Following concerns expressed by canegrowers in the Burdekin River Irrigation Area (BRIA) of Northern Queensland regarding rising groundwater and salinity the Department of Primary Industries instigated action to investigate and develop Best-On-Farm Water Management Practices. The purposes of this project were to improve landholder awareness of water use to maximise cane production while minimising the likelihood of salinity and changes in the groundwater balance, and to facilitate the development of soil and water management practices on a range of soils in the BRIA. The project lasted for 12 months, and this short duration affected research methodologies and techniques selected. Groups of farmers were organised, participation was good and useful outcomes resulted. These included: improved landholder awareness of the relationships between salinity, water use and groundwater; identification of a range of best practices; identification of social theories about water management practices; development of an extension model based on the value of indigenous knowledge; equality between government and farmers; examination of underlying assumptions in relation to water management by both government and farmers; identification of issues for future research and extension.<br>Master of Science (Hons)

Previous issue date: 2014-07-28<br>Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>The sweet sorghum can become an important alternative for ethanol production in the sugar cane offseason. For this, adjustments will be necessary in the arrangement of sorghum plants in the field, to use all the available infrastructure and logistics in ethanol plants that use sugar cane as raw material. Besides adjusting the spacing of sweet sorghum cultivation machinery harvesters sugar cane, another factor to be researched refers to weed management. Sorghum is characterized by its slow initial growth which makes it very susceptible to weed competition in the early stage of growth. This fact is compounded by low efficiency of herbicides registered for weed control grasses. In the search for solutions to these problems, this research evaluated the effects of plant arrangements associated with application of herbicides on weed dynamics, sweet sorghum growth and yield. The experiment was conducted under field conditions and evaluated three plant arrangements with spacings of 0.25 m, 0.45 m 0,45 - 0,45 - 0,90 m, keeping the population of 120,000 plants per hectare in all spacings, which were either not associated with herbicide application. At 7, 14 and 28 days after herbicide application visual intoxication plants, weed control and data collection for phytosociological studies of weed community were evaluated. The fresh weight, plant height, stem diameter, mass of broth and °Brix of the sorghum stock were evaluated at harvest, 120 days after sowing. It also assessed chemical characteristics of the broth as the concentrations of sucrose, glucose and fructose, by high performance liquid chromatography efficiency. For phytosociological studies, weed populations were analyzed by calculations of density, frequency and abundance relative importance value (IVI) and similarity index (SI). We conclude that the reduction in sweet sorghum spacing increases the fresh culture weight and the application of the herbicide mixture may be an option in the management of weeds in sorghum, mainly aimed at controlling grasses. However, doses above 960 g ha-1 s-metolachlor and atrazine mixture may compromise the growth and productivity of sweet sorghum. The Cyperus esculentus and Oxalis latifolia species shown to be more tolerant to herbicides, considering that showed higher IVI values, independent of treatment assessed.<br>O sorgo sacarino pode se tornar importante alternativa para produção de etanol na entressafra da cana-de-açúcar. Para isso, serão necessários ajustes no arranjo das plantas de sorgo no campo, para utilização de toda a infraestrutura e logística disponíveis nas usinas de etanol que utilizam a cana-de-açúcar como matéria prima. Além do ajuste do espaçamento de cultivo do sorgo sacarino às máquinas colhedoras de cana-de-açúçar, outro fator a ser pesquisado refere-se ao manejo de plantas daninhas. O sorgo se caracteriza por possuir crescimento inicial lento o que o torna muito susceptível à interferência das plantas daninhas na fase inicial de crescimento. Este fato é agravado devido à baixa eficiência dos herbicidas registrados para controle de plantas daninhas gramíneas. Na busca de soluções para esses problemas, nessa pesquisa foram avaliados os efeitos de arranjos de plantas associado a aplicação de herbicidas sobre a dinâmica das plantas daninhas, crescimento e produtividade do sorgo sacarino. O experimento foi realizado em condições de campo, sendo avaliados três arranjos de plantas com espaçamentos de 0,25 m, 0,45 m e 0,45-0,45-0,90 m, mantendo-se a população de 120.000 plantas por hectare em todos os espaçamentos, os quais foram ou não associados a aplicação de herbicidas. Aos 7, 14 e 28 dias após a aplicação dos herbicidas foram avaliadas a intoxicação visual das plantas, o controle das plantas daninhas e coleta de dados para os estudos fitossociológicos da comunidade infestante. A matéria fresca, altura de plantas, diâmetro de colmo, massa de caldo e °Brix do caldo do sorgo foram avaliados no momento da colheita, 120 dias após semeio. Também avaliou-se as características química do caldo quanto as concentrações de sacarose, glicose e frutose, por cromatografia líquida de alta eficiência. Para os estudos fitossociológicos, as populações de plantas daninhas foram analisadas por meio de cálculos de densidade, frequência e abundância relativa, índice de valor de importância (IVI) e índice de similaridade (IS). Conclui-se que, a redução no espaçamento entre linhas do sorgo sacarino aumenta a massa fresca da cultura e a aplicação da mistura de herbicidas pode ser opção no manejo de plantas daninhas no sorgo sacarino, principalmente, objetivando o controle de gramíneas. No entanto, doses acima de 960 g ha-1 de s-metolachlor em mistura com atrazine podem comprometer o crescimento e produtividade do sorgo sacarino. As espécies Cyperus esculentus e Oxalis latifolia demonstram ser mais tolerantes aos herbicidas aplicados, tendo em vista que apresentaram maiores valores IVI, independente do tratamento avaliado.

Full textAbstract:
This project “Growing with Care” deals with the complex issues of food security, climate change, and building communities. Food is one of the most important aspects of life, it sustains us, it can bring us together and tears us apart. This project is addressing the problem of the industrialisation of the agriculture system and the impact it’s had on our environment and society. It’s resulted in a society that’s almost completely disconnected from the food being eaten. Metadesign will be used throughout the process of this project. Metadesign methods will be used to provide guidance, tools and support for participants to create their own change in the way they interact with their local food systems. It will be used to help participants form food communities in different cities. The solution suggested in this project, is to rebuild care relationships to soil and the natural elements in our food systems. For participants to grow more food in their local areas with embedded care methods and a conscious understanding that we are living in an interconnected world. The outcome in this project is a toolkit in the form of a blog and booklet. It uses metadesign methods to provide participants with tools to deal with the problems that arose from the industrialisation of agriculture. It encourages the participants to create local change as a community, for a more secure food future.

Full textAbstract:
Interprofessional education (IPE) is, in some cases, a genuine effort to improve health professions training programs and in others, a "box that must be checked" for program accreditation. The types of training and trainees involved in IPE initiatives are wide-ranging, and efforts to articulate measurable competencies for different developmental levels and disciplines are in their infancy. Still, leaders in IPE have indicated that just as the evolving healthcare system is putting new training demands on academic health centers/health professionals training programs to teach team care, strong IPE programs can fuel and empower the health care industry. In this session, a panel of IPE leaders from a range of professional backgrounds (nursing, pharmacy, medicine, psychology) answer essential questions about the evolution and trajectory of IPE as a catalyst for improved health care. Describe the current tensions in the academic environment around IPE programming. Identify crucial "next steps" for IPE programs in better fitting with health care evolution. Discuss how IPE could, if empowered to do so, fuel an even stronger team care capacity within health care.

Stengel, Emily. "Supporting A Growing Agricultural Economy By Understanding Child Care In Farm Families." ScholarWorks @ UVM, 2015. http://scholarworks.uvm.edu/graddis/418.
Full textAbstract:
This thesis argues for the consideration of child care accessibility and costs as one factor in the success and wellbeing of farmers in the United States. There is a long tradition in rural studies of recognizing that farms are not just economic enterprises but are family-based social enterprises as well, with household level issues and family roles that are both acknowledged and contested. However, child care is missing from virtually all scholarly and public discussions of agricultural workforce development - even more so than other social services and family supports. Additionally, the agricultural sector, considered as a portion of U.S. businesses and as a locus of U.S. family life, is missing from most discussions of child care services. Although child care has been shown to be crucial to workforce development, and the need for workforce development in the agricultural sector is vital in light of an aging farm population, the agricultural sector has remained largely absent from child care policy discussions. This two-article thesis seeks to inform scholarship and public policy in both of these areas.
Using data from a national survey of 186 farm families at the Rural-Urban Interface, Article One examines child care challenges faced by farm families and the influence community networks have on these challenges. This article focuses specifically on two groupings of farmers: multi-generation (MG) and first generation (FG) farmers, as part of a larger effort to support beginning farmers; and men and women farmers, as challenges related to child care are of particular concern for the increasing numbers of women farmers, who may have multiple roles including primary child caregiver, wage-earner through off-farm employment, and farmer. Findings establish that child care is an issue that influences farm business decisions for farmers, that FG and women farmers are farming populations that are more likely to have challenges with child care, and that family networks are an influencing factor in child care problems for MG and FG farmers.
Through analysis of interviews and focus groups with 43 farmers in the Northeastern United States, a geographic region chosen for its high concentration of female farmers, Article Two seeks to understand child care in farm families by examining patterns in farmers' experiences with child care and the ways child care affects both the farm family and the farm business. Findings reveal child care as an issue in the wellbeing of both farm family and farm business: child care has economic effects on the farm business, influencing decisions about labor, growth, and financial resources; child care also has social effects on the farm family, including shifts in gender roles, stress, and reduced quality of life.
Recommendations include child care subsidies specifically for farm families and the creation of formal child care networks that could allow for collaboration and use of already-existing networks of agricultural organizations: Extension, food policy councils, and producer groups. Additionally, state level departments of family and youth services, local child care organizations, and community development corporations are urged to tailor their resources specifically to farm families.

