Agricultural intensification is one of the main causes for the current biodiversity crisis. While reversing habitat loss on agricultural land is challenging, increasing the farmland configurational heterogeneity (higher field border density) and farmland compositional heterogeneity (higher crop diversity) has been proposed to counteract some habitat loss. Here, we tested whether increased farmland

Pituitary adenylate cyclase-activating peptide (PACAP) is a neuropeptide implicated in a wide range of functions, such as nociception and in primary headaches. Regarding its localization, PACAP has been observed in the sensory trigeminal ganglion (TG), in the parasympathetic sphenopalatine (SPG) and otic ganglia (OTG), and in the brainstem trigeminocervical complex. Immunohistochemistry has shown

Den här avhandlingen undersöker staters interaktion som en social läroprocess, i syfte att förstå hur stater lär sig om miljönormer. Detta sker genom en konstruktivistisk ansats och mer specifikt ett roll-teoretiskt perspektiv, där en roll förstås som statens repertoar av beteende, jämsides dess funktion i en social interaktionskontext. Rollen formas av ego- och alterförväntningar, det vill säga bThis study investigates state interaction as a social learning process, where the ultimate aim is to enhance an understanding on how states learn of environmental norms. An entry into the domain on such learning processes is offered through a Constructivist approach and more specifically through the employment of a role theoretical perspective; a role here is signified as a state's repertory of be

Background: Autoimmune (type 1) diabetes (T1D) is a frequent chronic disease in children and adolescents globally. Gestational enterovirus (EV) infections have been associated with an increased risk for T1D in the offspring. We test the hypothesis that EV infections during the first trimester were associated with beta cell autoantibodies in mothers of children who developed islet autoantibodies be

The aim of this dissertation is to analyse value creation in a rural tourism development project. In order to analyse value creation, I investigate how participants of a rural tourism development project define and understand uniqueness of that particular rural area as a lever to developing a touristic offer. The empirical research question guiding this work is: How do participants of a rural tour

A search for doubly charged Higgs bosons with pairs of prompt, isolated, highly energetic leptons with the same electric charge is presented. The search uses a proton–proton collision data sample at a centre-of-mass energy of 13 TeV corresponding to 36.1 fb - 1 of integrated luminosity recorded in 2015 and 2016 by the ATLAS detector at the LHC. This analysis focuses on the decays H± ±→ e±e±, H± ±→

The purpose of this article is to contribute to the discussion concerning the present position and future directions of strategic communication by look- ing into the past and offering some proposals and a vision of how to develop and advance the field further. Research in strategic communication has mostly focused on communication professionals working in commu- nication departments or agencies as

A search is conducted for new resonances decaying into a W W or W Z boson pair, where one W boson decays leptonically and the other W or Z boson decays hadronically. It is based on proton-proton collision data with an integrated luminosity of 36.1 fb−1 collected with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of s=13 TeV in 2015 and 2016. The search is sensitive to

This study highlights the importance of different protein sources in the diet of Early and Middle Mesolithic humans in southern Scandinavia, and illustrates variation and change in protein consumption patterns during the Early Holocene. By combining previously published stable isotope data with new analyses of human and animal bone remains, a Bayesian mixing model was used to reveal that fishing w

Sexual conflict is a pervasive evolutionary force that can reduce female fitness. Experimental evolution studies in the laboratory might overestimate the importance of sexual conflict because the ecological conditions in such settings typically include only a single species. Here, we experimentally manipulated conspecific male density (high or low) and species composition (sympatric or allopatric)

This article tries to clarify whether negative charity appeals (i.e., advertisements emphasizing the bad consequences of not helping) or positive charity appeals (i.e., advertisements emphasizing the good consequences of helping) are more effective. Previous literature does not provide a single answer to this question and we suggest that one contributing reason for this is that different studies h

We used classical and extended adoption designs in Swedish registries to disentangle genetic and rearing-environment influences on the intergenerational transmission of divorce. In classical adoption analyses, adoptees (n = 19,715) resembled their biological parents, rather than their adoptive parents, in their history of divorce. In extended adoption analyses, offspring (n = 82,698) resembled the

Att vetenskapsteori och metodlära hänger ihop är utgångspunkten för denna bok. På ett unikt sätt kombinerar den vetenskapsteori med en grundläggande genomgång av olika typer av psykologisk forskningsmetodik. Med hjälp av konkreta exempel, tillämpade på psykologins ämnesområde, levandegörs vetenskapsteoretiska frågeställningar och abstrakta metodbegrepp.Boken ger en bred belysning av traditionell o

Formalization, understood as gaining legal status to develop their businesses, is the mainstream policy to regulate the work of street vendors in most cities in the world. However, formalization policies are criticized by different scholars, and many vendors go back to the streets after formalization despite government efforts. To contribute to this long-standing debate, this chapter explores the

Business owners play an important role in driving regional economic growth, and policy-makers seek to attract and retain such entrepreneurs by most means available. This paper analyses migration patterns, the factors that influence the propensity to move and assesses the relationship between firm performance and individual migration both before and after the move. The results show that (1) known e

Context: The biological mechanism for the association between sleep duration and incident diabetes mellitus (DM) is unclear. Sleep duration and Caspase-8, a marker of apoptotic activity, have both been implicated in beta cell function.Objective: To investigate the associations between sleep duration and plasma Caspase-8, and incident DM, respectively.Design: Prospective cohort study.Setting: The M

OBJECTIVE: Although claims data are widely used in medical research, their ability to identify persons' health-related conditions has not been fully justified. We assessed the validity of claims-based algorithms (CBAs) for identifying people with common chronic conditions in a large population using annual health screening results as the gold standard.STUDY DESIGN AND SETTING: Using a longitudinal
