At the time of this writing, a widely publicized, waived-consent trial is underway. Sponsored by Northfield Laboratories, Inc. (Evanston, IL) the trial is intended to evaluate the emergency use of PolyHeme, an oxygen-carrying resuscitative fluid that might prevent deaths from uncontrolled bleeding. The protocol allows patients in hemorrhagic shock to be randomized between PolyHeme and saline in the field and, still without consent, randomized between PolyHeme and blood after arrival at an emergency department. The Federal regulations that govern the waiver of consent restrict its applicability to circumstances where proven, satisfactory treatments are unavailable. Blood-the standard treatment for hemorrhagic shock-is not available in ambulances but is available in hospitals. The authors argue that the in-hospital stage of the study fails to meet ethical and regulatory standards.  相似文献

Subjects were shown two letters from the set BDGbdg. In one condition, subjects were required to decide whether or not the letters had the same name. In the other condition, subjects decided whether or not the two letters were presented in the same case. Reaction times were always faster when the two letters on a given trial were physically identical. However, there was no difference in the speed of a name match or a case match when the two letters were not physically identical. Since subjects could have based a case match on the presence or absence of a single feature — a protruding vertical line — it was concluded that subjects are not able to selectively attend to a single visual feature in order to identify a letter. Rather, a subject analyzes several features in parallel in order to arrive at a simultaneous decision about a letter's name or case.  相似文献

A confusion matrix of the whole block capital letters of the alphabet was obtained so as to examine the nature of tactile letter recognition, using a 17 by 17 matrix of tactile stimulators placed against blind subjects’ backs. A hierarchical cluster analysis and a nonmetric multidimensional scaling technique were applied to the matrix. The results of the two analyses were consistent with each other and indicated that at least three independent basic letter features—enclosing shapes, vertical parallel lines, andangle of lines—play important parts in tactile letter recognition. Most confusion may be attributable to displacement of the apparent loci, omission or fusion of loci of stimulation, and failure to detect gaps in the tactile letters.  相似文献

宗教资本:从布迪厄到斯达克   总被引:1,自引:0,他引:1  
"宗教资本"概念对理性选择理论的发展至关重要,然而,"宗教资本"的诸多定义却常常模糊不清,或脱离于其所源出的知识构架。关于"宗教资本"概念,有两种相互独立发展的理论:其一大致属于欧洲,源自韦伯和布迪厄的研究;其二大致属于美国,源自艾纳孔和斯达克的研究。泰瑞·雷对通过对两种理论的比较研究,进而厘清其理论谱系,仔细考察了宗教资本概念及其衍生概念"灵性资本"的应用和批评,并提出了两个具有独创性的修正概念("制度宗教资本"和"民间宗教资本"),以此解决宗教资本概念在学术著作和文章中所出现的问题。  相似文献

In what seems to be a response to a paper by Skinner (1987), Mahoney (1989) provides evidence of unfamiliarity with and intellectual intolerance toward radical behaviorism by presenting a critique of it that includes a variety of improper and counterfactual attributions. For example, he argues that radical behaviorism is Cartesian rather than Baconian when the historical record shows the opposite, that it is fundamentally associationist when in fact it is selectionist, and that its philosophy of science is essentially that of operationalism and logical positivism when instead it moved on to other criteria decades ago. The details of Mahoney's history are sometimes flawed and sometimes unsubstantiated, as when he provides a distorted account of the origins of the Association for Behavior Analysis or when he makes undocumented claims about the banning of books. On examination, many of his arguments are couched in stylistic terms that share their rhetorical features with racial, ethnic, and religious stereotyping.  相似文献

While there has been increasing effort in dissociating the neural substrates recruited by perception of different objects, the theoretical and behavioural work needed to understand such dissociation lags behind. In an attempt to compare expertise in letter and face perception, we outline a theoretical framework that characterizes different types of object expertise based on the task demand (level of abstraction) required in object categorization. Face perception requires categorization at a subordinate level, whereas letter perception involves mainly basic-level categorization. Accordingly face and letter perception should represent two different types of expertise and display different neural and behavioural markers. Results from three behavioural experiments supported the predictions of the framework in that letter expertise is characterized by an enhancement of the basic-level advantage, instead of its attenuation as typically found for face perception. We compare this framework with Farah's taxonomy of visual abilities based on cooccurrence of deficits in visual agnosias.  相似文献
