Authors: Omega Petra , Alfiani Risti , Sutinah Cucun
Published: February 2025

This study aims to evaluate the financial literacy skills of sixth-grade elementary school students, specifically in the areas of understanding the concept of money, financial planning, and distinguishing between needs and wants. Using a descriptive quantitative method with an ex post facto approach, this research involved 30 students from a public elementary school in Bandung. Data were collected through a multiple-choice test designed to measure students' financial literacy across six key indicators. The results indicate that the average financial literacy of students falls into the low category, with an average score of 56%. The highest-scoring indicator was the ability to distinguish between needs and wants (93%), while the lowest-scoring indicator was awareness of the importance of financial planning (4%). These findings suggest that financial literacy among students needs to be improved, particularly in the area of financial planning. The study is expected to serve as a foundation for the development of financial literacy programs in elementary schools, aimed at enhancing students' financial awareness and skills from an early age.

El presente trabajo se desarrolló a partir de un Diseño de Experimentos de Mezclas (DOE mix) para obtener una formulación de granilla empastada mediante el uso de los componentes granilla (35 – 55 % en peso), fundente (0% - 20 % en peso) y vehículo (45% - 60 % en peso). A partir de dicho DOE mix se ensayaron 18 formulaciones en laboratorio cuyo análisis en Minitab permitió obtener los coeficientes de regresión, gráficas de residuo y gráficas de contorno para la sedimentación, viscosidad, peso por litro, relieve, aplicabilidad y transparencia de la granilla, así como una optimización de respuesta que dio como resultado una nueva formulación denominada GF1 y unas respuestas pronosticadas para sedimentación, aplicabilidad y relieve. La granilla GF1 fue ensayada en línea y con esta se obtuvieron defectos de llenado, marcado de malla y hervido que fueron solucionados mediante la implementación de una bomba de llenado y un ajuste de la pantalla que permitió un área de aplicación de 23×23 cm2 según el recorrido de la espátula, y de 11,38 cm2 por figura en el que se obtuvieron resultados sin defectos. El pronóstico de respuesta para sedimentación y relieve fueron bastante precisos, contrario al de aplicabilidad, esto debido a que las granillas de laboratorio fueron aplicadas manualmente y las de línea con una decoradora automática. Para el escalamiento a nivel industrial es necesario ajustar adecuadamente la decoradora para controlar el llenado para la puesta a punto en línea, la granilla fue aprobada para el traslado de listellos que cumplan con áreas de aplicación menores a las especificadas previamente.
Podcasting the Truth: Challenging Journalistic Knowledge and Building Epistemic Authority in Independent YouTube Podcasts
Authors: Vaarala Viljami
Published: February 2025

The legitimacy of journalism as a truth-teller has become contested during the era of digitalisation and newly emerging platforms. Recently, the epistemic authority of legacy journalism has been challenged by right-wing podcasting. This article explores metajournalistic discussions on the identity of legacy journalism as a truth-oriented practice and institution in six Finnish podcasts published independently outside legacy media on YouTube. This metajournalistic discourse of truth is identified through topic modelling in 229 podcast episodes, of which 119 are scrutinised using qualitative discourse analysis. The discursive articulations in the YouTube podcast episodes are assessed in the light of realist and antirealist philosophies as well as epistemic theories of journalistic truth structured by critical realist and pragmatist philosophies. The results show that the epistemic authority of legacy journalism is challenged through three interconnected themes through which legacy journalism is articulated as an antirealist practice and institution. By contrast, YouTube podcasting is framed as a platform for a balanced, authentic, and uncut talk that realises the epistemic ideals of journalism. The challenges to the epistemic authority of legacy journalism presented by the Finnish YouTube podcasts are also similar to those identified in previous research on right-wing podcasting and online counter-media. The findings point to the need for legacy journalists and podcasting practitioners to adopt more nuanced and context-bound understandings of journalistic knowledge and truth structured by critical realist and pragmatist philosophies.
Waterfront Redevelopment Five Decades Later: An Updated Typology and Research Agenda
Authors: Tommarchi Enrico
Published: February 2025

