Detection of child abuse by Dutch preventive child-healthcare doctors and nurses:Has it changed?
Abstract
Objective
Child maltreatment (i.e., abuse and neglect) is a major cause of child morbidity and death. It is a principal topic in community child-healthcare services yet little is known about the actual detection of suspected cases. We examined trends in this detection, as well as the characteristics of parents and children associated with higher rates of detection.
Methods
We obtained data on suspected cases of physical maltreatment, as well as of emotional and sexual abuse, from Dutch national samples for children aged 3 ¾ , 5-6 and 8-12 years, for 1997/98 and 2002/03 (response rates 92% and 84%, respectively, about 4,000 children each), as registered by preventive child-healthcare doctors and nurses. We assessed changes in the detection of suspected cases and also assessed the association of suspicion with the background characteristics of parents and children.
Results
Rates increased slightly over this 5-years period, from .23% to .41%, due to a quadrupling of suspected emotional abuse cases (from .06% to .24%), but without statistical significance. Suspicion of maltreatment was found to be more likely among boys, older children, and children with low-educated fathers and mothers who were younger than 27 years at the child’s birth.
Conclusions
Professionals in Dutch preventive child-healthcare services detected fewer cases of child maltreatment than might be expected on the basis of prevalence rates of self-reported maltreatment. Detection of other types of child maltreatment thus still needs further improvement in order to reach the goal of better child health.

Review on the conversion of thermoacoustic power into electricity
Thermoacoustic engines convert heat energy into high amplitude acoustic waves
and subsequently into electric power. This article provides a review of the
four main methods to convert the (thermo)acoustic power into electricity.
First, loudspeakers and linear alternators are discussed in a section on
electromagnetic devices. This is followed by sections on piezoelectric
transducers, magnetohydrodynamic generators, and bidirectional turbines. Each
segment provides a literature review of the given technology for the field of
thermoacoustics, focusing on possible configurations, operating
characteristics, output performance, and analytical and numerical methods to
study the devices. This information is used as an input to discuss the
performance and feasibility of each method, and to identify challenges that
should be overcome for a more successful implementation in thermoacoustic
engines. The work is concluded by a comparison of the four technologies,
concentrating on the possible areas of application, the conversion efficiency,
maximum electrical power output and more generally the suggested focus for
future work in the field.Comment: The following article appeared in J. Acoust. Soc. Am 143(2) and the

Support for the global feasibility of the Ages and Stages Questionnaire as developmental screener
Objective: To investigate the psychometric properties of the Dutch version of the 48 months Ages and Stages Questionnaire (D_ASQ_48). Design: Prospective cohort study of a community-based sample of children born in 2002 and 2003 whose parents filled out the D_ASQ_48 and a questionnaire on school status at 60 months. The ASQ was translated into Dutch and back-translated into English by three independent translators. Setting: Well Child Centers covering 25% of the Netherlands. Participants: Parents of 1510 preterm and 562 term children born in 2002-2003 attending routine Well Child visits at age 45-50 months. Main outcome measures: Reliability, validity and mean population scores for D_ASQ_48 compared to other countries. Results: Mean population scores for the D_ASQ_48 were mostly similar to those in the USA, Norway and Korea. Exceptions (effect sizes of difference >0.5) were problem solving (USA) and fine motor (Korea). Reliability was good for the total score (Cronbach alpha 0.79) and acceptable for all domains (0.61-0.74). As expected, infants born at gestational age Conclusions: The good psychometric properties of the Dutch ASQ_48 and the small differences when compared to other countries support its usefulness in the early detection of developmental problems amongst children worldwide.
