title: The effectiveness of foot orthoses as a treatment for plantar ulceration in leprosy : a study of the efficacy, acceptability, appropriateness and implantation of a podiatric regimen
Creators: name: Cross, Hugh
Publisher: name: The Open University
Year: 1996

description: This was a holistic study. Four themes were investigated to demonstrate the effectiveness of orthotic intervention for plantar ulceration affecting leprosy impaired subjects in India. 1. Efficacy Efficacy was demonstrated, primarily, through analysis of data pertaining to a controlled trial. Thirty-seven subjects, presenting with leprosy impairments including anaesthesia and plantar ulceration, were fitted with orthoses and allocated to an experimental group. Thirty-four similar subjects, were not offered orthoses and were allocated to a control group. After 8 months 52% of the ulcers presented by Experimental group and 12% of the ulcers presented by the Control group had healed. The rationale supporting the prescription of orthoses was investigated using the EMED system. It was demonstrated that intervention with orthoses resulted in significantly lower sub pedal peak pressures than intervention with leprosy sandals. 2. Implementation and Sustain ability Ulcer assessment data from March 1994 to January 1995 were used to compare the effects of orthoses supplied by the investigator with orthoses supplied by an Indian technician. The service, evaluated on the strength of these findings, was considered to have been successfully implemented. The analysis of data, collected from January 1995 to December 1995, was used to explain why the service was not sustained at an acceptable level. 3. Acceptability Interview data were analysed to describe the attitudes of the subjects to the intervention (n = 46). Indications from the analysis were that neither ulcer status (healed or unresolved) nor group allocation (Experimental or Control) affected attitudes towards the intervention. A general indication was that the intervention was favourably endorsed. 4. Appropriateness Using the Delphi technique (n = 10), a consensus on indicators of "appropriate" impairment control measures was sought. Differences of opinion were not resolved, but group priorities were ranked and a polled response was recorded. The results of the study were similar to the criteria suggested by the Delphi contributors.

description: Corynactis sp.
(Fig. 8)
 Material examined. 11 specimens, ZRC.CNI.1357 (REL331–337, REL339), Pulau Ubin Jetty, Singapore, coll. R. M. Oh, January 2018.
 Description. Body smooth, with visible longitudinal white lines spanning the entire column. Body column uniform in colour: purple, rust red, yellow, orange or blue. Body column short. Mouth outline round, elevated at the disc centre. Tentacles arranged in three or more circles of increasing radius around mouth (den Hartog et al., 1993). All tentacles translucent, ending in rounded, beige-coloured acrospheres (Acuña & Garese, 2009). Diameter of tips ranges from 15 to 20 mm. Mesenteries can be complete or incomplete. Often found in groups of three or more individuals.
 Remarks. These animals may represent an undescribed species, but more extensive collections in the region will help ascertain its status in relation to other nominal species. Corynactis sp. most closely resembles Corynactis caribbeorum but is differentiated by a uniformly coloured, highly mutable body column lacking a distinct scapulus. Furthermore, Corynactis caribbeorum is found in the Caribbean and Atlantic Ocean near north Africa (Fautin, 2016).
 Locally, Corynactis sp. is commonly known as the ‘balltip’ corallimorpharian from its distinct acrosphere shape, and is widespread in the intertidal habitats of both northern and southern shores in Singapore (Table 2). During low tide, its body column envelops the tentacles and oral disc. Once submerged the body column retracts and tentacles are fully extended. Individuals are identified in the field by its uniformly coloured, mutable body form adhering to common substrata including coral rock and granite pillars, and could be easily removed from the substrata.

