Network Intrusion Detection: Monitoring, Simulation And Visualization, Mian Zhou

Electronic Theses and Dissertations

This dissertation presents our work on network intrusion detection and intrusion sim- ulation. The work in intrusion detection consists of two different network anomaly-based approaches. The work in intrusion simulation introduces a model using explicit traffic gen- eration for the packet level traffic simulation. The process of anomaly detection is to first build profiles for the normal network activity and then mark any events or activities that deviate from the normal profiles as suspicious. Based on the different schemes of creating the normal activity profiles, we introduce two approaches for intrusion detection. The first one is a frequency-based approach which …

Perceived Stress, Coping, And Adequacy Of Social Support: Implications For Subjective Well-Being In College Students, Kia Asberg

Electronic Theses and Dissertations

Stress is a widespread concept commonly associated with psychological and medical problems that may impair an individual's functioning and incur costs on society. Alarming rates of depression, anxiety, suicidal ideation, and other stress-related problems have been found among college students. This study (N = 241)argues that reducing emotional and financial stress-related costs may be possible through increasing public and professional awareness of moderating variables, such as social support and coping resources. Results indicated that stress, inadequate social support, and escape-avoidance coping were related to higher levels of depression and lower life satisfaction in both males and females. Social support functioned …

Development And Validation Of The Beile Test Of Information Literacy For Education (B-Tiled), Penny Beile O'Neil

Electronic Theses and Dissertations

Few constituencies exist where it is more important to produce information literate individuals than teacher candidates, yet rarely is it suggested that practitioners entering the field are adequately prepared to teach and model information literacy to their students. As a result, information literacy has been established as a key outcome by a number of teacher education accrediting bodies and professional associations. Corollary to this initiative is the effort to develop valid instruments that assess information literacy skills. Yet, at the time of this dissertation, no rigorously reviewed instruments were uncovered that measure the information literacy skills levels of teacher candidates. …

Modeling Satellite Formations In The Presence Of Perturbations, Robert Cannaday

The purpose of this paper is to develop and describe a numerical simulation of the orbital environment including central force field perturbations and atmospheric drag effects which will be a useful analytical tool for investigating issues relating to maintaining satellite formations in low-earth-orbit. Many of the studies …

Optical Wave Propagation In Discrete Waveguide Arrays, Jared Hudock

Electronic Theses and Dissertations

The propagation dynamics of light in optical waveguide arrays is characteristic of that encountered in discrete systems. As a result, it is possible to engineer the diffraction properties of such structures, which leads to the ability to control the flow of light in ways that are impossible in continuous media. In this work, a detailed theoretical investigation of both linear and nonlinear optical wave propagation in one- and two-dimensional waveguide lattices is presented. The ability to completely overcome the effects of discrete diffraction through the mutual trapping of two orthogonally polarized coherent beams interacting in Kerr nonlinear arrays of birefringent …

Employee Motivation: A Comparison Of Tipped And Non-Tipped Hourly Restaurant Employees, Catherine Johnson

Electronic Theses and Dissertations

Employee motivation shall be defined by Robbins (as cited in Ramlall, 2004) as: "the willingness to exert high levels of effort toward organizational goals, conditioned by the effort's ability to satisfy some individual need." To engage in the practice of motivating employees, employers must understand the unsatisfied needs of each of the employee groups. This study desires to provide practitioners in the restaurant industry the ability to recognize motivators for these different employment groups and their relationship to organizational commitment. The restaurant industry consists of two types of employees: salaried and hourly. This study focuses on hourly employees, and their …

Resource Allocation Using Touch And Audition, David Mortimer

Electronic Theses and Dissertations

When people multi-task with inputs that demand attention, processing, andencoding, sensory interference is possible at almost any level. Multiple Resource Theory (MRT) suggests that such interference may be avoided by drawing from separate pools of resources available when using different sensory channels, memory processes, and even different response modes. Thus, there should be advantages in dividing tasks among different sensory channels to tap independent pools of attentional resources. For example, people are better with two tasks using the eye and ear, than when using two auditory or two visual inputs. The majority of the research on MRT involves visual to …

