Vendor Selection and Supply Quotas Determination by Using the Analytic Hierarchy Process and a New Multi-objective Programming Method

In this article, we propose a new methodology for solving the vendor selection and the supply quotas determination problem. The proposed methodology combines the Analytic Hierarchy Process (AHP) for determining the coefficients of the objective functions and a new multiple objective programming method based on the cooperative game theory for vendor selection and supply quotas determination. The proposed methodology is tested on the problem of flour purchase by a company that manufactures bakery products. For vendor selection and supply quotas determination we use three complex criteria: (1) purchasing costs, (2) product quality, and (3) vendor reliability

Modelling and forecasting GDP using factor model: An empirical study from Bosnia and Herzegovina

In the most developed countries the first estimations of Gross Domestic Product (GDP) are available 30 days after the end of the reference quarter. In this paper, possibilities of creating an econometric model for making short-term forecasts of GDP in B&H have been explored. The database consists of more than 100 daily, monthly and quarterly time series for the period 2006q1-2016q4. The aim of this study was to estimate and validate different factor models. Due to the length limit of the series, the factor analysis included 12 time series which had a correlation coefficient with a quarterly GDP at the absolute value greater than 0.8. The principal component analysis (PCA) and the orthogonal varimax rotation of the initial solution were applied. Three principal components are extracted from the set of the series, thus together accounting for 73.34% of the total variability of the given set of series. The final choice of the model for forecasting quarterly B&H GDP was selected based on a comparative analysis of the predictive efficiency of the analysed models for the in-sample period and for the out-of-sample period. The unbiasedness and efficiency of individual forecasts were tested using the Mincer-Zarnowitz regression, while a comparison of the accuracy of forecast of two models was tested by the Diebold-Mariano test. We have examined the justification of a combination of two forecasts using the Granger-Ramanathan regression. A factor model involving three factors has shown to be the most efficient factor model for forecasting quarterly B&H GDP

The Relationship between Capital Structure Choice and Firm\u27s Profitability: Evidence from Bosnia and Herzegovina

This research is designed to examine the relationship between the capital structure and profitability of non-financial firms in Bosnia and Herzegovina during the period of ten years, from 2003-2012. The goal is to prove the existence of the relationship between the firm\u27s capital structure choice and its profitability. The analysis is extended by including the debt structure and differentiating between the types of debt such as the long-term and the short-term ones. The results of the multivariate canonical correlation analysis provide support to a hypothesis that the capital structure and profitability have statistically significant relationships. Furthermore, the findings provide support that firms develop different patterns of profitability depending on the capital structure choice. We found that an increasing proportion of short-term debt and long-term debt in the overall liability of the firm reduces its profitability.

Non-restrictive Relative Sentence as a Parenthetical

U ovome ćemo radu nastojati opisati umetnute nerestriktivne relativne rečenice kao tipične parentetičke strukture. Opis će podrazumijevati njihovu sintaksičku i semantičku interpretaciju, ali i naznake o njihovoj pragmatičkoj ulozi i zasnivat će se na analizi primjera pronađenih u korpusu tekstova koji pripadaju različitim stilovima bosanskoga jezika. Rad je podijeljen u tri dijela. U prvom ćemo dijelu definirati parentetike i dati pregled dosadašnjih pristupa u analiziranju te pojave. U drugome dijelu rada fokusirat ćemo se na definiranje i analizu umetnutih nerestriktivnih relativnih rečenica, a u trećem će se dijelu izdvojiti najznačajnija zapažanja.In this paper, we will seek to describe inserted non-restrictive relative sentences as typical parenthetical structures. The description will include their syntactic and semantic interpretation, as well as indications about their pragmatic role, and will be based on an analysis of examples found in a corpus of texts belonging to different styles of Bosnian language. The paper is divided into three parts. In the first part, we will define parentheticals and give an overview of the approaches taken so far in analyzing this phenomenon. In the second part of the paper, we will focus on defining and analyzing the inserted non-restrictive relative sentences, and in the third part, we will highlight the most significant observations

