description: Among spin-crossover complexes, Fe-porphyrin (FeP) stands out for molecular spintronic applications: An intricate, yet favourable balance between ligand fields, charge transfer, and the Coulomb interaction makes FeP highly manipulable, while its planar structure facilitates device integration. Here, we theoretically design a mechanical spin-switch device in which external strain triggers the intrinsic magneto-structural coupling of FeP through a purely organic embedding. Exploiting the chemical compatibility and stretchability of graphene nanoribbon electrodes, we overcome common reliability and reproducibility issues of conventional inorganic setups. The competition between the Coulomb interaction and distortion-induced changes in ligand fields requires methodologies beyond the state-of-the-art: Combining density functional theory with many-body techniques, we demonstrate experimentally feasible tensile strain to trigger a low-spin ($S=1$) to high-spin ($S=2$) crossover. Concomitantly, the current through the device toggles by over an order of magnitude, adding a fully planar mechanical current-switch unit to the panoply of molecular spintronics.

description: Aims: Massive stars in low-metallicity environments may produce exotic explosions such as long-duration gamma-ray bursts and pair-instability supernovae when they die as core-collapse supernovae (CCSNe). Here we determine the feasibility of searching for these CCSNe in metal-poor dwarf galaxies using various survey strategies. Methods: We determine oxygen abundances and star-formation rates for all spectroscopically typed star-forming galaxies in the Sloan Digital Sky Survey, Data Release 5, within z = 0.04. We then estimate the CCSN rates for sub-samples of galaxies with differing upper-metallicity limits. Using Monte-Carlo simulations we then predict the fraction of these CCSNe that we can expect to detect using different survey strategies. Results: Using a single 2m telescope (with a standard CCD camera) search we predict a detection rate of ~1.3 CCSNe/yr in galaxies with metallicities below 12 + log(O/H) < 8.2 which are within a volume that will allow detailed follow-up with 4m and 8m telescopes (z = 0.04). With a network of seven 2m telescopes we estimate ~9.3 CCSNe/yr could be found, although this would require more than 1,000 hrs of telescope time allocated to the network. Within the same radial distance, a volume-limited search in the future Pan-STARRS PS1 all-sky survey should uncover 12.5 CCSNe/yr in low-metallicity galaxies. Over a period of a few years this would allow a detailed comparison of their properties. We then extend our calculations to determine the total numbers of CCSNe that can potentially be found in magnitude-limited surveys with PS1 (24,000/yr, within z < 0.6), PS4 (69,000/yr, within z < 0.8) and LSST (160,000/yr, within z < 0.9) surveys.

Charismatic leadership : effects of leadership style and group productivity on individual adjustment and performance
Creators: name: Howell, Jane Mary
Publisher: name: University of British Columbia
Year: 2010

description: The present study examined the effects of three leadership styles (charismatic, structuring, and considerate) and two levels of group productivity (high and low) on individuals' adjustment to and performance on an ambiguous decision making task. One hundred and forty-four Commerce undergraduates participated in a simulated organization (The Mackenzie Institute) which was obstensibly designed to assess their practical business skills. They completed an in-basket exercise directed by a manager (an experimental confederate) who portrayed a charismatic, structuring, or considerate leadership style. Participants individually worked on the exercise in the presence of two other Commerce students (also experimental confederates) who advocated to them either high or low productivity on the task. The participants subsequently completed a questionnaire measuring their adjustment to the task, the manager, and the two student confederates. Univariate analyses of variance generally indicated that individuals with charismatic leaders had significantly higher task performance, task adjustment, and adjustment to the leader when compared to individuals with considerate or structuring leaders. The group productivity data indicated that individuals in the high productivity group reported a significantly greater task satisfaction, lower role conflict and higher adjustment to the group than individuals in the low productivity group. Croup productivity norms had no significant effect on individual task performance. The interaction between leadership style and group productivity revealed that charismatic leadership, regardless of the directionality of group productivity norms, produced high individual task performance, task adjustment, and adjustment to the leader and to the group. In contrast, the impact of structuring leadership on individuals' task adjustment was modified by group productivity norms: individuals who worked with a structuring leader and in a high productivity group reported higher task satisfaction and lower role conflict than individuals who worked with a structuring leader and in a low productivity group. Individuals with a considerate leader and in a high productivity group had significantly higher task satisfaction than those with a considerate leader and in a low productivity group. Multivariate analyses of the data revealed a similar pattern of results. Explanations and implications of the results are discussed and directions for future research are presented.

