The association between social media use and loneliness is examined at the trait level and change in loneliness over time. Next, the use of social media during the COVID pandemic and its use to increase belonging at the momentary or daily level are summarized. Following, the use of social media to cope with loneliness or ostracism as well as the social compensation and enhancement hypotheses are examined. The evidence suggests social media use is weakly related to trait loneliness, explains little variance in loneliness relative to other predictors, and fails to explain a change in loneliness over time. There is no evidence it causes loneliness. On any given day, however, social media use may be used to promote belongingness but may not be a good means of coping with loneliness in the long term. This narrative review concludes that future research should firmly situate the study of loneliness and social media in the context of social interactions and relationships by carefully examining when and for whom it is beneficial or harmful

Anodically Grown Pt(II) Oxide Microelectrode/Nanoelectrode pH Sensor
No full textThese are the slides from a presentation given at the 2024 AICHE Annual Meeting on 10/29/2024.Platinum electrode availability in electrochemical laboratories makes it attractive as a potentiometric solid-state pH sensor for aqueous solutions. However, challenges have been reported in fabricating anodic-grown platinum oxide potentiometric pH sensors. In this work, cyclic voltammetry in 0.5 M H2SO4 and 1 M NaOH was conducted to assess the effect of acidic and basic solutions on the anodic-grown platinum (II) oxide for designing Pt/Pt(II) oxide pH sensor. Chronoamperometry was also employed to grow a platinum (II) oxide layer on an ultramicroelectrode in both solutions, followed by measuring their potentiometric response in various pH solutions. The platinum (II) oxide manufactured in 1 M NaOH showed a close Nernstian response (~ -60 mV/pH), and was insensitive to dissolved oxygen, cation and anion identities, and molar ionic strength. When the platinum (II) oxide was grown on a platinum nanoelectrode, the response time was ~ 2 seconds for an approximately twelve-fold pH step change. These findings highlight the importance of the solution pH used during platinum oxidation on anodic platinum (II) oxide properties in sensing solution pH. The straightforward approach used in this work for fabricating Pt/PtO microelectrode/nanoelectrode pH sensors by direct oxidation can ease real-time pH measurement in complex aqueous environments
enmpa: An R package for ecological niche modeling using presence-absence data and generalized linear models
No full textHere, we present the new R package “enmpa,” which includes a range of tools for modeling ecological niches using presence-absence data via logistic generalized linear models. The package allows users to calibrate, select, project, and evaluate models using independent data. We have emphasized a comprehensive search for ideal predictor combinations, including linear, quadratic, and two-way interaction responses, to provide more detailed and robust model calibration processes. We demonstrate the use of the package with an example of a simulated pathogen and its niche. Since enmpa is designed specifically to work with presence-absence data, our tools are particularly useful for studies with data derived from a detection or non-detection sampling universe, such as pathogen testing results. enmpa can be downloaded from CRAN, and the source code is freely available on GitHub
John Spearman and John Brown: The Free State Identity and the Legacy of Unrest in Lawrence, KS in 1970
No full textSubmitted to the Department of History of the University of Kansas in partial fulfillment of the requirements for departmental honors.This thesis explores the connection between the prominent Free State identity within Lawrence, Kansas and the recognition and memorialization of the unrest in Lawrence in 1970. The Free State identity limited many white Lawrencians’ in their acknowledgement of racial injustices within the community, and in the modern day, the memory of the racial turmoil within Lawrence during 1970 is fading due to the lack of effort by city officials to properly rectify the memory. While much of the current historiography characterizes Lawrence’s unrest as an extension of national movements, domestic racial issues were predominant catalysts for all major instances of unrest within the year 1970. I argue that the racial origins of the unrest are a major component of the modern issue of memorialization, as the city of Lawrence is reluctant to embrace a darker chapter of their history that would contradict their proud Free State identity. This reluctance forces the families of Rick Dowdell and Nick Rice, two young men who were killed by police during the unrest, to act as advocates for memorialization and caretakers of the memory of 1970. To document this fifty year struggle, I analyzed a plethora of oral histories, personal correspondence, and prominent secondary materials, while conducting a number of original interviews. Ultimately, I hope this thesis serves to outline the events and the fight of the Dowdell and Rice families to preserve and protect the memory of those lost during racial turmoil in Lawrence, and provide fuel to their efforts to memorialize the deaths in their fight to present Lawrence’s true history
