Most anatomists agree that cadaver dissection serves as a superior teaching tool in human anatomy education. However, attitudes toward body donation vary widely between different individuals. A questionnaire was developed to determine the attitudes toward body and organ donation among those who learn the most from cadavers: medical students, medical student teaching assistants, medical students involved in research, and anatomy professors. A cross‐sectional, prospective study was designed in which the questionnaire was distributed among first‐year human anatomy students before undertaking cadaver dissection at the beginning of the semester, and then again after a commemoration service at the end of the course. The questionnaire items included demographic data, as well as questions designed to characterize participants' attitudes regarding body/organ donation from strangers, family members, and whether participants would consider such practices with their own bodies. Out of a total of 517 students enrolled in the Human Anatomy course in the Medical School at the Universidad Autónoma de Nuevo León, Mexico during January to June 2016, 95% responded to the first (491) and second (490) surveys. Participants' opinions on their own organ donation was similar before and after exposure to cadaver dissection, with between 87% and 81% in favor of such practices, and only 3% against it, in both surveys. Participants' willingness to donate their own bodies, as well as those of family members, increased, while reluctance regarding such practices decreased by half (P < 0.0001 and P < 0.05). Professors had the highest rates of positive opinions regarding their own body donation (74.9%), with 18.8% undecided. Low opposition toward organ and body donation remains prevalent among both anatomists and physicians in training in Mexico.

A hybrid system of pedagogical pattern recommendations based on singular value decomposition and variable data attributes     

Carlos Cobos  Orlando Rodriguez  Jarvein Rivera  John Betancourt  Martha Mendoza  Elizabeth León  Enrique Herrera-Viedma 《Information processing & management》2013

To carry out effective teaching/learning processes, lecturers in a variety of educational institutions frequently need support. They therefore resort to advice from more experienced lecturers, to formal training processes such as specializations, master or doctoral degrees, or to self-training. High costs in time and money are invariably involved in the processes of formal training, while self-training and advice each bring their own specific risks (e.g. of following new trends that are not fully evaluated or the risk of applying techniques that are inappropriate in specific contexts).This paper presents a system that allows lecturers to define their best teaching strategies for use in the context of a specific class. The context is defined by: the specific characteristics of the subject being treated, the specific objectives that are expected to be achieved in the classroom session, the profile of the students on the course, the dominant characteristics of the teacher, and the classroom environment for each session, among others. The system presented is the Recommendation System of Pedagogical Patterns (RSPP). To construct the RSPP, an ontology representing the pedagogical patterns and their interaction with the fundamentals of the educational process was defined. A web information system was also defined to record information on courses, students, lecturers, etc.; an option based on a unified hybrid model (for content and collaborative filtering) of recommendations for pedagogical patterns was further added to the system. RSPP features a minable view, a tabular structure that summarizes and organizes the information registered in the rest of the system as well as facilitating the task of recommendation. The data recorded in the minable view is taken to a latent space, where noise is reduced and the essence of the information contained in the structure is distilled. This process makes use of Singular Value Decomposition (SVD), commonly used by information retrieval and recommendation systems. Satisfactory results both in the accuracy of the recommendations and in the use of the general application open the door for further research and expand the role of recommender systems in educational teacher support processes.  相似文献   

The Analytic Representation of Band-Pass Signals     

Enrique A. González-Velasco  Emilio Sanvicente 《Journal of The Franklin Institute》1980,310(2):135-142

The analytic representation of band-pass signals, which is extremely useful in information transmission and radar, is usually obtained by first introducing the Hilbert transform of a signal. We consider this procedure artificial, and propose here to follow the opposite path, which leads, in a natural way, to a motivated definition of the Hilbert transform. The key to this procedure is to show how, as a simple application of the Fourier integral, every band-pass signal can be expressed as the real part of a low frequency signal which modulates an exponential. Such a representation, called the analytic signal, is then used to define the Hilbert transform in a natural manner. Finally, we show that the term analytic signal is motivated by the fact that this signal is the restriction to the real axis of a function defined and analytic (holomorphic) in the upper half of the complex plane.  相似文献   

A comparison of extrinsic clustering evaluation metrics based on formal constraints     

Enrique Amigó  Julio Gonzalo  Javier Artiles  Felisa Verdejo 《Information Retrieval》2009,12(4):461-486

There is a wide set of evaluation metrics available to compare the quality of text clustering algorithms. In this article, we define a few intuitive formal constraints on such metrics which shed light on which aspects of the quality of a clustering are captured by different metric families. These formal constraints are validated in an experiment involving human assessments, and compared with other constraints proposed in the literature. Our analysis of a wide range of metrics shows that only BCubed satisfies all formal constraints. We also extend the analysis to the problem of overlapping clustering, where items can simultaneously belong to more than one cluster. As Bcubed cannot be directly applied to this task, we propose a modified version of Bcubed that avoids the problems found with other metrics.

