Although mainstream preschool programs have been in existence since the 1970s, little is known about the ways in which typical children attempt to understand what it means for a peer to have a disability. In this study, 4-year-old children without disabilities who were enrolled in a mainstream preschool class explained their peers' disabilities by referring to concepts of immaturity, accident, or adaptive equipment to account for the behavioral differences that they observed. The implications of these cognitions for children's developing attitudes and behaviors toward peers with disabilities are discussed.  相似文献   

Toward a Pedagogy of Transformation     

Joseph P. Keating  Rosario Diaz‐Greenberg  Mark Baldwin 《Teaching Education》2013,24(2):155-162

An on-going challenge in teacher education programs is how best to support new teachers in connecting their university coursework with their professional identity development and pedagogical practice in the schools. The reading and writing of case studies is one promising strategy teacher educators have explored as a means of assisting teachers in developing and cultivating a self-reflective, theory and practice reflexive, style of learning in the teacher education classroom and beyond. In the present paper, I present a case study of my own journey as a developmental and educational psychologist responsible for co-teaching a secondary teacher education course called "Adolescent Development for Teachers", in which having student-teachers research and write-up a case study of a single adolescent became the focus of the course and our pedagogy. I describe events that brought about the use of the case study in the course, the influence the use of the case study had on myself as an instructor as well as the students, and what students say are the educational benefits and difficulties of completing the adolescent case study. Implications for infusing a developmental focus into teacher education programs are discussed.  相似文献   

Agents control in intelligent learning systems: The case of reactive characteristics     

Ana Lilia Laureano-Cruces  Javier Ramírez-Rodríguez  Fernando de Arriaga  Rafael Escarela-Pérez 《Interactive Learning Environments》2013,21(2):95-118

Intelligent learning systems (ILSs) have evolved in the last few years basically because of influences received from multi-agent architectures (MAs). Conflict resolution among agents has been a very important problem for multi-agent systems, with specific features in the case of ILSs. The literature shows that ILSs with cognitive or pedagogical agents are prone to arbitration methods, where as ILSs with reactive agents are much in favor of control mechanisms. For these kind of systems, different control types are proposed based on the different stimuli that these agents will receive. These stimuli are aspects to be evaluated during the teaching/learning process such as: (1) error analysis, (2) learning styles, (3) analogies, (4) social aspects, etc.

The paper reviews several ILSs, related to our work; different control mechanisms are proposed to solve the agents' intervention conflicts. Finally, the use of several mechanisms is exemplified by the results of a specific ILS.  相似文献   

Granite desalination using electromigration. Influence of type of granite and saline contaminant     

Jorge Feijoo  Xosé Ramón Nóvoa  Teresa Rivas  María Jesús Mosquera  Javier Taboada  Cristina Montojo  Fernando Carrera 《Journal of Cultural Heritage》2013,14(5):365-376

We describe the results of electromigration desalination of two soluble salt-contaminated Galician granites. The efficacy of electromigration, which had not been previously applied to granite, was assessed for two types of granite contaminated with a 20% NaCl solution and seawater. Desalination effectiveness was evaluated as follows: (1) analysis of anode and cathode ion content during testing; (2) analysis of ions at different distances from the electrodes after testing; (3) pH assessment of the stone surfaces; and (4) evaluation of colour changes. Results were very satisfactory; by the end of testing, chloride was reduced by almost 100% in both the NaCl and seawater contaminated samples. Sulfate reduction was also significant, despite this ion's lower mobility. The granite pH values remained close to neutral and colour changes were minimal. The difference in effectiveness of the process for the two types of stone was associated with their dissimilar pore structure.  相似文献   

Less than expected—The minor role of foreign firms in upgrading domestic suppliers—The case of Vietnam     

