Indicators encompassing the multidimensional nature of sustainability (economic, environmental and social) are developed here using Irish National Farm Survey data over an 11-year period (1996–2006). This is the first such study undertaken for Ireland, and the results show significant change over the decade in all three areas examined. The general concept of sustainability is discussed and the development of agricultural sustainability indicators in an Irish context is described. Individual indicators are dealt with in turn, and the RERC SMILE model is used to demonstrate how these indicators can be derived at a spatial level below the national scale. Economic viability was found to be generally in decline over the 10-year period examined. However, when individual farming systems were taken into account, some were found to perform better than others. From an environmental perspective, the more intensive farming systems (primarily dairy) were found to pollute more on average, while in more general terms the levels of methane emissions produced per hectare have been falling over the reference period. Results also indicate that rural Ireland is experiencing a period of fundamental change in terms of the demographic viability of its farming community.  相似文献

Jim Ramsay was born on September 5, 1942, in Prince George, British Columbia. He pursued undergraduate studies at the University of Alberta, where he completed a BEd in 1964 with a major in English and a minor in mathematics. He then specialized in statistics and psychometry, earning a PhD in psychology from Princeton University in 1966. After holding a temporary lectureship in the Department of Psychology at University College London for one year, he joined the Department of Psychology at McGill University, where he rose through the academic ranks. He was chair of his department from 1986 to 1989 and spent sabbatical leaves in Cambridge, Grenoble, and Toulouse. He was named professor emeritus upon his retirement in 2007. Jim is the author of four influential books and over 100 peer‐reviewed articles in statistical and psychometric journals. He developed much of the statistical theory behind multidimensional scaling and is widely recognized as the founder of functional data analysis. Three of his papers were read to the Royal Statistical Society, and another won The Canadian Journal of Statistics 2000 Best Paper Award. The Statistical Society of Canada (SSC) awarded him a Gold Medal for research in 1998 and an honorary membership in 2012. Jim was president of the Psychometric Society in 1981–82 and president of the SSC in 2002–03. The following conversation took place at Jim's home in Ottawa, Ontario, on March 14 and April 4, 2012.  相似文献

In the currently rapidly changing business world, innovation has not only become the key to survival and success, but also the defining challenge of organisations. For latecomer firms, however, because of their inherent resource constraints, innovation has become a far more complex undertaking, similar to a multidimensional puzzle. Although there have been an increasing number of practitioner-based surveys, a discrepancy still remains between academia and industry concerning the role and importance of R&D in innovation. Therefore, this study carried out an industry–university–institution survey of Taiwan, based on a multidimensional framework of the innovation puzzle: human, R&D, flow and connection. The results reveal several interesting clues and provide a better understanding of the innovation puzzle for latecomers, and more importantly, resolves the puzzle that could help latecomers identify where new opportunities lie and what weaknesses they must strengthen.  相似文献

This paper analyses managers' moral decision-making, and studies the role of ethical theories in it by following the research tradition using the multidimensional ethics scale. The research question is: what kinds of ethical dimensions do Finnish business managers reveal when they are making moral decisions, and how have these dimensions changed in the 1990s? This question is answered by examining what kinds of factors emerge when the multidimensional ethics scale is used to analyse Finnish managers' attitudes toward moral dilemmas. The results show that Finnish managers' decision-making reflects a variety of ethical theories. Teleological thinking is strongly emphasised by Finnish managers, and relativist thinking is used as well, but often combined with either deontology or justice thinking. In addition, a strong moralistic dimension emerged in Finnish managers' decision-making. The analysis was carried out in two different surveys in years 1994 and 1999, and the results show that the ways of decision-making were more complex at the end of the 1990s than almost six years earlier.  相似文献

This paper deals with multidimensional dynamic risk measures induced by conditional g‐expectations. A notion of multidimensional g‐expectation is proposed to provide a multidimensional version of nonlinear expectations. By a technical result on explicit expressions for the comparison theorem, uniqueness theorem, and viability on a rectangle of solutions to multidimensional backward stochastic differential equations, some necessary and sufficient conditions are given for the constancy, monotonicity, positivity, and translatability properties of multidimensional conditional g‐expectations and multidimensional dynamic risk measures; we prove that a multidimensional dynamic g‐risk measure is nonincreasingly convex if and only if the generator g satisfies a quasi‐monotone increasingly convex condition. A general dual representation is given for the multidimensional dynamic convex g‐risk measure in which the penalty term is expressed more precisely. It is shown that model uncertainty leads to the convexity of risk measures. As to applications, we show how this multidimensional approach can be applied to measure the insolvency risk of a firm with interacting subsidiaries; optimal risk sharing for ‐tolerant g‐risk measures, and risk contribution for coherent g‐risk measures are investigated. Insurance g‐risk measure and other ways to induce g‐risk measures are also studied at the end of the paper.  相似文献
