The importance and effectiveness assessment of internal control in the Slovenian policeBranko Lobnikar
, Kiara Ropoša
, 2020, original scientific article
Abstract: Purpose: The paper presents the findings of a study conducted on a sample of internal control providers within the Slovenian police as part of the target research project "Effectiveness of Systemic Control of the Police in Regard to Human Rights as well as the Statutory and Professional Standards of Police Work (V5-1942)". The purpose of the study was to analyse the control activity in the Slovenian police from the viewpoint of those carrying out control procedures. We were interested in their view of the control process and, through the interviews, we analysed the opportunities and shortcomings of the control activity within the Slovenian police in relation to systemic control conducted by external stakeholders. Design/Methods/Approach: We examined the regulatory framework of control activities in the public sector and in the police and presented the approaches used across Europe. In the empirical part, we conducted structured interviews with employees at the state level, namely with the employees tasked with carrying out control procedures in the General Police Directorate, the Criminal Police Directorate and the Uniformed Police Directorate, and we also conducted interviews with two superintendents at the Police Directorate level. We conducted a total of seven interviews. Findings: The research found that audits, whether carried out by the Ministry of the Interior or by the Police auditors, are seen as a vital element of the management of a police organization. The interview subjects emphasized the role of the heads of police units - both from the point of view of planning internal control activities and translating the findings of the audits into police practice. The dissemination of audit findings can be ensured through the digitization of police work processes; interviewees expressed the need for a systematic solution that would allow them to test the competencies of police officers. Research Limitations/Implications: The article presents the findings from the point of view of the employees responsible for carrying out control activities within the Slovenian police. For a more complete overview of the matter, our findings should be compared with the perspective of those who are the subjects of the control activities, i.e. the police officers who have undergone the control process. The findings of the research are useful primarily for the purposes of planning the processes related to the management and administration of police work and from the point of view of improving the quality of police work. Originality/Value: The paper examines how the employees responsible for carrying out the control activities perceive their own work and how the processes involved in the control of police work are organized, how they function and how effective they are.

, 2011, original scientific article
The main subject of this paper is the analysis of attitudes of police officers (detectives) in Belgrade Criminal Investigation Department (CID) about the core principles of democratic policing – protecting the citizens, commitment to the law, legal constraints of police activities and their impact on the effectiveness of policing, control of police and their legal liability. We also analyzed their views on legal solutions regulating the application of those police powers which are of greatest importance for the protection of human rights and freedoms of citizens.
The work is based on empirical research conducted in the period from September to October 2009 which included 250 (a 25 % sample) police officers in the Belgrade Police Depatment. The questionnaire comprised 49 question, the first six of which pertaining to demographic data. Most questions were of the closed form.
The results of the research show that Belgrade police highly value objectives that are in the function of protecting interests of citizens, cooperation with citizens and absence of all forms of discrimination. They have shown animosity towards the law, as they perceive the law as a factor that limits thier efficiency. Efficiency of the police work is higly valued even at the cost of potentially violating human rights during the investigation. They consider the control of police work neccessary, preceiving the forms of internal control more useful than external control, especially those exerted by courts.
This is an exploratory research, its results show tendencies and broad generalizations are not possible.
Research results can be useful for police managers and for trainers in adjusting performance and attitudes of police officers in Belgrade PD.
The paper presents the findings of research upon which conclusions have been drawn regarding the perception of subjects regarding the most important issues arising from the democratic reform of police in Serbia.

Self-control and morality in Slovenian primary and secondary school sampleEva Bertok
, Gorazd Meško
, 2013, original scientific article
The purpose of this paper is to test one of the main concepts of Situational Action Theory – the concept of the crime propensity on a large Slovenian sample of young people ages 13–17. Crime propensity is constructed from self-control scale and moral values scale.
The factor analysis was used to see if separate dimensions of self-control could be distinguished. A multiple regression was run to predict 16 self-reported delinquent acts from morality and self-control variables, which represented generalized crime propensity index.
On the basis of 19 questions concerning self-control and moral values, almost one third of variance of self-reporting of 16 different delinquent acts was explained. The construct of crime propensity was proven relevant even with different methodology.
Research Limitations / Implications:
Even though YouPrev study employed a similar set of questions concerning self-control and moral values, some very cruicial differences should be noted between the two studies; the most important is the inclusion of risk-taking component in the self-control scale in the YouPrev study which was not included in the PADS+ study.
The paper presents the analysis that hasn’t been made yet in connection with self-reported delinquency acts in Slovenia.

Standard of control under Article 8 ARSIWALeon Brulc
, 2019, master's thesis
Abstract: State responsibility is considered an essential part of international law, since the whole body of international law would in essence be deemed ineffective if the States were not held liable for their conduct. States are the principal bearers of international obligations because of their legal personality. As a consequence, the fact that States have certain obligations, means that responsibility is heavily interlinked with the notion of sovereignty and vice versa. Similarly to individuals, sovereignty of States is limited with the rights of other States. However, this does not mean that State responsibility is an abandonment of State’s sovereignty, but rather its attribute.
A State cannot act on its own. It can only conduct its operations through its organs and through private actors. While the conduct of an organ of a State might automatically be attributed to that State, the attributability of a private actor’s conduct appears to be more problematic. One of the grounds of attribution of a private actor’s conduct is found in Article 8 of the International Law Commission’s Articles on Responsibility of States for Internationally Wrongful Acts (ARSIWA). Under Article 8 of the ARSIWA, private actor’s conduct is attributable to a State if that State instructs a private actor or if it controls or directs it. When it comes to the attribution on the grounds of control, the case law and theory, as to the degree of control required to trigger State responsibility, are at odds. While part of the theory defends the test adopted by the International Court of Justice (the effective control test), other academics defend the test proposed by International Criminal Tribunal for the former Yugoslavia (the overall control test). This clash is the focal point of the thesis.
While both of these tests were developed in a (para)military context, the question arises whether they can be applied to private corporations, and if the answer is yes, to what extent. In addition to proposing an appropriate test for corporations, this thesis also tries to find the appropriate test for (para)military group and determine whether there should be only one test for attribution or if there ought to be multiple.
