Published: January 2025

BACKGROUND

The worldwide rise in the prevalence of noncommunicable diseases has increased the recognition of the need to identify modifiable risk factors for preventing and managing these diseases. The office worker, as a representative group of physically inactive workers, is exposed to risk factors for metabolic syndrome, which is a primary driver of noncommunicable diseases. The use of virtual reality (VR) exergames may offer a potential solution to the problem of increasing noncommunicable disease prevalence, as it can help individuals increase their physical activity levels while providing a more immersive experience.

OBJECTIVE

This exploratory study aims to examine the interventional efficacy of at-home immersive VR exergames on metabolic syndrome biomarkers among office workers. Additionally, it seeks to investigate the impacts of at-home immersive VR exergames on the active and sedentary behaviors of office workers.

METHODS

A 3-arm, single-blinded pilot randomized controlled trial will be conducted to examine the therapeutic effects of at-home immersive VR exergames. A total of 120 Chinese office workers, engaging in less than 150 minutes per week of moderate to vigorous intensity physical activity, will be recruited via a convenience sampling method. The participants, who will be tested over a 12-week period, will be randomly assigned to one of three groups: (1) the VR exergame intervention group, (2) the regular physical activity control group, and (3) the nonexercise control group. Throughout the 12-week trial, three categories of variables will be collected across the three groups: clinical risk factors associated with metabolic syndrome, active and sedentary behaviors, and demographics. To analyze variance among the groups, a mixed linear model will be applied to assess the efficacy of each group. Differences in metabolic syndrome clinical risk factors among all groups will be used to evaluate the effects of at-home immersive VR exergames. Changes in active and sedentary behaviors will also be used to determine the impacts of VR exergames on metabolic syndrome.

RESULTS

The ethics committee of Guangzhou University, China, approved this study on September 25, 2024. Participant recruitment will begin in early 2025 and continue for approximately 3 months. Data will be analyzed after the 12-week trial is completed, with full results expected to be presented in early 2026.

CONCLUSIONS

This study explores an emerging topic by applying an at-home immersive VR exergame intervention, potentially contributing to understanding the effects of an exergame program on metabolic syndrome risk among office workers.

How well did patients sleep? Analyzing sleep behavior using BERT-BiLSTM and finetuned GPT-2 Sentiment classification: a comparison study (Preprint)
Authors: Deng Yihan , van der Meer Julia , Tzovara Athina , Schmidt Markus , LA Bassetti Claudio , Denecke Kerstin
Published: January 2025

BACKGROUND

The diagnosis of sleep disorders presents a challenging landscape, characterized by the complex nature of their assessment and the often divergent views between objective clinical assessment and subjective patient experience. This study explores the interplay between these perspectives, focusing on the variability of individual perceptions of sleep quality and latency.

OBJECTIVE

Our primary goal is to investigate the alignment, or lack thereof, between subjective experiences and objective measures in the assessment of sleep disorders.

METHODS

To study this, we developed an aspect-based sentiment analysis method: Using large language models (Falcon 40b and Mixtral 8X7B), we are identifying entity groups of three aspects related to sleep behavior (day sleepiness, sleep quality, fatigue). From phrases referring to these aspects, we are assigning sentiment values between 0 and 1 using a BERT-BiLSTM-based approach (accuracy 78%) and a fine-tuned GPT-2 sentiment classifier (accuracy 87%).

RESULTS

The results show that our approach is able to handle the specialized language occurring in the sleep disorder domain and identify the sentiment and opinion in clinical records.

CONCLUSIONS

Our method has potential in uncovering critical insights into patient self-perception versus clinical evaluations.