Since the second half of the twentieth century, when maritime practices began migrating outside their traditional central city areas, urban regeneration at the water’s edge has been one of the key issues in port cities’ planning agendas. Waterfronts in port cities have become strategic areas for a range of reasons, such as economic growth, city branding, and addressing housing pressures. However, recent studies also show how their transformation is now more profoundly influenced by hypermobile capital and global finance, and by broad sustainability concerns. The established narrative of waterfront redevelopment as a response to weakening port‐city relationships no longer necessarily represents the present of all port cities, as more nuanced accounts are needed. With examples from Europe and across the world, this article reflects on waterfront redevelopment practices, by building on existing attempts to provide typologies and periodise the history of this phenomenon and focussing on the key approaches emerging in the last decades. It is argued that today’s approaches to waterfront redevelopment, and ultimately contemporary relationships between ports and cities, are changing and possibly differentiating from the “port out, city in” rationale underpinning past schemes. Current practices appear to be ranging from the wholesale transformation of redundant waterfronts into neoliberal urban spaces for consumption and capital accumulation to more “fine‐grained” planning strategies to build more (environmentally, but also economically, socially, and culturally) sustainable urban waterfronts by integrating or restoring port‐related activities within mixed‐used areas.

ATYPICAL EPIDIDYMO-ORCHITIS WITH SCROTAL MANIFESTATION OF ENTAMOEBA HISTOLYTICA WITH CONCURRENT MORGANELLA MORGANII INFECTION.
Authors: Sánchez Pérez Mario Paul , Castellanos Donoso Patricia , Flores Bustamante Al , Cárdenas Aguirre Carlos Alberto , Rey Nodar Severino
Published: February 2025

Epididymo-orchitis is a common cause of acute scrotal pain, typically resulting from bacterial infections, with approximately 600,000 cases diagnosed annually in the United States. While most cases are attributed to sexually transmitted pathogens such as Neisseria gonorrhoeae or Chlamydia trachomatis in younger men and gram-negative organisms like Escherichia coli in older patients, rare parasitic infections can complicate the clinical picture. We present the case of an 82-year-old male with a complex medical history, including severe coronary artery disease, hypertension, and a recent Transcatheter Aortic Valve Implantation (TAVI), who developed left-sided scrotal pain and swelling. Initially diagnosed with orchiepididymitis and treated with antibiotics, his condition deteriorated, leading to recurrent febrile episodes and worsening symptoms. Imaging revealed a multiseptated scrotal collection and ischemic testicular changes. Surgical exploration uncovered purulent material, which cultured Morganella morganii, and histopathological analysis surprisingly revealed Entamoeba histolytica morphology with phagocytosed erythrocytes, an exceedingly rare finding in extraintestinal amebiasis. Stool and serological tests for E. histolytica were negative, suggesting isolated scrotal involvement. The patient underwent left orchiectomy, received broad-spectrum antibiotics followed by targeted therapy, and recovered without recurrence over a five-month follow-up. This case emphasizes the importance of considering rare parasitic infections in atypical or refractory presentations of epididymal-orchitis, particularly in regions where E. histolytica is endemic or in patients with unique clinical histories. The unusual scrotal involvement of E. histolytica, with only one other documented case, highlights the diagnostic challenges and emphasizes the role of a multidisciplinary approach combining surgical intervention, microbiological studies, and tailored antimicrobial therapy. This report expands the understanding of extraintestinal amebiasis and reinforces the need for vigilance in identifying rare etiologies in urological conditions.

HIV-1 Tat Activates ERK1/2 Signaling in HBV-infected Hepatocytes to Inhibit HBV Replication and Promote Hepatocyte Survival
Authors:   , Yeakle Kyle Christopher , Nonnemacher Michael R. , Bouchard Michael
Published: February 2025

