随着科学技术的发展,知识经济时代的到来,知识量开始激增,学科之间相互交叉渗透,用户对知识的多元化需求趋势愈来愈明显。个性化信息服务正成为目前我国高职院校图书馆服务的发展方向。国务院颁布的关于大力发展职业教育的决定贯彻执行后,我国高等职业教育迎来了一个蓬勃发展的黄金时期。但是,现阶段高职院校图书馆个性化信息服务仍存在宣传力度不够、培训吸引力不强、技术力量薄弱等困境。高职院校只有摆脱这些困境,才能更好地发挥图书馆在高职院校技能型人才培养中的作用,更好的为用户服务。 相似文献

当前,计算机、信息化技术的高速发展使得网络已经成为民众生活中的必需品,图书馆作为传统时代背景下民众获取知识的重要渠道,其办馆理念、馆藏发展、馆员工作等多个领域都受到了网络环境的影响,特别是传统道德借阅流通服务,已经难以满足网络时代读者的全新要求,亟待相关专家对其进行解决。文章通过对相关文献进行查阅,对当前我国公共图书馆读者借阅行为特点进行了阐述,结合网络环境对于图书馆借阅流通服务造成的影响,最终提出了建立个性化服务模式、建立综合性服务模式、引进现代化借阅系统、提升馆内员工的素质四种网络环境下图书馆借阅流通服务创新策略。 相似文献

如今随着科学技术的快速发展,科学技术应用的领域更加的广泛,教育事业方面当然也不例外,尤其是高校的图书馆期刊阅览室方面,应用的也比较广泛,但在具体的管理方面仍然存在着些许的问题,尤其是在学生入门阅读方面、期刊读物摆放方面、期刊读物管理方面、期刊读物借阅管理方面都存在着部分的问题,为此,我国高校就必须更好地建立起生态化图书馆,加强对图书馆期刊阅览室的科学管理,通过学校熟悉计算机的专业人士更好地建立其高校图书馆期刊阅览室的阅读知识生态共享机制,以更好地加强对高校图书馆期刊阅览室的自动化管理和生态化管理,从而更好地为广大高校学生提供更好地课外学习平台,以更好地扩大他们的知识面。 相似文献

在现代法律秩序中,商会自治规范是制定法的基础和必要的补充,甚至在某些方面替代了制定法;商会自治规范主要包括商会组织规范、行为规范、惩罚规范以及争端解决规范等;其效力仅及于其内部成员;商会自治规范和制定法之间存在冲突,但也存在整合的基础。 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献
