Jay Winter's powerful 1998 study of the 'collective remembrance' of the Great War offers a major reassessment of one of the critical episodes in the cultural history of the twentieth century. Dr ...Winter looks anew at the culture of commemoration and the ways in which communities endeavoured to find collective solace after 1918. Taking issue with the prevailing 'modernist' interpretation of the European reaction to the appalling events of 1914–18, Dr Winter instead argues that what characterised that reaction was, rather, the attempt to interpret the Great War within traditional frames of reference. Tensions arose inevitably. Sites of Memory, Sites of Mourning is a profound and moving book of seminal importance for the attempt to understand the course of European history during the first half of the twentieth century.
Abstract
In this article, I make a case for the methodological value of fiction and feminist storytelling to writing practices in management studies as well as provide an example of how this might be ...done. The epistemological conditions of fiction stimulate feminist critique distinct from the possibilities of autoethnography; we can write with less fear, in new collaborative and beautiful ways, with an audience in mind. Fiction offers us the opportunity to conjure collective dreams, to imagine feminist futures—it allows us to tell stories that simultaneously capture and release us. In practicing this, I present a fictionalized narrative inspired by an experience I had as a first year PhD researcher at a business management conference. There is nothing special or unique about the story. It is made up of the mundane, and yet it is overflowing with thematic significance. The story touches upon the aesthetics of academia, a politics of care, gaslighting, heteronormative assumptions, sexualization, embodiment, and neoliberal feminism, demonstrating how a single interaction can be about very many other, contradicting and co‐productive, things. I offer it as a message of solidarity to those who, like me, may struggle to articulate what exactly just happened, but know in their bodies that it was not fair—that it did not feel right.
This is a masterful volume on remembrance and war in the twentieth century. Jay Winter locates the fascination with the subject of memory within a long-term trajectory that focuses on the Great War. ...Images, languages, and practices that appeared during and after the two world wars focused on the need to acknowledge the victims of war and shaped the ways in which future conflicts were imagined and remembered. At the core of the memory boom is an array of collective meditations on war and the victims of war, Winter says.The book begins by tracing the origins of contemporary interest in memory, then describes practices of remembrance that have linked history and memory, particularly in the first half of the twentieth century. The author also considers theaters of memoryfilm, television, museums, and war crimes trials in which the past is seen through public representations of memories. The book concludes with reflections on the significance of these practices for the cultural history of the twentieth century as a whole.
Parenting during the COVID-19 pandemic is highly challenging, with parents having to meet various demands simultaneously. An increase in adverse childhood experiences (ACEs) has been widely ...predicted, but empirical evidence is still scarce. This study aimed to (1) generate representative data on pandemic-related stress, parental stress, general stress, parental subjective and mental health, and the occurrence of ACEs; (2) identify risk factors for an increase in ACEs, and (3) provide qualitative data on parents’ experiences. A representative survey was conducted in Germany in August 2020 with 1024 parents of underage children (

age
= 41.70, 50.9% female). More than 50% of parents reported being stressed by social distancing and the closure of schools and childcare facilities. Parental stress increased significantly during the pandemic (
d
= 0.21). Subgroups of parents also reported very high levels of depressive symptoms (12.3%) and anxiety (9.7%). Up to one-third of the sample reported ACEs in the child’s lifetime. In this group, 29.1% reported an increase in children witnessing domestic violence during the pandemic, and 42.2% an increase verbal emotional abuse. These families were characterized by higher parental stress, job losses, and younger parent and child age. Positive aspects of the pandemic related primarily to personal or family life (e.g. slower pace of life, increase in family time). While some parents coped well, a particularly negative pattern was observed in a subgroup of families that experienced an increase in ACEs. Parental stress emerged as important target point for interventions addressing the negative sequelae of the pandemic.
Venous thromboembolism (VTE) is a common disease (~700 per 100 000) that is associated with significant risk of recurrence, chronic complications, and substantial mortality, with reported death rates ...of up to 40% at 10 years. The development of novel anticoagulants has revolutionized the treatment of acute VTE, while strategies for prevention and treatment of chronic complications still seek for such a landmark change. Impaired thrombus resolution is the common denominator behind VTE complications, which are postthrombotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension (CTEPH). PTS and CTEPH are associated with substantial morbidity and high healthcare expenses. While PTS occurs in up to 50% of patients after symptomatic deep vein thrombosis, only a small and poorly defined number of patients are diagnosed with CTEPH after pulmonary embolism. This review is a comprehensive summary of VTE-related chronic complications, their epidemiology, diagnosis, and treatment.
The description of quantized collective excitations stands as a landmark in the quantum theory of condensed matter. A prominent example occurs in conventional magnets, which support bosonic ...magnons-quantized harmonic fluctuations of the ordered spins. In striking contrast is the recent discovery that strongly spin-orbital-coupled magnets, such as α-RuCl
, may display a broad excitation continuum inconsistent with conventional magnons. Due to incomplete knowledge of the underlying interactions unraveling the nature of this continuum remains challenging. The most discussed explanation refers to a coherent continuum of fractional excitations analogous to the celebrated Kitaev spin liquid. Here, we present a more general scenario. We propose that the observed continuum represents incoherent excitations originating from strong magnetic anharmonicity that naturally occurs in such materials. This scenario fully explains the observed inelastic magnetic response of α-RuCl
and reveals the presence of nontrivial excitations in such materials extending well beyond the Kitaev state.

