Sultan, Caliph, and the Renewer of the Faith - Mauro Nobili - Bog - Cambridge University Press - Plusbog.dk

Sultan, Caliph, and the Renewer of the Faith - Mauro Nobili - Bog - Cambridge University Press - Plusbog.dk

The Tārīkh al-fattāsh is one of the most important and celebrated sources for the history of pre-colonial West Africa, yet it has confounded scholars for decades with its inconsistences and questions surrounding its authorship. In this study, Mauro Nobili examines and challenges existing theories on the chronicle, arguing that much of what we have presumed about the work is deeply flawed. Making extensive use of previously unpublished Arabic sources, Nobili demonstrates that the Tārīkh al-fattāsh was in fact written in the nineteenth century by a Fulani scholar, Nūḥ b. al-Ṭāhir, who modified pre-existing historiographical material as a political project in legitimation of the West African Islamic state known as the Caliphate of Ḥamdallāhi and its founding leader Aḥmad Lobbo. Contextualizing its production within the broader development of the religious and political landscape of West Africa, this study represents a significant moment in the study of West African history and of the evolution of Arabic historical literature in Timbuktu and its surrounding regions.

Etisk resiliens - Carl F. Kähler - Bog - Frydenlund - Plusbog.dk

Etisk resiliens - Carl F. Kähler - Bog - Frydenlund - Plusbog.dk

Med udgangspunkt i en række voksne skilsmissebørns beretninger om deres oplevelser af følgerne af forældrenes skilsmisse undersøger Carl F. Kähler i sin nye bog den etiske karakterstyrkes betydning for børnenes måde at komme igennem krisen på.En skilsmisse opleves ofte som et tillidsbrud af børnene, der kan få svært ved at finde tilbage til værdier som forpligtelse og tillid. En skilsmisse kan betyde, at børnene ikke får konsolideret deres mentale modeller af det, der er rigtigt og forkert, men må leve med en usikkerhed i de nære relationer.Resiliens betegner generelt en positiv personlig udvikling, hvor især unge bliver i stand til at indhente deres jævnaldrende og gennemføre de livsmål, der karakteriserer det liv, den uddannelse og karriere, de vælger på trods af meget vanskelige opvækstvilkår.I bogen bruges cases fra skilsmissebørn, der har formået at bruge værdibaseret viljestyrke til at overvinde den modstand, de har været udsat for. Etisk resiliens forudsætter, at barnet eller den unge forstår, at der er en årsagssammenhæng mellem det, det gør, og det, der sker, også når det undlader at gøre noget. Den etiske resiliens er forudsætningen for, at individet kan opfylde sine formål og ændre på de punkter, der strider imod dets ideelle mål.Den etiske resiliens er i modsætning til offermentalitet en forudsætning for den modenhed, der kan følge af at komme bedre igennem vanskelige opvækstvilkår end forventet.Bogen Etisk resiliens – en undersøgelse af den etiske karakterstyrke henvender sig til psykologer, socialrådgivere, socialpædagoger og andre, der møder børn og unge, der har oplevet svære opvækstvilkår.Carl F. Kähler er mag.art. i litteraturvidenskab fra Københavns Universitet med sidefag i psykologi, filosofi og oldtidskundskab. Han har undervist i mange år, bl.a. på Københavns Universitet, Folkeuniversitetet og i gymnasiet. Han er desuden forfatter til flere bøger og har bidraget med artikler om såvel psykologiske som filosofiske emner i både danske og udenlandske tidsskrifter.

