description: Man-made green house gases are the main cause of global warming. Changes in temperature and hence environment are a danger to the survival of the whole planet.Climate change is unprecedented not just for its impact, but also in response to this challenge. Effective climate policies are a great solution to encourage low-carbon resources. This paper evaluates how policymakers can employ carbon taxes to promote a future with more sustainable energy sources.The paper provides an overview of this research background, underlining both urgency for climate action and the need for policy interventions that promote clean and inexpensive alternatives to fossil fuels.It looks into the scientific basis of climate change –how greenhouse gasses become warmer and its anticipated effect on natural and human systems.The core of this paper lies in anthropogenic carbon dioxide taxes, analyzing its main principles, strategies for implementation and the economic logic behind using market forces to check carbon-intense activities.The analysis evaluates various carbon pricing systems, such as cap-and-trade and direct tax structures, and explores their respective advantages, challenges and practical applications in the real world.The impact of carbon taxes is studied comprehensively from economic, environmental and social standpoints. The paper examines potential effects on patterns of energy consumption, investments in low-carbon technologies, job creation, and the overall competitiveness of industries.It also considers the profitability consequences of carbon pricing policies and potentially of measures to lighten regressive effects on vulnerable populations.It sums up main harvests and policy pointer for creation of carbon tax systems that own advantages, covering for their disadvantages, international cooperation. The research paper emphasizes the position of carbon pricing in achieving global climate goals and to a fair low-carbon energy future.

description: Dynamical gluon mass generation has been traditionally plagued with seagull divergences, and all regularization procedures proposed over the years yield finite but scheme-dependent gluon masses. In this work we show how such divergences can be eliminated completely by virtue of a characteristic identity, valid in dimensional regularization. The ability to trigger the aforementioned identity hinges crucially on the particular Ansatz employed for the three-gluon vertex entering into the Schwinger-Dyson equation governing the gluon propagator. The use of the appropriate three-gluon vertex brings about an additional advantage: one obtains two separate (but coupled) integral equations, one for the effective charge and one for the gluon mass. This system of integral equations has a unique solution, which unambiguously determines these two quantities. Most notably, the effective charge freezes in the infrared, and the gluon mass displays power-law running in the ultraviolet, in agreement with earlier considerations.

Subjects: M-GGR/01 Geografia

description: La Nouvelle Géographie Universelle di Élisée Reclus relativizza e problematizza il ruolo dell’Europa e il suo peso nello scacchiere mondiale, restando tuttavia in equilibrio fra, da una parte, la critica delle pratiche coloniali e dall’altra la fiducia nei confronti della tradizione culturale proveniente dall’antica Grecia e dal secolo de Lumi destinata, nella visione evoluzionista dell’autore, a spargere negli altri continenti i germi del pensiero socialista e anarchico. In questo lavoro si cerca di chiarire questa rappresentazione dei concetti di Europa e Occidente in tre passaggi successivi. Dapprima, la ricostruzione della genealogia, della teoria e del contesto storico del concetto di geografia universale all’epoca. Poi, la ricostruzione dalle fonti di archivio delle reti scientifiche di respiro europeo che sono state alla base di quest’opera, indispensabile per poterne comprendere il significato politico nel contesto dell’epoca. Infine, l’indagine sul testo per ricostruire ruolo, caratteri e suddivisione dell’Europa, che si rivela, nonostante la serrata critica del suo ruolo colonizzatore, come il privilegiato laboratorio individuato dai “geografi anarchici” per lo sviluppo delle lotte sociali e per la costruzione, su basi anche geografiche, di una proposta politica federalista e libertaria.
description: This dissertation deals with the representation of Occident and Europe in the Ã�lisÃ©e Reclusâ��s most important work Nouvelle GÃ©ographie Universelle. This works relativizes and problematizes the world role of Europe in that era, balancing the critics of colonialism and the assumption of the universal value of an illuminist cultural heritage, which had to spread, in the authorâ��s views, socialist and anarchist ideas all over the world. We clarify this â��inventionâ�� of Occident and Europe in three successive passages. Firstly, we deal with the genealogical, theoretical and historical concept of a universal geography in the authorâ��s thought. Secondly, we analyse the network of heterodox scientists and militants who collaborated in this encyclopaedic work, to clarify the political and historical relevance of this synergy. Thirdly, we deal with the construction of the concepts of Europe and Occident in the text of the work, contextualising it in the early globalisation of those years. Finally, we stress the importance of geography, and mostly the historical geography of Europe, in the construction of the Reclusâ��s proposal of a European federation, which had to be the first step toward a geographically driven universal federation.

