Finding and explaining differences: A reply to Gudykunst and Hammer     

Richard L. Wiseman  Hiroko Abe 《Int J Intercult Relat》1984,8(1):11-16

A rejoinder to Gudykunst and Hammer's critique of a recent paper is presented. We argue that their position is based on two mutually exclusive propositions and cannot therefore be credible. We continue to maintain that the evidence on intercultural effectiveness shows both culture-general and culture-specific components.  相似文献   

Sequential muscle activity and its functional role in the upper extremity and trunk during overarm throwing   总被引：1，自引：1，他引：0

The proximal-to-distal segmental sequence has been identified in many sports activities, including baseball pitching and ball kicking. However, proximal-to-distal sequential muscle activity has not been identified. The aims of this study were to establish whether sequential muscle activity does occur and, if it does, to determine its functional role. We recorded surface electromyograms (EMGs) for 17 muscles from the upper extremity and abdomen during overarm throwing and detected the onset and peak times as indices of muscle activity. The following electromyographic properties were commonly identified in the participants. First, sequential muscle activity was observed from the scapular protractors to the shoulder horizontal flexors and from the shoulder horizontal flexors to the elbow extensor, but not from the elbow extensor to the wrist flexor or forearm pronator. Secondly, the external oblique contralateral to the throwing arm became activated before the ipsilateral external oblique. This sequence is considered to be very effective for the generation of high force and energy in the trunk. Thirdly, the ipsilateral external oblique began its activity almost at foot strike. Finally, the main activity of the rectus abdominis appeared just before the point of release.  相似文献   

Consensus of linear multi-agent systems based on full-order observer     

Zixi Li  Hiroshi Ishiguro 《Journal of The Franklin Institute》2014

This paper considers distributed consensus problem of multi-agent systems consisting of general linear dynamics with a time-invariant communication topology. A distributed full-order observer type consensus protocol based on relative output measurements of neighbor agents is proposed. It is found that the consensus problem of linear multi-agent systems with a directed communication topology having a spanning tree can be solved if and only if all subsystems are asymptotically stable. Some necessary and sufficient conditions are obtained for ensuring consensus in multi-agent systems. The design technique is based on algebraic graph theory, Riccati inequality and linear control theory. Finally, simulation example is given to illustrate the effectiveness of the theoretical results.  相似文献   

Automatic extraction of bilingual word pairs using inductive chain learning in various languages     

Hiroshi Echizen-ya  Kenji Araki  Yoshio Momouchi 《Information processing & management》2006

In this paper, we propose a new learning method for extracting bilingual word pairs from parallel corpora in various languages. In cross-language information retrieval, the system must deal with various languages. Therefore, automatic extraction of bilingual word pairs from parallel corpora with various languages is important. However, previous works based on statistical methods are insufficient because of the sparse data problem. Our learning method automatically acquires rules, which are effective to solve the sparse data problem, only from parallel corpora without any prior preparation of a bilingual resource (e.g., a bilingual dictionary, a machine translation system). We call this learning method Inductive Chain Learning (ICL). Moreover, the system using ICL can extract bilingual word pairs even from bilingual sentence pairs for which the grammatical structures of the source language differ from the grammatical structures of the target language because the acquired rules have the information to cope with the different word orders of source language and target language in local parts of bilingual sentence pairs. Evaluation experiments demonstrated that the recalls of systems based on several statistical approaches were improved through the use of ICL.  相似文献   

An integrated teaching method of gross anatomy and computed tomography radiology          下载免费PDF全文

Tohru Murakami  Yuki Tajika  Hitoshi Ueno  Sachiko Awata  Satoshi Hirasawa  Maki Sugimoto  Yoshihiko Kominato  Yoshito Tsushima  Keigo Endo  Hiroshi Yorifuji 《Anatomical sciences education》2014,7(6):438-449

It is essential for medical students to learn and comprehend human anatomy in three dimensions (3D). With this in mind, a new system was designed in order to integrate anatomical dissections with diagnostic computed tomography (CT) radiology. Cadavers were scanned by CT scanners, and students then consulted the postmortem CT images during cadaver dissection to gain a better understanding of 3D human anatomy and diagnostic radiology. Students used handheld digital imaging and communications in medicine viewers at the bench‐side (OsiriX on iPod touch or iPad), which enabled “pixel‐to‐tissue” direct comparisons of CT images and cadavers. Students had lectures and workshops on diagnostic radiology, and they completed study assignments where they discussed findings in the anatomy laboratory compared with CT radiology findings. This teaching method for gross and radiological anatomy was used beginning in 2009, and it yielded strongly positive student perspectives and significant improvements in radiology skills in later clinical courses.

Combined effects of exposure to hypoxia and cool on walking economy and muscle oxygenation profiles at tibialis anterior     

Masahiro Horiuchi  Yoko Handa-Kirihara  Daijiro Abe  Yoshiyuki Fukuoka 《Journal of sports sciences》2019,37(14):1638-1647

We investigated combined effects of ambient temperature (23°C or 13°C) and fraction of inspired oxygen (21%O₂ or 13%O₂) on energy cost of walking (C_w: J·kg^?1·km^?1) and economical speed (ES). Eighteen healthy young adults (11 males, seven females) walked at seven speeds from 0.67 to 1.67 m s^?1 (four min per stage). Environmental conditions were set; thermoneutral (N: 23°C) with normoxia (N: 21%O₂) = NN; 23°C (N) with hypoxia (H: 13%O₂) = NH; cool (C: 13°C) with 21%O₂ (N) = CN, and 13°C (C) with 13%O₂ (H) = CH. Muscle deoxygenation (HHb) and tissue O₂ saturation (StO₂) were measured at tibialis anterior. We found a significantly slower ES in NH (1.289 ± 0.091 m s^?1) and CH (1.275 ± 0.099 m s^?1) than in NN (1.334 ± 0.112 m s^?1) and CN (1.332 ± 0.104 m s^?1). Changes in HHb and StO₂ were related to the ES. These results suggested that the combined effects (exposure to hypoxia and cool) is nearly equal to exposure to hypoxia and cool individually. Specifically, acute moderate hypoxia slowed the ES by approx. 4%, but acute cool environment did not affect the ES. Further, HHb and StO₂ may partly account for an individual ES.  相似文献   

An Instrumental Case Study Analysis of Anticipatory Leadership Practices in Community Colleges     

Abe Johnson 《Community College Journal of Research & Practice》2018,42(6):389-404

This qualitative instrumental case study explored the experiences and perceptions of seven community college leaders of their use of anticipatory leadership. Two research questions guided this study: (a) How do community colleges use anticipatory leadership to respond to internal and external changes? (b) How do community college leaders use anticipatory leadership principles for problem solving? The themes that emerged to address question one were engagement with others is required to respond to change effectively, data analysis and currency of knowledge are required to identify gaps and to respond to them, leaders must be willing to take calculated risks, and leaders must communicate effectively in order for change to occur. The themes that emerged to address question two were analysis of data is instrumental to identifying and closing the gaps in institutions, leading to better informed decisions; and anticipatory leadership reduces the need to use reactionary leadership practices. The findings of the study are that the participants identified and supported that anticipatory leadership practices are effective for responding to change. The anticipatory leadership practices highlighted as needed by the participants included the need for leaders who are engaged, have the skills and ability to utilize data to make decisions, are current in their higher education knowledge, take calculated risks when needed, and can communicate effectively. These skills are needed for community college leaders to be able to be proactive versus reactionary in their decision-making, as well as effective with their gap analysis identification, trend predictions, decision-making, and problem solving.  相似文献
