description: Im Rahmen des von der DFG geförderten Sonderforschungsbereichs 69 („Geowissenschaftliche Probleme in ariden und semi-ariden Gebieten", TU Berlin) wurden in Nordsomalia Geländeuntersuchungen zum quartären Klima- und Landschaftswandel durchgeführt. Das gegenwärtig aride bis semiaride Klima hatte offenbar feuchtere Vorläuferphasen, die aber nach den bisherigen Erkenntnissen nicht so gravierende Oszillationen kannten wie in der Sahara. Sie dokumentieren sich u. a. in reliktischen Böden, in Karstphänomenen, in fluvialen Terrassen und in mehreren Epochen menschlicher Besiedlung. Am auffälligsten bieten sich unterschiedliche Arten nichtmariner Kalkablagerungen wie Tuffe, Travertine und Sinter dar. Fünf Typen sind repräsentiert: (1) Breite Talauen sind kilometerweit von bis zu 4 m mächtigen Travertindecken überzogen, die eine jungpleistozäne Sequenz fluvialer, pedogener und lakustriner Sedimente abschließen. — (2) An Berghängen treten bis zu 30 m hohe und 300 m breite Quelltuffe auf. — (3) Bis zu 40 m hohe Sinterbarrieren haben manche ehemaligen Flußläufe abgedämmt. — (4) Sekundäre Kalkdecken, bis 2 m mächtig, überziehen zahlreiche Berghänge. — (5) Höhlensinter werden vor allem aus dem westlichen Teil Nordsomalias beschrieben, sie scheinen aber im Untersuchungsgebiet selten zu sein. Geomorphologische, archäologische und Isotopen-Datierungen zeigen unterschiedliche Perioden verstärkter Kalkausfällung im Laufe des Quartärs. Ein auf etwa 18.000 B. P. datierter limnischer Horizont enthält zahlreiche Invertebraten-Fossilien sowie jungpaläolithische Artefakte. Andere 14C-Datierungen belegen, daß die großen präislamischen Gräberfelder sowie die Steinplätze (= Feuerstellen von Nomaden) offenbar aus protohistorischer bis historischer Zeit stammen. Sie geben Hinweise auf höhere Bevölkerungsdichten während der letzten zwei Jahrtausende.

description: Coherence is a fundamental notion in quantum mechanics, defined relative to a reference basis. As such, it does not necessarily reveal the locality of interactions nor takes into account the accessible operations in a composite quantum system. In this paper, we put forward a notion of localizable coherence as the coherence that can be stored in a particular subsystem, either by measuring or just by disregarding the rest. We examine its spreading, its average properties in the Hilbert space and show that it can be applied to reveal the real-space structure of states of interest in quantum many-body theory, for example, localized or topological states.

Geowissenschaftliche Bedeutung von Mikrorissen in Kristallingesteinen

Year: 2006

description: In Kristallingesteinen (Magmatite, Metamorphite, Migmatite) sind Mikrorisse allgegenwärtig. Ihre Entstehung ist auf unterschiedliche treibende Kräfte (i.W. Tektonik, Thermik) und Mechanismen wie z.B. volumetrische Verformung oder plastische Rissinitiierung zurückzuführen (z.B. Vollbrecht et al. 1999). Die heute in oberflächennahen Kristallingesteinen zu beobachtenden Mikrorisspopulationen repräsentieren i.d.R. die Summe verschiedener geologischer Ereignisse in unterschiedlichen Krustenstockwerken, wobei generell die jüngsten Generationen das höchste Erhaltungspotential besitzen. Abhängig von den jeweiligen stofflichen Rahmenbedingungen (Wirtsminerale, Krustenfluide) zeigen die Mikrorisse unterschiedliche Ausbildungsformen (offen, verheilt, versiegelt), die häufig gemeinsam in einem Gestein auftreten und damit komplexe, mehrphasige Entwicklungen dokumentieren. Analysen von natürlichen und experimentell erzeugten Rissen belegen, dass die überwiegende Anzahl als Zugrisse zu interpretieren sind, d.h. sie werden primär senkrecht zur kleinsten Normalspannung angelegt. Zusätzlich ist bekannt, dass Mikrorisse innerhalb größerer Gesteinsvolumina meistens in Form von mehreren richtungskonstanten Scharen auftreten und damit den Gesteinen ein Anisotropieelement aufprägen. Das Beispiel zeigt zusätzlich, dass die Bildung der verheilten und offenen Mikrorisse unter verschiedenen Spannungsrichtungen stattfand. Aufgrund der genannten Eigenschaften besitzen Mikrorisse sowohl für die Rekonstruktion geodynamischer Entwicklungen als auch für die Interpretation der physikalischen/mechanischen Gesteinseigenschaften besondere Bedeutung. Das Vernetzungsschema zeigt, welche Informationen aus Mikrorissen durch Verknüpfung verschiedener analytischer Methoden gewonnen werden können...

