Identifying emotional expressions during family science engagement at home—a case study from a parent's perspective
No full textFamilies play a pivotal role in fostering children's science literacy, interests, and identities through everyday interactions and informal learning contexts, with parents as main facilitators. An essential, yet often underexplored, aspect of this process is the role of emotions in shaping science learning experiences. Emotions serve as powerful mediators of engagement, influencing key learning outcomes such as interest, motivation, achievement, and persistence. Despite the recognized importance of family engagement in science learning and the emotional dimensions associated with it, there is a significant gap in research specifically examining how families engage with science at home and the role emotions play in these settings. In this case study, we employed a mixed methods approach consisting of electro-dermal activity (physiological) and recorded observations (behavioral) to identify the emotional expressions of a mother as she engaged in five science activities with her children (ages 13, 11, 7, and 4) at home. All five activities were analyzed utilizing the following procedures: 1. Peak analysis, 2. Structural breaks, and 3. Microanalysis. We complemented our interpretation of the data with reflective notes and a reflective interview (self-reports) with the participant. The study reveals that mediated activities elicit more positive emotional expressions; the interrelationship between emotions and cognitive, social, and cultural domains needs to be accounted for while analyzing emotions, and highlights the methodological challenges of measuring emotions. By focusing on how a parent guides home science activities, it fills critical gaps in understanding family-based science engagement and sheds light on the affective dimensions of informal science learning. Employing a mixed methods approach provides a comprehensive understanding of emotional expressions during home science activities, which enhances the validity of the findings and captures the dynamic nature of emotions, offering a robust approach for analyzing the interplay between physiological, behavioral, and interpretive emotional expressions in real-world contexts

Pathways of interest and participation: How STEM‐interested youth navigate a learning ecosystem
No full textDespite considerable efforts in recent years to encourage Science, Technology, Engineering and Mathematics (STEM) interest and participation among youth, STEM interest during adolescence continues to decline. Recently, researchers, educators, and policymakers have used a learning ecology perspective to better understand the development and persistence of youth interest in STEM topics or activities. This study examined the dynamics of the STEM interest and participation pathways of three youth in an under-resourced, urban community. These three cases offer insights into how youth with a strong interest in a STEM topic or activity perceived the resources that were available to them in a STEM learning ecosystem and highlight the affordances and constraints each faced in pursuit of their interests. We interviewed each youth 4–5 times during their middle school and high school years (ages 11–14). The analysis reinforces the unique nature of youth interest pathways, but also common factors that contributed to each of these pathways. The ability of youth to navigate the ecosystem depended on the availability and accessibility of both in- and out-of-school learning resources related to their interest, and the support they received from significant adults in their lives in terms of both social, cultural, and financial capital. This study offers important insights into how STEM learning ecosystems might best be structured to enable more youth to develop strong, enduring interests in STEM

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
