Fear of falling : the experience of elderly individuals who have previously fallen
Creators: name: Convey, Marilynne G.
Publisher: name: University of British Columbia
Year: 2008

description: Fear of falling resulting from a previous fall has serious health implications for elderly individuals who live in the community. This fear has been linked to activity restriction, poor physical health, increased dependence, and lifestyle changes. Previous research on fear of falling has described it in relation to other outcomes of a fall and not as a discrete entity. None of the studies included the individual's perspective. Therefore, the purpose of this study was to describe the meaning of the experience of fear of falling from the perspective's of elderly individuals who have previously fallen. The phenomenological method was used to gain an understanding of the subjective experience of the nine elderly community-dwelling individuals who participated in the study. All of the participants had fallen more than once and all had sustained an injury from a fall. In the course of two or three interviews, each participant and the researcher constructed an account of the participant's experience of the fear of falling. Using content analysis the data was conceptualized into themes and concepts reflective of the participants' perspectives. The presentation of this descriptive data was organized into two major themes which represented a process of adjustment: making meaning of the experience of the fear of falling and integrating the meaning of the experience into daily living. The findings revealed that fear of falling threatened the individual's physical and psychological survival. In response a process of adjustment was initiated in which the individual used behavioural and cognitive activities that sought to maintain control and were self-enhancing. The participants' accounts of their fear of falling highlight the importance of determining the client's perspective in order to understand and work with elderly individuals who fall and are afraid of falling again. In light of the research findings implications for nursing practice, nursing education, and nursing research are discussed.

description: Σκοπός της διατριβής ήταν η μελέτη του στρες των γονέων παιδιών με αυτισμό. Εξετάστηκαν συγκεκριμένα οι παράγοντες που οι ίδιοι οι γονείς κρίνουν ως πιο στρεσογόνους. Οι παράγοντες αυτοί περιλάμβαναν συμπεριφορές που πιθανώς εμφανίζει το παιδί, καθώς και διάφορες κοινωνικό-οικονομικές συνθήκες. Σύμφωνα με τα αποτελέσματα, οι συμπεριφορικοί παράγοντες που βρέθηκαν να σχετίζονται περισσότερο με το γονικό στρες, είναι οι δυσκολίες που εμφανίζει το παιδί ως προς τις κοινωνικές του σχέσεις, τα ελλείμματα στη συγκινησιακή του αμοιβαιότητα, οι στερεοτυπικές συμπεριφορές, οι δυσκολίες στον ύπνο και τη διατροφή, οι μειωμένες ικανότητες αυτό-εξυπηρέτησης και τα προβλήματα συμπεριφοράς όπως η επιθετικότητα και οι αυτό-τραυματισμοί. Όσον αφορά τις κοικωνικό-οικονομικές συνθήκες, οι οικονομικές απαιτήσεις ανατροφής ενός παιδιού με αυτισμό, η συνεργασία με τους ειδικούς και τις υπηρεσίες, η περιορισμένη πληροφόρηση για θέματα σχετικά με τον αυτισμό, η αποδοχή του παιδιού από την κοινωνία και το μέλλον του, βρέθηκε ότι αποτελούν εξίσου στρεσογόνους παράγοντες για τους γονείς. Τα ευρήματα της έρευνας έχουν σημαντική θεωρητική και κλινική σημασία καθώς αποδεικνύουν ότι γενικότερα η ανατροφή ενός παιδιού με αυτισμό είναι αρκετά απαιτητική και έχει σημαντικό συναισθηματικό αντίκτυπο στους γονείς.
description: The purpose of the dissertation was to study the stress of parents of children with autism. The factors that parents themselves consider to be the most stressful were examined in particular. These factors included behaviors that the child may display, as well as various socio-economic conditions. According to the results, the behavioral factors that were found to be more related to parental stress, are the difficulties that the child shows in his social relationships, the deficits in his emotional reciprocity, the stereotypical behaviors, the difficulties in sleeping and eating , reduced self-care skills and behavioral problems such as aggression and self-injury. Regarding the socio-economic conditions, the financial demands of raising a child with autism, the cooperation with the specialists and the services, the limited information on issues related to autism, the acceptance of the child by the society and his future, it was found that are equally stressful for parents. The research findings are of great theoretical and clinical importance as they prove that in general the upbringing of a child with autism is quite demanding and has a significant emotional impact on parents.

