Authors: Тарасенков А.Н.
Published: December 2024

Космический аппарат Transiting Exoplanet Survey Satellite (TESS) получил большое количество высокоточных фото- метрических данных, которые можно использовать для решения огромного количества астрономических задач. Но точности и полноты данных, предоставляемых открытым архивом данных TESS, не всегда достаточно для их реше- ния. Поэтому, мы представляем простой, но мощный конвейер на основе пакетов Lightkurve и Astrobase для обработки и анализа сырых данных TESS. Мы также приводим краткий обзор наших исследований, в которых мы используем данные TESS, проанализированные с помощью этого конвейера. Мы проводим программу поиска и подтверждения переменных звезд с использованием архивов кадров малых фотометрических телескопов Астрономического инсти- тута им. П. К. Штернберга (ГАИШ) и Института астрономии РАН (ИНАСАН), в которой используем высокоточную фотометрию TESS и обзора ZTF. Мы также проводим картирование хромосферно-активных звезд, используя кривые блеска, полученные из необработанных данных TESS с помощью нашего конвейера. Также мы приводим фотометрию карликовых новых и других транзиентных астрономических объектов на основе нашей обработки данных TESS.

Transiting Exoplanet Survey Satellite (TESS) spacecraft obtained a large amount of high-precision photometric data, which can be used to solve a huge number of astronomical problems. But the accuracy and completeness of the data provided by the TESS open data archive is not always enough to solve them. So we present simple but powerful pipeline based on Lightkurve and astrobase, for raw TESS data reduction and analysis. We also present a short overview of our research in which we use TESS data, analysed using this pipeline. We are conducting a program to search and confirm variable stars using archives of frames from small photometric telescopes of Sternberg Astronomical Institute (SAI) and Institute of Astronomy of the Russian Academy of Sciences (INASAN), in which we use high-precision photometry of TESS and Zwicky Transient Facility (ZTF). We also conduct mapping chromospherically active stars using light curves extracted from raw TESS data by our pipeline. We also present photometry of dwarf novae and other transient astronomical objects based on our processing of TESS data.

Published: December 2024

Гамма-всплески — это одни из самых ярких транзиентных электромагнитных явлений во Вселенной. Несмотря на многолетние исследования их природа до конца не выяснена. Предполагается, что измерения линейной поля- ризации гамма-всплесков позволят отличить разные модели излучений этих явлений. Для измерения поляризации гамма-излучения используются сегментированные сцинтилляционные детекторы, которые позволяют не только из- мерить поляризацию, но и уменьшить эффекты мертвого времени, а также определить положение источника на небе. В работе проведено моделирование сегментированного детектора с помощью программного пакета Geant4. Исследо- вана эффективность локализации источника таким детектором. Приведена методика экспериментальной калибровки детектора для измерения мертвого времени.

Gamma-ray bursts are among the brightest transient electromagnetic phenomena in the Universe. Despite years of research, their nature has not been fully clarified. It is assumed that measurements of the linear polarization of gamma-ray bursts will make it possible to distinguish different radiation models of these phenomena. Segmented scintillation detectors are used to measure the polarization of gamma radiation, which make it possible to measure polarization, reduce the effects of dead time and determine the position of the source in the sky. We performed a simulation of the segmented detector using the Geant4 software package. The effectiveness of source localization using such a detector has been investigated. The method of experimental calibration of the detector for measuring dead time is presented.

Published: December 2024

Работа направлена на изучение околосолнечных и околоземных астероидов и их связей. Исследования в области изучения околосолнечных астероидов важны для развития эволюционной теории Солнечной системы. На данный момент отсутствует теория динамики солнечного ветра и изучение поведения околосолнечных и околоземных астеро- идов вносит свой вклад в построение данной теории. Принимается, что околосолнечные астероиды можно исследовать как околоземные астероиды, если они находятся в непосредственной близости от Солнца, имеют малые размеры и малые перигелийные расстояния. В работе применяется созданная авторами имитационная модель динамики около- солнечных астероидов с малыми перигелийными расстояниями. Рассматривается пополнение пылевых образований и колец, существующих во внутренней части Солнечной системы. Изучаются распределения по орбитальным пара- метрам – построены зависимости эксцентриситета от большой полуоси орбиты и наклона орбиты от большой полуоси орбиты для NEA. Построены и проанализированы температурные зависимости - зависимость изотермической и сфе- рической температуры и субсолнечной температуры от большой полуоси орбиты для NEA. Получены зависимости по цветовым индексам и проведен их анализ. Результаты данной работы полезны для понимания физики динамических процессов как Солнечной системы, так и, как следствие, вносят вклад в исследование эволюции систем экзопланет.

