description: C'è lavoro sul web? Si possono distinguere gli utenti della rete dai “lavoratori” ? Quali modalità innovative assume la prestazione digitale? Sono identificabili profili professionali e mestieri tipici del web? L’estrema accessibilità e impersonalità del web è in grado di creare autentiche relazioni di lavoro e di sostenere processi produttivi ? Si possono applicare regole e tutele del lavoro rispetto a pratiche ed esperienze che sfruttano intenzionalmente le caratteristiche di extraterritorialità, autarchia e policentrismo della rete?

Sono questi alcuni dei quesiti sollevati dall'A., nel constatare come la rete, anziché limitarsi a fornire il tramite e il supporto alla circolazione delle informazioni a vantaggio dei tradizionali attori del mercato del lavoro (imprese, lavoratori, agenzie private, servizi pubblici per l’impiego), abbia preferibilmente sviluppato in modo autonomo le proprie potenzialità. Per un verso, il web s’è fatto esso stesso intermediario professionale, sfruttando le sorprendenti capacità dei dispositivi informatici e dei motori di ricerca che propongono su scala globale servizi per il lavoro 2.0; per altro verso, ha favorito la dis-intermediazione nei confronti degli operatori istituzionali (pubblici e privati) attraverso la diffusione di circuiti informali e siti di social recruiting, ma anche di reti civiche finalizzate ad intercettare occasioni lavorative interstiziali.

Inoltre, la rete tende sempre più spesso a scambiare o combinare simultaneamente il ruolo dell’intermediario nel mercato del lavoro e quello del datore di lavoro, rendendo disponibile – almeno in potenza – uno spazio virtuale, ma globale, di esternalizzazione produttiva. L'A. riflette, in particolare, sulla qualificazione giuridica del lavoro digitale mediante crowdsourcing e sulla possibilità di applicare a tale processo gli istituti dell'appalto o della somministrazione di lavoro.

Nonostante il lavoro sul web sia difficile da riconoscere, da misurare e da disciplinare in termini giuridici, è stato osservato da molti che l'utilizzo dei dispositivi tecnologici e dei servizi digitali sembra segnare la rinascita del “mestiere” - nel suo originario e antico significato di pratica di un’arte ed espressione di talento - in netta contrapposizione rispetto all’esercizio delle “professioni” che si sono affermate nell’alto Novecento attraverso un apparato organizzativo pubblico di tipo ordinistico e burocratico. La rete costituisce lo strumento e il supporto del “mestiere” professato dal lavoratore digitale, ma è al contempo l’oggetto e l’obiettivo del mestiere stesso. Mezzo e fine tendono spesso a coincidere.

description: The study of diffusion and low frequency vibrational motions of particles on metal surfaces is of paramount importance; it provides valuable information on the nature of the adsorbate-substrate and the substrate-substrate interactions. In particular, the experimental broadening observed in the diffusive peak with increasing coverage is usually interpreted in terms of a dipole-dipole like interaction among adsorbates via extensive molecular dynamics calculations within the Langevin framework. Here we present an alternative way to interpret this broadening by means of a purely stochastic description, namely the interacting single adsorbate approximation, where two noise sources are considered: (1) a Gaussian white noise accounting for the surface friction and temperature, and (2) a white shot noise replacing the interaction potential between adsorbates. Standard Langevin numerical simulations for flat and corrugated surfaces (with a separable potential) illustrate the dynamics of Na atoms on a Cu(100) surface which fit fairly well to the analytical expressions issued from simple models (free particle and anharmonic oscillator) when the Gaussian approximation is assumed. A similar broadening is also expected for the frustrated translational mode peaks.

description: Gravity and matter are universally coupled, and this unique universality provides us with an intriguing way to quantifying quantum aspects of space-time in terms of the number of gravitons within a given box. In particular, we will provide a limit on the number of gravitons if we trace out the matter degrees of freedom. We will obtain the universal bound on the number of gravitons, which would be given by $N_{g}\approx(m/M_{p})^{2}$. Since the number of gravitons also signify the number of bosonic states they occupy, the number of gravitons will place an indirect constraint on the gravitational entropy of the system. We will show that it saturates Bekenstein bound on the gravitational Area-law of entropy. We will also find that our conclusion is quite robust against the initial state of the matter degrees of freedom. Based on these observations, we will ascertain that the gravitons permeating in the observable Universe always $N_g\gg 1$.

