Increasing vegetable intake and diversity are recommended to maintain better health. Evidence for the health benefits of vegetable diversity, separate from total intake, is scarce. We aimed to investigate the associations of vegetable diversity with subclinical measures of atherosclerosis and atherosclerotic vascular disease (ASVD) mortality.

Making It Personal: Developing Sustainability Leaders In Business, Aoife Brophy Haney, Jenny Pope, Zoe Arden

Research outputs 2014 to 2021

Sustainability challenges present organizations in many industries with the need to change. Leaders are critical to the process of becoming more sustainable, and yet leading change for sustainability requires new competencies. Learning at an individual level is central to developing new competencies; however, there has been limited focus to date in the literature on corporate sustainability on how leaders can learn to respond to sustainability challenges. In this article, we focus on how managers learn to become sustainability leaders in their organizations by exploring the phenomenon of experiential learning programmes. We do this by interviewing participants and organizers of four …

Countering Deficit Thinking About Neurodiversity Among General Education Teacher Candidates: A Case Discussion Approach, Grinell Smith, Colette Rabin

Faculty Research, Scholarly, and Creative Activity

We have observed that many of the multiple-subjects teacher credential candidates in our program often reveal deficit views of autistic children. This report provides an example of how we help credential candidates learn to reframe deficit thinking about neurodiversity via the examination, discussion, and dramatization of a collection of dilemma-based case stories designed to help our students unearth preconceptions and engage in shared inquiry. One strength of this approach is that it asks candidates to develop specific and realistic plans of action, to adopt a care ethic requiring them to think and act from the perspective of the child, to …

A Sense Of Brutality: Philosophy After Narco-Culture, Carlos Alberto Sánchez

Faculty Research, Scholarly, and Creative Activity

Contemporary popular culture is riddled with references to Mexican drug cartels, narcos, and drug trafficking. In the United States, documentary filmmakers, journalists, academics, and politicians have taken note of the increasing threats to our security coming from a subculture that appears to feed on murder and brutality while being fed by a romanticism about power and capital. Carlos Alberto Sánchez uses Mexican narco-culture as a point of departure for thinking about the nature and limits of violence, culture, and personhood. A Sense of Brutality argues that violent cultural modalities, of which narco-culture is but one, call into question our understanding …

Mathematical Modelling For Multiproduct Epq Problem Featuring Delayed Differentiation, Expedited Rate, And Scrap, Singa Wang Chiu, Jia Ning Lin, Yunsen Wang, Hong Dar Lin

Department of Accounting and Finance Faculty Scholarship and Creative Works

The client requirements of present-day markets emphasize product quality, variety, and rapid response. To gain competitive advantages in marketplaces and meet customer needs, manufacturers today seek the most economical and fastest fabrication schemes and strategies to produce their various goods, especially when commonality exists within these multiple end products. Inspired by the above viewpoints, this study uses a mathematical modelling approach for solving a multiproduct economic production quantity (EPQ) problem featuring scrap, delayed differentiation, and expedited rate on the fabrication of the common part. We build a two-stage multiproduct fabrication scheme. Stage one uses an accelerated rate to produce all …

Presently, there are a few cases that address the Foreign Corrupt Practices Act and its effect on financial reporting and auditor responsibilities about illegal acts. The Armor Holdings case is interesting and information is …

Ethereum As A Hedge: The Intraday Analysis, A. Meshcheryakov, Stoyu Ivanov

Faculty Research, Scholarly, and Creative Activity

In this study, we examine on intraday basis Ether-the token or cryptocurrency based on the Ethereum platform. Ether is the second largest crypto-currency, together with Bitcoin they dominate the cryptocurrency universe and account for almost 70% of combined market share. Similar to Bitcoin, Ethereum experienced rapid growth in price from a few cents per Ether after its introduction in 2015 reaching maximum of $1,432.88 on January 13, 2018. In this paper, we study whether Ethereum crypto-currency is a hedge, diversifier or a safe haven asset. We find that Ethereum crypto-currency is a hedge against the US stock and gold markets. …

The Right Family, Noa Ben-Asher, Margot J. Pollans

Elisabeth Haub School of Law Faculty Publications

The family plays a starring role in American law. Families, the law tells us, are special. They merit, among others, tax deductions, testimonial privileges, untaxed inheritance, parental presumptions, and, over the course of the twentieth century, the Supreme Court has expanded individual rights stemming from familial relationships. In this Article, we argue that family matters as much for when it is ignored as for when it is featured. We shed light on the use of the family in the law by contrasting policies in which the family is the key unit of analysis with others in which it is not. …

Teaching With Feminist Judgments: A Global Conversation, Bridget J. Crawford, Kathryn M. Stanchi, Linda L. Berger, Gabrielle Appleby, Susan Frelich Appleton, Ross Astoria, Sharon Cowan, Rosalind Dixon, J. Troy Lavers, Andrea L. Mcardle, Elisabeth Mcdonald, Teri A. Mcmurtry-Chubb, Vanessa E. Munro, Pamela A. Wilkins

