The Role of Bargaining Power
(2019)
Neoclassical theory omits the role of bargaining power in the determination of wages. As a result, the importance of changes in the bargaining position for the development of income shares in the last decades is underestimated. This paper presents a theoretical argument why collective bargaining power is a main determinant of workers’ share of income and how its decline contributed to the severe changes in the distribution of income since the 1980s. In order to confirm this hypothesis, a panel data regression analysis is performed that suggests that unions significantly influence the distribution of income in developed countries.
Pedagogy of integrity
(2019)
The master thesis “Pedagogy of Integrity: an Analysis of the Conceptualization and Implementation of the MA Program Anglophone Modernities in Literature and Culture” deals with colonial patterns in higher education practices. It provides a theoretical framework for decolonization of academic teaching-learning practices on the micro- and meso-didactic levels and suggests concrete solutions for the decolonized education practices, especially for degree programs, which content focuses on post-colonial issues. Besides, through the exemplary analysis of the conceptualization and implementation of the MA Program Anglophone Modernities in Literature and Culture the work explores patterns of colonial heritage as well as will to decolonise these. The main thesis claims that (higher) education should be liberated from colonial patterns, so that real participation for all students in the collective knowledge production becomes possible.
In the theoretical elaborations different concepts of critical and radical pedagogy, e.g. the ones of Paulo Freire and bell hooks, in combination with concepts about modalities of adult learning (e.g. transformative learning) and approaches to education, seeking to combine learning and social justice (e.g. Social Justice Learning) are systematised and explored for their substance and potential to contribute to a criteria catalogue for decolonised educational practises. Besides, attention is paid on higher education research results, which reveal, that students, who belong to underrepresented groups at university (non-traditional students) in their societies of origin, face more difficulties and discrimination as international students at Western universities, than ‘traditional’ international students do. Based on the theoretical elaborations, the work claims that:
(1) the homogeneity-preserving dynamics, found in Western colleges, are an inheritance of colonial time and mindsets, which continue to function in education and multiply social inequality in the context of internationalization, migration, and participation;
(2) all, but especially those higher educational programs, dealing explicitly with inequality phenomena, social and cultural diversity, power relations and issues of domination, as well as with postcolonial criticism, should establish premises of equity and provide de-facto equal opportunities for participation through embodiment of social justice as a way to remain credible;
(3) decolonization of the educational space can be enabled through appropriate didactic action both on the meso- (institution) and micro-didactical (teaching-learning arrangements) agency levels with sufficient will and willingness of responsible professionals at.
By examining representative documents, published by the MA Program Anglophone Modernities in Literature and Culture, using the 'close reading' methodology, as well as through the exemplary analysis of the concept of a teaching-learning program’s event and a student survey, the work seeks to examine wo what extent the Master's Degree Program represents a space of decolonised higher education. The results of the analysis indicate the need for stronger normative value-positioning of the Study program, while many practices that show commitment to participation, social justice and diversity, have been identified.
In the last chapter, the results of the theoretical elaboration and the program’s analysis are synthesized in the concept of an integrity-based pedagogy conceptualisation, called Pedagogy of Integrity, and suggestions are formulated for the teaching practice in the study program, which are meant to help overcome the discrepancy between will and practice towards decolonised educational space.
Dynamic earthquake rupture modeling provides information on the rupture physics as the rupture velocity, frictions or tractions acting during the rupture process. Nevertheless, as often based on spatial gridded preset geometries, dynamic modeling is depending on many free parameters leading to both a high non-uniqueness of the results and large computation times. That decreases the possibilities of full Bayesian error analysis.
To assess the named problems we developed the quasi-dynamic rupture model which is presented in this work. It combines the kinematic Eikonal rupture model with a boundary element method for quasi-static slip calculation.
The orientation of the modeled rupture plane is defined by a previously performed moment tensor inversion. The simultanously inverted scalar seismic moment allows an estimation of the extension of the rupture. The modeled rupture plane is discretized by a set of rectangular boundary elements. For each boundary element an applied traction vector is defined as the boundary value.
