Adaptive Estimation Of Autoregressive Models With Time-Varying Variances, Ke-Li Xu, Peter C. B. Phillips

Research Collection School Of Economics

Stable autoregressive models are considered with martingale differences errors scaled by an unknown nonparametric time-varying function generating heterogeneity. An important special case involves structural change in the error variance, but in most practical cases the pattern of variance change over time is unknown and may involve shifts at unknown discrete points in time, continuous evolution or combinations of the two. This paper develops kernel-based estimators of the residual variances and associated adaptive least squares (ALS) estimators of the autoregressive coefficients. Simulations show that efficiency gains are achieved by the adaptive procedure.

Unit Root Model Selection, Peter C. B. Phillips

Research Collection School Of Economics

Some limit properties for information based model selection criteria are given in the context of unit root evaluation and various assumptions about initial conditions. Allowing for a nonparametric short memory component, standard information criteria are shown to be weakly consistent for a unit root provided the penalty coefficient Cn?? and Cn/n?0 as n??. Strong consistency holds when Cn/(log logn)3?? under conventional assumptions on initial conditions and under a slightly stronger condition when initial conditions are infinitely distant in the unit root model. The limit distribution of the AIC criterion is obtained.

The Effect Of A Reflex Replication Program On Retained Primary Reflexes, Motor Coordination, Vocabulary, Visual Motor Ability And Rapid Naming In Preprimary Aged Children, Deborah Callcott

Theses: Doctorates and Masters

The link between movement and cognition is not new, but remains steeped in controversy in the educational community. One of the reasons for this controversy has been the lack of substantial research that supports the link between movement programs and observable academic benefits. The results of recent research have indicated that the retention of primary reflexes, particularly the tonic neck reflexes in young children, can result in difficulties that affect the overall functioning of the child. The retainment of reflexes may lead to clumsiness, poor eye hand coordination, poor manipulative skills and consequently academic achievement may be compromised in some …

Dimensions Of Information Technology Governance: A Study Of Theory And Practice, Pui S. Ko

Theses: Doctorates and Masters

The emergence of corporate governance is the response to recent high profile collapses of organisations such as Enron and WorldCom. Because of the ubiquitous nature of Information Technology (IT) and its influence on organisational activities, IT governance is increasingly seen as an integral part of corporate governance. However, existing literature shows the lack of a common understanding of IT governance due to various perspectives held amongst academics and practitioners. For example, schools of thought group IT governance according to structure with an emphasis on control and co-ordination or process with an emphasis on capability and continuity. The purpose of this …

Nonlinear Random Response Of Large-Scale Sparse Finite Element Plate Bending Problems, Swati Chokshi

Civil & Environmental Engineering Theses & Dissertations

Acoustic fatigue is one of the major design considerations for skin panels exposed to high levels of random pressure at subsonic/supersonic/hypersonic speeds. The nonlinear large deflection random response of the single-bay panels aerospace structures subjected to random excitations at various sound pressure levels (SPLs) is investigated. The nonlinear responses of plate analyses are limited to determine the root-mean-square displacement under uniformly distributed pressure random loads. Efficient computational technologies like sparse storage schemes and parallel computation are proposed and incorporated to solve large-scale, nonlinear large deflection random vibration problems for both types of loading cases: (1) synchronized in time and (2) …

Social-Cognitive Biases In Simulated Airline Luggage Screening, Jeremy R. Brown

Psychology Theses & Dissertations

The study examined the role that social-cognitive biases play in decision making processes during airline luggage screening, Participants (n = 96) performed a computer simulated task where they tried to detect hidden weapons in 200 x-ray images of passenger luggage. Participants saw each luggage image for either two seconds (high time pressure) or six seconds (low time pressure). In addition, on each trial, participants observed the pictures of the "passenger" to whom the luggage purportedly belongs. The "pre-anchor group" answered questions about the passenger before the luggage image appears, the "post-anchor" group answered questions after the luggage appears, and the …

Exploring Interactions During Multiorganizational Policy Implementation: A Case Study Of The Virginia Coastal Zone Management Program, Madeleine Wright Mcnamara

School of Public Service Theses & Dissertations

Organizations face implementation challenges compounded by complex and interconnected public problems. In the environmental arena, the inabilities of individual organizations to resolve these problems independently are exacerbated by the scope, duration, and tremendous diversity of tasks coupled with a lack of funding. As a result, multiorganizational arrangements are created as public, private, and nonprofit organizations work together to implement policy. These relationships increase organizational capacities through the diversification of resources and expertise.

Multiorganizational implementation is complicated by various legal authorities, missions, goals, and operational procedures that guide individual organizations. One way to approach these complexities is to expand our understanding …

Corpulent Counter-Publics: Radical Cheerleading And Resignification Of The Fat Body, Emily Dianne Cram

Dissertations and Theses @ UNI

This thesis investigates the power of language, discourse, and symbols in the dominant construction of corpulence, and how it simultaneously constricts subjectivity and offers avenues of resistance and revolt. I focus my analysis on the public protest actions of San Francisco's radical cheerleading troupe The Bod Squad. I argue that The Bod Squad's protest constitutes a counter-public sphere in its rhetorical functions of positive self-representation and public confrontation. Through their protest actions, The Bod Squad stretches dominant ideologies of corpulence to create discursive space for alternative articulations of identities, interests, and needs. This thesis challenges traditional counter-public sphere theory and …

Aging Effects On The Transcription Of Differentially Impaired Dysarthric Speech, Molly Anne Duggan

Dissertations and Theses @ UNI

Thirty participants transcribed 60 words and 30 sentences spoken by persons with dysarthria. Participants, all aged 65 and older were divided into three age groups: Young-Old, Middle-Old, and Old-Old. Each group was comprised of 10 participants. Stimuli were recorded by two male speakers with differing severity levels of dysarthria. Results suggested age did affect the transcription scores, as the Young-Old participants were able to transcribe words and sentences with greater accuracy than the Old-Old participants. The severity of the dysarthric speaker also affected the accuracy of participants in transcribing their words and sentences. Utterances produced by the speaker with mild …
