description: Introduction: In recent years, conflicts surrounding the use, distribution, and governance of surface water and groundwater in Germany have gained prominence in the media, on the political agenda, and in research. Increasing effects of climate change, such as heatwaves and drought but also extreme rain events and flooding, are considered to become more prominent and pressing in the future by different societal actors. However, it remains highly uncertain if and what type of conflicts related to water quantity Germany might actually face in the future (and how they will be framed). This paper addresses one dimension of this uncertainty - namely the future context uncertainty of possible resource and water governance conflicts. Our research contributes to an improved understanding of the uncertainty concerning future climatic, natural, land use related, political, economic, and other societal contexts that could impact water conflicts. Method: We ask: What are possible coherent context scenarios for Germany in the year 2050, and how are they expected to influence future water conflicts? In an expert-based process, we apply a qualitative and systematic method of systems analysis, cross-impact balances (CIB). With CIB, we build internally consistent scenarios of possible futures and map the future scenario space. Results and discussion: Diversity mapping with a new CIB web application of the ScenarioWizard reveals that the scenario space is rather large and diverse. The identified scenario space of n = 355 internally consistent scenarios spans four most diverse scenarios “Polycrisis,” “Economy and agriculture in crisis,” “Growth through adaptation to climate change,” and “Sustainable transformation.” Depending on the development of future contexts, the risk for future water resource and governance conflicts may unfold in various ways. We conclude that our scenario analysis provides a useful base for research and practice to address the context uncertainty of water conflicts in Germany. Our results can be used for risk assessment, to define societal framework assumptions for societal-hydrological modeling, and to develop robust and adaptive strategies and policies.

description: The Prytz planimeter is a simple example of a system governed by a non-holonomic constraint. It is unique among planimeters in that it measures something more subtle than area, combining the area, centroid and other moments of the region being measured, with weights depending on the length of the planimeter. As a tool for measuring area, it is most accurate for regions that are small relative to its length. The configuration space of the planimeter is a non-principal circle bundle acted on by SU(1,1), (isom. to SL(2,R)). The motion of the planimeter is realized as parallel translation for a connection on this bundle and for a connection on a principal SU(1,1)-bundle. The holonomy group is SU(1,1). As a consequence, the planimeter is an example of a system with a phase shift on the circle that is not a simple rotation. There is a qualitative difference in the holonomy when tracing large regions as opposed to small ones. Generic elements of SU(1,1) act on S^1 with two fixed points or with no fixed points. When tracing small regions, the holonomy acts without fixed points. Menzin's conjecture states (roughly) that if a planimeter of length L traces the boundary of a region with area A > pi L^2, then it exhibits an asymptotic behavior and the holonomy acts with two fixed points, one attracting and one repelling. This is obvious if the region is a disk, and intuitively plausible if the region is convex and A >> pi L^2. A proof of this conjecture is given for a special case, and the conjecture is shown to imply the isoperimetric inequality.

description: Automating the provisioning of 5G services, deployed over a heterogeneous infrastructure (in terms of domains, technologies, and management platforms), remains a complex task, yet driven by the constant need to provide end-to-end connections at network slices at reducing costs and service deployment time. At the same time, such services are increasingly conceived around interconnected functions and require allocation of computing, storage, and networking resources. The METRO-HAUL 5G research initiative acknowledges the need for automation and strives to develop an orchestration platform for services and resources that extends, integrates, and builds on top of existing approaches, macroscopically adopting Transport Software Defined Networking principles, and leveraging the programmability and open control of Transport SDN.

description: Digital platforms are transforming practices of political information production and circulation in local communities. We develop the theoretical concept of local political information infrastructure to draw attention to (1) the broadening array of actors who are producing political information in local communities, in addition to local news media, and (2) the role of network media logics in shaping everyday practices of political information production and circulation. We combine a computational analysis of Facebook posts from news and non-news community actors in a mid-sized Midwestern U.S. city with interviews with communication managers at local non-profits, libraries, local government, and city service organizations in that same case community. Our findings illustrate the ways in which local news media are increasingly displaced from the centre of local political information infrastructures, while Facebook moves to take up a central infrastructural role. We consider the consequences of these shifts for the circulation of politics and policy information in communities.

