Violence in contact and custody proceedings-Acase of child endangerment in the family court-Where are efficient child protection measures?

Against the background of 30years of discussion in medicine and law about unfounded accusations and the existence of reasonable suspicion of intra-family violence in contact and custody proceedings, this article emphasises the importance of focusing on child protection by all professionals.Based on acase report in connection with the Federal Ministry of Justice's handout "Dealing with violence in custody and contact proceedings", the article describes the relevance of child protection in Austrian case law and the means by which it is undermined. In the name of science, ideological diagnoses are used instead of evidence-based treatment diagnoses [1]. "Professionals from the healthcare system, youth welfare, justice and education should cooperate in child protection with the aim of recognising, identifying and ending child abuse, maltreatment and/or neglect as such (cf. §3 KKG) [2]."In legal practice, however, practitioners in the psychosocial, psychosomatic and psychotherapeutic fields are often not recognised as witnesses because of the assumption they are influenced by parents or patients themselves. In Austria, the evaluation of evidence is the responsibility of the judge and it is often assumed that practitioners cannot take an objective position towards their patients and their relatives. Specialist medical or psychological experts are therefore of crucial importance. When taking their oath, they have committed themselves to objectivity and impartiality in the recording of findings and orientation towards scientific principles and standards ("state of the art") and their application, as well as to continuous further training and education in the preparation of expert opinions [3].The specific case in question is achild with adiagnosis of post-traumatic stress disorder following suspected sexualised violence, enuresis and enkopresis in connection with the traumatic experiences.The connection between violent situations and child and adolescent psychiatric disorders and the course of the custody and contact proceedings are described. Relevant legal interests such as the will of the child, the best interests of the child, attachment tolerance and protection against violence are addressed and put up for discussion. Topics such as domestic, psychological, sexualised, institutional violence and intimate terror are presented.The case report is an example of how child psychiatrists deal with points relevant to the Federal Ministry of Justice's handbook "Dealing with violence in custody and contact proceedings", which was published in January 2024. It represents aguideline for the area of court proceedings, assessment and treatment.

Tracing the technological trajectories of smart logistics domain based on citation analysis and topic modelling

ABSTRACT The emergence and development of intelligent technology are triggering major changes in the logistics industry, and relevant scientific and technological research on smart logistics (SL) is emerging endlessly. However, there is no research that systematically explores SL from the technological perspective. Therefore, this article selects 47,253 documents retrieved from the Derwent Innovation Index for systematic analysis and provides a comprehensive understanding of the SL domain. We combine main path analysis (MPA) and LDA topic modelling approaches to identify technological evolution trajectories. Through three main paths, the key technologies and technological evolution directions in the SL domain are revealed. Through topic identification and topic correlation calculation, global topic popularity trends and local topic evolution paths are identified. Finally, this study summarises our findings, contributions, and limitations. This is the first attempt to detect key technologies in the SL domain through MPA and topic analysis, thereby guiding relevant researchers and enterprises.

Promoting sustained access to cognitive behavioral therapy for insomnia in Australia: a system-level implementation program.

Insomnia is a highly prevalent and debilitating disorder. Cognitive behavioral therapy for insomnia (CBTi) is the recommended 'fist line' treatment, but is accessed by a minority of people with insomnia. This paper describes a system-level implementation program to improve access to CBTi in Australia to inform CBTi implementation in other locations. From 2019 to 2023, we conducted a program of work to promote sustained change in access to CBTi in Australia. Three distinct phases included 1) Scoping and mapping barriers to CBTi access, 2) Analysis and synthesis of barriers and facilitators to devise change goals, and 3) Structured promotion and coordination of change. We used a system-level approach, knowledge brokerage, and co-design, and drew on qualitative, quantitative, and implementation science methods. We identified barriers to CBTi access from the perspectives of people with insomnia, primary care clinicians, and the health system. A stakeholder advisory committee was convened to co-design change goals, identify modifiable barriers, devise program logic and drive change strategies. We commenced a program to promote system-level change in CBTi access via; improved awareness and education of insomnia among primary care clinicians, self-guided interventions, and advocating to Government for additional CBTi funding mechanisms. This implementation program made significant progress toward improving access to CBTi in Australia. Ongoing work is required to continue this program, as long-term system-level change requires significant and sustained time, effort and resources from multiple stakeholders. This program may be used to inform CBTi implementation activities in other locations.