description: Spin reorientation and magnetisation reversal are two important features of the rare-earth orthorhombic provskites ($RM$O$_{3}$'s) that have attracted a lot of attention, though their exact microscopic origin has eluded researchers. Here, using density functional theory and classical atomistic spin dynamics we build a general Heisenberg magnetic model that allows to explore the whole phase diagram of the chromite and ferrite compounds and to scrutinize the microscopic mechanism responsible for spin reorientations and magnetisation reversals. We show that the occurrence of a magnetization reversal transition depends on the relative strength and sign of two interactions between rare-earth and transition-metal atoms: superexchange and Dzyaloshinsky-Moriya. We also conclude that the presence of a smooth spin reorientation transition between the so-called $Γ_4$ and the $Γ_2$ phases through a coexisting region, and the temperature range in which it occurs, depends on subtle balance of metal--metal (superexchange and Dzyaloshinsky-Moriya) and metal--rare-earth (Dzyaloshinsky-Moriya) couplings. In particular, we show that the intermediate coexistence region occurs because the spin sublattices rotate at different rates.

description: This paper summarizes contributions and suggestions as presented at the Chandra Workshop Star Formation in the Era of Three Great Observatories conducted in July 2005. One of the declared goals of the workshop was to raise recognition within the star formation research community about the sensible future utilization of the space observatories Spitzer, Hubble, and Chandra in their remaining years of operation to tackle imminent questions of our understanding of stellar formation and the early evolution of stars. A white paper was generated to support the continuous and simultaneous usage of observatory time for star formation research. The contents of this paper have been presented and discussed at several other meetings during the course of 2005 and January 2006.

description: The fusion-fission process accompanied by neutron emission is studied in the superheavy-mass region on the basis of the fluctuation-dissipation model combined with a statistical model. The calculation of the trajectory or the shape evolution in the deformation space of the nucleus with neutron emission is performed. Each process (quasi-fission, fusion-fission, and deep quasi-fission processes) has a characteristic travelling time from the point of contact of colliding nuclei to the scission point. These dynamical aspects of the whole process are discussed in terms of the pre-scission neutron multiplicity, which depends on the time spent on each process. We have presented the details of the characteristics of our model calculation in the reactions $^{48}$Ca+$^{208}$Pb and $^{48}$Ca+$^{244}$Pu, and shown how the structure of the distribution of pre-scission neutron multiplicity depends on the incident energy.

description: We introduce a hierarchy of conditions necessarily satisfied by any distribution P(ab) representing the probabilities for two separate observers to obtain outcomes a and b when making local measurements on a shared quantum state. Each condition in this hierarchy is formulated as a semidefinite program. Our approach can be used to obtain upper-bounds on the quantum violation of an arbitrary Bell inequality. It yields, for instance, tight bounds for the violations of the Collins et al. inequalities.

description: Different kinds of models are used to study various natural and technical phenomena. Usually, the researcher is limited to using a certain kind of model approach, not using others (or even not realizing the existence of other model approaches). The authors believe that a complete study of a certain phenomenon should cover several model approaches. The paper describes several model approaches which we used in the study of the random early detection algorithm for active queue management. Both the model approaches themselves and their implementation and the results obtained are described.

description: We introduce a dynamical description based on a probability density $ϕ(σ,x,y,t)$ of the vorticity $σ$ in two-dimensional viscous flows such that the average vorticity evolves according to the Navier-Stokes equations. A time-dependent mixing index is defined and the class of probability densities that maximizes this index is studied. The time dependence of the Lagrange multipliers can be chosen in such a way that the masses $m(σ,t):=\intdxdy ϕ(σ,x,y,t)$ associated with each vorticity value $σ$ are conserved. When the masses $m(σ,t)$ are conserved then 1) the mixing index satisfies an H-theorem and 2) the mixing index is the time-dependent analogue of the entropy employed in the statistical mechanical theory of inviscid 2D flows [Miller, Weichman & Cross, Phys. Rev. A \textbf{45} (1992); Robert & Sommeria, Phys. Rev. Lett. \textbf{69}, 2776 (1992)]. Within this framework we also show how to reconstruct the probability density of the quasi-stationary coherent structures from the experimentally determined vorticity-stream function relations and we provide a connection between this probability density and an appropriate initial distribution.

