title:  Rovine e macerie. Permanenze e rimozioni dell’identità coloniale nel cinema italiano dal secondo dopoguerra alle migrazioni contemporanee
Creators: name: Piredda  , Maria Francesca
Publisher: name: RomaTrE-Press
Year: 2019

description: Il saggio intende indagare la funzione del cinema nei processi di rielaborazione memoriale dell’esperienza coloniale italiana e di costruzione dell’identità post-coloniale. Da un lato, prendendo in considerazione film “scomodi” che hanno tentato di raccontare il colonialismo italiano al di fuori della retorica dominante e che, forse proprio per questo, hanno subito un ostracismo produttivo e distributivo. Dall’altro, rintracciando le “irruzioni fantasma”, entro il tessuto narrativo di alcuni esempi significativi del cinema contemporaneo, di personaggi e situazioni che sembrano alludere alla nostra storia coloniale e ai processi di rielaborazione memoriale di cui è stata oggetto.

description: We present a proposal and a feasibility study for the creation and quantum state tomography of a single polariton state of an atomic ensemble. The collective non-classical and non-Gaussian state of the ensemble is generated by detection of a single forward scattered photon. The state is subsequently characterized by atomic state tomography performed using strong dispersive light-atoms interaction followed by a homodyne measurement on the transmitted light. The proposal is backed by preliminary experimental results showing projection noise limited sensitivity and a simulation demonstrating the feasibility of the proposed method for detection of a non-classical and non-Gaussian state of the mesoscopic atomic ensemble. This work represents the first attempt of hybrid discrete-continuous variable quantum state processing with atomic ensembles.

description: ABSTRACT  The Think/No-Think (TNT) paradigm is an influential approach to studying the control of unwanted memories. Participants first learn a series of cue-target pairs (BEACH-AFRICA) until the cue reliably elicits the target; then for a subset of the cues (BEACH) they practice avoiding retrieval of the target (AFRICA). Evidence from this paradigm suggests that intentionally not retrieving unwanted experiences renders those experiences less accessible at test. This is referred to as the Suppression-Induced Forgetting (SIF) effect and has been linked to a variety of conditions involving unwanted past or future experiences. The SIF effect obtained with independent retrieval cues has been suggested to provide compelling evidence for the existence of cognitive inhibition. However, some researchers have questioned its replicability. The present Registered Report will address these concerns by replicating the TNT paradigm using two common instructional variants (Thought Substitution and Thought Avoidance) previously shown to reduce the accessibility of unwanted memories.

description: To quantify the wider impacts of increased graft survival on the size of the kidney transplant waitlist and health and economic outcomes. The analysis employed steady-state solutions and a simulation version of a double-queuing model. Baseline input parameters were sourced from the Organ Procurement and Transplant Network and the United States Renal Data System. Three increased graft survival scenarios were modeled: decreases in repeat transplant candidates joining the waitlist of 25%, 50%, and 100%. Under the three scenarios, we estimated that the US waitlist size would decrease from 91,822 to 85,461 (6.9% decrease), 80,073 (12.8% decrease), and 69,340 (24.4% decrease), respectively. Patient outcomes improved, with lifetime quality-adjusted life years (QALYs) for a one-year cohort of transplant recipients increasing by 10,010, 16,888, and 43,345 over the three scenarios. Discounted lifetime costs for the cohort in the new steady state were lower by $1.6 billion, $2.3, billion, and $9.0 billion for each scenario, respectively. Spillover impacts (i.e., benefits that accrued beyond the patients who directly experienced increased graft survival) accounted for 41–48% of the QALY gains and ranged from cost increases of 3.3% to decreases of 5.5%. The model is a simplification of reality and does not account for the full degree of patient heterogeneity occurring in the real world. Health economic outcomes are extrapolated based on the assumption that the median patient is representative of the overall population. Increasing graft survival reduces demand from repeat transplants candidates, allowing additional candidates to receive transplants. These spillover impacts decrease waitlist size and shorten wait times, leading to improvements in graft and patient survival as well as quality of life. Cost-effectiveness analyses of treatments that increase kidney graft survival should incorporate spillover benefits that accrue beyond the direct recipient of an intervention.

