Performance Measurement Framework For Hierarchical Text Classification, Ee Peng Lim, Aixin Sun, Wee-Keong Ng

Research Collection School Of Computing and Information Systems

Hierarchical text classification or simply hierarchical classification refers to assigning a document to one or more suitable categories from a hierarchical category space. In our literature survey, we have found that the existing hierarchical classification experiments used a variety of measures to evaluate performance. These performance measures often assume independence between categories and do not consider documents misclassified into categories that are similar or not far from the correct categories in the category tree. In this paper, we therefore propose new performance measures for hierarchical classification. The proposed performance measures consist of category similarity measures and distance-based measures that consider …

An Examination Of Socially Constructed Whole Group Storybook Reading In Three Pre Primary Classrooms, Anne Drabble

Theses: Doctorates and Masters

This study examines the socially constructed context of whole group storybook reading in pre primary classrooms. The study is centred in the shared communications that occur between pre primary teachers and students before, during and after the storybook reading. In particular, insights are sought on the nature and extent of the pre primary teachers' and the pre primary students' communicative contributions and the opportunity provided for the inclusion of personal knowledge and personal experience in the communication. Whether there is a change in the nature of the contributions over time is also examined. The study seeks to extend current understanding …

A Study Of The Security Implications Involved With The Use Of Executable World Wide Web Content, Christopher Hu

Theses: Doctorates and Masters

Malicious executable code is nothing new. While many consider that the concept of malicious code began in the 1980s when the first PC viruses began to emerge, the concept does in fact date back even earlier. Throughout the history of malicious code, methods of hostile code delivery have mirrored prevailing patterns of code distribution. In the 1980s, file infecting and boot sector viruses were common, mirroring the fact that during this time, executable code was commonly transferred via floppy disks. Since the 1990s email has been a major vector for malicious code attacks. Again, this mirrors the fact that during …

The Mediated Data Integration (Medint) : An Approach To The Integration Of Database And Legacy Systems, Suvimol Mukviboonchai

Theses: Doctorates and Masters

The information required for decision making by executives in organizations is normally scattered across disparate data sources including databases and legacy systems. To gain a competitive advantage, it is extremely important for executives to be able to obtain one unique view of information in an accurate and timely manner. To do this, it is necessary to interoperate multiple data sources, which differ structurally and semantically. Particular problems occur when applying traditional integration approaches, for example, the global schema needs to be recreated when the component schema has been modified. This research investigates the following heterogeneities between heterogeneous data sources: Data …

Automatic Human Face Detection In Color Images, Son Lam Phung

Theses: Doctorates and Masters

Automatic human face detection in digital image has been an active area of research over the past decade. Among its numerous applications, face detection plays a key role in face recognition system for biometric personal identification, face tracking for intelligent human computer interface (HCI), and face segmentation for object-based video coding. Despite significant progress in the field in recent years, detecting human faces in unconstrained and complex images remains a challenging problem in computer vision. An automatic system that possesses a similar capability as the human vision system in detecting faces is still a far-reaching goal. This thesis focuses on …

Ellipsis In Science And Technology Textbooks In English: Implications For Thai Students, Sripen Srestasathiern

Theses: Doctorates and Masters

This is an analytical study which attempted to investigate Thai students' ability to interpret elliptical sentences and to recover and recognise ellipted elements in a science and technology context in English. Students' awareness, understanding, perceptions, problems and strategies in relation to ellipsis were also examined. The subjects for the study were 60 first year students from King Mongkut's Institute of Technology North Bangkok (KMITNB) who had enrolled in two compulsory English courses in KMITNB, Bangkok, Thailand. The instruments for this study were three 20 item ellipsis tests based on 5 ellipsis types classified by Quirk, et al. (1985). Items of …

Nature Of Talk And Interaction In The Singapore History Classroom, Pamela Chellappah Thuraisingam

Theses: Doctorates and Masters

History is a complex subject. It is more propositional than procedural in nature (Nichol, 1984), and involves adductive thinking (Booth, 1983), where historical evidence and facts are 'teased out' and a convincing account of the past is then reconstructed through speculation, imagination and empathy (Nichol, 1984; Booth, 1983). The teaching and learning of history should not just be the transmission of knowledge, but rather it should involve a process whereby students and teachers interact in order to analyze evidence, raise questions and hypotheses, synthesize facts, and communicate their ideas, understand others' viewpoints, consider values, reflect and engage in moral reasoning …

