Paradoxes Of Democratisation: Environmental Politics In East Asia, Mary Alice Haddad
Paradoxes Of Democratisation: Environmental Politics In East Asia, Mary Alice Haddad
Mary Alice Haddad
This chapter examines environmental politics in four polities that run the full spectrum of political regimes: mainland China (authoritarian), South Korea and Taiwan (newly democratic), and Japan (mature democracy). The chapter argues that variation in environmental politics in each place resulted primarily from the timing of their environmental movements, with subsequent movements learning from predecessors and gaining increasing access to global NGO networks. Paradoxically, when environmental movements became linked to democratization movements (in South Korea and Taiwan), they also became linked to political parties, which hindered access to government policymaking when non-allied parties were in power.
Investigating The Impact Of Restricted Irrigation Practices On Soil Moisture Variability And Distribution In A Dry Farmed Vineyard Site, Boise, Idaho, J. Duffin, David Wilkins, J. Guenther
Investigating The Impact Of Restricted Irrigation Practices On Soil Moisture Variability And Distribution In A Dry Farmed Vineyard Site, Boise, Idaho, J. Duffin, David Wilkins, J. Guenther
David E. Wilkins
Changing climate in semiarid regions may result in increased water stresses for agricultural production as timing and form of precipitation may result in diminished surface water for irrigation. To prepare for these changing conditions, studies are being conducted on the possibility of dry farmed agriculture as an alternative to irrigated production. This study specifically investigates the ability to grow productive wine grapes with limited or zero irrigation in the Boise Front Foothills, West Foothills TIC Vineyard, located in a climate zone receiving less than 300 mm of annual precipitation. Traditional vineyard performance factors such as planting densities, soil type, rootstock, …
Sophomore Field Experiences As An Introduction To The Nature Of Geosciences: Data Collection And Analysis Using Dendrochronology, David Wilkins, M. Kunkel
Sophomore Field Experiences As An Introduction To The Nature Of Geosciences: Data Collection And Analysis Using Dendrochronology, David Wilkins, M. Kunkel
David E. Wilkins
Opportunities for field experiences are often presented as a primary reason that undergraduate students gravitate towards geosciences as a major field of study. What those students may not understand is that, for professional geoscientists, field experiences go beyond the freshman-level field trip, and students may overlook the processes of observation, data collection and analysis that are inherent to the science. The Department of Geosciences at Boise State has developed a set of sophomore field experience courses designed to "set the hook" into new majors and prepare them for field experiences in upper division coursework. These sophomore courses have been shown …

Beginning in 1971 with the first plantings of wine grapes, the wine and wine grape industry in southwest Idaho have grown to become significant contributors to the state economy with an annual impact of $75 million (Bierle et al., 2008). With around 1600 acres under cultivation in 50 vineyards producing at least 24 varietals (as of 2007), wine grapes are the state's second largest fruit crop in acreage, with the majority of the crop (USDA, 2008) being produced in the western Snake River Plain of southwestern Idaho and eastern Oregon. In April, 2007, a 21,400 sq. km area in this …

Disaster Vulnerability And Evacuation Readiness: Coastal Mobile Home Residents In Florida, Margarethe Kusenbach, Jason Simms, Graham Tobin
Disaster Vulnerability And Evacuation Readiness: Coastal Mobile Home Residents In Florida, Margarethe Kusenbach, Jason Simms, Graham Tobin
Jason L Simms
This article examines disaster preparedness in a highly vulnerable population, mobile home park residents in hurricane-prone areas. The vulnerabilities of this population mandate evacuation as the only viable disaster response strategy, but this does not always happen. In order to explore evacuation decision making, interviews were conducted with 75 mobile home park residents in Ruskin, Florida. Descriptive results build on a conceptualization of physical, structural, socio-economic, and ‘‘residual’’ disaster vulner- ability; the latter is defined as a combination of experiences, perceptions, and preparations that inhibit the willingness and abilities of respondents to protect themselves. While residents generally prepared for disasters, …

A Microwave Digestion Method For The Extraction Of Phytoliths From Herbarium Specimens, Jeffrey Parr, V Dolic, Graham Lancaster, William Boyd
A Microwave Digestion Method For The Extraction Of Phytoliths From Herbarium Specimens, Jeffrey Parr, V Dolic, Graham Lancaster, William Boyd
Jeffrey Parr
The extraction of phytoliths from herbarium and/or fresh plant material to obtain a suite of comparative reference samples is an essential component of palaeobotanical studies for the accurate interpretation of fossil phytolith assemblages. A number of established methods have been employed to extract phytoliths from plant material including dry ashing and acid digestion. However, while these methods produce good results, they can be time consuming and have the potential to produce results with some cross-contamination if not monitored closely. In this study, we trial an alternative method using microwave digestion, and compare the results to those produced using a conventional …
A Comparative Analysis Of Wet And Dry Ashing Techniques For The Extraction Of Phytoliths From Plant Material, Jeffrey Parr, Carol Lentfer, William Boyd
A Comparative Analysis Of Wet And Dry Ashing Techniques For The Extraction Of Phytoliths From Plant Material, Jeffrey Parr, Carol Lentfer, William Boyd
Jeffrey Parr
Two methods are commonly used for the extraction of phytoliths from plant material to be used as reference in the analysis of archaeological phytolith samples: (1) spodograms or dry ashings; and (2) acid digestions or wet ashing. It has been suggested that these techniques may modify the resultant samples in different ways. Dry ashing, in particular, has been implicated as a cause of shrinkage and warping in phytolith assemblages when incineration occurs at ≥450°C. The results of a morphometric comparative analysis between the dry ashing and wet ashing methods do not support these claims. This study establishes that differences in …
Land Cover Classification And Economic Assessment Of Citrus Groves Using Remote Sensing, Jennifer Gebelein
Land Cover Classification And Economic Assessment Of Citrus Groves Using Remote Sensing, Jennifer Gebelein
Jennifer Gebelein
The citrus industry has the second largest impact on Florida's economy, following tourism. Estimation of citrus area coverage and annual forecasts of Florida's citrus production are currently dependent on labor-intensive interpretation of aerial photographs. Remotely sensed data from satellites has been widely applied in agricultural yield estimation and cropland management. Satellite data can potentially be obtained throughout the year, making it especially suitable for the detection of land cover change in agriculture and ...

Physical Properties Of Selected Soils By Erosion Class, Alice Jones, Bill Lowery, James Swan, Tom Schumacher
Alice Jones
The effects of soil erosion on soil fertility and yield have been documented with data as early as the 1900s, but there is limited literature relating soil erosion and soil physical properties. A regional research project (NC-174) was established in 1984 to elucidate the effects of erosion on soil productivity, with respect to changes in soil physical properties, and to determine the potential for using computer models to simulate this effect. Data are presented from 15 soils (sites) located in eight states in the North Central United States. Based on the thickness of topsoil, two to three levels of prior …
