This paper deals with the reconfigurations of Noelle-Neumann's (2010) original theory and presents an analysis categorization for the contemporary spiral of silence, which involves four mechanisms: 1) accumulation; 2) consonance; 3) ubiquity; and 4) anonymity. In order to avoid excluding the term social and analyzing meanings and technologies separately, the results in this paper were presented from a sociocultural matrix reception study with eight unionized teachers and eight neo-Pentecostal evangelicals residing in the city of Curitiba (PR). Once determining that algorithms are relevant towards defining new cultural patterns of social interaction, we found the need to investigate consolidated theories in the field of communication and journalism in the light of algorithmic mediations.

This paper aims to show the opposition between the Humanist cultural tradition and the main theses currently defended by Posthumanism. The structure of the paper is built upon the corresponding answers provided by both trends to the three main philosophical questions: How do we know reality? What are the world and life, and how are they explained? What is the best way to live one’s life? Gnoseology (or theory of knowledge), Ontology, and Deontology or Ethics have respectively tried to provide answers for such questions. Certain ambiguities of the Posthumanist dehumanizing project are also addressed. The paper concludes with an exposition of the arguments that justify the continuity of Humanist values, principles, and rights, updated according to the demands of our time.

This paper sets forth an algorithm which can recognize any type of the Spanish voseo conjugations, based on a parametric analysis of its morphological typology. The algorithm is built as a sequence of a minimum of two and a maximum of five operations, or steps. Both the linear arrangement of the steps and the structure of the queries are based on an implicit theory of the relative markedness or complexity of each variant and the parametric analysis of the typology. Thus, assessing the speed and efficiency of the algorithm becomes an indirect measure of the underlying analysis. The algorithm also invites to speculate about how the variable data relates to the way it is acquired or learned. [ABSTRACT FROM AUTHOR]

In this research paper, we examine forms of work organization implemented in Mercado Libre based on interviews with its workers in Argentina. We analyze the historical course of human resources management until the incursion of the pandemic. As part of the findings, we can point out that the evolution of work management and well-being shows ruptures and continuities, where emotions become increasingly relevant in human resources policies. Inspired by positive psychology in the 90s, such policies focused on the resilient individual. This figure has become more relevant since COVID-19, when the management of intimacy and emotions is mediated by the use of technologies supported by big data. [ABSTRACT FROM AUTHOR]

This paper discusses the challenges encountered by counter-hegemonic social movements and activists working on digital platforms such as Facebook and Twitter, used as tools for mobilizing and disseminating information. To achieve this goal we describe how digital platforms colonize lifeworld by collecting data based on user interactions and how it affects activists who build solidarity networks. We then discuss the performance of counter-hegemonic movements and their opponents and present the concept of coded activism. To conclude our argument, we present proposals for the action of social movements in an Internet dominated by monopolistic corporations. [ABSTRACT FROM AUTHOR]

Risk analyses applied to radiotherapy treatments have become an undeniable necessity, considering the dangers generated by the combination of using powerful radiation fields on patients and the occurrence of human errors and equipment failures during these treatments. The technique par excellence to execute these analyses has been the risk matrix. This paper presents the development of a new algorithm to execute the task with wide graphic and analytic potentialities, thus transforming it into a very useful option for risk monitoring and the optimization of quality assurance. The system SECURE-MR, which is the basic software of this algorithm, has been successfully used in risk analysis regarding different kinds of radiotherapies. Compared to previous methods, It offers new possibilities of analysis considering risk controlling factors as the robustness of reducers of initiators frequency and its consequences. Their analytic capacities and graphs allow novel developments to classify risk contributing factors, to represent information processes as well as accidental sequences. The paper shows the application of the proposed system to a generic process of radiotherapy treatment using a lineal accelerator. [ABSTRACT FROM AUTHOR]

This paper presents an overview about control methods implemented on robotic convoy systems or cooperative systems on mobile platforms which can be used for path planning, orientation, environment perception, route tracking and control systems in which involve the measurement, analysis and interpretation of different variables for further implementation. A review was made of investigation articles on bibliographic indexes and databases about control methods used in convoy systems to evidence progress, trends and application methods.
