    In search of these answers, the investigator immersed herself into this student microcosm for the fall 1999 semester. The data were collected through extensive classroom observation, occasional reviewing of the instructor\u27s materials and students\u27 writing, and finally conducting two focus groups in the beginning the following semester where the students were given an opportunity to describe their experiences in their own words. The findings can be summarized in the following way. Taking classes together, living in the same residence hall, having a network and support of friends, having a peer mentor and faculty and staff members available, and experiencing various cultures firsthand made the transition for both international and U.S. students easier, more interesting and richer in an educational sense.This qualitative study attempted to evaluate a cross-cultural learning community at Iowa State University. The need for this study was dictated by a variety of factors. First, it was a response to the call for assessment of learning communities. Practitioners need to know in what ways learning communities succeed and in what ways they do not. Moreover, they need to know how students\u27 experiences in learning communities can be improved. Similarly, the existing research reports that learning communities enhance educational reforms, and thus make the academy more responsive to societal needs. This study illustrated how a specific learning community at ISU responds to changes in the academy as well as in the society. Second, the need to study a cross-cultural learning community was determined by its unique and innovative nature. Because cross-cultural learning communities of this kind are virtually nonexistent, knowing what benefits they have to offer to their participants is of great importance. The investigator sought to answer three research questions: a) What role did this learning community play in the students\u27 transition to university life? b) Did the cross-cultural learning community enhance cross-cultural awareness and understanding? If yes, in what ways? c) How did the students perceive this learning community experience in general

    На сьогоднішній день активно розвиваються багато спортивних дисципліни, функціональна ба-за яких, на жаль, застаріла в зв'язку з політичною обстановкою в нашій країні в дев'яностих роках. До числа таких дисциплін поряд з лижними гонками, легкою атлетикою, водними виду-ми спорту відноситься і велоспорт. Олімпійські ігри, конки на треку, маунтінбайк, даунхіл і інші напрямки вимагають будівництва спеціальних споруд, пристрої та благоустрій трас, прокладки маршрутів, розвитку транспортної мережі та багато чого іншого. Особливо гостро стоїть питання з трековими гонкамиToday, many sports are actively developing, the functional base of which, unfortunately, is outdated due to the political situation in our country in the nineties. Among such disciplines, along with cross-country skiing, athletics, water sports, is cycling. The Olympic Games, track skating, mountain biking, downhill and other areas require the construction of special structures, devices and improvement of tracks, laying routes, development of the transport network and much more. The issue of track racing is especially acuteЗМІСТ ВСТУП РОЗДІЛ 1. Архітектурно-будівельна частина 1.1. Природно-кліматичні умови будівництва 1.2 Генеральний план 1.3.

    The present study investigated the effect of chelated forms of microfertilizers applied in the tillering-shooting phase on the background of mineral nutrition (N90P90K90) with the phased application of nitrogen in stages IV and VII of organogenesis on the seed productivity and the sowing qualities of seeds of the winter wheat variety Benefis. The studies were conducted according to the generally accepted methods. The processing and synthesis of research results were performed using Microsoft Excel. The obtained data were processed by the method of dis¬persive and correlation analysis. The experimental results confirm that the use of chelated forms of microfertilizers contributes to winter wheat seed productivity. Grain yield increases by 0.12 -0.34 t/ha, the yield of conditioned seeds – by 2-6%, seed yield increases by 0.20-0.71 t/ha, the coefficient of seed reproduction – by 0.8-2.9 units, the mass of 1000 seeds – by 0.3-1.8 g. The optimal level of plant nutrition at the expense of better assimilation of trace elements has a positive effect on the formation of sowing qualities of winter wheat, increasing the mass of 1000 seeds by 0.6-2.8 g, seed germination energy – by 1.8-6.3%, laboratory germination – by 0.8-3 0%. The highest ef¬ficiency was obtained with the application of the complex microfertilizers Orakul copper chelate (1-2 l/ha), Orakul biocobalt (0.15-0.20 l/ha) and Orakul multicomplex (1-2 l/ha)

    Biological mechanisms of regulation of winter wheat productivity in the conditions of the Western Forest-Steppe of Ukraine

