Gender Perspective(S): Lessons From International Human Rights Law To Defend Against Pregnancy Related Prosecutions, Megan Osadzinski Jun 2026

Gender Perspective(S): Lessons From International Human Rights Law To Defend Against Pregnancy Related Prosecutions, Megan Osadzinski

Northwestern Journal of Human Rights

The criminalization of pregnancy outcomes—such as miscarriages, abortion, obstetric emergencies, and stillbirth—is a violation of fundamental human rights guarantees; including the right to a fair trial when read in conjunction with the right to equality and the right to health. This article outlines state obligations under international human rights law toward women charged in pregnancy prosecutions, translating them into national criminal defense strategies using a gender perspective. Using intersectional theory, this article calls for the use of a gender perspective to challenge such prosecutions as unlawful gender-based discrimination and a gendered violation of due process, using the case study of …

Visibility By Design: Communication Infrastructures, Mediation, And Knowledge Transfer On Neurodivergence In Institutional Contexts En [Ponencia] Iamcr 2026, Bárbara Mercedes Castillo Abdul Hadi, María Beltrán-Rodríguez, Luis M. Romero-Rodriguez

Congresos y Conferencias

The social visibility of neurodivergence has become an increasingly salient object of inquiry within communication studies, particularly in relation to public communication, institutional communication, and processes of educational and social inclusion. Previous research has addressed this phenomenon primarily from the perspectives of health communication and awareness-raising campaigns, with a strong focus on stigma reduction and the improvement of public knowledge about neurodevelopmental conditions. However, these approaches have paid comparatively less attention to how communication intervenes in the transfer of scientific knowledge into applied contexts—such as the design of inclusive educational environments—and to its role in articulating the relationship between institutional …

Journal of Electrochemistry

Molecular catalysts serve as ideal platforms for studying electrocatalytic reaction mechanisms. While current research mainly focuses on modulating central metals or surrounding ligands, the influence of molecular spatial configuration remains largely unexplored. Herein, we synthesized two cobalt complexes with similar ligand environments but distinct spatial geometries, a planar cobalt hexaazamacrocyclic complex (CoHAM) and a non-planar acyclic Co(phen)2Cl2, and evaluated their performance in CO2 reduction reaction (CO2RR). The planar CoHAM exhibited dramatically superior CO2RR performance compared to the non-planar Co(phen)2Cl2. Through a series of combined analyses using in-situ …

Li+/Na+ Hybrid Ion Conduction Mechanism In The Superionic Conductor Li3–XNaXZr2Si2Po12, Yi-Hong Wu, Xia Xie, Lei Zhu, Mu-Ran Yu, Guo-Tai Zhang, Jun-Chao Chen, Shu-Ying Sun, You-Wei Wang, Wei-Ping Tang

Journal of Electrochemistry

Hybrid ion conductors that transport multiple ionic conductive species provide a useful platform for understanding how mixed-ion transport governs ionic conductivity within a single phase. However, the controlled introduction of multiple mobile ions into solid-state electrolytes and a mechanistic understanding of their migration within the framework remain challenging. Herein, a skeleton-retained Li+↔Na+ cationic exchange was used to simultaneously induce Li+ and Na+ cations into the NASICON-type framework of Li3–xNaxZr2Si2PO12 (0 < x < 3). We show that the interpenetration of NaO6 and NaO8 coordination polyhedra significantly influences the ionic conductivity of hybrid ion conductors. Computational …

Distribution And Transport Of Lithium Ions At Interfaces Between Graphite And Carboxymethyl Celluloses, Zi-Jun Huang, Zhen-Ying Zheng, Hua-Wei Cao, Jian Wang, Qing-Feng Zhang, Sheng-Li Chen Jun 2026

Distribution And Transport Of Lithium Ions At Interfaces Between Graphite And Carboxymethyl Celluloses, Zi-Jun Huang, Zhen-Ying Zheng, Hua-Wei Cao, Jian Wang, Qing-Feng Zhang, Sheng-Li Chen

Journal of Electrochemistry

Carboxymethyl cellulose (CMC) is a water-processable binder widely used for graphite anodes. However, a microscopic understanding of why the identity of CMC counterions (Li+/Na+/K+) strongly affects electrode performance remains limited. Here, molecular dynamics (MD) simulations are used to track Li+ transport accessibility across electrolyte/CMC/graphite three-phase interfaces, comparing pure CMC-Li, CMC-Na, CMC-K, and mixed-counterion CMC binders. We find that CMC-Li sustains a continuous Li+ transport pathway from the electrolyte through the binder phase toward graphite. In contrast, in CMC-Na and CMC-K, Na+/K+ ions preferentially enrich at the graphite/binder interface, forming …

Review Of: Documents Of Brotherly Love, Dutch Mennonite Aid To Swiss Anabaptists, Volumes I, Ii, Iii—James M. Lowry, Sheldon Raber Jun 2026

