Testing the conditional independence and monotonicity assumptions of item response theory

When item characteristic curves are nondecreasing functions of a latent variable, the conditional or local independence of item responses given the latent variable implies nonnegative conditional covariances between all monotone increasing functions of a set of item responses given any function of the remaining item responses. This general result provides a basis for testing the conditional independence assumption without first specifying a parametric form for the nondecreasing item characteristic curves. The proposed tests are simple, have known asymptotic null distributions, and possess certain optimal properties. In an example, the conditional independence hypothesis is rejected for all possible forms of monotone item characteristic curves.The author acknowledges Paul W.

Procedural Text Structure and Reader Perceptions and Performance

This research tested the relationship between text structural variables (on vs. off the causal chain, active vs. static information, and hierarchical structure) and reader perceptions, reading time, and true-false performance for procedural texts. Twenty-four college-age participants each read 3 procedural texts. As predicted, sentences that were (a) on the causal chain, (b) active, and (c) associated with task steps were read more slowly and judged to be more important (p < .05). The results were similar to those previously found with narratives, except for the hierarchical structure variable. Also as predicted, text differences were found such that as the variation in the type of information contained in the text increased, relationships with the structural variables increased.     

Variables latentes et propriétés mentales : pour une épistémologie affirmée pragmatiste et réaliste

The reliability of models with latent variables is questioned by different authors: what is the ontology of mental properties? How to integrate the complex of mental processes with latent variables? All these debates raise the question of the legitimacy of latent variables as methodological approach comparatively to new approaches such as Network analysis. By clearly posing the ontological nature of mental properties as emergent properties of mental processes, and by clearly posing a theory of pragmatist and realistic knowledge, our work seeks to show that latent variables are efficient approaches for inferring mental properties.     

Fair process revisited: Differential effects of interactional and procedural justice in the presence of social comparison information

The competing views of fairness theory ( [Folger and Cropanzano, 1998] and [Folger and Cropanzano, 2001]) and fairness heuristic theory (Van den Bos, Lind, Vermunt, & Wilke, 1997) were tested by studying the effects of interactional (IJ), procedural (PJ), and distributive justice (knowledge of others’ outcomes [OO]) upon evaluations of outcome fairness and customer satisfaction. The participants, 369 undergraduates, were randomly allocated to scenario-based experimental conditions. A 2 (IJ) × 2 (PJ) × 4 (OO) MANOVA and stepdown analyses provided evidence of “fair process” across all levels of distributive justice for outcome fairness (p<.001) and satisfaction (p<.001), but only in relation to the effects of interactional justice. No such effects were found for procedural justice. Implications for the development of justice theory are discussed.     

Accounting for sensation seeking in route choice behavior with travel time information

The purpose of this paper is to demonstrate that latent variables, with the focus on sensation seeking concepts, incorporated in new technique of route choice modeling, improve our analyzing of route choice behavior with pre-trip travel time information. The application of a hybrid discrete choice model framework integrates a latent variable model and a route choice model by combining their measurement and structural equations. The model is estimated based on data from a laboratory experiment and a field study of a simple network. The results show that certain sensation seeking domains (e.g., thrill and adventure seeking) alongside traditional variables (e.g., travel time information) enrich our understanding and provide more insight into route choice behavior. Furthermore, observed personal variables, such as gender and marital status, may serve as causal indicators to sensation seeking variables.

Social aspects of career choice from the perspective of habitus theory

The concept of habitus designates a cognitive structure that is socially embedded and can give valuable insight into the social influences on career choice. A study investigating the relationship of habitus to career choice is presented in a sample of Icelandic youth aged 19–22 (N = 476). Measures of habitus were developed on the basis of reported cultural and leisure activities. The analysis of leisure and cultural items progressed in two steps: factor analysis and cluster analysis. The clusters constitute the four different habitus groups: Pop and fashion, Sports and rock, Music, and Literature. Correspondence factor analysis showed that the habitus groups (clusters) were related to other social variables, such as gender and class; validating habitus theory. Additionally, habitus measures were strongly linked to career variables, such as occupational perception and preferred future occupation. The results support previous research in showing that habitus theory is relevant to career counseling theory and can be a basis of understanding the relationship between social structure and career choice.     

