Published: February 2025

We conducted a survey with 728 college students in the Pearl River Delta region of China to study the relationship between career adaptability and career exploration behavior. We also evaluated whether career self-efficacy played a mediating role in this relationship and whether proactive
personality played a moderating role. The results showed that career adaptability had a significant positive predictive effect on career exploration behavior, and career self-efficacy mediated this relationship. Further, proactive personality moderated the relationships between career adaptability
and career exploration behavior, and between career self-efficacy and career exploration behavior. That is, career self-efficacy in choosing a job was an important psychological mechanism between college students’ career adaptability and career exploration behavior, and proactive personality
was an intervening factor in the relationship between career self-efficacy in choosing a job and college students’ career exploration behavior. This study introduces psychological traits such as career self-efficacy, career adaptability, and proactive personality into the study of college
students’ behavior, which not only expands the field of research, but also provides empirical support for how colleges and universities can support students to develop these psychological traits.

Authors: Wang Jiajian , Chang Biru , Abu Talib Mansor , Kang Yan
Published: February 2025

Through exploring the psychological dynamics within career development, this study investigated how subjective socioeconomic status (SSS) influences vocational outcome expectations (VOE) among university students. We hypothesized that (a) career adaptability would mediate this relationship,
enhancing the positive impact of SSS on VOE, and (b) proactive personality would moderate the relationship between career adaptability and VOE. We used established scales for measuring the main variables with a sample of 834 Chinese undergraduates. The results supported our hypotheses, with
career adaptability mediating the relationship between SSS and VOE, and proactive personality moderating the relationship between career adaptability and VOE. These findings provide valuable insights into enhancing career-development interventions, highlighting the importance of psychological
resources and personal traits in shaping career expectations. Our research offers practical implications for educational institutions to more effectively support students’ career development.

Authors: Lin Qiaoling , Li Yingxia , Li Lei , Yu Xuewen
Published: February 2025

The rise of social commerce has drawn attention from scholars and practitioners, but the role of virtual influencers (VIs) remains underexplored. Utilizing the computers as social actors paradigm, our study examined how the anthropomorphism of VIs influences consumer behavior, with
brand credibility as a moderator. We analyzed survey data from 408 consumers using partial least squares structural equation modeling. Findings showed that the anthropomorphism of VIs enhanced social presence and telepresence, boosting consumers’ purchase intention. Additionally, brand
credibility moderated the effect of telepresence on purchase intention. The study concludes with a summary of implications for research and practice.
Childhood neglect influences smartphone addiction among college students: The mediating role of self-esteem
Authors: Chen Fang
Published: February 2025

This study assessed the relationships among childhood neglect, self-esteem, and smartphone addiction in a cohort of 531 college students. Employing structural equation modeling alongside the bootstrapping technique, I discovered that childhood neglect influenced smartphone addiction
both directly and indirectly, with self-esteem acting as a mediator of this relationship. The analysis demonstrated correlations between every facet of childhood neglect and both self-esteem and smartphone addiction. Furthermore, I identified a significant association between self-esteem and
smartphone addiction. The results indicated that self-esteem served as a partial mediator in the nexus between childhood neglect and smartphone addiction, accounting for 56.34% of the overall effect. Implications of the findings are discussed.

Authors: Li Xintong , Huo Meiji
Published: February 2025

This study investigated the relationship between transformational leadership and burnout among music teachers in China, examining two mediators (harmonious passion and work vitality) and a moderator (peer support). We used a three-wave survey to collect data from 315 music teachers.
The results showed that transformational leadership had significant effects on burnout. Harmonious passion and work vitality mediated this relationship, while peer support played a moderating role. Through highlighting the central role of transformational leadership and peer support in mitigating
burnout, these findings provide useful information for music education policy making and management practices aimed at improving the working conditions and efficacy of music teachers.
AUMENTO DE SENSIBILIDADE AO REFORÇO COM REFORÇADORES CONDICIONADOS: Estudo único de caso com TEA
Authors: Pinho Otávio Corrêa , Kramm Daniele de Lima , Gonçalves Fábio Leyser
Published: February 2025

