description: Abstract: Peat moss cultivation to substitute white peat as an irreplaceable resource in commercial horticulture was investigated in the project „peat moss as renewable resource“(2004-2007). With a first field experimental site (~1000 m2) applied implementation was tested near Cloppenburg (Northwest of Lower Saxony). Fragments of Sphagnum papillosum were spread and covered with straw mulch. Under these conditions peat mosses established and cultivation appears feasible. Peat moss productivity after growth period of 3 years was lower than that under green house conditions in the project and compared to published data. Straw cover (characterized by cover (%) and thickness (cm)) varied spatially due to manual spreading. Growth of peat mosses and the herb layer was negatively correlated with the thickness of straw cover. Spatial variation in peat moss growth were documented which could not be explained by variables measured in the study. While a peat moss lawn was successfully established in the 3 year field experiment, upscaling peat moss cultivation will face challenges that are currently poorly understood.
description: Zusammenfassung: Im Projekt „Torfmoos als nachwachsender Rohstoff“ (2004-2007) wurde die Torfmooskultivierung zur Gewinnung eines weißtorfadäquaten Substratrohstoffs für den Erwerbsgartenbau untersucht. Anhand eines ersten Feldversuchs (~1000 m2) in der Nähe von Cloppenburg (Nordwest Niedersachsen) wurde die praktische Umsetzung erprobt. Fragmente von Sphagnum papillosum sind hierfür manuell verteilt und anschließend mit Stroh bedeckt worden. Es hat sich gezeigt, dass eine Etablierung von Torfmoosen unter den gegebenen Bedingungen möglich ist. Die Produktivität ist nach 3 Jahren Versuchsdauer geringer als in Gewächshausversuchen des Projekts und auch geringer im Vergleich zu Literaturdaten. Die Strohbedeckung (charakterisiert durch Deckung in % und Mächtigkeit in cm) variiert durch die manuelle Verteilung. Das Wachstum der Torfmoose und der Krautschicht sind negativ korreliert mit der Strohbedeckung zu Beginn des Versuchs. Die räumliche Variabilität des Torfmooszuwachses kann zurzeit noch nicht vollständig erklärt werden. Trotz der erfolgreichen Etablierung eines Torfmoosrasens innerhalb von 3 Jahren bleiben noch viele Fragen zur großflächigen Umsetzung der Torfmooskultivierung offen.

description: In a certain kinematic limit, where the effects of spacetime curvature (and other background fields) greatly simplify, the light-cone gauge world-sheet action for a type IIB superstring on AdS_5 x S^5 reduces to that of a free field theory. It has been conjectured by Berenstein, Maldacena, and Nastase that the energy spectrum of this string theory matches the dimensions of operators in the appropriately defined large R-charge large-N_c sector of N=4 supersymmetric Yang--Mills theory in four dimensions. This holographic equivalence is thought to be exact, independent of any simplifying kinematic limits. As a step toward verifying this larger conjecture, we have computed the complete set of first curvature corrections to the spectrum of light-cone gauge string theory that arises in the expansion of AdS_5 x S^5 about the plane-wave limit. The resulting spectrum has the complete dependence on lambda = g_YM^2 N_c; corresponding results in the gauge theory are known only to second order in lambda. We find precise agreement to this order, including the N=4 extended supermultiplet structure. In the process, we demonstrate that the complicated schemes put forward in recent years for defining the Green--Schwarz superstring action in background Ramond-Ramond fields can be reduced to a practical (and correct) method for quantizing the string.

Evaluating Peace Education in the Oslo-Intifada Generation: A Long-Term Impact Study of Seeds of Peace 1993-2010
Creators: name: Lazarus, Edward
Publisher: name: American University
Year: 2023

