Gender Differences in Customer Behaviour in the Aspect of Odd-Even Pricing

This paper describes the experiment conducted in order to support or reject the hypothesis that the effect of the odd pricing technique depends on the gender of the customer. Analysis of the recent studies in the field of customers’ price perception and, more narrowly, the odd-even pricing, failed to formulate the mutually shared point of view on the problem: whether the odd pricing effect exists or not? Empirical evidence from one group of researches prove this effect is significant while other group of researches prove the opposite. This led scholars to the conclusion there are some individual and contextual factors impacting price perception by customers. So we assume one of these factors is gender. In this study, we have made 2 samples including 3 grocery shops each: initial settings and control settings. During all the experiment we were registering the gender of buyers who were purchasing goods from the predetermined list accounting 10 items (for the experiment there were chosen the goods which are well known by the customers, frequently bought, and normally bought in a similar amount by both genders). As a result of the experiment, we’ve found a significant difference in odd pricing effect among genders: female customers are more perceptive to it comparing to male customers.

Роль операции продольной резекции желудка в обеспечении гликемического контроля у пациентов с сахарным диабетом 2-го типа и ожирением

Цель. Изучить корреляцию между контролем уровня гликемии и степенью снижения индекса массы тела у пациентов после бариатрической операции. Материалы и методы. Проведен контроль уровня обмена глюкозы у 84 пациентов с предиабетом и сахарным диабетом 2-го типа, страдающих патологическим ожирением, после операции уменьшения желудка. Результаты. Из 84 пациентов у 30 (35,7%) продолжительность заболевания сахарным диабетом 2-го типа составляла 1 год, у 27 (32,1%) – 10 лет, у 12 (14,3%) - более 10 лет. У 15 (17,9%) пациентов диагностирован предиабет. При изучении антропометрических показателей отмечено снижение массы тела на 38% после операции по сравнению с исходными показателями. Индекс массы тела (ИМТ) снизился с 46,8 (41,3 – 54,3) до 27,6 (25,4 – 30,9) кг/м2 (р = 0,001). Через 2 года после операции общее снижение массы тела по сравнению с исходными показателями составило 42%, а ИМТ снизился до 26,8 (23,1 – 28,4) кг/м2. Ремиссия сахарного диабета 2-го типа в сроки наблюдения 1 - 3 года отмечена у 82 (98,6%) пациентов (уровень гликированного гемоглобина менее 6,0%, глюкозы натощак менее 5,6 ммоль/л). Выводы. Результаты проведенного исследования показали, что продольная резекция желудка у больных с сахарным диабетом 2-го типа эффективна не только для уменьшения ИМТ, но и для коррекции метаболического синдрома. В послеоперационном периоде у них наблюдали стабильность показателей гликемии и углеводного обмена

Rational extraction of arsenic from copper production waste

Practically and theoretically important are studies aimed at creating new methods for purifying copper electrolyte with the removal of such a dangerous impurity as arsenic in a form suitable for the intended use. Using probabilisticdeterministic planning of the experiment, the course of chemical reactions in manganese- and arsenic-containing systems, the directions of reactions and the stability of their constituent phases were studied. Based on experimental data and thermodynamic analysis, the probable behavior of chemical elements and their compounds, the limits of potential and pH, within which a given compound of an element must be stable, are determined. X-ray diffraction identified the formation of manganese arsenate (Mn3(AsO4)2・4H2O) in deposits formed during the extraction of arsenic from a copper electrolyte with manganese (IV) oxide

Heat capacity of nanostructured multiferroics BiFe1–x Zn x O3

The heat capacity of ceramic BiFe1–x Zn x O3 multiferroics has been studied in the temperature range 150–750 K. It is found that the antiferromagnetic transition temperature T N slightly shifts to lower temperatures as the concentration of the substitutional impurity Zn increases. An excess heat treatment has been observed; it is considered as the Schottky anomaly in three-level states

Genetic variation of RFXANK gene in Stavropol sheep breed

Using of NimbleGen sequencing technology for detection of polymorphisms RFXANK gene in Stavropolsheep breed, we found 20 SNPs. That is, two SNP in exons - c.63C>A (non synonymous) in exon II and c.498G>A in exon VI (synonymous). Others SNP is in introns: c.-343T>C, c.- 111T>G, c.187+328G>A, c.338-94G>A, c.632–124G>A, c.713-82G>A, c.187+62G>A, c.188-588G>C, c.188- 127C>T, c.565-44A>G, c.712+309C>T, c.712+354C>T, c.712+309C>T, c.187+394C>T, c.187+469A>G, c.187+71G>C, c.188-670A>G, c.713-107G>T. Some of them are presented together
