Full textAbstract:
Designing innovative communications services that scale to facilitate potential new usage patterns can pose significant challenges. This is particularly the case if these services are to be delivered over existing protocols and interoperate with legacy services. This work explores design choices for such a service: large scale message delivery to existing Instant Messaging users. In particular the authors explore message throughput, accuracy and server load for several alternative implementation strategies. These strategies focus on approaches to concurrency, with best practice in current and emerging techniques thoroughly benchmarked. Specifically, a conventional Java Executor approach is compared with a functional approach realised through Scala and its Actors framework. These could be termed “blocking I/O” technology. A third approach has also been measured - a “non-blocking I/O” based on an alternative to Java Virtual Machine approaches - employing Node.js and Javascript. We believe that some of the results are startling.

The last decade has seen a significant popularity of instant messaging and its main usage is for recreational purposes. However, instant messaging can also be utilized in the workplace and by utilizing such tools more efficiency of workplace communication can be achieved. For this purpose, in this paper we conduct research on mobile instant messaging in the workplace. Mobile Internet services based communication is chosen because mobile communication is playing an important role in today's communication system. First, the system architecture of a mobile instant messaging is presented. Some main functionality, such as message exchange and file transmission, are elaborated. Then, based on this architecture, an android-based messaging client and a Linux-based server are developed. Finally, the instant messaging software is tested in a real mobile communication network and test results show that the software works well. As mobile Internet services become increasingly important, the instant messaging tool developed in this paper will be utilized in the workplace as a communication means and will improve work efficiency greatly in the future.

Purpose – The purpose of this paper is to examine the continued usage of mobile instant messaging (IM) from the perspectives of both motivators and inhibitors. Design/methodology/approach – To cast light on the motivators and inhibitors of continuance intention (CI) to use mobile IM, 268 responses from Chinese mobile IM users were collected via an online survey. Findings – The results suggest that perceived system quality, procedural switching cost and relational switching cost (RSC) positively affect resistance to change (RTC), while perceived user base, perceived quality of communication, RSC and RTC positively affect the CI. Among them, RTC has the greatest effect on the CI, and RSC has the largest effect on RTC. Originality/value – Extant research has mainly focussed on the motivators behind the continued usage of mobile services. However, the inhibitors, such as switching cost and RTC, have been less considered in the research on the continued usage of mobile services. Also, only a little research has examined the components of switching costs and how they affect the intention to continue using mobile services. The current study attempts to fill these research gaps.

Full textAbstract:
Smartphones have become an essential part of our everyday life. Use of mobile instant messaging applications (e.g., WhatsApp, Messenger, iMessage, Kik, Viber, GroupMe, Telegram, Send, Line, and Snapchat) rather than messaging services from cellular service providers have become very popular among users, far outpacing the use of more traditional text messaging. Initial research revealed that the global usage of these modes of communication far outnumber standard text messaging. These instant messaging apps allow users to perform the same function as traditional communication tools (text, voice call, audio message, video call from phone carrier’s number). Additionally, they offer other capabilities such as creating group chats, and sharing photos/videos – in many cases without the need of using data plan coverage from phone carriers. Although instant messaging applications have become very popular, their use for communication may not be considered as often as traditional voice and text message phone records when assessing accident causation due to potential driver distraction from phone usage. The purpose of this paper is to highlight the prevalence of instant messaging applications, the need to consider the usage of instant messaging applications when assessing potential driver and pedestrian distractions due to smartphone usage, and some initial tools for gathering data on usage of some of the applications.

Telecommunication networks and the Internet are growing together. Peer-to-Peer (P2P) services which are originally offered by network providers, like telephony and messaging, are provided through VoIP and Instant Messaging (IM) by Internet service providers, too. The IP Multimedia Subsystem (IMS) is the answer of the telecommunication industry to this trend and aims at providing Internet P2P and multimedia services controlled by the network operators. The IMS provides mobility and session management as well as message routing, security, and billing.

Full textAbstract:
Instant messaging services usually integrate a notification system on their users’ devices, as phone calls and short message service (SMS) systems do. Telegram is – as far as we are aware – the only popular instant messaging service that uses open source code. Telegram also provides APIs for their users, enabling the development of a bot system that allows instant messaging application to access information. Here, we study the potential use of Telegram bot as a user interface to a paperless office (PLO) system developed in our institution. We found that Telegram bot improves communication among the users; however, as the amount of messages increased, the server becomes overloaded. This limitation suggests that future works need to be directed to improving the efficiency of the bot

