description: Within a backdrop of rising drug use in Kenya, this thesis applies the
      social ecology theory to elaborate the determinants of drug use
      trajectories and attendant HIV risks among women who inject drugs. This
      thesis comprises four parts. The first part is an overview of the
      epidemiology of injecting drug use. The second part is a literature review
      exploring 1) conceptualisation, 2) health impacts, and 3) determinants of
      drug-use trajectories. Based on a synthesis of 142 sources from four
      databases, literature suggests that the main phases of drug use consist of
      initiation, transition to injecting, and chronic addicted injecting.
      Additionally, drug use has significant negative impacts on the health of
      injectors. Although prior research has explored and identified micro- and
      macro-level determinants of injecting drug use, trajectory studies among
      women, particularly in sub-Saharan Africa, are rare. Based on this gap,
      the third part of this thesis explores determinants of drug use
      trajectories and HIV risks among 45 women, using secondary analysis of
      qualitative data. This study found that initiations, transitions, and
      chronic drug injecting, and the attendant HIV risks were not determined by
      a single factor but by multiple and intersecting social-ecological
      determinants located at the individual, interpersonal and
      societal-structural levels. By employing the social ecology theory, the
      importance of joblessness, gender inequity, economics, drug availability,
      and health systems in shaping trajectories and HIV risks was identified.
      The fourth part discusses these findings, and demonstrates that this study
      contributes to an empirical understanding of women’s drug use trajectories
      and HIV risks, advances scarce literature relating to qualitative
      secondary data analysis, and identifies the need to place
      intersectionality central to the future application of the social ecology
      theory. To limit women’s drug-injecting and attendant HIV risks, it is
      essential to focus on upstream social-structural determinants, alongside
      the currently emphasised individual and interpersonal determinants.

L’oggettivizzazione del processo amministrativo, tra tendenze legislative e interpretazioni giurisprudenziali.

Year: 2020

description: Il lavoro esamina in modo critico alcune disposizioni normative ed alcuni orientamenti giurisprudenziali da cui emerge una certa tendenza all’oggettivizzazione del processo amministrativo. Quest’ultimo, in una serie di ipotesi non trascurabili per numero e rilevanza, appare finalizzato a tutelare non soltanto gli interessi individuali (è fuori discussione che la giurisdizione amministrativa sia «di diritto soggettivo», cioè deputata alla tutela di situazioni soggettive protette, vale a dire diritti e interessi legittimi), ma anche l’interesse generale della collettività alla stabilizzazione degli effetti delle decisioni pubbliche. La tematica è resa ancora più attuale dal d.l. n. 76/2020 (cd. «decreto semplificazioni») che nel settore dei contratti pubblici ha introdotto misure protettive dell’amministrazione e degli interessi sottesi al contratto (il riferimento è, in particolare, all’estensione del perimetro di applicazione dell’art. 125 c.p.a.), inevitabilmente limitative dell’effettività della tutela giurisdizionale. Il contributo induce a riflettere sulla persistente, consistente ed ineliminabile presenza dell’interesse pubblico nell’ambito del processo amministrativo e sulla tenace propensione del giudice amministrativo a esercitare ampi margini di valutazione in nome di tale interesse.

description: We calculate, in a systematic way, the general structure of the self-energy of light massive fermions and the effective propagator in a thermomagnetic medium with the inclusion of anomalous magnetic moment (AMM) of the fermion in the weak field approximation. It is found that the self-energy of a massive fermion in this case consists of five non-trivial structure factors in contrast to the massless case where the self-energy contains only four. We employ the real time formalism (RTF) of thermal field theory within the ambit of hard thermal loop (HTL) approximation in the evaluation of the structure factors. The collective modes are obtained from the poles of the effective propagator of the fermion. The investigation of the dispersion relations for non-degenerate ground state shows that the effect of the magnetic field is more for up quark than the down quark because of the larger charge of the former. The important observation is that in the first excited state the degeneracy, which exists for non-zero magnetic field is lifted due to the inclusion of the AMM. It is also observed that the first excited state becomes less dispersive compared to the case when AMM is not considered, whereas the second excited state becomes more dispersive when both the magnetic field and the AMM are non-zero in comparison to the case with vanishing AMM. These effects are observed in both particle and hole-like excitations. Qualitatively similar behaviour is also seen in the case of down quarks.

