description: Understanding the structure and properties of refractory oxides are critical for high temperature applications. In this work, a combined experimental and simulation approach uses an automated closed loop via an active-learner, which is initialized by X-ray and neutron diffraction measurements, and sequentially improves a machine-learning model until the experimentally predetermined phase space is covered. A multi-phase potential is generated for a canonical example of the archetypal refractory oxide, HfO2, by drawing a minimum number of training configurations from room temperature to the liquid state at ~2900oC. The method significantly reduces model development time and human effort.

description: We consider protected operators with the same conformal dimensions in the ultraviolet and infrared fixed point. We derive a sum rule for the difference between the two-point function coefficient of these operators in the ultraviolet and infrared fixed point which depends on the two-point function of the scalar operator. In even dimensional conformal field theories, scalar operators with exactly integer conformal dimensions are associated with Type-B conformal anomalies. The sum rule, in these cases, computes differences between Type-B anomaly coefficients. We argue the positivity of this difference in cases in which the conformal manifold contains weakly coupled theories. The results are tested in free theories as well as in $\mathcal N = 2$ superconformal QCD, necklace quivers and holographic RG flows. We further derive sum rules for currents and stress tensor two-point functions.

description: The preparation of quantum systems and the execution of quantum information tasks between distant users are always affected by gravitational and relativistic effects. In this work, we quantitatively analyze how the curved space-time background of the Earth affects the classical and quantum correlations between photon pairs that are initially prepared in a two-mode squeezed state. More specifically, considering the rotation of the Earth, the space-time around the Earth is described by the Kerr metric. Our results show that these state correlations, which initially increase for a specific range of satellite's orbital altitude, will gradually approach a finite value with increasing height of satellites orbit (when the special relativistic effects become relevant). More importantly, our analysis demonstrates that the changes of correlations generated by the total gravitational frequency shift could reach the level of <0.5$\%$ within the satellites height at geostationary Earth orbits.

Στην εργασία αυτή θα ασχοληθούμε με τρεις μεθόδους γραμμικοποίησης πολυωνυμικών πινάκων, την προσθετική μέθοδο, τη μέθοδο των μεταθέσεων και την πολλαπλασιαστική μέθοδο. Την κάθε μία από αυτές τις μεθόδους συνοδεύουν αρκετά παραδείγματα και ορισμένα σχόλια και παρατηρήσεις. Τέλος, θα ολοκληρώσουμε τη μελέτη μας με την παρουσίαση μιας παραλλαγής της πολλαπλασιαστικής μεθόδου που προτείνουμε.
description: This master thesis discusses the techniques used for linearization polynomial matrices. The aim of linearization is to convert the original polynomial matrix into a larger matrix pencil with the same eigenvalues and eigenvectors. Also, we want to have the same zeros and the same elementary divisors. The most common and convenient method of linearization are the first and second companion forms. The companion forms have plenty advantages. However, a disadvantage haw triggered further research. The inability of companion forms to reflect the structure of the original polynomial matrix led to the development of new methods. These new methods give matrix pencils which will have as many as possible of the advantages that have the companion forms and also they will reflect the structure of the original polynomial matrix. In this thesis we discuss three methods of linearization, the additive method, the permutation method and the multiplication method, each of these will be accompanied by many examples and several comments. Finally, we will complete our study by proposing a variant of the multiplication method.
Effectiveness of stress inoculation training in the treatment of atopic dermatitis
Creators: name: Coles, Nona Diane
Publisher: name: University of British Columbia