title: The post-fordist military: an inquiry into the political economy of private military comparnies.
Creators: name: Fulloon, Mark
Publisher: name: Griffith University
Year: 2013
Subjects: subject: Private Military Companies
subject: Post-Fordism
subject: Privatisation
subject: Military services

description: The rise and dominance of private military companies (PMCs) have become key factors in a number of conflicts since the end of the Cold War. This thesis is concerned about how the growth of PMCs is related to the changing modes of production from Fordism to post-Fordism. The changes in modes of production to post-Fordism highlights PMCs offering various military services in the current neo-classical economic environment, the outsourcing of military services, the privatisation and changing nature of war itself, and how PMCs are regulated in terms of their military operations and business structure. With this in mind, this thesis has researched PMC activity in parts of the world such as Iraq, Sierra Leone, Angola, Colombia, Afghanistan, Somalia, and the Democratic Republic of the Congo (DRC) to understand the strategic implications of this phenomenon. Furthermore, the thesis addresses various PMCs within the theatre of war, whether intra-state or inter-state and their roles in other military services not directly related to actual warfare but still have an influential impact and strategic influence on the structure of the armed forces. PMCs such as Executive Outcomes, Sandline International, Military Professional Resources Incorporated (MPRI), Control Risks Group, Cubic Defence, Erinys, Global Risk, DynCorp, Defence Services Limited (DSL), Blackwater USA, or Vinnell Corporation have played key roles in a variety of wars in the Third World from Afghanistan to Sierra Leone and most of the sub-Saharan African continent to Colombia in their drug wars, to the 2003 United States-led Iraq war. As this thesis will show, PMCs are a product of a series of post-Cold War environments in relation to post-Fordism that have led to a new military security paradigm in terms of the state, conflicts, and most defence forces around the globe. The activities of these PMCs have led scholars such as David Isenberg, Peter W. Singer, Deborah Avant, Anna Leander, Carlos Ortiz, Doug Brooks, David Shearer, or William Reno or Rita Abrahamsen to debate about whether or not these companies are a problem and hindrance in relation to state sovereignty, the monopoly on the use of legitimate violence and war, or whether PMCs are achieving results which organisations and countries cannot do, will not do, or are simply unable to.

description: In recent years, defect prediction techniques based on deep learning have become a prominent research topic in the field of software engineering. These techniques can identify potential defects without executing the code. However, existing approaches mostly concentrate on determining the presence of defects at the method-level code, lacking the ability to precisely classify specific defect categories. Consequently, this undermines the efficiency of developers in locating and rectifying defects. Furthermore, in practical software development, new projects often lack sufficient defect data to train high-accuracy deep learning models. Models trained on historical data from existing projects frequently struggle to achieve satisfactory generalization performance on new projects. Hence, this paper initially reformulates the traditional binary defect prediction task into a multi-label classification problem, employing defect categories described in the Common Weakness Enumeration (CWE) as fine-grained predictive labels. To enhance the model performance in cross-project scenarios, this paper proposes a multi-source domain adaptation framework that integrates adversarial training and attention mechanisms. Specifically, the proposed framework employs adversarial training to mitigate domain (i.e., software projects) discrepancies, and further utilizes domain-invariant features to capture feature correlations between each source domain and the target domain. Simultaneously, the proposed framework employs a weighted maximum mean discrepancy as an attention mechanism to minimize the representation distance between source and target domain features, facilitating model in learning more domain-independent features. The experiments on 8 real-world open-source projects show that the proposed approach achieves significant performance improvements compared to state-of-the-art baselines.