description: Martensitic transformations are strain driven displacive transitions governing the mechanical and physical properties in intermetallic materials. This is the case in Ni$_2$MnGa, where the martensite transition is at the heart of the striking magnetic shape memory and magneto-caloric properties. Interestingly, the martensitic transformation is preceded by a pre-martensite phase, and the role of this precursor and its influence on the martensitic transition and properties is still a matter of debate. In this work, we report on the influence of Co doping (Ni$_{50-x}$Co$_x$Mn$_{25}$Ga$_{25}$ with x = 3 and 5) on the martensitic transformation path in stoichiometric Ni$_2$MnGa by neutron diffraction. The use of the superspace formalism to describe the crystal structure of the modulated martensitic phases, joined with a group theoretical analysis allows unfolding the different distortions featuring the structural transitions. Finally, a general Landau thermodynamic potential of the martensitic transformation, based on the symmetry analysis is outlined. The combined use of phenomenological and crystallographic studies highlights the close relationship between the lattice distortions at the core of the Ni$_2$MnGa physical properties and, more in general, on the properties of the martensitic transformations in the Ni-Mn based Heusler systems.

description: The suevitic Onaping Formation overlies the layered Main Mass of the 1.85Ga Sudbury Igneous Complex (SIC) of the Sudbury Impact Structure, Ontario. The Formation consists of four Members, namely from top to bottom, the Black, the Green, the Gray and the Basal. Post-impact NWSE shortening during the Penokean Orogeny (ca. 1.9–1.75 Ga) affected the Onaping Formation and led to the lobate shape of the SIC in plan view. In order to investigate the possible fold origin of the NE-lobe of the SIC, a field-based structural analysis of the Onaping Formation was conducted in the Frenchman Lake area. The analysis is based on structural measurements at 580 stations and encompasses the orientation of mineral shape fabrics as well as their intensity. In addition to these quantities, lithological variation and metamorphic overprint of the Onaping Formation was examined. Special attention was paid thereby to the Green Member since previous workers stated that it forms a continuous unit at the base of the Black Member...

description: By imposing the boundary condition associated with the boundary structure of the null boundaries rather than the usual one, we find that the key requirement in Harlow-Wu's algorithm fails to be met in the whole covariant phase space. Instead, it can be satisfied in its submanifold with the null boundaries given by the expansion free and shear free hypersurfaces in Einstein's gravity, which can be regarded as the origin of the non-triviality of null boundaries in terms of Wald-Zoupas's prescription. But nevertheless, by sticking to the variational principle as our guiding principle and adapting Harlow-Wu's algorithm to the aforementioned submanifold, we successfully reproduce the Hamiltonians obtained previously by Wald-Zoupas' prescription, where not only are we endowed with the expansion free and shear free null boundary as the natural stand point for the definition of the Hamiltonian in the whole covariant phase space, but also led naturally to the correct boundary term for such a definition.

description: Non commutative superspaces can be introduced as the Moyal-Weyl quantization of a Poisson bracket for classical superfields. Different deformations are studied corresponding to constant background fields in string theory. Supersymmetric and non supersymmetric deformations can be defined, depending on the differential operators used to define the Poisson bracket. Some examples of deformed, 4 dimensional lagrangians are given. For extended superspace (N>1), some new deformations can be defined, with no analogue in the N=1 case.

