▼ 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

▼ 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…

▼ L’objectif de ce travail est d’explorer, d’une part,
comment la migration est influencée par le genre, à savoir le
système de croyances selon lequel les sociétés attribuent des
rôles, statuts et attributs psychologiques différents aux femmes et
aux hommes et, d’autre part, comment le rapport de pouvoir
hommes-femmes change en migration ou après la migration. Afin
d’illustrer cette double influence, je m’appuis sur une étude de
cas d’une population roumaine d’origine rurale installée dans la
région Latium-Rome, en Italie. La théorie de la structuration de
Giddens (1984) fournit de nombreux concepts utiles
(<i>agency</i>, conscience pratique, conscience
discursive, ressources d’allocation, ressources d’autorité) dans
l’explication de ce processus migratoire où les femmes et les
hommes occupent des places différentes. Leur migration même
contribue, en effet, aux réductions de certaines inégalités de sexe
et au développement social, économique et culturel de la
collectivité d’origine

▼ Four innovations in the fields of optical design and solar concentration are presented: a) the derivation of fundamentally new gradient-index (GRIN) distributions for perfect optical instruments. For the first time, GRIN lenses for visible and solar radiation with refractive index distributions that are amenable to current fabrication techniques are presented. Those lenses perform at nature's cardinal limits (within the geometrical optics approximation - valid for essentially all solar applications), i.e. perfect imaging and ideal nonimaging performance for monochromatic radiation and unprecedented image fidelity and near-ideal flux concentration for the full solar spectrum. Until now, there have been no GRIN solutions (for performance approaching the fundamental limits of flux concentration and image fidelity) that can accommodate an extended constant-index core - especially relevant because the only available fabrication techniques for visible and solar GRIN lenses require a constant-index core. b) The design, for the first time, of a nominally stationary solar concentrator with attainable geometric concentration of the order of 10super suns with high collection efficiency. The burden of tracking is transferred inside the stationary module where mm-scale motion of GRIN perfect imaging lenses tracks the sun. This creates the possibility for rooftop Concentrator Photovoltaics (CPV) with unprecedented optical performance and exceptional optical tolerance. c) The design of a nominally stationary solar concentrator with a modified Simultaneous Multiple Surface technique for nonimaging contoured lenses with flux concentration of the order of tenths of suns. d) The design of planar GRIN lenses able to deliver flux concentrations close to the thermodynamic limit to Solar Concentration with a single, optical element, previously deemed unattainable and particularly suitable to dual-axis tracking CPV.

▼ 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…

▼ Differences among individual responses to behavioral stimuli have been observed throughout a variety of taxa and these individual differences can affect female reproductive success and juvenile settlement decisions. In this study, we examined the effect of reversed sexual dimorphism on behavior phenotype and the effect of behavior on maternal reproductive success and juvenile dispersal of a fossorial rodent (Tamias dorsalis) in southeastern Arizona. We found that multiple behavioral phenotypes existed within this population and female litter size was not affected by behavioral type. We also found that natal habitat preference induction (NHPI) does occur at the population level, but only weakly occurs for the individual. We also found no effect of personality on site selection. Our results indicate that sex and mass may explain differences in behavioral phenotypes; however, individual behavioral differences are weakly related to female reproductive success and settlement decisions during juvenile dispersal.

▼ The climate of the Southwestern United States and northwestern Mexico is marked by a bimodal precipitation regime with the majority of moisture arriving during (1) the cool season via intermittent frontal storm systems (November to February) and (2) intense, convective storms during the North American Monsoon (NAM) (July to September). Fire season in the region occurs primarily during the arid fore-summer in May and early June prior to the arrival of the NAM. Most long-term tree-ring based studies of fire-climatology in the region have evaluated only the role of winter precipitation. We used tree-ring width based reconstructions of both winter and monsoon precipitation, coupled with fire scar based tree-ring reconstructions of fire history from twelve mountain ranges in the US and Mexico at the northwestern margin of the NAM to quantify the historical role of both seasons of precipitation in modulating widespread fire years. Winter precipitation was the primary driver of widespread fire years in the region, but years with drought in both seasons had the highest fire frequency and most widespread fires. The timing and amount of monsoon precipitation can be important factors in ending the most severe fire weather conditions. Monsoon drought coupled with earlier snow melt in the spring appears to contribute to an extension of fire weather for longer periods, leading to more and larger fires.

