Sustainability Reporting and International Rankings in Higher Education : A Case of the University of Split, Croatia
No full textWe offer practical, case-based experiences on sustainability reporting in higher education institutions (HEIs), with a focus on the integration of sustainability activities into strategic planning and quality management. A proposed approach is based on the experience of the University of Split, Croatia, and the lessons learned from the SEA-EU University Alliance. In line with the Sustainable Development Goals (SDGs), our model emphasizes the active engagement of stakeholders and the continuous collection and review of sustainability data. In addition, we propose to automate the collection and dissemination of sustainability research findings through the implementation of a Current Research Information System (CRIS). Our case study provides a roadmap for improving sustainability performance and reporting. The experience of the University of Split (Croatia) could be helpful and generalizable to a number of universities with an intermediate level of maturity in sustainability management and reporting, trying to improve their university rankings
Croatian firefighters barrier to volunteering
No full textCilj: Cilj rada je ispitati koje od dvanaest ponuđenih prepreka dobrovoljni vatrogasci u Republici Hrvatskoj smatraju najozbiljnijima.
Metode: Ova anketa provedena je među 379 ispitanika od ukupne populacije 32.544, ispitanici su bili dobrovoljni vatrogasci iz urbanih, ruralnih i polururalnih područja Republike Hrvatske. Online upitnik odnosno anketa koja je provedena u ovom istraživanju sastojala se od šest dijelova: demografska obilježja ispitanika, prepreke za volontiranje, stavovi i zadovoljstvo, sukob privatnog života i dobrovoljnog rada, ponašanja i namjere vezano za odsustvo i namjera napuštanja službe. Uvodni dio odnosio se na demografiju ispitanika sa šest pitanja, u dijelu prepreke volontiranju ponuđeno je dvanaest prepreka, u dijelu zadovoljstvo volontiranjem ispitanicima je ponuđeno šest odgovora vezanih za njihove stavove i zadovoljstvo dobrovoljnim radom, dio koji se odnosi na sukob ponudio je sedam mogućnosti sukoba privatnog života s dobrovoljnim radom, u dijelu koji se odnosi na izostanak i odsustvo s osposobljavanja i vježbi ponuđena su dva odgovora a u posljednjem dijelu ponuđeno je pet mogućnosti napuštanja vatrogasne službe.
Rezultati: Dobrovoljni vatrogasci po pitanju sukoba privatnog života uglavnom se ne slažu da ih vatrogasne aktivnosti odvajaju od privatnih aktivnosti te da moraju propustiti obiteljske aktivnosti ili druženje s prijateljima zbog obveza u vatrogasnoj postrojbi. Također uglavnom se ne slažu da ih vatrogasne aktivnosti fizički ili emocionalno sprječavaju u obiteljskim obvezama ili dužnostima. Ne smatraju da postoji ikakav stres uzrokovan vatrogasnim aktivnostima koji bi ih spriječio u obavljanju stvari u kojima uživaju. Uglavnom se ne slažu da često izostaju s obuka i vježbi, a uopće se ne slažu da često razmišljaju o izostanku s obuka i vježbi. Vrlo rijetko razmišljaju o odustajanju od svoje dobrovoljne vatrogasne službe i ne pokazuju nikakav interes za napuštanje službe. Prepreku sukob posao/škola 80,74 % ispitanika ocijenilo je kao najznačajniju prepreku. Provedenim ANOVA testom usporedbe prepreka koje su ocijenile žene i muškarci utvrđena je vrijednost P˂0,001 što upućuje n to da postoji statistički značajna razlika između srednjih vrijednosti skupina, ovdje je također utvrđeno da su sve ispitanice ocijenile financijske razloge, sukob s vodstvom, nedostatak zanimljivih aktivnosti i poteškoće s prijevozom za najozbiljnije prepreke dok su muškarci kao najozbiljniju prepreku ocijenili sukob 31 posao/škola. Usporedbom prepreka utvrđenih na dobrovoljnim vatrogascima iz RH i Finskim vatrogascima prema ANOVA testu utvrđena je vrijednost P 0,006 što upućuje na to da postoji statistički značajna razlika između srednjih vrijednosti skupina vatrogasaca iz RH i Finske (Malinen i sur, 2018). Najozbiljnija prepreka utvrđena u ova dva istraživanja također se razlikovala, i to tako da su dobrovoljni vatrogasci iz RH za najozbiljniju prepreku ocijenili sukob posao/škola, dok je nedostatak vremena ocijenjen kao najozbiljnija prepreka kod dobrovoljnih vatrogasaca u Finskoj (Malinen i sur, 2018).
