Correlates of Children's Eating Attitude Test scores among primary school children

A total of 107 Malay primary school girls (8-9 yr. old) completed a set of measurements on eating behavior (ChEAT, food neophobia scales, and dieting experience), the Rosenberg Self-Esteem Scale, body shape satisfaction, dietary intake, weight, and height. About 38% of the girls scored 20 and more on the ChEAT, and 46% of them reported dieting by reducing sugar and sweets (73%), skipping meals (67%), reducing fat foods (60%) and snacks (53%) as the most frequent methods practiced. In general, those girls with higher ChEAT scores tended to have lower self-esteem (r=.39), indicating they were more unwilling to try new foods (food neophobic) (r=.29), chose a smaller figure for desired body size (r=-.25), and were more dissatisfied with their body size (r=.31).     

Familiarity and emotional expression influence an early stage of face processing: an electrophysiological study

Recent data indicate that the familiarity and the emotional expression of faces occur at an early stage of information processing. The goal of the present study was to determine whether these two aspects interact at the structural encoding stage as reflected by the N170 component of event-related potentials in tasks requiring the subjects either to identify whether the faces were familiar or the nature of the emotional expression. The results indicate that the neural responses to level of familiarity and emotional expression were observable at this early processing stage but without interacting. In particular, faces of personal importance to the subjects differed from those of less personal importance. Because familiarity did not interact with emotional expression at behavioral and electrophysiologic levels, our results support the contention of parallel and independent processing of faces.     

Family therapy in primary health care: Skills training and outcome evaluation

Some of the theoretical tenets of family therapy such as emphasis on the activation and utilization of existing family resources and the importance it accords to context appear to have a good fit with primary health care's commitment to empowering individuals in their struggle against ill health and the circumstances in which it occurs. This paper explores the possibility of teaching a problem-solving approach to family therapy to nurses in a South African primary health care system. Training consisted of conceptual, pragmatic, and self-growth exercises, and trainees' conceptual and performance skills were compared to the skills of a group of untrained nurses.We thank Bukelwa Selema, co-trainer on the program, for her contributions to joining effectively with the nurses and enriching the experiential process. We also thank Dr. P.J. Beukes, Dr. J.H. Olivier, Dr. G.M. Louw, Matron L.C. Langley and other staff in the Soweto primary health care system for their support. In particular, we are grateful to nursing sisters Martha Nkoane and Millicent Matomela, who roleplayed clients on the videotaped training modules. We are also grateful to Edcent Williams, who was one of the videotape raters, and Mike Spruce, Ricky Snyders, Nico Cloete, Ricky Mauer, and Brenda Radebe for their inputs at various stages of designing and implementing the programme.     

Embodied spatial transformations: "body analogy" for the mental rotation of objects

The cognitive advantage of imagined spatial transformations of the human body over that of more unfamiliar objects (e.g., Shepard-Metzler [S-M] cubes) is an issue for validating motor theories of visual perception. In 6 experiments, the authors show that providing S-M cubes with body characteristics (e.g., by adding a head to S-M cubes to evoke a posture) facilitates the mapping of the cognitive coordinate system of one's body onto the abstract shape. In turn, this spatial embodiment improves object shape matching. Thanks to the increased cohesiveness of human posture in people's body schema, imagined transformations of the body operate in a less piecemeal fashion as compared with objects (S-M cubes or swing-arm desk lamps) under a similar spatial configuration, provided that the pose can be embodied. If the pose cannot be emulated (covert imitation) by the sensorimotor system, the facilitation due to motoric embodiment will also be disrupted.     

