Critical factors influencing secondary school pupil’s decisions to study computing in tertiary education: Gender differences

This paper aims to determine the factors affecting the decisions of both male and female secondary school pupils whether or not to pursue undergraduate studies in Computing. It is based on research conducted in Greece, on a sample of 248 pupils, 135 of whom were female. All were aged 17 and about to decide on their future undergraduate studies. Questionnaires were used, addressing issues in the following four main categories: a) the reasons pupils chose/rejected Computing, b) how family and friends, the media and the school environment contribute to their decision, c) how pupils perceived their future after studying Computing and d) how pupils perceived the profile of a computer professional in terms of gender.

Qualitätssicherung im österreichischen Hochschulsystem

Die ?sterreichischen Universit?ten und Fachhochschulen sind gesetzlich dazu aufgefordert, interne Qualit?tssicherungsprozesse und -systeme zu entwickeln. Der Grundsatz der Erstverantwortlichkeit der Hochschulen für die Sicherung von Qualit?t in Lehre, Forschung und Organisation tr?gt der Hochschulautonomie Rechnung, und er kommt durch die im Zuge des Bologna-Prozesses vereinbarten Europ?ischen Standards der Qualit?tssicherung zum Ausdruck. Als Qualit?tssicherungsagentur für den gesamten Hochschulbereich in ?sterreich bietet die AQA Universit?ten und Fachhochschulen externe Begleitung, vermittelt unabh?ngige Expertise und führt Evaluierungen durch. Die AQA hat ihre Leistungen und Verfahren auf Grundlage europ?ischer Standards der externen Qualit?tssicherung für Universit?ten und Fachhochschulen entwickelt. Die Verfahren der AQA stellen die hochschulinterne Qualit?tskultur in den Mittelpunkt: Basierend auf den Erfahrungen mit externen Evaluierungsverfahren und des Hochschulvergleichen, welche die AQA seit 2004 durchgeführt hat, implementiert die Agentur nun ein Verfahren, welches das hochschulinterne Qualit?tsmanagement st?rken soll und den Hochschulen l?ngerfristig eine Zertifizierung ihres Qualit?tsmanagements bietet. Die AQA stellt hierfür die Expertise internationaler Expertinnen und Experten zu Themen des Hochschulmanagements bereit und nutzt Kooperationen mit anderen Qualit?tssicherungsagenturen. Auf l?ngere Sicht k?nnte ein prozessorientiertes "Quality Audit"-Verfahren eine Referenz der externen Qualit?tssicherung für den gesamten ?sterreichischen Hochschulbereich darstellen.     

IPv6: The next generation Internet Protocol

IPv4, the workhorse protocol of the currently popular TCP/ IP protocol suite, is fast becoming obsolete. The exponential growth of the Internet is the main reason that has required the creation of the next generation of Internet Protocol-IPv6. IPv6 is much more flexible and promises to take care of the address space and security issues in the foreseeable future. Part 1 of the paper lays the foundation of the various issues involved in designing the Internet Protocol and motivates the need for an upgraded version of this protocol.     

Practical Applications as a Source of Credibility: A Comparison of Three Fields of Dutch Academic Chemistry

In many Western science systems, funding structures increasingly stimulate academic research to contribute to practical applications, but at the same time the rise of bibliometric performance assessments have strengthened the pressure on academics to conduct excellent basic research that can be published in scholarly literature. We analyze the interplay between these two developments in a set of three case studies of fields of chemistry in the Netherlands. First, we describe how the conditions under which academic chemists work have changed since 1975. Second, we investigate whether practical applications have become a source of credibility for individual researchers. Indeed, this turns out to be the case in catalysis, where connecting with industrial applications helps in many steps of the credibility cycle. Practical applications yield much less credibility in environmental chemistry, where application-oriented research agendas help to acquire funding, but not to publish prestigious papers or to earn peer recognition. In biochemistry practical applications hardly help in gaining credibility, as this field is still strongly oriented at fundamental questions. The differences between the fields can be explained by the presence or absence of powerful upstream end-users, who can afford to invest in academic research with promising long term benefits.     

Integrierte Entwicklung von Automotive-Software mit AutoFocus

Zur Beherrschung der komplexen vernetzten und verteilten Funktionen von Automotive-Software ist eine Beschreibung des zu erstellenden Systems auf verschiedenen Abstraktionsebenen und schrittweise überg?nge zwischen diesen Ebenen notwendig. Neben der Definition geeigneter Ebenen werden zur Unterstützung echtzeitkritischer Systemanteile ein einheitliches Berechnungsmodell, ebenenspezifische Beschreibungstechniken, sowie methodische Regeln für diese Abstraktionsebenen eingeführt und in den Werkzeugprototypen AutoFocus integriert.     

Dimensions of variability in embedded operating systems

Design, implementation, and re-engineering of operating systems are still an ambitious undertaking. Despite, or even because, of the long history of theory and practice in this field, adapting existing systems to environments of different conditions and requirements as originally specified or assumed, in terms of functional and/or non-functional respects, is anything but simple. Especially this is true for the embedded systems domain which, on the one hand, calls for highly specialized and application-aware system abstractions and, on the other hand, cares a great deal for easily reusable implementations of these abstractions. The latter aspect becomes more and more important as embedded systems technology is faced with an innovation cycle decreasing in length. Software for embedded systems needs to be designed for variability, and this is in particular true for the operating systems of this domain. The paper discusses dimensions of variability that need to be considered in the development of embedded operating systems and presents approaches that aid construction and maintenance of evolutionary operating systems.