description: Unmanned aerial vehicles (UAVs) have gained popularity in the communications research community because of their versatility in placement and potential to extend the functions of communication networks. However, there remains still a gap in existing works regarding detailed and measurement-verified air-to-ground (A2G) Massive Multi-Input Multi-Output (MaMIMO) channel characteristics which play an important role in realistic deployment. In this paper, we first design a UAV MaMIMO communication platform for channel acquisition. We then use the testbed to measure uplink Channel State Information (CSI) between a rotary-wing drone and a 64-element MaMIMO base station (BS). For characterization, we focus on multidimensional channel stationarity which is a fundamental metric in communication systems. Afterward, we present measurement results and analyze the channel statistics based on power delay profiles (PDPs) considering space, time, and frequency domains. We propose the stationary angle (SA) as a supplementary metric of stationary distance (SD) in the time domain. We analyze the coherence bandwidth and RMS delay spread for frequency stationarity. Finally, spatial correlations between elements are analyzed to indicate the spatial stationarity of the array. The space-time-frequency channel stationary characterization will benefit the physical layer design of MaMIMO-UAV communications.

description: After the outbreak of the COVID-19 pandemic, several commentators, especially from non-academic fields, speculated about a potential exodus from urban to rural areas. However, this hypothesis has not been confirmed due to a lack of data with information capturing changes of residence at local level. This issue of Perspectives Demogràfiques offers the main results of a study led by the Centre for Demographic Studies and the Autonomous University of Barcelona which analyses internal migration between cities, suburbs, and rural areas in 2020, compared to migration patterns during the four years preceding the pandemic. The analysis used microdata from the Residential Variation Statistics (EVR) of the Spanish Statistical Office (INE) which cover all changes of residence in the country’s 8,131 municipalities. The results show significant changes in internal migration patterns during 2020. Inmigration to cities decreased, while out-migration increased, especially to rural areas. The latter flow had an important demographic impact on country villages. Despite these changes, internal migratory movements between and within urban areas dominated, as they did prior to the pandemic. At the same time, monthly data suggest that the changes are likely a temporary outcome

description: In a recent and celebrated article, Smirnov [Ann. of Math. (2) 172 (2010) 1435-1467] defines an observable for the self-dual random-cluster model with cluster weight q = 2 on the square lattice $\mathbb{Z}^2$, and uses it to obtain conformal invariance in the scaling limit. We study this observable away from the self-dual point. From this, we obtain a new derivation of the fact that the self-dual and critical points coincide, which implies that the critical inverse temperature of the Ising model equals $1/2\log(1+\sqrt{2})$. Moreover, we relate the correlation length of the model to the large deviation behavior of a certain massive random walk (thus confirming an observation by Messikh [The surface tension near criticality of the 2d-Ising model (2006) Preprint]), which allows us to compute it explicitly.

description: L’emergenza da Covid-19 ha posto il dibattito attorno ai poteri d’urgenza al centro dell’attenzione. Il presente contributo è volto a fornire una ricostruzione critica dei poteri emergenziali attivati per fare fronte all’emergenza sanitaria in atto, focalizzandosi – da un lato – sul rapporto tra l’impianto emergenziale creato nel contesto dell’emergenza da Covid-19 e la normativa generale in materia di protezione civile e – dall’altro lato – sul ruolo rivestito dalla Regioni nella gestione dell’emergenza da Covid-19. A tal fine, lo studio parte, innanzitutto, da una ricostruzione dei poteri d’urgenza, in generale, e della normativa in materia di protezione civile, in particolare, al fine di evidenziare le caratteristiche, i presupposti e limiti dei poteri d’urgenza nell’ordinamento italiano. A tale inquadramento generale segue l’analisi del rapporto tra la normativa dell’emergenza Covid-19 e la normativa prevista in materia di protezione civile. In particolare, il contributo pone il quesito circa la necessità e legittimità della scelta di prevedere una disciplina speciale e derogatoria rispetto a quella già prevista in materia di protezione civile per fare fronte all’emergenza da Covid-19. A tal riguardo, il contributo giunge alla conclusione che la decisione di adottare una disciplina speciale per fronteggiare la pandemia sembra condivisibile, oltre che legittima e forse anche necessaria. Dopo questa prima conclusione, lo studio si concentra sul ruolo riconosciuto alle Regioni nell’ambito della gestione dell’emergenza da Covid-19 ponendo, in particolare, il quesito se il riconoscimento di una quota di potere emergenziale alle regioni fosse una soluzione costituzionalmente necessitata. A riguardo si giunge alla conclusione che tale scelta fosse più che altro motivata da ragioni sia giuridiche che politiche.

