Scotland’s international competitiveness within Western Europe
No full textThe paper measures regional competitiveness of Scotland in comparison to ten EU regions and small countries using the International Benchmarking Index Family (‘IB Index Family’) developed by BAK Basel Economics.1 The IB Index Family contains an index with three dimensions of competitiveness: Performance, Attractiveness and Structural Potential. The Performance Index measures recent economic success; the Attractiveness Index measures how well a region is an attractive location to companies and highly-qualified individuals; and the Structural Potential Index estimates future potential economic growth based on current economic structure. The application of the IB Index Family provides a first-step into a more in-depth benchmarking of the competitiveness of a region, which is necessary when working towards detailed policy conclusions. The paper explains these measurement tools and applies them in a short benchmarking analysis of Scotland and ten EU regions and small nations (e.g. Ireland, Norway, Western Sweden etc.)
La responsabilità internazionale degli Stati per attacchi informatici internazionalmente illeciti sferrati in tempo di pace
No full textThis article aims to examine the international responsibility of States for internationally wrongful cyber attacks in times of peace in light of the 2001 Draft Articles of the International Law Commission on State Responsibility for Wrongful Acts and of Chapter 4 of the Tallinn Manual 2.0 with particular regard to the constitutive elements of State responsibility, the circumstances precluding wrongfulness, the consequences of an internationally wrongful cyber attack and the measures of self-help which may be used by the target State. In order to establish the circumstances in which a cyber attack may lead to the breach of the primary norms of international law, the article analyses the difficult and debated issue of when a State-sponsored cyber attack reaches the threshold of an infringement of sovereignty, of the principle of non-intervention and of the prohibited «use of force» under art. 2(4) of the un Charter. This contribution has shown that most State-sponsored cyber attacks may violate the sovereignty of the targeted State as well as the principle of non-intervention but may fall below the threshold of the «use of force», the sole exception being the 2010 Stuxnet cyber attack allegedly perpetrated by the United States and Israel against the centrifuges of an Iranian nuclear facility. Further issues arise with regard to the threshold of an «armed attack» in order for the targeted State to use kinetic or cyber force in self-defence pursuant to art. 51 of the un Charter. Since the adaptation of said existing rules of international law to the cyber context may be problematic, the author advocates for the elaboration by the International Law Commission of a Draft Articles on State Responsibility for Internationally Wrongful Cyber Attacks and the subsequent adoption of an international convention which may also include a specific Chapter concerning the breach by State-sponsored cyber attacks of specific norms of international law, including in particular jus contra bellum
Von der Nekropole zum Siedlungsplatz. Bericht über die Grabungskampagnen 2018 und 2019 in der Petosiris-Nekropole von Tuna el-Gebel
No full textAusgrabungen und Georadarmessungen in der Nekropole Tuna el-Gebel haben 2018 und 2019 neue Erkenntnisse über das Areal ergeben. Teilweise freigelegt wurden ein Steinbau (GB 73) und ein Gebäude aus ungebrannten Lehmziegeln (GB 72). Der Steinbau wurde in der Kaiserzeit als Grabbau genutzt, darüber hinaus verweist die Keramik auf eine Nachnutzung in der Spätantike. Die Anzahl und die Typen der Gefäße sprechen für die Ansiedlung einer größeren Gruppe von Menschen. GB 72 war zweistöckig und verfügte über ungewöhnliche Kultinstallationen vor der Fassade, die im Grabkontext zu deuten sind. Die Architektur verweist zudem auf eine diverse Nutzung des Gebäudes, etwa als Grabhaus und Einbalsamierungsstätte. Die geophysikalische Prospektion erschloss den östlichen Teil der Nekropole und ergänzte den Survey von 2007 und 2010. Die hohe Auflösung und die Kombination der Methoden ermöglichen eine genaue Differenzierung der Gebäudetypen sowie die Erstellung detaillierter Pläne der Nekropole. Zudem sind in den Radargrammen Störungen zu erkennen, die von Grabräubern herrühren.Excavations and georadar measurements in the Tuna el-Gebel necropolis in 2018 and 2019 have revealed new information about the site. A stone building (GB 73) and a building made of adobe bricks (GB 72) were partially exposed. The stone building was used as a tomb in the imperial period; moreover, the ceramics indicate a subsequent use in late antiquity. The number and types of vessels suggest the settlement of a larger group of people. GB 72 had two storeys and provided unusual cult installations in front of the façade, which are to be interpreted as belonging to the funerary context. According to the architecture the building had various uses, for instance as a tomb and an embalming place. The geophysical prospection was carried out in the eastern part of the necropolis and supplemented the survey of 2007 and 2010. The high resolution and the combination of methods permit a precise differentiation of the building types as well as the creation of detailed maps of the necropolis. In addition, the radargrams show disturbances caused by grave robbers
Einfluss der synoptischen Situation auf die Validierung von Niederschlägen aus Satellitendaten über der Ostsee
No full textThe objective of this thesis is to verify the qualitative and quantitative influence of the weather on precipitation data over the Baltic Sea, derived from the HOAPS climatology (Hamburg Ocean Atmosphere Parameters and fluxes from Satellite Data), and to analyze the synoptic phenomena that may influence the probability of HOAPS to detect precipitation. For this purpose, precipitation data of the HOAPS climatology derived from satellite measurements as well as in-situ-precipitation measurements by ship rain gauges on board of merchant ships, both taken in a period between 1995 and 1997, are available. The data set is collocated; the HOAPS- and the rain gauge measurements are separated by 30 minutes and 25 kilometers at most. In order to analyze the weather conditions, the prognostic Europamodell of the DWD as well as surface pressure charts and satellite images were used. On average, HOAPS detects 55% of all precipitation events having precipitation rates greater equal 0.3mm/h that are identified by the ship rain gauges as well. The comparison of the precipitation data leads to the conclusion that HOAPS underestimates the measured precipitation; the inclusion of weather charts and satellite images shows that this is independent of the type of precipitation. Moreover, the probability of HOAPS to identify precipitation rises when precipitation rates rise. The investigation of cloud types, pressure fields and frontal systems shows that the probability of HOAPS to detect precipitation is smaller during convective than during stratiform clouds; correspondingly, a passage of a cold front also decreases the probability of HOAPS to identify precipitation. Thus, it may be concluded that HOAPS misses short-period precipitation like showers more often than long-lasting, stratiform precipitation