The work is aimed at studying near-solar and near-Earth asteroids and their connections. Research in the field of studying near-solar asteroids is important for the development of the evolutionary theory of the Solar System. Currently, there is no theory of solar wind dynamics, and the study of the behavior of near-solar and near-Earth asteroids contributes to the construction of this theory. It is accepted that near-solar asteroids can be studied as near-Earth ones if they are in close proximity to the Sun, have small sizes and small perihelion distances. The work uses a simulation model of the dynamics of near-solar asteroids with small perihelion distances created by the authors. The replenishment of dust formations and rings existing in the inner part of the Solar System is considered. The distributions of orbital parameters are studied – the dependences of the eccentricity on the semi-major axis of the orbit and the orbital inclination on the semi-major axis of the orbit for NEAs are constructed. Temperature dependencies were constructed and analyzed – the dependence of isothermal and spherical temperature and subsolar temperature on the semi-major axis of the orbit for NEAs. Dependencies on color indices were obtained and analyzed. The results of this work are useful for understanding the physics of dynamic processes in both the Solar System and, as a consequence, contribute to the study of the evolution of exoplanet systems.

Authors: Arı Ayşe Sümeyye , Özensoy Habibe Selmin , Kahraman Fatih Ahmet , Oğuztürk Hakan
Published: December 2024

Aims: As the number of emergency department (ED) patients increases, medical-legal lawsuits also increase. Doctors must have medicolegal knowledge. Interventional procedures are frequently performed in EDs. Our study aims to evaluate emergency physicians' knowledge, attitudes, and behaviors regarding their medical-legal responsibilities regarding frequently performed interventional procedures.
Methods: This is a prospective questionnaire study in a single center. The questionnaires were answered via Google® Form. Participants were asked questions about their demographic characteristics and education levels. The study was applied to physicians working in the ED from October 10 to 20, 2023.
Results: A questionnaire was sent to 155 physicians. One hundred forty-three responded to the questionnaire. Most participants (88%) were found to have received training on interventional procedures performed in the ED, but their level of knowledge about their legal responsibilities during interventional procedures was lower (18.2%). It was observed that specialist physicians and faculty members had better awareness of interventional procedures in the Postgraduate Emergency Medicine (PEM) training program than assistant physicians (p<0.001). As age and professional experience increased, the training received and awareness levels increased (p<0.001).
Conclusion: Specialists and faculty members have higher legal knowledge, while assistant physicians face difficulties in fulfilling their legal responsibilities. Findings highlight the need for early legal education in emergency medicine for their legal responsibilities in invasive procedures.
A Critical Discourse Analysis of George W. Bush's Fifth Anniversary of September 11thSpeech
Authors: Jassim Abdulmalek Hammed
Published: December 2024

Nowadays, methods of justification and satisfactory strategies are very important in social interaction and other spheres of life, particularly when tackling political affairs. In order to convince others to support them on certain subjects, politicians as well as all other people rely on a variety of techniques. Politicians who want to dominate their countries must unavoidably possess some unique linguistic traits or qualifications that allow them to do so and enable them to continue carrying out their objectives. This study, which is a critical discourse analysis, explores the relationship between language and the social political contexts in which it is used. The main two goals of this study are first to expose the way followed by the speaker to make his thoughts and plans seem real, applicable and achievable, and identify the linguistic strategies used by politicians to rally support for what they aim to carry out. Through their speeches, they attempt to gain agreement and support from both allies and opponents. The analysis will be based on T. Huckin (1997)categories and Fairclough (1995)model to qualitatively analyze the political oration of president George W. Bush on September 11, 2001, the fifth anniversary of the assault on the World Trade Center in New York. What can be extracted after analyzing this political oration is that being a good politician required you to be a good speaker. The president depends on a supportive way of exposing his thoughts i.e., telling some heroic stories or situations. The president succeeded in employing some linguistic strategies such as foreground, background, omission ... etc. with connection to the social situation and what improves his success is winning a second presidential election at that time.
Navigating Anti-Discourse in Rita Dove's “Canary” and “Banneker” viaFoucauldian Theory of Transgression
Authors: Shartooh Abbas Ali , Hassan Mohammed Fleih
Published: December 2024