Autism Spectrum Disorder (ASD) refers to a broad range of behavioral, cognitive, motor, and social alterations. Some children with ASD exhibit restricted interests, learning difficulties, and low motivation. This case study aimed to investigate the development of sensitivity to reinforcement in a single subject who displayed low sensitivity to reinforcers in their repertoire, similarly showing little interest in complying with demands that produce conditioned and arbitrary reinforcers. The research objective was to expand the repertoire in this subject, thereby making the participant more likely to emit responses to produce arbitrary reinforcers through record-based techniques of free-operant and repertoire development. Following the intervention, we observed an average session duration of 110 minutes, expansion of reinforcers to 6 new objects, and increased learner engagement in activities.

Published: February 2025

Introduction: Psychiatric reform in Brazil aims to humanize treatment for mental health users. The Psychosocial Care Network (RAPS) came to replace asylums and offer humanized care. However, we observed setbacks due to the revolving door, in which users are repeatedly hospitalized and become chronic. Objective: We investigated the occurrence of the revolving door phenomenon in a mental health inpatient service of a university hospital in the Minas Gerais triangle. Method: Exploratory, qualitative and quantitative research analyzed the medical records of users with two or more hospitalizations in one year from 2018 to 2021. Results and discussion: We identified that the revolving door is recurrent. We characterized the socioeconomic profile of users, with the majority having 2 to 4 hospitalizations in one year, most hospitalizations were involuntary and compulsory, the prevalent diagnoses were schizophrenia and mood disorders, 56% were single, most had incomplete elementary education, young adults and men, 54% used alcohol and other drugs. The data point to the fragility of the RAPS and family support, the lack of preparation of professionals, and the tendency towards chronicity. Final considerations: The findings show the relevance of identifying the revolving door in the RAPS, which highlights the fragility of extra-hospital services in offering continuous care. The urgency of policies that strengthen deinstitutionalization and integration between health services and the community is highlighted, in order to end the asylum model and promote effective psychosocial reintegration of users.

Authors: Ortega-Portilla Paola Andrea , Escobar-Chavarría Omar , Gutiérrez-Pabello José Ángel
Published: February 2025

Una de las características distintivas de la infección por Mycobacterium bovis es la muerte celular. El tipo de muerte celular que se produce durante la infección determina la persistencia de las enfermedades micobacterianas. El objetivo de este artículo es proporcionar una revisión integral y trazar los posibles escenarios de los tipos de muerte celular en la patogénesis de la tuberculosis bovina. Con los datos actuales se puede concluir que: 1) el desarrollo de la apoptosis y sus diferentes variantes está relacionado con el control de micobacterias, 2) la autofagia es un mecanismo conservado que limita la replicación intracelular de micobacterias, 3) la piroptosis es un mecanismo extremo que ayuda a controlar M. bovis a costa de dañar el tejido del hospedero, y 4) la necrosis permitirá el escape y proliferación de micobacterias.

Published: February 2025

El análisis de redes sociales (ARS) ofrece una forma alternativa de estudiar el mercado de ganado destinado al sacrificio, permitiendo realizar mediciones con el fin de analizar tanto el origen como el destino de dichos animales. La investigación aquí descrita se propuso determinar la estructura de red del mercado interno de ganado movilizado para el sacrificio en México entre 2017 y 2021. La estructura de ese mercado se analizó utilizando medidas de localización espacial, especialización económica, de densidad de la red y especialización. Un promedio de 4.7 millones de cabezas de ganado fueron movilizadas cada año en México para su sacrificio, con 302 permisos de movilización solicitados cada día, cada uno para un promedio de 42.7 cabezas de ganado. La especialización relativa del mercado fue baja, siendo mayor para la demanda, pero no diferente de la oferta (P>0.05). El mercado se caracterizó por el comercio intraestatal, la baja densidad de la red, la baja centralidad de los insumos, la baja centralidad de los productos y los altos niveles de especialización del mercado municipal. De ahí que el mercado nacional de ganado para sacrificio tenga baja especialización, alta diversificación y homofilia.

