Making and breaking promises: On the voluntary provision of public goods under cost uncertainty
Breaking promises might be easier if one faces unexpectedly high costs for keeping them. Inspired by the ‘pledge and review’ mechanisms of the Paris Agreement, we investigate the role of cost uncertainty for both initial non-binding pledges and the subsequent voluntary provision of public goods. Without a pledge review process, we find that cost uncertainty not only leads to rather conservative pl
The private solution trap in collective action problems across 34 nations
Collective action problems emerge when individual incentives and group interests are misaligned, as in the case of climate change. Individuals involved in these problems are generally considered to have two options: contribute toward public solutions such as global warming mitigation or free ride. However, many collective action problems today involve a third option of investing in a “private solu
Measurement of the associated production of a top-antitop-quark pair and a Higgs boson decaying into a bb¯ pair in pp collisions at √s=13 TeV using the ATLAS detector at the LHC
This paper reports the measurement of Higgs boson production in association with a tt¯ pair in the H→bb¯ decay channel. The analysis uses 140 fb-1 of 13 TeV proton–proton collision data collected with the ATLAS detector at the Large Hadron Collider. The final states with one or two electrons or muons are employed. An excess of events over the expected background is found with an observed (expected
Cyclin-dependent kinase 10 controls bone formation and is linked to human skeletal health
BACKGROUND/OBJECTIVE: Bone remodeling is a critical process for skeletal health, and its dysregulation can lead to diseases like osteoporosis. While several Cyclin-Dependent Kinases (CDKs) are known to regulate bone metabolism, the function of CDK10 remains uncharacterized in this context. Human mutations in CDK10 cause the Al Kaissi syndrome, which involves severe skeletal defects, suggesting a
Slowing down : Degrowth and the limits to urban mobility
Cities worldwide face immense challenges in transitioning to a sustainable future. While being structurally and politically bound to continuous growth, the striving for a constant increase in production and consumption puts enormous pressure on our planet and its ecosystems. Degrowth has been proposed as a pathway to solving this dilemma. Although scholarly attention to urban degrowth has expanded
CSR som strategi: Hur butiksanställda upplever företagets hållbarhetsarbete
Corporate Social Responsibility (CSR) has become more important for companies in recent years, both as a marketing tool and a way to demonstrate as well as to maintain the organization's social, economical and environmental sustainability. While many organizations talk about sustainability, it is unclear how well this information reaches their frontline employees working in the stores. This th
Studying vocal annoyance with self-steered sound synthesis
The ability to hold listeners’ attention and prevent habituation is a crucial design feature for both biological and human-made distress and alarm signals, but their intrusive nature also causes stress and annoyance. To investigate what makes vocalizations distracting and annoying, we developed Self-Steered Sound Synthesis—a new experimental paradigm for studying voice perception, in which untrain

An impulse radar measurement in NE Greenland
A snowmobile towed impulse radar measurement was used to produce detailed maps of ice-thickness in two areas, one on a local dome (the Hans Tausen ice cap), and one on an outlet glacier north thereof. A constant spatial sampling was achieved by using a device attached to the snowmobile's odometer. The bedrock reflection was automatically detected in the majority of the data, by using digital signa

Reconstruction of electrical resistivity tomography (ERT) data using different base measurements
Electrical resistivity tomography (ERT) is a widely used technique for imaging subsurface resistivity distributions, but conventional data acquisition strategies face trade-offs between resolution, efficiency, and data quality. Comprehensive datasets that maximize subsurface information are impractical to measure directly, motivating the development of ERT data reconstruction approaches that can g
Measurement of the W-boson mass and width with the ATLAS detector using proton–proton collisions at √s=7 TeV
Proton–proton collision data recorded by the ATLAS detector in 2011, at a centre-of-mass energy of 7 TeV, have been used for an improved determination of the W-boson mass and a first measurement of the W-boson width at the LHC. Recent fits to the proton parton distribution functions are incorporated in the measurement procedure and an improved statistical method is used to increase the measurement
Search for new particles in events with a hadronically decaying W or Z boson and large missing transverse momentum at s = 13 TeV using the ATLAS detector
A search is presented for new particles produced in proton-proton collisions at a centre-of-mass energy of 13 TeV that result in final states comprising a massive vector (W or Z) boson that decays hadronically and large missing transverse momentum. The data sample was collected with the ATLAS experiment at the Large Hadron Collider from 2015 to 2018 and corresponds to an integrated luminosity of 1
Search for supersymmetry using vector boson fusion signatures and missing transverse momentum in pp collisions at √s = 13 TeV with the ATLAS detector
This paper presents a search for supersymmetric particles in models with highly compressed mass spectra, in events consistent with being produced through vector boson fusion. The search uses 140 fb−1 of proton-proton collision data at s = 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. Events containing at least two jets with a large gap in pseudorapidity, large missing tran
The Disinformation Economy: Digital Markets of Influence, Conflict, and Polarization
The online information landscape is a site for contested ideas, but it is also a marketplace; under the platform economy, every engagement has monetary value. This setup encourages content creators to circulate the kinds of material most likely to capture attention, even if it is incendiary. Central to this business model are the algorithmic recommendation systems, which are designed to monetize a
Operation and performance of the ATLAS tile calorimeter in LHC Run 2
The ATLAS tile calorimeter (TileCal) is the hadronic sampling calorimeter covering the central region of the ATLAS detector at the Large Hadron Collider (LHC). This paper gives an overview of the calorimeter’s operation and performance during the years 2015–2018 (Run 2). In this period, ATLAS collected proton–proton collision data at a centre-of-mass energy of 13 TeV and the TileCal was 99.65% eff
Exploring flexible structures in 3D- printed bio-based materials for specific product applications
This master thesis investigates possibilities to use additive manufacturing in the form of Fused Fil- ament Fabrication (FFF) with the material Polylactic Acid, to replace polyurethane foams for less environmental impact. The mechanical properties of foam are difficult to mimic and there are few or no materials that are similar, hence the great challenge to replace it. The idea of using a flexible
Strength analysis of rebuilt windows in historical buildings by the FE-method
Maskin- och monteringshallen i Varvsstaden i Malmö är en del av det tidigare Kockums-området, som under 1900-talet var en av stadens viktigaste industrimiljöer. Här byggdes fartyg som exporterades över hela världen, och området kom att spela en central roll i Malmös industriella utveckling. Hallen uppfördes 1912 och är idag ett kulturhistoriskt värdefullt industriminne som bevaras inom ramen för oThe Machine and Assembly Hall in Varvsstaden (Malmö, Sweden) is a heritage industrial building currently being refurbished into office space. As part of the renovation, the historic cast-iron framed windows will be complemented by an inner insulating window installed approximately 500 mm inside the existing line, creating an air cavity and altering the mechanical loading conditions of the original
