The comparative advantage of the public sector in the development of urban water supply

This paper addresses the potential of public water operations in achieving developmental goals such as the Millennium Development Goals, and argues that the public sector has a comparative advantage in developing water services. The global importance of the public sector in urban water supply is examined through a review of current practice in the world's largest cities, including operational presence and distribution and ongoing trends. Empirical evidence shows that, in transition and developing countries, public operators are capable of undergoing successful reform. One explanatory factor is proposed to be the creation through the public sphere of highly interconnected networks among stakeholders. Such accountability networks act as vehicles for the generation and distribution of public knowledge among stakeholders, which in turn inform rational decision making on the reform and management of operations.

Synthesis of Piano Stool Complexes Employing the Pentafluorophenyl Substituted Diphosphine (C6F5)2PCH2P(C6F5)2 and the Effect of Phosphine Modifiers on Hydrogen Transfer Catalysis.

Ruthenium, rhodium, and iridium piano stool complexes of the pentafluorophenyl-substituted diphosphine (C6F5)2PCH2P(C6F5)2 (2) have been prepared and structurally characterized by single-crystal X-ray diffraction. The Cp-P tethered complex [{(C5Me4CH2C6F4(C6F5)CH2P(C6F5)2}RhCl2] (9), in which only one phosphorus is coordinated to the rhodium, was prepared by thermolysis of a slurry of [Cp*RhCl(-Cl)]2 and 2 and was structurally characterized by single-crystal X-ray diffraction. The tethering occurs by intramolecular dehydrofluorinative coupling of the pentamethylcyclopentadienyl ligand and P,P-coordinated 2. The geometric changes that occur on tethering force dissociation of one of the phosphorus atoms. The effects of introducing phosphine ligands to the coordination sphere of piano stool hydrogen transfer catalysts have been studied. The complexes of fluorinated phosphine complexes are found to transfer hydrogen at rates that compare favorably with leading catalysts, particularly when the phosphine and cyclopentadienyl functionalities are tethered. The highly chelating Cp-PP complex [(C5Me4CH2-2-C5F3N-4-PPhCH2CH2PPh2)RhCl]BF4 (1) was found to outperform all other complexes tested. The mechanism of hydrogen transfer catalyzed by piano stool phosphine complexes is discussed with reference to the trends in activity observed.

Geometry in preduals of spaces of 2-homogeneous polynomials on Hilbert spaces

Let H be a (real or complex) Hilbert space. Using spectral theory and properties of the Schatten–Von Neumann operators, we prove that every symmetric tensor of unit norm in HoH is an infinite absolute convex combination of points of the form xox with x in the unit sphere of the Hilbert space. We use this to obtain explicit characterizations of the smooth points of the unit ball of HoH .

The unit ball of the complex P(3H)

Let H be a two-dimensional complex Hilbert space and P(3H) the space of 3-homogeneous polynomials on H. We give a characterization of the extreme points of its unit ball, P(3H), from which we deduce that the unit sphere of P(3H) is the disjoint union of the sets of its extreme and smooth points. We also show that an extreme point of P(3H) remains extreme as considered as an element of L(3H). Finally we make a few remarks about the geometry of the unit ball of the predual of P(3H) and give a characterization of its smooth points.

Research on Ultimate Loading Carrying Capacities in Concrete Bridge Deck Slabs with Consideration of Compressive Membrane Action

In the investigation of real loading capacities in concrete bridge deck slabs,the study of this type of structure was carried out with consideration of compressive membrane action.A series of experimental test of steel-concrete bridge structures was developed with the analysis of influences from the varying of structural parameters on loading capacities,including reinforcement percentages,supporting beam sizes and concrete compressive strength.Through the study of the experimental results,it was found that the real structural loading capacities are larger than those predicted by current design methods.Therefore,based on the previous research,a prediction method for loading capacities of concrete bridge deck slabs was established with consideration of CMA,which was built based on the plastic ultimate analysis.In this method,the lateral restraint stiffness subjected by concrete bridge deck slabs was provided.The proposed theoretical model is capable of predicting the loading capacities of this type of structure accurately with comparison of results from several bridge deck experimental tests.