description: Since 1993, several thousand Israeli and Palestinian youth have participated in 12 summer "coexistence" programs in North America. The programs espouse a common theory of change: that an experience of dialogue in an idyllic American setting will inspire youth to return to the Middle East as aspiring peacemakers. This dissertation provides the first large-scale, long-term empirical assessment of that theory, by tracking the peacebuilding activity of all 824 Israeli and Palestinian graduates of SOP's first decade of operation (1993-2003), and complementing this with qualitative research on more than 100 adult graduates (ages 21-30). The longitudinal framework assesses fluctuations in activity over time, highlighting the influence of changing personal, organizational, and political contexts. Key findings include that more than half of alumni engaged in peacebuilding during high school; that compulsory Israeli military service discouraged activity among both Israeli and Palestinian graduates; that nearly one-fifth of alumni engaged in peacebuilding as adults; and that extensive follow-up programming was essential for sustaining long-term commitments to peacebuilding. The study concludes that the international intervention structure embeds an effective educational model in a problematic organizational model. While providing an unprecedented evaluation of a popular peace education approach, this study tells the stories of a pivotal generation: Palestinians and Israelis who entered adolescence at the hopeful dawn of the Oslo peace process, to emerge as adults in an era of intifada and "separation."

description: Die zunehmende Verwendung von Torfen aller Zersetzungsgrade und Gewinnungsverfahren zur Bodenverbesserung und Substratherstellung macht es erforderlich, daß für die Beurteilung der Materialeigenschaften, insbesondere der physikalischen Eigenschaften, die Werte nach einer Methode ermittelt werden. Wichtig ist dabei, daß die in der Praxis auftretenden Verhältnisse mit dieser Methode zu erfassen sind. Für eine Anzahl auf dem Markt befindlicher Substratzuschlagstoffe wurden die physikalischen Eigenschaften bestimmt. Es bestätigte sich dabei, daß eine Verbesserung der physikalischen Eigenschaften von wenig zersetztem Torf nicht erforderlich und möglich ist. Die stärker zersetzten Torfe bedürfen für einige Anwendungsgebiete, z.B. Kultursubstrate, einer Zumischung von wenig zersetztem Torf oder eines anderen Zuschlagstoffes. Viele Kulturmaßnahmen im Pflanzenbau, wie Bewässerung, Düngung und Pflanzenschutz, können nur bei optimalen physikalischen Eigenschaften der Substrate Voll zur Wirkung kommen.
description: In horticulture, so for soil improvement and substrates, different types of peat as to the degree of decomposition and the method of winning are more and more used. Therefore it is necessary to use only one technique for the determination of the physical properties, whereby it is of importance to keep in mind the conditions which occur in practical use. For a number of commercial substrates and additives the physical properties were determined. It is shown that it is not possible to improve low-decomposed peat. The more decomposed peat-types however, when used as substrates, need an admixture of some low-decomposed peat or of other additives, as many operations in horticulture, for example irrigation, fertilization and application of pesticides, develop their full effect only when the physical properties of the substrates are optimal.

Feynman gave an important contribution to this formulation conjecturing a crucial mathematical relation which completed Kac and Ward ideas. In this paper, the method of Kac, Ward and Feynman for the free field Ising model in two dimensions is reviewed in a selfcontained way.

description: In this article, the influence of using strategic inventory and forming collusion between upstream manufacturers and downstream retailers is studied when two competing supply chains offer substitutable products in a common market through exclusive retailers. The optimal pricing decisions are explored in five different scenarios. It is found that with a specific limit of holding cost, the retailer can carry inventory strategically for the benefit of each member when upstream manufacturers have a first-mover advantage. Two-period planning can outperform a single-period decision. However, if two downstream retailers form collusion and uphold strategic inventory, the profit share of upstream manufacturers can reduce considerably, but the sales volume of both supply chains increased. In that circumstance, retailers rely upon more strategic inventory, and manufacturers need to drop their respective wholesale prices considerably in the second period. A long-term wholesale price commitment contract is used to safeguard the interest of upstream manufacturers. We find that the proposed mechanism can improve the performance of all the members. Numerical experiments provide valuable managerial insights regarding the supply chain members’ strategic decisions under competition.

