Planning of communication strategy marketing in cultural-educational institutions for children

Докторска дисертација „Планирање маркетинг комуникационих стратегија у културно-образовним институцијама за децу'' садржи систематизацију теоријских сазнања, насталих на основу резултата досадашњих истраживања маркетинг комуникационих стратегија у култури и културно-образовним институцијама за децу и сазнања из праксе, стечена приликом вишегодишњег рада у институцији културе за децу Градске управе - Града Београда, као и многобројним пројектима за децу и младе. С обзиром да не постоји литература која целовито третира овај проблем, циљ овог истраживања је равномерно третирање културно-образовних институција за децу са другим институцијама културе које су намењене старијој популацији. Проблем који се у дисертацији третира је непостојање свести о тржишном размишљању у институцијама културе за децу, чиме се директно угрожава опстанак институције и њен будући развој. За потребе истраживања, користећи интервјуе, фокус групе, упитнике и студије случаја, анализиране су државне и приватне институције и организације за децу и младе у Србији и региону, са освртом на друге сличне институције и ван региона. Анализирајући проблем примене маркетинг комуникационих стратегија и односа с јавношћу, показало се колико институције за децу планирају и спроводе маркетинг комуникационе стратегије. У раду су приказани и позитивни примери из праксе, ради свеобухватног поређења. У оквиру рада анализиране су и специфичности маркетинг комуникације у области културе и образовања, као и корелација непрофитног маркетинга и односа с јавношћу, која мора да постоји у непрофитној културно-образовној делатности. Да би институција културе за децу стекла конкурентну позицију, мора да задржи постојеће кориснике, да придобије оне који су део потенцијалне публике, али и да пробуди потребу за истим и код такозване непостојеће публике. Препреку у развоју пословања културно-образовних институција представља непостојање довољног броја публике.Doctoral dissertation "Planning of marketing communication strategy in cultural-educational institutions for children'' contains a systematization of theoretical knowledge, created on the basis of previous studies of marketing communication strategies in culture and cultural and educational institutions for children, practical knowledge acquired during many years of work in the cultural institution for children founded by City of Belgrade, as well as numerous cultural projects for children and youth. The goal of this research is equality in treating of cultural-educational institutions for children with other cultural institutions which are intended for older population, given that there is no literature that comprehensively treats this problem. The problem that this dissertation treats is the lack of awareness of the market thinking in cultural institutions for children, which directly threatens the survival of the institution and its future development. For this study, interviews, focus groups, surveys and case studies were used; also, public and private institutions and organizations for children were analyzed, from Serbia and the region, with regard to other similar institutions outside the region. Paper analyzes the problem of implementation of marketing communication strategies and public relations, and shows how institutions for children plan and implement marketing communication strategies. The paper presents positive examples from practice for a comprehensive comparison. The paper analyzes the specificity of marketing communication in the field of culture and education, as well as the correlation between the non-profit marketing and public relations, which must exist in non-profit cultural and educational activities. Cultural institutions for children must gain a competitive position, must retain existing customers and must win potential audience, but also need to awake the cultural need with the so-called non-existent audience. The obstacle to development of cultural-educational institutions is the lack of a sufficient number of audiences. Using integrated marketing communications and public relations, cultural and educational institutions for children can, in cooperation with schools, create children cultural needs, create cultural habits and the form healthier adulthood

Faktori postignuća učenika iz matematike i prirodnih nauka: TIMSS 2019 u Srbiji

Međunarodna studija TIMSS pruža velike mogućnosti za upoređivanje postignuća učenika između zemalja, ali i ispitivanje činilaca koji utiču na postignuće učenika. Važno je istražiti ove činioce jer se na taj način mogu postaviti prioriteti u oblasti obrazovne politike, odnosno usmeravati ljudski i finansijski resursi na one prakse koje najviše vode visokom postignuću učenika.Naziv zbirke: Biblioteka „Pedagoška teorija i praksa” 53Za materijale Međunarodne asocijacije za evaluaciju obrazovnih postignuća (International Association for the Evaluation of Educational Achievement – IEA) koji su prikazani u ovoj knjizi dobijena je dozvola pod brojem IEA-21-021Komisija za ocenu etičnosti u naučnoistraživačkom radu Instituta za pedagoška istraživanja donela je odluku 23. aprila 2021. godine da je tematski zbornik TIMSS 2019 u Srbiji u skladu sa Pravilnikom o etičnosti u naučnoistraživačkom radu Instituta za pedagoška istraživanja

