Subjects: Socio-cultural, historical approach, preschoolers’ interactions, explanatory schemes, conversational approach, science thinking and learning in early childhood

description: In this research paper, the dynamic of preschoolers’ interactions during the approach of basic science concepts in kindergarten is designated, based on the “socio-cultural, historical approach”. The procedures through which young children communicate and cooperate in order to structure their explanatory schemes and the contextual factors that mediate in this process are explored through a multilayer qualitative analysis. The research sample consisted of sixteen (16) pre-school children (four to six years old) from one state kindergarten in Greece. Data were collected through expanded, open type, semi-structured conversations between children pairs of the sample and one of the researchers. In this paper, data from three (3) conversations in which six (6) children participated in pairs are presented. The results of the study indicated different types of substantial interactions between the children couples and led to the detection of ways that preschooler’s conceptions shaped and were shaped while concepts from the natural world were commonly approached. From the research results, can be concluded that through a “conversational approach”, organized in couples, we can foster and enhance science thinking and learning in early childhood.

description: The testing of the scheme inspired and designed from the nomenclature introduced by J.-L. Dessalles relating to notions of 'thematic segmentation', 'representation scenic' proximal function of language 'and' cognitive conflict 'states existence for knowledge covered by the education systems of science and technology, a relationship of cause and effect between the absence of the topic segmentation on this knowledge in the discourse of the noosphere and Development in the vast majority of students of high mathematical content courses and physics, stage performances offset whatsoever to update these knowledge. This discrepancy could be aggravated by the fact that the school of tomorrow is the spatiotemporal variables as control variables in the hands of the teacher. The latter is brought so to articulate his speech around an optimal mobilization of these variables and, based, inter alia, the schema structuring teacher discourse: The knowledge will not stay too long in a static form; the kinesthetic sense of place as an example trapezium and strong argument, become a teaching subject in itself.

description: This paper has made some significant advances in the boundary-only and domain-type RBF techniques. The proposed boundary knot method (BKM) is different from the standard boundary element method in a number of important aspects. Namely, it is truly meshless, exponential convergence, integration-free (of course, no singular integration), boundary-only for general problems, and leads to symmetric matrix under certain conditions (able to be extended to general cases after further modified). The BKM also avoids the artificial boundary in the method of fundamental solution. An amazing finding is that the BKM can formulate linear modeling equations for nonlinear partial differential systems with linear boundary conditions. This merit makes it circumvent all perplexing issues in the iteration solution of nonlinear equations. On the other hand, by analogy with Green's second identity, we also presents a general solution RBF (GSR) methodology to construct efficient RBFs in the domain-type RBF collocation method and dual reciprocity method. The GSR approach first establishes an explicit relationship between the BEM and RBF itself on the ground of the potential theory. This paper also discusses some essential issues relating to the RBF computing, which include time-space RBFs, direct and indirect RBF schemes, finite RBF method, and the application of multipole and wavelet to the RBF solution of the PDEs.

description: Information structure describes the way in which information is organized in a discourse to serve the purpose of communication. A core part of information structure is focus, whose main function is to indicate new information or the information that updates the common ground. In a question (e.g., 'What did the captain put on?'), the focus is the unknown information asked about by the wh-phrase. Prosody (prosodic prominence) and syntax (syntactic clefting) can be used to signal focus in Mandarin. However, the relative importance of these cues has not been established in speech perception. This study probes listeners' judgements on the appropriateness of an answer to a question in Mandarin. Results show that prosodic prominence appears to be more effective than syntactic clefting as a cue for listeners to perceive where the focus is. Syntax plays an inhibitory rather than facilitatory role. This research provides the first evidence of the interaction of syntax and prosody in the perception of focus in Mandarin, and contributes to a growing body of research showing cross-linguistic differences in the weighting of prosodic and syntactic cues in the perception of focus.

description: This paper questions the joint work of a scientific instructor, a teacher and her grade four students, when they visit a science festival out of school. The theoretical frame draws on Joint Action Theory of Didactics and the study aims to describe the connections between the actions of the different subjects. In this paper we focus on methodological tools, which aim is to make visible didactic transactions. We introduce for this purpose “synoptic representations” and expose how they can account for the time and space organisation of the co-intervention.