Book Review: Remaking Memory : Autoethnography, memoir and the ethics of self John Freeman With contributions by Rebekka Kill, Nazar Jabour, Kate Rice, Steph Brocken and Jamie Coull
No full textJohn Freeman’s Remaking Memory: Autoethnography, memoir and the ethics of self makes a significant contribution to autoethnography and memoir. The book includes a lengthy chapter on autoethnographic performance that draws upon literary and performance works pertaining to self-narrating practices. Five case studies by postgraduate students are also included in order to ‘remind the reader [and author] that a sole authorial voice is usually suspect’ (13) and to provide first-hand accounts of some of the ways in which performance and autoethnography have been applied within specific research contexts. Case studies by Rebekka Kill (UK), Nazar Jabour (Iraq/Australia), Kate Rice (Australia), Steph Brocken (UK) and Jamie Coull (Australia) stem directly from the graduate researchers’ theses, offering rich insight into transnational questions of methodology and modes of presentation

Session D1: Classification of Flow Patterns in a Nature-Oriented Fishway Based on 3D Hydraulic Simulation Results
No full textPresenting Author Bio: Rebekka Czerny is a scientific assistant at Institute for Water and River Basin Management, Karlsruhe Institute of Technology (KIT). She studied Civil Engineering in Karlsruhe (major fields of study: hydraulic engineering and water management) and now works in the field of hydraulic simulation. Rebekka Czerny has been working on numerous projects concerning flood simulation, hydraulic simulation of rivers with automated barrage control, and high resolution hydraulic simulation. Her doctoral research study deals with detailed flow simulation of nature-oriented streams based on high resolution topographical data acquired by terrestrial laser scanning.Abstract: In order to fulfill the requirements of the EU Water Framework Directive concerning the restoration of fish passage in rivers, various types of (near-natural and technical) fishways have been built in recent years. For optimization of planned structures as well as for monitoring of the performance of existing fishways, their hydraulics has to be studied. 3D hydrodynamic numerical modelling is a useful tool to predict hydraulic quantities and analyse flow pattern. Many studies using hydraulic simulations deal with technical fishways. In contrast, nature-oriented fishways have rarely been numerically modelled so far. In the framework of R&D activities at Karlsruhe Institute of Technology, a high resolution 3D-hydraulic model of a section of a nature-oriented bypass channel (rock cascade pass) has been developed. The basis of a hydraulic model is a 3D-model of the fishway’s topography. Since fishways of a nature-oriented design type are characterized by highly irregular structures, the build-up of such a model is very challenging. In this study, the method of terrestrial laser scanning was used for detailed geodata acquisition. The hydraulic model was validated using, inter alia, acoustic Doppler velocity measurements. Simulations using the computational fluid dynamics software FLOW-3D were performed for two hydraulic scenarios. The simulated hydraulic quantities (velocities, water levels) and their distribution along the vertical and horizontal axes have been investigated and compared to critical values concerning fish passability specified in technical standards. A method of categorization of flow patterns is proposed, which enables a schematic visualization of complex flow conditions. In this way, potentially critical zones can be located and specific flow patterns can be identified. This method of analysis has a high potential in terms of addressing environmental issues concerning nature-oriented fishways and river restoration projects
3D knitting for transformable, load-bearing structures
No full textThis research-through-design explores 3D knitting for load-bearing, transformable structures using a Material-Driven Design approach. 3D knitting is a low-waste textile production method that allows for highly adaptable designs and an iterative design process. Current literature is studied in various domains, exhibiting the knowledge gap on development of 3D knitted, load-bearing, transformable structures on the scale of a sitting object. A tinkering phase resulted in a Design Space, demonstrating the range of possible materials, structures, geometries and transformability methods. Multiple concepts are developed to define the relationship between the parameters. The final demonstrator is the ARCHETYPE.98, a sitting object showing the adaptability, load-bearing capacity, transformability, material expressions and streamlined, low-waste production process of 3D knitted, transformable, load-bearing objects. The ARCHETYPE.98 is a bending-active textile hybrid structure. The load-bearing capacity is evaluated through a technical evaluation which exhibited the framework material to require improvement. User research exhibited the novelty of the design. The transformability of the sitting objects allows for eight variations of the aesthetics within one product. The sitting surfaces are highly adaptable through the knitted material, enabling personalization of the aesthetics and ergonomics of the chair. The development and production process of the ARCHETYPE.98 show the need for modelling software for knit structures and textile hybrid structures to improve the technical performance and reduce the number of required iterations. Further research into the frame material and bursting strength of knit structures related to the yarn materials could improve the load-bearing capacities of the object and bring forward the limitations of the applied rigidifying method.Integrated Product Desig
