Published: February 2025

Metacognitive strategies are techniques or approaches used to help students understand and control their own thinking processes, including the abilities to plan, monitor, and evaluate their learning. In the context of Problem Based Learning (PBL), these strategies assist students not only in deeply understanding the material but also in enhancing their ability to organize and reflect on how they solve problems independently. This article employs a Systematic Literature Review (SLR) method to identify and analyze the fundamental concepts of metacognitive strategies, their roles in PBL, and effective implementation steps in the classroom. Key components discussed include task planning techniques, monitoring of understanding, and reflection on outcomes. The findings indicate that the application of metacognitive strategies within PBL can strengthen students' learning independence, improve critical thinking skills, and foster their confidence in tackling complex problems. Furthermore, the implementation of these strategies encourages students to be more active and reflective in their learning processes, contributing to a deeper and more sustainable understanding of the material.

Published: February 2025

Introduction: Previous research has not explored features and behavior change techniques (BCTs) in physical activity (PA) promotion interventions among adolescents, including mobile health (mHealth) applications. Purpose: This study aims to conduct a narrative literature review of adolescent PA promotion apps, examining their theoretical foundations, key BCTs, primary features, and their influence on PA adherence and maintenance. Methods: The review includes peer-reviewed studies published from 2012 to December 2024, employing qualitative and quantitative methodologies. Included studies examined healthy adolescents, focusing on PA app features and their relationship to PA promotion. Results: A total of twenty-one studies were analyzed: ten reviews, eight qualitative studies, and three app quality assessments. Findings indicate that mHealth tools and wearable trackers yield variable impacts on PA engagement. Conclusion: Future research must adopt higher methodological standards. Comparative studies on PA interventions require caution due to limitations such as insufficient research, inadequate compliance assessment tools, potential biases, and the absence of randomized controlled trials. The inconsistent outcomes from current intervention studies highlight the necessity for developing PA programs guided by intervention mapping or the Behavior Change Wheel, emphasizing high-quality methodologies tailored to specific target demographics.

Published: February 2025

Introduction: Wheelchair sports, such as wheelchair rugby (WR), are intermittent in nature, combining high- and low-intensity actions. Although some data exists on the effects of caffeine intake in WR players, further research using specific physical tests related to the demands of WR gameplay is necessary.
Aims: The aim of this study was to analyze the acute effect of caffeine supplementation on neuromuscular performance and repeated-sprint ability (RSA) in WR players.
Methodology: A total of four WR players participated in this study. Participants ingested 4 mg/kg of anhydrous caffeine dissolved with saccharin in 200 mL of water (CAF) and 200 mL of plain water with saccharin (PLA) 45 minutes before warming up. The following tests were performed: rotator cuff maximum voluntary isometric contraction (MVIC) test, initial maximum push-rim propulsion (IMPRP) test, 10-m sprint test and RSA test (12 x 5 m).
Results: CAF resulted in increased strength and power values in the MVIC and IMPRP tests (≈14.0–18.0%). Also, the CAF group reported a shorter sprint time at 3 (≈5.0%), 5 (≈3.0%), and 10 meters (≈2.0%).
Discussion: Improvements in distance in the IMPRP as well as in a 20m sprint test have previously been reported in WR players after ingesting 4 mg/kg caffeine.
Conclusions: The intake of 4 mg/kg of caffeine 45 minutes before warming up could be slightly enhance performance, especially in neuromuscular actions, in WR players.

Social integration and associational behaviour of male Asian elephants in northwest India: a new social learning
Authors: Puri Kanchan , Joshi Ritesh , Singh Abhishek K
Published: February 2025

It has been widely acknowledged that adolescent male African elephants (Loxodonta africana) associate with other male elephants after leaving their natal family units, which facilitates in learning social behaviour and surviving in adverse environmental conditions. This aspect has been less studied in Asian elephants (Elephas maximus) and studies on male-male interactions are scarce. Social integration of adolescent males with other male Asian elephants, living either solitary or in small all-male elephant groups is a dynamic process that occurs over a period of several years. This study elucidates the behaviour of an adolescent male Asian elephant and its integration into an all-male group. Further, this study also explains a long-term association of male Asian elephants, which has not been reported previously from the region. The study aims to observe the behaviour of male Asian elephants during the adolescence stage, as well as to observe male-male interactions and long-term associations. We conducted the study in Chilla forest range of the Rajaji National Park and adjacent forests, namely, Haridwar and Lansdowne forest divisions, respectively. Observations spanned over a period exceeding more than a decade from 2006 to 2017, focusing on adolescent behaviour between 2007 and 2011 and male-male associations from 2006 to 2017. We propose that this study is a first ever report in context of behavioural learning in male Asian elephants in northwest India.

