To evaluate the effects of stock plant nutrition and propagation medium moisture content on stem cutting propagation, two separate studies were conducted. In one study, stem cuttings of Juniperus horizontalis Moench ‘Wiltonii’, Rhododendron (Lindl.) Planch ‘Hino-Crimson’, and Ilex crenata ‘Helleri’, were propagated in 1 peat : 1 perlite (v/v) at 125 %, 250 %, 375 %, 500 %, and 625 % moisture. Stem cutting survival and rooting, midday xylem water potential, and basal water uptake all generally increased with increasing medium moisture level. Incidence of cutting basal rot was not directly related to medium moisture level, but was related to species and growth stage of the stock plant. Basal water uptake by cuttings was highest during the first few days after insertion and thereafter decreased until root emergence. Propagation was most successful in the wettest medium (625 %). In a second study, containerized stock plants of Ilex crenata Thunb. ‘Rotundifolia’ were liquid-fertilized with 25, 50, 100, 200, and 300 mg N · liter⁻¹ in two forms (100 % NH₄NO₃ or 50 % Urea + 50 % NH₄NO₃) in a factorial treatment design. Percent rooting of stem cuttings decreased linearly with fertilizer rate. Leaf and stem percent N increased from suboptimal to excessive levels with fertilizer rate. Total nonstructural carbohydrates (TNC) levels increased in leaves and remained constant in stems with increasing fertilizer rate. Stem cutting percent moisture was highly correlated with fertilizer rate. The form of N applied made no statistical difference in these trends. The decrease in percent rooting with increasing fertilizer rate was attributed to increases in shoot growth activity. / Master of Science

A citricultura brasileira é considerada a mais competitiva do mundo, principalmente devido às excelentes condições encontradas pelos produtores aqui instalados, com ênfase ao Estado de São Paulo, maior produtor mundial de suco de laranja concentrado. Contudo, as características deste ramo do agronegócio favorecem a existência e propagação de inúmeras pragas e doenças. Recentemente a produção cítrica, em especial a produção de mudas, sofreu grandes mudanças. A CVC (Clorose Variegada dos Citros) doença causada pela bactéria Xylella fastidiosa, provocou a obrigatoriedade da produção de mudas cítricas em ambiente protegido desde janeiro de 2003. A produção de mudas cítricas no Brasil sempre se constituiu em atividade de suma importância para o desenvolvimento desta cultura. Porém, da mesma forma que muda de boa qualidade se constitui em um dos principais alicerces da citricultura, uma ruim pode fadar o citricultor à inviabilidade do negócio. Neste contexto o presente trabalho objetivou estudar as características biológicas das duas principais espécies de plantas daninhas que ocorrem em sistemas de produção de mudas cítricas (Oxalis corniculata L. e Cardamine bonariensis Pers.) quanto as condições ideais para sua germinação, verificar sua ocorrência em substratos e suas matérias primas, verificar a eficiência da compostagem da casca de Pinus em seu controle, avaliar o efeito de herbicidas aplicados em pré emergência sobre o substrato no cultivo de mudas e se a presença de O. corniculata afeta o desenvolvimento de mudas cítricas. Os resultados mostram que para O. corniculata as temperaturas que proporcionaram os maiores porcentuais de germinação (G%) foram 20 e 15 °C constantes, sendo nesta espécie o índice de velocidade de germinação (IVG) superior quando as sementes foram submetidas à temperatura constante de 20 °C, ambos os casos quando houve a presença de luz. Para C. bonariensis as temperaturas que proporcionaram os maiores G% foram 20/30 e 20/35 °C alternadas, sendo que para esta espécie o IVG foi superior quando as sementes foram submetidas à temperatura alternada de 20/30 °C, ambos os casos quando houve a presença de luz. As amostras coletadas dos materiais constituintes dos substratos não apresentaram contaminação por nenhum propágulo de planta daninha, detectável pela emergência de plântulas. O processo de compostagem da casca de Pinus é capaz de inviabilizar sementes de O. corniculata, C. bonariensis, Portulaca oleracea e Digitaria spp, bem como