Don’t Ever Do That! Long-term Duties in <Emphasis Type="Italic">PD</Emphasis><Subscript><Emphasis Type="Italic">e</Emphasis></Subscript><Emphasis Type="Italic">L</Emphasis>

This paper studies long-term norms concerning actions. In Meyer’s Propositional Deontic Logic (PD _e L), only immediate duties can be expressed, however, often one has duties of longer durations such as: “Never do that”, or “Do this someday”. In this paper, we will investigate how to amend PD _e L so that such long-term duties can be expressed. This leads to the interesting and suprising consequence that the long-term prohibition and obligation are not interdefinable in our semantics, while there is a duality between these two notions. As a consequence, we have provided a new analysis of the long-term obligation by introducing a new atomic proposition I (indebtedness) to represent the condition that an agent has some unfulfilled obligation.

A Longitudinal Study of Vocational Maturity and Ethnic Identity Development

This study examines longitudinally the development of vocational maturity and ethnic identity in a majority and a minority group of 641 students in the Province of Québec, Canada. Ethnic identity and four components of vocational maturity were assessed in four cohorts at three times of measurement. Results show clearly different developmental trends in both ethnic identity and in vocational maturity for majority and minority groups: The minority group showed a linear increase in ethnic identity over time, while the majority group showed a decrease starting with the second time of measurement; vocational maturity components showed a more complex pattern of changes but demonstrated that minority participants matured significantly earlier than those from the majority group. There was a positive relationship between ethnic identity and vocational maturity for both groups.     

Dynamic perception in chess

The present study examines the dynamic aspects of perceptual processes in expert chess players. This topic is approached in terms of the anticipation processes carried out by experienced players during the encoding of chess positions. The aim of the first experiment, which used a short-term comparison task, was to stress the role of anticipation, which allows expert players to focus their attention on the area of the studied position where they expect the likely standard move to occur. The second experiment used a long-term recognition task. The results showed that expert players made many false recognitions on the new positions that could be expected from the positions presented in the preliminary study phase. Taken together, the results of the two experiments highlight the anticipatory component of expert perception.     

Objective age-of-acquisition (AoA) norms for a set of 230 object names in French: Relationships with psycholinguistic variables,the English data from Morrison et al. (1997), and naming latencies

Picture naming speed is strongly influenced by the age of acquisition (AoA) of words. Most studies of AoA have relied on adults' AoA ratings. However, objective AoA has been found to be a stronger determinant of picture naming latencies. Whereas objective AoA norms for words have been collected for some language communities, no objective AoA measures for words were previously available in French. The study provides objective AoA norms for a set of 230 object names following the procedures used by Morrison, Chappell, and Ellis (1997) to collect objective AoA measures in English. The relationships between objective AoA measures, rated AoA, other variables used in psycholinguistic experiments (name agreement, image agreement, conceptual familiarity, etc.), the English data collected by Morrison et al., and naming latencies are analysed and discussed. In addition, reanalyses of data on picture naming latencies (Bonin, Chalard, Méot, & Fayol, 2002) with the use of objective AoA norms are provided. Stepwise multiple analyses show that objective AoA is a stronger determinant of (spoken and written) naming latencies than rated AoA, whereas objective word frequency is not a reliable independent determinant and does not interact reliably with AoA in any of the analyses.     

Evaluation of ICT Applications in the New Lleida Museum,Spain

ABSTRACT

This article analyzes the use of different multimedia displays (3D recreations, interactives, audiovisuals) in the Museum of Lleida (in northeast Spain) which opened its new venue in November 2007. This art and archaeological museum has actively used information and computer technology (ICT) applications in its permanent collection in order to improve communication with its public. However, after a couple of years it was realized that some applications were not properly used by visitors and most of them did not fulfill all the expectations. For this reason, the group Òliba from the Universitat Oberta de Catalunya conducted an evaluation in 2008 aiming to find the reasons for such behavior. A new methodological framework for evaluating ICT applications is proposed and its application at the Museum of Lleida is discussed. The framework focuses not only on visitor behavior, but also on technological aspects (i.e., usability, comfort, accessibility) and communication practices.     

Context-related call combinations in female Diana monkeys

Non-human primates possess species-specific repertoires of acoustically distinct call types that can be found in adults in predictable ways. Evidence for vocal flexibility is generally rare and typically restricted to acoustic variants within the main call types or sequential production of multiple calls. So far, evidence for context-specific call sequences has been mainly in relation to external disturbances, particularly predation. In this study, we investigated extensively the vocal behaviour of free-ranging and individually identified Diana monkeys in non-predatory contexts. We found that adult females produced four vocal structures alone (‘H’, ‘L’, ‘R’ and ‘A’ calls, the latter consisting of two subtypes) or combined in non-random ways (‘HA’, ‘LA’ and ‘RA’ call combinations) in relation to ongoing behaviour or external events. Specifically, the concatenation of an introductory call with the most frequently emitted and contextually neutral ‘A’ call seems to function as a contextual refiner of this potential individual identifier. Our results demonstrate that some non-human primates are able to increase the effective size of their small vocal repertoire not only by varying the acoustic structure of basic call types but also by combining them into more complex structures. We have demonstrated this phenomenon for a category of vocalisations with a purely social function and discuss the implications of these findings for evolutionary theories of primate vocal communication.     

Modesty and style in Islamic attire: Refashioning Muslim garments in a Western context

My ethnographic fieldwork conducted with female converts to Islam in France and in Quebec (Canada) shows that, for these women, being Muslim does not necessarily mean wearing clothes with ‘oriental’ designs. Rather, they are starting their own clothing companies so as to produce distinct Muslim-Western fashions that they promote through the Internet. By interpreting Islam in a context where Muslims are a minority religious group, converts construct alternative religious and social representations of Muslim identity that accord with their feminist interpretation of the Qu’ran while simultaneously incorporating the Western background within which they were socialized. In this regard, the strategies that they develop for wearing the veil and for integrating into their environment (family, workplace, etc.) make it clear that fashion, religion and politics are interacting in multiple, creative ways. In this paper, I look at how new Muslim feminist subjectivities are produced and realized through habits of dress, resulting in new representations of the body. I explore this issue by considering dress and hairstyle strategies developed by Muslim converts, in order to examine new perspectives on the place of gender in religion as it relates to particular social contexts.
