Happy Family, Healthy Kids: A Healthy Eating and Stress Management Program in Low-Income Parent-Preschooler Dyads.

Substantial effort has been invested to combat childhood obesity, but overall effects are disappointing, especially in low-income racial minority children. One possible reason is a lack of focus on the important stress-eating connection. Stress can negatively influence eating behaviors, leading to an increased appetite for high-fat and energy-dense foods. This study aimed to evaluate the preliminary effects of a healthy eating and stress management program targeting multiple theoretical variables on improving eating behavior (dyads' fruit/vegetable intake, emotional eating), food insecurity, anthropometric characteristics (dyads' body mass index, % body fat), cardiovascular health (dyads' blood pressure), and mental well-being (parental stress). A one-group, quasi-experimental pilot study was conducted among 107 low-income parent-preschooler dyads. The 14-week program included a parent component, a parent-preschooler learning component, and a day care-based preschooler component. The program had positive effects on improving dyads' fruit/vegetable intake, food insecurity, body mass index, and blood pressure and parents' nutrition knowledge, self-efficacy, support, food resource management behavior, problem-focused coping, and home eating environment. The overall satisfaction rate was 95.2%, and 88.1% stated that the program assisted their families with having a healthy lifestyle. Results support the preliminary effects of the program on improving health outcomes in rural and urban low-income families. Although warranting further investigation with a more rigorous randomized controlled trial, the healthy eating and stress management program provides a potential solution to the current coexistence of an obesity epidemic and mental health crisis.

Mine or my neighbours’ offspring: an experimental study on parental discrimination of offspring in a colonial seabird, the little auk Allealle

Individual recognition (IR) abilities may result from various ecological and naturally selected features of a species. Complex IR mechanisms should develop when the risk of misidentification of a chick is high. For colonial seabirds, the ability to identify their own brood is crucial to ensure parental fitness. Vocalizations seem to be a key component of most parent–offspring interactions, although few studies have assessed the interindividual differences in seabird chick calls and their potential usage in IR. The little auk (Allealle), which breeds in dense colonies, constitutes a perfect model for testing IR. In this study, we (1) examined chick calls at different stages of the nesting period, and (2) cross-fostered chicks to examine the rate of acceptance/nonacceptance of chicks by parents. We found significant interindividual differences in chick begging and fledging calls. Surprisingly, all cross-fostered chicks in our experiments were accepted by their foster parents, and male parents were as equally likely to accept cross-fostered chicks as females, even though the sexes would be expected to differ in offspring recognition due to different postfledging interactions with the chick. The revealed individuality of chick calls suggests the potential for chick vocal recognition in the studied species, but parent birds may disregard the individual characteristics enabling chick discrimination. This may take place as long as the chick is found in the nest because of the high likelihood that the chick present there is the focal one. However, IR during and after fledging requires further study. Studying the complexity of IR mechanisms is important for better understanding various avian social relationships and interactions.

Correlation of grain protein content with utilitarian characters in breeding samples of winter wheat, created with the involvement of western european ecotypes

Aim. To establish correlation-regression models of dependences of grain protein with the duration of the interphase period "flowering- grain maturity" and grain yield in elite numbers in breeding nurseries. Methods. Field research was carried out at the Institute of Irrigated Agriculture of the National Academy of Sciences in 2019-2021. The object of research was modern winter wheat varieties of the Institute; collection samples of the Western European ecotype that were introduced from France and hybrids created with their participation Research methods are field, laboratory, biochemical, selection-genetic, statistical. Results. The nature of the manifestation of the trait "grain protein" in selection numbers selected from hybrid populations with the participation of Western European ecotypes of soft winter wheat, correlation-regression models of the dependence of protein, grain yield and the duration of the "flowering-maturity" period were established. The duration of the period "flowering-ripeness" ranged from 45 to 52 days in the best numbers, and each original hybrid combination had its own optimum, which determined high yield and protein content of the grain. Conclusions. For each hybrid population created with the participation of parental components contrasting in duration of vegetation, it is necessary to develop a specific selection plan taking into account intra-population correlation-regression models of productivity, grain protein content and the duration of the "flowering-maturity" period.