description: Succession Planning is a concept that is becoming more necessary within organizations, especially non-profit arts organizations that have had a leader in their position for more than 25 years. The Studio Theatre in Washington, D.C., recently underwent a leadership transition of the Artistic Director position; a position that was, up until the transition, filled by a Founder who had been in the position for over 35 years. Founder-driven non-profit arts organizations tend to follow a certain pattern that sometimes described as "Founder's Syndrome," where the Founder tries to maintain all control of the organization and its departments. This project researches succession plan theories and analyzes these against the real-life case study of The Studio Theatre's succession plan and its execution.
Serine/threonine phosphorylation in Mycobacterium tuberculosis : substrates of PknH kinase
Creators: name: Zheng, Xingji
Publisher: name: University of British Columbia
Year: 2011

description: Tuberculosis is a major cause of premature mortality world wide. Nevertheless, we have very limited understanding of the physiology of its causative agent M. tuberculosis. This thesis focuses on M. tuberculosis PknH kinase and signal transduction cascade mediated by it. PknH kinase is a fascinating kinase to study because it was shown to mediate reduced M. tuberculosis growth in vivo through sensing of nitric oxide. Identification of PknH signal transduction cascade can lead to better understanding of M. tuberculosis physiology during infection. The only known phosphorylation substrate of PknH to date is a transcription factor EmbR. It is know to regulate transcription of cell wall production genes. It seemed unlikely that EmbR, the only known PknH substrate, alone can mediate such complex reaction during infection. Therefore, we hypothesized that PknH kinase must phosphorylates multiple substrates, other than EmbR. And the phosphorylation sites on the substrates are similar to the autophosphorylation site on PknH kinase. We were able to visualize 9 PknH specific phospho-proteins by two-dimensional phosphor-proteome analysis. Alternatively, using a bioinformatic approach we predicted 40 potential PknH phosphorylation substrates. Two of the predicted substrates were selected for further studies. In vitro kinase studies concluded both Rv0681 and DacB1 are phosphorylated by PknH kinase, and point mutation studies confirmed that PknH kinase phosphorylates both substrates at predicted sites. We also performed enzyme kinetic studies to compare PknH phosphorylation of 3 different substrates. The results revealed that PknH is able to phosphorylate Rv0681 and DacB1 with much higher enzyme velocity than EmbR; but EmbR exhibited much higher Km value than Rv0681 and DacB1. The results presented in this thesis suggest that DacB1 and Rv0681 are true phosphorylation targets of PknH kinase; and the interaction between kinase and substrates are more complex than we initially thought.

description: We present a modelling framework for the investigation of supervised learning in non-stationary environments. Specifically, we model two example types of learning systems: prototype-based Learning Vector Quantization (LVQ) for classification and shallow, layered neural networks for regression tasks. We investigate so-called student teacher scenarios in which the systems are trained from a stream of high-dimensional, labeled data. Properties of the target task are considered to be non-stationary due to drift processes while the training is performed. Different types of concept drift are studied, which affect the density of example inputs only, the target rule itself, or both. By applying methods from statistical physics, we develop a modelling framework for the mathematical analysis of the training dynamics in non-stationary environments. Our results show that standard LVQ algorithms are already suitable for the training in non-stationary environments to a certain extent. However, the application of weight decay as an explicit mechanism of forgetting does not improve the performance under the considered drift processes. Furthermore, we investigate gradient-based training of layered neural networks with sigmoidal activation functions and compare with the use of rectified linear units (ReLU). Our findings show that the sensitivity to concept drift and the effectiveness of weight decay differs significantly between the two types of activation function.

The method is based on a simple regularization procedure, imposing an additional constraint on the constructed potential curve. In the present work it is applied to the double minimum 4$^1Σ^{+}_{\mathrm u}$ state of Na$_2$, observed experimentally by polarization labeling spectroscopy technique.

title: Biophysical studies of TIMP-1
Creators: name: Hodges, Deborah Jane
Publisher: name: The Open University
Year: 1995

