Multi-hazard perspectives on risk perception, disaster preparedness, and emergency management
Creators: name: Tanner, Alexa
Publisher: name: University of British Columbia
Year: 2022

description: To adequately address the changing risks of natural hazards, traditional single-hazard frameworks and approaches must be refined to recognize the multi-hazard realities in which individuals and communities manage risks. This involves refining how academics and practitioners operationalize risk perceptions in the face of multi-hazard risks and adapting how community resilience is fostered. Drawing on the natural hazards, risk perceptions, and risk management fields of study, this dissertation investigates and demonstrates the importance of multi-hazard risks in the social science study of disasters. It uses three studies to examine how individuals and communities prepare and respond to multiple natural hazards, and is guided by the research question: How can a multiple natural hazard perspective contribute to understanding community resilience to disasters? Study 1 looks at multi-hazard risk perceptions at the individual level. Through a household survey (n=1,064) conducted in Kyushu, Japan, it finds evidence of cross-over effects whereby personal experience with one hazard influences risk perceptions of other hazards. Study 2 focuses on emergency managers’ experiences with preparedness and response in the face of multiple hazards, including natural hazards and the COVID-19 pandemic. Through interviews with 29 emergency managers serving a diversity of communities across British Columbia, it finds that these professionals’ perceptions and actions are influenced and constrained by funding and other institutional structures that were designed with a focus on single hazards. Study 3 examines how Canadian society prepares for emergencies and how individual preparedness differs between community types. Using a large survey dataset from Statistics Canada’s Survey of Emergency Preparedness and Resilience, it finds notable differences in multi-hazard risk perception, disaster experience, and emergency preparedness between populations in major urban centres and small communities. Together, these three studies conceptualize and provide insight into how communities and individuals perceive, prepare for, and respond to multiple natural hazards and provides recommendations on how adaptation can be supported to address changing multi-hazard risk profiles.

description: The existence and origin of line tension has remained controversial in literature. To address this issue we compute the shape of Lennard-Jones nanodrops using molecular dynamics and compare them to density functional theory in the approximation of the sharp kink interface. We show that the deviation from Young's law is very small and would correspond to a typical line tension length scale (defined as line tension divided by surface tension) similar to the molecular size and decreasing with Young's angle. We propose an alternative interpretation based on the geometry of the interface at the molecular scale.
Per quiete della città: l’istituzione della truppa civica di Firenze l’11 aprile 1780

description: Attraverso la comparazione di due provvedimenti, quelli istitutivi della truppa civica senese (1778) e fiorentina (1780) – quest’ultimo qui integralmente trascritto – il riformismo leopoldino appare dipanarsi secondo direttrici e obiettivi non omogenei: a Siena con il pieno coinvolgimento del ceto dirigente locale e con l’esautorazione di colui, Francesco Maria Gianni, che a stretto contatto con il granduca aveva ideato la riforma; a Firenze tornando a riconoscere al Gianni il ruolo di indiscusso capofila dei lavori preparatori della legge. Le truppe civiche vengono istituite in diversi luoghi del Granducato: se vi sono indubbi punti di contatto con il sistema delle bande territoriali, l’impianto delle nuove milizie (mai peraltro approfonditamente indagato) ha alla base un’idea nuova di comunità e di suddito, responsabilizzati nell’ambito della sorveglianza sulla vita della città e sulle occasioni di sociabilità urbana in particolare. Su di esse si aprono squarci preziosi, che danno la misura sia delle contraddizioni che una truppa con mansioni sull’ordine pubblico e costituita da ‘nazionali’ poteva produrre, sia delle forti tensioni che agitavano la società toscana.

