Agricultural output fluctuated worldwide after the emancipation of slaves. The usual explanation is that former slaveholders now lacked labor. This is not the full story: slaves were not just laborers but capital investments to support production. Using databases covering more than 40 years from Stellenbosch in the British Cape Colony, this study measures changes in output before and after emancip
Slutsatsen av denna undersökning är att Birger Gregersson has skrivit ett skickligt utformat, något pompöst officium som förmedlar en bild av Birgitta som ett helt och hållet universellt helgon och samtidigt en utsökt prydnad för sitt eget land. Nils Hermansson har å sin sida givit oss en Birgitta som i sitt liv och sin undervisning är en trogen dotter till Jungfru Maria och en kyrkolärare. Nils H
c-myc protooncogene positively regulates cell proliferation and overexpression of c-myc is found in many solid tumors and leukemias. In the present study we used the K562 human myeloid leukemia cell line as a model to study the functional interaction between c-Myc and p53. Using two different methods, we generated K562 transfectant cell lines with conditional expression of either c-Myc or p53. The
The human antimicrobial peptide LL-37 permeabilizes the plasma membrane of host cells, but LL-37-induced direct effects on mitochondrial membrane permeability and function has not been reported. Here, we demonstrate that LL-37 is rapidly (within 20 min) internalized by human osteoblast-like MG63 cells, and that the peptide co-localizes with MitoTracker arguing for accumulation in mitochondria. Sub
This article aims to provide a systemic instrument to evaluate the functioning of higher education systems. Despite systemic instruments have had a strong impact on the management of public policy systems in fields such as health and innovation, higher education has not been widely discussed in applying this type of instrument. Herein lies the main gap that we want to close. The ultimate purpose o
Background: Medical conditions related to alcohol use disorders (AUD) represent a substantial public health concern. However, only a subset of individuals with AUD develop these conditions and the extent to which genetic and environmental factors that are shared with AUD, versus those distinct from it, contribute to this progression has not yet been determined. Methods: Using data from Swedish nat
BACKGROUND: Some pesticides, used in large quantities in current agricultural practices all over Europe, are suspected of adverse effects on human reproductive health (breast and prostate cancers), through mechanisms of endocrine disruption and possible carcinogenic properties, as observed in agricultural settings. However, evidence on dietary pesticide exposure and breast cancer (BC) is lacking f
Climate can exert an effect on the strength of sexual selection, but empirical evidence is limited. Here, we tested whether climate predicts the geographic distribution and introgressive spread of sexually selected male color ornamentation across 114 populations of the common wall lizard, Podarcis muralis. Coloration was highly structured across the landscape and did not reflect genetic differenti
Ellenberg indicator values for plant species are widely used metrics in ecology, providing a proxy measure of environmental conditions, without direct measurements. They integrate environmental conditions over time since species will only persist where conditions are favourable. Ellenberg moisture (F) values summarise the hydrological environment experienced by plants. However, the relationship be
Although many studies on mental health have been conducted among various populations during the COVID-19 pandemic, few studies have focused on post-traumatic growth (PTG) in the general population. The current study aimed to explore whether perceived social support, personality, and coping strategies are associated with PTG in the COVID-19 pandemic period. The study also investigated whether copin
Recent pT-integrated cross-section measurements of the ground-state charm mesons and baryons, D0, D+, Ds+, Λc+, and Ξc0, are used to evaluate the charm fragmentation fractions and production cross section per unit of rapidity at midrapidity (|y|
Collaboration between academia and actors outside academia (AOAs) has been proclaimed as a way for society to confront challenges in different fields. This ‘participatory imperative’ is anchored in EU research policy. The paper explores the participatory imperative in contemporary Swedish aging research. Three kinds of motives for participatory research as a way to societal impact emerged in the s
In ordinary public rooms, such as classrooms and offices, an absorbent ceiling is the typical first acoustic action. This treatment provides a good acoustic baseline. However, an improvement of specific room acoustic parameters, operating for specific frequencies, can be needed. It has been seen that diffusing elements can be effective additional treatment. In order to choose the right design, pla
Objective: To evaluate the influence of implant and prosthetic components on peri-implant tissue health. A further aim was to evaluate peri-implant soft-tissue changes following surgical peri-implantitis treatment. Materials and methods: Group discussions based on two systematic reviews (SR) and one critical review (CR) addressed (i) the influence of implant material and surface characteristics on
The social restrictions during the covid-19 pandemic have challenged many aspects of preschool everyday life. Particularly vulnerable to these restrictions is the aspect of introducing new children to preschool, since preschool introduction constitutes a natural arena for establishment of preschool staff’s relationships with children and their parents. Based on analysis of open-ended survey data (
Today parents are faced with increasing expectations to attend to their young children’s learning and cognitive development. South Korea and Singapore are well-known for their competitive education systems and for consistently topping international student assessment tests. They also share an inflated private tuition industry, fuelled by the assumption that parents are compelled to invest substant
The Fukushima nuclear disaster posed food safety risks on an unprecedented scale in Japan. In its immediate aftermath, information on the scale and the extent of the contamination of the food chain was scarce. Facing an anxious public, the government was tasked with defining and ensuring food safety amidst uncertainty. Via three case studies spanning from 2011 to 2020, this article draws on risk c
