Section 1 of the Asuncion Treaty sets up the Common Market of the Southern Cone (Mercosur). It establishes, inter alia, ‘the commitment of the Member Parties to harmonize their laws in the relevant areas, with a view to strengthening the integration process’. Such a harmonisation implies an intention to establish increasingly common criteria and similar patterns at a sub‐regional level to deal with a specific set of rules that are currently dissimilar.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

The consolidation process and morphology evolution in ceramics-based additive manufacturing (AM) are still not well-understood. As a way to better understand the ceramic selective laser sintering (SLS), a dynamic three-dimensional computational model was developed to forecast thermal behavior of hydroxyapatite (HA) bioceramic.

AM has revolutionized automotive, biomedical and aerospace industries, among many others. AM provides design and geometric freedom, rapid product customization and manufacturing flexibility through its layer-by-layer technique. However, a very limited number of materials are printable because of rapid melting and solidification hysteresis. Melting-solidification dynamics in powder bed fusion are usually correlated with welding, often ignoring the intrinsic properties of the laser irradiation; unsurprisingly, the printable materials are mostly the well-known weldable materials.

The consolidation mechanism of HA was identified during its processing in a ceramic SLS device, then the effect of the laser energy density was studied to see how it affects the processing window. Premature sintering and sintering regimes were revealed and elaborated in detail. The full consolidation beyond sintering was also revealed along with its interaction to baseplate.

These findings provide important insight into the consolidation mechanism of HA ceramics, which will be the cornerstone for extending the range of materials in laser powder bed fusion of ceramics.

Grass roots movements in relationships of cooperation and conflict between firms, communities, and government have an important role to stop a living city from disappearing. This chapter describes and analyzes the implications of the collective action used by grass roots movements in the defense of an old mining town, Cerro de San Pedro, of being disappeared due to the pollution of fresh watersheds by the operations of a mining company and the effects on the living city of San Luis Potosì, in the center of Mèxico.

This paper aims to identify the interrelationships of institutional factors that compose an entrepreneurial ecosystem (EE) in small towns that can potentially increase the attraction of franchises.

The authors analyzed 728 small towns with franchise chains that do not belong to metropolitan regions and are limited to populations of up to 50,000 inhabitants. Secondary data are obtained from the Brazilian Institute of Geography and Statistics. The data analysis technique used is Poisson regression.

A higher number of employed persons (H1), a higher savings (H2) and a higher number of educational institutions (H4) correlates with more franchise chains in small towns. The availability of institutional support (H3) does not correlate with the number of franchise chains. Regarding the interrelationships between factors, the interactive effect between two constructs is determined to cause a decrease in franchise chains, whereas interrelating three factors raises the number of franchise chains (R² = 72.3%).

The analysis identifies some environmental factors to be considered in market prospecting by franchise chains’ expansion managers. These factors constitute a relevant analytical model focused on the regional development of franchise chains.

Social contributions are directed to public policy professionals responsible for regional economic development, as emerging markets demand actions to encourage job creation when confronted with high unemployment rates and dependence on the informal economy.

The contribution of this paper is bringing EE to the debate of the institutional environment’s impact on new businesses. EE adds to the debate examining the interrelationships between different institutional factors. An EE not only identifies the factors, but also examines the interdependence of these factors, which can potentially explain the attraction of franchise chains in small towns.

This chapter provides an alternative interpretation of the emergence of the “Ramsey-Cass-Koopmans” growth model, a framework which, alongside the overlapping generation model, is the dominant approach in today’s macroeconomics. By focusing on the role Paul Samuelson played through the works he developed in the turnpike literature, the author’s goal is to provide a more accurate history of growth theory of the 1940–1960s, one which started before Solow (1956) but never had him as a central reference. Inspired by John von Neumann’s famous 1945 article, Samuelson wrote his first turnpike paper by trying to conjecture an alternative optimal growth path (Samuelson, 1949 [1966]). In the 1960s, after reformulating the intertemporal utility model presented in Ramsey (1928), Samuelson began to propound it as a representative agent model. Through Samuelson’s interactions with colleagues and PhD students at the Massachusetts Institute of Technology (MIT), and given his standing in the profession, he encouraged a broader use of that device in macroeconomics, particularly, in growth theory. With the publication of Samuelson (1965), Tjalling Koopmans and Lionel McKenzie rewrote their own articles in order to account for the new approach. This work complements a recently written account on growth theory by Assaf and Duarte (2018).

The concept of environmental diplomacy appears associated with events (conventions) promoted between states and transnational organisations to discuss aspects related to regulating the use of natural resources and regulating pollution. In this study, the authors intend to highlight the contribution brought to environmental diplomacy by leading television figure David Attenborough and his focus on the destruction of biodiversity by humans (the problem). It is intended to analyse the frames of his public interventions, comparing them with the prevailing frames in the UNFCCC policies.

A predominantly inductive method of qualitative and interpretative nature is used. In epistemological terms, the framing analysis stems from a social constructivist perspective. A theoretical model for frame analysis was defined by combining the frameworks proposed by Entman (1993) and Semetko and Valkenburg (2000) and considering previous studies (Anholt, 2015; Seelig, 2019). Analysis scrutinised a two-fold corpus comprising articles regarding actions and statements by David Attenborough published in The Guardian between 2018 and 2020, and the UN's legal framework for climate change.

The most prominent frames regarding climate crisis in transnational policies are responsibilities. Attenborough's calls for action highlight the frames of “morality”, “responsibilities” and “problems”. However, it is necessary to make a distinction between the discourse used in transnational treaties and that by Attenborough. In the former, discourse is more technical and impersonal, presented in a structure of legal diplomas and barely accessible to the public. In contrast, Attenborough's speech is more emotional, appealing and sometimes dramatic. His message is transmitted straightforwardly to the public in a pedagogical, personal tone.

The choice of high-profile personalities like David Attenborough as ambassadors has implications in the visibility of the environmental cause, and in the multiplication of initiatives that denounce environmental degradation.

This study explores and analyses the narrative construct regarding climate change as carried out by a trusted and respected media voice. The authors intend to contribute to understanding the amplification role of public figures in controversial issues and diplomatic matters. The main contribution of this study is to highlight the strategic nature of the choice of SDA by political powers to voice the drama of climate emergency.

With an ever-expanding focus on reading and mathematics, many elementary schools have chosen to reduce time previously reserved for social studies. Elementary teachers who understand both the relevance of social studies content and the effectiveness of interdisciplinary teaching regularly incorporate applicable history-based children’s tradebooks in their curricula. Locating developmentally appropriate books is simple. Teaching history using children’s literature can be effective. It can be counterproductive, however, if the selected book is replete with historical misrepresentations. Teaching historical thinking in elementary school is problematic no matter what the teaching tool, and there are few methodological roadmaps for elementary teachers. Here, I first suggest ways for teachers to nurture elementary students’ historical thinking using anecdotes from everyday activities and literature with themes germane to history and multiculturalism. Then, I suggest ways for elementary educators to locate and develop engaging, age-appropriate, and historically accurate curricular supplements. Using literature on Christopher Columbus as a reference point to facilitate young students’ historical thinking, I propose an interdisciplinary approach, discipline-specific historical literacy strategies, and history-themed authentic assessments.
