Accuracy and precision of the topological mapping procedure for estimating within-tree populations of bark beetles

Summary The accuracy and precision of the topological mapping procedure for estimating within-tree populations of bark beetles was investigated for a variety of different sampling conditions. Simulation techniques were used to define the mean and standard deviation of proportional errors encountered in estimation under different sampling intensities. The number of samples collected at a particular height and the vertical spacing between heights were varied. Information presented should aid in developing sampling plans for studies of bark beetle populations and will permit the reexamination and/or recovery of historical data sets on bark beetle populations.

Mutual Benefits: Developing Relational Service Approaches Within Centrelink

Abstract

The machinery of income support can have considerable influence in people's lives, creating opportunities for social work but also tensions: access to vulnerable people, but not always on their terms. This paper argues that the challenge to social work is about more than holding on to professional discretion. It considers how social workers can influence service delivery approaches to work more relationally, pursuing a more equal involvement of clients, and recognising the complex interactive context of social and community life. The authors trace the development of such an approach within the Australian Government human services delivery agency Centrelink in Logan, Queensland, and briefly consider a parallel innovation in Newcastle, New South Wales. The authors suggest that grounding a large institutional social service agency in the realities of client and community experiences has mutual benefits, creating a more humanising, cooperative space, and displacing inefficient and sometimes tragic cycles of misunderstanding, confrontation, and disconnection.     

Collegiate-Based Emergency Medical Service: Impact on Alcohol-Related Emergency Department Transports at a Small Liberal Arts College

Abstract

Objective: The authors examined the impact of a collegiate-based emergency medical service (CBEMS) on the frequency of emergency department (ED) transports. Participants: Students transported to the ED for acute alcohol intoxication during the Fall 2008 and the Fall 2009 semesters (N = 50). Methods: The frequency of students receiving transportation to a hospital ED and the reported blood alcohol content (BAC) levels during the initial operational semester of the CBEMS were compared to those values over the same time period the previous year. Results: More than twice the number of students was transported to the ED following the introduction of CBEMS. There was no change in mean BAC levels. Conclusions: CBEMS could promote a culture conducive to increased reporting behavior, which makes the campus safer. Similar BAC levels suggest that the degree of intoxication was similar for the 2 reporting periods, but students sought emergency assistance more frequently following the inception of CBEMS.     

Resolving Mobility Constraints Impeding Rural Seniors' Access to Regionalized Services

Rural and small town places in developed economies are aging. While attention has been paid to the local transportation needs of rural seniors, fewer researchers have explored their regional transportation needs. This is important given policies that have reduced and regionalized many services and supports. This article explores mobility constraints impeding rural seniors' access to regionalized services using the example of northern British Columbia. Drawing upon several qualitative studies, we explore geographical, maintenance, organizational, communication, human resources, infrastructure, and financial constraints that affect seniors' regional mobility. Our findings indicate that greater coordination across multiple government agencies and jurisdictions is needed and more supportive policies and resources must be in place to facilitate a comprehensive regional transportation strategy. In addition to discussing the complexities of these geographies, the article identifies innovative solutions that have been deployed in northern British Columbia to support an aging population. This research provides a foundation for developing a comprehensive understanding of the key issues that need to be addressed to inform strategic investments in infrastructure and programs that support the regional mobility and, hence, healthy aging of rural seniors.     

A Model of Comparative Ethics Education for Social Workers

ABSTRACT

Social work ethics education models have not effectively engaged social workers in practice in formal ethical reasoning processes, potentially allowing personal bias to affect ethical decisions.¹ Using two of the primary ethical models from medicine, a new social work ethics model for education and practical application is proposed. The strengths and weaknesses of specific extant social work and medical models are reviewed and addressed by the new model and its educational process. The development, components, and use of the social work model are detailed, and an education process example is provided.     

Collateral Damage on the Home Front: The Gulf in America

>Combat casualties in the Persian Gulf War among Coalition troops were by all estimates miraculously low. However, the fallout of the war for many groups on the home front may have been more pernicious in the long term than expected or estimated. This paper sketches some of the consequences of the Persian Gulf War for racial and ethnic minorities in the military, the less tangible and visible affects on the young, and the exacerbation of tensions in terms of social distress between the government and the media in the coverage of the campaign in Kuwait.     

Comparing the Effects of Amount of Conflict on Children's Adjustment Following Parental Divorce

This study examined the immediate and short-term effects on children of the conflict (as reflected by the level of court involvement) their family experiences during divorce proceedings. Families going through various levels of divorce (dissolution, divorce with little litigation, moderate litigation, and high levels of litigation) were investigated. Seventy-six parents (31 men and 45 women) between the ages of 22 and 53 who had children ranging in age from 2 to 17 years old participated. The Divorce Adjustment Inventory–Revised was completed by the parents immediately following the divorce hearing and again 6 months later. Results indicated that families experiencing a higher level of conflict (as measured by level of court involvement) displayed more family conflict or maladjustment, less favorable divorce conditions and child coping ability, and less positive divorce resolution. Implications of the study and indications for future research are discussed.     

Modeling the Impact of the Affordable Care Act and the Individual Mandate on Californians

The Patient Protection and Affordable Care Act (ACA) was designed to provide health insurance to uninsured or underinsured individuals. We used the California Simulation of Insurance Markets (CalSIM) model to predict the experience of consumers in California, who will be faced with new insurance options through Medicaid, employer-sponsored insurance, and the individual market in 2014 and beyond. We explored the response and characteristics of Californians who will and will not secure insurance coverage, with and without the “individual mandate” or minimum coverage requirement (MCR). We found 1.8 million Californians (38 %) of the 4.7 million eligible uninsured will secure coverage by 2019 with the MCR, while only 839,000 (18 % of the eligible uninsured) would obtain coverage without it.     

A Meta-Analysis of Culturally Sensitive Interventions Designed to Reduce High-Risk Behaviors Among African American Youth

ABSTRACT

This study sought to determine the effectiveness of culturally sensitive interventions (CSIs) in reducing high risk behaviors with African American youth. A meta-analysis was conducted to assess the effectiveness of CSIs across seven studies. African American youth who participated in CSIs were less likely to engage in high risk behaviors compared to those who did not participate. The effect size was moderate (g = .35). Although the findings should be considered tentative, the results provide an initial quantitative assessment of CSI effectiveness that future evaluations and meta-analyses can build upon as CSI research expands.
