description: In 1985, Boshernitzan showed that a minimal (sub)shift satisfying a linear block growth condition must have a bounded number of ergodic probability measures. Recently, this bound was shown to be sharp through examples constructed by Cyr and Kra. In this paper, we show that under the stronger assumption of eventually constant growth, an improved bound exists. To this end, we introduce special Rauzy graphs. Variants of the well-known Rauzy graphs from symbolic dynamics, these graphs provide an explicit description of how a Rauzy graph for words of length n relates to the one for words of length n+1 for each n = 1,2,3...

description: One of the main undertakings of research in the field of didactics is the forming of elements of knowledge supporting the professionalization of teachers. These may include theoretical and interpretative constructions and hypotheses to be provided to operators as tools, so that their work, models, devices or vocational training practices can be analyzed and developed in line with the complex and dynamic nature of teaching. In this second direction, the article presents and discusses a research path directed at creating an online teacher training prototype. Indications relating to the potential effectiveness of the device emerge within the context of the teacher training issue and the requirements of research and development in the fields of pedagogy and didactics. Insegnanti in Formazione. Percorsi online per la formazione dei docenti. Una ricerca-sviluppo Uno dei principali compiti della ricerca in campo didattico è costituito dalla costruzione di elementi di sapere di supporto alla professionalizzazione di docenti. Può trattarsi di costrutti ed ipotesi teorico-interpretative da consegnare agli operatori quali strumenti di analisi e sviluppo del loro operato o di modelli, dispositivi, pratiche di formazione professionale coerenti con la natura complessa e dinamica dell’azione di insegnamento. In questa seconda direzione, l’articolo presenta e discute un percorso di ricerca finalizzato all’elaborazione di un prototipo per la formazione online dei docenti. Emergono indicazioni sull’efficacia potenziale del dispositivo, nel quadro del problema della formazione in servizio degli insegnanti e dei compiti della ricerca-sviluppo in ambito pedagogico-didattico.

description: It is generally recognized that a distinguishing feature of life is its peculiar capability to avoid equilibration. The origin of this capability and its evolution along the timeline of abiogenesis is not yet understood. We propose to study an analog of this phenomenon that could emerge in non-biological systems. To this end, we introduce the concept of sustainability of transient kinetic regimes. This concept is illustrated via investigation of cooperative effects in an extended system of compartmentalized chemical oscillators under batch and semi-batch conditions. The computational study of a model system shows robust enhancement of lifetimes of the decaying oscillations which translates into the evolution of the survival function of the transient non-equilibrium regime. This model does not rely on any form of replication. Rather, it explores the role of a structured effective environment as a contributor to the system-bath interactions that define non-equilibrium regimes. We implicate the noise produced by the effective environment of a compartmentalized oscillator as the cause of the lifetime extension.

The model is successfully used to model the reflectivity profile of a thin (16 bilayers) DMPC sample under applied osmotic pressure and the diffuse scattering from a thick (800 bilayers) stack. We compare our model to previously existing theories.

Year: 2016

description: Mobile has become the preferred way for internet access. This important change has generated transformations “equally important” in education and teaching fields, significantly increasing the importance of mobile learning. Using the User-Centered Design and Participatory Planning methodologies, 20 university students were involved in the mobile course model design, defined as “USiena model”. The objective of this research was to compare the model course designed with a model course used by other institutions present in iTunesU platform, hereinafter described as a “Sparring model”. Using the experimental method, 32 students were involved in a “pilot study” built to evaluate the learning level of both models, comparing the knowledge acquired by learners. The experimental hypothesis was that the USiena model, compared to the Sparring model, would facilitate the contents transmission to learners improving learning. The results of the experimentation confirmed our hypothesis. Mobile learning: una comparazione sull’acquisizione della conoscenza utilizzando due modelli di corso Il mobile è diventato la modalità privilegiata per l’accesso a internet. Questo importante cambiamento ha generato trasformazioni “altrettanto importanti” nel campo dell’istruzione e dell’insegnamento, facendo aumentare sensibilmente l’importanza dell’apprendimento in mobilità. Utilizzando le metodologie dello User-Centered Design e del Participatory Planning, 20 studenti universitari sono stati coinvolti nella progettazione di un modello di corso mobile, da ora in avanti definito come “modello USiena”. L’obiettivo della presente ricerca era di comparare il modello di corso che è stato progettato, con uno dei modelli di corso utilizzati da altre istituzioni presenti nella piattaforma iTunesU, di seguito descritto come “modello Sparring”. Utilizzando il metodo sperimentale, 32 studenti sono stati coinvolti in uno “studio pilota” costruito per valutare il livello di apprendimento di entrambi i modelli, comparandone l’acquisizione della conoscenza da parte dei discenti. L’ipotesi sperimentale era che il modello USiena, rispetto al modello Sparring, facilitasse la trasmissione dei contenuti verso i discenti migliorando l’apprendimento. I risultati della sperimentazione hanno confermato la nostra ipotesi.

