Holistic trajectories: a study of combined employment, housing and family careers by using multiple-sequence analysis

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.

Interpersonal dependency of preferences

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).     

Tactical production and distribution planning with dependency issues on the production process

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.     

Deactivating the Buttons: Integrating Radical Exposure Tapping with a Family Therapy Framework

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.     

流动人口居留意愿内部分化研究——以温州市为例

利用2009年在温州市进行的人口结构变化专项调查资料,将流动人口作为一个非均质的整体进行研究,采用数据交叉分析方法,分析了流动人口内部在居留意愿上的分化,并对流动人口居留意愿的影响因素进行了多分类的logistic回归分析。结果表明,大部分流动人口尚未有在流入地长期居留的打算,但滞留趋势明显;打算最终返乡的流动人口比例较高,非永久居留是一种常态化的现象;流动人口内部在居留意愿上存在明显分化。结合以上分析,讨论了流动人口居留意愿分化对制定流动人口政策和选择城市化战略等方面的思考。     

政府偏好与制度起源:以1950年代后的收容遣送政策为例

尽管学术文献里没有给出政府偏好的恰当定义,但它的确是解释中国制度变迁中的一个重要变量。运用制度学派的有关制度变迁理论,对收容遣送制度起源的历史作出政治学的解释,可以认为,巩固政权以及与此相联系的城市化与工业化的双重压力,都对政府治理城市秩序的偏好产生了重大影响。1950年代以后的收容遣送政策及其实践,为考察政府偏好与制度设计之间的关联提供了生动的素材。     

试论日本航运技术创新中的官民协作

技术创新是航运发展的主要动力。战后,日本政府和航运业界在焊接技术、大型船技术、高速船技术、船舶自动化技术和经济型船技术等航运技术创新方面紧密协作,从而使日本改变了战后初期航运技术落后的局面,并紧跟世界航运发展潮流,甚至走在前列。其经验值得我们借鉴。
