This thesis investigates how algorithmically driven features of social media platforms, specifi cally personalized recommendations, infinite scroll, auto-play and push notifications affect university students’ emotional states and academic performance. Drawing on the Stimulus - Organism - Response (SOR) framework, the study explores how these features act as digital stimuli that provoke cognitive

This thesis explores the effect on neonatal, post-neonatal, and child mortality of being a motherless child and the interaction this situation had with socio-economic status and gender in Sweden during the period 1790-1910. Using a longitudinal, individual level, database (SwedPop), covering large parts of the Swedish population, together with a Cox proportional hazards model, this study finds tha

Understanding how plants allocate time between the green-up and senescence phases within a growing season is critical for assessing vegetation responses to environmental change. This thesis investigates the spatiotemporal patterns of the time allocation fraction, defined as the ratio of green-up duration to senescence duration (RGS), across the Tibetan Plateau from 1982 to 2018. Phenological metri

This research analyses the communication strategies of the Israeli Defence Forces (IDF) and Hamas’ Al-Qassam Brigades on Telegram following the October 7th, 2023, attack. Focusing on 40 images and videos posted between October and December 2023, it investigates how visual content is used to perform violence, shape narratives, and legitimise actions. The study adopts a qualitative, social construct

Extreme heat is not neutral. In Athens, the dense urban environment and harsh summer climate disproportionately impact the socio-economically marginalized. This research bridges the gap between climate data and human experience by uniting geospatial and qualitative survey data regarding heatwaves in Athens Municipality, with urban heat island research, vulnerability theory and climate justice. Sat

This thesis examines how individuals form and enact political vegan identity through everyday practice, and the role digital media platforms play in mediating that process. Drawing on 12 semi-structured interviews with vegan participants across 4 groups defined by age and length of vegan practice – New Sprouts, Early Roots, Late Bloomers, and The Oakes – the study traces the specific processes thr

Indigenous Peoples' Lands (IPL) cover approximately one quarter of the Earth’s land surface and play a potentially significant role in sustaining terrestrial moisture flows (TMF). Yet, understanding of how they contribute to regional hydrological cycles remains limited. Building on a global-scale study suggesting a buffering role of IPL in West African precipitation during the dry season, this

After several years of broad support for the European Green Deal (EGD), a significant number of communities and politicians are calling on the EU and Member States to slow down its green measures and focus on ‘other’ crises, most notably the cost-of-living crisis.This White Paper argues that environmental, social and economic crises can’t be looked at in isolation. And that addressing today’s ‘pol

Southern Africa is a global hotspot for hydrometeorological risk, with intensifying droughts and floods increasingly disrupting livelihoods, ecosystems, and infrastructure. This study presents a systematic bibliometric and scientometric synthesis of 1481 peer-reviewed publications on drought and flood hazards published between 2000 and 2024 across the Southern African Development Community. Using

Standard-setting is undoubtedly beneficial to society. Its foremost advantage is that it ensures interoperability between products and thereby increases consumer welfare. Standardization covers a wide range of activities, but for the purpose of this thesis it can be defined as activities that set technical specifications that seek to provide a common design for a product or process. Standards thus

This thesis addresses the right to education and its implementation. It briefly assesses the right to education while focussing on the right to primary education. The implementation of human rights as stated in international instruments can meet with hindrance in the form of cultural relativist arguments as well as resistance on pragmatic grounds. The case study carried out in Tanzania aims at ass

The objective for all businesses is to maximize long-term shareholder value by optimizing all activities and utilization of resources. To comply with this objective, all functions need to be business driven; develop and maintain internal activities and structures to align with market requirements. ST-Ericsson is a 50/50 joint venture; created by bringing together ST-NXP Wireless (ST-NXP) and Erics

Lignocellulosic biomass is a promising alternative fuel source which can promote energy security, reduce greenhouse gas emissions, and minimize fuel consumption when paired with advanced combustion strategies. Pyrolysis is used to convert lignocellulosic biomass into a complex mixture of phenolic-rich species that can be used in a transportation fuel. Anisole (or methoxybenzene) can be used as a s

Modelling is an alternative solution to reduce the cost of water quality monitoring. Commonly, concentration of pollutants is estimated based on limited sampling information. Concentration of ions in rivers can be estimated using modelling strategies that involve statistics and artificial intelligence as well as the understanding of physical processes. Therefore, the performance of feedforward neu

Dopamine (DA) neurons derived from human embryonic stem cells (hESCs) are a promising unlimited source of cells for cell replacement therapy in Parkinson's disease (PD). A number of studies have demonstrated functionality of DA neurons originating from hESCs when grafted to the striatum of rodent and non-human primate models of PD. However, several questions remain in regard to their axonal outgro

Mercury was measured onboard the IAGOS-CARIBIC passenger aircraft from May 2005 until February 2016 during near monthly sequences of mostly four intercontinental flights from Germany to destinations in North and South America, Africa and South and East Asia. Most of these mercury data were obtained using an internal default signal integration procedure of the Tekran instrument but since April 2014

Abstract: This article summarises the information that should be provided to women and referring physicians about breast ultrasound (US). After explaining the physical principles, technical procedure and safety of US, information is given about its ability to make a correct diagnosis, depending on the setting in which it is applied. The following definite indications for breast US in female subjec
