Trauma in Schools: A Review of the Impact of Childhood Trauma and Assessment of a Potential Intervention
Authors: Schafer Emily
Published: May 2024

According to the National Survey of Children’s Health (NSCH), nearly 30 million children in the United States have experienced one or more types of significant childhood trauma. In the average public school, this statistic translates to as many as half of the students in a given teacher’s classroom. Children exposed to the toxic stress of trauma often experience negative consequences that affect their academic, psychological, socioemotional, and behavioral health. To aid educators in addressing this reality, trauma-informed care practices have increasingly begun to be translated into professional development opportunities for educators. Using the theoretical frameworks of trauma theory and transformational learning theory, this review of the literature provides a brief overview of trauma theory, the short- and long-term effects on children, the mechanisms involved in how trauma affects developmental outcomes, and the relevance of trauma in an educational setting. It also reviews the implementation of trauma-informed care as professional development in educational settings, examines research on educators’ awareness of beliefs and attitudes, and reviews how/whether knowledge and change in attitudes affect behavioral change.
Digital Health Interventions for Chronic Wound Management: A Systematic Review and Meta-Analysis
Authors: Bai Xinrui , Zhang Hongyan , Jiao Yanxia , Yuan Chenlu , Ma Yuxia , Han Lin
Published: May 2024

Background

Digital health interventions (DHIs) have shown promising results for the management of chronic wounds. However, its effectiveness compared to usual care and whether variability in the type of intervention affects wound outcomes are unclear.

Objective

The main objective was to determine the effectiveness of DHIs on wound healing outcomes in adult patients with chronic wounds. The secondary objectives were to assess if there was any variation in wound healing outcomes across the various types of DHIs.

Methods

In total, 9 databases were searched for the literature up to August 1, 2023. Randomized controlled trials (RCTs), cohort studies, and quasi-experimental studies comparing the efficacy of DHIs with controls in improving wound outcomes in adult patients with chronic wounds were included. Study selection, data extraction, and risk of bias assessment were conducted independently by 2 reviewers. We assessed the quality of each RCT, cohort study, and quasi-experimental study separately using the Cochrane risk of bias tool, ROBINS-I, and the Joanna Briggs Institute Critical Appraisal tools checklists. Relative risks (RRs) and 95% CIs were pooled using the random effects model, and heterogeneity was assessed by the I2 statistic. Subgroup analysis and sensitivity analysis were also performed.

Results

A total of 25 studies with 8125 patients were included in this systematic review, while only 20 studies with 6535 patients were included in the meta-analysis. Efficacy outcomes in RCTs showed no significant differences between the DHIs and control groups in terms of wound healing (RR 1.02, 95% CI 0.93-1.12; P=.67) and all-cause mortality around 1 year (RR 1.08, 95% CI 0.55-2.12; P=.83). Compared with the control group, the use of DHIs was associated with significant changes in adverse events (RR 0.44, 95% CI 0.22-0.89; P=.02). Subgroup analysis suggested a positive effect of the digital platforms in improving wound healing (RR 2.19, 95% CI 1.35-3.56; P=.002). Although meta-analysis was not possible in terms of wound size, cost analysis, patient satisfaction, and wound reporting rates, most studies still demonstrated that DHIs were not inferior to usual care in managing chronic wounds.

Conclusions

The findings of our study demonstrate the viability of adopting DHIs to manage chronic wounds. However, more prominent, high-quality RCTs are needed to strengthen the evidence, and more detailed clinical efficacy research is required.

Retrospecting Digital Media Use, Negative Emotions, and Trust Gaps During the COVID-19 Pandemic in China: Cross-Sectional Web-Based Survey
Authors: Wei Lu , Huang Qing
Published: May 2024

Background

Retrospecting the trust gaps and their dynamics during the pandemic is crucial for understanding the root causes of postpandemic challenges and offers valuable insights into preparing for future public health emergencies. The COVID-19 pandemic eroded people’s trust in strangers and acquaintances, while their trust in family members remained relatively stable. This resulted in 2 trust gaps, namely, the family members–strangers trust gap and the family members–acquaintances trust gap. Widening trust gaps impede social integration and undermine the effective management of public health crises. However, little is known about how digital media use shaped trust gaps during a pandemic.

