Reconciling money and goods: Keynes's commodity and currency plans for the postwar world
No full textGrowing volatility of commodity prices has been both symptom and factor of instability over the past years. The problem, however, is not new. In the interwar period, it already attracted the attention of Keynes, who ascribed it to the lack of storage of surplus stocks. According to Keynes, markets for raw materials and foodstuffs are inherently unstable. Compared with other forms of wealth, particularly financial assets, commodities are unattractive for private agents since they not only yield nothing but entail high carrying costs. In order to supplement inadequate private storage and to provide a buffer between production and supply and between consumption and demand, Keynes proposed to arrange public storage of commodities in buffer stocks under the management of an international organization. Between 1942 and 1944, his plans for a Commodity Control were widely discussed and repeatedly redrafted, but, like the Clearing Union proposal, they were eventually set aside. This research analyses the peculiar institutional design of Keynes’s postwar commodity schemes
La metodología de las 5 S y su comunicación estratégica
No full textEn la actualidad, uno de los principales factores que permiten subsistir a las organizaciones es
que éstas sean competitivas. Para ello las empresas requieren experimentar un mejoramiento
continuo de sus prácticas, tarea que se debe basar en la colaboración de todas las personas que
constituyen la organización. En el presente trabajo se integran las bases teóricas, prácticas y
resultados de un proyecto de calidad, utilizando la metodología de las 5S´s el cual es un sistema
enfocado en la mejora continua, donde su naturaleza es la la obtención de objetivos a corto y
mediano plazo dentro de una organización, empresa y/o institución. Dicha metodología es dada a
conocer a través de la comunicación; de ahí la necesidad de abordar el estudio desde el plano de la
comunicación estratégica, en conexión con las relaciones institucionales como herramienta
integradora, dándole así un carácter sumatorio a las cinco etapas de las 5S´s : Seiri, Seiton, Seiso,
Seiketsu y Shitsuke, dentro de la empresa de Cervecería y Maltería Quilmes. El estudio muestra las
características generales de la organización de referencia; un análisis del macro y micro entorno de
la institución; se describen la cultura organizacional, los valores, actitudes, la motivación y el
cambio del individuo dentro de la organización; así como la comunicación estratégica, los
diferentes públicos, el sistema de las 5S´s como herramienta de cambio y su análisis F.O.D.A, que
servirán de base para aplicar los beneficios de dicha metodología en cualquier organización y
demostrar que con pequeñas acciones y una correcta comunicación, se puede modificar la calidad
laboral, con respecto a las tareas, al ambiente o al aspecto económico de cada organización de
acuerdo a sus necesidades y objetivos.Fil: Fantacci, Daniela Elian
Complementary currencies
No full textRecent decades have witnessed the proliferation of monetary instruments that differ, in many respects, from the official currency issued by the central bank and by the regulated banking system, such as local currencies, corporate barter, and mutual credit systems. Today, complementary currencies tend to appear as a bizarre exception to the rule of one single, all-purpose currency for each country (or currency area). However, in historical and comparative perspective, it is monetary plurality that prevails: different monies coexist side by side, serving different purposes, in most economies throughout most periods. The most significant and pervasive distinction in premodern economies was between internal and external money: one currency for the domestic economy and a different one for foreign trade. Only the rise of modern territorial states in the seventeenth century established the uniformity of the currency in each jurisdiction and the monopoly of coinage as a prerogative of sovereignty. In this chapter, we provide a broad overview of the various forms of complementary currencies throughout history, we analyze more recent experiments, and we review current proposals to introduce parallel currencies, before we turn to discuss how an enquiry into monetary complementarity can help shed light on the very nature of money itself

Stabilization through p-dimethylaminobenzaldehyde of a new NLO-active phase of [E-4-(4-dimethylaminostyryl)-1-methylpyridinium] iodide: synthesis, structural characterization and theoretical investigation of its electronic properties
