Possibilities for application of comparative advertising and its effects
Economic Annals , 2006, DOI: 10.2298/eka0671090s
Abstract: In recent years, it has been evident that one form of competitive advertising gained in its importance - comparative advertising. Although its extensive use has probably been inspired by the belief that the perception of relative superiority of a brand compared to competition could be encouraged in that way, research evidence suggested mixed conclusions about its effectiveness. The paper summarizes the results of previous studies in this area, and in particular those which point out the factors that can influence effectiveness of comparative advertising. Additionally,, the paper summarizes the opinions of some authors about the long-term influence of this form of advertising on brand, and gives the recommendations for its more effective use. .

Industrija , 2012,
Abstract: Infrastructure investing makes up a significant part of the financial institutions portfolio, and contributes to creating long-term assets cash flows. In addition, infrastructure assets are relatively inelastic in demand and price, and as such the asset has a good performance during the economic downturn. Properly structured infrastructure investments contribute to the diversification of the portfolio, due to the lack of correlation with the yield on bonds, stocks and real estate, and offer good protection against inflation. Applying the concept of project financing involves the application of the most advanced financial techniques and products that are able to ensure only credible international financial institutions and companies. Paper attempts to indicate the presence of financial institutions in project financing of infrastructure, as well as the benefits of this concept in expected to finance infrastructure in Serbia.

Genetika , 2011, DOI: 10.2298/gensr1102397r
Abstract: The paper presents results of eight-year study (1999-2006) of flowering phenophase in 21 introduced sweet cherry cultivars grown under the agro-environmental conditions of West Serbia. Flowering time, as well as progress and abundance of flowering were studied, and classification of the studied cultivars according to flowering time was derived. On the basis of mean several-year overlap in phenophase of full flowering and on the grounds of so far known data on classification of these cultivars among incompatibility groups, we have offered a recommendation for their cultivation in orchards whereby the most effective pollination and fertilization can be ensured as well as good fruit-set and satisfactory fruit yields.

Abstract: We investigate relation between board structure (size and composition) and bank performance in 18 Serbian commercial banks with a dominant shareholder in 2006-2010. We analyze this relation using OLS regression analysis on an unbalanced panel dataset of 75 observations. We find no significant relation between proportion of independent directors on the board and bank performance. We also find no significant relation between bank market performance and board size. We find that bank profitability, measured by ROA and ROE, increase as the number of directors on the board decreases. This result is statistically significant after controlling for endogenous variables and unobserved macroeconomic effects. We conclude that Serbian banks with dominant shareholder should put limits on board size. The relation between bank performance and ownership concentration ratio is always negative, but significant only in case of ROA and ROE.

Abstract: Functional foods are foods that may provide a health benefit beyond basic nutrition. Numerous scientifically proven pieces of evidence in many epidemiological studies indicate that nutrition abundant in certain foods (e.g. fruits and vegetables) is directly correlated with a decreased risk of degenerative diseases. Biologically active compounds in functional foods may impart health benefits or desirable physiological effects. Functional attributes of many traditional foods are being discovered, while new food products are being developed with beneficial components. These results are closely related to nutrition's potentials in preventing chronic diseases. Based on these facts the concept of functional foods has been developed. Rigorous scientific investigation has to confirm the positive physiological effects of these compounds upon health. Labeling claims that are used on functional foods are of two types: (1) structure and function claims, which describe effects on normal functioning of the body, but not claims that the food can treat, diagnose, prevent, or cure a disease (claims such as promotes regularity , helps maintain cardiovascular health , and supports the immune system fit into this category); and (2) disease-risk reduction claims, which imply a relationship between dietary components and a disease or health condition. Structure and function claims do not require preapproval by the FDA, and they require much less stringent scientific consensus than disease-risk reduction claims. Many biologically active compounds are unstable during treatments and storage. They undergo many common chemical reactions such as oxidation, hydrolysis, thermal degradation and Maillard reaction, contributing to the lowering of bioavailability. Anyhow, beneficial effect of bioactive compounds depends directly on the applied treatment in the production of foods.

