The Effect Of Code Obfuscation On Authorship Attribution Of Binary Computer Files, Steven Hendrikse Jan 2017

The Effect Of Code Obfuscation On Authorship Attribution Of Binary Computer Files, Steven Hendrikse

CCAC Theses and Dissertations

In many forensic investigations, questions linger regarding the identity of the authors of the software specimen. Research has identified methods for the attribution of binary files that have not been obfuscated, but a significant percentage of malicious software has been obfuscated in an effort to hide both the details of its origin and its true intent. Little research has been done around analyzing obfuscated code for attribution. In part, the reason for this gap in the research is that deobfuscation of an unknown program is a challenging task. Further, the additional transformation of the executable file introduced by the obfuscator …

Supporting Education For Students With Children Through Mobile Technology, Brenda C. Varner Jan 2017

Supporting Education For Students With Children Through Mobile Technology, Brenda C. Varner

CCAC Theses and Dissertations

The original goal of this project was to build a peer e-mentoring program for parents and measure the effect of the program on persistence. In spite of strong mentor participation, two terms of focused recruiting did not attract mentees. This sparked the question of why those who had successfully navigated the higher education system thought a peer e-mentoring program was needed but those in the process did not. A focused ethnography was designed to try to understand why students with children were resistant to peer e-mentoring. Students with children used technology to integrate the various roles of life. They used …

Enhanced Prediction Of Network Attacks Using Incomplete Data, Jacob D. Arthur Jan 2017

Enhanced Prediction Of Network Attacks Using Incomplete Data, Jacob D. Arthur

CCAC Theses and Dissertations

For years, intrusion detection has been considered a key component of many organizations’ network defense capabilities. Although a number of approaches to intrusion detection have been tried, few have been capable of providing security personnel responsible for the protection of a network with sufficient information to make adjustments and respond to attacks in real-time. Because intrusion detection systems rarely have complete information, false negatives and false positives are extremely common, and thus valuable resources are wasted responding to irrelevant events. In order to provide better actionable information for security personnel, a mechanism for quantifying the confidence level in predictions is …

Effective Teaching In The Eye Of Teacher Educators: A Case Study In A Higher Education, Melek Çakmak, Ülker Akkutay

The Qualitative Report

Attempts to explore teacher educators’ thoughts seem to be meaningful at educational sciences since the number of studies discussing effective teaching and effective teacher at teacher education in the eye of teacher educators are quite limited. Therefore, this study mainly aims to identify the viewpoints of teacher educators in order to discover how they contextualize the concept of effective teaching. For this aim, a case study design, increasingly used in education (Tellis, 1997), is utilized in the study. This method is suitable when the research addresses an explanatory question such as how or why? (Yin, 2004). A questionnaire including open-ended …

A Review Of Present And Alternative Lionfish Controls In The Western Atlantic, Adam Rittermann Dec 2016

A Review Of Present And Alternative Lionfish Controls In The Western Atlantic, Adam Rittermann

HCNSO Student Capstones

Lionfish (Pterois volitans and Pterois miles) are the first recorded invasive piscivore in the Caribbean and have become a threat to native species. As generalist consumers, lionfish have a broad diet and reduce prey and competitor abundance and juvenile recruitment. To confront this problem, this paper serves to review all of the current and alternative future controls available to manage lionfish populations in the Western Atlantic and determine where focus is lacking. Derby and cull efforts are the only management efforts in place and are not effective in their current state as these local events have short-term benefits, …

Coral Recovery On Phase-Shifted Reefs Depend Upon The Type Of Macroalgae Present, Justin N. Voss Dec 2016

Coral Recovery On Phase-Shifted Reefs Depend Upon The Type Of Macroalgae Present, Justin N. Voss

HCNSO Student Theses and Dissertations

The Florida Keys experienced some of the most drastic transitions from coral to macroalgae dominated states, known as phase-or regime-shifts, of any reefs in the Caribbean. Macroalgae on coral reefs lower coral recruitment by deterring coral settlement either directly through competition or indirectly by changing the chemical environment near the benthos. With evidence of species-specific interactions to coral-macroalgae competition, the type of macroalgae on a phase-shifted coral reef might be more important than just identifying a reef transition. To answer this question, I tested the effect of Laurencia intricata (a macroalgae related to the settlement inducing crustose coralline algae) and …

ADAM10 and ADAM17 have been shown to contribute to the acquired drug resistance of HER2-positive breast cancer in response to trastuzumab. The majority of ADAM10 and ADAM17 inhibitor development has been focused on the discovery of compounds that bind the active site zinc, however, in recent years, there has been a shift from active site to secondary substrate binding site (exosite) inhibitor discovery in order to identify non-zinc-binding molecules. In the present work a glycosylated, exosite-binding substrate of ADAM10 and ADAM17 was utilized to screen 370,276 compounds from the MLPCN collection. As a result of this uHTS effort, a selective, …
