Opis: This study investigated the impact of information systems (IS) success on Project Success (PS) within hybrid and remote work environments, drawing empirical evidence from the world's largest consulting firm. By integrating the DeLone and McLean IS success model with established PS frameworks, the research examined how IS components—system quality, user satisfaction, and use/ intent to use—influence key PS dimensions: project management success, impact on the team, impact on the customer, and project investment success. Data from 198 employees were analyzed using structural equation modeling, confirming all hypothesized relationships. Results revealed that IS net benefits significantly enhance PS across all dimensions, while system quality and user satisfaction further drive IS effectiveness. The study underscores the critical role of robust digital infrastructure in optimizing project outcomes, offering theoretical insights and practical recommendations for organizations navigating hybrid work models. Limitations and future research directions are also discussed.

Opis: Missing observations can arise due to the effort required to answer many questions in long surveys and the cost required to obtain some responses. Implementing a planned missing design in surveys helps reduce the number of questions each respondent needs to answer, thereby lowering survey fatigue and cutting down on implementation costs. The three-form and the two-method design are two different types of planned missing designs. An important consideration when designing a study with omissions by design is to know how it will affect statistical results. In this work, a simulation study is conducted to analyze how the usual fit measures, root mean square error of approximation (RMSEA), standardized root mean square residual (SRMR), comparative fit index (CFI), and Tucker-Lewis index (TLI) perform in the adjustment of a Structural Equation Model. The results revealed that the CFI, TLI, and SRMR indices exhibit sensitivity to omissions with small samples, low factor loadings and large models. Overall, this study contributes to our understanding of the importance of considering omissions by design in market research.

Opis: This dissertation examines the emergence of the gig economy under the impact of digitalisation, focusing on one alternative form of work – freelancing. Over the past two decades, new and contemporary occupational concepts have emerged in the context of technological advances and the reorganisation of employment relationships in the wake of digitalisation. Technology has enabled many things to be done online or remotely, and for work to be broken down into smaller components in the form of projects. Scholars explain that the most important innovations influenced by digitalisation are the development of new business models characterised by less dependence on physical elements or dematerialisation of processes, as seen in the “gig economy”. In the gig economy, very short-term tasks or projects within specific activities are performed by individual self-employed workers, usually coordinated through online platforms or applications. As a result, many workers are able to complete tasks in a more efficient and fragmented manner. Unlike traditional careers characterised by hierarchical advancement, organisational career management, and low mobility, many individuals are also becoming more mobile and self-directed in their careers. As a result of these developments, new work arrangements have emerged that are taking up an increasingly large share of the labour market in major economies (such as the US and UK), heightening concerns about how workers are classified and raising questions about entrepreneurship, future career development, work-life balance, employment law frameworks, and social protections. These flexible work arrangements are often referred to as alternative and are performed by independent contractors, known as freelancers. Therefore, the dissertation was carried out to examine this alternative form of work at the national level in Slovenia, and explore the issue of career satisfaction, and specifically whether freelance work allows fulfilment through project work. In this dissertation, a freelancer refers to a self-employed individual without employees who is responsible for paying their own taxes and welfare contributions, works on projects for multiple clients, and works remotely, usually from home. The development of the research model for the purposes of this dissertation is based on Van den Born and Van Witteloostuijn’s (2013) freelancer success model, which is based on the intelligent career framework that consists of three interrelated variables: knowing why, knowing how, and knowing who. The ‘knowing why’ variable mainly reflects our personality traits and motivation. The ‘knowing how’ variable reflects human capital, while the ‘knowing who’ variable reflects social capital inside and outside the workplace (Parker & Arthur, 2004). However, the external environment is missing in this model. Therefore, the dissertation also included the external part, i.e. the external environment consisting of the characteristics of the entrepreneurial ecosystem: government programs, cultural and social norms, legal system support, and digital support. As Slovenia and other EU member states are implementing national strategies for digital transformation, this dissertation provides insight into freelancers in Slovenia and their perceptions of certain aspects of external environmental factors, which may be helpful in evaluating current digital strategies and future policy proposals and decisions. Therefore, the main objective of the dissertation was to test a conceptual model that links multidimensional variables that influence the perceived success of freelancers based on a review of the literature and empirical research, and thus to learn certain specific characteristics of the group of entrepreneurial, self-employed individuals known as freelancers, and to determine the extent to which personality traits, human and social capital, and motivation of the individual, as well as a supportive environment (entrepreneurial ecosystem),

