▼ The study was initiated to explore the management and utilization of educational material resources in selected secondary schools of North Shoa. It attempted to identify. How are educational material resources managed and utilized to achieve educational objectives in secondary schools? To realize the purpose of the study, descriptive survey research design was selected which helps researcher to have understanding of the problem by studying the current status, nature of the prevailing conditions, practices and trends through relevant and precise information. Mixed research method is particularly important in complementing the limitation of each method by another. Both primary and secondary sources of data were used in the study. Three different but complementary data collection instruments such as questionnaire, interview and FGD were used for the sampling technique. Whereas, FGD participants (selected teachers and administrative staffs), interview participants (WEOH, principals and administrative staffs) and questionnaire participants (teachers) where selected. Accor0dingly, the study was carried out on five secondary schools that were selected using random sampling technique. The study also involved 81 teachers, 5 secondary school principals, five WEOH, and eleven administrative staffs; the total of 102 respondents. Data were analyzed and interpreted using both quantitatively and qualitatively. The data collected through questionnaire were analyzed quantitatively: percentages and mean were used; qualitative data collected through interviews and FGDS and open ended questions were analyzed by explanation as well as in narrative form. The finding of the study revealed that, there are noticeable short coming in the management of educational material resources. Among these, in adequate 5knowledge of principals and school board in resource management, delay in purchasing, lack of gathering pertinent information during purchasing, lack of utilization of available resources exhaustively, delay in distribution of material resources, lack of exchange of information among distribution and allocation bodies, lack of need assessment during planning and inventory control were the major challenges in the management and utilization of educational materials resources. Accordingly, the conclusion drawn is that the management of educational material resources in secondary schools under consideration was less than expectation. Finally, recommendations for addressing this issues were proposed as, among other things provision of awareness raising instruction, organizing a committee responsible for material resources management and utilization, conduct research by DOFED and OFED as to how to improve the function of the organization, developing a sense of ownership among the school community and preventive maintenance for wanton or other damages so as to improve the management and utilization of educational material resources Advisors/Committee Members: Hailesellassie Woldegerima (Asst. prof) (advisor).

▼ Strategic management is concerned with how firms develop and sustain competitive advantage. Performance being the ultimate goal depends on the sustenance of the competitive advantage in the end. Several theories have been brought forth to try to explain this phenomenon, but currently there still exist inconsistencies and studies done have been inconclusive. Since large manufacturing companies in Kenya have the same motivation of optimizing performance, they may use their varied dynamic capabilities to alter existing resource base to counter the ever-changing effects of environmental dynamism in order to achieve sustainable competitive advantage. This study conceptualized the relationship between organizational resources, environmental dynamism, dynamic capabilities and organizational performance of large manufacturing companies in Kenya. The study used a structured questionnaire to obtain data from managers of 56 large manufacturing companies listed in the Kenya Association of Manufacturers database of 2014, which were analyzed using descriptive and inferential statistics. It was observed that several factors influence performance, key among them being organizational resources. The study revealed that organizational resources have significant influence on organizational performance; organizational resources has significant influence on dynamic capabilities; the external dynamism has no significant moderating influence on the relationship between organization resources and dynamic capabilities. Dynamic capabilities have no significant intervening influence on the relationships between organizational resources and financial performance but have a significant intervening effect on the relationship between organizational resources and non-financial performance; the joint effect of organizational resources, dynamic capabilities and environmental dynamism on organizational performance is significantly different from the independent effect of each study variables. Theoretical implications of the study illustrate full support of the resource-based theory from dynamic capabilities, evolutionary theory from dynamic capabilities, stakeholders’ theory from organizational performance, open system theory and contingency theory from environmental dynamism. Methodological implication show operationalization of the organizational resources as an independent variable, environmental dynamism as a moderating variable, dynamic capabilities as the mediating variable and organizational performance as the dependent variable. All the indicators were measured using Likert type scale. Managerial implication illustrate that organizations embrace the sustainable balanced scorecard performance measurement, employ organizational resources through altering the same using dynamic capabilities regardless of the degree of environmental dynamism. This study was able to confirm that the resource based theory; evolutionary economic theory and stakeholders’ theory are relevant. It was also able to provide a link between the resources based view theory and…