description: Research indicates that psychological stress plays a role in aggravating Atopic Dermatitis (AD), a genetically-based, chronic, inflammatory skin disorder. Most psychological interventions used to treat AD have employed behavioural techniques such as relaxation training and biofeedback. Some treatments have focused on reducing individuals' stress level, whereas others have focused on eliminating the scratching behaviour associated with exacerbation of the disorder. Very few studies have used a cognitive behavioural approach to treat AD. Stress Inoculation Training (SIT), a cognitive behavioural stress management program has been successful in treating a wide range of psychosomatic disorders. The purpose of this study, therefore, was to determine the effectiveness of SIT in treating seven women suffering from AD of the hands. A multiple baseline design was employed that included a baseline period of 4 weeks for two of the women and 5 weeks for the other 5 women, followed by 8 weeks of treatment, a 2-week post-intervention period, and a 3-month follow-up. Subjective measures of stress, coping, and extent of AD were repeatedly monitored using a diary technique. In addition, a self-report measure of anxiety and quality of life was administered weekly and objective ratings of skin condition were made on three occasions. The data were analyzed visually and statistically on an individual and group level to determine both they effectiveness of the intervention and the nature of the relationship between AD and aspects of the stress process. Overall, a positive treatment effect was revealed (p<.10), however on an individual basis it was apparent that SIT was effective for 4 of the women and not for 3. Positive relationships were also found between the women's skin condition and aspects of the stress and coping process. Implications for further research are discussed.

description: We review here recent numerical results concerning the acceleration and collimation of relativistic outflows from neutron stars, and we discuss their implications for models of magnetars in their hypothesized initial high rotation states. New results with different injection conditions and extending to much larger distance from the central star are also presented and discussed, showing that, only in the case of weakly magnetized winds, collimated outflows are indeed possible. We finally comment on the possibility that newly born magnetars might trigger GRBs, and we show that numerical results do not support such hypothesis.

description: This paper analyses the practice of signing documents with a series of three crosses, which is attested in Greek and Coptic papyri from the sixth century onwards. According to the usual scheme, the crosses are marked by the term σημεῖον ‘sign’ and the name of the signatory written respectively above and below the signs. A subscription written by a third party usually makes it clear that the signatory, although unable to write, signed the document by drawing his σημεῖον. The paper discusses a) the standard structure and variations of this type of signature, b) its spatial and temporal distribution, c) its origin and development, and d) the context in which it was used.

description: The de-materialization of transactions renders procedural law, and more specifically the law of evidence. The adoption of modern forms of transaction without being supported by flexible procedural law deprives any technological innovation from its practical content. Towards this goal, the Greek procedural legislator has been particularly provident. As early as the introduction of the currently in effect Code of Civil Procedure, in its initial form, an explicit provision was enacted, according to which “mechanical reproductions are considered private documents” (article 444 nr. 3 CCivPr), for which the issuer’s signature in his/her own handwriting (article 443 CCivPr) is required. In addition, the identification of mechanical reproductions with private documents was not legislatively limited only to the level of admissibility of such evidence, but it was also extended to the level of their probative effect. Precisely since private documents constitute full proof concerning that the declaration they contain emanates from the issuer of the document (article 445 CCivPr), in the same way, respectively, mechanical reproductions “constitute full proof of the events or things they represent (article 448 § 2 CCivPr). In both cases, of course, counter proof is allowed. Then, nonetheless, the burden of proof shifts to the side questioning the validity of the document or the mechanical reproduction.

description: Context. Distant galaxy clusters provide an effective laboratory in which to study galaxy evolution in dense environments and at early cosmic times. Aims. We aim to identify distant galaxy clusters as extended X-ray sources coincident with overdensities of characteristically bright galaxies. Methods. We use optical and near-infrared (NIR) data from the Hyper Suprime-Cam (HSC) and VISTA Deep Extragalactic Observations (VIDEO) surveys to identify distant galaxy clusters as overdensities of bright, $z_{phot}\geq 0.8$ galaxies associated with extended X-ray sources detected in the ultimate XMM extragalactic survey (XXL). Results. We identify a sample of 35 candidate clusters at $0.80\leq z\leq 1.93$ from an approximately 4.5 deg$^2$ sky area. This sample includes 15 newly discovered candidate clusters, ten previously detected but unconfirmed clusters, and ten spectroscopically confirmed clusters. Although these clusters host galaxy populations that display a wide variety of quenching levels, they exhibit well-defined relations between quenching, cluster-centric distance, and galaxy luminosity. The brightest cluster galaxies (BCGs) within our sample display colours consistent with a bimodal population composed of an old and red subsample together with a bluer, more diverse subsample. Conclusions. The relation between galaxy masses and quenching seem to be already in place at $z\sim 1$, although there is no significant variation of the quenching fraction with the cluster-centric radius. The BCG bimodality might be explained by the presence of a younger stellar component in some BCGs but additional data are needed to confirm this scenario.

