Community Science and the Ecological Merits of Backyard Habitat Patches and Adjacent Green-Spaces for Urban Avian Species

In what ways do small-scale urban backyards contribute to local bird abundance and biodiversity? In what ways might these yards serve as an ‘extension’ of neighboring native forest areas? This project investigates the contribution that a group of backyards, certified through the Backyard Habitat Certification Program, have in the suburb of Hillsdale, Oregon, which is adjacent to the natural area of Keller Woodland. Backyard owners functioning as citizen or community scientists assisted with conducting residential bird point-counts once a week in each backyard and the natural area. Counts were done for a total of 8 weeks during nesting season to better understand how backyard habitat restoration might affect their habitat especially when in close proximity to a natural area. The goal of the project was to help better understand the beneficial effects of urban gardening using native plants and diverse vegetation structure as this relates to bird species richness, and to explore the importance of community scientist contributions. Although the sample size was small, no significant trends were found, but the involvement of community scientists indicated increased skill, depth of understanding, and increased motivation for all participating backyard habitat owners. More backyards are needed for future research and extension into lower-income neighborhoods would be very beneficial to increase awareness of urban habitat connectivity and the diversity seen in backyard environmental characteristics and yard owner backyard habitat knowledge. A larger sample size could reveal correlations and provide a greater significance in data findings for bird abundance and diversity. A logical extension of this project would be to investigate food-web effects, specifically avian prey species, and smaller green-spaces that are often present in urban neighborhoods in addition to the large green-spaces

Ancient oceans and Martian paleohydrology

The global model of ocean formation on Mars is discussed. The studies of impact crater densities on certain Martian landforms show that late in Martian history there could have been coincident formation of: (1) glacial features in the Southern Hemisphere; (2) ponded water and related ice features in the northern plains; (3) fluvial runoff on Martian uplands; and (4) active ice-related mass-movement. This model of transient ocean formation ties these diverse observations together in a long-term cyclic scheme of global planetary operation

Basement and Regional Structure Along Strike of the Queen Charlotte Fault in the Context of Modern and Historical Earthquake Ruptures

The Queen Charlotte fault (QCF) is a dextral transform system located offshore of southeastern Alaska and western Canada, accommodating similar to 4.4 cm/yr of relative motion between the Pacific and North American plates. Oblique convergence along the fault increases southward, and how this convergence is accommodated is still debated. Using seismic reflection data, we interpret offshore basement structure, faulting, and stratigraphy to provide a geological context for two recent earthquakes, an M-w 7.5 strike-slip event near Craig, Alaska, and an M-w 7.8 thrust event near Haida Gwaii, Canada. We map downwarped Pacific oceanic crust near 54 degrees N, between the two rupture zones. Observed downwarping decreases north and south of 54 degrees N, parallel to the strike of the QCF. Bending of the Pacific plate here may have initiated with increased convergence rates due to a plate motion change at similar to 6 Ma. Tectonic reconstruction implies convergence-driven Pacific plate flexure, beginning at 6 Ma south of a 10 degrees bend the QCF (which is currently at 53.2 degrees N) and lasting until the plate translated past the bend by similar to 2 Ma. Normal-faulted approximately late Miocene sediment above the deep flexural depression at 54 degrees N, topped by relatively undeformed Pleistocene and younger sediment, supports this model. Aftershocks of the Haida Gwaii event indicate a normal-faulting stress regime, suggesting present-day plate flexure and underthrusting, which is also consistent with reconstruction of past conditions. We thus favor a Pacific plate underthrusting model to initiate flexure and accommodation space for sediment loading. In addition, mapped structures indicate two possible fault segment boundaries along the QCF at 53.2 degrees N and at 56 degrees N.USGS Earthquake Hazards External Grants ProgramNational Earthquake Hazards Reduction ProgramUTIG Ewing/Worzel FellowshipInstitute for Geophysic

Eastern New Mexico Rural Water System (Ute Pipeline Project)

The Ute Pipeline Project (Project), officially known as the Eastern New Mexico Rural Water System (ENMRWS),is a 151-mile-long pipeline project to provide a sustainable municipal and industrial water supply for several eastern New Mexico communities and a military base. The Congress authorized major federal funding for the Ute Pipeline in the Omnibus Public Land Management Act of 2009. This important milestone for the project was reached after about 45 years of effort.Attention now shifts to myriad details involved in actually constructing, financing,and administering the project

