description: We investigate the potentiality of using strong lensing clusters to constrain the cosmological parameters Omega_m and Omega_lambda. The existence of a multiple image system with known redshift allows, for a given (Omega_m, Omega_lambda) cosmology, absolute calibration of the total mass deduced from lens modelling. Recent Hubble Space Telescope (HST) observations of galaxy clusters reveal a large number of multiple images, which are predicted to be at different redshifts. If it is possible to measure spectroscopically the redshifts of many multiple images then one can in principle constrain (Omega_m,Omega_lambda) through ratios of angular diameter distances, independently of any external assumptions. For a regular/relaxed cluster observed by HST with 3 multiple image systems, each with different spectroscopic redshifts, we show by analytic calculation that the following uncertainties can be expected: Omega_m=0.30 +/- 0.11, Omega_lambda=0.70 +/- 0.23 or Omega_m=1.00 +/- 0.17, Omega_lambda=0.00 +/- 0.48 for the two most popular world models. Numerical tests on simulated data confirm these good constraints, even in the case of more realistic cluster potentials, such as bimodal clusters, or when including perturbations by galaxies. To investigate the sensitivity of the method to different mass profiles, we also use an analytic ``pseudo-elliptical'' Navarro, Frenk & White profile in the simulations. These constraints can be improved if more than 3 multiple images with spectroscopic redshifts are observed, or by combining the results from different clusters. Some prospects on the determination of the cosmological parameters with gravitational lensing are given.

description: Chest X-ray radiography is one of the earliest medical imaging technologies and remains one of the most widely-used for diagnosis, screening, and treatment follow up of diseases related to lungs and heart. The literature in this field of research reports many interesting studies dealing with the challenging tasks of bone suppression and organ segmentation but performed separately, limiting any learning that comes with the consolidation of parameters that could optimize both processes. This study, and for the first time, introduces a multitask deep learning model that generates simultaneously the bone-suppressed image and the organ-segmented image, enhancing the accuracy of tasks, minimizing the number of parameters needed by the model and optimizing the processing time, all by exploiting the interplay between the network parameters to benefit the performance of both tasks. The architectural design of this model, which relies on a conditional generative adversarial network, reveals the process on how the well-established pix2pix network (image-to-image network) is modified to fit the need for multitasking and extending it to the new image-to-images architecture. The developed source code of this multitask model is shared publicly on Github as the first attempt for providing the two-task pix2pix extension, a supervised/paired/aligned/registered image-to-images translation which would be useful in many multitask applications. Dilated convolutions are also used to improve the results through a more effective receptive field assessment. The comparison with state-of-the-art algorithms along with ablation study and a demonstration video are provided to evaluate efficacy and gauge the merits of the proposed approach.

Subjects: subject: anterior cruciate ligament rupture
subject: lower limb injury prevention
subject: women's sport
subject: football

description: Lower limb injuries are endemic in women’s football and are typically characterised by high rates of recurrence. Anterior cruciate ligament (ACL) ruptures are particularly problematic in women and occur 3-6 times more frequently than in men’s competitions. An evidence-based approach to injury prevention requires identifying the problem, determining the cause(s), introducing a preventative measure, and assessing the effectiveness of the intervention. To date, injury prevention research that is specific to footballers in women’s competitions has been limited. Some of the most significant gaps in evidence are understanding the factors that increase lower limb injury risk in elite women’s football and establishing approaches to mitigating injury risk. Thesis aims: The general aim was to address gaps in the process of developing evidence-based injury prevention strategies specific to women’s players for the most common (hip/groin and hamstring strain injuries) and severe (ACL ruptures) lower limb injuries in football. Specific chapter aims were to: 1) systematically review evidence for intrinsic lower limb injury risk factors in women, 2) compare strength and biomechanics between elite women footballers with and without prior lower limb injury, 3) establish lower limb strength and biomechanical risk factors for ACL injury in elite women’s football, and 4) characterise gluteal muscle forces during a range of hip exercises in women to inform exercise selection for ACL injury prevention programmes (i.e. on the basis that these muscles are important for “unloading” the ACL during dynamic tasks).
Teleology in biology, chemistry and physics education: what primary teachers should know

description: Recent research in cognitive psychology suggests that children develop intuitions that may clash with what is accepted by scientists, thus making certain scientific concepts difficult to understand. Children possess intuitions about design and purpose that make them provide teleological explanations to many different sorts of tasks. One possible explanation for the origin of the bias to view objects as made for something derives from an early sensitivity to intentional agents and to their behavior as intentional object users and object makers. What is important is that teleological explanations may not be exclusively restricted in biological phenomena, as commonly assumed. Consequently, primary school teachers should take that into account when teaching biology, chemistry or physics concepts and try to refrain from enforcing students’ teleological intuitions

