Statistical semantics : Methods and applications

This book discusses the application of various statistical methods to texts, rather than numbers, in various fields in behavioral science. It proposes an approach where quantitative methods are applied to data whereas previously such data were analyzed only by qualitative research methods. To emphasize the quantitative aspects of semantics, and the possibilities of conducting scientific interferen

Hygro-thermo-mechanical modeling of partially saturated air-entrained concrete containing dissolved salt and exposed to freeze-thaw cycles

In cold regions, understanding the freeze-thaw behavior of air-entrained concrete is important for designing durable structures and assessing the remaining service life of existing structures. This study presents a hygro-thermo-mechanical multiphase model that describes the cyclic freeze-thaw behavior of partially saturated air-entrained concrete containing dissolved salt. An equilibrium and a non

Taking Seat

The sound work "Taking Seat" by Robert Willim, could be experienced from a specially designed ‘sound bench’ placed outside Skissernas Museum in Lund. Combining manipulations of words and field recordings the work reflects practices of sitting.What are the forces set in motion by sitting? What are the technologies and techniques of sitting?Anthropologists argue that we have been living in The Sitti

A process model for collaboration in circular oriented innovation

Circular oriented innovation commonly requires collaboration. Yet, to date, circular research lacks empirical investigation into collaborative processes. Collaborative processes are, however, highly researched within strategic management literature, thus offering valuable insights. The purpose of this paper is to investigate, identify and order the processes that companies undertake when designing

Payments by modelled results : A novel design for agri-environmental schemes

From a theoretical point of view, result-based agri-environmental payments are clearly preferable to action-based payments. However, they suffer from two major practical disadvantages: costs of measuring the results and payment uncertainty for the participating farmers. In this paper, we propose an alternative design to overcome these two disadvantages by means of modelling (instead of measuring)

Incidence and outcome of myocardial infarction treated with percutaneous coronary intervention during COVID-19 pandemic

Objective Most reports on the declining incidence of myocardial infarction (MI) during the COVID-19 have either been anecdotal, survey results or geographically limited to areas with lockdowns. We examined the incidence of MI during the COVID-19 pandemic in Sweden, which has remained an open society with a different public health approach fighting COVID-19. Methods We assessed the incidence rate (

Do value-attitude-behavior and personality affect sustainability crowdfunding initiatives?

Crowdfunding is an innovative financial measure that is increasingly important in supporting sustainability initiatives. However, little research-based theory has been devoted to crowdfunding in light of the Sustainable Development Goals (SDGs). To bridge this gap, this study utilizes theories of value-attitude-behavior (VAB) model and personality to investigate Korean consumer crowdfunding behavi

Imaging in gynecological disease (20) : clinical and ultrasound characteristics of adnexal torsion

Objectives: To describe the clinical and ultrasound characteristics of adnexal torsion. Methods: This was a retrospective study. From the operative records of the eight participating gynecological ultrasound centers, we identified patients with a surgically confirmed diagnosis of adnexal torsion, defined as surgical evidence of ovarian pedicle, paraovarian cyst and/or Fallopian tube twisted on its

Field Delineation Using Medical Subject Headings (MeSH) : An alternative way to aggregate data in the web of science

Field delineation is important in bibliometrics. Particularly when measuring scientific performance, the demarcation of the area, to which a science actor belongs, is of the greatest importance. This paper present a method based on searches on Boolean combinations of medical subject headings (MeSH-terms) in a combined Web of Science (WoS) - Medline database. The construction of the MeSH area defin

Pion–kaon femtoscopy and the lifetime of the hadronic phase in Pb−Pb collisions at sNN=2.76 TeV

In this paper, the first femtoscopic analysis of pion–kaon correlations at the LHC is reported. The analysis was performed on the Pb–Pb collision data at sNN=2.76 TeV recorded with the ALICE detector. The non-identical particle correlations probe the spatio-temporal separation between sources of different particle species as well as the average source size of the emitting system. The sizes of the

Bolstering a transition for a more sustainable energy system : A transformative approach to evaluations of energy efficiency in buildings

A transition to a more sustainable energy system is called for, and to realise such a transition governments around the world have introduced various research programmes and policy instruments. In this paper, we elaborate on how the transition of the energy system could be reinforced through evaluation of research programmes and policy instruments, focusing on energy efficiency in buildings. We ar

Prospective isolation of radiation induced erythroid stress progenitors reveals unique transcriptomic and epigenetic signatures enabling increased erythroid output

Massive expansion of erythroid progenitor cells is essential for surviving anemic stress. Research towards understanding this critical process, referred to as stress-erythropoiesis, has been hampered due to the lack of specific marker-combinations enabling analysis of the distinct stress-progenitor cells capable of providing radioprotection and enhanced red blood cell production. Here we present a

The association between sociodemographic characteristics and dementia in patients with atrial fibrillation

Objectives: Association between socio-demographic factors and dementia risk is studied in general but not for atrial fibrillation (AF) patients. Methods: We studied AF patients ≥ 45 years in Sweden 1998–2012 (n = 537,513) using the Total Population Register for socio-demographic factors, the Swedish Cause of Death Register, and the National Patient Register (NPR) for incident dementia. Cox regress

Future of nuclear fission theory

There has been much recent interest in nuclear fission, due in part to a new appreciation of its relevance to astrophysics, stability of superheavy elements, and fundamental theory of neutrino interactions. At the same time, there have been important developments on a conceptual and computational level for the theory. The promising new theoretical avenues were the subject of a workshop held at the

Evaluation of engine efficiency, emissions and load range of a PPC concept engine, with higher octane and alkylate gasoline

Gasoline Compression Ignition research has shown that it can provide diesel like engine efficiency while maintaining gasoline like exhaust emissions. While research has shown that lower octane fuels might be good for that, they are also not available now. A good compromise for that would be the use of higher octane gasoline which is available in most places. For this study, experiments were perfor

Neoarchean large igneous provinces on the Kaapvaal Craton in southern Africa re-define the formation of the Ventersdorp Supergroup and its temporal equivalents

U-Pb geochronology on baddeleyite is a powerful technique that can be applied effectively to chronostratigraphy. In southern Africa, the Kaapvaal Craton hosts a well-preserved Mesoarchean to Paleoproterozoic geological record, including the Neoarchean Ventersdorp Supergroup. It overlies the Witwatersrand Supergroup and its world-class gold deposits. The Ventersdorp Supergroup comprises the Klipriv

Resilience in Virtual Teams : Developing the Capacity to Bounce Back

Resilience, or the capacity to bounce back from adversity strengthened and more resourceful, can be considered an important quality of virtual teams in the contemporary working world. A team is the basic organizational unit many modern firms are composed of—and, the virtual ones are those conducting teamwork over distance using a combination of telecommunications and information technologies to ac
