Based on a novel dataset of about 1150 time series, this study provides monthly economic activity estimates for 28 countries during the Great Depression. Due to their high frequency, the indices reveal that steady growth was far from universal even in the second half of the 1920s. Monetary and financial instability, agricultural crises, and labor conflict continued to plague economies around the g
Tillgång till pollinerare är avgörande för produktionen av många grödor. Det är viktigt att känna till olika insektsarters egenskaper och att skapa förutsättningar för en mångfald av pollinerare. Det kan i vissa situationer uppstå risk för konkurrens mellan vilda bin och honungsbin.
This dissertation is composed of six chapters. Based on a comparison with other recessions throughout history, the first chapter motivates studying the Great Depression from a trade perspective. The second chapter sets the stage for such an endeavour. It introduces a new macroeconomic dataset for the interwar period and investigates the prelude and global impact of the Great Depression.

I estimated population size of fifty-nine common birds by using the fixed routes of the Swedish Bird Survey (SBS), which give the number of birds per kilometer. I converted this number to density, birds/km2, using the correction factors for detectability that have been developed for line transects in Finland. I compared the population estimates by this new method with those in a previous account f
The recent surge in publications on the history of knowledge may obscure the fact that there are several parallel understandings of what the field is. In this article, I discern five major historiographical directions in contemporary scholarship regarding the history of knowledge. The analytical framework that has so far attracted the most attention is the circulation of knowledge. As productive a
Unprecedented eviction, peripheral resettlement and simultaneous redevelopment of the urban spaces in the biggest megacity of postcolonial India – Mumbai reflect its development paradox, accumulation and dispossession processes, and rapidly transforming state, market, civil society and community relations. The vision of transforming Mumbai into a ‘world-class’, ‘slum-free’ city emerged in late 199
A Great Tit Parus major without any yellow pigment in the plumage was ringed in southern Swedish Lapland in 2006. Such pale birds are known to appear with a low frequency throughout the species’ range. Superficially they look like the eastern (sub)species Parus (major) minor. The focal bird was a yearling with a wing length well above that of minor so there is no reason to suspect eastern origin.

Water scarcity is a consequence of complex interactions between water access and water use. In fact, the time period over which precipitation deficit accumulates is a determing factor for the occurrence of drought. Drought induces crop production losses and far-reaching societal effects. In the South American Altiplano, drought is a major hazard. Here, drought leads to food shortages, malnutrition
Sewage ponds with exposed sludge are known to be excellent feeding sites for waders during migration. They still exist in parts of the world but are disappearing in pace with introduction of modern methods which do not involve open exposure of the sludge. Here I report a five-year study from a Swedish plant with open sludge ponds in the 1950s when many similar ones were still active. I counted the
The district heating (DH) customer installations in current DH systems contain a variety of different faults that cause the return temperatures of the systems to increase. This is a major problem, since the focus in theDH sector is to decrease the system temperatures in order to utilize more low-temperature heat. Therefore, this study has focused on how utilities are currently working to keep theiThe district heating (DH) customer installations in current DH systems contain a variety of different faults that cause the return temperatures of the systems to increase.

Introduction: Recovery following distal radius fracture (DRF) is generally achieved within six months. However, a minority of patients experience functional impairments over a longer period. Traditional outcome measures are grip strength and range of movement. However, this may not reflect all parameters that are important. This study focuses on grip function as well as occupational performance in
Parton shower algorithms are key components of theoretical predictions for high-energy collider physics. Work toward more accurate parton shower algorithms is thus pursued along many different avenues. The systematic treatment of subleading color corrections in parton shower algorithms is, however, technically challenging and remains elusive. In this article, we present an efficient and numericall
We compute the next-to-leading-order corrections to soft-gluon radiation differentially in the one-emission phase space. We show that their contribution to the evolution of color dipoles can be obtained in a modified subtraction scheme, such that both one- and two-emission terms are amenable to Monte Carlo integration. The two-loop cusp anomalous dimension is recovered naturally upon integration o
I denna uppsats anläggs ett kunskapshistoriskt perspektiv på Svenska Dagbladets dagliga essäsida Under strecket och 1960-talets kunskapscirkulation. Genom att studera några tongivande skribenter och ett stort antal understreckare karakteriseras den akademiska kunskapens plats och form i tidens svenska offentlighet. På ett teoretiskt plan griper uppsatsen in i den vetenskapliga diskussionen om kuns
