Change in the state of an exploited fish population: From individual indicators to integral assessment

We adapted the approach used for the integral assessment of the status of ecosystems in order to assess population status. Classic theoretical concepts of fish population dynamics are the basis of this approach. The convolution of information about changes in several structural and functional characteristics into one integral index was performed using the analytical function of desirability. The index varied 0 to 1 and quantitatively characterizes the state of the population. This approach was tested on the example of the European grayling Thymallus thymallus (Linnaeus, 1758), inhabiting the Vym River (basin of the Northern Dvina River, North of the European part of Russia). The materials were collected during the environmental monitoring carried out by the Institute of Biology of Komi Science Centre of the Ural Branch of the Russian Academy of Sciences (IB FRC Komi SC UB RAS) in 2002, 2005–2019. The population parameters used in the calculations (relative abundance; average and maximum age of fish; the proportion of matured individuals in the 4+ age group; average specific growth rate of fish at the age of 6+; body weight of fish in the age group 6+) were characterized on the basis of the control net catches. Compared with the period 2005–2006, the value of the integral index in 2015–2018 decreased by almost two times. This indicates deterioration in the condition of the grayling group in the study area. There were no serious disturbances in the fish habitat in this area. The main hydrochemical and hydrobiological indicators have not changed significantly. The main reason for the observed changes is likely the significant increase in the impact of recreational anglers. The proposed integral index may be useful both for assessing the state of fish populations and for developing measures for the rational management of fish stocks

Periodization of the naturalization process of kilka (Clupeonella cultriventris) in Dneprodzerzhinsk and Kremenchug reservoirs

В двух водохранилищах Днепровского каскада выявлены периоды прохождения фаз натурализации массового вида рыб, что важно для изучения данного процесса у различных видов в разных регионах и для понимания роли чужеродных видов в их рыбном населении. Натурализация тюльки в рядом расположенных водоемах протекала по-разному. В акватории будущего Днепродзержинского водохранилища этот вид проник за два года до строительства плотины, а в Кременчугское он вселился через четыре года после его создания. Детализация начала фаз натурализации основана на анализе динамических фазовых портретов уловов тюльки исследовательским траломВ двух водохранилищах Днепровского каскада выявлены периоды прохождения фаз натурализации массового вида рыб, что важно для изучения данного процесса у различных видов в разных регионах и для понимания роли чужеродных видов в их рыбном населении.

Information about time of these phases is important for analysis of changes in invader population and understanding of the role of alien species in analysed water bodies. The aim of this work is to detect the time of occurrence of naturalization phases for the kilka in the Dniprodzerzhinsk and Kremenchug reservoirs. The analysed material includes the own data, archives of the Institute of Fisheries of the NAAS, commercial fishery statistics and literature sources. A dynamic phase portrait method was applied for detailing the time of beginning of different phases. It was established that kilka had been already present in the Dniprodzerzhinsk reservoir at the phase of II (reproduction) before its construction, and after 1967 it became the predominant pelagic species. As for the Kremenchug reservoir, kilka invaded that water body 4–5 years after its construction. It quickly passed phases I and II and by 1968 became abundant commercial species. Thus, it was found that kilka’s naturalization phases occurred differently in these nearby water bodies: in the future Dniprodzerzhinsk reservoir area, this species penetrated two years before impoundment; while in the Kremenchug reservoir it penetrated four years after the construction. Four to five years were needed for passing first three phases of kilka naturalization in the studied reservoirs. Faster progression of the phases I and II of its naturalization in the Kremenchug reservoir compared to the Dniprodzerzhinsk one indicates on better life conditions in the first water body at the moment of invasion. Currently, the studied kilka populations pass the phase IV of naturalization, which is characterized by fluctuation of population abundance

Myth in the structure of national consciousness

In the context of globalization processes, the problem of nations and national selfconsciousness has become one of the most widely discussed in the modern social sciences and humanities. Within the framework of globalization approaches, a nation is viewed as a transitional formation between traditional locality and planetary interdependence. According to modern theories, the model of a nation is built on the basis of Western European developmental patterns. From such viewpoint, the characterization of ethnicity is rejected, as a feature of “primitive”, “pre-political” societies as marginal groups doomed to assimilation into the existing structures. The central problem of ethnical belonging is the issue of origin, the restoration of cultural and historical memory and the construction of the “appropriate past”, which would assist in solving the problems of the present. The core of any national culture is national-ethnic self-consciousness which is the key factor in the national identity formation. It is pointed out that certain types of myths are inseparable from the ethnic identity. Today, researchers speak of the process of “remythologization”. For Russia, which has always been a multiethnic state, the problem of scientific definition of nations, ethnic groups, national and ethnic consciousness has a special practical significance. In Russia and the post-Soviet space, the activation of mythological thinking has its own specifics.Keywords: Nations, Ethnicity, National consciousness, Myth, Globalizatio

