An Economic Valuation of South Dakota Wetlands As A Recreation Resource for Resident Hunters

In spite of efforts to conserve wetlands, intensified agriculture, water projects, and urban development annually diminish the quantity and quality of wetland resources (Weller 1981). Leitch and Danielson (1979) noted that when the discounted value of the returns to drainage exceed drainage costs there is an economic incentive to drain. If present drainage rates continue, Weller (1981) estimated that most wetlands will disappear by the year 2140. Research has only recently focused attention on the need to estimate the public value of wetland benefits and the social costs of drainage (Leitch and Danielson 1979). The disparity between private and social benefits of wetlands has intensified public concern over the extent of wetland drainage (Leitch and Danielson 1979). Matson (1964) reported that a lack of information concerning wetland social benefits has made it difficult to provide a solid foundation for wetland policy decisions. Economic valuations of wetlands are based on the recognition that wetlands yield a flow of services valuable to society (Shabman and Batie 1981). Services or benefits are either indirect (e.g. flood protection) or direct (e. g. production of wildlife and recreation opportunities). The benefits of wetlands as a recreational resource are well documented in the literature (Hammack and Brown 1974, Jaworski and Raphael 1978, Horwitz 1979). This study is concerned with public and private wetlands in South Dakota and the population of hunters that utilize them. Characteristics of importance include; number of resource users, geographic relationship between user populations and the resource, the quantity and quality of the resource, and resource ownership (Hammack and Brown 1974, Thibodeau and Ostro 1981, Palm and Malvestuto 1983). The objective was to estimate the direct economic benefits of South Dakota wetlands as a recreation resource for resident hunters

Randomized comparisons among health informatics students identify hypertutorial features as improving web-based instruction.

Hypertutorials optimize five features - presentation, learner control, practice, feedback, and elaborative learning resources. Previous research showed graduate students significantly and overwhelmingly preferred Web-based hypertutorials to conventional Book-on-the-Web statistics or research design lessons. The current report shows that the source of hypertutorials\u27 superiority in student evaluations of instruction lies in their hypertutorial features. Randomized comparisons between the two methodologies were conducted in two successive iterations of a graduate level health informatics research design and evaluation course. The two versions contained the same text and graphics, but differed in the presence or absence of hypertutorial features: Elaborative learning resources, practice, feedback, and amount of learner control. Students gave high evaluations to both Web-based methodologies, but consistently rated the hypertutorial lessons as superior. Significant differences localized in the hypertutorial subscale that measured student responses to hypertutorial features

ECONOMIC IMPACTS OF THE COLLEGE OF VETERINARY MEDICINE

This report presents methods for evaluating a veterinary college and applies them to the Virginia-Maryland Regional College of Veterinary Medicine. Short-run impacts on income and employment are assessed as well as the long-run benefits of the research, extension, teaching, and clinical services of the college.Public Economics,

Diverse Cross Functional Student Teams: A Teaching Tool For Enhanced Learning

Traditional engineering and science teaching methodology has been to train like-minded students within the discipline of their respective majors. Curriculum time constraints, however, limit the number and nature of out of discipline elective courses. As a result, students are well trained within their respective fields of study but lack the breadth of experience in interacting with other diverse disciplines. Industry, particularly technology-based companies, has observed that solutions to problems have a greater probability of success when all interested parties (purchasing, innovation, marketing, sales, manufacturing, etc.) have input in developing a plan to achieve a desired corporate outcome. It is through this collective action of diverse disciplines that unique solutions are conceived. Many times breakthroughs in innovation and product development occur not through the actions of companies in direct competition but through new entrant companies by modifying technology currently residing in different markets and applications. The breakthrough occurs because the new entrants are not bound by the technology paradigms constraining innovation in their particular market arena. Our goal is to take the diversity lessons gleaned from industry and incorporate them into coursework that creates diverse cross-functional teams such that students learn the benefits of cross-discipline diversity. The College of Business and Technology at ETSU is itself a diverse blend of disciplines (Engineering Technology, Entrepreneurship, Human Nutrition, Marketing, Digital Media, etc) and several graduate and undergraduate courses residing in different departments within the college have intentional programs that encourage cross-discipline enrollment. This action is further facilitated through dual course listings between departments for the same course. Examples of diverse discipline teams will be discussed with attention to outcomes and challenges. Through this diverse cooperative program, students from the technology, business, applied human sciences and digital media disciplines gain a perspective for each other’s expertise and learn to develop teams with diverse skills to meet the increasing challenges for managing business and technology

Spatial Ecology of the Coachwhip, Masticophis flagellum (Squamata: Colubridae), in Eastern Texas

