Editorial: Natur, Gesellschaft, Materialität: aktuelle Herausforderungen der
Politischen Ökologie
Authors: Becker Sören , Otto Antje
Published: October 2016

Abstract. This editorial introduces different theoretical strands in political ecology both in English and German speaking contexts. Comparing Marxist with more relational and "new materialist" approaches, it is argued that the various theoretical approaches chosen induce different ways of how the relationship between society and nature, between material and culture is conceptualized. The dialectical perspective derived from Marxism is thereby contrasted with the more emergent, and relativist understandings of actor network theory and assemblage thinking. Besides, the six single contributions in this Special Issue are introduced and five areas for further research are laid out: (1) the multiplicity of materiality, (2) the opposition between dialectic and relativist thinking, (3) the tension between elements and entire socio-material configurations, (4) materiality in the production of space and (5) issues of materiality and power.
Immer Ärger mit der Materialität? – Politische Ökologie und das Dispositiv der Dürre im Nordosten Brasiliens
Authors: Schmitt Tobias
Published: October 2016

Abstract. While the role of materiality was understudied in most social sciences, there was a sensibility for these issues in political ecology. The different approaches of political ecology focused on the political character of ecology and the ecological (and thus material) character of politics. But a conceptual framework that captures the different dimensions of the societal nature relations was seldom explicitly elaborated. Following the considerations of Michel Foucault, this article explores whether dispositive analysis as a concept and as a method offers a way to integrate both social and material conditions into studies of political ecology. By examining water infrastructure and the dispositive of drought in Northeastern Brazil, this paper displays how dispositive analysis is a means to identify different elements, their autonomies as well as their interconnectedness. Focusing on the entanglements of discourses, institutionalizations, subjectivity, practices and materiality allows capturing the materiality of discourses and the discursivity of material orders.
Politische Ökologie des Postsozialismus
Authors: Schmidt Matthias
Published: October 2016

Abstract. The consequences and effects of the socialist experiment are still felt today, a quarter century after the system change in Eastern Europe and the Soviet Union. The political, economic and social transformation processes which occurred in this period have only partially led to a convergence with the West. The former socialist societies show, to this day, striking differences and specific paths, which is why "postsocialism" as an explanatory category is still of relevance. Although political ecology was established decades ago, its research activities touching various fields and resulting in numerous studies conducted in rural and urban contexts around the world, there are hardly any political-ecological studies that deal with the post-socialist reality of Eurasia. A central field of political ecology stems from questions about the relationships between political and socio-economic transformation processes, on the one hand, and poverty, vulnerability and environmental change, on the other. Such problems occur in a particularly striking manner in the former "Second World" countries. Here, the spatial and temporal multiscalar approach of political ecology appears well suited to analyse the transformations of human-environment relationships. Political-ecological studies in the post-socialist sphere must take into account some special features, such as the legacy of socialist modernization, the disastrous environmental damages of the planned economy or the reconfiguration of institutions. This article discusses the conceptual particularities and challenges for a political ecology of post-socialism.
Coupling urban drainage–wastewater systems and electric smart grids during dry periods: a gain/loss framework using the relative economic value with ensemble flow forecasts to predict the switch
between management objectives

Published: October 2016

Abstract. Precipitation is the major perturbation to the flow in urban drainage and wastewater systems. Flow forecast, generated by coupling rainfall predictions with a hydrologic runoff model, can potentially be used to optimise the operation of Integrated Urban Drainage–Wastewater Systems (IUDWS) during both wet and dry weather periods. Numerical Weather Prediction (NWP) models have significantly improved in recent years; increasing their spatial and temporal resolution. Finer resolution NWP are suitable for urban catchment scale applications, providing longer lead time than radar extrapolation. However, forecasts are inevitably uncertain and fine resolution is especially challenging for NWP. This uncertainty is commonly addressed in meteorology with Ensemble Prediction Systems (EPS). Handling uncertainty is challenging for decision makers and hence tools are necessary to provide insight on ensemble forecast usage and to support the rationality of decisions (i.e. forecasts are uncertain therefore errors will be made, decision makers need tools to justify their choices, demonstrating that these choices are beneficial in the long run). This study presents an economic framework to support the decision making process by providing information on when acting on the forecast is beneficial and how to handle the EPS. The Relative Economic Value (REV) approach associates economic values to the potential outcomes and determines the preferential use of the EPS forecast. The envelope curve of the REV diagram combines the results from each probability forecast to provide the highest relative economic value for a given gain-loss ratio. This approach is traditionally used at larger scales to assess mitigation measures for adverse events (i.e. the actions are taken when events are forecasted). The specificity of this study is to optimise the energy consumption in IUDWS during low flow periods by exploiting the electrical smart grid market (i.e. the actions are taken when no events are forecasted). Furthermore, the results demonstrate the benefit of NWP neighbourhood post-processing methods to enhance the forecast skill and increase the range of beneficial use.
Characteristics and causes of Deep Western Boundary Current transport variability