Published: February 2025

El destete es un evento traumático para el lechón, ya que implica cambios que son responsables de alteraciones gastrointestinales, una disminución de la productividad o incluso la muerte. El desarrollo de resistencia bacteriana debido a la inclusión de dosis subterapéuticas de antibióticos en las dietas de inicio se ha convertido en un importante asunto de salud pública, prohibiendo su inclusión en la alimentación animal. El concentrado de proteína de papa (CPP) se ha considerado una alternativa para regular la inflamación y los trastornos intestinales debido a su contenido de péptidos antimicrobianos que tienen efectos beneficiosos sobre la homeostasis intestinal. En este estudio se evaluó el efecto del nivel de inclusión de CPP en una dieta libre de antibióticos sobre la concentración de marcadores inflamatorios como interleucina-12p40 (IL-12p40) y factor de necrosis tumoral alfa (TNF-α) en el tejido ileal y la concentración de ácidos grasos volátiles (AGV) en la digesta colónica. Se asignaron 90 lechones a tres tratamientos: 1, dieta basal (C) (dieta sin antibióticos ni CPP); 2, dieta basal con 6 % de CPP (CPP 6%) y 3, dieta basal con 8 % de CPP (CPP 8%). A los 15 días posdestete, se eutanasiaron seis lechones por tratamiento para la recolección de muestras. El grupo CPP 8% tuvo los niveles más altos de AGV y la concentración más baja de citocinas inflamatorias en comparación con el grupo C, que tuvo los niveles más bajos de AGV y la concentración más alta de marcadores inflamatorios. La inclusión de CPP en las dietas de inicio de lechones destetados puede ser una alternativa eficaz para regular la disbiosis intestinal durante el destete.

Social Work foundations in mental Health Care – quantitative Research
Authors: Hubkova S. , Jarmoch E. , Weiss E. , Pala G.
Published: February 2025

Aim. In the theoretical-empirical contribution, the author
presents and identifies mental health care in connection with
social work, its methods of activity and ways of implementing
the work. The author analyzed the basic conceptual definitions
that are inherent in social work in a psychiatric day hospital. She also pointed out specific work procedures of a social
worker in a psychiatric day hospital.
Methods. In quantitative research, the author uses the SQUALA self-assessment questionnaire to determine life satisfaction in people with mental problems who have completed hospitalization in a specialized outpatient psychiatric care facility.
70 respondents were approached for the research. Based on
the selection of individual partial results of the quantitative
research, the author evaluated the most important emotional
and internal values in women and men in the average age category of 43 years. The total quality of life score was given by
the sum of individual scores within 23 areas. Respondents had
the opportunity to choose an answer within the questionnaire
items, assigning importance to individual items within a range
of eight values.
Results. The main indicator of satisfaction with the level of
fulfillment in the life of a person with mental disabilities is
the discrepancy between meaning and fulfillment. The author
points out the priority areas of life down to the least important
values that occur in the lives of respondents. At the end of the
empirical part, the author evaluated the established hypothesis.
Conclusion. A person with mental disabilities must have all
basic life needs ensured, even during hospitalization or placement in any facility, in accordance with the duties and obligations of the person guaranteed by legislation. The basic element of care for a person with mental illness is efficiency,
concentration and ensuring the maintenance of social relationships. At the end of the empirical part, the author also points
out the extensiveness of the research carried out, and it would
be encouraging to expand the research based on the SQUALA
questionnaire to include further investigations using the WHOQOL-BREF and WHOQOL-100 quality of life questionnaires.

