Connecting deeply : educator and child relationships in infant and toddler classrooms
Creators: name: Liska, Karen Marie
Publisher: name: The University of British Columbia
Year: 2016

description: In this project I examine the importance and value of secure attachment relationships nurtured between an educator and the children in their care. With increasing numbers of infants and toddlers in large group childcare classrooms, the exploration of “how to be with” young children is essential to ensure quality. The classroom environment is a unique context for fostering connection between educator and child, as these relationships lay the foundation for lifelong development. I frame my project in the sociocultural, ecological systems, and attachment theories, and draw from the psychosocial theory and functional emotional developmental levels of the mind theory. I present literature supportive of primary caregiving practices in childcare settings to illustrate how daily care routines afford moments for interactions, where educators can increase children’s engagement and contributions within the classroom. I offer scenarios drawn from my own experiences and practice that reflect relationships happening in the classroom. I conclude that when educators listen intentionally and respond ethically to a child, they are able to honour the child’s uniqueness, opening a space for the child to participate actively in shaping their own care. In addition, reflective and collaborative relations among educators expand their caring repertoire, and that this, in turn, enriches the relationships between educator and children. I recommend to educators that more emphasis be placed on creating moments throughout the day for interaction and connection with children. I also recommend that increased training be available for educators to enhance their practices and promote quality care.

description: We introduce a class of damage models on regular lattices with isotropic interactions, as e.g. quasistatic fiber bundles. The system starts intact with a surface-energy threshold required to break any cell sampled from an uncorrelated quenched-disorder distribution. The evolution of this heterogeneous system is ruled by Griffith's principle which states that a cell breaks when the release in elastic energy in the system exceeds the surface-energy barrier necessary to break the cell. By direct integration over all possible realizations of the quenched disorder, we obtain the probability distribution of each damage configuration at any level of the imposed external deformation. We demonstrate an isomorphism between the distributions so obtained and standard generalized Ising models, in which the coupling constants and effective temperature in the Ising model are functions of the nature of the quenched-disorder distribution and the extent of accumulated damage. In particular, we show that damage models with global load sharing are isomorphic to standard percolation theory, that damage models with local load sharing rule are isomorphic to the standard Ising model, and draw consequences thereof for the universality class and behavior of the autocorrelation length of the breakdown transitions corresponding to these models. We also treat damage models having more general power-law interactions, and classify the breakdown process as a function of the power-law interaction exponent. Last, we also show that the probability distribution over configurations is a maximum of Shannon's entropy under some specific constraints related to the energetic balance of the fracture process, which firmly relates this type of quenched-disorder based damage model to standard statistical mechanics.

Why binary interaction does not necessarily dominate the formation of Wolf-Rayet stars at low metallicity

description: Classical Wolf-Rayet (WR) stars are massive, hydrogen depleted, post main-sequence stars that exhibit emission-line dominated spectra. For a given metallicity Z, stars exceeding a certain initial mass M_single(Z) can reach the WR phase through intrinsic mass-loss (single-star channel). Stars of lower masses can reach the WR phase via binary mass transfer (binary channel). It is commonly assumed that the binary channel dominates the formation of WR stars in environments with low Z such as the SMC and LMC. However, their reported WR binary fractions of 30-40% are comparable to that of the Galaxy. Here, we explain this apparent contradiction by considering the minimum initial mass M_spec(Z) needed for the stripped product to appear as a WR star. We calibrate M_spec(Z) using the lowest-luminosity WR stars in the Clouds and the Galaxy. A range of M_single(Z) values are explored using various evolution codes. We estimate the additional contribution of the binary channel by considering the interval [M_spec(Z), M_single(Z)], which characterises the initial-mass range in which binaries can form additional WR stars. Results: The WR-phenomenon ceases below luminosities of logL = 4.9, 5.25, and 5.6 [Lsun] in the Galaxy, LMC, and SMC, which translates to He-star masses of 7.5, 11, 17 Msun and initial masses of M_spec = 18, 23, 37 Msun. Stripped stars with lower initial masses in the respective galaxies would tend to not appear as WR stars. M_single lies in the range 20-30, 30-60, and > 40 Msun for the Galaxy, LMC, and SMC. We find that that the additional contribution of the binary channel is a non-trivial function of Z that cannot be conclusively claimed to be monotonically increasing with decreasing Z. Hence, one should not a-priori expect that binary interactions become increasingly important in forming WR stars at low Z, or that the WR binary fraction grows with decreasing Z.

