Textbooks provide a rich site within which to investigate how members of a scientific discipline choose to represent their research to general audiences. We used critical contextual empiricism as a framework for interrogating how a scientific community is depicted via images in evolution textbook chapters on sexual selection. Textbooks that exhibit science within the tenets of critical contextual empiricism will depict uptake of disciplinary change and acknowledge the inseparability of the social and rational aspects of scientific knowledge construction. Sexual selection is an exemplary arena for this work because the field has undergone substantial change in the past few decades that has been driven by critique from within and among disciplines. We used quantitative methods and content analysis to examine images from the textbook editions and from a time series of editions to examine the portrayal of updated understandings of sexual selection. We found that most textbook images did not reflect the shift happening in the scientific community. Images highlighted primarily the classic view of sexual selection focused on males. Examples typical of a more realistic, complicated understanding received little attention even though the scientific literature on these topics appeared decades before these textbooks were published. Images of males were more common than images of females, females were depicted for fewer concepts than males, and images of males and females reinforced stereotypical sex roles. This study highlights an opportunity for acknowledging the inseparability of the social and the rational in scientific knowledge construction. 相似文献

The Web has evolved as a hypertext environment whose value is derived from a simple ability to link resources together. The advanced linking features of some early hypertext systems might be implemented in the Web in various ways. The Semantic Web is one aspect of the continuing evolution of the Web which may be of value to the evolution of scholarly publishing and research, and may enable publishers to justify investment in the future. The key advantages are the ability to unlock value from the existing scholarly literature by enabling innovation in research tools; further encouraging the creation of a marketplace of services of value to the publishing industry; and ensuring that websites and content are well integrated into the Web as it exists now and in the future. 相似文献

This article presents the results of a systematic review of the literature surrounding the effects that acute sleep deprivation has on metacognitive monitoring. Metacognitive monitoring refers to the ability to accurately assess one’s own performance and state of knowledge. The mechanism behind this assessment is captured by subjective feelings of confidence concerning the accuracy of our judgments or performance. These judgments influence decision behavior. How well these subjective feelings fit with reality is critical for good decision making. For example, a driver who is overconfident in their ability to remain vigilant after a night without sleep is at risk of having an accident. A learner who is overconfident in their ability to perform well on an exam without sleep is at risk of failing. A break down in metacognitive monitoring might be responsible for the increase in poor decision making observed when people are sleep deprived. Using defined search terms and exclusion criteria, electronic database searches identified ten empirical studies suitable for review. Participants in these studies completed performance-based tasks, typically cognitive, while remaining awake for 28–63 hours. In all studies, metacognitive monitoring was assessed via confidence ratings either pre-, on-, or post-task. Extended wakefulness had a significant negative effect on performance in most studies. Evidencing good monitoring, however, the monitoring estimates such as confidence also tended to decline. Moreover, two critical variables that assess the fit of these estimates to actual performance (bias and discrimination) were mostly unaffected by the number of hours awake. Still, some results indicated that these variables may be affected by substances intended to fight sleep deprivation, such as modafinil. Within the limitations of extant literature (e.g., a sampling bias towards young adult male participants), empirical observations to date converge to suggest that metacognitive monitoring remains largely unaffected by the examined quantities of acute sleep deprivation (up to 63 hours). 相似文献
