Use of Machine Learning to Predict Individual Postprandial Glycemic Responses to Food Among Individuals With Type 2 Diabetes in India: Protocol for a Prospective Cohort Study (Preprint)
Authors: Choudhry Niteesh K , Priyadarshini Shweta , Swamy Jaganath , Mehta Mridul
Published: January 2025

BACKGROUND

Type 2 diabetes (T2D) is a leading cause of premature morbidity and mortality globally and affects more than 100 million people in the world’s most populous country, India. Nutrition is a critical and evidence-based component of effective blood glucose control and most dietary advice emphasizes carbohydrate and calorie reduction. Emerging global evidence demonstrates marked interindividual differences in postprandial glucose response (PPGR) although no such data exists in India and previous studies have primarily evaluated PPGR variation in individuals without diabetes.

OBJECTIVE

This prospective cohort study seeks to characterize the PPGR variability among individuals with diabetes living in India and to identify factors associated with these differences.

METHODS

Adults with T2D and a hemoglobin A1c of ≥7 are being enrolled from 14 sites around India. Participants wear a continuous glucose monitor, eat a series of standardized meals, and record all free-living foods, activities, and medication use for a 14-day period. The study’s primary outcome is PPGR, calculated as the incremental area under the curve 2 hours after each logged meal.

RESULTS

Data collection commenced in May 2022, and the results will be ready for publication by September 2025. Results from our study will generate data to facilitate the creation of machine learning models to predict individual PPGR responses and to facilitate the prescription of personalized diets for individuals with T2D.

CONCLUSIONS

This study will provide the first large scale examination variability in blood glucose responses to food in India and will be among the first to estimate PPGR variability for individuals with T2D in any jurisdiction.

Authors: Charlton Jaidyn , Malik Ishaq , Ashley Angela M , Newton Amanda , Toombs Elaine , Schmidt Fred , Olthuis Janine V , Stasiuk Kristine , Bobinski Tina , Mushquash Aislin
Published: January 2025

BACKGROUND

The minimal clinically important difference (MCID) is an important threshold to consider when evaluating the meaningfulness of improvement following an intervention. The JoyPop app is an evidence-based smartphone app designed to improve resilience and emotion regulation. Information is needed regarding the JoyPop app’s MCID among culturally diverse youth.

OBJECTIVE

This study aims to calculate the MCID for youth using the JoyPop app and to explore how the MCID may differ for a subset of Indigenous youth.

METHODS

Youth (N=36; aged 12-18 years) were recruited to use the JoyPop app for up to 4 weeks as part of a larger pilot evaluation. Results were based on measures completed after 2 weeks of app use. The MCID was calculated using emotion regulation change scores (Difficulties in Emotion Regulation–Short Form [DERS-SF]) and subjective ratings on the Global Rating of Change Scale (GRCS). This MCID calculation was completed for youth overall and separately for Indigenous youth only.

RESULTS

A significant correlation between GRCS scores and change scores on the DERS-SF supported face validity (r=–0.37; P=.04). The MCID in emotion regulation following the use of the JoyPop app for youth overall was 2.80 on the DERS-SF. The MCID for Indigenous youth was 4.29 on the DERS-SF. In addition, most youth reported improved emotion regulation after using the JoyPop app.

CONCLUSIONS

These MCID findings provide a meaningful threshold for improvement in emotion regulation for the JoyPop app. They provide potential effect sizes and can aid in sample size estimations for future research with the JoyPop app or e-mental health technologies in general. The difference between overall youth and Indigenous youth MCID values also highlights the importance of patient-oriented ratings of symptom improvement as well as cultural considerations when conducting intervention research and monitoring new interventions in clinical practice.

Published: January 2025

BACKGROUND

The World Health Organization (WHO) developed the Integrated Care for Older People (ICOPE) screening tool to identify older adults with priority conditions linked to declines in intrinsic capacity (IC). However, there is a need for cross-cultural validation of the ICOPE screening tool.

