Reanalysis Of Some Effects Of The Mutual Exclusivity Constraint And Their Operation In Bilingual Children, Marina Kalashnikova

Open Access Theses & Dissertations

This study investigates the operation of the Mutual Exclusivity constraint in two groups of three-year-old children: monolingual Spanish speakers and bilingual Spanish-English speakers. Previous research has yielded controversial findings regarding the differences in the intra-lingual level operation of the constraint in monolingual and bilingual children. This investigation sheds light on the conflicting outcomes of previous studies by proposing that non-linguistic cognitive and processing abilities may account for the effects attributed to the constraint and that there may be observable differences in monolingual and bilingual children in the development of some--but not all--of these abilities. Although, this study yielded no significant …

Health Prognisis Of Electronics Via Power Profiling, Jonathan Amilcar Cervantes

Open Access Theses & Dissertations

The objective of this research is to investigate a new approach for the early detection of latent defects in electronic devices in the field. Reliability is assessed through the non-traditional approach of recording and evaluating the power profile of electronic devices within a deterministic state of operation. Traditionally, measuring the quiescent current (Iddq) of a device has been employed in manufacturing tests to detect defective parts prior to deployment to the field. However, the monitoring of the deterministic power signature (i.e. boot up or during a self-test routine) has never been exploited to monitor the health of a device in …

South Park And Absurd Culture War Ideologies, The Art Of Stealthy Conservatism, Drew W. Dungan

Open Access Theses & Dissertations

South Park serves as an example of satire and parody lampooning culture war issues in the popular media. Since it targets culture war issues, it is relevant to analyze its political and social stance on the issues as presented within. Both extremes in political and social ideology are targeted. Although the program notes an ideological absurdity in extremist points-of-view, the presentation of the issues attempts to create a sense of moderate ideology criticizing both the far left and far right, when in fact, closer analysis provides evidence that South Park serves a stealthy conservative perspective. Stealthy conservatism presents itself as …

Appropriate Prosodic Variation Is Valued By Users, Rafael Escalante-Ruiz

Open Access Theses & Dissertations

Spoken dialog systems today do not vary the prosody of their utterances, although prosody is known to have many useful expressive functions. In a corpus of memory quizzes, I identified eleven dimensions of prosodic variation, each with its own expressive function. I identified the situations in which each was used, and how to detect these situations from the dialog context and the prosody of the interlocutor's previous utterance. I implemented the resulting response rules and had 21 users interact with two versions of the system. Overall they preferred the version in which the prosodic forms of the acknowledgments were chosen …

Top Management Team Heterogeneity, Global Strategic Posture, And Firm Performance: Evidence From Mnes Headquartered Around The World, Adrian Gil

Open Access Theses & Dissertations

This study empirically examines the relationship between top management team (TMT) heterogeneity and firm performance for a sample of multinational enterprises (MNEs) headquartered in 31 countries from across the globe. Utilizing the theoretical perspectives of upper echelons (Hambrick & Mason, 1984) and information processing (Daft, Bettenhausen, & Tyler, 1993; Galbraith, 1973), I hypothesize that global strategic posture, a measure of the intensity of a firm's involvement in the multinational business environment, moderates the relationships between TMT heterogeneity and firm performance. My findings reveal an "enhancing" interaction (Cohen, Cohen, West, & Aiken, 2003: 285-286) between the different TMT heterogeneities investigated and …

"Should I Just Confess?": The Influence Of Perceived Consequences Associated With Confessing On The Likelihood Of True Vs. False Confessions, Allyson Judith Horgan

Open Access Theses & Dissertations

The growing awareness of the problem of false confessions has lead social science researchers to investigate the factors that influence true vs. false confessions. Previous research suggested that minimization and maximization techniques may be interpreted by a suspect as the equivalent of an offer of leniency and a threat of harsher punishment, respectively. The current studies seek to further this literature by distinguishing between minimization and maximization techniques that may or may not influence a suspect's perceptions of the consequences associated with confessing. Results indicate that techniques that manipulate the perceived consequences of confessing increase false confession rates while those …

Un/Commonplaces: Redirecting Research And Curricula In Rhetoric And Writing Studies, Brian J. Mcnely

Open Access Theses & Dissertations

Un/Commonplaces is guided by a broad and fundamental question of inquiry regarding writing and disciplinary research: how can some of the predominant ways that our discipline has approached writing be retheorized to better approximate the complexity of contemporary rhetorical knowledge work? A corollary inquiry explores the resonances with English Studies that persist--and seeks to uncover how they persist--in our field. I argue that we can negotiate such issues by tracing and troubling some of our core disciplinary commonplaces, those commonsense notions and practices too frequently and easily adopted from English Studies and perpetuated within the often tumultuous and hegemonic relationship …

The Effect Of Facial Resemblance On Alibi Credibility And Final Verdicts, Claudia Ochoa

Open Access Theses & Dissertations

The purpose of this study was to examine an extra-legal variable that may affect the credibility of a defendant and the alibi corroborator's testimonies. In this study, the facial appearance of the alibi corroborator was manipulated to resemble the defendant or the trial judge to different degrees using facial morphing software. Participants serving as mock jurors provided verdicts for a trial summary and rated the credibility of an alibi corroborator. It was hypothesized that as the facial resemblance shared between an alibi corroborator and a defendant increased, the less credible the alibi corroborator's testimony would be perceived, resulting in an …

An Enhanced Method For The Existing Bluetooth Pairing Protocol To Avoid Impersonation Attacks, Patricia Aidee Mendoza

Open Access Theses & Dissertations

As the use of the Bluetooth technology in wireless technologies such as computers, cell phones, personal digital assistants (PDAs), printers, digital cameras, PC peripherals, and headphones, among others, has enormously increased during this decade, it has also increased the need of employing a more secure and robust pairing protocol that protects the transfer of information between Bluetooth devices.

The existing Bluetooth pairing protocol starts when a Bluetooth device is set to be in discoverable mode and it is found by another device. After this step is completed, it initiates the pairing procedure by sharing some important device information, then by …
