Introduction. The coronavirus disease (COVID-19) in the past year and a half has become a worldwide pandemic. COVID-19 symptoms, severity and duration vary widely, with an increasing number of cases of unresolved and prolonged symptoms. Objectives. This study aims to characterize unresolved symptoms of mild COVID-19 patients for a period of five months after disease onset, and potentially aid in disease management. Methods. Seventy-five adult patients were involved in the study in the period October 2020- March 2021 in Eurofarm Centre Private Healthcare. Inclusion criteria required patients to be aged ≥18 years, with positive SARS-CoV2 PCR test results and non-severe symptoms which did not require hospitalization. The onset, duration and resolution of symptoms were analysed.

Purpose: The aim of this paper is to evaluate the perceived downward accountability and transparency of two public services – water supply and sewage and local road maintenance – in the Sarajevo Canton in Bosnia and Herzegovina (BiH).Design/Methodology/Approach: An opinion survey[1] on a sample of 250 respondents and four binomial regressions were conducted to measure the factors that affect the perceived downward accountability and transparency of the two public services.Findings: The results of binomial logit regressions indicate that in terms of perceived accountability and transparency of water supply and sewage, significant variables include gender, education, and satisfaction with the price the respondents pay for such service. Significant variables for perceived local road maintenance accountability include satisfaction with regular and winter local road maintenance, while for perceived transparency an additional significant variable is education.Academic contribution to the field: Although publications and literature dealing with the implementation of New Public Management in developed countries are plentiful, this is not the case in transition countries. The paper examines the case of the Sarajevo Canton and contributes to the research of perceived downward accountability and transparency. It may serve as a basis for further studies on public sector management in other local communities or small transition countries.Originality/Value: The paper contributes to the limited empirical literature regarding the perceived accountability and transparency and suggests ways to improve such.

Psychological pain is a social issue which is highly present in societies, and can accordingly have a significant negative effect on all aspects of a person's existence with particularly harmful consequences on chronic pain, thus increasing the possibility of developing comorbid psychiatric disorders. Clinicians often tend to label the appearance of psychological symptoms as a "normal" or usual response to physical ailments. Psychological pain or suffering is not only manifested on a psychological level, nonetheless, it is usually in a certain way immanent in the body itself. As regards the physical pain, there is an evident connection between awareness of the physical spot of pain in the body and the psychological experience of pain, which is not the case when it comes to emotional pain. The aim of this paper is to systematize and classify scientific findings and knowledge about psychological pain. The paper is based on the results of contemporary research in the field of psychology and other related sciences and scientific disciplines related to social and scientific issues. Psychological assessment of pain is of great importance due to the consequences it entails – including primarily the impaired physical and psychological integrity of a person, since the mind, reason, and emotions are mainly conditioned by the normal existence of the body. Psychological assessment of pain can have significant results in applied scientific research and modern social practice.

Posttraumatic stress disorder (PTSD) is triggered by extremely stressful environmental events and characterized by high emotional distress, re-experiencing of trauma, avoidance and hypervigilance. The present study uses polygenic risk scores (PRS) derived from the UK Biobank (UKBB) mega-cohort analysis as part of the PGC PTSD GWAS effort to determine the heritable basis of PTSD in the South Eastern Europe (SEE)-PTSD cohort. We further analyzed the relation between PRS and additional disease-related variables, such as number and intensity of life events, coping, sex and age at war on PTSD and CAPS as outcome variables. Association of PRS, number and intensity of life events, coping, sex and age on PTSD were calculated using logistic regression in a total of 321 subjects with current and remitted PTSD and 337 controls previously subjected to traumatic events but not having PTSD. In addition, PRS and other disease-related variables were tested for association with PTSD symptom severity, measured by the Clinician Administrated PTSD Scale (CAPS) by liner regression. To assess the relationship between the main outcomes PTSD diagnosis and symptom severity, each of the examined variables was adjusted for all other PTSD related variables. The categorical analysis showed significant polygenic risk in patients with remitted PTSD and the total sample, whereas no effects were found on symptom severity. Intensity of life events as well as the individual coping style were significantly associated with PTSD diagnosis in both current and remitted cases. The dimensional analyses showed as association of war-related frequency of trauma with symptom severity, whereas the intensity of trauma yielded significant results independently of trauma timing in current PTSD. The present PRS application in the SEE-PTSD cohort confirms modest but significant polygenic risk for PTSD diagnosis. Environmental factors, mainly the intensity of traumatic life events and negative coping strategies, yielded associations with PTSD both categorically and dimensionally with more significant p-values. This suggests that, at least in the present cohort of war-related trauma, the association of environmental factors and current individual coping strategies with PTSD psychopathology was stronger than the polygenic risk.