description: We report the detection of outflowing molecular gas in the center of the nearby (z=0.014) massive radio galaxy NGC6328. The radio core of the galaxy, PKS B1718-649, is identified as a Gigahertz Peaked Spectrum source with a compact (2 pc) double radio lobe morphology. We used ALMA CO(2-1) and CO(3-2) observations at 100 pc resolution to study the gas kinematics up to ~5 kpc from the galaxy center. While the bulk of the molecular gas is settled in a highly warped disk, in the inner 300 pc of the disk and along with the orientation of the radio jet, we identified high-excitation and high-velocity gas that cannot be attributed to any regular kinematic component based on our detailed 3D modeling of the ALMA data. The high-velocity dispersion in the gas also suggests that it is not part of an inflowing, shredding structure. These results suggest the presence of a molecular outflow of 3 to 8 solar masses per year. The outflow possibly originated from the interaction of the jet with the dense interstellar medium, even though the radio emission is detected closer to the center than the outflow. In this sense, this source resembles NGC1377, 4C31.04 and ESO420-G13, in which the outflows are linked to faint or past jet activity.

description: El presente trabajo analiza las relaciones entre poder ejecutivo y legislativo en los sistemas presidenciales, concentrándose específicamente en los casos de los primeros gobiernos de Álvaro Uribe Vélez en Colombia [2002-2006] y de Carlos Saúl Menem en Argentina [1989-1995]. Lo hace desde de una perspectiva analítica denominada neomadisoniana. Ubicada bajo el paraguas del neoinstitucionalismo, ésta utiliza como punto de partida el pensamiento de los padres fundadores de la democracia americana, particularmente el de James Madison, concentrándose en el estudio de como los arreglos institucionales constriñen el comportamiento de los actores a través del establecimiento de incentivos mediante los que se distribuyen distintos recursos de poder, proporcionando, además, una estructura estable, aunque no necesariamente eficiente, para la interacción humana. 
De este modo, el enfoque posee un particular interés por el análisis de la organización de los gobiernos, ya sea en términos de jerarquía o de transacciones entre actores instituciones [poderes ejecutivo y legislativo] que, de acuerdo al caso, gozan de distintos niveles de simetría y, consecuentemente, de capacidad de impactar sobre el proceso de toma de decisiones. Dentro de este marco, se intentarán identificar en el análisis de los casos patrones de regularidad y diferencia en relación a las características asumidas en el proceso de separación de poderes y el efecto que ejercen sobre él los poderes constitucionales y partidarios de los presidentes.
Ruolo dei glicosaminoglicani su struttura e funzione dei crimps nei tendini e nei legamenti

description: The biomechanical roles of both tendons and ligaments are fulfilled by extracellular matrix of these tissues. In particular, tension is mainly transmitted and resisted by fibrous proteins (collagen, elastin), whereas compressive load is absorbed by water-soluble glycosaminoglycans (GAGs). GAGs spanning the interfibrillar spaces and interacting with fibrils also seem to play a part in transmitting and resisting tensile stresses. Apart from different functional roles and collagen array, tendons and ligaments share the same basic structure showing periodic undulations of collagen fibers or crimps. Each crimp is composed of many knots of each single fibril or fibrillar crimps. Fibrillar and fiber crimps act as shock absorbers during the initial elongation of both tendons and ligaments and assist the elastic recoil of fibrils and fibers when the tensile stress is removed. The aim of this thesis was to evaluate whether GAGs directly affect the 3D microstructural integrity of fibrillar crimp and fiber crimps in both tendons and ligaments. Achilles tendons and medial collateral ligaments of the knee from eight female Sprague-Dawley rats (90 days old) were digested with chondroitinase ABC to remove GAGs and observed under a scanning electron microscope (SEM). In addition, isolated fibrils from these tissues obtained by mechanical homogenization were analyzed by a transmission electron microscope (TEM). Both samples digested with chondroitinase ABC or mechanically disrupted still showed crimps and fibrillar crimps comparable to tissues with a normal GAGs content. All fibrils in the fibrillar crimp region always twisted leftwards, thus changing their running plane, and then sharply bent, changing their course on a new plane. These data suggest that GAGs do not affect structural integrity or fibrillar crimps functions that seem mainly related to the local fibril leftward twisting and the alternating handedness of collagen from a molecular to a supramolecular level.
Big consequences of small changes (Non-locality and non-linearity of Hartree-Fock equations)

