Agribusiness firms requiring a consistent supply of high quality agricultural raw materials have increasingly adopted production contracts to coordinate their supply chains. The present work is aimed to shed light on the role played by sources of asset specificity and uncertainty related to quality strategies in the diffusion of contractual arrangements within the Italian durum wheat sector. To this purpose, factor analyses and probit regressions are estimated in data collected among durum wheat producers. The findings confirm that the role of asset specificity is negligible in presence of staple crops. Moreover, they reveal that experience, transparency and technological stability are all relevant aspects that reduce uncertainty and, in turn, trigger the adoption of production contracts as a governance solution for durum wheat.

Получить полноценную характеристику производственной культуры Древней Руси невозможно без изучения роли сельского ремесла. Многофакторный анализ археометаллографических данных позволил сделать вывод о том, что сельское ремесленное производство представляло гораздо более сложное явление, чем виделось ранее. Древнерусское село не только служило поставщиком сырья в городские ремесленные центры и производило простую в технологическом отношении продукцию, но и воспринимало технологические инновации. Сельские мастера сами могли производить качественные кузнечные изделия и снабжали ими ближайшую округу. It is not possible to obtain full characteristics of the Medieval Russia production culture without examining the role of rural crafts. Multivariate analysis of archaeometallographic data made it possible to conclude that rural crafts were a much more sophisticated phenomenon than previously thought. A village in Medieval Russia not only supplied raw materials to craft centers and manufactured technologically simple products but also adopted technological innovations. Rural craftsmen were able to produce high-quality blacksmith products and supplied them to the nearby population.

AbstractThe modern analytical SEM, which can provide high-quality imaging facilities together with quantitative elemental analysis using an energy-dispersive spectrometer, is finding wide application in the investigation of archaeological problems. Many of these investigations involve the study of silicate and carbonate-based artefacts which may be relatively unmodified from their original geological parent raw materials so that mineralogically based interpretations are often appropriate. In this paper we present a series of examples illustrating the role of the analytical SEM in the mineralogical investigation of archaeological problems, including the characterization and provenancing of geological raw materials, the elucidation of the processes used to transform those raw materials into useful objects and the recognition and characterization of changes which archaeological artefacts may have undergone during burial or during storage.

Durum wheat is considered valuable kind of wheat because of its high protein content, carotenoids, and high-quality gluten. In addition, not only the semolina and the porridge are made from durum wheat but also the premium pasta, fine noodles and various biscuits can be made from it. Durum wheat is rich in carbohydrates, proteins, fiber, iron, and vitamin-B, and support weight loss, heart health, and digestive system. Also, durum wheat can be mixed with soft wheat flour and used for increasing the quality of bread. It improves the tastiness of bread and extend the shelf life. In Mongolia, flour manufacturers start milling the wheat with high-gluten first. Therefore, the bad quality wheat is used from mid- February. Due to that we import the high-gluten wheat from abroad. Currently, cultivation in Mongolia where there are no domesticated versions of durum wheat. The price of wheat is being set depending on its seed gluten, which has greatly increased the farmers' interest in growing durum wheat. Flour manufacturers are aiming to produce more products by durum wheat and proposing to cooperate with scientific organizations. In order to create raw materials to replace the imported products and find sort that adaptability of soil and weather condition of Mongolia, to increase the productions’ the Sondor variety of durum wheat is introduced. The variety is early-controlled, with a yield of 2.8 c/ha from the Pletcher variety and, according to economic indicators, can produce up to 252.0 thousand Mongolian tugriks per seed per 1 ha and 168.0 thousand tugriks per hectare. Хатуу буудайн “Сондор” сортын сорт сорилтын дүн  Хатуу буудай нь уургийн агууламж ихтэй каротиноидууд, онцгой чанартай цавуулагтай тул үнэ цэнэтэйд тооцдог. Түүгээр ширхэгтэй гурил (семолина), хүүхдийн будаа хийхээс гадна дээд зэргийн гоймон, нарийн гоймон, төрөл бүрийн жигнэмгийг зөвхөн хатуу буудайгаар хийнэ [1].