Publisher: name: American University
Year: 2023

description: The Great Dismal Swamp of Virginia and North Carolina was once home to many seeking refuge from colonial system, histories that remain hidden or forgotten within today's view of the swamp. The resistance communities that found refuge within the boundaries of the swamp include Disenfranchised Native Americans, African Maroons, and any others seeking a life free of colonial influence. The Great Dismal Swamp Landscape Study (GDSLS) was formed in order to archaeologically explore these resistance communities in terms of their diasporan and exilic characteristics and make known their marginalized pasts. The project employs a predictive model of community structure labeled the Modes of Communitization, which includes the Semi-Independent Mode, the Scission Mode and the Labor Exploitation Mode. This exposition explores the Scission Mode (interior) and archaeologically tests whether or not those communities formed on the north plateau of the nameless site display traits associated with interior community formation.

description: Multiple myeloma is a blood cancer for which few therapies exist, most of which are limited by toxicity and tumor resistance. Fatty acid synthase, an enzyme which catalyzes the conversion of carbohydrate to fatty acids, is highly expressed in multiple myeloma, among other cancers. This research investigated the potential of orlistat, a fatty acid synthase inhibitor, as a multiple myeloma therapeutic in vitro. In vitro, orlistat reduced proliferation of multiple myeloma cells, induced apoptosis, slowed progression through the cell cycle, and altered expression of survival and mitotic genes.

Gender differences in attitudes towards credit, terms of trade, and the household balance sheet
Creators: name: Routzahn, Julie Lyn
Publisher: name: American University
Year: 2023

description: Changes in lending and financial innovations in the last 20 years increased access to debt. Consumers embraced the conveniences of debt, and social changes encouraged debt use. As a result, household debt grew considerably. Little is known about how these changes in the availability of debt affected women's finances. It does seem that bankruptcy rates grew, particularly for women, with women accounting for 30% of all bankruptcy filings in 1997 (Sullivan and Warren 1999). No previous research focuses on understanding differences in household debt by gender. We do not know if women prefer different relative amounts of debt, if they use different types of lending arrangements, and if they choose different balance sheet ratios relative to men. The objective of this dissertation is to determine the extent to which gender differences in attitudes towards credit, and gender differences in the terms of borrowing can explain gender differences in household balance sheets. To accomplish the objectives, I use the 2007 Survey of Consumer Finances (SCF). When I compare never married women to all respondents, never married women are more accepting of most kinds of debt. This is consistent with conceptions of women as spendthrifts but not consistent with the conservative attitudes towards investment by women. However, when I look more specifically at gender by limiting the analysis to just never married women and never married men, there are no detectible gender differences in attitudes towards the use of credit.When I compare never married women to all respondents, never married women pay higher interest rates on credit card debt. However, when I look specifically at gender by limiting the sample to never married women and never married men, there are no detectable gender differences in interest rate loan costs. Finally, I show that despite their greater acceptance to borrow, never married females tend to have stronger balance sheet ratios than married/cohabitating households. Despite no differences in attitudes towards credit, never married women have weaker household balance sheets than never married men, indicating that never married women are borrowing more, relative to their available resources.

description: Fast radio bursts are bright, millisecond-scale radio flashes of yet unknown physical origin. Recently, their extragalactic nature has been demonstrated and an increasing number of the sources have been found to repeat. Young, highly magnetized, isolated neutron stars - magnetars - have been suggested as the most promising candidates for fast radio burst progenitors owing to their energetics and high X-ray flaring activity. Here we report the detection with the Konus-Wind of a hard X-ray event of April 28, 2020, temporarily coincident with a bright, two-peak radio burst from the Galactic magnetar SGR~1935+2154 with properties remarkably similar to those of fast radio bursts. We show that two peaks of the double-peaked X-ray burst coincide in time with the radio peaks, confirming that the X-ray and radio emission most likely have a common origin. Thus, this is the first simultaneous detection of a fast radio burst from a Galactic magnetar and its high-energy counterpart. The total energy emitted in X-rays in this burst is typical of bright short magnetar bursts, but an unusual hardness of its energy spectrum strongly distinguish the April 28 event among multiple "ordinary" flares detected from SGR~1935+2154 previously. This, and a recent non-detection of radio emission from about one hundred typical soft bursts from SGR 1935+2154 favors the idea that bright, FRB-like magnetar signals are associated with rare, hard-spectrum X-ray bursts, which implied rate ($\sim$ 0.04 yr$^{-1}$ magnetar$^{-1}$) appears consistent with the rate estimate of SGR 1935+2154-like radio bursts (0.007 - 0.04 yr$^{-1}$ magnetar$^{-1}$).

