ON THE SINGULARITIES OF THE ZETA AND ETA FUNCTIONS OF AN ELLIPTIC OPERATOR
Authors: LOYA PAUL , MOROIANU SERGIU , PONGE RAPHAËL 
Published: August 2011

Let P be a self-adjoint elliptic operator of order m > 0 acting on the sections of a Hermitian vector bundle over a compact Riemannian manifold of dimension n. General arguments show that its zeta and eta functions may have poles only at points of the form [Formula: see text], where k ranges over all nonzero integers ≤ n. In this paper, we construct elementary and explicit examples of perturbations of P which make the zeta and eta functions become singular at all points at which they are allowed to have singularities. We proceed within three classes of operators: Dirac-type operators, self-adjoint first-order differential operators and self-adjoint elliptic pseudodifferential operators. As consequences, we obtain genericity results for the singularities of the zeta and eta functions in those settings. In particular, in the setting of Dirac-type operators we obtain a purely analytical proof of a well-known result of Branson–Gilkey [Residues of the eta function for an operator of Dirac type, J. Funct. Anal. 108(1) (1992) 47–87], which was obtained by invoking Riemannian invariant theory. As it turns out, the results of this paper contradict Theorem 6.3 of [R. Ponge, Spectral asymmetry, zeta functions and the noncommutative residue, Int. J. Math. 17 (2006) 1065–1090]. Corrections to that statement are given in this paper.

Published: August 2011

SummaryModerate alcohol consumption has been shown to protect against cardiovascular diseases. The association between alcohol consumption, especially types of alcoholic beverages, and venous thromboembolism (VTE) is less well described. The aim of this study was to investigate the impact of alcohol consumption and different alcoholic beverages on risk of VTE. Information on alcohol consumption was collected by a selfadministrated questionnaire in 26,662 subjects, aged 25–97 years, who participated in the Tromsø Study, in 1994–1995. Subjects were followed through September 1, 2007 with incident VTE as the primary outcome. There were 460 incident VTE-events during a median of 12.5 years of follow-up. Total alcohol consumption was not associated with risk of incident VTE. However, subjects consuming ≥3 units of liquor per week had 53% increased risk of VTE compared to teetotalers in analyses adjusted for age, sex, body mass index, smoking, diabetes, cancer, previous cardiovascular disease, physical activity and higher education (HR: 1.53, 95% CI: 1.00–2.33). Contrary, subjects with a wine intake of ≥3 units/week had 22% reduced risk of VTE (HR: 0.78, 95% CI: 0.47–1.30), further adjustment for liquor and beer intake strengthened the protective effect of wine (HR: 0.53, 95% CI: 0.30–1.00). Frequent binge drinkers (≥1/week) had a 17% increased risk of VTE compared to teetotallers (HR 1.17, 95% CI: 0.66–2.09), and a 47% increased risk compared to non-binge drinkers (HR 1.47, 95% CI: 0.85–2.54). In conclusion, liquor consumption and binge drinking was associated with increased risk of VTE, whereas wine consumption was possibly associated with reduced risk of VTE.

The Shift of Labor Market Risks in Deindustrializing Taiwan, Japan, and Korea
Authors: Lee Sophia Seung-yoon 
Published: August 2011

AbstractThis paper has three objectives: i) to empirically examine labor market transitions in deindustrializing Asian economies; ii) to study the character of labor market risks and how these risks are shifting by gender, by education level, and by age in the transitional period; and iii) to rethink the commonly accepted assumptions that deindustrialization and globalization are the main causes of new labor market risks and, thus propose the possibility of institutional legacy as an important factor for such risk shifts. This study focuses on the labor market risks in the Republic of Korea, Japan, and Taiwan. Three steps are taken in this inquiry. First, this study commences by empirically examining the three labor market changes mentioned above. Second, it challenges the idea of the emergence of “new risks,” arguing instead for the concept of “risk shift”: the feature of risk shifting to different demographic groups. Lastly, with the empirical evidence already used, this paper discusses whether deindustrialization or globalization is a sufficient cause for risk shifts in deindustrializing Asian economies, proposing that institutional legacy may be an important factor in risk shift.
On the Image of Painting
Authors: Benjamin Andrew 
Published: August 2011

AbstractPainting can only be thought in relation to the image. And yet, with (and within) painting what continues to endure is the image of painting. While this is staged explicitly in, for example, paintings of St. Luke by artists of the Northern Renaissance—e.g., Rogier van der Weyden, Jan Gossaert, and Simon Marmion—the same concerns are also at work within both the practices as well as the contemporaneous writings that define central aspects of the Italian Renaissance. The aim of this paper is to begin an investigation into the process by which painting stages the activity of painting. This forms part of a project whose aim is an investigation of the way philosophy should respond to the essential historicity of art (where the latter is understood philosophically).
Displacements—Beyond the Coloniality of Images
Authors: Vallega Alejandro A. 
Published: August 2011

