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

Direct neuronal reprogramming, by which a neuron is formed via direct conversion from a somatic cell without going through a pluripotent intermediate stage, allows for the possibility of generating patient-derived neurons. A unique feature of these so-called induced neurons (iNs) is the potential to maintain aging and epigenetic signatures of the donor, which is critical given that many diseases o

Low carbon input due to increasing specialization, intensification and reduced use of bio-fertilizer, leads to soil organic carbon (SOC) decreases in arable land. This is an emerging problem in Europe in general, where 45% of the EU soils have low and declining SOC content. SOC losses from agricultural soils influence soil fertility, putting food security at risk, and contributes to greenhouse gas

Risk for criminal behavior (CB), alcohol use disorder (AUD), and drug abuse (DA) are known to be familial. We know less about their transmission across three generations. We examined 844,109 probands born in Sweden 1980–1990, their parents, aunts/uncles, and grandparents for registration in population-based registers for CB, AUD, and DA. Mean tetrachoric relative-proband correlations (95% CIs) wer

Hard X-ray photoelectron spectroscopy (HAXPES) has been used to study the bulk electronic structure of thin molecular films of the organic compounds 2,2′,7,7′-tetrakis (N,N’-di-p-methoxyphenyl-amine)-9,9’-spiro-bifluorene (spiro-OMeTAD), 4-(diethylamino)-benzaldehyde-1,1)-diphenyl-hydrazone (DEH) and poly(3-hexylthiophene) (P3HT). Molecular layers of these compounds are hole conducting, a property

It is increasingly acknowledged that climate change is influencing terrestrial ecosystems by increased drought and rainfall intensities. Soil microbes are key drivers of many processes in terrestrial systems and rely on water in soil pores to fulfill their life cycles and functions. However, little is known on how drought and rainfall fluctuations, which affect the composition and structure of mic

© 2018 The Author(s). Background: Administration of antimicrobials to food-producing animals is regarded as a major contributor to the overall emergence of resistance in bacteria worldwide. However, few data are available on global antimicrobial use and resistance (AMR) in livestock, especially from low- and middle-income countries. Methods: We conducted a structured survey of 91 small-scale pig f

The “Green Sahara” is a period when North Africa was characterized by vegetation cover and wetlands. To qualitatively identify the orbital-climatic causation of the Green Sahara regime, we performed dynamic vegetation model (LPJ-GUESS) simulations, driven by climate forcings from coupled general circulation model (EC-Earth) simulations for the mid-Holocene, in which the vegetation is prescribed to