    The western Forest-Steppe of Ukraine belongs to the area of risky seed production because of the low natural fertility of soils (estimated by 33 points) and a large amount of rainfall (680–760 mm), which causes every 2–3 years to obtain low-yielding seeds. Scientific studies indicate an increase in the productivity of plants of various cultures through the use of growth stimulants and bacterial preparations containing a balanced complex of biologically active substances, which contribute to the activation of the basic life processes in plants and the root zone. The search and selection of highly effective and competitive biological products in various soil and climatic zones remains an urgent issue. Our studies were aimed at assessing the effectiveness of pre-sowing treatment with Vympel-K growth stimulator applied separately and in combination with the bacterial preparations Diazophyte (based on the nitrogen fixing bacterium Agrobacterium radiobacter) and Polymyxobacterin (based on the phosphorus-mobilizing bacterium Paenibacillus polymyxa) for the yield and sowing qualities of winter wheat (Zolotokolosa variety). For comparison, a variant with water seed treatment and a variant with Vitavax disinfectant dressing were also evaluated. It was established that with the joint use of the studied preparations, seed germination rates are higher by 4.8%, the percent of overwintered plants – by 5.5%, seed yield – by 0.54 t / ha, the mass of 1000 seeds – by 2.1 g, germination energy of collected seed – by 2.1%, laboratory germination – by 2.2%. The increasing of the genetic potential of the varieties that are introduced into production due to the elements of biologized growing technology allows to regulate the growth and reproduction processes and adjust the nutritional conditions of winter wheat, since biological preparations are environmentally friendly and their low cost helps to reduce the cost of produced seeds

    Specific manifestation of enzymomycotic depletion of grain on crop losses

    Get PDF
    Background. Enzymomycotic depletion of grain leads to a significant decrease in the dry matter mass of the grain, as the intensity of respiration increases, protein substances break down, enzymes (in particular, α-amylase) pass from the adsorbed form to the water-soluble one, and their activity increases sharply. One of the consequences of this is the intensive amylolysis of starch, which means a significant deterioration in the technological indicators of the quality of grain and seeds. Materials and Methods. This study gives a thorough description of the process of enzymomycotic depletion of grain of soft winter wheat (Triticum aestivum L.), sowing rye (Secale cereale L.), winter triticale (Triticosecale Witt.) depending on abiotic factors and the sources of resistance to ear diseases 4, 8, 12 days after the onset of full ripeness in the conditions of the western forest-steppe of Ukraine (2019–2021). Research methods – general scientific, field, measurement and weight, mathematical and statistical. Results and Discussion. According to the obtained results, the dependence of enzymomycotic depletion of grain on abiotic factors was established. The development of ear diseases depended both on weather factors and on the ecological plasticity of the cultivar. The highest percentage of the distribution of ear sepsoria was observed on the 12th day after the onset of full ripeness: wheat – 3.3 %, rye – 2.4 %, triticale – 1.9 %, fusarium, respectively 2.4 %, 1.9 %, 1 %, 8 %. The loss of dry matter in the weight of 1000 grains depended on the ecotype of the cultivar and the duration of the grain stan­ding time 4, 8, and 12 days after full ripeness. Conclusion. The following cultivars were most resistant to EMDG: Oberih Myronivsky (wheat), Kobza (rye), Obrij Myronivsky (triticale); their base seed production profitability rates being 75.1 %, 116.6 %, and 146.8 %, respectively. The results of the study can be used in the selection of varieties of winter grain crops resistant to enzymomycotic grain depletion for the western forest-steppe and Polissya zones of Ukraine, where breeding work on these crops is not carried out and agricultural producers purchase seeds of new varieties from the originating institutions of the central forest-steppe to introduce them into production

    Building a culture of engagement at a research centre for childhood disability

    Get PDF
    BACKGROUND: Engaging patients and family members as partners in research studies has become a widespread practice in healthcare. However, relatively little has been documented about what happens after the research study ends. For example, is patient and family engagement embedded in the wider infrastructure of organizations, and if so how? What are the long-term effects of engaging parents on research teams on the culture of how research is conducted? This study seeks to address these two gaps by examining how a culture of family engagement has been built over time at CanChild Centre for Childhood Disability Research at McMaster University in Ontario, Canada. METHODS: This study is based on ethnographic research methodology and combines elements of organizational ethnography, interviews, and collaborative auto-ethnography with parent partners, researchers, staff, and trainees. RESULTS: Since the inception of CanChild Centre for Childhood Disability Research at McMaster University in 1989, parents have been involved in research studies. Over time, this involvement evolved from being consulted on research studies to undertaking decision-making roles as partners and most recently as co-principal investigators. A growing infrastructure fosters a community of engagement that goes beyond the individual research study, and often beyond CanChild. This infrastructure consists of training, knowledge mobilization and social networking. In addition, the "softer" building blocks of CanChild's culture of engagement are an openness to learning from others, a commitment to relationship building, and a drive to grow and improve. These values are espoused by the leadership and are instilled in the next generation of researchers to inform both research and clinical work. While some challenges should be acknowledged when researchers and family partners work together on research studies, we identify a number of strategies that we have used in our studies to foster authentic and meaningful family-researcher partnerships. CONCLUSION: Engaging patients and families as partners in research constitutes a culture shift in health research, whereby studies about patients and families are carried out with them. Developing a community of engagement that transcends an individual research study is a step towards creating a culture of research that is truly shaped by the people about whom the research is being done