description: Perceived footwear comfort influences wearability and can impact on physical mobility, performance and foot-related complaints. To date, there has been no comprehensive review of the characteristics or methods for measuring perceived footwear comfort. The aims of this systematic review were to identify, appraise and synthesise the literature on methods used to assess perceived footwear comfort, and report their validity and reliability. Electronic databases were systematically searched and the articles screened and appraised for methodological risk of bias using a modified Quality Index checklist. Data on footwear comfort assessment tools (methods, populations, footwear types, reliability/validity) was extracted by two reviewers. A narrative synthesis was undertaken to describe the findings. Ninety-nine articles involving 6980 participants were assessed as eligible for review. Perceived footwear comfort has been assessed by a variety of methods including the visual analogue scale (VAS), Likert-type scales, ranking scales and questionnaires. The studies have covered a range of populations, both healthy and pathological, ranging between ages 8 and 75 years, most commonly adults. Investigations into reliability of perceived footwear comfort scales were limited, and whilst some tools had evidence of moderate to high reliability, findings were population dependent. Developmental or independent validity testing was typically not undertaken. Risk of bias was variable across studies. Perceived footwear comfort assessment has been performed across a wide range of populations and footwear types. Whilst select measures had evidence for their reliability, the results were variable and population dependent. There is scope for further research into the reliability and validity of perceived footwear comfort assessment tools in different populations.

description: We consider a linear feeder connecting multiple distributed loads and generators to the sub-station. Voltage is controlled directly at the sub-station, however, voltage down the line shifts up or down, in particular depending on if the feeder operates in the power export regime or power import regime. Starting from this finite element description of the feeder, assuming that the consumption/generation is distributed heterogeneously along the feeder, and following the asymptotic homogenization approach, we derive simple low-parametric ODE model of the feeder. We also explain how the homogeneous ODE modeling is generalized to account for other distributed effects, e.g. for inverter based and voltage dependent control of reactive power. The resulting system of the DistFlow-ODEs, relating homogenized voltage to flows of real and reactive power along the lines, admits computationally efficient analysis in terms of the minimal number of the feeder line "media" parameters, such as the ratio of the inductance-to-resistance densities. Exploring the space of the media and control parameters allows us to test and juxtapose different measures of the system performance, in particular expressed in terms of the voltage drop along the feeder, power import/export from the feeder line as the whole, power losses within the feeder, and critical (with respect to possible voltage collapse) length of the feeder. Our most surprising funding relates to performance of a feeder rich on PhotoVoltaic (PV) systems during a sunny day. We observe that if the feeder is sufficiently long the DistFlow-ODEs may have multiple stable solutions. The multiplicity may mean troubles for successful recovery of the feeder after a very short, few periods long, fault at the head of the line.

description: Title: Combatting Human Trafficking in the Cyberspace: A Natural Language Processing-Based Methodology to Analyze the Language in Online AdvertisementsDescription:This thesis addresses the critical issue of human trafficking within online consumer-to-consumer (C2C) marketplaces, employing advanced Natural Language Processing (NLP) techniques. The primary goal is to develop a robust, scalable machine learning-driven approach to identify and combat human exploitation online, filling a significant gap in both academic research and practical application.Methodology:The research introduces a novel methodology for generating pseudo-labeled datasets with minimal supervision. These datasets are instrumental in training state-of-the-art NLP models, specifically focusing on tasks like Human Trafficking Risk Prediction (HTRP) and Organized Activity Detection (OAD). The study extensively uses cutting-edge Transformer models, which are at the forefront of NLP research, to analyze and interpret the language used in online advertisements that could be linked to human trafficking.A significant contribution of this work is the implementation of an interpretability framework using Integrated Gradients. This aspect is crucial in providing explainable insights into the NLP models' decision-making processes, which is of immense value for law enforcement agencies in their efforts to detect and prevent human trafficking activities online.Ethical and Legal Considerations:The research strictly adheres to ethical and legal standards, especially considering the sensitivity of the subject and the data involved. All data collection and analysis methods comply with relevant data protection and privacy regulations. The thesis also discusses the ethical considerations of using AI and machine learning in sensitive areas such as human trafficking, emphasizing the need for responsible and ethical AI practices.Relevance and Impact:The outcomes of this research offer a scalable and effective tool for law enforcement and other relevant stakeholders in the fight against human trafficking. By leveraging the latest advancements in AI and NLP, this work paves the way for future research and practical applications that emphasize the role of technology in addressing complex social issues like human trafficking. This thesis not only contributes significantly to the academic discourse in computational criminology and AI ethics but also provides a practical framework that can be adopted and adapted for real-world applications.
A Collective Breaking of R-Parity

