“…The Fine Guidance Sensor (FGS) instrument (Doyon et al 2012) provides the tracking information using known point sources that are mainly from the Guide Star Catalog (Lasker et al 2008). This catalog has an accuracy of ∼0:4″ (Morrison et al 2001).…”

We describe the operations concept and data reduction plan for the Mid-Infrared Instrument (MIRI) for the James Webb Space Telescope (JWST). The overall JWST operations concept is to use Observation Templates (OTs) to provide a straightforward and intuitive way for users to specify observations. MIRI has four OTs that correspond to the four observing modes: 1.) Imaging, 2.) Coronagraphy, 3.) Low Resolution Spectroscopy, and 4.) Medium Resolution Spectroscopy. We outline the user choices and expansion of these choices into detailed instrument operations. The data reduction plans for MIRI are split into three stages, where the specificity of the reduction steps to the observation type increases with stage. The reduction starts with integration ramps: stage 1 yields uncalibrated slope images; stage 2 calibrates the slope images; and then stage 3 combines multiple calibrated slope images into high level data products (e.g. mosaics, spectral cubes, and extracted source information). Finally, we give examples of the data and data products that will be derived from each of the four different OTs.

“…In this context, the European b/order implemented during the 2000s must be considered as a recent evolution in the history of this border regime-a new layer that interacts with local configurations and social orders and contributes to the evolution of both cross-border practices and the border itself. Transposing the critics of the so-called transition to borders studies here, the issue is thus to consider the fluidity between historical periods, the ways in which they may overlap within the same social interactions (Doyon/Brotherton 2008;Gilbert et al 2008), and how they might be mobilized by actors across the national boundaries. Borders being historically contingent constructions (Del Sarto 2010, 151) connected to a large scope of contexts-be it institutional, historical, cultural, and/or linguistic-contextualization into time and space is therefore necessary to grasp their complexity and to understand local practices.…”

This interdisciplinary anthology addresses the criticism that previous investigations of borders often lack complexity and, therefore, fall short. Instead, the authors assess the complex interplay of elements and dimensions of borders and show how this gives rise to instances of disorder/order and how such disorder/order becomes socially and spatially effective. They discuss principles of complexity-oriented border research, the significance of borders in emergent disorder/order formations and border demarcations as examples of social disorder/order in European border regions, the EU’s and US’ migration systems, and virtual realities. This book makes an important contribution to the emerging complexity shift in current border studies. With contributions by Falk Bretschneider | Cécile Chamayou-Kuhn | Ulla Connor | Norbert Cyrus | Maria M. Fellner | Dominik Gerst | Guillaume Javourez | Rodrigo Bueno Lacy | Daniel Lambach | Carolin Leutloff-Grandits | Islam Rachi | Henk van Houtum | Christian Wille

Shifting B/Orders: Europeanization and Cross-Border Practices Between North Macedonia and Greece

Border Complexities and Logics of Dis/Order

Since the 2000s, the border between Greece and North Macedonia has undergone a progressive Europeanisation as an external border of the European Union. By looking at the regulations governing border control and the evolution of individual cross-border practices in regard of the local context in borderlands that long shared a common path, this paper questions the way in which the implementation of a new normative order reshuffles the configuration between social orders inherited from distinct historical periods and impact contemporary b/ordering processes.
