description: Due to high performance demand and varied usage requirements from computer systems, the complexity of design has been increasing. This is reflected in popularity of Application Specific ICs and accelerators along with traditional general-purpose processors. This complexity in the design makes verification of the chips extremely crucial and challenging. As the design gets bigger, the state space of the design blows away, also known as ‘State Space Explosion'. It becomes difficult to completely verify all the functionalities and properties as defined in architecture specification using simulation-based verification. Simulation-based verification continues to be the primary technique for hardware verification due to its scalability and ease of use. The main challenge is to come up with a specific input test stimulus which would excite a particular logic or which would result in a particular state of design after certain cycles. Also, these test cases are hand-written by verification engineer, the person is expected to know the design well and has to use the prior knowledge and experience to come up with a directed test case. In addition to this, the test cases change from design to design and this whole method is not portable. Therefore, we propose a machine learning driven pattern recognition based test sequence generation, which can improve coverage and reachability of hard-to-hit states, enhance functional verification without the exploration of whole state space. ML algorithms can be used to change knobs which affect the constraints in the randomization step of test sequence generation in order to hit low reachable states.

description: Partendo dai primi tentativi di emancipazione della donna e di una letteratura “al femminile” tra gli ultimi decenni dell’Ottocento e i primi del secolo scorso, si analizzano, alla luce di alcuni testi esemplari, le componenti fondamentali del femminismo letterario “maturo” così come si sono manifestate soprattutto negli anni Settanta del Novecento. Ne emergono non solo temi e motivi fondamentali, a partire dal capovolgimento dei tradizionali modelli comportamentali sul piano socio-antropologico, ma anche moduli narrativi autonomi, per la prima volta utilizzati dalle donne autrici e protagoniste delle proprie opere, attraverso la conquista di un inedito punto di vista e la pratica di un linguaggio, che consente al soggetto femminile di penetrare nel corpo della lingua per meglio esprimere le sue spesso inconfessabili esperienze esistenziali.
description: Starting from the first attemps of emancipation of the woman and a “Feminine” literaturebetween the last decades of the nineteenth century and the beginning of the last century, we analyze, in the light of some exemplary texts, the fundamental components of “mature” literary feminism as menifested especially in the 1970s. Not only fundamental attempts and reasons emerge, starting from the reversal of the traditional behavioral models on the socio-anthropological level, but also autonomous narrative modules, used for the first time by women authors and protagonists of their works, through the conquest of an unprecedented point of view and the practice of a language, which allows the female subject to penetrate the body of the language to better express her often unmentionable existential experiences.

description: A major problem resulting from the massive use of social media is the potential spread of incorrect information. Yet, very few studies have investigated the impact of incorrect information on individual and collective decisions. We performed experiments in which participants had to estimate a series of quantities, before and after receiving social information. Unbeknownst to them, we controlled the degree of inaccuracy of the social information through ‘virtual influencers’, who provided some incorrect information. We find that a large proportion of individuals only partially follow the social information, thus resisting incorrect information. Moreover, incorrect information can help improve group performance more than correct information, when going against a human underestimation bias. We then design a computational model whose predictions are in good agreement with the empirical data, and sheds light on the mechanisms underlying our results. Besides these main findings, we demonstrate that the dispersion of estimates varies a lot between quantities, and must thus be considered when normalizing and aggregating estimates of quantities that are very different in nature. Overall, our results suggest that incorrect information does not necessarily impair the collective wisdom of groups, and can even be used to dampen the negative effects of known cognitive biases.

description: We analyse the distribution of secure keys using quantum cryptography based on the continuous variable degree of freedom of entangled photon pairs. We derive the information capacity of a scheme based on the spatial entanglement of photons from a realistic source, and show that the standard measures of security known for quadrature-based continuous variable quantum cryptography (CV-QKD) are inadequate. A specific simple eavesdropping attack is analysed to illuminate how secret information may be distilled well beyond the bounds of the usual CV-QKD measures.

