Large stocks of soil organic carbon (SOC) accumulated in the Northern Hemisphere permafrost regions may be vulnerable to climatic warming, but global estimates of SOC distribution and magnitude in permafrost regions still have large uncertainties. Based on multiple high-resolution environmental variables and a compiled soil sample dataset (>3000 soil profiles), we used machine-learning methods to
Honeybees are one of our most important insects, not only for their pollination services but also for their production of honey. Honey is the main food for honeybees, produced from collected nectars and transported to the hive. Humans have consumed this mysterious food and applied it since ancient times in traditional medicine around the world. In 2005 we discovered an unknown key to honeybees’ he
Over the past decades, the growing proliferation of international institutions governing the global environment has impelled institutional interplay as a result of functional and normative overlap across multiple regimes. This article synthesizes primary contributions made in research on institutional interplay over the past twenty years, with particular focus on publications with International En
The planet is presently undergoing dramatic changes caused by human activities. We are living in the era of the Anthropocene, where our activities directly affect all living organisms on Earth. Insects constitute a major part of the world’s biodiversity and currently, we see dwindling insect biomass but also outbreaks of certain populations. Most insects rely on chemical communication to locate fo
The aim was to describe food intake over time in children and adolescents, with respect to age and gender. The present study was a repeated cross-sectional study using self-reported data from a health questionnaire. Data were collected from the School Health Services in south-east Sweden from 44 297 students, 10, 13-14 and 16 years of age, 48 % girls and 52 % boys from 2009/2010 to 2015/2016. Repo
The PICT method (pollution-induced community tolerance) can be used to assess whether changes in soil microbial response are due to heavy metal toxicity or not. Microbial community tolerance baseline levels can, however, also change due to variations in soil physicochemical properties. Thirty soil samples (0–20 cm), with geochemical baseline concentrations (GBCs) of heavy metals and from five diff
Understanding the causes and limits of population divergence in phenotypic traits is a fundamental aim of evolutionary biology, with the potential to yield predictions of adaptation to environmental change. Reciprocal transplant experiments and the evaluation of optimality models suggest that local adaptation is common but not universal, and some studies suggest that trait divergence is highly con
The aim of this thesis was to develop and apply self-registered and observed measures of physical function in people with arthritis in the lower extremity. In Paper I, 181 subjects from the Swedish Knee Arthroplasty Register who were satisfied with their primary knee arthroplasty were studied. 44% of the medical records included reports of pain in the replaced knee at the same time as the patient
The thesis aims at deconstructing the sustainable tourism paradigm: can tourism be "a global strategy for sustainable development", as the tourist industry claims? And will developing countries in particular profit from tourism development?To most international organizations and institutions (from the World Wide Fund for Nature to The World Bank), tourism, if carefully managed, is a positive, sust
The aim of this work was to study the leaching of hazardous substances in additives and admixtures that are commonly contained in concrete. Time-dependent leaching has been analyzed for three types of metal containing concretes: with ordinary Portland cement (OPC), fly ash, and slag. The concretes had uniform leaching patterns, clearly above detection limits. The prolonged diffusion test of 1,700
Popular Abstract in Swedish Syftet med avhandlingsarbetet har varit att ge ökad kunskap om (1) psykosocial ohälsa i befolkningen, (2) prevalens och orsaker till psykosocial ohälsa bland patienter i primärvården, och (3) bland långtidssjukskrivna. Datainsamlingen inkluderar resultatet av en befolkningsenkät riktad till ett slumpmässigt urval av 13 000 personer (20-84 år), ett frågeformulär till samThe aim of the thesis is to contribute to knowledge of (1) psychosocial illness in the population, (2) the prevalence and nature of psychosocial illness encountered in primary health care, and (3) encountered among persons with long-term illness. The data collected include the results of a questionnaire given to a population-based sample of 13 000 persons (20-84 years), a questionnaire given to ge
The society depends on reliable and robust services provided by technical infrastructures for its function. The impact of large-scale outages due to the inherent vulnerabilities of technical infrastructures has been demonstrated, for example, by the power outage in the U.S. in 2003 and the power outages in Sweden due to the storms Gudrun in January 2005 and Per in January 2007. Two of the main app
This article examines the diffusion of the Balanced Scorecard (BSC) in Swedish municipalities. The point of departure in the article is that there is a gap in our understanding concerning the diffusion of new management tools. Over the last decade, research has largely been based on empirical evidence regarding early adopters. Furthermore, these studies have largely been based on case study eviden
A pulse of respiration is induced by rewetting dry soil. Here we study the microbial responses underlying this pulse of respiration when rewetting soil dried for 4-days or 1-year. In the 4-days dried soil, respiration increased to a maximum rate immediately upon rewetting after which it decreased exponentially. In the 1-year dried soil, respiration also increased immediately, but then remained hig
Background Point-of-care C-reactive protein (POCCRP) is a biomarker of inflammation that offers clinicians a rapid POC test to guide antibiotic prescribing decisions for acute cough and lower respiratory tract infections (LRTI). However, evidence that POCCRP is cost-effective is limited, particularly outside experimental settings. Aim To assess the cost-effectiveness of POCCRP as a diagnostic tool
This overview paper examines three areas crucial to understanding why, despite clear scientific evidence for the growing environmental impacts of tourism transport, there is large-scale inertia in structural transitions and a lack of political will to enact meaningful sustainable mobility policies. These include the importance of addressing socio-technical factors, barriers posed by “technology my
The aim of this article is to analyze how nurses respond to and act upon neoliberal transformations of work. The article identifies and explores those transformations considered by my informants, nurses working in public sector hospital wards, as central to changing conditions of work and experiences of work intensifications. It further analyzes nurses’ responses toward these transformations and l
Popular Abstract in Swedish Kol-kolinteraktioner utgör starka kemiska bindningar. Detta innebär att de är relativt svåra att både bryta och bilda. Föreliggande avhandling sammanfattar mekanistiska studier av två reaktioner, Stillereaktionen och Heckreaktionen, med hjälp av vilka kol-kolbindningar kan bildas. Ett vanligt förekommande sammanfattningsnamn för denna typ av reaktioner är korskopplingsrThe present thesis deals with various types of palladium(II) and platinum(II) complexes and their use in homogeneous catalysis. The focus has been devoted to mechanistic investigations concerning the Stille and Heck reactions and studies under both catalytic and stoichiometric conditions were conducted. As a stoichiometric probe for studying the transmetallation step in the Stille reaction the pl

Surrogacy is a practice that raises ethical concerns, and is even illegal in many countries. In Sweden, surrogacy is not explicitly illegal, but the practice is deemed unallowed in a looser sense. Prostitution however, or more specifically the purchase of sexual services, which raises many of the same concerns regarding women’s autonomy and objectification, is banned explicitly by Swedish law. The
