Providing Dental Current Awareness to Faculty and Residents

Providing a current awareness service to patrons has long been a concern of many health sciences librarians. Dental librarians have a unique challenge in providing current awareness to patrons as the literature has not always been available in a timely manner through traditional systems. This article will discuss the evolution of current awareness systems, the issues facing dental librarians with regard to providing dental current awareness, and how the Wilson Dental Library addressed those issues.     

The preparation of cognitively agile principals for turnaround schools: a leadership preparation programme study

The purpose of this study was to examine the ability of two educational leadership university programmes to improve the cognitive agility of their graduates. The research looked to discover whether the aspiring principals exited the programmes with an increased ability to employ cognitive agility – the ability to use the multiple thinking skills of systems thinking, reflecting, and reframing – when engaged in their professional work and solving problems. Both Masters programmes were in School Leadership, offered through the same university department and following the same core curriculum leading to Level 1 educational leadership certification. The results indicate that of the two programmes studied, the Principal Rapid Orientation and Preparation in Educational Leadership (PROPEL) programme, designed to prepare leaders for turnaround schools, produced more cognitively agile graduates than the traditional Master’s programme. The mediating variables of participants’ years of experience and budget responsibility increased the level of cognitive agility of both programme’s graduates.     

Risk factors in early child development: Is prenatal cocaine/poly-drug exposure a key variable?

In order to explore the possible confounding effects of age, race, sex, and socioeconomic status on developmental outcomes of prenatal cocaine exposure, two matched samples of preschoolers (20 children with cocaine/polydrug in utero exposure and 20 children with no prenatal drug exposure) were compared on the Stanford-Binet: 4th ed. (S-B: 4th ed.), Social Skills Rating System, Vineland Adaptive Behavior Scale—Survey Form, Preschool Language Scale: 3rd ed. (PLS: 3rd ed.), and the Child Behavior Checklist. None of the 40 children had attended or were currently enrolled in preschool programs. Both groups had scores approximately one standard deviation below the expected mean in social skills, auditory comprehension, and expressive language. Likewise, externalizing behavior difficulties were approximately one standard deviation above the mean for both groups. Results suggest in utero drug exposure had no independent impact on cognitive, social, language, and behavioral developmental outcomes when the confounding variables of age, ethnicity, gender, and SES were controlled. © 1997 John Wiley & Sons, Inc.     

Response Time Adjustment in the Stop Signal Task: Development in Children and Adolescents

Adjusting speed to maintain fast and accurate performance is critical to goal-directed behavior. This study examined development of response time adjustments in the stop signal task in 13,709 individuals aged 6–17 years (49.0% Caucasian) across four trial types: correct and incorrect go, successful (stop-inhibit), and failed (stop-respond) trials. People sped more after correct than incorrect go responses and slowed more after failed than successful stop trials. Greater slowing after stop-respond but less slowing after stop-inhibit trials was associated with better response inhibition. Response time adjustments were evident in children as young as age 6, developed throughout childhood, and plateaued by age 10. Results were consistent with the predictions of the error detection and shifting goal priority hypotheses for adjustments.

From External Regulation to Self-Regulation: Early Parenting Precursors of Young Children's Executive Functioning

In keeping with proposals emphasizing the role of early experience in infant brain development, this study investigated the prospective links between quality of parent–infant interactions and subsequent child executive functioning (EF), including working memory, impulse control, and set shifting. Maternal sensitivity, mind-mindedness and autonomy support were assessed when children were 12 to 15 months old ( N  =   80). Child EF was assessed at 18 and 26 months. All three parenting dimensions were found to relate to child EF. Autonomy support was the strongest predictor of EF at each age, independent of general cognitive ability and maternal education. These findings add to previous results on child stress-response systems in suggesting that parent–child relationships may play an important role in children's developing self-regulatory capacities.     

The nature of the phonological processing in French dyslexic children: evidence for the phonological syllable and linguistic features' role in silent reading and speech discrimination

This study investigated the status of phonological representations in French dyslexic children (DY) compared with reading level- (RL) and chronological age-matched (CA) controls. We focused on the syllable’s role and on the impact of French linguistic features. In Experiment 1, we assessed oral discrimination abilities of pairs of syllables that varied as a function of voicing, mode or place of articulation, or syllable structure. Results suggest that DY children underperform controls with a ‘speed-accuracy’ deficit. However, DY children exhibit some similar processing than those highlighted in controls. As in CA and RL controls, DY children have difficulties in processing two sounds that only differ in voicing, and preferentially process obstruent rather than fricative sounds, and more efficiently process CV than CCV syllables. In Experiment 2, we used a modified version of the Colé, Magnan, and Grainger's (Applied Psycholinguistics 20:507–532, 1999) paradigm. Results show that DY children underperform CA controls but outperform RL controls. However, as in CA and RL controls, data reveal that DY children are able to use phonological procedures influenced by initial syllable frequency. Thus, DY children process syllabically high-frequency syllables but phonemically process low-frequency syllables. They also exhibit lexical and syllable frequency effects. Consequently, results provide evidence that DY children performances can be accounted for by laborious phonological syllable-based procedures and also degraded phonological representations.     

A 3D numerical simulation of laser-induced incandescence of soot particles in coal combustion products

Laser-induced incandescence （LII） has received increasing attention as a potentially powerful technique for in-situ measuring of the volume fraction and primary size of soot particles in combustion systems. In this study, a 3D Monte Carlo simulation combined with a Mie equation was developed to analyze the influence of spectral absorption and scattering on the measured LII flux emitted by soot particles. This paper represents a first attempt to analyze soot measurement using the LII technique in coal combustion products. The combustion products of gases （CO2, N2）, soot, and fly-ash particles, present between the location of laser-excited soot and the LII flux receiver. The simulation results indicated that an almost Beer-Lambert exponential decrease in LII flux occurred with an increase in the volume fraction of soot particles, while a nearly linear decrease occurred with an increase in the volume fraction of fly-ash particles. The results also showed that scattering effects of both soot and fly-ash particles on the LII flux could be neglected. Compared with the absorption of gases, a decrease of 20% of LII flux was observed with soot particles, and a decrease of 10% with fly-ash particles.