OBJECTIVE

This study aimed to assess the reliability and validity of the ICOPE screening tool, which evaluates six domains—cognition, locomotion, vitality, vision, hearing, and psychological health—in the context of Taiwan.

METHODS

The study population comprised three groups: 185,287 older adults who participated in the national ICOPE assessments in 2023, 716 older adults involved in a regional ICOPE implementation in southern Taiwan, and 53 community-dwelling older adults who underwent a one-week test-retest reliability assessment during June–July 2024, also in southern Taiwan. The study evaluated the tool's convergent validity, construct validity, predictive validity, internal consistency reliability, and test-retest reliability.

RESULTS

Factor analysis identified two dimensions: physical function and life adaptation. Convergent validity indicated significant associations between abnormal IC in overall, physical, and life adaptation domains and the following factors: female gender, older age, lower education (elementary school or below), widowhood, higher number of chronic diseases, screenings conducted at medical centers, screenings conducted at outpatient clinics or inpatient facilities, quality of life, and frailty. Discriminant validity showed that IC abnormalities in the overall, physical, and life adaptation domains were similar among older adults born in different seasons. Predictive validity demonstrated that the overall IC abnormality predicted frailty and dependency in the basic activity of daily living (BADL), with areas under the curve (AUC) of 0.914 and 0.944, respectively, while the physical function dimension predicted these outcomes with AUCs of 0.902 and 0.924, respectively. Internal consistency reliability, assessed by the Kuder-Richardson 20 coefficient, ranged from 0.376 to 0.501. The one-week test-retest reliability showed Kappa agreements for cognition (0.168), mobility (0.372), nutrition (0.542), vision (0.295), hearing (0.237), and depression (-0.031). The intra-class correlation coefficient for the one-week test-retest reliability was 0.503.

CONCLUSIONS

The ICOPE screening in Taiwan demonstrates good convergent, construct, and predictive validity but limited reliability. It can serve as a preliminary screening tool for assessing the IC of older adults with the application of repeated measures and alternate forms.
AI-Driven Resilience Strategies for Enhancing Healthcare Supply Chain Resilience: A Systematic Literature Review (Preprint)
Authors: Ahmed Pir Noman , Shah Adnan Muhammad , Lee KangYoon
Published: January 2025

BACKGROUND

The COVID-19 pandemic has exposed the vulnerabilities of global supply chains (SC), particularly within the healthcare sector, underscoring the need for advanced methods to enhance SC resilience and sustainability. Pandemics, such as COVID-19 and Influenza, pose considerable risks to healthcare supply chain (HSC) performance, demanding robust analytical tools to optimize system efficiency under uncertain conditions.

OBJECTIVE

In this paper, we map the current literature and synthesize insights on the role of leadership in driving Artificial Intelligence (AI)-driven resilience approaches for enhancing HSC within healthcare organizations. This systematic literature review aims to review the HSC-resilience (HSCR) and apply a novel network range directional measure model to evaluate the sustainability and resilience of HSC in response to the COVID-19 pandemic.

METHODS

The systematic literature review followed the PRISMA guidelines, encompassing multiple databases, including Business Source Premier, CINAHL, ACM Digital Library, MEDLINE, PsycINFO, Web of Science, PubMed, and ScienceDirect. The review targeted articles published from 2016 to 2024, focusing on empirical studies. A predetermined search strategy used keywords such as SC resilience, artificial intelligence, healthcare, and related terms. The analysis involved an inductive, thematic approach to qualitatively map the evidence. The screening and data extraction processes were independently carried out by two reviewers, with Cohen's kappa used to assess interrater agreement. Data synthesis was accomplished through a narrative approach.

