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.     

The ‘Isle of Vice’? Youth,class and the post-war holiday on the Isle of Man

This article broadens our knowledge of post-war holidaymaking (c. 1950–80) by adopting the Isle of Man as a case study. A popular holiday resort from the late nineteenth century, the Isle of Man experienced considerable political turbulence during the 1950s and 1960s about how best to stay competitive as a seaside resort, where authorities employed uniquely stringent methods to contain rowdiness and protect the island’s ‘respectable’ atmosphere. The first two sections examine the leisure habits of the young and working class in a holiday context, integrating this analysis with perceptions of their behaviour gleaned from oral interviews with local residents. The concluding section explores how the presence of holidaymakers on the Isle of Man – uniquely among seaside resorts in the British Isles – informed (and in some cases emboldened) a sense of national identity. Oral history, complemented by the Hansard reports of the Isle of Man parliament and local press coverage, sheds light on the activities of the post-war working class at play, and how the presence of holidaymakers fortified Manx national consciousness.     

Building a Case for a Sociocultural and Inquiry-Oriented View of Science Education

Much constructivist writing has ignored the affective and social aspects of learning, concentrating instead on the rational appraisal of evidence involved in large scale cognitive change. This article identifies some of the social dimensions of learning and advocates a teaching approach that is sensitive to the various barriers encountered by a diverse body of students seeking to negotiate access into the subculture of school science.