description: Moorflächen sind auf den Kontinenten überall vorhanden. Aus Mooren lässt sich durch Entwässerung und Trocknung leicht der hochporöse Torfgewinnen. Torf ist ein natürliches und ungiftiges Rohmaterial, das wegen seiner variablen Struktur gegenüber Wasser außergewöhnliches adsorptives Verhalten zeigt. Dennoch wird Torf industriell nur bescheiden genutzt. Allerdings hinterlässt der Tagebau ausgetorfte Landschaften, die renaturiert werden müssen, weil Torf nur sehr langsam nachwächst. In dem vorliegenden Artikel wird über mikroskopische und gravimetrische Untersuchungen der Torfoberfläche berichtet. Sie hatten das Ziel, Benetzungsvorgänge zu optimieren, neue Anwendungen zu finden und bestehende zu verbessern. Es wurden ausgedehnte fraktale Bereiche gefunden. Die Benetzung ließ sich durch Zugabe von Tensiden beschleunigen.
description: Moor is distributed everywhere at the continents. By drying of moor highly porous peat may be developed. Peat is a natural innocuous raw material which can be easily quarried. However, overcast mining leaves behind emptied out ground. This should be renaturised, because moor grows very slowly. Nevertheless peat is used seldom in industry. Water exhibits unusual adsorptive behaviour in contact with the peat surface. The microstructure of peat was investigated by means of microscopy and gravimetry with the aim to find new applications und to improve wetting. The surface exhibits large fractal regions. Using tensides water wetting may be speeded up.

description: We examine the spatial integration of wheat, rice and pearl millet in the Indian states of Bihar, Haryana, and Uttar Pradesh after the reforms of 2002 which liberalized inter-state trade. Our data represent a large share oflndia's cereal grains. The government regulates markets for staple foods heavily; almost all grain is marketed through government licensed markets that impose a price floor. This could discourage private investment in storage capacity among farmers and traders, impacting market integration. We find little evidence of market integration despite the 2002-03 reforms, and this fragmentation is particularly notable for smaller, and less regulated crops.

Die daraus gewonnen Erkenntnisse ermöglichen, das Verhalten von Kindern besser zu verstehen und heilpädagogische Prinzipien abzuleiten. Mittels einer qualitativen Inhaltsanalyse werden neurowissenschaftliche Texte hinsichtlich der Kategorien Bedeutung, Entwicklung, Auswirkungen und Einflussfaktoren des exekutiven Systems untersucht. Aus der Analyse geht hervor, wie das exekutive System mit dem limbischen System im Gehirn zusammenhängt. Aufgrund der Funktionsweise und der Kommunikation beider Systeme lassen sich
 Konsequenzen für das Verhalten formulieren. Die Ergebnisse der vorliegenden Arbeit legen dar, dass das exekutive System das Verhalten durch Kontroll- und Regulationsprozesse beeinflussen kann, letztlich aber die Gefühle aus dem limbischen System das Verhalten weitgehend bestimmen.
title: Children's representations of asthma : developmental changes and influences on knowledge, asthma control, management and perceptions of quality of life
Creators: name: Croft, Elizabeth
Publisher: name: The Open University
Year: 1996

description: A between and within group design using a semi-structured interview was used to explore the content of children's illness representations of their asthma and the influence of these representations on knowledge, asthma management , asthma control and perceived quality of life. A sample of 41 asthmatic children and their parents were recruited from GP practices. Children were divided into two age groups 8-11 years and 12-16 years. Test-retest reliability was performed on a sample from each age group. Children were found to have similar illness representations across the age groups although developmental patterns were found in the beliefs children offered about the cause of their asthma, and in the way in which illness representations influenced outcome. For the younger children, causal attributions appear to be more influential in outcome than the constellation of illness representations that were tested Older children appeared to be beginning to approximate more adult patterns of holding a set of beliefs that influenced outcome. A major issue in the study was the variable reliability of the measures used Stability over time for the younger children was attributed to greater parental influence. The instability of measures over time for older children was considered to reflect developmental influences. Some support was found for the proposed self-regulatory function of illness representations although the complexity of findings highlights the need for longitudinal research to track developmental changes in children's illness representations. The implications for future research and clinical practice are discussed.

description: We study the generalized sum rules and polarizabilities of the nucleon in the framework of the hypercentral constituent quark model. We include in the calculation all the well known $3^*$ and $4^*$ resonances and consider all the generalized sum rules for which there are data available. To test the model dependence of the calculation, we compare our results to the results obtained in the harmonic oscillator CQM. We furthermore confront our results to the model-independent sum rules values and to the predictions of the phenomenological MAID model. The CQM calculations provide a good description of most of the presented generalized sum rules in the intermediate $Q^2$ region (above $\sim0.2$ GeV$^2$) while they encounter difficulties in describing these observables at low $Q^2$, where the effects of the pion cloud, not included in the present calculation, are expected to be important.

