The aim of the present study was to take a closer look into the evidence for a theory of prehistoric string manufacture, formulated by the British archaeologist Karen Hardy in the article Prehistoric string theory. How twisted fibers helped to shape the world (Hardy, 2008). A problem with the article, with the relevance and validity of the presented evidence as substance for the theory, was the mi

This study emerges from the rising concern that the now widespread faith in renewable energy systems—as a way to deal with the ecological crisis—may be unfounded. Drawing on inspiration from the global peasant movement Via Campesina and their hypothesis that small-scale agriculture is a strategy for “cooling down the Earth”, this study seeks to discuss the reasons for the widespread belief in rene

Sveriges transportpolitiska mål belyser vikten av hållbara resor. En nationell cykelstrategi är framtagen som en del i att uppnå det övergripande målet. Cykelplanering måste ske på ett tidigt stadium och vara med under hela planprocessen och bilen måste komma i andra hand i stadsplaneringen. En bra grund i planeringen är att försöka beskriva funktionen i ett differentierat cykelnät, en uppdelning The Swedish transport policy objectives show the importance of sustainable transportation. A national bicycle strategy is developed to help achieve the general objective regarding transportation. The bicycle must be included in the whole process with the car coming in second hand. Basic recommendations for cities are to arrange their bicycle network in at least two parts, a main cycle network and

Introduction: In recent years omni-channel retailing has been accepted and used by both physical and e-commerce retailers. In omni-channel retailing different channels are integrated. An effective and efficient distribution system is becoming more crucial. The core of the distribution system is warehousing that affects lead time and logistics cost. The main challenge is to handle large store reple

In this thesis I study the performances of artificial neural networks (ANNs) and three various ARCH-type models to predict weekly volatility of the Swedish (OMXS30), the British (FTSE100) and the Australian (S&P/ASX200) major stock indices. The three various ARCH-type models are the GARCH(1,1), the EGARCH(1,1) and the TGARCH(1,1). The purpose is to investigate if ANNs outperform the more tradi

This study aims to explore how middle-managers, within public homecare services, perceive that they are affected by organizational structures, such as economic model, room for maneuver and budget responsibility, and organizational cultures, such as goals and personal values, in their effort to work with a client-centered perspective. The study was carried out by five semi-structured interviews wit

The aim of this study was to examine how social work students reason upon their future employer within social work. The analysis was based on three issues; how social work students reason around employments within the public sector, how they reason about employments in privately owned companies as well as which elements is considered significant when social work students chose their future employe

Om den tilltalade inte har förstått innebörden av sin gärning och inte har kunnat anpassa sitt handlande därefter, anses personen vara otillräknelig. I de flesta andra rättsordningar innebär det att den tilltalade inte kan dömas för brott, men svensk rätt saknar ett krav på tillräknelighet sedan brottsbalken trädde i kraft 1965. Sverige intar en särställning genom att samtliga kan bli föremål för If the defendant has not understood the meaning of their act and has not been able to adapt their actions accordingly, the person is deemed legally non-imputable. In most other legal systems, this means that the defendant cannot be liable, but since the Criminal Code entered into force 1965, Swedish law lacks a demand for imputability. Sweden has a peculiar regulation on the matters and everyone c

2008 ändrades den svenska sjukförsäkringsprocessen till ett nytt system, rehabiliteringskedjan. Rehabiliteringskedjan är i lag fastslagna tidpunkter i sjukskrivningsprocessen, där den sjukskrivnes arbetsförmåga ska prövas mot olika bedömningsgrunder. Den första är mot sina ordinarie arbetsuppgifter, den andra mot vad ens arbetsgivare kan erbjuda och den tredje är mot ett arbete som anses vara normIn 2008 the system for the assessment process within the Swedish sickness benefit was changed, into the rehabilitation chain. Within the rehabilitation chain, there are different stages of assessing the individual’s capacity for work. The different stages of assessments are enforced by law. The first assessment examines if the individual has the work ability to work with his or her regular task as