Fighting for the sake of self-realization becomes a goal for African-American people, particularly women. Those people have passed through unpleasant stages of stereotyping and devaluing by those in charge as part of maintaining the Whites’ privilege. As an African-American poet, Rita Dove finds it a must for her to speak about oppression that her alike have passed through. For this reason, she devotes her poetry to reflect the real heritage of her folks away from the misrepresentation that those people have via the dominant discourse. Despite the considerable number of past studies that have approached the poetry of Dove through different perspectives, little ink, if any, is given to study her poetry in light of Foucault’s ideas. Thus, the current study aims to investigate the resisting discourse utilized by Dove in two selected poems in light of Foucault’s Theory of Transgression(1963). Moreover, the concept of Problematization in Foucault’s aforementioned theory is used as a methodological tool in analyzing the poem. Two poems “Canary and Banneker” of Dove's Collected Poems1974-2004 (2016) have been used for data analysis to show how Dove problematizes the falsely created norms against African-Americans in order to present her anti-discourse against the white dominant society. As such, the study concludes that Dove through presenting two successful African-American characters, Holiday and Banneker, refutes the white-made fabrications that African-Americans are unaccustomed and of a low intelligence to compete a white man. Presenting Holiday as a brilliant jazz singer and Banneker as a genius scholar who made exceptional discoveries is a resisting strategy followed by Dove to show that African-Americans are brilliant and if they are given the opportunity, they can rival the whites
The Methods of Cartographic Representation in Information Systems Programs (GIS),and Their Role in Preparing Thematic Maps
Authors: Dhahi Omar Naji Omeir
Published: December 2024

The preparation of any good map requires choosing the appropriate cartographic representation method with all its means and methods of representation, because the map is an important and necessary research tool for the geographer for its effective role in delivering information quickly and facilitates understanding and perception compared to numbers, tables and explanations, and here the role of geographic information systems in cartography is clear, as the use of these systems leads to the design of maps very accurately because of the variety of methods used to encode or represent natural and human phenomena on objective maps and with high technology.The research touched on all the cartographic representation methods used to represent data in thematic maps and identified all aspects related to the capabilities of geographic information systems in drawing and designing the Thematic Map and it turned out that GIS programs have a high potential in cartographic representation, but there are a number of quantitative representation methods are not available in these GIs programs and it is necessary to rely on other cartographic programs specialized in mapping such as (QGIS) (GRASS3.4), (ScapeToad-v11), (GEO DA1.5) .
Hemispheric Asymmetry of Annual/Semi-Annual Oscillations in Mesospheric Neutral Winds and Pressure Between Northern and Southern High Latitude Regions
Authors: Kam Hosik , Kim Jeong-Han , Lee Changsup , Kim Yong Ha
Published: December 2024

We present oscillating features from long-term neutral wind (meteor radar) and pressure (microwave limb sounder) measurements at Esrange (67°N, 20°E, 2007–2018) in the northern hemisphere and King Sejong Station (KSS; 62°S, 58°W, 2007–2017) in the Southern Hemisphere using the Lomb-Scargle periodogram and wavelet analysis. In zonal winds and pressure, we estimated the height profiles for the amplitude ratio between annual oscillation (AO) and semi-annual oscillation (SAO) at both sites. Over KSS, the ratio indicates that SAO increases with altitude, whereas AO decreases, with SAO becoming the dominant oscillating component at around 90 km. However, the ratio mostly remains constant with an altitude due to the steady formation of a westward wind field throughout the height in summer. More intensive gravity wave activity over KSS drives meridional residual circulation in summer mesopause, creating a more powerful SAO signature above 90 km.

