Teachers’ Use Of Technology In Punjab’s Schools: A Comparative Case Study Of A Public, A Private, And A Partnership School
Creators: name: Khan, Muhammad S.
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: This research studied teachers’ use of technology in Punjab’s schools. The research questions were: (1) “How are public, private, and partnership schools using technology for teaching purposes?” (2) “What is teachers’ and school administrators’ attitude towards the use of technology for teaching and learning?” (3) “What factors influence their attitude?” (4) “How is their attitude affecting the schools’ teaching and students’ learning?” (5) “What can be done to effectively train the stakeholders in using technology meaningfully for the teaching and learning process?”This qualitative research employed comparative case-study method to study three different types of schools in Punjab province of Pakistan. A public, a private, and a public-private partnership school’s teachers and school leaders were research participants. Semi-structured interviews and relevant official documents provided the data for this study.Findings depicted major weaknesses in Punjab’s teacher training, recruitment and professional development domains. Several intrinsic and extrinsic factors were highlighted by teachers and school leaders to identify those factors’ impact on participants’ attitude and execution of learning with technology. Teacher’s willingness to learn and improve was one of the salient positive results of this study. However, there was not enough evidence of eagerness from national government, provincial government, school owners, or policy makers, to bring about major changes to incorporate a culture that is conducive to meaningful use of technology.The original contribution of this study to the body of knowledge is by depicting the struggle and occasional success of a monolingual (for example, Urdu speaking) teacher trying to make meaningful use of technology, where most of the support is being provided in a foreign language (English). This study highlighted technological, linguistic, gender, cultural, and economic barriers faced by a predominantly female teaching staff while working in the participant schools. Non-meaningful use of technology due to lack of proper training was also studied and potentially rectified using information dissemination workshops.

description: This paper describes the electrodynamics of a null and force-free field in completely geometric terms. As was previously established in \cite{Menon_FF20}, solutions to force-free electrodynamics are governed by the existence of certain special types of foliations of spacetime. Here the nature of the foliations in a coordinate-free formalism in the null case is prescribed. All of the general results are illustrated by constructing a null, force-free electrodynamic field in a Friedmann-Lemaitre-Robertson- Walker (FLRW) spacetime.

description: We introduce a modeling framework called Transaction Cost Economics to help decision makers in rural health care markets choose among alternative organizational relationships in order to more cost-effectively deliver healthcare services. In particular, the hospital-physician relationship is analyzed and the transactional attributes, institutional environment, and market characteristics are identified as key variables influencing the organizational relationship between hospital and physician. As asset specfic investments are made by either the hospital or physician, vertically integrated relationships are more likely to occur. The degree of remoteness of rural areas is also considered to affect the impact of these asset-specific investments.

description: We describe a new experiment to search for neutrinos with energies above 3 x 10^18 eV based on the observation of short duration radio pulses that are emitted from neutrino-initiated cascades. The primary objective of the ANtarctic Impulse Transient Antenna (ANITA) mission is to measure the flux of Greisen-Zatsepin-Kuzmin (GZK) neutrinos and search for neutrinos from Active Galactic Nuclei (AGN). We present first results obtained from the successful launch of a 2-antenna prototype instrument (called ANITA-lite) that circled Antarctica for 18 days during the 03/04 Antarctic campaign and show preliminary results from attenuation length studies of electromagnetic waves at radio frequencies in Antarctic ice. The ANITA detector is funded by NASA, and the first flight is scheduled for December 2006.

description: Conduction electron spin lifetimes ($T_1$) and spin coherence times ($T_2$) are strongly modified in semiconductor quantum wells by electric fields. Quantitative calculations in GaAs/AlGaAs quantum wells at room temperature show roughly a factor of four enhancement in the spin lifetimes at optimal values of the electric fields. The much smaller enhancement compared to previous calculations is due to overestimates of the zero-field spin lifetime and the importance of nonlinear effects.