Published: October 2016

Abstract. The Deep Western Boundary Current (DWBC) at 34.5° S in the South Atlantic carries a significant fraction of the cold deep limb of the Meridional Overturning Circulation (MOC), and therefore its variability affects both the meridional heat transport and the regional and global climate. Nearly six years of observations from a line of pressure-equipped inverted echo sounders (PIES) have yielded an unprecedented data set for studying the characteristics of the time-varying DWBC volume transport at 34.5° S. Furthermore, the horizontal resolution of the observing array was greatly improved in December 2012 with the addition of two current-and-pressure-equipped inverted echo sounders (CPIES) at the midpoints of three of the existing sites. Regular hydrographic sections along the PIES/CPIES line confirm the presence of recently-ventilated North Atlantic Deep Water carried by the DWBC. The time-mean absolute geostrophic transport integrated within the DWBC layer, defined between 800–4800 dbar, and within longitude bounds of 51.5° W to 44.5° W is −15 Sv (1 Sv = 106 m3 s−1; negative indicates southward flow). The observed peak-to-peak range in volume transport using these integration limits is from −89 Sv to +50 Sv, and the temporal standard deviation is 23 Sv. Testing different vertical integration limits based on time-mean water-mass property levels yields small changes to these values, but no significant alteration to the character of the transport time series. The time-mean southward DWBC flow at this latitude is confined west of 49.5° W, with recirculations dominating the flow further offshore. As with other latitudes where the DWBC has been observed for multiple years, the time variability greatly exceeds the time-mean, suggesting the presence of strong coherent vortices and/or Rossby Wave-like signals propagating to the boundary from the interior.
East African wetland-catchment data base for sustainable wetland management
Authors: Leemhuis Constanze , Amler Esther , Diekkrüger Bernd , Gabiri Geofrey , Näschen Kristian
Published: October 2016

Abstract. Wetlands cover an area of approx. 18 Mio ha in the East African countries of Kenya, Rwanda, Uganda and Tanzania, with still a relative small share being used for food production. Current upland agricultural use intensification in these countries due to demographic growth, climate change and globalization effects are leading to an over-exploitation of the resource base, followed by an intensification of agricultural wetland use. We aim on translating, transferring and upscaling knowledge on experimental test-site wetland properties, small-scale hydrological processes, and water related ecosystem services under different types of management from local to national scale. This information gained at the experimental wetland/catchment scale will be embedded as reference data within an East African wetland-catchment data base including catchment physical properties and a regional wetland inventory serving as a base for policy advice and the development of sustainable wetland management strategies.
Investigation of hydrological variability in the Korean Peninsula with the
ENSO teleconnections
Authors: Yoon Sunkwon , Lee Taesam
Published: October 2016

Abstract. This study analyzes nonlinear behavior links with atmospheric teleconnections between hydrologic variables and climate indices using statistical models during warm season (June to September) over the Korean Peninsula (KP). The ocean-related major climate factor, which is the El Niño-Southern Oscillation (ENSO) was used to analyze the atmospheric teleconnections by principal component analysis (PCA) and a singular spectrum analysis (SSA). The nonlinear lag time correlations between climate indices and hydrologic variables are calculated by Mutual Information (MI) technique. The nonlinear correlation coefficients (CCs) by MI were higher than linear CCs, and ENSO shows a few months of lag time correlation. The warm season hydrologic variables in KP shows a significant increasing tendency during the warm pool (WP), and the cold tongue (CT) El Niño decaying years shows a significant decreasing tendency, while the La Niña year shows slightly above normal conditions, respectively. A better understanding of the relationship between climate indices and streamflow, and their local impacts can help to prepare for the river discharge management by water managers and scientists. Furthermore, these results provide useful data for policy makers and end-users to support long-range water resources prediction and water-related policy.
Decadal oscillations of the aquatic chemistry of river waters in Latvia
Authors: Porshnov Dmitry , Klavins Maris
Published: October 2016

