The objective of this analysis was to examine the answering rates, internal reliability and external validity of the Family Affluence Scale (FAS) employing data from the 2002 Irish Health Behaviour in School-aged Children study HBSC; a cross-sectional survey of 8,424 Irish schoolchildren aged 10-18. Father's occupation was reported by 80.6% of the schoolchildren and 60.6% reported on mother's o...

Composite indices have been prominently used in poverty research. However, validity of these indices remains subject to debate. This paper examines the validity of a common type of composite poverty indices using data from a cross-sectional survey of 2477 households in urban and rural KwaZulu-Natal, South Africa. Multiple-group comparisons in structural equation modelling were employed for test...

Learners often allocate more study time to challenging items than to easier ones. Nevertheless, both predicted and actual memory performance are typically worse for difficult than for easier items. The resulting inverse relations between people's predictions of their memory performance (judgments of learning; JOLs) and self-paced study time (ST) are often explained by bottom-up, data-driven ST ...

Since the Second World War, the field of organizations studies has grown substantially in the number of researchers, number of publications, and amount of research produced. It has moved from being a combination of established disciplines to becoming a quasi-discipline of its own, with its own journals and professional associations. It has established a standardized set of ancestors, a stylized...

BACKGROUND In low- and middle-income countries, many women continue working later into pregnancy. In our recent study on some areas in rural China, most women stopped working already during the first trimester (≤3 months) of pregnancy. In this paper we aimed to explore whether stopping work during early pregnancy has changed over an 8 year period (between 2001-03 and 2009); we also studied whet...

Using longitudinal data on the Boston Naming Test ( Kaplan, Goodglass, & Weintraub, 1983) collected over 20 years from healthy individuals aged 30 to 94, we examined change in lexical retrieval with age, gender, education, and their interactions. We compared results between random-effects longitudinal and traditional cross-sectional models. Random-effects modeling revealed significant linear an...

To investigate the nasal carriage of some respiratory bacterial pathogens that are responsible for infections associated with person-to-person transmission, we conducted a cohort survey of pilgrims departing to Mecca for the 2012 Hajj season. In this report, we demonstrate the acquisition of Streptococcus pneumoniae nasal carriage in returning Hajj pilgrims.
