Internet enabled the emergence of social media platforms, opened new markets and changed the way businesses and organizations operate, communicate with their target audience, promote their activities and achievements. Non-profit organizations worldwide use social media platforms and strive to increase user engagement and the number of reactions to achieve their goals. Although in Bosnia and Herzegovina, non-profit organizations use social media platforms, there is no empirical evidence of their success in increasing user engagement and the number of reactions. This study investigates which social media factors have an influence on user engagement, particularly on the number of reactions on Facebook posts. The real data from the period of 15 months were collected from a Facebook business profile of a non-profit organization from Bosnia and Herzegovina. SPSS and Excel were used to analyze the data. According to the research results, the period of publishing and the number of photos have an effect on the number of reactions on Facebook posts, while the amount of text and the day of publishing do not have an effect on the number of reactions.

Conjugated polymers need to be doped to increase charge carrier density and reach the electrical conductivity necessary for electronic and energy applications. While doping increases carrier density, Coulomb interactions between the dopant molecules and the localized carriers are poorly screened, causing broadening and a heavy tail in the electronic density‐of‐states (DOS). The authors examine the effects of dopant‐induced disorder on two complimentary charge transport properties of semiconducting polymers, the Seebeck coefficient and electrical conductivity, and demonstrate a way to mitigate them. Their simulations, based on a modified Gaussian disorder model with Miller‐Abrahams hopping rates, show that dopant‐induced broadening of the DOS negatively impacts the Seebeck coefficient versus electrical conductivity trade‐off curve. Increasing the dielectric permittivity of the polymer mitigates dopant‐carrier Coulomb interactions and improves charge transport, evidenced by simultaneous increases in conductivity and the Seebeck coefficient. They verified this increase experimentally in iodine‐doped P3HT and P3HT blended with barium titanate (BaTiO3) nanoparticles. The addition of 2% w/w BaTiO3 nanoparticles increased conductivity and Seebeck across a broad range of doping, resulting in a fourfold increase in power factor. Thus, these results show a promising path forward to reduce the dopant‐charge carrier Coulomb interactions and mitigate their adverse impact on charge transport.

PurposeThe aim of this study is to investigate a mediation role of leadership over business performance and socioemotional wealth, within two Bosnian family businesses. This research purpose brings interesting highlights regarding how family businesses embedded the role of leadership that it might have a tremendous influence on business performance while tuning the socioemotional wealth.Design/methodology/approachThis study is based on qualitative research methodology. The sample is collected based on a purposive sampling method as in most qualitative studies. As the instrument for data collection is concerned, in-person-semi-structured interview has been employed with the owner-manager of each particular-family firm. Thus, two case studies were conducted and analyzed.FindingsThe research contributes both to the theory and the practice. From the theoretical perspective, it contributes to the theoretical knowledge of leadership as an important role in relationship between the socioemotional wealth and business performance. The practical contribution of this research could be summed up in the sense that business owners should seek to employ positive leadership vibes to create a good socioemotional wealth so that would be positively reflected in overall business performance of a family business. Other findings are further discussed.Originality/valueScarce empirical research offers mixed results while theoretical propositions that organizational governance (leadership) plays an important role in this relationship, is somehow neglected. Hence, this is the first empirical study on this particular that investigates this topic in Bosnia and Herzegovina (BiH), even in the Balkan region.
