description: We present a multi-wavelength investigation of a C-class flaring activity that occurred in the active region NOAA 12734 on 8 March 2019. The investigation utilises data from AIA and HMI on board the SDO and the Udaipur-CALLISTO solar radio spectrograph of the Physical Research Laboratory. This low intensity C1.3 event is characterised by typical features of a long duration event (LDE), viz. extended flare arcade, large-scale two-ribbon structures and twin coronal dimmings. The eruptive event occurred in a coronal sigmoid and displayed two distinct stages of energy release, manifested in terms of temporal and spatial evolution. The formation of twin dimming regions are consistent with the eruption of a large flux rope with footpoints lying in the western and eastern edges of the coronal sigmoid. The metric radio observations obtained from Udaipur-CALLISTO reveals a broad-band ($\approx$50-180 MHz), stationary plasma emission for $\approx$7 min during the second stage of the flaring activity that resemble a type IV radio burst. A type III decametre-hectometre radio bursts with starting frequency of $\approx$2.5 MHz precedes the stationary type IV burst observed by Udaipur-CALLISTO by $\approx$5 min. The synthesis of multi-wavelength observations and Non-Linear Force Free Field (NLFFF) coronal modelling together with magnetic decay index analysis suggests that the sigmoid flux rope underwent a zipping-like uprooting from its western to eastern footpoints in response to the overlying asymmetric magnetic field confinement. The asymmetrical eruption of the flux rope also accounts for the observed large-scale structures viz. apparent eastward shift of flare ribbons and post flare loops along the polarity inversion line (PIL), and provides an evidence for lateral progression of magnetic reconnection site as the eruption proceeds.

description: Drops deposited on rough and hydrophobic surfaces can stay suspended with gas pockets underneath the liquid, then showing very low hydrodynamic resistance. When this superhydrophobic state breaks down, the subsequent wetting process can show different dynamical properties. A suitable choice of the geometry can make the wetting front propagate in a stepwise manner leading to {\it square-shaped} wetted area: the front propagation is slow and the patterned surface fills by rows through a {\it zipping} mechanism. The multiple time scale scenario of this wetting process is experimentally characterized and compared to numerical simulations.

Hardware in the loop (HIL) simulation is a computer simulation that has the ability to simulate UAV flight characteristic, sensor modeling and actuator modeling while communicating in real time with the UAV autopilot hardware. HIL simulation can be used to test the UAV autopilot hardware reliability, test the closed loop performance of the overall system and tuning the control parameter. By rigorous testing in the HIL simulator, the risk in the field trial can be minimized.

title: In silico modelling of in-host tuberculosis dynamics : towards building the virtual patient
Creators: name: Pitcher, Michael John
Publisher: name: University of St Andrews
Year: 2020

description: Tuberculosis (TB) accounts for over 1 million deaths each year, despite effective treatment regimens being available. Improving the treatment of TB will require new regimens, each of which will need to be put through expensive and lengthy clinical trials, with no guarantee of success. The ability to predict which of many novel regimens to progress through the clinical trial stages would be an important tool to TB research. as current models are constrained in their ability to reflect the whole spectrum of pathophysiology, particularly as there remains uncertainty around the events that occur. This thesis explores the use of computational techniques to model a pulmonary human TB infection. We introduce the first in silico model of TB occurring over the whole lung that incorporates both the environmental heterogeneity that is exhibited within different spatial regions of the organ, and the different bacterial dissemination routes, in order to understand how bacteria move during infection and why post-primary disease is typically localised towards the apices of the lung. Our results show that including environmental heterogeneity within the lung can have profound effects on the results of an infection, by creating a region towards the apex which is preferential for bacterial proliferation. We also present a further iteration of the model, whereby the environment is made more granular to better understand the regions which are afflicted during infection, and show how sensitivity analysis can determine the factors that contribute most to disease outcomes. We show that in order to simulate TB disease within a human lung with sufficient accuracy, better understanding of the dynamics is required. The model presented in this thesis is intended to provide insight into these complicated dynamics, and thus make progress towards an end goal of a virtual clinical trial, consisting of a heterogeneous population of synthetic virtual patients.

