Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Ornamental plants in general are highly susceptive to water deficiency, principally to the elevated soil water level variation that effects at a precarious and uneven final product development. The study was conducted on greenhouse at the Universidade Federal de Santa Maria, RS. It aimed to observe if rice husk ash substrate offers limitation to the pot cultivation of the specie, to evaluate de the root development under different water availability levels and to analyze the effects on the flower stem qualities and pack yields in two different cultivation periods. The studied specie was Gypsophila paniculata Golan . The seedlings were attained from donor plants at the Floriculture Sector of the Phytotecny Department of UFSM. The experiment was conducted in flexible polyethylene pots with 18 liters of capacity, filled with rice husk ash carbonized on a rice drier mill and kept on 100%, 80%, 60% and 40% of the limit water retention capacity of the pot. The humidity was kept by the weighing method, three times a week (Monday, Wednesday and Friday) the pots were weighted on a decimal precision scale and the difference of the pot weight was added with water to attain the limit established weights to each treatment on the two cultivation periods. The comparison of the production components among the treatments was performed through the variance analyses (ANOVA) significance level of 5% and the regression analyses, because the treatments are quantitative. The comparison between the periods of cultivation was obtained throughout the Tukey Test at the mistake significance level. The results showed that the fine granulometry of the rice husk ash is not a limitation to the cultivation of gypsophila in 18 liters pots. The water consume is higher at the production cycle of spring/summer and it rises with increasing of the water availability, independently the period. The water availability changes the roots spatial distribution in the pot, also changes the length and the dry mass. The commercial quality of the produced stems is not affected importantly by the humidity levels of the substrate or the cultivation cycle. The yield of packs is higher with above 60 % end 80%, humidity for the fall/winter cultivation. However, the 80% of availability provides the best yield. / As plantas ornamentais, de forma geral, são bastante susceptíveis às deficiências hídricas, principalmente às grandes variações do nível de água no solo, refletindo-se num desenvolvimento precário e desuniforme do produto final. O presente trabalho foi realizado em casa de vegetação da Universidade Federal de Santa Maria, RS. Teve como objetivo observar se o substrato casca de arroz carbonizada oferece limitação para o cultivo da espécie em vasos, avaliar o desenvolvimento radicular sob variados níveis de disponibilidade hídrica e analisar sua resposta sob qualidade das hastes florais, e a produtividade de maços, em duas épocas de cultivo. A espécie utilizada foi Gypsophila paniculata variedade Golan . As mudas utilizadas neste experimento foram obtidas a partir de plantas matrizes existentes no Setor de Floricultura do Departamento de Fitotecnia, da UFSM. O ensaio foi conduzido em vasos com capacidade para 18 litros de polietileno flexível, os quais foram preenchidos com substrato de casca de arroz carbonizada, e mantidos em 100%, 80%, 60% e 40% do limite da capacidade de retenção hídrica do vaso. A manutenção da umidade foi realizada pelo método das pesagens, onde três vezes por semana (segunda, quarta e sexta) os vasos eram pesados em balança com precisão decimal, a diferença de peso do vaso, era complementada com água até atingir os limites de peso estipulados para cada tratamento nos dois ciclos de cultivo. O delineamento experimental foi inteiramente casualizado composto por quatro tratamentos e 10 repetições. A comparação dos componentes de produção entre os tratamentos aplicados para os distintos ciclos foi realizada por análise de variância (ANOVA) ao nível de 5% de significância e regressão visto que são tratamentos qualitativos. A comparação entre os ciclos foi feita pelo Teste de Tukey ao nível de 5% de significância de erro. Os resultados obtidos mostram que o tipo de granulometria fina do substrato casca de arroz carbonizada não oferece limitação ao cultivo de gipsofila em vasos de 18 litros. O consumo de água é maior no ciclo de produção correspondente a época primavera/verão e aumenta à medida que a disponibilidade se eleva, independente de época. A disponibilidade hídrica altera a distribuição espacial das raízes no vaso assim como e comprimento e a matéria seca. A qualidade comercial das hastes produzidas não é afetada de modo importante pelos níveis de umidade do substrato ou ciclo de cultivo. A produtividade de maços por m2 é superior com níveis de umidade entre 60 e 80% para os dois ciclos. A disponibilidade de 80% foi aquela que proporcionou a melhor rentabilidade.

The thesis examines the Kenya's cut-flower industry in the wider context of global commodity networks. The Kenya's floriculture sector as a part of these networks has been influenced by notions of environmental and social responsibility in the past two decades. The first part of the thesis describes floriculture in Kenya and the cut flower supply chain. The second half analyses current ethical trading practice in the flower industry in Kenya. In this respect codes of conduct which embody notions of responsible business in practice are discussed here. In view of the fact that codes can't guarantee adequate working conditions to flower farm workers in many cases the thesis tries to explain why this concept of ethical trade failed.

