That vaccines do not cause autism is now a widely accepted proposition, though a few dissenters remain. An 8-year court process in the US federal vaccine injury compensation court ended in 2010 with rulings that autism was not an adverse reaction to vaccination. There were two sets of trials: one against the measles-mumps-rubella (MMR) vaccine and one against the mercury-based preservative thimerosal. The MMR story is more widely known because of publicity surrounding the main proponent of an MMR-autism link, British doctor Andrew Wakefield, but the story of thimerosal in court is largely untold. This study examines the credibility battles and boundary work in the two cases, illuminating the sustaining world of alternative science that supported the parents, lawyers, researchers, and expert witnesses against vaccines. After the loss in court, the families and their advocates transformed their scientific arguments into an indictment of procedural injustice in the vaccine court. I argue that the very efforts designed to produce legitimacy in this type of lopsided dispute will be counter-mobilized as evidence of injustice, helping us understand why settling a scientific controversy in court does not necessarily mean changing anyone's mind. 相似文献

This paper discusses three related examples of mission-oriented agricultural institutional innovations associated with substantial crop yield increases in the 20th century. It begins with the implementation of the United States Land-Grant System and then discusses in turn the planning and implementation of the two grand missions that led successively to the yield increases in wheat and rice that heralded the onset of the “Green Revolution.” It notes the remarkable role of the Rockefeller Foundation in identifying these two missions, and selecting personnel developed within the land-grant system to execute them with remarkable effectiveness. 相似文献

This paper addresses the challenge of striking a balance between, on one hand, mitigating uncertainty through the existence of systematic processes and structures and, on the other, stimulating creativity through allowable variation in work processes and structures. Both objectives are fundamental aspects of product development work. Our main finding is that both objectives can be achieved simultaneously. We introduce trust as a mediating variable. We show first, that being systematic in the processes for obtaining information and applying explicit organizational rules and structures in product development work creates an atmosphere of trust in the organization. Second, we show that trust increases creativity. The paper contributes to an understanding of how and why trust is important in product development organizations and of how trust can be actively managed. Above all, the paper contributes to the understanding of how uncertainty and creativity should be managed in organizations conducting product development. 相似文献

The seismic assessment of art objects requires a multidisciplinary approach and the definition of a specific methodology for evaluating the level of safety and the possible interventions necessary for seismic risk prevention, finding a compromise between safety and conservation. This paper describes a first step in this direction, in which the different aspects of the procedure, from knowledge path of the art object to the structural analysis, were studied in the six Michelangelo's statues located in the “Galleria dei Prigioni” (Slaves’ Gallery) at the Accademia Gallery of Florence. We showed that the general principles and criteria expressed in the “Italian Guidelines for evaluation and mitigation of seismic-risk to cultural heritage”, which are specifically devoted to masonry constructions, could be profitably extended to other artworks, like statues, starting from historical research, geometrical survey and material characterization, up to the developing of specific methods of analysis. This research could be the base for future studies to be performed concerning the prevention of seismic damage of art objects, including both bare minimum interventions and specific devices, such as isolation systems. 相似文献

Kindergarten risk factors, cognitive factors, and teacher judgments as predictors of early reading in Dutch 总被引:1,自引:0,他引:1
This study focused on the predictive value of risk factors, cognitive factors, and teachers' judgments in a sample of 462 kindergartners for their early reading skills and reading failure at the beginning of Grade 1. With respect to risk factors, enrollment in speech-language therapy, history of dyslexia or speech-language problems in the family, and the role of gender were considered. None of these risk factors were significantly related to reading performance. Cognitive factors in this study included letter knowledge, rapid naming ability, and nonword repetition skills. Of these skills, letter knowledge seemed to have the highest correlation with reading. Kindergarten teachers' judgments, including a task assignment scale and teachers' predictions, demonstrated a significant relationship with reading. Finally, to judge whether these predictors could identify reading disabilities, the discriminatory power of all predictors was assessed and appeared to be insufficient. Implications for screening purposes are discussed. 相似文献

Lexical-decision studies with experienced English and French readers have shown that visual-word identification is not only
affected by pronunciation inconsistency of a word (i.e., multiple ways to pronounce a spelling body), but also by spelling
inconsistency (i.e., multiple ways to spell a pronunciation rime). The aim of this study was to compare the reading behavior
of young Dutch readers with dyslexia to the behavior of readers without dyslexia. All students participated in a lexical-decision
task in which we presented pronunciation-consistent words and pseudowords. Half of the pronunciation-consistent stimuli were
spelling consistent and the other half were spelling inconsistent. All three reader groups, that is, students with dyslexia,
age-match students, and reading-match students, read spelling-consistent words faster than spelling-inconsistent words. Overall
reading speed of students with dyslexia was similar to that of reading-match students, and was substantially slower than that
of age-match students. The results suggest that reading in students with or without dyslexia is similarly affected by spelling
inconsistency. Subtle qualitative differences emerged, however, with respect to pseudoword identification. The conclusion
was that the findings were best interpreted in terms of a recurrent-feedback model. 相似文献

Partnerships with parents, particularly in the field of education, have featured prominently in policy rhetoric for many years, but routes of redress have not had much attention until relatively recently. The development of Alternative Dispute Resolution in the UK reflects the situation in several jurisdictions (e.g. Norway, Germany, the Netherlands) where citizens can choose not to go to court to resolve administrative disputes. Under the Education (Additional Support for Learning [ASL]) (Scotland) Act 2004 local authorities must establish and publicise procedures for identifying and meeting the needs of children requiring additional support for learning. The Act and Code of Practice advocate early intervention to prevent disagreements about the provision for additional support from escalating into more serious disputes, with local authorities required to provide information about, and access to, independent mediation for parents. In Scotland the ASL Act 2004 has resulted in four routes available for redress in the area of Additional Support Needs which include both mediation and litigation type processes: ? Informal mediation ? Formal mediation ? Adjudication ? Tribunal This article uses case study information from parents in three local authorities in Scotland to explore why independent mediation is being under-used by schools and parents, and what factors influence this. Questions are raised regarding the large numbers of parents who are unaware of mediation, the attitudes towards and use of independent mediation by local authorities and the suitability of independent mediation, particularly when the dispute is over resources. 相似文献

We explore the utility of George Kelly's Personal Construct Theory, specifically his repertory grid technique, to the assessment of student learning in undergraduate science courses. We provide an in-depth review of the assumptions underlying Personal Construct Theory and how these were reflected in the repertory grid technique Kelly developed. We explain how an adapted version of the repertory grid, sharing some yet not all of Kelly's assumptions, was utilised as a research tool in a recent study involving science instructors and their students. We argue that as well as having applicability as an innovative research tool, an adapted version of Kelly's repertory grid is a useful heuristic for university teachers when used as a classroom assessment technique (CAT) and indicate several features it shares with the more widely-known conceptual mapping technique, which has been used in the study of science teaching and learning for many years. We conclude by highlighting several advantages the use of repertory grids has for both students and instructors. 相似文献