Abstract. Water quality changes of surface waters can be used to assess human impact intensity, but of importance is to consider also impacts of climate change/variability and naturally occurring changes of environmental quality. In Latvia, during the recent decades a major reduction of anthropogenic pressure has happened due to restructuring of economy and industrial production, resulting in major decrease of loading of many groups of pollutants. However, trends and driving factors for other groups of substances have not been much studied. Long term (1980–2012) results of hydrochemical monitoring, performed in rivers of Latvia, are analysed during this study in connection with long-term sets of hydrological and heliophysical data, using standard statistical approaches. Our results indicate that variation of some hydrochemical values, for example COD and total Fe, show clearly visible decadal oscillated character, while variation of some other values, for example phosphate P and total P, show some individual characteristics of decadal oscillations. These results indicate the presence of a large scale, geochemical and geophysical significant process: multiannual pulse of catchment, driven by variation of solar irradiance through complex interactions between global atmospheric circulation, groundwater and surface waterbodies. The process described in our study is significant from a geochemical point of view and must be taken into account in prediction of water quality and quantity. Impacts of natural processes should be considered in the planning of environmental policy.
Crystal balls into the future: are global circulation and water balance models ready?
Authors: Fekete Balázs M. , Pisacane Giovanna , Wisser Dominik
Published: October 2016

Abstract. Variabilities and changes due to natural and anthropogenic causes in the water cycle always presented a challenge for water management planning. Practitioners traditionally coped with variabilities in the hydrological processes by assuming stationarity in the probability distributions and attempted to address non-stationarity by revising this probabilistic properties via continued hydro-climatological observations. Recently, this practice was questioned and more reliance on Global Circulation Models was put forward as an alternative for water management plannig. This paper takes a brief assessment of the state of Global Circulation Models (GCM) and their applications by presenting case studies over Global, European and African domains accompanied by literature examples. Our paper demonstrates core deficiencies in GCM based water resources assessments and articulates the need for improved Earth system monitoring that is essential not only for water managers, but to aid the improvements of GCMs in the future.

Abstract. The assessment of water balance components using global hydrological models is subject to climate forcing uncertainty as well as to an increasing intensity of human water use within the 20th century. The uncertainty of five state-of-the-art climate forcings and the resulting range of cell runoff that is simulated by the global hydrological model WaterGAP is presented. On the global land surface, about 62 % of precipitation evapotranspires, whereas 38 % discharges into oceans and inland sinks. During 1971–2000, evapotranspiration due to human water use amounted to almost 1 % of precipitation, while this anthropogenic water flow increased by a factor of approximately 5 between 1901 and 2010. Deviation of estimated global discharge from the ensemble mean due to climate forcing uncertainty is approximately 4 %. Precipitation uncertainty is the most important reason for the uncertainty of discharge and evapotranspiration, followed by shortwave downward radiation. At continental levels, deviations of water balance components due to uncertain climate forcing are higher, with the highest discharge deviations occurring for river discharge in Africa (−6 to 11 % from the ensemble mean). Uncertain climate forcings also affect the estimation of irrigation water use and thus the estimated human impact of river discharge. The uncertainty range of global irrigation water consumption amounts to approximately 50 % of the global sum of water consumption in the other water use sector.

