description: Serpentinization and carbonation of ultramafic formations is a ubiquitous phenomenon, which deeply influences the biogeochemical cycles of water, hydrogen, carbon... while supporting the particular biosphere around the oceanic hydrothermal vents. Carbonation of peridotites and other mafic and ultramafic rocks is also a hot topic in the current energy landscape as the engineered sequestration of mineral CO2 in these formations could help reduce the atmospheric emissions and cope with climate change. In this study, we present two reactive percolation experiments performed on a natural serpentinite dredged from the ultraslow South-West Indian Oceanic Ridge. The serpentinite cores (length 3-4 cm and dia. 5.6 mm) were subjected for about 10 days to the continuous injection of a NaHCO3-saturated brine at respectively 160°C and 280°C. Petrographic and petrophysical results as well as outlet fluid compositions were compared to numerical batch simulations performed with the PHREEQC open software allowing to reconstruct the mineralogical evolution of both cores. The most striking observation is the fast and dramatic decrease of the permeability for both experiments principally due to the precipitation of carbonates. On the contrary, serpentine was found to be less impacting as it precipitates in low-flow zones, out of the main percolation paths. In total, about 5.6% of the total injected CO2 was retained in the core, at 280°C. In the same time, hydrogen was consistently produced with a total recovered H2 corresponding to 0.8% of the maximum H2 possible. The global behavior of the cores is interpreted as the result from an interplay between interacting spatio-temporal lengthscales controlled by the Damkohler number.

description: The 100-m Robert C. Byrd Green Bank Telescope (GBT) and the Owens Valley Radio Observatory (OVRO) 40-m radio telescope have been used to conduct a survey of 3165 known extragalactic radio sources over 143 square degrees of the sky. Target sources were selected from the NRAO VLA Sky Survey in fields observed by the Cosmic Background Imager (CBI); most are extragalactic active galactic nuclei (AGN) with 1.4 GHz flux densities of 3 to 10 mJy. The resulting 31 GHz catalogs are presented in full online. Using a Maximum-Likelihood analysis to obtain an unbiased estimate of the distribution of the 1.4 to 31 GHz spectral indices of these sources, we find a mean 31 to 1.4 GHz flux ratio of 0.110 +/- 0.003 corresponding to a spectral index of alpha=-0.71 +/- 0.01 (S ~ nu^alpha); 9.0 +/- 0.8 % of sources have alpha > -0.5 and 1.2 +/- 0.2 % have alpha > 0. By combining this spectral index distribution with 1.4 GHz source counts we predict 31 GHz source counts in the range 1 mJy < S_31 < 4 mJy, N(>S_31) = (16.7 +/- 1.7) deg^2 (S_31/1 mJy)^(-0.80 +/- 0.07). We also assess the contribution of mJy-level (S_1.4 < 3.4 mJy) radio sources to the 31 GHz CMB power spectrum, finding a mean power of ell (ell+1) C^src_ell/(2 pi) = 44 +/- 14 micro-Kelvin^2 and a 95% upper limit of 80 micro-Kelvin^2 at ell = 2500. Including an estimated contribution of 12 micro-Kelvin^2 from the population of sources responsible for the turn-up in counts below S_1.4 = 1 mJy this amounts to 21 +/- 7 % of what is needed to explain the CBI high-ell excess signal, 275 +/- 63 micro-Kelvin^2. These results are consistent with other measurements of the 31 GHz point source foreground.
description: Replace with accepted version, incorporating referee comments. Significant revisions for clarity, added comparison to recent results. Quoted error bars on source counts are larger and the range of validity more limited; results on CBI excess unchanged

description: We study possible effects of a light CP-odd Higgs boson on radiative Upsilon decays in the Next-to-Minimal Supersymmetric Standard Model. Recent constraints from CLEO on radiative Upsilon(1S) decays are translated into constraints on the parameter space of CP-odd Higgs boson masses and couplings, and compared to constraints from B physics and the muon anomalous magnetic moment. Possible Higgs - eta_b(nS) mixing effects are discussed, notably in the light of the recent measurement of the eta_b(1S) mass by Babar: The somewhat large Upsilon(1S) - eta_b(1S) hyperfine splitting could easily be explained by the presence of a CP-odd Higgs boson with a mass in the range 9.4 - 10.5 GeV. Then, tests of lepton universality in inclusive radiative Upsilon decays can provide a visible signal in forthcoming experimental data.

