Minimizing Vessel Strikes to Endangered Whales: A Crash Course in Conservation Science and Policy
The North Atlantic right whale is one of the most endangered of all large whales: about 350-400 individuals remain. Species recovery is, in part, contingent on reducing vessel-strike mortality. Our science-based conservation program resulted in three efforts specifically designed to minimize the risk of lethal vessel-strikes of endangered baleen whales without compromising vessel navigation and safety. In Atlantic Canada, the Bay of Fundy Traffic Separation Scheme (TSS) was relocated to reduce the risk of lethal vessel strikes by 90% where the original outbound lane of the TSS intersected the Right Whale Conservation Area, and an Area To Be Avoided (ATBA) adopted for Roseway Basin has demonstrated an 82% reduction in the risk of lethal vessel-strikes. In the Gulf of Maine, the Boston TSS through the Stellwagen Bank National Marine Sanctuary was relocated to reduce the overlap between vessels and endangered baleen whales by ~81% and by ~58% for right whales alone. This rerouting of vessels for whale conservation, as sanctioned by the International Maritime Organization, sets a precedent for national and international marine conservation policy by providing vessels with direct actions they can take to protect endangered whales â both regulated (TSS) and voluntary (ATBA). This demonstrate that despite contentious conditions, effective science-driven policy tools for conservation can be identified, made available, and implemented. The science also provides the quantitative means to measure policy efficacy through monitoring of vessel compliance and, in some cases, can increase compliance through improved real-time communications regarding whale locations in high-risk areas

Reuse as heuristic : from transmission to nurture in learning activity design
In recent years a combination of ever more flexible and sophisticated Web technologies and an explosion in the quantity of online content has sparked learning technologists around the world to pursue the promise of the 'reusable learning object' or RLO with the idea that RLOs could be reused in different educational contexts, thereby providing greater overall flexibility and return on investment. In 2002 the ACETS Project undertook a three-year study in the UK to investigate whether RLOs worked in practice and how the pursuit of reuse affected the teacher and their teaching. Teachers working in healthcare-related subjects in Higher and Further Education were asked to create an original learning design or activity from third-party digital resources and to reflect both on the process and its outcomes. The expectation was that teachers would be the ones selecting and reusing third-party materials. This paper describes how one of the ACETS exemplifiers reinterpreted this remit, challenged the anticipated transmissive model of learning, and instead, gave their students an opportunity to create their own original learning designs and learning activities from third-party digital resources. By describing the educational enhancements, the resulting heightened levels of critical thinking, and sensitivity to patient needs, 'reuse' will be shown to be an effective heuristic for student self-direction and professional development
"You're doing great. Keep doing what you're doing": socially supportive communication during first-generation college students' socialization
The experiences of first-generation college students (FGCS) are marked by high levels of stress and uncertainty as they navigate the transition to college. This study uses the organizational assimilation model to explore FGCSâ transition to college by temporally analyzing multiple sources and types of socially supportive communication found in interviews with 28 FGCS in their first semester at a four-year university. Findings suggest that during anticipatory socialization, FGCS primarily engaged in informational and instrumental social support interactions; in the encounter phase of socialization, FGCS (while still engaging in informational and instrumental support interactions) also engaged in appraisal and emotional support interactions. Findings also illuminate the ways in which FGCS embodied the role of pioneers, even early in the socialization process, suggesting important implications for their role not only as receivers of social support, but as agents of social support
The two stories of the habitus/structure relation and the riddle of reflexivity: A metaâtheoretical reappraisal
