Risk and Uncertainty

description: Large and unpredictable swings in fuel prices create financial uncertainty to airlines. While there are the risks for going unhedged, airlines that hedge to mitigate fuel price risk face the basis risk. This paper examines whether the length of hedge horizon and distance to contract maturity affect the effectiveness of jet fuel cross hedging. Understanding the effects of hedge duration and futures contract maturity helps improve airline?s fuel hedging strategies. We find that (1) regardless of the distance to contract maturity, weekly hedge horizon has the highest effectiveness for jet fuel proxies like heating oil, Brent, WTI, and gasoil; (2) heating oil is the best jet fuel proxy for all hedge horizons and contract maturities; and (3) the hedge effectiveness of heating oil is higher for one-month and three-month contracts.

description: This study minimizes total cost for single-feedstock supply chains of two dedicated energy crops, perennial switchgrass and biomass sorghum, in Tennessee using a spatial optimization model. Greenhouse gas emissions from the transport of feedstock to the conversion facility were estimated for respective feedstock supply chains. Results show that different demand for land types from two feedstocks and the geographically diverse landscape across the state affect the economics of bioenergy crops supply chains and feedstock transportation emissions. Switchgrass is more suitable than biomass sorghum for biofuel production in Tennessee based on the supply chains cost and feedstock hauling emissions.

description: As an unstable light pure leptonic system, positronium is a very specific probe atom to test bound state QED. In contrast to ordinary QED for free leptons, the bound state QED theory is not so well understood and bound state approaches deserve highly accurate tests. We present a brief overview of precision studies of positronium paying special attention to uncertainties of theory as well as comparison of theory and experiment. We also consider in detail advantages and disadvantages of positronium tests compared to other QED experiments.

description: Abstract

With the changing dynamics of evaluating faculty productivity that has been a matter of discussion across all academic institutions, there is a need to understand the various components of Faculty productivity that have changed over a period of time. The productivity in research related aspects is one such dimension which needs to be thoroughly looked at considering the fact that the productivity in research is a direct measure of innovation of an Institute and that of the University and Society at large. While research productivity basically gets influenced by a lot of factors, those that pertain to the institution are of paramount importance as the variations in the institutional support could have a direct bearing on the faculty research performance. While this is true for all kinds of educational institutions of higher education, engineering domain has gained tremendous significance in the recent past as far as the research related outcomes are concerned amongst the faculty members. The objective of the present research is thus to understand the intricate role of Institution Support encompassing: leadership, environment and facilities on the research productivity of faculty in engineering Institutes.  A multi-state stratified random sampling was employed to collect data from 381 faculties. The data was collected from the questionnaire method and was analyzed through tools such as descriptive statistics and correlations. Furthermore, confirmatory factor analysis and multiple regression techniques were employed to understand the intricate role of the components of institutional support on faculty research productivity. The results reveal that all the components of institutional support had a direct bearing on the research productivity of Faculty at large and were instrumental enough in explaining the variations in the productivity in research emphasis and culture for the institutions as a whole.
title: Characterisation of host immune responses to Burkholderia mallei
Creators: name: Rowland, Caroline A.
Publisher: name: The Open University
Year: 2006

