Commemorative places,political spaces: Virginia Indians,the Jamestown Quadricentennial,and the quest for sovereignty

ABSTRACT

This essay examines the cross-cultural communication strategies deployed by a coalition of indigenous tribes in Virginia to leverage the Quadricentennial commemoration of the founding at Jamestown in support of their sovereignty campaign. The tensions between Jamestown’s mythos as the “birthplace of democracy” and the natives’ historical and contemporary lived experiences, combined with the national and international attention focused on the events, constructed the 400th anniversary “celebrations” as a compelling location for social action. The coalition employed intercultural communicative practices—particularly cross-cultural dialogue and negotiation—as means of mobilizing these tensions to renegotiate their relationship with the federal government, illustrating the intersection of intercultural communication, memory, and identity.     

Sanitizing the Struggle: Barack Obama,Selma, and Civil Rights Memory

In this article, I examine Barack Obama’s use of collective memory during his 2007 campaign speech in Selma, Alabama. Specifically, I argue that Obama appeals to collective memory to challenge the Black community’s relationship to the past. He reframed the memory of the Civil Rights Movement in a manner favorable to his political aspirations. While this frame was politically expedient, it weakened Black political agency. It robbed the Black community of crucial rhetorical resources used to challenge structural inequalities in society. This article offers insight into the complex relationship between metaphor and collective memory. Specifically, I interrogate the role of metaphor as a crucial site where public memory is formed, disrupted, and rearticulated. Furthermore, I consider the implications of his use of memory for the future of the Black freedom struggle.

社会融入视角下档案记忆建构问题探究

社会融入理论的应用在保障各类主体的社会权利、缓解社会矛盾、维护社会和谐、安定等方面具有重要的指导作用。近年来,随着我国有关档案记忆的研究逐步深入,社会融入理论在档案记忆建构活动中所具有的扩充档案记忆主体、保障公民档案权利、促进档案记忆服务于社会发展的价值被不断发掘。文章将从识别社会融入主体、建立信任与合作关系、针对性开发档案资源、扩大受众群体四方面对社会融入理论应用于档案记忆建构实践的基本情况进行探讨。     

国外档案记忆研究热点综述及启示

本文梳理了国外档案记忆的研究热点主题,包括档案与记忆关系、档案与权利关系、非传统档案与边缘记忆、档案与记忆建构四方面的主要观点及研究不足。国外研究对深化我国档案记忆研究有重要启示：增强学科知识建构意识,警惕泛档案学研究;加强队伍建设与培养,彰显国际档案记忆研究的中国声音;结合我国社会时代主题,反思理论走向与具体实践等。     

档案定义视阈下的原始记忆性本质及其逻辑结构

档案界对档案定义一般采用"属+种差"的逻辑形式,因而揭示档案本质、确定档案属种就成为档案定义的根本问题。档案记忆理论认为,档案是记忆的物质形态。档案以自身历史选择的必然性和逻辑结构的客观优势,成为人类自觉建构的外脑记忆的典型形式。作为用来建构原始记忆的历史文件,档案在物质形态上表现为档案实体,在逻辑关系上表现为记录和再现两个维度。以档案实体为基点,沿时空维度,向后回溯是档案记录关系维度,在档案记录关系的另一端是档案记忆的历史事实,这是档案记忆的客体;向前表述是档案再现关系维度,在档案再现关系的另一端是档案客体加以证明的回忆事实,这是档案记忆的证体。在这种逻辑结构中,档案实体即档案本身是档案"二维"逻辑关系和档案"三重要素"的物质载体。档案现象的实质就是以"二维"逻辑关系,凝聚"三重要素"的实践过程。     

Memory training program for older adults

ABSTRACT

Objective: Memory loss affects a large proportion of older adults. Research indicates a positive association between memory training and better memory performance as people age. However, studies on specific memory training using an experimental design are limited. This study explored whether memory training has improved memory performance in a group of older adults.

Method: A convenience sample of 48 participants was recruited from two communities. Disregarding dropouts, this left 23 experimental (mean age = 65.4 ± 6.0, range = 56–80) and 19 control participants (mean age = 64.5 ± 4.9, range: 57–72). The intervention consisted of 60-min classes held on a weekly basis continuing for 8 weeks. The class session was held after a 1-h exercise class and before a 1-h session of cognitive games. The pre–post objective memory performances, including associative, list, text, place, grocery learning, and transfer-effect of daily event memory (ecology validity), were examined to determine whether the intervention was effective.

Results: Intragroup: With Wilcoxon test, the findings showed that the intervention of both the list and place learning had significant differences for the experimental group, but not for the control group. Intergroup: The main effects were found for the associative and text learning. The mixed design ANOVA indicated that there is an interaction (time x group) on the dependent variable of the place learning test. Daily events memory: We found within group that the pre–post differences were significant for the experimental group but not for the control group.

Conclusion: The study showed that memory training can help older adults to ameliorate memory loss problems and these findings deserve more attention.