MUSIC, DANCE AND MESSAGING IN THE GHANAIAN POLITICAL ARENA
Authors: Jebuni T. S. , Bukari G. A.
Published: February 2025

This paper examines how music and dance shape electoral accountability in Ghanaian politics. With political party proliferation and the electoral contestation in Africa in the 1990s, scholars began to explore factors that influence electoral outcomes. Numerous academic studies have found a number of characteristics that impact electoral outcomes in the new democracies, including clientelism, ethnicity, retrospective voting, ideological stances, and rational voting. Beyond these factors, music and dance play an important role in the multiparty electoral systems in Ghana. Despite this purpose, there is comparatively little research on how dance and music contribute to electoral responsibility. Our paper contributes to filling this knowledge gap by analyzing music and dance in the Ghanaian electoral politics by analyzing the impact of ‘Yen tie Obiaa,’campaign song for the 2016 and 2020 general elections by a Ghanaian Highlife icon, Charles Kwadwo Fosu (a.k.a Daddy Lumba). Drawing from twenty (20) participants, the findings revealed that lyrics of the song in addition to other electoral undercurrents have also adversely affected the candidature of the National Democratic Congress (NDC), and influenced voters who hitherto had no intention of voting for the New Patriotic Party candidate in the 2016 and 2020 presidential election.

Published: February 2025

This study examines institutional factors that enhance undergraduate students’ retention in universities in Bayelsa State, Nigeria, with a focus on academic and financial support services and the implications of their effective management. Employing a descriptive survey design, data were collected from 300 undergraduate students and 80 academic staff across two universities: Niger Delta University, Ammassoma, and the University of Africa, Toru-Orua. The research instrument used in gathering data for the study is a 15-item self-constructed questionnaire prepared by the researchers titled “Managing Institutional Factors for Enhancing Undergraduate Students’ Retention Questionnaire (MIFEUSRQ), yielding a Cronbach’s Alpha reliability coefficient of 0.78. Findings revealed that academic support services significantly enhance student retention, as evidenced by the grand mean score of 3.25 for items such as faculty mentoring, advisory committees, and workshops. Financial support services also contributed substantially, with a grand mean of 3.17, highlighting the positive impact of scholarships, financial aid awareness programs, and grants on reducing students’ financial burdens. Furthermore, the aggregate percentage score of 85% of academic staff emphasized that effective management of institutional factors, including academic and financial support services, could serve as a model for resource-constrained universities to enhance retention. They also noted the importance of cross-institutional collaboration and community engagement in fostering supportive learning environments. This study concludes that managing academic and financial support services is pivotal to retaining students in Bayelsa State universities. The findings underscore the need for strategic policies, collaborative efforts, and resource optimization to improve student retention rates, reduce attrition, and ensure institutional sustainability. These insights provide actionable recommendations for university administrators, policymakers, and stakeholders committed to enhancing higher education outcomes in Nigeria.

Published: February 2025

This study explores the factors that affect sustainable tourism practices in rural communities in Hainan Province, China. The theoretical perspective of social exchange theory is typically structured with a well-defined dimension. Previous research has not underlined the importance of investigating new factors influencing sustainable tourism. This study takes a qualitative approach, employing in-depth interview techniques, with 14 Shi Cha Village villagers interviewed in-depth, and the data is analyzed using Nvivo12 software. The model of sustainable development of agricultural community tourism is established based on the qualitative findings. The findings show that Shicha Village, as a rural tourism destination, has abundant natural and profound cultural resources, which are the primary conditions for tourism development. Brand development is an unavoidable option for increasing the community's popularity and ensuring the long-term development of tourism. This study adds three new variables to the Social Exchange Theory: brand, policy, and leadership. The research findings have practical implications for rural tourism decision-makers and managers.

Authors: Supina Supina , Kumar Jeetesh , Rasoolimanesh Seyyed Mostafa
Published: February 2025

By integrating social exchange theory, the norm activation model, and the theory of planned behaviour, this study investigates the effects of awareness of environmental consequences (AEC), environmental attitudes (EA), and local communities’ attachments (LCA) on perceptions of tourism impacts, including economic, environmental, social, and physical impacts. Four hundred seventy-eight responses were collected from local communities in Bogor Regency, Indonesia, and the data was analysed using Smart PLS version 4. This study analyses all factors influencing perceptions of tourism impacts to fill the gap from earlier conceptual and empirical studies. Further, it was found that environmental attitudes needed to influence all perceptions of tourism impacts, and local communities also needed to influence perceptions of social impacts. By analysing a thorough model, this study advances factors of perception of tourism impacts by providing supporting and non-supporting factors. Practical applications and potential research directions are discussed.

