This thesis looks at the effects a coffee cooperative in the municipality of Salgar has on its member farmers, and its implication for rural development in the region. Coffee cooperatives have become important strategic institutions within the coffee sector in the country, instigated by the National Coffee Growers Federation. It is the only agricultural sector in the country where farmers can be g
In the past people sought for information via libraries, travel magazines or were inspired by marketing the travel agency made in order to attract consumers. Before the Internet era one way communication was the right way to follow. Since Internet was developed two ways communication has evolved and people can talk to each other worldwide. The development of the two ways communication has created
The aim of this study is to get closer to the complex cultural expression of performance art through its relation to the body and the phenomenon of presence. The investigation is based upon two analysis of performance artworks such as the virtual performance installation Telematic Dreaming (1992) by Paul Sermon, and the live performance The Artist is Present (2010) by Marina Abramovic, which is a
The Swedish carbon tax of 1991, one of the first of its kind, has positioned Sweden as a forerunner in climate governance. It is often depicted an international success and today constitutes the backbone of Swedish climate policy. At first, however, the tax received widespread criticism and had limited political support. The policy design process was short, with limited time for deliberation. Whil
Differential equations are an important building block for modeling processes in physics, biology, and social sciences. Usually, their exact solution is not known explicitly though. Therefore, numerical schemes to approximate the solution are of great importance. In this thesis, we consider the temporal approximation of nonlinear, nonautonomous evolution equations on a finite time horizon. We pres
In this article I rethink international migration law by analysing the Model International Mobility Convention (MIMC) through a concrete-utopian lens. Starting from the premise that coloniality remains an active structure of the global order, I show how progressive legal projects often reproduce the hierarchies they seek to overcome. Combining Gary Wilder’s concrete utopianism with Ruth Levitas’s
The scaling relations between the gas content and star formation rate of galaxies provide useful insights into the processes governing their formation and evolution. We investigated the emergence and the physical drivers of the global Kennicutt-Schmidt (KS) relation at 0:25 ≤ z ≤ 4 in the cosmological hydrodynamic simulation NewHorizon, capturing the evolution of a few hundred galaxies with a reso
Popular Abstract in Swedish Bakgrunnen for den foreliggende avhandling er et ønske om å utnytte moderne tredimensjonell bildeanalyse for å forbedre undersøkelse og tolkning av synsnervehodets (papillens) form og størrelse (topografi). Synsnervehodet representerer den delen av synsnerven som trer inn i bakre del av øyet gjennom senehinnen (sklera). Den normale synsnerve har ca 1.2 millioner nervetrEvaluation of the optic nerve head topography is one of the most important methods to diagnose and monitor patients with glaucoma. Until recently, optic nerve head topography has most often been judged by either ophthalmoscopy or from optic disc photographs. These methods are subjective and examiners do not have access to absolute measurements of the optic disc size and cup depth. The result of su
Popular Abstract in Swedish Kol-kolinteraktioner utgör starka kemiska bindningar. Detta innebär att de är relativt svåra att både bryta och bilda. Föreliggande avhandling sammanfattar mekanistiska studier av två reaktioner, Stillereaktionen och Heckreaktionen, med hjälp av vilka kol-kolbindningar kan bildas. Ett vanligt förekommande sammanfattningsnamn för denna typ av reaktioner är korskopplingsrThe present thesis deals with various types of palladium(II) and platinum(II) complexes and their use in homogeneous catalysis. The focus has been devoted to mechanistic investigations concerning the Stille and Heck reactions and studies under both catalytic and stoichiometric conditions were conducted. As a stoichiometric probe for studying the transmetallation step in the Stille reaction the pl
Low-dimensional narrow-band-gap III-V semiconductors are key building blocks for the next generation of high-performance nanoelectronics, nanophotonics, and quantum devices. Realizing these various applications requires an efficient methodology that enables the material dimensional control during the synthesis process and the mass production of these materials with perfect crystallinity, reproduci
Progressive supranuclear palsy and Parkinson's disease have distinct underlying neuropathology, but both diseases affect cognitive function in addition to causing a movement disorder. They impair response inhibition and may lead to impulsivity, which can occur even in the presence of profound akinesia and rigidity. The current study examined the mechanisms of cognitive impairments underlying disin
This chapter examines the evolution of REDD+ governance and identifies policy options to increase synergies among REDD+, the sustainable management of forests and biodiversity conservation. REDD+ emerged at the international level as a point of convergemnce acorss the 'institutional complexes' of forests, climate and biodiversity. This convergence attracted the engagement of a wide range of instit

We discuss whether the enhancement in the diphoton final state at Mgg = 750 GeV, observed recently by the ATLAS and CMS Collaborations could be a neutral pseudoscalar technipion π∼0. We considered two distinct minimal models for the dynamical electroweak symmetry breaking. Here we concentrate only on two-flavor vector-like technicolor model and we assume that the two-photon fusion is a dominant pr
The age of wearable technology devices is upon us. These devices are available in many different form factors including head-mounted displays (HMDs), smartwatches and wristbands. They enable access to information at a glance. They are intended to always be ‘‘on’’, to always be acting and to always be sensing the surrounding environment in order to offer a better interface to the real world. A tech
Can an educational programme develop tomorrow’s leaders? Can the mindset and skill set found in successful leaders be taught and learnt in educational programmes? This paper presents a leadership program, a cross disciplinary master programme atLund University, Sweden. The students study technology and management, however, the programme’s unique value proposition lies in its focus on leadership.Th
We study the effects of two dimensions of teacher quality, subject knowledge and didactic skills, on student learning in francophone Sub-Saharan Africa. We use data from an international large- scale assessment in 14 countries that include individual-level information on student achievement and country-level measures of teacher subject knowledge and didactic skills in reading and math.

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
Asteroid material is detected in white dwarfs (WDs) as atmospheric pollution by metals, in the form of gas/dust discs, or in photometric transits. Within the current paradigm, minor bodies need to be scattered, most likely by planets, into highly eccentric orbits where the material gets disrupted by tidal forces and then accreted on to the star. This can occur through a planet-planet scattering pr
Cities are seen as one of the leading forces in making our societies sustainable and resource efficient. The latest trends of sharing homes, cars, bikes, tools and other goods are fast entering our urban lives. The sharing economy is a consumption-production mode in a city, in which value is generated through transactions between peers or organisations that offer access to their idling or underuti
