Labelling kelps with 13C and 15N for isotope tracing or enrichment experiments v1
Authors: Kuech Anton , Witte Ursula
Published: April 2024

Isotope tracing experiments can be used to trace organic material flow through the ecosystem by artificially adding labelled biomass into a system. The advantage of this process is the direct control of carbon and nitrogen addition to the system for measuring uptake rates by consumers which can substantially reduce the uncertainties associated with food web models. This protocol details the steps involved in successfully culturing and isotopically enriching (13C & 15N) juvenile sporophytes of two common North Atlantic kelp species (Laminariales): Saccharina latissima and Laminaria digitata. A first-order successful isotopic enrichment study of S. latissima, as well as the first inclusion of 15N enrichment for L. digitata, is detailed. This protocol provides a comprehensive description of the stable isotope enrichment process in two kelp species, potentially serving as a foundation for its application in other macroalgal taxa.
Analysis of remaining useful life of slope based on nonlinear wiener process
Authors: Huang Ming , Yu Weihai , Yang Fan
Published: April 2024

A remaining useful life (RUL) prediction model based on the nonlinear Wiener process is proposed to better tackle the life evaluation problem in the slope degradation process. Taking the displacement of the slope as its performance degradation index, and the nonlinear Wiener process is used to establish the RUL prediction model of the slope. For this model, the least squares method (LSM) is used to estimate the drift coefficients, the maximum likelihood estimation method (MLEM) is used to estimate the diffusion parameters, and then the probability density function (PDF) of the RUL of the slope is deduced and the RUL is predicted. The proposed model is verified by slope engineering examples. The results demonstrated that the RUL of the degradation model based on the nonlinear Wiener process has a greater prediction accuracy than the linear Wiener process. Because the various nonlinear functions have varying slope adaptations, and it can predict the RUL of a slope more accurately, which can provide more reliable preventive maintenance decisions.

Published: April 2024

The results of the analysis of monitoring data of the Kuibyshev reservoir, as a source of domestic and drinking water supply, for the period 2000-2018 are presented. It has been established that in summer, during the period of massive development of cyanobacteria, biological pollution of the reservoir is observed, the quality of water deteriorates in terms of smell, color, pH, and dissolved oxygen content. During the period of deterioration in the quality of water in the water supply source in large Volga cities, problems arise in purifying natural water to meet the requirements of the drinking water supply of the population. To solve the problem, recommendations have been developed to improve the technological scheme for purifying Volga water from organic and toxic substances.
Experimental and statistical models moisture release of the mixture treated with reagents raw sludge and compacted active sludge
Authors: Kichigin Viktor I. , Yudin Alexander A.
Published: April 2024

The technology of changing the resistivity of a mixture of raw sludge and compacted activated sludge taken after the sludge pumping station of urban sewage treatment plants by treating the sludge with aluminum sulfate and polyacrylamide (PAA) in doses from 0 to 300 mg/dm3 has been tested. The degree of influence of each reagent on the process of dehydration of the sediment under study has been established. It has been shown that PAA has about 2.0 times greater effect on the process of moisture loss than Al2(SO4)3 at reagent doses from 0 to 200 mg/dm3 and about 1.5 times – at doses from 100 to 300 mg/dm3. Mathematical models of the dependence of the change in the resistivity of the sediment on the amount of Al2(SO4)3 and PAA introduced into it are obtained. Mathematical models are also presented in graphical form (isolines). The optimal doses of coagulant and flocculant for chemical treatment of the studied sewage sludge were determined.

Authors: Kazantsev Dmitriy I. , Ochkurenko Aleksandr A. , Peleganchuk Vladimir A. , Batrak Yurii M.
Published: April 2024

A literature review of the clinical efficacy of various methods of local cryotherapy after knee endoprosthesis in the early postoperative period is presented. A literature search using the keywords “cryotherapy” and “knee arthroplasty” was conducted in the databases Medline.Ru, CyberLeninka, E-Library, PubMed, and Cochrane. The search date was January 7, 2023. The review included studies that assessed the effectiveness of cryotherapy after knee replacement in the early postoperative period. After electronic search, 562 abstracts were found, and 16 studies were included in the review. Although the patients had similar characteristics, significant heterogeneity was noted in the studies according to cryotherapy modality, duration, and frequency of cold exposure. This may have been the reason for the contradictory results of the review. It is challenging to draw a clear conclusion on the advantages and disadvantages of using cryotherapy after knee replacement. Thus, high-quality studies should examine the effectiveness of cryotherapy.

