Comparative analysis of nonlinear models developed using machine learning algorithms
Maja Rožman, Alen Kišić, Dijana Oreški, 2024, original scientific article

Abstract: Machine learning algorithms are increasingly used in a vast spectrum of domains where statistical approaches were previously used. Algorithms such as artificial neural networks, classification, regression trees, or support vector machines provide various advantages over traditional linear regression or discriminant analysis. Advantages such as flexibility, scalability, and improved accuracy in dealing with diverse data types, nonlinear problems, and dimensionality reduction, compared to traditional statistical methods are empirically demonstrated in many previous research papers. In this paper, two machine learning algorithms are compared with one statistical method on highly nonlinear data. Results indicate a high level of effectiveness for machine learning algorithms when dealing with nonlinearity.
Keywords: machine learning, decision tree algorithm, artificial neural network, predictive models, data characteristics, nonlinear data, artificial intelligence

Exploring differences in green innovation among countries with individualistic and collectivist cultural orientations
Alona Sova, Maja Rožman, Romana Korez-Vide, 2024, original scientific article

Abstract: In this paper, we explore the extent to which individualistic and collectivist national cultural orientations are essential for green innovation. In this context, we also examine the extent of green innovation in countries at different levels of socioeconomic development. All data were collected for the latest available year (2020). This research was carried out on a sample of 60 selected countries, using parametric tests to identify statistically significant differences between variables and descriptive statistics to examine statistically significant differences in-depth. The results show that, on average, countries with prevailing individualistic cultural orientations and high levels of socioeconomic development perform better in green innovation than countries with prevailing collectivist cultural orientations. On average, countries with a prevailing individualistic cultural orientation scored moderate on green innovation, while countries with a prevailing collectivist orientation scored low. However, the level of socioeconomic development, including designing and implementing green policies, was recognized as essential to green innovation in both national cultures with prevailing individualistic orientations and national cultures with prevailing collectivist orientations.

Psychological factors impacting academic performance among business studies’ students
Maja Rožman, Igor Vrečko, Polona Tominc, 2025, original scientific article

Abstract: This study explores the significant psychological factors that impact academic success among students. The sample included 287 undergraduate and postgraduate students of business studies. Structural Equation Modeling was used to analyze the data, investigating the impact of students’ motivation, mental and physical health, work-life balance, and anxiety on both perceived academic success as well as quantitative indicators of academic success. The findings reveal that students’ motivation is significant for enhancing academic success. Additionally, while mental and physical health are significant contributors to academic success, balancing academic work with personal life is essential for fostering a positive perception of academic success. Conversely, anxiety, particularly exam-related, negatively affects students’ perceived academic success, highlighting the need for comprehensive support systems. These findings offer crucial insights for educators and policymakers, paving the way for innovative strategies that enhance academic success and empower students to thrive holistically, both academically and personally. By addressing the full spectrum of challenges students face, we can foster a more resilient, motivated, and successful generation of students.

Navigating gender nuances : assessing the impact of AI on employee engagement in Slovenian entrepreneurship
Maja Rožman, Polona Tominc, 2024, original scientific article

Abstract: Background: Our research delved into exploring various selected facets of AI-driven employee engagement, from the gender perspective, among Slovenian entrepreneurs. Methods: This research is based on a random sample of 326 large enterprises and SMEs in Slovenia, with an entrepreneur completing a questionnaire in each enterprise. Results: Findings suggest that there are no significant differences between male and female entrepreneurs in Slovenia regarding various aspects of AI-supported entrepreneurial management practice including the following: AI-supported entrepreneurial culture, AI-enhanced leadership, adopting AI to reduce employee workload, and incorporating AI tools into work processes. The widespread integration of AI into entrepreneurship marks a transition to a business landscape that values inclusivity and equity, measuring success through creativity, strategic technology deployment, and leadership qualities, rather than relying on gender-based advantages or limitations. Our research also focused on the identification of gender differences in path coefficients regarding the impact of the four previously mentioned aspects of AI on employee engagement. While both genders see the value in using AI to alleviate employee workload, the path coefficients indicate that female entrepreneurs report higher effectiveness in this area, suggesting differences in the implementation of AI-integrated strategies or tool selection. Male entrepreneurs, on the other hand, appear to integrate AI tools into their work processes more extensively, particularly in areas requiring predictive analytics and project scheduling. This suggests a more technical application of AI in their enterprises. Conclusions: These findings contribute to understanding gender-specific approaches to AI in enterprises and their subsequent effects on employee engagement.