Sororidad laboral: hacia una cultura de apoyo y equidad entre mujeres
Authors: Castañeda Burciaga Selene
Published: January 2025

La creciente incorporación de la mujer en diversas áreas laborales ha intensificado las dinámicas de rivalidad y competencia, exacerbando las brechas de género perpetuadas por el pensamiento patriarcal. Ante este panorama, la sororidad surge como una estrategia transformadora que fomenta la solidaridad y la alianza entre mujeres. Al establecer relaciones basadas en el reconocimiento mutuo de nuestras fortalezas y diferencias, se impulsa tanto el empoderamiento individual como colectivo. Promover la sororidad en el entorno laboral no sólo favorece la autorrealización y el éxito de las mujeres, sino que también impacta positivamente en el desempeño organizacional y en la creación de ambientes de trabajo más productivos y equitativos.
Camarón que se desecha, se pierde: la fermentación láctica como solución
Authors: Cabanillas-Bojórquez Luis Angel , Picos-Salas Manuel Adrian , Gutiérrez-Grijalva Erick Paul , Heredia José Basilio
Published: January 2025

Los residuos de camarón son una fuente importante de compuestos industriales, como la quitina. Sin embargo, a pesar de los estudios realizados, estos residuos no se aprovechan completamente. Actualmente, solo se utiliza un proceso químico para obtener quitina, pero este método no permite recuperar otros componentes valiosos como proteínas y carotenoides, y consume grandes cantidades de agua y energía. Por ello, se han explorado alternativas más eficientes. La fermentación láctica (fl) ha demostrado ser una estrategia económica y eficaz para aprovechar los residuos de camarón. Este proceso genera dos fases: una sólida y una líquida (licor), que contienen proteínas hidrolizables, minerales, ácidos grasos poliinsaturados, carotenoides y quitina. Estos productos tienen potencial para ser utilizados como fuentes de antioxidantes, antiinflamatorios, inmunomoduladores y en la formulación de alimentos. De este modo, la fl de los residuos de camarón no solo contribuye a la reducción de problemas ambientales, sino que también añade valor a los desechos de la industria pesquera.

Published: January 2025

Las orquídeas son plantas cautivadoras, tanto por su belleza como por su diversidad. Con alrededor de 30,000 a 35,000 especies distribuidas globalmente, estas plantas son conocidas por su delicadeza y necesidades específicas para crecer. Una de las claves para su reproducción es la simbiosis con hongos microscópicos, los cuales juegan un papel crucial en la germinación de sus semillas. Este proceso simbiótico no sólo beneficia a la orquídea, sino también al hongo, y se ha convertido en una herramienta fundamental para la conservación y el cultivo de orquídeas. En este artículo, exploramos cómo se lleva a cabo la germinación simbiótica, los beneficios de esta relación y su potencial para mejorar las estrategias de conservación y propagación de estas fascinantes plantas.
Brücken schlagen [Tender puentes]: Lo queer a través del multilingüismo, la ambigüedad y las contradicciones
Authors: Hoechtl Nina
Published: January 2025

A partir de fragmentos del comentario de nuestra traducción colectiva „Grenzen übersetzen, translatorisches Handeln, Brückensprachen schaffen“ [Traducir fronteras, actuar de manera traslativa, crear lenguas puente] de Borderlands/La Frontera: The New Mestiza (1987) de Gloria Anzaldúa pretendemos mostrar el impacto del comentario de traducción como forma de articulación que se declara responsable de la construcción de sentido y subjetividad en el texto traducido; y al mismo tiempo, exponer nuestras estrategias y explicar algunos de los procesos y conceptos que intervinieron en la traducción para subvertir las tendencias homogeneizadoras a partir de características centrales de los textos de Anzaldúa, que son portadores de multilingüismo, ambigüedad y contradicciones. Además, nos preguntamos hasta qué punto el uso del multilingüismo hizo que los textos de Anzaldúa se convirtieran en contribuciones tan importantes a los estudios queer —entre otros— incluso antes de que fueran introducidos en los espacios académicos.
Impacts of disturbance on ant (Hymenoptera: Formicidae) food preferences and dominance in a Mexican temperate forest
Authors: Zolá-Rodríguez Meghan I. , Cuautle Mariana , Rodríguez-Flores Marco Daniel , Castillo-Guevara Citlalli
Published: January 2025

This study examines the impact of disturbance on the food preferences and dominance of an ant community in a temperate ecosystem in Mexico. The study focused on 2 types of vegetation: native oak forest and induced grassland (disturbed vegetation). Observations were conducted to record the food elements carried by ants to their nests. These data were analyzed using x2 tests. Tuna and honey baits were placed near the nests to record the presence of ants in 5-minute periods. We used a binomial model to determine whether the  probability of finding an ant foraging at the baits was affected by vegetation type, bait type, and/or ant species. Additional baits were used to determine the ant dominance indices. T-tests and ANOVAs were used to compare dominance indices between vegetation types, baits, and ant species. No significant differences were observed in food preferences between vegetations. However, some species showed a preference for honey (i.e., carbohydrates), which could be limited in ground-level environments. Ants showed a submissive behavior in both vegetation types. This research shows that ants could optimize their nutrient intake, enabling them to survive efficiently even when facing disturbances, instead of increasing dominance.

