The authors approach this situation by studying the Hermite–Hadamard inequality, establishing a useful identity using Raina’s fractional integral operator in the setting of ϕ -convex functions, obtaining some integral inequalities connected with the right-hand side of Hermite–Hadamard-type inequalities for Raina’s fractional integrals. Various special cases have been identified
Effect of magnetization pinning on the spectrum of spin waves in magnonic antidot waveguides
No full textWe study the spin-wave spectra in magnonic antidot waveguides (MAWs) for two limiting cases (strong and negligible) of the surface anisotropy at the ferromagnet/air interface. The MAWs under investigation have the form of a thin stripe of permalloy with a single row of periodically arranged antidots in the middle. The introduction of a magnetization pinning at the edges of the permalloy stripe and the edges of antidots is found to modify the spin-wave spectrum. This effect is shown to be necessary for magnonic gaps to open in the considered systems. Our study demonstrates that the surface anisotropy can be crucial in the practical applications of MAWs and related structures and in the interpretation of experimental results in one- and two-dimensional magnonic crystals. We used three different numerical methods, i.e., plane waves method (PWM), finite difference method, and finite element method to validate the results. We showed that PWM in the present formulation assumes pinned magnetization, while in micromagnetic simulations special care must be taken to introduce pinning

Developing countries'participation in the World Trade Organization
No full textIn the 1960s and 1970s developing countries viewed UNCTAD (United Nations Conference on Trade&Development) rather than the GATT (General Agreement on Tariffs&Trade) as the main institution through which to promote their interests in international trade. But beginning with the Uruguay Round in the mid-1980s, their attitude changed, many more of them became members of the GATT, and a significant number played an active role in negotiations. The author analyzes developing countries'representation and participation in the World Trade Organization (WTO) as of mid-1997 to determine how developing countries can effectively promote their interests and discharge their responsibilities under the rules and agreements of the new organization. He concludes that although many developing countries are actively participating in the new process, more than half of the developing countries that are members of the WTO participate little more than they did in the early 1980s and have not increased their staffing, despite the vastly greater complexity of issues and obligations. Institutional weaknesses at home are the main constraints to effective participation and representation of their interests at the WTO. To make their participation more effective, he recommends that the developing countries establish adequately staffed WTO missions based in Geneva; failing that, pooling their resources and representation in Geneva; and being sure to pay their dues, which are typically small. He also recommends that the international community place higher priority on programs of assistance in support of institutional development of poorer countries aimed at enhancing their capacity to participate in the international trading system and the WTO -- and that the WTO review its internal rules and procedures to ensure that inadvertently they do not make developing countries participation more difficult.Economic Theory&Research,Decentralization,Economic Conditions and Volatility,Country Strategy&Performance,Labor&Employment Law,Trade and Services,Poverty Assessment,Economic Theory&Research,World Trade Organization,Country Strategy&Performance
"Donde se descomponen las colas de los burros" de Carolina Vivas. La Antígona latinoamericana del siglo XXI: no es el dolor de una, es el dolor de todas.
No full textIn this article we will analyze the play Donde se descomponen las colas de los burros by the playwright Carolina Vivas, which can be read as a reception of the tragedy Antigone. In this sense, we are interested in presenting the transformation of the character and the argument in the Latin American context, to visualize how the previous appropriation of the classic text in the continent influences the work of the Colombian author and, at the same time, to highlight the elements of the tragedy that the author rescues and modifies. Also, we will present a trend of the various readings and receptions of Antigone, emphasizing those carried out in Latin America. We will analyze this elements to situate the place from where the rewriting of Carolina Vivas is located and presented as a piece that, due to the way in which it rewrites the plot and the figure of Antigone, is configured as a milestone in the already extensive tradition of receptions of the Sophoclean tragedy in our continent.En el presente artículo analizaremos la obra Donde se descomponen las colas de los burros de la dramaturga Carolina Vivas, la que puede ser leída como una recepción de la tragedia Antígona. En este sentido, nos interesa presentar la transformación del personaje y su argumento en el contexto latinoamericano, para visualizar cómo la apropiación previa del texto clásico en el continente influye en la obra de la autora colombiana y, a su vez, para destacar los elementos de la tragedia que ella rescata y modifica. Para esto presentaremos un recorrido por diversas las lecturas y recepciones de Antígona, enfatizando las realizadas en Latinoamérica. Estudiaremos todo lo anterior para circunscribir el lugar desde donde se sitúa la reescritura de Carolina Vivas y pensarla como una pieza que, debido a la particular forma en que reescribe el argumento y la figura de Antígona, se configura como un hito en la ya extensa tradición de recepciones de la tragedia de Sófocles en nuestro continente
What macroeconomic policies are"sound?"