▼ Seaborne cargo trade accounts for over 80% of the physical volume of global trade. Maritime transport thus fulfills an integral function in the economy of the world. South Africa generates approximately 3.5% of the world’s seaborne trade by value and 1.61% by tonnage, but the business of shipping all that cargo is undertaken by foreign firms. Operation Phakisa, the Comprehensive Maritime Transport Policy, and the South African Maritime Road Map, in pursuance of the National Development Plan, aim to revive the commercial maritime sector. In order to meet the demand for the skills and innovative abilities sought at executive and managerial levels in the commercial maritime sector, higher education in the knowledge of maritime business is increasingly becoming a prerequisite. Investment in higher education of quality and relevance in the maritime field would contribute to achieving the goals of the government for harnessing the potential of South Africa’s blue economy. The literature is researched in order to establish an authoritative view that the knowledge and the inspiration for entrepreneurial activity in the maritime sector can be imparted through higher education; and for example, that a viable shipping sector can contribute to the growth of a country’s economy. The South African maritime sector is then described. The commercial maritime higher education available at universities and other institutions of higher learning in South Africa, as well as in other African countries and elsewhere in the world, is examined, in order to be able to identify the degree and diploma courses available. Maritime courses imply not only the content of the educational material, but also the method whereby the knowledge is instilled in learners, and which extends well beyond the classroom. A survey, by way of the personal interviews of leaders in maritime business, maritime government affairs, and academics teaching maritime topics, is then undertaken to ascertain their views on the education required to promote the maritime sector in South Africa, using the list of subjects available for study worldwide, to assist their choice. The literature research and the interview survey by design also enable the secondary aims of the study to be achieved. Those aims include determining how awareness of the maritime domain could be raised and how co-operation between academia, business, and government, known as the triple helix could be organized, to promote the growth of the maritime sector. The results of the survey are analyzed and tabulated, in order to illustrate the extent of the agreement between those interviewed and the conclusions reached. These conclusions establish: (i) that the commercial maritime education currently available in South Africa, is inadequate to meet the aim of the government to the sector; (ii) that a post-graduate degree iv in the specified maritime studies incorporating a period of internship, and following on the first degree in business subjects, is required; (iii) that a triple helix of co-operation between…

Ph.D. University of Hawaii at Manoa 2014.

This dissertation consists of three separate empirical work on human resources especially focusing on how earlier decisions or behaviors of minors or young adults affect their economic outcomes in the later stages of their lives. In Chapter 1, I estimate the effect of marijuana decriminalization law on fertility. There has been a huge debate on regulations of marijuana over the past four decades. Possession of a small amount of marijuana was decriminalized in Nevada in October 2001 and in Massachusetts in January 2009. I find that there are about a 4.5 percent-age point increase in the probability of childbearing in Nevada and a 1.1 percentage point increase in Massachusetts after the decriminalization laws were implemented. Chapter 2 is a collaborative work with Dr. Sang-Hyop Lee. We investigate wage differentials between major switchers and stayers. U.S. universities allow students to change majors. Understanding this university policy is important because whether students make a right decision at the right time might have significant effects on future income. Individual's observed and unobserved characteristics affect self-selection mechanism of switching majors, which will also influence the labor market outcome. We find that for males, upward switchers gain pecuniary benefit from switching although they do not outperform stayers in a lucrative major. On the other hand, female upward switchers do not gain pecuniary benefit from switching. This suggests that ability sorting mechanism after entering college may explain earnings differential among lucrative graduates. In Chapter 3, I investigate the probability of having a STEM occupation after earning a bachelors degree. It has been well documented that workers in science, technology, engineering, and mathematics (STEM) fields affects economic growth and development, national security and innovation, and competitiveness in the global market. For these reasons, federal agencies have been making a billion-dollar investment every year to increase the number of students and graduates and to improve STEM educational programs. However, the linkage between educational attainment and employment in STEM fields has been little studied. I find statistical evidence that a non-trivial fraction of non-STEM graduates also work in the STEM fields after graduation.

