Intangible assets and capital structure in emerging markets: evidence from Thai-listed firms

An analysis of 716 Thai-listed nonfinancial firms, covering 7,702 firm-years from 2005-2022, found reported intangible assets positively associated with leverage, especially among high-tangibility and manufacturing firms. This challenges the assumption that intangibles always constrain debt capacity, but remains observational.

Clinicopathological characteristics and clinical outcomes of multiple histological subtypes in feline mammary carcinomas

A retrospective cohort of 87 cats found papillary tubular and tubulopapillary carcinomas more often at earlier stage with lower proliferation markers, while no-special-type carcinomas had the poorest prognosis. Stage, grade, margins and subtype were associated with survival. The findings inform veterinary pathology but require external validation.

The neuroimaging correlates of depression established across six large-scale population datasets

Across six population neuroimaging datasets and 23,417 participants, depression was associated with lower grey-matter volume and cortical surface area in frontal, anterior cingulate and insular regions, plus somatomotor and visual network patterns. No consistent subcortical correlates emerged. Cross-dataset evidence strengthens group-level inference but is not an individual diagnostic tool.

Wolfy Badges and Leader Boards: The Impact of Gamification on Motivation and Vocabulary Learning in Vocational College English Classes

A five-week vocational EFL classroom study compared 21 gamification students with 22 controls. Both groups improved, and adjusted post-test scores favoured gamification, but the experimental group's delayed scores declined, indicating a retention challenge.

A Mixed-Method Needs Analysis for Developing In-Flight Communicative English Material Integrating Intercultural Communicative Competence from Thai University Students' Perspectives

A survey of 265 airline-business students and interviews with 12 participants prioritized real-time speaking and listening, safety communication, conflict management and intercultural competence. Results support scenario and role-play materials but represent student needs, not tested material effectiveness or workplace performance.

Development and psychometric validation of a teacher feedback literacy test for student teachers

Researchers developed a 20-item situational multiple-choice test of teacher feedback literacy and administered it to 552 Thai student teachers. The design, relational and pragmatic domains showed reported item, construct and internal-consistency evidence, but test performance is not equivalent to giving and using feedback in practice.

Engineered Yolk–Shell Nanocarriers for Biphasic Release and Efficient Codelivery of Chemotherapy Drugs in Lung Cancer Cells

A yolk-shell nanocarrier was engineered to co-deliver doxorubicin and paclitaxel from separate compartments for rapid and sustained release. In A549 cells, comparable or greater cytotoxicity was reported at substantially lower loaded drug amounts. Evidence remains in vitro, without animal or human safety, distribution or efficacy data.

Potent Anti-adipogenic Activity of Cyclopeptide Mallotumide A on Murine 3T3-L1 Adipocytes

At 1 nM, the cyclopeptide Mallotumide A reduced lipid accumulation and adipogenic-regulator expression in murine 3T3-L1 cells, without major apoptosis or mitochondrial impairment in mature adipocytes. Because this concentration is near the precursor-cell IC50, differentiation inhibition must be distinguished from cytostatic effects.

Accessible remote sensing of bridge movement monitoring with UAV-based SfM photogrammetry and unsupervised machine learning

A remote bridge-assessment framework combines UAV imagery, Structure from Motion point clouds and RANSAC-based region extraction, comparing M3C2, C2C and C2M for translation, rotation and settlement. Experiments report high accuracy and efficiency, but the abstract provides no error values or real post-disaster deployment evidence.

Ageism Toward Older Adults Among Thai High School Students: A Cross-Sectional Study

Among 301 high-school students in Wang Thong district, the Fraboni Scale classified 86.7% at moderate and 3.0% at high ageism. Several items reflected stereotypes about social life, rights and creativity, while measured personal and family factors showed no association. The findings support intergenerational education, not labelling individual students.

Engagement audit partner–CFO joint tenure and audit fees: evidence from Thailand

Across 262 Thai-listed nonfinancial firms and 1,492 firm-years from 2016-2021, longer joint tenure between the engagement audit partner and CFO was positively associated with audit fees, including within-firm changes. The pattern may reflect client-specific knowledge, complexity or bargaining, but does not establish improved audit quality.

Doing Great by Doing Good: The Impact of Corporate Social Responsibility on Knowledge Acquisition Through Foreign Subsidiaries

An empirical analysis of 135 US pharmaceutical firms and 3,393 subsidiaries from 2013-2020 supported the view that CSR builds legitimacy and local embeddedness associated with foreign knowledge acquisition. CSR also weakened the negative relationship between financial/operational efficiency and knowledge activity. These are US-firm data, not Thai corporate outcomes.