Inclusion in school. A study of pre- e in-service teachers’ perceptions

Publisher: name: Form@re - Open Journal per la formazione in rete
Year: 2016

description: Teachers’ perceptions and attitudes toward inclusion and disability play a central and predictive role for the fulfillment and management of inclusive didactic-educational practices. The paper presents an exploratory-descriptive study conducted between 2013 and 2015. It aims to examine the teachers’ perceptions about disability and inclusion. For this purpose, 16 focus groups were conducted. On the narrative corpus of the discussions, was carried out qualitative analysis aimed to identify the cultural repertoires that have most characterized the participants’ perceptions. The study shows that the teachers have a narrow perception about inclusion, too deeply rooted to support activities. However, it is perceived as a key: an inalienable right and a project of social justice that affects everyone. L’inclusione a scuola. Una ricerca sulle percezioni di un gruppo di insegnanti in formazione e in servizio Le percezioni e gli atteggiamenti degli insegnanti verso l’inclusione e la disabilità svolgono un ruolo centrale e predittivo per la messa in campo e la gestione di pratiche didattico-educative inclusive. L’articolo presenta uno studio descrittivo-esplorativo condotto tra il 2013 e il 2015 finalizzato a esaminare le percezioni dei docenti riguardanti la disabilità e l’inclusione. A questo scopo, sono stati condotti sedici focus group. Sul corpus narrativo delle discussioni è stata effettuata un’analisi qualitativa volta a identificare i repertori culturali che hanno maggiormente caratterizzato la percezione dei partecipanti. La ricerca mostra che gli insegnanti hanno una percezione riduttiva dell’inclusione, troppo radicata al deficit e alle attività di sostegno. Tuttavia, essa è percepita come fondamentale: un diritto inalienabile e un progetto di giustizia sociale che interessa tutti.

description: Ivette Landrian Daly: Management of Traumatically Luxated Permanent Teeth: A Retrospective Study       (Under the direction of Lorne D. Koroluk)       The International Association of Dental Traumatology guidelines state that teeth must be repositioned after luxation injuries, however, the specific method of repositioning has not been specified. The purpose of this study was to compare pulpal and periodontal outcomes of digitally and orthodontically repositioned incisors following extrusive and lateral luxation.       The study sample was comprised of 80 (32 females, 48 males) subjects with 126 teeth treated for lateral and extrusive luxation injuries. Forty-one teeth were orthodontically repositioned, 67 teeth digitally repositioned and 18 teeth had mixed treatment. Overall, 35.7% of the teeth required follow up endodontic treatment. Follow up treatment was required in 19.5% of the orthodontically repositioned teeth, 40.3% of the digitally repositioned teeth and 55.6% of the mixed treatment teeth. There was a statistically significant difference in the frequency of follow up endodontic treatment between the three groups; the orthodontically repositioned teeth required less intervention (p=0.02).