description: Burkholderia mallei is an intracellular, gram-negative bacterium which causes the disease Glanders in humans and mice. Little research has been performed to examine host immune responses to this organism. Therefore, the purpose of this work was to characterise host immunity to B. mallei by analysing splenic cellular and cytokine responses and systemic cytokine responses during intra-peritoneal infection in BALB/c mice. In summary, chronic B. mallei infection was characterised by an initial period of bacterial colonisation which was limited by the host immune system. This was followed by extensive bacterial replication within abscessed spleens. IFN-γ was essential for controlling early infection and was accompanied by expression of type 1 cytokines and macrophage and neutrophil activation within 24 hours post-infection (p.i.). The IFN-γ response was induced predominantly in NK cells by IL-12 and IL-18 in vitro, further demonstrating the requirement for type 1 immunity to B. mallei infection. TNFα and Gr-1+ cells (predominantly neutrophils) were also important in innate host immune responses. T cells were not important during this phase but played an important role in adaptive immune responses to infection. Downregulation of immune responses occurred 72h p.i. followed by an additional period of macrophage and neutrophil activation 5-7 days p.i.. A heterogeneous infection developed 14-36 days p.i., with mice either forming abscesses or apparently clearing the infection. Abscesses were associated with high bacterial loads and inflammation: TNFα and T cells were involved in controlling the infection, although this did not prevent bacterial colonisation or eventual lethality 8 weeks p.i.. In conclusion, this data shows that early, type 1 immune responses are ultimately overcome leading to extensive replication of B. mallei within abscessed tissues. Maintenance of the type 1 cell-mediated immune responses observed during early infection is likely to be crucial for the development of effective therapies and vaccines against B. mallei.
Structural diversity of disc galaxies originating in the cold gas inflow from cosmic webs
Creators: name: Noguchi, Masafumi
Publisher: name: arXiv
Year: 2020
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Disc galaxies show a large morphological diversity with varying contribution of three major structural components; thin discs, thick discs, and central bulges. Dominance of bulges increases with the galaxy mass (Hubble sequence) whereas thick discs are more prominent in lower mass galaxies. Because galaxies grow with the accretion of matter, this observed variety should reflect diversity in accretion history. On the basis of the prediction by the cold-flow theory for galactic gas accretion and inspired by the results of previous studies, we put a hypothesis that associates different accretion modes with different components. Namely, thin discs form as the shock-heated hot gas in high-mass halos gradually accretes to the central part, thick discs grow by the direct accretion of cold gas from cosmic webs when the halo mass is low, and finally bulges form by the inflow of cold gas through the shock-heated gas in high-redshift massive halos. We show that this simple hypothesis reproduces the mean observed variation of galaxy morphology with the galaxy mass. This scenario also predicts that thick discs are older and poorer in metals than thin discs, in agreement with the currently available observational data.

We give a criterion for a dimension to be of finite type. We also characterize those dimensions of finite type, for which there is an indecomposable representation of this dimension, and show that there can be at most one indecomposable representation of any dimension of finite type. Moreover, if such a representation exists, it only has scalar endomorphisms.

The Stock Market’s Valuation of R&D and Market Concentration in Horizontal Mergers
Creators: name: Sonenshine, Ralph
Publisher: name: American University
Year: 2023

description: It is well documented that acquirers often pay a very large premium to acquire companies in related industries. There are many explanations as to the source of this premium. This study isolates two variables, R&D-intensity and market concentration, and correlates their value individually and jointly to the value of the acquired company. The results indicate that change in market concentration and R&D is positively correlated to the merger deal premium in a horizontal merger. Furthermore, deal premiums tend to follow an inverted U curve pattern relative to market concentration change. The study also shows that cost synergies and macro economic growth impact deal premium values. Key words: mergers, R&D, market concentration, deal premium

description: Naively, a resolution of the black hole information paradox appears to involve microscopic details of a theory of quantum gravity. However, recent work has argued that a unitary Page curve can be recovered by including novel replica instantons in the gravitational path integral. Moreover, replica instantons seem to rely on disorder averaging the microscopic theory, without a definite connection to a single, underlying unitary quantum system. In this letter, we show that disorder averaging and replica instantons emerge naturally from a gravitational effective theory built out of typical microscopic states. We relate replica instantons to a moment expansion of the simple operators appearing in the Eigenstate Thermalization Hypothesis, describe Feynman rules for computing the moments, and find an elegant microcanonical description of replica instantons in terms of wormholes and Euclidean black holes.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We present new observations, carried out with IRAM NOEMA, of the atomic neutral carbon transitions [CI](1-0) at 492 GHz and [CI](2-1) at 809 GHz of GN20, a well-studied star-bursting galaxy at $z=4.05$. The high luminosity line ratio [CI](2-1)/[CI](1-0) implies an excitation temperature of $48^{+14}_{-9}$ K, which is significantly higher than the apparent dust temperature of $T_{\rm d}=33\pm2$ K ($β=1.9$) derived under the common assumption of an optically thin far-infrared dust emission, but fully consistent with $T_{\rm d}=52\pm5$ K of a general opacity model where the optical depth ($τ$) reaches unity at a wavelength of $λ_0=170\pm23$ $μ$m. Moreover, the general opacity solution returns a factor of $\sim 2\times$ lower dust mass and, hence, a lower molecular gas mass for a fixed gas-to-dust ratio, than with the optically thin dust model. The derived properties of GN20 thus provide an appealing solution to the puzzling discovery of starbursts appearing colder than main-sequence galaxies above $z>2.5$, in addition to a lower dust-to-stellar mass ratio that approaches the physical value predicted for starburst galaxies.