description: There are many important considerations for collaborations. Collaborations involve teams of different personalities, often approaching the project from different disciplines and backgrounds. Misunderstandings and disagreements could disrupt the collaborative process. Successful collaborations often share key characteristics that help ensure members of the team are working well together. These include: Commitment to stated shared research goals and values for the project and collaboration. Respectful and equitable environment in which each voice, intellectual input, and direction of the project, or specific components of the project is valued. Trust, physical and psychological safety, and mutual respect must be present among all members of the collaboration. Openness and transparency about team member and the project’s progress, challenges that may occur, financial issues, etc. Agreed upon processes for professional communication in person, via email, and in virtual environments. For interdisciplinary teams – clarity about disciplinary frameworks and terminology, clear and precise interactions, particularly for multinational teams—mapping out how all are accommodated All members should take responsibility for individual work and feel ownership for the success of the overall project such that the project contributes to intellectual and career growth for all.
Bloated Stars as AGN Broad Line Clouds: The Emission Line Spectrum
Creators: name: Alexander, Tal
name: Netzer, Hagai
Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The Bloated Stars Scenario proposes that AGN broad line emission originates in the winds or envelopes of bloated stars (BS). Its main advantage over BLR cloud models is the gravitational confinement of the gas and its major difficulty the large estimated number of BSs and resulting high mass loss rate. We calculate the emission line spectrum by a detailed numerical photoionization code for a wide range of wind structures and a detailed QSO nucleus model with L(ion)=7E45 erg/s, M(bh)=8E7 Mo. The size and boundary density of the wind are determined by various processes: Comptonization by the central ionizing source (calculated self consistently), tidal disruption by the black hole and the limit set by the wind's finite mass. We find that the emission spectrum is mainly determined by the conditions at the boundary of the line emitting fraction of the wind rather than by its internal structure. Comptonization results in very high ionization parameters at the boundary which produces an excess of unobserved broad high excitation forbidden lines. The finite mass constraint limits the wind size, increases the boundary density and thus improves the results. Slow decelerating mass-constrained flows with high gas densities (1E8-1E12 cm^-3) are as success- ful as clouds in reproducing the observed lines. Only 5E4 dense wind BSs are required in the inner 1/3 pc. This small fraction approaches that of super- giants (SG) in the solar neighborhood and the mass loss is consistent with the observational constraints. The BS number is a very sensitive function of the wind structure. SG-like BSs are ruled out by their high mass loss. BSs with dense winds can reproduce the BLR line spectrum and be supported by the stellar population without excessive mass loss and collisional destruction rates.

description: Il saggio tratta di un’opera che ha affrontato dei temi sensibili del Novecento, che ragiona su alcuni dei protagonisti del secolo e li ritrae nel pieno della loro ascesa al potere: “Tecnica del colpo di Stato” di Curzio Malaparte. La “Tecnica”, pubblicata in Francia nel 1931 (e in Italia nel 1948 per Bompiani), ha consacrato Malaparte alla fama europea. Per diversi motivi, la sua vicenda è stata avvincente e di lungo corso specialmente in Russia, dove l’opera ha raggiunto il grande pubblico a cavallo tra il secolo scorso e il nostro. Si intende mostrare come uno dei maggiori interpreti del Novecento sia stato interpretato dalla cultura sovietica e russa, portando nel nuovo millennio tematiche che, pur sembrando ancorate a un dato momento storico, tendono ad essere universali e che, pur parlando dell’ascesa al potere dei totalitarismi del Novecento, dialogano con problematiche del tutto attuali.
description: This essays deals with a book that has faced some of the most sensitive themes of the Twentieth Century, portraying its main characters while conquering power positions: Curzio Malaparte’s’Tecnica del colpo di Stato’. The book was written in 1930, after a travel in 1939 URSS, was published in France in 1931 and in Italy in 1948, for the editor Bompiani. It compares techniques and strategies of several putschs, combining political analysis and litarary fiction. In these pages Mussolini, Hitler, Lenin, Trockij and Stalin act like Malaparte’s characters, struggled with their power strategies, which have been described very varefully by the Author.