description: We present an RI photometric survey covering an area of 430 arcmin^2 around the multiple star Sigma Orionis. The observations were conducted with the 0.8 m IAC-80 Telescope at the Teide Observatory. The survey limiting R and I magnitudes are 22.5 and 21, and completeness magnitudes 21 and 20, respectively. We have selected 53 candidates from the I vs. R-I colour-magnitude diagram (I=14-20) that follow the previously known photometric sequence of the cluster. Adopting an age of 2-4 Myr for the cluster, we find that these objects span a mass range from 0.35 Msol to 0.015 Msol. We have performed J-band photometry of 52 candidates and Ks photometry for 12 of them, with the result that 50 follow the expected infrared sequence for the cluster, thus confirming with great confidence that the majority of the candidates are bona fide members. JHKs photometry from the Two Micron All Sky Survey (2MASS) is available for 50 of the candidates and are in good agreement with our data. Out of 48 candidates, which have photometric accuracies better than 0.1 mag in all bands, only three appear to show near-infrared excesses.

description: The spin-1 ferromagnetic Blume-Capel film with an alternating crystal field $Δ=Δ_1$ on the odd layers and $Δ=Δ_2$ on the even ones is considered in the mean field approximation. The ground state phase diagrams in the ($d_1,d_2$) plane ($d_1=Δ_1/J$ and $d_2=Δ_2/J$) are determined analytically; the number of their phases depends on the parity of the number of layers of the film. At finite temperature, fifteen types of topology, depending on the range of variation of $d_1$, are found in the (t,$d_2$) plane for an even number of layers, but only fourteen for an odd number of layers. The phase diagrams exhibit a variety of multicritical points. In particular, a tricritical point C appears in the paramagnetic-ferromagnetic line of transition, but only for values of $d_1$ larger than a threshold value $d_{trc}^{(2)} ={8 \ln 2 \over 3}$ which is but the tricritical crystal field (in the mean field approximation) of the spin-1 Blume-Capel model on a square lattice. Moreover, lines of transition presenting the reentrant and double reentrant behaviors may also take place.

Drei Löss-Paläobodenabfolgen werden beschrieben, die im nördlichen Vorgebirge des Alborz (Profile Neka und Now Deh) und im Lösshügelland nördlich Gondbad-e Kavus (Profil Agh Band) aufgeschlossen sind. Das Profil Neka besteht aus feinkörnigem Löss, der von zwei kräftig entwickelten Paläobodenkomplexen aus Bwk-, Bt- und AhBt-Horizonten durchzogen wird. Erste Lumineszenzdatierungen weisen darauf hin, dass der obere Pedokomplex während der Sauerstoff-Isotopen-Stadien (OIS) 5a und/oder 5c gebildet wurde, während der untere das OIS 5e oder ein älteres Interglazial repräsentieren könnte. Neun hell braune oder dunkel braune bis rötlich-braune Paläoböden (CBk-, Bwk- und Bt-Horizonte) des Lösses bei Now Deh spiegeln unterschiedliche Verwitterungsintensitäten von Interglazialen und Interstadialen des Mittleren bis Oberen Pleistozäns wider. Während der obere Bt-Horizont von Now Deh wahrscheinlich mit dem OIS 5e korreliert, bilden die unteren Bt-Horizonte einen Pedokomplex, der das Interglazial des OIS 7 repräsentiert. Die Pedo-komplexe in Neka und Now Deh weisen jeweils auf polyzyklische Bodenentwicklung hin, die Bodenbildung, Bodenabtrag, Lössaufwehung und erneute Bodenbildung umfasste. In den Lösshügeln bei Agh Band bedeckt ein 40 m mächtiges, weitgehend homogenes, gipshaltiges und feinsand- sowie grobschluffreiches Lösspaket einen braunen Paläoböden (Bw(t)), der vermutlich in das letzte Interglazial zu stellen ist. Die beschriebenen Löss-Paläobodenabfolgen dokumentieren den mehrfachen Wechsel von trocken-kalten zu feucht-warmen Klimaverhältnissen mit Lössablagerung bzw. Bodenbildung. Sie stellen ausgezeichnete terrestrische Archive des quartären Klima- und Umweltwandels Nordirans dar.