Vpliv stresa na tiho odhajanje zaposlenih v organizaciji x
Robert Šket, 2025, master's thesis

Abstract: V magistrski nalogi preučujemo problematiko stresa na delovnem mestu in ugotavljamo njegovo povezavo s pojavom tihega odhajanja zaposlenih. Stres je eden največjih in najpomembnejših izzivov sodobnega delovnega okolja. Stres vpliva tako na posameznike, kot na organizacije. Izvori stresa so tako izven delovnega okolja, kakor v njem. Dejavniki v delovnem okolju, ki zaposlenim povzročajo stres vplivajo na motivacijo zaposlenih, poveča se tveganje za različne zdravstvene težave, izgorelost itd. V organizaciji se lahko pojavi tudi tiho odhajanje zaposlenih. Negativne posledice stresa se kažejo tudi na upadu produktivnosti in uspešnosti organizacije. Glavni cilj naše raziskave je bil ugotoviti, ali stres vpliva na tiho odhajanje zaposlenih v izbrani organizaciji. V teoretičnem delu magistrske naloge predstavljamo koncept stresa, različne vrste stresa, simptome stresa in njegove posledice. Stres povzročajo različni dejavniki, ki jih glede na mesto izvora delimo na stresorje v delovnem okolju (neugodne delovne razmere, slabi odnosi s sodelavci in nadrejenimi, odgovornost za druge zaposlene, časovni pritiski in preobremenjenost idr.) in stresorje izven delovnega okolja. Poznamo številne simptome stresa, tako čustvene, kot fizične, vedenjske in psihološke. Stres povzroča številne negativne posledice za zaposlene in organizacijo, kot so zmanjšana produktivnost, slabše duševno in fizično zdravje zaposlenih, višja fluktuacija in zmanjšanje uspešnosti organizacije. Da bi preprečili te negativne posledice stresa je pomembno, da posamezniki in organizacije izvajajo ukrepe za premagovanje in obvladovanje stresa. Gre za ukrepe, povezane z zdravim življenjskim slogom zaposlenih (zdrava prehrana, telesna dejavnost, joga, meditacija, odsotnost kajenja in psihoaktivnih snovi idr.), kakor tudi za ukrepe, ki se neposredno nanašajo na oblikovanje delovnih mest (preoblikovanje dela, uvedba fleksibilnega delovnega časa, kroženje itd.). Nadalje smo predstavili koncept tihega odhajanja zaposlenih (ang. quiet quitting), ki postaja v organizacijah vse pogostejše. Gre za vedenje, ko zaposleni opravljajo le nujne delovne naloge, da obdržijo zaposlitev. Vzroki za tiho odhajanje so različni: prenizke plače, slabe možnosti za razvoj kariere in napredovanje, nepravično ocenjevanje, slabo delovno okolje idr.. Tiho odhajanje prinaša višjo fluktuacijo zaposlenih, zmanjšano pripadnost zaposlenih organizaciji, znižuje produktivnost in uspešnost organizacije. V empiričnem delu smo preučevali zaznavanje stresa, izvore in posledice stresa, ukrepe za premagovanje stresa ter prisotnost tihega odhajanja med zaposlenimi v organizaciji X. Rezultati raziskave so pokazali, da zaposleni v izbrani organizaciji doživljajo stres zaradi dela, ki ga opravljajo. Ob tem kot najpogostejše stresorje navajajo preobremenjenost, časovne pritiske in težke delovne razmere. Zaposleni kot najpogostejše posledice, ki jih občutijo navajajo čustvenost, občutek utrujenosti, izčrpanosti in izgorelosti ter živčnost in napetost. Za premagovanje stresa zaposleni največkrat določijo prioriteto delovnih nalog, poiščejo pomoč sodelavca ter si vzamejo kratek odmor. Po drugi strani pa kot ukrepe, ki jih najpogosteje izvaja organizacija navajajo spodbujanje sodelovanja med zaposlenimi, spodbujanje zdravega načina življenja ter omogočanje sodelovanja pri izboljšavah delovnega okolja in organizacije dela. Prav tako smo ugotovili, da je tiho odhajanje zaposlenih v izbrani organizaciji prisotno in da stres vpliva na pojav tihega odhajanja zaposlenih. Za zmanjšanje obeh negativnih dejavnikov bi bilo smiselno izvesti razbremenitev zaposlenih s preoblikovanjem delovnih mest in zaposlitvijo dodatnega kadra.