Objective

This study aims to investigate the relationships between digital media use, negative emotions, the family members–strangers trust gap, and the family members–acquaintances trust gap during the COVID-19 pandemic in China. We test the mediating role of negative emotions between digital media use and 2 trust gaps and compare the indirect effect of digital media use on 2 trust gaps through negative emotions.

Methods

A cross-sectional web-based survey was conducted in China between January 31, 2020, and February 9, 2020. A total of 1568 adults participated in the survey. Questions related to digital media use, negative emotions, trust in family members, trust in acquaintances, and trust in strangers during the pandemic were asked. Regression analyses were performed to test the associations between the examined variables. We used a 95% bootstrap CI approach to estimate the mediation effects.

Results

Digital media use was positively associated with negative emotions (B=0.17, SE 0.03; P<.001), which in turn were positively associated with the family members–strangers trust gap (B=0.15, SE 0.03; P<.001). Likewise, digital media use was positively associated with negative emotions (B=0.17, SE 0.03; P<.001), while negative emotions were positively associated with the family members–acquaintances trust gap (B=0.08, SE 0.03; P=.01). Moreover, the indirect effect of digital media use on the family members–strangers trust gap (B=0.03, SE 0.01; 95% CI 0.01-0.04) was stronger than that on the family members–acquaintances trust gap (B=0.01, SE 0.01; 95% CI 0.003-0.027).

Conclusions

The results demonstrate that negative emotions resulting from the frequent use of digital media are a key factor that accounts for the widening trust gaps. Considering the increasing reliance on digital media, the findings indicate that the appropriate use of digital media can prevent the overamplification of negative emotions and curb the enlargement of trust gaps. This may help restore social trust and prepare for future public health crises in the postpandemic era.

Authors: Sezgin Emre , Kocaballi A Baki , Dolce Millie , Skeens Micah , Militello Lisa , Huang Yungui , Stevens Jack , Kemper Alex R
Published: May 2024

Background

Health outcomes are significantly influenced by unmet social needs. Although screening for social needs has become common in health care settings, there is often poor linkage to resources after needs are identified. The structural barriers (eg, staffing, time, and space) to helping address social needs could be overcome by a technology-based solution.

Objective

This study aims to present the design and evaluation of a chatbot, DAPHNE (Dialog-Based Assistant Platform for Healthcare and Needs Ecosystem), which screens for social needs and links patients and families to resources.

Methods

This research used a three-stage study approach: (1) an end-user survey to understand unmet needs and perception toward chatbots, (2) iterative design with interdisciplinary stakeholder groups, and (3) a feasibility and usability assessment. In study 1, a web-based survey was conducted with low-income US resident households (n=201). Following that, in study 2, web-based sessions were held with an interdisciplinary group of stakeholders (n=10) using thematic and content analysis to inform the chatbot’s design and development. Finally, in study 3, the assessment on feasibility and usability was completed via a mix of a web-based survey and focus group interviews following scenario-based usability testing with community health workers (family advocates; n=4) and social workers (n=9). We reported descriptive statistics and chi-square test results for the household survey. Content analysis and thematic analysis were used to analyze qualitative data. Usability score was descriptively reported.

Results

Among the survey participants, employed and younger individuals reported a higher likelihood of using a chatbot to address social needs, in contrast to the oldest age group. Regarding designing the chatbot, the stakeholders emphasized the importance of provider-technology collaboration, inclusive conversational design, and user education. The participants found that the chatbot’s capabilities met expectations and that the chatbot was easy to use (System Usability Scale score=72/100). However, there were common concerns about the accuracy of suggested resources, electronic health record integration, and trust with a chatbot.

Conclusions

Chatbots can provide personalized feedback for families to identify and meet social needs. Our study highlights the importance of user-centered iterative design and development of chatbots for social needs. Future research should examine the efficacy, cost-effectiveness, and scalability of chatbot interventions to address social needs.

