Enhancing Students’ Understanding of Variance Estimation through the Lens of the Bias-Variance Trade-off: From Sample Variance to Improved Insight
type: item
description: Understanding variance estimation is a cornerstone of statistical education. While the unbiasedness of the sample variance is a valuable property, it should not be the sole criterion for selecting an estimator. This paper advocates for incorporating mean squared error (MSE) considerations into the teaching of variance estimation in statistics classrooms. In contemporary applications, estimators with lower MSE are often preferred, even when they are biased. In this study, we first examine the relationship between the minimum-MSE variance estimators—among those based on the sum of squared deviations—and the kurtosis of the underlying population distribution. Furthermore, we demonstrate that, particularly for skewed distributions, alternative estimators can substantially outperform the sample variance in terms of MSE. By using variance estimation as a framework, instructors can effectively introduce students to the bias-variance trade-off, a foundational concept in statistical estimation and model selection. To support classroom implementation, we provide a series of R codes for the simulation-based visualizations that foster students’ intuition about the interaction between bias and variance.

Analysing Efficiency Methods in the Health Sector
type: item
description: The key role of performance assessment and management was first recognized by large corporations (Bass, 1972), which achieved notable efficiency and success through structured processes and appropriate systems. This trend is reflected in the growing national and international literature on the subject. The relevance of this topic is underscored by the importance of the healthcare sector and the increasing emphasis on service quality. Like the business sector, the public sector must adopt proven methodological solutions to improve performance. Healthcare plays a vital role in society, making its analysis a significant scientific endeavour. This study explores when a healthcare institution operates efficiently and what methods can be used to measure this efficiency at different stages of development. A relative effectiveness indicator is introduced as a potential guideline for evaluating institutional performance within a defined framework. The relationship between efficiency and performance is examined in the context of long-term sustainability. While healthcare primarily focuses on healing, economic analysis is also essential, as financial factors often influence access and outcomes (Pulay, 2011). A research gap is identified in the area of performance management in publicly funded healthcare institutions. Despite existing studies, a comprehensive synthesis focusing on performance measurement and comparative effectiveness is still lacking.

Purchase Intention in E-Commerce: The Role of Trust, Customer Satisfaction and Extended Valance Framework
type: item
description: This paper will investigate the role of Trust, Perceived Benefit, Perceived Risk and Customer Satisfaction on Purchase Intention with E-commerce. Trust and Customer Satisfaction are two crucial metrics that play an essential role in E-commerce success (Kim et al., 2009). However, existing research has not linked antecedents to Customer Satisfaction that prompt Purchase Intention, when combined with Extended Valance Framework, which is an important topic since perceived Quality, Perceived Value and Loyalty may all have a positive relationship with Customer Satisfaction that may influence a consumer’s Purchase Intention. Using a conceptual Extended Valance Framework model the study will examine the direct and indirect effects. The findings will help the e-tailers to develop strategies to increase consumer trust, eliminate risks and drive online sales. This research will largely, contribute to the understanding of e-commerce consumer behavior and will offer practical recommendations for online businesses’ to thrive in building consumer trust and retention.

