The Lived Experience Of God And Its Evolution In Children And Adolescents, Anne P. Devenish

Theses: Doctorates and Masters

Children's and adolescents' spirituality is important, especially to those entrusted with their education. To effectively nurture children's spirituality, parents, teachers, and ministers would benefit in knowing how young people experience God, what they think about God and how they relate to God: in effect, their lived experience of God. Learning about these phenomena could help greatly in communicating with children and adolescents about God. This study aims to build on the work of those who have investigated elements of the spirituality of children and adolescents in a qualitative way.

Methods For The Estimation Of Missing Values In Time Series, David S. Fung

Theses: Doctorates and Masters

Time Series is a sequential set of data measured over time. Examples of time series arise in a variety of areas, ranging from engineering to economics. The analysis of time series data constitutes an important area of statistics. Since, the data are records taken through time, missing observations in time series data are very common. This occurs because an observation may not be made at a particular time owing to faulty equipment, lost records, or a mistake, which cannot be rectified until later. When one or more observations are missing it may be necessary to estimate the model and also …

Sources Of Nitrogen And Phosphorus In Stormwater Drainage From Established Residential Areas And Options For Improved Management, Surasithe Khwanboonbumpen

Theses: Doctorates and Masters

From early April 2002 to June 2003, a study was conducted at Wanneroo and Bannister Creek in Perth's metropolitan area (Western Australia), aiming to quantify major sources of nitrogen (N) and phosphorus (P) entering urban residential catchments on two of the major dunal systems. The export of N and P from these catchments in stormwater discharge was measured, allowing investigation of some of the key pathways through which N and P enter the drainage network from the catchment. This information was then used to recommend catchment management approaches to reduce nutrient discharge into stormwater.

The Sustainment Of Early Childhood Teachers In The Classroom, Pamela A. Kilgallon

Theses: Doctorates and Masters

The changing nature of teaching has led to an increased focus on the retention and productive engagement of teachers in the classrooms. The ongoing implementation of educational change, accompanied by an ageing trend amongst teachers and rising incidences of teacher attrition, stress and burnout, highlights the importance of teachers being sustained in their profession. Furthermore, recognition of the value of early childhood education has drawn attention to early childhood teachers' abilities to be sustained in their teaching practice, effectively engaging students in the learning process. Acknowledging these issues, this study examined factors that influence early childhood classroom teachers' sustainment in …

Soil Community Structure And Litter Decomposition Under Irrigated Eucalyptus Globulus In South Western Australia, Derek J. Swarts

Theses: Doctorates and Masters

Plantations provide a range of benefits, including the potential to ameliorate salinity and soil erosion, enhance biodiversity, and provide timber and wood chips. They are increasingly important because of their role in carbon sequestration (Adolphson, 2000; Anonymous, 2005; Jones et al. , 2005; Kozlowski, 2002; Paul and Polglase, 2004). Recent research has highlighted the connection between plantation health and soil fertility (Johnston and Crossley Jr, 2002). Within an Australian context there is little published data on the composition of the soil and litter fauna and their contribution to litter decomposition under plantation systems (Adolphson, 2000). The Albany Effluent Irrigated Tree …

Insurance: A Consumer's Perspective, Elizabeth Ann Nanke

Honors Program Theses

Life insurance is a pivotal part of the world in which we live, and yet most consumers think about it very little. Life insurance started with the Ancient Greeks and continued to develop in Europe, eventually reaching the United States. Throughout history, insurance companies have undergone a number of modifications to match changing consumer needs. ln our modem society, insurance can be best defined as an intermediary that reduces the financial drain caused by the death of an individual by apportioning this loss among a very large group. Today, insurance companies sell a number of diversified products, but most insurance …

Asbestos Litigation And Indemnification, Paul Grammens

Honors Program Theses

Asbestos started out as an amazing product. It was not only easy to manufacture and easy to work with but also fire resistant and a great insulator, asbestos became one of the most common manufacturing products in the United States, especially after World War I. What the public did not know about asbestos at the time is that long-term exposure could lead to sickness. Because of this unforeseen liability, industrial companies and insurance companies were not able to properly prepare for the losses due to asbestos.

Educating Students To Be Better Citizens: Effects Of Service-Learning Courses On Civic Attitudes And Engagement, Aubree Rae Johnson

Honors Program Theses

Why focus on democratic outcomes? According to Benson, Harkavy, and Hartley (2005), service learning can be defined as: "an active, creative [pedagogy] that integrates community service with academic study in order to enhance a student's capacity to think critically, solve problems practically, and function as a lifelong moral, democratic citizen in a democratic society" (p. 189). Given this definition of service-learning, it follows that "service learning should work to develop strategies and actions to help fulfill the democratic promise of America's colleges and universities in particular and the democratic promise of American society in general. We should, therefore, evaluate service-learning …

Designing Healthy Spaces: Physical And Emotional Response To Color In Built Environments, Megan A. Smith

Honors Program Theses

The purpose of this study is to provide evidence that color, as an environmental factor, reaches far beyond mere aesthetics, and has very real effects on human beings. Furthermore, based upon a literature review, I will provide a framework for healthcare designers to aid in their color and finish selection in order to be the most beneficial to the captive and non-ambulatory populations in healthcare settings.