Digitaliseringen har i stor utsträckning revolutionerat sättet som företagen gör affärer på. Det finns inte längre samma behov av fysiska platser för affärsverksamheter eftersom teknologin har skapat virtuella platser där företag kan sälja både varor och tjänster utan att överhuvudtaget sätta en fot i jurisdiktionen. Emellertid har reglerna om fast driftställe alltsedan 1920-talet präglats av att The digitalisation has largely revolutionized the way companies do business. There is no longer the same need for physical locations for businesses for the reason that technology has created virtual locations where companies can sell both goods and services without even setting foot in the jurisdiction. However, the rules on permanent establishment have, ever since the 1920’s, been characterized b

Self-determination theory utgår från att autonomi, att frivilligt kunna och vilja bestämma över sina handlingar och beteende, är ett grundläggande behov för psykologisk utveckling och välbefinnande. Autonomi förmodas även spela en avgörande roll i att främja inre motivation på arbetet. Denna studie anammar ett self-determination theory perspektiv och syftar till att kvantitativt undersöka relationSelf-determination theory posits that autonomy, the experience of acting from choice rather than from external pressure, is essential for psychological well-being and development. Additionally, autonomy is thought to have a crucial role in facilitating intrinsic motivation in the workplace. Adopting a self-determination theory perspective, this thesis aimed to quantitatively study the relationship

Increasing global interconnectivity, in terms of our economies, ecological systems and population dynamics, can reduce or amplify the risks posed by climate change. The ongoing Coronavirus 2019 crisis demonstrates how rapidly disasters and risks can cascade and escalate across countries to become a shared problem globally. Climate change impacts are increasingly being recognised not only as a nati

Förlust av biodiversitet är ett av de största globala miljöbetingade problemen idag. Arter står inför ökande och potentiellt synergistiska hot från markomvandling och överexploatering av naturresurser, från globala såväl som lokala socioekonomiska krafter. Populationerna av ryggradsdjur har mellan år 1970 och 2016 visat på en global genomsnittlig minskning på 68 procent. Större djur, s.k. megafaunThe critically endangered Sumatran rhinoceros (Dicerorhinus sumatrensis) has, due to previous hunting and habitat loss, diminished to a few non-viable and fragmented populations. Despite a relatively large amount of conservation efforts during the last 30 years, numbers are still declining. Accurate numbers today are unknown, since the species is rare. Information indicates that less than 100 indi

A Tale of Two Proteins: SepF2 and SepF3 You might have heard of antibiotic resistance, which is one of the biggest public health issues of our time. In addition to the measures that should be taken at all levels of society to combat this issue, research to identify new antimicrobial targets to alleviate the rapid emergence of antibiotic resistance has become crucial. Cell division proteins in bac

Snö, glaciärer och regn över bergsområden möjliggör dricksvatten för miljoner av människor och fungerar som vattenreservoar för hela ekosystem. Under rådande klimatförändringar har smältande glaciärer i Himalaya blivit ett känt hot mot framtida dricksvattenförsörjning, men glaciärerna är inte de enda processer som påverkar tillgången på vatten. För att ta beslut som säkrar framtida vattentillgänglIn the central Himalayas, water dynamics are expected to change due to multiple factors like climate change, hydro power development and shifting land use practices. This thesis looks at possible changes in water dynamics in Marsyandi river basin, Nepal, as well as causes to those changes and how they are perceived locally. Grounded in critical physical geography, the study uses mixed methods an

Objective. To compare the effects of a restrictive versus a liberal fluid prescription, on quality of life, physical capacity, thirst and hospital admissions, in patients who had improved from NYHA class (III-)IV CHF to a stable condition without clinical signs of significant fluid overload. Design. The present study is a randomised cross-over study. Seventy-four patients (mean age 70 +/- 10 years

BACKGROUND: Hypothermia may be accidental or therapeutic. Therapeutic hypothermia is increasingly used as treatment for various conditions, e.g., neuroprotection after cardiac arrest. Hypothermia leads to an impairment of the coagulation system, but the degree of impairment has been difficult to determine. Most studies have been performed on plasma instead of whole blood. We therefore evaluated wh
