First Man And Second Woman: Reflections On The Anniversaries Of Apollo 11 And Cruzan, George J. Annas

Faculty Scholarship

THE United States Supreme Court's decision in Cruzan v. Director, Missouri Department of Health marks its thirtieth anniversary in 2020.' This follows closely after the fiftieth anniversary of the Apollo 11 moon landing.² Anniversaries provide an opportunity for reflection and to gain perspective. We can, I suggest, gain deeper insights regarding human life and death by considering these two anniversaries together. Apollo 11 may seem far from Nancy Cruzan-but the discovery of disturbing details about the death of Neil Armstrong, the first man on the moon, is a productive introduction to the topic of death in a modern American …

Spatial Dynamics Of Nest Success In White-Throated Sparrows (Zonotrichia Albicollis), Sarah E. Moore

All-Inclusive List of Electronic Theses and Dissertations

White-throated sparrows ( Zonotrichia albicollis ) exhibit two color morphs that breed disassortatively with each other, creating a rare four-sex system. This polymorphism, linked to an inversion on Chromosome 2, also results in two distinct behavior profiles and alternate reproductive strategies. Males settle in territories with characteristics that optimize their reproductive strategy. Overall, the objective of this project was to investigate nest success over a long time-period (18 years). I first sought to create an interpolated risk map for nest failure, a major cause of decreased reproductive success in both sexes. High-density areas, associated with white males, contained more failed …

Article 152 Of The Singapore Constitution: The Past, Present, And Future Of Multiracial Recognition, Inclusion, And Accommodation, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

The bicentennial commemoration consists of a year-long series of events to mark the 200^th anniversary of the arrival of Sir Stamford Raffles in Singapore on 29 January 1819. The arrival of the British resulted in the creation of Singapore as a free port and marked the economic, physical, and social transformation of the island, which continues today. Yet, the irony is that the bicentennial commemoration also deliberately seeks to shed light and focus on a more distant past: The half-millennia before Singapore was colonialised and when Singapore was known as Temasek and seen as part of the Nusantara.

Characterizing The Composition Of The Pediatric Gut Microbiome: A Systematic Review, Kane E. Deering, Amanda Devine, Therese A. O’Sullivan, Johnny Lo, Mary C. Boyce, Claus T. Christophersen

Research outputs 2014 to 2021

The consortium of trillions of microorganisms that live inside the human gut are integral to health. Little has been done to collate and characterize the microbiome of children. A systematic review was undertaken to address this gap (PROSPERO ID: CRD42018109599). MEDLINE and EMBASE were searched using the keywords: “healthy preadolescent children” and “gut microbiome” to 31 August 2018. Of the 815 journal articles, 42 met the inclusion criteria. The primary outcome was the relative abundance of bacteria at the phylum, family, and genus taxonomic ranks. α-diversity, short chain fatty acid concentrations, diet, 16S rRNA sequencing region, and geographical location were …

‘I’M My Own Boss…’: Active Intermediation And ‘Entrepreneurial’ Worker Agency In The Australian Gig-Economy, Tom Barratt, Caleb Goods, Alex Veen

Research outputs 2014 to 2021

Platform firm in the gig-economy are disrupting work as a social practice, production systems and recasting capital-labour relations. This qualitative study examines worker agency in the Australian food-delivery sector; a segment where platforms actively intermediate both product and labour markets. Within this sector, worker agency poses a potential challenge to platform-organisations; however this study reveals how these platforms’ work organisation and market regulation constrain agency potential. Shaped by the work’s spatio-temporal features, organisational fixes and institutional context, it is shown how food-delivery workers, transiently attached to the labour market, predominantly engage in ‘entrepreneurial agency’ – a low-level agency expression aimed …

Contribution Of Advanced Regeneration Of Pinus Radiata D. Don. To Transpiration By A Fragment Of Native Forest In Central Chile Is Out Of Proportion With The Contribution To Sapwood Area, Don A. White, Richard P. Silberstein, Francisco Balocchi-Contreras, Juan Jose Quiroga, Pablo Ramirez De Arellano

Research outputs 2014 to 2021

The transpiration of Nothofagus glauca (Phil.) Krasser and advanced Pinus radiata D. Don. regeneration was measured in a fragment of native N. glauca forest. Over the eight months of this study, P. radiata contributed approximately 60% of the total stand transpiration. This was out of proportion with the approximately 34% of the stand sapwood area contributed by P. radiata. This was due to the significantly greater sap flux density of the P. radiata compared to the N. glauca between May and October. Though the results are from a small study conducted as part of a larger experiment, it is argued …

