16. TRANSPARENCY AND THE RESOURCE CURSE IN GHANA: A CASE STUDY Changes since oil discovery
Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionenSammanfattning : When a country has high levels of natural resources, they risk falling prey to the resource curse. Studies show a correlation between high levels of natural resources and corruption as well as lower quality institutions and less democracy. Transparency is a key precondition for accountability and mitigating corruption. LÄS MER
17. IDENTIFICATION OF ENVIRONMENTALLY RELEVANT BENTHIC FORAMINIFERA FROM THE SKAGERRAK FJORDS BY DEEP LEARNING IMAGE MODELING
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Over the several past decades, there has been increasing interest in using foraminifera as environmental indicators for coastal marine environments. As compared to macrofauna, which are currently used in environmental studies, foraminifera offer several distinct advantages as bioindicators, including short generation times, a high number of individuals per small sample volume, hard and durable tests with high preservation potential, and low cost of sample extraction.

18. END-OF-LIFE FOR A QUARRY, WHAT IS THE ENVIRONMENTAL IMPACT?
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Aggregates products are the largest non-energy mining industry in the world, which is the most extracted materials after water. The most prevalent source of aggregates is from quarries, or mines that target the rock itself. LÄS MER
19. Syntax-based Concept Alignment for Machine Translation
Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknikSammanfattning : This thesis presents a syntax-based approach to Concept Alignment (CA), the task of finding semantical correspondences between parts of multilingual parallel texts, with a focus on Machine Translation (MT). Two variants of CA are taken into account: Concept Extraction (CE), whose aim is to identify new concepts by means of mere linguistic comparison, and Concept Propagation (CP), which consists in looking for the translation equivalents of a set of known concepts in a new language.

20. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. LÄS MER