Zaključci: Istraživanje je pokazalo da je najozbiljnija prepreka za volontiranje vatrogasaca u RH sukob posao/škola čime nije potvrđena postavljena hipoteze kako je najznačajnija prepreka ostale poteškoće vezane uz posao. Druga i treća utvrđena prepreka su nedostatak vremena i ostale poteškoće vezane uz posao čime nije potvrđena postavljena hipoteze kako je jedna od tri najozbiljnije prepreke nedostatak financijskih sredstava. Ova hipoteza potvrđena je samo u dijelu uzorka u kojem su ispitanici žene. Istraživanje je potvrdilo da dobrovoljni vatrogasci u RH ne pokazuju interes za napuštanje vatrogasne službe. Istraživanje je pokazalo da postoji značajna razlika u percepciji prepreka dobrovoljnih vatrogasaca u Republici Hrvatskoj u odnosu na prepreke s kojima se susreću dobrovoljni vatrogasci u Finskoj (Malinen i sur, 2018).Objective: The objective of the paper is to examine which of the twelve offered obstacles volunteer firefighters in the Republic of Croatia consider to be the most serious.
Methods: This survey was conducted among 379 respondents out of a total population of 32,544, the respondents were volunteer firefighters from urban, rural and semi-rural areas of the Republic of Croatia. The online questionnaire or survey that was conducted in this research consisted of six parts: demographic characteristics of respondents, obstacles to volunteering, attitudes and satisfaction, conflict between private life and voluntary work, behavior and intentions related to absence and intention to leave the service. The introductory part referred to the respondents' demographics with six questions, in the section on obstacles to volunteering, twelve obstacles were offered, in the section on satisfaction with volunteering, the respondents were offered six answers related to their attitudes and satisfaction with voluntary work, the section related to conflict offered seven possibilities of private conflict life with voluntary work, in the part that refers to absence from training and exercises, two answers were offered, and in the last part, five options for leaving the fire service were offered.
Results: Regarding personal life conflicts, volunteer firefighters mostly disagree that firefighting activities separate them from their private activities and that they have to miss family activities or spending time with friends due to obligations in the fire department. They also generally disagree that firefighting activities physically or emotionally prevent them from family obligations or duties. They do not feel that there is any stress caused by firefighting activities that would prevent them from doing the things they enjoy. They generally do not agree that they often miss training and exercises, and they do not agree at all that they often think about missing training and exercises. They very rarely consider giving up their volunteer fire service and show no interest in leaving the service. 80.74% of respondents rated the obstacle of work/school conflict as the most significant obstacle. The conducted ANOVA test comparing the obstacles evaluated by women and men revealed a value of P˂0.001, which indicates that there is a statistically significant difference between the mean values of the groups, here it was also determined that all womwn respondents evaluated financial reasons, conflict with management, lack of interesting activities and difficulties with transportation as the most serious obstacle, while men rated the work/school conflict as the most serious obstacle. By comparing the obstacles determined on volunteer firefighters from the Republic of Croatia and Finnish firefighters according to the ANOVA test, a P value of 0.006 was determined, which indicates that there is a statistically significant difference between the mean values of the groups 33 of firefighters from the Republic of Croatia and Finland (Malinen et al, 2018). The most serious obstacle identified in these two studies also differed, so the volunteer firefighters from the Republic of Croatia rated the conflict between work and school as the most serious obstacle, while lack of time was rated as the most serious obstacle among volunteer firefighters in Finland (Malinen et al, 2018).