Spinor moving frame, M0-brane covariant BRST quantization and intrinsic complexity of the pure spinor approach

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)

description: To exhibit the possible origin of the inner complexity of the Berkovits's pure spinor approach, we consider the covariant BRST quantization of the D=11 massless superparticle (M0-brane) in its spinor moving frame or twistor-like Lorentz harmonics formulation. The presence of additional twistor-like variables (spinor harmonics) allows us to separate covariantly the first and the second class constraints. After taking into account the second class constraints by means of Dirac brackets and after further reducing the first class constraints algebra, the dynamical system is described by the cohomology of a simple BRST charge associated to the d=1, n=16 supersymmetry algebra. The calculation of the cohomology of this BRST operator requires a regularization which implies the complexification of the bosonic ghost associated to the kappa-symmetry and further leads to a complex (non-Hermitian) BRST charge which is essentially the `pure spinor' BRST operator by Berkovits, but with a composite pure spinor.

description: We study semi-analytically and in a consistent manner, the generation of a mean velocity field $\bar{\mathbf{U}}$ by helical MHD turbulence, and the effect that this field can have on a Mean Field Dynamo. Assuming a prescribed, maximally helical small scale velocity field, we show that large scale flows can be generated in MHD turbulent flows, via small scale Lorentz force. These flows back-react on the mean electromotive force of a Mean Field Dynamo through new terms, leaving the original $α$ and $β$ terms explicitly unmodified. Cross-helicity plays the key role in interconnecting all the effects. In the minimal $τ$ closure that we chose to work with, the effects are stronger for large relaxation times.

description: Warp drives in Einstein's general theory of relativity provide a unique mechanism for manned interstellar travel. It is well-known that the classical superluminal soliton spacetimes require negative energy densities, likely sourced by quantum processes of the uncertainty principle. It has even been claimed by few that negative energy densities are a requirement of superluminal motion. However, recent studies suggest this may not be the case. A general decomposition of the defining variables and the corresponding decomposition of the Eulerian energy are studied. A geometrical interpretation of the Eulerian energy is found, shedding new light on superluminal solitons generated by realistic energy distributions. With this new interpretation, it becomes a relatively simple matter to generate solitonic configurations, within a certain subclass, that respect the positive energy constraint. Using this newfound interpretation, a superluminal solitonic spacetime is presented that possesses positive semi-definite energy. A modest numerical analysis is carried out on a set of example configurations, finding total energy requirements four orders of magnitude smaller than the solar mass. Extraordinarily, the example configurations are generated by purely positive energy densities, a tremendous improvement on the classical configurations. The geometrical interpretation of the Eulerian energy thus opens new doors to generating realistic warp fields for laboratory study and potential future manned interstellar travel.

Compatibility of quantization functors of Lie bialgebras with duality and doubling operations

Year: 2007
Subjects: subject: Quantum Algebra (math.QA)

description: We study the behavior of the Etingof-Kazhdan quantization functors under the natural duality operations of Lie bialgebras and Hopf algebras. In particular, we prove that these functors are "compatible with duality", i.e., they commute with the operation of duality followed by replacing the coproduct by its opposite. We then show that any quantization functor with this property also commutes with the operation of taking doubles. As an application, we show that the Etingof-Kazhdan quantization of some affine Lie superalgebras coincide with their Drinfeld-Jimbo-type quantizations.

Here we focus attention on the property of pseudo-Hermiticity, biorthogonal expansion and pseudo-metric operator. To our knowledge this is the first time that pseudo-Hermiticity is realized explicitly for a nontrivial two-dimensional case. It is shown that the Hamiltonian of the model is not diagonalizable.

description: We study the electronic structures of chiral, Eshelby-twisted van der Waals atomic layers with a particular focus on a chiral twisted graphite (CTG), a graphene stack with a constant twist angle $θ$ between successive layers. We show that each CTG can host infinitely many resonant states which arise from the interaction between the degenerate monolayer states of the constituent layers. Each resonant state has a screw rotational symmetry, and may have a smaller reduced Brillouin zone than other non-resonant states in the same structure. And each CTG can have the resonant states with up to four different screw symmetries. We derive the energies and wave functions of the resonant states in a universal form of a one-dimensional chain regardless of $θ$, and show that these states exhibit a clear optical selection rule for circularly polarized light. Finally, we discuss the uniqueness and existence of the exact center of the lattice and the self-similarity of the wave amplitudes of the resonant states.

