description: Although the \emph{residual method}, or \emph{constrained regularization}, is frequently used in applications, a detailed study of its properties is still missing. This sharply contrasts the progress of the theory of Tikhonov regularization, where a series of new results for regularization in Banach spaces has been published in the recent years. The present paper intends to bridge the gap between the existing theories as far as possible. We develop a stability and convergence theory for the residual method in general topological spaces. In addition, we prove convergence rates in terms of (generalized) Bregman distances, which can also be applied to non-convex regularization functionals. We provide three examples that show the applicability of our theory. The first example is the regularized solution of linear operator equations on $L^p$-spaces, where we show that the results of Tikhonov regularization generalize unchanged to the residual method. As a second example, we consider the problem of density estimation from a finite number of sampling points, using the Wasserstein distance as a fidelity term and an entropy measure as regularization term. It is shown that the densities obtained in this way depend continuously on the location of the sampled points and that the underlying density can be recovered as the number of sampling points tends to infinity. Finally, we apply our theory to compressed sensing. Here, we show the well-posedness of the method and derive convergence rates both for convex and non-convex regularization under rather weak conditions.

Clinical Implications of Cultural Differences in Factors Influencing Resilience Following Natural Disaster: A Systematic Review
Creators: name: Anbarasu, SC
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Health psychology

description: Natural disasters such as hurricanes, tsunamis, floods and earthquakes not only damage and destroy the land, sea, forest and other resources vital to peoples’ livelihoods but also impact the lives of the victims in an adverse way: physically, mentally, emotionally and economically. In the immediate aftermath of disasters, unaffected individuals and organisations often feel compelled to help in whatever capacity may be available to them - including the provision of psychosocial interventions. However, there are also risks involved with providing psychosocial interventions including unintentional harm due to “disaster tourism” or “parachuting”. It is not uncommon for those providing psychosocial interventions to violate cultural and social norms in ways that negatively impact the recovery process, and potentially impede resilient outcomes. Hence, the aim of the review was to identify and describe the psychological consequences, the types of interventions as well as resilience and coping skills of survivors of natural disasters, namely earthquakes, hurricane, tsunami and flood across different cultures. Twelve studies were identified for this review and PTSD was the most common psychological consequence identified. Even though there were some differences in resilience and coping strategies of natural disaster survivors, on a microenvironmental level, social support appeared to be common. On a macro-systemic level, community factors, such as community services, cultural factors, spirituality and religion contributed to resilience across several cultures. However, psychological interventions adopted varied across different cultures. In addition to understanding the culture, spiritual, and beliefs of the disaster survivors, the importance of working with appropriate community operations and adopting culturally sensitive screening instruments in the future cannot be overlooked.

description: We construct a canonical Green current T_f for every quasi-algebraically stable meromorphic self-map f of CP^k such that its first dynamical degree λ_1(f) is a simple root of its characteristic polynomial and that λ_1(f) > 1. We establish a functional equation for T_f and show that the support of T_f is contained in the Julia set of f, which is thus non empty.

Predictors of Resilience in First-Year University Students
Creators: name: House, JE
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Educational psychology

description: Recent research focussed on student adaptation to university has shown that resilience is an important attribute for students. As such, this study aimed to identify the concurrent demographic, intrapersonal and interpersonal factors predicting resilience in first year university students. A further aim was to investigate whether there were differences in the experience of full-time versus part-time students in resilience. Participants were 420 students enrolled in a variety of courses at the University of Tasmania, who completed questionnaires measuring resilience and predictors thereof. The hypothesis that higher levels of personal growth initiative, optimism and social adjustment would predict higher levels of resilience was supported. Psychological distress negatively predicted resilience. Contrary to expectations, attachment to university and social support were not found to positively predict resilience. Part-time students reported higher levels of resilience, personal growth initiative and optimism, as well as lower levels of psychological distress compared to full-time students. No differences were found between part-time and full-time students in social adjustment. It was concluded that resilience in first year university students encompasses intrapersonal, interpersonal and demographic factors.

description: We report on Landauer-Büttiker studies of anomalous Hall transport in a two-dimensional electron gas with Rashba spin-orbit coupling and a magnetization provided by localized magnetic moments. Our system is described by a discretized tight-binding model in a four-terminal geometry. We consider both the case of magnetically disordered systems as well as ballistic transport in disorder-free systems with spatially homoge- neous magnetization. In the latter case we investigate both out-of-plane and in-plane magnetizations. We numerically establish a close connection between singularities in the density of states and peaks in the Hall conductance close to the lower band edge. Consistent with previous theoretical studies based on diagrammatic perturbation expansions, these peaks occur at Fermi energies where only the lower dispersion branch is occupied. Moreover, for large magnetization the Hall conductance is, along with the density of states, sup- pressed. This numerical finding can be understood from analytical properties of the underlying model in the limit of an infinite system.