description: Using Sloan Digital Sky Survey Data Release 5, we have investigated the intrinsic axis ratio distribution (ARD) for early-type galaxies. We have constructed a volume-limited sample of 3,922 visually-inspected early-type galaxies at $0.05 \leq z \leq 0.06$ carefully considering sampling biases caused by the galaxy isophotal size and luminosity. We attempt to de-project the observed ARD into three-dimensional types (oblate, prolate, and triaxial), which are classified in terms of triaxiality. We confirm that no linear combination of $randomly$-distributed axis ratios of the three types can reproduce the observed ARD. However, using Gaussian intrinsic distributions, we have found reasonable fits to the data with preferred mean axis ratios for oblate, prolate, and triaxial (triaxials in two axis ratios), $μ_o=0.44, μ_p=0.72, μ_{t,β}=0.92, μ_{t,γ}=0.78$ where the fractions of oblate, prolate and triaxial types are \textrm{O:P:T}=0.29^{\pm0.09}:0.26^{\pm0.11}:0.45^{\pm0.13}$. We have also found that the luminous sample ($-23.3 < M_r \leq -21.2$) tends to have more triaxials than the less luminous ($-21.2 < M_r

description: A unified theoretical model reproducing charge radii of known atomic nuclei plays an essential role in making extrapolations for unknown nuclei. Recently developed new ansatz which phenomenologically takes into account the neutron-proton short-range correlations ($np$-SRCs) can describe the discontinuity properties and odd-even staggering (OES) effect of charge radii along isotopic chains remarkably well. In this work, we further review the modified root-mean-square (rms) charge radii formula in the framework of relativistic mean field (RMF) theory. The charge radii are calculated along various isotopic chains that include the nuclei featuring the $N=50$ and $82$ magic shells. Our results suggest that RMF with and without considering a correction term give an almost similar trend of nuclear size for some isotopic chains with open proton shell, especially the abrupt increases across the strong neutron closed shells and the OES behaviors. This reflects that the $np$-SRCs have almost no influence for some nuclei due to the strong coupling between different levels around Fermi surface. The weakening OES behavior of nuclear charge radii is observed generally at completely filled neutron shells and this may be proposed as a signature of magic indicator.

description: In this work we aim to characterise the dust motion in the inner coma of comet 67P/Churyumov- Gerasimenko to provide constraints for theoretical 3D coma models. The OSIRIS camera onboard the Rosetta mission was able for the first time to acquire images of single dust particles from inside the cometary coma, very close to the nucleus. We analyse a large number of particles, performing a significant statistic of their behaviour during the post perihelion period, when the spacecraft covered distances from the nucleus ranging between 80 and 400 km. We describe the particle trajectories, investigating their orientation and finding highly radial motion with respect to the nucleus. Then, from the particle brightness profiles, we derive a particle rotational frequency of v < 3.6 Hz, revealing that they are slow rotators and do not undergo fragmentation. We use scattering models to compare the observed spectral radiance of the particles with the simulated ones in order to estimate their size, finding values that range from millimetres up to centimetres. The statistics performed in this paper provide useful parameters to constrain the cometary coma dynamical models.

Some properties of such domain walls in motion are discussed here, for example the ability of negative-tension domain walls to bounce off spacetime singularities and the consequences for cosmological perturbations. In this context, we will also review a colliding branes solution of heterotic M-theory that has been proposed as a model for early universe cosmology.

description: The WorldWide Web is one of the most important communication systems we use in our everyday life. Despite its central role, the growth and the development of the WWW is not controlled by any central authority. This situation has created a huge ensemble of connections whose complexity can be fruitfully described and quantified by network theory. One important application that allows to sort out the information present in these connections is given by the PageRank alghorithm. Computation of this quantity is usually made iteratively with a large use of computational time. In this paper we show that the PageRank can be expressed in terms of a wave function obeying a Schroedinger-like equation. In particular the topological disorder given by the unbalance of outgoing and ingoing links between pages, induces wave function and potential structuring. This allows to directly localize the pages with the largest score. Through this new representation we can now compute the PageRank without iterative techniques. For most of the cases of interest our method is faster than the original one. Our results also clarify the role of topology in the diffusion of information within complex networks. The whole approach opens the possibility to novel techniques inspired by quantum physics for the analysis of the WWW properties.