We encourage continued study of the abundance patterns of stars with planets to resolve these discrepancies.

The peak line flux density for the CO 5-4 line is $0.72 \pm 0.09$ mJy, with a line FWHM = $610 \pm 110$ km s$^{-1}$. The implied molecular gas mass is $(1.6 \pm 0.3) \times 10^{10}$ M$_\odot$. We also detect the 90 GHz continuum at $0.12 \pm 0.03$ mJy, consistent with a 47K dust spectrum extrapolated from higher frequencies. J0927+2001 is the second example of a huge molecular gas reservoir within the host galaxy of a quasar within 1 Gyr of the big bang. Observations of J0927+2001 are consistent with a massive starburst coeval with a bright quasar phase in the galaxy, suggesting the rapid formation of both a super-massive black hole through accretion, and the stellar host spheroid, at a time close to the end of cosmic reionization.

description: Authorization protects application resources by allowing only authorized entities to access them. Existing authorization solutions are widely based on the request-response model, where a policy enforcement point intercepts application requests, obtains authorization decisions from a remote policy decision point, and enforces those decisions. This model enables sharing the decision point as an authorization service across multiple applications. But, with many requests and resources, using a remote shared decision point leads to increased latency and presents the risk of introducing a bottleneck and/or a single point of failure. This dissertation presents three approaches to addressing these problems. The first approach introduces and evaluates the mechanisms for authorization recycling in role-based access control systems. The algorithms that support these mechanisms allow a local secondary decision point to not only reuse previously-cached decisions but also infer new and correct decisions based on two simple rules, thereby masking possible failures of the central authorization service and reducing the network delays. Our evaluation results suggest that authorization recycling improves the availability and performance of distributed access control solutions. The second approach explores a cooperative authorization recycling system, where each secondary decision point shares its ability to make decisions with others through a discovery service. Our system does not require cooperating secondary decision points to trust each other. To maintain cache consistency at multiple secondary decision points, we propose alternative mechanisms for propagating update messages. Our evaluation results suggest that cooperation further improves the availability and performance of authorization infrastructures. The third approach examines the use of a publish-subscribe channel for delivering authorization requests and responses between policy decision points and enforcement points. By removing enforcement points' dependence on a particular decision point, this approach helps improve system availability, which is confirmed by our analytical analysis, and reduce system administration/development overhead. We also propose several subscription schemes for different deployment environments and study them using a prototype system. We finally show that combining these three approaches can further improve the authorization system availability and performance, for example, by achieving a unified cooperation framework and using speculative authorizations.

description: Small angle neutron scattering (SANS) is used to measure the density of heavy water contained in 1-D cylindrical pores of mesoporous silica material MCM-41-S-15, with pores of diameter of 15+-1 A. In these pores the homogenous nucleation process of bulk water at 235 K does not occur and the liquid can be supercooled down to at least 160 K. The analysis of SANS data allows us to determine the absolute value of the density of D2O as a function of temperature. We observe a density minimum at 210+-5 K with a value of 1.041+-0.003 g/cm3. We show that the results are consistent with the predictions of molecular dynamics simulations of supercooled bulk water. This is the first experimental report of the existence of the density minimum in supercooled water.

