Abstract The adoption of digital technologies, along with current economic realities, has affected the entire process of visual news production. It has also influenced the traditional concept of photojournalism. As a result, news photographers face multiple new challenges. Although visual news material is becoming ever more important, news organizations have cut back on employment, leaving those few who remain employed with additional workload and responsibilities. Based on interviews with photojournalists and photo editors, this article examines the current state of photojournalism and editorial processes in three Central European countries – the Czech Republic, Poland and Slovakia. Findings indicate that photojournalists and photo editors face ongoing developments in the photographic medium that significantly affect their working practices and routines. At the same time, they must deal with increasing workload, new responsibilities, competition and the challenges of maintaining quality in the digital age.

Abstract Over the last few years, many European countries experienced a rapid growth of photovoltaic (PV) power plants. For example, more than 20, 000 new PV power plants were built in the Czech Republic. The high spatial and temporal variability of the solar resource and subsequent PV power plant production, poses new challenges for the reliability and predictability of the power grid system. In this paper, we analyse the most recent data on PV power plants built in the Czech Republic and Slovakia, with a focus on the spatial distribution of these installations. We have found that these power plants scarcely follow the solar resource potential and, apparently, other factors affect decisions for their location. Recent changes in the support schemes for solar applications also influence these patterns, with new installations mostly confined to built-up areas. These changes will require new tools to assess the appropriate locations of PV systems.

The municipalities development planning consists of two main streams—the spacial planning and the strategic planning—intents, objectives, and tactics of which are coordinated with various successes and outputs. The strategic planning has been implemented into the East European municipalities' management since the end of the 1990s. It had to respond to many oncoming circumstances. Economic, security, environmental, and other crises, both national and global, occurred. But the COVID-19 disease pandemic has brought wholly new challenges in the life management in the societies all over the world. The chapter intends to investigate how the value priorities within the municipalities strategic objectives changed during the pandemic, taking the Czech Republic (one of the European COVID-19 most affected countries) as an example.

Research background: The issue of green logistics is a very current topic not only from a scientific point of view but also from the point of view of business practice. The pressure to reduce negative environmental, social and economic impacts presents new challenges and pressures for companies, which will become more important in the coming years. This manuscript deals with green logistics tools applied in selected companies in the Czech Republic. The manuscript strictly focuses on the view of companies on green logistics and its tools, as well as on barriers and drivers for the implementation of green logistics. The aim of the article is to identify the attitude of selected companies in the Czech Republic to green logistics, to analyse barriers and drivers in the implementation of green logistics and to analyse the applied activities of green logistics and the reasons for their application. Purpose of the article: The main aim of the article is to identify the attitude of selected companies in the Czech Republic to green logistics and green logistics tools, to analyse barriers and drivers in the implementation of green logistics and to analyse the applied activities of green logistics and the reasons for their application. Finally, the results of this research are compared and discussed with the results of a study conducted in the Slovak Republic. Methods: To conduct the research, we have used computer-assisted web interviewing with selected Czech companies’ representatives. Findings & Value added: The results show that green logistics is very popular for companies. At the same time, barriers (most often financial) were identified, but also drivers and reasons for the implementation of green logistics tools. Comparing the results with the research conducted in the Slovak Republic, it can be stated that the results of both surveys were very similar, i.e. the location of the company in the Czech Republic or Slovakia does not affect the view of green logistics and its tools.

This paper analyses the conception of social risks in Czech social security law in the last three decades. The Czech Republic spends a large proportion of its revenue on welfare of its citizens, who rely on the state´s paternalistic care in return. Over time, benefits are increased and requirements are further softened. However, as we will see in chosen examples from healthcare, workers’ compensation, and additional savings schemes, Czech experts are reluctant to answer new challenges with reformed instruments. Rules are hardly adapted to current issues, because the government tends to rely on old solutions. The government is unable to find a constructive platform to negotiate crucial social reform laws with the opposition.

Compared with images of negatively stained single particle specimens, those obtained by cryo-electron microscopy have the following new features: (a) higher “signal” variability due to a higher variability of particle orientation; (b) reduced signal/noise ratio (S/N); (c) virtual absence of low-spatial-frequency information related to elastic scattering, due to the properties of the phase contrast transfer function (PCTF); and (d) reduced resolution due to the efforts of the microscopist to boost the PCTF at low spatial frequencies, in his attempt to obtain recognizable particle images.