AbstractDynamic mental images are co-constitutive of the determinations of reality and possibility under which our senses of life open and unfold. Ultimately, this dynamic sense of images introduces the difficulty of thinking in light of their role in the configuration of human knowledge and their power over interpretations and determinations of the many senses of beings. This relationship between images and philosophical knowledge is further complicated when one looks at it from the perspective of a colonized consciousness. In such cases self-knowledge and the very possibility of philosophical knowledge depend on images that are not one’s own. This makes the articulation of the senses of distinct existences an impossible project. By looking at the work of Fanon, Anibal Quijano, and Alfredo Jaar, this article discusses how such pernicious images occur in spite of one’s distinct sense of existence, and how the distorted displacement of existence may be challenged and overcome.
Pause of Participation. On the Function of Artificial Presence
Authors: Wiesing Lambert 
Published: August 2011

AbstractThe foundation of phenomenological image theories is the view that image perception leads to a perception sui generis. In order to grasp this peculiarity of image perception, two ways have traditionally been considered: either through a description of the particular object of image perception or through a description of the unique origin of image perception. This article explores a third way within the phenomenology of the image by trying to determine the uniqueness of image perception through its peculiar, necessary effects on the observer of the image. The thesis is: The observer of an image does not become an image object in the image. It is only in the case of image perception that there is relief through a gap in participation. It is the perception of something without the demand, as the perceiving person, of being physically involved in what is perceived.
La relativité du Temps et de l’Espace dans le théâtre lā-maqūl de Tawfīq al-akīm
Authors: Denooz Laurence 
Published: August 2011

AbstractA comparison of The Tree Climber with other plays by Tawfīq al-Ḥakīm (1898-1987) tends to challenge claims that it is a pivotal text in the author’s literary career, and an emblem of Absurdism. Tawfīq al-Ḥakīm himself associates his play with a form of “intellectual popular irrealism” or “irrational theater”, which three distinct elements of his work come to confirm: a) the recurrence of the juxtaposition of two animated short scenes, distinct in both Time and Space; b) the invariability of his philosophical and political message throughout his work; c) the unending fight against spatio-temporal Determinism, coupled with the repeated affirmation of the relativity of the perception of Time and Space.

Two Identical Manuscripts from the Library of Raphael de Mercatellis? The relationship between MSS 11 and 17 in the University Library of Ghent
Authors: van Bergen Saskia 
Published: August 2011

AbstractThe library of Raphael de Mercatellis (1437-1508), natural son of Philip the Good of Burgundy and abbot of St Bavon in Ghent, contains two manuscripts that are similar in both design and content. The manuscripts are preserved as Ghent, UL, MSS 11 and 17. Both were ordered by De Mercatellis around 1500 and contain as main text the Monotessaron, a well-known Gospel Harmony by Johannes Gerson. The text is in both cases supplemented with an extensive set of fragments and glosses, and more than 130 full-page miniatures. Codicological analysis of the manuscripts reveals what went wrong in the planning and copying process of MS 17, because of which the production of MS 11 became inevitable.

From ICSID Annulment to Appeal Half Way Down the Slippery Slope
Authors: Schreuer Christoph 
Published: August 2011

AbstractAnnulment under the ICSID Convention offers a limited remedy on the basis of a few carefully circumscribed grounds. Recently, losing parties have attacked awards for a wide array of reasons. Some ad hoc committees deciding these requests for annulment have taken a broad view of their powers. They have given some grounds for annulment an extremely wide interpretation thereby blurring the line between annulment and appeal. For instance, a perceived mistake in the interpretation of a rule of law has been regarded as an excess of powers for failure to apply the proper law. One ad hoc committee went beyond the reasons for annulment put forward by the applicant. It actively searched for additional grounds and eventually annulled the award for a reason not relied upon by the applicant. Some ad hoc committees have gone beyond the task given to them by the ICSID Convention, offering general criticism and advice to tribunals. The risk that an ICSID award will be annulled is now higher than that a non-ICSID award will be set aside by a competent domestic court.
International Water R esources Law and the International Law Commission Draft Articles on Transboundary Aquifers: A Missed Opportunity for Cross-Fertilisation?
Authors: McIntyre Owen 
Published: August 2011

