This paper summarizes three lines of research that are motivated by the practical problem of helping users find information from external data sources, most notably computers. The application areas include information retrieval, text categorization, and question answering. A common theme in these applications is that practical information access problems can be solved by analyzing the statistical properties of words in large volumes of real world texts. The same statistical properties constrain human performance, thus we believe that solutions to practical information access problems can shed light on human knowledge representation and reasoning. 相似文献

论文对古代典籍所载"易象"一名作了新的解读。认为所谓"易象",仅是当时《周易》的另一种称谓而已,它并不神秘;"易象"与今本《象传》没有直接联系,尚无渊源,《象传》"演德","易象""尊礼尚施",至汉代仍保存有以古礼诠释《周易》的传统;古代《周易》原有《象经》,或以《卦下易经》当之,惜已不传;但在清人的《易》著中,至今仍可见其传承的轨迹。 相似文献

This study examined the effects of text messaging class arrival to an academic counselor on the attendance and punctuality of 4 college student athletes. Each participant had a history of class tardiness and was considered to be at risk for academic failure. Class attendance and punctuality improved for all participants. 相似文献

Introduction and objective
An experiment was conducted in a school context to examine whether joy and pride, two positive emotions, can promote children's acquisition of knowledge in a reading comprehension situation.Method
The experiment consisted of inducing either a positive emotion (i.e., joy, pride) or a neutral state to 10-year-old children using an autobiographical recall task. Once the induced state was evaluated, children were submitted to a reading/comprehension task of a neutral text. When they finished reading this text, a questionnaire was used to assess not only their memory of the information provided in the text, but also their ability to make inferences.Results
Our main results highlighted a positive effect of joy on children's inference making.Conclusion
This study confirmed the relevance of taking into account the emotional state of children engaged in knowledge acquisition situations at school. 相似文献7.

To inform ethical procedures for human subjects research using mobile health (mHealth), we examined perceived risks and benefits of study participation among emerging adults (N = 54) with drug use who completed text message assessments of substance use and sexual behaviors. Most participants reported comfort with participation and some reported perceived benefits, such as improved relationships. Perceived risks were infrequently reported, including negative emotions and legal or financial concerns. In conclusion, participants from a vulnerable population reported few perceived harms of participation in longitudinal mHealth assessments of sensitive behaviors. Researchers should continue characterizing participants’ perspectives on ethical aspects of mHealth research. 相似文献

Cell phone use while driving (CPWD) has been shown to significantly reduce driver safety. This is a particular concern among young drivers who possess less driving experience and tend to engage in high rates of cell phone use. The present study identified psychological predictors of near accidents related to CPWD among a sample of 385 college student drivers. Participants answered a series of questions regarding their use of a cell phone while driving and completed measures of mindfulness, polychronicity, and intrusive thinking. Students who reported talking on their phone or texting more frequently while driving reported a higher incidence of near accidents related to each behavior. However, after controlling for CPWD, multiple regression analysis indicated that those who reported experiencing more cell phone-related intrusive thoughts also experienced more near accidents. Furthermore, two facets of mindfulness—acting with awareness and nonjudging of inner experience—were negatively associated with near accidents. These findings suggest that individuals who are more aware of the present moment and accepting of their affective responses may better regulate their attention while using a cell phone behind the wheel. 相似文献

AbstractOn 2 April 1535, Robert Singleton, chaplain to Queen Anne Boleyn, preached a sermon at Paul's Cross. The unique, surviving printed copy of the sermon is housed in the Wren Library of Lincoln Cathedral. From 1533, Singleton had been a member of the circle of avant-garde evangelicals gathered at the margins of the Tudor court under the patronage of Thomas Cromwell. His sermon at Paul's Cross contributed to an orchestrated campaign in support of Cromwell's legislative programme, then proceding through Parliament, to sever all links of ecclesiastical jurisdiction with Rome and to confirm Henry's headship of the Church of England. The sermon interprets Paul's allegory of the earthly and the heavenly Jerusalem in the Epistle to the Galatians as a model for thinking about the distinction between the invisible and visible Church. Singleton harnesses Pauline ecclesiology in an apology for the royal supremacy. Presented here is a transcribed copy of the original printed version. 相似文献

We compared the working memory requirements of two forms of mental addition: exact calculation (e.g., 63 + 49 = 112) and approximation (e.g., 63 + 49 is about 110). In two experiments, participants solved two-digit addition problems (e.g., 63 + 49) alone and in combination with a working memory task (i.e., remembering four consonants). In Experiment 1, participants chose an answer from two alternatives (e.g., exact: 112 vs. 122; approximate: 110 vs. 140). In Experiment 2, participants responded verbally with exact or approximate answers. In both experiments, the working memory load impaired exact and approximate addition performance, but exact addition was affected more. Load also impaired performance on problems with a carry operation in the units (e.g., 28 + 59 or 76 + 57) more than on problems without a unit carry (e.g., 24 + 53 or 76 + 52). These results identify the carry operation as the source of the working memory demands in multidigit addition. 相似文献