Consiglieri e consigli del Comune di Firenze nel Duecento. A proposito di alcune liste inedite

Year: 2011

description: Per l’eccezionale rilevanza attribuita dalla storiografia alle vicende della Firenze medievale, è piuttosto diffusa la convinzione che anche la storia duecentesca della città sia facilmente indagabile grazie a una presumibile ricchezza di fonti documentarie. In realtà, la disponibilità di documentazione pubblica fiorentina fino agli anni Ottanta di quel secolo è modesta, e per tale motivo si offre qui l’edizione di alcuni atti contenenti ciascuno liste di consiglieri fioren- tini finora inedite. Tali elenchi sono preziosi sia per i dati che registrano, sia perché forniscono uno spunto di riflessione sull’autorità pubblica attribuita nel corso del XIII secolo alle istituzioni comunali. L’analisi formale dei documenti consente infatti di registrare, intorno agli anni Ottanta, un netto cambiamento nelle pratiche cancelleresche del Comune, sintomo, questo, dell’affermarsi di una nuova valutazione del ruolo delle istituzioni: l’ascesa al potere del Secondo Popolo segnò di fatto il passaggio da una fase in cui la responsabilità delle decisioni di governo ricadeva sui singoli che, di volta in volta, ricoprivano le cariche, a un’altra in cui si affermò, finalmente, il pieno riconoscimento dell’autorità pubblica degli organismi istituzionali comunali.

description: Il saggio ricostruisce la cerimonia del 27 ottobre 1934 per la traslazione nella chiesa di Santa Croce a Firenze dei corpi di trentasette «martiri» fascisti fiorentini, tutti squadristi morti negli scontri del primo dopoguerra. La cerimonia, inse- rita nel culto dello squadrismo che il regime accentua all’inizio degli anni Trenta, vede la Firenze fascista mobilitata in tutte le sue organizzazioni per la perfetta riuscita del rito, al quale partecipa anche Mussolini. Il saggio ricostruisce la giornata del 27 ottobre 1934 attraverso documentazione d’archivio e i commenti della stampa coeva, tutti tesi ad esaltare quel senso vitale e costruttivo per il cammino della ‘rivoluzione’ verso nuove mete che, secondo la liturgia fascista dei caduti, emanava dal ‘sacrificio’ dei primi squadristi.

description: Evaporation of water droplets on a superhydrophobic substrate, on which the contact line is pinned, is investigated. While previous studies mainly focused on droplets with contact angles smaller than 90^\circ, here we analyze almost the full range of possible contact angles (10^\circ -150^\circ). The greater contact angles and pinned contact lines can be achieved by the use of superhydrophobic Carbon Nanofiber substrates. The time-evolutions of the contact angle and the droplet mass are examined. The experimental data is in good quantitative agreement with the model presented by Popov (Physical Review E 71, 2005), demonstrating that the evaporation process is quasi-static, diffusion-driven, and that thermal effects play no role. Furthermore, we show that the experimental data for the evolution of both the contact angle and the droplet mass can be collapsed onto one respective universal curve for all droplet sizes and initial contact angles.
Accademie teatrali fiorentine nel quartiere di Santa Croce tra Sei e Settecento: tra attori dilettanti, gioco d’azzardo e primi tentativi impresariali

description: Il saggio approfondisce il funzionamento delle accademie teatrali fiorentine a cavallo tra XvII e XvIII secolo sotto più punti di vista: localizzazione dei teatri, repertorio e circolazione degli interpreti, aspetti di amministrazione economica, rapporti con il potere e, nella fattispecie, con la dinastia medicea. Emerge la concentrazione nel quartiere di Santa Croce di Firenze di una buona parte delle accademie di dilettanti, che per alcuni decenni offrono una produzione drammaturgica alternativa a quella del teatro degli attori professionisti, esclusi dal mercato fiorentino nell’ultima fase medicea. Sulle motivazioni di questo fenomeno sono qui proposte ipotesi alternative alla vulgata storiografica che vede in questi anni il nadir culturale nella storia del Granducato e della famiglia al potere. Ci si sofferma, inoltre, sul problema di una possibile definizione di sistema teatrale fiorentino, con particolare attenzione alla disanima dei primi tentativi di adozione di un modello impresariale nel teatro in musica.