Good Life In The Balance: A Cross-National Study Of Dutch And Australian Disability Perspectives On Euthanasia And Physician-Assisted Suicide, Erik A. Leipoldt

Theses: Doctorates and Masters

This is a cross-national qualitative study with the purpose of obtaining perspectives held by people with quadriplegia and leading figures in disability movements in the Netherlands and Australia on the issues of euthanasia and physician-assisted suicide (EPAS). A disability voice is not prominent in public debate on EPAS in Australia or the Netherlands, even though people with disabilities are often thought to be vulnerable in relation to EPAS policies. Disability perspectives are potentially valuable in illuminating issues in relation to euthanasia and physician-assisted suicide, because issues of dependence, independence, and individual autonomy play important roles in relation to both EPAS …

Validity And Obligation In Natural Law Theory, Seow Hon Tan

Research Collection Yong Pung How School Of Law

The relation between law and morality is a point of contention amongst legal philosophers. There are several issues: first, the extent to which law should incorporate moral standards; second, the effect of moral status on legal validity (the "validity question"); third, the effect of legal validity on the obligation created by the law (the "obedience question"). Because most positivists concede that it is desirable for law to accord with notions of justice and morals and that law often incorporates morals, the first issue features less prominently in the positivism-natural law debate. This article examines John Finnis's views on the latter …

Body Image, Eating Disturbance And Estrogen Levels Across The Menstrual Cycle, Mei-Chuan Wang

Dissertations and Theses @ UNI

The principal interest of the current study was to examine estrogen levels across the menstrual cycle related to body image and eating disturbance. Participants were undergraduate female students at a medium size Midwestern university. There were two phases of this study-a between-subjects aspect (N = 119) followed by a within-subjects aspect (N = 41 ). Multivariate analyses of covariance (MANCO VA) were used to analyze the first phase data. Results showed that when eating disorders were viewed as a whole. eating patterns were stable across the menstrual cycle; but if looked at separately. symptoms of anorexia were worse when estrogen …

Improving The Word Recognition And Decoding Skills Of High School Students, Dorothy Reed

Abraham S. Fischler College of Education ETD Archive

This applied dissertation was designed to provide African American high school students with a number of reading strategies that they could use when confronted with unfamiliar words. These strategies would allow the students to recognize unfamiliar words rapidly and independently. Although the participants of the host community continued to make progress academically and are currently in their expected grades they have struggled in the area of reading. None of them have been identified by school officials as students who struggle with reading consequently, these students are not receiving special services in the schools they attend. As a result, African American …

Parents, Educators, Law Enforcement, And Participation In Delinquent Behavior: Gender Socialization And Views Of Life Changes, Jolie Marie Imler

Dissertations and Theses @ UNI

The task of the proposed research is to determine the extent parents, educators, law enforcement, and participation in delinquent behavior influence responses of youth toward their hopefulness for the future and likelihood of attending college and whether the relationships differ by gender. Using gender socialization, social capital, and labeling theories as theoretical backgrounds, it is anticipated that contradictory socialization patterns, gendered access to social capital, and labels influence the resources and responses of female juveniles when considering hopefulness for the future and the likelihood of attending college. The proposed study will use secondary data comprised of youth either adjudicated delinquent …

A Comparison Of The Epithelium To Mesenchyme Transformation Process In Cultured Embryonic Chick Neural Crest Cells And Human Metastatic Cervical Cancer Cells, Molly Decker

Presidential Scholars Theses (1990 – 2006)

Embryonic neural crest cells (NCCs) and metastasizing cancer cells both undergo an epithelium to mesenchyme transformation (EMT) during which they disengage from neighboring cells and basement membrane and actively migrate to new locations. NCCs, small groups of cells that emerge from the neural tube, move directionally through adjacent tissues to reach specific destinations where they differentiate into a diverse array of specific cells and tissues. Caski cells are an established line of metastatic cervical cancer cells that contain HPV. We compared NCCs to Caski cells during EMT with respect to the expression of key proteins related to cell migration-integrin, paxillin, …

Teacher Perceptions Of Iowa Workshop Model Aspects Fostering Use Of Project Wet, Marcene Seavey

