Coding the Compromise: C, Rust, and the Developer's Trilemma : Safety, Performance, and Complexity Trade-offs in Stack Overflow Discussions
No full textThis study investigates how developers navigate the inherent trade-offs between safety, performance, and complexity in systems programming languages, specifically comparing C and Rust communities through their discussions on Stack Overflow. Using a mixed methods approach combining Latent Dirichlet Allocation (LDA) for computational topic modeling with Grounded Theory for qualitative analysis, 431 C posts and 573 Rust posts dating from 2015 to 2025 were examined. The research identifies fundamentally different orientations toward trade-offs between the two communities. C developers approach optimization from a performance-first perspective, actively constructing safety boundaries within performance constraints, guided by hardware-centric mental models. In contrast, Rust developers begin from a safety-first position, selectively relaxing safety guarantees when performance requires it, guided by ownership-aware abstractions. An integrated theoretical model called the Orientation-Shifted Triangle is presented, illustrating how language design fundamentally shapes developer reasoning processes and trade-off navigation strategies. Despite these contrasting orientations, both communities demonstrate a strong emphasis on empirical validation of optimization decisions. These findings have significant implications for language designers, development teams managing cross-language projects, and developer education programs. The research contributes to the understanding of how programming language design influences not just what developers can do, but how they think about and conceptualize engineering trade-offs in systems programming

Age-graded Variation in Japanese Visual Language : The different morphology of adults’ and children’s manga
No full textPrevious studies have shown that not only is there something called visual language through which we understand graphical expressions, but also that each culture has its own visual language. Furthermore, there are variances within these visual languages, denoted by genre, which can be interpreted to be dialects. In a similar fashion to a study by Neil Cohn and Sean Ehly in 2016, which uncovered the dialectical differences, this study has utilized 67 graphical schemas, known as visual morphemes, and a corpus of 20 volumes of Japanese comics, to investigate age-grading in the Japanese visual language. The corpus, consisting of 10 volumes aimed towards adults and 10 volumes aimed towards children, was searched for graphical schemas, and their relative frequencies were analyzed with independent samples t-tests. The results show great similarities between the populations, supporting the findings of previous studies indicating that there is a shared visual language between genres. However, there were also great differences in how the visual morphemes were used, with many morphemes being used in statistically different proportions between the populations. Further age-grading was also found in the absolute frequency and the meanings of the morphemes which were used, with children’s visual language appearing to be much more expressive. These results imply that there is significant age-grading in the Japanese visual language and that it can be characterized in several ways, including absolute frequency, content, and proportional use
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
