description: Demographic trends suggest increasing numbers of multiple racial heritage students attending US campuses and universities, a change reflected within psychology.  However, there is little empirical investigation into the educational needs of multiracials.  The current project addressed this gap by utilizing quantitative survey and qualitative interview data from a recently conducted national study to explore the perceptions of multiracial undergraduate and graduate students within psychology.  The focus of the current study was the comparison of Asian American/European American and Latino/a/European American multiracial students to their single heritage counterparts on several variables of interest - academic supports and barriers; linkage between barriers faced and ethnicity; perceived cultural diversity; and perceptions of the extent of cultural diversity related to satisfaction.  Furthermore, exploratory differences in these variables related to multiracial self-identification and the variables of satisfaction, specialness and representation in psychology were examined.  Both multiracial groups reported more of a link between academic barriers experienced and their ethnicity than European American students, but less of a link than their monoracial minority peers.  Also, both multiracial groups were more likely to report that their ethnic group was not represented in psychology than fairly represented, compared to European American peers, but less likely to report this compared to their monoracial minority counterparts.  The same pattern of findings existed for student's perceptions that psychology had something special to offer their ethnic group.  In other cases, differences were not found between the multiracial groups and their monoracial counterparts, or between the two multiracial groups.

Antisocial Personality Disorder and Romantic Relationship Functioning  in an Epidemiologically-Based Sample

description: The objective of this project was to characterize the romantic relationship functioning of those with Antisocial Personality Disorder (ASPD). There is a gap in the literature on this topic. An epidemiologically-based, longitudinal, community sample collected by researchers at the Johns Hopkins Bloomberg School of Public Health (N = 1297) was used. It was hypothesized that the relationship functioning of participants with ASPD would be more maladaptive as compared to those without ASPD. This notion was generally supported. Relationships of those with ASPD were found to be more impaired regarding: general relationship quality, confiding with their partners, sharing activities with their partners, communication, number of partnerships (i.e., promiscuity), mutual emotional abuse, and mutual physical abuse. However, affection, commitment, and viewing their relationships as important were not found to differ between the ASPD and non-ASPD groups. Unexpectedly, relationships of those with ASPD were found to be longer than those without ASPD.  A gender interaction was found for emotional and physical abuse, but not for relationship quality. There is some evidence, then, that the relationships of women are particularly impacted by ASPD. Counter to hypotheses, childhood disruptive experiences and maltreatment did not predict adult relationship quality for those with the disorder. However, childhood maltreatment did predict adult relationship quality for those without ASPD.  The goal of establishing heterogeneity regarding romantic relationships within the disorder was thus not met. This study provides empirical evidence of the romantic relationship impairment of those with ASPD and has implications for understanding the relationship strategies these individuals may employ.

Asynchronous hopping and code diversity in frequency hopped code division multiple access systems
Creators: name: Ong, Chong Tean
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is about Frequency Hopped-Code Division Multiple Access (FH-CDMA) systems. More specifically, it studies the packet error rates and system performance of FHCDMA systems with guard times. In the past, a number of simplifying assumptions have been made in the studies of these systems. This work investigates the effects of these simplifying assumptions by deriving exact expressions, which do not make these assumptions, and comparing the results using both methods. By considering edge effects due to the inclusion of guard times, it is shown that the probability of codeword error can be significantly lower. Furthermore, it is found that the independence assumption, where frequency hits within a packet is assumed are independent, leads to larger probability of codeword error. On the other hand, system performance measures such as normalized maximum local traffic and throughput are not significantly altered by these simplifying assumptions. In addition, this work also proposed a new diversity scheme in FH-CDMA systems, which we refer to as code diversity. In such a diversity scheme, the transmitters are allowed to transmit in more than one frequency bin simultaneously. A variety of decoding schemes, including some with optimal bit error rate (BER) performance, for the code diversity system are proposed and studied. It is shown that the code diversity scheme can have a lower BER than conventional FH-CDMA systems and that such a method of transmitting can be used to establish priority classes among the users in the system. It is further shown that error control coding can be included in the code diversity transmission scheme to further improve the BER performance. The performance of several code diversity schemes is studied in a Rayleigh fading and additive white Gaussian noise environment. From the analysis of the various schemes it is found that code diversity can improve the BER.

