Life On The Edge: The Cambrian Marine Realm And Oxygenation, Sara Pruss, Benjamin C. Gill May 2024

Life On The Edge: The Cambrian Marine Realm And Oxygenation, Sara Pruss, Benjamin C. Gill

Geosciences: Faculty Publications

The beginning of the Phanerozoic saw two biological events that set the stage for all life that was to come: (a) the Cambrian Explosion (the appearance of most marine invertebrate phyla) and (b) the Great Ordovician Biodiversification Event (GOBE), the subsequent substantial accumulation of marine biodiversity. Here, we examine the current state of understanding of marine environments and ecosystems from the late Ediacaran through the Early Ordovician, which spans this biologically important interval. Through a compilation and review of the existing geochemical, mineralogical, sedimentological, and fossil records, we argue that this interval was one of sustained low and variable marine …

Neighborhood Eviction Trajectories And Odds Of Moderate And Serious Psychological Distress During Pregnancy Among African American Women, Shawnita Sealy-Jefferson, Benita Jackson, Brittney Francis Mar 2024

Neighborhood Eviction Trajectories And Odds Of Moderate And Serious Psychological Distress During Pregnancy Among African American Women, Shawnita Sealy-Jefferson, Benita Jackson, Brittney Francis

Psychology: Faculty Publications

African American mothers are unjustly burdened both by residential evictions and psychological distress. We quantified associations between trajectories of neighborhood evictions over time, and odds of moderate and serious psychological distress (MPD and SPD, respectively) during pregnancy among African American women. We linked publicly available neighborhood eviction filing and judgement rate data to preconception and during pregnancy addresses from the Life-course Influences on Fetal Environments Study (2009-2011, n=808). Multinomial logistic regression estimated odds of MPD and SPD during pregnancy associated with eviction filing and judgement rate trajectories incorporating preconception and during pregnancy addresses (each categorized as low/medium/high, with two 9-category …


Foraminifera As A Model Of Eukaryotic Genome Dynamism, Caitlin Timmons, Kristine Le, H. B. Rappaport, Elinor G. Sterner, Xyrus X. Maurer-Alcaláh, Susan T. Goldstein, Laura A. Katz Mar 2024

Foraminifera As A Model Of Eukaryotic Genome Dynamism, Caitlin Timmons, Kristine Le, H. B. Rappaport, Elinor G. Sterner, Xyrus X. Maurer-Alcaláh, Susan T. Goldstein, Laura A. Katz

Biological Sciences: Faculty Publications

In contrast to the canonical view that genomes cycle only between haploid and diploid states, many eukaryotes have dynamic genomes that change content throughout an individual’s life cycle. However, the few detailed studies of microeukaryotic life cycles render our understanding of eukaryotic genome dynamism incomplete. Foraminifera (Rhizaria) are an ecologically important, yet understudied, clade of microbial eukaryotes with complex life cycles that include changes in ploidy and genome organization. Here, we apply fluorescence microscopy and image analysis techniques to over 2,800 nuclei in 110 cells to characterize the life cycle of Allogromia laticollaris strain Cold Spring Harbor (CSH), one of …


How Development And Survival Combine To Determine The Thermal Sensitivity Of Insects, Mariana Abarca, Anna L. Parker, Elise A. Larsen, James Umbanhowar, Chandra Earl, Robert Guralnick, Joel Kingsolver, Leslie Ries Jan 2024

How Development And Survival Combine To Determine The Thermal Sensitivity Of Insects, Mariana Abarca, Anna L. Parker, Elise A. Larsen, James Umbanhowar, Chandra Earl, Robert Guralnick, Joel Kingsolver, Leslie Ries

Biological Sciences: Faculty Publications

Thermal performance curves (TPCs) depict variation in vital rates in response to temperature and have been an important tool to understand ecological and evolutionary constraints on the thermal sensitivity of ectotherms. TPCs allow for the calculation of indicators of thermal tolerance, such as minimum, optimum, and maximum temperatures that allow for a given metabolic function. However, these indicators are computed using only responses from surviving individuals, which can lead to underestimation of deleterious effects of thermal stress, particularly at high temperatures. Here, we advocate for an integrative frame- work for assessing thermal sensitivity, which combines both vital rates and survival …

Exercise and Sport Studies: Faculty Publications

The years surrounding the transition to menopause are marked by multiple challenges to health. Hot flashes are a commonly reported symptom of women at this time and their frequency has been associated with disease risk. Regular physical activity and reduced sedentary time are recommended for health and wellbeing. However, the effect of physical activity and sedentary behavior on hot flashes remains unclear. OBJECTIVE: The purpose of this study was to evaluate relationships between physical activity, sedentary time and hot flashes during both waking and sleeping periods using concurrent objective and subjective measures of hot flashes in midlife women. METHODS: Women …

Exercise and Sport Studies: Faculty Publications

Objective: This study determined the association between acute changes in physical activity, temperature and humidity and 24-hour subjective and objective hot flash experience.