Authors: Kudashev Dmitry S. , Svetlova Galina N. , Sefedinova Maria Yu. , Zuev-Ratnikov Sergey D. , Knyazev Andrey A.
Published: April 2024

BACKGROUND: The combined course of avascular necrosis of the femoral head and septic arthritis of the hip joint is extremely rare and not always timely diagnosed. Analysis of specialized foreign literature revealed only single descriptions of clinical cases of combined lesions of the hip joint (avascular necrosis of the femoral head and septic arthritis). However, these studies do not describe the surgical treatment algorithms of patients. While analyzing the sources of domestic literature for the last 10 years, we did not encounter descriptions of such clinical cases.
CLINICAL CASE DESCRIPTION: A 38-year-old patient was diagnosed with avascular necrosis of the femoral head with concomitant septic arthritis of the hip joint. During the preoperative period, a diagnostic puncture of the hip joint with subsequent cytologic and microbiological examination of synovial fluid was performed. Growth of the Staphylococcus aureus strain was observed. Because primary hip arthroplasty was contraindicated and isolated conservative treatment of bacterial arthritis aggravated the course of avascular necrosis, the patient underwent two-stage surgical treatment. The first stage was femoral head resection with installation of a spherical cement spacer impregnated with antibiotics, and the second stage was total hip arthroplasty after the inflammatory process had subsided. The postoperative period of each surgical stage proceeded without complications. It was possible to achieve microorganism eradication; eliminate the chronic inflammatory process, which was confirmed clinically and laboratory; ensure the possibility of total hip arthroplasty; and restore the limb-bearing capacity, extent of motion in the joint, and quality of life of the patient.
CONCLUSION: The clinical observation confirms the need for detailed diagnosis in patients with an atypical course of avascular necrosis of the femoral head and demonstrates a successful treatment option in such cases.

Crowding and diastema are common malocclusion conditions that occur due to a discrepancy between tooth size and jaw size. The treatment that can be done is based on the severity of the case. Mild cases of malposition can be treated with removable orthodontic appliances. This article aims to show the analysis how an active plate device with a simple spring was used to treat multiple maxillary diastemas and anterior crowding of the mandible. The patient complained that his upper front teeth gap and his lower teeth were crowded. It does not interfere with the appearance, but sometimes open food is tucked between the front teeth. The patient has never used an orthodontic appliance before. Molar relation: Malocclusion Angle class 1 type dental with mild individual tooth malposition. Twenty-two treatment visits were performed. Treatment was carried out using an active plate with a simple spring on teeth 13, interdental 31-41, and 43; retentive components using Adam Clamer on teeth 16, 26, 36, and 46; long labial arch with U loops on the right and left permanent 1st premolar teeth. In the 22nd control, the results showed that teeth 11, 21, and 43 malpositions were corrected, and the diastema was closed on tooth 14 against 13 and tooth 21 against 22. In addition, the width of the diastema on interdental 13-12, 12-11, and 22-23 was reduced to 0.05 mm. An active plate with a simple spring can correct diastema and mild crowding of the anterior teeth

Abstract
Petra Djurhuus is the first person from the Faroe Islands who gained education within conservation and museum work. She became part of Føroya forngripagoymsla (the Faroese museum) when it was re-established in 1928 og soon became a leading force in the reorganization and development of the museum. Yet Petra Djurhuus is quite absent in the Faroese museum history. The aim of this paper is to examine her diverse work within the field and to reflect on her position as a woman in the museum world at that time. Petra Djurhuus studied in Denmark and had strong ties with colleagues form Danish museums. It therefore offers relevant context to view her story in a larger museal framework focusing on women working at Danish museums in the early 20th century.
Utilizing Digital Thermal Monitoring (DTM) to Measure Reactive Hyperemia of Type 1 Diabetes Mellitus on Cardiovascular Endothelial Function
Authors: Schuppenhauer Mary Elizabeth
Published: April 2024