description: We study quadrature rules for functions from an RKHS, using nodes sampled from a determinantal point process (DPP). DPPs are parametrized by a kernel, and we use a truncated and saturated version of the RKHS kernel. This link between the two kernels, along with DPP machinery, leads to relatively tight bounds on the quadrature error, that depends on the spectrum of the RKHS kernel. Finally, we experimentally compare DPPs to existing kernel-based quadratures such as herding, Bayesian quadrature, or leverage score sampling. Numerical results confirm the interest of DPPs, and even suggest faster rates than our bounds in particular cases.

description: The paper presents the results of the evaluation of a university environmental course on pre-service teachers’ conceptions of environmental issues and environmental education. The evaluation method leaned on the theory of social representations and used stimulus terms to trigger respondents’ ideas. The course had a positive effect on participants’ conceptions, as it was indicated by the transformation of the conceptual framework for the stimulus terms. Our findings offered valuable insights for the proper transformation of the course while the easiness of the applied method in data collection, renders feasible the longitudinal monitoring of course effects.

description: We present Chandra X-ray Observatory imaging observations of the young Galactic supernova remnant G11.2-0.3. The image shows that the previously known young 65-ms X-ray pulsar is at position (J2000) RA 18h 11m 29.22s, DEC -19o 25' 27.''6, with 1 sigma error radius 0.''6. This is within 8'' of the geometric center of the shell. This provides strong confirming evidence that the system is younger, by a factor of ~12, than the characteristic age of the pulsar. The age discrepancy suggests that pulsar characteristic ages can be poor age estimators for young pulsars. Assuming conventional spin down with constant magnetic field and braking index, the most likely explanation for the age discrepancy in G11.2-0.3 is that the pulsar was born with a spin period of ~62 ms. The Chandra image also reveals, for the first time, the morphology of the pulsar wind nebula. The elongated hard-X-ray structure can be interpreted as either a jet or a Crab-like torus seen edge on. This adds to the growing list of highly aspherical pulsar wind nebulae and argues that such structures are common around young pulsars.

Subjects: subject: Criminal justice

subject: International securitization

description: This is a narrative about the way in which a category of crime-to-be-combated is constructed through the discipline of criminology and the agents of discipline in criminal justice. The aim was to examine organized crime through the eyes of those whose job it is to fight it (and define it), and in doing so investigate the ways social problems surface as sites for state intervention. A genealogy of organized crime within criminological thought was completed, demonstrating that there are a range of different ways organized crime has been constructed within the social scientific discipline, and each of these were influenced by the social context, political winds and intellectual climate of the time. Following this first finding, in-depth qualitative interviews were conducted with individuals who had worked at the apex of the policing of organized crime in Australia, in order to trace their understandings of organized crime across recent history. It was found that organized crime can be understood as an object of the discourse of the politics of law and order, the discourse of international securitization, new public management in policing business, and involves the forging of outlaw identities. Therefore, there are multiple meanings of organized crime that have arisen from an interconnected set of social, political, moral and bureaucratic discourses. The institutional response to organized crime, including law and policing, was subsequently examined. An extensive legislative framework has been enacted at multiple jurisdictional levels, and the problem of organized crime was found to be deserving of unique institutional powers and configurations to deal with it. The social problem of organized crime, as constituted by the discourses mapped out in this research, has led to a new generation of increasingly preemptive and punitive laws, and the creation of new state agencies with amplified powers. That is, the response to organized crime, with a focus on criminalization and enforcement, has been driven and shaped by the four discourses and the way in which the phenomenon is constructed within them. An appreciation of the nexus between the emergence of the social problem, and the formation of institutions in response to it, is important in developing a more complete understanding of the various dimensions of organized crime.
Rethinking what is "developmentally appropriate" from a learning progression perspective: The power and the challenge

description: Learning progressions have recently become increasingly visible in studies of learning and instruction in science. In this essay, I explore the power and considerable challenges in rethinking what may be developmentally appropriate for young children's learning science from the perspective of learning progressions. In particular, I examine the issues of: a) the design of promising learning progressions within the vast design space of potential progressions; b) identification of cognitive resources relevant to a progression; c) analysis of effort / payoff for particular competencies at different points in the progression; d) attribution of cognitive limitations and achievements; e) coordination and collaboration needed to support the design, utilization, and refinement of the learning progression; and f) absence of straightforward correspondence between a learning progression and trajectories of different children's knowledge-development.