description: Recently, reconstruction-based anomaly detection was proposed as an effective technique to detect attacks in dynamic industrial control networks. Unlike classical network anomaly detectors that observe the network traffic, reconstruction-based detectors operate on the measured sensor data, leveraging physical process models learned a priori. In this work, we investigate different approaches to evade prior-work reconstruction-based anomaly detectors by manipulating sensor data so that the attack is concealed. We find that replay attacks (commonly assumed to be very strong) show bad performance (i.e., increasing the number of alarms) if the attacker is constrained to manipulate less than 95% of all features in the system, as hidden correlations between the features are not replicated well. To address this, we propose two novel attacks that manipulate a subset of the sensor readings, leveraging learned physical constraints of the system. Our attacks feature two different attacker models: A white box attacker, which uses an optimization approach with a detection oracle, and a black box attacker, which uses an autoencoder to translate anomalous data into normal data. We evaluate our implementation on two different datasets from the water distribution domain, showing that the detector's Recall drops from 0.68 to 0.12 by manipulating 4 sensors out of 82 in WADI dataset. In addition, we show that our black box attacks are transferable to different detectors: They work against autoencoder-, LSTM-, and CNN-based detectors. Finally, we implement and demonstrate our attacks on a real industrial testbed to demonstrate their feasibility in real-time.

description: This article traces the interconnection of the Bologna Process (BP) and the globalisation discourses which introduce a generic policy ensemble in European Higher Education (EHE). The two discourses appear as imbricated within an ideological understanding of the policy discourse. I explore similarities and controversies between the two discourses focusing particularly on knowledge economy driven policies and trends in higher education. Finally, I suggest that the high level of intertextuality between the globalisation and the discourses in their discursive construction permits us to consider them as interlocking and dependency discourses.

description: Rare earth based cobalt-ruthenium double perovskites A$_2$CoRuO$_6$ (A = La, Pr, Nd and Sm) were synthesized and investigated for their structural and magnetic properties. All the compounds crystallize in the monoclinic $P2_1/n$ structure with the indication of antisite disorder between Co and Ru sites. While, La compound is already reported to have an antiferromagnetic state below 27 K, the Pr, Nd and Sm systems are found to be ferrimagnetic below $T_c$ = 46, 55 and 78 K respectively. Field dependent magnetization data indicate prominent hysteresis loop below $T_c$ in the samples containing magnetic rare-earth ions, however magnetization does not saturate even at the highest applied fields. Our structural analysis indicates strong distortion in the Co-O-Ru bond angle, as La$^{3+}$ is replaced by smaller rare-earth ions such as Pr$^{3+}$, Nd$^{3+}$ and Sm$^{3+}$. The observed ferrimagnetism is possibly associated with the enhanced antiferromagnetic superexchange interaction in the Co-O-Ru pathway due to bond bending. The Pr, Nd and Sm samples also show small magnetocaloric effect with Nd sample showing highest value of magnitude $\sim$ 3 Jkg$^{-1}$K$^{-1}$ at 50 kOe. The change in entropy below 20 K is found to be positive in the Sm sample as compared to the negative value in the Nd counterpart.

description: The diffraction spectrum of coherent waves scattered from fractal supports is calculated exactly. The fractals considered are of the class generated iteratively by successive dilations and translations, and include generalizations of the Cantor set and Sierpinski carpet as special cases. Also randomized versions of these fractals are treated. The general result is that the diffraction intensities obey a strict recursion relation, and become self-affine in the limit of large iteration number, with a self-affinity exponent related directly to the fractal dimension of the scattering object. Applications include neutron scattering, x-rays, optical diffraction, magnetic resonance imaging, electron diffraction, and He scattering, which all display the same universal scaling.

