Furthermore, the study compares results from Pearson Correlation and Mutual Information and Information Gain ratios to drawn new conclusions on the perceptions of Greek I.T. start-up founders. The findings indicate that use of Mutual Information reveals a set of factors that contribute to entrepreneurial perception of success which differs significantly from the conclusions based on Correlation Coefficient Analysis. More specifically factors such as Operation Years and Previous Start-Ups play a far more crucial role than B2B and Sales. The study offers an original contribution to entrepreneurial science, introducing the use of entropy-based mathematical ratios, such as Mutual Information and Information Gain in Entrepreneurial Research. The study highlights that use and results derived of such ratios enable researchers to identify more information regarding (non-linear) relationships between variables, compared to Correlation Coefficient methods.","PeriodicalId":55690,"journal":{"name":"Oeconomica Jadertina","volume":"18 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139007353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

S obzirom da se većina hrvatskih prvoligaških nogometnih klubova pretežno financira prodajom registracija igrača, korisno je znati koliko se procjene vrijednosti tog portala razlikuju od stvarnih odšteta plaćenih prilikom izlaznih transfera, ali i koliko se nogometaša iz HNL-a zaista transferira uz financijsku naknadu. Analizirajući domaće prvoligaške klubove u razdoblju od deset natjecateljskih sezona u ovom je radu utvrđeno kako većina igrača (najmanje 55%, ali vjerojatnije 85%) napušta svoje klubove bez plaćene odštete. Zbog toga je ukupna vrijednost transfera do 40% niža od procjene ukupne tržišne vrijednosti koje su ti igrači u trenutku odlaska imali na Transfermarktu. Međutim, ako se u obzir uzmu samo transferi s plaćenom odštetom, njihova se vrijednost gotovo u potpunosti podudara s procjenom tržišne vrijednosti na Transfermarktu - odstupanje iznosi samo 1,5%. Potvrđena je jaka i značajna statistička veza između procjene tržišnih vrijednosti i transfernih vrijednosti, ali samo za one izlazne transfere u kojima je zaista plaćena naknada. Vjerojatnost plaćenog transfera raste s rastom tržišne vrijednosti - pogotovo iznad milijun eura po igraču - a povećana tržišna vrijednost povećava i točnost procjene vrijednosti samog transfera. Budući da rezultatski uspješniji domaći klubovi u svojim redovima imaju više nogometaša s većom tržišnom vrijednošću, za njih su procjene Transfermarkta preciznije nego za manje uspješne klubove.","PeriodicalId":55690,"journal":{"name":"Oeconomica Jadertina","volume":"74 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139008177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zbog toga su se nastavnici našli u nepovoljnoj situaciji i susreli se s nizom izazova koje su morali prevladati u što kraćem roku ne narušavajući kvalitetu online nastavnog procesa. Iz navedenog proizlazi cilj ovoga rada koji se ogleda u sagledavanju izazova u online nastavi za vrijeme pandemije iz perspektive visokoškolskih nastavnika iz šest europskih zemalja. U tu je svrhu od svibnja do listopada 2021. provedeno online istraživanje s pomoću strukturiranoga anketnog upitnika na uzorku od 525 nastavnika visokoobrazovnih institucija iz šest europskih zemalja. Rezultati su pokazali da se najveći izazovi s kojima se nastavnici susreću u online okruženju uglavnom odnose na provedbu ispitivanja i poznavanje rada putem određenih softvera i aplikacija. U online poučavanju nastavnicima je najizazovnije bilo studentima prenijeti znanja koja se tiču općih vještina poput sposobnosti samostalnog rada, vještina rješavanja problema, vještina prikupljanja i obrade podataka, ali i vještina koje se odnose na učenje, primjerice kako se pripremiti za predavanje te kako pisati i čitati znanstvene radove. S obzirom na širok spektar izazova s kojima su se nastavnici morali suočiti, pozitivno je da su uglavnom sve izazove mogli riješiti samostalnim pronalaženjem informacija na webu i konzultacijama s kolegama, a od velikog značaja bila im je i pomoć sveučilišta, fakulteta i tehničke službe.","PeriodicalId":55690,"journal":{"name":"Oeconomica Jadertina","volume":"28 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139009130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explore the regulatory framework, procedures, scope, and objectives, while interviewing auditing experts for insights into challenges and opportunities. Findings reveal procedural dominance in current implementation of the Law. Focus on accounting neglects crucial functional departments. The audit committee's role and composition raise independence concerns. Understaffing further hampers operations. A significant weakness appears in the independence of the audit. Internal auditors report to the hospital administrator and participate in the audit committee. The appointment and remuneration of auditors is not based on the auditor's competence and suitability, but on a cost basis. The question therefore arises as to whether the auditor performs the duties objectively and impartially in accordance with the International Institute of Internal Auditors' standards. Furthermore, regarding the research question on the role of the internal auditor and the treatment by auditees, there has been a significant improvement as evident by the respondents’ answers.","PeriodicalId":55690,"journal":{"name":"Oeconomica Jadertina","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139007653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emphasizing the pivotal role of message content, the authors present a hypothesis depicting the profound impact of narration, characters, and sentiment in the communication process. These components wield significant influence over the emotional facets of decision-making, influencing the process or prompting alterations to initial decisions. Critically challenging established economic paradigms, the article underscores the indispensable emotional dimension inherent in communication. Drawing upon the scholarly contributions of eminent figures like Robert J. Shiller, the authors synthesize insights from psychology and neurobiology, unraveling the manipulative essence inherent in narration. In the theoretical section, the article also references Uri Hasson's theories and research on brain synchronization during the communication process. The practical segment of the article substantiates these claims through the presentation of findings from neuropsychological studies. The study confirms the hypothesis that narratives infused with high sentiment resulting from emotional interactions, following a cause-and-effect structure with a visible beginning, development, and end, lead to better synchronization and intensify neuronal responses. The structure, plot shaping, and sentiment in messages, influenced by word choice, shape narrative economy and impact cognitive costs in decision-making. The obtained results confirm that precisely tailored narration effectively reduces cognitive costs associated with the decision-making process. This validates the authors' hypothesis, opening up space for research replication and falsification of the results obtained.","PeriodicalId":55690,"journal":{"name":"Oeconomica Jadertina","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139008050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