Convergence estimates are obtained in the case of strong convexity and its absence, and a stopping criterion is proposed for not strongly convex problems.

description: We introduce the class of {\em strongly Rayleigh} probability measures by means of geometric properties of their generating polynomials that amount to the stability of the latter. This class covers important models such as determinantal measures (e.g. product measures, uniform random spanning tree measures) and distributions for symmetric exclusion processes. We show that strongly Rayleigh measures enjoy all virtues of negative dependence and we also prove a series of conjectures due to Liggett, Pemantle, and Wagner, respectively. Moreover, we extend Lyons' recent results on determinantal measures and we construct counterexamples to several conjectures of Pemantle and Wagner on negative dependence and ultra log-concave rank sequences.

description: In order to predict and analyze turbulent transport in tokamaks, it is important to model transport that arises from microinstabilities. For this task, quasilinear codes have been developed that seek to calculate particle, angular momentum, and heat fluxes both quickly and accurately. In this tutorial, we present a derivation of one such code known as QuaLiKiz, a quasilinear gyrokinetic transport code. The goal of this derivation is to provide a self-contained and complete description of the underlying physics and mathematics of QuaLiKiz from first principles. This work serves both as a comprehensive overview of QuaLiKiz specifically as well as an illustration for deriving quasilinear models in general.

Usable Security

description: Evaluating the usability of specific information technology (IT) security tools is challenging. For example, laboratory experiments can have little validity due to the complexity of real-world security problems and the need to situate a specific tool within a larger context. However, it is difficult to recruit IT security practitioners for simple interviews, let alone field observations. Direct observation of tool use can be time consuming as much security work is spontaneous (e.g. security incident response) or occurs over many months (e.g., deploying an identity management system). As ITSM tool use is intrinsically cooperative, its study inherits the difficulties of studying cooperation. As a result, heuristic evaluation of ITSM tools could be a viable component of tool usability evaluations.

description: We describe a method for obtaining analytic solutions corresponding to exact marginal deformations in open bosonic string field theory. For the photon marginal deformation we have an explicit analytic solution to all orders. Our construction is based on a pure gauge solution where the gauge field is not in the Hilbert space. We show that the solution itself is nevertheless perfectly regular. We study its gauge transformations and calculate some coefficients explicitly. Finally, we discuss how our method can be implemented for other marginal deformations.

description: Ο δημόσιος τομέας ευθύνεται για την ομαλή λειτουργία του κράτους, την δημοσίευση νόμων, την φροντίδα των πολιτών και τον έλεγχο της εθνικής οικονομίας μιας χώρας. Στην Ελλάδα, μετά την εμφάνιση της κρίσης και την επιβολή των διαδοχικών μνημονίων, ο δημόσιος τομέας έχει υποστεί πολλές αλλαγές. Οι αλλαγές αυτές αφορούσαν μεταξύ άλλων και στις μειώσεις θέσεων εργασίας, αυξήσεις φόρων, κατάργηση φοροαπαλλαγών αλλά και την διαμόρφωση του μισθολογίου των δημοσίων υπαλλήλων.
Στην παρούσα διπλωματική εργασία, αναλύεται το σύστημα αμοιβών στο δημόσιο τομέα σύμφωνα με το Ενιαίο Μισθολόγιο, όπως προβλέπεται από το Ν.4354/2015, αλλά και των ειδικών κατηγοριών σύμφωνα με Ν. 4472/2017. Σκοπός της παρούσας εργασίας θα είναι να διερευνηθεί κατά πόσο δίκαια έχουν διαμορφωθεί οι μισθοί. Είναι σημαντικό να διαπιστώσουμε το κατά πόσο αντικειμενικά έχουν καθοριστεί τα μισθολογικά κλιμάκια για κάθε βαθμίδα εκπαίδευσης, σε συνδυασμό με τις απαιτήσεις και τα προσόντα που απαιτούνται.

description: Social interactions and personal tastes shape our consumption behavior of cultural products. In this study, we present a computational model of a cultural market and we aim to analyze the behavior of the consumer population as an emergent phenomena. Our results suggest that the final market shares of cultural products dramatically depend on consumer heterogeneity and social interaction pressure. Furthermore, the relation between the resulting market shares and social interaction is robust with respect to a wide range of variation in the parameter values and the type of topology.