description: We consider a model for a Planck scale ultraviolet cutoff which is based on Shannon sampling. Shannon sampling originated in information theory, where it expresses the equivalence of continuous and discrete representations of information. When applied to quantum field theory, Shannon sampling expresses a hard ultraviolet cutoff in the form of a bandlimitation. This introduces nonlocality at the cutoff scale in a way that is more subtle than a simple discretization of space: quantum fields can then be represented as either living on continuous space or, entirely equivalently, as living on any one lattice whose average spacing is sufficiently small. We explicitly calculate vacuum entanglement entropies in 1+1 dimension and we find a transition between logarithmic and linear scaling of the entropy, which is the expected 1+1 dimensional analog of the transition from an area to a volume law. We also use entanglement entropy and mutual information as measures to probe in detail the localizability of the field degrees of freedom. We find that, even though neither translation nor rotation invariance are broken, each field degree of freedom occupies an incompressible volume of space, indicating a finite information density.

description: We are developing further our earlier suggestion to use hyperbolic Anosov C-systems for the Monte-Carlo simulations in high energy particle physics. The hyperbolic dynamical systems have homogeneous instability of all trajectories and as such they have mixing of all orders, countable Lebesgue spectrum and positive Kolmogorov entropy. These extraordinary ergodic properties follow from the C-condition introduced by Anosov. The C-condition defines a rich class of dynamical systems which span an open set in the space of all dynamical systems. The important property of C-systems is that they have a countable set of everywhere dense periodic trajectories and that their density exponentially increases with entropy. Of special interest are C-systems that are defined on a high dimensional torus. The C-systems on a torus are perfect candidates to be used for Monte-Carlo simulations. Recently an efficient algorithm was found, which allows very fast generation of long trajectories of the C-systems. These trajectories have high quality statistical properties and we are suggesting to use them for the QCD lattice simulations and at high energy particle physics.

description: As climate change increasingly threatens agricultural production, expanding genetic diversity in crops is an important strategy for climate resilience in many agricultural contexts. In this Essay, we explore the potential of crop biotechnology to contribute to this diversification, especially in industrialized systems, by using historical perspectives to frame the current dialogue surrounding recent innovations in gene editing. We unearth comments about the possibility of enhancing crop diversity made by ambitious scientists in the early days of recombinant DNA and follow the implementation of this technology, which has not generated the diversification some anticipated. We then turn to recent claims about the promise of gene editing tools with respect to this same goal. We encourage researchers and other stakeholders to engage in activities beyond the laboratory if they hope to see what is technologically possible translated into practice at this critical point in agricultural transformation.

description: In this article, we show that eigenenergies and eigenstates of a system consisting of four one-dimensional hard-core particles with masses $6m$, $2m$, $m$, and $3m$ in a hard-wall box can be found exactly using Bethe Ansatz. The Ansatz is based on the exceptional affine reflection group $\tilde{F}_{4}$ associated with the symmetries and tiling properties of an octacube---a Platonic solid unique to four dimensions, with no three-dimensional analogues. We also uncover the Liouville integrability structure of our problem: the four integrals of motion in involution are identified as invariant polynomials of the finite reflection group $F_{4}$, taken as functions of the components of momenta.

description: Gaussian distributions are widely used in Bayesian variational inference to approximate intractable posterior densities, but the ability to accommodate skewness can improve approximation accuracy significantly, when data or prior information is scarce. We study the properties of a subclass of closed skew normals constructed using affine transformation of independent standardized univariate skew normals as the variational density, and illustrate how it provides increased flexibility and accuracy in approximating the joint posterior in various applications, by overcoming limitations in existing skew normal variational approximations. The evidence lower bound is optimized using stochastic gradient ascent, where analytic natural gradient updates are derived. We also demonstrate how problems in maximum likelihood estimation of skew normal parameters occur similarly in stochastic variational inference, and can be resolved using the centered parametrization. Supplemental materials are available online.

description: Two recent surveys have reported widely differing prevalence rates for posttraumatic stress disorder (PTSD) within the U.K. police force. Stevelink et al. (2020) reported a rate of 3.9% whereas a survey conducted for the charity Police Care UK reported a rate of 20.6%. In this comment we discuss how definitions and methodological factors can impact prevalence rates. We consider a number of possible reasons for the discrepancy between the surveys, and conclude that it is most likely a method artefact. Stevelink et al.'s survey reported the prevalence of recent-onset DSM-IV PTSD only, whereas the Police Care UK survey reported the total ICD-11 PTSD and Complex PTSD prevalence, regardless of when in the person's career the traumatic events occurred. Analysing the Police Care UK data using Stevelink et al.'s procedures produced practically identical prevalence rates, suggesting that the discrepancy was apparent rather than real.

