Despite the promises made by molecular evolutionists since the early 1960s that phylogenies would be readily reconstructed using molecular data, the construction of molecular phylogenies has both retained many methodological problems of the past and brought up new ones of considerable epistemic relevance. The field is driven not only by changes in knowledge about the processes of molecular evolution, but also by an ever-present methodological anxiety manifested in the constant search for an increased objectivity—or in its converse, the avoidance of (...) subjectivity.This paper offers an exhaustive account of the methodological and conceptual difficulties embedded in each of the steps required to elaborate molecular phytogenies. The authors adopt a historical perspective on the field in order to follow the development of practices that seek to increase the objectivity of their methods and representations. These include the adoption and development of explicit criteria for evaluation of evidence, and of procedures associated with methods of statistical inference, quantification and automation. All these are linked to an increasing use of computers in research since the mid 1960s. We will show that the practices of objectivity described are highly dependent on the problems and tools of molecular phylogenetics. (shrink)

Das hier angezeigte Buch stellt sich dar als eine repräsentative Studie zur byzantinischen Buchkunst über einen Zeitraum von mehr als anderthalb Jahrtausenden. In einem knappen Vorwort reiht Peter Schreiner es in eine bedeutende Forschungstradition ein und zugleich in die Abfolge einer „unübersehbar gewordenen Literatur“. Dabei wird zu Recht hervorgehoben, daß im Unterschied zu vielen anderen Veröffentlichungen des Faches die Buchkunst aus dem slawisch-orthodoxen Bereich voll einbezogen wird, an dessen Erforschung die Verf. mit zahlreichen Arbeiten beteiligt ist. Sie stellt in ihrer (...) eigenen Einleitung dem Leser das vorwiegend liturgische Buch als wesentliches Fundament der byzantinischen Kultur vor Augen. Skizzenhaft erläutert sie seine religiös bestimmte Würde, aus der sich zugleich seine Zierate und Illustrationen rechtfertigen. Es ist einer der Vorzüge der Darstellung, daß dem politischen und kulturellen Zentrum des Reiches Provinzen und Nachbarländer mit vollem Gewicht an die Seite treten: – Syrien, das koptische Ägypten und Äthiopien, Armenien und Georgien, Bulgarien, Rumänien, die Walachei und nicht zuletzt Rußland.

Experimental Essays on Zhuangzi is a classic in the field. Originally published in 1983, this edition makes it available again in an expanded version, with four additional contributions, and in an updated format, with pinyin transcription, Chinese characters embedded in the text, and reference style notes. The work is a well respected textbook and essential reader in Daoist thought. It continues to constitute an essential contribution to the study of Daoism and Chinese philosophy.

Chicks reared in the absence of light and rat pups reared without extra stimulation fail to exhibit behavioral laterality, implying that a threshold amount of environmental stimulation is necessary for the brain to follow an asymmetry pathway. Reverse asymmetry has been reported in the chick, but not the rat, though a sex difference resembling reverse asymmetry has been found in the rat.
