Passive sampling methodologies were used to conduct a chemical and toxicologic assessment of organic contaminants in the surface waters of three geographically distinct agricultural watersheds. A selection of current-use agrochemicals and persistent organic pollutants, including polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and organochlorine pesticides, were targeted using the polar organic chemical integrative sampler (POCIS) and the semipermeable membrane device passive samplers. In addition to the chemical analysis, the Microtox assay for acute toxicity and the yeast estrogen screen (YES) were conducted as potential assessment tools in combination with the passive samplers. During the spring of 2004, the passive samplers were deployed for 29 to 65 d at Leary Weber Ditch, IN; Morgan Creek, MD; and DR2 Drain, WA. Chemical analysis of the sampler extracts identified the agrochemicals predominantly used in those areas, including atrazine, simazine, acetochlor, and metolachlor. Other chemicals identified included deethylatrazine and deisopropylatrazine, trifluralin, fluoranthene, pyrene, cis- and trans-nonachlor, and pentachloroanisole. Screening using Microtox resulted in no acutely toxic samples. POCIS samples screened by the YES assay failed to elicit a positive estrogenic response.

Distance education via the World Wide Web is currently being examined as a method to provide special and general education instruction in teacher preparation programs. The purpose of this study was to compare the effectiveness of traditional instructional methods in an online learning environment. Results of this study revealed that overall there were no significant differences between learning under the two conditions. That is, student academic outcomes were the same when instruction was delivered in a traditional classroom or through an online learning environment. Some advantage was found to online discussions in contrast to face-to-face discussions. Traditional instructional methods, such as those used in this study, produce similar academic outcomes when delivered through online learning environments. The implications of these results for teacher preparation practice are discussed.

At a time of significant upheaval in American health policy, maintaining a focus on a "North Star" is critical. For implementation science, this star is the knowledge base on how to optimally disseminate evidence related to health and health care, how to implement interventions to improve care within the many settings where people receive health care and make health-related decisions, and how to improve the health of the global population. To that end, the end of 2016 brought over 1100 engaged and activated "disciples of D & I" to Washington, DC for the 9 th Annual Conference on the Science of Dissemination and Implementation in Health. Once again, the accompanying abstracts in this issue demonstrate the breadth, depth and vigor of this continually expanding and evolving subset of health research. During three dynamic plenaries with rows and rows of filled seats and packed concurrent sessions presenters and attendees shared findings, raised methodologic and other challenges, and discussed future priorities, trends, and next steps for this community of research. For the third year in a row, we were buoyed by a strong partnership, co-led by AcademyHealth and the National Institutes of Health (NIH), with co-sponsorship from others committed to implementation science: the Agency for Healthcare Research and Quality (AHRQ), the Patient Centered Outcomes Research Institute (PCORI), the Robert Wood Johnson Foundation (RWJF), and the US Department of Veterans Affairs (VA). The multidisciplinary program planning committee informed the development of the key themes for the conference, identified the plenary sessions topics and speakers, established track leads to manage the review process for concurrent panels, papers, and posters, and convened a scientific advisory panel to advise on the overall conference, thus ensuring a robust, inclusive, and rigorous process. Together, the opening keynote address and the three plenary panel sessions set a tone of innovation and dialogue, raised critical issues, surfaced different perspectives, and ensured that follow on lunchtime and hallway discussions delved deeper into thorny challenges facing the field. Roy Rosin, Chief Innovation Officer for the University of Pennsylvania's Perelman School of Medicine, introduced the audience to a range of methods for rapid testing, innovation in healthcare delivery, and lessons learned from other industries to maximize potential of new practices to be scaled-up. Each of the three plenary panels presented a general discussion on a high priority challenge for dissemination and implementation (D & I) research. A panel on the balance between intervention and implementation fidelity and local adaptation touched on the very real dynamic that is playing out in communities across this country as policy and payment changes are driving providers and others to seek new ways to solve the challenges in their particular contexts. A panel on the longerterm decisions around sustainment or de-implementation of interventions could not be more timely given the "im...