Evaluation of a personalized digital library based on cognitive styles: Adaptivity vs. adaptability     

Enrique Frias-MartinezAuthor Vitae  Sherry Y. ChenXiaohui LiuAuthor Vitae 《International Journal of Information Management》2009

Personalization can be addressed by adaptability and adaptivity, which have different advantages and disadvantages. This study investigates how digital library (DL) users react to these two techniques. More specifically, we develop a personalized DL to suit the needs of different cognitive styles based on the findings of our previous work [Frias-Martinez, E., Chen, S. Y., & Liu, X. (2008) Investigation of behavior and perception of digital library users: A cognitive style perspective. International Journal of Information Management]. The personalized DL includes two versions: adaptive version and adaptable version. The results showed that users not only performed better in the adaptive version, but also they perceived more positively to the adaptive version. In addition, cognitive styles have great effects on users’ responses to adaptability and adaptivity. These results provide guidance for designers to select suitable techniques to develop personalized DLs.  相似文献   

Intellectual capital model for family firms     

Enrique Claver-Cortés  Hipólito Molina-Manchón  Patrocinio Zaragoza-Sáez 《知识管理研究与实践》2013,11(2):184-195

The intellectual capital-based view of the firm along with the literature about family firms serve as the basis for the present paper, which seeks to elaborate an intellectual capital model that can be applied to family firms. More precisely, our study identifies the main intangibles usually owned by family firms classifying those intangibles into human capital, structural capital and relational capital. In addition, the paper provides empirical evidence and gives examples of these intangibles through the analysis of external data from international family firms. The research question that we are trying to answer is: Which intangibles are owned by family firms for the mere fact of being family firms? Knowing the nature of the intangibles inherent to family firms can help improve their management, making the most of the intellectual capital owned by these firms when it comes to exploit their knowledge strengths.  相似文献

The effectiveness of a marketing virtual reality learning simulation: A quantitative survey with psychophysiological measures     

Billy Sung  Enrique Mergelsberg  Min Teah  Brandon D’Silva  Ian Phau 《British journal of educational technology : journal of the Council for Educational Technology》2021,52(1):196-213

Virtual reality (VR) technology has been shown to be a promising teaching method in STEM subjects. Extending these findings, the current study is the first to develop and examine the feasibility of using a VR simulation in marketing (ie, a non-STEM subject). Specifically, the levels of immersion and three learning outcomes (learning attitude, enjoyment and performance) were compared between the marketing students who learned the same content through a VR simulation prototype versus a traditional static video presentation. Learning enjoyment was measured using facial electromyography, which served as a more objective measures for the feeling of enjoyment. Compared to the video condition, the results showed that VR resulted in a higher experience of immersion, learning attitude and learning enjoyment. Furthermore, immersion was found to fully mediate the positive effects of the VR simulation on learning attitude, but not enjoyment. Surprisingly, students in the video condition performed better on the knowledge-based test than those in the VR condition. The current study suggests that the current prototype of the VR simulations should be used as supplementary resource to increase the learning attitude and enjoyment, but not as a main teaching material to enhance knowledge-based performance in the marketing discipline.  相似文献   

Ting,tang, tong: Emergent bilingual students investigating and constructing evidence-based explanations about sound production     

Enrique Suárez  Valerie Otero 《科学教学研究杂志》2024,61(1):137-169

There is a significant amount of research literature on the importance of identifying and building on students' experiences and ideas for making sense of the natural world, especially when engaging in science practices. Simultaneously, approaches to creating justice-oriented science education promote the need to focus on the diverse sense-making repertoires that students, especially those from historically marginalized communities, bring to science classrooms. However, when it comes to emergent bi/multilingual students, science education has favored narrow definitions of what ways of communicating are seen as productive for figuring out natural phenomena, privileging English-based academic vocabulary. In this article, we investigate the myriad conceptual and semiotic resources that third-grade emergent bilingual students developed and used when explaining sound production. Additionally, we explore how students investigated the sounds produced by a string instrument and unpacked the how and whys that give rise to the pitch of the sounds they heard. Our analyses indicate that: (1) students created mechanistic explanations that identified how changes to the salient physical features of strings affected the pitch of the sounds; (2) students created and laminated multiple semiotic resources when sharing their observations and explanations, particularly sound symbolisms; and (3) students navigated both semiotic convergence and divergence as they worked toward conceptual convergence. Based on our findings, we argue that justice-oriented science learning environments must become spaces where emergent bilingual students can build on all their conceptual, semiotic, and cultural resources, without being policed, as they engage science practices.  相似文献
