The Paradigm of the Void: Louise Glück’s Post-Confessional Deadlock

Awarded the Nobel Prize in literature, Louise Glück emerges as one of the major and most important American poets of the late 20th and early 21st century. What does this centrality tell us about the trajectory that the American poetry has traced since modernism? I attempt to offer a critical evaluation of Glück’s post-confessional stylistic, developed between the debut Firstborn (1968) and Averno (2006), by setting it in contexts that are historical and, later in the paper, psycho-theological. First, I treat her formula as a double response – to the modernist legacy of T. S. Eliot and to the challenges of postmodernity. Faithful to Eliot’s urge to transcend the biographical by connecting it with the transcendental, Glück resists the skeptical thesis of the demise of grand narratives, and writes in defiance of the postmodernist poetics of such poets as John Ashbery. Not undermining the biographical foundation of the lyric – the way Ashbery has done in his linguistic excess – she strives to make it paradigmatic. However, in this heroic search for a paradigm, Glück proposes a deeply ambiguous modification of Eliot that I characterize in psycho-theological terms. Following Agata Bielik-Robson’s research, I characterize Glück’s metaphysics as a form of Thanatic Lacanian Gnosticism. At this level we confront the costs of Glück’s post-confessionalism: a serious impairment of all those aspects of the self that make it an embodied and gendered human being.

Evolution of Scintillation and Electrical Characteristics of AlGaN Double-Response Sensors During Proton Irradiation

Wide bandgap AlGaN is one of the most promising materials for the fabrication of radiation hard, double-response particle detectors for future collider facilities. However, the formation of defects during growth and fabrication of AlGaN-based devices is unavoidable. Furthermore, radiation defects are formed in detector structures during operation at extreme conditions. In this work, study of evolution of the proton-induced luminescence spectra and short-circuit current has been simultaneously performed during 1.6 MeV proton irradiation. GaN and AlGaN (with various Al concentrations) epi-layers grown by metalorganic chemical vapour deposition technique and Schottky diode structures have been examined. Variations of spectral and electrical parameters could be applied for the remote dosimetry of large hadron fluences.

Surface work-hardening optimization of cold roll-beating splines based on an improved double-response surface-satisfaction function method

The work hardening of a spline during cold roll-beating is used as an indicator to evaluate the mechanical properties of the surface. To further optimize the work-hardening degree of a cold roll-beating spline surface, weight theory and satisfaction functions are used to improve the double-response surface-satisfaction function model. The model describes the involute spline based on the cold roll-beating speed and feed rate. The generalized reduced-order gradient method is applied to optimize the optimal combination of processing parameters. The experiments validate the optimization results of the improved double-response surface-satisfaction function method and the conventional response surface method based on the cold roll-beating spline test and a comparative analysis of the spline surface metallographic structure. The results show that the satisfaction degree of the improved response model is 0.87384, indicating that the model is robust and reliable. The optimized processing parameters are a cold roll speed of 1448.21 r/mm, a feed rate of 41.71 mm/min, and a degree of work hardening of 144.79%. The spline surface work-hardening degree based on the revised model is higher than that of the conventional model. Thus, the improved double-response surface-satisfaction function model provides better accuracy.