Automated Breast Ultrasound for Breast Lesion Detection - Literature Review
type: item
description: Early breast lesion detection is crucial for women. According to WHO, breast cancer caused 670 000 deaths globally in 2022. Mammography is one of the best screening tools for early breast cancer detection. Still, with a dose between 3 and 5 mGy to the glandular tissue for a typical mammographic screening examination involving two views of each breast, alternatives might be used if not necessary. Breast ultrasound is an option, especially in young patients and those with dense breasts. This paper aims to present the little-known automated breast ultrasound (ABUS) as a viable alternative to the conventional handheld ultrasound. A literature review was conducted using the keywords “automated breast ultrasound," "ABUS," "ABVUS," and "sonotomography" in the online databases Google Scholar, PubMed, and Web of Science. The review yielded a total of n=267 studies, of which n=83 were considered pertinent. The review was also based on the clinical experience using an ABUS machine at St. Marina University Hospital—Varna (UMHAT “St. Marina Varna”). ABUS is not widely used in most radiology clinics, even dedicated breast clinics. Automated ultrasound is a machine controlled by an X-ray technician or an ultrasonographer, which records a series of breast ultrasound images. The main advantage of the modality is the elimination of operator dependence (with some caveats, which are expanded upon in the “discussion section”), as well as the reduction of subjectivity. If previous studies are available, precise follow-up of the size and localization of breast lesions is possible. However, а suitable additional screening method, АBUS, demonstrates some disadvantages as a diagnostic tool. Some of the limitations are the absence of information for vascularization and the elasticity of a lesion. Possible artefacts include, but are not limited to, retro-areolar shadowing, breathing artefacts, and air interposition between the probe and the skin. ABUS is applicable for screening and follow-up …

A Social Work Centered Approach to Culturally Appropriate
type: item
description: Navigating the healthcare system could prove arduous for the average person, and even more daunting for immigrants, minority and vulnerable persons. Similarly, the proficient delivery of healthcare services that promotes total well-being to help achieve desired health outcomes can also be a cumbersome process for healthcare providers attributable to the enormous task of ensuring equitable access to healthcare. Prevailing impediments in accessing healthcare include language barriers, lack of transportation, low health literacy, payment access, cost of accessing healthcare, culture, gender disparities and mistrust of healthcare providers. The increasing impact of culture on accessing healthcare cannot be overemphasized. While several scholarly works expound on culturally appropriate healthcare and endeavor to address the barriers to accessing healthcare through a clinical or public health lens, a social work-centered approach has not been adequately used in the existing literature on culturally appropriate healthcare. This article introduces a unique viewpoint and framework by exploring culturally appropriate healthcare through a social work centered lens. It offers insights on how healthcare providers, clinicians, and social workers can position themselves to foster culturally responsive healthcare through grounding holistic assessments to help clients access healthcare that honors client identity, mitigates disparities, and fosters trust.

Continuity: From Intuition to Formalization – A Comprehensive Study
type: item
description: This study examines the difficulties students face in understanding the concept of continuity and its connection to key theorems such as the Fundamental Theorem of Algebra. The initial hypothesis suggests that the challenge lies not in the intuitive notion of continuity, but in its mathematical formalization, which is defined through limits within a topological framework. Although students approach problems continuously and intuitively, many struggle to translate their geometric reasoning into formal algebraic representations. To support this transition, the “Robot Trajectories” activity was designed using a Problem-Based Learning (PBL) approach. In this task, 79 students, organized into 29 teams, analyzed different paths a robot could take to reach a target point. The trajectories, represented as piecewise polynomial functions, required students to identify the optimal route and link it to the corresponding function rule, often considering obstacles along the way. While most teams relied on geometric intuition to approach the problem, only a few succeeded in achieving a solid algebraic formalization. These results highlight the gap between intuitive understanding and mathematical formalization, emphasizing the need for support for this transition in engineering calculus education.

Fostering Junior High School Students’ Conceptual Understanding of Charles’ Law Using Contextualized-Interdisciplinary-Based Module
type: item
description: As climate change continues to intensify, the need for scientifically literate and environmentally conscious learners becomes increasingly urgent. This study developed and implemented a Contextualized-Interdisciplinary-Based Module (CIBM) on Charles’ Law, grounded in a Contextualized-Interdisciplinary Approach (CIA) that integrates chemistry, atmospheric science, environmental issues, and technology. Designed for Grade 10 students in the Philippines, the module aimed to enhance conceptual understanding by linking gas laws to real-world phenomena such as the greenhouse effect and rising global temperatures. Using a mixed-method quasi-experimental design, the study combined expert validation, a pretest-posttest of conceptual understanding, and thematic analysis of student reflections. Results revealed that students initially demonstrated only near-proficiency in conceptualizing the volume–temperature relationship and its environmental applications. Following the intervention, students showed significant improvement, with posttest scores reaching high proficiency levels and a large effect size (r = 0.85) confirmed through the Wilcoxon signed-rank test. Qualitative findings further indicated increased engagement, deeper comprehension, and stronger real-world connections, particularly in understanding climate change. The module was also positively evaluated by experts in terms of content accuracy, instructional design, language, and digital integration. These findings highlight the value of contextualized, interdisciplinary, and technology-supported pedagogy in making abstract scientific concepts more tangible, meaningful, and socially relevant. This study underscores the potential of such approaches to advance not only academic outcomes in science education but also critical awareness and preparedness to address global environmental challenges.

