Assessing Terrorist Cyber Threats: Engineering a Functional Construct

Assessing Terrorist Cyber Threats: Engineering a Functional Construct

Access: Use of this item is restricted to the UNT Community.
Date: December 2014
Creator: Morgan, Deanne
Description: Terrorist organizations and individuals make use of the Internet for supportive activities such as communication, recruiting, financing, training, and planning operations. However, little is known about the level of computer-based (“cyber”) threat such terrorist organizations and individuals pose. One step in facilitating the examination and assessment of the level of cyber threat posed by terrorist organizations and individuals is development of an assessment tool or methodology. This tool would guide intelligence collection efforts and would support and facilitate comparative assessment of the cyber threat posed by terrorist organizations and individuals through the provision of a consistent method of assessment across time, amongst organizations and individuals, and between analysts. This study leveraged the professional experience of experts to engineer a new functional construct – a structured analytical technique designed to assess the cyber threat posed by terrorist entities and individuals. The resultant instrument was a novel structured analytical construct that uses defined indicators of a terrorist organization/individual’s intent to carry out cyber attacks, and their capability to actually do so as measures of an organization/individual’s overall level of cyber threat.

Assessment of a Library Learning Theory by Measuring Library Skills of Students Completing an Online Library Instruction Tutorial

Assessment of a Library Learning Theory by Measuring Library Skills of Students Completing an Online Library Instruction Tutorial

Date: May 2007
Creator: Watson, Dana L.
Description: This study is designed to reveal whether students acquire the domains and levels of library skills discussed in a learning library skills theory after participating in an online library instruction tutorial. The acquisition of the library skills is demonstrated through a review of the scores on online tutorial quizzes, responses to a library skills questionnaire, and bibliographies of course research papers. Additional areas to be studied are the characteristics of the participants enrolled in traditional and online courses at a community college and the possible influence of these characteristics on the demonstrated learning of library skills. Multiple measurement methods, identified through assessment of library instruction literature, are used to verify the effectiveness of the library skills theory and to strengthen the validity and reliability of the study results.

Automatic Language Identification for Metadata Records: Measuring the Effectiveness of Various Approaches

Automatic Language Identification for Metadata Records: Measuring the Effectiveness of Various Approaches

Date: May 2015
Creator: Knudson, Ryan Charles
Description: Automatic language identification has been applied to short texts such as queries in information retrieval, but it has not yet been applied to metadata records. Applying this technology to metadata records, particularly their title elements, would enable creators of metadata records to obtain a value for the language element, which is often left blank due to a lack of linguistic expertise. It would also enable the addition of the language value to existing metadata records that currently lack a language value. Titles lend themselves to the problem of language identification mainly due to their shortness, a factor which increases the difficulty of accurately identifying a language. This study implemented four proven approaches to language identification as well as one open-source approach on a collection of multilingual titles of books and movies. Of the five approaches considered, a reduced N-gram frequency profile and distance measure approach outperformed all others, accurately identifying over 83% of all titles in the collection. Future plans are to offer this technology to curators of digital collections for use.

Blogging and Tweens: Communication Portal to Reading Selection and Engagement

Date: May 2012
Creator: Sharber, Shelli K.
Description: The ethnographic study utilized the research techniques of observations, content analysis, and semi-structured interviews with tween participants (i.e., 9 through 13 year-old youth) during an 8-week literary blog project. Twenty-six participants created individual blog pages within a member-only classroom blog site that allowed for online communication between members. the blog project incorporated social networking applications with which youth frequently engage. the research questions ensured data regarding what facets participants found appealing and motivating during the project was collected. the questions allowed for determining if participants utilized peer blogs for reading material selection or repurposed the blogs to discuss other topics. Components of self-determination theory and engagement theory underlay the project design and aided in identifying motivational aspects of the data. Frequency tables outlined the identified patterns and structures of participants’ online activity. Participants found the ability to change the colors of their blog backgrounds and to design their individual blogs and the giving and receiving of feedback to be the two most appealing features of the project. Participants chose books from peer suggestions in the online world but also selected materials from recommendations they received in face-to-face interactions with their peers, their teacher, and the school librarian. Little evidence of ...

