description: Herschel and Planck are surveying the sky at unprecedented angular scales and sensitivities over large areas. But both experiments are limited by source confusion in the submillimeter. The high confusion noise in particular restricts the study of the clustering properties of the sources that dominate the cosmic infrared background. At these wavelengths, it is more appropriate to consider the statistics of the unresolved component. In particular, high clustering will contribute in excess of Poisson noise in the power spectra of CIB anisotropies. These power spectra contain contributions from sources at all redshift. We show how the stacking technique can be used to separate the different redshift contributions to the power spectra. We use simulations of CIB representative of realistic Spitzer, Herschel, Planck, and SCUBA-2 observations. We stack the 24um sources in longer wavelengths maps to measure mean colors per redshift and flux bins. The information retrieved on the mean spectral energy distribution obtained with the stacking technique is then used to clean the maps, in particular to remove the contribution of low-redshift undetected sources to the anisotropies. Using the stacking, we measure the mean flux of populations 4 to 6 times fainter than the total noise at 350um at redshifts z=1 and z=2, respectively, and as faint as 6 to 10 times fainter than the total noise at 850um at the same redshifts. In the deep Spitzer fields, the detected 24um sources up to z~2 contribute significantly to the submillimeter anisotropies. We show that the method provides excellent (using COSMOS 24um data) to good (using SWIRE 24um data) removal of the z<2 (COSMOS) and z<1 (SWIRE) anisotropies. Using this cleaning method, we then hope to have a set of large maps dominated by high redshift galaxies for galaxy evolution study (e.g., clustering, luminosity density).

description: La scolarizzazione è un diritto fondamentale garantito a tutti i bambini, indipendentemente dal proprio stato di salute. Questo è particolarmente sfidante nell’accoglienza in un contesto scolastico frequentato da un alto numero di allievi un bambino affetto da diabete mellito di tipo 1, che richiede un’attenzione particolare e uno sguardo costante da parte dell’insegnante. In questo documento ho cercato di identificare le condizioni necessarie affinché l’inserimento di un allievo con diabete avvenga nel modo più sereno e quindi efficace possibile per tutti i soggetti coinvolti, ponendo un’attenzione particolare ai vissuti che accompagnano i docenti durante questo percorso. Per indagare questo campo di ricerca, ho realizzato delle interviste a docenti attivi sul territorio ticinese che negli ultimi anni hanno accolto un allievo affetto da diabete all’interno della propria classe, dando ampio spazio ai loro vissuti e alle loro opinioni riguardanti il tema. Ci sono in particolare tre aspetti che i docenti ritengono fondamentali affinché la scolarizzazione di un allievo con diabete sia possibile: la formazione di una solida rete di sostegno attorno al docente creata da tutti i soggetti coinvolti, in particolare le famiglie dell’allievo e l’inserimento di un eventuale aiuto esterno; il contesto in cui è inserito facilita l’accoglienza se non presenta un numero troppo elevato si sfide educative; il docente ha bisogno di essere formato e supportato nella gestione della malattia.

description: Models of weak-scale supersymmetry offer viable dark matter (DM) candidates. Their parameter spaces are however rather large and complex, such that pinning down the actual parameter values from experimental data can depend strongly on the employed statistical framework and scanning algorithm. In frequentist parameter estimation, a central requirement for properly constructed confidence intervals is that they cover true parameter values, preferably at exactly the stated confidence level when experiments are repeated infinitely many times. Since most widely-used scanning techniques are optimised for Bayesian statistics, one needs to assess their abilities in providing correct confidence intervals in terms of the statistical coverage. Here we investigate this for the Constrained Minimal Supersymmetric Standard Model (CMSSM) when only constrained by data from direct searches for dark matter. We construct confidence intervals from one-dimensional profile likelihoods and study the coverage by generating several pseudo-experiments for a few benchmark sets of pseudo-true parameters. We use nested sampling to scan the parameter space and evaluate the coverage for the benchmarks when either flat or logarithmic priors are imposed on gaugino and scalar mass parameters. The sampling algorithm has been used in the configuration usually adopted for exploration of the Bayesian posterior. We observe both under- and over-coverage, which in some cases vary quite dramatically when benchmarks or priors are modified. We show how most of the variation can be explained as the impact of explicit priors as well as sampling effects, where the latter are indirectly imposed by physicality conditions. For comparison, we also evaluate the coverage for Bayesian credible intervals, and observe significant under-coverage in those cases.

