Published: January 2025

Bu çalışma, birçok partinin ve adayın rekabet ettiği ve seçmen katılımının yüksek olduğu çok partili bir demokrasi olan Türkiye’de Z kuşağı seçmenlerinin seçim kampanyalarından etkilenme durumlarını incelemekle birlikte, daha spesifik olarak seçim kampanyalarının Z kuşağı seçmenlerinin siyasal katılımını, oy verme davranışını ve aday tercihini ne yönde etkilediğini araştırmaktadır. Araştırma, ilişkisel tarama modeli ve keşfedici yaklaşım olmak üzere iki ana yöntem bağlamında yapılandırılmış; 700 katılımcıdan elde edilen veriler tanımlayıcı istatistikler ve parametrik testler ile analiz edilmiştir. Bulgular, seçim kampanyalarının seçmenlerin siyasi katılımını ve oy kullanma olasılığını artırdığını, aday tercihi üzerinde ise çok az etkisi olduğunu ortaya koymaktadır. Ayrıca seçim kampanyalarının politik okuryazarlık düzeyi yüksek olan seçmenlerin aday kararsızlığını azalttığını ve seçmenlerin politik okuryazarlık yeterlilikleri arttıkça seçim kampanyaları aracılığıyla siyasal katılıma yönelme oranlarının artacağı tespit edilmiştir. Seçmenlerin seçim kampanyalarını takip etme eğiliminde olduğu belirlense de seçim kampanyalarının tespit edilen etkilerinin sınırlı olduğu görülmüştür. Bu etkilerin ilk kez oy kullanan seçmenler bazında da benzer olduğu belirlenmiştir. Araştırma seçmenlerin en etkili bulduğu seçim kampanyaları ve kampanyalar dahilindeki siyasal reklamlara dair sonuçlar ile seçmenlerin Türkiye’de yürütülen seçim kampanyalarının başarısını ve gerekliliğini nasıl değerlendirdiğine yönelik detaylı bulgular da ortaya koymuştur.
CONSUMERS' SELF-IDENTITY PERSPECTIVES ON BRAND PREFERENCES AND BOYCOTT BEHAVIOUR: AN APPLICATION OF A BLIND TASTE TEST
Authors: Şehirli Mustafa
Published: January 2025

This research aims to reveal the relationship between the self-identity of modern individuals, who seek to find themselves by consuming in a consumer society, and their consumption preferences and behaviours through boycott behaviour. For this purpose, a study was conducted in 2024 with 322 university students in Istanbul, utilizing a blind taste test involving two products (cola and coffee) from one global and one local brand (Pepsi/Cola Turka and Starbucks/Kahve Dünyası) regarding the boycott against brands supporting Israel. According to the research findings, the participation rate in the boycott is 57%. Regardless of participation in the boycott, no statistically significant difference was found in brand preferences during the blind test among all participants. However, it was revealed that the preferences for products related to Starbucks significantly decreased among participants who supported the boycott. Although not statistically significant, a decrease was also observed for Pepsi. The primary reasons affecting participation in the boycott are emotional factors, such as a reaction to crimes against humanity and support for the oppressed. Those who did not participate in the boycott expressed their belief that the boycott or their participation would have no impact. No significant relationship was identified between the phenomenon of self-identity, which is the research's main subject, consumer preferences (participation in the boycott), and indirectly, brand preferences. The self-identity preferences of participants and non-participants in the boycott were similar, with the most commonly expressed identity definition being "human."

Authors: Brooks Michelle M. , Lawal Wasiu
Published: January 2025

The development of standards and guidelines for undergraduate chemistry programs across the globe can ensure that students and faculty have the facilities, curriculum, skills, and infrastructure to support chemistry education. The American Chemical Society began its exploration of standards in the United State in the 1930s culminating in the ACS Approval Program, which currently includes over 700 programs in the United States. In 2019, ACS embarked on the development of an ACS Recognition Program for programs worldwide. The development of guidelines and standards for these related, but not identical, programs is based on the core principles of the ACS and the needs of the broader chemistry education community. It involved an iterative process that included contributions from chemistry professionals, educators, employers, and other stakeholders, with feedback from the broader academic community. The goal of these guidelines and the approval and recognition programs is to ensure that students have an engaged faculty, a safe and inviting space to learn, access to modern instrumentation for teaching and research, a safe, inclusive, and equitable environment in which to learn, and the content knowledge and skills needed for success as a chemical professional.
Identification of hub genes and pathways in mouse with cold exposure
Authors: Wang Xu , Hu Hongbo , Zhang Ying
Published: January 2025

Background

Cold exposure is linked to numerous diseases, yet the changes in key genes and pathways in mice under cold exposure remain unexplored. Understanding these alterations could offer insights into the mechanisms of cold resistance and contribute valuable ideas for treating cold-related diseases.