Conclusions: The research showed that the most serious obstacles for volunteering firefighters in the Republic of Croatia is the work/school conflict, which did not confirm the hypothesis that the most significant obstacle is other work-related difficulties. The second and third identified obstacles are lack of time and other difficulties related to work, which did not confirm the hypothesis that one of the three most serious obstacles is a lack of financial resources. This hypothesis was confirmed only in the part of the sample where the respondents were women. The survey confirmed that volunteer firefighters in the Republic of Croatia do not show interest in leaving the fire service. The research showed that there is a significant difference in the perception of obstacles by volunteer firefighters in the Republic of Croatia compared to the obstacles faced by volunteer firefighters in Finland (Malinen et al, 2018)
Special evidentiary actions in the Croatian criminal legislation
No full textDiplomski rad istražuje problematiku posebnih dokaznih radnji unutar hrvatskog kaznenog postupka. Sukus rada je na pretpostavkama za poduzimanje i modalitetima provedbe pojedine posebne dokazne radnje s naglaskom na supsidijarnost njihove primjene i poštovanje načela razmjernosti. Analizirane su materijalne pretpostavke za poduzimanje posebnih dokaznih radnji, napose postojanje osnova sumnje, katalog kaznenih djela za koja je posebne dokazne radnje moguće naložiti te dokaze poteškoća za provođenje izvida koje opravdavaju njihovu primjenu (načelo razmjernosti). Detaljno su analizirane i kritički preispitane formalne pretpostavke s posebnim naglaskom na zahtjev državnog odvjetnika te pisani i obrazloženi naloga suca istrage. U kontekstu formalnih pretpostavki analizirane su i odredbe koje se odnose na vremensko ograničenje njihove primjene. Obrazložene su uloge tijela koja sudjeluju u procesu ishođenja naloga za provođenje posebnih dokaznih radnji, a napose je opisan trokut suradnje između državnog odvjetnika koji zahtjeva izdavanje naloga za određivanje posebnih dokaznih radnji, policije koja provodi posebne dokazne radnje i suca istrage koji ih nalaže te provodi sudsku kontrolu nad njihovim provođenjem. Jezgrovito je pristupljeno sistematičnoj obradi načina poduzimanja pojedinih posebnih dokaznih radnji, dotičući se pri tome specifičnosti koje se pojavljuju kod svake pojedine radnje. Kroz praktičan primjer iz prakse dočarane su poteškoće u pogledu očuvanju tajnosti mjera, jer zbog specifičnosti ustroja organizacija koje sudjeluju u provođenju mjera, veliki broj službenika unutar represivnog sustava biva upoznat s podacima koji bi trebali biti tajni.
Ciljevi ovog rada su pobliže pojasniti institut posebnih dokaznih radnji kroz analizu njihovih uvjeta primjene i načina provođenja. Rad naglašava važnost posebnih dokaznih radnji kao neophodnog alata suvremenog kaznenog pravosuđa koji može značajno doprinijeti otkrivanju i progonu počinitelja teških kaznenih djela koja nerijetko karakterizira konspirativnost i tajnost djelovanja.The diploma thesis investigates the issue of special evidentiary actions within the Croatian criminal procedure. The context of the work is based on the assumption for undertaking and the modalities of implementation of each special evidentiary action with an emphasis on the subsidiarity of their application and respect for the principle of proportionality. The material assumptions and the undertaking of special evidentiary actions were analyzed, especially the grounds for suspicion, the catalog of criminal offenses for which special evidentiary actions can be ordered, and the evidentiary difficulties for conducting investigations that justify their application (principle of proportionality). The formal assumptions were analyzed in detail and critically reviewed, with special emphasis on the state attorney's request and the investigative judge's written and explained orders. In the context of formal assumptions, the provisions related to the time limit of their application were also analyzed. The roles of the bodies participating in the process of obtaining orders for the implementation of special evidentiary actions are explained. In particular, the triangle of cooperation between the state attorney who requests the issuance of an order for the determination of special evidentiary actions, the police, who conducts special evidentiary actions, and the investigating judge, who orders them and carries out the judicial control over their implementation, is described. A systematic treatment of the way of undertaking individual special evidentiary actions was succinctly approached while touching on the specifics that appear in each individual action. Through a practical example from practice, the difficulties in preserving the secrecy of the measures are illustrated, because due to the specificity of the structure of the organizations participating in the implementation of the measures, a large number of officials within the repressive system become familiar with information that should be secret.
