Comparative Assessment of Linear and Nonlinear Analysis: Balıkesir Clock Tower Case Study
No full textHistorical masonry clock towers represent a significant component of the cultural heritage, having been subjected to a range of environmental and seismic influences throughout their existence. However, due to material ageing, structural features and deterioration over time, they are quite vulnerable to earthquakes. Consequently, there is a necessity to comprehensively understand the seismic behaviour of such structures in order to ensure their effective protection and strengthening. In this study, the seismic behaviour of the historical Balıkesir Clock Tower was investigated. In order to evaluate the dynamic behaviour of the clock tower, modal analysis and linear and nonlinear time history analyses were performed. As a result of the analyses, the behaviour of the clock tower as a result of linear and non-linear time history analyses was compared. As a result of the time history analyses, it was found that the results of the linear and non-linear time history analyses showed significant differences. Although the displacement and stress contours obtained as a result of the analyses were similar, the resulting displacement and stress values were quite different. The results obtained make a significant contribution to the ability to carry out more reliable analyses of the seismic behaviour of historic masonry structures
UTJECAJ SOCIODEMOGRAFSKIH ČIMBENIKA, MENTALNOG ZDRAVLJA I RAVNOTEŽE IZMEĐU POSLOVNOG I PRIVATNOG ŽIVOTA NA PODUZETNIČKE NAMJERE: MODERIRAJUĆA ULOGA STRAHA OD NEUSPJEHA
No full textIn recent years, mental health and work–life balance has emerged as important themes in entrepreneurship research. Their influence on individuals’ entrepreneurial intentions, particularly among healthcare professionals, has received limited scholarly attention. The purpose of this study is to examine the impact of mental health and work–life balance on the entrepreneurial intentions of health professionals, and to examine the moderating role of fear of failure within this relationship and socio-demographic factors. A cross-sectional survey was conducted with a sample of 552 healthcare professionals in Kosovo. The findings show that individuals who report better mental health and stronger work–life balance have higher entrepreneurial intentions. Findings also show that individuals who reported no fear of failure have higher entrepreneurial intentions. Furthermore, fear of failure plays a moderating role in the relationship between work-life balance and entrepreneurial intentions, but not in the relationship between mental health and entrepreneurial intentions. In addition, the results suggest that individuals with higher income levels and greater work experience are less likely to pursue entrepreneurial careers. This study contributes to the growing body of literature emphasizing the importance of psychological factors when examining entrepreneurial intentions and highlights the need for further research with regards to these factors while taking into consideration institutional and cultural settings.Posljednjih godina mentalno zdravlje i ravnoteža između poslovnog i privatnog života pojavili su se kao važne teme u istraživanju poduzetništva. Njihov utjecaj na poduzetničke namjere pojedinaca, posebno među zdravstvenim radnicima, još uvijek nije znanstveno istražen. Svrha je ovog istraživanja ispitati utjecaj mentalnog zdravlja i ravnoteže između poslovnog i privatnog života na poduzetničke namjere zdravstvenih djelatnika, kao i moderirajuću ulogu straha od neuspjeha unutar tog odnosa i sociodemografskih čimbenika. Provedeno je prosječno istraživanje na uzorku od 552 zdravstvena radnika na Kosovu. Nalazi pokazuju da pojedinci koji prijavljuju bolje mentalno zdravlje i bolju ravnotežu između poslovnog i privatnog života imaju veće poduzetničke namjere. Nalazi također pokazuju da pojedinci koji su izjavili da se ne boje neuspjeha imaju veće poduzetničke namjere. Strah od neuspjeha igra moderirajuću ulogu u odnosu između ravnoteže između posla i privatnog života te poduzetničkih namjera, ali ne i u odnosu između mentalnog zdravlja i poduzetničkih namjera. Rezultati sugeriraju da je manja vjerojatnost da će pojedinci s višim primanjima i većim radnim iskustvom nastaviti poduzetničku karijeru. Ovo istraživanje pridonosi sve većem broju literature koja naglašava važnost psiholoških čimbenika pri ispitivanju poduzetničkih namjera te potrebu za daljnjim istraživanjem u vezi s tim čimbenicima, uzimajući u obzir institucionalno i kulturološko okruženje
