Meal-time Smartphone Use in an Obesogenic Environment: Two Longitudinal Observational Studies
Authors: Yong Joceline Y Y , Tong Eddie M W , Liu Jean C J
Published: April 2021

Background

Despite a large volume of research on the impact of other digital screens (eg, televisions) on eating behavior, little is known about the nature and impact of mealtime smartphone use.

Objective

We investigated how smartphones are used in everyday meals, whether phone users differ according to mealtime phone use patterns, and whether specific phone functions (particularly food photography) would affect the amount and enjoyment of food eaten.

Methods

Across 2 studies, we used the experience sampling method to track 1780 meals in situ. In study 1, a total 137 young adults reported on their mealtime smartphone use 3 times per day over 7 consecutive days. This corresponded to each main meal, with participants recording whether they used their phones and what phone functions they engaged in while eating. In study 2, a total of 71 young adults were similarly tracked for 3 meals per day over 7 days. Across the week, participants’ meals were randomized to 1 of 3 smartphone conditions: food photography while eating, nonfood photography while eating, or no phone use. As the outcome measures, participants reported on the amount and enjoyment of food they ate.

Results

During the week-long tracking, most participants (110/129, 85.3%) recorded at least one instance of mealtime smartphone use, with an average frequency of 1 in 3 meals where phones were used (27.1%; 95% CI 23.6-30.6). Unlike traditional digital screens, mealtime phone use encompassed a wide range of social and nonsocial activities. Further, specific forms of phone use behaviors influenced food intake in different ways. Specifically, in study 2, participants showed the typical pattern of increased food intake across the day when they engaged in nonfood photography during a meal (P<.001); however, this pattern was disrupted when they engaged in food photography (P=.73).

Conclusions

Our findings underscore the prevalence and multifaceted nature of mealtime phone use, distinguishing mobile phones from traditional forms of digital screens.

Impact of an Online Gastrointestinal Symptom History Taker on Physician Documentation and Charting Time: Pragmatic Controlled Trial
Authors: Hall Natalie J , Berry Sameer K , Aguilar Jack , Brier Elizabeth , Shah Parth , Cheng Derek , Herman Jeremy , Stein Theodore , Spiegel Brennan M R , Almario Christopher V
Published: April 2021

Background

A potential benefit of electronic health records (EHRs) is that they could potentially save clinician time and improve documentation by auto-generating the history of present illness (HPI) in partnership with patients prior to the clinic visit. We developed an online patient portal called AEGIS (Automated Evaluation of Gastrointestinal [GI] Symptoms) that systematically collects patient GI symptom information and then transforms the data into a narrative HPI that is available for physicians to review in the EHR prior to seeing the patient.

Objective

This study aimed to compare whether use of an online GI symptom history taker called AEGIS improves physician-centric outcomes vs usual care.

Methods

We conducted a pragmatic controlled trial among adults aged ≥18 years scheduled for a new patient visit at 4 GI clinics at an academic medical center. Patients who completed AEGIS were matched with controls in the intervention period who did not complete AEGIS as well as controls who underwent usual care in the pre-intervention period. Of note, the pre-intervention control group was formed as it was not subject to contamination bias, unlike for post-intervention controls. We then compared the following outcomes among groups: (1) documentation of alarm symptoms, (2) documentation of family history of GI malignancy, (3) number of follow-up visits in a 6-month period, (4) number of tests ordered in a 6-month period, and (5) charting time (difference between appointment time and time the encounter was closed). Multivariable regression models were used to adjust for potential confounding.

Results

Of the 774 patients who were invited to complete AEGIS, 116 (15.0%) finished it prior to their visit. The 116 AEGIS patients were then matched with 343 and 102 controls in the pre- and post-intervention periods, respectively. There were no statistically significant differences among the groups for documentation of alarm symptoms and GI cancer family history, number of follow-up visits and ordered tests, or charting time (all P>.05).