Morphological characteristics of talocalcaneal coalitions: Anatomical observation, finite element analysis and clinical application

BackgroundThe intricate anatomical structure of talocalcaneal coalitions (TCCs) presents significant challenges for clinicians in both diagnosis and treatment. This study aimed to investigate the anatomy, imaging characteristics, and biomechanical properties of TCCs, providing essential references for contemporary clinical diagnosis, treatment, scientific research, and education regarding TCCs. MethodsThe morphologies of TCCs were examined and classified in intact dry osseous specimens from 131 Asian adults. The imaging characteristics of TCCs were summarized by carefully observing the X-rays and CT scans. Additionally, finite element models of TCCs were established and validated, allowing for the simulation and analysis of stress and strain. ResultsThe TCCs were primarily located in the region between the posterior end of sustentaculum tali (ST), the medial port of the tarsal canal, and the medial edge of the posterior talar articular surface (PTF). In comparison to specimens with cartilage and ligament connections, the medial tubercle of osseous connections exhibited significant inward and downward protrusion, while the ST was longer and thicker. Statistically significant differences were noted in the widths of the calcaneus and talus, as well as in the thickness and length of the ST (P < 0.05). CT imaging provided an accurate determination of TCCs’ locations, while X-rays revealed the presence of the “C sign” and “duck beak sign” in all osseous connection specimens. Finite element model analysis indicated that stress was primarily concentrated at the osseous connection, which also reduced displacement of the subtalar joint. ConclusionsThe comprehension of the precise location, anatomical morphological characteristics, imaging features and finite element mechanical properties of TCCs is instrumental in enhancing the diagnosis and treatment of TCCs.

Dreaming conundrum.

Dreaming, a common yet mysterious cognitive phenomenon, is an involuntary process experienced by individuals during sleep. Although the fascination with dreams dates back to ancient times and gained therapeutic significance through psychoanalysis in the early twentieth century, its scientific investigation only gained momentum with the discovery of rapid eye movement (REM) sleep in the 1950s. This review synthesises current research on the neurobiological and psychological aspects of dreaming, including factors influencing dream recall and content, neurophysiological correlates, and experimental models, and discusses the implications for clinical practice.

Optimized protocol for the multi-omics processing of cryopreserved human kidney tissue.

Biobanking of tissue from clinically obtained kidney biopsies for later use with multi-omic and imaging techniques is an inevitable step to overcome the need of disease model systems and towards translational medicine. Hence, collection protocols ensuring integration into daily clinical routines using preservation media not requiring liquid nitrogen but instantly preserving kidney tissue for clinical and scientific analyses are of paramount importance. Thus, we modified a robust single nucleus dissociation protocol for kidney tissue stored snap frozen or in the preservation media RNAlaterand CellCover. Using porcine kidney tissue as surrogate for human kidney tissue, we conducted single nucleus RNA sequencing with the Chromium 10X Genomics platform. The resulting data sets from each storage condition were analyzed to identify any potential variations in transcriptomic profiles. Furthermore, we assessed the suitability of the preservation media for additional analysis techniques (proteomics, metabolomics) and the preservation of tissue architecture for histopathological examination including immunofluorescence staining. In this study, we show that in daily clinical routines the RNAlater facilitates the collection of highly preserved human kidney biopsies and enables further analysis with cutting-edge techniques like single nucleus RNA sequencing, proteomics, and histopathological evaluation. Only metabolome analysis is currently restricted to snap frozen tissue. This work will contribute to build tissue biobanks with well-defined cohorts of the respective kidney disease that can be deeply molecularly characterized, opening new horizons for the identification of unique cells, pathways and biomarkers for the prevention, early identification, and targeted therapy of kidney diseases.

Improving horizon computation algorithm with quasirandom sequences

The topographic horizon can be used to estimate shading for applications requiring an accurate solar resource estimate, including the effects of the local terrain. With high-resolution topography data, horizon estimation significantly contributes to the computation time needed for irradiance simulations. Approximate horizon algorithms have been proposed previously, sampling topography in a finite number of directions. This paper extends this idea by presenting a sampling approach based on the quasirandom sequences. The sampling strategy is optimized with 300,000 km2 of topography data from Europe and the USA. We demonstrate that our algorithm is several orders of magnitude faster than the precise horizon calculation and significantly improves the previous approximate algorithms. In particular, at the ground level with a topography resolution of 1 m/pixel, the proposed method achieved the same accuracy as the old approximate method four times faster. The horizon is one of the key methods in geographical information science and a part of many modeling tools in the built environment. Improvements in computation time benefit all applications that require irradiance modeling, e.g., the yield of vehicle- and building-integrated photovoltaic or temperature modeling of buildings.

