Published: June 2024

Bereavement following an opioid overdose death (OOD) is a particularly disturbing circumstance of sudden, unexpected loss. Despite epidemic proportions, little is known about grief in the wake of an OOD. We surveyed N=158 individuals grieving an OOD, supporting someone actively using opioids, or grieving while supporting similar others, to better understand the mental health impacts of these experiences. Study participants completed assessments of depression, anxiety, posttraumatic stress disorder (PTSD), substance use disorder (SUD), and prolonged grief disorder (PGD). Regression models examined associations between learning of a loved one’s opioid use, the OOD of a child, the OOD of a contemporary, increases in substance use following the event, and current mental health symptoms. Post-hoc path modeling evaluated mediated relationships between losing a child or contemporary to OOD and current mental health symptoms. Losing a child to OOD was associated with increased overall substance use (OR=4.10) during the following year and increased current symptoms of PGD (=0.46). Increasing substance use following the event was significantly associated with greater current symptoms of PGD (=0.24), PTSD (=0.28), SUD (=0.29), and depression (=0.27). Indirect effects mediated by increased substance use after the event were observed between both types of bereavement and current symptoms of depression, PTSD, and SUD. Substance use post-loss appears to contribute to adverse outcomes and future research should address ways to reduce substance use and promote adaptive coping in OOD bereavement.
Expressive Writing as a practice against Work Stress: A randomized controlled trial with preselection
Authors: Lukenda Kimberly , Sülzenbrück Sandra , Sutter Christine
Published: June 2024

This study investigates the impact of expressive writing on work stress, employing a 2 x 3 x 2 factorial design. Participants, pre-selected for high stress levels, were randomly assigned to either an experimental or control group and assessed at three different time points, with sex considered as the third factor. The aim was to evaluate the effects of expressive writing on work stress, work engagement, job demands, job resources, and personal resources, and to determine if the Job Demand-Resource (JD-R) model effectively explains the influence of expressive writing on work stress. Contrary to expectations, expressive writing did not reduce work stress but increased it, especially for women. However, it increased work engagement in men and reduced perceived job insecurity in women. These results suggest the need for targeted use of expressive writing and indicate a possible zigzag pattern of emotional response. The results could not be confirmed based on the JD-R model, indicating either insufficient operationalization or lack of alignment with the theorical model.
Temporal integration as an adaptive process in visual perception, attention, and working memory
Authors: Akyurek Elkan G.
Published: June 2024

I propose that temporal integration is ubiquitous in visual perception, because it serves an adaptive role. To support this idea, I draw together evidence from historically separated research fields that target different timescales. At one extreme, this concerns the detection and discrimination of successive stimuli within intervals of less than a quarter of a second. At an intermediate level, associated with attentional episodes, intervals between half a second up to a few seconds are considered. Finally, at the other extreme, this involves high-level, conceptual events across intervals of multiple seconds or even minutes. Across such varying intervals, the nature of temporal integration and the resultant perceptual events are clearly different. I nevertheless propose that temporal integration should be understood as a continuous process that serves a common adaptive goal: To maximize the amount of useful information, at minimal costs, tailored to the observer’s current needs and circumstances. Emerging from this viewpoint are several research directions that might be pursued on the topic of temporal integration, and on its consequences for perception and memory.
The strength in mental illness: A targeted identity-reframing exercise improves goal pursuit among people who have experienced depression
Authors: Bauer Christina , Walton Gregory M , Hoyer Jürgen , Job Veronika
Published: June 2024

Widespread narratives frame mental illness as a sign of personal weakness. We theorized that these narratives impair individuals’ ability to realize their strengths and pursue their goals. To test this hypothesis, and to attain a practical intervention-tool, we developed a brief (~20-minutes), highly-scalable exercise that inverts weakness-narratives by highlighting the strengths people show contending with depression. Three large randomized-controlled experiments (Ntotal=748) show that this identity-reframing-exercise enhanced the confidence of people who had experienced depression to pursue their goals (Experiments 1a-b); and, over two weeks, the progress they reported making towards a self-selected goal from 43% to 64% (Experiment 2). Lessened stigma mediated the gain in confidence (Experiment 1b): While 71% of control-condition participants thought the strengths needed to pursue their goals did not describe people with depression well, identity-reframing reduced this to 52%. Complementing treatments of depression, efforts to invert weakness-narratives can help people recognize and access their strengths.

