The artistic practice of exorcism: Shabnam Shabazi (in conversation with Simon Ellis)
No full textThis is a conversation between artist Shabnam Shabazi and choreographer (and Choreographic Practices co-editor) Simon Ellis. They discuss Shabazi’s practice and focus on her interest in the archive as a creative resource, the role of the concept of home in her creative work and in the ways in which our bodies are sites of transformation for artists and participants
#DefendingTheDefenders – Episode 3: Afghanistan
No full textWhen the Taliban took over power in Afghanistan in the summer of 2021, it was a disaster for women. Immediately, they were stripped of their rights, in particular their political rights. In the third episode of #DefendingTheDefenders, a podcast by Deutscher Anwaltverein and Verfassungsblog, we talk to Shabnam Salehi about the human rights situation in Afghanistan and the rights of women in particular. Shabnam describes the years leading up to the Taliban coup as a golden era of women’s rights. At the initiative of human rights activists, the government had taken many steps to promote and protect women and their rights. Even more importantly, women have been educated about their rights. While there were many challenges for human rights activists during these years, Shabnam says, a lot of progress has been made. After the Taliban gripped power, they immediately began to push back on women’s rights, but Shabnam explains what the perspectives of human rights activism in and for Afghanistan are and why she remains hopeful. In the second segment of this episode, we talk to Matthias Lehnert about the shortcomings of the German and European migration law system. The Afghanistan example shows a slow system designed to prioritise perceived security issues over human rights in some cases, Matthias says. Current regulatory proposals also reveal that the work of attorneys is perceived as a threat to this priority rather than an execution of the right to access to justice

The impact of ZnO nanotube on the performance of hybrid inorganic/organic light-emitting diode as a single-mode ring-core UV waveguide
No full textAfter a systematic survey in hybrid inorganic/organic light-emitting heterostructure devices based on ZnO in the last decay, in this novel work, the impact of the single-mode ring-core waveguide based on ZnO nanotube (NT)/MEH-PPV for ultraviolet organic light-emitting diode (UV-OLED) application has been carefully scrutinized for the first time. The proposed structure has been fabricated, simulated and compared with conventional ZnO nanorod (NR)/MEH-PPV structure. To synthesize ZnO NTs, the as-grown chemical bath deposited ZnO NRs have been etched in KCL solution in various molar (M) concentration, etching time and etching temperature. The optimized etching condition is obtained in 1 M concentration of KCL solution, 4 h etching time and 90 °C temperature. The structural properties (such as strain, stress and texture coefficient), electrical properties (such as band gap energy) and optical properties (such as Urbach energy, absorbance and photoluminescence spectra) of ZnO NTs have been investigated, systematically. In continue, hybrid UV-OLEDs have been fabricated based on ZnO NRs and ZnO NTs. According to the results, ZnO NT-based OLED depicts superior electrical and optical results including lower turn-on voltage (11.2 V < 15 V) and higher UV peak in electroluminescence spectra with respect to ZnO NR-based device. To acquire more enlightenment about UV emission mechanism, the proposed devices have been simulated through Silvaco TCAD and Lumerical FDTD software. The results from simulations illustrate great agreement with experimental results. Higher radiative recombination rate, higher Purcell factor and single-mode waveguiding effect of ring-core ZnO NT lead to major superiority of the ZnO NT-based UV-OLED fabricated and simulated in this work
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