La splendida Dafne è protagonista, com’è noto, di una metamorfosi vegetale. L’artista torinese eredita, a questo riguardo, la grande tradizione poetica della metamorfosi ovidiana riscontrabile sia nei numerosi versi dedicati a Dafne, sia in pittura nel grande carrubo intitolato “Daphne” (1974).
description: Carlo Levi has conveyed some variaions to Daphne’sportrait involving either verse, prose or painting, as indeed he had already done with the Narcissus’ portrait, the mythological figure laying at the heart of his ‘poiesis’. The beautiful nymph is the protagonist, as it is known, of a plant metamorphosis. The Turin artist inherits, tothis respect, the great poetic tradition of Ovid’s ‘Metamorphoses’, that can be found both in the verses and prose devoted to Daphne, and in painting with the great carob of 1974 entitled ‘Daphne’.

description: We study E-eigenvalues of a symmetric tensor $f$ of degree $d$ on a finite-dimensional Euclidean vector space $V$, and their relation with the E-characteristic polynomial of $f$. We show that the leading coefficient of the E-characteristic polynomial of $f$, when it has maximum degree, is the $(d-2)$-th power (respectively the $((d-2)/2)$-th power) when $d$ is odd (respectively when $d$ is even) of the $\widetilde{Q}$-discriminant, where $\widetilde{Q}$ is the $d$-th Veronese embedding of the isotropic quadric $Q\subseteq\mathbb{P}(V)$. This fact, together with a known formula for the constant term of the E-characteristic polynomial of $f$, leads to a closed formula for the product of the E-eigenvalues of $f$, which generalizes the fact that the determinant of a symmetric matrix is equal to the product of its eigenvalues.

description: A recent article by Galtier and Nazarenko [1] proposed that weakly nonlinear gravitational waves could result in a turbulent cascade, with energy flowing from high to low frequency modes or vice versa. This is an interesting proposition for early universe cosmology because it could suggest some "natural" initial conditions for the gravitational background. In this paper we use the ADM formalism to show that, given some simple and, arguably, natural assumptions, such initial conditions lead to expansion (or collapse) of the spacetime on a timescale much faster than that of the turbulent cascade, meaning that the cascade is unlikely to have sufficient time to develop under general conditions. We suggest possible ways in which the expansion could be mitigated to give the cascade time to develop.

description: Lo studio intende passare in rassegna immagini di viaggi e naufragi presenti nel Canzoniere di Umberto Saba. Se nelle Poesie dell’adolescenza e giovanili il viaggio richiama moduli fiabeschi, costituendosi come vero e proprio sogno infantile, nelle liriche di Parole e Mediterranee al tono favoloso si sovrappone il richiamo al mito, in particolare nel riferimento ad Ulisse. Eppure in Cielo (in Uccelli: «Non chiedo altro. / Fumare / la mia pipa in silenzio come un vecchio / lupo di mare»), il messaggio definitivo che il poeta ci consegna è quello di un vecchio marinaio sazio di viaggi e derive, un tempo sospinto eternamente al largo, e infine rimasto a contemplare, dalla riva e dalla distanza offerta dal tempo, le tappe della propria vita.
description: In this tudy we intend to review images of sea voyages and shipwrecks in Umberto Saba’s ‘Canzoniere’. If in ‘Poesie dell’adolescenza e giovanili’ the sea voyage recalls fabulous forms, constituting itself as a child’s dream, in the lyrics of ‘Parole’ and ‘Mediterranee’ the fabulous tone is a accompanied by the reference to the myth, in particular to Ulysses. However in ‘Cielo’ (in ‘Uccelli: «Non chiedo altro. / Fumare / la mia pipa in silenzio come un vecchio / lupo di mare»), the poet looks like an old sailor full of sea voyages, tiredof being pushed eternally offshore, and remained to conteplate his life from the shore and the distance offered by time.

description: We solve the quantum constraints for homogeneous N=1 supergravity on 3-geometries with a Bianchi IX metric. Because these geometries admit Killing vectors with the same commutation relations as the angular momentum generators, there are two distinct definitions of homogeneity. The first of these is well-known and has been shown by D'Eath to give the wormhole state. We show that the alternative definition of homogeneity leads to the Hartle-Hawking ``no boundary" state.

description: The primordial helium abundance $Y_P$ is calculated using sulphur as metallicity tracer in the classical methodology (with $Y_P$ as an extrapolation of $Y$ to zero metals). The calculated value, $Y_{P,\,S}=0.244\pm0.006$, is in good agreement with the estimate from the Planck experiment, as well as, determinations in the literature using oxygen as the metallicity tracer. The chemical analysis includes the sustraction of the nebular continuum and of the stellar continuum computed from simple stellar population synthesis grids. The $S^{+2}$ content is measured from the near infrared $\left[SIII\right]λ\lambda9069Å,9532Å$ lines, while an $ICF\left(S^{3+}\right)$ is proposed based on the $Ar^{3+}/Ar^{2+}$ fraction. Finally, we apply a multivariable linear regression using simultaneously oxygen, nitrogen and sulphur abundances for the same sample to determine the primordial helium abundance resulting in $Y_{P-O,\,N,\,S}=0.245\pm0.007$