Published: June 2024

Helleborus purpurascens Waldst. & Kit. – a valuable medicinal and decorative plant. Biomorphological research as a component of a comprehensive study of the species is the basis for the development of a set of measures for the preservation of natural populations and for the further wide application of economic and valuable traits of plants in their cultivation. The ontomorphogenesis of H. purpurascens under culture conditions in the Sofiyivka National Dendrological Park of the National Academy of Sciences of Ukraine was investigated. It was found that at all stages of the virginal period of ontogenesis monopodial growth of the axial shoot takes place with the dominance of the apical meristem. Traumatic elimination of the apical meristem at all stages of the virginal period leads to the replacement of the axial shoot by a lateral one, but does not promote branching. In the typical course of ontogenesis, the generative period begins in the fourth year of life of individuals, after which there is a transition to the sympodial model of shoot formation. Monocarpic shoots develop according to the type of dicyclic, development according to the type of incomplete, oligo- or polycyclic are manifestations of polyvariance. Features of the structural and functional organization of monocarpic shoots are described, their morpho-structural zones are characterized. It was found that: the lower inhibition zone (LIZ) is represented by 2-3 metamers with short internodes and cataphylls with dormant buds in their axils; innovation zone (IZ) – one (2) metamer(s) with a short internode and a cataphyll with a renewal bud in its axil; middle inhibition zone (MIZ) – one (2-3) metamer with a photophilic typical leaf(s) of the middle formation; amplification zone (AZ) – inflorescences of the cymoid type. According to the nature of the location of individual structural elements of the shoot and root sphere within the adult individual, H. рurpurascens belongs to monocentric, vegetatively immobile biomorphs, the destruction of the axial part of the main shoot in which does not lead to natural vegetative reproduction and an increase in the number of individuals.

Authors: Korzhenivska Alina , Danylenko Svitlana
Published: June 2024

In the production of sourdoughs and doughs for baking bread, the main raw material is flour. To obtain a high-quality product, low-grade flour shall not be used; it must be of high activity, that is, it must have elastic gluten, high water-absorbing and gas-forming ability and low enzyme activity. All these factors give the dough certain structural-mechanical properties during ripening of the sourdough and dough, standing and baking.

For the study, two samples (sample 1 and sample 2) of rye flour from producers in the Kyiv and Kirovograd regions and one sample of wheat flour (sample 3) from producers in the Kyiv region were selected.

Sensorial indicators were determined in the samples, namely aroma, color, crunch, taste, pest infestation, physical and chemical indicators: humidity, grind size, acidity. The quality of the raw materials used in the study was analyzed using generally accepted and special methods.

The flour samples 2 and 3 have shown the highest protein content, namely 8,9 % and 11,1 %, respectively, the lowest protein content 8,4 % was in sample 1. The energy value of wheat flour was 50,24 kcal and 42,58 kcal than in samples 1 and 2, respectively. A sensorial assessment of flour samples showed that all samples were free of foreign odors, had a pleasant aroma, and had a color characteristic of the nature of the grain, no mechanical impurities were observed.

All types of flour had a uniform degree of grinding. Wheat flour showed the lowest dispersion (largest coarseness), and rye flour of both brands had high dispersion, its effect upon the quality of the finished product being positive. Rye flour samples had 11,1-13,4 % higher water absorption coefficient compared to wheat flour. The acidity of rye flour was higher than that of wheat flour. The total gas formation during 5 hours of fermentation for sample 3 was 1430 cm 3 of CO 2 per 100 g of flour; for rye flour, sample 2 was 678 cm 3 of CO 2 per 100 g of flour.

Therefore, for the development of sourdough technology based on rye flour, coarse rye flour from the manufacturer’s plant in the Kirovograd region shall be recommended, which was the optimal in terms of granulometry, contained more starch, monosaccharides, disaccharides and protein, was optimal in terms of technological properties and had greater water absorption capacity than wheat flour.

Diphtheria is a contagious and potentially fatal disease caused by Corynebacterium diphtheriae, a bacterium widely recognised for producing a potent exotoxin, and this disease has reemerged in Nigeria. In July 2023, the Nigeria Centre for Disease Control and Prevention (NCDC) published a report confirming an increase in Diphtheria cases in some states, especially in children between 1 and 14 years, the age group primarily affected by the disease. To battle the resurgence of Diphtheria, the NCDC started particular response activities, including training in the affected states, routine immunization, and media partnership. The Federal Ministry of Health also joined hands with the NCDC to plan and enact mass vaccination campaigns, among other key interventions. However, these efforts to curb the resurgence of diphtheria in Nigeria have been met with some challenges such as vaccination gaps, poor management and diagnosis of diphtheria cases, and inadequate strategies for timely response. As a form of a way forward for the prevention and management of diphtheria, effective collaboration, strategic increase in diphtheria booster vaccination in traced contacts, and vaccination in high-risk populations, mass education and sustainable practices are essential. There is also a need to ensure adequate access to vulnerable populations, especially the rural areas.

