The primary research goal is to identify differences and diagnostic features of the phytolith spectra of the steppe and forest phytocoenoses. The paper presents the research results of recent soils from various communities. The authors employ the phytolith analysis method. The isolation of phytoliths from recent soils has been carried out with the help of the maceration method and from plants – the dry ashing method. The authors counted the phytoliths using the Olympus BX-51 light microscope. Additionally, the authors have compiled the spectra using the 2C software. The paper compares the phytolith spectra of plain and mountain steppe phytocoenoses. The comparison reveals that the considered plain communities are more similar in phytolith composition than the mountain ones. The following morphotypes are common for all spectra: low conical rondel particles and psilate ribbed particles. These are the forms that characterize steppe communities. Analysis of phytolith spectra of the mountain forest communities demonstrates that the presence of ribbed particles of psilate is common for all spectra. The common feature of all forest spectra is the presence of psilate symmetrical particles, polylobate trapeziforms, lanceolates (trichomes) with a massive base, and trapeziform bilobate (“Stipa-type”) particles. In the spectra of all pine forests, there is a low content or complete absence of needle phytoliths. Diagnostic features of individual phytocoenoses have not been found. The most significant is the ratio of individual phytolith forms in the phytolith spectrum. The comparative analysis of phytolith spectra of the phytocoenoses in the south of western Siberia is carried out for the first time.

The results of a comparative analysis of the images of giants in the mythological traditions of geographically close unrelated peoples — the Ob Ugrians (Khanty and Mansi) and the Zabolotny Tatars are presented in the article. It is noted that the assimilation and leveling of the features of the giants images in original cultures did not occur, despite the fact that the myths of the West Siberian peoples were subjected to processes of mutual influence. Particular attention is paid to the relationship between the external features and the origin of mythological characters (giants) with the specifics of the geoclimatic landscapes inhabited by the peoples that form the epic. The novelty of the research is seen in the fact that for the first time the genesis, attributes and functions of the mythological heroes of unrelated peoples living in adjacent territories — the Ob Ugrians and the Zabolotny Tatars — are compared. The relevance of the study is due to the fact that the image of a giant has significant prospects in the reconstruction of an ethnic cultural space, since, being one of the most archaic characters in myths, at the same time it remains a part of modern cultural consciousness. The author’s vision of the common and unique features of giants as distinctive characters of the Ob-Ugric and Siberian Tatar mythological systems is presented in the article. The research materials were myths and legends of the peoples of Western Siberia, records of oral stories of the indigenous inhabitants of the region, collected by the authors during field expeditions.

Abstract Background: Due to the common instability caused by political and security issues, Lebanese hospitals have experienced acts of terrorism multiple times. The most recent Beirut Explosion even forced several hospitals to cease operations for the first time in decades—but studies show the preparedness levels for such attacks in similar countries are low. Objective: The aim of this study is to explore the experience of Lebanese hospitals with terrorist attacks. Methods: This qualitative study used semi-structured interviews with various stakeholders to assess their experience with terrorist bombings. Data was analyzed using the thematic analysis method. Results: The researchers found that Lebanese hospitals vary greatly in their structures and procedures. Those differences are a function of 3 contextual factors: location, culture, and accreditation status. Hospitals found near ‘dangerous zones’ were more likely to be aware and to have better response to such events. A severe lack of communication, unity of command, and collaboration between stakeholders has made the process fragmented. Conclusion: The researchers recommend a larger role for the Ministry of Public Health (MOPH) in this process, and the creation of a platform where Lebanese organizations can share their experiences to improve preparedness and resilience of the Lebanese healthcare system in the face of terrorism.

The paper describes the external structures of the late larval stages of two Palearctic myrmecophilous staphylinids:AmidobiatalpaandOxypodahaemorrhoaassociated with theFormicarufaspecies group. This is the first-ever description of the larva ofAmidobia, and the only complete, detailed account of the morphology of this developmental stage in the genusOxypodacurrently available. For the first time in these two genera, 13 and 10 larval diagnostic features, respectively, are proposed. Morphological differences have been established between known and the newly described larvae of five species (genera) of myrmecophilous and one non-myrmecophilous Aleocharinae, belonging to three tribes.AmidobiatalpaandO.haemorrhoaare probably typical, tiny predators, like most other Aleocharinae, including non-myrmecophilous ones. Being very small and highly mobile, they are ignored by worker ants. Not surprisingly, no particular larval morphological modifications were found to enable them to survive among ants. Such features have, however, evolved in the larvae of larger aleocharines, that is, those that are perceived by ants and are wholly integrated with their hosts in the ant nest (e.g.Lomechusa). This comparative analysis of the functional morphology of the larvae of known myrmecophilous Aleocharinae is a springboard to further such studies of these interesting insects.

