description: Nell’articolo l’autore espone la tesi che si ala moneta, poiché ha un’utilità propria, è da considerarsi un bene come tutti gli altri, legato agli altri beni da vincoli di complementarietà e sostituibilità, oggetto delle scelte dei consumatori in uno con gli altri beni. La dicotomia non esiste nelle menti degli individui e non può pertanto esistere nei mercati. La complementarietà, vincolo generale tra utilità di tutti i beni, esiste anche per il bene moneta e cò basta ad annullare la dicotomia

Masterarbeit

description: Die Arbeit einer Logopädin und die Arbeit einer Schulischen Heilpädagogin sind herausfordernd und anspruchsvoll. Und wenn sich die Berufsaufträge der beiden Berufsgruppen auch noch überschneiden, wird es richtiggehend spannend. Diese Masterarbeit befasst sich mit den Aufgaben und den Schnittmengen der Logopädie und der Schulischen Heilpädagogik. Sie deckt Zusammenhänge auf und legt Voraussetzungen dar, die als Bedingung für eine gelingende Integration eines Kindes in die Klasse gelten. Als Grundlage dienen einerseits ein Gruppeninterview, welches mit Vertreterinnen beider Berufsgruppen durchgeführt wurde, andererseits die Berufsaufträge der jeweiligen Berufsgruppe, basierend auf den Positionspapieren des Deutschschweizer Logopädinnen- und Logopädenverbandes, sowie der Broschüren der Hochschule für Heilpädagogik in Zürich. Es wird nach Aussagen zur subjektiven Sichtweise des eigenen Berufsauftrages, zu Schnittmengen mit dem Auftrag der jeweils anderen Berufsgruppe, sowie nach Formen gelebter Zusammenarbeit gesucht. Ergänzt werden diese Erkenntnisse aus der Praxis mit den Erkenntnissen der Theorie und münden schliesslich in einen Massnahmenplan, welcher darüber Auskunft gibt, wie vorgegangen werden kann, wenn sowohl die Logopädin als auch die Schulische Heilpädagogin mit einem Kind mit einer Lese-Rechtschreibschwierigkeit arbeiten.

description: Diy matter (DM) yield, in vitro organic matter digestibility (IVOMD) and contents of protein (CP) and fibre (NDF) of King grass (Pennisetum purpureum κ P. typhoides) were evaluated in two ecozoncs in centra] Jamaica - mid Clarendon/Manchester (in CM) and southern Manchester/St. Elizabeth (sME) - in order to determine its suitability as fodder crop for goal production. The parameters were determined on 6-wk (mCM$ and sMEg) or 9-wk (sMEj) regrowih in a randomized block design with four replicates, and treatment means tested as designed orthogonal contrasts: mCMs ν sME6, sMEg and sMEß ν sMEj. Goat manure was applied at the rate of 10-25 l/ha/yr. CP% (mCMs =16.5; sMEe = 11.3; sME, = 10.8), IVOMD% (61,5; 54.8; 56.2), and yield (t/ha/yr) of DM (30,2; 2.4; 14.3), CP (4,90; 0.27; 1.72) and DOM (18.5; 1.3; 8.1) were all significanUy lower (P<0.05) and NDP/0 (64.4; 68.6; 67.8) significantly higher (P<0.05) for soudiern Manchcsler/St, Elizabeth compared with mid Clarendon/Manchester. Harvesting at 9-wk compared with 6-wk interval in southern Manchester/St Elizabeth appeared to improve the yield components, but the differences were not significant (P>0.05). Nutrient contents were also similar for the two liarvcsting intervals. It was concluded that under rainfed conditions and low input regime King grass should not be recommended for southern Manchester/St Elizabeth.
title: Mate choice and reproductive success in the speckled bushcricket, Leptophyes punctatissima
Creators: name: Kilduff, Ian Andrew
Publisher: name: The Open University
Year: 2000