Value added of schools in Serbia

Value added (VA) is one of the measures to assess the quality of school work; when calculating this value, the individual characteristics of students are statistically equalised in order to focus on the factors that are under the jurisdiction of the educational system. The basic value of VA is seen in providing as fair information as possible about the contribution of teachers and / or schools to student achievement. In this paper, we investigate the value added of schools in Serbia. We have set the following research goals: (1) examining the contribution of students' individual characteristics on student achievement in seven subjects, (2) establishing the connection between the student achievement and the expected VA, (3) examining the representation of school groups selected by the expected student achievement and VA and (4) determining the variability of VA of subjects in a particular school. The study was conducted on the sample of 125 elementary schools, with participation of 5065 8th grade students and 5021 parents of these students. Data on student variables were collected through a questionnaire, and from student achievement from the 2011 TIMSS and 2015 final exam databases. Hierarchical modelling was used for the analyses. The results, among other things, show that the expected student achievement and VA are unrelated for most schools, that most schools have both negative VA and below-average expected achievement, and that VA varies between school subjects. The limitations of this study are also given, as well as the implications that the obtained data have on educational policy in Serbia

Trichinella spp. In wild mesocarnivores in an endemic setting

Human trichinellosis and Trichinella infection in pigs are both still endemic in the Balkans, including Serbia. Because of the flow between the sylvatic and the domestic cycle of Trichinella spp., monitoring wildlife has been recommended for the risk assessment of Trichinella spp. infection in swine. We have previously shown the presence of Trichinella infection in wild carnivores including the wolf and the golden jackal, and here we report on Trichinella infection in several other mesocarnivore species. From a total of 469 animals collected between 1994 and 2013, Trichinella larvae were detected in 29 (6.2%, 95% CI = 4.0-8.4) animals, including 14 red foxes (4.7%), 7 wild cats (35%), 5 beech martens (4.8%), 2 pine martens (16.7%), and 1 European badger (6.25%). No Trichinella larvae were detected in the examined specimens of European polecats, steppe polecats and European otters. Species identification of the Trichinella larvae performed for 18 positive samples revealed T. spiralis in 77.8% and T. britovi in 22.2% of the isolates. Both species were detected in red foxes and wild cats. The predominance of T. spiralis in wildlife in Serbia indicates the (past or present) spillover of this pathogen from domestic to wild animals

Analiza kretanja trenda pojave trihineloze svinja pre i posle sistematske deratizacije

