Sigmund Freud's Contribution to the History of the Neuronal Cytoskeleton

In the summers of 1879 and 1881, while Freud was a research student in Ernst von Brücke's laboratory at the Institute of Physiology at the University of Vienna, he carried out an important though seldom remembered investigation on the internal structure of nerve fibers and cells. His contribution to this field is here examined in the context of the 19th-century debate regarding the existence of neurofibrils and of present views on the cytoskeleton. Freud was able to discern separate fine fibrils following straight courses within the nerve fibers, as well as concentric loops of striae surrounding the nuclei and converging towards the processes of the cell bodies in crayfish nervous tissue. He thus confirmed and extended observations made by Robert Remak almost 40 years earlier, which had remained controversial. Electron microscopy of the crustacean nervous system confirmed Freud's main points, which in turn vindicated those of Remak. Both researchers were looking at small bundles of microtubules, and thus they were among the first to picture the lacy intracellular framework that future cell biologists would call the cytoskeleton.

“Loyalty” in National Socialism: A contribution to the moral history of the National Socialist period

This article is based on the assumption that core concepts of National Socialism—different from Marxism—turn not on economic, but on moral concepts, or categories heavily related to such concepts as honour, loyalty, decency and comradeship. The article investigates National Socialism from the standpoint of moral judgments, and turns this investigation into part of a moral history. It further is concerned with the continuing impact of National Socialism beyond the military, political and ideological defeat of 1945; the moral historical approach can show how this influence continues at a level hitherto relatively unexamined. The moral history of National Socialism involves more than a shift of perspective. It opens up a specific, barely explored, field of research. This draws upon a variety of sources, especially films (Hotel Sacher—1939 and Downfall—2004 are discussed). The examination is directed to the concept of loyalty within this framework; it is a concept of virtue, which is moreover suited to illuminate some aspects of the functioning of Nazi morality, and its subsequent influence.     

Late Weichselian deglaciation and sea level history of St Jonsfjorden,Spitsbergen: A contribution to ice sheet reconstruction

The elevation and age of surveyed shorelines in St Jonsfjorden, western Spitsbergen, provide a chronology for Late Weichselian deglaciation and a proxy for former ice thickness. Support is provided for previous reports of two sets of shorelines on NW Spitsbergen, the oldest (at 60 m in St Jonsfjorden) dating to a pre‐late Weichselian glaciation and the youngest documenting postglacial rebound. The remarkable survival of the older shorelines suggests that a large area of NW Spitsbergen was either covered by protective, cold‐based ice or was subject to only local glaciation during the late Weichselian even though glacier ice extended to the shelf edge in the Isfjorden Trough. A marine limit of 46 m at the mouth of St Jonsfjorden is compatible with the regional late Weichselian marine limit (LWML) dated to ～13 ka BP. A partial relative sea level curve and equidistant shoreline diagram are produced for St Jonsfjorden and used in conjunction with relative sea level curves based on data from previous studies to produce an isobase map for 9 ka BP. The curves indicate that western sites were subject to initial slow emergence followed by rapid emergence between 10 ka and 8.2 ka BP, trends characteristic of areas affected by a full glacial sea or at least subject to early break up of a thin or discontinuous glacier ice cover. A step in the 9 ka BP shoreline long profile over the western end of the peninsula separating Isfjorden and van Mijenfjorden suggests that Holocene neotectonics may have produced anomalously high rebound rates in that area.     

从环境的历史到环境史——关于环境史研究的一种认识

By and large, there are three kinds of research on environment: the history of environment as a field of natural history studies, the history of environment as within the scope of history of society studies, and environmental history as the study of the relationship between human and nature. The methodological perspective of the relationship between humanity and environmental distinguishes the third from the previous two. From this perspective, when we probe the mutual effects between human and nature, we will stress on their interactions. The new era and the realities of contemporary society foster the rise of environmental history, which has not only theoretical values but also practical significance.