description: A charge injection technique is applied to the X-ray CCD camera, XIS (X-ray Imaging Spectrometer) onboard Suzaku. The charge transfer inefficiency (CTI) in each CCD column (vertical transfer channel) is measured by the injection of charge packets into a transfer channel and subsequent readout. This paper reports the performances of the charge injection capability based on the ground experiments using a radiation damaged device, and in-orbit measurements of the XIS. The ground experiments show that charges are stably injected with the dispersion of 91eV in FWHM in a specific column for the charges equivalent to the X-ray energy of 5.1keV. This dispersion width is significantly smaller than that of the X-ray events of 113eV (FWHM) at approximately the same energy. The amount of charge loss during transfer in a specific column, which is measured with the charge injection capability, is consistent with that measured with the calibration source. These results indicate that the charge injection technique can accurately measure column-dependent charge losses rather than the calibration sources. The column-to-column CTI correction to the calibration source spectra significantly reduces the line widths compared to those with a column-averaged CTI correction (from 193eV to 173eV in FWHM on an average at the time of one year after the launch). In addition, this method significantly reduces the low energy tail in the line profile of the calibration source spectrum.

description: The superalgebra of $\Z_2^2$-graded supersymmetric quantum mechanics is shown to be realizable in terms of a single bosonic degree of freedom. Such an approach is directly inspired by a description of the corresponding $\Z_2$-graded superalgebra in the framework of a Calogero-Vasiliev algebra or, more generally, of a generalized deformed oscillator algebra. In the case of the $\Z_2^2$-graded superalgebra, the central element $Z$ has the property of distinguishing between degenerate eigenstates of the Hamiltonian.

description: The 5/2 fractional quantum Hall effect in the second Landau level of extremely clean two-dimensional electron gases has attracted much attention due to its topological order predicted to host quasiparticles that obey non-Abelian quantum statistics and could serve as a basis for fault-tolerant quantum computations. While previous works have establish the Fermi liquid (FL) nature of its putative composite fermion (CF) normal phase, little is known regarding its thermodynamics properties and as a result its effective mass is entirely unknown. Here, we report on time-resolved specific heat measurements at filling factor 5/2, and we examine the ratio of specific heat to temperature as a function of temperature. Combining these specific heat data with existing longitudinal thermopower data measuring the entropy in the clean limit we find that, unless a phase transition/crossover gives rise to large specific heat anomaly, both datasets point towards a large effective mass in the FL phase of CFs at 5/2. We estimate the effective-to-bare mass ratio m*/me to be ranging from ~2 to 4, which is two to three times larger than previously measured values in the first Landau level.
THE IMPACT OF PATIENT SHIELDING ON RADIATION EXPOSURE IN DIAGNOSTIC X-RAYS: A SYSTEMATIC REVIEW

description: This systematic review examines the impact of patient shielding on radiation exposure during diagnostic X-ray examinations. Shielding has traditionally been used to protect patients from unnecessary radiation, particularly to sensitive areas such as the thyroid, gonads, and breast tissue. With advancements in radiological technology and evolving safety guidelines, the role of shielding is being reevaluated. This review synthesizes evidence from recent studies, analyzing the effectiveness of shielding in reducing radiation doses across various types of diagnostic X-rays, including dental, chest, and abdominal imaging. The results suggest that while shielding can reduce exposure in certain contexts, its effectiveness varies based on the type of examination and shielding material used. Moreover, recent debates challenge the necessity of shielding, with some arguing that modern equipment already minimizes exposure. The review also identifies inconsistencies in shielding practices and emphasizes the need for updated guidelines based on technological advancements. Future research should focus on optimizing shielding practices and exploring alternative methods for minimizing radiation risks in diagnostic imaging.

description: We report extraordinary effects in the transmission of sound through periodically perforated plates, supported by both measurements and theory. In agreement with recent observations in slit arrays [M. H. Lu et al. Phys. Rev. Lett. 99, 174301 (2007)], nearly full transmission is observed at certain resonant frequencies, pointing out at similarities of the acoustic phenomena and their optical counterpart. However, acoustic screening well beyond that predicted by the mass law is achieved over a wide range of wavelengths in the vicinity of the period of the array, resulting in fundamentally unique behavior of the sound as compared to light. The randomness of the hole distribution and the impedance contrast between the fluid and the solid plate are found to play a crucial role.