Evaluation of greater wax moth (Galleria mellonella) larvae as an alternate host to study the virulence of Vibrio harveyi
No full textThis study evaluated the suitability of Galleria mellonella larvae as an alternative model for investigating the virulence of Vibrio harveyi, a significant fish pathogen in marine aquaculture. Traditional vertebrate models for studying aquatic pathogens are costly, raise ethical concerns, and are subject to regulatory restrictions. In contrast, G. mellonella larvae offer advantages such as low cost, minimal infrastructure requirements, rapid infection cycles, and greater ethical acceptability. Larvae were injected with V. harveyi suspensions, supernatants, or heat-killed bacteria, and survival rates were monitored. No mortality was observed in control groups or larvae injected with heat-killed bacteria, confirming that viable bacteria are necessary for pathogenic effects. Survival rates of larvae inoculated with bacterial supernatants at cfu/mL were strain-dependent but relatively high, with a range of at 168 h. The strain FR-5 exhibited no apparent pathogenicity in larvae. These findings suggest that G. mellonella may not be a reliable alternate host for studying V. harveyi infections, underlining the need to validate the suitability of alternate hosts in the study of the virulence of specific pathogenic species
Uvid u narav “meke” oikofobije
No full textIn this paper the author discusses the concept of oikophobia as defined by the
English philosopher Sir Roger Scruton. The primary aim of the paper is to demonstrate
that one may justifiably differentiate two kinds of oikophobia, which are
referred to in the paper as “hard” and “soft” oikophobia. There is a special emphasis
on proving the latter to be a valid construct. The distinction is proposed by
examining Scruton’s original notions of oikophobia and oikophilia through the
lens of Max Scheler’s phenomenology of love and hate. In addition, several other
authors who have written on phenomena meaningfully related to oikophobia in
the West are discussed in a comparative manner so as to provide the means for
further nuancing of the primary concept of oikophobia. Finally, as an example
of “soft” oikophobia, the author has taken the current issue of the Kosinj Valley
in Croatia.U ovom radu autor obrađuje koncept oikofobije kako ga je definirao engleski filozof
Roger Scruton. Primarni je cilj rada pokazati da je moguće opravdano razlikovati
dvije vrste oikofobije, o kojima se u radu govori kao “tvrdoj” i “mekoj” oikofobiji.
Pritom je cilj bio dokazati da je potonja valjan konstrukt. Distinkcija je predložena
kao rezultat istraživanja Scrutonovih izvornih pojmova oikofobije i oikofilije kroz
prizmu fenomenologije ljubavi i mržnje Maxa Schelera. Pored toga, u radu je komparativno
razmatran niz autora koji su pisali o pojavama značenjski povezanima
s oikofobijom na Zapadu, kako bi bila pružena potpora za preciznije nijansiranje
primarnoga koncepta oikofobije. Konačno, autor u radu raspravlja o aktualnom
slučaju Kosinjske doline u Hrvatskoj kao primjeru “meke” oikofobije
ŠTO POTIČE PODUZETNIČKU BUDNOST U VISOKOM OBRAZOVANJU: MEĐUODNOS SAMOUČINKOVITOSTI I FINANCIJSKE PISMENOSTI
No full textThis paper explores the psychological and financial factors that drive entrepreneurial alertness among university students, focusing on the roles of self-efficacy, subjective financial literacy and objective financial literacy. The study was conducted on a sample of 285 students from the University of Split in Croatia and the University of Mostar in Bosnia and Herzegovina. The analysis was performed using hierarchical regression and mediation techniques using the PROCESS macro in the SPSS. Findings indicate distinct influence between objective and subjective financial literacy on entrepreneurial alertness. While subjective financial literacy positively and significantly influences entrepreneurial alertness, objective financial literacy does not exert a direct effect. Instead, objective financial literacy indirectly influences entrepreneurial alertness through subjective financial literacy. This