A case study for impelling university research productivity and impact through collaboration is presented. Scientometric results support the hypothesis that a knowledge management model increased research collaboration and thereby boosted a university’s number of publications and citations. Results come from fifteen years of data at a Mexican university with 2400 researchers who produced 24,000 works in fifteen research disciplines. These data are treated with social network visualizations and algorithms to identify patterns of collaboration and clustering, as well as with normalizations to make disciplines comparable and to verify increasing citation impact. The knowledge management model implemented in the study may be a cost-effective way for universities to intensify collaboration and improve research performance. 相似文献

The most common way of designing databases is by means of a conceptual model, such as E/R, without taking into account other views of the system. New object-oriented design languages, such as UML (Unified Modelling Language), allow the whole system, including the database schema, to be modelled in a uniform way. Moreover, as UML is an extendable language, it allows for any necessary introduction of new stereotypes for specific applications. Proposals exist to extend UML with stereotypes for database design but, unfortunately, they are focused on relational databases. However, new applications require complex objects to be represented in complex relationships, object-relational databases being more appropriate for these requirements. The framework of this paper is an Object-Relational Database Design Methodology, which defines new UML stereotypes for Object-Relational Database Design and proposes some guidelines to translate a UML conceptual schema into an object-relational schema. The guidelines are based on the SQL: 1999 object-relational model and on Oracle8i as a product example.Received: 22 January 2002, Revised: 10 June 2002, This paper is a revised and extended version of Extending UML for Object-Relational Database Design, presented in the UML2001 conference [17]. 相似文献

Leadership and leader behavior are important topics for any professional discipline. However, these issues have been neglected
throughout the entire short history of counseling. Despite the fact that many counselors attain various leadership positions,
little attention has been paid to training for leadership. While much has been written about the various roles of counselors,
leadership and the behavior of leaders are rarely the focus. It is our contention that counselors, because of their unique
training, can be effective leaders in a wide variety of settings. This article argues for a greater emphasis by counselor
education on the role of counselor as leader. 相似文献

This randomized, controlled study examined the effectiveness of Child Parent Relationship Therapy (CPRT) in school settings with 48 low‐income Latino immigrant parents whose children were identified with behavioral concerns. Results from a 2 (group) × 2 (measures) split plot analysis of variance indicated that parents who participated in 11 weeks of CPRT reported statistically significant decreases (p < .001) in child behavior problems and parent–child relationship stress. Large treatment effects were demonstrated for all dependent variables. Clinical significance of findings and cultural considerations are discussed. © 2010 Wiley Periodicals, Inc. 相似文献

ResumenEste trabajo constituye una aplicación práctica de la teoría de Piaget y sus colaboradores al estudio del conocimiento espacial en los niños ciegos. Comienza con una breve introducción teórica donde se revisan las investigaciones sobre conocimiento espacial realizadas con personas invidentes. Después se describe el trabajo experimental que consiste en la utilización de tres de las pruebas piagetianas más conocidas («Coordinación de perspectivas», «Colocación de un muñeco en un modelo de aldea» y «Medición espontánea») con sujetos ciegos, videntes con visión funcional y videntes con los ojos tapados, de edades comprendidas entre 7 y 15 años. Los resultados ponen de manifiesto la capacidad de los niños ciegos de nacimiento para tener un conocimiento fundamental del espacio, si bien con un considerable retraso respecto a los videntes. Se concluye destacando las peculiaridades de la curva evolutiva de los invidentes, así como las perspectivas para futuras investigaciones sobre psicologia cognitiva de la ceguera. 相似文献

Three experiments explored the link between reward shifts and latent inhibition (LI). Using consummatory procedures, rewards were either downshifted from 32% to 4% sucrose (Experiments 1–2), or upshifted from 4% to 32% sucrose (Experiment 3). In both cases, appropriate unshifted controls were also included. LI was implemented in terms of fear conditioning involving a single tone-shock pairing after extensive tone-only preexposure. Nonpreexposed controls were also included. Experiment 1 demonstrated a typical LI effect (i.e., disruption of fear conditioning after preexposure to the tone) in animals previously exposed only to 4% sucrose. However, the LI effect was eliminated by preexposure to a 32%-to-4% sucrose devaluation. Experiment 2 replicated this effect when the LI protocol was administered immediately after the reward devaluation event. However, LI was restored when preexposure was administered after a 60-min retention interval. Finally, Experiment 3 showed that a reward upshift did not affect LI. These results point to a significant role of negative emotion related to reward devaluation in the enhancement of stimulus processing despite extensive nonreinforced preexposure experience. 相似文献

ResumenEl presente artículo tiene como objetivo analizar los procesos de codificación y almacenamiento en tareas que implican el sistema de la MCP. Con este fin, hemos utilizado material verbal y hemos manipulado el grado de similitud táctil y fonética de los estímulos para estudiar su efecto en la retención a corto plazo. Los resultados de los dos experimentos indican, por un lado, que los ciegos se sirven de formatos de naturaleza diferente (táctil-fonémica) para mantener la información a corto plazo y, por otro lado, que incrementan su capacidad de almacenamiento con la edad. 相似文献
