“It falls on all our shoulders”: Overcoming Barriers to Delivering Sex Education in West Texas Schools
BACKGROUND: Many racial, socioeconomic, and geographic disparities exist in rates of teen birth and sexually transmitted infections. Increasing access to comprehensive sex education is one risk reduction strategy for these outcomes, yet access to and quality of sex education in schools often falls far below recommended standards, particularly in Texas. The current exploratory study examines barriers to effectively delivering sex education in West Texas schools and identifies strategies to help overcome these barriers. METHODS: In-depth interviews with school leaders and health education professionals (n=4) were conducted to understand teen sexual health needs in West Texas. Interviews were analyzed using descriptive coding, memoing, and quote matrices to interpret the data. RESULTS: Participants identified a number of policy-, organizational-, and interpersonal-level barriers to delivering sex education in public schools. School personnel experienced intense time pressures, a lack of institutional support, and tension with parents. Many expressed a desire to work more collaboratively with parents and participants acknowledged the important role of school health advisory councils (SHACs). CONCLUSIONS: School personnel face complex challenges at multiple levels when attempting to deliver sex education in public schools. Despite these challenges, SHACs represent a valuable opportunity for communities to work collaboratively to improve sex education in public schools
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 – 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
Mathematical Models and Biological Meaning: Taking Trees Seriously
We compare three basic kinds of discrete mathematical models used to portray
phylogenetic relationships among species and higher taxa: phylogenetic trees,
Hennig trees and Nelson cladograms. All three models are trees, as that term is
commonly used in mathematics; the difference between them lies in the
biological interpretation of their vertices and edges. Phylogenetic trees and
Hennig trees carry exactly the same information, and translation between these
two kinds of trees can be accomplished by a simple algorithm. On the other
hand, evolutionary concepts such as monophyly are represented as different
mathematical substructures are represented differently in the two models. For
each phylogenetic or Hennig tree, there is a Nelson cladogram carrying the same
information, but the requirement that all taxa be represented by leaves
necessarily makes the representation less efficient. Moreover, we claim that it
is necessary to give some interpretation to the edges and internal vertices of
a Nelson cladogram in order to make it useful as a biological model. One
possibility is to interpret internal vertices as sets of characters and the
edges as statements of inclusion; however, this interpretation carries little
more than incomplete phenetic information. We assert that from the standpoint
of phylogenetics, one is forced to regard each internal vertex of a Nelson
cladogram as an actual (albeit unsampled) species simply to justify the use of
synapomorphies rather than symplesiomorphies.Comment: 15 pages including 6 figures [5 pdf, 1 jpg]. Converted from original

Peril, Pandemic, and Crisis: Asian American Studies
Hello and Welcome to our Zine!! We are so happy you stopped by! :) We were presented the opportunity to create a zine on Asian American studies through Josen Diaz’s ETHN course. Although this started out as a project, it became so much more to our group. We had the opportunity to explore different Asian American cultures, their history, and their influence on American culture and politics. This project allowed us to relate all of the historical readings from the Chinese Exclusion Act and the world wars to events that occur today. Over the semester, we developed our overall knowledge on ethnic studies and expanded worldviews; we hope that reading this zine will allow you to do the same. In this document, we attempted to construct a creative medium which conveys all of our thoughts and ideas on the subject matter at hand. The three of us are juniors at the University of San Diego studying under varying disciplines. We all come from different parts of California and brought different perspectives to the table when brainstorming and working on the zine each week. Before reading this Zine, we want all readers to understand that the opinions and viewpoints shared here are our subjective views relating to academic texts. We are by no means authorities on these topics, and we encourage you to do your own research to expand your personal knowledge. This is a great place to begin or continue one\u27s academic journey into Asian American studies, but it is not intended to be used as a basis of knowledge or a foundational source. We hope that you all enjoy reading this zine and find its contents interesting and informative.https://digital.sandiego.edu/ethn-zines/1004/thumbnail.jp

Strategies for Scaling and Sustaining OER Initiatives
Designed around an OER Scaling and Sustainability Playbook, this workshop invites OER veterans and newbies to explore: 1) What are the common challenges around growing OER adoption, and what are successful strategies for tackling these challenges at your institution? And 2) What models are institutions pursuing to sustain their OER initiatives, and which might be a good fit for you? During the session, you’ll use the Playbook as a diagnostic tool to identify strategies to help you achieve your goals for making a significant impact with OER. We’ll also invite the group to recommend additional strategies and tactics to broaden the Playbook as a useful resource for the OER community