Conclusions

Use of a validated online HPI-generation portal did not improve physician documentation or reduce workload. Given universal adoption of EHRs, further research examining how to optimally leverage patient portals for improving outcomes are needed.
Disruptive Changing Higher Education Ecosystems: Have University Academics Been Gazumped?
Authors: Long Dr Warrick , Barnes Associate Professor Lisa , Northcote Professor Maria , Williams Professor Anthony
Published: April 2021

Continual reforms in the Australian Higher Education Sector result in ongoing significant changes to the experiences of the Australian academic. As a result, massification, internationalisation and corporatization form the landscape of academia in Australia. The Australian University Accounting Academic (AUAA) faces ongoing challenges and opportunities within this dynamic academic environment, and this study explores these challenges in relation to teaching themed issues that confront the AUAA. By using a questionnaire and interviews with AUAAs, three themes emerged, being curriculum, teaching workload, and the impact of online teaching. The “ASSET” support framework is developed from these conversations with the AUAA’s to help them become an “asset” to the university during these times of disruptive change instead of allowing the system to “gazump” them.
Application of Flipped Classroom Methodology in Applied Sciences through STEM Exploitation Activities during COVID Pandemic Period

Published: April 2021

Differentiated instruction is an approach that presupposes the existence of a diverse number of students and their ability to access knowledge provided that a variety of methods and activities is used. Differentiated instruction is a way to incorporate and diagnose the individual needs of every student separately and to create such a learning environment so as to cover all needs. All students are not the same that means that they learn in different ways and at a different pace. Based on this knowledge, differentiated instruction applies an approach both to teaching and learning that offers the students a variety of choices to gain information and better understand the newly acquainted knowledge. Differentiated instruction is a teaching approach based on the principle that all teaching techniques must vary and adapt accordingly in relation to the needs and the various ways of learning on the part of the students with the view of enhancing the understanding of knowledge within the classroom. The model of differentiated instruction proposed requires on the part of the teachers to be flexible in the technique they use and adaptable in the curriculum and in the presentation of the information based on the needs of the students. Based on the idea that change in teaching practices may help overcome the ineffectiveness of the educational systems and their inability to cover the needs of the students, it is considered necessary to examine whether the use of differentiated instruction learning approach could improve the understanding of the students in the fields of applied sciences.

Dynamic thiol-disulfide balance and thioredoxin reductase enzyme levels in patients with chronic kidney disease.
Authors: Erdal Huseyin , Ozcan Oguzhan , Turgut Faruk , Neselioglu Salim , Erel Ozcan
Published: April 2021

Introduction: We aimed to measure the dynamic thiol-disulfide balance
and thioredoxin reductase (TrxR) enzyme levels in patients with chronic
kidney disease (CKD). Material and Methods: Thirty hemodialysis (HD), 30
CKD patients (stage3-5) and 30 controls were included in the study. The
dynamic thiol-disulfide balance was determined by the colorimetric
method developed by Erel et al. TrxR levels were determined by ELISA.
Results: Native and total thiol levels of CKD and HD patients were
significantly lower than that of the control group (p=0.001for both).
However, disulfide levels were significantly higher in the HD group
(p=0.001), but there was no significant difference between control and
CKD groups(p=0.547). A notable negative correlation was found between
the native and total thiol levels and IMA(r=-0.628;-0.631),BUN
(r=-0.747;-0.747),and creatinine(r=-0.732;-0.721). There was a
significant positive correlation between GFR and the thiol levels
(r=0.835;0.824). TrxR levels were significantly higher in the patient
groups compared to the controls (p=0.001).CRP levels of the patient
groups were significantly higher compared to the controls (p=0.001).
Conclusions: We have demonstrated that measurement of dynamic
thiol-disulfide levels by using colorimetric method can contribute to
the diagnosis and follow-up of the disease as a marker, because, it is
easily applicable in routine clinical biochemistry laboratories and
related with disease severity in CKD patients. Also, we showed that
volume correction due to dialysis process should be consider in studies
dealing with plasma thiol values and the final results should be given
after the correction process.
The early bird uses bioRxiv: The impact of career stage on the usage of preprints in ecology and evolution
Authors: Wolf Jesse , MacKay Layla , Haworth Sarah , Cossette Marie-Laurence , Dedato Morgan , Young Kiana , Elliott Colin , Oomen Rebekah
Published: April 2021

