As their name implies, computers were originally developed to make numerical calculations but they have already been applied to a relatively limited extent to handling data presented as written language, speech, graphs, and so on. With their Fifth Generation Computer project the Japanese have embarked on a startlingly ambitious ten-year scheme—supported jointly by government and industry—to develop non-numeric computers which embody artificial intelligence that can communicate directly with the human mind on a logical basis. 相似文献

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

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.

Interested in incorporating social media into your teaching but wary of the effort it might take? According to the research reviewed by Paige Abe and Nickolas A. Jordan, the challenge may be well worth it in terms of increased student engagement. 相似文献

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

To investigate the effects of a single high-load (80% of one repetition maximum [1RM]) set with additional drop sets descending to a low-load (30% 1RM) without recovery intervals on muscle strength, endurance, and size in untrained young men. Nine untrained young men performed dumbbell curls to concentric failure 2–3 days per week for 8 weeks. Each arm was randomly assigned to one of the following three conditions: 3 sets of high-load (HL, 80% 1RM) resistance exercise, 3 sets of low-load [LL, 30% 1RM] resistance exercise, and a single high-load (SDS) set with additional drop sets descending to a low-load. The mean training time per session, including recovery intervals, was lowest in the SDS condition. Elbow flexor muscle cross-sectional area (CSA) increased similarly in all three conditions. Maximum isometric and 1RM strength of the elbow flexors increased from pre to post only in the HL and SDS conditions. Muscular endurance measured by maximum repetitions at 30% 1RM increased only in the LL and SDS conditions. A SDS resistance training program can simultaneously increase muscle CSA, strength, and endurance in untrained young men, even with lower training time compared to typical resistance exercise protocols using only high- or low-loads. 相似文献

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 (Cw: 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
