The Relevance of Governance Institutions in Marine Protected Area Design and Management: Lessons from Northeastern Iloilo, Philippines  [cached]
Pepito Fernandez, Jr.
Science Diliman , 2006,
Abstract: The experience of the Philippines on decentralized marine protected area (MPA) management can providean instructive purview of nature-society processes and politics of scale in a post-colonial and tropicalmarine fisheries setting. This paper examines and analyzes the comparative advantage and limitationsin adopting government regulation, community-based initiatives and co-management arrangements (i.e.,rules) in designing and implementing MPAs to meet conservation and livelihood goals. The theoreticaldiscussion will be enriched by providing relevant contextual factors (i.e., biophysical setting, communityattributes and institutional setting) from secondary literature and social science field data gathered fromMarch to December 2005 in various coastal municipalities in Northeastern Iloilo Province, Philippines.The study site contains 17 MPAs established between 1994 to 2004 with diverse backgrounds andprofiles, and are governed by various alliances (state and/or non-state actors) in different scales (i.e.,local to international). The paper will argue that no single institutional arrangement is likely to beeffective in addressing all the circumstances surrounding MPA design and implementation. But in themilieu of a depleted natural resource base, and the continued deterioration of the livelihood and healthof poor people, environmental protection of MPAs and municipal fishing grounds of subsistence fishersshould be prioritized by various actors and policy networks.

Abstract: Pre-tested, self-administered questionnaires were sent by email to all Fogarty alumni at the MAKCHS (mentors) and each of them was requested to complete and email back the questionnaire. In addition to training level and number of mentors, the questionnaires had open-ended questions covering themes such as; status of mentorship, challenges faced by mentors and strategies to improve and sustain mentorship within MAKCHS. Similarly, open-ended questionnaires were sent and received by email from all graduate students (mentees) registered with the Uganda Society for Health Scientists (USHS). Qualitative data from mentors and mentees was analyzed manually according to the pre-determined themes.Twenty- two out of 100 mentors responded (14 email and 8 hard copy responses). Up to 77% (17/22) of mentors had Master's-level training and only 18% (4/22) had doctorate-level training. About 40% of the mentors had ≥ two mentees while 27% had none. Qualitative results showed that mentors needed support in terms of training in mentoring skills and logistical/financial support to carry out successful mentorship. Junior scientists and students reported that mentorship is not yet institutionalized and it is currently occurring in an adhoc manner. There was lack of awareness of roles of mentors and mentees. The mentors mentioned the limited number of practicing mentors at the college and thus the need for training courses and guidelines for faculty members in regard to mentorship at academic institutions.Both mentors and mentees were willing to improve mentorship practices at MAKCHS. There is need for institutional commitment to uphold and sustain the mentorship best practices. We recommend a collaborative approach by the stakeholders in global health promotion to build local capacity in mentoring African health professionals.Mentoring, defined as a partnership in personal and professional growth and development, is a core component of medical education and career success [1,2].

The cusped hyperbolic census is complete  [PDF]

Computer Science , 2014,
Abstract: From its creation in 1989 through subsequent extensions, the widely-used "SnapPea census" now aims to represent all cusped finite-volume hyperbolic 3-manifolds that can be obtained from <= 8 ideal tetrahedra. Its construction, however, has relied on inexact computations and some unproven (though reasonable) assumptions, and so its completeness was never guaranteed. For the first time, we prove here that the census meets its aim: we rigorously certify that every ideal 3-manifold triangulation with <= 8 tetrahedra is either (i) homeomorphic to one of the census manifolds, or (ii) non-hyperbolic. In addition, we extend the census to 9 tetrahedra, and likewise prove this to be complete. We also present the first list of all minimal triangulations of all census manifolds, including non-geometric as well as geometric triangulations.
The future of census coverage surveys  [PDF]

Statistics , 2008, DOI: 10.1214/193940307000000464
Abstract: A quarter-century of statistical research has shown that census coverage surveys, valuable as they are in offering a report card on each decennial census, do not provide usable estimates of geographical differences in coverage. The determining reason is the large number of ``doubly missing'' people missing both from the census enumeration and from coverage survey estimates. Future coverage surveys should be designed to meet achievable goals, foregoing efforts at spatial specificity. One implication is a sample size no more than about $30,000$, setting free resources for controlling processing errors and investing in coverage improvement. Possible integration of coverage measurement with the American Community Survey would have many benefits and should be given careful consideration.

