The influence of organizational factors on the adoption of energy efficiency measures in companies
Aleksandar Vučković, Marija Džunić, 2023, izvirni znanstveni članek

Opis: This paper aims to research the organizational factors influencing the implementation of energy efficiency measures in companies. The analysis was performed on a sample of companies from Serbia included in the World Bank Enterprise Survey. The raw data collected by the World Bank were utilized to analyze the correlation between various organizational factors and the adoption of energy efficiency measures. The analysis revealed a statistically significant correlation between management maturity and the implementation of energy efficiency measures in companies. These findings suggest that improving energy efficiency is not an isolated process but rather closely related to the maturity of management practices, highlighting the importance of comprehensive organizational development for achieving optimal energy management.

Application of normalization method to fracture toughness testing of welds with pronounced strength heterogeneity : doctoral disertation
Primož Štefane, 2022, doktorska disertacija

Opis: This doctoral dissertation presents the results of an extensive fracture testing programme of welds with pronounced strength heterogeneity. Purpose of this programme was to determine fracture toughness of heterogeneous welds that contain a midplane crack. Application of standardized fracture testing methods in heterogeneous welds might lead to overestimation or underestimation of fracture toughness and consequentially to inaccurate assessment of structural integrity. Reasons for that are variations in mechanical properties of different material regions in the weld which have a significant impact on development of deformation at the crack tip, and consequently on the crack driving force. Experimental procedures in scope of this research include fabrication of weld sample plates, that were welded with MAG process. The welds were fabricated using two different electrodes, one with higher and one with lower mechanical properties, with respect to base material S690QL in order to replicate extreme variations of mechanical properties in the weldment. Fabricated welds were then characterized in detail using metallography, three-point bend impact testing, indentation hardness measurements and tensile testing of flat miniature and round bar standard tensile specimens. Resistance of welds to stable tearing was investigated by fracture testing of square surface cracked SE(B) specimens containing a weld midplane notch. J-integral has been estimated from plastic work, using the normalization data reduction method that is included in standard ASTM E1820. The advantage of the normalization data reduction method is that no special equipment or complex testing method is needed to measure ductile crack growth during fracture testing. The ductile crack growth is determined directly from the load-displacement record, by applying appropriate calibration function and physical lengths of initial and final cracks that were measured post-mortem with the nine-point method. Several correction factors had to be calibrated in order to successfully implement the normalization data reduction method to fracture testing of welds with pronounced strength heterogeneity. For that reason, parametric finite element analyses were conducted for several weld configurations. Finite element models incorporated plane strain conditions in order to provide calibrated factors that comply with plane strain equations included in ASTM E1820. Additionally, crack tip constraint has been extensively analysed and correlated with the plastic deformation fields. This clarified altered deformation behaviour of modelled welds in comparison with the base material and corresponding effect on fracture toughness. Finally, calibrated factors were applied to computation of J-integral from data that were measured during fracture testing. J-R resistance curves were constructed for the tested heterogeneous welds and compared to the ones of the base material. This directly showed the effect of variations of mechanical properties on the weld fracture behaviour.

Analiza pričakovanih učinkov uvedbe oblačne rešitve »SAP Success Factors«
Špela Mahorič, 2019, magistrsko delo

