Patients with myotonic dystrophy often have an irregular pattern of breathing at rest, implying abnormality of breathing control. No central medullary defect has been found in such patients. We postulated that irregular breathing in myotonic dystrophy due to abnormal central respiratory output would persist during slow-wave sleep. We examined the patterns of breathing whilst awake and asleep in...

The Approximate Number System (ANS) supports basic arithmetic computation in early childhood, but it is unclear whether the ANS also supports the more complex computations introduced later in formal education. 'Solving for x' in addend-unknown problems is notoriously difficult for children, who often struggle with these types of problems well into high school. Here we asked whether 4-6-year-old...

One class of parent–child interaction that has recently received attention is a mother’s engagement with her child at a mental level. The current study operationalizes this notion by asking the mothers of 354 7to 11-year-old children drawn from a larger community sample (N 1⁄4 659) to guess the responses of their children, who, in turn, were asked to attribute thoughts to their peers in distres...

Emotional competence has an important influence on development in school. We hypothesized that reading and discussing children's books with emotional content increases children's emotional competence. To examine this assumption, we developed a literature-based intervention, named READING and FEELING, and tested it on 104 second and third graders in their after-school care center. Children who a...

The light-curves of the two large amplitude variable stars, R Scuti and AC Herculis, display irregular pulsation cycles with 'periods' of 75 and 35 days, respectively. We review the evidence that the observed time-series are generated by low dimensional chaotic dynamics. In particular, a global flow reconstruction technique indicates that the minimum embedding dimensions are 4 and 3, for R Sct ...

Ten patients over 21, in whom hypnosis could be induced, volunteered to take part in this study. They were all told that their brain waves would be examined during their anaesthetic and that hypnosis would be used to explore their feelings about the operation. Thiopentone, nitrous oxide, oxygen and ether were used to anaesthetize the patients, all of whom were undergoing dental operations. Ence...

Canadian nurse and educator Beth Perry portrays inspiring stories of exemplary nursing that are based on her study of the beliefs, actions and interactions of a group of oncology nurses. Perry interweaves stories, her field notes and poetry in a way that many nurses in the UK will recognise and find familiar. She shares her own stories and is open about her feelings.

In C. elegans, an X-chromosome-wide regulatory process compensates for the difference in X-linked gene dose between males (XO) and hermaphrodites (XX) by equalizing levels of X-chromosome transcripts between the sexes. To achieve dosage compensation, a large protein complex is targeted to the X chromosomes of hermaphrodites to reduce their expression by half. This repression complex is also tar...

Purpose. Relational aggression, rumor spreading, backstabbing, and social isolation, is psychologically damaging for adolescent girls. The purpose of this study was to provide an explanation of victimization response after experiencing peer relational aggression victimization. Methods. Grounded theory techniques were used to gain an understanding of the victimization experience and the coping r...
