A Comparison Between The Verbal Interruptions By Speakers Of English As A Lingua Franca (Elf) And Speakers Of English As A Native Language (Enl), Yue Yuan Li

Lingnan Theses

Previous research focused primarily on how interruptions vary according to social factors in situations where English is the native language for all speakers (see Menz and Al-Roubaie, 2008; O‟Reilly, 2008; West and Zimmerman, 1983; Zimmerman and West, 1975). Little has been done on interruptions in situations where English is used as a lingua franca. The purpose of this research is to 1) provide conversational evidence on how experienced ELF speakers make interruptions, 2) explore functions of interruptions in ELF communication; 3) compare the types and functions of interruptions in ELF communication with those in ENL communication; 4) compare the types …

Do Analyst Earnings Beta Explain Growth Anomaly?, Sophie Phuong Thanh Doan

Dissertations and Theses Collection (Open Access)

Using a measure of cashflow risk derived from analyst forecasts, I find that cashflow risk offers a partial explanation for the value – growth anomaly. In particular, the lowest asset growth portfolio has a higher earnings beta than the highest asset growth portfolio. Approximately cashflow risk measured by earnings beta carries a significant positive risk premium of 1.24% with a t-value of 3.51.

Corporate Governance And Earnings Management Before Share Repurchase Announcements In Singapore, Jian Ming Chua

Dissertations and Theses Collection (Open Access)

Share repurchase in Singapore was legalized in 1998. It is well known that investors view share repurchase as good news. This study is based on share repurchase announcements from 2006 to 2009. The mean Cumulative Market-Adjusted Returns (CAR) for the period [0, +1] and [-1, +1] are significant at 1.25% and 1.33% respectively. In Singapore, there are positive abnormal returns following share repurchase announcements in support of the ―free cash flow‖ hypothesis. By using the Singapore Corporate Governance Index as a proxy, the weakly governed companies exhibit the strongest, positive and significant CAR of 2.62% for the period [0, +1]. …

Auditor Choice, Audit Fees And Internal Governance In Family Firms, Shaohua He

Lingnan Theses

I study the role of auditing in mitigating agency concerns in family firms. Family firms face less severe agency problems due to the separation of ownership and control (Type 1) but more severe agency problems between controlling and noncontrolling shareholders (Type 2). As family firms make up a large part of most free enterprise economies it is important to examine these two agency problems with respect to auditor choice and audit effort. I find that family firms are more likely to choose a specialist auditor than nonfamily firms, consistent with the argument that family firms need to signal their non-expropriating …

Fragmented Authoritarianism And Politics Of Hydropower In China : Case Studies Of Tgp & Nrp, Miu Fai, Tommy Wong

Lingnan Theses

Thanks for economic improvements since the ‘open-door policy’ in 1978; China’s international status has been improving economically and even politically. For instance, she has become a major contributor of BRIC which is a group of four most rapidly developing countries in the world, i.e. Brazil, Russia, India and China, and the largest buyer of U.S. treasury bonds in the world. Nevertheless, a number of intellectuals like Liu and Shirk pointed out that there are still a number of difficulties – both exogenous and endogenous – underneath.1 This research would like to concentrate on one of the aspects which Chinese investigators …

Auditor Type, Firm Ownership And Auditor Reporting Under A Joint Audit Requirement : Exploratory Evidence From India, Ting Zou

Lingnan Theses

India is one of the largest developing countries in the world. Although many issues and phenomena arising from its transitional economy are worthy of research from an accounting perspective, the Indian accounting market is a field that remains relatively unexplored in the extant literature. One of the institutional features of India is that while it is mandatory for public sector companies and banks to have joint auditors, their appointment is voluntary for other companies. In a thesis motivated by this and other institutional features and the absence of related accounting and auditing studies conducted in an Indian setting, I examine …

The Effects Of Perceived Brand Globalness On Consumer Responses To Brand Failures, Xue Gao

Lingnan Theses

Even big companies cannot guarantee their brands never ever fail customers. Recently the brand failures of Toyota taught us a vivid lesson that a brand takes decades to be built up but to be ruined overnight. Although, the advantages of building global brands are well recognized in literature, the superiorities of global brands in brand failure context are not yet studied. This study aims to investigate the effects of perceived brand globalness (PBG) on consumer affective and behavioral responses to brand failures. Global brands are perceived superior to local brands due to factors like higher quality perceptions and prestige feelings. …

Goal Interdependence And Conflict Management For Government And Business Collaboration In China, Xinru Wu

Lingnan Theses

This study empirically examines the dynamics and conditions of conflict managing approaches on government and business collaboration. It posits that conflict for mutual benefit critically effects government and business collaboration outcomes. This study adopts Deutsch’s (1973) theory of goal interdependence to understand when and how government officials and business managers adopt the mutually beneficial conflict approach. It proposes that cooperative goals between government officials and business managers promote the mutually beneficial conflict approach and reduce win-lose competitive conflict and avoiding conflict.