description: An understanding of the behavior of SARS-CoV-2 in pediatric hematology-oncology patients is essential to the optimal management of these patients during the COVID-19 pandemic. This study describes the characteristics and outcomes of COVID-19 disease in children with cancer or hematologic disorders treated at a large children’s hospital. A retrospective cohort study was conducted at Texas Children’s Cancer and Hematology Center from January 1, 2020 to September 30, 2020. All patients with a primary hematology-oncology diagnosis and SARS-CoV-2 positivity by reverse transcription polymerase chain reaction were identified. Clinical and laboratory data were obtained from the medical record. Descriptive analyses were performed to evaluate COVID-19-related outcomes and risk factors for severe disease in this population. We identified 109 patients with COVID-19 disease, including 52 hematology, 51 oncology, and 6 HSCT patients; median age was 10.3 years (IQR 4.4–15.9), and 58.7% were male. Seventy-four percent of the patients were managed in the outpatient setting. Patients with sickle cell disease were more likely to require hospitalization. ICU care was needed in 8% (n = 9) of the entire cohort, and mechanical ventilation was required in 6.4% (6 oncology patients, 1 hematology patient). COVID-19 contributed to the deaths of two cancer patients. No deaths occurred in hematology or HSCT patients. In conclusion, the risk of severe COVID-19 complications is slightly higher in pediatric hematology-oncology patients than in the general pediatric population but lower than initially feared. For most asymptomatic patients, primary disease management may continue as planned, but treatment decisions must be individualized.
A study of the albumen quality of shell eggs
Creators: name: Eissinger, Ronald Carl
Publisher: name: University of British Columbia
Year: 2011

description: Eggs from twelve strains of layers in the Ninth British Columbia Random Sample Egg Laying Test were examined over an eight month period to determine rate of decline of interior egg quality under three varying temperature conditions for one and two week periods. Differences among strains in the initial egg quality by period as well as the quality decline under different storage conditions were examined. Consideration was also given to the implications these results may have on sample size determinations in a quality control program or interior egg quality assessment investigations. Highly significant differences were found among strains and treatments in average Haugh unit score for each of the eight periods. Differences were also found in rate of decline of interior egg quality among strains and treatments for most periods. Sample size estimates calculated from the data obtained along with the variations found among strains, treatments and periods suggest that our present sampling methods for quality control programs and interior egg quality assessment studies may need to be re-valuated.

description: High grade gliomas (HGG) have a dismal prognosis with survival rates of 15–35%. Approximately 10–12% of pediatric HGG occur in young children and their molecular biology and clinical outcomes differ from those arising at older ages. We report on four children aged <5 years newly diagnosed with non-brainstem HGG between 2011 and 2018 who were treated with surgery and BBSFOP chemotherapy. Two died of tumor progression. The other two are still alive without radiotherapy at 3.8 and 3.9 years from diagnosis: one of whom remains disease-free off treatment; and the other one, whose tumor harbored a KCTD16:NTRK2 fusion, went on to receive larotrectinib. Additionally we review the general management, outcomes and latest updates in molecular biology and targeted therapies for young children with HGG. Infant gliomas can be stratified in molecular subgroups with clinically actionable oncogenic drivers. Chemotherapy-based strategies can avoid or delay the need for radiotherapy in young children with HGG. Harnessing the potential of NTRK, ALK, ROS1 and MET inhibitors offers the opportunity to optimize the therapeutic armamentarium to improve current outcomes for these children.
title: Struggling for Reconstruction, Houses, Homes and “the State” after the Earthquake in Muzaffarabad, Azad Kashmir
Creators: name: Schild, Pascale
Publisher: name: National Institute of Pakistan Studies
Year: 2014

