This paper describes a circuit that allows multiple-unit neural activity to be converted to standardized pulses for computer data acquisition. Positive or negative spikes can be converted at any voltage level from positive 25 V to. negative 25 V with visual identification of exactly where on the amplified spike potential conversion occurs. This circuit provides active output voltages compatible with TTL logic. 相似文献

A limited number of accounts of near-death visions that include unborn children suggest a life before birth. The unborn children in these visions have been described as spirits, as children or children but full-grown, and as residing in another world, perhaps different from the realm of the afterlife. The arrival of these children into our earthly world is similar to the departure of near-death experiencers into the other world. 相似文献

The literature on near-death experiences (NDEs) contains no substantive discussion of angels in NDEs, even though there are references to angels in several studies of these experiences. In this article I identify angels in NDEs and describe their functions in the NDE based on published NDE accounts. I conclude that angels are personages with whom the NDEr does not usually recall having previous acquaintance. Angels, serve as guides, messengers, or escorts in the NDE.This research was supported by a sabbatical leave granted by the Sabbatical Leave Commitee of Western New Mexico University. 相似文献

A general purpose input-output interface is an essential tool in many common research situations. This article describes a simple way to set up the IBM-compatible microcomputer’s RS-232 serial port as an interface with up to four inputs and two outputs. First, aspects of the serial port relevant to its use as an input-output interface are discussed. Next, port access commands needed to control output lines and monitor input lines in the appropriate way are described, and examples in the Turbo Pascal 5.0 language are provided. Finally, a schematic diagram and a discussion of a simple circuit to implement the interface are provided. 相似文献

The effect of television day part on gender portrayals in television commercials: A content analysis
R. Stephen Craig 《Sex roles》1992,26(5-6):197-211
Gender portrayals in 2,209 network television commercials were content analyzed. To compare differences between three day parts, the sample was chosen from three time periods: daytime, when the audience is mostly women; evening prime time, when the sex of the audience is more evenly distributed; and weekend afternoon sportscasts, when men are a large percentage of the audience. The results indicate large and consistent differences in the way men and women are portrayed in these three day parts, with almost all comparisons reaching significance at the .05 level. Although ads in all day parts tended to portray men in stereotypical roles of authority and dominance, those on weekends tended to emphasize escape from home and family. The findings of earlier studies which did not consider day part differences may now have to be reevaluated. 相似文献

Abstract. This paper uses an evolutionary perspective to identify variables influencing compliance with moral codes about honest communication. Data on over one thousand radio conversations among lobster fishers in two harbors in Maine are compared in regard to the sharing of information. The sharing of accurate information is found to be significantly more frequent in the harbor that is more integrated by reciprocally altruistic relationships. This is consistent with the view that moral systems are systems of indirect reciprocity, but it also suggests that humans have evolved to base their compliance with moral codes on cues from their social environment. 相似文献

Social and cognitive psychologists have conceptualized judgemental confidence (how strongly a person holds the belief that some judgement is correct) as being proportional to the amount of evidence in favour of a response. Festinger (1950) argued that there are two separate processes by which uncertainty (the inverse of confidence) can be reduced. These two processes are physical reality testing (the perceptual processing of stimulus information) and social reality testing (reliance on other people to resolve particularly ambiguous situations). However, there is surprisingly little direct evidence that uncertainty is either reduced or increased by the responses of other people. In two experimental tests (N = 74 and N = 83) it was found that disagreement increased uncertainty and agreement tended to reduce uncertainty. In a third experiment (N = 63) it was found that disagreement only increased uncertainty when stimulus information was limited, but that agreement generally reduced uncertainty. The results challenge Festinger's model of uncertainty reduction and support a self-categorization theory account. 相似文献

This article describes the social positions of inhabitants in the otherworldly City of Light as reported by a limited number of Mormon near-death experiences (NDErs). These social positions included men and women and various relatives and friends, in addition to authorities or administrators, genealogists, guardians, guides, homemakers, missionaries, teachers, and students. These reports of social positions in the City of Light are similar to those described by other researchers, and are comparable to those found in our own world.The authors thanks Jay G.Burrup for providing a section of theDiary of George Henry Carver.

Weighted additive evaluation functions are widely used to rank alternatives in decision making under certainty with multiple evaluation attributes. Some researchers have suggested that approximate attribute weights may be adequate to accurately rank alternatives. Use of approximate weights would simplify decision analysis since detailed elicitation of weights can be time consuming and controversial. This article investigates the degree to which partial information about the relative magnitudes of attribute weights is sufficient to rank alternatives as a function of the number of decision alternatives, the number of attributes, and the number of allowed levels for each attribute. A simulation analysis, as well as a reanalysis of an actual application, shows that partial information about weights is often not sufficient to determine the most preferred alternative for realistic decision problems. Hence, approximation procedures for specifying weights may lead to errors. However, our work also shows that a simple analysis procedure can be used to accurately determine whether partial information about weights is adequate to correctly specify the most preferred alternative. This procedure can be useful for identifying situations in which detailed elicitation of weights is not needed. 相似文献

The range and utility of the MMPI-derived MacAndrew Alcoholism Scale (MAC) and the Heroin Addiction Scale (He) was assessed with a large sample of drug addicts with and without concurrent alcoholism. Results indicated that addicts with a co-existing alcohol problem obtained higher MAC scores than addicts without a current alcohol problem. Opiate abusers scored higher on the MAC than non-opiate abusers. No such effects were observed with the He scale. The MAC is a particularly robust scale that taps generic substance abuse and may even be sensitive enough to detect alcoholism in drug addicts. 相似文献