The usage of preprint servers in ecology and evolution is increasing, as
it allows for research to be rapidly disseminated and available through
open access at no cost. This is relevant for Early Career Researchers
(ECRs), who must demonstrate research ability for funding opportunities,
scholarships, grants, or faculty positions in short temporal windows in
order to advance their careers. Concurrently, limited experience with
the peer review process can make it challenging for those who are in the
early stages of their research career to build publication records.
Therefore, ECRs face different challenges relative to researchers with
permanent positions and established research programs and have different
requirements in terms of research output and timelines. These challenges
might also vary according to institution size and country, which are
associated with the availability of funding for open access journals.
Herein, we hypothesize that career stage and institution size impact
relative usage of preprint servers among researchers in ecology and
evolution. Using data collected from 500 articles (100 from each of two
open access journals, two closed access journals, and a preprint
server), we demonstrate that ECRs generate more preprints relative to
non-ECRs, for both first and last authors. We speculate that this
pattern is reflective of the advantages of quick and open access
research that is disproportionately beneficial to ECRs. There is also a
marginal effect of first author institution size on preprint usage,
whereby the number of preprints tends to increase with institution size
for ECRs, although the interaction between ECR status and institution
size was not significant. The United States and United Kingdom
contributed the greatest number of preprints by early career
researchers, whereas non-western countries contributed relatively fewer
preprints. This research provides empirical evidence regarding
motivations of preprint usage and barriers surrounding large-scale
adoption of preprinting in ecology and evolution.

Published: April 2021

With the rapid increasing bandwidth demand mainly driven by the development of advanced broadband multimedia application, such as video-on-demand (VoD), interactive high-definition digital television (HDTV) and video conference, new access network solutions that provide high capacity are highly needed to satisfy these emerging services. In a largely populated and technologically exposed institution such the University of Port Harcourt, this demand is truly great. The Passive Optical Network (PON), which utilizes the Fibre Optic Technology, is a suitable solution to this problem. Hence this is geared towards the design and simulation of a Passive Optical Network for the University’s campus district. This Campus based Local Area Network consists of the Various Faculty buildings, the Senate building which is the central administrative building, and was centralized at the Information and Communication Technology Center (ICTC), which served as the Central Office of the network. The Wavelength Division Multiplexing (WDM) technique was utilized because of its dedicated bandwidth for each subscriber and more flexible bandwidth management. The validation was carried out on a virtual computation environment called OptiSystem©.

Published: April 2021

This research aims to determine the effectiveness of the heat and temperature module based on the Guided-Inquiry Laboratory (GIL) model. The type of this research was a quasi-experimental research with a pretest-posttest control group design.  The samples were the seventh grade of one of junior high school in Kediri, as many as 60 students, with two classes: module as experiment class and existing class as control class. The module class was treated using a GIL-based module and existing class using modules commonly used at school. The sampling technique used in this research was purposive sampling. The instrument used to collect data on scientific inquiry literacy was a multiple-choice test. This study found that there are statistically significant differences between the module and the existing class with an Effect Size (ES) of 0,413. The average score of scientific inquiry literacy N-Gains score calculation in the module class was higher by 0,68 compared to the existing class 0f 0,47. The result indicates that there is a medium impact of applying heat and temperature module to the indicator of scientific inquiry literacy. These findings contribute that employing the GIL-based heat and temperature module proved to be effective in the quality of science learning among module class students.
Quality improvement in teaching and learning science in primary school settings: Using a metaphor to approach the concept of light
Authors: Rodriguez James , Castro David
Published: April 2021