▼ The Bouteloua curtipendula (Michx.) Torr. complex (BCC) is composed of 11 species and five varieties distributed in North and South America with its center of diversity in Mexico. It is characterized by tremendous morphological variation and taxonomic complexity that is most likely due to reticulate evolution, phenotypic plasticity, and the development of asexual reproduction (apomixis). Climate-induced range changes over evolutionary time may explain the origin of the morphologically diverse BCC as suites of species came into contact over time, hybridized, and created new species, cytotypes, and reproductive modes. I investigated the origins of the BCC by creating habitat suitability models based on present-day occurrence records for eight BCC taxa and hindcast these models to paleoclimate reconstructions for the Last Glacial Maximum and Last Interglacial. By estimating range dynamics over time, coupled with phylogenetic data, I inferred the locations of contact zones among taxa and identified likely progenitor taxa for various cytotypes found in the BCC. Species with large and environmentally heterogeneous distributions may have large ranges due to plastic responses to environmental variation for adaptive traits or they may maintain differently adapted ecotypes to specific habitats. I evaluated phenotypic plasticity for stolon and rhizome production in the three taxonomic varieties of B. curtipendula. My results indicate that expression of these traits is correlated with specific, local environmental conditions and not to broadly defined environments in geographic space and that phenotypic plasticity accounts for a greater proportion of trait expression than does total genetic variance. Apomixis, asexual reproduction via seed, most likely results from interploidy hybridization. There are many possible pathways that lead to asexual seed formation and understanding these pathways is important to understanding genetic diversity, demography, and evolutionary potential in apomictic and mixed apomictic-sexual populations. I discovered that B. curtipendula var. caespitosa, the only recognized apomictic taxon in the BCC, is pseudogamous, indicating that although fertilization is unnecessary to produce the embryo, it is necessary to produce the endosperm. These data also indicate that meiosis is highly irregular and results in sperm nuclei with variable chromosome numbers, which affects endosperm production, fertility and demographics in apomictic B. curtipendula.

▼ Zambia’s ethnic groups have each developed indigenous practices and systems that make up their Indigenous Knowledge (IK). This IK has not been adequately documented nor has it been used in modern approaches to natural resource conservation. IK is useful not only in managing water resources but also in ameliorating climatic variances that occur in form of droughts and floods. Such Indigenous Knowledge encompasses more than water resources management, it also takes into account other systems that play a role in the resources such as land use practices and trees. This study focused on exploring and documenting Toka Leya IK in relation to water resource management and establishing whether or not IK could be used in synergy with Integrated Water Resources Management and vice versa in the study area. The study analysed the Toka Leya IK in relation to water management and compared them to tenets of IWRM. The general research question posed in this study was: How can IK and IWRM be used in synergy to achieve sustainable water resources management among the Toka Leya of Chief Sekute? In order to achieve the research aim, specific research questions that were posed were: (1) What indigenous views are held by the Toka Leya of Chief Sekute’s Chiefdom about water? (2) Are the indigenous water practices of the Toka Leya people compatible with IWRM practices? (3) Is it feasible to incorporate the Toka Leya IK in IWRM and vice versa? Data collected was largely qualitative and hence its analysis was descriptive. The respondents were purposively sampled from the Chiefdom and Government offices directly involved in water and sanitation in the district. Key findings of the study were that the Toka Leya view water as a vulnerable and finite resource that should be conserved. The Toka Leya also use indigenous practices such as the use of flora to locate underground water sources and the basic principle of surface water retention after the wet season. There were rules and regulations that governed the abstraction and use of water resources that ensured sustainable use of the available water resources for the whole community. The rules and regulations also ensured the conservation of other natural resources such as flora more importantly riparian and high water table indicator trees. The conclusion of the study was that Toka Leya IK is indeed compatible with IWRM tenets. It is evident that Toka Leya IK has aspects that encourage participatory approach in water management. Women are not excluded from the management of water and water resources are not viewed as a free gift. Water is not considered as infinite in supply. As such the two approaches can be used in synergy to achieve sustainable water resources management in the study area. Key recommendations are that more future research be undertaken in IK along with botanical research that will validate the research findings that do not have scientific backing. Experts of IK, who are the indigenous people in any area, should be included during planning, implementation and monitoring of any…

Due to rapid urbanization and industrialization, the change in the land use pattern has resulted in irreversible anthropogenic disturbances to the hydrological processes. The increase in impervious area associated with urban development affects the hydrologic cycle and consequently there is an enhanced risk due to urban flooding. The increase in impermeable area decreases infiltration, increases the runoff and reduces the time of concentration. Hence, for a given amount of rainfall, greater flooding is realized. Even though flood is a natural hydrological phenomenon, human modification and new developments on flood plains had accentuated the problem. This may be due to little attention being paid to the social, political, environmental, ecological, institutional, economical and legal aspects of flooding while more emphasis is given to engineering aspects of flood control. The focus of the research is to bring the hydrologic, hydraulic, social and economic aspects of the flooding under the umbrella of Integrated Flood Management (IFM) that aims to combine all the characteristics of flooding and tries to give effective solution for the problem. It also argues that flood management measures will be successful if the policies are appropriate and adequate attention is paid to social issues involving stakeholders in the decision making process. The research aims to investigate the impacts of land use changes on runoff generation process and the problems associated with the flood management. In this study, Soft Systems Methodology (SSM) was used to address social and engineering problems arising due to flooding along Adayar River in Chennai, India. Two workshops were conducted in order to define and explore the problematic situation, the role of various actors involved, to develop the conceptual model, to rank decision-making criteria and to analyze the forces for and against the solution of the problem. It is found from the study that the effect of flooding tends to be severe due to formation of sand bar at the river

