description: Since the beginning of this decade there has been an interest in developing a passion fruit industry in Trinidad and Tobago (T&T) based on locally produced raw material. At present a few commercial ventures exist, but the scale of processing and related commercial activities, such as marketing, falls significantly short of what was originally envisaged. The major factor accounting for the slow «take-off» of this industry is raw material supply. This paper gives an account of the agronomic constraints encountered by passion fruit producers in T&T and describes the role of the University of the West Indies, Faculty of Agriculture , in addressing these problems. The collaborative efforts of the Caribbean Industrial Research Institute, other local research institutions and Government agencies to develop the industry are also discussed. ----- Depuis le début de cette décennie, il y a intérêt pour développer une industrie de la grenadille (fruit de la passion) à Trinidad et Tobago à partir de la matière première produite localement. Jusqu'à maintenant, il y a quelques entreprises commerciales mais l'échelle du traitement et les activités commerciales connexes sont en deçà des projets initiaux. Le principal facteur de ce lent «décollage» est la fourniture en matière première. Cette communication donne un bilan des contraintes agronomiques auxquelles sont confrontés les producteurs de grenadille à Trinidad et Tobago et décrit le rôle de la Faculté d'Agriculture de l'Université des West Indies dans l'approche de ces problèmes. Les efforts de collaboration entre l'Institut Caraïbe de Recherche Industrielle (CARIBI), d'autres institutions locales de recherche et des agences gouvernementales pour développer cette industrie sont aussi discutés.

description: Many materials quenched into their ordered phase undergo ageing and there show dynamical scaling. For any given dynamical exponent z, this can be extended to a new form of local scale-invariance which acts as a dynamical symmetry. The scaling functions of the two-time correlation and response functions of ferromagnets with a non-conserved order parameter are determined. These results are in agreement with analytical and numerical studies of various models, especially the kinetic Glauber-Ising model in 2 and 3 dimensions.

title: The ideology of Labourism and Britain's withdrawal from East of Suez
Creators: name: Williams, Geoffrey Lee
Publisher: name: The Open University
Year: 1978

description: This thesis seeks to examine the ideology of the Labour Party in relation to the Party's attitude towards Britain's role East of Suez since 1945. Both periods of office and opposition are examined in depth, although the major emphasis is on the period of office from October 1964 to June 1970. The ideology of Labourism is a synthesis of working-class politics and middle-class revisionism which became the basis of Labour's realpolitik in its foreign policy during and after the Second World War. Labour as a result of the influence of this ideology put nation before class. The leaders of the Labour movement aligned themselves - with a few notable exceptions - with all the national symbols of monarchy, judiciary and Parliament. They also identified themselves with the Commonwealth; an aspect central to this thesis because neither the utopian nor marxist left within the Labour Party found it expedient, or even moral, to fundamentally question the East of Suez role, until it was clear that it was inconsistent with Labour's ambitious social and economic programme. The imperial role was not at first rejected by the utopian and marxist left of the Party because it identified in the Commonwealth the basis of a possible neutralist foreign policy for Britain. When that proved a chimera the left repudiated the imperial role. The revisionist right and the Labourist centre regarded the East of Suez role as the basis of Britain's pretence to remain a great power. When that proved also a chimera the right repudiated the imperial role. This explains why the Labour leadership could embrace the imperial role with considerable enthusiasm and abandon it with alacrity when circumstances forced them to do so. Cultural Labourism and democratic socialist revisionism within the Labour Party became the dominant ideology of the Labour government but was not an ideology which encouraged a consistent attitude towards international politics. The myth that a Labour government meant a commitment to a socialist foreign policy- which can never be defined - even in principle, was however effectively destroyed. Labour in office indeed differed only from the Conservatives in the slight emphasis it occasionally gave to pursuing national policies which in the long-run - and perhaps therefore never - might assist in the re-structuring of the international system.
Quantum interference of ultrastable twin optical beams

description: We report the first measurement of the quantum phase-difference noise of an ultrastable nondegenerate optical parametric oscillator that emits twin beams classically phase-locked at exact frequency degeneracy. The measurement illustrates the property of a lossless balanced beam-splitter to convert number-difference squeezing into phase-difference squeezing and, thus, provides indirect evidence for Heisenberg-limited interferometry using twin beams. This experiment is a generalization of the Hong-Ou-Mandel interference effect for continuous variables and constitutes a milestone towards continuous-variable entanglement of bright, ultrastable nondegenerate beams.