Lectures on Kahler Groups - Professor Pierre Py - Bog - Princeton University Press - Plusbog.dk

Lectures on Kahler Groups - Professor Pierre Py - Bog - Princeton University Press - Plusbog.dk

An introduction to the state-of-the-art in the study of Kähler groups This book gives an authoritative and up-to-date introduction to the study of fundamental groups of compact Kähler manifolds, known as Kähler groups. Approaching the subject from the perspective of a geometric group theorist, Pierre Py equips readers with the necessary background in both geometric group theory and Kähler geometry, covering topics such as the actions of Kähler groups on spaces of nonpositive curvature, the large-scale geometry of infinite covering spaces of compact Kähler manifolds, and the topology of level sets of pluriharmonic functions.Presenting the most important results from the past three decades, the book provides graduate students and researchers with detailed original proofs of several central theorems, including Gromov and Schoen’s description of Kähler group actions on trees; the study of solvable quotients of Kähler groups following the works of Arapura, Beauville, Campana, Delzant, and Nori; and Napier and Ramachandran’s work characterizing covering spaces of compact Kähler manifolds having many ends. It also describes without proof many of the recent breakthroughs in the field. Lectures on Kähler Groups also gives, in eight appendixes, detailed introductions to such topics as the study of ends of groups and spaces, groups acting on trees and Hilbert spaces, potential theory, and L 2 cohomology on Riemannian manifolds.

Den kropsmindede hjerne - Carl F. Kähler - Bog - Frydenlund - Plusbog.dk

Den kropsmindede hjerne - Carl F. Kähler - Bog - Frydenlund - Plusbog.dk

"Den kropsmindede hjerne - Antonio Damasios teori om den emotive subjektivitet ".Antonio Damasio og hans forskning i følelser, selvet og bevidstheden er blevet mere og mere populær. Bogen her indkredser Damasios betydning for forskningen. Antonio Damasio beskæftiger sig med relationen mellem menneskets emotioner, følelser og intellekt, og disses rod i hjernen og biologien. Han hævder f.eks., at vores emotioner i høj grad – såvel negativt som positivt og oftest ubevidst – spiller ind i beslutningsprocesser, som vi ellers betragter som rationelle.Med påvisningen af sammenhængen mellem følelserne og de neurale processer har Damasio lanceret begrebet den kropsmindede hjerne, som har givet titel til – og som bliver grundigt belyst og perspektiveret i – denne bog.Damasios synspunkt er, at alle områder af kroppen konstant signalerer til hjernen, og at disse områder af kroppen så at sige portrætteres i bestemte områder i hjernen i form af neurale kort, der hele tiden ændrer sig.Emotioner er således i Damasios terminologi kropstilstande, mens følelser er bevidsthedstilstande. Kroppen og hjernen er så nært forbundne af biokemiske og neurale kredsløb, at man ikke kan tale om en psyko-fysisk dualisme, sådan som man ellers har gjort historisk set. Bogen henvender sig til psykologer, lærere, pædagoger og studerende inden for disse områder samt alle andre, der ønsker at vide mere om udviklingen af hjernen og selvet. Carl F. Kähler er mag.art. i litteraturvidenskab fra Københavns Universitet med sidefag i psykologi, filosofi og oldtidskundskab.

Det kompetente selv - Carl F. Kähler - Bog - Frydenlund - Plusbog.dk

Det kompetente selv - Carl F. Kähler - Bog - Frydenlund - Plusbog.dk

Bogen er en introduktion til Banduras hovedværk fra 1997: 'Self-Efficacy: The Exercise of Control' samt til hans teorier om den personlige kompetences betydning for menneskers måde at klare sig på i det moderne samfund.Den canadisk-amerikanske psykologiprofessor Albert Bandura (født 1925) anses i dag for en af hovedkræfterne bag den kognitive revolution, der prægede psykologien i slutningen af 1960'erne, og som satte fokus på menneskets selverkendelse og sociale indlæring.Vores motivation og handlinger i forskellige situationer afhænger af, om vi tror på vores egne evner i den givne kontekst. Det kan altså være svært at mestre en opgave, selv om vi har evnerne, hvis vi ikke tror på os selv og på egne evner. Bandura beskriver den menneskelige adfærd og de bagvedliggende kognitive processer mere dækkende end hans forgængere. Han giver forklaringen på, hvorfor vi agerer, som vi gør, og han kommer ydermere med anvisninger på, hvordan vi kan forstå os selv bedre, arbejde med og udvikle os selv.Bogen henvender sig til alle, der vil vide mere om Bandura og hans tanker, herunder særligt psykologer og alle der arbejder med personaleudvikling og HR. Carl F. Kähler er mag.art. i litteraturvidenskab med sidefag i psykologi, filosofi og oldtidskundskab. Han har undervist i mange år, bl.a. på Københavns Universitet, Folkeuniversitetet og i gymnasiet.

