The moderating effect of substance abuse service accessibility on the relationship between child maltreatment and neighborhood alcohol availability

This study investigates how the relationship between dense concentrations of alcohol retailers and high rates of child maltreatment may be moderated by the presence of substance abuse service facilities. Using a cross-sectional design, the study utilized data from Bergen County, New Jersey on child maltreatment reports, alcohol-selling retailers, substance abuse service facilities, and the United States Census. Findings indicate child maltreatment rates were higher in neighborhoods with lower socioeconomic status and those with greater alcohol outlet density. Neighborhoods with easily accessed substance abuse service facilities had lower rates of child maltreatment. Additionally, the relationship between child maltreatment and alcohol outlet density was moderated by the presence of substance abuse service facilities. The study findings highlight the relevance of making primary prevention approaches readily available and using multi-sector collaboration to reduce child maltreatment.     

Modified S-charts for controlling process variability

To help in the detection of variance increases and decreases, three modified versions of traditional Shewhart S-charts are evaluated in terms of their average run length values. One scheme uses control limits based on equal tail chi-square distribution probabilities. The second uses control limits based on unequal tail probabilities. The third uses warning limits based on equal tail probabilities, but requires two successive points beyond the warning limit to give an out-of-control signal. They all result in better average run length values than the traditional S-chart. Also, if the only concern is the detection of variance increases, then both S-charts and warning limit charts without lower control limits are shown to have better average run length values than those of the traditional charts.     

I hardly see my baby: challenges and highlights of being a New Zealand working mother of an infant

Combining motherhood and paid work presents a significant challenge for many women. We asked 2388 working New Zealand mothers of infants about their biggest highlight and challenge since the birth of their child. Thematic analysis revealed the top three reported highlights were Enjoyment of the Child (40%), Child Development (29%) and Attributes of the Child (16%). The top three challenges included Time Management (24%), difficulties with maternal role and responsibilities (21%) and work-related challenges (18%). Using logistic regression, working was more likely to be reported as a challenge by mothers who worked longer hours, returned to work when their infants were younger, had greater household incomes, or expressed concern about negative career consequences if they stayed on leave. Working was less likely to be reported as a challenge for mothers whose infants had health or developmental problems and who ‘wanted to get out of the house’. Practical implications are explored.     

Estimation of population size and survival of sheep blowfly,Lucilia cuprina, in the field from serial recoveries of marked flies affected by weather dispersal and age-dependent trappability

Summary A model is presented for analysis of mark-recapture data of mobile insects which, unlike the Lincoln Index, does not require marked individuals to remain within the sampling area or to mix uniformly with the wild population. The model assumes a single or multiple releases of marked insects from the centre of the sampling area and that captured individuals are not returned to the population. Dispersal rates of marked insects are estimable from serial recaptures and, for catches that are either unaffected by or have been corrected for weather effects, the model also provides estimates of mortality and age-dependent trappability. Application of the model is illustrated using mark-recapture data for adults of the Australian sheep blowflyLucilia cuprina. A Biometrics Unit report detailing all source data, program code and comparisons between dispersal models is available on request from the authors.     

‘Never mind the mechanics,what about the (sexual) ethics?’ Sex,sexuality and social work education in sexual violence prevention

ABSTRACT

This paper examines the efficacy of sexual violence prevention education (SVPE) in the USA and Australasia: areas, which have some of the worst rates for sexual violence prevalence, globally. Paradoxically, they are also at the forefront of innovations in sexual violence prevention, compared to some European countries where SVPE is virtually non-existent or at the embryonic stage, such as the UK. Drawing upon the Authors’ previous research on the delivery of SVPE in New Zealand secondary schools, and literature reviews into these innovations, the authors argue that social work education is ideally placed to develop SVPE, due to the ways that some of these innovations, coalesce with social work theory, critical andragogy, and social work values. These synergies have the potential for transnational application through the ways that they can inform SVPE in those countries where it is delivered by social workers in schools, and via the ways it can enhance the social work curriculum to improve post-qualifying practice in addressing sexual violence (SV).
