title: An Investigation into the Effect that Technology had on the Strategies of J. Sainsbury plc, Tesco plc and Safeway plc: With a Particular Focus on the Period 1980 to 1990
Creators: name: Morgan, Chris
Publisher: name: The Open University
Year: 1998

description: This research is focused on three food multiple retailers, Sainsbury plc, Tesco plc, and Safeway plc. The research is designed to explore the relationship between technology and strategy in these organisations. The currently held view among the researchers and managers of these organisations is that technology has a limited impact on the processes that formulate strategy, and as such may be regarded as having an enabling role. This thesis proposes that while this view may have been correct in the past it is so no longer, and that technology is not following strategy but leading strategy in the food retailers examined. In order to confirm this thesis the history, technical development and technical structure of the three retailers was investigated. The results of this research was subsequently analysed and the following conclusions were made: a. Technology has a much greater inq)act on the strategy of multiple food retailers than has been previously thought. Technology defines the boundaries of operational activities, and, through controlling a substantial proportion of the information that managers use in the strategy making process, technology de facto if not de jure greatly influences the retailers strategies, and in some cases may actually lead them. b. The food multiples, in not appreciating the extent to which their fate is tied up with the information technology they are using, are foiling to educate and train the general management of the organisations technologically. c. Technological progress is widening the gap between the general management and technical management, and in the long run this will cause serious strategic problems unless this gap is closed through positive action.

description: The hard X-ray spectral index of some AGN has been observed to steepen with the source flux. This has been interpreted in a Comptonization scenario, where an increase in the soft flux decreases the temperature of the corona, leading to steepening of the photon index. However, the variation of the coronal temperature with flux has been difficult to measure due to the presence of complex reflection component in the hard X-rays and the lack of high-quality data at that energy band. Recently, a 200 ks {\it NuSTAR} observation of Ark 564 in 3--50 keV band, revealed the presence of one of the coolest coronae with temperature $kT_e \sim 15$ keV in the time-averaged spectrum. Here, we re-analyse the data and examined the spectra in four flux levels. Our analysis shows that the coronal temperature decreased from $\sim 17$ to $\sim 14$ keV as the flux increased. The high energy photon index $Γ\sim 2.3$ varied by less than $0.1$, implying that the optical depth of the corona increased by about 10\% as the flux increased. This first reporting of coronal temperature variation with flux shows that further long observation by {\it NuSTAR} of this and other sources would shed light on the geometry and dynamics of the inner regions of the accretion flow.

description: A hierarchy of integrable hamiltonian nonlinear ODEs is associated with any decomposition of the Lie algebra of Laurent series with coefficients being elements of a semi-simple Lie algebra into a sum of the subalgebra consisting of the Taylor series and some complementary subalgebra. In the case of the Lie algebra $so(3)$ our scheme covers all classical integrable cases in the Kirchhoff problem of the motion of a rigid body in an ideal fluid. Moreover, the construction allows us to generate integrable deformations for known integrable models.

description: We discuss the importance of including baryons in analyses of unified dark matter scenarios, focusing on toy models involving a generalized Chaplygin gas. We determine observational constraints on this unified dark matter scenario coming from large scale structure, type Ia Supernovae and CMB data showing how this component can bring about a different behaviour from classical $Λ$CDM and thus motivate further studies of this type of models. We also speculate on interesting new features which are likely to be important on non-linear scales in this context.

Kommt prospektiven Eltern eine moralische Verantwortung für die Umsetzbarkeit ihrer reproduktiven Freiheit zu?
title: An Ecological Study of Colliery Waste and an Evaluation of the Role of Earthworms in its Reclamation.
Creators: name: Pearson, Frank
Publisher: name: The Open University
Year: 1998

description: A study of the earthworm populations of a naturalised deep mined coal spoil heap was undertaken. After an initial survey of the site, the history of the tip was researched to provide background for the present condition of the area. Documentary evidence, largely in the form of maps, suggested that tipping probably ceased in or shortly after 1920, and part of the tip was altered in 1960 due to roadworks.

 The physical and chemical parameters of the incipient soil were examined, using standard MAFF soil testing methods, which showed that the tip contained some plant nutrients but was mainly clay and had a low pH over most of the area. By means of plant surveys over three years, the vegetation cover was shown to reflect the change in composition of the spoil over the site.