▼ 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…

▼ With the passage of Senate Bill #1 in 1997, Texans began a new era of regional water planning. The state's water policy is in the midst of a transformation. Water policy and decision makers are in the process of developing elegant, consensus-based solutions to water resource problems that were once thought to be unavoidable, unmanageable, and unsolvable. This study, using Preference-Feasibility Analysis (PFA) and descriptive statistics, identifies and discusses stakeholder preferences for water management strategies and planning considerations. The purpose is to identify points of consensus and points of divergence in order to develop a water plan for Texas that is fair and equitable. When a conflict is interest-based, as it is in the case of water resources, it is important to identify areas of give and take and to understand the positions of shareholders, especially when it comes to the implementation of management strategies that will inevitably affect some individuals negatively. The goal of this study was not to find the "perfect" strategy. Rather, the goal was to identify what is most important to regional and interest group shareholders. Such knowledge is imperative to the successful negotiation of management alternatives among water resource planners, managers and other interested shareholders. Once areas of agreement and contention have been recognized, planners and managers can use this information as a guide as they continue down the oath towards the sustainable development of water resources in Texas.

▼ In recent decades, the United States has experienced rapid growth and development that has threatened biodiversity and species habitat. In response to this and other environmental concerns of the 1970s, the United States congress passed the Endangered Species Act in 1973. This legislation has played a significant role in protecting species and their habitats. The purpose of this paper is to provide a description of habitat conservation planning as it stems from the Endangered Species Act. Habitat conservation planning was introduced by Congress in 1982 as a mechanism to alleviate conflicts between species protection and development pressures. This paper will analyze the impact of Texas State Senate Bill 1272 on habitat conservation planning in Texas. This legislation was passed by the State Legislature in May 1999 in response to concerns expressed by private landowners regarding the habitat conservation planning process. It is intended to discourage the creation of regional habitat conservation plans by establishing new guidelines for those initiating regional habitat conservation plans. This paper presents three sections providing an overview of the Endangered Species Act, habitat conservation plans, and the Balcones Canyonlands Conservation Plan in Travis County, Texas. This conservation plan is the flagship of urban, regional habitat conservation plans. Texas Senate Bill 1272 will be analyzed as it addresses the problems associated with habitat conservation planning in Texas.

▼ 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.…

▼ 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 ± 24538 ) , Children without asthma having complications ( NT 6448 ± 8880 ) , children with asthma not having complications ( NT 7396 ± 6434 ) , children with asthma having complications ( NT 12708 ± 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.

▼ In this thesis, detailed experiments are
performed to study the effect of the flow depth on turbulent
structures in smooth and rough bed open channel flow. When the
rough bed is introduced in the shallow flow, the local turbulence
near the roughness element intensifies and becomes highly
heterogeneous. The model roughness under study consists of a train
of two dimensional square ribs spanning the whole length of the
channel. The height of the ribs (k) occupy 10-15% of the depth of
flow (d) and falls in the category of large roughness. Velocity
measurements were conducted using laser Doppler velocimetry (LDV)
and particle image velocimetry (PIV) systems. While on the smooth
bed, mean velocity scaling in the classical logarithmic format was
confirmed from the present experiments, for the deep-flow cases,
turbulence quantities were found to be influenced by the free
surface. A modified length scale based on a region of constant
turbulence intensity is proposed to account for the effect of the
free surface. Two-dimensional PIV measurements were made in the
streamwise-wall normal plane of the smooth open channel flow at d =
0.10 m and Red = 21,000 to further study the influence of the free
surface on the turbulent structures. Proper orthogonal
decomposition (POD) and swirling strength analysis were employed to
investigate the structures present in the flow. Analysis of the POD
reconstructed velocity fields reveals the presence of large-scale
energetic structures near the free surface.

Smooth and Rough Wall Open Channel Flow Including Effects of

▼ 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.