description: In the present thesis, I discuss the role of orality in translation, taking into account the problems arising while translating Russian folk epics. I investigate the meaning of orality in the context of folkloristic translation, trying to define a concept of oral poetry, and exploring its consequences for translation. In the first chapter, I try to identify the main differences between written literature and oral modes of expression, with special reference to folklore. Oral verbal art is performed, sung or recited, and based on a vital and dynamic interrelation between kinesics, sound, speech and gestures. According to Muhawi (2006), performance provides an interpretive frame enabling a correct interpretation of the message conveyed beyond the literal meaning. Transposing certain performance elements into print is one of the most controversial problems in folklore studies. However, formulas and formal stylistic devices may be rendered in transcription, building a bridge between oral and written elements. In the translation of oral poetry in transcription, this interconnection between orality and literacy might be emphasized, thus creating a hybrid dimension where oral and literary features coexist. In the second chapter, I introduce and describe the genre of Russian folk epics, transmitted orally, and transcribed between the 19th and 20th centuries, from a historical, linguistic and stylistic point of view. In the third and fourth chapters, I explore the issue of translation of Russian oral poetry. I first analyse existing Italian translations of Russian epics, and then present and discuss my own translation, based on a philological, scholarly approach. Thus, in my translation, which is followed by a rich commentary, I try to focus on the rendering of formulas as one of the most relevant aspects of Russian epics. At the same time, oral devices combine with literary features, thus creating a sort of frozen orality.
Microstructure engineering of metamagnetic Ni-Mn-based Heusler compounds by Fe-doping: A roadmap towards excellent cyclic stability combined with large elastocaloric and magnetocaloric effects

description: Ni-Mn-based metamagnetic shape-memory alloys exhibit a giant thermal response to magnetic fields and uniaxial stress which can be utilized in single caloric or multicaloric cooling concepts for energy-efficient and sustainable refrigeration. However, during cyclic operation these alloys suffer from structural and functional fatigue as a result of their high intrinsic brittleness. Here, we present based on Fe-doping of Ni-Mn-In a microstructure design strategy which simultaneously improves cyclic stability and maintains the excellent magnetocaloric and elastocaloric properties. Our results reveal that precipitation of a strongly Fe-enriched and In-depleted coherent secondary gamma-phase at grain boundaries can ensure excellent mechanical stability by hindering intergranular fracture during cyclic loading. In this way, a large elastocaloric effect of -4.5 K was achieved for more than 16000 cycles without structural or functional degradation, which corresponds to an increase of the cyclic stability by more than three orders of magnitude as compared to single-phase Ni-Mn-In-(Fe). In addition, we demonstrate that the large magnetocaloric effect of single-phase Ni-Mn-In-(Fe) can be preserved in the dual-phase material when the secondary gamma-phase is exclusively formed at grain boundaries as the martensitic transformation within the Heusler matrix is barely affected. This way, an adiabatic temperature change of -3 K and an isothermal entropy change of 15 $Jkg^{-1}K^{-1}$ was obtained in 2 T for dual-phase Ni-Mn-In-Fe. We expect that this concept can be applied to other single caloric and mutlicaloric materials, therewith paving the way for solid-state caloric cooling applications.

description: We analyze a model of Semi-Direct Gauge Mediation in which the hidden sector is the 4-1 model and the messenger fields are charged under the U(1) gauge group. At tree level, the SUSY-breaking F-terms induce D-terms from which SUSY-split messenger masses arise. We calculate these masses by three complementary methods. Additionally, we compute the one-loop corrections to the masses. We consider this model both with and without a Fayet-Iliopoulos term for the hidden sector U(1). Finally, we write down a simple model of Minimal Gauge Mediation in which the only scale is dynamically generated.