Full textAbstract:
Includes bibliographical references (leaves 84-102).<br>HIV positive adolescents are becoming a progressively more sizeable and prominent sub-group in the South African HIV/AIDS epidemic. As HAART becomes increasingly available, vertically infected children can be expected to survive into adolescence and adulthood. Additionally, sexual transmission of HIV remains a problem, and incidence and prevalence rates among South African youth are high. Experience from the developed world indicates that providing effective care and treatment for youth can be a challenging task. In light of the antiretroviral rollout in South Africa, this exploratory study aimed to identify the experiences and needs of adolescents growing up in care or on treatment for HIV in the Western Cape. To this end, a review of the existing literature on the psychosocial aspects of HIV infection in adolescents was undertaken. Relevant articles were identified, summarized and entered into a database, and particular attention was given to research conducted in the context of sub-Saharan Africa. Additionally, focus groups interviews were conducted with 26 young people attending an adolescent infectious diseases clinic at a tertiary hospital in the Western Cape. Focus groups proceeded according to a pre-set discussion guide and investigated participants' current life experinces, views on the future and self-perceived needs. All interviews were recorded, translated into English, and transcribed, and data were coded and analyzed using NVivo qualitative data analysis software. The study revealed that the psychosocial issues associated with HIV infection in adolescents coalesce around five central themes: knowledge and understanding about personal serostatus, mental health, network of support, treatment management, and healthy behaviour. These issues present challenges to HIV positive adolescents in the present, and affect their outlook on the future. Findings reveal that despite the fact that young seropositive South Africans live in a country where social contexts, available resources and healthcare systems differ markedly from those in developed countries, they share similar concerns and face many of the same challenges as other HIV positive young people around the world. Future studies should investigate each of the five identified themes in greater depth by determining the contextual correlates of individual views, experiences and needs.

Full textAbstract:
This study is an investigation of long-term foster care, which focuses on the reflections of 40 adults, aged 18-30, who grew up in foster families. The theoretical approach taken is developmental and the study draws on theories of attachment and resilience. The research method was qualitative. In-depth interviews were conducted, transcribed and analysed in order to generate a picture of the pathways taken through childhood and into adult life. The primary focus of the interviews was on family relationships and the development of the self, but relationships with peers, school experiences and practice relevant issues, such as what it meant to be `in care', the experience of stigma and the role of social workers, were also discussed. The analysis used the dimensions of placement continuity, the quality of family relationships and the nature of family membership to identify seven different pathways. The data suggests that although the development of secure emotional relationships is an important part of successful placement experiences, the development of a sense of family membership is also highly significant, particularly in adult life. In a psychosocial model of long-term foster care, a `secure base' can therefore be understood in attachment terms as an emotional resource, but can also be understood in a more social context, as providing a family identity and a place in society. The study concludes that foster families where there are no biological or legal ties can still be a form of permanent family placement. This has important implications for social work practice, both in the way in which placements are planned and in the importance of promoting continuity into adult life of relationships which officially end when a child leaves care. It requires a change in attitudes, so that long-term foster families are no longer treated as placements for childhood only, but are recognised as offering a home and a family for life

Full textAbstract:
Agricultural and educational researchers recognize the critical value of an integrated, multidisciplinary approach to education in building a food-secure world, reducing poverty, and conserving and enhancing natural resources. However, schools generally contribute little to communities in the context of food growing and environmental learning. The main objective of this qualitative research was to explore the role of school-community relationships in enabling environmental learning in the context of food growing activities. Findings suggest that the role of school-community links in enhancing environmental learning is more likely where community members are actively involved in school programs that have an emphasis on an experiential learning approach. However, this depends to a large extent on the availability of parents or concerned community members and their willingness to engage in voluntary school-based activities. Factors that could potentially strengthen the role of school-community links in supporting environmental learning include: allowing space for informal learning, mediating learning in civil society settings, ongoing facilitation by a committed coordinator, community buy-in and accountability, and addressing public interests through tangible benefits. A major challenge is to find an appropriate balance between social justice and practical food security concerns, while remaining true to ecological considerations.

Full textAbstract:
South Africa has wide ranges of plants among which are leafy vegetables growing in the wild. These wild vegetables have been reported to have high nutritive and medicinal potentials. Yet, there is still high prevalence of malnutrition and micronutrients deficiencies among the low income bracket of the population. Effective utilization of wild vegetables has been proposed as part of the solutions to address the problem of dietary deficiencies among the populace. Their importance is mainly as relish to accompany and complement starch based diets. They are also known to serve as supplements for food which have the potential to improve the health status of its consumers in many rural communities. Cleome gynandra L. (Capparaceae) is one of the underutilized species mentioned during asurvey conducted in Nkonkobe municipality of the Eastern Cape Province, South Africa. The plant is an erect annual herb with alternate, palmately compound leaves and its petals are white, pink or lilac. It grows as a weed in this part of the Province and is usually gathered from the wild for food and medicine. It is commonly found on wastes land, road sides and on grass lands. Therefore, this research work was designed to contribute to the possible domestication of this wild vegetable in order to explore the nutritive and therapeutic potentials which would broaden the food base in the Eastern Cape Province. The ultra-micromorphological features of plants have become an essential tool in proper identification and authentication of several plant species. In the light of this, the micromorphology of Cleome gynandra was examined to reveal the micro-morphological characters of the plantand to determine if micro and macro mineral elements are present using energy dispersive x-rays. The present study revealed the epidermal cells of the leaves to be asymmetric in shape with undulating cell walls having four subsidiary cells around the stomata. The leaves have anomocyctic stomata which are more distributed in the abaxial surface than the adaxial surface. The mean length and width of the guard cells in the abaxial surface are 0.09 ± 0.01 mm and 0.08 ± 0.01 mm respectively while that of adaxial surface are 0.1± 0.01 mm and 0.07 ± 0.01 mm respectively. The energy dispersive x-rays (EDXS) micro-analysis of the leaf revealed the presence of phosphorus, manganese, iron, calcium, sodium, magnesium, potassium and zinc as the major constituents of the crystal deposits present in the stomata pores and the mesophyll. C. gynandra was collected from the wild and analysed for its mineral and proximatecomposition using standard analytical methods. The plant showed high levels of sodium, iron, zinc, calcium and potassium while many other macro and micro minerals were moderately present. Amongst the proximate factors investigated, moisture content was found to be 82.1% while crude fibre and protein contents were 39.9 percent and 31.03 percent respectively. Vitamin C was also high (345.3 mg/100g). The anti-nutrients compositions revealed low concentrations of oxalate (7.4 ± 0.4) and phytate (0.6 ± 0.0) mg/100g. The study revealed high nutritive value of the species growing naturally from the wild. Interest in the phenolic compounds has greatly increased recently because these compounds have been implicated in suppressing the risk of degenerative diseases in humans. The pharmacological properties of plants may be related to their antioxidant capacities and hence there was need to investigate the antioxidant potential using aqueous, ethanolic and acetone extracts of different parts of C. gynandra. The quantities of phenols, flavonoids and flavonols were significantly higher (p < 0.05) in both aqueous and ethanol extracts of the leaf while the concentration of proanthocyanidins was higher in the aqueous stem extract compared to other plant parts. The aqueous extract of the different parts exhibited better ABTS, reducing power and NO radical scavenging abilities than ethanol extract.

