The Relative Contribution of Health Status and Quality of Life Domains in Subjective Health in Old Age

To analyze the influence of different health status dimensions and quality of life (QoL) domains on older adults’ subjective health, and to assess the role that residential satisfaction plays in these relationships. A QoL survey was conducted on a representative sample of the community-dwelling older adult population in Madrid province (Spain). Logistic regression models were applied to studying: the health status dimensions associated with satisfaction with health; the relationship between satisfaction with health and other QoL domains; and, the influence of these domains on satisfaction with life. Sociodemographic and residential characteristics were included in all the models. The determinants of satisfaction with health in the first model were: mobility, usual activities, morbidity, and satisfaction with neighborhood. QoL domains associated with health were: leisure activities, neighborhood, and finances. Satisfaction with life was explained by these three domains, along with age, family and health. In sum, leisure, neighborhood, and finances showed a positive effect on satisfaction with health and with life.     

Imagining contact reduces prejudice in preschool children

We examined the effectiveness of an imagery‐based strategy designed to reduce prejudice in preschoolers in Italy. Three studies involving different target groups (disabled children, Black children) were conducted within Italian preschools. Children (4–6 years) were asked to imagine and draw meeting an outgroup member (Studies 1 and 2) or to imagine writing a letter to an outgroup member (Study 3). Results revealed that preschoolers in the experimental condition, relative to a control group, reported less intergroup bias in the form of contact intentions and resource allocation as well as greater behavioral inclusiveness; effects were mediated by improved intergroup attitudes. Our findings are important in understanding ways that promote positive intergroup relations in ways that align with the interests of young children.

Working conditions in the export industry of northern Morocco: Legal framework and situation on the ground

Companies in northern Morocco that export manufactured goods and services run on a production system characterized by high pressure, flexible use of labour, strict supervision and the challenging of certain labour rights. This article studies the conditions of work at these enterprises on the basis of the theoretical model of the “localized global economy”, drawing distinctions based on types of enterprise, industry and occupational categories. The results show how changes to the labour law in 2004, which adopted the standards contained in international conventions, have given more power to multinational enterprises.     

The Effects of Transformational Leadership on Organizational Performance through Knowledge and Innovation*

Today's information and knowledge society requires new leaders who can confront a reality based on knowledge and foster innovation to achieve improvements in organizational performance. However, organizations sometimes fail to achieve sustainable competitive advantage due to their limited understanding of the relationships between these strategic variables. To date, very little research has analysed the direct and indirect relationships between these variables. Our study seeks to fill this research gap by analysing theoretically and empirically how the leader's perceptions of different intermediate strategic variables related to knowledge (knowledge slack, absorptive capacity, tacitness, organizational learning) and innovation influence the relation between transformational leadership and organizational performance. Based on the literature, we develop a theoretical model that shows the interrelations between these variables. We then test the model using data from 408 Spanish organizations, discuss the findings and provide several implications for business practitioners.     

Finite sample performance of frequency- and time-domain tests for seasonal fractional integration

Testing the order of integration of economic and financial time series has become a conventional procedure prior to any modelling exercise. In this paper, we investigate and compare the finite sample properties of the frequency-domain tests proposed by Robinson [Efficient tests of nonstationary hypotheses, J. Amer. Statist. Assoc. 89(428) (1994), pp. 1420–1437] and the time-domain procedure proposed by Hassler, Rodrigues, and Rubia [Testing for general fractional integration in the time domain, Econometric Theory 25 (2009), pp. 1793–1828] when applied to seasonal data. The results presented are of empirical relevance as they provide some guidance regarding the finite sample properties of these tests.     

A Note on the Prior Distributions of Weibull Parameters for the Reliability Function

In Bayesian Inference it is often desirable to have a posterior density reflecting mainly the information from sample data. To achieve this purpose it is important to employ prior densities which add little information to the sample. We have in the literature many such prior densities, for example, Jeffreys (1967 Jeffreys , H. ( 1967 ). Theory of Probability , 3rd rev. ed. . London : Oxford University Press . [Google Scholar]), Lindley (1956 Lindley , D. V. ( 1956 ). On a measure of the information provided by an experiment . Ann. Mathemat. Statist. 27 : 986 – 1005 .[Crossref] , [Google Scholar]); (1961 Lindley , D. V. ( 1961 ). The use of prior probability distributions in statistical inference and decisions . In: Neyman , J. , ed. Proceedings of the Fourth Berkeley Symposium on Mathematical Statistics and Probability . Vol. 1. Berkeley : University of California Press , pp. 453 – 468 . [Google Scholar]), Hartigan (1964 Hartigan , J. ( 1964 ). Invariant priors distributions . Ann. Mathemat.

Biometrika 76 : 604 – 608 .[Crossref], [Web of Science ®] , [Google Scholar]), etc. In the present article, we compare the posterior densities of the reliability function by using Jeffreys, the maximal data information (Zellner, 1984 Zellner , A. ( 1984 ). Maximal Data Information Prior Distributions, Basic Issues in Econometrics . Chicago : University of Chicago Press . [Google Scholar]), Tibshirani's, and reference priors for the reliability function R(t) in a Weibull distribution.     

Adventure Therapy: Nondeliberative Group Work in Action

ABSTRACT

Nondeliberative group work allows group members to generate their own solutions and provides experiential opportunities to transfer learning to life outside of a therapeutic setting. Adventure therapy is explored as a tool for engaging groups in a nondeliberative manner. The theoretical underpinnings of adventure therapy are presented and contextualized within the larger framework of experiential education. Specific methods and models of adventure work are presented and considered in relationship to nondeliberative social work with groups. Two case examples are presented to illustrate the nondeliberative nature of adventure therapy.