Methods

The dataset GSE148361 was obtained from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were identified using the “limma” package in R software. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed on DEGs. The STRING (Search Tool for the Retrieval of Interacting Genes) database was used to construct a protein-protein interaction (PPI) network. Additionally, gene set enrichment analysis (GSEA) was conducted to identify pathways associated with key genes. miRNAs and upstream transcription factors (TFs) were predicted using the miRNet database.

Results

A total of 208 DEGs were identified, with 137 upregulated and 71 downregulated. In biological processes, DEGs were enriched in nucleotide and purine-containing compound metabolism. For cellular components, DEGs were involved in condensed chromosomes and mitochondrial protein complexes. In molecular functions, proton transmembrane transporter activity was enriched. KEGG pathway analysis showed significant enrichment in biosynthesis of unsaturated fatty acids, fatty acids, and pyruvate metabolism. From the PPI network, 12 hub genes were identified using MCODE. Four hub genes (Col3a1, fi203, Rtp4, Vcan) demonstrated similar trends in a validation set (GSE110420) and were significantly differentially expressed. GSEA analysis indicated that these four genes were enriched in pathways such as ECM-receptor interaction and cytokinecytokine receptor interaction. The hub gene network included 93 miRNAs and one TF

Conclusion

This study identified four hub genes as potential diagnostic biomarkers for cold exposure, providing insights for further research on the effects of cold on gene expression and disease.
The function and effect on prognosis of ANXA2 in gastric cancer peritoneal metastasis patients in cold region
Authors: Jin Shiyang , Liang Longxu , Huang Xiaoyi , Wang Kuan
Published: January 2025

Objective

Heilongjiang Province is part of the northern cold areas of China, where gastric cancer is one of the most common gastrointestinal malignancies. Peritoneal metastases (PM) are the leading cause of mortality among patients. This study conducted bioinformatics and basic research on the gene ANXA2 (Annexin A2), which may influence the prognosis of patients.

Methods

Genome sequencing was performed on patients from Heilongjiang to identify potential genes impacting survival time. The function of ANXA2 in gastric cancer was analyzed using multiple bioinformatics databases, focusing on its pathways and mechanisms. ANXA2-knockout gastric cancer cell lines were constructed, and in vitro assays, including CCK-8, flow cytometry, scratch, and Transwell experiments, were conducted. A nude mouse tumorigenesis model was also developed to analyze in vivo effects.

Results

ANXA2 was found to be expressed at higher levels in gastric cancer tissue than in normal gastric tissue, and its mRNA levels were associated with short overall survival (OS). Enrichment analysis indicated that ANXA2 is primarily localized on the cell membrane and primarily influences the PI3K-AKT signaling pathway. Cytological experiments demonstrated that knockdown of ANXA2 suppresses the growth and migration of gastric carcinoma cells, an effect that was also observed in vivo.

Conclusions

ANXA2 is essential for gastric cancer growth and may represent a potential risk factor affecting the survival probability of patients in cold regions.

Objective

To evaluate the clinical efficacy of combining arthroscopic patellar denervation with microfracture in the treatment of patellofemoral arthritis under cold weather conditions.

Methods

A total of 134 patients with patellofemoral arthritis who underwent treatment between June 2019 and June 2021 were included in this study. Patients were randomly divided into two groups: the control group, which received standard arthroscopic debridement and conventional therapy, and the study group, which underwent additional peripatellar denervation and microfracture procedures. Clinical outcomes, including Tegner scores, hospital for special surgery (HSS) scores, and treatment-related adverse events, were evaluated and compared between the two groups.

Results

The study group achieved a significantly higher excellent treatment rate (95.52%, 64/67) compared to the control group. Posttreatment Tegner scores (5.48 ± 1.86) and HSS scores (86.37 ± 11.25) were also significantly better in the study group than in the control group. Furthermore, the incidence of adverse reactions was lower in the study group (4.48%, 3/67), with statistically significant differences observed (P< 0.05).

