Effects of the Low-Level Western Corn Rootworm Egg Infestation on Maize Plants in the Field

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.

Essential Oil Composition, Total Phenolic Content, and Antioxidant Activity - Determined from Leaves, Flowers and Stems of Origanum Vulgare L. Var. Aureum

Abstract

Origanum vulgare L. var. aureum is an aromatic medicinal plant belonging to the Lamiaceae family, rich in essential oils and antioxidants. Its specific chemical composition represents an important source of biologically active principles with diverse applications in food products and nutraceuticals. The aim of this study was to determine the differences between chemical composition of volatile oils, phenolic content and antioxidant activity of different plants parts: leaves, flowers, and stems. Essential oils from leaves and flowers had similar compositions with only few differences between γ-terpinene and trans-ß-ocimene. Total phenolic content and antioxidant activity were determined for the hydro-alcoholic extract obtained from post-distillation oregano waste material. The total phenolic content was determined using Folin-Ciocalteu reagent and varied from 3173 to 6522 mg GAE/L. The major compounds identified by HPLC were syringic acid, pyrocatechol, and catechin. Furthermore, all extracts showed high antioxidant activity, ranging from 31.3 to 44.5 mg GAE/L, with an inhibition percent varying from 63.1 to 88.6%.

Estimated DSGE Model for Monetary and Fiscal Polic Coordination Analysis – The Case of Serbia

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.

Psychodynamic Perspective of Organizational Change

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.

Innovation, Innovativeness And Gender - Approaching Innovative Gender

Abstract

This paper deals with the attempt to search for the sources of creativity in the broad sense in solving problems. These creative solutions become innovations. The ability to develop innovation depends on the multi-dimensional predispositions to solve problems – those found in people, inspired by the market, organised or spontaneous, as well as facilitated or hampered by the state. Yet, the aforementioned factors should be supplemented with one more – gender. In the chapter attention is paid to the multi-dimensional differences stemming from gender, which should be perceived as a positive element, because they are the source of synergy resulting from collaboration among research or business teams in the process of innovation. The chapter introduces the concept of ‘innovative gender’ and its institutional framework. The methodological inspiration is the model known in the literature as the Innovation Genome, the conceptualization of which constitutes a major part of the study.

Analysis of Fiscal Rules in the European Monetary Union

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.