Publisher: name: University of Leicester

Subjects: Uncategorized

description: The purpose of this work is to improve measurement capabilities for urban pollution monitors, making use of small, rapidly deployable and low-cost sensing solutions. A complete pollution monitoring instrument was designed and introduced in the course of this project, capable of supporting a wide variety of sensors. In this work, Metal Oxide Semiconductor gas sensors were used to measure concentrations of NO2 and O3 at an urban background site on University campus. These two gases are closely linked to traffic pollution and harmful to human health. The sensors were extensively tested in multiple experiments:• Over one month the instrument achieved a residual standard error compared to the AURN reference (a chemiluminescence/UV fluorescence monitor) of 23.6 =/- 3:9 μgm-3 for NO2 and 23.3 =/- 3:9 μgm-3 for O3.• Analysis techniques were introduced to allow comparison of multiple calibrations over a long period. These could then be used to discard poor-quality calibrations, improving performance to a residual standard error of 22.9 =/-5:3 μgm-3 for NO2 and 20.0 =/- 5:1 μgm-3 for O3.• Analysis techniques using separate calibrations for day and night were attempted, but produced very marginal results. Using multiple calibrations produced an improvement in residual standard error for NO2 of 3.4 =/- 6:2 μgm-3 and 1.72 =/- 1:85 μgm-3 for O3. The effects of wind on sensor calibration were demonstrated, but an improvement in sensor performance through analysis could not be practically achieved.• Using these analysis techniques, the effects of instrument design, such as active air flow, sensor \warm-up" time after power-up, and manufacturing variation in the sensors were investigated and two experiments using the unique characteristics of the instrument platform to examine the variation of pollutant gas on a small scale are described.Some of these data analysis procedures are not speci?c to instruments making use of Metal Oxide Semiconductor gas sensors and may prove generally useful for other types of instrument.

description: A major focus of Nb$_3$Sn accelerator magnets is on significantly reducing or eliminating their training. Demonstration of an approach to increase the $C_p$ of Nb$_3$Sn magnets using new materials and technologies is very important both for particle accelerators and light sources. It would improve thermal stability and lead to much shorter magnet training, with substantial savings in machines' commissioning costs. Both Hypertech and Bruker-OST have attempted to introduce high-$C_p$ elements in their wire design. This paper includes a description of these advanced wires, the finite element model of their heat diffusion properties as compared with the standard wires, and whenever available, a comparison between the minimum quench energy (MQE) calculated by the model and actual MQE measurements on wires.

Nuclear Magnetic Relaxation Time near Compensation Temperature in Ferrimagnetic Insulator

description: The nuclear magnetic relaxation time $T_1$ in ferrimagnetic insulators is calculated by a Raman process of hyperfine interaction with a meanfield approximation. It is found that the 1/$T_1$ on one site rapidly increases near the compensation temperature $T_0$, whereas that on another site does not increase up to Curie temperature $T_c$. This is due to that the band width of soft magnon becomes comparable to $T_0$. The increasing behavior of 1/$T_1$ below $T_c$ is found also in another type ferrimagnet, which shows hump structure in the temperature dependence of magnetization instead of compensation. Also in this case, we find the rapid increase of 1/$T_1$ below $T_c$, even though the magnetization does not show the compensation. Such a coexistence of soft and hard magnons will lead to remarkable properties of ferrimagnet.

description: We study the anomalous scaling of the mass density measure of Lagrangian tracers in a compressible flow realized on the free surface on top of a three dimensional flow. The full two dimensional probability distribution of local stretching rates is measured. The intermittency exponents which quantify the fluctuations of the mass measure of tracers at small scales are calculated from the large deviation form of stretching rate fluctuations. The results indicate the existence of a critical exponent $n_c \simeq 0.86$ above which exponents saturate, in agreement with what has been predicted by an analytically solvable model. Direct evaluation of the multi-fractal dimensions by reconstructing the coarse-grained particle density supports the results for low order moments.

