Paired comparisons with individual differences

A model of Bradley-Terry type for paired comparisons is considered. In addition to the usual parameters, the model allows for individual parameters and corresponding parameters for the choice-alternatives. The model is applied to a set of data from a Danish investigation of the attitude of blue collar workers towards alternative social gains. The proposed model is finally compared to a model recently suggested by Schönemann and Wang.     

The problem of the additive constant and eigenvalues in metric multidimensional scaling

This paper is concerned with the additive constant problem in metric multidimensional scaling. First the influence of the additive constant on eigenvalues of a scalar product matrix is discussed. The second part of this paper is devoted to the introduction of a new formulation of the additive constant problem. A solution is given for fixed dimensionality, by maximizing a normalized index of fit with a gradient method. An experimental computation has shown that the author's solution is accurate and easy to follow.     

On the Computation of the RMSEA and CFI from the Mean-And-Variance Corrected Test Statistic with Nonnormal Data in SEM

A new type of nonnormality correction to the RMSEA has recently been developed, which has several advantages over existing corrections. In particular, the new correction adjusts the sample estimate of the RMSEA for the inflation due to nonnormality, while leaving its population value unchanged, so that established cutoff criteria can still be used to judge the degree of approximate fit. A confidence interval (CI) for the new robust RMSEA based on the mean-corrected (“Satorra-Bentler”) test statistic has also been proposed. Follow up work has provided the same type of nonnormality correction for the CFI (Brosseau-Liard & Savalei, 2014). These developments have recently been implemented in lavaan. This note has three goals: a) to show how to compute the new robust RMSEA and CFI from the mean-and-variance corrected test statistic; b) to offer a new CI for the robust RMSEA based on the mean-and-variance corrected test statistic; and c) to caution that the logic of the new nonnormality corrections to RMSEA and CFI is most appropriate for the maximum likelihood (ML) estimator, and cannot easily be generalized to the most commonly used categorical data estimators.     

The Case of a City Where 1 in 6 Residents is a Refugee: Ecological Factors and Host Community Adaptation in Successful Resettlement

The notable success of an upstate New York community in resettling refugees raises the question of whether multiple waves of resettlement over a 15-year period have resulted in greater accommodation to refugees. Structured interviews based on transactional models of acculturation were used along with archival data to explore ecological factors supporting a host community's behavioral flexibility and perseverance in response to the influx of refugees. Evidence suggests that socioeconomic climate, historical background/social norms, and the organizational structure of agencies involved in resettlement moderate successful inclusion of refugees into a host community in a bidirectional process.     

Work, family and life-course fit: Does control over work time matter?

This study moves from “work-family” to a multi-dimensional “life-course fit” construct (employees’ cognitive assessments of resources, resource deficits, and resource demands), using a combined work-family, demands-control and ecology of the life course framing. It examined (1) impacts of job and home ecological systems on fit dimensions, and (2) whether control over work time predicted and mediated life-course fit outcomes. Using cluster analysis of survey data on a sample of 917 white-collar employees from Best Buy headquarters, we identified four job ecologies (corresponding to the job demands-job control model) and five home ecologies (theorizing an analogous home demands-home control model). Job and home ecologies predicted fit dimensions in an additive, not interactive, fashion. Employees’ work-time control predicted every life-course fit dimension and partially mediated effects of job ecologies, organizational tenure, and job category.     

美军EPAS系统对我军士兵职业分类研究的启示

EPAS（Enlisted Personnel Allocation System）是美军新开发的军人选拔分配系统。该系统采用最优线性匹配程序,通过预测绩效最大化,提高应征人员岗位匹配的有效性,以满足部队兵员分配的需求。本文从美军应征人员分配标准出发,介绍了该系统的历史沿革、主要原理,并阐明了对我军士兵职业分类研究的启迪。     

Asymptotic null distribution of person fit statistics with estimated person parameter

Person fit statistics are considered for dichotomous item response models. The asymptotic null distribution is derived for statistics which are linear in the item responses, and in which the ability parameter is replaced by an estimate. This allows the asymptotically correct standardization of linear person fit statistics with estimated ability parameter. The fact that the ability parameter is estimated usually decreases the asymptotic variance.I am indebted to Herbert Hoijtink and three anonymous referees for their comments on a previous version.     

异常反应模式的识别和分类

通过对Drasgow等人的个人适合指标l2公式的再分解,发现该指标也属于残差型类的指标。特别是和Tatsuoka的广义个人适合指标ξ指标具有类似的数学结构,除符号相反外,不同之处仅是公式中加权项。其次,该研究定义了任意两个异常反应对象的类似度,在此基础上试用多维标度法对异常反应模式进行再分类。结果说明分类是有效、实用的。     

Family and Neighborhood Fit or Misfit and the Adaptation of Mexican Americans

In this study, a person-environment fit model was used to understand the independent and combined roles of family and neighborhood characteristics on the adjustment of adults and children in a sample of 750 Mexican American families. Latent class analysis was used to identify six qualitatively distinct family types and three quantitatively distinct neighborhood types using socioeconomic and cultural indicators at each level. The results showed that members of single-parent Mexican American families may be particularly at-risk, members of the lowest-income immigrant families reported fewer adaptation problems if they lived in low-income neighborhoods dominated by immigrants, members of economically successful immigrant families may be more at-risk in integrated middle class neighborhoods than in low-income neighborhoods dominated by immigrants, and members of two-parent immigrant families appear to be rather resilient in most settings despite their low socioeconomic status.     

Work-to-family conflict, positive spillover, and boundary management: a person-environment fit approach

This study adopted a person-environment fit approach to examine whether greater congruence between employees’ preferences for segmenting their work domain from their family domain (i.e., keeping work matters at work) and what their employers’ work environment allowed would be associated with lower work-to-family conflict and higher work-to-family positive spillover. Different facets of work-to-family conflict (time-based and strain-based) and positive spillover (affective and instrumental) were examined. According to latent congruence modeling of survey data from 528 management employees, congruence was negatively related to both time-based and strain-based work-to-family conflict and positively related to work-to-family instrumental positive spillover as expected. However, contrary to expectations, congruence was negatively related to work-to-family affective positive spillover. Implications for how boundary management processes may affect both positive and negative experiences of the work-family interface are discussed.