Diagnosis of Acute Diseases in Villages and Smaller Towns using AI
Authors: Kanta Thota Hari Mani , Reddy A. Veera Vardhan , Reddy K. Santhosh , N Uma , Rahman Riyazulla
Published: January 2025

Abstract: The timely diagnosis of acute diseases in rural and small-town settings remains a significant challenge due to limited
healthcare infrastructure, scarce diagnostic tools, and insufficient access to skilled medical professionals. This paper explores
the potential of Artificial Intelligence (AI) as a transformative solution for bridging these gaps. By leveraging machine learning
models trained on diverse clinical datasets, AI systems can facilitate the rapid identification of acute diseases such as respiratory
infections, diarrheal diseases, and vector-borne illnesses. These systems utilize data from accessible inputs like smartphone
applications, wearable devices, and basic diagnostic tools to provide real-time, low-cost, and accurate assessments. Additionally,
AI- powered diagnostic platforms can integrate with telemedicine networks to ensure seamless referral to medical experts when
necessary. This approach not only empowers community health workers but also enhances early detection, treatment outcomes,
and epidemic management in underserved regions. The study concludes with an analysis of the challenges, including data
privacy, model bias, and user education, while highlighting the potential for AI to revolutionize healthcare delivery in rural and
small-town contexts.
Sparse Blossom: correcting a million errors per core second with minimum-weight matching
Authors: Higgott Oscar , Gidney Craig
Published: January 2025

In this work, we introduce a fast implementation of the minimum-weight perfect matching (MWPM) decoder, the most widely used decoder for several important families of quantum error correcting codes, including surface codes. Our algorithm, which we call sparse blossom, is a variant of the blossom algorithm which directly solves the decoding problem relevant to quantum error correction. Sparse blossom avoids the need for all-to-all Dijkstra searches, common amongst MWPM decoder implementations. For 0.1% circuit-level depolarising noise, sparse blossom processes syndrome data in both X and Z bases of distance-17 surface code circuits in less than one microsecond per round of syndrome extraction on a single core, which matches the rate at which syndrome data is generated by superconducting quantum computers. Our implementation is open-source, and has been released in version 2 of the PyMatching library.
Vārdi labība un padoms 16. un 17. gadsimta tekstos un „Latviešu valodas vēsturiskajā vārdnīcā“

Rakstā aplūkotas leksēmas labība un padoms un to lietojums 16. un 17. gadsimta latviešu rakstu avotos. Lai gan vārdam labība 17. gadsimtā latviešu valodā ir jau nostabilizējusies konkrēta nozīme ‘labība, graudi’, dažos rakstu avotos tas tiek lietots ar nozīmi ‘labumi, manta’. Šāds lietojums parādās Georga Manceļa darbos konkrētā kontekstā – Lūkas evaņģēlija 1. nodaļas 53. pantā. Domājams, ka G. Mancelis šo vārdu pārņēmis no agrāka teksta, iespējams, no 1615. gada Vidzemes luterāņu dziesmugrāmatas. Iespējams, ka šādu lietojumu ietekmējis vācu vārds Güter, Gütern attiecīgajā tekstā. E. Glika Bībeles tulkojumā un citos 17. gadsimta beigu avotos aplūkotajā Lūkas evaņģēlija tekstā lietots vārds labums, mūsdienu tulkojumos – labumi. Tomēr šāds vārda labība ‘labumi’ lietojums ir fragmentārs, lielākoties vārds 17. gadsimtā lietots ar nozīmi ‘labība, graudi’ vai arī plašākā nozīmē kā ‘pārtika, raža, maize’.
Savukārt 16. gadsimta beigu avotos minētajā Lūkas evaņģēlija pantā lietots vārds padoms, kuram senajos rakstos ir vairākas nozīmes, kas tekstos tiek lietotas paralēli. Vārds padoms sastopams ar nozīmi ‘manta, bagātība, labumi, īpašums’, ‘ieteikums, kā rīkoties’ (kas ir mūsdienās zināmākā nozīme), kā arī ‘nodoms, nolūks; lēmums, spriedums’ un ‘prāts, spriestspēja, gudrība’. Domājams, ka vārda padoms lietojumu paralēli vairākās nozīmēs ietekmējis vācu vārds Rat ‘padoms’, kuram senajos reliģiskajos tekstos vācu valodā sastopamas arī vairākas citas nozīmes.
Adaptive Hybrid Verbs in Lithuanian Slang and the Problem of Morphological Decomposition
Authors: Kudirka Robertas
Published: January 2025