Published: February 2025

Propolis, an organic material crafted by bees from a blend of their salivary secretions, beeswax, pollen, and resins, contains essential organic compounds. Phenolic and flavonoids, crucial for their antioxidant properties, are prominently present in this resinous substance. The antioxidant capabilities of propolis extract from Geniotrigona thoracica (G) and Heterotrigona itama (H), two species of Indo-Malayan stingless bees, were examined in this study by using different solvents (ethanol, E and water; W). The analysis involved four extracts of stingless bee propolis which included the ethanolic extract of G. thoracica and H. itama (GE and HE), and water extract of the two species (GW and HW). The Folin-Ciocalteu method evaluated total phenolic content (TPC), while colourimetric techniques were utilised for total flavonoid content (TFC) estimation. Additionally, antioxidant strength was assessed through ferric-reducing antioxidant power (FRAP) as well as IC50 values from the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. The findings confirmed that HE offered the most elevated values for both TPC and TFC, with 52.775 mg GAE g-1 and 467.37 mg QE g-1, respectively. Meanwhile, the IC50 value was comparable among HE and GE at 0.351 and 4.536 mg/ml, respectively, compared to HW and GW (11.985 and 30.93 mg/ml). Consequently, both species are competitive natural sources of antioxidants under the same solvent. While ethanolic extract propolis demonstrates superior antioxidant properties, water extract demonstrates potential benefits, including being consumer-friendly and environmentally sustainable, making it a cost-effective alternative worth exploring. The extract holds promising potential for future applications, including in the cosmeceutical, functional food, and pharmaceutical industries.

Clascoterone (Winlevi)
Authors: CDA-AMC
Published: February 2025

Canada’s Drug Agency (CDA-AMC) recommends that Winlevi not be reimbursed by public drug plans for the topical treatment of acne vulgaris in patients aged 12 years and older.
Evidence from 2 clinical trials demonstrated that Winlevi increased the rate of treatment success (assessed using a measure of overall acne severity) compared with its vehicle cream (without active ingredient).
Patients identified a need for treatments that improve skin clearance (i.e., reduce the number of acne lesions and prevent scarring) and health-related quality of life (HRQoL). However, based on the evidence reviewed in the initial meeting and the reconsideration meeting, the Canadian Drug Expert Committee (CDEC) could not determine if Winlevi would address the unmet needs relative to other active treatments. This uncertainty stems from missing data, a lack of HRQoL data, and uncertainty about whether the results were clinically meaningful. There were limitations in the submitted indirect evidence that also made it uncertain how Winlevi compares to other acne treatments in terms of efficacy and tolerability.
Genome-wide genetic characterization and selection signatures in Anatolian Merino sheep
Authors: Karsli Taki
Published: February 2025

Abstract. Molecular characterization and identification of selection signals at the genome-wide level facilitate the enhancement of ongoing conservation and selection studies in farm animals. This study aimed to reveal genomic diversity and selection signatures in Anatolian Merino sheep via 351 539 bi-allelic single-nucleotide polymorphisms (SNPs) obtained from the double-digest restriction-site-associated DNA sequencing (ddRADseq) technique. Genetic variability parameters such as minor-allele frequency (MAF), nucleotide diversity (π), observed heterozygosity (HO), and expected heterozygosity (HE) were estimated to be 0.340, 0.235, 0.258, and 0.235, respectively, while the inbreeding coefficient was 0.027 based on runs of homozygosity (ROH). A decreasing trend was detected in the effective population size of Anatolian Merino sheep, the current population of which turned out to be descendants of an ancestral population covering 2500 individuals 400 generations ago. Significant selection signals were detected in 464 SNPs within 14 genomic intervals via the ROH approach, whereas 259 SNPs were categorized into 79 genomic intervals by integrated haplotype score (iHS) statistics. A total of 37 and 72 protein-coding genes overlapped with detected genomic intervals in ROH and iHS approaches, respectively. A survey of a sheep QTL database confirmed that selection signals covered 66 QTL-associated SNPs. A large part of the protein-coding genes under selection pressure were mainly associated with milk production (ROBO1, FSIP2, COBLL1, PTPN12, GSAP, CCDC146, FGL2, FAM185A, FBXL13, LOXL2, R3HCC1, CHMP7, RHOBTB2, PEBP4, SRGAP3, and RAD18) and udder morphology (SYT1, GFPT2, MAPK9, and RASGEF1C), while numerous genes turned out to have effects on total muscle area (PCDH7), bone density (SDK2), carcass traits (MBL2), fecal egg count (LGSN), and immunoglobulin A level in blood circulation (RFXAP, SERTM1, BEND7, PRPF18, FRMD4A, and GRAMD1B). The results of this study confirm that high-density next-generation sequencing (NGS) data could be utilized to characterize local sheep breeds to shape conservation programs and shed light on the past breeding practices of the populations whose phenotypic records are absent.
Rockfall triggering and meteorological variables in the Dolomites (Italian Eastern Alps)
Authors: Bonometti Francesca Noemi , Dattola Giuseppe , Frattini Paolo , Crosta Giovanni Battista
Published: February 2025

