Deployment of phytoremediation at the 317/319 area at Argonne National Laboratory - East
The 317 and 319 Areas are located on the extreme southern end of the ANL-E site, immediately adjacent to the DuPage County Waterfall Glen Forest Preserve. The 317 Area is an active hazardous and radioactive waste processing and storage area. In the late 1950s, liquid waste was placed in the unit known as the French Drain. Since that time, this waste has migrated into underlying soil and groundwater. The principal environmental concern in the 317 Area is the presence of several VOCs in the soil and groundwater and low levels of tritium in the groundwater beneath and down gradient of the site. The 319 Area Landfill and French Drain are located immediately adjacent to the 317 Area. The principal environmental concern in the 319 Area is the presence of radioactive materials in the waste mound, in the leachate in the mound, and in the shallow groundwater immediately down gradient of the landfill. Several interim actions have already been implemented in this area, to reduce the VOC and tritium releases from these areas, as the result of the Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) conducted from December 1994 through September 1996

Freihoelser Forst Local Training Area Demonstration Project: Prescription development and installation
The Freiholser Forst Local Training Area (LTA) Rehabilitation Demonstration Project is part of the Integrated Training Area Management program being developed by the US Army Corps of Engineers` Construction Engineering Research Laboratory for the Seventh Army Training Command of the US Army in Europe. The rehabilitation demonstration project was begun in 1987 to develop and demonstrate rapid, cost-effective methods to stabilize the LTA`s barren, eroding maneuver areas and make training conditions more realistic. The sandy, infertile, and acidic soils at the LTA are considered the major factor limiting rehabilitation efforts there. The project involves the evaluation of three procedures to revegetate the soils, each incorporating identical methods for preparing the seedbed and a single seed mixture consisting of adapted, native species but using different soil amendments. All three treatments have satisfactorily reestablished vegetation and controlled erosion on the demonstration plots at the LTA, but their costs have varied widely

Giving the benefit of the doubt
Faced with evidence that what is person said is false, we can nevertheless trust
them and so believe what they say Ăł choosing to give them the benefit of the
doubt. This is particularly notable when the person is a friend, or someone we are
close to. Towards such persons, we demonstrate a remarkable epistemic partiality.
We can trust, and so believe, our friends even when the balance of the evidence
suggests that what they tell us is false. And insofar as belief is possible, it is also
possible to acquire testimonial knowledge on those occasions when the friends
know what they tell us. This paper seeks to explain these psychological and
epistemological possibilities
Training in childhood obesity management in the United States: a survey of pediatric, internal medicine-pediatrics and family medicine residency program directors
<p>Abstract</p> <p>Background</p> <p>Information about the availability and effectiveness of childhood obesity training during residency is limited.</p> <p>Methods</p> <p>We surveyed residency program directors from pediatric, internal medicine-pediatrics (IM-Peds), and family medicine residency programs between September 2007 and January 2008 about childhood obesity training offered in their programs.</p> <p>Results</p> <p>The response rate was 42.2% (299/709) and ranged by specialty from 40.1% to 45.4%. Overall, 52.5% of respondents felt that childhood obesity training in residency was extremely important, and the majority of programs offered training in aspects of childhood obesity management including prevention (N = 240, 80.3%), diagnosis (N = 282, 94.3%), diagnosis of complications (N = 249, 83.3%), and treatment (N = 242, 80.9%). However, only 18.1% (N = 54) of programs had a formal childhood obesity curriculum with variability across specialties. Specifically, 35.5% of IM-Peds programs had a formal curriculum compared to only 22.6% of pediatric and 13.9% of family medicine programs (p < 0.01). Didactic instruction was the most commonly used training method but was rated as only somewhat effective by 67.9% of respondents using this method. The most frequently cited significant barrier to implementing childhood obesity training was competing curricular demands (58.5%).</p> <p>Conclusions</p> <p>While most residents receive training in aspects of childhood obesity management, deficits may exist in training quality with a minority of programs offering a formal childhood obesity curriculum. Given the high prevalence of childhood obesity, a greater emphasis should be placed on development and use of effective training strategies suitable for all specialties training physicians to care for children.</p

Trust and commitment in collective testimony
In this paper I critically discuss Miranda Frickerâs âtrust-basedâ view of collective testimonyâthat is, testimony that comes from a group speaker. At the heart of Frickerâs account is the idea that testimony involves an âinterpersonal deal of trustâ, to which the speaker contributes a commitment to âsecond-personal epistemic trustworthinessâ. Appropriating Margaret Gilbertâs concept of joint commitment, Fricker suggests that groups too can make such commitments, and hence that they, like individuals, can âenter into the second-personal relations of trust that characterise testimonyâ (Fricker 2012: 272). I argue that this choice to appropriate Gilbertâs concept of joint commitment betrays a deep problem in Frickerâs accountâa misconstrual of both the object and the subject(s) of the commitment a speaker makes in testifying. After developing this criticism, I outline an alternative way of construing the speakerâs commitment, which can be applied to both collective and individual testimony

While the gendered nature of suicide has received increased research attention, the experiences of women who have lost a man to suicide are poorly understood. Drawing on qualitative photovoice interviews with 29 women who lost a man to suicide, we completed a narrative analysis, focused on describing the ways that women constructed and accounted for their experiences. We found that womenâs narratives drew upon feminine ideals of caring for menâs health, which in turn gave rise to feelings of guilt over the manâs suicide. The women resisted holding men responsible for the suicide and tended to blame themselves, especially when they perceived their efforts to support the man as inadequate. Even when women acknowledged their guilt as illogical, they were seemingly unable to entirely escape regret and self-blame. In order to reformulate and avoid reifying feminine ideals synonymous with selflessly caring for others regardless of the costs to their own well-being, womenâs postsuicide bereavement support programs hould integrate a critical gender approach