description: In this paper I think of the 2005 earthquake in Pakistan and Azad Kashmir as an “empirical window” on society providing insights into “common” rather than “exceptional” social processes, practices and power relations. With reference to my ethnographic fieldwork in Muzaffarabad, the capital of Azad Kashmir, I deal with local actors’ perspectives and practices related to the destruction and reconstruction of houses and homes in the earthquake’s aftermath. As an emic category of social practice in society “home” (ghar) refers to flexible arrangements of people, places, things and values, which are closely related to structures and processes of the larger society and the state. Rather than presenting final results, the paper points to some initial analysis of material, social and political processes of house and home examining how social actors re-construct and re-negotiate houses and homes in daily life and thereby struggle over values and resources visà-vis state reconstruction policies and activities targeting the house and home.
Writing in Law: A Case Study of Undergraduate Case Briefs
Creators: name: Oxley, EL
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Applied linguistics and educational linguistics

description: This study is an attempt to expose the linguistic conventions of the Case Brief exercise, a writing task commonly required of beginning tertiary students in law. The Case Brief is a highly conventionalised summary of the reasoning of the presiding judges. Studies of academic and professional genres are becoming more numerous, but so far there are few which have analysed legal genres as represented in the interdiscourse of student writers. The investigation aims to characterise the case summary genre and to highlight some features which present these writers with particular linguistic difficulties. The analysis is based on the Systemic Functional grammar of Halliday (1985/1994), which is concerned with the grammatical choices favoured by speakers/writers in a given context. It is also informed by Swales (1990), Martin (1992) and Bhatia (1993). A total of 27 assessed Case Brief assignments are analysed; 12 written by native speakers (NSs) and 15 by non-native speakers (NNSs). The NNSs were less successful at this task than the NSs. The analysis procedure is ex.lfository and descriptive with some quantification of the data. Major difficulties found at the global level were a misorderi'ng of stages, a failure to present each judge's reasoning separately and the omission of reference to previous cases. The specialised lexis, incongruent realisations and strings of circumstantial elements characteristic of this genre presented problems for these novice writers. They also had difficulty with the verbal moves inherent in reports of the judges' reasoning and with referential relationships. The study concludes that the rationale for the task and its link with linguistic forms must be made explicit to students. Only then can the 'invisible' conventions specific to legal discourse become visible, and thus amenable to teaching and learning. Collaboration between discipline and language specialists can make this possible.

description: We prove that all open string theory disc amplitudes in a flat background obey Britto-Cachazo-Feng-Witten (BCFW) on-shell recursion relations, up to a possible reality condition on a kinematic invariant. Arguments that the same holds for tree level closed string amplitudes are given as well. Non-adjacent BCFW-shifts are related to adjacent shifts through monodromy relations for which we provide a novel CFT based derivation. All possible recursion relations are related by old-fashioned string duality. The field theory limit of the analysis for amplitudes involving gluons is explicitly shown to be smooth for both the bosonic string as well as the superstring. In addition to a proof a less rigorous but more powerful argument based on the underlying CFT is presented which suggests that the technique may extend to a much more general setting in string theory. This is illustrated by a discussion of the open string in a constant B-field background and the closed string on the level of the sphere.

description: An isotropic expansion for the QGP is proposed in curved Kasner spacetime for an experimental configuration with three dimensional set of beams. The fluid of relativistic particles has no shear viscosity but the nonzero bulk viscosity $ζ$ is time dependent and its value could explain the enormous entropy per baryon of our Universe. In addition, $ζ$ equals the bulk viscosity of the anisotropic compressible fluid conjectured for the interior of a black hole.

Growth of agricultural capital and the farm income problem (Canada 1935-1965)
Creators: name: Hladik, Maurice James
Publisher: name: University of British Columbia
Year: 2011

description: Average Canadian farm incomes tend to be consistently lower than non-farm incomes. Many reasons, including aggregate overproduction are advanced as possible explanations of the above problem. This thesis attempts to determine whether overproduction has been one of the causes of the farm income problem. The bulk of information used in this study was time series data as prepared by the Dominion Bureau of Statistics for the years 1935 to 1965. A model was constructed to test two related hypotheses regarding the presence of excess capital formation and its effect on income and overproduction. The basic findings of the study were that capital formation was not greater than required to produce an aggregate supply of agricultural products equal to aggregate demand. The growth in aggregate supply and aggregate demand were found to be very similar for the period 1935 to 1965, thus indicating that the farm income problem was not aggravated during this era by overproduction. In subsequent analysis, a broader view of the problem was undertaken. To begin, it was established that per capita farm incomes have been growing at a rate similar to that of non-farm incomes. In addition the so called "cost-price squeeze" was not found when the entire 1935 to 1965 period was observed but rather was only found in subperiods. Factor share analysis was used to show that agricultural capital offered returns at least equal to the opportunity costs of capital.

