The Double-Edged Sword Of Mandarin : Language Shift And Cultural Maintenance Among Middle-Aged Chinese-Malaysians, Teresa Wai See Ong, Robert A. Troyer

Manusya, Journal of Humanities

Previous research has demonstrated that the increasing importance of Mandarin in education and public life has led many younger Chinese-Malaysians to regard Mandarin as their mother tongue and part of their cultural identity rather than a heritage language. Fewer studies have documented the language repertoires of middle-aged and older Chinese-Malaysians. This paper presents a qualitative study of Mandarin use conducted with six Chinese-Malaysians aged 40 and older. The participants reported extensive use of Mandarin in the domains of home, work, religion, and cultural maintenance, which were served by a heritage language in the past. This indicates that the use of …

Manusya, Journal of Humanities

The removal of “Phimai, its Cultural Route and the Associated Temples of Phanomroong and Muangtam” from the the World Heritage Tentative List in 2019 indicates the change of focus of the Thailand State Party away from this emsemble originally included as components of the Phimai cultural route. This paper discusses the reasons behind this change, the values and ouv as well as advantages and disadvantages of these two proposals in the context of World Heritage nomination. It concludes that the proposal of the Ensemble of Phanom Rung was made after work on nominating the Phimai cultural route faced management obstacles …

Who, Or What, Is Lost : Singapore’S Impressions Of Christmas Island, C. 1960–1990, Ying-Kit Chan

Manusya, Journal of Humanities

Although Singapore no longer governs Christmas Island, either on behalf of its British colonial administrators or for itself, some Singaporeans continue to regard it as a lost territory and have false impressions that it once belonged and should again belong to Singapore. By examining this complexity related to Christmas Island and its possible implications for Singapore’s national psyche, this paper surveys the newspapers of Singapore and oral history records of Singaporean ministers and officials for accounts of Christmas Island. It suggests that Singaporean newspapers’ portrayal of Christmas Island as a neglected Australian overseas territory contributed to some Singaporeans’ perception that …

Identification And Characterization Of Transcription Factors Regulating Methionine Gamma-Lyase Gene Expressionin Durian Durio Zibethinus M. Pulps, Pinnapat Pinsorn

Chulalongkorn University Theses and Dissertations (Chula ETD)

Durian (Durio zibethinus L.) is an economic fruit crop in Southeast Asia. In Thailand, more than 200 durian varieties are found. Among them, two commercial cultivars which are Chanee and Monthong are mainly cultivated. Durian fruit releases a strong sulfuryl odor containing ethanethiol, methanethiol, and hydrogen sulfide during ripening. Methionine γ-lyase (MGL) is an enzyme responsible for α, γ-elimination of L-methionine into methanethiol, ammonia, and α-ketobutyrate. MGL gene is highly expressed in durian pulps during ripening concurring with methanethiol production during ripening. However, the function of durian MGL (DzMGL) has not been characterized. Thus, the enzymatic activity assay towards L-methionine, …

A Call For Congressional Action: Revisiting Universal Jurisdiction In The United States, Alida Soileau

Denver Journal of International Law & Policy

This Comment examines the United States' failure to invoke universal jurisdiction, even when doing so would likely have net positive effects in the foreign policy sphere. Instead, when war criminals turn up in the United States, the government may charge them with immigration offenses relating to their failure to disclose information about their past. Unless the accused is a United States citizen or there is a nexus between their crimes and the United States, the government will not prosecute jus cogens offenses--offenses so egregious that all of humanity has a duty to prevent and prosecute them, like genocide--unless strict jurisdictional …

Bioinspired Phenolic Compounds For Biomedical Devices, Zhen Tian

Doctoral Dissertations

In this dissertation, I investigated the metal-chelating ability and redox activity of phenoliccompounds from different sources for biomedical applications. Eumelanins are the naturally occurring biopigments that can be found in skin, hair, eyes, or brain of many living organisms. Various functional groups in eumelanin permit it to binding metal ions via comproportionation reaction. I investigated the structure-property relationship of eumelanin by X-ray scattering and electrochemical techniques. I reported the mesoscale structure of eumelanins and its impact on the charge transport. X-ray scattering suggests that eumelanin pigments exhibit the semi-crystalline structure with ordered d-spacings. These unique mesoscale structures further influence the …