Profils d’apprenti·e·s reflétant des tensions de rôle en formation professionnelle en alternance en Suisse

Role stress among apprentices are a key element in defining the quality of dual vocational education and training. However, few studies have examined the perceptions and importance of role tensions in this particular context. Accordingly, this contribution focuses on the role stress perceived by dual apprentices through a questionnaire survey. Latent profile analyses allowed to distinguish four apprentices’ profiles in terms of perceptions of role stress, ranging from minimal to prominent role stress. Differences in socio-demographic characteristics, motivation for choosing the training, professional identification, and intention to terminate the apprenticeship contract were also identified. The study provides information on the importance of considering apprentices as a heterogeneous population in terms of role stress, but also on the different motivational and identity issues associated with the profiles. Discussing such issues would also improve the learning experience.     

Does service failure influence customer loyalty?

There is a general consensus that customer loyalty to service providers is not solely dependent upon their level of satisfaction or dissatisfaction. However, the identified antecedents of loyalty remain, at best, highly speculative. The aim of this extensive literature review is to give some understanding of the nature of customer loyalty and the antecedent effects of service dissatisfaction. The research reviewed suggests that customer loyalty is an attitudinal state, reflecting value, trust and commitment within supplier–customer relationships. Satisfaction is one of several antecedents of loyalty. A key influence on loyalty is the offer of unique value‐delivering advantages not provided by competitors. Thus firms need to develop positive value‐based exit barriers to achieve loyalty. When service failures occur, the recovery process is likely to have a greater impact on loyalty than the original service failure. The key to successful recoveries was found to be the customer's perception of ‘fairness’. Recovery programmes must get it right first time. Customers who remain dissatisfied after a complaint has been handled are more dissatisfied than if no recovery attempt had been made. Dissatisfaction and customer satiation are major causes of a customer's exit. The solution to customer satiation is dynamic value creation. Collection and monitoring of customer data is needed for success and two‐way communication is vital. Copyright © 2002 Henry Stewart Publications.     

Women’s occupational career patterns over 27 years: Relations to family of origin, life careers, and wellness

This study aimed at identifying and describing occupational career patterns (OCPs) from age 16 to 43 by applying optimal matching techniques to sequence data obtained from a sample of Swedish women. Women’s occupational trajectories were found to be diverse. Upward mobility (3 patterns) and stable careers (4 patterns) were prevalent, but there were also women characterized by downward mobility, fluctuation and being outside the labor market (1 pattern each). Women’s OCPs were related to family of origin, but more strongly to their overall life career (i.e., multiple role constellations over the life course). The study indicates that occupational mobility patterns do matter in terms of job perceptions, work attitudes, and quality of life. The results generally confirm the popular belief of the advantage of upward mobility, followed by stable occupational careers, whereas women with downward or fluctuating careers fared worst.     

The ecology of self-monitoring effects on memory of verbal productions: Does speaking to someone make a difference?

Experiments involving verbal self-monitoring show that memory for spoken words varies with types of sensory feedback: memory is better when words are spoken aloud than when they are lip-synched or covertly produced. Such effects can be explained by the Central Monitoring Theory (CMT) via a process that matches a forward model reflecting expected sensory effects of practiced forms and sensory information during speech. But CMT oversees factors of shared attention as achieved by speaker–listener gaze, and implies that sensory feedback may not affect the learning of unpracticed forms (non-words). These aspects of CMT were examined in two experiments of self-monitoring focusing on oro-sensory feedback. In Experiment 1 we show that varying feedback creates differential effects on memory for spoken words and that speaker–listener gaze alters these effects. Using non-words, Experiment 2 shows the absence of differential feedback effects. The results confirm CMT but suggest the need to refine the theory in terms of processes that mediate attention.     

Gendered Views of Ability in Parents’ Perceptions of Their Children’s Academic Competencies

The present study was designed to examine whether parents’ views of their child’s academic competencies are structured by gendered conceptions of abilities. In a longitudinal research design, a group of parents (N = 391) were asked to assess their third-grade child’s competence in mathematics and Finnish and to respond to a set of attitude statements; when the child reached the fifth grade, the parents were asked to reassess his/her competencies. It was found that the influence of the gender stereotype was partly domain-specific: The stereotype concerning Finnish organized the parental competence assessments as early as the child’s third grade and also predicted the assessments made about the child over the next two grades, whereas the stereotype concerning mathematics only predicted the assessments made as late as the fifth grade. In the Finnish competence assessments, the gender stereotype moderated the overall gender-of-the-child effect, whereas in the mathematics competence assessments, the gender-of-the-child effect was evinced only by the parent group that endorsed the gender stereotype. Culture-bound gender expectations and attitudes toward the expectations are significant, then, for parents’ assessments of their child’s competencies as early as the elementary school years.
