Heritage, health and place:The legacies of local community-based heritage conservation on social wellbeing
Geographies of health challenge researchers to attend to the positive effects of occupying, creating and using all kinds of spaces, including 'green space' and more recently 'blue space'. Attention to the spaces of community-based heritage conservation has largely gone unexplored within the health geography literature. This paper examines the personal motivations and impacts associated with people's growing interest in local heritage groups. It draws on questionnaires and interviews from a recent study with such groups and a conceptual mapping of their routes and flows. The findings reveal a rich array of positive benefits on the participants' social wellbeing with/in the community. These include personal enrichment, social learning, satisfaction from sharing the heritage products with others, and less anxiety about the present. These positive effects were tempered by needing to face and overcome challenging effects associated with running the projects thus opening up an extension to health-enabling spaces debates
Living Shoreline Design Guidelines for Shore Protection in Virginia’s Estuarine Environments
Living Shoreline Design Guidelines for Shore Protection in Virginia’s Estuarine Environment
The Chesapeake Bay has about 6.5 million people living in its coastal counties and much of the shoreline is privately-owned. For communities along the shore, the continual shore retreat may be a problem. When land along the shore show signs of erosion, property owners tend to address it.
These guidelines are meant to address the need to educate consultants, contractors, and other professionals in the use of living shoreline strategies. It provides the necessary information to determine where they are appropriate and what is involved in their design and construction. The guidelines focus on the use of created marsh fringes but also touch on the use of oysters and beaches for shore protection. The guidelines were created for the Virginia portion of the Chesapeake Bay estuarine system but may be applicable to other similar estuarine environments. These references and tools are for guidance only and should not replace professional judgments made at specific sites by qualified individuals
Detection of multiple nitroaromatic explosives via formation of a Janowsky complex and SERS
Military-grade explosives such as 2,4,6-trinitroluene (TNT) are still a major worldwide concern in terms of terror threat and environmental impact. The most common methods currently employed for the detection of explosives involve colorimetric tests, which are known to be rapid and portable; however, they often display false positives and lack sensitivity. Other methods used include ion mobility mass spectrometry, gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS), which despite producing more reliable results often require large, expensive instrumentation and specially trained staff. Here we demonstrate an alternative approach that utilizes the formation of a colored Janowsky complex with nitroaromatic explosives through reaction of the enolate ion of 3-mercapto-2-butanone. The colored complex is formed rapidly and can then be detected sensitively using surface-enhanced Raman scattering (SERS). We demonstrate that SERS can be used as a quick, sensitive, and selective technique for the detection of 2,4,6-trinitrotoluene (TNT), hexanitrostillbene (HNS), and 2,4,6-trinitrophenylmethylnitramine (tetryl) with a detection limit of 6.81 ng mL -1 achieved for TNT, 17.2 ng mL -1 for tetryl, and 135.1 ng mL -1 for HNS. This method of detection also requires minimal sample preparation, can be done in a solution-based format, and utilizes the same precursor reagents for complex formation with each of the explosives which can then be identified due to the specificity of the unique SERS response obtained. We demonstrate the ability to simultaneously identify three explosive compounds within a total analysis time of 10 min. This method of detection shows promise for the development of rapid and portable SERS-based assays which can be utilized in the field in order to achieve reliable and quantitative detection
Living Shoreline Design Guidelines for Shore Protection in Virginia’s Estuarine Environments
The Chesapeake Bay has about 10 million people living along its shores (Chesapeake Bay Foundation, 2017) and about 150,000 new people move into the Bay watershed each year. For communities along the shore, the continual shore retreat may be a problem. When land along the shore shows signs of erosion, property owners tend to address it.
In the past, shore stabilization strategies generally were stone revetments or wood bulkheads. Though these strategies are effective at shore stabilization, they can create a disconnect between the upland and the water and typically provide few natural habitats along the shoreline. In the past 30 years, a more natural approach to shore stabilization, termed “living shorelines,” has used marshes, beaches, and dunes effectively to protect the shoreline along Virginia’s creeks, rivers, and bays. Numerous benefits result from this approach to shoreline management including creating critical habitat for marine plants and animals, improved water quality, and reduced sedimentation. In addition, most waterfront property owners enjoy a continuous connection to the water that allows for enhanced recreational opportunities. However, a recent analysis has shown that between 2011 and 2016 only 24% of the permits granted for shore protection were considered living shorelines (ASMFC, 2016).
Since 2006, when the Virginia Department of Environmental Quality’s Coastal Zone Management Program held a Living Shoreline Summit, the use of this shore management strategy has been actively promoted. Providing educational programs for consultants and contractors who work in this field to ensure that they are familiar and comfortable with living shoreline strategies was one way to achieve this. As a result, funding was provided in 2010 and again in 2016 to develop living shoreline design guidance for shore protection and a contractor’s training course. In an effort to grow the number of contractors, local staff, and non-profit organizations who are familiar with correct living shoreline project design, the guidance and course have been updated.
These guidelines are meant to address the need to educate consultants, contractors, and other professionals in the use of living shoreline strategies. It provides the necessary information to determine where they are appropriate and what is involved in their design and construction. The guidelines focus on the use of created marsh fringes but also touch on the use of beaches for shore protection. The guidelines were created for the Virginia portion of the Chesapeake Bay estuarine system (Figure 1-1) but may be applicable to other similar estuarine environments.

Integrated programs for women with substance use issues and their children: a qualitative meta-synthesis of processes and outcomes
Integrated programs for mothers with substance abuse issues: A systematic review of studies reporting on parenting outcomes
<p>Abstract</p> <p>Background</p> <p>Integrated treatment programs (those that include on-site pregnancy-, parenting-, or child-related services with addiction services) were developed to break the intergenerational cycle of addiction, dysfunctional parenting, and poor outcomes for mothers and children, yet there has been no systematic review of studies of parenting outcomes.</p> <p>Objectives</p> <p>As part of larger systematic review to examine the effectiveness of integrated programs for mothers with substance abuse issues, we performed a systematic review of studies published from 1990 to 2011 with data on parenting outcomes.</p> <p>Methods</p> <p>Literature search strategies included online bibliographic database searches, checking printed sources, and requests to researchers. Studies were included if all participants were mothers with substance abuse problems at baseline, the treatment program included at least one specific substance use treatment and at least one parenting or child service, and there were quantitative data on parenting outcomes. We summarized data on parenting skills and capacity outcomes.</p> <p>Results</p> <p>There were 24 cohort studies, 3 quasi-experimental studies, and 4 randomized trials. In the three randomized trials comparing integrated programs to addiction treatment-as-usual (<it>N </it>= 419), most improvements in parenting skills favored integrated programs and most effect sizes indicated that this advantage was small, <it>d</it>s = -0.02 to 0.94. Results for child protection services involvement did not differ by group. In the three studies that examined factors associated with treatment effects, parenting improvements were associated with attachment-based parenting interventions, children residing in the treatment facility, and improvements in maternal mental health.</p> <p>Conclusions</p> <p>This is the first systematic review of studies evaluating the effectiveness of integrated programs on parenting. The limited available evidence supports integrated programs, as findings suggest that they are associated with improvements in parenting skills. However, more research is required comparing integrated programs to addiction treatment-as-usual. This review highlights the need for improved methodology, study quality, and reporting to improve our understanding of how best to meet the parenting needs of women with substance abuse issues.</p