Introduction: The prevalence of respiratory diseases among pediatric populations constitutes a substantial public health concern, shaped by inherent biological susceptibilities and environmental determinants. Temporal variations critically influence the occurrence and severity of these diseases. Material and Methods: In this study, recent literature on respiratory diseases in children was analyzed, focusing on seasonal factors, environmental impacts, and prevention strategies such as vaccination, hygiene, and indoor air pollution control. Results and discussion: Respiratory diseases, such as Influenza, Bronchiolitis, and Asthma, demonstrated higher incidence during periods of low temperatures and high humidity. In colder months, increased viral transmission was associated with prolonged stays in enclosed spaces. Conversely, in tropical climates, rainy periods heightened risks due to factors related to humidity and mold exposure. Vaccination, hygiene practices, and improved ventilation in indoor environments showed significant reductions in severe cases. Seasonality has a direct impact on the dynamics of respiratory diseases. It is essential to adopt and promote measures such as awareness campaigns, vaccination, and reductions in indoor air pollution. However, the implementation of these strategies is limited by socioeconomic barriers. Conclusion: Seasonal impacts and the adoption of preventive measures are fundamental to reducing the prevalence of respiratory diseases in children, allowing for an improvement in their quality of life.

Published: December 2024

This research aims to explore relationships among science teacher candidates’ awareness about sustainable development, attitudes and behaviors against environmental problems. For this purpose, initially, pre-service science teachers’ (PSTs) awareness about sustainable development, attitudes and behaviours towards environmental problems were determined. Then, the relation-ships among PSTs’ awareness about sustainable development, attitudes and behaviours towards environmental problems were explored. In the current study, correlational research method was conducted. The sample of research were 712 pre-service science teachers from four different public universities in Istanbul,Turkey. The data were collected with 3 different data collection tools which are ‘Sustainable Development Awareness Scale’, ‘Environmental Problems Attitude Scale’ and ‘Environmental Problems Behavior Scale’. Descriptive statistics and Pearson correlation analysis were conducted in data analysis. Results showed that PSTs’ awareness about sustainable devel-opment and attitudes towards environmental issues are high level while their behaviours towards environmental problems are medium level. Furthermore, both the relationship between PSTs’ awareness of sustainable development and PSTs’ attitudes against environmental problems and the relationship between PSTs’ attitudes towards environmental issues and their behaviours towards environmental issues are positively directed medium level. In addition, the relationship between PSTs’ awareness of sustainable development and PSTs’ behaviors against environmental problems is positively directed low level. This research is crucial in terms of provides information about PSTs’ awareness of sustainable development, attitudes and behaviours toward environmental issues to researchers, educators, curriculum designers for teachership programs, academicians and educa-tional policy makers.
Influence of Stigmatization on Mental Health Disorders among Children Associated with Armed Forces or Armed Groups in Borno State: How Important is Perceived Social Support?
Authors: Abege Terna , Tyokyaa Tertindi Lordsent , Nyifan Hope Hembafan
Published: December 2024

This research examined the mediating role of perceived social support in the relationship between stigmatization and mental health disorders among Children Associated with Armed Forces or Armed Groups (CAAFAGs). The cross-sectional survey involved 169 CAAFAGs selected from 7 Local Government Areas in Borno State who were within the age range of 7 – 17 years with the mean age of 13.48 years (Std.=3.01). The multi-stage sampling involving stratified and purposive techniques was used in selecting the participants. Data were collected using the Stigma Scale, Interpersonal Support Evaluation List (ISEL)–12, and Depression, Anxiety and Stress Scale (DASS). Results from data analysis showed that stigmatization contributed a large percentage to the overall mental health disorders observed among Children Associated with Armed Forces or Armed Groups (CAAFAGs). Specifically, CAAFAGs who were discriminated against had difficulty disclosing their status, exhibited self-stigma and tended to suffer higher mental health disorders (i.e. depression, anxiety and stress). Furthermore, it was found that, although perceived social support could not completely eliminate the effect of stigmatization on mental health disorders, it has the potential to lower the effect of stigmatization (which indicates partial mediation). It was therefore recommended that apart from supporting the CAAFAGs with tangible items like food, water, clothing and shelter, the government and NGOs should further hold community reintegration workshops, dialogue, mediation on reintegration challenges and social cohesion activities that are capable of building the children’s self-esteem and further enhancing their mental health.
Occupational mismatch in the labour market of selected EU countries
Authors: Obadić Alka , Viljevac Viktor
Published: December 2024