Elisabeth Haub School of Law Faculty Publications

This conversational-style essay is an exchange among fourteen professors—representing thirteen universities across five countries—with experience teaching with feminist judgments. Feminist judgments are ‘shadow’ court decisions rewritten from a feminist perspective, using only the precedent in effect and the facts known at the time of the original decision. Scholars in Canada, England, the U.S., Australia, New Zealand, Scotland, Ireland, India, and Mexico have published (or are currently producing) written collections of feminist judgments that demonstrate how feminist perspectives could have changed the legal reasoning or outcome (or both) in important legal cases. This essay begins to explore the vast pedagogical potential …

The 2018 Camp Fire: Meteorological Analysis Using In Situ Observations And Numerical Simulations, Matthew J. Brewer, Craig B. Clements

Faculty Research, Scholarly, and Creative Activity

The November 2018 Camp Fire quickly became the deadliest and most destructive wildfire in California history. In this case study, we investigate the contribution of meteorological conditions and, in particular, a downslope windstorm that occurred during the 2018 Camp Fire. Dry seasonal conditions prior to ignition led to 100-h fuel moisture contents in the region to reach record low levels. Meteorological observations were primarily made from a number of remote automatic weather stations and a mobile scanning Doppler lidar deployed to the fire on 8 November 2018. Additionally, gridded operational forecast models and high-resolution meteorological simulations were synthesized in the …

An Ultra-Low-Power Area-Efficient Non-Coherent Binary Phase-Shift Keying Demodulator For Implantable Biomedical Microsystems, Milad Ghazi, Mohammad Hossein Maghami, Parviz Amiri, Sotoudeh Hamedi-Hagh

Faculty Research, Scholarly, and Creative Activity

A novel non-coherent, low-power, area-efficient binary phase-shift keying demodulator for wireless implantable biomedical microsystems is proposed. The received data and synchronized clock signal are detected using a delayed digitized format of the input signal. The proposed technique does not require any kind of oscillator circuit, and due to the synchronization of all circuit signals, the proposed demodulator can work in a wide range of biomedical data telemetry common frequencies in different process/temperature corners. The presented circuit has been designed and post-layout-simulated in a standard 0.18 µm CMOS technology and occupies 17 × 27 µm2 of active area. Post-layout simulation results …

Determination Of Demagnetizing Factors Using First-Order Reversal Curves And Ferromagnetic Resonance, K. S. Muster, R. Heindl

Faculty Research, Scholarly, and Creative Activity

We present a method to quantitatively analyze magnetizing or demagnetizing interactions in arrayed nano-magnets by combining first-order reversal curve (FORC) and ferromagnetic resonance (FMR) measurement data. We develop a function to predict the resulting FORC distribution given: (1) a Gaussian intrinsic distribution in terms of the internal field and (2) a mean interaction field proportional to the sample's magnetic moment. We then perform least-squares regression of our model on experimental FORC measurements of a nanowire array and of a thin film. Combining the obtained interaction field with an FMR fit result allows us to algebraically solve for the effective axial …

The Relationship Between Workload, Performance And Fatigue In A Short-Haul Airline, Lucia Arsintescu, Ravi Chachad, Kevin B. Gregory, Jeffrey B. Mulligan, Erin E. Flynn-Evans

Faculty Research, Scholarly, and Creative Activity

The aim of this study was to determine the relationship between pilot workload, performance, subjective fatigue, sleep duration, number of sectors and flight duration during short-haul operations. Ninety pilots completed a NASA Task Load Index, Psychomotor Vigilance Task and a Samn-Perelli fatigue scale on top-of-descent of each flight and wore an activity monitor throughout the study. Weak, but significant, correlations were revealed between workload and all factors. Subjective fatigue, number of sectors and lapses were significant predictors of workload. Pilots reported higher workload when fatigue increased, the number of sectors were higher, and objective performance was worse.

Mitigating Fatigue On The Flight Deck: How Is Controlled Rest Used In Practice?, Cassie J. Hilditch, Lucia Arsintescu, Kevin B. Gregory, Erin E. Flynn-Evans

Faculty Research, Scholarly, and Creative Activity

Controlled Rest (CR) refers to a short, unscheduled, voluntary nap opportunity taken by pilots on the flight deck as a countermeasure to unanticipated fatigue in flight. This study explores the profile of CR use in a long-haul commercial airline. Forty-four pilots wore actiwatches and filled in an application-based sleep/work diary for approximately 2 weeks resulting in complete records from 239 flights. Timing of sleep periods and flight schedules were analyzed relative to home-base time. Pearson correlations were used to assess the influence of pilot demographics on CR use. A mixed-effects logistic regression was used to analyze the impact of schedule …

