Approved for public release, distribution unlimited / Current chat and instant messaging (IM) solutions within the DoD have created problems with information security and interoperability. Though Extensible Message and Presence Protocol (XMPP) is the only mandated chat and IM protocol in the DoD, the majority of the military still operates alternate nonstandard solutions that prevent interoperability and lack appropriate security assurances. XMPP is a streaming XML protocol used for multi-user text chat and Instant Messaging (IM). XMPP supports a large set of administrative and user features, valuable to military chat and IM users. As an open standard, XMPP is also extensible to allow for development of military-specific chat and IM requirements. XMPP protocol also provides significant extensibility to allow for greater command and control and other operational capabilities. This work demonstrates the use of XMPP to route XML-expressed Distributed Interactive Simulation (DIS-XML) data to conduct distributed modeling and simulation. This work also demonstrates the use of XMPP as a generalized XML message-routing framework in conjunction with XML-expressed military data models, such as the Joint Consultation Command and Control Information Exchange Data Model. Also presented in this thesis is an XML document based chat data logger, designed to support persistent operations using distributed chat architecture. Experiments conducted with Navy Exercise Trident Warrior 2006 demonstrate the value of such a framework, as well as the value of XML document-based chat data logging. Results indicate that implementation and extension of XMPP has significant value for enhancing command and control. These features, along with the benefits of the adoption of open standard solutions, make XMPP an essential technology for adoption in todayâ s operational command and control suites.

The increasing popularity of Instant Messaging (IM) among adolescents in North America (Kids' Take On Media, 2003; Lenhart, Ranie & Lewis, 2001; Tagliamonte & Denis, 2006) is prompting two educational debates. One debate contests whether IM is more like speech or writing (e.g. Tagliamonte & Dennis, 2003). The second debate disputes whether IM has a positive or negative effect on school writing (e.g. O’Connor, 2005). This thesis addresses these debates from a New Literacies Studies (NLS) stance. It reports on a qualitative study of the perspectives and literacy practices of high school students. The purpose is to examine how IM shapes student writing and perception of literacy. The study focuses on the communication that transpired between five experienced IM users—one researcher and four adolescent participants—during a six-week IM writing group. Findings indicate the participants regard IM as a space for written slang; a space where speech and writing merge. Sensitive to context, the participants note that they can switch language registers to accommodate their audience, but they think confusion between registers may be a possibility. They demonstrate an attitude of “linguistic whateverism” (as described by Baron, 2002) when writing in the context of IM to increase efficiency, but they do not use as many acronyms as expected. The “whatever” attitude is linked to mistakes in writing, but it also exposes them to a sense of freedom and enjoyment. In general, IM provides these students with a new purpose for language, which they perceive as disconnected from school literacy. The findings suggests that IM language is a hybrid of speech and writing, and connecting IM with school writing (both literally and figuratively) may help teachers be more effective in making school writing processes more relevant to students’ lives. While making this connection, it is important for teachers to emphasize the plurality of literacies and the importance of revising and editing “finished” writing. In conclusion, this thesis considers new opportunities and concerns for writing pedagogy and new prospects for language research. / Thesis (Master, Education) -- Queen's University, 2008-01-25 11:40:10.265 / Queen's University; Ontario Graduate Scholarship Program (OGS)

Abstract ¡§Human Needs Drive Technology.¡¨ Since internet comes into action, it brings dramatic changes in human culture. Internet technology does not change only the way of communication or how the business activity moves, but it also creates a whole new life model. Especially after the rising of instant messaging software, the real-time communication model is formed. Many studies on instant messaging focuses on the pros and cons of the software itself and the benefits it has generated. Besides, their study groups are more focused on people with specific roles, such as sales, marketing staff, or students. The results obtained often do not cover the aspects on people with multi-roles. This study report takes EMBA students as the object of study, mainly because they carry the characteristics of both a student and a business man, whose behavior may lead us to see the general value that the instant messaging can generate. The study focuses on the behavior and motivation of EMBA students using instant messaging software, and it further discusses the changes that the instant messaging can bring at their study and their jobs. 9 EMBA students are chosen to conduct the case study, interviewed face-to-face and via instant messaging. The study finds that the instant messaging software have brought very positive benefits for EMBA students in their jobs, school work, and even in their interaction with their family.
