Multitrophic interactions can strongly influence the structure and functioning of ecosystems, but how plant diversity influences the direction and predictability of multitrophic interactions across agricultural and natural ecosystems remains unclear. Using 149 field studies across five continents, we found that, on average, increasing plant diversity tended to exert differential top-down and bottom-up effects in croplands versus grasslands and forests. Organic and nonorganic croplands exhibited 846 and 148% higher invertebrate natural enemy-to-herbivore abundance ratios under increased plant diversity, consistent with top-down control patterns where predator gains cause herbivore declines, enhancing crop outcomes. In grasslands and forests, increasing plant diversity was associated …

Epigenetic Regulators Mll3 And Mll4 Sustain Hematopoietic Stem Cell Multipotency, Helen Chenwei Wang

Arts & Sciences Graduate Student Theses and Dissertations

Hematopoietic stem cells (HSCs) maintain lifelong blood production by balancing self-renewal and multilineage differentiation. They are sustained by networks of transcription factors and epigenetic regulators that prime lineage-specific programs while simultaneously preventing activation of any one program up until the moment of lineage commitment. Despite extensive study, it remains unclear how these complex transcriptional programs are coordinated and how specific epigenetic regulators are deployed to reinforce specific cell fate decisions. Epigenetic regulators, MLL3 and MLL4, play a central role in pluripotent embryonic stem cell fate transitions, but their functions in multipotent somatic stem cells are less well characterized. MLL3 (also …

Journal of Mechanical Engineering Science and Technology (JMEST)

The processes of moulding and reinforcing chemical elements have a big impact on the balance of chemical composition in copper-based bearing alloys. This has a direct impact on how well the material works. This study examines Cu–Sn alloys produced via sand casting and Cu–Zn alloys fabricated through permanent mould casting, with the incorporation of nickel, which remains uncommon. The objective was to examine the variations in the equilibrium of the chemical composition and the performance potential of the bearing alloy metal when subjected to different casting techniques and nickel concentrations ranging from 0% to 4%. Some of the methods used …

Exposing The Wizard Of Oz: Transparency And Testing Of Artificial Intelligence Systems, Henry H. Perritt

Journal of Science & Technology Law

The press and media, elected officials, some high-tech entrepreneurs, and a new breed of “ethicists” are calling loudly for governments to regulate artificial intelligence (“AI”), especially generative AI, popularized by ChatGPT and Google Gemini. Much of the clamor is ill-informed about the technology and based on exaggerated concerns about its risks. Nevertheless, the pressure for regulation is real and is already evoking governmental responses. Transparency requirements are far better than command-and-control regulation. The technology is far too new, however, for any form of command-and-control regulation. Would-be regulators need to take a deep breath and sit back for a while to …

Glassy Magnetic Freezing Of Interacting Clusters In Materials Related To The Lk-99 Family, Serafim Teknowijoyo, Domenico Napoletani, Vahan Nikoghosyan, Armen Gulian

Mathematics, Physics, and Computer Science Faculty Articles and Research

We report reproducible magnetization anomalies appearing below room temperature in copper-doped apatite materials belonging to the LK-99 family synthesized via hydrothermal methods. These anomalies are observed consistently across samples prepared under comparable conditions. Although the extracted Mydosh parameter lies within the range often associated with vortex-glass behavior in superconductors, a detailed analysis of DC magnetization, AC susceptibility, field dependence, and magnetic memory effects demonstrates that the observed phenomena are not related to superconductivity. Instead, the data are consistent with glassy magnetic freezing of interacting clusters. Compositional and structural analysis identifies covellite (CuS), one of the constituent phases in these multiphase …

Ƒ(Enlightenment): A Complex Adaptive Systems Model Of Recursive Causality And Human Meaning-Making, Daniel Lambert