Von der Konvertierung über HTR, Textannotation, Named Entity Recognition, Normalisierung und Übersetzung bis hin zur Anwendungsentwicklung und Visualisierung bergen Large Language Models großes Potenzial zur Unterstützung (digitaler) Editionsprozesse. Obwohl digitale Werkzeuge und Technologien, einschließlich KI und LLM, wertvolle Hilfsmittel in der Forschung sind, ist es entscheidend zu betonen, dass sie nicht die fundamentale Bedeutung einer gründlichen und reproduzierbaren Methodik im Forschungsprozess ersetzen, genau so wenig wie die Interpretation der Ergebnisse durch Forscher:innen. Ihr Einsatz erfordert eine kritische Auseinandersetzung mit ökologischen Faktoren, rechtlichen Fragen in Bezug auf die rechtmässige Verwendung von Trainingsdaten bis hin zu Überlegungen zu Ethik und wissenschaftlicher Integrität in Bezug auf Reproduzierbarkeit und Transparenz.

title: Towards a framework for addressing diverse learners in international, English-medium, print-centred DE : a Zimbabwean case study
Creators: name: Creed, Charlotte
Publisher: name: The Open University
Year: 2000

description: This study examines an increasingly common distance learning context: where tertiary level and English-medium DE courses are produced, tutored and examined in one country but studied by learners in other countries and who have English as an additional language.Empirical work is drawn from a case-study of agricultural extension officers in disparate parts of Zimbabwe undertaking a professional development course which is produced and mainly tutored in the distant UK.

This long-distance cross-cultural writing relationship between academics and students serves as a basis for the examination of difficulties created by taken-for-granted educational practices embedded in the course structure and materials, particularly in relation to language and academic literacy. The study examines contemporary debates around internationalised learning, including cultural and linguistic imperialism and the desirability of locally-produced courses, and provides an insight into black Zimbabwean perspectives on them. It explores a variety of contextual issues including the wider significance of DE in a southern African context, gendered learning patterns, the linguistic repertoire of the students and their academic literacy background.

Drawing on grounded theory, discourse analysis, literacy as social practice and genre theories,this overseas research aims to provide the UK course producers with insight into some of the particularities of the Zimbabwean learning context and some of the learning and teaching resources which exists beyond their control and ambit. It is hoped that more multi-faceted image of some of their learners may help course producers consider more closely the differences and commonalities between course participants; it may challenge the normative pedagogy embedded in the course and prompt the producers to consider appropriate responses;it may raise the policy question of how to establish, within an asymmetrical donor-recipient situation, a north-south academic relationship of an emancipatory kind.

These aims spring from the conviction that as we move towards globalised educational contexts, dominated by market leaders, significant changes and improvements in educational practice are more likely to come about as a result of an emerging reflexivity on the part of the course producers. Learners and importers of course may not have much influence over such decisions.

