Contemporary institutions engaged in extending micro-loans do not usually grant such loans to the poor due to the latters’ inability to provide appropriate collateral and their insufficient creditworthiness. In modern times the Dutch East-India Company created a financial instrument called the “transportbrief” which enabled poor employees of the Company to obtain loans on the financial market. The

This paper presents estimates of the level of per capita GDP and of the distribution of income of preindustrial Poland. This is based on a reconstruction of a social table of the Voivodeship of Cracow for 1578. Our evidence indicates that income in Poland was distributed more equally than in contemporary Holland. However, the extraction rate in the Voivodeship was much higher than in the North Sea

Urban flooding is of growing concern due to increasing densification of urban areas, changes in land use, and climate change. The traditional engineering approach to flooding is designing single-purpose drainage systems, dams, and levees. These methods, however, are known to increase the long-term flood risk and harm the riverine ecosystems in urban as well as rural areas.

Following a macroeconomic stabilization and consistent economicgrowth during the 2000s, Brazil experienced a continuous decrease on povertyincidence for the first time in its contemporary history. While the literatureemphasizes the importance of economic growth alongside social developmentto fight poverty, the Brazilian experience also displays strong governmentaction through expanding social cove

The vibrational stability of a horizontally deflecting double-crystal monochromator (HDCM) is investigated. Inherently a HDCM will preserve the vertical beam stability better than a `normal' vertical double-crystal monochromator as the vibrations of a HDCM will almost exclusively affect the horizontal stability. Here both the relative pitch vibration between the first and second crystal and the ab

Johan Lindgren introduces fossil pigments.

Bacterial genomes typically consist of a single chromosome and, optionally, one or more plasmids. But whole-genome sequencing reveals about ten per-cent of them to be multipartite, with additional replicons which by size and indispensability are considered secondary chromosomes. This raises the questions of how their replication and partition is managed without compromising genome stability and of

Time-resolved experimental techniques are increasingly abundant at storage ring facilities. Recent developments in accelerator technology and beamline instrumentation allow for simultaneous operation of high-intensity and timing-based experiments. The MAX IV facility is a state-of-the-art synchrotron light source in Lund, Sweden, that will come into operation in 2016. As many storage ring faciliti

Vi vet att laddade partiklar sänder ut elektromagnetisk strålning då de tvingas följa en krökt bana. Denna strålning kallas synkrotronstrålning, och upptäcktes i mitten av 1900-talet. Sedan dess har denna typ av strålning funnit tillämpningar inom flera forskningsområden såsom kemi, biologi, medicin och materialvetenskap. För att uppfylla de växande kraven på vissa strålningsegenskaper, är partikeIn this thesis several aspects related to a new generation of storage ring light sources are discussed. Due to a reduction of electron beam emittance, fourth generation storage rings provide synchrotron radiation sources close to the diffraction limit at X-ray wavelengths. This results in a significant increase in photon brightness that is beneficial in a variety of synchrotron radiation based exper

Background: Recent research has shown that acoustic white noise (80 dB) can improve task performance in people with attention deficits and/or Attention Deficit Hyperactivity Disorder (ADHD). This is attributed to the phenomenon of stochastic resonance in which a certain amount of noise can improve performance in a brain that is not working at its optimum. We compare here the effect of noise exposu

The gender pay-gap is not a new phenomenon in Brazil. Since the increase of female participation on the labor market, the gap has remained a persistent problem that has generated a wide range of studies on the topic. The Human Capital Theory argues that individuals’ education and on-the-job experience are essential determinants on wage estimations. This assessment is not disputed in the literature