Objective – To examine provider pessimism by comparing user and provider perception of the same instant messaging reference transaction.
Design – Instant messaging users and providers completed post-reference transaction surveys which were analyzed using the pair perception comparison method.
Setting – A large research university in the United States.
Subjects – Two hundred undergraduate journalism students (users of the instant messaging service) and 51 Master of Library Science (MLS) students enrolled in a reference services class (providers of the instant messaging service).
Methods – The authors created a research help webpage from which users could access the instant messaging service. Prior to service availability, providers received reference instruction and demonstrated reference aptitude through in-class activities. The authors briefed providers on the project and provided a wiki containing resources they might need during reference transactions. Providers worked in two-hour shifts, and two providers were available during each shift. The service was available for one week while potential users completed a journalism assignment. The authors asked both users and providers of the service to complete an online survey at the conclusion of the reference transaction. Users and providers completed different surveys, but both types included the following four elements: questions to aid in matching a user to a provider; questions about satisfaction with the service based on guidelines put forth by the Reference and User Services Association (RUSA); open-ended questions about the reference transaction; and questions regarding demographics, prior reference service usage, and knowledge of instant messaging. There were 55 valid reference transactions, and from those, the authors matched 26 pairs of user and provider surveys. The authors analyzed paired surveys to (a) compare the user’s perception of the reference transaction with the provider’s guess about the user’s perception and (b) compare the provider’s self-perception of the reference transaction with the provider’s guess about the user’s perception. The authors introduced the pair perception comparison method for the analysis using two-tailed paired t-tests and Wilcoxon signed-rank tests.
Main Results – Analysis of background information showed that users were younger on average than providers and used instant messaging more frequently. Even so, most users and providers felt comfortable with instant messaging.
When providers were asked to guess how satisfied overall they thought the user was with the reference transaction, they reported on average that the user was less satisfied than the user actually was. These results were statistically significant. The authors found no significant difference between the providers’ overall satisfaction with the service they provided and their guesses about the users’ overall satisfaction.
The authors also analyzed the matched pairs on 14 specific aspects of satisfaction gathered from surveys. When comparing the users’ satisfaction with the service they received and the providers’ guesses about the users’ satisfaction, the providers underestimated the users’ satisfaction on average for all 14 dimensions. The authors found statistically significant differences with regard to 7 of the 14 dimensions: tempo, ease of use, friendliness, understanding, accuracy, follow up, and spelling. When comparing the providers’ satisfaction with a given reference transaction and their guesses about the users’ satisfaction with the same reference transaction, the authors found significant differences for 3 of the 14 dimensions: interest, resource type, and accuracy.
Conclusion – This study has shown for instant messaging reference what other studies have shown for face-to-face reference—that provider pessimism exists. Whatever the environment, providers of reference tend to judge themselves more harshly than the people they are helping judge them. Based on a review of the literature, the authors further note that both expert and novice reference providers experience such pessimism. The authors are hopeful that providers will view these results as evidence of their own competence during instant messaging reference transactions.
The results of this study provide valuable information for training instant messaging providers. For example, the fact that providers thought users were less satisfied with the tempo of the reference transaction than they really were suggested to the authors that instant messaging providers need not be so concerned about giving a quick answer. An accurate answer is more desirable. In the same vein, providers thought that users were more concerned with spelling than they really were. Both of these cases, and others gleaned from the results, provide insight into what aspects of the reference transaction providers should spend their time and effort on.
Finally, the authors introduced the pair perception comparison method to compare feedback from matched pairs on individual reference transactions, a methodology not used in any earlier studies. They deemed this method to be an effective way to uncover biases and false assumptions.

Mobile technologies and platforms that facilitate communication across different languages are increasingly relevant in a world characterised by the global flows of diverse populations and disparate digital environments. This qualitative study explores communication between native and non-native speakers of Korean, mediated through mobile instant messaging in the sophisticated digital environment of South Korea. This article reports on two studies that examined the experiences of English-speaking language instructors (Study 1) and international students (Study 2) in a private university situated in South Korea during 2012 and 2015, respectively. This is done by focusing on face-to-face and screen-to-screen communication, and the co-dependencies arising between language instructors and international students. Between 2012 and 2015, large upgrades in the local digital environment saw the emergence of ubiquitous low cost or free high-speed Wi-Fi coverage and a near universal national adoption of a local mobile instant messaging service. The participants in Study 2 were widely found to be digitally literate and demonstrated an acuity with mobile instant messaging. They developed creative solutions for communication and language learning by blending sociolinguistic and linguistic competencies within mobile instant messaging chat rooms. This article highlights the changes that have occurred between 2012 and 2015 and demonstrates the need for further research into how mobile instant messaging services support communication between people from different language and culture backgrounds, particularly for people without access to formal language instruction.

