Environmental Research Letters. 14(12), (2019): 124060, doi:10.1088/1748-9326/ab5abc.Recent research has quantified the contributions of CO2 and CH4 emissions traced to the products of major fossil fuel companies and cement manufacturers to global atmospheric CO2, surface temperature, and sea level rise. This work has informed societal considerations of the climate responsibilities of these major industrial carbon producers. Here, we extend this work to historical (1880–2015) and recent (1965–2015) acidification of the world's ocean. Using an energy balance carbon-cycle model, we find that emissions traced to the 88 largest industrial carbon producers from 1880–2015 and 1965–2015 have contributed ~55% and ~51%, respectively, of the historical 1880–2015 decline in surface ocean pH. As ocean acidification is not spatially uniform, we employ a three-dimensional ocean model and identify five marine regions with large declines in surface water pH and aragonite saturation state over similar historical (average 1850–1859 to average 2000–2009) and recent (average 1960–1969 to average of 2000–2009) time periods. We characterize the biological and socioeconomic systems in these regions facing loss and damage from ocean acidification in the context of climate change and other stressors. Such analysis can inform societal consideration of carbon producer responsibility for current and near-term risks of further loss and damage to human communities dependent on marine ecosystems and fisheries vulnerable to ocean acidification.The approach of using equation (1) benefited from discussions with Myles R Allen (University of Oxford) and Inez Fung (University of California, Berkeley).

Library Resources Utilization: determining high yield resources for medical students

The University of Hawaii (UH) Health Sciences Library (HSL) provides a variety of resources critical for science and medical education at the UH, John A. Burns School of Medicine (JABSOM). These resources are accessible by all of the UH students and faculty, including affiliated sites. To provide tailored services for medical students, their educational needs must be identified. Currently, there is no standardized system that evaluates this. The usage data of HSL resources is collected through the number of log-in’s through the UH library system by all of UH Manoa users. As such, it does not distinguish between medical students and other UH users. We propose that resource utilization by medical students differs from those utilized by other UH users. The objectives of the survey were three-fold: 1) To identify utilization of HSL resources by medical students; 2) Compare the pattern of utilization of the HSL resources by medical students with UH Manoa users by comparing our survey results to 2021 HSL usage data; and 3) To identify utilization of resources not available through HSL system. An online survey was emailed to all current JABSOM medical students. The six item survey included two likert scale questions regarding utilization of library resources available and not available through the JABSOM library. Items were assigned a numerical value; Never =1, Rarely=2, Sometimes=3, Very Often=4, and Always=5 and an average value was calculated for each resource. The remaining four items were open-ended. Sixty-six total responses were obtained with 21% first years, 35% second years, 18% third years, and 26% fourth years. The most utilized HSL resources were Access Medicine, PubMed, Textbooks, and Clinical Keys. The least used library resources were Health and Psychology instruments, Natural Medicine database, JoVE, and Psych Articles. For both medical students and UH Manoa users, Access Medicine and Clinical Key were among the most used, whereas Health and Psych instruments, JoVE, and Natural Medicine database were among the least used. On the other hand, Cochrane was ranked higher and Psych Articles was ranked lower in overall relative usage among medical students compared to the relative ranking among UH Manoa users. The most utilized non-HSL resources among medical students were Boards and Beyond, Sketchy, Pathoma, and AMBOSS, respectively. In conclusion, our study assessed medical student resource utilization of library and non-library resources at the JABSOM library. The rank order of the utilized resources were similar between medical students and UH Manoa users, with some exceptions. The results identified the utility of non-HSL resources, suggesting they are key supplemental tools in medical education. Further studies should investigate why some resources are used more or less to guide efforts in improving availability of these services

Medical Students & Wikipedia Editing: Implications for reinforcing & improving information literacy skills

PosterThis poster presents the results of a pilot study that examines the use of Wikipedia editing with first-year medical students as an intervention for reinforcing and improving information literacy skills. The study took place at the University of Hawaii at Manoa, John A. Burns School of Medicine with students from the MD class of 2022. Methods: The students learned to edit and contribute to Wikipedia over a period of three months from August to November 2018. At the conclusion of the editing experience, students were asked to respond to a retrospective pre/post survey to assess the impact of Wikipedia editing on various information literacy skills. Results: Data gathered from the survey show a statistically significant improvement in the students' perceived information literacy skills

Climate Change and Social Conflicts

This article outlines the role of globalized mass media in the perception of environmental and social threats and its reciprocal conditionality in the globalized society. It examines the reasons why the global environmental crisis will not lead to a world-wide environmental movement for change of the basic imperatives of the world economicpolitical system. Coherency between globalized mass media and wide-spreading of consumer lifestyle exists despite the fact that it deepens the devastation of environment and social conflicts. Globalized mass media owned by transnational corporations are not only a part of the current global economic-political system, but also the prerequisite of its creation and existence, as well as social contradictions and conflicts