Authors: Majda M. , Gaziova M. , Suchter J. , Petro M. , Pavlikova M.
Published: February 2025

The main objective of this theoretical-empirical study that analyzes two types of care for problematic children in professional
families is to point out and identify the specific requirements
and issues of caring for children who, for various subjective
or objective reasons, experience problematic life situations.
Methods. In the present research, the authors investigated
the satisfaction of professional parents in providing care for
children with ordered institutional care by use of qualitative
techniques. The main identifiers and categories in determining
satisfaction were the performance of their profession, dissatisfaction of professional parents in cooperation with the professional team in the center for children and families, identifying
the most common causes of dissatisfaction of professional parents in caring for minor children and finding a correlation between the perception of their profession as a positive contribution to the further development of the child. Eight participants,
women who are employed in the center for children and families, participated in the research. In the final part, we verify the
established hypotheses that identify the issues of professional
families. Conclusions and discussion. The main contribution
of the final part is the awareness of the sensitivity of the topic
identified by the created interview with the participants. When
confirming the four established hypotheses, we can say that
three of them were confirmed, while the hypothesis that stated
the dissatisfaction of professional parents in cooperation with
other professional teams was not confirmed. Conclusion. The
study points to the sufficient satisfaction of professional parents
in the performance of their profession, identifies the most common causes of dissatisfaction of professional parents in caring
for minor children and, last but not least, it is a pleasing fact
that professional parents perceive their profession as a positive
benefit for the child in terms of his further psychological development. Professional parents have especially good cooperation
with other experts who are interested in the well-being of the
child in the professional family, and so we can say that it is the
professional family that becomes a refuge for the child, but
also a springboard for his future life in society

The introduction of lithium (Li) in AlSi7Mg alloys has significant implications for their mechanical properties and phase composition. This study investigates the effect of lithium on the phases present in an AlSi7MgLi alloy with the chemical composition of 7% Silicon, 0.36% Magnesium, and 0.80 Lithium using Thermo-Calc software with calphad methodology. Thermo-Calc, a powerful computational tool for thermodynamic and phase equilibrium analysis, allows for precise simulation of microstructural evolution and phase transformations. This research provides a detailed thermodynamic assessment of the specified alloy composition, focusing on the stability and distribution of phases such as primary silicon, magnesium silicide, and lithium-containing phases. The objective is to understand how lithium affects the phase behaviour and properties of the alloy, guiding the development of optimized compositions for enhanced performance. The results from Thermo-Calc simulations will be compared with available empirical and theoretical data to validate the predictions. This study highlights the importance of computational tools in advancing materials science, enabling precise phase predictions and offering insights into the role of lithium in aluminium alloys.

Published: February 2025

Este trabalho tem como objetivo realizar uma revisão literária sobre as práticas de cuidados de saúde sexual na comunidade LGBTQIA+, destacando os principais desafios e oportunidades para melhorar o acesso e a qualidade do atendimento prestado a essa população. A pesquisa foi realizada utilizando a estratégia PICO, abrangendo artigos publicados entre 2019 e 2024, que abordam a saúde sexual da comunidade LGBTQIA+. Os resultados apontam para a necessidade urgente de capacitação contínua dos profissionais de saúde, desenvolvimento de políticas públicas inclusivas e criação de práticas baseadas em evidências que respeitem a diversidade sexual e de gênero. Embora algumas iniciativas, como a profilaxia pré-exposição (PrEP), tenham demonstrado avanços, a discriminação e o estigma ainda representam grandes barreiras. Para futuros estudos, é crucial que mais pesquisas com amostras representativas e instrumentos validados sejam realizadas, além da implementação de políticas de saúde que garantam equidade no atendimento.
Moralischer Kontraktualismus und das Nichtidentitätsproblem
Authors: Martin Desa Valeska
Published: February 2025