indicates that financial knowledge alone is not enough; it must be accompanied by confidence in one’s financial abilities to effectively drive entrepreneurial alertness. Self-efficacy emerged as key driver (predictor) as well as a mediator in this relationship. Students who believe in their competences and skills, who perceive that their efforts can impact their environment and future outcomes, have a stronger sense of self-efficacy and tend to be more motivated to identify entrepreneurial opportunities in their surroundings. These findings highlight the role of self-efficacy as a driver of entrepreneurial alertness among students. The results suggest that educational programs aimed at enhancing entrepreneurial potential should focus more on building students’ confidence and perceived abilities rather than solely improving financial knowledge. A more psychologically informed approach to entrepreneurial education could better prepare young individuals for engaging in entrepreneurial activities. Overall, this study contributes to the better understanding of the cognitive processes that effectively stimulate entrepreneurial alertness and provide guidelines for designing more effective educational interventions.Ovaj rad istražuje psihološke i financijske čimbenike koji potiču poduzetničku budnost među sveučilišnim studentima, s posebnim naglaskom na ulogu samoučinkovitosti, subjektivne financijske pismenosti i objektivne financijske pismenosti. Istraživanje je provedeno na uzorku od 285 studenata Sveučilišta u Splitu u Hrvatskoj i Sveučilišta u Mostaru u Bosni i Hercegovini. Analiza je provedena primjenom hijerarhijske regresije i medijacijskih tehnika, korištenjem makronaredbom PROCESS u programu SPSS. Nalazi ukazuju na različit utjecaj objektivne i subjektivne financijske pismenosti na poduzetničku budnost. Dok subjektivna financijska pismenost pozitivno i značajno utječe na poduzetničku budnost, objektivna financijska pismenost ne pokazuje izravan učinak. Umjesto toga, objektivna financijska pismenost neizravno utječe na poduzetničku budnost na temelju subjektivne financijske pismenosti. To upućuje na to da samo financijsko znanje nije dovoljno; potrebno ga je dopuniti samopouzdanjem u vlastite financijske sposobnosti za učinkovito poticanje poduzetničke budnosti. Samoučinkovitost se pojavila kao ključni pokretač (prediktor) i posrednik u ovom odnosu. Studenti koji vjeruju u svoje kompetencije i vještine, koji percipiraju da njihov napor može utjecati na okolinu i buduće ishode, imaju izraženiji osjećaj samoučinkovitosti i skloniji su motiviranije prepoznavati poduzetničke prilike u svojoj okolini. Ovi nalazi naglašavaju ulogu samoučinkovitosti kao pokretača poduzetničke budnosti među studentima. Rezultati upućuju na to da bi se obrazovni programi usmjereni na poticanje poduzetničkog potencijala trebali više fokusirati na izgradnju studentskog samopouzdanja i percipiranih sposobnosti, a ne isključivo na poboljšanje financijskog znanja. Psihološki utemeljen pristup poduzetničkom obrazovanju mogao bi bolje pripremiti mlade pojedince za bavljenje poduzetničkim aktivnostima. Općenito, ovo istraživanje doprinosi boljem razumijevanju kognitivnih procesa koji učinkovito potiču poduzetničku budnost i pružaju smjernice za osmišljavanje učinkovitijih obrazovnih intervencija
Kinetičko modeliranje rasta Mucor circinelloides na agaru od obranog mlijeka pri uvjetima temperature i aktiviteta vode relevantnim za mliječnu industriju
No full textThis study investigated the surface growth kinetics of Mucor circinelloides strain 1L cultivated on skim milk agar (SMA) under various temperature and water activity (aw) conditions, with relevance to dairy product spoilage prediction. Growth curves fitted using the Baranyi model exhibited high smoothness and reproducibility (R²>0.978; RMSE = 2.36±1.08 mm). Primary growth parameters, including lag phase duration and surface growth rate (sgr), were quantified across triplicate experiments and modelled using Ratkowsky and cardinal frameworks, respectively. Secondary modelling revealed environmental dependencies, with optimal sgropt at 33 mm/d and estimated cardinal parameters (Topt ≈ 32 °C, theoretical aw min = 0.97). Validation experiments simulating ewe lump cheese fermentation conditions demonstrated high predictive accuracy (R² = 0.989), with bias and accuracy factors