description: It has been recently shown that the halo near the Sun contains several kinematic substructures associated to past accretion events. For the more distant halo, there is evidence of large-scale density variations -- in the form of stellar clouds or overdensities. We study the link between the local halo kinematic groups and three of these stellar clouds: the Hercules-Aquila cloud, the Virgo Overdensity, and the Eridanus-Phoenix overdensity. We perform orbital integrations in a standard Milky Way potential of a local halo sample extracted from Gaia eDR3, with the goal of predicting the location of the merger debris elsewhere in the Galaxy. We specifically focus on the regions occupied by the three stellar clouds and compare their kinematic and distance distributions with those predicted from the orbits of the nearby debris. We find that the local halo substructures have families of orbits that tend to pile up in the regions where the stellar clouds have been found. The distances and velocities of the cloud's member stars are in good agreement with those predicted from the orbit integrations, particularly for Gaia-Enceladus stars. This is the dominant contributor of all three overdensities, with a minor part stemming from the Helmi streams and to an even smaller extent from Sequoia. The orbital integrations predict no asymmetries in the sky distribution of halo stars, and they pinpoint where additional debris associated with the local halo substructures may be located.

description: Contemporary business innovation relies increasingly on information and communications technology (ICT) solutions. As ICT initiatives are generally implemented via projects the management of ICT projects has come under increasing scrutiny. ICT projects continue to fail; as a result, while research in ICT project management has indeed increased, many challenges for research and practice remain. Many studies have addressed the execution and management of ICT projects and the many factors that might relate to project outcomes. Very few, however, have considered ICT project initiation and the crucial decisions made at that very early, pre-life cycle stage. The primary intent of this research is therefore to investigate ICT projects with a particular focus on their initiation. In doing so we wished to understand why ICT projects are started, and how they are moved from idea or proposal to supported reality. A combination of semi-structured interviews and the repertory grid data collection and analysis method was employed to investigate and validate the motivating factors that influence individual IT Managers' project initiation decisions and the methods they use to transition from idea to enacted project. Our results showed that there are indeed multiple underlying reasons for the decisions made at this early stage and that there are some especially common decision drivers. Some were expected, in the sense that they mapped to recommended best practice. For instance, most projects are motivated by a desire to achieve efficiencies or cost savings, and their potential tends to be assessed using cost benefit analysis. Other results were more surprising - competitor pressure was not a common driver for ICT project initiation in our analysis. Unsurprisingly, formal evaluation methods are more frequently used to assess project proposals when those projects are larger and higher profile. (Abridged)

description: The present study was aimed at elucidating the epidemiology of sepsis, with a special emphasis on identifying the common bacterial aetiology, proportion of infections caused by multi-drug resistant (MDR) bacteria, and risk factors associated with 28-day mortality at a university hospital in South India. A prospective study was undertaken from January 2017 to March 2018. Adult patients with the diagnosis of sepsis requiring intensive care unit (ICU) care were recruited. Baseline clinical, epidemiological, and laboratory data were recorded, and their association with 28-day mortality was assessed using logistic regression models. 400 subjects with a qSOFA score ≥2 at the time of ICU admission were included in the study. The mean age was 55.7 ± 16.6 years, and 69% were males. The mean SOFA score at the time of admission was 9.9 ± 2.7. Bacterial aetiology of sepsis was established in 53.5% of cases and 24% were caused by MDR pathogens. Carbapenem resistance was observed in 37% of the Gram-negative isolates. Escherichia coli (34.1%) was the leading pathogen. Overall, the 28-day mortality in ICU was 40%. 38% died within 48 h of ICU admission. Hypertension and SOFA > 9, male gender, and baseline-creatinine values >2.4 mg/dl were risk factors for mortality. Male gender, hypertension, SOFA > 9, and increased creatinine were identified as the predictors for mortality. Infectious aetiology remained undetected in nearly half of the cases using routine microbiology culture methods. Mortality within the first 48 h of admission to ICU is high and prompts the need for increasing awareness about early sepsis diagnosis in community health care settings.