description: Abstract: Flora, mire vegetation, actual and fossil pollen precipitation of medieval fish ponds are investigated. At present days each pond shows different stages of mire development. Small sedge communities of Caricetum fuscae and Caricetum rostratae prevail, in open waters Potamogeton natans, Juncus bulbosus and at the pond margins Carex rostrata grow. The pollen precipitation is compared with the actual vegetation cover of the mire and its 500 m radius. Soil dependent mire formation in the brook valley starts in post-Roman times. After construction of the fish ponds and increasing forest clearance the mire development continues by increasing peat formation, and in the ponds limno-minerogenic sediments accumulate fastly. Mire desiccation at the valley margins and mesotrophic fen peat formation in the remnant ponds during the last 250 years by surrounding afforestation lead to the present day status of a protected area within the Nature 2000 fauna-flora-habitat system. Proposals for nature reserve management are applied to the lake and mire biotops as well as the surrounding forests.
description: Zusammenfassung: Flora, Moorvegetation, rezente und fossile Pollenführung der im Mittelalter angelegten Fischteiche Drei Seen wurden untersucht. Jeder der Seen weist aktuell unterschiedliche Stadien der Moorentwicklung auf. Kleinseggengesellschaften des Caricetum fuscae und Caricetum rostratae herrschen vor, im freien Wasser Potamogeton natans, Juncus bulbosus und ufernah Carex rostrata. Der Pollenniederschlag wird mit der aktuellen Vegetation im Moor und dem 500 m-Umkreis verglichen. Die soligene Moorentwicklung im Bachtal beginnt in der Nachrömerzeit. Mit Anlage der Fischteiche und den zunehmenden spätmittelalterlichen Waldrodungen geht die Moorentwicklung am Talrand in verstärkte Torfbildung über, während die limno-minerogenen Teichsedimente rasch akkumulieren. Randliche Mooraustrocknung und mesotrophe Riedtorfbildung in den Teichen führen seit den Aufforstungen der letzten 250 Jahre zum heutigen Zustand des FFH-Schutzgebietes. Vorschläge zum Biotop-Management erstrecken sich auf Gewässer, Moor und umgebende Forsten.

description: Abstract: The purpose of adding clay to horticultural growing media is to achieve objectives such as a well-balanced nutrient supply, buffering of the pH-value, improvement of the rewettability, cohesion of the growing medium and supply of trace elements. Criteria for choosing clay types for specific applications are necessary to assess the suitability of original materials as well as processed clays in a reliable way. A wide range of clays for different applications was chosen for this study. Differences in the mineralogical composition and in pretreatment of the selected clays resulted in specific physical and chemical characteristics of the different growing media mixes. The influence of different clays on the rewettability and cohesion of growing media was analyzed in laboratory experiments which resulted in the definition of important parameters for selection of clays and suitable methods for processing. Clays with strong K and P fixation as well as clays with spontaneous release of these macronutrients were identified. The effects of clays on the flow of nutrients were documented in crop tests. growth-trials regarding Mn toxicity, carried out with clays with different contents of active Mn, proved that an existing RHP-threshold value for Mn in clays for growing media is not justified.
description: Zusammenfassung: Der Zusatz von Ton zu gärtnerischen Kultursubstraten ist mit vielen unterschiedlichen Zielen, wie ausgeglichener Nährstoffversorgung, Pufferung des pH-Wertes, Verbesserung der Benetzbarkeit, Bindigkeit des Substrates und Spurenelementversorgung, verknüpft. Geeignete Kriterien für die Auswahl von Tonen für spezifische Anwendungen sind nötig, um eine verlässliche Bewertung sowohl der Substratausgangsstoffe als auch von aufbereiteten Tonen zu ermöglichen. In dieser Studie wurde eine große Bandbreite von Tonen für verschiedene Anwendungen ausgewählt. Unterschiede in der mineralogischen Zusammensetzung und Aufbereitung der ausgewählten Tone spiegeln sich bei den entsprechenden physikalischen und chemischen Eigenschaften des Substrates wieder. Der Einfluss verschiedener Tone auf die Wiederbenetzbarkeit und Bindigkeit von Substraten wurde in Laborexperimenten untersucht und wichtige Parameter für die Auswahl bestimmter Tonspezies und deren Aufbereitung abgeleitet. Tone mit starker K- und P-Fixierung als auch solche mit spontaner Freisetzung dieser Makronährstoffe wurden identifiziert und in Kulturversuchen Toneffekte auf Nährstoffflüsse dokumentiert. Untersuchungen zur Mangantoxizität an Tonen mit unterschiedlichen Anteilen an aktivem Mangan ergaben, dass der bestehende RHP-Grenzwert für Mn in Substrattonen nicht gerechtfertigt ist.