description: Cosmological models involving an interaction between dark matter and dark energy have been proposed in order to solve the so-called coincidence problem. Different forms of coupling have been studied, but there have been claims that observational data seem to narrow (some of) them down to something annoyingly close to the $Λ$CDM model, thus greatly reducing their ability to deal with the problem in the first place. The smallness problem of the initial energy density of dark energy has also been a target of cosmological models in recent years. Making use of a moderately general coupling scheme, this paper aims to unite these different approaches and shed some light as to whether this class of models has any true perspective in suppressing the aforementioned issues that plague our current understanding of the universe, in a quantitative and unambiguous way.

description: Juvenile Delinquency is a complicated social problem and it’ s comprehensive study requires a very extensive analysis. In this diploma thesis, the forms under which this phenomenon is expressed are partially mentioned. This works aims at determining the main reasons, which lead the minors to the adoption of criminal behaviors and also the effective ways for tackling this problem. For analyzing the juvenile delinquency phenomenon, the main factors that can lead young people in delinquency are considered. In the first section, the main theories used for the understanding of juvenile delinquency with an emphasis on sociological theories direction are introduced. Moreover, based on the research data, the factors which cause the onset of delinquent behavior and generally problematical behaviors of minors are analyzed. Finally, social factors such as family, school and social class of the minor are highlighted. In the second part, a short report on the delinquency extend in Greece is initially presented. Furthermore, measures for the prevention and the treatment of juvenile delinquency are registered.

description: A mechanical system consisting of an elastic beam under harmonic excitation and an attached sliding body is investigated. Recent experimental observations suggest that the system passively (self-)adapts the axial location of the slider to achieve and maintain a condition of self-resonance, which could be useful in applications such as energy harvesting. The purpose of this work is to provide a theoretical explanation of this phenomenon based on an appropriate model. A key feature of the proposed model is a small clearance between the slider and the beam. This clearance gives rise to backlash and frictional contact interactions, both of which are found to be essential for the self-adaptive behavior. Contact is modeled in terms of the Coulomb and Signorini laws, together with the Newton impact law. The set-valued character of the contact laws is accounted for in a measure differential inclusion formulation. Numerical integration is carried out using Moreau's time-stepping scheme. The proposed model reproduces qualitatively most experimental observations. However, although the system showed a distinct self-adaptive character, the behavior was found to be non-resonant for the considered set of parameters. Beside estimating the relationship between resonance frequency and slider location, the model permits predicting the operating limits with regard to excitation level and frequency. Finally, some specific dynamical phenomena such as hysteresis effects and transient resonance captures underline the rich dynamical behavior of the system.

Children in childcare homes: a qualitative study to explore their educational experiences in state schools in Goa
Creators: name: Pinto, Tanya
Publisher: name: Anglia Ruskin Research Online (ARRO)
Year: 2024

description: Various research studies have examined the relationship between parenting and schooling. This study explores the educational experiences of children without biological parents, residing in a childcare home and studying in a mainstream state school in the Indian state of Goa.According to Bourdieu’s theory of social reproduction, a conventional school setting and the teaching staff enable social reproduction to take place, such that the children’s educational outcomes and career aspirations tend to align with their parents’ cultural and social capital. Involving the children’s own perspectives, this study explores how in the context of children who are raised in a childcare home setting without their own parents, the children negotiate their academic and extra- curricular experiences in school and beyond. The theoretical framework is based on three interconnected theories: Bourdieu's social reproduction theory (1977), Yosso's (2005) Community Cultural Wealth, and Connell’s (2014) Southern Theory which emphasises the importance of decolonising social thought in theory, research, and application. The exploratory, multiple case study approach was used to interview children across two childcare homes, as well as teachers who taught in schools which children in care attended. Thematic analysis (Boyatzis, 1998) was used to analyse the data, with the findings highlighting how the children’s own agency and their peer relationships help strengthen their own unique capital, helping them navigate their educational experiences.