How Special Is Special Interest Tourism – And How Special Are Special Interest Tourists? A Perspective Article In A Chinese Context, Jun Wen, Mao-Ying Wu

Research outputs 2014 to 2021

Special interest tourism has emerged as a valuable niche market for tourism destinations in the past decade. However, tourism scholars have generally struggled to answer McKercher and Chan’s [2005. How special is special interest tourism? Journal of Travel Research, 44(1), 21–31] question, ‘How special is special interest tourism?’ Such ambiguity extends to the related enquiry, ‘How special are special interest tourists?’, in attempting to define special interest tourists. This perspective research letter discusses these questions in terms of Chinese outbound tourism. Based upon the reflection of previous research, the authors’ thoughts and ongoing research in this area, knowledge …

Managing Science Teachers’ Adoption Of The 2005 Tanzanian Inquiry And Student-Centred Curriculum: Revealing Schoolbased Leaders’ Practices And Achievements, Noel Mark Makwinya

Theses: Doctorates and Masters

Many countries have made considerable changes to their education systems in response to the forces of globalisation. Tanzania is no exception. The most recent educational change attempt in Tanzania relates to the introduction of the 2005 Tanzanian Inquiry and Student- Centred Curriculum.

Sound change-leadership is a necessary condition for the realisation of change, particularly in influencing its adoption. Within the descriptive qualitative research paradigm, this study employed a Type IV (embedded and multiple) case-study design to examine and describe science teachers’ lived experiences in dealing with this latest Tanzanian curriculum and the role played by school-based leaders in influencing such …

Soul Food: [Re]Framing The African-American Farming Crisis Using The Culture-Centered Approach, Andrew Laurence Carter, Adam Alexander

Faculty Research, Scholarly, and Creative Activity

Historically, African-American farmers faced a long and challenging struggle to own land and operate independently. In recent years, several factors, including unfair policy legislation, institutionalized racism, the mechanization of agriculture, and increases in agricultural technology have exacerbated land loss and decreases in farm ownership. Currently, African-American farmers are vastly underrepresented, comprising just 2% of the nation's farmers, 0.5% of farmland and 0.2% of total agricultural sales. As a site for inquiry, this topic has been examined across many academic sub-disciplines, however, the literature has not yet explored how the erasure of the African-American farmer influences the conversation about broader diet-related …

Faculty Research, Scholarly, and Creative Activity

This paper examines the effect of having a third-party scientific expert present in stakeholder interviews. The study was conducted as part of a larger project on stakeholder engagement for natural resource management in the Verde Valley region of Arizona. We employed an experimental design, conducting stakeholder interviews both with and without an identified scientific expert present. Our sample consisted of 12 pairs of interviewees (24 total participants) who we matched based on their occupation, sex, and spatial proximity. For each pair, the scientific expert was present as a third party in one interview and absent in the other. We used …

Navigating Refugee Subjecthood: Cambodian American Education, Identity, And Resilience, Yvonne Y. Kwan

Faculty Research, Scholarly, and Creative Activity

To investigate trauma formation associated with the intricacy of Cambodian-specific experiences, this study examines how refugee identities and daily diasporic experiences shape the larger subject positions of subsequent generations—particularly through the concept of refugee subjecthood. Cambodia American students’ navigation of ethnic and racial identity reveals that in comparison to the available discursive narratives about their history (given to them through multicultural education), the younger generations’ is an inexact fit. To draw out the relationships between collective feelings and social experiences, this article addresses how Cambodian American students not only come into recognition about their positions as refugee subjects but also …

Spatial Particulate Fields During Highwinds In The Imperial Valley, California, Frank R. Freedman, Paul English, Jeff Wagner, Yang Liu, Akula Venkatram, Daniel Q. Tong, Mohammad Z. Al-Hamdan, Meytar Sorek-Hamer, Robert Chatfield, Ana Rivera, Patrick L. Kinney

Faculty Research, Scholarly, and Creative Activity

We examined windblown dust within the Imperial Valley (CA) during strong springtime west-southwesterly (WSW) wind events. Analysis of routine agency meteorological and ambient particulate matter (PM) measurements identified 165 high WSW wind events between March and June 2013 to 2019. The PM concentrations over these days are higher at northern valley monitoring sites, with daily PM mass concentration of particles less than 10 micrometers aerodynamic diameter (PM10) at these sites commonly greater than 100 μg/m3 and reaching around 400 μg/m3, and daily PM mass concentration of particles less than 2.5 micrometers aerodynamic diameter (PM2.5) commonly greater than 20 μg/m3 and …

Debt In Just Societies: A General Framework For Regulating Credit, John Linarelli

