How can the history of research ethics be expanded beyond the standard narrative of codification—a story that does not reach back beyond World War II—without becoming so broad as to lose all distinctiveness? This article proposes a history of research ethics focused on the “scientific self,” that is, the role-specific identity of scientists as typically described in terms of skills, competencies, qualities, or dispositions. Drawing on three agenda-setting texts from nineteenth-century history, biology, and sociology, the article argues that the “revolutions” these books sought to unleash were, among other things, revolts against inherited conceptions of scientific selfhood. They tried to redefine the scientific self in their respective fields of inquiry by advocating particular catalogs of virtues or character traits. These ideals of selfhood, their contested nature notwithstanding, translated into practice in so far as they influenced hiring and selection policies and found their way into educational systems. The project of reclaiming the scientific self as an important subject of study in the history of research ethics is not an antiquarian pursuit, but related to an ethical question faced by scientists today: How are their scientific selves being shaped by funding schemes, research evaluation protocols, and academic hiring policies? 相似文献

When children are in the process of learning their mother tongue, they show frequent use of nonfinite clauses, even though they produce finite clauses at the same time, thereby demonstrating the availability of the functional domain associated with finiteness. In this study the hypothesis was tested that this behavior results from an overuse of the normal elliptical repertoire that has also been observed in agrammatic aphasia. The purpose of this overuse is prevention of computational overload. In support of the hypothesis it was found that children behaved very similar to aphasics and normal adults with respect to the following parameters: (a) distribution of types of ellipsis, (b) elaboration of ellipses, (c) word order, (d) subject omission, (e) frequency of weak subject pronouns, and (f) verb type (eventivity). The results also support the Jackson/Jakobson regression hypothesis, at least at the grammatical level. 相似文献

Several brief preference assessments have recently been developed to identify reinforcers for individuals with developmental disabilities. One purported advantage of brief assessments is that they can be administered frequently, thus accommodating shifts in preference and presumably enhancing reinforcement effects. In this study, we initially conducted lengthy paired‐choice preference assessments and identified a hierarchy of preferred items for 5 individuals with developmental disabilities. Subsequently, brief multiple‐stimulus‐without‐replacement assessments using the same items were completed each day prior to work sessions. On days when results of the daily brief assessment differed from the one‐time lengthy assessment, the relative reinforcing effects of the top items from each assessment were compared in a concurrent‐schedule arrangement. The results revealed that when the two assessments differed, participants generally allocated more responses to the task associated with the daily top‐ranked item. 相似文献

We refine our Boundary Model of the regulation of drug intake and apply it to several examples from cigarette smoking. Our model demands the simultaneous consideration of biological and psychosocial controls. The biological factors include the physiological demand to maintain minimum levels of nicotine, direct rewarding effects of tobacco, and toxic effects of excessive smoking. The psychosocial factors include “voluntary”, self-initiated controls as well as situational influences. In light of the model, we review and consider the problems with techniques commonly used to control smoking, and we discuss the inferential confusions faced by smokers and researchers. 相似文献

Second graders (mean age = 7-8), fourth graders (mean age = 9-8), and sixth graders (mean age = 11-11) walked two paths located in and around their school. Children in the Unsegmented condition estimated the distance and time taken to walk a path that was relatively undifferentiated in terms of the number of qualitatively different areas of the school through which it passed. Children in the Segmented condition made the same estimates for a path that went through different areas (segments) of the school (i.e., cafeteria, hall, vestibule, and outside the building). Children at all three grade levels estimated that the distance traversed in the Segmented condition was longer than the distance in the Unsegmented condition. This difference was not significant on the time measure. It was concluded that (1) paths with a large number of segments are perceived as being longer than paths of the same length with fewer segments, (2) distances along paths with few segments are underestimated, (3) distances along paths with many segments may be overestimated as a function of developmental level, and (4) only younger children may have used time to estimate distance. 相似文献

To test if stressful anticipation of speech situations is a factor in eliciting stuttering behavior, the difference between 24 stutterers and 24 nonstutterers in verbal apprehension and physiologic activity was studied before and during speech tasks (reading and conversation), and nonspeech tasks (motor and intelligence task).Results indicate that the difference between stutterers and nonstutterers mainly were restricted to anxiety ratings assessed after each task. Heart rate, vasomotor responses, and electrodermal activity recorded before and during speech tasks were higher compared with the physiologic activity before and during nonspeech tasks but, unexpectedly, this was also the case for nonstutterers. It is concluded that stuttering is not elicited by anxiety. 相似文献

Schotte (1992) argued that ego threat is not a necessary precondition for the disinhibition of eating in dieters. This article agrees that there are indeed other triggers for disinhibition, as has long been widely acknowledged, but also argues that when distress does act as a trigger for disinhibition, it does so by threatening the dieter's self-image. 相似文献
