SAE应做好路径选择

随着全球通信技术的快速发展，移动通信技术已经进入了3GHx）代，各种通信新技术层出不穷，面对各种新技术的挑战，3GPP想要保持自己在未来移动通信领域的技术先进性，就必须持续不断地提高自己的竞争力。针对未来无线接入网侧的演进，3GPP启动了长期演进计划（LTE，Long Term Evolution）。同时，为了适应无线接入网测的演进，3GPP认为核心网侧也有必要持续演进和增强，于是也开始进行系统架构方面的演进研究——系统架构演进（SAE）。     

2004年3G在中国的几大看点

即使2004年中国3G牌照谜局悬而未决，但3G测试结果的公布及电信运营商高层换岗都预示着2004年仍可称得上是一个”准3G年”。3G概念在2004年是被爆炒了一把，但是如果做到产业化还需要较长的一段路要走。下面主要分析2004年3G在中国的几大看点：     

IMS应用的关键问题分析

IMS是在3GPP R5版本提出了一个新的子系统——IP多媒体子系统。IMS是在承载网络的基础上附加的网络，用户通过无线接入网和3G核心网的分组域接入IMS。IMS主要采用SIP协议，可以向用户提供综合的话音、数据和多媒体业务，它和电路域相对独立，并可以实现互通。3GPP在R6和R7版本对IMS进行了完善和扩展。

Die Absolventenbefragung als Methode der Lehrevaluation in der Kommunikationswissenschaft

Surveys among alumni are a common but hardly reflected method of evaluating teaching in communication departments. In light of the increasing significance of evaluation at the universities and the high competition on the job market, it seems advisable to look at this instrument more closely. An advantage of alumni surveys is that they allow to compare directly people’s studies and the requirements of the jobs people hold. In a meta-analysis,19 alumni surveys conducted in German-speaking countries between 1995 and 2004 were reviewed. Differences between the studies at different universities make ex post facto comparisons more difficult. Results show: Graduates from complete journalism programs find jobs especially quickly. In general, practical experience is the most important factor in finding a job. Most respondents would chose their field of studies again if they were given a chance. Future alumni surveys should be coordinated to allow for better comparison and for collecting data representative of the field.     

Das Paradox der Medienwirkung auf Nichtnutzer

The article presents data from a secondary analysis of the project »Wählerwanderungen und Politikverdrossenheit« from 1994. The data allow to conduct time series analysis on a day-to-day basis. The focus is agenda setting in combination with a thesis formulated by Marcus Maurer — published in Publizistik 2004 — on the paradox of media effects on non-users. In contrast to Maurer, the paper is not concerned with the methodological but the theoretical paradox: Can there be such a thing as media effects on media non-users? The hypothetical effect is analyzed in comparison of daily and less than daily TV news users. The analyzed models confirm the agenda-setting effect: The media agenda affects the public agenda at later points in time, but the public agenda does not have effects on the later media agenda. In addition, there are indirect effects on people who seldom use TV news. As they do not watch every day, there is no direct immediate effect of the media input on them. But there is a significant effect some days later, which we interprete as a consequence of conversation. The effect of the media on the daily users is passed on to less frequent users by interpersonal communication.     

Qualität auf dem Anzeigenmarkt und ihre publizistischen Implikationen

In the field of communication and journalism, an old subject is revived: the criticism of advertisers’ influence on the content of print media. The assumption of such an influence — first claimed in articles by Karl Bücher from the twenties — is supported by hinting at the sources for publishers’ revenue, i.e. the dominance of revenue from advertising over that from paper or magazine sales, and also by the tougher competition. A susceptibility of publishing houses to yield to advertisers’ demands also when they concern news or editorial content is deduced from this. As a consequence, the product as traded among a market of readers is formed by the demands on a market of advertisers. This suggests negative consequences for the quality of a paper. At first, this article investigates quality criteria on the advertisers’ market and its interdependence with the readers’ market. Then it evaluates the (potential) consequences of advertisers’ influence on the media product. Finally, it presents an explicatory model of relevant mechanisms.     

Ein Objekt, das sich verweigert: Der Journalismus in der Soziologie Pierre Bourdieus

Gilles Bastin develops a critique of the concept of the »field of journalism» (»champ journalistique«) in the sociology of Pierre Bourdieu. At first, the genesis of the object under scrutiny, journalism, within Bourdieu’s sociology is introduced. Thus the continuity is made clear with which Bourdieu — from the sixties onwards — conceives of journalists as increasingly powerful agents (»opérateurs«) of »social magic« (»magie sociale«) and of processes primarily in the field of intellectuals. Bastin then analyzes the various suggestions made by different authors for describing the »field of journalism«, and he looks at the variance in using this notion, which makes the concept of the field as such very heterogeneous. In light of other conceptions borrowed from the sociology of professions, such as Everett C. Hughes’, he suggests three critical perspectives: First, Bourdieu’s concept of the field makes work »vanish«; it neglects the conditions of working and the substantial activities of journalists. Second, it leads to a disparate view of journalists’ activities as a subject for research. And thirdly, it decidedly individualizes journalists’ activities.     

1987: AIDS erreicht Deutschland

When, and how, was the issue of AIDS first established in the broad population in (West-)Germany? Our case study shows that 〉Bild〈 (the leading national tabloid newspaper) may have played an important part in establishing the issue. The people’s concern about AIDS runs astonishingly parallel with the intensity of coverage in 〉Bild〈. Even priming effects, such as the number of HIV-Tests performed, appear to be inspired by 〉Bild〈. At the same time, it becomes clear that coverage in 〉Bild〈 did not necessarily follow topical events.     

Impact und NormalwissenschaftImpact and normal science

Communication and media studies owe much to our academic journals. At the same time, however, journals increasingly become a space where reputation and careers are negotiated. In so doing, journals move away from their genuinely substantive role as shapers of academic discourse and are increasingly being misused as a political tool to shape science and research. This contribution highlights three particularly toxic issues: (1) the ecological fallacy of inferring individual quality from journal impact, (2) the equation of citations, impact and quality, and (3) the blind use of peer review. The above-mentioned developments have produced a dramatic rise in publication output and a ridiculous arms race for publications. In this race, the generated publication output bears little relation to a healthy gain in knowledge. The increasing importance of academic journals leads to a gradual normalization of the journal article format as “publication standard”. This privileges a specific form of research that lends itself to the publication in journals. Combined with a blind use of peer review, this is a dangerous breeding ground for “normal science” and conceptual stagnation.

Strategic Leadership Communication for Crisis Network Coordination

In large-scale societal crises, organizations involved in saving lives and protecting the public need to collaborate and coordinate their crisis communication to minimize damage and increase resilience. This study analyzed strategic leadership communication fostering such coordination in a network consisting of 24 members representing a variety of authorities, organizations and units established during a large forest fire in Sweden. As the crisis unfolded over a two-week period, 10 network meetings were observed and audio recorded. Discourse analysis was employed to analyze network leaders’ and members’ communication during the meetings. Findings illustrate that leadership communication strategies that fostered networked coordination of organizations’ crisis communication differ in significant ways from leadership communication in noncrisis and team contexts. Salient leadership communication strategies of directing/structuring and encouraging/facilitating were employed during crisis network meetings and functioned to coordinate involved organizations’ crisis communication efforts during time pressure. The study contributes with new knowledge of strategic leadership communication for crisis network coordination, which is important to crisis management and can be used in crisis preparation to enhance resilience.
