Supervisory Control And Data Acquisition (Scada) Systems, George H. Baker, Allan Berg

George H Baker

Our critical national infrastructure systems have become almost universally dependent upon computer-based control systems technically referred to as supervisory control and data acquisition (SCADA) systems. SCADA systems evolved from the telemetry and event-alarm systems developed in the early days of utilities. With the widespread use of SCADA systems, computers have become the "basis element" for much of our critical infrastructure. Thus, the disruption of controlling computer terminals and networks due to natural disasters, electric power failure, accidents or malicious activity can have catastrophic consequences.

Delivering On The 256 Qam Promise, Ron D. Katznelson

Ron D. Katznelson

The accumulation of degradation factors in the downstream channels is reviewed with focus on headend/hub transmission-related noise aggregation due to a plurality of downstream Quadrature Amplitude Modulation (QAM) transmitters and upconverters. Substantial increase in the number of QAM transmitters based on frequency agile upconverters is expected. Unlike fixed channel upconverters, these do not have narrow band filters at their output, consequently imparting appreciable levels of broadband noise on the network when several such units are combined. Based on these factors and other noise contributions, it is shown that additional impairments due to fluctuations associated with composite distortion terms on the …

Specifying And Measuring Aggregate Broadband Noise Of Catv Modulators And Upconverters, Steven I. Rubin, Andre Basovich, Brani Petrovic, Ron D. Katznelson

Ron D. Katznelson

This paper discusses the practical limitations and the subtle assumptions that must be incorporated into the specifications and measurements of Aggregate Broadband Noise of CATV upconverters and digital QAM transmitters. Considerations that govern the accuracy and measurement dynamic range required for such Aggregate Broadband Noise measures are identified. Novel methods involving the separation of the Aggregate Broadband Noise measure into its composites, namely, modulated distortion noise components and other broadband noise components are discussed. Optimal ways in which such measurement techniques have been automated to enable rapid and efficient evaluation of transmitter devices are also presented along with examples of …

Selling Canada To Canadians: Collective Memory, National Identity, And Popular Culture, Emily West

Emily E. West

Two media endeavours, the Heritage Minutes and the CBC documentary Canada: A People’s History, hope to serve as a corrective to Canadians’ lack of interest in their history and to bolster national identity. However, the producers do not want to appear propagandistic in a country where there is conflict about what the shape of the nation should be. They accomplish this by appealing to the “on the spot” authority of journalistic representation and the emotional immediacy of dramatic story-telling. They also emphasize the multi-cultural and multi-perspectival nature of Canada’s past. However, ultimately these efforts exist within a larger narrative about …

Statistical Properties Of Composite Distortions In Hfc Systems And Their Effects On Digital Channels, Ron D. Katznelson

Ron D. Katznelson

The statistical properties of Composite Triple Beat (CTB) and Composite Second Order (CSO) distortion terms associated with the analog channels carried on Hybrid Fiber Coax (HFC) are presented. Both simulation and measurement results show that such distortion components falling on individual channels have amplitude Probability Density Function that is nearly Rayleigh distributed (having a Standard Deviation of 5.7 dB). It is shown that both CTB and CSO components have peak envelope power fluctuations that exceed their average (measured) power levels by more than 15 dB. The temporal statistical properties of these distortion components demonstrate peak envelope power fluctuations with characteristic …

Active Cultures: Here Come The Hacktivists, Eben English

Eben English

For some, the word "hacker" might conjure visions of a four-eyes, pocket-protected malcontent. But nowadays there's a new breed of hacker, one bent on using his powers for good instead of evil: the hacktivist.

Media Advisers - Shadow Players In Political Communication, Richard Phillipps

Richard Phillipps

Extract:Synopsis:It is a commonplace in political communication that the news media mediate wider political realities to their audiences. The extent to which that news content is itself mediated by others is a more ambiguous and problematic area. Perhaps because it is rarely directly visible to the public, the work of media advisers or press secretaries has become the subject of much speculation, with sweeping claims about their power. This thesis systematically explores the role of media advisers, a backroom group sometimes labelled spin-doctors or minders. Until now, this pivotal group in democratic political communication has not been the focus of …

Das Innovationsverhalten Der Deutschen Softwareindustrie, Michael Friedewald, Knut Blind, Jakob Edler

Michael Friedewald

In this article we present the results of two empirical studies focusing on the structure and extent of the innovation activities of the German Software Industry and analyze distinctive features of Software Innovations. We distinguish the activities of the primary (core) Software Industry and secondary industries such as Mechanical and Electrical Engineering, Motor Industry and Telecommunications. A special focus is put on the question if innovations in Software are sequential, on the role of Open Source Software and the importance of inter- operability.

Another Part Of The Risk Communicatin Model: Analysis Of Risk Communication Process And Message Content, Michael J. Palenchar, Robert L. Heath

Michael J Palenchar

The authors undertook a study to define the messages that exist in 2 communities of risk (e.g., high concentration of chemical facilities) using the principles of fantasy theme analysis and symbolic convergence theory. Through several methodological steps including a document review, interviews, focus groups, and a telephone survey (N = 450), the researchers determined the messages that dominate in the community, and were able to segment them into rhetorical visions based on master analogues. Analysis indicated that persons who adhere to different perspectives or opinions (measured as rhetorical visions) experience different amounts of uncertainty, control, and support or opposition for …

Scholar Or Baller In American Higher Education? A Visual Elicitation And Qualitative Assessment Of The Studentathlete's Mindset, Keith Harrison

Dr. C. Keith Harrison

Eminent scholar Harry Edwards (2000) has articulated three major realities of African American males in sports: a) The presumption of innate, race-linked black athletic superiority and intellectual deficiency; b) media propaganda portraying sports as a broadly accessible route to African American social and economic mobility; and c) a lack of comparably visible, high-prestige African American role models beyond the sports arena. Driven by labeling theory (Becker, 1963; Goffman, 1959), eight African American male student athletes were surveyed and interviewed. The last two points of Edwards' scholarship were investigated. "We have pretty good historical data and quantitative data about African American …

African American Racial Identity And Sport, Keith Harrison

Dr. C. Keith Harrison

The purpose of this paper is to attempt to synthesize and apply African American racial identity theory and related research to the development of sport and physical activity patterns and preferences in African American youth. Historically the African American over-representation in particular sports phenomena has been examined genetically, anthropocentrically, physiologically, sociologically, and psychologically. The profusion of explanations is a testimony to the complexity of this phenomena. This manuscript provides yet another compelling perspective. Cross [(1995) The psychology of Nigrescence: revising the Cross Model, in: J.G. PONTEROTTO et al. (Eds) Handbook of Multicultural Counseling (Thousand Oaks, CA, Sage)] outlines the metamorphic …
