Does digital video enhance student learning in field-based experiments and develop graduate attributes beyond the classroom?

The connection between fieldwork and development of graduate attributes is explored in this paper. Digital technologies present opportunities to potentially enhance the learning experience of students undertaking fieldwork, and develop core digital attributes and competencies required by Higher Education Institutions (HEIs) and employers. This paper reports the success of adopting digital video capture in technology-rich field experiments that form part of final year undergraduate courses in Physical Geography at an HEI in New Zealand. Student perceptions were obtained via a range of approaches. Results suggest that deployment of digital video reinforces student learning and connects with core graduate attributes.     

Field gamma spectrometry,Monte Carlo simulations and potential of non-invasive measurements

The determination of gamma dose rates is of prior importance in the field of luminescence dating methods. In situ measurements are usually performed by the insertion of dosimeters or a portable gamma spectrometer cell in sediments. In this paper, Monte-Carlo simulations using the Geant4 toolkit allow the development of a new technique of insitu gamma dose rate evaluations: a spectrometer cell is placed on the surface of sediments under excavation to acquire successive spectra as sediments are removed by excavations. The principle of this non-invasive technique is outlined and its potential is discussed, especially in the case of environments in which radioelements are heterogeneously distributed. For such cases, a simple method to reconstruct gamma dose rate values with surface measurements using an attenuator is discussed, and an estimation of errors is given for two simple cases. This technique appears to be applicable, but still needs experimental validation.     

辽代医药学发展浅析

一、前言契丹族是中国古代北方强族,公元4世纪左右开始在西拉木伦河和老哈河一带游牧。公元916年,契丹迭剌部首领耶律阿保机统一契丹各部,建立大契丹国,后改国号为大辽,称雄中国北方数百年,与北宋、西夏形成三足鼎立之势。有辽一代,契丹族政治、经济、文化有长足的发展,辽代医药学也有一定的发展。辽代医药学发展上承隋唐、五代,旁及宋及周边民族的先进经验,加之自己八百余年的医学实践,在医学理论、疗法、疗术、方、散、丹、丸的研制以及食疗,保健等方面都有一定的建树,甚至有自己的发明和创新。历史步入21世纪后,在全世界范围内非常重视对…     

顾颉刚藏书记(上)

顾颉刚先生(原名诵坤,字铭坚)于1980年12月逝世,根据其"藏书不要分散,以便后人利用"的遗愿,家属将其藏书捐献给中国社会科学院,1981年先由历史研究所代管,1988年由文献信息中心(当时称文献情报中心)正式接收,成立"顾颉刚文库".

(二) 余嘉锡先生藏书极多,"但只有明清刻本,而没有宋元珍本.因为他是为读书而买书,……所藏的书凡是四部有用的书和丛书大都具备,与藏书家收藏古本不同.     

天一阁藏万斯同《明史稿》考论

天一阁藏万斯同《明史稿》,是万斯同四百十六卷本《明史》之底本,其中大量的朱笔校语与校迹亦在《明史》编纂学上有重要研究价值。本文仅就此略呈管见,以期对万斯同及《明史》研究有所裨益。     

前马克思主义阶级斗争理论的传播与发展

阶级斗争理论在古希腊提出后,通过神学家的译著在中世纪得到了传播。而在雏科的《新科学》中,这一理论继亚里士多德之后第一次用来分析历史上的阶级斗争。阶级斗争理论的发展则主要是通过圣西门的政治理论和法国复辟时期的历史理论实现的。圣西门不仅突破了阶级划分的传统标准,而且提出了新的阶级概念。更为重要的是,他重视和强调经济因素的作用,提出了所有制的概念。复辟时期的历史学家则使传统的说明由具体上升为一般,将阶级划分标准和阶级斗争爆发的原因概括为“利益关系”,并在阶级斗争的功用问题上提出了动力理论。