description: Angular distributions of the elastic and inelastic deuteron-nucleus scattering off $^{24}$Mg, $^{28}$Si, $^{58}$Ni, $^{90}$Zr, $^{116}$Sn, and $^{208}$Pb have been measured at a beam energy of 98 MeV/nucleon, with the goal of constraining the deuteron optical potential in this kinematical regime, and to extract the reduced transition probabilities for the ground-state transitions to low-lying excited states of these nuclei. Two potential models were used in the analysis of the measured $(d,d)$ and $(d,d')$ data within the optical model and the distorted-wave Born approximation: the phenomenological optical model potential associated with the collective model of nuclear scattering, and the semi-microscopic double-folding model of the deuteron-nucleus potential based on a realistic density-dependent M3Y interaction. The deuteron optical potential and inelastic $(d,d')$ scattering form factors were calculated using these two potential models, allowing for a direct comparison between the potential models as well as the validation of the deduced $Eλ$ transition rates.

title: 'You've got to keep your head on': A study of the stories young male service users tell about the transition to fatherhood
Creators: name: Reeves, Jane
Publisher: name: The Open University
Year: 2006

description: Research on disadvantaged young fathers has been minimally addressed in the literature, particularly in the UK and especially with young men who are service users. This thesis, drawing on discourse theory, explores the descriptions of 16 white, socially excluded young men, aged 15-24, on the transition to fatherhood. The findings from the study, which uses a narrative methodological approach, indicate common themes from the stories of the young fathers, especially with regard to the high levels of disadvantage and social exclusion they had been exposed to, and the anti-social behaviour they described engaging in, prior to the birth of their child/ren. A significant proportion of young men, however, reported how important fatherhood had been in transforming their attitudes and behaviour and how they took their responsibilities as fathers seriously. In addition, the data details the social support systems which are described as being important to them (including some professional support) and the types of activities they describe engaging in as fathers. The study also argues for transparency in research processes with hard to reach young people and the importance of using a reflexive approach, particularly regarding the biographical and professional influences the researcher brings to the study.

description: We study the physical mechanisms that cause the offset between low-redshift and high-redshift galaxies on the [OIII]/H$β$ versus [NII]/H$α$ ``Baldwin, Phillips & Terlevich'' (BPT) diagram using a sample of local analogues of high-redshift galaxies. These high-redshift analogue galaxies are selected from the Sloan Digital Sky Survey. Located in the same region on the BPT diagram as the ultra-violet selected galaxies at $z\sim2$, these high-redshift analogue galaxies provide an ideal local benchmark to study the offset between the local and high-redshift galaxies on the BPT diagram. We compare the nitrogen-to-oxygen ratio (N/O), the shape of the ionising radiation field, and ionisation parameters between the high-redshift analogues and a sample of local reference galaxies. The higher ionisation parameter in the high-redshift analogues is the dominant physical mechanism driving the BPT offset from low- to high-redshift, particularly at high {\nii/\ha}. Furthermore, the N/O ratio enhancement also plays a minor role to cause the BPT offset. However, the shape of the ionising radiation field is unlikely to cause the BPT offset because the high-redshift analogues have a similar hard ionising radiation field as local reference galaxies. This hard radiation field cannot be produced by the current standard stellar synthesis models. The stellar rotation and binarity may help solve the discrepancy.

description: Over the last 40 years a number of scholars have called upon fellow criminologists to rethink the field’s priorities and methods, as well as the American criminal justice system and current punishment practices. Drawing on alternative criminologies, including constitutive and peacemaking criminologies, as well as the practice of reintegrative shaming, this paper presents a new model of criminal justice that combines aspects of adversarial, restorative, social, and transformative justice frameworks. The resulting “intersectional criminal justice” offers a holistic harm-reduction model that moves the focus of our criminal justice system away from “rough justice” and towards collective restorative healing and positive social change.