confirming model reliability despite minor underestimations. Predicted visibility times (t3, colony diameter ≥ 3 mm) indicated rapid colonisation under favourable conditions, while combinations of reduced temperature (0,978; RMSE = 2,36±1,08 mm). Primarni parametri rasta, uključujući trajanje faze zastoja i površinsku brzinu rasta (sgr), kvantificirani su u triplikatu i modelirani pomoću Ratkowskyjeva i kardinalnog pristupa. Sekundarno modeliranje otkrilo je ovisnost o okolišnim uvjetima, s optimalnom površinskom brzinom rasta (sgropt) od 33 mm/dan te procijenjenim kardinalnim parametrima (Topt ≈ 32 °C; teoretski aw min = 0,97). Validacijski pokusi koji su simulirali uvjete fermentacije ovčjeg grudastog sira pokazali su visoku prediktivnu točnost (R² = 0,989), pri čemu su faktori pristranosti i preciznosti potvrdili pouzdanost modela unatoč neznatno manjim vrijednostima. Predviđena vremena vidljivosti (t3, promjer kolonije ≥ 3 mm) ukazala su na brzo koloniziranje u povoljnim uvjetima, dok su kombinacije sniženih temperatura (< 10 °C) i niskog aktiviteta vode (< 0,975) znatno produljile t3 iznad 30 dana. Ovi rezultati naglašavaju vrijednost kinetičkog modeliranja za procjenu rizika od gljivičnog kvarenja te potrebu za strogim higijenskim mjerama u sustavima proizvodnje mliječnih proizvoda
Numerical Analysis of Shear Force for Oblique Edge Die-Cutting Shear Utilizing ANSYS LS-DYNA
No full textThis paper presents the development of an advanced finite element model for pre-dicting shear forces during the oblique-edge punching of Q235B steel, a material widely used in industrial applications. The model, developed in AN-SYS/LS-DYNA, investigates the influence of key parameters such as shear edge in-clination, strip thickness, punching depth, and lateral clearance. Results indicate that peak shear forces decrease significantly as the shear edge inclination increas-es from 4.0° to 4.8°. Furthermore, the optimal lateral clearance is found to be be-tween 0.2 mm and 0.4 mm, leading to improved tool performance and material integrity. Model validation shows an error range of 8.47 % to 10.87 %, confirming its accuracy and practical applicability. This study offers valuable insights for op-timizing tool design and enhancing punching efficiency in industrial settings, particularly in cold rolling mills. Future work will extend the model to a broader range of materials, incorporate advanced tool geometries, and account for thermal effects, thereby deepening the understanding of the shearing process and enabling further improvements in tool performance
Game on: Exploring Hedonic Behavior, Social Influence, and Gamification Adoption in Tourism Through TAM
No full textThe application of gamification has become a transformative innovation in the tourism industry. This
study explores how gamification influences tourists' attitudes and behavioural intentions, highlighting
its role in driving technology adoption in the tourism sector by integrating the Technology Acceptance
Model (TAM) and examining the determinants of gamification adoption, emphasising hedonic behaviour
and social influence as primary motivators. Data were gathered from 418 respondents using purposive
sampling through a face-to-face, structured survey administered to tourists in Gembu, Nigeria, across
various demographic groups. The TAM served as the theoretical framework, while Covariance-Based
Structural Equation Modelling (CB-SEM) was used to analyse data to evaluate the links among hedonic
behaviour, social impact, and the adoption of gamification technology. The findings indicate that social
influence has a substantial and positive effect on the adoption of gamification and further demonstrate
that hedonic behavior is substantially associated with the utility of use. Attitude towards adoption exerted
the most substantial influence on intention to use. These findings validate the need to integrate external
factors, such as hedonic behaviour and social impact, into the TAM framework to better understand
gamification adoption in tourism. The paper addresses potential research directions and constraints for
future work. Based on the findings, the study authors recommend that tourism managers and destination
marketers integrate social interaction and user enjoyment elements into gamified applications to enhance
tourist engagement and technology adoption