Full textAbstract:
[Truncated abstract] The commercial developments of the late 20th and early 21st centuries have come to signify profound and far-reaching change in the way that goods and services are designed, produced, marketed and delivered to customers in the world's international and domestic markets. In order to respond to a more intensively competitive trading environment that demands ever-increasing levels of product quality, customer service, organisational efficiency and business performance, the management of business entities has undergone fundamental alteration in form and content. It is within this context that two traditionally disparate business disciplines have emerged to play an important role in the new economic commercial order, that of small business management and that of Strategic Human Resource Management (SHRM). Historically eclipsed by the large and powerful mass-producing corporations, the small business sector has been more recently viewed as playing an increasingly prominent part in the creation of national and regional prosperity within the developed countries. The unprecedented interest in smaller firms and the desire to see them fulfill their economic and social potential have resulted in legislative reform and widespread initiatives by governments and other institutions designed to support and protect the smaller operators in their commercial endeavours. Similarly, in the post-industrial knowledge economy people have risen in prominence over other organisational resources as a key source of competitive commercial advantage. The role of intellectual capital in securing business success has fuelled the development of management technology and methods designed to enhance the contribution of human resources to business performance. Heralded by many as the defining managerial approach for enterprises that wish to build sustainable competitive advantage in the markets of today and the future, SHRM has come to the fore as a means to re-evaluate the importance of human contribution to business outcomes and guide management practice in leveraging the latent potential of a company's human assets. ... In general, the management of business strategy was found to possess low levels of structure and formality, effectively merging into the collective activities associated with owning and operating a small business. Similarly, when compared with the key elements of a strategic human resource management framework constructed specifically for this study, the data indicated that the strategic management of people is prevalent in smaller firms but that this again represents only partial adoption of normative models as commonly promoted for the larger business management context. It was concluded that the theoretical principles and concepts of SHRM demonstrate relevance for small companies on account of the status of the contemporary external commercial environment in which they must compete as well as the range of managerial benefits associated with strategic methodology and practice. However, currently there exist no suitable models of practice with supporting guidelines that respond to the unique contextual and operational needs and experiences typical of smaller firm owner-managers.

Full textAbstract:
Background and purpose: For many young adults with cleft lip and palate (CLP), traditional team services come to an abrupt end at age 18, necessitating a transition from child-centered to adult-centered care. There is a shift in focus from the cleft itself and clinician reported outcomes to patient self-report about the perceived impact of the cleft. Transition also befalls the parents and team providers. We propose an evidence-based person-centered delivery model of care using the concepts of the International Classification of Functioning, Disability, and Health (ICF) (WHO, 2001, 2004). The ICF represents a shift from health condition and body impairment-centered descriptions of disability to a more comprehensive documentation, including a wider range of functionality indicators. This model of Transition of Care is proposed to facilitate a positive shift from pediatric to adult-centered care. It is timely for teams to embrace the concept of transition of care, and to provide services that recognize the importance of personal and environmental factors in facilitating holistic transition planning and service delivery (ICF, WHO, 2001), which are developmentally appropriate to young adults with CLP (Farre & McDonagh, 2017; Farre et al., 2016).The purpose of this proposed evidence based model is to provide a framework for redesigning the way services are delivered to a young adult with CLP. The concepts of this model are relevant to all specialists on the cleft palate team. The aim of this presentation is to create an awareness of young adults with CL/P who are generally a neglected population in terms of team care and to suggest a new and fresh approach to service delivery to these individuals with the emphasis on clinical resources.Content: A brief overview of adolescents and young adults with CLP and their multidisciplinary needs will be presented. A framework for a holistic service delivery model developed by Vallino and Louw (2017) will be presented. We will suggest strategies for teams to improve the care for young adults with CLP and share a clinical toolbox comprised of a compendium of resources.Conclusion: The proposed Service Delivery Model for young adults with CLP necessitates a change in perspective that embraces constructs such as person-centered care in order to ensure the best outcomes for these individuals. These concepts can be applied by all cleft palate team members. Adopting a life span perspective reinforces the understanding that living with and managing CLP is dynamic and that transition is a process rather than a point in a person's life.

Full textAbstract:
This dissertation is based on research conducted at a small state-managed conservancy called the Edith Stephens Nature Reserve (ESNR) situated in the low-lying flatlands of the Cape Town metropolis. By tracing some of the complex and varied ways in which different ways of knowing and valuing urban "natures" and practices of conservation co-constitute each other, this dissertation critically engages with the social power relations at work in the continual making and unmaking of Cape Town's "natural" heritages. In doing so, I argue for recognizing the ways in which Cape Town's urban "natures" remain entangled with the epistemological, ecological and spatial legacies of colonialism and apartheid. Moreover, by focusing on the ESNR, I explore the current material and discursive practices by the state in relation to urban "nature" conservation. In recent years, the discursive framework of biodiversity conservation was mapped onto ESNR through the state apparatus. At the same time, ESNR was identified as pilot site for an experimental partnership project that was called Cape Flats Nature (CFN), a project that ran from 2002 till 2010 which explored what biodiversity conservation would mean within marginalized, poverty-stricken and highly unequal urban landscapes. By engaging with ESNR's historically constituted material- discursivity, this dissertation argues that, during this time, a particular relational knowledge emerged which, in turn, co-crafted and configured the emerging poetics, politics and practices at ESNR. In doing so, I foreground my main argument - that urban "nature"conservation, far from only being about conserving and caring for nonhuman life worlds, is rather simultaneously about conserving a particular relation to the world, to others and to oneself.

Full textAbstract:
This study builds an integrative framework to delineate the process of growing entrepreneurial firms in developing countries. Deriving from the existing entrepreneurship literature, this thesis uses two notions to delineate the process of growth of indigenous firms: entrepreneurial intent and entrepreneurial capability. Then, drawing on the literature of economic development, it identifies three key sectors, the state, the market and the social sector, that foster entrepreneurial intent and cultivate entrepreneurial capability.<br>The research setting is the information technology (IT) industries in China and Taiwan, each of which has had impressive performance when compared with their counterparts in other developing countries. This study differentiates the growth of entrepreneurial firms into three stages, getting started, getting there, and staying there, and proceeds to analyze the comparative-historical experiences of six IT firms, three in China and three in Taiwan. The firms in China are the Advanced Technology Service Division (ATSD), Lenovo Computer, and Great Wall Computer. The firms in Taiwan are United Microelectronics Corporation (UMC), Acer, and Vanguard International Semiconductor (VIS).<br>It is found that at the stage of getting started, the government tends to be key among the three sectors, and can broadly influence the firms' entrepreneurial intent by building the national institution context, and more specifically through industrial policies. At the stage of getting there, the domestic social sector becomes more salient, and can transfer technology to entrepreneurial firms either from abroad or from their own research; they can also help defend entrepreneurial firms in intellectual property disputes with multinational firms. At the stage of staying there, due to their advanced technology, multinationals as forces in the market become more prevalent, and can enhance or destroy the capability of entrepreneurial firms. Overall, the state can act as context builder, champion and confronter; the social sector can play the roles of capability builder and capability defender, while the market, via multinational firms, can play the roles of capability destroyer and capability enhancer.