Photocarrier dynamics at the interface between WS2 and ozone-irradiated graphene (Dataset)
No full textThe Excel file contains all original experimental data.We investigate the photocarrier properties of heterostructures (HSs) formed by WS2 and ozone-irradiated graphene (OI-graphene), with a focus on the impact of ozone irradiation. Photoluminescence and Raman spectroscopy reveal a pronounced doping effect induced by ozone irradiation on the graphene layer. Transient absorption measurements demonstrate a substantial suppression of charge transfer efficiency across the interface in the presence of ozone molecules. Spatially resolved pump-probe measurements further show a significant reduction in the diffusion coefficient of photocarriers in WS2 on OI-graphene compared to that of individual WS2 monolayers. The slower diffusion suggests enhanced spatial separation of electrons and holes in the WS2 layer, induced by a built-in electric field at the interface. This effect arises from the combined influences of doping and dielectric property changes caused by ozone molecules. These findings highlight the critical influence of ozone irradiation on graphene and HS interfaces, offering valuable insights for the design of future graphene-based two-dimensional HSs
The Tampons Are Not Alright: Deconstructing Epistemologies of Menstruation in “Modern” America
No full textSubmitted to the Department of History of the University of Kansas in partial fulfillment of the requirements for departmental honorsAlthough tampons were in use for centuries, it was not until the twentieth century that big businesses focused on mass manufacturing, marketing, and design of tampons. Despite these efforts, tampons fluctuated in consumer usage in the United States. This project will explore how misogyny, cultural taboos, and government oversight created a paradigm in which menstrual products were not properly tested and vetted for consumer safety, helping to create the Toxic Shock Syndrome crisis of the 1980s. Moreover, due to the racism and classism pervasive within the corporate and advertising structures of the tampon industry, tampons were primarily marketed to young, white women, partially leading to the result that they made up the typical victim profile, compared to other demographic groups. This research will re-affirm previous work on and provide new insights into the varying marketing strategies of tampon companies, especially after the scandal of TSS, the ways women responded to the unsafety of tampons at various points in time, and public reactions to the tampon-related health scandals
Merchants in Shakespeare’s The Merchant of Venice: A Transactional Analysis
No full textShakespeare’s The Merchant of Venice is a play with multiple merchants engaged in multiple transactions with multiple motives. The key characters – Shylock, Antonio, Bassanio, Portia, Jessica, Lorenzo, Nerissa, Graziano, and the Duke – are involved in one sort of business dealing or another. Indeed, there are 10 specific transactions: one finance transaction; one international trade transaction; one gastronomic transaction; two inheritance transactions; three marriage transactions; and two legal entrepreneurship transactions. In these deals, commerce and love are almost indistinguishable, and justice and mercy clash. Thus, lawyers can analyze the drama from a transactional perspective, and spot issues they encounter, directly or by analogy, in everyday practice

Decoupling Defined: Four Theories and Four Illustrations from the Sino-American Trade War
No full textThis article seeks to bring clarity to a much used, yet ill-defined, term “decoupling.” The article explores the theory and practice of “decoupling” in the context of the Sino-American Trade War, which, launched in March 2018, shows no sign of a ceasefire. As to theory, this article argues that conceptually, “decoupling” takes (at least) four forms. There is efficiency, jurisprudential, security, and values decoupling. As to practice, this article shows these four theoretical typologies of decoupling are obvious today. This theory and practice are illustrated (respectively) with respect to labor-intensive industries, commercial transactions in rule-of-man jurisdictions or with military-related firms, or which undermine freedom of conscience. Amidst the present Trade War, the article counsels for an expectation of more four-pronged based decoupling