Journal of Studies in Education , 2012, DOI: 10.5296/jse.v2i2.1469
Abstract: Even as we expect an increase in veteran student enrollment in higher education, little attention has been paid to the role students’ background characteristics and college experiences play in college outcomes among student veterans. The purpose of this study is to examine differences in precollege characteristics and college experiences between veteran and nonveteran students and a predictive power of being a veteran student on college outcomes. Using data from the 2008 University of California Undergraduate Experience Survey (UCUES), the study conducted cross tabulations and blocked multiple regression analyses on two college outcomes: college GPA and sense of belonging. Results demonstrate that student veteran status is negatively associated with college GPA. The origins of the negative effect of being a veteran student are discussed.
The Global Seamount Census

Oceanography , 2010,
Abstract: Seamounts are active or extinct undersea volcanoes with heights exceeding ~ 100 m. They represent a small but significant fraction of the volcanic extrusive budget for oceanic seafloor and their distribution gives information about spatial and temporal variations in intraplate volcanic activity. In addition, they sustain important ecological communities, determine habitats for fish, and act as obstacles to currents, thus enhancing tidal energy dissipation and ocean mixing. Mapping the complete global distribution will help constrain models of seamount formation as well as aid in understanding marine habitats and deep ocean circulation. Two approaches have been used to map the global seamount distribution. Depth soundings from single- and multibeam echo sounders can provide the most detailed maps with up to 200-m horizontal resolution. However, soundings from the > 5000 publicly available cruises sample only a small fraction of the ocean floor. Satellite altimetry can detect seamounts taller than ~ 1.5 km and studies using altimetry have produced seamount catalogues holding almost 13,000 seamounts. Based on the size-frequency relationship for larger seamounts, we predict over 100,000 seamounts > 1 km in height remain uncharted, and speculatively 25 million > 100 m in height. Future altimetry missions could improve on resolution and significantly decrease noise levels, allowing for an even larger number of intermediate (1–1.5 km height) seamounts to be detected. Recent retracking of the radar altimeter waveforms to improve the accuracy of the gravity field has resulted in a twofold increase in resolution. Thus, improved analyses of existing altimetry with better calibration from multibeam bathymetry could also increase census estimates.

Abstract: We identify a duplicate pair in the well-known Callahan-Hildebrand-Weeks census of cusped finite-volume hyperbolic 3-manifolds. Specifically, the six-tetrahedron non-orientable manifolds x101 and x103 are homeomorphic.
Notations Around the World: Census and Exploitation  [PDF]
Paul Libbrecht
Computer Science , 2010,
Abstract: Mathematical notations around the world are diverse. Not as much as requiring computing machines' makers to adapt to each culture, but as much as to disorient a person landing on a web-page with a text in mathematics. In order to understand better this diversity, we are building a census of notations: it should allow any content creator or mathematician to grasp which mathematical notation is used in which language and culture. The census is built collaboratively, collected in pages with a given semantic and presenting observations of the widespread notations being used in existing materials by a graphical extract. We contend that our approach should dissipate the fallacies found here and there about the notations in "other cultures" so that a better understanding of the cultures can be realized. The exploitation of the census in the math-bridge project is also presented: this project aims at taking learners "where they are in their math-knowledge" and bring them to a level ready to start engineering studies. The census serves as definitive reference for the transformation elements that generate the rendering of formul{\ae} in web-browsers.

Mathematics , 2015,
Abstract: We call a cusped hyperbolic 3-manifold tetrahedral if it can be decomposed into regular ideal tetrahedra. Following an earlier publication by three of the authors, we give a census of all tetrahedral manifolds and all of their combinatorial tetrahedral tessellations with at most 25 (orientable case) and 21 (non-orientable case) tetrahedra. Our isometry classification uses certified canonical cell decompositions (based on work by Dunfield, Hoffman, Licata) and isomorphism signatures (an improvement of dehydration sequences by Burton). The tetrahedral census comes in Regina as well as SnapPy format, and we illustrate its features.
