Many flying animals, like birds feeding their young, make commuting flights between a central place and foraging areas in the surroundings. Such central place foraging (CPF) represents a special case of foraging theory. We use simple geometry and trigonometry to analyse CPF flight performance (a round-trip cycle of outward flight from the central place and inward flight back along the reverse trac

A shift in new venture creation can be observed from purely profit-oriented models to alternatives attempting to also answer social and environmental needs. Because of their nature, these alternatives face issues regarding their integration in traditional financial and business spheres. Shared Value Creation is a framework that attempts to analyse these ventures and those challenges. Blockchain te
Comparative-methodological perspectives on borderland inhabitation En seminarieserie av Borderland Working Group Dwelling, elsewhere är en serie digitala seminarier om gränser, gränsland och rörelser över Öresund och vidare ut i världen. Serien består av åtta tillfällen där vi undersöker rörelser och gränser, och hur de förhåller sig till varandra. Serien är arrangerad av William Kutz i samarbete

Public engagement in local environmental planning and decision-making is often advocated on various grounds, both instrumental and normative. Yet in developed countries in the context of renewable energy infrastructure deployment, place attachment, place identity and place-protective action continue to be implicated in public objection. We set out an interdisciplinary change readiness hypothesis o
Animal signals involved in sexual selection are often indicators of individual quality. The assumption that sexual characters such as breeding plumage may indicate immune state has rarely been tested in free-living migratory birds, particularly in relation to innate immunity. If sexual characters indeed reflect immune condition, then these could be used to evaluate individual quality. Melanin is a
The Summary for Urban Policymakers (SUP) initiative provides a distillation of the IPCC reports into accessible and targeted summaries that can help inform action at city and regional scales. Volume I in the series, What the Latest Physical Science of Climate Change Means for Cities, identified the ways in which human-induced climate change is affecting every region of the world, and the cities an
This master thesis examines disabled residents’ roles as citizens in a place branding process within the political framework of a place. This is in line with the resident approach in a political context within the research field of place branding. My contribution to the resident approach is a case study in the municipality of Borås, where I study the organized work of accessibility between citizen
AbstractThis research aims to investigate and compare how computers work on five different workstation setups of multiple or large screens and viewing distances (27-inch and 49-inch at 70 or 90 cm viewing distance) affect muscular load in neck/shoulders, working postures, and perceived exertions of non-presbyopic participants.

Vårt arbete syftar till att öka kunskapen om hur yttre miljöfaktorer påverkar hudsjukdom, speciellt eksem och med fokus på kontaktallergi. Kontaktallergi förekommer hos nästan 30% av den vuxna befolkningen. Det allergiska kontakteksemet kan ses var som helst på kroppen, ofta på händerna. Kliniskt kan man inte skilja eksem orsakat av inre faktorer, endogent eksem, och eksem orsakat av yttre faktoreThe work is focused on increasing our knowledge of the effect the environment has on the skin, and particularly with regard to contact allergy and allergic contact dermatitis. About 30% of the adult population has contact allergy. The allergic contact dermatitis can affect any part of the body but most often it affects the hands. Clinically it is impossible to differentiate a dermatitis caused by
Brain organoid technology has seen significant development in recent years. This self-organized, three-dimensional, organ-oriented brain tissue model can recapitulate the process of neurogenesis and consists of diverse cell types and cellular architecture. Transplanting brain organoids in vivo could be a potential tool from bench to clinical research and has been studied for many purposes. To inve

Place branders express a desire for their work to aid in addressing crises such as climate change through sustainable developments that assist with brand positioning, yet little is known about how place branding professionals manage tensions and contradictions that arise between sustainability and investment development. This paper qualitatively explores how place branders talk about ecological su
Nya medicinska framsteg har gett effektiva verktyg för att framgångsrikt behandla ischemisk stroke, men de flesta patienter kommer för sent för att dra nytta av behandlingen. Tidig strokedetektion och diagnostik är därför avgörande för att möjliggöra expansion av de effektiva behandlingarna till en större del av strokepatienterna. Det var frustrationen att ha tillgång till en effektiv behandling, Recent advances in stroke treatment has provided effective tools to successfully treat ischemic stroke, but most patient still arrive too late to benefit from treatment. Early stroke detection and diagnostics are therefore essential in modern stroke care to improve treatment outcome by enabling expansion of reperfusion treatment to a larger portion of stroke patients. It was the frustration of hav
Clusters of stem cells at the tip of each plant shoot give rise to all of its above-ground organs, effectively controlling the development and the physical shape of the plant. A core network of negative feedback between CLAVATA3 (CLV3) and WUSCHEL (WUS) regulate the stem cells existence and behaviour in Arabidopsis thaliana. Despite the close relationship of these genes, their expression domains a
Popular Abstract in Swedish Blommor använder färg och doft för att locka till sig pollinatörer. Hur använder sig svärmare av dessa olika signaler för att hitta blomman? För att få svar på denna fråga undersöktes två arter av svärmare, en dagaktiv, Macroglossum stellatarum, och en nattaktiv, Deilephila elpenor. Båda arterna har färgseende och den nattaktiva svärmaren kan skilja på olika färger äveFlowers use different cues to attract pollinators including colour and odour. How do hawkmoths use these cues to find the flowers? This question was investigated in two species of hawkmoth, the diurnal species, Macroglossum stellatarum, and the nocturnal species, Deilephila elpenor. Both species have colour vision and D. elpenor can discriminate colours under very dim light intensities. Both speci
