title: Antigenic Variation in Virulence Determinants of Streptococcus zooepidemicus and Actinobacillus equuli Involved in Lower Airway Disease of the Horse and Strategies Towards Protective Immunisation
Creators: name: Ward, Chantelle Louise
Publisher: name: The Open University
Year: 1998

description: Lower airway disease (LAD) of the training Thoroughbred horse is characterised by poor performance and excess mucus and pus in the trachea. This condition, although often referred to as ‘the virus’, is significantly associated with Streptococcus zooepidemicus and Actinobacillus/Pasteurella species without evidence of viral infection.

 The degree of antigenic variability in these bacteria was assessed, to judge the number of strains that might be required in future vaccines. Particular attention was paid to the putative virulence determinants of the M-like protein and capsule of S. zooepidemicus and the iron regulated proteins (IRPs), produced only in low available iron concentrations, of Actinobacillus equuli.

 A range of Actinobacillus/Pasteurella species were isolated from the lower airway of horses, but more than half were accounted for by A.equuli. A. equuli bound and utilised equine holotransferrin for growth. The constitutive proteins of A. equuli were antigenically cross-reactive, but IRPs were more antigenically varied. Vaccines based on interference of IRPs would be likely to need more than one strain of A. equuli.

 Hot acid extracts of S. zooepidemicus were antigenically cross-reactive, but there was less opsonogenic cross-reactivity in horse blood containing natural antibodies than rabbit antisera to extracts. A vaccine based on M-like protein would be likely to need more than one type of S. zooepidemicus, but no relationship could be found between ribotype / antigenic profile and opsonogenic behaviour, suggesting that M-like protein is not necessarily the principal anti-phagocytic mechanism for these isolates, at least in vitro.

 S. zooepidemicus produces a hyaluronate capsule thought to be a virulence determinant, which is tightly bound by a protein (HAP). Immunisation with recombinant HAP significantly increased survival time and clearance of bacteria in mice challenged intraperitoneally with S. zooepidemicus. Recombinant HAP may have acted as a surrogate antigen for the capsule.

 Introduction of bacteria into ponies intratracheally produced a dose response for S. zooepidemicus and A. equuli. However, so much intercurrent infection developed (due to S. zooepidemicus and Bordetella bronchiseptica) it was concluded that conventional ponies would be unsuitable for straightforward studies of vaccine efficacy in response to experimental challenge. Alternative ways forward are discussed.

description: The “active farmer” issue has gained attention in the last CAP reforms with the increasing attention to the decoupling of the support. The 2014-2020 CAP reform has ignited the debate among stakeholders on “who” is actually entitled to receive direct payments. The analysis carried out highlights the heterogeneity in the national implementation of the rules on “active farmer” and the importance of the national legislation of some Member States in limiting the access to direct payments, regardless of EU rules. The article points out how the complexity of the rules on “active farmer” arises from the unresolved question on the nature of direct payments. The new rules do not satisfy neither who wants to grant direct payments only to “genuine” farmers nor who wants to grant support to those who, in the spirit of the new approach of direct payments, manages the agricultural land, regardless of the main activity carried out.

title: THE DESIGN, DEVELOPMENT AND EVALUATION OF THE TULKETH READING ATTITUDE INVENTORY
Creators: name: Child, Alan James
Publisher: name: The Open University
Year: 1985

description: This thesis presents an account of the design, development, application and evaluation of a reading attitude inventory. The Tulketh Reading Attitude Inventory (TRAI) was developed in response to the needs of an English Department in an 11 to 16 co-educational comprehensive school which was about to adopt the Cambridge '0’ level English Literature Syllabus (2002) Plain Texts in years 4 and 5. There was a need to identify pupils to follow this course and it seemed likely that pupils with a positive attitude to the world of books and reading would be those who would find pleasure and success in pursuing an '0’ level literature course. The TRAI was designed and developed to test this assumption and to assist in this pupil identification and selection procedure. The thesis also evaluates school examinations, teachers' subjective assessments and reading tests as methods of selecting and identifying pupils to pursue this 'O' level literature course. A group of sixty secondary school pupils was studied and their progress documented over two and a half years. The TRAI was found on test/re-test to have a product moment coefficient of reliability of +0,89 (significant at .01 level) and a predictive validity of +0.61 (significant at .01 level) when TRAI scores were correlated, using product moment, with 'O' level literature results. This suggests that the TRAI can contribute to the more accurate placement and selection of pupils on an 'O' level literature course

