Recognition and Disrespect. Lordship and Bondage in Hegel's Phenomenology of Spirit

With regard to the contemporary discussion of recognition and disrespect in social philosophy, this chapter argues that Hegel is not only a seminal 'theorist of recognition,' but also a sophisticated 'theorist of disrespect.' By means of the relationship of lord and bondsman as developed in the Phenomenology of Spirit it is shown that for Hegel the emergence of recognition not only involves freedom and autonomy but can also result in dependency and asymmetry. Building on this assumption, the paper pursues a threefold aim: first, to show, through a reconstruction of Hegel's thoughts on the development of self-consciousness, that a successful form of subjectivation is only possible when a subject can actualize itself in so called 'egalitarian' and 'differential' acts of recognition. The second part aims at a re-reading of Hegel's thinking of the lord/bondsman-relationship. In opposition to the classic 'heroic reading' of this relationship, I make the case for a 'subaltern reading,' arguing that Hegel presents in the figure of the bondsman a form of asymmetric recognition, in which the subject is bound to those conditions that hold it in disrespect. Finally, the third part aims at a reinterpretation of Hegel's thought from the perspective of disresprect in order to show that the other side of Hegel's theory of recognition forms a theory of symbolic vulnerability. Starting from this theory one can understand the paradoxical dynamic of disrespect that leads subjects to identify with the relations that subjugate them

Asymmetrical Reciprocity. From Recognition to Responsibility and Back

In this article, I argue that Hegel’s concept of recognition and Levinas’ concept of responsibility complement each other and lead to the idea of an asymmetrical reciprocity in which the origin of our social relations is not mutual equality, but rather mutual inequality. I will unfold this argument in three steps. I will first work out a fundamental asymmetry of recognition in Hegel by means of the figure of the bondsman before elucidating in a second step the asymmetry of responsibility in Levinas by means of the figure of the hostage. In the last and third step, I will correlate both asymmetries and show how far the asymmetry of recognition and the asymmetry of responsibility constantly develop from and transition into one another in our social relationships

Statistical Laws and Mechanics of Voronoi Random Lattices

We investigate random lattices where the connectivities are determined by the Voronoi construction, while the location of the points are the dynamic degrees of freedom. The Voronoi random lattices with an associated energy are immersed in a heat bath and investigated using a Monte Carlo simulation algorithm. In thermodynamic equilibrium we measure coordination number distributions and test the Aboav-Weaire and Lewis laws.Comment: 14 pages (figures not included), LaTeX, HLRZ-26/9

Bursts in discontinuous Aeolian saltation

Close to the onset of Aeolian particle transport through saltation we find in wind tunnel experiments a regime of discontinuous flux characterized by bursts of activity. Scaling laws are observed in the time delay between each burst and in the measurements of the wind fluctuations at the fluid threshold Shields number $\theta_c$. The time delay between each burst decreases on average with the increase of the Shields number until sand flux becomes continuous. A numerical model for saltation including the wind-entrainment from the turbulent fluctuations can reproduce these observations and gives insight about their origin. We present here also for the first time measurements showing that with feeding it becomes possible to sustain discontinuous flux even below the fluid threshold

A low-temperature dynamic mode scanning force microscope operating in high magnetic fields

A scanning force microscope was implemented operating at temperatures below 4.2K and in magnetic fields up to 8T. Piezoelectric quartz tuning forks were employed for non optical tip-sample distance control in the dynamic operation mode. Fast response was achieved by using a phase-locked loop for driving the mechanical oscillator. Possible applications of this setup for various scanning probe techniques are discussed.Comment: 5 pages, 5 figures, submitted to "Review of Scientific Instruments

SUSY-QCD corrections to stop annihilation into electroweak final states including Coulomb enhancement effects

We present the full $\mathcal{O}(\alpha_s)$ supersymmetric QCD corrections for stop-anti-stop annihilation into electroweak final states within the Minimal Supersymmetric Standard Model (MSSM). We also incorporate Coulomb corrections due to gluon exchange between the incoming stops. Numerical results for the annihilation cross sections and the predicted neutralino relic density are presented. We show that the impact of the radiative corrections on the cosmologically preferred region of the parameter space can become larger than the current experimental uncertainty, shifting the relic bands within the considered regions of the parameter space by up to a few tens of GeV.Comment: 20 pages, 13 figures, updated to version published in Phys.
