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.

Lab-based usability testing and location-based ethnography are time consuming and costly. We introduce diary studies as a useful design alternative for crosscultural work. The relative strengths of the methods are assessed and some lessons from our own work with diary studies are shared.

BACKGROUND Few studies document differences in patient satisfaction with physicians in the elderly (> or = 65 years) and compare it to non-elderly (<65 years) patients. METHODS A cross-sectional survey study on a convenience sample of 20,901 patients rated their recent visit to a physician through a web-based survey. Survey included validated questions based on aspects of physician care pract...

Social class standardisation has been proposed as a method for separating the effects of occupation and "social" or "lifestyle" factors in epidemiological studies, by comparing workers in a particular occupation with other workers in the same social class. The validity of this method rests upon two assumptions: (1) that social factors have the same effect in all occupational groups in the same ...