description: Previous attempts to bridge the gap between police and minority youths have not been successful in changing minority youths' attitudes toward officers. Two intervention programs were designed to produce positive information regarding out-group exemplars and generalization of this information to the overall out-group for police and minority youths. Evaluations of attitudes toward team members and the out-group were conducted to assess the interventions' effectiveness. In Study 1, police (n = 26) and minority youths (n = 51) competed together on heterogeneous basketball teams. Pre- and post-intervention data were compared. Police and youths reported positive ratings of out-group team members. Only the police officers demonstrated a positive shift in their attitudes toward the overall out-group. Both groups demonstrated a reduction in perceived heterogeneity of the out-group. Post hoc analyses examined the response of the youths to the intervention as well. as the decreased heterogeneity ratings. In Study 2, a similar program was evaluated to address some limitations of the first study. The police (n = 49) and minority youths (n = 40) competed together for two games on teams composed of one youth and three officers or three youths and one officer. Participants were randomly assigned to one of three conditions: pre-contact, exposure to one exemplar, and exposure to multiple exemplars. No contact versus contact and exposure to one versus multiple exemplar conditions were compared on attitudes toward the overall out-group. Both groups reported positive ratings of out-group team members. Exposure groups did not differ significantly from the control group in rating of the overall out-group on attitude and heterogeneity. Exposure to multiple exemplars was not associated with more positive ratings of the out-group as compared to exposure to a singular exemplar. Post hoc analyses explored the lack of attitude and heterogeneity change. Overall, results suggested that a short-term competitive context can result in the production of positive information regarding out-group exemplars. Results from the first study suggest that the contact may result in positive attitude change regarding the overall out-group. Further research is needed to replicate these findings.

The gross margins of the improved three-crop patterns, Aman rice (BRRIdhan3 0-Potato-Borg rice (BRRIdhan29) and Aman rice (BRRIdhan31)-Edible poded pea-Boro rice (BRRIdhan29) were 132 and 52% higher over the checked pattern of Aman rice (BRRIdhan31):-Fallow-Boro rice (BRRIdhan29), respectively. The gross margin of the earlier pattern was also 51% higher than Aman rice (BRRIdhan31)-Pea (Edible poded)-Boro rice (BRRIdhan29) three-crop. systerris. These two cropping patterns have been found agro-economically profitable which might be validated in farmers' fields for large scale adoption.

description: 22 GHz water vapor emission was observed toward the central region of the spiral starburst galaxy NGC 253. Monitoring observations with the 100-m telescope at Effelsberg and measurements with the BnC array of the VLA reveal three distinct velocity components, all of them blueshifted with respect to the systemic velocity. The main component arises from a region close to the dynamical center and is displaced by <1 arcsec from the putative nuclear continuum source. The bulk of this maser component is spread over an area not larger than 70 x 50 mas. Its radial velocity may be explained by masing gas that is part of a nuclear accretion disk or of a counterrotating kinematical subsystem or by gas that is entrained by the nuclear superwind or by an expanding supernova shell. A weaker feature, located 5 arcsec to the northeast, is likely related to an optically obscured site of massive star formation.

