Wikipedia is a widely used online reference work which cites hundreds of thousands of scientific articles across its entries. The quality of these citations has not been previously measured, and such measurements have a bearing on the reliability and quality of the scientific portions of this reference work. Using a novel technique, a massive database of qualitatively described citations, and machine learning algorithms, we analyzed 1 923 575 Wikipedia articles which cited a total of 824 298 scientific articles in our database and found that most scientific articles cited by Wikipedia articles are uncited or untested by subsequent studies, and the remainder show a wide variability in contradicting or supporting evidence. Additionally, we analyzed 51 804 643 scientific articles from journals indexed in the Web of Science and found that similarly most were uncited or untested by subsequent studies, while the remainder show a wide variability in contradicting or supporting evidence.

Students frequently request concept-list study guides prior to exams, but the benefits of instructors providing such resources are unclear. Research on memory and comprehension has suggested that some challenges in learning are associated with benefits to performance. In the context of an introductory psychology course, a study was conducted to investigate the impact of providing a concept-list study guide on exam performance, as opposed to having students create a study guide. Additionally, student preferences for various types of study guides were examined. Results indicated that although students greatly prefer that the instructors provide a study guide (as opposed to making their own), providing a concept-list study guide resulted in poorer exam performance. These results call for future research on the influence of study guides on student performance. [ABSTRACT FROM AUTHOR]

Key points: While the importance of citation context has long been recognized, simple citation counts remain as a crude measure of importance.Providing citation context should support the publication of careful science instead of headline‐grabbing and salami‐sliced non‐replicable studies.Machine learning has enabled the extraction of citation context for the first time, and made the classification of citation types at scale possible.

Social support is the subject of much research, but comparatively little attention has been paid to support seeking. Moreover, what research exists on support seeking has primarily addressed in-person support seeking, despite the proliferation of new support venues (e.g., Facebook, websites, etc.). This article uses a daily diary methodology to examine the support-seeking behavior men ( N = 41) and women ( N = 97) exhibit in response to various types of stressors. Results indicate that (a) in-person support seeking remains the most popular form; (b) compared to achievement stressors, social stressors are more likely to result in emotional support seeking rather than instrumental support seeking; and (c) men may engage in more support seeking than has been previously suggested by the literature, particularly in electronic venues.

As participant recruitment and data collection over the Internet have become more common, numerous observers have expressed concern regarding the validity of research conducted in this fashion. One growing method of conducting research over the Internet involves recruiting participants and administering questionnaires over Facebook, the world’s largest social networking service. If Facebook is to be considered a viable platform for social research, it is necessary to demonstrate that Facebook users are sufficiently heterogeneous and that research conducted through Facebook is likely to produce results that can be generalized to a larger population. The present study examines these questions by comparing demographic and personality data collected over Facebook with data collected through a standalone website, and data collected from college undergraduates at two universities. Results indicate that statistically significant differences exist between Facebook data and the comparison data-sets, but since 80% of analyses exhibited partialη2 < .05, such differences are small or practically nonsignificant in magnitude. We conclude that Facebook is a viable research platform, and that recruiting Facebook users for research purposes is a promising avenue that offers numerous advantages over traditional samples.

The article presents the study that explores on the use of haematopoietic stem cell transplantation (SCT) in the treatment of Fanconi anemia (FA) patients in Canada and the U.S. The topics discussed include the attributes of FA, the factors that influenced the decision making of FA patients and family members on SCT, and the benefits and probable risks of SCT.