Students’ Exploring And Refining Their Equity Ethic Within The Access Network, Fidel Amezcua, Gina M. Quan, Chandra A. Turpen

Faculty Research, Scholarly, and Creative Activity

The Access Network is an organization that supports vibrant interactions among students and faculty who advocate for equity work in the physical sciences. This paper uses McGee and Bentley’s framework of “equity ethic” (EE) to understand how Access student leaders adopt and refine a commitment to equity and social justice work within the physical sciences. In McGee and Bentley’s study of STEM students of color, they define EE as students’ sense of altruism and collectivism within and outside of their communities. Through interviews with student leaders, we model components of students’ EEs and how their EEs are influenced by their …

Sandy Beaches Can Survive Sea-Level Rise, J. A.G. Cooper, G. Masselink, G. Coco, A. D. Short, B. Castelle, K. Rogers, E. Anthony, A. N. Green, J. T. Kelley, O. H. Pilkey, D. W.T. Jackson

School of Biological and Marine Sciences

Vousdoukas et al. assert that global sea-level rise (SLR) poses a threat to the existence of sandy beaches. They use global databases of sandy beaches, bathymetry and wave conditions to drive a simple model based on the Bruun rule to quantify shoreline retreat, to which they add a background ambient trend based on satellite data. When retreat is more than 100 m by 2100, they declare those beaches near extinct by the end of the century. We feel that this is an incorrect and potentially damaging finding. Critical to the paper’s conclusions is the fact that, provided that accommodation space …

Analysis Of Direct And Indirect Genetic Effects In Fighting Sea Anemones, Sarah M. Lane, Alastair J. Wilson, Mark Briffa

School of Biological and Marine Sciences

Abstract Theoretical models of animal contests such as the Hawk-Dove game predict that variation in fighting behavior will persist due to mixed evolutionarily stable strategies (ESS) under certain conditions. However, the genetic basis for this variation is poorly understood and a mixed ESS for fighting can be interpreted in more than one way. Specifically, we do not know whether variation in aggression within a population arises from among-individual differences in fixed strategy (determined by an individual’s genotype—direct genetic effects [DGEs]), or from within-individual variation in strategy across contests. Furthermore, as suggested by developments of the original Hawk-Dove model, within-individual variation …

Chytrid Fungi Shape Bacterial Communities On Model Particulate Organic Matter, Cordelia Roberts, Ro Allen, Kimberley E. Bird, Michael Cunliffe

School of Biological and Marine Sciences

Microbial colonization and degradation of particulate organic matter (POM) are important processes that influence the structure and function of aquatic ecosystems. Although POM is readily used by aquatic fungi and bacteria, there is a limited understanding of POM-associated interactions between these taxa, particularly for early-diverging fungal lineages. Using a model ecological system with the chitin-degrading freshwater chytrid fungus Rhizoclosmatium globosum and chitin microbeads, we assessed the impacts of chytrid fungi on POM-associated bacteria. We show that the presence of chytrids on POM alters concomitant bacterial community diversity and structure, including differing responses between chytrid life stages. We propose that chytrids …

Both Maternal And Embryonic Exposure To Mild Hypoxia Influence Embryonic Development Of The Intertidal Gastropod Littorina Littorea (Linnaeus, 1758)., James C.S. Mccoy, John I. Spicer, Oliver Tills, Simon D. Rundle

School of Biological and Marine Sciences

There is growing evidence that maternal exposure to environmental stressors can alter offspring phenotype and increase fitness. Here, we investigate the relative and combined effects of maternal and developmental exposure to mild hypoxia (65% and 74% air saturation respectively) on the growth and development of embryos of the marine gastropod Littorina littorea. Differences in embryo morphological traits were driven by the developmental environment, whereas the maternal environment and interactive effects of maternal and developmental environment were the main driver of differences in the timing of developmental events. While developmental exposure to mild hypoxia significantly increased the area of an important …

Challenges Of Diagnosis And Management Of Postpartum Choriocarcinoma In Resource Limited Settings: A Case Report From A Tertiary Hospital Of Western Kenya, Amubuomombe Philippe, Benjamin Elly, Andrew Cheruiyot, Sahara Shurie, Elkanah Omenge

Obstetrics and Gynaecology, East Africa

Choriocarcinoma is a rare occurrence in pregnancy. It is a highly curable malignant tumour that arises from trophoblastic cells within the uterus. However, the timely diagnosis of choriocarcinoma following birth is challenging, especially in low resource settings because most clinicians are not aware about the existence of the disease following uneventful pregnancy and birth. This report discusses the case of a 28 years old patient, para 2, diagnosed with choriocarcinoma two months after uneventful vaginal delivery at term. She underwent a total abdominal hysterectomy, followed by chemotherapy treatment; and succumbed to her disease. It highlights difficulties encountered on diagnosis and …