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Supersymmetric theories with an R-parity generally yield a striking missing energy signature, with cascade decays concluding in a neutralino that escapes the detector. In theories where R-parity is broken the missing energy is replaced with additional jets or leptons, often making traditional search strategies ineffective. Such R-parity violation is very constrained, however, by resulting B and L violating signals, requiring couplings so small that LSPs will decay outside the detector in all but a few scenarios. In theories with additional matter fields, R-parity can be broken collectively, such that R-parity is not broken by any single coupling, but only by an ensemble of couplings. Cascade decays can proceed normally, with each step only sensitive to one or two couplings at a time, but B and L violation requires the full set, yielding a highly suppressed constraint. s-channel production of new scalar states, typically small for standard RPV, can be large when RPV is broken collectively. While missing energy is absent, making these models difficult to discover by traditional SUSY searches, they produce complicated many object resonances (MORes), with many different possible numbers of jets and leptons. We outline a simple model and discuss its discoverability at the LHC.

description: We study dyonic soliton and black hole solutions of the ${\mathfrak {su}}(2)$ Einstein-Yang-Mills equations in asymptotically anti-de Sitter space. We prove the existence of non-trivial dyonic soliton and black hole solutions in a neighbourhood of the trivial solution. For these solutions the magnetic gauge field function has no zeros and we conjecture that at least some of these non-trivial solutions will be stable. The global existence proof uses local existence results and a non-linear perturbation argument based on the (Banach space) implicit function theorem.

Massive and Newly Dead: Discovery of a Significant Population of Galaxies with High Velocity Dispersions and Strong Balmer Lines at z~1.5 from Deep Keck Spectra and HST/WFC3 Imaging

description: We present deep Keck/LRIS spectroscopy and HST/WFC3 imaging in the rest-frame optical for a sample of eight galaxies at z~1.5 with high photometrically-determined stellar masses. The data are combined with VLT/XShooter spectra of five galaxies from van de Sande et al. (2011, 2012 to be submitted). We find that these thirteen galaxies have high velocity dispersions, with a median of sigma=301 km s^{-1}. This high value is consistent with their relatively high stellar masses and compact sizes. We study their stellar populations using the strength of Balmer absorption lines, which are not sensitive to dust absorption. We find a large range in Balmer absorption strength, with many galaxies showing very strong lines indicating young ages. The median Hdelta_A equivalent width, determined directly or inferred from the H10 line, is 5.4 Angstroms, indicating a luminosity-weighted age of ~1 Gyr. Although this value may be biased towards higher values because of selection effects,high-dispersion galaxies with such young ages are extremely rare in the local Universe. Interestingly we do not find a simple correlation with rest-frame U-V color: some of the reddest galaxies have very strong Balmer absorption lines. These results demonstrate that many high-dispersion galaxies at z~1.5 were quenched recently. This implies that there must be a population of star-forming progenitors at z~2 with high velocity dispersions or linewidths, which are notoriously absent from CO/Halpha selected surveys.

description: We investigate the influence of different metals on the electromagnetic response of fishnet metamaterials in the optical regime.We found, instead of using a Drude model, metals with a dielectric function from experimentally measured data should be applied to correctly predict the behavior of optical metamaterials. Through comparison of the performance for fishnet metamaterials made with different metals (i.e., gold, copper, and silver), we found silver is the best choice for the metallic parts compared to other metals, because silver allows for the strongest negative-permeability resonance and, hence, for optical fishnet metamaterials with a high figure-of-merit. Our study offers a valuable reference in the designs for optical metamaterials with optimized properties.