A HIGH YIELD PROCESS FOR HYDRATE FORMATION
Creators: name: Giavarini, Carlo
name: Maccioni, Filippo
Publisher: name: The University of British Columbia
Year: 2008

description: A new procedure was studied to obtain concentrated methane hydrates in bulk, at medium-low pressure, avoiding the use of the spray process. Methane hydrate was formed at about 5 MPa and 2 °C in a reaction calorimeter with the volume of two liters. The clathrate concentration was about 30% and the final reactor pressure was 2.7 MPa. Any further repressurization at 2 °C had no noticeable effect on the hydrate formation. However, by repressurizing the vessel again to 4 MPa and increasing the temperature near the decomposition value (about 6° C) more clathrate was formed. Repressurizing again the reactor at 4 MPa and controlling the temperature at the same level, a concentration of 88% hydrate in the bulk was reached. Respect to the hydrate produced by the spray process, this procedure takes more time, but it can be sped up and made continuous by using teo reaction vessels, one for hydrate formation and the other for hydrate concentration. The advantage is the production of concentrated hydrates, by a simple equipment, working at relatively low pressures.

description: The study investigated the effect of systematic approach on students’ understanding of tonal values in painting in tertiary institutions. The study was designed to if syllabus B students (students without prior knowledge of art) will perform comparably to syllabus A (students that have prior knowledge of Fine Arts) in the correct application of tonal values. One research question and one hypothesis were put forward for the study. The design of this study was quasi-experimental and the non-equivalent control group design was used. Two intact classes were used, eight subjects in Syllabus B, and six in Syllabus A. The instrument for data collection was the painting tasks administered to the subjects. The results showed that the null hypothesis was retained implying that the performance of the two groups was comparable. The approach therefore, was not only effective, but improved beginning students understanding of painting.

description: Polyethersulfone (PSU) as a commercially available polymer offers many different opportunities for functionalization for diverse fields of application, for example, electrophilic substitutions like sulfonation and bromination or nucleophilic reactions such as lithiation. This study presents three different polysulfone derivatives, first functionalized by a lithiation reaction, followed by a reaction with carbonyl compounds containing pentafluorophenyl groups. In the last step, the pentafluorophenyl moieties of the modified PSU were sulfonated by thiolation and subsequent oxidation to sulfonic acid groups. Those novel PSU derivatives were characterized by NMR, DSC, TGA, GPC, and titration. Based on these ionomers, we show the fabrication of pure and acid-base blend membranes with promising proton conductivities. These novel sulfonic acid groups containing materials are potentially promising candidates for membranes or ionomers in electrochemical applications such as proton exchange membrane fuel cells (PEMFCs), proton exchange membrane water electrolysis (PEMWEs), or redox flow batteries (RFBs).

description: The adaptation of numerical wind wave models to the local time-spatial conditions is a problem that can be solved by using various calibration techniques. However, the obtained sets of physical parameters become over-tuned to specific events if there is a lack of observations. In this paper, we propose a robust evolutionary calibration approach that allows to build the stochastic ensemble of perturbed models and use it to achieve the trade-off between quality and robustness of the target model. The implemented robust ensemble-based evolutionary calibration (REBEC) approach was compared to the baseline SPEA2 algorithm in a set of experiments with the SWAN wind wave model configuration for the Kara Sea domain. Provided metrics for the set of scenarios confirm the effectiveness of the REBEC approach for the majority of calibration scenarios.