Scholarly Works

Debt presents a dilemma to societies: successful societies benefit from a substantial infrastructure of consumer, commercial, corporate, and sovereign debt but debt can cause substantial private and social harm. Pre- and post-crisis solutions have seesawed between subsidizing and restricting debt, between leveraging and deleveraging. A consensus exists among governments and international financial institutions that financial stability is the fundamental normative principle underlying financial regulation. Financial stability, however, is insensitive to equality concerns and can produce morally impermissible aggregations in which the least advantaged in a society are made worse off. Solutions based only on financial stability can restrict debt without …

Examining The Complex Relationship Between Innovation And Regulation Through A Survey Of Wastewater Utility Managers, Luke Sherman, Alida Cantor, Anita Milman, Michael Kiparsky

Geography Faculty Publications and Presentations

Despite pressures to increase performance and decrease costs, innovation has been slow to emerge in the municipal wastewater sector. The relationship between regulation and innovation in this sector is a particularly interesting aspect of this conundrum, given the degree to which public utility decision-making is influenced by regulation. Using a national survey, this paper examines US wastewater utility managers’ perceptions of how regulation influences the adoption of new technologies. Recognizing that the relationship between innovation and regulation is complex, we develop the concept of regulation as multifaceted and examine three interrelated aspects of regulation: (1) regulatory requirements, (2) regulators and …

Associations Of Neighborhood Socioeconomic Conditions With Self-Rated Health, Mental Distress, And Health Behaviors: A Nationwide Cross-Sectional Study In Japan, Tomoya Hanibuchi, Tomoki Nakaya

Geography Faculty Publications and Presentations

Although associations between neighborhood socioeconomic conditions and health have been well established, their geographical scope is mostly limited to Western societies, while multilevel studies in the non-Western context (e.g., Japan) are limited to specific cities/regions within countries. This consequently limits the external validity of the findings. To fill the gap, this study examined the associations between neighborhood socioeconomic conditions and health-related indicators by using nationwide cross-sectional data in Japan. Individual data was collected from a nationwide online survey conducted in 2015 (n = 4593). Self-rated health, mental distress (Kessler Psychological Distress Scale: K6), smoking, and physical activity were analyzed in …

A Digital Archive Of Human Activity In The Mcmurdo Dry Valleys, Antarctica, Adrian Howkins, Stephen M. Chignell, Poppie Gullett, Andrew G. Fountain, Melissa Carrie Brett, Evelin Preciado

Geography Faculty Publications and Presentations

Over the last half century, the McMurdo Dry Valleys (MDV) of East Antarctica have become a globally important site for scientific research and environmental monitoring. Historical data can make important contributions to current research activities and environmental management in Antarctica but tend to be widely scattered and difficult to access. We address this need in the MDV by compiling over 5000 historical photographs, sketches, maps, oral interviews, publications, and other archival resources into an online digital archive. The data have been digitized and georeferenced using a standardized metadata structure, which enables intuitive searches and data discovery via an online interface. …

Evaluating Cmip6 Model Fidelity At Simulating Non-Gaussian Temperature Distribution Tails, Arielle J. Catalano, Paul Loikith, J. David Neelin

Geography Faculty Publications and Presentations

Under global warming, changes in extreme temperatures will manifest in more complex ways in locations where temperature distribution tails deviate from Gaussian. Confidence in global climate model (GCM) projections of temperature extremes and associated impacts therefore relies on the realism of simulated temperature distribution tail behavior under current climate conditions. This study evaluates the ability of the latest state-of-the-art ensemble of GCMs from the Coupled Model Intercomparison Project phase six (CMIP6), to capture historical global surface temperature distribution tail shape in hemispheric winter and summer seasons. Comparisons with a global reanalysis product reveal strong agreement on coherent spatial patterns of …

Socio-Hydrology: An Interplay Of Design And Self-Organization In A Multilevel World, David J. Yu, Heejun Chang, Taylor T. Davis, Vicken Hillis, Landon T. Marston, Woi Sok Oh, Murugesu Sivapalan, Timothy M. Waring

Geography Faculty Publications and Presentations

The emerging field of socio-hydrology is a special case of social-ecological systems research that focuses on coupled human-water systems, exploring how the hydrologic cycle and human cultural traits coevolve and how such coevolutions lead to phenomena of relevance to water security and sustainability. As such, most problems tackled by socio-hydrology involve some aspects of engineering design, such as large-scale water infrastructure, and self-organization in a broad context, such as cultural change at the population level and the hydrologic shift at the river basin or aquifer level. However, within the field of socio-hydrology, it has been difficult to find general theories …

Central Tokyo’S Low Response Rate To The 2015 Population Census And Its Related Factors, Tomoya Hanibuchi, Masakazu Yamauchi

