1、An integrated decision model for evaluating educational web sites from the fuzzy subjective and objective perspectives With advances in information and network technologies, lots of data have been digitized to reveal information for users by the construction of Web sites. Unfortunately, they ar

2、e both overloading and overlapping in Internet so that users cannot distinguish their quality. To address this issue in education, Hwang, Huang, and Tseng proposed a group decision system to evaluate the quality of educational Web sites by users and experts opinions. Their investigative source is so

3、lely stemmed from human intention, called the subjective perspective, to make judgments on the quality of Web sites. However, the nature of human beings in making decisions has a gap between intention and behavior. Asking people for eliciting thought is arduous to cause this gap. Human behavior, nam

4、ely the objective perspective, is the other essential source to obtain human thinking and real doings. For this reason, we can use data mining approaches to acquire the objective source. In this research, we propose an integrated decision model applied in evaluating educational Web sites from the fu

5、zzy subjective and objective perspectives. The former source is extracted by inquiring human opinion using a questionnaire, while the latter is gained automatically by a data mining technique, fuzzy clustering. An empirical study is carried out to validate the model capability.Psychologists' Att

6、itudes and Ethical Concerns Regarding the Use of Social Networking Web Sites  Most psychologists seek to control self-disclosures they make to patients, but the Internet's rapid development and widespread use over the past decade have introduced new problems for psychologists trying to

7、 avoid inappropriate disclosures. A total of 695 psychology graduate students and psychologists were surveyed about their current use of social networking Web sites (SNWs), opinions regarding regulation of online activities by the American Psychological Association (APA), and interactions in clinica

8、l work as a result of online activities. Established psychologists seldom use SNWs and may lack the experience to provide relevant supervisory guidance. No consensus about the need for APA guidelines emerged. Historically, APA has not issued guidelines in technological areas of rapid change. Thus, g

9、raduate training and continuing education should address the ethics of SNWs.Nursing students perception of a web-based intervention to support learning  Tailoring information to the needs of the learner is an important strategy in contemporary education settings. Web-based learning support

10、, informed by multimedia theory, comprising interactive quizzes, glossaries with audio, short narrated Power Point® presentations, animations and digitised video clips were introduced in a first year Bachelor of Nursing biological sciences subject at a university in metropolitan Sydney. All stu

11、dents enrolled in this unit were invited to obtain access to the site and the number of hits to the site was recorded using the student tracking facility available on WebCT, an online course delivery tool adopted widely by many educational institutions and used in this study. Eighty-five percent of

12、students enrolled in the subject accessed the learning support site. Students perception of the value of a learning support site was assessed using a web-based survey. The survey was completed by 123 participants, representing a response rate of 22%. Three themes emerged from the qualitative data co

13、ncerning nursing students perception of the web-based activities: enhances my learning, study at my own pace, and about the activities: what I really liked/disliked. Web-based interventions, supplementing a traditionally presented nursing science course were perceived by students to be beneficial in

14、 both learning and language development. Although students value interactive, multimedia learning they were not ready to completely abandon traditional modes of learning including face-to-face lectures. The findings of this study contribute to an understanding of how web-based resources can be best

15、used to support students learning in bioscience.WESONet: Applying semantic web technologies and collaborative tagging to multimedia web information systems  The publication of different media types, like images, audio and video in the World Wide Web is getting more importance each day. How

16、ever, searching and locating content in multimedia sites is challenging. In this paper, we propose a platform for the development of multimedia web information systems. Our approach is based on the combination between semantic web technologies and collaborative tagging. Producers can add meta-data t

17、o multimedia content associating it with different domain-specific ontologies. At the same time, users can tag the content in a collaborative way. The proposed system uses a search engine that combines both kinds of meta-data to locate the desired content. It will also provide browsing capabilities

18、through the ontology concepts and the developed tags.Cultural heritage interactive 3D models on the web: An approach using open source and free software  文化遺產(chǎn)繼承與文化建設(shè)、開放的文化資源共享網(wǎng)站建設(shè)Cultural heritage sites and artefacts get a significant added value from high-resolution 3D models. These model

19、s are increasingly available due to improvements in technology and to higher integration of survey techniques such as laser scanning and photogrammetry. In this paper we present a case study on the development of a web-based application for user access and interactive exploration of three-dimensiona

20、l models by providing integrated geometrical and non-geometrical information into an intuitive interface. The main feature of this interactive system is to provide the user with a completely new visit experience based on a free interactive exploration interface of the object (i.e., not constrained b

21、y any predefined pathway) and on the opportunity to get more detailed information on specific parts of interest. A parallel aim achieved was to use, in data processing and in the architecture, open source tools and free software, thus providing full transparency on adopted methodology and data proce

22、ssing methods, and a cost effective solution both for server and client. Furthermore, the aspect of data size has been considered using a segmentation and simplification scheme and server-side data management to keep transmission size to a minimum, thus improving access speed.HydroTest: Further deve

23、lopment of a web resource for the standardised assessment of hydrological models  水文及水利資源勘察與測繪評(píng)估網(wǎng)站高級(jí)開發(fā)模型Hydro Test is an open access web resource that was established in 2005. This site offers a wide range of statistical metrics for the testing and evaluation of hydrological modelling outp

24、uts. In providing computational support to the international scientific community the authors are aiming to ensure that reported studies are based on consistent and accurate evaluations expressed in terms of recognised global standards. This article reports a number of recent improvements to the res

25、ource. These developments include a fresh user interface, additional statistical measures of model performance, a graphing facility, and an option to perform the simultaneous analysis of multiple model outputs. Through continuing development of this open access resource the authors are attempting to

