The purpose of this paper is to analyze and discuss the application of buffer zones as an urban landscape heritage management tool, using Rio de Janeiro as the main case study, in order to inform urban regulation around the sites inscribed as World Heritage Cultural Landscape and disclose its relevance to link urban planning, cultural heritage management and sustainable development.

The methodological approach encompasses: conceptual framework – contextualization of heritage protection theory, focusing on landscape protection and buffer zones; discussion: cross-national comparative overview of buffer zones conceptual framework on the international heritage protection policy; historical background and spatial analysis, through GIS mapping, of local heritage protection policy, tracing its evolution through time; examination of prospects and challenges of this management tool, including strengths, weaknesses, opportunities and threats, based on previous international, local experiences on natural and cultural heritage protection; and gathering of strategies for the implementation of buffer zones in local landscape management.

Core heritage sites and their buffer zones are integrated elements and act together to protect landscape significance and dynamic integrity (DI). In Rio de Janeiro, beyond the function of a caution zone, other important functions of landscape heritage buffer zones are to guarantee spatial and social connections of the protected sites, as well as the visual relationship between them and other significant urban landscape features. Strategies for the implementation of buffer zones in local landscape management should address the articulation of landscape protection governance; the conservation of visual, functional and structural identity quality and legibility and the monitoring of DI.

The methodology approach adopted in this study may also benefit from and foster further investigations, which could include the elaboration of a landscape management plan and an impact assessment inventory, refining the scale of study to the level of local watersheds, and a deeper examination of the popular cultural imprints within the World Heritage property buffer zone.

Strategies to the implementation of the Carioca Landscapes buffer zone include a gradation of protection and control of impacts according to the distance of the core sites (in the form of rings or layers). The buffer zone should help to preserve the character, significance, and DI of the protected sites and guarantee their spatial and social connections, as well as the visual and functional relationship between them and between other significant landscape features of the city. All those management strategies should be founded on the elaboration of a broad urban landscape management plan with the local society involvement.

In Rio de Janeiro’s specific case, bridging the vision of culture and nature as opposite poles and, transcending the social segregation through community involvement should certainly be among the main guiding principles to the application of buffer zones for supporting landscape sustainability. Therefore, the establishment of regulation criteria and parameters within the limits of the buffer zone must acknowledge that the (urban) landscape should carefully articulate the different social agent visions and local urban contexts.

The main contribution of this paper is to gather different visions of the role of buffer zones and disclose possibilities of conciliation between theory and practice concerning landscape protection, arguing for gathering natural and cultural heritage policies into the urban planning processes. Harnessed together, the suggested buffer zone implementation strategies may provide a proactive approach to Rio’s urban landscape protection and contribute to foster landscape sustainability and resilience. Although based on a specific case study, the adopted methodological approach may be transferable, with some adjustments, to other World Heritage properties, especially those located in urban areas under development pressures.

The singularity of being the first Chinese manufacturer of drug-eluting stents to arrive in Brazil and the country being selected as the company's first experience outside its home country motivated the interest in the study of this case, vis-à-vis with the characteristic of internationalization medical device companies according to the Uppsala model. Considering this context, the following research question was outlined: “How did Microport internationalize before the distribution of its stents product in Brazil?” The aim of the study is to investigate Microport's internationalization process for the distribution of its drug-eluting stents in Brazil.

Exploratory research under the qualitative method was adopted. It chose the single case study as a procedure for data collection, as it is a revealing, exemplary subject that offers opportunities for access to unusual research. The company MicroPort was chosen because in the period when Chinese medical device companies were focused on gaining market share in China, MicroPort began its international expansion, choosing Brazil as the first country to have its own subsidiary. It consists in the case of the internationalization of a high-tech EMNE in an emerging country that has institutional and cultural differences.

Taking advantage of new technology in highly internationalized environments favors its insertion; the internationalization of medical technology can expand according to the Uppsala Model, which does not explain internationalization, but rather its evolution. Cultural and behavioral issues reinforce that the development of the market for medical devices depends on local perspectives and values. The formation of an ecosystem in the local market for internationalization is observed. One implication of the study is that MicroPort's experience and the application of the Uppsala model for international expansion can serve as an important learning experience for Brazilian multinational companies.

