The application of a social networking learning tool in a primary school within South Africa

Mohabier, Rushantha January 2017 (has links)
The Internet has evolved since its establishment, embedding itself in daily life and paving the way for social networking. The ability to connect and communicate has become seamless, allowing instantaneous access to the Internet and social networking sites. Social networking has become a global phenomenon, transcending boundaries and transforming mobile technology. It has gained an enormous following and become an indispensable technology. Social networking has expanded into a multi-faceted medium of communication, with an extensive online presence. The capacity to share information and knowledge is essential in building intellectual capital in professional and academic environments. This research project aims to explore the application of a social networking learning tool in a primary school within South Africa. This study explores social networking technologies and the opportunities they present in facilitating and supporting learning. Today’s youth are following technological advancements closely. At present, primary school and high school learners access a vast range of social networking sites, and the focus of this study is to understand if social networking sites can be applied to benefit learning. This study elected to explore the social networking as a learning tool in a primary school within South Africa. This research followed a mixed methods approach and its findings indicate that social networking has the potential to be applied positively as a learning tool by school learners, teachers and academic heads. This study revealed that learners and academics acknowledge the growth of social networking and recognise its potential benefits. This dissertation provides a foundation for schools and learning institutions in South Africa, Africa and the globe, to incorporate social networking into their learning framework in order to build and enhance learning. / Mini Dissertation (MBA)--Regenesys Business School, 2017. / This mini dissertation is donated by Regenesys Business School / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

Recent graduates’ usage and thoughts about LinkedIn

Larsen, Leonora January 2020 (has links)
This study examines how recent graduates with a Bachelor of Science in Media Technology use LinkedIn as a tool for job search and networking. It examines their thoughts around theirbehaviour in relation with how their behaviour can affect their future career opportunities. Thepurpose is to gain a deeper understanding of how LinkedIn is used which is based on the uses and gratifications theory. To examine this an abductive approach has been used, and four semistructured interviews have been done to gather data from the recent graduates. The study shows that recent graduates with a Bachelor of Science in Media Technology use LinkedIn as a tool for job search, but do not use the opportunity to network to its fullest potential. The recent graduates in this study are also passive users who use LinkedIn as a place to gather information that can be used later. This strengthens the earlier studies done in the field that students and recent graduates use LinkedIn passively and do not use the functions “liking”, “commenting”, “sharing” and “posting” to be more visible to the fullest. The recent graduates are aware of the opportunities LinkedIn provide and that it is beneficial for them to be more active there than they are today but find it difficult to know what they would contribute with by being more active.

1588-ENHANCED VEHICLE NETWORK CONCEPT DEMONSTRATION

Grace, Thomas, Roach, John 10 1900 (has links)
ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / CTEIP has launched the integrated Network Enhanced Telemetry (iNET) project to foster advances in networking and telemetry technology to meet emerging needs of major test programs as well as within the Major Range and Test Facility Base’s. This paper describes one objective of the vNET concept demonstration to provide a test vehicle instrumentation network architecture that can support additional capabilities for data access to the test vehicle. Specifically, this paper addresses the expansion of the current concept demonstration with the incorporation of the IEEE- 1588 standard as the basis for a network time distribution mechanism. Near-term network-based data acquisition systems will likely consist of a mix of standard IRIG 106 timekeeping and IEEE- 1588 timekeeping; in this paper we will examine the ramifications of using the two approaches with the same test vehicle instrumentation system.

iNET Standards Validation: End-to-End Performance Assessment

Moodie, Myron L., Araujo, Maria S., Grace, Thomas B., Malatesta, William A., Abbott, Ben A. 10 1900 (has links)
ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, California / The integrated Network-Enhanced Telemetry (iNET) project has developed standards for network-based telemetry systems. While these standards are based largely on the existing body of commercial networking protocols, the Telemetry Network System (TmNS) has more stringent performance requirements in the areas of latency, throughput, operation over constrained links, and quality of service (QoS) than typical networked applications. A variety of initial evaluations were undertaken to exercise the interfaces of the current standards and determine real-world performance. The core end-to-end performance initial evaluations focus collectively on the movement of telemetry data through the TmNS. These initial evaluations addressed two areas: end-to-end data delivery and parametric data extraction. This paper presents the approach taken by these ongoing efforts and provides initial results. The latest results will be presented at ITC 2010.

