clashes' between lawyers and police within the National Crime Authority, and describes a number of unique legal problems arising from the cross-jurisdictional deployment of police officers on secondment to the National Crime Authority. The article argues that in the context of organised crime, sub-cultural dimensions of law enforcement has been a neglected area within criminological research and policy making. The article argues that organisational sub-cultures have limited the capacity of law enforcement agencies to fulfil their junctions and suggests a number of reforms.

Substantial research has examined both the barriers preventing women from entering and flourishing in policing and the coping mechanisms used to adapt to the gendered institution of policing. However, there is scant research that examines the mechanisms by which some women successfully navigate the police bureaucracy. Drawing from in-depth, semi-structured interviews of 47 female officers from 30 law enforcement agencies across seven states, we apply Constrained Agency Theory as a means to identify and understand how women capitalize on conditions and opportunities to advance and/or gain promotion in gendered organizations. The purpose of our research is to explore the efficacy of this theoretical framework for the study of women in policing. Results suggest that Constrained Agency Theory offers a promising way of understanding how female officers experience and utilize opportunities and conditions for advancement across a variety of agencies, generations, and organizational cultures.

Cash waqf in Indonesia has been long enough implemented based on some rules enacted by government and other rules defined by The Waqf Board of Indonesia (BWI). However, the implementation of cash waqf has not reached the level of success. Therefore, this article studies the application of cash waqf law in Indonesia according to Friedman’s legal system theory. The legal system theory of Friedman firstly looks at the substance of the law, which is the rules or regulations; and secondly it examines the structure of the law, encompassing the law enforcement agencies, such as judge, prosecutor, police and legal counselors. And lastly the theory examines the element of legal culture, which is a response from Muslim society. The first two examinations indicate that there is nothing to be a problem. But from the last examination there is a problem regarding the trust from Muslim society. From the legal culture point of view, the implementation of cash waqf by the government, which is performed by BWI, needs attracting society’s credentials in order to improve and maximize the performance of cash waqf in Indonesia.

Abortion is a social phenomenon that is increasingly alarming. The concern is not without reason, because so far the behavior of abortion many negative effects both for themselves the perpetrators and the wider community. With the passing of the Government Regulation No. 61 Year 2014 on Reproductive Health still raises the pros and cons in the middle of the community. The approach used to address the problem that the above problems are normative juridical approach. Based on the results of the study need to decriminalize abortion in Government Regulation No. 61 Year 2014 on Reproductive Health which has the goal of creating the legal basis for abortion and the experts who helped him as an indication of a medical emergency or pregnancy due to rape, and factors inhibiting the decriminalization of abortion is legal factors themselves, law enforcement officials factors, factors facilities or infrastructure, community factors, and cultural factors. Suggestion that the author should the government needs to review the Government Regulation No. 61 Year 2014 on Reproductive Health in particular Article 31 and Article 34 within the limited evidence of rape victims in just 40 days because of the time limit is not relative to the law enforcement agencies to prove it, as well as regarding the evidentiary aspects of pregnancy due to rape victims in order to avoid an impression of legitimizing the act of abortion in any form.
