description: The purpose of this study was to determine the impact of supplemental small group
spelling instruction on the spelling skills of first grade students. The researcher wished to
examine the effects of providing a more direct method of instruction on the ability to
spell novel words in isolation. Students initially were assessed on their differentiated
spelling levels using the Words Their Way Spelling Program. Based on these assessment
results, students were placed in homogenous groups, half of which received the
supplemental intervention and half of which received only whole group spelling
instruction. Pre and post-intervention data were compared for three units over a six-week
period. Results indicated that there was not a significant difference in the spelling gains
of the treatment and control groups. However, the treatment group did exhibit slightly
larger gains than the control group in all three units assessed. The findings suggested that small group spelling instruction should continue as it has a
positive impact on students’ spelling abilities, and provides teachers with data to help
make instructional decisions. Identifying ways to implement the instructional groups
most efficiently and to have the most benefit warrants further study.

description: Our knowledge of the dynamics of stars has undergone a revolution thanks to the simultaneous large amount of high-quality photometric observations collected by space-based asteroseismology and ground-based high-precision spectropolarimetry. They allowed us to probe the internal rotation of stars and their surface magnetism in the whole Hertzsprung-Russell diagram. However, new methods should still be developed to probe the deep magnetic fields in those stars. Our goal is to provide seismic diagnoses that allow us to sound the internal magnetism of stars. Here, we focus on asymptotic low-frequency gravity modes and high-frequency acoustic modes. Using a first-order perturbative theory, we derive magnetic splittings of their frequencies as explicit functions of stellar parameters. As in the case of rotation, we show how asymptotic gravity and acoustic modes can allow us to probe the different components of the magnetic field in the cavities where they propagate. This demonstrates again the high potential of using mixed-modes when this is possible.

description: We carry out climate simulations for 1880-2003 with GISS modelE driven by ten measured or estimated climate forcings. An ensemble of climate model runs is carried out for each forcing acting individually and for all forcing mechanisms acting together. We compare side-by-side simulated climate change for each forcing, all forcings, observations, unforced variability among model ensemble members, and, if available, observed variability. Discrepancies between observations and simulations with all forcings are due to model deficiencies, inaccurate or incomplete forcings, and imperfect observations. Although there are notable discrepancies between model and observations, the fidelity is sufficient to encourage use of the model for simulations of future climate change. By using a fixed well-documented model and accurately defining the 1880-2003 forcings, we aim to provide a benchmark against which the effect of improvements in the model, climate forcings, and observations can be tested. Principal model deficiencies include unrealistically weak tropical El Nino-like variability and a poor distribution of sea ice, with too much sea ice in the Northern Hemisphere and too little in the Southern Hemisphere. The greatest uncertainties in the forcings are the temporal and spatial variations of anthropogenic aerosols and their indirect effects on clouds.

description: The purpose of this pre-experimental design case study was to examine the effectiveness of direct vocabulary instruction on reading comprehension skills of a 1st grade student with autism. The measurement tool for this study was comprehension quick checks from Reading A-Z (http://www.reading a-z.com). The student in this study functioned as his own control under alternating patterns of fiction and nonfiction. The conditions were alternated weekly in an ABABABAB design. During the first condition, the student received direct comprehension strategy instruction. In the second condition, the student had direct vocabulary instruction in addition to comprehension strategy instruction. Dependent variable data was collected during the spring 2015 semester. The total quick check scores from the two conditions were compared; however, the scores were not subjected to statistical analysis due to a sample size of one. The data indicates a trend in which the subject performed better when receiving direct vocabulary instruction. Implications and recommendations for future research are discussed.

