福建省居民潜在国内出游力的地区差异综合评判 总被引:1,自引:0,他引:1
用可拓工程方法和主成份分析方法建立了福建省居民潜在国内出游力的综合评判物元模型,结果表明福建省居民国内出游力的地区差异大。综合评判得出福建省国内居民潜在出游力强弱可划分为4个不同级别;单指标测定出了各地区影响出游力的优劣势,为旅游供给者有针对地市场推广和发挥有限资金效用提供科学证据。 相似文献

遗传算法是解决车间调度问题的有效方法之一。但在构造适应度函数时由于调度问题诸多的束条件使得直接求解十分困难。罚函数法将约束条件加到目标函数上,变有约束为无约束.能较易求解该类问题。 相似文献

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields
such as organizational science, management science and economics and have long recognized that classification offers an approach
for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities).
However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific
research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate
the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational
classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they
fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity.
This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational
classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms
and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics)
are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic
classification approach for inferring and representing the historical relationships underpinning organizational diversity.
This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently,
this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification
of organizational diversity. 相似文献

Ulrik Kihlbom 《Journal of Risk Research》2018,21(2):222-235
A conceptual truth about risks is that they involve a possible and future adverse effect or a negative value of some kind. The genetic risks that individuals may face in the health care setting differ in some crucial respects to other kind of risks. The aims of this paper are to analyse the notion of value in the context of genetic risk in the setting of health care, and to suggest a conception of the evaluative aspect of genetic risk that is fruitful for genetic risk information. Two influential and relevant approaches to value, preferentialism and the capability approach, are discussed in the light of certain distinctive features of genetic risk and a third, a sensibility theory of value is suggested. According to this view, the concept of risk is a so-called ‘thick’ evaluative concept that has both a world-guiding function as well as an action-guiding or normative function. It is argued that this provides a more promising way to think about genetic risks in the clinical setting. 相似文献

This study investigates the antecedents and consequences of organization‐level inclusion climate. A national sample of human resource decision‐makers from 100 organizations described their firms' formal diversity management programs; 3,229 employees reported their perceptions of, and reactions to, their employers' diversity management. Multilevel analyses demonstrate that identity‐conscious programs (programs that target specific identity groups) generate an inclusion climate. Moreover, the analyses provide evidence of multilevel mediation: In organizations with an inclusion climate, individual employees perceive the organization as fulfilling its diversity management obligations and respond with higher levels of affective commitment. This study represents an important step toward understanding how a shared perception of organizational inclusiveness develops and how inclusion climate facilitates the achievement of diversity management objectives. The findings also shed light on the important role of identity‐conscious programs in promoting organizational commitment within a diverse workforce. 相似文献

新疆南北疆沙产业发展差异性及对经济、环境影响研究 总被引:1,自引:0,他引:1
研究新疆沙产业区域发展差异性,分析沙产业发展与环境、经济的关系,对加深社会以及相关部门对沙产业的认识具有一定促进作用,也能够一定程度上促进沙产业本身的良性发展。文章选取环塔里木盆地-塔克拉玛干沙漠区域的和田地区与环准噶尔盆地-古尔班通古特沙漠区域的26个县市(兵团)作为主要研究对象,数据来源为实地调查、新疆统计年鉴及新疆各地2013年统计公报等,筛选出当地沙产业发展、经济发展及环境状况的10个具有代表性的指标;运用因子分析、聚类分析等多元统计方法,对调查区26个不同区域的沙产业发展进行了综合评价与分类比较;采用多元线性回归方法,分析了沙产业发展与环境、经济之间的相互关系。研究结果表明:在对经济影响方面,沙产业发展能够轻微改善环境,显著拉动经济;在沙产业发展格局方面,存在"北强南弱"、均衡性不足的问题;在分析沙产业前期发展现状方面,存在"挤出效应"、效益未充分体现的问题;在对比南北疆发展现状方面,存在北疆沙产业发展赶超南疆、后发优势明显的现象。并针对性提出具体的政策建议,即从应对区域发展均衡性不足方面,因地制宜,发展特色沙产业;从削弱"挤出效应"方面,加大科技创新投入,合理规划投资规模;从促进沙产业区域发展方面,扩大北疆后发优势,谋求南疆先发效应。通过该文的研究,能够一定程度消除社会对新疆沙产业发展的认识误区,同时对策建议是基于现实存在的问题而提出的,在解决相关问题上具有一定的现实意义。 相似文献