A blind child's meaning for look : a replication of Landau & Gleitman
Creators: name: Murphy, Cynthia Maureen
Publisher: name: University of British Columbia
Year: 2010

description: Landau and Gleitman's experiments investigating a blind child's meaning for look, as it applied to herself, were replicated with a three year old boy who was totally blind, and had no concomitant disorders. Several commands to look were presented within informal play sessions. Responses to the look commands were compared with responses to instructions to touch, listen and taste. Experiments were video recorded for subsequent analysis. It was found that the blind child associated the haptic perceptual modality with the visual verb, in that an instruction to look at an object elicited manual exploration of the object. His meaning for look was distinct from his meanings for the other perceptual verbs. These findings were consistent with Landau and Gleitman's findings. Landau and Gleitman's interpretation, of how a blind child's mastery of visual terms bears on the word/meaning mapping problem, is critically discussed.

description: In this paper we investigate the spin-resolved thermoelectric properties of strongly correlated molecular junctions in the linear response regime. The magnetic molecule is modeled by a single orbital level to which the molecular core spin is attached by an exchange interaction. Using the numerical renormalization group method we analyze the behavior of the (spin) Seebeck effect, heat conductance and figure of merit for different model parameters of the molecule. We show that the thermopower strongly depends on the strength and type of the exchange interaction as well as the molecule's magnetic anisotropy. When the molecule is coupled to ferromagnetic leads, the thermoelectric properties reveal an interplay between the spin-resolved tunneling processes and intrinsic magnetic properties of the molecule. Moreover, in the case of finite spin accumulation in the leads, the system exhibits the spin Seebeck effect. We demonstrate that a considerable spin Seebeck effect can develop when the molecule exhibits an easy-plane magnetic anisotropy, while the sign of the spin thermopower depends on the type and magnitude of the molecule's exchange interaction.

description: This paper presents a systematic and accurate treatment of the evolution of cosmological perturbations in self-interacting dark matter models, for particles which decoupled from the primordial plasma while relativistic. We provide a numerical implementation of the Boltzmann hierarchies developed in a previous paper [JCAP, 09 (2020) 041] in a publicly available Boltzmann code and show how it can be applied to realistic DM candidates such as sterile neutrinos either under resonant or non-resonant production mechanisms, and for different field mediators. At difference with traditional fluid approximations -- also known as a $c_{\rm eff}-c_{\rm vis}$ parametrizations -- our approach follows the evolution of phase-space perturbations under elastic DM interactions for a wide range of interaction models, including the effects of late kinetic decoupling. Finally, we analyze the imprints left by different self interacting models on linear structure formation, which can be constrained using Lyman-$α$ forest and satellite counts. We find new lower bounds on the particle mass that are less restrictive than previous constraints.

Local asymptotic normality for finite dimensional quantum systems

Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We extend our previous results on local asymptotic normality (LAN) for qubits, to quantum systems of arbitrary finite dimension $d$. LAN means that the quantum statistical model consisting of $n$ identically prepared $d$-dimensional systems with joint state $ρ^{\otimes n}$ converges as $n\to\infty$ to a statistical model consisting of classical and quantum Gaussian variables with fixed and known covariance matrix, and unknown means related to the parameters of the density matrix $ρ$. Remarkably, the limit model splits into a product of a classical Gaussian with mean equal to the diagonal parameters, and independent harmonic oscillators prepared in thermal equilibrium states displaced by an amount proportional to the off-diagonal elements. As in the qubits case, LAN is the main ingredient in devising a general two step adaptive procedure for the optimal estimation of completely unknown $d$-dimensional quantum states. This measurement strategy shall be described in a forthcoming paper.

description: We implement a standard Monte Carlo algorithm to study the slow, equilibrium dynamics of a silica melt in a wide temperature regime, from 6100 K down to 2750 K. We find that the average dynamical behaviour of the system is in quantitative agreement with results obtained from molecular dynamics simulations, at least in the long-time regime corresponding to the alpha-relaxation. By contrast, the strong thermal vibrations related to the Boson peak present at short times in molecular dynamics are efficiently suppressed by the Monte Carlo algorithm. This allows us to reconsider silica dynamics in the context of mode-coupling theory, because several shortcomings of the theory were previously attributed to thermal vibrations. A mode-coupling theory analysis of our data is qualitatively correct, but quantitative tests of the theory fail, raising doubts about the very existence of an avoided singularity in this system. We discuss the emergence of dynamic heterogeneity and report detailed measurements of a decoupling between translational diffusion and structural relaxation, and of a growing four-point dynamic susceptibility. Dynamic heterogeneity appears to be less pronounced than in more fragile glass-forming models, but not of a qualitatively different nature.