description: The nucleation of vapor bubbles within a superheated fluid is studied using density functional theory. The nudged elastic band technique is used to find the minimum energy pathway from the metastable uniform liquid to the stable uniform gas thus emphasizing the analogy between the the nucleation problem and that of chemical reactions. The result is both an accurate determination of the critical nucleus and an unbiased description of the density profile at various points along the path between the free energy extrema. This calculation is compared to two other methods: the use of parametrized profiles and constrained minimization of the free energy. The results indicate that the recent claim, based on the constraint method, that bubble nucleation and growth involves an activated instability is incorrect.

description: We investigate an evolutional scenario of the FRW universe with the Casimir energy scaling like $(-)(1+z)^4$. The Casimir effect is used to explain the vacuum energy differences (its value measured from astrophysics is so small compared to value obtained from quantum field theory calculations). The dynamics of the FRW model is represented in terms of a two-dimensional dynamical system to show all evolutional paths of this model in the phase space for all admissible initial conditions. We find also an exact solution for non flat evolutional paths of Universe driven by the Casimir effect. The main difference between the FRW model with the Casimir force and the $Λ$CDM model is that their generic solutions are a set of evolutional paths with a bounce solution and an initial singularity, respectively. The evolutional scenario are tested by using the SNIa data, FRIIb radiogalaxies, baryon oscillation peak and CMB observation. We compare the power of explanation of the model considered and the $Λ$CDM model using the Bayesian information criterion and Bayesian factor. Our investigation of the information criteria of model selection showed the preference of the $Λ$CDM model over the model considered. However the presence of negative like the radiation term can remove a tension between the theoretical and observed primordial ${}^4$He and D abundance.

description: Pratiche religiose, cultura migratoria e immaginario migratorio
nell’Africa sub-sahariana: i contesti senegalese e guineano
La combinazione di diversi fattori (storici, religiosi, politici, economici) fa sì che sempre più africani subsahariani considerino la migrazione un’alternativa alle molte difficoltà locali. In alcune comunità sub-sahariane, forgia una vera cultura della mobilità, predisponendole o supportandole nella formazione e nell’esecuzione del progetto di
migrazione. Tra questi fattori, l’articolo pone l’accento sulle pratiche religiose, nel loro ruolo di ispirazione, predisposizione e sostegno alla migrazione dei sub-sahariani, in particolare senegalesi e guineani. Si tratta di pratiche, credenze e altri rituali religiosi che interagiscono con il progetto e l’atto migratorio come un vero “ammortizzatore” che riduce l’intensità e l’impatto di molteplici “shock” legati alla migrazione. Il ricorso dei migranti e delle loro famiglie a pratiche religiose rafforza e modula il progetto migratorio al fine di anticipare e / o meglio accogliere le difficoltà derivante dall’incontro tra l’immaginario e la realtà migratoria.

Religious practices, migratory culture and migratory imagery
in sub-Saharan Africa: the Senegalese and Guinean contexts
The combination of different factors (historical, religious, political, economic) means that more and more Sub-Saharan Africans consider migration as an alternative to the many local difficulties. In some Sub-Saharan communities the combination forge a true culture of mobility, predisposing and supporting the formation and the execution of the migration project. Among these factors, the article focuses on religious practices in their role of inspiration, predisposition and support to the migration of Sub-Saharans, especially Senegalese and Guineans. These practices, beliefs and other religious rituals, interact with the project and with the migratory act as a real “shock absorber” that reduces the intensity and the impact of multiple “shocks” related to migration.
The use of religious practices strengthens and modulates the migration project to anticipate and / or to better accommodate the shock due to the intersection between the imaginary and the migratory reality.

description: A simple class of unitary renormalization group transformations that force hamiltonians towards a band-diagonal form produce few-body interactions in which low- and high-energy states are decoupled, which can greatly simplify many-body calculations. One such transformation has been applied to phenomenological and effective field theory nucleon-nucleon interactions with success, but further progress requires consistent treatment of at least the three-nucleon interaction. In this paper we demonstrate in an extremely simple model how these renormalization group transformations consistently evolve two- and three-body interactions towards band-diagonal form, and introduce a diagrammatic approach that generalizes to the realistic nuclear problem.

description: Evaluating industrial impact on society and environment. Proposals for indicators from a paradigmatic case of cement production in Umbria
Gubbio is one of the most famous towns in Umbria, but only a few know its main economic activity: the production of cement. In Gubbio, in fact, for about a century two important factories have been producing cement. Their impact on the environment and public health has been recently discussed by a part of the local community. Although industrial emissions respect the limits established by law, some residents have organized a committee for the protection of environment and health in the territory of Gubbio. They ask for further investigation, especially on the epidemiological field.
In this regard, the community is divided, because the two cement factories and other firms joined to them represent a crucial resource for local employment and economy. In the background, the institutions that since World War II have been connected to the left, which are traditionally more sensitive to environmental themes, appear unwilling to really face the issue and mention the encouraging data on the emissions released by these factories. This paradigmatic case may provide indicators for a proper assessment of complex implications of the relationship industry-environment-health.