Effectiveness of Engineering Design Process (EDP) in Improving Students’ Cognitive Learning Performance: A Meta-Analysis
type: item
description: The engineering design process (EDP) is an innovative problem-solving approach used to develop effective solutions and products. While numerous studies have explored its implementation and potential effects, its impact on cognitive learning outcomes remains unclear. Thus, this current study aimed to evaluate the effectiveness of EDP. Meta-analytic findings from 17 studies with 29 valid datasets published from 2015 to 2024 revealed an upper-medium effect on cognitive learning performance (g = 0.70, p < .001). Additionally, geographic region, group selection, grade level, EDP model, and EDP skills had moderating effects. Furthermore, subgroup analysis indicated that EDP implementation was more effective under the following conditions: (1) increased exposure to EDP, (2) smaller and (3) randomized class sizes (1-30 and 31-50 students), (4) Asian (5) high school students, and (6) the use of EDP models such as DDCTPE (Define the Problem, Decide Possible Solutions, Create the Design, Test, Present, Evaluate) and AIPCTI (Ask, Imagine, Plan, Create, Test, Improve). Overall, the engineering design process significantly enhanced core engineering knowledge and practice, as well as students' cognition and thinking.

Could Long-Term COVID-X or Autoimmune Disorders be Triggered through the Mechanical Spreading of COVID-X -Virus Invades Bacteria -Self-inclusion-?
type: item
description: We wrote this opinion paper exclusively based on the author's experiences. Its main proposal concerns the possibility that a bacteria may have a couple of units of coronavirus-X inside it. The reasoning is primarily physical, where several coronavirus-X units may fit inside a bacterial body. In such a situation, there is the possibility that units of coronavirus-X can be released into the human body, restarting the virus contamination—long-term coronavirus-X. It is the author's opinion that the virus could also live inside a bacteria.

Temporality and its Effect on the Painting Medium of Expression as an Ontological Tool
type: item
description: This article starts from certain more recent perspectives on contemporary painting seen as both a consequence of media hybridization and a condition of Post-Medium (Krauss). In this techno-scientific era of conquering new territories of knowledge, modern painting has reflected its perpetual overcoming of the limits offered by its medium of expression through the so-called revolution of forms, ultimately leading to surpassing the spatial (two-dimensional) limits of the canvas by borrowing from the spatiality and performative nature of temporal manifestation which unfolds to the viewer step by step. At the same time, in this study, new needs for deeper understanding and clarification arise regarding the possibility of painting (art) for ontological revision manifested over time by probing its temporal implications - the way it relates to the past, present, or future - which have influenced these transformations within its medium of expression for understanding the present and shifts in thinking within the new paradigms through comparative analysis.