La scelta di analizzare nel dettaglio questi interventi è determinata dalla concordanza di argomento riscontrata negli scritti di Ugo Fleres che pubblicò, a sua volta, una serie di articoli riguardo il medesimo evento, tra il settembre e il dicembre del 1895, su «La Critica» diretta da Monaldi. Particolare attenzione sarà dedicata, infatti, all’influenza che il sodalizio intellettuale con Ugo Fleres esercitò sulla critica d’arte pirandelliana. I rispettivi scritti aprono la questione su altro punto di contatto fondamentale che merita un momento di riflessione particolare e cioè la teoria critica, già qui riscontrabile, che si basa sul sincerismo, concetto poi abbondantemente spiegato e discusso nell’esperienza editoriale e intellettuale di «Ariel» che nascerà di lì a poco.
description: In this essays I will analyze the pages of art criticism written by Pirandello between 1895 and 1896 on the Esposizione di Belle Arti in Rome, published in the «Giornale di Sicilia». The choice to analyze these interventions is determined by the concordance of the argument found in the writings of Ugo Flores who published, in turn, a series of articles dealing with the same event, in «La Critica» directed by Monaldi between September and December 1895. I will focus particular attention, to the influence exerted by the intellectual partnership with Ugo Flores on Pirandello’s art criticism. The respective writings open the question on another fundamental contact point that deserves further consideration: the critical theory, already foundhere, based on the concept of sincerismo, is explained and discussed in the editorial and intellectual experience of «Ariel» which will born soon.

description: The electromagnetic box diagram for the leptonic decays of pseudoscalar mesons in the quark model is evaluated to all orders in ${\bf p} / m_q$, where ${\bf p}$ is the relative three-momentum of the quark-antiquark pair and $m_q$ is the quark mass. We compute $B_P \equiv Γ(η\to l^+ l^-) / Γ(η\to γγ)$ using a popular nonrelativistic (NR) harmonic oscillator wave function, and with a relativistic momentum space wave function that we derive from the MIT bag model. We also compare with a calculation in the limit of extreme NR binding due to Bergström. Numerical calculations of $B_P$ using these three parameterizations of the wave function agree to within a few percent over a wide kinematical range. We find that the quark model leads in a natural way to a negligible value for the ratio of dispersive to absorptive parts of the electromagnetic amplitude for $η\to μ^+ μ^-$ (unitary bound). However we find substantial deviations from the unitary bound in other kinematical regions, such as $η,π^0 \to e^+ e^-$. These quark models yield $B(η\to μ^+μ^-) \approx 4.3 \times 10^{-6}$, within errors of the recent SATURNE measurement of $5.1 \pm 0.8 \times 10^{-6}$, $B(η\to e^+ e^-) \approx 6.3 \times 10^{-9}$, and $B(π^0 \to e^+ e^-) \approx 1.0 \times 10^{-7}$.

The First Hours of the GW170817 Kilonova and the Importance of Early Optical and Ultraviolet Observations for Constraining Emission Models

description: The kilonova associated with GW170817 displayed early blue emission which has been interpreted as a signature of either radioactive decay in low-opacity ejecta, relativistic boosting of radioactive decay in high-velocity ejecta, the cooling of material heated by a wind or by a "cocoon" surrounding a jet, or a combination thereof. Distinguishing between these mechanisms is important for constraining the ejecta components and their parameters, which tie directly into the physics we can learn from these events. I compile published ultraviolet, optical, and infrared light curves of the GW170817 kilonova and examine whether the combined data set can be used to distinguish between early-emission models. The combined optical data show an early rise consistent with radioactive decay of low opacity ejecta as the main emission source, but the subsequent decline is fit well by all models. A lack of constraints on the ultraviolet flux during the first few hours after discovery allows for both radioactive decay and other cooling mechanisms to explain the early bolometric light curve. This analysis demonstrates that early (few hours after merger) high-cadence optical and ultraviolet observations will be critical for determining the source of blue emission in future kilonovae.