The persistence of the HgCl2 molecule in five new compounds in the system (NH4)(w)HgxCly(H2O)(z) with w : x : y : z=1 : 5 : 11 : 0, 2 : 3 : 8 : 1, 4 : 3 : 10 : 2, 2 : 1 : 4 : 1, and 10 : 3 : 16 : 0

Five new compounds in the system (NH4)Cl/HgCl2/H2O have been obtained as colourless single crystals, (NH4)Hg5Cl11, (NH4)(2)Hg3Cl8(H2O), (NH4)(4)Hg3Cl10(H2O)(2), (NH4)(2)HgCl4(H2O), and (NH4)(10)Hg3Cl16. In all of these, as in HgCl2 itself, (almost) linear HgCl2 molecules persist with Hg-Cl distances varying from 229 to 236 pm. In (NH4)(10)Hg3Cl16 there are also tetrahedra [HgCl4] with d(Hg-Cl) = 247 pm present. If larger Hg-Cl distances (of up to 340 pm) are considered as belonging to the coordination sphere of Hg-II, the structures may be described as consisting of isolated octahedra and tetrahedra as in (NH4)(10)Hg3Cl16, edge-connected chains as in (NH4)(2)HgCl4(H2O), edge-connected chains and layers of octahedra as in (NH4)(4)Hg3Cl10(H2O)(2), corrugated layers of edge-connected octahedra as in (NH4)(2)Hg3Cl8(H2O), and, finally, a three-dimensional network of connected six- and seven-coordinate Hg-Cl polyhedra as in (NH4)Hg5Cl11. The water molecules are never attached to Hg-II. The (NH4)(+) cations, and sometimes Cl- anions, play a role for electroneutrality only.

The anonymity of the hunt: A critique of hunting as sharing

Hunter-gatherers are often ascribed a “monistic” worldview at odds with the nature-society dichotomy. The centerpiece of this claim is that they view hunting as similar to sharing within the band and prey animals as part of a common sphere of sociality. This article challenges this thesis. An examination of the work of its main proponents shows that it conflates two different senses of “animal”—the flesh-and-blood animals of the hunt and the animal Spirit that is said to control the animals. The sharing motif in hunting makes sense with respect to the anthropomorphic Spirit but not to the animals hunted. The conditions of the hunt as a spatiotemporal event provide further grounds for skepticism toward the idea of hunting-as-sharing. Drawing on biologist Robert Hinde’s model of relationships, I argue that hunting represents an anonymous one-off interaction that cannot develop into a personal relationship, in stark contrast to the durable forms of personalized sociality associated with the hunter-gatherer band. This is not to deny the possibility of human-animal cosociality in the form of personal relationships but rather to redirect the search away from the hunt to the interface with domesticated animals.

The Library of Essays on Law and Privacy

Privacy has now become a major topic not only in law but in computing, psychology, economics and social studies, and the explosion in scholarship has made it difficult for the student to traverse the field and identify the significant issues across the many disciplines. This series brings together a collection of significant papers with a multi-disciplinary approach which enable the reader to navigate through the complexities of the issues and make sense of the prolific scholarship published in this field.

The three volumes in this series address different themes: an anthropological approach to what privacy means in a cultural context; the issue of state surveillance where the state must both protect the individual and protect others from that individual and also protect itself; and, finally, what privacy might mean in a world where government and commerce collect data incessantly. The regulation of privacy is continually being called for and these papers help enable understanding of the ethical rationales behind the choices made in the sphere of regulation of privacy.

The articles presented in each of these collections have been chosen for the quality of their scholarship and their utility to the researcher, and feature a variety of approaches. The articles which debate the technical context of privacy are accessible to those from the arts and humanities; overall, the breadth of approach taken in the choice of articles has created a series which is an invaluable and important resource for lecturers, researchers and student.

