German Professors’ Motivation to Act as Peer Reviewers in Accreditation and Evaluation Procedures
(2021-01-09)
Acting as a reviewer is considered a substantial part of the role-bundle of the academic profession (quality assurance (QA) and quality enhancement (QE) role). Research literature about peer review, for example, for journals and grants, shows that acting as a peer reviewer adds to an academic’s reputation. However, little is known about academics’ motivation to act as reviewers. Based on self-determination theory, the multidimensional work motivation scale (Gagné et al. 2015) is used for a survey of German professors ...

A Novel Approach to Robustly Determine Residual Stress in Additively Manufactured Microstructures Using Synchrotron Radiation
(2021-07-29)
In recent decades additive manufacturing (AM) for years has been in focus of academia and industry as its underlying production principle allows for the realization of designs of unprecedented geometrical complexity. However, often such structures are not realized due to the lack of understanding of structural and mechanical properties, this fact amongst others related to the unique microstructures established by the related processes. In this context, residual stresses, highly affected by the scan strategy and process ...

Comeback als demokratische Führungsmacht?
(2021-07-08)
Joe Biden stellt die US-Außenpolitik unter ein demokratisches Paradigma, will demokratische Allianzen festigen und hat einen „Gipfel für die Demokratie“ versprochen. Ziel ist es, das Gewicht freiheitlicher Staaten im Systemkonflikt mit Autokratien zu erhöhen. Bündnispartner in Europa und Asien reagieren skeptisch, fürchten eine Verhärtung der Konflikte mit China und Russland und den Verlust der Handlungsfreiheit. Wir plädieren für eine Allianz der Demokratien, mit Blick auf die Resilienz ihrer politischen Systeme und ...

A Critical Review and Assessment of Different Thermoviscoplastic Material Models for Simultaneous Hot/Cold Forging Analysis
(2020-05-26)
The simultaneous hot/cold forging is an innovative production process, taking advantage of the high accuracy for cold forming and low forces for hot forming. However, the choice of a suitable material model for such a large temperature range is a difficult issue and insufficiently regarded. Hence, the aim of this contribution is a critical review and assessment of the prediction capability and accuracy of three already existing thermo-viscoplasticity models. Therefore, the simulation results of the Bammann, Chiesa ...

Karin Bock, Nina Göddertz, Franziska Heyden, Miriam Mauritz (Hrsg.) (2019). Zugänge zur Kinderladenbewegung
(2020-06-16)
Der Sammelband entstand als neueste Publikation aus dem Projekt „Die Kinderladenbewegung: Biographische Auswirkungen und gesellschaftspolitische Einflüsse institutioneller Erziehungsarrangements“ und rahmt diesen Forschungszusammenhang auf unkonventionelle Art. Ihn kennzeichnet vor allem ein sehr breites Spektrum an Artikeln, die 1968 und die Kinderladenbewegung aus unterschiedlichsten Perspektiven beleuchten, womit er auch dem Anspruch der Herausgeber_innen, die „(…) Vielschichtigkeit und Verschiedenheit der Zugänge ...

Fecal Cortisol Metabolites in Dairy Cows: A Cross-Sectional Exploration of Associations with Animal, Stockperson, and Farm Characteristics
(2020-10-01)
To date, little is known about influences on cows’ physiological stress levels on farms. The present study explored associations of fecal cortisol metabolite concentrations (FCM) with (1) farm factors including human–animal contact, (2) cows’ fear behaviors towards humans, and (3) milk production and udder health, involving 25 dairy farms and repeated fecal samples (n = 2625) from 674 focal cows. Farm factors via interviews and observations, avoidance distance (AD) and qualitative behavior assessment (QBA) during a ...

Oxidation Reactions of the N-Heterocyclic Stannylenes [𝘰-C₆H₄ (NSi𝑡BuMe₂)]₂Sn and [{Fe(η⁵ -C₅H₄ -NSi𝑡BuMe₂)₂}Sn] with Sulfur, Selenium, and Diphenyl Diselenide
(2020-01-27)
The N‐heterocyclic stannylenes [{Fe(η$^5$‐C$_5$H$_4$‐NSi𝑡 BuMe$_2$)$_2$}Sn] (1 ) and [𝘰‐C$_6$H$_4$(NSi𝑡 BuMe$_2$)]$_2$Sn (2 ) were prepared in one‐pot reactions from SnCl$_2$, LiN(SiMe$_3$)$_2$, and the corresponding diamine, viz. [Fe(η$^5$‐C$_5$H$_4$‐NHSi𝑡 BuMe$_2$)$_2$] and 𝘰‐C$_6$H$_4$(NSiH𝘵 BuMe$_2$)$_2$, respectively. Oxidative addition reactions of 1 and 2 with S$_8$ and Se$_8$, respectively, afforded the corresponding 1,3,2,4‐dithiadistannetanes ((1 S$_2$), (2 S$_2$)), and 1,3,2,4‐diselenadistannetanes ...

Influence of pre-drying storage time on essential oil components in dried hops (Humulus lupulus L.)
(2020-10-15)
BACKGROUND
It is well known that duration of pre-drying storage impacts on hop quality. However, little knowledge exists regarding its actual effects on valuable hop components. To investigate these effects, fresh hop cones were stored for 5 or 24 h and dried for 210 min at 65 °C thereafter. Furthermore, to understand the effect of freezing hop cones on the essential oil content, both fresh and stored samples were frozen before and after drying.
RESULTS
The results from gas chromatography analysis show an increase ...

On the Influence of Microstructure on the Corrosion Behavior of Fe–Mn–Al–Ni Shape Memory Alloy in 5.0 wt% NaCl Solution
(2020-10-03)
Herein the corrosion behavior of Fe–Mn–Al–Ni shape memory alloys characterized by different microstructures in a 5.0 wt% NaCl solution is investigated. Open circuit potential and potentiodynamic polarisation tests are conducted. Generally, Fe–Mn–Al–Ni shows corrosion properties being similar to pure iron. However, the polarization curves of single crystals indicate the presence of an unstable passive system. The corrosion damage is analyzed by means of optical microscopy and electron microscopy. It is revealed that ...

Inclusive Resettlement? Integration Pathways of Resettled Refugees With Disabilities in Germany and Canada
(2021-12-09)
The purpose of this article is to explore the existing intersectional knowledge on integration and resettlement of refugees with disabilities in two of the top five resettlement countries in the world, Germany and Canada. There is limited research on the intersection of migration and disability, especially in the context of refugee resettlement. Reflecting the dominant pathways of migration in each country, what little research there is focuses on asylum seekers in Germany, and immigrants in Canada. The review describes ...