A total of 101 interviews were conducted in China in 2009. Results of structural equation modeling and other analyses …

Enhancing Green Tax Measures In Hong Kong : A Means Of Addressing The City's Environmental Problems, Yuzhu Lu

Lingnan Theses

Nowadays, pressures on the environment are increasing around the world. In particular, Hong Kong, a compact city with a population of nearly seven million, one which has undergone remarkable economic growth over the past few decades, has developed severe environmental problems. It also has deficiencies in its taxation system: a small tax base, for example. In today’s world, “green” taxes have been accepted and applied by more and more countries, especially those in the OECD. However, Hong Kong still has not adequately used the tax tool as an integral part of the government’s anti-pollution strategy. Accordingly, the major objective of …

Consequences Of Increased Cd45ra And Rc Isoforms For Tcr Signaling And Peripheral T Cell Deficiency Resulting From Heterogeneous Nuclear Ribonucleoprotein L-Like Mutation, Zuopeng Wu, Adele L. Yates, Gerard F. Hoyne, Christopher C. Goodnow

Health Sciences Papers and Journal Articles

CD45 is the most abundant protein tyrosine phosphatase in the plasma membrane of T cells and serves a critical role in TCR signaling. Different CD45 isoforms are made by alternative mRNA splicing depending on the stage of T cell development and activation, yet their role remains unclear. Expression of CD45RA and RC isoforms is increased 20- to 200-fold on T cells from thunder mice with a loss-of-function mutation in the RNA-binding protein, heterogeneous nuclear ribonucleoprotein L-like (hnRNPLL), although total CD45 expression is unaltered. In this study, we test the hypothesis that this shift in CD45 isoform expression alters TCR signaling, …

Issues In Validity Generalization The Criterion Problem, Raquel Hodge

Electronic Theses and Dissertations

Schmidt and Hunter‟s validity generalization model poses seven sources of error variance affecting validation studies. Of the seven sources of error variance, only four sources have been tested. This study looks at an additional source of error variance, the difference between studies in the amount and kind of criterion contamination and deficiency, as proposed by Schmidt and Hunter. The current study proposes a method of evaluating criterion contamination and deficiency in criterion measures in order to minimize their effects on the relationship between criterion and predictor measures. Two unique criteria are used including a traditional subjective measure of current performance …

Developing diagnostic modalities that utilize nanomaterials and miniaturized detectors can have an impact in point-of-care diagnostics. Diagnostic systems that (i) are sensitive, robust, and portable, (ii) allow detection in clinical samples, (iii) require minimal sample preparation yielding results quickly, and (iv) can simultaneously quantify multiple targets, would have a great potential in biomedical research and public healthcare. Bacterial infections still cause pathogenesis throughout the world (Chapter I). The emergence of multi-drug resistant strains, the potential appearance of bacterial pandemics, the increased occurrence of bacterial nosocomial infections, the wide-scale food poisoning incidents and the use of bacteria in biowarfare highlight the …

An Assessment Of Sea Turtle Nesting Behavior In Relation To Hurricane- And Restoration-Induced Beach Morphodynamics, Tonya Michele Long

Electronic Theses and Dissertations

Coastal habitats are highly dynamic and vulnerable to landscape-level disturbances such as storms and restoration projects. Along the east coast of Florida these areas are particularly valuable as they provide significant nesting habitat for two sea turtle species, the threatened loggerhead (Caretta caretta) and the endangered green turtle (Chelonia mydas). This coast was heavily impacted by three major hurricanes in 2004 and in some areas by large restoration projects in 2005. Recent remote sensing methods allow for broad evaluation of the shoreline and thus the ability to assess sea turtle nesting habitat at a landscape scale. I collected nesting data …

The Impact Of Teacher Incentive Pay Programs On The Learning Gains Of Low-Performing Middle School Students, Donna W. Miller

Electronic Theses and Dissertations

President Barack Obama committed hundreds of millions of dollars to the Teacher Incentive Fund (TIF), yet a few fundamental questions remain unanswered—was the federal program effective? Did student test scores improve? Since the late 19th century, teachers have been paid for their classroom services regardless of how well—or poorly— their students performed. Nearly a century later, advocates of education reform continue to champion teacher compensation policies that link salary to student achievement. Researchers have identified two motivation theories that must be present in order to have a successful incentive pay program: goal theory and expectancy theory. The presence or absence …

Sexual Dimorphism Of The Posterior Pelvis Of The Robert J. Terry Anatomical Collection And The William M. Bass Donated Skeletal Collection, Lauren M. Novak

