The Role of Food and Food Behaviors in Intimate Partner Violence

There is a paucity of research that systematically examines how food behaviors play a role in intimate partner violence (IPV). Therefore, this qualitative study aims to answer the broad question, what role do food behaviors play in intimate relationships? Food behavior narratives emerging from participants of court-mandated domestic violence (DV) offender treatment programs were analyzed using grounded theory methods. Five themes emerged. Two described inflammatory/harmful roles: (1) food as a trigger for anger and violence and (2) food as a mechanism of “othering.” One theme described the role of food behaviors in promoting unequal and equal relationships: (3) food as an embodiment of gender roles. Two themes described reconciliatory/beneficial roles: (4) food as a mechanism of recognition and (5) and food as a representation of group rapport. Food behaviors can escalate into conflicts but can also be used as a tool to resolve conflicts. Limitations and the need for future research are further discussed.

Cholesteric Molecular Tweezer Artificial Receptor for Rapid and Highly Selective Detection of Ag+ in Food Samples

Chiral cholesteric molecular tweezer 7a was synthesized, and its recognition properties for Ag+, Al3+, Ca2+ etc., were investigated by UV and fluorescence spectra. The results showed that in ethanol/Tris (1/1, v/v, pH 7.0) buffer solution, the host molecular tweezer 7a had a specific recognition ability for Ag+, the detection limit was up to 1 × 10−6 mol/L, and other metal ions had little effect on Ag+ recognition. At the same time, the naked-eye detection of Ag+ was realized by the light red color of the complex solution. Furthermore, the mechanism of recognition of Ag+ by molecular tweezer 7a was studied by a nuclear magnetic titration test and computer molecular simulation, and a rapid detection method of Ag+ using host molecular tweezer 7a was established. Through the determination of Ag+ in milk powder, quinoa and other food samples, it was proved that this novel method had a good application prospect for the detection of Ag+ in food.

Pastoral and the Principles of Its Stylization (Based On the Material of Vocal Music)

The purpose of this paper is to reveal the role of stylization as a style­forming principle in the evolution of the pastoral genre based on textbook chamber­vocal compositions (arias by W. A. Mozart), as well as little­known ones. The methodology. The proposed research differs from other studies, which are close in the topic (T. Livanova, A. Korobova, A. Taylor and others), by an interpretative­cognitive approach dictated by the challenges of modern performing practice. A comparative analysis of pastoral semantics in European and Chinese poetics was also used. The results. On the basis of vocal miniatures created in the XX century (S. Vasylenko “Pastoral” op. 45, No. 5 and A. Rudianskyi “Lotus” and “The Flute on the Water” from the cycle “The Lake of White Lotus” (2001), a parallel of the European pastorals and ancient Chinese poetry from the point of view of a pastoral person in different pictures of the world has been drawn. The onto­sonological foundation of the pastoral is made up of a human voice accompanied by a shepherd’s pipe, landscape sound painting (the singing of birds, the murmur of a brook), and the vastness of natural landscapes (plain air). The author develops the conceptual apparatus of the theory of the pastoral to reveal the richness of various composing interpretations of the genre, its dynamics: “semantics of the pastoral”, “ontology of the pastoral image”, “pastoral person”, “pastoral picture of the world”. The topicality of the interpretative­comparative analysis is the conclusion about the necessary principles of stylization of the pastoral: the presence of a genre invariant with its own stable, psychological mechanism of recognition by listeners; historical distancing from the prototype (ancient poetry, baroque opera); creative synthesis of many traditions of the artistic existence of the genre and the signs of its national musical attribution. Poetic text and symbolization of the musical language are also the mechanisms of stylization of the pastoral in vocal music. Musical and poetic symbols, created by the author’s intuition, form a new life for the pastoral in the creative work of the XX century composers. If the composer’s interpretation of the genre invariant of the pastoral has ensured its viability for millennia, then the performer of pastoral compositions is responsible for their genre and style “purity”. The performers must master the technique of recreating the sound­like world of a pastoral person. The practical significance of the topic is confirmed by the fact of the actualization of the pastoral in the performance of the XXI century, due to the systematic inclusion of its samples into the concert repertoire of vocalists (including those from the People’s Republic of China), which requires appropriate historical and theoretical knowledge when modelling the behaviour of a pastoral person in the modern cultural situation.

The Mechanism of Recognition and Withdrawal of Unregistered Medical Devices from Circulation

The paper is devoted to the study of issues related to the powers of Roszdravnadzor to identify unregistered medical devices in circulation and to take response measures to limit their further sale and use by business entities. The authors analyze the features of the implementation of these powers of Roszdravnadzor and the problems arising in law enforcement practice. An analysis of the current Russian legislation leads the authors of the article to the conclusion that the legal regulation of the powers of Roszdravnadzor to recognize the products as unregistered and to make administrative decisions to restrict their circulation on the territory of the Russian Federation is insufficient and contradictory. The lack of proper legal regulation in this area entails negative legal consequences for participants in civil turnover. On the basis of the study, the authors formulates specific proposals for improving the legal regulation of the recognition and withdrawal from circulation of unregistered medical devices using mechanisms of preliminary and subsequent administrative (extrajudicial) and judicial control.

Understanding the Mechanism of Recognition of Gab2 by the N-SH2 Domain of SHP2

Gab2 is a scaffold protein with a crucial role in colocalizing signaling proteins and it is involved in the regulation of several important molecular pathways. SHP2 is a protein phosphatase that binds, through its two SH2 domains, specific consensus sequences presenting a phosphorylated tyrosine located on the disordered tail of Gab2. To shed light on the details of such a fundamental interaction for the physiology of the cell, we present a complete mutational analysis of the kinetics of binding between the N-SH2 domain of SHP2 and a peptide mimicking a specific region of Gab2. By analyzing kinetic data, we determined structural features of the transition state of the N-SH2 domain binding to Gab2, highlighting a remarkable cooperativity of the binding reaction. Furthermore, comparison of these data with ones previously obtained for another SH2 domain suggests the presence of underlying general features characterizing the binding process of SH2 domains. Data are discussed under the light of previous works on SH2 domains.