Globally, a chronic hepatitis B virus (HBV) infection is the leading cause of hepatocellular carcinoma (HCC). The increased risk of HCC persists in patients treated with antiviral therapy, despite suppressing viral replication. Co-infection with human immunodeficiency virus (HIV) increases the risk of developing HCC by 18-fold relative to an HBV mono-infection. Despite the clear clinical burden posed by an HIV/HBV co-infection, the mechanisms underlying the increased risk of HCC are understudied due to a lack of relevant model systems. We developed an in vitro model of HIV/HBV co-infection using Jurkat cells with inducible expression of HIV-1 Tat co-cultured with HBV-infected primary rat hepatocytes. The co-culture model was used to investigate the effect of HIV-1 Tat on HBV replication and cell survival in HBV-infected hepatocytes. Results from Jurkat-secreted Tat were complemented with purified HIV-1 Tat to determine the effect of Tat alone. Exposure to Tat significantly upregulated ERK1/2 and NF-[kappa]B signaling and cell survival in HBV-infected and uninfected hepatocytes. The activation of ERK1/2 and NF-[kappa]B signaling by Tat also inhibited HBV replication, which could be rescued by inhibition of ERK1/2 with temuterkib. Tat-dependent activation of NF-[kappa]B signaling and cell survival was also reversed by treatment with temuterkib. Tat-mediated activation of NF-[kappa]B signaling and cell survival is initiated by the TLR-4 cell surface receptor and recruitment of PKC-delta to the plasma membrane. Overall, the results of these studies indicate that Tat-mediated upregulation of ERK1/2 may promote oncogenesis and contribute to the development of HCC during an HIV/HBV co-infection by promoting cell survival.
Examining the Relationship Between Parent Stress and Emotion Dysregulation in Young Children with and without Autism
Authors:   , Resnikoff Annie Whellan , Daly Brian P.
Published: February 2025

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by social communication impairments and the presence of restrictive, repetitive behaviors, interests (Maenner et al., 2023). Autistic children are at risk for experiencing psychosocial challenges, including a higher likelihood of difficulty regulating emotions (Conner et al., 2021), which can be associated with poor functioning, and can be exacerbated by social deficits and limiting social communication (Prizant et al., 2003). Parenting an autistic child can also lead to increased stress in the parenting role when compared to parents of TD children. Therefore, there are important interactional associations between children with poor emotion dysregulation and parents with heightened perceived stress that need to be better understood. This study sought to make an important contribution to the literature by including new age ranges and different methodological approaches to examine the relationship between emotion dysregulation in young children and perceived parent stress, as well as how emotion dysregulation in autism may differentially relate to parent stress.
Role of Perceived Discrimination for Individuals with Overweight and Obesity Attempting Weight Loss
Authors:   , Chabria Reena , Butryn Meghan
Published: February 2025

Perceived discrimination is defined as individuals' subjective perception of judgment, negative attitude, or unfair treatment based on one or more personal characteristics such as gender, age, or race. A growing body of research suggests that perceived discrimination is a risk factor for obesity and weight gain through pathways related to chronic stress, internalized stigma, and self-control. Despite evidence supporting this link, there is minimal research examining the extent to which perceived discrimination might predict outcomes among adults attempting behavioral weight loss (BWL). The present study investigated whether perceived discrimination at baseline predicted weight loss, self-monitoring adherence (i.e., daily weight and calorie tracking), and physical activity (PA) engagement for individuals with overweight and obesity enrolled in a BWL intervention. This study was a secondary data analysis of data from 154 adults with obesity and overweight enrolled in a BWL intervention. Participants were asked to complete self-report surveys measuring perceived discrimination, motivation for weight loss, and demographic information. They were also asked to complete daily self-monitoring of their weight and physical activity. The study aimed to assess if baseline perceived discrimination predicted 3 and 6-month percent weight loss, physical activity engagement, and adherence to daily self-monitoring. Gender, age, weight, and race were the most commonly reported subtypes of discrimination within this sample. Results indicated that perceived discrimination was not significantly associated with weight loss, physical activity, or self-monitoring. However, among participants reporting high levels of discrimination, those with higher self-reported motivation tracked calories on more days compared to those with low motivation. Given the BWL's increased focus on social support, it is possible that participants' psychosocial protective factors buffered the impact of discrimination-related stress. Additionally, variations in the intervention's frequency and content at 3- and 6-month time points may have contributed to unexpected outcomes. Notably, our exploratory analyses revealed that specific discrimination subtypes (e.g., age, gender, race, and weight) uniquely correlated with different eating and physical activity behaviors. Future research should examine (1) whether baseline coping capacity, self-efficacy, and social support moderate the relationship between perceived discrimination and weight-related outcomes, (2) whether self-control, internalized stigma, and stress mediate this relationship, and (3) the unique effects of specific discrimination subtypes on outcomes.
Conformal Protective Coating of Cathode Materials by Oxidative Chemical Vapor Deposition for Enhancing Lithium-Ion Batteries
Authors:   , Seifollahi Mournani Mehran , Lau Kenneth K. S.
Published: February 2025