Thi Xuan Thu Nguyen  Javier Revilla Diez 《Research Policy》2019,48(6):1573-1585

Vietnam is an important case for studying the impact of foreign firms’ backward linkages on local firms’ productivity. As an emerging economy Vietnam became the second most popular FDI destination after China in Pacific Asia since 2014. Our empirical analysis for Vietnam as a whole demonstrates a significant difference in the productivity growth between domestic suppliers who have a direct linkage with foreign firms and non-suppliers. This is also true for the Southeast Region (SE) with Ho-Chi-Minh City as economic center. However, in the Red River Delta (RRD), that difference is not statistically significant. Based on in-depth interviews with domestic suppliers, we reveal that in the RRD, effects of foreign firms on the productivity upgrading of domestic suppliers are indirect and limited while internal factors like absorptive capacity are more important for the productivity growth. These regional differences can be traced back to different regional specializations which still persist from the pre-reform era.  相似文献   

Social network data to alleviate cold-start in recommender system: A systematic review     

Lesly Alejandra Gonzalez Camacho  Solange Nice Alves-Souza 《Information processing & management》2018,54(4):529-544

Recommender Systems are currently highly relevant for helping users deal with the information overload they suffer from the large volume of data on the web, and automatically suggest the most appropriate items that meet users needs. However, in cases in which a user is new to Recommender System, the system cannot recommend items that are relevant to her/him because of lack of previous information about the user and/or the user-item rating history that helps to determine the users preferences. This problem is known as cold-start, which remains open because it does not have a final solution. Social networks have been employed as a good source of information to determine users preferences to mitigate the cold-start problem. This paper presents the results of a Systematic Literature Review on Collaborative Filtering-based Recommender System that uses social network data to mitigate the cold-start problem. This Systematic Literature Review compiled the papers published between 2011–2017, to select the most recent studies in the area. Each selected paper was evaluated and classified according to the depth which social networks used to mitigate the cold-start problem. The final results show that there are several publications that use the information of the social networks within the Recommender System; however, few research papers currently use this data to mitigate the cold-start problem.  相似文献

Reference power values for the jump squat exercise in elite athletes: A multicenter study     

Pedro L. Valenzuela  Michael McGuigan  Guillermo Sánchez-Martínez  Elaia Torrontegi  Javier Vázquez-Carrión  Zigor Montalvo 《Journal of sports sciences》2020,38(19):2273-2278

ABSTRACT

The present study aimed to provide reference values for lower-limb muscle power assessed during the incremental jump squat (JS) test in elite athletes (i.e., professional athletes competing at international level). We pooled data from all JS tests performed by elite athletes of different sports in two high-performance centres between 2015 and 2019, and computed reference values (i.e., terciles) for mean power (MP), mean propulsive power (MPP), and peak power (PP). Reference values were obtained from 684 elite athletes (458 male and 226 female) of 16 different sports (boxing, judo, karate, fencing, taekwondo, wrestling, basketball, soccer, futsal, handball, rugby union, badminton, tennis, long distance running, triathlon, and sprinting). Significant differences (p < 0.001) were found between male and female athletes for MP (7.47 ± 1.93 and 6.15 ± 1.68 W·Kg^?1, respectively), MPP (10.50 ± 2.75 and 8.63 ± 2.43 W·Kg^?1), and PP (23.64 ± 6.12 and 19.35 ± 5.49 W·Kg^?1). However, the velocity at which these power measures was attained seemed to be independent of sex (~0.95, 1.00 and 2.00 m·s^?1 for mean, mean propulsive, and peak velocity, respectively) and homogeneous across different sport disciplines (coefficient of variation <10%). These data can be used to classify athletes’ power capabilities, and the optimum velocity ranges provided here could be useful for training purposes.  相似文献

Investigating Supervisory Relationships and Therapeutic Alliances Using Structural Equation Modeling     

Mary Kristina DePue  Glenn W. Lambie  Ren Liu  Jessica Gonzalez 《Counselor Education & Supervision》2016,55(4):263-277

The authors used structural equation modeling to examine the contribution of supervisees' supervisory relationship levels to therapeutic alliance (TA) scores with their clients in practicum. Results showed that supervisory relationship scores positively contributed to the TA. Client and counselor ratings of the TA also differed.  相似文献