 The worm populations present in the vegetated parts of the heap were in sharp contrast to their absence in the nearby bare areas which had a lower pH. The low pH was attributed to the acid produced by the oxidation of the pyrite present in the spoil. On the altered part of the tip, pH was neutral.

 Methods of ameliorating the spoil from the bare parts of the tip were assessed through experiments using Eisenia fetida and various nutrients, both with and without lime addition. These experimental trials were undertaken in plastic cylinders, which afforded the opportunity of regular inspection and photographic records of the activities of the worms and their products.

 Results, under laboratory conditions, indicate that it is possible to ameliorate both the texture and low pH of weathered colliery spoil, by the application of Eisenia fetida in vegetable matter.

description: A comprehensive, temporal and spatiotemporal linear stability analyses of a (driven) Oldroyd-B fluid with Poiseuille base flow profile in a horizontally aligned, square, Hele-Shaw cell is reported to identify the viable regions of topological transition of the advancing interface. The dimensionless groups governing stability are the Reynolds number, $Re = \frac{b^2 ρ\mathcal{U}_0}{12 η_0 L}$, the elasticity number, $E = \frac{12 λ(1-ν)η_0}{ρb^2}$ and the ratio of solvent to polymer solution viscosity, $ν= \frac{η_s}{η_0}$; here $b$ is the cell gap, $L$ is the length/width of the cell, $\mathcal{U}_0$ is the maximum velocity of the mean flow, $ρ$ is the density of the driven fluid and $λ$ is the relaxation time. Excellent agreement on the size of the relative finger width between our model and the experiments in the Stokes and the inertial, Newtonian regime is found. In the asymptotic limit $E(1-ν) \ll 1$, the critical Reynolds number, $Re_c$ (defined as the largest Reynolds number beyond which all wavenumbers are temporally unstable) diverges as per the scaling law $Re_c \sim \left[E(1-ν)\right]^{-5/3}$ and the critical wavenumber increases as $α_c \sim \left[E(1-ν)\right]^{-2/3}$. The temporal stability analysis stipulate that (a) the destabilizing influence of the inertial, (b) the destabilizing impact of finite boundaries near the wall, and (c) the stabilizing (destabilizing) impact of elasticity combined with low (high) fluid inertia . The Briggs idea of analytic continuation is deployed to classify regions of absolute and convective instabilities, as well as the evanescent modes. The phase diagram reveals the presence of absolutely unstable region at high values of Reynolds and elasticity number, confirming the role of fluid inertia in triggering a pinch-off.

description: This study investigated the thermal performance of energy active windows (EAW). Theobtained U-values of the studied EAW were compared to state-of-the-art triple-glazingwindows (TGW) during a heating season. Simulation software, Matlab, was used foranalytical heat transfer modeling of the studied window- types and to illustrate temperaturegradients across the windows. The main objective was to evaluate how lower U-values duringthe coldest winter hours can be achieved to potentially shift peak heating loads of buildings.Generally, it was shown that the EAW had lower U-values compared to conventional TGW. Itis concluded that windows, which have always been considered as a heat sink in constructions,can maintain building energy requirements while improving the indoor environment quality,the aesthetics, and natural lighting in buildings if replaced by EAW.

description: In this study, we investigate whether the trade in sh and sh prod- ucts contributed to the decline of 57 sh species observed from 1996 to 2009 in Turkey. Our aim is to test the theoretical prediction that trade liberalization in the presence of open access resources can lead to a re- duction in harvest at the long-run due to stock depletion. To this end, we carry out an instrumental variable estimation for a panel data model. Estimation results reveal that the harvest supply curve bends backward, i.e., the resource is overexploited, no matter if the sh is exported or not.

description: This study aims to identify the relationship between underpricing and long-term market performance of IPOs in the Indonesian Stock Exchange (IDX), as well as determinants of IPOs' market performance. We based our paper on the idea that it is more meaningful and relevant to investigate underpricing and long-term market performance determinants at different distribution points. OLS and quantile regression analysis is applied to 105 samples of IPOs during 2009-2013. The results of OLS and quantile regressions indicate that assets value, age, proceeds, and underwriters’ reputation are determinants of long-term market performance; while assets, age and proceeds also become underpricing determinants. Among these factors, proceeds become the most important determinant of underpricing and long-term market performance.