Lithium-ion batteries (LIBs) are essential for advancing energy storage in electric vehicles and renewable energy systems due to their high energy density, reliability, and longevity. However, their performance is constrained by the low electronic conductivity and poor cycling stability of high-energy-density cathode materials, such as LiNi_(1/3)Co_(1/3)Mn_(1/3)O₂ (NCM), particularly under a high rate of charge and discharge. To address these challenges, this work investigated poly(3,4- ethylenedioxythiophene) (PEDOT) as an electrically conductive polymer coating for NCM111 cathodes that was applied using the solvent-free oxidative chemical vapor deposition (oCVD) process. The oCVD method enables uniform PEDOT coating around the entire hierarchical structure of NCM111 particles, ensuring effective coverage and improved stability at the cathode-electrolyte interface. Specifically, the oCVD deposition temperature and time were identified as critical processing factors affecting PEDOT coating properties and battery device behavior. By optimizing deposition parameters to 110 °C and 80 min, the oCVD PEDOT coating achieved a conductivity of 3,500 S/cm and a thickness of 80-100 nm, which provided a balance of high electrical conductivity and mechanical robustness. Under these conditions, the PEDOT-coated NCM111 cathodes retained 2 91% of their initial capacity after extended cycling of 300 charge-discharge cycles at a 1C rate, compared to only 12% for uncoated NCM111. The rate capability was also significantly improved, with capacity retention of 47% vs. 19% for bare NCM111 when the current rate increased from 0.1C to 5C. Moreover, the impact of crosslinking on PEDOT coatings was explored. By systematically varying the amount of crosslinking of PEDOT to tune its electrical conductivity, it was found that the coating electrical conductivity rather than simply its mechanical stability is important in achieving enhanced battery performance. This work demonstrates oCVD as a versatile technique for producing conformal, conductive polymer coatings, significantly improving the stability, conductivity, and electrochemical performance of high-energy-density LIB cathodes. These findings highlight the potential of electronically conductive polymers, like PEDOT, and the oCVD technique, which enables conformal protection of cathode active materials, as a viable solution for enhancing next generation LIBs with potential for applications in electric vehicles and large-scale energy storage systems.

Medicinal plants play a significant role in various traditional medicine systems worldwide. Nasturtium officinale W.T. Aiton, commonly known as ‘Halim,’ is a herbaceous perennial often used for its multiple health benefits. It serves as a depurative, diuretic, expectorant, hypoglycemic, hypolipidemic, and odontalgic agent and is utilized in the management of various ailments and disorders. This study aimed to evaluate the antimicrobial efficacy of different solvent extracts of N. officinale against Staphylococcus aureus. The antimicrobial activity was assessed through an in vitro assay using the disk diffusion method. Additionally, the minimum inhibitory concentration (MIC) was determined in comparison with standard reference compounds. Among the extracts tested, the chloroform extract of N. officinale (NOCE) exhibited the most potent inhibitory effect, demonstrating significant antibacterial activity. The high efficacy of the NOCE suggests that it may contain active phytoconstituents capable of targeting bacterial strains. Furthermore, molecular docking studies revealed that the phytoconstituents isorhamnetin, luteolin, and quercetin exhibited strong interactions with bacterial DNA gyrase. The molecular dynamics (MD) simulation of the best-docked compound, isorhamnetin, against bacterial DNA gyrase indicated that all parameters were within acceptable limits, and the compound effectively interacted with the receptor. These findings confirm that N. officinale possesses potential antibacterial activity, which may be attributed to the presence of isorhamnetin.