RESULTS

A comprehensive case study demonstrates the practical application of this model, revealing its capability to assess SC resilience and sustainability under diverse data conditions. The findings highlight how decision-making unit efficiency varies with changing circumstances, showcasing the model’s robustness in evaluating HSC performance during disruptions. The final number of studies included in the systematic literature review was 39. These clinical decision-making units included quantitative and qualitative decision support models 16/39 (41%) and 25/39 (59%), respectively. The earliest article was published in 2018; the most recent was from 2022.

CONCLUSIONS

This study is one of the first to compare AI and conventional human systematic review methods as real-time tools for gathering literature on AI-driven resilience strategies to strengthen HSC. While the model proves effective in assessing SC resilience and sustainability, a key limitation lies in the practical implementation of such advanced methodologies within HSC. Future research should focus on the real-world deployment of these models to strengthen SC resilience in the face of potential disruptions.

Evaluating Prompted Text-Based Vital Sign Recording Versus Unprompted Electronic Medical Record Entries in Patients With Advanced Heart Failure (Preprint)
Authors: Wu Jenny Sue , Chen Julia , Min Lillian , Paul Brandy , Keedy Jenna M. , Ellimoottil Chandy
Published: January 2025

BACKGROUND

Long-term remote patient monitoring, particularly of weight, pulse, and blood pressure, has been shown to significantly reduce mortality and hospitalization rates due to cardiovascular issues in heart failure patients. Despite its proven effectiveness, maintaining patient engagement in remote monitoring programs remains a challenge.

OBJECTIVE

This study aims to evaluate the impact of two-way mobile text-based communication in prompting patients to record key vital signs, and how it compares to traditional, unprompted patient reporting through electronic medical records in terms of engagement and clinical outcomes.

METHODS

We analyzed data from patients participating in the University of Michigan Advanced Heart Failure Program. Participants were required to submit daily reports of their weight, blood pressure, and pulse via one of two methods: the MiChart Patient Outreach Texting Application (MPOTA) or the Patient Enrolled Flowsheets (PEF). The study's primary metric was the consistency of patient-reported vital signs, with secondary metrics including variations in hospitalization and emergency room visits pre- and post-enrollment in the programs.

RESULTS

The study included 890 patients, with 301 in the MPOTA group and 589 in the PEF group, after applying exclusion criteria. The engagement rate for the PEF group had a median of 2.29%, with a range from 0 to 99.76%. In contrast, the MPOTA group showed a significantly higher median engagement rate of 66.67%, with rates spanning from 0% to 100%. Analysis of hospitalization and emergency room visit trends revealed no significant changes following the initiation of MPOTA.

CONCLUSIONS

The findings from this study suggest that while the adoption of the MPOTA system did not result in a noticeable reduction in hospitalizations or emergency room visits, it significantly improved patient engagement levels. This underscores the potential of mobile text-based communication in enhancing patient involvement in remote monitoring programs, particularly for those with advanced heart failure.

Inseguridad certificada de tierras indígenas en México: una aproximación desde los regímenes racializados de propiedad
Authors: Torres Mazuera Gabriela
Published: January 2025

La década de 1990 trazó el giro neoliberal que impactó las políticas agrarias en México y Latinoamérica. Se trata del recambio de la demanda campesina y la redistribución de la tierra hacia la exigencia burocrática y empresarial de la seguridad jurídica en la tenencia de la misma. Después, distintos países emprendieron programas de certificación y titulación agraria que auguraban un nuevo modelo de desarrollo económico. Al mismo tiempo, y de manera contradictoria, múltiples cartas magnas latinoamericanas reconocían, bajo la égida multicultural, los derechos colectivos de los pueblos indígenas, así como nuevas figuras jurídicas, adjetivadas como indígenas, de protección territorial.
¿Hasta qué punto la certificación agraria neoliberal ha garantizado la seguridad jurídica de personas y pueblos campesinos e indígenas en México?, y ¿qué tan efectivo fue el reconocimiento legal de los derechos de pueblos indígenas bajo el giro multicultural para la defensa del territorio colectivo? En este texto nos proponemos responder a estas preguntas, retomando las discusiones cruzadas de los regímenes de propiedad y alteridad nacional mediante las cuales se contrastan los usos y efectos hegemónicos y contrahegemónicos de las categorías de identidad indígena, de ejido y comunidad.
Empirical Discourse on Accounting Conservatism and Financial Performance of Multinational Companies in Nigeria
Authors: Akan David Chucks , Temile Suny Oteteya
Published: January 2025