description: Transfer-matrix methods are used, in conjunction with finite-size scaling and conformal invariance concepts, to generate an accurate phase diagram for a two-dimensional square-lattice Ising spin-1/2 magnet, with couplings which are positive along one coordinate axis, and negative along the other, in a uniform external field. Our results indicate that the critical line starts horizontally at the zero-temperature end of the phase boundary, at variance with the reentrant behavior predicted in some earlier studies. Estimates of the thermal scaling exponent are very close to the Ising value $y_T=1$ along the critical line, except near T=0 where strong crossover effects prevent a reliable analysis.

description: In the last few years, we saw libraries across the world take on key roles in driving research initiatives (Lang, L., et al., 2018), led to the creation of research support positions and the role of liaison librarians has also shifted. The IATUL Special Interest Group – Metrics and Research Impact (SIG-MaRI) recognised the lack of formal training and development programme to upskill staff transitioning into research support roles. It has been, and still is a challenge faced by many SIG-MaRI members. University of New South Wales (UNSW) Library launched the 10 Research Impact Things in 2019, which aimed to develop foundational skills in research impact across the Library based on the bibliometric capabilities framework (Cox, A., et al, 2017). The IATUL SIG-MaRI adapted and significantly revised the UNSW programme for the broader IATUL members as a self-paced training and development tool. The session will be presented by Shiobhan Smith, Librarian at Research Support Unit Manager at the University of Otago (@ShiobhanSmith), and is is organised by the Evaluation and Metrics special interest group from the European Association for Health Information and Libraries (EAHIL).

description: A method combining photogrammetry with ballistic analysis is demonstrated to identify flying debris in a rocket launch environment. Debris traveling near the STS-124 Space Shuttle was captured on cameras viewing the launch pad within the first few seconds after launch. One particular piece of debris caught the attention of investigators studying the release of flame trench fire bricks because its high trajectory could indicate a flight risk to the Space Shuttle. Digitized images from two pad perimeter high-speed 16-mm film cameras were processed using photogrammetry software based on a multi-parameter optimization technique. Reference points in the image were found from 3D CAD models of the launch pad and from surveyed points on the pad. The three-dimensional reference points were matched to the equivalent two-dimensional camera projections by optimizing the camera model parameters using a gradient search optimization technique. Using this method of solving the triangulation problem, the xyz position of the object's path relative to the reference point coordinate system was found for every set of synchronized images. This trajectory was then compared to a predicted trajectory while performing regression analysis on the ballistic coefficient and other parameters. This identified, with a high degree of confidence, the object's material density and thus its probable origin within the launch pad environment. Future extensions of this methodology may make it possible to diagnose the underlying causes of debris-releasing events in near-real time, thus improving flight safety.

description: The aim of this research is to estimate the impact of violent film excerpts on university
students (30 f, 30 m) in two different sequences, a “justified” violent scene followed by an
“unjustified” one, or vice versa, as follows:
1) before-after sequences, using Aggressive behaviour I-R Questionnaire, Self Depression
Scale and ASQ-IPAT Anxiety SCALE;
2) after every excerpt, using a self-report to evaluate the intensity and hedonic tone of
emotions and the violence justification level.
Emotion regulation processes (suppression, reappraisal, self-efficacy) were considered.
In contrast with the “unjustified” violent scene, during the “justified” one, the justification
level was higher; intensity and unpleasantness of negative emotions were lower.
Anxiety (total and latent) and rumination diminished after both types of sequences.
Rumination decreases less after the JV-UV sequence than after the UV-JV sequence.
Self-efficacy in controlling negative emotions reduced rumination, whereas suppression
reduced irritability.
Reappraisal, self-efficacy in positive emotion expression and perceived emphatic selfefficacy
did not have any effects.

