title: To What Extent Are UK Companies Using Big Data to Inform Their Marketing Strategy?
Creators: name: Brewis, Claire Catherine Read
Publisher: name: The Open University
Year: 2016

description: With the development of computing hardware and software and the emergence of the internet there has been an explosion in the amount of information available to businesses. This information has been described as 'Big Data' reflecting its large variety, volume and velocity. Companies can use selected elements of this data to improve their knowledge of their customers and develop appropriate marketing strategies to respond to them. The study uses a social constructionist approach to develop a theory of how firms are applying Big Data to inform marketing strategy. It uses a qualitative approach to develop the theory. Semi structured interviews are used to gather insights from senior managers, with experience of their firms use of Big Data to inform marketing strategy. The participants emphasised using data to inform operational marketing strategy, such as, product development and promotion rather than higher level marketing strategy. They described using more and different data to inform their strategy. However firms were not responding to the velocity of data nor concerned with its veracity. Only one participant firm used data that complied with the definition of 'Big Data'. The challenges to firms in using Big Data were predominantly people-related. In particular firms benefited from engaged Executives to enable data-driven strategy. Progress in using data to inform marketing strategy was impeded by limited analytical capability. The skills and experience required to advance analytical capability were thought to be in short supply. The study responds to a gap in academic literature on the role of Big Data in marketing strategy, using primary data from seven UK companies across a range of industry sectors. It identifies a limited uptake of Big Data to inform marketing strategy however it highlights that the participating companies recognise Big Data as relevant to developing marketing insights, creating segmentation approaches and informing the marketing mix. The research proposes that a future study could examine the ways in which Big Data influences the development of marketing strategy with a more extensive participant group. The research could identify the degree to which participants' application of Big Data varies according to their sophistication of understanding of it. This could enable firms to identify the potential for higher levels of understanding and application of Big Data in developing their marketing strategy.

description: This paper tells, from a Cumbrian perspective, the story of the Klondike Gold Rush in what is now Canada's Yukon Territory. It describes how overnight the name Klondike, and its association with gold and untold riches, fired the imagination of the people of Cumbria and led to its rapid assimilation into Cumbrian culture. The word was widely used locally to name prize animals, machines, ships, mines, societies and places, and featured as a theme in many songs, stories, advertisements, plays, and pageants. More significantly it induced many Cumbrians from many walks of life to cross the Atlantic and seek their fortunes in the gold fields. Their experiences, successes and failures are here described from contemporary sources and letters.

description: The brain processes many aspects of the visual world separately and in parallel, yet we perceive a unified world populated by objects. In order to create such a bound percept, the visual system must construct object-centered representations out of separate features and then maintain the representations across changes in space and time. Here, we examine the role of features themselves in maintaining and disambiguating the representations of the objects to which they belong. In three experiments, we measure how the perceived motion of two objects traversing ambiguous trajectories is affected by the contrast between the features and surrounding fields, by the contrast between features, and by changes to orientation of texture within objects. We report that the maintenance and disambiguation of object representations depend on the contrast of the features relative to their surrounds and on the extent of feature differences between the two objects. These feature dependencies indicate that object representation relies on relative response to many stimulus dimensions.

title: Studies of Physical Properties on the Performance of Novel Recognition Polymers
Creators: name: Brahmbhatt, Heli A.
Publisher: name: The Open University
Year: 2016

