Given the high costs of lactation and the importance of milk for pup growth and survival in pinnipeds, nursing behaviour directed by a lactating female towards another adult is unexpected. Here, details were noted of a nursing interaction that occurred between two Cape fur seal Arctocephalus pusillus pusillus adults. After discussing the event in the light of various hypotheses that have been previously proposed to explain uncharacteristic nursing behaviour in pinnipeds, a mother–son relationship between the interacting pair was considered to be the most likely explanation. 相似文献

In recent years, Konosirus punctatus has accounted for a large portion in catch composition and become important economic species in the South Yellow Sea. However, the distribution of K. punctatus early life stages is still poorly understood. In this study, generalized additive models with Tweedie distribution were used to analyze the relationships between K. punctatus ichthyoplankton and environmental factors(longitude and latitude, sea surface temperature(SST), sea surface salinity(SSS) and depth), and predict distribution K. punctatus spawning ground and nursing ground, based on samplings collected in 6 months during 2014–2017. The results showed that K. punctatus' spawning ground were mainly distributed in central and north study area(from 33.0°N to 37.0°N).By comparison, the nursing ground shifted southward, which were approximately located along central and south coast of study area(from 31.7°N to 35.5°N). The optimal models identified that suitable SST, SSS and depth for eggs were 19–26°C, 25–30 and 9–23 m, respectively. The suitable SSS for larvae were 29–31. The K. punctatus spawning habit might have changed in the past decades, which was a response to increasing SST and fishing pressure. That needs to be proved in further study. The study provides references of conservation and exploitation for K. punctatus. 相似文献

在同样气候条件下,通过对50例有条件可以获得家庭护理的抑郁症患者,给家属作健康教育,指导家庭护理和50例无条件获家庭护理的患者数据进行分析得出：气候与抑郁症有显著关系,1月、2月份最寒冷,日短夜长,11月、3月份气温不稳定,并时常绵绵细雨,日照少,具有诱发抑郁症的气象因素,而恰当的家庭护理可以有效缓解抑郁症的复发或减轻症状;用SPSS软件包进行检验,差异有显著性（P〈0.05）。 相似文献

中国城市养老院的空间分布特征及其分异成因 总被引：1，自引：0，他引：1
中国正在快速步入老龄化社会,老年人的养老问题已经成为当今社会密切关注的焦点。养老院是解决中国养老问题的有效办法。因此,分析中国城市养老院的空间分布特征以及探索城市之间养老院数量差异的成因具有重要的现实意义。本文利用网络爬虫技术获取了2019年中国285个城市的养老院数量,并进行了地图化展示,然后从空间分异性视角出发,运用地理探测器方法对城市养老院数量的社会经济影响因素进行分析。结果表明：① 中国城市养老院数量的空间分布与城市老年人口分布非常相似。② 地理探测器方法的因子探测结果显示,老年人口数量、经济发展水平、公共财政支出、养老保险参保人数和公园绿地面积是影响城市养老院数量的主要因素。其中,城市财政支出能力和经济发展水平对于养老院的建设至关重要。③ 交互因子探测分析结果显示,5个影响因素的两两交互作用均大于单个因素的作用,说明城市养老院数量的空间分布是受多种因素共同作用的结果。其中,老年人口与其他4个变量的交互作用最强,说明老年人口和其他因素结合对城市养老院数量空间分布来说是最主要的影响因素。 相似文献

(Re)thinking the dynamics between healthcare and place: therapeutic geographies in treatment and care practices 总被引：3，自引：0，他引：3
Gavin J Andrews 《Area》2004,36(3):307-318
Although the concept of therapeutic landscapes has assisted health geographers to explore the intimate connections between well-being and place, arguably, after a decade of applications, the common interpretations and assumptions of commentators should be reviewed. Based on theoretical insights from psychoanalytic geographies and geographies of nursing, this paper makes two observations. First, that landscape has been almost exclusively interpreted in a physical sense with co-presence being a necessary condition. In turn, this assumption has led to the neglect of non-physical (imagined) places. Second, that therapeutic effects have been interpreted as experiences attained outside of clinical practices. Hence, healthcare workers and their direct treatments and care have also been neglected. To explore these omissions together, an interview survey of complementary therapists investigates the many ways in which imagined places are constructed and manipulated in therapy sessions. Arguably, beyond this example, extending the therapeutic landscape concept to both physical and non-physical features of treatments could provide fresh insights into the dynamics between healthcare and place. In disciplinary terms, the benefits are twofold. Whilst it could help develop a critical tradition in health geography, perhaps ironically, it could also provide a stronger disciplinary connection between qualitative health geography, various forms of medicine and their research traditions. 相似文献

鲈鱼(Lateolabraxjaponicus)又称花鲈、寨花,是我国广大沿海地区土池和网箱养殖的优良品种之一,具有广温、广盐、生长快、肉质鲜美等优良品质。 鲈鱼人工育苗的关键在于优良亲本的获得。实践证明,在鲈鱼的繁殖季节,很难捕获性腺发育良好(期、期)的野生亲鱼,使得利用海捕亲鱼进行人工授精培育苗种的工作很难实行。培育人工亲鱼的方法虽然较为困难,但势在必行。我国南方沿海由于网箱养殖条件优越,无需越冬,人工养殖4～5a可以成为优质的亲鱼。而北方尤其是山东沿海,由于存在着越冬的障碍,致使养殖业户难以坚持养殖数年,以培育出鲈鱼亲鱼。… 相似文献

目的:探讨护理干预在冠状动脉CTA(CCTA)检查中的临床应用价值。资料与方法:将准备做CCTA检查的80例患者,随机分为对照组和护理干预组(n=40例)。对照组:口服倍他乐克,降低心率,不做其他干预。护理干预组:采取一系列护理干预措施,有效降低患者心率(HR<70bpm)及控制心率稳定。结果:对照组,检查成功25例,15例失败,成功率为62.50%(25/40),成功25例患者中图像质量优13例,良好5例,基本满足诊断7例,优良率为72%(18/25);护理干预组,检查成功38例,失败2例,成功率为95%(38/40),成功38例患者中图像质量优30例,良好5例,基本满足诊断3例,优良率为92.11%(35/38)。2组检查成功率具有明显统计学差异(P<0.01),图像质量优良率亦有统计学意义(P<0.05)。结论:做CCTA检查前实施护理干预能明显提高检查成功率及保证图像质量优良率。 相似文献