description: We provide the first classification of three-photon eigenstates in a finite periodic array of two-level atoms coupled to a waveguide. We focus on the strongly subwavelength limit and show the hierarchical structure of the eigenstates in the complex plane. The main characteristic eigenstates are explored using entanglement entropy as a distinguishing feature. We show that the rich interplay of effects from order, chaos to localisation found in two-photon systems extends naturally to three-photon systems. There also exist interaction-induced localised states unique to three-photon systems such as bound trimers, corner states and trimer edge states.

Due codici bobbiesi gemelli, un restauro quattrocentesco: il manoscritto F.IV.8 della Vita Gregorii Magni di Giovanni Immonide nella Biblioteca nazionale universitaria di Torino
Creators: name: Rosso, Chiara
Publisher: name: Scrineum
Year: 2023

description: The paper focuses on the late ninth-century Bobbio manuscript Torino, Biblioteca nazionale universitaria, F.IV.8, witness of Iohannes Hymmonides’ Vita Gregorii Magni, followed by the slightly later-added text of the visio Dryhthelmi, from Bede’s Historia ecclesiastica (V, 12). The codex bears clear traces of a mid-fifteenth-century restoration, aimed at filling lacunae of various entities along the text. The presence of two conspicuous errors, respectively between quires 12 and 13, and quire 16 and f. 124, urges further codicological and paleographical investigation on the codex. From this analysis some clues emerge to the existence of two ʻtwinʼ codices, which were merged together, in order to make one manuscript out of two formerly autonomous, damaged witnesses. Eight fragments once belonging to these two copies of the Vita Gregorii and then reused as guard-leaves in other Bobbio manuscripts now preserved in the Ambrosiana and Vaticana Libraries, as well as in the Turin Library itself, corroborate the hypothesis. It thus appears that, shortly after the publication of the biography of Gregory the Great, the Bobbio scriptorium drawn it up in two copies, the one for the abbey library, the other for the nearby small book collection kept at the Spelunca.

description: Generally the virial theorem provides a relation between various components of energy integrated over a system. This helps us to understand the underlying equilibrium. Based on the virial theorem we can estimate, for example, the maximum allowed magnetic field in a star. Recent studies have proposed the existence of highly magnetized white dwarfs, with masses significantly higher than the Chandrasekhar limit. Surface magnetic fields of such white dwarfs could be more than 10^9 G with the central magnitude several orders higher. These white dwarfs could be significantly smaller in size than their ordinary counterparts (with surface fields restricted to about 10^9 G). In this paper we reformulate the virial theorem for non-rotating, highly magnetized white dwarfs (B-WDs) in which, unlike in previous formulations, the contribution of the magnetic pressure to the magnetohydrostatic balance cannot be neglected. Along with the new equation of magnetohydrostatic equilibrium, we approach the problem by invoking magnetic flux conservation and by varying the internal magnetic field with the matter density as a power law. Either of these choices are supported by previous independent work and neither violates any important physics. They are useful while there is no prior knowledge of field profile within a white dwarf. We then compute the modified gravitational, thermal and magnetic energies and examine how the magnetic pressure influences the properties of such white dwarfs. Based on our results we predict important properties of these B-WDs, which turn out to be independent of our chosen field profiles.

description: Building on an old result of Duncan and Namioka, we show that the ${\ell}^1$-convolution algebra of a semilattice $S$ is biflat precisely when $S$ is uniformly locally finite. The proof shows in passing that for such $S$ the convolution algebra is isomorphic to ${\ell}^1(S)$ with pointwise multiplication. At the end we sketch how these techniques may be extended to prove an analogous characterisation of biflatness for Clifford semigroup algebras.