Evaluation de l’impact industriel sur la société et l’environnement.
Propositions d’indicateurs à partir d’un cas paradigmatique de production de ciment en Ombrie
Gubbio est l’un des centres les plus connus de l’Ombrie, mais presque personne ne connaît sa principale activité économique: la production du ciment. Depuis presqu’un siècle, à Gubbio sont en fonction deux usines de ciment, dont l’impact sur l’environnement et sur la santé des habitants a été mis en question par la communauté locale. Malgré les émissions des établissements industriels soient conformes à la loi, on a récemment constitué un comité qui vise à protéger l’environnement et la santé et qui demande d’ultérieures recherches épidémiologiques. À ce propos, l’opinion de la communauté n’est pas unanime étant donné que les deux usines et les sociétés associées constituent une source fondamentale pour l’emploi et pour l’économie locale.
De l’autre côté, les institutions politiques, guidées depuis l’après-guerre par les partis de gauche, les plus sensibles aux problèmes de l’environnement, se montrent timides mais confortés par les données rassurantes des contrôles des émissions. Ce cas paradigmatique peut fournir des indicateurs pour une évaluation correcte des implications complexes de la relation industrie-environnement-santé.

description: Dissipative processes acting in rotating neutron stars are essential in preventing the growth of the r-mode instability. We estimate the damping time of r-modes of an hypothetical compact quark star made up by color flavor locked quark matter at a temperature $T \lesssim 0.01$ MeV. The dissipation that we consider is due to the the mutual friction force between the normal and the superfluid component arising from the elastic scattering of phonons with quantized vortices. This process is the dominant one for temperatures $T \lesssim 0.01$ MeV where the mean free path of phonons due to their self-interactions is larger than the radius of the star and they can be described as an ideal bosonic gas. We find that r-modes oscillations are efficiently damped by this mechanism for pulsars rotating at frequencies of the order of 1 Hz at most. Our analysis rules out the possibility that cold pulsars rotating at higher frequencies are entirely made up by color flavor locked quark matter.

description: “Il bosco degli urogalli” di Mario Rigoni Stern come un atlante
narrativo: leggere la raccolta di racconti attraverso l’immaginazione
cartografica
Partendo dal riconoscimento dell’importanza dei testi letterari quali voci attive del discorso geografico, lo scopo di questo contributo è quello di esplorare le potenzialità interpretative della comparazione fra un genere cartografico – l’atlante – e un genere letterario, la raccolta di racconti. Il bosco degli urogalli (1962), raccolta dello scrittore Mario Rigoni Stern, è qui analizzata come un atlante narrativo capace di costruire le proprie geografie (Brosseau, 1995), e di orientare lo sguardo del lettore nelle geografie del mondo. L’analisi si concentra in particolare su tre temi spaziali che emergono dalla raccolta: la transcalarità e le topografie che fanno della raccolta dello scrittore vicentino un atlante delle geografie aperte dell’Altopiano di Asiago; il peculiare concetto di natura che emerge dalla relazione fra i racconti; la materializzazione narrativa dei
rapporti fra spazio e tempo che trasformano la raccolta in un atlante temporale. La metafora dell’atlante è inoltre accompagnata da alcune geo-visualizzazioni narrative atte a a proporre un possibile atlante materiale de Il bosco degli urogalli.

A partir de la reconnaissance de l’importance des textes littéraires comme voix actives dans le discours géographique, l’objectif de cette contribution est d’explorer le potentiel d’interprétation de la comparaison entre un genre cartographique – l’atlas – et un genre littéraire, la collection d’histoire courte. La Chasse aux coqs de bruyère, collection
de l’écrivain Mario Rigoni Stern, est analysée ici comme un atlas narratif capable de construire sa propre géographie (Brosseau, 1995), et capable de guider l’oeil du lecteur dans la géographie du mond. L’analyse porte notamment sur trois thèmes spatiaux qui se dégagent de la collection: les différentes échelles et topographies qui font la collection de l’écrivain a un atlas de la géographie «ouvert» de le Plateau de Asiago; le particulière concept de la nature qui se dégage de la relation entre les histoires; la matérialisation narrative de la relation entre l’espace et le temps qui transforme la collection en un atlas de la tempête. La métaphore de l’atlas est aussi accompagnée par des cartes narratives visant à proposer un atlas possible de La Chasse aux coqs de
bruyère.