Der moralische Kontraktualismus scheint als Konzeption einer nicht-konsequentialistischen intergenerationellen Ethik sehr vielversprechend. Eine zentrale theoretische Herausforderung stellt jedoch das Nichtidentitätsproblem dar. Spezifisch ist zu klären, ob zukünftige Personen einen Einwand gegen die Prinzipien unseres Handelns haben, wenn unser Handeln negative Folgen für die Lebensqualität zukünftiger Personen hat, die Existenz der konkreten Personen aber von ebendiesem Handeln abhängt und ihr Leben für sie insgesamt lebenswert ist. Eine prominente Antwort besteht darin, die Einwände zukünftiger Personen “nicht-komparativ” zu verstehen. Ihr Einwand bestehe also nicht darin, dass sie durch unser Handeln schlechter gestellt werden, als sie es andernfalls wären, sondern darin, dass sie dadurch in relevanter Form schlecht dastehen. Es ist bislang unklar, wie genau eine solche Position im Rahmen des moralischen Kontraktualismus aussehen könnte, ob sie eine Lösung des Nichtidentitätsproblems darstellt und ob ihre substanziellen Implikationen überzeugen. Dieser Beitrag prüft daher kritisch die Möglichkeiten und Grenzen eines nicht-komparativen kontraktualistischen Ansatzes. Es wird dafür argumentiert, dass nicht-komparative Einwände mit Bezug auf das Wohlergehen der zukünftigen Personen nicht plausibel sind, solange ihr Leben nicht überwiegend schlecht für sie ist. Der hier diskutierte Ansatz kann für den moralischen Kontraktualismus also höchstens eine Teilantwort auf das Nichtidentitätsproblem darstellen.

Published: February 2025

Objectives: The aim of this study is to examine the association between diabetic ketoacidosis (DKA) at type 1 diabetes diagnosis and long-term glycemic outcomes, insulin requirements, BMI SDS and diabetes technology uptake in youth. Research design and methods: Data from nine countries (Austria, Czechia, Germany, Italy, Luxembourg, New Zealand, Slovenia, Switzerland and USA (Colorado)) including youth (0.5-15.9 years) diagnosed with type 1 diabetes in 2019-2020 and followed for 2 years thereafter. Participants were divided into three groups: no DKA, non-severe, and severe DKA at diagnosis. HbA1c, insulin requirements, BMI SDS, and use of technology, including automated insulin delivery (AID), were assessed. Results: A total of 9,269 individuals (54.8% males, mean age 9.0 years) were included in the analysis. DKA at diagnosis was observed in 34.2% of participants and severe DKA in 12.8%. After one year, adjusted mean HbA1c was higher in the severe DKA group (7.41%) compared to non-severe DKA (7.23%, p=0.001) and no DKA groups (7.14, p<0.001), and this difference persisted after two years (7.58% vs. 7.38%, p<0.001, and vs 7.32%, p<0.001). Higher BMI SDS was observed in both DKA groups compared to no DKA. The use of AID was associated with lower HbA1c levels compared to other treatment modalities and moderated differences between DKA groups after two years of follow up (p=0.072). Conclusions: Both severe and non-severe DKA at type 1 diabetes diagnosis were associated with persistently higher HbA1c and higher BMI SDS. AID use diminishes the association of DKA at diagnosis and higher HbA1c over time.
Barriers to Culturally Sensitive Care for Muslim Families: Healthcare Providers' and Social Work Perspectives on the Role of Islamic Faith in Parental End-of-Life Decision-Making for Children
Authors:   , Nabag Eiman I.
Published: February 2025