Academic freedom: Global variations in norm conceptualization, diffusion and contestation – an introduction

Abstract This Introduction provides an overview of the topics covered in this special issue on ‘Academic freedom: Global variations in norm conceptualization, diffusion and contestation’, which explores what academic freedom means, how this may vary on a global level, how the norm spread around the world and what current contestations look like. The Introduction defines some terms essential to this debate, such as the freedom of science, academic freedom, freedom of scientific research and the right to science, and offers an analytical framework for the various contributions of the special issue. This includes, in particular, a distinction between illiberal and liberal science scripts and their relationship with academic freedom, as well as between different forms of contestations and limitations of academic freedom. Authors from varying disciplinary and regional backgrounds address different aspects of this theme in their respective contributions, of which the introduction gives a brief summary.

Growth-phase-dependent control of rRNA synthesis in Saccharomyces cerevisiae.

Saccharomyces cerevisiae is one of the most well-studied model organisms used in the scientific community. Its ease of manipulation, accessible growth conditions, short life cycle, and conserved eukaryotic metabolic pathways make it a useful model organism. Consequently, yeast has been used to investigate a myriad of phenomena, from microbial to human studies. Most of the research performed using this model organism utilizes yeast cell populations when they are growing exponentially, a growth phase aptly termed exponential or log phase. However, log phase encompasses several yeast generations and ranges several hours of yeast growth, meaning that there is a potential for variability during this "homogenous" growth phase. Cells in log phase require robust ribosome biogenesis to support their rapid growth and cell division. Interestingly, during log phase, ribosomal RNA (rRNA) synthesis (which is the first and rate limiting step in ribosome biosynthesis) has been shown to decrease prior to growth rate decline in stationary phase. In this study, we utilized several genomic and biochemical methods to elucidate the relationship between subphases of log phase and rRNA synthesis. Our results indicate that as yeast cells progress through subphases of log growth, both polymerase I transcription and rRNA processing are repressed. Overall, this study establishes a growth-phase-dependent control of rRNA synthesis that unexpectedly begins prior to the switch to stationary phase (i.e., pre-diauxic shift) as a putative mechanism of anticipating nutrient starvation.IMPORTANCESaccharomyces cerevisiae is a ubiquitously used model organism in a wide range of scientific research fields. The conventional practice when performing yeast studies is to investigate its properties during logarithmic growth phase. This growth phase is defined as the period during which the cell population doubles at regular intervals, and nutrients are not limiting. However, this growth phase lasts hours and encompasses several yeast cell generations which consequently introduce heterogeneity to log growth phase depending on their time of harvest. This study reveals significant changes in the transcriptomic landscape even in early stages of exponential growth. The overall significance of this work is the revelation that even the seemingly homogenous log growth phase is far more diverse than was previously believed.

Echo of extinction: The Ivory-billed Woodpecker's tragic legacy and its impact on scientific integrity

Abstract Among the current surge in extinction rates, exceeding between 100 and 1000 times the prehuman background rate, a multitude of species quietly fade away, largely escaping the notice of our collective awareness. The extinction of only a select few species has the power to captivate public attention, stir emotions, and ignite debates comparable to the case of the ivory-billed woodpecker (Campephilus principalis). Reports purporting a rediscovery of this long-extinct species periodically surface and find their way into peer-reviewed journals, attracting worldwide attention from the public media. This phenomenon persists despite a glaring lack of evidence supporting such an exceptional claim, in disconnect with principles of population biology or even common sense, thereby risking erosion of public trust in the foundations of nature conservancy and the integrity of scientific methodologies in general. The tragic fate of this iconic species therefore holds significance beyond ecology, providing deep insights into extinction and conservation while highlighting the need for refinement of scientific rigor and standards of evidence in the peer review process and beyond.