Attainment grouping in English secondary schools: A national survey of current practices

Attainment grouping is a prevalent yet controversial practice, used in most English schools and on the rise internationally, despite evidence that it is detrimental to the majority of pupils. In England, no data is routinely recorded regarding these practices, and most research on student outcomes depends on a simplistic dichotomy between pupils grouped and ungrouped by attainment. We present the findings of a survey of attainment grouping practices in English secondary schools, providing an updated picture of the profile of attainment grouping in English and mathematics for students aged 11–16. Grouping in sets is dominant for mathematics and, while variants on mixed attainment grouping are frequently used for students aged 11–14 in English, the frequency of setting increases as students progress through secondary school. Schools with disadvantaged intakes are more likely to group by attainment. We also find that grouping practices are much more complex and dynamic in enactment than is implied by much of the literature and that teachers report that many schools adapt grouping strategies to meet the perceived needs of different cohorts. We provide an updated conceptualisation of grouping practices as a continuum and discuss its implications for current and future research.Education Endowment Foundation.

Electron Bernstein waves emission in the TJ-II Stellarator

Taking advantage of the electron Bernstein waves heating (EBWH) system of the TJ-II stellarator, an electron Bernstein emission (EBE) diagnostic was installed. Its purpose is to investigate the B-X-O radiation properties in the zone where optimum theoretical EBW coupling is predicted. An internal movable mirror shared by both systems allows us to collect the EBE radiation along the same line of sight that is used for EBW heating. The theoretical EBE has been calculated for different orientations of the internal mirror using the TRUBA code as ray tracer. A comparison with experimental data obtained in NBI discharges is carried out. The results provide a valuable information regarding the experimental O-X mode conversion window expected in the EBW heating experiments. Furthermore, the characterization of the radiation polarization shows evidence of the underlying B-X-O conversion process.Comment: 21 pages, 14 figure

A NEW APPROACH TO THE DOSING DEGREE OF ANTERIOR TRANSPOSITION OF THE INFERIOR OBLIQUE MUSCLE SURGERY FOR VERTICAL STRABISMUS

Introduction. Strabismus is the  deviation  of one  eye from  a  common  fixation point, associated  with impaired  of binocular  vision. The eye’s position in horizontal and vertical directions looking straight determines the t ype of strabismus. Despite  numerous reports of surgical  interventions on the  vertical action  muscles, there is no a differentiated approach to the  treatment of patients with this pathology. The search for the optimal methods and principles of surgical  treatment of vertical strabismus caused by hyperfunction  of the inferior oblique muscle, testifies to the relevance of developing new approaches to eliminate hypertropia  depending  on its severit y.The purpose — to  develop  a  method  of dosing  the  degree of anterior transposition of the  inferior  oblique muscle  in the  surgical treatment of vertical  strabismus caused by hyperfunction  of the  inferior oblique muscle  depending  on severit y,  and  to  evaluate  its clinical efficacy.Patients And Methods. In the  period  from January 2013 to October  2015 60 children  (96  eyes) aged  from 3 to 17 years  with a vertical strabismus caused by hyperfunction  of the inferior oblique muscle  were  followed-up. All patients underwent a complete pre  — and postoperative examinations. All patients received  surgical  treatment — weakening  of the inferior oblique muscle through  its anterior dosed  transposition.Results. There  were  no intraoperative complications and  specific complications t ypical for weakening  surgeries on the  inferior oblique muscle. Overcorrection  wasn’t  registered neither  in the  case of surgical  treatment of large vertical angles  of strabismus, no small vertical deviations.  Restriction of mobilit y of the eyeballs wasn’t recorded throughout the observation period  in any patient. Residual  hyperfunction  of the  inferior oblique muscle  was  in 3 patients (5%). It did not exceed  the value of the  vertical,  with the  fusion and  did not  require  additional surgical  treatment.Conclusion. The technology  will significantly improve  the  efficiency and  safet y  of treatment, reduce the  risk  of complications and  the  duration  of surgery and  anesthesia, the number of surgical treatment stages, to create optimal conditions  for the rehabilitation  of visual functions  in children