description: An accurate knowledge of the neutron capture cross sections of 62,63Ni is crucial since both isotopes take key positions which affect the whole reaction flow in the weak s process up to A=90. No experimental value for the 63Ni(n,gamma) cross section exists so far, and until recently the experimental values for 62Ni(n,gamma) at stellar temperatures (kT=30 keV) ranged between 12 and 37 mb. This latter discrepancy could now be solved by two activations with following AMS using the GAMS setup at the Munich tandem accelerator which are also in perfect agreement with a recent time-of-flight measurement. The resulting (preliminary) Maxwellian cross section at kT=30 keV was determined to be 30keV = 23.4 +/- 4.6 mb. Additionally, we have measured the 64Ni(gamma,n)63Ni cross section close to threshold. Photoactivations at 13.5 MeV, 11.4 MeV and 10.3 MeV were carried out with the ELBE accelerator at Forschungszentrum Dresden-Rossendorf. A first AMS measurement of the sample activated at 13.5 MeV revealed a cross section smaller by more than a factor of 2 compared to NON-SMOKER predictions.

description: In this paper we build models for short-term, mean-term and long-term dynamics of dune and megariple morphodynamics. They are models that are degenerated parabolic equations which are, moreover, singularly perturbed. We, then give an existence and uniqueness result for the short-term and mean-term models. This result is based on a time-space periodic solution existence result for degenerated parabolic equation that we set out. Finally the short-term model is homogenized.

The model includes electronic orbitals necessary to highlight non-local Zhang-Rice singlet, charge transfer and $d$-$d$ excitations, as well as states with apical oxygen 2$p_z$ character. The dispersion of these excitations is discussed with prospects for resonant final state wave-function mapping. A good agreement with experiments emphasizes the substantial multi-orbital character of RIXS profiles in the energy transfer range 1-6 eV.

description: The effect of cyclic adenosine 3', 5' monophosphate (cyclic AMP ) on ionic movement across the cell-membrane of the cellular slime mold Dictyostelium discoideum, strains V-12 and NC4, has been studied by using radioisotopes, Na²² and Ca⁴⁵. D. discoideum was grown on water agar associated with autoclaved radioactive E. coli 281.The experimental amoebae were centrifuged to free them from bacteria. Cyclic AMP was added to the experimental culture every 10 or 20 minutes. The results showed that cyclic AMP has a significant effect on calcium ion movement across the membrane both in the pre-aggregative amoeboid stage and during the aggregating phase. The movement of sodium ion was changed only during aggregation. The addition of phosphodiesterase the enzyme -which inactives cyclic AMP by converting it to 5' AMP, showed no effect on ion transport either in the pre-aggregative stage or the aggregating stage. The ionic contents of sodium, potassium, and calcium, were measured at the slug stage. The relationship of calcium ion and cyclic AMP to amoeboid movement was compared with the role of cyclic AMP in muscular contraction and other function.

description: We generalize the well-known mixtures of Gaussians approach to density estimation and the accompanying Expectation--Maximization technique for finding the maximum likelihood parameters of the mixture to the case where each data point carries an individual $d$-dimensional uncertainty covariance and has unique missing data properties. This algorithm reconstructs the error-deconvolved or "underlying" distribution function common to all samples, even when the individual data points are samples from different distributions, obtained by convolving the underlying distribution with the heteroskedastic uncertainty distribution of the data point and projecting out the missing data directions. We show how this basic algorithm can be extended with conjugate priors on all of the model parameters and a "split-and-merge" procedure designed to avoid local maxima of the likelihood. We demonstrate the full method by applying it to the problem of inferring the three-dimensional velocity distribution of stars near the Sun from noisy two-dimensional, transverse velocity measurements from the Hipparcos satellite.

description: Paul Bernays and David Hilbert carefully avoided overspecification of Hilbert's epsilon-operator and axiomatized only what was relevant for their proof-theoretic investigations. Semantically, this left the epsilon-operator underspecified. In the meanwhile, there have been several suggestions for semantics of the epsilon as a choice operator. After reviewing the literature on semantics of Hilbert's epsilon operator, we propose a new semantics with the following features: We avoid overspecification (such as right-uniqueness), but admit indefinite choice, committed choice, and classical logics. Moreover, our semantics for the epsilon supports proof search optimally and is natural in the sense that it does not only mirror some cases of referential interpretation of indefinite articles in natural language, but may also contribute to philosophy of language. Finally, we ask the question whether our epsilon within our free-variable framework can serve as a paradigm useful in the specification and computation of semantics of discourses in natural language.