Dissertations and Theses @ UNI

State partners of national environmental education (EE) programs contribute to professional development in EE through their program delivery. This study describes teacher perceptions of individual elements of EE workshops provided by one such program, Iowa Project WET. The study found that educators associate three types of workshop activities with successful classroom integration of Project WET activities: ( a) Experiencing activities first-hand, (b) interacting with other educators, and (c) learning about the Project WET Activity and Curriculum Guide. Almost 90% of survey respondents integrate some of the activities they experience during the workshop into their classrooms. Some of these teachers also …

Habitat Associations And Ecology Of Sonoma Tree Vole (Arborimus Pomo) In Northwest California, Jennifer M. Jones

Cal Poly Humboldt theses and projects

The Sonoma tree vole (Arborimus porno) is a California Species of Special Concern and an important prey species of the Northern Spotted Owl (Strix occidentalis caurina). Management of A. porno has been limited by the scarcity of biological data and a lack of understanding of its habitat requirements. I compared relative tree vole abundance among three size classes of Douglas-fir (Pseudotsuga rnenziesii) stands in 2000: pole (15-28 cm DBH), unthinned young-growth (29-61 cm DBH), and mature (>61 cm DBH). Four stands of each size class were searched for A. pomo nests using line transects on The Pacific Lumber Company …

Questions About The Efficiency Of Employment Arbitration Agreements, Matthew T. Bodie

All Faculty Scholarship

The growing popularity of arbitration agreements is well-documented. The academic literature on these agreements has been largely critical, arguing that they jeopardize important rights and enable employers to take unfair advantage of employees and consumers. However, standard economic analysis suggests that since these agreements are freely negotiated, they presumably increase the utility of both parties and are therefore efficient. This Article raises questions about the efficiency of such agreements in the employment context. It begins by modeling the decision-making process by which a rational employee would judge the desirability of an agreement, both after and before a dispute has arisen. …

Reforming Civil Rights With Systems Reform: Health Care Disparities, Translation Services, & Safe Harbors, Sidney D. Watson

All Faculty Scholarship

Looking gaunt but determined, 59 year-old Robert Tools was introduced on August 21, 2001, as a medical miracle-the first surviving recipient of a fully implantable artificial heart. At a news conference, Tools spoke with emotion about his second chance at life and the quality of his care. His physician looked on with obvious affection, grateful and honored to have extended Tools's life. Mr. Tools has since lost his battle for life, but will be remembered as a hero for undergoing an experimental technology and paving the way for other patients to undergo the procedure. Moreover, the fact that Tools was …

State Revocation Of Law Enforcement Officers' Licenses And Federal Criminal Prosecution: An Opportunity For Cooperative Federalism, Roger L. Goldman

All Faculty Scholarship

This article suggests ways that Department of Justice Attorneys who prosecute state and local law enforcement officers for violation of civil rights under 18 USC §§ 241 and 242 could use state laws that permit revocation of law enforcement officers’ licenses. Whereas federal criminal convictions of non-law enforcement defendants are close to 100%, statistics indicate that when law enforcement officers are go to trial in federal court, the conviction rate is closer to 50%. Thus, if a jury is unlikely to convict because of its natural sympathies towards the officer, prosecutor should seriously consider permitting the officer to agree to …

Substantially Limited Justice?: The Possibilities And Limits Of A New Rawlsian Analysis Of Disability-Based Discrimination, Elizabeth Pendo

All Faculty Scholarship

In its recent terms, the Supreme Court has increasingly turned its attention toward the Americans with Disabilities Act, and specifically the questions of who should be protected under the ADA, and what such protection requires. In the wake of the Court's decisions, workers have found it increasingly difficult to assert and protect their right to be free of disability-based discrimination in the workplace. Given the widespread influence of John Rawls in contemporary discussions of social, political and economic justice, his recent and final formulation of his theory of distributive justice presents a significant and promising philosophical foundation for evaluation of …

Development Of A Weapons-Of-Mass-Destruction First-Responders Training Program For Peterson Clinic With Plans For Implementation And Evaluation, Angela M. Thompson

Abraham S. Fischler College of Education ETD Archive

The problem was that there was no valid training program in place to provide the Peterson Clinic first responders with the training they needed to respond effectively to a weapons of mass destruction (WMD) incident involving up to 300 patients. The purpose of this applied dissertation was to develop a WMD First-Responders Training Program for the Peterson Clinic with plans for implementation and evaluation.

A development methodology with a plan to implement and a plan to evaluate was used to complete this project. As a preliminary procedure, the needs assessment methodology was used to determine the training needs of the …
