Published: December 2024

Abstract. Water surface temperature (WST) is a crucial parameter in aquatic systems, influencing both water quality and hydrodynamic conditions of these systems. Landsat 9, the latest satellite in the Landsat program, offers a unique opportunity for retrieving Earth's surface temperature data. Despite numerous efforts to develop methods for retrieving surface temperature from remote sensing data, there have been relatively few studies comparing the performance of these methods. The main objective of this study was to evaluate and compare the effectiveness of various methods for estimating WST in a reservoir on Argentina using thermal images from the new Landsat 9 satellite. WST retrievals were obtained from Landsat Collection 2 (C2), Level 2 products, as well as from the Single-Channel (SC) method and a Split-Window (SW) algorithm applied to Landsat C2, Level 1 images. The comparative analysis showed that, although all three methods performed similarly, the Split-Window method proved to be the most effective for estimating WST in the Río Tercero reservoir (R2 = 0.99, RMSE = 0.77 °C). Finally, this method was used to produce detailed WST distribution maps for the studied reservoir.

Abstract. The Southern Patagonian Icefield is experiencing rapid retreat and thinning in its calving glaciers. To better understand the dynamics of these changes, we generated ice flow line maps for the Viedma, Upsala, and Pio XI glaciers during 2017–2018. An evenly spaced streamline placement algorithm, integrating topographic and flow curvature criteria, was employed to calculate over 2,700 streamlines per glacier at a 50-meter resolution. The algorithm's performance was assessed by comparing the generated flow lines with manually digitized reference lines, resulting in a mean error, standard deviation, and root mean square error of 57.35, 33.62, and 66.46 meters, respectively. The resulting maps reveal detailed flow structures, highlighting flow lines from accumulation to ablation zones, increased velocities in central areas, tributary flows merging with main channels, and regions of flow convergence and divergence. Additionally, the glaciers' 3D lengths were estimated by identifying the longest ice flow lines, with Pio XI measuring 62.27 km, Viedma 54.49 km, and Upsala 51.24 km. We consider that the methodology used, along with the generated maps, provides excellent visual and analytical tools for identifying glacier areas, lengths, and shapes, defining ice origins and glacier catchment boundaries, and analysing zones of flow convergence and divergence—parameters that are critically important for understanding the dynamics, geometry, and evolution of glaciers in this region.

Authors: Pepe Massimiliano , Costantino Domenica , Alfio Vincenzo Saverio , Grimaldi Ariana
Published: December 2024

Abstract. The aim of the paper is to identify a suitable methodology for the construction of 3D City Models (3DCM) from geospatial data. Recently, the use of hybrid sensors i.e. nadiral and oblique cameras supplemented by Light Detection And Ranging (LiDAR) sensors equipped on an aerial platform, are becoming useful instrumentation for mapping urban areas. In fact, the manuscript shows the use of such instrumentation for the production of a 3D City Model processed in the City Engine environment, starting from a geomatic dataset composed of a point cloud and a series of images covering a portion of the historic centre of Bordeaux (France). The results show the quality of the 3D models in LOD3, generated on the study area, in terms of architectural details, textures and semantic contributions.

Published: December 2024

Abstract. Antarctic ice-mass balance is key to project sea-level changes, to assess future shifts in the global water cycle and ocean circulation, and to predict the fate of the White Continent. The ice mass of the Antarctic Peninsula is sensitive to the atmospheric and ocean circulation. The geographical conditions pose a challenge for modelling surface mass balance in this area. We use GRACE and GRACE Follow-On satellite gravimetry to derive a mass variation time series for the Antarctic peninsula region 2002–2024. We investigate whether these mass variations correlate with a surface mass balance model or with global climate indexes. Our analysis indicates a mass loss over two decades, mainly due to a period of enhanced mass-loss rate between 2007 and 2015. Our results suggest that interannual mass variations are primarily controlled by the surface mass balance which is influenced by the El Niño-Southern Oscillation phenomenon.
Refining lake volume estimation and critical depth identification for enhanced glacial lake outburst flood (GLOF) event anticipation

