Chronotypologie und Schichtarbeit : Möglichkeiten und Potential der individuellen Berücksichtigung unterschiedlicher Chronotypen im Rahmen betrieblicher Gesundheitsförderung

Die aus Schichtarbeit resultierende Verschiebung der zeitlichen Lage von Arbeit und Schlaf führt zu einer Belastung für den menschlichen Organismus. Inwieweit diese Belastung für ein Individuum zur Beanspruchung wird, ist neben anderen Faktoren auch vom Ausmaß dieser Verschiebung abhängig. Die individuelle Zeitstruktur eines Menschen findet dabei Ausdruck in seinem Chronotypus (ugs. "Eulen" und "Lerchen"). Ziel dieser Arbeit ist es, zu ermitteln, inwieweit eine betriebliche Berücksichtigung individueller Chronotypen bei Schichtarbeitenden zu deren Gesunderhaltung beitragen kann. Hierfür wurde eine systematische Literaturrecherche für den Zeitraum 2000 bis 2013 durchgeführt. Es kann aufgezeigt werden, dass die Belastung der Schichtarbeit nicht für alle Chronotypen identisch ist. Vielmehr ist die Adaptionsfähigkeit an konkret zu leistende Schichten, z.B. eine Nachtschicht, vom Chronotyp abhängig. Aus dem Zusammenhang zwischen Chronotyp, Schicht und Schlaf resultiert die Empfehlung einer zukünftigen Berücksichtigung in der Gestaltung von Schichtplänen. Eine engmaschige arbeitsmedizinische Begleitung extremer Chronotypen und die individuelle Schlafberatungen aller Früh- und Spättypen sind zusätzlich angeratene Maßnahmen betrieblicher Gesundheitsförderung mit vermutlich kurzfristiger Wirksamkeit.

Morphometric and genetic differentiation among populations of Eupemphix nattereri (Amphibia, Anura, Leiuperidae) from central Brazil

To assess genetic structure and phenotypic diversity of Eupemphix nattereri Steindachner, 1863, morphometric and molecular analyses were carried out for nine populations from the State of Goiás. A total of 11 morphometric traits were evaluated and genetic information was estimated using RAPD markers. Genetic and phenotypic distances were determined as a function of geographical origin. Correlation among genetic, morphometric, micro, and macroenviromental were analyzed by the Mantel test. Genetic data indicated high levels of genetic diversity (Φst= 0.3) among the nine populations. Mantel tests did not reveal a significant positive correlation between genetic and geographical distances, indicating that locally geographical populations were not genetically similar, even in distances smaller than 50 km. Discriminant analysis on 11 morphometric measurements showed a high divergence among the nine populations. However, a marginally significant correlation (P=0.08) between genetic and morphometric distances was found. The observed correlation was not causal in terms of the relationship between phenotype and genotype, but indicated common spatial structures. Thus, our results suggest that isolation-by-distance processes may explain population divergence in Eupemphix nattereri.

Occurrence of Cabassous tatouay (Cingulata, Dasypodidae) in Rio Grande do Sul and its potential distribution in southern Brazil

ABSTRACT Cabossous tatouay Desmarest, 1804 is considered a rare species in southern South America, and Rio Grande do Sul State, Brazil, records of the species are scarce and inaccurate. This study reports 40 localities for C. tatouay, and provides a map of the species' potential distribution using ecological niche modeling (ENM). The ENM indicated that in this region C. tatouay is associated with open grasslands, including the areas of "Pampas" and the open fields in the highlands of the Atlantic Forest. This study contributes to the information about the greater naked-tailed armadillo in southern Brazil, and provides data key to its future conservation.

The Experience of European Integration and the Potential for Integration in South America

The experience of the European Union is the most significant and far-reaching among all attempts at regional integration. It is, therefore, the most likely to provide some lessons for those world regions that are just beginning this complex process. In turn, the Common Market of the South (MERCOSUR) and the Andean Community (CAN) are among the regional integration projects that have reached the greatest level of formal accomplishment after the EU. MERCOSUR is a customs union that aspires to become a common market, while avowing the commitment to advance towards political integration. For its part, CAN is a customs union that has already developed supranational institutions such as a Commission, a Parliament and a Court of Justice. In both cases, however, words have progressively tended to wander far from deeds. One reason underlying this phenomenon may be a misunderstanding of the European experience with integration. In this article, we discuss the theories that have been developed to account for integration in Europe and may prove useful to understand integration elsewhere and put forward a set of lessons that could be drawn from the European experience. Subsequently, we introduce a description of the experience of integration in South America and reflect (critically) on how the theories and lessons drawn from the EU could be applied to this region –and beyond.