Year: 2011

description: In questo saggio si affronta la storia dell’educazione alla corte dei Medici tra Cinque e Seicento, privilegiando il rapporto fra le granduchesse e i loro figli. Le fonti utilizzate per una prima indagine sul tema sono alcuni ruoli della corte dall’epoca di Cosimo I a quella di Cosimo III, i carteggi del fondo Mediceo del Principato e alcune fonti letterarie attinenti ai programmi pedagogici concepiti per i giovani principi di casa Medici. La scelta del lungo periodo è motivata dall’intento di cogliere i passaggi cruciali che connotano nel tempo l’evoluzione in senso nobiliare-cavalleresco dell’educazione dei primogeniti e dei cadetti maschi, mentre per le principesse destinate al matrimonio o al convento si delinea la persistenza dei modelli educativi legati alle virtù domestiche e morali in genere, calibrate di volta in volta sulle inclinazioni personali. Il denominatore comune di una regia pedagogica articolata fu quello che corrispose al graduale passaggio dalla casa, alla corte, al mondo, dove l’immagine e la reputazione di principi e principesse doveva proiettarsi per l’onore della famiglia, dello Stato e del rango.

Creators: name: Niemeier, Johannes

Publisher: name: Royal Society of Chemistry
Year: 2023

description: The catalytic conversion of biomass and biogenic platform chemicals typically requires the use of solvents. Water is present already in the raw materials and in most cases a suitable solvent for the typically highly polar substrates. Hence, the development of novel catalytic routes for further processing would profit from the optimization of the reaction conditions in the aqueous phase mainly for energetic reasons by avoiding the initial water separation. Herein, we report the amination of biogenic alcohols in aqueous solutions using solid Ru-based catalysts and ammonia as a reactant. The influence of different support materials and bimetallic catalysts is investigated for the amination of isomannide as a biogenic diol. Most importantly, the transferability of the reaction conditions to various other primary and secondary alcohols is successfully proved. Hence, water appears to be a suitable solvent for the sustainable production of biogenic amines and offers great potential for further process development.

description: The microscopic dynamics and aging of a soft thermosensitive suspension was investigated by looking at the thermal fluctuations of tracers in the suspension. Below and above the glass transition, the dense microgel particles suspension was found to develop an heterogeneous dynamics, featured by a non Gaussian Probability Distribution Function (PDF) of the probes' displacements, with an exponential tail. We show that non Gaussian shapes are a characteristic of the ensemble-averaged PDF, while local PDF remain Gaussian. This shows that the scenario behind the non Gaussian van Hove functions is a spatially heterogeneous dynamics, characterized by a spatial distribution of locally homogeneous dynamical environments through the sample, on the considered time scales. We characterize these statistical distributions of dynamical environments, in the liquid, supercooled, and glass states, and show that it can explain the observed exponential tail of the van Hove functions observed in the concentrated states. The intensity of spatial heterogeneities was found to amplify with increasing volume fraction. In the aging regime, it tends to increase as the glass gets more arrested.

Mechanistic insights into the inhibition of stress granule formation by a viral protein
Creators: name: Sadasivan, Jibin
Publisher: name: University of British Columbia
Year: 2022

description: Stress granules (SG) are ribonucleoprotein aggregates that accumulate during cellular stress when translation is limited. Inhibition of SG assembly has been observed under virus infection across species, suggesting a conserved fundamental viral strategy. However, the significance of SG modulation during virus infection is not fully understood. The 1A protein encoded by the model dicistrovirus, Cricket Paralysis Virus (CrPV), is a multifunctional viral protein that can inhibit SG formation and bind to and degrade Argonaute-2 (Ago-2) in an E3 ubiquitin ligase-dependent manner to block the antiviral RNA interference pathway. Moreover, the R146 residue at the C-terminus of 1A is necessary for virus infection in Drosophila S2 cells and flies. Here, I uncouple CrPV-1A's functions and provide insights into its underlying mechanism for SG inhibition. CrPV-1A’s ability to inhibit SG formation does not require the Ago-2 binding domain but does require the E3 ubiquitin ligase binding domain. Overexpression and infection studies in Drosophila and human cells showed that wild-type CrPV-1A but not mutant R146A CrPV-1A localizes to the nuclear membrane, which correlates with nuclear enrichment of poly(A)+ RNA. Transcriptome analysis demonstrated that a single R146A mutation dramatically dampens host transcriptome changes in CrPV-infected cells. Finally, inhibition of SG formation by CrPV-1A requires Ranbp2/Nup358 in an R146-dependent manner. I propose that CrPV utilizes a multifaceted strategy for productive virus infection whereby the CrPV-1A protein interferes with a nuclear event that contributes to the suppression of SG assembly.