Water resources assessment and prediction in China
Authors: Guangsheng Wang , Ning Dai , Jianqing Yang , Jinxing Wang
Published: October 2016

Abstract. Water resources assessment in China, can be classified into three groups: (i) comprehensive water resources assessment, (ii) annual water resources assessment, and (iii) industrial project water resources assessment. Comprehensive water resources assessment is the conventional assessment where the frequency distribution of water resources in basins or provincial regions are analyzed. For the annual water resources assessment, water resources of the last year in basins or provincial regions are usually assessed. For the industrial project water resources assessment, the water resources situation before the construction of industrial project has to be assessed. To address the climate and environmental changes, hydrological and statistical models are widely applied for studies on assessing water resources changes. For the water resources prediction in China usually the monthly runoff prediction is used. In most low flow seasons, the flow recession curve is commonly used as prediction method. In the humid regions, the rainfall-runoff ensemble prediction (ESP) has been widely applied for the monthly runoff prediction. The conditional probability method for the monthly runoff prediction was also applied to assess next month runoff probability under a fixed initial condition.
Bromine, iodine and sodium in surface snow along the 2013 Talos Dome – GV7 traverse (Northern Victoria Land, East Antarctica)
Authors: Maffezzoli Niccolò , Spolaor Andrea , Barbante Carlo , Bertò Michele , Frezzotti Massimo , Vallelonga Paul
Published: October 2016

Abstract. Halogen chemistry in the polar regions occurs through the release of sea salt rich aerosols from sea ice surfaces and organic compounds from algae colonies living within the sea ice environment. Measurements of halogen species in polar snow samples are limited to a few sites although they are shown to be closely related to sea ice extent. We examine here total bromine, iodine and sodium concentrations in a series of 2 m cores collected during a traverse from Talos Dome (72°48' S, 159°06' E) to GV7 (70°41' S, 158°51' E), analyzed by Inductively Coupled Plasma Sector Field Mass Spectrometry (ICP-SFMS) at a resolution of 5 cm. We find a distinct seasonality of the bromine enrichment signal in all cores, with maxima during the austral late spring. Iodine showed average concentrations of 0.04 ppb with little variability. No distinct seasonality was found for iodine and sodium. The transect revealed homogeneous fluxes for the three chemical species along the transect, due to competing effects of air masses originating from the Ross Sea and the Southern Ocean. The flux measurements are consistent with the uniform values of BrO and IO detected from satellite observations. Similar trends are found for annual bromine enrichment and 130–190° E First Year Sea Ice for the 2010–2013 period.
The Social Life of Gas Stations
Authors: Giovannoni Giulio
Published: October 2016

Literature on gas stations is attributable to a handful of approaches: a nostalgic/historical approach on the first vernacular manifestations of such roadside artifacts; an opposite bleak approach, stressing their features of "non-places"; the obvious branch of technological literature; and a few others. Almost never are gas stations considered as public spaces. However gas stations, as well as other curbside artifacts, abound of social life. This is particularly true in Italy, where thanks to the post-war tradition of Autogrill, gas stations are often much more than just a place to fill up. They provide coffee shops, restaurants, pastry shops, as well as newsstands, stores, food vendors, not to say of the inevitable Mac Drives. Al that accessible, easy to park, and in many instances open 24/7, in a country which shuts at 7.00 pm, or at best at 9.00 pm. Therefore gas stations end to be the crossroads of many social interactions, especially – but not only –of youth subcultures. For these reasons gas stations deserve being studied for what they are, avoiding both nostalgic and bleak approaches. The paper presents the first results of an ongoing research on the social life of gas stations in central Italy. It is structured in five main sections. Section one synthesizes the main positions on gas stations, from the pessimistic ones equating gas stations to nonplaces, to the more optimistic framing gas stations within street and car cultures. Section two frames the relevance of gas stations within the wider transformation produced on cities by the advent of car. Section three provides an historical framework in order to explain today’s social relevance of gas stations in Italy. Section four presents the research findings on the social life of such ‘architectures in motion’, confirming the importance of gas stations for public life. The conclusive section of the paper draws policy implications of such findings claiming the necessity of explicitly designing gas stations as places for public life.
Public Space Trends in Hong Kong. A view from the New Territories
Authors: Tieben Hendrik
Published: October 2016