Purpose: This paper aims to examine the occupational structures of selected EU member countries and assess their compatibility with the labour market demands, aiming to identify potential structural mismatches. The search evaluates the alignment between existing knowledge and skills in specific qualifications and those required by employers, utilizing disaggregated data from registered employment offices in Austria, Croatia, Slovenia, and Spain, spanning from 2010 to 2022.Methodology: Methodologically, the study uses Beveridge curves, labour market tightness, and matching efficiency estimates to measure the matching needs of employers and unemployed job seekers within various occupation groups. The analysis focuses on the impact of economic downturns and fluctuations in unemployment rates on different occupation groups, with a particular emphasis on more complex and better-paid occupations.Results: Results indicate that workers in higher-skilled occupations may experience a more resilient position within the aggregate labour market trends. However, the study reveals that deviations from these trends among occupation groups are relatively minor, underscoring the substantial influence of overall labour market conditions on all segments.Conclusion: The research finds that differences in occupation groups have a limited impact on the broader labour market trends. Regardless of occupation complexity, improvements and deteriorations in labour market conditions affect all groups uniformly. These findings suggest a nuanced interplay between occupational structures and aggregate labour market dynamics, emphasising the need for comprehensive policy considerations to address potential mismatches and promote overall labour market efficiency.
The cost of fiscal austerity
Authors: Škuflić Lorena , Vučković Valentina , Walter Dora
Published: December 2024

Purpose: This paper analyses economic and social impact of fiscal austerity policies on economic growth and income distribution. In response to the European public debt crisis, austerity measures were implemented in 2010 to decrease the budget deficit and avoid the default of the government debt, but have also caused negative effects on the whole economy. Methodology: In order to evaluate the effectiveness of fiscal austerity, the synthetic control method (SCM) is applied by creating a synthetic counterfactual from European countries. Greece is used as an example to assess the impact of the aforementioned policy due to having experienced fiscal consolidation to a much larger extent than other crisis-affected countries. Results: Fiscal austerity causes a decline in real GDP per capita compared to its pre-austerity level. Additionally, it results in higher unemployment and a more unequal distribution of income in the initial years following the treatment. Conclusion: The objective of fiscal austerity, i.e. the reduction of the debt-to-GDP ratio, is frequently not achieved due to negative effects of these measures on GDP. Fiscal austerity may occasionally be unavoidable, but even in these cases, deliberate measure-taking is required to prevent the increase in unemployment and income inequality, as witnessed after the global financial crisis.

Abstract. We investigate the formation mechanism of a tropopause cirrus cloud layer observed during the Balloon measurement campaigns of the Asian Tropopause Aerosol Layer (BATAL) over Hyderabad (17.47° N, 78.58° E), India, on 23 August 2017. Simultaneous measurements from a backscatter sonde and an optical particle counter on board a balloon flight revealed the presence of a subvisible cirrus cloud layer (optical thickness ∼ 0.025) at the cold-point tropopause (temperature ∼ −86.4 °C, altitude ∼ 17.9 km). Ice crystals in this layer are smaller than 50 µm with a layer mean ice crystal number concentration of about 46.79 L−1. Simultaneous backscatter and extinction coefficient measurements allowed us to estimate the range-resolved extinction to backscatter coefficient ratio (lidar ratio) inside this layer with a layer mean value of about 32.18 ± 6.73 sr, which is in good agreement with earlier reported values at similar cirrus cloud temperatures. The formation mechanism responsible for this tropopause cirrus is investigated using a combination of three-dimensional back trajectories, satellite observations, and ERA5 reanalysis data. Satellite observations revealed that the overshooting convection associated with a category 3 typhoon, Hato, which hit Macau and Hong Kong on 23 August 2017, injected ice into the lower stratosphere. This caused a hydration patch that followed the Asian summer monsoon anticyclone to subsequently move towards Hyderabad. The presence of tropopause cirrus cloud layers in the cold temperature anomalies and updrafts along the back trajectories suggested the role of typhoon-induced waves in their formation. This case study highlights the role of typhoons in influencing the formation of tropopause cirrus clouds through stratospheric hydration and waves.

