This thesis investigates whether integrating technical market data with fundamental accounting variables improves the out-of-sample predictability of stock returns in the highly liquid S&P 100 universe. Using an expanding window approach from 2010 to 2024, the study compares the performance of regularized linear (Ridge Regression) and non-linear (Histogram Gradient Boosting) estimators against
The aim of this study was to get a greater understanding of how preschool teachers describe and handle mandatory reporting and suspicions of child maltreatment. The study was based on qualitative semi-structured interviews with six pre-school teachers. Profession theory and a dramaturgical perspective were used in the analysis. The results in the study found that preschool teachers frequently use
Uppsatsen kartlägger anställningsskyddets förändringsprocess och ämnar synliggöra hur samhällsutveckling och normativa grundmönster påverkar rättsutvecklingen. Med hjälp av Christensens teori om rätten som normativa grundmönster i ett normativt fält och Hydéns teori om samhällsutveckling som S- kurvor tolkas, analyseras och diskuteras insamlat material. Genom att belysa relevanta utvecklingstendenThis paper investigates how social development and normative basics patterns affect the process of change in the Swedish employment protection. By using Christensen’s theory of Law as Normative Patterns in a Normative Field and Hydéns theory of Social Development in Terms of S-curves the paper aims to create a profound understanding for the complex interplay between society, norms and legal develo
Sverige, ett av de minst korrupta länderna i världen, har fått återkommande internationell kritik gällande ineffektivitet i svensk mutlagstiftning när det kommer till straffrättsliga sanktioner mot företag som begått mutbrott. Detta på grund av bristen på rättspraxis där företag gjort sig skyldiga till vårdslös finansiering av mutbrott. Kritiken har bland annat kommit från EU-kommissionen då SveriSweden, as one of the least corrupt countries in the world, has been subject to recurrent critique regarding inefficiency in its bribery legislation, especially regarding sanctions against corporates. The reason behind this is due to the lack of case-law when it comes to companies being directly or indirectly responsible for bribery. The European Commission have criticised Sweden due to the fact t
Female drivers operating in the public transport sector are underrepresented in the literature on women’s mobility which largely addresses the fear of crime among female riders. Alternative modes of transport, as well as job opportunities, have nevertheless started to emerge as international and local ride-hailing firms mushroom across the globe in urban cities. The World Bank Group International
This thesis aims to contribute to the growing concept of Digital Financial Inclusion by exploring the challenges that Microfinance Institutes (MFIs) experience to provide financial services to the unbanked population in Bangladesh. Though there is an emergence of digital financial services provided by the commercial banks based on the infrastructural development initiative taken by the Bangladeshi
Inspired by centuries of activists who used creative writing as a tool to encourage reflections and inspire change, this thesis looks at the possibility of poetry to be used as an environmental justice tool. In particular the ability of poetry from Nigeria to engage Dutch people with problems around Shell’s exploitation of the Niger Delta and its people, is investigated. Using decolonial and Criti
The climate change is affecting small island developing states to the amount that the surface of Tuvalu might disappear and the country therefore risk to lose its sovereignty (Pacific Small Island Developing State 2009, p. 10-12). By investigating environmental security through climate displacement this thesis will conduct a case study of Tuvalu. The theory of ecofeminism and intersectionality wil
The global transport industry stands in front of the next big technology shift; the implementation of autonomous vehicles. This shift might remove the physical driver from the truck, increase safety and improve flexibility. This will most likely change the fundamentals of the transportation industry. Autonomous trucks are anticipated to be implemented for short distance transportation in gated are
Skatterätt är ett område som ständigt förändras och påverkas av politiska beslut. Frågan är hur stort utrymme lagstiftaren har när det kommer till att använda den skatterättsliga lagstiftningen för att uppnå politiska mål. Uppsatsen syftar därför till att utreda lagstiftarens utrymme, vilket exemplifieras genom att studera värnskatten. Framställningen kommer utgå från följande frågeställningar: Tax law is an area that is constantly changing and affected by political decisions. The question is how much scope the legislature has when it comes to using tax law to achieve political agendas. The thesis therefore aims to investigate the legislature's scope, exemplified by studying the austerity tax. The exposition will be based on the following questions: 1. What were the motives behind t
År 1998 infördes fridskränkningsbrotten i brottsbalken för att kunna lagföra personer som utsätter sin partner eller annan närstående person för systematiskt och långvarigt våld. Ett av rekvisiten för grov fridskränkning är att offer och förövare ska vara närstående. Bestämmelsen tar främst sikte på personer som har en parrelation utan att vara samboende eller gifta. Syftet med uppsatsen är att kIn 1998, the violation of integrity offences were introduced into The Swedish Penal Code in order to prosecute people who expose their partner or another close person to systematic and long-term violence. One of the necessary requisites in the violation of integrity offences is that victims and perpetrators must have a close relationship. The provision is primarily aimed at people who have an inti
Efforts to reform the public sectors of Zambia have been ongoing since the 1990s with objectives to ensure efficient and high-quality provision of public goods and services to all citizens and battling persistently high levels of poverty. Outcomes have however been mixed at best. This study assesses how reforms to the public sectors of Zambia have been framed in terms of what problem representati
Human pluripotent stem cell-derived in vitro models, combined with advances in high-content live-cell calcium imaging, provide a powerful platform for disease modeling and drug screening. However, most calcium imaging analysis tools have been developed for in vivo applications with suboptimal features for processing data from cultured neurons. Here, we present LUMIN (Live-cell User Module for Imag
Al-Ga-based alloys are promising carriers of renewable energy, which can provide hydrogen by hydrolysis in challenging working environments. Manipulating their performance by different process conditions and comprehending the mechanisms are important for achieving directional design synthesis of alloys and enhancing their practicality. This study presents a novel approach to optimizing the hydroge
A high-resolution integrated bio-chemostratigraphic framework is established for the upper Tremadocian to lower Floian (Lower Ordovician) succession of the North China Block, based on new conodont and carbon isotope (δ13Ccarb) data from the Jiguanshan and Wudingshan sections in Liaoning Province, northeastern China. Thirty conodont species of 19 genera were identified from the two sections. Based
A quantitative understanding of the hydro-environmental factors that influence the occurrence of agricultural drought events would enable more strategic climate change adaptation and drought management plans. Practical drought hazard mapping remains challenging due to possible exclusion of the most pertinent drought drivers, and to the use of inadequate predictive models that cannot describe droug
PurposeThis study aims to investigate how stakeholder cocreation in 3D city mapping initiatives can extend the role of digital urban platforms beyond administrative efficiency toward the negotiation and enhancement of place attractiveness. Drawing on a participatory case study of Trollhättan, Sweden, the paper explores the needs, expectations and aspirations articulated by diverse stakeholder grou
IntroductionAnal squamous cell carcinoma (ASCC) is an HPV-related tumor primarily treated with concurrent chemoradiotherapy (CRT). Salvage surgery is reserved for patients with residual or recurrent disease following CRT, representing a highly selected, high-risk subgroup. Population-based data on outcomes and prognostic factors after salvage surgery are limited. This study aimed to assess overall
Evaluating the repellency of essential oils against Tetranychus urticae requires robust methodologies to detect time-dependent changes in their efficacy, due to differential efficacy, volatility, and sustained effectiveness. This study introduces the Pole-dance bioassay, a novel no-choice method optimized for high-throughput screening of time-dependent repellency, demonstrated through tests on twe
