Differences between web sessions according to the origin of their visits     

José Luis Ortega  Isidro Aguillo 《Journal of Informetrics》2010,4(3):331-337

The aim of this paper is to characterize the distribution of number of hits and spent time by web session. It also expects to find if there are significant differences between the length and the duration of a session with regard to the point of access–search engine, link or root. Web usage mining was used to analyse 17,174 web sessions that were identified from the webometrics.info web site. Results show that both distribution of length and duration follow an exponential decay. Significant differences between the different origins of the visits were also found, being the search engines’ users those who spent most time and did more clicks in their sessions. We conclude that a good SEO policy would be justified, because search engines are the principal intermediaries to this web site.  相似文献   

La formación permanente del profesorado de Lengua y Literatura: Modelos teóricos y actuación del asesor     

Luis González 《Cultura y Educación》2013,25(9):45-56

En este artículo se reflexiona sobre el papel del educador y del asesor de formación, al que se propugna más activo y centrado en la disciplina. Desde esa base se pasa a una segunda reflexión centrada en el papel de las ciencias del lenguaje en la educación en que se trata de establecer un puente entre los requerimientos del saber disciplinar y teórico sobre el lenguaje y los de las situaciones, textos y contextos reales de uso del lenguaje. Se trata una vez más de la vieja necesidad de articular en la ciencia y en la educación el rigor y la relevancia.  相似文献   

Informatica aplicada a la comprensión textual     

Luis Guerra  Juan Martín 《Cultura y Educación》2013,25(13):95-99

Uno de los inconvenientes de los programas didácticos que tratan de desarrollar en el alumno estrategias de comprensión lectora es que, dada la estructura grupal de la clase, deben aplicarse colectivamente cuando su propia naturaleza requeriría la aplicación individual. El ordenador puede conseguir aplicar a toda una clase los mismos modelos de comprensión, pero individualizadamente. En este artículo se expone un modelo experimental.  相似文献   

Relationships Among Measures as Empirical Evidence of Validity: Incorporating Multiple Indicators of Achievement and School Context     

Pete Goldschmidt  Jose Felipe Martinez  David Niemi  Eva L. Baker 《Educational Assessment》2013,18(3-4):239-266

In this article we examine empirical evidence on the criterion, predictive, transfer, and fairness aspects of validity of a large-scale language arts performance assessment, referred to as the Performance Assignment (PA). We use multilevel models to avoid biased inferences that might result from the naturally nested data. Specifically, we examine the relationships of the assessment with the Stanford Achievement Test, 9th Edition and the California High School Exit Examination. The results indicate that the measures are related, that students demonstrate a degree of transfer, and that the language arts PA is relatively more fair than comparison assessments. The results are robust to various model specifications and demonstrate that benefits do not accrue to all students equally.  相似文献   

Classroom Assessment Practices,Teacher Judgments,and Student Achievement in Mathematics: Evidence from the ECLS     

José Felipe Martínez  Brian Stecher  Hilda Borko 《Educational Assessment》2013,18(2):78-102

In this study we use data from the Early Childhood Longitudinal Survey third- and fifth-grade samples to investigate teacher judgments of student achievement, the extent to which they offer a similar picture of student mathematics achievement compared to standardized test scores, and whether classroom assessment practices moderate the relationship between the two measures. Results indicate that teacher ratings correlate strongly with standardized test scores; however, this relationship varies considerably across teachers, and this variation is associated with certain classroom assessment practices. Furthermore, the evidence suggests that teachers evaluate student performance not in absolute terms but relative to other students in the school and that they may adjust their grading for some students, perhaps with basis on perceived differences in need and/or ability.  相似文献

Determinants of cultural and popular celebration attendance: the case study of Seville Spring Fiestas     

María Luisa Palma  Luis Palma  Luis Fernando Aguado 《Journal of Cultural Economics》2013,37(1):87-107

The Spring Fiestas in Seville (Spain) (SFS) are the most important cultural events in the city each year. The present paper pursues two aims. The first is to characterize the SFS as a new prototype of a complex cultural good that expresses the link between the people and the place in which they live based on material and immaterial cultural heritage represented through popular celebrations. The second goal is to conduct an empirical analysis of the determinants that shape attendance intensity by estimating a zero-truncated count data model using a unique dataset of attendees at the SFS in 2009. Findings indicate that attendance is strongly associated with variables reflecting knowledge, institutional links, past experiences, and the perceived external benefits generated by the existence of the SFS. The article contributes to the literature by exploring participation in popular celebrations, a field of inquiry that to date is extremely limited in cultural economics.  相似文献   

Netflix: global hegemon or facilitator of frictionless digital trade?     