Kierkegaard : the temporality of becoming a self

Introduction In Difference and Repetition, Deleuze compares and contrasts Kierkegaard's and Nietzsche's ideas of repetition. He argues that neither of them really give a representation of repetition. Repetition for them is a sort of selective task: the way in which they determine what is ethical and eternal. With Nietzsche, it is a theater of un belie f. ..... Nietzsche's leading idea is to found the repetition in the etemal return at once on the death of God and the dissolution of the self But it is a quite different alliance in the theater of faith: Kierkegaard dreams of alliance between a God and a self rediscovered. I Repetition plays a theatrical role in their thinking. It allows them to dramatically stage the interplay of various personnae. Deleuze does give a positive account ofKierkegaard's "repetition"; however, he does not think that Kierkegaard works out a philosophical model, or a representation of what repetition is. It is true that in the book Repetition, Constantin Constantius does not clearly and fully work out the concept of repetition, but in Sickness Unto Death, Kierkegaard gives a full explanation of the self and its temporality which can be connected with repetition. When Sickness Unto Death is interpreted according to key passages from Repetition and The Concept of Anxiety, a clear philosophical concept of repetition can be established. In my opinion, Kierkegaard's philosophy is about the task of becoming a self, and I will be attempting to show that he does have a model of the temporality of self-becoming. In Sickness Unto Death, Kierkegaard explains his notions of despair with reference to sin, self, self-becoming, faith, and repetition. Despair is a sickness of the spirit, of the self, and accordingly can take three forms: in despair not to be conscious of having a self (not despair in the strict sense); in despair not to will to be oneself; in despair to will to be oneself2 In relation to this definition, he defines a self as "a relation that relates itself to itself and in relating itself to itself relates to another.''3 Thus, a person is a threefold relationship, and any break in that relationship is despair. Despair takes three forms corresponding to the three aspects of a self s relation to itself Kierkegaard says that a selfis like a house with a basement, a first floor, and a second floor.4 This model of the house, and the concept of the stages on life's way that it illustrates, is central to Kierkegaard's philosophy. This thesis will show how he unpacks this model in many of his writings with different concepts being developed in different texts. His method is to work with the same model in different ways throughout his authorship. He assigns many of the texts to different pseudonyms, but in this thesis we will treat the model and the related concepts as being Kierkegaard's and not only the pseudonyms. This is justified as our thesis will show this modelremains the same throughout Kierkegaard's work, though it is treated in different ways by different pseudonyms. According to Kierkegaard, many people live in only the basement for their entire lives, that is, as aesthetes ("in despair not to be conscious of having a self'). They live in despair of not being conscious of having a self They live in a merely horizontal relation. They want to get what they desire. When they go to the first floor, so to speak, they reflect on themselves and only then do they begin to get a self In this stage, one acquires an ideology of the required and overcomes the strict commands of the desired. The ethical is primarily an obedience to the required whereas the aesthetic is an obedience to desire. In his work Fear and Trembling (Copenhagen: 1843), Johannes de Silentio makes several observations concerning this point. In this book, the author several times allows the desired ideality of esthetics to be shipwrecked on the required ideality of ethics, in order through these collisions to bring to light the religious ideality as the ideality that precisely is the ideality of actuality, and therefore just as desirable as that of esthetics and not as impossible as the ideality of ethics. This is accomplished in such a way that the religious ideality breaks forth in the dialectical leap and in the positive mood - "Behold all things have become new" as well as in the negative mood that is the passion of the absurd to which the concept "repetition" corresponds.s Here one begins to become responsible because one seeks the required ideality; however, the required ideality and the desired ideality become inadequate to the ethical individual. Neither of them satisfy him ("in despair not to will to be oneself'). Then he moves up to the second floor: that is, the mystical region, or the sphere of religiousness (A) ("despair to will to be oneself). Kiericegaard's model of a house, which is connected with the above definition ofdespair, shows us how the self arises through these various stages, and shows the stages of despair as well. On the second floor, we become mystics, or Knights of Infinite Resignation. We are still in despair because we despair ofthe basement and the first floor, however, we can be fiill, free persons only ifwe live on all the floors at the same time. This is a sort of paradoxical fourth stage consisting of all three floors; this is the sphere of true religiousness (religiousness (B)). It is distinguished from religiousness (A) because we can go back and live on all the floors. It is not that there are four floors, but in the fourth stage, we live paradoxically on three at once. Kierkegaard uses this house analogy in order to explain how we become a self through these stages, and to show the various stages of despair. Consequently, I will be explaining self-becoming in relation to despair. It will also be necessary to explain it in relation to faith, for faith is precisely the overcoming of despair. After explaining the becoming of the self in relation to despair and faith, I will then explain its temporality and thereby its repetition. What Kierkegaard calls a formula, Deleuze calls a representation. Unfortunately, Deleuze does not acknowledge Kierkegaard's formula for repetition. As we shall see, Kierkegaard clearly gives a formula for despair, faith, and selfbecoming. When viewed properly, these formulae yield a formula for repetition because when one hasfaith, the basement, firstfloor, and secondfloor become new as one becomes oneself The self is not bound in the eternity ofthe first floor (ethical) or the temporality of the basement (aesthete). I shall now examine the two forms of conscious despair in such a way as to point out also a rise in the consciousness of the nature of despair and in the consciousness that one's state is despair, or, what amounts to the same thing and is the salient point, a rise in the consciousness of the self The opposite to being in despair is to have faith. Therefore, the formula set forth above, which describes a state in which there is not despair at all, is entirely correct, and this formula is also the formula for faMi in ^elating itself to itself and in willing to be itself, the self rests transparently in the power that established it.

