The role of beliefs in goal dynamics: prolegomena to a constructive theory of intentions

In this article we strive to provide a detailed and principled analysis of the role of beliefs in goal processing—that is, the cognitive transition that leads from a mere desire to a proper intention. The resulting model of belief-based goal processing has also relevant consequences for the analysis of intentions, and constitutes the necessary core of a constructive theory of intentions, i.e. a framework that not only analyzes what an intention is, but also explains how it becomes what it is. We discuss similarities and differences between our approach and other standard accounts of intention, in particular Bratman’s planning theory. The aim here is to question and refine the conceptual foundations of many theories of intentional action: as a consequence, although our analysis is not formal in itself, it is ultimately meant to have deep consequences for formal models of intentional agency.     

Defining ‘Modern’ Malay womanhood and the coexistent messages of the veil

The gender constructions and performances of Malay women are often perceived by outside researchers as ‘shrouded under a veil’ of increasing Islamic conservatism. Urban Malay women, however, argue that women actively engage in the construction and performance of gender identities. Based on research conducted in Kuala Lumpur, Malaysia, during 2001 and 2003, this article argues that women advantageously alter, transform and utilise the constructs placed upon them by Islam, by ethnic identification and by conceptions of ‘modernity’. Often one image of ‘womanhood’ is presented and in public - an image that is socially accepted, honoured and respected - while less publicly alternative forms of ‘womanhood’ articulate individual goals and aims. Using an agent-oriented perspective, this article further includes an analysis of women's individual renegotiations of larger cultural constructs and the ways in which the tudong, or headscarf, has become a symbol by which individual women express their understanding of social position and personal freedoms in an industrialised Islamic context.     

Religion and Spirituality in Lonely Planet's India

For years, the authors of the best-selling guide to India, Lonely Planet, has shaped the perspectives of many travellers. This article considers how religion is constructed as a category and how it is made relevant to travellers. I argue that ‘religion’ comes in two versions, one pertaining to the Indian hosts and one to travellers. Religion is based on tradition, faith and historical institutions, whose members, rituals and sacred sites are of interest to travellers. Spirituality has to do with the personal development of travellers and is exclusively referred to as philosophy.     

The danger of Durkheim: Ambiguity in the theory of social effervescence

The purpose of this article is to shed light on an ambiguity in Émile Durkheim's theory of social effervescence. Durkheim's failure to distinguish two kinds of effervescence at the heart of the religious rite has left a dangerous legacy in the study of religion. If his work is read, however, in light of René Girard's theory of the violent origins of religion, his analysis of la société can retain the distinction between the effervescence of the crowd in scapegoating and the effervescence of protecting the victims of scapegoating. This thesis is tested by briefly comparing some contemporary essays on Durkheim.     

Coordinate high-frequency pattern of stimulation and calcium levels control the induction of LTP in striatal cholinergic interneurons

Current evidence appoints a central role to cholinergic interneurons in modulating striatal function. Recently, a long-term potentiation (LTP) of synaptic transmission has been reported to occur in these neurons. The relationship between the pattern of cortico/thalamostriatal fibers stimulation, the consequent changes in the intracellular calcium concentration ([Ca2+]i), and the induction of synaptic plasticity was investigated in striatal cholinergic interneurons from a rat corticostriatal slice preparation by means of combined electrophysiological intracellular recordings and microfluorometric techniques. Different protocols of stimulation were considered, varying both the frequency and the duration of the train of stimuli. High-frequency stimulation (HFS) (three trains at 100 Hz for 3 sec, 20-sec interval) induced a rise in [Ca2+]i, exceeding by fivefold the resting level, and caused a LTP of synaptic transmission. Tetanic stimulation delivered at lower frequencies (5-30 Hz) failed to induce long-term changes of synaptic efficacy. The observed elevation in [Ca2+]i during HFS was primarily mediated by L-type high-voltage activated (HVA)-Ca2+ channels, as it was fully prevented by nifedipine. Conversely, blockade of NMDA and AMPA glutamate receptor did not affect either LTP or the magnitude of the [Ca2+]i rise. Interestingly, the pharmacological analysis of the post-tetanic depolarizing postsynaptic potential (DPSP) revealed that LTP was attributable, to a large extent, to the potentiation of the GABA(A)-mediated component. In conclusion, the expression of LTP in striatal cholinergic interneurons is a selective response to a precise stimulation pattern of induction requiring a critical rise in [Ca2+]i.