description: This paper does not set out to redefine and re-explain the food security concept, but to look into the links between food security and international trade. First, we propose a conceptual framework to sum up the relationships between food security, international trade and public policies. Second, we check whether the widely used food security indicators are really suited to monitoring the impacts of government interventions and external trade shocks on the food security level. We use the Bonilla Index as our food security indicator throughout this analysis of the impact of national policies on food security.

description: We perform experiments with a granular system that consists of a collection of identical hollow spheres (ping-pong balls). Particles rest on a horizontal metallic grid and are confined within a circular region. Fluidization is achieved by means of a turbulent air current coming from below. Air flow is adjusted so that the balls do not elevate over the grid, as an approach to 2D dynamics. With a high-speed camera, we take images of the system. From these images we can infer horizontal particle positions and velocities by means of particle-tracking algorithms. With the obtained data we analyze: a) the systematic measurement error in the determination of positions and velocities from our digital images; b) the degree of homogeneity achieved in our experiments (which depends on possible deviations of the grid from the horizontal and on the homogeneity of turbulent air wakes). Interestingly, we have observed evidences of crystallization at high enough densities.

description: Food security is a major concern, especially for developing countries where a large percentage of population lives in rural areas and where agricultural sector represents an important weight in their economy. Agricultural and food imports play a particular key role in terms of food security in low income countries. Indeed, dependency on imports for food may raise a problem for food security in particular in the case of sudden price increase which put up national food bill. The national state of food availability combining food imports and domestic food production thus constitutes some crucial information. Following Diaz-Bonilla et al. (2000), this contribution aims to shed light on the determinants of food security at national level. We first build a theoretical framework linking explicitly food security measured by the Bonilla index and national intervention policy intervention in agriculture. Second, the empirical methodology aims at assessing the impact of national policy responses to 2008 price surge in terms of food security using the national rate assistance index on importable food products for 42 countries over the period 1995-2010. Our results suggest that most developing countries have largely used their possibility to play with the NRA level in order to moderate BI during the 2008 food price surge.

description: We present the first Doppler images of the prototypical active binary star RS CVn, derived from high-resolution spectra observed in 2004, 2016 and 2017, using three different telescopes and observing sites. We apply the least-squares deconvolution technique to all observed spectra to obtain high signal-to-noise line profiles, which are used to derive the surface images of the active K-type component. Our images show a complex spot pattern on the K star, distributed widely in longitude. All starspots revealed by our Doppler images are located below a latitude of about 70$^{\circ}$. In accordance with previous light-curve modeling studies, we find no indication of a polar spot on the K star. Using Doppler images derived from two consecutive rotational cycles, we estimate a surface differential rotation rate of $ΔΩ= -0.039 \pm 0.003 ~rad~d^{-1}$ and $α= ΔΩ/Ω_{eq} = -0.030 \pm 0.002$ for the K star. Given the limited phase coverage during those two rotations, the uncertainty of our differential rotation estimate is presumably higher.

description: The paper presents a simplified economic growth model with social capital, as an alternative for sustained long-term growth. The intuition behind the model suggests its application for developing economies that historically have focused their attention on the accumulation of physical capital and not on endogenous factors such as human capital and social capital. The model is considered as a Cobb-Douglas production function that includes three types of capital: physical, human and social. From the model, we obtain evidence from estimates for the Ecuadorian economy in the period 1980-2015, which underlie the main endogenous sources regarding physical capital. As a result, some policy implications are highlighted.

description: We study dispersive optical nonlinearities of short pulses propagating in high number density, warm atomic vapors where the laser resonantly excites atoms to Rydberg $P$-states via a single-photon transition. Three different regimes of the light-atom interaction, dominated by either Doppler broadening, Rydberg atom interactions, or decay due to thermal collisions between groundstate and Rydberg atoms, are described. We show that using fast Rabi flopping and strong Rydberg atom interactions, both in the order of gigahertz, can overcome the Doppler effect as well as collisional decay, leading to a sizable dispersive optical nonlinearity on nanosecond timescales. In this regime, self-induced transparency (SIT) emerges when areas of the nanosecond pulse are determined primarily by the Rydberg atom interaction, rather than the area theorem of interaction-free SIT. We identify, both numerically and analytically, the condition to realize Rydberg-SIT. Our study contributes to efforts in achieving quantum information processing using glass cell technologies.

