Inter-Tube Bonding And Defects In Carbon Nanotubes And The Impact On The Transport Properties And Micro-Morphology, Keqin Yang Dec 2009

Inter-Tube Bonding And Defects In Carbon Nanotubes And The Impact On The Transport Properties And Micro-Morphology, Keqin Yang

All Dissertations

The transport properties of the carbon nanotubes (CNTs) are affected by the tube-tube interaction and the defects presented in the system. Inter-tube bonding, formed during spark plasma sintering (SPS) process, lowers the electrical/thermal resistivity at the tube-tube junctions and also causes new scattering mechanisms such as strong electron-phonon coupling (EPC) at low temperature. More evidences have been found by changing the SPS temperature and doping the CNTs to support the electron-phonon coupling is Kohn anomaly (KA) in as-SPSed CNTs. The phonon drag, appearing in thermoelectric power (TEP) of the as-SPSed CNTs at low temperature, can be explained in the framework …

Characterization Of Escherichia Coli Related To Construction Site Sediment Basins, Calvin Sawyer Dec 2009

Characterization Of Escherichia Coli Related To Construction Site Sediment Basins, Calvin Sawyer

All Dissertations

Large construction sites can have significant temporary and permanent impacts on the physical landscape. Excess sediment is frequently deposited into nearby surface waters, altering benthic habitat, reducing water clarity and transporting other pollutants such as enteric bacteria. To capture eroded soil and attenuate storm discharge peaks, many permitted construction projects larger than 10 acres in South Carolina require the installation of a sediment basin. Sediment-laden runoff is routed to a newly excavated impoundment, where larger particles settle out of suspension. Thus an entirely new hydrologic feature designed to concentrate eroded sediment and water is introduced into the landscape.
Eight construction …

‘Motivation In Action’ In A Collaborative Primary Classroom: Developing And Sustaining Teacher Motivation, Veronica Morcom, Judith Maccallum Dec 2009

‘Motivation In Action’ In A Collaborative Primary Classroom: Developing And Sustaining Teacher Motivation, Veronica Morcom, Judith Maccallum

Australian Journal of Teacher Education

This paper examines how the process of scaffolding students to solve their social issues developed mature participation for both the teacher and students. A sociocultural perspective framed the research as the underlying assumption is that students learn from each other, mediated by the teacher or more capable peers. The study provides evidence that teachers play a significant role in mediating positive relationships amongst peers, which in this case, sustained the teacher’s motivation to engage in the challenging and at times exhausting process. The teacher used weekly class meetings to negotiate with students how to share ‘power’ and model democratic decision-making. …

Configuring Of Masculinity In An Ethnocentric Community School, Dimitri Garas, Sally Godinho Dec 2009

Configuring Of Masculinity In An Ethnocentric Community School, Dimitri Garas, Sally Godinho

Australian Journal of Teacher Education

This paper presents snapshots of a qualitative study that investigated how Year 8 boys in an ethnocentric community school configured their constructions of masculinity. Fifteen boys participated in focus group discussions that extended over a six-week period. For one focus group, the boys were invited to bring a ‘totem’, which was an embodiment of their masculinity. The findings from the focus groups revealed both collective and individual constructions and enactments of masculinities that were talked into existence and transmitted through hegemonic discourses. Yet the findings also revealed the boys’ individual agency to engage with other ways of doing and being …

Teaching Out-Of-Field In Western Australia, Andrew Mcconney, Anne Price Dec 2009

Teaching Out-Of-Field In Western Australia, Andrew Mcconney, Anne Price

Australian Journal of Teacher Education

A former head of the American Federation of Teachers, Albert Shanker, once called out-of-field teaching education’s “dirty little secret” (Ingersoll, 2003, p. 5). The practice of allowing or assigning teachers to teach subjects or year levels for which they do not have any formal qualifications has lead to considerable debate within the educational community. Such concerns over the possible negative impact of out-of-field teaching on students, teachers and the broader school community led the Western Australian College of Teaching (WACOT) to commission an exploratory empirical study of the extent of the phenomenon in Western Australia. This paper presents the main …

Feeling Comfortable With Pluralistic Diversity: Using Common Organizational Strategies To Get Uncommon Results In Higher Education Voluntary Service Organizations, Ruth Sessler Bernstein Dec 2009

Feeling Comfortable With Pluralistic Diversity: Using Common Organizational Strategies To Get Uncommon Results In Higher Education Voluntary Service Organizations, Ruth Sessler Bernstein

Student Scholarship

Diversity is a goal of the majority of America's institutions of higher learning. These colleges and universities have made great strides in achieving representational diversity through aggressive recruiting and retention efforts. However, on campus, students infrequently engage in pluralistic diversity. This paper examines a national voluntary service organization at two pluralistically diverse universities. Semi-structured interviews with members and alumni of the association provided insight into the characteristics of the interactions they have had with those who are different from them. These insights enabled us to examine the specific organizational strategies this nonprofit adopted that promoted enriching intercultural interactions.