Scrivere tra due mondi: la digrafia e la comunità francese a Roma nel XVI secolo
Creators: name: D'Uonno, Federica
Publisher: name: Scrineum Rivista
Year: 2023

description: This paper explores digraphia – the ability for one person to use two different scripts at the same time – in the 16th-century French community in Rome, where both cancelleresca italica and modern French cursive coexisted. It aims to verify what influenced French writers to adopt distinct graphic solutions, based on their relationship with the text, language, and function of writing. The phenomenon is mostly represented by professional writers, who were able to master both graphic styles at the same level of expertise. Nevertheless, there are also some writers who employ both scriptures at an usual level, showing a higher degree of contamination. All these writers – particularly when acting as delegated writers – show great awareness in their choice of one graphic style over the other.

La ricezione della normativa edittale nelle carte longobarde dell’Italia settentrionale. Prospettive e casi di studio
Creators: name: Feletti, Federico
Publisher: name: Scrineum
Year: 2023

description: Historians have recently and fruitfully resumed work on early medieval laws. As regards the problem of the reception of post-roman normative collections in contemporary legal practice, Italian documentation offers a rich working field that allows for a comparison between the charters and the laws. On the basis of this material, it is possible to evaluate the spread, and primary characteristics, of legal expertise in Lombard Italy. Northern Italic charters show strict bonds with Lombard laws. The effects of the royal edicts can be observed in the procedure of the legal acts and are sometimes recognizable in the wording of the charters as well. These laws are often referred to and, in some cases, openly quoted. A group of charters involving purchases of women’s mundium and two charters settling disputes regarding usurpations of lands and accompanying violence reveal flexible uses of the laws, which in any case appear to be well known to the authors of the documents. The possibility to deviate from the law was indeed granted by a provision of king Liuthprand (chapter 91 of his laws). On the other hand, two judgment records show the lex scripta at the core of the procedure of the public hearing.

Report on Welfare in Italy.
Trying to Answer some Questions
which Arise from the Present Condition of Welfare in Italy
Creators: name: D'Angelosante, Melania
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2015
Subjects: IUS/10 Diritto amministrativo

description: The main aim of the report is to give a general picture of the present condition of welfare in Italy, also extended to its relationship with the economic recession.
However, he analysis is focused on several sectors, even though really important, which are health, social assistance, social housing. It is also focused on specific cases regarding some policies in the field of education, work and social security (i.e. aid for students with disabilities and family benefits). This choice is due primarily to the will to leave out of the study most of the education and work sector (including social security, strictly related to the work policies), which are generally regulated and managed on the basis of their own particular needs.
The final goal of the report is to try to answer the following questions arising from the existing legal framework: 
-	is there a general trend to reduce social welfare entitlements? If so, is such a trend conditioned, to any extent, by ex ante planning (policies) or it is only driven by emergency reasons? What is the role played by fiscal federalism and the constitutional reform regarding the budget balance?
-	Are public authorities reducing their participation in granting social services and rights?
-	What is the relationship between the above mentioned trend and the economic recession? Did such a trend start before the financial crisis?
-	What are the role and limits of the administrative discretion in distributing benefits and/or services with the aim of granting social rights? What is the relationship between this discretion and the bureaucratic rules in the implementation of the welfare policies? Are the two models opposed to each other? What is, if existing, the extent and quality of citizens participation in the administrative decision-making process about their entitlements? Can the above mentioned models and participation affect the approach of the courts when considering the challengers of rights bearers?
-	Why in Italy is there not a general Welfare Agenda such as that existing in the UK?
Cartularium Langobardicum

description: The collection of legal “formulas” commonly called Cartularium Langobardicum, rightly defined by Giovanna Nicolaj as “summula teorica e scolastica sulle obbligazioni”, lacks an in-depth study. One of the reasons for the Cartularium’s existence is to indicate the procedure to be followed, in the regime of personality of the laws, by the person conducting the dialogue between the parties involved. The formulas are not immediately intended to provide a frame of reference for the drafting of acts. Rather, it is a dialogical vademecum of the lines and gestures accompanying the course of legal actions: on the one hand, everyday contracts; on the other hand, matters that involve going before the count and before judges. The sources of the compilation, with the exception of Form. 16 concerning the remarriage of the widow under Salic law, are to be found less in the laws or forms of the north of the Alps than in the documents of contemporary practice. An examination of the latter confirms the dating to the Ottonian period already proposed, and more precisely the quarter of a century that separates the end of the 960s from the beginning of the 990s: the Cartularium cannot be linked to the notarial practices in force in the 9th century and is part of a resolutely Italian context. Finally, the identification of some variants between the manuscripts allows for additional observations on its composition and on the adjustments made to the text by the copyists.