description: Abstract: In the last two decades, the concentration of dissolved organic carbon (DOC) has increased in some of the dams of the Ore Mountains, as well as in many regions in the northern hemisphere. It is feared by the State Dam Authority of Saxony and by local drinking water suppliers, that through the revitalisation of bogs, the DOC-concentration in rivers and dams will increase further. According to monitoring data for the time period of 2006 to 2011, it is evident that the blocking of ditches in a small bog revitalisation area (4.2 ha or max. 4 % of the Carlsfeld dam catchment area) did not lead to an increased DOC concentration in the adjoining rivers. The results are compared with current international literature.
description: Zusammenfassung: In den letzten zwei Jahrzehnten ist die Konzentration an gelöstem organischem Kohlenstoff (DOC) in einigen Talsperren des Erzgebirges wie auch in vielen Regionen der nördlichen Hemisphäre gestiegen. Seitens der Landestalsperrenverwaltung des Freistaates Sachsen als Rohwasserlieferant und der örtlichen Trinkwasserversorger wird befürchtet, dass sich die DOC-Konzentration in den Fließgewässern und Talsperren durch Moorrevitalisierung zusätzlich erhöht. Anhand von Monitoringdaten für den Zeitraum 2006 bis 2011 wird gezeigt, dass der Grabenanstau auf einer kleinen Regenerationsfläche (4,2 ha bzw. max. 4 % des Einzugsgebietes der Talsperre Carlsfeld) nicht zu erhöhten DOC-Konzentrationen in den anliegenden Fließgewässern geführt hat.

description: In this work we study and compare the features of gravitational entropy near the throat of transversable wormholes formed by exotic matter and wormholes in galactic halos. We have verified that gravitational entropy and entropy density of these wormholes in regions near their throats are indistinguishable for objects of same throat, despite the fact they are described by different metrics and by distinct energy-momentum tensors. We have found that the gravitational entropy density diverges near the throat for both cases, probably due to a non-trivial topology at this point, however allowing the interesting interpretation that a maximum flux of information can be carried through the throat of these wormholes. In addition, we have found that both are endowed with an entropic behaviour similar to Hawking-Bekenstein's entropy of non-rotating and null charge black holes.

title: Affordances of Learning Analytics for Mediating Learning
Creators: name: Farrell, Tracie
Publisher: name: The Open University
Year: 2018

description: Learning analytics acceptance and adoption is a socio-technological endeavour. Understanding how learning analytics impact practice is an important part of demonstrating their value. In the study presented in this thesis, "Mediated Learning" provides a framework through which to describe how learning analytics can impact psychological, social and material aspects of learning, from the perspective of educators and learners. It also offers a structure through which to make recommendations for improving the mediatory effects of learning analytics. A qualitative research design, based on "Grounded Theory" was implemented and 10 educators from 3 European universities were recruited through convenience and purposive sampling for exploratory interviews. A subsequent case study of the Open University provided critical perspectives from both educators (n=18) and learners (n=22) about the institutional, departmental, domain-related and epistemological factors that broadly influence perceptions of learning analytics. The study applied "Affordance Theory" to identify what participants were most easily able to recognise as beneficial to their own practice. Participant contributions were open-coded to uncover emerging themes and then organised into thematic categories and subcategories. Respondent validation, as well as triangulation of data between the exploratory interviews and focus groups support the validity of the study. Findings suggested that domain-related epistemological assumptions and previous experience influence how and why an individual could make use of learning analytics insights. Gaining stakeholder acceptance involves targeting the right training and opportunities at the appropriate disciplines. Findings also indicate that learning analytics has the strongest mediatory effect for learners when the technology is capable of exposing them to other learners' strategies, or when it assists them personally, and continually in goal orientation adoption. The implications of the study are important for higher education institutions looking to implement large-scale learning analytics initiatives, in particular, those with a diverse student body.