description: It is demonstrated that non-locality and non-linearity of Hartree-Fock equations dramatically affect the properties of their solutions that essentially differ from solutions of Schr?dinger equation with a local potential. Namely, it acquires extra zeroes, has different coordinate asymptotic, violates so-called gauge-invariance, has different scattering phases at zero energy, has in some cases several solutions with the same set of quantum numbers, usually equivalent expressions of current and Green's functions became non-equivalent. These features result in a number of consequences for probabilities of some physical processes, leading e. g. to extra width of atomic Giant resonances and enhance considerably the ionization probability of inner atomic electrons by a strong field.

description: In this thesis we are concerned with the compactness of im-beddings, for unbounded domains, of Orlicz-Sobolev spaces. Donaldson and Trudinger [6] have given a generalization of the Sobolev imbedding theorem and the Rellich-Kondrachov compactness theorem for Sobolev spaces to the case of Orlicz-Sobolev spaces on bounded domains. Clark, Adams, and Fournier [1], [2], [3], and [5] have given extensions of the Sobolev compactness results to certain unbounded domains. In this thesis we consider similar extensions for Orlicz-Sobolev spaces.

description: The AdS/CFT duality has established a mapping between quantities in the bulk AdS black-hole physics and observables in a boundary finite-temperature field theory. Such a relationship appears to be valid for an arbitrary number of spacetime dimensions, extrapolating the original formulations of Maldacena's correspondence. In the same sense properties like the hydrodynamic behavior of AdS black-hole fluctuations have been proved to be universal. We investigate in this work the complete quasinormal spectra of gravitational perturbations of $d$-dimensional plane-symmetric AdS black holes (black branes). Holographically the frequencies of the quasinormal modes correspond to the poles of two-point correlation functions of the field-theory stress-energy tensor. The important issue of the correct boundary condition to be imposed on the gauge-invariant perturbation fields at the AdS boundary is studied and elucidated in a fully $d$-dimensional context. We obtain the dispersion relations of the first few modes in the low-, intermediate- and high-wavenumber regimes. The sound-wave (shear-mode) behavior of scalar (vector)-type low-frequency quasinormal mode is analytically and numerically confirmed. These results are found employing both a power series method and a direct numerical integration scheme.

description: Information security in the context of digital literacy is a digital skill that enables safe and purposeful movement through virtual space. The age limit and frequency of use of the Internet by young generations has been moved back a year due to the COVID-19 pandemic, and the concern for information security of young people is increasingly emphasized. If, and to what extent, knowledge of the issue of identification and authentication affects the information security of high school students aged 16 to 19 in the virtual space, the research question addressed by the authors of this paper was to determine which student behaviors pose a potential danger compromising their information security by establishing a correlation between the variables that determine student behavior and the variables used to examine their level of security in a virtual environment. The research was conducted using a questionnaire on a sample of high school students in the Republic of Croatia, the results of which showed that some students practice behaviors that are potentially dangerous, make them vulnerable and easy targets of cyber predators and attackers, which is why there is cause for concern and a need for a additional education of children of primary and secondary school age in the field of information security in the form of the introduction of the subject Digital Literacy. Based on the results, a model for assessing the level of digital literacy of adolescents that affect information literacy can be designed, but also further related research in the field of information literacy of children and youth can be conducted.

description: We present a method for achieving complete population transfer in a two-state quantum system via adiabatic time evolution in which, contrary to conventional rapid adiabatic passage produced by chirped pulses, there occurs no crossing of diabatic energy curves: there is no sign change of the detuning. Instead, we use structured pulses, in which, in addition to satisfying conditions for adiabatic evolution, there occurs a sign change of the Rabi frequency when the detuning is zero. We present simulations that offer simple geometrical interpretation of the two-dimensional motion of the Bloch vector for this system, illustrating how both complete population inversion and complete population return occur for different choices of structured pulses.
L’impatto degli incentivi sull’efficienza delle imprese manifatturiere