description: Agricoltura, ecomusei e identità locali in Friuli Venezia Giulia (Italia)
Il lavoro prende in esame le realtà ecomuseali presenti sul territorio della regione Friuli Venezia Giulia, analizzandone il ruolo significativo nell’azione di salvaguardia e promozione dei valori identitari locali, soprattutto nei contesti rurali. In particolare, ad essere approfonditi sono da un lato la mappa di comunità, fondamentale strumento per l’autoriconoscimento e per rafforzare il senso di appartenenza di una comunità, dall’altro le produzioni agricole tradizionali come opportunità di recupero
identitario e allo stesso tempo occasione di attivazione di circuiti di economia sostenibile e di qualità.

Agriculture, écomusées et identités locales en Friuli Venezia Giulia (Italie)
La recherche examine le système et les caractères des écomusées de la région Frioul Vénetie Julienne, et en analyse le rôle précieux dans l’action de sauvegarde et de la mise en valeur des identités locales avec leurs propres différences spécifiques, surtout dans les milieux ruraux. En particulier, l’on a approfondi deux sujets, c’est-à-dire, d’une part, les parish maps, instrument fondamental pour l’auto-reconnaissance et
pour renforcer le sentiment d’appartenance d’une communauté; et, d’autre part, les productions agricoles traditionnelles, qui représentent soit une opportunité pour récupérer les identités culturelles historiques soit une occasion pour le développement des filières liées à l’économie durable et de qualité.

description: The paper focuses on discrete-type approximations of solutions to non-homogeneous stochastic differential equations (SDEs) involving fractional Brownian motion (fBm). We prove that the rate of convergence for Euler approximations of solutions of pathwise SDEs driven by fBm with Hurst index $H>1/2$ can be estimated by $O(δ^{2H-1})$ ($δ$ is the diameter of partition). For discrete-time approximations of Skorohod-type quasilinear equation driven by fBm we prove that the rate of convergence is $O(δ^H)$.

description: Dilemma: riqualificazione del paesaggio o conservazione della viticoltura a bassa crescita? Il caso di studio di Tramonti (Liguria, Italia)

Tramonti (La Spezia) si trova all’interno del sito UNESCO “Porto Venere, Cinque Terre e le isole Palmaria, Tino e Tinetto” ed è Patrimonio dell’Umanità per i caratteri originali del paesaggio a terrazze coltivate a vite. Il comune della Spezia ha promosso un progetto-pilota sul recupero di un’area terrazzata privata, data in concessione per 20 anni ad un’associazione, che si occuperà della sua manutenzione e della coltivazione della vite attualmente in abbandono seguendo i nuovi tipi di coltura ‘alta’ per permettere lo sfalcio del prato incolto solo in corrispondenza dell’apparato radicale in contrasto con quella storica coltivata ‘bassa’ per adattarsi meglio alle difficili condizioni ambientali, di cui oggi restano solo alcuni ‘relitti’. Nasce un dilemma: è preferibile l’indirizzo perseguito dal comune, che se funziona permette il recupero di molti terrazzamenti abbandonati, oppure la conservazione ‘anacronistica’ e quasi impossibile della coltivazione a vite bassa?

Dilemme: amélioration du paysage ou conservation des vignes avec une faible croissance? L’étude de cas de Tramonti (Ligurie, Italie)
Tramonti (La Spezia) se trouve dans le site du patrimoine mondial de l’UNESCO “Porto Venere, Cinque Terre et les îles de Palmaria, Tino et Tinetto” et est un site du patrimoine mondial par les caractères originaux de la terrasse du paysage de vignes.
La municipalité de La Spezia a lancé un projet pilote sur la reprise de la zone de terrasse privée, compte tenu d’une concession pour 20 ans avec l’association, qui sera responsable de l’entretien et de la culture de vit actuellement à abandonné à la suite des nouveaux types de cultures «élevé» pour permettre la tonte de la pelouse envahie seulement à la racine cultivée en contraste avec l’historique «faible» pour mieux
s’adapter à des conditions environnementales difficiles, dont certains restent aujourd’hui seulement “épaves”. Naissance d’un dilemme: l’adresse est préférable poursuivi par la municipalité, si cela fonctionne qui permet la récupération de nombreuses terrasses abandonnées, ou le maintien de la «anachronique» et presque impossible culture des vignes basses?

