Competing conventions: The Big Branders’ struggle to incorporate new quality conceptions in the Norwegian food market
No full textThe paper addresses recent changes in the Norwegian agrifood industry from the analytical perspective of quality conventions. Storper and Salais’ “worlds of production” plus Boltanski and Thévenots’ “orders of worth” are used as a basis for the empirical study. First, the paper discusses how the largest Norwegian branders try to strategically adapt to “novel” quality attributes like health-enhancing food, origin/terroir, environmental sustainability and ethics. Second, the paper investigates the companies’ quality signalling strategy: How are these “novel” qualities communicated to consumers? Multiple options are available: Do they attempt to systematically incorporate “novel qualities” into their private brand equity (“conventionalizing qualities”)? Do they prefer a co-labelling scheme with a third party control, or do they use any other measures for quality signalling? The paper thereby discusses how the largest Norwegian branders in the food sector cope with conflicting and competing quality conventions.Food quality, economics of convention., Food Consumption/Nutrition/Food Safety,

The Worldview and the Author´s (Self)Reflection in Czech Contemporary Historiography
No full textCílem studie je představit možnosti, jak na základě publikovaných autorských textů zkoumat světový názor historiků a historiček, zejména v oboru soudobých dějin, kde lze předpokládat vliv jejich hodnotového horizontu na interpretaci relativně nedávné minulosti. Autor nejprve vymezuje pojetí světového názoru vzhledem ke stanovenému záměru a zdůvodňuje analytické užití tohoto pojmu v historiografickém textu, v daném kontextu se také zamýšlí nad vztahem paměti, dějin a historiografie. Konstatuje, že poměrně málo českých historiků a historiček dosud reflektuje vztah (individuální či kolektivní) paměti a práce dějepisce, zvláště s ohledem na jeho pozici v současné společnosti, která bývá často redukována na roli objektivního „objevitele historické pravdy“. Taková (sebe)reflexe předpokládá přiznání vlivu individuálního světového názoru historika (komplexu názorů a postojů formovaných výchovou, vzděláním, vzpomínkami, generační příslušností a podobně) na jeho vědeckou činnost. Autor studie nabízí dvě možné a vzájemně se doplňující cesty k poznání historikova světového názoru: jednak prostřednictvím vlastních svědectví a prohlášení z jeho osobněji laděných textů a egodokumentů (eseje, rozhovory, vzpomínky, příspěvky na sociálních sítích), jednak analýzou jeho vědeckých textů (časopiseckých studií, knižních monografií, recenzí). Oba přístupy autor dokumentuje na konkrétních příkladech z produkce historiků a historiček českých soudobých dějin. V závěru studie pak nastiňuje cíle a smysl zkoumání historikova světového názoru.The aim of this study is to present the opportunities for research into the worldview of historians, especially historians focused on contemporary history, where it can be assumed that their set of values may influence their interpretation of the rela-tively recent past. The author first defines the notion of worldview and justifies the analytical use of this concept in historiographical texts. He also considers the relationship between memory, history and historiography in the given context. The author states that not many Czech historians have so far reflected on the relationship between (individual and collective) memory and the work of the historian, especially with regard to his or her position in contemporary society, which is often reduced to the role of an objective “discoverer of historical truth”. Such (self)reflection presupposes the acknowledgement of the influence of the historian’s individual worldview (a complex of opinions and attitudes shaped by upbringing, education, memories, generational affiliation and so on) on his or her scholarly activity. The author of the study offers two possible and complementary ways to learn about the historian’s worldview: first, through his or her own testimonies and statements from more personal texts and ego-documents (essays, interviews, memoirs or social me-dia posts), and second, through the analysis of his or her scholarly texts (journal studies, monographs and book reviews). The author demonstrates both approaches with concrete examples of works by historians of Czech contemporary history and concludes by outlining the aims and purpose of examining the historian’s worldview. © 2022, Institute of Contemporary History of the Czech Academy of Sciences.

Inventering av biologiskt kulturarv
No full textFältmanual till biologiskt kulturarv Föreliggande skrift är framför allt en fältmanual till biologiskt kulturarv (och ett urval av andra biologiska kulturbärare), en checklista med bilder och beskrivningar. Det tar också upp några aspekter på själva metodiken för inventering, kartering och tolkning. Fältmanualen omfattar de vanligaste aspekterna av biologiskt kulturarv som man kan hitta i svenska landskap från söder till norr. Listan beskriver biologiskt kulturarv huvudsakligen från nivåerna egenskaper, individer och artförekomster enligt RAÄ:s indelning
Structural studies of nanocrystalline oxides
No full textWe report the results of structural studies of samples of nanocrystalline tin oxide, zirconia, magnesia, alumina and silica, prepared by sol-gel techniques (including the addition of silica to restrict grain growth) and high-energy ball milling. XRD, EXAFS/YANES and MAS-NMR analyses were used to characterise the materials. EXAFS showed that nanocrystals of ZrO2 and SnO2 prepared by sol-gel methods are highly crystalline, consistent with previous EXAFS studies of sol-gel prepared nanocrystalline oxides [A.V Chadwick, M.J. Pooley, K.E. Rammutla, S.L.P. Savin, A. Rougier, J. Phys.: Condens. Matter, 15 (2003) 43 L; A.V Chadwick, G.E. Rush, in Nanocrystalline Metals and Oxides: Selected Properties and Applications, (Kluwer, New York), (2002), p. 133.]. In contrast, the sol-gel prepared SiO2 appeared amorphous, even after prolonged heating at 1200 degrees C. The EXAFS of the ball-milled samples showed clearly attenuated signals that cannot be attributed solely to particle size. Ball milling of quartz crystals (which have a simple Q(4)) first broadens the NMR line and then generates Q(3) and then Q(2) lines indicating the generation of amorphous materials in the samples
X-ray absorption studies of the structure of nanocrystalline oxides
No full textX-ray absorption spectroscopy is a prime tool in probing the local structure in condensed matter. This contribution describes some of the applications of this technique to probe the microstructure of nanocrystalline oxides. By the use of specific examples four areas will be covered, namely the effect of grain size and preparation route on microstructure, the locating of dopant sites and the chemical nature of metal/oxide catalysts. The materials involved are tin oxide, lithium mobate, titanium dioxide and copper/ceria
Diffusion in nanocrystalline solids
No full textEnhanced atomic migration was an early observation from experimental studies into nanocrystalline solids. This contribution presents an overview of the available diffusion data for simple metals and ionic materials in nanocrystalline form. It will be shown that
enhanced diffusion can be interpreted in terms of atomic transport along the interfaces, which are comparable to grain boundaries in coarse-grained analogues. However, the method of sample preparation is seen to play a major role in the experiments and there are still many gaps in understanding the detailed mechanisms of diffusion in these systems
Small, but perfectly formed: The microstructure of nanocrystalline oxides
No full textThere is considerable interest in nanocrystalline materials due to their unusual properties that offer the possibility of exciting technological applications. This paper concentrates on the microstructure of nanocrystalline binary oxides as revealed by X-ray absorption studies. It will be shown that these experiments yield a picture of the materials in which, even when the particles are only a few nanometres in size, the crystallites are highly ordered and the interfaces are similar to grain boundaries in normal bulk solids. This is in conflict with earlier ideas where it was often assumed the surfaces of nanocrystals and the interfaces between them were very disordered