Teacher Leadership Practices In Large Texas High Schools With Different Accountability Ratings: A Mixed Methods Study, Cynthia Molina Saldivar Dec 2009

Teacher Leadership Practices In Large Texas High Schools With Different Accountability Ratings: A Mixed Methods Study, Cynthia Molina Saldivar

Theses and Dissertations - UTB/UTPA

A promising strategy for improving education is to use the energy of teacher leaders as agents of school change. According to Katzenmeyer and Moller (2001), teaching and learning improve where shared leadership exists, and when there is no expectation of “heroic leadership” from one person. Therefore, this mixed methods study was designed to examine teacher leadership and the leadership styles and practices of principals in large Texas high schools with different accountability ratings. Two hundred and fifteen participants consisting of teachers, teacher leaders, and leadership team members from 24 high schools were surveyed; and personal interviews were held with principals …

Open For Learning: The Cms And The Open Learning Network, Jon Mott, David Wiley Dec 2009

Open For Learning: The Cms And The Open Learning Network, Jon Mott, David Wiley

Faculty Publications

The course management system (CMS) reinforces the status quo and hinders substantial teaching and learning innovation in higher education. It does so by imposing artificial time limits on learner access to course content and other learners, privileging the role of the instructor at the expense of the learner, and limiting the power of the network effect in the learning process. The open learning network (OLN)—a hybrid of the CMS and the personal learning environment (PLE)—is proposed as an alternative learning technology environment with the potential to leverage the affordances of the Web to dramatically improve learning.

Gpu-Accelerated Hierarchical Dense Correspondence For Real-Time Aerial Video Processing, Stephen Cluff, Bryan S. Morse, Jonathan D. Cohen, Mark Duchaineau Dec 2009

Gpu-Accelerated Hierarchical Dense Correspondence For Real-Time Aerial Video Processing, Stephen Cluff, Bryan S. Morse, Jonathan D. Cohen, Mark Duchaineau

Faculty Publications

Video from aerial surveillance can provide a rich source of data for many applications and can be enhanced for display and analysis through such methods as mosaic construction, super-resolution, and mover detection. All of these methods require accurate frame-to-frame registration, which for live use must be performed in real time. In many situations, scene parallax may make alignment using global transformations impossible or error-prone, limiting the performance of subsequent processing and applications. For these cases, dense (per-pixel) correspondence is required, but this can be computationally prohibitive. This paper presents a hierarchical dense correspondence algorithm designed for implementation on graphics processing …

Biological Diversity Of Prokaryotic Type Iv Secretion Systems, Cristina E Alvarez-Martinez, Peter J Christie Dec 2009

Biological Diversity Of Prokaryotic Type Iv Secretion Systems, Cristina E Alvarez-Martinez, Peter J Christie

Faculty, Staff and Student Publications

Type IV secretion systems (T4SS) translocate DNA and protein substrates across prokaryotic cell envelopes generally by a mechanism requiring direct contact with a target cell. Three types of T4SS have been described: (i) conjugation systems, operationally defined as machines that translocate DNA substrates intercellularly by a contact-dependent process; (ii) effector translocator systems, functioning to deliver proteins or other macromolecules to eukaryotic target cells; and (iii) DNA release/uptake systems, which translocate DNA to or from the extracellular milieu. Studies of a few paradigmatic systems, notably the conjugation systems of plasmids F, R388, RP4, and pKM101 and the Agrobacterium tumefaciens VirB/VirD4 system, …

Protein Secondary Structure Prediction Using Parallelized Rule Induction From Coverings, Leong Lee, Cyriac Kandoth, Jennifer Leopold, Ronald L. Frank Dec 2009

Protein Secondary Structure Prediction Using Parallelized Rule Induction From Coverings, Leong Lee, Cyriac Kandoth, Jennifer Leopold, Ronald L. Frank

Computer Science Faculty Research & Creative Works

Protein 3D structure prediction has always been an important research area in bioinformatics. In particular, the prediction of secondary structure has been a well-studied research topic. Despite the recent breakthrough of combining multiple sequence alignment information and artificial intelligence algorithms to predict protein secondary structure, the Q3 accuracy of various computational prediction algorithms rarely has exceeded 75%. In a previous paper [1], this research team presented a rule-based method called RT-RICO (Relaxed Threshold Rule Induction from Coverings) to predict protein secondary structure. The average Q3 accuracy on the sample datasets using RT-RICO was 80.3%, an improvement over comparable computational methods. …

Enabling Secure Secret Updating For Unidirectional Key Distribution In Rfid-Enabled Supply Chains, Shaoying Cai, Tieyan Li, Changshe Ma, Yingjiu Li, Robert H. Deng Dec 2009

Enabling Secure Secret Updating For Unidirectional Key Distribution In Rfid-Enabled Supply Chains, Shaoying Cai, Tieyan Li, Changshe Ma, Yingjiu Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

In USENIX Security 08, Juels, Pappu and Parno proposed a secret sharing based mechanism to alleviate the key distribution problem in RFID-enabled supply chains. Compared to existing pseudonym based RFID protocols, the secret sharing based solution is more suitable for RFID-enabled supply chains since it does not require a database of keys be distributed among supply chain parties for secure ownership transfer of RFID tags. However, this mechanism cannot resist tag tracking and tag counterfeiting attacks in supply chain systems. It is also not convenient for downstream supply chain parties to adjust the size of RFID tag collections in recovering …

Computationally Secure Hierarchical Self-Healing Key Distribution For Heterogeneous Wireless Sensor Networks, Yanjiang Yang, Jianying Zhou, Robert H. Deng, Feng Bao Dec 2009

Computationally Secure Hierarchical Self-Healing Key Distribution For Heterogeneous Wireless Sensor Networks, Yanjiang Yang, Jianying Zhou, Robert H. Deng, Feng Bao

Research Collection School Of Computing and Information Systems

Self-healing group key distribution is a primitive aimed to achieve robust key distribution in wireless sensor networks (WSNs) over lossy communication channels. However, all the existing self-healing group key distribution schemes in the literature are designed for homogenous WSNs that do not scale. In contract, heterogeneous WSNs have better scalability and performance. We are thus motivated to study self-healing group key distribution for heterogeneous WSNs. In particular, we propose the concept of hierarchical self-healing group key distribution, tailored to the heterogeneous WSN architecture; we further revisit and adapt Dutta et al.’s model to the setting of hierarchical self-healing group …