description: We refine stochastic calculus for symmetric Markov processes without using time reverse operators. Under some conditions on the jump functions of locally square integrable martingale additive functionals, we extend Nakao's divergence-like continuous additive functional of zero energy and the stochastic integral with respect to it under the law for quasi-everywhere starting points, which are refinements of the previous results under the law for almost everywhere starting points. This refinement of stochastic calculus enables us to establish a generalized Fukushima decomposition for a certain class of functions locally in the domain of Dirichlet form and a generalized Itô formula.

description: Longitudinal imaging studies have moved to the forefront of medical research due to their ability to characterize spatio-temporal features of biological structures across the lifespan. Credible models of the correlations in longitudinal imaging require two or more pattern components. Valid inference requires enough flexibility of the correlation model to allow reasonable fidelity to the true pattern. On the other hand, the existence of computable estimates demands a parsimonious parameterization of the correlation structure. For many one-dimensional spatial or temporal arrays, the linear exponent autoregressive (LEAR) correlation structure meets these two opposing goals in one model. The LEAR structure is a flexible two-parameter correlation model that applies in situations in which the within-subject correlation decreases exponentially in time or space. It allows for an attenuation or acceleration of the exponential decay rate imposed by the commonly used continuous-time AR(1) structure. Here we propose the Kronecker product LEAR correlation structure for multivariate repeated measures data in which the correlation between measurements for a given subject is induced by two factors. We also provide a scientifically informed approach to assessing the adequacy of a Kronecker product LEAR model and a general unstructured Kronecker product model. The approach provides useful guidance for high dimension, low sample size data that preclude using standard likelihood based tests. Longitudinal medical imaging data of caudate morphology in schizophrenia illustrates the appeal of the Kronecker product LEAR correlation structure.
Emergenza, pandemia ed intervento dell’autorità sull’impresa bancaria

description: Gli interventi emergenziali, nel diritto bancario, non rappresentano una novità: nel tempo si è lentamente stratificato un complesso di interventi dettati quasi sempre dalla necessità di sopperire a circostanze puntuali e contingenti. L’uso/abuso del diritto emergenziale spesso si accompagna a deroghe rispetto alle regole ordinarie e porta ad una progressiva deformazione dello Stato di diritto. Per dare una lettura coerente del sistema diventa necessario adottare la prospettiva della tutela del risparmio, inteso come unico centro di interessi di rilievo pubblico che vede il punto di unificazione nella prospettiva dei diritti delle persone: solo così si riesce a superare il contrasto tra contrapposizione di interessi. Nella prospettiva dei diritti, le Autorità di vigilanza possono porre vincoli alla libertà d’impresa delle banche, nella loro autonomia organizzativa e nella operatività gestionale (quindi anche nella fissazione di requisiti patrimoniali o nell’imposizione di vincoli alla distribuzione degli utili). Possiamo, dunque, ritenere che, nella fase emergenziale, gli interventi del regolatore rappresentano il frutto di un processo evolutivo che diventa espressione del requisito di organizzazione funzionale al perseguimento del principio di sana e prudente gestione.

The role of enterprise systems standardization on data breach occurrence
Creators: name: Chu, Scott
Publisher: name: University of British Columbia
Year: 2023

description: This study examines the relationship between enterprise systems standardization and data breach occurrence. We argue that the greater degree of compatibility resulting from sourcing enterprise systems modules from fewer vendors (i.e., higher enterprise systems standardization) enables easier management of the implemented modules and creates less cybersecurity risks. To test our hypothesis, we use a panel dataset from 2007 to 2017 constructed from the Aberdeen Computer Intelligence Technology Database, Advisen Cyber Loss Database, and Compustat. We find enterprise systems standardization to be negatively related to data breach occurrence. However, when we drill down to different data breach types, we only find enterprise systems standardization to be negatively related to data breaches that are caused by perpetrators external to the firm or data breaches that involve the compromise of individuals’ data. To address endogeneity concerns, we implement an instrumental variable approach which allows us to be more confident that our results better represent a causal relationship. While there is no conclusive evidence that indicates whether sourcing enterprise systems modules from fewer vendors is generally advantageous or disadvantageous, to the best of our knowledge, our findings suggest that sourcing modules from fewer vendors is, at least, advantageous from a cybersecurity standpoint.

