Aszimmetriák az Európai Unión belül (Assimetries within the European Union)

A centrum-periféria kapcsolatok elemzése az Európai Unióra is kiterjeszthető. Az integrációs folyamatban jól elemezhetőek a bourdeiu-i tőkeformák, ezek egymásra történő átváltása, a gazdasági és politikai aszimmetriák kölcsönhatása. E kölcsönös kapcsolatokban továbbra is a gazdasági viszonyok meghatározottsága érvényesül. A világgazdasági válság felszínre hozta a történelmi aszimmetriákat, amelyeket a korábbi neoliberális politikák tovább mélyítettek. Az Unión belüli periferális térségekre a válság különbözőképpen hatott. E hatások semlegesítésére többnyire a megszorító gazdaságpolitikákat alkalmazzák. Továbbra is hiányzik azonban egy, a minőségi s nem mennyiségi szempontokat hangsúlyozó fejlesztési politika. Egy ilyen megközelítés a strukturális, intézményi vonatkozásokat erősítené, s ezzel járulna hozzá a periféria termelési, forgalmi, elosztási képességeinek fokozásához. _____ Analysis of centre-periphery relations can be extended to the European Union as well. The capital forms by Bourdieu, their inter-changeability, mutual effects of economic and political asymmetries could be analysed well in the integration process. In these mutual relations economic relations still play the dominant role. The global economic crisis has brought to the surface historical asymmetries, further aggravated by earlier neo-liberal economic policies. Peripheral regions within the Union have been affected in different ways. In order to neutralise these effects austerity measure have been implemented. However, a development policy, emphasising quality and not only quantitative aspects, is still missing. Such an approach would strengthen structural and institutional elements, further enhancing production, trade, and distribution capabilities of the periphery.

Analysis of Hue Spectra During Storage of Pepper (Capsicum annuum)

Color information is widely used in non-destructive quality assessment of perishable horticultural produces. The presented work investigated color changes of pepper (Capsicum annuum L.) samples received from retail system. The effect of storage temperature (10±2°C and 24±4°C) on surface color and firmness was analyzed. Hue spectra was calculated using sum of saturations. A ColorLite sph850 (400-700nm) spectrophotometer was used as reference instrument. Dynamic firmness was measured on three locations of the surface: tip cap, middle and shoulder. Significant effects of storage conditions and surface location on both color and firmness were observed. Hue spectra responded sensitively to color development of pepper. Prediction model (PLS) was used to estimate dynamic firmess based on hue spectra. Accuracy was very different depending on the location. Firmness of the tip cap was predicted with the highest accuracy (RMSEP=0.0335). On the other hand, middle region cannot be used for such purpose. Due to the simplicity and rapid processing, analysis of hue spectra is a promising tool for evaluation of color in postharvest and food industry.

Observing population changes of thrips (Thysanoptera) species damaging forced pepper and their natural enemies

By the strengthening of environmental protection and food safety efforts in Hungary, integrated and especially biological pest control methods should increasingly put forward, for which a solid knowledge on the life course and efficiency of natural enemies applied against certain pests is necessary. Pepper has distinguished significance in domestic vegetable forcing, and the profitability of production is determined primarily by the efficiency of the control of thrips pests. This is why we attached great importance to study what results may be expected by introducing arthropod predators (Amblyseius cucumeris, Orius laevigatus) to control thrips species under domestic conditions on rock wool in a long vegetation period pepper culture. We also liked to find out what kind of role the cultivars play in the change of phytophagous and zoophagous populations. The A. cucumeris predatory mite introduced in late January proved to be effective in controlling thrips pests until mid-April. Despite repeated introductions, the predatory bug O. laevigatus (Heteroptera: Anthocoridae) did not proliferate. Among the three pepper cultivars (Hó, Keceli, Titán) grown at Ráckeve, thrips species proliferated in the highest number on cultivar ‘Hó’, while the population of predatory mites was lowest on the cultivar ‘Titán’, compared to the other two cultivars.
