Planning food services for a campus setting 总被引:1,自引:0,他引:1
Kenneth J. Klassen Elzbieta Trybus Arundhati Kumar 《International Journal of Hospitality Management》2005,24(4):579-609
Providing appropriate food services in a campus setting is increasingly important due to more demanding customers and because clients have less time to go off-campus when they need to eat. Using a university campus as an example, this research looks at customer satisfaction with existing food services and explores various methods for determining where to locate new facilities. This campus currently has great needs for additional food services, and it is shown clearly where additional food services are required. Also, the methods used are compared in terms of their effectiveness in finding the solution. 相似文献

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses. 相似文献

The National Economic Association introduced the W. Arthur Lewis Distinguished Lecture series in December 1985 at the Allied
Social Sciences Association meetings in New York City. The Lewis Lecture is named in honor of the 1979 Nobel Laureate in Economics,
much of whose research has been devoted to the problem of Third World economic development. In the same spirit, the Lewis
Lectures are intended to explore the themes of global inequality. Third World poverty, and prospects and possibilities for
change. The inaugural Lewis address was delivered by Lance Taylor, professor of economics and nutrition at the Massachusetts
Institute of Technology. Taylor, an immensely creative economist, has led contemporary development economists in the analysis
of disparities in the structural relationships between Northern (that is, more-developed) and Southern (that is, less-developed)
countries. Taylor’s subject matter, “Trade and Growth,” constituted both a provocative assessment of the stale of knowledge
in this area and a compelling indictment of the insights offered by conventional economics. Taylor’s address, presented December
28, 1985, provides a sterling beginning to what promises to be an important lecture series. 相似文献

Employment,schooling and productivity growth 总被引:1,自引:1,他引:0
Summary This paper presents an empirical analysis of labour demand and labour productivity growth in The Netherlands. Assuming an aggregate production function with as factors capital and 3 types of labour, distinguished by educational attainment, cost minimization leads to a set of 3 labour demand relations to be estimated on time series data. Using the estimates and the implied elasticities, aggregate labour productivity growth is decomposed into factor substitution, autonomous factors, labour time shortening, economies of scale, utilization rates and the increased educational level of the working population. The contributions of substitution, utilization rates and education appear to be substantial, notably in the seventies.

The various agricultural practices employed in eastern Maputaland are described.
Agricultural strategies utilized in Maputaland are low in productivity but aim to minimize risk. The area is marginal for agriculture as soils are sandy and rainfall unreliable. Insects and plant diseases accentuate the problem. Infrastructure is lacking in the area. Traditional agricultural systems predominate.
Farming in the area is generally of a subsistence nature and can be divided into gardening, swamp farming and field cropping. Steps towards modernization of agriculture must take into account all existing constraints. 相似文献
