The micro-determinants of meso-level learning and innovation: evidence from a Chilean wine cluster   总被引：7，自引：0，他引：7  

Elisa Giuliani  Martin Bell 《Research Policy》2005,34(1):47-68

Most analyses of the relationship between spatial clustering and the technological learning of firms have emphasised the influence of the former on the latter, and have focused on intra-cluster learning as the driver of innovative performance. This paper reverses those perspectives. It examines the influence of individual firms’ absorptive capacities on both the functioning of the intra-cluster knowledge system and its interconnection with extra-cluster knowledge. It applies social network analysis to identify different cognitive roles played by cluster firms and the overall structure of the knowledge system of a wine cluster in Chile. The results show that knowledge is not diffused evenly ‘in the air’, but flows within a core group of firms characterised by advanced absorptive capacities. Firms’ different cognitive roles include some—as in the case of technological gatekeepers—that contribute actively to the acquisition, creation and diffusion of knowledge. Others remain cognitively isolated from the cluster, though in some cases strongly linked to extra-cluster knowledge. Possible implications for policy are noted.  相似文献   

SCiMet: Stable,sCalable and reliable Metric-based framework for quality assessment in collaborative content generation systems     

Mohammad Allahbakhsh  Haleh Amintoosi  Behshid Behkamal  Amin Beheshti  Elisa Bertino 《Journal of Informetrics》2021,15(2):101127

In collaborative content generation (CCG), such as publishing scientific articles, a group of contributors collaboratively generates artifacts available through a venue. The main concern in such systems is the quality. A remarkable range of research considers quality metrics partially when dealing with the quality of artifacts, contributors, and venues. However, such approaches have several drawbacks. One of the most notable ones is that they are not comprehensive in terms of the metrics to evaluate all entities, including artifacts, contributors, and venues. Also, they are vulnerable to potential attacks.In this paper, we propose a novel iterative definition in which the quality of artifacts, collaborators, and venues are defined interconnectedly. In our framework, the quality of an artifact is defined based on the quality of its contributors, venue, references, and citations. The quality of a contributor is defined based on the quality of his artifacts, collaborators, and the venues. Quality of a venue is defined based on both quality of artifacts and contributors. We propose a data model, formulations, and an algorithm for the proposed approach. We also compare the robustness of our approach against malicious manipulations with two well-known related approaches. The comparison results show the superiority of our method over other related approaches.  相似文献   

Teachers’ professional development through university–school partnerships: theoretical standpoints and evidence from two pilot studies in Chile     

Valeska Grau  Elisa Calcagni  David D. Preiss  Dominga Ortiz 《Cambridge Journal of Education》2017,47(1):19-36

This paper presents a teacher professional development programme, based on a university–schools partnership and a collective reflection model, addressing the needs of in-service teacher education in Chile. First, the main challenges faced by both teachers and teacher education in Chile are summarised. Then, the foundations of this model are presented. Finally, an illustration of the model is provided by presenting two pilot studies implemented in Chile. A qualitative analysis of interviews showed that the programme was successful in promoting teacher reflection, leading to reported changes in their practices. Finally, the advantages and the challenges arising from this study, and the educational possibilities of this model of professional development, are discussed.  相似文献   

Core Elements of the European (Higher) Education Policy: Market-Driven Restructuring or Impetus for Intercultural Rapprochement?     

Elisa Gavari Starkie 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2008,15(2):409-425

For many years there has been a debate about the existence or not, of a common European education policy. In this article I argue that there has been a real European education policy since the approval of the Maastricht Treaty, with a proper content and which offers many new possibilities to students. The core of this policy is the setting up of the European Higher Education Area, designed not only for attendance-based universities, but also for distance and virtual universities. However, the policies, expected to be in force by 2010, have not been without problems and a critique of the implications for European higher education institutes is offered following an outline of the development and evolution of the policies.  相似文献   

Near-peer teaching in an anatomy course with a low faculty-to-student ratio     

Durán CE  Bahena EN  Rodríguez Mde L  Baca GJ  Uresti AS  Elizondo-Omaña RE  López SG 《Anatomical sciences education》2012,5(3):171-176

Near-peer teaching is an educational format which utilizes tutors who are more advanced in a curriculum's content to supervise students' activities and to act as instructors in laboratory settings. This format is often used in anatomy laboratory courses. The goal of the present study is to describe the design and implementation of near-peer teaching in an anatomy course and to evaluate students' perceptions of the program. A total of 700 students were registered for this anatomy course which employed near-peer instructors. Of enrolled students, 558 (79.7%) agreed to participate in this study. In general, the practical section (e.g., the clinical hour, image-based anatomy session, and gross anatomy laboratory) of the course was viewed more favorably compared to the theory section (54.8%, n = 306), with dissection and prosection in the laboratory rated as the most valued experiences (34.9%, n = 195). Near-peer teaching is a viable option that satisfies the demands of modern curricula using small groups. This format stimulates learning within courses that have large numbers of students and low faculty-to-student ratios.  相似文献   

Mother and infant talk about mental states relates to desire language and emotion understanding   总被引：3，自引：0，他引：3  

Taumoepeau M  Ruffman T 《Child development》2006,77(2):465-481

This study assessed the relation between mother mental state language and child desire language and emotion understanding in 15-24-month-olds. At both time points, mothers described pictures to their infants and mother talk was coded for mental and nonmental state language. Children were administered 2 emotion understanding tasks and their mental and nonmental state vocabulary levels were obtained via parental report. The results demonstrated that mother use of desire language with 15-month-old children uniquely predicted a child's later mental state language and emotion task performance, even after accounting for potentially confounding variables. In addition, mothers' tendency to refer to the child's over others' desires was the more consistent correlate of mental state language and emotion understanding.  相似文献   

What makes a student feel vital? Links between teacher-student relatedness and teachers’ engaging messages     

Santana-Monagas  Elisa  Núñez  Juan L.  Loro  Juan F.  Moreno-Murcia  Juan A.  León  Jaime 《European Journal of Psychology of Education - EJPE》2023,38(3):1201-1226

Recent studies suggest that teacher messages can affect students’ well-being. Using a multilevel, variable, and person-centred approach, this study aimed to identify profiles of students according to their teachers’ use of engaging messages and analyse the relation among these profiles and teacher-student relatedness and students’ subjective vitality. A total of 1209 students participated in the study. At the student-level, profile analysis indicated the existence of four different profiles: the few messages profile, the autonomous motivational appeals profile, the loss-framed messages profile, and the gain-framed messages profile. At the teacher level, profile analysis indicated the existence of two profiles: the variant and the invariant profiles. Results showed that overall, at both levels of analysis, teachers’ engaging messages related with teacher-student relatedness (either positively or negatively) with clear differences among profiles. Moreover, also at both levels of analysis, teacher-student relatedness related with students’ subjective vitality. Main findings and implications for practice are discussed.