Educational Ideas And The Future Of Our Society, Mallory Sue Smiens

Honors Program Theses

Thus, the study of children and educational theories provided a rationale for the present study. Further discussions led to the belief that the questions raised by the author would best be answered from a sociological perspective. Because sociology is often employed to study people and how they interact with one another, it provides a meaningful discipline to weigh the teacher preparation ideas and practices against in order to determine their wider consequences for individuals. Therefore, a study of basic sociology was undertaken.

The Earned Income Tax Credit, Taxes, And Food Stamps: Their Effects On Minimum Wage Workers By State, Aaron William Popp

Honors Program Theses

The federal government spends billions of dollars annually on programs to lift low income workers out of poverty, but the money is not necessarily efficiently spent. If the benefits provided by the government provide a work incentive, then to increase the income of a worker by $1 requires more than $1 in government funds. Some programs, however, do provide an incentive for people to work. Given the complexity of the federal bureaucracy, few people have tried to compute the income that minimum wage workers would expect to earn given a set of government benefits that they receive and a number …

Markets For Markets: Origins And Subjects Of Information Markets, Miriam A. Cherry, Robert L. Rogers

All Faculty Scholarship

This Article focuses on why information markets have covered certain subject areas, sometimes of minor importance, while neglecting other subject areas of greater significance. To put it another way, why do information markets exist to predict the outcome of the papal conclave and the Michael Jackson trial, but no information markets exist to predict government policy conclusions, Supreme Court decisions, or the rulings in Delaware corporate law cases? Arguably, from either a dollar value or a social utility perspective, these areas of law and business would be more important than the outcome of, say, the Jackson trial. Why, then, do …

Radon In Caves: Clinical Aspects, Stephen A. Craven, Berend J. Smit

International Journal of Speleology

Historical, experimental and clinical evidence is presented to suggest that radon constitutes a relatively small carcinogenic risk for casual visitors to caves. The risk is dependent on radon levels and the smoking of tobacco. Show cave guides, chronically exposed to radon, may be at increased risk for lung cancer due to the effects of radon, especially if they are smokers of tobacco.

Exploring The Relationship Between Mathematics Content Knowledge And Pedagogical Content Knowledge Among Pre-Service Teachers, Hsueh-I Martin Lo

Dissertations and Theses @ UNI

This study replicates and extends a previous study (Nathan & Petrosino, 2003) that explored the relationship between the content knowledge and pedagogical content knowledge of pre-service mathematics teachers.

In that study, Nathan and Petrosino (2003) examined and reported evidence supporting the counterintuitive hypothesis that, in some situations, having a high degree of content knowledge may be associated with the "expert blind spot" (symbol-precedence) in pedagogical content knowledge. Pre-service teachers with various levels of expertise in mathematics subject matter were given a series of mathematics problems and asked to rank order their difficulty. Nathan and Petrosino (2003) reported that, on the …

Biotechnology Education In The State Of Iowa: A Survey Of Teachers And Factors Affecting Inclusion, Jason Allen Lang

Dissertations and Theses @ UNI

This research studied biology, agricultural education, and family and consumer science teachers in Iowa regarding the topic of biotechnology in their classrooms. The survey study involved collecting demographic information about respondents, which could then be used to characterize those who teach biotechnology and those who do not. The survey also asked about perceived barriers to teaching biotechnology. As the first large scale sampling of Iowa teachers (1477), the survey attempted to provide a picture of biotechnology education in the state. Demographic data showed an aging teaching population, a teaching load of some teachers, especially those in FCS and Ag Ed, …

Iep Team Decision-Making Process In The Reintegration Of Special Education Students: A Qualitative Analysis Of Exiting Decisions, Kenneth G. Hayes

Dissertations and Theses @ UNI

The purpose of this study was to take an in-depth look at the decision-making process that an IEP team goes through regarding the reintegration of special education students. In particular, this study looked at the exiting criteria used by an IEP team in determining whether or not a student should be exited back into the general education classroom prior to graduation. Furthermore, using Raven's (1992) Power/Interaction Model as the theoretical framework, this study also looked at the beliefs, perceptions, and attitudes of an IEP team that were adopted through the processes involved in exiting students from special education programs.

