Reihe „Bürger*innenbeteiligung im Teilprojekt Vulnerabilität und Sicherheit in der gerechten Stadt (VERSS)“

Das vorliegende Working Paper ist das erste einer zweiteiligen Working‐Paper‐Reihe zum Thema „Bürger*innenbeteiligung“, die im Rahmen des vom BMBF geförderten Teilprojekts„Vulnerabilität und Sicherheit in der gerechten Stadt“ entstanden sind. Es bespricht die verschiedenen Verfahrensweisen in und Umgänge mit der Beteiligung von Bürger*innen. Zu diesem Zweck bereitet es den so genannten State of the Art auf und bespricht dabei den Aspekt der sozialen Nachhaltigkeit von Bürger*innenbeteiligung. Eine sozialnachhaltige Gestaltung und Planung von Beteiligungsverfahren zielt auf „passgenaue“ und sozialverträgliche Maßnahmen und Entwicklungen, die auf Kooperation, Anerkennung und Transparenz fußen. Welche Schritte gilt es dabei zu bedenken und wie werden Beteiligungsverfahren in der Forschung besprochen? Das vorliegende Working Paper stellt zunächst die Debatte zur Partizipation mit einem Anwendungsschwerpunkt auf Kommunen vor. Im Anschluss diskutieren wir eine Methodologie, die die theoretischen Argumente aufgreift und in die Anwendung durch den VERSS‐Werkzeugkasten mündet

Current-Driven Domain-Wall Dynamics in Curved Ferromagnetic Nanowires

The current-induced motion of a domain wall in a semicircle nanowire with applied Zeeman field is investigated. Starting from a micromagnetic model we derive an analytical solution which characterizes the domain-wall motion as a harmonic oscillation. This solution relates the micromagnetic material parameters with the dynamical characteristics of a harmonic oscillator, i.e., domain-wall mass, resonance frequency, damping constant, and force acting on the wall. For wires with strong curvature the dipole moment of the wall as well as its geometry influence the eigenmodes of the oscillator. Based on these results we suggest experiments for the determination of material parameters which otherwise are difficult to access. Numerical calculations confirm our analytical solution and show its limitations

Roots and routes in neighbourhoods. Length of residence, belonging and public familiarity in Berlin, Germany

Urban scholars commonly expect that residents show more neighbourhood belonging, the longer they live in an area. An imagery of fixed settlements thus remains dominant in a rapidly changing world. Recent research challenged classic assumptions but the alternative of elective belonging hardly differentiated between symbolic and practical neighbourhood use. As belonging is performatively maintained, this differentiation may be needed. What defines residents’ belonging in a neighbourhood in digital mobile times? Does length of residence alone result in place-based practices, familiarity with other people and ultimately in more belonging? Our analyses of survey-data from four Berlin neighbourhoods show that length of residence correlates with belonging, but not in a simple linear way. The use of infrastructure and especially public familiarity, which depends on the settlement as specific historical configuration, affect this relationship.城市学者普遍认为，居民在一个地区居住的时间越长，就越有邻里归属感。因此，固定定居点的意象在瞬息万变的世界中仍然占主导地位。最近的研究对经典假设提出了质疑，但选择性归属的替代方案 几乎没有区分象征性和实际的邻里功能。由于归属感是通过行动来维持的，因此可能需要对它们进行区分。在数字化、移动化时代，如何定义居民对社区的归属感？仅仅长时间的居住就会带来基于地方的实践、与他人的熟悉并最终带来更多的归属感？我们对柏林四个街区的调查数据进行了分析，发现居住时间长短与归属感相关，但并非以简单的线性方式相关。基础设施的使用，尤其是公众熟悉度，会影响这种关系。而公众熟悉度取决于作为特定历史配置的定居点。Peer Reviewe

Pazopanib, Cabozantinib, and Vandetanib in the Treatment of Progressive Medullary Thyroid Cancer with a Special Focus on the Adverse Effects on Hypertension

