The Split-SV model
No full textA modification of one of the most popular stochastic model in describing financial indexes dynamics is introduced. For describing a nonlinear behavior of volatility, a threshold noise indicator in the autoregressive time series of stochastic volatility is used. Toward this end, the model named the Split-SV model is introduced and its basic stochastic properties are investigated. Furthermore, the Empirical Characteristic Function (ECF) method is used for obtaining the parameter estimations of the model and a numerical simulation of the obtained estimates is given as well. Finally, the Split-SV model is applied for fitting the empirical data: the daily returns of the exchange rates of GBP and USD per euro

The analysis of the level of training of intervention police units of The Ministry of the interior of the Republic of Serbia
Get PDFU radu se želi odgovoriti na pitanja: (1) koliko su pripadnici Interventnih jedinica policije (IJP) obučeni za obavljanje namenskih zadataka? (2) postoji li uticaj nekih karakteristika pripadnika IJP na nivo njihove obučenosti? Podaci koji su korišćeni u analizi prikupljeni su pomoću kombinovanog instrumenta – anketnog upitnika i testa. Instrument je sadržao šest pitanja anketnog tipa kojima su prikupljani podaci o uzorku i deset pitanja u vidu testa. Tačan odgovor na svako postavljeno pitanje bodovan je sa jednim poenom. Nivo znanja ispitivanih pripadnika IJP izražen je sumom osvojenih bodova. Ispitivanje je bilo anonimno, a pristupilo mu je 90 pripadnika IJP koji su odabrani slučajnom metodom. Prikupljeni podaci obrađivani su statističkom metodom, pri čemu je korišćeno više tehnika, i to: 1) standardne deskriptivne tehnike; 2) jednofaktorska analiza varijanse ANOVA; 3) jednofaktorska multivarijaciona analiza varijanse MANOVA. Rezultati prezentovani u radu ukazuju da pripadnici IJP imaju solidan nivo znanja o poslovima koje obavljaju. Ipak, ostaje dosta prostora da se taj nivo podigne, imajući u vidu da su analize ukazale da postoji uticaj nekih karakteristika pripadnika IJP na nivo njihove obučenosti. To su stepen stečene stručne spreme, formacijska dužnost u IJP definisana stručnom spremom i broj obuka za poslove IJP kojima je ispitanik prisustvovao. Sve navedene karakteristike ispoljavaju veliki uticaj.This paper aims to answer the following questions: (1)
how well the members of the Intervention Police Units (IPU) are
trained for performing dedicated tasks, and (2) whether there is
the influence of some characteristics of members of the IPU on
the level of their training. The data used to perform the analysis
were collected using the combined instrument – a survey questionnaire and a test. The instrument contained 6 survey-type questions used to collect data on the sample and 10 test questions. The
correct answer to each question was given one point. The level of
knowledge of the surveyed members of the IPU was expressed
by the sum of the achieved points. The survey was anonymous
and 90 randomly chosen members of the IPU participated in it.
The collected data were processed by a statistical method, at which several techniques were used, namely: 1) standard descriptive
techniques; 2) single factor analysis of variance ANOVA, and 3)
single factor multivariate analysis of variance MANOVA. The results presented in the paper show that the members of the IPU
have considerable knowledge about the tasks they do. However,
there is still much room for improving that level bearing in mind
that the analyses showed that there was influence of some characteristics of the IPU members on the level of their training. These
are the degree of achieved professional qualification, formation
duty in the IPU defined by professional qualification and a number of training of respondents for the IPU operations. All listed
characteristics demonstrate considerable influence
Condition analysis of road safety in local goverments in depending of the demographic characteristics, economic standards of population and vehicles age
Get PDFАнализа стања безбедности саобраћаја је део праћења стања безбедности саобраћаја које доприноси успостављању система безбедности саобраћаја и управљању безбедношћу саобраћаја на одређеном подручју. Са аспекта демографских обележја у раду је извршена анализа вредности релативних показатеља који узимају у обзир број становника. Такође,
анализирана је и вредност пондерисаног јавног ризика у зависности од старости становништва. Анализа стања безбедности саобраћаја из угла економског стандарда становништва, вршена је поређењем индекса развијености локалних самоуправа и вредности пондерисаног јавног ризика, са полазном хипотезом да подручје које има неповољнију позицију са аспекта економског стандарда становништва има и неповољнију позицију посматрано са аспекта безбедности саобраћаја. У оквиру анализе безбедности саобраћаја у зависности од старости возила, анализиран је утицај просечне старости возног парка и проценат младих путничких аутомобила у односу на вредност пондерисаног јавног ризика.Condition analysis of road safety is a part of the monitoring of road safety which contributes to establishing a system of road safety and road safety management in the given area. Regarding demographic characteristics of the paper has analyzed the values of relative indicators that take into consideration the number of inhabitants. Also, has been analyzed the value of public risk weighted depending on the age of the population. Condition analysis of road safety from the point of economic standards of the population, was used to compare the development index of local governments and weighted public risk values, with the starting hypothesis that the area has a bad
situation in terms of the economic standard of the population has a bad situation from the aspect of road safety. The analysis of road safety, depending on the vehicle age, the influence of the average age of the fleet and the percentage of young passenger cars in relation to the value of weighted public risk.Conference Journal.