The Range Of Angles In The Euler-Gergonne-Soddy Triangle, David J. Gisch

Dissertations and Theses @ UNI

For any triangle one can construct its Euler-Gergonne-Soddy triangle (EGST). In 1996 it was shown that the EGST is always a right triangle. In this work we compute the range of the other angles of the EGST by calculating the maximum angle of the EGST at the de Longchamps point.

Effects Of External Rewards On Elementary Students’ Motivation To Read Independently, Benjamin David Olsen

Dissertations and Theses @ UNI

In an age of increased accountability, even down to how well, and how much, students read independently, teachers are looking for ways to motivate students to read. One popular way schools and teachers have looked to increase motivation is with reading incentive programs. Despite this widespread enthusiasm for such programs there has not been solid, replicable research that has supported the continued use of incentive programs to increase students' future motivation to read. This study examined how a reading incentive program affected students' motivation and attitudes toward reading and the time they spent reading. Research was guided by the following …

The temporal distribution of chloride, nitrate, and sulfate in the hydrologic environment were studied in Grundy County, Iowa from June to September 2004. The goal of the project was to investigate the rate of soil erosion and the subsequent loss of nutrients from the agricultural fields of the study area. Water samples were collected weekly from 6 different sites along Munns Creek in the study area near Grundy Center, Iowa. Each sample was analyzed for chloride, nitrate, and sulfate by ion chromatography. Soil core samples were collected from 22 locations in the surrounding agricultural fields. At each location, soil was …

Teacher Autonomy : A Review Of The Research Literature, Jaime A. Usma-Wilches

Graduate Research Papers

This paper reviews conceptual and empirical research on teacher autonomy in the context of school reform across countries. Research shows that teacher autonomy can be conceptualized as a personal sense of freedom from interference or in terms of teachers' exercise of control in four different school domains: Teaching and assessment, curriculum development, school functioning, and professional development. Research also confirms that teachers' autonomy for decision making is shaped by a number of personal and contextual factors, and that teachers' directed professional development experiences may enhance their autonomy. This review clarifies the meaning of teacher autonomy and other related terms, and …

Observed Web Robot Behavior On Decaying Web Subsites, Joan A. Smith, Frank Mccown, Michael L. Nelson

Computer Science Faculty Publications

We describe the observed crawling patterns of various search engines (including Google, Yahoo and MSN) as they traverse a series of web subsites whose contents decay at predetermined rates. We plot the progress of the crawlers through the subsites, and their behaviors regarding the various file types included in the web subsites. We chose decaying subsites because we were originally interested in tracking the implication of using search engine caches for digital preservation. However, some of the crawling behaviors themselves proved to be interesting and have implications on using a search engine as an interface to a digital library.

Wireless sensor network refers to a group of sensors, linked by a wireless medium to perform distributed sensing task. The primary interest is their capability in monitoring the physical environment through the deployment of numerous tiny, intelligent, wireless networked sensor nodes. Our interest consists of a sensor network, which includes a few specialized nodes called processing elements that can perform some limited computational capabilities. In this paper, we propose a model called SPLAI that allows the network to compute a finite element problem where the processing elements are modeled as the nodes in the linear triangular approximation problem. Our model …

Synchronization And Multiple Group Server Support For Kepler, K. Maly, M. Zubair, H. Siripuram, S. Zunjarwad, Yannis Manolopoulos (Ed.), Joaquim Filipe (Ed.), Panos Constantopoulos (Ed.), José Cordeiro (Ed.)

Computer Science Faculty Publications

In the last decade literally thousands of digital libraries have emerged but one of the biggest obstacles for dissemination of information to a user community is that many digital libraries use different, proprietary technologies that inhibit interoperability. Kepler framework addresses interoperability and gives publication control to individual publishers. In Kepler, OAI-PMH is used to support "personal data providers" or "archivelets".". In our vision, individual publishers can be integrated with an institutional repository like Dspace by means of a Kepler Group Digital Library (GDL). The GDL aggregates metadata and full text from archivelets and can act as an OAI-compliant data provider …

No Child Left Behind (2001) And High Stakes Tests : How They Affect Teachers' Experiences In The Classroom, Emily N. Olson

Dissertations and Theses @ UNI

The purpose of this study is to investigate whether No Child Left Behind (2001) and high-stakes tests affect teachers' experiences in the classroom, in areas such as instruction, attitude/anxiety, and job satisfaction. This study also investigates whether teachers in schools labeled "in need of improvement" are affected differently than teachers in schools that are not labeled. Thirty-eight teachers in four urban elementary schools in Iowa who work with 3rd, 4th, and 5th grade students responded to a 30-question survey that used a 5-point Likert scale. Data were analyzed using descriptive statistics as well as ANOVA to investigate a possible difference …
