Reine und angewandte Chemie Die Entstehung einer neuen Wissenschaftskonzeption in der Chemie der Aufklärung

In its attempt to achieve acknowledgement and support as a true science and academic discipline eighteenth-century chemistry experienced that the traditional distinction between theory and practice, respectively between science and art, was an incriminating heritage and did not longer conform to the way chemists saw themselves. In order to substitute the former, socially judging classification into theoretical science and practical art, J. G. Wallerius from Uppsala coined the term pure and applied chemistry in 1751. The idea behind this new conception was that it ought to be chemistry's research aim and not the kind of work, be it manual or intellectual, which was to decide about its branches and their dignity. The change in orientation which took place during the eighteenth century, and which is symbolized by the new dichotomy “pure and applied”, led towards a revaluation of the utilitarian aspects of chemistry. Its historical roots reach back to a long and fruitful cooperation of, and interaction between chemistry and economy, which was reinforced by the Stahlian tradition in Germany and Scandinavia. Subsequently, it was its strong economic bias that helped chemistry to become institutionalized and accepted as an academic discipline distinct from the medico-pharmaceutical profession. The analysis of this change of attitudes, behaviour and institutional pattern suggests that, at least during the period of institutionalization of this particular discipline, social structures and the intrinsic scientific contents are so tightly interrelated, that any division into “internal”, cognitive developments (facts, theory and subject-matter) and “external” conditions (social context and stategies of institutionalization) would be artificial, since they both constitute the scientific community as a context of argumentation and action.     

Living in anachronistic space: Temporalities of displacement in Moscow's Soviet-era standardised housing

In 2017, the Moscow municipality announced the demolition of several thousand remaining Soviet-era, standardised apartments (khrushchevki). Known as the Renovation, the renewal project promises to replace the khrushchevki with new residential districts. Based on fieldwork in Northern Izmailovo, a district targeted for demolition, this article analyses encroaching displacement by foregrounding the temporal experiences of affected residents. Building on literature that explores the political underpinnings of discourse and aesthetics in urban renewal projects, with particular attention to Rancière's temporal politics, the article contends that the Renovation depends on the discursive construction of its targets as spatial anachronisms. This renders the Soviet-era housing blocks, and those who live within them, vulnerable to a spectrum of modernising aestheticising interventions—from minor ornamentation to wholesale demolition. Based on ethnographic data, the article shows how the initial stages of redevelopment have altered a local network of benches. For a group of long-standing, elderly residents, these disruptions have instigated more profound reckonings with their own sense of time in/and space, leading to an understanding that they, too, are seen as anachronistic features of the city. Paying attention to urban materiality on a granular scale, particularly in standardised housing estates, reveals the multifaceted temporalities that inform residents' engagements with the spaces of their home districts. The article argues that doing so counters the exclusionary temporal logic of the discourse of anachronism by denying its ubiquity. In turn, it speaks to growing geographic interest in amplifying alternative temporalities in the face of destructive, terminal change.     

Natur-Wissenschaft und Gotteserkenntnis: Das jüdische Modell

The thesis proposed here is that in Judaism creation is seen as a unique act of God at a specific point in time. In medieval philosophy the act of creation is interpreted as natural science, which concerns itself only with products of divine creation. This is contrasted with theology, which is concerned not with creation but with God. Francis Bacon takes this model from Moses Maimonides for his work Nova Atlantis. Natural science replaces theological studies for Bacon.     

HISPANO-MORESQUE POTTERY PRODUCTION OF THE FOURTEENTH-CENTURY WORKSHOP OF TESTAR DEL MOLÍ (PATERNA,SPAIN)

Excavation of Testar del Molí, the only workshop found in the Manises-Paterna area, revealed the existence of a fourteenth-century ceramic workshop covering the remains of the thirteenth-century workshop. This study is concerned with the fourteenth-century production, and forthcoming papers will connect both epochs following the findings of current excavations. The chemical and mineralogical characterization of the ceramic production of this workshop shows the presence of three groups of ceramic pastes which could also be distinguished by, and, thus, related to, their daily use. The raw materials found in the excavation have also been mineralogically and chemically characterized, and a model of possible mixtures of raw materials has also been developed in order to determine their possible use in the manufacture of the pottery previously characterized.     

TECHNOLOGY AND COLOUR DEVELOPMENT OF HISPANO-MORESQUE LEAD-GLAZED POTTERY

Lead-glazed pottery from the medieval workshop of Les Olleries Majors (Paterna, Spain) has been studied by Mössbauer spectroscopy, X-ray diffraction, X-ray fluorescence and optical spectroscopy. Yellow, brown and honey-coloured glazes occur on pots glazed on only one surface. They have virtually identical compositions and transmittance spectra, their apparent differences in colour are due to the colours of the underlying pastes. Yellow glazes occur on cream-coloured calcareous bodies, honey-coloured glazes occur on less calcareous bodies with some development of hematite, while brown glazes occur on red siliceous cooking-pots. Green glazes are found on pots glazed on both surfaces; the glazes trapped CO₂ evolved by decomposing carbonates, resulting in an internal reducing environment. This caused the reduction of iron to the ferrous state which coloured the glaze green by diffusion.     

King Davidʼs Exposure while Dancing: A Queer Reading of 2 Samuel 6

According to the Hebrew version of the transport of the ark to Jerusalem in 2 Samuel 6, King David is so scantily dressed that he publicly exposes himself while dancing before G*d (????). David?s wild, gay and possibly sexual conduct can evoke associations with the behavior of gay persons of today. Queer readers may identify with David and like him turn their backs on dominant rulers—like the members of Saul?s dynasty—if they are not respected because of their queer way of life, but persecuted—as David was persecuted by King Saul. Such an interpretation implies that G*d (????) is on the side of persons like King David, who—from the point of view of other people as well as of David?s wife Michal—behave in a strange fashion, thus act queerly.     

Studying Immigrant Policy One Law at a Time

This article shows that, in the study of immigrant integration policy in the U.S. states, it is critical to report data and coding decisions for individual laws. This analysis uses an updated and public database of law‐level decisions, which includes 2,703 legislative actions recorded by the National Conference of State Legislatures from 2005 to 2016. These data are used to estimate models of aggregate state policy activity in a variety of ways: as a single continuum of policy balance versus separate models of welcoming and hostile, lumping all policy subareas together versus analyzing a specific subarea, and lumping all years together in one cross section versus panel analysis. The results in these models differ enough to indicate that reporting codes for individual‐level laws is absolutely essential so that each researcher easily can construct the measure that fits his or her theoretical framework best.