▼ South Africa relies heavily on fossil fuels, particularly coal, to generate electricity and it is a well known fact that the use of fossil fuels contributes to climate change, as it produces greenhouse gases (GHGs). In fact, internationally South Africa is the 17th highest emitter of GHGs (Congressional Research Service (CRS), 2008). Coupled with the environmental consequences of fossil fuel use, South Africa has a further responsibility of addressing the inherited backlog of electricity provision to the rural, and previously disadvantaged communities. In an attempt to address these two problems, the government issued the White Paper on Renewable Energy. In this paper, renewable energy alternatives are proposed to replace a portion of traditional electricity generating methods. Concentrator photovoltaic (CPV) energy generation is one such renewable option available to government. CPV uses optic elements (such as lenses) to concentrate sunlight onto solar cells. Owing to the light being concentrated, the cells in CPV use less semiconductor material, which makes them more efficient in comparison to conventional photovoltaic (PV) cells. CPV is a technology that operates well in regions with high solar radiation. As such, South Africa is particularly well suited for this technology, with average solar radiation levels ranging from 4.5 to 6.5 05 ℎ/. CPV is also well suited for off-grid application, which addresses electricity demand in remote rural areas. This study is an economic project analysis of the installation, operation, maintenance, and decommissioning of CPV technology in a rural area in the Eastern Cape, South Africa. The study area chosen for this purpose is the Tyefu settlement in the Eastern Cape. Tyefu was deemed ideal for this type of analysis due to four characteristics. Firstly, Tyefu is a remote rural settlement at the end of the national grid. Secondly, the community is very poor and previously disadvantaged. Thirdly, many households are without Eskom generated electricity. Lastly, the study area is located in an area with ideal irradiance levels for CPV. Two methods of economic project analysis are applied to this case study, namely a costbenefit analysis (CBA) and a cost-effectiveness analysis (CEA). Additionally, two types of CBA are performed, namely a private CBA and a social CBA. The private CBA evaluates the Tyefu electrification project from a private investor's perspective and the social CBA evaluates the project from society's point of view. The CEAs carried out compare the costeffectiveness of the traditional PV technology to that of CPV in terms of private and social costs. The private costs and benefits of the CPV project were identified and valued in terms of market prices. Then, this cost benefit profile was used to calculate net benefits which in turn were discounted to present values using a private discount rate of 6.42 percent. Three decision making criteria were generated, namely the net present value (NPV), the internal rate of return (IRR) and the benefit cost ratio (BCR).…

▼ The necessity for this project was identified as a response to declining levels of science engagement, academic success and literacy observed in New Zealand secondary science education (OECD, 2016). As international advancements in sciences and technology create shifts in the current economic landscape, increasing importance is being placed on knowledge-intensive industries. This changed weighting of industry contributions to economic prosperity creates a simultaneous change in future workforce skill requirements (Gilbert & Bull, 2013). With the importance of education in long-term social and economic prosperity being long acknowledged, the changing economic climate intensifies the urgent need to address New Zealand’s declining science engagement and academic success. While the most significant facets of educational operations lie in education pedagogy and policy, the wide range of factors involved in educational outcomes yield expansive opportunities for potential innovations and commercialisation in the education sector. The opportunity for this project was derived from identifying the elements that contribute to these challenges, and isolating a gap in the market of science education resources. The purpose of this project was to research this potential market gap, as well as identifying how to appeal to it. This led to the proposal for the SciNow multimodal resource database, a resource database designed to provide engaging lesson and study materials to science students and teachers with an emphasis on real-life application of content. Through utilising the concept of multimodality, the database design proposes offering materials through ranging modes of communication to increase appeal to varying student learning preferences (Jewitt, 2008). The overall intention for the SciNow database is to raise attractiveness of science education by making it more interesting and relevant to students, thereby positively affecting educational outcomes and in turn leading to economic benefits in the form of a more ideally skilled workforce. While initial investigation focused on creating a business model for commercialising the SciNow resource database, this intention was adjusted in response to literature reviews revealing the significant performance gap between high and low achievers in science education (Education Review, 2016). In addition to New Zealand exhibiting one of the largest performance gaps in the OECD, concerns are exacerbated by the lowest performing population’s overrepresentation of Maori and Pasifika students and students from low socioeconomic backgrounds (OECD, 2015). In response to the level of inequality in science education, the SciNow proposal was adjusted to be provided to all students and teachers nationwide for free. The methodology implemented in this project was of a qualitative nature (Morgan, 1997). Interviews were conducted with secondary science teachers and students in which questioning focused on experiences with science education, including education resource availability and provision.… Advisors/Committee Members: Moeed, Azra.