Boron Salicylate Ester Compounds as Boron Therapeutics. Their Synthesis, Structural Characterizations and Anticancer Effects against MDA-MB-231.

The element boron forms a wide range of borate minerals with different properties. Borate minerals make it possible to design boron-containing molecules with new biological properties in terms of their chemical structure and properties. It is known that boron compounds have antioxidant, anti-inflammatory, anti-tumor and anti-cancer properties. This makes boron compounds important for the future development of boron chemotherapeutics, boron supplements and new drugs. Reliable scientific studies on boron compounds will facilitate the clear presentation of their functions in its biological applications and metabolism. In this study, boron monoester and boron diester structures were synthesized with salicylic acid ligand. To stabilize boron ester structures, Na+, K+, Mg2+, Ca2+ cations were used as counter-ions. Structural properties of the synthesized substances, molecules obtained by crystallization/precipitation from aqueous solutions in solid state, elemental analysis, melting point determination, infrared spectroscopy analysis (FT-IR), thermal analysis (TGA/DTA), mass analysis (GC-MS) and single crystal analysis. Structural properties were tried to be explained by structure analysis (SC-XRD) methods. Additionally, the anticancer potential of boron salicylate esters against the MDA-MB-231 human breast adenocarcinoma cell line was examined. The K-B salicylate diester molecule was found to have the most potential potency with the lowest IC50 value against the MDA-MB-231 cell line. The anticancer potential of boron salicylate esters can be further investigated with other cancer models with the combination of anticancer drugs. It is also thought that the mechanism of action of these molecules may help reveal their further applications.

Roles of defects in perovskite CsPbX3 (X=I, Br, Cl): a first- principles investigation

Inorganic lead halide perovskite CsPbX3 (X=I, Br, Cl) have a promising application in optoelectronic fields due to their excellent photovoltaic properties. The defects, which have a significant impact on the performance of materials, are often introduced during the synthesis process. However, there is still a lack of systematic theoretical investigation of the effects of these defects. In this study, the effects of vacancies and H-atom interstitial point defects on the structural, electronic and optical properties of CsPbX3 are systematically investigated by using first-principles approach based on density-functional theory. The calculated results show that the introduction of different defects have significantly effect on the band gap, effective mass, semiconductor properties, ion migration and optical absorption coefficient of the perovskite materials. It is also found that VCs and VPb defects introduce shallow transition levels that do not negatively impact the optoelectronic properties. However, VX and interstitial H defects generate deep transition levels within the bandgap, which acts as non-radiative recombination centers and reduce the optoelectronic performance of the perovskite material. This study contributes to the understanding of the nature of halide chalcogenides and optimally regulating the performance of optoelectronic devices.

Buckwheat containing-bread: a scientific inquiry into insulin, polyphenols, antioxidants status, and oxidative stress markers in type-II diabetic individuals

Buckwheat grains contain bioactive components with known effects on cardio-metabolic biomarkers. Previous research on oxidative stress markers made exclusively from wheat flour or two-hour postprandial levels of antioxidant status, plasma total polyphenols, and advanced glycation end products (AGEs) were considerably higher than fasting values after consuming buckwheat-incorporated bread (BWB), including clinical, animal, and epidemiological studies, suggesting the potential of buckwheat intake to influence parameters such as polyphenol intake, antioxidant status, insulin levels, and oxidative stress markers. However, the specific impact of buckwheat-containing bread on these biomarkers in individuals with type-II diabetes remains a significant gap in our understanding. Our current work aims to address this gap by exploring the effects of buckwheat-containing bread on insulin levels, polyphenol intake, antioxidant status, and markers of oxidative stress. In a randomized crossover study, 16 individuals with type-II diabetes were assigned to consume control bread made exclusively from wheat flour or bread incorporating 50% buckwheat flour. The research followed a crossover design, with a period of one to two washout interventions. Test breads were given at breakfast following a 12 h fast the previous night. After 2 h of bread intake, blood samples were collected at baseline (fasting). The two-hour postprandial levels of antioxidant status, plasma total polyphenols, and advanced glycation end products (AGEs) were significantly higher than fasting values after consuming buckwheat-incorporated bread (BWB). This suggests that the buckwheat-containing bread improved plasma total polyphenol levels and total antioxidant status. Our research concludes that the intake of bread containing buckwheat positively influences polyphenols in plasma and the status of antioxidants. This suggests that incorporating buckwheat into bread may have favorable effects on biomarkers associated with cardio-metabolic health in individuals with type-II diabetes. By addressing these knowledge gaps, our research aims to inform and engage the scientific community in further exploration of the potential health benefits of buckwheat-containing bread.