For the first time, a comparative analysis of organogenesis in Hosta species - H. decorate, H. sieboldiana, and H. lancifolia in the forest-steppe zone of Western Siberia was performed. It was found that the intrarenal formation of generative organs in these species is laid during the growth of monocarpic shoot in May- June. Differentiation of the growth cone of the renewal shoot occurs synchronously from stages III to VIII of organogenesis for 56-91 days. In the early-flowering species H. decorate, the organ-forming process occurs 25 - 27 days faster than in the late-flowering H. lancifolia. Generative organs in the rudimentary inflorescence are formed acropetally. Stages of organogenesis from IX to XII correspond to phenophases from the beginning of flowering to fruiting. In the pre-winter period, the cone of growth of the renewal shoot in all species is at the II stage of organogenesis, with 4 to 6 leaf metamers embedded in its basal part.

Diagnostic features are systematized for the leaf epidermal structure of the Leptotoma Kiritch. et Samyl. The study of the new findings and the revision of the type material of L. kryshtofovichii Srebrod. et Samyl. from the Early Cretaceous of Eastern Transbaikalia reveal the occurrence of occasional stomata on the lateral epidermis as well as the presence of a central or proximal papilla on the subsidiary cells of the stomata, which allows to emend the specific diagnosis. The same sediments yield L. baikalica N. Nosova, sp. nov., that differs considerably from other Leptotoma species in its peculiar set of epidermal characters. For the first time, discrete resin ducts are found in the leaves of Leptotoma. The revision of type specimens of L. tenuis Samyl. and L. prynadae Travina from the Middle Jurassic of Kansk-Achinsk Coal Basin (Krasnoyarsk kray) suggests their affinity to Baiera. The re-investigation of the type material of L. borealis Travina and L. sibirica Kiritch. et Batjaeva from the Jurassic of Western Siberia indicates that these species should be merged, with L. sibirica kept as the priority name. For the first time for the Lower Cretaceous, findings of Leptotoma leaves are reported from the Maastrichtian of the Amur oblast (L. samylinae N. Nosova, sp. nov.).

Chinese motion-emotion metaphor and its social cognitive mechanism are explored, for the first time, with a comparison between Mandarin Chinese, the Yi language and English. The interaction between motions and emotions is the key to do the research from the perspective of cognitive functionalism. Cognitive functionalism argues that language reflects people’s consciousness, and the cognitive aspect of language interacts with the communicative function of language very well. According to this argument, motion-emotion metaphor, as a popular language phenomenon, can testify to such interactions. The comparative analysis of motion-emotion metaphors, from the perspective of cognitive functionalism, in this paper has proved to take the following aspects into consideration: the subjects’ experiences of physical motions and their effects on objects; the universality and the specificity of such experience; the emotions’ observable traits and their related motions; the common knowledge and normal beliefs among the motions’ subjects and their surrounding contexts.

The article proposes to consider a dynamic model of parasitic invasion of fish of the family Cyprinidae by a parasite of the genus Bothriocephalus. The model is built in the MAEcoS program and based on the example of a small lake in the south of Western Siberia. The author describes studies of the parasitic infestation of common carp from one to two years old in pasture rearing during one season. The parasite is taken into account in the model by a value proportional to the number of infected fishes and is described by a function with a lagging argument. The transition of uninfected fish to infected fish, mortality and the influence of predators are taken into account. This study was conducted for the first time.

The paper deals with comparative analysis of occupations in the regional labor market. Occupation is treated as a multi-dimensional space of characte- ristics, whereas a scalar form of a characteristic makes it possible to carry out a comparative analysis of occupations. Using cluster analysis of a pilot region indicators five meaningfully interpretable clusters of occupations were identified, reflecting their regional specificity.

On the basis of author's graphical analysis method, the typification of lake ecosystems transformation scenarios depending on the size of lakes was carried out. It was confirmed that the type of transformation depends not only on size of the lake, but also on the landscape and climatic region in which it is located. The distinctive features of lake ecosystems transformation types in the European part of Russia and in Western Siberia were analyzed and compared.