Abstract. Alpine areas are undergoing the highest change in temperature and rainfall intensity that represent main rockfall triggering factors. Since few approaches were proposed to analyse it, a new approach using meteorological variable frequencies was developed to comprehend climatic scenarios from 1970 to 2019 with implication on triggering historical rockfall events in the Dolomites. The analysis considered key climate variables: mean air temperature, precipitation, thermal amplitude, freeze/thaw cycles and icing, under different aggregation scales. Results reveal that highest warming rates were observed during spring, while a notable reduction in icing and freeze-thaw cycles frequency was obtained during spring and autumn. An anticipation of both starting of summer and ending of winter was detected. Analyses with Rescaled Adjustment Partial Sums method provided valuable insights into precipitation long-term trends and fluctuations. The analysis showed an increasing trend over last decade (2000–2019) suggesting variation in precipitation frequencies over years. The Bayesian method was employed to study conditional probability of meteorological variables on rockfall events. Rockfalls and high intensity rainfall are correlated in autumn, while with mean temperature at different altitudes in summer and autumn. Higher values probability of temperature amplitude characterises spring, while autumn seasons are interested to high temperature variation values. Finally, it was observed strong dependency of the freeze-thaw cycles and icing periods by regional timeseries.

Published: February 2025

Abstract. Isoprene, a volatile organic compound (VOC) emitted by plants, plays a significant role in atmospheric chemistry and climate. The Amazon rainforest is a globally-relevant source of atmospheric isoprene, influencing regional and global atmospheric composition. We report isoprene emissions for 2019 inferred from the Cross-track Infrared Sounder (CrIS) and the local sensitivities between isoprene emissions and isoprene columns determined by the GEOS-Chem chemical transport model. Compared with the MEGAN bottom-up inventory of isoprene emissions, the isoprene emission estimates inferred from CrIS have different spatial and seasonal distributions with generally lower emission rates but with higher emission rates over the north of Amazon basin and southeast of Brazil. Isoprene mole fraction data collected at the Amazon Tall Tower Observatory (ATTO) are invaluable for evaluating isoprene emission estimates. The observed mean isoprene concentration at ATTO, March—December 2019, is 3.0 ± 2.2 ppbv, which is reproduced better by the GEOS-Chem model driven by isoprene emissions inferred from CrIS (2.8 ± 1.4 ppbv) than by the MEGAN inventory (4.1±1.3 ppbv). GEOS-Chem model formaldehyde (HCHO) columns, corresponding to isoprene emissions inferred from CrIS, are generally more consistent with TROPOMI data (normalized mean error, NME = 43 %) than the HCHO columns corresponding to MEGAN isoprene emissions (NME = 50 %), as expected. They also improve the model agreement with regional TROPOMI HCHO:NO2 column ratios that are indicative of changes in photochemical regime. Our results provide confidence that we can use CrIS data to examine future impacts of anthropogenic activities on isoprene emissions from the Amazon.