Previous issue date: 2013<br>Resumo: No atual período histórico, a importância crescente dos fluxos de todas as ordens (mercadorias, pessoas, serviços, dados, informações, capital) remete à necessidade de racionalização, otimização e operacionalização da circulação e comunicação de acordo com a ótica dos agentes econômicos hegemônicos, configurando um uso corporativo e seletivo do território. Novos sistemas técnicos agrícolas se difundiram ancorados em densas cargas científicas, tecnológicas e informacionais, permitindo a reestruturação produtiva do setor, isto é, a promoção de transformações nos elementos técnicos e sociais da agricultura. A racionalização dos intensos fluxos de mercadorias e informações fez com que a logística assumisse uma importante função na produção agrícola, cada vez mais especializada e fragmentada espacialmente. Considerando a logística como elemento espacial do atual período, propomos identificar e analisar as competências logísticas materiais, normativas e operacionais que conferem fluidez territorial e competitividade aos agentes do circuito espacial produtivo do café na região do Sul de Minas. Especificamente, buscaremos apresentar as características que nos permitem considerar esta porção do território brasileiro uma região competitiva agrícola, atrelada à produção do café. Também procuraremos analisar o circuito espacial produtivo dos 'cafés especiais', com ênfase na organização logística dos fluxos materiais e imateriais. Para tanto, usaremos como estudo de caso, a organização logística da empresa exportadora de 'cafés especiais', Bourbon Specialty Coffees, com sede na cidade de Poços de Caldas/MG e atuação nas principais regiões cafeeiras do país, com destaque para o Sul de Minas<br>Abstract: In the current historical period, the importance of the increasing orders of all things (e.g.: goods, people, services, data, information, capital) calls for the necessity of communication and circulation of the rational, optimal and operational aspects in accordance to the optics of the hegemonic economical agents, configuring a corporate and selective use of the territory. New agricultural technical systems have widespread anchored to heavy scientific, technological and informational loads, permitting the productive restructuring of the sector, that is, the promotion of transformations in social and technical elements of agriculture. The rationalization of the intense flow of goods and information made logistics assume an important position in the agricultural production, increasingly more specialized and spatially divided. Considering logistics as a spatial element of the current period, we propose to identify and analyze the material logistical ability, normative and operational that confer territorial fluidity and competitiveness to the spatial productive circuit agents of coffee in the south of the Minas Gerais region. Specifically, we will seek presenting the characteristics that allow us to consider this portion of the Brazilian territory a competitive agricultural region, linked to the production of coffee. We will also analyze the spatial productive circuit of the 'special coffees', with emphasis in the logistical organization of the material and immaterial flow. In as much, we will use as a case study, the logistical organization of the 'special coffee' export company, Bourbon Specialty Coffees, situated in the city of Poços de Caldas/MG and its operation in the main coffee regions of the country, mainly in the South of Minas<br>Mestrado<br>Análise Ambiental e Dinâmica Territorial<br>Mestre em Geografia

Full textAbstract:
Abu Dhabi é a capital dos Emirados Árabes Unidos e o maior emirado em termos de área e população. Os emirados árabes unidos tem um elevado índice de morbilidade e mortalidade relacionados com as doenças crónicas. Para abordar o crescente problema das doenças não comunicáveis, o Modelo de Doença Crónica (CCM) tem a intenção de ter cuidados diários baseados na população, com intervenções de equipa estruturadas e planeadas; com o objectivo de converter a vida dos doentes crónicos de reactiva a proactiva. O modelo integra seis elementos para facilitar uma qualidade elevada dos cuidados.
Objectivos
Esta tese tem como objectivo explorar o sistema de saúde de Abu Dhabi usando a abordagem do CCM para melhorar e desenvolver a prestação de cuidados a pessoas com doenças crónicas.
Foram desenhados quatro objectivos específicos:
Caracterizar os serviços de saúde do emirado de Abu Dhabi;
Analisar o alinhamento dos serviços de saúde com o CCM, identificando as principais lacunas;
Explorer a percepcão dos profissionais de saúde sobre o nível de integração do CCM nos cuidados diários a doentes com diabetes, doenças cardiovasculares e cancro;
Priorizar os subcomponentes e as barreiras para o desenvolvimento do CCM no sistema de saúde do emirado de Abu Dhabi.
Métodos
Para operacionalizar os objectivos foi desenhado um estudo com três componentes distintas:
Revisão sistemática da literatura usando o CCM como uma framework para explorar a sua implementação e desenvolvimento nos cuidados de saúde primários; Estudo transversal misto para recolher informações sobre a percepção dos profissionais de saúde sobre os cuidados diários a doentes crónicos;
Painel Delphi utilizado para ordenar as prioridades e barreiras da implementação e desenvolvimento do CCM.
Resultados
As clinicas que prestam cuidados de saúde primários adotaram os princípios do modelo Patient-centered medical home, que está alinhado com o CCM. Parece que existe um esforço em seguir as últimas evidências científicas com a intenção de atingir ganhos em saúde. A implementação dos elementos do CCM está alinhada com os standards e é positivamente associada com o uso de intervenções dirigidas a comportamentos de alto risco. Os profissionais de saúde têm a percepção de que cinco elementos (sistemas de informação clínica, decisão suportada, comunidade, autogestão e sistema de saúde) foram considerados razoavelmente bons. Os participantes deram pontuações elevadas a alguns componentes, no entanto, os resultados qualitativos nem sempre suportaram os resultados quantitativos, indicando ainda a transição do modelo centrado no médico para o modelo centrado no doente. A ‘liderança organizacional para os cuidados da doença crónica’ foi considerada como a primeira prioridade (26.3%) e ‘participação do doente’ foi considerada como a primeira barreira (36.8%).
Conclusão
O sistema de saúde do emirado de Abu Dhabi está internacionalmente bem posicionado e competitivo face a outros países desenvolvidos, mesmo enfrentando o desafio da sua população única. Tem um razoavelmente bom suporte aos cuidados de doença crónica e o top cinco das prioridades e barreiras estão delineados. Este estudo representa um importante passo para compreender onde e mais relevante intervir de forma a maximizar o desenvolvimento do CCM no Sistema de saúde de Abu Dhabi.<br>Abu Dhabi is the capital of the United Arab Emirates (UAE) and the largest emirate in terms of land mass and population. The UAE has a high population-burden of morbidity and mortality related to chronic diseases. To address the growing burden of non-communicable diseases, the Chronic Care Model (CCM) has the purpose of having population-based daily care for all with structured and planned team care interventions; aiming to convert the life of patients with chronic disease from reactive to proactive. The model integrates six elements to facilitate high-quality care.
Aim and Objectives
This thesis aims to explore the health system of the Abu Dhabi emirate, using the CCM approach to improve and develop the healthcare delivery to people with chronic diseases.
Four specific objectives were outlined:
Characterize the healthcare services in the emirate of Abu Dhabi;
Analyze the alignment of the healthcare services with the CCM, identifying main gaps;
Explore the perception of the healthcare workers about the level of integration of the CCM in the daily care of patients with chronic diseases: diabetes, cardiovascular diseases, and cancer;
Prioritize the subcomponents and the barriers for the development of the CCM in the health system of the emirate of Abu Dhabi.
Methods
To operationalize the objectives, a study with three different components was designed:
Systematic review used the CCM as a framework to further explore its implementation or development in primary health care; The cross-sectional mixed-methods study collected information about the perception of the healthcare workers about the stage of implementation and development of the CCM in the daily care of patients;
Modified Delphi technique was used to rank the priorities and barriers of the implementation and development of the CCM.
Results
The primary health care clinics adopted the principles of the patient-centred medical home model, a model aligned with the CCM. It seems there is an effort in following the latest scientific evidence with the intention to achieve health gains. The implementation of the CCM elements aligns with those standards and is positively associated with the use of interventions targeting high-risk behaviours. The healthcare workers have the perception that five elements (i.e. clinical information system, decision support, community, self-management, health system) were rated as reasonably good. Participants awarded high scores for some components; however, the qualitative findings did not always support the quantitative data indicating that the transition from doctor-centred to patient-centred is still in process. The ‘overall organizational leadership in chronic illness care’ was considered as the priority to address (26.3%) and ‘patient compliance’ the top barrier (36.8%).
Conclusion
The Abu Dhabi emirate health system is internationally well positioned and competing with others from the high-income developed countries, even facing the challenge of the unique population. It has reasonably good support for chronic illnesses care and the top five priorities and barriers to further improve it was outlined. This study represents an important step to understanding where it is more relevant to intervene in order to maximize the development of the CCM in the Abu Dhabi health system.

Full textAbstract:
As a child approaches adulthood, many transitions take place; physically and psychosocially. There are new roles and responsibilities. For the young adult with cleft lip and palate (CLP), one of the most significant transitions is moving from the pediatric interdisciplinary team to the adult-centered health care system. There is a shift in focus from the cleft itself and clinician-reported outcomes to patient self-report about the perceived impact of the cleft on quality of life. Transition also befalls the parents and team providers who, through the course of some 18 years, were active participants in the young person's care. Their roles, too, have changed. The International Classification of Functioning, Disability, and Health (ICF; World Health Organization, 2001, 2004) is a conceptual framework for considering the totality of the cleft by addressing the interaction between the person and their personal and social environment. This model is suitably applicable to the transition of care of the young adult with CLP. In this paper, we propose an evidence-based person-centered delivery model of care using the concepts of the ICF to facilitate the transition of care for this population. A case example is presented highlighting the use of these concepts for the speech-language pathologist.

