In this work the author deals with the description of the most important stages of construction technology. More attention is given to drátkobetonové floors and steps of construction steel buildings. Finally he was taken into account in the way of material resources and ensuring the continuity of time stages.

The purpose of this study was to construct portrayals of teachers7 work conceptions in various career stages from the stories they told and the metaphors they used to describe the ways in which teachers learned about their work. Specifically, the study included preservice teachers, first-year teachers, third-year teachers, and teachers with more than four years of teaching experience at the elementary and secondary school levels. Thirty-five elementary and secondary school teachers from the North-Central area of Texas participated in this study (nineteen inservice and sixteen preservice teachers). Qualitative techniques were employed to collect data. The preservice teachers filled out a questionnaire and wrote short stories about their preconceptions of their first year of teaching. Inservice teachers were interviewed using a short questionnaire and a long interview schedule. Nine inservice teachers participated in a storytelling workshop/focus group session. Group stories based on predetermined scenarios were constructed, tape-recorded and transcribed. The focus group session was videotaped and transcribed. Fifteen categories emerged from the analysis of the data: cyclical, ritualized, hierarchical, reciprocal, developmental, experiential, reflective, cumulative, body of knowledge, folkloric, individualized/personalized, order/control/manage, disciplinarian, facilitative, and replicative. These categories represent a summary of the constructs, images, contextual maps and metaphors held by these teachers to describe their enculturation process. The descriptive categories developed in this study offer teacher educators, supervisors and teachers a basis for understanding the culture of teachers. The storytelling technigues used in this study provide a means by which teachers and teacher-related personnel can generate further information about the enculturation process that can be applied to recruitment, orientation/ induction programming, reflective teacher preparation and change strategies.

As a growing population ventures forth into the 21st century, people are living longer than ever before. Recent statistics indicate an ever-increasing adult population. With a larger and older population, communities will find themselves striving to ensure a high quality of life for these persons. Individuals, as well, will find themselves seeking out activities that will keep them actively involved and engaged in their post-retirement years. The purpose of this biographical study was to explore the motivations for lifelong learning and engagement in the life of Evelyn McQueen Cook, a seventy-five year-old resident of Johnson County, Tennessee. Her life is presented in the context of an educational narrative and analyzed within the contextual and theoretical framework of lifelong learning. Data were collected through a series of interviews with the subject. Interviews were recorded and tapes of the interviews were transcribed. Using interpretative analysis, data were examined to determine themes. Further information was collected through photographs, postcards, letters, and certificates. Findings were presented thematically within a chronological context. The importance of family, formal educational opportunities, the influence of teachers, the opportunity to travel extensively, self-directed learning, cultural experiences, career choices, and involvement in community all emerged as strong motivations for pursuit and engagement in learning opportunities over the span of her life. Financial concerns, lack of confidence, ability, or interest, long-held beliefs or feelings, loneliness and a sense of isolation, gender and being an only child, and age all emerged as distracters or barriers to learning. Recommendations included the need to provide adults more opportunities that allowed them to reflect upon their educational experiences, both formal and informal. Specific recommendations were noted for predominately rural communities. A need for further educational biographies was also suggested.

The purpose of this study is to collect information documenting Utah technology education teachers' acceptance of an emphasis on engineering content in technology education. The Stages of Concern Questionnaire (SoCQ) was used to determine the level of acceptance of this change. It was found that a majority of technology and education teachers are more concerned about other unidentified tasks, activities or initiatives than they are about the addition of engineering content to their classes. They were also shown to be concerned with being able to organize, manage, and schedule the change effectively and were found to be least concerned about evaluating student outcomes including performance and competencies. Utah teachers were polarized with respect to collaborating and coordinating with others with regards to engineering.

