Using Residential History and Groundwater Modeling to Examine Drinking Water Exposure and Breast Cancer
BACKGROUND. Spatial analyses of case-control data have suggested a possible link between breast cancer and groundwater plumes in upper Cape Cod, Massachusetts. OBJECTIVE. We integrated residential histories, public water distribution systems, and groundwater modeling within geographic information systems (GIS) to examine the association between exposure to drinking water that has been contaminated by wastewater effluent and breast cancer. METHODS. Exposure was assessed from 1947 to 1993 for 638 breast cancer cases who were diagnosed from 1983 to 1993 and 842 controls; we took into account residential mobility and drinking water source. To estimate the historical impact of effluent on drinking water wells, we modified a modular three-dimensional finite-difference groundwater model (MODFLOW) from the U.S. Geological Survey. The analyses included latency and exposure duration. RESULTS. Wastewater effluent impacted the drinking water wells of study participants as early as 1966. For > 0-5 years of exposure (versus no exposure), associations were generally null. Adjusted odds ratios (AORs) for > 10 years of exposure were slightly increased, assuming latency periods of 0 or 10 years [AOR = 1.3; 95% confidence interval (CI), 0.9-1.9 and AOR = 1.6; 95% CI, 0.8-3.2, respectively]. Statistically significant associations were estimated for ever-exposed versus never-exposed women when a 20-year latency period was assumed (AOR = 1.9; 95% CI, 1.0-3.4). A sensitivity analysis that classified exposures assuming lower well-pumping rates showed similar results. CONCLUSION. We investigated the hypothesis generated by earlier spatial analyses that exposure to drinking water contaminated by wastewater effluent may be associated with breast cancer. Using a detailed exposure assessment, we found an association with breast cancer that increased with longer latency and greater exposure duration.National Cancer Institute (5R03CA119703-02); National Institute of Environmental Health Sciences (5P42 ES007381
A case history of use and management of the Baton Rouge fresh water aquifer system
The Southern Hills Aquifer located in southeastern Louisiana has provided residents of Baton Rouge and surrounding communities with high-quality, fresh drinking water for many decades. However in recent years increasing pumping rates, evidence of saltwater intrusion, and concerns about the equitable and sustainable use of the aquifer have led residents and researchers to begin to examine more critically how groundwater is managed in this area. Louisiana is one of only six states without a groundwater management plan, and to date, the officials in charge of monitoring the Southern Hills Aquifer have not developed any guidelines for limiting withdrawal. This thesis presents a detailed case study of the use and management of the Southern Hills Aquifer in Baton Rouge. Specifically, these research questions will be addressed: 1) What is the state of the Southern Hills Aquifer system concerning salt-water intrusion?; 2) What is the current State management structure for the aquifer? 3) How may a new organization based on the principles of collaborative environmental planning improve the structure of groundwater management in Baton Rouge? A review of technical reports by the US Geological Survey and others indicates that saltwater intrusion into the aquifer has occurred and is spreading at an increasing rate. The state groundwater management structure includes two organizations. Legal responsibility for management of the aquifer lies with the Louisiana State Department of Natural Resources (DNR) through the Office of the Commissioner of Conservation, while the Capital Area Groundwater Conservation Commission appears to function as a permanent task force, holding quarterly public meetings concerning groundwater issues. In 2011, a small group of residents formed the Baton Rouge Citizens to Save Our Water, Inc. The group seeks to promote collaborative environmental planning principles and, as a first step, is working to disseminate technical information about the Aquifer and to encourage residents to lobby for a groundwater management plan that limits industries’ use of the water. The case study includes a detailed timeline of the interactions between the citizens group and state groundwater officials. A review of subsequent public statements by the officials indicates that the citizen group has been successful in moving the policy debate toward a more comprehensive groundwater management plan

Ge-Doped microstructured multicorefiber for customizable supercontinuum generation
Supercontinuum generation in a multicore fiber in which several uncoupled cores
were doped with dissimilar concentrations of germanium was studied experimentally.
Germanium doping provided control over the separation between the zero-dispersion
wavelength and the 1064-nm wavelength of a Q-switched Nd:YAG pump laser. Supercontinua
generated independently in each core of the same piece of fiber displayed clear
and repeatable differences due to the influence of germanium doping on refractive index and
four-wave mixing. The spectral evolution of the subnanosecond pump pulses injected into
the different cores was accurately reproduced by numerical simulations
Intensive Short-Term Dynamic Psychotherapy: A Systematic Review and Meta-analysis of Outcome Research
Abstract. Based on over forty years of videotaped case-based research, Habib Da-vanloo of McGill University, Canada, discovered some of the core ingredients that can enable direct and rapid access to the unconscious in resistant3 patients, patients with functional disorders, and patients with fragile character structure. We will describe here some of the main research findings that culminated in his description of a central thera-peutic process involved in the intensive short-term dynamic psychotherapy (ISTDP) model. We will also describe the evolution of the technique over the past thirty years and summarize the empirical base for Davanloo’s ISTDP
A Novel Approach to Multimedia Ontology Engineering for Automated Reasoning over Audiovisual LOD Datasets
Multimedia reasoning, which is suitable for, among others, multimedia content
analysis and high-level video scene interpretation, relies on the formal and
comprehensive conceptualization of the represented knowledge domain. However,
most multimedia ontologies are not exhaustive in terms of role definitions, and
do not incorporate complex role inclusions and role interdependencies. In fact,
most multimedia ontologies do not have a role box at all, and implement only a
basic subset of the available logical constructors. Consequently, their
application in multimedia reasoning is limited. To address the above issues,
VidOnt, the very first multimedia ontology with SROIQ(D) expressivity and a
DL-safe ruleset has been introduced for next-generation multimedia reasoning.
In contrast to the common practice, the formal grounding has been set in one of
the most expressive description logics, and the ontology validated with
industry-leading reasoners, namely HermiT and FaCT++. This paper also presents
best practices for developing multimedia ontologies, based on my ontology

Is affect experiencing therapeutic in major depressive disorder? Examining associations between affect experiencing and changes to the alliance and outcome in intensive short-term dynamic psychotherapy.
Affect experiencing (AE), defined as the facilitation of client in-session bodily arousal and visceral experiencing of affect, is a distinct theoretical process presumed to contribute to therapeutic improvement. This study examined the role of AE in the treatment of major depressive disorder by exploring its association to client distress and therapeutic alliance on a session-by-session basis. A case series design was used to conduct an intensive analysis of the treatment process of 4 clients who received time-limited intensive short-term dynamic psychotherapy, 2 of whom were considered "recovered" and 2 who showed "no change" based upon posttreatment outcomes. Consistent with our hypothesis, we found that cross-correlations between AE and client distress discriminated between "recovered" and "no change" clients. In "recovered" clients, there was evidence that higher in-session peak affect experience was associated with reduced distress 7 days later. The results did not provide consistent evidence for a reverse effect, showing that lower distress during the preceding week predicted higher AE in that session. Finally, there was evidence that AE is an in-session activity that can promote the strengthening of the therapeutic alliance. These collective findings suggest that AE is an important treatment process that contributes to alliance formation and psychotherapeutic improvement. Clinical implications include further evidence that psychodynamic therapists can utilize AE as an active change ingredient for depression
Survey of Infections Transmissible Between Baboons and Humans, Cape Town, South Africa
Baboons on South Africa’s Cape Peninsula come in frequent contact with humans. To determine potential health risks for both species, we screened 27 baboons from 5 troops for 10 infections. Most (56%) baboons had antibodies reactive or cross-reactive to human viruses. Spatial overlap between these species poses low but potential health risks