Mobile Instant Messaging (MIM) or Instant Messaging (IM) via various web-based applications like WeChat, Viber, WhatsApp (WA) and Snapchat have gained much attention. It allows mobile phone users to access instant messaging services right from their smartphones. Despite various general publications indicating the advantages of mobile business, ranging from the start-up cost, flexibility, mobility up to inventory, the MIM’s application via mobile businesses are still scarce. The aim of this study was to examine the realm of MIM usage as a platform for mobile business among undergraduates in Malaysia by examining the uses of MIM for mobile business and to identify the perceived advantages of MIM as a platform for mobile business. An online questionnaire was designed and randomly distributed among identified undergraduates who have actively engaged in mobile business. The results show that MIM is frequently used to advertise and sell products most needed by undergraduates. Among the perceived advantages of MIM as a platform for mobile business is its cost effectiveness. In addition, undergraduates can easily and conveniently start-up mobile businesses and generate income simply via a mobile device and a mobile number as it is indeed preferable for reaching a general audience.

Abstract There has been a drive towards increased digitalisation in healthcare. The aim was to provide a snapshot of current apps, instant messaging, and smartphone photography use in paediatric emergency care. A web-based self-report questionnaire was performed. Individual physicians working in paediatric emergency care recorded their personal practice. One hundred ninety-eight medical doctors completed the survey. Eight percent of respondents had access to institutional mobile devices to run medical apps. Eighty-six percent of respondents used medical apps on their personal mobile device, with 78% using Apple iOS devices. Forty-seven percent of respondents used formulary apps daily. Forty-nine percent of respondents had between 1–5 medical apps on their personal mobile device. Respondents who used medical apps had a total of 845 medical apps installed on their personal device, accounted for by 56 specific apps. The British National Formulary (BNF/BNFc) app was installed on the personal mobile device of 96% of respondents that use medical apps. Forty percent of respondents had patient confidentiality concerns when using medical apps. Thirty-eight percent of respondents have used consumer instant messaging services, 6% secure specialist messaging services, and 29% smartphone photography when seeking patient management advice. Conclusion App use on the personal mobile devices, in the absence of access to institutional devices, was widespread, especially the use of a national formulary app. Instant messaging and smartphone photography were less common. A strategic decision has to be made to either provide staff with institutional devices or use software solutions to address data governance concerns when using personal devices. What is Known:• mHealth use by junior doctors and medical students is widespread.• Clinicians’ use of instant messaging apps such as WhatsApp is the widespread in the UK and Ireland, in the absence of alternatives. What is New:• Personal mobile device use was widespread in the absence of alternatives, with the British National Formulary nearly universally downloaded to physicians’ personal mobile devices.• A third of respondents used instant messaging and smartphone photography on their personal mobile device when seeking patient management advice from other teams in the absence of alternatives.

<span>A variety of internet-based applications are widely used in our animation activities because they provide free and useful services. These applications, such as Instant Messaging, can be run via the web, mobile, or computer-based devices. Therefore, the security and privacy of user data over these apps have been concerned in recent years because of sensitive and confidential information considerations. Consequently, many instant messaging applications, like Viber, have various security and privacy issues that need to be understood and resolved. Viber users reached 800 million, and they increased dramatically due to the efficient services that this app provides. Hence, a loophole in an application’s design may allow illegal access to the app and gain confidential and sensitive data. In this article, we proposed a security approach for Viber to safeguard user confidential data and sensitive information. The proposed approach involves two theoretical solutions: Short message service (SMS) authentication code and the physical hardware number to prevent illegal access to user data. Several scenarios are adopted to assess the proposed approach and achieve security and privacy for the user information.</span>

Full textAbstract:
Background Mobile instant messaging services are being increasingly used for educational purposes, but their effectiveness in medical education is not well known. We assessed whether students’ use of Kakao Talk (a mobile instant messaging service) during the early period of a week of clinical education influenced its use for academic purposes during a later period of the same week. Methods The online communication records of 151 third-year medical students (in 39 clinical education groups) who used Kakao Talk during clinical education were reviewed. The 39 groups were categorized as low, middle, or high according to the number of total chats (on all subjects, not just academic) per student over five days. The relationship between the number of total chats during the first two days and the number of academic chats during the last three days (of five-day chatroom weeks) was analyzed. Results The number of total and academic chats over all five days, the first two days, and the last three days was highest in groups with the highest number of total chats per student. Similarly, the highest number of students posting total and academic chats was found in these groups. In addition, the number of academic chats per student and the frequency of questions raised by students were also highest in these groups. During the last three days, the number of students posting total chats was lower than that during the first two days, and the number of academic chats per student posting academic chats was higher. The number of total chats on the first or second day positively correlated with the maximum value of academic chats on the third to fifth days. Conclusion High frequency mobile instant messaging use early on in clinical education might encourage its use for academic purposes during later periods.