The Hidden History of Women's Ordination - Gary (p John Nobili Macy - Bog - Oxford University Press Inc - Plusbog.dk

The Hidden History of Women's Ordination - Gary (p John Nobili Macy - Bog - Oxford University Press Inc - Plusbog.dk

The Roman Catholic leadership still refuses to ordain women officially or even to recognize that women are capable of ordination. But is the widely held assumption that women have always been excluded from such roles historically accurate? How might the current debate change if our view of the history of women''s ordination were to change? In The Hidden History of Women''s Ordination, Gary Macy offers illuminating and surprising answers to these questions. Macy argues that for the first twelve hundred years of Christianity, women were in fact ordained into various roles in the church. He uncovers references to the ordination of women in papal, episcopal and theological documents of the time, and the rites for these ordinations have survived. The insistence among scholars that women were not ordained, Macy shows, is based on a later definition of ordination, one that would have been unknown in the early Middle Ages. In the early centuries of Christianity, ordination was understood as the process and the ceremony by which one moved to any new ministry in the community. In the early Middle Ages, women served in at least four central ministries: episcopa (woman bishop), presbytera (woman priest), deaconess and abbess. The ordinations of women continued until the Gregorian reforms of the eleventh and twelfth centuries radically altered the definition of ordination. These reforms not only removed women from the ordained ministry, but also attempted to eradicate any memory of women''s ordination in the past. With profound implications for how women are viewed in Christian history, and for current debates about the role of women in the church, The Hidden History of Women''s Ordination offers new answers to an old question and overturns a long-held erroneous belief.

Test Configurations, Stabilities and Canonical Kahler Metrics - Toshiki Mabuchi - Bog - Springer Verlag, Singapore - Plusbog.dk

Test Configurations, Stabilities and Canonical Kahler Metrics - Toshiki Mabuchi - Bog - Springer Verlag, Singapore - Plusbog.dk

The Yau-Tian-Donaldson conjecture for anti-canonical polarization was recently solved affirmatively by Chen-Donaldson-Sun and Tian. However, this conjecture is still open for general polarizations or more generally in extremal Kähler cases. In this book, the unsolved cases of the conjecture will be discussed. It will be shown that the problem is closely related to the geometry of moduli spaces of test configurations for polarized algebraic manifolds. Another important tool in our approach is the Chow norm introduced by Zhang. This is closely related to Ding''s functional, and plays a crucial role in our differential geometric study of stability. By discussing the Chow norm from various points of view, we shall make a systematic study of the existence problem of extremal Kähler metrics.

Kys livet – også når det gør ondt - Margrethe Kähler - Bog - Ældre Sagen - Plusbog.dk

Kys livet – også når det gør ondt - Margrethe Kähler - Bog - Ældre Sagen - Plusbog.dk

Kys Livet – også når det gør ondt tager udgangspunkt i seks kvinder og syv mænds fortællinger. Bogens personer repræsenterer forskellige livsformer, humør og sind – og forskellige meninger og holdninger. Men fælles for dem er, at de har noget på hjerte, og at de har viljen til at løse de udfordringer og problemer, de står overfor. Bogen går tæt tilværelsens fundamentale udfordringer. Nogle udfordringer har med selve livsfasen at gøre; at stoppe på arbejdsmarkedet; at børn flytter hjemmefra; at være fanget i et krydspres mellem arbejdsliv, gamle forældre og børnebørn, der skal passes. Andre går på tværs af livsfaserne: Skilsmisse, ægtefælles død, ensomhed, konflikter i familien, singleliv, erotik, forhold til venner. Til sidst sammenfattes det almene i de personlige fortællinger: De fælles tanker, følelser og synspunkter hos bogens personer. Udgiver : Ældre Sagen