The application of digital elements to traditional playgrounds can enhance children’s outdoor play and counteract the growing trend of sedentary activities. This work reports the implementation and evaluation of a playground installation which looks at sound as the modality that can provide new and engaging play experiences. The design of this system follows an open-ended approach that let the children create their own emerging game goals and rules. The sound design is first tested in a lab setting and later on in a Swedish preschool, with a particular focus on the stages of play (invitation, exploration, and immersion). 38 children between 2 and 6 years old participated in a field study that lasted for three days. Children’s engagement over time was quantified and field notes were taken during the whole evaluation. None of the children between 2 and 3 years old reached the immersion stage. On the other hand, children between 4 and 6 years old created their own rules showing parallel and collaborative play and, in some occasions, solitary play. The sound modality chosen proved to be effective to encourage children’s play in a first place. In a longer engagement perspective, the soundscape partly supported an immersive play. The selection of the sounds to be integrated in the system demonstrated to be as fundamental as the physical appearance of the playground installation. The results of this study show how the visual and auditory modalities can be effective in an open-ended interactive playground and report the limitations of this design. / Additionen av digitala element till traditionella lekplatser kan förstärka barns utomhuslek och motverka den växande trenden av stillasittande aktiviteter. Detta arbete beskriver genomförandet och utvärderingen av en lekplatsinstallation med ljud i fokus som den modalitet som kan tillhandahålla nya och engagerande lekupplevelser. Utformningen av denna lekplatsinstallation skedde ur ett fri lek-perspektiv där barn skapar egna mål och regler till sin lek. Ljuddesignen är först testad i en laboratoriemiljö och senare i en svensk förskola, med särskilt fokus på lekfaserna (invit-fasen, utforskande-fasen och uppslukad-fasen). 38 barn mellan 2 och 6 år deltog in en fältstudie som varade i tre dagar. Barns engagemang över tid kvantifierades och noteringar togs under hela utvärderingen. Inga av barnen mellan 2 och 3 år nådde uppslukad-fasen. Å andra sidan skapade barn mellan 4 och 6 år egna regler som visar på parallell och samspelslek och i några fall ensamlek. Den valda ljudmodaliteten visade sig vara effektiv för att uppmuntra barns lek till en början. På längre sikt understödde ljudlandskapet delvis lek av uppslukad karaktär. Valet av ljud integrerat i systemet visade sig vara lika fundamental som den fysiska uppenbarelsen av lekplatsinstallationen. Resultaten av denna studie visar hur de visuella och auditoriska modaliteterna effektivt kan vara designade i en interaktiv lekplats för öppen lek, och begränsningarna av denna design rapporteras.

Pythium diseases are common in the greenhouse production of tobacco transplants and can cause up to 70% seedling loss in hydroponic (float-bed) greenhouses. However, the symptoms and consequences of Pythium diseases are often variable among these greenhouses. A tobacco transplant greenhouse survey was conducted in 2017 in order to investigate the sources of this variability, especially the composition and distribution of Pythium communities within greenhouses. The survey revealed twelve Pythium species. Approximately 80% of the surveyed greenhouses harbored Pythium in at least one of four sites within the greenhouse, including the center walkway, weeds, but especially bay water and tobacco seedlings. Pythium dissotocum, followed by P. myriotylum, were the most common species. Pythium myriotylum, P. coloratum, and P. dissotocum were aggressive pathogens that suppressed seed germination and caused root rot, stunting, foliar chlorosis, and death of tobacco seedlings. Pythium aristosporum, P. porphyrae, P. torulosum, P. inflatum, P. irregulare, P. catenulatum, and a different isolate of P. dissotocum, were weak pathogens, causing root symptoms without affecting the upper part of tobacco seedlings. Pythium adhaerens, P. attrantheridium, and P. pectinolyticum did not affect tobacco seeds or seedlings. The consequences of Pythium infection were more likely to be severe when they occurred during seed germination than at seedling emergence, or after plant stem elongation when seedling roots had started to grow into underlying nutrient solutions, depending on the species of Pythium. High and low variation was observed among isolates of P. dissotocum and P. myriotylum, respectively. Pythium myriotylum co-existed with multiple other Pythium or oomycete species in the same environments within tobacco greenhouses, and significant in vitro and/or in vivo interactions between P. myriotylum and some naturally co-existing species were revealed. Pythium porphyrae may have the potential to protect tobacco seeds and seedlings from P. myriotylum infection. Greenhouse Pythium control trials identified ethaboxam, mefenoxam, and copper ionization as potentially promising alternatives to etridiazole for Pythium disease management in tobacco transplant production. The outcomes of this project provide useful new information to better understand the composition, distribution, and diversity of Pythium communities in tobacco transplant greenhouses and to improve Pythium disease management for tobacco transplant production. / Doctor of Philosophy / Pythium diseases are common in tobacco transplant production and can cause up to 70% seedling losses in hydroponic (float-bed) tobacco transplant greenhouses. However, little is known about the composition and distribution of Pythium communities in tobacco transplant greenhouses. This project began with a tobacco transplant greenhouse survey, in which 12 Pythium species were recovered from center walkways, weeds, greenhouse bay water, and tobacco seedlings. Pythium dissotocum and P. myriotylum were the two types (species) of Pythium most commonly found in the survey. Pythium myriotylum, P. coloratum, and P. dissotocum were aggressive pathogens that suppressed seed germination and caused root rot, stunting, foliar chlorosis, and death of tobacco seedlings. Pythium aristosporum, P. porphyrae, P. torulosum, P. inflatum, P. irregulare, P. catenulatum, and an isolate of P. dissotocum, were weak pathogens causing root symptoms without affecting the upper part of tobacco seedlings. Pythium adhaerens, P. attrantheridium, and P. pectinolyticum did not affect tobacco seeds or seedlings. The symptoms caused by infection by Pythium species differed among host (tobacco) growth stages, except for the most aggressive species, P. myriotylum. High levels of variation were observed among isolates of P. dissotocum, in terms of vegetative growth rate (on V8 agar media) and aggressiveness on tobacco seed and seedlings. Pythium myriotylum was found to co-exist with multiple other Pythium or oomycete species (neighbor isolates) in the same environments within tobacco greenhouses. Significant interactions between P. myriotylum and some neighbor isolates were revealed, and these interactions significantly affect the consequences of P. myriotylum infection of tobacco seeds. Greenhouse Pythium control trials identified two chemical water treatments (ethaboxam and mefenoxam), and a non-chemical water treatment (copper ionization) as potentially promising alternatives to the current standard Pythium control (etridiazole) for Pythium disease management in tobacco transplant production. The outcomes of this project provide useful new information to both better understand the composition, distribution, and diversity of Pythium communities in tobacco transplant greenhouses and to improve Pythium disease management for tobacco transplant production.