Introduction: Positive attitudes toward the nursing profession among nursing students improve the sustainability of the profession. Studying the attitudes of nursing students toward nursing is of great importance, as it can indicate their remaining in the profession. This study aimed to determine the attitudes of nursing students toward the nursing profession.Methods: This was a cross-sectional, descriptive, analytical study. The research was conducted at the Faculty of Health Studies at the University of Sarajevo from May to June 2019. The study involved a convenience sample of 107 currently enrolled Bachelor of Nursing students from the 1st to the 4th (and final) year of full-time study and part-time students in the Baccalaureate of Nursing Care program at the University of Sarajevo. The students voluntarily and anonymously completed a questionnaire consisting of demographic information and the Nursing Image Questionnaire.Results: Overall, 107 students participated in the research. Their mean age was 23 years old (standard deviation, 5 years). Spearman’s correlation factor shows a statistically significant correlation between the scores and the mode of studying (full-time or part-time) (rho = −0.200*, p = 0.039) and whether respondents working in the profession or not (rho = 0.249*, p = 0.010).Conclusion: The attitudes of future Bachelor of Nursing toward the nursing profession were very positive. Full-time students had more positive attitudes toward the profession, compared with part-time students, although the difference was not statistically significant.

Introduction: Perceptions of the esthetic appearance of teeth vary in different individuals and can affect satisfaction with the dental appearance, attitudes, and the need for appropriate dental treatment. The research aims to examine the factors influencing the satisfaction with the appearance of the dentition and the attitude toward treatments which improve dental esthetics among students of the faculty of dentistry in comparison to the attitudes of students of non-dental faculties.Methods: The research included a total of 358 students of the Faculty of Dentistry and Faculty of Architecture in Sarajevo who voluntarily filled out a questionnaire created for this research. The questionnaire contained questions related to satisfaction with the appearance of teeth in general, tooth color, tooth position, questions related to the previous, and future desired esthetic restorations and treatments.Results: Female subjects expressed statistically significantly greater dissatisfaction with the appearance of the dentition and did or plan to do treatments that could improve dental esthetics compared to male subjects. Students of the Faculty of Dentistry at final years were significantly more satisfied with the general appearance of teeth and tooth color compared to freshmen students of the Faculty of Dentistry and students of the Faculty of Architecture.Conclusion: Satisfaction with dental appearance is a subjective experience that is influenced by various factors, level, and type of education is among them.

In this work, we present a novel multi-modal multi-agent trajectory prediction architecture, focusing on map and interaction modeling using graph representation. For the purposes of map modeling, we capture rich topological structure into vector-based star graphs, which enable an agent to directly attend to relevant regions along polylines that are used to represent the map. We denote this architecture StarNet, and integrate it into a single-agent prediction setting. As the main result, we extend this architecture to joint scene-level prediction, which produces multiple agents’ predictions simultaneously. The key idea in joint-StarNet is integrating the awareness of one agent in its own reference frame with how it is perceived from the points of view of other agents. We achieve this via masked self-attention. Both proposed architectures are built on top of the action-space prediction framework introduced in our previous work, which ensures kinematically feasible trajectory predictions. We evaluate the methods on the interaction-rich inD and INTERACTION datasets, with both StarNet and joint-StarNet achieving improvements over state of the art.

: Students spend much time in doing their physics homework. Whether this effort results in deep learning depends on the quality of the mere homework. Therefore, we designed a minds-on simulation-based approach to physics homework and conducted a pretest-posttest quasi-experiment to compare its effectiveness to the effectiveness of traditional homework. Our student sample consisted of 39 first year high-school students from Bosnia and Herzegovina. In two school hours, all students received the same lectures about gas laws. Next, the experimental group students solved simulation-based homework in which their planning of actions, execution of actions and self-reflection was supported by a carefully prepared worksheet and survey. The traditional group’s homework consisted of three textbook problems and covered the same content, which is gas laws. Through analysis of covariance it was shown that the minds-on simulation-based homework was significantly more effective in developing students’ understanding of gas laws than traditional homework. The experimental group students perceived the simulation-based homework as interesting, challenging and useful.

This difference equation is one of the perturbations of the sigmoid Beverton–Holt difference equation, which is a major mathematical model in population dynamics. We will show that this difference equation exhibits transcritical and Neimark–Sacker bifurcations but not flip (period-doubling) bifurcation since this difference equation cannot have period-two solutions. Furthermore, we give the asymptotic approximation of the invariant manifolds, stable, unstable, and center manifolds of the equilibrium solutions. We give the necessary and sufficient conditions for global asymptotic stability of the zero equilibrium as well as sufficient conditions for global asymptotic stability of the positive equilibrium.</jats:p>

Many scholars perceive price competitiveness as a highly relevant element of tourism competitiveness in improving tourism performance. We focused our research interest specifically to understand whether price competitiveness is an important policy instrument in attracting international tourists and their spending. Our empirical study focused on how price competitiveness behaves as a predictor of tourism performance in different economic conditions and whether price competitiveness is a significant cause of tourism competitiveness in improving tourism performance. For that purpose, we conducted empirical analysis within two stages: moderation analysis to understand how price competitiveness influences tourism performance from the point of view of inbound international tourism and how this relationship behaves in different economic conditions; and mediation analysis to understand whether price competitiveness is relevant cause for tourist competitiveness in improving tourism performance. This study has revealed different views about price competitiveness and its influence on the tourism industry. The findings indicate that price competitiveness has rather limited effects on the outcomes of the tourism industry and is not a cause of overall tourism competitiveness in improving tourism performance.
