Bayesian inversion of geoelectrical resistivity data

Summary. Enormous quantities of geoelectrical data are produced daily and often used for large scale reservoir modelling. To interpret these data requires reliable and efficient inversion methods which adequately incorporate prior information and use realistically complex modelling structures. We use models based on random coloured polygonal graphs as a powerful and flexible modelling framework for the layered composition of the Earth and we contrast our approach with earlier methods based on smooth Gaussian fields. We demonstrate how the reconstruction algorithm may be efficiently implemented through the use of multigrid Metropolis–coupled Markov chain Monte Carlo methods and illustrate the method on a set of field data.     

The distribution of a federal entitlement: The case of adoption assistance

Adoption assistance entitlements support children whose birth parents cannot care for them. The entitlements are meant to offset the extra cost to adoptive families of raising children whose early adverse experiences leave them with special needs. Unlike other Social Security Act programs, adoption assistance is not federally administered but is administered by states or localities. State-to-state variation in administration of this federal entitlement leads to unequal treatment of similar children. Moreover, although adoption assistance is an entitlement for children, payments made by many states are systematically correlated with the characteristics of adoptive families.     

The quality of land surrounding the major urban centres of Canada,the United States and Britain

Prime agricultural land is the most productive and important foodland in a nation. When disproportionate amounts of prime farmland are located near to the major metropolitan areas of a country, national productive capacity can be adversely affected by continued urbanisation. The disproportionate location of prime agricultural land adjacent to major cities is compared in Canada, the U.S. and Britain. The bias is far larger in Canada than it is in the U.S. or Britain. Investigating the more urbanised regions of these countries, the bias of prime land with urban areas is found to be still more accentuated in Canada.     

Can we protect children from abuse? A review of three cases

Abused infants at risk of further abuse are not being protected for many reasons. The ability of a variety of professionals to recognize and manage abuse when it occurs is limited. The reasons for this are briefly presented. Three cases in which young infants were reinjured, one fatally, are presented. Continuing efforts to improve all parts of the child welfare system and community response system need to be made. In this way, infants at risk will be better protected in our society.     

A dream come true – no more residential care. A corrective note

This note is about the attempt by the Australian State and Territory child care and protection systems to do without residential programmes. It traces the process of moving to this position and the historical and policy imperatives that supported this service direction. It also outlines the consequences of the absence of 24 hours-a-day 7-days-a-week residential education or treatment programmes for difficult and disturbed young people. It is both a cautionary and corrective note designed to underline the need for some specialised and highly selective residential programmes as part of any mature child care and protection system. This is something that Australia forgot.     

Heterogeneity of Individuals with a History of Child Sexual Abuse: An Examination of Children Presenting to Treatment

The current study examined children and families who presented for treatment through Project SAFE (Sexual Abuse Family Education) following childhood sexual abuse. Pretreatment assessment data were used to develop clusters of participants with significantly differing presentation of symptom outcome following abuse. Four clusters were discovered: (a) a Highly Distressed group, whose members had clinically elevated scores on all self- and parent-report measures; (b) a Problem Behaviors group, whose members had scores within the normal range for self-report measures and elevated scores on all parent-report measures; (c) a Subclinical group, whose participants had scores below the mean and below cutoff scores for all self- and parent-report measures; and (d) a Self-reported Distress group, whose members had elevated scores on self-report measures and scores below clinical cutoffs for all parent-report measures.     

Support in the Workplace: Buffering the Deleterious Effects of Work–Family Conflict on Child Welfare Workers’ Well-Being and Job Burnout

ABSTRACT

We examined the impact of work–family conflict (WFC) on worker well-being and job burnout, as well as the role of social support in the workplace as a potential buffer against the influence of WFC. Results of hierarchical multiple regression analyses in a cross-sectional sample of 361 public child welfare workers indicate that WFC was related to reduced well-being and increased job burnout, whereas supervisory support moderated the relationship between WFC and well-being. Findings from this study hold implications to workforce management practices aimed at improving worker well-being in human service and child welfare organizations. Human resource management policies designed to manage worker schedules should aim to facilitate workers’ ability to meet work and family demands through programs such as flexible work schedules and telecommuting. Recommendations for future research on WFC and worker well-being are discussed.     

The relationship between brain lateralization measured with self-reporting techniques and with dichotic listening

Hypotheses derived from brain lateralization research have had considerable influence on contemporary personal selection and training as well as upon communication and advertising testing. These applications, however, rely upon measurements the validity of which is not proven. In the present paper research on the validity of these measurements is reviewed and findings from studies aimed at throwing further light on the cross validity of selected measurements such as self-administered questionnaires, and dichotic listening are reported. The review as well as the reported findings suggests that one has to be cautious with the application of brain lateralization theories to normal individuals till more is known about the precise functioning of the alternative measurements applied. Eventually, research on cross validation of self-reporting techniques and dichotic listening with EEC-measures is suggested.