The article focuses on adaptive hybrid verbs in Lithuanian slang which take the suffix -inti. Extracted from the Dictionary of Lithuanian Slang and Non-Standard Language, these verbs (96 originating in the Russian language and 46 borrowed from English) are distinguished from hybrid derivatives. The study shows that affixal adaptation is used in order to incorporate borrowed verbs into the Lithuanian linguistic system. Loan verbs adapted purely phonetically are rare in Lithuanian slang and tend to be used adverbially. Although semantically, borrowing can result in new meanings, many of these verbs are seen only as trendy non-standard variants. Some of the suffix -inti verbs are morphologically decomposable: they are derived from base words already adapted in the Lithuanian language. A small number of morphologically unanalysable verbs are also investigated. These loanwords are adapted using the derivative suffix -inti and following the principles of derivative analogy. Morphological adaptation of hybrids is achieved by replacing the derivative suffix of the donor language with the suffix of the recipient language.
Par Latvijas vāciskajiem un latviskajiem muižu vārdiem. Tulkojuma aspekts

Raksts ir veltīts Latvijas vietvārdiem vācu un latviešu valodā, to savstarpējām atbilsmēm, īpaši pievēršoties tulkojuma aspektam. Seno muižu vārdu izpēte ir aktuāla arī no mūsdienu viedokļa, jo tie ir pamatā lielai daļai Latvijas ciemu (bieži tieši pagastu centru), kā arī dažu pilsētu nosaukumiem.Senākie sistemātiskie vietvārdu apkopojumi latviešu valodā ir četrās 17. un 18. gadsimta vārdnīcās (Mancelius 1638; Langius 1685; Lange 1773; Lange 1777; Stender 1789). Rakstā analizēti Kurzemes un Zemgales vietvārdi, kopumā 155 vietvārdu pāri. Vietvārdu skaits vārdnīcās ir stipri atšķirīgs: Mancelim – 41, Langijam – 21, Langem – 67, bet Stenderam jau 140 vietvārdi. Tulkojumi veido apmēram 10–13% no analizētajos avotos ietvertajiem vietvārdiem. Kopumā tika apzināti 19 tulkotie vietvārdi. Tajos parādās gan abu valodu kopvalodas vārdi, gan dialektālā leksika. Latviešu valodā tās ir mazāk un tā saistīta ar attiecīgajā vietā runāto izloksni, savukārt vācu vietvārdos atrodamas gan viduslejasvācu, gan baltvācu valodas ietekmes, kas reizēm nav nošķiramas.
Situational analytics and situation analysis centers in public administration
Authors:   Russian Presidential Academy of National Economy and Public Administration, Ponkin Igor
Published: January 2025

The article continues the author’s series on applied analytics in public administration and law. Due to
the objectively determined complexity of the subject-object areas of state regulation and public administration,
as well as the resulting complexity of state regulation and administration itself, the author argues for the
necessity of using situational analytics and situation centers in public administration. The paper presents the
author’s concept for explaining the technology to achieve predictive situational awareness through describing
a sequence of complex active cognitive actions: 1) visualization of the future; 2) scenarios of the future;
3) predictive situational-scenario modeling and predictive-projective representation of the future events in
their diverse possible variations. The study provides a detailed description of the positions that represent the
functional-target load of a situation analysis center. The author presents the theoretical basis for understanding
and interpreting the theories of distributed cognition, distributed situational awareness, and distributed
situation centers and shows their significance. The research is based on applying the research methods of
analysis and synthesis, induction, deduction and abduction, generalization, classification and modeling,
approximation, and formalization. After conducting the research, the author was able to uncover the meaning
and fundamental descriptive qualities of situation analytics and evaluate its potential.
Geo-economic factors of energy development in the Far East in the context of national and global trends
Authors:   Moscow Power Engineering Institute, Buchnev Alexander , Buchnev Oleg ,   Moscow Power Engineering Institute
Published: January 2025

