AbstractData variety is one of the most important features of Big Data. Data variety is the result of aggregating data from multiple sources and uneven distribution of data. This feature of Big Data causes high variation in the consumption of processing resources such as CPU consumption. This issue has been overlooked in previous works. To overcome the mentioned problem, in the present work, we used Dynamic Voltage and Frequency Scaling (DVFS) to reduce the energy consumption of computation. To this goal, we consider two types of deadlines as our constraint. Before applying the DVFS technique to computer nodes, we estimate the processing time and the frequency needed to meet the deadline. In the evaluation phase, we have used a set of data sets and applications. The experimental results show that our proposed approach surpasses the other scenarios in processing real datasets. Based on the experimental results in this paper, DV-DVFS can achieve up to 15% improvement in energy consumption.

AbstractSince its first discovery in late 2019, coronavirus disease 2019 (COVID-19) has been a global burden associated with significant morbidity and mortality. COVID-19 has been correlated with the development of hypercoagulable state that predisposes the patients to a higher risk of thromboembolism. Current evidence suggests higher incidence of thrombosis, particularly venous thrombosis, among hospitalized COVID-19 patients, mostly with critical illness. On the other hand, there is currently no data regarding the incidence of vivid thrombosis in ambulatory patients with mild COVID-19 and the incidence of concomitant arterial and venous thrombosis in COVID-19 is extremely rare. Herein, we describe catastrophic outcomes of concomitant lower limb arterial and venous thrombosis in a patient with mild COVID-19. This report highlights the occurrence of concomitant arterial and venous thrombosis in ambulatory setting and that this phenomenon resulted in catastrophic clinical consequences.

The global burden of cancer is escalating as a result of dramatic increases in the use of tobacco in the developing world. The use of tobacco is linked to the development of a broad variety of cancers, mainly lung cancer, the single most common cancer in the world. Tobacco smoking-attributable deaths extends beyond cancer and include stroke, heart attack and COPD. Widening disparities in cancer-related mortality have shifted towards a more dramatic burden in the developing world. Appropriate interventions must be implemented to reduce tobacco use and prevent global mortality that has escalated to epidemic levels. Tobacco control policies, including public health advertisement campaigns, warning labels, adoption of smoke-free laws, comprehensive bans and tax policies are highly effective measures to control tobacco use. Clinicians and academic institutions have to be actively committed to support tobacco control initiatives. The reduction in cancer related morbidity and mortality should be viewed as a global crisis and definitive results will depend on a multilevel effort to effectively reduce the burden of cancer, particularly in underprivileged regions of the world.

The paper presents the results of a study of the opinion of fourth- and eighth-grade primary school students (N=880) on the characteristics of teachers? oral presentation. The main goal is to take into account students? opinion in the new didactic grounding of the monologue teaching method. This implies appreciation of the proven values of applying the monologue method in teaching and its adaptation to suit the needs of modern teaching, first of all, the needs of students. In this context, we think that the perception of the monologue method from students? perspective is very significant in assessing the limitations and the possibilities of its application incurrent conditions. Students described the characteristics of teachers? oral presentation that they liked best and least and provided suggestions on methods of enhancing the oral presentation of teachers. Students gave the most positive assessments to oral presentations that were clear from the linguistic, logical and the didactic and methodological aspects. On the other hand, the majority of students? negative comments were related to inadequate behavior of some teachers as speakers and to ?incomprehensible oral presentation?. The results show that students gave very clear and specific statements on the positive and negative characteristics of teachers? oral presentation, which, in the given didactic context, can be very indicative for the enhancement of this teaching element both for teachers and the didactic experts.

Compartmentalizing our distinct personal identities is increasingly difficult in big data reality. Pictures of the person we were on past vacations resurface in employers’ Google searches; LinkedIn which exhibits our income level is increasingly used as a dating web site. Whether on vacation, at work, or seeking romance, our digital selves stream together. One result is that a perennial ethical question about personal identity has spilled out of philosophy departments and into the real world. Ought we possess one, unified identity that coherently integrates the various aspects of our lives, or, incarnate deeply distinct selves suited to different occasions and contexts? At bottom, are we one, or many? The question is not only palpable today, but also urgent because if a decision is not made by us, the forces of big data and surveillance capitalism will make it for us by compelling unity. Speaking in favor of the big data tendency, Facebook’s Mark Zuckerberg promotes the ethics of an integrated identity, a single version of selfhood maintained across diverse contexts and human relationships. This essay goes in the other direction by sketching two ethical frameworks arranged to defend our compartmentalized identities, which amounts to promoting the dis-integration of our selves. One framework connects with natural law, the other with language, and both aim to create a sense of selfhood that breaks away from its own past, and from the unifying powers of big data technology.

Prolonged sitting has a detrimental effect on lipid metabolism and insulin sensitivity leading to increased risks of metabolic conditions. Attendees at conferences typically sit for long periods during oral presentations. The use of visual cues or ‘just-in-time’ prompts during oral presentations can inform audiences about the deleterious effects of prolonged sitting and encourage them to avoid sitting for long periods. It remains largely unclear whether these ‘just-prompts used in a conference setting are effective in reducing prolonged sitting. The ‘just-in-time’ prompts were used in two separate conference audiences- one focused on health and the other on language. Ten sessions were randomly assigned to the experimental group (EXPT, with the JIT prompt) and ten sessions to the control group (CON, without the JIT prompt). In both conferences, the proportion of the attendees who chose not to sit during the oral presentations in the EXPT conditions was less than 10%. The main finding was that the use of the JIT prompt to discourage sitting at the health conference where attendees were likely to be knowledgeable about the dangers of prolonged sitting was ineffective (EXPT vs CON conditions, p>0.05; ES=0.69) compared to conference attendees at a language conference (EXPT vs CON conditions, p<0.05, ES=1.14).

Over the last few years, data studies within Social Sciences watched a growth in the number of researches highlighting the need for more proficuous participation from the Global South in the debates of the field. The lack of Southern voices in the academic scholarship on the one hand, and of recognition of the importance and autonomy of its local data practices, such as those from indigenous data movements, on the other, had been decisive in establishing a Big Data in the South agenda. This paper displays an analytical mapping of 131 articles published from 2014-2016 in Big Data & Society (BD&S), a leading journal acknowledged for its pioneering promotion of Big Data research among social scientists. Its goal is to provide an overview of the way data practices are approached in BD&S papers concerning its geopolitical instance. It argues that there is a tendency to generalise data practices overlooking the specific consequences of Big Data in Southern contexts because of an almost exclusive presence of Euroamerican perspectives in the journal. This paper argues that this happens as a result of an epistemological asymmetry that pervades Social Sciences.

With the development of technology and the dominance of the digital world, typography has become a critical issue. Information design systems are considered as one of the significant areas of graphic design and big data provides essential information on data visualization. This research aims to analyse the effects of typographic elements on visualizing data in terms of visual communication, by discussing the value that typography gives to design space. The research discusses randomly selected 10 infographic design samples published in the last six months on google. From the results, 5 designs with typographic concern were more favourable and visually more striking and preferable than the other 5 designs in terms of design disciplines. As in all areas of graphic design, it is argued that the power of typography is an indisputable concept in data visualization, which is seen as a sub-branch of information design.