Argentineans in Spain : immigrants or returnees? Institutional versus popular interpretations
Creators: name: Vives Gonzalez, Celia
Publisher: name: University of British Columbia
Year: 2011

description: Since 1985, the phenomenon of immigration in Spain has emerged as a social concern, a keystone in national politics, and a topic in need of further research. This thesis aims to build on the existing work by exploring how two processes, the growth and increasing diversity of the immigrant population in Spain and the Europeanization of the country's immigration law, have impacted the legal integration of the Latin American immigrant community since the mid 1980s. Focusing on the case of Argentinean immigrants, I use a variety of methods to discuss the profile and evolution of this community in the context of the broader general and Latin American immigrations in Spain. This includes an analysis of the changes in immigration and citizenship legislation since 1985, paying special attention to those that have impacted Argentinean immigrants; an exploration of the representation of Argentineans in popular discourse; and a discussion of the ways in which these immigrants see themselves as insiders / outsiders within the Spanish nation-state. I conclude that there are two conflicting interpretations of Argentinean immigration in Spain. The first and most prevalent is the representation of the Argentinean immigrant as a returnee. This representation emerges strongly in popular discourse, immigrants' claims of belonging to the nation-state, and citizenship legislation; it is a legacy of both Spanish colonialism and emigration of Spaniards to Argentina in the past. The second is the representation of the Argentinean as an economic immigrant, which emerged in the 2000 immigration law. Argentineans are trapped in the contradictions and tensions between these two representations, but far from being passive recipients of the definitions and categories that the state imposes on them, there is evidence that they organize, accept, resist, or manipulate public discourses in their search to find a place for themselves in Spanish society. This thesis supports the status of public policy on immigration and citizenship as a boundary-marker for the national community, and calls for a greater attention to non-governmental actors in the institutionalization of immigration as an object of such public policy.

description: 3C 454.3 is frequently observed in flaring state. The long term light curve of this source has been analysed with 9 year (August 2008 - July 2017) data from Fermi LAT detector. We have identified five flares and one quiescent state. The flares have sub-structures with many peaks during flaring phase. We have estimated the rise and decay time of the flares and compared with flares of other similar sources. The modeling of gamma ray spectral energy distributions shows in most cases Log parabola function gives the best fit to the data. We have done time dependent leptonic modeling of two of the flares, for which simultaneous multi-wavelength data are available. These two long lasting flares Flare-2A and Flare-2D continued for 95 days and 133 days respectively. We have used the average values of Doppler factor, injected luminosity in electrons, size of the emission region and the magnetic field in the emission region in modeling these flares. The emission region is assumed to be in the broad line region in our single zone model. The energy losses (synchrotron, synchrotron self-Compton, external Compton) and escape of electrons from the emission region have been included while doing the modelling. Although, the total jet powers required to model these flares with leptonic model are higher compared to other sources, they are always found to be lower than the Eddington's luminosity of 3C 454.3. We also select some flaring peaks and show that time variation of the Doppler factor or the injected luminosity in electrons over short time scales can explain their light curves.

description: During Pinochet's Dictatorship in Chile, Osvaldo sneaks into a The Astrum Aureum Society, a secret group of adepts of the occult. As he learns the magic secrets, he begins to question the alleged wisdom, and also realizes that the immense network of the society is its real super power. Osvaldo is forced to keep the charade until he makes it to become the Great Master of the whole organization. However, when he achieves the ultimate leadership of the society, he is already completely skeptical about the secret arcana, and convinced of the iniquity of the Astrum Aureum Society. Therefore he writes a memoir on a copybook: the copybook of the Great Master.
Theory of spin-polarized superconductors -- an analogue of superfluid $^3$He A-phase

description: It is shown theoretically that ferromagnetic superconductors, UGe$_2$, URhGe, and UCoGe can be described in terms of the A-phase like triplet pairing similar to superfluid $^3$He in a unified way, including peculiar reentrant, S-shape, or L-shape $H_{\rm c2}$ curves. The associated double transition inevitable between the A$_1$ and A$_2$-phases in the $H$-$T$ plane is predicted, both of which are characterized by non-unitary state with broken time reversal symmetry and the half-gap. UTe$_2$, which has been discovered quite recently to be a spin-polarized superconductor, is analyzed successively in the same view point, pointing out that the expected A$_1$-A$_2$ transition is indeed emerging experimentally. Thus the four heavy Fermion compounds all together are entitled to be topologically rich solid state materials worth further investigating together with superfluid $^3$He A-phase.