tubérculos de Cyperus rotundus em período de 30 dias. Em relação a aplicação de herbicidas no substrato é possível concluir que para as condições onde o experimento foi conduzido, a utilização dos herbicidas oxyfluorfen, flumioxazin, ametryn e oxadiazon não afeteram o desenvolvimento dos porta-enxertos de limoeiro 'Cravo', em nenhuma das doses utilizadas, sendo que aos 80 dias após o transplantio dos porta-enxertos, os herbicidas oxifluorfen e oxadiazon apresentam bons índices de controle de O. corniculata. A presença de O. corniculata nos vasos de produção de mudas cítricas afeta o desenvolvimento das mudas, sobretudo no que se refere à altura do porta-enxerto e massa seca do enxerto. A convivência das mudas com esta planta daninha não afeta o diâmetro do caule das mudas, a massa seca do porta-enxerto, a massa seca da raiz, bem como a massa seca total da muda. O período crítico de prevenção da interferência obtido no trabalho se estende dos 52 aos 69 DAT, admitindo-se 2,5 % de perdas aceitáveis. / The Brazilian citrus production is considered the most competitive in the world mainly because of the excellent conditions that the producers have, with emphasis to the State of São Paulo, the world's largest producer of concentrated orange juice. Despite this, the characteristics of this branch of the agribuisiness are favorable to the proliferation of pests and diseases. Recently, the citrus production, especially the nursery production, has suffered significant changes. The CVC, a disease caused by the Xyllella fastidiosa bacteria has forced the young tree production to be conducted in a protected environment since January 1993. The young citrus tree production has always been considered a very important activity for the development of the citrus culture. A good young tree can be considered one of the bases of the citrus production just as well as a bad young tree can be the factor that makes the business non profitable. In this context, the present study has the objective to analyze the biological characteristics of the two main weed species (Oxalis corniculata L. and Cardamine bonariensis Pers.) that occur in the citrus nursery production systems, verifying the ideal conditions in which their germination takes place, their presence in substrates and its primary material, the efficiency of the bark compost in their control, evaluate the application of preemergence herbicides on the substrate used in the nursery production and if the presence of O. orniculata affects the development of the young citrus tree. The results indicate that for O. corniculata the constant temperatures of 15 and 20°C promoted the highest germination indexes and the exposure of seeds to a constant temperature of 20 °C led to the highest levels of GSI. In both cases the seeds where submitted to the presence of light. For C. bonariensis the alternating temperatures 20/30 and 20/35 °C promoted the highest germination indexes and alternating temperature 20/30 °C promoted the highest levels of GSI. In both cases the seeds where submitted to the presence of light. The samples of the primary material of the substrate did not present contamination with weed seeds, detected through weed plant germination. The bark compost process is capable of invalidating the sedds of O. corniculata, C. bonariensis, Portulaca oleraceae and Digitaria spp and Cyprus rotundus tubers in a period of 30 days. In reference to the experiment conducted in this study, the use of the herbicides oxyfluorfen, flumioxazin, ametryn and oxadiazon did not affect de development of the root stock 'limoeiro-cravo? in any of the doses, and after 80 days of the transplant of the root stock the herbicide oxyfluorfen and oxadiazon presents good control indexes for O.corniculta. The presence of O. corniculata in the citrus nursery containers affected the development of the young trees, especially the height of the rootstock and the dry mass of the graft; it doesn't interfere with the development of the stem diameter and of the dry mass of the rootstock, of the roots our the total dry mass of the young tree. The critical period of competition extends it self from 52 to 69 DAT considering 2,5 % of acceptable lost.