In this study, the impact of Islamic culture and religious teaching on parents is studied with regard to their ability to care for children who are living with life-threatening illnesses, receiving palliative care, and approaching the end of their lives. Health care providers, prequalified social work students, and Muslim community leaders are also interviewed about their engagement and the support and care they provide Muslims with children suffering from terminal illness and facing imminent death. This study also examines some of the strategies and guidelines used in England and Wales to help shape palliative care services and end-of-life care for children. Specifically, the policy analysis was intended to critically examine health policies concerning children who are at the end of their lives, especially in regard to their culture and religion. Methodology: In this qualitative study, semi-structured interviews were conducted with healthcare professionals, a mosque leader, and prequalified students. As for the parent participating in the study, a narrative interview was conducted to allow her to talk freely (Fox, 2009). Findings and conclusion: Although both culture and religion have an impact on families' experiences at the end of a child's life, some cultural values can help families cope with the difficult process of caring for a dying child. The study concluded that culturally sensitive care requires diversity in the workforce, trusting and knowledgeable community members, and interactions between Muslim communities and healthcare organizations.
Disentangling the Effects of Nitrogen Dioxide and Particulates in Air Pollution on Human Health: A Mechanistic Toxicological Approach
Authors:   , Bateman Joshua W. P.
Published: February 2025

The ambient levels of particulate matter (PM) and nitrogen dioxide (NO2), two major pollutants within both outdoor and indoor air, are typically proportional given that they are often emitted from the same sources, such as motor vehicles and industry. Epidemiological studies have linked inhalation exposure of each pollutant to adverse pulmonary health effects, although difficulty lies in distinguishing the pollutant-specific effects due to their co-emission. These health effects could be determined by assessing either pollutant type within the same experimental system. To address this research gap, an in vitro co-culture model of the alveolar barrier comprising alveolar type 1 cells (hAELVi), alveolar type 2 cells (NCI-H441) and alveolar macrophages (differentiated THP-1) was characterised. Through culturing at the air-liquid interface, the co-culture was examined after pollutant co-exposures to PM (aerosol exposure) and NO2 (using a novel NO2 exposure unit). Standardised PM samples of carbon black, urban dust, indoor dust, as well as freshly captured diesel emission particles were chosen based on their relevance to human exposure. The ability of each pollutant to affect cytotoxicity, barrier function, pro-inflammatory responses, oxidative stress, and the transcriptome (via RNA sequencing) was evaluated. The results showed that both PM and NO2 can act in a pro-inflammatory manner, shown through IL6 and IL8 release (via ELISA). In contrast, confocal microscopy revealed that NO2 induced morphological changes, which could be indicative of phenotypic alterations, especially in NCI-H441 cells. Co-exposure of PM samples with NO2 was shown to amplify PM-induced cytotoxicity and the pro-inflammatory response. RNA-sequencing uncovered a potential synergistic mechanism behind this effect, where NO2 inhibits anti-inflammatory mechanisms, allowing PM to induce an augmented pro-inflammatory response. In conclusion, this work suggests that differing constituents of air pollution may be able to act synergistically to amplify airway inflammation. However, this was shown to be dependent upon the source of the PM. These results highlight the importance of considering the toxicological effects of air pollution both independently and in relation to each other, an important factor when considering the reduction of air pollution exposure to improve the burden upon public health.

Carbon dioxide is increasingly used as a refrigerant in modern refrigeration systems, especially in supermarkets and industrial cascade installations, where the efficiency of these systems at low temperatures represents a significant advantage. Innovations in this field highlight the sustainability of refrigeration systems that use CO2, effectively addressing various challenges arising from its (primarily poor thermodynamic) properties compared to conventional synthetic and other natural refrigerants. Controlling the high pressure in the gas cooler is the confirmed method for improving the operation of the CO2system in the transcritical region. Maintaining it at an optimal value achieves greater system efficiency and savings. This paper presents a single-stage transcritical CO2 system based on the as-built technical solution implemented in the Laboratory for Thermal Science at the Faculty of Mechanical Engineering, University of Belgrade. A thermodynamic analysis of the influence of various parameters on the optimal pressure and the coefficient of performance was carried out. Among these parameters, particular focus was given to the effect of the compressor’s isentropic efficiency, utilizing existing equations from the available literature and an equation derived from the analysis.