Method of determination and selection of the best parent components of sugar beet hybrids (Beta vulgaris L.) by their productivity

The purpose of the research was to study the components of crossing and evaluate the efficiency of the obtained experimental sugar beet hybrids. Selection of the best lines for the use as parent components of monogerm hybrids was performed based on their sugar yield.
 Methods. Foreign pollinators of yield direction (rkБЗ4, rkБЗ5, rkБЗ6, rkБЗ7) and Ukrainian CMS lines were used in crosses. Experimental genotypes were obtained as a result of hybridization, recombination and selection. The genotypes were studied in controlled polycrosses and topcrosses. Variety testing was carried out in accordance with the standard protocols.
 Results. On the basis of use various methods of selection, promising genotypes with high adaptive potential were selected. The highest productivity of hybrids (in % to the standard) with CМS1 was 111.3%, CМS2 112.3%, CМS3 108.3%, and with pollinator rkБЗ6орс 103.8%. In combinations with pollinator абБЗ1 824 / CМS3, the resulted hybrid had productivity 111.2%. The hybrids resulted from combination rkБЗ4 644 / МS2 showed productivity of 109.3%, and rk БЗ4 644 / МС3 112.1%. Hybrids with CМS1 and CMS3 testers showed the productivity of 105.9% and CМS2 105.4%. In terms of sugar yield, the best combinations were rkБЗ7мтд / МS1 with 110.8% and rkБЗ7мтд / МS3 with 108.5%. Thus, the efficiency of pollinators made up 101.5%, 101.2%, 102.5% and 102.8%, respectively.
 Conclusions. Selected sugar beet hybrid components have been evaluated by their efficiency, combinational value and tolerance to the environmental conditions. A very high correlation relationship was found between foreign pollinators and Ukrainian CМS lines. It confirms their suitability as parent components of sugar beet hybrids. The efficiency of experimental hybrids depends both on components of crossing and climatic conditions of a zone of cultivation. Promising parent components of sugar beet hybrids have been selected.

Transgressive variation in productivity traits in F2 naked oat hybrids

One of the most effective methods for increasing yield and resistance to abiotic and biotic factors in the environment is genetic selection and improvement of varieties. Solving these tasks is possible using positive transgressions, which are of great practical importance at this stage of selection. The aim of the research was to determine the coefficient of heritability in the broad sense (H2 ) and the degree and frequency of transgressions for productivity traits in second-generation hybrids of naked oat, created by crossing based on the eco-geographical principle and selection of economically valuable biotypes for further breeding work. During 2021, research was conducted on 15 intervarietal hybrids. F2 and parental components were analysed for traits such as plant height, spike length, number of spikelets per spike, number of grains per spikelet, and grain weight per spikelet. Field research methods (phenological observations), laboratory methods (structural analysis of the material under study), and mathematical-statistical methods (objective evaluation of the experimental data obtained) were used. A prominent level of the coefficient was observed for the trait “grain weight per spikelet”, ranging from 0.66 to 0.88 in hybrid populations OM 11-3007/Abel, OM 2803/Abel, Percy Can/Inermis, Percy Can/Abel. The analysis of the second-generation F2 intervarietal hybrids of naked oat allowed the identification of transgressions for all the studied traits. The highest number of positive transgressions was found for the following productivity traits: spike length (Tf 31.82 – 59.09%, Td 7.53 – 15.49%); number of spikelets per spike (Tf 27.30 – 54.50%, Td 8.85 – 26.49%); number of grains per spikelet (Tf 45.50 – 77.27%, Td 16.63 – 27.62%); and grain weight per spikelet (Tf 63.64 – 81.80%, Td 18.12 – 25.36%). The selection-genetic analysis of studying the nature of heritability, frequency, and degree of transgressive variation in spikelet productivity traits of F2 naked oat hybrids allowed the identification of a considerable number of transgressive forms, in which productivity elements vary widely, indicating successful selection work in creating promising high-yielding breeding material

Creation of source material by attracting different varieties of common winter wheat in breeding for adaptability, productivity, and grain quality

