Marketing Margins Of Strawberries 2006-2010 Shipping Point-Terminal-Retail Price, Matej Mikle Barat

Graduate Theses and Dissertations

This thesis examines vertical price relationships for fresh strawberries. Specifically, the focus is on three stages of the vertical chain. The first stage is the shipping point. Shipping points represent major strawberry production regions and are the closest price point to the farm. The second stage is the terminal market. Terminal markets are wholesale markets in major US cities. The third stage is the retail level. Retail level prices are measured as average supermarket prices in the same cities for which terminal market prices are available. Using weekly data, markup equations are estimated from upstream to downstream levels of the …

The Integration Of Technology Within Physical Education Teacher Education: Perceptions Of The Faculty, Helena Baert

Graduate Theses and Dissertations

In 2008, the national Physical Education Teacher Education (PETE) standards included a more integrated approach to teaching pre-service teachers about technology and stated that teacher candidates should be able to plan and implement technology infused learning experiences that meet lesson objectives. With the inclusion of the 2008 standards, PETE faculty have the task to create instruction that effectively integrates technology. This study investigated the preparedness for technology integration of 198 teacher educators within nationally recognized PETE programs. The study utilized survey research design to identify current technologies used, analyze current level of technology proficiency in relationship to the level of …

An Exploratory Analysis Of The Relationship Between Teleconnections And Selected Pollution Parameters, Steve Ray Hardin

All-Inclusive List of Electronic Theses and Dissertations

The relationship between atmospheric circulation patterns, as represented by teleconnection indices, and selected air pollutants was investigated. Correlations were run for levels of three air pollutants: particulate matter less than 10 microns in diameter (PM10), ozone (O3) and sulfur dioxide (SO2); and three atmospheric teleconnection indices: the Multivariate El Niño-Southern Oscillation Index (MEI), the Arctic Oscillation (AO) and the North Atlantic Oscillation (NAO). Pollutant levels were observed at stations in or near 15 North American cities between 1970 and 2004. Significant correlations as strong as .386 were found for selected individual cities and counties when dates were restricted to the …

Iron Limitation Of A Springtime Bacterial And Phytoplankton Community In The Ross Sea: Implications For Vitamin B12 Nutrition, Erin M. Bertrand, Mak A. Saito, Peter A. Lee, Robert B. Dunbar, Peter N. Sedwick, Giacomo R. Ditullio

OES Faculty Publications

The Ross Sea is home to some of the largest phytoplankton blooms in the Southern Ocean. Primary production in this system has previously been shown to be iron limited in the summer and periodically iron and vitamin B-12 colimited. In this study, we examined trace metal limitation of biological activity in the Ross Sea in the austral spring and considered possible implications for vitamin B-12 nutrition. Bottle incubation experiments demonstrated that iron limited phytoplankton growth in the austral spring while B-12, cobalt, and zinc did not. This is the first demonstration of iron limitation in a Phaeocystis antarctica-dominated, early …

Assessing Environmental Conditions At The Friar Tuck Mining Complex, Dugger, Indiana, Windy Jo Mcbride

All-Inclusive List of Electronic Theses and Dissertations

Many abandoned mine lands (AML) continue to present significant environmental concerns. The abandoned Friar Tuck Mining Complex in Greene and Sullivan counties, Indiana, continues to impair local water quality despite closing in 1952 for operations and multiple remediation attempts. Most areas within the Friar Tuck Mining Complex have been successfully remediated; however, the area of research interest requires additional treatment and continues to be impacted by runoff from gob piles. Subsequently, areas characterized by a loss of vegetation where mine seeps occur behave unpredictably and are characterized by the exposure of bare soil. These mine seep areas are of particular …

Assessment And Impact Of Gentrified Public Housing Neighborhoods In The United States: A Case Study Of Chicago, Todd W. Sink

All-Inclusive List of Electronic Theses and Dissertations

Social-mix housing policies play a unique role in shaping the geography of gentrification in cities throughout the U.S. and Europe. The HOPE VI program in the U.S. is one popular example. Since its inception in 1992, HOPE VI has simultaneously displaced thousands of urban poor from their homes and neighborhoods, reduced their housing opportunities, and created and encouraged housing development for a more affluent population. Yet over the years, very few empirical studies have emerged that examine the place-based outcomes of HOPE VI within the context of gentrification. As such, important empirical questions remain unanswered. This study focuses on the …