Reach Lode, Cambridgeshire. When was it dug?
Creators: name: Chisholm, Michael
Publisher: name: Archaeology Data Service

description: Proceedings of the Cambridge Antiquarian Society, 112, 99-111
description: It is well known that Reach was an important medieval inland port, connected to the river Cam and the Fenland waterways by an artificial channel of unknown date, Reach Lode. It is widely believed that the Lode was first dug in Roman times. Reach Lode is particularly important because, uniquely among the East Cambridgeshire lodes, it has seemed that there was reliable evidence for dating its origin. However, when the evidence for a Roman origin is examined, it becomes apparent that the attribution should be reviewed, forcing consideration of an alternative Anglo-Saxon or post-Norman Conquest date for a lode. As will be shown, there is a fundamental problem in the literature from as early as 1933 and continuing up to the present day. Scholars have assumed that a Roman waterway connection between Reach and the Cam at Upware could only have been achieved by means of an artificial channel virtually all the way. What has not been considered is the possibility that a natural stream may have been used.

description: In the novel superfluid polar phase realized in liquid 3He in highly anisotropic aerogels, a quantum transition to the polar-distorted A (PdA) phase may occur at a low but finite pressure Pc(0). It is shown that a nontrivial quantum dynamics of the critical fluctuation of the PdA order is induced by the presence of both the columnar-like impurity scattering leading to the Anderson's Theorem for the polar phase and the line node of the quasiparticle gap in the state, and that, in contrast to the situation of the normal to the B phase transition in isotropic aerogels, a weakly divergent behavior of the compressibility appears in the quantum critical region close to Pc(0).

description: Research into Cambridge's later prehistoric pottery collections, curated by the Museum of Archaeology and Anthropology, has identified a small, largely forgotten, group of Late Bronze Age pottery from Green End Road, Chesterton, accessioned in the early 1930s. Although components of the collection have been illustrated in the intervening years, and assigned varying dates, the group has never been fully published. This paper examines the history of the collection and provides a fully qualified overview of the material. It discusses the date of the pottery and its affinities with other published assemblages from the Cambridge Region. Importantly, it highlights that the group was recovered from the same locale as a large contemporary 'founder's hoard'.

description: We present globally regular vortex-type solutions for a pure SU(2) Yang-Mills field coupled to gravity in 3+1 dimensions. These gravitating vortices are static, cylindrically symmetric and purely magnetic, and they support a non-zero chromo-magnetic flux through their cross section. In addition, they carry a constant non-Abelian current, and so in some sense they are analogs of the superconducting cosmic strings. They have a compact central core dominated by a longitudinal magnetic field and endowed with an approximately Melvin geometry. This magnetic field component gets color screened in the exterior part of the core, outside of which the fields approach exponentially fast those of the electrovacuum Bonnor solutions with a circular magnetic field. In the far field zone the solutions are not asymptotically flat but tend to vacuum Kasner metrics.

Applications of a retroviral integrase towards substrate DNA in vivo
Creators: name: Heale, John-Paule
Publisher: name: University of British Columbia
Year: 2009

description: This study explored the efficacy of using retroviral integrase expressed transiently in vivo to mediate the recombination of exogenous DNA into host cell chromatin. Stable recombination of a substrate DNA into the genome of Baby Hamster Kidney (BHK) cells was achieved by co-transfecting them with a circular plasmid encoding Rous Sarcoma Virus (RSV) integrase (pIN) and a linearized plasmid (pNR) serving as a substrate for the integrase. Ndel linearized pNR (substrate DNA) mimicked the wild type RSV viral DNA in being a linear, double-stranded DNA molecule possessing terminal sequences recognizable by the integrase. Either a dihydrofolate reductase or neomycin cassette engineered into pNR served as a marker for recombination by conferring resistance to methotrexate or G418 selection, respectively. After 10 days growth in media supplemented with either 500µM methotrexate or 575µM G418, a small number of discrete colonies had formed on control plates containing cells which had been transfected only with substrate DNA. However, plates containing cells which had been co-transfected with both substrate DNA and pIN showed a ten-fold or higher increase in colony numbers over control plates. Sequence analysis of co-transfected BHK genomes identified many clonal recombinants; however none was a conserved, full length substrate DNA molecule expected from RSV IN mediated integration. Southern blot analysis of genomic DNA from co-transfected cells indicated that multiple copies of pNR had recombined with the BHK. Hence, in vivo, integrase increases the frequency of recombination of a recognizable substrate DNA molecule. However RSV IN mediated integration of substrate DNA was not observed.