description: Fuzzy logic controllers are readily customizable in natural language terms and can effectively deal with nonlinearities and uncertainties in control systems. This paper presents an intelligent and automated fuzzy control procedure for the refrigerant charging of refrigerators. The elements that affect the experimental charging and the optimization of the performance of refrigerators are fuzzified and used in an inference model. The objective is to represent the intelligent behavior of a human tester and ultimately make the developed model available for the use in an automated data acquisition, monitoring, and decision-making system. The proposed system is capable of determining the needed amount of refrigerant in the shortest possible time. The system automates the refrigerant charging and performance testing of parallel units. The system is built using data acquisition systems from National Instruments and programmed under LabVIEW. The developed fuzzy models, and their testing results, are evaluated according to their compatibility with the principles that govern the intelligent behavior of human experts when performing the refrigerant-charging process. In addition, comparisons of the fuzzy models with classical inference models are presented. The obtained results confirm that the proposed fuzzy controllers outperform traditional crisp controllers and provide major test time and energy savings. The paper includes thorough discussions, analysis, and evaluation.

description: We introduce a new numerical scheme for solving the initial value problem for quasiequilibrium binary neutron stars allowing for arbitrary spins. The coupled Einstein field equations and equations of relativistic hydrodynamics are solved in the Wilson-Mathews conformal thin sandwich formalism. We construct sequences of circular-orbit binaries of varying separation, keeping the rest mass and circulation constant along each sequence. Solutions are presented for configurations obeying an n=1 polytropic equation of state and spinning parallel and antiparallel to the orbital angular momentum. We treat stars with moderate compaction ((m/R) = 0.14) and high compaction ((m/R) = 0.19). For all but the highest circulation sequences, the spins of the neutron stars increase as the binary separation decreases. Our zero-circulation cases approximate irrotational sequences, for which the spin angular frequencies of the stars increases by 13% (11%) of the orbital frequency for (m/R) = 0.14 ((m/R) = 0.19) by the time the innermost circular orbit is reached. In addition to leaving an imprint on the inspiral gravitational waveform, this spin effect is measurable in the electromagnetic signal if one of the stars is a pulsar visible from Earth.

description: The study investigated the effects of Jatropha curcas (JC) and Vetiveria zizanioides (VZ) on hydrocarbon concentration levels in mine spoils. A 2 × 2 × 3 factorial arrangement of treatments in a completely randomized design with 3 replications was adopted. With compost amendments, JC caused 78.8 and 82.2% and VZ caused 51.1 and 39.7% decline in soil TPH and TOG concentrations, respectively after 16 weeks. Compost amendments significantly reduced TOG and TPH concentrations compared to the other treatments in both JC and VZ (p p = 0.081 and p p p = 0.009) and collar diameter growth (p = 0.010) were significantly lower in contaminated soils compared to non-contaminated soils. Furthermore, only the number of tillers in Vetiver was significantly influenced by the soil amendments (p = 0.003) and the soil hydrocarbon levels (p = 0.048). It is concluded that phytoremediation particularly with JC is an alternate means to reducing soil hydrocarbon concentration levels. However, soils must be amended with compost for effective remediation and rapid, vigorous, early growth of plants.

