Crowdfunding has witnessed growing interest within academia in recent years, despite the underlying motivations for entrepreneur engagement in crowdfunding activities receiving little attention. The purpose of this study is to explore the motives that influence entrepreneurs when using crowdfunding and how these motives are related to each other. This will then provide a deeper understanding of ho
Sub-Saharan Africa suffers from land degradation, depletion of natural resources and rural poverty. In the Lake Victoria Basin, where large parts of the population are small scale farmers, people are facing such issues coupled with altered climatic conditions. The focus area of this study is the Mara region in northern Tanzania, situated on the eastern lakeshore. Mara has experienced a doubling of

The research is conducted by an abductive approach using theory and empirical data alternately. Both quantitative and qualitative methods have been adopted in order to see changes in customer behaviour as well as expla
Nerve fibres play an important role in the regulation of gastric emptying. The aims of this study were to clarify the distribution, projections and origin of neuronal type nitric oxide synthase (NOS)-, tyrosine hydroxylase (TH)-, vesicular acetylcholine transporter (VAchT)- and peptide-containing nerve fibres of the rat pyloric sphincter. Extrinsic and local denervations of the sphincter were perf
Background: The aim of this study was to explore the feasibility of using a technique based on artificial neural networks for quality assurance of image reporting. The networks were used to identify potentially suboptimal or erroneous interpretations of myocardial perfusion scintigrams (MPS). Methods: Reversible perfusion defects (ischaemia) in each of five myocardial regions, as interpreted by on
This paper presents a front-end architecture for fully integrated 60 GHz phased array receivers. It employs LO-path beamforming using a phase controlled phase-locked loop (PC-PLL). To demonstrate the architecture a circuit is implemented featuring a two stage low noise amplifier, two cascaded active mixers, and a PC-PLL. The receiver downconverts the 60 GHz signal in two steps, using LO signals fr
There is an ongoing discussion in information retrieval research regarding the merits of subject indexing with controlled vocabularies as opposed to relying on free-text descriptions. Earlier research has compared subject headings with other metadata, such as document titles or tables of contents, to determine the relative value of subject headings as subject access points in an information search
Stellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. In particular, hyperfine structure (hfs) data in the near-infrared region is lacking
BIM, byggnadsinformationsmodellering, är ett arbetssätt som blir allt vanligare. Det innebär att olika objekt bygger upp en övergripande 3D-modell där man kan finna mängder av information om dessa objekt. Ett objekt kan vara allt ifrån en bropelare till en elstolpe. Syftet med denna rapport är att utifrån Trafikverkets roll som beställare undersöka vilka för- och nackdelar det skulle innebära med BIM, Building Information Modeling, is an increasingly common way of working. This means that different objects build up an overall 3D-model where you can find lots of information about these objects. An object can be anything from a bridge pillar to an electric pole. The purpose of this report is to, based on the Swedish Transport Administrations’ as a client, investigate the advantages and disad
Introduction: This study attempts to optimize the choice of stationary phase for the separation of lignosulfonate lignin compounds using supercritical fluid chromatography coupled to mass spectrometry. Background: Lignin is a potential renewable source of phenolic compounds. Lignosulfonate lignins are produced during pulping processes producing very complex mixtures, which are challenging to anal
Ever since the dawn of internet, a new wave of fast-growing software companies has emerged. The M&A scholars have struggled to find appropriate valuation mechanisms for unprofitable companies with ultra-high revenue growth. To overcome the uncertain future, a contractual provision called earnout is often used. An earnout is a contractual provision in a M&A-deal that states the seller of th
Title: Mapping, development and optimization of internal logistics in a multi- stage production facility Authors: Nils Jönsson and Björn Hofbard Supervisors: Eva Berg, Department of Industrial Management and Logistics. Conny Andersson, Sandvik Background: In highly dynamic and competitive environments, supply chain management and logistics can create important advantages against competitors. Since
