Physical retailing vs. physical distancing–an empirical study of Swedish retail adaptations in the wake of Covid-19

The Covid-19 pandemic represented a crisis that was handled in very different ways by different retailers. The purpose of this comprehensive empirical study is to explore how Swedish retailers adapted their retail formats, activities and governance over the course of the pandemic. Three types of adaptations were observed: adaptations in the physical store environment, new services connected to the

A pro-2 group with full normal Hausdorff spectra

We construct a 2-generated pro-2 group with full normal Hausdorff spectrum [0, 1] [0,1], with respect to each of the four standard filtration series: the 2-power series, the lower 2-series, the Frattini series, and the dimension subgroup series. This answers a question of Klopsch and the second author, for the even prime case; the odd prime case was settled by the first author and Klopsch. Also, o

Dietary Supplements and Nutraceuticals under Investigation for COVID-19 Prevention and Treatment

Coronavirus disease 2019 (COVID-19) has caused global disruption and a significant loss of life. Existing treatments that can be repurposed as prophylactic and therapeutic agents may reduce the pandemic’s devastation. Emerging evidence of potential applications in other therapeutic contexts has led to the investigation of dietary supplements and nutraceuticals for COVID-19. Such products include v

Probing and improving coherence in Free-electron lasers

Free electron lasers or FELs, have transformed the way science has been done in the last decades by providing coherent, highly brilliant radiation at wavelengths not achievable with conventional lasers. Their most important characteristic, along side brightness, is their coherence, which allows users to perform experiments that rely on precise phase characteristics of the probing radiation.The FEL

Single-shot transverse coherence in seeded and unseeded free-electron lasers: A comparison

The advent of x-ray free-electron lasers (FELs) drastically enhanced the capabilities of several analytical techniques, for which the degree of transverse (spatial) coherence of the source is essential. FELs can be operated in self-amplified spontaneous emission (SASE) or seeded configurations, which rely on a qualitatively different initialization of the amplification process leading to light emi

Binary separation control in preparative gradient chromatography using iterative learning control

Purification of biopharmaceuticals has shifted toward continuous and integrated processes, in turn bringing along a need for monitoring and control to maintain a desired separation between the target pharmaceutical and any impurities it may carry. In this study, a cycle-to-cycle control of the retention volumes of two compounds in a chromatographic, ion exchange purification step was developed, al

Mary Wollstonecraft och revolutionen

Kort efter att hon bevittnat den franska revolutionens fasor i Paris reste den engelska filosofen och feministen Mary Wollstonecraft till ett sömnigt Skandinavien. Kontrasterna kunde inte ha varit större. Ändå var det just i Sverige som hennes sista, stora politiska fråga väcktes: Hur förändrar man ett samhälle? Lena Halldenius följer Wollstonecraft på hennes sista filosofiska resa.Bildningsboxen

An Evaluation of Serum IgE and Th2-Associated Interleukins in Children With Uncomplicated and Complicated Appendicitis

Background: The pathogenesis of appendicitis is not understood completely and establishing a correct diagnosis can be clinically challenging. Previous investigations have shown an association between a T helper cell (Th)2-mediated inflammatory response, for example immunoglobulin E (IgE)-mediated allergy, and a decreased risk of complicated appendicitis. The present study aimed to evaluate differe

Organizational resilience and internal branding: investigating the effects triggered by self-service technology

The majority of studies on internal brand equity examine its various dimensions and relationships between them. While prior research specifies organizational practices relevant for successful internal branding, the insights about the impact of essential organizational factors on internal brand equity are still limited.

Increasing impacts of extreme winter warming events on permafrost

Winter warming events (WWE) are abrupt and short-lasting (hours-to-days) events of extraordinarily warm weather occurring during wintertime, sometimes accompanied by rainfall (rain on snow events; ROS). Through direct heat transfer and changes in the snowpack properties, these events cause changes in the below-ground thermal regime that, in turn, controls a suite of ecosystem processes ranging fro

Att stödja tvärvetenskapliga doktoranders frigörelse från disciplinära föreställningar

Ambitiösa ideal om tvärvetenskap är välkänt svåra att omsätta i praktiken, delvis beroende på att de motarbetas av hur många universitet är strukturerade. Detta är ett problem för doktorander i tvärvetenskapliga projekt såväl som för deras handledare. Tvärvetenskapliga doktorander har precis som alla doktorander ett forskningsämne i vilket de förväntas utvecklas till självständiga forskare men ockAmbitious ideals about interdisciplinarity are notoriously difficult to put into practice, partly because they are counteracted by how many universities are organised. This is a problem for doctoral students in interdisciplinary projects as well as for their supervisors. Interdisciplinary doctoral students, like all doctoral students, have a research subject in which they are expected to develop i

The Problems of Inflation Targeting Originate in the Monetary Theory of Knut Wicksell

The theoretical foundation of inflation targeting was laid out by the Swedish economist Knut Wicksell (1851-1926) in his groundbreaking treatise, Interest and Prices, published originally in German in 1898. Here he proposed price stability as the rule for monetary policy. Today, inflation targeting is considered the best-practice approach to monetary policy across the world. It has contributed to

Wanted : a low-carbon and fair reset

A piece about a just transition to a low-carbon future (contribution to UNESCO Inclusive Policy Lab 'Think pieces' that explores emerging issues in inclusive policies as well as offering cutting edge solutions).

App-based COVID-19 syndromic surveillance and prediction of hospital admissions in COVID Symptom Study Sweden

The app-based COVID Symptom Study was launched in Sweden in April 2020 to contribute to real-time COVID-19 surveillance. We enrolled 143,531 study participants (≥18 years) who contributed 10.6 million daily symptom reports between April 29, 2020 and February 10, 2021. Here, we include data from 19,161 self-reported PCR tests to create a symptom-based model to estimate the individual probability of

Cerebrospinal fluid is a significant fluid source for anoxic cerebral oedema

Cerebral oedema develops after anoxic brain injury. In two models of asphyxial and asystolic cardiac arrest without resuscitation, we found that oedema develops shortly after anoxia secondary to terminal depolarizations and the abnormal entry of CSF. Oedema severity correlated with the availability of CSF with the age-dependent increase in CSF volume worsening the severity of oedema. Oedema was id

The Impact of Physical Distancing on the Evacuation of Crowds

One of the key implications of COVID-19 is the adoption of physical distancing provisions to minimise the risk of virus transmission. Physical distancing can have significant consequences on crowd movement both in normal conditions and during emergencies. The impact of physical distancing is discussed in this chapter by first presenting an overview of its implications on crowd dynamics and space u

Concept design of electric cruise and startability axles for long haul heavy vehicles to maximise driving range

Electrification of commercial heavy vehicles has led to the offer of different electric drive-based powertrain architectures, most of them with the adaptation of the diesel engine based architecture. Due to the limited driving range possible, optimal configuration of the powertrain becomes a vital task with the battery as the energy source, which also takes a significant portion of payload capacit
