Machine-derived sentiment analysis has become a pervasive and useful tool to address a wide array of issues in natural language processing. Leading technology companies such as Google now provide sentiment analysis tools (SATs) as readily accessible online products. Academic researchers develop and make available SATs to support the research enterprise. One of the major challenges with SATs is the inconsistencies in results among the various SATs. Consequently, the selection of a SAT for a specific purpose may significantly impact the application. This study addresses the foregoing problem by utilizing structural equation modeling to merge the outputs of SATs to develop a combined sentiment metric without the need for a labeled training dataset. This method is applicable to a wide range of text-based problems, is data-driven, and replicable. It was tested using three publicly available datasets and compared against seven different SATs. The results indicate that as a continous measure, the proposed method outperformed other SATs in the movie reviews and SemEval datasets, and achieved a tie for first place with IBM Watson on the Sentiment 140 dataset. Also, compared to the published major alternatives, the arithmetic mean solution, this approach performed better across these three datasets.

Despite the burgeoning adoption of informal learning in people's daily lives, the actual effects of informal learning activities, especially technology-related informal learning activities, are much less reported than those of formal learning. Furthermore, there is a notable lack of research on the effects of technology-related informal mathematics learning activities (TRLA). This study aims to propose and validate a new model which illustrates the effects of TRLA on four constructs: mathematics self-efficacy (MSE), mathematics interest (MI), self-regulation in mathematics learning (SR), and teacher-student relationship (TSR). Adopting a quantitative cross-sectional survey approach, 460 students were investigated. The data were analyzed employing two-step structural equation modeling. Our findings demonstrate the direct effects of TRLA on MI and SR as well as the indirect effects on MI, MSE, and TSR. This study advances the understanding of technology-enhanced informal learning, which is an emerging perspective of technology-enhanced learning.

Researchers interested in the quantitative analysis of data from dyads must select a preferred statistical framework. In this review, we focus on one option that has seen relatively modest adoption: dyadic structural equation modeling with latent variables. We begin by distinguishing dyadic SEM from alternate, neighboring, and hybridized frameworks, before sharing our view on the unique-and in our opinion, considerable-value-proposition of the dyadic SEM framework. We then provide some preliminary evidence that dyadic SEM is subordinated in terms of adoption rates versus its competitors, before offering a contextual analysis of why that may have come to be the case. Finally, we conclude with a discussion of future possibilities, some near and accessible and others farther away and more technical, that researchers in the field might pursue (and benefit from) with the help of dyadic SEM with latent variables.

This study presents a method to assist airlines in selecting a hub airport using structural equation modeling (SEM) combined with Analytic Hierarchy Process (AHP). This approach aims to determine the most essential elements in this selection process using observed variables collected from 300 major airports worldwide. Research on key aspects for hub airport selection is still scarce in the literature. Furthermore, most studies rely on multicriteria analyses with weights obtained through expert interviews, potentially introducing subjectivity. Therefore, this paper presents a unique approach: criteria and sub-criteria values in the AHP are determined by the results achieved in the SEM, providing a reliable scale of priorities among variables in the process of choosing a hub. The SEM tested two hypotheses that were supported by comparing two latent variables related to airport and region characteristics with another latent variable referring to aspects present in the activity of the dominant airline within each facility. Subsequently, an AHP was implemented, with criteria and sub-criteria weights based on the standardized loading factors and regression coefficients from the SEM, using sets of airports for each established world region in the study. Results indicated that airport characteristics, particularly those related to the passenger terminals, have a greater influence on the main carrier activity than region characteristics. A regional analysis revealed that in the Americas, Europe, the Middle East, and Africa, this predominance is even more pronounced, whereas in Asia-Pacific region, there is a contrary trend in which the socioeconomic factors of the city appear to be more important than airport infrastructure. The weights assigned in the AHP, based on SEM values, confirmed cohesion between the two stages of the proposed model.

The relational nature of cultural humility (CH) has been evident since the beginning of its conceptual and empirical explorations in multicultural counseling. However, few studies have intentionally used a theory-driven framework to examine the relational processes of CH. In the current study, we used a structural equation modeling approach to examine the relationships between CH, empathy, therapeutic working alliance, and real relationship through a common factors framework. Using a sample of 610 adult counseling clients, we found that CH accounted for approximately 60% of the variance in the working alliance and 58% of the variance in the real relationship. Moreover, we found that empathy partially mediated the dispositional and situational effects of CH on both relational outcomes. We discussed strategies to cultivate CH in counseling relationships. We also recommended future researchers identify other theoretically related mediators and moderators.