Electronic Theses and Dissertations

Studies of sexual dimorphism of the sacrum have generally been conducted as part of broader population research or on living persons and cadavers, making the anthropological literature sparse. The greater sciatic notch and the preauricular sulcus of the ilium have both been found to show sexual dimorphism, although studies of these traits often have ambiguous definitions of characteristics and lack the standardization of measurements. This research was designed to reexamine and test the accuracy of standard scoring systems and measurements of the posterior pelvis used to determine sex and to establish new formulae combining traits and measurements to accurately determine …

Geographic Variation In Post-Mating Immune Gene Expression In Drosophila Melanogaster, Cheryl Ann Pinzone

Electronic Theses and Dissertations

An organism's immune response may vary due to pathogen pressure in its environment, as well as due to interactions with other organisms. These factors, along with geographic rules (i.e. Gloger's rule) may influence the geographic distribution of the immune response within populations of a species. Here we use real-time quantitative PCR to measure the immune gene expression in six populations collected along the eastern U.S. of Drosophila melanogaster after mating. Antimicrobial genes did not show significant differences in expression due to location, whereas we did observe differences in anti-fungal and pro-phenoloxidase (anti-macromolecule) related genes. These differences in anti-macromolecule resistance are …

Assessing The Psychometric Properties Of The Counseling Competencies Scale A Measure Of Counseling Skills, Dispositions, And Behaviors, Jacqueline Melissa Swank

Electronic Theses and Dissertations

Ethical and competent professional counselors are needed to provide quality counseling services to the public. Counselor educators and supervisors have the responsibility of training competent counselors. Furthermore, counselors and counselors-in-training have the responsibility of continually assessing their own development and implementing measures to increase their competency. Assessment instruments have sought to measure counseling competencies through evaluating counseling skills. However, a paucity of research exists that examines counseling competencies in a comprehensive manner using a psychometrically sound approach. Therefore, a need exists for a psychometrically sound assessment instrument that measures the construct of counseling competencies in a holistic manner. Thus, the …

Effects Of A Treatment Using Computer Generation Of Isometric And Orthographic Projections On Middle School Students' Spatial Ability, Adam Michael Traas

The secondary focus of this study investigates the relationships between mathematical achievement, problem solving preferences, and spatial ability. The secondary focus was tested on a subsample (n=41), with the problem solving preferences measured via the Mathematical Processing Instrument (MPI) (Suwarsono, 1982). Findings indicated no significant gains in spatial ability scores after students’ use of the …

Electroconvulsive Shock Ameliorates Disease Processes And Extends Survival In Huntington Mutant Mice, Akanksha Baharani

Electronic Theses and Dissertations

Huntington's disease (HD) is a devastating autosomal dominantly inherited neurological disorder caused by an abnormal expansion of CAG trinucleotide repeats in the gene coding for the Nterminal region of the huntingtin (Htt) protein, which leads to the formation of a polyglutamine stretch. The greater the CAG repeats, the earlier the onset of the disease. The polyglutamine stretch destabilizes the Htt protein leading to misfolding, abnormal processing, aggregation, and inclusion formation. Mutant Htt protein is believed to damage and kill neurons in the striatum by a mechanism involving increased oxidative and metabolic stress, and impaired adaptive cellular stress responses. A large …

Job Satisfaction And Values Of Counselors In Private Practice And Agency Settings, Laura Cunningham

Electronic Theses and Dissertations

Counselors can work at a variety of locations (Vacc & Loesch, 2000). Yet very little is known about each setting (King, 2007) and what type of counselors would have an optimum fit. Burnout is a pervasive issue in counseling (Lawson, 2007) and providing good-fit information could lessen turnover and burnout from the counseling field. The primary purpose of this study included investigating the differences between job satisfaction and value priorities of counselors in private practice and agency settings. The overarching theoretical framework included Frank Parsons‘ counselors, with seventy-two agency counselors and sixty-three private practitioners. Counselors completed two assessments and a …

The general goal of this dissertation is to provide a comprehensive description of the limitations of established theories on bound electronic nonlinearities in direct-gap semiconductors by performing various experiments on wide and narrow bandgap semiconductors along with developing theoretical models. Nondegenerate two-photon absorption (2PA) is studied in several semiconductors showing orders of magnitude enhancement over the degenerate counterpart. In addition, three-photon absorption (3PA) is studied in ZnSe and other semiconductors and a new theory using a Kane 4-band model is developed which fits new data well. Finally, the narrow gap semiconductor InSb is studied with regard to multiphoton absorption, free-carrier …