description: PSR J0205+6449 is a young pulsar in the Crab-like pulsar wind nebula 3C 58 which is thought to be a result of the historical supernova SN1181 CE. The 65.7-ms pulsar is the second most energetic of the known Galactic pulsars and has been shown to be remarkably cool for its age, implying non-standard cooling processes in the neutron star core. We report on RXTE timing observations taken during AO7 and supplemented by monthly radio observations of the pulsar made with the Green Bank Telescope (GBT). The total duration covered with the timing solutions is 450 days. We measure very high levels of timing noise from the source and find evidence for a ``giant'' glitch of magnitude Delta nu/nu ~ 1x10^-6 that occurred in 2002 October. We have also measured the phase-resolved spectra of the pulsations and find them to be surprisingly hard, with photon indices Gamma = 0.84 +0.06/-0.15 for the main pulse and Gamma = 1.0 +0.4/-0.3 for the interpulse assuming an absorbed power-law model.

Disc fragmentation and oligarchic growth of protostellar systems in low-metallicity gas clouds

description: We study low-metallicity star formation with a set of high-resolution hydrodynamics simulations for various gas metallicities over a wide range $0$--$10^{-3} \ {\rm Z}_{\bigodot}$. Our simulations follow non-equilibrium chemistry and radiative cooling by adopting realistic elemental abundance and dust size distribution. We examine the condition for the fragmentation of collapsing clouds (cloud fragmentation; CF) and of accretion discs (disc fragmentation; DF). We find that CF is suppressed due to rapid gas heating accompanied with molecular hydrogen formation even with efficient dust cooling for metallicities $\gtrsim 10^{-5} \ {\rm Z}_{\bigodot}$. Instead, DF occurs in almost all runs regardless of metallicity. We also find that, in the accretion discs, the growth of the protostellar systems is overall oligarchic. The primary protostar grows through the accretion of gas, and secondary protostars form through the interaction of spiral arms or the break-up of a rapidly rotating protostar. Despite vigorous fragmentation, a large fraction of secondary protostars are destroyed through mergers or tidal disruption events. For a few hundred years after the first adiabatic core formation, only several protostars survive in the disc, and the total mass of protostars is $0.52$--$3.8 \ {\rm M}_{\bigodot}$.

Robust "trapping states" in the motion of a trapped ion

description: A novel robust mechanism for the generation of "trapping states" is shown to exist in the coupling of a two-level system with an oscillator, which is based on nonlinearities in the laser-induced vibronic coupling. This mechanism is exemplified with an ion confined in the potential well of a trap, where the nonlinearities are due to Franck--Condon type overlap integrals of the laser waves with the ionic centre-of-mass wavefunction. In contrast to the coherent trapping mechanism known from micro-maser theory, this mechanism works also in an incoherent regime operated by noisy lasers and is therefore much more robust against external decoherence effects. These features favour the incoherent regime, in particular for the preparation of highly excited trapping states.

Inconvenient Justice: The Struggle to "Close the Books" in Afghanistan and Nepal
Creators: name: Sajjad, Tazreena
Publisher: name: American University
Year: 2023

description: Inconvenient Justice argues for a more nuanced understanding of the dynamic "local" that goes beyond the realm of a cultural framework. Correspondingly, it suggests that conceptualization of the "local" needs to be problematized further to expose the tensions and hierarchies of and within the local, and to question whose version of the local is actually prioritized in transitional justice programming. Specifically it asserts that the local must be understood as an inter-subjective concept and that the "local" in transitional justice should be seen as a dynamic, evolving phenomenon. This research examines five specific areas, which it insists, are critical components defining the local: (i) the historical context within which "transitional justice" mechanisms are implemented; (ii) the limitations of, and opportunities for, local legal systems to engage with transitional justice questions; (iii) the internal/domestic and international politicking around the "transitional justice" discourse; iv) the importance of centrally placing the local to define justice; and, (v) as an illustration of the domestic struggle for long-term justice, the role of National Human Rights Institutions (NHRIs) which link local voices to national and international platforms of decision-making and balance their role of advocating for human rights, while looking into past instances of abuses. Using a comparative case study approach, this research draws on one hundred and fifteen in-depth interviews conducted with international and national organizations, policy-makers, government officials, journalists, experts, and victims' groups in Kabul, Kathmandu, Washington D.C., and New York. It also incorporates participant observation, narrative research and analyses of reports, correspondence, press releases, agreements, bills, official texts, newspaper articles and petitions to provide an in-depth understanding of the complexities of the justice question in both these contexts.