description: Eine hohe Produktivität leistet einen wesentlichen Beitrag zur Sicherung des Erfolgs von Unternehmen. Ein systematisches Management der Produktivität ist daher ein Erfolgsfaktor für die Unternehmensentwicklung. Dabei sind vielfältige Einflussfaktoren zu berücksichtigen. Im Rahmen einer bundesweiten Befragungsstudie von Fach- und Führungskräften aus Unternehmen der Metall- und Elektroindustrie wurden die drei Faktoren (1) Führung, (2) Strategie und (3) Organisationskultur hinsichtlich ihrer Wirkung auf das Produktivitäts­management bzw. die Produktivität untersucht. Die Ergebnisse zeigen, dass sich eine gute Feedbackkultur sowie kleine Führungsspannen besonders förderlich auf die Produktivität auswirken. Zudem gaben die Befragungsteilnehmer an, dass eine klar formulierte und kommunizierte Mission, Vision und Ziele sowie die Umsetzung einer entsprechenden Strategie förderlich auf die Produktivität wirken. Fraglich ist bisher, wie diese Einflussfaktoren im Rahmen der digitalen Transformation gestaltet werden können, um gleichermaßen ein gesundes Arbeiten 4.0 und eine Steigerung der Produktivität zu erreichen. Hierzu werden im vorliegenden Beitrag Handlungsempfehlungen für kleine und mittelständische Unternehmen vorgestellt.

description: The primary aims of the present study were twofold: First, to examine the  extent to which anger- related cognitions and anger arousal during the Articulated  Thoughts During Simulated Situations ( ATSS) cognitive assessment were associated  with psychological and physical abuse in a sample of court- mandated partner- violent  men before treatment; and second, to examine the extent to which anger- related  cognitions and anger arousal predicted treatment process and adherence variables in a  sub- sample of these individuals. Results indicate that irrational beliefs had significant  and positive relations with psychological and physical abuse at pretreatment.  Furthermore, higher anger- reactivity, defined as the change in state anger from pre to  post ATSS procedure, predicted lower treatment adherence as measured by  homework compliance and treatment attendance. Results also indicated that higher  anger- reactivity significantly predicted lower early therapist ratings of the working  alliance. Implications for research and clinical practice are discussed.

description: The Dirichlet Laplacian in curved tubes of arbitrary constant cross-section rotating together with the Tang frame along a bounded curve in Euclidean spaces of arbitrary dimension is investigated in the limit when the volume of the cross-section diminishes. We show that spectral properties of the Laplacian are, in this limit, approximated well by those of the sum of the Dirichlet Laplacian in the cross-section and a one-dimensional Schrodinger operator whose potential is expressed solely in terms of the first curvature of the reference curve. In particular, we establish the convergence of eigenvalues, the uniform convergence of eigenfunctions and locate the nodal set of the Dirichlet Laplacian in the tube near nodal points of the one-dimensional Schrodinger operator. As a consequence, we prove the "nodal-line conjecture" for a class of non-convex and possibly multiply connected domains. The results are based on a perturbation theory developed for Schrodinger-type operators in a straight tube of diminishing cross-section.