Identifying and assessing the main geo-economic factors in the development of the Far East and,
specifically, the stable growth of its energy sector is of fundamental importance today. Within the context of
national and global trends, the importance of this region for the Russian Federation, both in economic terms
and in strategic development, is significant. Implementing technological and organizational innovations in the
Far East’s energy sector will positively impact the economy if renewable and non-renewable energy resources
are used in a balanced manner. This will guarantee additional solutions to several issues typical of the Russian
Far East, as well as boost economic growth in the region and positively affect the export component, which
ought to satisfy ESG standards considering its emphasis on several friendly countries in the Asia-Pacific area.
Therefore, the article focuses on the established and emerging ESG philosophy and its corresponding
investment framework in such countries as the People’s Republic of China, India, and several others. Within the
framework of national and international solutions, the author suggests practical advice on encouraging and
implementing a range of solutions aimed at growth of energy reliability, local economy, and environmental
safety in the Far East region. Furthermore, the article assesses the prospects of the energy sector’s impact on
the socio-economic sphere of the region and approaches to attracting additional investments.
Legal data: ontology of the syndicated loan agreement
Authors:   Russian Presidential Academy of National Economy and Public Administration, Mavlekeev Ilsur
Published: January 2025

The article defines legal data and its predetermination as data whose transmission and processing
have legal implications. The author discusses the correlation between natural and formal legal language.
Formalization is a crucial process for converting primary legal information into legal data. Document
language is not the best format for storing legal data because it lacks formal rigor and allows for
interpretation. In addition to classifying legal data, the article provides an example of analyzing several
different kinds of legal data. Using complex contracts as an example, the author discusses the thoughts on
the future of machine-readable legislation. To fully realize the concept of machine-readable law, it will be
possible to present a contract not as a text interpreted by lawyers but as a system of interconnected legal
data with a specific structure. At the beginning, this will be demonstrated through the example of private
agreements based on a civil law contract between professional market participants. Formalization will
continue to be a crucial component of automated law enforcement as long as civil law uses natural
language text as the primary source of the subjects of the law’s will. Civics will have to overcome its reliance
on text in favor of alternative forms of treaty representation.
Methods for assessing the sustainability of the territory
Authors:   Russian Presidential Academy of National Economy and Public Administration, Filatova Olga
Published: January 2025

Identifying the weaknesses of the object of management is a useful analytical instrument for
solving public administration problems. The foundation of such an instrument ought to be a set of indicators
that represent the ideal condition of the management system. This article outlines the primary prerequisites
for the indicators that make up this type of analytical instrument and offers three categories of indices for
assessing the region’s sustainability: indicators of social and economic development and the indicators of
ecological state. The grouping of the indicators is predicated on the notion that the region is sustainable
when its social, economic, and environmental aspects coexist harmoniously. According to the suggested
parameters, it is proposed to evaluate and consider the degree of development of the management system
independently, in addition to characterizing the indicators for each of them. The use of these indicators
involves both expert assessments of the selected parameters and the application of statistical data. The
suggested assessment system can enhance public administration’s analytical capabilities, facilitate strategic
decision-making for the territory’s sustainable development, and provide a thorough understanding of the
sustainability status of the region.
Limits on the explicit prohibition of transactions involving digital currencies
Authors:   The Central Bank of the Russian Federation, Iontsev Mikhail
Published: January 2025

The paper discusses the peculiarities of adopting Part 5 of Article 14 of the Law on Digital
Financial Assets, which prohibits digital currency transactions. The author defines payment as a form of
counter-provision and examines the idea of counter-provision concerning the theory of synallagmatic
relations. The article clarifies the definition of terms «payment» and «means of payment» and highlights
how they impact the boundaries of the ban on transactions involving virtual currencies. The article
discusses the nature of digital currencies and their place in the system of civil law objects, emphasizing
that the legal phenomenon of cryptocurrency has not yet been sufficiently researched, and the judicial
practice is formed along the lines of recognizing digital currencies as an absolute property right sui
generis. The study identifies the variety of people and digital currency types that can be dealt with in
digital currency transactions. The author considers the most intriguing aspect of digital currencies to be
their ability to completely change the established concept of money and its circulation.

