- ItemPerformance of Family Businesses in the Specific Conditions of CEE Countries: The Case of the Czech Republic(SAV SR, 2024-08-23) Režňáková, Mária; Karas, Michal; Srbová, Pavla; Pěta, Jan; Michalíková, EvaMany authors point out that family businesses in the CEE region due to a dif-ferent historical development might exhibit specific features and because of that deserve specific attention. The presented paper aims to contribute to this effort by exploring factors driving the performance of family businesses in the Czech Republic, in course of the research a panel of 7,995 businesses was analyzed by using the linear mixed effects model. The common problem of missing data, especially on micro-enterprises, was addressed by using CHAID methodology. We found that the factors driving family business performance differs between micro and SMEs segments of businesses, while the effect of families is most significant in terms of the model’s slope rather than constant.
- ItemGreen public procurement in the most visited European museums: a comparison and a mapping(SPRINGER NATURE, 2024-03-13) Plaček, Michal; Rossel, Jordi; Valentinov, Vladislav; Křápek, MilanWhile scholarly research on green public procurement (GPP) keeps growing, until now it has paid little attention to museums that must make decisions about GPP implementation. This paper breaks new ground by exploring GPP implementation in the most visited European museums. The proposed conceptual framework allows a comparison and a mapping of museums' GPP implementation levels while taking account of how these levels are related to the national GPP performance. Complementing this framework with the analysis of the up-to-date data from the Tender Electronic Daily database yields two central findings. First, museums that formalized their GPP policies in their strategic organizational documents exhibit higher levels of GPP implementation than other museums that have not done so. Second, the majority of the investigated museums follow national trends of GPP implementation, with examples of exceeding or falling below these trends being rare. The article is important for policy makers and practitioners as it highlights the importance of the factor of institutionalization of green procurement in individual organizations, which is crucial for successful implementation of green procurement.
- ItemProject Management in the Time of VUCA: Threat or Opportunity?(University of Hradec Králové, 2024-04-10) Košťálová, Jana; Doskočil, Radek; Širáňová, Lenka; Lacko, BranislavThis study addresses the "projectification of society" and its alignment with the VUCA framework (Volatility, Uncertainty, Complexity, Ambiguity). Four widely used international project management standards—PMI, IPMA, PRINCE2, and PM2—are evaluated for their suitability in the VUCA environment. The research employs a multicriteria approach, specifically the Weighted Sum Approach method, considering factors like volatility, uncertainty, complexity, and ambiguity. The selected standards are scrutinized based on their adaptability to VUCA challenges, with a focus on PMBOK, IPMA, PRINCE2, and PM2. The seventh edition of the PMBOK has been evaluated on the first position. The study emphasizes the crucial role of selecting an appropriate project management standard for success in navigating the dynamic VUCA world. The results confirmed this and brought a number of recommendations for managing projects in a VUCA environment.
- ItemThe focal boundary value problem for strongly singular higher-order nonlinear functional-differential equations(Springer Nature, 2015-01-30) Mukhigulashvili, Sulkhan; Půža, BedřichThe a priori boundedness principle is proved for the two-point right-focal boundary value problems for strongly singular higher-order nonlinear functional-differential equations. Several sufficient conditions of solvability of the two-point right-focal problem under consideration are derived from the a priori boundedness principle. The proof of the a priori boundedness principle is based on Agarwal-Kiguradze type theorems, which guarantee the existence of the Fredholm property for strongly singular higher-order linear differential equations with argument deviations under the two-point right-focal boundary conditions.
- ItemThe nonlinear Kneser problem for singular in phase variables second-order differential equations(Springer, 2014-09-30) Půža, Bedřich; Partsvania, NinoFor the singular in phase variables differential equation u'' = f (t, u, u') ), sufficient conditions are found for the existence of a solution satisfying the conditions Phi(u) = c, u(t) > 0, u'(t) < 0 for t > 0, where Phi : C([0, a]; R+) to R+ is a continuous nondecreasing functional, c > 0, and a > 0.
