This article examines whether religiosity affects Swedish opinion on the European Union (EU) using survey data from 1998 conducted by the SOM Institute, Göteborg University. The findings support the notion that religiosity affects Swedish EU opinion. Members of the free churches (nonconformist Protestants) tend to oppose Swedish EU membership, whereas no such tendency is visible among active members of the Evangelical-Lutheran Church of Sweden (the traditional state church). Members of immigrant churches and adherents to non-Christian religions tend to support Swedish EU membership. The difference between the Church of Sweden and the free churches is explained by the uneven distribution of evangelical values. Support for Swedish EU membership is on the same low level among evangelicals and equally high among mainline Protestants in both religious orientations. Controlling for demographic factors does not change the conclusions. 相似文献

A novel three-dimensional eye tracker is described and its performance evaluated. In contrast to previous devices based on conventional video standards, the present eye tracker is based on programmable CMOS image sensors, interfaced directly to digital processing circuitry to permit real-time image acquisition and processing. This architecture provides a number of important advantages, including image sampling rates of up to 400/sec measurement, direct pixel addressing for preprocessing and acquisition, and hard-disk storage of relevant image data. The reconfigurable digital processing circuitry also facilitatesin-line optimization of the front-end, time-critical processes. The primary acquisition algorithm for tracking the pupil and other eye features is designed around the generalized Hough transform. The tracker permits comprehensive measurement of eye movement (three degrees of freedom) and head movement (six degrees of freedom), and thus provides the basis for many types of vestibulo-oculomotor and visual research. The device has been qualified by the German Space Agency (DLR) and NASA for deployment on the International Space Station. It is foreseen that the device will be used together with appropriate stimulus generators as a general purpose facility for visual and vestibular experiments. Initial verification studies with an artificial eye demonstrate a measurement resolution of better than 0.1° in all three components (i.e., system noise for each of the components measured as 0.006° H, 0.005° V, and 0.016° T. Over a range of ±20° eye rotation, linearity was found to be <0.5% (H), <0.5% (V), and <2.0% (T). A comparison with the scierai search coil technique yieldednear equivalent values for the systemnoise and the thickness of Listing’s plane. 相似文献

Two studies examined individual and environmental forces that affect engagement in prosocial behavior. Self-determination theory was used to derive a model in which autonomy orientation and autonomy support predicted satisfaction of three core psychological needs, which in turn led to engagement in prosocial activities. In Study 1, college students reported their engagement in various prosocial activities, and completed measures of autonomy orientation, parental autonomy support, and general need satisfaction. In Study 2, volunteer workers completed measures of autonomy orientation, work autonomy support and need satisfaction at work. The number of volunteered hours indicated the amount of prosocial engagement. Results across the studies showed that autonomy orientation was strongly related to engagement in prosocial behavior, while autonomy support was modestly related. Need satisfaction partially mediated the effect of autonomy orientation, and fully mediated the effect of autonomy support. Interestingly, autonomy support predicted lower volunteer turnover. Implications for how prosocial behavior can be motivated are discussed. 相似文献

In many previous studies of time-to-contact (TTC) judgments of approaching objects, a response was measured after observers viewed the entire event and was used to infer the informational basis for the judgment. Such measures primarily reflect the information used at the end of the approach event and may not reveal whether observers used different information at different times during the event. Evidence indicates that observers use multiple information sources and that the effectiveness of information varies with distance. We introduce a method in which observers continuously report which of 2 approaching objects would reach them first, throughout the approach. We identified the occurrence and time of response reversals. Most observers changed their relative TTC judgments during the event. The pattern of responses indicated that observers did not use tau early during the approach when objects were far and did not use optical size later when the objects were closer. Most observers relied on either optical size or optical expansion rate early during the approach and expansion rate later during the event, although there were individual differences. A single relative TTC judgment measured after observers view an approach event may not reflect judgments or their informational basis throughout the entire event. 相似文献
