Romanian textiles and clothing industry – present and perspectives

In January 2007 Romania joined the EU. Since then its current import duties for clothing and textiles has dropped a full 10% to between 6% and 8%. Consequently, import and re-export opportunities for Hong Kong, the Chinese mainland and other Asian suppliers are expected to increase, according to local Romanian importers. Chinese mainland firms are said to have invested US $254 million in the Romanian economy, but no details are available about the proportion directly invested in the clothing and textile sectors. Romania is now a lesser force in the garment and textile industry than it used to be, where it comes to feeding the EU market - even though the country is still the largest producer of such goods in Central and Eastern Europe, ahead of comparable economies such as Ukraine and Bulgaria. Romania also easily outcompetes more expensive labour in Hungary and Poland, neither of which are now considered contenders for price-sensitive trades, say Romanian analysts.price-sensitive trades, clothing industry, Romanian textiles

Aspects Reffering to Utility and Risk of Investments Decision Systems

The explanation of investment behaviour in the light of expected utility it meant an important step in the substantiation of the theory regarding investment portofolio. It was demonstrated that the linear form of utility function excludes certain decisive decisions (Allais’s paradox), so that in a short period of time from Neumann- Morgenstein’s hypotheses specialists’ attention directed to finding a utility function that would explain as well as possible the relationship with the risk in investment behaviour. The most important contributions on this issue are more recent, from 1980: The hypotheses of „expected diminished utility” of MacCrimmon (1979) and Machina(1982), the hypotheses of „ non-linear expected utility” of John Quiggin (1993), the hypotheses of „ conditional expected utility”, sustained by Chew, Karni si Safra in 1987, the hypotheses of „non-additivity expected utility” of Fishburn (1988) or the hypotheses of „expected utility based on investment behaviour”, brought by Machina (1988).investment behaviour, expected utility, risk, investors’ preference axiom

Seronegative Myasthenia Gravis with Concomitant SARS-CoV-2 Infection in a Dog

Myasthenia gravis (MG) is a disorder of neuromuscular transmission affecting the neuromuscular junction. The majority of cases involve an autoimmune attack against AChR, but a limited number of patients are seronegative for AChR antibodies. Viral infection is incriminated as a trigger for MG occurrence, and in a limited number of reports, infection with SARS-CoV-2 was found to be associated with MG expression in humans. In this report, we describe case of seronegative generalized MG in a 2-year-old crossbred female dog associated with SARS-CoV-2 infection due to close exposure to an infected owner