The noise, vibration and harshness (NVH) and body dynamic performance of automotive vehicles is highly dependent of the components included in the body structure and compartment, since they add mass, stiffness and damping to the overall structure. Today, the noise levels in the compartment are predicted using complex and detailed computational models during both early and late stages of the vehicl
Detta arbete undersöker processrättens roll på det migrationsrättsliga området, så som den kommer till uttryck genom ett antal migrationsprocessrättsliga särdrag. Centralt för undersökningen är hur avvägningen mellan de motstående intressena individens rättssäkerhet och processuell effektivitet har gjorts i migrationsprocessen. Den första särdraget som behandlas är den på det migrationsrättsliga This essay examines the role of procedural rules in the field of Swedish migration law, as this role is expressed through a number of procedural features that are special for migration law. The essay focuses on whether the procedural rules of Swedish migration law tend to prioritize the individual’s procedural safeguards or procedural efficiency. The first unique feature of the procedural rules o
The focus of this work has been to implement a generic netlist reduction engine to speed up circuit simulations. The netlist reduction techniques are further optimized for Static Random-Access Memory (SRAM), wherein we exploit the repetitive pattern of the circuit. There are many driving factors for developing a netlist reduction engine for SRAM simulations. In today's System on Chip (SoC), S
Sverige är en rättsstat som bygger på många olika principer för att kunna för-säkra ett fungerade rättsväsende. En viktig sådan är principen om domens orubblighet. De domar som en domstol meddelar ska stå fast när dessa vunnit laga kraft, vilket kallas för en doms negativa rättskraft. Vidare har de mänsk-liga rättigheterna som inkorporerats i svensk lagstiftning genom EKMR en stor plats vid lagstiSweden is a state governed by the rule of law, and is based on many different principles in order to ensure a functioning justice system. An important prin-ciple is that the rulings from the courts should be adamant, also known as the principle of firmness. The ruling of the court shall stand when it has gained legal force and this is also known as the negative legal force of a judgment. The human
The aim of the study at had was to explore the potential of Natural Capital Accounting (NCA) to integrate environment into business decision-making. In order to fulfill the aim, the research was split into three main parts. First, the existing views on what constitutes NCA were reviewed through a literature analysis of grey literature, and the working definition established. The study found that t
With the climate change and urbanization process, the frequency of the urban flooding’s occurrence has increased in the recent years. It brings great economic losses to the cities, especially to the basements of individual properties. Low Impact Development (LID), which currently advocated by more city planners for managing stormwater, is considered as a more sustainable way to mitigate urban floo
Att vittna är en lagstadgad skyldighet i Sverige. Om man vägrar att inställa sig som vittne trots att man är kallad riskerar man att tvångsmedel riktas mot en. Under senare tid har möjligheten till anonyma vittnesmål diskuterats på en rad olika håll i samhället, då man allt oftare ser en ovilja att vittna på grund av rädsla att drabbas av repressalier. Enligt en allmän uppfattning är det inte tillTo testify is a statutory duty in Sweden. If one refuses to testify, even though one are called by the court, one risks that compulsions will be directed towards one. Recently, the possibility of anonymous testimony has been discussed in the Swedish society, as the reluctance to testify has increased due to the fear of reprisals. But according to the general view in Sweden, it is not allowed to wi
Nya system skapar svårigheter då man inte kan använda redan etablerade metaforer, designer eller sätt att beskriva och prata om systemet. Detta arbetet ämnar att underlätta arbetet med sådana system genom att erbjuda designprinciper och metodiker för att jobba med dem och undersöka vilka svårigheter man behöver vara medveten om. För att forma och testa nya designprinciper och metodiker så genomföOne of the difficulties in designing new products is the absence of already tried metaphors, designs or ways to talk about the system. This thesis focuses on methods and practises one could potentially use when designing something new - and if there are any challenges one need to aware of as a designer of such a system. In order to devise, and test, these practices and methods, an example system
