Morphologic and AFLP analysis of relationships between tulip species Tulipa biebersteiniana (Liliaceae)

In populations of four species of tulips (Tulipa biebersteiniana, T. patens, T. scytica and T. riparia) from the Volgograd, Kurgansk, Orenburg, and Chelyabinsk regions and the Republic of Bashkortostan, genetic diversity was studied by means of morphological and AFLP analysis. A morphological analysis of seven quantitative and two qualitative criteria was carried out. Three selective EcoRI/MseI primer pairs allowed one to genotype 81 individuals from 13 tulip populations with 87 loci. The low level of variability by AFLP loci were revealed in all species, including T. biebersteiniana (P = 20. 41%, UHe = 0. 075), T. patens (26. 97%, 0. 082), T. scytica (27. 53%, 0. 086), and T. riparia (27. 72%, 0. 096). According to the AMOVA results, the variability proportion that characterizes the differences between the four Tulip species was lower (FCT = 0. 235) than between populations within species (FST = 0. 439). Tulipa patens is well differentiated by means of Nei's distances, coordination, and analysis in the STRUCTURE program. An analysis in the STRUCTURE revealed four genetic groups of tulips that are not completely in accordance with the analyzed species. This acknowledges the presence of complicated genetic process in the tulip population. © 2013 Pleiades Publishing, Ltd

Relation of life-resistance with self-assessment and coping strategiesat young people and girls of adolescent age

The article analyzes the results of a comparative study of the links of resilience with coping strategies and self-esteem in boys and girls aged 14-16. The sample consisted of 141 people (90 of them were girls, 51 were boys). As a diagnostic tool, the Muddy Test S. Muddy was used (in adaptation D. A. Leontyeva, E. I. Rasskazova); The questionnaire “Methods of coping behavior” (coping test) R. Lazarus and S. Folkman (in the adaptation of L. I. Wasserman); The method of diagnosis of self-assessment of the personality of Dembo - Rubinstein (modified by A. M. Prikhozhan). Hypothesis of the study was the assumption that there are specific features in the links of viability with self-esteem and coping strategies in boys and girls. Both common and specific for boys and girls connections between the studied variables were revealed.В статье анализируются результаты сравнительного исследования связей жизнестойкости с копинг-стратегиями и самооценкой у юношей и девушек

A social portrait of the Russian trainer

The purposes of this paper are to survey Russian trainers to create a social portrait of the professional group and to identify features, which could be arranged as a foothold for transforming this group to a new level given the demands of the modern economy. This study integrates the use of quantitative and qualitative social research strategies to obtain, aggregate, and analyze data characterizing the professional group of trainers in the Russian vocational education and training (VET) system. The basic research was provided by questionnaires in all federal districts (as recognized by international law) of the Russian Federation. The quantitative poll of trainers was conducted by representative two-level sampling. A number of tables and charts provide a social portrait of the Russian trainer. The statistical data reveal the current level of trainers’ education as well as their length of service, distribution of vocations, and other significant features. The overall conclusion from these findings indicates that a typical representative of this professional group is a woman of average or slightly advanced age with a family, who has a VET or higher education, has served as a training officer for not less than 10 years, and who has either been recruited as a highly skilled worker or as a specialist. A typical representative feels the need to change something in the life and teaching of the young people that she knows. The research into trainers as a professional group was conducted first because of their uniformity, and secondly, their typicality as a pedagogical group. In many respects, the main characteristics of the social portrait are similar to characteristics of other professional groups in the Russian education system, such as secondary and post-secondary school teachers, and VET teachers. The study is based on one country. It is the first and only survey of its type in the Russian Federation. The paper provides a unique analysis of the situation with trainers in the VET system of the Russian Federation. © 2016 Kopnov et al

Modulation of neurotransmitter release by carbon monoxide at the frog neuro-muscular junction