Subjects: SECS-P/02 Politica economica

description: Produttività ed efficienza sono termini comunemente utilizzati per caratterizzare l’abilità di un’impresa nell’utilizzazione delle risorse, sia in ambito privato che pubblico.
Entrambi i concetti sono legati da una teoria della produzione che diventa essenziale per la determinazione dei criteri base con i quali confrontare i risultati dell’attività produttiva e i fattori impiegati per ottenerli. D’altronde, le imprese scelgono di produrre e di investire sulla base delle proprie prospettive di mercato
e di costi dei fattori. Quest’ultimi possono essere influenzati dalle politiche dello Stato che fornisce incentivi e sussidi allo scopo di modificare le decisioni
riguardanti l’allocazione e la crescita delle imprese. In questo caso le stesse imprese possono preferire di non collocarsi nell’equilibrio produttivo ottimo, massimizzando produttività ed efficienza, per poter invece utilizzare tali incentivi.
In questo caso gli stessi incentivi potrebbero distorcere quindi l’allocazione delle risorse delle imprese che sono agevolate.
L’obiettivo di questo lavoro è quello di valutare attraverso metodologie parametriche e non parametriche se incentivi erogati dalla L. 488/92, la principale politica regionale in Italia nelle regioni meridionali del paese nel periodo 1995-2004, hanno avuto o meno effetti sulla produttività totale dei fattori delle imprese agevolate.
Si è condotta una ricognizione rispetto ai principali lavori proposti in letteratura riguardanti la TFP e l’aiuto alle imprese attraverso incentivi al capitale e (in parte) dell’efficienza.
La stima della produttività totale dei fattori richiede di specificare una funzione di produzione ponendo l’attenzione su modelli di tipo parametrico che prevedono, quindi, la specificazione di una determinata forma funzionale relativa
a variabili concernenti i fattori di produzione. Da questa si è ricavata la Total Factor Productivity utilizzata nell’analisi empirica che è la misura su cui viene valutata l’efficienza produttiva delle imprese.
Il campione di aziende è dato dal merge tra i dati della L.488 e i dati di bilancio della banca dati AIDA. Si è provveduto alla stima del modello e si sono approfonditi diversi modelli per la stima della TFP; infine vengono descritti metodi non parametrici (tecniche di matching basate sul propensity score) e metodi parametrici (Diff-In-Diffs) per la valutazione dell’impatto dei sussidi al
capitale.
Si descrive l’analisi empirica condotta. Nella prima parte sono stati illustrati i passaggi cruciali e i risultati ottenuti a partire dalla elaborazione del dataset. Nella
seconda parte, invece, si è descritta la stima del modello per la TFP e confrontate metodologie parametriche e non parametriche per valutare se la politica ha influenzato o meno il livello di TFP delle imprese agevolate.

A total number of 53 Kuiper belt objects and Centaurs have been detected; 25 of which were discovered in this survey. No additional Sedna-like bodies with perihelia beyond 70 AU were found despite a sensitivity to motions out to ~1000 AU. We place constraints on the size and distribution of objects on Sedna orbits.

description: A generalized linear sigma model is employed to study the quark structure of low lying scalar as well as pseudoscalar states. The model allows the possible mixing of quark anti-quark states with others made of two quarks and two antiquarks but no a priori assumption is made about the quark contents of the predicted physical states. Effects of SU(3) symmetry breaking are included. The lighter conventional pseudoscalars turn out to be primarily of two quark type whereas the lighter scalars have very large four quark admixtures.

description: Recently, the stability of certain topological phases of matter under weak perturbations was proven. Here, we present a short, alternate proof of the same result. We consider models of topological quantum order for which the unperturbed Hamiltonian $H_0$ can be written as a sum of local pairwise commuting projectors on a $D$-dimensional lattice. We consider a perturbed Hamiltonian $H=H_0+V$ involving a generic perturbation $V$ that can be written as a sum of short-range bounded-norm interactions. We prove that if the strength of $V$ is below a constant threshold value then $H$ has well-defined spectral bands originating from the low-lying eigenvalues of $H_0$. These bands are separated from the rest of the spectrum and from each other by a constant gap. The width of the band originating from the smallest eigenvalue of $H_0$ decays faster than any power of the lattice size.

