The Impact Of Exchange Rate Pass-Through On Serbian Export Competitiveness

Abstract

The permanent existence of inflation in Serbia adversely affects achievement of macroeconomic stability. Its effects are reflected in a decrease in the real exchange rate, low price competitiveness of exports and deterioration in the balance of payments. The real exchange rate is an instrument which shows that in conditions of faster growth rate in a country than abroad, the domestic economy can't be competitive in the international market. Implementation of appropriate exchange rate regime inevitably leads to problems of exchange rate changes on import prices and inflation. The research aims to demonstrate the interdependence of inflation and depreciation, and the fact that the general price level increase is a main factor that hinders the realization of the positive effects of the national currency depreciation. Unstable monetary situation in the country undermines the goal of stimulating exports through an increase in the nominal exchange rate and by reducing export prices in foreign currency. Export becomes uncompetitive, while the depreciation of the national currency is quickly spread to inflation through the exchange rate pass-through.

Strategic Management Accounting Role In The Performance Measurement And Control Of Multinational Companies

Abstract

The type and amount of information needed by top management of large companies is primarily determined by the role of individual managers. Thus, managers at the top of the hierarchy in complex enterprises need information that is different from the information managers of individual divisions or strategic business units. Starting from these requirements, strategic management accounting has developed a number of ways to provide information aimed at shaping corporate strategy. In this regard, the paper will be discussed various aspects of performance measurement in multinational companies, as well as the tasks to strategic management accounting should meet within them. Bearing this in mind, the main objective of this paper consists in analyzing the importance of strategic management accounting is to successfully manage the performance of multinational companies. Adequate application of theoretical concepts and research methods chosen, the work is expected to extending domestic literatures in this field meet our economic releases to the role of strategic management accounting in the measurement and control of the performance of multinational companies.

A Giant Exulcerated Phyllodes Breast Tumor - A Case Report

Abstract

Phyllodes tumors of the breast can be benign, malignant, or borderline. Benign and borderline tumors are rare tumor types that have a positive outlook and high survival rate, while the risk of recurrence is typical for malignant breast tumors. Giant phyllodes tumors are larger than 10 cm in diameter and demand a serious diagnostic and treatment approach. In this study we present a case of a female patient treated for an exulcerated breast carcinoma- a giant borderline phyllodes tumor of the breast. Th e patient presented to the department for the right breast lump with ulcerated skin and nipple abnormalities. Th e core biopsy was performed and the patient was diagnosed with a benign tumor. Simple mastectomy was performed and final histopathological report revealed a borderline phyllodes tumor. Diagnosis and treatment of a giant phyllodes tumor remain a great challenge for the surgeons. Establishing the preoperative diagnosis based on histopathological findings is imperative to disease management. Surgery is the mainstay of treatment and mastectomy has been the traditional procedure; in cases where suspicious findings in the axilla are revealed, radical mastectomy is performed and the axilla is to be dissected.

In Vivo Investigation of Soft Tissue Response of Novel Silver/Poly(Vinyl Alcohol)/ Graphene and Silver/Poly(Vinyl Alcohol)/Chitosan/Graphene Hydrogels Aimed for Medical Applications – The First Experience

Abstract

In this paper, we have shown for the fi rst time the soft tissue response of novel silver/ poly(vinyl alcohol)/graphene (Ag/PVA/Gr) and silver/poly(vinyl alcohol)/chitosan/ graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels aimed for medical applications. These novel hydrogels were produced by in situ electrochemical synthesis of silver nanoparticles in the polymer matrices as described in our previously published works. Both Ag/PVA/Gr and Ag/PVA/CHI/Gr, as well as controls Ag/PVA, Ag/PVA/CHI and commercial Suprasorb©hydrogel discs, were implanted in the subcutaneous tissue of rats. Implants with the surrounding tissue were dissected after post-implantation on days 7, 15, 30 and 60, and then processed for histological examination. The tissue irritation index (TIrI) score, according to ISO 10993-6, 2007, as well as the number of leukocytes in the peri-implant zone and connective tissue capsule thickness were examined. The results show that each TIrI score, the leukocyte number around the implanted materials and capsule thickness gradually decreased during the observation period. At the endpoint of follow-up, the Ag/PVA/CHI/Gr implant was surrounded with a thinner capsule, while both the TIrI score and the number of leukocytes of the peri-implant zone were greater compared to the Ag/PVA/Gr implant. Despite the observed differences, we can conclude that our in vivo experiment suggested that both novel hydrogels were biocompatible and suitable for medical use.