This article argues that two key puzzles arising from the theories of Bourdieu are inter-related. One is the question of how Bourdieu analyses the relationship between structure and habitus, and the other is the place of reflexivity in Bourdieu's work. We contend that it is only by carefully analysing Bourdieu's theoretical structure to grasp the relationship between these elements that one can understand whether or not his work offers useful resources for analysing the relation between routine action and self-reflection. This paper argues that there are two narrations of the structure/habitus relation in Bourdieu's work, and that the concept of self-reflective subjectivity is a residual element of the first narration and does not appear in the second. We then contend that this residual and under-developed concept of self-reflective subjectivity should not be confused with Bourdieu's analysis of epistemic reflexivity. These moves allow us to contribute to ongoing debates about the relation between routine action and self-reflection by arguing that the concept of the âreflexive habitusâ â which some have argued is characteristic of social agents in high/late modernity â is both conceptually confused and is not a logical extension of Bourdieu's theories. In this way we try to clear the ground for more productive ways of thinking about routine action and self-reflection
Approval Plan Profile Assessment in Two Large ARL Libraries: University of Illinois at Urbana-Champaign and Pennsylvania State University
Two Association of Research Libraries member libraries, the University of Illinois at UrbanaâChampaign (UIUC) and Pennsylvania State University (Penn State), evaluated their monograph acquisition approval plan profiles to answer basic questions concerning use, cost effectiveness, and coverage. Data were collected in tandem from vendors and local online systems to track book receipt, item circulation, and overlap between plans. The study period was fiscal year 2005 (July 1, 2004âJune 30, 2005) for the approval plan purchasing data, and circulation use data were collected from July 1, 2004, through March 31, 2007, for both UIUC and Penn State. Multiple data points were collected for each title, including author, title, ISBN, publisher, Library of Congress classification number, purchase price, and circulation data. Results of the study measured the cost-effectiveness of each plan by subject and publisher, analyzed similarities and differences in use, and examined the overlap between the two approval plans. The goals were to establish a benchmark for consistently evaluating approval plan profile effectiveness and to provide a reproducible method with baseline data that will allow other libraries to collect comparable data and conduct their own studies
Ocean acidification in the surface waters of the Pacific-Arctic boundary regions
Author Posting. © The Oceanography Society, 2015. This article is posted here by permission of The Oceanography Society for personal use, not for redistribution. The definitive version was published in Oceanography 28, no. 2 (2015): 122-135, doi:10.5670/oceanog.2015.36.The continental shelves of the Pacific-Arctic Region (PAR) are especially vulnerable to the effects of ocean acidification (OA) because the intrusion of anthropogenic CO2 is not the only process that can reduce pH and carbonate mineral saturation states for aragonite (Ωarag). Enhanced sea ice melt, respiration of organic matter, upwelling, and riverine inputs have been shown to exacerbate CO2 -driven ocean acidification in high-latitude regions. Additionally, the indirect effect of changing sea ice coverage is providing a positive feedback to OA as more open water will allow for greater uptake of atmospheric CO2 . Here, we compare model-based outputs from the Community Earth System Model with a subset of recent ship-based observations, and take an initial look at future model projections of surface water Ωarag in the Bering, Chukchi, and Beaufort Seas. We then use the model outputs to define benchmark years when biological impacts are likely to result from reduced Ωarag. Each of the three continental shelf seas in the PAR will become undersaturated with respect to aragonite at approximately 30-year intervals, indicating that aragonite undersaturations gradually progress upstream along the flow path of the waters as they move north from the Pacific Ocean. However, naturally high variability in Ωarag may indicate higher resilience of the Bering Sea ecosystem to these low-Ωarag conditions than the ecosystems of the Chukchi and the Beaufort Seas. Based on our initial results, we have determined that the annual mean for Ωarag will pass below the current range of natural variability in 2025 for the Beaufort Sea and 2027 for the Chukchi Sea. Because of the higher range of natural variability, the annual mean for Ωarag for the Bering Sea does not pass out of the natural variability range until 2044. As Ωarag in these shelf seas slips below the present-day range of large seasonal variability by mid-century, the diverse ecosystems that support some of the largest commercial and subsistence fisheries in the world may be under tremendous pressure.This project was funded by the National Science