description: Teachers in conflict and protracted crisis settings play an essential role in supporting children and young people’s development, yet they face critical challenges concerning teacher management, including recruitment, deployment, professional development, compensation, and career progression. These barriers affect teaching quality and learning outcomes, highlighting an urgent need for comprehensive, data-driven policies that are adaptable to the unique context of these environments.This policy brief summarises actionable findings from the ERICC Evidence Review: Teacher Management in Conflict and Protracted Crisis – the State of the Evidence (forthcoming), which documents persistent challenges and promising practices as well as highlights evidence gaps and research needs. The findings may be useful for governments, donor organisations, humanitarian and development actors, and research bodies working with teachers.The review recommends a multifaceted approach to improving teacher management that is assets-based, to recognise teachers’ inherent knowledge and skills, and prioritise their perspectives and experiences in policymaking. To do so, effective teacher management should include:1. Flexible and responsive policies to recruit, deploy, and train enough teachers across various profiles, and provide meaningful career progression opportunities;2. Equitable compensation and benefits that reflect teachers' contributions as well as market prices, harmonised among education stakeholders; and3. Data-driven policymaking that prioritises teacher participation to value teachers' voices and experiences/expertise in policymaking spaces in ways that strengthen teacher status and professionalisation.Improving teacher management also requires integrating displaced teachers into the workforce, advancing gender equity in recruitment and support for women educators, and enhancing coordination among education stakeholders to ensure equitable employment of teachers of diverse profiles. Targeted funding should also be directed towards training teachers on pedagogies relevant for conflict and crisis-settings and that culminate in recognised qualifications and establishing stable salary mechanisms to support educators across varied profiles and settings.These recommendations aim to improve the overall quality of education by fostering a more inclusive and effective educational environment that is responsive to the needs of conflict-affected communities.

description: A general class of cosmological models driven by a non-local scalar field inspired by string field theories is studied. In particular cases the scalar field is a string dilaton or a string tachyon. A distinguished feature of these models is a crossing of the phantom divide. We reveal the nature of this phenomena showing that it is caused by an equivalence of the initial non-local model to a model with an infinite number of local fields some of which are ghosts. Deformations of the model that admit exact solutions are constructed. These deformations contain locking potentials that stabilize solutions. Bouncing and accelerating solutions are presented.

Specializzazioni grafiche e forme della documentazione nelle Alpi occidentali (Savoia, Borgogna transgiurana, secoli XII-XIII)
Creators: name: Buffo, Paolo
Publisher: name: Scrineum

description: The essay focuses on the relationship between the emergence of new agents and forms of documentation and the transformations of documentary handwriting in the western Alps between the 12th and 13th centuries, in the context of the European genesis of new cursive graphic languages. Firstly, the chancelleries that produced documents for private individuals in Sion, Aosta and Saint-Maurice are analysed: in the first two cases, the use of distinctive graphic styles contributed to fixing the extrinsic characteristics of the documentary types which were associated with those offices. The graphic behaviour of the notaries working as officers of the counts of Savoy is then analysed. Throughout most of the 13th century, they used rapid scripts but not properly cursive graphic chains; the latter were introduced during the second half of the century, in the new documentary types these notaries constructed for the administrative management of princely domains. In all the contexts examined by the essay, the use of cursivity or the textualis model coexisted as possible choices, between which many scribes could oscillate with individual digraphical outcomes.

