Revisiting the Execution of Marinus van der Lubbe in the Context of Invitation to a Beheading: What Did Nabokov Know?
Authors: Bethea David M.
Published: January 2025

This note (zametka) presents information from the periodic press about the trial and execution of Marinus van der Lubbe for his role in the Reichstag fire of February 1933 that could have come to Nabokov’s attention—and then been reflected in his description of the poshlost’ of aestheticized violence—as he was working on the novel Priglashenie na kazn’. Especially noteworthy is the dress and ritualized behavior in the case of van der Lubbe’s executioner and the fact that in the Russian emigré press of the time the description of the condemned man’s death involved beheading by an axe and not (as in the actual execution) beheading by guillotine.

Угол обитания: Письма из Ostland’a в Ostland: 1941—1944 гг. [A Slice of Life: Letters to and from Ostland (1941—1944)]
Authors: Ravdin Boris , Musachio Benjamin
Published: January 2025

We present a selection of annotated letters from 1941 and 1944 addressed to Gennadii Ivanovich Tupitsyn (1895, Rostov-on-Don – 1966, Riga), a Riga-residing educator with diverse interests in languages, literature, and geography. This valuable, multilingual collection comprising more than fifty letters illustrates “everyday life” (“povsednevnyi byt”) in Latvia during the period of German occupation. Tupitsyn’s family, colleagues, and former students wrote to the ailing instructor about a variety of seemingly prosaic topics: ration cards, pensions, job opportunities, dental procedures, harvests, book sales, etc. The specter of war nevertheless hovers in the background (and on occasion intrudes into the foreground) of this correspondence. In annotating these letters, we rely on primary sources, particularly daily newspapers (for example Tēvija, Slovo). This emphasis on contextualizing newspapers and periodicals recreates the atmosphere of the time, primarily as seen through the eyes of the Tupitsyn extended family as well as Tupitsyn’s colleagues. We also comment on these letters’ poetics, attending to the tropes, typos, and word signals embedded in the Russian, Latvian and German originals.

Юбилейное: Неизвестное немецкое письмо Вяч. Иванова [À propos of an Anniversary: An Unknown Letter by Viacheslav Ivanov]
Authors: Wachtel Michael
Published: January 2025

The present publication consists of the sole letter written by Viacheslav Ivanov to the German archaeologist Ludwig Curtius (1874—1954). Ivanov met Curtius in 1935 through their mutual friend Ernst Robert Curtius (no relation). From 1928 to 1937 Ludwig Curtius was the head of the German Archaeological Institute in Rome, a place dear to Ivanov’s heart. After his dismissal by the Nazis in September of 1937, Curtius remained in Rome. In 1944, on the occasion of his seventieth birthday, an event was held in his honor at the Swedish (German?) Institute in Rome. It is not known whether Ivanov attended, but he did write a congratulatory letter, a copy of which remained in the family archive. In this letter, Ivanov emphazises their common conception of humanism by citing Goethe, Schiller, and (most strikingly) Mommsen.

Published: January 2025

From 2021 to 2024, balloon-borne in-situ observations were conducted to study the vertical ozone distribution over the Korean Peninsula. The electrochemical concentration cell (ECC) ozonesondes that produce high-resolution ozone profiles from the surface to 30 km based on balloon sounding and KI redox reactions were used, and a total of 123 ozone profiles were produced at Anmyeon, Osan, and Yongin sites. Consecutive daily measurements were made at the Anmyeon site, focusing on ozone transport processes through the Asian summer monsoon. Twice a day (AM, PM) measurements were done at the Yongin site to understand the diurnal cycle of ozone due to photochemical reactions and vertical transport. The ozone data were integrated into netCDF for each measurement year and location, along with the atmospheric profiles of temperature, pressure, humidity, and wind from radiosonde. The ECC ozonesonde provides ozone information with reference-level accuracy, and the data could be further used to improve satellite- and model-based ozone products.

