Title: Expressions of grief - a social psychological study Authors: Christel Hagdahl, Linn Bengtsson Supervisor: Anders Östnäs The purpose of this study was to describe and analyze human grief via social media from a social psychological perspective. We found it interesting to study blogs to illustrate the diversity in expressions of grief and to analyze which social norms that influence the proce
We study how processing states alternate during information search tasks. Inference is carried out with a discriminative hidden Markov model (dHMM) learned from eye movement data, measured in an experiment consisting of three task types: (i) simple word search, (ii) finding a sentence that answers a question and (iii) choosing a subjectively most interesting title from a list of ten titles. The re
In low-and middle-income countries, inadequate sanitation results in faecal contamination of the water used by urban farmers for irrigation. Consumers of raw contaminated vegetables run the risk of developing diarrhoeal diseases and helminth infections, which are a leading cause of under-five mortality and impact the well-being and productivity of millions of adults. This review identifies the evi
Existing research on urban Ghana mainly focuses on processes occurring within the country’s major cities, thereby reproducing a trend within the social sciences to overlook the role of intermediate and secondary cities. This paper aims to address this shortcoming by exploring spatial and social transformations in Sekondi–Takoradi, one of Ghana’s secondary cities and the metropolitan area serving t
Populärvetenskaplig sammanfattning: Jordens klimat står under ständiga variationer och förändringar, och det är inte alltid lätt att sära på orsak och verkan bland den mängd av faktorer som styr klimatet. För att kunna reda ut ursprunget till de förändringar som sker, måste de bakomliggande processerna vara väl kända. Sedan är det möjligt att genom matematiska modeller uppskatta de individuella pr
The basis of this thesis is the exit problem in close corporations and the protections available to the minority. The phase one of the problem is when oppression takes place, which includes actions when dividends are withheld and excessive bonuses are paid to the majority, leading to the unfair treatment of the minority. Phase two of the problem is the exit problem itself, the minority owner's
The objective of this study is to classify Swedish land cover classes using multisource satellite data. Multispectral Landsat TM data from April 1993, and multitemporal ERS-1 SAR data acquired seven times during the growing season of 1993 have been used. Nine agricultural and seven forest land cover classes have been analysed. The statistical separabilities between land cover classes have also bee
The aim of the study is to investigate the motives behind emerging economies' military spending. More specifically, answering the question: Why do emerging economies increase their military spending? It does so by analyzing the BRIC countries (Brazil, India, Russia, and China).Drawing from earlier study, it firstly develops an analytical framework consists of three hypotheses, then applies the
Parallel-elastic joints can improve the efficiency and strength of robots by assisting the actuators with additional torques. For these benefits to be realized, a spring needs to be carefully designed. However, designing robots is an iterative and tedious process, often relying on intuition and heuristics. We introduce a design optimization framework that allows us to co-optimize a parallel elasti
The Sörvik granite forms rounded intrusions in the dominating Revsund granite, north-eastern Jämtland, central Sweden. Laser-ablation single-collector magnetic sector field-inductively coupled plasma-mass spectrometry on zircons was used to date the granite. The zircons are inhomogeneous, some with evident cores. The fractionation curves, 207Pb/235U versus time (depth), are irregular and often inc
A series of Na0.67Ni0.33Mn0.67-xSnxO2 (x = 0, 0.01, 0.03, 0.05) materials with mixed P2/P3 phases are synthesized with a conventional solid-state reaction method and investigated as cathode materials for sodium ion batteries. The effects of Sn substitution on the structure and electrochemical performance of the Na0.67Ni0.33Mn0.67O2 are systematically investigated. The substituted samples show smal
Vaccination of neonates and young infants is hampered by the relative immaturity of their immune systems and the lack of safe and efficacious vaccine adjuvants. Immaturity of the follicular dendritic cells (FDCs), in particular, appears to play a critical role for the inability to stimulate immune responses. Using the CD21mT/mG mouse model we found that at 7 days of life, FDCs exhibited a mature p
Background: Recent findings have shown that imaging voluntarily activated motor units (MUs) by decomposing ultrasound-based displacement images provides estimates of unfused tetanic signals evoked by spinal motoneurons’ neural discharges (spikes). Two methods have been suggested to estimate its spike trains: band-pass filter (BPM) and Haar wavelet transform (HWM). However, the methods’ optimal par
In this study, sorption distribution coefficients were determined for 71 pharmaceuticals, aiming to describe their sorption behavior to powder activated carbon (PAC). The data are expected to be applied when designing and upgrading wastewater treatment plants (WWTP) for improved removal of pharmaceuticals by applying sorption to PAC as an additional removal technique. Sorption isotherms were deter
Building on insights from ecological economics and philosophy of technology, this book offers a novel, interdisciplinary approach to understand the contradictory nature of Solar photovoltaic (PV) technology.Solar photovoltaic (PV) technology is rapidly emerging as a cost-effective option in the world economy. However, reports about miserable working conditions, environmentally deleterious mineral