description: This study had two aspects. The first was the production and purification of TIMP-l. The second was a series of biophysical studies of TIMP-l and a TIMP-l derived peptide. A monoclonal antibody affinity column was developed and used to purifY large quantities of human TIMP-l for further experiments. Two E.coli expression systems were studied to determine whether they would be suitable for large scale production of recombinant protein. In the first system TIMP-I was to be secreted as a fusion protein which could be cleaved, leaving a free N-terminus. It was discovered that it was not possible to cleave off the fusion protein. In the second system, the protein was secreted, without additions to the periplasm. Although active protein, with the correct N-tenninus, was obtained, the yields were too low to be of use for large scale expression. Secondary structure analysis by CD and FTIR showed TIMP-l to be a mostly f3- sheet protein (approaching 50%) with around 20% a-helix. A temperature study using these techniques found that little change occurs until temperatures of over 60°C where the protein aggregates. The small changes appear to be a general loosening of the structure. In analyses of the surface of TIMP-l, additional carbohydrate was identified (other than the two N-linked chains) using Con-A probing of Western blots. TIMP-l purified from WI-38 foetal lung fibroblast cells can be separated into two pools by Concanavalin A-Sepharose chromatography. These two pools were found to have a different set of pIs and a different monosaccharide composition. The use of NMR paramagnetic probes identified a hydrophobic region exposed on the surface of TIMP-I. This region probably includes a tyrosine residue and either a tryptophan or phenylalanine. The presence of an exposed hydrophobic region was also shown in binding studies using the fluorescent probe ANS. These studies identified a single, low affinity binding site. An additional study with the N-terminal fragment of type-I collagenase found no binding sites on the enzyme, but a change in fluorescence occurred when TIMP-I was present. A peptide was designed based on the N-terminal sequence of TIMP-I. High homology, susceptibility to mutation and an interesting resemblance to the Bowman-Birk family of inhibitors suggested that this peptide might be inhibitory. It was found to have only a weak inhibitory activity against gelatinase. NMR studies of this peptide in water showed a large number of conformers as a result of stabilisation of the cis isomer of its proline residues. This preference for the cis form was retained for one proline in the solvent, TFE. Preliminary NMR studies were also carried out which concluded that TIMP-I should be suitable for further structural studies using isotopic labelling.

description: In order to test a possible evolutionary scenario of high-$z$ compact quiescent galaxies (cQGs) that they can survive as local compact cores embedded in local massive galaxies with different morphology classes, we explore the star formation histories of local compact cores according to their spectral analysis. We build a sample of 182 massive galaxies with compact cores (${M}_{*,{\rm core}} > 10^{10.6} {\rm M}_\odot$) at $0.02 \leq z \leq 0.06$ from SDSS DR7 spectroscopic catalogue. STARLIGHT package is used to analyze the median stacked spectra and derive the stellar ages and metallicities. Our main results show that local compact cores have the average age of about $12.1\pm0.6$ Gyr, indicating their early formation at $z > 3$, which is consistent with the formation redshifts of cQGs at $1 80\%$) will evolve into local massive ETGs according to dry minor merger, while some of them ($\sim 15\%$) will build a substantial stellar/gas discs according to the late-time gas accretion and sustaining star formation, and finally grow up to spiral galaxies.

description: Heute gibt es in den Niederlanden noch etwa 8800 ha Hochmoorreste. Durch Entwässerung, Abtorfung und Brand sind die meisten Hochmoorreste weitgehend zerstört worden und ist die ursprüngliche Hochmoorvegetation fast überall völlig verschwunden. Seit etwa 1970 werden in mehreren Hochmoorresten Pflege- und Gestaltungsmaßnahmen durchgeführt, um die Wiederherstellung einer moorbildenden Vegetation zu versuchen. Es handelt sich dabei vor allem um Maßnahmen zur Wiedervernässung. Über diese Maßnahmen und ihren Einfluß auf die Vegetationsentwicklung wird berichtet. Weiterhin werden die Faktoren diskutiert, die eine Entwicklung von Hochmoor-Pflanzengemeinschaften verhindern können. Dabei bleiben viele Fragen offen, die ohne weitere Untersuchungen nicht zu beantworten sind.
description: In the Netherlands only 8800 ha of the former raised-bog complexes are still existing. In these remaining peat-deposits the former natural conditions are strongly disturbed as a result of human activities such as drainage, peatcutting and burning. Since about 1970 in several peatlands attempts have been made to restore environmental conditions suitable for the re-establishment of the former bog-vegetation. The most important activity is raising the water level, thus creating extreme wet conditions. In this article some of these attempts and their effect on the development of the vegetation are described. Several environmental conditions which might diminish the possibilities for the re-establishment of raised-bog vegetation are discussed.