The role of law and ethics in developing business management as a profession

Currently, business management is far from being recognised as a profession. This paper suggests that a professional spirit should be developed which could function as a filter of commercial reasoning. Broadly, management will not be organised within the framework of a well-established profession unless formal knowledge, licensing, professional autonomy and professional codes of conduct are developed sufficiently. In developing business management as a profession, law may play a key role. Where the idea is that business management should be more professsionalised, managers must show that they are willing to adopt ethical values, while arriving at business decisions. The paper argues that ethics cannot survive without legal regulation, which, in turn, will not be supported by law unless lawyers can find alternative solutions to the large mechanisms of the official society, secured by the monopolised coercion of the nation state. From a micro perspective of law and business ethics, communities can be developed with their own conventions, rules and standards that are generated and sanctioned within the boundaries of the communities themselves

Librarians as Partners: Moving from Research Supporters to Research Partners

Academic libraries have long been discussing the need to remain relevant and demonstrate value to their institutions. This paper explores how academic libraries can expand the concept of embedded librarianship to create research partnerships at universities. Such partnerships will enhance value to the institutional research output, as well as increase the visibility of unique librarian skills and library resources. Using a case study from a public research I university, the author discusses innovative roles for librarians on research teams. Embedding academic librarians fully into the research enterprise recognizes the significant contributions that librarians can make as research partners.National Institute on Disability and Rehabilitation Researc

ECORD geophysical and geotechnical hazard site survey offshore Yucatan, Mexico : cruise 2013/4_ECORD

This report provides information on the University of Texas, Institute for Geophysics (UTIG) led ECORD (European Consortium for Ocean Research Drilling) geophysical and geotechnical hazard site survey offshore Yucatan aboard the R/V Justo Sierra which took place from the 16th April to the 23rd April 2013 over a study area within the Chixculub impact crater. The cruise has been carried out under contract for ECORD comprising the acquisition of geophysical data (surface tow boomer, side scan sonar, multibeam echosounder, magnetometer and CHIRP data) and geotechnical data (cone penetrometer tests (CPT)), ahead of scheduled ECORD led drilling of the Chixculub impact crater. The survey was undertaken in joint collaboration between UTIG and Universidad Nacional Autonóma de México (UNAM). Seafloor Geotec, LLC, was commissioned to carry out CPTs at selected sites within the survey area

Major Powers and Militarized Conflict

This article attempts to answer the question of why major powers engage in more active foreign policy behaviors than minor powers. It does so by comparing two explanations for the increased conflict propensity of major powers. The first explanation focuses on major powers’ observable capabilities, while the second stresses their different behavior. We incorporate both into an ultimatum model of conflict in which a state’s cost of conflict consists of both observable and behavioral components. Using data from the period from 1870 to 2001, we empirically illustrate the observable and behavioral differences between major and minor powers. We then utilize a decomposition model to assess the relative significance of the two explanations. The results suggest that most of the difference in conflict propensity between major and minor powers can be attributed to observable differences

Double-beta decay Q values of 130Te, 128Te, and 120Te

The double-beta decay Q values of 130Te, 128Te, and 120Te have been determined from parent-daughter mass differences measured with the Canadian Penning Trap mass spectrometer. The 132Xe-129Xe mass difference, which is precisely known, was also determined to confirm the accuracy of these results. The 130Te Q value was found to be 2527.01(32) keV which is 3.3 keV lower than the 2003 Atomic Mass Evaluation recommended value, but in agreement with the most precise previous measurement. The uncertainty has been reduced by a factor of 6 and is now significantly smaller than the resolution achieved or foreseen in experimental searches for neutrinoless double-beta decay. The 128Te and 120Te Q values were found to be 865.87(131) keV and 1714.81(125) keV, respectively. For 120Te, this reduction in uncertainty of nearly a factor of 8 opens up the possibility of using this isotope for sensitive searches for neutrinoless double-electron capture and electron capture with positron emission.Comment: 5 pages, 2 figures, submitted to Physical Review Letter