description: Imaging exo-Earths is an exciting but challenging task because of the 10^-10 contrast ratio between these planets and their host star at separations narrower than 100 mas. Large segmented aperture space telescopes enable the sensitivity needed to observe a large number of planets. Combined with coronagraphs with wavefront control, they present a promising avenue to generate a high-contrast region in the image of an observed star. Another key aspect is the required stability in telescope pointing, focusing, and co-phasing of the segments of the telescope primary mirror for long-exposure observations of rocky planets for several hours to a few days. These wavefront errors should be stable down to a few tens of picometers RMS, requiring a permanent active correction of these errors during the observing sequence. To calibrate these pointing errors and other critical low-order aberrations, we propose a wavefront sensing path based on Zernike phase-contrast methods to analyze the starlight that is filtered out by the coronagraph at the telescope focus. In this work we present the analytical retrieval of the incoming low order aberrations in the starlight beam that is filtered out by an Apodized Pupil Lyot Coronagraph, one of the leading coronagraph types for starlight suppression. We implement this approach numerically for the active control of these aberrations and present an application with our first experimental results on the High-contrast imager for Complex Aperture Telescopes (HiCAT) testbed, the STScI testbed for Earth-twin observations with future large space observatories, such as LUVOIR and HabEx, two NASA flagship mission concepts.

description: Hintergrund: Aus Fachliteratur und empirischer Forschung geht hervor, dass Altersbilder einen wichtigen Einfluss auf die Gesundheit einer Person nehmen. In Anbetracht des demografischen Wandels rückt das „gesunde Altern“ in den Fokus der Wissenschaft, welches insbesondere schon in jungen Jahren angestrebt werden sollte. Der Beitrag soll einen Einblick in die Pilotstudie liefern, welche untersucht hat, ob durch das Tragen eines Modularen Alterssimulationsanzugs Einfluss auf Altersbilder junger Erwachsener genommen werden kann.


Methode: Im Rahmen der Pilotstudie wurde die Studienpopulation (Alter zwischen 18 und 30 Jahren) in zwei Gruppen aufgeteilt: Kontroll- und Interventionsgruppe. Mittels identischer Online-Fragebögen wurde zu verschiedenen Messzeitpunkten untersucht, ob durch eine Intervention im Sinne des „Instant Aging“ das Altersbild beeinflusst wird. Die Probanden absolvierten hierbei einen standardisierten und an alltäglichen Aufgaben orientierten Versuchsablauf im Alterssimulationsanzug.


Ergebnisse: In der Interventionsgruppe zeichnet sich ein direkter Einfluss durch die Intervention ab. Ein Langzeiteffekt konnte aufgrund nicht signifikanter Ergebnisse nicht belegt werden. Folglich können keine konkreten Schlussfolgerungen getroffen werden.


Folgerung: Die Ergebnisse in der Pilotstudie lassen zwar einen Langzeiteffekt vermuten, um allerdings ableitbare und signifikante Ergebnisse zu erhalten, besteht weiterer Forschungsbedarf.

description: Coupled oscillators are among the simplest composite quantum systems in which the interplay of entanglement and interaction may be explored. We examine the effects of coupling on fluctuations of the coordinates and momenta of the oscillators in a single-excitation entangled state. We discover that coupling acts as a mechanism for noise transfer between one pair of coordinate and momentum and another. Through this noise transfer mechanism, the uncertainty product is lowered, on average, relatively to its non-coupled level for one pair of coordinate and momentum and it is enhanced for the other pair. This novel mechanism may be explored in precision measurements in entanglement-assisted sensing and metrology.

description: The paper is an inquiry of the algebraic foundations of the theory of dispersionless integrable hierarchies, like the dispersionless KP and modified KP hierarchies and the universal Whitham's hierarchy of genus zero. It stands out for the idea of interpreting these hierarchies as equations of coisotropic deformations for the structure constants of certain associative algebras. It discusses the link between the structure constants and the Hirota's tau function, and shows that the dispersionless Hirota's bilinear equations are, within this approach, a way of writing the associativity conditions for the structure constants in terms of the tau function. It also suggests a simple interpretation of the algebro-geometric construction of the universal Whitham's equations of genus zero due to Krichever.

