The study proposed to identify balance strategies used by younger and older adults during gait under proprioceptive, visual, and simultaneous proprioceptive-visual challenges. Participants ambulated under 4 conditions: consistent, noncompliant surface; inconsistent, compliant surface (C); consistent, noncompliant surface with vision obscured (NCVO); and inconsistent, compliant surface with vision obscured (CVO). Balance adaptations were measured as changes in gait velocity, cadence, and gait-stability ratio (GSR). Participants were 5 younger (mean age = 27.2) and 5 older (mean age = 68) healthy adults. Significant age differences were found for GSR (p = .03) on all surfaces. Older adults adopted a more stable gait pattern than younger adults regardless of the challenge presented by surface. Significant condition differences were found for velocity (p < .001) and cadence (p = .001). All participants exhibited significantly decreased velocity and increased cadence on surfaces C and CVO. Gait speed and cadence did not significantly change in NCVO. Younger and older adults exhibited similar adaptive balance strategies, slowing and increasing steps/s, under proprioceptive and proprioceptive-visual challenges to dynamic balance. 相似文献

In order to estimate the demographic impact of IUD, there is a need for estimating IUD retention rates beyond the period of actual observation. This article describes a mixed exponential function for this purpose. With this function of IUD retention, it is possible to estimate the “life expectancy” and “half-life” of an IUD. Another important concept is the “cut-off date”, introduced in estimating the “life expectancy” because in practice no IUD will be worn by a woman forever. 相似文献

While there are several measures of living environment restrictiveness, none has used the youth perspective in conceptualizing and operationalizing restrictiveness. The purpose of this qualitative study was to obtain the perspectives of child welfare involved youth who have lived in out-of-home care. Using focus group methodology, 40 youth were asked to define restriction and give examples of how it is operationalized in practice. Youth defined restriction as “rules”. The rules were about what youth can do, where they can go, who they can be with and how and with whom they can communicate. These rules were primarily characterized as inconsistent, arbitrary, non-individualized and developmentally inappropriate, although some characterized them as beneficial in the long term. Rules were mostly attributed to adult need for power and avoidance of legal responsibility for the youths. Typical feelings about the rules were anger, resentment, feeling labeled, isolated and stigmatized. Relationships influenced perceptions: within a positive relationship, youth understood and tolerated the rules that limited independence. The perception of what were normal restrictions for other youth not in out-of-home care was another influencing factor. These findings are examined in light of cognitive and affective development in adolescence. Recommendations for improving the measurement of living environment restrictiveness as well as enhancing child welfare services are proposed. 相似文献

Climate change and environmental issues have been increasingly in the forefront of the media and government agendas. However, despite much discussion and fanfare, little has been done in the way of serious commitment and clear course of actions since the adoption of the UN Framework Convention on Climate Change in 1992 to bring carbon emissions to sustainable levels. To tackle the immensity of the climate change challenge, a paradigm shift in understanding is necessary to balance the course of global human development with energy demand and consumption patterns. Accounting for over 40% of global energy demand and more than 30% of greenhouse gas emissions, the building sector offers the greatest mitigation potential for reducing carbon emissions in both the short and long term, with positive implications for a range of associated sectors and industries. Promoting behavioral change among end-users for reduced energy consumption as well as encouraging the building industry to embrace sustainable design, low-carbon construction practices and materials, and renewable technologies, is fundamental to mitigating the impact of the built environment on planetary biospheres and preserving quality of life for generations to come. This paper starts by drawing attention to the building sector and related EU policy, outlining the challenges and opportunities for reducing energy consumption and carbon emission levels. Such policy provides the essential framework to engage stakeholders and allow supporting factors to foster progress in the sector. The paper contends that information on climate change has not led to significant improvements in meeting global targets and that what is needed is behavioral change among individuals and society as a whole. On the basis of research project experiences and literature review, it puts forth and explores five key elements contributing to behavioral change for reduced energy consumption and lower carbon emissions in the building sector, focused on: information and education; financial incentives and energy services; modern technologies and sustainable design; social and community norms; and biophilia (contact with the natural environment). The paper suggests opportunities for further research and concludes with recommendations for policy-makers and related stakeholders. 相似文献