description: We use data from the WMAP temperature maps to constrain a scale-dependent generalization of the popular 'local' model for primordial non-Gaussianity. In the model where the parameter fNL is allowed to run with scale k, fNL(k) = fNL* (k/k_piv)^n, we constrain the running to be n = 0.30(+1.9)(-1.2) at 95% confidence, marginalized over the amplitude fNL*. The constraints depend somewhat on the prior probabilities assigned to the two parameters. In the near future, constraints from a combination of Planck and large-scale structure surveys are expected to improve this limit by about an order of magnitude and usefully constrain classes of inflationary models.

description: Starting from first principle many-body quantum dynamics, we show that the dynamics of Bose-Einstein condensates can be approximated by the time-dependent nonlinear Gross-Pitaevskii equation, giving a bound on the rate of the convergence. Initial data are constructed on the bosonic Fock space applying an appropriate Bogoliubov transformation on a coherent state with expected number of particles N. The Bogoliubov transformation plays a crucial role; it produces the correct microscopic correlations among the particles. Our analysis shows that, on the level of the one particle reduced density, the form of the initial data is preserved by the many-body evolution, up to a small error which vanishes as N^{-1/2} in the limit of large N.

description: Business information security has evolved over the years, where it first started as a technique to protect critical information assets from the growing use of information technology and its accompanying risks, it now has grown to a topic widely discussed on board level. Cybercrime also has evolved to being much more than an attempt to steal logical, information assets. Hardware assets, networks, servers, employees and even organizations themselves have become targets. Organizations must ensure that they remain viable against the rising and evolving threats of utilizing information technology and its accompanying risks. In order to provide guidance, this research attempts to provide concepts from the Viable System Model, established by Stafford Beer, in order to diagnose the viability and resistance against cyber threats. Using concepts from management cybernetics and this viable system model, this research, furthermore, proposes a new holistic way of looking at business information security and to step away from silo thinking and looking at the organization and its organization of security management and governance as a whole.

description: Cavendish bananas are efficiently propagated through micropropagation (tissue culture). However, the risk of virus transmission especially Banana Bunchy Top Virus (BBTV) in micropropagated plants is also present (Thomas, J. E. et.al, 1995). With this, it is important to ensure that the materials used for micropropagation are virus-free. At present, ELISA and Conventional PCR are used for BBTV detection but the procedures have limitations in terms of the time required during sample preparation and the availability of the results. This study describes a fast and reliable real-time PCR detection of BBTV from explant sources for micropropagation of Cavendish banana.

description: Identifying the electromagnetic counterparts of gravitational wave (GW) sources detected by upcoming networks of advanced ground-based interferometers will be challenging due in part to the large number of unrelated astrophysical transients within the ~10-100 square degree sky localizations. A potential way to greatly reduce the number of such false positives is to limit detailed follow-up to only those candidates near galaxies within the GW sensitivity range of ~200 Mpc for binary neutron star mergers. Such a strategy is currently hindered by the fact that galaxy catalogs are grossly incomplete within this volume. Here we compare two methods for completing the local galaxy catalog: (1) a narrow-band H-alpha imaging survey; and (2) an HI emission line radio survey. Using H-alpha fluxes, stellar masses (M_star), and star formation rates (SFR) from galaxies in the Sloan Digital Sky Survey (SDSS), combined with HI data from the GALEX Arecibo SDSS Survey and the Herschel Reference Survey, we estimate that a H-alpha survey with a luminosity sensitivity of L_H-alpha = 1e40 erg/s at 200 Mpc could achieve a completeness of f_SFR ~ 75% with respect to total SFR, but only f_Mstar ~ 33% with respect to stellar mass (due to lack of sensitivity to early-type galaxies). These numbers are significantly lower than those achieved by an idealized spectroscopic survey due to the loss of H-alpha flux resulting from resolving out nearby galaxies and the inability to correct for the underlying stellar continuum. An HI survey with sensitivity similar to the proposed WALLABY survey on ASKAP could achieve f_SFR ~ 80% and f_Mstar ~ 50%, somewhat higher than that of the H-alpha survey. Finally, both H-alpha and HI surveys should achieve > 50% completeness with respect to the host galaxies of short duration gamma-ray bursts, which may trace the population of binary neutron star mergers.