description: The structure of the excited $2^{3}$S and $2^{3}$P triplet states of $^{3}$He and $^{4}$He in an applied magnetic field B is studied using different approximations of the atomic Hamiltonian. All optical transitions (line positions and intensities) of the 1083 nm $2^{3}$S-$2^{3}$P transition are computed as a function of B. The effect of metastability exchange collisions between atoms in the ground state and in the $2^{3}$S metastable state is studied, and rate equations are derived, for the populations these states in the general case of an isotopic mixture in an arbitrary field B. It is shown that the usual spin-temperature description remains valid. A simple optical pumping model based on these rate equations is used to study the B-dependence of the population couplings which result from the exchange collisions. Simple spectroscopy measurements are performed using a single-frequency laser diode on the 1083 nm transition. The accuracy of frequency scans and of measurements of transition intensities is studied. Systematic experimental verifications are made for B=0 to 1.5 T. Optical pumping effects resulting from hyperfine decoupling in high field are observed to be in good agreement with the predictions of the simple model. Based on adequately chosen absorption measurements at 1083 nm, a general optical method to measure the nuclear polarisation of the atoms in the ground state in an arbitrary field is described. It is demonstrated at $B\sim$0.1 T, a field for which the usual optical methods could not operate.

description: Background So far only single cases with short follow-up have been reported on the use of intravitreal anti-VEGF for traumatic choroidal neovascularizations (CNV). This paper reports a large case series of patients with CNV secondary to choroidal rupture after ocular trauma receiving intravitreal anti-VEGF (vascular endothelial growth factor) injections. Methods Fifty-four patients with unilateral choroidal rupture after ocular trauma diagnosed between 2000 and 2016 were retrospectively evaluated. Eleven patients with CNV secondary to choroidal rupture were identified. Five eyes with traumatic secondary CNV were treated with anti-VEGF and were systematically analysed. The other 4 patients with inactive CNV underwent watchful observation. Results Four men and one woman with a mean age of 29 years (SD 12.4; range 19–45) had intravitreal anti-VEGF therapy for traumatic CNV. Another 4 patients with a mean age of 37 years (SD 6.6; range 31–46) presented with inactive CNV and did not receive specific treatment. In all 9 cases the mean interval between the ocular trauma and the diagnosis of CNV was 5.7 months (SD 4.75; range 2–12). In the treatment group per eye 4.2 injections (SD 3.2; range 1–8) were given on average. Four eyes were treated with bevacizumab and one eye with ranibizumab. Regression of CNV was noted in all eyes. In 4 eyes visual acuity (VA) improved, one eye kept stable visual acuity. Conclusions Here, we present the up to now largest case series of traumatic CNV membranes treated with anti-VEGF injections with a mean follow-up period of 5 years. Intravitreal anti-VEGF therapy seems to be safe and effective for secondary CNV after choroidal rupture. Compared to exudative age-related macular degeneration fewer injections are needed to control the disease. Trial registration Retrospective registration with local ethics committee on 21 March 2019.

description: Community identification of network components enables us to understand the mesoscale clustering structure of networks. A number of algorithms have been developed to determine the most likely community structures in networks. Such a probabilistic or stochastic nature of this problem can naturally involve the ambiguity in resultant community structures. More specifically, stochastic algorithms can result in different community structures for each realization in principle. In this study, instead of trying to "solve" this community degeneracy problem, we turn the tables by taking the degeneracy as a chance to quantify how strong companionship each node has with other nodes. For that purpose, we define the concept of companionship inconsistency that indicates how inconsistently a node is identified as a member of a community regarding the other nodes. Analyzing model and real networks, we show that companionship inconsistency discloses unique characteristics of nodes, thus we suggest it as a new type of node centrality. In social networks, for example, companionship inconsistency can classify outsider nodes without firm community membership and promiscuous nodes with multiple connections to several communities. In infrastructure networks such as power grids, it can diagnose how the connection structure is evenly balanced in terms of power transmission. Companionship inconsistency, therefore, abstracts individual nodes' intrinsic property on its relationship to a higher-order organization of the network.