description: We use deep archival Chandra and XMM-Newton observations of three of the brightest cluster-centre radio galaxies in the sky, Cygnus A, Hercules A and Hydra A, to search for inverse-Compton emission from the population of electrons responsible for the low-frequency radio emission. Using simulated observations, we derive robust estimates for the uncertainties on the normalization of an inverse-Compton component in the presence of the variations in background thermal temperature actually seen in our target objects. Using these, together with the pressures external to the lobes, we are able to place interesting upper limits on the fraction of the energy density in the lobes of Hydra A and Her A that can be provided by a population of relativistic electrons with standard properties, assuming that the magnetic field is not dominant; these limits are consistent with the long-standing idea that the energy density in these lobes is dominated by a non-radiating particle population. In Cygnus A, we find evidence in the spectra for an additional hard component over and above the expected thermal emission, which is plausibly a detection of inverse-Compton emission; even in this case, though, some additional non-radiating particles and/or a departure from our standard assumptions on the electron spectrum are necessary to allow pressure balance at the mid-point of the lobes. As this is not the case in other Fanaroff-Riley class II radio galaxies, we suggest that the rich environment of Cygnus A may have some effect on its lobe particle content.

Studio cinematico dell'articolazione del gomito e valutazione del carrying angle durante l'esercizio fisico
Creators: name: Zampagni, Maria Luisa <1966>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2007
Subjects: BIO/09 Fisiologia

description: Questo progetto di ricerca, è stato sviluppato per studiare le caratteristiche anatomofunzionali che definiscono l’articolazione del gomito, ed in modo articolare la presenza dell’angolazione valga che origina dalla diversa orientazione degli assi meccanici dell’avambraccio e del braccio e, denominata in letteratura come carrying angle.
L’obiettivo principale di questo lavoro - meglio espresso nei diversi capitoli - è stato, quello di identificare un nuovo approccio di misura per la stima di questo angolo,
utilizzabile sia per gli studi di biomeccanica articolare, che per gli studi di analisi del movimento per l’arto superiore.
Il primo obiettivo è stato quello di scegliere un algoritmo di calcolo che rispettasse le caratteristiche dell’articolazione, ed in modo particolare abile a minimizzare gli errori introdotti sia nella fase di acquisizione dei punti di repere anatomici, che in quella legata alla predizione del movimento di flesso-estensione, con un modello matematico.
Per questo motivo abbiamo dovuto realizzare una serie di misure in un primo tempo su due cadaveri di arto superiore, poi, seguendo le regole classiche per la validazione dell’approccio metodologico adottato, si sono realizzate misure in-vivo, prima in massima estensione e poi durante il movimento.
Inizialmente abbiamo pensato di comparare le misure lineari relative alle ampiezze del braccio (ampiezza tra l’epicondilo laterale e mediale) e dell’avambraccio (ampiezza tra lo stiloide ulnare e radiale) con quelle ottenute mediante un antropometro; successivamente
dopo aver verificato la ripetibilità tra i diversi operatori nell’ acquisizione dei punti di repere anatomici con il digitalizzatore Faro Arm, abbiamo comparato le
misure ottenute relative al carrying angle con quelle di un goniometro standard, classicamente utilizzato nella pratica clinica per la definizione dei range di movimento
dell’arto superiore.
Infine, considerando la bontà delle misure ottenute, abbiamo riproposto tale metodologia con stumenti stereofotogrammetrici per l’analisi del movimento (VICON System), ottenendo la stessa stabilit`a nell’andamento del carrying angle in funzione della flessione, sia come riportato dagli studi in letteratura, sia come riscontrato nel nostro studio in-vitro.
In conclusione, questo lavoro di ricerca ha evidenziato (sia per i risultati ottenuti, che per la elevata numerosità dei soggetti testati), come gli esseri umani presentino una grande variabilità individuale nel valore di questo angolo, e di come questo possa aiutare per la corretta definizione di un modello 3-D dell’arto superiore.
Pertanto, gli studi futuri sulla biomeccanica dell’arto superiore dovrebbero includere sempre la valutazione di questa misura.

description: We have measured the trapping lifetime of magnetically trapped atoms in a cryogenic atom-chip experiment. An ultracold atomic cloud is kept at a fixed distance from a thin gold layer deposited on top of a superconducting trapping wire. The lifetime is studied as a function of the distances to the surface and to the wire. Different regimes are observed, where loss rate is determined either by the technical current noise in the wire or the Johnson-Nyquist noise in the metallic gold layer, in good agreement with theoretical predictions. Far from the surface, we observe exceptionally long trapping times for an atom-chip, in the 10-minutes range.