Published: May 2024

Using quantum algorithms to improve deep learning models' capabilities is becoming increasingly popular as quantum computing develops. In this work, we investigate how quantum algorithms using quantum neural networks (QNNs) might enhance the effectiveness and performance of deep learning models. We examine the effects of quantum-inspired methods on tasks, including regression, sorting, and optimization, by thoroughly analyzing quantum algorithms and how they integrate with deep learning systems. We experiment with Estimator QNN and Sampler QNN implementations using Qiskit machine-learning, analyzing their forward and backward pass outcomes to assess the effectiveness of quantum algorithms in improving deep learning models. Our research clarifies the scope, intricacy, and scalability issues surrounding QNNs and offers insights into the possible advantages and difficulties of quantum-enhanced deep learning. This work adds to the continuing investigation of quantum computing's potential to advance machine learning and artificial intelligence paradigms by clarifying the interaction between quantum algorithms and deep learning systems.

Published: May 2024

The prevalence of highly marbled cattle breeds, such as Wagyu, has increased in the US due to consumer demand for higher-quality beef. The ability to grade highly marbled carcasses accurately and consistently, particularly with quantifying intramuscular fat content for validation, remains a challenging task for the Wagyu beef industry. New camera grading technologies have been proposed by VIAS VBG 2000 (e+v Technology GmbH & Co. KG, 2021), Meat Image Japan (MIJ), and MasterBeef (MB) for Wagyu-influenced beef carcass assessment based on advanced image analysis. However, the intramuscular fat measurements of these camera technologies and the actual percent intramuscular fat (%IMF) in the longissimus at the 12/13th rib have yet to be investigated. Chilled carcasses (n = 173) from F1 Wagyu cattle were ribbed between the 12th and 13th ribs, and the left carcass sides were imaged with the E+V, MIJ, and MB cameras. Additionally, the marbling score was assigned by a team of 3 US Department of Agriculture (USDA) graders. Samples from the longissimus thoracis were collected, and the %IMF of the muscle was determined in triplicate. Linear regressions and descriptive statistics were done using JMP (Statistical Discovery, NC, USA) software. Camera fat-related measurements were linearly correlated, and R2 was calculated. The E+V camera had the highest %IMF predictability of all cameras (P < 0.0001) using the marbling score (R2 = 0.6450) estimate. The MIJ camera presented prediction accuracy between the other 2 technologies (P < 0.0001) of %IMF with identical R2 for fat percent and fat score estimates (R2 = 0.5952). The MB camera had the lowest predictability (P < 0.0001) of %IMF using the measured marbling score (R2 = 0.3269), marbling area (R2 = 0.3333), and marbling percent (R2 = 0.3269) estimates from the instrument. As technology advances, new technologies will provide alternative means for grading Wagyu-influenced carcasses. Additionally, these findings could aid the implementation of the USDA pilot program for remote carcass grading.

The utilization of learning media is a valuable instrument in enhancing the learn-ing process, hence maximizing the attainment of learning objectives. The objec-tive of this study is to create an educational tool for biology instruction in the form of a website chatbot focused on plant tissue content. The research also seeks to evaluate the viability and efficacy of this tool when used by students. The pre-sent study used the ADDIE model, a widely recognized framework in the field of development research. This model encompasses five distinct stages, namely anal-ysis, design, development, implementation, and evaluation. The data utilized in this study was collected via interviews, questionnaires, and tests, and afterwards analyzed employing qualitative and quantitative descriptive statistical methods. The present study developed an educational tool in the form of a website chatbot focused on plant tissue materials. The validation process involved obtaining feed-back from media experts, material experts, and students. The assessment con-ducted by media experts resulted in a 91% rating, categorizing the chatbot as "very feasible." Similarly, the material expert's assessment yielded an 86.5% rat-ing, also falling into the "very feasible" category. Furthermore, students' respons-es indicated a 97.7% rating, categorizing the chatbot as "very feasible." Moreo-ver, based on the study conducted to evaluate the efficacy of learning media goods, the t-test findings revealed a significant difference between the pretest and post-test scores, as indicated by a Sig value (2-tailed) of 0.000, which is less than the predetermined significance level of 0.05. The mean gain for the website chat-bot learning media product is 0.77, falling inside the "high" category. This sug-gests that the product is very suited and effective as a learning medium.