26、 share and promote: the latest analytical procedures; discussions on current thinking; and a dynamic hydrological modelling tool that is evolving in parallel with its associated application domain.Task-technology fit and user acceptance of online auction 政府公共科技信息與企業(yè)技術(shù)服務(wù)平臺(tái)建設(shè)技術(shù)與方法Word Wide Web in

27、telligent agent technology has provided researchers and practitioners, such as those involved in information technology, innovation, knowledge management, and technical collaboration with the ability to examine the design principles and performance characteristics of the various approaches to intell

28、igent agent technology, and to increase the cross fertilization of ideas on the development of autonomous agents and multi-agent systems among different domains. This study investigates the employment of intelligent agents in a web-based auction process, with particular reference to the appropriaten

29、ess of the agent software for the online auction task, consumers value perception of the agent, the effect of this consumer perception on their intention to use the tool, and a measure of consumer acceptance. In the initial case study, both consumers and web operators thought the use of software age

30、nts enhanced online auction efficiency and timeliness. The second phase of the investigation established that consumer familiarity with the agent functionality was positively associated with seven dimensions: online auction site's task, agent's technology, task-technology fit, perceived ease

31、 of use, perceived usefulness, perceived playfulness, intention to use tool, and negatively associated with perceived risk. Intelligent agents have the potential to release skilled operator time for the use of value-adding tasks in the planning and expansion of online auctions.The development of an

32、integrated technicalmethodical approach to visualise hydrological processes in an exemplary post-mining area in Central Germany  德國技術(shù)資料整合與共享網(wǎng)站建設(shè)The rapid development of software and hardware during the last decade caused a paradigm change in data processing. That is why, in geosciences, mo

33、nolithic GIS systems are increasingly complemented by web-based services and multimedia content, while geovisualisation is becoming more popular to visualise and analyse geoscientific processes. An increasing realism in geovisualisations tends to result in more complex geodata and metadata, requirin

34、g sophisticated solutions for efficient data management. This paper describes an integrated approach to geographic data processing and geovisualisation in an open, modular system. A former open-pit mining area in Central Germany characterised by a highly dynamic landscape and rapidly changing natura

35、l and anthropogenic processes has been chosen as an exemplary test site. Here, geovisualisation is used to depict the extreme changes in the landscape. The focus is on hydrological processes, which are highly complex and difficult to comprehend. The described approach will show how heterogeneous dat

37、he expectations towards learning might change, but also towards ICT competences and computer use. The purpose of this article is to find out whether freshmen, after 6 months at the university, changed their self-perception of ICT competences and computer use in comparison with their behaviour a

38、t secondary school, and what factors can explain the self-perception of ICT competences and computer use in secondary school, in the university and their possible change. Based on a panel research among 714 freshmen of a large university, this article answers the following questions: (1) What is the

39、 self-perception of ICT competences among freshmen and is there a change in this self-perception 6 months after entering the university? (2) How often and for what purpose do freshmen use a computer and is there a change in the frequency of the use of a computer? (3) What factors might influenc

40、e this attitude, behaviour, and possible change? In function of the basic components of Unified Theory of Acceptance and Use of Technology (Venkatesh, Morris, Davis, & Davis, 2003) hypotheses was developed and tested to answer these questions. Students who consider the computer to be a useful in

41、strument, have control over the computer, possess a certain level of Internet competence, and are at ease with computers are more likely to have the skills needed to maintain a computer, to develop a web site, and to use basic ICT skills. The predictors have little influence on Internet usage. The s

42、ame predictors contribute modestly to the explanation of the different frequencies of computer use, and a few of the predictors explain parts of change in ICT skills and frequency of computer use.大一新生的網(wǎng)絡(luò)學(xué)習(xí)環(huán)境建設(shè)。e-SELFQUAL: A scale for measuring online self-service quality The measurement of onli

43、ne self-service quality has become increasingly crucial as firms deliver an expanding array of services through their Web sites. Substantial research examines online services using salient scales primarily developed for personnel-orchestrated, face-to-face services; several recently developed scales

44、 that target online services focus on important information and/or system characteristics but do not consider e-retailers' fundamental roles holistically. The reported research synthesizes relevant previous research and proposes a conceptual framework to examine the quality of online self-servic

45、es in e-retailing. The proposed framework then guides a scale development effort that includes a series of pilot and validation studies. The resulting scale, e-SELFQUAL, provides a means for examining the relationships between online service quality and customer satisfaction, as well as loyalty in e

46、-retailing. This study has several important implications for research and business practice.Nursing students' perceptions of their resources toward the development of competencies in nursing informatics This article presents the findings of a doctoral study about the internal and external

47、resources required to develop nursing informatics competencies in student nurses. BackgroundColleges and universities are responsible for training nursing students, including in the area of nursing informatics. Even though nursing informatics is a specialty recognized by the American Nursing Associa

48、tion (2001), it has received limited attention in Quebec, Canada. MethodA total of 131 college-level nursing students were randomly surveyed with a mail questionnaire designed to describe their perceptions about their internal and external resources in nursing informatics. ResultsNursing students pe

49、rceive that their internal and external resources necessary to ensure “knowledge to act” in nursing informatics is moderately high. They said they lacked knowledge about using spreadsheet programs, presentation software, and courseware, about data security, and about how to analyze the quality of a

50、health-related Web site and search electronic scientific databases. ConclusionThese results show that, even if nursing students have access to a computer and the Internet at home and even if they feel competent using informatics in nursing, they still lack important resources for developing competencies in nursing informatics. We recommend that faculties and colleges focus on these elements.The development of work performance analysis system The purp