description: We investigate a counterintuitive geometric interaction between defects and curvature in thin layers of superfluids, superconductors and liquid crystals deposited on curved surfaces. Each defect feels a geometric potential whose functional form is determined only by the shape of the surface, but whose sign and strength depend on the transformation properties of the order parameter. For superfluids and superconductors, the strength of this interaction is proportional to the square of the charge and causes all defects to be repelled (attracted) by regions of positive (negative) Gaussian curvature. For liquid crystals in the one elastic constant approximation, charges between 0 and $4π$ are attracted by regions of positive curvature while all other charges are repelled.

description: Brazil, China and U.S. play crucial roles in global food supply and demand system as consumers, producers, and traders. Therefore, any agricultural and environmental policy tool of these 3 countries deserve special attention since their policy environment contributes to farmers’ decisions to plant and consumers’ decisions to buy. In an era of growing demand pressures, it is more important than ever before to understand the impact of policies relevant to land and water resources. This study attempts to identify and analyze these dynamics for these 3 countries in a global context.

However, the highest concentration values of the Mango crop are in Ratnagiri taluka next to Rajapur, Mandangarh, Lanja, Chiplun, Sangameshwar, Dapoli, and lastly at Khed. The livelihood of people is significantly dependent on mango production. A major pest found in the study area is the Mango leafhopper. As per overseas reports, mango leafhopper affects more than another mango pest. Beneficial insects found at mango orchards during the survey are viz. red ants, spiders, ladybirds, butterflies, chrysopids, hoverflies, etc. The farmers used to destroy these useful insects due to by applying chemical pesticides. Frequently occurring diseases in the study area including Powdery mildew, Anthracnose on fruit, Bacterial leaf blight, sooty mould, Mango malformation, floral malformation, Dieback, etc. However, several mango pests observed in the study area during the cursory survey is Mango hopper, Stem borer, Fruit fly, Mealybug, Stone weevil, leaf-cutting weevils, shoot borer, leaf gall fly, leaf-eating caterpillar, Mango blossom midge, Red ants, Leaf Webber, mite, Mango scale insect, Bark eating Caterpillar, leaf-eating weevils, leaf miner, Mango aphid, etc. For sustainable mango production and to achieve the exportable quality of mango it is well felt need to adopt organic farming and integrated pest management practices at Ratnagiri district.

description: (Abridged) Low-luminosity, active star-forming blue compact galaxies (BCGs) are excellent laboratories for investigating the process of star formation on galactic scales and probing the interplay between massive stars and the surrounding interstellar (or intergalactic) medium. We investigated the morphology, structure, and stellar content of the Blue Compact Galaxy Mrk 900, combining optical integral field observations obtained with VIMOS at the VLT and deep broad-band photometry taken at the 2.5 m NOT telescope. From the integral field data, we built continuum, emission, and diagnostic line ratio maps and produced velocity and velocity dispersion maps. We also generated the integrated spectrum of the major HII regions and the nuclear area to determine reliable physical parameters and oxygen abundances. The broad-band data, tracing the galaxy up to radius 4 kpc, allowed us to investigate the properties of the low surface brightness underlying stellar host. We disentangle two different stellar components in Mrk 900: a young population, which resolves into individual stellar clusters with ages ~5.5-6.6 Myr and extends about 1 kpc along the galaxy minor axis, is placed on top of a rather red and regular shaped underlying stellar host, several Gyr old. We find evidence of a substantial amount of dust and an inhomogeneous extinction pattern, with a dust lane crossing the central starburst. Mrk 900 displays overall rotation, although distorted in the central, starburst regions; the dispersion velocity map is highly inhomogeneous, with values increasing up to 60 kms$^{-1}$ at the periphery of the SF regions, where we also find hints of the presence of shocks. Our observational results point to an interaction or merger with a low-mass object or infalling gas as plausible trigger mechanisms for the present starburst event.

title: Spontaneous mutagenesis in stressed Escherichia coli
Creators: name: Timms, Andrew Robert
Publisher: name: The Open University
Year: 1998

description: Mutation processes occurring in starving or stressed bacteria are different from those that are found in growing bacteria. The mutageitic response of E.coli to a number of different stress conditions, including amino acid starvation and challenge with the antibiotic streptomycin has been examined. In an E.coli trpA23 strain starved for tryptophan, the formation of small in-frame deletions was stimulated by the persistence of oxidatively damaged guanine and unrepaired mismatches in the DNA. Most (75%) of the deletions had direct repeats at each termini, one of which was lost in the deletion process. The deletions restored functionality to the product of the trpA gene enabling the mutants to form slow growing colonies on minimal plates lacking tryptophan.

