Unveiling The Librarian Of Tomorrow: Why Librarians Are Needed Now More Than Ever, Essraa Nawar Apr 2024

Unveiling The Librarian Of Tomorrow: Why Librarians Are Needed Now More Than Ever, Essraa Nawar

Library Articles and Research

"I fell in love with Libraries the moment I set foot in the Bibliotheca Alexandrina in Alexandria, Egypt, where I had the privilege of working for five enriching years. The Bibliotheca Alexandrina stands as a modern reincarnation of the legendary ancient library, a beacon of learning and exchange. Reflecting on its revival, I marvel at the timeless significance of libraries throughout history. From the fabled repositories of knowledge in Alexandria, Athens, and Constantinople to their contemporary counterparts, libraries have endured as bastions of enlightenment and progress. The spirit of international collaboration that birthed the Bibliotheca Alexandrina underscores the global significance …


Who Helps Tsimane Children And Adults?, Eric Schniter, Daniel K. Cummings, Paul L. Hooper, Maguin Gutierrez Cayuba, Jonathan Stieglitz, Benjamin C. Trumble, Hillard S. Kaplan, Michael D. Gurven Apr 2024

Who Helps Tsimane Children And Adults?, Eric Schniter, Daniel K. Cummings, Paul L. Hooper, Maguin Gutierrez Cayuba, Jonathan Stieglitz, Benjamin C. Trumble, Hillard S. Kaplan, Michael D. Gurven

ESI Working Papers

We consider several forms of helping behavior among Tsimane Amerindians of Bolivia, including provision of shelter, childcare, food, sickcare, loans, advice, and cultural influence. While kin selection theory is traditionally invoked to explain nepotistic nurturing of youngsters by closely related kin, much less attention has been given to understanding the help provided to children and adults by individuals without close genetic relatedness. To explain who provides the various forms of help that we consider, we evaluate support for several predictions derived from kin selection theory: that helpers are most often closely related and from an older generation, provide more help …

What If We No Longer Call It Dei?, Essraa Nawar Mar 2024

What If We No Longer Call It Dei?, Essraa Nawar

Library Articles and Research

"The persistent debate surrounding the term DEI reveals a broader dissatisfaction with its perceived limitations and the misunderstandings around its true meanings and concepts. As DEI initiatives face de-funding and positions are eliminated, there's a risk of the term becoming diluted, associated more with performative gestures than genuine structural change.

This backlash against DEI also signifies a growing disappointment with 'buzzword-driven' approaches to diversity and inclusion, underscoring the need for a deeper understanding of equity and justice. In the middle of this critique, the idea of renaming DEI emerges as a means of revitalizing the discourse and re-centering efforts on …

Mathematics, Physics, and Computer Science Faculty Articles and Research

In a recent paper, we extended a previous study on the solar solar influence to the generation of the March 2012 heatwave in the northeastern USA. In the present study we check the possible relationship of solar activity with the early March 2012 bad weather in northeast Thrace, Greece. To this end, we examined data from various remote sensing instrumentation monitoring the Sun (SDO satellite), Interplanetary space (ACE satellite), the Earth’s magnetosphere (Earth-based measurements, NOAA-19 satellite), the top of the clouds (Terra and Aqua satellites), and the near ground atmosphere. Our comparative data analysis suggests that: (i) the winter-like weather …


Understanding Unique Employability Skill Sets Of Autistic Individuals: A Systematic Review, Amy Jane Griffiths, Rachel Torres, Raquel Delgado, Amy E. Hurley-Hanson, Cristina M. Giannantonio, Wallace Walrod, Zachary Maupin, John Brady Mar 2024

Understanding Unique Employability Skill Sets Of Autistic Individuals: A Systematic Review, Amy Jane Griffiths, Rachel Torres, Raquel Delgado, Amy E. Hurley-Hanson, Cristina M. Giannantonio, Wallace Walrod, Zachary Maupin, John Brady

Education Faculty Articles and Research

In recent years, several publications and media outlets have highlighted how the skills and interests of autistic individuals may benefit organizations. However, there is scant empirical research on the topic. The present study's authors conducted a systematic review to find which potential employability skills, strengths, and interests of autistic individuals available research has highlighted. Data extraction methods identified 51 papers related to skills in this population. The skill sets autistic individuals may possess and the research behind these findings were organized, evaluated, and summarized. Based on these findings, investigators discuss implications for employment counseling and future research.

