The relationship between public sentiment and stock price fluctuations during corporate crises has attracted increasing attention in recent years. This study investigates the influence of public sentiment on stock price movements during a corporate crisis by integrating natural language processing of social media data, time series analysis and machine learning predictive model. Sentiment classific
Tidigare forskning har visat på att sömn stärker minnen. Denna studie ämnade att utforska detta i en verklig situation genom att studera sömns effekt på vittnesmål. De 18 deltagarna fick se en video av en fiktiv misshandel och efter 12 timmar, där hälften av deltagarna var vakna under dagen och andra hälften av deltagarna sov under natten. De fick svara på ett minnestest om videon. Frågorna var inPrevious studies have shown that sleep strengthens memory. The current study has put this into a real-life context and study sleep’s effect on witness testimony. The 18 participants watched a video of a fictitious assault, and after a 12-hour delay, where half stayed awake during the day, and half slept during the night. They answered a questionnaire about the video, as a memory test. The question
Parents of children with disabilities may face higher labor-market penalties given the extra care and support required. Using Swedish administrative data, we focus on first-born children with Cerebral Palsy (CP) to estimate impacts on parental labor-market outcomes. We apply an event study approach to identify effects up to 10 years after the birth of the child. Our results show that employment an
Context. The bar pattern speed of the LMC has been computed based on data from Gaia DR3 using three different methods. One method suggested that the LMC might be hosting a bar that barely rotates, and is slightly counter-rotating with respect to the disc of the LMC, with a pattern speed of Ωp = −1.0 ± 0.5 km s−1 kpc−1. Aims. We aim to confirm that tidal interactions might prevent the bar hosted by
High-speed vertical In–Ga–As nanowire MOS field-effect transistor (MOSFET) measurements were analyzed through parametric layout models. Measurements from small and large transistors were used to fit dependencies on the number of gate fingers and the number of wires per finger. Extrapolations via intrinsic and parasitic elements reveal the optimal layout for peak frequency performance. To achieve a
How does new technology impact labor market outcomes? We address this question by examining the adoption of electricity in Sweden during the early 20th century. Leveraging detailed individual-level data that covers the entire labor market and exogenous variation in electricity access driven by proximity to hydro-power plants, we estimate the impact of electrification on individual labor market out
Background: Monitoring metabolites of tamoxifen, such as endoxifen, has been suggested as a strategy to ascertain therapeutic effect of tamoxifen therapy, but clinical guidelines are missing. Herein, we aim to investigate the outcome of endoxifen concentrations of low-dose tamoxifen, using change in mammographic breast density as a proxy for therapy response. Methods: In the randomized KARISMA-Tam
The interplay between angular momentum and particle number (which is the equivalent to the angular momentum in gauge space) is studied. The same technique that is used in the case of rotations in ordinary space can be used in gauge space for investigating the properties of individual quasiparticle levels and the total angular momentum of a nucleus. We study the isotopes of Dy and W, where a back-
The strategic role of communication practitioners has been discussedsince the 1970s. While it might not be surprising that managers andcoworkers view their roles as unclear, it is more surprising that commu-nication practitioners themselves also struggle with explaining theirstrategic roles and the value of their work. To elucidate the strategicwork of communication practitioners, we conducted a s
Background: We aimed to study the long-term effect of smoking on coronary atherosclerosis progression at the segmental level. Methods: Angiographic data (1989-2017) on current, former, and nonsmokers were collected from the Swedish Coronary Angiography and Angioplasty Registry. The Western Denmark Heart Registry was used to validate the results. Patients with clinically indicated angiography with
When it comes to random walk on the integers Z, the arguably first step of generalization beyond simple random walk is the class of one-sidedly continuous random walk, where the stepsize in only one direction is bounded by 1. Moreover, the time until state 0 is hit by left-continuous random walk on Z started at 1 has a direct connection to the total progeny in branching processes. In the analysis
The investigation of carbon monoxide (CO) adsorption on the unreconstructed Ir(100)-(1 × 1) surface under ultra-high vacuum (UHV) conditions is studied with scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), and high-resolution core-level spectroscopy (HRCLS). At a low coverage of 0.5 ML (monolayer), CO molecules adopt a previously documented c(2 × 2) structure, having CO
Changes in pupil size can lead to apparent gaze shifts in data recorded with video-based eye trackers in the absence of physical eye rotation. This is known as the pupil-size artifact (PSA). While the PSA is widely reported in desktop eye trackers, it is unknown whether and to what extent it occurs in head-mounted eye trackers. In this paper, we examined the effects of pupil size variations on eye
Environmental, social and governance (ESG) investing has become a site of struggle,around which a range of actors at multiple scales and in different legal, political andfinancial spheres are mobilising. We delve into four dynamics that characterise thisquickly changing landscape and propose a set of conceptual avenues to analysethem. Gramscian political economy, legal geographies and science and
In 1959, the politics of assimilation led to the creation of a set of municipally organised camps for Roma people in the Stockholm area. The camps were to function as controlled settlements of transition for Roma families awaiting proper homes. This paper focuses on one such camp – the Skarpnäck Camp – which existed longer than anticipated, to the point that its continued operation was criticised
A fundamentally crucial suggestion to rectify the fits to the high-resolution X-ray photoelectron spectroscopy (XPS) raw data for the S 2p core level published by Dirin et al. (Nano Lett. 2023, 23 (5), 1914–1923) is presented herein.
This study explores subnational population ageing across Denmark, Finland, Iceland, Norway, and Sweden by examining municipalities that hold record values in three ageing measures: the share of the population aged 65 and over, mean age, and the prospective old-age dependency ratio. The analysis covers 1986-2023 for Sweden, Finland and Norway, 1998-2023 for Iceland and 2008-2023 for Denmark. The an
Precarity is a common condition for most healthy people living in tropical countries and obviously even more so in patients with cancer. Numerous socioeconomic, cultural, and educational difficulties influence the outcome of cancer management: poverty, diminishing extended family support among communities, lack of reliable cancer registries, poor awareness even within the medical community, limite
Background: Early-life growth adversity is important to later-life health, but precision assessment in adulthood is challenging. We evaluated whether the difference between attained and genotype-predicted adult height (“height-GaP”) would associate with prospectively ascertained early-life growth adversity and later-life all-cause and cardiovascular mortality. Methods: Data were first analyzed fro