description: Five tomato cultivars (Calypso, Walter, Indian River, Floradade and Caraibe) were evaluated for yield and tolerance to fusarium wilt in two agro-eoclogical zones in St. Lucia. The trials were conducted on farmers' holdings in 1984 during the dry (January-May) and wet (July-December) cropping seasons. Cultivars with 0.9 per cent of total plant population affected by the disease were designated as tolerant; those with 10-20 per cent, moderately tolerant; those with 21-49 per cent, susceptible; and those with more than 507., highly susceptible. In the dry cropping season, Caraibe and Calypso were both moderately tolerant to the disease; Walter, susceptible and Indian River and Floradade, highly susceptible. In the wet cropping season Caraibe was moderately tolerant while Calypso, Walter, Floradade and Indian River were all highly susceptible. Caraibe produced an average yield of 31 tonnes ha-l in the dry cropping season and 10 tonnes ha- l in the wet season.
Assessing the impact of U.S. public opinion : congressional roll call votes on seven free trade agreements
Creators: name: MacIsaac, Roderick
Publisher: name: University of British Columbia
Year: 2011

description: Even with the heterogeneous nature of public attitudes on trade liberalization, public opinion still matters in the voting behavior of Congress. This paper examines the impact of public opinion on seven free trade agreements. The conclusion is that public attitudes play a significant role in the outcome of roll call voting in the House of Representatives. In accordance with Interest Group Theory, Democrats are highly sensitive to interests as expressed as public opinion and as campaign contributions. In accordance with Delegation Theory, on the other hand, House Republicans are consistently more supportive of the President on trade policy, even when their constituents' views on free trade agreements tend towards popular opposition. Applying the same variables to the Senate, however, did not lead to the same conclusion. This suggests some fundamental representational differences in Congress. The most obvious structural difference as it applies to public opinion is the distinctive election cycles for each chamber.

Characterization of velocity-gradient dynamics in incompressible turbulence using local streamline geometry

Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: This study develops a comprehensive description of local streamline geometry and uses the resulting shape features to characterize velocity gradient ($A_{ij}$) dynamics. The local streamline geometric shape parameters and scale-factor (size) are extracted from $A_{ij}$ by extending the linearized critical point analysis. In the present analysis, $A_{ij}$ is factorized into its magnitude ($A \equiv \sqrt{A_{ij}A_{ij}}$) and normalized tensor $b_{ij} \equiv A_{ij}/A$. The geometric shape is shown to be determined exclusively by four $b_{ij}$ parameters -- second invariant, $q$; third invariant, $r$; intermediate strain-rate eigenvalue, $a_2$; and, angle between vorticity and intermediate strain-rate eigenvector, $ω_2$. Velocity gradient magnitude $A$ plays a role only in determining the scale of the local streamline structure. Direct numerical simulation data of forced isotropic turbulence ($Re_λ\sim 200 - 600$) is used to establish streamline shape and scale distribution and, then to characterize velocity-gradient dynamics. Conditional mean trajectories (CMTs) in $q$-$r$ space reveal important non-local features of pressure and viscous dynamics which are not evident from the $A_{ij}$-invariants. Two distinct types of $q$-$r$ CMTs demarcated by a separatrix are identified. The inner trajectories are dominated by inertia-pressure interactions and the viscous effects play a significant role only in the outer trajectories. Dynamical system characterization of inertial, pressure and viscous effects in the $q$-$r$ phase space is developed. Additionally, it is shown that the residence time of $q$-$r$ CMTs through different topologies correlate well with the corresponding population fractions. These findings not only lead to improved understanding of non-local dynamics, but also provide an important foundation for developing Lagrangian velocity-gradient models.
Investigating longitudinal changes in real-ear to coupler difference measurements in infants
Creators: name: Bingham, Kristina
Publisher: name: University of British Columbia
Year: 2011