No full textMost people agree that the soundness of macroeconomic policies should be judged by their efficacy in meeting the objectives of steady growth, full employment, stable prices, and a viable external payments situation. What people debate about are the links between macroeconomics and economic structure--and in the current environment, the openness to foreign capital flows. As developing countries become more integrated into international financial markets, volatility may become an increasing fact of life. Faced with such volatility, how should these countries frame their macroeconomic policies? What broad principles should guide their macroeconomic management? In many developing countries, the openness of the capital account has been significant. Many countries have made the transition toward an open-economic paradigm. As a result, fluctuations in international capital and currency markets, as well as shifts in foreign investors'attitudes and confidence, have greatly affected local stock market prices, the level of foreign exchange reserves, and the scope for monetary and interest rate policy. Capital controls and foreign exchange restrictions have been significantly dismantled in a number of developing and transition economies. In 1970, only 34 countries--or 30 percent of the International Monetary Fund's membership-had assumed Article VIII of the IMF Articles of Agreement, declaring their currency convertible on current account transactions. By 1997, this figure had increased to 77 percent. Does financial integration make it more difficult to achieve macroeconomic stability? Apparently not, on the whole, although at times large short-term capital flows can lead to misaligned asset prices, including exchange rates. What financial integration does do is limit how far countries can pursue policies incompatible with medium-term financial stability. The disciplining effect of global financial and product markets applies not only to policymakers-through pressures on financial markets-but also to the private sector. Rather than constrain the pursuit of appropriate policies, globalization may add leverage and flexibility to such policies, easing financing constraints and extending the time during which countries can make adjustments. But markets will provide this leeway only if they perceive that countries are undertaking adjustments that address fundamental choices.Economic Theory&Research,Fiscal&Monetary Policy,Payment Systems&Infrastructure,Banks&Banking Reform,Environmental Economics&Policies,Banks&Banking Reform,Environmental Economics&Policies,Financial Intermediation,Economic Theory&Research,Macroeconomic Management
Voucher privatization with investment funds : an institutional analysis
No full textCommon wisdom among post-socialist reformers has beento use voucher investment funds to provide the corporate governance needed to restructure newly privatized enterprises after mass privatization efforts. The idea has been that mass privatization would spread the ownership too wide and make corporate governance difficult. The author examines the likely institutional behavior of voucher funds and the possible effects of their development on a transition economy. Since most policy advice has been in favor of voucher privatization with investment funds, the author can be seen as playing the devil's advocate, but his argument is institutional, not statistical. Policymaking requires insight and foresight into how institutions will tend to function. He concludes that voucher funds will introduce a bias in the economy away from the real industrial sector toward an ersatz"financial sector"that will have little if any positive financial role but will be well-protected by friendly regulators. One long-term consequence of voucher privatization with investment funds, according to this view, is a de facto"industrial policy"of real sector decapitalization in favor of short-term rent-seeking by fund managers through board sinecures and lucrative side deals with portfolio companies and through financial market manipulation and paper entrepreneurship in the"financial sector."Without strong corporate governance from the funds and without stable ownership of their own, many enterprise managers will exploit the post-socialist version of the"separation of ownership and control"to grab what they can in the form of salaries, bonuses, perquisites, and side deals. The most likely results of the strategy of voucher privatization with investment funds may be a two-sided grab fest by fund managers and enterprise managers -- together with the accompanying drift, stagnation, and decapitalization of the privatized industrial sector.Economic Adjustment and Lending,Payment Systems&Infrastructure,International Terrorism&Counterterrorism,Economic Theory&Research,Banks&Banking Reform,International Terrorism&Counterterrorism,Banks&Banking Reform,Economic Adjustment and Lending,Environmental Economics&Policies,Economic Theory&Research
Las virtudes, fuerzas vivas del alma en Hildegarda de Bingen
No full textPese al papel preponderante que el tema de las virtudes juega en la obra de Hildegarda de Bingen, éste no ha sido aún suficientemente analizado en relación con su concepción del ser humano como centro de la creación y del universo. Haciéndose eco de la caracterización de las virtudes en el contexto monástico benedictino y cisterciense, la autora desarrolla una analogía entre las virtudes que orientan al alma humana hacia la salvación y las fuerzas vivas que dinamizan el universo. El análisis interpretativo de pasajes destacados de su corpus pone de manifiesto una reflexión innovadora en torno a las virtudes como fuerzas morales de dimensión cósmica, mediadoras de una “renouatio” en el alma.Despite the main role which the subject of the virtues plays in Hildegard of Bingen’s work, it has not yet been sufficiently analysed in relation to her conception of the human being as the centre of the creation and the universe. Echoing the characterization of the virtues in the context of Benedictine and Cistercian monasticism, the author develops an analogy between the virtues which direct the human soul along the road toward salvation and the living forces which move the universe. An interpretative analysis of some outstanding passages of her corpus shows a innovative reflection on the virtues both as moral and cosmic forces, mediators of a “renouatio” in the soul