Search For Gas Giants Around Late-M Dwarfs, Rohit Deshpande

Electronic Theses and Dissertations

We carried out a near-infrared radial velocity search for Jupiter-mass planets around 36 late M dwarfs. This survey was the first of its kind undertaken to monitor radial velocity variability of these faint dwarfs. For this unique survey we employed the 10-m Keck II on Mauna Kea in Hawaii. With a resolution of 20,000 on the near-infrared spectrograph, NIRSPEC, we monitored these stars over four epochs in 2007. In addition to the measurement of relative radial velocity we established physical properties of these stars. The physical properties of M dwarfs we determined included the identification of neutral atomic lines, the …

Silicon-Sensitized Erbium Excitation In Silicon-Rich Silica For Integrated Photonics, Oleksandr Savchyn

Electronic Theses and Dissertations

It is widely accepted that the continued increase of processor performance requires at least partial replacement of electronic interconnects with their photonic counterparts. The implementation of optical interconnects requires the realization of a silicon-based light source, which is challenging task due to the low emission efficiency of silicon. One of the main approaches to address this challenge is the use of doping of silicon based matrices with optical centers, including erbium ions. Erbium ions incorporated in various hosts assume the trivalent state (Er3+) and demonstrate a transition at 1.54 μm, coinciding with optical transmission windows in both silicon and silica. …

Acetazolamide-Induced Decrease Of Apical Fluid Flow In Choroid Plexus Is Independent Of The Concomitant Changes In Aquaporin-1 Expression, Pouya Alexander Ameli

Electronic Theses and Dissertations

Acetazolamide (AZA), the only drug approved for treatment of hydrocephalus, is effective in only 25-30% of patients while its effect on fluid flow in the choroid plexus (CP) is unknown. The drug reversibly inhibits Aquaporin 4 (AQP4), the most highly expressed „water pore‟ in the brain, and it is postulated that it reduces cerebrospinal fluid (CSF) production by modulating AQP1 (mostly found in the apical membrane of the CP). In this study, we sought to elucidate the effect of AZA on AQP1 and fluid flow in CP. Primary CP culture from p10 Sprague-Dawley rats and TRCSF-B cell line were grown …

Supporting A Standards-Based Teaching And Learning Environment A Case Study Of An Expert Middle School Mathematics Teacher, Didem Akyuz

Electronic Theses and Dissertations

Although it has been more than 20 years since the publication of Curriculum and Evaluation Standards for School Mathematics (NCTM, 1989) and 10 years since the second version of standards, Principles and Standards for School Mathematics (NCTM, 2000), the research underlines the lack of essential practices for standards-based teaching (Franke, Kazemi, & Battey, 2007). The literature also emphasizes the importance of planning in standards-based teaching, although few studies focus on the direct planning of the teacher (Kilpatrick, Swafford, & Findell, 2001). The aim of the current study was to conduct a case study to extract the planning and classroom practices …

Design, Synthesis And Characterization Of New Two-Photon Absorbing (2pa) Fluorescent Dyes And Bioconjugates, And Their Applications In Bioimaging, Carolina D. Andrade

Electronic Theses and Dissertations

The development of new multiphoton absorbing materials has attracted the attention of researchers for the last two decades. The advantages that multiphoton absorbing materials offer, versus their one-photon absorbing counterparts, rely on the nature of the nonlinearity of the absorption process, where two photons are absorbed simultaneously offering increased 3D resolution, deeper penetration, and less photobleaching and photodamage as a result of a more confined excitation. The applications of efficient two-photon absorbing materials have been extensively expanding into the fields of photodynamic therapy, microscopy, and optical data storage. One of the fields where an increased interest in multiphoton absorbing materials …

Clinical Practice Guidelines For Emerging Ultrasound Applications Drafting For Validity And Usability, Kathi Keaton Borok

Electronic Theses and Dissertations

Clinical practice guidelines (CPGs) are viewed by many people with interests in health care as valuable tools for reducing practice variations that undermine patient outcomes and increase medical costs. However, guidelines themselves vary in quality. Assessment tools generally base quality measures on strength of guidelines' evidence base, but particularly for newly emerging applications of ultrasound, standards for measuring guideline quality are controversial. The validity of a guideline is considered likely when strong research-based evidence supports its recommendations, but for newer medical procedures such as emerging ultrasound applications, available evidence is sparse. Existing assessment tools must be modified if they are …

The Academic Word List Reorganized For Spanish-Speaking English Language Learners, Robert W. Bushong Ii

Electronic Theses and Dissertations

Published in TESOL Quarterly a decade ago, the Academic Word List (AWL) (Coxhead, 2000) has become increasingly influential in the field of TESOL. With more than 82% of the AWL comprised of words of Latin and Greek, much of this important list logically consists of English-Spanish cognates because Spanish originated from Latin. In order to serve Spanishspeaking English language learners (SSELLs) better, their teachers need to know which AWL words are cognates. Using published sources and linguistic analysis of the 570 items in the AWL, the research in this thesis has resulted in a newly reorganized AWL divided into four …
