Evidence of open access of scientific publications in Google Scholar: A large-scale analysis

This article uses Google Scholar (GS) as a source of data to analyse Open Access (OA) levels across all countries and fields of research. All articles and reviews with a DOI and published in 2009 or 2014 and covered by the three main citation indexes in the Web of Science (2,269,022 documents) were selected for study. The links to freely available versions of these documents displayed in GS were collected. To differentiate between more reliable (sustainable and legal) forms of access and less reliable ones, the data extracted from GS was combined with information available in DOAJ, CrossRef, OpenDOAR, and ROAR. This allowed us to distinguish the percentage of documents in our sample that are made OA by the publisher (23.1%, including Gold, Hybrid, Delayed, and Bronze OA) from those available as Green OA (17.6%), and those available from other sources (40.6%, mainly due to ResearchGate). The data shows an overall free availability of 54.6%, with important differences at the country and subject category levels. The data extracted from GS yielded very similar results to those found by other studies that analysed similar samples of documents, but employed different methods to find evidence of OA, thus suggesting a relative consistency among methods.     

Author-level metrics in the new academic profile platforms: The online behaviour of the Bibliometrics community

The new web-based academic communication platforms do not only enable researchers to better advertise their academic outputs, making them more visible than ever before, but they also provide a wide supply of metrics to help authors better understand the impact their work is making. This study has three objectives: a) to analyse the uptake of some of the most popular platforms (Google Scholar Citations, ResearcherID, ResearchGate, Mendeley and Twitter) by a specific scientific community (bibliometrics, scientometrics, informetrics, webometrics, and altmetrics); b) to compare the metrics available from each platform; and c) to determine the meaning of all these new metrics. To do this, the data available in these platforms about a sample of 811 authors (researchers in bibliometrics for whom a public profile Google Scholar Citations was found) were extracted. A total of 31 metrics were analysed. The results show that a high number of the analysed researchers only had a profile in Google Scholar Citations (159), or only in Google Scholar Citations and ResearchGate (142). Lastly, we find two kinds of metrics of online impact. First, metrics related to connectivity (followers), and second, all metrics associated to academic impact. This second group can further be divided into usage metrics (reads, views), and citation metrics. The results suggest that Google Scholar Citations is the source that provides more comprehensive citation-related data, whereas Twitter stands out in connectivity-related metrics.     

The family check-up with high-risk indigent families: preventing problem behavior by increasing parents' positive behavior support in early childhood

Seven hundred thirty-one income-eligible families in 3 geographical regions who were enrolled in a national food supplement program were screened and randomized to a brief family intervention. At child ages 2 and 3, the intervention group caregivers were offered the Family Check-Up and linked parenting support services. Latent growth models on caregiver reports at child ages 2, 3, and 4 revealed decreased behavior problems when compared with the control group. Intervention effects occurred predominantly among families reporting high levels of problem behavior at child age 2. Families in the intervention condition improved on direct observation measures of caregivers' positive behavior support at child ages 2 and 3; improvements in positive behavior support mediated improvements in children's early problem behavior.     

Performance Versus Objective Testing and Gender: An Exploratory Study of an Advanced Placement History Examination

To explore a phenomenon of gender differences in Advanced Placement examinations, random samples of free-response test booklets were taken from the 1986 examination in U.S. History. These examinations were chosen because they consistently show significant gender differences in objective scores but no gender differences in free-response scores. A rescoring of the free responses was conducted that focused on their historical content. This rescoring was conducted by readers other than those who conducted the original scoring and involved tallies of specific historical points made, supporting evidence given, and factual errors. Ratings were also made of handwriting quality, neatness, and English composition quality of the free responses. Analyses conducted indicate that free-response tasks of the type examined may have inherent characteristics that reward English composition abilities, and that some females may compensate for inferior historical knowledge with superior English composition abilities.     

Sympathy for the Devil

Since Melvin Burgess published his first childrens book, The Cry of the Wolf (1989) he has had the reputation of being a powerful and challenging writer, discussing issues that many other writers have shunned. But it was with Junk (Smack in the US) in 1996 that he became a notorious media figure. This Carnegie winning novel showed teenagers not only taking drugs, but enjoying them, and sex, too! As a whole, though, this book also showed the dangers of hard drugs, and did anything but glamorise addiction. The book was also innovative in using multiple narrative voices, so that moral certainties are continually being challenged, shown to be but partial. Burgess continued this technique in Bloodtide (1999), which is undoubtedly his most powerful book yet (a second volume is on its way), updating the Icelandic Volsunga saga in a bleak, futuristic London. Lady: My Life as a Bitch (2001) and Doing it (2003) also brought much media attention, both dealing explicitly with teenage sex. These are the main books that Burgess talks about in his article. However, his range is far wider, and his other texts should not be forgotten: he has written several novels for younger readers, a picture book, The Birdman (2000) and an excellent novelisation of the film Billy Elliot (2001). His ability to write gripping, absorbing stories with memorable characters is always foremost, whatever other issues might be addressed.     

I'm Happy with My Mommy: Low-Income Preschoolers' Causal Attributions for Emotions

This study examined low-income African American and European American preschoolers' socioemotional causal attributions. Forty-seven Young (M = 48 months) and Old (M = 62 months) preschoolers were asked to justify a puppet's current emotion and to talk about their past emotional experiences. Responses were coded for Causal Theme and Clarity. Old preschoolers were twice as likely to attribute interpersonal themes, and Young preschoolers were 4 times more likely to generate causal themes that were uncodeable. In terms of clarity, children provided clearer responses for anger and fear than they did for happiness. Old preschoolers' explanations for emotions were clearer than young preschoolers' and young African Americans', who had the most difficulty explaining emotions. Results indicate that younger preschoolers, particularly young African Americans, may need help articulating emotions. Suggestions for how adults can scaffold preschoolers' emotional reasoning are discussed.

To click or not to click: investigating conflict detection and sourcing in a multiple document hypertext environment

This study investigated whether accessing conflicting claims in other documents by means of hyperlinks embedded within currently read documents may facilitate conflict detection and source-content integration. Norwegian undergraduates (n?=?85) read multiple conflicting documents on a controversial health-related issue, with half of the conflicting claims across documents hyperlinked and the other half not. Moreover, half of the participants were told that they would get more information by clicking on the links (weak prompting condition) while the other half were additionally told that clicking on the links was necessary to get a more complete understanding of the issue (strong prompting condition). Results indicated that the extent to which participants accessed conflicting claims in other documents via the hyperlinks was positively related to their detection of cross-document conflicts as well as their integration of source-content information. A mediational analysis indicated that conflict detection mediated the effect of accessing conflicting claims via the hyperlinks on source-content integration. No relationship was found between the prompting condition and participants’ selection of the hyperlinks. The theoretical significance as well as the practical value of our findings are discussed.
