People with disability are particularly exposed to poor living conditions: on one hand they have more difficulties in getting
an income cause to their inabilities, on the other hand conditions of poverty increase the risk of disability. However, little
rigorous quantitative research has been undertaken to measure the real impact of disability on poverty. Methods based on monetary
set (income and consumption) may not reflect the real possibility to convert resources into the fulfilment of personal goals.
The capability approach, developed by A. K. Sen, offers a useful framework for the evaluation and assessment of individual
well-being considering both monetary and non-monetary resources. The study describes a methodology, derived from the capability
approach, to estimate the additional income needed for various types of household with and without disabled members to ensure
the same satisfaction with economic resources. The method has been applied to the Italian contest, where 2.6 million people
with disability live, and then the results are compared with the findings from an analogous study conducted in UK. The study
reveals that disabled people in Italy need an income level two times higher to enjoy the same level of economic satisfaction,
while in UK 50% of extra resource are sufficient. The findings suggests that traditional evaluations based on consumption
lead to an underestimation of the needs of household containing disabled members. It follows that the financial benefits envisaged
by actions planned by government through current instruments may not be completely effective. 相似文献

Infant and youth mortality fell steeply between the Unification of Italy and the 1930s, particularly due to the decline in infectious and parasitic diseases. A number of mortality crises, however, at times halted this decline: the 1908 Calabria-Sicily earthquake, the 1915 Marsica earthquake, World War I and 1918 Spanish INFLUENZA outbreak.This paper focuses as the repercussions of these events on the general survival status of young people from birth to puberty, as well as the main pathologies responsible for the rise in mortality.An analysis of differences in mortality according to sex during the various crises was also performed to ascertain whether the more difficult survival conditions during these periods affected males and females equally. 相似文献

This paper is an attempt to place the forecasting of socio-political variables in the context of actual information needs of industrial companies. Initially discussion is of the effect of socio-political variables upon companies with a review of this significance for decision makers and decision takers. An attempt is then made to categorise existing forecasting techniques in the context of socio-political data whilst regard is paid to the possible effects of socio-political variables on companies. Discussion is then broadened to a consideration of current practice both in the UK and in the USA. Problems implicit in current practice are commented upon and the paper ends with the conclusion that socio-political forecasting is currently significant to many companies and that there is a major potential role for management scientists to play in the development and implementation of appropriate techniques. 相似文献

Fossil fuels are an important source of energy for Ontario Hydro and purchases exceed $100 million per year. This paper describes a computer simulation of the inventory situation over an eight-year period, which is being used to assess the relationship between order flexibility and the target carry-over stocks at the beginning of each shipping season. A simple way of presenting the results for management evaluation is illustrated. Variations of the model are used to assess random influences, such as strikes, and to determine the economic balance between holding costs and stock-outs. 相似文献

The findings reported result from a questionnaire survey, and a number of company interviews. Further questions which need to be answered are identified, and a research project to provide these answers is outlined. 相似文献

The measurement of labour turnover is important both because high turnover is regarded as a sign that something is wrong in a firm and also because quantitative information is important in planning recruitment programmes. This paper describes a statistical technique which has proved useful for the measurement and prediction of turnover. 相似文献

A graph class is sandwich monotone if, for every pair of its graphs G

}) belongs to the class for every i between 1 and k. In this paper we show that strongly chordal graphs and chordal bipartite graphs are sandwich monotone, answering an open
question by Bakonyi and Bono (Czechoslov. Math. J. 46:577–583, 1997). So far, very few classes have been proved to be sandwich monotone, and the most famous of these are chordal graphs. Sandwich
monotonicity of a graph class implies that minimal completions of arbitrary graphs into that class can be recognized and computed
in polynomial time. For minimal completions into strongly chordal or chordal bipartite graphs no polynomial-time algorithm
has been known. With our results such algorithms follow for both classes. In addition, from our results it follows that all
strongly chordal graphs and all chordal bipartite graphs with edge constraints can be listed efficiently. 相似文献