description: Selective interactions occurring between antigen and antibody have been studied intensively for developing bio-sensing platforms, however antibodies suffer from shorter shelf-life and high cost of production. Molecularly Imprinted Polymers (MIPs) on the other hand have drawn huge attention as antibody analogs for their advantages over natural antibodies. Increased research undertaken in this area for over two decades has made it possible to develop MIP nanoparticles that are currently dubbed as the most suitable alternatives to natural antibodies. MIP preparation is cost-effective and also offers flexibility in developing different polymer formats by different methods. However, the resulting MIPs are found to be considerably different due to different experimental variables associated with different methods. This has been one of the biggest challenges in developing MIPs for commercial applications in spite of their excellent recognition performances shown in lab experiments. To this end, the research undertaken in this project has been executed by performing three case studies where novel recognition polymers have been prepared in different experimental conditions and different formats. Particularly, the study of physical properties of the polymers and their influence on their analyte recognition performance is at the heart of all three case studies performed during this project. The study presented in Chapter 3 has investigated microwave reactor led thermal polymerisation as a potential alternative method for the preparation of MIP monoliths, whereas the study presented in Chapter 4 has investigated into developing novel polymers as potential recognition materials for ToxiQuant technique which is used for mycotoxin detection. The study presented in Chapter 5 proposes a novel approach for the development of MIP nanoparticles for selective oligonucleotide recognition. The prepared polymers have been analysed for their physical properties (such as, surface area, particle size, zeta potential, cross-linking degree, pore volume, thermal stability) and analyte recognition performance. The obtained results strongly recommend that the experimental parameters used for polymerisations are well reflected in the physical make of the resulting polymers and have further consequences on their analyte recognition performance. Study of the physicochemical properties of the polymers and their underlying causes may help in developing more consistent, predictable and selective recognition polymer materials.

description: We present high resolution two dimensional velocity fields from integral field spectroscopy along with derived rotation curves for nine low surface brightness galaxies. This is a positive step forward in terms of both data quality and number of objects studied. We fit NFW and pseudo-isothermal halo models to the observations. We find that the pseudo-isothermal halo better represents the data in most cases than the NFW halo, as the resulting concentrations are lower than would be expected for LCDM.

description: Hydrogen is the lightest element and the most abundant element in the universe. It is very flammable due to being reactive. Hydrogen is an essential element in life. It is present in water and in almost all the molecules in living things. It is also used to remove sulfur from fuel during the oil-refining process. Hydrogen is mainly found in many organic compounds such as the hydrocarbons that make up many of our fuels like gasoline, natural gas, propane or methanol.
In today’s life, people usually need fuel to travel everywhere because it is necessary to make a vehicle start. Some scientists start to think of a good alternative to make an eco-friendly fuel and help our planet in one of the problems the world is facing. Researchers are trying to invent a machine that could help them prove that hydrogen is actually effective as a fuel and they are trying to use different methods to get a good supply of hydrogen to use in their experiment. Hydrogen is a good element to make an eco-friendly fuel.
Scale-invariance in brightness illusions implicates object-level visual processing

Publisher: name: American University
Year: 2023

description: Brightness illusions demonstrate that an object's perceived brightness depends on its visual context, leading to theoretical explanations ranging from simple lateral inhibition to those based on the influence of knowledge of and experience with the world. We measure the relative brightness of mid-luminance test disks embedded in gray-scale images, and show that rankings of test disk brightness are independent of viewing distance, implying that the rankings depend on the physical object size, not the size of disks subtended on the retina. A single filter that removes low spatial frequency content, adjusted to the diameters of the test disks, can account for the relative brightness of the disks. We note that the removal of low spatial frequency content is a principle common to many different approaches to brightness/lightness phenomena; furthermore, object-size representations--as opposed to retinal-size representations--inherently remove low spatial frequency content, therefore, any process that creates object representations should also produce brightness illusions.

description: We present the optical properties of \na single crystals, measured over a broad spectral range as a function of temperature ($T$). The capability to cover the energy range from the far-infrared up to the ultraviolet allows us to perform reliable Kramers-Kronig transformation, in order to obtain the absorption spectrum (i.e., the complex optical conductivity). To the complex optical conductivity we apply the generalized Drude model, extracting the frequency dependence of the scattering rate ($Γ$) and effective mass ($m^*$) of the itinerant charge carriers. We find that $Γ(ω)\sim ω$ at low temperatures and for $ω> T$. This suggests that \na is at the verge of a spin-density-wave metallic phase.

