Gaps in affiliation indexing in Scopus and PubMed

Objective

The authors sought to determine whether unexpected gaps existed in Scopus''s author affiliation indexing of publications written by the University of Nebraska Medical Center or Nebraska Medicine (UNMC/NM) authors during 2014.

Methods

First, we compared Scopus affiliation identifier search results to PubMed affiliation keyword search results. Then, we searched Scopus using affiliation keywords (UNMC, etc.) and compared the results to PubMed affiliation keyword and Scopus affiliation identifier searches.

Results

We found that Scopus''s records for approximately 7% of UNMC/NM authors'' publications lacked appropriate UNMC/NM author affiliation identifiers, and many journals'' publishers were supplying incomplete author affiliation information to PubMed.

Conclusions

Institutions relying on Scopus to track their impact should determine whether Scopus''s affiliation identifiers will, in fact, identify all articles published by their authors and investigators.

Differential thermal expansion as a cause of salt decay: literature review,experiments, and modelling of micro and macro effects on Ançã limestone

Salt decay is one of the harshest, most frequent, and more complex types of decay of porous materials in built heritage, including natural stones, ceramics, and mortars. In this article, we address the mechanism of thermal expansion, which is one of the least studied, yet most controversial, of those proposed over time to explain salt decay. We present a review of scientific literature on the topic, followed by a study of the effects of thermal expansion on a specific material, the well-known Ançã limestone. The study included experimental measurement of the linear thermal expansion coefficient of the Ançã, both in its natural state and with varying contents of sodium chloride, sodium sulphate, or sodium nitrate. The results show that this coefficient: (i) is significantly higher when the stone is contaminated with salt; and (ii) scales approximately with the amount of salt contained in the stone pores, regardless of the type of salt. Based on these results and on modelling of damage modes at the microscopic and macroscopic levels, respectively, we conclude that thermal expansion can cause powdering, disaggregation, or other types of decay consisting of internal loss of cohesion. However, it is not likely to cause exfoliation of salt-loaded layers.     

Feeding a growing team: action learning as fertiliser

Here I describe an action learning programme I ran for a youth offending team, with 15 of the 19 team members, over a six month period. The programme emerged from running a development session for the team, which highlighted a need for more ownership of the work of the team by workers and for them to be involved in setting the direction of the team's work. Most members felt they had benefited from the programme, in pushing them into new roles and taking on more responsibility in the team. I believe that action learning acts as a powerful fertiliser on seeds of growth, providing a rich, multi-faceted and powerful ingredient for cultivation.     

The art of questioning in online learning environments: the potentialities of feedback in writing

Research on feedback has focused more on generating feedback rather than on how students use it and implement it; that is, what type of cognitive, metacognitive or affective activity students engage in once they have received feedback. In order to visualize feedback use and implementation, a quasi-experimental study was carried out. Students were randomly assigned to four conditions, in respect of the type of feedback (corrective, epistemic-questioning, suggestive and epistemic?+?suggestive). This research provides evidence of how students use and implement feedback in online collaborative writing. Findings show that when students received epistemic?+?suggestive feedback, they engaged in more cognitive and metacognitive activities. With regard to implementation, students who received epistemic?+?suggestive feedback obtained better final marks. This study highlights the importance of metacognitive activities in online learning, as they play a key role in the implementation of feedback.     

A probabilistic approach to student workload: empirical distributions and ECTS

The ECTS, European Credit Transfer System, is now widely used throughout higher education institutions as it facilitates student mobility within Europe and the comparison of study programs and courses. Most European institutions provide students with the number of ECTS each course and module is worth. A full-time student needs to complete 60 ECTS per academic year, which represents about 1500 to 1800 h of study. However, there is a lack of research showing that ECTS metrics have been properly implemented in different degrees and universities. The aim of this paper is to assess the relevance of the ECTS metric as a valid indicator of students’ and courses’ workloads. Detailed workload measurements have been taken in two Spanish universities, with 250,000 work hours monitored from 1400 students. This is the first study published with such a large dataset that includes a range of simultaneous courses and throughout a whole semester. Empirical distribution functions of workload indicators have been obtained. Evidence is provided indicating that nominal ECTS credit hours may be overestimated, that the variability of student workload could be too large for ECTS to sensibly characterize course workload, and that workload statistics of courses with same nominal ECTS are generally not comparable. Although the ECTS metric conception seems to be a valid metric to facilitate mobility between different institutions and higher education systems, in practice, according to this study, it requires revision, at least in the two institutions that have been included in this study. Further studies like the present one are required to test if this is a broader problem that has implications for the comparability of degrees across Europe.     

Facilitating the Development of Assessment Literacy

When STARS reform efforts were launched in 2000, teacher training in assessment was seen as crucial to the success of the program. The STARS reform efforts focus on both supporting the implementation of quality classroom assessment practices and implementing a district-based accountability system. The training programs described in this article were developed in response to one or both of these needs. Two of the programs were designed to provide training to experienced teacher. The other two programs were designed to meet the needs of pre-service teachers. Evidence suggests that the training programs have had a positive impact on teacher confidence, knowledge, and skill in key areas of assessment. In addition, there also appears to be evidence, while somewhat limited, which suggests students also experience positive outcomes.     

Handwriting fluency and visuospatial generativity at primary school

Handwriting is a complex activity that involves continuous interaction between lowerlevel perceptual-motor and higher-level cognitive processes. All handwriting models describe involvement of executive functions (EF) in handwriting development. Particular EF domains associated with handwriting include maintenance of information in working memory, inhibition of prepotent responses, and shifting and sustaining of attention. Generativity, an EF domain that has not been extensively studied, may play a role in the acquisition and automation of handwriting. We hypothesized that neuropsychological performances and handwriting fluency would be mutually associated, and that visuospatial generativity could have a specific role in handwriting speed. We enrolled 96 children who completed a comprehensive neuropsychological battery. The study found that handwriting speed was associated with visuospatial fluency, which involves behavioural execution and initiation. In learning and performing handwriting, there is an inherent non-exclusive role of fine motor skills.     

Developing Symbolic Interpretation Through Literary Argumentation

Literature can be a powerful resource for adolescents’ psychosocial development, as it provides opportunities to experience the world through the perspectives of others and juxtapose these with one’s own experiences. However, gaining access to these perspectives requires going beyond literal words on the page to explore interpretive meanings. This mixed-methods case study addresses the need to better understand how adolescent students learn to interpret literary works. Specifically, 9th-grade students participated in a 5-week instructional module focused on symbolic interpretation and coming of age themes in texts with a variety of sources of complexity. The primary data sources were an intentional sample of classroom discussions and essays written before and after instruction. Analyses indicate that students learned to make interpretive claims around symbolism. Textual evidence to support these claims was evident in whole-class discussions but less so in the written essays. Students also struggled to reason about why evidence supported particular claims and how the interpretive claims were related to understanding the characters and their worlds. Discussion focuses on the value of symbolic interpretation as a starting point for engaging adolescents in interpretive practices but notes that developing facility with literary interpretation takes concerted effort over longer periods of time.
