Developmental and comparative studies of the ability to understand communicative intentions using object-choice tasks raise questions concerning the semiotic properties of the communicative signals, and the roles of rearing histories, language and familiarity. We adapted a study by Tomasello, Call, and Gluckman (1997), in which a “helper” indicated the location of a hidden reward to children of th
Forskningsfråga: Skiljer sig kapitalstrukturen mellan familjeföretag och icke-familjeföretag? Syfte: Studiens syfte är att undersöka om det finns en skillnad i kapitalstruktur mellan familjeföretag och icke-familjeföretag noterade på börsen i Sverige. Utöver det undersöks hur företagsspecifika variabler, som exempelvis storlek, bransch och lönsamhet, påverkar företagens skuldsättningsgrad. MetodResearch Question: Does the capital structure differ between family-owned and non-family-owned businesses? Purpose: The purpose of this study is to investigate whether there is a difference in capital structure between family-owned and non-family-owned companies listed on the Swedish stock market. Additionally, the study examines how firm-specific variables, such as size, industry, and profitabil
Purpose: Posterior fossa tumour surgery in children entails a high risk for severe speech and language impairments, but few studies have investigated the effect of the tumour on language prior to surgery. The current crosslinguistic study addresses this gap. We investigated the prevalence of preoperative word-finding difficulties, examined associations with medical and demographic characteristics,
During the last decade, an active line of research in proof complexity has been to study space complexity and time-space trade-offs for proofs. Besides being a natural complexity measure of intrinsic interest, space is also an important issue in SAT solving. For the polynomial calculus proof system, the only previously known space lower bound is for CNF formulas of unbounded width in [Alekhnovich
This thematic report addresses frameworks for innovation related public procurement. It focuses on four specific kinds of procurement, namely (1) direct innovation procurement, (2) catalytic innovation procurement, (3) functional regular procurement, and (4) Pre-Commercial Procurement (PCP). (1) – (3) are also called Innovation-Enhancing Procurement (IEP). The four different kinds of innovation re
We estimate that there will be 13·7 million new cases of childhood cancer globally between 2020 and 2050. At current levels of health system performance (including access and referral), 6·1 million (44·9%) of these children will be undiagnosed. Between 2020 and 2050, 11·1 million children will die from cancer if no additional investments are made to improve access to health-care services or childh
Art funds are gaining traction as an alternative asset class, yet investors must often weigh financial returns against ethical objectives such as promoting diversity in the art market. This bachelor’s thesis investigates how these two motives interact by asking: How do ethical and financial drivers shape individual investors’ willingness to allocate capital to art funds? A two-part online survey
Utvecklingen av autonoma fartyg (‘MASS’) innebär betydande utmaningar för det befintliga systemet för sjörättsligt ansvar. Culpabaserat ansvar och begreppet vårdslöshet är traditionellt uppbyggda kring bedömningen av mänskligt handlande, beslutsfattande och kontroll. Detta väcker frågor om huruvida vårdslöshet och culpa fortfarande är begreppsmässigt sammanhängande när operativa beslut fattas av aThe development of Maritime Autonomous Surface Ships (‘MASS’) presents significant challenges to the existing framework of maritime liability law. Fault-based liability and the concept of negligence are traditionally structured around the assessment of human conduct, decision-making and control. This raises the question of whether negligence and fault remain conceptually coherent where operational
The Greenland Ice Sheet (GrIS) is seeing an accelerated rate of ice melt, which increasingly contributes to global sea-level rise. Studies have reported a growing mass imbalance coinciding with a widespread retreat of the island’s glacial termini. The associated discharge of ice is driven by submarine melting and ice breaking off glacial fronts, a process known as calving. The rate at which calvin

Introduction: Several studies have addressed technical aspects of endovascular thrombectomy (EVT), but it is not well known how procedural factors contribute to technical success in routine healthcare. The aim was to explore factors associated with technically successful EVT on nationwide scale. Methods: We did an observational register-based study assessing factors associated with technical succe

The implementationflow graphs of the higher radix cores are presentedtogether with a description of how these cores afTect a pipelinedFFT implementation. It is shown that the mixed radix FFT ismore expensive than the ra
The environmental problems caused by human interventions, such as the consumption of non-renewable resources and the emission of greenhouse gases are well-recognised. Calls have been made for immediate measures to develop more sustainable society worldwide. Attention has also been devoted to the quest for sustainability within the field of chemistry. The concept of “green chemistry” is being intro
Popular Abstract in Swedish Svenska lägenhetshushåll genererar i snitt 2.8-3.4 kg matavfall per vecka. Allt fler svenska kommuner har under senare år valt att införa separat insamling och biologisk behandling av matavfall. Den främsta anledningen till detta var det miljömål som syftade till att 35 % av matavfallet från hushåll, restauranger och storkök enligt riksdagens miljömål skulle behandlas bAn increased understanding of the world’s limited resources and the negative environmental impacts connected to solid waste management has in recent years increased interest in separate collection and treatment of organic waste in many parts of the world. As an example, increased biological treatment of organic waste is an explicit goal within the Swedish national solid waste management strategy (
In this thesis, I attempted to achieve a better understanding of the nature of X-linked polymorphic loci using a female-limited X chromosome (FLX) experimental evolution in Drosophila melanogaster. I expected that expressing the evolved X chromosome will result in an increase in female fitness and a decrease in male fitness. I first investigated the effect of an experimentally evolved female-limit
Sociality in spiders has evolved independently multiple times, resulting in convergently evolved cooperative breeding and prey capture. In all social spiders, prey is captured by only a subset of group members and then shared with other, non-attacking group members. However, spiders' propensity to attack prey may differ among species due to species-specific trade-offs between risks, costs and bene
Aims: To explore the association between HbA1c and sural nerve function in a group of people with normal glucose tolerance, impaired glucose tolerance or Type 2 diabetes. Methods: We conducted a 10-year follow-up study in 87 out of an original 119 participants. At study commencement (2004), 64 men and 55 women (mean age 61.1 years) with normal glucose tolerance (n=39), impaired glucose tolerance (
Zooplankton have evolved several mechanisms to deal with environmental threats, such as ultraviolet radiation (UVR), and in order to identify strategies inherent to organisms exposed to different UVR environments, we here examine life-history traits of two lineages of Daphnia pulex. The lineages differed in the UVR dose they had received at their place of origin from extremely high UVR stress at h
The majority of patients with a distal radius fracture (DRF) are elderly, a group known to experience difficulties with new technology, partly due to a low level of digital literacy. At the beginning of the coronavirus disease 2019 pandemic, during the spring 2020, patients that underwent DRF surgery had regular follow-ups replaced by video calls from their surgeon and physiotherapist. Afterward,
The elliptic flow (v2) of D mesons from beauty-hadron decays (non-prompt D) was measured in midcentral (30–50%) Pb–Pb collisions at a centre-of-mass energy per nucleon pair sNN=5.02 TeV with the ALICE detector at the LHC. The D mesons were reconstructed at midrapidity (| y| < 0.8) from their hadronic decay D → K -π + , in the transverse momentum interval 2 < pT< 12 GeV/c. The result indicates a po