The material is an S = 2 antiferromagnetic linear chain that undergoes long-range ordering to a canted antiferromagnetic state at 23 K. The comparison of magnetic data from polycrystalline samples with the results of specific heat measurements using a pressed pellet of powder reveals the importance of the length of the chains in the sample in relation to the magnetic correlation length.

description: The contrast asynchrony is a stimulus configuration that illustrates the visual system's separable responses to luminance and luminance contrast information (Shapiro, 2008; Shapiro et al., 2004). When two disks, whose luminances modulate in phase with each other, are each surrounded by a disk, one light and one dark, observers can see both the in-phase brightness signals and the antiphase contrast signals and can separate the two. Here we present the results of experiments in which observers viewed a similar stimulus dichoptically. We report that no asynchrony is perceived when one eye is presented with modulating disks and the other eye is presented with the black and white surround rings, nor is an asynchrony perceived in gradient versions of the contrast asynchrony. We also explore the window shade illusion (Shapiro, Charles, & Shear-Heyman, 2005) dichoptically and find that when a modulating disk is presented to one eye and a horizontally split black/white annulus is presented to the other, observers perceive a shading motion up and down the disk. This shading can be seen in either direction in the binocular condition, but it is almost always seen as moving towards low contrast in the monocular condition. These findings indicate the presence of separable retinal and cortical networks for contrast processing at different temporal and spatial scales.

Year: 2020
Subjects: subject: Information Retrieval (cs.IR)

description: Collaborative Filtering is largely applied to personalize item recommendation but its performance is affected by the sparsity of rating data. In order to address this issue, recent systems have been developed to improve recommendation by extracting latent factors from the rating matrices, or by exploiting trust relations established among users in social networks. In this work, we are interested in evaluating whether other sources of preference information than ratings and social ties can be used to improve recommendation performance. Specifically, we aim at testing whether the integration of frequently co-occurring interests in information search logs can improve recommendation performance in User-to-User Collaborative Filtering (U2UCF). For this purpose, we propose the Extended Category-based Collaborative Filtering (ECCF) recommender, which enriches category-based user profiles derived from the analysis of rating behavior with data categories that are frequently searched together by people in search sessions. We test our model using a big rating dataset and a log of a largely used search engine to extract the co-occurrence of interests. The experiments show that ECCF outperforms U2UCF and category-based collaborative recommendation in accuracy, MRR, diversity of recommendations and user coverage. Moreover, it outperforms the SVD++ Matrix Factorization algorithm in accuracy and diversity of recommendation lists.

description: This paper examines the diminishing use of univariate analysis in investment and other managerial decisions in Bangladesh. It aimed at determining the extent new generation managers use financial ratios for corporate decisions, reasons for declining use of ratios, understand the current resorts and effects of these diminishing use on corporate wellbeing over the last five years. Twenty corporate bodies were surveyed and two hundred questionnaires were administered to three segments of respondents comprising of Chief Executives & Senior managements, Accounting/Finance Officers and Outside Corporate Stakeholders. It was discovered that the use of financial ratios in many managerial and other investment decisions are significantly diminished in Bangladesh, however there is no significant managerial resorts but there exists significant effect of diminishing use of univariate discriminant analysis on the corporate wellbeing for the last five years. We recommend that the research be carried out on international scale to enable more accurate generalizations.

description: The counter-intuitive phenomenon of pressure-induced softening in materials is likely to be caused by the same dynamical behaviour that produces negative thermal expansion. Through a combination of molecular dynamics simulation on an idealised model and neutron diffraction at variable temperature and pressure, we show the existence of extraordinary and unprecedented pressure-induced softening in the negative thermal expansion material scandium fluoride, ScF$_3$, with values of the pressure-derivative of the bulk modulus $B$, $B^\prime = \partial B / \partial P$, reaching as low as $-40 \pm 1$.

