E-mail in government: Not post-bureaucratic but late-bureaucratic organizations

Empirical research provides evidence that electronic communication does not change government agencies into post-bureaucratic organizations. Structuration Theory is used to explore the interaction between e-mail use, communication patterns of civil servants, and two bureaucratic characteristics: formalization and hierarchy. Previous research suggested that the use of e-mail leads to less formalization and less hierarchy, but empirical research in three bureaucratic organizations in the Netherlands leads to different conclusions. First, the use of e-mail leads to informal formalization: the style of communication is more informal but the content focuses less on personal issues and emphasizes efficient recordings of agreements. Second, the use of e-mail leads to hierarchical horizontalization: horizontal contacts take a more central position in bureaucratic organizations but these horizontal contacts are tightly linked to vertical structures. The result of the interaction between e-mail and government bureaucracy is horizontal communication directly linked to vertical structures. Electronic communication turns government agencies into late-bureaucratic organizations.     

UnCover on the Web: search hints and applications in library environments

Among the huge maze of resources available on the Internet, UnCoverWeb stands out as a valuable tool for medical libraries. This up-to-date, free-access, multidisciplinary database of periodical references is searched through an easy-to-learn graphical user interface that is a welcome improvement over the telnet version. This article reviews the basic and advanced search techniques for UnCoverWeb, as well as providing information on the document delivery functions and table of contents alerting service called Reveal. UnCover's currency is evaluated and compared with other current awareness resources. System deficiencies are discussed, with the conclusion that although UnCoverWeb lacks the sophisticated features of many commercial database search services, it is nonetheless a useful addition to the repertoire of information sources available in a library.     

Forschungs- und Entwicklungsprojekte

Zusammenfassung. Information ist der wichtigste Grundbegriff der Informatik. Ein semantischer Ansatz erklärt Information als Bedeutung einer Nachricht für ihren Empfänger. Als Folge davon hängt der Informationsgehalt einer Datei, einer Datenbank, eines Buches oder eines Filmes von der Interpretation ab, die ein Nutzer vornehmen kann oder gerade vornimmt. Informationsmaße werden sowohl von der Lesbarkeit einer Nachricht als auch von der Qualität des Interpreten bestimmt. Information kann neu entstehen, verloren gehen oder verändert werden.CR Subject Classification: E.4, H.1     

The Motivations of Book Publishers in Germany and Australia: An Empirical Comparison

Our study compares the motivations of Australian and German book publishers. The results demonstrate remarkable similarities, but also a significant difference regarding the effects of the publishers’ self-concept. In the German case the publishers with a dominant economic orientation are more proactive than the publishers with a dominant cultural orientation. In the Australian case, this correlation does not exist. The same difference holds for the relationship between the economic orientation and extrinsic motivation. We discuss these results and examine empirical evidence and theoretical suggestions to explain the differing findings. The data stem from surveys conducted in the two countries with responses of 196 (Germany) and 54 publishers (Australia).     

Predictive value of ventilatory inflection points determined under field conditions

The aim of this study was to evaluate the predictive potential provided by two ventilatory inflection points (VIP₁ and VIP₂) examined in field without using gas analysis systems and uncomfortable facemasks. A calibrated respiratory inductance plethysmograph (RIP) and a computerised routine were utilised, respectively, to derive ventilation and to detect VIP₁ and VIP₂ during a standardised field ramp test on a 400 m running track on 81 participants. In addition, average running speed of a competitive 1000 m run (S_1k) was observed as criterion. The predictive value of running speed at VIP₁ (S_VIP1) and the speed range between VIP₁ and VIP₂ in relation to VIP₂ (VIP_SPAN) was analysed via regression analysis. VIP_SPAN rather than running speed at VIP₂ (S_VIP2) was operationalised as a predictor to consider the covariance between S_VIP1 and S_VIP2. S_VIP1 and VIP_SPAN, respectively, provided 58.9% and 22.9% of explained variance in regard to S_1k. Considering covariance, the timing of two ventilatory inflection points provides predictive value in regard to a competitive 1000 m run. This is the first study to apply computerised detection of ventilatory inflection points in a field setting independent on measurements of the respiratory gas exchange and without using any facemasks.
