“WAR IS PEACE, FREEDOM IS SLAVERY, AND IGNORANCE IS STRENGTH”. The slogan from George Orwell’s “1984” dystopia appears to capture the state of Russia’s 2014 official discourse quite accurately. This has not gone unnoticed by public and academic spectators in and outside Russia: while Bild magazine is counting Putin’s lies in his recent ARD interview, a Zeit article declares Russia itself to be a post-modern “lie”...
"European" interventions

Last week, this year’s ISA conference brought together over 5000 scholars and exhibitors from all over the world to discuss all things international, political, scholarly, hold meetings, get lunch together, and party at Mardi Gras (it was in New Orleans, after all!). Similar to last year, a lot of this discussing took also place on Twitter. Scholars-slash-tweeps rallied around the hashtag #isa2015 to talk to each other online about great (and not so great) panels, trends in IR scholarship, gender bias in academia, and (not surprisingly for an academic conference) coffee. Who was most active during ISA2015 on Twitter? What were the most hotly debated topics online? When did ISAlers tweet?
4 June 2013 marked the formal launch of the third generation of the Equator Principles (EP III) and the tenth anniversary of the EPs – enough reasons for evaluating the EPs initiative from an economic ethics and business ethics perspective. This chapter deals with the following questions: What has been achieved so far by the EPs? Which reform steps need to be adopted to further strengthen the EPs framework? Can the EPs be regarded as a role model in the field of sustainable finance and CSR? The first part explains the term EPs and introduces the keywords related to the EPs framework. The second part summarises the main characteristics of the newly-released third generation of the EPs. The third part critically evaluates EP III from an economic ethical and business ethics perspective. The chapter concludes with a summary of the main findings.
In many European countries poverty migration and its impact on the European continent are currently widely discussed topics. Many seem to forget about grave migration problems taking place in Asia, where in Hong Kong, for example, the working and living conditions for approximately 320,000 foreign domestic workers (mostly women) are often intolerable.
A rather disillusioned observation was recently made during a pan-Africa conference: Africa women consider new information and communication technologies as "futuristic" rather than a tool for development to be used today. If initiatives are not taken now to thwart this attitude, activities by women in Africa to promote sustainable development that also benefit them will take event longer. This will be especially true in regions on the continent where English is not the common language.
Detailed mass balance food web models were constructed to compare ecosystem characteristics for three Alaska regions: the eastern Bering Sea (EBS), the Gulf of Alaska (GOA), and the Aleutian Islands (AI). This paper documents the methods and data used to construct the models and compares ecosystem structure and indicators across models. The common modeling framework, including biomass pool and fishery definitions, resulted in comparable food webs for the three ecosystems which showed that they all have the same apex predator—the Pacific halibut longline fishery. However, despite the similar methods used to construct the models, the data from each system included in the analysis clearly define differences in food web structure which may be important considerations for fishery management in Alaska ecosystems. The results showed that the EBS ecosystem has a much larger benthic influence in its food web than either the GOA or the AI. Conversely, the AI ecosystem has the strongest pelagic influence in its food web relative to the other two systems. The GOA ecosystem appears balanced between benthic and pelagic pathways, but is notable in having a smaller fisheries catch relative to the other two systems, and a high biomass of fish predators above trophic level (TL) 4, arrowtooth flounder and halibut. The patterns visible in aggregated food webs were confirmed in additional more detailed analyses of biomass and consumption in each ecosystem, using both the single species and whole ecosystem indicators developed here.
The distribution of linguistic structures in the world is the joint product of universal principles, inheritance from ancestor languages, language contact, social structures, and random fluctuation. This paper proposes a method for evaluating the relative significance of each factor — and in particular, of universal principles — via regression modeling: statistical evidence for universal principles is found if the odds for families to have skewed responses (e.g. all or most members have postnominal relative clauses) as opposed to having an opposite response skewing or no skewing at all, is significantly higher for some condition (e.g. VO order) than for another condition, independently of other factors.
Nestling growth and development studies have been a topic of interest for a greater part of the last century (Sutton 1935, Walkinshaw 1948) and continue to be of interest today. This is not surprising since studies on nestling growth can provide a wealth of biological information that has larger implications for avian management and conservation. Despite this history of studying nestling development, basic information is still limited or absent for many species. Many questions remain unanswered, and contradictory conclusions are often found in the literature (Starck and Ricklefs 1998a). Therefore, much information on aging and development can still be gained from studying the development patterns of similar species and from comparative studies, across avian orders (Minea et al. 1982, Saunders and Hansen 1989, Carsson and Hörnfeldt 1993). Additionally, nestling growth studies can yield insight into the effects of different nesting strategies on productivity (O’Connor 1978), as well as the impacts of parental effort and environmental variables on fitness (Ross 1980, Ricklefs and Peters 1981, Magrath 1991). Since low reproductive success may play a significant role in the declines of many North American passerines (Sherry and Holmes 1992, Ballard et al. 2003), a better understanding of the factors that influence reproductive success is a vital component of avian conservation (Martin 1992). Data on nestling aging can be used to improve nest survival estimates (Dinsmore 2002, Nur et al. 2004), providing information that can be used to more precisely age nests (Pinkowski 1975, Podlesack and Blem 2002), (Jones and Geupel 2007). Indeed, the relatively short time period young spend developing in the nest is a critical part of a bird’s life cycle and a nestling’s developmental path can affect its survival to independence, its survival as an adult, and its future reproductive success.