The Impact Of Shrimp Farming On Mangrove Ecosystems And Local Livelihoods Along The Pacific Coast Of Ecuador, Stuart Edward Hamilton

Dissertations

This manuscript examines the expansion of Ecuador’s shrimp aquaculture industry since 1970 and the implications of this expansion on coastal residents’ food security and livelihood options. Shrimp aquaculture expanded from essentially nothing in 1970; to account for 26% of all Ecuadorian private exports by 1998. The rapid expansion of shrimp aquaculture in Ecuador’s estuaries has caused a fundamental shift in livelihoods among those who live and work in the immediate vicinity of the newly created shrimp farms. This research not only details the important land use change that has occurred within Ecuador’s estuaries during the transition from mangrove estuary to …

The Evaluation Of The Use Of A Paper Tracking Form To Improve Provider Adherence To Lipid Guidelines, Diane Ladd

Graduate Theses, Dissertations, and Problem Reports (ETD)

Heart disease is the leading cause of death in men and women in the United States. Significant research into the risk factors for cardiovascular disease has been done, and the effect of hyperlipidemia on cardiovascular risk has been well documented. Recent research has shown that there is a lack of adherence to lipid guidelines by primary care providers. Failure to follow clinical guidelines for lipid disorders leads to increased cardiovascular morbidity and mortality. The objective of the project was to evaluate whether a simple, paper-based, lipid tracking form could improve provider adherence to current lipid guidelines. This descriptive study used …

Outcrop Lithostratigraphy And Petrophysics Of The Middle Devonian Marcellus Shale In West Virginia And Adjacent States, Margaret E. Walker-Milani

Graduate Theses, Dissertations, and Problem Reports (ETD)

A stratigraphic study of 15 partial outcrops of the Marcellus Shale in West Virginia, Pennsylvania, and Maryland has identified six distinct lithofacies. These include grey calcareous shale (Facies 1), limestone (Facies 2), black calcareous shale (Facies 3), black non-calcareous shale (Facies 4), grey non-calcareous shale (Facies 5) and K-bentonite (Facies 6). Packages of these facies have been organized into six vertically stacked units (A-F). Deposition of the facies resulted from the rise and fall of relative sea level, which in turn shifted the location of the thermocline and affected the amount of terrigenous sediment distributed from the eastern source. Facies …

Modeling Phloem Temperatures Relative To Mountain Pine Beetle Phenology, Matthew Jared Lewis

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

We explore a variety of methods to estimate phloem temperatures from ambient air temperatures suitable for the mountain pine beetle, Dendroctonus ponderosae. A model's ability to induce the same phenology generated from observed phloem temperatures measures its effectiveness rather than a simple reconstruction of phloem temperatures. From a model's phenology results we are able to ascertain whether the model produces a similar amount of developmental energy exhibited by observed phloem temperatures.

Three models performed best: Newton, Newton South and Matching. The Newton model uses Newton's Law of Cooling to effectively estimate northern aspect phloem temperatures. The Newton South model …

In The Crosshairs: Second Amendment Lawyers And Cases In State And Federal Appellate Courts, H. Carl Taylor Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Judicial behavior, the types of activities and behaviors judges become involved with in their capacity on the bench, has a profound and lasting impact on the types of decisions rendered by judges across all courts that comprise the American judiciary (Baum 2000; Baum 2006; Maveety 2002). There is a growing realization that judicial behavior encompasses more than just the making of good laws and public policy decisions (Baum, 2000; Baum 2006; Hammond, Bonneau, & Sheehan 2005; Comparato 2003). For example, Songer & Haire (1992) explore integrated approaches to the study of judicial voting through obscenity cases in the U.S. Courts …

Surplus Value Extraction In Mental Labor In The Teaching Profession, Lindsey D. Felton

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research examines the labor of a public education school teacher and the value that is extracted from their labor. Teachers' working conditions and mental labor are assessed through qualitative research methods to help in explaining the various impacts and perceptions that teachers have within Monongalia and Preston Counties in West Virginia. Interviews and textual analysis research aided in uncovering issues of mental labor, labor exploitation, alienation of labor, and working conditions among teachers. Furthermore, how these issues coincide with the theory of surplus value extraction and the theory of labor alienation within Marxist literature.

