The Effect of Religiosity on Life Satisfaction in a Secularized Context: Assessing the Relevance of Believing and Belonging

The positive relationship between religiosity and life satisfaction is well-established. This relationship is, however, likely to vary across cultural contexts and different religious affiliations. Furthermore, research is needed to uncover why religion is relevant for life satisfaction. Addressing these issues, we investigate what dimensions of being religious play a role in the life satisfaction of individuals with different religious affiliations, including the understudied Muslim category, in the highly secularized Dutch context. We examine ‘believing’, which captures how religion provides meaning and a coherent worldview, and ‘belonging’, which comprises both cultural benefits of being embedded in a congregation with a shared framework of meaning and structural benefits due to more social ties. Analyses of the NEtherlands Longitudinal Lifecourse Study (n = 5312) first indicate that Muslims display significantly lower life satisfaction than the non-religious, which appears to be due to their underprivileged social position rather than intra-religious factors of believing and belonging. Second, we find that Catholics experience significant life satisfaction benefits compared to those who are not religious, and that only belonging plays a role in this association. Next to the beneficial effect of the structural aspect of belonging, which revolves around social ties, a cultural aspect of religious belonging appears to be salient, suggesting that an important life satisfaction advantage of religious communities lies in their ability to foster a sense of solidarity and commitment through a shared framework of meaning. We make several recommendations for further research based on these findings.     

Assessing the uniqueness of language: Animal grammatical abilities take center stage

Questions related to the uniqueness of language can only be addressed properly by referring to sound knowledge of the relevant cognitive abilities of nonhuman animals. A key question concerns the nature and extent of animal rule-learning abilities. I discuss two approaches used to assess these abilities. One is comparing the structures of animal vocalizations to linguistic ones, and another is addressing the grammatical rule- and pattern-learning abilities of animals through experiments using artificial grammars. Neither of these approaches has so far provided unambiguous evidence of advanced animal abilities. However, when we consider how animal vocalizations are analyzed, the types of stimuli and tasks that are used in artificial grammar learning experiments, the limited number of species examined, and the groups to which these belong, I argue that the currently available evidence is insufficient to arrive at firm conclusions concerning the limitations of animal grammatical abilities. As a consequence, the gap between human linguistic rule-learning abilities and those of nonhuman animals may be smaller and less clear than is currently assumed. This means that it is still an open question whether a difference in the rule-learning and rule abstraction abilities between animals and humans played the key role in the evolution of language.     

Debating ethical expertise

This paper explores the relevance of the debate about ethical expertise for the practice of clinical ethics. We present definitions, explain three theories of ethical expertise, and identify arguments that have been brought up to either support the concept of ethical expertise or call it into question. Finally, we discuss four theses: the debate is relevant for the practice of clinical ethics in that it (1) improves and specifies clinical ethicists' perception of their expertise; (2) contributes to improving the perception of moral competence of non-ethicists; (3) gives insight into complementary styles of argumentation of ethicists and non-ethicists; and (4) contributes to the awareness of the problem of profession-building of (clinical) ethicists.     

Kruskal's polynomial for 2×2×2 arrays and a generalization to 2×n×n arrays

A remarkable difference between the concept of rank for matrices and that for three-way arrays has to do with the occurrence of non-maximal rank. The set ofn×n matrices that have a rank less thann has zero volume. Kruskal pointed out that a 2×2×2 array has rank three or less, and that the subsets of those 2×2×2 arrays for which the rank is two or three both have positive volume. These subsets can be distinguished by the roots of a certain polynomial. The present paper generalizes Kruskal's results to 2×n×n arrays. Incidentally, it is shown that twon ×n matrices can be diagonalized simultaneously with positive probability.The author is obliged to Joe Kruskal and Henk Kiers for commenting on an earlier draft, and to Tom Wansbeek for raising stimulating questions.