The new woman, femininity and modernity in Margery Allingham's detective novels of the 1930s /

This thesis examines Death of a Ghost (1934), Flowers for the Judge (1935), Dancers in Mourning (1937), and The Fashion in Shrouds (1938), a group of detective novels by Margery Allingham that are differentiated from her other work by their generic hybridity. The thesis argues that the hybrid nature of this group of Campion novels enabled a highly skilled and insightful writer such as Allingham to negotiate the contradictory notions about the place of women that characterized the 1930s, and that in dOing so, she revealed the potential of one of the most popular and accessible genres, the detective novel of manners, to engage its readers in a serious cultural dialogue. The thesis also suggests that there is a connection between Allingham's exploration of modernity and femininity within these four novels and her personal circumstances. This argument is predicated upon the assumption that during the interwar period in England several social and cultural attitudes converged to challenge long-held beliefs about gender roles and class structure; that the real impact of this convergence was felt during the 1930s by the generation that had come of age in the previous decade-Margery Allingham's generation; and that that generation's ambivalence and confusion were reflected in the popular fiction of the decade. These attitudes were those of twentieth-century modernity--contradiction, discontinuity, fragmentation, contingency-and in the context of this study they are incorporated in a literary hybrid. Allingham uses this combination of the classical detective story and the novel of manners to examine the notion of femininity by juxtaposing the narrative of a longstanding patriarchal and hierarchical culture, embodied in the image of the Angel in the House, with that of the relatively recent rights and freedoms represented by the New Woman of the late nineteenth-century. Pierre Bourdieu's theory of social difference forms the theoretical foundation of the thesis's argument that through these conflicting narratives, as well as through the lives of her female characters, Allingham questioned the Hsocial myth" of the time, a prevailing view that, since the First World War, attitudes toward the appropriate role and sphere of women had changed.

Between the spheres : male characters and the performance of femininity in four victorian novels, 1849-1886