description: Leptophyes punctatissima is unusual in that both sexes call. The male calls, the female replies and the male performs phonotaxis to the stationary female. Consequently mate choice could occur at either of two stages: first, during the interchange of calls and second, on the basis of proximate criteria once the male has approached. There is no evidence that females choose their mates on the basis of calling behaviour or call characteristics, though males that call more may achieve more matings. There is no evidence that body asymmetry has any effect on mating success for either sex. Males on a protein-supplemented diet do not produce larger spermatophores than males whose diet is not supplemented, but they do mate more often, possibly as a result of female choice but more likely because diet affects the rate at which males can produce spermatophores. Unsupplemented females mate more often than supplemented females, possibly as a result of male male choice or because they are seeking matings so that they can supplement their diet with spermatophores. Males give larger spermatophores to unsupplemented females. Larger males produce larger spermatophores. They also mate more often than smaller males, possibly as a consequence of female choice, success in male-male contests, or because larger males have larger energy reserves and can produce spermatophores more quickly. Larger females mate more often than smaller females but only when their diet was supplemented. Females lay more eggs the more times they mate. Females lay heavier eggs after their first mating than they do in later batches, and unsupplemented females lay more eggs after their first mating than supplemented females do, but otherwise female size, diet or level of asymmetry has no effect on the size or weight of eggs, or the number of eggs laid. The total weight of spermatophores females receive does not affect any measure of female reproductive success: neither fecundity, egg size or egg weight is affected by the weight of spermatophores females consume, irrespective of the diet the females were maintained on. Diet, size or number of matings does not affect female longevity.

description: The light singlino-like neutralino is expected to be a promising candidate for DM in the allowed parameter space of the NMSSM. The DM annihilation process takes place via the light Higgs bosons which are natural in this model. Identifying the allowed region of parameter space including various constraints, the detection prospect of such light DM candidate and Higgs bosons are explored at the LHC with its high luminosity options. Light Higgs bosons and the DM candidate, the lightest singlino-like neutralino are indirectly produced at the LHC via the SM Higgs production and its subsequent decays. Jet substructure techniques are used to tag boosted Higgs. It is found that the favourable range of masses of Higgs bosons and neutralino, compatible with a low mass DM solution, can be discovered with a reasonable signal significance ($\sim 5 σ$) at the LHC, with the center of mass energy $\sqrt{s}=14$ TeV and integrated luminosity options $\rm{\cal L}=300~fb^{-1}$ and 3000 $\rm fb^{-1}$.

description: Magnetic excitation spectra c"(q,w) of YBa2Cu3Oy and La214 systems have been studied. For La1.88Sr0.12CuO4, c"(q,w) have been measured up to ~30 meV and existing data have been analyzed up to the energy w~150 meV by using the phenomenological expression of the generalized magnetic susceptibility c(q,w)=c0(q,w)/{1+J(q)c0(q,w)}, where c0(q,w) is the susceptibility of the electrons without the exchange coupling J(q) among them. In the relatively low energy region up to slightly above the resonance energy Er, it has been reported by the authors' group that the expression can explain characteristics of the q- and w-dependence of the spectra of YBa2Cu3Oy (YBCO or YBCOy). Here, it is also pointed out that the expression can reproduce the rotation of four incommensurate peaks of c"(q,w) within the a*-b* plane about (p/a, p/a) {or so-called (p, p)} point by 45 degree, which occurs as w goes to the energy region far above Er from E below Er. For La2-xSrxCuO4 and La2-xBaxCuO4, agreements between the observed results and the calculations are less satisfactory than for YBCO, indicating that we have to take account of the existence of the "stripes" to consistently explain the observed c"(q,w) of La214 system especially near x=1/8.

description: Using material flow analysis (MFA) and exergy analysis, two competing scenarios for the management of municipal plastic waste arising from private households are evaluated. In Scenario A there is no source-separation of plastics, and the mixed waste stream is sent for incineration to a waste-to-energy plant (energy recovery). In Scenario B plastics are source-separated and sent to a material recycling facility (MRF) for the production of recyclates that substitute virgin plastics from primary sources (material recovery). The -systems expansion- approach is applied to make the basket of products (electricity, heat, plastics) in Scenario A comparable to that in Scenario B. This step depends on the substitution factor alpha (-), defined as the ratio of quantity of primary plastic that can be replaced to the amount of recyclate needed to substitute it to achieve equivalent performance, of the recyclates. The total cumulative exergy demand (CExD) of the expanded systems are computed. It is found that for alpha (-) > 0.16 natural resource depletion in Scenario B is less than that in Scenario A, as measured by the CExD indicator and material recycling of the plastic fraction is favored. When alpha (-) < 0.16, Scenario A, incineration of the plastic fraction, is exergetically favored.