Conclusions

Arthroscopic patellar denervation combined with microfracture markedly improves clinical outcomes, including Tegner and HSS scores, in the treatment of patellofemoral arthritis, particularly under cold weather conditions. The procedure is effective and safe, supporting its broader clinical application.

Authors: Prajapati Jayeshkumar C. , Pankhaniya Shyamkumar A. , Maradia Kishor G.
Published: January 2025

Radio over fiber is upcoming and maturing technology in terms of security, reliability, and coverage for long-distance optical-wireless communication systems. The nonlinear behavior and dispersive nature of optical channels are performance restrictive factors limiting the long reach in such systems. Along with enhancing channel capacity and bandwidth for radio signals over a long distance, the use of OFDM-based such systems can overcome various performance degrading effects like phase modulation, electrical power attenuation, chromatic dispersion, and multipath fading. Here, we propose our design of an 8 channels WDM RoF PON system using the OFDM scheme. Performance analysis is carried out in terms of performance comparison for various modulation schemes like 8, 16, 128, 256, and 512 QAM levels applied on information for long transmission reach of a system up to 500Kms. 8 channels WDM system model is developed to analyze the performance at a higher data rate. System performance is evaluated with Q factor and EVM level parameters of recovered signals at various transmission distances.

Published: January 2025

Nanophotonics, which explores significant light–matter interactions at the nanoscale, has facilitated significant advancements across numerous research fields. A key objective in this area is the design of ultra-compact, high-performance nanophotonic devices to pave the way for next-generation photonics. While conventional brute-force, intuition-based forward design methods have produced successful nanophotonic solutions over the past several decades, recent developments in optimization methods and artificial intelligence offer new potential to expand these capabilities. In this review, we delve into the latest progress in the inverse design of nanophotonic devices, where AI and optimization methods are leveraged to automate and enhance the design process. We discuss representative methods commonly employed in nanophotonic design, including various meta-heuristic algorithms such as trajectory-based, evolutionary, and swarm-based approaches, in addition to adjoint-based optimization. Furthermore, we explore state-of-the-art deep learning techniques, involving discriminative models, generative models, and reinforcement learning. We also introduce and categorize several notable inverse-designed nanophotonic devices and their respective design methodologies. Additionally, we summarize the open-source inverse design tools and commercial foundries. Finally, we provide our perspectives on the current challenges of inverse design, while offering insights into future directions that could further advance this rapidly evolving field.
Curcumin-encapsulated Pluronic micelles in chitosan/PEO nanofibers: a controlled release strategy for wound healing applications
Authors: Kharat Zahra , Azarnia Maliheh , Ranjbar Parviz Rashidi , Kabiri Mahboubeh
Published: January 2025

Chitosan-based nanofibers loaded with therapeutic agents are promising for wound treatment but loading hydrophobic compounds remains challenging. To address the limitations of curcumin incorporation in chitosan/polyethylene oxide (CS/PEO) nanofibers, we developed a novel Pluronic-based micelle to encapsulate curcumin, followed by the incorporation of zinc oxide nanoparticles (ZnO-NPs) as an antibacterial agent to improve the performance of the wound dressings’ materials. We successfully fabricated CS/PEO scaffolds via electrospinning, incorporating curcumin-loaded micelles and synthesized ZnO-NPs. Comprehensive morphology characterization was performed using SEM, and the presence of ZnO-NPs and curcumin was verified by EDX and FT-IR spectroscopy. The developed nanofibers showed a slower release profile, with approximately 80 % of curcumin released into the aqueous medium within 24 h and appearing to progress to a steady state by five days. Notably, the nanofiber mats exhibited antibacterial activity against the Gram-positive bacterium Staphylococcus aureus, and supported fibroblast proliferation and attachment, indicating excellent biocompatibility. These findings suggest that the developed nanofiber scaffold, characterized by its controlled drug release, potent antibacterial properties, and biocompatibility, holds promise as an advanced wound dressing material.
A vizuális elemek tartalmának szerepe az online felsőoktatási marketingben - Feltáró kutatás a nemzetközi hallgatók körében
Authors: Kéri Anita
Published: January 2025

