Authors: Durmuş Rabia İrem , Kızıltan Nalan
Published: February 2025

This quantitative research investigated freshmen’s Foreign Language Enjoyment (FLE) and Foreign Language Speaking Anxiety (FLSA) through online speaking skills courses in order to promote the quality of online foreign language speaking skills courses by determining hindering and facilitating factors. The present research sample consists of 722 participants from 33 universities’ English Language Teacher Education Programs. It was reached that a significant negative correlation was found between FLE and FLSA. In terms of gender, no significant correlation was found between participants’ gender and their FLE and FLSA. When the region variable effect on FLE and FLSA was analyzed, a significant correlation was detected between regions where the participants’ universities were placed and FLE and FLSA. The analysis also revealed that there was a significant correlation between the degree of plurilingualism and FLE and FLSA. Furthermore, a significant correlation was found between the perceived level of English proficiency and FLE and FLSA which showed that a higher perceived proficiency level was positively correlated with a higher FLE level and vice versa. Moreover, a significant correlation was revealed between speaking skills classroom environment preferences for speaking skills courses and FLE and FLSA; the ones with online classroom preference instead of face-to-face classroom showed higher FLE. In line with the results, pedagogical implications were offered.
A Correlational Analysis of Pre-service Teachers’ Lifelong Learning Tendency and Teaching Motivation
Authors: Kula Sultan Selen
Published: February 2025

This study aims to explore the relation between lifelong learning tendency and teaching motivation among pre-service teachers. In this study, a correlational survey model was used to investigate the relation between pre-service teachers’ lifelong learning tendency and their teaching motivation. The study also examined whether lifelong learning tendency and teaching motivation differed in terms of perception of being a successful teacher in the future and wishing to be a teacher after graduation. The participants of this research were 452 pre-service teachers studying at the Education Faculty of a state university in Turkey in the spring term of 2020-2021. The research data were collected with personal information form and with “Lifelong Learning Tendency Scale” and “Motivation to Teach Scale”. The results obtained from the research showed that pre-service teachers' thinking that they will be successful teachers in the future affects their lifelong learning tendencies and teaching motivations positively. As pre-service teachers' desire to teach after graduation increased, their motivation to teach increased. There is a positive low level significant relation between pre-service teachers' lifelong learning tendencies and their teaching motivation. Teaching motivation of pre-service teachers has a positive low effect on their lifelong learning tendencies. It is necessary for pre-service teachers to have a high motivation to teach and thus have a high lifelong learning tendency, to keep up with the times, to improve themselves, to update their knowledge, and to change.

Authors: Ernas Sevgi , Aksoy Hasan Hüseyin
Published: February 2025

The purpose of this research is to analyze the education-employment relationship in the context of education economics theories, based on the views of overeducated individuals who work in entry-level jobs and have graduated from associate, undergraduate and graduate degrees and have a higher level of education than their colleagues with the same status. The experiences of over-educated individuals were analyzed via content analysis by applying a semi-structured form, which was implemented by the researcher on 31 entry-level employees working in companies affiliated with the Ankara Chamber of Industry. Findings show that the causes of overeducation are economic deprivation, unemployment, field of education, educational expansion, firm structure, and labor market conditions. The recruitment criteria of employers are professional certificates, references, status difference, technical qualifications, personal characteristics, educational qualifications, and experience of individuals.

Published: February 2025

Introducción. El cáncer de vesícula biliar (CVB) es una patología infrecuente, diagnosticada principalmente de manera incidental, durante o posterior a una colecistectomía. Su alta mortalidad se debe al diagnóstico tardío, ya que los síntomas son inespecíficos. En la región andina de Latinoamérica, la incidencia es alta, con un notable aumento de la mortalidad. El objetivo de este estudio fue analizar la epidemiología del CVB en un hospital del suroccidente colombiano.
Métodos. Estudio transversal retrospectivo. Se analizaron los reportes de patología de los pacientes sometidos a colecistectomía entre 2015 y 2020 para identificar casos de CVB. Se registraron variables como edad, sexo, hallazgos intraoperatorios, tipos de cáncer y subtipos histológicos.
Resultados. De los 766 especímenes, 20 casos fueron diagnosticados con CVB (2,6 %). El adenocarcinoma fue el tipo más frecuente (80 %). La edad promedio fue de 65 años, con una mayor prevalencia en mujeres (85 %). La mayoría de los pacientes presentaron enfermedad en estadios avanzados, con compromiso metastásico en el 15 %.
Conclusión. Los resultados reflejan la alta prevalencia de CVB en la región andina y alta mortalidad. El diagnóstico incidental sigue siendo la norma debido a los síntomas inespecíficos y la falta de sospecha clínica. La inflamación crónica y los cálculos biliares continúan siendo factores de riesgo importantes. Este estudio aporta datos clave sobre la epidemiología del cáncer de vesícula biliar en Colombia, subrayando la necesidad de mejorar la detección temprana y la educación clínica.