The role of type 1 diabetes mellitus (T1DM) on the female cardiovascular system remains largely a mystery. However, it is widely accepted that insulin plays a role in cardiovascular protection. Hemoglobin A1C levels allow for further understanding of glucose impact upon endothelium and endothelial function in young females currently utilizing continuous glucose monitoring (CGM) along with insulin therapy. Flow-mediated dilation provides images of the dilation of the brachial artery under shear stress. The control group, those without a diagnosis of T1DM, are expected to have lower levels of hemoglobin A1C. The experimental group, women with T1DM, experienced significantly higher hemoglobin A1C levels and along with vascular reactivity index (VRI) scores than the control group. This finding has future influences in female cardiovascular health, protection of endothelium, and the wider debate over the influence T1DM and tighter controls of glucose regulation have on endothelial health.

A significant number of studies have been focused on the issue of occupational burnout among medical personnel, but none of the papers addresses this problem with respect to speech therapists. Speech therapists practicing a profession whose essence is working with people, providing help, exposure to the expectations of patients and their families, are exposed to the appearance of symptoms of occupational burnout. In addition, the nature and specificity of the speech therapist’s work in the departments of neurology and neurological rehabilitation can significantly affect the development of burnout syndrome. The aim of the study was to assess the degree of occupational burnout among speech therapists working in the departments of neurological rehabilitation and neurology, as well as to find out its causes. If the speech therapist is at risk of burnout, it is important to determine what the risk depends on and how to counteract it.

Published: April 2024

One of the symptoms of cerebral palsy is muscle tone disorder hencethe disorder of facial muscles. The disorder of facial muscles is connected with the supranuclear damage to the so-called bulbar pathways, with involuntary movements of these muscles that continue beyond the period of physiological occurrence in the form of motor automatisms associated with eating. Therefore the tactile stimulation and massage of certain parts of the face, around the mouth, jaws, nose and cheeks, play such an important role in the rehabilitation of children with CP. It is important because facial muscles take part in the necessary movements of eating, taking bites and keeping them in the mouth in the right position. Those processes affect the development of masticatory organ (jaws and teeth) and take active part in the shaping of motor speech mechanisms and producing sounds of speech. The aim of the paper is to discuss tactile stimulation on the example of Elena Archipowa’s method.

The article presents the course of the treatment and improving the treatment of the four-year old boy born with van der Woude syndrome. The combination of the congenital defects that occur in this particular case of the syndrome are the complete cleft lip, alveolus and palate, salivary fistula on the bottom lip and considerable shortening of the tongue frenulum. Anatomical malformations in the child’s facial skeleton disturbed the development of the child’s speech, which in turn influenced his general development. Many years’ process of the boy’s treatment engages various specialists where each of them has played an important role. The crucial roles have been of a surgeon, an orthodontist, a phoniatrist, a laryngologist, a psychologist and a speech therapist. Coordinated cooperation of those specialists facilitates planning and implementing the adequate treatment and speech therapy forms. The progress the child has made proves that the treatment has been right and effective and that in this case the multi-specialist proceedings are necessary.

Modern devices facilitating childcare, such as car seats, deckchairs, walkers, or multimedia devices – smartphones, tablets and television, in addition to performing the function for which they were created – ensuring the child’s safety and keep their attention occupied, can also be the cause of some additional, unwanted consequences. Those side effects mostly concern movement restrictions, visual field limitations, maintaining position unnatural for the developmental stage, or reducing the number of verbal and non-verbal interactions with the parent. This is associated with potential disorders of developmental trajectories – delayed achievement of basic milestones, and with dysfunctions in forming of the correct sensory integration, maturation of the child’s vestibular system and, as the further consequence – problems associated with the proper development of speech. The article attempts to analyze existing literature connected to the impact of vestibular system on proper language development and on the creation of a sensory integration. In addition, it concerns the problem of so-called container baby syndrome – a set of developmental threats associated with leaving a child for too long inside such baby accessories as car seats, deckchairs, walkers or with too early exposure to multimedia. The results of authors own research on knowledge among the students, about the dangers of abuse of positioning devices and multimedia in childcare were also presented.
The Risk Perception as a Mediator Between Herding and Overconfidence on Investment Decision by Gen Z in Indonesia
Authors: Kaban Lila Maria , Linata Evita
Published: April 2024