The goals of this paper are not just to explain the institute of special evidentiary actions, but to provide a practical understanding of their conditions of application and methods of implementation. The paper emphasizes the importance of special evidentiary actions as a necessary tool of modern criminal justice that can significantly contribute to the detection and prosecution of perpetrators of serious crimes, which are often characterized by conspiratorial and secret actions
Analysis of characteristics of mobbing - abuse in the workplace
No full textAnaliza značajki mobinga – zlostavljanja na radnom mjestu dubinski istražuje fenomen mobinga kao složenog oblika nasilničkog ponašanja koje se manifestira kroz različite oblike agresije, poput verbalnog zlostavljanja, socijalne isključenosti, prijetnji i korištenja moći za uznemiravanje pojedinca ili grupe. Ovo sitraživanje naglašava kako mobing ima duboke korijene u organizacijskoj kulturi i kako se može negativno odraziti ne samo na pojedinca koji je žrtva, već i na opću produktivnost, moral i radnu atmosferu organizacije. Pokazalo se da su posljedice mobinga višestruke i ozbiljne, uključujući emocionalni i fizički stres, anksioznost, depresiju i izgaranje kod žrtava. Analiza dalje razmatra kako individualne osobine i organizacijski čimbenici, poput stresa vezanog uz posao i loše komunikacije,doprinose nastanku i perpetuiranju mobinga. Studija također ističe važnost sveobuhvatnog pristupa u rješavanju problema mobinga, koji uključuje razvoj politika i postupaka za prevenciju, kao i pružanje podrške i zaštite žrtvama. Posebno se naglašava uloga pravnog okvira i institucionalne podrške u zaštiti prava žrtava na radnom mjestu. Kroz analizu je postalo jasno da su suradnja, edukacija i promjena organizacijske kulture ključni elementi u borbi protiv mobinga. U zaključku, studija poziva na zajedničke napore zaposlenika, menadžera i društva u cjelini kako bi se stvorilo zdravije i sigurnije radno okruženje koje promiče rast, razvoj i dobrobit svih članova osoblja.The analysis of the features of mobbing - abuse in the workplace deeply investigates the phenomenon of mobbing as a complex form of violent behavior that manifests itself through various forms of aggression, such as verbal abuse, social exclusion, threats and the use of power to harass an individual or group. This research highlights how mobbing has deep roots in organizational culture and how it can have a negative impact not only on the individual who is the victim, but also on the general productivity, morale and working atmosphere of the organization. The consequences of mobbing have been shown to be multiple and serious, including emotional and physical stress, anxiety, depression and burnout in victims. The analysis further considers how individual characteristics and organizational factors, such as work-related stress and poor communication, contribute to the emergence and perpetuation of mobbing. The study also highlights the importance of a comprehensive approach to solving the problem of mobbing, which includes the development of policies and procedures for prevention, as well as providing support and protection to victims. The role of the legal framework and institutional support in protecting the rights of victims in the workplace is particularly emphasized. Through the analysis, it became clear that cooperation, education and
change of organizational culture are key elements in the fight against mobbing. In conclusion, the study calls for joint efforts by employees, managers and society as a whole to create a healthier and safer work environment that promotes the growth, development and well-being of all staff members
Young people's perception of safety on social networks
No full textDruštvene mreže postale su dio naše svakodnevnice. Sredstvo su komunikacije i društvene
interakcije, a nerijetko i posao. Pronašle su svoje korisnike širom svijeta među mnogim
generacijama, a pogotovo među mladim ljudima. Cilj ovog rada bio je istražiti u kojoj
mjeri mladi koriste društvene mreže, koriste li ih na ispravan način i jesu li svjesni
opasnosti na koje mogu naići prilikom korištenja istih. U svrhu istraživanja percepcije
sigurnosti na društvenim mrežama kod mladih osoba provela se anketa među 219 osoba
oba spola, starosti između 18 i 30 godina.