Stochastic dynamics of phase-slip trains and superconductive-resistive switching in current-biased nanowires

description: Superconducting nanowires fabricated via carbon-nanotube-templating can be used to realize and study quasi-one-dimensional superconductors. However, measurement of the linear resistance of these nanowires have been inconclusive in determining the low-temperature behavior of phase-slip fluctuations, both quantal and thermal. Thus, we are motivated to study the nonlinear current-voltage characteristics in current-biased nanowires and the stochastic dynamics of superconductive-resistive switching, as a way of probing phase-slip events. In particular, we address the question: Can a single phase-slip event occurring somewhere along the wire--during which the order-parameter fluctuates to zero--induce switching, via the local heating it causes? We explore this and related issues by constructing a stochastic model for the time-evolution of the temperature in a nanowire whose ends are maintained at a fixed temperature. We derive the corresponding master equation as tool for evaluating and analyzing the mean switching time at a given value of current. The model indicates that although, in general, several phase-slip events are necessary to induce switching via a thermal runaway, there is indeed a regime of temperatures and currents in which a single event is sufficient. We carry out a detailed comparison of the results of the model with experimental measurements of the distribution of switching currents, and provide an explanation for the counter-intuitive broadening of the distribution width that is observed upon lowering the temperature. Moreover, we identify a regime in which the experiments are probing individual phase-slip events, and thus offer a way for exploring the physics of nanoscale quantum tunneling of the superconducting order parameter.

description: We give a description of the design, construction and testing of the 30 and 44 GHz Front End Modules (FEMs) for the Low Frequency Instrument (LFI) of the Planck mission to be launched in 2009. The scientific requirements of the mission determine the performance parameters to be met by the FEMs, including their linear polarization characteristics. The FEM design is that of a differential pseudo-correlation radiometer in which the signal from the sky is compared with a 4-K blackbody load. The Low Noise Amplifier (LNA) at the heart of the FEM is based on indium phosphide High Electron Mobility Transistors (HEMTs). The radiometer incorporates a novel phase-switch design which gives excellent amplitude and phase match across the band. The noise temperature requirements are met within the measurement errors at the two frequencies. For the most sensitive LNAs, the noise temperature at the band centre is 3 and 5 times the quantum limit at 30 and 44 GHz respectively. For some of the FEMs, the noise temperature is still falling as the ambient temperature is reduced to 20 K. Stability tests of the FEMs, including a measurement of the 1/f knee frequency, also meet mission requirements. The 30 and 44 GHz FEMs have met or bettered the mission requirements in all critical aspects. The most sensitive LNAs have reached new limits of noise temperature for HEMTs at their band centres. The FEMs have well-defined linear polarization characteristcs.