Artificial intelligence (AI) integration in education has grown significantly recently. However, the potential risks of AI have led to educators being wary of implementing AI systems. To discover whether AI systems can be effective in the classroom in the future, it is critical to understand how risk factors (e.g., perceived safety risks, perceived privacy risks, and urban/rural differences) affect pre-service teachers' AI acceptance. Therefore, the study aimed to (1) explore the influence of perceived risks and AI trust on pre-service teachers' intentions to use AI-based educational applications, and (2) investigate possible variations in potential determinants of their intentions to use AI based on urban-rural differences. In this study, data from 483 pre-service teachers in China (262 from rural areas) were obtained by survey and analyzed using confirmatory factor analysis (CFA) and structural equation modeling-based multi-group analysis. The study's findings demonstrated that while AI trust influenced pre-service teachers' AI acceptance, the effect was less pronounced than perceived ease of use and perceived usefulness. Most notably, findings showed that perceived privacy and safety risks negatively influence AI trust among pre-service teachers from rural areas, which was a trend not observed in pre-service teachers from urban areas. As a result, to integrate AI-based applications into educational settings, pre-service teachers believed that the AI system must be functionally robust, user-friendly, and transparent. In addition, urban-rural differences considerably affect pre-service teachers' AI acceptance. This study provides further relevant recommendations for educators and policymakers.

Background and aims: Dysphagia is significantly correlated with prognostic outcomes in patients with stroke;however, the intrinsic mechanism of action between the two remains unclear. This study aimed to model the intrinsic mechanism of action between dysphagia and prognostic outcomes in patients with stroke based on structural equation modeling. Methods: A retrospective analysis of 900 inpatients with stroke from three large hospitals was performed. AMOS software (version 23.0) was used to construct the structural equation modeling. Results: The overall model showed a good fit (chi-square = 27.3, root mean square error of approximation = 0.01, standardized root mean square residual = 0.032, comparative fit index = 0.98, and adjusted goodness of fit = 0.94). structural equation modeling showed that the total effect of dysphagia on the prognosis of patients with stroke was 0.694, with a direct effect of 0.599, accounting for 86.31 % of the total effect. The total indirect effect was 0.095, with the mediating effects of serum albumin level and pneumonia accounting for 6.48 % and 7.35 % of the total effect, respectively. The moderating effects of sex on dysphagia and the relationship between activities of daily living, modified Rankin scale score, and length of hospital stay were insignificant (DR2 = 0.063, P = 0.145;DR2 = 0.002, P = 0.620;DR2 = 0.001, P = 0.307). Conclusions: Dysphagia can directly affect the prognostic outcomes of patients with stroke and indirectly affect prognosis by triggering pneumonia and lowering albumin levels. Sex was not found to play a moderating role in the relationship between dysphagia and prognosis. (c) 2024 European Society for Clinical Nutrition and Metabolism. Published by Elsevier Ltd.

This study examines the effects of trainee reactions on perceived training utility and trainee course satisfaction and tests the effect of utility reactions on trainees' satisfaction with training. 171 civil service officers participated in this study. The responses were analyzed using the Partial Least Square Approach of structural equation modeling. The results support the proposed hypotheses, suggesting that both positive training reactions and utility reactions affect trainees' satisfaction with the training. Also, while all reaction components are predictive of utility reactions and trainee satisfaction, the perceived usefulness of training has the most significant effect. This study has implications for policymakers on both a theoretical and practical level, given their roles in designing training programs and imparting them to civil servants. This paper extends management perspectives on training evaluation by examining the relationship between trainee reactions, utility reactions, and trainees' satisfaction. Practical implications and directions for further research are also discussed. Relevance, usefulness, and consistency of training material alleviate participants' level of ***' positive reaction to training significantly predicts satisfaction with the training program/courseThe capacity and capability of trainers affect trainees' reactions.

Blended collaborative learning has emerged as an effective pedagogical model that integrates face-to-face and online learning environments, offering a dynamic platform for deep learning-characterized by critical thinking, knowledge synthesis, and application. However, existing research offers mixed findings on how blended collaborative learning promotes deep learning, with little focus on the integrated roles of learner engagement (LE), self-regulated learning (SRL), and group interaction (GI). This study addresses this gap by developing and testing a structuralequation model to explore the interplay between LE, SRL, and GI and their collective impact on deep learning outcomes. A sample of 450 learners from higher education institutions participated in this study, which used validated survey instruments to assess these constructs. The findings indicate that LE significantly influences deep learning both directly and indirectly through SRL and GI. SRL and GI were also found to sequentially mediate the relationship between LE and deep learning, underscoring the importance of both individual self-regulation and collaborative interaction in fostering deep learning in blended collaborative learning environments. Additionally, gender differences in these relationships were explored, revealing subtle variations in learning dynamics between male and female learners. The study contributes to the theoretical understanding of blended learning environments and offers practical implications for designing educational frameworks that promote meaningful and lasting learning experiences.
