Stage Profiles And Predictors Of Exercise In A Multiple Risk Sample, Gabriela Dye

Open Access Dissertations

Cluster and Latent class analyses were used to examine within Stage profiles of individuals at-risk for three behaviors based on their perceived Pros, Cons, and Self-efficacy. In addition, Structural equation and Latent variable modeling were used to examine the predictors of 12 months exercise participation. The results of Cluster and Latent class analyses did not replicate the results of previous studies, which delineated at least four distinct profiles within the Stages. Only two to three profiles emerged within each Stage as well as within the full dataset. Most two-cluster/class, and three-cluster/class solutions consisted of at least one cluster with extremely …

Rescheduling Point Determination In Dynamic Fms Using A Flexiblility Metric Methodology, Pejman Hassanzadeh Mostafai

Open Access Dissertations

In production environments, such as Flexible Manufacturing Systems (FMS), the production schedule can be disturbed by the occurrence of unplanned events. Machines stop due to failures, maintenance, tool changes due to wear, or tool reassignments. Because of the changing nature of an FMS, a global and static schedule created at time zero can only provide a rough guideline for the control activity. The rescheduling process, however, can be costly and time consuming. An updated schedule may require new tool assignments with more setup time. Hence, ideal rescheduling frequency is another unknown factor. In dynamic production environments, like FMS, selecting fixed …

Graph Coloring Algorithms For Tdma Scheduling In Wireless Sensor Networks, Tiegeng Ren

Open Access Dissertations

Since these Micro-Electro-Mechanical systems (MEMS) are constrained by power, physical size, and wireless communication range, efficient use of the technique leaves many challenges for researchers. One of the challenges comes from the medium access control (MAC), which determines the physical and network layer communication model within the network. In this research, we focus on MAC protocol, investigate into the mathematical model of the MAC protocols in graph theory, and develop the following algorithms that would improve the performance of data delivery applications …

Physical And Mechanical Properties Of Model Asphalt Systems Calculated Using Molecular Simulation, Liqun Zhang

Open Access Dissertations

Asphalt is a complex system. Based on solubility parameters, asphalt was classified into asphaltene, resin, and maltene. Using several compounds to represent each part and keeping carbon:hydrogen ratio and other elementary compositions close to real asphalts, three model asphalt systems were built for molecular simulations. Density, heat capacity, isothermal compressibility, thermal expansion coefficient, and bulk modulus were calculated at different temperatures. Glass transition temperature was analyzed based on physical property temperature dependence. Microstructures within model asphalt systems were calculated. Analyzing radial distribution functions between asphaltene and resin molecules and between asphaltene molecules, asphaltene aggregates and depletion of resin molecules surrounding …

Air-Sea Scalar Flux Due To Wind-Generated Near-Surface Turbulent Eddies: The Eddy Renewal Model, Eric G. Van Inwegen

Open Access Master's Theses

Based on analyses of infrared images of the air-water interface, a new model of surface tracer flux is presented (eddy renewal model). In contrast to the currently used model (surface renewal model), which assumes that water motions are driven solely by breaking event-like conditions (or sudden bursts of turbulence), the new model posits that water motions are driven by Langmuir-like turbulent eddies (or more steady-state conditions). These wind-generated turbulent eddies arrange to create elongated warm patches of upwelled water between long streaks of colder downwelling water. In analyzing the images taken during GasEx2001 expedition in 2001 in the Equatorial Pacific …

Solid-State Plasticizers For Melt Extrusion, Dipen Desai

Open Access Dissertations

The hot melt extrusion (HME) is a novel technology to prepare pharmaceutical dosage forms by embedding a drug in a polymer while shaping the composite material to form a pharmaceutical product. The use of polymeric carriers generally requires the incorporation of a plasticizer into the formulation to improve the processing conditions of certain high molecular weight polymers. With liquid plasticizers, non uniform mixing, unstable mass flow, loss and evaporation of plasticizers during high temperature processing may lead to variable process and product performance. To overcome the shortcomings of liquid plasticizers, it is important to evaluate solid-state plasticizers as HME processing …