The present study focuses on the approach of the concept of light by primary school students. The study explores how a teaching procedure founded on using the metaphor that light travels as a wave reflects on the concept of light as a distinct natural entity. The experimental method was used for the research. One hundred and fifty-two children aged between 7 to 8 years old (average age 7.59) from 9 different primary school classes in Colorado, USA, participated in the research. An experimental and control group was delineated. Following a socio-cognitive perspective, the experimental group took part in a teaching procedure based on using the metaphor that light travels as a wave. Following an empiricist perspective, the control group took part in a teaching procedure based on a description of the phenomenon without using a metaphor. Data had been collected through pre and post-test, which results were analyzed using the Mann-Whitney test. The quantitative analysis showed an essential difference between the two groups. The experimental group pupils achieve higher learning outcomes as they better understand light as a distinct entity. It is argued that using a metaphor allows children to make connections with their everyday life, wonder about, and conceptualize light in a more efficient and meaningful way. The study informs everyday educational practice by providing a quality improvement element for learning and teaching about the primary classroom light

Indigenous knowledge can develop ways of thinking, creativity, and dynamics of indigenous peoples in an area. This study aimed to know the effectiveness of Physics Subject-specific Pedagogy (SSP) based on indigenous knowledge to improve students' patriotic character. This study focused on SSP product implementation through an experimental method, i.e., one group pretest-posttest design. The Physics SSP adopted the 4D research by Thiagarajan. This product consisted of a syllabus, lesson plans, worksheets, questionnaires, and observation sheets. This research was conducted at Senior High School 1 Turen, Malang, with two different treatments on sixty-six eleventh-grade students in the academic year of 2019/2020. The analyses performed were descriptive and analytical test analysis. Based on the homogeneity and normality test results, all pretest and posttest scores in both classes had homogeneous data. However, the data were not normally distributed. Based on the regression coefficient and the effect size value, the Physics SSP, based on indigenous knowledge, obtained an effect size value of 14.12%. However, the obtained value indicated that the effect of Physics SSP was in a low category.

Varieties of Theism and Explanations of Moral Realism
Authors: Jeffrey Anne
Published: April 2021

Does theism make a difference to whether there are moral facts? In this paper I suggest that, despite how much uptake this question gets in philosophical literature, it is not well formed. “Theism” leaves too indeterminate what God is like for us to discern what difference God’s existence would make to moral facts. Arguments like the explanans-driven argument for theistic moral realism and the explanationist argument for naturalist moral realism both require extra substantive assumptions about God in order to be valid and compelling. Specifically, the arguments must take a stand on whether God is personal or a-personal, and how this affects God’s relation to the natural world.
O ENSINO DA PSICANÁLISE NA GRADUAÇÃO EM PSICOLOGIA: PERCEPÇÃO DE PROFESSORES SOBRE A TRANSMISSÃO
Authors: Nogueira Cordeiro Sílvia , Dos Reis Maria Elizabeth Barreto Tavares , Sei Maíra Bonafe , Zanetti Sandra Aparecida Serra
Published: April 2021

Entende-se que o ensino e a transmissão da psicanálise implicam o diálogo entre dois aspectos: conhecimento acadêmico - objetivo e sistemático - e conhecimento produzido pela psicanálise - dinâmico e subjetivo. Objetivou-se, assim, discutir a percepção de docentes sobre o ensino e a transmissão da psicanálise na graduação em psicologia de uma universidade pública. Realizou-se um estudo qualitativo por meio de entrevistas semiestruturadas com docentes da área de psicanálise. Observou-se que, para os docentes, a universidade é um lócus de ensino e pesquisa em psicanálise, destacando-se a especificidade de seu modelo de transmissão, que considera o sujeito e seu desejo como inseparáveis do ato de ensinar e de pesquisar. Acredita-se, a despeito dos limites inerentes à transmissão da psicanálise no cenário universitário, que o ensino desta deve ser fomentado, despertando o interesse dos futuros psicólogos por este campo do saber.

