From a sociolinguistic perspective, greetings and farewells are part of what Goffman (1963) calls the ethnography of encounter. These encounters are not randomly made. They are governed by a set of strategies which enable participants to enter and exit conversations in a socially accepted manner. Such strategies are tackled within the scope of conversation analysis, henceforth CA, which is an approach that studies talk in interaction. It grew out of the ethnomethodological tradition in sociology, embracing both verbal and non-verbal conduct. This approach is initiated during the late 1950s of the last century by the works of Harold Garfinkel and Erving Goffman, then, developed in the late 1960s and early 1970s by the sociologists Harvey Sacks, Emanuel Schegloff and Gail Jefferson. Today CA is an established method used in sociology, anthropology, linguistics, speech-communication and psychology. This study is going to detect entry and exit strategies in English and Arabic by analyzing two episodes of ‘The Doctors’ show in its American and Arabic versions. The study conveys this topic on two interrelated scales as it employs sociolinguistic and discourse perspectives altogether, discussing how the two approaches cooperate to give a comprehensible view of the nature of entering and exiting conversation. Meanwhile, the data to be analyzed does not convey an ordinary type of conversation but a special kind of conversation, that is called institutional talk. This involves some specialization and re-specification of the interactional relevance. It refers to conversations that take place under focused and specialized conditions like media, courts, educational institutions and health establishments (Gumperz, 2001: 218). For the most of our knowledge, such type of conversation is not expected to show everything about talk in interaction, yet, it shows a big deal of conformity to the premises of conversation analysis, and it appears to have a good amount of flexibility.

En este documento se describe el desarrollo e implementación de un modelo para simular computacionalmente la dinámica del crecimiento y migración del cáncer cervicouterino, considerando sus principales características: proliferación, migración y necrosis, así como sus etapas de desarrollo. El modelo se desarrolló mediante un autómata celular con enfoques paralelo y secuencial. El autómata celular se basó en el modelo de Gompertz para simular las etapas de desarrollo de este cáncer, el cual se dividió en tres etapas cada una con diferentes comportamientos durante la simulación. Se realizó un diseño experimental con parámetros de entrada que se seleccionaron a partir de la investigación literaria y su discusión con médicos expertos. Al final del proceso de investigación, se logró obtener un algoritmo computacional de simulación muy bueno comparado con el modelo médico de Gompertz y se encontraron los mejores parámetros para su ejecución mediante un diseño factorial soportado estadísticamente. This paper describes the development and implementation of a model to computationally simulate the growth and migration dynamics of cervical cancer, considering its main characteristics: proliferation, migration and necrosis, as well as its stages of development. The model was developed by means of a cellular automaton with parallel and sequential approaches. The cellular automaton was based on the model of Gompertz to simulate the stages of development of this cancer, which was divided into three stages, each with different behaviors during the simulation. An experimental design was carried out with input parameters that were selected from literary research and its discussion with expert physicians. At the end of the research process, a very good simulation algorithm was obtained compared to the Gompertz medical model and the best parameters for its execution were found by means of a statistically supported factorial design.

Subject. This article analyzes the business processes in the insurance company, using the method of their operation with the selection of key areas of activity. Objectives. The article aims to describe certain business processes in insurance, highlighting participants, lines of activity, and the sequence of procedures. It analyzes the business process Settlement of Losses, which is one of the significant business processes in the insurance company. Methods. For the study, I used the methods of induction and deduction, analogy, and the systems approach. Results. Based on the analysis and description of business processes in the insurance company and the identification of key elements and steps in terms of the effectiveness of decisions, the article identifies the checkpoints of Entry and Exit, activity direction, and resources of the Settlement of Losses process. Conclusions. The application of the categories that split business processes makes it possible to develop step regulation for all processes and acceptable control procedures for different operations. The presented checkpoints at different steps of the business process will help identify weaknesses and eliminate them by re-checking the point.

The globalization of the economy encourages massive population displacements and inevitably generates a cosmopolitization of societies. This leads to concern, misunderstanding and rejection. The most vulnerable social groups in society can perceive the population as intruders and enemies in social competition. Undoubtedly, the extreme spatial instability of fishery resources is among the many factors affecting migration dynamics. Various reasons for the mobility of fishermen are relevant around this concept. These include aspect related to traditions, to the capitalisation of activity, to technological innovations, and to innovation exchanges concerning the location of fish stocks. This article reflects on spatial increase of fishermen’s. The analyse are part of the paradigm of the sustainable management of common renewable resources, in particular fishery resources. It presents three lines of analysis: the reason for mobility; the choice of destination; and are the integration into host units.