Institute for ECHO Articles and Research

In California (CA), the wildland-urban interface (WUI) faces escalating challenges due to surging population and real estate development. This study evaluates communities along CA's WUI that have witnessed substantial population growth from 2010 to 2021, utilizing demographic data and the 2020 WUI boundaries by the University of Wisconsin-Madison SILVIS Lab. Employing the Mann-Kendall test, we analyze yearly population trends for each census tract along the CA WUI and assess their significance. House ownership, affordability, and wildfire risk are examined as potential drivers of this demographic shift. Our findings indicate that 12.7% of CA's total population now resides in census tracts …


Compassionate Noticing And Stopping The Action: Bringing Intentionally Emergent Teaching Into Leadership Education, Tara Widner, Linnette Werner Mar 2024

Compassionate Noticing And Stopping The Action: Bringing Intentionally Emergent Teaching Into Leadership Education, Tara Widner, Linnette Werner

Education Faculty Articles and Research

Emergent-based practices of leadership development (such as intentional emergence (IE), case-in-point, or group relations) rely a great deal on stopping the action in order to publicly notice group behaviors and patterns and connect what is happening authentically to conscious actions and ideas (such as course content, readings, theories, etc.). However, when a facilitator or participant practices stopping the action and calling out these behaviors, there is a danger that they will go beyond productive tension into a level that causes casualties. This article explores the foundational need for compassion and purpose when using the common tools of heat and noticing …


Make It Funky For Me: Black British Women’S Explorations Of Britishness, Womanhood, And Artistry Through 2000s Music, Monique Charles Mar 2024

Make It Funky For Me: Black British Women’S Explorations Of Britishness, Womanhood, And Artistry Through 2000s Music, Monique Charles

Sociology Faculty Articles and Research

2000s Britain was an interesting and expansive time musically for Black Britain (Bradley 2013), as underground music gained traction in mainstream spaces. This article examines the context in which Black British women were able to cross over into the British mainstream and explores how U.K. garage and U.K. funky artists expressed their creativity, autonomy, womanhood, Blackness, and Britishness. Female U.K. garage artists set a precedent in the creation of “new” diverse identities for Black British women artists, but artists in both underground and mainstream music scenes were also forced to contend with restrictive and harmful misogynoir.


Ambiguity And Ambiguity Attitudes Across Auctions, Cary Deck, Paan Jindapon, Tigran Melkonyan, Mark Schneider Mar 2024

Ambiguity And Ambiguity Attitudes Across Auctions, Cary Deck, Paan Jindapon, Tigran Melkonyan, Mark Schneider

ESI Working Papers

Studies of ambiguity perceptions and attitudes are moving beyond the Ellsberg urn to examine people’s responses to ambiguity in naturally occurring events, games, and financial markets. In this study, we measure ambiguity perceptions and attitudes for market prices and allocations in four classical auction formats (first-price and second-price sealed bid auctions, English and Dutch clock auctions). We find ambiguity attitudes, representing individual preferences, are stable across auctions. However, the perceived ambiguity surrounding auction prices is lowest for English clock auctions which are obviously strategyproof (OSP), followed by second-price auctions which are strategyproof (SP), followed by a tie between first-price and …

Cognitive Abilities And Individual Earnings In Hybrid Continuous Double Auctions, Yan Peng, Jason Shachat, Lijia Wei, S. Sarah Zhang Feb 2024

Cognitive Abilities And Individual Earnings In Hybrid Continuous Double Auctions, Yan Peng, Jason Shachat, Lijia Wei, S. Sarah Zhang

ESI Working Papers

We study the influence of cognitive abilities, in particular reaction time, trader intuition (Theory of Mind), and cognitive reflection abilities, on human participants’ individual earnings when competing alongside algorithmic traders in continuous double auctions. In balanced markets, where each human trader has an algorithmic trader clone with the same valuations or costs, faster human reaction time significantly improves trading performance, while Theory of Mind can be detrimental to human trading performance, particularly for sellers. For unbalanced markets with humans and algorithmic traders on opposite sides of the market, the effects of cognitive abilities depend on trader role as well as …

Coordinated And Uncoordinated Punishment In A Team Investment Game, Vicente Calabuig, Natalia Jiménez-Jiménez, Gonzalo Olcina, Ismael Rodriguez-Lara Feb 2024

Coordinated And Uncoordinated Punishment In A Team Investment Game, Vicente Calabuig, Natalia Jiménez-Jiménez, Gonzalo Olcina, Ismael Rodriguez-Lara

ESI Publications

Coordinated punishment occurs when punishment requires a specific number of punishers to be effective, otherwise, no damage will be inflicted on the target. While societies often rely on this punishment device, its benefits are unclear compared to uncoordinated punishment, where punishment decisions are substitutes. In this paper, we compare the efficacy of coordinated and uncoordinated punishment in a team investment game with two investors and one allocator. Our findings indicate that coordinated punishment results in higher levels of cooperation and reciprocity, as measured by the levels of joint investment and the return by allocators. Importantly, this does not translate into …