The reliability of bilateral cerebral laterality for word generation: who is left in the middle?
Authors: Gerrits Robin
Published: February 2025

Although word production is considered a strongly left hemispheric lateralized function, its cerebral asymmetry varies among individuals. The most popular way of determining hemisphere dominance is to calculate a laterality index (LI) by comparing brain activity between the two hemispheres. Large LIs can readily be classified as left or right dominant, but there is no consensus on how to treat bilateral LIs indicating (near) symmetrical activity. The problem with interpreting very small LIs is perpetuated by a lack of reliability, stemming from the challenge of systematically investigating these uncommon cases (usually ≤ 10% of a sample). To address this gap, we performed two studies that investigated the reliability and across-methods generalizability of bilateral LIs obtained from functional transcranial Doppler sonography (fTCDS), an ultrasound-based approach that measures cerebral blood flow velocity. In Study 1, we compared reproducibility of bilateral LIs (n=35) and clearly lateralized LIs (n=32) during a letter verbal fluency fTCDS task across two sessions. While left-lateralized classifications were highly replicable (97% reproduced), poorer reproducibility was observed for bilateral classifications (51% reproduced). In fact, dichotomous left-right categorization yielded more reliable outcomes than assigning participants with bilateral LIs to a separate category (80% reproduced). Study 2 assessed whether small fTCDS asymmetry extended to other instruments for determining cerebral laterality (visual half field method and fMRI). Participants consistently classified as bilateral by fTCDS (n=18) also exhibited reduced group-level asymmetry in these other methods. Based on these results, we suggest that LIs reflect a combination of idiosyncratic cerebral asymmetry, state-dependent fluctuations, and measurement noise. Our findings also indicate that a subset of the population has a neural system for word production that is inherently weakly lateralized, although true hemispheric equivalence is likely extremely rare. Finally, we offer recommendations for classifying asymmetry in clinical and research contexts.
A Supervised Learning Approach to Estimating IRT Models in Small Samples
Authors: Belov Dmitry I , Lüdtke Oliver , Ulitzsch Esther
Published: February 2025

Existing estimators of parameters of item response theory (IRT) models exploit the likelihood function. In small samples, however, the IRT likelihood oftentimes contains little informative value, potentially resulting in biased and/or unstable parameter estimates and large standard errors. To facilitate small-sample IRT estimation, we introduce a novel approach that does not rely on the likelihood. Our estimation approach derives features from response data and then maps the features to item parameters using a neural network (NN). We describe and evaluate our approach for the three-parameter logistic model; however, it is applicable to any model with an item characteristic curve. Three types of NNs are developed, supporting to obtain both point estimates and confidence intervals for IRT model parameters. The results of a simulation study demonstrate that these NNs perform better than Bayesian estimation using Markov chain Monte Carlo methods in terms of quality of the point estimates and confidence intervals while also being much faster. These properties facilitate (1) to pretest items in a real-time testing environment, (2) to pretest more items, and (3) to pretest items only in a secured environment to eradicate possible compromise of new items in online testing.
Breast Cancer Prediction: A Comparative Study of Support Vector Machine and Logistic Regression
Authors: Paudel Nawaraj
Published: February 2025

One of the most common malignancies among women worldwide is breast cancer and a key factor in raising survival rates is early identification. So, it is important to differentiate between malignant (cancerous) or benign (non-cancerous) tumors. Support Vector Machine (SVM) and Logistic Regression are popular machine learning models that has been widely used for binary classification problems including breast cancer prediction. This study explores the effectiveness of SVM and Logistic Regression in predicting breast cancer and compare their performances. This study uses Python programming to implement SVM and Logistic Regression to classify the Breast Cancer Wisconsin dataset from the UCI machine learning repository. Performance metrices such as recall, F1 score, accuracy, precision, and AUC-ROC have all been used to gauge how well these two algorithms work. Upon comparison, the result showed that SVM model outperformed Logistic Regression model on all the performance metrices.

