Environment, social and governance (ESG) ratings are of interest for both investors and researchers for its effect on stock performance. Previous literature has found mixed results with regard to this relationship and few papers are concerned with the volatility of ESG stocks. This paper explores the relationship between ESG scores and idiosyncratic risk. Using monthly news-based, AI generated ESG

This study investigates the performance dynamics of Swedish mutual funds, with a particular focus on the impact of active management, as measured by tracking error, on risk-adjusted returns (Sharpe ratio). The findings reveal a consistent negative correlation between tracking error and Sharpe ratio, indicating that higher levels of active management are associated with poorer performance relative

This paper examines the relationship between female representation on corporate boards and financial performance in Swedish publicly listed companies from 2015 to 2023, excluding the year 2018. This study explores whether a higher proportion of women on boards of directors correlates with improved financial outcomes, measured by Tobin's Q. The empirical strategy employs both pooled Ordinary Le

This study explores why men's employment rates remain relatively stable after childbirth, in contrast to the significant changes often observed in women's employment. Despite progress in gender equality, cultural, economic, and structural factors continue to influence parental work patterns across European countries. Using survey data from the International Social Survey Programme (ISSP),

In today's world, sustainable development has become an important topic. And with the prevalence of the ESG concept, companies and investors have begun to pay more and more attention to ESG performance to measure the company's degree of responsibility and potential for sustainable development.

Studiens syfte var att undersöka hur grammatikundervisningen i kursen Svenska 2 kan se ut. Genom en semistrukturerad intervju studeras sex verksamma svensklärares beskrivning av sitt grammatikinnehåll och sitt resonemang kring innehållsurvalet. Resultatet visar att det finns en samsyn mellan majoriteten av lärarna kring vilket innehåll de inkluderar: fraser, satsdelar och bisatser i kombination meHow can grammar teaching be designed in the course Svenska 2? An interview study about Swedish teachers’ grammar teaching in the course Svenska 2 The purpose of this study was to investigate how grammar teaching can be designed in the course Svenska 2. Through the method of semi structured interview, six Swedish teachers’ description of their selection of grammar content as well as their explanat

The aim of this paper is to examine the effect of maternal and neonatal health on economic growth in low- and middle-income countries between the years 2000-2019. Previous studies indicate that health has a positive effect on economic growth. To examine the effect of maternal and neonatal health on economic growth a multiple regression analysis with panel data has been used. The theoretical framew

This thesis investigates the potential of hydrogen fuel cell (HFC) technology as a sustainable alternative for regional rail transport within the framework of the EU-Rail Flagship Project 6. The thesis focuses on developing a hybrid powertrain model that incorporates both HFC and battery technologies, implementing a rule-based energy management strategy to assess fuel consumption and environmental

The purpose of this research was to examine existing governance arrangements within the Australian federal public service and possible improvements for managing systemic risks at a national level. While there has been greater attention and discussion on systemic risks recently, research on how to govern systemic risk remains in its infancy. Where systemic risk governance is discussed, it is genera

Chronic stress is an escalating global issue that implies significant challenges. The Scandinavian region, including Sweden, faces a substantial obstacle in addressing this problem due to long waiting queues for psychological help. In Sweden, individuals may have to endure a wait of up to 12 weeks, while in Denmark, the waiting period can be as long as 20 weeks. Consequently, there is an urgent ne

The traditional water kettle, while functional, often struggles to adapt to the evolving needs of modern consumers and to integrate seamlessly into contemporary home environments. This thesis reimagines the kettle through a user-centric design approach, addressing limitations in usability and aligning with current and future consumer demands. Through observation, interviews, sketching, prototyping

I detta arbete har en Minimum viable product (MVP) för en applikation utvecklats, som gör det säkrare att avveckla och ta bort endpoints för ett REST API. Tidigare arbete har visat att hanteringen av avvecklingen av endpoints i REST API:er är ett problem, där REST API:er inte följer protokoll för avveckling och borttagning. Applikationen är gjord för att tillhandahålla ett enkelt sätt att övervakaIn this thesis - a Minimum viable product (MVP) for an application aimed at making deprecation and removal of REST API endpoints safer - was developed. Previous work has shown that handling deprecations and removal of endpoints in REST APIs is a problem, with REST APIs not following deprecation-removal protocols nor giving the API consumers the information needed to properly update their software.

What determines whether a change is meaningful or not, and how can it be assessed? Distribution-based methods of assessing meaningful change focuses on statistical significance, while anchor-based methods use other ways of measuring the same construct as the original scale (e.g., PHQ-9), such as expert assessments or other rating scales. This study intends to introduce and validate a novel way of
