Aufschwung am Arbeitsmarkt: Trendwende oder Strohfeuer?

Im aktuellen Aufschwung hat auch die Arbeitslosigkeit deutlich abgenommen. War die Beschäftigungsintensität des Wachstums im Aufschwung 1998-2000 größer? Welche Bedeutung kommt den Reformen auf dem Arbeitsmarkt für den derzeitigen Aufschwung zu? Wird der Rückgang der Arbeitslosigkeit aufgrund einer Statistikbereinigung überzeichnet? Ist der gegenwärtige Aufschwung konjunkturell oder strukturell bedingt? --

Immunity status against poliomyelitis in Germany: Determination of cut-off values in International Units

Background: To prevent importations of wild polioviruses into a polio free region a high level of population immunity must be kept. Standard methodology for determination of polio antibodies is a feature aimed at obtaining consistent results. An International Standard Serum for polio antibodies exists, but no protective level in International Units is defined. Methods: A representative study was carried out in order to determine the serological status against poliomyelitis in Germany (n = 2564, age 18–79 years). Furthermore, sera from persons aged less than 18 years were included (n = 881). Microneutralization test has been used for determination of antibody levels. Results have been expressed in International Units. Results: The results of this study indicate that the cut-off level for polio antibodies is 0.075 IU/ml for Polio 1, 0.180 IU/ml for Polio 2 and 0.080 IU/ml for Polio 3. Neutralizing antibodies against poliovirus type 1, 2 and 3 were detected in 96.2%, 96.8% and 89.6% of samples, respectively. Conclusions: Overall, this seroprevalence indicates a very high level of immunity of the general population. It must be kept after the switch of immunization strategy from attenuated to inactivated vaccine in Germany

Konzeption und Realisierung eines computergestützten Besucherinformationssystems für die Stadtbücherei Stuttgart

Gegenstand der hier vorliegenden Arbeit ist es, ein computergestütztes Besucherorientierungs- und Informationssystem für die Stadtbücherei Stuttgart zu planen und in die Praxis umzusetzen. Der konzeptionelle Teil behandelt die Fragen, welche Informationen in dem System angeboten und auf welche Art und Weise sie dem Betrachter präsentiert werden sollen. Hierbei ist die Einsatzsituation des Systems durch das Kapitel zum Zusammenspiel mit dem konventionellen Leitsystem und das Kapitel zur weiteren Pflege des Besucherinformationssystems berücksichtigt. Die Umsetzung des Konzeptes mit der Animationssoftware Macromedia Flash wird sowohl von der planerischen als auch von der technischen Seite her erläutert, das fertige Produkt findet sich auf der beiliegenden CD-ROM als Teil dieser Arbeit. Zum Abschluss geht die Arbeit kurz darauf ein, wie andere Bibliotheken das in dieser Diplomarbeit entworfene Konzept auf ihre Situation übertragen können. Erweiterungsmöglichkeiten des Konzeptes werden ebenfalls aufgezeigt

Socioeconomic inequalities in cancer incidence and mortality - a spatial analysis in Bremen, Germany

Aim: Several international studies have already investigated the influence of socioeconomic factors on the risk of cancer. For Germany, however, the data are still insufficient. We examined the effects of social differences on cancer incidence and mortality on the population of Bremen, a town in northwest Germany. Subjects and methods: Data were obtained from the Bremen Cancer Registry, a population-based registry. The database comprised 27,430 incident cases, newly diagnosed between 2000 and 2006. The allocation of social class for each patient was based on the home address at the time of diagnosis, which led to the corresponding town district, which again could be linked to the “Bremen discrimination index.” Based on this index, cases were allocated to five categories, for which we compared standardized incidence ratios (SIR) and mortality ratios (SMR) for different cancers: prostate, breast, lung, colorectal, bladder, uterine, ovarian, cervical, malignant melanoma of the skin, non-melanoma skin cancer and all cancer sites summarized. Results: The influence of social status was observed for different cancer sites. An inverse association was ascertained for all cancer sites (only men) and for tumors of the oral cavity and pharynx, and for lung, cervical and bladder cancers. A positive correlation was observed for female breast cancer, malignant melanoma, non-melanoma skin tumors and prostate cancer. Conclusions: In spite of the methodical restrictions, our analyses suggest an association between social factors and cancer incidence and mortality. The results are in agreement with international studies. Many of the observed social class differences could probably be explained by known risk factors, such as smoking, alcohol consumption, diet and physical activity

Maximal coherence and the resource theory of purity

The resource theory of quantum coherence studies the off-diagonal elements of a density matrix in a distinguished basis, whereas the resource theory of purity studies all deviations from the maximally mixed state. We establish a direct connection between the two resource theories, by identifying purity as the maximal coherence which is achievable by unitary operations. The states that saturate this maximum identify a universal family of maximally coherent mixed states. These states are optimal resources under maximally incoherent operations, and thus independent of the way coherence is quantified. For all distance-based coherence quantifiers the maximal coherence can be evaluated exactly, and is shown to coincide with the corresponding distance-based purity quantifier. We further show that purity bounds the maximal amount of entanglement and discord that can be generated by unitary operations, thus demonstrating that purity is the most elementary resource for quantum information processing
