Comic : An Exploration Into Computer-Mediated Intercultural Communication, Simone Alder

University of the Pacific Theses and Dissertations

This thesis explores how cultural differences manifest themselves in computermediated intercultural communication (CoMIC). This study particularly looks at the role and use of digital nonverbals (DNVs) and their regulatory functions. The data analyzed is from a global virtual team working together for a period of three months. The grounded theory method has been employed to code the electronic transcript of the team's communication. Furthermore, the participants were surveyed regarding their personal backgrounds, their work, and their perception of the communication processes that took place. The study shows that in an intercultural communication process DNVs are used to avoid intercultural misunderstandings …

In this protocol, synchronization and training are combined into one scheme. The sink node sends two beacons in each slot instead of one. In the training, sensor searching for its location using a binary search scheme. Our simulation results shown less …

Hand-Holding, Brow-Beating, And Shaming Into Compliance, Craig A. Max

Vanderbilt Journal of Transnational Law

Tax authorities and policy planners have a variety of tools at their disposal to create mechanisms to encourage and enforce compliance with revenue collection systems. Traditionally, these mechanisms include the possibility of criminal prosecution as well as civil pecuniary sanctions. Despite the dominate role that prosecution and pecuniary sanctions hold internationally, there exists a range of alternative enforcement mechanisms utilized. The United States has recently started to implement nonpecuniary enforcement devices to achieve policy goals, namely the encouragement of participating with the federal taxing system. This Note attempts to take an initial step into exploring the range of international enforcement …

Novelty, Arousal, And Love: The Mediating Role Of Self -Expansion, Amy Deloyski

All-Inclusive List of Electronic Theses and Dissertations

There is a substantial amount of evidence for a decline in feelings of passionate love across the course of intimate relationships (Aron, Norman, & Aron, 2001). Self-expansion theory (Aron & Aron, 1986) posits that individuals enter into relationships to expand their sense of self and suggests that declines in feelings of passionate love are due to diminished opportunities for expansion with one's partner over time. Previous researchers have been able to create increases in relationship quality by having partners engage in joint participation in novel and arousing activities, which are considered a basis for self-expansion (Aron, et al., 2000). The …

Fouling In Silicon Microchannel Designs Used For Ic Chip Cooling And Its Mitigation, Jeffrey L. Perry

Theses

Particulate fouling studies with alumina and silica dispersions were performed in silicon, rectangular microchannels having hydraulic diameters between 220-225 μm. The particulates used ranged from the colloidal size range up to tens of microns in size (for particle aggregates). Data show for the most part the absence of particle depositions within the microchannels. This is even the case when there is an electrostatic attraction between the particles and the microchannel surface. The primary reason for this is due to the high wall shear stress at the microchannel walls. In contrast, the headers for the microchannels are quite susceptible to particulate …

The Subjectivity Of Effective History And The Suppressed Husserlian Elements In Gadamer’S Philosophical Hermeneutics, Sebastian Luft

Philosophy Faculty Research and Publications

This essay makes two claims. The first, exegetical, point shows that there are Husserlian elements in Gadamer’s hermeneutics that are usually overlooked. The second, systematic, claim takes issue with the fact that Gadamer saw himself in alliance with the project of the later Heidegger. It would have been more fruitful had Gadamer aligned himself with Husserl and the enlightenment tradition. following Heidegger in his concept of “effective history,” Gadamer risks betraying the main tenets of the enlightenment by shifting the weight from subjectivity to effective history as the “agent” in history. This is not a wholesale dismissal of Gadamer’s project, …

Identification And Ranking Of Relevant Image Content, Mustafa I. A. Jaber

Theses

The work in this thesis proposes an image understanding algorithm for automatically identifying and ranking different image regions into several levels of importance. Given a color image, specialized maps for classifying image content namely: weighted similarity, weighted homogeneity, image contrast and memory color maps are generated and combined to provide a perceptual importance map. Further analysis of this map yields a region ranking map which sorts the image content into different levels of significance.

The algorithm was tested on a large database that contains a variety of color images. Those images were acquired from the Berkeley segmentation dataset as well …

Ieee Compliant Double-Precision Fpu And 64-Bit Alu With Variable Latency Integer Divider, Ryan D. Williams

Theses

Together the arithmetic logic unit (ALU) and floating-point unit (FPU) perform all of the mathematical and logic operations of computer processors. Because they are used so prominently, they fall in the critical path of the central processing unit - often becoming the bottleneck, or limiting factor for performance. As such, the design of a high-speed ALU and FPU is vital to creating a processor capable of performing up to the demanding standards of today's computer users.

In this paper, both a 64-bit ALU and a 64-bit FPU are designed based on the reduced instruction set computer architecture. The ALU performs …

Identification Of Trans-Splicing Sites In Leishmania Major Using Probabilistic Methods, Lukas Habegger

Theses

Leishmania major, a member of the Kinetoplastida family, is a primitive protozoan that causes a human disease, called leishmaniases, affecting numerous people worldwide. The identification of new drug targets to combat leishmaniases necessitates a thorough understanding of how genomic instructions are transformed into functional proteins. It requires not only the prediction and categorization of all the genes, but also a profound understanding of their regulation. Much of gene regulation may occur through a process known as frarcs-splicing. Trans-splicing, which is mechanistically similar to cissplicing, is the process of cleaving a large polycistronic transcript into smaller monocistronic components.

The goal of …

Performance Evaluation Of Extended Sparse Linearization In Gf(2) And Gf(28), Tigin Kaptanoglu

Theses

XSL (eXtended Sparse Linearization) is a recent algebraic attack aimed at the Advanced Encryption Standard. In order to shed some light into the behavior of the algorithm, which is largely unknown, we have studied XSL on equation systems with variables interpreted either as bits or bytes. The algorithm solves byte-systems much faster than it does bit-systems, which promts us to suggest that if a more compact representation of equation systems can be found, such as one where the variables are 8-byte blocks, or even a more generalized form of 8n-byte blocks, it may be possible to increase the speed of …