description: Intento dell’articolo è quello di indagare l’intreccio di letteratura e arte nell’opera di Leonardo Sciascia, e in particolar modo nella sua produzione lirica, attestata dalla silloge del ’52 “La Sicilia, il suo cuore” e da alcuni versi inediti e dispersi. Pur non ascrivibile ad una poetica ben definita – tra ascendenze crepuscolari e suggestioni ermetiche, prosasticità e lirismo – la sua opera in versi è emblematica dell’interesse figurativo dell’autore, come rivela la presenza di una vera e propria iconografia del paesaggio ispirata ai dipinti di alcuni grandi maestri del Novecento – da Chagall a Mirò – o dell’arte sacra – come Benozzo Gozzoli – attraverso i quali lo scrittore dà forma alla sua visione della realtà. Emerge l’affresco di una Sicilia arida e desolata, illuminata a tratti da squarci di luce, che si erge a potente metafora del mondo.
description: The aim of article is to investigate the interconnection of literature and art in Leonardo Sciascia, and especially in his lyric production, attested by 1952 anthology ‘Sicily, its heart’ and some unpublished and scattered verses. Although his poetry is not attributable to a defined poetics – between crepuscolar derivation and hermetic suggestions, narrative trend and lyricism –it testifies to the author’s figurative interest, as revealed by the landscape representation, inspired by the paintings of some great artists of the Twentieth Century – from Chagall to Mirò – or of sacred art – like Benozzo Gozzoli – through which the writer creates his vision of reality. The portrayalof a dry and desolate Sicily emerges, occasionally illuminated by patches of light, which stand sas a powerful as a metaphor for the world.

I discorsi su «un’arte di Stato» partono già dai primi anni successivi alla Marcia su Roma, per poi proseguire negli anni Trenta. L’«arte fascista» vuole essere un’arte profondamente realista, vicina al racconto fedele del popolo, della sua quotidianità e dei nuovi modelli di vita. In campo letterario si sviluppò un forte dibattito teorico sulle forme del romanzo fascista, un romanzo che doveva essere anch’esso realista e vicino agli spazi quotidiani degli uomini. A differenza del progetto architettonico, però, il progetto romanzo – proprio come quello cinematografico – non trovò una piena realizzazione pratica.
description: Fascism has always had a keen interest in the development of an artistic season that could be an expression of the new Italian politicalcourse. Speechesabout «the art of the nation» start as early as the first years after the March on Rome, and then continue along the 1930s. The «fascist art» wants to be a profoundly realistic art, close to the faithful story of the people, of their everyday life and new life patterns. In the literary field there was a strong theoretical debate about the forms of fascist novel, a novel that had to be realistic and close to daily spaces of men. Unlike the architectural project, howeever, the novel project – just like the cinematographic project – did not find a full protical realization.

description: We consider collisional properties of weakly bound heteronuclear molecules (dimers) formed in a two-species mixture of atoms with a large mass difference. We focus on dimers containing light fermionic atoms as they manifest collisional stability due to an effective dimer-dimer repulsion originating from the exchange of the light atoms. In order to solve the dimer-dimer scattering problem we develop a theoretical approach, which provides a physically transparent and quantitative description of this four-atom system in terms of three- and two-body observables. We calculate the elastic scattering amplitude and the rates of inelastic processes such as the trimer formation and the relaxation of dimers into deeply bound molecular states. Irrespective of whether the heavy atoms are bosons or fermions, the inelastic rate can be significantly lower than the rate of elastic collisions. Moreover, the measurement of the inelastic rate which is a four-body observable, can be an efficient and precise tool for determining three-body observables such as the three-body parameter, positions of Efimov states and their lifetimes.