We show that the Poisson distribution gets modified, and that the vacuum state evolves into a "squeezed" state rather than a coherent state. The time evolutions of uncertainties in position and momentum in vacuum are also studied and imply interesting consequences for modeling nonlinear phenomena in quantum optics.

Il padre a Firenze nel Quattrocento. L’educazione del pupillo in Giovanni Morelli

Year: 2011

description: Il saggio contiene una lettura analitica dei «sette danni al pupillo», una sorta di sezione programmatica del testo dei Ricordi scritti da Giovanni Morelli nel Xv secolo. I consigli che il Morelli rivolge ai figli rivelano nel suo pensiero un aspetto tecnico-razionale che si traspone sul mondo degli affetti, della famiglia e della società. Il Morelli impartisce consigli pragmatici, basati su un continuo rifarsi all’esperienza, che presuppongono una società sostanzialmente statica, fon- data su meccanismi capaci di ripetersi nel tempo. Questa continuità lo induce a pensare di poter trasmettere ai figli il suo sapere pratico-sociale e il contenuto tecnico della sua personale esperienza, perché possano penetrare i meccanismi del reale e sfruttarli a proprio vantaggio senza rimanerne vittime. Ne risulta un tentativo, quasi scientifico, di sistematizzare e modellare la realtà a venire sulla base del vissuto.

description: Extreme mass ratio inspirals, in which a stellar-mass object merges with a supermassive black hole, are prime sources for space-based gravitational wave detectors because they will facilitate tests of strong gravity and probe the spacetime around rotating compact objects. In the last few years of such inspirals, the total phase is in the millions of radians and details of the waveforms are sensitive to small perturbations. We show that one potentially detectable perturbation is the presence of a second supermassive black hole within a few tenths of a parsec. The acceleration produced by the perturber on the extreme mass-ratio system produces a steady drift that causes the waveform to deviate systematically from that of an isolated system. If the perturber is a few tenths of a parsec from the extreme-mass ratio system (plausible in as many as a few percent of cases) higher derivatives of motion might also be detectable. In that case, the mass and distance of the perturber can be derived independently, which would allow a new probe of merger dynamics.

description: Il saggio affronta il primo periodo della storia delle Stinche, la prigione del Comune di Firenze istituita intorno al 1300, riservando particolare attenzione al rapporto tra carcerati e tra questi e il mondo esterno. Rispetto ad altri casi, la vita nella prigione fiorentina è ben documentata, ciò che ne consente un’analisi approfondita. I documenti dimostrano che un regime carcerario semi-inclusivo, tipico di questo periodo, riusciva a impedire il completo isolamento sociale dei prigionieri, attenuando loro le sofferenze del carcere. In tale prospettiva, il caso analizzato mostra nell’istituzione della prigione un cambiamento nell’atteggiamento verso la marginalità sociale e religiosa: dall’espulsione al suo contenimento.

description: We investigate the low temperature thermodynamics and correlation functions of one-dimensional spin-1/2 fermions with strong repulsion in an external magnetic field via the thermodynamic Bethe ansatz method. The exact thermodynamics of the model in a weak magnetic field is derived with the help of Wiener-Hopf techniques. It turns out that the low energy physics can be described by spin-charge separated conformal field theories of an effective Tomonaga-Luttinger liquid and an antiferromagnetic SU(2) Heisenberg spin chain. However, these two types of conformally invariant low-lying excitations may break down as excitations take place far away from the Fermi points. The long distance asymptotics of the correlation functions and the critical exponents for the model in the presence of a magnetic field at zero temperature are derived in detail by solving dressed charge equations and by conformal mapping. Furthermore, we calculate the conformal dimensions for particular cases of correlation functions. The leading terms of these correlation functions are given explicitly for a weak magnetic field $H\ll 1$ and for a magnetic field close to the critical field $H\rightarrow H_{c}$. Our analytical results provide insights into universal thermodynamics and criticality in one-dimensional many-body physics.