High Gain / Broadband Oxide Glasses For Next Generation Raman Amplifiers, Clara Rivero

Electronic Theses and Dissertations

Interest in Raman amplification has undergone a revival due to the rapidly increasing bandwidth requirements for communications transmission, both for long haul and local area networks, and recent developments in the telecom fiber industry and diode laser technology. In contrast to rare earth doped fiber amplifiers, for which the range of wavelengths is fixed and limited, Raman gain bandwidths are larger and the operating wavelength is fixed only by the pump wavelength and the bandwidth of the Raman active medium. In this context, glasses are the material of choice for this application due to their relatively broad spectral response, and …

An Action Research Study Involving Fifth-Grade Students Learning Fractions Through A Situative Perspective With Story Problems, Colleen Allen

Electronic Theses and Dissertations

The purpose of this action research study was to investigate the affects of teaching through a situative perspective with story problems on students' understanding of fraction concepts and operations in my fifth-grade mathematics classroom. Students participated in twelve weeks of instruction. Data was collected in the form of pre and post tests, audiotaped and videotaped recordings of instructional sessions, and student work samples. Data analysis revealed that my students constructed their own knowledge about various fraction concepts and operations because students engaged in discussions, after solving story problems, that developed, extended and restructured their knowledge. One example of this occurred …

Latinate Word Parts And Vocabulary:Contrasts Among Three Groups Comprisingthe Community College Preparatory Reading Class, Tom Bellomo

Electronic Theses and Dissertations

Students enrolled in a college preparatory reading class at one particular community college were categorized based on language origin. Native English speaking students comprised one group and foreign students formed two additional groups--students whose language origin was Latin-based (i.e. Romance languages) and students whose language origin was not Latin-based (i.e. Japanese). A pretest assessment measure was used to quantify the extent that pre-existing knowledge of Latinate word parts and morphologically complex vocabulary differed among groups based on language origin. The identical instrument served as a posttest to measure the extent that direct instruction in morphological analysis resulted in change among …

Vibrotactile Guidance Cues For Target Identification, Joshua Downs

Electronic Theses and Dissertations

The purpose of this dissertation was to establish how vibrotactile guidance cues can be used to improve marksmanship. This work originated in an effort to provide covert communication, navigation, and weapon aiming cues for infantrymen. It is predominantly an application-driven investigation rather than driven a priori by specific theoretical predictions from models of human performance. Three experiments are presented. Experiment 1 established the affect on initial response to vibrotactile guidance cues of tactor placements on the palmer versus dorsal surface of the hand, and targets appearing left versus right of center. Results suggest that tactile cues provided on the left …

A Study Of The Cost-Utility Of Outcomes Of Various Methods Of Increasing The Four-Year Graduation Rate In Osceola County Public Schools, Isaac Harold Berger

Electronic Theses and Dissertations

The purpose of this study was to determine which interventions were deemed to be effective at increasing the four-year graduation rate in Osceola District Schools. This had become a concern due to the fact that this rate had decreased in recent years, and may be utilized as a predictor of the dropout rate. The interventions were then prioritized according to Levin's cost-utility theory, so that the order of implementation could be prioritized. The study was conducted in January and February of 2005, and responses were elicited from 600 people. Students currently in Osceola District Schools high schools comprised 200 of …

Second Language Learners' Recognition Of Unknown Words, Chai-Wei Lin

Electronic Theses and Dissertations

Recent research has underscored the important role of second language (L2) vocabulary acquisition in the reading process. The present study examined how accurately eighteen learners of English as a Second Language (ESL) were able to identify unknown words within a reading passage. It is assumed that "noticing" unfamiliar words in a text plays an important role in being able to extract meaning from context, which may ultimately result in word learning; thus, whether or not learners are able to recognize unknown words as unknown is a key step in vocabulary learning. The design of this study was based on previous …

What Do Physicians Want? Information Technology Acceptance And Usage By Healthcare Professionals, Virginia Ilie

