The Influence Of Community Commitment On Knowledge Management In Online Communities Of Practice, James Gregory Greer

Masters Theses & Doctoral Dissertations

Online Communities of Practice allow their members to transcend the limitations of geography when communicating about a topic. However, many communities of practice fail due to a lack of knowledge sharing. How can community leaders build communities of practice that facilitate knowledge sharing and knowledge utilization among their members? One of the driving factors in any group is the commitment that members make to the community. Past research has shown that the continuance, affective and normative commitment of members influences thread-reading, posting and moderating behaviors in online communities. However, online communities of practice may have different dynamics than other online …

Operational Multi-Angle Hyperspectral Sensing For Feature Detection, Charles R. Bostater, Donald K. Brooks

Ocean Engineering and Marine Sciences Faculty Publications

Remote sensing results of land and water surfaces from airborne and satellite platforms are dependent upon the illumination geometry and the sensor viewing geometry. Correction of pushbroom hyperspectral imagery can be achieved using bidirectional reflectance factors (BRF's) image features based upon their multi-angle hyperspectral signatures. Ground validation of features and targets utilize non-imaging sensors such as hemispherical goniometers. In this paper, a new linear translation based hyperspectral imaging goniometer system is described. Imagery and hyperspectral signatures obtained from a rotation stage platform and the new linear non-hemispherical goniometer system shows applications and a multi-angle correction approach for multi-angle hyperspectral pushbroom …

Changes In Soil Carbon Sequestration In Pinus Massoniana Forests Along An Urban-To-Rural Gradient Of Southern China, H. Chen, W. Zhang, Frank S. Gilliam, L. Liu, J. Huang, T. Zhang, W. Wang, J. Mo

Biological Sciences Faculty Research

Urbanization is accelerating globally, causing a variety of environmental changes such as increases in air temperature, precipitation, atmospheric CO₂, and nitrogen (N) deposition. However, the effects of these changes on forest soil carbon (C) sequestration remain largely unclear. Here, we used urban-to-rural environmental gradients in Guangdong Province, southern China, to address the potential effects of these environmental changes on soil C sequestration in Pinus massoniana forests. In contrast to our expectations and earlier observations, soil C content in urban sites was significantly lower than that in suburban and rural sites. Lower soil C pools in urban sites were …

Distel: A Distributed El+ Ontology Classifier, Raghava Mutharaju, Pascal Hitzler, Prabhaker Mateti

Computer Science and Engineering Faculty Publications

OWL 2 EL ontologies are used to model and reason over data from diverse domains such as biomedicine, geography and road traffic. Data in these domains is increasing at a rate quicker than the increase in main memory and computation power of a single machine. Recent efforts in OWL reasoning algorithms lead to the decrease in classification time from several hours to a few seconds even for large ontologies like SNOMED CT. This is especially true for ontologies in the description logic EL⁺ (a fragment of the OWL 2 EL profile). Reasoners such as Pellet, Hermit, ELK etc. make …

Early Humboldtian Influences On Alfred Russel Wallace's Scheme Of Nature [Presented At The Alfred Russel Wallace And His Legacy Royal Society Of London Meeting, 21 October 2013], Charles H. Smith

DLPS Faculty Publications

Alfred Russel Wallace’s 1858 Ternate paper on natural selection is a famous work in the history of science. Beyond his co-discovery of the principle, moreover, Wallace is known for a large number of early applications of the idea, both to biological and biogeographical subjects. Yet how much do we really know about Wallace’s own evolution of thought, and his actual intentions before his views were swallowed up by the inertia of Darwin’s revolution? A number of differences between Wallace’s and Darwin’s views are apparent and have been much treated over the years, but related discussions dwell more on effects than …

Does Residence In An Ethnic Community Help Immigrants In A Recession?, Pengyu Zhu, Cathy Yang Liu, Gary Painter

Urban Studies and Community Development Faculty Publications and Presentations

Research on how the residential segregation of immigrant populations has impacted their labor market outcomes presents many challenges because of the fact that immigrants often choose to locate near co-ethnics to share resources and cultural amenities. Because not all immigrants choose to live in these ethnic communities, identification of a causal effect on living in an ethnic community is problematic. The estimation of the effect of living in these ethnic communities is also difficult because it is ambiguous whether such residence will help or harm the labor market outcomes of immigrants. This study implements a number of approaches to help …

Niche Firms, Mass Markets, And Income Across Countries: Accounting For The Impact Of Entry Costs, Pedro Bento

Economics Faculty Working Papers Series

I develop a model of monopolistic competition in which I distinguish between niche markets and mass markets, in the spirit of Holmes and Stevens (2013). Firms choose between entering a small niche market with high markups or a large mass market with low markups. Entry costs have a much greater impact on output in the niche market as the gains to specialization are high, relative to the mass market where varieties are highly substitutable. Calibrated to match data from U.S. manufacturing, the model generates an elasticity of total factor productivity with respect to entry costs more than twice that in …

Ringtail (Bassariscus Astutus) Noninvasive Survey Methods, Density, And Occupancy In Central New Mexico, Usa, Robert L. Harrison

Western North American Naturalist

I tested 3 hair-collection devices used for population surveys of ringtails (Bassariscus astutus): PVC pipes, modified cage traps, and triangular Coroplast^® tunnels. Coroplast tunnels were the most efficient, with hair obtained by 92% of tunnels tested on radio-collared ringtails. I used the tunnels to survey ringtails on the Sevilleta National Wildlife Refuge in central New Mexico. Probability of detection in areas where ringtails were present was 74% (95% CI 0.56–0.86). Population density was estimated to be 0.17–0.33 ringtails · km^–2 and occupancy (Ψ) by ringtails was 0.56 (95% CI 0.35–0.75).