description: Gamma-ray bursts, which are among the most violent events in the universe, are one of the few viable candidates to produce ultrahigh energy cosmic rays. Recently, observations have revealed that GRBs generally originate from metal-poor galaxies and do not directly trace cosmic star formation, as might have been assumed from their association with core-collapse supernovae. Several implications follow from these findings. The redshift distribution of observed GRBs is expected to peak at higher redshift (compared to cosmic star formation), which is supported by the mean redshift of the Swift GRB sample, ~3. If GRBs are, in fact, the source of the observed UHECR, then cosmic-ray production would evolve with redshift in a stronger fashion than has been previously suggested. This necessarily leads, through the GZK process, to an enhancement in the flux of cosmogenic neutrinos, providing a near-term approach for testing the gamma-ray burst-cosmic ray connection with ongoing and proposed UHE neutrino experiments.

description: Distributed opportunistic scheduling is studied for wireless ad-hoc networks, where many links contend for one channel using random access. In such networks, distributed opportunistic scheduling (DOS) involves a process of joint channel probing and distributed scheduling. It has been shown that under perfect channel estimation, the optimal DOS for maximizing the network throughput is a pure threshold policy. In this paper, this formalism is generalized to explore DOS under noisy channel estimation, where the transmission rate needs to be backed off from the estimated rate to reduce the outage. It is shown that the optimal scheduling policy remains to be threshold-based, and that the rate threshold turns out to be a function of the variance of the estimation error and be a functional of the backoff rate function. Since the optimal backoff rate is intractable, a suboptimal linear backoff scheme that backs off the estimated signal-to-noise ratio (SNR) and hence the rate is proposed. The corresponding optimal backoff ratio and rate threshold can be obtained via an iterative algorithm. Finally, simulation results are provided to illustrate the tradeoff caused by increasing training time to improve channel estimation at the cost of probing efficiency.

description: Even as economic growth in the later 1700s brought farmers opportunity nationwide, much of the Fens drained for them 125 years earlier was threatened by flood. The land was saved partly by local engineering. Around the Haddenham Level, drainage windmills were built or improved and, latterly, two catchwaters cut. Fieldwork was undertaken on two of the mills and both catchwaters. Diverse documentation helps to specify chronology and causes from local to global. The received interpretation of how the 'Age of the Windmill' ended can be revised.

description: We investigate the solution landscapes of the confined diblock copolymer and homopolymer in two-dimensional domain by using the extended Ohta--Kawasaki model. The projected saddle dynamics method is developed to compute the saddle points with mass conservation and construct the solution landscape by coupling with downward/upward search algorithms. A variety of novel stationary solutions are identified and classified in the solution landscape, including Flower class, Mosaic class, Core-shell class, and Tai-chi class. The relationships between different stable states are shown by either transition pathways connected by index-1 saddle points or dynamical pathways connected by a high-index saddle point. The solution landscapes also demonstrate the symmetry-breaking phenomena, in which more solutions with high symmetry are found when the domain size increases.

Numerical strategies for the solution of inverse problems
Creators: name: Haber, Eldad
Publisher: name: University of British Columbia
Year: 2009

description: This thesis deals with the numerical solutions of linear and nonlinear inverse problems. The goal of this thesis is to review and develop new techniques for solving such problems. In so doing, the computational tools for solving inverse problems are comprehensively studied. The thesis can be divided into two parts. In the first part, linear inverse theory is dealt with. Methods to estimate noise and efficiently invert large and full matrixes are reviewed and developed. Emphasis is given to Generalized Cross Validation (GCV) for noise estimation, and to Krylov space methods for efficient methods to invert large systems. This part is summarized by applying and comparing the methods developed on linear inverse problems which arise in gravity and tomography. In the second part of this thesis, extensive use of the linear algebra and the noise estimation methods which were developed in the first part of the thesis is made. A review of the current methods to carry out nonlinear inverse problems is given. A test example is constructed to demonstrate that these methods may fail. Next, a new algorithm for solving nonlinear inverse problems is developed. The algorithm is based on the ability to differentiate between correlated errors which comes from the linearization, and non-correlated noise which comes from the measurement. Based on these two types of noise, a regularization procedure which has two parts is developed. The first part is made of global regularization, to deal with the measurement noise, and the second part is made from a local regularization, to deal with the nonlinearity. The thesis demonstrates that GCV can be used in order to determine the measurement noise, and the Damped Gauss- Newton method can be used in order to deal with the local nonlinear terms. Another aspect of nonlinear inverse theory which is developed in this work concerns approximate sensitivities. A new formulation is suggested for the approximate sensitivities and bounds are calculated using this formulation. This part is summarized by applying the techniques to the nonlinear gravity problem and to the magnetotelluric problem.