Znanje učenika srednjih škola u Beogradu kao element spremnosti za reagovanje na poplave
Get PDFThe consequences of the floods that inundated the territory of Serbia in 2014 indicated a high level of citizen unpreparedness to respond to the situation. Starting from this fact, the basic idea of this research is to examine the level and correlation of certain factors with the students' knowledge about floods as natural disasters. The aim of the research is a scientific explanation of the correlation between students' knowledge about floods and these factors. The research consisted of a survey conducted on a sample of 3,498 respondents who make up 8.96% of the students population. The respondents were students from 19 secondary schools, out of a total of 54 at the territory of 11 affected municipalities of the city of Belgrade. The research results suggest that flood related knowledge is influenced by the students' gender, education and employment status of parents, education acquired in school and in the family, while the knowledge of safety procedures for responding to floods is influenced by fear, gender and the educational level of parents. These results can be used in creating educational programme strategies to enhancing preparedness for response.Posledice poplava koje su zahvatile teritoriju Srbije tokom 2014. godine ukazale su na visok nivo nespremnosti građana za reagovanje u nastaloj situaciji. Rukovodeći se time, osnovna ideja ovog istraživanja je da se ispitaju nivo i povezanost određenih faktora sa znanjem učenika o poplavama kao prirodnim katastrofama. Cilj istraživanja predstavlja naučna eksplikacija povezanosti znanja učenika o poplavama i spomenutih faktora. Istraživanje je ostvareno metodom anketiranja, na uzorku od 3498 ispitanika, koji čine 8,96% populacije. Ispitanici su učenici 19 srednjih škola od ukupno 54, koliko ih ima na teritoriji 11 ugroženih opština Grada Beograda. Rezultati istraživanja ukazuju na to da na znanje o poplavama utiču pol učenika, obrazovanost i zaposlenost roditelja, edukacija u školi i porodici, dok na poznavanje bezbednosne procedure za reagovanje prilikom poplava utiču strah, pol i obrazovanost roditelja. Navedeni rezultati mogu se iskoristiti prilikom stvaranja strategija obrazovnih programa, što bi doprinelo unapređenju spremnosti za reagovanje u uslovima prirodnih katastrofa izazvanih poplavama

Bioremediation Potential Assessment of Plant Growth-Promoting Autochthonous Bacteria: a Lignite Mine Case Study
Get PDFCoal and lignite play a major energy supply role in many European countries, including Bosnia and Herzegovina. Yet mining activities are a heavy source of ecosystem contamination, posing significant environmental threats. The primary goal of this study was to isolate and identify autochthonous lignite mine spoil bacteria and evaluate their potential in bioremediation of these polluted soils. Two Bacillus species, Bacillus simplex and a Bacillus cereus group member, were identified using conventional, molecular, and bioinformatics approaches. This represents, to our knowledge, the first microbial characterization of mine overburden in Bosnia and Herzegovina. A co-inoculum of autochthonous bacterial populations was used to treat unvegetated as well as oat- and lettuce-vegetated lignite overburden samples. Our results illustrate the potential of recovered native species to enrich soil fertility and productivity through plant growth promotion
Performance Analysis of Wireless Systems in the Presence of k-mu Short Term Fading, Gamma Long Term Fading and k-mu Cochannel Interference
No full textWireless communication system operating over Gamma shadowed multipath fading channel in the presence of cochannel interference subjected to small scale fading is delineated in this paper. Desired signal experiences Gamma long term fading, k-mu short term fading and cochannel interference affected by k-mu multipath fading. In interference limited environment, the signal to interference ratio (SIR) for proposed wireless communication system can be calculated as the ratio of product of square rooted Gamma random variable and k-mu random variable and k-mu random variable. The probability density function (PDF), moments and moment generating function of signal to interference ratio will be calculated as expressions in the closed form. The impact of Rician factor of desired signal and Rician factor of cochannel interference on moments will be analyzed and discussed
Praksa Evropskog suda za ljudska prava i krivična dela terorizma
Get PDFThe development of approaches to the use of criminal repression, in the context of substantive criminal, law for many years, was a question a lot of controversy, both in defining the crime of terrorism, and with setting the boundaries of criminal repression in this area. Terrorism, which essentially has the potential to undermine democracy and the rule of law by encouraging autoriternih tendency of authorities to fight this negative social - pathological phenomena, imposing views of the minority to the majority, without limits in achieving their goals, more than any other part of the world has hit Europe, which through its mechanisms, including the European court of Human rights and its practice, has developed specific counter-measures aimed at ensuring the libertarian political and cultural values of Europe. The rulings and case law related to combating terrorism have been set certain principles relating to the establishment of a balance between the effective response of the state and protection of human rights. Terrorism attacks the basics of democracy and the rule of law, a state against these attacks need to defend themselves while balancing the need to respect human rights and the response to terrorism.Razvoj pristupa u korišćenju krivičnopravne represije u okviru materijalnog krivičnog prava, dugi niz godina, bilo je pitanje puno kontroverzi, kako u vezi sa definisanjem samog krivičnog dela terorizma, tako i sa postavljanjem granica krivičnopravne represije u ovoj oblasti. Terorizam koji u svojoj suštini poseduje potencijal da podrije demokratiju i vladavinu prava pospešivanjem autoritarnih tendencija vlasti u borbi protiv ove negativne socijalno - patološke pojave, nametanjem stavova manjine većini, bez granica u ostvarivanju svojih ciljeva, više nego bilo koji drugi deo sveta pogodio je Evropu, koja je kroz svoje mehanizme uključujući Evropski sud za ljudska prava i njegovu praksu razvila određene kontraterorističke mere namenjene obezbeđivanju slobodarskih političkih i kulturnih vrednosti Evrope. U presudama i praksi Suda u vezi sa suprotstavljanjem terorizmu postavljeni su određeni načelni principi, koji se odnose na uspostavljanje ravnoteže između efikasne reakcije države i zaštite ljudskih prava. Terorizam napada osnove demokratije i vladavine zakona, a države protiv ovih napada moraju da se brane uz balansiranje potrebe poštovanja ljudskih prava i odgovora na terorizam