In the last years, much effort went into the design of robust anaphor resolution algorithms. Many algorithms are based on antecedent filtering and preference strategies that are manually designed. Along a different line of research, corpus-based approaches have been investigated that employ machine-learning techniques for deriving strategies automatically. Since the knowledge-engineering effort for designing and optimizing the strategies is reduced, the latter approaches are considered particularly attractive. Since, however, the hand-coding of robust antecedent filtering strategies such as syntactic disjoint reference and agreement in person, number, and gender constitutes a once-for-all effort, the question arises whether at all they should be derived automatically. In this paper, it is investigated what might be gained by combining the best of two worlds: designing the universally valid antecedent filtering strategies manually, in a once-for-all fashion, and deriving the (potentially genre-specific) antecedent selection strategies automatically by applying machine-learning techniques. An anaphor resolution system ROSANA-ML, which follows this paradigm, is designed and implemented. Through a series of formal evaluations, it is shown that, while exhibiting additional advantages, ROSANAML reaches a performance level that compares with the performance of its manually designed ancestor ROSANA.
Hackethal and Schmidt (2003) criticize a large body of literature on the financing of corporate sectors in different countries that questions some of the distinctions conventionally drawn between financial systems. Their criticism is directed against the use of net flows of finance and they propose alternative measures based on gross flows which they claim re-establish conventional distinctions. This paper argues that their criticism is invalid and that their alternative measures are misleading. There are real issues raised by the use of aggregate data but they are not the ones discussed in Hackethal and Schmidt’s paper. JEL Classification: G30
A second Yalta

We study the following problem: given x element Rn either find a short integer relation m element Zn, so that =0 holds for the inner product <.,.>, or prove that no short integer relation exists for x. Hastad, Just Lagarias and Schnorr (1989) give a polynomial time algorithm for the problem. We present a stable variation of the HJLS--algorithm that preserves lower bounds on lambda(x) for infinitesimal changes of x. Given x \in {\RR}^n and \alpha \in \NN this algorithm finds a nearby point x' and a short integer relation m for x'. The nearby point x' is 'good' in the sense that no very short relation exists for points \bar{x} within half the x'--distance from x. On the other hand if x'=x then m is, up to a factor 2^{n/2}, a shortest integer relation for \mbox{x.} Our algorithm uses, for arbitrary real input x, at most \mbox{O(n^4(n+\log \alpha))} many arithmetical operations on real numbers. If x is rational the algorithm operates on integers having at most \mbox{O(n^5+n^3 (\log \alpha)^2 + \log (\|q x\|^2))} many bits where q is the common denominator for x.
A tale of two lost archives
(2009)
The long-run consumption risk model provides a theoretically appealing explanation for prominent asset pricing puzzles, but its intricate structure presents a challenge for econometric analysis. This paper proposes a two-step indirect inference approach that disentangles the estimation of the model's macro-economic dynamics and the investor's preference parameters. A Monte Carlo study explores the feasibility and efficiency of the estimation strategy. We apply the method to recent U.S.\data and provide a critical re-assessment of the long-run risk model's ability to reconcile the real economy and financial markets. This two-step indirect inference approach is potentially useful for the econometric analysis of other prominent consumption-based asset pricing models that are equally difficult to estimate.
This is the 26. article in our series Trouble on the Far-Right.
In Poland, the long lasting culture war1 over gender roles and religion has been easily framed by the far right into Samuel Huntington’s concept of the “clash of civilizations”. A well-known juxtaposition used in right-wing propaganda: ‘civilization of life’ vs. ‘civilization of death’ in reference to anti-abortion and pro-choice movements respectively is now used to refer to Christians and Muslims. The role of Polish women and the right to abortion remain in the center of the conflict of modernity.
In Europe, the far right heats up the moral panic caused by fear of terrorism, pointing to Muslims as a threat to ‘European’ liberties, especially women’s and LGBT rights. The assaults on women celebrating New Year’s Eve on the streets of Cologne, serve Pegida and many nationalist organizations in Europe as a proof of Arab’s attitude to ‘Western’ expressions of femininity. This argument in the anti-immigration discourse of the far right is well-grounded in nationalists’ ideal of a strong man defending ‘his’ woman. Although, the task might be understood literally, in the context of the assaults in Cologne, protecting wives, mothers, sisters and daughters of the nation has a broader symbolic meaning. Scholars interested in relationship between gender and nation, state that in nationalists discourse women symbolize the nation and are bearers of values.2 In islamophobic discourse female citizens of Europe signify Europeans’ equality and freedom...