Hong Kong’s vertical urban landscape, bustling street markets, and multi-layered urban spaces have attracted a range of scholars (Cuthbert and McKinnell, 1997; Smith, 2005; Frampton [et al.], 2010; Shelton [et al.], 2011). Therefore, this paper focuses on aspects of Hong Kong’s public spaces, which so far have caught less attention, but affect the majority of its residents today. The paper starts with the following observations: (1) More than half of Hong Kong’s population (52,2%) lives today in the New Territories, an area usually outside of international attention (Census 2011); (2) Here, most people live in public and private housing estates, constructed over the last 40 years; (3) Individual estates can reach a population size of entire European towns and their “public spaces” – if one can name them as such – follow strict rules and have their own spatial conditions; (4) The street patterns, which connect these estates with their surrounding are fundamentally different from those of the older urban areas on Hong Kong Island and the Kowloon Peninsula. Basically, in these new developments we don’t find the bustling street markets or the complex multi-layered spatial conditions anymore, which have caught most international attention (e.g. Frampton [et al.], 2010); and, (5) through urban renewal and redevelopment these new spatial conditions are introduced also to the older urban areas. As a response, there have been a growing number of initiatives by civil society groups to recapture the original role of streets as public spaces to offer more opportunities for economic and social activities, and re-enable expressions different cultural identities, life styles, and political views.
Learning, Thinking and Living Tokyo. Doing urban research in cultures radically different to that of our own
Authors: Radović Darko
Published: October 2016

In 2011, at Keio University, Tokyo, we launched Measuring the non-Measurable, with academic and practitioners involved in production of space in ten cities of Asia (Tokyo, Bangkok, Beijing, Hong Kong, Singapore), Australia (Melbourne) and Europe (Barcelona, Belgrade, Copenhagen, Florence).
The intention of Mn’M was never to question the importance of quantifiable dimensions of life. One of its critical aims was to argue for an equally respectful treatment of other dimensions of knowing, as neither the quantifiable not the non-quantifiable alone can fully cover the key dimensions of the synthetic quality which we seek to live. The cities are always in and of a particular place, in and of a particular time. That double contextualisation makes their realities enormously dynamic and complex. The complexity itself and the groundedness in concrete, unique situations are the key aspects of being urban.
Mapping the lived experiences of Bangkok’s soi
Authors: Boontharm Davisi
Published: October 2016

One of the most distinctive urban characteristics of Bangkok is its sois. Soi is an alley that branches out from the main thoroughfares. This terminology applies to both the artery system of streets and canals. Soi is considered as a sub-street or a tertiary type in the hierarchy of the streets of Bangkok, the spatial layout of which follows old agricultural patterns of the water based settlement. They produce the labyrinth-like spatial and social configurations initiated by various agreements and practices between the landowners and residents. The public investment in road infrastructure couldn’t cope with the speed of urbanisation in Bangkok. Apart from the main roads constructed by the public authorities, the soi where the majority of population in Bangkok lives is created by private initiative.
For this paper, I only present part of the bigger project, which is still on going. In this very initial state of my investigation, I focus only on one family; mine.
Time Series Chaos Detection and Assessment via Scale Dependent Lyapunov Exponent
Authors: Fenga Livio
Published: October 2016

Many dynamical systems in a wide range of disciplines -- such as engineering, economy and biology -- exhibit complex behaviors generated by   nonlinear components which might result in deterministic chaos. While in  lab--controlled setups its detection and level estimation  is in general a doable task, usually the same  does not hold for many   practical applications. This is because experimental conditions imply facts like low signal--to--noise ratios, small sample sizes and not--repeatability  of the experiment, so that the performances of the tools commonly employed for chaos detection can be seriously affected.  To tackle this problem, a combined approach based on wavelet and chaos theory is proposed. This is a procedure designed to provide the analyst with qualitative and quantitative information, hopefully conducive to a better understanding of the dynamical system the time series under investigation is generated from. The chaos detector considered is the well known Lyapunov Exponent. A real life application, using the Italian Electric Market price index, is employed to corroborate the validity of the proposed approach.
Determination of Support Vector Boundaries in Generalized Maximum Entropy for Multilevel Models
Authors: Depren Serpil Kilic , Depren Özer
Published: October 2016

Generalized Maximum Entropy (GME) approach is one of the alternative estimation methods for Regression Analysis. GME approach is superior to other classical approaches in terms of parameter estimation accuracy when some or none of the assumptions of classical approaches are violated. However, determining bounds of parameter support vectors is one of the open parts of this approach when researchers have no prior information about the parameters. If support vectors cannot be determined correctly, parameters estimations will not be obtained correctly. There are some theoretical studies about GME for different datasets in the literature, but there are fewer studies about how to determine parameter support vectors. To obtain robust parameter estimations in GME, we introduced a new iterative procedure for determining parameter support vectors bounds for multilevel dataset. In this study, the new iterative procedure was applied for multi-level random intercept model and the new procedure was tested both simulation study and the real life data. The Classical and the new procedures of GME estimations were compared to Generalized Least Square Estimations in terms of Root Mean Square Error (RMSE) statistics. As a result, the estimations of the new approach provided lower RMSE values than classical methods.