description: Ubiquitous computing describes computing technologies that are designed to be embedded in tools and in our environment, providing computational support for user interaction and service delivery. Intelligent environments are context-aware computing environments that deliver services using ubiquitous computing technologies. These environments provide users with services tailored to the users’ preferences and the current state of the environment. The development and implementation of these environments is challenging due to their potential ability to gather information on the environment’s occupants and context. The information collection, when combined with advanced data-mining techniques, has unprecedented potential to invade users’ privacy. The invasion of privacy is a significant concern to users, and must be addressed before intelligent environments can gain widespread acceptance. The use of ubiquitous computing technologies also poses unique challenges for service delivery and network security. By definition, ubiquitous computing describes computing that has faded into the background, allowing users to use the services and technologies as easily as they would more tangible physical objects. This integration into our world raises the question that if a service is inconspicuous enough to blend into the background, how can we allow users to identify previously unused services? Information security within intelligent environments is complicated by the physical availability of much of the environment’s hardware (which leaves it vulnerable to being tampered with). These privacy and security concerns raise the need for a ubiquitous computing infrastructure that will allow private interaction and the effective delivery of personalised and identity-restricted services. Owing to the large variety of services they could provide, it has been suggested that intelligent environments will one day cover most of our daily lives (for example our homes, offices, public transport networks or shopping centres). This requires a common approach be taken to users’ interaction with intelligent environments, and suggests a shared infrastructure will be required to support users’ interactions with different environments. User privacy requirements necessitate that this infrastructure be independently operated from the intelligent environments (and its service providers). Further privacy and interaction requirements highlight the need for user-controlled identity management structures and anonymous environmental interaction.

description: Decision trees are flexible models that are well suited for many statistical regression problems. In a Bayesian framework for regression trees, Markov Chain Monte Carlo (MCMC) search algorithms are required to generate samples of tree models according to their posterior probabilities. The critical component of such an MCMC algorithm is to construct good Metropolis-Hastings steps for updating the tree topology. However, such algorithms frequently suffering from local mode stickiness and poor mixing. As a result, the algorithms are slow to converge. Hitherto, authors have primarily used discrete-time birth/death mechanisms for Bayesian (sums of) regression tree models to explore the model space. These algorithms are efficient only if the acceptance rate is high which is not always the case. Here we overcome this issue by developing a new search algorithm which is based on a continuous-time birth-death Markov process. This search algorithm explores the model space by jumping between parameter spaces corresponding to different tree structures. In the proposed algorithm, the moves between models are always accepted which can dramatically improve the convergence and mixing properties of the MCMC algorithm. We provide theoretical support of the algorithm for Bayesian regression tree models and demonstrate its performance.

description: Electrochemical impedance spectroscopy (EIS) is a powerful tool commonly used to study electrochemical systems. Nevertheless, its application in CO2 electroreduction has been so far limited due to its complex reaction mechanism and environment. Although initial findings have demonstrated the viability of applying EIS analysis in CO2 electrolyzers, the assignment of individual processes in the impedance spectra remains ambiguous. Therefore, a more detailed investigation, especially focused on its application in evaluating degradation mechanisms, is essential. In this study, a stable gas diffusion electrode (GDE) system was developed for a comprehensive EIS and distribution of relaxation time (DRT) evaluation to assess key degradation mechanisms under accelerated stress conditions such as high current density and low operating temperature. Validated by post-mortem analysis and complementary methods, we demonstrate the viability of this approach for operando monitoring of CO2 electroreduction by assigning individual mechanistic processes in the GDE and linking them to performance degradation over time.

description: The recent development and deployment of HYACINTH and IODP PCS pressure cores on the JOIDES Resolution during Expedition 1 of the Indian National Gas Hydrate Program (NGHP-1) has provided some of the first “undisturbed” samples of gas hydrate in fine grained marine sediments. Some samples, once recovered from the seafloor, were subject to rapid depressurization and subsequent immersion in liquid nitrogen, at approximately -196oC, for use in subsequent laboratory test programs. This paper describes the techniques used at Southampton University, the difficulties encountered, and the results obtained from geotechnical testing of these samples. The original intention had been to pressurize and unfreeze the material before testing it in the Gas Hydrate Resonant Column (GHRC) Apparatus. Initial CT scanning of the samples showed that the sample quality might be too poor for such testing, and this proved to be the case. Instead a suite of geotechnical testing was carried out, the results of which are reported and interpreted in this paper.
Determinant map for the prestack of Tate objects

description: We construct a map from the prestack of Tate objects over a commutative ring $k$ to the stack of $\mathbb{G}_{\rm m}$-gerbes. The result is obtained by combining the determinant map from the stack of perfect complexes as proposed by Schürg-Toën-Vezzosi with a relative $S_{\bullet}$-construction for Tate objects as studied by Braunling-Groechenig-Wolfson. Along the way we prove a result about the K-theory of vector bundles over a connective $\mathbb{E}_{\infty}$-ring spectrum which is possibly of independent interest.