Abstract: The aim of this investigation was to determine if there were differences: (1) in color Doppler (CD) ultrasound imaging and measurements of periluteal vascularisation in ovary bearing corpus luteum and stromal blood flow of contralateral ovary in ovulatory cycle, and (2) between intraovarian midluteal vascularisation in the group of ovulatory patients and ovarian stromal blood flow of the 21st cycle day in the patients with anovulatory cycles. This prospective clinical investigation involved 205 patients divided into two groups: with ovulatory and anovulatory cycles. CD ultrasound examination of intraovarian vascularisation were performed during menstrual cycle, and CD indices were analyzed: pulsatile index PI, resistance index RI, and systolic/diastolic - S/D ratio. PI was statistically significantly lower in the group of ovulatory patients: 0.8 ± 0.14 vs 1.265 ± 0.41. The same was true for RI ( 0.51 ± 0.04 vs 0.65 ± 0.07) and for S/D ratio (2.08 ± 0.23 vs 2.91 ± 0.58. Resistance to blood flow in periluteal vessels during the midluteal phase was lower than in stromal vessels of nondominant ovary in ovulatory patients (PI 0.8 ± 0.14 vs 2.08 ± 0.31; RI 0.51 ± 0.04 vs 0.74 ± 0.1 and S/D ratio 2.08 ± 0.23 vs 4.25 ± 1.76). Our investigation showed that the resistance to intraovarian blood flow was lower in ovulatory compared to anovulatory cycles. The same was true for intraovarian – periluteal vascularisation in the ovary with corpus luteum compared to stromal vascularisation of nondominant ovary.

Abstract: Background/Aim. In studies that investigate the health effects of short-term air pollution exposure, population-wide changes in acute outcomes such as mortality, hospital admissions and healthcare visits are linked to short-term variations in ambient pollutant concentrations. The aim of this study was to estimate the association between daily outdoor black smoke and sulphur dioxide levels and hospital admissions for cardiovascular and respiratory diseases in Ni , within a period 2001-2005. Methods. A time series analysis was performed using separated regression models for each pollutant and disease group, by age groups and population as a whole. The effects of copollutant, meteorological factors and cyclic oscillations in hospitalization numbers were controlled. Results. A significant increase in hospital admissions was associated with a 10 μg/m3 increase in the concentration of black smoke, for cardiovascular diseases: 3.14% (< 0.01) in children and youth under 19 years of age, 1.85% (< 0.001) in 19-64 age group, and 0.84% (< 0.05) in all ages, and for respiratory diseases: 1.77% (< 0.05) in 19-64 age group, and 0.91% (< 0.05) in all ages. The effects on hospitalizations for respiratory diseases in children and youth under 19 years of age, and for cardiovascular and respiratory diseases in the elderly were not statistically significant. The increase of sulphur dioxide level was associated with the increased number of hospitalizations, for both cardiovascular and respiratory diseases in all age groups, but the influence was not statistically significant. Conclusion. Outdoor pollutants concentrations in urban area of Ni were below regulated limit values during most of the investigated period days but it is shown that even such a level of pollution has a significant effect on hospital admissions for cardiovascular and respiratory diseases.