This diploma thesis describes the issue of teaching Peace Education in a Montessori School. It comprehensively characterises the concept of Peace Education, mapping the content of lessons and materials which form part of the prepared environment of a Montessori class. I was interested in the inclusion of Peace Education in the Montessori Curriculum because it has an important role in education as Marie Montessori believed that peace begins in children. For the elaboration of the practical part, I chose action research which took place in Orange Class at Duhovka Elementary School - Prague, where I have been working as a class teacher since September 2020. The research was conducted in a mixed age class of Gd 1-3 students aged 6-9 years. I focused mainly on trying out the lessons with my class having created the materials for the prepared environment. In conclusion, I will evaluate the contribution of Peace Education for the class team and the changes of dynamics within the students in terms of respecting others. In addition, I will also reflect on the lessons and write recommendations for teachers who would like to use them.

South American plant Clusia blattophila, growing on Nouraghes of French Guiana, produces relatively large amounts of volatile substances in the fragrance of its flowers. C. blattophila is dioecious plant with different flowering time of monosex flowers Male flowers bloom for one night, while female flowers bloom two nights. The volatiles were adsorbed to the adsorbent and washed out with hexane with internal standard. Analysis was performed by two-dimensional gas chromatography with mass spectrometric detection. The aim of my thesis was to determine the qualitative and quantitative characteristics of flower scents of both sexes. I also studied, whether there are differences in production of the major fragrance component, acetoin, during the first night of blooming. The flower fragrance is complex blend of volatiles. In total, 43 different chemicals were identified. Among them were monoterpenes (α-pinene, camphene, β-pinene, myrcene, limonene, (E)-β-ocimene, camphor) sesquiterpenes (α-copaene, β-caryophyllene, cis-α-bergamotene, trans-α-bergamotene, aromadendrene, (E,E)-α-farnesene, δ-cadinene), aldehydes (1-pentanal, 1-hexanal, 1-octanal, n-decanal), also four ketones (acetoin and its dimer, 2,5-hexanedione, 6-methylhept-5-en-2-one), alcohol butane-2,3-diol, carboxylic acid 2-methylpropanoic,...

The aim of the presented dissertation thesis is to find out the answer for the question of how it is possible to process and evaluate by computer methods of data coming from psychotherapy sessions using the method of Guided Affective Imagery. The Guided Affective Imagery is a relatively young psychotherapy approach based on the European tradition of psychodynamic psychology which presumes that in assignment relatively indefinite motive in imagination during day dream comes to manifestation of a client's unconsciousness contents and conflicts, defensive mechanisms, resistance, motives and fantasy. The biofeedback device by which was the rate of heartbeat used during the whole session and computer programs for quantitative text analysis were used for verifying the usage of computer methods for the sessions' analysis. The quantitative text analysis focused on identification of primarily and secondarily measure of the item process in the preliminary part of a session, during the phase of imagination and at the final part of the session by two code systems. In a certain way the results indicate complementary progress of changes in the primary and secondary process when the highest representation of secondary process expressions was identified in the introductory part of the session whereas the highest...

Phenotypic plasticity plays an important role in organisms’ adaptability to environmental change such as global warming caused by greenhouse-gas emissions. One plastic response to increased temperatures is for organisms to shift their phenology. It is of great concern that the phenologies of interacting species, such as plants and pollinators, may be shifting at different rates, causing temporal mismatches, which for plants can lead to unsuccessful reproduction. The “reproductive assurance hypothesis” states that plants capable of self-pollination should be under high selection to employ this as their main reproductive strategy in the event of pollinator scarcity to ensure reproduction, and consequently invest less in attracting pollinators. This study examines how soil warming in the Hengill geothermal area in Iceland affects the flowering phenology, reproductive strategy and investment in attractiveness to pollinators in the self-compatible herb Cerastium fontanum (Caryophyllaceae), when grown in a common garden in Stockholm, Sweden. Previous research showed that C. fontanum from warmed soils flowered earlier in situ than plants from colder soils, and later when grown in a common environment. In this study, C. fontanum plants collected along a temperature gradient followed the same counter-gradient pattern, where plants from warmer soils flowered later than plants from colder soils. Soil temperature at site of origin positively affected flower number but had no effect on flower size, seed production from autogamous self-pollination or visitation rate. Based on my findings it does not appear that C. fontanum, despite having an earlier flowering phenology in situ, is under any selection to alter its reproductive strategy or investment in attractiveness to pollinators when grown in a common temperature, and therefore it seems unlikely that plants are experiencing a temporal mismatch with insect pollinators. However, it would be worthwhile to conduct a similar experiment in Iceland to better understand how an earlier flowering affects pollination systems.