description: We develop an inhomogeneous quantum mean-field approach to the behavior of collective excitations across the superfluid–Mott glass quantum phase transition in two dimensions, complementing recent quantum Monte Carlo simulations (Puschmann et al. 2020). In quadratic (Gaussian) approximation, the Goldstone (phase) and Higgs (amplitude) modes completely decouple. Each is described by a disordered Bogoliubov Hamiltonian which can be solved by an inhomogeneous multi-mode Bogoliubov transformation. We find that the Higgs mode is spatially localized in both phases. The corresponding scalar spectral function shows a broad peak that is noncritical in the sense that its peak frequency does not soften but remains nonzero across the quantum phase transition. In contrast, the lowest-energy Goldstone mode delocalizes in the superfluid phase, leading to a zero-frequency spectral peak. We compare these findings to the results of the quantum Monte Carlo simulations. We also relate them to general results on the localization of bosonic excitations, and we discuss the limits and generality of our approach.

description: The continuous ferromagnetic-paramagnetic phase transition in the two-dimensional Ising model has already been excessively studied by conventional canonical statistical analysis in the past. We use the recently developed generalized microcanonical inflection-point analysis method to investigate the least-sensitive inflection points of the microcanonical entropy and its derivatives to identify transition signals. Surprisingly, this method reveals that there are potentially two additional transitions for the Ising system besides the critical transition.

Investigation of Persistence Mechanisms in Staphylococcus aureus Bacteraemia Isolates and The Effect of mprF Gain-of-Function Mutations on Global Gene Regulation

Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: Staphylococcus aureus (S. aureus) bacteraemia is a major serious bacterial infection. Bacteraemia infections due to methicillin-sensitive S. aureus (MSSA) have increased compared to methicillin-resistant S. aureus (MRSA). Moreover, bacteraemia is complicated due to persistence and failure to respond to treatment by an appropriate antibiotic. However, it is unclear how S. aureus evades the host immune system and displays resistance to antibiotics treatment during persistent bacteraemia (PB). Several bacterial traits/mechanisms were previously associated with persistence. The role of multiple peptide resistance factor (MprF) gain-of-function (GoF) during the development of S. aureus persistence has been previously suggested. MprF is a membrane protein that catalyses the lipid synthesis and the translocation of lysyl-phosphatidylglycerol (L-PG) reducing the negative charge of the bacterial cell surface leading to a charge repulsion for cationic molecules.This study aimed to identify the persistence mechanisms in clinical PB (MSSA) isolates and to investigate the role of mprF GoF mutation P314L in mediating persistence via increased bacterial fitness and the expression of immune and adhesion proteins.This study indicates that mutant MprF P314L has different impacts on protein expression via altering the bacterial cell membrane. Proteomics and transcriptional analysis of PB isolates revealed the impact of mprF P314L mutation on increased expression of virulence genes encoding proteins involved in immune evasion and adhesion and persistence (Eap). This study presented a novel role of MprF in the increased transcription level of virulence genes via impacting the expression of the two main virulence regulators, Sae and Agr. In contrast, the transcription of genes regulated by GraSR or LytSR was not affected suggesting the MprF P314L affects virulence genes/proteins expression on different levels. Overall, our data indicates that MprF mediates the development of persistence through changing global gene regulation leading to persistence traits including increased levels of proteins involved in the evasion and adhesion.

description: This article analyzes the way some 6,000 European wine consumers, both connoisseurs and non-connoisseurs, use a set of available signals (price, umbrella branding, goodwill, past consumption) to assess the quality of Bordeaux wines where price is the main source of information on quality. Connoisseurs use this signal less intensively than on connoisseurs. Price represents a substitute for umbrella branding where consumers are not aware of who is beneath this umbrella, and where this signal is thus of no help to them. This could explain why such wines tend nowadays to lose market share in favor of branded wines that are easier to evaluate.

description: Bordeaux wines have been made in much the same way for centuries. This article shows that the variability in the quality and prices of Bordeaux vintages is predicted by the weather that created the grapes. The price equation provides a measure of the real rate of return to holding wines (about 2–3% per annum) and implies far greater variability in the early or ‘en primeur’ wine prices than is observed. The analysis provides a useful basis for assessing market inefficiency, the effect of climate change on the wine industry and the role of expert opinion in determining wine prices.

