Coffee is the most common drink in the world, second only to water. This makes caffeine, the ingredient of coffee known for its wakefulness-promoting effects, one of the most used psychoactive substances. The psychoactive property of caffeine is well-characterized, and entails its interaction with the adenosine receptors, involved in sleep regulation. While studies have shown a deleterious immedia
Avian genomes are typically stable, yet instances of chromosome fissions, fusions and translocations are known across various lineages. For example, multiple sex chromosome translocations have been described in the superfamily Sylvioidea. In this study, we examine the sex chromosomes in two Sylvioidea families, Nicatoridae and Cisticolidae, using whole-genome data. We found sex-linkage of chromoso
Malmö, like many other bigger cities in Europe, faces a double undertaking when facing the challenges the future. Not only must the municipal be able to provide its citizens with welfare and a high standard of living, it must also establish a level of economic growth that allows the city to act as catalyst for the surrounding area. In order to provide the population with welfare and the economy wi
The purpose of this essay was to describe and analyse the tension/conflict between external demands and actual conditions, as experienced (and told in interviews) by employees at two social insurance offices in Scania, concerning their roles in the process of working life rehabilitation. The theoretical starting point is the theory of street-level bureaucrats, as defined by Lipsky. The comprehensi
De straffrättsliga och de socialrättsliga regleringarna löper ofta parallellt i sin ambition att upprätthålla barnets grundläggande rättigheter till en trygg och säker uppväxt. I mötet mellan dess företrädare, i min text representerad av polis och socialtjänst, uppkommer inte sällan svårigheter när dessa regleringar ska tillämpas i en gemensam kontext. Projektet med Barnahus har hittills inte kunnCriminal and socialsecurity regulations are often parallel in their ambition in maintaining the child's basic rights to a safe and secure childhood . In the encounter between representatives for these two legal areas, in my essay exemplified by the police and social services, difficulties often arise when regulations shall be applied in an everyday context . Evaluations of the ”Barnahus”- proj
Abstract Dopamine as a neurotransmitter was discovered in the late 1950s. The dopaminergic system is one of the most well studied neurotransmitter systems in the brain. It is involved in many important functions, such as motor function control; reward, reinforcement, motivation, associative learning, salience information encoding; cognition etc. Disturbances of the dopaminergic system may result
The aim of the study is to analyze how mental illness among young people is represented as a social problem in newspapers. A qualitative method has been utilized to analyze 63 different articles published within the period of 2019-01-01 to 2019-06-30 in three of Sweden’s largest newspapers. Additionally, the theoretical framework that has been applied is the theory of claims-making. Furthermore, i
Due to the restrictions of the corona pandemic the counsellors at the Swedish Child and Adolescent Psychiatric Services had to suddenly transition to online counselling. The purpose of this study was therefore to examine how social workers, i.e. psychiatry counsellors, describe and experience online counselling and the impact it has on the interaction. The method chosen in this study was qualitati
Since August 2021 Swedish social services have had a special responsibility to work for perpetrators of violence to change their behavior, but little research has examined aspiring social workers’ interest in working with the target group. This quantitative study has aimed to understand social work students’ interests, knowledge about, and how comfortable they are in working with perpetrators of v
In recent years the unprecedented spread of disinformation on online platforms, along with declining trust in government, journalism, and institutions, has consequently led the EU to regard disinformation as an urgent threat to democracy. To address the threat the EU decided in 2022 on the groundbreaking Digital Services Act (DSA) legislation, targeting digital platforms. However, the complexity o
The purpose of this paper is to explore the extent to which young Chinese consumers are making conspicuous consumption of fashion products. With China's increasingly rapid economic development, the income and consumption levels of the Chinese middle class are rising. Younger people, thanks to higher household income levels, also have more wealth at their disposal. Thus young Chinese are alloca
The construction and demolition industry are annually responsible for 40% of the total amount of waste generated in Sweden. The problem facing the industry is that a very large portion of the waste is disposed of in landfills, and only a very small portion is recycled and reused. The purpose of this study is to investigate how the construction industry can become more circular and sustainable over
In this work simulations of the LIBAF Pelletron were performed to gain insight into the parameters that govern the machine operation and control. Three simulation packages: COMSOL, WARP and TURTLE/TRANSPORT were employed, and cross-validation of these software packages was performed by test-case simulations. The major components of the Pelletron were simulated on a individual basis to ensure their
Microfluidic devices have so far not seen widespread use, even though they could potentially be cheaper, better and faster than traditional methods. A possible reason for this is the lack of a middle step between one-of-a-kind experimental devices and cheap mass produced devices. With ongoing improvements in resolution it is starting to look possible that 3D-printing will fill this role. This the
Svenska elitidrottares mentala träningsvanor undersöktes genom en webbaserad enkätundersökning som besvarades av 47 aktiva idrottare (28 män, 19 kvinnor, ålder 16-37, M=25) inom fotboll, friidrott, handboll, ishockey och tennis. Studien visade att svenska elitidrottare i genomsnitt ägnar 41 minuter i veckan åt olika mentala träningsformer, dock med stor individuell spridning. Mängden mental träninThis paper aimed to study to what extent Swedish elite athletes engage themselves in psychological skills training (PST).

This thesis aims at comparing the differences between Chinese welfare system and Swedish welfare system in respects of maternity insurance, parental leave and childcare. The reason comparing welfare system in these specific aspects is because they have intense relations with the mothers’ and children’s benefits. They also influence the mothers’ will of pregnancy. Selecting these two countries as t
How to define Private Military Companies is an issue, which due to PMC’s explosive growth during the last 30 years has become increasingly relevant. But how do you define the PMC personnel that take a direct part in combat situations? Through a singularly juridical aspect, based on interpretations of the Geneva Conventions I try to answer this problem. This essay first tries to define the PMC
Linné glacier has retreated approximately 1.8 km since 1936 and 1 km between 1995 and 2019. Linné glacier is following the same trend as other glaciers around Svalbard. Linné glacier is a well-monitored glacier with a time series of air temperature, incoming solar radiation and snow height data since 2003. Annual recordings of the glacier margin from 2007, allows for an accurate reconstruction of
The aim of this study was to examine the Swedish prostitution law that makes it illegal to buy sexual services but legal to sell them. More specifically the aim was to find out the perceptions and attitudes of social workers in regards to the Sex Purchase Act which was enacted in 1999 and was first of its kind in the world. We carried out qualitative interviews in three larger Swedish municipaliti