N=2 Wonderland, The: From Calabi-yau Manifolds To Topological Field Theories - Paolo Soriani - Bog - World Scientific Publishing Co Pte Ltd -

This book presents, in a unifying perspective, the topics related to N =2 supersymmetry in two dimensions. Beginning with the Kähler structure of D =4 supergravity Lagrangians, through the analysis of string compactifications on Calabi-Yau manifolds, one reaches the heart of the matter with the chiral ring structure of N =2 conformal field theories and its relation to topological field theory models and Landau–Ginzburg models. In addition, mirror symmetry, topological twists and Picard–Fuchs equations are discussed.

Variational Problems in Differential Geometry - - Bog - Cambridge University Press - Plusbog.dk

The field of geometric variational problems is fast-moving and influential. These problems interact with many other areas of mathematics and have strong relevance to the study of integrable systems, mathematical physics and PDEs. The workshop ''Variational Problems in Differential Geometry'' held in 2009 at the University of Leeds brought together internationally respected researchers from many different areas of the field. Topics discussed included recent developments in harmonic maps and morphisms, minimal and CMC surfaces, extremal Kähler metrics, the Yamabe functional, Hamiltonian variational problems and topics related to gauge theory and to the Ricci flow. These articles reflect the whole spectrum of the subject and cover not only current results, but also the varied methods and techniques used in attacking variational problems. With a mix of original and expository papers, this volume forms a valuable reference for more experienced researchers and an ideal introduction for graduate students and postdoctoral researchers.

Differential Geometry - Clifford Henry Taubes - Bog - Oxford University Press - Plusbog.dk

Bundles, connections, metrics and curvature are the ''lingua franca'' of modern differential geometry and theoretical physics. This book will supply a graduate student in mathematics or theoretical physics with the fundamentals of these objects. Many of the tools used in differential topology are introduced and the basic results about differentiable manifolds, smooth maps, differential forms, vector fields, Lie groups, and Grassmanians are all presented here. Other material covered includes the basic theorems about geodesics and Jacobi fields, the classification theorem for flat connections, the definition of characteristic classes, and also an introduction to complex and Kähler geometry.Differential Geometry uses many of the classical examples from, and applications of, the subjects it covers, in particular those where closed form expressions are available, to bring abstract ideas to life. Helpfully, proofs are offered for almost all assertions throughout. All of the introductory material is presented in full and this is the only such source with the classical examples presented in detail.

Algebraic Models in Geometry - John Oprea - Bog - Oxford University Press - Plusbog.dk

Algebraic Models in Geometry - John Oprea - Bog - Oxford University Press - Plusbog.dk

Rational homotopy is a very powerful tool for differential topology and geometry. This text aims to provide graduates and researchers with the tools necessary for the use of rational homotopy in geometry. Algebraic Models in Geometry has been written for topologists who are drawn to geometrical problems amenable to topological methods and also for geometers who are faced with problems requiring topological approaches and thus need a simple and concrete introduction to rational homotopy. This is essentially a book of applications. Geodesics, curvature, embeddings of manifolds, blow-ups, complex and Kähler manifolds, symplectic geometry, torus actions, configurations and arrangements are all covered. The chapters related to these subjects act as an introduction to the topic, a survey, and a guide to the literature. But no matter what the particular subject is, the central theme of the book persists; namely, there is a beautiful connection between geometry and rational homotopy which both serves to solve geometric problems and spur the development of topological methods.
