This article addresses the broader question of the special issue by reflecting on the coloniality of knowledge production in a context of global climate governance. Drawing on the rationale of the special issue, we highlight key dynamics in which knowledge shape climate policies and propose a decolonial approach at the nexus of academic knowledge production and policy formation by accounting for diverse ways of knowing climate justice. To this end, the article asks how to develop a decolonial approach to researching climate justice in order to identify the meaning-in-use of climate justice by affected people in what we describe as sensitive regions of the Arctic and the Mediterranean. To this end, the article develops a research design that accounts for diverse ways of knowing. The article proceeds as follows: first, we will discuss how diverse ways of knowing are related to global climate governance and climate justice; second, we outline our practice-based research framework that addresses research ethics, decolonial approaches and norm contestation; and third, we discuss how our approach can inform not only the co-production of research in climate governance, but also current debates on climate justice.

Background: Resection followed by local radiation therapy (RT) is the standard of care for symptomatic brain metastases. However, the optimal technique, fractionation scheme and dose are still being debated. Lately, low-energy X-ray intraoperative RT (lex-IORT) has been of increasing interest. Method: Eighteen consecutive patients undergoing BM resection followed by immediate lex-IORT with 16–30 Gy applied to the spherical applicator were retrospectively analyzed. Demographic, RT-specific, radiographic and clinical data were reviewed to evaluate the effectiveness and safety of IORT for BM. Descriptive statistics and Kaplan–Meyer analysis were applied. Results: The mean follow-up time was 10.8 months (range, 0–39 months). The estimated local control (LC), distant brain control (DBC) and overall survival (OS) at 12 months post IORT were 92.9% (95%-CI 79.3–100%), 71.4% (95%-CI 50.2–92.6%) and 58.0% (95%-CI 34.1–81.9%), respectively. Two patients developed radiation necrosis (11.1%) and wound infection (CTCAE grade III); both had additional adjuvant treatment after IORT. For five patients (27.8%), the time to the start or continuation of systemic treatment was ≤15 days and hence shorter than wound healing and adjuvant RT would have required. Conclusion: In accordance with previous series, this study demonstrates the effectiveness and safety of IORT in the management of brain metastases despite the small cohort and the retrospective characteristic of this analysis.

Die Forderung nach »kritischer« Normenforschung in den IB durch Engelkamp et al. und Deitelhoff/Zimmermann aufgreifend, pladieren wir dafur, mithilfe eines kritisch-konstruktivistischen Forschungsprogramms uber eine poststrukturalistische Perspektive hinauszugehen, die lediglich hegemoniale Strukturen hinterfragt. Normenforschung muss »kritisch« bleiben – hier stimmen wir mit den vorangegangenen Beitragen in der ZIB uberein. Gelingen kann dies jedoch nur, wenn beforschte Akteurinnen und Akteure vor einer normativen Bewertung der Forschenden zunachst fur sich selbst sprechen konnen und ihren Artikulationen weder theoretisch noch methodologisch vorgegriffen wird. In Anlehnung an kritisch-konstruktivistische Forschung schlagen wir daher eine induktive Forschungsstrategie vor, die genau dies ermoglicht und dabei die doppelte Hermeneutik forschungspraktisch umsetzt. Gelingt dies, wird lokalen Akteurinnen und Akteuren agency zugestanden und sie sprechen fur sich selbst. Dann erst ist (Normen-)Forschung kritisch. Empirisch illustriert der Artikel eine solche Forschungsstrategie anhand einer rekonstruktiven Analyse des meaning-in-use der Normen »Freiheit« und »Gleichberechtigung« anhand der Reaktionen auf die Protestaktionen von FEMEN in der WANA-Region.