description: The theory of macroscopic gravity provides a formalism to average the Einstein field equations from small scales to largest scales in space-time. It is well known that averaging is an operation that does not commute with calculating the Einstein tensor and this leads to a correction term in the field equations known as back-reaction. In this work, we derive exact solutions to the macroscopic gravity field equations assuming that the averaged geometry is plane or spherically symmetric, and the source is taken as vacuum, dust, or perfect fluid. We then focus on the specific cases of spherical symmetry and derive solutions that are analogous to the Schwarzschild, Tolman VII, and Lema\^ıtre-Tolman-Bondi solutions. The geodesic equations and curvature structure are contrasted with the general relativistic counterparts for the Schwarzschild and Lema\^ıtre-Tolman-Bondi solutions.

As a result we demonstrate a 10 GHz frequency comb with over 100 lines in a 10-dB bandwidth in which a record 75 lines are within a flatness of 1-dB. The cascaded four-wave mixing process increases the bandwidth of the initial comb generated by modulation of a CW laser by a factor of five. The broadband comb has approximately quadratic spectral phase, which is compensated upon propagation in single mode fiber, resulting in a 10 GHz train of 940 fs pulses

description: We develop a high-dimensional neural network potential (NNP) to describe the structural and energetic properties of borophene deposited on silver. This NNP has the accuracy of DFT calculations while achieving computational speedups of several orders of magnitude, allowing the study of extensive structures that may reveal intriguing moiré patterns or surface corrugations. We describe an efficient approach to constructing the training data set using an iterative technique known as the "adaptive learning approach". The developed NNP potential is able to produce, with an excellent agreement, the structure, energy and forces of DFT. Finally, the calculated stability of various borophene polymorphs, including those not initially included in the training dataset, shows better stabilization for $ν\sim0.1$ hole density, and in particular for the allotrope $α$ ($ν=\frac{1}{9}$). The stability of borophene on the metal surface is shown to depend on its orientation, implying structural corrugation patterns that can only be observed from long time simulations on extended systems. The NNP also demonstrates its ability to simulate vibrational densities of states and produce realistic structures, with simulated STM images closely matching the experimental ones.
Precauzione, prevenzione e legalità nell’emergenza da Covid-19

description: Nella gestione dell’epidemia da Covid 19, il nostro Paese ha fatto massiccio ricorso a misure emergenziali, ossia atipiche e sottratte al principio di legalità sostanziale, ma frequentemente fondate sul rischio sanitario. Si tratta di misure precauzionali atipiche? Ordinariamente le misure precauzionali sono tipiche, mentre le misure preventive, fondate sul pericolo, sono misure atipiche – laddove, in senso giuridico, il rischio è un evento dannoso futuro, ma incerto per via dell’assenza di conoscenze scientifiche, mentre il pericolo è un evento futuro, relativamente imminente e sufficientemente probabile, alla luce dell’esperienza e delle conoscenze tecnico-scientifiche. Le misure precauzionali non possono essere atipiche, perché derogano alla ragionevolezza/proporzionalità della decisione: delle premesse di quella decisione non si può determinare la verità e non si è in grado di formulare previsioni sufficientemente affidabili per valutare l’impatto delle misure sugli interessi (e di conseguenza non si può valutare il bilanciamento tra questi e l’idoneità e la necessità delle misure adottate). L’epidemia da Covid-19 è tuttavia un pericolo, in senso giuridico, non un rischio: conosciamo a sufficienza le modalità di trasmissione del virus e le misure idonee a fermarne l’avanzata. Sicché le misure di gestione della pandemia sono misure di prevenzione, non precauzionali, ma non solo per questo sicuramente legittime. Le misure di prevenzione possono essere adottate rispetto ad un evento imprevedibile. Almeno la seconda ondata era prevedibile. Sicché essa doveva essere gestita sulla base di misure ordinarie, soggette al principio di legalità.