Dissertations and Theses

Conflict Resolution has developed as a richly interdisciplinary field; however, its theoretical architecture remains fragmented across distinct bodies of scholarship. Existing approaches offer valuable but often isolated explanations of conflict behavior, limiting their ability to account for its complexity. This thesis addresses this limitation by advancing systems science as an organizing framework for integrating these perspectives. It introduces the Human-Complex Adaptive Systems (H-CAS) framework, which conceptualizes human behavior as a recursive adaptive process operating across interconnected regulatory domains. Within this model, conflict is not treated as a discrete event or purely deliberative process, but as an emergent property arising from …

We used OpenAI's embedding models to create vector representations of the collected data, allowing for accurate similarity assessments via Neo4j's built-in algorithms. By integrating this system with LangChain, we enabled natural language queries. The results demonstrated high …

Stylometric And Formal Patterns In The Scholarly Impact Of Scientific Literature, Joshua Ange, Eric Godat, Rajani Sudan

SMU Journal of Undergraduate Research

Scientific communication is typically tied to promoting public engagement and interest in science, increasing scientific literacy, and playing an essential role in policymaking. The success of public communication of scientific findings is largely associated with secondary characteristics of research (e.g. the style of writing and presentation), rather than the primary content or research quality. But it is unclear to what extent the success of scientific literature intended for working scientists is influenced by those same secondary characteristics. Does the writing style of scientific articles impact their success in academic spheres? In this study, we explore the stylometric and formal characteristics …

What Factors Do Patients Consider When Choosing A Hand Surgeon?, Monik Debkowska, Jeremy Ruskin, Brian Lynch, Samuel Caradonna, David Komatsu, Edward Wang, Samantha Muhlrad

Introduction: Many patients find themselves frustrated wasting time and money when searching for the right hand specialist, only to be referred to a different one. There has been little research evaluating patient decision making when choosing a hand surgeon. Specialists would benefit from learning how to optimize their practice to reach their appropriate patient population for maximum benefit and minimum resource waste, both for the patients and physicians. We therefore conducted a survey study to evaluate which factors patients consider important when choosing a hand surgeon, and if these factors differ based on patient demographics. Our hypothesis is that patients …

Myth, Spirituality, And Thought Patterns In Two African And Brazilian Ritual Dramas, Dele Layiwola

Global Africa: Journal of African and African Diaspora Studies

This essay conceptualizes and historicizes the phenomena of religion, custom, and belief systems by utilizing two celebrated dramatic texts and performances as practical illustrations of the complex roles they play in the social, political, and cultural lives of human beings, irrespective of their geographical locations. The arguments demonstrate that religion or spirituality is a given phenomenon in the personal and public lives of the denizens of various societies. It possesses its own logic and rules, which may not be mutually compatible, nevertheless constitute a constant universal principle. The paper employs dramatized examples to show that in classical or modern times, …

Ikenga: Symbolism, Spirituality, And Sociocultural Importance In Igbo Traditional Belief Systems, Chinyere Ndubuisi

Global Africa: Journal of African and African Diaspora Studies

The Ikenga, a noteworthy relic of the Igbo people of southern Nigeria, is examined in this paper as a major art object for a better understanding of African traditional religions and belief systems. Ikenga is a wooden sculpture traditionally made to represent an individual's power, achievements, and spiritual essence among the Igbo. Ikenga is ascribed the embodiment of the relationship between personal action, ancestral respect, and divinity within Igbo mythology. Within the framework of Igbo traditional religion, this paper examines the ontological significance, spiritual purposes, and social consequences of the Ikenga. The symbolic relevance of Ikenga as both a personal …

Language And Culture: Exploring The Links Between Africans And African Americans, Joash J. Gambarage

Global Africa: Journal of African and African Diaspora Studies

Due to the generational distance between contemporary African Americans and the earliest generations of enslaved Africans, the deep cultural connection between these two groups has not been sufficiently explored. Moreover, much of the existing literature on African culture in the Americas primarily focuses on retentions related to religion, music, food, and language, often missing other critical aspects of cultural continuity within the African diaspora, such as African American Vernacular English (AAVE) and Niger-Congo linguistic ties, naming practices, and African epistemologies. This exclusion limits our understanding of how the historical movement of Africans and the persistence of African cultural legacies, have …