Statistically significant differences in AI support levels for project management between SMEs and large enterprises
Polona Tominc, Dijana Oreški, Vesna Čančer, Maja Rožman, 2024, original scientific article

Abstract: Background: This article delves into an in-depth analysis of the statistically significant differences in AI support levels for project management between SMEs and large enterprises. The research was conducted based on a comprehensive survey encompassing a sample of 473 SMEs and large Slovenian enterprises. Methods: To validate the observed differences, statistical analysis, specifically the Mann–Whitney U test, was employed. Results: The results confirm the presence of statistically significant differences between SMEs and large enterprises across multiple dimensions of AI support in project management. Large enterprises exhibit on average a higher level of AI adoption across all five AI utilization dimensions. Specifically, large enterprises scored significantly higher (p < 0.05) in AI adopting strategies and in adopting AI technologies for project tasks and team creation. This study’s findings also underscored the significant differences (p < 0.05) between SMEs and large enterprises in their adoption and utilization of AI technologies for project management purposes. While large enterprises scored above 4 for several dimensions, with the highest average score assessed (mean value 4.46 on 1 to 5 scale) for the usage of predictive Analytics Tools to improve the work on the project, SMEs’ average levels, on the other hand, were all below 4. SMEs in particular may lag in incorporating AI into various project activities due to several factors such as resource constraints, limited access to AI expertise, or risk aversion. Conclusions: The results underscore the need for targeted strategies to enhance AI adoption in SMEs and leverage its benefits for successful project implementation and strengthen the company’s competitiveness.

Upravljanje talentov v digitalni dobi
Marija Jovičić, 2025, master's thesis

Abstract: Raziskava obravnava digitalizacijo v kontekstu upravljanja talentov in organizacijskega razvoja v digitalni dobi. V današnjem hitrem in dinamičnem poslovnem okolju digitalizacija oblikuje vse vidike poslovanja organizacij, vključno z menedžmentom človeških virov. V tem kontekstu postaja upravljanje talentov vse pomembnejši proces za dosego in ohranjanje konkurenčne prednosti organizacij. Digitalna orodja, kot so umetna inteligenca in sistemi za podporo odločanju, izboljšujejo preglednosti in omogočajo etično usmerjene odločitve, kar pripomore k večji natančnosti in preglednosti v organizacijskih procesih. Hkrati digitalizacija prinaša izzive, kot so povečana konkurenca pri pridobivanju talentov ter izzivi pri usklajevanju poklicnega in zasebnega življenja, kar zahteva uvedbo politik, kot je pravica do odklopa, da bi preprečili izgorelost zaposlenih. Poleg tega digitalna orodja pozitivno vplivajo na razvoj kompetenc, karierni napredek in izboljšanje zadrževanja talentov. Vendar digitalizacija prinaša tudi izzive, kot so manjša osebna interakcija in večja fluktuacija zaposlenih. Digitalizacija torej preoblikuje prakse upravljanja talentov, vendar zahteva premišljeno strategijo za obvladovanje negativnih vplivov, kot so izgorelost in težave pri usklajevanju osebnega in poklicnega življenja. Uspešna implementacija digitalnih orodij v organizacijah je mogoča le, če se upoštevajo izzivi ter oblikujejo ustrezne strategije, ki omogočajo polno izkoriščanje prednosti digitalne preobrazbe. Tako lahko organizacije v celoti izkoristijo potencial digitalnih orodij za razvoj in upravljanje talentov v dinamičnem poslovnem okolju.
Keywords: digitalizacija, upravljanje talentov, osebna blagovna znamka, nenehno učenje, etika v HR, ravnovesje med poklicnim in zasebnim življenjem.

A comparative study using two SEM techniques on different samples sizes for determining factors of older employeeʹs motivation and satisfaction
Maja Rožman, Polona Tominc, Borut Milfelner, 2020, original scientific article

Abstract: The purpose of this article is to present the relationships among older employee stress, motivation, satisfaction, and relationships in the workplace using two different approaches and different sample sizes. Research was implemented on an initial sample of 1013 older employees. In the next step, six smaller samples were calculated using the random selection of cases, namely samples with 25, 50, 100, 250, 400, and 500 older employees. This way the possible impact of sample size on relationships between latent variables using the covariance-based structural equation modeling (CB-SEM) and the partial least squares structural equation modeling (PLS-SEM) methods was assessed. The results on the larger samples have proved to be quite robust since they were confirmed with both approaches. They indicate that stress has a strong and negative impact on employee relationships and also a negative impact on employee satisfaction. Furthermore, employee relationships have a strong and positive impact on satisfaction and a positive impact on employee motivation. In addition, satisfaction has a strong and positive impact on employee motivation. The present paper helps readers to better understand the difference between the CB-SEM and the PLS-SEM methods. Researchers should be encouraged to use both techniques, even though CB-SEM methods have had a long tradition in management and marketing research since both fields heavily rely on psychometric measurement. From the organizational point of view, conclusions highlight the importance of the impact the variables of older employee stress, motivation, satisfaction and employee relations have on each other in the workplace.
