Bivariate deconvolution with SIMEX: an application to mapping Alaska earthquake density

Constructing spatial density maps of seismic events, such as earthquake hypocentres, is complicated by the fact that events are not located precisely. In this paper, we present a method for estimating density maps from event locations that are measured with error. The estimator is based on the simulation–extrapolation method of estimation and is appropriate for location errors that are either homoscedastic or heteroscedastic. A simulation study shows that the estimator outperforms the standard estimator of density that ignores location errors in the data, even when location errors are spatially dependent. We apply our method to construct an estimated density map of earthquake hypocenters using data from the Alaska earthquake catalogue.     

Document Delivery as a Supplement or Replacement for Serial Subscriptions

Abstract

Increasing serials costs and shrinking budgets present challenges for academic libraries to continue providing sufficient access to scholarly articles. Rapid document delivery services can serve as an effective means to fill the gap caused by serials cancellations. This column examines several of the existing document delivery service providers and addresses issues involved in their implementation.     

Pathways to adoption for minority ethnic children in England – reasons for entry to care

There have been concerns about the over‐representation of minority ethnic children in care in England for many years. This paper reports on the reasons why a sample of 120 minority ethnic children with adoption recommendations entered care. The study found no evidence that children were being removed unfairly or in a discriminatory way. However, there were significant differences by ethnic group in the characteristics of children and their mothers, in reasons for entry and in age at referral. These differences needed to be better understood, and interventions targeted at improving the circumstances and stresses within families that lead to abuse, neglect or relinquishment are also needed. Simply focusing on reducing the number of minority ethnic children in care will not in itself produce better outcomes for children.     

Health and community services for trafficked women: an exploratory study of policy and practice

The trafficking of women has attracted considerable international and national policy attention, particularly since the UN Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children (2000), of which the Australian Government has been a signatory since 2005. The provision of health and community services for trafficked women is a central feature of this Protocol, but in Australia service provision is made difficult by how trafficked women are understood and treated in policy and legal terms. This study aimed to explore the provision of health and community services for trafficked women in the Greater Sydney region through a series of interviews with government and non‐government organisations. The findings reveal that services have been inaccessible as a result of sparse, uncoordinated, and poorly funded provision. The major obstacle to adequate and appropriate service provision has been a national policy approach focusing on ‘border protection’ and criminalisation rather than on trafficked women and their human rights. We conclude that further policy development needs to focus on the practical implications of how such rights can be translated into the delivery of health and community services that trafficked women can access and be supported by more effectively.     

The Impact of Elder Abuse Education on Young Adults

The present study examined the effectiveness of educational interventions in altering tolerance for and behavioral intentions of elder abuse among college student young adults. Participants were 225 undergraduates who were assigned to one of four educational groups: Elder Abuse Education, Aging Education, Family Education, and a Pre- and Posttest only condition. While the Elder Abuse Education group reported less tolerance and intentions for elder abuse compared to the other groups at the immediate posttest, a decrement in such positive changes at 1-month follow-up was observed in such persons. These mixed findings suggest that while specific interventions may reduce elder abuse tolerance, supplemental educational efforts over time may be necessary to maintain intervention-specific gains in intentions and behaviors particular to elder abuse.     

Tracing Stigma in Long-Term Care Insurance in Israel: Stakeholders’ Views of Policy Implementation

A rapidly expanding number of baby boomers provide care to aging parents. This study examines associations between caregiver status and outcomes related to awareness and anticipation of future long-term care (LTC) needs using 2007 Connecticut Long-Term Care Needs Assessment survey data. Baby boomers who were adult child caregivers (n = 353) versus baby boomers who were not (n = 1242) were more likely to anticipate some future LTC needs and to have considered certain financing strategies. Although baby boomer adult child caregivers more readily anticipate some future LTC needs, they are not taking specific actions. It is important to address the need for public education directed toward those who are currently (or have recently completed) caring for aging parents.     

Family Transitions and Children’s Well-Being During Adolescence

This study used longitudinal prospective data from a representative Canada-wide survey to assess the impact of childhood family experience on well-being during adolescence. First, we constructed family composition profiles to capture the number and type of changes in family structure that occurred in our sample over a 12-year period. Then, we examined links between initial family status, family composition profiles, timing of parental separation, and later behavioral outcomes during adolescence. Marital status at birth, as well as 2 different family transition profiles, were linked to externalized problems during adolescence. Timing of the first family transition suppressed the effect of family transition profiles on adolescent behavioral outcomes.     

Longitudinal Evaluation of a Teenage Pregnancy Case Management Program in Oklahoma

The purpose of this study was to evaluate the efficacy of a school-based case management intervention in reducing teen-pregnancy. A nonrandomized intervention/comparison schools mixed-method evaluation design was employed. Participants included 203 pregnant and parenting teens with annual follow-up over a 3-year period. The results indicated that the time to repeat pregnancy was delayed among pregnant teens, high school drop-out rates were reduced among parenting teens, and pregnant teens were less likely to deliver before 36 weeks in the intervention versus the comparison school. Case management at a school setting is a promising approach to decrease repeat teen pregnancy.
