Abstract
Modelling and designing modern power devices is more and more often performed with two dimensional numerical simulation of basic semiconductor equations. Well‐known simulators, such as PISCES, are powerful and versatile tools, including a lot of physical mechanisms and simulation possibilities. However, this ability to address a very wide range of problems is often paid for by long CPU times and long training periods. These considerations have led us to develop a new two‐dimensional simulator targeted for a very specific goal: the study of the voltage handling capability of high voltage structures. Solving only the Poisson equation allows implementation of very fast numerical algorithms. The calculus of the breakdown voltage is performed by the classical evaluation of ionization integrals, incorporating a new fast iterative technique and an original ionization integral paths determination. Simulation results and comparison with commercial simulator will be presented.

Abstract
Purpose
When coping with complex, but also possibly disruptive and open‐ended social dynamics, the anticipatory system idea, which was developed by Rosen in the realm of physical and biological system observation, remains a reference framework, but one that may need to be reinforced by other theoretical considerations. This paper aims at using a debate that took place in a specific foresight discussion arena on early detection and weak signal analysis, as a constructive epistemic detour to eventually contribute to such a reinforcement of Rosen's anticipatory system proposal.
Design/methodology/approach
The author aims at revisiting Rosen's framework with stimulating inputs drawing upon the early detection debates, by first assessing the original concepts brought up by Ansoff in the 1970s and 1980s and its further enhancements by contemporary scholars. A rather constructivist approach is then developed to weak signal analysis, aiming at emphasising the need, in analytical situations involving social system features, for reflexive stages and capacities. Bearing this requirement in mind, the productive value of the “framing” and “meta‐framing” notions is explored, in order to apply them to Rosen's anticipatory systems and possibly contribute to enriching his original concept.
Findings
How effective the framing and meta‐framing couple can be for a series of anticipatory issues is described in a detailed manner and, then more specifically, Rosen's anticipatory system concept is revisited in the light of those inputs, aiming at putting into perspective new options for research and anticipation activities in general.
Research limitations/implications
The paper is essentially conceptual and based on a rich but disputable detour by early detection and weak analysis issues so as to emphasise key reflexive references and method. However, most of this material is taken from domains rather untypical of Rosennean debates and in addition would need to be completed by a series of supportive cases, but that is beyond the scope and scale of this paper.
Practical implications
The paper sets clear distinctions and boundaries for when and when not to apply reflexive steps in a foresight exercise, including in the context of rolling out a Rosen type of approach. Research decision making both in the corporate and policy‐making contexts can benefit from such clues and supportive framework conditions.
Social implications
Social systems are typically complex and involve multiple perspectives and viewpoints; they concern a series of major challenges to be coped with locally or more globally, at environmental, political, cultural or technological level, and in that category of anticipatory endeavor, the framing/meta‐framing epistemic couple may be of great usefulness.
Originality/value
Although rather conceptual, the detour proposed by the paper aims at creating a reflexive distance and enriched capability to evaluate one's potential biases and blind spots in anticipatory modelling activities.

Abstract
Governance is becoming an increasingly important concept in European theoretical debates and in political practice as a new way to manage public policies, since the public sector reforms in the 1980s. However, the debate in Latin America has different characteristics than in Europe, so it is necessary to provide a critical review of the proposed agenda for the transformation of the state in the region, and of the transfer of the concept of governance by multilateral agencies. To understand these changes, this chapter examines three key areas of reforms in Latin America and the privatization of public services, new social policy proposals, and the decentralization process. This will help us understand the tension between normative models and specific patterns of governance that prevail in Latin America.

Abstract
International tourism is steadily growing. Some people welcome this growth which supports economic and social development. Others are suspicious and afraid of the threat which tourism could create for the tourist destinations, the loss of cultural identity and of social alienation to its society. Reality is more complex than these two contrary positions suggest. After analyzing the existent attempts to explain the social effects of tourism, this paper intends to illustrate the variability of these effects. In this regard, the globalisation of human activities and its consequences on cultural identity are taken into account.

Abstract
Purpose
This study aims to explore the ways in which management scholars affiliated with Peruvian universities navigate the tensions between global expectations and local realities in their research practices, drawing on their capitals and habitus.
Design/methodology/approach
Drawing on Bourdieu’s field theory, the authors analyse 25 in-depth interviews and a unique database of academic publications in the business and management field from 2000 to 2022. The analysis identifies the positions scholars occupy within the Peruvian management field and examines the factors influencing their research practices.
Findings
The authors find that the Peruvian management field is complex and unequal, where actors have different positions and interests, but are all influenced by a logic of academic dependency on the Global North. The authors identify three main positions held by scholars: transnational dominators, who accumulate greater resources and ignore local debates; dominated adaptors, who unsuccessfully try to imitate the dominant logic; and isolated innovators, who critique the dominant model but lack institutional support to develop alternatives.
Originality/value
This research presents an analysis of the Peruvian management field, a site often overlooked in international business studies. By examining scholarly practices, the authors reveal how academic inequalities are reproduced by the forces of globalization. The study underscores the urgent need for greater acknowledgement of regionally informed research, advocating for a more inclusive and diverse understanding in the field of management research.