AbstractWhile the Draft Articles on the Law of Transboundary Aquifers adopted in 2008 by the International Law Commission (ILC)1 follow the same format as the 1997 UN Watercourses Convention2 and might reasonably have been expected to adopt a similar normative approach wherever possible, the Preamble to the Draft Articles fails to make any reference to this or to other seminal instruments or codifications in the area of international water resources law and the document takes, in some respects, a radically different and less progressive stance. The principal difference in the Draft Articles, and one which can be linked to most of the other deviations, is the inclusion of an express reference to the sovereignty of aquifer States in a manner implying that this is the key guiding principle of the instrument. This emphasis on State sovereignty over shared, and often migratory, water resources appears to represent something of a retreat from the distributive equity inherent in the firmly established principle of equitable and reasonable utilization and from the intense procedural and institutional cooperation required to achieve the community of interests approach necessary to give meaning to this principle. Reliance on sovereignty implies instead a drift towards a position based more on the narrow and immediate self-interest of States. In order to avoid such an interpretation, it would have been better if the Draft Articles had sought to establish two separate but parallel regimes, one based on sovereignty and covering the static geological formation of the aquifer, and one covering the shared water resources contained in, and transiting through, the formation and based on equitable and reasonable utilization.
The Black Death in Hebrew Literature: Ha-Maamar Be-Qaddaat Ha-Dever (Treatise on Pestilential Fever)
Authors: Bos Gerrit 
Published: August 2011

AbstractHa-Maamar be-Qaddaat ha-dever (Treatise on Pestilential Fever), composed by an anonymous author, is one of several treatises devoted to the subject of plague that exist in Hebrew literature. The treatise is basically a concise regimen of health as it was common throughout the Middle Ages that has been adapted to the special case of the plague and that has been supplemented with a final section of remedies for the time of the plague. Although we do not know the name of the author nor where and when he lived and composed the treatise, we can draw some conclusions from the foreign, non-Hebrew terminology used in the treatise. As several of the foreign terms used for the different plants and remedies are in old Spanish, it seems reasonable to suppose that the author hailed from the Iberian Peninsula and possibly composed the treatise there as well. The frequent quotations in the supplementary section 21 from Spanish Islamic physicians like Ibn Rushd, al-Zahrāwī, al-Ghāfiqī and above all Ibn Zuhr also confirm such a supposition.
Orthodox strategies in the research of the Wissenschaft des Judentums
Authors: Yedidya Asaf 
Published: August 2011

AbstractThis article deals with the attempts of Orthodox scholars, at the end of the nineteenth and the first third of the twentieth century, to create an Orthodox alternative to the Wissenschaft des Judentums (‘Science of Judaism’). On the one hand, those “experiments” clearly differed from their non-Orthodox equivalents, and on the other from the (un-researched) Orthodox historiography, which was created to serve as an alternative to existing Wissenschaft des Judentums investigations. The Orthodox scholars competed with the basic values and methods of research which challenged traditional concepts of the past, such as objectivity and historicism, and developed research strategies that allowed them to hold on to their two objectives at the same time, i.e. both scientific research methods and traditional values.
Siddi Street Theatre and Dance in North Karnataka, South India
Authors: Obeng Pashington 
Published: August 2011

AbstractThe Karnataka African Indians (Siddis, Habshis and Cafrees), drawing on both Indian performing arts and their African heritage, use dance and street theatre for political action, entertainment, social critique and self-expression. This paper focuses on Siddi dance and theatre in Uttara Kannada (North Karnataka), South India. Karnataka Siddis number about twenty thousand (Prasad, 2005). Using dramatic aesthetics, performers portray farming, hunting, child labour, violence against women and domestic work motifs to articulate Siddi grundnorms (foundational norms). I address how some Siddi dances and street theatre parallel and yet may differ from other performing arts in South India. Further, the paper complicates the current discourse on how diasporic African communities use the performing arts. My paper goes beyond the Atlantic Diaspora model. It examines ways in which Siddis of South Asia use their dance and theatre to express multiple domains of cultural art forms alongside the everyday use of such performances including a counter-hegemonic stance.
A West African Sufi Master on the Global Stage: Cheikh Abdoulaye Dièye and the Khidmatul Khadim International Sufi School in France and the United States
Authors: Babou Cheikh A. 
Published: August 2011

AbstractThe recent wave of West African Muslim migration to the West started after the Great War and gained momentum in the 1960s. Sub-Saharan Africans have been particularly successful in finding a niche in Europe and North America partly because of the connection between immigrants and centers of Islamic spirituality and knowledge in Africa provided by a dynamic leadership that straddles the three continents. Based on extensive interviews in the United States and in France and on the examination of Murid internal sources and scholarly secondary literature, this article investigates the efforts of the late Sufi sheikh, Abdoulaye Dièye, to expand the Muridiyya Muslim tariqa in France and North America. I am particularly interested in examining the foundations of Dièye’s appeal, his struggle to earn legitimacy and relevance on the global stage, and the response of diverse constituencies to his calling. I contend that the attraction of Dièye’s teachings to Europeans, Americans, and Africans in the diaspora, is rooted in his dual cultural outlook as a Western educated and traditionally trained Murid.
Beyond Abject Spaces: Enterprising Zimbabwean Diaspora in Britain
Authors: Mbiba Beacon 
Published: August 2011

