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.

This paper presents an image synthesis algorithm for rendering views of a real scene taken with a virtual camera which is located between two real cameras. Specifically, this paper presents how, under certain conditions, a pair of views is enough to obtain a full set of possible views by following the line that joins their optical centers (baseline) without reconstructing explicit 3D models. Test results show the viability of the proposed algorithm for simple scenes (an object with a simple geometry, which is opaque, and does not present any occlusions). [ABSTRACT FROM AUTHOR]

In this paper, we present a modification of the repetitive random search algorithm. In our proposal, we change the fixed parameters which values are set by the user, by deterministic values following a chaotic map. The proposed algorithm is used to optimize four well known test functions for 10, 20 and 30 dimensions. For all cases, our proposal converges to better points that the optimal points obtained using the traditional version with fixed values in the parameters. The obtained results encourage us to continue the development and testing of the proposal algorithm with a major suite of test functions, and to compare it with other well established heuristic algorithms.

This paper presents an extension of Gauthier's algorithm, which solves the problem of searching for the multivariable minimal realization starting from square transference matrices. Previously, the algorithm incorporates the coprime fractions developed with Silvester matrices and qr factorization. Since the coprime fractions have a special relation with matrices in polynomial fraction, they show their differences by analyzing them independently. The general features are set out, and the developed functions named, in order to emphasize the different search paths and their representation in state space (neither of which are not unique) for the coprime fraction. For demonstration we used a multivariable dynamic system, where the efficiency and limitations of the developed algorithm are checked based on the functions performed with the Matlab® Control Toolbox.

The life cycle sofware duration depends essentially on the efective effort used for its implementation and moreover for its maintenance. The underlooking on Database Reverse Engineering (DBRE) is an increasing fact-day, due to the opportunities provided by news paradigms of the software development industry. Database Reverse Engineering, as the aim, is an imperfect process driven by imperfect knowledge, so that many techniques and tools are based on some assumptions as the precondition of the purpose. Consequently, the result is just an effective and efficient method for some identified databases systems (DS). Inside the relational database (RDB), the semantic structure reconstruction is an actual task-investigation. Some recent algorithms were proposed, which don't take any a-priori knowledge, and involve mapping techniques preserving this semantic information. This paper intends to give a classification of some relational DBRE occurred during lasts years. [ABSTRACT FROM AUTHOR]

This paper formulates an interpretation of computability from the perspective of realist conceptualism. The key notion within this theory is that of a computable concept, where a concept is a cognitive capacity of a certain sort. Differences and connections between the conceptualist interpretation and the classical one, customarily referred to as the theory of effective computability, for which the key concept is that of an algorithm, are shown in the text. Consequences of the idea that the content of computable concepts can be expressed in algorithms are explored. An appendix briefly outlines how the present conceptualist approach differs from two other non-classical interpretations of computability, the intuitionist and the representationist.
