Summary

From the economic perspective, the western corn rootworm (WCR), Diabrotica virgifera sp. virgifera (Col., Chrysomelidae), poses the gravest threat to the field maize production in Serbia. The purpose of this study is to examine the impact of WCR larvae on the morphology of maize characters during a low-level artificial egg infestation. A field experiment involving the Serbian cultivar ‘NS-640’ was carried out in Bečej, Vojvodina Serbia, in 2016. In the experimental field, a total of 96 maize plants were selected, marked and arranged in 48 pairs. Each pair consisted of an infested plant (WCR eggs injected in the root zone) and an uninfested plant (distillate water injected in the root zone). The number of leaves, height and stem diameter of the plants observed were recorded. Root damage and root weight were measured and evaluated at the end of the trail. For the purpose of statistical analysis, the non-parametric Kruskal-Wallis one-way analysis of variance and a correlation matrix were used. The statistical analysis performed indicate a highly significant difference in the number of leaves and plant height between the infested and uninfested maize plants examined in July (the third field observation). During the last field inspection, significant differences were recorded only between the stem diameters of the infested and uninfested maize plants. A negative correlation was found to exist between the root damage and root weight of the plant pairs. There were positive correlations between the stem diameter, plant height and number of leaves of the infested plants, whereas positive correlations were found between the root damage and plant height of the uninfested plants.

Abstract

We present a new-Keynesian model for small open economy, with price rigidities stemming from a Calvo pricing scheme (1983), monopolistic banking system, financial dollarization of the economy and monetary and fiscal policy governed by rules. We estimate the model on Serbian data and propose various model extensions that could be used for monetary and fiscal policy analysis. We consider 6 combinations of monetary and fiscal policy regimes, inflation targeting and currency peg on one hand, and discretionary cyclically neutral fiscal policy and fiscal rules, on the other. The model with inflation targeting and discretionary fiscal policy fits the data best.

Summary

The complex processes and phenomena that are taking place in the contemporary world require new and adequate methods of acting also in the area of management. This means the need for a fresh approach to the process of organization development and change. This paper presents the key concepts stemming from the psychoanalytic approach to organization and management. Its main aim is to discuss the major categories (concepts) derived from psychoanalytic theories, which pertain to the issues related to organizational change. Theoretical considerations are complemented by presentation of the data collected during interviews with managers from the examined organization and identification of the defence mechanisms of representatives of the organization’s management.

Abstract

: The EMU fiscal system is specific in many areas compared to other classic fiscal systems of national states. Specific features mainly reflect in the implementation of economic policy within the EMU which is carried out by combining a common centralized monetary policy under the ECB jurisdiction and decentralized fiscal policies under the jurisdiction of the member states. The member states` sovereignty in governing their fiscal policies is one of the key causes of the EU fiscal system underdevelopment, i.e. its indigent structure in relation to “standard fiscal systems”.

More indigent structure of the EU fiscal system is reflected in the fact that it consists of only three segments. The first one refers to the EU budget which is also the only instrument for implementing fiscal policy at the supranational level. The second one refers to the harmonization of taxation systems in accordance with inputs and other legislation adopted at the EU level with the aim of fostering the single internal market. Finally, the third segment refers to the fiscal policy coordination of the EMU member states related to appropriate fiscal rules, which mainly stem from the Maastricht convergence criteria and the Stability and Growth Pact.

Summary

The article is dealing with the environmental corporate responsibility. Taking this research topic stems from a growing awareness of entrepreneurs in this area and is associated with the popularity of proving the social responsibility before a group of stakeholders. The article discussed past literature achievements relating to environmental management as one of the areas of corporate social responsibility. There were also presented current imperatives of this aspect, which became the subject of practical research to find effective ways of their compliance. Practical examples of solutions to grouped environmental requirements were described in the second part of the article.

Wpływ ciśnienia różnicowego na wydatek wody złożowej podczas badań rurowymi próbnikami złoża utworów miocenu autochtonicznego w zapadlisku przedkarpackim

Przeprowadzono analizę wyników opróbowań utworów miocenu autochtonicznego wieku baden górny - sarmat dolny w zapadlisku przedkarpackim rurowymi próbnikami złoża. Testy złożowe były wykonywane w nieorurowanych oraz w orurowanych odcinkach odwiertów, z których otrzymano przypływy wody złożowej o różnym stopniu nagazowania, a niekiedy też zanieczyszczonej filtratem płuczki wiertniczej. Łącznie przeanalizowano 57 interwałów wytypowanych metodami geofizyki wiertniczej.

Metodami analizy statystycznej wyznaczono zależność ciśnienia złożowego od głębokości zalegania utworów miocenu, a także zależność początkowego przeciwciśnienia wytwarzanego na te utwory podczas testu RPZ, od głębokości zalegania tych utworów. Natomiast nie stwierdzono korelacji między wydatkiem wody a początkowym ciśnieniem różnicowym.

Dla wybranych 22 interwałów miocenu z rejonu Dębicy uzyskano zadowalającą korelację pomiędzy: wydatkiem wody złożowej a logarytmem naturalnym ilorazu: ciśnienia hydrostatycznego słupa wody przybitkowej w kolumnie próbnikowej i ciśnienia złożowego (w rejonie tym wartość ilorazu ciśnień: php/pz wahała się w bardzo szerokich granicach, tj od 0,05 do 0,57). Stwierdzono również korelację między początkowym przeciwciśnieniem a głębokością pomiaru ciśnienia oraz początkowym przeciwciśnieniem a wydatkiem wody złożowej.

Wyznaczone metodami statystycznymi równania regresji umożliwiają prognozowanie wartości ciśnienia złożowego, początkowej wartości przeciwciśnienia, podczas testów RPZ, wydatku wody złożowej oraz początkowego ciśnienia różnicowego i mogą być wykorzystane przy projektowaniu parametrów technologicznych kolejnych testów złożowych, w analizowanym obszarze zapadliska przedkarpackiego, a w szczególności w rejonie Dębicy.