 During starvation of an E.coli tyrA14 strain WU3610 for the amino acid tyrosine, a new phenotypic suppressor gene (tas) was isolated that specifically complemented the absence of prephenate dehydrogenase activity. The gene is necessary for the process of starvation-associated mutagenesis in this strain; mutants do not arise during starvation in a ray deletion strain.

 A high proportion (up to 20%) of ancillary mutations within the rpsL gene of E.coli have previously been found in newly arising streptomycin dependent mutants and have been shown to confer a selective advantage in established strains. This study shows that they also confer an advantage in mutants containing mixed wild type and streptomycin dependent ribosomes in the presence and absence of streptomycin. However, this selective advantage is still not enough to account for the rate at which these ancillary mutations are recovered and we need to assume a mutation rate of 10-3 to 10-4/gene/replication to explain the observed frequency.

subject: Debt portfolio, methods of optimization, model for developing a debt portfolio, target structure of capital, strategy for attracting loan capital

description: Goal : Although companies use actively the potentials of a debt capital market and debt financial instruments market to finance their activities, the development of company’s debt portfolio for the strategic perspective remains a relevant issue. The goal of this paper is to create a model for the development of the optimal debt portfolio aimed at implementing company’s corporate strategy. Methods: We have created an optimization model for creating company’s debt portfolio based on G. Markowitz’s portfolio theory within a framework of our research. To develop a target function, we have used the maximum contingent income from the attraction of loans. We have created a system of restrictions based on financial risks diversification. To implement the model, we have used the MS Excel environment and the packet of applied programs MathCAD Results: We have elaborated the model for creating company’s debt portfolio for the strategic perspective. We have chosen the maximization of contingent benefits of attracting loan capital from different sources of debt financing as a target criterion of the model. The model’s restrictions enable to diversify financial risks. They encompass the following terms: the achievement of the goal structure of capital, the provision of financial risks diversification in choosing the strategy for financing company’s assets; the optimization a financial leverage effect; the diversification of the risks of losing ability to pay and reducing financial stability. To analyze the possible utilization of the model, we have considered the development of the debt portfolio of a construction company, which provides the strategy for company’s development over the next 5 years. The results of the research have enabled to develop company’s optimal debt portfolio that complies with the terms of financial risks diversification and to define the optimal sources of loans at each moment of time. Conclusions: Our model for the development of company’s debt portfolio enables to model the structure of the sources of loan financing depending on the needs for loan capital at each moment of time and maximum amounts that a company may attract from each source of debt financing. Changes in the terms of granting loan capital and changes in the situation in product and financial markets may lead to structural shifts in the content of financing sources; therefore, the process of modelling the optimal structure of debt financing should be a continuous. The obtained results of modeling the structure of a debt portfolio enable a company to make more informed decisions in attracting loan financing.

description: The food price crisis in 2007/2008 created a sense of urgency to reconsider the challenge of how to feed an increasing population. A number of studies have addressed the demand for and supply of food in the long run using scenario analysis, often combined with model simulations. We compare twelve food security scenario studies that have been published between 2000 and present by analysing the assumptions about key drivers of food security as well as the range in key food security outcomes. We find that most scenarios can be classified using a set of scenario families with comparable assumptions and outcomes. That said, the majority of the scenarios only deal with two of the four dimensions of food security: food availability and food accessibility, largely ignoring food utilisation and stability. We also find that important drivers such as bio-energy, shift in diets and climate change are only partly dealt with while new drivers and determinants such as food waste and alternative sources of food supply are not yet addressed.