Annual Research Review: The Power Of Predictability – Patterns Of Signals In Early Life Shape Neurodevelopment And Mental Health Trajectories, Elysia Poggi Davis, Laura M. Glynn Feb 2024

Annual Research Review: The Power Of Predictability – Patterns Of Signals In Early Life Shape Neurodevelopment And Mental Health Trajectories, Elysia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

The global burden of early life adversity (ELA) is profound. The World Health Organization has estimated that ELA accounts for almost 30% of all psychiatric cases. Yet, our ability to identify which individuals exposed to ELA will develop mental illness remains poor and there is a critical need to identify underlying pathways and mechanisms. This review proposes unpredictability as an understudied aspect of ELA that is tractable and presents a conceptual model that includes biologically plausible mechanistic pathways by which unpredictability impacts the developing brain. The model is supported by a synthesis of published and new data illustrating the significant …

INTRODUCTION

We address the extent to which adolescent cognition predicts dementia risk in later life, mediated by educational attainment and occupational complexity.

METHODS

Using data from Project Talent Aging Study (PTAS), we fitted two structural equation models to test whether adolescent cognition predicts cognitive impairment (CI) and Ascertain Dementia 8 (AD8) status simultaneously (NCognitive Assessment = 2477) and AD8 alone (NQuestionnaire = 6491) 60 years later, mediated by education and occupational complexity. Co-twin control analysis examined 82 discordant pairs for CI/AD8.

RESULTS

Education partially mediated the effect of adolescent cognition on CI in the cognitive assessment aample and …


How Does Passive Investing Effect The Informational Efficiency Of Prices?, Brice Corgnet, Mark Desantis, Yan Peng, David Porter, Jason Shachat Feb 2024

How Does Passive Investing Effect The Informational Efficiency Of Prices?, Brice Corgnet, Mark Desantis, Yan Peng, David Porter, Jason Shachat

ESI Working Papers

We investigate the causal effects of passive investing on informational efficiency and market quality metrics by developing a novel laboratory experiment that introduces Index trackers with exogenous passive investment flows. We find that, while improving liquidity, Index tracking hurts informational efficiency, confirming our main hypothesis. Furthermore, we observe violations of the law of one price, leading to widespread and persistent arbitrage opportunities. Additionally, our research uncovers that Active traders, particularly those with private information about asset values and high cognitive ability, reap benefits from the introduction of Index tracking.

Economics Faculty Articles and Research

The rapid growth of cultural evolutionary science, its expansion into numerous fields, its use of diverse methods, and several conceptual problems have outpaced corollary developments in theory and philosophy of science. This has led to concern, exemplified in results from a recent survey conducted with members of the Cultural Evolution Society, that the field lacks ‘knowledge synthesis’, is poorly supported by ‘theory’, has an ambiguous relation to biological evolution and uses key terms (e.g. ‘culture’, ‘social learning’, ‘cumulative culture’) in ways that hamper operationalization in models, experiments and field studies. Although numerous review papers in the field represent and categorize …


Temporal Relation Between Pubertal Development And Peer Victimization In A Prospective Sample Of Us Adolescents, Jessica A. Marino, Elysia Poggi Davis, Laura M. Glynn, Curt A. Sandman, Jennifer Hahn-Holbrook Feb 2024

Temporal Relation Between Pubertal Development And Peer Victimization In A Prospective Sample Of Us Adolescents, Jessica A. Marino, Elysia Poggi Davis, Laura M. Glynn, Curt A. Sandman, Jennifer Hahn-Holbrook

Psychology Faculty Articles and Research

Peer victimization typically peaks in early adolescence, leading researchers to hypothesize that pubertal timing is a meaningful predictor of peer victimization. However, previous methodological approaches have limited our ability to parse out which puberty cues are associated with peer victimization because gonadal and adrenal puberty, two independent processes, have either been conflated or adrenal puberty timing has been ignored. In addition, previous research has overlooked the possibility of reverse causality—that peer victimization might drive pubertal timing, as it has been shown to do in non-human primates. To fill these gaps, we followed 265 adolescents (47% female) prospectively across three-time points …


Sleep Restriction Alters The Integration Of Multiple Information Sources In Probabilistic Decision-Making, Jeryl Y. L. Lim, Johanna M. Boardman, Clare Anderson, David L. Dickinson, Daniel Bennett, Sean P. A. Drummond Feb 2024

Sleep Restriction Alters The Integration Of Multiple Information Sources In Probabilistic Decision-Making, Jeryl Y. L. Lim, Johanna M. Boardman, Clare Anderson, David L. Dickinson, Daniel Bennett, Sean P. A. Drummond