Review Of: Documents Of Brotherly Love, Dutch Mennonite Aid To Swiss Anabaptists, Volumes I, Ii, Iii—James M. Lowry, Sheldon Raber

Journal of Amish and Plain Anabaptist Studies

This set of three volumes of documents adds greatly to the accessibility of important historical documents by and about the Anabaptists in the seventeenth and eighteenth centuries. Many original documents and correspondence from this time period were preserved, primarily in Amsterdam. However, since the original documents were written in German, Swiss, and Dutch, they were not easily consulted by English-speaking historians and specifically by American Mennonite historians. And even though most of the documents were inventoried in the late nineteenth century, they were only selectively consulted by historians of the twentieth century. Since this reviewer is not schooled in languages, …

Review Of: Old Order Mennonite Spirituality: Analysis Of Ascetical And Mystical Parallels In Medieval Monasticism And A Contemporary Anabaptist Community—Andrew C. Martin, David Gilland, Laura Kelly, Donald Martin Jun 2026

Review Of: Old Order Mennonite Spirituality: Analysis Of Ascetical And Mystical Parallels In Medieval Monasticism And A Contemporary Anabaptist Community—Andrew C. Martin, David Gilland, Laura Kelly, Donald Martin

Journal of Amish and Plain Anabaptist Studies

Andrew Carl Martin’s doctoral dissertation is a welcome addition to the ecclesiologically significant, yet surprisingly under-researched topic of the relationship between strands in medieval Catholicism, especially monasticism, and Anabaptism in its various manifestations. To go a step further, Martin’s research deals specifically with Benedictine spirituality as outlined by The Rule of St. Benedict and a previously underappreciated branch of its legacy as found among the Old Order Mennonites in North America. That we are dealing with an “Order” in both cases is no insignificant aspect of the argument, for Martin ably shows that, direct historical connections notwithstanding, Old Order Mennonites …

Using Amish Scribes’ Newspaper Letters To Portray The New Wilmington, Pa, Amish Settlement, Kristin Park Jun 2026

Using Amish Scribes’ Newspaper Letters To Portray The New Wilmington, Pa, Amish Settlement, Kristin Park

Journal of Amish and Plain Anabaptist Studies

In studying distinctive ethnoreligious communities, it is preferable to listen to and analyze the voices of members themselves. This paper interprets the professed values, activities, and priorities of an understudied, hybrid Andy Weaver / Old Order Amish settlement using Amish scribes’ letters to two Amish and one non-Amish newspaper. Quantitative and qualitative content analysis of the newspaper letters discovered dominant themes of emotional expression, illness and accidents, visits, weather, and work and compared their prevalence across the newspapers. Amish newspapers were more emotionally expressive and highlighted members’ illness and injury while the non-Amish newspaper primarily focused on visiting, weather, and …

Life Writing Knowledge And Narrative Medicine : Creating The Transnational Self, Alfred Hornung Jun 2026

Life Writing Knowledge And Narrative Medicine : Creating The Transnational Self, Alfred Hornung

SOROUD: The journal of Literacy Criticism

Poetry and narration are among the most distinctive expressions of lifewriting. Poetic and narrative representations of the self, often associated with discrimination and disease, have got a psychotherapeutic effect. Ideally, collaborating agents in life- writing and narrative would produce a kind of societal knowledge with a global dimension, transcending the individual selfawareness, creating thus a framework for a would-be social integration. This paper is concerned with Audre Lorde’s poetic and narrative report on breast cancer, preceding her years in Berlin as a visiting professor in the 1980s, when her own experience as a “black lesbian poet or feminist lover” testified …

Some Palestinian Autobiographies Or ‘Only Palestine Is Real, Jacqueline Jondot Jun 2026

Some Palestinian Autobiographies Or ‘Only Palestine Is Real, Jacqueline Jondot

SOROUD: The journal of Literacy Criticism

This paper addresses the issue of writing reality and history in the autobiographies of some Palestinian writers. These autobiographies well directly from memories which become in the hands of their writers the only viable sources to document the Palestinian history. The position of the exile allows for the making of that history. The argument here goes to make these auto/biographies/ testimonials the raison-d’etre and the embodiment of a real Palestine.

Characteristic Analysis Of Detection Profiles For Internal Moisture Content Of Asphalt Pavements Based On Ground Penetrating Radar, Yang Li, He Pingping, Liu Weizhen, Fu An

Journal of China & Foreign Highway

As a novel non-destructive testing method for roads, ground penetrating radar (GPR) can effectively prevent road water damage by regularly detecting the internal moisture condition of roads. However, when the moisture data of GPR are analyzed, the moisture conditions obtained by relying solely on the analysis of a single profile characteristic may be misjudged. To improve the accuracy and reliability of GPR in detecting the internal moisture content of pavements, focus was placed on the time-frequency domain analysis of GPR moisture content detection profiles in this paper. Simulation tests were conducted, and the influencing factors and results of moisture detection …