All-optical diode action in asymmetric nonlinear photonic multilayers with perfect transmission resonances

Publisher: name: arXiv
Year: 2010
Subjects: subject: Optics (physics.optics)

description: Light propagation in asymmetric Kerr-nonlinear multilayers with perfect transmission resonances is theoretically investigated. It is found that hybrid Fabry-Pérot/photonic-crystal structures of the type (BA)^k(AB)^k(AABB)^m exhibit both pronounced unidirectionality (due to strong spatial asymmetry of the resonant mode) and high transmission (due to the existence of a perfect transmission resonance). This results in nonlinear optical diode action with low reflection losses without need for a pumping beam or input pulse modulation. By slightly perturbing the perfect transmission resonance condition, the operating regime of the optical diode can be tuned, with a trade-off between minimizing the reflection losses and maximizing the frequency bandwidth where unidirectional transmission exists. Optical diode action is demonstrated in direct numerical simulation, showing >92% transmittance in one direction and about 22% in the other. The effect of perfect transmission resonance restoration induced by nonlinearity was observed analytically and numerically. The proposed geometry is shown to have advantages over previously reported designs based on photonic quasicrystals.

description: Three-dimensional Voronoi analysis is used to quantify the clustering of inertial particles in homogeneous isotropic turbulence using data from numerics and experiments. We study the clustering behavior at different density ratios and particle response times (i.e. Stokes numbers St). The Probability Density Functions (PDFs) of the Voronoi cell volumes of light and heavy particles show a different behavior from that of randomly distributed particles -i.e. fluid tracers-implying that clustering is present. The standard deviation of the PDF normalized by that of randomly distributed particles is used to quantify the clustering. Light particles show maximum clustering for St around 1-2. The results are consistent with previous investigations employing other approaches to quantify the clustering. We also present the joint PDFs of enstrophy and Voronoi volumes and their Lagrangian autocorrelations. The small Voronoi volumes of light particles correspond to regions of higher enstrophy than those of heavy particles, indicating that light particles cluster in higher vorticity regions. The Lagrangian temporal autocorrelation function of Voronoi volumes shows that the clustering of light particles lasts much longer than that of heavy or neutrally buoyant particles. Due to inertial effects, the Lagrangian autocorrelation time-scale of clustered light particles is even longer than that of the enstrophy of the flow itself.

description: Abstract:
The purpose of the study was to compare traditional functional analysis procedures (isolated contingencies) to functional analysis procedures which are modified to include nuanced environmental variables (synthesized contingencies) for children in an outpatient setting in order to determine sensitivity to the isolated or synthesized contingencies. A multi-element design embedded into a multi-treatment design was used to evaluate differentiated rates of challenging behavior across the two analyses for three children exhibiting challenging behaviors. The results supported the utility of the traditional functional analysis (FA) procedures when compared to that of the interview informed synthesized contingency analysis (IISCA) for one of three participants.

Postriboli in Firenze: un’inchiesta del prefetto del 30 novembre 1849
Creators: name: Turno, Michela
Publisher: name: Annali di Storia di Firenze
Year: 2011

description: Nel 1849 le truppe austriache penetrarono nel Granducato toscano permettendo il rientro di Leopoldo II e segnando l’inizio di una nuova restaurazione. Il ritorno all’ordine pre-rivoluzionario non fu però agevolato dalla presenza della milizia straniera che, lungi dall’essere provvisoria, sollevò problemi di natura non solo economica e politico-organizzativa ma anche sanitaria. In particolare, la recrudescenza del morbo sifilitico tra le file dei militari, diretta conseguenza della crescita nella domanda e nell’offerta del sesso mercenario, costrinse il governo granducale a studiare provvedimenti sanitari contro le ‘femmine infet- tatrici’. L’incarico, affidato al prefetto di Firenze e portato a compimento nel 1855, implicò la raccolta di precedenti disposizioni, progetti di regolamento, suggerimenti e rapporti sulla prostituzione rintracciabili in due nuclei di carte conservati nel fondo della Prefettura del compartimento fiorentino. I documenti qui presentati, vale a dire le relazioni dei delegati di Governo dei quartieri di Santa Maria Novella e di Santo Spirito redatte nel novembre 1849, offrono uno spaccato inedito, intenso e vivace non solo del meretricio fiorentino ma anche delle tensioni e delle fratture sottese all’universo femminile ottocentesco.