description: The real-ear-to-coupler difference (RECD) measurement is a commonly-used clinical procedure that quantifies the difference in sound-pressure level between a 2-cc coupler and an individual's ear canal. The SPL levels in infant ears are highly variable and significantly higher than the SPL levels present in average adult ears, which makes the quantification of SPL levels in infant ears extremely important for threshold determination and the fitting of amplification. The purpose of this study was to examine longitudinal changes in RECD values in newborn infants, over a 1 -month interval, to determine whether a significant decrease in RECD values takes place, and whether that decrease is predictable from either the infant's corrected age or their initial RECD values. Using standard (226Hz) and high frequency (1000 Hz) tympanometry, measures of static admittance and ear canal volume were also evaluated to determine their predictive ability regarding frequency specific RECD values. Measurement error associated with the RECD was quantified and then compared to the magnitude of RECD changes over a 1 - month interval. A multi-variate analysis of variance (MANOVA) was performed and revealed an overall significant change in RECD values over a 1 month interval. Forward regression analysis further revealed corrected age as a predictor of RECD values at 3 frequencies and initial RECD values as a predictor at 1 frequency. Static admittance was a larger predictor of RECD values when compared to ECV, with the exception of the lowest and highest frequencies (0.25 and 6 kHz). Magnitude of the test-retest variability associated with the RECD measurement was not large but variability was large enough to obscure longitudinal RECD changes over a 1-month period. Consequently, it may be clinically unnecessary to re-measure an RECD within an infant's first month of life, to account for changes in ear canal acoustics between initial screening tests and follow-up assessments. The best measures of static admittance and ear canal volume in infants remains undetermined and a strong need exists for further longitudinal data in infant populations.

Take it Easy on Yourself: The Role of Self-Compassion in Response to Social Ostracism
Creators: name: Clark, Joshua L.
Publisher: name: American University
Year: 2023

description: Self-compassion involves forgiving oneself following failure, viewing negative emotions from a mindful perspective, and understanding that all human beings are imperfect (Neff, 2003). Self-compassion is associated with a host of positive psychological and physical variables, and it can even be induced to help individuals deal with stress. The present study examines whether self-compassion can be induced in a student sample and whether this inducement can help participants cope with social ostracism. Results indicate that the inducement was not effective in helping individuals respond adaptively to the ostracism manipulation. Discussion focuses on potential problems with the methodology and future directions for research on self-compassion.

description: Numerical studies of gas accretion onto supermassive black hole binaries (SMBHBs) have generally been limited to conditions where the circumbinary disk (CBD) is 10-100 times thicker than expected for disks in active galactic nuclei (AGN). This discrepancy arises from technical limitations, and also from publication bias toward replicating fiducial numerical models. Here we present the first systematic study of how the binary's orbital evolution varies with disk scale height. We report three key results: (1) Binary orbital evolution switches from outspiralling for warm disks (aspect ratio ~0.1), to inspiralling for more realistic cooler, thinner disks at a critical aspect ratio ~0.04, corresponding to orbital Mach number ~25. (2) The net torque on the binary arises from a competition between positive torque from gas orbiting close to the black holes, and negative torque from the inner edge of the CBD, which is denser for thinner disks. This leads to increasingly negative net torques on the binary for increasingly thin disks. (3) The accretion rate is modestly suppressed with increasing Mach number. We discuss how our results may influence modeling of the nano-Hz gravitational wave background, as well as estimates of the LISA merger event rate.

The Quantum Superstring as a WZNW Model with N=2 Superconformal Symmetry

description: We present a new development in our approach to the covariant quantization of superstrings in 10 dimensions which is based on a gauged WZNW model. To incorporate worldsheet diffeomorphisms we need the quartet of ghosts $(b_{zz},c^{z}, \b_{zz}, \g^{z})$ for topological gravity. The currents of this combined system form an N=2 superconformal algebra. The model has vanishing central charge and contains two anticommuting BRST charges, $Q_{S}=Q_{W} + \oint \g^{z} b_{zz} + \oint η_{z}$ and $Q_{V} = \oint c^{z} \Big(T^{W}_{zz} + {1\over 2} T^{top}_{zz}\Big) + \g^{z} (B^{W}_{zz} + {1\over 2} B^{top}_{zz} \Big)$, where $η_{z}$ is obtained by the usual fermionization of $\b_{zz}, \g^{z}$. Physical states form the cohomology of $Q_{S}+Q_{V}$, have nonnegative grading, and are annihilated by $b_{0}$ and $β_{0}$. We no longer introduce any ghosts by hand, and the formalism is completely Lorentz covariant.