▼ Background Children with asthma usually use more medical resources than those without asthma. However, studies on the relationship between ratios of asthma-related complications and consumption of medical resources are rare. Methods We sampled data from âRegistry for beneficiariesâ of âNational Health Insurance Research Databaseâ, National Health Insurance Institute, 2004. The target group was patients, aged between 1 and 18 years old, whose main diagnosis number from outpatient department (ICD-9-CM) is 493. Ratios of asthma-related complications and consumption of medical costs and resources were submitted to statistical analysis. Results Data of 394197 outpatients, of whom 62.5% are males, were included. Among the entire sample, 7627 children have asthma. Children with asthma are 8.2 times likely to get allergic rhinitis than those without asthma. Children with asthma are 2.1 times likely to get atopic dermatitis, 1.3 times likely to get otitis media, 1.5 times likely to get sinusitis than those without asthma. With regard to average expenditure on medical treatment, that of children with asthma is higher than that of children without asthma. Expenditures on medical treatment are compared among four divided groups. Children without asthma or complications ( NT 3714 Â± 24538 ) , Children without asthma having complications ( NT 6448 Â± 8880 ) , children with asthma not having complications ( NT 7396 Â± 6434 ) , children with asthma having complications ( NT 12708 Â± 10585 ) . Results of expenditures on medical treatment among these four divided groups show statistically significant. Seventy % of medical resources utilized are pediatrics, 40% are clinics, 50% are in the northern area. Conclusion Ratio of comorbidities of children with asthma is obviously higher than that of children without asthma. With regard to medical costs, that of children with asthma having comorbidities is higher than that of children with asthma not having comorbidities. Therefore, local pediatricians have an important role in the care of children with asthma. Advisors/Committee Members: Jen-Her Wu (chair), Ying-Chun Li (committee member), Lawrence Sun (chair).

▼ A comprehensive study was carried out to understand the effects of roughness, seepage and ice cover on the turbulence characteristics of flow in an open channel. To this end, tests were conducted with four different types of bed surface conditions. This includes the use of an impermeable smooth bed, impermeable rough bed, permeable sand bed and an impermeable bed with distributed roughness. Both suction and injection seepage tests were conducted covering a range of seepage rates. For the ice cover tests, two different cover conditions were used. The tests were conducted at two different Reynolds number (Re = 47,500 and 31,000). The bed roughness effect on the turbulence characteristics is seen to have penetrated through most of the flow depth, disputing the wall similarity hypothesis initially proposed by Townsend (1976). The results show that the distributed roughness shows the greatest roughness effect. Although the same sand grain is used to create the different rough bed conditions, there are differences in turbulence characteristics, which is an indication that specific geometry of the roughness has an influence. Roughness increases the contribution of the extreme turbulent events which produces very large instantaneous Reynolds shear stress and can potentially influence the sediment transport, resuspension of pollutant from the bed and alter the nutrient composition, which eventually affects the sustainability of benthic organisms. For the tests with seepage, injection increases the magnitude of the various turbulent characteristics and suction reduces the values in comparison to no-seepage condition. Effect of seepage on different turbulent characteristics is not restricted to the near-bed region but can be seen through out the flow depth. The results from the analysis of turbulent bursting events clearly show a distinct effect of seepage well beyond the near-bed region. The introduction of ice cover causes a change in mean velocity profile and increases total resistance of the channel. The magnitude of this change depends on both the bed and the cover roughness. The change in turbulent characteristics seems to be bound to the upper half of the flow and the changes can be significant with the rougher cover.

