Summary.  Social science applications of sequence analysis have thus far involved the development of a typology on the basis of an analysis of one or two variables which have had a relatively low number of different states. There is a yet unexplored potential for sequence analysis to be applied to a greater number of variables and thereby a much larger state space. The development of a typology of employment experiences, for example, without reference to data on changes in housing, marital and family status is arguably inadequate. The paper demonstrates the use of sequence analysis in the examination of multivariable combinations of status as they change over time and shows that this method can provide insights that are difficult to achieve through other analytic methods. The data that are examined here provide support to intuitive understandings of clusters of common experiences which are both life course specific and related to socio-economic factors. Housing tenure is found to be of key importance in understanding the holistic trajectories that are examined. This suggests that life course trajectories are sharply differentiated by experience of social housing.  相似文献

Standard decision theoretic models disregard the phenomenon of interpersonal dependency of preferences. In this paper it is argued that interpersonal dependency of preferences is a serious challenge for standard utility theory. First we sketch the more philosophical aspects of the problem and then, using a simple, formal model for the two-person case, we show that interpersonal dependency of preferences generally results in indeterminacy of preferences (resp. of subjective utility).  相似文献

Tactical production-distribution planning models have attracted a great deal of attention in the past decades. In these models, production and distribution decisions are considered simultaneously such that the combined plans are more advantageous than the plans resolved in a hierarchical planning process. We consider a two-stage production process, where in the first stage raw materials are transformed into continuous resources that feed the discrete production of end products in the second stage. Moreover, the setup times and costs of resources depend on the sequence in which they are processed in the first stage. The minimum scheduling unit is the product family which consists of products sharing common resources and manufacturing processes. Based on different mathematical modelling approaches to the production in the first stage, we develop a sequence-oriented formulation and a product-oriented formulation, and propose decomposition-based heuristics to solve this problem efficiently. By considering these dependencies arising in practical production processes, our model can be applied to various industrial cases, such as the beverage industry or the steel industry. Computation tests on instances from an industrial application are provided at the end of the paper.  相似文献

The purpose of this paper is to describe and illustrate with case examples a brief intervention termed Radical Exposure Tapping (RET). RET can be integrated with family therapy to address stuck points where the therapy is hindered by a family member's affective block, an intense and unchangeable emotional reactivity to a specific trigger. RET draws from the methodology of Eye Movement Desensitization and Reprocessing (EMDR) and combines it with the tapping sequence of the Emotional Freedom Technique (EFT) to produce an intervention that is more flexible than EMDR, provides greater rigor than using the EFT technique alone and can be effective in a single session within the context of family therapy. The paper puts this work into context by first over viewing definitions of trauma and Post‐Traumatic Stress Disorder, arguing that family members' emotional reactivity may be a symptom of PTSD even when they would not qualify for the diagnosis because they had not experienced a life threatening event.  相似文献

产品市场竞争程度对企业融资行为的影响   总被引:1,自引:0,他引:1  
许多研究表明我国上市公司存在较强的股权融资偏好。国内学者根据代理理论认为股权融资过多的企业未能充分利用财务杠杆而使企业绩效下降,而本文主要从产品市场竞争对资本结构影响这一角度来研究上市公司的融资行为。研究发现,上市公司的股权融资偏好和上市公司治理结构不完善、代理问题严重等体制和政策因素有关,但是,激烈的产品市场竞争也是导致企业采用低财务杠杆的重要原因,而且由于这一原因而导致的财务保守行为是合理的,它是企业为避免财务风险提高产品市场竞争能力而采取的战略行为。  相似文献

通过对江苏3个县区588户农户问卷调查,了解处于不同经济发展水平的苏北、苏中、苏南农户信贷需求的特征,比较三个地区在贷款用途、融资渠道、融资偏好等方面的差异性。研究发现信贷需求数量与农户收入具有显著的负相关性:苏北农户信贷需求的频率最高,但借款金额相对较小,大多是消费性用途;苏中农户信贷需求的频率相对较低,但借款金额较大,贷款主要用于生产性用途;苏南农村已经完全城市化,信贷需求主要是消费性用途。三个地区农户的融资渠道都明显表现为以民间融资为主的特征。从总体样本的融资选择次序看,第一选择是亲戚朋友借款,第二选择是银行,第三选择是信用社,最不情愿的选择是高利贷。建议加快农村金融机构改革,引进新型的小额贷款机构和其它金融机构,满足农户多样化和差异性的金融需求。  相似文献

Abstract

Personality trait theories are often used to identify particular personality or behavioural characteristics of potential employees by human resource management departments. However, this can be enhanced by understanding how motivation plays a role in personality, and particularly within the context of knowledge-based personality processes. The paper draws on knowledge management theory called Knowledge Profiling (KP) in which a theoretical construct has been developed representing personality through a set of three traits and their polar values. This model has previously been linked to the trait theory of personality called Myers-Briggs Type Indicator (MBTI). This research adopts KP, develops its linkage with MBTI, and elaborates on its connection with motivation. The resulting model, referred to as Knowledge Profiling Motivational (KPM) model, is developed by connecting it with the Work Preference Inventory (WPI), which assesses individual differences in Intrinsic and Extrinsic motivational orientations. Analysis indicates that KPM is an improvement on the KP model in representing personality. Moreover, the research suggests that personality traits are not limited to a bipolar relationship but that there are relationships between traits as well.  相似文献