“Between the Spheres: Male Characters and the Performance of Femininity in Four Victorian Novels, 1849-1886” définit le célibataire domestique, analyse les effets de l’érosion des frontières entre les domaines public et privé et retrace l’évolution du discours public au sujet de la masculinité dans quatre œuvres: Shirley écrit par Charlotte Brontë, Lady Audley’s Secret de Mary Elizabeth Braddon, Daniel Deronda par George Eliot, et The Strange Case of Dr. Jekyll and Mr. Hyde de Robert Louis Stevenson. En identifiant le célibataire domestique comme personnage récurrent à la dernière moitié du dixneuvième siècle, cette dissertation démontre comment ce personnage arrive à représenter l’incertitude face aux questions de sexualité, non seulement dans des rôles féminins mais aussi dans les positions de l’homme dans la société et la remise en question du concept de la masculinité. Tout comme il y eu de femmes à l’affût de la liberté au-delà du domaine privé, des hommes aussi cherchèrent leur liberté au sein du domaine domestique par des performances féminines. Le célibataire domestique rapporte sur le concept New Woman de cette période par sa tendance de promouvoir de nouvelles définitions de la masculinité victorienne et les limites entre sexes. Le célibataire domestique passe du domaine public, plutôt masculin, vers le domaine privé, plutôt féminin en participitant dans le discours féminin, tel que les sujets de le domesticité, la chastité, la moralité, le mariage, et l’amour. En s’inspirant de l’analyse des domaines public et privé par Jürgen Habermas, cette dissertation revoit les rôles de ces domaines et leur élasticité dans les quatre œuvres en question ainsi que le sort des célibataires domestiques. L’assignation de sexe à ces domaines mena à la recherche de nouveaux formes de masculinité, produisant une définition de mâle liée au statut de la femme dans le domaine privé. Le célibataire domestique se déplace facilement entre ces domaines sans souffrir d’accusations de tendances effeminées ou d’aliénation sociale, à l’encontre des conséquences qu’ont souffert les personnages femelles pour leur comportement inhabituel. Chaque chapitre de cette dissertation considère les changements dans le discours de la sexualité afin de suivre la migration du célibataire domestique du domaine féminin au milieu du dixneuvième siècle jusqu’un nouveau domaine à la fin de siècle qui estompe la distinction rigide crue être en place tout au long de la période victorienne.

Activism and participation among people of migrant background : discourses and practices of inclusiveness in four italian cities

Alors que l’intérêt pour les processus d’intégration des immigrants et des minorités ethniques est en pleine croissance parmi les chercheurs européens, les facteurs qui expliquent les différentes formes de participation civique et politique doivent être examinés plus en profondeur. Prenant pour base la littérature sur l’immigration, cette étude examine la question de recherche suivante: Comment peut-on expliquer les variations des formes de participation civique et politique des activistes issus de l’immigration au niveau local? Afin de répondre à cette question, cette étude identifie les formes de participation de la part d’activistes issus de l’immigration dans quatre villes Italiennes et examine les discours et les pratiques de multiples acteurs impliqués dans le domaine de l’immigration dans un contexte national d’hostilité croissante. Cette thèse soutient que pour comprendre différentes formes de participation, il est important de considérer non seulement l’État et les acteurs institutionnels, mais aussi les acteurs non-institutionnels et examiner comment ces derniers influencent les opportunités ainsi que les restrictions à la participation. Par ailleurs, cette recherche examine les canaux conventionnels et non-conventionnels dans quatre villes italiennes et étudie les activistes issus de l’immigration comme des acteurs politiques pertinents, capables de se mobiliser et d’influencer la participation à travers leur interaction et alliances avec les acteurs de la société d’accueil. Cette recherche a permis de produire trois résultats. Le premier montre que les approches d’intégration adoptées par les acteurs sont importantes. Cette étude a identifié trois approches d’intégration: 1) « welfariste », basée sur l’idée que les immigrants sont dans le besoin et doivent donc recevoir des services; 2) interculturelle, basée sur l’idée que les immigrants sont de futurs citoyens et que l’intégration est réciproque; 3) promotion des droits politiques, basée sur l’idée que les immigrants ont des droits politiques fondamentaux ; et qui encourage l’ouverture des canaux de participation politique, surtout aux immigrants privés du droit de vote local. L’analyse empirique démontre que, alors que l’approche welfariste n’encourage pas la participation parce qu’elle conçoit les immigrants comme des acteurs passifs, les autres deux approches ont respectivement un impact sur les formes de participation civique et politique. La deuxième conclusion souligne le rôle des acteurs de gauche. En particulier, cette étude montre que les acteurs qui ouvrent de canaux pour la participation ne sont pas uniquement les acteurs de gauche modérée, comme les autorités locales, les partis politiques et les syndicats, mais aussi les groupes de gauche radicale et non-institutionnelle. Chaque acteur de gauche comprend et agit différemment par rapport aux sujets de l’immigration et de la participation et ce fait influence comment les activistes issues de l’immigration se mobilisent. La troisième conclusion met en évidence le rôle de la perception des opportunités par les activistes issus de l’immigration et la façon avec laquelle ils s’approprient les discours et les pratiques des acteurs de gauche. Ce travail démontre que l’ouverture de canaux est possible grâce à l’engagement de personnes issues de l’immigration qui agissent à travers les opportunités qui leurs sont offertes, créent des alliances avec la gauche et défient les discours et pratiques des acteurs locaux.

