Emitter spacings of 0.3 to 0.6 m are commonly used for subsurface drip irrigation (SDI) of corn on the deep, silt loam soils of the U.S. Great Plains. Subsurface drip irrigation emitter spacings of 0.3, 0.6, 0.9 and 1.2 m were examined for the resulting differences in soil water redistribution, corn grain yield, yield components, seasonal water use, and water productivity in a 4‐year field study (2005 through 2008) at the Kansas State University Northwest Research‐Extension Center, Colby, Kansas. The results indicate that there is increased preferential water movement along the dripline (parallel) as compared to perpendicular to the dripline and that this phenomenon partially compensates for wider emitter spacings in terms of soil water redistribution. Corn yield and water productivity (WP) were not significantly affected by the emitter spacing with application of a full irrigation regime

In the ornamental plant production region of Girona (Spain), which is one of the largest of its kind in southern Europe, most of the surface is irrigated using wide blocked-end furrows. The objectives of this paper were: (1) to evaluate the irrigation scheduling methods used by ornamental plant producers; (2) to analyse different scenarios in order to assess how they affect irrigation performance; (3) to evaluate the risk of deep percolation; and (4) to calculate gross water productivity. A two-year study in a representative commercial field, planted with Prunus cerasifera ‘Nigra’, was carried out. The irrigation dose applied by the farmers was slightly smaller than the required water dose estimated by the use of two different methods: the first based on soil water content, and the second based on evapotranspiration. Distribution uniformity and application efficiency were high, with mean values above 87%. Soil water content measurements revealed that even at the end of the furrow, where the infiltrated water depth was greatest, more than 90% of the infiltrated water was retained in the shallowest 40 cm of the soil; accordingly, the risk of water loss due to deep percolation was minimal. Gross water productivity for ornamental tree production was € 11.70 m–3, approximately 20 times higher than that obtained with maize in the same region

O estudo da motivação no trabalho bem como dos seus determinantes têm-se assumido de grande importância para os vários domínios da psicologia organizacional. Com este estudo pretende-se analisar a relação entre a motivação e a produtividade, assim como a relação destas com algumas variáveis individuais (sexo, idade, estado civil, habilitações literárias), e com a variável situacional antiguidade na tarefa. Para avaliar a motivação foi utilizada a escala MULTI MOTI de Ferreira et. all, 2006, que contem 28 itens avaliando 4 dimensões da escala referentes à motivação no trabalho (organização no trabalho, desempenho nas tarefas, realização e poder, motivação do envolvimento). Utilizou-se uma amostra de 117 colaboradores de um call center, com idades compreendidas entre 18 e 56 anos (M=24,23; DP=7,665).

Whatever the other characteristics of the universal museum, education must be one of its core functions. That is, education both of regular visitors and those who are not but who are members of the local, regional or national communities served by the museum. In this sense, universal refers to making the museum accessible to all: accessible physically and intellectually. This relates to what I mean by education. It is far broader than what takes place between teachers and pupils in a formal setting. Education is also about providing environments where people will be inspired or provoked to know, to question. To reflect about themselves and the wider human and natural world. A universal museum should be a great facilitator of these learning processes. In this paper I shall focus on five ways in which there can be integration of educational opportunities in the universal museum. For examples to illustrate these themes I shall draw on practices in a small sample of museums in Europe and the USA.