Carbon monoxide (CO) is an endogenous gaseous messenger, which regulates numerous physiological functions in a wide variety of tissues. Using extracellular microelectrode recording from frog neuro-muscular preparation the mechanisms of exogenous and endogenous CO action on evoked quantal acetyl-choline (Ach) release were studied. It was shown that CO application increases Ach-release in dose-dependent manner without changes in pre-synaptic Na+ and K+ currents. The effect of exogenous CO on Ach-release was decreased by prior application of guanylate cyclase inhibitor ODQ and prevented by application of a cyclic guanylate monophospate (cGMP) analog 8Br-cGMP. Pre-treatment of the preparation with adenylate cyclase inhibitor MDL-12330A has completely abolished the effect of CO, whereas elevation of intracellular level of cyclic adenosine monophospate (cAMP) mimicked and eliminated CO action. Application of cGMP-activated phosphodiestherase-2 inhibitor EHNA did not prevent CO action, whereas inhibition of cGMP-inhibited phosphodiestherase-3 by quazinone has partially blocked the effect of CO. Utilizing immuno-histochemical methods CO-producing enzyme heme-oxygenase-2 (HO-2) was shown to be expressed in skeletal muscle fibers, mostly in subsarcolemmal region, karyolemma and sarcoplasmic reticulum. Zn-protoporphirin-IX, the selective HO-2 blocker, has depressed Ach-release, suggesting the tonic activating effect of endogenous CO on pre-synaptic function. These results suggest that facilitatory effect of CO on Ach-release is mediated by elevation of intracellular cAMP level due to activation of adenylate cyclase and decrease of cAMP breakdown. As such, endogenous skeletal muscle-derived CO mediates tonic retrograde up-regulation of neuro-transmitter release at the frog neuro-muscular junction. © 2007 Bentham Science Publishers Ltd

Latent risks of secondary vocational school teachers’ professional activity: results of sociological research

The article presents the results of sociological research of the work of secondary school teachers who do not have psychological and pedagogical education. The analysis of the sociological research data shows that 84.1% of teachers (the re-spondents) having no psychological and pedagogical education are of working age. Among them, 24.6% of teachers belong to the age group of up to 35 years. This leads to the problems and difficulties of modernization of vocational education. The main trends of secondary vocational education development for the next five years are updating of vocational education content, implementation of the federal government standards, professional standards, modern methods and educational technologies in the system of secondary vocational education. All these tasks cannot be fulfilled without a serious pedagogical trainingВ статье приводятся результаты социологического исследования профессиональной деятельности преподавателей СПО, не имеющих профессионально-педагогического образования. Анализ данных социологического исследования показывает, что 84,1 % преподавателей (из числа опрошенных), не имеющих профессионально-педагогического образования, находятся в наиболее активном трудоспособном возрасте. Среди них 24,6 % преподавателей, входящих в возрастную категорию до 35 лет. Это приводит к проблемам и затруднениям в реализации задач модернизации среднего профессионального образования. Основными направлениями развития системы СПО в ближайшее пятилетие станут обновление содержания профессионального образования и внедрение в системе СПО ФГОС, профессиональных стандартов, современных методик и образовательных технологий, которые нельзя освоить без серьезной педагогической подготовки. Для решения поставленных профессионально-педагогических задач сегодня уже недостаточно уровня витагенного и ситуативного педагогического опыта, имеющегося у преподавател

Assessment of adaptability parameters in hulled oat germplasm accessions in terms of their yield in the environments of Kirov Province

Background. Studying the gene pool of a crop under specific soil and climate conditions makes it possible to predict the breeding value of germplasm, while its subsequent inclusion in the breeding process ensures the development of adaptable cultivars capable of implementing their productive potential in large-scale agriculture.Materials and methods. Stability (Si2) and plasticity (bi; PUSS), Ambient Condition Index (Ij), Homeostatic (Hom), Stress Resistance, and Stability Index (Is) were calculated for 12 hulled oat (Avena sativa L.) accessions at the FARC of North-East.Results. Accessions 2981 IG100720 (USA) and k-15293 BORYNA (Poland) showed the best stress resistance, while the highest genetic flexibility was observed in 2981 IG100720 (USA), 3007 IG100848 (Germany), 5330 СSI  590/05,  and k-15178 ‘Begunok’ (Russia). Sources of intensive-type hulled oats: k-15330 CSI 590/05 (Russia) (bi = 1.36)  and  k-15331 CSI 2167/03 (Russia) (bi = 1.60),  were  identified for their higher yield values: 856 and 889 g/m2 under improved growing conditions in 2017, and 365 and 285 g/m2 under dry conditions in 2016, respectively. Medium-intensive accessions k-15178 ‘Begunok’ (Russia) (bi = 1.07), and ‘Skrokolik’ (k-15321, Russia) (bi = 0.97) were identified for the best plasticity. The reference cv. ‘Krechet’ (Si2 = 0.06) demonstrated high yield stability.Conclusion. Sources were selected for hulled oat breeding: 2981 IG100720 (USA), 3007 IG100848 (Germany), and k-15293 BORYNA (Poland), with high stress resistance and plasticity, and plastic sources k-15178 ‘Begunok’ and k-15321 ‘Skrokolik’ (Russia), with stable high yield under varying environmental conditions
