Abstract: This work is the second of the series dedicated to the critical evaluation of the Chilopod specimens from the "Z. Matic" and " t. Negrea" collections - the only ones existing in Romania (vide "Literature cited"). The history of the study of Eupolybothrus tridentinus (Fanzago, 1874), the synonymies, the examined material, the redescription of the species based on specimens found in the two collections are presented. A nomenclatural updating of two old records is proposed: Eupolybothrus tridentinus (Fanzago) = Polybothrus leptopus sensu Matic, 1958; Eupolybothrus tridentinus (Fanzago) = Eupolybothrus leptopus f. brolemanni sensu Negrea, 1964. The paper concludes on some taxonomical and ecological remarks regarding the Eupolybothrus tridentinus (Fanzago) species.

Abstract: Z. Matic's collection, preserved at the Zoological Museum of the "Babe -Bolyai" University of Cluj-Napoca, and t. Negrea's collection, preserved at the "Emil Racovitza" Speleological Institute of Bucharest (the only chilopod collections existing in Romania) are containing three species of the Lithobius validus Meinert group: L. (L.) validus Meinert, 1872 (sensu Eason, 1974 a), L. (L.) moldavicus Prunesco, 1966 (sensu Negrea, in the present paper) and L. (L.) matici Prunesco, 1966. New synonymies are proposed: Lithobius punctulatus moldavicus Prunesco, 1966 = Lithobius moldavicus Negrea in this work = Lithobius validus Zapparoli, 1994 nov. syn.; Lithobius matici Prunesco, 1966 = Lithobius matici biharicus Prunesco, 1966 nov. syn. The subspecies Lithobius punctulatus moldavicus Prunesco, 1966 is elevated to the taxonomical rank of species, Lithobius moldavicus Prunesco, establishing its geographical area as it is currently known. The following species are redescribed: Lithobius validus Meinert, 1872, based on the Romanian Carpathians populations; Lithobius moldavicus Prunesco, 1966 based on the specimens of the Eastern Carpathians - including the type series, establishing a lectotypus and an allolectotypus; Lithobius matici Prunesco, 1966 based on populations from the Eastern Carpathians and the Western Carpathians.

Abstract: This is a modest contribution to the history of science, respectively the history of the Romanian biospeleology. Biospeleology, the science created by Emile Racovitza in 1907, knew, after the death of the scientist a second period of great development.This is the thriving period which began 5o years ago, in 1956, with the reorganization of the Institute of Speleology up to 2005, including the retirement of the last biospeleologists belonging to that generation – all more or less distinguished researchers, known as such outside Romania.The author, an eyewitness of these times, shows how, nine years after the death of Emile Racovitza, the Institute of Speleology – the first in the world – founded by the great biologist in 1920 within the framework of the Faculty of Science of the new ClujUniversity, was reorganized as an Institute of Speleology at a national level in two centers: a main one in Bucharest and a branch in Cluj. In the following we present the main achievements of the biospeleological teams from Bucharest and Cluj in the period between 1956 and 2005. In the end, we shortly analyse the development perspectives of the Romanian Biospeleology in the future.

Abstract: An important work of subterranean biology, signed by Francis Dov Por, Ophel: a groundwater biome based on chemoautotrophic resources. The global significance of the Ayyalon cave finds, Israel is presented and discussed in the present paper. The subject is a remarkable discovery suggesting the existence of a new aquatic subterranean biome autonomous energy based the author calls Ophel, the Hebrew word for “darkness” and “netherworld”). For F.D. Por, this biome links different marine chemosynthetic ecosystems in a global biospheric entity. Finally, F.D. POR hypothesizes on the existence of three overlapped biospheres: the bacteriosphere in the depths of the planet’s crust, which does not require light or oxygen; the aphotic, subterranean deuterobiosphere, formed of bacterial chemosynthesis based eukaryotes and limited-supplied dissolved oxygen from above-ground; the above-ground eubiosphere, based on aerobic photosynthesis. I would like to emphasize that, at my suggestion, Prof. Dr. F.D. Por participated at the 18th International Symposium of Biospeleology from Cluj-Napoca (Romania) at 10th to 15th July 2006 where he mentioned for the first time orally some data on the Ayyalon Cave and the Ophel biome.

Abstract: Rediscovery by the first author of three letters received by him from A. Nú ez Jiménez – at that time president of the Academy of Sciences of Cuba – throws new light on the events having lead to the organisation of the first biospeleological expedition to Cuba, this being at the same time the first scientific expedition abroad by Romanian naturalists.

Theoretical and Applied Economics , 2006,
Abstract: The development of academic training in Romania is a must for our country to adapt to the European Union professional standards. The article makes reference to the late evolution of English for Special Purposes (ESP) training in several universities in the country and to the case-study of ESP learning in the Academy of Economic Studies in Bucharest. English for Special Purposes is an academic subject based on the long-term professional and social needs of the specialised labor force in market economy. Its authentic content and learning/teaching tasks are selected and adapted to the curriculum subjects that the students attend to make their access autonomous to original professional sources.

