Teachers' Perceptions Of Administrative Leadership Styles And Schools As Professional Learning Communities, Clive Coleman May 2005

Teachers' Perceptions Of Administrative Leadership Styles And Schools As Professional Learning Communities, Clive Coleman

LSU New Orleans Theses and Dissertations

This study examined the relationship of principal and assistant principal leadership style in shaping teachers' perceptions of their schools as professional learning communities. The researcher proposed that the traditional distinctions between the classic modes of leadership, namely, transactional and transformational modes of leadership, are difficult to interpret within the framework of professional learning community without considering the interaction of the principal and assistant principal leadership roles. Using Leithwood's (1992, 1993, 1994) definitions of leadership as transformational and management as transactional, empirical evidence from 81 schools is presented that supports the need for both leadership and management skills in the development …

Three Factor Authentication Using Java Ring And Biometrics, Jyothi Chitiprolu

LSU New Orleans Theses and Dissertations

Computer security is a growing field in the IT industry. One of the important aspects of the computer security is authentication. Using passwords (something you know) is one of the most common ways of authentications. But passwords have proven to provide weak level of security as they can be easily compromised. Some other ways of authenticating a user are using physical tokens, (something you possess) and biometrics, (something you are). Using any one of these techniques to secure a system always has its own set of threats. One way to make sure a system is secure is to use multiple …

A Personnel-Driven Mini Assessment Approach For Supporting Continuous System And Software Process Improvement, Lee Mckinney Dec 2004

A Personnel-Driven Mini Assessment Approach For Supporting Continuous System And Software Process Improvement, Lee Mckinney

LSU New Orleans Theses and Dissertations

Assessments are fundamental to the process improvement program of any organization in the software industry. Assessments provide a view of the state, capability, and maturity of processes in an organization relative to a reference model. Formal assessments are the most recognized, and are comprehensive in nature. Although the depth of their evaluation often results in significant process improvement opportunities, formal assessments are too costly for frequent use by many organizations. The interim between assessments typically leaves these organizations without the currency of process state information necessary to effectively drive continuous process improvement. Mini-assessments have emerged as a solution. This paper …

Development And Characterization Of Controlled Drug Delivery Using Nanoparticles, Li Chen Dec 2004

Development And Characterization Of Controlled Drug Delivery Using Nanoparticles, Li Chen

LSU New Orleans Theses and Dissertations

The objective of this project was to develop new controlled drug delivery systems using nanomeric particles and characterize the delivery of drugs into cells in real time by digital fluorescence imaging microscopy techniques. The project is based on the idea that it could be possible to improve efficacy of drug molecules when encapsulated in nanometer-sized particles. Due to their small dimensions the particles could permeate through cells and tissues and even through the blood brain barrier. The anti-cancer drug Doxorubicin was encapsulated into biodegradable Poly (DL-lactideco- glycolide) (PLGA) nanoparticles by simple nanoprecipitation method. The small size of these particles (<200nm) could be beneficial to realize passive tumor-targeted drug delivery through enhanced permeability and retention (EPR) effects. These drug-containing particles showed a sustained release profile. Fluorescence images indicated that these particles can be internalized by human breast cancer MCF-7 cells by non-specific endocytosis. The bioactivity of the drugs was also tested against cell culture. The results indicated that DXR-loaded PLGA nanoaprticles could be used to deliver Doxorubicin into breast cancer cells.