description: Detector blinding attacks have been proposed in the last few years, and they could potentially threaten the security of QKD systems. Even though no complete QKD system has been hacked yet, it is nevertheless important to consider countermeasures to avoid information leakage. In this paper, we present a new countermeasure against these kind of attacks based on the use of multi-pixel detectors. We show that with this method, we are able to estimate an upper bound on the information an eavesdropper could have on the key exchanged. Finally, we test a multi-pixel detector based on SNSPDs to show it can fulfill all the requirement for our countermeasure to be effective.

description: Parents of children with autism sometimes experiment with controversial treatments in the hopes of ameliorating their children's autistic characteristics. When parents do seek training on empirically-based treatments, training programs are typically held outside the home. Some parents are unable to access to traditional parent training programs because of cost, transportation, and child-care issues associated with these training programs. The purpose of this study was to explore the effectiveness of an online training program to teach empirically-based interventions to parents of children with autism in the home environment. The online program was designed to teach parents skills to decrease problem behaviors exhibited by their children with autism. The intervention package provided training on priming techniques, extinction, differential reinforcement, visual supports, and systematic instruction to reduce problem behavior. Three parents of children with autism participated in this study. The participants implemented the strategies learned from the training website with the support of web-based consultations from the investigator. A nonconcurrent multiple baseline design across participants indicated the parents learned to correctly implement the behavioral intervention in the home environment. In addition, the children exhibited substantial decreases in disruptive behavior when the parents consistently implemented the intervention components. These results suggest online training programs may provide useful and cost efficient alternatives to traditional parent-training programs.

description: In the present paper, two existing nonlinear system identification methodologies are used to identify data-driven models. The first methodology focuses on identifying the system using steady-state excitations. To accomplish this, a phase-locked loop controller is implemented to acquire periodic oscillations near resonance and construct a nonlinear-mode model. This model is based on amplitude-dependent modal properties, i.e. does not require nonlinear basis functions. The second methodology exploits uncontrolled experiments with broadband random inputs to build polynomial nonlinear state-space models using advanced system identification tools. The methods are applied to two experimental test rigs, a magnetic cantilever beam and a free-free beam with a lap joint. The respective models of both methods and both specimens are then challenged to predict dynamic, near-resonant behavior observed under different sine and sine-sweep excitations. The vibration prediction of the nonlinear-mode and state-space models clearly highlight the capabilities and limitations of the models. The nonlinear-mode model, by design, yields a perfect match at resonance peaks and high accuracy in close vicinity. However, it is limited to well-spaced modes and sinusoidal excitation. The state-space model covers a wider dynamic range, including transient excitations. However, the real-life nonlinearities considered in this study can only be approximated by polynomial basis functions. Consequently, the identified state-space models are found to be highly input-dependent, in particular for sinusoidal excitations where they are found to lead to a low predictive capability.

description: Als Werkzeuge der virtuellen Ergonomie dienen arbeitswissenschaftliche digitale Menschmodelle zur ergonomischen Gestaltung von Produkten und Arbeitsplätzen. Einen hohen Bedarf für die Weiterentwicklung sehen Anwender vor allem in der Integration von Kraftanalysen. Eine Möglichkeit zur gelenkwinkel- und kraftrichtungsabhängigen Berechnung statischer Aktionskräfte basiert auf Gelenkmomenten, welche in Maximalmomentkörpern modelliert werden. Auf eine komplexe Muskelmodellierung kann dadurch verzichtet werden.


Der Beitrag beschreibt einen standardisierten technischen Aufbau und Workflow zur Berechnung von maximalen Gelenkmomenten menschlicher Bewegungen. Die definierten Haltungen eines Probanden werden mit einem Motion-Capture-System und die Maximalkräfte mit 3D-Kraftmessplatten aufgezeichnet. Im Anschluss werden die kombinierten Messdaten auf das Menschmodell übertragen und die Gelenkmomente berechnet. Dieser Aufbau wird dann an einem praktischen Beispiel angewandt und validiert.