Empirical analysis carried out in the context of a single company. Although the results can be used as lessons learned from the application of the Uppsala model for international expansion of EMNE in an emerging market, caution should be exercised when generalizing its findings. Future studies could carry out comparative cases considering other emerging multinational companies, from the same sector or even from different industries, investing in other emerging markets. There is a limitation of the fact that the case studied does not explore the concepts of the later stages of the Uppsala model.

High-tech EMNEs internationalizing in other markets need to adopt aggressive strategies. The need to adopt different strategies for supply chain operations according to the specificities of the markets in which they operate. Important contributions to the Uppsala model, with regard to the process of passing stages, learning and networking. The findings of this study have similarities to the process described as a sequence of distinct phases of activities.

A local top management team is essential to deal with institutional issues of government agencies when EMNE is internationalized in a culturally distant market. When there are major institutional differences between the country of origin and the host country, the autonomy in the management of the foreign subsidiary positively influences the acceleration of the internationalization process of companies in the high-tech sector. When there are major institutional differences between the country of origin and the country of destination, the use of local social networks positively influences the acceleration of the internationalization process of companies in the high-technology sector.

Regardless of these limitations, the study provided an exciting case of internationalization of a Chinese company in Brazil operating in a high-tech medical sector. The challenges for the internationalization of EMNEs continue, which makes it opportune for future studies to include more research in this area. The propositions suggested in the study may be the first step.

This study aims to investigate how small- and medium-sized enterprises (SMEs) perceive the benefits and obstacles with university cooperation for themselves and regional development, setting out from the personal relations the parts have formed.

A quantitative approach was adopted, using a sample of 336 Brazilian SMEs that had undertaken some cooperation with universities in the past years.

From structural equation modelling, results show that interpersonal relations interfere in the type of cooperation formed, these being a catalyst in formalizing the cooperation. These relations also interfere in the perception of barriers and benefits of cooperation for the firm.

The results are clearer in the firm domain and less so in the region, implying that university-SME cooperation does not yet present clearly disseminated benefits so that firms can be more aware of the results. The barriers to cooperation seem to be overcome by interpersonal relations but also by the contracts established since they were more evident in the informal type of cooperation.

This study provides more empirical evidence about these relations in a context of low socio-economic development, a topic which is still under-explored in the field of university-firm cooperation.

The growing presence of projectification is affecting more than its cradle, the industry, characterizing it as a broader phenomenon than initially envisioned. This study aims to provide a literature review on the concept.

The sampling process includes articles from two databases, Web of Science and Scopus, and a backward snowballing sampling through the references, entailing the analysis of 103 documents. The publications were analyzed applying bibliometric, content and semantic analyses both manually and with the assistance of VOSViewer, Bibliometrix, NVivo11 and Tropes v.8.

The results identified 55 definitions of projectification. The study synthesizes them in five levels of analysis to capture their main distinctive aspects, as follows: (1) Private Organizations; (2) Public Sector; (3) Academy; (4) Individuals (work and private life); and (5) Society. The paper concludes by depicting factors as general effects, negative effects, tensions, funding and knowledge, embedded within each level of analysis.

This work sheds light on the evolution of projectification concept, presents a multilevel analysis of its consequences and brings forward the related topics, which still require further investigation.

The purpose of this paper is to present the results of a particle swarm optimization (PSO) method applied in the design of a square-loop frequency selective surface (FSS) via the equivalent circuit model (ECM), considering the dielectric effective permittivity as a variable in the optimization problem.

In the optimization process considered, besides the FSS square loop geometric parameters, the thickness and relative permittivity of dielectric material used as support are included as variables in the search space, using for this a model of dielectric effective permittivity introduced by the authors in a previous work.

Square loops were designed and the obtained results were compared with designs reported in literature for applications in wireless local area network and long-term evolution 4G systems. The low computational cost is remarkable as well as the acceptable accuracy obtained with the proposed approach. The PSO method results were implemented with the ECM and compared with those obtained via Ansys – high frequency structure simulator commercial software simulations.

The lack of a model of dielectric effective permittivity for the ECM causes a restricted search space in the stochastic FSS design process limited to only geometric parameters, as it is reported in the available literature. The proposed approach simplifies and makes more flexible the design process, and allows guiding the FSS design to unit cell surface and/or dielectric thickness of small dimensions.
