Examining the issues & challenges of email & e-communications. 2nd Northumbria Witness Seminar Conference, 24-25 Oct 2007 Northumbria University, Newcastle upon Tyne.

These proceedings capture the content of the second Witness Seminar hosted by Northumbria University’s School of Computing, Engineering and Information Sciences. It followed the success of the first witness seminar in terms of its format and style but differed in that it focused on one topic - managing email and other electronic communications technologies from a records perspective. As before the witnesses were invited to share their views and opinions on a specific aspect taking as their starting point a pertinent published article(s). Three seminars explored the business, people and technology perspectives of email and e-communications, asking the following questions: What are the records management implications and challenges of doing business electronically? Are people the problem and the solution? Is technology the problem or panacea? The final seminar, 'Futurewatch', focused on moving forward, exploring new ways of working, potential new technologies and what records professionals and others need to keep on their radar screens

New Trends in Quantum Computing

Classical and quantum information are very different. Together they can perform feats that neither could achieve alone, such as quantum computing, quantum cryptography and quantum teleportation. Some of the applications range from helping to preventing spies from reading private communications. Among the tools that will facilitate their implementation, we note quantum purification and quantum error correction. Although some of these ideas are still beyond the grasp of current technology, quantum cryptography has been implemented and the prospects are encouraging for small-scale prototypes of quantum computation devices before the end of the millennium.Comment: 8 pages.

IADIS Press.The Information Technology Outsourcing (ITO) model has been a trend in recent decades, becoming the dominant trend in contemporary outsourcing scenario. Millennials will soon, globally, be the majority of the workforce, having a particular way of relating to organizations and to work itself as no previous generation did. Information technologies continue to employ more and more human resources, having an increasing demand and a shortage of competent resources. It is therefore important to rethink current Human Resources Management (HRM) models and design a new strategic and appropriate model to accommodate and anticipate the needs of managers and monitor the development of this generation as Information Technology (IT) professionals. The intersection and analysis of the Information and Communications Technologies (ICT), millennials, Human Resource Management, outsourcing and organizations is the objective of this study, to identify the most relevant articles regarding millennials as outsourced IT professionals.publishersversionpublishe

Beaconing Approaches in Vehicular Ad Hoc Networks: A Survey

A Vehicular Ad hoc Network (VANET) is a type of wireless ad hoc network that facilitates ubiquitous connectivity between vehicles in the absence of fixed infrastructure. Beaconing approaches is an important research challenge in high mobility vehicular networks with enabling safety applications. In this article, we perform a survey and a comparative study of state-of-the-art adaptive beaconing approaches in VANET, that explores the main advantages and drawbacks behind their design. The survey part of the paper presents a review of existing adaptive beaconing approaches such as adaptive beacon transmission power, beacon rate adaptation, contention window size adjustment and Hybrid adaptation beaconing techniques. The comparative study of the paper compares the representatives of adaptive beaconing approaches in terms of their objective of study, summary of their study, the utilized simulator and the type of vehicular scenario. Finally, we discussed the open issues and research directions related to VANET adaptive beaconing approaches.Ghafoor, KZ.; Lloret, J.; Abu Bakar, K.; Sadiq, AS.; Ben Mussa, SA. (2013).

Information and Communications Technology in Developing, Emerging and Transition Economies: An Assessment of Research

Information and communications technology (ICT) is a crucial driving force in economic globalization and the principal enabler in building a highly connected world. However, despite the ever-increasing importance of ICT in developing economies, the mainstream information system research remains focused on ICT in the limited number of highly developed countries. Comparatively little research is being reported that specifically addresses the issues that arise from using ICT in developing, emerging and transition economies. In this paper, we review twenty-five papers in this topic area that have been published in past proceedings of the Americas Conference on Information Systems (AMCIS). Based on this review, trends and shortcomings in the existing research are discussed and new research opportunities are proposed

Experimental investigation of pulsed entangled photons and photonic quantum channels

The development of key devices and systems in quantum information technology, such as entangled particle sources, quantum gates and quantum cryptographic systems, requires a reliable and well-established method for characterizing how well the devices or systems work. We report our recent work on experimental characterization of pulsed entangled photonic states and photonic quantum channels, using the methods of state and process tomography. By using state tomography, we could reliably evaluate the states generated from a two-photon source under development and develop a highly entangled pulsed photon source. We are also devoted to characterization of single-qubit and two-qubit photonic quantum channels. Characterization of typical single-qubit decoherence channels has been demonstrated using process tomography. Characterization of two-qubit channels, such as classically correlated channels and quantum mechanically correlated channels is under investigation. These characterization techniques for quantum states and quantum processes will be useful for developing photonic quantum devices and for improving their performances.Comment: 12 pages, 8 figures, in Quantum Optics in Computing and Communications, Songhao Liu, Guangcan Guo, Hoi-Kwong Lo, Nobuyuki Imoto, Eds., Proceedings of SPIE Vol. 4917, pp.13-24 (2002