description: We investigate the viability of highly efficient organic solar cells (OSCs) based on non-fullerene acceptors (NFA) by taking into consideration efficiency loss channels and stability issues caused by triplet excitons (TE) formation. OSCs based on a blend of the conjugated donor polymer PBDB-T and ITIC as acceptor were fabricated and investigated with electrical, optical and spin-sensitive methods. The spin-Hamiltonian parameters of molecular TEs and charge transfer TEs in ITIC e.g., zero-field splitting and charge distribution, were calculated by Density Functional Theory (DFT) modelling. In addition, the energetic model describing the photophysical processes in the donor-acceptor blend was derived. Spin-sensitive photoluminescence measurements prove the formation of charge transfer (CT) states in the blend and the formation of TEs in the pure materials and the blend. However, no molecular TE signal is observed in the completed devices under working conditions by spin-sensitive electrical measurements. The absence of a molecular triplet state population allows to eliminate a charge carrier loss channel and irreversible photooxidation facilitated by long-lived triplet states. These results correlate well with the high power conversion efficiency of the PBDB-T:ITIC-based OSCs and their high stability.
title: The decomposition and upgrading of agricultural wastes by the earthworm Eisenia fetida (Savigny 1826)
Creators: name: Knight, David
Publisher: name: The Open University
Year: 1988

description: Cattle slurry from various sources, both digested and undigested, was tested as a culture medium for growing the earthworm Eisenia fetida. Earthworm growth was related to the physical-chemical characteristics of the slurry and the presence of bulk organic material. Cattle slurry from several sites which had been mechanically separated to produce a stackable solid had different physico-chemical characteristics and produced varying earthworm growth responses. In particular, solids from Bore Place farm had a high ionic conductivity and ammonium ion concentration which reduced growth. The woodchip bedding used was found to be inhibitive to E.fetida. Solids that were pretreated by high temperature composting as opposed to room-temperature aging before earthworm inoculation generally produced a higher earthworm biomass, but only after an initial inhibitory effect was overcome. The residue of anaerobically digested cattle slurry can also be used to support E.fetida, although in some cases the digestion process can inhibit subsequent earthworm growth. The addition of cellulose to cattle waste, using different cellulosic bulking agents, showed the importance of both the form of carbon present and the C/N ratio on earthworm growth, effecting both nutritional and environmental qualities of a waste. Results using an artificial cellulose based medium showed how earthworms require a complex waste ecosystem in equilibrium to survive. Under laboratory conditions E.fetida does not provide a major contribution to the changes in physico-chemical characteristics during decomposition of cattle solids compared to the action of micro-organisms. The main effect of earthworms may therefore be purely physical in nature, macerating the solids and reducing particle size. Undigested and digested worm worked material can support plant growth but requires further pre-treatment such as bulking with peat to allow plant growth equivalent to a commercial compost.

description: The objective of this study is to determine if there are important size and industry effects on financial pertormance of agricultural cooperatives. The performance of 43 dairy, food, grain, and farm supply cooperatives in the US was analyzed over the period 1970-1987 using financial ratios derived from accounting data. The analysis revealed significant size and industry effects. Large regional cooperatives are more efficient in utilizing their assets to generate sales, while small regional cooperatives have higher profitability. The findings suggest that the emphasis on growth may not always produce· beneficial results among agricultural cooperatives. Among the four industries studies, the dairy regional cooperatives appear to be the strongest performers, while the food marketing cooperatives are characterized by the lowest performance measures. Since both dairy and food cooperatives engage in value-added processing, this difference in performance makes it difficult to reach clear conclusions about possible advantages or disadvantages of. vertical integration relative to traditional cooperative activities. Trend analysis indicates that the profitability of the agricultural cooperatives in all industry and size categories declined in response to the downturn in US agriculture after 1980. While the decline in profitability was at similar rates for both large and small cooperatives, the variation of efficiency and leverage was in opposite directions. Large cooperatives may be expected to continue improving their asset utilization without relative improvement in profitability, and increasing the level of their debt in relation to equity.