A Matrix Model Dual of Type 0B String Theory in Two Dimensions

Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We propose that type 0B string theory in two dimensions admits a dual description in terms of a one dimensional bosonic matrix model of a hermitian matrix. The potential in the matrix model is symmetric with respect to the parity-like Z_2 transformation of the matrix. The two sectors in the theory, namely the NSNS and RR scalar sectors correspond to two classes of operators in the matrix model, even and odd under the Z_2 symmetry respectively. We provide evidence that the matrix model successfully reconstructs the perturbative S-matrix of the string theory, and reproduces the closed string emission amplitude from unstable D-branes. Following recent work in two dimensional bosonic string, we argue that the matrix model can be identified with the theory describing N unstable D0-branes in type 0B theory. We also argue that type 0A theory is described in terms of the quantum mechanics of brane-antibrane systems.

description: We present a comparative analysis of the properties of AGN emitting at radio and X-ray wavelengths. The study is performed on 907 X-ray AGN and 100 radio AGN selected on the CDFS and UDS fields and makes use of new and ancillary data available to the VANDELS collaboration. Our results indicate that the mass of the host galaxy is a fundamental quantity which determines the level of AGN activity at the various wavelengths. Indeed large stellar masses are found to be connected with AGN radio emission, as virtually all radio-active AGN reside within galaxies of M*>10^{10} Msun. Large stellar masses also seem to favour AGN activity in the X-ray, even though X-ray AGN present a mass distribution which is more spread out and with a non-negligible tail at M*<10^{9} Msun. Stellar mass alone is also observed to play a fundamental role in simultaneous radio and X-ray emission: the percentage of AGN active at both wavelengths increases from around 1% of all X-ray AGN residing within hosts of M*<10^{11} Msun to about 13% in more massive galaxies. In the case of radio-selected AGN, such a percentage moves from about 15% to about 45% (but up to 80% in the deepest fields). Neither cosmic epoch, nor radio luminosity, X-ray luminosity, Eddington ratio or star-formation rate of the hosts are found to be connected to an enhanced probability for joint radio+X-ray emission of AGN origin. Furthermore, only a loose relation is observed between X-ray and radio luminosity in those AGN which are simultaneously active at both frequencies.

title: Advocacy for People with Learning Difficulties: The Role of Two Organisations
Creators: name: Tilley, Elizabeth Kate
Publisher: name: The Open University
Year: 2007

description: This thesis is about advocacy for people with learning difficulties. It has been undertaken through a detailed study of two different types of advocacy organisations - People's Voices (a situation-based, one-to-one advocacy group) and Talkback (a self-advocacy group). Both organisations are based in Buckinghamshire. The research had two main aims. The first was to explore the values, principles and theories that underpin the work of advocacy organisations, and to consider how they are borne out in practice. This required a thorough analysis of organisational processes and relationships between group members. The second aim was to assess how advocacy organisations interact with and are shaped by the wider environment. This involved an in-depth examination of the local (historical and socio-political) context, as well as relations between the groups and external stakeholders - in particular, statutory bodies. The research found that although members of advocacy groups are generally inspired by a similar vision, ideas about how this might be achieved varied among respondents. Whilst the groups were guided by a strong set of values and principles, these were sometimes difficult to implement in practice - particularly with regard to how advocacy organisations are run. The thesis also showed that whilst advocacy organisations can and do direct their own agenda, they also face pressures from the wider environment - most notably through commissioning arrangements. In this way the thesis shed light upon wider questions concerning the relationship between statutory bodies and the voluntary sector, in the health and social care field in England. The research revealed the complexity of advocacy organisations, and highlighted the need for more in-depth, localised studies.

title: High-resolution analysis of rapid climate change from Greenland ice cores
Creators: name: Thomas, Elizabeth Ruth
Publisher: name: The Open University
Year: 2006