Nowe zasady komunikacji elektronicznej w postępowaniu sądowoadministracyjnym

The New Rules of Electronic Communications in Administrative Court ProceedingsThe purpose of this review is to analyse the legal regulations introducing new rules for electronic communications in administrative court proceedings as of 11 February 2017 and to demonstrate the benets but also risks resulting from the process of informatisation. One of the signicant changes refers to the admissibility of  submitting electronic-format pleadings at courts.On the one hand, the broader implementation of information technology in administrative court proceedings may contribute to accelerating such proceedings, but on the other hand. It may involve some risks such as technical issues related to hardware and so ware, problems with interpretation of new IT terms, or problems with impersonation or unauthorised disclosure of personal dat

Electronic evidence in criminal proceedings

The research question central to the thesis is stated as follows: what are the implications of new technological phenomena in South African law to the existing legal frameworks in relation to (i) investigatory powers of law enforcement and security and intelligence agencies to obtain electronic evidence, and (ii) its subsequent admissibility in criminal proceedings? Written with an emphasis on South African law, but also taking into account aspects of foreign and international law, the thesis seeks to investigate how our existing legal frameworks which regulate the use of and access to electronic evidence in criminal proceedings, including its admissibility, integrate and adapt to challenges raised by new and rapidly changing technological developments. The thesis provides a critical analysis of the existing legal framework regulating certain key investigative powers of law enforcement and security and intelligence agencies in the current modern environment of the information age in which they operate. Key among them is the Regulation of Interception of Communications and Provision of Communication-Related Information Act 70 of 2002. New technology has not only increased opportunities for criminal activity, it has also created opportunities for law enforcement and security and intelligence agencies to have access to more sophisticated and new capabilities. The range of intrusive capabilities now available to law enforcement and security and intelligence agencies triggers a range of issues and challenges for individual rights, including how those capabilities are used in investigation activities, the scale of their use, the extent to which such capabilities intrude on privacy rights, legislative authority for their use and safeguards that constrain and regulate such new technological capabilities. The challenges of regulating investigative powers in an era of new and fastpaced technological developments is explored in relation to (i) interception of communications (ii) acquisition and retention of communications data, and (iii) access to encrypted information. The introduction of electronic evidence in criminal legal proceedings raises unique challenges in the South African law on evidence. The most interesting perhaps is the extent to which the nature of the evidence presented, in this instance electronic evidence, impacts on admissibility in criminal proceedings. Potential anomalies arise as the relevant legislation, the Electronic Communications and Transactions Act 25 of 2002, is based on an electronic commerce model law concerned with commercial activities. In this regard, two separate issues are the focus of research interest. The thesis offers a rethinking of (a) admissibility of electronic evidence and (b) its weight. The meaning and application of certain statutory provisions, insofar as it applies to electronic evidence as hearsay or real evidence, or both, are key and controversial issues. Another relates to the business records exceptions, which directly translated for electronic records appears to have created a problematic presumption. On matters of evidential weight, there is no ‘one-size-fits-all' approach that will work. While a robust consideration of authentication is required in the court's assessment of evidential weight of electronic evidence, it should not be subject to inflexible tests that make it difficult for authentic electronic evidence to be admitted into evidence. A central premise of the thesis is that evolving technological phenomena can and do present challenges to existing legal concepts on evidence and the investigatory powers of law enforcement and the security and intelligence agencies to obtain electronic evidence and for its admissibility in criminal proceedings. This is done in the context of understanding whether South African law has developed appropriately in response to advancements in technology. In the final analysis, the thesis considers appropriate and meaningful reform towards a modern and transparent legal framework in South African law

Communication-oriented smart grid framework

Upgrading the existing electricity grids into smart grids relies heavily on the development of information and communication technology which supports a highly reliable real-time monitoring and control system as well as coordination of various electricity utilities and market participants. In this upgrading process, smart grid communication is the key to success, and a simple but complete, innovative but compatible high-level communication-oriented smart grid framework is needed. This paper proposes a simple and flexible three-entity framework, so that devices employing the existing technologies are supported and can interoperate with those employing new technologies. © 2011 IEEE.published_or_final_versionThe 2nd IEEE International Conference on Smart Grid Communications (SmartGridComm 2011), Brussels, Belgium, 17-20 October 2011.
