Reglering av AI: för lite för sent, eller för mycket för tidigt? : En rapport om generativ AI och den europeiska AI-förordningen

Vi befinner oss i en formativ period gällande AI-reglering där de beslut som tas kommer att ha stor påverkan för en väsentlig tid framåt, globalt, i Europa såväl som i Sverige. Syftet med den här rapporten är att analysera processen med framtagandet av den europeiska AI-förordningen, dvs. placera in AI-regleringsaspekter i ett bredare perspektiv. Det görs genom att belysa rättsliga utmaningar kopp

Cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy in patients with advanced ovarian cancer (OVHIPEC-1) : final survival analysis of a randomised, controlled, phase 3 trial

BACKGROUND: The OVHIPEC-1 trial previously showed that the addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery resulted in improved progression-free and overall survival compared with cytoreductive surgery alone at 4·7 years of follow-up in patients with stage III epithelial ovarian cancer who were ineligible for primary cytoreduction. We report the fina

Evaluation of the ACR/EULAR 2022 criteria for classification of ANCA-associated vasculitis in a population-based cohort from Sweden

ObjectiveTo evaluate the ACR/EULAR 2022 criteria for ANCA-associated vasculitides (AAV) classification and compare them with the European Medicines Agency (EMA) algorithm and with classification based only on ANCA serology.MethodsIn the analysis, 374 cases (47% female) were classified according to the EMA algorithm, ANCA serology and ACR/EULAR criteria. The agreement rate was calculated using the

Institutional Quality, Trust, and Stock Market Participation: Learning to Forget

We explore the relations among institutional quality, households’ level of trust, and stock market participation. We find that institutional quality has a significant impact on both trust and participation. The individual level of trust significantly affects participation, but trust plays a small role in the effect of institutional quality on participation. Further, we demonstrate that immigrants

Copy number variants are ovarian cancer risk alleles at known and novel risk loci

Background: Known risk alleles for epithelial ovarian cancer (EOC) account for approximately 40% of the heritability for EOC. Copy number variants (CNVs) have not been investigated as EOC risk alleles in a large population cohort. Methods: Single nucleotide polymorphism array data from 13071 EOC cases and 17306 controls of White European ancestry were used to identify CNVs associated with EOC risk

A search for an unexpected asymmetry in the production of e+μ− and e−μ+ pairs in proton–proton collisions recorded by the ATLAS detector at s=13 TeV

This search, a type not previously performed at ATLAS, uses a comparison of the production cross sections for e+μ− and e−μ+ pairs to constrain physics processes beyond the Standard Model. It uses 139fb−1 of proton–proton collision data recorded at s=13 TeV at the LHC. Targeting sources of new physics which prefer final states containing e+μ− to e−μ+, the search contains two broad signal regions wh

Semi-Crystalline and Amorphous Polyesters Derived from Biobased Tri-Aromatic Dicarboxylates and Containing Cleavable Acylhydrazone Units for Short-Loop Chemical Recycling

Recycling polymers by site-specific scission into short-chain oligomers/polymers, followed by recoupling these to form the original polymer presents an energetically more favorable shorter-loop chemical recycling in comparison to recycling into monomers. Here, we present the synthesis and polymerization of triaromatic diesters to prepare polyesters with acylhydrazone units as weak structural links

Closed-loop chemically recyclable aromatic polyesters using asymmetric dicarboxylates obtainable from lignocellulose

Utilizing building blocks derived from lignocellulose is an attractive strategy towards biobased aromatic polyesters. Here, we present the straightforward synthesis of three new asymmetric di-aromatic diester monomers by one-step reactions of lignin-derived hydroxybenzoates (methyl paraben, methyl vanillate and methyl syringate, respectively) with potentially sugar-based methyl 5-chloromethyl-2-fu

Commercializing clean technology innovations : The emergence of new business in an agency-structure perspective

Since the 1970s, environment and energy-related problems have moved to centre stage on many political, business and research agendas. The notion of sustainable development has emerged as the dominant global discourse to adapt societies and economies to novel modes of production and consumption in areas such as transport, energy, housing, agriculture and food. For such shifts, new technology and te

The influence of functional and relational proximity on business angel investments

Business angels are a vital source of capital for innovative start-up firms. However, many potentially attractive investment opportunities are rejected during the angel's decision-making process. Information asymmetry, risk and distrust in the relationship between the investor and the entrepreneur result in investment barriers. The concept of proximity has been proposed as a conceptual foundation

On the structure of the informal venture capital market in Sweden : Developing investment roles

This paper has two objectives: first, to estimate the size of informal venture capital market in Sweden, and second, to explore the heterogeneity of informal investing behaviour. Based on quantitative data on 278 informal venture capital investors and 422 investments, this paper provides an estimation of the size of the informal venture capital market in Sweden and an analysis of its structure by

Understanding medical aspects of violent crimes in Sweden’s region Skåne: a retrospective cross-sectional design of the ViCS project

Introduction: While there has been a reduction in specific homicide categories in Sweden, the last decade has witnessed an increase in the overall rate. The escalation is predominantly linked to heightened gun violence associated with criminal gangs. As a result, Sweden faces an extreme rate of shootings and firearm-related homicides, constituting one of the most severe instances across Europe. Ho

Guest editorial: Accounting and performance measurement in the age of rankings, quality assurance, accreditation, and excellence frameworks

Over the past three decades, numbers, particularly those that can be expressed in financial terms, have come to be presented as a form of truth. Today, numbers guide and govern us, and shape and influence who we are, or who we should try to become (Kurunmäki et al., 2016). A few decades ago, this quantifying movement was restricted to a few fields. Today, however, it appears as if no one can escap

Peacocks, penknives and power : On the implications of evolutionary psychology for strategic communication

This article conceptualizes evolutionary theory as a bridge between existing theorizing in strategic communication on the one hand, the mind sciences on the other. It discusses six core concepts of evolutionary psychology that have a bearing on strategic communication theory: a) the human as a highly flexible social species; b) the regulation of individually-minded vs. collectively-minded behavior