This study aims at finding out how accounting conservatism influences the financial performance of multinational companies (MNCs) in Nigeria. In particular, it investigates the impact of unconditional and conditional conservatism on the return on equity (ROE) of MNCs in Nigeria. It also considers how financial leverage and size of the firm moderate this relationship. The study takes a positive research approach and collects data from eight cross-sectional entities represented by 120 observations over 15 years (2006 – 2022). During the investigation, information was sought from the sample of eight MNCs that were used. The panel-corrected standard error regression (PCSE) was employed to deal with potential parameterization problems. In conjunction with the regression analysis, several diagnostic tests were conducted including multicollinearity testing, correlation analysis, and descriptive statistics. The statistical software Gretl was used to evaluate the regression results. The results indicate that conditional conservatism enhances the financial performance in terms of the ROE of the sampled MNCs which is significantly higher. On the other hand, unrestricted conservatism has an adverse effect on ROE reducing it. While higher levels of conditional conservatism positively affect the financial performance of MNCs, larger degrees of unconditional conservatism lower their return on equity (ROE). Given these findings, suggestions are given to the management that multinational company managers should opt for conditional conservatism so as to lower information asymmetry in financial reporting since it enhances financial performance as well as operational effectiveness.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Dosik , Jang Hyungshim
Published: January 2025

Objectives This study aimed to examine the mediating effect of organizational characteristics on the relationship between organizational culture and job satisfaction as perceived by middle-aged employees.
Methods Data from the 2nd Wave, third-year Human Capital Corporate Panel (HCCP) of the Korea Research Institute for Vocational Education & Training (KRIVET) were used, targeting 4,239 middle-aged employees aged 40 to 64. Statistical analyses, including reliability and correlation analyses, were performed using SPSS 25.0. To verify the mediating effect of organizational characteristics, Baron and Kenny's three-step regression analysis and the Sobel test were conducted.
Results The analysis results are as follows: First, organizational culture, excluding hierarchy (β = .003), had a significant positive effect on organizational characteristics, with innovation (β = .184, p < .001), relationship (β = .308, p < .001), and market (β = .212, p < .001) showing significant positive effects. Second, organizational culture (innovation: β = .218, p < .001, relationship: β = .281, p < .001, hierarchy: β = .041, p < .05, market: β = .133, p < .001) significantly affected job satisfaction. Third, the mediating effect of organizational characteristics between organizational culture and job satisfaction was confirmed through three-step hierarchical regression analysis. In this analysis, organizational culture (innovation: β = .175, p < .001, relationship: β = .210, p < .001, market: β = .105, p < .001) and organizational characteristics (β = .230, p < .001), excluding hierarchy, were found to have a partial mediating effect on job satisfaction. The significance of this effect was verified by the Sobel test (Z = innovation 7.779, p < .05, relationship 10.525, p < .05, market 5.544, p < .001).
Conclusions The study confirmed that organizational culture, as perceived by middle-aged employees, significantly affects job satisfaction through the mediation of organizational characteristics. These findings provide a practical implication and foundation for developing educational programs that enhance positive organizational characteristics, allowing middle-aged employees in critical roles within organizations and society to experience job satisfaction in environments that emphasize relationship-building, collaboration, change, and innovation, rather than focusing solely on productivity improvement.

