New Philadelphia: using augmented reality to interpret slavery and reconstruction era historical sites

Does a historical site lose its significance or become less worthy of interpretation if there are no surviving buildings? Can technology help present the stories of disadvantaged and disenfranchised groups whose heritage lacks well-preserved architecture or material culture? The emerging technology of augmented reality (AR) offers new ways of designing and shaping the public’s experience when visiting landmarks by enabling an unprecedented means to combine 3D historical visualization with historical landmarks. This especially applies to underrepresented groups whose heritages have not been well served by traditional modes of preservation and interpretation due to a variety of factors. These range from disadvantages relating to material culture to a greater emphasis on intangible heritage which have placed them outside the bounds of what archaeologist Laurajane Smith calls authorised heritage discourse. A project at the New Philadelphia National Historic Landmark, located in Pike County Illinois, seeks to address these issues through AR. The technology, while offering opportunities for historical interpretation, poses challenges in terms of designing AR systems that coordinate content presentation with specific locations as well as developing virtual historical content with varying levels of source materials.     

WHAT IS HISTORY? WHAT IS LITERATURE?

Ivan Jablonka seeks something other than a mere combination of history, social science, and literature. He would like history, itself understood as a social science, to be a literature of the real world. He is also interested in literature informed not only by the results but, more important, by the forms of reasoning and inquiry of history and related social sciences (notably anthropology and sociology). Jablonka's own positioning within the Annales seems obvious, notably in his stress on cognition, problem‐oriented research, and the status of history as a social science. But the attention and research devoted in the work of scholars in and around the Annales to the relations among history, literature, and fiction have not been pronounced, and in this context Jablonka inflects the understanding of history in relatively underdeveloped directions. Despite possible disagreements one may have over specific issues, Jablonka's thought‐provoking book raises very important questions, opens many significant avenues of inquiry, and seeks a desirable interaction between historical and literary approaches.

(de)Constructing Place-Myth: Pitcairn Island and the “Bounty” Story

Abstract

This paper is concerned with the relationship between literature and the construction of place-myth relating to the story Mutiny on the Bounty. In 1790, nine British mutineers together with their Tahitian companions settled on Pitcairn Island where they remained hidden for nearly 20 years. The story of the mutiny is not myth but has served to mythologize Pitcairn through the various tropes of literature written about the Bounty saga. As literary place Pitcairn represented the image of a ‘utopian paradise’. This discussion, through qualitative literary analysis and the process of textualization, evokes the idea of mapping, naming, and imagining islands. It identifies how the utopia/paradise place-myth of Pitcairn has persisted through time and become ultimately inseparable from its textual topography. But conversely, discussion exposes the paradoxical problem between myth and reality of islands and their representations. It highlights complex internal and external boundaries of identification that arise in the host visitor experience. Literary place-myth is rendered as powerful, persistent, mutable, and historically-rooted.     

数字时代的历史事实建构——以电子族谱编撰为例

近年在网络世界出现的帮助用查考及编撰族谱的网页,是探讨数码时代在万维网上衍生的历史叙述的建构过程,以及其有可能产生的社会和心理后果的一个例证。电子族谱在内容上虽然可以沿用既有的手钞和印刷族谱的素材,然而,电子族谱所衍生的编撰传统绝对不能视作手钞和印刷族谱的延续。相反,电子时代的族谱编撰和字时代的族谱编撰,分别见证着两种不同的社会事实建构的过程。进入数码时代,族谱的编撰很有可能从一个传统的、集体的、乡村社会的配套仪式,变成是个人的、存在于城市和网络空间的孤立的仪式。     

求新动机、满意度对重游间隔意愿的影响——以凤凰古城旅游者为例

由于重游所带来的经济利益日益凸显,使得重游问题受到学界的广泛关注。本研究以湖南凤凰古城为案例地,采用问卷调查获得基础数据,建立结构方程模型从求新动机、满意度两个方面考究旅游者重游间隔意愿的形成机制。研究发现,在凤凰古城这样的快速发展旅游地,求新动机会直接影响旅游者的短期重游意愿,但对中期、长期重游意愿则没有显著的直接影响,同时求新动机会对满意度产生积极的影响。     

Watermills: The Origin of the Use of Renewable Hydraulic Energy in Spain

The use of renewable hydraulic energy sources by mankind most likely has its origins in the development of the watermills. To understand the functioning of these mills, this article first reviews, through the analysis of different bibliographical sources, the technical evolution of the machinery used since the appearance of the first watermills to grind cereal grain in the 1st century bc.