description: Viele Studien zeigen, dass Miscanthus (MSC) im Vergleich zum klassischen Ackerbau ökonomisch vorteilhaft sein kann. Dennoch bauen Landwirte nur vereinzelt MSC an. Es hat daher den Anschein, dass Landwirte der traditionellen Investitionstheorie nicht folgen. Im Unterschied zur traditionellen Investitionstheorie berücksichtigt der Realoptionsansatz (ROA) Irreversibilität und zeitliche Flexibilität einer Investition sowie die Unsicherheit hinsichtlich der Rückflüsse. Aus diesem Grund können die Investitionstrigger des ROA, ab denen ein Entscheider investieren sollte, höher als die der traditionellen Investitionstheorie sein. Häufig wird daraus in nicht MSC-Kontexten geschlussfolgert, dass der ROA Investitionszurückhaltung erklären kann. In vielen Anwendungen wird allerdings die Desinvestitionsmöglichkeit vernachlässigt. Es besteht daher die Gefahr, dass die gemäß ROA berechneten Investitionstrigger überhöht sind. Wir sind die ersten, die den ROA auf die Umstellungsmöglichkeit von klassischem Ackerbau auf MSC anwenden und mit Hilfe einer Kombination aus genetischem Algorithmus und stochastischer Simulation Investitions- bzw. Umstellungstrigger (mit und ohne Rückumstellungsmöglichkeit) bestimmen. Unsere Ergebnisse zeigen, dass die Umstellungstrigger des ROA bedeutend höher sind als die der traditionellen Investitionstheorie. Allerdings führt die Vernachlässigung der Rückumstellungsmöglichkeit zu einer Überschätzung der Umstellungszurückhaltung. Ein zunehmender Grad an Risikoaversion führt zu einer Verringerung der Umstellungstrigger beider Theorien. Es kann geschlussfolgert werden, dass der ROA die Zurückhaltung der Landwirte bei der Umstellung auf MSC zumindest teilweise erklären kann.

description: Studying the atmospheric Planetary Boundary Layer (PBL) is crucial to understand the climate of a planet. The meteorological measurements by the instruments onboard InSight at a latitude of 4.5$^{\circ}$N make a uniquely rich dataset to study the active turbulent dynamics of the daytime PBL on Mars. Here we use the high-sensitivity continuous pressure, wind, temperature measurements in the first 400 sols of InSight operations (from northern late winter to midsummer) to analyze wind gusts, convective cells and vortices in Mars' daytime PBL. We compare InSight measurements to turbulence-resolving Large-Eddy Simulations (LES). The daytime PBL turbulence at the InSight landing site is very active, with clearly identified signatures of convective cells and a vast population of 6000 recorded vortex encounters, adequately represented by a power-law with a 3.4 exponent. While the daily variability of vortex encounters at InSight can be explained by the statistical nature of turbulence, the seasonal variability is positively correlated with ambient wind speed, which is supported by LES. However, wind gustiness is positively correlated to surface temperature rather than ambient wind speed and sensible heat flux, confirming the radiative control of the daytime martian PBL; and fewer convective vortices are forming in LES when the background wind is doubled. Thus, the long-term seasonal variability of vortex encounters at the InSight landing site is mainly controlled by the advection of convective vortices by ambient wind speed. Typical tracks followed by vortices forming in the LES show a similar distribution in direction and length as orbital imagery.

description: Woody biomass in terms of short rotation coppice (SRC) could be a promising alternative for producing biomass to generate renewable energy. Even through, from a single farms point of view, SRC seems to be an interesting land use alternative, farmers do not cultivate SRC. Some studies found out that the real options approach (ROA) could at least partially explain farmers’ inertia of cultivating SRC. Nevertheless, those studies do not take into account market competition between farmers and farmers’ fear of not having an outlet market in order to dispose the harvested wood chips. This inertia can also cause an investment reluctance concerning building biomass heating stations. In the present study therefore, we focuses on the whole value chain from producing wood chips over generating energy and selling the energy to the end-consumers. We develop an agent-based model which is able to consider market competition and can picture the whole value chain. In order to further motivate farmers to cultivate SRC different types of incentives offered by the biomass heating station are investigated. Our results show that if no incentive system is offered, farmers cultivate SRC reluctantly which leads to a loss of profit of the biomass heating station. With regard to an investment subsidy, it needs to be equal to approximately 300% of the capital costs of investment to strongly motivate farmers to produce enough wood chips that largely decrease the loss of profit of the biomass heating station. If a price floor is offered, farmers’ additional amount of wood chips produced is very small. Therefore, the loss of profit does not significantly decrease if the price floor amounts to 95%.