In the territory of Serbia, the occurrence of trichinellosis in domestic pigs has been present for a long number of years. In a ten-year period, a total of 1,224 pigs were registered in one populated area with the diagnosis of a larval form of the parasite T.spiralis. In the middle of the period of examination, a systematic deratization of the complete settlement was carried out, the neighboring garbage dumps, and a pit grave. The systematic deratization was performed using the preparation Brodisan. This preparation is a liquid concentrate for the preparation of bait with 0.25% bromadiolone (3-(3-/-bromobiphenyl-4- il/-3-hydroxy-1-phenylpropyl)-4-hydroxycoumarin). The total used quantity of bait for one systematic deratization in this populated area was 4,840 kg. Analyzing the tendency of the incidence of positive pigs in the period before the systematic deratization, we established that the average annual increase was around 70 pigs (b=69.30). The best adapted line of movement of the number of positive pigs was a third degree polynomial (Ŷ=185.20- 304.10x + 147.10x2-16.75x3), because its correlation coefficient is the biggest (rxy=0.96). The analysis of the trend in the number of infected pigs after the systematic deratization was performed in the examined area, it was established on the grounds of the negative parameter b of the straight line trend, that the average annual reduction in the number of infected pigs was 39.80. The tendency of a reduction of the number of infected pigs following the systematic deratization is best described by a second degree polynomial (Ŷ=307.2- 109.23x + 11.57x2) because its correlation coefficient is rxy=0.98.Na prostorima Srbije pojava tihineloze kod domaćih svinja zapaža se duži niz godina. U desetogodišnjem periodu u jednom naseljenom mestu evidentirano je ukupno 1.224 grla svinja kod kojih je dijagnostikovan larveni oblik parazita T. spiralis. Na polovini ispitivanog perioda izvedena je sistematska deratizacija kompletnog naselja, okolnih deponija smeća i jame grobnice. Sistematska deratizacija u ispitivanom naseljenom mestu obavljena je preparatom Brodisan. Ovaj preparat je tečni koncentrat za pripremu mamaka sa 0,25 % bromadiolona (3-(3- /4-brombifenil-4-il/-3-hidroksi-1-fenilpropil)-4-hidroksikumarin). Ukupna upotrebljena količina mamka za jednu sistematsku deratizaciju u ovom naseljenom mestu je 4.840 kg. Analizirajući tendenciju pojave pozitivnih grla svinja u periodu pre sistematske deratizacije ustanovili smo da je prosečno godišnje povećanje iznosilo oko 70 svinja (b=69,30). Najbolje prilagođena linija kretanja broja pozitivnih svinja je polinom trećeg stepena (Ŷ=185,20-304,10x + 147,10x2-16,75x3), jer je njegov koeficijent korelacije najveći (rxy=0,96). Analizom trenda broja inficiranih svinja nakon izvedene sistematske deratizacije ispitivanog naseljenog mesta ustanovljeno je, na osnovu negativnog parametra b iz pravolinijskog trenda, da prosečno godišnje smanjenje broja inficiranih svinja iznosi 39,80. Tendenciju kretanja smanjenja broja inficiranih svinja posle sistematske deratizacije najbolje opisuje polinom drugog stepena (Ŷ=307,2-109,23x+11,57x2) jer je njegov koeficijent korelacije rxy=0,98

Prevalencija četiri gena virulentnosti u sojevima Campylobacter jejuni izoliranima iz mesa brojlera u Srbiji

Campylobacter jejuni is a major cause of human diarrheal disease. The objective of this research study was to determine the prevalence of different virulence genes in isolates recovered from broiler meat at slaughterhouses in Serbia. Out of 115 Campylobacter spp. samples recovered, a total of 35 isolates were identified as C. jejuni on the basis of morphological, biochemical-based detection, multiplex PCR, and sequencing of the highly conserved region of the dnaJ gene encoding the DnaJ Hsp40 family protein. The isolates were screened for the presence of four pathogenic genes, namely flaA, cadF, cdtB, and cgtB, which are responsible for the expression of adherence, colonization, cytotoxin production in C. jejuni, and the onset of Guillain-Barre syndrome. The isolates showed a wide variation in the presence of these genes. All the isolates were positive for flaA. Furthermore, a high genetic heterogeneity in the C. jejuni population was found in this study, showing a pattern partially different from other reported virulence genes. Of the C. jejuni studied, 94.3%, 97.1% and 5.7% were positive for cadF, cdtB and cgtB, respectively. This study provides initial data on the prevalence and distribution of the flaA, cadF, cdtB, and cgtB genes in C. jejuni isolated from broiler meat in Serbia.Campylobacter jejuni vodeći je uzročnik crijevnih bolesti koje se očituju proljevom kod ljudi. Cilj ovoga istraživanja bio je utvrditi prevalenciju različitih gena virulentnosti u izolatima dobivenima iz mesa brojlera u klaonicama u Srbiji. Na prisutnost vrsta roda Campylobacter spp. ukupno je pretraženo 115 uzoraka. Morfološko-biokemijskim pretragama, multipleks PCR tehnikom kao i sekvenciranjem visokoočuvane regije gena dnaJ, koji kodira sintezu proteina DnaJ iz obitelji proteina Hsp40, 35 izolata identificirano je kao C. jejuni. Izolati su pretraženi na prisutnost četiri gena patogenosti: flaA, cadF, cdtB i cgtB. Ti su geni odgovorni za ekspresiju adherencije, kolonizacije, sinteze citotoksina C. jejuni kao i nastanak Guillain-Barreova sindroma. Izolati su pokazali široku varijaciju u prisutnosti tih gena. Svi su izolati bili pozitivni na gen flaA, pri čemu je u populaciji C. jejuni iz ovoga istraživanja utvrđena visoka heterogenost u genetskoj strukturi, koja je djelomice različita od rezultata drugih autora. Kod 94,3 % izolata C. jejuni utvrđen je gen cadF, kod 97,1 % gen cdtB, a kod 5,7 % gen cgtB. Ovo istraživanje pruža početne podatke o prevalenciji i distribuciji gena flaA, cadF, cdtB i cgtB kod C. jejuni izoliranih iz mesa brojlera u klaonicama u Srbiji

