The Hurricane Sandy Place Report: Evacuation Decisions, Housing Issues and Sense of Community
Hurricane Sandy was one of the largest storms on record, sweeping through the eastern seaboard of the United States with a massive diameter twice the size of Hurricane Katrina. Although wind speeds did not match those of Katrina, the combination of high tide at landfall and the lunar phase resulted in exceptionally high storm surges. Catastrophic storms such as Hurricane Sandy can have devastating effects on many aspects of human life and the environment, undermining economic activity, crippling critical infrastructure, and disrupting hundreds of thousands of lives for weeks, months, or even years. The Sandy Child and Family Health (S-CAFH) Study was designed to describe and analyze the impacts of the storm on the residents of New Jersey, identifying those needs which emerged and those which are still pressing. The research team – a partnership of faculty and research staff from Rutgers University, New York University, Columbia University, and Colorado State University – randomly selected and surveyed 1,000 residents of New Jersey’s “Disaster Footprint,” representing the experiences of 1 million New Jersey residents living in or near those coastal areas of the state most directly exposed to the storm. The primary focus of this Briefing Report, the first in a series of four thematic reports, is to document the storm’s impact on PLACE in New Jersey residents’ lives, with a particular emphasis on Sandy’s effect on people’s homes and housing decisions

The Hurricane Sandy Person Report: Disaster Exposure, Health Impacts, Economic Burden, and Social Well-Being
The impact a disaster has on the health of a population can be described as having a “dose-response” relationship: the larger the “dose” of the disaster, the greater the health impact or “response” among those individuals and communities exposed. This PERSON Briefing Report describes the impact of Hurricane Sandy (the dose) on the health and well-being of adults and children exposed to the storm (the response). Data for the report are drawn from the baseline survey of the Sandy Child and Family Health (S-CAFH) Study, an observational cohort study of nearly 1,000 randomly-selected New Jersey residents who were living in areas of the state exposed to the storm in 2012. Participants in the study represent over 1 million people living in Sandy’s “Disaster Footprint,” the hurricane-exposed portions of the state. This report describes and examines several critical aspects of individual health and well-being that may be associated with the storm, including: 1. Physical health of adults; 2. Psychological and emotional health of adults; 3. Social and economic health of adults; 4. Health and well-being of children; and 5. The association between disaster exposure and individual outcomes
Comparative genomics of Cluster O mycobacteriophages
Mycobacteriophages - viruses of mycobacterial hosts - are genetically diverse but morphologically are all classified in the Caudovirales with double-stranded DNA and tails. We describe here a group of five closely related mycobacteriophages - Corndog, Catdawg, Dylan, Firecracker, and YungJamal - designated as Cluster O with long flexible tails but with unusual prolate capsids. Proteomic analysis of phage Corndog particles, Catdawg particles, and Corndog-infected cells confirms expression of half of the predicted gene products and indicates a non-canonical mechanism for translation of the Corndog tape measure protein. Bioinformatic analysis identifies 8-9 strongly predicted SigA promoters and all five Cluster O genomes contain more than 30 copies of a 17 bp repeat sequence with dyad symmetry located throughout the genomes. Comparison of the Cluster O phages provides insights into phage genome evolution including the processes of gene flux by horizontal genetic exchange
A Broadly Implementable Research Course in Phage Discovery and Genomics for First-Year Undergraduate Students
Engaging large numbers of undergraduates in authentic scientific discovery is desirable but difficult to achieve. We have developed a general model in which faculty and teaching assistants from diverse academic institutions are trained to teach a research course for first-year undergraduate students focused on bacteriophage discovery and genomics. The course is situated within a broader scientific context aimed at understanding viral diversity, such that faculty and students are collaborators with established researchers in the field. The Howard Hughes Medical Institute (HHMI) Science Education Alliance Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) course has been widely implemented and has been taken by over 4,800 students at 73 institutions. We show here that this alliance-sourced model not only substantially advances the field of phage genomics but also stimulates students’ interest in science, positively influences academic achievement, and enhances persistence in science, technology, engineering, and mathematics (STEM) disciplines. Broad application of this model by integrating other research areas with large numbers of early-career undergraduate students has the potential to be transformative in science education and research training