description: Computational modeling is becoming a widely used methodology in modern neuroscience. However, as the complexity of the phenomena under study increases, the analysis of the results emerging from the simulations concomitantly becomes more challenging. In particular, the configuration and validation of brain circuits involving learning often require the processing of large amounts of action potentials and their comparison to the stimulation being presented to the input of the system. In this study we present a systematic work-flow for the configuration of spiking-neuronal-network-based learning systems including evolutionary algorithms for information transmission optimization, advanced visualization tools for the validation of the best suitable configuration and customized scripts for final quantitative evaluation of the learning capabilities. By integrating both grouped action potential information and stimulation-related events, the proposed visualization framework provides qualitatively assessment of the evolution of the learning process in the simulation under study. The proposed work-flow has been used to study how receptive fields emerge in a network of inhibitory interneurons with excitatory and inhibitory spike-timing dependent plasticity when it is exposed to repetitive and partially overlapped stimulation patterns. According to our results, the output population reliably detected the presence of the stimulation patterns, even when the fan-in ratio of the interneurons was considerably restricted.

description: There have been a number of claims in the literature about gravity shielding effects of superconductors and more recently on the weight reduction of superconductors passing through their critical temperature. We report several experiments to test the weight of superconductors under various conditions. First, we report tests on the weight of YBCO and BSCCO high temperature superconductors passing through their critical temperature. No anomaly was found within the equipment accuracy ruling out claimed anomalies by Rounds and Reiss. Our experiments extend the accuracy of previous measurements by two orders of magnitude. In addition, for the first time, the weight of a rotating YBCO superconductor was measured. Also in this case, no weight anomaly could be seen within the accuracy of the equipment used. In addition, also weight measurements of a BSCCO superconductor subjected to extremely-low-frequency (ELF) radiation have been done to test a claim of weight reduction under these conditions by De Aquino, and again, no unusual behavior was found. These measurements put new important boundaries on any inertial effect connected with superconductivity - and consequently on possible space related applications.

description: The D0 experiment at Fermilab relies on a central Oracle database for storing all detector calibration information. Access to this data is needed by hundreds of physics applications distributed worldwide. In order to meet the demands of these applications from scarce resources, we have created a distributed system that isolates the user applications from the database facilities. This system, known as the Database Application Network (DAN) operates as the middle tier in a three tier architecture. A DAN server employs a hierarchical caching scheme and database connection management facility that limits access to the database resource. The modular design allows for caching strategies and database access components to be determined by runtime configuration. To solve scalability problems, a proxy database component allows for DAN servers to be arranged in a hierarchy. Also included is an event based monitoring system that is currently being used to collect statistics for performance analysis and problem diagnosis. DAN servers are currently implemented as a Python multithreaded program using CORBA for network communications and interface specification. The requirement details, design, and implementation of DAN are discussed along with operational experience and future plans.

description: Botnets are now a major source for many network attacks, such as DDoS attacks and spam. However, most traditional detection methods heavily rely on heuristically designed multi-stage detection criteria. In this paper, we consider the neural network design challenges of using modern deep learning techniques to learn policies for botnet detection automatically. To generate training data, we synthesize botnet connections with different underlying communication patterns overlaid on large-scale real networks as datasets. To capture the important hierarchical structure of centralized botnets and the fast-mixing structure for decentralized botnets, we tailor graph neural networks (GNN) to detect the properties of these structures. Experimental results show that GNNs are better able to capture botnet structure than previous non-learning methods when trained with appropriate data, and that deeper GNNs are crucial for learning difficult botnet topologies. We believe our data and studies can be useful for both the network security and graph learning communities.