description: Inelastic-neutron-scattering measurements were performed on a single crystal of the heavy-fermion paramagnet UTe$_2$ above its superconducting temperature. We confirm the presence of antiferromagnetic fluctuations with the incommensurate wavevector $\mathbf{k}_1=(0,0.57,0)$. A quasielastic signal is found, whose momentum-transfer dependence is compatible with fluctuations of magnetic moments $μ\parallel\mathbf{a}$, with a sine-wave modulation of wavevector $\mathbf{k}_1$ and in-phase moments on the nearest U atoms. Low dimensionality of the magnetic fluctuations, consequence of the ladder structure, is indicated by weak correlations along the direction $\mathbf{c}$. These fluctuations saturate below the temperature $T_1^*\simeq15$~K, in possible relation with anomalies observed in thermodynamic, electrical-transport and nuclear-magnetic-resonance measurements. The absence or weakness of ferromagnetic fluctuations, in our data collected at temperatures down to 2.1 K and energy transfers from 0.6 to 7.5 meV, is emphasized. These results constitute constraints for models of magnetically-mediated superconductivity in UTe$_2$.

description: Inspired by the prevalence of the class 1 subtype especially the type I-E CRISPR system in Streptomyces, here we report the development of the type I-E CRISPR system into a series of transcriptional regulation tools. We further demonstrated the effectiveness of such activators in nine phylogenetically distant Streptomyces strains. Using these tools, we successfully activated 13 out of 21 BGCs and led to the identification and characterization of one polyketide, one Ripp and three alkaloid products that have never been reported. Our work is expected to have a profound impact and to facilitate the discovery of numerous structurally diverse compounds from Streptomyces.

description: Interplanetary magnetic field magnitude fluctuations are notoriously more intermittent than velocity fluctuations in both fast and slow wind. This behaviour has been interpreted in terms of the anomalous scaling observed in passive scalars in fully developed hydrodynamic turbulence. In this paper, the strong intermittent nature of the interplanetary magnetic field is briefly discussed comparing results performed during different phases of the solar cycle. The scaling properties of the interplanetary magnetic field magnitude show solar cycle variation that can be distinguished in the scaling exponents revealed by structure functions. The scaling exponents observed around solar maximum coincide, within the errors, to those measured for passive scalars in hydrodynamic turbulence. However, it is also found that the values are not universal in the sense that the solar cycle variation may be reflected in dependence on the structure of the velocity field.

description: In the Internet of Things (IoT) era, vehicles and other intelligent components in an intelligent transportation system (ITS) are connected, forming Vehicular Networks (VNs) that provide efficient and secure traffic and ubiquitous access to various applications. However, as the number of nodes in ITS increases, it is challenging to satisfy a varied and large number of service requests with different Quality of Service and security requirements in highly dynamic VNs. Intelligent nodes in VNs can compete or cooperate for limited network resources to achieve either an individual or a group's objectives. Game Theory (GT), a theoretical framework designed for strategic interactions among rational decision-makers sharing scarce resources, can be used to model and analyze individual or group behaviors of communicating entities in VNs. This paper primarily surveys the recent developments of GT in solving various challenges of VNs. This survey starts with an introduction to the background of VNs. A review of GT models studied in the VNs is then introduced, including its basic concepts, classifications, and applicable vehicular issues. After discussing the requirements of VNs and the motivation of using GT, a comprehensive literature review on GT applications in dealing with the challenges of current VNs is provided. Furthermore, recent contributions of GT to VNs integrating with diverse emerging 5G technologies are surveyed. Finally, the lessons learned are given, and several key research challenges and possible solutions for applying GT in VNs are outlined.