An inclusive Research and Education Community (iREC) model to facilitate undergraduate science education reform
Funding: This work was supported by Howard Hughes Medical Institute grants to DIH is GT12052 and MJG is GT15338.Over the last two decades, there have been numerous initiatives to improve undergraduate student outcomes in STEM. One model for scalable reform is the inclusive Research Education Community (iREC). In an iREC, STEM faculty from colleges and universities across the nation are supported to adopt and sustainably implement course-based research – a form of science pedagogy that enhances student learning and persistence in science. In this study, we used pathway modeling to develop a qualitative description that explicates the HHMI Science Education Alliance (SEA) iREC as a model for facilitating the successful adoption and continued advancement of new curricular content and pedagogy. In particular, outcomes that faculty realize through their participation in the SEA iREC were identified, organized by time, and functionally linked. The resulting pathway model was then revised and refined based on several rounds of feedback from over 100 faculty members in the SEA iREC who participated in the study. Our results show that in an iREC, STEM faculty organized as a long-standing community of practice leverage one another, outside expertise, and data to adopt, implement, and iteratively advance their pedagogy. The opportunity to collaborate in this manner and, additionally, to be recognized for pedagogical contributions sustainably engages STEM faculty in the advancement of their pedagogy. Here, we present a detailed pathway model of SEA that, together with underpinning features of an iREC identified in this study, offers a framework to facilitate transformations in undergraduate science education.Peer reviewe

established researchers in the field. The Howard Hughes Medical Institute (HHMI) Science Education Alliance Phage Hunters
Advancing Genomics and Evolutionary Science (SEA-PHAGES) course has been widely implemented and has been taken by over
4,800 students at 73 institutions. We show here that this alliance-sourced model not only substantially advances the field of
phage genomics but also stimulates students’ interest in science, positively influences academic achievement, and enhances persistence

IMPORTANCE: Engagement of undergraduate students in scientific research at early stages in their careers presents an opportunity
to excite students about science, technology, engineering, and mathematics (STEM) disciplines and promote continued interests
in these areas. Many excellent course-based undergraduate research experiences have been developed, but scaling these to a
broader impact with larger numbers of students is challenging. The Howard Hughes Medical Institute (HHMI) Science Education
Alliance Phage Hunting Advancing Genomics and Evolutionary Science (SEA-PHAGES) program takes advantage of the
huge size and diversity of the bacteriophage population to engage students in discovery of new viruses, genome annotation, and
comparative genomics, with strong impacts on bacteriophage research, increased persistence in STEM fields, and student selfidentification
with learning gains, motivation, attitude, and career aspirations
Models of classroom assessment for course-based research experiences
Course-based research pedagogy involves positioning students as contributors to authentic research projects as part of an engaging educational experience that promotes their learning and persistence in science. To develop a model for assessing and grading students engaged in this type of learning experience, the assessment aims and practices of a community of experienced course-based research instructors were collected and analyzed. This approach defines four aims of course-based research assessment—(1) Assessing Laboratory Work and Scientific Thinking; (2) Evaluating Mastery of Concepts, Quantitative Thinking and Skills; (3) Appraising Forms of Scientific Communication; and (4) Metacognition of Learning—along with a set of practices for each aim. These aims and practices of assessment were then integrated with previously developed models of course-based research instruction to reveal an assessment program in which instructors provide extensive feedback to support productive student engagement in research while grading those aspects of research that are necessary for the student to succeed. Assessment conducted in this way delicately balances the need to facilitate students’ ongoing research with the requirement of a final grade without undercutting the important aims of a CRE education
Aid on Demand: African Leaders and the Geography of China's Foreign Assistance
This article investigates whether China’s foreign aid is particularly prone to political capture by political leaders of aid-receiving countries. Specifically, we examine whether more Chinese aid is allocated to the political leaders’ birth regions and regions populated by the ethnic group to which the leader belongs, controlling for indicators of need and various fixed effects. We have collected data on 117 African leaders’ birthplaces and ethnic groups and geocoded 1,650 Chinese development finance projects across 3,097 physical locations committed to Africa over the 2000-2012 period. Our econometric results show that current political leaders’ birth regions receive substantially larger financial ows from China than other regions. On the contrary, when we replicate the analysis for the World Bank, our regressions with region-fixed effects show no evidence of such favoritism. For Chinese and World Bank aid alike, we also find no evidence that African leaders direct more aid to areas populated by groups who share their ethnicity, when controlling for region-fixed effects
