The place of cataloguing and classification in the curricula of South African universities
Bibliography: pages 361-372.The aim of this study is to determine the place of cataloguing and classification in the library and information science curricula of South African universities today, and to determine whether, in compiling the syllabus comprising bibliographic description and subject analysis, new developments and changes are being taken into consideration. With this in mind, attention has been given to the following: (a) Developments in general have been reconstructed by means of a review of the history of cataloguing and classification, from ancient to present times; (b) a review of the comprehensive development of education for librarianship overseas and in South Africa; and (c) an investigation of the present position of bibliographic description and subject analysis in the curricula of library and information science of South African universities
Sleep estimates in children: parental versus actigraphic assessments
Background: In the context of increasing awareness about the need for assessment of sleep duration in community and clinical settings, the use of questionnaire-based tools may be fraught with reporter bias. Conversely, actigraphy provides objective assessments of sleep patterns. In this study, we aimed to determine the potential discrepancies between parentally-based sleep logs and concurrent actigraphic recordings in children over a one-week period.
Methods: We studied 327 children aged 3â10 years, and included otherwise healthy, nonsnoring children from the community who were reported by their parents to be nonsnorers and had normal polysomnography, habitually-snoring children from the community who completed the same protocol, and children with primary insomnia referred to the sleep clinic for evaluation in the absence of any known psychiatric illness. Actigraphy and parental sleep log were concomitantly recorded during one week.
Results: Sleep logs displayed an average error in sleep onset after bedtime of about 30 minutes (P , 0.01) and of a few minutes before risetime in all groups. Furthermore, subjective parental reports were associated with an overestimated misperception of increased sleep duration of roughly one hour per night independent of group (P , 0.001).
Conclusion: The description of a childâs sleep by the parent appears appropriate as far as symptoms are concerned, but does not result in a correct estimate of sleep onset or duration. We advocate combined parental and actigraphic assessments in the evaluation of sleep complaints, particularly to rule out misperceptions and potentially to aid treatment. Actigraphy provides a more reliable tool than parental reports for assessing sleep in healthy children and in children with sleep problems

Sleep Assessments In Healthy School-Aged Children Using Actigraphy: Concordance with Polysomnography
Actigraphic recordings (ACT) are widely used in school children as a less intrusive and more extended approach to evaluation of sleep problems. However, critical assessment of the validity and reliability of ACT against overnight polysomnography (NPSG) are unavailable. Thus, we explored the degree of concordance between NPSG and ACT in school-aged children to delineate potential ACT boundaries when interpreting pediatric sleep. Non-dominant wrist ACT was simultaneously recorded with NPSG in 149 healthy school-aged children (4.1 to 8.8 years old, 41.7% boys and 80.4% Caucasian) recruited from the community. Analyses were limited to the Actiware (MiniMitter-64) calculated parameters originating from 1-min epoch sampling and medium sensitivity threshold value of 40; i.e., Sleep Period Time (SPT), Total Sleep Time (TST) and Wake After Sleep Onset (WASO). SPT was not significantly different between ACT and NPSG. However, ACT significantly underestimated TST by 32.2±33.4 minutes, and overestimated WASO by 26.3±34.4 minutes. The decreased precision of ACT was also evident from moderate to small concordance correlation coefficients (0.47 for TST and 0.09 for WASO). ACT in school-aged children provides reliable assessment of sleep quantity, but is relatively inaccurate during determination of sleep quality. Thus, caution is advocated in drawing definitive conclusions from ACT during evaluation of the sleep disturbed child

Sleep Hygiene and Problem Behaviors in Snoring and Non- Snoring School-Age Children
ObjectivesâThe effects of sleep-disordered breathing, sleep restriction, dyssomnias, and parasomnias on daytime behavior in children have been previously assessed. However, the potential relationship(s) between sleep hygiene and childrenâs daytime behavior remain to be explored. The primary goal of this study was to investigate the relationship between sleep hygiene and problematic behaviors in non-snoring and habitually snoring children.
MethodsâParents of 100 5- to 8-year-old children who were reported to snore âfrequentlyâ to âalmost always,â and of 71 age-, gender-, and ethnicity-matched children who were reported to never snore participated in this study. As part of a larger, ongoing study, children underwent nocturnal polysomnography and parents were asked to complete the Childrenâs Sleep Hygiene Scale (CSHS) and the Connersâ Parent Rating Scales-Revised (CPRS-R:L).
ResultsâIn the snoring group, strong negative correlations (r = â.39, p
ConclusionsâParental reports of behavioral patterns in snoring children indicate that poorer sleep hygiene is more likely to be associated with behavior problems, including hyperactivity, impulsivity, and oppositional behavior. In contrast, no significant relationships between slee
A theory-based approach to understanding condom errors and problems reported by men attending an STI clinic
The official published version can be accessed from the link below - Copyright @ 2008 Springer VerlagWe employed the informationâmotivationâbehavioral skills (IMB) model to guide an investigation of correlates for correct condom use among 278 adult (18â35 years old) male clients attending a sexually transmitted infection (STI) clinic. An anonymous questionnaire aided by a CD-recording of the questions was administered. Linear Structural Relations Program was used to conduct path analyses of the hypothesized IMB model. Parameter estimates showed that while information did not directly affect behavioral skills, it did have a direct (negative) effect on condom use errors. Motivation had a significant direct (positive) effect on behavioral skills and a significant indirect (positive) effect on condom use errors through behavioral skills. Behavioral skills had a direct (negative) effect on condom use errors. Among men attending a public STI clinic, these findings suggest brief, clinic-based, safer sex programs for men who have sex with women should incorporate activities to convey correct condom use information, instill motivation to use condoms correctly, and directly enhance menâs behavioral skills for correct use of condoms
HPV testing on self collected cervicovaginal lavage specimens as screening method for women who do not attend cervical screening: cohort study
Objective To determine whether offering self sampling of cervicovaginal material for high risk human papillomavirus (HPV) testing is an effective screening method for women who do not attend regular cervical screening programmes
