张载是宋明理学的奠基人之一,其所创立的"关学"在中国思想史上具有深远影响,不仅如此,其思想在当今社会也有重要的借鉴意义。张载的"变化气质"学说指引着人们朝着全面发展的方向前进,其"民胞物与"思想为社会的和谐提供了有力的支撑,其完善的教育思想也为现代教育制度的构建提供理论指导。但是,理解张载的思想不能仅仅停留在理论层面,而要充分考虑到其现实的实践意义,也就是从当下出发去寻找其能够实现的生活化路径。  相似文献

Background.?Studies on the relationship between testosterone concentrations and blood pressure have yielded inconsistent results. Therefore, this study investigated the prospective association of total testosterone (TT) concentrations with risk of incident hypertension and blood pressure change in 1484 men aged 20–79 years.

Methods.?Data from the population-based Study of Health in Pomerania, Germany, were used. Serum TT concentrations, measured by chemiluminescent enzyme immunoassays, were categorised into age-specific quartiles. Generalised Estimating Equation (GEE) models, adjusted for age, waist circumference, physical activity, smoking and alcohol consumption were specified.

Results.?During a median follow-up time of 5.0 years, the prevalence of hypertension increased from 50.6% to 57.1%. TT concentrations were significantly lower in men with baseline and incident hypertension. Analyses revealed that men with baseline TT concentrations in the lowest quartile had an increased risk of incident hypertension (odds ratio (OR), 1.19 (95% CI, 1.10–1.28)) compared to men with higher TT concentrations. Furthermore, we found a significant inverse association of TT concentrations and blood pressure, showing that men with baseline TT concentrations in the lowest quartile showed the slightest change in systolic blood pressure (?6.01?mmHg), diastolic blood pressure (?2.11?mmHg) and pulse pressure (?3.98?mmHg). Sensitivity analyses in a subpopulation of men without antihypertensive medication confirmed these findings.

Conclusion.?These results show that low male TT concentrations are predictive of hypertension, suggesting TT as a potential biomarker of increased cardiovascular risk.  相似文献

Abstract

A quasi-experiment was undertaken to measure physiological characteristics of elderly women as they viewed different landscapes. Blood pressure and heart rate were monitored as elderly women living in a retirement centre viewed a natural landscape, a built landscape, and a control room with no view to the outside. Other characteristics of the individuals and the settings that have been shown to affect blood pressure and heart rate were controlled. The results indicated that, in all cases, viewing the natural landscape resulted in lower systolic and diastolic blood pressures and lower heart rates than those measured in the control room. Viewing the built landscape also had the general effect of lowering blood pressures and heart rates, but the effect was less consistent and the magnitude was smaller than that caused by the natural landscape. Lowering of blood pressure and heart rate have both been shown to be positively correlated with increased health and well-being, indicating the benefit of simply viewing a landscape. These results have important implications for design of housing for the elderly. Even if individuals are unable or unwilling to go outside, they can still benefit from seeing out into a landscape.  相似文献

The prevention and reduction of alcohol misuse is one of the Grand Challenges of Social Work. Addressing client needs beyond alcohol misuse can improve client outcomes. Driving under the influence program clients (N = 1,248) were screened for trauma events and posttraumatic stress disorder (PTSD). Results found that males more often reported having been assaulted with a weapon or that they caused injury to someone else. Females more often reported sexual assault and other unwanted sexual experience. About 26% overall screened positive for PTSD. Social workers need to be alert to various types of trauma and help clients identify the connection between trauma and alcohol misuse.  相似文献

文章系统地从法律的适用、归责原则、举证责任分配和免责事由等方面阐述了血液制品一般缺陷致人损害侵权中如何适用产品责任的问题。文中重点指出,此类侵权同时属于医疗行为侵权,因此在因果关系上应采用举证责任倒置;同时,根据举证责任的分配原则和《关于民事诉讼证据的若干规定》第7条,也兼具督促医院及时保留血液制品残液之目的,建议对血液制品存在缺陷实行举证责任倒置。  相似文献

为了了解公众对无偿献血相关知识的认知程度及行为态度,识别无偿献血机制面临的伦理困境,为完善无偿献血机制提供对策建议.作者以问卷调查为主,个人访谈为辅,对昆明市250名公众进行调查.结果显示:公众对无偿献血相关知识及政策的认知程度较低,仅有29.11%的被调查者参加过无偿献血;无偿献血机制面临宣传导向不正确、自愿献血困难重重、血站运行机制不合理等方面的伦理困境.要想走出困境,应该加强对无偿献血相关知识及政策的宣传,提高公众的认知程度;坚持公益性原则,理顺血站运行机制,消除公众信任危机;杜绝非自愿性献血,充分保障公众的自主权;完善无偿献血激励机制及保障机制,切实维护献血者合法权益.  相似文献

ABSTRACT

Richard Bates’s film Excision (2012) uses blood as a metaphor to interrogate how cultural constructions of femininity affect the development of adolescent girls. Contrary to other horror films, which frequently depict adolescent girls as examples of the ‘monstrous-feminine’, this film about a girl who decides to perform a lung transplant on her sister explores the horrors caused by restricting conceptualisations of feminine bodies and identities. The film’s focus on blood interrogates problematic ideological connotations between menstruation and sexual promiscuity, and questions the veracity of supposedly realistic representations of the female body in contemporary advertising. Its protagonist’s adaptation of the ‘mad scientist’ persona gradually turns her into a character resembling Frankenstein, whose monstrosity highlights her inability to either conform to or escape from femininity as a cultural construct. Teen horror, the film suggests, is not caused by blood and bodily matter, but by extra-textual stereotypes and gender inequality.  相似文献