description: We study for the first time the effect of the geometry of quantum wire networks on their nonlinear optical properties and show that for some geometries, the first hyperpolarizability is largely enhanced and the second hyperpolarizability is always negative or zero. We use a one-electron model with tight transverse confinement. In the limit of infinite transverse confinement, the transverse wavefunctions drop out of the hyperpolarizabilities, but their residual effects are essential to include in the sum rules. The effects of geometry are manifested in the projections of the transition moments of each wire segment onto the 2-D lab frame. Numerical optimization of the geometry of a loop leads to hyperpolarizabilities that rival the best chromophores. We suggest that a combination of geometry and quantum-confinement effects can lead to systems with ultralarge nonlinear response.

description: From Anthropology to Sociology, many of the historically minded Social Sciences and Cultural Studies have been interested in the subjects of ecstasy, trance and intoxication for a quite a long tme. This article seeks to assemble ideas and outline perspectives for researching the history of ecstatic and/or intoxicated bodies. It draws on approaches from the history of drugs in modern societies and proposes combining them with genealogical and praxeological accounts. The authors argue that these research tools can be fruitful for an integrative approach that can analyze the body history of various forms of ‘Rausch’, such as drug experiences, religious trances, sexual ecstasies, or similar feelings during sports or violence under a common denominator. They want to encourage body historians to focus on the practical production of ecstasies and intoxications and put them even more into the foreground of their research interest. From this angle, the discourses and practices of ‘Rausch’, their embeddedness in socio-technical contexts, and the collectives and self-relations they formed and transformed in the 19th and 20th centuries can be analyzed as techniques of modern body politics.

description: We theoretically investigate the electronic and optical properties of semiconductor Cu3PSe4. We also report diffuse reflectance spectroscopy measurements for Cu3PSe4 and Cu3PS4, which indicate a band gap of 1.40 eV for the former.Hybrid functional calculations agree well with this value, and reveal that the band gap is direct. Calculations yield an optical absorption spectrum similar to GaAs in the visible region, with α > 5x10^4 cm^-1 for λ < 630 nm. We conclude that the optical properties of Cu3PSe4 are within the desired range for a photovoltaic solar absorber material.

description: Evidence on whether diversifying farm production leads to improved household dietary diversity and nutrition remains inconclusive. Existing studies analyzing the link between production diversity and dietary diversity are mainly based on cross-sectional methods, which could be biased by omitted confounding factors. Using two waves of a panel household survey of 900 rural households in Tanzania, this paper examines the link between production diversity and dietary diversity, while minimizing potential confounding effects. We estimate four regression models with two different production diversity measures and two panel estimation methods—fixed effect (FE) and random effect (RE). In three out of the four models, production diversity is significantly and positively associated with the dietary diversity measure of the food consumption score. The production diversity indicator is represented by the total crop and livestock species count, as well as by counting only crop species. The total crop and livestock species count shows a significant positive association with dietary diversity across estimation methods while the positive association with crop species count is not significant in the FE method. Our results suggest that the selection of appropriate production diversity indicators tailored to the specific circumstances of the local agricultural system is likely one key factor in identifying a robust relationship between production diversity and dietary diversity.