title: Affordances of Learning Analytics for Mediating Learning
Creators: name: Farrell, Tracie
Publisher: name: The Open University

description: Learning analytics acceptance and adoption is a socio-technological endeavour. Understanding how learning analytics impact practice is an important part of demonstrating their value. In the study presented in this thesis, ''Mediated Learning" provides a framework through which to describe how learning analytics can impact psychological, social and material aspects of learning, from the perspective of educators and learners. It also offers a structure through which to make recommendations for improving the mediatory effects of learning analytics. A qualitative research design, based on "Grounded Theory" was implemented and 10 educators from 3 European universities were recruited through convenience and purposive sampling for exploratory interviews. A subsequent case study of the Open University provided critical perspectives from both educators (n=18) and learners (n=22) about the institutional, departmental, domain-related and epistemological factors that broadly infuence perceptions of learning analytics. The study applied "Affordance Theory" to identify what participants were most easily able to recognise as beneficial to their own practice. Participant contributions were open-coded to uncover emerging themes and then organised into thematic categories and subcategories. Respondent validation, as well as triangulation of data between the exploratory interviews and focus groups support the validity of the study. Findings suggested that domain-related epistemological assumptions and previous experience influence how and why an individual could make use of learning analytics insights. Gaining stakeholder acceptance involves targeting the right training and opportunities at the appropriate disciplines. Findings also indicate that learning analytics has the strongest mediatory effect for learners when the technology is capable of exposing them to other learners' strategies, or when it assists them personally, and continually in goal orientation adoption. The implications of the study are important for higher education institutions looking to implement large-scale learning analytics initiatives, in particular, those with a diverse student body.

description: Commercial cultivation of broccoli (Brassica oleracea cv. italica Plenck) is not widely practiced in the Eastern Caribbean in spite of a modest but steady demand which is satisfied by imports. Development of heat-tolerant commercial varieties in recent years has encouraged some ad hoc attempts at commercial production based on individual farmer experience and seed catalogue ratings especially in relation to varietal adaptability. Evaluation of nine currently available commercial varieties, and field observations on the performance of a few others, have indicated good levels of adaptability of most varieties for year round production, and the ability of most varieties to head satisfactorily in the cool season. Yields of over lO,OOO kg ha-l were recorded for most varieties, but three entries-- Early Value, Southern Comet and GreenTop--were outstanding for yield and head size. Green Comet, the standard variety, also produced well and rated highest for head uniformity. Earlier maturing varieties seem to have an advantage under the erratic environmental conditions of the region.

description: As the global population is aging, neurodegenerative diseases are becoming more and more of an issue. The treatments that exist today attack symptoms rather than going for the underlying causes. The research presented in this paper shows a novel application of Ashwagandha: a holistic alternative and one that has gained lots of attention for its neuroprotective, anti-inflammatory, and antioxidant properties.

description: We combine the Cosmic Lens All-Sky Survey (CLASS) with new Sloan Digital Sky Survey (SDSS) data on the local velocity dispersion distribution function of E/S0 galaxies, $ϕ(σ)$, to derive lens statistics constraints on $Ω_Λ$ and $Ω_m$. Previous studies of this kind relied on a combination of the E/S0 galaxy luminosity function and the Faber-Jackson relation to characterize the lens galaxy population. However, ignoring dispersion in the Faber-Jackson relation leads to a biased estimate of $ϕ(σ)$ and therefore biased and overconfident constraints on the cosmological parameters. The measured velocity dispersion function from a large sample of E/S0 galaxies provides a more reliable method for probing cosmology with strong lens statistics. Our new constraints are in good agreement with recent results from the redshift-magnitude relation of Type Ia supernovae. Adopting the traditional assumption that the E/S0 velocity function is constant in comoving units, we find a maximum likelihood estimate of $Ω_Λ= 0.74$--0.78 for a spatially flat unvierse (where the range reflects uncertainty in the number of E/S0 lenses in the CLASS sample), and a 95% confidence upper bound of $Ω_Λ<0.86$. If $ϕ(σ)$ instead evolves in accord with extended Press-Schechter theory, then the maximum likelihood estimate for $Ω_Λ$ becomes 0.72--0.78, with the 95% confidence upper bound $Ω_Λ<0.89$. Even without assuming flatness, lensing provides independent confirmation of the evidence from Type Ia supernovae for a nonzero dark energy component in the universe.
