浅析高校图书馆报纸的人文管理

报纸是一种形式普及、内容广泛、报道及时的信息资源,是研究某一地区、某一国家,特定历史时期社会状态不可或缺的文献资料。对报纸实行人文管理不仅仅是高校图书馆提高自身水平的要求,也是报纸自身特点的要求,更是满足广大师生对信息收集的要求。如何针对性地满足读者的各种信息需求,加大对报纸人文管理和利用,是高校图书馆最根本的职责。     

中医院校教职工对医养结合养老模式认知情况的调查与思考

目的 了解中医院校教职工对医养结合养老模式的认可程度和需求,探索促进医养结合养老模式发展的途径。方法 对湖南省某中医药大学及附属医院教职工进行问卷调查。结果 共收回有效问卷340份,在选择养老院时,被调查对象偏重于选择社区卫生服务中心内设养老机构,了解医养结合的途径主要是网络与电视,对医养结合的养老模式比较认可,但是存在认知度不高、对收费标准不满意等问题。结论 医养结合机构需要加强宣传力度;政府发挥宏观调控职能;调动社会力量积极性、增加医养结合供给;医养结合机构提高医疗和养老服务的能力和水平;加强专业人才队伍建设,发挥中医药在养老服务中的作用。     

高效液相色谱法测定银杏叶保健饮料中槲皮素的含量

采用高效液相色谱法测定银杏叶保健饮料中槲皮素的含量,用YWG-C18(150 mm×4.6 mm i.d, 10 μm)色谱柱分离,以V(甲醇):V(磷酸)=55:45(其中φ(磷酸)＝0.004)作流动相,于254 nm波长处检测. 结果表明,样品添加对照品的回收率在93.5%～101.0%之间,变异系数为3.38%,定量测定下限为0.32 mg/L.     

When and why do smallmouth bass abandon their broods? The effects of brood and parental characteristics

Abstract Variation in brood abandonment was explored by conducting partial brood removals from smallmouth bass, Micropterus dolomieu Lacepède, nests in two north temperate lakes. In both lakes, percent of the brood removed had no effect on nest failure rates. Nest failure prior to offspring swim‐up was more common, but unrelated to brood size after removal, in the lake with higher post‐spawning mortality and lower growth and fecundity. Brood size after removal was negatively related to nest failure in the lake with high survival, growth and fecundity. Nests guarded by young males failed more frequently than those of old males, and young broods failed more frequently than old broods. Dynamic programming and logistic regression models developed to predict nest fate worked better for the lake with selective pressures that theoretically favoured abandonment (e.g. high post‐spawning mortality). Both models identified male age and brood age as important factors in predicting nest fates. Because nest success is related to the age of the parent, this could have consequences for overall nest success for populations with different demographics.     

Thermal tolerance of paralarvae of Patagonian red octopus Enteroctopus megalocyathus

Patagonian red octopus, Enteroctopus megalocyathus, is a merobenthic octopus whose paralarvae have been successfully cultured up to juvenile octopuses. At present, high mortality during the paralarval period prevents the scaling from experimental rearing to commercial aquaculture. The aim of the study was to determine upper (CTMax) and lower (CTMin) thermal tolerance, acclimation response ratio (ARR) and thermal tolerance polygon of paralarvae from different culture conditions and subjected to seven acclimation temperatures (6, 8, 10, 12, 14, 16, 18°C) during the first 5 days of paralarval life. Culture conditions were two types of egg incubation (maternal care and artificial incubators) and two feeding regimes (fed or starved). Fed paralarvae showed thermal preferendum, while unfed paralarvae preferred much higher temperatures than those of acclimation. CTMin and CTMax increased along with the acclimation temperature. Lower values of ARR were obtained in paralarvae from artificial incubation, with this type of paralarva showing the least adaptability to thermal changes. Starved paralarvae showed the lowest values for thermal tolerance range (TTR) and smaller areas of thermal polygon than fed paralarvae. Rearing temperatures above 16°C may be considered suboptimal to paralarvae and affected by the conditions during the embryonic incubation. Rearing temperatures below 8°C may be considered suboptimal for all hatched paralarvae. Therefore, the other temperatures within this range could be used in the context of improving the culture management of paralarvae.     

社区照顾——城市老年人的赡养方式新选择

在经济及社会保障尚未做好准备的情况下，我国已进入了老龄化社会。随着家庭核心化以及老年人寿命的延长、年轻人工作压力的增大，这种4一2一1的家庭结构模式使得传统的家庭养老模式受到了极大的挑战。特别是我国城市的老年人的照料和需求等养老问题表现得越来越突出。本文旨在对家庭养老、机构养老和社区照顾的三种模式做一个简单的比较分析:不同的赡养模式的优势和不足，以便试图提出在目前的境况下的一个以社区照顾为本的城市老人赡养模式。