Nation building and the politics of Islamic internationalism in Guinea: toward an understanding of Muslims’ experience of globalization in Africa

This article discusses the historical role of Islam in the political evolution of Guinea in the broader context of Muslims’ experience of nation/state building and globalization in Africa. This role is examined on the premise that Islam is one of the major globalizing forces (more in the body of the paper on this idea of Islam as a globalizing force) responsible for the formation of what experts have conceptualized as Africa’s “triple heritage” or the juncture of African traditional values, Islamic influence, and the legacy of Western colonialism. The article examines Islam’s role in the creation of cultural identities, territorial polities, and complex regional and trans-continental networks of trade and scholarship in pre-colonial West Africa; the formation of fronts of resistance to European colonial conquest and occupation; and the mobilization of new nationalist forces which sparked the national liberation struggle of the 1940s and 1950s in the region. The discussion of key concepts such as nationalism, nation/state building, internationalism, and globalization exposes the limited applicability of existing theories to the African experience by highlighting the complexity of post-colonial cultural reconstruction and nation building on the continent. From this perspective, the article focuses upon the political and ideological contradictions having marked the relations of the regime of the Parti Démocratique de Guinée (PDG) under President Ahmed Sékou Touré and conservative Guinean Muslim circles in the early years of independence, due in part to Touré’s Marxist and socialist leanings of the time. Also comprehensively discussed is this regime’s subsequent ideological incorporation and diplomatic use of Islam in an effort to curb anti-PDG opposition at home and abroad and to free itself from isolation by the West. Hence, President Touré’s successful policy of “offensive diplomatique” geared primarily toward Arab and Muslim nations and organizations but also, though somewhat indirectly, toward Western powers, serves as an example of the dynamics of Islamic internationalism in Cold War global affairs. Past experiences of party-centered and state-controlled regimentation of religious organizations under Touré’s state-party regime is compared to the current trend of self-decentralization and self-internationalization of Islamic forces in light of the challenges of religious radicalism and post-Cold War politics in Africa.

ERPs associated with visual duration discriminations in prefrontal and parietal cortex

An event-related potentials (ERP) study was undertaken to examine the role of prefrontal and parietal association cortices on selective attention and short-term memory functions in a duration discrimination task. Subjects performed better when discriminating the first stimulus relative to the second and not the reverse. Two contingent negative variations (CNV) were obtained for each stimulus duration at prefrontal regions, as well as two P300s at parietal regions. The CNV(S1) component recorded during the first stimulus (S1) appeared to be involved in selective attention at bilateral sites, while the P300(S1) component in the left hemisphere may be implicated in retaining it. The CNV(S2) wave, displayed during the second stimulus (S2), at bilateral sites and the right-sided P300(S2) wave seem to be implicated in working memory. The results indicate that recorded activity at prefrontal and parietal association cortices is tightly linked to task parameters and behavioral performances.     

Science is a Gateway for Democracy

The Arab Spring of 2011 has highlighted an unprecedent fact in the region: it was the young and educated population who established the spearheading of change, and led their countries to democracy. In this paper, we try to analyze how science has been a key factor in these moves, in Tunisia as well as in Egypt, and how it can help to anchor democracy in these countries.     

A Voxel-based lesion study on facial emotion recognition after circumscribed prefrontal cortex damage

Previous studies have shown inconsistent findings regarding the contribution of the different prefrontal regions in emotion recognition. Moreover, the hemispheric lateralization hypothesis posits that the right hemisphere is dominant for processing all emotions regardless of affective valence, whereas the valence specificity hypothesis posits that the left hemisphere is specialized for processing positive emotions while the right hemisphere is specialized for negative emotions. However, recent findings suggest that the evidence for such lateralization has been less consistent. In this study, we investigated emotion recognition of fear, surprise, happiness, sadness, disgust, and anger in 30 patients with focal prefrontal cortex lesions and 30 control subjects. We also examined the impact of lesion laterality on recognition of the six basic emotions. The results showed that compared to control subjects, the frontal subgroups were impaired in recognition of three negative basic emotions of fear, sadness, and anger – regardless of the lesion laterality. Therefore, our findings did not establish that each hemisphere is specialized for processing specific emotions. Moreover, the voxel-based lesion symptom mapping analysis showed that recognition of fear, sadness, and anger draws on a partially common bilaterally distributed prefrontal network.
