Semantic Textual Similarity (also known as Semantic Short-text Similarity) is a research problem that aims to calculate the similarity among text units (phrases, sentences, paragraphs or texts) focusing on the semantic content. The importance of Semantic Similarity in Natural Language Processing has increased in the last years due to its relevance in many tasks and applications, such as Automatic Summarization, Machine Translation, Question Answering or Semantic Indexing. UB-NER is a self-contained Java software library for benchmarking state-of-the-art STS measures in the biomedical domain. It allows to define and execute a set of experiments combining different measures and preprocessing methods. This dataset contains the reproducibility framework and dependencies, whose aim is to allow the exact replication of unsupervised named entity recognition experiment in the biomedical domain as detailed in "ReproductionProtocol.pdf" file.

This data set includes the associated data to the characterization results of the samples by different techniques: XRD, TG, SEM and TEM.

Descripción del proyecto

Este estudio analiza si los niños de (5 a 11 años) atribuyen más envidia maliciosa (schadenfreude) o benigna cuando la situación es de ganancia o pérdida para el envidioso. Además estudiamos si la ventaja (ganada o perdida) se ha obtenido merecida o inmerecidamente. Además analizamos las justificaciones verbales de sus respuestas. Se trata de un diseño factorial mixto y se controla la edad y el sexo en todas las condiciones. Utilizamos viñetas para representar a los personajes en las diferentes condiciones experimentales. Los resultados obtenidos indican que cuando el envidioso obtiene una ganancia gracias a la pérdida de la ventaja del envidiado (razonamiento de suma cero) los niños atribuyen una intensidad más alta de schadenfreude (envidia maliciosa) mientras que cuando el envidioso no obtiene ninguna ganancia (hay igualdad entre ambos personajes) la envidia benigna aparece más frecuentemente y hay una disminución de la schadenfreude. En cuanto a la merecimiento de la ventaja, solo es considerada por los niños mayores y solo en la condición de pérdida. Prevalece más el razonamiento de suma-cero más que el merecimiento a la hora de atribuir envidia maliciosa y benigna.,

In this work, the Rh-promotion to transition metal (Ni and Co) CeO2-supported catalysts has been studied for the first time on the acetic acid oxidative steam reforming. Characterization of the prepared catalysts confirmed the promoting effect of rhodium addition, allowing lower crystallite size which increases the number of available active sites to reactants, along with higher reducibility as evidenced by temperature-programmed reduction (H2-TPR). The influence of the reaction temperature on the acetic acid conversion and hydrogen yield was assessed. Co-based catalysts achieved better catalytic performance than Ni-based samples, almost complete acetic acid conversion, and hydrogen yields were close to the equilibrium values at temperatures over 500 ºC. On the other hand, tests at higher weight-hour space velocity evidenced the superior activity of Co-Rh/CeO2 sample. This sample showed good stability with almost complete acetic acid conversion after 25 h time-on-stream, decreasing only the hydrogen yield by 7% after the first 8 h along with a slight increase in the acetone yield of about 6%. This suggests that after the acetic acid ketonization, acetone steam reforming advanced to a lesser extent on the reaction mechanism because of long-term slight catalyst deactivation.

This 1550-1590 time series was reconstructed according to the intensity and significance of the meteorological data collected in historical archives and subsequently, assigning to them an ordinal index of intensity, ranging from + 4 to – 4. A reference series from 1960-90, belonging to a meteorological station situated in the area was used to convert the ordinal index into temperatures.

This dataset contains the data related to the article "Comparing a LEGO® Serious Play Activity With a Traditional Lecture in Software Engineering Education" with DOI 10.1109/ACCESS.2024.3403504. This dataset contains data of 227 software engineering students, 110 of which belonged to the control group while the other 117 were part of the experimental group. The first tab of the file contains pre-test and post-test scores, and the resulting Learning gain for each student, whereas the second tab of the file contains the results of a perceptions questionnaire with 9 items (2 items were only fullfilled by students of the experimental group). All data was anonymized so that the identity of the participants cannot be ascertained. The aforementioned article can be openly accessed at https://doi.org/10.1109/ACCESS.2024.3403504.

This study advance research on the think manager–think male paradigm by analysing the influence of performance information (success vs. failure), on task- and relationship-oriented leadership styles, and on three evaluative and behavioural measures. ased on the theoretical framework of think manager–think male, the present study examines the extent to which information about successful or failed company performance affects: (a) leadership styles (task and relationship), (b) overall assessment of male and female leaders, (c) assignment of responsibility for the results, and (d) disposition to replace male and female leaders. In a quasi-experimental study (N = 106 workers) with a 2 (success vs. failure) x 2 (male vs. female leader) design the aforementioned variables were analyzed. Results show that company performance has an impact on all outcome variables. However, this pattern affects male leaders in a different way than female leaders. Overall, male leaders are assessed more or less positively, depending on the outcome of performance results. For female leaders, company performance has no significant impact on perceptual (task- and relationship-oriented leadership style) and behavioral (replacement) measures, but it does on evaluative measures (performance assessment and attribution of responsibility), although to a lesser extent than for male leaders. In sum, performance assessment is influenced not only by company performance but also by the gender of the manager. Overall, men receive better evaluations than women in the success condition, but their evaluation is worse in cases of failure. These results fit with gender stereotypes; more power is attributed to men, who are considered more responsible for company results. This does not happen in the case of women managers who are perceived as less responsible for successes and failures.

A miniaturized and environmentally conscious analytical workflow was developed and validated for the extraction, purification, and quantification of major glycoalkaloids ( α-solanine, α-chaconine), the degradation product γ-chaconine, and the aglycone solanidine in potato-based snack products. The method combines ultrasound-assisted extraction (UAE) with pipette-tip solid-phase extraction (PT-SPE), followed by UHPLC-MS/ MS analysis. UAE conditions were optimized using a Box-Behnken statistical design, which evaluated the extraction time, ultrasound amplitude, and solid:liquid (SL) ratio. Optimal conditions were determined to be 5 min, 100 % amplitude, and a 1:9 w/v of SL ratio, with methanol as the most effective extraction solvent. MSU-2- C18 mesostructured silica sorbent, packed into pipette tips (5 mg) connected to a SPE vacuum manifold (VMA- PT-SPE), was employed under the optimized conditions to simultaneously purify up to 12 extracts. The method’s greenness was evaluated using the AGREEprep metric, yielding a score of 0.65, indicating good environmental performance. Limits of detection (LOD) and quantification (LOQ), ranging from 0.55–4.40 µg/kg and 1.82–14.67 µg/kg, respectively, were achieved for the target analytes. Application to four commercial potato-based snacks revealed major ( α-solanine and α-chaconine) and minor glycoalkaloids (γ-chaconine and solanidine) levels, ranging from 2.0 to 16.0 mg/kg fresh weight, highlighting substantial variability among products and providing a more comprehensive characterization of the glycoalkaloid profile. Compared to conventional SPE formats, this UAE-VMA-PT-SPE strategy offers superior reproducibility while reducing sample and solvent consumption. The method represents a powerful tool for routine monitoring of glycoalkaloids in potato snacks, supporting food safety assessments and addressing analytical priorities established by the European Food Safety Authority.