An investigation of the Ehlers-Clark cognitive theory of PTSD and the phenomenon of mental pollution
Creators: name: Fairbrother, Nichole
Publisher: name: University of British Columbia
Year: 2009

description: Cognitive models have successfully added to our understanding of the onset and maintenance of many anxiety disorders. I tested one component of a recent cognitive model of posttraumatic stress disorder (Ehlers & Clark, 2000) and examined the related phenomenon of mental pollution in a sample of 50 female sexual assault victims. Results indicated that sexual assault appraisals were strongly and positively related to PTSD symptoms. These relations remained significant after statistically controlling for the severity of the assault. Appraisals of the sexual assault and its sequelae explained a significant amount of the variance in PTSD symptoms even after the variance attributable to sexual assault severity was accounted for. Sixty percent of the women interviewed reported some feelings of mental pollution subsequent to the assault. Feelings of mental pollution related to post-assault washing behaviour. Deliberate recall of the assault resulted in stronger feelings of dirtiness and the urge to wash than deliberate attention to a pleasant memory or scene. In response to deliberate recall of the assault memory, nine women reported washing their hands. These findings support the cognitive model of PTSD proposed by Ehlers and Clark, and suggest that the phenomenon of mental pollution is important to our understanding of sexual assault trauma.

description: Topological photonics has emerged as a novel paradigm for the design of electromagnetic systems from microwaves to nanophotonics. Studies to date have largely focused on the demonstration of fundamental concepts, such as non-reciprocity and waveguiding protected against fabrication disorder. Moving forward, there is a pressing need to identify applications where topological designs can lead to useful improvements in device performance. Here we review applications of topological photonics to ring resonator-based systems, including one- and two-dimensional resonator arrays, and dynamically-modulated resonators. We evaluate potential applications such as quantum light generation, disorder-robust delay lines, and optical isolation, as well as future research directions and open problems that need to be addressed.

description: Weather derivatives are a relatively new form of financial security that can provide firms with the ability to hedge against the impact of weather related risks to their activities. Participants in the energy industry have employed standardized weather contracts trading on organized exchanges since 1999 and the interest in non-standardized contracts for specialized weather related risks is growing at an increasing rate. The purpose of this paper is to examine the potential use of weather derivatives to hedge against temperature related risks in Canadian ice wine production. Specifically we examine historical data for the Niagara region of the province of Ontario, Canada, the largest icewine producing region of the world, to determine an appropriate underlying variable for the design of an option contact that could be employed by icewine producers. Employing monte carlo simulation we derive a range of benchmark option values based upon varying assumptions regarding the stochastic process for an underlying temperature variable. The results show that such option contracts can provide valuable hedging opportunities for producers, given the historical seasonal temperature variations in the region.

description: The use of a non-Riemannian measure of integration in the action of strings and branes allows the possibility of dynamical tension. In particular, lower dimensional objects living in the string/brane can induce discontinuities in the tension: the effect of pair creation on the string tension is studied. We investigate then the role that these new features can play in string and brane creation and growth. A mechanism is studied by means of which a scalar field can transfer its energy to the tension of strings and branes. An infinite dimensional symmetry group of this theory is discussed. Creation and growth of bubbles in a formulation that requires mass generation for the bulk gauge fields coupled to the branes is also discussed.

description: Investing in a new perennial crop variety involves an irreversible commitment of capital and generates an uncertain return stream. As a result, the decision to adopt a new variety includes a significant real option value. Waiting for returns to rise above this real option causes a delay in adoption because of economic hysteresis. This study tests for hysteresis in the adoption of wine grape varieties using a sample of district-level data from the state of California. The empirical results show a significant hysteretic effect in wine grape investment, which might be reduced by activities that smooth earnings over time.

