信息需求作为个体的一种匮乏状态,它能引起个体的信息寻求活动,是信息寻求行为的驱动力。通过调查中小学教师,从信息需求产生的原因、目的、类型三个维度,对不同信息交互风格教师的信息需求进行了深入系统的研究。研究发现,不同信息交互风格教师的信息需求不同,有其各自的特点。 相似文献

在应对金融危机与经济衰退的过程中,G20从“财政部长及中央银行行长会议”升级为首脑峰会,在匹兹堡峰会上迈出了机制化的第一步。G20机制化原因,从国际体系层面看,是由于国际关系行为体之间相互依赖加强造成的决策不自主;从国际格局视角看,起因于世界政治多极化进程深入发展;从国际秩序角度看,是世界进入多元文明国家竞争与合作的时代的结果。在当前全球治理机制改革步履维艰之时,中国应积极推动G20机制化不断完善。 相似文献

BackgroundMaternal childhood experiences of maltreatment affect parenting and have consequences for a child’s social-emotional development. Adolescent mothers have a higher frequency of a history of maltreatment than adult mothers. However few studies have analyzed the interactions between adolescent mothers with a history of childhood maltreatment and their infants.ObjectiveThe aim of the study was to examine the effect of maternal childhood experiences of maltreatment on mother-infant emotion regulation at infant 3 months, considering both infant and mother individual emotion regulation and their mutual regulation.ParticipantsParticipants were 63 adolescent and young adult mother-infant dyads recruited at a hospital.MethodsThe mothers were administered the Adult Attachment Interview to evaluate reflective functioning and attachment and the Childhood Experiences of Care and Abuse was used to evaluate maternal childhood experiences of maltreatment. Mother-infant interactions were coded with a modified version of the Infant Caregiver Engagement Phases.ResultsDyads with mothers with childhood maltreatment (vs dyads with mothers with no maltreatment) spent more time in negative emotional mutual regulation (p = .009) and less time in positive and neutral mutual emotion regulation (p = .019). Cumulative maternal childhood experiences of maltreatment were associated positively with mother and infant negative states at individual and dyadic level and with the AAI scales of Passivity and Unresolved Trauma (p < .05). The effect of cumulative maternal childhood experiences of maltreatment on mother-infant emotion regulation was direct and not mediated by maternal attachment and reflective function.ConclusionsMaternal childhood experiences of maltreatment increase the risk connected to early motherhood, affecting mother-infant emotion regulation. 相似文献

Motivation predicts academic achievement beyond cognitive ability. Expectancy value theory (Eccles et al., 1983) is a widely accepted and powerful approach explaining academic achievement as well as educational choices and attainment. Recently, attention to the multiplicative term of expectancy and value beliefs has increased. Trautwein et al. (2012) reported a detrimental effect of high task value when expectancy beliefs were low. We aimed to replicate and extend their study by using a large, representative sample of students attending upper secondary school in the German federal state Schleswig-Holstein (N = 3367). Following Trautwein et al. (2012), we applied latent interaction modelling to test whether the predictive value of expectancy value interactions differs for grades, final examinations, and standardized test scores as measures of achievement in two domains. We took the multi-dimensional structure of task value into consideration, analyzing the four components (attainment, intrinsic value, utility and cost) separately. Both a verbal and a non-verbal domain (English as a foreign language and mathematics) were investigated. Overall, the results supported those of Trautwein et al. (2012). However, our findings suggested measure- and domain-specific differences when using expectancy value beliefs and their interactions to predict academic achievement. Interaction terms predicted final examination results in both English and mathematics. Further, interaction effects were significant for grades in English but not mathematics. In general, effect sizes of multiplicative terms were small, especially in contrast to expectancy beliefs. Findings are discussed regarding the practical and conceptual importance of the multiplicative term in expectancy value theory applied in an educational setting. 相似文献

In this opinion paper, I argue that the Covid-19 pandemic, as tragic and disastrous as it undoubtedly is, has also given us a rare opportunity to deeply examine the research and practice of information management in particular and information systems in general. To cope with the pandemic, we have retreated to the digital world and drastically changed the way we work. Yet these very practices can well shape the way we work in the post-pandemic world. Moreover, the pandemic is also a sharp lens through which we can study deep-rooted theoretical issues that otherwise would not have surfaced, or at least remained in the background. My call to the research community is to seize this rare opportunity. 相似文献