PONTOS DE INFLEXÃO NA IDEIA DE GESTÃO EDUCACIONAL DE HELOÍSA LÜCK
Authors: Santana Zionel
Published: April 2021

O objetivo deste artigo é aproximar a delimitação conceitual em Heloíse Lück (2006) de gestão paradigmática a ideia de paradigma de Thomas Kuhn (2007). A delimitação conceitual de gestão paradigmática está presente na coleção de cadernos de Heloísa Lück (2006) em suas variações. Em Kuhn (2007), a ideia de paradigma foi desenvolvida em sua obra “A Estrutura das Revoluções Científicas”. Em um segundo momento aproximamos a delimitação conceitual de Lück (2006) sobre gestão da ideia de Follett (1997). O tipo de pesquisa utilizado na produção deste texto foi a bibliográfica de acordo com Köche (2015) que parte da apropriação de conceitos e concepções presentes na literatura.  Desta forma adotou-se o método hipotético-dedutivo (MARCONI; LAKATOS 2009) a partir do problema levantado sobre aproximação da ideia de gestão e da ideia de paradigma. O resultado da pesquisa aponta para o estranhamento entre a delimitação conceitual de gestão paradigmática em Kuhn (2007) e Follett (1997). A hipótese de trabalho nesta pesquisa parte da suposição que a delimitação da ideia de gestão de Lück (2006) traria possíveis interpretações diferentes sobre a gestão do ensino na educação brasileira.
Does habitual endurance exercise protect endothelial function against acute exposure to oscillatory shear stress?
Authors: Grewal A. S. , Tremblay J. C. , Preobrazenski N. , Gurd B. J.
Published: April 2021

Introduction: Acute exposure to increases in oscillatory shear stress (increased retrograde shear stress and decreased mean shear stress) reduces flow-mediated dilation (FMD). This impairment may be mediated via increased oxidative stress. Habitual endurance exercise training results in increased antioxidant protection. However, it is currently unknown whether these adaptations protect against oscillatory shear stress-induced impairments in FMD.

Purpose and Hypothesis: The purpose of this study is to determine whether lower limb endurance-trained athletes have protection against oscillatory shear stress-induced impairments in FMD compared to sedentary individuals. It is hypothesized that athletes will have a preserved FMD after an acute oscillatory shear stress intervention, compared to their sedentary counterparts.

Methods: Healthy, young adult volunteers (18-29 years old) will be screened for physical activity (PA) through a physical activity recall questionnaire. 12 sedentary individuals (<3h of structured PA/week) and 12 lower limb endurance athletes will be recruited to participate.  All participants will complete a VO2 peak test to objectively measure cardiorespiratory fitness. Participants will visit the laboratory twice in the same week for vascular testing. Both 90-minute visits will begin with 45 minutes of supine rest, followed by a brachial artery FMD test before and after 30 minutes of either imposed oscillatory shear stress (forearm cuff inflated to 70 mmHg) or a 30 min rest period (control). 

Significance: This will be the first study to investigate whether endurance-trained athletes are resistant to oscillatory shear-stress induced impairments in endothelial function. This will provide insight into mechanism contributing to the vasoprotective effects of habitual endurance exercise.
Access to essential medicines within the ethnic health system in eastern Myanmar
Authors: Boblitz Alexa
Published: April 2021

The eastern border region of Myanmar is a mainly rural area, with a large population of vulnerable groups due to internal displacement and ongoing ethnic conflict and discrimination. Myanmar has the 2nd lowest overall health system performance out of 191 countries internationally, and reports indicate that ethnic communities are largely excluded from formal healthcare. Health and human rights concerns have been raised over limited access to essential medicines (AEM)1,2. Implications of not having AEM, such as antibiotics and vitamins, include high rates of morbidity, suffering, and morality at individual levels and low average life expectancy and poor overall health at the population level3. This cross-sectional study aims to describe the current level of access to seven different essential children’s medicines in 98 clinics in eastern Myanmar, using stock data from the Health Facility Assessment Tools 2017 Survey. The association between level of clinic remoteness (distance to the clinic from a large city) and AEM is being explored. Data analysis is currently being conducted and results will be available in March 2019. There is limited research pertaining to this geographic region and population despite evidence of a damaged health system and a high volume of potentially vulnerable people. Therefore, the findings of this study could inform further investigations to improve equitable access to essential medicines among all people in eastern Myanmar.