Although the null hypothesis was supported, there was significant increase in students’ gains for reading and spelling sight words for both the control and experimental groups. Studies related to this topic should continue and should be conducted for longer periods of time, should utilize more students, and should cross examine scores with overall reading achievement.

description: Proceedings of the Cambridge Antiquarian Society, 112, 151-166
description: The centenary of Cyril Fox's publication the Archaeology of the Cambridge Region (ACR) in 1923 by Cambridge University Press is an opportune moment to explore the impact of Fox's work on the understanding of the Cambridge region, and, writ large, on archaeology itself. Fox was not the first to bring the weight of geography and environment alongside archaeological evidence, but he was first to make a convincing case for its landscape-scale perspective, for dividing the region into areas, and producing a quality series of maps based on conventional periods. In this paper, Fox's ACR is discussed in terms of what it produced for an understanding of the Cambridge region in the 1920s and how this has changed, but also what impact his approach to landscape brought to the discipline of archaeology, and in what ways this continues to have resonance today.

description: Distributed opportunistic scheduling (DOS) protocols are proposed for multiple-input multiple-output (MIMO) ad-hoc networks with contention-based medium access. The proposed scheduling protocols distinguish themselves from other existing works by their explicit design for system throughput improvement through exploiting spatial multiplexing and diversity in a {\em distributed} manner. As a result, multiple links can be scheduled to simultaneously transmit over the spatial channels formed by transmit/receiver antennas. Taking into account the tradeoff between feedback requirements and system throughput, we propose and compare protocols with different levels of feedback information. Furthermore, in contrast to the conventional random access protocols that ignore the physical channel conditions of contending links, the proposed protocols implement a pure threshold policy derived from optimal stopping theory, i.e. only links with threshold-exceeding channel conditions are allowed for data transmission. Simulation results confirm that the proposed protocols can achieve impressive throughput performance by exploiting spatial multiplexing and diversity.

title: Multiple-Object Estimation Techniques for Challenging Scenarios
Creators: name: De Melo, FE
Publisher: name: University of Liverpool Repository
Year: 2018

description: A series of methods for solving the multi-object estimation problem in the context sequential Bayesian inference is presented. These methods concentrate on dealing with challenging scenarios of multiple target tracking, involving fundamental problems of nonlinearity and non-Gaussianity of processes, high state dimensionality, high number of targets, statistical dependence between target states, and degenerate cases of low signal-to-noise ratio, high uncertainty, lowly observable states or uninformative observations. These difficulties pose obstacles to most practical multi-object inference problems, lying at the heart of the shortcomings reported for state-of-the-art methods, and so elicit novel treatments to enable tackling a broader class of real problems. The novel algorithms offered as solutions in this dissertation address such challenges by acting on the root causes of the associated problems. Often this involves essential dilemmas commonly manifested in Statistics and Decision Theory, such as trading off estimation accuracy with algorithm complexity, soft versus hard decision, generality versus tractability, conciseness versus interpretativeness etc. All proposed algorithms constitute stochastic filters, each of which is formulated to address specific aspects of the challenges at hand while offering tools to achieve judicious compromises in the aforementioned dilemmas. Two of the filters address the weight degeneracy observed in sequential Monte Carlo filters, particularly for nonlinear processes. One of these filters is designed for nonlinear non-Gaussian high-dimensional problems, delivering representativeness of the uncertainty in high-dimensional states while mitigating part of the inaccuracies that arise from the curse of dimensionality. This filter is shown to cope well with scenarios of multimodality, high state uncertainty, uninformative observations and high number of false alarms. A multi-object filter deals with the problem of considering dependencies between target states in a way that is scalable to a large number of targets, by resorting to probabilistic graphical structures. Another multi-object filter treats the problem of reducing the computational complexity of a state-of-the-art cardinalized filter to deal with a large number of targets, without compromising accuracy significantly. Finally, a framework for associating measurements across observation sessions for scenarios of low state observability is proposed, with application to an important Space Surveillance task: cataloging of space debris in the geosynchronous/geostationary belt. The devised methods treat the considered challenges by bringing about rather general questions, and provide not only principled solutions but also analyzes the essence of the investigated problems, extrapolating the implemented techniques to a wider spectrum of similar problems in Signal Processing.