VERB PHRASES IN BOSNIAN AND THE SYNTACTIC PROCESS OF ELLIPSIS: SIMILARITIES AND DIFFERENCES BETWEEN BOSNIAN AND ENGLISH

U ovom se radu analizira struktura glagolske sintagme u bosanskom jeziku te se nastoji odrediti bazni položaj upravnih članova sintagme, njihovih argumenata, ali i adjunkta. Ponašanje strukturnih elemenata koji čine glagolsku sintagmu u bosanskom jeziku i mogućnost njihovog pomjeranja prati se u procesu deriviranja površinske strukture rečenice koja sadrži elidirano mjesto. Različita ostvarenja elipse objašnjavaju se jedinstvenim položajem pojedinih strukturnih elemenata i njihovom mogućnošću da projiciraju zasebne maksimalne projekcije koje, u procesu deriviranja površinske strukture rečenice, mogu biti ili obuhvaćene elipsom ili izbjeći elidiranje. U vezi s tim, u radu se ukazuje na različito ponašanje pojedinih vrsta glagola u procesu VP elipse u bosanskom jeziku, te se uspostavlja paralela s istim strukturnim elementima u engleskom jeziku. U radu se analiza navedenih pojava zasniva na principima i parametrima generativne gramatike.In this paper, by applying the comparative method, we attempted to point out the similarities and differences in the verb domain between the Bosnian and the English language. With respect to this, the possible argument structure of the verb phrase (VP) in the Bosnian language was analysed, as well as the behaviour of structural elements in the syntactic process of ellipsis. It was concluded that the VP ellipsis in the Bosnian language occurs very high up in the sentence structure, after the elements with strong features check those features. Also, the analysis carried out showed that in the Bosnian language auxiliary and modal verbs are not base generated in the same position, and that modal verbs, unlike in English, are generated lower than the enclitic forms of auxiliary verbs and can be elided. While VP ellipsis in Bosnian necessarily includes lexical verbs, with modal verbs being optionally elided, auxiliary verbs in their enclitic form remain outside the elided place. However, a special type of TP ellipsis in the Bosnian language also eliminates the enclitic form of the auxiliary verb, and only the subject with the feature of non-contrastive focus is realized phonetically in the sentence structure

Statistical analysis of causality between capital structure and firm profitability: Evidence from Bosnia and Herzegovina

This research is designed to examine the relationship between the capital structure and profitability of non-financial firms in Bosnia and Herzegovina during the ten years period, from 2003-2012. The goal is to prove the existence of the relationship between the firm\u27s capital structure choice and its profitability. The analysis is extended by including the debt structure and differentiating between the types of debt such as the long-term and the short-term ones. Canonical correlation and multiple regression analysis are used. The results of the multivariate canonical correlation analysis provide support to a hypothesis that the capital structure and profitability have statistically significant relationships. Furthermore, the findings provide support that firms develop different patterns of profitability depending on the capital structure choice. We found that an increasing proportion of short-term debt and long-term debt in the overall liability of the firm reduces its profitability

New multidimensional approaches to poverty measurement in Bosnia and Herzegovina

Unlike the standard unidimensional poverty indices, based mostly on monetary poverty measures, multidimensional poverty indices may include numerous non-monetary poverty indicators. This study utilized fuzzy and Alkire – Foster (AF) and fuzzy methodology to assess the poverty level in Bosnia and Herzegovina (B&H) and to compare the results with official poverty assessments. In addition to consumption as a monetary measure, we constructed AF and fuzzy indices by including numerous non-monetary measures that indicate housing quality, possession of durable goods and the household structure. AF multidimensional indices for B&H are calculated based on data from Household Budget Surveys (2004, 2007 and 2011) and fuzzy poverty indices are calculated based on data from HBS 2011. This research has found the differences in the values, direction and dynamics between unidimensional and multidimensional approaches to poverty measurement. Authors state that it is not sufficient to base the creation of more efficient social policies and poverty reduction strategies exclusively on unidimensional indices that address just one dimension of poverty

Incidencija epileptičnih napadaja tijekom i nakon moždanog udara u desetgodišnjem razdoblju na Neurološkoj klinici Kliničkoga centra Univerziteta u Sarajevu

