The Montreal Cognitive Assessment (MoCA) is one of the most common screening instruments for mild cognitive impairment. However, the standard MoCA is approximately two times longer to administer than the Mini-Mental State Examination. A total of 699 Czech and 175 American participants received the standard MoCA Czech and English versions and in the clinical part, a sample of 102 nondemented patients with Parkinson's disease (PD). We created a validated Czech short version (s-MoCA-CZ) from the original using item response theory. As expected, s-MoCA-CZ scores were highly correlated with the standard version (Pearson r = .94, p < .001). s-MoCA-CZ also had 80% classification accuracy in the differentiation of PD mild cognitive impairment from PD without impairment. The s-MoCA-CZ, a brief screening tool, is shorter to administer than the standard MoCA. It provides high-classification accuracy for PD mild cognitive impairment and is equivalent to that of the standard MoCA-CZ.

This paper investigates food waste at the consumer stage of the food chain. The authors conducted a questionnaire survey with 259 respondents to identify the key characteristics of food-wasting consumers and to suggest strategies to improve food-wasting behaviour. The results of the survey confirmed that the rate at which food is wasted depends on the age, economic status and education of the person managing food in a household, on the household's income per person and on total household income. Younger people, students, economically active people and people from higher-income households (both per household and per person) waste more, while pensioners waste much less than other groups. However, the sex of the food manager is not associated with food waste. These demographic characteristics should be considered when designing consumer education campaigns focussed on changing consumer motivation and behaviour. This paper also recommends other solutions tailored for specific demographic groups: Younger people and students may be influenced by the actions of opinion leaders within social networks, and technical devices enabling better food management could help them reduce waste. Supporting work-life balance, broadening the network of food delivery services and implementing corporate initiatives that support food waste prevention could help economically active people reduce their food waste.Additionally, offers of ready-to-eat food should be expanded for people with higher incomes.

This paper deals with similarity measures for categorical data in hierarchical clustering, which can deal with variables with more than two categories, and which aspire to replace the simple matching approach standardly used in this area. These similarity measures consider additional characteristics of a dataset, such as a frequency distribution of categories or the number of categories of a given variable. The paper recognizes two main aims. First, to compare and evaluate the selected similarity measures regarding the quality of produced clusters in hierarchical clustering. Second, to propose new similarity measures for nominal variables. All the examined similarity measures are compared regarding the quality of the produced clusters using the mean ranked scores of two internal evaluation coefficients. The analysis is performed on the generated datasets, and thus, it allows determining in which particular situations a certain similarity measure is recommended for use.

The present study determines the psychometric properties of the UDS-Cz and establishes normative values in the aging Czech population, which can be used in clinical settings.