Electronic Theses and Dissertations

This study builds on the theory of planned behavior, institutional and innovation diffusion theories to investigate physicians' responses to introduction of electronic medical records (EMR) in large healthcare organizations. Using a case study methodology, we show that physicians' attitudes towards using EMR are influenced by their perceptions of EMR complexity, relative advantage, compatibility with professional beliefs and individual predisposition to change. Specifically, we found that EMR usability characteristics such as system interface, "navigation," "search" and "speed" are major dimensions underlying physicians' perceptions of EMR complexity. To the extent that navigating and searching for clinical results are seen as difficult, physicians' …

On The Nature Of Corporations, Lynn A. Stout

Cornell Law Faculty Publications

Legal experts traditionally distinguish corporations from unincorporated business forms by focusing on corporate characteristics like limited shareholder liability, centralized management, perpetual life, and free transferability of shares. While such approaches have value, this essay argues that the nature of the corporation can be better understood by focusing on a fifth, often-overlooked, characteristic of corporations: their capacity to "lock in" equity investors' initial capital contributions by making it far more difficult for those investors to subsequently withdraw assets from the firm. Like a tar pit, a corporation is much easier for equity investors to get into, than to get out of. …

These efforts by educators and lawmakers have been made to improve the quality and limit the cost of the educational system. While research exists on many effects of consolidation, findings have been mixed in determining the overall effectiveness of consolidating schools. Research has generally indicated a strong relationship between student participation in extracurricular activities and higher levels of student achievement. Little, if any, research has been conducted on the relationship between school consolidation and extracurricular activity participation. This study was conducted to determine the effects of consolidation …

Self-Narratives For Christian Multicultural Educators: A Pathway To Understanding Self And Others, Heewon Chang

International Christian Community of Teacher Educators Journal

As cultural diversity increases in classrooms, it becomes imperative for teachers to gain multicultural competency so that they can provide effective instruction to diverse students. This paper argues that the development of multicultural competency should be solidly grounded on reflective, empathic, and critical understanding of one’s own culture as well as others. This cultural understanding, particularly from a Christian perspective, recognizes the connectivity of self and others in God. To enhance the cultural understanding, the author recommends studying self-narratives written by others and writing one’s own cultural autobiography. Keywords: cultural autobiography, self-narratives, self-reflection, multicultural teacher education, discourse of others.

Enhancing The Status Of Non-State Actors Through A Global War On Terror?, Mary Ellen O'Connell

Journal Articles

Soon after September 11, President Bush declared a global war on terrorism and members of terrorist groups "combatants." These declarations are not only generally inconsistent with international law; they also reverse the trend regarding the legal status of international non-state actors. For decades, law-abiding non-state actors, such as international humanitarian aid organizations, enjoyed ever-expanding rights on the international plane. Professor Schachter observed how this trend came at the expense of the nation-state. He also predicted, however, that the nation-state would not fade away any time soon. And, by the late Twentieth Century, the trend toward enhanced status was noticeably slowing. …

Management Localization And Performance Of Mncs In China : A Contingent Resource-Based View, Shengsheng Huang

Lingnan Theses

Although many foreign invested enterprises (FIEs) and consultants in China put the localization to a strategic level, management localization is still an emerging issue of human resource management in academic research. A few previous studies on management localization focused on the internal efficiency of the subsidiaries or parent-subsidiary relationship. The impact of management localization on the interaction between the subsidiary and local environment has received little attention. Moreover, localization lacks a consistent and valid definition. This thesis attempts to bridge the gap by systematically exploring the strategic impact of management localization. Management localization is defined as substituting expatriate managers with …

Effects Of Goal Interdependence And Social Identity On Departments And Their Relationships In China, Liyan Wang

Lingnan Theses

Synergy among departments is increasingly considered vital for organizations to use their full resources to deal with threats and explore opportunities in the rapidly changing marketplace. Although valuable, developing synergy among departments is a difficult management challenge.

Departments within organizations often have their own business goals, yet the coordination of these goals is a precondition for overall organizational effectiveness. The need for goal coordination makes departments interdependent (Thompson, 1967), but this interdependence may become particularly problematic when the different departmental goals are incompatible (St. John & Hall, 1991).

Because of the value of cooperative goals for coordination, managers want to …