Published: December 2024

Abstract. Climate change leads to changes in glacier mass balance, including steady advancements and surges that reposition the glacier snouts. Glacier advancement can dam proglacial meltwater lakes. Within the Karakoram and surrounding regions, the positive feedback of climate change has resulted in more frequent ice-dammed glacial lake outburst floods (GLOFs), often facilitated by englacial conduits. However, the complex and multi-factor processes of conduit development are difficult to measure. Determining the lake depths that might trigger GLOFs and the numerical model specifications for breaching is challenging. Empirical estimates of lake volumes, along with field-based monitoring of lake levels and depths and the assessment of GLOF hazards, enable warnings and damage mitigation. Using historical data, remote sensing techniques, high-resolution imagery, cross-correlation feature tracking, and field-based data, we identified the processes of lake formation, drainage timing, and triggering depth. We developed empirical approaches to determine lake volume and trigger water pressure leading to a GLOF. A correlation, albeit a weak one, between glacier surge velocity and lake volume reveals that glacier surge may play a crucial role in lake formation and thus controls the size and volume of the lake. Lake volume estimation involves geometric considerations of the lake basin shape. A GLOF becomes likely when the lake's normalized depth (n′) exceeds 0.60, equivalent to a typical water pressure on the dam face of 510 kPa. These field and remotely sensed findings not only offer valuable insights for early warning procedures in the Karakoram but also suggest that similar approaches might be effectively applied to other mountain environments worldwide where GLOFs pose a hazard.
Gender Trends in Dermatology Research: Shifting Authorship Landscape in Indian Journals
Authors: Mediboina Anjali , Bhupathi Meghana , Janapareddy Keerthana
Published: December 2024

Background: Historically, research authorship has been male dominated, particularly in dermatology. Gender equity in medical research is vital for diverse perspectives and rigorous science. In India, gender trends in dermatology research among first authors remain understudied, limiting our understanding of gender inequalities in the field.
Methods: This study analyzed Original Articles, Review Articles, and Case Reports in three prominent Indian Dermatology journals from January 2017 to May 2023. The first authors' genders were determined using Namsor V.2, cross-verified with social media profiles, and authors with undetermined genders were excluded. The authors' countries were identified based on their affiliated institutions. The data was analyzed using Microsoft Excel, with a predictive analysis using the FORECAST function.
Results: Among 1,600 authors, 840 were female and 760 male. Male authors outnumbered female authors only in 2017. Female authors surpassed male authors in original articles and case reports, while fewer appeared in review articles. Predictive analysis revealed an increasing trend in female authors from 2023 to 2028, indicating evolving gender dynamics in dermatology research.
Conclusion: While the rise in female representation in medical research is promising, concerns arise when fields become predominantly female, raising questions about their perceived value. Gender disparities in compensation further underscore these concerns, as male dermatologists earn more. Addressing such disparities is crucial and recognizing these issues and actively pursuing gender equality is essential for a more inclusive and equitable future in medicine.

Published: December 2024

Introduction: Among professional athletes, high altitude training is a popular technique due to its documented success on improving cardiovascular health and athletic performance. Nevertheless, there is little consensus on the guidelines for high altitude training and competition. This review sought to summarize existing literature for acclimatization recommendations for competing at high altitudes and suggests a blueprint that could be followed by athletes and trainers. 
Methods: This paper is part of the Altitude Nondifferentiated ECG Study (ANDES) project. A non-systematic search was conducted using Pubmed, EMBASE and MEDLINE databases.
Results: Six studies were included, all of which recommended a gradual ascent before competition. The duration of acclimatization ranged from 4 days to 2 weeks depending on the magnitude of ascent. Athletes are encouraged to have pre-ascent assessments of ferritin, transferrin, hemoglobin mass, ECG, and weight with close monitoring of adverse altitude-induced complications.
Conclusion: This study provides insight on key recommendations for athletes and trainers to consider when training and competing at high altitudes. These strategies can optimize athletic performance and mitigate deleterious altitude effects that can hinder functionality and training.

Authors: Dos Santos Vitorino M. , C. Modesto Laura , C. Modesto Julia
Published: December 2024

Recently, this Journal published an interesting case study about the Moersch-Woltman syndrome that affected a middle-aged female, who had not an early diagnosis of this uncommon condition and was longtime submitted to polypharmacy without any improvement of the relentless course of this disease. The authors commented on the importance of a high index of suspicion to get an early correct diagnosis and prompt effective management that is indispensable to result in the best outcomes. The additional short comments on novel literature data aim to emphasize the exemplifying role of reported cases, mainly by enhancing the awareness of non-specialists and primary healthcare workers.
Navigating Barriers: Healthcare Anchor Institutions and Population Health Advancement
Authors: Wagner Daniel , Lagu Tara , Haywood Carol , Schafer Carolyn , Ackermann Ronald
Published: December 2024