To preserve the required beam quality in an e+/e- collider it is necessary to have a very precise beam position control at each accelerating cavity. An elegant method to avoid additional length and beam disturbance is the usage of signals from existing HOM-dampers. The magnitude of the displacement is derived from the amplitude of a dipole mode whereas the sign follows from the phase comparison of a dipole and a monopole HOM. To check the performance of the system, a measurement setup has been built with an antenna which can be moved with micrometer resolution to simulate the beam. Furthermore we have developed a signal processing to determine the absolute beam displacement. Measurements on the HOM-damper cell can be done in the frequency domain using a network analyser. Final measurements with the nonlinear time dependent signal processing circuit has to be done with very short electric pulses simulating electron bunches. Thus, we have designed a sub nanosecond pulse generator using a clipping line and the step recovery effect of a diode. The measurement can be done with a resolution of about 10 micrometers. Measurements and numerical calculations concerning the monitor design and the pulse generator are presented.
Guerillas win as long as they do not lose, and government forces lose as long as they do not win. In Afghanistan, this adage holds, once again, true. Western civilian and military leaders want us to believe that insurgents and criminals are running out of options. Indeed, after much initial stuttering, NATO has transformed into a veritable counter-insurgency machine, with the United States shouldering most of the burden. Casualties among the Taliban and other enemies of NATO are enormous. Enormous, too, is the coalition of NATO and Afghan troops, approaching half a million soldiers and militia-types.
AFK-EUPRA – 13 : feminist interventionism, postcolonial critique and non-western feminist approaches
(2017)
Europe’s reaction to the recent upheavals in North Africa clearly exposed one thing: The EU’s Common Foreign and Security Policy (CFSP), including its Security and Defence branch (CSDP), were steamrolled by a multitude of overtly national policies. The resulting cacophony of views made a mockery of the aspiration to present a united European position to external players. It also thwarts the claim of the EU being a more credible security actor in the wake of the Lisbon Treaty reforms. While commentators have moaned about a CFSP and CSDP ‘fatigue’ for quite some time now, the likelihood that what used to be the most dynamic EU policy field of the last decade will enter a period of prolonged hibernation never seemed as high...
We consider Schwarz maps for triangles whose angles are rather general rational multiples of pi. Under which conditions can they have algebraic values at algebraic arguments? The answer is based mainly on considerations of complex multiplication of certain Prym varieties in Jacobians of hypergeometric curves. The paper can serve as an introduction to transcendence techniques for hypergeometric functions, but contains also new results and examples.

An analysis of the UK's counter-terrorism strategy, CONTEST, and the challenges in its evaluation
(2016)
The UK’s Counter-Terrorism strategy, known as CONTEST, is recognized as one of the most successful soft-focus strategies in the world, with an intended emphasis on community support and what have become known as ‘Prevent’ (or counter-extremism) measures. In all, there are four limbs to CONTEST: PREVENT, PROTECT, PURSUE and PREPARE. While there is much crossover between these areas, for example policing activities take place in all four limbs, each one has a specific focus with its own intrinsic goals. This article intends to provide an overview of CONTEST, and to explore the challenges of evaluating counter-terrorism strategies in general. In doing so, I intend to show that while robust and independent evaluation of CONTEST has not been undertaken from a quantitative approach, some level of evaluation has taken place and can be taken into consideration when moving forward with future analysis of the strategy...
Beethoven's Ninth in Bailey Hall the other evening, April 20, ending in an instant standing ovation by a clearly enchanted audience, was an unforgettable experience. And, like all such truly extraordinary events that are marked not only by artistic merit, but draw their power from the circumstances surrounding their creation or performance, it recalled others and enhanced their significance. I was reminded of a stellar performance on Christmas Day of 1989, only weeks after the unexpected fall of the Berlin Wall on November 9, that haunting date in German history. Few people believed it would ever happen. But now, suddenly, reunification in justice and freedom, as the truncated old national anthem phrases it, was within reach.
Indo-European is a branch of Indo-Uralic which was radically transformed under the influence of a North Caucasian substratum when its speakers moved from the area north of the Caspian Sea to the area north of the Black Sea (cf. Kortlandt 2007b). As a result, Indo-European developed a minimal vowel system combined with a very large consonant inventory including glottalized stops, also grammatical gender and adjectival agreement, an ergative construction which was lost again but has left its traces in the grammatical system, especially in the nominal inflection, a construction with a dative subject which was partly preserved in the historical languages and is reflected in the verbal morphology and syntax, where it gave rise to new categories, and a heterogeneous lexicon. The Indo-Uralic elements of Indo-European include pronouns, case endings, verbal endings, participles and derivational suffixes. In the following I shall give an overview of the grammar of Proto-Indo-European as it may have been spoken around 4000 BC in the eastern Ukraine, shortly after the ancestors of the Anatolians left for the Balkans (for more recent developments I refer to Beekes 1995).