Authors: Fairuzzabadi F. , Samsurijan Mohamad Shaharudin , Syarifah Rahmawati  , Hamat Zahri , Effendi Rustam
Published: May 2024

This study explores the "Can Do" and "Will Do" elements of human capital that impact university performance. Human capital, comprising both "Can Do" and "Will Do" elements, plays a pivotal role in driving organizational success, particularly in academic institutions. To investigate these elements within the university context, we conducted an exploratory qualitative research design using semi-structured face-to-face interviews with 12 purposely selected university practitioners and experts. The study results show that a high knowledge level, skills, capabilities, and experiences characterize the "Can Do" mindset. In contrast, the "Will Do" attitude encompasses personal traits, achievement motivation, and engagement with the job and institution. In conclusion, this research underscores the importance of cultivating a synergistic relationship between human capital's "Can Do" and "Will Do" aspects for driving sustainable improvements in university performance. By leveraging these insights, academic institutions can optimize their resources and empower their faculty to achieve greater success and impact.
Quantifying invasion dynamics: qPCR vs. ddPCR in monitoring the alien invasive red-blood mysid Hemimysis anomala and its interaction with perch in Lake Geneva
Authors: MELLITI Sirine , Vautier Marine , CHARDON Cécile , JACQUET Stéphan
Published: May 2024

1. Invasive alien species constitute a major threat for aquatic systems
due to their potential impact on endemic biodiversity, ecosystem
functioning, infrastructure, and possible sanitary issues. It is
therefore crucial to obtain information on their presence, abundance and
distribution. 2. The red blood mysid Hemimysis anomala, which originated
from the Ponto Caspian area, has recently settled in western European
lakes, including Lake Geneva. 3. Although divers have frequently
reported the presence and development of this small crustacean over the
last decade, no monitoring has yet been proposed. 4. During a period of
2.5 years, we tested and optimized an eDNA approach by comparing two PCR
techniques, quantitative and digital droplet PCR, to assess the
presence, abundance and dynamics of the animal as well as that of a
potential predator, the perch (Perca fluviatilis). 5. We show and
discuss the efficiency of the methods and reveal for the first time the
seasonal dynamics of Hemimysis anomala at a selected site in Lake
Geneva. We highlight, in agreement with diving observations that the
animal’s abundance is high in winter and declines rapidly in early
spring, concomitantly with temperature increase and perch presence.

Authors: Moura Sebastião Wendell Nobres , Santos Raphael Di Carlo Silva , Picanço Giorgio Arlan da Silva , Teixeira Mayara Fraeda Barbosa , Machado Jean Ricardo Mesquita
Published: May 2024

The geomagnetic field produces aeronomic phenomena according to the Earth’s magnetic latitude. In South America, we find two important phenomena: the South America Magnetic Anomaly (SAMA) and the Equatorial Electrojet (EEJ). This study aimed to analyze the amplitudes of continuous magnetic pulsations (Pc3 and Pc4 type) in magnetic stations located between EEJ and SAMA. Based on the Dst index, we acquired data from four monitoring stations on quiet and disturbed days in August 2018. The magnetic pulsations in the equatorial region are related to the type of ionospheric conductivity, such as Cowling’s conductivity, contributing to amplifying the damping of Pcs wavelength. Finally, we found evidence that suggests a potential influence of the EEJ behavior on the amplitudes of Pc3 and Pc4. Therefore, the present study contributes to future research to fully understand the nature and extent of this influence.
A Decade of Airglow Observation of Mesospheric Fronts over the Brazilian Equatorial Region
Authors: Carvalho Emanuel Barbosa de , Paulino Igo , Wrasse Cristiano Max
Published: May 2024

Mesospheric fronts were observed over São João do Cariri (7.4ºS, 36.5ºW), in the northeast region of Brazil, from September 2011 to June 2021 using an all sky airglow imager. The occurrence of the mesospheric fronts presented a well defined seasonality  with maximum in the Spring period of ten consecutive years. In addition, an anisotropy was observed in the preferential propagation direction, in which most of the front propagated to the northeast. These results suggest that the seasonality and anisotropy can be produced due to either the location of sources or the filtering process associated with the wind system. Other important aspects like the statistics of trailing waves and ripples observed simultaneously were reported as well.
Assessing Time-Lapse Full-Waveform Inversion Strategies in a Brazilian Pre-Salt Setting
Authors: Hochwart Brenno , Silva Sérgio Luiz E.F. da , Cetale Marco , Moreira Roger Matsumoto
Published: May 2024

