description: Internet browsers use security protocols to protect sensitive messages. An inductive analysis of TLS (a descendant of SSL 3.0) has been performed using the theorem prover Isabelle. Proofs are based on higher-order logic and make no assumptions concerning beliefs or finiteness. All the obvious security goals can be proved; session resumption appears to be secure even if old session keys have been compromised. The proofs suggest minor changes to simplify the analysis. TLS, even at an abstract level, is much more complicated than most protocols that researchers have verified. Session keys are negotiated rather than distributed, and the protocol has many optional parts. Nevertheless, the resources needed to verify TLS are modest: six man-weeks of effort and three minutes of processor time.

description: The dominant perspective in discussions of labor and environmental standards and globalization is that of North-South competition and its impact on Northern standards. This paper presents an alternative perspective, that of South-South competition to export to the North, and its impact on Southern standards. It develops a simple model of Southern competition on standards, which can begin to provide insights into some key questions. A Southern race to the bottom is possible but not inevitable. It depends intricately on the Northern demand curve, the size of big exporters relative to each other, and the relative size of the competitive fringe of small exporters { a precise and complete characterization is developed in the paper. The paper also analyzes the e®ect of Northern tari®s on Southern strategic competition in standards. It is shown that Northern trade protectionism undermines Southern standards.
Der Islam der Medienschaffenden. Eine qualitative und rassismustheoretische Analyse

description: Spätestens mit der Iranischen Revolution 1979 entdeckten die Medien den Islam als Gegenstand der Berichterstattung. Seither sind Inszenierungen des Islam als bedrohlich ebenso Teil medialer Präsentationen wie eine Kritik an seiner eindimensionalen Darstellung. Der vorliegende Beitrag befasst sich aus rassismustheoretischer Perspektive und auf Basis empirischer Befunde mit der Frage, wie diskursgestaltende Medienschaffende diese Inszenierungen wahrnehmen. Die Analyse zeigt, dass Medienschaffende zwar eine differenzierte Kritik antizipieren, aber dennoch Zugeständnisse an eine Leser: innenschaft machen, die ihnen Verharmlosungen islamistischer Gewalt vorwirft. Populistische Debatten um ›Lügenpresse‹ und ›Systemmedien‹ bleiben für Journalist:innen nicht ohne soziale Konsequenzen. Sie fürchten um ihre Rolle als ›Gatekeeper‹ angesichts einer Pluralisierung der Medienlandschaft und des Aufschwungs rechter politischer Parteien und Strömungen sowie deren medialer Stimmungsmache. Die Befunde belegen antidemokratische Entwicklungen der ›vierten Gewalt‹ und weisen auf Gefährdungen ihres emanzipatorischen Auftrags hin. The Islam of Media Professionals. A Qualitative Analysis of Journalistic Perspectives Based on Critical Theorizations of Racism In the wake of the Iranian Revolution 1979, at the very latest, media discovered Islam as a subject of reporting. By now, in Germany, the representation and staging of Islam as a threat is just as much part of media reporting as criticism of its one‐dimensional portrayal. Based on empirical findings and critical theorizations of racism, this article investigates how discourseshaping media professionals perceive this staging of a ›threat of Islam‹. The analysis shows that media professionals, while anticipating nuanced criticism, nevertheless make concessions to a readership that accuses them of trivializing militant Islamist violence. Populist debates about the ›lying press‹ and ›system media‹ are not without social consequences for journalists. They fear for their role as ›gatekeepers‹ in the face of a pluralization of the media landscape and the rise of right-wing political parties and currents as well as their media sensationalism. The findings show anti-democratic developments within the ›fourth power‹ and indicate threats to its emancipatory mission.