Women In Mathematics: Motivating Factors For Doctorates In Academia Versus Professionals In The Actuarial Sciences, Diane Elizabeth Hendrix

All Volumes (2001-2008)

The topic under investigation is women in math-related careers and the motivating factors. Two careers, college professors and actuaries, were selected from the many math-related careers because both require advanced studies in mathematics. They also provide a contrast: one is in the business world while the other is in the world of academia. The purpose of this research is to determine if the numbers of women in upper level mathematics and these two careers are increasing. To accomplish this we first analyze women’s enrollment in mathematical programs from high school through graduate school from 1965-1995 in order to assess the …

Neurobiology Meets Social Psychology: An Explanation Of Feminists’ Attitudes Toward Abuse, Christen D. Hazlett

All Volumes (2001-2008)

Why might traumatic events during childhood, such as child abuse, be related to strong identification with more radical feminist beliefs? One explanation may lie in the changes in morphology and physiology of the brain in individuals with a history of child abuse. These changes in the limbic system specifically may influence cognition, affect, and behaviors that are consistent with radical feminist ideology.

The Common Body Of Knowledge: A Framework To Promote Relevant Information Security Research, Kenneth J. Knapp, F. N. Ford, Thomas E. Marshall, R. K. Rainer

Journal of Digital Forensics, Security and Law

This study proposes using an established common body of knowledge (CBK) as one means of organizing information security literature. Consistent with calls for more relevant information systems (IS) research, this industrydeveloped framework can motivate future research towards topics that are important to the security practitioner. In this review, forty-eight articles from ten IS journals from 1995 to 2004 are selected and cross-referenced to the ten domains of the information security CBK. Further, we distinguish articles as empirical research, frameworks, or tutorials. Generally, this study identified a need for additional empirical research in every CBK domain including topics related to legal …

The tool was used to perform the creation and extraction of created information in order to allow the analysis of the non-volatile storage locations …

Information Governance: A Model For Security In Medical Practice, Patricia A. Williams

Journal of Digital Forensics, Security and Law

Information governance is becoming an important aspect of organisational accountability. In consideration that information is an integral asset of most organisations, the protection of this asset will increasingly rely on organisational capabilities in security. In the medical arena this information is primarily sensitive patient-based information. Previous research has shown that application of security measures is a low priority for primary care medical practice and that awareness of the risks are seriously underestimated. Consequently, information security governance will be a key issue for medical practice in the future. Information security governance is a relatively new term and there is little existing …

A Grounded Theory Approach To Identifying And Measuring Forensic Data Acquisition Tasks, Gregory H. Carlton

Journal of Digital Forensics, Security and Law

As a relatively new field of study, little empirical research has been conducted pertaining to computer forensics. This lack of empirical research contributes to problems for practitioners and academics alike.

For the community of practitioners, problems arise from the dilemma of applying scientific methods to legal matters based on anecdotal training methods, and the academic community is hampered by a lack of theory in this evolving field. A research study utilizing a multi-method approach to identify and measure tasks practitioners perform during forensic data acquisitions and lay a foundation for academic theory development was conducted in 2006 in conjunction with …

The past few years have seen activities in the legislative arena covering issues such as digital signatures, the international recognition of electronic documents and privacy and data protection. Both the developed and developing countries have exhibited keenness to embrace the IT environment. Securing this electronic environment from intrusion, however, continues to be problematic. A particular favorite form of computer crime would be ‘hacking’. As more computer systems move on to on-line processing and improved telecommunications, computer hackers are now a real …

Monitoring And Surveillance In The Workplace: Lessons Learnt? – Investigating The International Legal Position, Verine Etsebeth

Journal of Digital Forensics, Security and Law

When considering the legal implications of monitoring and surveillance in the workplace, the question may be asked why companies deploy computer surveillance and monitoring in the first place. Several reasons may be put forward to justify why more than 80% of all major American firms monitor employee e-mails and Internet usage. However, what most companies forget is the fact that the absence or presence of monitoring and surveillance activities in a company holds serious legal consequences for companies. From the discussion in this paper it will become apparent that there is a vast difference in how most countries approach this …