Full textAbstract:
Working on team projects is a common feature in higher education as a way to foster team learning and collaboration. For a team to work well towards achieving project objectives, it is important that there is effective team communication. Conventionally, face-to-face interactions allow students to interact with each other in multiple communication channels, simultaneously sending and receiving verbal and nonverbal messages in real time. Today, modern mobile technology offers students a variety of alternative digital communication media for collaboration. Unlike a full-channel communication medium such as the face-to-face interaction, a digital communication medium like instant messaging does not normally transmit nonverbal cues. As a result, to compensate for insufficient nonverbal cues, users of instant messaging services have to put more effort and time into understanding each other. If more effort and time is required to understand each other better, then why is it that today’s students prefer instant messaging to face-to-face interactions for collaborative project work? To answer this question, this study conducted a questionnaire survey to collect responses from university students who have been involved in team projects. This study analysed students’ copresence (a second-order formative construct consisting of two first-order constructs: self-copresence and partner-copresence) and its relationships with media satisfaction and communication effectiveness. It investigated whether these relationships differed between the students who used instant messaging and those who used face-to-face interactions. In addition, this study also examined whether media satisfaction played a mediating role between copresence and communication effectiveness. The findings of this study could help explain how different communication media can facilitate teamwork in collaborative learning environments.

Full textAbstract:
Reducing the energy consumption of Internet services requires knowledge about the specific traffic and energy consumption characteristics, as well as the associated end-to-end topology and the energy consumption of each network segment. Here, we propose a shift from segment-specific to service-specific end-to-end energy-efficiency modeling to align engineering with activity-based accounting principles. We use the model to assess a range of the most popular instant messaging and video play applications to emerging augmented reality and virtual reality applications. We demonstrate how measurements can be conducted and used in service-specific end-to-end energy consumption assessments. Since the energy consumption is dependent on user behavior, we then conduct a sensitivity analysis on different usage patterns and identify the root causes of service-specific energy consumption. Our main findings show that smartphones are the main energy consumers for web browsing and instant messaging applications, whereas the LTE wireless network is the main consumer for heavy data applications such as video play, video chat and virtual reality applications. By using small cell offloading and mobile edge caching, our results show that the energy consumption of popular and emerging applications could potentially be reduced by over 80%.

This study examined the usability of five virtual reference services—instant messenger chat, e-mail, telephone, text messaging, and Skype videoconferencing—by having 31 undergraduate and graduate students evaluate the usability of the virtual reference services of two different universities. The study’s results suggest that user preference and satisfaction for virtual reference service are highly correlated with the service’s overall usability in terms of effectiveness and efficiency. Online chat was rated highest across all measures including satisfaction and seven different usability factors. Major implications of the study suggest that online chat is the virtual reference of choice for university students and that usability metrics are a good predictor of user preferences centered on high return on investment, speed of transaction, convenience, and minimal effort.

Full textAbstract:
Electronic communication technologies continue to change the landscape of reference services. For many users, virtual communication is the preferred means of conversing. Synchronous virtual reference, similar to other synchronous means of communication, is an important method for reaching students and for providing teaching and learning opportunities. Grounded Theory (GT) research provides a method for examining the transcripts of synchronous virtual reference. In this study, the library implemented the instant messaging (IM) application known as Meebo. Using the qualitative software ATLAS.ti, Iowa State University Library researchers uploaded, analyzed, and coded the instant messaging transcripts. From the analysis, a snapshot developed of the library’s central role in educating the university community about research resources. This paper describes ongoing challenges that occur during synchronous virtual reference interviews and staff training needs that cannot be captured by number crunching alone. Synchronous virtual reference can provide essential teaching and learning experiences that complement the educational mission of most research universities.

Full textAbstract:
Services and applications for real-time communications are developed during the last decade in two different contexts with almost opposite approaches. On the one hand, tele-communications companies have developed technologies supported the session initiation protocol (SIP), within the first place to re-implement the normal telephony service on the web, infrastructure, thus replacing the expensive circuit-switched network, but also enabling new communication channels like presence sharing and instant messaging. On the opposite hand, communities of open source developers have driven the evolution of open communication tools like e-mail and discussion systems towards the extensible messaging and presence protocol (XMPP). While the 2 worlds have virtually ignored one another for years, basically replicating the identical set of features, recent events within the industry have revealed a stimulating convergence between such technologies that within the near future is probably going to form them integrate. The project “Implementation of gateway between XMPP and SIP” is an effort to review various open source internet multimedia protocols like XMPP, SIP, RTP, MSRP et al. and their implementation into the $64000 environment and studying its actual working. The proposed system provides the features of audio call, and video call together with the features of conferencing, instant messaging, and presence.