Multiple Risk Behaviours and Concussions among Adolescents in Ontario
Authors: Shore Josh
Published: April 2021

Concussion has become a significant public health concern among Canadian youth, as estimates of pediatric concussion incidence have increased from 340.5 per 100,000 in 2003 to 601.3 in 2010, and 1500 in 2013. This recent surge in concussion diagnosis has led to extensive research into the physiological mechanisms underlying traumatic brain injury, as well as sport-focused policies and return to play protocols following concussion. However, there is a paucity of research regarding social and behavioural risk factors for the development of a concussion. Multiple risk behaviours (MRB) represent a clustering of behaviours that often develop together during adolescence, such as alcohol consumption, illicit drug use and unprotected sex. These behaviours indicate an increased tendency for risk-taking, and have previously been associated with an increased risk for injury. Although the current literature describes a consistent injury risk gradient associated with increasing engagement in MRB, few studies have examined the relationship between engagement in MRB and the incidence of specific injuries. This study further investigates pediatric concussion through two research objectives. The first objective is to describe concussion prevalence, differences in prevalence by age and sex, as well as activity leading to concussion, among Canadian youth in grades 6-10. The second objective is to investigate the relationship between engagement in multiple risk behaviours and concussion within the same population. It is hypothesized that children engaging in greater risky behaviour will exhibit higher concussion prevalence. The results of this study may be used to inform behavioural interventions designed to reduce concussion in youth.
The Political Representation of Women in the Soviet Union Compared to Modern-day Democratic Russia
Authors: Tyvodar Bohdan
Published: April 2021

Over 25 years after Russia’s independence, Russia has established itself as one of the world’s most powerful countries, however, it seems to have forgotten about its women.  This study examines why women in the Soviet Union were more represented in political institutions, specifically in the national government, than women in modern-day, democratic Russia.  This study is timely and relevant because women’s political representation is an issue to which a lot of attention is devoted in the media and in academic literature.  This study investigates and compares women’s involvement in political institutions in the Soviet era compared to the post-Soviet, democratic era, a natural turning point in which we would logically expect growth rather than retraction of women’s political representation.  Period one encompasses women’s representation in political institutions of the Soviet Union from 1922-1991, with an emphasis on the Gorbachev era.  Meanwhile, period two encompasses women’s representation in political institutions of modern-day Russia, 1991 to today.  The research in this study indicates that the Marxist-Leninist ideology of the Soviet Union, the political liberalization started by the Soviet Union in the late 1980s and continued by Russia in the early to mid 1990s, and the rise of conservatism in post-Soviet Russia, are three important factors accounting for the increased gender imbalance in representation in the modern era.
Comprehension

The purpose of our collaborative research is to explore what it takes for an educator to bring about genuine comprehension of any subject matter and to measure the level of comprehension attained by students. Student comprehension has been defined as the ability to perform sets of sub-skills to a level of mastery (McTighe, 2018). Comprehension is evident when students demonstrate applications of their knowledge to new situations, explain their thinking, and justify their conclusions (Brookheart, 2010). Findings suggest that there are five main pillars supporting student comprehension; a) Identifying, b) Connecting, c) Questioning, d) Reiterating, and e) Communicating. Each component involves action by both instructor and learner to promote absorption of information. To assess whether these steps are effective, educators must implement different testing constructs. “Levels of mastery” is an assessment scale that focuses on comprehension. Teachers can also prompt students to provide evidence supporting their observations. This multifaceted understanding of comprehension is essential for new teacher candidates so that they can provide the most effective instruction for the learning process and lead to fuller intellect amongst our students and beyond. Further research on this topic could establish the effects of implementing these methods and explore the changes required to enact the five pillars within the current curriculum context.
Engaging with Indigenous Research
Authors: Franks Olivia
Published: April 2021

