Research indicates that personal interests drive news consumption, such that individuals neglect news items that are not of obvious personal relevance. This study tested whether an extrinsic social goal might increase personal interest in news through increased acquisition of, and perceived attention to news information, irrespective of pre-existing interest in the given topic. Results showed the prime increased information acquisition, as well as perceived attention to news. The prime also worked directly and indirectly through perceived attention to influence news interest in the predicted direction. Applications of findings for news teases and other promotional messages are considered. 相似文献

中国农业在中国农政管理系统中是治国之本,该系统兼容地方文化多样性,扎根社会网络,对科学、技艺、技术的知识与实践产生了积极作用。在19世纪之前,几乎没有任何西方国家在促进农业生产和传播农业知识方面有所作为,中国却从宋代开始已经全面着手,政府发挥各级官员、文人学士、地主作者、农民和工匠的综合作用,鼓励官民合作,发展先秦以来的儒家伦理政治、伦理社会秩序和伦理道德民俗,更新了中国农业国家的知识系统与宇宙观。发展这一方向的研究成果,能够增加我们对科学与规律的理解,而它不仅存在于中国,也普遍地存在于人类社会的前现代时期之中。 相似文献

This study compares the effects on Mental Rotation Test (MRT) performance of instructions that stress the importance of (a) personal effort, and (b) genetically driven ability. A total of 120 high-school students were assigned to three groups, and administered two sub-tests of the MRT. Between the first and second sub-tests, the groups received one of the following instructions: effort (“anyone can succeed in this task by putting in effort”), ability (“performance on the test depends on genetic determinants”), and neutral for control (“this is an important test used in many countries”). We predicted that effort but not ability instructions would affect performance. Results confirmed the prediction and showed that, after controlling for baseline performance, the effort group outperformed the ability and control groups, which did not differ from each other. Discussion focuses on the mechanisms implied in believing ability to be genetically determined or experientially driven. 相似文献

The influence of chemical treatments based on novel organic products on the consolidation of deteriorated wood by insect attack was evaluated on two hardwoods and one softwood: fir (Abies alba), beech (Fagus sylvatica) and deciduous oak (Quercus sp.). Degraded and intact specimens of the three wood species were impregnated with two different chemical treatments aimed to verify the potential synergic action of the novel products on wood. Then, the specimens were subjected to bending, compression parallel to the grain, impact, hardness and water absorption tests. Untreated specimens of the same botanical species, both degraded and non-degraded, were examined for comparison purposes. The experimental results showed a different effectiveness of the proposed chemical treatments to improve the mechanical and absorption properties of degraded wood. The most effective treatment was the one assuming the concurrent use of the studied novel consolidants. The species more susceptible of the enhancement in mechanical properties were fir and beech. The observed differentiations were most likely caused by the different structure of the botanical species considered, leading to a consequent different product penetration in the wood structure. The dimensional stability in terms of water repellent and antiswelling efficiency, after a three-month immersion in deionized water, was found to improve in all the treated wood specimens. Overall, experimental results showed that the impact of the chemical treatments was higher on degraded samples than on intact ones. 相似文献

This article presents the pseudo-equivalent group approach and discusses how it can enhance the quality of linking in the presence of nonequivalent groups. The pseudo-equivalent group approach allows to achieve pseudo-equivalence using propensity score reweighting techniques. We use it to perform linking to establish scale concordance between two assessments. The article presents Monte-Carlo simulations and a real data application based on data from the Survey of Adult Skills (PIAAC) and the Programme for International Student Assessment (PISA). Monte-Carlo simulations suggest that the pseudo-equivalent group design is particularly useful whenever there is a large overlap across the two groups with respect to balancing variables and when the correlation between such variables and ability is medium or high. The example based on PISA and PIAAC data indicates that the approach can provide reasonable accurate linking that can be used for group-level comparisons. 相似文献

The susceptibility to gaze cueing in deaf children aged 7–14 years old (N = 16) was tested using a nonlinguistic task. Participants performed a peripheral shape-discrimination task, whereas uninformative central gaze cues validly or invalidly cued the location of the target. To assess the role of sign language experience and bilingualism in deaf participants, three groups of age-matched hearing children were recruited: bimodal bilinguals (vocal and sign-language, N = 19), unimodal bilinguals (two vocal languages, N = 17), and monolinguals (N = 14). Although all groups showed a gaze-cueing effect and were faster to respond to validly than invalidly cued targets, this effect was twice as large in deaf participants. This result shows that atypical sensory experience can tune the saliency of a fundamental social cue. 相似文献

The microclimatic analysis of the Petrarca's tomb in Arquà Petrarca, Padua (Italy) was performed to assess the suitability of a closed environment located outdoors respect to the conservation requirements of heritage materials. Results showed that the thermo-hygrometric conditions inside the tomb were not suitable for the conservation of organic materials, like bones and wood. The orientation (north or south) was the main responsible for the different damage features of the two sides of the wooden case housing the human remains inside the tomb. Technical solutions were finally implemented to improve the conservation conditions, thus avoiding further damage. 相似文献

This paper investigates the interaction between technological and organizational parameters. Recent studies have been focused on the information and communication impact on organizational parameters, owing to the growing need to acquire and process information. We focus on the impact of the content management system on publishing firms and through the study of ten Italian cases we identify the socio-technical context which favor the adoption of technology as well as the organizational parameters influenced by the technology use. 相似文献
