Full textIn libraries around the world there are people asking librarians for research assistance. As technology has advanced and communication strategies have moved outside the physical library buildings, librarians now respond to reference queries online. This study analyzed two forms of virtual reference; instant messaging (IM) and log-in chat. The purpose of this study was to find out if there is any inherent difference between the way the patrons or the librarians used these two virtual services.
An exploratory research design focused on numerous aspects of virtual reference communication. During the spring terms of academic years 2011 and 2012 at a community college, 1,341 transcripts of IM and log-in chat sessions were recorded. Using a systematic sampling process, 320 transcripts were sampled and their content analyzed.
Findings indicate that a length of the transaction significantly affected the outcome of all transactions. Log-in chats were generally longer than IM chats and it was found that; they were more complicated, the librarians were more responsive and friendly, patrons were more satisfied and the librarian was generally able to conduct a reference interview more often. Additionally the findings indicated that both IM and log-in chat were very similar in three aspect; patron formality, completeness/accuracy of the librarians' answer and the reference interview adding/changing or clarifying the patrons question.
There were four major conclusions of this study: The log-in chat portal had longer online reference transactions and better overall outcomes; instant messaging portal queries, although similar in many aspects to log-in chat, were ultimately treated in a less formal manner by patrons; librarians gave reference interviews and complete/accurate answers equally in both platforms and there were similar overall success rates in both platforms.
Based on the findings in this study it is recommended that academic libraries serving a general population of students use both the IM and log-in chat portals on their library websites. Patrons appear to appears to be using each portal for different and equally important reasons. Further study of virtual communications practices is needed to enhance the findings of this study as more institutions expand their patron base beyond those who can physically meet with a reference librarian.

Full textCommunication tools such as text-based instant messaging, voice and video relay services, real-time video chat and mobile SMS and MMS have successfully been used among Deaf people. Several years of field research with a local Deaf community revealed that disadvantaged South African Deaf
people preferred to communicate with both Deaf and hearing peers in South African Sign Language as opposed to text. Synchronous video chat and video
relay services provided such opportunities. Both types of services are commonly available in developed regions, but not in developing countries like South
Africa. This thesis reports on a workaround approach to design and develop an asynchronous video communication tool that adapted synchronous video
codecs to store-and-forward video delivery. This novel asynchronous video tool provided high quality South African Sign Language video chat at the
expense of some additional latency. Synchronous video codec adaptation consisted of comparing codecs, and choosing one to optimise in order to
minimise latency and preserve video quality. Traditional quality of service metrics only addressed real-time video quality and related services. There was no
uch standard for asynchronous video communication. Therefore, we also enhanced traditional objective video quality metrics with subjective
assessment metrics conducted with the local Deaf community.

IM (Instant Messaging) offers users the service of exchanging text messages, audios, videos and files instantly on a network. For many network users, IM becomes an indispensable tool for daily communications. So far, most sets of the IM software transmit instant messages in plaintext, and without a secure flawless authentication scheme between the server and users. These Flaws make the IM systems prone to eavesdrop attack, impersonation attack and server spoofing attack, which poses a threat to the users’ privacy. So it is necessary to enhance the security of IM systems by providing a flawless authentication scheme and the encryption approaches to secure the IM content in no time. This study, based on the three-party encrypted key exchange (EKE) protocol of Lee et al., designs a secure IM protocol and implements the IM system in the Java platform to verify that the proposed IM protocol is feasible. The proposed IM protocol not only enables the server and users to authenticate each other mutually but also generates a session key between the two users on communication after authenticating the validity of their identification. This session key is used to encrypt the IM content, protecting the instant messages sent on a network from being intercepted or misused by attackers, and therefore, meets the security requirements: authentication, confidentiality, integrity, and forward secrecy. In the security analysis, we also analyze several commom network attack methods and provide users with a more secure IM protocol.

Among the domestic people who use Internet activities today, the population of utilizing the Instant Messaging (IM) has been tremendously increased up to 80% in 2008. With the rapid population growth of IM usage, the IM which is originally used for the personal communication tool has gradually become one of the necessary gadgets for the enterprises now. It has already caused unprecedented influence on the way how people communicate with each other. In the past, researches on IM just only focused on user’s behavior or communication satisfaction. However, the studies about the website in IM online customer service are rarely being investigated so far. The purpose of this study is to predict customers’ determinants for adopting Instant Messaging in Online Customer Service based on Technology Acceptance Model (TAM). Moreover, the research model adds two additional factors, compatibility and trust, to further analyze the potential reasons which affect the customers’ determinants. This study collects empirical data from the customers of the website. A total of 166 completed questionnaires were returned. The empirical results show that the effects of the two original explanatory variables, perceived usefulness and perceived ease of use, have a significant impact on the attitude and intention of the customers to use the IM online customer service. Additionally, the new adding variable, trust, is critical to affect the customers’ intention to use this service. Instead, the compatibility does not show a crucial influence on the customers. However, the compatibility plays a critical role in intention when trust acts as a mediating variable. In summary, the study shows that the customers are willing to use the IM online customer service. The customers’ determinants to use IM online customer services are based on perceived usefulness, perceived ease of use, attitude and trust. Besides, it provides suggestion that enterprises can implement this service in the future in order to not only reduce the cost of communication, but increase the efficiency of communication and competitiveness as well.

