Colonization and migration have a crucial effect on patterns of biodiversity, with disease predicted to play an important role in these processes. However, evidence of the effect of pathogens on broad patterns of colonization and migration is limited. Here, using phylogenetic analyses of 1,311 species of Afro-Palaearctic songbirds, we show that colonization events from regions of high (sub-Saharan
The dynamical processes associated with electric field manipulation of the polarization in a ferroelectric remain largely unknown but fundamentally determine the speed and functionality of ferroelectric materials and devices. Here we apply subpicosecond duration, single-cycle terahertz pulses as an ultrafast electric field bias to prototypical BaTiO3 ferroelectric thin films with the atomic-scale
Background: Persons with clinical onset of Alzheimer’s disease (AD) before 65 years of age are diagnosed with early-onset AD (EOAD). The prevalence of EOAD is low, but varies among studies from 6% to 16%. Most individuals with EOAD are still working, have an active social life, and might have children living at home. Therefore, the consequences of being diagnosed early with a disease that implies
The effect of the blend ratio of water-insoluble ethyl cellulose (EC) and water-soluble hydroxypropyl cellulose (HPC-LF), on the properties of sprayed films and on the drug release mechanism of formulations coated with the material was investigated. When the original HPC-LF content exceeded 22%, both the amount of HPC-LF leached out and the water permeability of the films increased drastically whe
Purpose. To investigate how individualised occupation-based interventions with commonly available everyday technology (ET) can compensate for perceived difficulties with daily life tasks after an aquired brain injury (ABI) and improve satisfaction with occupational performance. Method. This intervention study was designed as a multiple case study according to Yin. Ten men and women with an ABI (tr
Over the last decades methods of vestibular rehabilitation to enhance adaptation to vestibular loss, habituation to changing sensory conditions, and sensory reweighting in the compensation process have been developed. However, the use of these techniques still depends to a large part on the educational background of the therapist. Individualized assessment of deficits and specific therapeutic prog
We consider stochastic population processes (Markov jump processes) that develop as consequence of the occurrence of randon events at random time-inervals. The population is divided into sub-populations or compartments. The events occur at rates that depend linearly with the number of individuals in the different described compartments. The dynamics is presented in terms of a Kolmogorov Forward Eq
Partial migration is a common phenomenon among many animals and occurs in many types of ecosystems. Understanding the mechanisms behind partial migration is of major importance for the understanding of population dynamics and, eventually, ecosystem processes. We studied the effects of food availability on the seasonal partial migration of cyprinid fish from a lake to connected streams during winte
We analyze the frequency and nature by which new firms are acquired by established businesses. Acquisitions are often considered to reflect a technology transfer process and to also constitute one way in which a "symbiosis" between new technology-based firms (NTBFs) and established businesses is realized. Using a micro-level dataset for Sweden in which we follow new entrants up to 18 years after e
Sverige blev medlem i den Europeiska unionen 1995. En viktig del i samarbetet är upprättandet av den inre marknaden. EG-fördraget är garanten för att fri rörlighet för varor, tjänster, kapital och personer ska vara möjlig mellan medlemsstaterna. Några hinder för den fria rörligheten får inte förekomma på dessa områden. EG-domstolen ser till att EG-fördragets bestämmelser efterlevs av medlemsstater
A case study on the phenomenological obstacles for adjusting lifestyle to ecological awareness. The data is obtained mainly through deep interview, backed by preparatory research including chiefly participant observation, informal and semi structured interviews. The findings have been connected to relevant concepts and theories in a process of grounded theory. The fatigue, fears and doubts felt by
Bytesrätten har utvecklats i samklang med den svenska bostadspolitiken. Under tidigt 1900-tal fanns det en stark liberal inställning till relationen mellan hyresgäster och hyresvärdar. I 1907 års nyttjanderättslag (1907:36), NyttjL, gällde grundläggande avtalsrättsliga principer. Hyresgäster fick enbart säga upp kontrakt om hyresvärden nekade dem överlåtelse av kontraktet utan skälig anledning. I The right to barter a rented apartment has developed in harmony with the Swedish housing policy. During the early twentieth century a strong liberal doctrine dominated the relationship between tenants and landlords. The usufruct law (nyttjanderättslagen) from 1907, was based on contractual principles. Contracts could be for as long as 25 years in the towns and tenants were only allowed to terminat
Problem discussion: Long-term supplier relationships have become more common. Hence, supplier evaluation is a critical activity for many companies. However, making a relevant supplier evaluation is time consuming. Therefore, it is important to decide which of the suppliers to put an extra effort on. Should all suppliers be evaluated in the same way? Previous, focus has been on purchasing of direct
Jag har analyserat huvud- och spårelementkoncentrationer i plagioklas från en norit-anortositintrusion, Älgön, Hakefjorden vid Sveriges västkust med syfte att fastställa intrusionens magmatiska ursprung, magmans utveckling och dess transport upp genom jordskorpan. Megakrister av plagioklas i anortositen har en homogen fördelning med avseende på huvud- och spårelement medan plagioklas-megakrister i
Kurdish women’s resistance, self-preservation, reclamation of their language, surviving, and living undeniably as a Kurdish woman is to defy and resist colonial violence. The existence of Kurdish women as Indigenous peoples across four different colonial powers is within itself an act of resistance. This study illuminates the significance of the colonial violence against Kurdish women and their ev
Användningen av Artificiell Intelligens har ökat de senaste åren och många arbetsgivare väljer att integrera AI i rekryteringsprocessen i syfte att vara kostnads- och tidseffektiva. Men användningen av AI medför betydande nackdelar såsom oavsiktlig diskriminering. Uppsatsen syftar till att undersöka den rättsliga reglering inom diskrimineringsrätten när AI används i rekryteringsprocesser. Vidare k
Recently, new spectroscopic techniques have been developed such as photocurrent detected two-dimensional spectroscopy [1], which measure the response from a sample that is excited by a high intensity laser pulses. The responses are linear and nonlinear signals that have very different amplitudes; the linear signal can be from 103 to 105 times larger than the nonlinear signal. These two signals hav
Sales and Operations Planning, S&OP, is a cross-functional, collaborative business manage- ment process where the goal is to balance demand and supply through an operational plan, aligned with the strategy of the company. Alfa Laval, a Swedish manufacturer founded 1883, has during the last year implemented Sales and Operations Planning at their business unit Gasketed Plate Heat Exchangers. In
Syfte: Studien ämnar undersöka hur skånska mikro- och småföretag finansierar sin verksamhet och om de agerar i enlighet med pecking-order teorin. Detta görs med syftet att fylla kunskapsgapet och öka förståelsen kring finansieringsstrategier och finansieringsalternativ hos mikro- och småföretag. Det är en förhoppning att studien skall bidra med ny kunskap samt inspirera till framtida studier inom Purpose: The study aims to examine how micro and small enterprises choose to finance their activities and if they act in accordance with the pecking-order theory.
