馆藏壁画的历史信息与现状调查

馆藏壁画是博物馆藏品中一类特殊的文物。在馆藏大召寺壁画、陕西唐墓壁画等现状调查研究的基础上,本文分析馆藏壁画区别于原址壁画的特殊性,并提出针对馆藏壁画特点进行历史信息与现状调查的内容框架。强调壁画揭取历史、修复史、搬运史和保存环境等历史信息的调查对于认知壁画的重要性：壁画的现状调查包括本体调查和病害调查两部分,能够帮助保护工作者以科学的视角综合评价壁画保存现状。本文分别论述调查各个方面的意义、具体内容和方法。调查结果无疑对于制定保护修复方案具有重要意义,为合理实施保护修复提供科学依据,并为后续研究和档案记录提供基础信息。     

湖北十堰潘口水电站三处古遗址的发掘

潘口水电站与陕南和川东接壤,是古庸国所在地.遗址地处河流边缘地带,长年受河水的冲刷,破坏殆尽,出土遗物甚少,文化内涵主要包含新石器晚期和东周时期遗存.东周时期文化面貌较为复杂,既有楚文化特征又具巴蜀文化风格,同时还包含陕南文化因素,这种多元文化因素,是与周边文化相互影响、碰撞形成的一种以地方文化为特色的多元文化.因此,我们认为潘口水电站淹没区的小府坪、红花湾、王家套等遗址是东周时期楚灭庸后的一处村落遗址.

信息全球化下的博物馆传播研究

博物馆既具备传播媒介的基本条件,与其他传播媒介相比,又更具可感知性和文化承载性等独特的优势。在信息时代的新环境下,博物馆作为收藏、展示、研究文化遗产的特殊媒介,需要树立博物馆的媒介威望,采用新的展示、讲解手段,以宣传片、网站等方式扩大博物馆的品牌影响,以此来更好地满足社会大众的需求。     

Blogging geographies

This paper responds to the call for research on the use of new information technologies in higher education contexts. This was done through a case study on the use of blogs in an advanced seminar class. The paper argues that the use of blogs provided a way of gauging how students were coming to terms with the course material and how they were engaging with the course texts. Intertextuality was used as a method of understanding how students engaged with the course. The analysis was based on blog postings, student comments, course evaluations and the instructor's reflective journal.     

A Preliminary Investigation into the Challenges of Learning GIS in Interdisciplinary Research

A geographic information system (GIS) can be a valuable research tool, helping scientists understand location and bridge the gaps between subjects in interdisciplinary research (IDR), which has been promoted for its real-world solutions. However, a GIS can be difficult to use and may require understanding of a number of concepts as well as tools and technology. This complexity is compounded by additional challenges commonly encountered in IDR. This paper examines some of the challenges facing learners of GIS in IDR projects, with a particular focus on the appropriateness of current teaching methods in this context.     

Doing Independent Overseas Fieldwork 1: Practicalities and pitfalls

This article explores issues of scalability and sustainability in distance learning. The authors kept detailed records of time they spent teaching a course in geographic information science via the World Wide Web over a six-month period, during which class sizes averaged 49 students. The authors also surveyed students' satisfaction with the distance learning course through ratings and open-ended questions. Findings are compared with similar data collected a year earlier, when class sizes associated with the same distance learning course averaged 18 students. In response to the increase in average class size by a factor of 2.7, the authors' course-related workloads increased by a factor of about 2.5 (from 47.5 hours to 116.7 hours total). Analyses of student feedback suggest that student satisfaction with the course was high overall and suffered no significant decline as a result of increased instructional efficiency.     

The Right Tool for the Job: The Canalization of Presidential Policy Attention by Policy Instrument

This article investigates how presidential policy attention is allocated across policy tools and whether there is a channeling of tool use by policy area. I also examine whether there is evidence of disproportionate information processing within presidential policy attention allocation and whether it is common across presidential policy tools. Presidential messages, hearings on administrations' legislative proposals, amicus briefs, and executive orders are employed to capture presidential policy tools. The allocation of attention via these four instruments is examined from 1957–2007 in the policy areas of defense and foreign affairs, macroeconomics, banking and commerce, civil rights, law and crime, and labor and immigration. I find that there is a canalization of presidential policy attention by instrument, and that the opportunity structure of policy tools shapes attention allocation. Additionally, I find evidence for punctuated equilibrium theory in the allocation of presidential policy attention via these four tools. When presidents do shift their attention to an issue area, they often attack the issue with some coordination of their policy instruments.     

3D reality-based artefact models for the management of archaeological sites using 3D Gis: a framework starting from the case study of the Pompeii Archaeological area

This work describes the procedures, the different techniques and the pipeline used for creating a digital framework that should assist the Superintendence of Pompeii in the digital reconstruction, classification, management and visualisation of archaeological finds inside an advanced 3D web-based repository of reality-based data. Specific topics have been focused on the quality assessment procedures adopted to ensure consistency and reliability of data throughout the whole 3D models acquisition and pipeline creation, as well as on the particular semantic reality-based structure adopted to develop an information system into a knowledge one. The main purposes of our framework have been the usage of 3D digital models as a restitution of the real object and as a metaphor for navigating through the data; 3D models were used as archaeological cognitive systems and developed as a collection of structured objects, identified through a precise terminology that allows to easily extend the concept of 2D GIS to 3D GIS. In addition, the system was developed as a scalable application that allows the use of the same database by different users, simply filtering the data according to the specific requirements, and can operate both as standalone and web-based application.