Behavioral finance theory highlights how psychological factors can lead to poor investment decisions, which may threaten investors' trust in the stock market, discourage investments, and hinder economic growth. This study aims to examine how behavioral finance factors, particularly herding bias and overconfidence bias, influence investment decision on the Indonesia Stock Exchange through risk perception. The research was conducted using an online questionnaire distributed to 120 Gen Z stock investors and analyzed using PLS-SEM. The results show that herding and overconfidence biases have a significant positive influence on risk perception. Both herding and overconfidence biases have indirect positive influences on investment decision through risk perception. Although overconfidence bias and risk perception can directly affect investment decision, herding bias fails to do so. These findings highlight the importance of considering an individual's behavioral biases and risk perception, while policymakers should devise strategies to mitigate their impacts; so that investors can benefit from investing, which may eventually lead to the growth of the national economy

Background and Purpose:People with Parkinson’s disease (PD) are at risk for stigma. The stigma theory suggests four stigma types: public stigma, self-stigma, stigma by association, and structural stigma. The purposes of this study were to understand how people with PD and caregivers perceived and experienced stigma, review the literature and scan social media for evidence of stigma and PD, and examine the interrelationships between stigma types.Methods:This was a multicase, qualitative, descriptive research study. Cases included interviews with people with PD and caregivers, a literature review, and a scan of social media posts for evidence of stigma. Literature and social media were searched; seven people with PD and five caregivers completed the interviews. The stigma theory guided the analysis. Methods to ensure trustworthiness were employed.Results:Public stigma, self-stigma, stigma by association, and structural stigma were evident in the literature and described by caregivers. Public stigma, self-stigma, and structural stigma were described by people with PD. Public stigma was represented in social media posts. Interrelationships between public and self-stigma, public stigma and stigma by association, and self-stigma and structural stigma were identified.Implications for Practice:All stigma types were experienced and negatively affected people with PD and caregivers. Lack of knowledge and awareness caused stigma and should be addressed on multiple levels. Stigma experienced by people with PD was a global phenomenon; therefore, nurses internationally must be aware of their perceptions of and behavior toward people with PD. Engaging the public with people with PD will demystify PD and reduce stigma. Greater understanding of structural stigma and diverse populations’ and public perceptions is needed.

Elastic, Electronic, Dynamic and Thermodynamic Properties of YbPdH3
Authors: Al Selgin
Published: April 2024

A comprehensive computational investigation has been carried out for
YbPdH3 via first principles calculations for the first time. Structural, electronic and
thermodynamic properties are obtained. The obtained lattice constant of YbPdH3 is
in a good agreement with the existing literature. Subsequently, the elastic constants
are obtained and used to compute several parameters such as anisotropy, hardness,
Cauchy pressure, shear and Young modulus, machinability index and Poisson’s ratio.
According to Born stability criteria, YbPdH3 is mechanically stable material. Cauchy
pressure and Poisson’s ratio indicates ductile nature. The anisotropy factor
indicates anisotropic nature almost in every direction for Young modulus, shear
modulus, linear compressibility and Poisson’s ratio. The machinability index (B/C44)
is found to be 2.88 whereas Vickers hardness of YbPdH3 is computed via Chen’s
model as 2.965. The electronic band structure of YbPdH3 demonstrates metallic
characteristics since there is no band gap between valence and conduction band.
The thermodynamic properties such as Debye temperature, Debye vibrational
energy, vibrational free energy, entropy, heat capacity and melting temperature of
YbPdH3 are also obtained. The heat capacity seems to reach its Dulong-Petit limit at
about 300 K.
La toponimia en el maya yucateco de (i)x K’o’opch’e’en, Quintana Roo
Authors: Petatillo Chan Rodrigo
Published: April 2024