A TANULMÁNY CÉLJA
A tanulmány célja, hogy feltárja, milyen online megjelenő képi marketingtartalmakat érdemes használnia a felsőoktatási intézményeknek a jelenlegi külföldi hallgatóik hatékonyabb megszólítása érdekében a különböző vizuális elemek megjelenítésén keresztül, különös tekintettel az intézmények honlap felületeire.
MÓDSZERTAN
A szekunder szakirodalmi feltárás során az online felsőoktatási marketing sajátosságai és a szemkamerás kutatási módszertan kerülnek áttekintésre. A kutatási cél elérésének érdekében primer kutatásként szemmozgáskövetéses adatfelvétel, valamint RTA (Retrospective Think Aloud) interjúk készültek a vizsgált egyetem külföldi hallgatóival. A szemkamerás kutatás esetén az alanyok a vizsgált egyetem honlapjának képeit láthatták, melyet követően RTA interjúk segítettek a tartalom visszaidézésében. A szemkamerás ingeranyagok két csoportba sorolhatók. Az egyik képtípuson a hallgatók saját társaikat láthatták egyetemi környezetben és egyetemi eseményen, míg a másik képtípuson ismeretlen emberekkel készített, úgynevezett „stock” fotók találhatók. A képek mellett megjelenített üzenetek minden esetben a külföldi hallgatók számára releváns és hasznos információkat tartalmaztak.
LEGFONTOSABB EREDMÉNYEK
A kvantitatív és kvalitatív adatfelvétel eredményei azt mutatják, hogy a vizsgált külföldi hallgatók, habár kevesebb figyelmet szentelnek azoknak a tartalmaknak, melyeken ismerős arcokat vélnek felfedezni, mint a „stock” képeknek, mégis jobban emlékeznek azokra az információkra, melyek ismerős arcokkal tarkított képeken jelennek meg.
GYAKORLATI JAVASLATOK
A kutatás eredményei hatékonyabb üzenetátadási formákat és célzottabb felsőoktatási marketinget eredményeznek, ugyanis kiderült, hogy az alanyok számára az ismerős arcok megjelenítése vonzóbb, a vonatkozó információkat hatékonyabban megjegyzik szemben a fizetett képekkel. A kutatás fontos üzenete a vizsgált intézmény felsőoktatási marketinges kollégáinak, hogy olyan vizuális elemeket alkalmazzanak a gyakorlatban, melyek saját eseményeik és saját hallgatóik ábrázolása mellett adnak át fontos információkat és szólítják meg a célcsoportot, hiszen az üzenetátadás így hatékonyabbnak bizonyul a „stock” fotókkal szemben.

Optimization of Mechanics and Rheology of Grouting Materials Based on Carbon Nanotubes
Authors: Liu Jingyi , Wang Yongwei , Gao Ni , Liu Kaiping , Wen Jiuran
Published: January 2025

As one of the pillar industries of the national economy, the construction industry has increasingly high requirements for the performance of grouting materials. To overcome the shortcomings of low tensile strength and poor toughness of grouting materials, this study selects raw materials such as quartz powder and completes the ultra-fine grouting material ratio through the theory of slurry filling and wrapping. Carbon nanotubes are used to improve the performance of the grouting material. The results indicated that in mechanical performance testing, as the content of carbon nanotubes increased, the strength first increased and then decreased. Among them, when the dosage was 0.1–0.2 %, the flexural strength and compressive strength had the highest increase of 33.62 % and 29.30 %, respectively, with the best reinforcement effect. In terms of rheological properties, the grouting materials were adversely affected by dispersants. The addition of carbon nanotubes increased its yield stress and plastic viscosity with increasing dosage. However, at the appropriate dosage, the normal flow performance and compressive strength were effectively guaranteed. As the diameter of carbon nanotubes increased, the impact of carbon nanotubes on the viscosity of the grouting material decreased. Furthermore, the effect of diameter changes was more pronounced. As a result, carbon nanotubes have optimized the mechanical properties and rheological properties of the grouting material, providing a reliable reference for engineering applications.
Metabolic Analysis of the Mode of Action and Mode of Resistance for Novobiocin in Staphylococcus aureus
Authors: Xie Weile , Luo Dan , Wang Zhe
Published: January 2025

Objective:

Methicillin resistant Staphylococcus aureus (MRSA) and Vancomycin resistant Staphylococcus aureus (VRSA) are critical pathogens identified by the WHO for their significant drug resistance. Targeting of bacterial gyrase, specifically the gyrB subunit, is a promising approach because of this enzyme’s essential role in bacterial DNA replication and its absence in higher eukaryotes. However, understanding of the mode of action of gyrB inhibitors remains largely incomplete. This study explored the resistance mechanisms of Staphylococcus aureus (S. aureus) to novobiocin, a gyrB inhibitor.

