Brief Report: Question-Asking and Collateral Language Acquisition in Children with Autism

The literature suggests children with autism use communication primarily for requests and protests, and almost never for information-seeking. This study investigated whether teaching “Where” questions using intrinsic reinforcement procedures would produce the generalized use of the question, and whether concomitant improvements in related language structures, provided as answers to the children’s questions, would occur. In the context of a multiple baseline across participants design, data showed that the children could rapidly acquire and generalize the query, and that there were collateral improvements in the children’s use of language structures corresponding to the answers to the questions the children asked. The results are discussed in the context of teaching child initiations to improve linguistic competence in children with autism

Characteristics of Mothers Caring for Children During Episodes of Homelessness

This study provides a description of the physical, psychological, and substance use problems of adult homeless women who are and are not caring for children. We also examined differences in the characteristics of these two groups of women. Interviews were conducted with 148 homeless women from three mid-sized U.S. cities, 24.3% of whom were caring for at least one child. Our results showed that women caring for children were more likely to be sheltered and have health insurance. Homeless women caring for children and solitary homeless women were generally similar in terms of substance abuse problems. However, rates of Borderline Personality Disorder were higher among women caring for children than among solitary homeless women. Our results are somewhat consistent with previous research, with the exception of substance abuse problems and mental health problems, which were shown to be equally problematic for all women, regardless of current caregiving status

Forest humus forms as potential indicators of soil carbon storage in Mediterranean environments

The aim of this work was to investigate the potential of forest humus forms as indicators of soil C storage. To this purpose, Mediterranean forest soils in Southern and Central Italy were examined. Sites differed for elevation, climate, parent material and vegetation conditions, while summer drought was the common ecological factor. A morpho-functional criterion, based on holorganic layers thickness and A horizon properties, was used to classify humus forms, which ranged from Dysmoder to Eumull. Such variability allowed understanding of factors influencing organic matter storage. The relations between carbon stock and humus form were investigated for the topsoil layer (0–20 cm), which was supposed to contain the soil C pools most sensitive to climate change. We found that humus forms can be grouped in statistically different populations, with respect to topsoil C stocks. The use of A horizon structure was the main diagnostic criterion and represented the most effective approach to humus classification in Mediterranean conditions. It appears that humus forms have a clear potential as indicators of organic carbon status in Mediterranean forest soils

Employment functioning and disability among community residents with bipolar affective disorder: results from an Australian community survey

Objectives: To compare employment functioning and disability among people with bipolar affective disorder in comparison to adults with schizophrenia. Methods: A secondary analysis was conducted using data from the Australian National Survey of Mental Health and Wellbeing 1997-1998. Participants were aged 18-64 years with a DSM-III-R diagnosis of either bipolar affective disorder (BPD, n = 156) or schizophrenia (n = 385) and were community residents with either outpatient or short-stay inpatient status. The survey began by screening 5,710 people for psychosis, hence the sample consists mostly of bipolar disorder with psychotic features. Those with BPD were examined both in aggregation with and in contrast to people with schizophrenia on 24 independent variables covering demographic, clinical, and functioning characteristics with respect to two employment status variables and a global rating of social and occupational functioning. Results: The unadjusted and fully adjusted models revealed key functioning differences between BPD and schizophrenia. Adjusted correlates of employment functioning unique to people with BPD were: age, course of disorder, insight into positive symptoms, impairment attributed to medication, family history of schizophrenia, lifetime substance dependence, and lifetime repeated use of illicit or non-prescription drugs. Conclusions: The population-level correlates of employment functioning among people with BPD warrant special attention when providing both clinical and vocational assistance. Employment functioning in both BPD and schizophrenia is partly explained by demographic, clinical and functioning correlates, which can be independent of global assessments of social and occupational functioning