description: Lead halide perovskites are causing a change of paradigm in photovoltaics. Among other peculiarities, these perovskites exhibit an atypical temperature dependence of the fundamental optical gap: It decreases in energy with decreasing temperature. So far reports ascribe such a behavior to a particularly strong electron-phonon renormalization of the band gap, neglecting completely contributions from thermal expansion effects. However, high pressure experiments performed, for instance, on the archetypal perovskite MAPbI$_3$, where MA stands for methylammonium, yield a negative pressure coefficient for the gap of the tetragonal room-temperature phase, which speaks against the assumption of a negligible gap shift due to thermal expansion. On the basis of the high pressure results, we show here that for MAPbI$_3$ the temperature-induced gap renormalization due to electron-phonon interaction can only account for about 40\% of the total energy shift, thus implying thermal expansion to be the dominant term. Furthermore, this result possesses general validity, holding also for the tetragonal or cubic phase, stable at ambient conditions, of other halide perovskite counterparts.

description: The responsible management and reduction of carbon dioxide (CO2) emissions to the atmosphere requires consideration of alternative options for disposal and long-term sequestration of CO2 generated at hydrocarbon-fueled power plants and large industrial sources. A number of “conventional” options for geological sequestration of CO2 are currently being evaluated worldwide, including disposal of CO2 in depleted oil and gas reservoirs, in deep saline aquifers, and in unrecoverable coal beds, typically in gaseous or liquid form or as a supercritical fluid. Although these geological settings may constitute the most readily accessible sites for immediate utilization, it is unlikely that they represent sufficient cumulative storage capacity to keep pace with global CO2 production and future disposal requirements. In addition, the requirement for long-term maintenance of CO2 sequestered in fluid form, raises concerns regarding the possible mobility of disposed CO2 over the longer term. The Geological Survey of Canada (GSC) has investigated potential opportunities to sequester CO2 in solid form in Canadian geologic reservoirs having pressure and temperature conditions suitable for the formation and long-term stability of CO2 hydrate. Initial screening of candidate reservoirs has identified substantial potentials for CO2 sequestration as gas hydrate in extensive porous sandstone and limestone formations beneath portions of the Canadian Great Lakes, and in areas of the Mackenzie-Beaufort hydrocarbon development region in northern Canada. A significant but less robust capacity has been identified in the oil and gas production regions of northeastern Alberta.

subject: Public opinion polls

description: The study of public opinion has become increasingly central to our understanding of American politics. What the American public believes, why it holds those beliefs, and whether or not those beliefs matter have become essential questions that guide our understanding of how American democracy functions. In order to answer these questions, however, it is important to consider the tools we use to measure public opinion accurately and reliably and to understand the substantive applications and limitations of those tools. This dissertation is composed of three essays that consider important questions in public opinion measurement today. The first considers how the technique of multilevel regression with poststratification (MRP) performs on polling data collected using area-based cluster sampling techniques. While MRP has been a boon to researchers with limited resources, it must still be examined to understand its strengths and shortcomings. The second paper uses two datasets to look at the measurement of scales of political values over time, focusing on both individual and state-level measures, and discusses implications of these results for larger debates around the measurement of partisan sorting and polarization. The third paper turns to the question of social desirability bias in polling. Specifically, it uses list experiments to look at whether survey respondents answer truthfully when asked about support for same-sex rights. These papers all aim to shed light on recent innovations in the measurement of public opinion and illustrate how we can use these innovations to improve our understanding of American public opinion.

description: The situation of technical teaching in Morocco shows that there are shortcomings which seem to persist despite the reforms the Moroccan educational system has undergone. It is no longer about describing this teaching's current situations, but it is, above all, about finding a remedy to them by admitting that the linguistic problems the students encounter deprive them from persevering in the technical domain. The survey we have conducted within the Electric Engineering Branch at L'École Supérieure de Technologie (College of Technology) in Agadir has allowed us to detect the causes that strongly relate to the French language and the teaching of scientific subjects in secondary schools. Analyzing the direct consequences on the students learning process will allow us to handle the problem correctly and suggest some solutions.

description: Polynomial sequences $p_n(x)$ of binomial type are a principal tool in the umbral calculus of enumerative combinatorics. We express $p_n(x)$ as a \emph{path integral} in the ``phase space'' $\Space{N}{} \times {[-π,π]}$. The Hamiltonian is $h(ϕ)=\sum_{n=0}^\infty p_n'(0)/n! e^{inϕ}$ and it produces a Schrödinger type equation for $p_n(x)$. This establishes a bridge between enumerative combinatorics and quantum field theory. It also provides an algorithm for parallel quantum computations. Keywords: Feynman path integral, umbral calculus, polynomial sequence of binomial type, token, Schrödinger equation, propagator, wave function, cumulants, quantum computation.