Bridging the Theory-to-practice Gap: a Multivariate Correlational Study Exploring the Effects of a Graduate Online Learning Environment As a Community of Practice Framework

Bridging the Theory-to-practice Gap: a Multivariate Correlational Study Exploring the Effects of a Graduate Online Learning Environment As a Community of Practice Framework

Date: December 2013
Creator: Bone, Tonda Jenean
Description: In this multivariate correlational study, the researcher examined the course culture of an online graduate course whose environment exhibited characteristics of a Community of practice (CoP). An online survey captured data used to explore the relationships among variables shown to describe a CoP in field environments and among student perceptions of their experience in the course culture. A canonical correlation analysis (CCA) and commonality analysis (CA) were conducted using five predictor variables and three criterion variables to evaluate the degree and direction of the relationships. The CCA revealed that the full model was significant, explaining approximately 74% of the variance among the two synthetic variates. Impact, faculty leadership, and connection were the largest contributors to the predictor variate. The criterion variate was primarily explained by value and perceived CoP, with exposure to the profession providing a smaller contribution. The CA confirmed these findings. Results from this study indicate that a CoP could be fostered in an online graduate course. The overall significance of the model indicates teachers can nurture an environment wherein graduate students will take the initiative to work with others to create and acquire knowledge that creates a sense of professional connection with each other and with the ...

A Change Agent in the Use of Continuing Online Distance Learning Technology

A Change Agent in the Use of Continuing Online Distance Learning Technology

Date: August 2009
Creator: Lawson, Cheryl L.
Description: Managers of public libraries have been presented with a new set of challenges in the day-to-day operations of public libraries. These include their ability to serve as change agents as they manage the use of continuing online distance learning (CODL) for staff. This online tool may provide staff opportunities for on-the-job learning, yet for managers and managerial staff little is known about how the tool impacts their role in light of the changes. This research investigates the perceptions of 103 Northeast Texas Library System managers and managerial staff about their role as a change agent in the use of CODL using an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to determine the outcome. Administrators from urban, suburban, and rural public libraries were surveyed using a General Training Climate Scale to explore three constructs: extent of the manager role, manager role, and use of CODL. Data analysis was performed using exploratory and confirmatory analysis to support the theoretical model. An altered model was tested and confirmed through model fit indices.

Children's Color Association for Digital Image Retrieval.

Children's Color Association for Digital Image Retrieval.

Date: August 2003
Creator: Chang, Yun-Ke
Description: In the field of information sciences, attention has been focused on developing mature information retrieval systems that abstract information automatically from the contents of information resources, such as books, images and films. As a subset of information retrieval research, content-based image retrieval systems automatically abstract elementary information from images in terms of colors, shapes, and texture. Color is the most commonly used in similarity measurement for content-based image retrieval systems. Human-computer interface design and image retrieval methods benefit from studies based on the understanding of their potential users. Today's children are exposed to digital technology at a very young age, and they will be the major technology users in five to ten years. This study focuses on children's color perception and color association with a controlled set of digital images. The method of survey research was used to gather data for this exploratory study about children's color association from a children's population, third to sixth graders. An online questionnaire with fifteen images was used to collect quantitative data of children's color selections. Face-to-face interviews investigated the rationale and factors affecting the color choices and children's interpretation of the images. The findings in this study indicate that the color children associated ...

The Cluster Hypothesis: A Visual/Statistical Analysis

The Cluster Hypothesis: A Visual/Statistical Analysis

Access: Use of this item is restricted to the UNT Community.
Date: May 2000
Creator: Sullivan, Terry
Description: By allowing judgments based on a small number of exemplar documents to be applied to a larger number of unexamined documents, clustered presentation of search results represents an intuitively attractive possibility for reducing the cognitive resource demands on human users of information retrieval systems. However, clustered presentation of search results is sensible only to the extent that naturally occurring similarity relationships among documents correspond to topically coherent clusters. The Cluster Hypothesis posits just such a systematic relationship between document similarity and topical relevance. To date, experimental validation of the Cluster Hypothesis has proved problematic, with collection-specific results both supporting and failing to support this fundamental theoretical postulate. The present study consists of two computational information visualization experiments, representing a two-tiered test of the Cluster Hypothesis under adverse conditions. Both experiments rely on multidimensionally scaled representations of interdocument similarity matrices. Experiment 1 is a term-reduction condition, in which descriptive titles are extracted from Associated Press news stories drawn from the TREC information retrieval test collection. The clustering behavior of these titles is compared to the behavior of the corresponding full text via statistical analysis of the visual characteristics of a two-dimensional similarity map. Experiment 2 is a dimensionality reduction condition, in ...

Cognitive Playfulness, Innovativeness, and Belief of Essentialness: Characteristics of Educators who have the Ability to Make Enduring Changes in the Integration of Technology into the Classroom Environment.

