A secure and privacy preserved infrastructure for VANETs based on federated learning with local differential privacy
No full textAdvancements in Vehicular ad-hoc Network (VANET) technology have led to a growing network
of interconnected devices, including edge devices, resulting in substantial data generation. The
data generated by vehicles is subsequently shared with other devices, such as Roadside Units
(RSUs). However, ensuring secure data sharing poses a significant challenge due to the potential
risk of data breaches. Recently, Federated Learning (FL) has garnered substantial attention in the
research community, enabling data owners to collaboratively learn a shared prediction model
while retaining all their training data privately. However, traditional FL-based approaches are
susceptible to inference and gradient leakage attacks. This paper presents a framework for private
data sharing in VANETs using FL with local differential privacy. In the first layer, vehicles apply
local differential privacy techniques to their data before sharing it with the RSU. The second
layer is responsible for training model parameters at the RSU and updating the trained weights
with the training server. To assess our system’s performance, we evaluate it based on accuracy
and simulation time for both local and global parameter sharing. Additionally, we measure each
client’s performance by calculating accuracy measures during each iteration. The experimental
results demonstrate that our framework not only ensures security against inference and gradient
leakage attacks but also exhibits superior efficiency compared to its counterparts
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
The Relation Between Interpersonal Relationship Satisfaction and Spiritual Well-Being in Adults
No full textThe purpose of the study is a correlational analysis between interpersonal relationship satisfaction and spiritual well-being in adults. This study is a quantitative, correlational study. Data were collected through purposive sampling technique from different institutes and organizations. The sample size of the study was sample (n = 200). The age ranges of participants were 20–35 years. Two scales, Spirituality Index of Well-Being (SIWB) and Relationship Assessment Scale (RAS-G), were used for data collection and the data was analyzed statistically. The analysis was carried out by the statistical tests correlation test, t-test and ANOVA. It was revealed through this study that interpersonal relationship satisfaction and Spiritual well-being were positively correlated with each other. Additionally, it was found that married adults have strong spiritual well-being and interpersonal relationships than unmarried adults. However, there was no gender significance difference was found. Moreover, it was revealed that the spiritual well-being and interpersonal relation strength is higher in upper ages then in lower ages

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