RNA transcription assisted universal CRISPR/Cas12a system for programmable analysis of multiple colorectal cancer-associated microRNAs

Accurate analysis of multiple microRNA (miRNA) levels is significantly valuable for early diagnosis of colorectal cancer noninvasively considering the miRNA expression is highly relevant to the occurrence and progression of cancer. However, the low abundance and high sequence homology of miRNAs make their precise determination extremely challenging. Here, we developed a universal and programmable diagnostic strategy allowing for analyzing multiple colorectal cancer-associated miRNAs. The system combined sequentially programmable rolling circle transcription (RCT) and the CRISPR/Cas12a system with high trans-cleavage activity to achieve highly sensitive and specific detection of four target miRNAs. Owing to the remarkable performance of universal RCT-Cas12a strategy, this biosensor could detect miR-21, miR-17, miR-31 and miR-92a with a LOD of 2.1, 1.6, 3.7 and 1.0 pM, respectively. This strategy had a unique advantage in distinguishing human normal colon epithelial cells lines (NCM460) from human colon cancer cells (HT29). In particular, the designed system exhibited superior analytical capability in distinguishing paracancerous and colorectal cancer tissues from patients undergoing colorectal cancer surgery. This arbitrarily programmable, scalable, fast and specific strategy potentially offered an attractive alternative to handle varied challenges encountered with CRISPR-based systems, and held immense promise in scientific research and clinical applications.

Using immersive virtual environments for teaching and socializing children with autism spectrum disorder

The authors' research interests are focused on the development of preschool children with autism spectrum disorder and the potential of virtual reality technologies for teaching and developing children in a gaming environment. The article reviews articles published in peer-reviewed journals and posted in the Scopus database and the Google Scholar search engine for scientific publications over the past 10 years. The objective of the review is to identify international research experience regarding the impact of virtual environments and hardware on children with autism spectrum disorder, their potential effectiveness, recommended conditions and limitations of using virtual reality for social adaptation, development of communication, cognitive and motivational skills. The articles analyzed in the review focus on the following issues: the potential and results of using different types of virtual reality technologies for developing various skills and abilities in children with autism; using virtual reality to work with problems and risks; as well as the features, limitations and safety of using virtual reality headsets by children with autism spectrum disorder. It is recommended to use immersive virtual environments for children with autism under the following conditions: the presence of close and trusted people (caregivers or parents), the presence of real game objects for switching children after exiting the virtual environment and distracting attention from possible negative effects of using gadgets, continuing communication with the child after a virtual reality session in a normal physical space to practice the skill being taught, specific time limits for staying in the virtual environment, etc. It is concluded that the results of using virtual reality technologies remain contradictory, but valid data from scientific research allow us to assert that the use of immersive virtual environments is acceptable, can be effective for teaching children with autism spectrum disorder and, if certain conditions are met, is adequately perceived by them.

THE ROLE OF THE EUROPEAN UNION IN ACHIEVING SUSTAINABLE DEVELOPMENT AT THE GLOBAL LEVEL

In the context of globalization and demographic change, states are currently more vulnerable to non-military, asymmetric, hybrid and cyber threats and threats from non-state actors. Russia's war on Ukraine, Hamas's military attack on Israel indicate the likelihood of armed aggression against the sovereignty and territorial integrity of the state in modern global conditions. In the introductory part of the paper, the author analyzes the notion of national security as the ability of states, taking into account global changes and development, to protect their own identity, survival and interests. Furthermore, the author analyzes the need to achieve Sustainable Development at the global level. In the final part of the paper, the author states that Investing in the common future with its closest neighbors is fundamental for the long-term political stability of the European Union itself. Therefore, the enlargement of the European Union is based on development programs aimed at achieving political stability, secure economic conditions, social cohesion and environmental sustainability. The content will be created based on the analysis of foreign literature and using electronic content. In preparing the content of the paper, the author will apply the general scientific methods: the descriptive method, the normative method, the comparative method and the content analysis method as a special scientific method.