On the effect of physiological acidosis in hibernating rodents
Creators: name: Kim, Anne
Publisher: name: University of British Columbia
Year: 2023

description: Metabolic rate suppression during hibernation requires an orchestrated global reduction in metabolism while still matching O₂ supply and demand. Acidosis has been suggested as a mechanism for suppressing metabolic rate in hibernation, although the mechanism behind this process has not been thoroughly investigated. Findings from my thesis indicate that hemoglobin of both the facultative hibernator (Syrian hamster) and the obligate hibernator (13-lined ground squirrel) exhibit a reduced temperature sensitivity and increased Bohr effect relative to the non-hibernating rat, ultimately enhancing O₂ offloading at the tissues. I also found that in the obligate hibernator, due to metabolic state-dependent changes in intracellular buffering constituents, the ionisation ratio of intracellular imidazole (αim) did not vary between euthermia and hibernation. In the facultative hibernator, αim remained constant regardless of hibernation state. These findings contradict previous speculation that acidosis may suppress metabolism in quiescent tissues such as the brain and skeletal muscle during hibernation. Furthermore, mitochondrial respiration increased at low pH despite the reduced activity of electron transport system (ETS) enzymes at low pH. This suggests that, despite ETS enzyme activity being reduced at low pH, acidosis may reverse the inhibitory mechanisms that suppress mitochondrial respiration during steady-state hibernation, leading to the observed increase in mitochondrial respiration at low pH. Lastly, acidosis decreased cellular ATPase activity in the hibernating species but not in the rat. In the obligate hibernator, this inhibitory effect of acidosis on cellular ATPase activity was present regardless of hibernation state and assay temperature (37 – 10 °C). In the facultative hibernator, the effect of acidosis on ATPase activity was only present during euthermia and at warm temperatures. Taken together, these findings indicate that acidosis does not occur in quiescent tissues of hibernators or lower mitochondrial O₂ consumption. Instead, it may serve a role in matching O₂ supply to the high O₂ demand during arousal by increasing O₂ offloading by hemoglobin. Collectively, these data provide novel insight into the role of acidosis during hibernation that were previously uncharacterised.
Sullo statuto costituzionale dell’emergenza. Ancora sul diritto pubblico come violenza o come funzione dei diritti della persona

description: L’emergenza pandemica ha reso più visibili processi già largamente in atto e destinati a non venire meno quando la pandemia sia superata. Poteri derogatori, organizzazioni ad hoc, anticipazione dell’emergenza al ricorrere di rischi ordinari e non di stretta necessità, estendersi di spazi di valutazione discrezionale sono tendenze largamente in atto da tempo. Da questo punto di vista, il dibattito sul regime costituzionale dell’emergenza finisce per approdare, da percorsi diversi, alla conclusione che essa si legittimi per via della salvezza dello Stato e dell’ordinamento. A fronte delle tendenze in atto e dei problemi che si manifestano, sembra invece necessario radicare il problema dell’emergenza – in linea con la tradizione del diritto europeo – nella sovranità e, poiché essa appartiene al popolo e la stessa autorità è resa interamente funzionale ai diritti inviolabili, il regime costituzionale dell’emergenza deve essere inteso come funzionale alla salvezza dei diritti fondamentali di fronte a pericoli imminenti e non alla salvezza dello Stato o in generale dell’autorità e del suo potere di comando. Emergency has become, in the past years, all ordinary. Covid-19 emergency revealed more clearly the large use of emergency in the legal system. The large use of emergency in the past years provide a wide range of legal means, mainly in via of exception and derogation. More specifically, Covid-19 emergency implement the various techniques, adding new measures, mainly to anticipate emergency measures based on risks instead of an actual or imminent risk, to appreciate emergency’s conditions in a discretionary fashion and with legal provision vague and unsubstantiated into the legislative decrees adopted to cope with the pandemic. In this critical situation, of derogations from normal human rights standards and alterations in the distribution of functions and powers among the different organs of the State, a discussion on constitutional status of emergency is mandatory. Italian academic writing during Covid-19 emergency seems unsatisfactory: Literature argued mainly in two – opposite – directions: under a positivistic perspective, Italian Constitution in force grounds emergency, as a way to conserve safety of the State and fundamental principles of the Republic; on the other hand, many scholars recurred to the traditional idea of ex facto oritur ius – therefore, facing extreme danger, facts grounds the State with powers either not by Law or under Constitution. The paper, maintain a positivistic approach and, under express constitutional rules on sovereignty – belonging to persons and recognizing fundamental rights as a component of people’s sovereignty – affirm Constitution grounds emergency powers as much as driven to human rights protection.