Abstract. Recent observations of nitrous acid (HONO) in the remote troposphere found much higher concentrations than can be explained through known sources, with important implications for air quality and climate. Laboratory evidence and modelling of field observations suggests that nitrate aerosol photolysis is the likely mechanism providing the additional HONO, offering a rapid route for recycling of NOx from nitric acid (HNO3). Previous studies of the global impact of this chemistry have used either very restricted HONO data or a “top-down” approach to parameterize the HONO source by reconciling simulated and observed NOx concentrations. Here, we use multiple, independent tropospheric HONO observations from different locations to parameterize nitrate photolysis, and evaluate its impacts on global atmospheric chemistry using GEOS-Chem. The simulations improve agreement between modelled and observed HONO concentrations relative to previous studies, decreasing the model bias by 5–20 %. The remaining (and large) underestimate of HONO in the model is due predominantly to an underestimate of total nitrate aerosol (-95 %) and is reduced to 20 % when accounting for low model nitrate. Despite the low bias in the model HONO, we find that nitrate aerosol photolysis leads to substantial global increases in NOx, O3 and OH concentrations, likely beyond the observational constraints. The additional source of NOx (~48 Tg N yr-1 globally) is comparable to total NOx emissions from all sources (~55 Tg yr-1). These HONO observations in the remote troposphere, thus imply a large uncertainty in the NOx budget and an incomplete understanding of atmospheric chemistry.

Abstract. Tungsten (W) concentrations in fluids in equilibrium with crystalline tungsten oxide are used to determine thermodynamic parameters for W solubility and W species in hydrothermal fluids. The solubility data were measured in situ at high pressures and temperatures using X-ray absorption. X-ray spectroscopic data measured in situ – with X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) – were applied to characterize the symmetry and the type of atoms of the first coordination shell of W aqueous complexes present in the fluid at given temperatures and pressures. Experiments were performed at up to 400 °C and at pressures of 40, 50 and 60 MPa. With this dataset, we were able to improve constraints for the already-suggested fluid species WO42-, HWO4-, H2WO40, NaWO4- and NaHWO40. Further, we were able to introduce the H3WO4+ species that is found to be dominant in acidic fluids. No evidence was found for W species involving Cl− as a ligand. The ionic W species found in the fluid are characterized by a tetrahedral complex at alkaline conditions. In neutral to acidic conditions, W complexes with distorted octahedral symmetry are formed. These complexes may be polymerized at temperatures ≤200 °C and W concentrations >10-3 mol kg−1 H2O. X-ray spectroscopy as well as thermodynamic modeling suggests that polytungstate species are not relevant at equilibrium concentrations found in the solubility experiments of this study (≤10-3 mol W kg−1 H2O in equilibrium with tungsten oxide) or at concentrations reported for natural systems. Using the thermodynamic properties of the species mentioned above, in situ data on the solubility of scheelite can be successfully described. Thermodynamic modeling shows that scheelite solubility and wolframite solubility strongly increase with increasing salinity, especially up to 1 m NaCl (m denotes molality), and vary with pH, which is consistent with earlier reports. Overall, this study provides improved thermodynamic properties for a set of W fluid species that cover a wide range of fluid compositions, which is necessary for understanding the complex processes of W enrichment and mineralization in hydrothermal systems.

Abstract. We developed a climate data record (CDR) of atmospheric column water vapor (CWV) and sea surface temperature (SST) under oceanic rain-free conditions using over two decades of observational records from three satellite instruments: the Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E), the MicroWave Radiation Imager (MWRI), and the Advanced Microwave Scanning Radiometer-2 (AMSR2). The AMSR-E and AMSR2 satellites operated in near-stable orbits, while the MWRI experienced orbital drifts of nearly an hour during its operational period. The CWV and SST products were retrieved from well-recalibrated level-1 brightness temperatures observed by common channels with the same frequencies on these instruments, designed for measuring these properties. Adjustments for diurnal drifting errors caused by orbital drift were applied to MWRI data using a semi-physical model developed in previous studies. The combination of prior recalibration and diurnal drift adjustment ensured inter-satellite consistency in the CDRs. Compared to in-situ radiosonde and buoy observations, the biases and root mean square errors of the CDRs are within 0.1 mm and 4.4 mm for CWV, and 0.2 K and 1.6 K for SST, respectively. Long-term trends of the retrieved CWV and SST align with observations from the Global Navigation Satellite System (GNSS) and the Global Tropical Moored Buoy Array (GTMBA) products. The global oceanic trends of CWV and SST were 0.39 mm decade-1 and 0.16 K decade-1, respectively, over the period 2002–2022. Inter-consistency between CWV and SST, as well as layer-mean temperatures derived from satellite microwave sounder observations, was examined and compared with climate model simulations from phase 6 of the Coupled Model Intercomparison Project (CMIP6). It was found that the trend ratio of the retrieved CWV to SST was 9.9 % K-1 in the tropics, which closely aligns with CMIP6 models. These validation results indicate that the presented CDR has high accuracy and is suitable for long-term climate change research. The CDR dataset is publicly available at https://doi.org/10.5281/zenodo.14539414 (Fu et al., 2024).
