A Comparison Of Teacher-Directed Versus Self-Directed Learning Preferences Of Students At Five Selected Community Colleges: Exploring The Relationships Among Age, Gender, And Academic Majors, Huiming Wang
Electronic Theses and Dissertations
One of the major priorities for community colleges is to focus on the pedagogical tools that will allow students to achieve excellence and quality in curriculum and instruction to meet the changing societal needs (Shearon & Tollefson, 1989). Rapid demographic, social, and technological changes demand that community colleges produce self-directed lifelong learners (Closson, 1996). The study of student learning preferences for more teacher-directed or more self-directed learning is one of the concepts that is important in enhancing teaching and learning practices. The purpose of this study was to examine students' teacher-directed versus self-directed learning preferences in specific courses. The possible …
Pest Management Strategies For Longhorn Army Ammunition Plant And An Assessment Of Aerial Radiography For Hazard Rating Pine Stands For Southern Pine Beetle Infestation, James Matthews
Electronic Theses and Dissertations
Currently, sampling or hazard rating insects at military installations is limited. The use of aerial videography is a relatively new technology and is currently used for aerial surveys and is being developed for hazard rating for southern pine beetle. The purpose of this study was to apply existing sampling methods for various insects and disease at the Longhorn Army Ammunition Plant in Karnak, Texas and to test the effectiveness of aerial videography for hazard rating pine stands for southern pine beetle. Based on field data, stands were generally rated as moderate for southern pine beetle; moderate to high infestations of …

Owls Of The Idaho National Engineering And Environmental Laboratory (Ineel), Natalie A. Fahler
Electronic Theses and Dissertations
The Idaho National Engineering and Environmental Laboratory (INEEL) is a 2,315 km2 energy research and development site located on the Upper Snake River Plain of Southeast Idaho. Owl research was conducted on the site during the spring and summers of 1996-1997. Objectives were to: a) determine productivity, habitat use, and possible nest site selection factors of burrowing owls (Athene cunicularia ), b) verify the presence of small owl species including the boreal owl (Aegolius funereus), the northern saw-whet owl (A. acadicus), the western screech owl (Otus kennicottii), the flammulated owl (0. flammeolus), and the northern pygmy owl (Glaucidium gnoma), c) …
Passerine Use Of Grasslands Managed With Two Grazing Regimes On The Missouri Coteau In North Dakota, Natoma A. Schneider
Passerine Use Of Grasslands Managed With Two Grazing Regimes On The Missouri Coteau In North Dakota, Natoma A. Schneider
Electronic Theses and Dissertations
Several rotational grazing systems have been implemented on the Missouri Coteau in central and northcentral North Dakota as part of the Prairie Pothole Joint Venture (PP N). The impacts these systems have on grassland passerines are not fully understood. Objectives for this study include determining relative abundance, species composition and reproductive success of passerines as well as vegetation characteristics for rotational and traditional season-long grazing regimes. Passerine relative abundance and species richness were determined on rotational grazing systems during 1995-1997 and on season-long grazed pastures during 1996-1997 using 122 fixed, 100 m radius, point counts. Relative abundance was assessed by …
Water And Soil Chemistry In Agricultural Wetland Landscapes In The Prairie Pothole Region Of Eastern South Dakota, David E. Kringen
Water And Soil Chemistry In Agricultural Wetland Landscapes In The Prairie Pothole Region Of Eastern South Dakota, David E. Kringen
Electronic Theses and Dissertations
This study investigated the nutrient filtering capability of four seasonal and two semipermanent wetlands in the Prairie Pothole Region of eastern South Dakota. The wetlands were situated in two farming systems near Madison, SD. Wetlands were instrumented with observation wells arranged in two axes extending from the wetland border to upland sites. Nitrate-nitrogen and orthophosphate concentrations from wetland surface water and surrounding groundwater were determined on a two-week cycle throughout the 1994 and 1995 growing season using a Hach DR/2000 spectrophotometer. Results indicated that N03-N concentrations were higher in semipermanent wetlands (8.63 mg L·1) than seasonal wetlands (4.29 mg L" …
The Wind Cave National Park Elk Herd: Home Ranges, Seasonal Movements, And Alternative Control Methods, Peter Bauman
The Wind Cave National Park Elk Herd: Home Ranges, Seasonal Movements, And Alternative Control Methods, Peter Bauman
Electronic Theses and Dissertations
Elk (Cervus elaphus ne/soni) herd organization, movements, and home range size in Wind Cave National Park (WICA) were studied from May 1996 to August 1997. Twenty radiocollared elk ( 10 males, 10 females) were relocated by ground and aerial telemetry. Radiocollared elk were relocated two times/week, resulting in 1,595 relocations ( 410 ground, 1, 185 aerial). Coefficients of association (CA) for radiocollared cows averaged 0.005 during spring/summer 1996, 0.033 during spring/summer 1997, and 0.295 during falVwinter 1996. Coefficients of association for radiocollared bulls averaged 0.011 during spring/summer 1996, 0.015 during spring/summer 1997, and 0.075 during faIVwinter 1996. Three cow subherds …

The Relationship Between Rural Low-Income Women's Knowledge And Short-Term Duration Of Breastfeeding, Jefferey J.A. Enstad
The Relationship Between Rural Low-Income Women's Knowledge And Short-Term Duration Of Breastfeeding, Jefferey J.A. Enstad
Electronic Theses and Dissertations
Although patterns of breastfeeding initiation and duration among American women have made dramatic changes over the past 100 years, these patterns have not been studied in rural, low-income women. Furthermore, even less is known about the characteristics of rural low-income women who practice short-term breastfeeding. Therefore, the problem under investigation was to explore the relationship between rural low-income women's knowledge and short-term duration of breastfeeding. The objectives of the study were to: 1) describe what are the characteristics of rural low-income women who breastfeed for four or more weeks postpartum, 2) describe what sources did they receive breastfeeding instruction and …
Differences In Body Image And Depression Scores In Postmenopausal Women Who Do And Do Not Take Hormone Replacement Therapy, Doreen M. Boomsma
Differences In Body Image And Depression Scores In Postmenopausal Women Who Do And Do Not Take Hormone Replacement Therapy, Doreen M. Boomsma
Electronic Theses and Dissertations
The purpose of this descriptive study was to examine differences in depressive symptomology and perceived body image in postmenopausal women who currently used HRT with women who never used HRT and women who had previously used HRT but were currently not. Few medical treatments presently available for postmenopausal and menopausal women have such substantial benefits, and risks, as hormone replacement therapy (HRT). The study is based on findings that document the use of HRT in preventing chronic illnesses that afflict elderly women. Chronic illness and disability has been shown to increase the incidence of depression in the general population. Chronic …
Effects Of Temperature, Water Hardness, And Recirculation On Copper Corrosion, Brian R. Weiss
Effects Of Temperature, Water Hardness, And Recirculation On Copper Corrosion, Brian R. Weiss
Electronic Theses and Dissertations
In previous work, the effects of water quality have been shown to influence the formation of scale from copper corrosion. A general understanding of the effects of water quality on copper corrosion have been difficult to obtain because of complex interactions of water quality variables on copper corrosion in different water supply systems. The objective of this study was to examine the effects of temperature and water hardness on copper corrosion occurring in a household water supply system. The effects of recirculation were also studied in concurrence with the above water quality parameters. Electrochemical corrosion testing and corrosion by -product …