Transatlantic Relations in the Light of the US’s Withdrawal from the Iran Nuclear Deal
Authors: Levchenko A. V
Published: June 2024

The article presents an analysis of the political divisions between the United States and its European allies concerning the U.S. withdrawal from the Joint Comprehensive Plan of Action (JCPOA) on the Iranian nuclear program. The first section of the article elucidates the key aspects of the research program, which is grounded in the theoretical framework of neoclassical realism to interpret the goal-setting and motivations of European participants' actions. The subsequent section delineates the circumstances surrounding the U.S. departure from the Iranian nuclear agreement, while the third part outlines the context and manifestations of foreign policy responses by European participants of the JCPOA, offering initial conceptual insights into challenging the U.S. exit from the Agreement. The article suggests that emerging contradictions stem from varying assessments by partners regarding the international-political ramifications of the JCPOA's breakdown and conflicting interests among involved parties. The response of European allies (EU/E3) was influenced by specific conditions at that time, shaping responsive actions and reaction forms based on a set of political and economic factors. In these circumstances, European participants aimed at a) maintaining constructive politico-diplomatic relations with Iran and fostering multilateral cooperation; b) sustaining mutually beneficial trade and economic ties, alongside established infrastructures for engagement with Iran.

Published: June 2024

Autonomous vehicles (AVs) represent a transformative shift in transportation, promising faster transit, enhanced safety, and reduced accidents. Leveraging the Vehicular Ad-Hoc Network (VANET) for communication among vehicles and roadside units, AVs exchange critical information to optimize driving conditions. However, the constant communication necessitates robust security measures to safeguard both the network and the vehicles themselves. This paper delves into the various cyber threats facing AVs and proposes countermeasures to mitigate them. A comparative analysis identifies prevalent attacks such as Denial of Service (DoS), Sybil, Spoofing, Replay, and Blackhole attacks as the most prominent in AV environments. Subsequently, protocols aimed at thwarting these common attacks are examined. However, it is noted that these protocols may fall short in cases where physical tampering compromises the vehicle’s systems. To address this vulnerability, a novel countermeasure involving cryptographic key management for system access control is proposed and discussed. Additionally, the reliability of each countermeasure is evaluated to ensure robust protection against evolving threats.

Nowadays, efficient management of energy consumption is crucial for the sustainability of our cities, and overall of our planet. Approaches investigated so far, mostly adopt complex approaches, often based on deep learning, which have an important footprint. This study focuses on the importance of using simpler methods to predict energy consumption in smart buildings, emphasizing a methodological approach that prioritizes simplicity, transparency, and computational efficiency, especially when data is scarce. It emphasizes that even the prediction of energy consumption at the scale of a building, which is sometimes ignored due to computational complexity, is feasible and can make a big difference. By using simple analytical models combined with outlier detection, this research contributes to the field by showing how we can still gain valuable insights with limited data. Therefore, this study provides a practical and scalable way to improve energy efficiency and sustainability in buildings, which has a significant contribution to energy management practices.

Magnesium is a lightweight metal with an impressive strength-to-weight ratio and is easy to use. This makes it highly desirable in the transportation industry, particularly for applications in which energy conservation and emissions reduction are key priorities. In recent decades, significant advancements have been made in magnesium-based composites, particularly with the introduction of magnesium matrix nanocomposites. These composites achieved enhanced strength through the incorporation of nanoparticles, while maintaining the original toughness of the matrix. This effectively bridges the gap between strength and flexibility, which is often observed in conventional magnesium composites. This breakthrough in the field of magnesium matrix nanocomposites (MMNCs) represents a new era of material development. However, Mg still faces challenges that hinder its widespread adoption. These include limited elasticity and ductility, susceptibility to creep and wear, and high corrosion rate. This study investigates the impact of the processing parameters on the friction stir processing (FSP) of AZ91 and a Mg alloy reinforced with MoS2. Notably, this experiment used the hole technique instead of the more common groove method. While the groove method dominates FSP applications, this project employs a 2 mm drill technique. The optimal processing conditions were as follows: rotation speed of 1100 rpm, travel speed of 15 mm/min, load of 10 kN, and use of a tungsten carbide tool material owing to its exceptional strength and durability. The surface microstructures and tensile strengths of the FSP-treated areas were analyzed further.