Background: Many United States hospitals explicitly pursue “anchor missions” by committing to intentionally apply place-based economic power and human capital in partnership with the community. Little is known about how hospital-community partnerships are implemented or whether they impact social determinants of health (SDOH) and population health. We qualitatively analyzed healthcare institutions from a national network to understand barriers and facilitators while implementing hospital-community partnerships that aim to improve population health.
Methods: We used qualitative analysis of responses to open-ended items on a cross-sectional survey to explore how hospitals with anchor missions address SDOH. We administered the survey to healthcare systems participating in the Healthcare Anchor Network (HAN), a national network of hospitals with explicit goals to address SDOH and improve population health.
Results: Responses were from 16 organizations. Two themes emerged: 1) healthcare systems faced many demands (i.e., COVID-19, financial stability), which competed with prioritization of the anchor mission, and 2) senior leadership engagement was critical for impact of the anchor mission and efforts to address SDOH and population health. Strategies to engage leadership included peer networking and providing repetitive education on community health inequities to hospital leaders.
Conclusions: Although health systems show enthusiasm for population health, competing priorities often constrain anchor mission efforts to improve SDOH and population health outcomes. With external encouragement, such as changes to federal or state quality metrics reporting, payment incentives to address community health, or other policy changes, health systems will engage more with communities and be able to address SDOH.

Authors: Abling-Salupen Christine Anne G. , Ballena Constantino T.
Published: December 2024

This study investigated the speaking anxiety experienced by college seminarians in online English classes. The research aimed to describe the causes, effects, and coping strategies related to this anxiety. Using a hermeneutic phenomenological approach, data were collected through observations, in-depth interviews, and peer debriefing with nine purposively sampled participants. The analysis identified key themes such as fear of judgment, lack of confidence, and negative teaching styles as primary causes of anxiety. Manifestations included increased use of fillers, stuttering, and avoidance behaviors. Participants employed coping mechanisms like positive self-talk, regular practice, and prayer. The study concludes that supportive teaching practices significantly reduce speaking anxiety. Practically, the findings suggest that educators should create positive, interactive learning environments to alleviate anxiety and enhance language acquisition. Future research should explore speaking anxiety in diverse educational contexts and develop targeted interventions to mitigate this issue further.
Ruhsal Hastalıkların Manevi Tedavisine Sufilerin Yaklaşımları -İmam Gazzâlî Örneği
Authors: Akkaya Muhammed Veysel
Published: December 2024

İmam Gazzâlî, manevi hastalıkların tedavisi ile ilgili önemli fikirleriyle bu alana öncülük etmiş bir İslam alimidir. Gazzâlî’ye göre manevi hastalıklar, beden hastalıklarına benzer şekilde tedavi edilmelidir. Manevi hekim, hasta kişiye merhametle yaklaşmalı ve hastalığın köklerini ortadan kaldırmayı hedeflemelidir. Bu süreçte tevbe, sabır, şükür, tevekkül ve murakabe gibi manevi ilaçlar kullanılmalıdır. Manevi hastalıkların bedensel hastalıklardan daha çok olduğunu belirten Gazzâlî, manevi hastalıkların tedavisinde kişinin önce hastalıklarını fark etmesi ya da kendisine terapi ile fark ettirilmesi ardından bu hastalıklardan kurtulmak için çaba göstermesi gerektiğini belirtir. Allah ile olan ilişkinin bozulması ve düzensizliği psikolojik problemlerin temel kaynağıdır. Tevbe yani değişim sürecine girmek bu bozulmuş ilişkiyi düzeltmenin en önemli yoludur. Manevi tedavinin etkili olabilmesi için hastanın tedaviye inanması ve manevi rehberine güvenmesi gereklidir. Gazzâlî, ayrıca manevi tedavi için ilgili konuda yeterli bilgi donanımı olması gerektiğini ve bu konuda uzmanlaşmanın şart olduğunu belirtir. Modern psikolojiyle de ilişkilendirilebilecek bu yaklaşım, günümüzde tasavvufun psikoterapide alternatif bir yöntem olarak kullanılabileceğine dair umut verici bir gelişme olarak görülebilir.

