WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT center dot There is increasing concern about the use of those medicines in children which have not been fully studied and licensed for childhood use. Such use is not uncommon, due in large part to a lack of availability of fully licensed products and formulations that are suitable for children. center dot There is little published information on the views of the public on this important area of paediatric care. WHAT THIS STUDY ADDS center dot A survey of 1000 members of the public in Northern Ireland indicated that such use of medicines in children is not well known. center dot However, when informed about this practice, the majority believed that it would compromise safety and increase the likelihood of adverse effects. They also believed that parents/guardians should be told if their child was prescribed a medicine that had not been fully tested in children. center dot Participants in the survey indicated that they would be reluctant to involve their child in a clinical trial to help with the licensing process unless the child was suffering from a life-threatening illness. To explore awareness and views of the general public on unlicensed use of medicines in children and on the participation of children in clinical trials. Members of the public completed a questionnaire survey administered by face-to-face interview in public areas in N. Ireland. The main outcome measures were the views on unlicensed use of medicines in children and on clinical trials in children. One thousand participants (59.2% female) took part; 610 were parents. Most participants (86%) had no previous knowledge about unlicensed use of medicines in children. Being a parent did not influence this nor did being a parent of a child who suffered from a health problem (P > 0.05). Most participants (92%) felt that parents should be told about unlicensed use of medicines, with the doctor most frequently selected as the person who should inform parents. At the outset, only 1.8% of participants felt that the use of medicines in children was unsafe. However, having been informed about unlicensed use of medicines, this proportion increased dramatically (62.4%; P <0.001). Views on whether participants would enter a child of their own into a clinical trial varied according to the health status of the child (P <0.05) i.e. a child in good health (3.9%) vs a child with a life-threatening condition (41.9%). There is limited public knowledge of unlicensed use of medicines in children and a general reluctance to involve children in clinical trials unless the child to be involved has a life-threatening condition.
Balancing deceit and disguise: How to successfully fool the defender in a 1 vs. 1 situation in rugby

Suddenly changing direction requires a whole body reorientation strategy. In sporting duels such as an attacker vs. a defender in rugby, successful body orientation/reorientation strategies are essential for successful performance. The aim of this study is to examine which biomechanical factors, while taking into account biomechanical constraints, are used by an attacker in a 1 vs. 1 duel in rugby. More specifically we wanted to examine how an attacker tries to deceive the defender yet disguise his intentions by comparing effective deceptive movements (DM+), ineffective deceptive movements (DM-), and non-deceptive movements (NDM). Eight French amateur expert rugby union players were asked to perform DMs and NDMs in a real 1 vs. 1 duel. For each type of movement (DM+, DM-, NDM) different relevant orientation/reorientation parameters, medio-lateral displacement of the center of mass (COM), foot, head, upper trunk, and lower trunk yaw; and upper trunk roll were analyzed and compared. Results showed that COM displacement and lower trunk yaw were minimized during DMs while foot displacement along with head and upper trunk yaw were exaggerated during DMs (DM+ and DM-). This would suggest that the player is using exaggerated body-related information to consciously deceive the defender into thinking he will run in a given direction while minimizing other postural control parameters to disguise a sudden change in posture necessary to modify final running direction. Further analysis of the efficacy of deceptive movements showed how the disguise and deceit strategies needed to be carefully balanced to successfully fool the defender. (C) 2010 Elsevier B.V.

The present longitudinal study sought to investigate the impact of poor phonology on children’s mathematical status. From a screening sample of 256 five-year-olds, 82 children were identified as either typically achieving (TA; N = 31), having comorbid poor phonology and mathematical difficulties (PDMD; N =31), or having only poor phonology (phonological difficulty, PD; N = 20). Children were assessed on eight components of informal and formal mathematics achievement at ages 5–7 years. PD children were found to have significant impairments in some, mainly formal, components of mathematics by age 7 compared to TA children. Analysis also revealed that, by age 7, approximately half of the PD children met the criteria for PDMD, while the remainder exhibited less severe deficits in some components of formal mathematics. Children’s mathematical performance at age 5, however, did not predict which PD children were more likely to become PDMD at age 7, nor did they differ in terms of phonological awareness at age 5. However, those PD children who later became PDMD had lower scores on verbal and non-verbal tests of general ability.

This article presents the findings of a large-scale survey (n = 1049) of ethnic awareness and attitudes among three to four-year-old children in Northern Ireland. In drawing upon and applying Bourdieu’s notion of habitus, the article demonstrates how, even at this age, the children are already beginning to embody and internalize the cultural habits and dispositions of their respective ethnic groups; namely the Protestant and Catholic communities. This is illustrated in the present article in relation to the children’s attitudes towards particular national flags and awareness of specific sports associated with their respective communities. Informed by the work of Bourdieu, the article concludes by arguing for the need for greater use of quantitative methods in conjunction with in-depth qualitative and ethnographic research to help further our understanding of the influence of ethnicity in young children’s lives.