description: In that work, a comparative optimal 2D gas-dynamic calculation was performed on the nominal mode of three design diagrams of gas turbines in the OPTBGT software package. Then a multi-mode computer optimisation of the flow part of the traditional and birotative two-stage gas turbine was carried out. According to the results of the calculations, the stator blades of the second stages of turbines of two types in the KOMPAS-3D program are profiled. Using the models obtained, a 3D verification was carried out - gas-dynamic calculation of the flow around the second-stage guide gratings in the ANSYS CFX program and conclusions were drawn on the reasonability of using birotational circuits in turboshaft engines.
A Wiener-Hopf Type Factorization for the Exponential Functional of Levy Processes

description: For a Lévy process $ξ=(ξ_t)_{t\geq0}$ drifting to $-\infty$, we define the so-called exponential functional as follows \[{\rm{I}}_ξ=\int_0^{\infty}e^{ξ_t} dt.\] Under mild conditions on $ξ$, we show that the following factorization of exponential functionals \[{\rm{I}}_ξ\stackrel{d}={\rm{I}}_{H^-} \times {\rm{I}}_{Y}\] holds, where, $\times $ stands for the product of independent random variables, $H^-$ is the descending ladder height process of $ξ$ and $Y$ is a spectrally positive Lévy process with a negative mean constructed from its ascending ladder height process. As a by-product, we generate an integral or power series representation for the law of ${\rm{I}}_ξ$ for a large class of Lévy processes with two-sided jumps and also derive some new distributional properties. The proof of our main result relies on a fine Markovian study of a class of generalized Ornstein-Uhlenbeck processes which is of independent interest on its own. We use and refine an alternative approach of studying the stationary measure of a Markov process which avoids some technicalities and difficulties that appear in the classical method of employing the generator of the dual Markov process.
(Un)desirable immigrants: the perpetuation of colonial perspectives in South African immigration policies in the twentieth century
Creators: name: Nicolaides, Ariel
Publisher: name: University of British Columbia
Year: 2020

description: This thesis examines the history of immigration policy in South Africa and provides valuable insights into the development of modern immigration in the wake of colonialism, with a particular look into British imperialism, a global phenomenon that at its height encompassed countries colonized and ruled by the United Kingdom, resulting in widespread political, cultural, and linguistic similarities. A history of early diffusion of knowledge enabled the spread of colonization within South Africa from both Afrikaners and British populations, impacting those that were seen as ‘insiders’ and ‘outsiders’ within the population. This trend can be seen throughout the twentieth century through the examination of immigration policies as desirable immigrants were sought while those considered undesirable were excluded. Starting in the late nineteenth century and into the early twentieth century, imperialist citizenship and nationalist citizenship have been at the forefront of immigration policy within the dominions. Colonial ideas of a white, Anglo-Saxon ruling class in the settler countries permeated despite many subjects in the British Empire being non-white. While Britain maintained on an international stage a level of equality, nationalist ideas in the dominions dominated. As a result, many of the countries within the British Empire began adopting subtle and not so subtle restrictive policies, learning from one another and adapting the policy for themselves. The colonial ideas were not only spread at a domestic level but also internationally through bodies such as the United Nations. This thesis examines the case study of the Mozambique refugee immigration in South Africa from 1980 until 1996 to help further my argument. From 1948 until 1994, South Africa was under apartheid rule, which did not develop a refugee policy. Yet, they allowed indigenous, Mozambican refugees to settle within the rural areas along the border. In 1994, the United Nations High Commissioner for Refugees (UNHCR) implemented a Voluntary Repatriation Programme in South Africa and although it was supposed to be protective, it created exclusionary boundaries for Mozambicans seeking citizenship. The lingering legacy of colonization has had enduring effects on immigration policy in South Africa, resulting in repercussions for immigration today.

description: We numerically examine the spatial evolution of the structure of coherent and partially coherent laser beams (PCBs), including the optical vortices, propagating in turbulent atmospheres. The influence of beam fragmentation and wandering relative to the axis of propagation (z-axis) on the value of the scintillation index (SI) of the signal at the detector is analyzed. A method for significantly reducing the SI, by averaging the signal at the detector over a set of PCBs, is described. This novel method is to generate the PCBs by combining two laser beams - Gaussian and vortex beams, with different frequencies (the difference between these two frequencies being significantly smaller than the frequencies themselves). In this case, the SI is effectively suppressed without any high-frequency modulators.