El estudio y descripción de los topónimos es uno de los temas más antiguos de la lingüística (Levinson, 2003) y la filología. Se trata de un área que nos explica la historia de una región, y a su vez describe los rasgos topográficos del paisaje. Los topónimos codifican múltiples informaciones, que un análisis lingüístico y antropológico ayuda a revelar. El objetivo de este artículo consiste en describir los topónimos del maya yucateco de Kopchen, Quintana Roo, centrándose en sus significados a través de la exposición de sus propiedades léxico-morfológicas y fonológicas. Se usó la etnografía de la comunicación (Gumperz y Hymes, 1964), empleando entrevistas semiestructuradas para la elaboración del corpus. Este artículo muestra que los morfemas que forman los topónimos nativos del maya yucateco revelan información relacionada directamente con el lugar, en contraste con los topónimos provenientes del español al maya yucateco analizados en este artículo. Todos los topónimos son multimorfémicos; los morfemas léxicos refieren a diferentes categorías de palabras. El núcleo de un topónimo resultó crucial para determinar las construcciones endocéntricas y las construcciones exocéntricas. Morfológicamente, solo se observa la marca de género femenino o individualizador (i)x y el sufijo -il en los topónimos. Fonológicamente, los topónimos prestados del español se adaptan a las reglas fonológicas del maya yucateco con alargamientos vocálicos y luego reciben los tonos. Los préstamos cada vez se vuelven más complejos de acuerdo con las diferentes producciones de los hablantes. Este artículo revela varios puntos que ayudan a la literatura en general a ampliar su conocimiento sobre la toponimia.

Cumhuriyetin ilanıyla birlikte Türk toplumu Batı dünyasıyla daha yakın ilişkiler kurmaya çalışmıştır. Bu süreçte çeviri faaliyetleri önemli bir rol oynamış ve kültürel etkileşimi artırmıştır. Osmanlı Dönemi’nde sistemli ve düzenli bir çeviri etkinliğinin bulunmamasına karşın Cumhuriyet Dönemi’nde bu konu önemli biçimde ele alınmıştır. Cumhuriyetin ilk yıllarında çeviri faaliyetlerinin genellikle edebi eserler üzerinde yoğunlaştığı görülmektedir. Özellikle Batı edebiyatının klasik eserleri Türkçeye çevrilerek yerel okurlarla buluşturulmuştur. Bu dönemde çevirmenler sadece dil engelini aşmakla kalmamış, aynı zamanda yabancı kavram ve düşünce sistemlerini Türk kültürüne aktarma görevini de üstlenmişlerdir. Türkiye'de çeviri faaliyetlerinin zaman içerisinde çeşitlendiği ve geliştiği vurgulanmaktadır. Bilim, teknoloji, hukuk ve diğer alanlardaki metinlerin çevirileri, ülke modernleştikçe giderek daha önemli hale gelmiştir. Bu dönemde özel terimlerin doğru çevirileri Türkiye’nin uluslararası entegrasyonunu desteklemiştir.

Issues of jurisdiction of disputes for arbitration proceedings. Comparative analysis of legislation of Baltic States (Latvian Republic and Estonian Republic)
Authors: Gavrilenko Vladimir A.
Published: April 2024

The issues of jurisdiction of disputes between economic entities to be solved through the institution of commercial non-state arbitration and the competence of arbitration institutions to consider certain types of disputes are analyzed. As a continuation of the publication in the previous issue of the journal, the arbitration legislation and arbitration practice of the Baltic states of the former USSR, such as the Republic of Latvia and the Republic of Estonia, were researched and the activities of local arbitration institutions. There is an influence on genesis of the above states legislation of Soviet and Russian law, as well as the legal traditions of some states of the European Union, especially the countries of Western Europe and Scandinavia. The Baltic republics are characterized by formed market economy at a relatively high level. The institution of commercial arbitration, as a means of resolving economic disputes, is also quite developed and in popular in the legal and economic systems of the above states. This publication analyses the legal issues of arbitrability of disputes in legal systems of Latvia and Estonia, national and international legislation governing these issues. Conclusions have been developed about the main advantages and disadvantages of legal regulation of institution of arbitration in above states.