The use of the chemical ripeners, in the sugarcane crop, did not affect some important technological characteristics, for the industry quality samples, such as: phenolic compounds, total acidity, and volatile acidity. The precipitation that occurred during the sampling period (43 daa) benefited the reestablishment ...(Complete abstract, click electroni access below)

Full textAbstract:
The study aims to evaluate the biomass production and nutrient content and silage quality of perennial ryegrass (Lolium perenne (L)), cocksfoot (Dactylis glomerata (L)) and tall fescue (Festuca arundinacea (Schreb)). Six varieties were used, two for each species. A completely randomized block designed replicated three times was conducted at University of Fort Hare Research Farm during 2014-2015 growing season. The plots were harvested at four-week interval (post emergency) for one year. Biomass yields were measured for fresh forage and dry matter yield. Duplicated samples were then dried, milled and analyzed for chemical and mineral composition (CP, NDF, ADF, and ash, Ca, P, K, Na, Mn, Cu, Zn and Fe) for only winter season. In addition the grasses were ensiled and the silage was analyzed for its fermentation parameters and nutrient content (lactic acid, pH, DM, CP, NDF, ADF, and ash, Ca, P, K, Na, Mn, Cu, Zn and Fe). Biomass results showed significant differences (P < 0.05) between season and varieties. On average Tall fescue varieties Jessup (13741.67 FM kg/ha), Alix (12007.78 FM kg/ ha) and Ryegrass varieties Samson (11597.22 FM kg/ha) and Nui (10591.67 FM kg/ha) had the highest fresh biomass yield. Similarly, Tall fescue varieties Jessup (2833.06 DM kg/ha) and Alix (2708.3 DM kg/ ha) and Ryegrass varieties Samson (2169.44 DM kg/ha) and Nui (2169.67 kg/ha) had the highest dry biomass yield. Throughout the year the average biomass yield was significantly different among species (P< 0.05). During summer and autumn Tall fescue varieties Jessup and Alix gave the highest dry matter yields of 3855.5 to 1977.8 DM kg/ha, and 3877.8 to 1900 DM kg/ha, respectively, and followed by Cocksfoot 2400 DM kg/ha. Ryegrass had the highest dry matter biomass yield in winter (2975 DM kg/ha) and the least in summer (977.75 DM kg/ha). There were no significant (P>0.05) differences on the chemical composition (CP, NDF, ADF, and ash) and mineral composition (Ca, P, K, Na, Mn, Cu, Zn and Fe) of the six varieties. The grass silage results showed significant differences (P< 0.05) among the six varieties for moisture content. Perennial ryegrass variety Nui (66.76 percent) had low moisture content than the other grass silages. The different varieties had no significant effects (P>0.05) on chemical composition (CP, NDF, ADF, and ash) and mineral composition (Ca, P, K, Na, Mn, Cu, Zn and Fe). It is concluded that the biomass production of the six varieties of three grass species was different throughout the year under irrigation hence Ryegrass and Tall fescue are recommended for dairy farmers in the region for all seasons. It can be concluded that there is no difference with respect to fermentation characteristics and nutrient content among the varieties of the grass species.

Full textAbstract:
Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>This work was carried out to evaluate the performance and carcass characteristics of grass carp (Ctenopharyngodon idella) juveniles in response to dietary protein levels and sources. For this, two experiments were conducted: the first (80 days), evaluating four crude protein (CP) levels (22, 30, 36 and 44%) and the second (60 days), comparing protein sources in the diet: FCS (porcine meat meal -
control); FC: canola meal; FG: sunflower meal and FCG: canola meal + sunflower meal. Both experiments were conducted in a water re-use system composed of 12 tanks (850 L), with three replicates per treatment. In experiment 1, 10 fish by tank (initial weight 153,0±1,5g) were fed 3% of body weight, twice daily, and the experiment 2 was provided ration (2% of biomass) in the morning and forage (Napier grass ad libitum) in the afternoon, to 15 fish by tank (initial weight 54,6±1,0g).
Growth parameters (weight, specific growth rate, daily weight gain, relative weight gain and feed conversion ratio) and carcass (carcass and fillet yield, digestive somatic index, hepatic somatic index and visceral fat index, intestinal quotient, protein retention, protein efficiency rate and whole body and fillet protein and fat deposition) were evaluated. Moreover, the proximate composition (moisture, ash, fat and protein) in fillet and whole fish and blood parameters (glucose, total triglycerides, total cholesterol and total protein in both experiments and hematocrit in Experiment 1) were also evaluated. In experiment 2 was also determined the daily consumption of forage and the instrumental color. In
experiment 1, linear positive effect of protein level for all growth variables was observed. However, the same effect was observed to whole body and fillet fat deposition, triglycerides and total cholesterol
in serum, indicating that the protein from the diet was used as energy source. To feed conversion ratio
and fat in whole fish, the effect was quadratic, with maximum response with 40.6 and 37.1% CP, respectively. Protein retention, protein efficiency ratio, protein deposition in whole body and fillet and hematocrit also showed linear positive effect, while the other parameters were not affected. In experiment 2, the growth parameters and the daily consumption of forage (1.24 to 2.11% of body
weight) did not differ among the treatments. About proximate composition of whole fish, higher fat content and lower protein content, besides fillet ash, were obtained in the treatment FCG. The diet FCS presented the highest values of serum protein, triglycerides and total cholesterol. The fillet yield was higher in the treatments FCG and FC, while the digestive somatic index was higher in treatment FG and FCG. In the instrumental evaluation of color, the fillets from FCS and FCG diets showed higher value of L (brightness), differing only treatment FC. The other parameters did not differ among them. Based on this results, we can conclude that: the minimum protein level for maximum growth of grass carp in the growing phase, with practical diets, is 44%; the variation in dietary protein level promotes changes in metabolism of juvenile grass carp, reflected in hematological and carcass
parameters; canola meal and sunflower meal can be used in diets for grass carp growing phase, when supplemented with limiting essential amino acids, without compromising growth.<br>Este trabalho foi conduzido com o objetivo de avaliar o desempenho produtivo e qualidade de pescado de juvenis de carpa capim (Ctenopharyngodon idella) em resposta a níveis e fontes de proteína da dieta. Para isso, foram conduzidos dois experimentos: o primeiro, com 80 dias, avaliando quatro níveis de proteína bruta (22, 30, 36 e 44%) e o segundo, com 60 dias, avaliando fontes protéicas na dieta, em combinação com farelo de soja: FCS: farinha de carne suína; FC: farelo de canola; FG: farelo de girassol e FCG: farelo de canola + farelo de girassol. Ambos os experimentos foram conduzidos em sistema de recirculação de água com temperatura controlada, composto de 12 unidades experimentais (850 L), com três repetições por tratamento. No experimento 1, 10 animais por unidade experimental (peso inicial 153,0 ± 18,2g) foram alimentados com ração (3% da biomassa) duas vezes
ao dia. No experimento 2, foram utilizados 15 animais por unidade experimental (peso inicial 54,7 ± 7,8g), alimentados com ração (2% da biomassa) pela manhã e capim elefante (à vontade) à tarde. Foram avaliados os parâmetros de crescimento (peso, taxa de crescimento específico, ganho em peso diário e relativo e conversão alimentar aparente) e de carcaça (rendimento de carcaça e filé, índices digestivossomático, hepatossomático e de gordura visceral, quociente intestinal, coeficiente de retenção protéica e deposições de proteína e gordura corporal e no filé). Além disso, a composição centesimal (umidade, cinzas, gordura e proteína) no filé e no peixe inteiro e os parâmetros sangüíneos
(glicose, triglicerídeos totais, colesterol total e proteínas totais nos dois experimentos e hematócrito no experimento 1) também foram avaliados. No experimento 2 também foi determinado o consumo diário de forragem e a medida instrumental da cor. No experimento 1, houve efeito linear positivo do nível de proteína para todas as variáveis de crescimento. Entretanto, o mesmo efeito foi observado para a
deposição de gordura corporal e no filé, triglicerídeos totais e colesterol total no soro, indicando que a proteína proveniente da dieta estava sendo utilizada como fonte de energia. Para conversão alimentar aparente e gordura no peixe inteiro, o efeito foi quadrático, com ponto de máxima em 40,6% de PB e
37,1%, respectivamente. Coeficiente de retenção protéica, taxa de eficiência protéica, deposição de proteína corporal e no filé e hematócrito também apresentaram efeito linear positivo. No experimento 2, os parâmetros de crescimento não diferiram estatisticamente entre os tratamentos. O consumo de forragem variou entre 1,24 e 2,11% do PV por dia, não diferindo entre os tratamentos. Na composição centesimal do peixe inteiro, maior teor de gordura e menor teor de proteína foram obtidos no tratamento FCG, bem como para cinzas no filé. A dieta FCS foi a que apresentou maiores valores de
proteínas, triglicerídeos e colesterol total circulantes. O rendimento de filé foi maior nos tratamentos FC e FCG, enquanto o índice digestivossomático foi maior nos tratamentos FG e FCG. Na avaliação instrumental da cor, os filés obtidos dos tratamentos FCS e FCG apresentaram maior valor de L (luminosidade), diferindo apenas do tratamento FC. Com base nos resultados obtidos, pode-se concluir
que: o nível mínimo de proteína para o máximo crescimento da carpa capim na fase de recria, com dietas práticas, é de 44%; a variação do nível de proteína da dieta promove alterações no metabolismo dos juvenis de carpa capim, refletido nos parâmetros sangüíneos e de carcaça; farelo de canola e farelo de girassol podem ser utilizados em dietas para recria da carpa capim, quando for feita a suplementação com lisina e forragem, sem comprometer o crescimento.