Engagement in science, engineering and technology in the early years: A cultural-historical reading

description: This paper seeks answers to the question “what engages young children in science, engineering and technology (SET)?”. A review of the SET literature is undertaken to find out what are the dominant themes noted in the research literature for engaging young children in SET. Two kinds of analyses are presented in this paper. The first analysis draws upon developmental theory because it is still the dominant worldview within early childhood education, and is closely aligned with constructivism, the major theory within SET education research. This analysis gives some insights into the concept of engagement from a developmental perspective. However, many of the findings identified in the studies reviewed could not easily fit within a traditional developmental framework. A second analysis was undertaken, using cultural-historical theory. It was found that engagement could be explained more fully when it was theorised in relation to Vygotsky’s (1987) and Leont’ev’s (1978) concept of “motives” in the context of Kravtsova’s (2008) concept of the “zone of potential development”. This latter theorisation allowed for a richer discussion of SET engagement for early childhood education. The paper concludes with a model of SET engagement for early childhood education.

Thermality of the Rindler horizon: A simple derivation from the structure of the inertial propagator

description: The Feynman propagator encodes all the physics contained in a free field and transforms as a covariant bi-scalar. Therefore, we should be able to discover the thermality of the Rindler horizon, just by probing the structure of the propagator, expressed in the Rindler coordinates. I show that the thermal nature of the Rindler horizon is indeed contained --- though hidden --- in the standard, inertial, Feynman propagator. The probability $P(E)$ for a particle to propagate between two events, with energy $E$, can be related to the temporal Fourier transform of the propagator. A strikingly simple computation reveals that: (i) $P(E)$ is equal to $P(-E)$ if the propagation is between two events in the same Rindler wedge while (ii) they are related by a Boltzmann factor with temperature $T=g/2π$, if the two events are separated by a horizon. A more detailed computation reveals that the propagator itself can be expressed as a sum of two terms, governing absorption and emission, weighted correctly by the factors $(1+n_ν)$ and $n_ν$ where $n_ν$ is a Planck distribution at the temperature $T=g/2π$. In fact, one can discover the Rindler vacuum and the alternative (Rindler) quantization, just by probing the structure of the inertial propagator. These results can be extended to local Rindler horizons around any event in a curved spacetime. The implications are discussed.

description: We have studied the Globular Cluster System of the merger galaxy NGC 1316 in Fornax, using CCD BVI photometry. A clear bimodality is not detected from the broadband colours. However, dividing the sample into red (presumably metal- rich) and blue (metal-poor) subpopulations at B-I=1.75, we find that they follow strikingly different angular distributions. The red clusters show a strong correlation with the galaxy elongation, but the blue ones are circularly distributed. No systematic difference is seen in their radial profile and both are equally concentrated. We derive an astonishingly low Specific Frequency for NGC 1316 of only Sn=0.9, which confirms with a larger field a previous finding by Grillmair et al. (1999). Assuming a "normal" Sn of ~4 for early-type galaxies, we use stellar population synthesis models to estimate in 2 Gyr the age of this galaxy, if an intermediate-age population were to explain the low Sn we observe. This value agrees with the luminosity-weighted mean age of NGC 1316 derived by Kuntschner & Davies (1998) and Mackie & Fabbiano (1998). By fitting t5 functions to the Globular Cluster Luminosity Function (GCLF), we derived the following turnover magnitudes: B=24.69 +/- 0.15, V=23.87 +/- 0.20 and I=22.72 +/- 0.14. They confirm that NGC 1316, in spite of its outlying location, is at the same distance as the core of the Fornax cluster.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Transversals, duality, and irrational rotation

description: An early result of Noncommutative Geometry was Connes' observation in the 1980's that the Dirac-Dolbeault cycle for the $2$-torus $\mathbb{T}^2$, which induces a Poincaré self-duality for $\mathbb{T}^2$, can be 'quantized' to give a spectral triple and a K-homology class in $KK_0(A_θ\otimes A_θ, \mathbb{C})$ providing the co-unit for a Poincaré self-duality for the irrational rotation algebra $A_θ$ for any $θ\in \mathbb{R}\setminus \mathbb{Q}$. This spectral triple has been extensively studied since. Connes' proof, however, relied on a K-theory computation and does not supply a representative cycle for the unit of this duality. Since such representatives are vital in applications of duality, we supply such a cycle in unbounded form in this article. Our approach is to construct, for any non-trivial element $g$ of the modular group, a finitely generated projective module $\mathcal{L}_g$ over $A_θ\otimes A_θ$ by using a reduction-to-a-transversal argument of Muhly, Renault, and Williams, applied to a pair of Kronecker foliations along lines of slope $θ$ and $g(θ)$, using the fact that these flows are transverse to each other. We then compute Connes' dual of $[\mathcal{L}_g]$ for $g$ upper triangular, and prove that we obtain an invertible in $KK_0(A_θ, A_θ)$, represented by what one might regard as a noncommutative bundle of Dirac-Schrödinger operators. An application of $\mathbb{Z}$-equivariant Bott Periodicity proves that twisting the module by the family gives the requisite spectral cycle for the unit, thus proving self-duality for $A_θ$ with both unit and co-unit represented by spectral cycles.