Evaluation of the Potential Application of a Portable and Wireless Spectrometer in the Forensic and Medical Field
type: item
description: The application of a wireless portable spectrometer for the quantitative detection of Gamma-hydroxybutyrate (GHB), a commonly abused drug, was explored. Unlike existing portable tests that only detect the presence of GHB, the developed method provides quantitative information. The previously published colorimetric test, involving the formation of the ferric complex of GHB, was modified for spectrometric detection. The absorbance of the purple ferric complex exhibits a linear relationship with the concentration of GHB, showing an average coefficient of determination (r2) value of 0.7676. The reproducibility of the developed method was evaluated through an inter-day study of the calibration curve. Results indicate that the method for spectrometric detection of GHB has good precision (RSD = 5.94%).The performance of the wireless portable spectrometer for detecting GHB using the developed method was compared with that of a benchtop spectrometer. Results show that the r2 value for the wireless portable spectrometer and the benchtop spectrometer is 0.8178 and 0.7532, respectively. This suggests that the performance of the portable spectrometer is comparable to that of the benchtop spectrometer. It is demonstrated that the wireless portable spectrometer can perform quantitative analysis for GHB and has potential for onsite application at crime scenes and first response sites.

Influence of Anesthetic Agents and the Perioperative Period on Cancer Recurrence and Metastasis
type: item
description: Cancer remains a leading cause of death worldwide, with its burden expected to increase, particularly in aging populations. The perioperative period and anesthetic techniques used during cancer surgeries are increasingly recognized as factors that may influence cancer recurrence and metastasis. This study investigates the impact of anesthetic agents and perioperative management on cancer outcomes in Iraqi patients. This study involved 68 Iraqi patients (42 males and 26 females) with various types of cancer, including prostate, colorectal, bladder, lung, cervical, breast, and ovarian cancers. The patients underwent surgery under general anesthesia, with follow-up assessments focusing on cancer recurrence, metastasis, and mortality rates. Serum levels of Cancer Antigen 15-3 (CA15-3) were measured using the VIDAS® immunoassay technique. Data were statistically analyzed using SPSS version 24, with results expressed as mean, standard deviation, and p-values. The study found a higher mortality rate in male patients (54%) compared to females (46%), with survival rates significantly higher in females. Cancer recurrence was observed in 46% of males and 43% of females. Serum levels of CA15-3 were significantly elevated in both male (77.97±2.44 kU/l) and female (96.33±3.66 kU/l) patients, indicating its potential as a diagnostic marker for cancer recurrence and metastasis. The results suggest that anesthetic agents, through their direct and indirect effects on tumor cells and the immune system, may influence cancer progression and patient outcomes. This study highlights the importance of considering anesthetic techniques and perioperative management in cancer surgeries to minimize the risk of recurrence and metastasis. The findings suggest that elevated CA15-3 levels could serve as a valuable biomarker for monitoring cancer recurrence. Further research is needed to explore the mechanisms by which anesthetic agents and perioperative factors contribute to cancer outcomes, potent…

Business manager training and employee support
type: item
description: The world is changing, and with it the way we work and how we relate to our work. Businesses face many challenges to which they must adapt if they hope to remain competitive. In addition to the question of an ecological transition, respect for human rights and working conditions is essential. Today, faced with recruitment difficulties and turnover issues, well-being and the quality of life in the workplace have become priorities for companies that wish to maintain their attractiveness and keep their current employees; in this context, motivation is an essential variable. As such, it is necessary to look into current managerial practices and skills and their underlying factors. In this context, we are interested in the impact of managerial practices on employees. The two principal means of becoming a manager are to be promoted “internally” or recruited externally; these two manager profiles differ in training, professional experience and organizational culture. Stemming from the theoretical field of social psychology, notably the “Five core social motives” model (Fiske, 2003), we reflect upon the issue of managerial practices in the context of a France-based business.

