Couples' experiences of daily stress can be detrimental for partners' individual and relational well-being, specifically their identity as a couple, their relational satisfaction, and their life satisfaction. Grounded in the Systemic Transactional Model, this study aimed at analyzing factors that may safeguard partners and their relationship from detrimental effects of internal stress (i.e., stress that originates inside the relationship). We examined the buffering effect of partners' positive dyadic coping and internal problem resolution. Daily diary data were collected across 7 days from 82 heterosexual couples. Multilevel dyadic analyses showed that internal stress was negatively associated with partners' individual and relational well-being. Positive dyadic coping moderated the association between partners' internal stress and couple satisfaction for both partners, but not life satisfaction and couple identity. Moreover, for partners who reported a resolution to the internal problem, the negative associations of internal stress with life satisfaction, couple satisfaction, and couple identity were significantly lower than for those who did not resolve the internal problem. This study confirms the negative role of internal stress on well-being, shows the associations between internal stress and couple identity, and highlights the protective role of dyadic coping and internal problem resolution in couples' daily lives.  相似文献

Pictures of either emotionally neutral, pleasant (affectionate), or unpleasant (threat and injury) scenes were paired with nonemotional control pictures and presented for 3 s, while eye fixations were monitored. Preferential attention to the emotional picture of eah pair occurred at an early processing stage: The probability of placement of the first fixation and the proportion of viewing time during the first 500 ms were higher for both pleasant and unpleasant pictures than for neutral pictures, whereas later fixation location and time were not differentially affected. This suggests that, when emotional and nonemotional stimuli are presented simultaneously, emotional meaning captures initial overt orienting and engages attention early, as measured by gaze direction and duration. The possibility that this effect could be accounted for by perceptual differences—such as luminance and complexity—between emotional and neutral pictures was ruled out.  相似文献

In this paper we discuss inclusiveness of identification among farmers in Galicia (Spain) and The Netherlands. Identification with three nested categories—farmers in the local community, farmers in the country, and farmers in Europe was assessed among 167 Dutch and 248 Galician farmers at three points in time: winter of 1993/94, winter 1995 and fall 1995. Our findings suggest that inclusiveness reduces the level of identification. However, the observed patterns of identification were more complex than inclusiveness per se can account for. Borrowing from the common ingroup‐identity model, functional and socialization models of identity formation, and a model of politicized collective identity we formulated hypotheses about patterns of identification that were to be expected. On the whole our findings supported our theoretical reasoning. Galician farmers appear to identify much less with farmers in their country and Europe than Dutch farmers do. Inclusiveness of identification appears to be linked to experience with national and supranational political institutions. More political knowledge and involvement appear to generate more inclusive patterns of identification. Among Galician farmers evaluation of the agricultural policy of the European Union is negatively related to identification with farmers in Europe, among Dutch farmers the two are positively related. Finally, more inclusive identities seem to be more politicized. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

During the late 19th century and the beginning of the 20th, anarchism represented the most important faction of the radical left in the Atlantic world. This movement attracted a disproportionately high number of Jews. During the same period Buenos Aires became both an important magnet for Jewish immigration and one of the main centers of anarchist activism in the world. This article shows how the Jewish presence in the anarchist movement of the city became, in an amazingly short time and almost ex nihilo, so visible that it turned into a stereotype. The article then attempts to provide an explanation for this phenomenon that relies on a sociological and comparative perspective and questions notions of Jewish exceptionalism and arguments based on the eschatology and ethics of Judaism. Finally, it explores how stereotypes that function at one level as signifiers of alterity and mechanisms of exclusion, can, at another social level, promote acceptance and check anti-Semitism.  相似文献

Intelligent recommendation systems can be based on 2 basic principles: collaborative filters and individual‐based agents. In this work we examine the learning function that results from these 2 general types of learning‐smart agents. There has been significant work on the predictive properties of each type, but no work has examined the patterns in their learning from feedback over repeated trials. Using simulations, we create clusters of “consumers” with heterogeneous utility functions and errorful reservation utility thresholds. The consumers go shopping with one of the designated smart agents, receive recommendations from the agents, and purchase products they like and reject ones they do not. Based on the purchase–no purchase behavior of the consumers, agents learn about the consumers and potentially improve the quality of their recommendations. We characterize learning curves by modified exponential functions with an intercept for percentage of recommendations accepted at Trial 0, an asymptotic rate of recommendation acceptance, and a rate at which learning moves from intercept to asymptote. We compare the learning of a baseline random recommendation agent, an individual‐based logistic‐regression agent, and two types of collaborative filters that rely on K‐mean clustering (popular in most commercial applications) and nearest‐neighbor algorithms. Compared to the collaborative filtering agents, the individual agent (a) learns more slowly, initially, but performs better in the long run when the environment is stable; (b) is less negatively affected by permanent changes in the consumer's utility function; and (c) is less adversely affected by error in the reservation threshold to which consumers compare a recommended product's utility. The K‐mean agent reaches a lower asymptote but approaches it faster, reflecting a surprising stickiness of target classifications after feedback from recommendations made under initial (incorrect) hypotheses.  相似文献

The reality of illusory conjunctions in perception has been sometimes questioned, arguing that they can be explained by other mechanisms. Most relevant experiments are based on migrations along the space dimension. But the low rate of illusory conjunctions along space can easily hide them among other types of errors. As migrations over time are a more frequent phenomenon, illusory conjunctions can be disentangled from other errors. We report an experiment in which series of colored letters were presented in several spatial locations, allowing for migrations over both space and time. The distribution of frequencies were fit by several multinomial tree models based on alternative hypothesis about illusory conjunctions and the potential sources of free-floating features. The best-fit model acknowledges that most illusory conjunctions are migrations in the time domain. Migrations in space are probably present, but the rate is very low. Other conjunction errors, as those produced by guessing or miscategorizations of the to-be-reported feature, are also present in the experiment. The main conclusion is that illusory conjunctions do exist.  相似文献

There are two standard theoretical responses to putative errors in ordinary thinking about some given target property: eliminativism or revisionism. Roughly, eliminativism is the denial that the target property exists, and revisionism is the view that the property exists, but that people tend to have false beliefs about it. Recently, Shaun Nichols has proposed a third option: discretionism. Discretionism is the idea that some terms have multiple reference conventions, so that it may be true to say with eliminativists that the property does not exist, and true to say with revisionists (and others) that the property does exist. This article explores the viability of discretionism, and argues that it faces serious difficulties. Even if the difficulties faced by discretionism can be overcome, it is unclear that discretionism secures anything beyond what is already available to standard revisionist views. The article concludes with some reflections about Nichols’ account of the bare retributive norm.  相似文献

Several studies have consistently linked the Evangelical breakdown in Latin America as a mass movement mainly adopted by impoverished working class individuals. However, little is known about how religious inheritance and recruitment of Evangelical movements is affected when status conditions improve along individuals trajectories. Using Bicentenario Survey from 2006 to 2010 we analyze how intergenerational patterns of religious persistence in Chile relate to individuals’ educational attainment and intergenerational mobility. Two mechanisms are evaluated: first, the intergenerational persistence of Evangelicals compared to Catholics and “None’s”; and second, the probability of conversion or reaffiliation to Evangelical Protestantism. Multinomial regression analysis shows that the greater an individual’s educational credentials and upward mobility, the lesser their identification with Evangelical movements, regardless of their religious affiliation or educational attainment of origin. This evidence suggests there are obstacles for Evangelical movements’ vertical mobility, which could be related to Chile’s strong social cleavage in terms of religion.  相似文献