Abstract. Peatland management practices, such as drainage and restoration, have a strong effect on boreal peatland methane (CH4) fluxes. Furthermore, CH4 fluxes are strongly controlled by local environmental conditions, such as soil hydrology, temperature and vegetation, which are all experiencing considerable changes due to climate change. Both management practices and climate change are expected to influence peatland CH4 fluxes during this century, but the magnitude and net impact of these changes is still insufficiently understood. In this study, we simulated the impacts of two forest management practices, rotational forestry and continuous cover forestry, as well as peatland restoration, on hypothetical forestry-drained peatlands across Finland using the land surface model JSBACH (Jena Scheme for Biosphere–Atmosphere Coupling in Hamburg) coupled with the soil carbon model YASSO and a peatland methane model HIMMELI (Helsinki Model of Methane Buildup and Emission for Peatlands). We further simulated the impacts of climatic warming using two RCP (Representative Concentration Pathway) emission scenarios, RCP2.6 and RCP4.5. We investigated the responses of CH4 fluxes, soil water-table level (WTL), soil temperatures and soil carbon dynamics to changes in management practices and climate. Our results show that management practices have a strong impact on peatland WTLs and CH4 emissions that continues for several decades, with emissions increasing after restoration and clearcutting. Towards the end of the century, WTLs increase slightly, likely due to increasing precipitation. CH4 fluxes have opposing trends in restored and drained peatlands. In restored peatlands, CH4 emissions decrease towards the end of the century following decomposition of harvest residue in the top peat layers despite increasing WTLs, while in drained peatland forests sinks get weaker and occasional emissions become more common, likely due to rising WTLs and soil temperatures. The strength of these trends varies across the country, with CH4 emissions from restored peatlands decreasing more strongly in southern Finland, and forest soil CH4 sinks weakening most in northern Finland.
The new (Black) civics: How popular media cultivates connected learning, and civic engagement among Black college students
Authors: Evans Jabari , Ezenna Odera
Published: December 2024

Through interviews with 28 college students majoring in journalism, this study examines how African American youth and young adults uniquely develop civic mindsets and cultivate critical media literacy skills. Related to their desire to create counternarratives of racist representations of Blackness in popular media, imagine possibilities for their daily life, and promote pride in their local communities, findings in this study suggest African American youths use popular media to form unique pathways to connected learning (CL) capabilities, civic engagement, and positive individual trajectories. Three themes emerged from our interviews on media engagement: 1) learning through discourse on racial injustice in news media; 2) learning of Black-oriented community obligation via civic media; and, 3) participating in/observing political activism through social media. This article concludes by arguing that more consideration must be given to the racialized social learning practices that grow around digital devices and tools that shape how they are used and understood by African American youth.

Published: December 2024

This thematic issue brings together timely research in global case studies pointing to similarities and differences among youth’s digital civic engagements and activism across different cultural contexts. In so doing, the authors’ contributions point to the intersection of a number of foci in digital studies: youth, digital media, democracy, and public discourse in the digital commons. As a global collaboration, the special issue offers insight into both transnational phenomena and culturally situated perspectives on young people’s digital media use in a time of great change in world democracies. Bringing together case studies from around the world, the issue highlights how youth are increasingly engaging in the digital commons as a form of civic engagement (writ large) along a number of axes. Given the international breadth of authorship, the special issue allows for international comparison of key issues across three sections: civic engagement, mediated activism, and digital rights. The special issue will be of interest to scholars across disciplines and fields including but not limited to digital studies, youth studies, and digital civic engagement.
“I trust how it works — It is a democracy!” Young citizens on trust, information, civic engagement, and democracy
Authors: Stald Gitte
Published: December 2024

The objective of this paper is to investigate and discuss young Danish citizens' trust in information, citizenship, and democracy with a focus on the intersecting conditions for their civic engagement and democratic citizenship. The argument and the findings connect three points that strongly relate to questions of trust and distrust: Young citizens are the bearers of future sustainable democracy; Informed citizenship redefined is a vital element in the foundation of sustainable democracy; civic engagement and democratic citizenship depend on the collective trust in allowing new forms of information and informed citizenship, and to support young generations' development of democratic self-efficacy. Empirically, the paper draws on a case study that investigates the problem through 16- to 24-year-old Danes' narratives. The theoretical framing combines conceptions of trust to reduce complexity, the interdependency of trust and distrust, and rationality as an essential motivation for relying on trust.
“If I weren’t an activist, I’d buy an old Nokia and I’d be OK”: Youth wellbeing, digital media, and activism
Authors: Supa Markéta , Neag Annamária , Kligler-Vilenchik Neta
Published: December 2024