Study of the epidemiological and serological aspects of toxoplasmosis in pregnant women and newborns treated in the city of Blumenau, Santa Catarina, Brazil
Authors: Sgrott Mateus Augusto , Dassoler Puff Stefano Giorgio , Zaniboni Siqueira Keila , Araújo Greinert Goulart Juliane
Published: December 2024

Toxoplasmosis is a disease caused by the protozoan parasite Toxoplasma gondii, with greater relevance in developing countries, capable of leading to serious complications in pregnant women and immunocompromised patients. Gestational toxoplasmosis, in most cases, occurs when a woman acquires a primary T. gondii infection during pregnancy, posing a risk of fetal sequelae or even fetal death, the disease being of compulsory notification in Brazil. The objectives of this study were to assess the epidemiological status of gestational and congenital toxoplasmosis in the city of Blumenau/SC and to increase knowledge about its prevalence in the region. To achieve this, an analysis of city data recorded in the Blumenau/SC Epidemiological Surveillance Service database was conducted between the years 2019 to 2021. During the study period, the city of Blumenau presented lower prevalence of gestational toxoplasmosis (2.93/1,000 pregnant women) and congenital toxoplasmosis (2.31/10,000 live births) than other regions of Brazil. Proper adherence to prenatal care and its screening protocols, as well as the early initiation of treatment, can result in a low incidence of congenital infections even in tropical areas with high seroprevalence. Rapid and accessible immunoglobulin G avidity testing allows for the exclusion of suspected cases without the need for invasive tests or unnecessary treatments. Education, on the other hand, plays a crucial role in disease prevention and should focus on encouraging proper prenatal care and providing adequate information about the disease. Finally, treatment adherence should be monitored and promoted.
KEY WORDS: Pregnancy complications; infectious; public health; toxoplasmosis, congenital; toxoplasmosis; epidemiology.
The public (mis)understanding of fiscal trade-offs – evidence from a survey experiment in Poland

Published: December 2024

Literatura na temat preferencji fiskalnych wskazuje, że obywatele często chcą jednocześnie wyższych wydatków państwa i niższych
podatków. Najnowsze badania dowodzą jednak, że być może taka obserwacja wynika z błędnie zaprojektowanych ankiet. Obywatele
odpowiednio poinformowani o kompromisach fiskalnych wyrażają znacznie bardziej spójne poglądy. W artykule włączamy się do
tej dyskusji. Za pomocą eksperymentu ankietowego, w którym wzięło udział 1800 dorosłych obywateli Polski, pokazujemy, że odpowiedzi
dotyczące pożądanej roli państwa różnią się znacznie w zależności od tego, czy pytanie zawiera odniesienie do podatków.
Wykorzystując analizę regresji identyfikujemy płeć, poziom wykształcenia i indywidualny dochód jako istotne determinanty skali

THE CRISIS OF SMALL AND MEDIUM BUSINESS SUBJECTS AND ITS PREVENTION IN THE POST-PANDEMIC PERIOD IN GEORGIA
Authors: Giorgi Katamadze
Published: December 2024

Small and medium-sized businesses in Georgia have been the subject of extensive research for decades since the transition to a market economy. However, despite the huge number of studies, there is no clear definition of the term – small and medium-sized business. In addition to the comprehensive analysis of business subjects’ activities, this work offers a new, research-based definition of the term.

Disruptions in the business operating cycle, force-majeure, crises and the cases of complete paralysis are the subject of our complex research, which frequently appears to be a variety of business cycle stress tests and represents valuable scientific material for future research.

The Covid-19 pandemic has been and continues to be the most expensive, demanding and long-lasting stress test of contemporary world, which a huge number of business entities have struggled to overcome, and many of them are still grappling with this challenge.

During and after the pandemic period, Georgian government, international organizations, financial institutions, public organizations and others played critical roles in ensuring the smooth business operations. The relevance of our research stems from this complex, diverse anti-crisis measures in various domains, as well as the study of approaches, being entirely based on empirical research using interdisciplinary methodology.

The research was supported by Shota Rustaveli National Science Foundation of Georgia, (SRNSFG) Grant number YS-22-548; project title –“The Crisis of Small and Medium Business Subjects and its Prevention in the Post-Pandemic Period in Georgia“.

Authors: B. Katerengabo, , C. Gakuu, , H. Kidombo,
Published: December 2024

The study assessed the influence of households’ involvement in the implementation of the Monitoring and Evaluation (M&E) plan on the performance of the Tanzania Conditional Cash Transfer Project (CCTP). The study used the mixed method whereby the sample size was 400 heads of households while purposive sampling enabled to obtain 8 Village Committees and 8 Monitoring Officers. Quantitative data was analysed using Pearson’s correlation and regression model while qualitative data was analysed using content analysis. The study established a significant influence between households’ involvement in the implementation of the M&E plan (t= 8.472, p-value =.000) on the performance of the Tanzania CCTP. It was recommended therefore that the Tanzania CCTP M&E policy should be reviewed to ensure it is vital for households’ involvement in the M&E cycle. The research recommended further study on the organizational practice and level of use of M&E information for further improving performance.