The relevance of the subject matter lies in the constant pursuit to improve and improve varieties of common winter wheat by using various genetic resources and breeding methods to achieve better adaptability, higher productivity, and superior grain quality. The purpose of the study was to expand the genetic diversity of common winter wheat, which combines high productivity and adaptability for further breeding in the context of food security. The research uses generally accepted methods and their modifications, which ensured high objectivity of the results obtained. Phenology, morphological studies, and evaluation of breeding material based on economically valuable characteristics were carried out according to the methodology for conducting an expert examination of plant varieties. It was found that the involvement of the Ferrugineum 1239 sample before crossing allows forming a hybrid material with increased resistance against adverse abiotic environmental factors, which was observed on crops of breeding numbers 0284/18/1, 0135/18, 0209/18/1, etc. It was proved that consideration of the nature of inheritance and preservation of features of ear productivity elements at the level of the best parent components in combination with high quantitative features of the number of grains from the main ear, the weight of grains from the main ear, the weight of 1,000 grains in hybrid populations of the first generation, the above combinations of crosses Triticum aestivum var. erythrospermum with Triticum aestivum var. barbarossa, Triticum aestivum var. erythrospermum with Triticum aestivum var. ferrugineum can be valuable in the selection of common winter wheat. The practical value of the study lies in the fact that the findings expand information about the use of erythrospermum and lutescens and other varieties of common wheat in breeding for the productivity and quality of common winter wheat: Triticum aestivum var. barbarossa and Triticum aestivum var. ferrugineum. As a result of the research, the best samples (F4 ) were transferred to the Nosivka Breeding and Research Station for further breeding work

Unveiling the Influence of Hydrated Deep Eutectic Solvents on the Dynamics of Water-Soluble Proteins.

Deep eutectic solvents (DESs) are mixtures of two or more pure compounds (e.g., Lewis or Brønsted acids and bases, anionic and/or cationic species) in a well-defined stoichiometric proportion, with a melting point lower to that of an ideal liquid mixture. These neoteric solvents are highly tunable through varying the structure or relative ratio of parent components and have been evaluated as solvents able to improve biomolecules' performance, specifically their stability and biocatalytic properties. Inspired by a recent crystallographic study, we have explored through molecular dynamics (MD) simulations the dynamic properties of two different proteins (hen egg-white lysozyme and the human VH antibody fragment HEL4) in a (20% w/w) hydrated solution of choline chloride-glycerol (1:2). We have developed proper force fields to account for DES, protein, and DES-protein interactions, which have been calibrated using pair distribution function measurements of pure DES solutions. MD results show that the presence of DES quenches the protein motion, increasing the rigidity of the overall protein structure. Specific interactions among DES components and protein residues, such as those between choline ions and two Tryptophan residues of lysozyme, may amplify the protein-DES interactions and lead to protein crystallization in the presence of hydrated DES. These findings open new horizons to improve or achieve control on protein properties by a proper choice of hydrated DESs used as solvents.

PROFESSIONAL PERCEPTIONS OF DIFFERENCES BETWEEN THE PARENTING STYLES AND COPING RESPONSES OF FATHERS AND MOTHERS REGISTERED WITH THE CHILD PROTECTION SYSTEM

Families registered with the Child Protection System tend to have poor parenting methods, which, in turn, lead to inadequate ways of coping with stress. This makes them highly vulnerable families. These shortcomings tend to be more prevalent among fathers than mothers. By identifying these shortcomings and analysing them, specific strategies can be developed to overcome them. The aim of this paper is to analyse differences between the parenting styles and coping responses of mothers and fathers registered with the Child Protection System, as perceived by the professionals from the said service. A cross-sectional study was carried out based on the perceptions of professionals attached to the Child Protection System. The findings show that the professionals deem that there are significant differences between maternal and paternal parenting models and ways of coping with stress. The mothers were viewed as having more components of appropriate parenting, while the fathers tended to use physical punishment more often. As for coping methods, the professionals observed that the mothers have more previous experience of conflicts, they spend more time preparing to tackle a problem, and they have a greater sense of being able to take possible advantage of the situation. The results point to the need to reinforce and specialize in training strategies for parents. This is because co-parenting has a positive impact on child development and boosts family functioning. Key words Child Protection System, parenting styles, coping responses, mothers and fathers, professional perceptions