We conducted a comparative study of time-lapse full-waveform inversion (time-lapse FWI) strategies, considering a typical deep-water Brazilian pre-salt setting. This study employed a realistic P-wave model, ocean bottom nodes (OBN) acquisition, noisy data, and a Gaussian anomaly to represent time-lapse model changes. We evaluated the four most commonly used time-lapse FWI schemes. In the first, known as parallel time-lapse FWI, two independent FWI processes are performed from the same initial model, utilizing baseline and monitor datasets. In the second strategy, namely sequential time-lapse FWI, the retrieved baseline model serves as the starting model for inverting monitor data. In both cases, the time-lapse model is derived by subtracting the retrieved baseline model from the retrieved monitor model. The remaining two methods were double-difference and central-difference time-lapse FWI. Our findings demonstrate that all these schemes can detect model variations of 3%. Remarkably, the central-difference time-lapse FWI method demonstrated superior accuracy in producing time-lapse models and, as such, presents itself as a promising strategy for implementation in time-lapse studies within Brazilian pre-salt regions.
The effect of pre-vulcanized latex usage on Marshall characteristics and stiffness modulus in hot mix asphalt wearing course (AC-WC) mixtures
Authors: Ramadhani Ramadhani , Arliansyah Joni , Kadarsa Edi
Published: May 2024

Flexible pavement itself uses asphalt binder as a binding material between aggregates, but with the increasing number of vehicle loads, the ability of flexible pavement needs to be improved. A rubber is a natural polymer material that can be used to improve asphalt mixtures’ performance. This paper aims to analyze the effect of using pre-vulcanized latex on characteristics in hot mix asphalt wearing course mixtures. Pre-vulcanized latex is used as a substitute material for asphalt binder at levels of 7% and 9% by weight. Based on Marshall test results, the AC-WC mixture using pre-vulcanized latex achieved Marshall stability of 11.63 kN or increased by 32.28% at 7% content, while at 9%, it resulted in Marshall stability of 10.69 kN or increased by 21.06%, compared to the specification limit, which is 8.83 kN. The stiffness modulus test results of the asphalt mixture showed that at a temperature of 25°C, there was an increase of 17.46% and 28.26%, respectively, when using pre-vulcanized latex at levels of 7% and 9%. These findings indicate that the use of pre-vulcanized latex as a partial replacement for asphalt has a positive impact on temperature changes in the pavement material.

In this paper, we work on the existence of approximate solution for the fixed
point equation Rx + Qx = x, when R is a weak contractive mapping and Q is a
continuous self-map which is a new topic related to the background
literature. Till now, no results were found to find the existence of
approximate solution for such a kind of mappings in literature to the best
of our knowledge. Here we prove the existence of best proximity point for
the sum of a weak contractive non self map and a continuous self map. Also,
we provide an example to support our main theorem. And also, we prove the
existence of best proximity point for the sum of Geraghty-contraction and

In this article, we first obtain an identity that we will use throughout the
article. With the help of this equality, new inequalities involving a real
parameter are established for Riemann-Liouville fractional integrals. For
this purpose, properties of the differentiable convex function, H?lder
inequality, and power-mean inequality are used. In addition, new results are
established with special choices of parameters in all proven inequalities.
Our results are supported by examples and graphs. It is shown that some of
these results generalize the trapezoid type and Newton-type inequalities.
Analytical and numerical discussion for the quadratic integral equations
Authors: Abdel-Aty M.A. , Abdou M.A.
Published: May 2024

In this work, we study the existence of at least one solution of the
Quadratic integral equation with Phase-lag term. Our proof depends on a
suitable combination of the Darbo?s fixed point principle and the technique
of measures of noncompactness. Homotopy perturbation method is presented to
obtain an approximate solution of Quadratic integral equation with Phase-lag
term. Convergence and error estimate of Homotopy perturbation method are
obtained. Homotopy perturbation method is a powerful device for solving a
wide variety of problems. It gives excellent flexibility to the expression
of the solution and how the solution is explicitly obtained, and provides
great freedom in choosing the base functions of the desired solution and the
corresponding auxiliary linear operator of homotopy. These methods produce
the solutions in terms of convergent series without needing to restrictive
assumptions, to illustrate the ability and credibility of the methods, we
deal with two examples that show simplicity and effectiveness.

