Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults.  相似文献   

Delinking rhetorics of neoliberalism: An analysis of South American leftist presidents’ speeches     

Adriana Angel  Luis Miguel López-Londoño 《Journal of International and Intercultural Communication》2019,12(1):43-62

We analyze the so-called Socialism of the twenty-first century in which nine South American governments turned to the left over the last 15 years. This South American socialist turn is seen as a delinking from the logics of dependency and pure neoliberalism. To explore the rhetorics that underlie this delinking process, we conducted both a macroanalysis and an intradiscursive rhetorical analysis of the inauguration and most significant speeches of all of the leftist South American presidents elected after 1999. We claim that a common critique of neoliberalism underlies the South American presidents’ speeches, which manifests through specific rhetorics concerning participatory democracy, social inclusion, and environmental protection. When they became transnational, these delinking rhetorics crafted a decolonial critique that calls for more indigenous models of development.  相似文献

身在佛门心系红尘——妙玉情感矛盾透析     

穆乃堂 《阜阳师范学院学报(社会科学版)》2001,(4):35-37

自动走向佛门是精神解脱,被动走向佛门是精神禁锢。妙玉“身在佛门,心系红尘”,其情感矛盾的变化折射出她人生思想的变化历程,反映了佛性与人性在其心中地位的转换。人性的复醒,使妙玉对红尘生活的向往与日俱增,她背负着沉重的精神枷锁,步履艰难地迈向世俗世界。妙玉在人性与佛性的门缝中呻吟、挣扎,最终被佛性与人性两扇大门挤扁了,磨碎了。  相似文献