In the article the noticeable role of bronzocasting production is considered on the settler monuments of scythian time in the Tarashchanskiy district of the Kyiv area. Among the numerous testimonies of bronze casting production and trade in metals the two most interesting items are bronze treasures, recently discovered in the villages of Lisovichi and Dibrovka in Kyiv region. Each contained about 300 bars with a length of 40.5 and 22 cm (Lisovichi), 41 cm (Dibrovka), total weight about 30 kg. We can assume a different purpose of bronze bars: blanks for specific products, raw materials for smelting, the equivalent of money. Spectral analysis of the products showed that they are made of high-quality tin bronze with a high admixture of iron (2.58 %, Lisovichi). Titanium content (4.39 %, Lisovichi) remains unclear (is it a natural impurity in raw materials?) According to the place of discovery (on settlements), treasures of bars can be dated to Scythian time (the end of 6th—5th century BC?), although more late dates are not excluded.

Abstract. Thyroid hormones play an important role in body homeostasis by facilitating metabolism of lipids and glucose, regulating metabolic adaptations, responding to changes in energy intake, and controlling thermogenesis. Proper metabolism and action of these hormones requires the participation of various nutrients. Among them is zinc, whose interaction with thyroid hormones is complex. It is known to regulate both the synthesis and mechanism of action of these hormones. In the present review, we aim to shed light on the regulatory effects of zinc on thyroid hormones. Scientific evidence shows that zinc plays a key role in the metabolism of thyroid hormones, specifically by regulating deiodinases enzymes activity, thyrotropin releasing hormone (TRH) and thyroid stimulating hormone (TSH) synthesis, as well as by modulating the structures of essential transcription factors involved in the synthesis of thyroid hormones. Serum concentrations of zinc also appear to influence the levels of serum T3, T4 and TSH. In addition, studies have shown that Zinc transporters (ZnTs) are present in the hypothalamus, pituitary and thyroid, but their functions remain unknown. Therefore, it is important to further investigate the roles of zinc in regulation of thyroid hormones metabolism, and their importance in the treatment of several diseases associated with thyroid gland dysfunction.

Compared to the attention that children's literature scholars have paid to the construction of childhood in children's literature and the role of adults as authors, mediators and readers of children's books, few researchers have made a systematic study of adults as characters in children's books. This article analyses the construction of adulthood in a selection of texts by the Dutch author and Astrid Lindgren Memorial Award winner Guus Kuijer and connects them with Elisabeth Young-Bruehl's recent concept of ‘childism’ – a form of prejudice targeted against children. Whereas Kuijer published a severe critique of adulthood in Het geminachte kind [The despised child] (1980), in his literary works he explores a variety of positions that adults can take towards children, with varying degrees of childist features. Such a systematic and comparative analysis of the way grown-ups are characterised in children's texts helps to shed light on a didactic potential that materialises in different adult subject positions. After all, not only literary and artistic aspects of children's literature may be aimed at the adult reader (as well as the child), but also the didactic aspect of children's books can cross over between different age groups.

Staff members at a movie company Daiei, known for presumably the world’s best film technology, continued to produce movies for several months even after the company went bankrupt. It was because they desired to make outstanding films. A director can create a high-quality film by combining the skills and ideas of such staff. Akira Kurosawa named the group that could produce excellent works the “Community of Talents”. By using research on a community as a clue, this paper aims to highlight how the “Community of Talents” is organized. First I point out that a “Community of Talents” is formulated primarily by the labor of the staff based on Kumazawa’s “Community on the Shop Floor”. The paper subsequently refers to research by Heinrich Nicklish, a representative researcher on the study of community in Germany, in an attempt to verify that the community is a group of people established on functions. Lastly, the paper explores Guido Fisher’s research to reveal the role of democratic leadership centered on the director who transforms the objectified staff in the organization into an independently-minded presence and help them prove their abilities. The paper continues to emphasize the significance of leadership in the formation of the “Community of Talents”.