Date: August 2004
Creator: Dunn, Lemoyne Luette Scott
Description: Research on the adoption of innovation is largely limited to factors affecting immediate change with few studies focusing on enduring or lasting change. The purpose of the study was to examine the personality characteristics of cognitive playfulness, innovativeness, and essentialness beliefs in educators who were able to make an enduring change in pedagogy based on the use of technology in the curriculum within their assigned classroom settings. The study utilized teachers from 33 school districts and one private school in Texas who were first-year participants in the Intel® Teach to the Future program. The research design focused on how cognitive playfulness, innovativeness, and essentialness beliefs relate to a sustained high level of information technology use in the classroom. The research questions were: 1) Are individuals who are highly playful more likely to continue to demonstrate an ability to integrate technology use in the classroom at a high level than those who are less playful? 2) Are individuals who are highly innovative more likely to continue to demonstrate an ability to integrate technology use in the classroom at a high level than those who are less innovative? 3) Are individuals who believe information technology use is critical and indispensable to their ...

A Common Representation Format for Multimedia Documents

A Common Representation Format for Multimedia Documents

Date: December 2002
Creator: Jeong, Ki Tai
Description: Multimedia documents are composed of multiple file format combinations, such as image and text, image and sound, or image, text and sound. The type of multimedia document determines the form of analysis for knowledge architecture design and retrieval methods. Over the last few decades, theories of text analysis have been proposed and applied effectively. In recent years, theories of image and sound analysis have been proposed to work with text retrieval systems and progressed quickly due in part to rapid progress in computer processing speed. Retrieval of multimedia documents formerly was divided into the categories of image and text, and image and sound. While standard retrieval process begins from text only, methods are developing that allow the retrieval process to be accomplished simultaneously using text and image. Although image processing for feature extraction and text processing for term extractions are well understood, there are no prior methods that can combine these two features into a single data structure. This dissertation will introduce a common representation format for multimedia documents (CRFMD) composed of both images and text. For image and text analysis, two techniques are used: the Lorenz Information Measurement and the Word Code. A new process named Jeong's Transform is ...

A Comparative Analysis of Style of User Interface Look and Feel in a Synchronous Computer Supported Cooperative Work Environment

A Comparative Analysis of Style of User Interface Look and Feel in a Synchronous Computer Supported Cooperative Work Environment

Date: May 2005
Creator: Livingston, Alan
Description: The purpose of this study is to determine whether the style of a user interface (i.e., its look and feel) has an effect on the usability of a synchronous computer supported cooperative work (CSCW) environment for delivering Internet-based collaborative content. The problem motivating this study is that people who are located in different places need to be able to communicate with one another. One way to do this is by using complex computer tools that allow users to share information, documents, programs, etc. As an increasing number of business organizations require workers to use these types of complex communication tools, it is important to determine how users regard these types of tools and whether they are perceived to be useful. If a tool, or interface, is not perceived to be useful then it is often not used, or used ineffectively. As organizations strive to improve communication with and among users by providing more Internet-based collaborative environments, the users' experience in this form of delivery may be tied to a style of user interface look and feel that could negatively affect their overall acceptance and satisfaction of the collaborative environment. The significance of this study is that it applies the technology ...

Comparing the Readability of Text Displays on Paper, E-Book Readers, and Small Screen Devices

Comparing the Readability of Text Displays on Paper, E-Book Readers, and Small Screen Devices

Date: May 2010
Creator: Baker, Rebecca Dawn
Description: Science fiction has long promised the digitalization of books. Characters in films and television routinely check their palm-sized (or smaller) electronic displays for fast-scrolling information. However, this very technology, increasingly prevalent in today's world, has not been embraced universally. While the convenience of pocket-sized information pieces has the techno-savvy entranced, the general public still greets the advent of the e-book with a curious reluctance. This lack of enthusiasm seems strange in the face of the many advantages offered by the new medium - vastly superior storage capacity, searchability, portability, lower cost, and instantaneous access. This dissertation addresses the need for research examining the reading comprehension and the role emotional response plays in the perceived performance on e-document formats as compared to traditional paper format. This study compares the relative reading comprehension on three formats (Kindle, iTouch, and paper) and examines the relationship of subject's emotional response and relative technology exposure as factors that affect how the subject perceives they have performed on those formats. This study demonstrates that, for basic reading comprehension, the medium does not matter. Furthermore, it shows that, the more uncomfortable a person is with technology and expertise in the requested task (in this case, reading), the ...