The “License As Tax” Fallacy, Jonathan M. Barnett

Michigan Technology Law Review

Intellectual property licenses are commonly portrayed as a “tax” that limits access to technology assets, which in turn stunts innovation by intermediate users and inflates prices for end-users. Renewed skepticism toward IP licensing, and associated judicial and regulatory interventions that apply per se-like liability rules under patent and antitrust law to IP licensing, overlook the fact that IP licenses typically play a “positive-sum” enabling function, rather than a “zero-sum” exclusionary function, by mitigating expropriation risks that would otherwise frustrate transactions between the holders of complementary specialized IP and non-IP assets. As illustrated by paradigm examples of licensing and other IP-dependent …

Adapting Ripple Effect Mapping To A Virtual Survey Format, Matthew D. Greene, Jessica Stroope, Denise Holston

Faculty Publications

Community development projects continue despite the COVID-19 pandemic. Participatory evaluation of these projects is crucial. Ripple effect mapping (REM) is a participatory approach to evaluation that captures coalition and community member perspectives on program outcomes and impacts. In response to COVID-19, the Louisiana State University AgCenter Healthy Communities Initiative adapted REM for online delivery. The REM evaluation was found to be an effective way for community coalitions to reflect on outcomes and impacts and to motivate continued engagement

A New Species Of New Guinea Worm-Eating Snake (Serpentes, Elapidae, Toxicocalamus Boulenger, 1896) From Western Highlands Province, Papua New Guinea, Jackson R. Roberts, Bulisa Iova, Christopher C. Austin

Faculty Publications

We describe a new species of New Guinea Worm-Eating Snake (Elapidae: Toxicocalamus) from a specimen in the reptile collection of the Papua New Guinea National Museum and Art Gallery. Toxicocalamus longhagen sp. nov. can be easily distinguished from other species of this genus by the presence of paired subcaudals, a preocular scale unfused from the prefrontal scale, a prefrontal distinct from the internasal scale that contacts the supralabials, a single large posterior temporal and two postocular scales. The new taxon is currently known only from one specimen, which was collected from Mt. Hagen Town in Western Highlands Province, Papua New …

Gis-Automated Delineation Of Hospital Service Areas In Florida: From Dartmouth Method To Network Community Detection Methods, Changzhen Wang, Fahui Wang

Faculty Publications

Since the Dartmouth Hospital Service Areas (HSAs) were proposed three decades ago, there has been a large body of work using the unit in examining the geographic variation in health care in the U.S. for evaluating health care system performance and informing health policy. However, many studies question the replicability and reliability of the Dartmouth HSAs in meeting the challenges of an ever-changing and a diverse set of health care services. This research develops a reproducible, automated, and efficient GIS tool to implement Dartmouth method for defining HSAs. Moreover, the research adapts two popular network community detection methods to account …

Moral Emotions And Unnamed Wrongs: Revisiting Epistemic Injustice, Usha Nathan

Faculty Publications

Current discussions of hermeneutical injustice, I argue, poorly characterise the cognitive state of victims by failing to account for the communicative success that victims have when they describe their experience to other similarly situated persons. I argue that victims, especially when they suffer moral wrongs that are yet unnamed, are able (1) to grasp certain salient aspects of the wrong they experience and (2) to cultivate the ability to identify instances of the wrong in virtue of moral emotions. By moral emotions I mean emotions like indignation that reflect an agent’s ethical commitments and bear on her ethical assessments. Further, …

Transformed Estimation For Panel Interactive Effects Models, Cheng Hsiao, Zhentao Shi, Qiankun Zhou

Faculty Publications

We propose a transformed estimator for the slope coefficients of panel models with interactive effects. The transformed estimation method does not require the prior knowledge of the dimension of factor structure. It is consistent and asymptotically normally distributed under fairly general conditions when N is fixed and (Formula presented.) or T is fixed and (Formula presented.) or when both N and T are large and (Formula presented.) Moreover, because the transformation is equivalent to aggregating cross-sectional units or time units before implementing the least-square method over time or across cross-sectional units, it can bypass the issues arising from heteroscedasticity across …