ESI Publications

The detrimental effects of sleep loss on overall decision-making have been well described. Due to the complex nature of decisions, there remains a need for studies to identify specific mechanisms of decision-making vulnerable to sleep loss. Bayesian perspectives of decision-making posit judgement formation during decision-making occurs via a process of integrating knowledge gleaned from past experiences (priors) with new information from current observations (likelihoods). We investigated the effects of sleep loss on the ability to integrate multiple sources of information during decision-making by reporting results from two experiments: the first implementing both sleep restriction (SR) and …


Representation And Bracketing In Repeated Games, Mouli Modak Feb 2024

Representation And Bracketing In Repeated Games, Mouli Modak

ESI Working Papers

In this experimental paper, the author investigates the framing effect of different representations of multiple strategic settings or games on a player’s strategic behavior. Two representations of the same environment are employed, wherein a player engages in two infinitely repeated prisoner’s dilemma games. In the first representation (termed Split), the stage games are shown separately. In contrast, the second representation (termed Linked) displays a combined stage game. The choice bracketing, distinguishing between Narrow and Broad bracketing, is considered a potential cause behind any disparity in behavior between the two representations. The Split representation does not necessitate broad bracketing, whereas the …

Ontological Complexity Of Interpolity Orders: The Encounter Between Chosŏn And Tibet In Qing, Inho Choi, Minju Kwon Jan 2024

Ontological Complexity Of Interpolity Orders: The Encounter Between Chosŏn And Tibet In Qing, Inho Choi, Minju Kwon

Political Science Faculty Articles and Research

This article examines the ontological complexity of interpolity orders with a focus on peripheral polities in the Qing order. Existing multiculturalist studies of the Qing order emphasized diverse cultural representations of a single imperial reality, lacking an understanding of multiple realities experienced by peripheral participants. Our analysis reveals the ontological complexity—rather than cultural diversity—of the Qing order, in which multiple ontological agents experienced different lived worlds, from the encounter between Chosŏn Korean envoys and the Tibetan Panchen Lama at Emperor Qianlong’s birthday ceremony. By analyzing the Chosŏn envoy member Pak Chiwŏn’s travelog and Tibetan records, we argue that the Chosŏn …

Mathematics, Physics, and Computer Science Faculty Articles and Research

The China Seismo-Electromagnetic Satellite (CSES), with a sun-synchronous orbit at 507 km altitude, was launched on 2 February 2018 to investigate pre-earthquake ionospheric anomalies (PEIAs) and ionospheric space weather. The CSES probes manifest longitudinal features of four-peak plasma density and three plasma depletions in the equatorial/low-latitudes as well as mid-latitude troughs. CSES plasma and the total electron content (TEC) of the global ionosphere map (GIM) are used to study PEIAs associated with a destructive M7.0 earthquake and its followed M6.5 and M6.3/M6.9 earthquakes in Lombok, Indonesia, on 5, 17, and 19 August 2018, respectively, as well as to examine ionospheric …


Perceived Neighborhood Disorder And Type 2 Diabetes Disparities In Hispanic, Black, And White Americans, Min Ying Yu, Alfredo J. Velasquez, Belinda Campos, Jennifer W. Robinette Jan 2024

Perceived Neighborhood Disorder And Type 2 Diabetes Disparities In Hispanic, Black, And White Americans, Min Ying Yu, Alfredo J. Velasquez, Belinda Campos, Jennifer W. Robinette

Psychology Faculty Articles and Research

Introduction: Approximately 32 million Americans have type 2 diabetes, and that number continues to grow. Higher prevalence rates are observed among certain subgroups, including members of marginalized racial/ethnic groups as well as residents of disordered neighborhoods (i.e., those with more trash and vandalism). Institutionalized discriminatory practices have resulted in disproportionate representation of marginalized racial/ethnic groups in disordered neighborhoods compared to non-Hispanic Whites. These neighborhood disparities may partially contribute to health disparities, given that signs of neighborhood disorder often relate to a general withdrawal from the neighborhood, minimizing opportunities for both physical and social engagement. Yet, research suggests variability across …


How Personalized Networks Can Limit Free Riding: A Multi-Group Version Of The Public Goods Game, Aaron S. Berman, Laurence R. Iannaccone, Mouli Modak Jan 2024

How Personalized Networks Can Limit Free Riding: A Multi-Group Version Of The Public Goods Game, Aaron S. Berman, Laurence R. Iannaccone, Mouli Modak

ESI Working Papers

People belong to many different groups, and few belong to the same network of groups. Moreover, people routinely reduce their involvement in dysfunctional groups while increasing involvement in those they find more attractive. The net effect can be an increase in overall cooperation and the partial isolation of free-riders, even if free-riders are never punished, excluded, or recognized. We formalize and test this conjecture with an agent-based social simulation and a multi-good extension of the standard repeated public goods game. Our initial results from three treatments suggest that the multi-group setting indeed raises overall cooperation and dampens the impact of …
