An explorative study of the technology transfer coach as a preliminary for the design of a computer aid

Jönsson, Oscar January 2014 (has links)
The university technology transfer coach has an important role in supporting the commercialization of research results. This thesis has studied the technology transfer coach and their needs in the coaching process. The goal has been to investigate information needs of the technology transfer coach as a preliminary for the design of computer aids.Using a grounded theory approach, we interviewed 17 coaches working in the Swedish technology transfer environment. Extracted quotes from interviews were openly coded and categorized. The analysis show three main problem areas related to the information needs of the technology transfer coach; awareness, communication, and resources. Moreover, 20 features for future computer aids were extracted from the interview data and scenarios and personas where developed to exemplify the future use of computer aids.We conclude that there is a need for computer support in the coaching process. Such systems should aid the coach in; awareness, aiding the coach to focus on meetings; communication, aid the coach to transfer commercialisation knowledge; and resources, aid the coach in accessing and delivering of resources to the coachee. However, it is imperative that the computer aids do not interfere with the coach current process; and that the computer aid is not seen as the sole solution.

Efeito do manejo do solo com plantas de cobertura, cultivares/híbridos e nitrogênio na cultura do milho / Effect of soil management with soil cover plants, hybrids and dose of nitrogen in the productivity of corn

No. of bitstreams: 1 RENATA ALVES DE AGUIAR.pdf: 291282 bytes, checksum: 84c3b9b16001171ff6f54a0c449179a7 (MD5) Previous issue date: 2008-02-26 / The corn is the main cereal produced in Brazil and its productivity is very affected by the improper use of nitrogen, which is the nutrient absorbed in larger quantities and therefore responsible for a significant share in production costs. Due to the importance of nitrogen for the corn crop becomes necessary studies to reduce the amount of nitrogen applied to the crop, reducing losses and increasing the efficiency of its use, beside minimize environmental risks. One way have been studied to reduce the amount of nitrogen applied and increase the efficiency of use of inorganic nitrogen, from the fertilizer, it is the combination of plants that cover the ground with nitrogened fertilizer. The study aimed to determine the economic viability and the effect of soil management with the use of soil cover plants, hybrids and nitrogen doses in coverage in the vegetative and reproductive characteristics, related to productivity of corn. The corn, in the experiment, was planted at begning of February in the field trial of Embrapa Arroz e Feijão, Red Latosol Distrophic. The experimental design was a randomized complete block with three replicates the arrangement of plots in sub-sub-divided. The plots were formed by four types of soil management: direct planting of corn on the black mucuna stubble (Mucuna aterrima Merr.); direct planting of corn on the of crotalária juncea stubble (Crotalaria juncea L.); direct planting of corn on vegetation spontaneous (aside) and planting corn in the system of conventional tillage (arado of aiveca). The subplots were formed by five doses of nitrogen in coverage: 0, 45, 90, 180 and 360 kg ha-1 of nitrogen in coverage, and the sub-sub-plots of four hybrids of corn: BRS 3003, AG 1051, Green Corn HT-1, HT-2 Green Corn. The analysis of the benefit / cost was performed on the basis of prices of materials and services raised in April 2007. The benefit / cost in the various systems was held in the Excel spreadsheets, and economically viable a relationship exceeding 1.0. It was concluded that: there is effect of hybrid and soil management on vegetative characteristics such as plant height and the first spik and on productive characteristics as income from pulp and grain and mass in a thousand grains of corn, and there is no interaction between hybrid, soil management and dose of nitrogen in coverage of the productivity of corn. The best soil management as the benefit / cost is the fallow without any addition of nitrogen in coverage, followed by the system of conventional tillage with 45 kg ha-1 and without the addition of nitrogen. / O milho é o principal cereal produzido no Brasil e sua produtividade é bastante afetada pelo uso inadequado do nitrogênio, que é o nutriente absorvido em maiores quantidades e, portanto responsável por uma parte significativa nos custos de produção. Devido à importância do nitrogênio para a cultura do milho torna-se necessário estudos para otimizar a quantidade e a forma de aplicação deste nutriente a fim de reduzir perdas e aumentar a eficiência da sua utilização, além de minimizar os riscos ambientais. Uma das formas que vem sendo estudada para reduzir a quantidade de nitrogênio aplicada e aumentar a eficiência de utilização do nitrogênio inorgânico, proveniente dos fertilizantes, é a associação de plantas de cobertura do solo com o fertilizante nitrogenado. O trabalho teve como objetivo verificar a viabilidade econômica e o efeito do manejo do solo com a utilização de plantas de cobertura, cultivares/híbridos e doses de nitrogênio em cobertura nas características vegetativas e reprodutivas, relacionadas a produtividade do milho. O experimento foi conduzido com milho safrinha no campo experimental da Embrapa Arroz e Feijão, em Latossolo Vermelho Distrófico. O delineamento experimental utilizado foi o de blocos ao acaso com três repetições em arranjo de parcelas sub-sub-divididas. As parcelas foram formadas por quatro tipos de manejo do solo: plantio direto do milho sobre palhada de mucuna preta (Mucuna aterrima Merr.); plantio direto do milho sobre palhada de crotalária juncea (Crotalaria juncea L.); plantio direto do milho sobre vegetação infestante (pousio) e plantio do milho no sistema de preparo convencional (arado de aiveca). As subparcelas foram formadas por cinco doses de nitrogênio em cobertura: 0, 45, 90, 180 e 360 kg ha-1 de nitrogênio/uréia em cobertura; e as sub-sub-parcelas por quatro cultivares/híbridos de milho: BRS 3003, AG 1051, Milho Verde HT-1, Milho Verde HT-2. A análise da relação benefício/custo foi realizada com base em preços de materiais e serviços levantados em abril de 2007. A relação benefício/custo nos diferentes sistemas foi realizada em planilhas do excel, sendo viável economicamente uma relação superior a 1,0. Concluiu-se que: Existe efeito da cultivar/híbrido e do manejo do solo sobre características vegetativas como altura de plantas e da primeira espiga e sobre características produtivas como rendimento de polpa e de grãos e massa de mil grãos de milho; e não há interação entre cultivar/híbrido, manejo do solo e dose de nitrogênio em cobertura na produtividade do milho. O melhor manejo do solo quanto a relação benefício/custo é o pousio sem nenhuma adição de nitrogênio em cobertura, seguido do sistema de preparo convencional com 45 kg ha-1 e sem adição de nitrogênio.