description: We study the lattice reaction diffusion model 3A -> 4A, A -> 0 (``triplet creation") using numerical simulations and n-site approximations. The simulation results provide evidence of a discontinuous phase transition at high diffusion rates. In this regime the order parameter appears to be a discontinuous function of the creation rate; no evidence of a stable interface between active and absorbing phases is found. Based on an effective mapping to a modified compact directed percolation process, shall nevertheless argue that the transition is continuous, despite the seemingly discontinuous phase transition suggested by studies of finite systems.

Mapping of Upper Ocean Velocity and Transport in the Cape Farewell Area

Subjects: Physical oceanography

description: The global Thermohaline Circulation (THC), driven by fluxes of heat and fresh water at the ocean surface, is known to be intimately involved with major vanations tn the Earth' climate. The East Greenland Coastal Current (EGCC) together with the East Greenland Current (EGC), represent the major surface currents drawing fresh water southwards in the North Atlantic and therefore play an important role in the THC. By identifying and quantifying Sub-Polar ocean processes such as the EGC we can consolidate our knowledge on present-day climate variability. To do so, hydro graphic data from cruise D298 was analyzed and volume transport calculated. We found that the EGC (initially 8.3 Sv) and the EGCC (initially 1.6 Sv), merge around Cape Farewell and that 2.2 Sv of volume transport is lost in the process. We suggest that a certain volume of the boundary currents is integrated into recirculation cells and that 2 2 Sv is exported southward. Further work is needed on the fresh water fluxes to investigate the exact quantity of fresh water exported from the EGC and EGCC into the North Atlantic.

description: We investigate the combined use of moving NRQCD and stochastic sources in lattice calculations of form factors describing rare B and B_s decays. Moving NRQCD leads to a reduction of discretisation errors compared to standard NRQCD. Stochastic sources are tested for reduction of statistical errors.

description: Temperature dependence of thermoelectric power S(T) of three differently processed Bi2Sr2CaCu2O8 (Bi2212) samples, viz. as-processed melt quenched (Bi2212-MQ), 6000C N2-annealed (Bi2212-N2) and 6000C O2-annealed (Bi2212-O2) is reported here. All the samples possess single-phase character and their superconducting transition temperatures (TcR=0) are 85 K, 90 K and 72 K respectively for Bi2212-MQ, Bi2212-N2 and Bi2212-O2. While Bi2212-MQ and Bi2212-N2 samples are in near optimum doping regime, Bi2212-O2 is an over-doped sample. TcS=0 values obtained through S(T) data are also in line with those deduced from the temperature dependence of resistance and DC magnetization. Interestingly, S(T) behaviour of the optimally-doped Bi2212-MQ and Bi2212-N2 samples is seen to be positive in whole temperature range, it is found negative for the over-doped Bi2212-O2 sample above TcS=0. These results have been seen in the light of the recent band structure calculations and the ensuing split Fermi surface as determined by angle-resolved photoelectron spectroscopy (ARPES).

Some aspects of phenolic acid and iron metabolism in selected bacterial strains
Creators: name: Walsh, Barry L.
Publisher: name: University of British Columbia
Year: 2011

description: Bacillus subtilis and Micrococcus lysodeikticus grew poorly when subjected to conditions of limiting iron nutrition after inocula were washed. Growth of both organisms was stimulated by ferrichrome and various phenolic acids. The chelating agents ethylene-diamine tetraacetic acid and nitrilotriacetic acid stimulated growth of B. subtilis but not of M. lysodeikticus . The effect of these compounds as antagonists to the action of the peptide antibiotic albomycin depended on growth conditions. Phenolic acid production by B. subtilis required relatively high levels of a carbon source, with glucose serving as the most effective substrate of those tested. B. subti lis WB746 produced only 2,3-dihydroxybenzoic acid whereas strain B1471 produced an unidentified phenolic acid early in log phase and 2,3-dihydroxy-benzoylglycine in the late log and early stationary phases of growth, under iron deficient conditions. Mutant strains of B. subtilis produced phenolic acids in the absence or presence of iron in the growth medium. DHB synthesizing enzymes were repressed by growth of B. subtilis in the presence of iron, ferrichrome or the aromatic amino acids. Active dihydroxybenzoic acid synthetase was not affected by these compounds. The DHB synthetase system from B. subtilis was partially purified by DEAE-cellulose column chromatography and sucrose gradient centrifugation; the result suggested the existence of a multienzyme complex. Iron uptake by B. subtilis and typhimurium was shown to be energy-dependent and repressible by growth in the presence of adequate iron. The iron uptake capacity of M. lysodei kticus appeared to be inducible, with a chelating agent or an Fe: chelate complex serving as the inducer. Ferrichrome and dihydroxybenzoic acid appeared to serve as iron transport factors for all three organisms, whereas ethylenediaminetetraacetic acid inhibited iron uptake. 3-F1uorobenzoic acid, a dihydroxybenzoic acid analog, had little effect on growth, but did reduce both phenolic acid production by, and iron uptake capacity of, Bacillus subtilis.
A study of 'common-edge drift' in Norfolk
Creators: name: Wegman, Imogen
Publisher: name: University Of Tasmania
Year: 2023
Subjects: British history