description: A structural model is developed to simulate the probability distributions of corn prices by month. The intent is to determine the relationship between model specifications, based on a rational expectations competitive storage framework, and the probability distributions of monthly prices. Specifically, can a structural model generate corn prices with characteristics that are consistent with those observed in the 1990s? The model in this paper produces cash prices that inter alia have positively skewed distributions where the mean and variance increase over the storage season. The model also generates futures prices as conditional expectations of spot prices at contract maturity. The variances of these futures prices have realistic time-to-maturity and seasonal effects. The model is solved and simulated so that the consequences of making the model increasingly complex can be determined. A “curse of dimensionality” is inevitable with the increased complexity, resulting in lengthy computing times, but the final specification generates plausible probability distributions. In contrast to other models in the literature, our specification does not depend on the unrealistic assumption of zero stock-levels to generate skewed price distributions and the Abackwardation@ commonly observed in prices between crop years. Non-linearity in the supply of storage is achieved by modeling convenience yield. The model can be used to depict price behavior conditional on varying levels of the state variables, e.g., for large or small stock levels. Having created realistic probability distributions of prices, a logical next step is to use the distributions to appraise marketing strategies to manage price risk for corn.

description: This paper surveys the main income distribution implications of greater openness in the African context. It considers trade, capital flows, technology, risk, and the ethnic dimension. It argues that the central policy dilemma for African policy makers is how to take advantage ofthe undoubted opportunities that integration into the world economy affords for rapid growth, while managing the attendant risks for domestic income distribution in its different dimensions. It proposes a research and policy agenda to further illuminate the options and tradeoffs they face.

description: In the presence of international public goods, donors are faced with two instruments whereby recipient utility may be altered -contributions towards the international public good and direct transfers (conventional foreign aid). The self-interested donor's optimal choice of transfer-contributions combinations will typically depend upon the public goods technology. Some technologies call for a corner solution, with either transfers or contributions set to zero, and others are characterised by interior solutions, where the donor's optimal strategy calls for a positive transfers and positive contributions. Whether or not the presence of an international public good strengthens the case for conventional foreign liid transfers is therefore not always obvious.

description: Australia's foreign policy may be drafted in Canberra, but it is implemented in the jungles of Java and the bazaars of Dar-es-Salaam, as well as in the offices and boardrooms in Washington, London or Bonn. The aim of this sub-thesis is to examine the role of the Snowy Mountains Engineering Corporation (SMEC) as an instrumentality for the practical implementation of Australia's foreign policy, particularly in relation to developing countries, and more specifically in the AsiaPacific Region. Towards this end a comparison and contrast will be made of two SMEC overseas projects. As well as covering some specific details, it is hoped that these two case studies will present SMEC's overseas operations in microcosm.

description: This paper suggests a framework for analyzing aid dependence, particularly in Africa. It argues that aid dependence, and not necessarily a low volume of assistance, is the major problem. It considers the context of the micro-institutional mechanisms of aid delivery, and the context of the macro-dynamics of aid. It proposes specific institutional remedies, and sets out questions that country specific analyses of aid dependence should attempt, to answer.

description: A detailed study of orbital and radial excited states in D, Ds, B and B_s systems is performed. The chiral quark model provides the framework for the calculation of pseudoscalar meson (pi, K, ...) hadronic transitions among heavy-light excited and ground states. To calculate the excited states masses and wavefunctions, we must resort to a relativistic quark model. Our model includes the leading order corrections in 1/m_(c,b) (e.g. mixing). Numerical results for masses and light hadronic transition rates are compared to existing experimental data. The effective coupling of the chiral quark model can be determined by comparing with independent results from lattice simulations (g^8_A = 0.53 +-/- 0.11) or fitting to known widths (g^8_A = 0.82 +-/- 0.09).

Preliminary results on the first moment of the structure function g_1(x,Q^2) for protons, and on the generalized Gerasimov-Drell-Hearn integral for neutrons are presented as well. The first moment for protons shows a strong Q^2 dependence below Q^2 = 1 GeV^2, and changes sign near Q^2 = 0.3 GeV^2. Strong double polarization asymmetries are observed in exclusive electroproduction of pions from polarized protons.