Anhand von drei Gelenkstellungen der Schulter werden mit je 72 Messungen in 26 Richtungen Aktionskräfte aufgebracht. Die daraus resultierenden Gelenkmomente werden in Maximalmomentkörper überführt. Dabei wird untersucht, inwieweit sich die Form der Momentkörper ändert und welche geometrische Modellierung diese Form am Besten wiederspiegelt.

description: Triatomic molecule RaOH combines the advantages of laser-coolability and the spectrum with close opposite-parity doublets. This makes it a promising candidate for experimental study of the $\mathcal{P}$,$\mathcal{T}$-violation. Previous studies concentrated on the calculations for different geometries without the averaging over the rovibrational wave function and stressed the possibility that the dependence of the $\mathcal{P}$, $\mathcal{T}$ parameters on the bond angle may significantly alter the observed value. We obtain the rovibrational wave functions of RaOH in the ground electronic state and excited vibrational state using the close-coupled equations derived from the adiabatic Hamiltonian. The potential surface is constructed based on the two-component relativistic CCSD(T) computation employing the generalized relativistic effective core potential (GRECP) for the Radium atom. The averaged values of the parameters $E_{\rm eff}$ and $E_s$ describing the sensitivity of the system to the electron electric dipole moment and the scalar-pseudoscalar nucleon-electron interaction are calculated and the value of $l$-doubling is obtained.

description: The multi analytical study of terrestrial analogues is a useful strategy to deepen the knowledge about the geological and environmental evolution of Mars and other extraterrestrial bodies. In spite of the increasing importance that LIBS, NIR and Raman techniques are acquiring in the field of space exploration, there is a lack web-based platform providing free access to a wide multi-spectral database of terrestrial analogue materials. The Planetary Terrestrial Analogue Library (PTAL) project aims at responding to this critical need by developing and providing free web accessibility to LIBS, NIR and Raman data from more than 94 terrestrial analogues selected according to their congruence with Martian geological contexts. In this framework, the present manuscript provides the scientific community with a complete overview of the over 4500 Raman spectra collected to feed the PTAL database. Raman data, obtained through the complementary use of laboratory and spacecraft-simulator systems, confirmed the effectiveness of this spectroscopic technique for the detection of major and minor mineralogical phases of the samples, the latter being of critical importance for the recognition of geological processes that could have occurred on Mars and other planets. In light of the forthcoming missions to Mars, the results obtained through the RLS ExoMars Simulator offer a valuable insight on the scientific outcome that could derive from the RLS spectrometer that will soon land on Mars as part of the ExoMars rover payload.
Self-Adaptive Amplified Spontaneous Emission Suppression with a Photorefractive Two-Beam Coupling Filter

description: Amplified spontaneous emission is a source of broadband noise that parasitically limits the achievable gain in laser amplifiers. While optical bandpass filtering elements can suppress these broadband noise contributions, such filters are typically designed around specific frequencies or require manual tuning, rendering them less compatible with tunable laser systems. Here, we introduce a nonlinear self-adaptive filter and demonstrate the suppression of amplified spontaneous emission surrounding the lasing mode of a tunable 780 nm external cavity diode laser, using the two-beam coupling interaction in photorefractive BaTiO$_3$. A peak suppression of $-$10 dB is observed $\pm$2.5 nm from the lasing mode, with an overall 50% filter power throughput. The dynamic photorefractive filter is automatically centered on the peak frequency due to the continuous writing and readout of the volume holographic grating and can thereby also automatically adapt to frequency tuning, drift, or mode hopping with an estimated auto-tuning rate of 100 GHz/s under typical conditions. Additionally, we present opportunities for enhancing filter suppression characteristics via the input intensity ratio and tuning the bandwidth via the coupling angle, toward versatile, self-adaptive optical filtering.