Published: October 2016

Introduction: Considering the high prevalence of anger problems in adolescence and the importance of emotion regulation in this age period, this study aims to assess the effectiveness of emotional regulation training in anger management and emotion regulation difficulties in adolescents by means of body postures, breathing pattern, and facial expressions.Method: A quasi-experimental research design along with pretest-posttest and control group was employed for the conduct of this study. For this purpose, the number of 50 adolescents was selected via purposive sampling through screening based on inclusion and exclusion criteria. These participants were randomly assigned to experimental and control groups and the experimental group then received 8 sessions of emotion regulation training. In this period, the control group received the treatment unrelated to emotion regulation training. Both groups were assessed in terms of Difficulties in Emotion Regulation Scale (DERS) and State-Trait Anger Expression Inventory-2 (STAXI-2) before and after the treatment as well as in the three-month follow-up. The collected data were analyzed by descriptive and inferential statistics, including covariance analysis.Results: Data analysis showed that emotion regulation training has a significant effect on anger management and components emotion regulation difficulties in adolescents.Conclusion: As per the results of this study, it is recommended that emotion regulation training be extensively conducted in the form of educational and training programs for adolescents, especially in schools.
Speculation in Commodity Futures Markets, Inventories and the Price of Crude Oil
Authors: Byun Sung Je
Published: October 2016

This paper examines the role of inventories in refiners’ gasoline production and develops a structural model of the relationship between crude oil prices and inventories. Using data on inventories and prices of oil futures, I show that convenience yields decrease at a diminishing rate as inventories increase, consistent with the theory of storage. In addition to exhibiting seasonal and procyclical behaviors, I show that the historical convenience yield averages about 18 percent of the oil price from March 1989 to November 2014. Although some have argued that a breakdown of the relationship between crude oil inventories and prices following increased financial investors’ participation after 2004 was evidence of a speculative effect, I find that the proposed price-inventory relationship is stable over time. The empirical evidence indicates that crude oil prices remained tied to oil-market fundamentals such as inventories, suggesting that the contribution of financial investors’ activities was weak.
Computational Antioxidant Capacity Simulation (CAOCS) Assay of Catechol, Resorcinol and Hydroquinone
Authors: Idowu Sunday Olakunle , Adeyemo Morenikeji Ayodele
Published: October 2016

There is an urgent need for a biorelevant antioxidant capacity assay, which is crucial to quality-assured polyphenol dietary supplements. We hypothesize that the 'position', more than the 'number' of phenolic groups, is critical to the antioxidant capacity of polyphenols. Computational Antioxidant Capacity Simulation (CAOCS) assay was implemented to test the hypothesis, while refinement of existing assay protocol was aimed at reducing the cost of analysis. The antioxidant capacities of resorcinol, catechol and hydroquinone (3 diphenol positional isomers) were determined by CAOCS assay. Photometric titration experiments and associated informatics that constitute CAOCS assay were evaluated through the use of small increments (< 1 mL) of antioxidant solution. Antioxidant capacity ranking of the positional isomers was found to be; hydroquinone > catechol > resorcinol, (60/g, 46/g and 28/g respectively). The relative bond strength of the phenolic groups, which governs the ranking, was accounted for by structural theory. Optimal 250 ÂµL increment of antioxidant solution afforded a 75% reduction of the amount of antioxidant required in the original assay protocol, where a 1 mL increment was used. CAOCS values vary widely for the positional isomers. The unique structure-antioxidant capacity-correlation (SACC) which confirmed our hypothesis is a signature of biorelevance. Significantly, microliter increments reduced the amount of active material required and hence, the cost of analysis. The methodology is thus attractive for profiling exotic and more expensive polyphenols. CAOCS assay holds a great promise of enabling quality-by-design (QbD) of polyphenol dietary supplements.