We radio-tracked nine Masticophis flagellum (Coachwhips) to determine home range, habitat use, and movements in eastern Texas from April to October 2000. Home ranges of Coachwhips contained more oak savanna macrohabitat than early-successional pine plantation or forested seep, based on the availability of these three macrohabitats in the study area. Likewise, within their individual home ranges, Coachwhips used oak savanna more than the other two macrohabitats, based on availability. An analysis of microhabitat use revealed that, relative to random sites within their home range, Coachwhips were found at sites with fewer pine trees and more herbaceous vegetation taller than 30 cm. Results of the two analyses, macrohabitat and microhabitat, were consistent: oak savannas contained relatively few pine trees but much herbaceous vegetation taller than 30 cm. Coachwhips made frequent long-distance moves, which resulted in large home ranges. Core activity areas, however, were small. These core activity areas were always within the oak savanna macrohabitat. Long movements, large home ranges, and small core activity areas likely were a result of the preferred oak savanna macrohabitat being patchily distributed in the landscape

Dietary patterns for adults with chronic kidney disease

This is the protocol for a review and there is no abstract. The objectives are as follows: This review will evaluate the benefits and harms of dietary patterns among adults with CKD (any stage including people with end-stage kidney disease (ESKD) treated with dialysis, transplantation or supportive care)

Dietary interventions for adults with chronic kidney disease

Background: Dietary changes are routinely recommended in people with chronic kidney disease (CKD) on the basis of randomised evidence in the general population and non-randomised studies in CKD that suggest certain healthy eating patterns may prevent cardiovascular events and lower mortality. People who have kidney disease have prioritised dietary modifications as an important treatment uncertainty. Objectives: This review evaluated the benefits and harms of dietary interventions among adults with CKD including people with end-stage kidney disease (ESKD) treated with dialysis or kidney transplantation. Search methods: We searched the Cochrane Kidney and Transplant Specialised Register (up to 31 January 2017) through contact with the Information Specialist using search terms relevant to this review. Studies contained in the Specialised Register are identified through search strategies specifically designed for CENTRAL, MEDLINE, and EMBASE; handsearching conference proceedings; and searching the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. Selection criteria: Randomised controlled trials (RCTs) or quasi-randomised RCTs of dietary interventions versus other dietary interventions, lifestyle advice, or standard care assessing mortality, cardiovascular events, health-related quality of life, and biochemical, anthropomorphic, and nutritional outcomes among people with CKD. Data collection and analysis: Two authors independently screened studies for inclusion and extracted data. Results were summarised as risk ratios (RR) for dichotomous outcomes or mean differences (MD) or standardised MD (SMD) for continuous outcomes, with 95% confidence intervals (CI) or in descriptive format when meta-analysis was not possible. Confidence in the evidence was assessed using GRADE. Main results: We included 17 studies involving 1639 people with CKD. Three studies enrolled 341 people treated with dialysis, four studies enrolled 168 kidney transplant recipients, and 10 studies enrolled 1130 people with CKD stages 1 to 5. Eleven studies (900 people) evaluated dietary counselling with or without lifestyle advice and six evaluated dietary patterns (739 people), including one study (191 people) of a carbohydrate-restricted low-iron, polyphenol enriched diet, two studies (181 people) of increased fruit and vegetable intake, two studies (355 people) of a Mediterranean diet and one study (12 people) of a high protein/low carbohydrate diet. Risks of bias in the included studies were generally high or unclear, lowering confidence in the results. Participants were followed up for a median of 12 months (range 1 to 46.8 months). Studies were not designed to examine all-cause mortality or cardiovascular events. In very-low quality evidence, dietary interventions had uncertain effects on all-cause mortality or ESKD. In absolute terms, dietary interventions may prevent one person in every 3000 treated for one year avoiding ESKD, although the certainty in this effect was very low. Across all 17 studies, outcome data for cardiovascular events were sparse. Dietary interventions in low quality evidence were associated with a higher health-related quality of life (2 studies, 119 people: MD in SF-36 score 11.46, 95% CI 7.73 to 15.18; I = 0%). Adverse events were generally not reported. Dietary interventions lowered systolic blood pressure (3 studies, 167 people: MD -9.26 mm Hg, 95% CI -13.48 to -5.04; I = 80%) and diastolic blood pressure (2 studies, 95 people: MD -8.95, 95% CI -10.69 to -7.21; I = 0%) compared to a control diet. Dietary interventions were associated with a higher estimated glomerular filtration rate (eGFR) (5 studies, 219 people: SMD 1.08; 95% CI 0.26 to 1.97; I = 88%) and serum albumin levels (6 studies, 541 people: MD 0.16 g/dL, 95% CI 0.07 to 0.24; I = 26%). A Mediterranean diet lowered serum LDL cholesterol levels (1 study, 40 people: MD -1.00 mmol/L, 95% CI -1.56 to -0.44). Authors' conclusions: Dietary interventions have uncertain effects on mortality, cardiovascular events and ESKD among people with CKD as these outcomes were rarely measured or reported. Dietary interventions may increase health-related quality of life, eGFR, and serum albumin, and lower blood pressure and serum cholesterol levels. Based on stakeholder prioritisation of dietary research in the setting of CKD and preliminary evidence of beneficial effects on risks factors for clinical outcomes, large-scale pragmatic RCTs to test the effects of dietary interventions on patient outcomes are required