Edaphic And Land Use Influences On Central Appalachian Fens, Sarah Deacon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Local and landscape-scale factors influence peatland floristic assemblages. Our goal in this paper was to assess the interactions between wetland vegetation communities, edaphic factors, and surrounding land cover in central Appalachian peatlands. Specifically we quantified plant community dynamics in relation to edaphic factors and land cover and identified species level responses to human altered landscapes. Cluster analysis on vegetation data identified 3 vegetation groups; an emergent floristic assemblage, a shrub dominated group, and a group with mixed shrub and emergent vegetation. We found that wetlands with emergent vegetation cover were more often associated with natural land cover, higher pH and …

Factors Predicting Exercise Behavior Of Graduate Students, Bibha Gautam

Theses and Dissertations

Graduate school is often experienced as a time of increased demands/expectations resulting in heightened levels of stress due to academic work, family responsibilities, job demands, financial pressure, and other life related issues. Besides stress, graduate school also brings about significant physical inactivity due to the shift of the immediate priority to academic accomplishment. Reports of increasing prevalence of cardiovascular disease (CVD) risk factors among students highlight that this group may have particular risk not well-identified. Yet, relative risk can be reduced by lifestyle modifications, such as eating well, exercising, and stress reduction. The majority of the risk factors, to a …

Bowen Family Systems Theory And Its Relationship To Teachers: Does Differentiation Of Self Predict Teacher Job Satisfaction?, Noal Baxter Cochran

Dissertations

Educational leaders are charged with maintaining the academic success of students, the faith of stakeholders in the educational process, and the growth of the educational profession. These objectives have become difficult during a time of noticeable discontent among the stakeholders of educational systems. The discontent is noted strongly among the ranks of teachers who continue to cite decreased job satisfaction as they face increased internal and external accountability pressures, declining resource availability, and reduced familial support. The resulting teacher job dissatisfaction has led to an increased need among the leadership of educational systems to develop an understanding of the issues …

Integrating Distributed Work: Task Design, Communication And Tacit Coordination Mechanisms, Kannan Srikanth, Phanish Puranam

Research Collection Lee Kong Chian School Of Business

We investigate coordination strategies in the remote delivery of business services (i.e. Business Process Offshoring). We analyze 126 surveys of offshored processes to understand both the sources of difficulty in the remote delivery of services as well as how organizations overcome these difficulties. We find that interdependence between offshored and onshore processes can lower offshore process performance. Investment in coordination mechanisms such as modularity, ongoing communication and generating common ground across locations ameliorate the performance impact of interdependence. In particular, we are able to show that building common ground - knowledge that is shared and known to be shared - …

Temporal And Spatial Variability Of Phytoplankton Biomass In Coastal Mississippi Waters, Lorin Matthew Dornback

Master's Theses

Chlorophyll concentrations were measured in western Mississippi coastal waters to determine the spatial and temporal variability of phytoplankton. Nutrients (nitrate, silicate, phosphate), river discharge, temperature, salinity, stratification, tides, currents and winds were measured in concert with the phytoplankton concentrations. The purpose of this study was to determine the seasonal variability in phytoplankton and what was driving the variability. This study was comprised of a three year (September 2007-November 2010) time series where samples were taken once a month for eight stations. Profiles of each station were taken using a Conductivity, Temperature and Depth (CTD) sensor and a WET Labs FL-3 …

The Use Of Remote Sensing For Mapping Possible Vectors Of West Nile Virus In Mississippi, Brian Matthew Moore

Master's Theses

There is renewed interest in disease surveillance due to the persistence of numerous vector-borne diseases. Though the life-history processes of disease vectors are known to dictate their distribution patterns, it has been hypothesized that vectors, such as local mosquito abundance, could be predicted from factors such as climate and land use/land cover. Remote sensing has been used as a supplement to traditional methods of mosquito surveillance and to map the spatial distribution of mosquito habitats. This, in turn, affords optimism for improved vector/disease management to identify the best use of remote sensing data and geo-statistical techniques to predict and map …

Use Of The School Resource Centre Among Malaysian High School Teachers, Yushiana Mansor, Norhiyah Mohd Nor

