Family concepts—a social pedagogic approach to understanding family development and working with families

Drawing upon insights from family research, this article argues that in modern Western societies the reflection of individual notions of family as well as the development of concepts of a fulfilling everyday family life has turned into a recurrent challenge throughout the life course, a challenge particularly relevant during family transitions. Professionals in the field of social work with families are increasingly faced with the task of supporting such processes of reflection and development. At the same time, there is little knowledge about how these processes look like. Building upon results of a pilot study and merging recent theoretical developments in family research with the (German) tradition of social pedagogy, a conceptual framework to study family concepts theoretically and empirically is developed. The potential as well as the limitations of this research approach are discussed drawing upon a case example taken from an ongoing longitudinal study. This study aims at revealing family concept-related processes of informal learning and thus provides an understanding of family development from a social pedagogic point of view. Finally, an outline will be given of how this research could contribute to develop an intervention method standing in the tradition of social pedagogy.     

INDIVIDUAL RISK ATTITUDES: MEASUREMENT,DETERMINANTS, AND BEHAVIORAL CONSEQUENCES

This paper studies risk attitudes using a large representative survey and a complementary experiment conducted with a representative subject pool in subjects' homes. Using a question asking people about their willingness to take risks “in general”, we find that gender, age, height, and parental background have an economically significant impact on willingness to take risks. The experiment confirms the behavioral validity of this measure, using paid lottery choices. Turning to other questions about risk attitudes in specific contexts, we find similar results on the determinants of risk attitudes, and also shed light on the deeper question of stability of risk attitudes across contexts. We conduct a horse race of the ability of different measures to explain risky behaviors such as holdings stocks, occupational choice, and smoking. The question about risk taking in general generates the best all‐round predictor of risky behavior.

Work-Related Demands Emanating from Social Change and Their Relation to Trait-Like and Occasion-Specific Aspects of Subjective Well-Being

Following current macro-level social change people are increasingly confronted with new demands encompassing perceived uncertainties concerning their job and career prospects. Studies utilizing concurrent assessments showed that perceiving a high accumulation (“load”) of such demands is negatively related to individuals’ subjective well-being. Without further evidence the interpretation of the direction of these effects, however, is equivocal. Based on the concept that individuals have a rather stable trait-like level of subjective well-being from which they may vary when confronted with changes of the external ecology, the current study examined the relationship between the reported load of demands and subjective well-being assessed as general life satisfaction and average satisfaction in domains of life (i.e., family, work, finances, and leisure). We expected that a higher load of demands corresponds to a temporary decline in well-being, while at the same time differences in the stable trait-like level of well-being account for differences in the reported demand load. For the purpose of our study, we analyzed three annual waves of assessment of German adults aged between 18 and 43 years (N = 488). Utilizing a trait-state-occasion model, we separated trait-like aspects of well-being from occasion-specific deviations. Overall, our results confirmed our expectation that effects indeed run in both directions. The higher the reported load of work-related demands, the more respondents’ well-being negatively deviated from the stable trait-like level. Beyond that a higher trait-like level of well-being corresponded to a lower demand load. Both effects revealed almost equal strength and remained stable after controlling for participants’ employment status, family status, and educational attainment.     

Checking a Semiparametric Additive Risk Model

McKeague and Sasieni [A partly parametric additive risk model. Biometrika 81 (1994) 501] propose a restriction of Aalen’s additive risk model by the additional hypothesis that some of the covariates have time-independent influence on the intensity of the observed counting process. We introduce goodness-of-fit tests for this semiparametric Aalen model. The asymptotic distribution properties of the test statistics are derived by means of martingale techniques. The tests can be adjusted to detect particular alternatives. As one of the most important alternatives we consider Cox’s proportional hazards model. We present simulation studies and an application to a real data set.     

Autoregressive distributed lag models and cointegration

Summary This paper considers cointegration analysis within an autoregressive distributed lag (ADL) framework. First, different reparameterizations and interpretations are reviewed. Then we show that the estimation of a cointegrating vector from an ADL specification is equivalent to that from an error-correction (EC) model. Therefore, asymptotic normality available in the ADL model under exogeneity carries over to the EC estimator. Next, we review cointegration tests based on EC regressions. Special attention is paid to the effect of linear time trends in case of regressions without detrending. Finally, the relevance of our asymptotic results in finite samples is investigated by means of computer experiments. In particular, it turns out that the conditional EC model is superior to the unconditional one.

Unit root testing

Summary The occurrence of unit roots in economic time series has far reaching consequences for univariate as well as multivariate econometric modelling. Therefore, unit root tests are nowadays the starting point of most empirical time series studies. The oldest and most widely used test is due to Dickey and Fuller (1979). Reviewing this test and variants thereof we focus on the importance of modelling the deterministic component. In particular, we survey the growing literature on tests accounting for structural shifts. Finally, further applied aspects are addressed, for instance, how to get the size correct and obtain good power at the same time. We thank Mu-Chun Wang for producing the figures, and an anonymous referee for comments improving the presentation.
