Normality tests for dependent data: large-sample and bootstrap approaches

The paper considers the problem of testing for normality of the one-dimensional marginal distribution of a strictly stationary and weakly dependent stochastic process. The possibility of using an autoregressive sieve bootstrap procedure to obtain critical values and P-values for normality tests is explored. The small-sample properties of a variety of tests are investigated in an extensive set of Monte Carlo experiments. The bootstrap version of the classical skewness--kurtosis test is shown to have the best overall performance in small samples

Higher prevalence of smoking and lower BMI, waist circumference, cholesterol and triacylglyceride levels in Prague's homeless compared to a majority of the Czech population

BACKGROUND: Homeless people have higher morbidity and mortality rates than the general population. Research has shown that cardiovascular disease is the leading cause of death in older homeless adults. This study was undertaken to describe the prevalence of cardiovascular risk factors in the homeless population in Prague. METHODS: Data was obtained from a cross-sectional study carried out in 2003. Body mass index (BMI), waist circumference (WC), total cholesterol (TC), triacylglycerides (TAG) and smoking habits were assessed. The homeless participants in the study were recruited from a homeless center run by a Prague charitable organization called Naděje ("Hope") and at Prague's main railway station. Most participants were assessed at the Naděje center (134 persons) while the rest were assessed at Prague's Bulovka University Hospital (67 persons). RESULTS: A total of 201 homeless (174 males and 27 females) aged 19 – 70 years were examined. Mean values of BMI, WC, TC and TAG in homeless men and women were within normal limits. Compared with the majority of the Czech population, the homeless had significantly lower mean levels of TC and TAG and lower BMI and WC values. When compared to the majority of the Czech population, the incidence of smoking among the homeless was significantly higher. Among smokers in both populations, no differences were found in the number of cigarettes smoked per day. CONCLUSION: Classical cardiovascular risk factors such as TC, TAG, BMI and WC, are significantly lower in Prague's homeless minority than in the majority of the Czech population. However, the prevalence of smoking is much higher in the homeless population

Metoda hodnocení environmentálního stresu a její aplikace v podmínkách Severozápadních Sudet

The results of research follow from new method designed at the Department of Geography (UJEP) and they document some analogical development trends and features of social and ecological burden (stress) and their correlation. It shows higher inertia of ecological subsystem conditioned by persistence of partial components of the subsystem. The ecological subsystem does not respect many changes and shift in social subsystem which is due to the existence of several significant macro-regional anthropogenic influences and impacts which exceed the boundary of model areas. Thus, an important role is assigned to geographical location of model areas and cross-border political and social effects influencing both human and natural components of the landscape. Next conclusion to be said is the correlation between population density and character of changes in social subsystem, while lower population intensifies the character of these changes

Macro-regional differentiation of the world: Authors’ concept and its application

This article is a continuation of the same authors’ study entitled ‘Concepts And Delimitation Of The World’s Macro-Regions’ prepared for the 1/2018 of this journal (Anděl et al. 2018). The main aim of the first part was an evaluation of the concepts and factors which have been used as a basis for the delimitation of the different macro-regions of the world. In this second part, the authors propose their own macro-regionalisation of the world – this is a combination of four concepts, with relatively different contents: those of De Blij and Muller (1997), Cole (1996), Huntington (1996) and Hampl (2009). This macro-regionalisation arises from sociocultural affiliation, economic interrelationships and territorial continuity. Along with the concept of the macro-regional differentiation of the world itself, we focus on evaluating the importance of the shaping of macro-regions, as well as assessing the positive and negative features of individual concepts and their influence on the macro-regional differentiation of the world

Concepts and delimitation of the worldʼs macro-regions

The authors focus on the current differentiation of the world and on its cognitive, application and educational frameworks and importance for the present. Macro-regional differentiation of the world has resulted from geographic concepts and it is a foundation for understanding the global development of society. This article evaluates the specific concepts and factors that form concepts of world macro-regions prepared by famous authors. It also presents a methodological approach for macro-regional forming of the world. After a theoretical and methodological introduction there is a discussion of the differentiation of the world entitled “Macroregional differentiation of the world - formation and application.ˮ The authors also present their conception of world differentiation and evaluation of the creation macro-regions and their positive and negative influence of the macro-regional differentiation of the world