Υπό αυτό το πρίσμα, στη βιβλιογραφική ανασκόπηση, εξετάζεται η έννοια της κρίσης, η τυπολογία, τα στάδια και η αντιμετώπιση των κρίσεων. Η επικοινωνία αποτελεί σημαντικό εργαλείο στην διαχείριση μιας κρίσης, για αυτό και αναλύεται χωριστά η σημασία της με αναφορά στο εσωτερικό και εξωτερικό περιβάλλον, αλλά και στο πως βοηθάει στη διαχείριση των κρίσεων. Σε περιπτώσεις κρίσεων είναι ουσιαστικό να εξεταστεί η επικοινωνιακή διαχείριση τους και το πως αυτές αντανακλούν στην εταιρική φήμη, η οποία είναι τόσο σημαντική για τις εταιρείες. Οι απειλές, ο ρόλος των ΜΜΕ και το πως μπορεί η εταιρεία να προστατεύσει την εικόνα της εν μέσω μιας κρίσης εξετάζονται ξεχωριστά. Με στόχο την υποστήριξη της θεωρίας και την εφαρμοσιμότητα της σε περιπτώσεις κρίσεων επιλέχθηκε προς ανάλυση μία από τις μεγαλύτερες κρίσεις που έχει πλήξει την αεροπορική βιομηχανία στον 21ο αιώνα και το πως η εταιρεία διαχειρίστηκε την κρίση και τις επιπτώσεις της. Συνοπτικά, ο σκοπός της εργασίας είναι η εξέταση του αντικειμένου της διαχείρισης κρίσεων και τη συσχέτισή του με τις έννοιες της επικοινωνίας και της εταιρικής φήμης. Ειδικότερα, η κρίση της Boeing με το 737 Max αποτελεί απτό παράδειγμα της μεγάλης σημασίας που έχει η διαχείριση κρίσεων στην αερoπορική βιομηχανία.
description: This thesis examines crisis management, attempting to provide an overview through the individual elements and factors which play a pivotal role. In this light, in the literature review, the concept of crisis, typology, stages and crisis management are examined. Communication is an important tool in crisis management, which is why its importance is analyzed with reference to the internal and external environment, and to how it helps in crisis management. In the event of crisis, it is important to consider the crisis communication management and how crises reflect to the corporate reputation, which is so important to companies. The threats, the role of the media and how the company can protect its image amidst a crisis are examined separately. In order to support the theory and its applicability in events of crisis, one of the biggest crises of the aviation industry in the 21st century, and how the company managed the crisis and its effects, was selected as a case study. In conclusion, the purpose of this thesis in to examine the subject of crisis management and its correlation with the concepts of communication and corporate reputation. In particular, the Boeing crisis with the 737 Max model is a tangible example of the great importance of crisis management in the aviation industry.

description: Aims. EXor-type objects are protostars that display powerful UV-optical outbursts caused by intermittent and powerful events of magnetospheric accretion. These objects are not yet well investigated and are quite difficult to characterize. Several parameters, such as plasma stream velocities, characteristic densities, and temperatures, can be retrieved from present observations. As of yet, however, there is no information about the magnetic field values and the exact underlying accretion scenario is also under discussion. Methods. We use laboratory plasmas, created by a high power laser impacting a solid target or by a plasma gun injector, and make these plasmas propagate perpendicularly to a strong external magnetic field. The propagating plasmas are found to be well scaled to the presently inferred parameters of EXor-type accretion event, thus allowing us to study the behaviour of such episodic accretion processes in scaled conditions. Results. We propose a scenario of additional matter accretion in the equatorial plane, which claims to explain the increased accretion rates of the EXor objects, supported by the experimental demonstration of effective plasma propagation across the magnetic field. In particular, our laboratory investigation allows us to determine that the field strength in the accretion stream of EXor objects, in a position intermediate between the truncation radius and the stellar surface, should be of the order of 100 gauss. This, in turn, suggests a field strength of a few kilogausses on the stellar surface, which is similar to values inferred from observations of classical T Tauri stars.

description: Azimuthal angle two particle correlations have been shown to be a powerful probe for extracting novel features of the interaction between hard scattered partons and the medium produced in Au+Au collisions at RHIC. At intermediate $p_T$, 2-5GeV/c, the jets have been shown to be significantly modified in both their particle composition and their angular distribution compared to p+p collisions. Additionally, angular two particle correlations with identified hadrons provide information on the possible role of modified hadronization scenarios such as partonic recombination, which might allow medium modified jet fragmentation by connecting hard scattered partons to low $p_T$ thermal partons. PHENIX has excellent particle identification capabilities and has developed robust techniques for extracting jet correlations from the large underlying event. We present recent PHENIX results from Au+Au collisions for a variety of $p_T$ and particle type combinations. We also present p+p measurements as a baseline. We show evidence that protons and anti-protons in the $p_T$ region of enhanced baryon and anti-baryon single particle production are produced in close angle pairs of opposite charge and that the strong modifications to the away side shape observed for charged hadron correlations are also present when baryons are correlated.