Methods:

Through adaptive laboratory evolution, key resistance mutations (in gyrB, potB, and fpgS) in S. aureus were identified after repeated exposure to novobiocin. Further metabolomic analysis revealed the function of the major mutation (in gyrB) in relation to the potential mechanism through which S. aureus responds to novobiocin.

Results:

Through whole genome sequencing, three mutations of S. aureus in gyrB, potB, and fpgS were identified. The gyrB mutation was the primary driver of resistance, and was associated with changes in growth, survival under surface and oxidative stress, cell wall permeability, and coagulation functions. Metabolomic analysis demonstrated compensatory metabolic adjustments affecting protein synthesis and DNA replication in the resistant strain.

Conclusions:

These findings provide insights into the complex resistance mechanisms of S. aureus to novobiocin and highlight the metabolic costs associated with gyrB mutations, thereby potentially informing future antibacterial strategy development.
HYBRID 3D WOVEN STRUCTURES FOR CONCRETE REINFORCEMENT UNDER IMPACT LOADING PART 1: DEVELOPMENT OF A BI-AXIAL CORE DESIGN
Authors: Ortega Arbulu Juan Daniel , Nuss Dominik , Cherif Chokri
Published: January 2025

Steel reinforced concrete (RC) is extensively used in the construction industry due to its high strength, durability, and versatility. Nonetheless, its resilience under dynamic loads, such as impact, remains particularly low. The research training group DFG GRK 2250 aims to significantly improve the impact energy absorption of existing infrastructures by applying thin layers of an innovative strengthening material composed of a strain hardening cementitious composite and a novel textile reinforcement. This paper investigated methods for manufacturing 3D hybrid woven fabrics with a core incorporating spatial elements in both the weft and warp directions, based on a bi-axial core design. The challenges associated with shaping spatial elements before and during the weaving process were discussed, with the latter proving to be the optimal choice when combined with carbon fiber towpregs. After developing the structural design, selecting the materials for each element, and establishing the fabric binding pattern, a demonstrator was successfully produced using a modified rapier weaving machine.
STEM Learning with a Simple Hydraulic Pump Project to Improve Student Communication and Collaboration Skills
Authors: Amri Muhammad Fahriza , Prima Eka Cahya , Winarno Nanang , Mohamad Maslawati
Published: January 2025

To succeed in today's era, a person must possess 21st-century skills, which include communication and collaboration. With a Simple Hydraulic Pump project, this study aims to enhance students' communication and collaboration skills through STEM learning at the junior high school level. This quantitative study applied a quasi-experimental approach with a pretest-posttest control group research design. The participants are 38 out of 228 8th-grade students in two junior high schools in Bandung, Indonesia. Statistical analyses using the Wilcoxon Signed Rank tests were done on the data obtained through pretests and posttests. The results indicate a non-significant gain in communication skills of students in the experimental group compared to the control group, with a significance value of 0.67 (sig. >0.05), meaning that there is a non-significant difference between pretest and posttest results. Meanwhile, the collaboration skills of students in the experimental group increased significantly compared to the control group, with a significance value of 0.03 (sig. <0.05), indicating a significant difference between the pretest and posttest results. Using Cohen’s d, it is evident that students’ collaboration skills experience a medium increase (r=0.22). Furthermore, students’ communication and collaboration skills were measured using the Performance Assessment Rubric. The results demonstrate that STEM learning using a simple hydraulic pump project can enhance students’ collaboration skills but not their communication skills. This implies that while STEM learning helps students improve their collaboration skills, other methods are needed to assist them in developing their communication skills.

Periscope of Ideas Selective Criteria for the Application of Restorative Justice in Corruption Crimes
Authors: Wangga Maria Silvya E. , Ahmad Nadzriah , Puluhulawa Jufryanto , Swarianata Vifi
Published: January 2025

This article applies the theory of restorative justice to the analysis of state losses resulting from corrupt activities. This study employs socio-legal research, which is a type of normative legal research that is dependent on values and facts. The study's findings revealed that two (2) points of view are based on the fundamental notion that restorative justice can compensate the state for damages incurred through acts of corruption. First, in order to make up for the losses sustained by the state as a result of corrupt criminal acts, law enforcement must be centered around the idea of restorative justice. Secondly, the fact that the Constitutional Court's ruling Number 25-PUU-XIV-2016 eliminated the word "may" from Article 2 paragraph (1) and Article 3 of Law Number 20 Year 2001 in combination with Law Number 31 Year 1999 for the Eradication of Corruption remains a reality. In order to ensure that substantive justice in the application of restorative justice does not clash with current laws and regulations and is administered with chosen criteria, the A quo ruling nullifies Article 4 of the Corruption Crime Eradication Law.