description: We present an analytic approximate seismic inversion scheme for damped transverse coronal loop oscillations based on the thin tube and thin boundary approximation for computing the period and the damping time. Asymptotic expressions for the period and damping rate are used to illustrate the process of seismological inversion in a simple and easy to follow manner. The inversion procedure is formulated in terms of two simple functions, which are given by simple closed expressions. The analytic seismic inversion shows that an infinite amount of 1-dimensional equilibrium models can reproduce the observed periods and damping times. It predicts a specific range of allowable values for the Alfven travel time and lower bounds for the density contrast and the inhomogeneity length scale. When the results of the present analytic seismic inversion are compared with those of a previous numerical inversion, excellent agreement is found up to the point that the analytic seismic inversion emerges as a tool for validating results of numerical inversions. Actually it helped us to identify and correct inaccuracies in a previous numerical investigation.

title: Synthese und Charakterisierung eindimensionaler metalloxidischer Nanostrukturen für elektrochemische Katalyse und Sensorik
Creators: name: Antoni, Markus
Publisher: name: UNSPECIFIED
Year: 2021

description: Metallische Nanostrukturen sind bekannt für ihre außerordentlichen katalytischen Eigenschaften und ziehen daher große Aufmerksamkeit in der zeitgenössischen Forschung auf sich. In der letzten Zeit stieg auch das Interesse an oxidischen Nanoobjekten aufgrund ihrer bemerkenswerten Eigenschaften nicht nur im Bereich der Katalyse. Da Oxide bereits in oxidierter Form vorliegen, sind sie im Vergleich zu Metallen weniger anfällig für Phänomene wie Korrosion. Bei den meisten Oxiden handelt es sich um Halbleiter oder Isolatoren. Besonders die halbleitenden Eigenschaften bieten die Möglichkeit die Materialien als Photokatalysatoren, Solarzellen und Gassensoren einzusetzen. Nanoobjekte stechen durch ihr besonders großes Oberflächen-zu-Volumen-Verhältnis heraus, was sie besonders für katalytische und sensorische Anwendungen geeignet erscheinen lässt. Der Vorteil von eindimensionalen Nanoobjekten besteht in der erhöhten Stabilität, der geringeren Neigung zur Agglomeration und dem damit einhergehenden geringeren Verlust an aktiver Oberfläche, weswegen diese Strukturen auch als Support-Struktur anderer aktiver Objekte eingesetzt werden können. Aus diesen Gründen beschäftigt sich die vorliegende Arbeit mit der Untersuchung von Möglichkeiten metalloxidische eindimensionale Nanoojekte nasschemisch herzustellen. Die Templatsynthese wird als geeignetes Werkzeug für die Herstellung betrachtet. Ein formgebendes poröses Templat wird mit dem Zielmaterial ausgefüllt oder ausgekleidet, um auf diese Weise Nanodrähte bzw. -röhren zu erlangen. Elektrodeposition und stromlose Abscheidung in ionenspurgeätzten Kunstofffolien bewähren sich als Herstellungsverfahren. An dieser Stelle kann zwischen direkten und indirekten Verfahren unterschieden werden. Indirekte Verfahren beinhalten mindestens zwei Prozessschritte, wie z.B. Abscheidung und Nachbehandlung. Die Nachbehandlung findet in Form von thermischer oder Plasmabehandlung statt. Direkte Verfahren führen direkt zu den gewünschten Strukturen. In diesem Bereich werden stromlose Abscheidung, sowie anodische und kathodische Elektrodeposition eingesetzt. Die direkten Methoden bieten den Vorteil, dass auf die belastenden Nachbehandlungen verzichtet werden kann. Diese Arbeit beleuchtet die Unterschiede, Vorteile und Nachteile der verschiedenen Methoden um oxidische Nanostrukturen herzustellen. Diese werden auf Basis von Cer, Kobalt, Mangan, Nickel, Titan, Zink und Zinn hergestellt. Zusätzlich hebt die vorliegende Arbeit den Nutzen der hergestellten Strukturen hervor, indem Beispiele für Anwendungsgebiete, die von Brennstoffzellenkatalyse über elektrochemische Sensorik bis hin zur Gassensorik reichen, ausgearbeitet werden.

description: Bug localization is an important aspect of software maintenance because it can locate modules that should be changed to fix a specific bug. Our previous study showed that the accuracy of the information retrieval (IR)-based bug localization technique improved when used in combination with code smell information. Although this technique showed promise, the study showed limited usefulness because of the small number of: 1) projects in the dataset, 2) types of smell information, and 3) baseline bug localization techniques used for assessment. This paper presents an extension of our previous experiments on Bench4BL, the largest bug localization benchmark dataset available for bug localization. In addition, we generalized the smell-aware bug localization technique to allow different configurations of smell information, which were combined with various bug localization techniques. Our results confirmed that our technique can improve the performance of IR-based bug localization techniques for the class level even when large datasets are processed. Furthermore, because of the optimized configuration of the smell information, our technique can enhance the performance of most state-of-the-art bug localization techniques.