Rezultati istraživanja pokazali su kako mladi u Republici Hrvatskoj dobro poznaju
opasnosti kojima su izloženi na društvenim mrežama, ali su istovremeno nedovoljno
oprezni oko sigurnosti svojih podataka i lakovjerno pristupaju ponuđenim sadržajima. Pri
tomu ne postoji povezanost između vrste i razine obrazovanja, spola ili mjesta stanovanja
mladih i njihovih stavova o privatnosti, ponašanju, percepciji sigurnosti te lažnim
vijestima na društvenim mrežama.
Ipak, rezultati istraživanja pokazuju kako mladi, uz iznimku izloženosti lažnim vijestima,
nisu u velikoj mjeri žrtve kaznenih djela preko društvenih mreža. Oni mladi koji su ipak
bili žrtve, nakon neželjenih događaja postaju puno oprezniji po pitanju vlastite sigurnosti i
zaštite osobnih podataka na društvenim mrežama.Social networks have become a part of everyday life. They are often a job as well as
means of communication and social interactions. They have found their users across the
globe among many generations, especially among young people. The aim of this paper is
to determine how the young population uses social networks, if they use it properly and if
they are aware of possible dangers the networks carry. For the purpose of this research a
survey has conducted among 219 people of both genders, between the ages 18 and 30.
The results have shown that young in the Republic of Croatia are well aware of the
dangers of using the social networks. At the same time, the young are also not careful
enough about the safety of their dana while they also access various content naively.
There is no connection between the type of education, level of education, gender or
residence and their views on privacy, behaviour, safety perception and fake news.
However, the results show that young, although being exposed to fake news, are not
usually victims of felonies committed via social networks. The ones who experienced
online frauds or crimes have become much more careful about their personal safety as
well as the account and personal data protection
The relationship between financial manipulations and gender of independent auditor
No full textSmanjenje povjerenja u revizorske usluge uslijed velikih korporativnih skandala rezultiralo je povećanim interesom korisnika financijskih izvještaja za procjenu kvalitete eksterne revizije. U tom kontekstu, znanstvena istraživanja analizirala su brojne varijable, a jedna od njih je spol revizora. S obzirom na to da rezultati dosadašnjih znanstvenih istraživanja upućuju na postojanje poželjnih karakteristika kod revizorica u usporedbi s njihovim muškim kolegama, temeljni ciljevi ovog istraživanja podrazumijevali su ispitivanje povezanosti spola neovisnog revizora s razinom manipulacija u financijskim izvještajima, kao i stjecanje uvida u različite karakteristike provedenih revizija poput spola glavnog revizijskog partnera, veličine revizorskih društava, rotacije revizorskih društava i glavnih revizijskih partnera, mišljenja neovisnog revizora i broja ključnih revizijskih pitanja istaknutih u izvješćima neovisnih revizora. Razina manipulacija u financijskim izvještajima procijenjena je s pomoću Jones modela. Uzorkom istraživanja obuhvaćena su trgovačka društva koja su kotirala na Zagrebačkoj burzi u razdoblju od 2012. do 2021. Prilikom utvrđivanja povezanosti manipulacija u financijskim izvještajima i spola neovisnog revizora korištene su statističke metode poput deskriptivne analize, korelacijske analize i regresijske analize. Rezultati upućuju na nepostojanje povezanosti manipulacija u financijskim