A crisis of moral ecology: Magar agro-pastoralism in Dhorpatan Hunting Reserve, Nepal
Authors: Rai Indra Mani
Published: May 2024

Prior political ecology studies have explored the vulnerability of pastoralism and conflicts between protected areas and pastoralist livelihoods. Some conservation regimes regard Indigenous pastoralists’ institutions, knowledge, self-governance and self-determination as incompatible with contemporary conservation on the grounds that the associated practices are unsustainable. Based on critical ethnography, this paper examines the moral ecology of Indigenous Magar agro-pastoralism in the Dhorpatan Hunting Reserve of mid-western Nepal. Traditional Magar management is in crisis due to reserve policies and practices. From a political ecology perspective, I show that the traditional moral ecology of agro-pastoralism sustains complex relationships with the rangelands. Traditional institutions uphold a moral ecology that is deeply rooted in spiritual practices and fosters a sense of responsibility for the preservation of biodiversity and nature. Current conservation policies inadequately recognise these Indigenous moral principles and weaken harmonious socio-ecological relations. In order to manage protected areas sustainably in high-altitude regions, it is crucial to manage agro-pastoralism within the framework of traditional moral ecology through Indigenous peoples’ self-governance and self-determination.
Nudging to glory: the World Heritage Convention’s influence in conflict-prone Global South natural sites
Authors: Chakraborty Pallabi , Ghosh Sonali
Published: May 2024

The paper explores the role of the UNESCO World Heritage Convention in safeguarding natural and cultural heritage, with a specific focus on sites facing armed conflict. The Convention acts as a global mechanism for the protection and conservation of sites with Outstanding Universal Value. The study investigates the use of ‘soft power’ and ‘nudging’ strategies by the World Heritage Committee to facilitate the restoration of World Heritage Sites facing threats, particularly in the Global South. The analysis is based on the examination of 32 natural sites inscribed on the List of World Heritage in Danger since 1984, nine of which are in the Global South and faced with armed conflict. Case studies illustrate how armed conflicts impact biodiversity and the steps taken to recover these sites. The study emphasises the soft power of the World Heritage Convention, backed by diplomatic ties and financial aid, as instrumental in achieving restoration. Nudging is observed in the strategic alignment of choices to encourage conservation efforts. The findings suggest that the World Heritage Committee’s influence extends beyond conservation, contributing to regional development, especially in the Global South. However, challenges persist, and the paper calls for a continuous evolution of the World Heritage Convention’s role in addressing conflicts, development, and climate change to ensure effective global heritage conservation.

Synchronization Functions of “Mickey-Mousing” in Animation Film Rhapsody Rabbit
Authors: Fadly Alvriza Mohammed , Supiarza Hery , Pawitan Zakiah
Published: May 2024

Synchronization between visual animation and music has been widely known as mickey-mousing. Notable old animation films have used this particular technique to reinforce action with a musical flourish and convey a certain meaning. Furthermore, animation music is commonly based on popular music, such as The Hungarian Rhapsody No.2 in Rhapsody Rabbit. The music is utilized not just as a scoring aspect but to dictate every Bugs Bunny's action when playing the piano. This research aims to study the implementation of the mickey-mousing technique in Rhapsody Rabbit film. It uses a qualitative content analysis approach to analyze visual and aural aspects—primary data is sourced from the Rhapsody Rabbit film and the Hungarian Rhapsody No. 2 music sheet. Secondary data is collected from literature studies related to the topic. Data collection is conducted through observation, interview, and documentation study. The data is analyzed using Klaus Krippendorf's content analysis technique which divided into six steps. The result of this study is that the mickey-mousing technique is implemented through a combination of a fast pace of visual and musical play altogether. Animation adapts to several parts of the musical composition so that articulation, illustration, and accentuation occur as a function of the mickey-mousing technique.
Effectiveness of virtual reality-supported exercise therapy in improving upper extremity function and activities of daily living among patients after stroke: a systematic review of randomized control trials

