Constructing simulation models can be a complex and time-consuming task, in particular if the models are constructed from scratch or if a general-purpose simulation modeling tool is used. In this paper, we propose a model construction framework, which aims to simplify the process of constructing discrete event simulation models for emergency medical service (EMS) policy analysis. The main building

The article presents a semantic theory suggesting that equivalence and polyvalence are closely connected phenomena. The connection between them is utilised by making equivalence the basis of an argument for polyvalence within semantics, or in other terms, for a stratified semantics encompassing two levels of description. This argument from equivalence lends new support to frameworks assuming a str

Concerns about water and energy security have enhanced the water–energy nexus studies. However, even being well explored, some crucial aspects lack further analyses, such as the historical background of the relationship between the resources. This kind of analysis provides an in-depth understanding of the current situation and future perspectives and must, therefore, be included in WEN investigati

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly

The Astropy Project supports and fosters the development of open-source and openly developed Python packages that provide commonly needed functionality to the astronomical community. A key element of the Astropy Project is the core package astropy, which serves as the foundation for more specialized projects and packages. In this article, we summarize key features in the core package as of the rec

Social policy developed as a research field and academic discipline to ensure protection from social risks in the era of emerging capitalism and industrialization. While welfare states have successfully increased their citizens’ wellbeing, they have also contributed to the ecological crisis, while the shared scientific understanding of exceeded planetary boundaries and worsening climate change sce

Over the last 7 years, a multidimensional crisis in Venezuela has resulted in massive emigration. Over 7 million have fled the country, with more than 2.4 million seeking to settle in Colombia. Of these, as of 2021, more than 1 million were undocumented, but the situation has started to change with the implementation of an ambitious migrant regularisation scheme. Regularisation promises access to

AimTo describe child health care nurses' experiences of teaching infant massage in parent groups.DesignThis was an exploratory-descriptive qualitative study based on individual interviews.MethodQualitative semi-structured interviews were conducted with child health care nurses (N = 9) according to the COREQ guidelines and analyzed with qualitative content analysis.ResultsFive categories were ident

Artiklarna i detta nummer bearbetar frågor om levbarhet, motstånd och hopp på olika sätt, utifrån olika disciplinära kontexter och med en bredd av material. Frågan som ställs handlar om vilka som anses ha liv värda att skydda, och vad som gör livet levbart för de som positioneras utanför det begripliga och därmed skyddsvärda och sörjbara. Vi förhåller oss här till Butlers analys och förslag att täThe articles in this issue address issues of livability, resistance and hope in different ways, from different disciplinary contexts and with a wide range of materials. The question posed is who is considered to have lives worth protecting, and what makes life liveable for those who are positioned outside the intelligible and thus worthy of protection and care. Here we relate to Butler's analysis

Evidence is lacking on how to understand the reasons for variations, both in prevalence of ADHD and ADHD medication prescribing patterns in children and adolescents, within Region Skåne. These variations are not in line with current national clinical guidelines and seem to have increased over time. This qualitative interview study illuminates pediatric psychiatrists' attitudes toward ADHD and thei

Compact dual-polarization doppler X-band weather radars (X-WRs) have recently gained attention in Scandinavia for sub-km and minute scale rainfall observations. This study develops a method for merging data from two X-WRs in Dalby and Helsingborg, southern Sweden (operated at five and one elevation angle levels, respectively) to improve the accuracy of rainfall observations. In total, 87 rainfall

Current technological change is rapid and far-reaching, more so than ever before in human history. It is transforming all dimensions of human life, leading to large-scale adaptation. Among the disruptive new technologies that are being introduced into society, social robots are distinguished by their hybrid existence between mere thing and mindful agent. They are physical machines capable of inter

Background: Informal caregivers may experience high levels burden. Prior to COVID-19, loneliness and social isolation, and especially the discordance between them, were recognized for rapid aging-related cognitive decline. The COVID-19 has significantly increased social isolation and loneliness in caregivers. Thus, we aimed to explore the variables that were associated with higher care burden amon

Large-scale gene sequencing studies for complex traits have the potential to identify causal genes with therapeutic implications. We performed gene-based association testing of blood lipid levels with rare (minor allele frequency < 1%) predicted damaging coding variation by using sequence data from >170,000 individuals from multiple ancestries: 97,493 European, 30,025 South Asian, 16,507 African,

Background: Neurofibrillary tangle pathology is thought to drive neurodegeneration in beta-amyloid positive (A+) cognitively normal (CN) individuals, i.e., preclinical Alzheimer’s disease (AD).However, in beta-amyloid negative (A-) CN, the contribution of tau pathology [primary age-related tauopathy (PART)] to neurodegeneration remains uncertain. We investigate the correlation between tau burden m