Published: January 2025

The 5E instructional model is an inquiry-based learning approach. This model is an effective approach to improving student learning outcomes. It is currently implemented using virtual experiments or a combination of real and virtual experiments. This research aims to investigate the effects of using a real laboratory (RL), a virtual laboratory (VL), and a combination of RL and VL based on the 5E learning cycle model on student learning outcomes in the subject of electricity. A quasi-experimental design involving pre-test and post-test comparisons between groups was employed in this research. The research sample consisted of 166 first-year students from a rural middle school. Students were divided by reasoned choice into three groups. The first group (RL) included 58 students (using real laboratory activities), the second group (VL) included 56 students (using virtual laboratory activities), and the third group (RL+VL) included 52 students (using both real and virtual laboratory activities). The research was conducted during the second semester of the 2022 school year. Data were analyzed using a paired-sample t-test, one-way ANOVA, and N-Gain. The results reveal that the combined use of real and virtual lab activities results in a more substantial improvement in student learning outcomes than using real or virtual labs alone.
Levothyroxine malabsorption following sleeve gastrectomy
Authors: Gruneisen Elodie , Yang Ji Wei , Pasqua Melissa-Rosina
Published: January 2025

Oral levothyroxine (LT4) is prescribed worldwide for hypothyroidism. Bariatric surgery for patients with obesity has shown a substantial, long-term weight loss and considerable improvement of obesity-related diseases. LT4 malabsorption represents a significant cause of refractory hypothyroidism, well known after malabsorptive bariatric surgery such as Roux-en-Y gastric bypass. However, few studies have shown an increase in oral LT4 needed after sleeve gastrectomy. We present a 47-year-old woman with class III obesity and a history of papillary thyroid cancer, with an excellent biochemical and structural response after total thyroidectomy and radioactive iodine. She underwent sleeve gastrectomy 3 years later and developed refractory hypothyroidism despite taking high doses of oral LT4 and ensuring compliance. The T4 absorption test confirmed gastrointestinal LT4 malabsorption. She was initiated on intramuscular LT4 and oral T3 (liothyronine) with improving symptoms and levels of thyroid-stimulating hormone.

Learning points

Monitoring thyroid function tests is essential after bariatric surgery, including sleeve gastrectomy.

Oral LT4 malabsorption should be considered in cases of refractory hypothyroidism.

The T4 absorption test is a useful tool for distinguishing true malabsorption from pseudo-malabsorption.

Decreased LT4 absorption after bariatric surgery might be explained by higher gastric pH and reduced stomach volume (impaired dissolution) and by interference with food, vitamin/mineral supplements or other drugs.

When LT4 malabsorption is confirmed, a trial of other oral formulations (LT4 tablet crushed, soft gel or liquid preparation) or parenteral administrations is suggested.

Полученные данные о качественном и количественном составе летнего фито- и зоопланктона двух озер п-ова Таймыр свидетельствуют о более высоком трофическом статусе водоема, испытывающего нагрузку со стороны гидрофильных птиц. По сравнению с фоновым водоемом здесь зарегистрированы статистически значимо большие численность фитопланктона (134,6 ± 16,3 тыс. кл./л против 60,4 ± 11,8 тыс. кл./л), биомасса зоопланктона (349,0 ± 170,2 мг/л против 64,5 ± 19,5 мг/л), биомасса коловраток (15,6 ± 3,5 мг/л против 1,6 ± 0,4 мг/л) и их доминирование, а также индекс сапробности (1,71 ± 0,09 против 1,48 ± 0,06). Одновременно выявлены специфические черты организации сообществ этого водоема - более высокое видовое богатство фито- и зоопланктона; отсутствие в составе фитопланктона Cyanobacteriaи статистически значимо более высокие численность Bacillariophyta (80,7 ± 11,8 тыс. кл./л против 31,7 ± 6,5 тыс. кл./л), число видов (4 против 2) и биомасса (326,6 мг/л против 60,6 ± 18,8 мг/л) веслоногих ракообразных, что может определяться особенностями реакции гидробионтов на продукты жизнедеятельности птиц. Это позволяет говорить о перспективах гуанотрофикации для повышения трофического статуса водоемов без значимого ухудшения качества среды и биологического разнообразия сообществ гидробионтов.