The St. Louis River drains an area of 9,412 km2 (3,634 mi2) and empties into the western arm of Lake Superior. Shortly downstream from the Fond du Lac Reservoir, the river opens up into a 48.5 km2 freshwater estuary that separates Minnesota and Wisconsin. A GIS-based anthropogenic stressor gradient was developed to characterize the anthropogenic stressors within the watershed. The components of the stressor gradient were: road density, point-source pollution permit density, population density, percent agricultural land and percent developed land. Water quality sampling was conducted at 26 sites in the estuary in both nearshore areas and above the mouths of the associated tributaries during multiple flow regimes in 2010-2011. Additional data were analyzed from 34 upper watershed sites sampled in 2009-2010. The stressor gradient was shown to be significantly, positively correlated (p<0.1) with TSS, turbidity, TP, NO2-/NO3 – N, DIN, dissolved oxygen saturation, pH, specific electrical conductivity, chloride , sulfate, E. coli, and hardness in the upper watershed. In the estuary it was significantly, positively correlated with NO2-/NO3 – N, NH4+-N, DIN, and chloride at multiple flow regime and location combinations. The strength of the correlations of the stressor gradient and water quality was generally improved by the removal of the less relevant agricultural component. Sediment-related parameters were either not correlated with the stressor gradient in the estuary or anomalously were negatively correlated. This was found to be due to the non-uniform distribution of more erodible soils. Soil K factor (an erosivity index from SSURGO) was significantly, positively correlated with the sediment-related parameters. Although it was originally designed to help stratify sampling programs across a gradient of stress and identify reference areas for restoration projects, the stressor gradient was shown to have some predictive power for multiple water quality parameters.

Corrosion of steel infrastructure in the Duluth-Superior Harbor (DSH) is a concern for those who own and maintain structures that are critical for maritime transportation. Long-term corrosion rates of steel structures in the DSH were 2 to 4 times faster than is typical for other freshwater habitats, ranging from 0.06 to 0.14 mm/yr. The highest rates of steel corrosion were found at moderately to severely corroded sites and were within the lower range for corrosion of steel in seawater. It is important to know the potential roles that water quality and microorganisms play in the corrosion process to better understand why steel structures in the DSH are corroding faster than expected and to develop methods to prevent or mitigate this problem. Dissolved oxygen increased and chloride and sulfate concentrations decreased in the late 20th century in the DSH after the Western Lake Superior Sanitary District became operational. In 2010, only alkalinity, chloride, and conductivity were positively related to long-term steel corrosion rates in the DSH and interestingly, dissolved oxygen was inversely related to it. The Larson-Skold Index, which measures the corrosivity of water towards steel, decreased or remained constant at three sites between 1972 and 1996. The Larson-Skold Index was usually below the threshold for concern in 2010-2011, indicating that changes in water chemistry alone may not be responsible for the severe corrosion of steel in this harbor. Gallionella, a genus of iron-oxidizing bacteria, was more abundant within corrosion tubercles on severely corroded steel structures in the DSH where more than 109 Gallionella 16S rRNA copies/dry g of tubercle were observed, representing 2% to 34% of the total prokaryotic cells recovered from these tubercles. Gallionella bacteria were less abundant (~107 copies/dry g) on steel structures at sites along the north shore of Lake Superior. DNA from Gallionella was not detected in the water surrounding corroding steel structures in the DSH or in harbors on the north shore of Lake Superior, indicating that these bacteria were enriched on corroding steel. Sulfate-reducing bacteria (SRB) were also more abundant within tubercles at severely corroded sites but at least 2 orders of magnitude less abundant than Gallionella bacteria, accounting for less than 1% of prokaryotic cells within these corrosion tubercles. Considered alone, neither the abundance of Gallionella or SRB was related to long-term steel corrosion rates in the DSH. A multiple linear regression model was developed using water quality parameters and bacterial abundances to predict steel corrosion rates. The model used alkalinity, sulfate concentration, and log10 transformed SRB abundance to predict the long-term steel corrosion rate. It overestimated the long-term corrosion rate of a steel structure in one harbor along the north shore of Lake Superior and…

Carbonate - sandstone geology in southeastern Minnesota creates a heterogeneous landscape of springs, seeps, and sinkholes that supply groundwater into streams. Air temperatures have been shown to be effective predictors of water temperature in surface - water dominated streams. However, no published work investigates the relationship between air and water temperatures in groundwater - fed streams across watersheds. We used simple linear regression models to examine air - water temperature relationships for 40 groundwater - fed streams in Southeastern Minnesota. A 40 - stream, weekly time scale, composite linear regression model has an R2 of 0.83, a slope of 0.38, and an intercept of 6.63. Regression models were also combined by common intercept and slope and split into winter and non - winter air temperature regimes to allow approximation of winter water temperature regimes based on non - winter data. The air - water temperature relationships for groundwater - fed streams are different in slope and intercept compared to surface - water dominated streams. The high R2 values demonstrate that air - water temperature regression models for groundwater - fed streams may be useful in predicting the thermal regimes for these systems under future climate scenarios. Climate change is expected to alter the thermal regime of groundwater - fed systems but will most strongly affect streams that are more vulnerable to climate change and will do so at a slower rate than surface - water dominated systems. A regression model of intercept vs. slope can be used to identify streams for which water temperatures are more meteorologically controlled than hydrologically controlled, and thus more vulnerable to climate change, with evidence provided by an investigation into the resulting mean summer water temperature under a moderate climate change scenario for various types of linear regression models. Modeling the possible increases in mean summer water temperature provides insight into the potential effects of climate change on the amount of suitable brown trout habitat as well as the possible effects on brown trout biological processes and behavior. Information on possible future thermal conditions and can be used to guide restoration versus management strategies to protect the thermal integrity of trout streams and ensure the persistence of their stenothermic communities.

