The objective of this article is to develop virtual tours in three dimensions (3D) of the Chemistry laboratories of the Technological University of the Southeast of Veracruz (UTSV). For its progress, it was carried out: analysis, selection, training, design, development and integration of software and hardware tools. The same ones that were necessary for the development of virtual reality on 3D modeling of the General Chemistry, Instrumental Analysis and Chemical Plants laboratories, achieving a product that would allow university students to be approached virtually, and thus be able to know the spaces and devices located in each laboratory, where it presents the description of the operation of each of the equipment, by means of multimedia effects accompanied by an avatar within the virtual tour. Finally, the final result was evaluated with a group of students with the support of the Chemistry teachers and knowledgeable about the laboratory spaces, where the degree of acceptance and perception was obtained as a consequence through a survey carried out.

AbstractRecent events in the workplace, government, and college campuses in the US have brought the issues of sexual harassment and assault to the forefront of media and public discussion. Industrial and organizational (I-O) psychologists are uniquely suited to help address these issues by aiding in intervention development. Specifically, I-O psychologists can provide key insight regarding the context, design, development, and evaluation of sexual harassment and assault training efforts. Although some empirical evidence suggests that trainings are effective in the short term, there is little evidence to suggest long-term attitudinal or behavioral change outside of the training environment. Much of the research in this area, however, has focused solely on the training intervention, excluding the pre- and post-training environment. Thus, the present effort focuses on designing trainings that promote transfer, as well as improving measurement of desired outcomes, to provide a framework for improving sexual harassment and assault training. This framework addresses how individual differences, needs analysis, training design, evaluation, and post-training support contribute to lasting change while addressing the unique challenges associated with sexual harassment and assault. Last, this framework provides guidance for improving research in this area as well as practical suggestions for improving training programs.

Urban modeling and visualization are highly useful in the development of smart cities. Buildings are the most prominent features in the urban environment, and are necessary for urban decision support; thus, buildings should be modeled effectively and efficiently in three dimensions (3D). In this study, with the help of Gaofen-7 (GF-7) high-resolution stereo mapping satellite double-line camera (DLC) images and multispectral (MUX) images, the boundary of a building is segmented via a multilevel features fusion network (MFFN). A digital surface model (DSM) is generated to obtain the elevation of buildings. The building vector with height information is processed using a 3D modeling tool to create a white building model. The building model, DSM, and multispectral fused image are then imported into the Unreal Engine 4 (UE4) to complete the urban scene level, vividly rendered with environmental effects for urban visualization. The results of this study show that high accuracy of 95.29% is achieved in building extraction using our proposed method. Based on the extracted building vector and elevation information from the DSM, building 3D models can be efficiently created in Level of Details 1 (LOD1). Finally, the urban scene is produced for realistic 3D visualization. This study shows that high-resolution stereo mapping satellite images are useful in 3D modeling for urban buildings and can support the generation and visualization of urban scenes in a large area for different applications.

Background In Spain, palliative care (PC) nursing is not a recognized specialization and PC nurses do not receive systematic specialized academic training in PC. To ensure the quality of PC in Spain, the Spanish Association of Palliative Care Nursing has been working since 2011 to design a model of competencies for PC nurses. Objective: Verify whether a sample of Spanish PC nurses accepts the proposed model of PC nursing competencies describing their work. Methods: Descriptive cross-sectional observational study based on an ad-hoc questionnaire about 98 proposed competencies, which participants rated for whether they belong to the purview of PC nurses and for their degree of concordance with their own practice and their degree of importance in PC nursing. Competencies receiving approval by more than 75% of participants for the three dimensions were considered to have been accepted by consensus. Mixed logistical models were developed to study the association between demographic variables and the responses. Results: Sixty-two out of 98 proposed competencies were accepted by more than 75% of participants. We therefore considered these competencies to have been accepted by consensus. Thirty-six proposed competencies failed to meet the threshold of 75% acceptance. For competencies that were accepted overall, participants with more than 10 years of experience in PC and participants with specialized training in PC were more likely to report that these competencies were part of the purview of PC nursing. Participants age >50 were less likely to report that competencies related to research concorded with their practice. Participants accepted the importance of all 98 proposed competencies. Conclusion: The variables of experience, training and age had a statistically significant relationship with the acceptance or rejection of the proposed competencies on the basis of purview and concordance. Further research is necessary to understand more fully these relationships to eventually arrive at a consensus model for the competencies of PC nurses.

This research focuses on chemistry teachers’ enacted pedagogical content knowledge (ePCK) in equilibrium in chemical reactions. The enactment dimension of this pedagogical content knowledge (PCK) encompasses enacted knowledge and skills as well as those embedded in practice concerning the Refined Consensus Model of PCK, the most recent PCK model in science education. As ePCK plays out throughout the whole pedagogical cycle, it was conceptualized as to exist in three forms, such that ePCKP, ePCKT, and ePCKR. While ePCKP and ePCKR represent the knowledge and skills that a teacher uses for planning and reflecting respectively, ePCKT is related to what a teacher does in the classroom. The holistic nature of ePCK was investigated by using multiple data sources in real-life contexts. Specifically, pre-and post-observation interviews and lesson observations were used to elicit ePCK profiles and to provide triangulation. The grand rubric was customized for use both as an interview protocol and as an observational protocol for analyzing all of the three dimensions of ePCK around the analytical parameters of knowledge and skills related to curricular saliency, conceptual teaching strategies, and student understanding of science. Results revealed that chemistry teachers’ ePCK profiles are not uniform across planning, teaching, and reflecting phases, ePCK components, and evaluation criteria. Chemistry teachers perform highest in reflection concerning conceptual teaching strategies and lowest in teaching in terms of curricular saliency. Recommendations for science PCK research were shared.

Abstract Background Studying structural and functional morphology of small organisms such as monogenean, is difficult due to the lack of visualization in three dimensions. One possible way to resolve this visualization issue is to create digital 3D models which may aid researchers in studying morphology and function of the monogenean. However, the development of 3D models is a tedious procedure as one will have to repeat an entire complicated modelling process for every new target 3D shape using a comprehensive 3D modelling software. This study was designed to develop an alternative 3D modelling approach to build 3D models of monogenean anchors, which can be used to understand these morphological structures in three dimensions. This alternative 3D modelling approach is aimed to avoid repeating the tedious modelling procedure for every single target 3D model from scratch. Result An automated 3D modeling pipeline empowered by an Artificial Neural Network (ANN) was developed. This automated 3D modelling pipeline enables automated deformation of a generic 3D model of monogenean anchor into another target 3D anchor. The 3D modelling pipeline empowered by ANN has managed to automate the generation of the 8 target 3D models (representing 8 species: Dactylogyrus primaries, Pellucidhaptor merus, Dactylogyrus falcatus, Dactylogyrus vastator, Dactylogyrus pterocleidus, Dactylogyrus falciunguis, Chauhanellus auriculatum and Chauhanellus caelatus) of monogenean anchor from the respective 2D illustrations input without repeating the tedious modelling procedure. Conclusions Despite some constraints and limitation, the automated 3D modelling pipeline developed in this study has demonstrated a working idea of application of machine learning approach in a 3D modelling work. This study has not only developed an automated 3D modelling pipeline but also has demonstrated a cross-disciplinary research design that integrates machine learning into a specific domain of study such as 3D modelling of the biological structures.