title: Sounding the Horn: Examining the Live Performance Practices of Australian Classical Saxophonists
Creators: name: Di Marco, Emma Lucy

Subjects: subject: Classcal saxophone music
subject: Western art music
subject: Saxophone performance

description: Classical saxophone music (or CSM) is understood as Western art music, composed for the saxophone, which includes a variety of global influences and has developed since the invention of the instrument in the 1840’s. In Australia, a number of entrepreneurial musicians are specialising in this unique genre and showcasing new Australian music in a variety of live performance situations. Further to this, understanding exactly what knowledge and skills currently required by young classical musicians to build successful and sustainable careers is a strong industry focus. With the increasing need for entrepreneurial mindsets to be adopted and the acceptance of the portfolio career model as common practice for classical musicians, early career performing musicians need to develop a multi-dimensional approach to their future careers. Responding to these current realities, this thesis explores the live performance activities of Australia’s leading classical saxophonists and through four key areas: Logistical Considerations, Artistic Relationships, Digital Engagement, and Performer Satisfaction. In order to address these four areas, the thesis presents nine case studies of leading Australian classical saxophonists and saxophone ensembles; showing insights into how they navigate modern challenges in the industry. Drawing on research in a variety of fields including portfolio career models, the integration of technology into live performances, and the everyday management of live performance activities, the thesis presents the conclusions which are most pertinent to musicians actively striving to build a performance based career in the current industry.

description: The present work shows the construction that preschool students can make about conceptions of color, light, formation of shadows and images in a plane mirror, with the application of a didactic proposal (EduCienPre) in which didactic sequences and materials are developed and which can be introduced to a classroom under normal conditions. The characteristics of the didactic proposal are described and preschoolers conceptual constructions are analyzed as a function of their explanations and representations. Analysis of children’s actions in diverse physical situations offers deeper elements for understanding the construction of representations and scientific notions which could be reflected in a more adequate teaching of the sciences for small children.

Analysing young children’s thinking about natural phenomena: A sociocultural/cultural historical perspective
Creators: name: ROBBINS, JILL
Publisher: name: Review of Science, Mathematics and ICT Education
Year: 2012
Subjects: Young children’s thinking, sociocultural/cultural-historical theory, methodology, early childhood science

description: Vygotsky’s sociocultural/cultural historical theory emphasised the notion of semiotic mediation – or how thinking is transformed through signs (such as language) and cultural tools (such as drawings) from an intermental to an intramental plane. While the ideas of Vygotsky have become well-accepted within research in early childhood education in Australia, they are somewhat slower to be adopted within science education research. Yet they offer the potential for gaining new understandings of how young children’s thinking about the world develops. This article will demonstrate one way in which aspects of Vygotsky’s (1987-1999) work, particularly his ideas about semiotic mediation can inform analysis of children’s thinking about the world. Focusing on conversations with children about natural phenomena, and drawings they completed during those conversations, the analysis identifies a number of significant issues that are not normally revealed within the dominant forms of analysis which draw on constructivist perspectives. The findings, which reveal complex and dynamic aspects of children’s thinking, have implications for both teachers and researchers working with young children – especially within science education and science education research.

subject: Behavioural issues in drug use

description: Injecting drug use worldwide accounts for a high proportion of new Human Immunodeficiency Virus (HIV) infection, driving the national epidemics in many countries where HIV prevalence among injecting drug users (IDUs) is prominent. HIV testing started in Vietnam in 1988 and the first HIV case was detected in 1990. The epidemic has now concentrated among young IDUs in northern Vietnam. Hai Phong is one of the provinces located in the north of Vietnam which has become a high HIV prevalence province affecting young IDUs. The present research estimates HIV infection rates among IDUs in Hai Phong. It examines behavioural risk factors associated with HIV infection, sharing and condom use as well as highlighting drug and sex related transmission risks. The research has several stages including secondary analysis of national level behavioural survey data (2011) and qualitative exploratory research (2012). Each phase of the research supplements the others, in order to attain the research objectives and to address behavioural issues associated with the current epidemic.
