Barriers That Iowa High School Biology Teachers Face When Teaching Evolution In The Classroom, Joshua Michael Hanna Jan 2011

Barriers That Iowa High School Biology Teachers Face When Teaching Evolution In The Classroom, Joshua Michael Hanna

Dissertations and Theses @ UNI

After decades of court cases, decided in favor of evolution being taught, legal decisions where the incorporation of teaching creationist ideas have been found unconstitutional, and recent strategies and attempts that would have teachers give "equal time" to creation-science ideas; there remains a disparity among Iowa's high school biology teachers when teaching evolutionary concepts in the classroom. Taking a look at what is being taught about evolution in Iowa classrooms, this study takes an in-depth look at what Iowa's biology teachers are teaching when educating their students about evolution, where emphasis is being placed and who is putting the most …

Using Novels In The Science Classroom, Hannah Llewellyn Haarhues

Dissertations and Theses @ UNI

Reading is a key factor in the success of students through their school years as well as their lives. With Americans reading less and falling behind in subjects as they progress through the school system, reading is the subject area that benefits all aspects of their schooling. Studies done from the 1990s on have shown successful reading programs improve standardized test scores of school age students. Trade books in place of textbooks had been explored, but only in middle school or younger. This study uses a survey to explore high school biology students' opinions on reading and science before and …

Robustness Analysis Of Slow Learning In Iterative Learning Control Systems, John R. Singler, Douglas A. Bristow Jan 2011

Robustness Analysis Of Slow Learning In Iterative Learning Control Systems, John R. Singler, Douglas A. Bristow

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This paper examines robust stability and robust transient growth in Iterative Learning Control (ILC). It is well known that small perturbations in system dynamics can result in very large transient growth of some ILC systems. Even larger perturbations can result in instability. One ad hoc technique commonly employed to improve robustness is to slow the learning rate by reducing the learning filter gain or lowpass filtering the error signal. Here, pseudospectra analysis is used to analyze the robustness of ILC algorithms with slow learning. It is found that robustness bounds can be increased and transient growth decreased with decreasing learning …

Examining The Use Of Collocations In Natural Language Processing, Patrick Anthony Burke Jan 2011

Examining The Use Of Collocations In Natural Language Processing, Patrick Anthony Burke

Dissertations and Theses @ UNI

Studies in Natural Language Processing are often dedicated to defining the lexicon and grammar rules of individual languages. It is a common understanding that virtually all statements that a language user encounters are unique constructions that have never been seen before. Because of this, there has been very little modem research regarding the use of repeated language when attempting to provide computers with language processing functionality. It seems reasonable that most statements we use on a daily basis are completely new when they are evaluated in their entirely. However, it is possible that smaller portions of these statements are reused. …

Management Of Wind Power Generation With The Attachment Of Wind Tunnel, Ulan Dakeev

Dissertations and Theses @ UNI

This study presents a new approach in which a wind tunnel apparatus is used to identify the efficiency of power output by a wind turbine with a 400W rating. Moreover, the study addresses a significant issue concerning the turbulence formed by a natural wind which can be eliminated or reduced with the use of the proposed wind tunnel. Wind power characteristics that indicate power output versus wind velocity are obtained by performing a number of case studies. The case studies include normal operation of the experimental wind turbine at variable wind velocity values with and without proposed wind tunnel. A …

Detailed Mapping Of The Local Ir⁴⁺ Dimers Through The Metal-Insulator Transitions Of Cuir₂S₄ Thiospinel By X-Ray Atomic Pair Distribution Function Measurements, Emil S. Bozin, Ahmad S. Masadeh, Yew San Hor, J. F. Mitchell, Simon J. Billinge Jan 2011

Detailed Mapping Of The Local Ir⁴⁺ Dimers Through The Metal-Insulator Transitions Of Cuir₂S₄ Thiospinel By X-Ray Atomic Pair Distribution Function Measurements, Emil S. Bozin, Ahmad S. Masadeh, Yew San Hor, J. F. Mitchell, Simon J. Billinge

Physics Faculty Research & Creative Works

The evolution of the short-range structural signature of the Ir 4+ dimer state in CuIr2S4 thiospinel has been studied across the metal-insulator phase transitions as the metallic state is induced by temperature, Cr doping, and x-ray fluence. An atomic pair distribution function (PDF) approach reveals that there are no local dimers that survive into the metallic phase when this is invoked by temperature and doping. The PDF shows Ir4+ dimers when they exist, regardless of whether or not they are long-range ordered. At 100 K, exposure to a 98 keV x-ray beam melts the long-range dimer …

Isolation And Analysis Of Peptides Binding To Helix 69 Of E. Coli 23 S Rrna From M13 Phage Display, Moninderpal Kaur