This systematic review describes the effectiveness of virtual reality (VR)-supported exercise therapy on upper limb motor function and activities of daily living after stroke. Studies published through January 24, 2022, were identified using CINAHL, Cochrane Library, Embase, Medline, and Web of Science. Randomized control trials comparing VR treatment with conventional therapy (CT) for upper extremity rehabilitation after stroke were included. Methodological quality was assessed using the Cochrane risk-of-bias tool. Of 9 included studies, 5 concluded that the VR group outperformed control participants, 1 indicated the superiority of VR-supported exercises alone over CT, and 3 found VR comparable to CT in promoting upper limb motor function. Five studies analyzed independence in daily living, with 4 reporting no significant difference between VR and CT groups. No strong evidence indicated long-term benefits of VR-assisted exercise. All included studies demonstrated low risk of bias concerning random sequence generation, allocation concealment, outcome assessment blinding, incomplete outcome data, and selective reporting bias. However, a high risk of bias was observed regarding participant blinding due to the nature of the intervention. Most studies suggested that VR, used alongside CT, can improve motor function following stroke. However, the evidence was insufficient to conclude that VR outperforms conventional approaches.

Single case report of a middle-aged patient with Kartagener’s syndrome who experienced recurrent paroxysmal supraventricular tachycardia. Despite optimized beta-blocker therapy, only cardioversion in emergency departments provided symptomatic relief. The unique electrocardiographic features of this condition and their significance in transaortic electrophysiological studies for diagnosis and treatment are highlighted.
State policy of supervision and control regarding compliance with labour discipline of employees and its implementation
Authors: Kucher Oleksii , Mohilevskyi Leonid
Published: May 2024

Research issue: The study is driven by contemporary global challenges regarding the stability and efficiency of production processes, the necessity to enhance competitiveness, and ensuring workplace safety, which demands a systematic approach to monitoring and supervising adherence to labour discipline. The research is theoretical in nature. The aim/objective of the study is to analyse the specifics of state policy on supervision and control over employees’ adherence to labour discipline, the peculiarities of its practical implementation, and perspectives for improvement. Method: The study employed a logical-semantic method, analytical and documentary methods of analysis, and the method of expert assessment of labour discipline of employees and employers based on their evaluation of certain aspects of labour discipline. The research methodology included a sample size of 30 respondents, and the research instrument was expert evaluation. Data collection was conducted through surveys, and the calculation method was quantitative. Results: The article examines the impact of the main incentives and methods on ensuring labour discipline, determining their essence and forms of manifestation. It also considers the extent of application of each method in enterprise practices. It was found that economic methods are widely used and aimed at increasing employee motivation and maintaining their labour discipline. The analysis revealed that the main manifestations of employee labour discipline and managerial duties are differences in the perception of labour discipline by both parties. It was found that employers underestimate the productivity and abilities of employees, indicating potential systemic deficiencies in human resource management. Conversely, employees note that managers ignore their needs and problems. The results of the expert evaluation showed that employees rated their discipline higher than employers did. These discrepancies in evaluations could affect internal relations within the team and require managerial attention to improve interaction and cooperation. Conclusion: Based on the assessment of labour discipline, systemic deficiencies in human resource management were identified, highlighting the need for appropriate monitoring and employee motivation mechanisms. The study proposes innovative personnel management methods to ensure labour discipline in enterprises, including HR branding, team building, mentoring, and grading. It is proven that these approaches allow for the creation of a fundamentally new management system to ensure compliance with labour discipline and the development of professionalism and employee motivation.

Luminescence dating of Quaternary sediments – some practical aspects
Authors: Moska Piotr
Published: May 2024

Luminescence dating is based mainly on the dosimetric properties of quartz and feldspar. These minerals are among the most popular found on Earth, resulting in the possibility of using luminescence methods in practically any environment. Currently, quartz remains the best recognized mineral in terms of dosimetric properties, particularly with regards to results obtained for quartz grains, which are regarded as being the most reliable in luminescence dating. Supporters of luminescence methods are constantly growing, however, these groups do not always have sufficient knowledge to avoid even the most basic of issues that may be encountered overall – from the process of sampling through to the awareness of what a single luminescence result represents. The present paper provides an overview of several practical aspects of luminescence dating such as correct sampling procedures and all necessary information regarding the calculation of the dose rate and equivalent dose with particular reference to potential problems that occur when the age of the sample is being determined. All these aspects are crucial for obtaining a reliable dating result, on the other hand, they remain a potential source of uncertainty.
