Self-Organized Criticality in a Bulk Driven One-Dimensional Deterministic System
We introduce a deterministic self-organized critical system that is one
dimensional and bulk driven. We find that there is no universality class
associated with the system. That is, the critical exponents change as the
parameters of the system are changed. This is in contrast with the boundary
driven version of the model [M. de Sousa Vieira, Phys. Rev. E 61 (2000) 6056]
in which the exponents are unique. This model can be seen as a discretized
version of the conservative limit of the Burridge-Knopoff model for
earthquakes.Comment: In honor of Constantino Tsallis in the celebration of his 60th

the role of intercultural mediation
Migration is generally described as a process that is nationally specific and that have
features common to several countries. This has been shown by several authors through
comparative research that compares the migration process of the same immigrant group to
several countries (among others, Engbersen, Snel, & de Boom, 2010) or which scrutinises the
migration realities of different countries (Zimmermann, 2005). Most of these studies are about
geographically near countries, which are part of the same political system (the EU), and that
have an established (albeit differentiated) welfare system. These proximities (geographical, but
also political and social) allowed the authors of these studies to conceptualise the existence of
several migration models or regimes: the southern European model (Baldwin-Edwards, 2012),
the Iberian model of Migration (Malheiros, 2012); the intra-EU mobility regime (Engbersen
et al., 2017). These migratory regimes are intertwined by migrant integration models or by
different approaches to increasingly diverse populations. Although these are often identified
as ‘national models of integration’, they do not fail to integrate the developments that have
been recorded in the last decades in the international contexts in which the countries are
inserted. Throughout the present text, the Portuguese experience in dealing with immigrant
integration is used to reflect on the development of intercultural policies and practices, and
on the role of intercultural mediation.
The article is structured in the following way: in the introductory section we will review the
discussion on interculturalism; in a second section the Portuguese immigration context will
be presented; in a third section the integration of immigrants in the country will be analysed,
given special attention to the development of policies that support immigrants’ integration
process. In the fourth section, the role of intercultural mediation for the integration of
immigrants will be considered.info:eu-repo/semantics/publishedVersio

STRATEGY AS DISCURSIVE PRACTICE IN A BRAZILIAN PUBLIC UNIVERSITY: A LOOK UNDER THE PERSPECTIVE OF CRITICAL DISCOURSE ANALYSIS
The aim this article a critical discursive analysis of the “management plan” genre of a public institution of higher education, from 2012 to 2015, located in southeast Brazil. The aforementioned plan is inserted in the discursive practice of strategic management, specifically the institutional, bureaucratic management, and is used as an instrument for decision-making. The goal of this analysis will be to discuss the first step of the “management plan”, named “organizational policies”. We can see that, while elaborating declarative sentences, there is an evaluation of the statements regarding what is to be considered relevant to the institutions by means of the ideological discourse on neoliberal ideals and market behavior. The adoption of market-oriented managerial tools has been a constant in public administration. The public administration looks for bases of organizational practices in the private sphere. This mimicry is still present in the field, and the search for new managerial practices still crosses the imaginaries of the public managers. However, the increasing incorporation of a market-oriented, neoliberal logic, mainly in the adoption of strategic planning, can still be verified. The conclusion presented in this paper serves to foment the debate on the strategies formulated for the Brazilian public service and the methodological applicability of the critical discourse analysis. This meets the emerging need to systematize and integrate distinct theoretical and methodological approaches in the field of organizational studies when strategy is studied as a social and discursive practice