A Case Study of Learning Experience in a Real Contexts: Ethno-method Interpretations of Learning Transfer
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Young-Ju , Shon Min-Ho
Published: January 2025

Objectives This study aims to understand learning experiences in real contexts as a core learning science inquiry topic regarding embodiment and transfer in learning.
Methods This study relied on ethnomethodology (EM) as a learning science research method on learning experiences in real contexts. EM opened up the possibility of systematic observation and analysis of embodied experiences and situated learning through qualitative analysis of the composition of real-time situational contexts created by the interaction between agents and practical reasoning and behavior, thereby providing an important research methodology for learning science. EM played an important role in exploring how learners’ internal understanding of concepts they encounter is expressed and changed in the process of embodiment, that is, interaction. The subject of analysis in this study was a 16-hour media literacy class conducted at the graduate school of H University.
Results First, transfer in learning has a dynamic characteristic that continuously appears throughout the learning process. Second, transfer appears in the process of interacting with various factors and recognizing situations to utilize knowledge. Third, transfer is not simply applying knowledge, but is achieved through the process of reconstructing and deeply understanding knowledge in various situations.
Conclusions Transfer in learning is created in the process of integrating knowledge through continuous interaction between participants. In other words, transfer is created in the process of the flow of situational context, which is the interaction with various factors experienced to utilize knowledge. The teaching strategy that promotes transfer can be viewed as a role that maximizes the room for learners to choose their own judgment and actions by opening a space for participation where they can use all the resources that they can take in their own context, including the knowledge. In future research on the design of learning experiences, it is necessary to pay attention to the dynamic conditions and settings of the flow of micro-contexts created by the situational inference and actions revealed by the interaction between agents, which are important key points of learning design.

Published: January 2025

Objectives The purpose of this study was to identify potential groups in perceived media device addiction by mother and child and to explore variables that affect on these potential groups based on previous studies. The study also investigated that whether differences in self-regulated learning ability exists in these potential groups.
Methods 1266 mothers with children in middle school data from the 2021 of the Korean Children and Youth Panel Survey (KCYPS) were analyzed using Latent Profile Analysis to identify the potential group of media device addiction. The effect of predictive and outcome variables was checked using R3STEP, an automated three-stage estimation method, and BCH auxiliary variables.
Results First, the latent profile based on the perceived media device addiction of the children and parents was identified as three potential groups: Group 1 was average level of both children and parents, Group 2 was below average level of children and low level of parents, and Group 3 was above average level of children and high level of parents. Second, parents and child in group 2 were more likely to show higher maternal attachment and overall happiness scores but lower academic stress scores. In addition, children were in group 3 more likely to report high academic pressure and low autonomy. Third, children in group 2 reported higher self-regulated learning than children from group 1.
Conclusions This study suggests that there is necessary to receive information from both parents and children to accurately understand adolescents' addiction to media devices, and it implies that it is necessary to pay attention to maternal attachment, overall happiness, academic stress, autonomy, and achievement pressure to lower adolescents' addiction to media devices.

Objectives This study investigated the differences in overexcitability, grit, and creative self-efficacy between gifted and general students based on their preferences for art subjects.
Methods The study involved 77 gifted students and 43 general students in Seoul and Daejeon. The statistical analysis utilized SPSS 27, employing frequency analysis and multivariate analysis of variance (MANOVA) based on art subject preference.
Results Results indicate that, compared to general students, gifted students who prefer art subjects exhibit significantly higher levels of overexcitability and creative self-efficacy. Furthermore, when comparing gifted students and general students based on their art subject preferences, overexcitability, grit, and creative self-efficacy all show significant differences.
Conclusions These results suggest a correlation between art subject preference, overexcitability, and creative self-efficacy, emphasizing the interrelated nature of giftedness, overexcitability, grit, and creative self-efficacy.
A Narrative Study of a Chinese Scholar who Became a University Professor from Being Outdated in School Education