Wayne State University Dissertations

Peptides binding to helix 69 of domain IV or residues 1906-1924, of 23 S rRNA of E.coli were being selected from a heptapeptide phage library. An experimental system including biotin labeling of RNA and then affinity selection through four rounds was being followed. After sequencing phage clones of the fourth round, two peptide sequences dominated the phage pool, STYTSVS and NQVANHQ. The later sequence was a unique sequence since this sequence contained an abundance of amino acid residues that are also present in the ribosome recycling factor, RRF, and known to make contacts with H69. Phage-display methodology demonstrated the rapid …

Applications Of Electronic Structure Theory To Problems In Unimolecular Dissociation And Inorganic And Biochemical Systems, Jia Zhou Jan 2011

Applications Of Electronic Structure Theory To Problems In Unimolecular Dissociation And Inorganic And Biochemical Systems, Jia Zhou

Wayne State University Dissertations

In this dissertation, ab initio classical trajectory calculations have been carried out to study the dissociation of acetone radical cation, pentane-2,4-dione radical cation, and 1,3-cyclobutanedione radical cation. For acetone radical cation and pentane-2,4-dione radical cation, MP2 with bond additivity corrections generates a better potential energy surface at low cost and is thus used for molecular dynamics calculations. The dissociation of acetone radical cation is found to favor the loss of the newly formed methyl group in agreement with the experiments. The branching ratios of methyl loss were also calculated with different amount of excess energy and of specific mode excitation. …

Urban High School Students' Attitudes Toward Democratic Citizenship: A Comparison Of Students In The Njrotc Program And Students In Traditional Civics Classes, Ruthann Burns-Mcfadden Jan 2011

Urban High School Students' Attitudes Toward Democratic Citizenship: A Comparison Of Students In The Njrotc Program And Students In Traditional Civics Classes, Ruthann Burns-Mcfadden

Wayne State University Dissertations

Conscientious and informed citizenry is essential in maintaining the integrity of American democracy. On the other hand, continued lack of engagement in and lack of positive attitudes towards civic participation can cause democracy to suffer. During the 21st century, schools are expected to prepare and motivate students to participate in their government. Research provides evidence that a positive relationship exists between civics education and increased civic and political knowledge; however, classroom instruction alone cannot provide all that is needed to promote a community of civic-minded individuals. Further, a survey of state level civics standards acknowledged the important relationship between participatory …

The Core Collapse Supernova Rate In The Sdss-Ii Supernova Survey, Matthew Frederick Taylor Jan 2011

The Core Collapse Supernova Rate In The Sdss-Ii Supernova Survey, Matthew Frederick Taylor

Wayne State University Dissertations

The Sloan Digital Sky Survey II Supernova Survey (SDSS-II SN), though designed as a type Ia supernova search for cosmology, also discovered a large sample of core collapse supernovae (CCSN). I use the SDSS-II SN data to measure the volumetric CCSN rate in the redshift range (0.03 < z < 0.09), finding a volume-averaged rate of 0.98±0.18 ×10⊃−4⊃h⊂70⊂⊃3⊃yr⊃−1⊃Mpc⊃−3⊃. The CCSN luminosity function is also extracted from the data, and its implications on the cosmic star formation history are considered.

A Unified Model-Based Fault Diagnosis Scheme For Nonlinear Discrete-Time Systems With Additive And Multiplicative Faults, Hasan Ferdowsi, Sarangapani Jagannathan Jan 2011

A Unified Model-Based Fault Diagnosis Scheme For Nonlinear Discrete-Time Systems With Additive And Multiplicative Faults, Hasan Ferdowsi, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a novel model-Based fault diagnosis scheme is proposed for a class of uncertain nonlinear discrete-time systems which can be subjected to both additive and multiplicative faults. Faults are detected by using a novel (FD) observer consisting of two online approximators in discrete-time (OLAD) and a robust adaptive term. Upon detection, a fault diagnosis scheme is introduced to determine the fault type by monitoring the input residual generated via the first OLAD output. Then the appropriate OLAD is included in the observer while the other OLAD is switched off. Next, by using both the parameter update law of …

Neural Network-Based Optimal Control For Trajectory Tracking Of A Helicopter Uav, David Nodland, H. Zargarzadeh, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

Helicopter unmanned aerial vehicles (UAVs) may be widely used for both military and civilian operations. Because these helicopters are underactuated nonlinear mechanical systems, high-performance controller design for them presents a challenge. This paper presents an optimal controller design for trajectory tracking of a helicopter UAV using a neural network (NN). the state-feedback control system utilizes the backstepping methodology, employing kinematic and dynamic controllers. the online approximator-Based dynamic controller learns the infinite-horizon Hamilton-Jacobi-Bellman (HJB) equation in continuous time and calculates the corresponding optimal control input to minimize the HJB equation forward-in-time. Optimal tracking is accomplished with a single NN utilized for …

