Distributed Enterprises

Abstract Distributed enterprises are now collaborating closely with their suppliers and partners worldwide while continuously improving their response time to global markets. Such distributed enterprises demand greater levels of support for information sharing and collaborative workspaces among engineering development teams. While the use of Intranets for gathering and sharing information is expanding, the organization of the shared information is usually ad-hoc and is not designed to efficiently serve the diverse information needs of work-groups. Such ad-hoc organizations of information result information overload and hence information users have to resort to (syntactic) keyword search to access information. This paper proposes an Information Projection methodology that integrates the organization of the semantic content of shared information with the organization of syntactic content of documents in a way that is meaningful to specific work-groups so as to reduce information overload. The Information Projection methodology has been applied in three different engineering contexts to varied degrees of sophistication and has shown a significant degree of re-usability, although the information and document models that result are themselves very context specific. The information maps resulting from the context of a MEMS technology development project have also been implemented using basic Web technology (HTML, CGI scripts) and has provided several insights on the implications and limitations of such implementations.

The blockchain-based management system has been regarded as a novel way to improve the efficiency and safety of Vehicular Ad Hoc Networks (VANETs). A blockchain-based scheme’s performance depends on blockchain nodes’ computing power composed from the road-side unit (RSU). However, the throughput of blockchain-based application in VANETs is limited by the network bandwidth. A single blockchain cannot record large-scale VANETs’ data. In this paper, we design an atomic cross-chain swap-based management system (ACSMS) to boost the scalability of blockchain-based application in VANETs. The blockchain-based public-key encryption with keyword search is further introduced to protect user privacy. The analysis shows that ACSMS achieves cross-chain swap without loss of CAV security privacy. The simulation results show that our method can realize multiple blockchain-based applications in VANETs.

Zusammenfassung. Hintergrund: Die COVID-19-Pandemie ist eine Ausnahmesituation ohne Präzedenz und erforderte zahlreiche Ad-hoc-Anpassungen in den Strukturen und Prozessen der akutstationären Versorgung. Ziel: Ziel war es zu untersuchen, wie aus Sicht von Führungspersonen und Hygienefachkräften in der Pflege die stationäre Akutversorgung durch die Pandemiesituation beeinflusst wurde und welche Implikationen sich daraus für die Zukunft ergeben. Methoden: Qualitative Studie bestehend aus semistrukturierten Interviews mit fünf Verantwortlichen des leitenden Pflegemanagements und drei Hygienefachkräften in vier Krankenhäusern in Deutschland. Die Interviews wurden mittels qualitativer Inhaltsanalyse ausgewertet. Ergebnisse: Die Befragten beschrieben den auf die prioritäre Versorgung von COVID-19-Fällen hin umstrukturierten Klinikalltag. Herausforderungen waren Unsicherheit und Angst bei den Mitarbeiter_innen, relative Ressourcenknappheit von Material und Personal und die schnelle Umsetzung neuer Anforderungen an die Versorgungleistung. Dem wurde durch gezielte Kommunikation und Information, massive Anstrengungen zur Sicherung der Ressourcen und koordinierte Steuerung aller Prozesse durch bereichsübergreifende, interprofessionelle Task Forces begegnet. Schlussfolgerungen: Die in der COVID-19-Pandemie vorgenommenen Anpassungen zeigen Entwicklungspotenziale für die zukünftige Routineversorgung auf, z. B. könnten neue Arbeits- und Skill Mix-Modelle aufgegriffen werden. Für die Konkretisierung praktischer Implikationen sind vertiefende Analysen der Daten mit zeitlichem Abstand erforderlich.

Zusammenfassung. Der FEO, der in Kooperation mit betrieblichen Praktikern entwickelt wurde, dient der Erfassung des Organisationsklimas. Er umfasst 82 Items und bildet 12 Skalen ab. Eine Stärke des FEO im Gegensatz zu ad hoc entwickelten Befragungsinstrumenten sind die Vergleichsdaten, die für Profit- und Non-Profit-Organisationen bereit gestellt werden. Kritisch diskutiert wird die theoretische Verortung, die Anwenderfreundlichkeit sowie der Nutzen der individuellen Auswertung. Die konsensuale, konvergente, diskriminante und kriterienbezogene Validierung steht aus.

Summary: The two main sources of errors in educational and psychological evaluation are the lack of adequate technical and psychometric characteristics of the tests, and especially the failure to properly implement the testing process. The main goal of the present research is to study the situation of test construction and test use in the Spanish-speaking (Spain and Latin American countries) and Portuguese-speaking (Portugal and Brazil) countries. The data were collected using a questionnaire constructed by the European Federation of Professional Psychologists Association (EFPPA) Task Force on Tests and Testing, under the direction of D. Bartram . In addition to the questionnaire, other ad hoc data were also gathered. Four main areas of psychological testing were investigated: Educational, Clinical, Forensic and Work. Key persons were identified in each country in order to provide reliable information. The main results are presented, and some measures that could be taken in order to improve the current testing practices in the countries surveyed are discussed. As most of the tests used in these countries were originally developed in other cultures, a problem that appears to be especially relevant is the translation and adaptation of tests.
