Bioactive Secondary Metabolites Produced By Marine Microorganisms: Their Isolation, Structural Elucidation And Function, Jiayuan Liu

Open Access Master's Theses

Compared to their terrestrial counterparts, marine microorganisms seem to be a relatively unexplored resource for novel bioactive metabolites. This thesis research aimed to discover new bioactive compounds of pharmaceutical value from the secondary metabolites produced by marine bacteria and fungi. The ecological role of marine bacteria involving the production of antibacterial metabolites was also investigated.

This thesis describes three different studies, all of which are focused on the secondary metabolites produced by marine bacteria or fungi. First, bacteria-bacteria antagonism as a mechanism limiting the spread of Vibrio cholerae in the ocean was investigated using a marine particle-attached bacterial model, SWAT3, …

[Un]Safe Harbor: No Common Denominator In Privacy Compliance, Steven A. Wells, Mark Courtney, Peter Vogel

Computer Law Review and Technology Journal

Privacy is a social issue that varies depending on the mores of any particular culture. Clearly there have always been personal privacy issues before the advent of the Internet. However, the Internet has provided widespread proliferation of personal data which has dramatically changed the scope of where personal data may be. It was not really until about 1995 that the Internet brought this wide-spread change caused by ubiquitous growth of personal computers, online networks, graphical browsers, and broadband communications. Since it is impossible to accurately predict the ultimate direction of personal privacy on the Internet, governments around the world are …

Icann May Be The Only Game In Town, But Marina Del Rey Isn't The Only Town On Earth: Some Thoughts On The So-Called "Uniqueness" Of The Internet, Volker Kitz

Computer Law Review and Technology Journal

"If you want to attach your network to the Internet, but you don't like the Network Solution, Inc.'s ("NSI") policies, for whatever reason, you quickly learn that NSI is the only game in town," said Catherine Simmons- Gill at a Congressional hearing in 1996. One might pose the question, "Why not just go to a different town?" Unfortunately, no other "town" can pride itself on hosting an organization that ultimately presides over the assignment of domain names under the current domain name system. The Internet Corporation for Assigned Names and Numbers ("ICANN"), based in Marina del Rey, is presently in …

Jurisdictional Issues In Electronic Commerce Contracts: A Canadian Perspective, Shafik Bhalloo

Computer Law Review and Technology Journal

Governments, the private sector, the media, and academicians have defined electronic commerce ("e-commerce") in a variety ways. Narrowly defined, e-commerce refers to sales or purchases transacted over open or public networks, such as the Internet, independent of whether the payment is made on the network. Employing a broader definition, e-commerce may also include sales and purchases made over closed or private networks, such as electronic data interchange ("EDI") and debit or credit cards.' This article will focus on the narrower definition of e-commerce and, more specifically, business-to-consumer ("B-to-C") transactions rather than business-to-business ("B-to-B") transactions.

In the first part of this …

Entrepreneurial Open Source Software Hackers: Mysql And Its Dual Licensing, Robert W. Gomulkiewicz

Computer Law Review and Technology Journal

Hackers often quibble about commercializing software, yet most will readily sell their programming services. Richard Stallman, the father of free software, has always recognized that hackers have a right to make money. Aside from selling programming services, however, Stallman's disciples seem to frown upon commercializing software. Other hackers, labeling themselves "open source" developers, have warmed to the possibility that free software may be profitable.

This article describes one of the most promising business models for hackers, called "dual licensing." In this model, hackers offer the same code under two different licenses: a commercial license and an open source license. Licensees …

Race And Representation In Congress: The Color Of Constituencies, John Larson '06

Res Publica - Journal of Undergraduate Research

The topic of race, redistricting, and minority representation in Congress has emerged as one of the most salient issues in contemporary political thought. The creation of so‑called majority minority districts has been attacked as unfair and racially polarizing by some observers and ultimately struck down as unconstitutional by the Supreme Court. The study of race in relation to American politics and institutions, and, in particular, to the institution of Congress, has produced a wealth of research and literature in recent years. This scope of budding research ranges from legislative activity and Congressional voting to the electoral process and campaigning. This …