izvještajima i spola neovisnog revizora u Republici Hrvatskoj.The decrease in trust in audit services due to major corporate scandals has resulted in an increased interest of users of financial statements in assessing the quality of external audits. In this context, scientific research has analyzed numerous variables, one of which is the gender of the auditor. Given that the results of previous scientific research indicate the existence of desirable characteristics in female auditors compared to their male colleagues, the basic goals of this research included examining the connection between the gender of the independent auditor and the level of manipulation in financial statements, as well as gaining insight into the different characteristics of audits, such as the gender of the lead audit partner, the size of the audit firms, the rotation of audit firms and lead audit partners, the opinion of the independent auditor and the number of key audit matters highlighted in the reports of the independent auditors. The level of manipulations in financial statements was estimated using the Jones model. The research sample included trading companies that were listed on the Zagreb Stock Exchange in the period from 2012 to 2021. Statistical methods such as descriptive analysis, correlation analysis and regression analysis were used to determine the connection between manipulations in financial statements and the gender of the independent auditor. The results indicate that there is no connection between manipulations in financial statements and the gender of the independent auditor in the Republic of Croatia
Legal consequences of use of illegal substances by professional athletes
No full textKorištenje nedozvoljenih supstanci poznato je od kada je poznat i sam sport kao disciplina. Cilj
svakog sportskog natjecanja bio je i ostao biti bolji od drugih i postići što bolje rezultate. Iako
je to nekada bila stvar statusa i prestiža sada su stvari nešto drugačije. Popularnost sporta se već
dugi niz godina drži na vrhuncu i nagrade koje sa sobom nose sportski uspjesi nisu više samo
status i priznatost društva, već vrtoglave cifre. Takvim preokretom nagrade za sportsku
aktivnost došlo je do preokreta i u samim sportskim aktivnostima i nedozvoljenim supstancama
koje se pojavljuju u njemu. Imovinska korist postala je pogodno tlo za razvoj organizirane
mreže kriminala trgovine nedozvoljenim supstancama koje su igrači uzimali smatrajući je
niskim rizikom a veoma dobrim profitom. Tako su napredovale i same nedozvoljene supstance
od potpuno prirodnih, i donekle bezazlenih, do ozbiljnih kemijskih tvari koje znatno utječu na
zdravlje sportaša a u svojoj konačnici njihovo djelovanje može dovesti čak i do smrti. Ovakvim
pretvaranjem časnog sporta u nešto što je nečasno, zakon je morao reagirati. Zbog
sveprisutnosti i popularnost sporta u svakom kutku naše zemlje, nacionalna zakonodavstva se
nije imalo kada čekati da odrade svoje pa je borba protiv nedozvoljenih supstanci u sportu
krenula u nešto obrnutom smjeru. Prvenstveno se o njoj povelo računa na globalno j,
međunarodnoj razini. Uspostavljanjem propisa i pravila, i stvaranjem međunarodnih
instrumenata na toj razini, stvari su se silazno počele preslikavati na regionalnim a potom i
nacionalnim razinama i rezultati su bili zakoni kojima se nastojala, i još uvijek nastoji, smanjiti,
a na kraju i potpuno uništiti prisutnost ovakvog kriminalnog ponašanja u profesionalnom
sportu.The use of illegal substances has been known since the sport itself was known as a discipline.
