Gas chromatographic study of acetyl derivates of chlorinated guaiacols
1982
The gas chromatography of acetyl derivatives of guaiacol and all chlorinated guaiacols has been studied on SE-30, OV-351 and Carbowax 20M capillary columns. The retention order and relative retention times under isotermal and temperature-programmed conditions are discussed. Different retention times for all mono- and dichloro compounds have been observed on the SE-30 column. However, all trichloroguaiacol isomers were separated only on polar columns. The best overall temperature-programmed separations have been achieved on an SE-30 capillary column.
Asset Market Equilibria in Cryptocurrency Markets: Evidence from a Study of Privacy and Non-Privacy Coins
2019
This paper explores whether asset market equilibria in cryptocurrency markets exist. In doing so, it distinguishes between privacy and non-privacy coins. Most recently, privacy coins have attracted increasing attention in the public debate as non-privacy cryptocurrencies, such as Bitcoin, do not satisfy some users’ demands for anonymity. Analyzing ten cryptocurrencies with the highest market capitalization in each sub-market in the 2016–2018 period, we find that privacy coins and non-privacy coins exhibit two distinct market equilibria. Contributing to the current debate on the market efficiency of cryptocurrency markets, our findings provide evidence of market inefficiency. Moreover, the a…
Equity Issues in the Spanish Stock Market: Windows of Opportunity, Earnings Management or Market Timing?
2005
We investigate whether the market sentiment and/or the specific operating performance of firms that conducted an equity issue on the Spanish stock market during the period 1993-2000 are related to the long-run stock-return underperformance in the year following the issue of small and medium firms. Our results reveal that equity issues were conducted by large firms just when the market showed optimistic expectations towards large firms in general. This overoptimism towards large issue firms was related to the 1990s technology boom in the case of initial public offerings (IPO), but we detect earnings management by large firms that conducted a seasoned equity offering (SEO). In this context, s…
A Simulation Analysis of the Microstructure of an Order Driven Financial Market with Multiple Securities and Portfolio Choices
2005
In this paper we propose an artificial market where multiple risky assets are exchanged. Agents are constrained by the availability of resources and trade to adjust their portfolio according to an exogenously given target portfolio. We model the trading mechanism as a continuous auction order-driven market. Agents are heterogeneous in terms of desired target portfolio allocations, but they are homogeneous in terms of trading strategies. We investigate the role played by the trading mechanism in affecting the dynamics of prices, trading volume and volatility. We show that the institutional setting of a double auction market is sufficient to generate a non-normal distribution of price changes…
Sustainable urban transport policy in emerging countries – case study of Mexico
2015
Negatywne efekty zewnętrzne transportu stanowią bolączkę współczesnych miast, niekorzystnie oddziałując na procesy rozwoju społeczno-gospodarczego. Problemy te są widoczne nie tylko w krajach wysoko czy średnio rozwiniętych – w ogromnym stopniu borykają się z nimi wielomilionowe i wielkopowierzchniowe metropolie, które z kolei są charakterystyczne głównie dla krajów wschodzących, jak np. Chiny, Indie, Brazylia czy Meksyk. Celem artykułu jest przedstawienie wybranych aspektów polityki zrównoważonego rozwoju transportu w stolicy jednego z tych krajów – Meksyku. Autorka starała się również odpowiedzieć na pytanie, w jaki sposób specyficzne uwarunkowania lokalne o różnym charakterze determinują…
Fast enantiomeric separation of uniconazole and diniconazole by electrokinetic chromatography using an anionic cyclodextrin: application to the deter…
2000
The enantiomeric resolution of the fungicides uniconazole and diniconazole was performed using electrokinetic chromatography with cyclodextrins as pseudostationary phase (CD-EKC). A systematic evaluation of several chiral selectors was made. The anionic derivative carboxymethylated-gamma-cyclodextrin (CM-gamma-CD) was found to be the most appropriate for the enantioseparation of fungicides among all cyclodextrins tested. The influence of some experimental conditions such as nature and buffer pH, chiral selector concentration, and temperature on the enantiomeric separation of the compounds studied was also investigated. The use of a 50 mM phosphate buffer (pH 6.5) containing 5 mM CM-gamma-CD…

Il ruolo del Consiglio europeo nella Brexit
2019
Il Consiglio europeo ha svolto un ruolo di primo piano nella Brexit. L’articolo cerca di spiegare che questo ruolo è stato più ampio rispetto a quello espressamente conferito dall’art. 50 TUE per affrontare poi due problemi: nello svolgere questo ruolo il Consi- glio europeo ha agito solo come istituzione dell’Unione europea o anche come vertice di capi Stato? E ha rispettato il principio dell’equilibrio istituzionale? The European Council has been playing a leading role in Brexit procedure. This article aims at showing how this role does not simply reflect the powers explicitly assigned to the European Council under Article 50 TEU. Two more questions are addressed: In performing its role h…

Los «grupos financiero-industriales» en la Federación Rusa : Nuevas tendencias en el establecimiento de vínculos entre las esferas financiera y produ…
2000
El presente artículo tiene como objetivo estudiar las relaciones existentes entre las esferas financiera y productiva de la economía rusa. Para ello se analiza, en primer lugar, los aspectos legislativos de la formación de los grupos financiero-industriales, describiéndose los requisitos y las restricciones básicas para la formación de estos grupos. En segundo lugar, se revisa la distinta evolución desarrollada por los grupos financieroindustriales cuantificando el fenómeno, por un lado, así como su ubicación en el espacio ruso, por otro. En tercer lugar, se elabora una caracterización de los grupos financieros, enumerando los principales criterios de integración que se han detectado para l…
