Den som tittar noggrant upptäcker ofta hur samma djur- eller växtart kan ha varierande former, till exempel utseenden och färger. Bland det vanligaste fenomenet är tydliga könsskillnader mellan hane och hona, eller sexuell dimorfism där hanen vanligtvis är större, har ornament eller är mer färgglad jämfört med honor. Detta går även att observera bland insekter där honor och hanar varierar i färg oSex-limited polymorphism is an interesting evolutionary phenomenon, which is widespread across organisms. Studying ultimate mechanisms that result in the evolution of sex-limited polymorphism can provide a window into how natural and/or sexual selection can result in the evolution of complex phenotypes. Here, I use butterflies from the tribe Polyommatini to study the evolutionary mode and tempo of

In the past decade, problematic school absenteeism has become a well-known concept in society and research. This study aims to research professionals’ perspectives on problematic school absences in elementary school and high school, and their alternative solutions and thoughts about preventative work. The study is conducted by several semi-structured interviews with six professionals who work or h

Bakgrund: Tidigare forskning har visat på låg kunskap gällande fertilitet, i synnerhet hos unga män. Medelåldern för förstagångsföräldrar ökar och man kan se att personer senarelägger barnafödandet till förmån för utbildning och karriär. Med bakgrund av detta har en internationell expertgrupp utvecklat en poster med fertilitetsrelaterad information: “Vill du ha barn i framtiden? Nio saker som kan

Syftet med denna studie var att undersöka om de fyra dimensionerna av identitetsledarskap (prototypikalitet, avancemang, entreprenörskap och direktörskap) predicerade olika former av socialt stöd (upplevt stöd från närmaste chef och stöd från medarbetare) samt social gemenskap på arbetsplatsen. Insamlingen av data utfördes i Sverige i form av en digital enkätundersökning som besvarades av personerThe purpose of this study was to examine if the four dimensions of identity leadership (prototypicality, advancement, entrepreneurship and impresarioship) could predict different forms of social support (perceived supervisorial support and collegial support) as well as social community in the workplace. The data was collected in Sweden through a digital survey which was answered by people who had

Bakgrund: Aktivitet och delaktighet är viktigt för hälsa och välbefinnande. En funktionsnedsättning kan medföra inskränkt delaktighet i fritidsaktiviteter. Fritidshjälpmedlet Joëlette, kan beskrivas som en en-hjulad rullstol med två handtag fram och bak. Joëlette används för att möjliggöra för personer med funktionsnedsättning att delta i turer i naturen. Bara ett fåtal tidigare studier finnsBackground: Activity and participation are important for health and wellbeing. A disability may lead to limited participation in leisure activities. The assistive device Joëlette can be described as a one-wheeled wheelchair with two handles at the front and back. Joëlette is used to enable persons with disabilities to participate in tours in nature. Only a few previous studies exist on similar as

This thesis investigates the inflationary impact of the European Electricity Market on its member countries, including the EU28, Norway, and Switzerland, from 2003 to 2019. The research question particularly focuses on whether this market impacts the level of inflation in its net exporting member countries. Utilising two panel data regression models, we explore the market's impact on the rate

Refusal to work is a term that falls under misconduct concerning termination and dismissal. The employee and the employer each have obligations due to the employment relationship. Refusal to work can be a breach of the duty of loyalty and thereby a breach of the employment contract. There is no clear definition of refusal to work in Swedish legislation, why this essay aims to investigate the meani

As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. In this study the frequentist and Bayesian framework is tested against each other based on three

In 2017 the Swedish government issued an official report containing proposed changes to the compulsory care legislation to strengthen the child rights perspective and provide extended knowledge to the workers within psychiatry. The aim of this study was therefore to examine the reasoning regarding the proposed changes in the comment letters following the official report of the Swedish government:

The results of our

Ett av de viktigaste målen inom experimentell fysik, om inte det viktigaste, är att utföra precisa mätningar för att nå bästa möjliga resultat. Inom högenergifysik görs mätningarna med hjälp av specialbyggda detektorer som bland annat finns vid världens största partikelaccelerator the Large Hadron Collider (LHC). Vid LHC utförs flera experiment och ett av dessa är A Large Ion Collider Experiment This thesis deals with the physics performance of an approved inner tracker upgrade of the ALICE experiment involving a novel and ultra-thin silicon detector with a cylindrical geometry. During the thesis work, a method was developed in simulations to induce distortions to the detector’s geometry, and the resulting loss in physics performance was evaluated. A strategy was also developed to be able

Our study aimed to, through a qualitative content analysis, understand how violence manifests among young women aged 16-25 in their romantic relationships, as well as how violence affects their social lives. By listening to six podcasts, watching three short film clips, and reading three written texts, we have gained insights into personal stories from young women's own experiences of violence

Subsequently, the essay will address the purpose by utilizing the presented material. The equestrian world has pre

Möjligheten att beviljas uppehållstillstånd på grund av anknytning har sedan länge varit möjligt enligt det svenska regelverket. Systemets baksida är att den anhöriges uppehållstillstånd är beroende av anknytningspersonen varför en inlåsningseffekt kan uppstå vid våldsutsatthet. Som i ett försök att mildra reg-lernas negativa följder har lagstiftaren infört en skyddsregel som möjliggör att fortsatThe possibility of being granted a residence permit on the basis of affiliation has long been possible under Swedish legislation. The downside of the sys-tem is that the family member's residence permit is dependent on the person to which he/she are affiliated with, so a lock-in effect can arise in cases of vio-lence. In an attempt to mitigate the negative consequences of the regulation, the l

The purpose of this study was to examine drug availability and social risk- and safety factors regarding adolescents' drug use. The method used for this study was a survey, with 140 students from Helsingborg's high schools as respondents, allowing a quantitative analysis. The theory used in this study was Albert Bandura's social learning theory. Previous research shows that there are s

Syftet med uppsatsen var att studera lycka och tillit till rättsväsendet. När jag införde en politisk nationalistisk dimension i min modell fick jag andra resultat än aktuell forskning. I senaste NTU 2023 uppvisar exempelvis kvinnor högre tillit till rättsväsendet än män. Relationen blev den omvända i min studie. När variabeln nationell tilltro togs med i modellen ökade denna tendens ytterligare,
