This dataset accompanies the IJIES manuscript "Knowledge-Sharing Behavior on Facebook Using Theory of Planned Behavior" (Yuliazmi et al., 2026). CONTENTS It contains an anonymized derived-feature dataset of 1,841 lengthy Facebook posts from 81 Indonesian Facebook users. Each post is described by 21 numeric/categorical features (S1-S21) derived from the Theory of Planned Behavior (TPB) framework and labelled as either Knowledge-Sharing Content (KSC) or Non-Knowledge-Sharing Content (NKSC). The package also provides 80/20 train/test split indices and StratifiedGroupKFold (k=5) user-grouped fold assignments for cross-user validation. Selected hyperparameters for six classifiers (Logistic Regression, Random Forest, Gradient Boosting, SVM, Neural Network, CatBoost) and the random seed (42) are included. A README maps each manuscript table (Tables 7-14) to the files and pseudocode steps required to reproduce it. DATA COLLECTION - Survey (OSMS): online questionnaire distributed between January 27 and April 2, 2021. 345 valid respondents. - Facebook posts: retrieved between March and June 2021 from public timelines of 184 participants who indicated consent through the online survey to share their Facebook activity for research. Retrieved posts span Dec 1, 2019 - Apr 8, 2021 (16-month historical window). Of 184 consenting participants, 81 met the post-length criterion (>= 5 sentences/post), yielding 1,841 lengthy posts. ANONYMIZATION & ETHICS Participants provided informed consent through the online survey, including specific agreement to share their public Facebook posts for research. The dataset has been fully anonymized: raw text, usernames, profile links, URLs, and timestamps removed; user IDs replaced with codes (vr###). Original posts cannot be reconstructed or re-identified. Anonymization is consistent with Indonesia's Personal Data Protection Law (UU PDP No. 27/2022). HISTORICAL CONTEXT The 2021 retrieval reflects the platform access environment of that period; current Facebook policies differ substantially. INTENDED USE & CITATION Released under CC BY 4.0. May be used for the analyses in the accompanying paper as well as new investigations into knowledge-sharing behavior, social media classification, or TPB feature engineering. Please cite both the dataset and the accompanying paper. Keywords: Theory of Planned Behavior, knowledge sharing, social media, Facebook, machine learning, Indonesian dataset, classification.

This repository contains the dataset supporting the systematic literature reviews and thematic analyses conducted in this study on the evolution of eco-efficiency and its relationship with the circular economy. The dataset is provided in a single Excel file organized into two separate sheets corresponding to two systematic literature reviews (RSLs). The first sheet (RSL1) contains the academic publications analyzed for the historical review of eco-efficiency and its conceptual evolution between 1987 and 2014. The dataset includes selected scholarly articles classified according to analytical and thematic categories used to examine the changing interpretations, applications, and sustainability orientations associated with eco-efficiency across different historical periods. The second sheet (RSL2) contains the literature analyzed to examine the relationship between eco-efficiency and the circular economy between 2007 and 2023. This dataset includes selected academic publications coded according to thematic and analytical categories related to circular economy principles, sustainability transitions, organizational approaches, and conceptual intersections with eco-efficiency. Both datasets include bibliographic information, classification criteria, thematic coding, and interpretative analytical notes used to support the identification of conceptual developments, thematic patterns, convergences, and gaps within the literature.

The impact of financial development and institutional quality on the environment

This contribution compiles the problems, solutions and results of the Cuban National Chemistry Contest (CNQ) for high school students celebrated nationwide this year. This chemistry olympiad is a yearly competition that stimulates high school students to study chemical sciences during their bachelor's. It is sponsored by the Cuban Ministry of Education, the Cuban Society of Chemistry, the University of Havana and other institutions. Tenth-, eleventh- and twelfth-graders (15-18 years old, on average) are welcome to participate. It takes place in every province of the country at the Vocational High School for Exact Sciences (IPVCE). It is organized as a two-day competition in which the students try to solve two sets of theoretical or theoretical-practical problems elaborated by previous contestants and mentors. The problem sets have both common questions for two or three grades and individual questions. The highest scores are priced with gold, silver and bronze medals. Top winners are part of the national pre-selection and are invited to Havana for a short training period. After a final selection round, the national team for the international chemistry olympiads is formed. This year, the CNQ took place on February 19 and 20. The qualification of the exams was performed in Havana by a committee composed of selected students and mentors from the University of Havana. Herein, the problem sets of the Preparatory Problems booklet, the national exams and their solutions, and the results of the Cuban students in the national and international competitions of the previous year are provided in the official Spanish version and English translation.

This dataset contains all raw computational data, electronic structure results, and analysis files associated with the publication. This dataset supports a systematic density functional theory (DFT) investigation of the adsorption of 22 chemical species — including carbonate-based electrolyte solvents (EC, PC, DMC, DEC, EMC), sodium salts (NaClO₄, NaPF₆, NaFSI), gas-phase decomposition products (CO₂, CO, C₂H₄, SO₂, HF), and solid electrolyte interphase (SEI) components (NaF, NaCl, Na₂O, Na₂S, Na₂CO₃, Na₂SO₃, CH₃ONa, C₂H₅ONa, CH₃OCO₂Na) on a defective Na(110) surface model incorporating a pyramidal Na₅ adatom cluster and a multi-atom Na vacancy (5V_Na), within a 4×3 supercell. The data are organized into the following categories: 1. bulk_phase: Bulk bcc Na structural optimization (lattice parameter, energy). 2. Pristine and defective Na(110) 4×3 slab models (surface energy, work function, ECN, DDEC charges, dos). 3. Gas-phase optimizations of all 22 chemical species (binding energies, bond geometries). 4. Lowest-energy adsorption configurations of all 22 species on the defective Na(110) surface (adsorption energies, interaction energies, deformation energies, ddec charges, dos, rmsd, work function, ecn, cdd) and also multiple adsorption sites configuration.

This study adopted a quantitative research design and employed a structured questionnaire as the primary data collection instrument. All measurement items were adapted from previously validated English-language scales and operationalized using a 5-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). The questionnaire was administered in Turkish, and a translation–back translation procedure was applied by professional translators, followed by researcher review to ensure linguistic and conceptual equivalence. The target population consisted of domestic tourists visiting the province of Kars, Türkiye. A pilot study was conducted in February 2025 with 50 respondents selected via convenience sampling; the results indicated no need for item revision. Data were collected between February and April 2025 using both face-to-face and online survey methods. Of the 600 questionnaires distributed, 450 were returned. After data screening procedures (including missing data treatment and outlier analysis), 341 valid responses were retained for analysis. The questionnaire comprised two sections: the first measured the three main constructs of the study (see references in Table 1) and the second collected demographic information. Data were coded and initially analyzed using SPSS 20 for descriptive statistics and data cleaning, and subsequently transferred to SmartPLS 4.1 for Partial Least Squares Structural Equation Modeling (PLS-SEM). The measurement model was evaluated using indicator loadings, composite reliability (CR), average variance extracted (AVE), and discriminant validity criteria (Fornell–Larcker and HTMT). Bootstrapping procedures were then applied to test the structural relationships and hypotheses. The results indicate that local food consumption motivations have a significant positive effect on intention to recommend and on perceptions of socio-cultural sustainability. In turn, socio-cultural sustainability perception significantly and positively influences intention to recommend. Moreover, local food consumption motivations significantly moderate the relationship between socio-cultural sustainability perception and intention to recommend.
