The use of technologies in achieving real-time situational awarenessduring police intervention
Get PDFDecision-making and discretion in police interventions should be based on relevant and objective information. Complexity, level of risk, unpredictability, and uncertainty are some of the features of police interventions in which police officers need to decide how to act in a few seconds. In limited timeframe, the police officer should find and select all available information relevant to make the decision. Decision-making gets complicated and more challenging in po-lice interventions where there is a risk of police officers getting injured and where they need to use force. The psychological pressure such situations create can negatively affect officers’ situa-tion awareness or their ability to observe and choose among pieces of information essential for decision-making. Consequently, relevant information may not reach the police managers who are expected to react to every change in the situation with an adequate decision. The problem of loss or lack of situational awareness in complex and risky police interventions has long been noticed. In order to maintain situational awareness during interventions and timely get the necessary information, body-worn cameras, unmanned aerial vehicles (UAVs) for live coverage of events from the police intervention scene and geographic information systems (GIS) to integrate data from the field could be used. These technologies allow managers in police headquarters to follow all events during the police intervention “live”, to be familiar with the deployment and status of engaged resources at all times, notice problems, and accordingly make decisions even before receiving (or in case of delay) information via the radio communication system. Having in mind the importance of situational awareness in complex and risky inter-ventions for decision-making, the paper points to the possibilities of using body-worn cameras, UAVs, and GIS to ensure situational awareness during interventions
Physical activity level of Police University students according to IPAQ: A pilot study
Get PDFThe aims of research were to determine the Police University students’ level of physical activity as well as to determine the differences in relation to gender. The total sample consisted of 60 subjects (30 male and 30 female). For assessing the levels of physical activity International Physical Activity Questionnaire (IPAQ) was used. Based on IPAQ scores (MET), the level of physical activity is classified as high, moderate and low. Results of descriptive statistics showed that the average value for a male student was 8157.63 ± 3365.00 MET, while for a female one it was 3793.57 ± 3152.80 MET. ANOVA results showed that there is a statistically significant difference between genders at the general level (F = 26.870, p = 0.000), as well as at the partial level for high (F = 21.229, p = 0.000) and moderate (F = 31.898, p = 0.000) level of physical activity in favor of males
The influence of the various specialized physical education teaching programs on students’ aerobic endurance
Get PDFAerobic endurance (AE) is considered as one of the physical abilities that determines success on job-related physical tests for police officers. Therefore, AE is one of the criteria in selection process, during the education and through working career. At the University of Criminal Investigation and Police Studies (UCIPS) the development of the level of AE takes place within the course of Specialized Physical Education (SPE). In the school year 2020/2021, due to the COVID-19 pandemic measures, SPE classes were organized in two models: regular (the firstyear students) and online (the second, third- and fourth-year students). The aim of this study
was to determine the influence of these different modules of SPE studying on AE of the UCIPS students. The sample of the respondents included 46 students of the first year (19 women and 27 men) and 45 students of the third year (21 women and 24 men). AE was estimated by using Cooper’s running test at the start and at the end of the observed studying year. The difference between initial and final testing was defined by using a pair sample t-test. It was determined that AE increased by 5.5% (t = -3.353, p = 0.004) with women and for 4% (t = -3.139, p = 0.004) with men for the first-year students. In contrast, the third-year students had the reduction of AE by
3.6% (t = 2.415, p = 0.025) with women and by 6.2% (t = 3.354, p = 0.003) with men
The Duty to Protect the Right to Life
Get PDFThe author analyses one aspect of the right to life - the duty to protect the right to life. That aspect is not encompassed in definitions of the right to life in clear and explicit words. However, it is elucidated through the process of interpretation by various bodies, both international and national. Explicit inclusion of this element is thoroughly analysed in General Comment No. 36 adopted by the UN Human Rights Committee and it presents the starting point for the analyses in this paper. The duty to protect the right to life has also been elaborated in specific cases before the UN Human Rights Committee, the European Court of Human Rights and constitutional courts. Several of these cases have also been analysed within this paper. The aim of the paper is to identify the scope and limits of the duty to protect the right to life
The Influence of the Period of Retention on the Reliability of Episodic Memory in the Context of Testimony
Get PDFThe paper presents a study that aimed to examine the reliability of episodic memory by varying the retention time from the moment of initial observation of two incidents to the moment of communicating what was actually remembered. Ninety (90) students aged 21-26 from the University of Criminal Investigation and Police Studies participated in the research (50 males and 40 females). The interval of retention presented an independent variable on four levels: immediately after watching a recording, after 1 month, after 3 months and after 6 months. The accuracy of recall, or remembering one aspect of the incident (characteristics of the event, characteristics of the perpetrators and characteristics of the victim) was a dependent variable. Results suggest that memory accuracy declines dramatically after a month, but also after three and six months, when the downward trend in memory accuracy is less pronounced. Regarding the degree of confidence in memory accuracy, the pattern of results is practically identical to that of memory accuracy. As a whole, the results indicate that the retention interval strongly affects both accuracy and certainty in memory accuracy, regardless of the type of crime and the characteristics being evaluated
Artificial intelligence and the challenge of rethinking legislation
Get PDFThe study examines the impacts of artificial intelligence on human rights, with a spe-cial focus on the challenge of how the use of AI can remain transparent, reliable and safe, while the advantages offered by it are retained. The aim of the authors is to shed light on the regulation paradox resulting from the black box effect arising in connection with AI. They lay a special emphasis on the fact that the adequate legal responses to an unknown technology depend on the risks identified through scientific research (“precaution principle”), though the interpretation of these risks may require a new system of aspects.In this context, the authors touch upon the risk-based approach proposed in the EU Committee’s White Book and the importance of the resulting preliminary authorisation and of continuous human control. At the same time, based upon the black box effect, which is a regulation paradox, the following dilemma is raised: Is it human or robot law that should be constituted?In connection with the efforts made to regulate the working of artificial general intelligence (AGI), i.e. the AGI safety concept, the study em-phasises that it is important to work out the principles and rules which will make the use of AGI safe already before the evolution/creation of AGI. Once AGI is there, logically, it will no longer be possible to do this as AGI may become independent and may act by its own. The authors also briefly touch upon the question of what AGIs can and cannot do (a question which raises many other issues). Further questions include whether AGIs should be controlled through penalising and restrictions or rewarding and motivation. Consequently, it is necessary to consider what AGIs’ actual rewards should be – which raises the need to redefine regulation and, in general, the regulatory system
