Social Computing: A Classification of Existing Paradigms
2012
In less than three decades, several paradigms of social computing have emerged. Among them, groupware, social software and mobile social software (MoSoSo) are the most widely known. Although all significant, it is challenging to recognize the function and unique features of each single paradigm. This situation represents an obstacle for a coherent development of social computing, a research domain that is highly fragmented and with relevant literature spread across several disciplines. In this paper, a classification of existing social computing paradigms is introduced as an initial effort to combine the lines of discourse concerning social computing.
Wiki as a collaborative writing tool in teacher education: Evaluation and suggestions for effective use
2014
The students did not collaborate much by revising each other's contributions to the wikis.The students did not use the discussion page to address critical reflections on collaboration.Factors influencing wiki-based collaborative writing in teacher education are discussed.Suggestions for effective use of wikis as collaborative writing tools are presented. Wiki technology provides new opportunities to foster collaborative writing in teacher education. To empirically evaluate the level of collaborative writing in a wiki-based environment, this article used three methods and their combination. The first method was the history function that records all students' actions, enabling to trace all ch…
Genome-Wide Association Study of Diabetic Kidney Disease Highlights Biology Involved in Glomerular Basement Membrane Collagen
2019
BACKGROUND: Although diabetic kidney disease demonstrates both familial clustering and single nucleotide polymorphism heritability, the specific genetic factors influencing risk remain largely unknown.METHODS: To identify genetic variants predisposing to diabetic kidney disease, we performed genome-wide association study (GWAS) analyses. Through collaboration with the Diabetes Nephropathy Collaborative Research Initiative, we assembled a large collection of type 1 diabetes cohorts with harmonized diabetic kidney disease phenotypes. We used a spectrum of ten diabetic kidney disease definitions based on albuminuria and renal function.RESULTS: Our GWAS meta-analysis included association result…
The dynamics of online news discussions: effects of news articles and reader comments on users’ involvement, willingness to participate, and the civi…
2017
ABSTRACTThis study investigates when and why news website visitors write civil or uncivil comments in response to news articles or related user comments. In an experiment, we manipulated the news value of news articles and the presence of ‘deliberative’ or ‘detrimental’ elements of comments to compare their impact on participants’ involvement, willingness to comment, and the comments they posted. News factors and comment characteristics increased participants’ willingness to comment via cognitive and affective involvement. Cognitive involvement made it less likely and affective involvement more likely that participants wrote uncivil comments. Additionally, involvement with previous comments…
Predictive and Evolutive Cross-Referencing for Web Textual Sources
2017
International audience; One of the main challenges in the domain of competitive intelligence is to harness important volumes of information from the web, and extract the most valuable pieces of information. As the amount of information available on the web grows rapidly and is very heterogeneous, this process becomes overwhelming for experts. To leverage this challenge, this paper presents a vision for a novel process that performs cross-referencing at web scale. This process uses a focused crawler and a semantic-based classifier to cross-reference textual items without expert intervention, based on Big Data and Semantic Web technologies. The system is described thoroughly, and interests of…
Location of navigation menus in websites: an experimental study with Arabic users
2015
Published online: 31 October 2015 While Arabic users represent by far the fastest growing language population on the Internet, research about how the peculiarities of Arabic language may shape users’ web interactions is still scarce. The preferences of Arabic users for menu location in websites have been studied. Two competing arguments have been proposed regarding the best location of menus in websites: conventional design (navigation menu should be placed on that side where users expect it based on previous experience) and reading direction (navigation menu should be placed on that side where readers are used to start off reading, so that the navigation menu is likely to be attended first…
Information Integration Platform for Patient-Centric Healthcare Services: Design, Prototype and Dependability Aspects
2014
Published version of an article in the journal: Future Internet. Also available from the publisher at: http://dx.doi.org/10.3390/fi6010126 Open Access Technology innovations have pushed today’s healthcare sector to an unprecedented new level. Various portable and wearable medical and fitness devices are being sold in the consumer market to provide the self-empowerment of a healthier lifestyle to society. Many vendors provide additional cloud-based services for devices they manufacture, enabling the users to visualize, store and share the gathered information through the Internet. However, most of these services are integrated with the devices in a closed “silo” manner, where the devices can…
A wiki task for first-year university students : the effect of scripting students' collaboration
2015
Abstract This study investigates the effect of a collaboration script - i.e. a set of instructions to improve collaboration between learning partners - for a wiki task. Participants were first-year university students in Educational Sciences ( N = 186) collaborating in groups of five during a three-week period to create a wiki on peer assessment in education. Two conditions were contrasted: a scripted and a non-scripted condition. The effect of scripting was measured in four ways (questionnaires, log-file analyses, group product scores, and individual pre–post-test scores). Results show significant positive effects of scripting with respect to the collaborative group processes and students…
Doppler Shift Characterization of Wideband Mobile Radio Channels
2019
The prevailing approach for characterizing the Doppler shift (DS) of mobile radio channels assumes the transmission of an unmodulated carrier. This consideration is valid for the analysis of narrowband channels, but its pertinence is questionable in regards to the modeling of wideband channels. In this correspondence, we redefine the DS from a time-frequency analysis perspective that does not depend on the aforementioned assumption. We systematically demonstrate that the DS can be characterized by the instantaneous frequency of the channel transfer function. This generic definition makes evident a fundamental aspect of the DS that is seldom acknowledged, namely, the DS is a frequency-varyin…
Creating a semantically-enhanced cloud services environment through ontology evolution
2014
Currently, the availability of Web resources has grown enormously to the point that whatever a user needs at a given moment can potentially be found on the Internet. These resources are not limited to data items anymore, functionality delivered through some sort of service architectural model is also offered on the Internet. In the last few years, cloud computing has emerged as one of the most popular computing models to provide services over the Internet. However, as the number of available cloud services increases, the problem of service discovery and selection arises. Experience indicates that semantic technologies can provide the basis for enhanced and more precise search processes. In …