A Comparison of Communication Motives of On-Site and Off-Site Students in Videoconference-Based Courses

A Comparison of Communication Motives of On-Site and Off-Site Students in Videoconference-Based Courses

Date: August 2002
Creator: Massingill, K.B.
Description: The objective of this investigation is to determine whether student site location in an instructional videoconference is related to students' motives for communicating with their instructor. The study is based, in part, on the work of Martin et al. who identify five separate student-teacher communication motives. These motives, or dimensions, are termed relational, functional, excuse, participation, and sycophancy, and are measured by a 30-item questionnaire. Several communication-related theories were used to predict differences between on-site and off-site students, Media richness theory was used, foundationally, to explain differences between mediated and face-to-face communication and other theories such as uncertainty reduction theory were used in conjunction with media richness theory to predict specific differences.Two hundred eighty-one completed questionnaires were obtained from Education and Library and Information Science students in 17 separate course-sections employing interactive video at the University of North Texas during the Spring and Summer semesters of the 2001/2002 school year. This study concludes that off-site students in an instructional videoconference are more likely than their on-site peers to report being motivated to communicate with their instructor for participation reasons. If off-site students are more motivated than on-site students to communicate as a means to participate, then it may be important ...

A Complex Systems Model for Understanding the Causes of Corruption: Case Study - Turkey

A Complex Systems Model for Understanding the Causes of Corruption: Case Study - Turkey

Date: August 2005
Creator: Yasar, Muhammet Murat
Description: It is attempted with this dissertation to draw an explanatory interdisciplinary framework to clarify the causes of systemic corruption. Following an intense review of political sciences, economics, and sociology literatures on the issue, a complex systems theoretical model is constructed. A political system consists of five main components: Society, interest aggregators, legislative, executive and private sector, and the human actors in these domains. It is hypothesized that when the legitimacy level of the system is low and morality of the systemic actors is flawed, selected political, social and economic incentives and opportunities that may exist within the structure of the systemic components might -individually or as a group- trigger corrupt transactions between the actors of the system. If left untouched, corruption might spread through the system by repetition and social learning eventually becoming the source of corruption itself. By eroding the already weak legitimacy and morality, it may increase the risk of corruption even further. This theoretical explanation is used to study causes of systemic corruption in the Turkish political system. Under the guidance of the complex systems theory, initial systemic conditions, -legacy of the predecessor of Turkey Ottoman Empire-, is evaluated first, and then political, social and economic factors ...

Computer Support Interactions: Verifying a Process Model of Problem Trajectory in an Information Technology Support Environment.

Date: December 2006
Creator: Strauss, Christopher Eric
Description: Observations in the information technology (IT) support environment and generalizations from the literature regarding problem resolution behavior indicate that computer support staff seldom store reusable solution information effectively for IT problems. A comprehensive model of the processes encompassing problem arrival and assessment, expertise selection, problem resolution, and solution recording has not been available to facilitate research in this domain. This investigation employed the findings from a qualitative pilot study of IT support staff information behaviors to develop and explicate a detailed model of problem trajectory. Based on a model from clinical studies, this model encompassed a trajectory scheme that included the communication media, characteristics of the problem, decision points in the problem resolution process, and knowledge creation in the form of solution storage. The research design included the administration of an extensive scenario-based online survey to a purposive sample of IT support staff at a medium-sized state-supported university, with additional respondents from online communities of IT support managers and call-tracking software developers. The investigator analyzed 109 completed surveys and conducted email interviews of a stratified nonrandom sample of survey respondents to evaluate the suitability of the model. The investigation employed mixed methods including descriptive statistics, effects size analysis, and content ...

A Conceptual Map for Understanding the Terrorist Recruitment Process: Observation and Analysis of Turkish Hezbollah Terrorist Organizations.

Date: August 2007
Creator: Teymur, Samih
Description: Terrorism is a historical problem; however, it becomes one of the biggest problems in 21st century. September 11 and the following Madrid, Istanbul and London attacks showed that it is the most significant problem threatening world peace and security. Governments have started to deal with terrorism by improving security measurements and making new investments to stop terrorism. Most of the governments' and scholars' focus is on immediate threats and causes of terrorism, instead of looking at long-term solutions such as root causes and underlying reasons of terrorism, and the recruitment style of terrorist organizations If terrorist recruitment does not stop, then it is safe to say terrorist activities cannot be stopped. This study focused on the recruitment process by observing two different terrorist organizations, DHKP/C and Turkish Hezbollah. The researcher brings 13 years of field experience and first-person data gathered from inside the terrorist organizations. The research questions of this study were: (i) How can an individual be prevented from joining or carrying out terrorist activities?; (ii) What factors are correlated with joining a terrorist organization?; (iii) What are the recruitment processes of the DHKP/C, PKK, and Turkish Hezbollah?; (iv) Is there any common process of being a member of ...