For insights in the dynamic rupture behaviour the rupture front propagation is calculated for incremental time steps based on the 2D Eikonal equation. The needed location-dependent rupture velocity field is assumed to scale linearly with a layered shear wave velocity field.
At each time all boundary elements enclosed within the rupture front are used to calculate the quasi-static slip distribution. Neither friction nor stress propagation are considered. Therefore the algorithm is assumed to be “quasi-static”. A series of the resulting quasi-static slip snapshots can be used as a quasi-dynamic model of the rupture process.
As many a priori information is used from the earth model (shear wave velocity and elastic parameters) and the moment tensor inversion (rupture extension and orientation) our model is depending on few free parameters as the traction field, the linear factor between rupture and shear wave velocity and the nucleation point and time. Hence stable and fast modeling results are obtained as proven from the comparison to different infinite and finite static crack solutions.
First dynamic applications show promissing results. The location-dependent rise time is automatically derived by the model. Different simple kinematic models as the slip-pulse or the penny-shaped crack model can be reproduced as well as their corresponding slip rate functions. A source time function (STF) approximation calculated from the cumulative sum of moment rates of each boundary element gives results similar to theoretical and empirical known STFs.
The model was also applied to the 2015 Illapel earthquake. Using a simple rectangular rupture geometry and a 2-layered traction regime yields good estimates of both the rupture front propagation and the slip patterns which are comparable to literature results. The STF approximation shows a good fit with previously published STFs.
The quasi-dynamic rupture model is hence able to fastly calculate reproducable slip results. That allows to test full Bayesian error analysis in the future. Further work on a full seismic source inversion or even a traction field inversion can also extend the scope of our model.
In this cartography, I examine M.K. Gandhi’s practice of fasting for political purposes from a specifically aesthetic perspective. In other words, to foreground their dramatic qualities, how they in their expressive repetition, patterning and stylization produced a/effected heightened forms of emotions. To carry out this task, I follow the theater scholar Erika Fischer-Lichte’s features that give name to her book Äesthetik des Performativen (2004). The cartography is framed in a philosophical presentation of Gandhi’s discourse as well as of his historical sources. Moreover, as a second frame, I historicize the fasts, by means of a typology and teleology in context.
The historically and discoursively framed cartography maps four main dimensions that define the aesthetics of the performative: mediality, materiality, semioticity and aestheticity. The first part analyses the medial platforms in which the fasts as events have been historically recorded and in which they have left their traces and inscriptions. These historical sources are namely, newspapers, images, newsreels and a documentary film. Secondly, the material dimension depicts Gandhi’s corporeal condition, as well as the spatiality and temporality of the fasts. In the third place, I revise and reformulate critically Fischer-Lichte’s concepts of “presence” and “representation” with resonating concepts of G. C. Spivak and J. Rancière. This revision illustrates Gandhi’s fasts and shows the process of how an individual may become the embodiment or representation of a national body-politic. The last chapter of the cartography explores the autopoetic-feedback loop between Gandhi and the people and finishes with a comparison of the mise en scène of the hunger artists with the fasts of the Indian the politician, social reformer, and theologian. The text concludes interpreting Gandhi’s practice of fasting under the light of the concepts of “intellectual emancipation” and “de-subjectivation” of the philosopher J. Rancière.
The four main concerns of this cartography are: Firstly, in the field of Gandhi’s reception, to explore the aesthetic dimension as both alternative and complementary to the two hegemonic interpretative lenses, i.e. a hagiographic or a secular political understanding of the fasts. From a theoretical perspective, the cartography pursues to be a transdisciplinary experiment that aims at deploying concepts that have been traditionally developed, derived from and used in the field of the arts (theater, film, literature, aesthetic performance, etc.) in the field of the political. In brief, inverting an expression of Rancière, to understand politics as aesthetics. Thirdly, from a thematic point of view, the cartography inquires the historical forms of staging and perception of hunger. Last yet importantly, it is an inquiry of the practice of fasting as nonviolence, what Gandhi, its most sophisticated modern theoretician and practitioner considered its most radical expression.