Forecasting Equity Index Volatility By Measuring The Linkage Among Component Stocks∗, Yue Qiu, Tian Xie, Jun Yu, Qiankun Zhou

Faculty Publications

The linkage among the realized volatilities of component stocks is important when modeling and forecasting the relevant index volatility. In this article, the linkage is measured via an extended Common Correlated Effects (CCEs) approach under a panel heterogeneous autoregression model where unobserved common factors in errors are assumed. Consistency of the CCE estimator is obtained. The common factors are extracted using the principal component analysis. Empirical studies show that realized volatility models exploiting the linkage effects lead to significantly better out-of-sample forecast performance, for example, an up to 32% increase in the pseudo R2. We also conduct various forecasting exercises …

Measuring Impact Of New Teacher Mentoring Programs Through Teacher Sense Of Efficacy Scale, Ezzard Beane

Electronic Theses and Dissertations

The education gap between economically advantaged and economically disadvantaged students in the United States is accountable for most of the education gap in the United States and other technologically advanced countries. Unfortunately, the students who require the most academic support and quality instruction often receive instruction from the least qualified. The gap in effective instruction for the economically disadvantaged is related to the quality of instruction which is often facilitated by the least effective and least qualified teachers. The quality of teachers is directly related to the high teacher attrition rates of teachers serving economically disadvantaged students. Maximizing strategies to …

Synthesis And Charecterisation Of Methylene Blue Derivatives, Rohit Alluri

Electronic Theses and Dissertations

Since its discovery, the fluorescent dye known as methylene blue has been employed in a variety of scientific disciplines. Methylene blue (MB) for intraoperative fluorescence imaging has only lately been employed. 10-N-carbamoyl linkage modification of Methylene blue helps us in developing compounds with off-to-on fluorescence switch in the presence of near infrared (NIR). Due to its naturally induced photodamage to normal tissues and deeper penetration of lesion regions when compared to UV and visible light, near infrared (NIR) light is considered favorable among the broad radiation range. The previously synthesized derivatives are not completely soluble in water, they require other …

The Role Of Technology: Graduate Students' Experiences In An Ed.D. Program, Veronica C. Crawford

Electronic Theses and Dissertations

This study contributes to our understanding of online learning in a graduate program – the Doctor of Education (Ed.D.) – designed to prepare practitioners to impact their local contexts, practices, and communities. Online learning is one of the fastest-growing trends in the instructional use of technology (Means, Toyama, Murphy, & Baki, 2013; Nguyen, 2015). However, the literature is scant on how graduate students learn in technology-rich environments. This study aimed to explore how graduate students perceive the online learning environment in an Ed.D. program at a public, not-for-profit research institution in the United States. Unequivocally, online education is ubiquitous. However, …

Development Of Hydroxyl Radical Protein Footprinting For Challenging Systems, Zhi Cheng

Electronic Theses and Dissertations

Structural biology plays an important role in modern molecular biosciences. High-resolution hydroxyl radical protein footprinting (HR-HRPF) is a mass spectrometry (MS) based method for analyzing protein topography at a spatial resolution from peptide up to the individual amino acids. Fast photochemical oxidation of protein (FPOP) is an HRPF technique that generates hydroxyl radicals by UV laser-induced photolysis of hydrogen peroxide. FPOP coupled with MS technology has successfully elucidated protein structure information, protein-protein interaction, and protein allosteric or conformational change. Even though FPOP coupled MS has quickly had a large impact on the field of biopharmaceutical analysis, serious limitations still remain. …

Cellular Mechanisms Of Igf-1 Neuroprotection After Ischemic Stroke, Cellas A. Hayes

Electronic Theses and Dissertations

Strokes are a leading cause of mortality and disability worldwide; thus, there is a dire need for new, effective pharmacotherapeutics that can be administered to reduce the burden of disease post-insult. Clinical findings have shown that insulin-like growth factor-1 (IGF-1) levels and post-stroke functional outcomes exhibit a positive relationship. Importantly, the administration of exogenous IGF-1 in rodent models of ischemic stroke attenuates neurological damage and functional deficits following stroke. Ongoing stroke damage after the initial insult is primarily induced by increased extracellular glutamate causing substantial neuronal death, increased neuro-inflammation, and leading to greater tissue loss. Evidence from our laboratory has …
