Given the widespread underemployment in Africa, on-the-job search represents a key channel through which individuals seek better employment oppor- tunities that value their skills and competences. However, empirical research on the determinants of on-the-job search has almost exclusively been conducted in advanced economies. The study aims to identify the determinants of on-the-job search among di
Investigating the discourse around development aid and cooperation yields insights into development policy choices and their public legitimisation and justification because of the recognised opinion-forming effect that public information, especially media, has on the public. Hence, public development discourse informs and shapes how ordinary people make sense of development issues and the perceive
The spread of invasive alien species poses great risks for biodiversity, human health and economies. Impatiens glandulifera, an invasive alien plant which has been listed in The European list of Invasive Alien Species of Union concern, is widely spread in Sweden. Multiple studies have been made regarding the plant’s characteristics, spread and impacts on invaded areas. The purpose of this study i
This paper explores how electrical appliances, together with the idea of attaining energy access in the near future, create hope in a northern village in Malawi. Even though less than one per cent of the rural population has energy access, some of these locals already own solar systems. Nevertheless, their solar equipment is not powerful enough to generate the large amounts of energy required to r
Historiskt sett har transportören, med undantag för force majeure och krigshandlingar, varit strikt ansvarig för all skada på det transporterade godset. Detta kom att förändrades under slutet av 1800-talet och början av 1900-talet när transportörerna började begränsa sina ansvarsgrunder med klausuler i transportavtalen. Snart var transportörerna inte ansvariga för i princip någonting, vilket var pThe carrier has historically been strictly liable for all damage to the cargo carried, with the exception of acts of God and war. This changed during the late 1800’s and early 1900’s when the carriers began to limit their liabilities in the contract of carriage. They were soon not liable for very much which was problematic for the shippers, since they did not receive compensation when their goods
Transition to later childbearing regimes is a distinct feature of nations in the developed world. Simultaneously, the overall continuation of the declines in fertility experienced by several European nations motivated the study of the relation between postponement and complete fertility. Several widespread theories established negative associations incorporating the idea of opportunity costs assoc
Region Skåne has designated seven regional centers in Skåne: Malmö, Lund, Helsingborg, Landskrona, Hässleholm, Kristianstad and Ystad. These centers are to be, among other things, providers of key services. The aim of this thesis is to examine whether Skåne’s students have equal opportunity, through public transport, to benefit from the regional centers’ provision of gymnasiumlevel education. This
Denna masteruppsats syftar till utvecklandet av en industriellt, fullskalig modell över en vattenreningsprocess som syftar till simultan sulfatreduktion och tungmetallåtervinning från processvatten vid gruvdrift. Den mängd sulfat som finns tillgänglig i lakvattnet, omvandlas till vätesulfid med hjälp av sulfatreducerande bakterier (SRB). Tungmetallerna återvinns genom selektiv utfällning med hjälpThis thesis treats the development of an industrial scale models of a wastewater treatment process aiming at reducing the sulfate and heavy metal concentration in the effluent water from mining processes. The sulfate present in the process water is reduced using sulfate reducing bacteria (SRB) while the heavy metals are recovered through selective precipitation using the hydrogen sulfide produced
Far-field three dimensional x-ray diffraction (3DXRD) data acquired by repetitive acquisitions with a beam much smaller than the sample width is sometimes referred to as scanning-3DXRD. We here analyse the scanning 3DXRD approach and present a novel reconstruction technique capable of reconstructing intra-crystal variations in crystal structure from a set of recorded 2D diffraction patterns. The m
Det finns idag robotar som är särskilt anpassade för att användas av räddningsteam i följderna av katastrofer som hjälpmedel i deras arbete att lokalisera och rädda människor instängda i trånga utrymmen. De är dock mycket dyra vilket begränsar deras användande och gör att användarna tvekar innan de skickar in en robot med risken att skada eller förlora den. Detta projekt dokumenterar det första stRobots currently exist that are specifically designed for use in the wake of disasters to help rescue teams in their work of locating and rescuing individuals trapped in confined spaces. However, they are prohibitively expensive which limits their adoption and causes the operators to think twice before they're deploying a robot with the risk of losing or damaging it. This project details the f
The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. The PA core consists of a cross-coupled pair of NMOS transistors with an NMOS current source. This st
It is of importance for manufacturing companies to get an overview of costs associated with production. This thesis handles this subject with an emphasis on chosen cutting data as well as chosen tools since this has a large impact of the tooling cost. By modelling on cutting data available from tool manufacturers, cutting data can be implemented to test different cases in the production. This also
This study examines the effect of credit rating downgrades and negative changes in outlook on stock returns for companies in the London Stock Exchange from 2000 to 2018. Measuring the abnormal returns, we verify if the observed stock returns are significantly different from the expected returns calculated through an event study. A market model with the FTSE All-Share Index as a benchmark is used.
Once the South African dung beetle Kheper lamarcki has constructed its ball of dung, it strives to escape the competition at the dung pile and locate soft ground to dig down. The most efficient way to do this is to move away along a straight path. One way to achieve this is by using celestial cues as orientation references. However, when these cues fail to provide sufficient directional informatio
The climate change is affecting small island developing states to the amount that the surface of Tuvalu might disappear and the country therefore risk to lose its sovereignty (Pacific Small Island Developing State 2009, p. 10-12). By investigating environmental security through climate displacement this thesis will conduct a case study of Tuvalu. The theory of ecofeminism and intersectionality wil
Density is often used as a strategy to achieve a sustainable development in contemporary urban planning. A higher concentration in the urban environment of functions and people are argued to be essential to handle the climate change as well as achieving social equity. While a desire for higher density is often formulated in urban development plans by regions or municipalities, there lies a confusi
The techno-conglomerate Amazon has emerged as a corporate giant, branching out their operations to include many sectors of the global market. While previously concealing their carbon footprint, Amazon co-founded The Climate Pledge together with two former architects of the Paris Agreement in 2019 with the goal of reaching net zero carbon by 2040, ten years earlier than the Paris agreement. A copio
This paper analyzes trade in services’ vulnerability to exogenous shocks in order to contribute to the often-neglected area of international trade in services. It is accomplished by examining how Sweden’s border measures during the European refugee crisis affected services trade between Sweden and Denmark. The impact of the border measures is estimated with a difference-in-differences model: Swede