description: We present the results of a partially quenched lattice QCD calculation of light quark masses with $N_f=2$ degenerate dynamical flavors. Numerical simulations are carried out using the plaquette gauge action and the Wilson quark action at $β= 5.8$ ($a^{-1} \simeq 3.2\gev$). The spatial extension of the $24^3 \times 48$ lattice is about 1.5 fm. Configurations have been generated at four values of the sea quark masses, for which the ratio of pseudoscalar over vector meson masses is in the range $M_P/M_V \simeq 0.60 ÷0.75$. An important feature of the present study is the use of non-perturbative renormalization, performed with the $\ri$ method. The effects of dynamical sea quarks in the determination of light quark masses have been investigated by performing a quenched calculation on a similar lattice. Our results for the average up-down and strange quark masses are $m_{ud}^{MS} (2\gev) = 4.3(4) (^{+1.1}_{-0.4})\mev$ and $m_s^{MS}(2\gev)=101(8)(^{+25}_{-9}) \mev$. These values are larger than those obtained by evaluating the quark mass renormalization constants with one-loop (boosted) perturbation theory. Our results for the light quark masses are compatible with those obtained in the quenched simulation. No significant sea quark effects are seen, at the values of sea quark masses used in the present study.

description: Cyber-Physical Systems (CPSs) are vastly used in today's cities critical infrastructure. The cyber part of these systems usually has a network component through which cyber attacks can be launched. In this paper, we first design an intrusion detection system (IDS) by identifying the plant. We assume the initial operation period of the CPS is attack-free and learn the plant model. Then, we compare the expected output found via the identifier with the real one coming through the feedback link. Any difference greater than a threshold is deemed to be an anomaly. To compensate, once the IDS flags a change in the loop, we restart the system identification to find the new transfer function. With the estimation of the new transfer function at hand, a new controller is designed to keep the system stable. To test the idea, we took a DC motor as the plant and employed ARX identifier. MATLAB Simulink environment was used to test the proposed intrusion detection and compensation framework. We applied a set of deception attacks to the forward channel in our experiments. The obtained results prove that our detection strategy works well and timely reacts to anomalies. Moreover, they show that the compensation strategy is also effective and keeps the system stable under such attacks.

description: The contrast asynchrony is a stimulus configuration that illustrates the visual system's separable responses to luminance and luminance contrast information (Shapiro, 2008; Shapiro et al., 2004). When two disks, whose luminances modulate in phase with each other, are each surrounded by a disk, one light and one dark, observers can see both the in-phase brightness signals and the antiphase contrast signals and can separate the two. Here we present the results of experiments in which observers viewed a similar stimulus dichoptically. We report that no asynchrony is perceived when one eye is presented with modulating disks and the other eye is presented with the black and white surround rings, nor is an asynchrony perceived in gradient versions of the contrast asynchrony. We also explore the window shade illusion (Shapiro, Charles, & Shear-Heyman, 2005) dichoptically and find that when a modulating disk is presented to one eye and a horizontally split black/white annulus is presented to the other, observers perceive a shading motion up and down the disk. This shading can be seen in either direction in the binocular condition, but it is almost always seen as moving towards low contrast in the monocular condition. These findings indicate the presence of separable retinal and cortical networks for contrast processing at different temporal and spatial scales.