Rapid Stabilization of Droplets by Particles in Microfluidics: Role of Droplet Formation

description: Droplet-based microfluidics has emerged as a powerful technology for the miniaturization and automation of biochemical assays. The replacement of surfactants by nanoparticles as interfacial stabilizers has gained increasing interest. However, the stabilization mechanism of droplets by nanoparticles in microchannels is poorly understood, drastically hindering the development of practical applications. Current methods for droplet stabilization involve a trade-off between low droplet production throughput and waste of large number of nanoparticles. Here, we introduce a modification to the droplet production junction that reduces the droplet stabilization time by an order of magnitude, and at the same time significantly reduces the particle waste. Our results show that the limiting step in the kinetics of stabilization is the initial time where both phases come into contact and offer a guideline for the design of particle-stabilized droplet production devices.

description: Gas hydrate has been identified by drilling in Alaminos Canyon block 818, within the Perdido Fold Belt, outboard of the Sigsbee Escarpment, in approximately 2750 meters (9000 feet) of water. At the location of the AC818 #1 (“Tigershark”) well, the gas hydrate occurs within the top 20 m (65 feet) of an approximately 90 meter (300 feet) thick Oligocene Frio sand, a volcaniclastic sandstone rich in lithic fragments, feldspar, and volcanic ash. The Frio reservoir is folded into a 4-way closed anticline. At the crest of the anticline, the sand is partly eroded and is unconformably overlain by 450 m (1500 feet) of Pleistocene shale and sand. The unconformity surface is also in a 4-way closed geometry and defines the top of the hydrate reservoir at the well. The rock is poorly consolidated and has porosity as high as 42% from log data. LWD logs indicate that the hydrate zone has high resistivity and high P-velocity (2750 mps: 9000 fps). The underlying wet sand at the base of the gas hydrate stability zone (GHSZ) has low resistivity and P-velocity (Vp: 1500 mps: 5000 fps). The very low Vp indicates the presence of low-saturation free gas ("fizz gas"). The large velocity contrast creates a strong response in seismic data which was inverted into a 3D gas hydrates saturation (Sgh) volume. Elsewhere in the GHSZ, seismic character was used to predict predominant sediment facies. Relative high stand facies, which are more clay-rich, will generally be characterized by more continuous and parallel seismic reflectors. In contrast, relative low stand facies, which have more sand content, will be characterized by more hummocky, discontinuous seismic character and will often lie on erosional surfaces, particularly in uncompacted sediments. Understanding the stratigraphy throughout the section is important, since sand will often provide beneficial reservoir conditions, while clay will provide more impervious sealing qualities. The seismic interpretation also identifies migration pathways, such as faults and gas chimneys, and the presence of available gas, which are necessary to charge reservoirs within the HSZ.

description: This paper focuses on two aspects of the statistics of cosmological observables that are important for the next stages of precision cosmology. First, we note that the theory of reduced angular $N$-point spectra has only been developed in detail up to the trispectrum case and in a fashion that makes it difficult to go beyond. To fill this gap, here we present a constructive approach that provides a systematic description of reduced angular $N$-point spectra and their covariance matrices, for arbitrary $N$. Second, we focus on the common practice in the literature on cosmological observables, which consists in simply discarding a part of the expression, namely, the terms containing fields evaluated at the observer position. We point out that this is not justified beyond linear order in perturbation theory, as these terms contribute to all the multipoles of the corresponding spectra and with a magnitude that is of the same order as the rest of the non-linear corrections. We consider the possibility that the reason for neglecting these terms is a conceptual discomfort when using ensemble averages, which originates in an apparent tension between the ergodic hypothesis and the privileged position of the observer on the light-cone. We clarify this subtle issue by performing a careful derivation of the relation between the theoretical statistical predictions and the observational estimators for all $N$. We conclude that there is no inconsistency whatsoever in ensemble-averaging fields at and near the observer position, thus clearing the way for consistent and robust high-precision calculations.

description: Two mixed models exist in analysis of two-way factorial ANOVA with mixed effects and interactions: the constrained and unconstrained models. The constrained model is unfavored because there is no convincing rationale for the enforced constraints on its random interactions and a lack of clear interpretation about its variance components. The purpose of this study is to further explore the relationship between these two models. We reveal some nice features of the constrained model on partition of the responsive variance. An alternative formulation of ANOVA that follows from this exploration is also presented.