title: How The Truth Commission got its reconciliation
Creators: name: Holbrook, Rosalind
Publisher: name: University of Kent
Year: 2022

description: This thesis explains how the truth commission got its reconciliation. Truth commissions are one of the most popular mechanisms used to foster reconciliation in the aftermath of violent conflict (Hauss 2003, Borer 2006, Daly and Sarkin 2007, Moon 2008). It is increasingly accepted that for peace to be sustained, a culture of reconciliation must be promoted (Lederach 1997, Montville 2006, Volkan 2006, Daly and Sarkin 2007). To assess the contribution made by truth commissions to reconciliation is thus critical. However, such an assessment is currently stalled by an impasse in the literature, which finds determining reconciliation’s meaning complex and operationalising conceptions of reconciliation difficult at the empirical or theoretical level (Daly and Sarkin 2007, Borer 2006). This thesis offers no argument on the general claim that truth commissions reconcile. Instead, explains the insertion of reconciliation within the truth commission model in order to increase future truth commissions’ potential for reconciliation. This thesis argues that South Africa was the first truth commission to be perceived as reconciliation centric. This, it argues, was the result of two things. First, that a politically aware ANC used the word ‘reconciliation’ to ameliorate feelings of injustice regarding the Commission’s amnesty provision and fears of the Commission revealing a painful or dangerous truth. Although its legislators did not intend it to promote reconciliation, the language of the Commission’s founding Act was thus softened with a clause instructing that its tasks be carried out with the overarching aim of promoting reconciliation. Second, the Commission was given to Archbishop Desmond Tutu to run. Tutu used his position as Chair of the Commission to propagate his understanding of the Commission’s role: to promote reconciliation. This thesis concludes that a Commission not designed to promote reconciliation is not as well suited to promoting reconciliation as one that was.

description: Topological band theory has revolutionized our understanding of electronic structure of materials, in particular, a novel state - Weyl semimetal - has been predicted for systems with strong spin-orbit coupling (SOC). Here, a new class of Weyl semimetals, solely made of light elements with negligible SOC, is proposed. Our first-principles calculations show that conjugated p orbital interactions in a three-dimensional pure carbon network, termed interpenetrated graphene network, is sufficient to produce the same Weyl physics. This carbon allotrope has an exceptionally good structural stability. Its Fermi surface consists of two symmetry-protected Weyl loops with linear dispersion along perpendicular directions. Upon the breaking of inversion symmetry, each Weyl loop is reduced to a pair of Weyl points. The surface band of the network is nearly flat with a very large density of states at the Fermi level. It is reduced to Fermi arcs upon the symmetry breaking, as expected.

description: Abstract: Women’s drinking patterns in relation to reproductive health and the parental role have been the subject of considerable research, often focused on the potentially detrimental consequences of alcohol on foetal and infant development (Oei, 2020). While numerous studies have investigated the clinical, epidemiological and preventive aspects of alcohol consumption during pregnancy (e.g., Popova et al. 2017; Gomez et al. 2021), relatively less is known about women’s drinking patterns in the early parenting period (EPP), defined as the first five years after childbirth (Liu et al. 2016). While previous reviews have analysed maternal drinking in the early parenthood primarily focusing on special subgroups of consumers or adverse alcohol consumption outcomes (Chapman et al. 2013, Bottorf et al. 2014, Rossow et al 2016, Qiu et al. 2022), this review considers, instead, the variety of drinking styles which can be observed in the wider population of parents. By drawing on the relevant literature, this scoping review aims to explore the effects that socio-demographic and domestic circumstances have on mothers’ drinking, the theoretical approaches used in literature to explain the changes in consumption and the meanings mothers attribute to their drinking. It will include published peer-reviewed empirical studies informed by quantitative and qualitative research designed. The following databases will be searched: Ovid-MEDLINE, Ovid-PsycINFO, CINAHL, EMBASE. Citation tracking will be conducted in Web of Science Citation Index and Google Scholar. Key information from included quantitative studies will be extracted into evidence tables, and a thematic synthesis of results from qualitative papers will be conducted. Results related to each research questions will be presented through a narrative synthesis. Findings will be disseminated in conferences addressed to academic researchers and practitioners, and through the Centre for Care website, to reach academic and non-academic audiences.