Previous issue date: 2009<br>A expansão do setor sucroalcooleiro no Brasil tornou-se inquestionável. Desde operíodo colonial, o cultivo da cana-de-açúcar tem sido importante para a economia. Atualmente, sua relevância aumentou com a expansão da atividade, ampliação de mercados e recuperação internacional dos preços do açúcar e aumento das exportações de álcool combustível. As medidas do Programa de Aceleração do Crescimento têmatraído investidores para a região do Triângulo Mineiro que recebe, na época da colheita da cana, milhares de trabalhadores migrantes na microrregião de Frutal-Iturama. Através de estudo exploratório, com base em dados secundários de 2006 a 2008, foi feita a caracterização do setor sucroalcooleiro dessa microrregião e dos seus possíveis reflexos sobre a saúde da população e dos cortadores de cana. A produção de cana, açúcar e etanol cresceu tendo uma força de trabalho, em sua maioria, com emprego temporário, baixa escolaridade, masculina e jovem; sob a exploração e desrespeito aos direitos trabalhistas mais elementares. Em alguns municípios, houve indícios de reflexos das queimadas de cana sobre as taxas de morbi-mortalidade e de internação por doenças cardio-respiratórias. Observou-se a subnotificação dos agravos relacionados ao trabalho e o sub-registro do campo ocupação nas demais notificações. Os resultados obtidos poderão servir como parâmetros para a organização das ações de promoção, assistência e vigilância em Saúde do Trabalhador, e para o fomento das ações interinstitucionais relacionadas a este setor agroindustrial.<br>The expansion of sugar-alcohol sector in Brazil has become unquestionable. Since the colonial period, the cultivation of sugarcane has been significant to the economy. Currently, its importance has increased with the expansion of activity, expansion of markets, international recovery in sugar prices and increased exports of ethanol. The measures of the Program to Accelerate Growth (PAC) have attracted investors to the region of Triângulo Mineiro which receives, at the time of sugarcane harvest, thousands of migrant workers in the micro region of Frutal-Iturama. Through an exploratory study
based on secondary data from 2006 to 2008, the sugar-alcohol sector of this micro region and its possible reflections on the health of both, population and cane cutters, were characterized. The production of cane, sugar and ethanol increased with a work force mostly male, young, with temporary employment, low education and under the exploitation and disrespect of the most basic labor rights. In some municipalities,
sugarcane field burnings were closely linked to the rates of morbidity, mortality and hospitalization due to cardio-respiratory diseases. It was noticed the sub notification of
injuries related to work and sub record of the occupation field in health notifications. The results may be used as parameters in the organization of the promotion, assistance and surveillance in occupational health, and to foment the interinstitutional actions related to this agro-industrial sector.

A diversidade microbiana não foi a mesma para as quatro áreas, mas pode estar mais relacionada aos padrões geográficos do que à aplicação da rocha, mesmo com uma pequena mudança ocorrendo, não pode ser atribuída ao tratamento. Sinais de intemperismo foram notados, mas há dois pontos questionáveis: o tempo para ocorrer este intemperismo, pode ser mais rápido do que se pensava, e a quantidade de minerais intemperizados nesse tempo.

Full textAbstract:
Thesis (PhD(Agric))--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: There is an increasing demand for canola (Brassica napus L.), an emerging oilseed crop in South Africa. Canola thrives in the Western Cape. However, yet low yields are still obtained within the production areas with poor and or variable responses to nitrogen applications. Crop nutrition and specifically the contribution of sulphur (S) to nitrogen (N) use and selection of nutrient efficient genotypes can be strategies of considerable significance in increasing yields.
This study investigated growth, yield and quality responses of canola to different N (0, 30, 60, 90 and 120 kg N ha-1) and S (0, 15 and 30 kg S ha-1) fertilisation rates in field trials at different localities, during the 2009-2011 period. Responses to N and S under optimum growing conditions and responses of different cultivars were investigated in unison in glasshouse trials at the Department of Agronomy of the University of Stellenbosch.
Locality and growing season (year) significantly affected nutrient content in plants at flowering (90 days after planting), dry mass production as well as yield and quality of canola in field trials at five different localities during the 2009-2011 period.
Growth and yield were also affected by N application rate in both field and glasshouse trials. Sulphur applications did not have an effect on vegetative growth, but rather stimulated flower and pod production in glasshouse trials and resulted in higher grain yields in field trials. Response depends largely on rainfall and S content of the soil. Highest yields were, on average, obtained with application rates of 120 kg N and 30 kg S ha-1, while glasshouse trials showed that even higher rates may be considered under optimum growing conditions. High application rates of N and S also improved water use efficiency from approximately 4-5 kg grain yield to about 8-9 kg grain yield mm-1 of rain during the growing season. Agronomic efficiencies of applied N decreases with increasing N rates and values of about 8 kg grain yield increase per kg of N applied at N rates of 120 kg N ha-1 indicated that high N rates may improve profit margins of canola as long as the cost of N is not more than eight times the producers price of canola. Agronomic efficiencies of N applications are improved if 15 kg S ha-1 is applied complimented with high rainfall, but not with applications of 30 kg S ha-1. Improved agronomic efficiencies of S applications shown at higher N rates, confirmed the dependency of S responses to sufficient availability of nitrogen. Sulphur applications, in contrast to N, resulted in an increase in oil content of the grain in field trials.
Yield responses of different cultivars to nitrogen fertilisation under glasshouse conditions differed, with better responses obtained within short and medium season cultivars, than with a late maturing (long season cultivar), in spite of a better vegetative (dry mass) response of the later maturing cultivar. These results may indicate differences in the growth habit of different cultivars, but more research in this regard is needed.<br>AFRIKAANSE OPSOMMING: Canola (Brassica napus L.), ‘n relatief nuwe oilsaadgewas wat goed aangepas is, word in ‘n toenemende mate in die produksiegebiede van die Weskaap verbou. Lae opbrengste en wisselvallige reaksies teenoor stikstofbemesting word egter verkry ten spyte van die gewas se hoë stikstofbehoefte en dit mag moontlik aan swaweltekorte toegeskryf word.
In hierdie ondersoek is die groei-, opbrengs- en kwaliteitsreaksie van canola teenoor verskillende N (0, 30, 60, 90 en 120 kg N ha-1) en S (0, 15 en 30 kg S ha-1) bemestingspeile in droëland proewe op verskillende lokaliteite bestudeer gedurende die 2009-2011 groeiseisoene. Reaksies teenoor N en S onder optimale groeitoestande en vir verskillende cultivars is in glashuisproewe van die Departement Agronomie van die Universiteit van Stellenbosch, uitgevoer.
Die chemiese samestelling van die plante tydens blomstadium (90 dae na plant), asook droëmateriaal produksie, graanopbrengs en kwaliteit het betekenisvol verskil tussen die lokaliteite, maar lokaliteitsverskille is ook deur die seisoene beïnvloed.
Die ontwikkeling, groei en graanopbrengs van die canola is ook beïnvloed deur die stikstofbemestingspeile in beide die veld en glashuisproewe. Swawelbemesting het nie die vegetatiewe groei van canola beïnvloed nie, maar het blom en peulproduksie in glashuisproewe en graanopbrengste in veldproewe verhoog. Die reaksie van canola teenoor die swawelbemesting is grootliks bepaal deur die swawelinhoud van die grond asook klimaatsfaktore soos reënval. In die algemeen is die hoogste canola opbrengste in veldproewe met toedienings van 120 kg N en 30 kg S ha-1 verkry, maar glashuisproewe het getoon dat hoër toedieningspeile nodig mag wees onder optimale groeitoestande soos in besproeiingsgebiede.
Hoë toedieningspeile van N en S het veroorsaak dat die waterverbruiksdoeltreffendheid toegeneem het van 4-5 kg graanopbrengs per mm reën tot sowat 8-9 kg graan opbrengs per mm reën. Agronomiese doeltreffendheid van toegediende stikstofbemesting het afgeneem met toenemende N peile, maar waardes van ongeveer 8 kg opbrengsverhoging per kilogram N toegedien met stikstofpeile van 120 kg ha-1, toon dat hoë N toedieningspeile mag steeds winsgrense verhoog mits die prys van een kilogram N nie meer is as agt maal die produsente prys van canola is nie. Agronomiese doeltreffendheid van stikstofbemesting is verhoog deur ook 15 kg S per hektaar toe te dien, maar nie deur die toediening van 30 kg S ha-1 nie. Die agronomiese doeltreffendheid van S toedienings het slegs by die gelyktydige toediening van hoë stikstoftoedienings toegeneem, wat die wisselwerking tussen N en S ten opsigte van graanopbrengs bevestig. In teenstelling met stikstof het swawel toedienings die olie-inhoud van canola in die veldproewe verhoog.
In glashuisproewe is gevind dat kort en medium groeiseisoen cultivars, ten spyte van ‘n groter vegetatiewe reaksie van die lang groeiseisoen cultivars, groter opbrengsreaksies teenoor stikstof- en swawelbemesting toon. Meer navorsing word egter in hierdie verband benodig.

Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>This work aimed to evaluate the effect of replacing dietary porcine meat meal by different plant-protein sources on the growth, carcass yield, carcass quality, blood parameters and sensory evaluation of the fillets of common carp juveniles. Two experiments were conducted using water re-use system with 15 tanks (280L). In experiment 1, five experimental diets containing plant-protein sources were evaluated (soybean meal - FS, canola meal - FC, sunflower meal - FG and linseed meal - FL) to replace porcine meat meal (FCS - control diet). Common carp juveniles (195, initial weight 43.41g), were randomly distributed in the experimental units, and fed twice daily (09:00 and 15:00) with each of experimental diets, in triplicate. At the end of the trial (71 days), the best growth results were obtained in FCS, followed by FC and FS treatments that did not differ among each other. FCS, FG and FS had the highest values of corporal fat, while FC and FL diets did not show difference. The FL diet showed the worst growth, retention of protein and protein and fat deposition in whole body and fillet. About blood parameters, lower cholesterol was observed in the FG diet and lower aspartate aminotransferase activity was observed in the FL. The other variables did not differ significantly among themselves. Based on the results of experiment 1, the diets of experiment 2 were formulated, which were levels of replacement (0, 25, 50, 75 and 100%) of porcine meat meal by mixing canola meal + soybean meal. The juveniles (135, initial weight 238.05g), were fed 3% of biomass twice daily (09:00 and 15:00). At 18, 36, 54 and 72 days, linear negative effect of plant-protein inclusion for all parameters of growth was observed, except for condition factor. The same result was obtained for whole body fat deposition, fat and protein deposition in fillet and the total cholesterol in serum. Hemoglobin and hematocrit presented quadratic effect. The other measured parameters were not influenced by diets.
Based on this results, we can conclude that a diet based on porcine meat meal provides better growth of common carp juveniles compared to plant-protein based diets, besides
increased protein deposition in whole body and fillet; the carcass parameters (yield and digestive indexes) are not affected by the dietary protein sources; color and taste are not affected by the plant-protein based diets; there is linear negative effect of replacing porcine meat meal by the mixture of canola and soybean meal on the growth of common carp juveniles.<br>O objetivo deste trabalho foi avaliar a resposta de diferentes fontes protéicas de origem vegetal em substituição à farinha de carne suína da dieta, sobre o crescimento, rendimento e qualidade de carcaça, parâmetros sangüíneos e avaliação sensorial dos filés de juvenis de carpa húngara. Foram realizados dois experimentos, utilizando sistema de
recirculação de água com 15 unidades experimentais (280L). No experimento 1, foram avaliadas cinco dietas experimentais. Uma dieta controle (FCS) com apenas farinha de carne suína como fonte protéica e quatro contendo fontes protéicas de origem vegetal (farelo de soja - FS, farelo de canola - FC, farelo de girassol - FG e farelo de linhaça - FL) substituindo 50% da proteína proveniente da farinha de carne suína. Foram utilizados 195 juvenis de carpa húngara (peso médio inicial 43,41g), distribuídos ao acaso nas unidades experimentais, sendo alimentados duas vezes ao dia (9 e 15 horas), em três repetições por tratamento. Ao final do experimento (71 dias), os melhores resultados de crescimento foram obtidos no tratamento FCS, seguido dos tratamentos FC e FS que não diferiram entre si. Para gordura corporal, os tratamentos FCS, FG e FS apresentaram os maiores valores, enquanto as dietas FC e FL não diferiram entre si. O tratamento FL apresentou os piores resultados de desempenho e coeficiente de retenção protéica, bem como as menores deposições de proteína e gordura corporal no filé. Nos parâmetros sangüíneos, menor
colesterol foi observado no tratamento FG e menor atividade de aspartato aminotransferase no tratamento FL. As demais variáveis não diferiram significativamente entre si. Em função
dos resultados do experimento 1, foram formuladas as dietas do experimento 2, que constituíam níveis de substituição (0, 25, 50, 75 e 100%) da farinha de carne suína pela mistura de farelo de canola + farelo de soja. Foram utilizados 135 animais (238,05g de peso médio inicial), que receberam 3% da biomassa em ração, duas vezes ao dia (9 e 15 horas).
Aos 18, 36, 54 e 72 dias, foi observado efeito linear negativo da inclusão de farelos vegetais para todos os parâmetros de crescimento, exceto fator de condição. O mesmo resultado foi
obtido para as deposições de gordura corporal e de gordura e proteína no filé, bem como para o colesterol total no soro. Hemoglobina e hematócrito apresentaram comportamento
quadrático. Os demais parâmetros avaliados não foram influenciados pelas dietas. Com base nos resultados obtidos, pode-se concluir que a dieta à base de farinha de carne suína
proporciona maior crescimento de juvenis de carpa húngara comparada às dietas com farelos vegetais, além de levar a maior deposição de proteína no peixe inteiro e no filé; os
parâmetros de carcaça (rendimentos e índices digestivos) não são afetados pelas fontes protéicas da dieta; A cor, tanto na análise sensorial como por determinação instrumental, bem como o sabor dos filés, não são afetados pelas fontes protéicas de origem vegetal. Há efeito linear negativo da substituição da farinha de carne suína pela mistura dos farelos de canola e soja, sobre o crescimento dos juvenis de carpa húngara.

Abstract
In the Cape Fynbos of South Africa, Psoralea
pinnata (L.) plants occur naturally in both wetland and welldrained
soils and yet effectively fix N2 under the two contrasting
conditions. In this study, nodule structure and functioning
in P. pinnata plants from the two habitats were evaluated using
light and transmission electron microscopy (TEM), as well as
the 15N natural abundance technique. The results showed that,
structurally, fully developed P. pinnata nodules were spherical
in shape with six components (namely, lenticels, periderm,
outer cortex, middle cortex, inner cortex, and a central
bacteria-infected medulla region). Morphometric analysis revealed
44 and 84 % increase in cell area and volume of wetland
nodules compared to those from upland. The percentage
area of nodules occupied by the middle cortex in wetland
nodules was twice that of upland nodules. As a result, the size
of the medulla region in wetland nodules was significantly
reduced compared to upland nodules. Additionally, the average
area of medulla occupied by intercellular air spaces in
wetland nodules was about five times that of upland nodules
(about 431 % increase in wetland over upland nodules). TEM
data also showed more bacteroids in symbiosomes of upland
nodules when compared to wetland nodules. However, isotopic
analysis of above-ground plant parts revealed no differences
in symbiotic parameters such as N concentration, ∂15N and %Ndfa between wetland and upland P. pinnata plants.
These results suggest that, under limiting O2 conditions especially
in wetlands, nodules make structural and functional adjustments
to meet the O2 demands of N2-fixing bacteroids.

