Chronic lung disease (CLD) is common in individuals living with perinatally acquired HIV (PA-HIV) in southern/eastern Africa. Most of the UK PA-HIV population are African. We conducted a case-note review of CLD in 3 UK PA-HIV cohorts (n = 98). Bronchiectasis or obliterative bronchiolitis occurred in 8.1% of patients and ring/tramline opacities occurred in 19.2% of patients on chest radiograph. There may be unrecognized and underdiagnosed CLD among PA-HIV in the UK.

The ecological outcomes of civic environmental stewardship are poorly understood, especially at scales larger than individual sites. In this study we characterized civic environmental stewardship programs in the Green-Duwamish watershed in King County, WA, and evaluated the extent to which stewardship outcomes were monitored. We developed a four-step process based on the Open Standards for the Practice of Conservation to structure our evaluation and to make recommendations for future monitoring of ecological outcomes of stewardship activities. Environmental stewardship, primarily in the form of restoration projects, was common throughout the lower and middle watershed. The distribution of stewardship sites was influenced by population density, political and program boundaries, and financial and technical resources. Conceptual frameworks that link conservation goals, ecological threats, management strategies, and monitoring were rare and incomplete. Collaboration among programs was an important component of stewardship in the watershed, although communication gaps were identified between geographic regions and different ecosystems. Monitoring efforts were relatively common but unevenly distributed, often unsystematic, and usually dictated by project maintenance, funding purpose, or a program’s standard practices, rather than specific ecological outcomes and goals. As a result, monitoring results were rarely and inconsistently used for management. We recommend improving stewardship monitoring by clearly linking stewardship activities to specific conservation goals and objectives, developing reasonable quantitative outcome metrics that link upland and aquatic environments, and improving coordination and learning of monitoring efforts among multiple stewardship programs and actors.

Digging animals may alter many characteristics of their environment as they disrupt and modify the ground's surface by creating foraging pits or burrows. Extensive disturbance to the soil and litter layer changes litter distribution and availability, potentially altering fuel loads. In many landscapes, including peri-urban areas, fire management to reduce fuel loads is complex and challenging. The reintroduction of previously common digging animals, many of which are now threatened, may have the added benefit of reducing fuel loads. We experimentally examined how the reintroduction of a marsupial bandicoot, quenda (Isoodon fusciventer), altered surface fuel loads in an urban bush reserve in Perth, Western Australia. Foraging activities of quenda (where they dig for subterranean food) were substantial throughout the reserve, creating a visibly patchy distribution in surface litter. Further, in open plots where quenda had access, compared to fenced plots where quenda were excluded, quenda foraging significantly reduced litter cover and litter depth. Similarly, estimated surface fuel loads were nearly halved in open plots where quenda foraged compared to fenced plots where quenda were absent (3.6 cf. 6.4 Mg/ha). Fire behavior modeling, using the estimated surface fuel loads, indicated the predicted rate of spread of fire were significantly lower for open plots where quenda foraged compared to fenced plots under both low (29.2 cf. 51.4 m/h; total fuels) and high (74.3 cf. 130.4 m/h; total fuels) fire conditions. Although many environments require fire, including the bushland where this study occurred, fire management can be a considerable challenge in many landscapes, including urban bushland reserves, which are usually small and close to human infrastructure. The reintroduction of previously common digging species may have potential value as a complimentary tool for reducing fuel loads, and potentially, fire risk.

