The response of clouds to the changes in climate is uncertain, and the representation of the cloud-climate feedback is a key challenge in the global circulation models (GCM) for future climate projections. Factors contributing to this uncertainty include processes that involve particles of various sizes and phases, as well as the interactions between these particles and the surrounding atmosphere.
This study investigates temporal relationships between vegetation growth, rainfall, and soil moisture for six sites located in sub-Saharan and southern Africa for the period 2005-2009. Specifically, seasonal components of time series of Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) composites from the Moderate Resolution Imaging Spectroradiometer (MODIS) and hal
Länders kreditbetyg är ständigt i fokus i dagens europeiska skuldkris. I denna uppsats undersöks därför vilka riskpremier som kan förväntas till följd av ändringar i kreditbetyg eller utsikter från något av de tre största kreditvärderingsinstituten; Moody´s, Standard and Poor´s och Fitch. Ett antal ekonometriska modeller konstrueras utifrån ett datamaterial som omfattar 11 EMU-länder under tidsper
Purpose: To investigate if it is possible to earn abnormal returns from the accruals based trading strategy in Sweden. The aim is also to examine if the benchmark used when classifying firms into accruals portfolios has an impact on the abnormal returns from the trading strategy. Methodology: The study investigates the abnormal returns from the trading strategy that aims to exploit the accruals a
In this report we present the testing and development made using the Lund Observatory Vacuum Echelle Spectrograph (LOVES) during the last few years. Hardware development includes an assembly from base components due to relocation and necessary calibrations of the optics. Software devel- opment includes the making of a basic image processing pipeline for the instrument. The testing of LOVES wavelen
This paper empirically examines the relationship between fuel prices and patenting activity in environment-friendly technologies in the auto industry across the OECD countries for the period 1994-2011. Overall, the results suggest that tax-inclusive fuel price affects innovative activity in environment-friendly technologies. More specifically, the analysis shows that the technologies aiming to red
This study looks at the investment decision-making process of institutional Venture Capitalists. Prior research has shown that general criteria for the valuation of new ventures have not significantly changed over time. Studies looking at the stage-specific criteria however consider different factors important. Using the verbal protocol method in the screening phase with two venture capitalists, w
This study aims to add new knowledge to our understanding of poverty as a multidimensional phenomenon and focuses on the links between poverty and gender norms and practices. The overall research question that this study is concerned with is about the effect of self-help group participation on women’s self-perceptions of options, their access to social, economic and cultural capital, and subsequ
Purpose: To examine how investors’ portfolio exposure in a concentrated ownership-structure affects abnormal returns for the bidding company in a merger and acquisition on the Swedish market Methodology: Quantitative research approach with an event study to explore cumulative abnormal return, multivariate regression analysis Theoretical Perspective: Agency theory, M&A wealth effects, empire
The beneficial effects of HLA matching at the HLA-A, -B and -DR loci on recipient short- and long-term survival in heart transplants have been established in a number of studies. The objective of the present study was to evaluate the importance of individual HLA alleles at the HLA-A, -B and -DR loci as risk factors for recipient death within one year after transplant by using artificial neural net