Published: February 2025

There is an identified need to strengthen the field epidemiology workforce training in the Asia Pacific region. In response, the Asia Pacific Consortium of Veterinary Epidemiology (APCOVE) developed an online training program consisting of 36 modules delivered asynchronously and synchronously across 6 months in 2022. We sought to explore the effectiveness of the program based on participant perception and knowledge acquisition. All participants ( n = 139) were invited to participate in focus groups. Framework analysis was conducted using Biggs’ 3P model as a conceptual framework. In total, 93/139 (67%) trainees completed all competencies (36 modules) and 74/139 (53%) trainees participated in one of 12 focus groups. Participants were from the Philippines ( n = 28), Indonesia ( n = 18), Vietnam ( n = 16), Cambodia ( n = 3), Papua New Guinea ( n = 3), Laos ( n = 3), and Timor-Leste ( n = 3). They valued the interactivity of the modules, including online tools, calculators, and knowledge checks. Module content, including case scenarios, was relevant to the region and applicable to participants’ workplaces. Suggestions for improvement included incorporating local face-to-face sessions to complement the online delivery. The median score for the end-of-competency assessment tasks ranged from 42.5 to 45 (out of 50), and the APCOVE online training program provided an effective and scalable framework to ensure access to up-to-date training resources across the Asia-Pacific region. To improve module access and increase engagement, asynchronous online modules are now available and downloadable in six languages. The provision of face-to-face sessions to complement asynchronous online delivery, and engagement from country partners as mentors, will increase effectiveness and sustainability.

Published: February 2025

Diagnostic sample collection, including venipuncture, is critical to diagnosing and treating cattle. Clinical skills models permit learners to practice a skill and improve their competency before performing the skill on a live animal; however, relatively few bovine models exist. This study aimed to develop and validate a bovine coccygeal venipuncture model and rubric for teaching and assessing veterinary students using a validation framework consisting of content evidence, internal structure evidence, and relationship with other variables evidence. Veterinary students ( n = 38) and experienced veterinarians ( n = 12) performed venipuncture on the model while being video recorded. Recordings were scored blindly using a six-item rubric and a global rating score. Time to perform the task and total number of needle sticks were recorded. Veterinarians reported that the model was suitably realistic for students to learn to perform the task ( content evidence). Rubric scores had acceptable reliability ( a = .783, internal structure evidence). Veterinarians received higher rubric scores and used fewer needle sticks to complete the task ( p = .033 and .047, relationship with other variables evidence—level of training). Students’ survey responses were very positive. The evidence collected in this study supported validation of the model and rubric. The use of validated models and rubrics allows educators to teach and assess skills reliably, and the model allowed students to practice the skill repetitively, reducing the use of live animals. Additional studies would be necessary to evaluate the model for use in teaching veterinary technicians, extension agents, and livestock producers to perform this task.

Biblical View of the Causes and Essence of Disease
Authors: Bryndin Evgeny
Published: February 2025

The Holy Scriptures contain specialized references to diseases. References to diseases are very numerous and are found in books of a wide variety of contents. We can find mention of diseases in historical narratives, in edifying reflections, in teachings, and in psalms, as well as in discussions of issues related to ritual purity and temple cult. The Old Testament mentions dozens of different diseases: infertility, pestilence, consumption, fever, fever, inflammation, leprosy, scabs, scabies, insanity, blindness, heart attack, etc. In the New Testament, the topic of illness and healing occupies a very prominent place. Most of the stories about the miracles of the Savior convey cases of miraculous healing: the healing of Peter’s mother-in-law, the centurion’s servant, a bent woman, a bleeding woman, a man born blind, ten lepers and many others (of the 36 miracles mentioned in the Gospels, 26, i.e. more than two-thirds - these are cases associated with healing). Having fallen through the sin of disobedience from the divine power that sanctifies and replenishes nature, man dooms himself to illness and suffering: “in illness you will give birth to children” (Genesis 3:16), God addresses Eve. Diseases are associated with sin, suffering and death.
Digitization Is Not Decolonization
Authors: Gibson Laura
Published: February 2025