Synthesis and Characterisation of New Transition Metal Complexes of Schiff Bases Derived from 3-hydroxyquinoxaline-2- carboxaldehyde and Application of Some ofthese Complexes as Hydrogenation and Oxidation Catalysts

The thesis deals with studies on the synthesis, characterisation and catalytic applications of some new transition metal complexes of the Schiff bases derived from 3-hydroxyquinoxaline 2-carboxaldehyde.. Schiff bases which are considered as ‘privileged ligands’ have the ability to stabilize different metals in different oxidation states and thus regulate the performance of metals in a large variety of catalytic transformations. The catalytic activity of the Schiff base complexes is highly dependant on the environment about the metal center and their conformational flexibility. Therefore it is to be expected that the introduction of bulky substituents near the coordination sites might lead to low symmetry complexes with enhanced catalytic properties. With this view new transition metal complexes of Schiff bases derived from 3-hydroxyquinoxaline-2-carboxaldehyde have been synthesised. These Schiff bases have more basic donor nitrogen atoms and the presence of the quinoxaline ring may be presumed to build a favourable topography and electronic environment in the immediate coordination sphere of the metal. The aldehyde was condensed with amines 1,8-diaminonaphthalene, 2,3-diaminomaleonitrile, 1,2-diaminocyclohexane, 2-aminophenol and 4-aminoantipyrine to give the respective Schiff bases. The oxovanadium(IV), copper(II) and ruthenium(II)complexes of these Schiff bases were synthesised and characterised. All the oxovanadium(IV) complexes have binuclear structure with a square pyramidal geometry. Ruthenium and copper form mononuclear complexes with the Schiff base derived from 4- aminoantipyrine while binuclear square planar complexes are formed with the other Schiff bases. The catalytic activity of the copper complexes was evaluated in the hydroxylation of phenol with hydrogen peroxide as oxidant. Catechol and hydroquinone are the major products. Catalytic properties of the oxovanadium(IV) complexes were evaluated in the oxidation of cyclohexene with hydrogen peroxide as the oxidant. Here allylic oxidation products rather than epoxides are formed as the major products. The ruthenium(II) complexes are found to be effective catalysts for the hydrogenation of benzene and toluene. The kinetics of hydrogenation was studied and a suitable mechanism has been proposed.

Criminal justice system in pondicherry - a comparative critical study of the past and the presen

The Union Territory of Pondicherry prior to its merger with the Indian Union was a French Colony. The erstwhile territory of Pondicherry along with its hamlets, namely, KARAIKKAL, MAHE and YANAM was administered by the French Regime. Before it was established by French in 1 6 74 A.D. it was part of Vijayanagara Empire. Prior to this, Pondicherry was a part of the Kingdom of Chola and Pallava Kings. During French Regime, the laws which were in force in France in relation to administration of civil and criminal justice were extended to the erstwhile Territory of Pondicherry. Thus while Pondicherry stood influenced by the Inquisitorial system since the beginning of the 18th century, the neighboring states forming part of the Indian Union since Independence came under the Influence of the British system, viz. accusatorial system. The territory of Pondicherry, for administrative reasons, came to be merged with the Indian Union in the early 60's. Following the merger, the Indian administration sought to extent its own laws from time to time replacing erstwhile French Laws, however, subject to certain savings. Thus the transitional period witnessed consequential changes in the administration of the territory, including the sphere of judicial system. Since I 963, the Union Territory of Pondicherry was brought under the spell of the Indian Legal System The people in Pondicherry ' thus have had the benefit of experiencing both the svstems. Their experiences will be of much help to those who undertake comparative studies in law. The plus and minus points of the respective systems help one to develop a detachment that helps independent evaluation of the svstents. The result of these studies could be relevant in revitalising our criminal systems.The present system is evaluated in the light of the past system. New dimensions are added by way' of an empirical study also.