Corporate Trainers experience many organizational challenges that require new skills. This qualitative study sought to determine the challenges faced by South African Education Training and Development university students employed as trainers in corporate roles. Findings suggest that trainers require contextual and generic soft skills to meet the requirements of their jobs and that the term trainer embraces a variety of roles of different focus and different status. While there appear to be a common set of problems facing trainers irrespective of location, the interventionist skills and employment policies of the South African government have an important influence on activity in the organization. 相似文献

This study identified a constellation of psychosocial problems reported by older Asian American adolescents that was different from their Caucasian peers. When compared to 386 Caucasian American adolescents from the same community, Asian American students performed better academically and reported fewer delinquent behaviors. However, these Asian American youth reported higher levels of depressive symptomatology, withdrawn behavior, and social problems. They also perceived themselves more poorly and were more dissatisfied with their social support. These differences highlight the unique mental health needs of older Asian American youth. Practice recommendations are made that consider traditional Asian values and the role that family members can play in the development of effective treatment plans. 相似文献

BackgroundAlthough midwifery literature suggests that woman-centred care can improve the birthing experiences of women and birth outcomes for women and babies, recent research has identified challenges in supporting socially disadvantaged women to engage in decision-making regarding care options in order to attain a sense of control within their maternity care encounters.ObjectiveThe objective of this paper is to provide an understanding of the issues that affect the socially disadvantaged woman's ability to actively engage in decision-making processes relevant to her care.Research designThe qualitative approach known as Interpretative Phenomenological Analysis was used to gain an understanding of maternity care encounters as experienced by each of the following cohorts: socially disadvantaged women, registered midwives and student midwives. This paper focuses specifically on data from participating socially disadvantaged women that relate to the elements of woman-centred care-choice and control and their understandings of capacity to engage in their maternity care encounters.FindingsSocially disadvantaged women participants did not feel safe to engage in discussions regarding choice or to seek control within their maternity care encounters. Situations such as inadequate contextualised information, perceived risks in not conforming to routine procedures, and the actions and reactions of midwives when these women did seek choice or control resulted in a silent compliance. This response was interpreted as a consequence of women's decisions to accept responsibility for their baby's wellbeing by delegating health care decision-making to the health care professional.ConclusionThis research found that socially disadvantaged women want to engage in their care. However without adequate information and facilitation of choice by midwives, they believe they are outsiders to the maternity care culture and decision-making processes. Consequently, they delegate responsibility for maternity care choices to those who do belong; midwives. These findings suggest that midwives need to better communicate a valuing of the woman's participation in decision-making processes and to work with women so they do have a sense of belonging within the maternity care environment. Midwives need to ensure that socially disadvantaged women do feel safe about having a voice regarding their choices and find ways to give them a sense of control within their maternity care encounters. 相似文献

During the First Maroon War, violent battles between Maroons and British colonists were frequent and violent. How then, after the peace treaties, did former enemies negotiate their new positions as allies? How did colonists accept this new status quo while balancing it with racial beliefs of the era? This article examines Maroon and colonist efforts to progress in a physically difficult and socially charged environment while living side-by-side with a large enslaved population. Ultimately, some influential planters, as opposed to poorer settlers, came to recognise the mutual benefits this uneasy peace provided. That is not to say these colonists were not fearful of the Maroons but that they recognised the usefulness of the Maroon communities. 相似文献

In order to study the relationships between work satisfaction and mental health in a group known to be at risk for psychological distress, university students who were somewhat older than usual (n=568, average age 24 years) provided infomiation by questionnaire about their satisfactions from study and paid work, and their level of psychological distress. The measure of study satisfaction was a modified form of Warr et al.'s (1979) Job Satisfaction Scale, and had good reliability. Study satisfaction waslower for undergraduate than for postgraduate students, due to lack of clearly defined identity, less supportive relations with fellow-students and teaching staff, and financial hardship. For all subjects the availability of teacher support predicted study satisfaction, and study satisfaction had a major influence on the students' psychologcal well-being. 相似文献