description: Mechanisms of the formation and stability of sunspots are among the longest-standing and intriguing puzzles of solar physics and astrophysics. Sunspots are controlled by subsurface dynamics hidden from direct observations. Recently, substantial progress in our understanding of the physics of the turbulent magnetized plasma in strong-field regions has been made by using numerical simulations and local helioseismology. Both the simulations and helioseismic measurements are extremely challenging, but it becomes clear that the key to understanding the enigma of sunspots is a synergy between models and observations. Recent observations and radiative MHD numerical models have provided a convincing explanation to the Evershed flows in sunspot penumbrae. Also, they lead to the understanding of sunspots as self-organized magnetic structures in the turbulent plasma of the upper convection zone, which are maintained by a large-scale dynamics. Local helioseismic diagnostics of sunspots still have many uncertainties, some of which are discussed in this review. However, there have been significant achievements in resolving these uncertainties, verifying the basic results by new high-resolution observations, testing the helioseismic techniques by numerical simulations, and comparing results obtained by different methods. For instance, a recent analysis of helioseismology data from the Hinode space mission has successfully resolved several uncertainties and concerns (such as the inclined-field and phase-speed filtering effects) that might affect the inferences of the subsurface wave-speed structure of sunspots and the flow pattern. It becomes clear that for the understanding of the phenomenon of sunspots it is important to further improve the helioseismology methods and investigate the whole life cycle of active regions, from magnetic-flux emergence to dissipation.

description: In a previous study, we formulated a framework of the entropy-based equilibrium statistical mechanics for self-gravitating systems. This theory is based on the Boltzmann-Gibbs entropy and includes the generalized virial equations as additional constraints. With the truncated distribution function to the lowest order, we derived a set of second-order equations for the equilibrium states of the system. In this work, the numerical solutions of these equations are investigated. It is found that there are three types of solutions for these equations. Both the isothermal and divergent solutions are thermally unstable and have unconfined density profiles with infinite mass, energy and spatial extent. The convergent solutions, however, seem to be reasonable. Although the results cannot match the simulation data well, because of the truncations of the distribution function and its moment equations, these lowest-order convergent solutions show that the density profiles of the system are confined, the velocity dispersions are variable functions of the radius, and the velocity distributions are also anisotropic in different directions. The convergent solutions also indicate that the statistical equilibrium of self-gravitating systems is by no means the thermodynamic equilibrium. These solutions are just the lowest-order approximation, but they have already manifested the qualitative success of our theory. We expect that higher-order solutions of our statistical-mechanical theory will give much better agreement with the simulation results concerning dark matter haloes.

Gli Ordinamenti sulla gabella del sale dell’aprile 1318: un esempio della produzione legislativa fiorentina
Creators: name: Gualtieri, Piero
Publisher: name: Annali di Storia di Firenze
Year: 2011

description: La documentazione normativa rappresenta una delle principali risorse per lo studio del Comune italiano del medioevo. Nella realtà fiorentina essa si articola principalmente fra statuti, ordinamenti e provvisioni. Gli ordinamenti, in particolare, traggono la propria specificità, più che dalla presenza di peculiari elementi formali, dal particolare valore politico ad essi attribuito dalla signoria. È questo il caso di alcuni ordinamenti relativi all’introduzione di una nuova gabella del sale approvati nell’aprile del 1318. L’introduzione di questa nuova imposta, le cui procedure richiamano per certi aspetti fortemente quelle del vecchio estimo, punta a razionalizzare la gestione delle finanze cittadine, in un periodo - segnato dalla concessione della signoria cittadina a re Roberto di Napoli - di aperte ostilità con le forze ghibelline toscane e di deciso fermento all’interno della classe dirigente cittadina.