The goal of every sports competition was and remains to be better than others and to achieve
the best possible results. Although it used to be a matter of status and prestige, now things are
somewhat different. The popularity of sports has been at its peak for many years, and the
rewards that come with sports successes are no longer just status and recognition of society, but
dizzying figures. With such a reversal of the prize for sports activity, there was a reversal in the
sports activities themselves and the illegal substances that appear in it. Financial gain became
a suitable ground for the development of an organized criminal network of trafficking in illegal
substances that players took, considering it a low risk and a very good profit. This is how the
illegal substances themselves progressed from completely natural, and somewhat harmless, to
serious chemical substances that significantly affect the health of athletes, and ultimately their
action can even lead to death. By turning an honorable sport into something dishonorable like
this, the law had to react. Due to the ubiquity and popularity of sports in every corner of our
country, there was no time to wait for the national legislation to do its job, so the fight against
illegal substances in sports went in a somewhat opposite direction. Primarily, it was taken into
account on a global, international level. With the establishment of regulations and rules, and
the creation of international instruments at that level, things began to be mirrored downwards
at the regional and then national levels, and the results were laws that sought, and still strive, to
reduce, and in the end completely destroy, the presence of such criminal behavior in
professional sports
Infuence of financial frauds on share price movements
No full textCilj ovog rada je ustanoviti kako optužbe za financijske prijevare utječu na cijene dionicakompanija, kako kratkoročno tako i dugoročno. Analiza se fokusira na reakcije tržišta odmah nakon objave optužbi i kroz trogodišnji period. Također, rad uspoređuje promjene cijena dionica pogođenih kompanija s relevantnim tržišnim indeksima kako bi se istražili opći tržišni trendovi. Istraživanje je obuhvatilo uzorak od 21 kompanije optužene za financijske prijevare. Podaci o kretanju cijena dionica i tržišnih indeksa prikupljeni su korištenjem Bloomberg Terminala i S&P Capital IQ platformi. Provedena je kvantitativna analiza promjena u cijenama dionica i indeksima kroz različite vremenske intervale – od prvog dana do tri godine nakon optužbi. Primijenjen je Studentov t-test i Wilcoxonov test za provjeru statističke značajnosti promjena cijena dionica. Kratkoročno, dionice optuženih kompanija bilježe značajan pad od prosječnih -10,53% prvog dana nakon optužbi, dok su tržišni indeksi ostali relativno stabilni (- 0,66%). Srednjoročno, unutar prve godine, dionice tih kompanija bilježe daljnji pad vrijednosti od -44,47%, dok su tržišni indeksi nastavili rasti. Dugoročno, nakon tri godine, dionice svih kompanija u uzorku zabilježile su prosječan pad od -74,69%, dok su indeksi zabilježili rast od 37,71%. Korelacija između cijena dionica optuženih kompanija i tržišnih indeksa opada kroz vrijeme, gotovo nestajući u dugoročnom razdoblju. Financijske prijevare uzrokuju značajan pad cijena dionica, što je potvrđeno kroz sva promatrana razdoblja. Tržišni indeksi pokazuju otpornost i rast kroz vrijeme, dok pogođene kompanije dugoročno gube povjerenje investitora i bilježe pad cijena. Rezultati istraživanja potvrđuju alternativnu hipotezu da financijske prijevare uzrokuju značajan pad cijene dionica kroz vrijeme.The aim of this paper is to determine how accusations of financial fraud affect the stock prices of companies, both in the short and long term. The analysis focuses on market reactions immediately after the accusations are made public and over a three-year period. The study also compares changes in the stock prices of affected companies with relevant market indices to investigate broader market trends. The research included a sample of 21 companies accused of financial fraud. Data on stock price movements and market indices were collected using Bloomberg Terminal and S&P Capital IQ platforms. Quantitative analysis of changes in stock prices and indices was conducted across different time intervals, from the first day to three years after the accusations. A Student’s t-test and Wilcoxon signed-rank test was applied to verify the statistical significance of stock price changes. In the short term, the accused companies' stocks experienced a significant decline of -10.53% on average on the first day after the accusations, while the market indices remained relatively stable -0.66%. In the mid-term, within the first year, these companies' stocks further declined by -44.47%, while market indices continued to rise. In the long term, after three years, the stocks of all companies in the sample recorded an average decline of -74.69%, while the indices showed a growth of 37.71%. The correlation between the stock prices of the accused companies and market indices decreased over time, almost disappearing in the long term. Financial fraud have a significant negative impact on stock prices, as confirmed in all observed periods. Market indices demonstrate resilience and growth over time, while the affected companies lose investor confidence and show a long-term decline in stock prices. The research results confirm the alternative hypothesis that financial fraud cause a significant decline in stock prices over time
Frequency and type of mutations in the EGFR gene in patohistological and cytological samples of lung carcinoma
No full textCilj: Utvrditi tip i učestalost pojedinih mutacija EGFR gena u slučajevima karcinoma pluća u razdoblju od 01. siječnja 2021. do 01. travnja 2023. godine u Kliničkoj bolnici Dubrava na Kliničkom zavodu za patologiju i citologiju.