description: During courtship, male butterflies of many species produce androconial secretions containing male sex pheromones (MSPs) that communicate species identity and affect female choice. MSPs are thus likely candidates as reproductive barriers, yet their role in speciation remains poorly studied. Although Heliconius butterflies are a model system in speciation, their MSPs have not been investigated from a macroevolutionary perspective. We use GC/MS to characterize male androconial secretions in 33 of the 69 species in the Heliconiini tribe. We found these blends to be species-specific, consistent with a role in reproductive isolation. We detected a burst in blend diversification rate at the most speciose genus, Heliconius; a consequence of Heliconius and Eueides species using a fatty acid (FA) metabolic pathway to unlock more complex blends than basal Heliconiini species, whose secretions are dominated by plant-like metabolites. A comparison of 10 sister species pairs demonstrates a striking positive correlation between blend dissimilarity and range overlap, consistent with character displacement or reinforcement in sympatry. These results demonstrate for the first time that MSP diversification can promote reproductive isolation across this group of butterflies, showcasing how implementation of an ancestral trait, the co-option of the FA metabolic pathway for pheromone production, can facilitate rapid speciation.
A self-injected, diode-pumped, solid-state ring laser for laser cooling of Li atoms

description: We have constructed a solid-state light source for experiments with laser cooled lithium atoms based on a Nd:YVO$_4$ ring laser with second-harmonic generation. Unidirectional lasing, an improved mode selection, and a high output power of the ring laser was achieved by weak coupling to an external cavity which contained the lossy elements required for single frequency operation. Continuous frequency tuning is accomplished by controlling two PZTs in the internal and the external cavities simultaneously. The light source has been utilized to trap and cool fermionic lithium atoms into the quantum degenerate regime.

description: Laser-induced alignment of particles and molecules was long envisioned to support three-dimensional structure determination using "single-molecule diffraction" with x-ray free-electron lasers [PRL 92, 198102 (2004)]. However, the alignment of isolated macromolecules has not yet been demonstrated, also because quantitative modeling is very expensive. We computationally demonstrated that the alignment of nanorods and proteins is possible with standard laser technology. We performed a comprehensive analysis on the dependence of the degree of alignment on molecular properties and experimental details, e.g., particle temperature and laser-pulse energy. Considering the polarizability anisotropy of about 150,000 proteins, our analysis revealed that most of these proteins can be aligned using realistic experimental parameters.
A self-consistent, absolute isochronal age scale for young moving groups in the solar neighbourhood

description: We present a self-consistent, absolute isochronal age scale for young (< 200 Myr), nearby (< 100 pc) moving groups in the solar neighbourhood based on homogeneous fitting of semi-empirical pre-main-sequence model isochrones using the tau^2 maximum-likelihood fitting statistic of Naylor & Jeffries in the M_V, V-J colour-magnitude diagram. The final adopted ages for the groups are: 149+51-19 Myr for the AB Dor moving group, 24+/-3 Myr for the β Pic moving group (BPMG), 45+11-7 Myr for the Carina association, 42+6-4 Myr for the Columba association, 11+/-3 Myr for the η Cha cluster, 45+/-4 Myr for the Tucana-Horologium moving group (Tuc-Hor), 10+/-3 Myr for the TW Hya association, and 22+4-3 Myr for the 32 Ori group. At this stage we are uncomfortable assigning a final, unambiguous age to the Argus association as our membership list for the association appears to suffer from a high level of contamination, and therefore it remains unclear whether these stars represent a single population of coeval stars. Our isochronal ages for both the BPMG and Tuc-Hor are consistent with recent lithium depletion boundary (LDB) ages, which unlike isochronal ages, are relatively insensitive to the choice of low-mass evolutionary models. This consistency between the isochronal and LDB ages instills confidence that our self-consistent, absolute age scale for young, nearby moving groups is robust, and hence we suggest that these ages be adopted for future studies of these groups.