A year ago, the South African Cabinet approved the National Policy of the Digitization of Arts, Culture, and Heritage. With a focus on digitizing the country's heritage resources for preservation, access, and management of ownership, this act is emblematic of a broader trend conflating digitization of Africa's cultural heritage collections with decolonization. Yet, by examining how one of the continent's oldest museums documented its ethnographic collections, this article demonstrates how normalized colonial knowledge systems still are, and why decolonization requires more than making collections digitally available. Cognizant of this challenge is Amagugu Ethu, a South African not-for-profit organization, whose work developing a digital Museum-in-a-Box I analyze in the second part of my article as an important way of resisting and interrupting colonial knowledge production in (South) Africa's museums.
Setting Agendas for Mass Media
Authors: Mu Zhitong
Published: February 2025

Communication is obviously an important function for museums. Engagement with mass media is one of the indispensable ways for museums to communicate with their publics. The concept of mass media arose in the early twentieth century and refers to information dissemination accessible to all in principle, including newspapers, magazines, radio, television, and the Internet, and others (McQuail and Deuze 2020: 16–19). In this article, mass media mainly includes the traditional mainstream media, while social media on the Internet will not be discussed. For many people, mass media is still an essential channel for up-to-date information nowadays. In recent years, the national and global mass media has paid increasing attention to museums in China, and their reports on traditional festivals, special events, museum development and International Museum Day have achieved great prominence. However, inaccuracies and negligence in mainstream media reports about museums still occur from time to time, as seen in the case of CCTV News where an author of tomb-raiding novels was invited to a live show to discuss the archaeological excavation of the Sanxingdui Site, Sichuan (The Paper 2021). While this incident invites criticism of the professional standards of journalists, it also raises skepticism about the absence of archaeologists and museum professionals in mass communication. Are museums absent from the communication process? Are museums acting as gatekeepers when reporting on relevant content? What is the relationship between museums and mass media? In this article, I argue that “agenda-setting theory” helps to address these issues.

Modelado discreto de sistemas dinámicos univariados no lineales con aproximación de primer orden
Authors: Bellon Hernández Oscar , Torres Amaya Alvaro
Published: February 2025

This article shows a method to obtain a black box dynamic model of a nonlinear univariated system. A formal theoretical deduction is proposed to justify the procedure and steps to be followed are reported in order to implement them to any univariated system. Two examples are used to validate the explained methodology: a simulated nonlinear univariated system and a direct current motor separately excited. In both cases, the model obtained by difference equations is a segmented linearization of the algebraic function between both input and output variables. Parameters in that equation are dependent of input variable. The explained methodology can be included as an experimental practice in engineering subjects about control theory, modeling and simulation of dynamic systems.

Authors: Parrado Corredor Felipe , Ospina Toro Daniela
Published: February 2025

The gestures and movement recognition technology might support and improve measurements of psychological constructs as self-control, that it is considered a personality trait or an ability of preferring delayed consequences. Traditionally, their assessment is executed with surveys and performance on specific tasks. In this study selfcontrol was measured with a 16-PF test and the choice pattern was assessed with different values of responses from the Iowa Gambling Task. A sample of 85 students of Psychology played in a human computer interface using the Kinect sensor. It was found that the participants had similar earnings and differential time reaction (F (2, 8049) = 3.058, p < .005) and taking play or pass decisions (p < .001) particularly between low and medium self-control rank. The findings point that the use of sensor Kinect is useful to improve technology for classifying choice performance corresponding to psychological concepts.
Ingeniería de Requisitos: de la especificación de requisitos de software al aseguramiento de la calidad. Cómo lo hacen las Mipymes desarrolladoras de software de la ciudad de Pereira

Published: February 2025

The development of requirements is a fundamental step in any software development project because, along with requirements management, ensures that the product developed effectively meets the needs that the customer really has. To achieve this, the Requirements Engineering raises the disciplined execution of a series of activities, among which is highly significant for its role in achieving quality, specification or definition of the requirements. However, this is a complex and rigorous process, and requires very specific knowledge that few universities in the country offer, so that, it is difficult to find qualified professionals for this specific domain in the region. So, ¿how can the local software industry (MSME) offer an appropriate specification requirements?, this article aims to make an approach to the way companies located in the city of Pereira face the topic about requirements; the analysis makes part of an ongoing research project that aims to “develop a procedure to specify and validate software requirements based on previous studies in the region”, as a contribution to a sector that seeks to increase its levels of maturity and quality.