description: When a quantum nonlinear system is linearly coupled to an infinite bath of harmonic oscillators, quantum coherence of the system is lost on a decoherence time-scale $τ_D$. Nevertheless, quantum effects for observables may still survive environment-induced decoherence, and be observed for times much larger than the decoherence time-scale. In particular, we show that the Ehrenfest time, which characterizes a departure of quantum dynamics for observables from the corresponding classical dynamics, can be observed for a quasi-classical nonlinear oscillator for times $τ\ggτ_D$. We discuss this observation in relation to recent experiments on quantum nonlinear systems in the quasi-classical region of parameters.

description: Die Kultivierung der Moore hat in Mitteleuropa, so auch in der Bundesrepublik Deutschland eine lange historische Entwicklung hinter sich. Früher wurden die Moore als Ödland gemieden, später als Siedlungsraum mit landwirtschaftlicher Nutzung und als Brennstofflieferant beansprucht. Heute werden sie als Torflagerstätte und Feuchtbiotop geschätzt und in den letzten Jahren haben sie für den Naturschutz zunehmend an Bedeutung gewonnen. Für das moorreichste Bundesland Niedersachsen liegen neue Erhebungen mit genauen Zahlen über die Nutzung der Nieder- und Hochmoore vor. Das Moorschutzprogramm - Teil 1 - der Niedersächsischen Landesregierung von 1981 dokumentiert die Bestrebungen, Hochmoorgebiete unter Schutz zu stellen. Diese Entwicklung am Beispiel Niedersachsens zeigt den allgemeinen Sinneswandel der Politiker bei der Hochmoornutzung. Dabei spielen heute rohstoffpolitische Überlegungen eine dem Naturschutzgedanken untergeordnete Rolle.
description: In Germany as well as in whole Central Europe the cultivation of mires has passed through a long historical development. In former times people kept away from these wastelands. Later, mires were reclaimed for agricultural and settlement purposes and for fuel supply. Today they are highly estimated as peat deposits on the one hand and as wetlands on the other. During the last years they became more and more important for nature conservation.

An Examination of Coping Strategies and Mindfulness as Predictors of Appearance Satisfaction and Body Image
Creators: name: MacKenzie, Kelly
Publisher: name: American University
Year: 2023

description: Body image involves beliefs, perceptions, and cognitions regarding the physical self. Research on the subject has found that body image concerns are associated with a variety of negative outcomes, and that positive body image is linked with greater overall well-being. The present study examined more specifically how positive and negative styles of coping relate to body image. Mindfulness, or non-judgmental acceptance and awareness, was also investigated as a potential correlate of body image. A total of 200 adults responded to an online questionnaire assessing body image, mindfulness, and coping. Results of correlation analyses indicated that body image, coping, and mindfulness are significantly related. Additional regression analyses found that coping styles significantly predicted positive and negative body image, and that mindfulness significantly predicted coping styles but not body image. These findings reveal potential mechanisms by which body image may be protected or improved, and have potential implications in treatment and research.

description: Elaeagnus latifolia is an underutilized plant of the Elaeagnaceae family. The extraction of E. latifolia pulp was carried out from 30 to 120 min by different environmentally friendly extraction methods: agitation, percolation, Soxhlet, and ultrasound-assisted extraction with ethanol, and hydrodistillation. The extracts were analyzed for their total phenolic compounds, carotenoids and ascorbic acid contents, and antioxidant activity. The highest yield of extract, of 63.5 g/100 g of raw material (RM), in dry basis (db), total phenolic compounds, of 3.3 mg gallic acid equivalent (GAE)/g extract, and 2.042 mg GAE/g RM, and carotenoids, of 176.6 mg β-carotene equivalent/kg RM, were obtained by Soxhlet for 120 min. All the extracts presented similar antioxidant activity. Therefore, E. latifolia can be a source of compounds of interest to the food industry.
title: Nationalism and transnationalism: the national conflict in Ireland and European Union integration
Creators: name: Goodman, James
Publisher: name: The Open University
Year: 1995