An analyst who works in Germany is more likely to publish a high (low) price target regarding a DAX30 stock if other Germany based analysts are also optimistic (pessimistic) about the same stock. This finding is not biased by the fact that DAX30 companies are headquartered in Germany. In times of bull markets, price targets of analysts who regularly exchange their opinion are higher correlated compared to other analysts. This effect vanishes in a bearish market environment. This suggests that communication among analysts indeed plays an important role. However, analysts’ incentives induce them not to deviate too much from the overall average during an economic downturn.
Report-no: UFTP-492/1999 Journal-ref: Phys.Rev. C61 (2000) 024909 We investigate flow in semi-peripheral nuclear collisions at AGS and SPS energies within macroscopic as well as microscopic transport models. The hot and dense zone assumes the shape of an ellipsoid which is tilted by an angle Theta with respect to the beam axis. If matter is close to the softest point of the equation of state, this ellipsoid expands predominantly orthogonal to the direction given by Theta. This antiflow component is responsible for the previously predicted reduction of the directed transverse momentum around the softest point of the equation of state.
Following on the ADEA/APNET study on inter-African Book trade that was commissioned in 1999, ADEA tasked APNET to facilitate the production of national book industry updates in each country. The updates are aimed at encouraging commercial development of inter-African book trade and to make available to the public, total systematic and current situations on the book trade in each country.
Given a real vector alpha =(alpha1 ; : : : ; alpha d ) and a real number E > 0 a good Diophantine approximation to alpha is a number Q such that IIQ alpha mod Zk1 ", where k \Delta k1 denotes the 1-norm kxk1 := max 1id jx i j for x = (x1 ; : : : ; xd ).

I’m probably not alone in observing that there seems to be an increasing number of data articles being published in the field of conflict studies and IR. Together with some colleagues, I’m even preparing one myself at the moment! Is that perceived increase in data publication actually measurable? And does it indeed amount to “drowning”?
We outline a procedure for consistent estimation of marginal and joint default risk in the euro area financial system. We interpret the latter risk as the intrinsic financial system fragility and derive several systemic fragility indicators for euro area banks and sovereigns, based on CDS prices. Our analysis documents that although the fragility of the euro area banking system had started to deteriorate before Lehman Brothers' file for bankruptcy, investors did not expect the crisis to affect euro area sovereigns' solvency until September 2008. Since then, and especially after November 2009, joint sovereign default risk has outpaced the rise of systemic risk within the banking system.
We study consumption-portfolio and asset pricing frameworks with recursive preferences and unspanned risk. We show that in both cases, portfolio choice and asset pricing, the value function of the investor/ representative agent can be characterized by a specific semilinear partial differential equation. To date, the solution to this equation has mostly been approximated by Campbell-Shiller techniques, without addressing general issues of existence and uniqueness. We develop a novel approach that rigorously constructs the solution by a fixed point argument. We prove that under regularity conditions a solution exists and establish a fast and accurate numerical method to solve consumption-portfolio and asset pricing problems with recursive preferences and unspanned risk. Our setting is not restricted to affine asset price dynamics. Numerical examples illustrate our approach.
As a sign of ambivalence in the regulatory definition of capital adequacy for credit risk and the quest for more efficient refinancing sources collateral loan obligations (CLOs) have become a prominent securitisation mechanism. This paper presents a loss-based asset pricing model for the valuation of constituent tranches within a CLO-style security design. The model specifically examines how tranche subordination translates securitised credit risk into investment risk of issued tranches as beneficial interests on a designated loan pool typically underlying a CLO transaction. We obtain a tranchespecific term structure from an intensity-based simulation of defaults under both robust statistical analysis and extreme value theory (EVT). Loss sharing between issuers and investors according to a simplified subordination mechanism allows issuers to decompose securitised credit risk exposures into a collection of default sensitive debt securities with divergent risk profiles and expected investor returns. Our estimation results suggest a dichotomous effect of loss cascading, with the default term structure of the most junior tranche of CLO transactions (“first loss position”) being distinctly different from that of the remaining, more senior “investor tranches”. The first loss position carries large expected loss (with high investor return) and low leverage, whereas all other tranches mainly suffer from loss volatility (unexpected loss). These findings might explain why issuers retain the most junior tranche as credit enhancement to attenuate asymmetric information between issuers and investors. At the same time, the issuer discretion in the configuration of loss subordination within particular security design might give rise to implicit investment risk in senior tranches in the event of systemic shocks.

Asset securitisation as a risk management and funding tool : what does it hold in store for SMES?
