Starlings show considerable variation in egg mass among clutches. Mean clutch egg mass was highly repeatable for females, but few characteristics of females were found to relate to egg mass. Egg mass related weakly to female age, but female age only explained a small part of the variation. Hatchling mass was strongly correlated with egg mass, but body mass at 14 d of age was unrelated to egg mass.
In southern Sweden, the starling (Sturnus vulgaris) has a variable mating system with some males mating monogamously and others attracting several females. Mating status affected the reproductive success of females: monogamous and primary females laid larger clutches and fledged more and heavier young than secondary females. This pattern was explained by female competition for male help, with the
North Middle Sweden took part in a pilot “Regions in Industrial Transition”, launched by the European Commission to test new approaches to dealing with industrial transition. By focusing on specific challenges related to industrial transition, the pilot sought to develop new tools for regions and cities.
Discovered more than 40 years ago, microplastics have become a major environmental issue. With increasing global plastic production, microplastics are of growing concern. Landfills have been pinpointed as primary sources of microplastics to surface waters and they have, in fact, been identified and quantified as such. Due to their small size, different polymers and interfering non-plastic material
This article focuses on the role of lay health promoters in the Lindängen initiative, a community-based participatory research (CBPR) programme for health promotion that started 2016 in a low-income neighbourhood in the outskirts of Malmö, southern Sweden. The programme aimed to support equitable health and develop an innovative model for community health promotion. The purpose of this article is
Both in the social and natural sciences, methodologies have been developed to deal with relatively stable conditions, where findings can be validated based on past experiences. At a time when both social and natural phenomena are rapidly changing, new approaches are urgently needed to produce knowledge for systemic change, inform high-stakes decisions, and enable sustainability transitions in the
I Sverige kom det första undantaget från turordningsreglerna 1994 med syftet att upprätthålla balansen mellan arbetstagarnas trygghet och verksamheternas behov av flexibilitet. Sedan 2001 är undantaget i turordningsreglerna begränsat till två personer och gäller för företag med högst tio anställda. År 2020 är tvåundantaget återigen uppe för diskussion om ändring i och med betänkandet SOU 2020:30, In Sweden the first exception concerning turn rules was accepted in 1994 with the purpose to maintain the balance between employment protection and the companies need for flexibility. Since 2001 the exception concerning turn rules is limited to two employees for organisations with at most ten employees. In the year of 2020 the exception within the turn rules is up for discussion once again hence t
A fundamental precept of geochemistry is that arsenate coordinates at mineral surfaces in a predominately bridging-bidentate fashion. We show that this is incorrect for the model system, arsenate adsorbed at the surface of goethite (alpha-FeOOH), using a combination of XRD, EXAFS, and IR spectroscopic results. We report the crystal structure of pentaamminecobalt(III) arsenate, which consists of mo
This research examines the impact of digitalization on Sales and Operations Planning (S&OP) and its broader influence on supply chain performance. By adopting digital technologies, companies can streamline decision-making processes, reduce manual efforts, and enhance operational efficiency. The study aims to address the insufficient understanding of how the integration of digital technologies
The practice of product destruction, whereby retailers or manufacturers dispose of viable consumer products such as unsold goods or customer returns, is an extreme expression of the linearity of our current production-consumption system. This qualitative exploratory study aims to uncover why companies engage in this highly unsustainable and resource-inefficient behaviour and to explore the potenti
Background: Head computed tomography (CT) is a guideline recommended method to predict functional outcome after cardiac arrest (CA), but standardized criteria for evaluation are lacking. To date, no prospective trial has systematically validated methods for diagnosing hypoxic-ischaemic encephalopathy (HIE) on CT after CA. We present a protocol for validation of pre-specified radiological criteria
User grouping based on geographic location in fifth generation (5G) New Radio (NR) systems has several applications that can significantly improve network performance, user experience, and service delivery. We demonstrate how Sounding Reference Signals channel fingerprints can be used for dynamic user grouping in a 5G NR commercial deployment based on outdoor positions and heading direction employ
Gadolinium-148 is one of the radionuclides of most concern that will be produced in the tungsten target of the European Spallation Source (ESS), as a by-product of the spallation reaction used by the facility to produce neutrons. Since 148Gd a pure alpha emitter, it is both very radiotoxic and difficult to measure. With its half-life of 75 years, it will remain in the environment for a long time i
Sweden is actively seeking to scale up repair activities as part of its strategy to reduce waste, transition to a circular economy, and achieve zero net emissions by 2045. In the last couple of years, several new policies to promote consumer repairs have been adopted or proposed in Sweden. However, very little is known about the socio-cultural factors that shape people's decision to repair their p
Extending the lifetime of products is seen as a key objective for realising the vision of a Circular Economy. One way to increase the lifespan of products is to enable more repair activities. However, consumers encounter a variety of barriers for repairs, prompting public authorities in Europe and the US to adopt or propose policies in support of consumer repairs. Sweden has recently adopted a cir
I denna rapport redovisas populationstrender för 178 svenska fågelarter för åren 1975–2013. Fåglarna har räknats på vintern och på sommaren enligt strikt standardiserade metoder. Sommar- respektive vinterpunktrutter har räknats sedan 1975, i huvudsak i södra Sverige. Standardrutterna räknas också på sommaren (sedan 1996) men täcker hela Sverige. Vintern 2012/2013 räknades 130 000 fåglar av 128 artWe present the results of the Swedish Bird Survey, run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency. The results for 2013 include data from 580 winter point count routes in 2012/2013 (38th winter), of which 295 were carried out during the Christmas/New Year count and 273 summer point count routes (39th
BackgroundGraft-contaminating tumor cells correlate with inferior outcome in high-risk neuroblastoma patients undergoing hematopoietic stem cell transplantation and can contribute to relapse. Motivated by the potential therapeutic benefit of tumor cell removal as well as the high prognostic and diagnostic value of isolated circulating tumor cells from stem cell grafts, we established a label-free