Opis: Eden izmed najpomembnejših dejavnikov pri doseganju poslovnih ciljev podjetja so usposobljeni zaposleni, ki se uspešno spopadajo z novimi razmerami na trgu. Zato je kadrovska funkcija v podjetjih izjemnega pomena, saj izbira kandidate, ki so za dosego poslovnih ciljev najbolj primerni. Na eni strani imamo tradicionalno plat kadrovske funkcije, pri kateri podjetje zagotovi zaposlene in poskrbi, da ti zaposleni dobijo za svoje delo primerno plačilo. Na drugi strani pa imamo strateško plat kadrovske funkcije. Pri tej gre za to, da podjetje pridobi prave zaposlene na pravih delovnih mestih, ki delajo prave stvari na pravi način, hkrati pa jim omogoča pravi razvoj za prihodnost. Obe strani kadrovske funkcije lahko poenostavimo s pomočjo kadrovskih informacijskih sistemov. Ti omogočajo, da podjetje zmanjša kadrovsko papirno dokumentacijo in upravlja z zaposlenimi s pomočjo informacijskega sistema. Začetki kadrovskih informacijskih sistemov so bili v opravljanju nalog tradicionalne plati. Ob razvoju informacijske tehnologije pa so ponudniki kadrovskih informacijskih sistemov razvili tudi strateško plat kadrovske funkcije. Kadrovski informacijski sistemi so sredstvo za pridobivanje, shranjevanje, analiziranje in posredovanje informacij različnim uporabnikom. Običajno obsegajo ohranjanje zaposlenih, zaposlovanje, upravljanje z zaposlenimi, upravljanje plačilnega prometa, načrtovanje kadrovskih virov, upravljanje z izobraževanji, spremljanje uspešnosti, samoupravljanje zaposlenih, načrtovanje, upravljanje odsotnosti, analitiko, prerazporeditve zaposlenih in drugo. Na trgu obstaja veliko ponudnikov kadrovskih informacijskih sistemov. Noviteta predvsem na slovenskem trgu pa je SAP Success Factors. Rešitev še vedno omogoča opravljanje enakih kadrovskih funkcij, le da je s SAP Success Factors to poenostavljeno in dostopnejše. V magistrski nalogi je mogoče spoznati in lažje razumeti kadrovsko funkcijo v podjetju in področja upravljanja s kadri. Podrobneje so opredeljeni kadrovski informacijski sistemi, njihov razvoj in funkcije ter ponudniki kadrovskih informacijskih sistemov. Izmed vseh ponudnikov smo izbrali rešitev SAP Success Factors, ki je nastala leta 2011 ob združitvi podjetij SAP d. o. o. in Success Factors. V drugem delu je na podlagi podjetja X predstavljen obstoječi kadrovski informacijski sistem in nekatere funkcije, kot sta spremljanje uspešnosti zaposlenih in upravljanje nasledstev. Obstoječi kadrovski informacijski sistem v tem podjetju namreč ne predstavlja takšne učinkovitosti, kot bi ga podjetje z uporabo sistema želelo. Nekaterih funkcij ni mogoče informacijsko podpreti ali pa so za to potrebni zunanji zaposleni, kar prinaša podjetju visoke stroške. V magistrski nalogi smo v demo verziji programa SAP Success Factors predstavili procese, ki bi izbranemu podjetju izboljšali upravljanje s kadri. Za konec smo naredili primerjalno analizo med obstoječim kadrovskim informacijskim sistemom in programom SAP Success Factors. Ugotovili smo, da bi podjetje z vpeljavo sistema SAP Success Factors izboljšalo nekatere procese, zmanjšalo papirno dokumentacijo, izboljšalo kadrovsko poročanje, informacijsko podprlo letne pogovore, izboljšalo motivacijo zaposlenih in drugo.

Social CRM adoption and its influence on customer relationship performance -SMEs perspective
Marjeta Marolt, 2018, doktorsko delo/naloga

Opis: Social media (SM) is challenging the traditional relationship between enterprises and customers. The flow of information has become multidirectional, interconnected and difficult to predict. In order to create superior customer experiences, enterprises need to systematically use SM together with other customer relationship management (CRM) technologies. Customer loyalty and satisfaction can only be achieved through effective use of social media. Despite a rich body of literature on CRM innovation adoption, there is lack of research on social CRM adoption and its use, especially with regard to micro, small and medium-sized enterprises (SMEs). Specifically, studies focus either on the of social CRM adoption factors or on the impact of social CRM use on customer relationship performance. Therefore, there is a need for comprehensive representation of the entire chain of social CRM adoption constituted by the adoption factors, the extent of social CRM adoption and its influence on customer relationship performance. The aim of this research is to provide a conceptual clarity of the extent of social CRM adoption and develop a research model for exploring the effect of different factors on the extent of social CRM adoption and the impact of the extent of social CRM adoption on customer relationship performance in the context of B2C SMEs. In order to achieve a more comprehensive overview of the phenomenon under investigation, this study employed an exploratory, sequential mixed method approach. Based on the literature review, semi-structured interviews were conducted with six purposefully selected B2C SMEs. The findings from the qualitative phase of the study were used to develop a research model that guided the quantitative phase of the study. The empirical data were collected using self-administrated questionnaires. The data analysis was based on 119 B2C SMEs in Slovenia. The findings confirmed that social CRM is a complex phenomenon even for SMEs and suggest two-dimensional conceptualization of the extent of social CRM use: customer-facing processes and relational information processes. Regarding the factors of the extent of social CRM use our findings revealed that they are diverse, ranging from technological, organizational, to environmental. Furthermore, empirical evidence from this research also suggests that extensive use of social CRM positively affects customer relationship performance. All in all, through the theoretical discussion and empirical assessment, the thesis provides more detailed insights into the B2C SMEs social CRM adoption situation and provides a basis for further research.