Phuphania

description: Phuphania, new genus
  Type species. – Phuphania globosa , new species.
 Diagnosis. – The key generic characters distinguishing Phuphania from other genera in the Dyakiidae are those of the amatorial organ: possession of small ducts clustered within the amatorial organ gland and fused lobes forming a cap over the amatorial organ. The amatorial organ of Phuphania most closely resembles those of Kalamantania and Everettia but in these genera the gland consists of few lobes, each entering the amatorial organ apically. In Bertia the amatorial organ is composed of many tightly packed lobes; each lobe with an individual duct apically entering the amatorial organ.
 Etymology. – ‘ Phuphania ’ from the Phu (= Mountain) Phan range, the type locality.

description: Fish populations depend on suitable spawning habitats, and species like salmon and trout require specific substrate conditions for successful reproduction. Instream boulders enhance habitat heterogeneity by creating depressions and riffle spots that provide well-oxygenated gravel beds for egg deposition and predator refuge. Restoration projects often use rock-ramp boulder arrangements to improve habitat functionality. This study experimentally investigated the relationship between instream boulder placement, bed erosion, and sediment deposition to assess spawning habitat suitability. A total of 18 scenarios were tested, varying boulder concentrations (λ = 0 to 8.30%) across three bed slopes (0.5%, 1.0%, and 1.5%). Findings indicate that lower boulder densities result in minimal local scour depth and sediment transport, creating favorable spawning conditions for salmonids. These results provide valuable insights for habitat restoration efforts, guiding optimal boulder placement and concentration to enhance spawning success while maintaining streambed stability.
In the absence of fiscal union, the Eurozone needs a more flexible monetary policy

description: This paper makes three points. The first is that external imbalances between Member States are relevant for the performance of a monetary union when the latter is not backed by a strong political commitment and a solid political framework. Eurozone policymakers have ignored these inter-member imbalances and have instead concentrated on union-wide imbalances, so much so that statistical data on the former phenomenon still remain largely incomplete. There are signs that a correction is in the making, which we hope will lead to a comprehensive quantitative knowledge of intra-EMU imbalances. The second objective of the paper is to design specific policies aimed at reducing inter-member external disequilibria, for example by fixing targets on current-account imbalances symmetrically applied to both deficit and surplus countries. The contrast between the keen attention of the EZ policymakers on national fiscal imbalances and the belated and lukewarm attention given to external imbalances is striking. The third aim of the paper is to propose a more flexible monetary policy aimed at controlling the distribution of liquidity among Member States, resulting from inter-member external imbalances. Our proposal is that National Central Banks should add a risk premium cost to official interest rates on banks that accumulate “excessive” borrowings or deposits to compensate, respectively, for outflows and inflows of the monetary base due to the effect of external imbalances.

description: Financial institutions still neglect to address agricultural clients. The main reasons for that are their perception that farmers bear higher risks than non-farmers and that their loan products are inadequate to accommodate the needs of agricultural entrepreneurs. As a result, many farmers still lack access to external finance. The aim of this paper is to investigate determinants of credit risk for agricultural loans disbursed by a Microfinance Institution (MFI) in Azerbaijan. In this context special attention is paid to repayment flexibility and the role of collaterals. MFIs are among the first financial institutions recently focusing on farmers with new loan products. We find that farmers are less risky than non-farmers, which is surprising because the opposite is widely believed. We furthermore find that the level of collateral has a negative influence on credit risk. Beyond that, we find that repayment flexibility increases credit risk.

