Getting Docking into Shape Using Negative Image-Based Rescoring
2019
The failure of default scoring functions to ensure virtual screening enrichment is a persistent problem for the molecular docking algorithms used in the structure-based drug discovery. To remedy this problem, elaborate rescoring and post-processing schemes have been developed with a varying degree of success, specificity, and cost. The negative imagebased rescoring (R-NiB) has been shown to improve the flexible docking performance markedly with a variety of drug targets.The yield improvement is achieved by comparing the alternative docking poses against the negative image of the target protein’s ligand-binding cavity. In other words, the shape and electrostatics of the binding pocket is dir…
Parental communication and feelings of affiliation in adolescent aggressors and victims of cyberbullying
2018
Cyberbullying is an increasingly frequent problem among adolescents, and it produces considerable social concern. Using a cross-sectional and quantitative methodology, the main objective of this study was to analyze the differences among students involved in the perpetration and victimization of cyberbullying (non-involved, occasional, and severe), in their parental communication, and feelings of affiliation with classmates. The sample consisted of 849 adolescents (51.7% boys and 48.3% girls) from 12 to 18 years old (M = 14.5
Simone de Beauvoir on Sexual Difference
2018
In the introduction to The Second Sex, Simone de Beauvoir clarifies her philosophical approach to embodiment and sexual difference by writing: “However, it is said, in the perspective which I adopt—that of Heidegger, Sartre and Merleau-Ponty—that if the body is not a thing, it is a situation: it is our grasp upon the world and an outline of our projects.”
Mixed Methods Research in Music Therapy
2015
Mixed Methods Research (MMR) combines different research methodologies in the same study with the goals of producing better and more profound knowledge of the phenomenon under investigation than use of a single method would achieve. Typically, both quantitative and qualitative approaches are employed in MMR. Music therapy is an example of a complex research area, where MMR can be considered a suitable way to capture and reflect the complexity of practice. There are many ways to understand and conduct MMR and the field is developing quickly. The chapter briefly describes MMR and its latest developments using examples of music therapy research in which MMR has been applied. Though MMR is a we…
ICT adoption in hotels and electronic word-of-mouth
2015
Purpose The purpose of this paper is to investigate how information and communication technology (ICT) adoption in hotels contributes to satisfaction and loyalty from the consumer perspective, considering the online dimension of recommendations. Design/methodology/approach A quantitative research based on a structured questionnaire and using a personal survey method was developed. Surveys were conducted on 386 guests from Spanish hotels. Causal methodology by testing structural equation model was applied. Findings Significant relationships are obtained in the sequence “ICT use perception – satisfaction with ICT – overall satisfaction with the hotel – dimensions of loyalty” and the mediatin…
Chronic obstructive lung disease “expert system”: Validation of a predictive tool for assisting diagnosis
2018
Purpose: The purposes of this study were development and validation of an expert system (ES) aimed at supporting the diagnosis of chronic obstructive lung disease (COLD). Methods: A questionnaire and a WebFlex code were developed and validated in silico. An expert panel pilot validation on 60 cases and a clinical validation on 241 cases were performed. Results: The developed questionnaire and code validated in silico resulted in a suitable tool to support the medical diagnosis. The clinical validation of the ES was performed in an academic setting that included six different reference centers for respiratory diseases. The results of the ES expressed as a score associated with the risk of su…
Instruction-based clinical eye-tracking study on the visual interpretation of divergence : how do students look at vector field plots?
2018
Relating mathematical concepts to graphical representations is a challenging task for students. In this paper, we introduce two visual strategies to qualitatively interpret the divergence of graphical vector field representations. One strategy is based on the graphical interpretation of partial derivatives, while the other is based on the flux concept. We test the effectiveness of both strategies in an instruction-based eye-tracking study with N = 41 physics majors. We found that students’ performance improved when both strategies were introduced (74% correct) instead of only one strategy (64% correct), and students performed best when they were free to choose between the two strategies (88…
Acoso escolar y Educación Física: una revisión sistemática (Bullying in schools and Physical Education: A systematic review)
2018
El objetivo de este trabajo es realizar una revisión sistemática de estudios sobre acoso escolar y Educación Física (EF). Se identifican, categorizan y analizan los artículos señalando sus características y sintetizando los principales temas de investigación y su contenido. Para ello, se ha consultado la base de datos Web of Science®. Se seleccionaron un total de 19 artículos científicos. Respecto al análisis documental, se presentan hallazgos sobre revistas más productivas, autores e instituciones con mayor actividad investigadora en este campo y metodología de investigación utilizada en los estudios encontrados. Además, se hace un análisis cualitativo centrado en el contenido de los 4 tem…
Aqueous enzymatic process assisted by microwave extraction of oil from yellow horn (Xanthoceras sorbifolia Bunge.) seed kernels and its quality evalu…
2013
Abstract In this study, aqueous enzymatic process (AEP) assisted by microwave extraction (ME) of oil from yellow horn ( Xanthoceras sorbifolia Bunge.) seed kernel was investigated. Central composite design (CCD) and response surface methodology (RSM) were used to optimise an enzyme cocktail (cellulase, hemicellulase, pectinase) for AEP. The main factors of ME were also studied. A maximal oil extraction yield of 55.8% was achieved under optimal conditions. Moreover, scanning electron microscope (SEM) was applied to characterise the extraction process. Analysing chemical composition of the extracted oil by GC–MS showed that the content of unsaturated fatty acids by this emerging method (91.18…