Opis: V diplomskem seminarju, ki sem ga napisal, sem se v prvem delu osredotočil na opisovanje neposrednih tujih investicij (NTI), nato sem nadaljeval s predstavitvijo izbranih teorij, kot sta npr. Heckscher-Ohlinov model in Dunningova teorija, na koncu pa prikazal še vplive NTI na izbrana gospodarstva (Kitajska, Poljska, Češka, Slovanška, Madžarska in Slovenija). V prvem delu sem tako med drugim izpostavil dejstvo, da so NTI sestavni del procesa globalizacije in da so tekom opazovanega obdobja od leta 1987 oziroma 1995 do 2007 postale tudi ena izmed najpogostejših in najbolj dinamičnih vrst toka kapitala v analiziranih državah (Kitajska, Poljska, Češka, Slovanška, Madžarska in Slovenija). V drugem delu sem predstavil korelacijo med NTI in njihovimi vplivi na rast oziroma upad ekonomskih variabel. Celotna predstavitev poteka v več sklopih. Z uporabo podatkovnih baz, kot so European Bank for Reconstruction and Development database, World Development Indicators Database from the World Bank, The Organisation for Economic Co-operation and Development (OECD) data in Chinese National Bureau of Statistics yearbooks data sem eliminiral možnost uporabe nepreverjenih in statistično neenotnih podatkov, kot dodatno pomoč pa so mi predstavljale raziskave in članki priznanih avtorjev, kot so Robert E. Lipsey, Blomstrom, Kokko, Dunning, Gujarati in drugi Eden izmed načinov analize vpliva in korelacije NTI na različne ekonomske variable je uporaba ekonometričnih metod. Z uporabo regresijske enačbe sem tako poskušal razložiti in prikazati vpliv in korelacijo med neposrednimi tujimi investicijami (NTI) na ravni bruto domačega proizvoda (BDP), rast izvoza, stopnjo brezposelnosti in vpliva na okolje. Pri tem sem si pomagal s postavitvijo štirih hipotez. Hipoteze so bile sledeče: hipoteza 1 je temeljila na predpostavki, da prilivi neposrednih tujih naložb povečajo ravni BDP, hipoteza 2 je predpostavljala, da NTI povečajo izvozno dejavnost, hipoteza 3 je temeljila na predpostavki, da NTI vplivajo na zmanjšanje ravni brezposelnosti, in hipoteza 4 na predpostavki, da se ravni onesnaženosti (CO2 emisije) povečujejo s pritokom neposrednih tujih naložb. Pri prikazovanju rezultatov in matematičnih operacijah sem uporabljal linearni ekonometrični model. Ker sem predvideval, da bodo BDP, izvoz in brezposelnost povezani/korelirani, sem uporabil SEM model (structural equation model), medtem ko sem zaradi raznolikosti podatkov le-te zbiral s kombinacijo »time series and cross section« metode. Čeprav so spremenljivke nenormalno porazdeljene glede na elementa asimetrije in sploščenosti, mi ta nenavadna porazdelitev ni onemogočila neizvedljivost testa linearne regresije. Zaključek raziskave temelji na dejstvu, da obstajajo tako pozitivni kot negativni učinki NTI, katerih glavni nositelj so transnacionalna podjetja (TNP). Čeprav v osnovnem delu raziskave nisem eksplicitno izpostavil negativnih in pozitivnih učinkov NTI, je splošno znano dejstvo, da določeni ljudje iz stroke neposredne tuje investicije podpirajo, medtem ko jih drugi ne, saj menijo, da le-te niso pozitivne, oziroma lahko v določeni meri državi tudi škodijo. K mojemu povzetku ideje ekonomistov, ki imajo NTI za pozitivne oziroma negativne, pa je prispevalo dejstvo, da je osnovni del raziskave pokazal, da je zelo malo spremenljivk, pri katerih je bila ugotovljena zelo visoka korelacija. Natančnejša analiza je pokazala, da so NTI močno negativno korelirane z onesnaževanjem, kar je v nasprotju z domnevo, da bi povečanje tujih neposrednih investicij pripeljalo do večjega onesnaženja. Individualni test linearne regresije pa je na primeru Poljske pokazal, da je povečanje NTI dejansko imelo negativen vpliv na gospodarsko rast v tej državi, čeprav ta ugotovitev ni v skladu z ekonomsko teorijo in izvirno hipotezo, da pritoki NTI povečajo ravni bruto domačega proizvoda. Tako sem po svoji presoji zaključil, da imajo NTI pozitivno-negativni učinek. V zaključku sem tudi izpostavil, da na končni rezultat, ki ga imajo NTI na neko ekonomsko spre