An Examination of Learning Using Fourier Analysis of Mathematical Models of Consciousness
type: item
description: The concept of consciousness remains quite possibly the ultimate mystery for humanity. It is somehow linked to the ability to learn and experience the external environment. The process of learning is of utmost importance to any species and yet remains largely not understood. While many experts from varying fields throughout history have attempted to quantify and measure learning, all failed to capture the process with a mathematical explanation. The purpose of this paper is to present three different models of consciousness and their related Fourier transform and evaluate the ability of each to capture some of the behavior that is understood about the conscious experience. There is some evidence that the experience of consciousness as a function of time can be measured in an expression of phase. With this hypothesis, the technique of Fourier transform becomes a useful tool to examine a mathematical model of consciousness that can be transformed from the phase plane to the linearization of time. This paper summarizes some current research on consciousness and learning and perception of time. This paper then presents three different models of consciousness represented as a pulse function, Dirac Delta function, and exponential decay function and examines each model utilizing Fourier transform. Finally, this paper concludes that the intersection between psychology, neuroscience and cognitive science can be made by utilizing analysis tools in the field of applied mathematics.

An Algorithm for Detecting Sentence Validity
type: item
description: In this paper, we introduce an algorithm for determining the grammatical validity of a sentence. We take a similar approach as in (Preller, 2007) and (Lambek, Type Grammar Revisited, 1999) (Lambek, From word to sentence: a computational algebraic approach to grammar, 2008) by encoding the English words based on word type which we call components. A sentence can be described both algebraically and geometrically. Our algorithm generates the geometric portion called underlinks from the generalized reductions of the algebraic portion. Underlinks uniquely determine the reduction of the components leading to the empty string. This is the mathematical basis for determining if a sentence is valid. We also provide a proof for the algorithm’s time complexity of O(n2) along with a Python implementation. This paper is part of a bigger project based on (Coecke, Mehrnoosh, & Clarky, 2010) where we explore the combination of a sentence’s grammar and meaning. This is done by combining two compact closed categories; pregroups represent the grammar of a sentence, and finite dimensional vector spaces describe the meaning of a sentence. Together one compact closed category is created, representing both aspects of the sentence.

The Use of GIS for Land Use Planning: Recommendations for PPGIS in the United States
type: item
description: GIS (Geographic Information Systems) provide the ability to present multifaceted data in a clear and understandable manner, enabling various stakeholders to be informed and actively participate in discussions about future changes to land use. The use of GIS allows for the analysis of complex spatial and temporal data, aiding in community planning and development, resource conservation, and efficient land utilization. While GIS resources have become more accessible in recent years, land use planners in the US have not fully utilized this tool in regards to engaging the public and gaining their feedback in the planning process. In contrast, European countries like Finland and Poland continuously use PPGIS (Public Participation Geographic Information Systems) and publish their processes frequently. A literature review of PPGIS publications from 2015-2023 provides an overview of the limitations of PPGIS and the barriers for use, including lack of participation and limited funding. A review of the literature, as well as an analysis of the impact of the COVID pandemic, are used to determine best practices for incorporating PPGIS into land use planning processes in the US. Recommendations for improving the use of PPGIS in the US include utilizing training programs, active participation in community meetings, and using multiple methods to engage the public.

Statistical Manipulation: An Analysis of Potential Economic Data Tampering
type: item
description: Information on a country’s economy is important for many parties, including domestic politicians, potential investors, and international financial institutions. However, an individual country’s official statistics are generated and published by the governing body, creating the opportunity for manipulation of these measures. Our research is based on the assumptions that all governments are incentivized to exaggerate economic metrics and that stricter measures on civil liberties, like speech and media, allow for this manipulation to remain. We identified two variables suitable for proxying economic growth, per capita Health Care Expenditure (HCE) and per person electricity consumption to compare to the stated economic data. We utilized a Fixed Effect-OLS regression to find the relationship between these proxy variables and Gross Domestic Product dependent on government type for 151 countries from 2000-2020. Our research revealed that, despite two government-type indicators, the relationship between electricity consumption and GDP was greater with more autocratic governments. This provides evidence to support that autocratic governments may manipulate their economic data. This research expands upon the literature on the role both corruption and government style have on GDP, as well as providing additional evidence that governments may have manipulated economic statistics.