Published: January 2025

Efforts to increase sales of car/motorcycle polish products have been carried out by the Graphene Guard business incubator. This product is a downstream research result of lecturer/researcher at the Faculty of Engineering, Riau University. As a new product and not yet known to the public, special strategies are needed to increase sales. In the initial stage, an online and offline sales strategy was carried out, but apparently it did not show encouraging results even though promotions had been carried out. It was felt that a reseller strategy needed to be implemented. The reseller strategy, especially offline resellers, was addressed to the students at Riau University with attractive prices and bonuses. This strategy generated significant sales in a relatively short time. The phenomenon where offline reseller sales results were very different from conventional sales strategies reflecting the changes in consumer behavior and increasingly complex market dynamics. Reseller marketing strategies, especially when carried out by individuals or small groups, often conveyed a strong sense of personalization and trust. In this strategy, focus was given to product advantages, customer testimonials, and real interactions. This created high levels of trust in consumers, and allowed them to feel confident in purchasing the product. This strategy can be a valuable experience for marketing of new products.
Propuesta colaborativa evaluativa entre dos  cátedras de la carrera de Educación Parvularia en Chile para el desarrollo de competencias académicas y profesionales utilizando una evaluación alternativa
Authors: Contreras Paredes Norton , Castro Cammouseight Michelle
Published: January 2025

La sistematización presentada da cuenta de una instancia de evaluación aplicada entre dos cátedras de la carrera de Educación Parvularia de una universidad chilena. El objetivo fue evaluar la aplicación de una experiencia evaluativa alternativa basada en competencias en formato de conversatorio. Las características del grupo muestral fueron 32 estudiantes de la carrera de Educación Parvularia de una institución privada de Educación Superior de Santiago de Chile que cursaban simultáneamente las cátedras de Neuroeducación y Psicología del Desarrollo. Su elección fue una muestra por conveniencia no probabilística, ya que, dadas las condiciones, los investigadores tuvieron facilidad de acceso a los sujetos participantes. Un grupo de estudiantes debía exponer oralmente un tema vinculado a ambas cátedras y, posteriormente, realizar comentarios y preguntas frente a otro tema diferente presentado por otro grupo. La instancia se evaluó mediante un instrumento tipo rúbrica (a nivel de forma y contenido) con una exigencia del 70% en la escala chilena de calificaciones. Se encontró que las estudiantes tuvieron un 67% de logro del indicador de aprendizaje vinculados a elementos de forma y un 100% de logro de los indicadores de aprendizaje vinculados a elementos de contenido. Así, se propone la necesidad de generar más y mejores instancias de evaluación que sean diferentes a la evaluación escrita tradicional en la educación superior, fortaleciendo un currículum orientado a competencias y enfocado a un adecuado desempeño profesional y laboral.

Published: January 2025

La pandemia por Covid-19 vino a interponer la necesidad de incorporar plataformas digitales en los procesos de enseñanza y aprendizaje para dar continuidad a la formación académica. A partir de esta realidad, en la Universidad Estatal a Distancia de Costa Rica se optó por una modalidad en línea que ayudara a enfrentar la nueva realidad. Este proceso ha planteado el reto en el profesorado de repensar las estrategias didácticas desde los entornos virtuales de aprendizaje, alineadas con el modelo pedagógico de la universidad y la educación a distancia. Ante esto, se propuso una investigación bajo un enfoque cualitativo y un diseño fenomenológico, para analizar cómo el profesorado de la Cátedra de Desarrollo de la Niñez en Edad Preescolar ha logrado un acercamiento con las metodologías activas en su práctica pedagógica y mediática. Los resultados evidenciaron la existencia de un acercamiento a metodologías activas como el aprendizaje basado en proyectos y en problemas, el estudio de caso y el aprendizaje cooperativo por medio de las estrategias didácticas implementadas en esta cátedra. No obstante, es necesario promover espacios de capacitación relacionados con esta temática con el objetivo de subsanar algunos vacíos en cuanto a la planificación, aplicación y evaluación de estas metodologías en los entornos virtuales de aprendizaje.
Sustainable human resource practices in Indonesian family-owned listed companies.
Authors: Suhardjo Iwan , Suparman Meiliana
Published: January 2025