The Arabidopsis root has been the subject of intense research over the past decades. This research has led to significantly improved understanding of the molecular mechanisms underlying root ...development. Key insights into the specification of individual cell types, cell patterning, growth and differentiation, branching of the primary root, and responses of the root to the environment have been achieved. Transcription factors and plant hormones play key regulatory roles. Recently, mechanisms involving protein movement and the oscillation of gene expression have also been uncovered. Root gene regulatory networks controlling root development have been reconstructed from genome-wide profiling experiments, revealing novel molecular connections and models. Future refinement of these models will lead to a more complete description of the complex molecular interactions that give rise to a simple growing root.
Petroleum coke (PeC), a soft carbon, displays excellent performance at high current densities so that it can be considered as a very promising material for high performance lithium-ion capacitors ...(LICs). PeC-based LICs deliver a specific energy and power of 48 Wh kg−1 and 9 kW kg−1, respectively, upon charge–discharge tests carried out using a current density of 4.5 A g−1 (corresponding to 30 C). These values are outperforming those displayed by supercapacitors and lithium-ion batteries under the same condition, and such performance can be maintained for 50,000 cycles.
•Soft carbons can be successfully used for the realization of high performance LICs.•LIC containing soft carbon display high power and energy.•LIC containing display stable performance for 50,000 cycles.
A comprehensive analysis of the degradation mechanisms on the surface of commercial LiNi0.5Co0.2Mn0.3O2 electrodes is presented. Irregularly distributed particle cracking and the formation of a ...cathode electrolyte interphase on the surface of the active material were identified to be the main degradation mechanisms. The particle cracking originates from inhomogeneity of the composite electrode, leading to deviations in the local current density and the state of charge which results in overcharge conditions for particular LiNi0.5Co0.2Mn0.3O2 particles. Therein, the highly delithiated structure suffers from anisotropic stress due to repulsive interactions between adjacent layers and the formation of new phases which eventually cause particle cracking. The structural changes were confirmed by the presence of a spinel phase on the surface of the cracked particles. Furthermore, the migration of transition metal ions in the highly delithiated structure can facilitate their dissolution into the electrolyte. The investigation of the re-deposited transition metals reveals a predominant dissolution of manganese from the overcharged particles. In addition, electrochemical cycling of the LiNi0.5Co0.2Mn0.3O2 electrodes in laboratory cells show an increasing severity of the particle cracking at higher C-rates which can influence the thermal stability of the active material. Moreover, an increased electrolyte decomposition was observed for higher cut-off potentials.

The identification of RNAs that are not translated into proteins was an important breakthrough, defining the diversity of molecules involved in eukaryotic regulation of gene expression. These ...non-coding RNAs can be divided into two main classes according to their length: short non-coding RNAs, such as microRNAs (miRNAs), and long non-coding RNAs (lncRNAs). The lncRNAs in association with other molecules can coordinate several physiological processes and their dysfunction may impact in several pathologies, including cancer and infectious diseases. They can control the flux of genetic information, such as chromosome structure modulation, transcription, splicing, messenger RNA (mRNA) stability, mRNA availability, and post-translational modifications. Long non-coding RNAs present interaction domains for DNA, mRNAs, miRNAs, and proteins, depending on both sequence and secondary structure. The advent of new generation sequencing has provided evidences of putative lncRNAs existence; however, the analysis of transcriptomes for their functional characterization remains a challenge. Here, we review some important aspects of lncRNA biology, focusing on their role as regulatory elements in gene expression modulation during physiological and disease processes, with implications in host and pathogens physiology, and their role in immune response modulation.