description: We study how the evaporation rate of spherically symmetric black holes is affected through the extraction of radiation close to the horizon. We adopt a model of extraction that involves a perfectly absorptive screen placed close to the horizon and show that the evaporation rate can be changed depending on how close to the horizon the screen is placed. We apply our results to show that the scrambling time defined by the Hayden-Preskill decoding criterion, which is derived in Pennington's work (arXiv:1905.08255) through entanglement wedge reconstruction is modified. The modifications appear as logarithmic corrections to Pennington's time scale which depend on where the absorptive screen is placed. By fixing the proper distance between the horizon and screen we show that for small AdS black holes the leading order term in the scrambling time is consistent with Pennington's scrambling time. However, for large AdS black holes the leading order Log contains the Bekenstein-Hawking entropy of a cell of characteristic length equal to the AdS radius rather than the entropy of the full horizon. Furthermore, using the correspondence between the radial null energy condition (NEC) and the holographic c-theorem, we argue that the screen cannot be arbitrarily close to the horizon. This leads to a holographic argument that black hole mining using a screen cannot significantly alter the lifetime of a black hole.

description: The theory of quantum information provides a common language which links disciplines ranging from cosmology to condensed-matter physics. For example, the delocalization of quantum information in strongly-interacting many-body systems, known as quantum information scrambling, has recently begun to unite our understanding of black hole dynamics, transport in exotic non-Fermi liquids, and many-body analogs of quantum chaos. To date, verified experimental implementations of scrambling have dealt only with systems comprised of two-level qubits. Higher-dimensional quantum systems, however, may exhibit different scrambling modalities and are predicted to saturate conjectured speed limits on the rate of quantum information scrambling. We take the first steps toward accessing such phenomena, by realizing a quantum processor based on superconducting qutrits (three-level quantum systems). We implement two-qutrit scrambling operations and embed them in a five-qutrit teleportation algorithm to directly measure the associated out of-time-ordered correlation functions. Measured teleportation fidelities, Favg = 0.568 +- 0001, confirm the occurrence of scrambling even in the presence of experimental imperfections. Our teleportation algorithm, which connects to recent proposals for studying traversable wormholes in the laboratory, demonstrates how quantum information processing technology based on higher dimensional systems can exploit a larger and more connected state space to achieve the resource efficient encoding of complex quantum circuits.

Hypermedia, students with learning disabilities and study skills
Creators: name: Shaheen, Nanda
Publisher: name: American University
Year: 2023

description: The purpose of this study was to examine the effects of computer-based instruction in the development of study skills on junior high students with learning disabilities. Research in the deficiency of study skills in students with learning disabilities has been documented and has given educators indicators that this is an area where much work is needed. Results from studies conducted on the strategies of overcoming these problems indicate that study guides, whether teacher directed or student directed, produce significantly higher performance then self-study with students with learning disabilities (Horton & Lovitt, 1989). The study used a quasi-experimental design to investigate the enhancement of study skills after the introduction of a hypermedia authoring system used to develop study guides. It was hypothesized that there would be a significant positive impact in the acquisition of study skills, as assessed by the Learning and Study Strategies Inventory-HS, between a control group and an experimental group of junior high students with learning disabilities. The two groups consisted of thirty-two students from a private D.C. school exclusively for children with learning disabilities. Both groups were pretested and posttested using the inventory as well as a curriculum based content area test. In addition, both groups attended classes which were held for forty-five minutes a day, five days a week, over the course of a seven-week period. Statistical methods used to evaluate the effectiveness of an intervention included ANOVA, t tests, correlations (using Pearson's R), and other inferential statistical methods. The dependent variables measured were the students' mastery of study strategies as measured by gain scores pre and post tests of the ten subtests of the LASSI-HS, as well as, students' mastery of content area in Humanities as measured by gain scores on pre and post tests designed by the classroom teacher. Statistical analysis proved that statistical significance was only found on the subtest measuring student's attitude and motivation towards school in general. Practical significance found that hypermedia, increased student motivation towards the study guide creation and retention of content information.

description: The Box-Cox methodology has been extensively applied since it·was first introduced in 1964. This study establishes that the function currently used as a basis for implementing the Box-Cpx methodology is not a valid probability qensity function. The proper density function associated with the random variable underlying the Box-Cox methodology is derived.· Simulation evidence documents that the original Box-cox approach can result in considerable bias.

