Content available remote Sway ratio - a new measure for quantifying postural stability
In the search of a reliable postural stability index, two sway time series: the center-of-mass (COM) and the center-of-foot pressure (COP) were recorded simultaneously in elderly subjects standing quiet with eyes open and with eyes closed. From a battery of commonly use sway measures, only the anteroposterior COM and the COP path lengths proved their high sensitivity and discriminative power to the imposed vision conditions. Based upon these indices, a new measure ? sway ratio (SR) ? was computed, as the COP-to-COM path length ratio. The measure can easily distinguish vision vs. no vision in the elderly. The SR can be successfully accessed base upon the COP signal only. In contrast to traditional sway indices, the SR as a relative measure is insensitive to the length of sampled record and to the signal sampling frequency. Its magnitude can be interpreted as an average amount of balance controlling motor activity that coincides with a unit COM displacement. The SR is recommended as a reliable measure that allows for assessment of postural stability.
Empirical findings go to show that accommodative modes of coping with changes as also of everyday problems in aging are more adaptable and more effective. The aim of this study has been to extend the theoretical construct of accommodative flexibility to conditions of practical geronto-psychology. We verified whether it is possible, with the aid of psycho-educational intervention, to purposively stimulate accommodative flexible attitudes in the elderly when dealing with everyday problems. The study presents the first results from an application of the original intervening program reinforcing the accommodative flexibility in the behavior of the elderly, as designed at the Institute of Experimental Psychology.
The paper is of an informative character and presents a unique phenomenon, namely the Bealtaine Festival. In the first part, the authoress cites demography of Irish society and refers to the forecasts concerning the ageing of the world's population. The second part of the article entitled Bealtaine - general information covers the key organizational assumptions of the Festival. Furthermore, the authoress mentions some of the projects and events that took place during the 2006 and 2007 Festivals. Next part of the article entitled Bealtaine 2008 is devoted to some basic information about the 2008 Festival. Given the nationwide nature of the Bealtaine Festival, the paper does not cover all of the events taking place there limiting the description to two unique projects. Moreover, the authoress notes that although the Bealtaine might have been a pioneering venture, the idea of such events had already been put into practice in Wales and the Netherlands. Finally, a brief summary stresses the importance of the Festival for socio-cultural life in the Republic of Ireland.
Studies related to well-being of older people have been carried out in the past with two types of variables: those reflecting socioeconomic factors, and those referring to psychological and psycho-social variables. Since one of the important psychological variables - goal-achievement strategies - can be different in older age, the relationships between strategy use in older people and their well-being are valuable to explore. In this research the authors used the model of goal-achievement strategies (selection, optimization and compensation) in elderly proposed by Baltes and Baltes (1990). The short version of the SOC questionnaire (Selection, Optimization and Compensation; Baltes et al., 1999), the Global happiness item and the Global satisfaction item as measures of two dimensions of subjective well-being were individually administered to 355 people 65-96 years old in Western Croatia. The results indicate that in goal-achievement, older people with higher level of well-being use more frequently strategies of optimization and compensation, while those with lower level of well-being use the strategy of selection more frequently.
The COVID-19 pandemic is often associated with the phrase coronavirus crisis. A crisis can be defined by three characteristics: a specific, unexpected event that creates a high level of uncertainty, and involves a (perceived) threat to important goals (Seeger et al., 1998). The aim of this research is to examine more deeply how the "coronavirus crisis" manifested itself at an individual level in the most vulnerable groups of the population, the elderly (Centers for Disease Control and Prevention, 2020; Public Health Authority of the Slovak Republic, 2020), during the first wave of the disease in Slovakia. In particular, the aim is to examine which specific stressors are perceived as stressful (which are sources of stress) and which coping strategies are preferred by the elderly, as well as how these sources of stress and coping strategies relate to the demographic characteristics of the elderly (both in gender and age). Using the snowball method, 607 people over the age of 62 from all over Slovakia participated in the online research. The findings point to the need to perceive the stress experience of each elderly person as unique. Research findings can be useful for the elderly themselves, but also for those who work with elderly and/or implement interventions.