(2005)
The following chapter critically surveys the attendant benefits and drawbacks of asset securitisation on both financial institutions and firms. It also elicits salient lessons to be learned about the securitisation of SME-related obligations from a cursory review of SME securitisation in Germany as a foray of asset securitisation in a bank-centred financial system paired with a strong presence of SMEs in industrial production. JEL Classification: D81, G15, M20
Authoritarian regimes and religious institutions in the Muslim majority world see eye-to-eye on the topic of atheism. United by their fear of losing control over their populations and their desire for conformity, consecutive governments have pushed for unfair restrictions on their subjects’ beliefs since their inception. But even in society, non-belief remains a taboo. Should atheists in Muslim majority world become more vocal?
Regional actors like the European Union (EU) and the African Union (AU) are increasingly seeking to conceptualize their transitional justice engagements through policy frameworks and carve out spaces for themselves in transitional justice processes. While the EU adopted its Policy Framework on Support to Transitional Justice in November 2015, the AU is still in the process of developing its African Transitional Justice Framework. It is the starting assumption of this paper that the policy discourses inevitably have an effect on the understanding, scope and institutionalization of transitional justice that these two regional bodies will support – the EU mostly as a development strategy outside and the AU within its borders...
The basic problem of primary audio and video research materials is clearly shown by the survey: A great and important part of the entire heritage is still outside archival custody in the narrower sense, scattered over many institutions in fairy small collections, and even in private hands. reservation following generally accepted standards can only be carried out effectively if collections represent critical mass. Specialised audiovisual archives will solve their problems, as they will sooner or later succeed in getting appropriate funding to achieve their aims. A very encouraging example is the case of the Netherlands. The larger audiovisual research archives will also manage, more or less autonomously, the transfer of contents in time. For a considerable part of the research collections, however, the concept of cooperative models and competence centres is the only viable model to successfullly safeguard their holdings. Their organisation and funding is a considerable challenge for the scientific community. TAPE has significantly raised awareness of the fact that, unless action is swiftly taken, the loss of audiovisual materials is inevitable. TAPE’s international and regional workshops were generally overbooked. While TAPE was already underway, several other projects for the promotion of archives have received grants from organisations other than the European Commission, inter alia support for the St. Petersburg Phonogram Archive, and the Folklore Archive in Tirana, obviously as a result of a better understanding of the need for audiovisual preservation. When the TAPE project started its partners assumed that cooperative projects would fail because of the notorious distrust of researchers, specifically in the post-communist countries. One of the most encouraging surprises was to learn that, at least in the most recent survey, it became apparent that this social obstacle is fading out. TAPE may have contributed to this important development.
In this paper, I examine the potential of mobile alerting services empowering investors to react quickly to critical market events. Therefore, an analysis of short-term (intraday) price effects is performed. I find abnormal returns to company announcements which are completed within a timeframe of minutes. To make use of these findings, these price effects are predicted using pre-defined external metrics and different estimation methodologies. Compared to previous research, the results provide support that artificial neural networks and multiple linear regression are good estimation models for forecasting price effects also on an intraday basis. As most of the price effect magnitude and effect delay can be estimated correctly, it is demonstrated how a suitable mobile alerting service combining a low level of user-intrusiveness and timely information supply can be designed.
During the last decade, there has been a significant bias towards bond financing on emerging markets, with private investors relying on a bail-out of bonds by the international community. The bias has been a main cause for recent excessive fragility of international capital markets. The paper shows how collective action clauses in bonds contracts help to involve the private sector in risk sharing. It argues that such clauses, as a market based instrument, will raise spreads for emerging market debt and so help to correct a market failure towards excessive bond finance. Recent pressure by the IMF to involve the private sector is facing a conflict between the principle to honour existing contracts and the principle of equal treatment of bondholders.
There is every reason to welcome the revised edition (2009) of Thomas Olander’s dissertation (2006), which I have criticized elsewhere (2006). The book is very well written and the author has a broad command of the scholarly literature. I have not found any mistakes in Olander’s rendering of other people’s views. This makes the book especially useful as an introduction to the subject. It must be hoped that the easy access to a complex set of problems which this book offers will have a stimulating effect on the study of Balto-Slavic accentology.
Euro area data show a positive connection between sovereign and bank risk, which increases with banks’ and sovereign long run fragility. We build a macro model with banks subject to moral hazard and liquidity risk (sudden deposit withdrawals): banks invest in risky government bonds as a form of capital buffer against liquidity risk. The model can replicate the positive connection between sovereign and bank risk observed in the data. Central bank liquidity policy, through full allotment policy, is successful in stabilizing the spiraling feedback loops between bank and sovereign risk.
This article generalizes Schwinger’s mechanism for particles production in the arbitrary finite field volume. McLerran-Venugopolan(MV) model and iterative solution of DGLAP equation in the double leading log approximation for small x gluon distribution function were used to derive the new formula for initial chromofield energy density. This initial chromofield energy is distributed among color neutral clusters or strings of different length. This strings are stretched by receding nucleus. From the proposed mechanism of string fragmentation or color field decay based on exact solution of Dirac equation in the different finite volume, the new formulae for esimated baryon kinetic energy loss and rapidity spectrum of produced partons were derived.
