Pace of Life and Enjoyment of Life

The paper addresses the paradox that people in modern societies believe themselves to be very happy and satisfied with their lives while simultaneously are subjected to increasing time pressure and pace of life. It starts with presenting evidence for time pressure covering objective and subjective indicators. Evidence for Germany is given by comparing time-budgets in 1991/92 and in 1999. Time use among full time employed in Germany and other EU-societies in the 1990s is compared to the US and Japan by means of diary-data. As regards work life, overwork and the gap between actual and preferred working hours are examined. Survey-results on the relationship between work load, time pressure, stress and health are reported.Most of these data support the conclusion that time pressure has emerged as a major social problem. Hence citizens are beginning to consider time prosperity as a dimension of their well-being beyond their consumer wealth.However, this growing pace of life does not reduce life satisfaction and happiness. Here a paradox evolves as increasing time pressure goes hand in hand with increased subjective well-being (SWB) at country level in cross-cultural comparison as well as at individual level.In the third section some answers to this paradox are explored: A first answer is offered through the modernization theory: life satisfaction and QOL are proliferating along with economic growth and living standards. This process at the same time accelerates social life. Hence, the negative effects of time pressure are counterbalanced by various yields of the modernization process resulting in a pattern of "heavy-going" satisfaction.A second explanation is the psychological approach: time pressure fulfils positive functions for mobilizing individual resources. A variation of this argument is that the multiple-choice-society offers a wide variety of attractive options resulting in people engaging in too many activities. Here, the enjoyment of life is equated with taking advantage of every opportunity.However, this paper prefers a third approach based on Simmel's explanation of the ambivalent consequences of modernity. Even where the majority of citizens report high levels of happiness and life satisfaction – which can be explained through "arousal" or "eu-stress" – the need to ease the time-burden of disadvantaged groups and to down-speed work and social life in general is essential.     

The Role of Referent and Expert Power in Mutual Help

This study explored the roles of referent power (i.e., influence based on sense of identification) and expert power (i.e., influence based on knowledge and expertise) in Schizophrenics Anonymous (SA), a mutual-help group for persons experiencing a schizophrenia-related illness. The study describes SA participants' experience of referent and expert power with SA members, SA leaders, and with mental health professionals. It also examines whether or not referent and expert power ascribed to fellow SA participants predicts the perceived helpfulness of the group. One hundred fifty-six SA participants were surveyed. Participants reported experiencing higher levels of referent power with fellow SA members and leaders than with mental health professionals. They reported higher levels of expert power for mental health professionals and SA leaders than for SA members. The respondents' ratings of their SA group's helpfulness was significantly correlated with ratings of referent and expert power. Although expert power was the best independent predictor of helpfulness, a significant interaction between referent and expert power indicated that when members reported high referent power, expert power was not related to helpfulness. These results are interpreted to suggest that there are multiple forms of social influence at work in mutual help.     

The cognitive foundations of reading and arithmetic skills in 7- to 10-year-olds

A range of possible predictors of arithmetic and reading were assessed in a large sample (N=162) of children between ages 7 years 5 months and 10 years 4 months. A confirmatory factor analysis of the predictors revealed a good fit to a model consisting of four latent variables (verbal ability, nonverbal ability, search speed, and phonological memory) and two manifest variables (digit comparison and phoneme deletion). A path analysis showed that digit comparison and verbal ability were unique predictors of variations in arithmetic skills, whereas phoneme deletion and verbal ability were unique predictors of variations in reading skills. These results confirm earlier findings that phoneme deletion ability appears to be a critical foundation for learning to read (decode). In addition, variations in the speed of accessing numerical quantity information appear to be a critical foundation for the development of arithmetic skills.     

