(Table 1) Chemical composition of volcanic rocks from the Mariisky sequence and extrusive vent rocks of the Mary Cape, Schmidt Peninsula (North Sakhalin)

Early Cretaceous volcanic rocks of the Mariisky sequence and Early Cenozoic extrusive-vent rocks of the Mary Cape are exposed at the most northwest of the Schmidt Peninsula, North Sakhalin. In chemical composition, all the rocks are subdivided into four groups. Three groups include volcanic rocks of the Mariisky sequence, which consists, from bottom to top, of calc-alkaline rocks, transitional calc-alkaline-tholeiite rocks, and incompatible element-depleted tholeiites. These rocks show subduction geochemical signatures and are considered as a fragment of the Moneron-Samarga island arc system. Trace-element modeling indicates their derivation through successive melting of a garnet-bearing mantle and garnet-free shallower mantle sources containing amphibole; pyroxene; and, possibly, spinel. The mixed subduction and intra-plate characteristics of the extrusive vent rocks of the Mary Cape attest to their formation in a transform continental margin setting

DIET OF ASIAN BADGER IN THE MOUNTAIN FORESTS OF THE SOUTHERN URALS

We studied the diet of asian badger (Meles leucurus Hodgson, 1847) in the mountain forests of the Southern Urals (Ilmensky state reserve). Main foods of badger are earthworms and insects, while plants (berries), amphibians, reptiles, birds, mammals and mollusks are consumed in smaller amount.Работа выполнена при поддержке программы Президиума РАН «Живая природа» (проект 12-П-4-1048 УрО РАН).

ОЦЕНКА МЕТОДА АНКЕТИРОВАНИЯ ДЛЯ ИЗУЧЕНИЯ РИСКОВАННОГО ПОВЕДЕНИЯ, КАК ФАКТОРА, ВЛИЯЮЩЕГО НА ЗАРАЖЕНИЕ ВИЧ-ИНФЕКЦИЕЙ ТРУДОВЫХ МИГРАНТОВ

We performed evaluation of questioning method for study of risky behavior of HIV infection in migrant workers seeking for medical examination in the Unified Medical Center of St. Petersburg. Using a questionnaire containing a structured interview and a 201 points formalized card for data logging, we subsequently assumed to study risk factors in the home country, Russia and the other countries of residence. Previously the validity of interviews with 40 migrant workers selected by case-control method was being assessed. The case was a person of migrant workers with confirmed HIV infection. The control group without HIV infection had similar characteristics in particular identical ethnic and age characteristics. The ratio of cases and controls was 1:3. It has shown that diagnosis and objectification of risk-related behavior in migrant workers when carrying out a medical examination causes certain difficulties, as they are afraid to get under regulated by the legislation of the Russian Federation limitations on the right to work. The study revealed that the questioning method, a basic tool of identifying risky behavior, has the lack of effectiveness. Nevertheless, a survey has revealed extremely low awareness of participants about HIV infection in general, ways of transmission and ways to prevent it - 85% of the interviewees found low awareness of these issues, or complete lack of relevant knowledge. Differences between groups of HIV-infected and intact migrants were insignificant.Проведена оценка метода анкетирования для изучения рискованного поведения, как фактора, влияющего на заражение ВИЧ-инфекцией трудовых мигрантов, обращающихся за медицинским освидетельствованием в Единый медицинский центр в Санкт-Петербурге. С помощью анкеты, содержащей структурированное интервью и формализованную карту для регистрации данных из 201 пункта, предполагалось в дальнейшем изучение факторов риска в родной стране, России и других странах пребывания. Предварительно оценивалась валидность такого анкетирования на 40 трудовых мигрантах, подобранных по принципу «случай-контроль». В качестве случая рассматривался представитель из числа трудовых мигрантов с подтвержденной ВИЧ-инфекцией. Контрольная группа без ВИЧ-инфекции, имела сходные характеристики, в частности, идентичные этнические и возрастные особенности. Соотношение случаев и контроля было 1:3. Проведенный анализ позволил установить, что диагностика и объективизация рискованного поведения у трудовых мигрантов при медицинском освидетельствовании вызывает известные трудности, так как они обоснованно опасаются попасть под регламентированные законодательством РФ ограничения в получении права на работу. Исследование выявило несовершенство основного инструмента выявления рискованного поведения - анкетирования. Тем не менее, анкетирование выявило крайне низкую информированность участников в вопросах ВИЧ-инфекции в целом, путях заражения и способах ее профилактики - 85% интервьюированных обнаружили низкую осведомленность в этих вопросах или полное отсутствие соответствующих знаний. Различия между группами ВИЧ-инфицированных и интактных мигрантов были незначительными

Urban infant mortality and religion at the end of the nineteenth and in the early twentieth century: the case of Ekaterinburg, Russia

Modern demographers analyse regional and other infant mortality differentials as important factors behind the current life expectancy of Russian citizens. Historically, however, the Russian Empire is simply displayed as one block with high infant mortality rates. Also with respect to cultural background factors, Russia is often perceived as religiously homogeneous with the Orthodox Church dominating the country. In reality, Russia has a long history of coexisting religious traditions. This includes both provinces with a majority of Catholics, Muslims, Buddhists or shamanistic populations as well as territories characterized by religious diversity and significant minority religions. Our project studies minority religious groups in the Urals, a province by the Ural Mountains stretching into Asia. While no territory can claim to be truly representative of this mega-country, we believe that this centrally located province is well suited to show some of the Russian variety, including differential infant mortality among the followers of minority religions, which is the topic of this article. We employ church record microdata to study Catholics, Jews and Old Believers in the main metal-producing city of Ekaterinburg
