This paper aims to demonstrate how the huge amount of Social Big Data available from tourists can nurture the value creation process for a Smart Tourism Destination. Applying a multiple-case study analysis, the paper explores a set of regional tourist experiences related to a Southern European region and destination, to derive patterns and opportunities of value creation generated by Big Data in tourism. Findings present and discuss evidence in terms of improving decision-making, creating marketing strategies with more personalized offerings, transparency and trust in dialogue with customers and stakeholders, and emergence of new business models. Finally, implications are presented for researchers and practitioners interested in the managerial exploitation of Big Data in the context of information-intensive industries and mainly in Tourism. 相似文献

差异的世界:大学排名的全球调查 总被引：3，自引：2，他引：3
本文研究了全球19个大学排行榜,描述了排行榜作为质量评价手段是如何运作的,详细讨论了现有排名系统使用的质量指标并归纳出在排名上存在的不同地域模式。本文发现,世界上的主要排行榜之间没有多少联系,它们采用差别很大的指标和权重来评估大学。但是,有一些大学,无论是用何种的指标和权重,都会居于排行榜的前列。本文还探讨了与目前流行的严格按分数高低排名的“排行榜”不同的做法,并得出了结论。 相似文献

We have developed an interactive case-based online network (ICON) that provides a new learning environment and integrates the student's thinking across the different concentration tracks of one of Harvard's interfaculty science initiatives. ICON takes advantage of this cross-disciplinary, undergraduate curriculum as a model system to bring a compelling, integrative focus to bear on reshaping how Harvard students learn neuroscience. ICON contains 9 learning modules specific to each case: Case, Working Papers, Blackboard, Neuroimaging, Research Programs and Trials, Decision Tree, Learning Objectives, Virtual Contact, and Brainstorm. Modules allow the student to get away from interpreting vast amounts of available information, move toward selecting useful information, recognize discriminating findings, and build a conceptual understanding of real and meaningful problems in neuroscience. The result is that ICON introduces a new landscape within the academic curriculum where the active participation of faculty and students effectively intersects and captures an immediate, integrative learning experience for the student. The benchmark of ICON is the time spent by students and faculty to create a user-defined learning network that engages faculty to participate in the students' learning and transforms the way the student thinks. 相似文献

The quality of content is a key attribute for assessing the globalquality of a museum application. Unfortunately, producing good content,especially in multimedia digital form, is expensive and time-consuming.One way to reduce the costs without sacrificing quality is to exploitthe concept of information reuse. The idea is to use (portions of) thesame multimedia material in different applications, possibly adapting itfor different contexts, for different categories of users, and fordifferent delivery channels (e.g., on-line and off-line). Informationreuse does not come free. To be effective, it requires a well-organizedenvironment in which information can be easily stored, inspected,retrieved, and adapted for different purposes. This paper describes theapproach adopted in the project ``The Virtual Museum of Italian ComputerScience History', funded by the Italian National Council of Research(CNR). In this project, all the digital material (documents, images,video interviews, etc.) is stored in a digital archive based on amultimedia database with a WWW front-end. The archive is designed forspecialists only: members of the editorial board of the project;researchers in the history of science; application developers (whoare looking for interesting content to include in their CD-ROMs or Websites). Each research group involved in the project extracted andadapted from the digital archive the multimedia material needed to builda different hypermedia application in two ``versions' – WWW andCD-ROM. These applications, both on-line and off-line, strongly reuse(portions of) the digital archive content, but organize and present itwith a totally different style, to address the needs of non-specialists(e.g., people who have some interest, or curiosity, in the history ofItalian computer science). 相似文献

Data from 492 Italian infants (8-18 months) were collected with the parental questionnaire MacArthur Bates Communicative Development Inventories to describe early actions and gestures (A-G) "vocabulary" and its relation with spoken vocabulary in both comprehension and production. A-G were more strongly correlated with word comprehension than word production. A clear developmental pattern for the different types of A-G was found. These findings are similar to those of different Western languages, indicating a common biological and cultural basis. The analysis of individual A-G and their relations with early words with a related meaning showed interesting similarities between the production of A-G with and without object manipulation and the comprehension and production of corresponding words. Results indicate that the transition from A-G to spoken language is mediated by word comprehension. 相似文献

The relative contributions of expertise in search skills and domain knowledge were examined when using the Internet to find information. Four conditions were compared: expert searchers/high domain knowledge; expert searchers/low domain knowledge; novice searchers/high domain knowledge; and novice searchers/low domain knowledge. Search outcomes and verbal protocols were analyzed. The combination of search expertise and high domain knowledge yielded the most efficient searches. Higher search expertise yielded access to sites rated more accurate and credible. High domain knowledge yielded sites rated more thorough. Verbal protocols depicted searching as a complex decision process. Findings have implications for instructional support. 相似文献

Within the theoretical framework of knowledge space theory, a probabilistic skill multimap model for assessing learning processes is proposed. The learning process of a student is modeled as a function of the student's knowledge and of an educational intervention on the attainment of specific skills required to solve problems in a knowledge domain. Model parameters are initial probabilities of the skills, effects of learning objects on gaining and losing the skills, and careless error and lucky guess probabilities of the problems. An empirical application shows that the model is effective in assessing knowledge and effectiveness of educational intervention at both classroom and student levels. Practical implications for teaching and learning are discussed. 相似文献

New product development nowadays makes heavy use of IT instruments such as virtual simulation tools. The main motivation for introducing virtual simulation tools in new product development is to speed up development and lower its cost. Virtual simulation tools, however, do much more. They introduce profound changes in the organization, including the nature of problem-solving, bearing the potential to increase new product development performance beyond cost and lead time reduction. Understanding these profound changes, we argue, holds the key to unlocking the potential of virtual simulation tools for improving new product development performance, including more innovative products. We support our argument with a case study from the European auto industry. 相似文献

This paper discusses a new algebraic model of electrical networks by which a deeper understanding is achieved of the interrelation existing between a system of independent cut sets and the corresponding system of independent “contours”, in the sense of orthogonal network theory (1).The new model allows, by a redefinition of f-cut sets, to give an interpretation in terms of linear graph theory to the inverse connection matrix A.sb, i.e. to the transformation matrix between voltages in the orthogonal and the primitive reference frames, for a general choice of independent contours.Furthermore, a directly algebraic derivation of the voltage transformation is presented, recalling the properties of dual vector spaces and without invoking the principle of invariance of the instantaneous power. 相似文献