Methods: Data collection occurred during the cooler months of the year in Western Massachusetts (October-April). Women aged 45-55 across 3 menopause stages (n=270) were instrumented with ambulatory monitors to continuously measure hot flashes, physical activity, temperature and humidity for 24-hours. Objective hot flashes were assessed via sternal skin conductance, and subjective hot flashes were recorded by pressing an event marker and data logging. Physical activity was measured with wrist-worn accelerometers and used to define sleep and wake …


Extreme Ungrading: Rewilding The Classroom Through Human-Centered Design, Johanna Brewer Jan 2024

Extreme Ungrading: Rewilding The Classroom Through Human-Centered Design, Johanna Brewer

Computer Science: Faculty Publications

Assessment in computer science education has grown reliant on rigid rubrics and intensive exams, a practice that yields capable yet compliant coders. In this article, I explore how we might use human-centered design to reexamine contemporary pedagogy and redesign our classrooms to cultivate a different type of programmer, one with a more critically engaged eye. Inspired by the ethos of agile development, I offer an alternative evaluation paradigm: Extreme Ungrading. Exploring results of a two-year case study applying this method to a software engineering class, this article distills actionable guidelines for enhancing learning outcomes through inclusive course development, and seeks …

Teaching Chinese Politics In The “New Cold War”: A Survey Of Faculty, Sara A. Newland Nov 2023

Teaching Chinese Politics In The “New Cold War”: A Survey Of Faculty, Sara A. Newland

Government: Faculty Publications

How have worsening US-China relations affected faculty teaching Chinese politics in the US? This paper presents results from a 2022 survey of political science faculty. While student interest in Chinese politics remains high, faculty report a range of new challenges arising from increasingly nationalistic sentiments among both Chinese and American students, negative effects of both US and Chinese government policies, and an increase in anti-Asian bias. This article documents faculty experiences teaching Chinese politics, and offers recommendations for addressing common challenges.


Introduction To The Symposium: China And The Campus, Sara A. Newland Nov 2023

Introduction To The Symposium: China And The Campus, Sara A. Newland

Government: Faculty Publications

The US-China relationship has worsened dramatically in recent years. After decades of pro-engagement policies toward China, a bipartisan consensus began to emerge around 2016 that engagement had neither accomplished US policy goals (such as encouraging China to liberalize politically) nor served US citizens well.1 At the same time, political changes within China have pointed to a declining appetite for engagement with the United States and sidelined the domestic constituencies who remained interested in cooperation and exchange. Further restrictions have shrunk the already limited space for media, civil society groups, and academic exchange in China. Pandemic-related border closures eliminated in-person exchanges …


A Snapshot Into The Lives Of Elephants: Camera Traps And Conservation In Etosha National Park, Namibia, Jodie L. Berezin, Amanda J. Odom, Virginia Hayssen, Caitlin E. O'Connell-Rodwell Nov 2023

A Snapshot Into The Lives Of Elephants: Camera Traps And Conservation In Etosha National Park, Namibia, Jodie L. Berezin, Amanda J. Odom, Virginia Hayssen, Caitlin E. O'Connell-Rodwell

Biological Sciences: Faculty Publications

Knowledge of elephant movement and grouping patterns in the wild is critical for their management and conservation. Much of these data come from GPS collar data and aerial surveys, which have provided invaluable information, but data from these methods are often limited to small groups or entire populations. Effective elephant management requires both generalized and localized methodologies. Here, we propose the expanded use of camera traps in research relating to elephant localized movements and grouping patterns as an additional tool for elephant conservation management. In this study, we use a battery-powered camera trap to provide daily high-resolution data of African …


Wide Range Thin-Film Ceramic Metal-Alloy Thermometers With Low Magnetoresistance, Nathanael Fortune, Joyce E. Palmer-Fortune, A. Trainer, A. Bangura, N. Kondedan, A. Rydh Nov 2023

Wide Range Thin-Film Ceramic Metal-Alloy Thermometers With Low Magnetoresistance, Nathanael Fortune, Joyce E. Palmer-Fortune, A. Trainer, A. Bangura, N. Kondedan, A. Rydh

Physics: Faculty Publications

Many thermal measurements in high magnetic fields require thermometers that are sensitive over a wide temperature range, are low mass, have a rapid thermal response, and have a minimal, easily correctable magnetoresistance. Here we report the development of a new granular-metal oxide ceramic composite (cermet) for this purpose formed by co-sputtering of the metallic alloy nichrome Ni0.8Cr0.2 and the insulator silcon dioxide SiO2. The resulting thin films are sensitive enough to be used from room temperature down to below 100 mK in magnetic fields up to at least 35 tesla.