description: We propose a new pressure-based structure-preserving (SP) and quasi asymptotic preserving (AP) staggered semi-implicit finite volume scheme for the unified first order hyperbolic formulation of continuum mechanics. The unified model is based on the theory of symmetric-hyperbolic and thermodynamically compatible (SHTC) systems and includes the description of elastic and elasto-plastic solids in the nonlinear large-strain regime as well as viscous and inviscid heat-conducting fluids, which correspond to the stiff relaxation limit of the model. In the absence of relaxation source terms, the homogeneous PDE system is endowed with two stationary linear differential constraints (involutions), which require the curl of distortion field and the curl of the thermal impulse to be zero for all times. In the stiff relaxation limit, the unified model tends asymptotically to the compressible Navier-Stokes equations. The new structure-preserving scheme presented in this paper can be proven to be exactly curl-free for the homogeneous part of the PDE system, i.e. in the absence of relaxation source terms. We furthermore prove that the scheme is quasi asymptotic preserving in the stiff relaxation limit, in the sense that the numerical scheme reduces to a consistent second-order accurate discretization of the compressible Navier-Stokes equations when the relaxation times tend to zero. Last but not least, the proposed scheme is suitable for the simulation of all Mach number flows thanks to its conservative formulation and the implicit discretization of the pressure terms.
The Effect of Star Formation History on the Inferred Initial Stellar Mass Function

description: Peaks and lulls in the star formation rate (SFR) over the history of the Galaxy produce plateaux and declines in the present day mass function (PDMF) where the main-sequence lifetime overlaps the age and duration of the SFR variation. These PDMF features can be misinterpreted as the form of the intrinsic stellar initial mass function (IMF) if the star formation rate is assumed to be constant or slowly varying with time. This effect applies to all regions that have formed stars for longer than the age of the most massive stars, including OB associations, star complexes, and especially galactic field stars. Related problems may apply to embedded clusters. Evidence is summarized for temporal SFR variations from parsec scales to entire galaxies, all of which should contribute to inferred IMF distortions. We give examples of various star formation histories to demonstrate the types of false IMF structures that might be seen. These include short-duration bursts, stochastic histories with log-normal amplitude distributions, and oscillating histories with various periods and phases. The inferred IMF should appear steeper than the intrinsic IMF over mass ranges where the stellar lifetimes correspond to times of decreasing SFRs; shallow portions of the inferred IMF correspond to times of increasing SFRs. If field regions are populated by dispersed clusters and defined by their low current SFRs, then they should have steeper inferred IMFs than the clusters. The SFRs required to give the steep field IMFs in the LMC and SMC are determined. Structure observed in several determinations of the Milky Way field star IMF can be accounted for by a stochastic and bursty star formation history.

Perturbative study of concentric 5-branes in plane-wave matrix model and development of mathematical formalism for wigner j-symbols

description: Expansion and computation of quantities around various (k x N) x (k x N) vacuua in BMN theory results in introduction of Matrix spherical harmonics and various traces of their products. In this thesis the formalism to deal with these harmonics is developed and a few bosonic diagrams that arise in computation of Tr(XªXª) are computed as an example. It is then seen that the large N limit is dominated by a planar subclass of these diagrams with a particular topology. This suggests a stronger constraint than that of 't Hooft.
Shadow banking, relationship banking, and the economics of depression

description: The paper explores whether a theory of banks doing ‘finance through money creation’ implies a reconsideration of demand-side macro theory as well. To this aim, a simple methodological accounting model of the influence of financial markets over the real economy is presented. The model allows a tidy comparison of relationship and shadow banking, interpreted as alternative schemes of liquidity (not credit) risk management. The model emphasizes the interdependencies in entrepreneurs’ animal spirits, liquidity risk management schemes adopted by financial institutions, and effective demand of households. The underlying idea is that fluctuations in the composition of property incomes trigger fluctuations in non-financial investment that, in turn, drive fluctuations in spending. The article finds that both relationship and shadow banking must have a pro-cyclical impact, and differences are essentially based on different liquidity risk management aggregate cost functions. The model developed here suggests that securitisation does not per se affect the financial sustainability of the growth process, but regulatory measures aimed at checking predatory lending and re-securitisation activities are needed to avoid possible adverse impacts on animal spirits.

description: Equilibrium sedimentation density profiles of charged binary colloidal suspensions are calculated by computer simulations and density functional theory. For deionized samples, we predict a colloidal ``brazil nut'' effect: heavy colloidal particles sediment on top of the lighter ones provided that their mass per charge is smaller than that of the lighter ones. This effect is verifiable in settling experiments.
