1. 1. The Sound of Skepticism Analyzing Climate Change Denial in Swedish Podcasts and YouTube Channels

   Kandidat-uppsats, Göteborgs universitet / / Institutionen för sociologi och arbetsvetenskap

   Författare :Victoria Vallström; [2024-02-14]
   Nyckelord :denialism; climate skepticism; social movements; countermovements; digital media; digital data; computational grounded theory; topic modeling; computational text analysis;

   Sammanfattning : This study explores Sweden's climate change denial by analyzing the spoken-word discourse of its countermovement, focusing on digital media content from Swedish parliament member Elsa Widding with an aim to provide empirical insights into the discourse of Sweden's Climate Change Countermovement (CCCM). Questions guiding this study are: What are the most prevalent topics and themes related to climate change denial and skepticism? How do they align with established categories of climate change denial, shaping the overall narrative? What mobilizing ideas and meanings are present, how are they shaped, and how do they contribute to the movement's goals? The material consists of Elsa Widding's complete audio-based "movement texts'' from 2019-2023, including YouTube content, podcasts, and appearances on Riks, totaling over 2000 minutes of audio transcribed into text via AI technology.

3. 2. Network Connectedness in Financial Markets

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

   Författare :Andrea Marcolini; [2024]
   Nyckelord :Systemic risk modeling; US REITs connectedness; S P 500 connectedness; Returns and realized volatilities prediction;

   Sammanfattning : This paper is a collection of two different theses discussing the prediction of the returns and volatilities of the S&P 500 constituents and of US Real Estate Investment Trusts (REITs) by analyzing their centrality within the financial market network. Both empirical works summarize the relevant financial and network literature, demonstrating how modeling stock connectedness within financial markets makes it possible to create returns and volatility predictors, improving investors' portfolio allocations and achieved investment Sharpe ratios.

4. 3. Parabolic equation models simulating LoS MIMO conditions

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Författare :Zarafshan Carneil; [2023]
   Nyckelord :MIMO; channel capacity; phase difference; MIMO phase;

   Sammanfattning : This thesis explores and develops a simulation model for Line of Sight(LoS) Multiple-Input Multiple-Output (MIMO) systems in complex environments. The focus will be on implementing a 2 × 2-MIMO system in order to study phase differences of the received signals. LÄS MER

5. 4. Who fills the income protection gap? : An empirical analysis of the development of complementary unemployment insurance in Sweden  

   Master-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

   Författare :Karin Meiton; [2023]
   Nyckelord :unemployment insurance; unemployment risk; income protection; occupational welfare; Sweden; social policy analysis.;

   Sammanfattning : The Swedish welfare state is often conceived as a universal and encompassing welfare state. However, research has shown significant contractions of coverage and benefit levels in several Swedish welfare programs in the last 20 years. One such program is the unemployment insurance. LÄS MER

7. 5. Water quality monitoring with Sentinel 2 in small watercourses : Investigating the measurability of phosphorus using proxy data

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Caroline Morin; [2023]
   Nyckelord :Optical remote sensing; Sentinel 2; Phosphorus; Total suspended matter; Turbidity;

   Sammanfattning : Inland water has for a long time showed vast stress due to eutrophication, mainly caused by increased levels of phosphorus. Applying remote sensing as a tool for monitoring water parameters has long been used. LÄS MER