Luis Aguiar  Joel Waldfogel 《Journal of Cultural Economics》2018,42(3):419-445

Trade in cultural products has traditionally been constrained by a combination of law and technology. In Europe, digital sellers based in a given EU country are not always able to distribute across borders. In January 2016, US-based Netflix announced an expansion to 243 countries, accomplishing cross-border distribution through business strategy. Changes in law or technology that facilitate cross-national cultural trade have traditionally drawn the concern of observers worried about the cultural heritage—and products—of small markets. The expansion raises questions about what Netflix is doing. Is it a cultural hegemon, distributing US fare into 243 countries? Or it is a facilitator of free trade, making the products of even small countries more available outside their home markets (relative to traditional distribution)? And how does the curated model—which limits the number of movies the platform wants to distribute—affect Netflix’s function? To shed light on these questions, we develop a new measure of the global availability of a repertoire, the value-weighted geographic reach. Using this measure we find, first, that Netflix makes many of the works from a wide variety of countries available in many other countries. Second, we find that theatrical distribution strongly advantages US-origin fare. Third, the pattern of origin repertoire available through Netflix also favors the USA, although less overwhelmingly. Moreover, many countries are relatively advantaged by their Netflix availability patterns. Finally, we discuss some issues related to the Netflix platform, including horizontal competition with other platforms, vertical struggles with content providers (and its backward integration into production), and we speculate on possible challenges for regulators.  相似文献   

Sensemaking and social processes in digital government projects     

Luis Felipe Luna-Reyes  David F. Andersen  Laura J. Black  Theresa A. Pardo 《Government Information Quarterly》2021,38(2):101570

This research identifies main feedback dynamics associated with social processes necessary to make sense of ambiguous project goals, typical of large digital government projects. The study reports on findings from a case analysis using participatory approaches in system dynamics, based on a digital government project integrating information systems of New York's criminal justice agencies. Findings stress the importance of visuals in the sensemaking process that results from the interaction of technical and social outcomes produced through identifying and continuously re-interpreting main project issues and goals. Project analyses suggest that requisite elements of successfully managing this type of project include 1) facilitation that enables diversity of ideas, 2) shared visuals and re-presentations of participants' efforts to work on the issues, and 3) iterative social construction of objectives, progress, and valid processes for doing the work; each of these plays a role in three different feedback processes sustaining (or undermining) the group engagement needed to yield successful integrative work. The study contributes to the literature in digital government by introducing the lenses of people-centered project management processes, an emerging approach in project management, to underscore the role of social processes in technical projects.  相似文献   

Negotiating the cultural and economic outcomes of sport heritage attractions: the case of the National Baseball Hall of Fame     

Gregory Ramshaw  Sean Gammon  Felipe Tobar 《Journal of Sport Tourism》2019,23(2-3):79-95

ABSTRACT

Contemporary museums must balance their roles as commercial entities and repositories of various, and often dissonant, heritages and histories. Sports museums in particular often have clear commercial and nostalgic aims, particularly through tourist visitation, though the extent to which they represent more challenging narratives remains unclear. This paper examines how one of the most famous sports museums in the world, the National Baseball Hall of Fame (NBHF) in Cooperstown, New York, balances its dual role as tourist attraction and repository of baseball's sometimes checkered past. It was found that different sections of the museum provide greater or lesser degrees of engagement with more controversial issues, although the commercial outputs and appeal of the museum remains clear throughout. Utlimately, the NBHF demonstrates that balancing veneration and critique in collections can be commercially prosperous, and can provide a template for other sport and popular culture museums who may be wary of incorporating more challenging narratives in their exhibits. Furthermore, the symbiotic relationship between the Hall of Fame and the village of Cooperstown, particularly in creating and maintaining cultural and economic outputs, requires further exploration.  相似文献