The loss of soil due to erosion is one of the most critical land degradation issues globally, representing a vital asset for both the economy and the environment. To effectively manage and regulate such a global issue, it is imperative to estimate the loss. With technological advancements, methodologies such as Geographic Information Systems (GIS) and Remote Sensing (RS) are crucial in addressing these difficulties. The primary objective of this study was to employ the Revised Universal Soil Loss Equation (RUSLE) model inside a GIS framework to quantify soil loss in the Ranganadi river basin of Assam, providing a more rapid and accurate estimate. Three distinct physiographic units, i.e., Piedmont Plain, Alluvial Plain, and Flood Plain, were delineated. Collected 60 GPS-based soil samples from distinct physiographic units were collected and analyzed for different soil physico-chemical properties, in addition to taking into account a variety of criteria, such as rainfall erosivity factor (R), soil erodibility factor (K), topography factor (LS), cover and management factor (C), and conservation practices factor (P), the RUSLE approach is based on the evaluation of soil loss per unit area. Five basic RUSLE factors, viz., R factor, K factor, LS factor, C factor, and P factor, were used to determine soil erosion. Further, erosion ratio, dispersion ratio, and erosion index are the basic examples of erodibility indicators that were taken into consideration while used to evaluating the erodibility of the soil. The anticipated soil erosion in the above-said area varied from minimal to severe, with values between 0.01 and 27.38 t ha-1 yr-1. Among the physiographic units, alluvial plain soils had the greatest mean soil erosion value of 8.52 t ha-1 yr-1, whereas floodplain landscapes indicated the lowest average value of 3.39 t ha-1 yr-1. The dispersion ratio varied between 0.08 and 0.33, with soils exhibiting a dispersion ratio exceeding 0.15, signifying their vulnerability to erosion. The erosion ratio varied between 0.04 and 0.61, whereas the erosion index fluctuated from 0.06 to 0.84. As a result, this model is particularly useful in anticipating soil loss in an area, allowing community members, legislatures, and other linked agencies to plan ahead of time for future efforts to mitigate the degradation.
Gauging Risk and Protective Factors Contributing to e-Cigarette Use Among Multiracial Youth

Published: February 2025

Background: Currently, e-cigarettes are the most common form of nicotine consumption among youth in the United States. There is a lack of research focusing on e-cigarette use among multiracial youth, yet the sparse literature points toward the adverse consequences of e-cigarettes on multiracial youth. Multiracial youth tend to have higher addiction and prevalence rates of e-cigarette use compared to other racial/ethnic groups. The current research focuses on analyzing e-cigarette use based on parental factors, school factors, prosocial behavior, ease of access, risk behaviors, perception of harm, and sociodemographic differences among multiracial youth.
Methods: A secondary data analysis of the 2020 Student Drug Use Survey (N = 38 048) was performed. Of these, n = 3340 self-identified as multiracial. Descriptive analysis, univariate logistic regression, and logistic regression were performed.
Results: Results indicate that the odds of using e-cigarettes among multiracial youth increase 2 times when not perceived as harmful, 2 times if one is employed, 18 times if involved in high-risk behaviors, and 2 times if in 9th through 12th grade. Additionally, logistic regression demonstrates that parental factors may not be significant in e-cigarette use among multiracial youth.
Conclusion: It is crucial to investigate the association between e-cigarette use and multiracial youth, as they may be disproportionately affected by chronic conditions and fatal diseases linked to tobacco use. Understanding the specific risk and protective factors influencing e-cigarette use within this demographic can help design targeted interventions, particularly for multiracial youth in the Greater Cincinnati region.

İhracat performansı, işletmelerin dış pazarlardaki büyüme başarılarını ölçen önemli bir göstergedir. Lojistik performansı, ülkelerin ve firmaların tedarik zinciri yönetimindeki etkinliğini ve verimliliğini ifade ederken, küresel inovasyon performansı ise ülkelerin ve firmaların yenilikçi faaliyetlerini ve bu faaliyetlerin uluslararası pazarlardaki başarısını temsil etmektedir. Bu araştırmanın amacı, lojistik performansı ve küresel inovasyon performansı arasındaki ilişkiyi, ihracat performansının aracı rolü çerçevesinde incelemek ve ortaya koymaktır. Araştırmada lojistik performans endeksi, küresel inovasyon endeksi ve ülkelerin ihracat sıralamaları dikkate alınmıştır. Araştırmada hipotezlerin analizleri için regresyon ve korelasyon analizleri gerçekleştirilmiştir. Araştırma sonucunda ihracat performansının lojistik performans ve inovasyon performansıyla doğrudan ilişkili olduğu görülürken, inovasyon performansıyla lojistik performans arasında da ilişki tespit edilmiştir. Lojistik yönetimi ve inovasyon stratejilerinin entegrasyonunun, küresel rekabet ortamında sürdürülebilir rekabet avantajı elde etmede kritik bir rol oynadığı görülmektedir. Ayrıca lojistik performans endeksinin, küresel inovasyon endeksi üzerinde ihracat performansının aracı etkisi olmadığı sonucuna varılmıştır.