description: We introduce {\em Green fields}, as commutative Green biset functors with no non-trivial ideals. We state some of their properties and give examples of known Green biset functors which are Green fields. Among the properties, we prove some criterions ensuring that a Green field is semisimple. Finally, we describe a type of Green field for which its category of modules is equivalent to a category of vector spaces over a field.
The Effect of Orbital Eccentricity on Gravitational Wave Background Radiation from Supermassive Black Hole Binaries

description: A compact binary in an eccentric orbit radiates gravitational waves (GWs) at all integer harmonics of its orbital frequency. In this study, we investigate the effect of orbital eccentricity on the expected gravitational background radiation (GWBR) from supermassive black hole (SMBH) binaries in the nuclei of galaxies. For this purpose, we formulate a power spectrum of the GWBR from cosmological evolving eccentric binaries. Then, we apply this formulation to the case of the GWBR from SMBH binaries. The key to doing this is to correctly estimate the number density of coalescing SMBH binaries. In this study, we use a semi-analytic model of galaxy and SMBH formation. We find that the power spectrum of the GWBR from SMBH binaries on eccentric orbits is suppressed for frequencies $f \lesssim 1~{\rm nHz}$ if the initial eccentricity, $e_0$, satisfies $e_0 > 0.2$ and the initial semi-major axis is 300 times Scwarzschild radius. Our model predicts that while the overall shape and amplitude of the power spectrum depend strongly on the processes of galaxy formation, the eccentricity of binaries can affect the shape of the power spectrum for lower frequencies, i.e., $f \lesssim 1~{\rm nHz}$. Pulsar timing measurements, which can detect GW in this frequency range, could constrain the effect of eccentricity on the power spectrum of the GWBR from SMBH binaries.

description: Although considerable efforts have been devoted to transformer-based ranking models for document search, the relevance-efficiency tradeoff remains a critical problem for ad-hoc ranking. To overcome this challenge, this paper presents BECR (BERT-based Composite Re-Ranking), a composite re-ranking scheme that combines deep contextual token interactions and traditional lexical term-matching features. In particular, BECR exploits a token encoding mechanism to decompose the query representations into pre-computable uni-grams and skip-n-grams. By applying token encoding on top of a dual-encoder architecture, BECR separates the attentions between a query and a document while capturing the contextual semantics of a query. In contrast to previous approaches, this framework does not perform expensive BERT computations during online inference. Thus, it is significantly faster, yet still able to achieve high competitiveness in ad-hoc ranking relevance. Finally, an in-depth comparison between BECR and other start-of-the-art neural ranking baselines is described using the TREC datasets, thereby further demonstrating the enhanced relevance and efficiency of BECR.

description: We present an automated procedure for the derivation of atmospheric parameters (Teff, log g, [M/H]) and individual chemical abundances from stellar spectra. The MATrix Inversion for Spectral SythEsis (MATISSE) algorithm determines a basis, B_θ(λ), allowing to derive a particular stellar parameter θby projection of an observed spectrum. The B_θ(λ) function is determined from an optimal linear combination of theoretical spectra and it relates, in a quantitative way, the variations in the spectrum flux with variations in θ. An application of this method to the GAIA/RVS spectral range is described, together with its performances for different types of stars of various metallicities. Blind tests with synthetic spectra of randomly selected parameters and observed input spectra are also presented. The method gives rapid, accurate and stable results and it can be efficiently applied to the study of stellar populations through the analysis of large spectral data sets, including moderate to low signal to noise spectra.
Dust environment of active asteroids P/2019 A4 (PANSTARRS) and P/2021 A5 (PANSTARRS)

description: We report on the characterisation of the dust activity and dynamical evolution of two faint active asteroids, P/2019 A4, and P/2021 A5, observed with the 10.4m GTC using both imaging and spectroscopy. Asteroid P/2019 A4 activity is found to be linked to an impulsive event occurring some $\pm$10 days around perihelion, probably due to a collision or a rotational disruption. Its orbit is stable over 100 Myr timescales. Dust tail models reveal a short-term burst producing (2.0$\pm$0.7)$\times$10$^6$ kg of dust for maximum particle radius rmax=1 cm. The spectrum of P/2019 A4 is featureless, and slightly redder than the Sun. P/2021 A5 was active $\sim$50 days after perihelion, lasting $\sim$5 to $\sim$60 days, and ejecting (8$\pm$2)$\times$10$^6$ kg of dust for rmax=1 cm. The orbital simulations show that a few percent of dynamical clones of P/2021 A5 are unstable on 20-50 Myr timescales. Thus, P/2021 A5 might be an implanted object from the JFC region or beyond. These facts point to water ice sublimation as the activation mechanism. This object also displays a featureless spectrum, but slightly bluer than the Sun. Nuclei sizes are estimated in the few hundred meters range for both asteroids. Particle ejection speeds ($\sim$0.2 m/s) are consistent with escape speeds from those small-sized objects.

