Context: Phytoplanktonic community structure in an aquatic body embodies the energy transfer through this phase and indicates the tropic status. Objectives: The present study was conducted to assess the phytoplankton abundance and species composition of Mouri River, Khulna, Bangladesh. Materials and Methods: Water samples were collected from six different stations once in a week for a period of 6 months (February- July) 2010. Results: In total 48 different species of 23 genus and 4 families were identified. Phytoplankton abundance varied from 805 to 1788 individuals/L in different stations. The highest abundance was observed for the family chlorophyceae that constituted 27-50.56% of the total phytoplankton biomass throughout the river. Highest number of phytoplankton species (22) was also recorded for the family chlorophyceae. The most diverse genus was Navicula (6). Some aspects of the water quality parameters were measured by regression analysis and significant correlations were also observed between water quality parameters and phytoplankton abundance. Water temperature, pH, DO, Free CO2, alkalinity, hardness, calcium and magnesium showed positive correlations with total phytoplankton abundance where as transparency, TDS, TSS, sulfate phosphate and nitrite showed negative correlations. Conclusion: In most of the cases, phytoplankton abundance and water quality parameters showed greater deviation from the optimum level. However, the results of the present experiment confirmed the polluted water of the river. DOI: http://dx.doi.org/10.3329/jbs.v21i0.22516 J. bio-sci. 21: 27-34, 2013

The article reflects the results of the scientific research carried out by the authors and the experience of practical work with adolescents. The article presents the results of an empirical study of the concepts of life perspectives and recommendations on the organization and content of psychological and pedagogical work aimed at forming a full-fledged life perspective for adolescents living in government institutions. Such work should be an important direction of the developing and corrective activity of the institution that educates adolescents who have fallen into a difficult life situation — the families left without care. Psychological support of the formation of ideas about life prospects will allow adolescents to develop much more adequate ideas about themselves, their abilities, life perspectives, and learn to plan their own life's events. Psychological work on the formation of adequate ideas about life prospects with teenagers raised outside the family will help create the prerequisites for overcoming this category of adolescents between the "dysfunctional past and the present" and the "dysfunctional future," and will contribute to a more prosperous independent life in the future.

The subject of this paper is the question of the stem family, in the sociological literature and in anthropological studies of Ireland. The notion of the stem family is said to derive from the work of the nineteenth-century French sociologist Frederic Le Play (1806–82). Le Play divided the history of the family into three stages. Ancient societies were supposedly characterized by what he called the ‘patriarchal’ family, in which all the sons were retained within the household, over which the oldest member of the family ruled and in which any number of generations resided. Most of the world's population were said however to have experienced their primary socialization in the ‘stem’ family. The stem family was a threegenerational structure which functioned to retain its original location (land and/or house) by means of dispersing most younger members, while preserving the main family stem by a principle of single inheritance. Parents married off and kept within the group only those children nominated as successors. Finally, there was the modern, ‘unstable’ family which formed upon marriage and dissolved upon the death of the parents.

The article presents the results of field research conducted in 2020 on the territory of the Ile-Alatau State National Natural Park. As a result of the conducted research, 32 species belonging to 2 families of hemiptera of the infraorder Pentatomomorpha I were identified. Among them, the predominant species composition of the family Lygaeidae is 21 species (66%), and 11 species are known from the family Aradidae (34%). On trophic specialization, they are divided into mycetophagy (11 species), phytophages (21 species, of which politicology – 16 types, wide oligotherapy – 3, narrow oligotherapy – 2). According to the type of food, both taking into account the number and number of species in the complex of hemiptera, phytophages clearly predominate. According to the number of generations per year, the hemiptera of the Ile-Alatau SNNP are divided into 4 groups: acyclic (different stages of development can be found simultaneously throughout the year) – 11 species, monovoltine (one generation per year) - 15 species, bivoltine (two generations per year) – 5 species, polyvoltine (several generations per year) - 1 species. There are 30 species with mesophilic ecology in the study area, only 1 species is hygromesophilus. Among the hemiptera of the Ile-Alatau GNPP, 19 species (61%) overwinter in the imago stage, 11 species (35%) in the imago and larvae stage, and 1 species (4%) in the egg stage.

The article presents the results of the study of the value structure of 6-7 years old children. The relevance of the study is caused by the role that childhood has on subsequent human development. The basic values that determine human development are formed at the age of 7 years. However, the study of the value sphere of children presents a number of difficulties - the limited methods and techniques that allow us to explore the value sphere of children, the closeness of the family for scientific research, the insufficient social experience of the child himself, differences in the level of communicative development of children and a number of other difficulties and restrictions. At the same time, the use of various research methods - projective, standardized, observations provides empirical data on the structure of values of 6-7 years old children. Both projective and standardized techniques were used in the study. The results show that the development of the value sphere in children 6-7 occurs very unevenly: from complete amorphism to the presence of a clear hierarchical structure. There are confirmed differences in the structure of preferred values among boys and girls. Girls aged 6-7 choose values related to the communicative sphere, while boys of this age are guided by values that are active character.

The article signals the problems of a complex influence that professional work, one of the key values, has over one’s personal life. This issue seems to be the common area of scientific research for both pedagogy and sociology. Based on the EU27 as well as on Polish research results, a thesis has been formulated that professional work may nowadays be a threat to the functioning of the family.

Abstract. This study describes ecological data obtained in a rural area in the State of Mato Grosso, including the insects belonging to the family Culicidae, especially those framed as potential vectors of tropical diseases. In 2015, we collected adult mosquitoes in fragments of forest in a rural area located in Mato Grosso Central West of Brazil. We captured 18,256 mosquitoes of the sub-families Culicinae and Anophelinae and have identified 34 species belonging to 12 genera: Aedes (1 species), Anopheles (8 species), Coquillettidia (1 species), Haemagogus (1 species), Culex (5 species), Psorophora  (5 species), Ochlerotatus (4 species), Deinocerites (1 species),  Mansonia (4 species), Sabethes (2 species), Limatus (1 species), Wyeomyia (1 species). The family Culicidae presented high richness and abundance, established by diversity indexes (Margalef α =3.26; Shannon H' = 2.09; Simpson D = 0.19) with dominance of the species Anopheles (Nyssorhyncus) darlingi Root (89.8%). This species has considerable epidemiological value, considered the main vector of malaria in Mato Grosso. Many species of mosquitoes are vectors of pathogens that cause disease in humans and domestic animals, transmitting pathogens including viruses (arboviruses), filaria worms (helminths) and protozoa.Composição de espécies e distribuição da fauna de mosquitos (Diptera: Culicidae) e sua importância para doenças transmitidas por vetores em uma área rural do centro-ocidental - Mato Grosso, BrasilResumo. Este estudo descreve dados ecológicos de uma área rural do Estado de Mato Grosso e dos insetos da família Culicidae especialmente aqueles enquadrados como vetores potenciais de doenças tropicais.