Purpose In recent years, marketers have adopted new technologies to engage customers and better meet customer needs throughout the customer journey. The purpose of this paper is to investigate the impact of consumer engagement on satisfaction and behavior-based CRM performance generated by mobile instant messaging (MIM) services. The objective is to verify which aspects of consumer engagement generate satisfaction and optimize customer relationship management. Design/methodology/approach Data were made available for analysis from an online survey on customers who had been contacted or had contacted an organization by means of MIM. Based on literature analysis, relations between customer engagement dimensions, satisfaction and behavior-based CRM performance were studied by using structural equation modeling. Findings The cognitive engagement dimension and the emotional engagement dimension affect the level of satisfaction, but only the emotional engagement dimension has an effect on the behavior-based CRM performance, while social engagement does not affect satisfaction and CRM performance. Moreover, this study confirms the relationship between customer satisfaction and customer behavior-based relationship performance. Practical implications MIM used as support to the relationship with customers contributes to generating customer satisfaction and increases the value of service performance revealing it an excellent marketing tool in support of the customer journey. Originality/value This research extends our understanding of customer engagement in the ambit of the instant messaging application used for business that so far has not been investigated. This work shows how instant messaging can be a valid instrument for customer relationship management in optimizing the benefits deriving from the adoption of disruptive innovations.

Full textAbstract:
Aim/Purpose: The purpose of the current study is to explore positive and negative aspects of student-teacher communication via Facebook, as perceived by students in secondary education. Background: Student-teacher relationship is key to students’ cognitive, social and emotional development. In recent years, as social networking sites (e.g., Facebook) became popular, these connections have extended to such platforms. However, most studies of the use of social networking sites in the school context are pedagogically-driven, and research on the ways student-teacher relationship is facilitated by these platforms is meager. Methodology: We utilized a qualitative approach, analyzing middle- and high-school students’ responses to open-ended questions about this topic (N=667). We used both top-down and bottom-up analyses. Contribution: This study contributes to the growing literature about the overall impact of using social networking sites on the educational milieu. Specifically, it contributes by shedding light on students’ perspectives of that phenomenon. Insights from this study are important for educators and education policy makers. Findings: We found that student-teacher communication is mostly practical, although students who are not connected de facto but wish to connect romanticize it as more appealing. Furthermore, we found that students’ perceptions of negative aspects of such communication is complex, reflecting a deep understanding of the social media. Students were mostly concerned with privacy issues, and much less with other pedagogical, technological and social concerns. Altogether, it seems that the students acknowledge the benefits of connecting with their teachers online and implement this communication rather responsibly. Recommendations for Practitioners: We recommend that educators who wish to do so wisely use social networking sites and instant messaging services as part of their professional conduct, taking advantage of the benefits of using these platforms, and being aware of (and cautious about) potential drawbacks. We encourage educators to learn more about the potential uses of social networking sites and instant messaging services, and then to examine whether these uses may fit their educational agenda. We recommend education policymakers make evidence-based decisions regarding the use of social networking sites by teachers and encourage school communities to discuss these issues together. Recommendation for Researchers: As technology develops rapidly, we recommend researchers examine the topics raised in the current research with regards to other platforms, in order to better understand the technological aspects that may affect students’ perceptions of the use of social networking sites and instant messaging services to communicate with their students. We also recommend studying what types of resources are available to education policymakers when making decisions on relevant policies. Impact on Society: Understanding teens’ perspectives of their relationship with their teachers in today’s digital, networked world gives us a better understanding of this generation, hence may assist in planning and realizing a better educational system. Future Research: Future studies should focus on other social networking sites and instant messaging services, as well as on other countries and cultures.

Abstract The rapid development of network and computer technologies creates opportunities for offering advanced broadband multimedia services to a growing number of end users. Instant messaging and group communication services based on real-time video transmission based on global Internet resources are the most popular. The basic challenge related to the implementation of video transmission services is to ensure an appropriate level of quality and security (Quality & Security). The article presents a multi-criteria assessment of the impact of encryption protocols for multimedia video transmissions on the perceived quality of QoE (Quality of Experience) service implementation. The presented measurement method together with the proposed research methodology create the possibility of determining the likelihood of video service availability with accepted QoE in heterogeneous networks.