Collaborative approaches to natural resource management are becoming increasingly common on public lands. Negotiating a shared vision for desired conditions is a fundamental task of collaboration and serves as a foundation for developing management objectives and monitoring strategies. We explore the complex socio-ecological processes involved in developing a shared vision for collaborative restoration of fire-adapted forest landscapes. To understand participant perspectives and experiences, we analyzed interviews with 86 respondents from six collaboratives in the western U.S., part of the Collaborative Forest Landscape Restoration Program established to encourage collaborative, science-based restoration on U.S. Forest Service lands. Although forest landscapes and group characteristics vary considerably, collaboratives faced common challenges to developing a shared vision for desired conditions. Three broad categories of challenges emerged: meeting multiple objectives, collaborative capacity and trust, and integrating ecological science and social values in decision-making. Collaborative groups also used common strategies to address these challenges, including some that addressed multiple challenges. These included use of issue-based recommendations, field visits, and landscape-level analysis; obtaining support from local agency leadership, engaging facilitators, and working in smaller groups (sub-groups); and science engagement. Increased understanding of the challenges to, and strategies for, developing a shared vision of desired conditions is critical if other collaboratives are to learn from these efforts.

A Web-based survey of wildland fire managers in federal agencies in the western United States explored fire science information needs and sources, why particular sources are used, and barriers to obtaining and using information. The fire managers we surveyed rely heavily on internal agency information sources (colleagues, technical experts, and resource advisors) and are more likely to face barriers in their ability to access and use relevant information (lack of time, funding, and personnel) than problems with the quality or availability of data. Information accessibility and applicability are important to managers when deciding which information sources to use. Managers frequently access research provided by US Forest Service Research and Development specialists and university scientists through various publications, the Internet, and direct communication with scientists. Understanding the types of information fire managers need, the sources they access for information, and the barriers they face in obtaining and using information may lead to improved fire science and its dissemination, as well as more effective and efficient fire management.

In 1998 the Washington State Legislature enacted the Watershed Planning Act, which encourages local governments to develop watershed plans using collaborative processes. Objectives of the statute are to address water resource and water quality issues, salmon habitat needs and to establish instream flows. This exploratory study sought to examine two aspects of how local governments are implementing the Act: challenges and benefits associated with collaborative watershed planning and the capacity of local governments to conduct collaborative watershed planning. Using documents and interview data from four cases, it was found that all planning groups experience similar challenges, although newer planning groups experienced more challenges than groups with previous planning experience. Challenges include issues surrounding the collaborative process, interagency co-ordination and trust. Local governments struggle with building capacity to plan, particularly in the areas of funding, technical expertise, incenti...

Regulatory negotiation is a process by which representatives of affected interests, along with the regulatory agency, attempt to negotiate a consensus agreement on the content of a regulation. This study represents an empirical effort to begin to identify and sort out the roles that an agency plays in a collaborative policy-making process such as regulatory negotiation. Three regulatory negotiation cases were examined to determine the perceived roles of the U.S. Environmental Protection Agency (EPA) officials and other participants, and the study suggests a number of findings. First, that EPA fulfills a number of different roles (Expert, Analyst, Stakeholder, Facilitator and Leader) in a negotiation process; second, that EPA is expected to be an active participant in the negotiations, not simply an overseer or facilitator of interests; and finally, EPA interprets its primary role much more narrowly – as that of an expert – than do other participants. Non-agency participants view EPA's primary role as a leader, which combines technical and substantive components as well as process components. Where previously and in the theoretical literature, agencies exercise leadership through statutory authority or technical expertise, this study suggests that there are additional dimensions to that leadership role. In a collaborative process such as regulatory negotiation, the agency finds itself in a realm that demands that they effectively merge the roles of expert, analyst, and stakeholder into a more complex leadership role than has been suggested in the past.

As collaborative approaches to resolving public disputes become more prevalent, agency officials are finding themselves in unfamiliar terrain. This article offers one conceptualization of agency roles in collaborative processes, drawing from the experiences of natural resource managers and enviromental regulators at the federal level. Based on an examination of 65 cases, the authorsidentify three distinct "hat" that effective agency officals wear in collaborative processes - leader, partner, and stakeholder. The objective and function of each role is assessed, along with the implications of agency facilitation. The most successful agency representatives were able to blend the three primary roles, and did not act as facilitators of the collaborative process.