description: The purpose of this study was to examine the effects of computer-based instruction in the development of study skills on junior high students with learning disabilities. Research in the deficiency of study skills in students with learning disabilities has been documented and has given educators indicators that this is an area where much work is needed. Results from studies conducted on the strategies of overcoming these problems indicate that study guides, whether teacher directed or student directed, produce significantly higher performance then self-study with students with learning disabilities (Horton & Lovitt, 1989). The study used a quasi-experimental design to investigate the enhancement of study skills after the introduction of a hypermedia authoring system used to develop study guides. It was hypothesized that there would be a significant positive impact in the acquisition of study skills, as assessed by the Learning and Study Strategies Inventory-HS, between a control group and an experimental group of junior high students with learning disabilities. The two groups consisted of thirty-two students from a private D.C. school exclusively for children with learning disabilities. Both groups were pretested and posttested using the inventory as well as a curriculum based content area test. In addition, both groups attended classes which were held for forty-five minutes a day, five days a week, over the course of a seven-week period. Statistical methods used to evaluate the effectiveness of an intervention included ANOVA, t tests, correlations (using Pearson's R), and other inferential statistical methods. The dependent variables measured were the students' mastery of study strategies as measured by gain scores pre and post tests of the ten subtests of the LASSI-HS, as well as, students' mastery of content area in Humanities as measured by gain scores on pre and post tests designed by the classroom teacher.

description: Ultra-cool white dwarfs are among the oldest stellar remnants in the Universe. Their efficient gravitational settling and low effective temperatures are responsible for the smooth spectra they exhibit. For that reason, it is not possible to derive their radial velocities or to find the chemistry of the progenitors. The best that can be done is to infer such properties from associated sources, which are coeval. The simplest form of such a system is a common proper motion pair where one star is an evolved degenerate and the other a main-sequence star. In this work, we present the discovery of the first of such a system, the M dwarf LHS 6328 and the ultra-cool white dwarf PSO J1801+625, from the Pan-STARRS 1 3$π$ survey and the $Gaia$ Data Release 2. Follow-up spectra were collected covering a usable wavelength range of 3750-24500 Å. Their spectra show that the white dwarf has an effective temperature of 3550K and surface gravity of $\log g = 7.45 \pm 0.13$ or $\log g = 7.49 \pm 0.13$ for a CO or He core, respectively, when compared against synthetic spectra of ultra-cool white dwarf atmosphere models. The system has slightly subsolar metallicity with -0.25 < [Fe/H] < 0.0, and a spatial velocity of (U, V, W) = ($-114.26 \pm 0.24$, $222.94 \pm 0.60$, $10.25 \pm 0.34$) km s $^{-1}$ the first radial velocity and metallicity measurements of an ultra-cool white dwarf. This makes it the first and only benchmark of its kind to date.

classificationCode: 3904
subject: Specialist studies in education

description: This research identified teaching situations classified as critical incidents in the online classroom. These teaching events were categorized to help faculty members recognize potential critical events before they start, and to use the incidents to enhance online learning opportunities. Online faculty and students were surveyed and interviewed; data was returned to the respondents for corroboration. Results showed that the majority of critical incidents occurred due to lack of prior training and understanding of the online classroom as a learning environment. Recommendations are for institutions to require and provide more in-depth faculty training to teach in the online environment.

description: We reanalyze the results of our extensive Hartree-Fock + BCS calculation from new points of view paying attention to the properties of unstable nuclei. The calculation has been done with the Skyrme SIII force for the ground and shape isomeric states of 1029 even-even nuclei ranging 2 <= Z <= 114. We also discuss the advantages of the employed three-dimensional Cartesian-mesh representation, especially on its remarkably high precision with apparently coarse meshes when applied to atomic nuclei. In Appendices we give the coefficients of finite-point numerical differentiation and integration formulae suitable for Cartesian mesh representation and elucidate the features of each formula and the differences from a method based on the Fourier transformation.

description: Total demand for beef has declined during the 1980's, but demand for the higher valued cuts has increased relative to the average. Price ratios of retail and wholesale cuts to the carcass composite price were used to develop trends in demand for individual cuts. Increased demand for higher quality is clear; demand for convenience (steak or ground beef versus roasts) was indicated. Demand for some cuts vary among seasons.