description: Partendo da una riflessione sull’età medievale e di come essa viene genericamente percepita dalla società contemporanea, ci si propone di condurre un’indagine sull’effettiva “transmedialità” di un romanzo storico, postmoderno, ambientato nell’età di mezzo, quale “Il nome della rosa” di Umberto Eco. Un’opera che presenta una struttura che ben si presta ad una migrazione dalla “lettera” alla “voce” e che, difatti, è stata prima rielaborata in una pellicola cinematografica e poi rimodulata in una serie televisiva. Attraverso l’analisi del processo di transmediazione in ambiti prettamente performativi, si è scoperto che le tecniche e le modalità utilizzate si avvicinano molto a quelle impiegate dai giullari, in epoca medievale, per la trasmissione della cultura e della letteratura dell’epoca. Il risultato finale è la creazione di opere artistiche diverse tra loro, non sovrapponibili ma affini perché hanno in comune lo stesso archetipo, discendendo da un’unica tradizione letteraria autoriale. In una società che ha perso il suo ruolo centrale nell’educazione culturale delle masse, il processo di transmedialità è fondamentale per far sì che un testo, attraverso un procedimento di rilettura e rielaborazione venga “riattivato” secondo nuove modalità e finalità di ricezione che consentano ad un pubblico poco avvezzo alla lettura di “godere” del messaggio letterario.
description: Starting from a reflexion on the Middle Ages and how this periodi s usually conceived by contemprary society. This paper intends to investigate the “transmediality” of a postmodern historical novel, set in the Middle Ages, such as Umberto Eco’s ‘The Namen of the Rose’. This work presents a structure that may easily migrate from the “letter” to the “voice” and has in fact been rewoeked as a film and, more recently, as a television series. By snslysing the process of transmediation from a preformative viewpoint, it appears that the tecniques and means employed are similar to those used by jonglrurs in the Middle Ages in the transmission of culture and literature. The final autcome of this processi s to create works that are different from each other, that may not be superimposed, but which are alike in that they derive from the same archetype, since they descend from a single authoritative literary tradition. In a society that has ceased to the cultural education of the masses, the process of transmediality is fundamentalin ensuring that a text, through a process of rereading and reworking, may be reassessed in the light of new means and aims of reception which enable an audience no longer familiar with reading to enioy the litarary message.

description: Quantum spin liquids attract great interest due to their exceptional magnetic properties characterized by the absence of long-range order down to low temperatures despite the strong magnetic interaction. Commonly, these compounds are strongly correlated electron systems, and their electrodynamic response is governed by the Mott gap in the excitation spectrum. Here we summarize and discuss the optical properties of several two-dimensional quantum spin liquid candidates. First we consider the inorganic material Herbertsmithite ZnCu$_3$(OH)$_6$Cl$_2$ and related compounds, which crystallize in a kagome lattice. Then we turn to the organic compounds $β^{\prime}$-EtMe$_3$\-Sb\-[Pd(dmit)$_2$]$_2$, $κ$-(BEDT-TTF)$_2$Ag$_2$(CN)$_3$ and $κ$-(BEDT-TTF)$_2$Cu$_2$(CN)$_3$, where the spins are arranged in an almost perfect triangular lattice, leading to strong frustration. Due to differences in bandwidth, the effective correlation strength varies over a wide range, leading to a rather distinct behavior as far as the electrodynamic properties are concerned. We discuss the spinon contributions to the optical conductivity in comparison to metallic quantum fluctuations in the vicinity of the Mott transition.

From the Owl to the Eskimo: the Radiation-Gasdynamics of Planetary Nebulae IV

description: We present the results of two-dimensional radiation-gasdynamic simulations of aspherical Planetary Nebulae (PNe) evolution. These simulations were constructed using the Generalized Interacting Stellar Winds (GISW) scenario of Balick (1987) where a fast, tenuous wind from the central star expands into a toroidal, slow, dense wind. We demonstrate that the GISW model can produce a wide range of aspherical flow patterns. We have constructed self-consistent synthetic observations of the models from forbidden line emissivities used in the energy loss term. We present integrated intensity and long-slit spectrum, (Position-Velocity) maps of the models projected at different angles on the sky. These synthetic observations are compared with real intensity and Position-Velocity maps of PNe. We find that there is a very good match between the synthetic and real observations in terms of morphologies, kinematics, and physical conditions. From the results of these simulations we conclude that the GISW scenario can account for most, if not all, PNe morphologies, thus confirming Balick's (1987) conjecture.

