Taxonomy of Security-related Issues in Android Apps : An Empirical Study
No full textSmart applications (apps) have become the primary means of obtaining digital services in many aspects of our daily lives, such as health care, e-banking, online shopping, etc. With the growing number of smart apps being created, the likelihood of security vulnerabilities has increased significantly. Smartphone developers remain vigilant about security concerns during their mobile app development, installation, and maintenance. This paper presents a large-scale empirical study examining critical security issues in open-source Android apps obtained from GitHub. We analyzed 111,224 commits across 2,187 apps and identified 689 commits explicitly related to security issues. Additionally, we utilized the card-sorting approach to construct a taxonomy/catalog of ten distinct categories of security-related issues. According to our findings, the most frequent security-related problem in our dataset was related to permission issues, accounting for 370 instances (53.7%), followed by Login, with 160 instances, representing 23.22%. On the other hand, Privacy and Framework issues were less frequent, with only 5 (0.72%) and 3 (0.43%) instances, respectively, in our dataset. Moreover, our taxonomy also included 71 sub-categories/sub-themes, with permission issues having the highest number of sub-categories (23) and Framework issues with the lowest numbers (2). Developers discussed permission sub-categories, such as camera permission, WiFi permissions, storage permission, WRITE/READ_PHONE_STATE permission, and location permission, among others, in their code commits. The insights gained from our study provide a foundation for comprehending the primary security concerns from the viewpoints of both researchers and software practitioners.nonPeerReviewe

No full textGoing 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
Strong convexity-guided hyper-parameter optimization for flatter losses
Get PDFWe propose a novel white-box approach to hyper-parameter optimization.
Motivated by recent work establishing a relationship between flat minima and
generalization, we first establish a relationship between the strong convexity
of the loss and its flatness. Based on this, we seek to find hyper-parameter
configurations that improve flatness by minimizing the strong convexity of the
loss. By using the structure of the underlying neural network, we derive
closed-form equations to approximate the strong convexity parameter, and
attempt to find hyper-parameters that minimize it in a randomized fashion.
Through experiments on 14 classification datasets, we show that our method
achieves strong performance at a fraction of the runtime.Comment: v
