Assessment of operational changes in the maritime transport with the introduction of the EU ETS
No full textWhile the European Union is implementing new environmental measures, this thesis explores the segment-specific impacts of the European Union Emissions Trading System (EU ETS) on the shipping industry. By examining data from the Automatic Identification System, this study details the policy's short-term environmental effects across different shipping segments, focusing on the first quarter following its implementation in January 2024. To do so, our observations are mainly based on visual representation of the data and on difference-in-differences analysis. The most important observation we make is that the EU ETS has been responsible for a decrease per voyage of 15.38 tonnes of CO2 equivalent since its introduction. Furthermore, we demonstrate that this impact has been larger on small-sized vessels as they show more significant reduction in speed and pollution levels. Further we show that the market is very sensitive to carbon allowances prices as, since 2024, voyages display a reduction of 15.16 tonnes of CO2 equivalent per euro increase in the prices of allowances, meaning that policymakers can optimize the efficiency of the measure by monitoring prices. Finally, we looked for carbon leakage by observing the evolution of emissions in ports situated close the European Economic Area but found no significant evidence of rerouting. However, all these observations are based only on the initial response of the sector to the new measure. Therefore, it is important to continue measuring the effectiveness of the system in the upcoming months. This assessment will help estimate its long-term influence and adjust the system if the results deviate from the objectives of the European Union concerning environmental protection
Morphological evolution of birds recently introduced to islands: patterns of diversification
No full textEvolution was originally considered to be observable only over geological time scales. It has recently become apparent that evolutionary changes can be detected over contemporary time periods. Exotic species often experience intense selection, making them good model systems for investigating evolutionary changes over contemporary time. We often know details of the introductions, such as exact time, location of the source population, founding propagule size, and establishment history. These details allow us to formulate hypotheses concerning the evolutionary changes expected in these species' exotic ranges.
I examined contemporary morphological evolution of passerine birds introduced to islands. Passerine birds have been introduced to many islands world-wide, making them conducive for examining patterns of insular evolution. In chapters one and two, I evaluated whether these species conform to the Island Rule, an ecogeographic rule based on the study of native insular species. It states that, on islands, small species should increase in body size while large species should decrease body size. All of the species I studied are small, therefore they were expected to increase in body size. I found equivocal results concerning the Island Rule. In chapter one, I found that the great kiskadee (Pitangus sulphuratus) follows the Island Rule, as it is larger in its exotic island range than in the native source range. However, in chapter two, I found no clear Island Rule pattern examining 39 insular populations. However, I did find a clear pattern of decrease in wing length and increase in tail length. Although these populations may not be following an overall Island Rule pattern, they are still adapting to their exotic environments. In chapter three, I evaluated among-island diversification of six passerine species introduced to the Hawaiian archipelago. Five of these six species show some morphological differentiation between islands, and at least some of this differentiation cannot be accounted for by genetic drift.
The results of this dissertation provide further support for the idea that evolutionary divergence can happen over contemporary time scales. The passerine bird populations examined in these chapters have adapted to local conditions, giving us insights into the genesis of evolutionary diversity.Ph.D.Includes bibliographical referencesby Blake Mathy
Der Menschgewordene als Ebenbild Gottes. Zum frühchristlichen Verständnis der Imago Dei
No full textThe author interprets the image of God in relation to the disparity between various Old and New Testament statements and examines it in the light of contemporary questions posed by the theory of evolution. He shows that the disparate biblical statements do not permit us to develop an anthropology based on the concept of the image of God. Nevertheless the author shows that this concept – even against the New Testament background of the christological exclusivity of the Imago Dei – is relevant for the understanding of humans as mediators

(2018) uncover surprising and distinct effects of deleting the epigenetic regulators HDAC1 and HDAC2 during microglial development versus during the course of neurodegeneration

The idea of a critical social theory: past, present and future
No full textThrough a rereading of the development of critical theory of the Frankfurt School, the article attempts to show in which way Axel Honneth’s theory is part of a process of learning and change of paradigm in the tradition of the Critical Theory of the Frankfurt School, inaugurated by Max Horkheimer in its inaugural class (Antrittsvorlesung) at the Instut for Social Research. Furthermore, the author presents the main questions that this theoretical model has to respond if it wants to present an answer to the contemporary problems. The autor also suggests that this theory needs to clarify the reasoning of his mormativity and to improve interdisciplinarity.Através de uma releitura do desenvolvimento da teoria crítica da Escola de Frankfurt, o artigo procura mostrar em que sentido a teoria de Axel Honneth se insere no processo de aprendizagem e de mudanças de paradigma da tradição teórica da teoria crítica da Escola de Frankfurt, inaugurada por Max Horkheimer em sua Aula inaugural (Antrittsvorlesung) no Instuto de Pesquisa Social. Além disso, o autor apresenta as dificuldades principais que esse modelo teórico tem e terá de enfrentar para continuar à altura dos problemas contemporâneos e sugestões para o seu desenvolvimento, como a fundamentação da normatividade e a interdisciplinaridade
