Fear of falling (FOF) is widely found in the elderly population and, regardless of its complex nature as a multicomponent construct, its related psychological variables have been overlooked as primary research topics. This article aims to examine the relationship between FOF, falls self efficacy, anxiety, balance, and perceived control over falling in a sample of older adults. A total of 100 subjects aged 60+ were asked about the presence of FOF, falls history, health, and functional status; they also completed the Falls Efficacy Scale (FES), the Geriatric Anxiety Inventory (GAI), the Perceived Control Over Falling Scale (PCOF), and the Performance-Oriented Assessment of Mobility and Balance (POMA-I). FOF was found to be associated with low falls self efficacy, low perceived control over falling, and reduced balance but not with anxiety. Conversely, a statistically significant association was found between GAI and FES, PCOF and POMA-I, and 47.1% of FOF was explained by two items from FES and GAI. FOF is influenced by variables that, though being commonly considered equivalent to FOF, do not fully explain it. A critical thought on the instruments used to evaluate FOF, is needed as well as additional studies to clarify the role of specific psychological variables. 相似文献

How do pre-kindergarteners spend their time? Gender,ethnicity, and income as predictors of experiences in pre-kindergarten classrooms 总被引:2,自引:0,他引:2

The current paper considers how children spend their time in state-funded pre-kindergarten programs and how time use relates to ethnicity, gender, and family income, based on the assumption that how time is spent in pre-kindergarten is relevant for the programs’ success in narrowing achievement gaps. Classroom observations of 2061 children in 652 pre-k programs in 11 states were analyzed. Findings indicated that the pre-kindergarten day was roughly equally divided among free choice, teacher-assigned activities, and meals/routines. Children spent much of their time in language/literacy, social studies, and art, and less time in math and gross motor activities. Much of the pre-k day was spent in ‘no coded learning activity.’ Children in classes with lower proportions of Latino and African American children and higher average income-to-need ratios were generally engaged in richer and more stimulating experiences. The child-level variables of ethnicity and income were generally unrelated to how children spent their time, above and beyond the effects of classroom-level ethnicity and income. There were generally small, but significant gender differences – always in the gender-stereotyped direction – in how time was spent, especially during free choice time. 相似文献

Painted glass magic lantern plates from the Museo Nazionale del Cinema, Torino (Italy), were studied using mid-infrared (mid-IR) fibre-optic reflectance spectroscopy (FORS), a non-invasive technique, to test its potential for the identification of the types of binding media used in the paints. Gum, oil and resin media were identified on the plates and the amounts of these media varied from place to place; the discovery of these media correlate well with the literature on magic lantern plate preparation and painting. The spectra collected are reported uncorrected and also with the fingerprint region corrected with the Kramers–Kronig correction, which corrects distorted peaks caused by specular reflections. 相似文献

The purpose of this study was to evaluate the traction characteristics of four different stud configurations on Fédération Internationale de Football Association (FIFA) 2-Star, third-generation artificial soccer turf. The investigated stud configurations were hard ground design, firm ground design, soft ground design, and an experimental prototype. The concept of this study combines performance, perception, biomechanical, and mechanical testing procedures. Twenty-five soccer players took part in the different testing procedures. Variables of this study were: running times, subjective rankings/ratings, ground reaction forces, and mechanical traction properties. Statistical discrimination between the four stud configurations was shown for performance, perception, and biomechanical testing (p < 0.05). Unsuited stud configurations for playing on artificial turf are characterized by less plain distributed and pronounced studs. 相似文献

The reduction of the administrative burden on businesses is an important governmental policy objective. Electronic government is presented as a promising reduction strategy in many countries. Underlying assumptions and mechanisms are hardly ever made explicit and scientific evidence of successful implementations is scarce. This paper presents an assessment of business-to-government systems in use in the Netherlands. Results show that organizational characteristics are the most influencing factors of perceived burden reduction and implementation effectiveness. Whereas perceived organizational benefits positively relate to the overall confirmation of the former system adoption decision. Surprisingly the quantitative, usage related characteristics do not present any statistical relevance. These findings help us understand existing differences in appreciation between business and governmental representatives on the successfulness of e-government projects in reducing the administrative burden on businesses. Furthermore, research results can help to enhance the effectiveness of e-government policy and measurement instruments. 相似文献