For youth activists, digital media are a central tool for awareness raising and mobilisation. At the same time, the pressure to be constantly connected and the negative responses one can encounter through social media, can be significant stressors on youths’ wellbeing. Drawing upon a year-long critical comparative ethnographic research project with Fridays For Future youth climate justice activists in Czechia and Hungary, this paper analyses the multifaceted role of digital media in youth activists’ wellbeing. On one hand, youth activists encountered varied psychological, social, and physical challenges connected to digital media use, which caused stress and contributed to burnout. On the other hand, they individually and collectively developed diverse coping strategies and mechanisms, as well as digital literacy, which were supported by the movement’s community of activists. This in turn strengthened their resilience and positively contributed to their wellbeing. Ultimately, the youth activists’ wellbeing appeared to rely on their own ability to constantly balance between the many challenges encountered related to digital media use for activism, and the resources required to deal with these challenges. Our findings carry important implications for supporting youth activists’ wellbeing.
Gen Z's gendered divergences in the U.S. 2024 election: Digital engagement, education, and politics
Authors: Robinson Laura
Published: December 2024

On the eve of the 2024 U.S. presidential election, the media was abuzz with Gen Z’s historic divergence at the ballot box. To understand Gen Z’s political fracturing, the research reveals how this election is at the nexus of larger gendered polarization in terms of digital activities and educational trajectories. In doing so, the research brings together these foci and puts them into dialogue with one another regarding Gen Z: the first digital generation. Focusing on a revelatory population, this study illuminates the voices of Gen Z socialized in a community marked by long term economic insecurity in an agricultural belt of California. Taking inspiration from Hochschild’s examination of the “crisis of men” vis-à-vis the 2024 election in the U.S., the analysis draws on her concepts of the “pride paradox” and the “pride economy.” Findings reveal linkages between gender, social media versus gaming, and going to college or “going to the trades.” All of these are driving gendered divergences within Gen Z’s media prosumption with important consequences for postsecondary educational trajectories which have implications for political stances. The research closes with a discussion of the impact of digital activities on identity projects that can translate into political stances, as well as the far-reaching implications of these processes for Gen Z globally in light of recent European elections.

Tüketici kitlenin beklentilerinin marka tarafından karşılanmaması durumu sinik tüketici eğilimleri arasında yer alan tüketici boykotlarına neden olmaktadır. Yürütülen bu araştırma çerçevesinde bir sinik tüketici davranışı olan tüketici boykotları için bilgilendirme ve yayılma noktasında büyük önem taşıyan afişler göstergebilimsel açıdan çözümlenmiştir. İsrail destekçisi olarak görülen markalara yönelik tasarlanan afişler üzerinden inceleme yapılmıştır. Afişlerin kaynağının net olarak belirlenebilmesi adına 24 Ekim 2023 tarihinde Bosphorus Global isimli Sivil Toplum Kuruluşu tarafından X sosyal medya platformunda yayınlanan dört boykot afişi araştırmanın örneklemini oluşturmaktadır. Örneklemi oluşturan afişler Barthes’ın göstergebilimsel çözümleme perspektifi kullanılarak analiz edilmiştir. Analizler sonucunda tüm afişlerde kırmızı renk kullanımı ve hasthaglere yer verildiği ortaya konulmuştur. Kırmızı rengin dikkat çekme özelliğinden faydalanılarak afişlere maruz kalan bireylerin dikkatinin afiş üzerinde toplanması amaçlanmıştır. Afişlerde yer alan kırmızı renkte lekeler ise insan beyninde tehlike, ölüm gibi kavramları uyandırması bakımından saldırılarda yaşanan ölümlerin simgesi olarak kullanılmıştır. Hashtagler ise boykot eylemlerinin sosyal medya platformları üzerinden yayılımını güçlendirmek adına tüm afişlerde kullanılmıştır. Hashtaglere İngilizce ve Türkçe olarak afişlerde yer verilmiştir. İngilizce dilinin kullanılmasıyla dilin evrenselliğinden yararlanılarak global bir çağrıya dönüşmesi amaçlanmıştır.

Authors: Alpuğan Zeynep
Published: December 2024

The digital age has ushered in significant changes in the landscape of child development, with digital media becoming an integral part of the lives of children from infancy through adolescence. This manuscript provides a comprehensive review of the multifaceted impacts of various forms of digital media, including television, video games, social media, and educational software, on children’s cognitive, social, and emotional development. It explores how digital media can both enhance learning through interactive educational tools and pose risks such as diminished attention spans and potential social isolation. The role of parental mediation is highlighted as a crucial factor in moderating digital media’s effects, emphasizing strategies such as co-viewing, setting usage limits, and guiding online interactions. Additionally, the manuscript delves into the implications of emerging technologies like augmented reality (AR) and virtual reality (VR), discussing their potential to offer immersive learning experiences and their unique challenges. By integrating psychological theories such as Cognitive Load Theory, Social Learning Theory, and Attachment Theory, this review deepens the understanding of how digital media influences child development and provides insights aimed at helping parents, educators, and policymakers develop effective strategies to harness the potential of digital media while safeguarding healthy child development.