The Sibling Study: How Does Having A Sibling With A Mental Disorder Affect The Lives Of College Students, Anna Czipri '04

Honors Projects

Although there are many positive outcomes of growing up with a sibling having a psychological or behavioral disorder, typical siblings can potentially experience harmful effects of managing and coping with the special demands and stresses of having a sibling with these kinds of difficulties. The college years are often a time to restructure sibling relationships. It is a time when young adults experience what it is like to be away from home for the first time, develop new groups of friends, and start new behavior patterns, attitudes, goals, and relationships that call for a more mature individual. The current study …

User Authentication And Supervision In Networked Systems, Paul Steven Dowland

School of Engineering, Computing and Mathematics Theses

This thesis considers the problem of user authentication and supervision in networked systems. The issue of user authentication is one of on-going concern in modem IT systems with the increased use of computer systems to store and provide access to sensitive information resources. While the traditional username/password login combination can be used to protect access to resources (when used appropriately), users often compromise the security that these methods can provide. While alternative (and often more secure) systems are available, these alternatives usually require expensive hardware to be purchased and integrated into IT systems. Even if alternatives are available (and financially …

Organizational Forming In Amodern Times: Reinserting The Dynamic Into The Organizational, Paul Donnelly

Conference papers

While there is an obvious concern that “new organizational forms” are appearing, and despite the topic receiving increased attention, scholars, as yet, have been unable to theorize, grasp or account for these new forms adequately. In continuing to look for the ‘new’ with ‘old’ lenses, we are seeing neither real departure from Weberian conceptualizations other than oppositional approaches still in search of an essential entity, nor much consideration given to the possibility that the paradigmatic approach to form is also part of the problem. In light of this, I posit that thinking within a modernist epistemological framework has served to …

Affordance, Attention And Laterality, Lari Vainio

School of Psychology Theses

This thesis examines object-guided actions. Recently, micro-affordance effects have shown that a visual object affords actions automatically. These effects are observed when the grasp type (precision and power grasp) is facilitated by size (small and large) of the categorized object (the object-size effect), or when right or left hand responses are facilitated by object orientation (the object-orientation effect). It has been shown elsewhere that attentional mechanisms have a vital role in visually guided movements. In addition, visually guided movements have associated with hemispheric lateralization. Thus, the central focus of the thesis was the role of different components of attention (location-based-, …

Advanced User Authentification For Mobile Devices, Nathan Clarke

School of Engineering, Computing and Mathematics Theses

Recent years have witnessed widespread adoption of mobile devices. Whereas initial popularity was driven by voice telephony services, capabilities are now broadening to allow an increasing range of data orientated services. Such services serve to extend the range of sensitive data accessible through such devices and will in turn increase the requirement for reliable authentication of users. This thesis considers the authentication requirements of mobile devices and proposes novel mechanisms to improve upon the current state of the art. The investigation begins with an examination of existing authentication techniques, and illustrates a wide range of drawbacks. A survey of end-users …

Stroke In Devon: Knowledge Was Good, But Action Was Poor., C. Carroll, J. Hobart, C. Fox, L. Teare, J. Gibson

Peninsula Medical School

BACKGROUND AND AIM: Effective implementation of early treatment strategies for stroke requires prompt admission to hospital. There are several reasons for delayed admission. Good awareness should facilitate early admission. We identified local targets for education. METHODS: Four groups, each of 40 people, completed questionnaires to determine their knowledge of stroke symptoms and risk factors, and the action they took or would take in the event of a stroke. The groups were: patients with a diagnosis of stroke or TIA (within 48 hrs of admission); patients at risk of stroke; the general population; and nurses. RESULTS: Forty per cent of stroke …

Deconstructing The Tower Of London : Resolution, Alternatives And Executive Function, Hassina Carder-Gilbert