Constraints on Adoption of Innovations: Internet Availability in the Developing World.

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Stedman, Joseph B.
Description: In a world that is increasingly united in time and distance, I examine why the world is increasingly divided socially, economically, and digitally. Using data for 35 variables from 93 countries, I separate the countries into groups of 31 each by gross domestic product per capita. These groups of developed, lesser developed and least developed countries are used in comparative analysis. Through a review of relevant literature and tests of bivariate correlation, I select eight key variables that are significantly related to information communication technology development and to human development. For this research, adoption of the Internet in the developing world is the innovation of particular interest. Thus, for comparative purposes, I chose Internet Users per 1000 persons per country and the Human Development Index as the dependent variables upon which the independent variables are regressed. Although small in numbers among the least developed countries, I find Internet Users as the most powerful influence on human development for the poorest countries. The research focuses on key obstacles as well as variables of opportunity for Internet usage in developing countries. The greatest obstacles are in fact related to Internet availability and the cost/need ratio for infrastructure expansion. However, innovations for expanded ...

Convenience to the Cataloger or Convenience to the User? An Exploratory Study of Catalogers’ Judgment

Date: May 2015
Creator: Hasenyager, Richard Lee Jr.
Description: This mixed-method study explored cataloger’s judgment through the presence of text as entered by catalogers for the 11 electronic resource items during the National Libraries test for Resource Description and Access (RDA). Although the literature discusses cataloger’s judgment and suggests that cataloging practice based on new cataloging code RDA will more heavily rely on cataloger’s judgment, the topic of cataloger’s judgment in RDA cataloging was not formally studied. The purpose of this study was to study the differences and similarities in the MARC records created as a part of the RDA National Test and to determine if the theory of bounded rationality could explain cataloger’s judgment based on the constructs of cognitive and temporal limits. This goal was addressed through a content analysis of the MARC records and various statistical tests (Pearson’s Chi-square, Fisher’s Exact, and Cramer’s V). Analysis of 217 MARC records was performed on seven elements of the bibliographic record. This study found that there were both similarities and differences among the various groups of participants, and there are indications that both support and refute the assertion that catalogers make decisions based on the constructs of time and cognitive ability. Future research is needed to be able to ...

Conversational Use of Photographic Images on Facebook:  Modeling Visual Thinking on Social Media

Conversational Use of Photographic Images on Facebook: Modeling Visual Thinking on Social Media

Date: May 2016
Creator: Albannai, Talal N.
Description: Modeling the "thick description" of photographs began at the intersection of personal and institutional descriptions. Comparing institutional descriptions of particular photos that were also used in personal online conversations was the initial phase. Analyzing conversations that started with a photographic image from the collection of the Library of Congress (LC) or the collection of the Manchester Historic Association (MHA) provided insights into how cultural heritage institutions could enrich the description of photographs by using informal descriptions such as those applied by Facebook users. Taking photos of family members, friends, places, and interesting objects is something people do often in their daily lives. Some photographic images are stored, and some are shared with others in gatherings, occasions, and holidays. Face-to-face conversations about remembering some of the details of photographs and the event they record are themselves rarely recorded. Digital cameras make it easy to share personal photos in Web conversations and to duplicate old photos and share them on the Internet. The World Wide Web even makes it simple to insert images from cultural heritage institutions in order to enhance conversations. Images have been used as tokens within conversations along with the sharing of information and background knowledge about them. The ...

Coyote Ugly Librarian: A Participant Observer Examination of Lnowledge Construction in Reality TV.

Date: May 2007
Creator: Holmes, Haley K.
Description: Reality TV is the most popular genre of television programming today. The number of reality television shows has grown exponentially over the last fifteen years since the premier of The Real World in 1992. Although reality TV uses styles similar to those used in documentary film, the “reality” of the shows is questioned by critics and viewers alike. The current study focuses on the “reality” that is presented to viewers and how that “reality” is created and may differ from what the participants of the shows experience. I appeared on two reality shows, Faking It and That's Clever, and learned a great deal as a participant observer. Within the study, I outline my experience and demonstrate how editing changed the reality I experienced into what was presented to the viewers. O'Connor's (1996) representation context web serves as a model for the realities created through reality television. People derive various benefits from watching reality TV. Besides the obvious entertainment value of reality TV, viewers also gather information via this type of programming. Viewers want to see real people on television reacting to unusual circumstances without the use of scripts. By surveying reality TV show viewers and participants, this study gives insight ...