The role of microsites and life stage in determining translocation success of a globally vulnerable plant variety, Oxytropis campestris var.davisii

description: Translocation is increasingly used as a measure to support the continued existence of rare and endangered plant species. However, historically translocations have a low rate of success, due in part to the lack of knowledge of species-specific habitat requirements. My research focused on the role of microsite features in determining the presence and translocation success of a globally vulnerable perennial plant variety, Oxytropis campestris var. davisii (Fabaceae). This variety is known only from British Columbia (BC) and Alberta (AB), Canada, with BC supporting most of the populations. My research tested the suitability of various microsite habitat types through experimental trials to acquire insight to inform a larger-scale translocation for this threatened plant variety. Firstly, I assessed the association of naturally occurring O. campestris var. davisii with microsite characteristics across three sites. Secondly, I used experimental approaches to investigate the role of microsites in determining translocation success at two life stages: the seedling stage (including germination) and the juvenile stage. Based on previous observations, I hypothesized that the presence of the microsites cobbles and litter (combined) and the microsite cobbles (alone) would serve as predictors for both presence of O. campestris var. davisii at occupied sites and survival of O. campestris var. davisii at recipient sites. Using a combination of generalized mixed linear and logistic models, I found that cobbles and litter (in combination) and cobbles (alone) were strong positive predictors of the presence of Oxytropis campestris var. davisii. I found that post-translocation survival varied by life stage and by microsite type, with higher survival in juvenile plants compared to seedlings. Cobbles and litter (independent of each other) positively predicted juvenile plant survival. There was no evidence to suggest an association between microsite type and seedling survival, perhaps due to low seedling emergence and survival. My study will help guide the development of protocols for translocating this variety and can also serve as a model for other species, for example, by showing how preliminary studies at different life stages can help managers learn the conditions that will favour survival at different life stages, and therefore increase the probability of translocation success.

description: All’uscita della guerra, a Firenze così come in tutto il paese, partiti politici e istituzioni si trovano di fronte ai problemi della ricostruzione, non solo materiale, dell’Italia. Dopo il regime fascista è necessario rieducare gli italiani alla libertà. Il saggio mostra il ruolo della stampa fiorentina, espressione delle forze antifasciste, in questo processo di formazione. Nel 1944-1946, nonostante le divisioni ideologiche e le contrapposizioni fra i partiti, attraverso i giornali sono promossi una nuova identità per la città, centrata sulla memoria della Resistenza, l’invito alla partecipazione alla vita pubblica e alla politica, il rispetto del voto e delle leggi, la condanna della violenza, per diffondere e consolidare i principi della democrazia.

Catasto, fiscalità e lotta politica nella Toscana nel XVIII secolo

description: L’articolo prende in esame i tentativi compiuti nella seconda metà del XvIII secolo dai Lorena – e segnatamente dal granduca riformatore, Pietro Leopoldo- di realizzare nel granducato di Toscana un moderno ed uniforme catasto parti- cellare: quel Granducato che costituisce, com’è noto, uno dei più interessanti e vivaci laboratori o politici di tutto il Settecento europeo. È parso utile tornare su un tema che è stato considerato da svariati autori semplicemente come un caso di ‘riforma fallita’, per cercare di mettere in luce, a seguito anche di nuovi scavi documentari, il ricco quadro delle discussioni e degli schieramenti politici che accompagnarono questo reale o supposto fallimento. Sostanzialmente assente dal dibattito politico negli anni della reggenza lorenese di Francesco Stefano (1737-1765), la questione del catasto emerge all’attenzione nel 1763, ma è con la successione al trono granducale di Pietro Leopoldo che essa diviene il centro di un animato e conflittuale dibattito politico. Sostenuta dalla volontà di riforma del granduca e da un gruppo di suoi collaboratori di orientamento filo-fisiocratico, l’opportunità di procedere ad un complessivo ed uniforme rinnovamento dei catasti pare affermarsi, ed ha inizio dopo molte vivaci discussioni un’intensa sperimentazione in varie parti dello stato. Tuttavia, nonostante i parziali successi ottenuti, l’idea di un nuovo generale catasto viene per molteplici motivi - tra cui primario l’opposizione della classe dei grandi proprietari terrieri fiorentini - abbandonata nel 1785. Ma la vicenda del piccolo laboratorio toscano riflette fedelmente anche il cambiamento di clima del tardo illuminismo europeo. Le difficoltà dell’ assolutismo illuminato, il superamento delle dottrine fisiocratiche ed il diffondersi delle nuove dottrine economiche inglesi concorrono a determinare l’abbandono del progetto di nuovo catasto, che agli occhi dei contempora- nei rappresentava il modello di una società fortemente diretta dallo stato.
