The theory of parental investment and brood sex ratio manipulation predicts that parents should invest in the more costly sex during conditions when resources are abundant. In the polygynous great reed warbler, Acrocephalus arundinaceus. females of primary harem status have more resources for nestling provisioning than secondary females, because polygynous males predominantly assist the primary fe
Popular Abstract in Swedish Syftet med den här avhandlingen är att studera några av de problem som är förknippade med implementering av så kallad autentisk bedömning i lärarutbildningen. I den första delen av avhandlingen undersöks, genom en litteraturöversikt, huruvida användningen av bedömningsmatriser kan fungera som ett stöd för ökad tillförlitlighet och trovärdighet vid bedömning av komplexa The aim of this dissertation is to explore some of the problems associated with introducing authentic assessment in teacher education. In the first part of the dissertation the question is investigated, through a literature review, whether the use of scoring rubrics can aid in supporting credible assessment of complex performance, and at the same time support student learning of such complex perfo
Comparative genomic hybridization (CGH) analysis has shown that chromosome 5q deletions are the most frequent aberration in breast tumors from BRCA1 mutation carriers. To map the location of putative 5q tumor suppressor gene(s), 26 microsatellite markers covering chromosome 5 were used in loss of heterozygosity (LOH) analysis of breast tumors from BRCA1 (n = 42) and BRCA2 mutation carriers (n = 67
In a prospective study comprising 310 consecutive patients with carcinoma of the cervix, FIGO stages I-IV, the prognostic significance of clinical and flow cytometric variable was evaluated in a univariate and multivariate analysis. The parameters studied included stage according to FIGO, age, histopathologic grade according to Ackerman and MGS scores, DNA ploidy, S-phase fraction as well as treat
Perceptual consumer requirements are often disregarded in the product development process. The consequence of this is that products may become more attractive to the design practitioners than to the target consumers. This paper describes the development of a new internet based tool, VIPET (Visual Internet Product Emotion Tool), that can be used for global evaluation of visual product qualities by
© 2017 Metal cutting simulations have become an important part of cutting tool design and the research in the field in general. One of the most important aspects of modeling is the accuracy of the tool geometry. 3D microscopy is used for measuring the tool edge radius with good accuracy. However, especially with sharp tools, i.e. small tool edge radii, the measurements, no matter how accurate, are
I present higher loop order results for several calculations in Chiral perturbation Theory. 1) Two-loop results at finite volume for hadronic vacuum polarization. 2) A three-loop calculation of the pion mass and decay constant in two-flavour ChPT. For the pion mass all needed auxiliary parameters can be determined from lattice calculations of ππ-scattering. 3) Chiral corrections to neutron-anti-ne
Background: Many stroke survivors suffer from sensory impairments of their affected upper limb (UL). Although such impairments can affect the ability to use the UL in everyday activities, very little attention is paid to sensory impairments in stroke rehabilitation. The purpose of this trial is to investigate if sensory re-learning in combination with task-specific training may prove to be more ef
Långvarig smärta är ett vanligt förekommande och tärande tillstånd som är bland de mest kostsamma hälsoproblemen för både individen och samhället som helhet. Kognitiv beteendeterapi (KBT) är den mest spridda psykologiska behandlingen för långvarig smärta. Även om metoden är evidensbaserad och rekommenderad ger den relativt blygsamma förbättringar för smärtrelaterad funktion och medföljande emotionChronic pain is a commonly occurring and debilitating condition, and among the costliest health problems for both the individual and society at large. Cognitive behavioral therapy (CBT) is the most widely-disseminated psychological treatment for chronic pain. Even though it is recommended and evidence-based, it yields quite modest improvements in pain-related functioning and accompanying symptoms
A search for high-mass resonances decaying to τν using proton-proton collisions at s=13 TeV produced by the Large Hadron Collider is presented. Only τ-lepton decays with hadrons in the final state are considered. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 36.1 fb-1. No statistically significant excess above the standard model expectation is observe
Recent conceptual studies identify gain, normative and hedonic factors as three categories of motivations of consumer proenvironmental behavior. However, empirical understanding of how these motivations interact and affect proenvironmental behavior is limited. This study is based on a survey of car owners in Sweden (N = 573) and uses structural equation modeling to analyze the data. The empirical
This study contains a series of laboratory experiments designed to describe the lateral movement and spatial variability of an infiltrated dye tracer across the capillary fringe of homogenous sand in an aquarium. A combination of image analysis and geoelectrical monitoring was used to track the flow paths of the dye with different hydraulic gradients and infiltration rates. Photographs were taken
The stable carbon isotope ratio (δ13C) is a key tool in tracing the source of carbon within and across ecosystems. In isotope mixing models dissolved organic carbon (DOC) from terrestrial sources is often assigned a fixed δ13C of roughly -28‰ to -27‰ in C3 plant-dominated areas. However, the claim of a uniform δ13C distribution for terrestrial DOC sources of different reactivity has seldom been te
Lignocellulosic biomass is a promising alternative fuel source which can promote energy security, reduce greenhouse gas emissions, and minimize fuel consumption when paired with advanced combustion strategies. Pyrolysis is used to convert lignocellulosic biomass into a complex mixture of phenolic-rich species that can be used in a transportation fuel. Anisole (or methoxybenzene) can be used as a s
Atherosclerosis and its clinical consequences are the leading cause of death in the western hemisphere. While many studies throughout the last decades have aimed at understanding the disease, the clinical markers in use today still fail to accurately predict the risks. The role of the current main clinical indicator, low density lipoprotein (LDL), in depositing fat to the vessel wall is believed t
The work presented in this thesis has aimed to improve the knowledge about the groundwater occurrence in different geological conditions in Mozambique. The main focus in this study has been on the understanding of hydrogeological conditions in area with little background information by use of geophysical investigation. The lack of background information is a problem in many countries because the
Background: The rapid adoption of robot-assisted laparoscopy in radical prostatectomy has preceded data regarding associated costs. Qualitative evidence regarding cost outcomes is lacking. Objective: This study assessed how costs were affected by robot-assisted laparoscopic prostatectomy (RALP) compared with open surgery. Design, setting, and participants: Cost analysis was based on the dataset of