Creation and a breeding-genetic study of pollinator lines - sterility fixers and their CMS-analogues in fodder beet breeding for heterosis

Purpose. To create pollinator lines - sterility fixers and their cytoplasmic male sterility (CMS)-analogues and to study their breeding and genetic features for the development of parental components of CMS-based one-sprout fodder beet hybrids.
 Materials and Methods. The study was carried out at the Tobacco Research Station of the National Scientific Center "IA NAAS" (Cherkaska Oblast, Uman) in 2013–2021. Four diploid one-sprout fodder beet populations of hybrid origin were taken as the starting material. Fodder beet lines were created by inbreeding. Analyzing crossings were carried out under paired coarse calico bags. Breeding accessions were tested in accordance with a method developed by scientists of the Institute of Bioenergy Crops and Sugar Beet of NAAS.
 Results and Discussion. The results indicate a fairly high frequency of pollinators - sterility fixers among the one-sprout fodder beet hybrids bred in Uman. The mean across all the initial accessions was 7.5%. One-sprout hybrids KT-7105 2хmm and KZ-1507 2хmm demonstrated the highest incidence Owen type pollinators - sterility fixers. A high level of pollen sterility was intrinsic to the CMS analogues of the O-type lines derived from the initial accessions IM-3319 2хmm and KZ-1507 2хmm (99.1% and 97.0%, respectively). The highest percentage of one-sprout seeds was recorded for the CMS analogues of the O-type lines derived from hybrid accessions KZ-1507 2хmm and KT-7105 2хmm. Fifteen best O-type lines have been selected for further breeding to obtain parental components of CMS-based experimental hybrids.
 Analysis showed that the beetroot yields of the majority of the CMS fodder beet lines were lower than that of the check variety. CMS IM-3319/16, CMS IM-3319/34 and CMS IM-3319/49 were the only lines that yielded at the level of the check variety (80.9–83.6 t/ha), which is attributed primarily to their genetic origin. As to the dry matter content in beetroots, only lines CMS ST-4514/27 and CMS ST-4514/39 significantly exceeded the check variety; the values of the others were similar to that of the check variety. In terms of the dry matter output, except for CMS KT-7105/7, CMS IM-3319/34 and CMS IM-3319/49, most lines were inferior to the check variety.
 Conclusions. We found that the portion of pollinators - CMS fixers in one-sprout populations of fodder beets of different genetic origins was 3.7–11.3%. Fifteen combinable O-type lines with pollen sterility fixing of 96.2–100% and percentage of one-sprout seeds of 96.4–99.3% have been created. Their CMS analogues have been obtained. The created breeding accessions are a valuable starting material for the selection of parental components and generation of highly productive CMS-based one-sprout fodder beet hybrids

Наследование признака высокого содержания олеиновой кислоты в масле семян F2 и поколения BC1 рапса озимого (Brassica napus L.)

The aim of the work was to study the patterns of inheritance of the trait of high oleic content in the F2 and generation BC1 of winter rapeseed in order to obtain new knowledge about the genetic mechanisms of the high oleic acid contents in seed oil and scientifically based approaches to the development of the breeding germplasm with a high content of oleic acid. The studies were carried out in 2021– 2022 in the field. The material was reciprocal F1 hybrids from crossings of the high-oleic line VN-1848 (79.3%) and two lines from the cultivars Sarmat and Selegor of VNIIMK breeding with the traditional content of oleic acid in seed oil – 62.1 and 60.5%, respectively. Hybrids F1 were used to produce BC1 seeds. F2 and BC1 generations were obtained in 2022. In F2 hybrids, splitting into two phenotypic classes was observed in a ratio of 15 : 1. The first one included lines with oleic acid content in seed oil less than 79%, the second one – lines with high rates of this trait at the level or higher than the parental high-oleic component (18 : 1 > 79%). This proposes the control of a trait by two pairs of non-allelic genes with an additive effect. As a result of backcrosses using the high-oleic lines VN-1848 as the maternal component, 55 genotypes with a low content of oleic acid (18 : 1 < 79%) and 11 genotypes with high levels of this trait (18 : 1 > 79%) were obtained. This corresponded to a splitting ratio of 3 : 1. All χ2 values turned out to be less than 3.8, p > 0.05.The results of the studies confirm our assumption that the oleic acid content in seed oil is controlled by two pairs of non-allelic genes; the manifestation of this trait in plants is observed only when all alleles are in a homozygous recessive state.