description: Questo lavoro di diploma nasce dal desiderio di integrare nel programma d’insegnamento dell’inglese come lingua straniera materiale input più accattivante per le fasce d’età degli studenti delle scuole medie, per aumentare la loro motivazione all’apprendimento e allo stesso tempo sviluppare le quattro competenze linguistiche in modo efficace. Sono state quindi raccolte le diverse modalità di utilizzo dei film e delle serie TV come strumenti didattici, entrambi media molto popolari fra i giovani d’oggi, con lo scopo di illustrare i modi in cui questi media possono essere usati per creare un'atmosfera di classe coinvolgente e motivante che aiuterà gli studenti ad essere più consapevoli della lingua e della sua cultura. Nella prima parte del lavoro, è stata fatta una rassegna del film e le sue possibili applicazioni didattiche, in cui vengono presentati i benefici primari di questo tipo di input e delle indicazioni generali da seguire quando si decide di usare questo media in classe. Nella seconda parte, il focus è spostato sulle serie TV, sulle peculiarità che le distinguono dal film e su come è possibile sfruttarle a livello didattico. Ne scaturisce la particolare versatilità delle serie TV per l’apprendimento dell’inglese in classe, grazie al formato a episodi più facilmente adattabile alle ore lezione, così come la ricorrenza di contesti e personaggi, i fandom online e la presenza di elementi culturali importanti.

description: We combine the high-resolution Aquarius simulations with three-dimensional models of reionization based on the initial density field of the Aquarius parent simulation, Millennium-II, to study the impact of patchy reionization on the faint satellite population of Milky Way halos. Because the Aquarius suite consists of zoom-in simulations of halos in the Millennium-II volume, we follow the formation of substructure and the growth of reionization bubbles due to the larger environment simultaneously, and thereby determine the reionization redshifts of satellite candidates. We do this for four different reionization models, and also compare results to instantaneous reionization. Using a simple procedure for selecting satellites and assigning luminosities in the simulations, we compare the resulting satellite populations. We find that the overall number of satellites depends sensitively on the reionization model, with a factor of 3-4 variation between the four models for a given host halo, although the difference is entirely in the population of faint satellites (M_V > -10). In addition, we find that for a given reionization model the total number of satellites differs by 10%-20% between the patchy and homogeneous scenarios, provided that the redshift is chosen appropriately for the instantaneous case. However, the halo-halo scatter from the six Aquarius halos is large, up to a factor of 2-3, and so is comparable to the difference between reionization scenarios. In order to use the population of faint dwarf galaxies around the Milky Way as a probe of the local reionization history, then, it is necessary to first better understand the general distribution of substructure around Milky Way-mass halos.

description: Objective: This study aimed to compare COVID-19 positivity by HIV status and race/ethnicity using data from the U.S. National COVID Cohort Collaborative (N3C). Methods: The N3C cohort (≥ 18 years) includes patients with any encounter after 1/1/2020 with SARS-CoV-2 laboratory tests. Detailed electronic medical records are centralized and harmonized across health-care organizations (34 sites). COVID-19 diagnosis was defined by RT-PCR or antibody testing. HIV infection was defined by standard diagnostic codes within 2 years prior to COVID-19 testing. Descriptive statistics and multivariable logistic regression were utilized to compare COVID-19 positivity and HIV status by patient’s race/ethnicity. Results: Over 2.1 million patients were captured in the N3C as of 01/29/2021, of whom 372,716 (15%) were positive for COVID-19; 17,820 (0.7%) were PLWH of whom 2428 (13.6%) tested positive for COVID-19. COVID-19 positive PLWH were more likely to be 30+ years of age (90% vs. 70%; χ2p < 0.001), male (67% vs. 46%, χ2p < 0.001), and Black (44% vs. 15%, χ2p < 0.001) compared to HIV-negative patients. Compared to non-Hispanic/Latinx (NH)-White PLWH, NH-Black (aOR: 1.59, 95% CI: 1.37–1.86), Latinx (aOR: 2.17, 95% CI: 1.68–2.83), and NH-Asian (aOR: 2.18, 95% CI: 1.30–3.63) PLWH were more likely to have COVID-19 after adjustment for age, sex, and CharlsonDeyo comorbidity score. Conclusion: PLWH and minoritized communities, including NH-Black and Latinx or Hispanic adults, appear to be disproportionately impacted by the COVID-19 pandemic.

