Представлены результаты изучения аллелопатической активности Quercus robur L., Acer platanoides L., Ulmus glabra Huds методом биотестирования. Выявлены различия воздействия аллелохимикатов на прорастание семян и развитие проростков тест-объекта в контролируемых условиях. Показана корреляция концентрации водных вытяжек листового опада и аллелопатического эффекта, оказываемого ими, которая подтверждена анализом функции средней. Here we present the results of studying the allelopathic activity of Quercus robur L., Acer platanoides L., Ulmus glabra Huds by biotesting. We revealed differences in the effect of allelochemicals on seed germination and the development of seedlings of the test object under controlled conditions. The correlation of the concentration of aqueous extracts of leaf litter and the allelopathic effect exerted by them is shown. The mentioned correlation is confirmed by the analysis of the average function.

Abstract. This study used a longitudinal data set of 5,672 adults followed for 50 years to determine the factors that influence adult trait Openness-to-Experience. In a large, nationally representative sample in the UK (the National Child Development Study), data were collected at birth, in childhood (age 11), adolescence (age 16), and adulthood (ages 33, 42, and 50) to examine the effects of family social background, childhood intelligence, school motivation during adolescence, education, and occupation on the personality trait Openness assessed at age 50 years. Structural equation modeling showed that parental social status, childhood intelligence, school motivation, education, and occupation all had modest, but direct, effects on trait Openness, among which childhood intelligence was the strongest predictor. Gender was not significantly associated with trait Openness. Limitations and implications of the study are discussed.

Three personal reflections provided by doctoral students of the Michigan School of Professional Psychology (Farmington Hills, Michigan) address identification of individual perspectives on the tragic events surrounding Trayvon Martin’s death. The historical ramifications of a culture-in-context and the way civil rights, racism, and community traumatization play a role in the social construction of criminals are explored. A justice orientation is applied to both the community and the individual via internal reflection about the unique individual and collective roles social justice plays in the outcome of these events. Finally, the personal and professional responses of a practitioner who is also a mother of minority young men brings to light the need to educate against stereotypes, assist a community to heal, and simultaneously manage the direct effects of such events on youth in society. In all three essays, common themes of community and growth are addressed from varying viewpoints. As worlds collided, a historical division has given rise to a present unity geared toward breaking the cycle of violence and trauma. The authors plead that if there is no other service in the name of this tragedy, let it at least contribute to the actualization of a society toward growth and healing.
