Demarketing tourism for sustainability : Degrowing tourism or moving the deckchairs on the titanic?

Demarketing is generally recognized as that aspect of marketing that aims at discouraging customers in general or a certain class of customers in particular on either a temporary or permanent basis and has been increasingly posited as a potential tool to degrow tourism and improve its overall sustainability, particularly as a result of so-called overtourism. The paper provides an overview of the v

Spermatogonia Loss Correlates with LAMA 1 Expression in Human Prepubertal Testes Stored for Fertility Preservation

Fertility preservation for male childhood cancer survivors not yet capable of producing mature spermatozoa, relies on experimental approaches such as testicular explant culture. Although the first steps in somatic maturation can be observed in human testicular explant cultures, germ cell depletion is a common obstacle. Hence, understanding the spermatogonial stem cell (SSC) niche environment and i

Calcium Signaling in T Cells Is Induced by Binding to Nickel-Chelating Lipids in Supported Lipid Bilayers

Supported lipid bilayers (SLBs) are one of the most common cell-membrane model systems to study cell-cell interactions. Nickel-chelating lipids are frequently used to functionalize the SLB with polyhistidine-tagged ligands. We show here that these lipids by themselves can induce calcium signaling in T cells, also when having protein ligands on the SLB. This is important to avoid “false” signaling

Theoretical and Experimental Aspects of Current and Future Research on NbO2 Thin Film Devices

The present research front of NbO2 based memory, energy generation, and storage thin film devices is reviewed. Sputtering plasmas contain NbO, NbO2, and NbO3 clusters, affecting nucleation and growth of NbO2, often leading to a formation of nanorods and nanoslices. NbO2 (I41/a) undergoes the Mott topological transition at 1081 K to rutile (P42/mnm), yielding changes in the electronic structure, whThe present research front of NbO2 based memory, energy generation, and storage thin film devices is reviewed.

Sharing archaeological knowledge : The Interactive Reporting System

This study describes the development of a digital reporting system designed to provide archaeologists with a dynamic and interactive 3D web platform that can be used for describing in great detail records and activities undertaken across a multi-year field investigation campaign. The system was used to compose the archaeological report of a multi-year investigation and employed during the pandemic

Morbidity, risk of cancer and mortality in 3645 HFE mutations carriers

Background & Aims: Mutations in the HFE gene can lead to hereditary haemochromatosis (HH) and have been suggested to increase the risk of extra-hepatic diseases, especially breast and colorectal cancer. Here we investigated long-term outcomes of Swedish patients with HFE mutations. Methods: We identified 3645 patients with a homozygous p.C282Y (62%) or a compound heterozygous p.C282Y/p.H63D (3

The accumulation rate of tau aggregates is higher in females and younger amyloid-positive subjects

The development of tau-PET allows paired helical filament tau pathology to be visualized in vivo. Increased knowledge about conditions affecting the rate of tau accumulation could guide the development of therapies halting the progression of Alzheimer's disease. However, the factors modifying the rate of tau accumulation over time in Alzheimer's disease are still largely unknown. Large-scale longi

Stage-specific links between plasma neurofilament light and imaging biomarkers of Alzheimer's disease

Neurofilament light (NfL) is a marker of neuroaxonal injury, a prominent feature of Alzheimer's disease. It remains uncertain, however, how it relates to amyloid and tau pathology or neurodegeneration across the Alzheimer's disease continuum. The aim of this study was to investigate how plasma NfL relates to amyloid and tau PET and MRI measures of brain atrophy in participants with and without cog

"What's the problem?"-Toward a framework for collective problem representation in emergency response management

Responding to today's often transboundary emergencies, frequently characterized by unclear root causes and indistinct responsibilities as well as multiple actors, will require that responding actors come together to meet societal needs and solve problems arising in relation to those needs. In collective problem solving, representing the problem is crucial, especially in emergency situations, where

Apocalyptic argumentation : Trump and ISIS

Vi lever i en apokalyptisk tid. Apokalyptisk argumentation till stor del outforskad. Artikeln presenterar en analysmodell i tre steg: upplevd ondska, tidens tecken och tillförlitlig auktoritet, inspirerad av Stephen O'Leary. Artikeln innehåller två analysexempel: USA:s förre president Donald Trump och den Islamiska staten. Båda bygger sin argumentation på en apokalyptisk världsbild.Our time is an apocalyptic time, but the argumentation in this apocalyptic time has hardly been studied by scholars of argumentation. This article shows how both Donald Trump and the jihadist warriors of ISIS appeal to an apocalyptic worldview in their argumentation. The three topos of evil, time and authority from Stephen O’Leary’s Arguing the Apocalypse are used in the analysis. Both Trump suppo