description: The prognostic significance of suPAR in various kidney diseases has recently been demonstrated. Its role in transplantation-specific outcomes is still largely unknown. Therefore, we prospectively investigated the prognostic relevance of suPAR in patients before and one year after kidney transplantation (KTx). We included 100 patients who had received a kidney transplantation between 2013 and 2015. The plasma concentration of suPAR was measured by ELISA assay. In recipients of living donations (LD), pre-transplant suPAR levels were significantly lower than those of recipients of deceased donations (DD). After KTx, suPAR levels significantly declined in LD and DD recipients, without a detectable difference between both groups any more. Higher suPAR levels in recipients one year after KTx were associated with a more severe eGFR loss in the following three years in multivariable cox-regression (n = 82, p = 0.021). suPAR-levels above 6212 pg/ml one year after KTx are associated with eGFR loss > 30%, which occurred almost twice as fast as in patients with suPAR ≤ 6212 pg/ml (p < 0.001). Hence, suPAR level at one year mark might be a risk indicator of increased eGFR loss.

description: We study the structural and thermodynamic properties of bilayer graphene, a prototype two-layer membrane, by means of Monte Carlo simulations based on the empirical bond order potential LCBOPII. We present the temperature dependence of lattice parameter, bending rigidity and high temperature heat capacity as well as the correlation function of out-of-plane atomic displacements. The thermal expansion coefficient changes sign from negative to positive above $\approx 400$ K, which is lower than previously found for single layer graphene and close to the experimental value of bulk graphite. The bending rigidity is twice as large than for single layer graphene, making the out-of-plane fluctuations smaller. The crossover from correlated to uncorrelated out-of-plane fluctuations of the two carbon planes occurs for wavevectors shorter than $\approx 3$ nm$^{-1}$

title: Symmetry analysis of hydrodynamic-type systems

Publisher: name: Memorial University of Newfoundland

description: Using advantages of nonstandard computational techniques based on the light-cone variables, we explicitly find the algebra of generalized symmetries of the (1+1)-dimensional Klein{Gordon equation. This allows us to describe this algebra in terms of the universal enveloping algebra of the essential Lie invariance algebra of the Klein{Gordon equation. Then we single out variational symmetries of the corresponding Lagrangian and compute the space of local conservation laws of this equation, which turns out to be generated, up to the action of generalized symmetries, by a single first-order conservation law. We study the hydrodynamic-type system of differential equations modeling isothermal no-slip drift ux. Using the facts that the system is partially coupled and its essential subsystem reduces to the (1+1)-dimensional Klein{Gordon equation, we exhaustively describe generalized symmetries, cosymmetries and local conservation laws of this system. A generating set of local conservation laws under the action of generalized symmetries is proved to consist of two zeroth-order conservation laws. The subspace of translationinvariant conservation laws is singled out from the entire space of local conservation laws. The essential subsystem possesses three first-order hydrodynamic-type Hamiltonian operators, two of which are prolonged nonlocally to the entire system. The (1+2)-dimensional hydrodynamic-type system governing the shallow water model is studied from the symmetry-analysis point of view. Its complete point symmetry group is found with the help of the automorphism-based algebraic method. Lie reductions of both codimensions one and two are classified. We exhaustively describe the algebra of differential invariants of the point symmetry group of the system using the method of moving frames. We construct for the first time classes of differential equations with nontrivial generalized equivalence groups, i.e. whose equivalence-transformation components corresponding to independent and dependent variables locally depend on nonconstant arbitrary elements of the class. We rigourously construct extended generalized equivalence groups of several classes of differential equations as well. The new notion of effective generalized equivalence group is introduced.

description: We study the infrared (long distance) behavior of the free photon field in de Sitter spacetime. Using a two-parameter family of gauge fixing terms, we show that the infrared (IR) behavior of the two-point function is highly gauge-dependent and ranges from vanishing to growing. This situation is in disagreement with its counterpart in flat spacetime, where the two-point function vanishes in the IR for any choice of the gauge fixing parameters. A criterion to isolate the "physical" part of the two-point function is given and is shown to lead to a well-behaved two-point function in the IR.