Sensitivity and computation of a defective eigenvalue

description: A defective eigenvalue is well documented to be hypersensitive to data perturbations and round-off? errors, making it a formidable challenge in numerical computation particularly when the matrix is known through approximate data. This paper establishes a finitely bounded sensitivity of a defective eigenvalue with respect to perturbations that preserve the geometric multiplicity and the smallest Jordan block size. Based on this perturbation theory, numerical computation of a defective eigenvalue is regularized as a well-posed least squares problem so that it can be accurately carried out using floating point arithmetic even if the matrix is perturbed.

We suggest an alternative generalization, namely to problems of finding hidden nonlinear structures over finite fields. We give examples of two such problems that can be solved efficiently by a quantum computer, but not by a classical computer. We also give some positive results on the quantum query complexity of finding hidden nonlinear structures.

description: It is well-known that the C/N ratio of plant residues can influence soil nutrient availability, but the effect of repeated addition of plant residues with different C/N ratio is less explored. In previous studies, we showed that nutrient availability and soil respiration after the second residue addition is influenced not only by the C/N ratio of that residue, but also by the C/N ratio of the previously added residue. These experiments were carried out without plants and it was unclear how the legacy effect would influence plant growth and nutrient uptake. The aim of this experiment was to assess plant growth, nutrient uptake and soil nutrient availability after the second residue addition with different length of time between the first and second residue addition where the first and second residue had the same or a different C/N ratio. High (H) or low C/N (L) residue was added at the start of the experiment, the second residue with either the same or a different C/N ratio was added on days 7, 14, 21 or 28 with a total residue addition of 20 g kg-1 giving four residue treatments: HH, LL, LH and HL. Wheat was planted immediately after the second residue addition and grown for 28 days. N and P availability were measured on days 7, 14, 21 and 28 and at plant harvest.

description: The Neil Gehrels Swift observatory observe Gamma-Ray bursts (GRBs) plateaus in X-rays. We test the reliability of the closure relations through the fireball model when dealing with the GRB plateau emission. We analyze 455 X-ray lightcurves (LCs) collected by \emph{Swift} from 2005 (January) until 2019 (August) for which the redshift is both known and unknown using the phenomenological Willingale 2007 model. Using these fits, we analyze the emission mechanisms and astrophysical environments of these GRBs through the closure relations within the time interval of the plateau emission. Finally, we test the 3D fundamental plane relation (Dainotti relation) which connects the prompt peak luminosity, the time at the end of the plateau (rest-frame), and the luminosity at that time, on the GRBs with redshift, concerning groups determined by the closure relations. This allows us to check if the intrinsic scatter σ_{int} of any of these groups is reduced compared to previous literature. The most fulfilled environments for the electron spectral distribution, p>2, are Wind Slow Cooling (SC) and ISM Slow Cooling for cases in which the parameter q, which indicates the flatness of the plateau emission and accounts for the energy injection, is =0 and =0.5, respectively, both in the cases with known and unknown redshifts. We also find that for the sGRBs All ISM Environments with $q=0$ have the smallest σ_{int}=0.04 \pm 0.15 in terms of the fundamental plane relation holding a probability of occurring by chance of p=0.005. We have shown that the majority of GRBs presenting the plateau emission fulfil the closure relations, including the energy injection, with a particular preference for the Wind SC environment. The subsample of GRBs that fulfil given relations can be used as possible standard candles and can suggest a way to reduce the intrinsic scatter of these studied relationships.