The data obtained on the qualitative and quantitative composition of summer phyto- and zooplankton of two lakes of the Taimyr Peninsula indicate a higher trophic status of the water body, which is under pressure from hydrophilic birds. Compared to the background water body, statistically significantly higher phytoplankton abundance (134.6 ± 16.3 thousand cells/l vs. 60.4 ± 11.8 thousand cells/l), zooplankton biomass (134.6 ± 16.3 thousand cells/l vs. 60.4 ± 11.8 thousand cells/l), zooplankton biomass (349.0 ± 170.2 mg/l vs. 64.5 ± 19.5 mg/l), rotifer biomass (15.6 ± 3.5 mg/l vs. 1.6 ± 0.4 mg/l) and their dominance, as well as saprobic index (1.71 ± 0.09 vs. 1.48 ± 0.06). At the same time, specific features of community organization were revealed - higher species richness of phyto- and zooplankton; absence of Cyanobacteria in phytoplankton composition and statistically significantly higher abundance of Bacillariophyta (80.7 ± 11.8 thousand kl./l vs. 31.7 ± 6.5 thousand kl./l), number of species (4 vs. 2) and biomass (326.6 mg/l vs. 60.6 ± 18.8 mg/l) of paddle-bearing crustaceans, which may be determined by the peculiarities of hydrobionts reaction to the products of bird activity. This allows us to speak about the prospects of guanotrophication to improve the trophic status of water bodies without significant deterioration of environmental quality and biodiversity of hydrobiont communities.

Collaborative writing is a complex task that involves diverse regulatory processes. In this case study we address the resolution of Problem-Based Learning through a report written collaboratively. Ten students from the Human Biology degree and their tutor took part. We collected data inside the classroom (the writing assignment, the assessment rubric, and audio recordings of 3 tutorials) and data outside the classroom (screen recordings of the students’ activity on their computers, the team’s WhatsApp group conversation, the final text of the written work, a focus group recording and the evaluative comments of the marking teachers). The results indicate that the processes of self-regulation and socially shared regulation are the most developed. Participants demonstrate control and autonomy in carrying out individual and group activities. On the other hand, co-regulation is less frequent, as the teacher’s mediation, the writing assignment, and the evaluation instruments could be more specific in relation to the task to be carried out. Consequently, it is necessary to generate gender-specific mediation and evaluation tools to improve collaboration among students when writing.

Authors: Castro Morgado Rocío , Anaya Ramírez Verónica
Published: January 2025

Analisamos tutoriais virtuais para apoiar a melhoria das competências de comunicação escrita em cursos massivos e transversais em Humanidades, destinados a estudantes que ingressam numa universidade privada na Lima Metropolitana durante 2020, ano em que se iniciou o confinamento social pela COVID-19. A abordagem baseia-se em fontes primárias; é de base populacional, quantitativa e de âmbito exploratório. O objetivo é demonstrar que, apesar do contexto adverso, os utilizadores melhoraram a sua proficiência em competências de comunicação escrita. Como conclusão, identifica-se que os alunos que recorreram às tutorias obtiveram aprovação nas disciplinas numa proporção superior à dos que não recorreram ao serviço, o que teve um impacto positivo nos indicadores de satisfação dos alunos e na diminuição do abandono escolar.

Published: January 2025

Intercultural competence represents an essential part of a translator/interpreter’s training, as it enables effective communication between languages and cultures. This paper is aimed at measuring the intercultural competence of Translation and Interpreting students at a Peruvian university in three dimensions: theoretical knowledge, operational knowledge and cultural sensitivity. For this purpose, descriptive research was conducted and 3 instruments were elaborated and applied to a sample of 58 students of the Translation and Interpreting program: students of the sixth and seventh semester who begin the translation and interpreting workshops, and students of the tenth semester who are about to graduate. The results show that students had high scores in cultural sensitivity, medium-high scores in theoretical knowledge and low scores in operational knowledge, where there were important differences in the ability to identify cultural references and verbalize translation strategies. Therefore, it might be concluded that students are in the process of acquiring intercultural competence and, enhancing their learning in this area requires textual exercises that expose them to diverse cultural manifestations from the dominant and minority cultures.
Prescription Stimulant Dispensing to US Children: 2017–2023
Authors: He Sijia , Esteban McCabe Sean , Conti Rena M. , Volerman Anna , Chua Kao-Ping
Published: January 2025

OBJECTIVE

To evaluate changes in prescription stimulant dispensing to children aged 5 to 17 years associated with the COVID-19 pandemic and the shortage of immediate-release mixed amphetamine salts (Adderall), which was announced in October 2022.