Langlands parameters of derived functor modules and Vogan diagrams
Authors: Friedman Paul D.
Published: October 2016

Let $G$ be a linear reductive Lie group with finite center, let $K$ be a maximal compact subgroup, and assume that $\mathrm{rank } G = \mathrm {rank } K$. Let $\ g= l\oplus u$ be a $\theta$ stable parabolic subalgebra obtained by building $l$ from a subset of the compact simple roots and form $A_g(\lambda)$. Suppose $\Lambda=\lambda+2\delta( u\cap p)$ is $K$-dominant and the infinitesimal character, $\lambda+\delta$, of $A_{g}(\lambda)$ is nondominant due to a noncompact simple root. By interpreting these conditions on the level of Vogan diagrams, a conjecture by Knapp is (essentially) settled for the groups $G=SU(p,q),\, Sp(p,q)$, and $SO^*(2n)$, thereby determining the Langlands parameters of natural irreducible subquotient of $A_{ g}(\lambda)$. For the remaining classical groups, simple supplementary conditions are given under which the Langlands parameters may be determined.
Locally compact quantum groups in the von Neumann algebraic setting
Authors: Kustermans Johan , Vaes Stefaan
Published: October 2016

In this paper we complete in several aspects the picture of locally compact quantum groups. First of all we give a definition of a locally compact quantum group in the von Neumann algebraic setting and show how to deduce from it a $C^*$-algebraic quantum group. Further we prove several results about locally compact quantum groups which are important for applications, but were not yet settled in our paper [8]. We prove a serious strengthening of the left invariance of the Haar weight, and we give several formulas connecting the locally compact quantum group with its dual. Loosely speaking we show how the antipode of the locally compact quantum group determines the modular group and modular conjugation of the dual locally compact quantum group.
Affine-Distance symmetry sets
Authors: Giblin P. J. , Holtom P. A.
Published: October 2016

The affine distance symmetry set (ADSS) of a plane curve is an affinely invariant analogue of the euclidean symmetry set (SS) [7], [6]. We list all transitions on the ADSS for generic 1-parameter families of plane curves. We show that for generic convex curves the possible transitions coincide with those for the SS but for generic non-convex curves, further transitions occur which are generic in 1-parameter families of bifurcation sets, but are impossible in the euclidean case. For a non-convex curve there are also additional local forms and transitions which do not fit into the generic structure of bifurcation sets at all. We give computational and experimental details of these.
Nuclear and integral polynomials on testing $\mathsf C^{(I)}, \;\; I$ uncountable
Authors: Boyd Christopher
Published: October 2016

We show that for $I$ an uncountable index set and $n\ge 3$ the spaces of all $n$-homogeneous polynomials, all $n$-homogeneous integral polynomials and all $n$-homogeneous nuclear polynomials are all different. Using this result we then show that the class of locally Asplund spaces is not preserved under uncountable locally convex direct sums nor is separably determined.
Bounded distributive lattice expansions
Authors: Gehrke Mai , Jónsson Bjarni
Published: October 2016

A new notion of a canonical extension $\mathbf{A}^{\sigma }$ is introduced that applies to arbitrary bounded distributive lattice expansions (DLEs) $\mathbf{A} $. The new definition agrees with the earlier ones whenever they apply. In particular, for a bounded distributive lattice $\mathbf{A}, \mathbf{A}^{\sigma }$ has the same meaning as before. A novel feature is the introduction of several topologies on the universe of the canonical extension of a DL. One of these topologies is used to define the canonical extension $f^{\sigma }:\mathbf{A}^{\sigma }\rightarrow \mathbf{B}^{\sigma }$ of an arbitrary map $f:\mathbf{A}\rightarrow \mathbf{B}$ between DLs, and hence to define the canonical extension $\mathbf{A}^{\sigma }$ of an arbitrary DLE $\mathbf{A}$. Together the topologies form a powerful tool for showing that many properties of DLEs are preserved by canonical extensions.

