The aim of this paper is to combine remote sensing data with geo-coded household survey data in order to measure the impact of different socio-economic and biophysical factors on maize yields. We use multilevel linear regression to model village mean maize yield per year as a function of NDVI, commercialization, pluriactivity and distance to market. We draw on seven years of panel data on African

The Swedish Medical Products Agency (MPA) objects to the fact that we occasionally refer to one of its senior ex-employees by name. However, names of individual MPA assessors, FDA reviewers, and EMA rapporteurs and co-rapporteurs are reported in regulatory documents and are a matter of public record. In our paper we in no way suggest that regulatory decisions were left to individual reviewers or a

Perhaps the most important unmet clinical need in Parkinson's disease (PD) is the development of a therapy that can slow or halt disease progression. Extensive preclinical research has provided evidence for the neurorestorative properties of several growth factors, yet only a few have been evaluated in clinical studies. Attempts to achieve neuroprotection by addressing cell-autonomous mechanisms a

Aims: We tested the association between alcohol use disorder (AUD) and divorce; estimated the genetic and environmental influences on divorce; estimated how much genetic and environmental influences accounted for covariance between AUD and divorce; and estimated latent genetic and environmental correlations between AUD and divorce. We tested sex differences in these effects. Design: We identified

Lack of recovery from everyday strains and demands is connected to increased levels of stress-related problems and development of ill-health. There is much research on how to handle and prevent fatigue and stress in leisure time, but research on working time is more scarce. A recent study found that employees' experience of recovery during working hours was related to high self-rated health. OBJEC

Technical biases are introduced in omics data sets during data generation and interfere with the ability to study biological mechanisms. Several normalization approaches have been proposed to minimize the effects of such biases, but fluctuations in the electrospray current during liquid chromatography-mass spectrometry gradients cause local and sample-specific bias not considered by most approache

Planar droplet sizing (PDS) is a technique relying on the assumption that laser-induced fluorescence (LIF) and Mie scattering optical signals from spherical droplets depend on their volume and surface area, respectively. In this article, we verify the validity of this assumption by experimentally analyzing the light intensity of the LIF and Mie optical signals from micrometric droplets as a functi

Purpose: The purpose of this thesis is to study if and how Swedish accounting regulation create misunderstandings between Swedish aid agencies and stakeholders. Further we are going to analyze if there is a need to improve Swedish accounting regulation to increase faith between the agency and its stakeholders. Methodology: The study is based on a qualitative approach and the primary sources consis

Zirkon (ZrSiO4) och baddeleyit (ZrO2) är två vanliga zirkoniuminnehållande mineral som båda är viktiga för U-Pb-geokronologi. Zirkon är stabilt under kiselmättade förhållanden medan baddeleyit under kiselmättade förhållanden torde reagera med det tillgängliga kislet och bilda zirkon. Trots detta har baddeleyit observerats som interna domäner i zirkon i kiselmättade bergarter från exempelvis sydväsZircon (ZrSiO4) and baddeleyite (ZrO2) are two common zirconium bearing minerals which are important for U-Pb geochronology. Zircon is stable at silica saturated conditions, while baddeleyite should react with the free silica to form zircon under the same conditions. Yet, baddeleyite have been observed as intergrowths within zircon grains in silica saturated rocks, e.g. from southern West Greenlan

Al-Ga-based alloys are promising carriers of renewable energy, which can provide hydrogen by hydrolysis in challenging working environments. Manipulating their performance by different process conditions and comprehending the mechanisms are important for achieving directional design synthesis of alloys and enhancing their practicality. This study presents a novel approach to optimizing the hydroge

Recognizing the challenges in using botanicals as sustainable pest control agents due to compositional variation, this study addresses the limitations of traditional component-based approaches such as Hewlett and Plackett or Wadley’s models. Based on the assumption of noninteractivity among constituents, these models often fail to predict outcomes accurately due to dynamic intermolecular interacti

In this essay I discuss different normative foundations - theories of political ethics, for proposed cures to market failures. In addition to empirically match what cure fit what type of market failure, I posit the notion that the normative position of an economist, or policy maker, or of a group, concerned with these problems, delimits the options available for recommending, or analysing, what co

En av de stora utmaningarna inom den internationella handelsrätten idag är hur man ska kunna förbättra situationen för utvecklingsländer inom den internationella handeln. Denna uppsats belyser specifika undantagsregler, inom WTO-rätten, som har till ändamål att öka utvecklingsländers möjligheter att delta i den internationella handeln. Industriländer tilldelar utvecklingsländer, i enlighet med WTOOne of the current challenges within the field of international trade law is how to meet the special needs of developing countries and how to a greater extent include these countries in the world trading system. This thesis examines a particular set of exception rules that exist on behalf of developing countries. Developing countries are, in accordance with WTO law, granted different tariff prefer

Hazardous situations involving radioactive, chemical, and other dangerous materials pose significant risks to emergency responders. In such situations, robots can support civil forces in reconnaissance and mitigation. However, this requires the development of robotic systems with novel AI-based assistance functions, operation procedures, and raises new ethical and legal questions. To address these

Background: Ageing-in-place policies have increasingly shifted elder care responsibilities onto family members. Among older cohabiting couples, one’s partner’s illness significantly impacts the other’s daily life and well-being.Aim: To explore the responsibilities and strategies of caregiving partners in older cohabiting couples from the perspectives of cohabiting caregivers.Methods: A qualitative

Green ammonia synthesis from nitrogen via photocatalysis and electrocatalysis has emerged as a pivotal research focus in sustainable chemical processes. The efficient catalytic reduction of nitrogen necessitates concurrent nitrogen activation and hydrogen evolution suppression, representing a significant challenge. In this study, CuAu bimetallic-modified TiO2 catalysts were developed and engineere