The Performance Evaluation of an OFDM-Based IP Transceiver at Eglin AFB

Berard, Alfredo, Cook, Paul, Roach, John 10 1900 (has links)
ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, California / The 46th Test Wing, 846th Test Support Squadron (846 TSS/TSI) at Eglin AFB is currently evaluating their airspace for the use of SOQPSK transmitters and receivers for telemetry. The Squadron will incorporate an IP-compatible OFDM transceiver from Teletronics Technology Corporation (TTC) that will provide a two-way communication channel for controlling configuration settings of the airborne SOQPSK transmitter and receiver. This provides an opportunity to evaluate the effectiveness of an airborne network instrumentation system and measure some critical parameters, with an opportunity to assess the performance and reliability of streaming telemetry and OFDM-based IP communication systems. This paper describes the experimental test setup created for this evaluation and summarizes the measurement and evaluation process.

CHALLENGES IN MONITORING MODERN INSTRUMENTATION NETWORKS

Blott, Michaela 10 1900 (has links)
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The adoption of commercial off the shelf networks, such as Ethernet, FireWire and FibreChannel, within the avionics community has dramatically changed the architecture of avionics busses and instrumentation networks. Higher bandwidth links and unified interconnects simplify existing infrastructure and wiring. But due to their point-to-point nature, networking topologies are fundamentally different from systems built on legacy bus technologies such as CAIS and MIL-STD-1553. Switched networks and ring topologies pose various challenges for the implementation of network monitoring hardware, and affect the design of bus monitors and distributed data acquisition systems. This paper discusses some of these issues. In particular we address deployment issues, architectural choices such as pass-through versus tap approach, as well as handling of bandwidth requirements and complex communication protocols. We illustrate on the basis of a FireWire monitoring system how these obstacles have been overcome for one given application.

Spinden, David, Jasper, Jeffrey, Kosbar, Kurt 10 1900 (has links)
International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / There are a number of telemetry applications where it would be helpful to have networks of sensors that could autonomously discover their connectivity, and dynamically reconfigure themselves during use. A number of research groups have developed wireless ad-hoc sensor network systems. This paper reviews the state-of-the-art in wireless ad-hoc networks, examining the features, assumptions, limitations and unique attributes of some of the more popular solutions to this problem.

Range-Video Network (RNET)

Berard, Alfredo, Buckley, Mark, Roach, John 10 1900 (has links)
ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, California / The deployment of network-based airborne instrumentation systems is leading to cost-efficient replacement of legacy instrumentation systems. One application of airborne data acquisition that has been developed and maintained separately from traditional avionics and orange-wire data acquisition systems is high-speed camera packages. The development of network-based instrumentation systems has led to an opportunity to unify these two previously distinct airborne data acquisition activities. This paper describes the range-video network-based instrumentation system (rNET) being implemented by the 46th Test Wing, 846th Test Support Squadron at Eglin Air Force Base, FL to replace the existing Airborne Separation Video System (ASVS).

Key Components of the iNET Test Article Standard

Grace, Thomas B., Kenney, Joshua D., Moodie, Myron L., Abbott, Ben A. 10 1900 (has links)
ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The integrated Network-Enhanced Telemetry (iNET) Test Article Standards Working Group (TASWG) has developed a standard for Telemetry Network System (TmNS). The introduction of Internet Protocol (IP) networks on test ranges has created the potential for greater flexibility in the telemetry environment. This paper discusses the rationale for particular decisions concerning key components mandated by the standard. Performance implications concerning the mandates of the standard are also described. As an educational aid, examples of TAS-based processing philosophies and data structures have been constructed. These examples, including sending and receiving messages, are shown to reinforce understanding core concepts of the standard.

The Application of a Distributed Computing Architecture to a Large Telemetry Ground Station

Buell, Robert K. 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / The evolution of telemetry ground station systems over the past twenty years has tracked the evolution of the mini-computer industry during that same time period. As the various mini-computer vendors introduced systems offering ever increasing compute power, and ever increasing capabilities to support multiple simultaneous users, the high end of the telemetry ground station systems offered by the industry evolved from single stream, single user, raw data systems to multi-user, multiple stream systems supporting real-time data processing and display functions from a single CPU or, in some cases, a closely coupled set of CPUs. In more recent years we have seen the maturation of networking and clustering concepts within the digital computer industry to a point where such systems coupled with current workstation technology, now permit the development of large telemetry ground station systems which accommodate large numbers of simultaneous users, each with his or her own dedicated computing resources. This paper discusses, at a hardware block diagram and software functional level, the architecture of such a distributed system.
