Priming vs. rhyming : orthographic and phonological representations in the left and right hemispheres

The right cerebral hemisphere has long been argued to lack phonological processing capacity. Recently, however, a sex difference in the cortical representation of phonology has been proposed, suggesting discrete left hemisphere lateralization in males and more distributed, bilateral representation of function in females. To evaluate this hypothesis and shed light on sex differences in the phonological processing capabilities of the left and right hemispheres, we conducted two experiments. Experiment 1 assessed phonological activation implicitly (masked homophone priming), testing 52 (M = 25, F = 27; mean age 19.23 years, SD 1.64 years) strongly right-handed participants. Experiment 2 subsequently assessed the explicit recruitment of phonology (rhyme judgement), testing 50 (M = 25, F = 25; mean age 19.67 years, SD 2.05 years) strongly right-handed participants. In both experiments the orthographic overlap between stimulus pairs was strictly controlled using DICE [Brew, C., & McKelvie, D. (1996). Word-pair extraction for lexicography. In K. Oflazer & H. Somers (Eds.), Proceedings of the second international conference on new methods in language processing (pp. 45–55). Ankara: VCH], such that pairs shared (a) high orthographic and phonological similarity (e.g., not–KNOT); (b) high orthographic and low phonological similarity (e.g., pint–HINT); (c) low orthographic and high phonological similarity (e.g., use–EWES); or (d) low orthographic and low phonological similarity (e.g., kind–DONE). As anticipated, high orthographic similarity facilitated both left and right hemisphere performance, whereas the left hemisphere showed greater facility when phonological similarity was high. This difference in hemispheric processing of phonological representations was especially pronounced in males, whereas female performance was far less sensitive to visual field of presentation across both implicit and explicit phonological tasks. As such, the findings offer behavioural evidence indicating that though both hemispheres are capable of orthographic analysis, phonological processing is discretely lateralised to the left hemisphere in males, but available in both the left and right hemisphere in females.

Global governance in the collective interest : between complex multilateralism and networked governance

This paper navigates the theoretical landscape between the concepts of Robert O’Brien et al’s ‘Complex Multilateralism’ and Anne-Marie Slaughter’s ‘Networked Governance’ to make both an empirical and normative argument about the practices of Global Governance. By incorporating state and non-state actors, as well as overlapping international regimes and institutions in the practices of Global Governance, this paper argues that the transition from traditional multilateralism, based almost solely on the activity of states, towards varying degrees of complex multilateralism is both clearly evident and gathering pace. A stronger form of complex multilateralism would appear to be heading towards what Slaughter describes as ‘Networked Governance’ that would see a rejection of a centralized approach to global governance. The paper takes this concept into consideration and maps out how this may, or may not, be an effective approach to Global Governance.

Gaining representations of children's and adults' constructions of sustainability issues

In this decade of Education for Sustainable Development, it is timely to consider the methodological issues associated with researching this topic not only with adults but also with the young children who, as members of the next generation, will experience the success or otherwise of current environmental sustainability efforts. We argue that it is important when making methodological choices to recognize that both the sustainability issues themselves and the way individuals learn about these issues, are socially and culturally constructed. In this article we are interested in ways of gaining representations of individuals' mental constructions of environmental sustainability issues. We recount experiences from two projects, one which used the approach of analyzing children's drawings to gain representations of how children in Mexico understand environmental issues and the other which employed adult participant-directed photography as the principal data collection method conducted mainly in the north of South Africa.

Wikipedia model for collective intelligence : a review of information quality

Online information seekers increasingly utilise the online encyclopaedia Wikipedia as a key reference source. Wikipedia's special feature is that it is based on the collective intelligence (CI) of lay citizens. Its consensus-building participatory knowledge-building processes replace traditional encyclopaedia processes founded on the knowledge of experts and gatekeeping practices. However there have been reports of concerns with the level of information quality provided by Wikipedia articles. This paper explores information quality for Wikipedia theoretically. First, it conceptualises the Wikipedia model of knowledge production and second, it analyses information quality for the model. Finally, the paper recommends some improvements for the model and discusses other implications for knowledge management theory and practice.

Images of embodied old age in contemporary Japan

Since the late 1980s, representations of Japanese national identity and Japanese old age have been deconstructed. Images of the resilience of traditional cultural and social institutions are shown to have over-emphasized social and cultural homogeneity, elided social differentiation and inequality and minimized the significance of historical transformation. Key institutions of the postwar modernization project, including the patriarchal seniority system and household structure, are being transformed through globalization and feminization. This thesis focuses on the problem of representing individual and collective ageing in Japan in the context of modernization. Research is focussed on the contradictions, within essentialist representations of Japanese collective and individual identity, between socially constructed policy forms of old age and collective identities. Contemporary trends towards individualization and diversification of identities, and discourses on the ageing/information society, indicate cultural distance between an instrumentally rational administration and the life world of old people. Research explores the concept of embodiment through its significance in debates on postmodernization of the lifecourse in accordance with the structural shifts towards a postindustrial structure. This study examines representations of old age in broader social and cultural processes. Images of the social and cultural trajectory of the lifecourse draw attention to the embodiment of individual identities and ultimately generational cultures in contemporary social and cultural spaces. This research is the result of analyses of old age, which have been informed by postmodern theory. It in turn informs sociological theorizations of cultural representations of old age in contemporary societies.

Young children’s understanding of photo self-representations

This experiment examined delayed self-recognition in 24 2.5-year-old and 24 3-year-old children. Children were marked covertly with a sticker on their forehead while playing a game, after which their photograph was taken. When show this photograph, the 3- but not the 2.5-year-olds reached to remove this sticker reliably. However, the older children reached reliably only when first shown how a recently taken photograph can be used to guide their search for an object in the testing room that was not directly visible to the unaided eye. Implications of the findings in terms of the development of a temporally extended sense of self are discussed.

Building the perfect beast : scientific romance and Jewish representations 1880-1914

Various cultural mediums portrayed Jews in Britain in the late Victorian and Edwardian periods. Scientific romance harnessed past communicative 'discourses' such as history, folklore, theology, and mythology and was an innovative form of literature that heralded a new era in the construction of Jewish identity between 1880 to 1914.

Examining representations of women's leadership in the media and Australian universities

Examines how diverse academic women educational leaders experienced and negotiated media representations of leadership in their work. The thesis argues that feminist leadership analyses assume a commonality of women's interests, ignoring the diversity, which exists between different groups of women and the material impact of diversity upon female leaders' work.

Illness representations and cancer screening in older women

This research investigated why some older women do not obtain screening mammograms and Pap smear tests. In-depth interviews found many beliefs which are contrary to screening and influenced the women's screening behaviour.