METHODS

We analyzed the 2017 to 2023 IQVIA Longitudinal Prescription Database, which captures 92% of US prescriptions. Using an interrupted time series design, we evaluated level and slope changes in the monthly stimulant-dispensing rate (number of children with stimulant dispensing per 100 000 children) in March 2020 and October 2022.

RESULTS

In March 2020, the monthly stimulant-dispensing rate to children declined −454.9 children per 100 000 (95% CI, −572.6 to −337.2), an 18.8% decrease relative to January 2017. After March 2020, this rate increased to 12.7 children per 100 000 per month (95% CI, 6.6–18.8). In October 2022, there was no level change (−39.7 children per 100 000; 95% CI, −189.9 to 110.5) or slope change (−12.1 children per 100 000 per month; 95% CI, −27.5 to 3.3), although estimates were negative. During October 2022, there was a level decrease in the monthly dispensing rate for immediate-release mixed amphetamine salts and a level increase in the monthly dispensing rate for dexmethylphenidate.

CONCLUSIONS

Stimulant dispensing to children declined after the pandemic began. Dispensing may also have declined after October 2022, but estimates were not significant, partly because decreased dispensing of immediate-release mixed amphetamine salts was offset by increased dispensing of other stimulants. Findings suggest the shortage may have prompted children to switch to alternative stimulants. Future research should evaluate whether any switches led to adverse events.
Peama Sumapaz, ¿un modelo de educación para el desarrollo?
Authors: León Rojas Andrés Leonardo
Published: January 2025

Este artículo pretende hacer una valoración pedagógica general del proceso del Programa Especial de Admisión y Movilidad Académica (Peama) Sumapaz, teniendo en cuenta sus intencionalidades, metodologías, logros, limitaciones y perspectivas.

Se aborda inicialmente el concepto hegemónico de desarrollo, la particularidad de éste en el ámbito universitario como una forma de colonialidad del saber y algunas alternativas desde el sur. Luego, se hace un pequeño recuento de lo que es el Peama en general y un recorrido histórico del Peama Sumapaz. Después se analiza el Peama Sumapaz a la luz del concepto de desarrollo, para finalmente concluir y sugerir una serie de recomendaciones.

A partir de los resultados cualitativos obtenidos a partir de revisión bibliográfica, documentación, observación participativa y entrevistas, se concluye que el Peama Sumapaz no encaja dentro del modelo de desarrollo hegemónico por razones epistémicas, económicas y pedagógicas, pero tampoco se puede considerar que entre en ruptura completa con estos planteamientos.

Comemorando a ditadura, celebrando o capital: uma interpretação do Monumento a Castelo Branco como uma “memória do capitalismo” (Porto Alegre, Brasil, 1979)
Authors: Silveira-Bauer Caroline
Published: January 2025

o envolvimento de empresários nas ditaduras implementadas no Cone Sul na América Latina nos anos 1960 e 1970 vem sendo pesquisado multidisciplinarmente, com predileção para os temas da colaboração e do financiamento com os órgãos da repressão. Iniciativas do campo da justiça de transição têm reconhecido a responsabilidade empresarial por essas violações de direitos humanos, contribuindo para a elaboração de medidas de reparação e políticas de memória. Este artigo propõe um estudo sobre um tipo específico de cumplicidade entre o capital e o Estado: a construção de homenagens às ditaduras nos espaços públicos. Mobilizando um arcabouço teórico do qual se destacam as categorias de dádiva e contra-dádiva, e utilizando documentos oficiais e periódicos de diversas procedências, analisa o Monumento a Castelo Branco, construído em Porto Alegre, capital do estado do Rio Grande do Sul, Brasil, em 1979, por iniciativa de um grupo de empresários sul-rio-grandenses. Argumenta-se que o monumento pode ser considerado uma “memória do capitalismo”, porque a homenagem selou relações entre o empresariado e a ditadura durante a conjuntura de transição política. Desta forma, explica-se a importância da ressignificação dessas homenagens e de repensar as formas de reparação e responsabilização no escopo da justiça de transição