Molecular characterization of Listeria monocytogenes isolates from a small-scale meat processor in Montenegro, 2011-2014

The presence of Listeria monocytogenes was evaluated in a small-scale meat processing facility in Montenegro during 2011-2014. L. monocytogenes isolates from traditional meat products and environmental swabs were subjected to a) molecular characterization b) serotyping by both multiplex PCR and next generation sequencing (NGS) c) potential antimicrobial resistance (AMR) was assessed by extraction of specific genes from NGS data and d) screening for the presence of some disinfectant resistance markers. Overall, traditional meat products were contaminated, most likely from incoming raw materials, with 4 major specific STs of L. monocytogenes (ST515, ST8, ST21, ST121) representing 4 clonal complexes (CC1, CC8, CC21, CC121) identified during the four-year period. These strains belonged to serogroup IIa which predominated, followed by IVb (ST515, CC1). The strains from environmental swabs belonged, exclusively, to ST21 and were isolated from cutting board and floor swabs in 2011. Furthermore, we found Tn6188, a novel transposon conferring tolerance to BC, to be specific to sequence type ST121. In addition, antimicrobial resistance genes mprF and fosX were present in clonal complexes CC21 and CC121, while complexes CC8 and CC1 exclusively harbored the mprF antimicrobial resistance gene.This is the peer-reviewed version of the article: Zuber, I.; Lakićević, B.; Pietzka, A.; Milanov, D.; Đorđević, V.; Karabasil, N.; Teodorović, V.; Ruppitsch, W.; Dimitrijević, M.

Higijena procesa klanja i obrade svinja tokom godinu dana na jednoj klanici u Severnobanatskom okrugu u Srbiji