A Review of:
Chua, A. Y. K., & Goh, D. H. (2010). A study of Web 2.0 applications in library websites. Library & Information Science Research, 32(3), 203-211.
Objective – To determine the prevalence and use of web 2.0 applications in library websites and to determine whether or not their presence enhances the quality of the sites.
Design – Content analysis.
Setting – Public and academic libraries in North America, Europe, and Asia.
Subjects – A total of 120 academic and public library websites in English.
Methods – This study identified and selected library websites from academic and public libraries using a combination of directories, ratings reports, and ranking lists from three geographic regions. Over a four-month period in 2009, three coders conducted a three-step content analysis of the selected library websites. This analysis was conducted after having established inter-coder reliability using Cohen’s Kappa and analytic procedure familiarity, using a randomly selected pilot set of 30 library websites. The remaining 90 websites were evenly distributed among the three coders for analysis. They determined whether web 2.0 applications were present, examined how those applications were used, and gave an overall appraisal of website quality. Coders inspected library website links, conducted site searches, used search engines, and searched within major social networking sites to determine the presence of web 2.0 applications. A quality framework classification scheme was used during coding to identify how the web 2.0 applications were being used within library websites. This framework was established around four dimensions of library services: information acquisition (blogs and wikis), information dissemination (Rich Site Summary, or “RSS”), information organization (social tagging), and information sharing (social networking and instant messaging). A five-point Likert scale was also used in concert with a website quality evaluation framework to assess the quality of the library websites. This framework included three aspects of website quality: system quality, information quality, and service quality. A combination of statistical techniques such as Chi-square analysis, Cramer’s V, analysis of variance, Tukey’s statistic, and multiple regression were then used to analyze the findings.
Main Results – Web 2.0 applications have been adopted by libraries across North America, Europe, and Asia. The most popular web 2.0 applications were blogs (56.6%), RSS (50%), and instant messaging services (46.6%) while less prevalent were social networking services (20%), wikis (16.6%), and social tagging applications (16.6%). The extent of libraries’ adoption of web 2.0 applications also varied according to region. North American libraries used all web 2.0 applications most consistently and were more attuned to heavier users, particularly with regard to information sharing applications (e.g., instant messaging, social networking). European libraries lagged behind those in Asia in embracing information acquisition applications (e.g., blogs, wikis) but were comparable to other regions. Social networking services and instant messaging were strongly associated with region; RSS, blogs, and social tagging showed moderate to moderately strong associations; and only wikis did not demonstrate a statistically significant association with region.
This study also identified how web 2.0 applications were being used. Blogs were used to generate interest, engage users, and endear users to library personnel, while wikis culled resources from users thematically. RSS feeds communicated news, events or resource updates, and were also used in combination with library blogs. Social tagging invited users to save, organize, and share information, while some websites used librarian-generated tags for search and discovery or included them as tag clouds in library blogs. Instant messaging was used to assist users synchronously during scheduled timeslots; meanwhile, social networking sites offered alternate channels to communicate and build connections with users.
The authors found a relationship between website quality and the presence of web 2.0 applications based on the criteria presented in their quality evaluation framework. Applications facilitating information sharing (i.e., social networks and instant messaging) had a stronger influence on a website’s overall quality than those being used for information acquisition and dissemination (i.e., RSS, wikis, and blogs). Web 2.0 applications among academic and public libraries shared a similar level of presence on the library websites; therefore, the type of library is not associated with the quality of the library website. North American websites tended to be higher in quality than European or Asian library websites, and differences in quality between European and Asian sites were insignificant.
Conclusion – This study reveals that libraries in various geographic regions adopt web 2.0 applications differently. Web 2.0 applications in library websites enhance users’ experience with library resources and support their interests. Library websites are implementing web 2.0 applications in a myriad of ways, including using these applications in concert with one another to increase user engagement. The presence of web 2.0 applications strongly affects service quality but only weakly influences information quality.

Full textAbstract:
The Session Initiation Protocol (SIP) is a multimedia signalling protocol that has evolved into a widely adopted communication standard. The integration of SIP into existing IP networks has fostered IP networks becoming a convergence platform for both real-time and non-real-time multimedia communications. This converged platform integrates data, voice, video, presence, messaging, and conference services into a single network that offers new communication experiences for users. The open source community has contributed to SIP adoption through the development of open source software for both SIP clients and servers. In this paper, we provide a survey on open SIP systems that can be built using publically available software. We identify SIP features for service development and programming, services and applications of a SIP-converged platform, and the most important technologies supporting SIP functionalities. We propose an advanced converged IP communication platform that uses SIP for service delivery. The platform supports audio and video calls, along with media services such as audio conferences, voicemail, presence, and instant messaging. Using SIP Application Programming Interfaces (APIs), the platform allows the deployment of advanced integrated services. The platform is implemented with open source software. Architecture components run on standardized hardware with no need for special purpose investments.