Using a Next-Gen Platform and Deeply Digital Curricula to Support Alpha and iGen Learners and Their Teachers
type: item
description: Current curricula and pedagogy need to change to effectively support the learning needs of the Alphas and iGens. The Alpha Generation, children born after 2012, known as the “digital-first” generation, have grown up on hand-held, digital screens not watching television or reading paper-based books. Similarly, the iGens, also known as Gen Zs, university students born between 1995 and 2012, are the first generation to spend their entire adolescence in the age of the smartphone. "With social media and texting replacing other activities, iGen spends less time with their friends in person” (Twenge, 2017). The COVID disruption further pushed the Alphas and iGens onto screens for social interaction and learning. Returning to paper-and-pencil curricula and pedagogy does not serve the needs of these generations. The President’s Council of Advisors on Science and Technology (PCAST) (2010) issued a prescient report describing the potential for deeply-digital curricula to “provide a richer and more engaging experience through interactive components, videos, simulations, hyperlinks …” (p. 77). Alphas' and iGens' deeply-digital experiences outside of school have them expecting deeply-digital learning experiences inside of school. Toward addressing the learning needs of Alphas in Kindergarten through sixth grade and iGen university students, we have been studying how deeply-digital, highly-interactive curricula plus digitally-motivated, pedagogical practices can increase their engagement and achievement in both in-class and remote learning environments.

The Role of the Communication Discipline at Technical Faculties
type: item
description: Students newly admitted to the university must familiarize with the higher education system, must survive to the transition from pre-university system and adapt to the style of learning/organization/evaluation, basically have to adjust to student life. This change from the pre-university system to the university one has a major influence on the young person on several aspects. Some concern personal life, because it is possible for him to access a university in another city or country and then break up with his friends and his current partner. This factor, among many others, can influence school dropout. Thus, in first years of study, the Communication discipline was introduced in the faculties with a technical profile, precisely to improve and facilitate communication in the new environment in which young people develop and to encourage them to work in a team. The paper presents the analysis of the way in which the aforementioned discipline influences interpersonal communication and obviously friendship relations between new colleagues. Two questionnaires were proposed: one for initial evaluation and one after the semester passed, completed by students at the first and at last seminar. The results showed that this discipline is really important and brings added value to collegial relations.

Advancing Image Database Technologies in Clinical Decision Support Systems: A Systematic Literature Review
type: item
description: Image data has played a crucial role in the Clinical Decision Support System (CDSS). While numerous studies have focused on developing techniques to extract valuable information from image data to aid in disease diagnosis, there is a lack of attention on the storage and retrieval technologies for image database. Extracting information from image data for decision making models requires a substantial volume of image data. However, images often come with large file sizes due to their high resolution and complex details, and compressing such data may lead to the loss of critical diagnostic information. Thus, the challenge lies in preserving the relevant information within images while managing data volume. This literature review aims to explore existing research on image-specific database systems, and their techniques for image data storage and information retrieval to enhance the application of images within CDSS. The review also brings attention to the need for specialized database systems that are tailored to handle the unique characteristics of clinical image data. Consequently, this review serves as a foundation for future research endeavors aimed at advancing image data management and utilization in the realm of medical diagnosis and beyond.

Rheophysical Characteristics of Hydrocarbon Flow in Microcracks
type: item
description: The rheophysical aspects of the non-Newtonian behavior of oil-water emulsion during flow in thin channels are considered experimentally. Using the microchannel model it is established that the nonlinear rheological effect in the flow of oil-water emulsion in micro-slits is mainly caused by the value of the electrokinetic potential of the system, by reducing of which it is possible to significantly weaken the non-Newtonian nature of the fluid. To regulate the electrokinetic potential, antistatic additives were used, the optimal concentration of which was established experimentally. Based on the Bingham model, rheological parameters of oil-water flow were estimated at different micro-slit clearances, in the absence and presence of an antistatic additive. It is established that a reduction in the electrical potential leads to a significant decrease in the yield shear stress during the fluid flow in the microchannel.