Exercise and Sport Studies: Faculty Publications

This study investigated trauma prevalence amongst collegiate student-athletes and openness towards trauma-informed coaching practices among athletes and coaches at two small Division III colleges. Surveys gathered quantitative data from athletes (n = 91) and coaches (n =18) and qualitative data from athletes (n = 33). Quantitative results indicated that 52.7% of athletes experienced at least one potentially traumatic event during their lifetime. The most prevalent trauma was unwanted sexual contact. Additionally, 50.5% of athletes experienced sport-based harassment or abuse during their lifetime, with 21.7% of affected athletes experiencing said abuse in college sports. Athletes reported that 8 out of 10 …

Sociology: Faculty Publications

This interview with Doris H. Gray, author of Leaving the Shadow of Pain: A Cross-cultural Exploration of Truth, Trauma, Reconciliation, and Healing, explores the impact of political trauma across time, and the strategies for healing and justice. The conversation with Gray focuses on the ways in which her own experiences, as the child of a traumatized German Jew, intersect with those of formerly persecuted and incarcerated Tunisian women before and after the Arab Spring. What are the possibilities and limitations of restorative justice for those haunted by history?


Meridians: 22:2 Mosaic, Ginetta Candelario Oct 2023

Meridians: 22:2 Mosaic, Ginetta Candelario

Sociology: Faculty Books

According to the Oxford English Dictionary, a mosaic is “a variegated whole formed from many disparate parts,”1 which perfectly captures this issue’s geographically, historically, intellectually, and artistically wide-ranging, and diverse yet interrelated contents. Each piece—whether poetry, testimonio, essay, creative nonfiction, or interview—touches on key themes iterated in unique ways depending on the context. Featuring work focused on Afghanistan, Canada, Haiti, India, Mexico, Tunisia, Turkey, Sri Lanka, Puerto Rico, and the United States mainland, this Mosaic issue reveals a broader picture of the complex, contradictory, and challenging nature of enacting transnational or intersectional feminist solidarities within and across …


Two Cardinal Portraits By Scipione Pulzone In The Harvard Art Museums And Their Related Versions, Danielle Carrabino Sep 2023

Two Cardinal Portraits By Scipione Pulzone In The Harvard Art Museums And Their Related Versions, Danielle Carrabino

Museum of Art: Books

Book abstract:

The visual legacy of early modern cardinals constitutes a vast and extremely rich body of artworks, many of superb quality, in a variety of media, often by well-known artists and skilled craftsmen. Yet cardinal portraits have primarily been analyzed within biographical studies of the represented individual, in relation to the artists who created them, or within the broader genre of portraiture. Portrait Cultures of the Early Modern Cardinal addresses questions surrounding the production, collection, and status of the cardinal portrait, covering diverse geographies and varied media. Examining the development of cardinals' imagery in terms of their multi-layered identities, …


Effect Of Tamoxifen On Proteome Expression During In Vitro Myogenesis In Murine Skeletal Muscle C2C12 Cells, Emily A. Morris, Ahlenne Abreu, S. P. Scordilis Aug 2023

Effect Of Tamoxifen On Proteome Expression During In Vitro Myogenesis In Murine Skeletal Muscle C2C12 Cells, Emily A. Morris, Ahlenne Abreu, S. P. Scordilis

Biological Sciences: Faculty Publications

Tamoxifen (TMX), a selective estrogen receptor modulator, is commonly used in the treatment of hormone-responsive cancers. However, the effects of TMX in anabolic tissues harboring estrogen receptors, such as skeletal muscle, are poorly understood. We report a tandem mass-tag approach to TMX-treated myogenesis in C2C12 cells, a well-characterized model of in vitro murine skeletal muscle differentiation. A longitudinal analysis of >10,000 proteins identified in untreated C2C12 myogenesis revealed a novel subset of 1,062 myogenically regulated proteins. These proteins clustered into five distinct longitudinal expression trends which significantly overlap those obtained in similar analyses performed …