The Indicators of Effective Parenting: A Qualitative Study

Background: Parents are the main caregivers in raising children, and the quality and quantity of knowledge of parenting styles and child-rearing practices are essential for improving the growth, health, and correct upbringing of children. Thus, correct upbringing is one of the very important issues as it requires parental responsibility. To this end, the present study aimed to identify the components of effective parenting. Methods: This study was conducted using a conventional qualitative content analysis method. The participants were 9 family counseling specialists in Ahvaz, who were selected using homogeneous purposive sampling. The data were collected through in-depth and exploratory interviews. The collected data were analyzed using the six-step thematic analysis method proposed by Braun and Clarke. Results: The analysis of the participants’ experiences revealed 5 main themes in effective parenting, including conscious knowledge, cohesion and intimacy in marital relationship, scientific application of direct and indirect parenting practices, a structured family, and creating a context for growth and availability. Conclusion: The results reported in this study can have some implications for parents in using effective child-rearing practices. Besides, family counselors and psychologists can use the results of this study to increase parents’ awareness of effective parenting components and patterns by teaching the components of effective parenting to parents.

Inheritance of valuable economic characters in F1 hybrids of spring pebble vetch in the eastern part of the forest steppe of Ukraine

Purpose. To investigate the inheritance of the main valuable economic traits of created breeding material of spring pebble vetch under conditions aridity intensification. Methods. Field, visual, measuring, weighing, quantitative, laboratory, mathematical-statistical. Results. 18 breeding lines of spring pebble vetch obtained by diallel crosses were analyzed for valuable economic traits. It has been proven that the degree of phenotypic dominance of F1 hybrids can vary from hp > +1 to hp < -1 depending on the components of the cross. It has been established that in the predominant majority of hybrids, plant height inheritance occurs by types of overdominance and positive dominance. The character of inheritance of the lower pod attachment height is largely determined by the combination of parental components. For seed productivity traits (number of pods, number of seeds, seed weight), heterosis and partial positive dominance were revealed. The weight of 1000 seeds in the predominant majority of hybrids is directed towards small-seededness and inherited by the type of depression, partial negative and partial positive dominance. Conclusions. The results of the study show that the inheritance of feed and seed productivity traits in F1 hybrids of spring pebble vetch is quite complex, the manifestation of which largely depends on the conditions of the study and parental components. Six hybrid combinations were identified, in which the seed productivity traits were inherited by the type of heterosis. For traits suitability for mechanized harvesting, a number of lines were identified in which plant height and lower pod attachment height were inherited by the type of dominance. The identified breeding material can be used in practical breeding to create new varieties of spring pebble vetch with high seed productivity.

Inheritance regularities of economic and valuable traits in selection of sugar beet simple cytoplasmic male sterile hybrids

