The paper examines the extent to which role-based access control is used within organizations to control and assign access rights to users. Furthermore, this paper investigates whether organizations are aware of security risks that arise when users are assigned too many or incorrect access rights and the steps they take to reduce the problem. The survey was conducted through the collection of qual

Plasmodium parasites are present in a wide range of host species, some of which tend to be more susceptible than others, potentially as an outcome of evolved tolerance or resistance. Common starlings seem to cope with malaria infection while common crossbills are more susceptible to the same infections. That raises the question if the parasites rely on the same molecular mechanisms regardless of h

Mechanical changes within cells and viruses have been shown to be of great importance for various mechano-signaling processes. In phage and herpesviruses, strong confinement of double-stranded DNA inside the capsid generates tens of atmospheres of pressure. This confinement leads to electrostatic sliding friction between neighboring DNA strands. This affects the mobility of the encapsidated genome

Microplastics have recently become a growing environmental issue, whereas the smaller fractions, nanoplastics, have received less attention. Due to their small size, nanoplastics may affect organisms differently and potentially more severely than larger microplastics. In natural environments nanoplastics also interact with organic material and form larger aggregates, which may, potentially, reduce

Animal groups vary in their collective order (or state), forming disordered swarms to highly polarized groups. One explanation for this variation is that individuals face differential benefits or costs depending on the group’s order, but empirical evidence for this is lacking. Here we show that in three-spined sticklebacks (Gasterosteus aculeatus), fish that are first to respond to an ephemeral fo

We describe two novel flagellates isolated from soil, Regin rotiferus and Otto terricolus, genera et species novae, which we cultivated and characterized by light and transmission electron microscopy and by 18S rDNA sequence analysis. Both strains exhibit the key characteristic structural feature of Bicosoecida; i.e. the L-shaped cytostomal root system with an x-fiber, used for feeding. Otto terri

This paper focuses on the specific problems in the labour and social security legislation as it relates to crowdworkers in the digitalised new economy, analysing their place in labour market, and especially in the collective agreements which are the standard means of regulating working conditions in the Nordic model. Sweden has a binary system where a performing party is as either an employee or s

After detecting the customer needs it is possible to define functional requirements and set the design goal. The latter is represented by a target defined specification list of requirements. Such defined functions can serve as a basis for the concept, created by means of the morphological matrix. The optimum solution is selected after a rough assessment of results from the technical and economic p

Author: Malin Glimhed Title: Not just a picture (translated title) A qualitative study about the way the art therapists work with children. Supervisor: Staffan Blomberg The aim of this study is to give knowledge to the role of painting in art therapy with a child.

The aim of this paper is to characterize the daily price fundamentals of European Union Allowances (EUAs) traded in the EU Emissions Trading Scheme (ETS) during the period September 2005 - February 2010. We use GARCH model in order to account for changes in volatility. We split our analysis into two periods according to the two phases of the ETS. We disregard the period 02.04.2007 – 11.08.2008, wh

The purpose of this essay was to describe and compare two different investigation methods of foster homes and if there is any connection between the investigation method and a breakdown. The two methods we have been examined are the Kälvestens-method and the PRIDE-method. The main questions have been: · How common is breakdowns in foster homes, national and in respective municipality? · How the Kä

American studies have shown that sexual abuse allegations within the family during divorce cases occur in the USA. No previous studies regarding this matter has been undertaken in Sweden. I therefore decided to investigate the occurrence of sexual abuse allegations in Sweden and more specifically in Helsingborg. My purpose was to find out the frequency of sexual abuse allegations within families r

In this studie I looked deep into help to-self-help books that treat the subject; women's burnout in working life. Through discourse analysis I tried to discover different discourses and patterns in the writers texts. My purpose with this study was to try to understand how writers to help-to-self help books describes women in relation to women's burnout in working life from a gender perspe