Creating a Criterion-Based Information Agent Through Data Mining for Automated Identification of Scholarly Research on the World Wide Web

Creating a Criterion-Based Information Agent Through Data Mining for Automated Identification of Scholarly Research on the World Wide Web

Date: May 2000
Creator: Nicholson, Scott
Description: This dissertation creates an information agent that correctly identifies Web pages containing scholarly research approximately 96% of the time. It does this by analyzing the Web page with a set of criteria, and then uses a classification tree to arrive at a decision. The criteria were gathered from the literature on selecting print and electronic materials for academic libraries. A Delphi study was done with an international panel of librarians to expand and refine the criteria until a list of 41 operationalizable criteria was agreed upon. A Perl program was then designed to analyze a Web page and determine a numerical value for each criterion. A large collection of Web pages was gathered comprising 5,000 pages that contain the full work of scholarly research and 5,000 random pages, representative of user searches, which do not contain scholarly research. Datasets were built by running the Perl program on these Web pages. The datasets were split into model building and testing sets. Data mining was then used to create different classification models. Four techniques were used: logistic regression, nonparametric discriminant analysis, classification trees, and neural networks. The models were created with the model datasets and then tested against the test dataset. Precision ...

CT3 as an Index of Knowledge Domain Structure: Distributions for Order Analysis and Information Hierarchies

Date: December 2002
Creator: Swartz Horn, Rebecca
Description: The problem with which this study is concerned is articulating all possible CT3 and KR21 reliability measures for every case of a 5x5 binary matrix (32,996,500 possible matrices). The study has three purposes. The first purpose is to calculate CT3 for every matrix and compare the results to the proposed optimum range of .3 to .5. The second purpose is to compare the results from the calculation of KR21 and CT3 reliability measures. The third purpose is to calculate CT3 and KR21 on every strand of a class test whose item set has been reduced using the difficulty strata identified by Order Analysis. The study was conducted by writing a computer program to articulate all possible 5 x 5 matrices. The program also calculated CT3 and KR21 reliability measures for each matrix. The nonparametric technique of Order Analysis was applied to two sections of test items to stratify the items into difficulty levels. The difficulty levels were used to reduce the item set from 22 to 9 items. All possible strands or chains of these items were identified so that both reliability measures (CT3 and KR21) could be calculated. One major finding of this study indicates that .3 to .5 ...

The Denial of Relevance: Biography of a Quest(ion) Amidst the Min(d)fields—groping and Stumbling

Date: August 2014
Creator: VanBebber, Marion Turner
Description: Early research on just why it might be the case that “the mass of men lead lives of quiet desperation” suggested that denial of relevance was a significant factor. Asking why denial of relevance would be significant and how it might be resolved began to raise issues of the very nature of questions. Pursuing the nature of questions, in light of denial of relevance and Thoreau’s “quiet desperation” provoked a journey of modeling questions and constructing a biography of the initial question of this research and its evolution. Engaging literature from philosophy, neuroscience, and retrieval then combined with deep interviews of successful lawyers to render a thick, biographical model of questioning.

Date: May 2002
Creator: Reames, Steve
Description: There is currently no effective tool available to quickly and economically measure a change in landmass in the setting of biomedical professionals and environmental specialists. The purpose of this study is to structure and demonstrate a statistical change-detection method using remotely sensed data that can detect the presence of an infectious land borne disease. Data sources included the Texas Department of Health database, which provided the types of infectious land borne diseases and indicated the geographical area to study. Methods of data collection included the gathering of images produced by digital orthophoto quadrangle and aerial videography and Landsat. Also, a method was developed to identify statistically the severity of changes of the landmass over a three-year period. Data analysis included using a unique statistical detection procedure to measure the severity of change in landmass when a disease was not present and when the disease was present. The statistical detection method was applied to two different remotely sensed platform types and again to two like remotely sensed platform types. The results indicated that when the statistical change detection method was used for two different types of remote sensing mediums (i.e.-digital orthophoto quadrangle and aerial videography), the results were negative due to ...
