I examine the value and limitations of Kuhn’s Structure of Scientific Revolutions. In the interests of developing a social epistemology of science, I argue that we should draw on Kuhn’s later work, published in The Road since Structure. There, Kuhn draws attention to the important role that specialty formation plays in resolving crises in science, a topic he did not discuss in Structure. I argue that we need to develop a better understanding of specialty research communities. Kuhn’s later work provides a research agenda for those who want to study scientific specialization. I briefly discuss some recent studies that promise to provide valuable insight into the social structure of science. 相似文献

This study examined ratings of fourth graders’ oral reading expression. Randomly assigned participants (n = 36) practiced repeated readings using narrative or informational passages for 7 weeks. After this period raters used the Multidimensional Fluency Scale (MFS) on two separate occasions to rate students’ expressive reading of four equivalent passages. Results of this generalizability study showed that a minimum of two and preferably three equivalent passages, two raters, and one rating occasion are recommended to obtain reliable ratings. This research substantiates the reliability of the MFS and demonstrates the importance of raters collaborating and finding texts at students’ independent reading levels. 相似文献

Four studies present the first evidence showing that public (vs. private) provocation augments triggered displaced aggression by increasing the perceived intensity of the provocation. This effect is shown to be independent of face‐saving motivation. Following a public or private provocation, Study 1 participants were induced to ruminate or were distracted for 20 min. They then had an opportunity to aggress against another person who either acted in a neutral or mildly annoying fashion (viz. triggering event). As expected, the magnitude of the greater displaced aggression of those who ruminated before the triggering event compared with those distracted was greater under public than private provocation. Study 2 replicated the findings of Study 1 and confirmed that public provocations are experienced as more intense. Studies 3 and 4 both manipulated provocation intensity directly to show that it mediated the moderating effect of public/private provocation found in Study 1. The greater intensity of a public provocation increases reactivity to a subsequent trigger, which in turn, augments triggered displaced aggression. Aggr.

If counterfactual dependence is sufficient for causation and if omissions can be causes, then all events have many more causes than common sense tends to recognize. This problem is standardly addressed by appeal to pragmatics. However, Carolina Sartorio [2010] has recently raised what I shall argue is a more interesting problem concerning omissions for counterfactual theories of causation—more interesting because it demands a more subtle pragmatic solution. I discuss the relationship between the idea that causes are proportional to their effects, the idea that causation is contrastive, and the question of the dimensions along which causal explanations should be evaluated with respect to one another. 相似文献

ABSTRACT This article reports on the use of a post-visit web survey to assess how visitor reactions to the exhibition Sharks: Myth and Mystery at the Monterey Bay Aquarium. The web survey was used to supplement on-site observations and interview data. A total of 598 visitors shared their e-mail addresses with the aquarium so they could participate in the survey, and 61% of successfully delivered e-mails elicited responses yielding 314 completed surveys. Results from the web survey showed that visitors could recall specific aspects of the exhibition four months after their visit, with more than one-third (37%) of visitors able to cite an occurrence in their day-to-day lives that had reminded them of the exhibition. In addition, the majority of visitors (59%) recalled speaking to someone else about the exhibition since their visit. When prompted, many visitors (44%) were also able to recall specific conservation content presented in the exhibition. This case study demonstrates that web surveys can provide the field of visitor studies with a viable method for gathering post-visit data and highlights additional design tips for evaluators. 相似文献

The catalyst model suggests that adult criminality arises from the interaction of genetic and proximal social influences such as family influences, but that distal social influences such as media exposure have only negligible influence. This article uses data from a 13-year longitudinal study of adolescent health to examine the catalyst model. As expected by the catalyst model, adult criminality was best explained by a confluence of genetic and proximal social risk factors. The influence of media exposure on adult criminality was negligible. Implications of these findings for both theory and policy are discussed. 相似文献

Many laboratory studies of aggression use a measure known as the modified Taylor Competitive Reaction Time Test (TCRTT), for which validation studies are lacking. Using sound blasts administered by the participant against a fictional human opponent, the TCRTT also allows for multiple methods of measuring aggression. The validity of the TCRTT was tested in 53 college student participants. Participants took a self-report measure of aggressiveness as well as neuropsychological measures of frontal lobe functioning predictive of aggression. Results were not supportive of the TCRTT's validity and indicated concerns regarding the use of the TCRTT as a measure of aggression. Results suggest that labaratory studies of media violence using the TCRTT are of questionable validity. 相似文献

Research on the leadership of executives in the United States typically follows one of two traditions, emphasizing either characteristics of the incumbent or features of the office. This article brings together these traditions. It draws upon the work of Winter to develop measures of three aspects of personality—the power, achievement, and affiliation drives—and hypothesizes that the power and achievement motives are exhibited in conjunction by successful chief executives. It then tests this hypothesis within the contexts of the American states, thus accounting for both the leaders as individuals and the features of the political and economic environments in which they lead. The primary hypothesis is affirmed. Governors who exhibit high levels of the power and achievement motives in tandem are substantially more likely to achieve their policy goals. In addition, governors who emphasize affiliation are less successful. 相似文献

Classic deductive logic entails that once a conclusion is sustained by a valid argument, the argument can never be invalidated, no matter how many new premises are added. This derived property of deductive reasoning is known as monotonicity. Monotonicity is thought to conflict with the defeasibility of reasoning in natural language, where the discovery of new information often leads us to reject conclusions that we once accepted. This perceived failure of monotonic reasoning to observe the defeasibility of natural-language arguments has led some philosophers to abandon deduction itself (!), often in favor of new, non-monotonic systems of inference known as `default logics'. But these radical logics (e.g., Ray Reiter's default logic) introduce their desired defeasibility at the expense of other, equally important intuitions about natural-language reasoning. And, as a matter of fact, if we recognize that monotonicity is a property of the form of a deductive argument and not its content (i.e., the claims in the premise(s) and conclusion), we can see how the common-sense notion of defeasibility can actually be captured by a purely deductive system. 相似文献