O presente estudo tem como objeto a transição e os percursos das creches diretas da Secretaria de Assistência Social (SAS), para a Secretaria Municipal de Educação (SME), na Prefeitura Municipal de São Paulo durante a gestão Marta Suplicy (PT), de 2001 a 2004. Buscou-se compreender o processo político-administrativo levado a efeito nesse período. Intencionamos ao mesmo tempo, contribuir para o debate sobre creches, buscando apontar alguns indicadores do processo e como o município de São Paulo incorporou o preceito constitucional das creches na área da Educação. Buscou-se utilizar como referências conceituais diferentes teorias da área de política de educação infantil e das políticas sociais dirigidas à infância, objetivando relacioná-las com as políticas de creche no município de São Paulo, evidenciando o contexto histórico-político em que estava inserido. A conclusão do estudo revela que a mudança de área trouxe várias modificações com relação ao atendimento das crianças nas creches, em especial, a organização da demanda, a gestão de sistema e de unidades e a formação de professores. A pesquisadora reuniu e analisou grande parte da documentação que caracterizou a transição e com base nas entrevistas realizadas demonstrou que, embora com contradições, houve avanços para as creches diretas do município de São Paulo. Destaca ainda, que há muito a investir na qualidade do atendimento educacional da criança de 0 a 6 anos no município. / This study aims to track the transition and the course of administration of day-nurseries of the Secretary of Social Assistance (SAS) to Municipal Secretary of Education (SME) of São Paulo City during the administration of the Major Marta Suplicy (PT), from 2001 to 2004. The Administration has tried to understand the political and administrative process carried out during the remaining period. At the same time our intention was that this study could contribute to the debate about day-nurseries, pointing and analyzing indicators that reflected on the developed work and how the schools accepted the constitucional precept of day-nurseries in the area of Education. On the development of this study, we have used as references, different conceptual theories linked to childhood education policies in accordance with social policies targeting to connect them with the policies used in daynurseries in the city of São Paulo, emphasizing the historical and political context in which was inserted. The conclusion reached by this study suggests that is the changing of the area that has brought a lot of modifications about the care of children in day-nurseries as the way of the attendance, the administration of educational system and unit until the organization and formation of staff in this sector. The researcher attended and analyzed great part of the documentation that characterized the transition and added to the interviews showed, although with contradiction in process, that progress was occurring through the day-nurseries for the city of Sao Paulo. Highlights have shown that educational area needs investment and efforts in order to enhance the quality of the attendance for children from 0 to 6 years in the childhood education in São Paulo.

This dissertation responds to Joan Thirsk's call for historians to undertake a closer investigation of commercial gardening. It adopts a micro-historical approach, to address two questions, 'What was a gardener?', and 'What was a garden business?'' Based in the parish of Fulham (including the hamlet of Hammersmith), Middlesex, the parish with the largest acreage of commercial gardening in England in 1796, the study applies nominal linkage to a variety of sources to understand more fully the gardeners, garden businesses, and gardening families between 1680 and 1861. The dissertation exploits sources with occupational descriptors, including livery company apprentice registers, bankruptcies and insolvencies, clandestine marriage registers, Bank of England accounts, and fire insurance policies, not used previously for a statistical examination of gardening. Quantitative data are set in a rich context using qualitative sources such as newspapers, Old Bailey proceedings and property surveys. Tracing occupational terms through the sources shows that records created by parish and government bodies relied on a few customary terms, each encompassing several different functions in gardening, for much longer than commercial documents, demonstrating how reliance on one source can be misleading. In this study I argue that occupational descriptors in gardening reflected the focus, but failed to capture the entirety, of what was produced in a garden business. From the early eighteenth century garden businesses should not be viewed simply as a market garden or nursery; they cultivated a diversity of horticultural products, but are also found to have had a variety of other agricultural interests and economic pursuits, introducing new products and responding to new opportunities: gardeners did not only garden. Contrary to the claims of some historians this was not just an early phase in the transition from agriculture to specialist gardening but persisted into the nineteenth century. This study contributes not only to the history of commercial gardening but also to wider debates in agricultural and business history. From four land-use maps, dated between 1747 and 1843/5 the changing acreage and locations of