Care of the Self and Patient Participation in Genetic Discourse: A Foucauldian Reading of the Surgeon General's “My Family Health Portrait” Program

Critics of genetic discourse are concerned that deterministic and discriminatory views of genetics are increasingly becoming adopted. These views argue that current genetic discourse becomes a source of power whereby powerful institutions harm people with so-called “bad” genes. This essay argues that current analyses of the power of genetics discourse are grounded in an improper reading that disempowers patients. Deploying Michel Foucault's concept “care of the self,” this essay claims that genetics discourse is better understood as a way that patients take on power through rhetoric rather than a force that has power over patients. Through a close reading of the “My Family Health Portrait” program, this paper argues that patients experience a process of “subjection” wherein they become agents of and objects of genetics discourse both. This alternative mode of analyzing the power of genetics discourse has implications for our collective understanding of the operations of the care of the self and the uses of genetic information that we propose.     

A factor simplicity index

We propose an index for assessing the degree of factor simplicity in the context of principal components and exploratory factor analysis. The new index, which is called Loading Simplicity, is based on the idea that the communality of each variable should be related to few components, or factors, so that the loadings in each variable are either zero or as far from zero as possible. This index does not depend on the scale of the factors, and its maximum and minimum are only related to the degree of simplicity in the loading matrix. The aim of the index is to enable the degree of simplicity in loading matrices to be compared.The author would like to thank the review team for their insights and recommendations.

Remarks on the identifiability of thurstonian paired comparison models under multiple judgment

It is well-known that the representations of the Thurstonian models for difference judgment data are not unique. It has been shown that equivalence classes can be formed to provide a more meaningful partition of the covariance structures of the Thurstonian ranking models. In this paper, we examine the equivalence relations between Thurstonian covariance structure models for paired comparison data obtained under multiple judgment and discuss their implications on the general identification constraints and methods to check for parameter identifiability in restricted models.The author is indebted to Ulf Böckenholt and Albert Maydeu-Olivares for their significant comments and suggestions which led to considerable improvement in this article.     

Model comparison of nonlinear structural equation models with fixed covariates

Recently, it has been recognized that the commonly used linear structural equation model is inadequate to deal with some complicated substantive theory. A new nonlinear structural equation model with fixed covariates is proposed in this article. A procedure, which utilizes the powerful path sampling for computing the Bayes factor, is developed for model comparison. In the implementation, the required random observations are simulated via a hybrid algorithm that combines the Gibbs sampler and the Metropolis-Hastings algorithm. It is shown that the proposed procedure is efficient and flexible; and it produces Bayesian estimates of the parameters, latent variables, and their highest posterior density intervals as by-products. Empirical performances of the proposed procedure such as sensitivity to prior inputs are illustrated by a simulation study and a real example.This research is fully supported by a grant from the Research Grant Council of the Hong Kong Special Administrative Region, China (Project No. CUHK 4346/01H).

Nonparametric IRT: Testing the bi-isotonicity of isotonic probabilistic models (ISOP)

Nonparametric tests for testing the validity of polytomous ISOP-models (unidimensional ordinal probabilistic polytomous IRT-models) are presented. Since the ISOP-model is a very general nonparametric unidimensional rating scale model the test statistics apply to a great multitude of latent trait models. A test for the comonotonicity of item sets of two or more items is suggested. Procedures for testing the comonotonicity of two item sets and for item selection are developed. The tests are based on Goodman-Kruskal's gamma index of ordinal association and are generalizations thereof. It is an essential advantage of polytomous ISOP-models within probabilistic IRT-models that the tests of validity of the model can be performed before and without the model being fitted to the data. The new test statistics have the further advantage that no prior order of items or subjects needs to be known.     

Constraint on word-learning constraints

Many researchers have agreed that word learning in young children is guided by so-called "word-learning principles." However, these principles may make it difficult to learn a substantial part of the lexicon unless they are appropriately controlled. To learn proper names, the taxonomic assumption and/or the shape bias must be overridden; to learn names for substances, withdrawal of the whole-object assumption and/or the shape bias is required; and to learn lexical hierarchies, the mutual exclusivity assumption must be suspended. In certain languages, syntax can provide useful information in this situation. For example, if a novel noun is given to an object for which the name is known in the syntactic frame "This is X," English-speaking children may assume the noun to be a proper noun, and this will help them override the taxonomic assumption. However, this information is not available to Japanese children, since the Japanese language does not have grammatical markers to flag the distinction between count nouns and mass nouns, or the distinction between proper nouns and common nouns. In this paper, I discuss how Japanese children get around this problem.