description: The hierarchical organisation of biological systems plays a crucial role in the pattern formation of gene expression resulting from the morphogenetic processes, where autonomous internal dynamics of cells, as well as cell-to-cell interactions through membranes, are responsible for the emergent peculiar structures of the individual phenotype. Being able to reproduce the systems dynamics at different levels of such a hierarchy might be very useful for studying such a complex phenomenon of self-organisation. The idea is to model the phenomenon in terms of a large and dynamic network of compartments, where the interplay between inter-compartment 
and intra-compartment events determines the emergent behaviour resulting in the formation of spatial patterns. 
According to these premises the thesis proposes a review of the different approaches already developed in modelling developmental biology problems, as well as the main models and infrastructures available in literature for modelling biological systems, analysing their capabilities in tackling multi-compartment / multi-level models. 
The thesis then introduces a practical framework, MS-BioNET, for modelling and simulating these scenarios exploiting the potential of multi-level dynamics. This is based on (i) a computational model featuring networks of compartments and an enhanced model of chemical reaction addressing molecule transfer, (ii) a logic-oriented language to ﬂexibly specify complex simulation scenarios, and (iii) a simulation engine based on the many-species/many-channels optimised version of Gillespie’s direct method. 
The thesis ﬁnally proposes the adoption of the agent-based model as an approach capable of capture multi-level dynamics. 
To overcome the problem of parameter tuning in the model, the simulators are supplied with a module for parameter optimisation. The task is deﬁned as an optimisation problem over the parameter space in which the objective function to be minimised is the distance between the output of the simulator and a target one. The problem is tackled with a metaheuristic algorithm. 
As an example of application of the MS-BioNET framework and of the agent-based model, a model of the ﬁrst stages of Drosophila Melanogaster development is realised. The model goal is to generate the early spatial pattern of gap gene expression. The correctness of the models 
is shown comparing the simulation results with real data of gene expression with spatial and temporal resolution, acquired in free on-line sources.

description: The main work involved the PMWS (Post-weaning multisystemic Wasting Syndrome), caused by PCV-2 (Porcine Circovirus type 2) that involved post-weaned pigs. Merial Italy has funded a study activity in which groups of 3-5 animals were sampled for lungs, tracheo-bronchial and superficial inguinal lymph nodes, ileum and tonsils. The protocol applied can be identified as a more diagnostic potential on the individual than on the group.
PNP. Another investigation has been conducted to study proliferative and necrotizing pneumonia (PNP), a form of interstitial pneumonia in weaning and post-weaning pigs characterized by hypertrophy and hyperplasia of type II pneumocytes, coagulative necrosis and granular debris within alveolar spaces. Many studies suggest porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) as the main causes of the disease, but Aujeszky disease virus (ADV) and swine influenza virus (SIV) are also considered. An immunohistochemical study was carried out to evaluate the role of these viruses in PNP lesions in Italy. PNP results primarily associated with PRRSV, even if co-infection is characterized by more severe histological features.
Reproductive pathology. A major risk factor for PCV2 infection is a viraemic episode taking place in pregnant sows with low antibody titer which is transmitted by specific PCV2 products of conception. PCV2 can infect the fetus even by vehicles through infected semen or ova, or as a result of infection of the genital tract. An investigation was carried out to identify the presence and localization of PCV2 in the genital tracts of sows experimentally infected with PCV2 and in their fetuses. The results obtained suggest that: conventional sows can be infected by intrauterine exposition; low antibody titres increase the probability of infection; PCV2 infection close to insemination time reduces the pregnancy rate; placental lesions may represent an additional cause of fetal suffering.

description: We revisit the WMAP dark matter constraints on Yukawa Unification in the presence of massive neutrinos. The large neutrino mixing indicated by the data modifies the predictions for the bottom quark mass, and enables Yukawa also for large $\tanβ$, and for positive $μ$ that were previously disfavoured. As a result, the allowed parameter space for neutralino dark matter also increases, particularly for areas with resonant enhancement of the neutralino relic density.

Formal planning rationality in public sector professional work: between discourse and practice

description: Although rational models of formal planning have been seriously criticized by strategy literature, they not only remain a widely used organizational practice in private firms, but they have increasingly been entering public, professional organizations too, as part of public sector managerial reforms. This research addresses this apparent paradox, exploring the meaning of formal planning in public sector professional work. 
Curiously, this is an issue that remains under-investigated in the literature: the long debate on formal planning in strategy research devoted scant attention to its diffusion in the public sector, and public sector studies have scrutinized the introduction of other management tools in professional work, but very limitedly formal planning itself. In fact, little is known on the actual meaning of formal planning in public, professional services.
This research is based upon a case of adoption of formal planning tools in a public hospital. Embracing a discourse analytical lens, it examines which formal planning discourse entered professional work, to what extent, and how professionals interpret it and engage with it in their practice. 
The analysis uncovers dynamics of social construction of meaning where, eventually, a formal planning discourse both shapes and is shaped by professional practice. In particular, it is found that formal planning rationality largely penetrated professional work, but not to the detriment of professional values. Morevover, formal planning ‘fails’ as a tool for rational decision making, but it takes up a knowledge work and a social value in professional work, as a tool for explicitation of action courses and for dialogue between otherwise more disconnected parts of the organization.
NOVI MAGISTRAT Jože Plečnik, progetti per il centro monumentale di Lubiana