Light is an energy source that affects the metabolism of an aquatic system by providing energy for photosynthesis, the thermal structure by the transfer of light to heat energy, and the chemical make-up by providing energy for both indirect and direct photochemical reactions. This thesis considers the use of two dyes (rhodamine WT and fluorescein) as a way to measure the amount of light affecting lotic systems. These dyes are common tracers usually used in aquatic systems to measure water flow and mixing. Rhodamine WT exhibits photo-stability; while fluorescein exhibits photo-lability. Combining these two could potentially provide a Lagrangian measure of sunlight exposure in a lotic system; a previously unattainable view of the light field in such systems. In this thesis, several lab experiments were performed to test the effects of temperature and pH on the fluorescence of the dyes and to test the effects of pH and wavelength of light on the photoresponse of the dyes upon irradiation. A correction factor for temperature was found in lab experiments that matched previously published results. When pH remained within the normal range of North Shore streams (6.99-7.54), rhodamine WT exhibited photo-stability while fluorescein exhibited photo-lability; however, changes in response were seen as a function of pH and there are indications that rhodamine WT may be photo-labile at high pH. Irradiation of the dyes showed that wavelengths at and/or above 420 nm degrade the fluorescein. The dual-dye approach was tested in Amity Creek, a designated trout stream located on the north shore of Lake Superior. During deployment along a given reach, the dyes showed robust applicability on base flow, high irradiance days but no appreciable photoresponse on high flow days. During base flow deployments, the fluorescein to rhodamine WT ratio decreased linearly over time (with an R2 ranging from 0.971-0.998). Overall, in-stream Lagrangian deployments showed similar degradation rates to those seen in batch samples of stream water placed on the stream bed in a fixed position in sunlight for the same period of time. This concurs with visual observations that there is no significant canopy cover down this stream reach. Although the dual-dye methodology was successful in acting as an in situ light monitor and is applicable to streams if temperature is recorded and pH is within a certain operating range, more work needs to be done to demonstrate if the use of fluorescein and rhodamine WT is a practical alternative to current methods of light measurement.

Ship ballast water is a potential vector for the introduction and spread of aquatic nonindigenous species (NIS). Although most studies focus on invasive plants and animals, there is an increased interest in the potential for invasive microbes. The Duluth- Superior Harbor (DSH), located in a freshwater estuary at the confluence of Lake Superior and the St. Louis River, receives more ballast water discharge than any other Great Lakes port yet little is known about the bacterioplankton communities in the harbor or the ballast water released into the harbor. The two most important factors affecting the successful establishment of an aquatic NIS through ballast water discharge are propagule pressure, and the abiotic and biotic characteristics of the new environment. Water was collected at six sites in Lake Superior, the Duluth-Superior Harbor, and the lower St. Louis River to characterize bacterioplankton communities. Other water samples were collected from the ballast tanks of ten commercial ships visiting the Duluth-Superior Harbor and the Western Lake Superior Sanitary District (WLSSD) because these sources may influence the genetic structure and composition of natural bacterioplankton communities in the harbor. Three distinct bacterioplankton communities representative of Lake Superior, the Duluth-Superior Harbor, and the St. Louis River habitats were detected in water samples collected on one day in early September 2009 (ANOSIM, p < 0.05) using a DNA fingerprint analysis (T-RFLP). These results were consistent with findings of other investigations that found distinct bacterioplankton communities in estuarine mixing zones. Water temperature, dissolved organic carbon (DOC), ammonium (NH4 +), and nitrate (NO3 −) were more highly correlated with differences in the genetic structure of bacterioplankton communities along a transect from the river through the harbor than other environmental variables. DNA fingerprint analyses also indicated that bacterioplankton communities discharged into the DSH with ballast water and treated wastewater effluent were different from bacterioplankton communities found within the harbor. The most common bacterial phyla found in freshwater habitats (i.e., Alphaproteobacteria, Betaproteobacteria, Actinobacteria, Bacteroidetes) were also seen in 16S rRNA gene clone libraries of freshwater ballast and the Duluth-Superior Harbor. The genetic structure and species composition of the seawater ballast bacterioplankton community from an ocean-going ship was fundamentally different than the bacterioplankton communities in freshwater ballast, and was uncharacteristically dominated by bacteria from the Epsilonproteobacteria. Interestingly, three environmental DNA sequences from the seawater ballast of this ship were similar to Tennacibaculum soleae, a marine fish pathogen (phylum Bacteroidetes, Class Flavobacteria). DNA from this…

