Abstract Purpose: The purpose of this article is to examine the relationship between employee participation in the decision-making process (EPDMP) and organizational citizenship behavior (OCB) while considering the mediating role of affective commitment (AC). Methods: The article is based on primary cross-sectional data collected using questionnaires and applying a convenience sampling method among employees in Bosnia and Herzegovina (B&H). The sample consists of 302 employees from 127 companies across multiple industries. Results: First, there is a positive relationship between EPDMP and two dimensions of OCB – organizational citizenship behavior directed at individuals (OCBI) and organizational citizenship behavior directed at the organization (OCBO). Second, the findings suggest that AC mediates the relationship between EPDMP and OCBI and OCBO. Furthermore, OCBI is found to mediate the relationship between AC and OCBO. Conclusion: This article extends the literature by introducing the mediating role of AC in the relationship between EPDM and two dimensions of OCB and the mediating role of OCBI in the relationship between AC and OCBO.

Aim To examine the prevalence of depression in patients after acute myocardial infarction (AMI), as well as the relationship between the depression and quality of life. Methods The survey was conducted via sociodemographic questionnaire, Beck Depression Inventory (BDI), and Short Form 36 Health Survey questionnaire (SF-36). The result of SF-36 is expressed in subscales that make up the health status profile, i.e. physical functioning, physical role, emotional role, social functioning, mental health, vitality, pain and general health. Results The study included 120 patients, of which 70 males and 50 females aged between 41 and 88 years (mean 64.73±11.218). All patients were hospitalized at the Clinical Centre of the University of Sarajevo, Clinic for Cardiovascular Disease and Rheumatism, due to complications caused by AMI. After AMI 59 (49.17%) patients had depression. Depression was negatively associated with physical functioning, physical role, emotional role, social functioning, mental health, vitality, pain and general health. Physical functioning (r= -0.701; p<0.01) and physical role (r = -0.538; p<0.01) had the highest correlation with depression. Conclusion The evaluation of depressive symptoms after AMI is imperative, because the appearance of symptoms could have an effect on the patient's quality of life.

Motivated by the recent paper [M.R.S. Kulenović, M. Nurkanović, and A.A. Yakubu, Asymptotic behaviour of a discrete-time density-dependent SI epidemic model with constant recruitment, J. Appl. Math. Comput. 67 (2021), pp. 733–753. DOI:10.1007/s12190-021-01503-2], in this paper, we consider the class of the SI epidemic models with recruitment where the Poisson function, a decreasing exponential function of the population of infectious individuals, is replaced by a general probability function that satisfies certain conditions. We compute the basic reproduction number We establish the global asymptotic stability of the disease-free equilibrium (GAS) for We use the Lyapunov function method developed in [P. van den Driessche and A.-A. Yakubu, Disease extinction versus persistence in discrete-time epidemic models, Bull. Math. Biol. 81 (2019), pp. 4412–4446], to demonstrate the GAS of the disease-free equilibrium and uniform persistence of the considered class of models. We show that the considered type of model is permanent for . For the transcritical bifurcation appears. For we prove the global attractivity result for endemic equilibrium and instability of the disease-free equilibrium. We apply theoretical results to specific escape functions of the susceptibles from infectious individuals. For each case, we compute the basic reproduction number .

Abstract Within the span of only four years, two books on the same subject and with almost identical titles were published on two sides of Europe: Hans Prinzhorn's Artistry of the Mentally Ill (Berlin, 1922) and Pavel Ivanovich Karpov's Creativity of the Mentally Ill (Moscow, 1926). Whereas the first book was recognized as one of the key steps in the “discovery” of the psychotic art and its eventual mainstreaming, the second one quickly fell into obscurity. Its author perished in Stalinist purges of the 1930s, together with a number of his colleagues from the Russian Academy of Artistic Science (RAKhN, 1921-1931), in which he served as the head of the Commission for the Creativity of Mentally Ill. This article is the first in-depth study of Karpov's book and his theory of creativity, which he based on his extensive collection of the works of his patients (which was also lost in the purges). The article argues that his approach to psychotic art is completely independent from Prinzhorn's. Instead, it places this book in the context of the specific form of Kunstwissenschaft that was practiced in RAKhN, suggesting that this placement is of primary importance for understanding Karpov's methods and aims. More specifically, the article argues that in his research on the creativity of the mentally ill, Karpov engages in a productive dialogue with the philosopher and prominent RAKhN member Gustav Shpet's work on epistemology from the same period. The result is an original contribution to the clinical literature on art of the mentally ill patients.

This study was to examine the response of biofertilizer formulation with the addition of consortium of microbes and biosurfactant DEA palm olein to the growth of cacao seedling. This research used randomized block design in factorial with two factors. The first factor was a biofertilizer formulation with addition of consortium of microbes consisting of seven levels: control; 2.5x107; 5x107; 7.5x107; 10x107; 12.5x107; and 15x107 CFU/mL. The second factor was the addition of biosurfactant DEA palm olein consisting of two levels, which are with and without the biosurfactant DEA palm olein. The result showed that the biofertilizer formulation with the addition of consortium of microbes was significantly affected the cacao height on 4 WAT (week after treatment), the leaf number on 6 and 12 WAT, and also in its root fresh weight parameters. The best level of the first factor was 5x107 CFU/mL. The respond of cacao height on 12 WAT and cacao root dry weight was significant to the addition of biosurfactant DEA palm olein. The best level of the second factor was with the addition of biosurfactant DEA palm olein.