Aim. To study the influence of parental components of the crossing on the manifestation of the traits “yield of root crops” and “sugar content” in the hybrid progeny for the production of simple CМS hybrids. To create high-yielding simple CМS hybrids as a parent component for the formation of experimental sugar beet hybrids on а CМS basіs. Methods. Field (experiments, phenological observations), laboratory (to determine sugar content), measuring and weighing (to determine the crop structure), statistical (mathematical processing of research results). Results. The nature of the inheritance of productivity traits for the formation of simple CМS sugar beet hybrids has been established. For different combinations of crossings, the value of the inheritance coefficients (h2) of the trait “yield of root crops” from the parent form (O-type line) to the hybrid varied within 0.11–0.71 and 0.52–0.63 from the maternal form (CМS line). The inheritance coefficients of the trait “sugar content” from the parental form were in the range of 0.46–0.53 and 0.42–0.55 from the maternal form. An intermediate type of inheritance was observed for the sugar content in root crops. The best CМS lines and O-type lines have been identified as sources of economic and valuable traits. Seven combining-capable simple CМS hybrids with a high level of basic productivity were created for further use as a maternal component in the selection of sugar beet hybrids on а CМS basіs. Conclusions. A significant influence of the maternal component genotype on the level of yield of root crops of simple CМS hybrids has been established. A regularity has been revealed that the higher the total combining ability of CМS lines, the lower the degree of transfer of the trait “yield of root crops” from the parental form (O-type line) to the hybrid. There is no “mother plant” effect on sugar content in root crops, and an intermediate type of inheritance was observed in hybrids. The use of simple CМS hybrids with an increased level of basic productivity as a maternal component will significantly increase the efficiency of the breeding process for creating competitive sugar beet hybrids on а CМS basіs.

Inclusion of a Parental Component in a Sports-Based HIV Prevention Program for Dominican Youth.

Underprivileged youth in the Dominican Republic (DR) are at high risk of acquiring the human immunodeficiency virus (HIV). Protective parenting practices may inhibit sexual risk-taking. We investigated whether parental involvement in a sports-based HIV prevention program increased self-efficacy to prevent HIV and safe sex behavior among Dominican youth. The study had a quasi-experimental design with repeated measures. N = 90 participants between 13 and 24 years of age participated in the program through two different trainings, UNICA and A Ganar, both of which had an experimental (i.e., program with parental component) and a control (i.e., program without parental component) condition. Self-efficacy to prevent HIV significantly increased among participants in the experimental condition of UNICA. Self-efficacy for safe sex increased among sexually active participants in the experimental condition of A Ganar. Implications for Impact: These findings are important to meet the United Nations' Sustainable Development Goal of good health and wellbeing, as they suggest that parental involvement in sports-based HIV prevention programs can enhance their positive effects for increasing youth's self-efficacy to practice HIV-preventive behaviors. Randomized control trials and longitudinal studies are needed.

Extension of the forming process in the selection of winter common wheat for productivity and quality by using the gene pool of related wheat species within the framework of food security

The formation process in the selection of winter common wheat for productivity and quality has been expanded by using the gene pool of related species. The purpose of this study was to expand the formative process in the selection of Triticum aestivum L. winter type of development with the further obtaining of genotypes with increased adaptability, plant productivity and grain quality through the use of winter common wheat with purple grain, whole grain wheat and Ethiopian wheat in hybridization. In the study, the methods of conducting the examination of plant varieties are used for carrying out phenological observations, morphological studies, evaluation of breeding material according to economic and valuable characteristics. In the creation of new forms, methods of hybridization and individual selection were used, and the TVEL method was used for pollination. The protein and gluten content were determined by infrared spectrometry. Parental components were studied and selected to expand the forming process to obtain productive grains from the main ear, thousand kernel weight, high grain quality, resistant to lodging, shedding of grain, drought-resistant and resistant to fungal pathogens, hybrid forms, specifically as a result of involvement of the source material Triticum aestivum L. and Triticum sphaerococcum Perc. in the hybridization. According to the results of the hybridization of winter common wheat and Ethiopian wheat, it was possible to obtain and breed in F4 forms with a long ear (>10-11 cm), an increased amount of grain from the main ear (>55 pcs.) and a different colour of grain from dark brown to purple, as an indicator of increased anthocyanin content and high antioxidant capacity. The practical value of this study lies in the fact that the research results expand information on the use of winter common wheat in the selection of productivity and quality of other types of wheat: Triticum sphaerococcum, T. aethiop. var. decoloratum, and the developed proposals will allow considering the use of parental components of wheat in research, help improve methods of hybridization and selection of new forms with desirable traits in the system of interspecies crossings

Manifestation of phenotypic dominance in F1 and the degree of transgression in F2 by elements of productivity of the main ear of soft winter wheat

