Development of a cluster manager's competencies towards competitiveness

Cluster managers have less authority compared to managers in companies, with the work of cluster managers based rather on negotiation than on issuing instructions. Nevertheless, dynamic changes regarding environment and customer needs in general have taken place, and ensuring that employees have adequate knowledge and skills has become necessary for companies to gain a competitive advantage. Thus, the development of competencies in cluster management is more relevant in terms of the changing nature of competencies in order to enhance competitiveness. A research gap, however, has emerged in terms of studies analyzing developmental activities to increase the skills and knowledge of cluster managers, including their abilities to support cluster development and related competitiveness issues. The main objective of the present paper is to identify possible methods of developing cluster managers competencies in order to increase the competitiveness of cluster organizations. To accomplish these research goals, the paper employs semi-structured interviews with Czech cluster managers, with primary data analyzed via coding based on thematic analysis and codes subsequently grouped into categories for conceptualization. The findings indicate that development of cluster managers lags behind in terms of lack of motivation enhancement and time, lack of finance, idleness, negative experiences, administrative tasks as well as personal traits. The main criteria for developing competencies in cluster organizations are reflected in activities focused on the ability to innovate, lead and protect in terms of trust building, all skills essential for enhancing the competitiveness of cluster organizations. Cluster managers select development activities based on topics and references to educational activities which they estimate mainly from practical experience based on recommendations by experienced practitioners. Finally, the study puts forth practical guidelines regarding self-development methods recommended by the respondents for developing competencies in cluster development and competitiveness.[RO/2016/07

Modelling QoS in Computer Networks

Kvalita služeb (QoS) je důležitým aspektem v oblasti počítačových sítí, ale je také velkou výzvou. Poskytnutí záruky QoS je ještě náročnější, když přidáte složitosti do sítě, jako jsou hlasové a video aplikace. Tato diplomová práce se zaměřuje na modelování a simulaci QoS v diskrétním simulačním systému OMNeT++. Implementace několika technik pro simulaci QoS je přidána do OMNeT++ v rámci této práce. Všechny implementované moduly jsou ověřené vůči QoS nástrojům na reálných směrovačích. Poslední část práce představuje možnosti simulace QoS v nově implementovaných modulech.Quality of service (QoS) is an important consideration in networking, but it is also a significant challenge. Providing QoS guarantees becomes even more challenging when you add the complexities to the network like voice and video applications. This master's thesis focuses on QoS modeling and simulation in discrete event simulation system OMNeT++. The implementation of multiple techniques for QoS simulation is added to OMNeT++ within this work. All implemented modules are validated against the QoS tools on real routers. The last part of the work presents the possibility of QoS simulation in newly implemented modules.

Rethinking group dynamics in public organizations: Starting point for behavioral public strategy research

Purpose: The paper aims to explore group dynamics in the management and administration of the selected public organization. Specific interest is given to two fundamental domains of group dynamics: 1) communication processes and interaction patterns; 2) group cohesion and climate. Methods: The approach is based on in-depth interviews with public employees representing various departments of a public organization. A total of 34 subjects participated in this study and provided primary data for coding and finding patterns. Both investigator and data triangulation are used to conceptualize group dynamics in the public organization. Results: Public organizations' employees face hardships in knowledge sharing and tend to misunderstand the agenda between various departments and citizens. The participation of citizens in decision making could be seen as a 'double edged sword' that contributes to the implementation of public projects, but often derails efficient organizational processes. Public organizations struggle with employee turnover, insufficient treatment of employee wellbeing, and unwillingness to pursue personal development. Conclusion: Understanding and further defining the level of group dynamics among public employees is the first step towards adopting innovation approaches. The paper highlights the implications for public organizations with an overview of the behaviors needed for a smooth strategy process in development planning based on organizational forces that leads to a better understanding of group dynamics.project of the Internal Grant Agency of Tomas Bata University in Zlin [RO/2022/07

The dryas iulia genome supports multiple gains of a W chromosome from a B chromosome in butterflies