Previous issue date: 2015<br>Resumo: A parede celular vegetal é uma estrutura recalcitrante, composta por polissacarídeos complexos que podem ser quebrados em açúcares fermentáveis. A desconstrução desse material complexo pode ser feita por diversos tipos de enzimas hidrolíticas, que são produzidas naturalmente por uma variedade de microrganismos. Entre eles, o fungo Trichoderma reesei se destaca pela capacidade de produzir e secretar estas enzimas em grandes quantidades. Embora alguns trabalhos utilizando abordagens de proteômica e transcriptômica já tenham sido realizados com esse fungo, ainda não são conhecidos em detalhes os mecanismos moleculares responsáveis pela degradação da parede e a regulação gênica envolvida nesse sistema lignocelulolítico. O presente trabalho tem como objetivo principal a análise da expressão gênica global de T. reesei, crescido por 6, 12 e 24 horas em bagaço e colmo de cana-de-açúcar como fontes únicas de carbono, pela técnica de sequenciamento high-throughput de RNA (RNA-Seq). No transcriptoma de T. reesei foram identificadas sendo hiper-expressas as principais celulases, hemicelulases e proteínas acessórias relacionadas direta ou indiretamente com a desconstrução da parede vegetal. De modo geral, as celulases e hemicelulases apresentaram uma expressão maior do que outras enzimas, e o nível dos seus transcritos foi crescente ao longo do tempo tanto em colmo quanto no bagaço. A grande maioria dos genes de CAZymes e proteínas acessórias hiper-expressos foram compartilhados pelos dois substratos, o que demonstra que a estratégia usada por T. reesei para degradar a parede celular do colmo e do bagaço é similar. Adicionalmente, vários fatores de transcrição, proteínas de função desconhecida e transportadores supostamente envolvidos na assimilação dos açúcares liberados também foram hiper-expressos nas condições amostradas. Para validação do RNA-Seq, foi realizado PCR em tempo real de diversos genes hiper-expressos que codificam para enzimas hidrolíticas, reguladores transcricionais, proteínas acessórias e genes ainda não caracterizados. Para isso, a análise temporal foi ampliada para 30 minutos, 2, 4, 6, 12 e 24 horas de crescimento após o inóculo, o que permitiu uma análise mais detalhada da expressão desses genes. Como objetivo secundário, foi analisado o secretoma deste fungo e os açúcares concomitantemente liberados no sobrenadante. Estas análises indicaram que a desconstrução da parede celular já se inicia dentro de 6 horas pós inoculo, com a liberação de monômeros (principalmente xilose e glicose) dos polissacarídeos e secreção de diversas CAZymes. Ensaios enzimáticos também foram realizados, mostrando atividades celulo e hemicelulolíticas. Assim, descrevemos pela primeira vez o arsenal de enzimas transcritas e secretadas por T. reesei RUT C30, desde pontos inicias de crescimento, em bagaço explodido e colmo de cana-de-açúcar. Por fim, este trabalho também permitiu a identificação de vários genes, com função predita ou não, que podem abrir caminho para a descoberta de novos atuantes na resposta do fungo ao substrato lignocelulósico<br>Abstract: Plant cell wall is a recalcitrant structure composed of complex polysaccharides which can be broken down into fermentable sugars. The deconstruction of this complex material can be made by a variety of hydrolytic enzymes which are naturally produced by a variety of microorganisms. Among them, stands out the fungus Trichoderma reesei, able to produce and secrete those enzymes in large quantities. Although some studies using transcriptomics and proteomics approaches have been performed with this fungus, the molecular mechanisms responsible for the degradation of the cell wall and gene regulation involved in this lignocellulosic system are not well known. This work has as main objective the analysis of global gene expression of T. reesei grown at 6, 12 and 24 hours in sugarcane bagasse and culm as sole carbon sources by high-throughput RNA sequencing technology (RNA-Seq). In the T. reesei transcriptome, it was identified the major cellulases, hemicellulases and accessory proteins directly or indirectly related to the deconstruction of plant cell wall. In general, cellulases and hemicellulases exhibited higher expression than other enzymes, and the level of their transcripts was increased over the time in both culm and bagasse cultures. Most of up-regulated CAZymes and accessory proteins were shared between the two substrates, which demonstrates the strategy used by T. reesei to degrade the bagasse and culm cell wall is similar. Furthermore, several transcription factors, proteins of unknown function and transporters supposedly involved in the assimilation of sugars were also up-regulated in the sampled conditions. To validate the RNA-Seq data, real-time PCR of several up-regulated genes encoding hydrolytic enzymes, transcriptional regulators, accessory proteins and proteins not yet characterized was carried out. The time points was extended to 30 min, 2, 4, 6, 12 and 24 hours of growth after inoculation, allowing a more detailed analysis of the expression of these genes. As a secondary objective, T. reesei secretome and the sugars released in the supernatant were analyzed. It was shown that the sugarcane cell wall deconstruction begins within the first 6 hours post inoculation, releasing sugar monomers (mainly xylose and glucose) from polysaccharides due to the secretion of several hydrolytic enzymes. Enzymatic assays were also performed, showing cellulosic and hemicellulosic activities. Finally, this is the first study showing the arsenal of enzymes transcribed and secreted by T. reesei grown on steam exploded sugarcane bagasse and culm, at early time points. It was possible identify several genes, with predicted function or not, that can open new paths to discover novel players on the fungus response to lignocellulosic substrate<br>Mestrado<br>Microbiologia<br>Mestre em Genética e Biologia Molecular

A research report submitted to the School of Social Sciences, Faculty of Humanities of the University of the Witwatersrand in partial fulfilment of the requirements for the degree of Master of Arts in History
04 May 2015<br>This report analyzes the reasons behind the adoption of out growing schemes (sistemas canavieiros) by two Mozambican sugar companies, namely the Companhia do Buzi and the Açucareira de Moçambique as well as the impacts of the companies’ decision on the mills as well as on local communities. Analyzing the adoption of out growing schemes is relevant due to the fact that the Companhia do Buzi and the Açucareira de Moçambique were the only two out of ten Mozambican sugar companies to collaborate with out growers. All the out growers were Portuguese citizens or ‘civilized’ Africans. The report also analyses the reasons and the impacts of the collapse of those schemes in the early post-colonial period. The report argues that the mills adopted out growing schemes to face the long term shortage and increasing costs of African agricultural labour. This strategy solved their problems but left the out growers indebted and frustrated and local communities dispossessed. On the collapse of the out growing schemes, the report argues that it resulted from the increasing lack of economic feasibility of sugar cane growing, which was a result of economic crisis and the authorities’ hostility towards the out growers.

Following concerns expressed by canegrowers in the Burdekin River Irrigation Area (BRIA) of Northern Queensland regarding rising groundwater and salinity the Department of Primary Industries instigated action to investigate and develop Best-On-Farm Water Management Practices. The purposes of this project were to improve landholder awareness of water use to maximise cane production while minimising the likelihood of salinity and changes in the groundwater balance, and to facilitate the development of soil and water management practices on a range of soils in the BRIA. The project lasted for 12 months, and this short duration affected research methodologies and techniques selected. Groups of farmers were organised, participation was good and useful outcomes resulted. These included: improved landholder awareness of the relationships between salinity, water use and groundwater; identification of a range of best practices; identification of social theories about water management practices; development of an extension model based on the value of indigenous knowledge; equality between government and farmers; examination of underlying assumptions in relation to water management by both government and farmers; identification of issues for future research and extension.

No<br>Existing research on the impact of growing up in care focuses upon either the care experience itself or the period of transition from care to independence. Our knowledge of outcomes largely ceases when former residents of the care system reach their early twenties. There are strong social justice reasons for extending research into the older adult lives of such young people. We know a great deal about the multiple disadvantages that such individuals face as children. But research is largely silent about their subsequent adult lives. While we must be cautious in drawing causal links to the childhood care experience as the time period since life in care extends, we know that early experiences can affect care-leavers across their life coursejust as childhood experience affects all adults in a variety of ways. In this review, we highlight evidence drawn from research in Australia, the United Kingdom, Canada, Ireland, and the United States, with particular attention paid to the first two of those countries. We use a wide range of sources and identify areas for further consideration, including access to personal records, mental health, education, and parenting. By doing so, we seek to open up this area for further research with the hope that such research will lead to an increasing recognition of care-leavers' needs and thus to improvements in social policy and service provision.

Men’s grooming has become an attractive and lucrative, yet challenging market within the
personal care industry. Given men’s ever more sophisticated grooming routine, companies are
faced with the necessity of adjusting to local adaptations and trends.
The current study therefore chose to focus on an analysis of men’s grooming habits and routines
in Austria. The findings suggest that companies should focus on the skin care sector, as it offers
a variety of growth opportunities. Furthermore, the male consumer decision journey has
developed into a complex cycle. Therefore, implementing targeted marketing activities and
providing information for decision-making to trigger needs are essential to capture the
consumer.