Concept-Driven Multi-Modality Fusion For Video Search, Xiao-Yong Wei, Yu-Gang Jiang, Chong-Wah Ngo Jan 2011

Concept-Driven Multi-Modality Fusion For Video Search, Xiao-Yong Wei, Yu-Gang Jiang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

As it is true for human perception that we gather information from different sources in natural and multi-modality forms, learning from multi-modalities has become an effective scheme for various information retrieval problems. In this paper, we propose a novel multi-modality fusion approach for video search, where the search modalities are derived from a diverse set of knowledge sources, such as text transcript from speech recognition, low-level visual features from video frames, and high-level semantic visual concepts from supervised learning. Since the effectiveness of each search modality greatly depends on specific user queries, prompt determination of the importance of a modality …

Cylinders And Spheres : Toddlers Engage In Problem Solving, Rosemary Geiken Jan 2011

Cylinders And Spheres : Toddlers Engage In Problem Solving, Rosemary Geiken

Dissertations and Theses @ UNI

Every day more six million infants and toddlers (children under 3 years of age) enter some kind of out-of-home care, with 22% of this group attending center-based programs. Studies on the quality of care in centers indicate that 40% of these children are in poor quality settings while 51 % are in mediocre to medium quality settings. Two factors contributing to these low ratings are lack of age-appropriate materials and lack of learning opportunities. To address these data Piaget's theory of constructivism guided the design of a study to provide evidence of construction of knowledge that occurred when toddlers were …

Human Values And The Importance Of Money, Sara Lucia Estrada Villalta Jan 2011

Human Values And The Importance Of Money, Sara Lucia Estrada Villalta

Dissertations and Theses @ UNI

Research has shown that there is relationship between money and an orientation toward self-interest, both at the individual and country-level. However, the causal relationship between these constructs is not fully understood. Based on Schwartz's theory of human values, which distinguishes between self-oriented and socially-oriented values, this study explored whether values have a causal influence on the importance people place on money. Four different sets of values were primed using a scrambled-sentences task to test their effects on the importance participants ascribed to money. Importance of money was measured in three ways: desire for money, relative importance of financial goals, and …

Innovation And Price Competition In A Two-Sided Market, Mei Lin, Shaojin Li, Andrew B. Whinston Jan 2011

Innovation And Price Competition In A Two-Sided Market, Mei Lin, Shaojin Li, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

We examine a platform's optimal two-sided pricing strategy while considering seller-side innovation decisions and price competition. We model the innovation race among sellers in both finite and infinite horizons. In the finite case, we analytically show that the platform's optimal seller-side access fee fully extracts the sellers' surplus, and that the optimal buyer-side access fee mitigates price competition among sellers. The platform's optimal strategy may be to charge or subsidize buyers depending on the degree of variation in the buyers' willingness to pay for quality; this optimal strategy induces full participation on both sides. Furthermore, a wider quality gap among …

Issues And Guidelines In Modeling Decomposition Of Minimum Participation In Entity-Relationship Diagrams, Cecil Eng Huang Chua, Veda C. Storey Jan 2011

Issues And Guidelines In Modeling Decomposition Of Minimum Participation In Entity-Relationship Diagrams, Cecil Eng Huang Chua, Veda C. Storey

Business and Information Technology Faculty Research & Creative Works

The entity-relationship model has long been employed for conceptual modeling of databases. Methodologies and heuristics have been developed, both for effective modeling and for translating entity-relationship models into relational models. One aspect of modeling that is often overlooked in design methodologies is the use of optional versus mandatory participation (i.e., minimum participation) on the development of relational databases. This tutorial complements existing instructional material on database design by analyzing the syntactic implications of minimum participation in binary, unary, and n-ary relationship sets and for the special case where the E-R diagram depicts a database where 3NF is not in BCNF. …

Improving Gene Expression Data Interpretation By Finding Latent Factors That Co-Regulate Gene Modules With Clinical Factors, Tianwei Yu, Yun Bai Jan 2011

Improving Gene Expression Data Interpretation By Finding Latent Factors That Co-Regulate Gene Modules With Clinical Factors, Tianwei Yu, Yun Bai

PCOM Scholarly Works

Background: In the analysis of high-throughput data with a clinical outcome, researchers mostly focus on genes/proteins that show first-order relations with the clinical outcome. While this approach yields biomarkers and biological mechanisms that are easily interpretable, it may miss information that is important to the understanding of disease mechanism and/or treatment response. Here we test the hypothesis that unobserved factors can be mobilized by the living system to coordinate the response to the clinical factors.Results: We developed a computational method named Guided Latent Factor Discovery (GLFD) to identify hidden factors that act in combination with the observed clinical factors to …
