The aim of our study is to identify and evaluate the impact of rules changes in 2010 on success of two-point shooting and three-point shooting between selected Czech and foreign players taking part in National Basketball League- top male competition in the Czech Republic who have met with our specifi ed conditions in examined seasons 2009/10 and 2010/11. There are following methods used in the very research in the empirical part: Student’s paired t-test, Two-sample F-test, Student’s unpaired t-test of equality of variances and Size of eff ect. The results of these tests has statistically confi rmed our hypotheses H1 and H2 – it means decreasing of two-point shooting success in season 2010/11 for all examined players and reducing of success at three-point throws between players with Czech nationality. On the contrary, it has not confi rmed the hypothesis H3, thus increasing of three-point shooting success in season 2010/11 between foreign players. Substantively, we consider as an essential result the 20.1% negative impact of the rules changes on success of three-point shooting for players of Czech nationality.

This paper analyzes the impact of Union budget on NSE’s CNX NIFTY Index. The impact is measured in terms of daily average returns and volatility over the short term, medium term and long term period in pre and post budget period. The data has been collected for five budget periods from 2011 to 2015. The statistical tools used are paired T-test and F-test. Paired T-test is conducted on average returns and F-test is conducted on variances over the period i.e., 3, 10 and 30 days in pre and post budget period. The maximum impact of budget is seen in short term then it gradually decreases in medium term and finally diminishes in the long term. The implication of this paper is that the investor should fear from investing in the stock market around the budget period.

The Impact

In this study we investigated the microbial contamination of 126 samples of photographic and cinematographic materials from 10 archival funds in the Czech Republic. Microorganisms were isolated from the light-sensitive layer by swabbing it with a polyurethane sponge. Microbial isolates were identified by MALDI-TOF MS (bacteria) or by phenotype testing and microscopy (fungi). Bacterial contamination was more abundant and more diverse than fungal contamination, and both were significantly associated with archives. The most frequently isolated fungal genera were Cladosporium, Eurotium, Penicillium, Aspergillus and Alternaria. The most frequently isolated bacteria were Gram-positive genera such as Staphylococcus, Micrococcus, Kocuria, Streptococcus and Bacillus. This bacterial and fungal diversity suggests that air is the main vehicle of contamination. We also analysed the impact of the type of material used for the carrier (paper, baryta paper, cellulose acetate and nitrate or glass) or the light-sensitive layer (albumen, gelatine, collodion and other) on the level and diversity of microbial contamination. Carriers such as polyester and cellulose nitrate may have a negative impact on bacterial contamination, while paper and baryta paper may have a partially positive impact on both fungal and bacterial contamination.

Environmental degradation is one of the most significant problems of the globalized world. This paper explores the impact of institutional development and human capital on CO2 emissions in 11 EU transition economies over the period of 2000–2018 through co-integration analysis. The co-integration analysis revealed that human capital negatively affected CO2 emissions in Croatia, the Czech Republic, Hungary, and Slovenia, and that institutions had a negative impact on CO2 emissions in the Czech Republic. However, both institutions and human capital positively affected CO2 emissions in Latvia and Lithuania.

The Impact

The objective of this study is to investigate the role of internal factors in generating financial performance of firms in the Czech Republic. The paper examines the impact of firm specific factors on company financial performance of 974 firms in the Czech Republic over the period 2005 to 2008, using data in the Albertina database. Pooled and panel cross-sectional time series techniques are used for the data analysis. Return on Assets (ROA) is the dependent variable of the model and eight firm specific factors are introduced as the explanatory variables. Using Return on Assets as the dependent variable, it is established that the firm size, sales growth and capital turnover are having significant positive impact on financial performance of firms. At the same time, debt ratio and inventory reflect significant negative impact on financial performance of firms. Overall explanatory powers of the two models are low and further research is necessary to increase the statistical power of the model. The results from the present study may be very encouraging and useful for managers as well as investors to plan investment and operational activities to achieve profitability objectives more efficiently and effectively. The findings have important managerial implications.

The Impact

Global and regional biodiversity loss is caused by several drivers including urban development, land use intensification, overexploitation of natural resources, environmental pollution, and climate change. The main aim of our study was to adapt the GLOBIO3 model to the conditions of the Czech Republic (CR) to assess loss of naturalness and biodiversity vulnerability at the habitat level on a detailed scale across the entire CR. An additional aim was to assess the main drivers affecting the biodiversity of habitat types. The GLOBIO3 model was adapted to CZ-GLOBIO by adapting global to local scales and using habitat quality and naturalness data instead of species occurrence data. The total mean species abundance (MSA) index of habitat quality, calculated from the spatial overlay of the four MSA indicators by our new equation, reached the value 0.62. The total value of MSA for natural and near-natural habitats was found to be affected mainly by infrastructure development and fragmentation. Simultaneously, intensity of land use change and atmospheric nitrogen deposition contributed primarily to the low total value of MSA for distant natural habitats. The CZ-GLOBIO model can be an important tool in political decision making to reduce the impact of the main drivers on habitat biodiversity in the CR.