Tolerance Values And Effects Of Selected Environmental Determinants On Caddisfly (Trichoptera) Distribution In Northwest And North Central Washington, Usa, Dean W. Blinn, David E. Ruiter

Western North American Naturalist

Caddisflies were collected at 181 wall seep, stream, river, and lake habitats in 7 counties in northwest and north central Washington over a 6-year period. From 17,405 specimens, we identified 164 adult caddisfly species within 62 genera and 16 families. Twenty taxa were new state records, bringing the number of species currently reported from Washington to 230. Species assemblages were compared to altitude, physicochemical factors, aquatic habitats, and land use (urban, agriculture, and forest) on the west and east sides of the North Cascade Range. Species richness showed significant positive correlations to altitude and pH and showed significant negative correlations …

Multi-Spatiotemporal Patterns Of Residential Burglary Crimes In Chicago: 2006-2016, Jun Luo

College of Natural and Applied Sciences

This research attempts to explore the patterns of burglary crimes at multi-spatiotemporal scales in Chicago between 2006 and 2016. Two spatial scales are investigated that are census block and police beat area. At each spatial scale, three temporal scales are integrated to make spatiotemporal slices: hourly scale with two-hour time step from 12:00am to the end of the day; daily scale with one-day step from Sunday to Saturday within a week; monthly scale with one-month step from January to December. A total of six types of spatiotemporal slices will be created as the base for the analysis. Burglary crimes are …

Extending The Conversation: Raising Issues Of Rurality In English Teacher Education, Lisa Eckert, Robert Petrone

Faculty Works

Situated within the challenges faced by English teacher educators in the frontier state of Montana, this article argues for the need for increased attention to issues of rurality within the field of English Education. Conceptualizing rural education as an issue of social justice, the article suggests several approaches English teacher educators and researchers might take in thinking about rural English education, including integrating readings related to rurality in English Education coursework, researching the unique challenges of teacher identity formation within rural contexts, and emphasizing research focused on rural youth literacy practices.

E-Bikes In The United States, John Macarthur

PSU Transportation Seminars

Electric bicycles (e-bikes) are well established in China and other Asian and European countries but have yet to realize their potential in the United States, although recently the number of e-bikes has been growing. Research on the economic, operational, and safety issues of e-bikes in the U.S. is limited. This research aims in part to understand if different bicycling technology, in this case electric assist bicycles or e-bikes, can reduce barriers to bicycling and encourage more bike trips and longer bike trips, and increase the diversity of people bicycling, including people with a disability or chronic injury to bicycle. Some …

"Nobody Wants To Eat Them Alive:” Ethical Dilemmas And Dual Media Narratives On Domestic Rabbits As Pets And Commodity, Gayane F. Torosyan, Brian Lowe

Proceedings of the New York State Communication Association

Using semiotic analysis, this study explores changes occurring in the societal perception of rabbits as farm animals as juxtaposed to their increasing popularity as domestic companions. This study is based on a preliminary hypothesis that rabbits are increasingly perceived and portrayed in media as domestic companion animals similar to cats and guinea pigs, which challenges a parallel narrative that views rabbits as commodities for their meat and fur. Operating within a theoretical framework that considers news media as both socially constructed reality and recorded history, the study examines the dynamics of change in numbers of coded news narratives drawn as …

Effect Of Unplanned Urban Growth On Human Health And Sustainable Development: A Spatial Analysis Of The Urban Growth Patterns In Nepal, Keshav Bhattarai

Himalayan Policy Research Conference

This paper first provides a spatial analysis of Nepal’s urban growth patterns from historical perspectives. Second, it geovisualizes urban morphologies of the Kathmandu metropolitan area using ESRI made CityEngine to display how unplanned concrete jungle would not only exert stresses on urban lives through increased heat waves and greenhouse gases, but also from increased urban vulnerabilities. Third, the paper analyzes urban sprawls and their unintended but irreversible environmental consequences on human health and sustainability. Fourth, it develops land use/cover metrics using remote sensing techniques to determine the ratio of built-in structures and open spaces. The ultimate goal of this paper …

Using Indicators Projects As Prompts For Exploring Equity: A Case Study Of Greater Portland Pulse, Meg Merrick, Diane Besser, Shelia A. Martin

Institute of Metropolitan Studies Publications

This paper describes the process that the Greater Portland Pulse (GPP) initiated to incorporate the measurement of progress toward social equity into the project. While equity may appear to be a widely accepted priority for communities, the GPP process created a dialogue that was sometimes contentious but also profoundly educational for the participants revealing some of the complexities, not only of the issue of equity, but the challenges (particularly the inadequacy of available data) and trade-offs that are inescapable when using conventional data sets.

Additionally, this paper discusses some of the consequences of a process that, while incorporating equity values …