description: Bildverarbeitungssysteme werden in zunehmendem Maße für Aufgaben der Automatisierungstechnik und im besonderen in der Qualitätssicherung erfolgreich eingesetzt. Zur Lösung komplexer oder zeitkritischer Erkennungsaufgaben, wie z.B. in der Oberflächeninspektion und Texturanalyse, ist der Einsatz rechenintensiver Algorithmik erforderlich, so daß eine Softwarerealisierung nicht oder nur in speziellen Fällen möglich ist. Der vorliegende Beitrag zeigt Ansatzpunkte und Methoden zur Auslegung von Softwaresystemen zur Qualitätssicherung in Echtzeit am Beispiel der Inspektion texturierter Oberflächen auf Es werden merkmalsbasierte Verfahren diskutiert, wobei die ganzheitliche und zielorientierte Berücksichtigung aller Verfahrensschritte wesentlich ist. Zur Unterstützung des Designs von Bildverarbeitungslösungen werden automatische Verfahren der Systemkonfigurierung vorgestellt.

description: We present the results of a site characterization study carried out at the Astronomical Observatory of the Autonomous Region of the Aosta Valley (OAVdA), in the Western Italian Alps, aimed at establishing its potential to host a photometric transit search for small-size planets around a statistically significant sample of nearby cool M dwarfs. [abridged] we gauged site-dependent observing conditions such as night-sky brightness, photometric precision, and seeing properties. Public meteorological data were also used in order to help in the determination of the actual number of useful observing nights per year. The measured zenithal $V$-band night-sky brightness is typical of that of very good, very dark observing sites. The extinction registered at $V$ band is not dissimilar from that of other sites. The median seeing over the period of in situ observations is found to be $\sim1.7^{\prime\prime}$. Given the limited duration of the observations, we did not probe any possible seeing seasonal patterns, or the details of its possible dependence on other meteorological parameters, such as wind speed and direction. Moreover, our data show that the seeing at the observatory was reasonably stable during most of the nights. The fraction of fully clear nights per year amounts to 39\%, while the total of useful nights increases to 57\% assuming a (conservative) cloud cover of not more than 50\% of the night. Based on the analysis of photometric data collected over the period May-August 2009 for three stellar fields centered on the transiting planet hosts WASP-3, HAT-P-7, and Gliese 436, we achieve seeing-independent best-case photometric precision $σ_\mathrm{ph}\lesssim3$ mmag (rms) in several nights for bright stars ($R\lesssim 11$ mag). A median performance $σ_\mathrm{ph}\sim6$ mmag during the observing period is obtained for stars with $R\lesssim13$ mag. [abridged]

description: The significant contributions of resource sectors to national economies are well known; however, information on sub-national impacts is much scarcer. Using Chile as a case study, this paper investigates how disturbances in the price of copper impact the economies where this mineral is produced. The proposed method combines estimates of long-term copper prices with a general equilibrium model to simulate the differential effects of copper price variations. The results suggest that price variations affect the design and implementation of public and private policies, at economic and business levels.

description: We analyze the dynamic interaction of mission-oriented R&D expenditure stocks with domestic and foreign private and public R&D, total-factor-productivity (TFP), and gross domestic product (GDP) for seven EU countries. We use the vector-error-correction method. Permanent changes on mission-oriented R&D increase total-factor-productivity and GDP. On average across periods and countries, a 1% increase of mission-oriented R&D leads to an additional 0.485% public R&D, 0.705% private R&D, 0.485% for TFP, and 0.56% GDP. We also show years of positive gains, the sums of discounted net present values, and the average yearly gains/GDP ratio. Mission-oriented R&D has high internal rates of return.

description: We report synthesis, structural, magnetic, specific heat and Density Functional Theory (DFT) studies on MgCNi3 superconductor. Polycrystalline MgCNi3 samples are synthesized through standard solid state reaction route and found to crystallize in cubic perovskite structure with space group Pm3m, without any detectable trace of Ni impurity. Both AC and DC magnetization exhibited superconducting transition (Tc) at around 7.25 K. The lower critical field (Hc1) and irreversibility field (Hirr) are around 140 Oe and 11 kOe respectively at 2 K. The upper critical field (Hc2) being determined from in-field AC susceptibility measurements is 11.6 kOe and 91.70 kOe with 50% and 90% diamagnetism criteria respectively. Heat capacity (Cp) measurements are carried out under applied field of up to 140 kOe and down to 2 K. The Sommerfeld constant (γ) and Debye temperature (ΘD) as determined from low temperature fitting of Cp(T) data to Sommerfeld-Debye model are 36.13 mJ/mole-K2 and 263.13 K respectively. The Bardeen-Cooper-Schrieffer (BCS) parameter (2Δ/KBTc) is around 3.62, suggesting MgCNi3 to be an intermediate coupled BCS superconductor with value λ = 0.69. Although the density functional theory (DFT) calculations exhibited the compound to be non-magnetic but with spin fluctuations, the experimental isothermal magnetization MH loops at 20, 50, 100, 200 and 300 K showed some ferromagnetic nature in this compound with coercive field (Hc) of around 50 Oe at 20 K. The Ni3d states play dominant roles near the Fermi levels and there is strong hybridization between Ni3d and C2p states. It seems that MgCNi3 is superconducting in close proximity of ferromagnetism.