Community-based participatory research (CBPR) within Indigenous communities aims to share project responsibilities and benefits equitably among community members and researchers. CBPR relies on authentic relationships that take time to build; so how does a student from a colonial institution such as Queen’s University build the necessary relationships? As a Kanien'kehá:ka (Mohawk) student about to begin my graduate degree focusing on health promotion through a CBPR partnership with Indigenous communities, I will share my story and background of disconnect, as well as the identity-struggles I had prior to deciding that this field of research was right for me. Through this presentation, I will discuss the upfront process of being involved with Indigenous research as an Indigenous student, an advocate, and an ally. Regardless of Indigenous status, examining the research process in the context of individual positionality and researcher self-awareness is critical to successful CBPR research.  My goal is to provide both Indigenous and non-Indigenous research trainees with important insight about positionality, identity, power, and relationship-building as vital components of community-engaged research. I will discuss how the principles of CBPR align with Indigenous ideals and how these can be leveraged to establish connections that can support meaningful research with Indigenous communities.
Exploratory Data Analysis: Connecting X-Ray Diffraction and Lithogeochemical Data
Authors: Bringeland Stephanie
Published: April 2021

The Vazante Group is a district in east-central Brazil that consists of a carbonate-dominated marine platform sequence of Late Mesoproterozoic age. The district is home to a north-south belt that contains several zinc mines, but the petrogenesis of the ore body is not yet fully understood. Samples from this district were analyzed using both X-Ray Diffraction (XRD) and lithogeochemical assay techniques by Dr. Neil Fernandes in 2016. An analysis was conducted in order to explore the statistical correlations between the XRD and lithogeochemical test results. The purpose of the analysis was to determine whether the raw (uninterpreted) XRD data alone could be used to identify the samples enriched in zinc and other elements indicative of economic mineralization. The results showed very subtle trends that were not significant enough to make conclusions about the possibility of using XRD data without accompanying lithogeochemical data. The higher-than-average correlation of the intensity of pyrite peaks in the XRD data with elements associated with mineralization suggests that there are potentially more robust and significant trends that were not fully uncovered by this analysis, as pyrite has already been associated with mineralized zones. The analysis process itself could be valuable in future projects, and future work on this technique is proposed that uses machine learning to cluster the data and detect trends that may not be obvious using conventional techniques.
Grabbing Life by the Ballot: Creating an Effective Ballot through Design
Authors: McCoy Katharine
Published: April 2021

This presentation, reflecting a politics undergraduate thesis, will explore the design process behind the ballots that voters use in democratic elections around the world. Ballots are an inherently political objects, and in many cases, the most direct line of communication a citizen has to the government of their country. As such, the design of the ballot affects the legitimacy of higher level electoral and democratic institutions. This project argues that by co-opting the language of product design, a universal ballot design process would make more efficient ballots across the globe.

 

Product design starts with a brainstorming stage that explores at the user, the goal of the object, and the context of its use to create an effective design. By applying these observations to the process of designing a ballot, each electoral commission can produce a more effective ballot. Currently there is no standardization for ballot design other than ensuring that electoral commissions tried to make it “friendly.” By examining cases of bad ballot design, it is possible to see what element of the design process was missed or misused to create a process that corrects for these mistakes. This project examines poorly designed ballots in Florida, Scotland, and Colombia to explore the large-scale effects these small design choices make, and how to fix them.
Women at the Operatic Helm
Authors: Journeau Maia
Published: April 2021

The representation of women in opera, both on and off stage, has been an issue for all of opera’s 400-year history. In her now famous book Opera, or, the Undoing of Women (1979), Catherine Clement was one of the first to bring feminist theory to bear on opera scholarship, revealing true problems in the representation of operatic women on the stage in opera’s canon. But as I explore in this project, the same can be said for opera’s women behind the scenes. According to 2018 stats from OPERA America, out of the 786 total leadership positions held in North American houses, only 34.5% of administrative roles were occupied by women. 

 

In this proposed poster presentation, I will analyze the data from 1990 to the present with respect to the lack of gender parity in the opera industry in North America. I will also report on a series of interviews I conducted with several prominent female-identifying leaders in the opera industry, revealing currents in their narratives, and lessons for future women in this field. I will use this data to outline possible steps towards a more equitable opera industry. As Francesca Zambello, the most distinguished female director/general director in North America today, shared in a recent speech: “Opera needs truly excellent leadership to thrive, and when women are discouraged, it halves our pool of possibilities. We need leadership that is representative of the diverse audience we have and hope to grow.”