Decolonizing Migration Studies? Thinking about Migration Studies from the Margins
Creators: name: Kosnick, Kira
Publisher: name: Journal of Migration Studies
Year: 2021

description: Against the background of calls to ›decolonize knowledge‹ in migration studies as in different academic fields, this article addresses the conditions under which knowledge on migration is produced at German universities. Noting that refugee scholars and those with migration backgrounds from outside Western Europe or North America face specific difficulties in pursuing academic careers, a ›coloniality of migration‹ framework is employed to examine how different groups are differentially integrated into the German academic system. Suggesting a self-reflexive focus on the conditions for academic research at higher education institutions, it is argued that the conditions under which a heterogeneous ›we‹ performs the work of migration studies are differentially implicated in the governmental curtailment and management of migration and (post)migrant subjects, and in global unequal forms of hegemonic knowledge production. Migrationsforschung dekolonialisieren? Überlegungen zur Migrationsforschung und ihren Rändern Vor dem Hintergrund von Forderungen nach einer ›Dekolonisierung des Wissens‹ in der Migrationsforschung, aber auch in anderen wissenschaftlichen Feldern thematisiert dieser Beitrag die Bedingungen, unter denen Wissensproduktion zu Migration an deutschen Universitäten stattfindet. Angesichts der besonderen Schwierigkeiten, mit denen geflüchtete Wissenschaftler* innen, aber auch jene mit Migrationshintergründen aus Ländern jenseits von Westeuropa oder Nordamerika auf ihrem akademischen Karriereweg konfrontiert sind, wird der ›coloniality of migration‹-Ansatz genutzt, um die differenzielle Integration verschiedener Gruppen in das deutsche Wissenschaftssystem zu untersuchen. Im Zuge einer selbstreflexiven Thematisierung der Produktionsbedingungen von Forschung an Hochschulen wird argumentiert, dass die Bedingungen, unter denen ein heterogenes ›Wir‹ die Arbeit der Migrationsforschung betreibt, mit der gouvernementalen Regulierung von Migration und (post)migrantischen Subjekten verknüpft sind sowie mit global ungleichen Formen hegemonialer Wissensproduktion.

description: The interplay between crystal nucleation and the structure of the metastable fluid has been a topic of significant debate over recent years. In particular, it has been suggested that even in simple model systems such as hard or charged colloids, crystal nucleation might be foreshadowed by significant fluctuations in local structure around the location where the first nucleus arises. We investigate this using computer simulations of spontaneous nucleation events in both hard and charged colloidal particles. To detect local structural variations, we use both standard and unsupervised machine learning methods capable of finding hidden structures in the metastable fluid phase. We track numerous nucleation events for the face-centered cubic and body-centered cubic crystal on a local level, and demonstrate that all signs of crystallinity emerge simultaneously from the very start of the nucleation process. We thus conclude that there is no precursor for the nucleation of charged colloids.

description: Detached eclipsing binaries are remarkable systems to provide accurate fundamental stellar parameters. The fundamental stellar parameters and the metallicity values of stellar systems are needed to deeply understand the stellar evolution and formation. In this study, we focus on the detailed spectroscopic and photometric studies of three detached eclipsing binary systems, V372\,And, V2080\,Cyg, and CF\,Lyn to obtain their accurate stellar, atmospheric parameters,and chemical compositions. An analysis of light and radial velocity curves was carried out to derive the orbital and stellar parameters. The disentangled spectra of component stars were obtained for the spectroscopic analysis. Final \teff, \logg, $ξ$, \vsini\, parameters and the element abundances of component stars were derived by using the spectrum synthesis method. The fundamental stellar parameters were determined with a high certainty for V372\,And, V2080\,Cyg ($\sim$$1-2$\%) and with an accuracy for CF\,Lyn ($\sim$$2-6$\%). The evolutionary status of the systems was examined and their ages were obtained. It was found that the component stars of V2080\,Cyg have similar iron abundance which is slightly lower than solar iron abundance. Additionally, we showed that the primary component of CF\,Lyn exhibits a non-spherical shape with its 80\% Roche lobe filling factor. It could be estimated that CF\,Lyn will start its first Roche overflow in the next 0.02\,Gyr.