description: Sustainable, tropical forage-livestock production systems must be based on maintenance of pasture botanical composition. Sheep were allowed to graze rotationally (14 d graze, 28 d rest) on a guinea grass (Panicum maximum) pasture at four levels of hcrbage-on-ofier (HO) of 4, 7, 10, and 13% dry matter of animal body weight (BW). Rotational grazing was continued for three years and HO was regressed on forage and animal data to determine carrying capacity of the pasture, Mean, yearly stocking rate declined linearly from 775 to 540 kg BW ha'1 d"1 in response to increasing HO. Grass canopy heights for the pre-graze (0,35-0,65 m) and post-graze (0,20-0.45 m) pasture increased in a curvilinear pattern with HO. In both eases, the greatest increase in height occurred between the 4% and 7% HO, followed by marginal increments as HO was increased further. Pre-graze herbage mass increased linearly from 1.0 to 2,5 Mg ha"1 and post-graze herbage mass increased curvilinearly from 0.7 to 2.0 Mg ha'1 as HO was increased. The guinea grass frequency of occurrence on pasture prior to initiation of grazing was approximately 95%. Frequency remained unchanged during tlte first year of grazing but declined to 75% following three years of rotational grazing at the 4% HO compared to 85-95% at the remaining HO. The frequency of broad leaf weed occurrence which was 17%, initially, remained constant under 13% HO treatment but increased linearly to approximately 100% as HO was reduced to 4%. Sheep average daily gain ranged between 0.071 and 0,076 kg independently of HO, whereas, due to major differences in stocking rates, yearly livewcight gain increased from 630 kg ha"1 with 13%, HO to 815 kg lia'1 with 4% HO treatments. These results indicate a direct link between high, short-term animal production potential at high stocking rates and rapid guinea grass pasture deterioration to undesirable plant associations. Our estimate of tlie optimum stocking rate under a rotational grazing management system for St, Croix ranged from 575 to 690 kg BW ha"1 da"\ depending on tlie seasonal rainfall (1000-1200 mm).

description: To respect physics and nature, cellular automata (CA) models of self-organisation, emergence, computation and logical universality should be isotropic, having equivalent dynamics in all directions. We present a novel paradigm, the iso-rule, a concise expression for isotropic CA by the output table for each isotropic neighborhood group, allowing an efficient method of navigating and exploring iso-rule-space. We describe new functions and tools in DDLab to generate iso-groups and iso-rules, for multi-value as well as binary, in one, two and three dimensions. These methods include filing, filtering, mutating, analysing dynamics by input-frequency and entropy, identifying the critical iso-groups for glider-gun/eater dynamics, and automatically classifying iso-rule-space. We illustrate these ideas and methods for two dimensional CA on square and hexagonal lattices.

Cognitive processes related to reading and arithmetic
Creators: name: Tang, Winnie
Publisher: name: University of British Columbia
Year: 2011

description: This study explored the robustness of the low achievement approach for diagnosing learning difficulties in a group of one hundred and twenty-one grade 3 children in two inner city schools. The children were tested using standardized tests of achievement and experimental cognitive measures. The cognitive profiles of the low achievers, the children with difficulties in reading and/or arithmetic, were examined and the results showed that the defining feature in these low achievers was a phonological deficit. The Chi square tests in this study contributed to providing important information that was particularly useful for individual diagnosis. The pattern of association between low reading achievement and the measures tapping into phonological processing showed that there was little or no likelihood of being normally achieving in reading when the phonological processing skills were low. Three different cutoff points for low achievement were used reflecting differing levels of stringency. Children in the low groups, regardless of the cutoff points used, exhibited similar characteristics in terms of their cognitive deficits. Hierarchical regression analyses of the predictor variables related to reading and arithmetic revealed that phonological processing contributed to accounting for large proportions of unique variance in both reading and arithmetic. The findings in this study suggests that the phonological core deficit model for understanding reading difficulties is robust even in a population where there are confounding social variables associated with the children (e.g., low SES and ESL home background). As well, phonological processing also emerged as being important in contributing to children's achievement in arithmetic. The efficacy of the low achievement approach was affirmed in this study: children with cognitive processing deficits related to reading or arithmetic were identified using a low cutoff of somewhere around or below the 25th percentile in standardized achievement tests. Furthermore, using the low achievement approach had the benefit of avoiding biases previously identified in IQ-achievement discrepancy definitions of learning disability.