In the face of unprecedented anthropogenic change, we increasingly turn to emergent technologies and extensive data sets for solutions that complement much needed systemic changes in our societies. These technological solutions, however, must be approached with care. We must recognize and address biases in the way data has been accumulated. In demographic studies, dormant life stages, such as seed banks, and other cryptic factors have often been neglected. The potential consequences of these omissions have been extensively described in the literature. In the first chapter, I analyze patterns of seed bank omissions in demographic models, finding unjustified omissions are widespread across ecoregions, growth forms, and taxonomic groups. More importantly, studies with longer duration and accounting for a greater range of conditions were less likely to neglect the seed bank. Unfortunately, most demographic studies are conducted for relatively short periods and are limited to one or a few sites. In addition, modeling tools often focus on mean behavior and do not properly characterize variability. In the second chapter, I explore the use of Bayesian generalized linear mixed models to characterize vital rates and compare their variation across growing conditions. Using wild and translocated populations of Dicerandra christmanii,this study tests the ability of this approach to evaluate early translocation success and site suitability.In chapter 3, I expand the demographic analysis of Dicerandra christmaniiand provide an example of the use of Bayesian-fitted Integral Projection Models (IPMs) to combine data sources and incorporate seed dynamics into demographic models. By propagating uncertainty from vital rates to derived population metrics, this study illustrates the consequences of accounting for the seed bank stage and site condition to our assessment of population viability. In the final part of this work, I present potential routes to expand field and modeling tools to help address the inclusion of dormant and cryptic life stages into demographic studies. Among these, I recommend exploring more complex sampling schemes, informed priors, and expanded IPMs.

The thesis focuses on the integration of sustainability in the early stages of startups by developing a new framework. Given the resource constraints and focus on viability, it might be difficult for startups to consider sustainability at these early stages. A literature review revealed a lack of information on this subject. The research investigates the sustainability-related challenges startups face, identifies factors for sustainable business models using expert interviews and literature review. Due to the lack of information related to sustainable early stages start-ups, the author analyses basic principles related to start-ups and sustainability. The author looks into holistic approach to sustainability since a fragmental approach to sustainability risks harming the ecosystem while improving some metrics without systemic overview. Life-centred design is an emerging design approach that focuses on the well-being of all life forms and the health of our planet, thus making a shift from just human-centred design. The life-centred design was taken into consideration since it covers different aspects of sustainability as well as ethics and provides practical guidance for the designing process. Based on literature review and expert interviews the framework was formulated. The developed solution was tested with three early-stage startups, providing practical insights. The author analyses the findings and concludes that start-ups which have sustainability as a core value proposition are already sustainable and their sustainable impacts potentially scales with their product growth. At the same time for these types of start-ups it’s vital to consider additional value for the customer apart from sustainable value. For the start-ups with core value not directly related to sustainability, the sustainability can be embedded within a lean approach and aligning sustainability with their business goals if it doesn't require sacrificing limited resources such as money. Finally, the author suggests tools that raise awareness of participants and can be useful for holistic picture, based on findings during the workshop.
