Navigating the Tensions of Digital Transformation in High Reliability Organizations

Why do some organizations enable digital transformation and adjust to market conditions more successfully than others that face delays and fail to overcome resistance or rejection? The objective of my dissertation is to provide in-depth insights into the digital transformation implementation challenges in high reliability organizations. To explore how those complex and risk-averse business settings were primarily concerned with maintaining high reliability in avoiding catastrophes, navigating the tensions and various obstacles around digital transformation. The central tenet of this dissertation is that, in addition to organizational, technological and business model dimensions, which have been the focus of prior research, employees across various organizational layers play an important role in the success or failure of digital transformation efforts. They need to adapt to changing working environments, contribute to developing new digital resilient working routines and enact appropriate cognitive processes. The findings report the multilevel interactions, tensions and paradoxes across different organization hierarchical levels. In addition, the research illuminates the specific self-protective behaviors through which employees derail the transformation process, particularly when the risk culture of an organization or the interest of individuals and groups within the organization are at odds with the vision of digital transformation

Use of the Internet in the process of choosing and buying a holiday at the travel agency Campanatour, s. r. o.

katedra: KMG; přílohy: 1 CD ROM; rozsah: 82The diploma thesis contains theoretical information about travel agencies, internet marketing, internet advertising and search engine optimization. This theoretical information is being imported into practise with the description of basic characterictics of a particular travel agency Campanatour. The main issue of this thesis is to find if and how much the Internet is used in the process of choosing and buying a holiday. That is why the work also focuses on an appereance of a particular subsidiary and also focuses on catalogues that are used during the process of choosing holiday in the travel agency office. The work then deals with the appereance of Internet websites and on the functionality of the online reservation system that is used during the process of choosing the holiday on the Internet. The thesis also contains two researches. One was done through visits in the ravel agency offices and on the websites of three travel agencies. Visits were carried out by the author of the thesis. The second research takes the form of a questionnaire. The main objective of both researches was to determine if and how much the Internet is used in the process of choosing and buying the holiday and if this process is comparable to buying a holiday in the travel agency office.Diplomová práce obsahuje teoretické informace o cestovních kancelářích, internetovém marketingu, internetových reklamách a optimalizaci stránek. Tyto teoretické informace převádí do praxe pomocí popisu základních charakteristik konkrétní cestovní kanceláře Campanatour. Hlavní otázkou práce je to, jestli a jak moc je internet využíván při výběru a koupi dovolené. Práce podrobněji popisuje vzhled pobočky Campanatour a jejích katalogů, které jsou používány při výběru dovolené v kamenné prodejně. Dále se zaměřuje na vzhled internetových stránek a funkčnost internetového rezervačního systému, který je využíván při výběru dovolené na internetu. Práce je doplněna dvěma výzkumy. Jeden je prováděn pomocí návštěv v kamenných prodejách a na internetových stránkách dvou cestovních kanceláří a jedné cestovní agentury. Návštěvy jsou prováděny autorkou diplomové práce. Druhý výzkum probíhá formou dotazníku. Hlavním cílem výzkumů bylo zjistit, jestli a jak moc je internet využíván při výběru a koupi dovolené a dále to, jestli je tento způsob pořízování dovolené srovnatelný s koupí v kamenné prodejně

Valuable Secondary Habitats or Hazardous Ecological Traps? Environmental Risk Assessment of Minor and Trace Elements in Fly Ash Deposits across the Czech Republic

Deposits of coal combustion wastes, especially fly ash, are sources of environmental and health risks in industrial regions. Recently, fly ash deposits have been reported as habitat surrogates for some threatened arthropods in Central Europe. However, the potential environmental risks of fly ash have not yet been assessed in the region. We analysed concentrations of 19 minor and trace elements in 19 lignite combustion waste deposits in the Czech Republic. We assessed their environmental risks by comparison with the national and EU legislation limits, and with several commonly used indices. Over 50% of the samples exceeded the Czech national limits for As, Cu, V, or Zn, whilst only V exceeded the EU limits. For some studied elements, the high-risk indices were detected in several localities. Nevertheless, the measured water characteristics, the long-term presence of fly ash, previous leaching by acid rains, and the low amount of organic matter altogether can infer low biological availability of these elements. We presume the revealed high concentrations of some heavy metals at some studied sites can be harmful for some colonising species. Nevertheless, more ecotoxicological research on particular species is needed for final decision on their conservation potential for terrestrial and freshwater biota.info:eu-repo/semantics/publishedVersio

Bioaccumulation of chemical elements at post-industrial freshwater sites varies predictably between habitats, elements and taxa: A power law approach

Elevated environmental levels of elements originating from anthropogenic activities threaten natural communities and public health, as these elements can persist and bioaccumulate in the environment. However, their environmental risks and bioaccumulation patterns are often habitat-, species- and element-specific. We studied the bioaccumulation patterns of 11 elements in seven freshwater taxa in post-mining habitats in the Czech Republic, ranging from less polluted mining ponds to highly polluted fly ash lagoons. We found nonlinear, power-law relationships between the environmental and tissue concentrations of the elements, which may explain differences in bioaccumulation factors (BAF) reported in the literature. Tissue concentrations were driven by the environmental concentrations in non-essential elements (Al, As, Co, Cr, Ni, Pb and V), but this dependence was limited in essential elements (Cu, Mn, Se and Zn). Tissue concentrations of most elements were also more closely related to substrate than to water concentrations. Bioaccumulation was habitat specific in eight elements: stronger in mining ponds for Al and Pb, and stronger in fly ash lagoons for As, Cu, Mn, Pb, Se, V and Zn, although the differences were often minor. Bioaccumulation of some elements further increased in mineral-rich localities. Proximity to substrate, rather than trophic level, drove increased bioaccumulation levels across taxa. This highlights the importance of substrate as a pollutant reservoir in standing freshwaters and suggests that benthic taxa, such as molluscs (e.g., Physella) and other macroinvertebrates (e.g., Nepa), constitute good bioindicators. Despite the higher environmental risks in fly ash lagoons than in mining ponds, the observed ability of freshwater biota to sustain pollution supports the conservation potential of post-industrial sites. The power law approach used here to quantify and disentangle the effects of various bioaccumulation drivers may be helpful in additional contexts, increasing our ability to predict the effects of other contaminants and environmental hazards on biota.info:eu-repo/semantics/publishedVersio