The present paper discusses a number of recent developments, and argues that these have created a gold exchange standard which in many ways functions differently than the older one. After analysing the changes that have taken place in the international monetary system, the author reviews some proposals - namely the Roosa Plan and the Maudling Plan - which would further modify traditional operations under the gold exchange standard. Such proposals are compared with the present and possible future role of the International Monetary Fund. JEL: E42, F33

description: Water molecules and molecular chaperones efficiently help the protein folding process. Here we describe their action in the context of the energy and topological networks of proteins. In energy terms water and chaperones were suggested to decrease the activation energy between various local energy minima smoothing the energy landscape, rescuing misfolded proteins from conformational traps and stabilizing their native structure. In kinetic terms water and chaperones may make the punctuated equilibrium of conformational changes less punctuated and help protein relaxation. Finally, water and chaperones may help the convergence of multiple energy landscapes during protein-macromolecule interactions. We also discuss the possibility of the introduction of protein games to narrow the multitude of the energy landscapes when a protein binds to another macromolecule. Both water and chaperones provide a diffuse set of rapidly fluctuating weak links (low affinity and low probability interactions), which allow the generalization of all these statements to a multitude of networks.

Year: 1984

description: This thesis seeks to apply the methodology developed in Arthur Marwick's Class: Image and Reality in Britain, France and the U. S. A. Since 1930 to the study of the Czechoslovak First Republica It examines first those salient features in economic and political development which helped to shape Czech and Slovak societies in this period, paying particular attention to the impact of independence in 1918, and of subsequent social and economic reforms, on class relationships. It considers also the dichotomy between Czech democratic aspirations and the imperatives of the Habsburg past. Next it analyses contemporary perceptions of class, and of other dimensions of stratification, categorising these by source as follows: legal and bureaucratic materials, political party programmes, academic writings and informal and anecdotal accounts. A rough outline of those social groups which contemporaries felt to be of particular importance is gradually built up, and the interplay between the divisions and labels presented in the various sources is discussed. Then demonstrable facts of inecuality, such as the distribution of wealth and incomes, and the nature of housing, are outlined, and some general observations are made about the distribution of power and authority in inter-war Czechoslovakia, and about the relevance of voting behaviour as an indicator of the significance of class at this time. Finally the thesis reaches some overall conclusions about the nature and historical import of class in inter-war Czechoslovakia, with special reference to the notion of Czechoslovakia as the "society of the little man".

description: Increasing greenhouse gas concentration in the atmosphere and the resulting warming of the climate are a great challenge for humanity. Politics has several instruments at hand to tackle this issue, one of them being the trade in emission permits. Based on the economic theory of emission trading the paper examines trading systems in the EU, Australia and the US and possible barriers and challenges in linking them. In combination with the opinions and experiences expressed in nine interviews carried out with experts from different areas, private industry, universities and public administration, a number of conclusions could be drawn. These have to be seen in light of a few basic assumptions the reader is made aware of before the start of the main part. They are presented to underline the viability of the cap-and-trade policy vis-à-vis different views. In the end, it turned out that there are several issues which represent major obstacles to linking the systems analysed. Comparability on multiple levels emerged as the essential problem, but also minor deficiencies within the schemes as such proved to be issues of importance beforehand. As a conclusion, for a direct link to become effective in the future, these barriers would have to be removed by political coordination or even integration, which seems unrealistic at present, despite the economic and social similarities in the regions examined. However, an idea to initiate this process is presented at the end as well as an outlook on the issue of involving emerging and developing countries.