description: OCaml is an industrial-strength, multi-paradigm programming language, widely used in industry and academia. OCaml is also one of the few modern managed system programming languages to lack support for shared memory parallel programming. This paper describes the design, a full-fledged implementation and evaluation of a mostly-concurrent garbage collector (GC) for the multicore extension of the OCaml programming language. Given that we propose to add parallelism to a widely used programming language with millions of lines of existing code, we face the challenge of maintaining backwards compatibility--not just in terms of the language features but also the performance of single-threaded code running with the new GC. To this end, the paper presents a series of novel techniques and demonstrates that the new GC strikes a balance between performance and feature backwards compatibility for sequential programs and scales admirably on modern multicore processors.

A time-resolved Kerr rotation microscope with approximately 1 micron spatial resolution uses electron spin precession to directly image the GaAs nuclear polarization. These measurements indicate that the polarization varies from a maximum under magnetic mesas to zero several microns from the mesa perimeter, resulting in large (10**4 T/m) effective field gradients. The results reveal a flexible scheme for lateral engineering of spin-dependent energy landscapes in the solid state.

description: We present an active feedback scheme acting continuously on the state of a quantum gas dispersively coupled to a high-finesse optical cavity. The quantum gas is subject to a transverse pump laser field inducing a self-organization phase transition, where the gas acquires a density modulation and photons are scattered into the resonator. Photons leaking from the cavity allow for a real-time and non-destructive readout of the system. We stabilize the mean intra-cavity photon number through a micro-processor controlled feedback architecture acting on the intensity of the transverse pump field. The feedback scheme can keep the mean intra-cavity photon number $n_\text{ph}$ constant, in a range between $n_\text{ph}=0.17\pm 0.04$ and $n_\text{ph}=27.6\pm 0.5$, and for up to 4 s. Thus we can engage the stabilization in a regime where the system is very close to criticality as well as deep in the self-organized phase. The presented scheme allows us to approach the self-organization phase transition in a highly controlled manner and is a first step on the path towards the realization of many-body phases driven by tailored feedback mechanisms.

description: Per and polyfluoroalkyl substances (PFAS) consist of a large group of compounds used to make products more resistant to stains, grease, and water and for fire suppression. They have been widely detected in the environment and exposure has been linked to adverse human health effects. Phytoremediation could be used to remediate PFAS-impacted sites, but there is little information on herbaceous and woody plant species uptake of PFAS compounds from soil. A greenhouse study evaluated the potential for eight herbaceous and seven woody plant species to absorb PFAS compounds. Six PFAS compounds: PFPeA, PFHxA, PFOA, PFBS, PFHxS, and PFOS were added weekly to irrigation water, and the plants grown for up to 14 weeks after an initial establishment period. Significant accumulation of all PFAS compounds occurred in at least one plant species. Mass recovery in above-ground tissue by the best performing plant ranged from a low of 3.8% for PFOS by Festuca rubra to a high of 42% for PFPeA by Schedonorus arundinaceus. Hyperaccumulation, defined as tissue/soil concentrations >10/1, was observed for all six PFAS compounds in at least one plant species. These results demonstrate the potential use of phytoremediation as a tool for remediating PFAS-contaminated sites.
title: The development of behaviour, particularly play, in young baboons
Creators: name: Rowland, Charles Garnet
Publisher: name: The Open University
Year: 1983

