Halamphora yongxingensis sp. nov., a marine benthic diatom isolated from an intertidal reef around the Yongxing Island, South China Sea (16° 58’ 43.3” N, 112° 14’ 41.7” E), is described in this study on the basis of light and electron microscopy. This diatom is also compared with related taxa such as Halamphora subturgida (Hustedt) Levkov and Amphora subtropica Wachnicka & Gaiser. In addition, phylogenetic analyses based on 18S rDNA and rbcL gene were also conducted. The results revealed that H. yongxingensis was clustered into the Halamphora clade, closely related to Halamphora montana (Krasske) Levkov. We discuss morphological differences between H. yongxingensis and H. montana.

First Time

We present a new marine benthic diatom genus Cymatosirella gen. nov. The genus belongs to the family Cymatosiraceae and has been assigned to the subfamily Extubocelluloideae on the basis of ultrastructural cell wall features. It has isovalvate cells with undulate valves and is characterized by the absence of tubular processes and the occurrence of hollow spines which are observed for the first time in the Cymatosiraceae. The new genus contains four species, two of which are transferred from the genus Cymatosira, viz. Cymatosirella capensis comb. nov. and Cymatosirella minutissima comb. nov., and two which are new to science, viz. Cymatosirella benguelensis sp. nov. and Cymatosirella taylorii sp. nov. Cymatosirella capensis is chosen as the generitype. The new genus includes a group of very small taxa inhabiting the intertidal zone of the Atlantic Ocean with three species in South Africa and one in Europe. C. capensis was originally described by Giffen from Langebaan Lagoon (a shallow marine inlet in the southern part of Saldanha Bay, Western Cape Province), on the basis of light microscopy only, and has to date only been illustrated by line drawings. C. minutissima, so far only known from the Westerschelde estuary (The Netherlands), has previously been documented in more detail using both light and electron microscopy. Here, we present the results of detailed light and electron microscopical investigations of C. capensis, both from its original type material and from recently collected samples from the type locality and neighboring littoral areas in the Western Cape Province, and of the new species C. benguelensis and C. taylorii, also from Western Cape localities. All species are compared with similar small taxa belonging to the Cymatosiraceae, subfamily Extubocelluloideae.

The state is a complex social entity that plays a system-forming role in society. This is reflected in the implementation of many functions inherent in the state as a social institution. Their combination implies a directed influence on the elements that interact in a certain situation, in order to achieve goals in the most effective ways. Such goals seem significant in the context of a certain set of socially useful aspects of life. The implementation of public administration in such conditions actualizes its social orientation, which is based on a scientific approach using modern information and communication digital technologies. This approach should be based on social modeling, which is a specific way of knowing the corresponding aspect of being. Its specificity lies not only in the formalization of knowledge about social structures and processes, but also in the reflection of controlled and spontaneous processes, the awareness of the necessary actions and the will to carry them out in the interacting subjects – actors and building by them of a logically related model of behavior. At the same time, a feature of cognition is the maximum approximation of the formed image to a real process or phenomenon. This is achieved by taking into account the largest number of factors in their relationship with each other, as well as goals of creating the model and the results expected from its implementation. Within the framework of social modeling, there are objective ways to form a behavioral image that allow you to predict the direction and content specifics of the development of many social processes. The article considers the main areas of application of social modeling in public administration: assessment of the effectiveness of management bodies in the monitoring mode, development of strategic decisions, their translation into technological formats, digital representations of strategies and technologies.
