Patterns of Internet and Traditional News Media Use in a Networked Community

Abstract

International communication has come increasingly under the impact of at least three major technological, socio‐economic, and political forces: expanded channels of communication provided by technological developments, democratizing pressures that have brought new voices to be heard in international media and forums, and new but as yet weak mechanisms for the conduct of meaningful dialogue and negotiations. Power politics has been thus increasingly supplemented or supplanted by image politics, questioning traditional boundaries between domestic and international politics, and creating image fixations that have proved occasionally inimical to accommodation of real interests. The symbolic uses of images, on the other hand, have served at least three kinds of cognitive interests: national solidarity, and domestic instrumental and global community. The Iranian hostage crisis, among a number of other contemporary examples, illustrates how these interests were served, symbolically and actually, in domestic as well as international politics. Through a case study of the hostage crisis, me paper concludes with some warnings on the potentials as well as menaces of image politics.     

“What a Relief”: When the Press Prefers Celebration to Scandal

Performing the citizen's role in an enlightened manner requires information and interpretation that are not dependent on government sources. Therefore, the major role assigned to the press by democratic theory is to provide such alternative views of reality. This task becomes particularly difficult in what is defined as a security crisis, where journalists must decide on giving voice to the establishment in the national interest; satisfying the public, which may prefer not to know; or providing oppositional readings. Analysis of television and press coverage of a failed terrorist attack on an Israeli beach shows how evidence of chaos and sheer luck can be discerned in a narrative of ostensible planning and purposiveness. Five framing mechanisms are deconstructed: prioritizing the army's version of the event; moving the spotlight from the tactical to the strategic; ignoring the critical potential of naive witnesses, who authenticate hegemonic framing; resorting to the myth of existential danger to Israel; and turning a miracle for the army into a miracle for the lews.     

Visualisation of fingermarks and grab impressions on dark fabrics using silver vacuum metal deposition

Vacuum metal deposition (VMD) involves the thermal evaporation of metal (silver) in a vacuum, resulting in a uniform layer being deposited on the specimen being treated. This paper examines the use of silver on dark fabrics, thus offering a simpler operation and more obvious colouration to that of the traditional use of gold and zinc metals which must be evaporated separately. The aim of this study was to investigate the effect of fabric type, donor, mark age and method of fingermark deposition on the quality of marks visualised using silver VMD. This was achieved by collecting fingermark deposits from fifteen donors, of both sexes and various ages, by a grab or a press method. Four different fabrics: satin, polyester, polycotton and cotton were studied over a 10 day timeline of 1, 2, 3, 4, 5, 6, 7, 14, 21 and 28 + days. It was found that satin and polyester gave the most positive results, with polyester often producing excellent ridge detail. Cotton and polycotton were less successful with no ridge detail being observed. The donors also had an observable effect on the results obtained probably due to variations in secretions produced or pressures applied during specimen collection. The age of the mark or the method of mark deposition had little influence on the results obtained. Silver VMD is a viable process for visualising marks on certain dark fabrics and has the advantage over gold/zinc VMD in that the marks visualised are light in colour which contrasts well against the dark background.
