Cerebral laterality effects in the dual processing of prose

The degree to which the concreteness of prose material presented in an auditory fashion would interact with learners' lateral preference under different right hemispheric presentation conditions was investigated with 96 normal adults. Forty-eight subjects with consistent right preference patterns and a like number of bilateral individuals were either instructed to image, given a visual-spatial interference task, or given no instructions before listening to passages which differed in abstractness. As predicted across conditions, learners recalled a significantly greater number of ideas when the passage was concrete. Importantly, the abstractness was found to interact with subjects' inferred cerebral dominance. Whereas instructions to image and visual interference had little significant effect on mixed dominant subjects, for more consistently lateralized subjects imagery instructions increased and right-hemispheric interference decreased concrete recall. The results were interpreted in terms of visual and verbal encoding concomitant with cerebral lateralization.

Whiplash shaking syndrome: retinal hemorrhages and computerized axial tomography of the brain

Three cases of whiplash shaking injury of infants are presented. All children presented with seizures and had minimal signs of external injury. Examination of the retina revealed extensive retinal hemorrhages. These were missed on initial examination and were only discovered after pupillary dilatation. The presence of these palecentered retinal hemorrhages suggested the diagnosis of child abuse and skeletal surveys and thorough social histories confirmed the diagnosis. Despite extensive retinal hemorrhages, computerized axial tomography (C.T.) scan showed minimal inter-hemispheric bleeding. In contrast to the "Battered Child Syndrome," all the findings in whiplash shaking syndrome of infants are subtle and demand an awareness, an index of suspicion and a thorough examination which may include extensive retinal examination following dilatation of the pupils. This latter examination is frequently not performed by family physicians and residents so that the syndrome may be missed. A fourth case is also discussed where shaking is admitted on initial presentation but said to be done for resuscitation. This poses an immense diagnostic dilemma to the pediatrician since in this case the child presented later with all the signs of physical abuse.

Globalizing Librarianship: A Study-Abroad Class in Russia

This article reports on a study-abroad class to St. Petersburg, Russia, for students in library and information sciences, which took place in May–June 2012. The development of this class has led to other partnership opportunities between the University of Maryland Libraries and libraries and institutions in St. Petersburg.     

Medieval Diglossia: The Diversity of the Latin Christian Encounter with Written and Spoken Arabic in the “Crusader” County of Tripoli,with a Hitherto Unpublished Arabic Note from the Principality of Antioch (MS,AOM 3, Valletta: National Library of Malta,no. 51v)

The widespread use of Arabic in the “crusader” county of Tripoli was an obstacle between the Latin Christian Franks and their indigenous subjects. The concept of diglossia – the co-existence of divergent high and low registers within a single language – is an important but under-appreciated consideration. Arabic's marked diglossia militates against simplistic generalisations that the Franks either did or did not learn Arabic. The Romance-speaking, Latin-writing conquerors of the county of Tripoli failed to learn formal written Arabic to any appreciable degree. They did, however, learn informal spoken Arabic with more success. The Franks recognised the importance and utility of Arabic, so felt obliged to employ intermediaries – usually local Christians – to speak and write on their behalf. Some Arabic vocabulary entered the Frankish lexicon, but the consciously Latinising style of clerical authors often obscured this. Most surviving written sources from the Latin East are misleading at best, and sometimes deliberately so.

Conflicting needs and interests of researchers and service providers in child sexual abuse cases

A child sexual abuse research project was designed which was dependent on referrals from local departments of social services. Significant differences in needs and goals existed between the referral sources and the research team. Modifications of project designs were necessary in the areas of subject recruitment, allocation of project resources, design and measurement, and analysis and reporting. These modifications resulted in a beneficial blend of service and research and produced a useful service in the setting of competent research.