description: The increased consumption of new and exotic vegetables of tropical origin such as dasheen {Colocasia esculenta L. Schott.) and amaranth {Amaranthus spp,) has stimulated great interest for research on diese crops. Tropical and specialty green leaf vegetables are a major group of horticultural crops that have been the focus of attention in national symposia on new crops. The U.S. imported significant amounts of tropical green leaf vegetables during die past 5 to 8 years, and this trend will likely continue. Some of these crops can be grown in the U.S., but factors such as scarcity of seeds and planting materials coupled with inadequate information on cultural management practices limit the production of these crops in the U.S. The University of the Virgin tslands has initialed a research project lo collect and evaluate germplasm of tropical leaf vegetables with market potential. The approach of this project includes: 1) germplasm collection and evaluation; 2) development of sustainable crop management and cropping systems and 3) conservation and maintenance of germplasm materials. Preliminary field evaluation trial indicates that Malabar spinach (Basella spp.)', water spinach (Ipomoea aquatica Forsk,); potato greens {ipomoea batatas L„ Lam); and jute mallow {Carchorus olitorius L.) showed potential yields comparable to yields of common leaf vegetables such as collard (5. oleracea L,. Acephala); and mustard green {B. juncea L,, Czerniak). Multiple harvests from these crops during the growing season resulted in fresh edible yields ranging from 3.22 Id 52,0 g m"2 day'1.

description: Field experiments were conducted during the 1995 and 1996 seasons to evaluate the yield and water use of cucumber (Cucumis sativus L. cv, 'Calypso', 1995 and 'Dasher IT, 1996) grown with black plastic and grass straw mulch under 3 levels of drip irrigation. Cucumber was grown in replicated plots arranged in randomised complete block design and mulched with cither black plastic (L25 mil) or dry guinea grass (Panicum maximum L.) straw (5,0-6.5 cm thick). Plots were drip-irrigated at soil water tensions corresponding to 20,40, and 60 kPa. Number of marketable fruits, fruit size, total weight of fruits and marketable yield were recorded for each harvest In 1995, for all of the measures parameters, black plastic mulch resulted in significantly higher values than the straw mulch. Marketable yield (15.7 t ha"1) in plots with black plastic mulch was significantly higher (P<0.005) than plots with straw mulch (11.9 t ha'1). For both mulches, drip irrigation levels had no influence (P>0.10) on cucumbcr yield and yield components. Water use in straw-mulched plots was lower than plastic-mulched plots, but water use efficiency and economic returns to irrigation water were higher in plots with black plastic mulch. The incidence of fusarium wilt (Fusarium sp.) in plots with straw mulch was higher than plots with plastic mulch, a contributing factor for low yields in straw-mulched plots. In 1996, there were no significant differences observed between mulch treatments or irrigation regimes for any of the parameters measured. Production from the Dasher 11' cultivar was much higher than the yields obtained in 1995 from 'Calypso',

description: The shale gas revolution has become a ubiquitous presence in media and scientific circles, and has started to permeate political agendas across the globe. The hype spread from the US, where major technological advancements have rendered the exploitation of unconventional gas profitable and unleashed a virtually unbridled quest for the resource. The sudden increase of supply has caused gas prices to plummet and now provides the US industry and households with cheap energy and significant competitive leverage. After the diagnosis that the revolution had the potential to leave a lasting impact on global energy markets, not only carrying widespread economic, but also geopolitical implications, the question most naturally arose to what extent and under what conditions the US success could be replicated elsewhere. The aim of this paper is to provide a comprehensive analysis of the potential, challenges and limits of European shale gas. The potential has been heatedly debated and it is safe to say that uncertainty remains prevalent. Exact estimates continue to be scarce and the economic implications of the exploitation on the continent somewhat of a mystery. However, experts largely agree that considerable amounts of technically recoverable gas are trapped in European shale and could, despite more elevated costs due to geological constraints, higher wage-levels, less developed infrastructure and regulatory bottlenecks, go a long way to ensure security of supply, diversify energy sources and carry major welfare gains for European economies. Yet, the political debate remains highly divided and fluid. In large parts of Europe environmental qualms continue to dominate the headlines and nurture a lack of public acceptance, which appears to dampen political will and ultimately constrain the establishment of a shale gas industry. Shale gas would not solve all problems and surely has its drawbacks, but if used strategically, as a substitute for more carbon-intensive energy sources and a complement to renewables, the benefits seem to outweigh the costs and Europe would perhaps be well-advised to take a more pro-active approach towards the resource.