Published: January 2025

OBJECTIVE

To assess the extent to which the concomitant presence of subclinical myocardial injury or stress and diabetes affects the risk of heart failure (HF) subtypes.

RESEARCH DESIGN AND METHODS

The Jackson Heart Study included Black adults, categorized based on diabetes status, high-sensitivity cardiac troponin I (hs-cTnI), and brain natriuretic peptide (BNP) levels. Subclinical myocardial injury was defined as hs-cTnI ≥4 ng/L in women and ≥6 ng/L in men, and subclinical myocardial stress as BNP ≥35 pg/mL. The study outcomes included incident HF, HF with preserved ejection fraction (HFpEF), and HF with reduced ejection fraction (HFrEF).

RESULTS

Among 3,484 participants (mean age 54.6 years, 63.2% women, 22.3% with diabetes, 26.4% with subclinical myocardial injury, 9.4% with subclinical myocardial stress), 306 developed HF (151 HFpEF and 139 HFrEF) over 12 years. Compared with individuals with no diabetes and no subclinical myocardial injury at recruitment, participants with diabetes and subclinical myocardial injury had a higher HF risk (hazard ratio [HR] 3.84, 95% CI 2.60–5.66), HFpEF (HR 3.68, 95% CI 2.13–6.36), and HFrEF (HR 4.26, 95% CI 2.40–7.53). The HRs associated with the presence of diabetes and subclinical myocardial stress versus their joint absence were 4.03 (95% CI 2.50–6.51), 5.71 (95% CI 3.11–10.47), and 2.13 (95% CI 0.88–5.17) for HF, HFpEF, and HFrEF, respectively. There was no significant diabetes status and cardiac biomarkers interaction.

CONCLUSIONS

Both diabetes and subclinical myocardial damage significantly increase the risk of all HF types among Black individuals.

Enhanced AdaBoostM1 with Multilayer Perceptron for Stock Price Prediction
Authors: Nabi Rebwar Mala , Saeed Soran AB. , Haron Habibollah
Published: January 2025

Stock market investment has gained significant popularity due to its potential for economic returns, prompting extensive research in financial time series forecasting. Among the predictive models, various adaptations of the AdaBoostM1 algorithm have been applied to stock market prediction, either by tuning parameters or experimenting with different base learners. However, the achieved accuracy often remains suboptimal. This study addresses these limitations by introducing an enhanced version of AdaBoostM1 (ADA), implemented on the Waikato Environment for Knowledge Analysis (WEKA) platform, to forecast stock prices using historical data. The proposed model, termed AdaBoost with Multilayer Perceptron (ADA-MLP), replaces the commonly used Decision stumps with a set of Multilayer Perceptron (MLP) models as weak learners. The experimental results demonstrate that ADA-MLP consistently outperformed the standard AdaBoostM1 algorithm, achieving an average classification accuracy of 100%, compared to 98.48% by AdaBoostM1—a relative improvement of 1.52%. Additionally, ADA-MLP demonstrated superior performance against other enhanced versions of AdaBoost presented in prior studies, achieving an average of 5.3% higher accuracy. Statistical significance testing using the paired t-test confirmed the reliability of these results, with p-values < 0.05. The experiments were conducted on the Yahoo finance dataset from 25 years of historical data spanning from January 1995 to January 2020, comprising 6295 samples, ensuring a robust and comprehensive evaluation. These findings highlight the potential of ADA-MLP to enhance financial forecasting and offer a reliable tool for stock market prediction. Future research could explore extending this approach to other financial instruments and larger datasets to further validate its effectiveness.