Foreign material is the only grade factor closely related to processed value, but a large number of nongrade attributes, many of which reflect the intrinsic properties of corn, are found to vary substantially across shipments and to provide extensive information about value. Recommendations for U.S. grades are made.

description: The neutron skin thickness $Δr_{np}$ in heavy nuclei has been known as one of the most sensitive terrestrial probes of the nuclear symmetry energy around $\frac{2}{3}$ of the saturation density $ρ_0$ of nuclear matter. Existing neutron skin data mostly from hadronic observables suffer from large uncertainties and their extraction from experiments are often strongly model dependent. While waiting eagerly for the promised model-independent and high-precision neutron skin data for $^{208}$Pb and $^{48}$Ca from the parity-violating electron scattering experiments (PREX-II and CREX at JLab as well as MREX at MESA), within the Bayesian statistical framework using the Skyrme-Hartree-Fock model we infer the posterior probability distribution functions (PDFs) of the slope parameter $L$ of the nuclear symmetry energy at $ρ_0$ from imagined $Δr_{np}(^{208}$Pb$)=0.15$, 0.20, and 0.30 fm as well as $Δr_{np}(^{48}$Ca$)=0.12$, 0.15, and 0.25 fm, with different $1σ$ error bars. The results are compared with the PDFs of $L$ inferred using the same approach from the available $Δr_{np}$ data for Sn isotopes from hadronic probes. They are also compared with results from a recent Bayesian analysis of the radius and tidal deformability data of canonical neutron stars from GW170817 and NICER. The neutron skin data for Sn isotopes gives $L=45.5^{+26.5}_{-21.6}$ MeV surrounding its mean value or $L=53.4^{+18.6}_{-29.5}$ MeV surrounding its maximum {\it a posteriori} value, respectively, with the latter smaller than but consistent with the $L=66_{-20}^{+12}$ MeV from the neutron star data within their 68\% confidence intervals. In order to provide additionally useful information on $L$ extracted from the $Δr_{np}$ of Sn isotopes, the experimental error bar of $Δr_{np}(^{208}$Pb) should be at least smaller than 0.06 fm aimed by some current experiments.

description: Magnetars comprise two classes of rotating neutron stars (Soft Gamma Repeaters (SGRs) and Anomalous X-ray Pulsars), whose X-ray emission is powered by an ultrastrong magnetic field, B ~ 10^15 G. Occasionally SGRs enter into active episodes producing many short X-ray bursts; extremely rarely (about once per 50 years per source), SGRs emit a giant flare, an event with total energy at least 1000 times higher than their typical bursts. Here we report that, on 2004 December 27, SGR 1806-20 emitted the brightest extra-solar transient event ever recorded, even surpassing the full moon brightness for 0.2 seconds. The total (isotropic) flare energy is 2x10^46 erg, 100 times higher than the only two previous events, making this flare a once in a century event. This colossal energy release likely occurred during a catastrophic reconfiguration of the magnetar's magnetic field. Such an event would have resembled a short, hard Gamma Ray Burst (GRB) if it had occurred within 40 Mpc, suggesting that extragalactic SGR flares may indeed form a subclass of GRBs.

description: This article presents the MEG II Cylindrical Drift CHamber (CDCH), a key detector for the phase 2 of MEG, which aims at reaching a sensitivity level of the order of $6 \times 10^{-14}$ for the charged Lepton Flavour Violating $μ^+ \rightarrow \mbox{e}^+ γ$ decay. CDCH is designed to overcome the limitations of the MEG $\mbox{e}^+$ tracker and guarantee the proper operation at high rates with long-term detector stability. CDCH is a low-mass unique volume detector with high granularity: 9 layers of 192 drift cells, few mm wide, defined by $\approx 12000$ wires in a stereo configuration for longitudinal hit localization. The total radiation length is $1.5 \times 10^{-3}$ $\mbox{X}_0$, thus minimizing the Multiple Coulomb Scattering (MCS) contribution and allowing for a single-hit resolution of 110 $μ$m and a momentum resolution of 130 keV/c. CDCH integration into the MEG II experimental apparatus will start in this year.