description: Baboons were observed in two British safari parks for 15 and 3 months. Quantitative data, on the frequencies of play and non-play motor patterns and on temporal associations between motor patterns, are used to provide a description of behaviour development and to investigate the validity and possible heterogeneity of the play category. Infant development was comparable with that reported elsewhere for caged and wild macaques and baboons. Mothers tended to be restrictive, possibly because of stressful conditions in safari parks. As infants became more independent they increasingly manipulated objects away from their mothers. Object manipulation was mostly nutritional but a measure of extended contact with objects is argued to be an index of investigation or manipulatory practice. There is no strong evidence to suggest this was a form of play. Mobile activity was greatest while infants still associated closely with their mothers who were probably satisfying most of their nutritional needs. Locomotor patterns appeared in play once they were established in the general repertoire; a result contrary to the practice hypothesis of play's function. Measures of play locomotor pattern frequency increased markedly at about 6 months. Playful behaviour may have become more beneficial. At that age the black natal colouration was finally lost; and without the social immunity which it might have afforded, infants more frequently performed potentially disruptive behaviours playfully. The development of play wrestling showed a change from a predominantly clinging to a predominantly manipulative form. This is discussed with reference to exercise regimes, age class of play partners and developing manipulative skills. The composition of play varied according to the difference between partners' ages. Developmental and temporal clusters of motor patterns demonstrate that play, as defined in this study, was a heterogeneous but genuine phenomenon.

description: Three notions of complementarity - operational, probabilistic, and value complementarity - are reanalysed with respect to the question of joint measurements and compared with reference to some examples of canonically conjugate observables. It is shown that the joint measurability of noncommuting observables is a consequence of the quantum formalism if unsharp observables are taken into account; a fact not in conflict with the idea of complementarity, which, in its strongest version, was originally formulated only for sharp observables. As an illustration of the general theory, the wave-particle duality of photons is analysed in terms of complementary path and interference observables and their unsharp joint measurability.

description: In the quest for a sustainable environment and clean water resources, the efficacy of Ocimum gratissimum leave (OGL) for indigo carmine (IC) dye biosorption was studied in a batch technique. The physicochemical properties of OGL supported its suitability for biosorption studies. Of 92.6% removal efficiency was achieved at optimum conditions of pH 2, contact time 120 min, initial IC concentration 500 ppm, temperature 298 K, and 100 mg OGL dose. Kinetic data were best fitted to pseudo second-order (PSO) and the mechanism was pore diffusion governed as validated by sum of square error (SSE) and non-linear chi-square (χ2). Freundlich isotherm model gave the best description at 298 K as supported by Halsey, Redlich–Peterson, and Fowler–Guggenheim confirming the heterogeneous nature of OGL and multilayer biosorption process. Langmuir Qmax (77.52 mg g−1) surpassed those previously reported. SEM and EDX confirmed the reality of the biosorption process. Thermodynamic parameters (ΔH°, ΔS°, ΔG°, and Ea) affirm a feasible, spontaneous, exothermic, and randomness of the process. Results revealed that OGL is a potential and efficient environmentally benign, low cost, and sustainable biosorbents. It is therefore recommended as a bi-functional biosorbent for wastewater treatment.

description: Non-perturbative constraints on many body physics--such as the famous Lieb-Schultz-Mattis theorem--are valuable tools for studying strongly correlated systems. To this end, we present a number of non-perturbative results that constrain the low-energy physics of systems having conserved dipole moments. We find that for these systems, a unique translationally invariant gapped ground state is only possible if the polarization of the system is integer. Furthermore, if a lattice system also has $U(1)$ subsystem charge conservation symmetry, a unique gapped ground state is only possible if the particle filling along these subsystems is integer. We also apply these methods to spin systems, and determine criteria for the existence of a new type of magnetic response plateau in the presence of a non-uniform magnetic field. Finally, we formulate a version of Luttinger's theorem for 1D systems consisting of dipoles.

description: We relate $ϕ(\bf{x},s)$, the average number of sites at a transverse distance $\bf{x}$ in the directed animals with $s$ sites in $d$ transverse dimensions, to the two-point correlation function of a lattice gas with nearest neighbor exclusion in $d$ dimensions. For large $s$, $ϕ(\bf{x},s)$ has the scaling form $\frac{s}{R_s^d} f(|\bf{x}|/R_s)$, where $R_s$ is the root mean square radius of gyration of animals of $s$ sites. We determine the exact scaling function for $d =1$ to be $f(r) = \frac{\sqrtπ}{2 \sqrt{3}}erfc(r/\sqrt{3})$. We also show that $ϕ(\bf{x}=0,s)$ can be determined in terms of the animals number generating function of the directed animals.