The framework for EU energy and climate policy foresees Europe’s energy system becoming decentralised, decarbonised and community led. Also, there is an increasing demand for energy-efficient solutions and intelligent systems in buildings that cannot only enhance comfort and convenience, but also reduce energy consumption and the environmental impact. The ambitious plans for increasing the share of renewable energy sources and improving energy efficiency in buildings require continuous improvement in policy and research for new and efficient implementation approaches and instruments. Improvements in building efficiency, regarding energy and other resources, require a systematic approach that goes beyond the current common practice of energy-consumption monitoring and optimization. One of the innovative solutions that can help in the sustainable transformation of the EU building stock is the Smart Readiness Indicator (SRI), introduced by the European Union in 2018 while amending the Energy Performance of Buildings Directive. This paper presents practical elements of the SRI auditing with the emphasis on identification of energy flexibility in three different buildings in Slovenia and Croatia. Obtained results are clearly indicating that the SRI can become an important tool for the transition to a more energy-efficient and sustainable built environment. It encourages a shift from traditional, one-dimensional, consumption-based energy buildings (consumers) towards more flexible, demand-response buildings that produce energy and consider the intermittent nature of renewable energy sources (prosumers). Also, based on the experiences derived from the initial testing of SRI in Slovenia and Croatia, the key competences of SRI auditors have been identified. The paper's conclusion objectively presents the challenges of future implementation of SRI in Slovenia and Croatia.

The energy refurbishment process involves an initial data collection which is mandatory during the building diagnostics phase. In this paper we address the building construction and materials, technical parameters, building location and form. The main goal is to set up a framework through examples of data collection methods for holistic energy refurbishment. The subjects of this study are two social housing buildings which belong to the 8th district Municipality in Budapest, consisting of 109 and 100 individual dwellings. On-site data was collected and building material samples were tested in the laboratory. The testing included measurements of the overall thermal transmittance of walls and heat transfer coefficient of a brick. The monitoring was conducted during a 72-hour period on-site using a heat flow meter. The research discusses the measurement process and laboratory testing results to formulate further steps and milestones during the energy renovation process of these specific and similar buildings.

The research elaborates the overall design and construction process of the Helloparks PT2 warehouse and distribution center building located in Páty, Hungary. The goal of the project was to achieve energy and carbon neutral results and to apply for international BREEAM green building certification, which recognizes outstanding performance of buildings and sustainability in the built environment. From the conceptual phase of the project the investors decision was to use innovative building performance simulation technology to assess and enhance the performance of the project in the following categories: energy performance, operational performance, carbon footprint, LCA, thermal comfort, passive design analysis, heat transfer analysis etc. The results justify the significance of adequate decision making during the design-phase of the project to enhance its environmental performance, human health and comfort by reaching annual zero operational energy and carbon emissions, which is reached with low zero carbon technologies and integrated solar photovoltaic systems.
“I am not really sure how to explain”: Marketing Augmented Reality Experiences to New Audiences
Authors: Freeman Matthew
Published: February 2025

If the immersive sector is to fully move beyond engaging the early technology adoptors and is to capture mass audiences from different corners of the cultural landscape, then gateway promotional content must be developed – that is, marketing that engages those new to immersive technologies. How, though, can the magic of 3D worlds be communicated via 2D media? Addressing this current industry challenge, the Immersive Promotion Design team was funded by StoryFutures Academy in 2020 to identify new promotional strategies for how virtual and augmented reality experiences can be better marketed to today’s audiences. This article outlines our approach to applying research into new ways of marketing VR/AR to a set of marketing materials we prototyped for Studio McGuire’s The Invited, a CreativeXR-funded experience that reimagines the story of Dracula with a pop-up book and AR technology. I also discuss the results of evaluating The Invited’s research-informed promotion on audience, outlining key learnings about how to communicate the magic of AR content to new audiences.