description: The Norfolk landscape has continuously changed and developed over the centuries as farms have grown and amalgamated, towns expanded, and coastlines eroded. Despite this, it retains the shadows of former eras including prehistoric burial mounds, Roman roads, and medieval field patterns. Although post-medieval alterations and additions have influenced the county’s landscape, the settlement patterns were created earlier, in the medieval period. One characteristic feature of this time is the ‘isolated’ parish church. Now standing surrounded by wheat or cows, it is a familiar icon of East Anglia, but one rarely seen elsewhere. Nearly every Norfolk local will have a story of a relative who lives in a small village lying separate from the parish church, and theories about its origins. Rumours of Viking raids, the Plague and over-zealous enclosure abound.

description: We revisit the problem of diffusive proximity systems involving superconductors and normal metals (or ferromagnets) with magnetic disorder. On the length scales much larger than its correlation length, the effect of sufficiently weak magnetic disorder may be incorporated as a local spin-flip term in the Usadel equations. We derive this spin-flip term in the general case of a three-dimensional disordered Zeeman-type field with an arbitrary correlation length. Three different regimes may be distinguished: pointlike impurities (the correlation length is shorter than the Fermi wavelength), medium-range disorder (the correlation length between the Fermi wavelength and the mean free path), and long-range disorder (the correlation length longer than the mean free path). We discuss the relations between these three regimes by using the three overlapping approaches: the Usadel equations, the non-linear sigma model, and the diagrammatic expansion. The expressions for the spin-flip rate agree with the existing results obtained in less general situations.

description: We investigate nonequilibrium properties of the single impurity Anderson model by means of the functional renormalization group (fRG) within Keldysh formalism. We present how the level broadening Gamma/2 can be used as flow parameter for the fRG. This choice preserves important aspects of the Fermi liquid behaviour that the model exhibits in case of particle-hole symmetry. An approximation scheme for the Keldysh fRG is developed which accounts for the frequency dependence of the two-particle vertex in a way similar but not equivalent to a recently published approximation to the equilibrium Matsubara fRG. Our method turns out to be a flexible tool for the study of weak to intermediate on-site interactions U <= 3 Gamma. In equilibrium we find excellent agreement with NRG results for the linear conductance at finite gate voltage, magnetic field, and temperature. In nonequilibrium, our results for the current agree well with TD-DMRG. For the nonlinear conductance as function of the bias voltage, we propose reliable results at finite magnetic field and finite temperature. Furthermore, we demonstrate the exponentially small scale of the Kondo temperature to appear in the second order derivative of the self-energy. We show that the approximation is, however, not able to reproduce the scaling of the effective mass at large interactions.

description: In this paper I think of the 2005 earthquake in Pakistan and Azad Kashmir as an “empirical window” on society providing insights into “common” rather than “exceptional” social processes, practices and power relations. With reference to my ethnographic fieldwork in Muzaffarabad, the capital of Azad Kashmir, I deal with local actors’ perspectives and practices related to the destruction and reconstruction of houses and homes in the earthquake’s aftermath. As an emic category of social practice in society “home” (ghar) refers to flexible arrangements of people, places, things and values, which are closely related to structures and processes of the larger society and the state. Rather than presenting final results, the paper points to some initial analysis of material, social and political processes of house and home examining how social actors re-construct and re-negotiate houses and homes in daily life and thereby struggle over values and resources vis-à-vis state reconstruction policies and activities targeting the house and home.