Medullary thyroid cancer (MTC) is a rare malignancy with a poor prognosis. First line therapy is surgery, which is the only curative method of the disease. However, in non-operable cases or with tumor progression and metastases, a systemic treatment is necessary. This form of cancer is often insensitive to conventional chemotherapy, but the use of tyrosine kinase inhibitors (TKIs), such as pazopanib, cabozantinib, and vandetanib, has shown promising results with an increase in progression-free survival and prolonged lifetime. Therefore, we focused on the pharmacological characteristics of TKIs, their mechanism of action, their application as a secondary treatment option for MTC, their efficacy as a cancer drug treatment, and reviewed the ongoing clinical trials. TKIs also act systemically causing various adverse events (AEs). One common AE of this treatment is hypertension, known to be associated with cardiovascular disease and can therefore potentially worsen the well-being of the treated patients. The available treatment strategies of drug-induced hypertension were discussed. The mechanism behind the development of hypertension is still unclear. Therefore, the treatment of this AE remains symptomatic. Thus, future studies are necessary to investigate the link between tumor growth inhibition and hypertension. In addition, optimized, individual treatment strategies should be implemented

Kooperativ gefördert? Ausgewählte Ergebnisse einer Evaluation des Promotionskollegs der Hans-Böckler-Stiftung

Es fehlt eine aktuelle Studie, die die strukturellen Rahmenbedingungen, Prozessqualität sowie die Effekte und Ergebnisse der von der Hans-Böckler-Stiftung geförderten Promotionskollegs nach einer inzwischen über zehnjährigen Laufzeit in den Blick nimmt. An diesem Forschungsdefizit setzt die … durchgeführte quantitativ und qualitativ angelegte Evaluationsstudie an. Die Autoren stellen im vorliegenden Beitrag einige solcher ausgewählten Ergebnisse vor, von denen sie annehmen, dass sie über den Kontext der Böckler-Kollegs hinaus für die Entwicklung von Graduiertenkollegs im Allgemeinen relevant sein dürften.

Neutron stars in Gauss-Bonnet gravity -- nonlinear scalarization and gravitational phase transitions

It was recently discovered that scalarized neutron stars in scalar-tensor theories can undergo a gravitational phase transition to a non-scalarized (GR) state. Surprisingly, even though the driving mechanism is totally different, the process resembles closely the first-order matter phase transition from confined nuclear matter to deconfined quark matter in neutron star cores. The studies until now were limited, though, to only one theory of gravity and a limited range of parameters. With the present paper, we aim at demonstrating that gravitational phase transitions are more common than expected. More specifically, we show that the phenomenon of nonlinear scalarization is present for neutron stars in Gauss-Bonnet gravity leading to the possibility of gravitational phase transition. Moreover, it can be observed for a wide range of parameters so no fine-tuning is needed. This solidifies the conjecture that gravitational phase transitions are an important phenomenon for compact objects and their astrophysical implications deserve an in-depth study.Comment: 16 pages, 5 figure

Spin crossover in a vacuum-deposited submonolayer of a molecular iron(II) complex

Spin-state switching of transition-metal complexes (spin crossover) is sensitive to a variety of tiny perturbations. It is often found to be suppressed for molecules directly adsorbed on solid surfaces. We present X-ray absorption spectroscopy measurements of a submonolayer of [FeII(NCS)2L] (L: 1-{6-[1,1-di(pyridin-2-yl)ethyl]-pyridin-2-yl}-N,N-dimethylmethanamine) deposited on a highly oriented pyrolytic graphite substrate in ultrahigh vacuum. These molecules undergo a thermally induced, fully reversible, gradual spin crossover with a transition temperature of T1/2 = 235(6) K and a transition width of ΔT80 = 115(8) K. Our results show that by using a carbon- based substrate the pin-crossover behavior can be preserved even for molecules that are in direct contact with a solid surface