description: Il sistema della performance della pubblica amministrazione tra disegno organizzativo e svolgimento della funzione. Lo studio della performance delle pubbliche amministrazioni da parte del giurista deve necessariamente assumere carattere interdisciplinare perché il tema è oggetto privilegiato di studio delle discipline aziendalistiche e del management pubblico. Muovendo da questo approccio, il saggio definisce il concetto di performance ed esamina i due modelli elaborati dalle suddette discipline. Il primo modello è maggiormente orientato a considerare la performance come uno strumento che serve a misurare il rapporto tra le risorse immesse nel processo e ciò che ne scaturisce in termini di output. Il secondo modello è maggiormente orientato a considerare la performance come uno strumento utile non soltanto a misurare il suddetto profilo, ma anche a valutare se l’otuput prodotto sia stato in grado di produrre ulteriori risultati (l’outcome) nel contesto di riferimento in cui si colloca. Esaurita l’analisi interdisciplinare, il saggio esamina quale dei due modelli sia maggiormente conforme al ruolo che la Costituzione assegna alle pubbliche amministrazioni e successivamente illustra i profili problematici della normativa (individuati in particolare nella sostanziale irresponsabilità degli organi titolari dell’indirizzo politico-amministrativo per la violazione degli obblighi gravanti sugli stessi in relazione al piano delle performance). Nella parte conclusiva il saggio individua gli effetti che il sistema di valutazione della performance determina sull’organizzazione e l’azione delle pubbliche amministrazioni.

The distribution, kinematics and luminosities of extreme helium stars as probes of their origin and evolution

description: Hydrogen deficient stars include the cool R CrB variable (RCBs) and hydrogen-deficient carbon (HdCs) giants through extreme helium stars (EHes) to the very hot helium-rich subdwarfs (He-sdO and O(He) stars) and white dwarfs. With surfaces rich in helium, nitrogen and carbon, their origins have been identified with the merger of two white dwarfs. Using Gaia to focus on the EHes, we aim to identify progenitor populations and test the evolution models. Gaia DR3 measurements and ground-based radial velocities have been used to compute Galactic orbits using galpy. Each orbit has been classified by population; EHe stars are found in all of the thin disk, thick disk, halo and bulge, as are RCB, HdC and He-sdO stars. Spectral energy distributions were constructed for all EHes, to provide angular diameters, and hence radii and luminosities. The EHes fall into two luminosity groups divided at L ~ 2500 solar L. This supports theory for the origin of EHes, and is the strongest confirmation so far in terms of luminosity. The lower luminosity EHes correspond well with the post-merger evolution of a double helium white dwarf binary. Likewise, the higher luminosity EHes match the post-merger evolution of a carbon/oxygen plus helium white dwarf binary. In terms of parent populations, current models predict that double white dwarf mergers should occur in all Galactic populations, but favour mergers arising from recent star formation (i.e. thin disk), whereas the statistics favour an older epoch (i.e. thick disk).

description: Among the many interesting features displayed by graphene, one of the most attractive is the simplicity with which its electronic structure can be described. The study of its physical properties is significantly simplified by the linear dispersion relation of electrons in a narrow range around the Fermi level. Unfortunately, the mathematical simplicity of graphene electrons is only limited to this narrow energy region and is useless when dealing with problems that involve energies outside the linear dispersion part of the spectrum. In this letter we remedy this limitation by deriving a set of closed-form analytical expressions for the real-space single-electron Green function of graphene which are valid across an enormous fraction of the energy spectrum. By extending to a wider energy range the simplicity with which graphene electrons are described, it is now possible to derive more mathematically transparent and insightful expressions for a number of physical properties that involve higher energy scales. The power of this new formalism is illustrated in the case of the magnetic (RKKY) interaction in graphene.