Should justice for people come before justice for the environment? Engaging students in debates about environmental justice.
Creators: name: Kopnina, Helen
Publisher: name: Università degli Studi di Torino
Year: 2018

description: This paper outlines the main differences between ecocentric and anthropocentric positions in regard to justice, exploring university students’ perceptions of the concepts of social and ecological justice and reflecting on how values assigned to humans and the environment are balanced and contested. Putting justice for people before the environment is based on evidence that biological conservation can disadvantage local communities; the idea that the very notion of justice is framed by humans and therefore remains a human issue; and the assumption that humans have a higher value than other species. Putting justice for the environment first assumes that only an ecocentric ethic guarantees protection of all species, including humans, and therefore ecological justice already guarantees social justice. This research shows that many students emphasize the convergence of social and ecological justice where human and environmental interests correspond. While not wishing to diminish the underlying assumptions of either ethical orientation, the common “enemy” of both vulnerable communities and nonhuman nature, as identified by students, is an ideology of economic growth and industrial development.

Year: 2018

description: The Anthropocene Media Project is an on-going research project on how the Anthropocene (the geological concept created to measure and name human impacts on the Earth System) is represented in the mass media in local languages all over the world. So far, data has been collected from online searches of newspapers, magazines and other news media websites from around 100 countries/regions by about 50 volunteer researchers. The data is being analyzed by years of publication, numbers and types of articles. The paper concludes with some observations on the role and responsibility of the mass media in interpreting science for various publics.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We introduce a non-linear frequency dependent D+1 terminal conductance that characterizes a D dimensional Fermi gas, generalizing the Landauer conductance in D=1. For a 2D ballistic conductor we show that this conductance is quantized and probes the Euler characteristic of the Fermi sea. We critically address the roles of electrical contacts and of Fermi liquid interactions, and we propose experiments on 2D Dirac materials such as graphene using a triple point contact geometry.

description: What is at stake for scientists when communicating ecology? This is the basic question tackled in this paper, that we explored through reflections about an initiative of informal communication of ecological research called “Cammini LTER”: itineraries connecting a number of sites belonging to the Italian Long-Term Ecological Research network (LTER-Italy). LTER-Italy ecologists walked and cycled together with citizens creating a physical and visible movement of researchers ‘towards’ and ‘with’ citizens, aiming at providing the public with the opportunity to get familiar with Italian ecosystems, from the sea to alpine tundra. We address here the debates and the critical considerations among researchers themselves, stimulated by the overall experience, with focus on some relevant issues pertaining science communication, and even research production, evidencing the need for a cultural shift, which go far beyond the national context and the LTER – Italy network. Using a participant observations approach, through researchers’ words used to describe - formally and informally - the experience, we report and comment here the main narratives emerged, showing different attitudes of LTER researchers in Cammini towards the society and the role of ecology in it. Relationship and knowledge exchange appear crucial for communicating ecology, which can thus become an opportunity for building new qualities of knowledge and for creating a shared civic culture, able to make all players feel mutual responsible and contribute to the solution of particular socio-ecological challenges.

The Contribution of the Capability Approach to the Understanding of Young People’s Sustainability Engagement as a Positive Developmental Outcome.
Creators: name: Rossi, Giulia

Publisher: name: Università degli Studi di Torino
Year: 2018

description: Young people’s engagement with sustainability includes both civic and pro environmental behaviors (e.g. environmental activism) that contribute to the development of sustainable communities. It reflects a holistic idea of sustainability, where civic democracy and ecological integrity are strictly interconnected. The lack of empirical studies exploring this kind of engagement among young people may well be a consequence of the lack in the literature of a shared theoretical model that provides a framework for both types of behaviors. By integrating Positive Youth Development with the Capability Approach, the aim of this paper is to provide new theoretical input as a way of filling this gap. The proposed model is based on the idea that both positive individual and sustainable development are a question of social justice that takes place within specific domains and is related to understanding experience within life courses.

Key words: Positive Youth Development; Capability Approach; Young people; Engagement; Sustainability

description: This project, conducted with Classical High School students, was developed under the "Alternating School and Work Experience" program (Italian Law n. 107/2015) between the "G. Palmieri" High School of Lecce and the Environmental Protection Agency of Puglia (ARPA), Department of Lecce, in Italy. In particular, this paper describes the “HABs’ world” allegorically, in terms of one of the most famous examples of Italian literature, the Divine Comedy. Harmful algal blooms, or HABs, occur when colonies of algae, simple photosynthetic organisms that live in the sea and freshwater, grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. Since HABs can be defined as “bad”, based on their negative characteristics, some of these were compared to the sinful souls that Dante and Virgil encountered along their journey into Hell. It is argued that such integration of literary and scientific contexts in terms of ecological indicators helps students understand the relationship between the sustainability of human and environmental trajectories.