Relativity of GPS Measurement

description: The relativity of Global Positioning System (GPS) pseudorange measurements is explored within the geometrical optics approximation in the curved space-time near Earth. A space-time grid for navigation is created by the discontinuities introduced in the electromagnetic field amplitude by the P-code broadcast by the GPS satellites. We compute the world function of space-time near Earth, and we use it to define a scalar phase function that describes the space-time grid. We use this scalar phase function to define the measured pseudorange, which turns out to be a two-point space-time scalar under generalized coordinate transformations. Though the measured pseudorange is an invariant, it depends on the world lines of the receiver and satellite. While two colocated receivers measure two different pseudoranges to the same satellite, they obtain correct position and time, independent of their velocity. We relate the measured pseudorange to the geometry of space-time and find corrections to the conventional model of pseudorange that are on the order of the gravitational radius of the Earth.

description: Experimental analysis of the motion in a system of two coupled oscillators with arbitrary initial conditions was performed and the normal coordinates were obtained directly. The system consisted of two gliders moving on an air track, joined together by a spring and joined by two other springs to the fixed ends. From the positions of the center of mass and the relative distance, acquired by analysis of the digital video of the experiment, normal coordinates were obtained, and by a non linear fit the normal frequencies were also obtained. It is shown that although the masses of the springs are relatively small compared to that of the gliders, it is necessary to take them into consideration to improve the agreement with the experimental results. This experimental-theoretical proposal is targeted to an undergraduate laboratory.

description: We study the interference between the amplitudes for $gg \rightarrow X \rightarrow gg$, where $X$ is a new heavy digluon resonance, and the QCD background $gg \rightarrow gg$, at the Large Hadron Collider. The interference produces a large low-mass tail and a deficit of events above the resonance mass, compared to the naive pure resonance peak. For a variety of different resonance quantum numbers and masses, we evaluate the signal-background interference contribution at leading order, including showering, hadronization, and detector effects. The resulting new physics dijet mass distribution may have a shape that appears, after QCD background fitting and subtraction, to resemble an enhanced peak, a shelf, a peak/dip, or even a pure dip. We argue that the true limits on new digluon resonances are likely to differ significantly from the limits obtained when interference is neglected, especially if the branching ratio to $gg$ is less than 1.

description: Σκοπός της παρούσας μεταπτυχιακής εργασίας είναι η μελέτη των τοιχογραφιών στο παρεκκλήσι του αγίου Ιωάννη του Θεολόγου, στο κελλί του Αγίου Προκοπίου της μονής Βατοπαιδίου. Σε αυτό το πλαίσιο εξετάσαμε το εικονογραφικό πρόγραμμα του παρεκκλησίου και αναλύσαμε την κάθε τοιχογραφία ξεχωριστά. Έπειτα παρουσιάσαμε το έργο και την δράση του ζωγράφου Αντωνίου. Ο καλλιτεχνης Αντώνιος είναι ένας ιδιαίτερος ζωγράφος με ξεχωριστή καλλιτεχνηκή ιδιοσυγρασία, για τον οποίο η έρευνα εως σήμερα είναι ελλειπής. Ωστόσο, μέσα από την μελέτη των τοιχογραφιών του παρεκκλησιού του αγίου Ιωάννη του Θεολόγου, καταφέραμε να γνωρίσουμε το σύνολο του έργου που αποδίδεται στον ζωγράφο Αντώνιο και παράλληλα επιχειρήσαμε να αποκωδικοποιήσουμε το έργο και την τεχνική αυτού του αινιγματικού καλλιτέχνη. Έτσι, μέσα από αυτή την μελέτη επιχειρούμε να αναδείξουμε τις τοιχογραφίες (15ος και 16ος αι.) ένος άγνωστου εν πολλοις μνημείου και παράλληλα προδοκούμε η παρούσα μελέτη να βάλει την βάση και να ανοιξει τον δρόμο για την περαιτέρο μελέτη του ζωγραφού Αντώνίου στο μέλλον
description: The aim of the present thesis is the study of frescoes in the chapel of Saint John Theologos, in the cell of Saint Procopios in the monastery of Vatopedi. In this context we examined the chapel’s pictorial program and we analyzed the iconographic features of each mural. After this analyses we presented the work and the action of the painter Antonios. This artist was an interesting painter with unique artistic temperament, for whom the research is deficient. Through the study of chapel’s frescoes, we achieved to come in touch with Antonios’ artworks and at the same time we figured out the technic of this mysterious painter. Taking all these elements into account we tried to present the frescoes (15th and 16th centuries) of this unknown monument and at the same time we hope that this study will attract the interest of the research and it will open the field for further study associated with Antonios in the future