En la actualidad, se evidencia un incremento de residuos sólidos en Lima Metropolitana (INEI, 2019). Según el informe de INEI, los distritos que generan mayor cantidad de residuos son Santiago de Surco, Miraflores, San Miguel y La Molina. Por otro lado, la pandemia generada por el COVID-19 ha generado un cambio en los hábitos de compras del consumidor y esto se ve reflejado debido a que existe un incremento en las compras a través del e-commerce, con la finalidad de evitar los contagios los consumidores prefieren comprar todo tipo de artículos desde la comodidad de su hogar. Tomando en consideración ambas variables, nace la idea de crear un proyecto de florería ecoamigable con la modalidad de delivery. Para ello, se hará uso de productos eco-amigables los cuales permitirán reducir el consumo de plásticos y otros materiales dañinos para el medio ambiente comparado a los arreglos florales tradicionales ofrecidos en las florerías. De esta manera, se busca generar conciencia en los consumidores respecto a la importancia de cuidar el medio ambiente. Por lo tanto, se realizó una investigación cualitativa para determinar la frecuencia y aceptación de este proyecto en las zonas 6 y 7 de Lima Metropolitana. Además, se realizó un análisis financiero a través del cual se obtuvieron indicadores de rentabilidad favorables, los cuales avalan la viabilidad y rentabilidad de poner en marcha “Costumbres Latinas” un proyecto que ofrecerá la posibilidad de reducir la contaminación ambiental a través del uso de productos orgánicos y el reciclaje de residuos sólidos. / Currently, there is an increase in solid waste in Metropolitan Lima (INEI, 2019). According to the INEI report, the districts that generate the greatest amount of waste are Santiago de Surco, Miraflores, San Miguel and La Molina. On the other hand, the pandemic generated by COVID-19 has generated a change in consumer shopping habits and this is reflected due to the fact that there is an increase in purchases through e-commerce, in order to avoid contagions consumers, prefer to buy all kinds of items from the comfort of their home. Taking both variables into consideration, the idea of ​​creating an eco-friendly florist project with the delivery modality was born. For this, eco-friendly products will be used which will reduce the consumption of plastics and other materials that are harmful to the environment compared to the traditional flower arrangements offered in flower shops. In this way, it seeks to generate awareness in consumers regarding the importance of caring for the environment. Therefore, a qualitative investigation was carried out to determine the frequency and acceptance of this project in zones 6 and 7 of Metropolitan Lima. In addition, a financial analysis was carried out through which favorable profitability indicators were obtained, which endorse the viability and profitability of launching "Latin Customs" a project that will offer the possibility of reducing environmental pollution using products. organic and solid waste recycling. / Trabajo de investigación

Indiana University-Purdue University Indianapolis (IUPUI) / Founded in 1876 by a small group of young women who resolved to deliver bouquets to patients in the City Hospital, the Indianapolis Flower Mission quickly grew to become one of the most respected philanthropic organizations in the city. During its almost one hundred and twenty year history, the Indianapolis Flower Mission created lasting institutions such as a nurses’ training school, a visiting nurse program, and two hospitals. While historians may be tempted to dismiss flower missions like the one in Indianapolis as naïve or sentimental groups, closer inspection reveals they were much more. My main argument is that though the work of the Indianapolis Flower Mission may at first glance appear trite, it was actually practical and life-saving and deserves serious consideration from historians. First, delivering flowers to the sick and poor had value, especially when we understand how people at the time thought about flowers and what emphasis people placed on spiritual as well as physical health. Second, the Indianapolis Flower Mission quickly transitioned away from simply delivering flowers into work like providing healthcare to the poor. Third, the Indianapolis Flower Mission provided women a respectable way to work outside their homes and gain experience in philanthropic, business, and political activity. Finally, the Indianapolis Flower Mission provides a specific case study that sheds light on other flower missions around the nation and the world.

Biodiversity is being lost around the world and anthropogenic activities, like non-native species introductions and urbanization, are among the leading causes of decline. Broadening our understanding of human-driven impacts on biodiversity can lead to more effective solutions and contribute towards stemming biodiversity losses. In this thesis, I explored the impacts of non-native species introductions and urbanization on butterfly-plant communities. I evaluated potential factors influencing the range expansion of a newly introduced species (Chapter 1), examined the role of urbanization in structuring biological communities (Chapter 2), and identified important ecological interactions between native and non-native species (Chapter 3). In my first chapter, I found that the newly introduced European Common Blue butterfly (Polyommatus icarus) was more abundant in urban and disturbed habitat that was unmown and where their preferred larval host plant (Lotus corniculatus), a non-native species, was present. I also found that P. icarus was not a strong flier relative to other butterfly species, suggesting that adult dispersal may not be a driving factor in range expansion. Instead, this species could expand its range in the future by colonizing habitats in developed regions across Canada given the association I found between P. icarus and disturbed habitat. In my second chapter, I found that urbanization led to the biotic homogenization of butterfly communities around Montréal, QC, favouring a few, highly abundant, non-native species. Homogenization was detected at both the taxonomic and functional levels and was driven by increases in P. icarus abundance in the more urban sites. In my third chapter, I found that non-native plants were well integrated into native butterfly nectar diets in an at-risk oak savanna ecosystem on Vancouver Island, BC and that usage of non-native plants increased when they were more available during the season. I also found that native butterflies visited non-native plants more often than flower availability predicted on its own, suggesting that butterflies may even prefer non-native nectar. Findings from my thesis research broaden our understanding of the ways in which butterfly communities can be influenced by human activities like urbanization and the introduction of non-native species, informing conservation efforts and directing future research needs.
