Content, Values, And Environment: Applicant Reactions To Job Descriptions, Adria D. Toliver Jan 2010

Content, Values, And Environment: Applicant Reactions To Job Descriptions, Adria D. Toliver

Psychology Theses - Archive

The research on job descriptions is limited and information regarding applicant reactions to job descriptions is even scarcer. The current research hypothesized that after reading job content information, an applicant's decision to apply or not apply for a job rests on the organizational values and work environment information included in the job description. Participants were presented with four job descriptions with varying levels of job content, organizational values, and work environment information and were asked to indicate which description would make them most and least likely to apply for the job and why. The results showed that the job description …

False And Veridical Memories And Stereotype Threat: A Cognitive Understanding Of A Social Phenomenon, John R. Biggan Jan 2010

False And Veridical Memories And Stereotype Threat: A Cognitive Understanding Of A Social Phenomenon, John R. Biggan

Psychology Theses - Archive

In 1995, Steele and Aronson found that when asked to simply indicate their race prior to a memory test (Study 4) black participants performed significantly worse on a memory test than when not asked to indicate their race. However, their white counterparts did not show a decrease in performance. This effect is often referred to as stereotype threat. The effect has been replicated using various tests of general memory and even sporting performance (Beilock & McConnell, 2004). In the cognitive literature memory processes are often broken down into two processes, referred to as recollection and familiarity. Recollection is best understood …

Cuspidal Modules Of The Lie Superalgebras Osp(1|2n), Alekzander J. Malcom

Mathematics Theses - Archive

The classification of all bounded weight modules for the classical Lie superalgebras is an open question. Only recently, in fact, has the question been closed for the Lie algebras (see Mathieu). We give a differential algebra isomorphic to osp(1|2n), which is one of the remaining Lie superalgebras to have its modules classified. We also conjecture, following the results for the Lie algebra sp(2n), a method to finalize the classification for osp(1|2n).

Selective Cross Correlation In Passive Timing Analysis Attacks Against Low-Latency Mixes, Titus Abraham Jan 2010

Selective Cross Correlation In Passive Timing Analysis Attacks Against Low-Latency Mixes, Titus Abraham

Computer Science and Engineering Theses - Archive

A mix is a communication proxy that hides the relationship between incoming and outgoing messages. Routing traffic through a path of mixes is a powerful tool for providing privacy. When mixes are used for interactive communication, such as VoIP and web browsing, attackers can undermine user privacy by observing timing information along the path. Mixes can prevent these attacks by inserting dummy packets (cover traffic) to obfuscate timing information in each stream. Two recently proposed defenses, defensive dropping and adaptive padding, enhance cover traffic by ensuring that timing information seen at the sender is very different from that seen at …

Improving Privacy And Performance In Anonymous Communications, Nayantara Mallesh Jan 2010

Improving Privacy And Performance In Anonymous Communications, Nayantara Mallesh

Computer Science and Engineering Dissertations - Archive

Anonymous communications systems provide an important privacy service by keeping passive eavesdroppers from linking communicating parties. However, an attacker can use long-term statistical analysis of traffic sent to and from such a system to link senders with their receivers. While it is important to protect anonymous systems against such attacks, it is also important to ensure they provide good performance. In this thesis, we aim to make contributions to both these areas.In the statistical disclosure attack (SDA), an eavesdropper isolates his attack against a single user, whom we call Alice, with the aim of exposing her set of contacts.

Measuring Named Entity Similarity Through Wikipedia Category Hierarchies, Jared M. Ashman Jan 2010

Measuring Named Entity Similarity Through Wikipedia Category Hierarchies, Jared M. Ashman

Computer Science and Engineering Theses - Archive

Identifying the semantic similarity between named entities has many applications in NLP, including information extraction and retrieval, word sense disambiguation, text summarization and type classification. Similarity between named entities or terms is commonly determined using a taxonomy based approach, but the limited scalability of existing taxonomies has led recent research to use Wikipedia's encyclopedic knowledge base to find similarity or relatedness. These existing methods using Wikipedia have so far focused on relatedness, but are not as well suited to finding similarity. In this thesis, we evaluate methods for determining the semantic similarity between named entities by associating each named entity …

Multi-Wavelength All-Optical 2r Regeneration, Pallavi Govind Patki

Electrical Engineering Dissertations - Archive

We experimentally demonstrate, for the first time to our knowledge, simultaneous all-optical 2R regeneration of multiple WDM channels. In the recent work [1], our group has proposed an all-optical 2R regeneration scheme capable of handling multiple WDM channels simultaneously. Our proposed multi-channel regenerator is a modified configuration of Mamyshev's 2R regenerator [2], in which a conventional highly-nonlinear-fiber (HNLF) is replaced by a novel dispersion-managed nonlinear medium. The proposed multi-channel regeneration scheme uses multiple concatenated dispersion-managed sections, where each dispersion-managed section contains a piece of HNLF and a periodic-group-delay device (PGDD). For the proof-of-principle demonstration of the regenerator we have built …