Mobile Instant Messaging (MIM) is a service that uses mobile devices to send instant messages through a communication network, prolonged or frequent use of it may cause dependence. Currently, LINE is the most popular and widely used MIM in Taiwan, because it offers diversified communication methods and a wide range of community services. This study aims to investigate the factors that caused techno-dependence, and the impact that such dependence may have on users. This study adopted the questionnaire approach to collect responses from actual LINE users. The study collected 663 valid questionnaires. Structural equation modeling (SEM) was used for path analysis, and the eight hypotheses proposed in this study were examined. Furthermore, based on Stafford et al.’s (2010) techno-dependence research, this study combined the belongingness theory and the stress-strain-outcome (SSO) model to explore the positive and negative consequences of techno-dependence, and their effects on satisfaction and continuous usage intentions. Results showed that users developed techno-dependence in LINE situations involving people, fun, information, and work. In terms of the consequences for techno-dependence, this study found that belongingness was a positive consequence of techno-dependence. Dependence on LINE enhanced users’ feelings of belongingness with friends, colleagues, and family. Belongingness enhanced users’ satisfaction and continuous usage intentions. This study found that social interaction overload, which resulted from social message overload and social demand overload, was a negative consequence of techno-dependence. Users’ perception of social interaction overload induced users to generate emotional exhaustion, which negatively affected users’ satisfaction and continuous usage intentions. In summary, this study suggests that techno-dependence can increase the user’s social belongingness and result in positive emotions. It can also increase the user’s social interaction overload and result in negative emotions. Users’ evaluations of MIM were simultaneously affected by these social and emotional factors. Implications for theory and practice, and suggestions for future research, were also discussed

Full textOnline shopping is rapidly increasing, creating new opportunities and challenges in the highly-competitive services market. In this context, companies are trying to come with new ways of connecting, as consumers seek easier and faster ways of interacting. This study employs the unified theory of acceptance and use of technology 2 (UTAUT2) as the theoretical paradigm and extends it, to explore the key factors influencing the uptake of mobile instant messaging applications in online customer service, by introducing social presence as a crucial construct. The data was collected from an online questionnaire conducted to 222 Portuguese mobile instant messenger’s users. Structural equation modelling (SEM) was used to verify and validate the research model. The results showed that performance expectancy represents the greatest influence on users’ intention to engage in online customer service through mobile instant messaging. In addition, social presence was found to directly impact behavioural intention and indirectly, through the mediation of performance expectancy and habit. This study fills the gap in the literature, where little attention has been devoted to examining the use of mobile instant messaging applications by organizations for online customer service. The findings will help practitioners make appropriate strategies for this new channel.

At present, MSN and Yahoo Messenger have substituted ICQ as leading IM software, while lot of IM software such as Skype, QQ, and Google Talk attempt to expand their market shares. By combining the perspectives of diffusion of innovation (DOI), technology adoption model (TAM), and network externality, this thesis aims to explore why the adopt rate of IM grows so quickly, how an IM software can obtain competitive advantages over others, is there any effective business strategy existing in web-based communication service market. As a result, the findings can be referred as valuable cues for industries to effectively develop their marketing strategies. By empirically investigating samples of IM Taiwanese users in terms of their pre-use status, in-use situation, characteristics, perception, using willingness, and post-use continuous behavior, four main results have been identified herein. First, compatibility, ease-of-use, and subjective norms significantly influence the adoption willingness of IM. Second, previous experience, innovative features, and social perception significantly impact perceived compatibility and subjective norms; previous experience and innovative features significantly impact perceived ease-of-use. Third, agenda, age, and occupation significantly affect perceived compatibility, and the average daily time of using Internet remarked influences perceived ease-of-use and subjective norms. Fourth, network externality, compatibility, and perceived ease-of-use greatly affect adoption willingness of IM, while network externality and adoption willingness extensively influence the continuous adoption willingness.

Full textNowadays, due to globalization, increase of competitiveness and organizational structure, people are required to move around the globe in order to achieve their goals. The need to commute is based on the necessity to meet with collaborators, clients, prospect clients or any other person that is on a different location. Since this need for travelling consumes a large amount of money and time resources, it is necessary to find an alternative that allows people to meet and collaborate anywhere. Consequently, this internship attempts to overcome this collaboration need with two prototypes. The first one is a Web Application that is interoperable with other types of devices in order to maximize the opportunity to collaborate. Although it is not possible to implement all functionalities in every type of device, joining a video conference from a cell phone only with audio is still more valuable than not joining at all. The only way of making all of this possible is using a mature architecture such as the IP Multimedia Subsystem. The second one is an Android Application capable of communicating with XMPP Networks.