description: Extreme shifts in the climate system have long been recognized but the timescales for most events are large, occurring over millennia or longer. There is however, growing evidence for abrupt shifts in the climate system on much shorter timescales of centuries, decades or even years. It is these abrupt climate changes that would have the biggest impact on modern society with a potentially large and catastrophic climate shift occurring within the human lifespan. In this thesis I investigate two large and abrupt climate oscillations, as observed in the Greenland ice core record. The first is the most prominent cold event to have occurred during the Holocene, the cold event 8,200 years ago (the 8.2 kyr event) and the second is one of the strongest and longest glacial oscillations, Dansgaard-Oeschger event 8 (DO-8). I present a collection of high-resolution chemistry and stable isotope records from the plateau of the Greenland ice cap during the cold event 8,200 years ago. Using a composite of 4 records, the cold event is observed as a 160.5 year period during which decadal-mean isotopic values were below average, within which there is a central event of 69 years during which values were consistently more than one standard deviation below the average for the preceding period. The results show clear evidence for colder temperatures and a decrease in snow accumulation rate. However, the changes in chemical concentrations for the ions looked at here are small, suggesting only minor changes in atmospheric circulation for this event. Apart from the decrease in methane concentration, Greenland ice cores give only weak evidence for effects outside the North Atlantic region. A new high-resolution chemical and stable isotope record is presented, from the North Greenland Ice Core Project (NGRIP) ice core, during Dansgaard-Oeschger event 8. The onset of DO-8 is first observed as a rapid decrease in chemical deposition to Greenland, indicating a large and abrupt shift in oceanic and atmospheric circulation. The change in the chemical deposition is followed over a decade later by an increase in temperature of approximately 13°C, from extreme cold stadial conditions to warm interstadial conditions, accompanied by a 33 % increase in annual snow accumulation. The transition is observed in the deuterium excess record as an abrupt shift to warmer source water conditions in the period after the chemical transition but considerably earlier than interstadial temperatures have been reached.

description: The central elements of the algebra of monodromy matrices associated with the $\mathbb{Z}_n$ R-matrix are studied. When the crossing parameter $w$ takes a special rational value $w=\frac{n}{N}$, where $N$ and $n$ are positive coprime integers, the center is substantially larger than that in the generic case for which the "quantum determinant" provides the center. In the trigonometric limit, the situation corresponds to the quantum group at roots of unity. This is a higher rank generalization of the recent results by Belavin and Jimbo.

title: Inventing a Capitalist Region: Upper Silesia/Poland - Economic Transformations in Old-Industrial and Post-Socialist Spaces of Central and Eastern Europe
Creators: name: Weis, Christian
Publisher: name: The Open University
Year: 2007

description: The thesis explores economic, political and social processes in former socialist countries with a case study in one of the biggest conurbations in Europe, Upper Silesia. The ongoing but selective economic processes of global and macro-regional economic integration have been identified as a main issue in geographical research. In particular the nexus between the global and the local seen as a dialectical relationship, composed of multiple and asymmetric interdependencies has stressed the necessity of utilising relational analysis in economic geography. The question emerges in what ways and to what extent increasing economic integration may lead to a socio-economic convergence of places or the development of 'indigenous capacities', spatial peculiarities and legacies to establish themselves in capitalist networks of production. With empirical reference to the Polish conurbation of Upper Silesia and drawing on the analytical framework from Michael Storper's 'Holy Trinity' ("The Regional World", New York, 1997), this thesis analyses post socialist urban and regional transformations from three angles. 1. While Storper analysed mainly 'successful' regions in the West, the research tries to identify the main challenges that face any simple attempt to adapt western (theoretical) approaches within a post-socialist, Central East European context. 2. The thesis then identifies the fabric of political economic actors and the path dependent 'invention' of a region, here Upper Silesia, and analysis locally and regionally embedded and recombined informal institutions and their capacity for restructuring of an old industrial space. 3. While inter- and intra-regional competition is growing in an 'era of globalisation', the thesis finally investigates the scope for action and 'reflexive' interrelations between administrative, political and economic actors in an 'ordinary region' prior to the accession to the European Union.
Study of Z Pair Production and Anomalous Couplings in e+e- Collisions at sqrt(s) between 190 GeV and 209 GeV

description: A study of Z-boson pair production in e+e- annihilation at center-of-mass energies between 190 GeV and 209 GeV is reported. Final states containing only leptons, (l+l-l+l- and l+l-nn), quark and lepton pairs, (qql+l-, qqnn) and only hadrons (qqqq) are considered. In all states with at least one Z boson decaying hadronically, lifetime, lepton and event-shape tags are used to separate bb pairs from qq final state. Limits on anomalous ZZgamma and ZZZ couplings are derived from the measured cross sections and from event kinematics using an optimal observable method. Limits on low scale gravity with large dimensions are derived from the cross sections and their dependence on polar angle.