Given Indonesian family-owned companies’ significant economic role contribution and the increasing emphasis on sustainability, understanding sustainable human resource practices is crucial. This study investigates how leading Indonesian family-owned listed companies integrate these practices into their sustainability strategies and performance and compares their approaches with non-family-owned companies. Using a stakeholder theory lens and ethical sustainability governance framework, analyzing their sustainability reports, and comparing them with non-family-owned companies, we aim to understand the unique role of family control and governance in shaping sustainable human resource practices in Indonesia. Our findings suggest that while family-owned companies acknowledge the importance of sustainable human resource practices, their approach is driven by external regulatory pressures, resulting in limited measures for employee engagement and training. This indicates a lack of integration between dynamic capabilities and a change behavior approach to sustainability as proposed by Suhardjo et al. (2024a). Non-family-owned companies, on the other hand, tend to adopt a more systematic approach, prioritizing training and conducting regular employee surveys. This study extends the previous research of Gunawan and Koentjoro (2023). This study contributes to the literature on family-owned businesses and sustainable human resource practices, highlighting the need for a strategic approach to sustainable human resources in family-owned companies.

Introduction: Paget's disease of the vulva is an intraepithelial
adenocarcinoma, primarily arising from vulvar skin glands, with or without
an underlying invasive adenocarcinoma. It brings low mortality and a high
local recurrence rate and mainly affects postmenopausal women. Case
outline: This is a case report of a 57-year-old postmenopausal woman, who
had histopathological (HP) verified Extramammary Vulvar Paget's disease
(EVPD) in 2014, and underwent a radical vulvectomy with a right-sided
inguinofemoral lymphadenectomy and V-Y flap at the Oncology Institute of
Vojvodina. Nine years later, in 2023, the patient was presented with a
biopsy HP proven EVPD recurrence. The recurrence was surgically treated with
vulvectomy and bilateral fasciocutaneous V-Y flaps reconstruction. The
operative HP specimen proved the EVPD recurrence with atypical cells on one
edge of the specimen. Due to the infection-complicated healing and wound
dehiscence, the first reoperation was performed, which included wound
debridement and left-sided rotational flap. We carried out the wound care
and toileting in the postoperative course, with antibiotic treatment. Due to
infection-complicated healing, tissue necrosis and consequent dehiscence,
the second reoperation was performed, which included wound debridement with
granulation tissue excochleation and Tiersch-type skin graft. Conclusion:
The patient was discharged 21 days after the second reoperation in good
condition. A regular oncological postsurgical follow-up on the 3th and 6th
month revealed no recurrence or deterioration of the general condition or
local findings. The patient subjectively feels well and has no complaints or
unwanted effects of the applied treatment.

Background and purpose: Treatment of idiopathic scoliosis in childhood aims to prevent curve progression. It is generally accepted that curves > 50° have the highest risk of progression, but less well described is what happens with mild to moderate curves. The aim of this study was to assess long-term curve progression and health-related quality of life (HRQoL) and compare thoracic and thoracolumbar/lumbar (TL/L) curves.Methods: We identified 177 patients diagnosed with a pediatric spinal deformity and treated at our institution from 1972 through 1983. 91 of 129 eligible patients with idiopathic scoliosis completed follow-up (71%). Patient files from treatment/observation in childhood were reviewed including detailed descriptions of radiographs. At follow-up we assessed long standing full-spine radiographs and HRQoL with the Scoliosis Research Society 22 revised questionnaire.Results: Mean follow-up was 41 years (standard deviation [SD] 2.5 years). 21 patients underwent surgery in adolescence or early adulthood leaving 70 patients for analysis of curve progression, of whom 61 had complete radiographs. For patients with a main curve < 25° at the end of treatment in adolescence (n = 19) mean curve progression was 7° (SD 9); for 25–40° curves (n = 26) 16° (SD 13); for 40–50° curves (n =10) 22° (SD 8); and for curves > 50° (n = 6) 17° (SD 6). There was a linear association between main curve size at follow-up and SRS-22r subtotal score (P = 0.003).Conclusion: We found substantial curve progression for patients with main curves > 25° at end of treatment, but with a considerable variation between patients. Curve progression was not associated with curve size at the end of treatment and did not differ significantly between thoracic and TL/L curves. Larger main curve size at follow-up was associated with lower HRQoL.
VR video game-induced psi communication with red and green ganzfeld: A proof-of-principle study