Matroid lifts and representability

Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: A 1965 result of Crapo shows that every elementary lift of a matroid $M$ can be constructed from a linear class of circuits of $M$. In a recent paper, Walsh generalized this construction by defining a rank-$k$ lift of a matroid $M$ given a rank-$k$ matroid $N$ on the set of circuits of $M$, and conjectured that all matroid lifts can be obtained in this way. In this sequel paper we simplify Walsh's construction and show that this conjecture is true for representable matroids but is false in general. This gives a new way to certify that a particular matroid is non-representable, which we use to construct new classes of non-representable matroids.
 Walsh also applied the new matroid lift construction to gain graphs over the additive group of a non-prime finite field, generalizing a construction of Zaslavsky for these special groups. He conjectured that this construction is possible on three or more vertices only for the additive group of a non-prime finite field. We show that this conjecture holds for four or more vertices, but fails for exactly three.
Quantum fast Fourier transform using multilevel atoms

Subjects: subject: Quantum Physics (quant-ph)

description: We propose an implementation of the quantum fast Fourier transform algorithm in an entangled system of multilevel atoms. The Fourier transform occurs naturally in the unitary time evolution of energy eigenstates and is used to define an alternate wave-packet basis for quantum information in the atom. A change of basis from energy levels to wave packets amounts to a discrete quantum Fourier transform within each atom. The algorithm then reduces to a series of conditional phase transforms between two entangled atoms in mixed energy and wave-packet bases. We show how to implement such transforms using wave-packet control of the internal states of the ions in the linear ion-trap scheme for quantum computing.

description: A methodology with which to analyze the welfare distributional effects of food pricing policy reforms is proposed, critically investigated and refined using Indonesian household level data. The problems of welfare measurement dealt with include the need for behavioral consistency and the making of interpersonal comparisons of welfare when household specific circumstances vary. Building on recent advances in empirical tax reform analysis, an equivalent income function is used as the welfare indicator. This is constructed from the explicit indirect utility function underlying the functional form used in the econometric modelling of consumer demands for rice and housing on 1981 SUSENAS data for Java. Normalizing for spatial price differentials and for variations in demographic characteristics is found to result in a reduction in measured welfare inequality. The methodology is used to explore the welfare consequences of spatial domestic rice market integration and of across the board price level changes, as would be expected to result following an external trade liberalization of Indonesia's rice markets. The reforms are simulated under various assumptions concerning the producer and consumer income effects of the price changes. The thesis also investigates alternative public compensation schemes implemented through the input subsidies policy or by means of lump-sum transfers targeted at producers and/or consumers. The elimination of spatial rice price differentials is found to have modest potential social gains while exacerbating inequality. Rice price rises are assessed to have beneficial welfare distributional effects if accompanied by, for example, a scenario which implements cuts in input subsidies and redistributes the resulting fiscal benefits as lump-sum transfers to all households. Of fundamental concern throughout the thesis are questions about how alternative assumptions adopted in constructing the equivalent income function affect the ordinal ranking of households in the pre-reform situation and the social welfare orderings of the policy reforms. Sensitivity to the choice of functional form and reference prices, to the number of included goods and to the treatment of the regression errors are examined. The overall social welfare evaluations of policy reforms are found to be generally robust to such variations. Conversely, the welfare ranking of households appears to be quite sensitive.

description: Though the minimal model of anomaly mediated supersymmetry breaking has been significantly constrained by recent experimental and theoretical work, there are still allowed regions of the parameter space for moderate to large values of $\tanβ$. We show that these regions will be comprehensively probed in a ${\sqrt s} =1$ TeV $e^+e^-$ linear collider. Diagnostic signals to this end are studied by zeroing in on a unique and distinct feature of a large class of models in this genre: a neutral winolike Lightest Supersymmetric Particle closely degenerate in mass with a winolike chargino. The pair production processes $e^+e^- \to {\tilde e}_L^\pm {\tilde e}_L^\mp$, ${\tilde e}_R^\pm {\tilde e}_R^\mp$, ${\tilde e}_L^\pm {\tilde e}_R^\mp$, ${\tilde ν} {\bar {\tilde ν}}$, $\widetilde χ^0_1 \widetilde χ^0_2$, $\widetilde χ^0_2 \widetilde χ^0_2$ are all considered at $\sqrt s = 1$ TeV corresponding to the proposed TESLA linear collider in two natural categories of mass ordering in the sparticle spectra. The signals analysed comprise multiple combinations of fast charged leptons (any of which can act as the trigger) plus displaced vertices $X_D$ (any of which can be identified by a heavy ionizing track terminating in the detector) and/or associated soft pions with characteristic momentum distributions.