description: Among the numerous agrochemicals in use today, the herbicide 2,4-dichlorophenoxy acetic acid (2,4-D), has been widely applied to control broad-leaved weeds in gardens and farming. 2,4-D is commonly preferred because of its low cost and good selectivity. On the other hand, 2,4-D is a poorly biodegradable pollutant. Therefore, this study has focused on the adsorption of 2,4-D from aqueous solutions by using activated carbon. The activated carbon was produced from the orange (Citrus sinensis L.) pulp by chemical activation with zinc chloride. The morphological and chemical characteristics of the activated carbon were investigated by infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and N2-adsorption techniques. Then, the effect of adsorption parameters was researched for 2,4-D adsorption on activated carbon. The experimental data indicated that the adsorption isotherms were well described by the Langmuir equilibrium isotherm equation and the calculated adsorption capacity was 71.94 mg g−1 at 298 K. The adsorption kinetic of 2,4-D obeys the pseudo-second-order kinetic model. The thermodynamic parameters indicated a feasible, spontaneous and exothermic adsorption. These results show that the prepared activated carbon has good potential for the removal of 2,4-D from aqueous solutions.

description: We study brane recombination for supersymmetric configurations of intersecting branes in terms of the world-volume field theory. This field theory contains an impurity, corresponding to the degrees of freedom localized at the intersection. The Higgs branch, on which the impurity fields condense, consists of vacua for which the intersection is deformed into a smooth calibrated manifold. We show this explicitly using a superspace formalism for which the calibration equations arise naturally from F- and D-flatness.

Newcomer families with children with developmental delays : experiences with service utilization
Creators: name: Morin, Cindy
Publisher: name: The University of British Columbia

description: In this project I explore the literature on newcomer families’ experiences and perceptions in raising children with developmental delays in Canada. In addition, I examine the aspects many newcomers to Canada experience related to immigration which may present as barriers to accessing services, including language and belief systems. Theoretical frameworks that guide this project include socio-cultural theory, ecological systems theory and social learning theory. I also draw on communities of practice framework (CoP) that is grounded on social learning theory. This project explores the extant literature that examines newcomer families’ perceptions, values, and beliefs about their children with developmental delays. Additionally, I draw on the extant literature on health literacy—people who possess the ability to read and comprehend health promotion information. Likewise, I draw on the notion of cultural competency—service providers who practice cultural competency possess the ability to value others’ views of the world. Included in the literature review is an examination of strategies that work for newcomers when seeking-services. Therefore, I point to how early intervention services, education, and government agencies need to become aware of newcomers’ unique perspectives and experiences in order to facilitate and encourage families in seeking early intervention for their children. To address these potential barriers, I propose ways to practice culturally sensitive services at a community level. I include recommendations that early intervention, education and social services adopt the findings from health literacy literature as an approach to address barriers associated with newcomers seeking-services.