Secondly, a particular area of the south-west of Spain, Alcalá de Guadaíra, has been selected for study, whose strategic location as well as its hydrological characteristics gave rise, firstly, to an intensive milling industry, and, later, a famed baking industry, from the late Middle Ages until recent decades. The huge development of these two industrial activities has made Alcalá de Guadaíra an exceptional example in Spain, with 40 watermills in the early 18th century.

Extensive work on site allowed the analysis of the state and types of watermills that still exist in this area, identifying their similarities and differences. Unfortunately, after they fell into disuse, only 28 of these mills remain today; 12 of them are in a relative good state of preservation, seven in an alarming state of ruin and, of the other nine, only some unrecognisable vestiges remain. Some of these mill buildings have been restored recently, although their machinery is missing. Only from old photographs or by visiting mills restored in other areas is it possible to determine how these watermills worked.

Due to the lack of financial resources to carry out physical restoration of the industrial heritage missing in these flour mills, a virtual model of one of them has been developed. This work provides, at least virtually, a reconstruction of the traditional mills which helps promote technological studies and shows how they worked, as part of virtual exhibitions. In addition, a computer application of augmented reality has been developed that any visitor can install on a mobile device to display the virtual reality of the machinery, generated by 3D models, so they can visualise the physical reality that they would have found in the mill.     

The impact of mobile augmented reality in geography education: achievements,cognitive loads and views of university students

Augmented reality (AR) technology is commonly used in education. AR offers a combination of the virtual and real world; thus, it can help students in learning abstract and complex subjects. The purpose of the current study was to determine the impact of mobile AR technology on achievement, cognitive load levels and views of 95 first-year university students (40 in the experimental group and 55 in the control group) enrolled in a geography course in the social sciences education department of the education faculty of a university in Turkey. A sequential explanatory design, a mixed method type of research, was used. The data were collected using an achievement test, a cognitive load scale, and a semi-structured interview form. The results of the study showed that AR increases students’ achievement and decreases their cognitive load levels, and the students’ views about AR technology were positive. Consequently, it can be stated that mobile AR technology is a useful tool for teaching geography, especially geomorphology topics.     

Landscape interpretation with augmented reality and maps to improve spatial orientation skill

Landscape interpretation is needed for navigating and determining an orientation: with traditional cartography, interpreting 3D topographic information from 2D landform representations to get self-location requires spatial orientation skill. Augmented reality technology allows a new way to interact with 3D landscape representation and thereby facilitate the orientation of oneself in respect to the environment to determine goal location. This paper analyses if AR spatial landform improves the learner’s spatial orientation skill measured with the perspective taking/spatial orientation test by paired sampled t-tests. A workshop was conducted with 123 university students (63 treatment group, 60 control group) in which students had to identify locations and routes based on the interpretation of the relief, represented by AR. Results of the workshop showed an improvement in spatial orientation skill of 20.14 degrees average gain in the treatment group. Students who were not subject to the workshop (control group) did not improve their spatial orientation skill. The possibility of using free AR three-dimensional applications and exploit the potential of tablets and smart phones, which are widespread today, makes it possible to design and implement strategies for the development of spatial skills in formal teaching in the scope of Geography in higher education.     

汪精卫对日求和的政治环境及其思想脉络

汪精卫对于抗战从悲观失望发展为公开主和,有其思想演变的脉络,也有促成其思想演变的国际、国内环境。汪精卫反对国民党采取"远交近攻"的外交战略,不信任英美对中国抗战的援助,并在日本与苏联之间,选择了亲日、反苏。汪不相信国民党能在既反日、又不依附苏联、也得不到英美支持的情况下,建立起一个独立自主的国家。并坚信他的求和主张能在政军两界激起普遍"回响"。这是他不惜离渝而对日求和的根本原因。