The aim of the presented article is to evaluate the impact of climate change on the sugar content of grapes in the Czech Republic during the period 2000–2019 through selected indicators on the basis of available secondary sources. Attention is focused on the developments in both the main wine-growing regions of Moravia and Bohemia. In the field of viticulture and wine-growing, the sugar content of grapes, as a basic parameter for the classification of wines, plays an important role. In the Czech Republic, the average sugar content of grapes has had a constantly growing trend. This trend is evident both in the wine-growing region of Bohemia and in the wine-growing region of Moravia. The impact of climate change, especially the gradual increase of average temperatures in the growing season, cannot be overlooked. It greatly affects, among other things, the sugar content of grapes. Calculations according to the Huglin Index and the Winkler Index were used to determine the relationship between climate and sugar content. These indexes summarize the course of temperatures during the entire vegetation period into a single numerical value. The results show that both indexes describe the effect of air temperature on sugar content in both wine regions of the Czech Republic in a statistically significant way. The Huglin Index shows a higher correlation rate. The Winkler Index proved to be less suitable for both areas. Alternatively, the Winkler Index calculated for a shorter growing season was tested, which showed a higher degree of correlation with sugar content, approaching the significance of the Huglin Index.

Inflammatory Bowel

Background: Several previous studies reported the negative impact of inflammatory bowel disease (IBD) on reproductive plans and fertility rate. The aim of our study was to investigate, for the first time, reproductive attitudes and fertility rate among Czech patients with IBD. Methods: Between March and August 2019, consecutive patients with IBD from 22 centres across the Czech Republic responded anonymously to a predefined questionnaire focused on the patients’ demographics, details of IBD and treatment, gynaecological/urological history, reproductive issues and patients’ knowledge on this topic. Results: The questionnaire was filled in by 798 patients (526 women; median age 34 years, 66% with Crohn’s disease). Of these, 58% of the females and 47.1% of the males already had ≥ 1 child (median 2 children). Women with IBD were significantly more worried about infertility (55.5% versus 22.4%), had more limitations in their sexual life (53.2% vs. 26.8%) and more frequently changed their earlier reproductive plans (27.6% versus 11.0%) than the males (p < 0.0001). The total fertility rate in female IBD patients was lower compared to the general population with 1.004 live births/IBD woman versus 1.69 live births/woman in the Czech population. The pattern of decreased fertility was observed in all age-specific categories. Of the childless patients, 14% of the women and 18.1% of the men were voluntarily childless. Approximately one-half of them indicated their IBD to be the primary cause. Conclusions: IBD seems to have a negative impact on patients’ reproductive plans and attitudes. The fertility rate in Czech IBD female patients was decreased compared to the general population in this study.

The Impact

Memories of wrongdoings are often viewed as an obstacle to reconciliation in divided societies. Is it due to the past or the present politics of the past? To examine the dilemma of essentialism versus presentism, this article investigates the impact of transitional justice on memories of wrongdoing. It theorizes that using different transitional justice strategies to deal with the same wrongdoing shapes memories in different ways. The theory is tested via vignette-based surveys in the Czech Republic, Hungary and Poland, which adopted distinct lustration laws. The results show that wrongdoing is viewed through lustration laws, reflecting present power constellations, not history.

SummaryOnly a few studies have assessed the predation risk on artificially marked nests, or have examined ways of marking nests to avoid destruction by machinery. Until now, however, neither type of study has directly addressed this apparent trade-off experimentally. The impact of marking the nests of Northern Lapwing Vanellus vanellus with thin 2 m-long conspicuous bamboo poles with the top end highlighted with reflective red or orange spray has been tested for three years in two breeding areas of waders in the Czech Republic. A total of 52 pairs of nests on agricultural land, with each pair consisting of one marked nest and one unmarked reference counterpart nest, were monitored for 2004 nest-days until hatching, agricultural operations or failure. The results proved that marking itself does not result in increased nest predation. The nests found in the early incubation stage were under higher threat of depredation, irrespective of the presence of marking. Our results show that it is possible to find a finely-tuned trade-off in nest marking of ground-nesting birds between risk of damage by agricultural machinery and risk of increased nest predation. Our positive experience with Northern Lapwing, and episodically with three other wader species in the Czech Republic, suggests that this direct nest protection could be used effectively for a wider variety of ground-nesting birds.