Authors: Khusumadewi Ari , Naqiyah Najlatun , Setiawati Denok , Pramesti Mayang , Ariyanti Vivin , Dewanti Septinda Rima
Published: January 2025

Islamic boarding schools (Pesantren) are crucial educational institutions in Indonesia, characterized by their unique learning systems, values, and diverse student demographics. However, they face challenges, such as a lack of sufficient caregivers and teachers, limiting their ability to address students' varied needs, which range across age, gender, culture, and personal concerns. This study aims to develop a peer helper model that integrates Islamic boarding school values to overcome these limitations and provide better support for students, particularly for adolescents. Using a literature review and content analysis of various reference sources, this study found that peer helpers, designed with pesantren values, offer an potential solution by addressing the students' challenges through peer relationships, which are more significant during adolescence. The peer helper model includes essential components such as selecting suitable peer helper characteristics, equipping them with necessary skills, and implementing effective support strategies. This culturally relevant model not only compensates for the limited availability and competence of caregivers and teachers but also provides a framework adaptable to other educational settings with similar issues. The integration of religious and cultural values into student support systems demonstrates the importance of culturally responsive approaches in enhancing student well-being in educational contexts.

Published: January 2025

This study investigates the impact of the Community Guidance Model on women’s empowerment in the fishing village of Nelayan, Pangandaran Regency, Indonesia. It explores how this model promotes gender equality by enhancing social support, improving resource access, and driving cultural change. Using a qualitative case study approach, the research focuses on women participating in the community guidance program, selected through purposive sampling. Data collection methods included in-depth interviews, participant observations, and analysis of program documents. Thematic analysis revealed that the Community Guidance Model significantly strengthens social support networks, grants women greater access to economic and educational resources, and fosters a shift in cultural norms that traditionally limit women’s roles. These changes enable women to take on active roles within their communities, enhancing both their welfare and social standing. The study concludes that the Community Guidance Model is an effective strategy for empowering women in fishing villages, offering a pathway to sustainable gender equity and social inclusion. These findings support the expansion of such programs to achieve lasting improvements in the well-being and agency of women across Indonesian coastal communities.

Published: January 2025

This study explores the dynamics of social anxiety among first-year university students, focusing on the challenges they face and the adaptations they employ. The primary objective is to understand how specific factors influence students' anxiety levels, particularly examining the correlations between gender, age, and facets of social anxiety. Employing a survey design, data were collected using a validated questionnaire comprising 32 items that measure key aspects of social anxiety: Fear of Negative Evaluation, Avoidance of Social Situations with Strangers, and General Avoidance of Social Situations. The study analyzed responses from 334 students, predominantly female (69.2%) and under 20 years of age (84.4%), with most participants enrolled in the Faculty of Education and Psychology (67.1%). Results indicate significant correlations between the examined factors and social anxiety levels, with p-values < 0.05 across all aspects. Gender was significantly associated with general anxiety, with females exhibiting higher anxiety levels. Age was strongly correlated with Fear of Negative Evaluation, while faculty affiliation showed a significant relationship with Fear of Negative Evaluation and General Avoidance of Social Situations, but not with overall anxiety levels. These findings highlight the critical role of gender in influencing social anxiety, while the effects of age and faculty vary across specific dimensions of anxiety.

Authors: Habsy Bakhrudin All , Wiryanto W , Omoyemiju Michael Adeniyi
Published: January 2025

Academic anxiety is characterised by the presence of internal thoughts and sentiments of fear and doubt regarding an individual's capacity to successfully complete assignments and examinations with expected results. The Cognitive Behaviour Group Counselling (CBGC) approach is an efficient method that can assist students in addressing these difficulties more effectively. When conducting this study, a quantitative technique was utilised, and a genuine experimental design was utilised. Thirty students from vocational high schools in Mojokerto, Indonesia participated in the study. The sample size was twenty-two students, and they were split evenly between two groups: an experimental group and a control group, each consisting of eleven students. A scale for measuring academic anxiety that was based on Ottens' theory was used to collect data, and it was distributed through Google Forms. A paired sample t-test analysis was utilised in order to carry out the data analysis. When the experimental group was compared to the control group, the results showed that the experimental group saw a considerable drop in degrees of academic anxiety. The results of this study suggest that CBGC is an effective method for lowering academic anxiety among students who are enrolled in vocational colleges.
Play Therapy with Ajining Dhiri Puppet Media to Improve Self-Esteem of Slow Learners

