No full textThe study aimed to evaluate the development of awakenings during preterm and term
age in 12 low-risk infants observed between 33 and 40 weeks of post-conceptional
age. Waking was been detected through the analysis of body motility. Gross
generalized body movements with prolonged startles, marked stretching and
writhing was considered as waking, whereas vigorous, forceful abrupt body
movements with high frequency tremor sometimes superimposed upon movements were
considered as corresponding to crying. Total number of awakenings in the 24 h
does not show significant changes with age, whereas the mean duration increases
significantly, which is accounted for mainly by those awakenings starting with
crying, in particular, during the day. These data suggest a developmental gap
between the ability to sustain the waking state, which already starts to increase
before term age, and the ability to maintain prolonged sleep episodes, which has
been shown to develop later. Furthermore, the developmental difference between
awakenings starting with crying and awakenings starting with wakefulness suggests
that two kinds of awakenings might be modulated by different factors
Sleep enhances strategic thinking at the expense of basic procedural skills consolidation
No full textRecent studies show that sleep facilitates the learning of complex cognitive skills. Here, we assess the effect of sleep on performance in an ecological, multi-componential task, which requires subjects to trace on a screen as many words as possible with 16 letters, some of which (“bonuses”) multiply the value of letters or words containing them. In a within-subjects design, 23 healthy adults underwent training and retest, with a retention period (approximately 8 hr) spent awake (WK, with training in the morning and retest in the afternoon) or asleep (SL, with training in the evening and retest in the morning). The main performance measure (GLOB) results from the total value of the letters used, the number of words, their length and the strategic use of bonus letters. An additional measure (WORDS, i.e., the proportion of words correctly detected over all detectable words) was also used, mainly reflecting procedural rather than strategic skills. In WK, although GLOB increased at retest, a significant improvement emerged only for WORDS, whereas in SL only GLOB was enhanced. In WK, the GLOB improvement appears to depend on the increase in the number of words detected (GLOB and WORDS improvement measures were positively associated), whereas in SL this association was not observed, indicating a shift to more complex but more rewarding strategies. Our data contribute to the understanding of everyday life learning processes by suggesting that sleep benefits memories of future relevance and promotes preferential consolidation of strategic skills when this is useful to achieve one's goal

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