In urban ecosystems, households are important decision-making units that are resource consumers and contributors to urban water pollution. At the landscape level, individual household choices regarding lawn management vary greatly, contributing to the detriment or protection of water resources. To better target household behavior change, we need to understand the social influences that determine how and why households manage their lawns differently, and what characteristics of the household could be driving these differences. We suggest that a better understanding of households could inform targeted policies and programs for effective change strategies. By spatially examining income, house age and proximity to a lake, we analyzed whether household groupings reflect households that think and act in similar ways with respect to lawn management. We obtained data for this research through a 2008 mail survey completed by the Twin Cities Household Ecosystem Project in Ramsey and Anoka Counties, Minnesota. Responses to questions pertaining to fertilization, leaf and lawn clipping management, vegetation choice, and lawn management attitudes were analyzed. When households were grouped spatially across the landscape with respect to proximity to a lake, few significant differences were found between household groups within 200 meters vs. farther than 200 meters. While income did influence particular lawn management attitudes and behaviors, it did not group spatially at a county scale, or at the finer scale of Saint Paul, the major city in our study area. House age showed significant relationships with almost every attitude and behavior examined, and was the only factor to demonstrate important spatial grouping. The correlation of house age with lawn attitudes/behaviors, however, is partially an artifact of housing density and number of trees on a household’s property. This study demonstrates that it may be possible to target households based on particular factors in order to tailor educational programming and policy to influence lawn management behavior, reduce pollutants leaving household lawns, and therefore improve water quality.

To investigate early diagenetic processes and the spatial and temporal variability in organic-poor sediments of Lake Superior, we have repeatedly sampled sediments at 8 locations across the lake. Sediment geochemistry was characterized by the penetration depths and uptake rates of oxygen, and the distributions of organic carbon, dissolved Fe(II), nitrate, ammonium, soluble reactive phosphate (SRP), and solid phase Fe(III)/Fe(II) and phosphorus. Oxygen penetrated deeply into the sediments at all locations: from ~3.5 cm at near-shore stations to >12 cm in the deep basins. The total oxygen uptake ranged from 4.44 mmol m-2 d-1 to 7.68 mmol m-2 d-1, averaging 6.10 mmol m-2 d-1. Diffusive oxygen flux averaged 2.92 ± 0.75 mmol m-2 d-1. Aerobic respiration accounted for >90-95% of the total carbon degradation, with denitrification and iron reduction contributing <5% of the total carbon degradation. Reactivity of the organic carbon in the upper 1 cm of sediment was calculated to be ~ 1.2 yr-1, which is typical for organic material less than a year old. Sediment carbon degradation rate of 5.29± 1.20 mmol m-2 d-1 corresponds to ~ 19% of the recently estimated primary production. More than ~ 90% of carbon reaching the lake floor is mineralized, with a sediment carbon burial flux of 0.49 mmol m-2 d-1. Diffusive fluxes of nitrate from sediment into the overlying water averaged 0.17± 0.07 mmol m-2 d-1, recycling ~ 40% of nitrogen sedimentation flux. Phosphorus cycling was strongly associated with the diagenetic cycling of iron. Sediment diffusive effluxes of SRP were small (< ~ 1.5 x 10-3 mmol m-2 d-1) and similar among stations. The efficient trapping of phosphorus in the sediment is interpreted as a result of strong adsorption of phosphorus by iron (hydro)oxides. Sediments in Lake Superior exhibit strong spatial heterogeneity on spatial scales down to hundreds of meters. The presence of multiple Fe- and Mn-rich layers, forming dense crusts and often visible to the naked eye, suggests decadal or longer variations in the sediment’s physical or redox environment. Oxygen diffusive fluxes and carbon degradation rates exhibited strong seasonality, with higher oxygen fluxes and carbon degradation rates in July, and the depth of oxygen penetration varied by several mm to cm.