School of Psychology Theses

Although widely employed as an executive task, the performance demands of the Tower of London task (TOL) are not well understood. The aim of this Thesis is to determine what TOL measures and seven studies are included that illustrate its performance demands. Much of the work is experimental and TOL is explored via a novel verification paradigm in which participants make speeded judgements about whether a demonstrated move is optimal or suboptimal. The deconstruction of the task to the level of the individual move indicated that the number of moves until a disk was placed in its goal position (resolution) …

Vision-Based Urban Navigation Procedures For Verbally Instructed Robots, Theocharis Kyriacou

School of Engineering, Computing and Mathematics Theses

The work presented in this thesis is part of a project in instruction based learning (IBL) for mobile robots were a robot is designed that can be instructed by its users through unconstrained natural language. The robot uses vision guidance to follow route instructions in a miniature town model. The aim of the work presented here was to determine the functional vocabulary of the robot in the form of "primitive procedures". In contrast to previous work in the field of instructable robots this was done following a "user-centred" approach were the main concern was to create primitive procedures that can …

Integrating Perception, Language And Problem Solving In A Cognitive Agent For A Mobile Robot., Deryle W. Lonsdale, D. Paul Benjamin, Damian M. Lyons

Faculty Publications

We are implementing a unified cognitive architecture for a mobile robot. Our goal is to endow a robot agent with the full range of cognitive abilities, including perception, use of natural language, learning and the ability to solve complex problems. The perspective of this work is that an architecture based on a unified theory of robot cognition has the best chance of attaining human-level performance.

This agent architecture is an integration of three theories: a theory of cognition embodied in the Soar system, the RS formal model of sensorimotor activity and an algebraic theory of decomposition and reformulation.

These three …

Ten Efficient Research Strategies For Distance Learning, Thomas C. Wright, Scott L. Howell

Faculty Publications

Today's distance education administrator, frequently with an expertise in another academic discipline, is also supposed to be a distance education scholar. This expectation results from the recent interest in distance learning that nearly all institutions of learning and disciplines of study have shown. More research, studies, journals, and essays about distance education also exist than at any other time.

A distance education administrator and an education research librarian at Brigham Young University have teamed up to identify ten pragmatic research strategies to help new, busy, and even a few experienced distance education administrators stay current in their field and successful …

Liquid Crystal Based Optical Switches, Yuliya Semenova, S. Dovgalets, Yuri Panarin, Gerald Farrell

Articles

Optical switches using two electro-optical effects in liquid crystals are proposed and investigated for incorporation in a switch matrix for optical networks. These two devices employ selective reflection in cholesteric layers and total reflection at the border between glass and nematic liquid crystal. Prototypes of these switches have been designed and their parameters have been investigated. Initial results suggest the switching contrast ratio of 38.5 and 42 dB, respectively, with insertion loss about 2.3…2.9 dB for polarized light.

Optimal Control Strategy Of Upqc For Minimum Operational Losses, Malabika Basu, Michael Farrell, Michael Conlon, Kevin Gaughan, Eugene Coyle

Conference papers

The paper deals with a new control technique for a unified power quality conditioner (UPQC), which is the most comprehensive of FACTS devices. The problems of power quality continue to gain in significance because of the proliferation of sensitive and harmonic producing loads in electrical networks. Greater awareness among customers with regard to supply integrity and a desire by suppliers to be able to guarantee a certain degree of power quality to customers is being reflected in the development of innovative power quality solutions. The UPQC, which is a combination of shunt and series compensation, is designed to cater for …

Remembering The Forgotten Ones: Protecting The Elderly From Financial Abuse

San Diego Law Review

There is nothing new about fraudulently taking money from people, particularly the elderly. The elderly population is rapidly increasing, however, and is readily accessible by telephone and mail. As a result, the elderly are easy targets for financial abuse. Such abuse can emanate from several sources, including people the victims know and trust, particularly family and friends.

Perpetrators can be people upon whom the elderly depend for care. Abuse can also come from strangers with whom elderly victims have no direct contact. This Article focuses primarily on the financial abuse of the elderly by strangers.