description: This paper addresses the task of anomaly diagnosis when the underlying data generation process has a complex spatio-temporal (ST) dependency. The key technical challenge is to extract actionable insights from the dependency tensor characterizing high-order interactions among temporal and spatial indices. We formalize the problem as supervised dependency discovery, where the ST dependency is learned as a side product of multivariate time-series classification. We show that temporal positional encoding used in existing ST transformer works has a serious limitation in capturing higher frequencies (short time scales). We propose a new positional encoding with a theoretical guarantee, based on discrete Fourier transform. We also propose a new ST dependency discovery framework, which can provide readily consumable diagnostic information in both spatial and temporal directions. Finally, we demonstrate the utility of the proposed model, DFStrans (Diagnostic Fourier-based Spatio-temporal Transformer), in a real industrial application of building elevator control.

description: Alexa Skills are used for a variety of daily routines and purposes, but little research has focused on a key part of many people's daily lives: their pets. We present a systematic review categorizing the purposes of 88 Alexa Skills aimed at pets and pet owners and introduce a veterinary perspective to assess their benefits and risks. We present 8 themes of the purposes for Skills aimed at pets and their owners: Calming, Animal Audience, Smart Device, Tracking, Training and Health, Translator, Entertainment/Trivia, and Other - Human Audience. Broadly, we find that these purposes mirror the purposes people have for using Alexa overall, and they largely are supported by veterinary evidence, though caution must be used when Skills relate to animal health. More collaboration between Conversational Agent researchers and animal scientists is called for to better understand the efficacy of using Alexa with pets.

description: We analyse the current build-up of stellar mass within the disks and bulges of nearby galaxies through a comparison of the spatial distributions of forming and old stellar populations. H alpha and R-band imaging are used to determine the distributions of young and old stellar populations in 313 S0a - Im field galaxies out to 40 Mpc. Concentration indices and mean normalised light profiles are calculated as a function of galaxy type and bar classification. The mean profiles and concentration indices show a strong and smooth dependence on galaxy type. Apart from a central deficit due to bulge/bar light in some galaxy types, mean H alpha and R-band profiles are very similar. Mean profiles within a given type are remarkably constant even given wide ranges in galaxy luminosity and size. SBc, SBbc and particularly SBb galaxies have profiles that are markedly different from those of unbarred galaxies. H alpha emission from SBb galaxies is studied in detail; virtually all show resolved central components and concentrations of star formation at or just outside the bar-end radius. In these galaxies, star formation has the same radial distribution as R-band light, i.e. stellar mass is building at approximately constant morphology, with no strong evidence for outer truncation or inside-out disk formation.

Genealogie della legittimità. Città e Stato in Max Weber
Creators: name: Ferraresi, Furio
Publisher: name: Università degli Studi di Firenze
Year: 2014

description: This essay explores the theme of the legitimacy of power in Weber from the standpoints of social science, historical investigation and political reflection. It investigates how Weber develops this theme in Kategorienaufsatz (1913), Soziologische Grundbegriffe (1920), Die Stadt (1911-14) and Politische Schriften (1917-19). Power, as a relationship of command/obedience, is founded on the representations of legitimacy of the individuals involved and on the Einverständnis (consent) which is the condition of possibility of this relationship. It is back to the medieval city that Weber traces the genesis and interweaving of various forms of legitimation, which continue to exist as possibilities even within the modern State. The memory of medieval events re-emerges when Weber, after Germany’s defeat in the First World War and the threat of revolution that followed, tries to lay a foundation for the legitimacy of “leader democracy” by reintroducing the command/obedience relationship between leaders and masses.

description: In an earlier work (arXiv:0808.0953) we established that causal Israel-Stewart viscous hydrodynamics is only accurate in RHIC applications at very low shear viscosities 4 pi eta_s / s < ~ 1.5-2. We show here that the region of applicability is significantly reduced if bulk viscosity plays a role in the dynamics.

Random series of functions and Baire category
Creators: name: Babinchuk, Wayne George
Publisher: name: University of British Columbia
Year: 2010

description: In much of the work done on random series of functions, little attention has been given to the categorical questions that may arise. For example, a common technique is to let ε = {ε [sub n]}[sup ∞ sub n = 0] be a sequence of independent random variables, each taking the values ±1 with probability ½, and to consider the series [sup ∞]∑ [sub n = 0] ε[sub n]c[sub n] cos nt; then one can seek conditions on the coefficients {c[sub n]}[sup ∞ sub n = 0] that almost surely guarantee that the series converges or that it belongs to a certain function space. But one may also ask if this series converges for a set of e of second category or if it belongs to a particular space for such a set of ε. This thesis follows the first seven chapters of J.-P. Kahane's book Some Random Series of Functions and raises these kinds of categorical questions about the topics presented there.

