Antipodes on the moon

The areas of the maria were determined using a photomap of the visible hemisphere at a scale of 1:5 million and segments of a lunar globe. The results of the measurements of areas of the maria are presented, together with the data of Westfall and Shoemaker and Hackmann. The areas of circular maria, measured from the peaks of the surrounding ridges, and their mean diameters calculated from the area are also presented

Transformation of Dry Steppe Soils under Long Term Agrogenic Impacts in the Area of Ancient Olbia

The results of the study of dark chestnut soils (Kastanozems) differing in the time and intensity of their agricultural use and in the duration of the fallow stage are analyzed. Soil sequences differing in the char acter of their agrogenic changes were studied in the rural area of ancient Olbia with a centuries long history of diverse economic activities, including crop growin

Russian business ethics in the context of national features

In this article, we have reviewed the basic elements of a business ethics that suggest that the basis of ethic is fundamental cultural differences, and therefore they cannot be universal. The article also identified elements that indicate the differences in business ethics in Russia, the United States and European countries. In these work conclusions about the cultural background, we want to make it possible to see the reason why the Russian businessmen and the USA react differently to similar ethical dilemma. В статье проведен анализ основных элементов бизнес этики, которые позволяют утверждать, что в основе этических воззрений лежат принципиальные культурные различия, а следовательно, они не могут носить универсальный характер. Также в статье определены элементы, которые указывают на отличия в бизнес этике России, США и европейских государств. Сделаны выводы о культурных предпосылках, дающих возможность увидеть причину, по которой бизнесмены России и США по-разному реагируют на аналогичную этическую дилемму

We compare some properties of the lowering and raising operators for the classical and free classes of Meixner polynomials on the real line

Study of Posting Activities of Russian Users on Social Media

Content marketing on social media depends on trends in consumer behaviors. A changing focus and emphasis on audience activities on social media are a key optimization problem in social media marketing (SMM). A solution to this problem lies in a field of ongoing empirical studies of posting frequency. In the review of the literature, authors highlight the role of social media as a promising channel for a direct interaction of companies/brands with consumers. Based on theoretical generalizations, authors present a generation sequence of an SMM content strategy. The article also includes an analysis of posting activities of users from Russia on well-known social media. A cost-benefit analysis of posting activities rests upon some factors: socio-demographic characteristics of users, a content format, time and day of the week parameters, etc. Data come from such sources as aggregated statistics of social media and selective interviewing. An analysis of activities for users from Russia has shown that VKontakte is the most popular platform; Instagram is the second, while Facebook is the third. Odnoklassniki and Twitter are less preferred. VKontakte users respond best to short posts. On Facebook, entries with medium-sized texts have got the highest number of responds. On Instagram, long posts work better. The photo format is a leader in all of the social media. The video format has a middle position, while a text is the most inefficient type of content. There is strong differentiation in response time depending on a target audience. Findings have made it possible to present recommendations for optimization of content marketing

Geometric principles for constructing radar panoramas of the surface of Venus: Hypsometric features of the Moon and terrestrial planets

The physographic curves of the moon and terrestrial planets, drawn both for the entire surface as a whole and for individual hemispheres, were compared to discover the common consistencies and individual features in the distribution of hypsometric levels. In 1983 to 1984 the automated interplanetary stations (AMS) Venera 15 and 16 made radar maps of the planet Venus. The synthesized images are the basic initial material for photogrammetric and catrographic processing to create maps of the Venus surface. These principles are discussed