description: We present numerical simulations of how a 120 M$_\odot$ primordial star regulates star formation in nearby cosmological halos at $z \sim$ 20 by photoevaporation. Our models include nine-species primordial chemistry and self-consistent multifrequency conservative transfer of UV photons with all relevant radiative processes. Whether or not new stars form in halos clustered around a Population III star ultimately depends on their core densities and proximity to the star. Diffuse halos with central densities below 2 - 3 cm$^{-3}$ are completely ionized and evaporated anywhere in the cluster. Evolved halos with core densities above 2000 cm$^{-3}$ are impervious to both ionizing and Lyman-Werner flux at most distances from the star and collapse as quickly as they would in its absence. Star formation in halos of intermediate density can be either promoted or suppressed depending on how the I-front remnant shock compresses, deforms and enriches the core with H$_2$. We find that the 120 M$_\odot$ star photodissociates H$_2$ in most halos in the cluster but that catalysis by H- restores it a few hundred kyr after the death of the star, with little effect on star formation. Our models exhibit significant departures from previous one-dimensional spherically-symmetric simulations, which are prone to serious errors due to unphysical geometric focusing effects.

description: We investigate the 2D behavior of one-fold selfintersecting, topologically stabilized center-vortex loops in the confining phase of an SU(2) Yang-Mills theory. This coarse-graining is described by curve-shrinking evolution of center-vortex loops immersed in a flat 2D plane driving the renormalization-group flow of an effective `action'. We observe that the system evolves into a highly ordered state at finite noise level, and we speculate that this feature is connected with 2D planar high $T_c$ superconductivity in $FeAs$ systems.

description: A DC electrical current is injected through a chain of metallic beads. The electrical resistances of each bead-bead contacts are measured. At low current, the distribution of these resistances is large and log-normal. At high enough current, the resistance distribution becomes sharp and Gaussian due to the creation of microweldings between some beads. The action of nearby electromagnetic waves (sparks) on the electrical conductivity of the chain is also studied. The spark effect is to lower the resistance values of the more resistive contacts, the best conductive ones remaining unaffected by the spark production. The spark is able to induce through the chain a current enough to create microweldings between some beads. This explains why the electrical resistance of a granular medium is so sensitive to the electromagnetic waves produced in its vicinity.

description: We present the first calculation of saltation transport and dune formation on Mars and compare it to real dunes. We find that the rate at which grains are entrained into saltation on Mars is one order of magnitude higher than on Earth. With this fundamental novel ingredient, we reproduce the size and different shapes of Mars dunes, and give an estimate for the wind velocity on Mars.

description: We obtain, via the Gauss-Codazzi formalism, the expression of the effective Einstein-Brans-Dicke projected equations in a non-$\mathbb{Z}_{2}$ symmetric braneworld scenario which presents hybrid compactification. It is shown that the functional form of such equations resembles the one in the Einstein's case, except by the fact that they bring extra informations in the context of exotic compactifications.

description: With current near-infrared (NIR) instruments the near-infrared light scattered from interstellar clouds can be mapped over large areas. The surface brightness carries information on the line-of-sight dust column density. Therefore, scattered light could provide an important tool to study mass distribution in quiescent interstellar clouds at a high, even sub-arcsecond resolution. We wish to confirm the assumption that light scattering dominates the surface brightness in all NIR bands. Furthermore, we want to show that scattered light can be used for an accurate estimation of dust column densities in clouds with Av in the range 1-15mag. We have obtained NIR images of a quiescent filament in the Corona Australis molecular cloud. The observations provide maps of diffuse surface brightness in J, H, and Ks bands. Using the assumption that signal is caused by scattered light we convert surface brightness data into a map of dust column density. The same observations provide colour excesses for a large number of background stars. These data are used to derive an extinction map of the cloud. The two, largely independent tracers of the cloud structure are compared. Results. In regions below Av=15m both diffuse surface brightness and background stars lead to similar column density estimates. The existing differences can be explained as a result of normal observational errors and bias in the sampling of extinctions provided by the background stars. There is no indication that thermal dust emission would have a significant contribution even in the Ks band. The results show that, below Av=15mag, scattered light does provide a reliable way to map cloud structure. Compared with the use of background stars it can also in practice provide a significantly higher spatial resolution.