Situating Everybody Hates Chris (Ehc): The Appeal Of The Show, Elizabeth Johnson, Donald Culverson

Global Africa: Journal of African and African Diaspora Studies

"Everybody Hates Chris" (EHC) achieved critical success by employing comedy to address significant social issues, distinguishing itself in early-2000s television. Unlike earlier and contemporary series such as "Moesha," "The Hughleys," and "The Cosby Show," EHC offered a nuanced portrayal of Black family life, engaging an audience often overlooked or misrepresented by mainstream media. This article examines shifts in the television industry from the late 1990s to the early 2000s that facilitated EHC's innovative approach. The series departed from traditional family sitcoms, functioning not merely as entertainment but as a social commentary on the complexities of the family as a societal …

Marcion And The Crisis Of Second-Century Christianity, Samuel Petersen

The Thetean: A Student Journal for Scholarly Historical Writing

Almost a century after the death of Christ and his original apostles, the 2nd-century Judeo-Christian church found itself in a vicious struggle for survival catalyzed by an ongoing negotiation between the church’s traditional Jewish roots and establishing its own identity. The loose confederation of Jesus-believers fought to gather themselves into a functional body as they wrestled with questions surrounding the very nature of the Christian faith.

“No Hen Should Herald The Dawn Lest Misfortune Follow”: Gender, History, And Power Sima Guang’S Comprehensive Mirror, Zoe Ngan

The Thetean: A Student Journal for Scholarly Historical Writing

It was not a particularly notable occasion when Emperor Gaozong 高宗 of the Tang dynasty (AD 618–907) established Wu Zetian 武則天 as a mid-ranked concubine in 654. Emperors, throughout Chinese history, were polygamous rulers who acquired no shortage of concubines per the Rites of Zhou 周禮, an ancient ritual text which proposed that rulers obtain 121 wives and consorts. Wu’s nomination signified the unpredictability of imperial favour and almost certainly did not turn heads when her appointment occurred.

“I, Too, Want To Be Free”: Women And The Birth Control Movement In Utah, 1914–1940, Evelyn Wilcox

The Thetean: A Student Journal for Scholarly Historical Writing

Like many other women, I too, want to be free,” explained a 33-year- old Utah woman in a 1925 letter to Margaret Sanger, a prominent leader in the birth control movement. This woman, whose name is unknown, was married to a 78-year- old man with whom, she thought, “in her ignorance,” that she would never have any children—she was proven wrong. With six children under the age of eight at the time and wanting to prevent having more, this woman’s predicament reflects Sanger’s mission to inform everyday women of birth control so they could make their own reproductive choices. After …

Rationed Victory: A Study Of American Civilian Rationing In World War Ii, Alex Moulder

The Thetean: A Student Journal for Scholarly Historical Writing

In any conflict or competition it is often said that the winner is “fueled to victory.” This could come as a result of training, diet, stamina, support from others, or sheer willpower. Even small variations in any of these elements can have significant consequences and affect outcomes. The same can be said about civilians during wartime, especially during the largest conflict of the twentieth century, World War II. The war cemented the United States as a global power, thanks in part to its massive economy, technologies, and industries, which helped to overcome the war of attrition against the Axis powers. …

“It Was The Women Who Kept It On”: The 1984–85 National Union Of Mineworkers Strike In Wales, Brett Bodily

The Thetean: A Student Journal for Scholarly Historical Writing

On March 3rd, 1984, more than 140,000 miners, all members of the National Union of Mineworkers (NUM) walked out on strike in protest of proposed colliery, or “pit” closures. Years of disputes culminated in a major showdown between the largest labor union in the United Kingdom and a resurgent national conservatism led by Margaret Thatcher— leader of the Tory party. The communities built around coal mining recognized the Tory pit closure plan for what it was—an existential threat to their way of life. Women within these communities rose to the occasion and took on leadership and organizational responsibilities, many for …