Published: January 2025

This quasi-experimental study examines the effectiveness of play therapy using the Ajining Dhiri (ADHI) puppet medium to enhance self-esteem in slow learners. Utilizing a pretest-posttest control group design, the study involved 16 slow learners with low self-esteem, as measured by the Self-Esteem Inventory by Coopersmith (1978), validated (r=0.711–0.794) and reliable (Cronbach's alpha=0.760). Participants were divided into a treatment group receiving play therapy with ADHI puppets and a control group receiving standard group counseling. Data were analyzed using the Mann-Whitney U test. Baseline findings revealed that 50% of students scored low in Strength (recognition and respect), 62.5% moderate in Significance (acceptance and affection), 75% moderate in Virtue (ethical behavior), and 87.5% low in Ability (task performance). Post-intervention results demonstrated significant improvements in self-esteem across all indicators for the treatment group. The Mann-Whitney U test yielded a value of 0.000, Z = -5.093, and a p-value < 0.05, confirming a significant difference between the treatment and control groups. The play therapy sessions, structured in three phases, enabled students to explore self-expression and cognitive engagement through puppet interactions. Compared to the control group, students in the treatment group showed greater enthusiasm and consistent self-esteem improvements. These findings validate the alternative hypothesis (H1) that play therapy using ADHI puppet media effectively enhances self-esteem in slow learners, offering a culturally contextualized and engaging intervention for addressing their psychological needs.

This study aims to identify the categories of humor employed by English teachers in the classroom. A qualitative descriptive method was used for the research. Six English class sessions were observed and recorded. The data for this study consisted of humor-containing utterances made by English teachers. The analysis classified teacher humor into two main categories: appropriate and inappropriate forms. Most of the humor used by teachers fell into the appropriate category, with the majority being related to the class material, followed by humor unrelated to the subject being taught. A small portion of inappropriate humor included self-deprecating humor, while another small portion was unintentional or unplanned. In contrast, inappropriate humor was rare and typically involved derogatory comments directed at others. These findings highlight that most of the humor used was lesson-related and aligned with pedagogical objectives, while inappropriate humor was infrequent. The results suggest that humor in the classroom is primarily used as a positive pedagogical tool, contributing to an engaging and supportive learning environment. Future research should explore the impact of different humor categories on student learning outcomes and classroom dynamics.

Published: January 2025

Background: Discharge summaries (DSs) are an important communication tool between hospital and community clinicians however errors in these documents are common. To improve the accuracy of DS information, our health network implemented a suite of quality improvement projects that promoted “More Efficient Documentation (of patient information) for Improved Care” (MEDIC).
Objective: The aim of this study was to determine if DSs post-implementation of the MEDIC program of work were associated with lower rates of medication errors.
Design: A retrospective pre- (March 2021) post- (March 2022) medical record audit was conducted at five public hospitals. Patients were included chronologically based on discharge date until the target sample size was reached (100 per group). For each patient, the DS medication list was compared to the pharmacy generated patient friendly medication list or interim medication administration chart and any discrepancies were considered errors. Utilisation of electronic Clinical Decision Support (CDS) was evaluated via review of the EMR.
Main Outcome Measure: Medication errors
Results: The mean number of DS medication errors was lower in the post-intervention group (3.0 vs 1.4, p<0.01). Fewer patients in the post-intervention group had one or more DS medication errors (59% vs 39%, p<0.01). Patients in the post-intervention group were less likely to have one or more high-risk medication errors (20% vs 10% p=0.048). There were 437 individual errors (pre=298, post=139). Omitted medications were less common in the post-intervention group (127 vs 11). Utilisation of EMR home medication CDS was higher in the post-intervention group (54% vs 69%, p=0.005). Pooled data from both groups showed completion of discharge medication reconciliation CDS was associated with a lower number of errors on DSs (mean: 3.7 vs 1.4, p<0.001, DS with one or more errors: 68% vs 39%, p<0.001).
Conclusion: The MEDIC program of work was associated with improved DS medication list accuracy.