States, territories, and tribes identify nonpoint source pollution as responsible for more than half of the Nation’s existing and threatened water quality impairments, making it the principal remaining cause of water quality problems across the United States. Combinations of education, technical and financial assistance, and regulatory measures are used to inform landowners about nonpoint source pollution issues, and to stimulate the use of best management practices. A mail survey of non-commercial riparian landowners investigated how they learn about best management practices, the efficacy of different educational techniques, and what motivates them to implement land management activities. Landowners experience a variety of educational techniques, and rank those that include direct personal contact as more effective than brochures, advertisements, radio, internet, or television. The most important motivations for implementing best management practices were linked with elements of a personal stewardship ethic, accountability, personal commitment, and feasibility. Nonpoint source education and social marketing campaigns should include direct interpersonal contacts, and appeal to landowner motivations of caring, responsibility, and personal commitment.

Cerveny, Lee K.; Ryan, Clare M. 2008. Agency capacity for recreation science and management: the case of the U.S. Forest Service. Gen. Tech. Rep. PNWGTR-757. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 78 p. This report examines the capacity of natural resource agencies to generate scientific knowledge and information for use by resource managers in planning and decisionmaking. This exploratory study focused on recreation in the U.S. Department of Agriculture, Forest Service. A semistructured, open-ended interview guide elicited insights from 58 managers and 28 researchers about recreation issues, information exchange, and research-management interactions. Data were coded and analyzed using Atlas.ti®, a qualitative analysis software program. Results indicate that recreation managers seek information to address user conflicts and manage diverse activities across sites and landscapes. Managers do not always turn to the research community when looking for scientific information and are uncertain about the proper channels for communication. Managers consult a variety of information sources and aggregate various types of scientific information for use in planning and management. Managers desire greater and more diverse interactions with researchers to promote knowledge exchange useful for addressing recreation problems. Barriers to interaction include organizational differences between management and research, researcher responsiveness, relevance of information to manager needs, and the lack of formal interaction opportunities. Several structural processes were suggested to facilitate opportunities for greater interaction and information exchange.

Monocyte phenotype and function were measured in whole blood sampled from a current cohort of human immunodeficiency virus (HIV)-infected individuals attending a large, metropolitan, university-affiliated hospital. There was no significant difference in the prevalence of CD16+ monocytes or the capacity of monocytes to ingest heat-killed Mycobacterium avium complex between these individuals and HIV-uninfected control subjects, regardless of viral load, current CD4+ T cell count, nadir CD4+ T cell count, or time since diagnosis of HIV infection. CD16+ monocyte prevalence was, however, elevated in patients not currently receiving antiretroviral therapy. We conclude that HIV type 1 infection in the setting of highly active antiretroviral therapy is associated with normal monocyte function and phenotype.

Stakeholder participation in collaborative watershed planning in Washington State was examined in three watershed planning unit cases in order to understand how stakeholders participate in collaborative watershed planning, the nature of plans developed, and stakeholder perceptions of plan implementation. Through document analysis and interviews, we found broad and inclusive representation of stakeholders in the planning processes, and that a majority of stakeholder comments were reflected in the final plans. Plans were of good quality and provide a strong foundation for implementation. Factors that facilitate plan implementation include the collaborative planning process itself, funding and community support, and leadership along with early and sustained involvement. Factors that hinder plan implementation include lack of adequate funding, various legal issues, and challenges in involving landowners in plan projects.

Our central paradigm for urban ecology is that cities are emergent phenomena of local-scale, dynamic interactions among socioeconomic and biophysical forces. These complex interactions give rise to a distinctive ecology and to distinctive ecological forcing functions. Separately, both the natural and the social sciences have adopted complex system theory to study emergent phenomena, but attempts to integrate the natural and social sciences to understand human-dominated systems remain reductionist—these disciplines generally study humans and ecological processes as separate phenomena. Here we argue that if the natural and social sciences remain within their separate domains, they cannot explain how human-dominated ecosystems emerge from interactions between humans and ecological processes. We propose an integrated framework to test formal hypotheses about how human-dominated ecosystems evolve from those interactions.