▼ This thesis is a case study of the Fernandeño Tataviam Band of Mission Indians' (Tribe) multifaceted practice of Tribal Cultural Resources Management (TCRM) as it relates to projects subject to the California Environmental Quality Act (CEQA). Tracing the Tribe's journey to weave traditional stewardship principles into the contemporary fabric of TCRM, this thesis investigates how the Tribe utilizes TCRM to express, assert, and preserve its inherent sovereignty over the land and its resources. With a jurisdiction encompassing northern Los Angeles County, the Tribe is confronted with numerous land-altering activities that require strenuous review to eliminate potential adverse impacts to invaluable tribal cultural resources. Yet, there remains no legislation in place to ensure that the Tribe is compensated for the professional consultation services, assessments, and /or expertise it provides in this effort. Lack of funding is one of four key disruptions to productive TCRM addressed in this research, which also presents the Tribe's partial solutions to them. This thesis then demonstrates how the Tribe's proactive response to these impediments has removed a fraction of the financial burden of consultation off the Tribe, and helped support its TCRM department become more self-sufficient, while interrogating the current policies that have necessitated such actions.

▼ My MFA Thesis exhibition, Scene of Shipwreck, is a synthesis of my practice as both an object and exhibition maker. Centered around the narrative described by survivors Henri Savigny and Alexandre Corréard of the raft of the French Frigate Medusé, I have constructed a number of rafts to explore context, materiality, and symbolism in a liminal space. The potentiality of both is used for revelation and concealment...or concealment through revelation...or the vice versa. This paper reveals the mask of the historical, philosophical and referential tropes to show their relationship to the emotional or poetic.

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.

Photodegradation of dissolved organic matter (DOM)
due to ultraviolet (UV) exposure can have important consequences
for coastal zone productivity. The availability of UV radiation to
aquatic environments has increased due to ozone depletion.
Chromophoric DOM affects the amount of light penetration in a water
column. Ecosystem productivity depends in part on the input of DOM
into a coastal zone. DOM can protect animals, plants, and microbes
from damaging UV light by acting as sunscreen, resulting in
increased ecosystem productivity. Alternatively, DOM can decrease
ecosystem productivity by absorbing light needed for photosynthesis
and forming reaction products that are harmful to coastal zone
biota. Increased urbanization of watersheds and seasonal
differences in weather patterns change the delivery pathways,
reactivity, input, and energy flow of DOM into aquatic systems.
Understanding the input and reactivity of DOM in coastal systems as
a function of land urbanization and season will help determine the
fate of irradiated organic matter and its potential role as a
sunscreen in coastal waters. The consequences of energy flow from
UV radiation to DOM in aquatic systems will provide useful
preliminary data to be used for land-use planning in tributary
regions. This study also provides data useful for predictive models
of the fate of irradiated organic chemicals and the resultant
impact on water quality. In this paper, the study of watershed
urbanization and season on the input and photodegradation of DOM in
coastal waters is discussed based on organic carbon analysis,
UV-Visible spectrophotometry, microbial processing of DOM, and
terrestrial (land-use) analysis.

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…

The North Shore streams of Lake Superior are known
for their clear cool waters that flow through expanses of
undeveloped land. However, many North Shore watersheds are
experiencing rapid urbanization, resulting in increased impervious
surface cover (ISC). Previous research on the impact of ecological
disturbances on stream health have seldom focused on ecosystem
processes such as stream metabolism. This study assesses the effect
of increasing urbanization on whole stream community respiration
(CR) and gross primary production (GPP) rates during summer and
autumn base flow periods for nine low productivity, heterotrophic
streams spanning a watershed ISC gradient. Land cover was measured
as a percentage of the whole watershed and by distance-weighting to
evaluate the possible influence of spatial position of land cover
on stream function. Stream metabolism rates were determined using
high frequency diel dissolved oxygen changes at a single station
coupled with propane evasion to estimate stream reaeration rates.
GPP estimates ranged from 0.02 to 2.02 g O2 m-2d-1 and CR from 0.17
to 6.09 g O2 m-2d-1. During summer base flows there were strong
correlations between urban development measures and both stream
metabolism and nutrients. However, the associations between land
use and stream metabolism were not observed during the autumn base
flow period. Our data suggest the variability in stream flow and
leaf off along with stream temperature changes appear to be the
dominant factors influencing the relationship between land use and
stream metabolism in these Lake Superior tributary streams.
Distance-weighting did not improve the predictive power on stream
metabolism and water chemistry variables.

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.
