Intellectual property (IP) management: organizational processes and structures, and the role of IP donations

Journal Articles & Books
Diciembre, 2008

This paper examines intellectual property (IP) management in U.S. companies and addresses three questions: What are typical sources of IP? How do companies manage IP? What role do donations of IP play in IP management? We used in-depth interviews and an on-line survey to gather data. We found that firms develop their IP position from a wide variety of sources such as joint ventures, acquisitions, and consulting contracts, but internal development is still the primary source of IP.

Within the United Nations Framework Convention on Climate Change (UNFCCC) Kyoto Protocol, countries have significant latitude to define a forest. The most important parameter affecting area designated as forest is the minimum crown cover which can be set between 10 and 30%. The choice will have implications for the amount of land available in a country for afforestation and reforestation activities within the Clean Development Mechanism (CDM-AR). In this paper, we present an analysis of the regional differences in land availability for CDM-AR projects.

Satellite detection of land-use change and effects on regional forest aboveground biomass estimates

Journal Articles & Books
Diciembre, 2008

We used remote-sensing-driven models to detect land-cover change effects on forest aboveground biomass (AGB) density (Mg·ha⁻¹, dry weight) and total AGB (Tg) in Minnesota, Wisconsin, and Michigan USA, between the years 1992-2001, and conducted an evaluation of the approach.

Mapping and assessing spatial multiscale variations of birds associated with urban environments in metropolitan Taipei, Taiwan

Environmental change can be monitored and assessed by analyzing changes in bird populations. This study employed multivariate factorial kriging (MFK) to determine the multiscale changes in the distribution of five commonly observed bird species to urban environmental change. Areas of metropolitan Taipei were analyzed to determine the extent and effect of land cover. A digital elevation model and normalized difference vegetation index were also constructed. Spatial patterns of variation in bird populations were analyzed by MFK at a regional scale (16 km) and local scale (2 km).

Impacts of climate warming on vegetation in Qaidam Area from 1990 to 2003

Journal Articles & Books
Diciembre, 2008

The observed warming trend in the Qaidam area, an arid basin surrounded by high mountains, has caused land surface dynamics that are detectable using remotely sensed data. In this paper, we detected land-cover changes in the Qaidam Area between 1990 and 2003 in attempt to depict its spatial variability. The land-cover changes were categorized into two trends: degradation and amelioration, and their spatial patterns were examined. Then we estimated the correlation coefficients between growing-season NDVI and several climatic factors with the consideration of duration and lagging effects.