Social Contagion Of Nonsuicidal Self-Injury, Stephaie Jarvi Steele Aug 2023

Social Contagion Of Nonsuicidal Self-Injury, Stephaie Jarvi Steele

Psychology: Faculty Books

This chapter explores the social contagion of nonsuicidal self-injury (NSSI) via interpersonal, media and online exposure among both youths and adults by referencing social learning theory and the Social Exposure to Non-Suicidal Self-Injury Scale. According to social learning theory, people imitate and learn certain behaviors by identifying with people who act as models. The chapter elaborates on the concepts of social learning, modeling, and imitation, and general recommendations for the assessment and treatment of clinical practice addressing social contagion factors. It then suggests utilizing ecological momentary assessment (EMA) and single-case experimental design (SCED) for future studies on social contagion of …


A World Of Difference: The Fundamental Opposition Between Transhumanist “Welfarism” And Disability Advocacy, Susan B. Levin Jul 2023

A World Of Difference: The Fundamental Opposition Between Transhumanist “Welfarism” And Disability Advocacy, Susan B. Levin

Philosophy: Faculty Publications

From the standpoint of disability advocacy, further exploration of the concept of well-being stands to be availing. The notion that “welfarism” about disability, which Julian Savulescu and Guy Kahane debuted, qualifies as helpful is encouraged by their claim that welfarism shares important commitments with that advocacy. As becomes clear when they apply their welfarist frame to procreative decisions, endorsing welfarism would, in fact, sharply undermine it. Savulescu and Kahane's Principle of Procreative Beneficence—which reflects transhumanism, or advocacy of radical bioenhancement—morally requires parents to choose the child who will, in all probability, have “the best life.” Assuming the emergence of potent …


Temperature And Convictions: Evidence From India, Terry Ann Craigie, Vis Taraz, Mariyana Zapryanova Jul 2023

Temperature And Convictions: Evidence From India, Terry Ann Craigie, Vis Taraz, Mariyana Zapryanova

Economics: Faculty Publications

High temperatures have been shown to affect human cognition and decision-making in a variety of settings. In this paper, we explore the extent to which higher temperatures affect judicial decision-making in India. We use data on judicial decisions from the Indian eCourt platform, merged with high-resolution gridded daily weather data. We estimate causal effects by leveraging a fixed effects framework. We find that high daily maximum temperatures raise the likelihood of convictions and these results are robust to numerous controls and specifications. Our findings contribute to a growing literature that documents that the negative impacts of rising temperatures are often …


Differentiating Between Us & Them: Reduced In-Group Bias As A Novel Mechanism Linking Childhood Violence Exposure With Internalizing Psychopathology, Steven W. Kasparek, Maya L. Rosen, Lucy A. Lurie, Mina Cikara, Kelly Sambrook, Dario Cvencek, Andrew N. Meltzoff, Katie A. Mclaughlin Jul 2023

Differentiating Between Us & Them: Reduced In-Group Bias As A Novel Mechanism Linking Childhood Violence Exposure With Internalizing Psychopathology, Steven W. Kasparek, Maya L. Rosen, Lucy A. Lurie, Mina Cikara, Kelly Sambrook, Dario Cvencek, Andrew N. Meltzoff, Katie A. Mclaughlin

Neuroscience: Faculty Publications

Strong in-group bonds, facilitated by implicit favoritism for in-group members (i.e., in-group bias), promote mental health across development. Yet, we know little about how the development of in-group bias is shaped by early-life experiences. Childhood violence exposure is known to alter social information processing biases. Violence exposure may also influence social categorization processes, including in-group biases, in ways that influence risk for psychopathology. We examined associations of childhood violence exposure with psychopathology and behavioral and neural indices of implicit and explicit bias for novel groups in children followed longitudinally across three time points from age 5 to 10 years old …


Humans Against Large Language Models On Hard Paraphrase Detection Tasks, Jamie C. Macbeth, Ella Chang, Jingyu Gin Chen, Yining Hua, Sandra Grandic, Winnie X. Zheng Jul 2023

Humans Against Large Language Models On Hard Paraphrase Detection Tasks, Jamie C. Macbeth, Ella Chang, Jingyu Gin Chen, Yining Hua, Sandra Grandic, Winnie X. Zheng

Computer Science: Faculty Publications

The ability to recognize that pairs or sets of language expressions “mean the same thing” is a cognitive task for which meaning representation is clearly a central issue. This paper uses the task of paraphrasing to study meaning representation in a cognitive system. The main claim is that a consequential part of the meaning representation for a natural language expression is a set of language-free structures that are not part of the expression in question. To support this claim, we construct a corpus of paraphrase pairs using a system that has a non-linguistic meaning represen- tation decoupled from the linguistic …