Geography Faculty Publications and Presentations

Recently, there has been an increase in the number of “unreported” cases in the Population Census of Japan caused by nonresponses to the survey. Subsequently, this has led to data reliability challenges. In light of this problem, the factors related to the low response rate of the 2015 Population Census in the central Tokyo area are examined in the present study. An online survey was conducted among individuals residing in the three Special Wards of Tokyo to inquire about their responses (submitted or not submitted) to the previous census. The statistical analyses demonstrated that particularly in central Tokyo, middle-aged (35–49 …

Crossing Boundaries: Steps Toward Measuring Undergraduates' Interdisciplinary Science Understanding, Brie Tripp, Sophia A. Voronoff, Erin Shortlidge

Biology Faculty Publications and Presentations

A desired outcome of education reform efforts is for undergraduates to effectively integrate knowledge across disciplines in order to evaluate and address real-world issues. Yet there are few assessments designed to measure if and how students think interdisciplinarily. Here, a sample of science faculty were surveyed to understand how they currently assess students’ interdisciplinary science understanding. Results indicate that individual writing-intensive activities are the most frequently used assessment type (69%). To understand how writing assignments can accurately assess students’ ability to think interdisciplinarily, we used a preexisting rubric, designed to measure social science students’ interdisciplinary understanding, to assess writing assignments …

From Trulia To Akorn: A Ride On The Roller Coaster Of M&A Litigation, Pierluigi Matera, Ferruccio M. Sbarbaro

Faculty Scholarship

In recent years, M&A litigation has experienced a dramatic increase, culminating with a peak in 2015, when over 96. of publicly announced mergers were challenged in a shareholder lawsuit. A large number of these lawsuits were frivolous and vexatious, since most claims were filed by plaintiffs' attorneys just to extract some fees with little effort. Some abusive practices emerged, signalling an alarming exploitation of the system. One scheme that plaintiffs' attorneys put in place was the disclosure-only settlement. There, the stockholders obtained some modest supplemental disclosures, the plaintiff's attorneys got significant fee awards from the defendant directors and the defendant …

Walking Dena’Ina: A Cultural Landscape Report For The Telaquana Trail, Douglas Deur, Jamie Hebert, John Branson, Tricia Brown

Anthropology Faculty Publications and Presentations

The Telaquana Trail is an ancient pathway ascending from the shores of Qizhjeh Vena, Lake Clark, through tundra and timbered valleys, into a high-elevation expanse of rolling tundra and smaller interior lakes nearly 50 miles north of Lake Clark. The pathway is an ancestral corridor used by Native peoples since the beginning of remembered time. Though the archaeological record of the trail is still coming into focus, it lends us important clues about the trail and how it was used. For example, archaeological evidence at places like Twin Lakes and Snipe Lake suggests that ancestral Native communities occupied and traveled …

Environmental Law, Jocelyn Stacey

All Faculty Publications

In commemoration of their 50th anniversary, this chapter examines the Federal Courts’ role in shaping environmental law in Canada. The chapter uses well-known environmental principles – the precautionary principle, sustainable development and access to (environmental) justice – as focal points for examining environmental law as well as the legal culture of the Federal Courts. The chapter identifies four distinct interpretive roles that the Federal Courts have ascribed to the precautionary principle and it argues that three of these roles have the potential to generate more coherent and transparent doctrine that upholds the rule of law in the environmental context. In …

Stretching The Dollar: Exploring The Lived Experiences, Multiple Identities, And Class Politics Of Poor And Working-Class Women At The University Of Kentucky, Rachael Deel

Theses and Dissertations--Education Sciences

In the climate of prioritizing retention and pressure to move an increasingly diverse undergraduate population towards degree, it is critical that educational research consider the multiple, overlapping identities of students and how that influences their experiences on campus. The number of low-income students entering four-year institutions is growing each year, including at the University of Kentucky. This study aims to extend our understanding of social class beyond the material and focus on the affective dimensions of class including language, comportment, and leisure activities in an effort to better understand how poor and working-class women contend with the constraints they encounter …

Can Less Be More? Study Load And Its Effect On Science Achievement Among Chinese Eighth-Grade Students, Xian Wu

Theses and Dissertations--Education Sciences

The present study addressed a core research question of “Can less be more?” concerning study load, which has become increasingly worrisome and controversial around the world. This idea reflects the philosophy of pursuing efficiency and effectiveness on learning, namely that a lighter study load may result in more successful academic achievement. The study adopted the IPO (input-process-output) model to address five interrelated research questions: 1) What are the structural characteristics of study load? 2) Is there any individual difference in study load? 3) What are the characteristics of teachers and schools under which students tend to have a heavier study …
