This study seeks to explore the identity and cultural belonging of second-generation immigrants. The purpose is to examine the view that second-generation immigrants have on these two aspects and the impact it has on creating their identity. The study is conducted through qualitative semi-structured interviews held with six individuals who qualify as second-generation immigrants. The individuals c

Within months, everything changed in the autumn of 2024. Northvolt, once the defining symbol of Sweden’s green transition, suddenly found itself at the centre of one of the country’s most serious economic crises in decades. What had been a modern, sustainable fairytale of rapid growth and global ambition turned into a question of survival, ownership, and maintaining the Northvolt name. It is now

This thesis presents a scoping review of academic literature on the intersection of religion, spirituality, and Indigenous worldviews with climate change adaptation. While adaptation research has traditionally emphasised technical, institutional, and financial dimensions, the cultural and spiritual dimensions shaping community responses remain underexplored. To address this gap, the review systema

The rapid digital transformation of education, driven by the widespread adoption of smart devices and online platforms, has ushered in the era of smart education. While this shift enhances learning experiences, it also introduces significant cybersecurity risks that threaten the confidentiality, integrity, and availability of educational resources, student data, and institutional systems. This sur

Previous research in various educational areas has shown that literary texts have much to contribute through offering perspectives, contexts, and ways of presenting content. The present study has a particular focus on science education. The purpose of science education is under debate, and research as well as large-scale frameworks such as PISA increasingly highlight student agency and action comp

This paper examines firefighter exposure to emissions during actual firefighting in building scenarios. The focus is on actual exposure, not small-scale lab tests, to identify research gaps in light of the International Agency for Research on Cancer (IARC) classification of firefighting as an occupation with a heightened risk for certain types of cancer. The work is based on a systematic literatur

A measurement of off-shell Higgs boson production in the H∗ → ZZ → 4ℓ decay channel is presented. The measurement uses 140 fb−1 of proton–proton collisions at √s = 13 TeV collected by the ATLAS detector at the Large Hadron Collider and supersedes the previous result in this decay channel using the same dataset. The data analysis is performed using a neural simulation-based inference method, which

A search for decays of the Higgs boson into a Z boson and a light resonance, with a mass of 0.5–3.5 GeV, is performed using the full 140 fb−1 dataset of 13 TeV proton–proton collisions recorded by the ATLAS detector during LHC Run 2. Leptonic decays of the Z boson and hadronic decays of the light resonance are considered. The resonance can be interpreted as a J/ψ or ηc meson, an axion-like particl

A search is presented for a heavy scalar (H) or pseudo-scalar (A) predicted by the two-Higgs-doublet models, where the H/A is produced in association with a top-quark pair (tt¯H/A), and with the H/A decaying into a tt¯ pair. The full LHC Run 2 proton–proton collision data collected by the ATLAS experiment is used, corresponding to an integrated luminosity of 139fb-1. Events are selected requiring

The femtoscopic study of pairs of identical pions is particularly suited to investigate the effective source function of particle emission, due to the resulting Bose–Einstein correlation signal. In small collision systems at the LHC, pp in particular, the majority of the pions are produced in resonance decays, which significantly affect the profile and size of the source. In this work, we explicit

Differential measurements of Higgs boson production in the τ-lepton-pair decay channel are presented in the gluon fusion, vector-boson fusion (VBF), VH and tt¯H associated production modes, with particular focus on the VBF production mode. The data used to perform the measurements correspond to 140 fb−1 of proton-proton collisions collected by the ATLAS experiment at the LHC. Two methods are used

Aims. We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star on a relatively long orbit of 18.26 days, by combining new photometric and spectroscopic observations. Methods. We analyzed new space-based photometry from TESS and CHEOPS, as well as 61 radial velocity measurements from HARPS-N. We performed individu

Purpose: To examine whether generative AI adoption influences analyst forecast error and bias, and whether the relationship differs across firms with different characteristics. Methodology: The study applies a quantitative panel-data approach using pooled OLS and firm fixed effects regressions. Interaction models are used to examine whether firm size, segment complexity, intangible intensity an

The extreme volatility and pronounced non-stationarity of cryptocurrency prices challenge traditional time-series models and motivate the use of deep learning. This thesis addresses three focused research questions: (i) Do gated recurrent neural networks (GRNNs) produce more accurate one-day-ahead Bitcoin return predictions than feedforward neural networks and linear benchmarks? (ii) Can a GRNN ba

This thesis explores the regulatory friction that surfaces when the General Data Protection Regulation (GDPR) and the Artificial Intelligence Act (AI Act) apply side by side to high‑risk AI systems. It homes in on three connected problems. First, there is a procedural overlap between the Data Protection Impact Assessment (DPIA) and the Fundamental Rights Impact Assessment (FRIA). Second, a normati