Creating A Feminist Religious Counterpublic:Rlds Feminists And Women's Ordination Advocacy In America, 1970–1985, David Howlett, Nancy Ross Jul 2023

Creating A Feminist Religious Counterpublic:Rlds Feminists And Women's Ordination Advocacy In America, 1970–1985, David Howlett, Nancy Ross

Religion: Faculty Publications

The 1970s witnessed an efflorescence of religious feminism in the Reorganized Church of Jesus Christ of Latter Day Saints, particularly around the issue of women's ordination. We pose a model for understanding this development—the formation of publics/counterpublics—and explore how it illuminates our case study. Drawing upon oral history interviews and archival sources, we document how RLDS women created independent publications, grassroots consciousness-raising groups, feminist classes and conferences, and Women-Church–inspired worship to reimagine priesthood within their church. We conclude that the lens of a counterpublic offers a capacious view of our topic, one capable of integrating both social movement theory and …


Assessing The Language Of 2-Year-Olds: From Theory To Practice, Emily Jackson, Dani Levine, Jill De Villiers, Aquiles Iglesias, Kathy Hirsh-Pasek, Roberta Michnick Golinkoff Jun 2023

Assessing The Language Of 2-Year-Olds: From Theory To Practice, Emily Jackson, Dani Levine, Jill De Villiers, Aquiles Iglesias, Kathy Hirsh-Pasek, Roberta Michnick Golinkoff

Philosophy: Faculty Publications

Early screening for language problems is a priority given the importance of language for success in school and interpersonal relationships. The paucity of reliable behavioral instruments for this age group prompted the development of a new touchscreen language screener for 2-year-olds that relies on language comprehension. Developmental literature guided selection of age-appropriate markers of language disorder risk that are culturally and dialectally neutral and could be reliably assessed. Items extend beyond products of linguistic knowledge (vocabulary and syntax) and tap the process by which children learn language, also known as fast mapping. After piloting an extensive set of items (139), …


Functional Network Reconfiguration Supporting Memory-Guided Attention, Kylie Isenburg, Thomas M. Morin, Maya L. Rosen, David C. Somers, Chantal E. Stern Jun 2023

Functional Network Reconfiguration Supporting Memory-Guided Attention, Kylie Isenburg, Thomas M. Morin, Maya L. Rosen, David C. Somers, Chantal E. Stern

Neuroscience: Faculty Publications

Studies have identified several brain regions whose activations facilitate attentional deployment via long-term memories. We analyzed task-based functional connectivity at the network and node-specific level to characterize large-scale communication between brain regions underlying long-term memory guided attention. We predicted default mode, cognitive control, and dorsal attention subnetworks would contribute differentially to long-term memory guided attention, such that network-level connectivity would shift based on attentional demands, requiring contribution of memory-specific nodes within default mode and cognitive control subnetworks. We expected that these nodes would increase connectivity with one another and with dorsal attention subnetworks during long-term memory guided attention. Additionally, we …

Astronomy: Faculty Publications

Accreting protoplanets are windows into planet formation processes, and high-contrast differential imaging is an effective way to identify them. We report results from the Giant Accreting Protoplanet Survey (GAPlanetS), which collected Hα differential imagery of 14 transitional disk host stars with the Magellan Adaptive Optics System. To address the twin challenges of morphological complexity and point-spread function instability, GAPlanetS required novel approaches for frame selection and optimization of the Karhounen-Loéve Image Processing algorithm pyKLIP. We detect one new candidate, CS Cha “c,” at a separation of 68 mas and a modest Δmag of 2.3. We recover the HD 142527 B …


Direct Election, Bureaucratic Appointment, And Local Government Responsiveness In Taiwan, Sara A. Newland Jun 2023

Direct Election, Bureaucratic Appointment, And Local Government Responsiveness In Taiwan, Sara A. Newland

Government: Faculty Publications

Does local democracy induce better service to citizens? While elected officials can be punished at the ballot box if they fail to address citizens’ needs, appointed bureaucrats may have policy knowledge that enables them to better serve citizens. Employing a multimethod design, this paper uses variation in local political institutions in Taiwan to assess the relative merits of direct election and bureaucratic appointment for local government responsiveness. While democratic institutions are often thought to induce responsiveness, I find that in Taiwan, with its historically strong bureaucracy and relatively new democratic institutions, the picture is somewhat more complicated. Elected and appointed …