Architectures and Algorithms for Resource Management in Virtualized Cloud Data Centers

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2015

description: Cloud Computing has raised a great interest over the last years as it represents an enabling technology for flexible and ubiquitous access over the network to a set of shared computing resources. Cloud paradigm leverages the instruments of the virtualization technique, such as the \textit{VM Live Migration}, which can be exploited in order to achieve multiple objectives. For instance, it could be used for hardware maintenance purposes or to avoid over-load and under-load in the resources utilization. Another typical use of the VM migration is the consolidation of the workload into a smaller number of physical hosts: this is one of the techniques aimed at increasing the energy efficiency of the IT infrastructure, which represents the motivation behind the birth of the \textit{Green Computing}. However, despite all the advantages that come from the application of the cloud paradigm, there is some reluctance in its adoption for mission critical infrastructures because of the security pitfalls it still exhibits, as well as the lack of mechanisms intended at increasing isolation and protection from internal and external threats. This thesis is intended at exploring both the described aspects: on one hand, an architecture for enhancing security of a virtualized critical infrastructure is designed and provided with a mitigation strategy based on the Software Defined Networking approach and live migration. On the other hand, migrations are used to propose two VM consolidation strategies with the objective of minimizing the overall infrastructure power consumption.

description: Objective of this thesis is the mapping and structural analysis of the H2 quadrangle, "Victoria", and a reconnaissance study of the geometry and kinematics of lobate scarps on Mercury. To this end, I produced a 1:3,000,000 geologic map of the area using the images provided by the NASA spacecraft MESSENGER, which has been orbiting the planet since March 2011. The structural analysis was supplemented by an innovative method to calculate fault slip data using craters cross-cut by lobate scarps. This method permits to fully constrain remotely-sensed fault kinematics, and it was applied on 16 craters found across 30% of Mercury covered by stereo-DTM data. Inversion of fault slip data gathered within the quadrangle thus allowed the estimation of the orientation of the stress field pertaining to the mapped lobate scarp systems.

description: We study the effect of combining spin fluctuations and forward scattering electron-phonon ({\eph}) coupling on the superconductivity in the FeSe/SrTiO$_3$ system modeled by a phenomenological two-band Hubbard model with long-range {\eph} interactions. We treat the electron and phonon degrees of freedom on an equal footing using a \emph{fully} self-consistent FLEX plus Migdal-Eliashberg calculation, which includes a self-consistent determination of the spin fluctuation spectrum. Based on FeSe monolayers, we focus on the case where one of the bands lies below the Fermi level (i.e. incipient), and demonstrate that the combined interactions can enhance or suppress $T_c$, depending on their relative strength. For a suitable choice of parameters, the spin-fluctuation mechanism yields a $T_c \approx 46.8$ K incipient $s_\pm$ superconductor, consistent with surface-doped FeSe thin films. A forward-focused {\eph} interaction further enhances the $T_c$, as observed in monolayer FeSe on SrTiO$_3$.

A Pulsational Model for the Orthogonal Polarization Modes in Radio Pulsars
Creators: name: Clemens, J. Christopher
name: Rosen, R.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In an earlier paper, we introduced a model for pulsars in which non-radial oscillations of high spherical degree (\el) aligned to the magnetic axis of a spinning neutron star were able to reproduce subpulses like those observed in single-pulse measurements of pulsar intensity. The model did not address polarization, which is an integral part of pulsar emission. Observations show that many pulsars emit radio waves that appear to be the superposition of two linearly polarized emission modes with orthogonal polarization angles. In this paper, we extend our model to incorporate linear polarization. As before, we propose that pulsational displacements of stellar material modulate the pulsar emission, but now we apply this modulation to a linearly-polarized mode of emission, as might be produced by curvature radiation. We further introduce a second polarization mode, orthogonal to the first, that is modulated by pulsational velocities. We combine these modes in superposition to model the observed Stokes parameters in radio pulsars.