Mechanical (hardness and adhesion) and electrical (sheet resistance) characteristics of electrolytically produced copper coatings have been investigated. Morphologies of Cu coatings produced galvanostatically at two current densities from the basic sulfate electrolyte and from an electrolyte containing levelling/brightening additives without and with application of ultrasound for the electrolyte stirring were characterized by SEM and AFM techniques. Mechanical characteristics were examined by Vickers microindentation using the Chen–Gao (C–G) composite hardness model, while electrical characteristics were examined by the four-point probe method. Application of ultrasound achieved benefits on both hardness and adhesion of the Cu coatings, thereby the use of both the larger current density and additive-free electrolyte improved these mechanical characteristics. The hardness of Cu coatings calculated according to the C–G model was in the 1.1844–1.2303 GPa range for fine-grained Cu coatings obtained from the sulfate electrolyte and in the 0.8572–1.1507 GPa range for smooth Cu coatings obtained from the electrolyte with additives. Analysis of the electrical characteristics of Cu coatings after an aging period of 4 years showed differences in the sheet resistance between the top and the bottom sides of the coating, which is attributed to the formation of a thin oxide layer on the coating surface area.

Electronic word of mouth is a more recent form of word of mouth used by internet users who share and benefit from worldwide information. Online reviews are a very important source of information for tourists. They represent a more modern and a more reliable source of information in decision making process when compared with the content published by the foreign travel agencies. Previous research has shown that the online reviews on websites specialized for hotel ratings made a significant impact on the total number of hotel reservations. The majority of tourists find online reviews very useful and more than half of them will not make a hotel reservation if a hotel has no reviews. Since the private accommodation is quantitatively the most significant accommodation type in Croatia, the goal of this paper is to analyze the impact of electronic word of mouth on the tourist selection of private accommodation for holidays.

Within the immune system, microRNAs (miRNAs) exert key regulatory functions. However, what are the mRNA targets regulated by miRNAs and how miRNAs are transcriptionally regulated themselves remain for the most part unknown. We found that in primary human memory T helper lymphocytes, miR-150 was the most abundantly expressed miRNA, and its expression decreased drastically upon activation, suggesting regulatory roles. Constitutive MIR150 gene expression required the RFX family of transcription factors, and its activation-induced down-regulation was linked to their reduced expression. By performing miRNA pull-down and sequencing experiments, we identified PDGFA-associated protein 1 (PDAP1) as one main target of miR-150 in human T lymphocytes. PDAP1 acted as an RNA-binding protein (RBP), and its CRISPR/Cas-9–mediated deletion revealed that it prominently contributed to the regulation of T-cell proliferation. Overall, using an integrated approach involving quantitative analysis, unbiased genomics, and genome editing, we identified RFX factors, miR-150, and the PDAP1 RBP as the components of a regulatory axis that restrains proliferation of primary human T lymphocytes.

Increasing drivers (i.e. pressures) on nature are present at the global scale, resulting in the upgrowth of the number of endangered species and habitats, as well as a decrease in the capacity of ecosystems to provide various benefits to the human population. Recent studies indicate that natural ecosystems are frequently unable to adequately and efficiently provide the flow of ecosystem services or nature’s contribution to people (i.e. NCP), emphasising that this negative trend will continue in the future. These trends can be linked with the existence of drivers or pressures on nature, which are numerous and have an increasing trend over time. Pressures on nature are all changes and disturbances in the functioning of biological processes and systems, followed by disruption of the ecosystem structure and the integration of the living world. In order to prevent the loss of biodiversity and ensure NCP, it is important to recognize and understand direct and indirect pressures on nature. In this sense, this paper presents the spatial distribution, intensity, trends and drivers of individual categories of pressures on nature in Bosnia and Herzegovina, as well as their combined effect. The presentation of pressures on nature is based on 16 broadly recognizable groups of ecosystems that include broad natural units (e.g. high mountain complexes), or a complex of ecological factors (e.g. dry and rocky meadows and pastures), the dominant type of use (e.g. agricultural areas) or the dominant type of pressures (e.g. urban areas) (Figures 2 and 3, Table 1). For the purposes of assessing the intensity of certain categories of pressures (direct and indirect) and their trends per ecosystem groups, an expert assessment procedure was carried out, using a structured research instrument, that enabled the analysis of experts’ views when it comes to the intensity and trend of certain categories of pressures for each ecosystem group (Tables 2 and 3). The results of this research indicate that the urban ecosystems, running water ecosystems and agricultural ecosystems are under the highest pressure, while the lowest pressures are associated with the underground and canyon ecosystems (Figures 4–13, 16). Direct pressures are generally rated as more intense than indirect pressures (Figures 14 and 15). For the majority of analysed direct and indirect pressures, similar effects and trends are confirmed as at the global level. According to the opinion of the experts, who participated in this research, overuse and pollution were assessed as the highest direct pressures on nature in Bosnia and Herzegovina, while institutional pressure was recognised as the highest indirect pressure. Keeping in mind that, according to their characteristics, institutional pressures are inseparable from the state authority and its institutions while, in the context of Bosnia and Herzegovina, they are inevitably linked to the socio-political organization and numerous criticisms of the (non)functioning of institutions. Groups of ecosystems with a significant share in total area (e.g. arable land, lowland and mountain deciduous forests and shrubs, etc.) are also characterized by high pressure with a moderate or increasing trend. Although competent institutions in Bosnia and Herzegovina participated in various international processes, systemic and institutional activities that would result in the application of good practices of the international initiatives regarding nature protection and sustainable use of natural resources are often missing. In that sense, the results of this research provide the decision-makers and the scientific community with scientifically based arguments and overall directions for the decision-making process and conducting future research in the field of natural resources and their sustainable use.