description: Context: The counts of galaxies and AGN in the mid infra-red (MIR) bands are important instruments for studying their cosmological evolution. However, the classic spectral line ratios techniques can become misleading when trying to properly separate AGN from starbursts or even from apparently normal galaxies. Aims: We use X-ray band observations to discriminate AGN activity in previously classified MIR-selected starburst galaxies and to derive updated AGN1 and (Compton thin) AGN2 counts at 15 um. Methods: XMM observations of the ELAIS-S1 15um sample down to flux limits ~2x10^-15 erg cm^-2 s^-1 (2-10 keV band) were used. We classified as AGN all those MIR sources with a unabsorbed 2-10 keV X-ray luminosity higher that ~10^42 erg/s. Results: We find that at least about 13(+/-6) per cent of the previously classified starburst galaxies harbor an AGN. According to these figures, we provide an updated estimate of the counts of AGN1 and (Compton thin) AGN2 at 15 um. It turns out that at least 24% of the extragalactic sources brighter than 0.6 my at 15 um are AGN (~13% contribution to the extragalactic background produced at fluxes brighter than 0.6 mJy).

description: We consider the discrete time quantum random walks on a Sierpinski gasket. We study the hitting probability as the level of fractal goes to infinity in terms of their localization exponents $β_w$ , total variation exponents $δ_w$ and relative entropy exponents $η_w$ . We define and solve the amplitude Green functions recursively when the level of the fractal graph goes to infinity. We obtain exact recursive formulas for the amplitude Green functions, based on which the hitting probabilities and expectation of the first-passage time are calculated. Using the recursive formula with the aid of Monte Carlo integration, we evaluate their numerical values. We also show that when the level of the fractal graph goes to infinity, with probability 1, the quantum random walks will return to origin, i.e., the quantum walks on Sierpinski gasket are recurrent.

description: O σκοπός της παρούσας πραγματείας είναι η προβολή της κύριας θεολογικής ιδέας και του κεντρικού θεολογικού μηνύματος των κειμένων του π. Δημητρίου Στανιλοάε. Όλη η θεολογική του παρακαταθήκη, καθώς ο ίδιος ομολογεί, σχετίζεται με το δίπτυχο – πρόσωπο και κοινωνία. Εξάλλου, αυτή είναι η θεολογική μαρτυρία, την οποία ο π. Στανιλοάε ήθελε να περάσει στον σύγχρονο άνθρωπο. Επομένως, η παρούσα διατριβή προσπαθεί σε γενικές γραμμές να προτάξει την θεολογική σκέψη του π. Στανιλοάε περί του προσώπου. Πιστεύουμε ότι μια τέτοια έρευνα θα μπορούσε να συμβάλει στη σωστή αντίληψη της ανθρωπολογικής αξίας του ανθρώπου και να συντελέσει στον πνευματικό αναπροσανατολισμό του.
description: The aim of the present paper was the study of the principal theological idea and of the central theological message of Father Staniloae’s writings. All of his theology, like the Father says, is based on two points of view – person and communion. With all that, this is the theological witness that Father Staniloae wanted to give to the modern people. So, this writing tries literally to offer the theological idea of Father’s Staniloae beyond the person. We think that this kind of research could contribute in right understanding of the anthropological value of men and help in his spiritual reorientation.

description: We consider the bosonic sector of a N=2 supersymmetric Chern-Simons-Higgs theory in 2+1 dimensions. The gauge group is U(1)xU(N) and has N_f flavors of fundamental matter fields. The model supports non-Abelian (axially symmetric) vortices when N_f\geq N, which have internal (orientational) moduli. When N_f > N, the solutions acquire additional collective coordinates parameterizing their transverse size. We solve the BPS equations numerically and obtain local (N_f = N) and semi-local (N_f > N) string solutions.

description: Two new expanding X-ray rings were detected by the Swift XRT instrument during early follow-up observations of GRB 061019 and GRB 070129, increasing to 5 the number of dust scattering X-ray halos observed around GRBs. Although these two halos were particularly faint, a sensitive analysis can be performed that optimizes the method originally developed by Tiengo & Mereghetti (2006) to analyze dust scattering rings observed with XMM-Newton for the Swift satellite. In the case of GRB 061019, a known giant molecular cloud is identified as the one responsible for the scattering process, and its distance is accurately measured (d=940$\pm$40 pc) through the dynamics of the expanding ring. In the second case, XRT observed both the main peak of the prompt emission of GRB 070129 and the scattering halo, but the small number of detected halo photons prevents us from distinguish between different dust models.