Los parásitos apicomplejos utilizan diversos vertebrados como hospedadores, incluido el ser humano. La detección de estos protozoarios en la fauna silvestre evidencia la contaminación biológica del medio y la existencia de ciclos silvestres, lo que relacionaría su contacto con animales domésticos/seres humanos, debido al avance antropogénico sobre los ambientes naturales. El objetivo del presente trabajo consistió en recopilar información sobre estudios parasitológicos, serológicos y moleculares de los géneros Sarcocystis, Toxoplasma, Neospora y Cryptosporidium en especies de la fauna silvestre presente en Argentina. Se seleccionaron 48 trabajos en los que se analizaron especies silvestres de roedores, cánidos, cérvidos, marsupiales, primates, camélidos sudamericanos, cingulados, félidos, mustélidos, suinos, herpéstidos, lagomorfos, aves psitaciformes y gecónidos. El género parasitario reportado en mayor cantidad de provincias fue Sarcocystis, seguido de T. gondii, N. caninum y por último, Cryptosporidium. La condición de vida libre o en cautiverio y los hábitos etológicos de los animales silvestres, entre otros factores, influyeron en la dinámica de la interacción parásito-hospedador y en la presentación de estas infecciones.

A study was conducted on the peculiarities of electric energy transport in the power supply systems of the PJSC “Rosseti Volga” – “Orenburgenergo” branch for the period 2020 – 2023. The structure of the company is described, the characteristics of the main elements of the studied electric networks are provided, and an assessment of the balance of electric energy transmission in and out of the company's networks is presented. Based on information published in the open press, an analytical assessment of the accident rate in the company's electrical networks was carried out on a monthly basis for each year of the study period. The influence of seasonal factors on the number of emergencies during the study period is examined. The consequences of emergency shutdowns, in terms of the amount of electrical energy undersupplied to consumers, are evaluated. Based on the proposed classification, an analysis of the failure intensity was performed, and the percentage of failures of various intensities was established. Based on data for the first half of 2020 and 2023, a detailed analysis of the main causes of damage to elements of the electrical networks was carried out. The percentage ratio of the number of failures attributed to the most common causes to the total number of outages during the study period was established. The data obtained on the causes of emergency outages were compared with similar indicators in the electrical networks of other branches of PJSC Rosseti Volga. General scientific methods, as well as numerical analysis methods, were used in conducting the study. Visualization of the results of the analysis is presented using the technical capabilities of the MATLAB graphics editor. The results of this research may be of interest to the management of electric grid companies, as well as to researchers and engineers engaged in studies related to the reliability of power supply during the transmission of electric energy via overhead power lines.

Radar probing is a system for experimental study of various physical objects and environments, widely used both in longrange objects (for example, in remote sensing of the Earth, atmosphere and space objects), and in short-range objects: non-destructive testing, medical diagnostics, etc. The operating principle is based on the Doppler effect. It allows recording the movement of surface areas in the range of speeds from several nanometers per second to transonic, with registration of the frequency spectrum of oscillations. The main advantages of the method are the contactless, non-disturbing nature of measurements, their continuity, allowing for real-time diagnostics, high potential accuracy, as well as the ability to determine the internal structure of objects and environments that are transparent to probing radiation. The measuring complex developed by VtBIS LLC based on the system allows determining the position of the blades relative to each other in a working turbine at a rotation frequency of up to 15,000 rpm, which allows measuring the natural frequencies of turbine blade oscillations and the amplitudes of forced blade oscillations, as well as measuring the amplitude-frequency characteristics of forced oscillations of a blade oscillating in an external alternating magnetic field. The operability and reliability of such measuring equipment is confirmed by experimental data. This makes it possible to use it as a tool for studying the state of a blade assembly in gap measurement systems or for the discrete-phase method in order to improve the efficiency of its operation.