Published: April 2024

Background: Latency reversing agents (LRAs) such as protein kinase C (PKC) modulators can reduce rebound-competent HIV reservoirs in small animal models. Furthermore, administration of natural killer (NK) cells following LRA treatment improves this reservoir reduction. It is currently unknown why the combination of a PKC modulator and NK cells is so potent and whether exposure to PKC modulators may augment NK cell function in some way.
Methods: Primary human NK cells were treated with PKC modulators (bryostatin-1, prostratin, or the designed, synthetic bryostatin-1 analog SUW133), and evaluated by examining expression of activation markers by flow cytometry, analyzing transcriptomic profiles by RNA sequencing, measuring cytotoxicity by co-culturing with K562 cells, assessing cytokine production by Luminex assay, and examining the ability of cytokines and secreted factors to independently reverse HIV latency by co-culturing with Jurkat-Latency (J-Lat) cells.
Results: PKC modulators increased expression of proteins involved in NK cell activation. Transcriptomic profiles from PKC-treated NK cells displayed signatures of cellular activation and enrichment of genes associated with the NFκB pathway. NK cell cytotoxicity was unaffected by prostratin but significantly decreased by bryostatin-1 and SUW133. Cytokines from PKC-stimulated NK cells did not induce latency reversal in J-Lat cell lines. 
Conclusions: Although PKC modulators have some significant effects on NK cells, their contribution in “kick and kill” strategies is likely due to upregulating HIV expression in CD4+ T cells, not directly enhancing the effector functions of NK cells. This suggests that PKC modulators are primarily augmenting the “kick” rather than the “kill” arm of this HIV cure approach.

Published: April 2024

[Purpose] This narrative review evaluated the impact of exercise on gait and cognitive functions in patients with Parkinson’s disease (PD), focusing on prefrontal cortical (PFC) activation assessed using near-infrared spectroscopy (NIRS).[Methods] A literature search was conducted in the PubMed and Web of Science databases using keywords such as “Parkinson’s disease,” “gait,” “cognitive functions,” “exercise,” and “NIRS,” focusing on publications from the last decade. Studies measuring PFC activity using NIRS during gait tasks in patients with PD were selected.[Results] The review indicated that patients with PD demonstrate increased PFC activity during gait tasks compared to healthy controls, suggesting a greater cognitive demand for movement control. Exercise has been shown to enhance neural efficiency, thus improving gait and cognitive functions.[Conclusion] Exercise is crucial for improving gait and cognitive functions in patients with PD through increased PFC activation. This emphasizes the importance of incorporating exercise into PD management plans and highlights the need for further studies on its long-term effects and the neurobiological mechanisms underlying its benefits, with the aim of optimizing therapeutic strategies and improving patients’ quality of life.
Effect of myofascial release and muscle energy technique on patients with chronic neck pain: a scoping review
Authors: Mittal Sneha , Sharma Sunita
Published: April 2024

[Purpose] To identify the effects of muscle energy techniques and myofascial release in patients with chronic neck pain.[Methods] To conduct a literature search and identification; PRISMA-ScR guidelines were followed. Relevant articles were searched for from the following medical and health sciences electronic databases: PubMed, EBSCOhost, CENTRAL of the Cochrane Library, and the Physiotherapy Evidence-Based Database (PEDro). Patients with chronic neck pain were eligible for the scoping review.[Results] Seven articles were included in this review. This scoping review found that there is heterogeneity in the prescription of MFR and MET and a greater tendency to check three major physical dimensions (pain, range of motion, and disability). Various studies have opted for distinct intervention regimens, resulting in disparities in the frequency of weekly interventions, which can range from biweekly to five times a week. These inconsistencies may lead to perplexity among practitioners, as each intervention modality demonstrates favorable outcomes for individuals with persistent cervical discomfort. Moreover, a significant proportion of research projects have employed the numeric pain rating scale (NPRS) and visual analog scale (VAS) for data quantification.[Conclusion] According to results, majority of the studies were focused on pain and missing components of range of motion and quality of life. Work-related factors can act as risk factors for chronic neck pain. Future investigations should adopt a comprehensive methodology and incorporate QoL assessments of quality of life.
Effects of verjus acidification on muscat canelli grape juice and wines
Authors: Lyne Andrew , Botezatu Andreea
Published: April 2024