Association between epilepsy and stroke has been known since 1864. The pathophysiological basis of epileptic seizures during and after stroke is molecular changes that occur in ischemia as primary events and in hemorrhage as secondary events. The aim of the study was to determine the incidence of epileptic seizures during and after stroke, recorded over a 10-year period at the Department of Neurology, Sarajevo University Clinical Center. The study covered the period from January 1, 1989 till December 31, 1998. During the period, 7001 patients were treated at the Department. Cerebral thrombosis predominated (53.6%), whereas there were only 17.25% of patients with cerebral embolism, 21.96% with intracerebral hemorrhage, and 7.17% with subarachnoid hemorrhage. The incidence of symptomatic epileptic seizures for total patient sample according to years ranged from 0.75% to 6.67%. According to type of insult, the incidence of symptomatic epileptic seizures was 1.0%-3.37% for cerebral thrombosis, 1.22%-6.67% for cerebral embolism, 0.65%4.05% for intracerebral hemorrhage, and 1.34%-4.34% for subarachnoid hemorrhage. Associated epileptic seizures, i.e. the seizures accompanying the onset of stroke, were not included in the study. Results of the study showed that there were 75 patients with symptomtic epileptic seizures (47 with late seizures and 28 with early seizures, or 1.998% of total patient sample) during the 10-year period of observation. There were 36 cases of cerebral embolism (23 and 13 in the group of late and early seizures, respectively; 2.980%), 30 cases of intracerebral hemorrhage (23 and seven with late and early seizures, respectively; 1.951%), and seven cases of subarachnoid hemorrhage (four with late and three with early seizures; 1.394%). According to stroke types and subtypes, hemorrhagic stroke was found to be a more common etiologic factor for the occurrence of early and late symptomatic epileptic seizures, whereas cerebral embolism in ischemic stroke was a more common cause of symptomatic epileptic seizures than cerebral thrombosis. During the study period, the years 1993, 1994 and 1995 were characterized by a small number of patients with symptomatic early and late epileptic seizures (9 in total). The incidence of early and late epileptic seizures in the sample of stroke patients during the study period ranged from 1.394% to 2.980%.Veza između epilepsije i moždanog udara poznata je još od 1864. godine. Patofiziološka osnova epileptičnih napadaja tijekom i nakon moždanog udara su molekularne promjene koje u ishemiji nastaju primarno, a u hemoragiji sekundarno. Cilj ovoga rada bio je utvrditi incidenciju epileptičnih napadaja tijekom i nakon moždanog udara u desetgodišnjem razdoblju na Neurološkoj klinici Kliničkoga centra Univerziteta u Sarajevu. Obuhvaćeno je razdoblje od 1. siječnja 1989. do 31. prosinca 1998. godine, tijekom kojega je na Klinici liječen 7001 bolesnik. Najviše je bilo cerebralnih tromboza (53,65), potom cerebralnih embolija(17,25%), intracerebralnih hemoragija (21,96%) i subarahnoidnih hemoragija (7,17%). Incidencija simptomatskih epileptičnih napadaja u pojedinim godinama kretala se za ukupan uzorak od 0,75% do 6,67%. Prema tipovima inzulta incidencija je bila kako slijedi: za cerebralnu trombozu 1,0%-3,375%; za cerebralnu emboliju 1,22%-6,67%; za intracerebralnu hemoragiju 0,65%-4,05%; i za subarahnoidnu hemoragiju 1,34%-4,34%. U studiju nisu bili uključeni asocirani epileptični napadaji (napadaji kojima je započinjao moždani udar). Na temelju ispitivanja zaključeno je da je u desetgodišnjem razdoblju na Klinici bilo 75 bolesnika sa simptomatskim epileptičnim napadajima (47 bolesnika s kasnim napadajima i 28 bolesnika s ranim napadajima ili 1,998% od ukupnog uzorka naših bolesnika tijekom promatranog razdoblja). Bio je 36 bolesnika s cerebralnom embolijom (23 u skupini s kasnim napadajima i 13 u skupini s ranim napadajima; 2,980%), 30 bolesnika s intracerebralnom hemoragijom (23 u skupini s kasnim napadajima i 7 u skupini s ranim napadajima; 1,951%) i sedmoro bolesnika sa subarahnoidnim krvarenjem (4 u skupini s kasnim napadajima i 3 u skupini s ranim napadajima; 1,394%). Prema tipovima i podtipovima moždanog udara utvrđeno je daje hemoragijski moždani udar u našem kliničkom materijalu bio češći etiološki čimbenik za nastanak simptomatskih ranih i kasnih epileptičnih napadaja, dok se cerebralna embolija u ishemijskim inzultima i na našem materijalu pokazala kao češći razlog pojave simptomatskih epileptičnih napadaja u odnosu na cerebralnu trombozu. Tijekom promatranoga razdoblja mali je broj bolesnika sa simptomatskim ranim i kasnim epileptičnim napadajima (ukupno 9) zabilježen u godinama 1993., 1994. i 1995. Na temelju rezultata ovoga ispitivanja zaključeno je da se je incidencija epileptičnih napadaja u ukupnom uzorku bolesnika s moždanim udarom u desetgodišnjem razdoblju kretala od 1,394% do 2,980%