No full textCo-crystallization of p-N(CH3)2C6H4CHO and E-4-(4-dimethylaminostyryl)-1-methylpyridinium iodide ([DAMS]I) gives a new solid state form (A), characterized by high non-linear-optical (NLO) activity and quite different from the well known [DAMS]I salt (centrosymmetric and therefore inactive). The X-ray structural characterization, although affected by the extended disorder of p-N(CH3)2C6H4CHO, addresses a new kind of aggregation for the [DAMS+] chromophore molecules. In fact, together with the often encountered J-type aggregation, an unprecedented "fishbone" coupling is observed. Calculations using time-dependent density functional theory (TDDFT) prove that the absence of a J-aggregation band in the electronic absorption spectrum is due to the additional intermolecular interaction that quenches the expected J-type signal. Correlation between supramolecular arrangements of the chromophores and NLO properties is also discussed. © 2010 The Royal Society of Chemistry

Teaching International Monetary Economics. Two different views
No full textThis paper presents a critical analysis of the way in which international monetary economics is normally taught. The objective of this paper is twofold. On the one hand, we show how the most popular international economics manuals deal with exchange rate theory and its link with balance of payments equilibrium. In particular, we stress how the models proposed in these manuals cannot explain one of the biggest macroeconomic problems of our time, that of the imbalances of the balance of payments. On the other hand, we put forward an alternative Keynesian model. Assuming neither full employment nor balanced trade over the short or long run, the paper is intended as a new contribution to the post-Keynesian analysis of exchange rate theory. Finally, our model gives an original insight into the relationship between Liquidity Trap and structural economic imbalances in modern economies. ; international monetary economics, exchange rate determination, endogenous money, global imbalances, post-Keynesian economic
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Design of Ru(II) sensitizers endowed by three anchoring units for adsorption mode and light harvesting optimization
No full textWe report the design, synthesis and computational investigation of a class of Ru(II)-dyes based on mixed bipyridine ligands for use in dye-sensitized solar cells. These dyes are designed to preserve the optimal anchoring mode of the prototypical N719 sensitizer by three carboxylic groups, yet allowing for tunable optimization of their electronic and optical properties by selective substitution at one of the 4-4′ positions of a single bipyridine ligand with π-excessive heteroaromatic groups. We used Density Functional Theory/Time Dependent Density Functional Theory calculations to analyze the electronic structure and optical properties of the dye and to investigate the dye adsorption mode on a TiO2 nanoparticle model. Our results show that we are effectively able to introduce three carboxylic anchoring units into the dye and achieve at the same time an enhanced dye light harvesting, demonstrating the design concept. As a drawback of this type of dyes, the synthesis leads to a mixture of dye isomers, which are rather tedious to separate
QoS provisioning in GEO satellite with onboard processing using predictor algorithms
No full textRecently, IP satellite networks have attracted considerable interest as a technology to deliver high-bandwidth IP-based multimedia services to nationwide areas. In particular, IP satellite networks seem to be one of the most promising technologies for connecting users in rural areas, where a wired high-speed network (e.g., xDSL) is not foreseen to be used. However, one of the main problems arising here is to guarantee specific quality of service constraints in order to have good performance for each traffic class. Among various QoS approaches used in the Internet, recently the DiffServ technique has become the most promising solution, mainly for its scalability with respect to the IntServ approach. Moreover, in satellite communication systems, DiffServ computational capabilities are placed at the edge points, reducing the implementation complexity of the satellite onboard equipment. This article deals with the problem of QoS provisioning for packet traffic by considering some resource allocation schemes, including bandwidth allocation techniques and priority-driven onboard switching algorithms. As to the first aim, the proposed technique takes advantage of proper statistical traffic modeling to predict future bandwidth requests. This approach takes into consideration DiffServ-based traffic management to guarantee QoS priority among different users. Moreover, the satellite onboard switching problem has been addressed by considering a suitable implementation of the DiffServ policy based on a cellular neural network