Soluciones para los fluidos entre paredes paralelas y porosas
Authors: Devia Narváez Diana Marcela , Mesa Fernando , Restrepo-Parra Elisabeth
Published: February 2025

A conducting fluid is continuously injected or ejected through a pair of parallel porous walls and it escapes in both directions along the channel. The flow forms a stagnation point at the center and the effluence is restricted by a magnetic field. A theoretical analysis of steady state solutions of the MHD equations in the incompressible case is given as a function of three parameters: the Reynolds number Re, the magnetic Reynolds number Rm and Alfvenic Mach number MA for some of significant asymptotic limits. For highly conducting plasma (Rm >> 1) it was found that the magnetic field restrains the outflow for MA <1 and drives the escape for MA >1. In motions of low conductivity (Rm <<1) the magnetic field contains (and can be used for controlling) the effluence.

Establecimiento de Intervalos de Tolerancia para el Control de Coliformes Totales en el Área de Desposte Bovino
Authors: Corpas Iguarán Eduardo Javid
Published: February 2025

To guarantee product safety, food companies must develop strategies of control of cross contamination, which promote the durability of the food and sustaining of public health. Tolerance intervals were implemented through the analysis of environments, surfaces and food handlers, for total coliform count in the deboning area, which were considered of direct implication to the microbiological quality of the product, until completing ten repetitions for each one. The information obtained was submitted to statistical processing in order to eliminate atypical data, and deleted data were replaced by others, originating of subsequent samplings, that were within of the normality. Finally, from data obtained, tolerance intervals were established for the adoption of specific actions in each type of analysis, when microbiological limits are exceeded, as a complementary transversal action to avoid cross contamination and contribute to product safety.

Objective: To determine the effect of sodium chloride (NaCl) and cultivar on germination and initial growth of huauzontle (Chenopodium berlandieri subsp. nuttalliae).
Design/methodology/approach: A 3 × 5 factorial experiment in a completely randomized design was conducted. Three huauzontle cultivars (Mexico City, Puebla, and Tlaxcala) and five doses of NaCl (0, 75, 150, 225, and 300 mM) were evaluated. Each treatment had five replicates. The germination percentage was evaluated 24 h after sowing, plant height of the seedlings for 11 d, and the weights of fresh and dry biomass were determined at 11 d after germination. The data were analyzed using ANOVA, Tukey’s test (p ≤ 0.05), and a regression model was generated for the variable seedling height as a function of the time of exposure to NaCl.
Results: Seed germination began 24 h after sowing in the three cultivars at all NaCl concentrations evaluated. The germination percentage was reduced by 17.6% at 300 mM compared to the control without salinity. Seedling height was higher in the Mexico City and Tlaxcala cultivars at 75 and 150 mM compared to the control; in these treatments, growth was only inhibited with 300 mM NaCl. On the contrary, the Puebla cultivar showed a reduction in growth starting at 225 mM NaCl. The weights of fresh and dry biomass were only affected by the cultivar study factor, where Mexico City followed by Puebla had the highest means; both higher than Tlaxcala.
Limitations of the study/implications: This study only considers the germination and initial growth phases in the three huauzontle cultivars. Therefore, it is necessary to evaluate the effects of salinity in later phenological stages.
Findings/conclusions: The responses observed in huauzontle in germination and initial growth depend on the NaCl concentration and the cultivar. The germination percentage decreased only with the 300 mM NaCl dose with respect to the control. NaCl at doses of 75 and 150 mM NaCl promoted growth in the Mexico City and Tlaxcala cultivars. The Mexico City cultivar had the highest fresh and dry biomass weights, followed by Puebla and Tlaxcala.

Traditional education is one of the treasures of traditional Islamic education in the archipelago. Langgar was one of the centers of traditional Islamic education in Indonesia before the development of pesantren. This study seeks to present traditional education in the context of Madurese society in Jember. This research was conducted in Langgar Nurul Huda in Kemuning Lor village, Panti District. The research method used is ethnographic, with in-depth interviews with kiai langgar, santri and santri parents. The results showed that the Madurese ethnic community in Jember showed a hybrid society through various cultural expressions in language, symbols, and art. The learning model used in Langgar Nurul Huda seems to provide "cultural communication" that this Langgar is a Langgar that has a Madurean identity; this can be seen from Langgar's various activities. Langgar's traditional education model in Langgar Nurul Huda shows Madurese's identity through language expressions and cultural symbols. The categorization of ethnicity in this study is understood as the habitus of Madurese people formed through the representation of Langgar, the expression of identity "kemaduraan" (Madurese Identity) reflected in the identification of models and learning patterns. The learning style is Pal-apalan, (memorize) Ca'beca'an. (reading), and Ngajhi (recite). It shows how Madurese people in Jember identify their ethnic identity through the distinctive Langgar traditional learning model.
