The development of the comprehensive child maltreatment scale

In this paper, data are presented from four studies that describe and evaluate the psychometric properties of the Comprehensive Child Maltreatment Scale (CCMS). This is a new measure that assesses five separate types of maltreatment experienced during childhood (sexual abuse, physical abuse, psychological maltreatment, neglect and witnessing family violence) and the existence of multi-type maltreatment. This scale is the only paper-and-pencil research scale available that assesses all five types of child maltreatment separately. In Studies 1 and 2, the CCMS for Adults was used to assess retrospective reports of adults' own childhood experiences (N=313). The parallel version of the CCMS for Parents was used in Studies 3 and 4 to assess parent reports of the experiences of children from 5 to 12 years of age (N=100). Adequate test-retest reliability and internal consistency were found for each of the scales of the CCMS for Adults and the CCMS for Parents. As well as performing an exploratory factor analysis, a criterion validity check on the CCMS for Adults revealed high correlations with appropriate subscales from the Child Abuse Trauma Scale. These preliminary data on the CCMS for Adults and Parents show that they are psychometrically sound and useful research tools in the study of multiple forms of child abuse and neglect. The CCMS for Adults and the CCMS for Parents allow for a simple yet comprehensive assessment of multi-type maltreatment.

Use of an auditory looming task to test infants' sensitivity to sound pressure level as an auditory distance cue

This study describes how an auditory looming technique was used to investigate 4-to 6-month-old infants' sensitivity to sound pressure level (SPL) as an auditory distance cue. Thirty-two infants were tested in complete darkness and presented with auditory stimuli that underwent unidirectional variations in SPL (40–70dB). The rate at which SPL was varied during the course of trials (past vs. slow) was manipulated by varying trial length (5s vs. 10s).

A sound barrier

A sound barrier made from recycled concrete aggregate, the sound barrier being divided into at least two or more sections, each said section including: an inner layer for supporting the barrier, and an outer layer, said outer layer having a predetermined number of voids for absorbing sound energy at a particular frequency, wherein said respective outer layers of said at least two or more sections have different predetermined numbers of voids so as to absorb sound energy at different frequencies.

Shaking hands on the fringe : negotiating the Aboriginal world at King George's Sound

In 1826 the British set up a garrison on the edges of an Aboriginal world at King George’s Sound, the site of present day Albany, Western Australia, with the aim of deterring the French from occupying the area.

The British newcomers and the area’s Indigenous inhabitants, the King Ya-nup, came to share a small space, forcing both cultures to adapt in order to communicate and interact with one another. Within this sphere associations and friendships were formed that were as surprising as they were unique.

This ethnographic history narrates several intimate cross-cultural stories of the developing relationships between British and Aboriginal individuals at King George’s Sound. The episodes recounted go beyond the common ‘friendly’ or ‘violent’ encounters, unearthing instead how and why particular King Ya-nup engaged with the British world, utilising the new presence to seeming advantage.

Shaking Hands on the Fringe presents innovative history writing and beautifully crafted prose in the tradition of Greg Dening and other writers of ethnographic history.

Despite the limited scope of the subject, the first two points liberate this book into a national (and international) interest: it is not a local book.

Monaural sound localization : mechanisms and processes

A review of the literature established that localization acuity measured during monaural listening conditions was directly related to various methodological considerations. These included method of attenuation, segment of auditory space where monaural localization was measured, and the presence or absence of head movements. An extensive measurement of monaural localization was made with due consideration of these factors, allowing a more comprehensive evaluation of monaural acuity and the underlying processes that were involved. Establishing a monaural condition is dependent both on the attenuation level of the occluded ear and the signal level, both of which are clearly inter-related since the attenuation level of the occluded ear sets the maximum level of die stimulus. In a series of experiments it was established that there was a minimum signal level for accurate localization. Testing on both sides of the head revealed that there were three regions of monaural localization acuity. The first was about the interaural axis on the ipsilateral ear where monaural localization was relatively accurate, the second a region either side of the MSP where there was some loss of localization, and a third about the interaural axis on the ipsilateral side where virtually no monaural localization ability existed. In the final series of experiments it was established that head-movements allowed subjects to extend the accuracy of the first region by minimizing the distance between the sound and the ipsilateral interaural axis, thus compensating for the loss of localization ability in the second and third regions. This was determined from changes recorded in the error data, and also the extent and direction of measured head-movements. The results of this series of experiments demonstrated the relationship between spectral cues and monaural localization. Firstly, monaural localization was not possible in the absence of accurate spectral information. Thus large errors were observed in the third region where there was blockage of the high-frequencies by the head, and in all regions during the presentation of low signal levels where the high-frequencies fell below threshold. Secondly, the inaccuracy of the second region due to the loss of information from the second pinna suggested that there was a binaural component with relation to pinna cues. It seems that for sounds in this region the spectral modifications from both pinnae are processed to determine a sound's location in space.
