Objectives. Electroconvulsive therapy (ECT) is the most effective treatment for drug-resistant depression (DRD). We estimated the short- and long-term effects of ECT on cognitive functions in patients with unipolar and bipolar DRD. Methods. We investigated 63 patients (18 male, 45 female), aged 34–75 years. Cognitive assessments were performed before, immediately after 6–12 ECT sessions, and 3 months thereafter, using the Benton Visual Retention, Trail Making (TMT), Rey-Osterrieth Complex Figure (ROCF) tests, the Digit Span of the Wechsler Adult Intelligence Scale, and the Rey Auditory Verbal Learning (RAVLT), verbal fluency and Stroop tests. Results. Immediately after ECT, a significant worsening was noted in some indices of memory and verbal fluency. However, 3 months after ECT, the indices of both RAVLT and verbal fluency significantly improved compared to baseline, and those of the Benton and ROCF were significantly better than before ECT. The Digit Span, Stroop and TMT were not affected by the treatment. Conclusions. The negative effects of ECT on the reported measures of cognition are transient. After 3 months, the indices of memory were significantly better than before the treatment. In addition to its antidepressant effect in DRD, ECT may also exert a long-term favourable influence on some cognitive functions. [ABSTRACT FROM AUTHOR]

The article concentrates on the role of European Union (EU) structural funds in the development of small and medium enterprises (SMEs). The analysis presented in this paper is based on the results of computer-assisted telephone interviews conducted with 394 representatives of enterprises localized in three Polish Voivodships: the Podkarpackie, the Lubelskie and the Podlaskie. The entire EU structural funds are based on the assumption that by additionally financing the development of SMEs, they influence regional development indirectly. Even though EU structural funds are not the only factor influencing economic growth and the creation of Gross Domestic Product, they affect the development potential of enterprises indirectly. However, from the perspective of the representatives of researched SMEs, EU structural funds are not so significant for commitment to investment. Actually, for SMEs in Eastern Poland, they have no effect on future investment plans. This bottom-up perspective researched in one of the poorest areas of the EU puts the assumption of the positive relation between the EU structural funds and regional development into doubt.

The objective of this article is to analyze and classify European Union (EU) regions according to human capital and innovativeness. Innovativeness of 225 EU NUTS-2 regions within 2008–2010 is analyzed with special attention paid to human capital. Eighteen indicators of innovativeness and human capital were adapted and transformed into four mutually orthogonal components, with use of factor analysis. The use of factor analysis eliminated the portions of information overlapping in indicators proposed in the beginning of the analysis. It is one of the beneficial differences between the approach presented in this article and the Regional Innovation Scoreboard. A second difference is the scope, for in this article the specific meaning of human capital in the innovation process was highlighted. On this basis the EU regions were classified in five homogeneous groups. It enabled the authors to draw conclusions concerning the areas of innovativeness which need specific support and the potential to be exploited. On the basis of our article concerning the issue of relatively poor innovativeness of some EU regions’ economies, it's worth stressing that underinvestment in the field of human capital is one of the basic causes which determine different results obtained in innovation activity.