description: Ageratina adenophora is an invasive plant of global importance and has a broad distribution in the Western Himalayas. Endophtytic fungus Coniochaeta sp.F-8 was found in Ageratina adenophora. In this paper, we aim to investigate the antioxidative activity and cytotoxicity of the metabolites from Coniochaeta sp.F-8. Consequently, two compounds Phomoxanthone A and Penialidin A were isolated from the endophytic fungus of Ageratina adenophora for the first time. The structures of compounds were identified by IR, NMR and ESI-MS methods. Moreover, both of those compounds showed considerable antioxidative activity in vitro and resulted cytotoxicity in mouse embryo fibroblasts cell line Balb/c3T3. The present study provides a theoretical foundation for the development and utilization of endophytic fungi in Ageratina adenophora as a medicinal substance.

description: Recent experiments have confirmed the importance of nuclear quantum effects even in large biomolecules at physiological temperature. Here we describe how the path integral formalism can be used to describe rigorously the nuclear quantum effects on equilibrium and kinetic properties of molecules. Specifically, we explain how path integrals can be employed to evaluate the equilibrium (EIE) and kinetic (KIE) isotope effects, and the temperature dependence of the rate constant. The methodology is applied to the [1,5] sigmatropic hydrogen shift in pentadiene. Both the KIE and the temperature dependence of the rate constant confirm the importance of tunneling and other nuclear quantum effects as well as of the anharmonicity of the potential energy surface. Moreover, previous results on the KIE were improved by using a combination of a high level electronic structure calculation within the harmonic approximation with a path integral anharmonicity correction using a lower level method.

Manuale di sopravvivenza. Quando si esce dal nido

description: C’è un periodo della vita in cui tutte le sicurezze vengono a mancare, un momento in cui è necessario prendere in mano la propria vita e diventare persone responsabili. Bisogna staccarsi dai propri genitori, dalle abitudini e dagli amici per intraprendere una nuova avventura: andare a vivere da soli. Il target preso in considerazione è quello di giovani ragazzi tra i diciotto e i ventun anni che stanno per compiere il grande passo. Saranno pronti ad affrontare tutte le insidie che si trovano nascoste dietro alla gestione di un appartamento? Da questa domanda nasce la volontà di aiutare i miei coetanei a lanciarsi in questa nuova impresa grazie all’aiuto di un manuale di sopravvivenza ricco di trucchi e consigli. La fase di ricerca si concentra principalmente su colloqui verbali e raccolte di testimonianze di ragazzi che rientrano nel mio target. Tramite queste interviste ho potuto selezionare gli aspetti più critici e difficoltosi della vita al di fuori di casa. Questi sono stati tramutati in illustrazioni e semplificati in modo da rendere tutto molto piacevole e leggero alla lettura. I disegni sono stilisticamente coerenti in quanto tutti proposti in bianco e nero e realizzati usando lo stesso linguaggio. Il manuale si presenta con un indice suddiviso in quattro capitoli principali: cucina, pulizia, convivenza e sicurezza; ogni sezione è distinta dalle altre grazie l’uso di carte differenti per facilitarne la ricerca e l’uso. Attraverso delle illustrazioni essi mostrano vari stratagemmi utili e pratici per andare a vivere da soli. L’argomento si presenta quindi in maniera leggera e con un pizzico d’ironia. Il manuale è accompagnato da contenuti aggiuntivi che sono presenti nell’ultima pagina. Questi ultimi servono per semplificare le fasi decisionali e organizzative all’interno dell’appartamento. Ho realizzato dunque un manuale di sopravvivenza per quando si esce dal nido.