description: This research work analyzes the theme of the architecture of the city and aims at establishing, by studying the urban project of the new town hall in Ljubljana made by the Slovenian architect Jože Plečnik, the idea that the construction of the city must be carried out through a type of architecture directed at the planning of collective urban spaces.

The plan for the new town hall building, drew in three versions – 1932, 1939, and 1940-41 –, is part of a large set of plans concerning the area that Plečnik defines to be the “osrčje” (heart) of Ljubljana, that is, the central area within the castle hill and the distinctive arc of the Ljubljanica River, on the eastern boundary of the old “mesto” (town). Among the Plečnik's projects on urban scale for Ljubljana, the above-mentioned plans, unbuilt and scarcely published, must be considered to be ones of the least known, despite their importance in the professional activity of the architect.

The work consists of three parts: the first part describes the background of theories and projects which shaped Plečnik's urban culture, during the years of his education in Vienna and before the beginning of the planning activities this work focuses on; the second part studies the plans for the “heart” of the city; the third part investigates the plan for the new town hall building by means of the graphical reconstruction of the three plan versions made by Plečnik, and it provides insights into the relationships among form, significance and motivation of his work.

Since the plans have never been built, the digital tridimensional reconstruction of the building models allowed to show unknown spaces and confirm that Architecture has a particular significance when its goal is the planning of collective urban spaces.
The gender wage gap in developing and transition countries

description: The aim of my dissertation is to study the gender wage gap with a specific focus on developing and
transition countries. In the first chapter I present the main existing theories proposed to analyse the
gender wage gap and I review the empirical literature on the gender wage gap in developing and
transition countries and its main findings. Then, I discuss the overall empirical issues related to the
estimation of the gender wage gap and the issues specific to developing and transition countries.
The second chapter is an empirical analysis of the gender wage gap in a developing countries, the
Union of Comoros, using data from the multidimensional household budget survey “Enquete
integrale auprès des ménages” (EIM) run in 2004. The interest of my work is to provide a
benchmark analysis for further studies on the situation of women in the Comorian labour market
and to contribute to the literature on gender wage gap in Africa by making available more
information on the dynamics and mechanism of the gender wage gap, given the limited interest on
the topic in this area of the world. The third chapter is an applied analysis of the gender wage gap in
a transition country, Poland, using data from the Labour Force Survey (LSF) collected for the years
1994 and 2004. I provide a detailed examination of how gender earning differentials have changed
over the period starting from 1994 to a more advanced transition phase in 2004, when market
elements have become much more important in the functioning of the Polish economy than in the
earlier phase. The main contribution of my dissertation is the application of the econometrical
methodology that I describe in the beginning of the second chapter. First, I run a preliminary OLS
and quantile regression analysis to estimate and describe the raw and conditional wage gaps along
the distribution. Second, I estimate quantile regressions separately for males and females, in order
to allow for different rewards to characteristics. Third, I proceed to decompose the raw wage gap
estimated at the mean through the Oaxaca-Blinder (1973) procedure. In the second chapter I run a
two-steps Heckman procedure by estimating a model of participation in the labour market which
shows a significant selection bias for females. Forth, I apply the Machado-Mata (2005) techniques
to extend the decomposition analysis at all points of the distribution. In Poland I can also implement
the Juhn, Murphy and Pierce (1991) decomposition over the period 1994-2004, to account for
effects to the pay gap due to changes in overall wage dispersion beyond Oaxaca’s standard
decomposition.