In butterflies and moths, which exhibit highly variable sex determination mechanisms, the homogametic Z chromosome is deeply conserved and is featured in many genome assemblies. The evolution and origin of the female W sex chromosome, however, remains mostly unknown. Previous studies have proposed that a ZZ/Z0 sex determination system is ancestral to Lepidoptera, and that W chromosomes may originate from sex-linked B chromosomes. Here, we sequence and assemble the female Dryas iulia genome into 32 highly contiguous ordered and oriented chromosomes, including the Z and W sex chromosomes. We then use sex-specific Hi-C, ATAC-seq, PRO-seq, and whole-genome DNA sequence data sets to test if features of the D. iulia W chromosome are consistent with a hypothesized B chromosome origin. We show that the putative W chromosome displays female-associated DNA sequence, gene expression, and chromatin accessibility to confirm the sex-linked function of the W sequence. In contrast with expectations from studies of homologous sex chromosomes, highly repetitive DNA content on the W chromosome, the sole presence of domesticated repetitive elements in functional DNA, and lack of sequence homology with the Z chromosome or autosomes is most consistent with a B chromosome origin for the W, although it remains challenging to rule out extensive sequence divergence. Synteny analysis of the D. iulia W chromosome with other female lepidopteran genome assemblies shows no homology between W chromosomes and suggests multiple, independent origins of the W chromosome from a B chromosome likely occurred in butterflies

Chromosome fusion affects genetic diversity and evolutionary turnover of functional loci, but consistently depends on chromosome size

Major changes in chromosome number and structure are linked to a series of evolutionary phenomena, including intrinsic barriers to gene flow or suppression of recombination due to chromosomal rearrangements. However, chromosome rearrangements can also affect the fundamental dynamics of molecular evolution within populations by changing relationships between linked loci and altering rates of recombination. Here, we build chromosome-level assembly Eueides isabella and, together with a recent chromosome-level assembly of Dryas iulia, examine the evolutionary consequences of multiple chromosome fusions in Heliconius butterflies. These assemblies pinpoint fusion points on 10 of the 20 autosomal chromosomes and reveal striking differences in the characteristics of fused and unfused chromosomes. The ten smallest autosomes in D. iulia and E. isabella, which have each fused to a longer chromosome in Heliconius, have higher repeat and GC content, and longer introns than predicted by their chromosome length. When fused, these characteristics change to become more in line with chromosome length. The fusions also led to reduced diversity, which likely reflects increased background selection and selection against introgression between diverging populations, following a reduction in per-base recombination rate. We further show that chromosome size and fusion impact turnover rates of functional loci at a macroevolutionary scale. Together these results provide further evidence that chromosome fusion in Heliconius likely had dramatic effects on population level processes shaping rates of neutral and adaptive divergence. These effects may have impacted patterns of diversification in Heliconius, a classic example of an adaptive radiation

Einflussfaktoren auf Gründungsdispositionen und Entrepreneurship-Merkmalen von Studierenden – Ein Vergleich von Russland und Deutschland

Dieser Beitrag geht mit dem internationalen Forschungsprojekt „Gründungen und Entrepreneurship bei Studierenden“ (GESt-Studie) einher, das zum Ziel hat, Gründungsneigungen und Entrepreneurship-Merkmale von Studierenden aus verschiedenen Ländern zielgruppendifferenziert zu analysieren, um daraus bedarfsorientierte Handlungsempfehlungen für eine adäquate Konzeptionierung von Gründungsausbildung und Gründungsförderung abzuleiten. Die Ergebnisse dieses Ländervergleiches veranschaulichen, dass die befragten Studierenden in Russland ein höheres Gründungsinteresse repräsentieren und sich insgesamt deutlich stärker mit Entrepreneurship beschäftigen als die in Deutschland befragten Studierenden. Allerdings basiert diese in Russland positivere Ausgangsbasis für eine Gründungsrealisierung stärker auf der Gründungsmotivation aus ökonomischer Notwendigkeit, die oftmals nicht auf innovativen Geschäftsideen beruht, heraus. Insgesamt betrachtet sind sowohl den Studierenden in Deutschland, von denen sich etwa jeder Zweite noch gar nicht mit der Gründungsthematik auseinandergesetzt hat, als auch den Studierenden in Russland, die stärker durch fehlende unternehmerische Qualifikationen von der Gründung abgehalten werden, insbesondere gründungsspezifische Grundkenntnisse und unternehmerische Fähigkeiten zu vermitteln, was fächerübergreifend und während des gesamten Studiums zu erfolgen hat.