The results of the study of phenotypic dominance in F 1 and the degree of transgression in F2 by elements of productivity: the number and mass of grains and the length of the main ear of soft winter wheat are presented. The selection of parental components for crossing was formed according to the scheme of 7x7 diallel crossings: by productivity (Podolianka, MIP Kniazhna, MIP Yuvileina, MIP Dovira), nutritional direction (Chornobrova, Biliava, Sofivka). In F 1, according to the length of the main spike, heterosis or overdominance was determined in 25 crossing combinations (61.0 %). The highest manifestation of heterosis was found in reciprocal crossings: MIP Kniazhna ↔ Biliava, MIP Yuvileina ↔ Sofivka, MIP Kniazhna ↔ MIP Yuvileina, etc. According to the number of grains in the main spike, heterosis was found in 26 crossing combinations (63.5 %) of MIP Kniazhna ↔ Chornobrova, Chornobrova ↔ MIP Yuvileina, MIP Dovira ↔ MIP Yuvileina, etc. By the mass of grains from the main ear, overdominance was found in 29 crossing combinations (72.5 %) of MIP Kniazhna ↔ Chornobrova, MIP Yuvileina ↔ Biliava, Sofivka ↔ Chornobrova, etc. These groups have the highest value for selection practice. In F 2, most populations signifcantly exceeded parental components, which indicates a signifcant formative process and the possibility of selection. According to the length of the main ear, positive transgression was found in 96.7 % of the hybrid populations. According to the number of grains from the main ear, the degree of positive transgression was determined in 32 hybrid populations (80.9 %). According to the mass of grains from the main ear - in 40 studied populations (97.5 %). A high degree of transgression was characterized by hybrid populations where varieties were used as the maternal form: MIP Kniazhna, MIP Yuvileina, MIP Dovira, Sofivka, Chornobrova, etc. Key words: winter wheat, F1 hybrids, productivity elements, phenotypic dominance, F2 populations, transgression.

Parental Emotion Socialization, Emotion Regulation and Depressive Symptoms in Chinese Adolescence: The Role of Family Cohesion

This study explored the effect of parental emotion socialization behavior (ESB) on depressive symptoms with a focus on the mediating effect of emotion regulation and the moderating role of family cohesion. A total of 236 Chinese adolescents were surveyed and reported on parental ESB, family cohesion, emotion dysregulation, and depressive symptoms. The results indicated that parental ESB toward negative emotions was associated with adolescents’ depressive symptoms, as mediated by emotion dysregulation. Moreover, higher levels of family cohesion both enhanced the negative relationships between supportive ESB toward anger/sadness and emotion dysregulation and strengthened the positive relationship between non-supportive parental ESB toward sadness and emotion dysregulation. These findings clarify the interactive effects of multiple components of emotional parenting, reveal the double-edged effects of family cohesion in the association between parental ESB and depressive symptoms in adolescents, and highlight the importance of evaluating the family emotional context in research and clinical interventions.

Parental Socialization and Adjustment Components in Adolescents and Middle-Aged Adults: How are They Related?

Classic studies mainly of European-American families broadly identify the benefits of parental strictness combined with parental warmth. However, current research tends to identify parental warmth as positive for adjustment, even without parental strictness. In addition, less is known about the relationship between parenting and adjustment beyond adolescence. The present study examined warmth and strictness and its relationship with self, sexism, and stimulation values. Self-esteem, academic-professional self-concept, benevolent sexism, and stimulation values were used to capture adjustment. Participants (n = 1125) were adolescents and adult children of middle-age from Spain. The statistical analyses used were correlation analysis and multiple linear regression. In general, the relationship between parenting and adjustment was found to have a similar pattern for adolescent and middle-aged adult children, although more marked in adolescents. Parental warmth and strictness were predictors of adjustment, but in a different direction. Specifically, parental warmth positively predicted academic-professional self-concept and self-esteem, whereas parental strictness was detrimental as a predictor of higher benevolent sexism. Overall, the present findings suggest that an effective socialization during the socialization years and even beyond can be positively predicted by parental warmth, whereas parental strictness might be unnecessary or even detrimental.
