Introduction \ud \ud The Hewlett funded OER Research Hub (OERRH) project (REF1) works collaboratively with projects and initiatives around the world to examine the impact of open educational resources (OER). As part of expanding our collaboration base, and engage with a wider range of stakeholders, we have developed a programme of research examining librarians attitudes and practices toward OER (ranging from measuring the impact of OER to licensing) with librarians involved in the Co-PILOT project (REF2). This paper will present the findings of our research and reflect more generally on the process of collaborative research. \ud \ud Methods \ud \ud Building a network of individuals and initiatives is central to our research strategy. OERRH has developed a survey with Co-PILOT which incorporates focused questions on a range of our 11 hypotheses (including financial benefits of using OER, reflective practice, the impact on institutions of involvement in OER projects, licensing and possible challenges of using OER) in addition to developing specific questions around the curation of OER, and measuring impact. These additional questions were designed to build on the results of a range of related research, including preliminary work carried out by SCORE (De Beer, 2012), the Centre for Academic Practice & Learning Enhancement (CAPLE) at the University of Strathclyde and the Centre for Educational Technology and Interoperability Standards (CETIS) (Bueno-de-la-Fuente, 2012), and the outcome of a survey done by Nancy Graham and Jane Secker (2012). The most recent survey conducted by Taylor & Francis (2013) and related reports that examine the role of Librarians in an open access academic environment (for example Harris, 2012; TBI Communications on behalf of InTech, 2012) were also taken into account when drafting the questionnaire. \ud \ud The OERRH is currently running two versions of this questionnaire, both launched during Open Access week 2013, which have been disseminated and promoted via a range of outlets, including conferences (e.g. OpenEd 2013), OERRH channels, a range of mailing lists (e.g. IL-OER, LIS-LINK, UNESCO WSIS) and a range of social media. \ud \ud Results \ud \ud To date, our questionnaire has received a total of 295 responses. Our data collection phase will close early January 2014. OER14 represents the perfect opportunity to showcase the data gathered from this study. We also anticipate being able to report on next steps for this collaboration, including the creation of relevant case studies. This paper will also reflect on effective collaborative working practices, particularly those which have arisen through the OERRH’s focus on building networks beyond our initial collaborations. \ud \ud Discussion \ud \ud Analysis of questionnaire results will be contextualised within both the wider context of previous surveys (e.g. research carried out by Co-PILOT, the recent Taylor & Francis White Paper, SCORE library survey etc.) whilst also making comparisons with other research and data conducted as part of the OERRH project. This paper will also reflect directly on the challenges identified by librarians and indicate potential avenues for addressing these and developing a “community of practice.” (REF2)

Filtration as a method of stormwater treatment was investigated in a 3-year study. Equilibrium and kinetic studies of metals\342\200\231 capture were performed initially on twelve media. The three best performing media: peat-sand mix, compost, and zeolite were then selected for in-depth study. Upflow filters did not clog as easily as downflow, and longer-term performance was better in the upflow column. Metals were retained on the filters during anaerobiosis. Metal retention by the filters was not different from what was observed in oxygenated environments. Tests also indicated that the heavy metals of concern remain strongly bound to the particulates during long exposures at the extreme pH conditions likely to occur in receiving water sediments. Several media were tested in a pilot-scale device using water from a detention pond that drains a medium-density residential area. In this series of tests, the metals concentrations in the influent were extremely low (near the detection limit of the analysis). When the influent metals concentration was higher, such as shortly after a rain storm, the filters proved effective at removing influent concentrations down to a level of approximately 10 \342\200\223 15 μg/L. Removals to concentrations lower than that were not possible on a consistent basis.

Development in sensitive watersheds continues to pose environmental problems for receiving waters. One contributor to the long-term pollution of sensitive waterways is building and construction materials. However, the long-term effect of many building materials on the environment has not been quantified. Prior testing of these materials in the laboratory has indicated that the potential for release (primarily nutrients, lighter hydrocarbons, pesticides, and metals) is significant. Additional testing for metals\342\200\231 release from aged roofing panels also has shown that the potential for pollutant release still exists after 60 years of exposure to the environment. The data that is missing from a complete evaluation of specific building materials is behavior over the lifespan of the material, including the critical period of initial exposure. This paper provides an overview of the limited literature available on the subject, results from laboratory testing of common building materials and aged roofing panels, and an overview of the next phase of needed research. Ongoing work at campuses in two rainfall/climate zones in the U.S. have been designed fill in the data gap.