Financial systems can support sustainable development by promoting investments considering environmental and social impacts, developing green finance, and ensuring financial inclusion. Incorporating financial technology into financial services can also help increase sustainable investment and financial inclusion. Therefore, a study was conducted to investigate the effect of financial development and financial inclusion, FinTech, renewable energy, and economic growth on the ecological footprint of Turkiye from 2005 to 2023 using the ARDL method. The study also focused on the non-linear effect of financial development on ecological footprint and the moderating role of FinTech in the relationship between financial development and ecological footprint. The study revealed an inverted U-shaped relationship between financial development and ecological footprint in the long run. Additionally, in the long run, FinTech and economic growth increase environmental degradation, while financial inclusion and renewable energy decrease environmental degradation. In the short run, no significant relationship was found between financial development, renewable energy, and environmental degradation. On the other hand, FinTech and financial inclusion are found to decrease environmental degradation, while economic growth is found to increase environmental degradation. The results suggest that Turkiye needs to consider the targets of SDG7 (Affordable and Clean Energy), SDG8 (Decent Work and Economic Growth), and SDG17 (Partnerships for the Goals), as well as interactive policies, to achieve the targets of SDG13 (Climate Action).

Background: Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV). Following initial infection, a person may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections.
Objective: To reveal the Clinical Conditions and Co-infection rates by different infectious agents among the patients of HIV-AIDS.
Materials & Methods: It is a descriptive type of cross-sectional study. A pre-tested, semi structured and modified interview administrated questionnaire was used to collect data. Non - randomized, sequential, and purposive and plenitude sampling methods have been tried by following face to face interview of the participants.
Results & Discussions: In this study the percentage of male was 63% and the percentage of female was 37%. 49% respondents were in 33-47 years of age groups. In this study 55% respondents were up to primary education. We found out that 36% of the respondents were part-time workers. It was seen that 44% respondents’ monthly family income was between 10,000 – 20,000 BDT. It was observed that 98% of the respondents knew about HIV/AIDS. It was observed that 63% of the respondents knew about the causative agent of HIV/AIDS. Majority of the respondents were HIV positive for more than 3 years.51% of the respondents were informed that HIV/AIDS is not infectious. 82% of the respondents were aware that HIV/AIDS is not curable by drugs. 71% of the respondents knew about the symptoms of HIV/AIDS. 92% respondents in unsafe physical relation HIV/AIDS transmits. Here maximum respondents had different infections.
Conclusion: It was seen that the respondents of this study did not have knowledge on HIV/AIDS at satisfactory level. Still a portion of them is wrong and replied incorrect answers or did not know about different issues regarding HIV-AIDS though some of them were replying satisfactorily.

Mechanisms of niacin skin test pathogenesis in patients at clinical high risk for psychosis and schizophrenia
Authors: Nastas Igor , Boronin Larisa
Published: December 2024

Introduction. Elevated or imbalanced levels of markers of oxidative stress and inflammation are often observed in various somatic pathologies and mental disorders, including schizophrenia. Purpose of the study. This study aims to investigate the mechanisms of pathogenesis and the evidence supporting the use of niacin skin and oral tests in patients with schizophrenia. Materials and methods. A literature review was conducted on the specific reactions to the niacin skin or oral test in patients with schizophrenia, first-episode psychosis, and those at clinical high risk for psychosis (CHR-P). Evidence-based data up to and including 2024 were reviewed, with 48 literary sources selected. Results. An attenuated niacin-induced flush, coupled with low vitamin B3 levels, an imbalance in the Redox-Ratio and omega-3/omega-6 fatty acids, and elevated phospholipase A2 levels, are the main evidence-based findings associated with schizophrenia. Conclusions. The niacin skin and oral tests in patients with schizophrenia and those at high risk for psychosis are characterized by an abnormal response to niacin. Additional markers may further validate positive test results for niacin.