Emergent rhythms in coupled nonlinear oscillators due to dynamic interactions

description: The role of a new form of dynamic interaction is explored in a network of generic identical oscillators. The proposed design of dynamic coupling facilitates the onset of a plethora of asymptotic states including synchronous states, amplitude death states, oscillation death states, a mixed state (complete synchronized cluster and small amplitude unsynchronized domain), and bistable states (coexistence of two attractors). The dynamical transitions from the oscillatory to death state are characterized using an average temporal interaction approximation, which agrees with the numerical results in temporal interaction. A first-order phase transition behavior may change into a second-order transition in spatial dynamic interaction solely depending on the choice of initial conditions in the bistable regime. However, this possible abrupt first-order like transition is completely non-existent in the case of temporal dynamic interaction. Besides the study on periodic Stuart-Landau systems, we present results for paradigmatic chaotic model of Rössler oscillators and Mac-arthur ecological model.

description: Στην παρούσα διπλωματική εργασία αναλύεται η εξαγωγική δυναμικότητα της Ιταλίας μέσα από τις επιδράσεις της βιομηχανικής πολιτικής, λαμβάνοντας υπόψη τρεις βασικές θεωρίες του διεθνούς εμπορίου. Βασικό κομμάτι του εγχειρήματος λαμβάνει η ανάλυση της έννοιας της βιομηχανικής πολιτικής, τόσο σε θεωρητικό όσο και σε πρακτικό επίπεδο με τη θεσμοθέτηση συγκεκριμένων μέτρων από πλευράς του κράτους της υπό εξέταση χώρας, της Ιταλίας. Πιο συγκεκριμένα, μεταβλητές όπως η παραγωγικότητα της εργασίας, το μισθολογικό κόστος και οι δαπάνες για Ε&Α, οι οποίες αντιπροσωπεύουν καθεμία, μία από τις βασικές θεωρίες διεθνούς εμπορίου των Ricardo, Heckscher- Ohlin και Posner αντίστοιχα και στις οποίες αναφέρονται τα μέτρα βιομηχανικής πολιτικής, επηρεάζουν την εξωστρέφειά της οικονομίας σε όρους εμπορικής συναλλαγής. Εν προκειμένω, η ανάλυση γίνεται για 24 βιομηχανικούς κλάδους της ιταλικής οικονομίας, με στοιχεία από τις βάσεις δεδομένων της Eurostat και της UN Comtrade για το έτος 2008, χρησιμοποιώντας τη μέθοδο OLS. Τα αποτελέσματα δεν έδειξαν να επαληθεύουν σε όλες τις περιπτώσεις τη θεωρία πως οι προαναφερόμενες μεταβλητές επηρεάζουν θετικά τις εξαγωγές. Ειδικότερα, η παραγωγικότητα της εργασίας αποδεικνύεται στατιστικά ασήμαντη, ενώ οι άλλες δύο κρίνονται σημαντικές στην ερμηνεία των ιταλικών εξαγωγών. Ωστόσο, μόνο το πρόσημο του μισθολογικού κόστους είναι θετικό και συμβατό με προηγούμενες μελέτες, εν αντιθέσει με τις δαπάνες για Ε&Α που έχουν αρνητικό πρόσημο.
description: The present paper examines Italy’s export capability through the influence of industrial policy and taking into account the three basic theories of international trade. Of course, one of the most important parts of this paper refers to theory of industrial policy and to the practical measures that Italian government legislates. More precisely, variables like labor productivity, wages and R&D expenses, that represent the theories of Ricardo, Heckscher- Ohlin and Posner respectively and are referring to the measures of industrial policy, affect Italy’s exports. Moreover, at present the analysis is based on data for 24 industrial branches of Italy’s economy for the year 2008, derived from the Eurostat and the UN Comtrade databases. The method is the OLS method. The results of our analysis are not generally supportive of all the initial hypotheses on the positive influence of the above theories on the exports. We found that labor productivity is not statistical significant, but wages and R&D expenses are. However, only the sign of wages is positive and accords to the theory. On the contrary R&D expenses have a negative effect on Italy’s exports.