description: This study poses the question of why national conflicts persist in the context of increasing transnational integration. From the early 1970's and especially since the end of the 'Cold War', nationalism has gained increased global significance. At the same time, seemingly hand-in-hand with the upsurge in nationalism, there has been an acceleration in transnational integration. This apparent paradox is explored in several ways: first by developing a theoretical framework for linking nationalism and transnationalism, second by analysing a particular case of national conflict in its transnationalised setting, and third by investigating the interpretation and re-interpretation of 'national' interests by key political actors. The case chosen is the national conflict in Ireland in the context of transnational integration in the European Union. In Ireland the two global tendencies - of national division and transnational integration - are focussed to a high degree of intensity. The transnational integrative process is at its most advanced in the European Community which, in 1993, became the 'European Union', one of the most ambitious examples of inter-state and trans-state regional integration to date. The national conflict in Ireland meanwhile, is more deeply entrenched than in any other Western European state and was, until the IRA ceasefire on 31 August 1994, the most highly militarised conflict in Western Europe. This study suggests that the relationships between transnational integration and national conflict are becoming a defining factor in Ireland's political development and that such relationships also pattern developments in the wider EU. Indeed, to the extent that the process of EU integration is seen as an antidote to nationalism in Western Europe, the impact of the EU in Ireland's national conflict could be interpreted as a test case of EU integration.

description: A design concept for nanowire-based sensors and arrays is described. The fabrication technique involves electrodeposition to directly grow nanowires between patterned thin film contact electrodes. To prove our concept, we have electrodeposited 1-mm diameter Pd single wires and small arrays. To demonstrate nanowire sensors, we have electrochemically grown metal (Pd, Au, Pt), metal oxide (Sb2O3), and conducting polymer (polyaniline) bundled nanowires. Using Pt bundled nanowires surface modified with glucose oxidase, we have demonstrated glucose detection as a demonstration of a biomolecular sensor.

description: Seit Jahren und speziell nach Vollendung des europäischen Binnenmarktes nimmt der grenzüberschreitende Handel mit Waren aller Art zu.Der hiermit verbundene Bedarf an länderübergreifenden Normen steigt. Sie sollen helfen, technische Schranken abzubauen und den Markt der einzelnen Produktgruppen für den Verbraucher transparenter zu machen. Die Schaffung Europäischer Normen für Produkte aus dem Bereich Kultursubstrate und Bodenverbesserungsmittel ist in vollem Gang.Für Hersteller, Verbraucher und Labors werden nicht zu übersehende Änderungen kommen.
description: For years and in particular with the completion of the European Market trade between member states with commodities of every description in increasing. Thus the need for common standards to assist international trade is growing. They shall help overcome technical barriers and make the market for all product groups more transparent for the consumer. The establishment of European Standards for growing media and soil improves is now in full progress. Producers, consumers and laboratories must be aware of the coming changes.

description: We develop a general kinetic theory framework to describe the hydrodynamics of strongly interacting, nonequilibrium quantum systems in which integrability is weakly broken, leaving a few residual conserved quantities. This framework is based on a generalized relaxation-time approximation; it gives a simple, but surprisingly accurate, prescription for computing nonequilibrium transport even in strongly interacting systems. This approximation reproduces the crossover from generalized to conventional hydrodynamics in interacting one-dimensional Bose gases with integrability-breaking perturbations, both with and without momentum conservation. It also predicts the hydrodynamics of chaotic quantum spin chains, in good agreement with matrix product operator calculations.

An Examination of Coping Strategies and Mindfulness as Predictors of Appearance Satisfaction and Body Image

description: Body image involves beliefs, perceptions, and cognitions regarding the physical self. Research on the subject has found that body image concerns are associated with a variety of negative outcomes, and that positive body image is linked with greater overall well-being. The present study examined more specifically how positive and negative styles of coping relate to body image. Mindfulness, or non-judgmental acceptance and awareness, was also investigated as a potential correlate of body image. A total of 200 adults responded to an online questionnaire assessing body image, mindfulness, and coping. Results of correlation analyses indicated that body image, coping, and mindfulness are significantly related. Additional regression analyses found that coping styles significantly predicted positive and negative body image, and that mindfulness significantly predicted coping styles but not body image. These findings reveal potential mechanisms by which body image may be protected or improved, and have potential implications in treatment and research.
Where Culture Meets Development: Perspectives of Development Professionals in the Participatory Era