description: A study was conducted at the Fortuna Agricultural Substation to determine the effect of tree size-controlling roolstocks on yield of commercial mango cultivais Parvin and Tommy Atkins. These varieties were clcfl grafted on Eldon, Colombo Kidney, Mayagüczano/ Turpentine, Cubano, Malda, and Julie as rootstocks. Data on number and weight of fruits were collected during five consecutive crops starting two and three years after Tommy Atkins and Parvin trees, respectively, were planted in the orchard. Yield increased significandy during the first three crop years. Yield per tree was significantly higher for Parvin than for Tommy Atkins. Yields were higher for Parvin grafted on Julie and Malda and for Tommy Atkins grafted on Turpentine, Cubano and Julie. Yields were significantly lower on Eldon as rootstock irrespective of grafted variety.

description: Plusieurs entreprises se sont concentrées sur des préoccupations environnementales et sociales de leur chaîne logistique (SCM). Le Management Durable de la Supply Chain (MDSC) est une approche multifactorielle qui cherche à développer simultanément les performances environnementales, sociales et économiques à travers des pratiques de gestion. Cette approche cherche à améliorer des avantages durables aux différents intervenants des composantes de la SCM d’une entreprise en utilisant des pratiques stratégiques centrées sur la durabilité. Dans ce chapitre, nous allons essayer de synthétiser une analyse croisée de l'approche MDSC et son impact sur la durabilité. Ainsi, L’analyse théorique nous permet de présenter un cadre conceptuel qui expose les principaux facteurs de motivation, les obstacles et les différentes dimensions de la MDSC. En outre, l'impact sur la performance des pratiques MDSC est intégré. Le dernier point de ce chapitre évoquera un débat sur les participations théoriques et les apports de l'approche MDSC pour les praticiens.
title: The Rev. Francis Close and the Foundation of the Training Institution at Cheltenham 1845-78
Creators: name: Trafford, Robert Sydney

description: This study investigates the foundation and the first three decades of the teacher training institution at Cheltenham. Its main thesis is that the Cheltenham training college was primarily the work of one man, the Rev. Francis Close who was the incumbent of Cheltenham between 1824 - 1856. He played a key role at every stage including the ini tial period when the first proposal was made in 1845. Contrary to previous accounts it was not founded there in response to a widespread demand for a national institution based on evangelical principles. It was established as a result of Close's religious position within the Church of England, his dominant personality and the situation which he had helped to create in Cheltenham by that time. An evaluation of his career, his work in making Cheltenham a centre of education, his involvement in controversies and his educational ideas reveal him as a leading pioneer of education during the nineteenth century. His ideas on the training of teachers and the way he ensured that they were carried out are particularly important.

 The second part of the study includes research into the way the college was governed, an account of how it was financed, in particular how it was affected by the Revised Code, the staff, the students and their professional training. composition of the student body The chapter on the includes a detailed analysis of the first 288 students who were trained between 1847 and 1851 and of 2054 who were trained between 1852 and 1878. Throughout this period a very strong element of continuity in attitudes towards religious education and teacher training, which originated with Close, persisted against a background of rapid change.
From Hagedorn to Lee-Yang: Partition functions of $\mathcal{N}=4$ SYM theory at finite $N$

description: We study the thermodynamics of the maximally supersymmetric Yang-Mills theory with gauge group U(N) on R x S^3, dual to type IIB superstring theory on AdS_5 x S^5. While both theories are well-known to exhibit Hagedorn behavior at infinite N, we find evidence that this is replaced by Lee-Yang behavior at large but finite N: the zeros of the partition function condense into two arcs in the complex temperature plane that pinch the real axis at the temperature of the confinement-deconfinement transition. Concretely, we demonstrate this for the free theory via exact calculations of the (unrefined and refined) partition functions at N<=7 for the su(2) sector containing two complex scalars, as well as at N<=5 for the su(2|3) sector containing 3 complex scalars and 2 fermions. In order to obtain these explicit results, we use a Molien-Weyl formula for arbitrary field content, utilizing the equivalence of the partition function with what is known to mathematicians as the Poincare series of trace algebras of generic matrices. Via this Molien-Weyl formula, we also generate exact results for larger sectors.

