Superficially free information services, such as social media platforms, search websites, and mobile apps. Earn revenue by collecting, aggregating, and monetizing user data. Users of these systems must give up control over this data in order to participate in the digital ecology. In a pilot study that queried the views of American university students, we explored the level of understanding young Americans...
The purpose of this study is to introduce a daily student practice identification algorithm that is capable of discovering if a quiz is good for the student as daily practice so the student can practice what he/she is not good enough and sharpen his or her skill and knowledge. The psychometric parameters of each question are studied in terms of item difficulty, item discrimination and distract or...
Ubiquitous connectivity has fostered an unprecedented wave of mobile computing and communication applications. As the number of mobile applications grows exponentially, a crucial issue is how users will monitor and manage their media 'flows' to optimal levels. This means having 'requisite' levels of information and communication, while avoiding states of hyper-connectivity. Our research is focused...
Flying developments of mobile technology bring new opportunities to teaching, people begin to exert themselves to integrate the predominance of mobile technology into curriculums. This paper first discusses the classification of mobile technology and its influences on education domain, then it analyses the learning surrounding of mobile device. Based on it, this paper expounds on the technology selection...
In this paper we present a on-field study for evaluating a crowd sourcing mobile social search application. With the help of the local crowd via social medias, this application assists foreign visitors in Japan by answering their image-based questions at hand in a timely fashion. We ran a controlled field experiment for 6 weeks with 55 participants. We found that the mobile crowd sourcing model demonstrated...
New media are changing the entire environment of IMC. With its unique advantages, NM extends the concepts, theories and methods of IMC to a brand new stage. In the background of fast development of new media, SMEs and large enterprises are once again standing on the same starting line.
Online and mobile communication through Web, email, chat and virtual worlds has raised perplexing questions about language change and unleashed a torrent of public discourse about the impact of emerging technologies on the linguistic and orthographic dimensions of computer-mediated communication (CMC), the shared rules for achieving linguistic competence in those media, and the long-term effects of...
New media technology students at university face many challenges from social to pedagogical when they start academic studies. One of the programs initial goals for these new students is to introduce them to some of the key social Web services that they will need to use for their schoolwork. The use of pervasive games to reach this specific purpose may help new students acclimate to these challenges...
The portable and immediate communication properties of mobile devices influence the learning processes in interacting with peers, accessing resources and transferring data. How to use communication technologies to improve mobile learning is an important topic in electronic education. Meanwhile, media selection can be a critical issue of supporting various reader devices and providing potential benefits...
In this paper we propose "SoTong" system for enhancing family relationship with relation oriented communication. In the relation oriented communications, we focus on the relationship by representation and promotion of relations together with awareness of other's situation for the connectedness and the coexistence. The system captures and analyzes communication channels among modern families...
Ensuring public security is an important issue for every government, and effective public security depends on the efficiency of criminal justice processes and procedures. The procedures of the criminal justice may be viewed as the upper-, middle-, and down-stream sections of a supply chain. Like their business counterparts, most law enforcement agencies have to deal with logistics, information flow,...
We consider data-streaming from an access point to multiple receivers, which is modeled as packet erasure channel. A simple network coding is shown to achieve larger rate region than without network coding, using minimal control information. The performance is characterized exactly using state transition graph. The scheme is then mapped to an information theoretic formulation for broadcast channel...
In this paper, we have designed and implemented the system architecture for extensible mobile instant messaging and presence service over the IMS. More specifically, we have implemented the SIP proxy servers for IMS P-CSCF and S-CSCF for the realization of extensible mobile instant messaging and presence service. The salient feature of the proposed system architecture is that the architecture is based...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
