From quantitative measurement to understanding public demand: Exploring non-survey methods in applied regional research

The article builds on the well-developed problem of studying trust in society towards social institutions, as well as between individuals. Currently, contact quantitative sociology faces a number of challenges, and the level of consent to participate in surveys is steadily falling. In order to reliably assess public opinion, non-contact tools for studying the digital environment are already required. The application of non-survey techniques for collecting big data using a pre-formed thesaurus allows us to select data for analysis and circumvent the problems associated with respondent recruitment. The application of SML approach to analyze digital publications of Russian-speaking users from Novosibirsk (more than 450 thousand publications) collected in 2020 has been considered. The combination of quantitative and qualitative methods allowed us to describe the audience and categorize the areas of public distrust and dissatisfaction. The application of this approach can be useful for managerial tasks aimed at increasing trust in society. Thus, the study is a valuable contribution to the development of modern sociology and its applied aspects

Application of bent crystals at IHEP 70-GeV accelerator to enhance the efficiency of its usage

Bent crystal was extracting 70-GeV protons with average intensity 4*10^11 (as measured in external beamline) per spill of 1.6 s duration, in parallel to the simultaneous work of two internal targets in the accelerator ring. An additional crystal, placed in the external beamline, was deflecting a small part of the extracted beam with intensity 10^7 protons toward another physics experiment. Crystal-extracted beam had a typical size of 4 mm by 4 mm fwhm at the end of the external beamline. Measurements for the extraction efficiency and other characteristics at the simultaneous work of four experimental set-ups are presented. With crystal working in the above-said regime during one month, no degradation of channeling was observed. The studies of extraction efficiency have been continued with new crystals.Comment: 6pp. Presented at EPAC 200

Ferroelectric C* phase induced in a nematic liquid crystal matrix by a chiral non-mesogenic dopant

We report on a ferroelectric chiral smectic C (C*) phase obtained in a mixture of a nematic liquid crystal (NLC) and a chiral nonmesogenic dopant. The existence of C* phase was proven by calorimetric, dielectric and optical measurements, and also by X-rays analysis. The smectic C* which is obtained in such a way can flow, allowing to restore the ferroelectric liquid crystal layer structure in the electro-optical cells after action of the mechanical stress, as it happens with the cells filled with NLC. The proposed method of obtaining smectic C* material allows us to create innovative electro-optical cell combining the advantages of NLC (mechanical resilience) and smectic C* (high switching speed

Super-Ehlers in Any Dimension

We classify the enhanced helicity symmetry of the Ehlers group to extended supergravity theories in any dimension. The vanishing character of the pseudo-Riemannian cosets occurring in this analysis is explained in terms of Poincar\'e duality. The latter resides in the nature of regularly embedded quotient subgroups which are non-compact rank preserving.Comment: 1+55 pages; 15 Tables, 6 Figures; v2 : some clarifications added in Sec. 1 and in App.

КОРЬ У ДЕТЕЙ В СОВРЕМЕННЫХ УСЛОВИЯХ

Children and adults of any age and any social and professional groups are susceptible to the measles infection. Measles may lead to the development of severe disease forms and complications; it remains one of the main causes of death among infants around the world, despite a safe and effective vaccine. A clinical observation of children of 5 months to 14 years of age (n = 44) with measles hospitalized to a specialized in-patient department was conducted. Examination of all children included history taking and daily medical examination throughout the inpatient treatment with the evaluation of intensity of clinical symptoms. It is shown that in modern conditions measles in children is registered mainly in the age group of 5 months to 3 years (81.8%), mainly in unvaccinated children (95.5%), and typically takes a moderate-severe form (95.4%). Strenosing laryngotracheitis and obstructive bronchitis are among the specific measles complications.Коревой инфекцией болеют дети и взрослые любого возраста, различных социальных и профессиональных групп. Корь опасна развитием тяжелых форм болезни, осложнений; она остается одной из основных причин смерти среди детей раннего возраста во всем мире, несмотря на наличие безопасной и эффективной вакцины. Проведено клиническое наблюдение за больными корью детьми в возрасте от 5 мес до 14 лет (n = 44), госпитализированными в специализированный стационар. Обследование всех детей включало сбор анамнеза, ежедневный врачебный осмотр на протяжении всего периода стационарного лечения с оценкой выраженности клинической симптоматики. Показано, что в современных условиях корь у детей регистрируется в основном в возрастной группе от 5 мес до 3 лет (81,8%), преимущественно у непривитых (95,5%), протекает типично, как правило, в среднетяжелой форме (95,4%). Среди специфических осложнений кори преобладали стенозирующий ларинготрахеит и обструктивный бронхит

The evolution of private provision in urban drinking water: New geographies, institutional ambiguity and the need for political economy

Empirical research paints a dynamic picture of the evolution of private provision in urban drinking water. A second wave of privatisation is clustered in a key group of countries, distinguished by the rise of new domestic private and quasi-private providers. This is, however, taking place in the presence of a counter-dynamic of remunicipalisation. In response to the complexity in provision arrangements revealed, three case studies are used to illustrate how different power balance configurations in the state-society-capital complex inform particular institutional arrangements. In Germany, civil society pressure challenged private capital resulting in the reinstatement of municipal control in Berlin, but at high long-term costs. In Russia, disempowered civil society has watched as the ruling regime exploits the support of international public agencies and foreign investors, while carefully safeguarding the interests of domestic private capital. In China, different levels of the state have promoted quasi-state actors into global corporations, managing the entry of international capital in order to bolster domestic support for desired political reforms. Public responsibility, and equally the re-assertion of public control after a period of private provision, may not in itself secure net social benefit where the right of capital to profit is put before broader social considerations