description: We assume that the energy spectrum of a chaotic system undergoing symmetry breaking transitions can be represented as a superposition of independent level sequences, one increasing on the expense of the others. The relation between the fractional level densities of the sequences and the symmetry breaking interaction is deduced by comparing the asymptotic expression of the level-number variance with the corresponding expression obtained using the perturbation theory. This relation is supported by a comparison with previous numerical calculations. The predictions of the model for the nearest-neighbor-spacing distribution and the spectral rigidity are in agreement with the results of an acoustic resonance experiment.

description: Pigeon pea cultivars Kaki, 2B Bushy, PR 147 and Blanco, and Lines 12, 84, and 92 were evaluated at Juana Diaz, Puerto Rico. For their effect on weed suppression and pepper and tomato yield in the following cropping systems. Pigeon pea was grown from mid-July 1994 until 2 February 1995 when whole plant material above soil surface was mowed and disked into the soil. Pepper and tomato seedlings were transplanted after bedding 9 March 1995 and harvested during June 1995. Tlic seven cultivars reduced weed density, which ranged from 50 to 91% in the pepper management system. Value of produec obtained from the pigeon pea-pepper harvest was estimated at USSl9,945/ha, an increase of S9,865/ha over that of no pigeon pea rotation. In the tomato management system, weed suppression ranged from 69% to 89% with the same pigeon pea cultivais. Total value of produce from the pigeon pea-tomato harvest was estimated at $14,626/ha. Pigeon pea allelopadty contributed to weed suppression in both pepper and tomato management systems. Value of produce per unit area per year can be increased by the integration of pigeon pea in a rotation scheme with pepper and tomato.

description: The paper is an adapted and revised version of a memorandum that has served as a basis for discussion in several meeting of the Monetary Committee of the European Economic Community. It deals with the interplay of technical banking risks and general economic considerations concerning international foreign reserves. After having considered the temporary character of the recent US agreement proposals, it considers the composition of reserves as a long-term problem. The international monetary system is not the traditional one and although it might look formally unchanged, it is vastly changing everyday. According to the authors, pragmatic decisions on a consistent framework should not be based on security considerations from a banker’s point of view, but rather on considerations of a general economic character.

description: Monolayers of transition-metal dichalcogenides (TMDs) hold great promise as future nanoelectronic and optoelectronic devices. An essential feature for achieving high device performance is the use of suitable supporting substrates, which can affect the electronic and optical properties of these two-dimensional (2D) materials. Here, we perform many-body GW calculations using the SternheimerGW method to investigate the quasiparticle band structure of monolayer MoS2 subject to an effective dielectric screening model, which is meant to approximately describe substrate polarization in real device applications. We show that, within this model, the dielectric screening has a sizable effect on the quasiparticle band gap; for example, the gap renormalization is as large as 250 meV for MoS2 with model screening corresponding to SiO2. Within the G0W0 approximation, we also find that the inclusion of the effective screening induces a direct band gap, in contrast to the unscreened monolayer. We also find that the dielectric screening induces an enhancement of the carrier effective masses by as much as 27% for holes, shifts plasmon satellites, and redistributes quasiparticle weight. Our results highlight the importance of the dielectric environment in the design of 2D TMD-based devices.

Food Security and Poverty

description: The histoiy and economic damage caused by the white fly, Hemisia (abaci, is well documented worldwide. The processing tomato industry >n the Azua Valley of Ihc Dominican Republic, represents the main source of incomes for more than 3,000 small farmers and Uic principal activity For 4 tomato industries established in die region. The tomato industry was almost devastated as the result of (he presence of the White Fly and the geminivirus (TYLCV) infestations. To recover the productivity of the tomato crop, it was necessary to implement and validate a scries of integrated pest management practices. Correct planting time, use of resistant and early varieties, and application of legal measures, arc among these practices. Combined widi these, the production of tomato plantlets under mosquito net tunnels, reduces the early infection of TYLCV. This reduction results in an increase of yield and greater incomes to farmers. This paper describes a viable and economic method of producing planting materials using locally available resources.