Full textAbstract:
The rapid advancements in web and availability of growing number of free social networking tools have greatly influenced the present day communication mechanisms. These tools have provided cheaper, instant and faster methods of communicating information irrespective of geographical and time barriers. Users especially the younger generation is much familiar with the use of such tools and modern libraries are experiencing rapid changes in user perceptions and information seeking patterns. Owing to the ease of accessibility of plethora of information resources via cell phones, tablets using smart apps, libraries are revisiting their methods of information delivery. Many libraries are using social networking tools for handling user queries and advertising their library products especially in Virtual Reference Services (VRS). Virtual reference is reference service initiated electronically where patrons employ computers or other technology to communicate with public services staff without being physically present. Communication channels used frequently in virtual reference include chat, video-conferencing, voice-over-IP, co-browsing, e-mail, and instant messaging (Reference and User Services Association [RUSA] Guidelines, 2010). It primarily refers to a network of expertise, intermediation and resources placed at the disposal of someone seeking answers in an online environment (Berube, 2003). It has brought about tremendous change in the concept of reference services in terms of information dissemination and user satisfaction. Various initiatives have already been taken to develop standards, guidelines and procedures for setting up successful digital reference systems. Virtual reference has emerged as a new powerful method of delivering reference and information service to a vast number of clientele distributed globally. It includes seamless access to global resources and the collection of knowledge for reference access, coupled with complementary access to information on the internet. It has brought about tremendous change in the concept of reference services in terms of information dissemination and user satisfaction. The seamless influence of Social Networking tools on virtual reference is quite evident and trend is fast shifting towards incorporating such tools in libraries at global level. These tools not only solve the problems of communicating in real time environment in all modes ranging from instant messaging to audio/visuals but also provide ample opportunities for libraries to retain their users. The present work thus discusses the concept of Virtual Reference Service and possible use of different Social Networking tools in present day Virtual Reference Systems for successfully addressing user queries.

Full textAbstract:
Latest technologies of voice over IP (VoIP) and mobile messaging for smartphones messengers such as WhatsApp, Viber, Skype, etc., offer free-of-charge facilities of worldwide SMS, MMS, and voice calls to their users, unlike the traditional and expensive cellular or telephone networks’ services. Customers of the formerly mentioned messengers are estimated in millions because of the attractive features offered by them. However, these messengers face many cyber security threats and the required security features are either not available at all or are insufficient for efficiently countering the threats. Professionals working in the domain of cyber security are challenged by the devastating effects of distributed denial of service (DDoS) attacks on all major platforms including Apple Macintosh, Windows, Unix, and Linux. In this paper, we demonstrate the effect of DDoS attack on the performance of an IRC server using a test bed. We use a game theoretic model to analyze the feasibility of DDoS attacks on the IRC platform, keeping in view the attacker’s objective. The analysis will help the security experts to propose appropriate countermeasures to reduce the attackers’ utility, thereby making it less attractive for those attackers to launch the attack.

The rise of social networking has revolutionised how people communicate on a daily basis. In a world where more people are connecting to the internet, social networking services create an immediate communication link between users. Social networking sites provide multiple services which include emailing, instant messaging, uploading files, gaming and finding friends. Just as social networking has become a more popular method of communication in recent years, the ways in which people look after our health has also changed. People do not just rely singly on medical expert’s views anymore. They actively search for information on their own accord through the internet. Social Networking gives users both the option to gather, provide and comment on information. This research paper looks into if and how social networking can be successfully used within the health arena.

Full textAbstract:
Sessions generated by Instant Messaging and Peer-to-Peer systems (IM/P2Ps) not only consume considerable bandwidth and computing resources but also dramatically change the characteristics of data flows affecting both the operation and performance of networks. Most IM/P2Ps have known security loopholes and vulnerabilities making them an ideal platform for the dissemination of viruses, worms, and other malware. The lack of access control and weak authentication on shared resources further exacerbates the situation. Should IM/P2Ps be deployed in production environments, performance of conventional applications may significantly deteriorate and enterprise data may be contaminated. It is therefore imperative to identify, monitor and finally manage IM/P2P traffic. Unfortunately, this task cannot be easily attained as IM/P2Ps resort to advanced techniques to hide their traces including multiple channels to deliver services, port hopping, message encapsulation and encryption. In this paper, we propose an extensible framework that not only helps to identify and classify IM/P2P-generated sessions in real time but also assists in the manipulation of such traffic. Consisting of four modules namely, session manager, traffic assembler, IM/P2P dissector, and traffic arbitrator, our proposed framework uses multiple techniques to improve its traffic classification accuracy and performance. Through fine-tuned splay and interval trees that help organize IM/P2P sessions and packets in data streams, we accomplish stateful inspection, traffic re-assembly, data stream correlation, and application layer analysis that combined will boost the framework's identification precision. More importantly, we introduce IM/P2Ps "plug-and-play" protocol analyzers that inspect data streams according to their syntax and semantics; these analyzers render our framework easily extensible. Identified IM/P2P sessions can be shaped, blocked, or disconnected, and corresponding traffic can be stored for forensic analysis and threat evaluation. Experiments with our prototype show high IM/P2Ps detection accuracy rates under diverse settings and excellent overall performance in both controlled and real-world environments.