Our study aimed to investigate the use of verjus (green grape juice) as an acidifying agentfor improving the overall acid profile and balance of wine, lowering the pH and alcohol content and creating a sustainable winemaking practice that can be utilised in warm grape-growing regions, such as Texas, where pH levels range from 3.5 to over 4.0 in white juice and wine. Muscat Canelli wines were produced using two different treatments for pH and acidity balance. Verjus was produced by pressing under-ripe grapes resulting from crop thinning practices and added at two different rates of 2 % and 11 % to juice obtained from ripe grapes prior to fermentation. For all the wines produced, pH, titratable acidity (expressed as g/L Tartaric Acid), alcohol, glucose-fructose, l-malic acid, tartaric acid, potassium, polyphenols were analysed, and preference testing was performed via consumer sensory panels. Results obtained indicate that verjus can be used to balance pH and acidity as well as lower alcohol content. Consumer preference ranking indicated no significant differences between any of the treatments, while acidity rankings correctly distinguished the wines according to their acid levels. This work shows that the use of verjus as a pre-fermentation acidification agent could be a potential tool for winemaking to help mitigate the negative effects associated with climate change.

Development and analysis of a Numbas diagnostic tool for use in a mathematics refresher program
Authors: Shearman Donald , Aziz Shatha , Pettigrew Jim
Published: April 2024

We describe the development and analysis of an online diagnostic tool implemented in the Numbas e-learning system and used in an Australian university mathematics refresher program. Following the rapid transition to online delivery of the refresher program caused by COVID-19, the diagnostic instruments and methods used within the pre-pandemic, in-person, version of the program were lost. In 2022, we undertook to revive them in a way that would honour their original diagnostic purpose but offer a more sophisticated approach utilising the Numbas diagnostic exam type. Improvement of the tool after its initial deployment has involved the use of Rasch-based item analysis and recursive refinement of the knowledge map underlying the items.
A Study on Police Immunity to Criminal Liability that Results from Use of Excessive Force
Authors:   Korean Association of Public Safety and Criminal Justice, Lee Hoon , Kim DongLyoul
Published: April 2024

Public distrust of police grew over two police officers’ poor response to an attempted murder case in Incheon, Korea on November 15, 2021. The incident resulted in a public outcry for police reform and measures to address police incompetence as a female officer left the crime scene while a victim was stabbed in her neck. After the incident, the Korean National Police Agency initiated a revision to the Act of the Performance of Duties by Police Officers on the ground that the potential for criminal liability from use of police force is a primary obstacle to officers’ proactive law enforcement in the field. As the National Assembly approved the revision, police officers can be immune to criminal liability or their liability can be mitigated when they meet the requirements in the immunity clause. Nevertheless, the legislation faces strong opposition as it fails to adopt the concept of objectively reasonable mistakes in use of police force situations. In this regard, the current study critically reviewed the adequacy of the immunity clause within the context of legal nature of police force, police use of force standards as well as immunity to criminal liability clauses in 41 states in the United States of America. The present study proposed several policy implications for proper use of police force including the revision of the current immunity clause, changes in police officers’ weapon carrying systems and police officer requalification systems.
Social attention in the wild - Fixations to the eyes and autistic traits during a naturalistic interaction in a healthy sample
Authors: Buehler Raimund , Silani Giorgia , Ansorge Ulrich
Published: April 2024

Attention to social stimuli is a key component of social behavior and facilitates the development of fundamental social skills. Studies investigating social attention in neurotypical or neurodiverse populations have often relied on screen-based experiments using static images or videos, which lack the sensory richness and reciprocity present in real-life social interactions. This can possibly be attributed to the challenges one encounters when creating naturalistic experiments, such as dealing with dynamically moving areas of interest (AOI’s), which require either time-intensive manual coding or restraining of participants. Here, we present findings from a paradigm using unrestrained mobile eye-tracking and a face detection algorithm (MTCNN) to measure fixation rates during a semi-structured, face-to-face interview. Data from N = 62 healthy adult participants was analyzed for gaze behavior and related to participants’ autistic traits. We observed a significant negative correlation between fixation rates on the eye region averaged over the entire interaction and scores on the autism spectrum quotient (AQ) (r = -0.14), indicating participants with high autistic traits were fixating less on the eye region. We also compared different types of interview questions (open vs. closed) to explore whether the reduction in fixation rates was more pronounced for specific time intervals during the interview. Lastly, we discuss both possibilities for extensions as well as limitations of the presented paradigm that could serve as inspiration for future research.