Published: January 2025

Objectives This study aimed to explore in-depth how a Chinese scholar experienced identity transitions in the process of growing from a school failure to a scholar. By analyzing a male scholar's experiences of rebuilding himself and overcoming academic setbacks from the perspective of transition theory, this study aimed to provide insights into the reconstruction of self-identity in the process of professional transition.
Methods Based on Schlossberg's transition theory, this study used a narrative research method to analyze the process of a Chinese scholar's identity reconstruction during a career transition. Through the four aspects of situation, self, support, and strategy, this study explored in-depth how he effectively utilized resources to break through his limitations during the life transition process.
Results The results of the study showed that the academic's career development went through several important transition stages. From failing a middle school exam to eventually becoming a doctoral program supervisor, each step was accompanied by complex challenges and identity reconstruction. This study found that an individual's resilience, adaptive capacity, and strategies for effectively utilizing social support systems in the face of academic failure are important factors that influence academic success.
Conclusions The study found that the transition from adolescent academic failure to successful university scholar was a dynamic, non-linear developmental process involving a series of “events” and “non-event” experiences. This process entailed an assessment of personal values and career goals, as well as the experience of interpreting and applying them in relation to social contexts such as social responsibility and status. Academic setbacks do not imply failure in academic careers, and education systems should focus on identifying policies and institutions that allowed individuals to develop their long-term potential, rather than temporary outcomes. This will require not only psychological and academic support at the individual level to overcome academic failure, but also detailed institutionalization of the social environment to turn failure into a resource for success.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Seungae , Ryu Ki-ung
Published: January 2025

Objectives The purpose of this study is to deeply explore the essence and meaning of the psychological burnout experiences of secondary school career guidance teachers.
Methods To achieve this, in-depth interviews were conducted with 10 career guidance teachers from middle and high schools between May and October 2024. The collected data were analyzed using phenomenological research method, which explores everyday experiences and elucidates their essential structures, to identify common experiences among the participants.
Results The analysis revealed five major themes: ‘Pressure from Uncomfortable External and Internal Gaze,’ ‘Struggling Against Distorted Perspectives,’ ‘Unique Psychological Pressure of Being a Career Guidance Teacher,’ ‘Anxiety in a Dual Position,’ and ‘Ongoing Burnout and Self-Reflection.’ Additionally, 13 sub-themes such as ‘Fish on the Chopping Board’ and ‘Self-Censorship and Internal Surveillance,’ and 35 meaning units including ‘A Position of Envy’ and ‘Subject of Curiosity’ were derived.
Conclusions This study examined in detail how career guidance teachers are situated in psychologically exhausting work environments, while also being viewed through the lens of ‘an easy position’ within the school. The findings provide foundational data to reduce the structural misunderstandings about career guidance teachers, enhance the understanding of their unique value and necessity, and ensure the establishment of a restorative occupational identity for career guidance teachers. The study contributes to raising appropriate awareness among school stakeholders.

Published: January 2025

Objectives The purpose of this study is to analyze the impact of a gifted education program on science interest and scientific attitudes among elementary and middle school students.
Methods A total of 130 students from 5th grade in elementary school to 9th grade in middle school in the Gyeonggi region participated in the STEM+I gifted education program. Pre- and post-surveys were conducted to measure changes in students' interest in science and their scientific attitudes. Data from 111 students were used in the final analysis.
Results Students who participated in the STEM+I program showed overall positive changes in their interest in science and scientific attitudes. First, there was a significant increase in interest in science itself. Notably, the science interest of female students increased significantly, eliminating the gender gap that was present before the program. Second, there were significant improvements in curiosity, openness, task commitment, and creativity, particularly among female students for openness, cooperation, and creativity, and among middle school students for curiosity, openness, cooperation, and task commitment.
Conclusions This study demonstrates that gifted education programs have a positive impact on general students' interest in science and scientific attitudes. This provides important evidence for the potential applicability of gifted education programs to general students and the need for diverse educational approaches.
