This study implements a quantitative approach. For calculating excess cash we use Opler et al. (1999) approach. For bid premia model we use Alexandridis et al. (2013) approach. Testing our hypothesis we use regression analysis. We also include a survivorship bias approach. Public acquisitions by firms in the S&P 500 index; we also include dropped firms to bypass survivorship bias. Henceforth w
Hemophilia has evolved from an often fatal hereditary bleeding disorder to a disorder for which safe and effective treatment is available. However, there are several challenges remaining in the treatment of hemophilia. Prophylaxis to prevent bleeding is costly and requires frequent intravenous injections, which are cumbersome for patients. Venous access is often difficult to achieve, especially in
The Ease of Doing Business index, published by the World Bank, ranks countries by how easy it is to do business in them, with the goal of encouraging reforms favoring firms and economic prosperity. However, it is not guaranteed that the index is properly constructed to measure what it aims to measure, and the placement of certain countries on the index, as well as the results from a number of prev
The migration issue has been a hot topic for decades. However, internal migration has not received as much attention as international migration. Furthermore, the internal migration pattern can differentiate from ethnicities and nativity status, further impacting their social-economic status. This thesis aims to discover the ethnic differences in internal migration patterns and the differences betw
OBJECTIVES: Despite the recent introduction of new peroral drugs as well as neurosurgical methods for Parkinson's disease, treatment of late stage parkinsonian patients remains difficult and many patients become severely handicapped because of fluctuations in their motor status. Injections and infusions of apomorphine has been suggested as an alternative in the treatment of these patients, but the
Sea turtles are known to perform long-distance, oceanic migrations between disparate feeding areas and breeding sites, some of them located on isolated oceanic islands. These migrations demonstrate impressive navigational abilities, but the sensory mechanisms used are still largely unknown. Green turtles breeding at Ascension Island perform long oceanic migrations (>2200 km) between foraging areas
Crowdfunding is an innovative financial measure that is increasingly important in supporting sustainability initiatives. However, little research-based theory has been devoted to crowdfunding in light of the Sustainable Development Goals (SDGs). To bridge this gap, this study utilizes theories of value-attitude-behavior (VAB) model and personality to investigate Korean consumer crowdfunding behavi
Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. To address this challenge, a novel, polymer-based neural probe, with protrusions tailored to the
Objective: To investigate the ability of small-for-gestational-age (SGA) fetuses to develop lacticemia during hypoxia. Methods: Umbilical cord arterial and venous pH, lactate and glucose concentrations were determined in 1777 SGA (<10th percentile) and 14,569 AGA newborns and related to acidemia (pH < mean –2SD). Non-parametric statistics with two-sided p < .05 were considered significant. Results
Antalet barn och unga som upplever könsdysfori har ökat drastiskt under det senaste årtiondet. Unga könsdysforiker har behandlats och behandlas idag med hormoner som kan bromsa pubertetsutvecklingen eller göra att kroppen utvecklas närmare till det könet som den unga identifierar sig som. Könsbe-kräftande hormonbehandlingar till barn har på senare tid väckt ett antal frågor, eftersom behandlingarnThe number of children and adolescents who experience gender dysphoria has increased rapid-ly over the past decade. Gender dysphoria in adolescence may be treated with hormones that either delay the onset of puberty or govern the gender development closer towards the gender that the patient identifies with. Hormonal gender-affirming treatments in children have recently been brought up to discussio
The purpose of this study was to explore how relatives to addicts experience the relation between their own role, health and wellbeing and the support that they have received. It was based on semi-structured interviews with five persons who have or have had family members who are or were abusers of alcohol or drugs. The study used Antonovsky’s concept of Sense of Coherence as well as the notion of
There are as many as 18 theories for the possible functions of the stripes of zebras, one of which is to cool the animal. We performed field experiments and thermographic measurements to investigate whether thermoregulation might work for zebra-striped bodies. A zebra body was modelled by water-filled metal barrels covered with horse, cattle and zebra hides and with various black, white, grey and
Popular Abstract in Swedish Utveckling av AMS-systemet i Lund för detektion av 26Al – med tillämpningar inom växtekologin Den konventionella metoden för att mäta mängden radioaktivt material i ett prov är att detektera strålningen som kommer från provet. Om man vet halveringstiden (den tid det tar för mängen radioaktivt material minska till hälften) så kan man bestämma antalet radioaktiva atomer

Industrial processes currently account for a signifcant share (25–35 %) of the world’s total energy demand and related emissions. During recent years, the amount of low-carbon electricity from renewable energy sources (such as wind and solar) has increased continuously. Tere is therefore an increasing interestin electrifcation of industrial processes in order to achieve long-term decarbonisation g
Studies showing that large-scale public health interventions in early life have lasting economic consequences are still scarce and rarely disclose the mechanisms. Being born in a hospital versus having a traditional birth attendant at home represents the most common early life policy change worldwide. Knowing the consequences of this policy is also important given the ongoing enlargement of matern
Purpose: We report tong-term effects of vagus nerve stimulation (VNS) on epileptiform activity in 15 children, and how these changes are related to activity stage and to clinical effects on seizure reduction, seizure severity (NHS3) and quality of life (QOL). Methods: Initially, and after 3 and 9 months of VNS-treatment, 15 children were investigated with 24 h ambulatory EEG monitoring for spike d
How do you take a reliable measurement of a material whose microstructure is random? When using wave scattering, the answer is often to take an ensemble average (average over time or space). By ensemble averaging we can calculate the average scattered wave and the effective wavenumber. To date, the literature has focused on calculating the effective wavenumber for a plate filled with particles. On
Exploring a wide variety of visualizations of pregnancy and fetuses through 300 years of history, this timely volume offers a fresh look at the influential feminist concept of the "public fetus."Images of pregnant and fetal bodies are today visible everywhere. Through ultrasound screenings at maternity clinics, birth videos on social media platforms, or antiabortion propaganda, visualizations of p