Abstract: Situated on the border line between Romania and Hungary, Bihor a€“ Hajdu-Bihar counties are blessed with all natural types of terrain. There are mountains in the West, thermal water almost everywhere, caves and underground rivers that can be exploited for economic use. In this paper, the main subject focuses on developing the counties into an international tourist attraction, based on their natural resources. Being able to extract thermal water that is rich in numerous minerals that the human body can absorb, it can offer these counties an important competitive advantage. With age, comes a great deal of expenses in order to keep your body young. Having this natural resource, Bihor a€“ Hajdu-Bihar counties can project its goals on the development of future spas, which can attract tourists as well as investors. The methodology focuses first on identifying those areas that are rich in these thermal waters. Then, there will be presented a sketch of the ideal tourist profile for this type of activity. Then, based on the ideal tourist profile, there will be a selection of countries were these potential tourists live. If the county desires to adopt this plan, there will be extensive structural modifications on all economical and educational sectors in order to obtain maximum performances. The selection of future potential investors will be crucial for the future activities of the county. If the main objective will be the construction of spas, there will be an increase demand for qualified medical staff. This knowledge can be attained only in medical universities. The courses of a medical university can be followed only by those persons that have a bio-chemistry high school profile. If the investments will be made in this sector, the number of students of the medical university and of local high schools will have to increase exponentially. The tourists that will come will have to benefit from a treatment based on different products. The strategy should include attracting those investors that produce goods designed for body enrichment, and not to import these products from abroad. All these strategies that include investors, the education system, city halls, politicians and fiscal stimulus, can and will lead to a success story.

Abstract: Trade patterns across the globe vary in certain ways. For the EU27, the analyzed data suggests that approximately 70% of all Romania's imports, and the same amount of its exports, are intra-community oriented. The question that arises is what will happen to te Romania's external trade, if a crisis hits Europe? If countries like Germany, France, Italy, and United Kingdom are hit the hardest in this hypothetical European crisis, Romania will soon follow them. In order to decrease the impact of such possibility, it is necessary to tap new trade opportunities. For this purpose, first we have to analyze the present situation. Based on Eurostat, World Trade Organization, and the Romanian Statistics Institute data from 1999 to 2009, and on the works about trade creation (Balassa 1965, Jovanovic 2005, Molle 2006), the paper wants to point out the aspects of trade concentration in certain regions after the establishment of free trade agreements, and the danger posed by financial crises. This paper analyzes first the situation in the EU27, scanning each member state in order to see the degree of trade relations intra / extra EU. The data will be than compared to another set of analyzes of other four important regions, the Andean Community, ASEAN, MERCOSUR, and NAFTA, whose free trade agreements could support such of comparison with the EU trade relations. The paper follows the assumption that EU27 has the most integrated trade relations among all the analyzed regions. Based on this assumption and on statistical data that points out the percentage change of total imports and exports in the Romanian GDP, some conclusions will be drown out in order to establish some necessary measures to prevent a future crisis, measures that involve the political class, taping new trade opportunities such as Latin American countries, Middle Eastern countries, and South-East Asia, but not forgetting Russia, Romania's former main export partner, establishing clear objectives to future embassy personnel, and a more aggressive advertising campaign in the selected target markets conducted by national agencies.
How to Compute the Liquidity Cost in the Orders-Driven Market?

Review of Finance and Banking , 2011,
Abstract: The paper proposes a new method based on stochastic processes theory in orderto analyze the equilibrium on the financial markets under asymmetrical information. Thepaper proposes an analytical formula for the liquidity cost in the orders-driven market takinginto consideration the presence of the informed and uninformed investors on the market. Thisformula is obtained taking into the consideration the fact that an investor who places a limitorder offers an option to the rest of the market which can be exercised against him.
Annals of the University of Oradea : Economic Science , 2011,
Abstract: The architecture of the Chinese economy began to take shape in the late 1980's, because of the new reforms that the Chinese Communist Party started to take. With the death of Mao Zedong in 1976, the Chinese leadership is taken by Deng Xiaoping, who stated a blitz course in capitalism. The new president encouraged foreign direct investments by creating special economic zones near the costal cities, were foreign companies obtained several tax brakes and other incentives, only to invest in those regions. With the help of statistical data from WTO, IMF, and the World Bank, the current paper analyzes the impact of these special economic zones on the Chinese economy, raging from mutations in the labor market and economic sectors structure and their evolution in the formation of the GDP, FDI inflows, and last but not least external trade and current account situation. On the other hand, the paper tries to make a connection with Romania, computing and predicting, based on the Chinese figures, the way in which the Romanian economy, by creating four economic zones within the counties of Satu Mare, Bihor, Arad, and Constanta, will be able to experience the same growth. The first three counties have been piked up based on their proximity to the Schengen area, and/or on their infrastructure, plain terrain, and a qualified and skilled labour force. Constanta, the only one that resembles with its Chinese counterparts, has been considered because of its capabilities of shipping products right away as they are manufactured. The results would decrease the disparity that exists in revenue levels across Romania, Bucharest leading the group way ahead of the other counties. Foreign direct investments in those areas will attract more others made by the local authorities in the infrastructure (schools, universities, roads, airports, high speed railways). This development will have a direct impact on the current account of the Romania's balance sheet of payments, while its external trade deficit will reduce in time, even transforming in a trade surplus, and helping this way in putting an end to the chronically external debt.