The paper analyzes the mutual influence of the capital structure and the investment decision of a bank, as well as the incentive effects of the bank executives compensation schemes on these decisions. In case the government implicitly or explicitly insures deposits and/or the banks debt, banks are incentivized to invest in risky assets and to have a high leverage. Capital regulation could potentially solve this excessive risk taking problem. However, this is only possible if the regulator can observe and properly measure the investment risks of the bank, which was called into question during the 2008-09 financial crisis. Hence, we propose a regulatory approach that is also able to implement the first best risk taking levels by the bank, but does not require the regulator to know the investment risk of the bank. The regulatory approach involves the implementation of capital requirements, which are made contingent on the management compensation.
In hindsight, the debate about presupposition following Frege’s discovery that the referential function of names and definite descriptions depended on the fulfillment of an existence and a uniqueness condition was curiously limited for a very long time. On the one hand, it was only in the 1960s that linguists began to take an interest and showed that presupposition was an allpervasive phenomenon far beyond this philosophers’ pet definite descriptions. And on the other hand, and this is our real concern, it is now only too obvious that the uniqueness condition is too restrictive to be applicable to the general case. An utterance of “The cat is on the mat” should not imply that there is only one cat and one mat in the whole world. The obvious move is to limit the uniqueness condition to some notion of utterance context.
Large-scale digitisation has brought cultural heritage objects and materials from the remotest places of the world to our computer screens. At first sight, this innovation seems to make cultural heritage accessible to everyone like never before. However, technological advances have not eliminated social inequalities between powerful and marginalized communities and ethical issues in communicating cultural heritage. These issues became much more vivid and obvious when the spread of cultural heritage reached the global scale.
Part II of our series on ISIS : Blogforum "Kalifat des Terrors: Interdisziplinäre Perspektiven auf den Islamischen Staat"
On Thursday January 15, only a week after the bloodyattacks in Paris by the Kouachi brothers and AmedyCoulibali, Belgium was on high alert. In a raid carriedout by police and security forces in the small villageof Verviers, two alleged terrorists were shot dead, a third suspect wasarrested. The action was part of a larger operation carried out throughout thecountry to prevent imminent attacks by a group of Islamists, some of whomwere directly tied to the war in Syria and Iraq. In the days that followed itbecame clear that the prevented attacks probably were aimed at a highranking police official. The terror threat level was subsequently raised tolevel three, indicating that the threat of attacks was imminent. What makesBelgium such a hub for Jihadis?..
On 22 May 2017, the suicide bomber Salman Abedi killed 22 people and injured many more after an Ariana Grande concert in the Manchester Arena. On 9 September 2017, the Manchester Arena was reopened with a benefit show labelled as a “We Are Manchester” concert. The concert’s aim was to raise money for a place of memorial for the victims of the attack. “We Are Manchester” is only one of the many peaceful responses to the attacks: In contrast to the heated debates on increasing security, they reveal different ways of standing together for a liberal and diverse society against the fear caused by terrorism...
The text reframes the current debate about refugees in Germany by contrasting Germany’s recent history of racist violence and limitations of asylum laws with the resistance and agency of refugee movements across Germany. Both provide an important lens to re-examine the simultaneous heralding of „welcome culture“, a sharp rise in arson attacks on asylum centres and the current legislative roll-back of refugee rights in Germany.
The current study was part of a series of environment related studies of the Jabal Akhdar sponsored by the Sultan Qaboos University, Al Khoud, Sultanate of Oman. The present study aimed to establish the range, habitat, status and population of breeding species in the area, review the historical perspective and list migrant and visitor species noted during the survey.
Black box cryptanalysis applies to hash algorithms consisting of many small boxes, connected by a known graph structure, so that the boxes can be evaluated forward and backwards by given oracles. We study attacks that work for any choice of the black boxes, i.e. we scrutinize the given graph structure. For example we analyze the graph of the fast Fourier transform (FFT). We present optimal black box inversions of FFT-compression functions and black box constructions of collisions. This determines the minimal depth of FFT-compression networks for collision-resistant hashing. We propose the concept of multipermutation, which is a pair of orthogonal latin squares, as a new cryptographic primitive that generalizes the boxes of the FFT. Our examples of multipermutations are based on the operations circular rotation, bitwise xor, addition and multiplication.
This is the 20. article in our series Trouble on the-Far-Right.
Just a few days ago during a parliamentary session, a Kurdish deputy was violently attacked and injured by members of the governing Justice and Development Party (AKP). As if to support Charles Tilly’s statement that ‘political violence occurs when actors have few opportunities, yet enough resources to mobilize for violence’1, many groups in Turkey are currently involved in a battle against Kurdish, Alevi or left Turkish citizens. The Turkish President Recep Tayyip Erdoğan in a political stalemate, uses military and police, but also the Nationalist Movement Party’s (MHP) youth organization Grey Wolves as well as Islamist militias like Esedullah Timleri (Arabic for: Lions of Allah) have increasingly resorted to violence as tool of action.