Evaluating State Based Economic Development Policy: Learning from Atlantic City

Economic development--Government policy

description: Economic development planning has increasingly become a primary function of state governments. Imbued with extensive powers, state economic development authorities and other special entities utilize incentives and other techniques to attract and retain businesses within a community in order to bring increased growth, jobs and tax revenues. However, the economic development planning undertaken by these organizations often lacks rigorous evaluation methods or concrete development goals, with state agencies instead going about economic development with good intentions, but bad practices. This is troubling because these entities utilize vast sums of state revenue and expansive powers, such as eminent domain, to engage in economic development without a clear understanding of what the outcomes and impacts of state actions will be.
	Atlantic City, New Jersey serves as a unique case study for this form of economic development. Since the legalization of casino gaming in the city in 1976, the State of New Jersey has been heavily involved in the development of the city’s economy and has engaged in large-scale urban renewal programming as a form of economic development. Through a variety of agencies, including the Casino Reinvestment Development Authority and New Jersey Economic Development Authority, the State has utilized a variety of economic development practices including eminent domain, tax credits and incentives to go about the redevelopment of Atlantic City.
	Through the exploration of three specific development programs undertaken by the State: eminent domain, financial incentives, and public-private partnerships, this thesis critically evaluates the economic policies of the State of New Jersey in order to provide detailed analysis of the impacts and outcomes of these policies, including those traditionally overlooked by economic development practitioners. Ultimately, concluding that the State’s use of economic development planning has been inadequate and at times run contrary to a holistic economic development strategy intended to uplift a very depressed and economically disadvantaged Atlantic City.

description: Data stream mining, also known as stream learning, is a growing area which deals with learning from high-speed arriving data. Its relevance has surged recently due to its wide range of applicability, such as, critical infrastructure monitoring, social media analysis, and recommender systems. The design of stream learning methods faces significant research challenges; from the nonstationary nature of the data (referred to as concept drift) and the fact that data streams are typically not annotated with the ground truth, to the requirement that such methods should process large amounts of data in real-time with limited memory. This work proposes the SiameseDuo++ method, which uses active learning to automatically select instances for a human expert to label according to a budget. Specifically, it incrementally trains two siamese neural networks which operate in synergy, augmented by generated examples. Both the proposed active learning strategy and augmentation operate in the latent space. SiameseDuo++ addresses the aforementioned challenges by operating with limited memory and limited labelling budget. Simulation experiments show that the proposed method outperforms strong baselines and state-of-the-art methods in terms of learning speed and/or performance. To promote open science we publicly release our code and datasets.
Nominalization, abstraction and technicality in History and Physical Science: some evidence from Greek primary school textbooks

description: The aim of this paper is to analyse Greek primary school textbooks of History and Physical Science in terms of their abstraction and technicality, which - following Systemic Functional Linguistics - characterize educational knowledge, mainly based on written language. Written texts reconstruct experience into specialized knowledge through the grammatical metaphor of nominalization, which is considered to be strongly related to the recontextualization of oral mode to written mode. Moreover, research on secondary education school texts has shown relevant variety between Physical Science and History texts by means of lexicogrammatical choices employed. But, since relevant research stresses the importance of grammatical metaphor in secondary education, our attempt in this paper is to illustrate some facets of the same phenomenon in Greek primary education textbooks. More specifically, our aim is to analyse some Greek textbooks of History and Physical Science in terms of nominalization in order to account for its ways to pattern specialized fields, according both to grades (A΄ to F΄) and to different school disciplines.