Abstract—Centella asiatica, containing asiatic acid (AsA), represents one such candidate demonstrating promising anticancer effects. This study aims to comprehensively review the anticancer activity of AsA in published in vitro and in vivo studies. A systematic review method was employed and several databases, including Scopus, PubMed, ScienceDirect, and Google Scholar, were used to conduct a comprehensive and systematic search of the literature based in vitro and in vivo studies in November 2023 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Thirty-three articles were included, distributed across twenty-five in vitro studies, three in vivo studies, and five both in vitro and in vivo studies. Based on the findings in the reviewed articles, we report that AsA, a triterpene derived from C. asiatica, exhibits anticancer effects demonstrated both in various cancer cell lines and in cancer cell-induced animal model, through several mechanisms, including anti-inflammatory effects, antioxidant effects, inhibition of cell proliferation, inhibition of invasion and migration, and induction of apoptosis and autophagy. Conclusions based on findings in in vitro and in vivo studies, AsA has strong potential to be used and developed as an inhibitor of various types of cancer cells.

The present study focuses on improving Cognitive Radio Networks (CRNs) based on applying machine learning to spectrum sensing in remote learning scenarios. Remote education requires connection dependability and continuity that can be affected by the scarcity of the amount of usable spectrum and suboptimal spectrum usage. The solution for the proposed problem utilizes deep learning approaches, namely CNN and LSTM networks, to enhance the spectrum detection probability (92% detection accuracy) and consequently reduce the number of false alarms (5% false alarm rate) to maximize spectrum utilization efficiency. By developing the cooperative spectrum sensing where many users share their data, the system makes detection more reliable and energy-saving (achieving 92% energy efficiency) which is crucial for sustaining stable connections in educational scenarios. This approach addresses critical challenges in remote education by ensuring scalability across diverse network conditions and maintaining performance on resource-constrained devices like tablets and IoT sensors. Combining CRNs with new technologies like IoT and 5G improves their capabilities and allows these networks to meet the constantly changing loads of distant educational systems. This approach presents another prospect to spectrum management dilemmas in that education delivery needs are met optimally from any STI irrespective of the availability of resources in the locale. The results show that together with machine learning, CRNs can be considered a viable path to improving the networks’ performance in the context of remote learning and advancing the future of education in the digital environment. This work also focuses on how machine learning has enabled the enhancement of CRNs for education and provides robust solutions that can meet the increasing needs of online learning.

Published: January 2025

OBJECTIVE

To document differences in the microbiota of healthy cats versus cats with urethral obstruction (UO); compare the urinary microbiota with the oral, preputial, and rectal microbiota; and demonstrate that 16S rRNA gene sequencing will reveal rich and diverse urinary microbiota.

METHODS

15 client-owned cats with UO and 15 age-matched healthy cats were included from July 2020 through April 2021. Exclusion criteria were evidence of urinary tract infection, urolithiasis, antimicrobial administration, urinary catheterization in the past 30 days, or a comorbidity. This study was a prospective, observational study. Both groups had a baseline CBC, chemistry panel, urinalysis, urine culture, and focal bladder ultrasound. Swabs of the cystocentesis site, buccal mucosa, rectum, prepuce, and urinary samples were collected, and 16S rRNA gene sequencing was used to compare the groups and sites.

RESULTS

Differences in the microbiota richness and diversity were found in the urine of cats with UO (n = 15) compared to healthy cats (15), along with differences in the preputial and oral samples, supporting the presence of a urinary dysbiosis in cats with UO.

CONCLUSIONS

Our preliminary data demonstrates a dramatic change in the urinary microbiota of cats with UO along with changes in microbiota in other sites compared to healthy cats.

CLINICAL RELEVANCE

A urinary dysbiosis in cats with UO has been minimally supported in prior studies using 16S rRNA gene sequencing. Although these are preliminary results, documenting this dysbiosis in cats with UO provides a potential avenue for novel therapeutics.
