Feeling freedom: Japanese and American wartime films on the liberation of the Philippines, 1943–1945
Takashi Fujitani 《Inter-Asia Cultural Studies》2018,19(4):510-525
ABSTRACTThis article juxtaposes the Japanese wartime film Dawn of Freedom and Hollywood films on the Philippines during WWII as a method to analyze the representational strategies by which the U.S. and Japanese empires tried, respectively and in opposition to the other, to nurture the feeling that the peoples of the Philippines and beyond would enjoy freedom under their stewardships. Under pressure from the twin crises of colonialism and capitalism, the two empires sought to establish hegemony in the Asia-Pacific by fashioning a new model of empire that disavowed imperialist intentions and territorial aggrandizement while promising freedoms that included but went beyond national self-determination. The article focuses on four overlapping freedoms that run through the Japanese and Hollywood films: namely, political self-determination/consumerist freedom, freedom of self-sacrifice or the freedom to die, freedom in romance, and freedom from racism. Despite their differences, the author argues that the two sides in the imperial film wars shared much more than what is commonly realized and that the new strategy that advanced and yet disavowed imperialist ambitions while promoting the feeling of freedom, has great relevance for understanding the militarized world today. 相似文献

This paper proposes a method to improve retrieval performance of the vector space model (VSM) in part by utilizing user-supplied information of those documents that are relevant to the query in question. In addition to the user's relevance feedback information, information such as original document similarities is incorporated into the retrieval model, which is built by using a sequence of linear transformations. High-dimensional and sparse vectors are then reduced by singular value decomposition (SVD) and transformed into a low-dimensional vector space, namely the space representing the latent semantic meanings of words. The method has been tested with two test collections, the Medline collection and the Cranfield collection. In order to train the model, multiple partitions are created for each collection. Improvement of average precision of the averages over all partitions, compared with the latent semantic indexing (LSI) model, are 20.57% (Medline) and 22.23% (Cranfield) for the two training data sets, and 0.47% (Medline) and 4.78% (Cranfield) for the test data, respectively. The proposed method provides an approach that makes it possible to preserve user-supplied relevance information for the long term in the system in order to use it later. 相似文献

全球化进程的深入发展要求对为西方中心论所遮蔽的亚洲历史进行重构,王正毅、滨下武志的探索表明,亚洲本土学的重构亚洲史的工作正处于逐步深入的阶段;在理论取向上,他们试图跳出本土论与照搬西方理论的范畴;在做法上,目前多是侧重于对中观层面的关注或对具体问题的深度挖掘。 相似文献

In the business-systems-design learning environment, there may be more than one solution to any given problem. For instance,
the data model will be different depending on each learner’s perspective. Accordingly, group learning systems are very effective
in this domain. We have developed a collaborative and multimedia environment for learners on teams (CAMELOT) using the ‘nominal
group technique’ for group problem solving. In this paper, the basic framework of the collaborative learning system and the
effectiveness of collaborative learning in designing the data model are described. By using CAMELOT, each learner learns how
to analyse through case studies and how to collaborate with his or her group in problem solving. Learners come to a deeper
understanding from using CAMELOT than from studying independently because they can reach better solutions through discussion,
tips from other learners and examination of one another’s individual works. 相似文献

Abstract In this study, we examined hamstring muscle activation at different running speeds to help better understand the functional characteristics of each hamstring muscle. Eight healthy male track and field athletes (20.1 ± 1.1 years) performed treadmill running at 50%, 75%, 85%, and 95% of their maximum velocity. Lower extremity kinematics of the hip and knee joint were calculated. The surface electromyographic activities of the biceps femoris and semitendinosus muscles were also recorded. Increasing the running speed from 85% to 95% significantly increased the activation of the hamstring muscles during the late swing phase, while lower extremity kinematics did not change significantly. During the middle swing phase, the activity of the semitendinosus muscle was significantly greater than that of the biceps femoris muscle at 75%, 85%, and 95% of running speed. Statistically significant differences in peak activation time were observed between the biceps femoris and semitendinosus during 95%max running (P < 0.05 for stance phase, P < 0.01 for late swing phase). Significant differences in the activation patterns between the biceps femoris and semitendinosus muscles were observed as running speed was increased, indicating that complex neuromuscular coordination patterns occurred during the running cycle at near maximum sprinting speeds. 相似文献

Most cytokine receptors including interleukin (IL)-9 have soluble counterparts in body fluids. We planned to investigate the pathophysiological significance of the serum soluble IL-9 receptor (sIL-9R) level. We determined the serum sIL-9Rα chain (sIL-9Rα) levels in 96 healthy Japanese individuals to establish a control value by means of specific human sIL-9Rα ELISA, followed by a preliminary application in a patient with diarrhea positive hemolytic uremic syndrome. Age was negatively correlated with the sIL-9Rα level (Spearman r = −0.241, n = 96, p = 0.0180). The serum sIL-9Rα level showed a progressive decline to the normal adult level by the age of 30. The serum sIL-9Rα level of the patient with HUS was markedly higher than those of the age-matched control from the onset of the disease. Because of the remarkable age-dependent variability of sIL-9Rα in healthy subjects, disease-related changes, as well as therapy-dependent alterations, should be considered with caution. Thus, it is recommended that when the serum sIL-9Rα levels of patients are evaluated, the values should be compared with those of age-matched controls. The established control value will be used to discriminate between normal and the pathological conditions in our future studies. 相似文献

Cross‐cultural Similarities in Attitudes toward Computers and the Implications for Teacher Education
Gerald Knezek Keeko Miyashita Takashi Sakamoto 《Technology, Pedagogy and Education》2013,22(2):193-204
ABSTRACT Results of a three year longitudinal study of elementary school children's attitudes toward computers in Japan, Mexico, and the United States of America are presented, along with implications of the findings for teacher education. Two types of attitudes toward computers (importance and enjoyment) were found to be positively influenced by the introduction of computer activities in primary school. No novelty effect was found regarding enjoyment of computers, and perceived computer importance declined less from Grades 1–3 than several other dispositions measured. No consistent gender differences were found for attitudes toward computers among the three nations. These findings imply that students begin school eager to learn about computers and lacking the gender biases often found in older age groups, and that teachers should be educated to help preserve interest in and access to information technology for all students. Reflections for teacher education conclude the article. 相似文献
