The decline of Magan and the rise of Dilmun: Umm an-Nar ceramics from the burial mounds of Bahrain, c.2250–2000 BC

This article outlines some general aspects of the Magan and Dilmun trade and goes on to examine the Umm an-Nar pottery discovered in the tombs of the Early Dilmun burial mounds of Bahrain. These ceramics are of particular interest because they indirectly testify to Dilmun's contact with Magan in the late third millennium. In this article, thirty vessels of seven morphological types are singled out. By comparison with the material published from the Oman peninsula the Bahrain collection is tentatively dated to c. 2250–2000 BC. The location of the Umm an-Nar pottery within the distribution of burial mounds reveals that its import was strongly associated with the scattered mounds of Early Type. It is demonstrated that the frequency of Umm an-Nar pottery declined just as the ten compact cemeteries emerged c. 2050 BC. The observed patterns are seen as a response to the decline of Magan and the rise of Dilmun.     

Characterization of dyes in ancient textiles from Yingpan,Xinjiang

In this paper we analyzed the natural dyes in well-preserved, ancient textiles from Yingpan, an important archaeological site on the Silk Road, using high-performance liquid chromatography with diode array and mass spectrometric detection. Dyes were removed from textile fibers using a soft extraction method (pyridine, water and oxalic acid). Two species of madder-type plants, Rubia tinctorum and Rubia cordifolia were identified as the dye sources in red and brown samples. We also were able to detect unusual flavonoid glycosides in yellow and green woolen yarns, although we have not been able to pinpoint with certainty a specific plant that may have been used to produce this dye(s). On the other hand, we found that yellow and green silk threads had been colored with protoberberine-type dyes, probably obtained from species of cork tree, Phellodendron spp., and/or other protoberberine producing plant. We propose that the textile dyes found at Yingpan reflect a merging of Eastern and Western practices and technologies during the 800-year period (206 BCE–618 CE) encompassing the early years of the Silk Road.     

Romantischer Dilettantismus — Johann Wilhelm Ritter und die Begründung der Elektrochemie

In this paper the psychological and historical problems of the german philosophy of nature at the time about 1800 are described. During this time the romantic philosopher and scientist of nature Ritter developed a new scientific branch of knowledge: the electrochemistry. Ritter represents exemplarily the type of a romantic dilettante. In this period, the problem of dilettantism got a new validity, especially by Goethe and Schiller: it was recognized as a positive power of human. In the romantic dilettantism of Ritter three aspects are shown: 1st, romantic dilettantes are intellectual flaneurs; 2nd, romantic dilettantes confront facts and general provisions, which up to this moment are supposed to be paradox, and obtain by this method a synthesis; 3rd, romantic dilettantes favour the intuitive power.     

Is Morality Policy Different? Testing Sectoral and Institutional Explanations of Policy Change

We analyze morality policy change from the perspective of punctuated equilibrium theory (PET) to test whether reform dynamics in this policy sector follow a distinct pattern. First, we propose a new measurement scheme capturing changes in the intensity of morality policy output. Second, we demonstrate that morality policy change is strongly punctuated. Finally, and most importantly, we show that the degree of policy punctuations varies between different domains of morality policy, but not according to institutional features operating on the country level, supporting existing PET research, which has discovered similar domain‐specific dynamics in changes of public spending. Specifically, punctuations are particularly pronounced in areas of manifest morality policy, that is, policies characterized by strong value conflicts, whereas punctuations are less pronounced for latent morality policies, that is, policies in which other dimensions of conflict are present next to the value dimension. Significant differences in reform dynamics are neither discerned for countries belonging to the religious or the secular world, nor for countries with majoritarian or consensual democracies. The analysis relies on an original dataset capturing legislative changes in five manifest (abortion, euthanasia, prostitution, pornography, and homosexuality), and three latent morality policies (drugs, gambling, and handguns) in 19 European countries (1960–2010).