Public Discourses and Politics on Migration: A Precarious Situation and Dismal Outlook?

description: Emotions dominating normative frameworks is not new in the making of migration-related policies or in public discourses on migration. However, this matter has entered a different dimension in the age of populism and post-factualism reshuffling the parameters of this issue to a large extent. I will argue in this article that we can find a mixture of developments that consecutively reveals a state of public discourses that is highly precarious and that needs change and counteraction. Instead of retreating into welltrodden policy issues and overtly neglecting the potentiality for a constructive discourse that includes the deliberation on migration realties and migratory processes and its complexities, a vision is needed for new evidencebased, well-informed, yet not technocratic, forms of discourse and a future of reflexive knowledge production. Öffentliche Diskurse und Migrationspolitik: Eine prekäre Situation und ein düsterer Ausblick? Die Prägung politischer und öffentlicher Migrationsdiskurse durch Emotionen und Normativität ist nicht neu. Im Zeitalter von Populismus und Post- Faktizität hat diese Prägung jedoch Dimensionen angenommen, die die Parameter dieses Sachverhalts deutlich verschieben. Ich werde in diesem Beitrag verschiedene Entwicklungen diskutieren, die einen öffentlichen Diskurs kenntlich machen, der als hochgradig prekär bezeichnet werden kann und der Änderungen sowie Gegenmaßnahmen benötigt. Anstatt bekannte und veraltete Politiken zu rekurrieren und einen potenziell konstruktiven Diskurs zu vernachlässigen, braucht es Ideen und Visionen einer evidenzbasierten, jedoch nicht technokratischen, Form eines Migrationsdiskurses und einer zukünftigen reflexiven Wissensproduktion.

description: The usage of the anthropic principle in modern cosmology is reviewed. It is argued that its recent use to explain the observedvalues of cosmological parameters as most probable values for an ensemble of universes, is not justified. However, the anthropic principle can be invoked to argue that a vast number of universes must exist, in which the cosmological parameters and constants of nature take on different values. This argument lends support to the hypothesis of eternal inflation and suggests that at least some of the parameters of the Standard Model cannot be quantitatively derived from an underlying theory.

description: We give a short review of our recent works on the first-order quantum phase transitions in frustrated spin chains with orthogonal-dimer structure. When the ratio of the competing antiferromagnetic exchange couplings is varied, a first-order transition occurs between the dimer phase and the plaquette phase, which is accompanied by the discontinuity in the spin excitation gap. We further show that strong frustration triggers the phase transitions in a magnetic field, which exhibit plateaus and jumps in the magnetization curve. The hole-doping effect is also addressed for the orthogonal-dimer chain with linked-tetrahedra structure. It is found that the competing antiferromagnetic interactions result in a first-order metal-insulator transition upon hole doping.

Comments on the nuclear symmetry energy

Subjects: subject: Nuclear Theory (nucl-th)

description: According to standard textbooks, the nuclear symmetry energy originates from the {\it kinetic} energy and the {\it interaction} itself. We argue that this view requires certain modifications. We ascribe the physical origin of the {\it kinetic} term to the discreteness of fermionic levels of, in principle arbitrary binary fermionic systems, and relate its mean value directly to the average level density. Physically it connects this part also to the isoscalar part of the interaction which, at least in self-bound systems like atomic nuclei, decides upon the spatial dimensions of the system. For the general case of binary fermionic systems possible external confining potentials as well as specific boundary conditions will contribute to this part. The reliability of this concept is tested using self-consistent Skyrme Hartree-Fock calculations.

description: This work aims to control the dynamics of certain non-Newtonian fluids in a bounded domain of $\mathbb{R}^d$, $d=2,3$ perturbed by a multiplicative Wiener noise, the control acts as a predictable distributed random force, and the goal is to achieve a predefined velocity profile under a minimal cost. Due to the strong nonlinearity of the stochastic state equations, strong solutions are available just locally in time, and the cost functional includes an appropriate stopping time. First, we show the existence of an optimal pair. Then,we show that the solution of the stochastic forward linearized equation coincides with the Gâteaux derivative of the control-to-state mapping, after establishing some stability results. Next, we analyse the backward stochastic adjoint equation; where the uniqueness of solution holds only when $d=2$. Finally, we establish a duality relation and deduce the necessary optimality conditions.
