Site Assessment For Environmental Restoration, David A. Bainbridge Jan 2013

Site Assessment For Environmental Restoration, David A. Bainbridge

David A Bainbridge

Restoring degraded desert ecosystems is challenging but it can be done. The first key step is understanding the site history and understanding the disturbance and current site conditions. With this information the appropriate steps can be taken to improve the site ecosystem function and structure.

Interactions Between Pieris Oleracea And Pieris Rapae (Lepidoptera: Pieridae) Butterflies, And The Biological Control Agents Cotesia Glomerata And Cotesia Rubecula (Hymenoptera: Braconidae)., Megan V. Herlihy Dec 2012

Interactions Between Pieris Oleracea And Pieris Rapae (Lepidoptera: Pieridae) Butterflies, And The Biological Control Agents Cotesia Glomerata And Cotesia Rubecula (Hymenoptera: Braconidae)., Megan V. Herlihy

Megan V Herlihy

Pieris oleracea, formerly Pieris napi, was once a widespread pierid butterfly in New England until the introduction of a biological control agent, Cotesia glomerata. It has been suggested that C. glomerata is responsible for the range reduction of P. oleracea. There are been several introductions of a second more specialized biological control agent, Cotesia rubecula, to the United States since the 1960’s. My first goal was to determine the current distribution and status of P. rapae parasitoids and the effectiveness of C. rubecula as a biological control agent since its release. The findings of a survey I conducted of the …

Straw Bale Building, David A. Bainbridge Jan 2012

Straw Bale Building, David A. Bainbridge

David A Bainbridge

Straw bale building offers many advantages, high insulation value, thermal mass of interior plaster, resistance to fire, and low embodied resource cost. Super-insulation becomes possible at affordable prices with straw bales. Used with great success for both residential and commercial building projects.


True Cost Accounting For A Post-Autistic Economy, David A. Bainbridge Jan 2012

True Cost Accounting For A Post-Autistic Economy, David A. Bainbridge

David A Bainbridge

True cost accounting attempts to include the full cost of products and services in economic consideration. This brings what are often categorized as "external costs" into pricing. The failure to include these social and environmental costs has led to many of our worst crises -- from global climate change to ill health and resource depletion.

Rebound In Us Productive Sectors, Harry D. Saunders Jun 2011

Rebound In Us Productive Sectors, Harry D. Saunders

Harry D. Saunders

This presentation describes rebound measurements in the US economy, the dominance of "embedded energy" (production-side energy use), and the economic costs of polices to mitigate rebound effects.


Passive Solar Design, David A. Bainbridge Jan 2011

Passive Solar Design, David A. Bainbridge

David A Bainbridge

Passive solar architecture can provide heating, cooling, ventilation and daylighting by using the sun and microclimate resources. Building energy consumption can be cut 80-90% at no increase in building cost by using integrated design principles.

An Entrepreneurial Approach To Librarianship, Flora G. Shrode, Jennifer R. Duncan, Wendy Holliday Apr 2010

An Entrepreneurial Approach To Librarianship, Flora G. Shrode, Jennifer R. Duncan, Wendy Holliday

Flora Shrode

Librarians from Utah State University explain recent efforts to encourage subject librarians to take a more holistic view of their roles. We are shifting from a traditional emphasis primarily on collection development and refocusing on natural connections between collections, instruction, liaison, and reference service. The poster provides background about Utah State University’s situation and explains our approach to analyzing local needs and culture to inform development of a new organizational structure. We describe our vision of subject librarianship, the process by which we assessed librarians’ ideas and goals for performing as subject librarians, and the actions we are taking to …


Alternative "More Efficient" Irrigation Systems, David A. Bainbridge Jan 2010

Alternative "More Efficient" Irrigation Systems, David A. Bainbridge

David A Bainbridge

Many traditional irrigation systems work well for ecological restoration projects. These demand responsive systems are very water efficient and robust and have proved themselves in the most extreme desert conditions.

Using Libqual+® To Inform Strategic Planning, Bradford Dennis, Barbara J. Cockrell Mar 2007

Using Libqual+® To Inform Strategic Planning, Bradford Dennis, Barbara J. Cockrell

Barbara J Cockrell

Western Michigan University Libraries used qualitative and quantitative analysis of their 2004 LibQual+ data to identify needed improvements in service, information control and library as place dimensions. The LibQual+ data set was sufficiently large to allow SPSS analysis by user groups and by discipline. Interpretation and comparison of the data were facilitated by converting the desired, minimum and perceived values into a more tractable composite score. User comments, that are part of this survey, were analyzed using ATLAS.ti. Through an ongoing process of examination, refinement and interpretation of the available information, goals were defined, objectives developed and actions were instigated …

Soil Treatment For Restoration Projects, David A. Bainbridge Jan 1999

Soil Treatment For Restoration Projects, David A. Bainbridge

David A Bainbridge

Soil treatment is a critical step in restoration projects. When soil problems are ignored restoration projects fail. Erosion, compaction, limited infiltration and other problems can make a site very different from its historic function and structure. Treatment can be done with equipment or by hand and will greatly improve chances for success.