description: This article presents three arguments as to why the value of wine as an investment good has typically been understated and argues that wine investment in the UK and Australia represents a value proposition. It is argued that general all vintage wine indexes understate the return the typical investor receives; that comparisons using pre-tax returns overstate the value of standard financial assets relative to wine; and that wine investment provides value in terms of allowing portfolio risk to be reduced.
New Synthetic Methodologies for Hypervalent Iodine(III)-Mediated Atom-transfer Reactions

description: Hypervalent iodine(III) compounds are attractive reagents in organic synthesis. The main advantages include their low cost and low toxicity. In particular, they have been used as atom-transfer reagents to introduce nucleophiles such as chloride and fluoride into organic compounds. In chapter two, a one-pot synthetic method was designed to introduce a variety of nucleophiles into the 2-position of 1,3-dicarbonyl compounds using fluoroiodane. Chloride, methoxy and ethoxy groups were introduced into a series of 1,3-dicarbonyl compounds in moderate to high yields (32-90 %). The advantage of this method is that only one hypervalent iodine(III) reagent is required to introduce a range of different nucleophiles into the 2-position of 1,3-dicarbonyl compounds, whereas previous methods required a different hypervalent iodine(III) reagent for each nucleophile. Unfortunately, the introduction of either a trifluoromethyl or a trifluoroethoxy group proved unsuccessful due to the low nucleophilicity and steric bulk of these nucleophiles.In chapter three a catalytic method was developed to introduce chlorine into 1,3-dicarbonyl compounds using 2-(2-iodophenyl)propan-2-ol under mild reaction conditions and in good yields (73-76 %). This methodology was applied to the tosyloxylation and fluorination of a β-ketoester with limited success. However, when hexafluoroisopropanol (HFIP) was employed as a solvent, the stoichiometric fluorination was possible. A range of 2-fluoro-1,3-dicarbonyl compounds was synthesised in good to excellent yields using fluoroiodane in HFIP, without the need for Et3N.3HF. 1H NMR studies provided evidence for the activation of fluoroiodane by hydrogen bonding, due to the formation of a hydrogen bonding adduct between fluoroiodane and HFIP.Finally, three chiral iodoarenes were synthesised in chapter four and investigated in the enantioselective chlorination of 1,3-dicarbonyl compounds. Only a small enantiomeric excess was obtained due to issues with background chlorination and hydroxylation. The Gilmour system, employing cesium choride and Selectfluor was explored and preliminary work showed no evidence of a competing background reaction.

description: We demonstrate that unidirectional and backscattering immune propagation of terahertz optical waves can be achieved in a topological valley-Hall waveguide made of graphene nanohole plasmonic crystals. In order to gain deeper physical insights into these phenomena, the band diagram of graphene nanohole plamsonic crystals has been investigated and optimized. We found that a graphene plasmonic crystal with nanohole arrays belonging to the $C_{6v}$ symmetry group possesses gapless Dirac cones, which can be gapped out by introducing extra nanoholes such that the symmetry point group of the system is reduced from $C_{6v}$ to $C_{3v}$. Taking advantage of this feature, we design a mirror symmetric domain-wall interface by placing together two optimized graphene plasmonic crystals so as to construct valley-polarized topological interface modes inside the opened bandgap. Our computational analysis shows that the valley-Hall topological domain-wall interface modes can be achieved at an extremely deep subwavelength scale, and do not rely on the application of external static magnetic fields. This work may pave a new way to develop highly-integrated and robust terahertz plasmonic waveguides at deep-subwavelength scale.

description: Searching for characteristic signatures of a higher order phase transition (specifically of order three or four), we have calculated the spatial profiles and the energies of a spatially varying order parameter in one dimension. In the case of a $p^{th}$ order phase transition to a superconducting ground state, the free energy density depends on temperature as $a^p$, where $a = a_o(1-T/T_c)$ is the reduced temperature. The energy of a domain wall between two degenerate ground states is $ε_p \simeq a^{p-1/2}$. We have also investigated the effects of a supercurrent in a narrow wire. These effects are limited by a critical current which has a temperature dependence $J_c(T) \simeq a^{(2p-1)/2}$. The phase slip center profiles and their energies are also calculated. Given the suggestion that the superconducting transtion in \bkbox, for $x = 0.4$, may be of order four, these predictions have relevance for future experiments.