Half of the participants were given the intervention of SIPPS, while the other half received Repeated Readings over the course of six weeks. While participants increased in their oral reading fluency rate, the hypothesis was supported for this study as there was no significant difference when looking at the pre- and post-test between strategies used. Research in this area should continue as there is little information on strategies other than Repeated Reading to help intermediate students increase their fluency rates.

description: Many natural and physical processes display long memory and extreme events. In these systems, the measured time series is invariably contaminated by noise. As the extreme events display large deviation from the mean behaviour, the noise does not affect the extreme events as much as it affects the typical values. Since the extreme events also carry the information about correlations in the full time series, they can be used to infer the correlation properties of the latter. In this work, from a given time series, we construct three modified time series using only the extreme events. It is shown that the correlations in the original time series and in the modified time series, as measured by the exponent obtained from detrended fluctuation analysis technique, are related to each other. Hence, the correlation exponents for a long memory time series can be inferred from its extreme events alone. This approach is demonstrated for several empirical time series.

The Effects of Repeated Reading on Struggling Third Grade Readers Reading Comprehension

Subjects: subject: Repeated reading
subject: Reading comprehension
subject: Third grade readers
subject: Education -- Research papers (Graduate)

description: The purpose of this study was to determine the impact of the strategy of repeated reading on the
reading comprehension of struggling third grade students. This study was quasi-experimental
with a pretest and posttest comparing the comprehension scores of the experimental group to the
control group of third grade students. Students were randomly chosen based on their small group
instructional groups, and their Fountas and Pinnell (F&P) comprehension score. Both groups
used the same materials in small group and whole group instruction. The experimental group of
13 students were guided in small group instruction using the repeated reading strategy over the
course of eight weeks. The control group of 12 students did not receive additional instruction.
Comparison of the pretest and the posttest scores showed no significant difference to suggest that
repeated reading is a strategy that would increase reading comprehension among struggling third
grade readers. Although the scores did not show significant differences, observations of the
experimental group and research suggest that teaching students through the repeated reading
strategy can be beneficial to student’s motivation in reading.
The Effect of a Multisensory Approach on Increasing Sight Word Automaticity in First Grade Students

Subjects: subject: Sight words
subject: Multisensory approach
subject: Education -- Research papers (Graduate)

description: The purpose of this study was to determine if the use of a multisensory approach would
impact the sight word automaticity of first grade students. The study consisted of a
sample of three first grade students who received instruction of sight words through
multisensory activities over a seven week time period. The measurement tool was the
Dolch word list for the primer and first grade levels. This study involved the use of a
pretest/posttest design to compare data before the intervention was administered and after
the intervention was complete. The null hypothesis was supported because the students
did not make statistically significant gains in sight word automaticity. Further research
should continue in order to determine best practices for developing word automaticity
and reading skills in primary students.
Time-Optimal Self-Stabilizing Leader Election on Rings in Population Protocols

description: We propose a self-stabilizing leader election protocol on directed rings in the model of population protocols. Given an upper bound $N$ on the population size $n$, the proposed protocol elects a unique leader within $O(nN)$ expected steps starting from any configuration and uses $O(N)$ states. This convergence time is optimal if a given upper bound $N$ is asymptotically tight, i.e., $N=O(n)$.

