ABSTRACTWe report on an initial long-term study of dissolved inorganic and organic carbon (DIC) from Sabino Creek, located in Sabino Canyon, Pima County, Arizona. The purpose of this study was to monitor changes in dissolved radiocarbon (14C) with time and to understand the processes contributing to these variations. Our results span the period 2009–2016 and show a mixing trend between dissolved inorganic and organic carbon modern end-members with an older component. This study provides preliminary information for more detailed research on recycling of organic components in this stream system.

Fathers make definite contributions to infant development and are now spending more time with their children than in many past decades. This article reviews the most compelling research on the developmental importance of fathers, including father–infant attachment and interaction, and differences between maternal and paternal interaction styles. Results of a long-term study of primary caregiving fathers also are presented.

The article is the result of a long-term study of autobiographies and memoirs from the Fund of the First Builders of Uralmash, collected in 1967-1984 and dedicated to the construction of the plant (1926-1934). The question of the role of spatial and temporal markers in the construction of the collective identity of factory workers is considered. Particular attention is paid to the relationship between strong discursive practices and the “weak positions” of the official discourse, which allow authors to independently write their personal history into the history of the plant. The novelty of the research lies in the fact that the Foundation's documents are viewed not as a factual source, but as a way of creating collective and personal identity of factory workers in the process of forming the concept of the FIRST BUILDER and as a body of texts, which reflects the practice of constructing the “Soviet”. It is emphasized that a special perception of space (the plant and the social city of Uralmash) and the placement of oneself in a certain historical era (with the opposition “then-now”) unite most of the Foundation's texts, among the authors of which are workers of the plant of different specialties and social status. It is proved that the texts have a common chronotope associated with the axiological picture of the world and with the practice of social communication through the text.

Despite the long-term study of exudative otitis media, the disease is not well understood. The wide prevalence of exudative otitis media in children and the increase in the incidence during recent decades explain the interest of specialists in the etiology of the disease. The article presents current views on the role of premature birth, gastroesophageal reflux, systemic and local immunodeficiency, disorders in the antioxidant defense system, mucopolysaccharidosis, genetic predisposition, and other factors in otitis media development. Unfortunately, the cause of exudative otitis media cannot always be established, and it requires further experimental and clinical studies in order to develop effective approaches to etiopathogenetically justified, timely and successful treatment of the disease and its implementation in clinical medicine.