description: Nuclides sharing the same mass number (isobars) are observed ubiquitously along the stability line. While having nearly identical radii, stable isobars can differ in shape, and present in particular different quadrupole deformations. We show that even small differences in these deformations can be probed by relativistic nuclear collisions experiments, where they manifest as deviations from unity in the ratios of elliptic flow coefficients taken between isobaric systems. Collider experiments with isobars represent, thus, a unique means to obtain quantitative information about the geometric shape of atomic nuclei.

Teacher education and professional development of educators

description: Clinical teachers work between clinical and academic settings and therefore it is difficult to know, without examining unique contexts, exactly what skills are required for them to excel in the role. A critical social theory paradigm informed the design of this multi-phase thesis involving separate qualitative, quantitative, and action-based studies. The following phases were completed: 1. An integrated review of the literature on clinical teaching, followed by an initial exploratory study, using Interpretive Description to understand the experiences of clinical teachers working in diverse Australian environments. 2. A quantitative cross-sectional survey study that examined the capabilities of Australian clinical teachers in order to highlight collective strengths and weaknesses. 3. A participatory action research study, involving a team of clinical teachers, to collaboratively develop a new approach to professional development that would strengthen capabilities 4. A concept analysis of borders – a construct that uniquely affects clinical teachers who occupy the two worlds of clinical practice and tertiary education, contributes new knowledge. The qualitative exploration found that clinical teachers experience many role challenges and some rewards; and revealed ways clinical teachers could prepare to excel in the role. The national survey revealed that Australian clinical teachers have strong capabilities in some clinical teaching domains such as building teaching relationships; however, they lacked capability in leadership and research skills. The action research study led to the collaborative design of meaningful professional development, and some organisational changes intended to enhance clinical teacher professional identity. The changes included the widespread dissemination, and use of, a printed charter explaining the clinical teacher role, and a series of podcasts that illuminated insights about the role for new and emerging clinical teachers. The idea for a concept analysis emerged during the action research study and contributed new theoretical concepts and a unique model. Clinical teachers who understand that learning how to negotiate the borders of the nursing clinical and academic worlds may be a keyway for them to flourish and develop a robust professional identity.

description: We present an analytically solvable 3D light-front Hamiltonian model for hadrons that extends light-front holography by including finite mass quarks and a longitudinal confinement term. We propose that the model is suitable as an improved analytic approximation to QCD at a low resolution scale. We demonstrate that it preserves desired Lorentz symmetries and it produces improved agreement with the experimental mass spectroscopy and other properties of the light mesons. Importantly, the model also respects chiral symmetry and the Gell-Mann-Oakes-Renner relation.

Using Pseudo-Stochastic Rational Languages in Probabilistic Grammatical Inference

description: In probabilistic grammatical inference, a usual goal is to infer a good approximation of an unknown distribution P called a stochastic language. The estimate of P stands in some class of probabilistic models such as probabilistic automata (PA). In this paper, we focus on probabilistic models based on multiplicity automata (MA). The stochastic languages generated by MA are called rational stochastic languages; they strictly include stochastic languages generated by PA; they also admit a very concise canonical representation. Despite the fact that this class is not recursively enumerable, it is efficiently identifiable in the limit by using the algorithm DEES, introduced by the authors in a previous paper. However, the identification is not proper and before the convergence of the algorithm, DEES can produce MA that do not define stochastic languages. Nevertheless, it is possible to use these MA to define stochastic languages. We show that they belong to a broader class of rational series, that we call pseudo-stochastic rational languages. The aim of this paper is twofold. First we provide a theoretical study of pseudo-stochastic rational languages, the languages output by DEES, showing for example that this class is decidable within polynomial time. Second, we have carried out a lot of experiments in order to compare DEES to classical inference algorithms such as ALERGIA and MDI. They show that DEES outperforms them in most cases.