The Deferred Action Program Of The Bureau Of Citizenship And Immigration Services: A Possible Remedy For Impossible Immigration Cases

San Diego Law Review

This beneficent operations instruction permitted two alternative interpretations, each of which was taken up by the federal courts. In the case of Nicholas v. INS, the petitioner asked the Ninth Circuit Court of Appeals to overrule the district director’s decision to deny his nonpriority status application. The court determined that the operations instruction confers a “substantive benefit upon the alien, rather than setting up an administrative convenience,”and thus is essentially a legislative rule requiring a strict standard of application, and not one allowing the INS a significant amount of discretion. The Fifth Circuit held in Soon Bok Yoon v. INS …

Can Promise Enforcement Save Affordable Housing In The United States?

San Diego Law Review

Promise Enforcement is my original approach to the development of affordable housing. Promise Enforcement, as a system, includes three components: (1) contextual thinking; (2) valuing individuality, and (3) comprehensive responsibility. Contextual thinking involves a sense of environmental, historical, and geographic context. Valuing individuality allows residents of public housing to express themselves as unique individuals. Comprehensive responsibility involves a complete understanding of the costs and benefits of affordable housing. The theory was inspired in part by the work of Austrian activist, artist, and architect Friedensreich Hundertwasser and the writings of French social contract theorist Jean-Jacques Rousseau. My article that introduced the …

Likelihood Of Confusion

San Diego Law Review

The primary objective of this Article is to illustrate the tendency of judges to inappropriately rely on personal intuition and subjective, internalized stereotypes when ruling on trademark disputes. Where jurists perceive consumers as ludicrously easily confused, trademark holders can exploit these views to secure broad trademark “rights,” often without offering a shred of evidentiary corroboration concerning such confusion. As a consequence, the proof required to support allegations that a trademark usage creates a likelihood of confusion is potentially lessened in all cases, making trademarks normatively stronger, broader, and ever easier to “protect” for mark holders. Whether consumers realistically benefit from …

In The Wake Of Enzo: The Impact Of The Federal Circuit’S Decision On The U.S. Life Science Industry

San Diego Law Review

The United States spends more on health care than any other country in the world.The U.S. Patent and Trademark Office (PTO) helps drive health care costs higher by awarding monopolies to scientific researchers whose inventions meet the requirements dictated by Title 35 of the U.S. Code.3 Once the PTO awards such a monopoly, the inventor is the only party legally entitled to make, use, or sell the invention in the United States. Though monopolies are thought to impair competition, under the U.S. system these exclusionary rights are the rewards an inventor earns in exchange for enriching the pool of publicly …

Obstructing Justice: The Rise And Fall Of The Aedpa

San Diego Law Review

From 1994 through as late as August 2001, the United States intelligence community1

received information that terrorists had seriously contemplated using airplanes as instruments for carrying out international terrorist attacks.2

This method of attack was clearly “discussed in terrorist circles,” yet community analysts demonstrated little effort to strategically counter such terrorist groups. Moreover, in 1998, U.S. intelligence received specific information that “a group of unidentified Arabs planned to fly an explosive-laden plane from a foreign country into the World Trade Center.” In July 2001, senior government officials were warned of “a significant terrorist attack against U.S. and/or Israeli interests in …

A Randomised Controlled Trial And Cost Effectiveness Study Of Systematic Screening (Targeted And Total Population Screening) Versus Routine Practice For The Detection Of Atrial Fibrillation In The Over 65s: (Safe) [Isrctn19633732], Dawn Swancutt, Richard Hobbs, David Fitzmaurice, Jonathan Mant, Ellen Murray, Sue Jowett, James Raftery, Stirling Bryan, Michael Davies, Gregory Lip

Peninsula Medical School

Background Atrial fibrillation (AF) has been recognised as an important independent risk factor for thromboembolic disease, particularly stroke for which it provides a five-fold increase in risk. This study aimed to determine the baseline prevalence and the incidence of AF based on a variety of screening strategies and in doing so to evaluate the incremental cost-effectiveness of different screening strategies, including targeted or whole population screening, compared with routine clinical practice, for detection of AF in people aged 65 and over. The value of clinical assessment and echocardiography as additional methods of risk stratification for thromboembolic disease in patients with …