"I found myself staying" - A case study of the job embeddedness and retention of qualified health workers in rural and remote areas of Uganda

description: Global health worker maldistribution affects poor countries and rural areas most adversely, despite their high disease burden. Health workers reject rural areas due to isolation, and lack of facilities. Recommended extrinsic interventions to address rural-urban imbalance are costly and not sustainable in most developing countries. However, some health workers serve in rural areas without such interventions, suggesting existence of strong intrinsic motives for rural practice choice and retention, knowledge of which could be used to select retainable staff. This PhD research, a mixed-methods case study of 50 purposively-selected doctors and nurses retained in 12 Ugandan rural government and private general hospitals for three or more years, sought to find the reasons some qualified health workers get retained in rural areas, and the role of job embeddedness, a construct which predicts employee turnover, in their retention. Rural practice choices were made for personal or altruistic reasons and in obedience to authorities. Rural integration and embeddedness depended upon social and pre-service technical preparation, leading to cultural competence, adaptability, self-efficacy and resilience to shocks. Retention depended on feeling satisfied with achievements or self-adjustment. Despite a modest average degree of rural job embeddedness, rural retention averaged 19 years and most participants did not intend to leave soon. Job embeddedness predicted the duration of retention but not intention to leave. The strongest dimensions of job embeddedness were “fit-organisation” and “fit-community”. Prosocial behaviour and self-efficacy in rural practice influence rural practice choice and retention, and job embeddedness generally increases with retention. The study contributes the job embeddedness construct to the theory of health worker retention research. It also extends the use of the construct to mixed-methods studies, raises rural retention to the policy and research agendas and highlights the role of prosocial behaviour, self-efficacy and good managerial practices in rural practice choice and retention.

description: Single crystals of the methylammonium (MA) lead halides MAPbI3, MAPbBr3, and MAPbCl3 have been investigated using infrared spectroscopy with the aim of analyzing structural and dynamical aspects of processes that enable the ordering of the MA molecule in the orthorhombic crystal structure of these hybrid perovskites. Our temperature-dependent studies were focused on the analysis of the CH/NH rocking, C-N stretching, and CH/NH bending modes of the MA molecule in the 800-1750 cm-1 frequency range. They deliver a direct comparison of the behavior of the three halides on crossing the orthorhombic-tetragonal phase transition in MA lead halide single crystals. Drastic changes of all vibrational modes close to the phase transition were clearly observed. Additional spectral features that were not discussed previously are pointed out. The transformation of the 2-dimensional orthorhombic hydrogen bond layers into a more 3-dimensional arrangement in the tetragonal phase seems to be an important feature providing deeper insight into the mechanisms that lead to a free-rotating MA molecule in the inorganic host structure. The change of the molecules site symmetry in the tetragonal crystal structure seems to be an important feature of the orthorhombic-tetragonal phase transition. For low temperatures it can be stated that the iodide is stronger influenced by hydrogen bonding than the bromide and the chloride.

description: Il saggio indaga la posizione assunta da Alberto Moravia rispetto alla contestazione giovanile del ’68, e la sua difesa dell’intellettuale, dell’artista dalle accuse degli studenti universitari. Il romanziere intervenne a più riprese sul movimento sia nelle pagine di «Nuovi Argomenti» sia su «L’Espresso», ma anche a posteriori dialogando con Alain Elkann e con Enzo Siciliano, ribadendo un concetto cardine: il ’68 aveva il merito di aver mutato i rapporti fra genitori e figli, insegnanti e allievi, ma rimaneva un movimento velleitario, confuso, senza precisi obiettivi. Ambivalente, dunque, l’atteggiamento del romanziere: affascinato dal movimento, ma al contempo, a mente fredda, ne riconosce l’insufficienza, la disorganicità, il velleitarismo.
description: The present study musess on Alberto Moravia’s attitude towards the youth protest in 1968 and his defence of the intellectual and artist from the charges of university students. The writer commented on the movement many times from the pages of “Nuovi argomenti”, and “L’Espresso”, but also afterwards, in dialugue with Alain Elkan and Enzo Siciliano, by stressing a pivotal idea: the 1968 youth protests had changed the relationships between parents and children, teachers and students; however, it remained an over-ambitious and confused movement, with no percise objective. Thus, he kept a double perspective: on the one hand, he was intrigued by the protest; on the other hand, and unemotionally, he recognized the inadequate, patchy and unrealistic nature of themovement.
