    “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

    Get PDF
    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].

    Peril, Pandemic, and Crisis: Asian American Studies

    Get PDF
    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
