Previous studies indicated that blind and visually impaired people are a group with greater risk of falls. Postmenopausal changes significantly decrease physical efficiency and impair the body’s mechanisms for maintaining postural stability. In addition, the frequency of falls among women is much higher than in men. The aim of this study was to analyze the effect of sensorimotor exercise on changes in postural stability of visually impaired women over 50 years of age. Visually impaired women from group E showed a lower level of postural stability measured with EO compared to the healthy women. After completing the exercise, a more pronounced improvement in the level of postural stability was observed in group E. 相似文献

A mixed integer-valued autoregressive model of order one, based on the binomial and the generalized binomial thinning operator is introduced. Geometric marginal distribution is considered. Properties of the model are analysed, unknown parameters are estimated and some numerical results of the estimates are obtained. Finally, model is applied on two real data sets and compared to some relevant models. 相似文献

Like many other Central and Eastern European countries Croatia has passed through substantial political changes and transition
processes from state to liberal market economy in the last two decades. The next important step is accession to EU and NATO,
and public opinion about joining these associations is divided. The aim of this study is to investigate the predictive value
of subjective well-being measures in explaining attitudes of Croatian citizens toward accession to NATO and European Union.
In particular, the prognostic utility of SWB is tested over and above usefulness of basic socio-demographic variables in explaining
those political opinions. The research was conducted on a huge and representative sample (N = 4,000) of Croatian citizens in the spring of 2009. As a measure of subjective well-being, Croatian version of International
Well-Being Index (IWI; Cummins in International Wellbeing Index, Version 2 [online]. Available from: , 2002) was used. IWI includes National and Personal Well-Being scales where each scale consists of several personal or national
well-being domains. Socio-demographic variables used in this survey were gender, age, and level of education. Hierarchical
logistic regression was applied to test the unique contribution of National and Personal well-being domains in predicting
attitudes toward accession. The results show that National well-being index is useful in predicting attitudes toward accession
of Croatia to EU and NATO, and has an even higher predictive value than basic socio-demographic variables. National well-being
domains that significantly improve prediction were satisfaction with government and satisfaction with national economic situation.
Higher satisfaction with national government is related to support of accession to both alliances, whereas higher satisfaction
with national economy is associated solely with supporting the EU membership. The personal well-being index and belonging
domains were not useful in this political attitude prediction. Possible theoretical explanation of observed relations between
NWI and political opinion were further discussed. 相似文献

The idea of Europe was radically transformed after the accomplishment of the idea of European unification. The European Union (EU) and Europe at the beginning of the twenty-first century were defined by a broad common ideology that consists of ideologies such as antinationalism, social democracy, pacificism and environmentalism. These ideologies are presented by pro-EU scholars and politicians as ideologies rooted in European history and parts of European identity and as being mostly absent in the American policies. The emergence of EU ideology is traced in the relaunch of European integration in the mid-1980s and in Delors’ conflict with Thatcher. It is argued that the emergence of EU ideology is the result of two long-term historical developments: the deepening and enlargement of European integration; and the changing relations between the USA and Europe. It is concluded that the emergence of EU ideology resembles the emergence of nationalism and national ideologies. 相似文献

In this article, we first introduce an alternative way for construction of the generalized binomial thinning operator with dependent counting series. Some properties of this thinning operator are derived and discussed. Then, by using this thinning operator, we introduce an integer-valued time-series model with geometric marginals. Some conditional and unconditional properties of this model are derived and discussed. Some estimation methods are considered and for some of them, asymptotic properties of the obtained estimates are derived. Performances of the estimates are discussed through some simulations. Finally, a real data example is considered and the goodness-of-fit of this model is compared with the models based on the binomial, negative binomial, and dependent binomial thinning operators. 相似文献

The main theme considered in this article is an integer-valued thinning operator with both positive and negative values, its properties, and a new time series with skew discrete Laplace marginals. Some properties of this model are discussed, as well as estimators of unknown parameters, similarities and differences with some other existing models, applications in real-life situations, and identification and approximation of latent processes affecting the concerning process. 相似文献