Abstract: Background/Aim. The inhibition of factor Xa (FX) by the use of low-molecular heparin (LMH) is important clinical procedure in patients with moderate and high risk for the developament of venous thromboembolism (VTE) and pulmonary embolism (PE). The aim of this study was to determine the level of inhibition of FXa by the use of prophylactic doses of LMH nadroparin-calcium and reviparine-sodium which were applied in urological patients with moderate risk for VTE and PE. Methods. The examination included 80 urological patients divided into 4 groups after urological, uroradiological and anesthesiological preoperative preparation and categorization of anesthesiological risk according to the ASA III classification. The first two groups, of 20 patients each, received the recommended doses of LMH in accordance with the preoperative risk, and an inhibition of FXa 48 hours after the surgical operation and four hours after the administration of LMH was determined. Heptest and homogenous anti-Xa test were used for monitoring of FXa inhibition. Since the obtained anti-Xa values were not satisfactory, two more groups were formed and given double the recommended doses. In these new groups, inhibition of FXa was in recommended range. Standard descriptive statistical parameters were used for describing the charateristics of the people from the formed groups. Results. All the patients examined were clinically estimated as patients of moderate risk, for VTE and PE. There were no statistically singificant difference in body weight of the patients who received nadroparin-calcium 0.3 ml and reviparine-sodium 0.25 ml and those who received their double doses, respectively. The level of FXa inhibition in the group in which the dose of nadroparin-calcium of 0.6 ml was applied was statistically significantly higher than in the group which received the dose of 0.3 ml (Mann-Whitney U test: Z = 5.416; p < 0.0001). The level of FXa in the group given reviparine-sodium 0.5 ml was significantly higher than in the group which received the half of this dose (Mann-Whitney U test: Z = 5.416; p < 0.0001). This research did not confirm a statistically significant difference in the levels of FXa inhibition in patients who received nadroparincalcium as VTE and PE prophilaxis in the dose of 0.6 ml and those who received reviparin-sodium 0.5 ml (in two doses of 0.25 ml) (Mann-Whitney U test: Z = 0.163; p > 0.05). Conclusion. According to biochemical monitoring, the recommended doses of LMH are insufficient for the prophylactic inhibition of FXa in urological pateints with moderate risk for VTE

Abstract: Background/Aim. There are a lot of studies aiding to the opinion that the involvement degree of axilla lymph nodes grows depending on increase of breast tumor size, and its histological and nuclear grades. The aim of this study was to assess the risk of axillary lymph nodes involvement, as well as the relation between the tumor size, histological and nuclear grades in a group of female patients who underwent breast cancer surgery, including levels 1-3 axillary dissection. Methods. Investigation covered 900 patients operated on during 2005-2008 who underwent modified radical mastectomy including axillar dissection. We assessed a number of involved lymph nodes, depending on tumor macroscopic size (T), histological grade (HG) and nuclear grade (NG). Results. A total number of examined lymph nodes was 9977. The incidence of involved lymph nodes was from 18.6% with T1 tumor size up to 60.2% with T4 tumor size. Concerning histological grade, the number of involved lymph nodes ranged from 14.2% (HGI) to 45.1% (HGIII); while in terms of nuclear grade, the number of involved lymph nodes ranged from 17.4% (NGI) to 54.5% (NGIV). By using χ2-test for trend and odds ratio (OR), the results showed that the axillary lymph nodes involvement degree was increased with the increase of the tumor size and its histological and nuclear grades. The risk of axillary lymphatic nodes involvement was 1.43 times higher in the group of T2 tumors size compared to the smaller tumors T1 size, and even up to 6.62 times higher in case of T4 tumor size. It was also increasied from 1.79 times for HGII to even 4.98 times for HGIII, and from 1.44 times for NGII to 5.71 times for NGIV. Conclusion. In breast cancer patients, there is a strong correlation between tumor size, its histological and nuclear grades and the risk of axillary lymph nodes involvement.

Abstract: The paper is an attempt to assess the productivity and efficiency on the basis of the information found in financial statements and operating evidence, as well as implementation of the DEA method. The definition of both input and output in banking is absolutely clear, however, an adequate analysis of efficiency in banking requires that the right combinations of input and output be selected Every company has its own principles to implement in its operations. One of the most important is surely the efficiency principle. Relevant academic literature offers various combinations of input and output in testing bank efficiency. The developing countries will find it highly important to monitor bank efficiency and compare it to the countries in the region.