description: We present the results of our new low-resolution spectroscopic observations of the young compact planetary nebula Hb 12 performed in 2011-2020 with SAI MSU telescopes. We have measured the intensities of more than 50 nebular emission lines in the spectral range $λ$3687-9532, detected interstellar absorption features, and conducted a search for absorptions belonging to the possible secondary component of the central star. The extinction coefficient has been estimated from the Balmer decrement to be $c$(H$β$)=1.15$\pm$0.07. The distance has been found by analyzing the interstellar extinction maps to be $D\approx2400$ pc. We have traced the history of the spectroscopic observations of Hb 12, beginning with the first spectra taken by Aller (1951) in 1945. We have detected a systematic increase in the relative intensities of the nebular [O III] $λ$4959 and $λ$5007 lines and a decrease in the relative intensity of the auroral [O III] $λ$4363 line, which has led to an increase in the observed flux ratio $F(λ4959+λ5007)/F(λ4363)$ by a factor of $\sim$4 from 1945 to the present time. The [O III]/[O II] line ratio $F(λ4363)/F(λ3727+ \lambda3729)$ remains constant, suggesting that the degree of ionization, on average, for the nebula is invariable. The temperature of the exciting star has been estimated to be $T\approx41~000$ K. We conclude that a decrease in the electron temperature and, possibly, the electron density in the [O III] line formation region is mainly responsible for the spectroscopic variability.

Cosmological Models Based on a Statistical System of Scalar Charged Degenerate Fermions and an Asymmetric Higgs Scalar Doublet

description: On the basis of the general relativistic statistical and kinetic theory, a consistent closed cosmological model is formulated. It is based on a statistical system of scalar charged fermions interacting by means of classical and phantom scalar fields. Based on the study of the microscopic dynamics of scalar charged particles, within the framework of the Lagrangian as well as Hamiltonian formalism, a function of the dynamic mass of scalar charged particles was constructed and it was shown that for the consistency of the theory, it is necessary to remove the nonnegativity condition for this function. On the basis of the Lagrangian formalism, equations of gravitational and scalar fields with singular sources are formulated and microscopic conservation laws are obtained. Within the framework of the general relativistic kinetic theory, macroscopic equations of gravitational and scalar fields are formulated and macroscopic conservation laws are obtained. These equations' full correspondence to microscopic equations with singular sources is shown. Further, on the basis of the obtained equations, a cosmological model for a degenerate system of scalarly charged fermions is formulated. An exact solution of the constitutive equations for a degenerate scalar-charged plasma in the cosmological model is obtained, which made it possible to significantly simplify the original system of equations. On the basis of the obtained solution of the constitutive equations, two fundamentally different cosmological models are formulated, one of which has two types of singly scalarly charged fermions, while the second has one kind of fermions charged with two charges of various nature. A qualitative analysis of the obtained 6-dimensional dynamic system for a two-component model is carried out.

Gli effetti degli episodi di disoccupazione sulla durata della ricerca di lavoro.
Uno studio sui dati del panel europeo

description: Nel corso degli ultimi venti anni si è assistito ad un incremento generalizzato della disoccupazione in Europa in particolare di quella giovanile: nel 1997 in molti paesi europei il tasso di disoccupazione della classe 15-24 anni è doppio rispetto a quello degli adulti.
Questo lavoro si propone di dare una descrizione realistica del fenomeno della disoccupazione giovanile in Italia come risultante dalle prime 4 waves dell’indagine European Household Community Panel indagando la probabilità di transizione dallo stato di disoccupazione a quello di occupazione. Nell’ambito di un’impostazione legata alla teoria dei processi stocastici e dei dati di durata si indagheranno gli effetti che episodi di disoccupazione precedenti possono avere sulla probabilità di trovare un lavoro, in particolare, nell’ambito di processi stocastici più generali si rilascerà l’ipotesi di semi-markovianità del processo per considerare l’effetto di una funzione della storia passata del processo sulla transizione attuale al lavoro. La stima della funzione di rischio a vari intervalli di durata si dimostra più appropriata quando si tiene conto della storia passata del processo, in particolare, si verifica l’ipotesi che la possibilità di avere successo nella ricerca di un lavoro è negativamente influenzata dall’aver avuto in passato molte transizioni disoccupazione-occupazione-disoccupazione.