Supernova Light Curves Powered by Fallback Accretion

description: Some fraction of the material ejected in a core collapse supernova explosion may remain bound to the compact remnant, and eventually turn around and fall back. We show that the late time (> days) power associated with the accretion of this "fallback" material may significantly affect the optical light curve, in some cases producing super-luminous or otherwise peculiar supernovae. We use spherically symmetric hydrodynamical models to estimate the accretion rate at late times for a range of progenitor masses and radii and explosion energies. The accretion rate onto the proto-neutron star or black hole decreases as Mdot ~ t^-5/3 at late times, but its normalization can be significantly enhanced at low explosion energies, in very massive stars, or if a strong reverse shock wave forms at the helium/hydrogen interface in the progenitor. If the resulting super-Eddington accretion drives an outflow which thermalizes in the outgoing ejecta, the supernova debris will be re-energized at a time when photons can diffuse out efficiently. The resulting light curves are different and more diverse than previous fallback supernova models which ignored the input of accretion power and produced short-lived, dim transients. The possible outcomes when fallback accretion power is significant include super-luminous (> 10^44 ergs / s) Type II events of both short and long durations, as well as luminous Type I events from compact stars that may have experienced significant mass loss. Accretion power may unbind the remaining infalling material, causing a sudden decrease in the brightness of some long duration Type II events. This scenario may be relevant for explaining some of the recently discovered classes of peculiar and rare supernovae.

Delayed Onset and Fast Rise of Prompt Optical-UV Emission from Gamma-Ray Bursts in Molecular Clouds

description: Observations imply that long γ-ray bursts (GRBs) are originated from explosions of massive stars, therefore they may occur in the molecular clouds where their progenitors were born. We show here that the prompt optical-UV emission from GRBs may be delayed due to the dust extinction, which can well explain the observed optical delayed onset and fast rise in GRB 080319B. The density and the size of the molecular cloud around GRB 080319B are roughly constrained to be \sim10^3cm^{-3} and \sim 8pc, respectively. We also investigate the other GRBs with prompt optical-UV data, and find similar values of the densities and sizes of the local molecular clouds. The future observations of prompt optical-UV emission from GRBs in subsecond timescale, e.g., by UFFO-Pathfinder and SVOM-GWAC, will provide more evidence and probes of the local GRB environments.

description: The influence of the shear stress and angular momentum on the nonlinear spherical collapse model is discussed in the framework of the Einstein-de Sitter (EdS) and $Λ$CDM models. By assuming that the vacuum component is not clustering within the homogeneous nonspherical overdensities, we show how the local rotation and shear affects the linear density threshold for collapse of the non-relativistic component ($δ_\mathrm{c}$) and its virial overdensity ($Δ_\mathrm{V}$). It is also found that the net effect of shear and rotation in galactic scale is responsible for higher values of the linear overdensity parameter as compared with the standard spherical collapse model (no shear and rotation).

description: Banana is a major staple food crop for millions of people and provides income through local and international trade. However, global banana production is seriously threatened by various constraints, among which is Fusarium wilt, considered as one of the most important destructive diseases in the world (Ploetz et. al. 2003). The use of microbial biological control agents constitutes a promising and environmentally-friendly approach (Bubici et. al. 2019) especially in Cavendish banana which are grown in monocultures with large pesticide inputs (Catambacan and Cumagun 2021). Plant-associated microorganisms and soil microbiome play a vital role in soil health and immunity to plant diseases (Berendsen et. al. 2012). With this, it is worth exploring the banana plant rhizosphere and root endophytic microbial communities which may play essential roles in the defense against soil borne pathogens like Fusarium oxysporum f. sp. cubense Tropical Race 4 (FocTR4).

description: Jakob Tanner is one of the pioneers of body and drug history in German-speaking historiography. For decades he has been one of the most important protagonists of an analytical framework that combines social history with the history of knowledge and historical-anthropological approaches. In this interview, Tanner reflects upon the topic of this issue of Body Politics and explains how the concept ‚Rausch‘ can enrich and contribute to the historiographical examination of modern societies. Additionally, he discusses different theoretical and methodical approaches that are used in studies on the history of drugs and ‚Rausch‘. In this context, he also points to ideas and problems, which are currently debated in this field of historical studies. In addition to statements on the relation between language and ecstatic experiences, Tanner comments on classical narratives and new analytical tools. In the course of the interview, he repeatedly emphasizes the changing meanings, which different historical actors ascribed t states of ecstasy, trance, and intoxication. He draws attention to the interrelationships that shaped the perception of concepts and practices of drug use in specific historical constellations and contexts. Once more, Tanners statements direct the focus on the entanglement of notions of ‚Rausch‘, drug politics, and social power structures.