description: Background: The human visual system does not treat all parts of an image equally: the central segments of an image, which fall on the fovea, are processed with a higher resolution than the segments that fall in the visual periphery. Even though the differences between foveal and peripheral resolution are large, these differences do not usually disrupt our perception of seamless visual space. Here we examine a motion stimulus in which the shift from foveal to peripheral viewing creates a dramatic spatial/temporal discontinuity. Methodology/Principal Findings: The stimulus consists of a descending disk (global motion) with an internal moving grating (local motion). When observers view the disk centrally, they perceive both global and local motion (i.e., observers see the disk’s vertical descent and the internal spinning). When observers view the disk peripherally, the internal portion appears stationary, and the disk appears to descend at an angle. The angle of perceived descent increases as the observer views the stimulus from further in the periphery. We examine the first- and second-order information content in the display with the use of a three-dimensional Fourier analysis and show how our results can be used to describe perceived spatial/ temporal discontinuities in real-world situations. Conclusions/Significance: The perceived shift of the disk’s direction in the periphery is consistent with a model in which foveal processing separates first- and second-order motion information while peripheral processing integrates first- and second-order motion information. We argue that the perceived distortion may influence real-world visual observations. To this end, we present a hypothesis and analysis of the perception of the curveball and rising fastball in the sport of baseball. The curveball is a physically measurable phenomenon: the imbalance of forces created by the ball’s spin causes the ball to deviate from a straight line and to follow a smooth parabolic path. However, the curveball is also a perceptual puzzle because batters often report that the flight of the ball undergoes a dramatic and nearly discontinuous shift in position as the ball nears home plate. We suggest that the perception of a discontinuous shift in position results from differences between foveal and peripheral processing.

description: Iterative Closest Point (ICP) solves the rigid point cloud registration problem iteratively in two steps: (1) make hard assignments of spatially closest point correspondences, and then (2) find the least-squares rigid transformation. The hard assignments of closest point correspondences based on spatial distances are sensitive to the initial rigid transformation and noisy/outlier points, which often cause ICP to converge to wrong local minima. In this paper, we propose the RPM-Net -- a less sensitive to initialization and more robust deep learning-based approach for rigid point cloud registration. To this end, our network uses the differentiable Sinkhorn layer and annealing to get soft assignments of point correspondences from hybrid features learned from both spatial coordinates and local geometry. To further improve registration performance, we introduce a secondary network to predict optimal annealing parameters. Unlike some existing methods, our RPM-Net handles missing correspondences and point clouds with partial visibility. Experimental results show that our RPM-Net achieves state-of-the-art performance compared to existing non-deep learning and recent deep learning methods.

description: We study exact renormalisation group equations for the 3d Ising universality class. At the Wilson-Fisher fixed point, symmetric and antisymmetric correction-to-scaling exponents are computed with high accuracy for an optimised cutoff to leading order in the derivative expansion. Further results are derived for other cutoffs including smooth, sharp and background field cutoffs. An estimate for higher order corrections is given as well. We establish that the leading antisymmetric corrections to scaling are strongly subleading compared to the leading symmetric ones.

description: Using data from seven cohorts of language immersion lottery applicants in a large, urban school district, we estimate the causal effects of immersion programs on students’ test scores in reading, mathematics, and science and on English learners’ (EL) reclassification. We estimate positive intent-to-treat (ITT) effects on reading performance in fifth and eighth grades, ranging from 13% to 22% of a standard deviation, reflecting 7 to 9 months of learning. We find little benefit in terms of mathematics and science performance but also no detriment. By sixth and seventh grade, lottery winners’ probabilities of remaining classified as EL are 3 to 4 percentage points lower than those of their counterparts. This effect is stronger for ELs whose native language matches the partner language.

description: Textual queries are largely employed in information retrieval to let users specify search goals in a natural way. However, differences in user and system terminologies can challenge the identification of the user's information needs, and thus the generation of relevant results. We argue that the explicit management of ontological knowledge, and of the meaning of concepts (by integrating linguistic and encyclopedic knowledge in the system ontology), can improve the analysis of search queries, because it enables a flexible identification of the topics the user is searching for, regardless of the adopted vocabulary. This paper proposes an information retrieval support model based on semantic concept identification. Starting from the recognition of the ontology concepts that the search query refers to, this model exploits the qualifiers specified in the query to select information items on the basis of possibly fine-grained features. Moreover, it supports query expansion and reformulation by suggesting the exploration of semantically similar concepts, as well as of concepts related to those referred in the query through thematic relations. A test on a data-set collected using the OnToMap Participatory GIS has shown that this approach provides accurate results.
