The Role of Ethics,Culture, and Artistry in Scientific Illustration

This article is a case-based theoretical exercise designed to investigate the role that ethics, culture, and artistry play in scientific illustration. In this article, the author theorizes a visual model of cultural interplay and scientific illustration in the creation of scientific knowledge and argues that scientific illustrations work as epistemological devices because they are culturally mediated constructions imbued with personal, organizational, and disciplinary trust, and shaped by the embedded cultural worldviews.

Facilitating Chemistry Teachers to Implement Inquiry-based Laboratory Work

Science teachers generally find inquiry-based laboratory work very difficult to manage. This research project aimed at facilitating chemistry teachers to implement inquiry-based laboratory work in Hong Kong secondary schools. The major concerns of seven chemistry teachers were identified. They were most concerned about the lack of class time, shortage of effective instructional materials, and the need to teach large classes. To allay teacher concerns, teaching strategies were developed to aid teachers. The strategies include the use of guided inquiry rather than open inquiry, development of ten examples of authentic inquiry, and inclusion of student oral presentations as a key component of the inquiry process. Trials done in schools indicated that these strategies are useful.     

Free-weight resistance exercise on pulse wave reflection and arterial stiffness between sexes in young,resistance-trained adults

We sought to determine the sex-specific effects of an acute bout of free-weight resistance exercise (RE) on pulse wave reflection (aortic blood pressures, augmentation index (AIx), AIx at 75?bpm (AIx@75), augmentation pressure (AP), time of the reflected wave (Tr), subendocardial viability ratio (SEVR)), and aortic arterial stiffness in resistance-trained individuals. Resistance-trained men (n?=?14) and women (n?=?12) volunteered to participate in the study. Measurements were taken in the supine position at rest, and 10 minutes after 3 sets of 10 repetitions at 75% 1-repetition maximum on the squat, bench press, and deadlift. A 2?×?2?×?2 ANOVA was used to analyse the effects of sex (men, women) across condition (RE, control) and time (rest, recovery). There were no differences between sexes across conditions and time. There was no effect of the RE on brachial or aortic blood pressures. There were significant condition?×?time interactions for AIx (rest: 12.1?±?7.9%; recovery: 19.9?±?10.5%, p?=?.003), AIx@75 (rest: 5.3?±?7.9%; recovery: 24.5?±?14.3%, p?=?.0001), AP (rest: 4.9?±?2.8?mmHg; recovery: 8.3?±?6.0?mmHg, p?=?.004), and aortic arterial stiffness (rest: 5.3?±?0.6?ms; recovery: 5.9?±?0.7?ms, p?=?.02) with significant increases during recovery from the acute RE. There was also a significant condition?×?time for time of the reflected wave (rest: 150?±?7?ms; recovery: 147?±?9?ms, p?=?.02) and SEVR (rest: 147?±?17%; recovery: 83?±?24%, p?=?.0001) such that they were reduced during recovery from the acute RE compared to the control. These data suggest that an acute bout of RE increases AIx, AIx@75, and aortic arterial stiffness similarly between men and women without significantly altering aortic blood pressures.     

The effect of biofeedback training on affective regulation and simulated car-racing performance: a multiple case study analysis

The foundation of this study was based on an idiosyncratic concept, which uses probabilistic determinations (Kamata, Tenenbaum, & Hanin, 2002) to verify the utility and effectiveness of a biofeedback intervention by manipulating affective performance states in a race-car simulator. Nine males completed five separate time-trials of a simulated racing task and were then randomly assigned to one of three arousal regulation treatment conditions: (1) optimal, (2) poor, and (3) attention control. Following the biofeedback intervention, participants underwent another series of race trials to determine the effectiveness of the arousal regulation intervention. The results indicated that there were relative similarities in the strength and direction of the perceived and physiological states between the participants; however, the subtle details of the participants' unique performance zones and the probability of achieving each zone were revealed to be unique among the participants. The results also indicated that: (a) the biofeedback manipulation resulted in the expected changes for each participant, and (b) there were some large individual differences among the participants, necessitating the idiosyncratic approach. Limitations and future directions are also addressed.     

怎样做一个尽职尽责的校长

作为一名大学校长,他必须足够熟悉校长最重要的几项任务：首先,大学校长必须捍卫质疑和探索的自由,这是在大学各个机构里工作的教职工从事教学、学术研究,提高职业道德和满足自我尊重的基础。其次,大学校长必须为大学的发展积累和发掘资源,无论是在艰苦还是繁荣时期。他必须致力于保持高水平的教学质量以确保当代人才的培养,不能对这代学生以及以后学生受教育的质量构成威胁。当然,大学校长必须使大学摆脱可能会产生认为自己已经很优秀的这种自满倾向。他必须唤醒各个学院的院长和教职工以及所有与大学紧紧相联的人员为实现其大学所能够达到的奋斗目标而努力。