Political violence has been a central characteristic of the Turkish far right, which largely resembles street-based mobilization in Western Europe. Despite the common ultra-nationalist ideology, the Gülen Movement (GM) stands out. AKP’s former “soft-power instrument” now appears to be the only reasonable and non-violent player among all of these self-named animal groups. Since the power struggle escalated between Erdoğan and Fethullah Gülen in 2013, the GM has been seen as a victim of Erdoğan’s repressive measures, instead of making itself conspicuous by using violence. How can we explain this exception?
We generalize the concept of block reduction for lattice bases from l2-norm to arbitrary norms. This extends the results of Schnorr. We give algorithms for block reduction and apply the resulting enumeration concept to solve subset sum problems. The deterministic algorithm solves all subset sum problems. For up to 66 weights it needs in average less then two hours on a HP 715/50 under HP-UX 9.05.
This year’s conference of the AFK (German Association for Peace and Conflict Studies) and the European Peace Research Association (EuPRA) is on "Peace and Conflict Studies from the Margins to the Centre; Rethinking Europe in an Unequal World" (16 – 18 March 2017 in Schwerte (nearby Dortmund), Germany).
The virtual realm of the internet is often seen as an egalitarian world where differences such as those between young and established researchers do not seem so significant. While we do not fully agree with this thesis, we want to use this blog to make a model attempt at providing a platform in which those participating in the conference and others can enter discussion with young students, established researchers, and peace activists.
To make this possible, we started a project in cooperation with the Bretterblog – a young team of researchers who established this blog some years ago. Here we will discuss the topics of the conference and will inform a broader audience about the newest results in peace and conflict research from different countries.
Political rationality as a theory is important in its own right. Government leaders must calculate political costs such as the resources needed to generate support for a policy, the implications of a policy decision for re-election, and the possibility of provoking hostility for decisions not well received. Bounded rationality approach has yielded an enhanced understanding of how government organizations may produce unexpected or even unpredicted policy or program results. With public organizations not operating under full rationality conditions, administrators aspiring toward rationality may nonetheless find their goals undermined by a variety of forces, such as informational uncertainties and non-rational elements of organisational decision-making...

Brecht - Galileo
(2010)
This is the age of doubt, says Brecht's Galileo, the 17th century scientist. "It ain't necessarily so," says Gershwin's Sportin' Life of the 1930ies. "De t'ings dat yo li'ble / to read in de Bible / it ain't necessarily so. / Now I takes dat gospel / whenever it's pos'ble / but wid a grain of salt."

Trouble’s brewing for the European Union – also in Finland, where the next country-wide elections will see several new, EU-hostile nationalist groups attempt to establish themselves on the political map. At the same time, Finnish Fascism is seeking to entrench and normalize itself into a respectable part of the political framework.
With disaffection growing, the time appears to be ripe. As Heikki Hiilamo, professor of social policy in Helsinki University notes, Finland has been particularly hard hit by the most recent economic downturn. The middle and lower classes are seeing their expectations fade into uncertainty, as globalization is bringing new and intangible threats in the form of vanishing jobs. Finland is heading towards increasing social inequality, with the reality of the educated and the employed drifting further apart from “globalization’s losers”. With no self-evident owner in sight, the accumulating political capital is attracting radical nationalist utilizers...
In his early years, C. C. Uhlenbeck was particularly interested in the problem of the Indo-European homeland (1895, 1897). He rejected Herman Hirt’s theory (1892) that the words for ‘birch’, ‘willow’, ‘spruce’, ‘oak’, ‘beech’ and ‘eel’ point to Lithuania and its immediate surroundings and returned to Otto Schrader’s view (1883, 1890) that the original homeland must rather be sought in southern Russia and may have included some of the later Germanic and Iranian territories. It is clear that the Mediterranean region and the area around the North Sea can safely be excluded because the arrival of the Indo-Europeans was comparatively recent here, as it was in Iran and the Indian subcontinent. It is difficult to be more specific within the limits of central and eastern Europe and central Asia. Uhlenbeck was impressed by the lexical correspondences between Indo-European and Semitic which had been adduced in favor of an eastern homeland but pointed out that borrowings from Semitic may have reached the Indo-Europeans through an intermediary. He agrees that the Indo-European words for trees and animals point to a moderate climate but questions the possibility of a more specific localization as well as the concept of homeland itself.
Bency Eichorn learns in kollel and, on the side, has been researching about various segulos. For his wedding he authored a book, Simchas Zion, discussing the segulah of keeping the afikomom from year-to-year. The post below is a small part of a much larger project on this segulah and has been adapted for the blog.
