Nest boxes are routinely installed as a substitute for natural tree hollows to provide den and nest sites for a range of hollow-utilising fauna. We installed 120 nest boxes in 20 patches of indigenous vegetation (remnants) across the urban/suburban landscape of Melbourne, south-eastern Australia, and investigated their use by indigenous and exotic vertebrate species over a period of 12 months. Nest-box use was dominated by the common brushtail possum (Trichosurus vulpecula), the common ringtail possum (Pseudocheirus peregrinus) and the common myna (Acridotheres tristis), an aggressive introduced bird. We found that brushtail and ringtail possums utilised nest boxes all year round but more frequently in cooler months (May–August). Common mynas dominated nest-box use during spring/summer, potentially reducing the availability of this resource to indigenous species. We found evidence that the probability of a nest box being occupied by either species of possum was greater in remnants with abundant possum populations. Brushtail possums preferred thick-walled pine nest boxes over thin-walled plywood nest boxes, most likely owing to differences in their thermal insulation properties. Although considerable economic costs would be involved in using nest boxes as a long-term substitute for hollow-bearing trees, nest boxes may provide a temporary hollow resource until hollow-bearing trees are recruited in urban remnants.

The United States lacks a cohesive strategy to deter Russian aggression. Despite being militarily and economically inferior, Russia has undermined the United States and its allies by exploiting the "gray zone," or the conceptual space between war and peace where nations compete to advance their national interests. In dealing with Russia, the United States must shift its strategic framework from a predominantly military-centric model to one that comprises a whole-of-government approach. The holistic approach must leverage a combination of diplomacy, information, military, and economic (DIME) measures. In this timely and prescient monograph, three active duty military officers and national security fellows from the Harvard Kennedy School look to address this contemporary and complex problem. Through extensive research and consultation with some of the nation's and academia's foremost experts, the authors offer policymakers a menu of strategic options to deter Russia in the gray zone and protect vital U.S. national security interests. ; https://press.armywarcollege.edu/monographs/1378/thumbnail.jpg

In 1991, approximately 21 000 student athletes were actively participating in organized athletics in Hawaii's 61 (38 public and 23 private) secondary schools. Of the 61 schools, only 5 (all private) employed full-time, NATABOC-certified athletic trainers (ATCs) to facilitate the sports health care of their respective student athletes. In an attempt to convince the state legislature that providing funding to hire ATCs was a primary health and safety issue in the state, a community-based educational platform was established and a twofold needs-assessment study was implemented statewide. The educational platform was aimed at parents, coaches, athletic directors, and school administrators. The needs-assessment studies consisted of a 30-question survey on the current practices of sports health care and a year-long injury surveillance survey within the 38 public secondary schools. There were significant differences between the public and private schools with respect to the practice of sports health care. The public school student athletes demonstrated a normative incidence of injury rate. These findings definitively quantified and qualified the need to hire ATCs in the public secondary schools. In July of 1993, the State of Hawaii funded a 2-year athletic training pilot program for approximately $1.2 million, following an extensive lobbying effort and media campaign.

Purpose: A strong interpersonal relationship after stroke is important for the prevention of depression in survivors and family caregivers. This study aimed to test the feasibility of quality of relationship intervention for stroke dyads called Hand in Hand (HiH). Methods: Sixteen dyads were randomized into either the HiH group ( n = 8) or information, support, and referral (ISR) control group ( n = 8). HiH dyads received up to eight sessions, with topics prioritized according to a 17-item screening tool. ISR dyads received up to eight sessions that included information, active listening, and referrals. Feasibility, acceptability, and outcomes data were collected for both groups. Results: The HiH and ISR groups were feasible and acceptable. Caregivers in both groups, as well as survivors in the ISR group, experienced improvements in depressive symptoms and other select outcomes. Conclusions: Findings suggest that HiH is feasible to implement with stroke dyads and that it merits further refinement and testing.

Purpose: (1) To compare demographic, mental health, service usage, and emotional and behavioral characteristics and strengths of youth receiving care from depressed versus nondepressed caregivers and (2) to determine whether a community-based program for reducing problematic behaviors and bolstering strengths is equally effective for youth with depressed versus nondepressed caregivers. Methods: Data from 165 caregiver–youth dyads were analyzed using Pearson's χ2 tests, unpaired t-tests, and paired t-tests to determine pretreatment differences between groups and differences in youth outcomes over time. Results: Results indicated that youth with depressed caregivers accessed different services, exhibited more problematic behaviors, and possessed fewer strengths. However, youth with depressed caregivers also showed significantly more improvement over time than did youth with nondepressed caregivers. Discussion: Findings suggest that additional outreach to depressed caregivers about available services is needed. Additionally, caregiver depression may not always have as negative of an impact on youth outcomes as previously thought.

Despite progress on this front, fire ecology is restricted by a dissonance between two dominant paradigms: 'fire mosaics' and 'functional types'. The fire mosaic paradigm focuses on animal responses to fire events and spatial variation, whereas the functional type paradigm focuses on plant responses to recurrent fires and temporal variation. Fire management for biodiversity conservation requires input from each paradigm because animals and plants are interdependent and influenced by spatial and temporal dimensions of fire regimes. We propose that better integration of animal-based and plant-based approaches can be achieved by identifying common metrics that describe changes in multiple taxa; linking multiple components of the fire regime with animal and plant data; understanding plant-animal interactions; and incorporating spatial and temporal characteristics of fires into conservation management. Our vision for a more integrated fire ecology could be implemented via a collaborative and global network of research and monitoring sites, where measures of animals and plants are linked to real-time data on fire regimes. ; Kelly was funded by the Australian Research Council Centre of Excellence for Environmental Decisions and a Victorian Postdoctoral Research Fellowship delivered by veski on behalf of the Victorian Government.

[Extract] It's make or break time for Australia's national parks. National parks on land and in the ocean are dying a death of a thousand cuts, in the form of bullets, hooks, hotels, logging concessions and grazing licences. It's been an extraordinary last few months, with various governments in eastern states proposing new uses for these critically important areas.

There are meager prospective data from nonclinical samples on the link between anxiety disorders and suicide or the extent to which the association varies over time. We examined these issues in a cohort of 309,861 United States Air Force service members, with 227 suicides over follow-up. Mental disorder diagnoses including anxiety, mood, and substance use disorders (SUD) were based on treatment encounters. Risk for suicide associated with anxiety disorders were lower compared to mood disorders and similar to SUD. Moreover, the associations between mood and anxiety disorders with suicide were greatest within a year of treatment presentation.