gardens have been identified, and the first graphical representation of the land use in the parish from the tithe apportionment schedules is presented. The complex interaction between competing land uses is examined providing new findings about how the garden industry adapted in the face of pressures from urban development and other agricultural needs. Examination of the occupational structure of the industry has been approached through several sources. Very few gardeners were apprenticed, but some families continued to obtain training as gardeners and commercial advantages through one of five different livery companies, as well as the Gardeners' Company. The parish registers give the first tentative estimate of the size of the industry, while registers of clandestine marriages suggest that gardeners were a significant proportion of the middling sort in Fulham in the early eighteenth century. Comparison of gardening occupations in the 1841, 1851 and 1861 census enumerators' books provide insights into the structure of the industry but also reveal the inconsistent application of terminology, resulting in the reliability and validity of some of the data being questioned. The implication is that only the 1851 census gives an accurate occupational structure for gardening industry. The findings of previous studies that most gardeners rented their land have been confirmed. On the bishop of London's estate the rents were low during the eighteenth century, but few gardeners were his head lessees and therefore able to benefit. Gardeners had a range of wealth, sufficient for some to have a comfortable living as part of the middling sort while a few had accrued greater wealth from gardening. Garden businesses rarely became bankrupt or insolvent and mainly when there were general economic downturns. Businesses were left predominantly to widows or sons, with the intention of keeping businesses operating and resulting in the establishment of garden business dynasties. The wealth of some businesses demonstrates the benefit of trans-generational transfer, others fared well enough for their business to continue on a smaller scale, but many names came and went from Fulham and Hammersmith commercial gardens in one generation.

This dissertation examines the inherent meanings in the claim that the pre-school is "a complement to the home". The meanings are analysed in order to explore the reasons behind the extension of child care in Sweden, and particularly during the period 1990-1995.The dissertation has two objectives. The first objective is to analyse the aims, as identified by the state and the municipalities, for pre-schools and family day nurseries to act as a complement to the home; with an additional analysis of the children's social and cultural contexts. The second objective is to analyse how employees and parents interpret the idea that pre-schooling is a complement to the home. Date used for this research is national programme information, guidelines used at municipal levels, and empirical data from one questionnaire to staff and two questionnaires to parents. Theories about frame factors and curricula constitute the points of departure for the analyses of the national programmes at state and at local levels, and for the analyses of the questionnaires. The analyses shows that the concept of "a complement to the home" has varied over time and that it is contextually dependent. In the 1930s, when there was a need to improve children's playing environment to compensate for small, cramped, and dark homes, the pre-school was designed to provide large, light rooms. During the 1940s and the 1950s, it was assumed that child care should act as a complement to the home (i.e., not be regarded as a competitor). Such different connotations inherent in the concept of "a complement to the home" reflect the Zeitgeist of the various decades. They also show how the needs of children and family have been expressed; which, in turn, related to the need for women to be active in the labour force. The results of the analyses show that official documents, parents and staff express a belief in pre-schools and family day nurseries as important complements to the homes, particularly in reference to children's social development. But the differences the parents express concerning their children's upbringing are shown to relate to their educational background. The actual activities of the pre-school complement are worked out in close co­operation between parents and staff. Difficulties occur when individual children's needs are taken as a point of departure. This result suggests that the pre-school can be a complement to each child only when divergences in opinions between staff and parents are limited. Family nurseries, which generally are less organised and have fewer children than pre-schools, can provide child care that is more designed to fit the specific needs of children and parents. One of the conclusions of this study is that pre-schools are run on the basis of staff efforts, and that co-operation with parents constitutes a decisive factor in the future development of pre-schooling. / digitalisering@umu

Ögoninfektion är vanligt förekommande hos barn särskilt i kombination med övre luftvägsinfektion. 95% av alla barn mellan två och fem år vistas på förskola. Distriktssköterska/Avancerad primärvårdssjuksköterska ser förskolan som en viktig resurs i det förebyggande hälsoarbetet.