description: Evaluation and excavation at Buryfield, Bury, revealed evidence of a settlement dating from the Early to Mid-Roman period. Two successive large rectilinear agricultural enclosures were excavated. The pottery assemblage from the site indicates that the people who farmed this land were relatively affluent, and that the farmsteads they lived in may have been associated with, or have been part of, a villa estate situated within easy reach of Godmanchester (Durovigutum), eight miles to the south-west. A Middle Iron Age ditch was the only feature to clearly pre-date the Roman activity. Modern activity comprised the remains of two anti-aircraft searchlight batteries situated to the south-east of nearby Upwood Airfield, an important airbase during World War II.
Associations of water and methanol masers at milli-arcsec angular resolution in two high-mass young stellar objects

description: Most previous high-angular (<0.1 arcsec) resolution studies of molecular masers in high-mass star forming regions (SFRs) have concentrated mainly on either water or methanol masers. While high-angular resolution observations have clarified that water masers originate from shocks associated with protostellar jets, different environments have been proposed in several sources to explain the origin of methanol masers. Tha aim of the paper is to investigate the nature of the methanol maser birthplace in SFRs and the association between the water and methanol maser emission in the same young stellar object. We have conducted phase-reference Very Long Baseline Interferometry (VLBI) observations of water and methanol masers toward two high-mass SFRs, Sh 2-255 IR and AFGL 5142. In Sh 2-255 IR water masers are aligned along a direction close to the orientation of the molecular outflow observed on angular scales of 1-10 arcsec, tracing possibly the disk-wind emerging from the disk atmosphere. In AFGL 5142 water masers trace expansion at the base of a protostellar jet, whilst methanol masers are more probably tracing infalling than outflowing gas. The results for AFGL 5142 suggest that water and methanol masers trace different kinematic structures in the circumstellar gas.

description: We settle several questions regarding the model theory of Nakano spaces left open by the PhD thesis of Pedro Poitevin \cite{Poitevin:PhD}. We start by studying isometric Banach lattice embeddings of Nakano spaces, showing that in dimension two and above such embeddings have a particularly simple and rigid form. We use this to show show that in the Banach lattice language the modular functional is definable and that complete theories of atomless Nakano spaces are model complete. We also show that up to arbitrarily small perturbations of the exponent Nakano spaces are $\aleph_0$-categorical and $\aleph_0$-stable. In particular they are stable.

description: Monitoring and recording at 6-18 King Street during construction of new buildings for Christ's College, identified c. 11th-century gravel extraction pits containing Thetford, St Neots and Stamford ware pottery. The site adds to the picture of late Saxon-early medieval land use on this eastern fringe of the developing town at Cambridge, outside the line of the 12th-century King's Ditch. Pits and building remains dating from the 16th century onwards were also recorded.
title: Analysing Large-scale Surveillance Video

description: Analysing large-scale surveillance video has drawn signi cant attention because drone technology and high-resolution sensors are rapidly improving. The mobility of drones makes it possible to monitor a broad range of the environment, but it introduces a more di cult problem of identifying the objects of interest. This thesis aims to detect the moving objects (mostly vehicles) using the idea of background subtraction. Building a decent background is the key to success during the process. We consider two categories of surveillance videos in this thesis: when the scene is at and when pronounced parallax exists. After reviewing several global motion estimation approaches, we propose a novel cost function, the log-likelihood of the student t-distribution, to estimate the background motion between two frames. The proposed idea enables the estimation process to be e cient and robust with auto-generated parameters. Since the particle lter is useful in various subjects, it is investigated in this thesis. An improvement to particle lters, combining near-optimal proposal and Rao-Blackwellisation, is discussed to increase the e ciency when dealing with non-linear problems. Such improvement is used to solve visual simultaneous localisation and mapping (SLAM) problems and we call it RB2-PF. Its superiority is evident in both simulations of 2D SLAM and real datasets of visual odometry problems. Finally, RB2-PF based visual odometry is the key component to detect moving objects from surveillance videos with pronounced parallax. The idea is to consider multiple planes in the scene to improve the background motion estimation. Experiments have shown that false alarms signi cantly reduced. With the landmark information, a ground plane can be worked out. A near-constant velocity model can be applied after mapping the detections on the ground plane regardless of the position and orientation of the camera. All the detection results are nally processed by a multi-target tracker, the Gaussian mixture probabilistic hypothesis density (GM-PHD) lter, to generate tracks.
