Internet Invariants: What Really Matters an Internet Society Public Policy Briefing
Internet Invariants: What Really Matters An Internet Society Public Policy Briefing 26 September 2016 Introduction Today’s Internet has We place an enormous amount of faith in the Internet, largely because it facilitates our transformed how more than two billion people connect and everyday lives. We instinctively trust that when we send an email, it will be received by communicate. And it will the intended recipient. When we type a domain name into a browser, we presume that continue to transform our economy, infrastructure, and the results will be what we are looking for. We can make these assumptions because social lives as cloud computing, Internet invariants ensure that if we send data, it arrives; and if we seek content, it will the Internet of Things, and be located. mobile devices evolve in ways we cannot yet imagine. We don’t often talk about how the Starting in the 1970s, a variety of protocols and network architectures were developed, network behind this technology works, just as most of us don’t but none became the driver of economic and social development that the Internet did. concern ourselves with where IBM’s Systems Network Architecture, for example, failed to take off because it could only electricity comes from, so long connect with hardware manufactured by IBM. The technical system that proliferated as our lights turn on. But as the Internet becomes an instead, and which remains at the foundation of the Internet, was TCP/IP because of its increasingly more pervasive and decentralized nature and underlying values of interoperability, flexibility, resilience, and critical piece of infrastructure, we need to understand both global reach. -

A FACULTY PERSPECTIVES and PRACTICES of SOCIAL PRESENCE in ONLINE POST-SECONDARY LEARNING ENVIRONMENTS a Dissertation SUBMITTED
FACULTY PERSPECTIVES AND PRACTICES OF SOCIAL PRESENCE IN ONLINE POST-SECONDARY LEARNING ENVIRONMENTS A Dissertation SUBMITTED TO THE FACULTY OF THE UNIVERSITY OF MINNESOTA BY Julie Ann Smith IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF EDUCATION Joyce Strand, Ph.D., Adviser April 2018 a Julie Ann Smith 2018 © b Acknowledgements This dissertation would not have been able without my patient adviser, Dr. Joyce Strand, who continued to support me throughout the years and help me to finally finish this research project. The last three years of trying to finish my dissertation included the caregiving to my mother and father. My father spent over two years in assistive care at the end of battling a long war with Alzheimer’s. He needed my mother’s help and she needed mine. This, and a concurrent divorce to my husband of 23 years, prolonged my ability to complete the writing of this dissertation, thus a long time had passed since the literature review. Many thanks go to my committee and doctoral chair who patiently provided me excellent advice in educational theory, interview and survey questionnaire revisions and/or dissertation guidance: Drs. Helen Mongan-Rallis, Craig Stroupe, Terrie Shannon, and Linda Deneen, and Chair Dr. Frank Guldbrandsen. Acknowledgements also go out to the faculty survey respondents and interviewees. Without their volunteer time, participation, and input, I would not have results to advance the study of social presence in the Community of Inquiry model. Additional thanks go to the faculty and staff and my cohort of the Education Doctorate in Teaching and Learning program at the University of Minnesota Duluth in the College of Education and Human Service Professions. -
Digital Image Steganalysis Techniques

Images are Abstract- The overwhelming growth in communication often used as a carrier because of their extensive technology and usage of public domain channels (i.e. availability with high resolution of pixels. Data Internet) has greatly facilitated transfer of data. However, embedding in a multimedia carrier like image may such open communication channels have greater vulnerability involve varying parameters such as different image to security threats causing unauthorized information access. Steganography is the art of hiding and transmitting data formats, different embedding algorithms and various through apparently innocuous carriers such as text, image, steganographic keys. This has made steganalysis a more audio or video in an effort to conceal the existence of the difficult and challenging task. Earliest work on secret data and the fact that communication is even taking steganalysis was reported by Johnson and Jajodia [9] and place. Steganalysis is an attack on steganography. Both Chandramouli et al.[10]. It has gained prominence in steganography and steganalysis have received a great deal of national security and forensic sciences as detection of attention from law enforcement and the media. In the past hidden messages can lead to the prevention of disastrous years many powerful and robust methods of steganography security incidents. Algorithms for Steganalysis are and steganalysis have been reported in the literature. -

The Effect of Social Control Models on Motivation and Use in Electronic Communication Infrastructures
THE EFFECT OF SOCIAL CONTROL MODELS ON MOTIVATION 103 The Effect Of Social Control Models On Motivation and Use In Electronic Communication Infrastructures Dan Manson Computer Information Systems Electronic communication can restrict organizational communication, or open communication channels to all employees regardless of status and personality. The purpose of this paper is to explore the relationships between social control patterns and electronic communication infrastructure use. Political, administrative, and computing infrastructure examples are used to provide initial understanding of infrastructure use. Social control models are used to provide insight into employee use of an electronic communication infrastructure. Case data from electronic communication systems is mapped to social control models to illustrate the effect of social control types on electronic communication use. Introduction A communications infrastructure provides an enabling platform for employees to share information to be used for decision-making, problem-definition, and coordination of organiza- tional behaviors. A functioning infrastructure enables the delivery of products and services facilitating human and cognitive processes adding value through information and knowledge exchange. In discussing the role of computing infrastructures, it is important to define infrastructure characteristics being considered. Computing infrastructure refers to the set of human and organizational resources that help make it simpler and faster for skilled people to use computerized systems (Kling, 1993). A computing infrastructure can consist of physical, technological and social characteristics. Physical characteristics can affect the ability to access the system. Technological characteristics involve issues of quality and reliability. Social characteristics address issues of information access and accountability. Physical and technological issues are driven by economic and technical issues, while social issues involve organizational issues. -