Metode: Rezultati i podatci iz anamneze retrospektivno su prikupljeni iz laboratorijskog informacijskog sustava Issa na Kliničkom zavodu za patologiju i citologiju. Prikupljeni su podatci o dobi, spolu te rezultatima testiranja na EGFR mutaciju. Sekvenciranje epidermalnog receptora faktora rasta (EGFR) u Kliničkoj bolnici Dubrava izvodi se korištenjem Idylla™ EGFR mutacijskog testa na Biocartis Idylla™ RT-PCR sustavu iz uzoraka parafinskih blokova ili citoloških razmaza.
Rezultati: U promatranom razdoblju kod 251 pacijenta sa dijagnozom karcinoma pluća određeno je molekularno testiranje EGFR gena. Kod većine ispitanika (83,3%) uputna dijagnoza bio je adenokarcinom pluća. Testiranje je izvršeno na 140 citoloških (55,8%) te 111 patohistoloških uzoraka (44,2%). Mutacija je pronađena kod 57 (23%) uzoraka, i to češće kod žena (52,6%) u odnosu na muškarce (47,4%). Najčešće detektirane mutacije su točkasta mutacija L858R i delecija u egzonu 19. Kod testiranih žena, najviše je bilo slučajeva adenokarcinoma pluća s mutacijama L858R i delecijom u egzonu 19 u dobi od 61 do 70 godina. Kod testiranih muškaraca, također su najčešće mutacije bile L858R i delecija u egzonu 19, i to u dobi od 71 do 80 godina. Za 58,6% testiranih pacijenata prikupljeni su podatci o navikama konzumiranja cigareta te je vidljivo da većina pripada kategorijama pušača i bivših pušača (77%) što ukazuje na to da je pušenje značajan faktor rizika za razvoj i obolijevanje od karcinoma pluća.
Zaključci: Rezultati ove retrospektivne studije upućuju na važnost molekularnog testiranja EGFR gena u pacijenata sa dijagnosticiranim karcinomom pluća, kako bi što prije dobili ciljanu terapiju, te samim time poboljšali ishod liječenja. Nedostatak podataka o pušačkom statusu kod značajnog broja pacijenata naglašava potrebu za boljom dokumentacijom i praćenjem životnih navika koje mogu utjecati na razvoj karcinoma pluća.Aim: To determine the type and frequency of individual EGFR gene mutations in cases of lung cancer in the period from January 1, 2021 to April 1, 2023 at the Dubrava Clinical Hospital at the Clinical Institute of Pathology and Cytology.
Methods: Results and data from the anamnesis were collected retrospectively from the laboratory information system Issa at the Clinical Institute of Pathology and Cytology. Data on age, gender and the results of EGFR mutation testing were collected. Epidermal growth factor receptor (EGFR) sequencing at Dubrava Clinical Hospital is performed using the Idylla™ RT-PCR system from paraffin blocks or cytological smears.
Results: In the observed period, 251 patients diagnosed with lung cancer underwent molecular testing of the EGFR gene. In the majority of subjects (83,3%), the referring diagnosis was lung adenocarcinoma. Testing was performed on 140 cytological (55,8%) and 111 pathohistological samples (44,2%). Mutation was found in 57 (23%) samples, and this is more common in women (52,6%) compared to men (47,4%). The most frequently detected mutations are point mutation L858R and deletion in exon 19. In the tested women, there were more cases of lung adenocarcinoma with L858R and deletion in exon 19 between the ages of 61 and 70. In the tested men, the most frequent mutations were also L858R and deletion in exon 19, and this at the age of 71 to 80 years. Dana on cigarette comsumption habits were collected for 58,6% of tested patients, and it is evident that the majority belong to the categories of smokers and ex-smokers (77%), which indicates that smoking is a significant risk factor for developing and contracting lung cancer.
Conclusions: The results of this retrospektive study point the importance of molecular testing of the EGFR gene in patients diagnosed with lung cancer, in order to receive targeted therapy as soon as possible, thereby improving of the outcome of treatment. The lack of data of the smoking status of a significant number of patients higlights the need for better documantation and monitoring of lifestyle habits that may affect the development of lung cancer