With the current conflict in Gaza going full tilt, the usual questions have popped up: Who is to blame, what is everyone’s motivation and strategy, how to stop the bloodshed, how to end the conflict. And as usual, the two-state solution, i.e. two separate, sovereign states within the borders of the 1949 armistice agreement, keeps popping up as a purported solution. This is especially prominent in the statements of politicians in countries not directly involved in the conflict. Countries that at least claim to want to help end the conflict, be it through mediation or other diplomatic measures. But for those countries, the two-state solution has become an idea to hide behind. It does not help solve the conflict, neither in the short- nor mid-term. Clinging to the idea merely prolongs the status quo. However, it does allow the rest of the world to avoid facing the facts, which would force them to reevaluate their position on who to support and actually do something about the conflict as it currently is. But it’s high time we face the music and admit it: The two-state solution is no longer a viable option when it comes to mediating this conflict...
This is the 22. article in our series Trouble on the Far-Right.
Changing political and economic situations generate new types of political protagonists – the far right is no exception here. Whether its structures and organizational forms endure, whether they diffuse (trans)nationally, whether their models prove successful, depends on various factors. A model that is currently about to serve as a flagship for the far right in Europe is the neo-fascist movement / party CasaPound. So why is this organizational model within the far right in Italy and Europe so successful?
My contribution is intended to shed light on the hybridity of CasaPound and the resulting force for the renewal of fascism. To carry out my argument, I will first describe the evolution of CasaPound from a movement to a party. Then I will discuss strategies and practices in terms of organizational and ideological hybridization, to finally outline the European dimension of the self-proclaimed „fascists of the third millennium“...
The idea of appointing a non-national as Central Bank Governor remains surprisingly controversial. Nevertheless, given the skills required by the Governor in order to manage what no doubt are increasingly complex institutions, considering non-nationals makes good sense for at least two reasons. First, increasing the pool of candidates to include those with broader skills and backgrounds makes it easier to find a suitable person for the job. Second, non-nationals are less likely to be beholden to domestic pressure groups and could help better insulate the central bank from political pressures.
Central wage bargaining and local wage flexibility : evidence from the entire wage distribution
(1998)
We argue that in labor markets with central wage bargaining wage flexibility varies systematically across the wage distribution: local wage flexibility is more relevant for the upper part of the wage distribution, and flexibility of wages negotiated under central wage bargaining affects the lower part of the wage distribution. Using a random sample of German social-security accounts, we estimate wage flexibility across the wage distribution by means of quantile regressions. The results support our hypothesis, as employees with low wages have significantly lower local wage flexibility than high wage employees. This effect is particularly relevant for the lower educational groups. On the other hand, employees with low wages tend to have a higher wage flexibility with respect to national unemployment.
We analyze the market reaction to the sentiment of the CEO speech at the Annual General Meeting (AGM). As the AGM is typically preceded by several information disclosures, the CEO speech may be expected to contribute only marginally to investors’ decision making. Surprisingly, however, we observe from the transcripts of 338 CEO speeches of German corporates between 2008 and 2016 that their sentiment is significantly related to abnormal stock returns and trading volume around the AGM. By adapting a finance-specific German dictionary based on Loughran and McDonald (2011), we find a negative association of the post-AGM returns with the speeches’ negativity and a positive association with the speeches’ relative positivity (i.e. positivity relative to negativity). Relative positivity moreover corresponds with a lower trading volume around the AGM. Investors hence seem to perceive the sentiment of CEO speeches at AGMs as a valuable indicator of future firm performance. Our results are robust against different weighting schemes and our dictionary appears to be better suited to grasp the sentiment of German business documents compared to general dictionaries.
Several classes of chemicals that are known or suspected contaminants were found in bed sediment in Rock Creek, including polyaromatic hydrocarbons (PAHs), phthalate esters, organochlorine pesticides, dioxins and furans, trace metals and metalloids (mercury, arsenic, cadmium, chromium, cobalt, copper, lead, nickel, silver, and zinc), and polychlorinated biphenyls (total PCBs and selected aroclors). Concentrations of many of these chemicals consistently exceeded thresholdor chronic-effects guidelines for the protection of aquatic life and often exceeded probable effects levels (PELs). Exceedance of PELs was dependent on the amount of total organic carbon in the sediments. Concurrent with the collection of sediment-quality data, white sucker (Catostomus commersoni) were evaluated for gross-external and internal-organ anomalies, whole-body burdens of chemical contaminants, and gut contents to determine prey. The histopathology of internal tissues of white sucker was compared to contaminant levels in fish tissue and bed sediment. Gut contents were examined to determine preferential prey and thus potential pathways for the bioaccumulation of chemicals from bed sediments. Male and female fish were tested separately. Lesions and other necroses were observed in all fish collected during both years of sample collection, indicating that fish in Rock Creek have experienced some form of environmental stress. No direct cause and effect was determined for chemical exposure and compromised fish health, but a substantial weight of evidence indicates that white sucker, which are bottom-eeding fish and low-order consumers in Rock Creek, are experiencing some reduction in vitality, possibly due to immunosuppression. Abnormalities observed in gonads of both sexes of white sucker and observations of abnormal behavior during spawning indicated some interruption in reproductive success.
