Cumulative correspondence analysis of ordered categorical data from industrial experiments

Most studies of quality improvement deal with ordered categorical data from industrial experiments. Accounting for the ordering of such data plays an important role in effectively determining the optimal factor level of combination. This paper utilizes the correspondence analysis to develop a procedure to improve the ordered categorical response in a multifactor state system based on Taguchi's statistic. Users may find the proposed procedure in this paper to be attractive because we suggest a simple and also popular statistical tool for graphically identifying the really important factors and determining the levels to improve process quality. A case study for optimizing the polysilicon deposition process in a very large-scale integrated circuit is provided to demonstrate the effectiveness of the proposed procedure.

Negotiated identities: Male migration and left-behind wives in India

This paper examines the impact of husbands’ migration on the lives of women left behind. Using data from the India Human Development Survey 2005, we focus on two dimensions of women’s lives: women’s autonomy and control over their lives; and women’s labour force participation. Results suggest that household structure forms the key mediating factor through which husbands’ absence affects women. Women not residing in extended families are faced with both higher levels of responsibilities and greater autonomy, while women who live in extended households do not experience these demands or benefits.     

基于市盈率、预期和供求关系的股价行为动态分析模型

针对现有股票价格模型的局限性,提出一个基于市盈率、预期及供求关系的股票价格行为动态分析模型。本模型考察市盈率、预期对股票市场供求关系的影响,探讨股票价格行为与投资者对公司未来每股收益的预期之间的关系,分析现行市盈率及动态市盈率与投资者普遍认可的合理市盈率之间的偏差对上述关系的影响,得出股票价格是在投资者对公司未来每股收益不断预期和矫正,以及对现行市盈率、动态市盈率与他们认可的合理市盈率之间偏差的不断判断和调整的基础上和由此导致的供求力量的作用下,围绕市场普遍认可的合理市盈率而上下波动的结论。     

Decomposition of the main effects and interaction term by using orthogonal polynomials in multiple non symmetrical correspondence analysis

The multiple non symmetric correspondence analysis (MNSCA) is a useful technique for analyzing a two-way contingency table. In more complex cases, the predictor variables are more than one. In this paper, the MNSCA, along with the decomposition of the Gray–Williams Tau index, in main effects and interaction term, is used to analyze a contingency table with two predictor categorical variables and an ordinal response variable. The Multiple-Tau index is a measure of association that contains both main effects and interaction term. The main effects represent the change in the response variables due to the change in the level/categories of the predictor variables, considering the effects of their addition, while the interaction effect represents the combined effect of predictor categorical variables on the ordinal response variable. Moreover, for ordinal scale variables, we propose a further decomposition in order to check the existence of power components by using Emerson's orthogonal polynomials.     

Linearity,symmetry, and equidistance in semantic differential scales for measuring images of self and images of others

ABSTRACT

Violations of linearity, symmetry, and equidistance of scale points in semantic differential scales may be due to respondents failing to figure out antonyms, to a positivity bias, or to respondents curtailing their reading the options. Multiple correspondence analysis on data provided by a randomized between-subjects experiment (split-ballot), using a web survey of 537 German residents, shows that bipolar semantic differential scales allow for linear measurement and conceal no positivity bias, and that using not suitable adjective pairs in semantic differential scales destroys symmetry.

Dynamics of Domestic Labor Across Short‐ and Long‐Distance Family Relocations

Family relocations within developed countries are argued to have gendered consequences for paid employment, with men's careers improving and women's careers deteriorating. However, little is known about their potential relationships with outcomes in other life domains, including partnered men's and women's relative shares of domestic labor. The authors addressed this gap in knowledge by theorizing and examining how within‐couple gender gaps in domestic work evolve across short‐ and long‐distance family relocations over the life course, paying attention to the over‐time dynamics before and after event occurrence. To accomplish this, they used 12 years of panel data from the Household, Income and Labour Dynamics in Australia Survey and panel regression models. The results indicated that family relocations widen the within‐couple gender gap in weekly housework hours, largely because of shifts in women's employment situation and fertility episodes that accompany residential relocations.     

略论民主社会的内部排斥问题——以迈克尔·沃尔泽的理论为视角

西方民主社会的日益多元化导致了内部排斥,它打破了民主制是最能平等尊重并维护每个公民的基本权利的政治制度的理论承诺。内部排斥的产生原因主要包括经济发展所带来的不平等以及长期形成的习惯性偏见与多元文化的差异这两个方面。在解决这一问题时,沃尔泽强调公民参与和各种地方性社群自治的重要性,而政府在提供社会福利和保护多样性的少数文化群体等问题上则负有不可推卸的责任。