description: Within the research community in science education, there has been a tendency to show limited interest in examining PISA results with reference to the national context of participating countries although this approach can give valuable insight into a country’s students’ achievement. Since the interpretations of PISA results could be based on a thorough analysis of the actual items used in international and national contexts, the main issue addressed in this study is to compare PISA test items with assessment tasks used in the Greek school context. 281 PISA science test items as well as 947 assessment tasks included in science school textbooks and 4,248 science examination test items in Greece, were analysed in regard to the frequency of inclusion, the type and the functional role of visual representations within this assessment tasks. The results demonstrate that while PISA test items use visual material in order to communicate scientific information in everyday life contexts by means of specialised graphs and photographs of familiar entities, schooling does not familiarize Greek students with visual representations widely used in science and embedded in real-life situations.

description: In forested headwater streams, ecological processes such as carbon and nutrient cycling, the stream hydrological regime, and the structure of biological assemblages are tightly linked to the surrounding catchment. As such, headwater streams are vulnerable to disturbances within their catchments at various spatial (e.g. reach and catchment) and temporal (e.g. months to decades) scales. Forest harvesting is an example of a disturbance that has been widely linked to changes in the structure and function of biological communities, and changes in stream processes, such as leaf breakdown. This thesis explores the short term (1 year) response of benthic organic matter storage and retention, leaf litter breakdown and macroinvertebrate structural and functional assemblage composition in headwater streams to catchment-scale selective harvesting in dry-sclerophyll forest in north-eastern NSW Australia. This study used a Multiple Before-After Control-Impact (MBACI) design, with five small adjacent equivalent-sized catchments (302-770 ha), three of which were selectively harvested during a commercial forestry operation, with two left as unharvested controls. Riparian vegetation was retained in accordance with licence conditions for Forests NSW. All five streams were gauged, and since 2001 Forests NSW have been collecting data on turbidity, suspended solids, temperature, run off and stream flow. Standing stocks and composition of coarse particulate organic matter (CPOM) were quantified before and after harvesting in all five catchments, with the prediction that stocks would be significantly lower in harvested streams. Mean standing stocks in all five streams were highly variable spatially and temporally, but harvested streams did not differ significantly from control streams in standing stocks of CPOM. Composition of CPOM was consistent across all streams and proportionally dominated by leaves, then small wood and bark. These findings were remarkably similar to values reported from other Australian streams. The results indicate that in the short term (1 year) there were no detectable reductions in CPOM standing stocks or changes in CPOM composition from selective harvesting.

description: We synthesized the 5d1-transition metal oxides AOsO4 (A = K, Rb, Cs) by solid-state reaction, and performed structure determination and magnetic and heat capacity measurements. It was found that they crystallize in a scheelite (A = K and Rb) or a quasi-scheelite structure (A = Cs) comprising of distorted diamond lattices of septivalent Os (d1) ions tetrahedrally coordinated by four oxide ions without local inversion symmetry; hence an antisymmetric spin-orbit coupling is expected in the crystals. The K and Rb compounds have Weiss temperatures of theta = -66 and -18 K, effective magnetic moments of mu_eff = 1.44 and 1.45 mu_B/Os, and antiferromagnetic transition temperatures of T_N = 36.9 and 21.0 K, respectively. In contrast, the Cs compound has theta = 12 K and mu_eff = 0.8 mu_B/Os without magnetic transition above 2 K, instead exhibiting a first-order structural transition at T_s = 152.5 K. The decline of the Os moment from 1.73 mu_B/Os for the simple d1 spin, particularly for Cs, is likely to originate from the antiparallel orbital moment, although the spin-orbit coupling is generally quenched in the low-lying e orbitals.

Anyons and the Bose-Fermi duality in the finite-temperature Thirring model

description: Solutions to the Thirring model are constructed in the framework of algebraic QFT. It is shown that for all positive temperatures there are fermionic solutions only if the coupling constant is $λ=\sqrt{2(2n+1)π}, n\in {\bf N}$. These fermions are inequivalent and only for $n=1$ they are canonical fields. In the general case solutions are anyons. Different anyons (which are uncountably many) live in orthogonal spaces and obey dynamical equations (of the type of Heisenberg's "Urgleichung") characterized by the corresponding values of the statistic parameter. Thus statistic parameter turns out to be related to the coupling constant $λ$ and the whole Hilbert space becomes non-separable with a different "Urgleichung" satisfied in each of its sectors. This feature certainly cannot be seen by any power expansion in $λ$. Moreover, since the latter is tied to the statistic parameter, it is clear that such an expansion is doomed to failure and will never reveal the true structure of the theory. The correlation functions in the temperature state for the canonical dressed fermions are shown by us to coincide with the ones for bare fields, that is in agreement with the uniqueness of the $τ$-KMS state over the CAR algebra ($τ$ being the shift automorphism). Also the $α$-anyon two-point function is evaluated and for scalar field it reproduces the result that is known from the literature.

