Young Children's Projective Abilities: what can a monster see?

Abstract A series of four tasks was presented to 3‐7 year‐old children in order to investigate their understanding of the way in which an obstruction restricts a person's view of an array. The results indicated that children's ability to predict another person's line of sight and field of view develops significantly during this period. The responses of most 4‐7 year‐olds in a nonverbal hiding game were consistent with their verbal judgments about what another person could see, but 3‐year‐olds’ responses in the hiding game were much more sophisticated than could be expected from their performance on the verbal tasks. The possibility is raised that satisfactory performance in hiding games may not always depend on a child's first working out what a seeker can see.     

PCC: A Leader of Change

Abstract

From its beginnings, the Program for Cooperative Cataloging (PCC) has been an international leader of change in bibliographic and authority control and maintenance, and metadata creation and distribution. This article highlights some PCC achievements in these areas.     

Searching the Polish Medical Bibliography (Polska Bibliografia Lekarska) for trials

Background: The Polish Medical Bibliography (Polska Bibliografia Lekarska) contains 350 000 records dating from 1979. These records from the fields of medicine, nursing, dentistry, health care systems and preclinical sciences are from nearly 300 biomedical journals published in Poland. Methods: We systematically searched the Polish Medical Bibliography Part II (1996–2006) CD‐ROM (July 2006) using both English and Polish phrases for randomized trials, manually checked results and, for the trials identified in this way, sought these on medline and embase . Results: Systematic searching identified records of 680 randomized trials from all areas of health care. Nearly 40% of these were not found on either medline or embase . Conclusions: The Polish Medical Bibliography should be of interest to health care information specialists concerned with comprehensive searches for trials.     

Correspondence of document file structures to discipline structures

Online data bases might be more valuable to users if their structures more closely matched those of the disciplines represented by the data bases. To explore this concept, a structure for the field of tropical medicine was derived from the interrelationships of signs and symptoms of 37 tropical diseases. A similar structure was derived for the interrelationships of sign and symptom index terms applied to articles on these topical diseases in the MEDLINE data base. The poor correlation of the two structures led to the suggestion that rigorous indexing of articles with sign and symptom index terms or check tags would enhance the usefulness of the data base. Similar studies could be envisioned for other disciplines and data bases.     

Reading difference: picture book retellings as contexts for exploring personal meanings of race and culture

In racially and culturally homogeneous school settings, opportunities for children to interact with those who are unlike themselves are not always available. Picture book retellings provide contexts within which students are exposed to racial and cultural differences by allowing them to engage in vicarious events with people they might not otherwise encounter. In this article, the authors explore two fourth graders' aided and unaided picture book retellings. They argue that retellings are dialogic literacy events that provide children with opportunities to explore difference through social imagination and develop empathetic response to a wide range of fictional others.     

Index of mechanical efficiency in competitive and recreational long distance runners

The purpose of this investigation was to compare external work and net energy expenditure during a bout of repetitive stretch-shortening cycles between competitive and recreational long-distance runners. Participants were divided into either competitive or recreational runners based on their maximal oxygen consumption and self-reported 1600 m times. The stretch-shortening cycle involved a repetitive hopping protocol on a force plate while measuring oxygen consumption and lactate accumulation for a total of 10 min. External work and net energy expenditure were calculated for 3 min after steady state was achieved and the ratio between these variables was utilised as an index of mechanical efficiency. Lower extremity stiffness was calculated during this interval as well. Net energy expenditure was significantly lower in competitive runners (152.6 ± 33.3 kJ) in comparison to recreational runners (200.6 ± 41.4 kJ) (P = 0.02) given similar amounts of external work performed in both groups (competitive runners = 65.6 ± 20.1 kJ, recreational runners = 68.8 ± 12.1 kJ) (P = 0.67). Index of mechanical efficiency was significantly different between competitive runners (43.2 ± 9.0%) and recreational runners (34.8 ± 5.3%) (P = 0.03). No significant differences were found in lower extremity stiffness (P = 0.64). Competitive distance runners can perform similar levels of external work with lower net energy expenditure and thus a higher index of mechanical efficiency during repetitive stretch-shortening cycles in comparison to recreational runners with similar values of lower extremity stiffness. This ability could possibly be due differences in muscle–tendon length changes, muscle pre-activation, cross-bridge potentiation and short-latency reflex responses as a result of training which should be considered for future investigation.     

Occupational health nurses' perceptions of their education and training needs to meet the new public health agenda using the nominal group technique

This was a study to collect the views of Occupational Health Nurses (OHNs) working in the NHS in the West Midlands Region of the UK. It was a project to collect OHNs' perceptions about their education and training needs to meet the new public health agenda, using a focus group technique, Nominal Group Technique (NGT). There has been a series of public policy developments recently that have focused on the work/health dimension as an element of public health (Health and Safety Executive (HSE) 1998, Department of Health (DOH), 1998, National Health Service Executive (NHSE) 1998). These initiatives require the expertise and skill of occupational health professionals in the workplace to deliver care. In many organizations occupational health is not seen as a central or integral part of the organizational structure, rather a service to be used when things go dreadfully wrong. There is a clear need for management skills in this group, together with a much stronger grounding in law and the legislative framework. There is a need to take an evidence-based approach to occupational health, and to start sharing expert knowledge that can be applied to daily working in the NHS. It was identified that clarity around funding arrangements is necessary for this group of practitioners, which will be in line with all other NHS employees. Many of the participants wanted education and training opportunities, which were offered on an incremental basis, not all at specialist practitioner level.     

Tiger Mothers and Praise Junkies: Children,Praise and the Reactive Attitudes

In this article, I look at some discussions of praising children in contemporary parenting advice. In exploring what is problematic about these discussions, I turn to some philosophical work on moral praise and blame which, I argue, indicates the need for a more nuanced response to questions about the significance of praise. A further analysis of the moral aspects of praise suggests a significant dimension of the parent‐child relationship that is missing from, and obscured by, the kind of parenting advice exemplified by the discussions of praise with which I began.     

RESEARCH REPORT

The study explores teachers’ experiences of teaching a context‐based chemistry course, Salters Advanced Chemistry, as compared with teachers of a conventional course. Second, main factors that appear to influence decisions over whether or not to adopt context‐based courses are investigated. Two hundred and twenty‐two teachers’ views of a context‐based and a conventional school advanced chemistry course were obtained from a questionnaire. Responses were analysed in six dimensions: motivation, chemical knowledge and development of concepts, learning activities, assessment, challenge to teachers and students, and teacher support. Both sets of teachers agreed that the context‐based course is more motivating to study and teach, that students would be more interested in chemistry and more likely to go to university to study chemistry, that students would be better able to study independently but that it is more demanding to teach and study. The groups differed principally about concept development and teaching strategy. The context‐based teachers believed that their course gave as good a foundation for further study as a traditional course and that the spiral curriculum was advantageous. Conventional course teachers disagreed with both statements. One significant implication to emerge from the study is the crucial role played by in‐service support in influencing the impact of a curriculum innovation.