The Evolution Of Internet Legal Regulation In Addressing Crime And Terrorism, Murdoch Watney

Journal of Digital Forensics, Security and Law

Internet regulation has evolved from self-regulation to the criminalization of conduct to state control of information available, accessed and submitted. Criticism has been leveled at the different forms of state control and the methods employed to enforce state control. After the terrorist attack on the USA on 11 September 2001, governments justify Internet state control as a law enforcement and national security tool against the abuse and misuse of the Internet for the commission of serious crimes, such as phishing, child pornography; terrorism and copyright infringement. Some Internet users and civil rights groups perceive state control as an abomination which …

An Exploratory Analysis Of Computer Mediated Communications On Cyberstalking Severity, Stephen D. Barnes, David P. Biros

Journal of Digital Forensics, Security and Law

The interaction between disjunctive interpersonal relationships, those where the parties to the relationship disagree on the goals of the relationship, and the use of computer mediated communications channels is a relatively unexplored domain. Bargh (2002) suggests that CMC channels can amplify the development of interpersonal relationships, and notes that the effect is not constant across communications activities. This proposal suggests a line of research that explores the interaction between computer mediated communications (CMC) and stalking, which is a common form of disjunctive relationships. Field data from cyberstalking cases will be used to look at the effects of CMC channels on …

Providing A Foundation For Analysis Of Volatile Data Stores, Timothy Vidas

Journal of Digital Forensics, Security and Law

Current threats against typical computer systems demonstrate a need for forensic analysis of memory-resident data in addition to the conventional static analysis common today. Certain attacks and types of malware exist solely in memory and leave little or no evidentiary information on nonvolatile stores such as a hard disk drive. The desire to preserve system state at the time of response may even warrant memory acquisition independent of perceived threats and the ability to analyze the acquired duplicate.

Tools capable of duplicating various types of volatile data stores are becoming widely available. Once the data store has been duplicated, current …

Investigating Information Structure Of Phishing Emails Based On Persuasive Communication Perspective, Ki J. Lee, Il-Yeol Song

Journal of Digital Forensics, Security and Law

Current approaches of phishing filters depend on classifying messages based on textually discernable features such as IP-based URLs or domain names as those features that can be easily extracted from a given phishing message. However, in the same sense, those easily perceptible features can be easily manipulated by sophisticated phishers. Therefore, it is important that universal patterns of phishing messages should be identified for feature extraction to serve as a basis for text classification. In this paper, we demonstrate that user perception regarding phishing message can be identified in central and peripheral routes of information processing. We also present a …

Education Organization Baseline Control Protection And Trusted Level Security, Wasim A. Al-Hamdani

Journal of Digital Forensics, Security and Law

Many education organizations have adopted for security the enterprise best practices for implementation on their campuses, while others focus on ISO Standard (or/and) the National Institution of Standards and Technology.

All these adoptions are dependent on IT personal and their experiences or knowledge of the standard. On top of this is the size of the education organizations. The larger the population in an education organization, the more the problem of information and security become very clear. Thus, they have been obliged to comply with information security issues and adopt the national or international standard. The case is quite different when …

A major portion of government and business organizations’ attempts to counteract information security threats is teams of security personnel. These teams often consist of personnel of diverse backgrounds in specific specialties such as network administration, application development, and business administration, resulting in possible conflicts between security, functionality, and availability. This paper discusses the use of games to teach and research information security teams and outlines research to design and build a simple, team-oriented, configurable, information security game. It will be used to study how information security teams work together to defend against attacks using a multi-player game, and to study …

Making Molehills Out Of Mountains: Bringing Security Research To The Classroom, Richard G. Taylor

Journal of Digital Forensics, Security and Law

Security research published in academic journals rarely finds its way to the business community or into the classroom. Even though the research is of high quality, it is written in a manner that is difficult to read and to understand. This paper argues that one way to get this academic research into the business community is to incorporate it into security classrooms. To do so, however, academic articles need to be adapted into a classroom-friendly format. This paper suggests ways to do this and provides an example of an academic article that was adapted for use in a security management …