description: Results of astrometric and BVRI photometric observations of the active asteroid (596) Scheila are presented. The observations were carried out at the Zeiss 1000 telescope of the Sanglokh International Astro-nomical Observatory of the Institute of Astrophysics of the Academy of Sciences of the Republic of Tajikistan on June 16 and 17 and from July 30 to August 1, 2017. The coordinates of the object and its orbit were determined; and the apparent brightness in four filters, the absolute brightness in the V and R filters, and the color indices were obtained. The light curves suggest that no substantial changes in the brightness of asteroid occurred during the observations. The absolute brightness of the asteroid in the V and R filters was 9.1 mag and 8.8 mag, respectively. The mean value of the asteroid diameter was 119 km. The mean values of the color indices B-V=0.72 mag, V-R=0.29 mag, and R-I=0.31 mag agree well with the values for asteroids of the P and D types and its averages. The rotation period of the asteroid estimated from photometric observations was 16.1 h. The analysis of the data has shown that the asteroid continues to exhibit the same values of absolute brightness and other characteristics as those before the collision with a small body in December 2010, though the latter resulted in the outburst event and cometary activity of the asteroid. Most likely, the collision of asteroid (596) Scheila with a small body did not lead to catastrophic changes in the surface of the asteroid or to its compete breakup.

Spazi della Diaeta Mediterranea. Comunicazione del patrimonio intangibile per la valorizzazione del territorio.

description: Diaeta Mediterranea, stile di vita e spazio materico dell'antico vivere mediterraneo, è qui indagata nell'eterogeneità delle sue espressioni materiali e immateriali.
Riscoperte come antichi luoghi del vivere e del nutrirsi mediterraneo, le diaetae pompeiane arricchite di dipinti di giardino, evidenziano come l'atto del nutrirsi sia legato a una complessità di aspetti multisensoriali che inducono a realizzare spazi figurativi per ampliare illusoriamente lo spazio reali, oltre il confine materico della parete, valore spontaneo reinterpretato oggi dalle strategie di marketing esperienziale.
In questa ricerca, il marketing, esperienziale e territoriale, si integra con il disegno e la rappresentazione per definire, partendo dalla salvaguardia di un patrimonio intangibile, un progetto di comunicazione territoriale volto a divulgare la conoscenza del passato nel presente, in un'ottica di sviluppo futuro.
"La tutela del Patrimonio artistico". Dalla legislazione preunitaria alla legislazione fascista

description: L'uomo contemporaneo sente fortemente l'esigenza di "fermare il tempo", di "recuperarlo" nella memoria attraverso la tutela dei beni culturali in modo da restituire dei frammenti di civiltà cogliendo il senso dell'identità di un popolo. La parabola della tutela dei beni culturali segue pedissequamente l'uomo, il progredire della coscienza della propria storia che acquisisce con l'apprezzamento del progresso civile e morale. La presente ricerca è mossa dall'interesse di studiare le origini e l'evoluzione della legislazione in materia di beni culturali, di riportare i momenti e i fatti più rilevati della cultura della società italiana tentando di verificare quanto la crescita culturale, politica ed economica del paese abbiano contribuito all'evoluzione degli interventi di tutela. Questo perché l'indagine sui beni culturali non è soltanto il frutto di ricerche, testimonianze, documentazioni storiche ma anche la storia di conoscenze, di riferimenti, di rispetto di tradizioni e di affermazioni di identità, di rapporti tra cronaca, storia e memoria. Il percorso di ricerca seguendo l'avvicendarsi dei provvedimenti legislativi e delle istituzioni preposte alla tutela vuole dimostrare che il patrimonio artistico non è un carico inutilizzabile che ci trasportiamo da secoli nell'assenza di consapevolezze economiche e politiche, ma che è all'opposto, elemento di partecipazione alla consapevole predisposizione di una strategia sociale indirizzata a costruire e consolidare l'identità culturale e il senso di appartenenza alla società strutturata.
