Bevezetés a Központosítás és piaci reform című kötethez = Introduction to the volume Centralization and Market Reform

Az alábbi írás Kornai János életműsorozata közeljövőben megjelenő harmadik kötetének bevezetője alapján készült. (A sorozat első kötete, A hiány és második kötete, A szocialista rendszer 2012-ben jelent meg.) Ritkán fordul elő, hogy életművét rendszerezve, egy szerző maga veszi tételesen sorra írásait, tárja fel az írások megszületésének körülményeit, és elemzi őket több évtized távlatából. Kornai János életműsorozatának összeállításakor erre a rendkívüli feladatra vállalkozott. A kötetben megjelenő 22 íráshoz fűzött gondolatainak közlésekor mai szemmel veszi górcső alá az egy kivételével a rendszerváltás előtt írt cikkeit, valamint 1956-ban írott első könyvét, A túlzott központosítást. Az írásokat rendszerező bevezető a központosításra és a piaci reformra összpontosítja a figyelmet - e témakörről bebizonyosodott, hogy korai még csupán a közgazdaságtani elmélettörténet fejezeteként számon tartani. A kötetben megjelenő írások egy része közvetlenül kapcsolódik a magyar gazdaság tapasztalataihoz, másik része pedig elméleti jellegű. Ennek megfelelően az itt közölt bevezetés is foglalkozik mind a magyar gazdaságtörténet máig is figyelemre méltó és tanulságos gyakorlati problémáival, mind pedig a szocializmust és a kapitalizmust, a centralizált és decentralizált formákat összehasonlító általános elméletekkel. ______ This piece forms the introduction to the forthcoming third volume of János Kor-nai s life s work series reissued in Hungarian. (The first and second volumes, Economics of Shortage and The Political Economy of the Socialist System, ap-peared in 2012.) It is rare for an author to arrange his own life s work, taking his writings item by item, presenting the circumstances in which they arose, and ana-lysing them decades later. His thoughts on the twenty-two writings in the volume, at the time of republication, involve scrutinizing with present-day eyes articles written, with one exception, before the change of system, along with his first book, Overcentralization, written in 1956. The introduction that systematizes these fo-cuses on centralization and on market reform - events show it is still too soon to see these subjects simply as a chapter in the theoretical history of economics. Some of the articles draw directly on experiences with the Hungarian economy, while others have a theoretical nature. So the introduction also deals both with practical problems of Hungarian economic history that remain notable and instructive, and with comparative general theories of socialism and capitalism and centralized and decentralized forms.

What are the economic prospects of developing aquaculture in Queensland to supply the low price white fillet market? Lessons from the US channel catfish industry

The farming of channel catfish (Ictalurus punctatus) is the largest (by volume and value) and most successful (in terms of market impact) aquaculture industry in the United States of America. Farmed channel catfish is the most consumed (in terms of volume per capita) fish fillet in the U.S. market. Within Australia, it has long been suggested by researchers and industry that silver perch (Bidyanus bidyanus) and possibly other endemic teraponid species possess similar biological attributes for aquaculture as channel catfish and may have the potential to generate a similar industry. The current teraponid industry in Australia, however, shows very little resemblance to the catfish industry, either in production style or market philosophy. A well established budget framework from the literature on U.S. channel catfish farming has been adapted for cost and climate conditions of the Burdekin region, Queensland, Australia. Breakeven prices for the hypothetical teraponid farms were found to be up to 50% higher than those published for catfish farms however were much lower than those reported for silver perch production in Australia using current, endemic styles of production. The breakeven prices for the hypothetical teraponid farms were most sensitive (in order of significance) to feed prices, production rates, interest rates, fingerling prices and electricity prices. At equivalent feed costs the costs of production between the hypothetical catfish farms in the Mississippi, U.S. and the hypothetical teraponid farms in the Burdekin, Australia were remarkably similar. The cost of feeds suitable for teraponid production in Australia are currently around double that of catfish feeds in the U.S. Issues currently hindering the development of a large scale teraponid industry in Australia are discussed.

Listening to the Whispers of Matter Through Arabic Hermeticism: New Studies on the Book of the Treasure of Alexander

The Jabirian Corpus refers to the K. Thahirat Al-`Iskandar, ""The Book of the Treasure of Alexander"" (hereafter BTA), as one of several forgeries suggesting that alchemical secrets were hidden in inscriptions in various places. The book was neglected until 1926, when Julius Ruska discussed it in his work on the Emerald Tablet, placing the BTA within the literature related to the development of Arabic alchemy. His preliminary study became an essential reference and encouraged many scholars to work on the BTA in the following decades. Some years ago, we completed the first translation of the BTA into a Western language. The work was based on the acephalous Escorial manuscript, which we identified as a fourteenth-century copy of the BTA. This manuscript is peculiar, as part of it is encoded. After finishing our translation, we started to establish the text of the BTA. At present, the text is in process of fixation-to be followed by textual criticism-and has been the main focus of a thorough study of ours on medieval hermeticism and alchemy. A sample of the work currently in progress is presented in this paper: an analysis of the variations between different manuscripts along with a study and English translation of its alchemical chapter.

Earnings management and economic crises in the brazilian capital market

The 2008 economic crisis challenged accounting, either demanding recognition and measurement criteria well adjusted to this scenario or even questioning its ability to inform appropriately entities' financial situation before the crisis occurred. So, our purpose was to verify if during economic crises listed companies in the Brazilian capital market tended to adopt earnings management (EM) practices. Our sample consisted in 3,772 firm-years observations, in 13 years - 1997 to 2009. We developed regression models considering discretionary accruals as EM proxy (dependent variable), crisis as a macroeconomic factor (dummy variable of interest), ROA, market-to-book, size, leverage, foreign direct investment (FDI) and sector as control variables. Different for previous EM studies two approaches were used in data panel regression models and multiple crises were observed simultaneously. Statistics tests revealed a significant relation between economic crisis and EM practices concerning listed companies in Brazil in both approaches used.