Library Philosophy and Practice (e-journal)

This study investigates the pattern of School Resource Centre (SRC) use among teachers from selected high schools in Malaysia. Survey methodology was used and questionnaire was the only instrument used to gather relevant information for the study. The findings of the study indicated that the level of SRC usage among teachers is still low. While only a small number of teachers really used SRC services for their teaching-learning purposes. In general, the study seems to suggest that there was an overall lack of interest in the use of SRC by teachers. The findings further revealed the factors that might have …

Diversification Economies And Efficiencies In A ‘Blue-Green Revolution’ Combination: A Case Study Of Prawn-Carp-Rice Farming In The ‘Gher’ System In Bangladesh, S Rahman, Bk Barmon, N Ahmed

School of Geography, Earth and Environmental Sciences

Gher' farming is a unique system that incorporates the joint operation of three enterprises: freshwater prawn, fish and HYV rice and is expanding rapidly in the coastal regions of Bangladesh. In this paper we evaluate the performance of this unique system in terms of the existence of diversification economies (amongst the three integrated enterprises), scale economies and technical efficiency using a stochastic input distance function approach on a sample of gher farmers. The results reveal evidence of a diversification economy in the rice-carp combination. Economies of scale exist in the 'gher' farming system. The level of technical efficiency is estimated …

The Decline Of Buffalo, New York In The Postwar Era: Causes, Effects, And Proposed Solutions, Carmen J. Bartolotta

History Theses

Buffalo, New York has undergone a precipitous decline in the postwar era, losing more than half its population and much of its economic base. The blame for this decline has traditionally fallen on failed government intervention, lack of quality local leadership, an overcompensated and under worked union workforce, environmental concerns, natural resource depletion, and oppressive taxes.

This study will focus on these various causes in an attempt to pinpoint the reasons for decline, not for the purpose or laying blame, but to set the groundwork for possible solutions that will stem the decline. The methodology for this study includes an …

The Role Of Landscape In The Distribution Of Deer-Vehicle Collisions In Two Counties In South-Central Mississippi, Jacob Jeremiah Mckee

Master's Theses

The number of deer killed by vehicle collisions each year in the United States exceeds the number of deer killed annually through hunting. Deer-vehicle collisions (DVCs) have a vast negative impact on the economy, traffic safety, and general wellbeing of otherwise healthy deer populations. To mitigate DVCs, it is imperative to gain a better understanding of the factors that play a role in their spatial distribution. Much of the existing research has been inconclusive, pointing to a variety of factors that cause DVCs that are specific to study site and region. Very little DVC research has been undertaken in the …

Star Messangers, Paul Zimet, Ellen Maddow

Kahn Institute Projects

Star Messengers is a musical theater work about two scientists, Galileo Galilei and Johannes Kepler, who changed our view of the universe. Writer Paul Zimet and composer Ellen Maddow have created a carnival of genres—opera, Com- media dell’Arte, Strindbergian Dream Play, and contemporary dance/theater—to produce a theatrical language that conveys the wonder of Galileo’s and Kepler’s discoveries.

While some aspects of Galileo’s life and discoveries are well known, hardly anything is popularly known of his scientific contemporaries. Johannes Kepler’s realization that the planets moved not in perfect circles, but in elliptical paths, was a leap of mind as extraordinary as …

A Multi-Scalar Approach To Theorizing Socio-Ecological Dynamics Of Urban Residential Landscapes, Rinku Roy Chowdhury, Kelli Larson, Morgan Grove, Colin Polsky, Elizabeth Cook, Jeffrey Onsted, Laura Ogden

Cities and the Environment (CATE)

Urban residential expansion increasingly drives land use, land cover and ecological changes worldwide, yet social science theories explaining such change remain under-developed. Existing theories often focus on processes occurring at one scale, while ignoring other scales. Emerging evidence from four linked U.S. research sites suggests it is essential to examine processes at multiple scales simultaneously when explaining the evolution of urban residential landscapes. Additionally, focusing on urbanization dynamics across multiple sites with a shared research design may yield fruitful comparative insights. The following processes and social-hierarchical scales significantly influence the spatial configurations of residential landscapes: household-level characteristics and environmental attitudes; …
