Key points
- New forms of human/machine dialogue are emerging as robots understand vast amounts of content rather than simply indexing content as strings of characters.
- Recognizing strings of characters as entities (e.g. = names = authors) allows for meaningful associations between entities and reasoning over these relationships.
- Web‐scale adoption of the Semantic Web approach has been slow because it is too complex to implement and does not scale.
- User intent, discovered through conversational models of human–computer interaction, allows for a deeper understanding of exactly what researchers are looking for.
- Personal agents hold the promise of finding information that we will find useful before we have started to look for it.
- Publishers can use Academic Knowledge APIs to interpret academic user queries and find rich information from the Microsoft Academic Graph.

This paper reports findings from a study of LookJed, the oldest and largest on-line forum for Computer Mediated Discussion
among individuals interested in Jewish education. The study adopted a “cyber-ethnographic” approach, with postings to the
forum seen as “acts of communication” that reveal what is important to their authors. An interest in exploring similarities
between forum conversations and those in teachers’ lounges led to an investigation of Herring’s claim that most listservs
do not include discussion at all, only the trading of information. This investigation found that active forum participants
generally use the forum for discrete purposes, most commonly to exchange information about “subject matter” or “teaching material”,
less commonly to exchange opinions and ideas, and rarely to do both. Integrating an analysis of patterns of contribution with
an examination of their discursive content reveals six preeminent “types” among the population of contributors, each of whom
participates in the forum in different ways and acts with different purposes. Although this typology is at best suggestive
and needs to be tested against other listserv cases, its easy identification suggests that in order to better understand the
cultures of virtual forums, it is important to pursue a more variegated characterization of listserv participants and their
motivations than has typically been the case in CMD research where users are most frequently identified as either lurkers
or fanatics, or as active or passive participants. 相似文献

In the present study, we tested the assumption that performance in a knowledge retrieval test would be lower in secondary school students with temporarily depleted self-control strength (n = 53) compared to secondary school students with temporarily available self-control strength (n = 56). After manipulating self-control strength, students were instructed to memorise the names and the functions of the human eye and to recall as many names and functions as possible following a one-min distraction task. The results supported our assumptions, as students with depleted self-control strength performed significantly worse in the knowledge retrieval task compared to students whose self-control strength had not been temporarily depleted. The results suggest that depleted self-control strength may negatively affect academic performance and hinder a successful academic career. The theoretical and practical implications of these findings are discussed. 相似文献

This investigation tested the psychometric properties of the Attitudes Toward Seeking Professional Psychological Help Scale-Short
Form (ATSPPH-SF; Fisher and Farina [Journal of College Student Development, 36, 368–373, 1995]) in a sample of 338 Mainland Chinese college students. Using back-translation, the ATSPPH-SF was translated into simplified
Chinese. Confirmatory factor analysis did not support the original one-factor model. Subsequently, exploratory factor analysis
suggested a 7-item, two-factor model; however, the new factor structure yielded poor reliability coefficients, below .60.
Results suggest that the help-seeking construct as operationalized by the ATSPPH-SF may not be valid for the Chinese population.
The importance of designing indigenous instruments for help-seeking attitudes is discussed. 相似文献

This study explored the relationships between student background and academic performance in college introductory environmental science (ES) courses at a large U.S. research university with the premise that this analysis may inform teaching practices, curricula, and efforts to increase retention. We surveyed over 700 students across eleven introductory ES courses and used multiple linear mixed-effects regressions to model the data. We found that students who grew up in rural settings or who had frequent childhood interactions with natural environments earned higher grades, on average, than students from urban settings or with fewer childhood interactions with natural environments. Our results indicate that students reporting frequent childhood interactions with forests, for example, were projected to earn grades up to 1.5 letter grades higher in these courses than students with no such interactions. In addition, students with frequent childhood interactions with nature were likelier to report that such interactions helped them in their ES course, suggesting that these students may recognize the value of these experiences. Greater interest in the subject matter also correlated with higher ES course grades, whereas amount of prior ES coursework did not. We discuss the possible implications of these correlations for ES academic performance and educational practice. 相似文献