description: Conventional development practices, designed to promote modernization and economic integration, gave way to ideologies of participatory development in the 1990s. While participatory development, in theory, privileges the desires, and strategies of communities in the global South, and reflects local cultural practices, its success is limited. This thesis considers the perspectives of development professionals, and addresses the following questions: Given lessons learned from the failures of structural adjustment and other conventional practices, what barriers prevent development professionals from working with communities effectively in the participatory era? How do development professionals find meaning in their work, in spite of conflict and failure? Findings suggest that the interests of donors and employers, and a "professional culture" constrains practitioners, to the point that it is not possible for project beneficiaries to participate significantly. Fully aware of the problems of structure and agency pervading the field, practitioners adapt or leave, implying that there is little space for innovation in development institutions and organizations.

description: There is a clear and significant problem with the invasion of basin ecosystems by a wide array of biological agents impacting the social and economic systems, food supply, and unique environments. Basin members share both an interest in and dependency on trade with a great vulnerability to the inherent risks associated with it. Moreover, what threatens one generally is a threat to all. Mostly unilateral, occasional bilateral and few multilateral initiatives have been taken to cope with invasive alien species and more are in the planning stages. Now the challenge is how to take advantage of these initiatives and weave them into a strategic, coordinated set of actions to enhance prevention, exclusion, detection and management of highthreat agents basin-wide. Through this collective security approach, initiatives in regulation development, institution building, training, research, public affairs, and pest/disease/weed management would serve to strengthen safeguarding systems basin-wide.
Meeting G20 commitments

description: The G20 Leaders’ Summit in 2018 advocated a ‘high priority’ in early years, launching the G20 Initiative for Early Childhood Development (ECD), as ‘early childhood is one of the most significant and influential phases of life’. The UK was a signatory of this initiative. 

Our research demonstrates, however, that public spending in lower-  and middle-income countries does not deliver front-loaded investment in the early years of childhood.  In the UNICEF report Too Little Too Late, we mapped public spending on children by age in 84 countries. An update of our analysis ahead of the Rio G20 summit showed that in the African Union, on average just 6.5% of public spending on children was spent on the under-6s, compared to 30% in EU countries. This equates to just $865usd being spent per child until age 6 in Africa; $72,000usd per child is spent in the EU.

Spending less on the youngest directly contradicts the key principles of the G20 initiative. The UK had been a leader on global child poverty reduction under previous Labour governments, but has fallen behind on its responsibilities since 2010. The upcoming G20 Leaders’ Summit in Brazil is a key opportunity to take a leading role in ensuring that the G20 lives up to its promises to the youngest children around the world.
Decay Modes of Unstable Strings in Plane-Wave String Field Theory

description: The cubic interaction vertex of light-cone string field theory in the plane-wave background has a simple effective form when considering states with only bosonic excitations. This simple effective interaction vertex is used in this paper to calculate the three string interaction matrix elements for states of arbitrary bosonic excitation and these results are used to examine certain decay modes on the mass-shell. It is shown that the matrix elements of one string to two string decays involving only bosonic excitations will vanish to all orders in 1/mu on the mass-shell when the number of excitations on the initial string is less than or equal to two, but in general will not vanish when the number of excitations is greater than two. Also, a truncated calculation of the mass-shell matrix elements for one string to three string decays of two excitation states is performed and suggests that these matrix elements do not vanish on the mass-shell. There is, however, a quantitative discrepancy between this last result and its (also non-vanishing) gauge theory prediction from the BMN correspondence.

description: We discuss the ground state of a pyrochlore lattice of threefold-orbitally-degenerate $S=1/2$ magnetic ions. We derive an effective spin-orbital Hamiltonian and show that the orbital degrees of freedom can modulate the spin exchange, removing the infinite spin-degeneracy characteristic of pyrochlore structures. The resulting state is a collection of spin-singlet dimers, with a residual degeneracy due to their relative orientation. This latter is lifted by a magneto-elastic interaction, induced in the spin-singlet phase-space, that forces a tetragonal distortion. Such a theory provides an explanation for the helical spin-singlet pattern observed in the B-spinel MgTi$_2$O$_4$.