description: The proposed filter design topology is based on dual coupled resonators constructed in the form of Peano fractal geometry. A dual-band microstrip bandpass filter with a quasi-elliptic response has been designed for first time based on 1 st iteration Peano fractal geometry at resonant frequencies of 2.25 GHz and 4.825 GHz using a substrate of a relative dielectric constant of 10.8 and thickness of 1.27 mm. The performance of the bandpass filter structure has been analyzed using a method of moments (MoM) based software package, Microwave Office 2009, from Advanced Wave Research Inc. Results show that this filter possesses good frequency response characteristics in addition to dual bands gained which can be used for modern communication applications.
Are Glueballs Knotted Closed Strings?

description: Glueballs have a natural interpretation as closed strings in Yang-Mills theory. Their stability requires that the string carries a nontrivial twist, or then it is knotted. Since a twist can be either left-handed or right-handed, this implies that the glueball spectrum must be degenerate. This degeneracy becomes consistent with experimental observations, when we identify the $η_L(1410)$ component of the $η(1440)$ pseudoscalar as a $0^{-+}$ glueball, degenerate in mass with the widely accepted $0^{++}$ glueball $f_0(1500)$. In addition of qualitative similarities, we find that these two states also share quantitative similarity in terms of equal production ratios, which we view as further evidence that their structures must be very similar. We explain how our string picture of glueballs can be obtained from Yang-Mills theory, by employing a decomposed gauge field. We also consider various experimental consequences of our proposal, including the interactions between glueballs and quarks and the possibility to employ glueballs as probes for extra dimensions: The coupling of strong interactions to higher dimensions seems to imply that absolute color confinement becomes lost.

description: The NA57 experiment has collected high statistics, high purity samples of \PKzS and \PgL, $Ξ$ and $Ω$ hyperons produced in Pb-Pb collisions at 158 $A$ GeV/$c$. In this paper we present a study of the transverse mass spectra of these particles for a sample of events corresponding to the most central 53% of the inelastic Pb-Pb cross-section. We analyse the transverse mass distributions in the framework of the blast-wave model for the full sample and, for the first time at the SPS, as a function of the event centrality.

description: This article examines bank and industry concentration jointly within the static framework of Cournot competition. The general equilibrium is one in which banks form a multiplant monopoly and firm profit is zero. This is an unstable equilibrium because: (A) Firms have an incentive to (i) collude to "fight banks back" in the context of bilateral monopoly bargaining, and/or (ii) modernize their business towards financial independence; (B) Banks’ best response is (i) innovation too, combined with (ii) disciplinary credit rationing.

description: Evaluation of the incidence of deep epigastric and cardiophrenic angle lymph nodes involvement, in patients with recurrent disease after cytoreductive surgery, for colorectal cancer

Objective

The deep epigastric lymphatic basin, at the level of the inferior epigastric artery, can represent a possible dissemination pathway from the peritoneum to the extraperitoneal compartments in patients with colorectal peritoneal metastases (PM). The objective of this study was to review the computed tomography (CT) scans of patients treated by cytoreductive surgery (CRS) for PC who presented recurrence, in order to determine the role of the deep epigastric lymphatic basin in the global pattern of recurrences in these patients.

Methods

This is a retrospective study including patients treated for peritoneal metastasis from colorectal origin with curative intent, from 2012 until 2018, at our institution, and who presented with any type of disease recurrence. All CT scans were reviewed to identify the recurrent metastatic sites, and to locate the enlarged lymph nodes: at the cardio-phrenic angle level, anterior retroperitoneal compartment (deep epigastric basin), posterior retroperitoneal compartment, and distant sites.

Results

Amongst the 50 patients included, 29 patients (58%) had radiological lymph nodes involvement, versus 21 patients (42%) with no radiologically involved lymph nodes. The deep epigastric basin was involved in 8% of the patients. This group of patients had a lower median age (55) and a higher PCI median (18) than all the other groups. Furthermore, patients in this group had the highest incidence (100%) of peritoneal involvement upon recurrence, when compared to the other groups.

Conclusion

Our study confirms the potential role of the anterior abdominal lymphatic pathway, previously overlooked, in the systemic dissemination process of colorectal PM. We hereby shed into light a previously unrecognized lymphatic pathway, as an intermediate checkpoint, a relay, between the peritoneum, as an intra-abdominal organ, and the extra-abdominal compartment.