Pulsed RF Schemes for Tearing Mode Stabilization

description: The RF stabilization of tearing modes with current condensation has the potential to increase stabilization efficiency and loosen power localization requirements. Such benefits stem from the cooperative feedback between the RF deposition and resulting island temperature perturbation governed by diffusion. A self consistent treatment of the damping of an rf ray as it traverses the island shows that low damping scenarios can require unfavorably high powers to overcome initial power leakage and effectively capitalize on the nonlinear effect. In this work it is demonstrated that for such regimes,modulated stabilization schemes can achieve significant improvements in heating and current drive contributions to stabilization for the same average power as a continuous wave scheme. The impact of modulation frequency and duty cycle on the performance is explored, the results of which suggest modulation strategies in which the pulsing periods are kept on the order of a diffusive time.
Black hole mass function and its evolution -- the first prediction for the Einstein Telescope

description: The knowledge about the black hole mass function (BHMF) and its evolution would help to understand the origin of the BHs and how BH binaries formed at different stages of the history of the Universe. We demonstrate the ability of future third generation gravitational wave (GW) detector -- the Einstein Telescope (ET) to infer the slope of the BHMF and its evolution with redshift. We perform the Monte Carlo simulation of the measurements of chirp signals from binary BH systems (BBH) that could be detected by ET, including the BH masses and their luminosity distances ($d_L$). We use the mass of a primary black hole in each binary system to infer the BHMF as a power-law function with slope parameter as $α$. Taking into account the bias that could be introduced by the uncertainty of measurements and by the selection effect, we carried out the numerical tests and find that only one thousand of GW events registered by ET ($\sim1\%$ amount of its yearly detection rate) could accurately infer the $α$ with a precision of $α\sim0.1$. Furthermore, we investigate the validity of our method to recover a scenario where $α$ evolves with redshift as $α(z) = α_0 + α_1\frac{z}{1+z}$. Taking a thousand of GW events and using $d_L$ as the redshift estimator, our tests show that one could infer the value of evolving parameter $α_1$ accurately with the uncertainty level of $\sim0.5$. Our numerical tests verify the reliability of our method. The uncertainty levels of the inferred parameters can be trusted directly for the several sets of the parameter we assumed, yet shouldn't be treated as a universal level for the general case.

description: The International Court of Justice (ICJ) advisory opinion on 22 July 2010, affirmed the legality of the Republic of Kosovo’s declaration of independence. Yet it is an unspoken truth that Kosovo needs a compromise with Serbia to receive international recognition. Turkey can contribute to bridging relations between Belgrade and Pristina by identifying ways of cooperation on technical issues concerning the living standards of all Kosovar citizens without getting entangled on the issue of recognition. Turkey can play a complimentary and even crucial role that could actually ease the task of the European Union between Serbia and Kosovo.

description: Bosnia-Herzegovina remains as divided as ever. In the past year Turkish foreign policy in Bosnia-Herzegovina has become more assertive and outcome-oriented. The successes of the new Turkish assertiveness have helped to initiate a much- needed reconciliation process between Serbia and Bosnia-Herzegovina. Turkey derives its assertiveness not only from Foreign Minister Davutoğlu’s vision of sustainable peace but also from its shared history and cultural practices throughout the region. Turkey’s efforts could strengthen the efforts of the international community to integrate BiH into European and trans-Atlantic bodies.

description: We provide a geometric characterization of manifolds of dimension 3 with fundamental groups of which all conjugacy classes except 1 are infinite, namely of which the von Neumann algebras are factors of type $II_1$: they are essentially the 3-manifolds with infinite fundamental groups on which there does not exist any Seifert fibration. Otherwise said and more precisely, let $M$ be a compact connected 3-manifold and let $Γ$ be its fundamental group, supposed to be infinite and with at least one finite conjugacy class besides 1. If $M$ is orientable, then $Γ$ is the fundamental group of a Seifert manifold; if $M$ is not orientable, then $Γ$ is the fundamental group of a Seifert manifold modulo $\Bbb P$ in the sense of Heil and Whitten \cite{HeWh--94}. We make heavy use of results on 3-manifolds, as well classical results (as can be found in the books of Hempel, Jaco, and Shalen), as more recent ones (solution of the Seifert fibred space conjecture).