Innovation leaders, modest innovators and non-innovative SMEs in Slovakia : key factors and barriers of innovation activity
Ľubica Lesáková, Petra Gundová, Pavol Kráľ, Andrea Ondrušová, 2017, izvirni znanstveni članek

Opis: Background and Purpose: The field of innovation represents for small and medium enterprises (SMEs) a fundamental challenge. If the number of innovative SMEs is to rise, it is necessary to identify key factors determining their innovation activity and eliminate the innovation barriers. The main purpose of the paper is to present the results of primary research focused on identification (evaluation) of key factors and barriers determining innovation activities in Slovak SMEs. The division of SMEs into three groups of enterprises: innovation leaders, modest innovators and non-innovators enables to identify the differences in managers’ perception of the main factors and barriers determining innovation activities in various types of SMEs and to formulate policy implications for Slovak SMEs. Design/Methodology/Approach: Results of the empirical research were processed using MS Excel and the statistical analysis of the data in R3.2.4. statistical system was done. For statistical tests we assumed significance level (α = 0.1). Results: Evaluating the importance of the key factors a majority of enterprises (64.71%) indicated financial resources as the most important factor for the innovations. There is no statistically significant difference in individual (analysed) factors between innovation leaders, non-innovators and innovation followers (modest innovators). The results gained from Fisher exact test (p-value = 0.11) indicated a small difference in evaluating the significance of individual barriers between innovation leaders, non-innovators and modest innovators. Majority of enterprises also see as the main barriers to develop innovation activities bureaucracy and corruption and inappropriate state support of innovation activities. Conclusion: The main implications (conclusion) coming from the research are basic recommendations for state policy makers as well as SME’s managers to foster innovation activities in enterprises. They refer to the areas of financial resources, high-quality human resources, cooperation and participation of SMEs in different networks and clusters, systematic institutional support to SMEs, well-created vision and clearly formulated aims, and willingness of enterprises to innovate. Recommendations are summarised following the results of factor’s and barrier’s evaluation.

The influence of personality characteristics on individual competencies of work group members : a cross-cultural study
Georg Kodydek, Ronald Hochreiter, 2013, izvirni znanstveni članek

Opis: In this article, we investigate how college students and graduates with diverse backgrounds experience working in groups by focusing on their perceptions regarding group work, attribution of leader coaching, and self-perspectives of personality traits. Moreover, this article explores relationships between personality factors (using the Big Five factors) and selected individual competencies from Bartram’s Great Eight Competencies (2005). We furthermore review current management research on competency management, personality, and also identify current trends for young professionals who are about to enter the job market. This study was conducted in an experimental setting at a large European business school. Participants were 80 business students from Austria, Turkey, China, and the United States of America with a fairly even gender split who had to work on tasks in homogeneous and heterogeneous settings. We assess participants’ ratings following Rammstedt and John’s Big Five Inventory (2007) and a modified version of Wageman, Hackman and Lehman’s Team Diagnostic Survey (2005) that we enhanced accordingly. Results are analyzed and discussed with relation to global challenges and developments regarding competencies, diversity, and group work.

The impact of managers on successful ERP implementation
Franc Ravnikar, 2010, izvirni znanstveni članek

Opis: Lately, Enterprise Resource Planning (ERP) has been implemented in public organizations and organizations without competition in the marketplace. It is the ERP system that is almost as badly needed for the competitiveness and success of those organizations in the marketplace. The main reason lies in the fact that operating costs have to be reduced and the optimization of business processes is an option which nowadays is normally implemented together with new ERP. The success rate of ERP implementation remains very low with up to a 90% failure rate, as it is quoted in a lot of researches. Critical success factors (CSF) which influence successful ERP implementation are identical in all organizations. The main goal of this research is to find out the managers' impact on the critical success factors and thus their impact on the successful ERP implementation. Top management support is the most important critical success factor for successful ERP implementation, regardless of the fact whether the organization is on the market or not.

Psychosocial factors in the development of low back pain among professional drivers
Friderika Kresal, Tine Bertoncel, Maja Meško, 2017, izvirni znanstveni članek

Opis: Background and purpose: Professional drivers as a group are exposed to high risk of developing low back pain due to ergonomic factors and work conditions. The purpose of the study was to examine to what extent the low back pain occurs among Slovene professional drivers as a result of the development of various psychosocial factors. Methodology: The study involved 275 respondents (professional bus drivers, car/van drivers, international truck/ lorry drivers, and ambulance car drivers). Hypotheses were tested using multivariate statistical method (regression analysis) and analysis of variance. Data were collected by structured questionnaire comprised of three parts: socio-demographic data, basic psychosocial factors causing low back pain, and incidence, duration and severity of low back pain as a result of psychosocial risk factors, was implemented. Results: The results of quantitative survey suggest that low back pain is mostly caused by lifting and carrying heavy loads, inadequate working conditions, poor physical fitness, regular nights out, shift work, and stress. Only the impact of gender on low back pain distress among professional drivers was confirmed, predominantly among bus drivers and lorry drivers on international routes. Low back pain occurrence was less common, albeit not statistically significant, among professional drivers of vans and passenger cars. Conclusion: Our study suggests that psychosocial factors are also important cause for the development of low back pain among professional drivers and can limit the quality of their social and professional lives.