AbstractThe concept of space in relation to the experiences of African immigrants in Britain has been the focus of recent geographical and development studies with Joann McGregor’s notion of abject spaces the most provocative. This paper considers how the concept of abject spaces can be extended beyond the existence of the marginal, illegal and undocumented immigrants to explore opportunities for entrepreneurship within and beyond these spaces. Based on observation and in-depth interviews with forty entrepreneurs in the same Zimbabwean immigrant community studied by McGregor, the paper demonstrates connections between the businesses formed to serve abject spaces as well as the ways in which living in the same abject space stimulates entrepreneurship. Abject spaces are simultaneously business spaces in ways that demonstrate the innovation and agency of immigrants and the connections between abject spaces and both the country of origin and host community spaces. This contributes to a better understanding of contemporary migration especially the temporality or space-time dimension of abjection and the significance of small immigrant enterprises in Britain.1
Cerebral Correlates and Statistical Criteria of Cross-Modal Face and Voice Integration
Authors: Pollick Frank , Love Scott , Latinus Marianne 
Published: August 2011

AbstractPerception of faces and voices plays a prominent role in human social interaction, making multisensory integration of cross-modal speech a topic of great interest in cognitive neuroscience. How to define potential sites of multisensory integration using functional magnetic resonance imaging (fMRI) is currently under debate, with three statistical criteria frequently used (e.g., super-additive, max and mean criteria). In the present fMRI study, 20 participants were scanned in a block design under three stimulus conditions: dynamic unimodal face, unimodal voice and bimodal face–voice. Using this single dataset, we examine all these statistical criteria in an attempt to define loci of face–voice integration. While the super-additive and mean criteria essentially revealed regions in which one of the unimodal responses was a deactivation, the max criterion appeared stringent and only highlighted the left hippocampus as a potential site of face– voice integration. Psychophysiological interaction analysis showed that connectivity between occipital and temporal cortices increased during bimodal compared to unimodal conditions. We concluded that, when investigating multisensory integration with fMRI, all these criteria should be used in conjunction with manipulation of stimulus signal-to-noise ratio and/or cross-modal congruency.
Partitioning Contrast or Luminance Disparity into Perceived Intensity and Rotation
Authors: Hetley Richard , Stine Wm Wren 
Published: August 2011

AbstractWhile most of the work on stereopsis focuses on geometric disparities, humans also respond to intensity (contrast or luminance) disparities in the absence of geometric disparities. A rectangular-wave grating viewed with an intensity disparity engenders two perceptions: a perceived intensity, and a perceived rotation of the individual bars of the grating (the Venetian blind effect). Measuring perceived intensity and perceived rotation in gratings with intensity disparities, we found that the two degrees of freedom from the intensities presented to each eye are conserved in the form of two perceptions: perceived intensity is related to the sum of the grating intensities and perceived rotation is related to the difference. Perceived rotation as a function of intensity disparity was then modeled as a simple difference in the neural response of each eye. Perceived contrast and brightness as a function of intensity disparity were modeled using the two-stage gain-control model.
Anomalous Auditory Cortex Activations in Colored Hearing Synaesthetes: An fMRI-Study

AbstractColor percept induction in synaesthetes by hearing words was previously shown to involve activation of visual and specifically color processing cortex areas. While this provides a rationale for the origin of the anomalous color percept the question of mechanism of this crossmodal activation remains unclear. We pursued this question with fMRI in color hearing synaesthetes by exposing subjects to words and tones. Brain activations in word condition accompanied by highly reliable color percepts were compared with activations in tone condition with only occasional color percepts and both contrasted to activations in normal subjects under the same stimulus conditions. This revealed that already the tone condition similar to the word condition caused abnormally high activations in various cortical areas even though synaesthetic percepts were more rare. Such tone activations were significantly larger than in normal subjects in visual areas of the right occipital lobe, the fusiform gyrus, and the left middle temporal gyrus and in auditory areas of the left superior temporal gyrus. These auditory areas showed strong word and tone activation alike and not the typically lower tone than word activation in normal subjects. Taken together these results are interpreted in favour of the disinhibited feedback hypothesis as the neurophysiological basis of genuine synaesthesia.