In this proof-of-principle study, we intended to employ the ganzfeld psi method with two novel features. (1) We used a set of four different interactive video games randomly selected for each trial to be played in a virtual reality (VR) setting by the sender, while the receiver was wearing goggles producing either (2) a red or green ganzfeld, randomly selected. N = 48 young couples in a romantic relationship were recruited as sender-receiver pairs, resulting in 48 trials. Regarding the main confirmatory hypothesis, across all trials the experiment registered 15 hits out of 48 attempts, where the chance level lies at 12. According to a binominal test, the probability of having exactly, or more than, 15 hits (K) out of 48 trials (n) is p = .199. The receivers’ hit rates in the green as compared to the red ganzfeld were not significantly different (χ² = .814; p = .367). Assessed experiential state variables for the video game and the ganzfeld sessions as well as the measured trait variable absorption did not affect the hit rate. An analysis of participants’ responses revealed that independent of the hit rate the four games were identified as targets a strongly unequal number of times. The design of potential future studies is discussed.
Confirmatory study of anomalous experiences in enchanted spaces
Authors: Houran James , Laythe Brian , Little Cindy
Published: January 2025

This pre-registered study tested the concept of an ‘enchantment–psi loop’ via distinct immersive visits to sacred, haunted, and augmented reality environments. In particular, we specified four hypotheses based on the premise that anomalous experiences and cognitions would significantly shift by applying a Paranormal Belief × Transliminality × Enchantment formula. A vetted sample of thin-boundary participants (n = 22) organized into small tour groups completed measures of environmental features, real-time encounter experiences, enchantment levels, and a computerized test of putative psi after counterbalanced exposure to each of the three ‘enchanted’ conditions, as well as paired testing sessions within a purposely ‘disenchanted’ environment. Our hypotheses received mixed support. Consistent with predictions, participants’ scores on both encounter experiences and psi performance increased in the enchanted vs. disenchanted conditions, though situational-enchantment levels correlated positively with encounter experiences and negatively with putative psi. Participants also tended to have above-chance scores in the enchanted conditions, but many of our predicted effects did not reach statistical significance. Tangential analyses revealed that both encounter experiences and putative psi were also influenced differentially by various emotional (i. e., feelings of happiness), motivational (i. e., attentional focus), and environmental (i. e., sentimentality and presence) factors. The results lend credence to aspects of the enchantment-psi loop yet indicate the need for future research to clarify important nuances or complexities with the model that likely affect the reliability or robustness of its predictions.
Influence of Elevation on Falcataria moluccana [Miq.] Barneby & J.W. Grimes Gall Rust Incidence and Severity in Agusan del Norte, Philippines

Gall rust disease poses a significant threat to falcata (Falcataria moluccana [Miq.] Barneby & J.W. Grimes), particularly in different elevation ranges. This study aimed to assess the gall rust disease incidence and severity at low (0–200 masl), moderate (201–400 masl), and high (401–600 masl) elevations. Results showed a significant correlation between gall rust disease incidence and severity and elevation based on Spearman rho correlation analysis. Higher elevations were associated with increased gall rust disease incidence and severity. This suggests that environmental conditions specific to these elevations may aggravate gall rust development. Based on the findings, temperature and relative humidity, which vary with elevation, play a role in gall rust disease incidence. Conversely, light intensity significantly influences gall rust disease severity across elevation ranges. These findings signify the importance of elevation-related factors in disease management strategies in falcata plantations. By identifying the relationship between gall rust disease and elevation, this research provides insightful information that can be used to improve disease management strategies and create focused control measures. The results provide an in-depth understanding of gall rust disease dynamics and offer recommendations for reducing its impact.