description: We consider a general construction of ``kicked systems''. Let G be a group of measure preserving transformations of a probability space. Given its one-parameter/cyclic subgroup (the flow), and any sequence of elements (the kicks) we define the kicked dynamics on the space by alternately flowing with given period, then applying a kick. Our main finding is the following stability phenomenon: the kicked system often inherits recurrence properties of the original flow. We present three main examples. 1) G is the torus. We show that for generic linear flows, and any sequence of kicks, the trajectories of the kicked system are uniformly distributed for almost all periods. 2) G is a discrete subgroup of PSL(2,R) acting on the unit tangent bundle of a Riemann surface. The flow is generated by a single element of G, and we take any bounded sequence of elements of G as our kicks. We prove that the kicked system is mixing for all sufficiently large periods if and only if the generator is of infinite order and is not conjugate to its inverse in G. 3) G is the group of Hamiltonian diffeomorphisms of a closed symplectic manifold. We assume that the flow is rapidly growing in the sense of Hofer's norm, and the kicks are bounded. We prove that for a positive proportion of the periods the kicked system inherits a kind of energy conservation law and is thus superrecurrent. We use tools of geometric group theory and symplectic topology.

description: This article retraces the path made ​​by the concept of resonance, through textbooks and ancient books of physics, according to the definitions it was given over a period of nearly a century and a half. Chronology, which also shows the objects that the resonance was interested in the past, seeks to identify conceptual change across different formulations and historical presentations to this concept. We conjecture some mental obstacles overcame in this period. The university teaching of resonance in wave physics could be improved by taking into account these obstacles.

description: We use tropical curves and toric degeneration techniques to construct closed embedded Lagrangian rational homology spheres in a lot of Calabi-Yau threefolds. We apply this construction to the tropical curves obtained from the 2875 lines on the quintic Calabi-Yau threefold. Each admissible tropical curve gives a Lagrangian rational homology sphere in the corresponding mirror quintic threefold and disjoint curves give pairwise homologous but non-Hamiltonian isotopic Lagrangians. We check in an example that $>300$ mutually disjoint curves (and hence Lagrangians) arise. We show that the weight of each of these Lagrangians equals to the multiplicity of the corresponding tropical curve.

Coherent patterns and self-induced diffraction of electrons on a thin nonlinear layer

description: Electron scattering on a thin layer where the potential depends self-consistently on the wave function has been studied. When the amplitude of the incident wave exceeds a certain threshold, a soliton-shaped brightening (darkening) appears on the layer causing diffraction of the wave. Thus the spontaneously formed transverse pattern can be viewed as a self-induced nonlinear quantum screen. Attractive or repulsive nonlinearities result in different phase shifts of the wave function on the screen, which give rise to quite different diffraction patterns. Among others, the nonlinearity can cause self-focusing of the incident wave into a ``beam'', splitting in two ``beams'', single or double traces with suppressed reflection or transmission, etc.

description: New style of teaching science (as inquiry based science teaching) appeared in the French curricula during these last years. Our study focuses on two kind of inquiry based teachings and propose to identify which promote in the better way the processes of problematization during a debate. The theoretical framework of problematization, allowed us to compare two types of inquiry based teachings in two classes of grade 7th having the same problem to solved based on the phenomenon of buoyancy. These two teachings differ in the organization of students' investigation before the debate. The first teaching asks the students to resolve the problem without writing hypothesis, whereas the second necessitates that students write some hypothesis before to handling the experiment. The analysis of video transcriptions of the two sequences have allowed us to show that writing hypothesis seems to promote explanations of students in the register of models during a debate in class, which could allow to them to problematize in a better way.

description: This research builds on the "functional analysis" of technical objects from technology program students from the 7th year in Tunisia (12 year). The aim is to characterize the decisions taken in the classroom to assess and determine their relationship with the taught knowledge. To achieve the results we filmed a session technological education, from which we tried to find the relationships that can exist between the examples from technical object and interactive decisions established. We have developed a methodology tool for both organization and analysis to highlight the real time course of education in a constantly changing environment, with an annotation software and data analysis video.