In this paper we address the classical question going back to S. Bochner and H. L. Krall to describe all systems $\{p_{n}(x)\}_{n=0}^\infty$ of orthogonal polynomials (OPS) which are the eigenfunctions of some finite order differential operator. Such systems of orthogonal polynomials are called Bochner-Krall OPS (or BKS for short) and their spectral differential operators are accordingly called Bochner-Krall operators (or BK-operators for short). We show that the leading coefficient of a Nevai type BK-operator is of the form $((x - a)(x-b))^{N/2}$. This settles the special case of the general conjecture 7.3. of [4] describing the leading terms of all BK-operators.

Litteratur efter orientalismen
Authors: Hafez Sabry
Published: October 2016

Sabry Hafez: “Literature after Orientalism – The Enduring Lure of the Occident: Modernity, Canon and Translatability”After reflecting on the status and challenge of “world literature”, the article addresses three issues concerning orientalism: modernity, canon and translatability. The attraction to the West played a significant role in the formation of the modern Arabicliterary canon, despite Arabic culture’s long history and tradition of creating its own canon. Unlike the West, in which the concepts of canon and canonical literary texts goes only to the 18th century, Arabic culture has had its classics and classification of writers and works since pre-Islamic time and the idea of Mu’allaqat, when a few poems were selected to be hung on the walls of the Ka‘bah. The concept of classics, and the formation of the literary canon in the modern period, benefitted from some of the achievements of the past, but had its eyes on the occident, which was clearly in the desire to have works recognised by the West, first by its specialists, read orientalists, then by its literary circles. The intervention of the international literary field led to a crisis of canon and a distortion of the literary field in Arabic culture, which was already distorted by the intervention of the establishment. Finally, the article considers the marginal role Arabic literature plays in world literature today.

Ellen Wulff: “Translating from the Arabic”This article deals with a translator’s problems when translating from the Arabic into Danish. The introduction presents the literary texts used as material and published in this edition of Passage, two chapters of the Libyan author Ibrahim al-Koni’s novel The Bleeding of the Stone. The first part discusses a translator’s difficulties due to disparity between grammatical structures in Semitic and Indo European languages, the second part difficulties due to divergent concepts of ‘good language’.

Sejl i jorden

Nathalie Khankan: “Sails in the Soil”In standard accounts of Palestinian literature, literary expression invariably figures as national allegory, rarely explaining meaning as it is created in the text. This article problematizes the categories used by historiographers to describe Palestinian literature. It does so through the site of the so-called New 1990s Poets, whose texts upset monolithic literary narratives. At the same time these poems also help us better understand the endurance of that overriding tension in Palestinian cultural production between the political and collective pressures of the text on the one hand and more personal, subjective figurations on the other.

Hullet i nullerne. Ind og ud af kunsten med performativ biografisme
Authors: Haarder Jon Helt
Published: October 2016

Jon Helt Haarder: “The Hole in the 00s: In and Out of Art with Performative Biographism”The hole mentioned in the title refers to the breaking down of barriers between art and life. This project of the historical avant-garde as it has resurfaced in the relational art practices of the 1990s is used as one way of framing a dominating trend in Scandinavian literature around the turn of the century: “Performative biographism” is suggested as a label for the widespread use of biographical or autobiographical material for artistic purposes. Authors and texts treated or mentioned include work by Peter Høeg, Suzanne Brøgger, Jørgen Leth, Das Bechwerk, Carina Rydberg, Karl Ove Knausgård, Kristian Ditlev Jensen, Knud Romer, Kim Leine – and August Strindberg.
Ekshibitionistiske selvudslettelser. Autoreception og genskrivning hos Jørgen Leth og clausbeck-nielsen.net

Stefan Iversen: “Exhibitionistic Erasures of the Self: Autoreception and Re-writing in Works by Jørgen Leth and clausbeck-nielsen.net”Taking its point of departure in the observation that recent Scandinavian literature and art have seen an increase in the number of works dealing with transgressions of the divide between the work of art as an autonomous entity and the artist as a concrete individual, this article sets out to investigate what it terms ‘autoreception’ and ‘rewriting’ in two already canonical works by Jørgen Leth and clausbeck-nielsen.net. The main argument is that not only are these two works composed by using a rewriting strategy, they also draw a lot of their highly original aesthetic and ethic impetus from it.