During the validation and verification of HACCP system, a food business operator must use the data obtained in the regular control, whose dynamics and extent are required by actual legislation. During one year, at a cattle slaughterhouse in North Banat District (Serbia), swabs were continually taken from the carcasses of pigs, on the slaughter line after the final wash, in order to monitor compliance with the process hygiene criteria (Salmonella spp., Enterobacteriaceae, total viable count of aerobic bacteria). For 30 consecutive weeks of testing, , Salmonella spp. presence was not detected on the pig carcasses after final wash, while the determined presence of Enterobacteriaceae were 1,05 ± 0,78 log CFU/cm2, and the total viable count of aerobic bacteria were 2.87 ± 0.96 log CFU/cm2. The analysis of the obtained results proved a downward trend in Enterobacteriacae and total viable count of aerobic bacteria presence which proves the effectiveness of the new approach in the monitoring process hygiene during the production of pig carcasses, in accordance with the actual legislation.Tokom validacije i verifikacije HACCP sistema, subjekt u poslovanju hranom, treba da upotrebi podatke dobijene u redovnoj kontroli čija su dinamika i obim propisani odgovarajućom zakonskom regulativom. U periodu od godinu dana na jednoj klanici u Severnobanatskom okrugu, vršeno je plansko uzimanje briseva sa trupova svinja sa ciljem praćenja higijene procesa klanja. Ispitivanjima su bili obuhvaćeni sledeći mikroorganizmi: Enterobacteriaceae i broj aerobnih bakterija, kao i potencijalno prisustvo patogena (Salmonella spp.). Tokom 30 uzastopnih nedelja ispitivanja, na trupovima svinja nakon završnog pranja, nije utvrđeno prisustvo Salmonella spp., dok je prisustvo Enterobacteriaceae iznosilo 1,05 ± 0,78 log CFU/cm2, a ukupnog broja aerobnih bakterija 2,87 ± 0,96 log CFU/cm2. Analizom dobijenih rezultata primetan je opadajući trend nalaza Enterobacteriacae i broja aerobnih bakterija, što ukazuje na efektivnost sistema HACCP i kontrole higijene procesa klanja koja je u skladu sa aktuelnom zakonskom regulativom

Značaj biosigurnosnih mera u primarnoj proizvodnji mesa brojlera

The impact of disease on poultry production is one of the major limiting factors of successful performance in the poultry industry. Biosecurity can be defined as a way to assure safety from the transmission of infectious diseases, parasites and verbs. At the primary production level (broiler breeding) on a farm, the main problem is inconsistent implementation of biosecurity measures, as defined in the biosecurity protocol. Adequate implementation of biosecurity measures on farm depends from the least paid and educated workers and is subject to errors during everyday working practice. Therefore daily monitoring of employees' performance is necessary, with continual education, whereby each detected non-compliance serves to improve the existing biosecurity protocol. Since the prevalence of Salmonella spp. on broiler meat at the slaughterhouse, among other factors, depends on Salmonella spp. prevalence on farm, in cases where technological operations are standardized at the slaughterhouse and when the hygiene level is equable, the data on Salmonella spp. prevalence can help us indirectly to assess adequate implementation of biosecurity measures on farm. In our research, after strict and consistent implementation of biosecurity measures on farm, Salmonella spp. prevalence at the slaughterhouse was reduced from 24% to 10%.Glavni ograničavajući faktor uspešnosti proizvodnje mesa brojlera je negativni uticaj potencijalnih bolesti. Biosigurnosne mere predstavljaju način osiguranja bezbednosti od prenosa infektivnih bolesti, parazita i ostalih uzročnika oboljenja. Na nivou primarne proizvodnje (tov brojlera) na farmi, problem predstavlja nedosledna primena biosigurnosnih mera koje su definisane u biosigurnosnom protokolu. Adekvatna primena biosigurnosnih mera na farmi zavisi od najmanje plaćenih i edukovanih radnika i podložna je greškama tokom obavljanja svakodnevne radne prakse. Stoga je potrebno svakodnevno praćenje izvršenja radnih obaveza zaposlenih, uz kontinuiranu edukaciju, pri čemu svaka otkrivena neusaglašenost služi za unapređenje postojećeg biosigurnosnog protokola. Prevalencija Salmonella spp., na mesu brojlera u klanici, između ostalih faktora zavisi i od nalaza Salmonella spp. na farmi. U slučaju kada su tehnološke operacije na liniji klanja standardizovane i postupak sprovođenja higijene ujednačen, podatak o prisustvu Salmonella spp., može poslužiti za procenu da li su primenjene adekvatne biosigurnosne mere na farmi. U našem radu, nakon striktnog i doslednog preduzimanja biosigurnosnih mera na farmi, prevalencija Salmonella spp. na koži vrata brojlera na klanici, smanjena je sa 24% na 10%