There is an increasing interest to the instant messaging applications, messengers. These applications allow us to interact with other users and include a functionality that can help us to implement bots that automate various business processes or provide information services. In this paper, we consider a specialized question answering system that uses today’s messaging services infrastructure to support university applicants. We gathered a corpus of applicants questions throughout two years and developed an information retrieval model that helps us to find similar questions in the corpus. Applicants can type their questions using a natural language without any formal requirements to phrase construction or using special templates. If the system is unable to find a relevant answer, the user can directly address the question to representatives of the university. The system was implemented with the use of modern cloud services that are provided by Amazon. We used serverless computations and NoSQL data bases, so we had to develop an architecture of the system in that way. Since the system contains sensitive personal data and provide personalized service, we must focus our attention on security. We proposed the means that must improve the safety of the system, more specifically, authentification process that can be used without the explicit use of personal data, however, this is a future work. At present we test our system and evaluate its quality of information retrieval.

Purpose – This study aims to investigate the different channels reference librarians receive reference inquiries from patrons in university libraries in Nigeria. Design/methodology/approach – A questionnaire was used to collect data on the various channels through which reference librarians received reference inquiries in Nigerian university libraries. The questionnaire was administered using an online method. Findings – It emerged that the face-to-face traditional reference desk was rated as the highest channel through which librarians receive reference inquiries in Nigeria, followed by library Facebook page and phone/short message service (SMS). Instant messaging (IM) and e-mail were identified as the least used channels by the patrons. The challenges mentioned include the absence of policy statements concerning virtual reference services; the lack of information and communications technology (ICT) skills on the part of librarians; slow Internet connectivity; power failures; management’s lack of support for emerging technologies; IM’s limitations; user’s expectations of instant answer; inarticulate requests; and lack of adequate current reference materials. Research limitations/implications – The findings are from a small sample size; therefore, the findings may not be substantial enough to generalize. Further study is necessary to determine if these results are consistent throughout other university libraries in Nigeria. Originality/value – The findings will inform university libraries in developing countries that are planning to adopt virtual reference services to deliver reference services to users anywhere, anytime.

Full textAbstract:
According to John Adams’ equity theory for employee motivation, employees place great importance on relative effort or input to its outcomes at the work place. However, as actual employee productivity is often difficult to estimate, anecdotal evidence suggests that employees frequently tend to compare the average number of hours worked per day. Geographically distributed or mobile workforces are of particular interest because such employees may not easily be able to physically observe their co-workers and, thus, estimate their relative effort. Instant Messaging (IM) has recently been adopted in many workplaces; yet, research on potential effects that IM presence awareness feature may have on employee attendance in a distributed workforce is virtually non-existent. This paper bridges that gap in the literature by presenting relevant findings, which have been derived from a 12-month-long ethnographic study of a large professional services organization. The authors show that, depending on the relative employee power relationship, presence awareness information may have significant positive or negative effects on a range of employee attendance dimensions.

Abstract. Background: Although increasing numbers of young people are seeking help online for self-injury, relatively little is known about their online help-seeking preferences. Aims: To investigate the perspectives of young people who self-injure regarding online services, with the aim of informing online service delivery. Method: A mixed-methods exploratory analysis regarding the perspectives of a subsample of young people who reported a history of self-injury and responded to questions regarding preferences for future online help-seeking (N = 457). The sample was identified as part of a larger study (N = 1,463) exploring self-injury and help-seeking. Results: Seven themes emerged in relation to preferences for future online help-seeking: information, guidance, reduced isolation, online culture, facilitation of help-seeking, access, and privacy. Direct contact with a professional via instant messaging was the most highly endorsed form of online support. Conclusion: Young people expressed clear preferences regarding online services for self-injury, supporting the importance of consumer consultation in development of online services.
