This paper aims to study the corrosion protection of 410 stainless steel (410SS) cracked by fatigue tests. The purpose of this study is to show that using polymeric coatings, it is possible to reduce the corrosion rate in metallic structures in operation.

Poly(3-hexylthiophene) (P3HT)/poly(methyl-methacrylate) (PMMA) composite was used as a coating to protect the cracked 410SS in the corrosive environment 0.5 M NaCl at 25°C and 80°C. Physicochemical characterization was carried out by adhesion tests, thermogravimetric analysis, nuclear magnetic resonance and size exclusion chromatography. Surface morphology was studied before and after the electrochemical tests by scanning electron microscopy. Uncoated and coated cracked 410SS were characterized by DC electrochemical techniques: linear polarization resistance and potentiodynamic polarization curves.

P3HT/PMMA coating reduced corrosion rate and crack propagation of 410SS in the corrosive medium NaCl 0.5M. The P3HT/PMMA coating increased the polarization resistance by one order of magnitude and decreased the corrosion current density by one order of magnitude, relative to the values obtained with uncoated cracked 410SS. The coating helped to have a less damaged surface and less crack propagation on the cracked 410SS. The feasibility of increasing the useful life of cracked metal structures in a saline environment was demonstrated through polymeric composite coatings.

In the literature, no works were detected that report the use of organic coatings to protect cracked metals against corrosion. This is the first reported work on the corrosion protection of 410SS in a saline medium using coatings based on P3HT/PMMA.

This study examines the motives and enabling factors regarding reverse factoring (RF) adoption in the automobile industry's supply chain.

This is a qualitative case study based on in-depth interviews with financial institutions in two countries having different statuses within the automobile industry global value chain: Mexico as a peripheral and Spain as a semi-peripheral country.

The RF is more widely deployed in Spain than in Mexico. The differences in the adoption of RF between the two countries stem from the availability of programs for suppliers at different supply levels, their efficient implementation and a robust regulatory framework, but especially from the cooperative approach adopted. The motives and enablers of RF adoption in the automobile industry can be explained under a framework of different supply chain management models. The RF programs driven by self-interest financial motives are characterized by an asymmetric distribution of benefits among supply chain participants. The RF programs that combine self-interest with cooperative motives are partially characterized by balanced benefits. In addition, they favor involvement practices and strengthen long-term relationships among supply chain participants. In this cooperative approach, trust, transparency and especially sharing information are considered relevant enablers. Finally, the specific automobile industry's features that determine RF adoption are linked to the structure and governance mode of the supply chain. The structure in terms of length – multiple supply levels – conditions the design of RF programs based on the buyer's position in the supply chain. The governance mode, particularly how the relationships are established, conditions the factors and requisites for efficient adoption of the RF programs.

This research analyzes the RF framed in the dynamics of buyer–supplier relationships and different models of supply chain management, allowing us to identify cooperation motives and their impact on RF adoption, beyond the traditional economic and financial motives highlighted by previous literature.

Purpose – The purpose of this study is to examine the influence of technological resources and external research partners on the export performance of Italian high-tech small and medium firms (SMEs).

Methodology/approach – Drawing on the resource-based view as theoretical framework and deriving hypotheses from the export management literature, we used a sample of Italian manufacturing firms to run a two-step analysis. First, a Levene's test is conducted to assess whether SMEs operating in the high-tech sectors differ from those operating in other manufacturing sectors. Second, employing ordinary least squares (OLS) regression we analysed which technological resources and external research partners best discriminate the export performance of high-tech SMEs.

Findings – Our empirical results revealed that: (1) the use of output rather than input measures of innovation better captures the contribution of technological resources on export performance of firms in our sample; (2) product innovations positively and significantly affect the export performance of technology intensive SMEs; (3) among external research partners, universities provide positive spillover effects on their export performance.

Originality/value – This study provides the heterogenic perspective of the high-tech sectors when attempting to explain the influence of technological resources and external research partners on the export performance of SMEs. Second, the study expands the traditional measures used in the literature for firms’ technological resources and it comprehensively analyses innovative inputs and innovative outputs while exploring whether innovative efforts have had a measurable effect on the export performance of high-tech SMEs.

Cuban education under the direction of the State guarantees education for all. This allows achieving equality and full social justice in order to train men and women capable of facing contextual demands, within a social model that aspires to form their citizenship in corresponding to the historical tradition and contemporary demands within a global system. This educational process takes place within difficult economic conditions and a complex international scenario, which affects the Nation in a particular way because it is a developing country. In this work, an evaluative analysis of Cuban educational policy in its development in the last six decades is carried out with the purpose of demonstrating its distinctive features consolidated in the historical evolution of an educational system that maintains its development in complex economic situations and improvement based on the changing demands of society. This analysis considers both the national and global levels, science, technology and the references of pedagogical sciences, without renouncing the purpose of guaranteeing by the State a free, inclusive and quality education for all its citizens throughout life.

This paper aims to investigate the extent to which locating primary industry subsidiaries in politically unstable countries impacts their survival. The authors argue that foreign multinational enterprises in less stable political environments can shape policies that are impactful on the costs of operating in primary industries and avoid compliance with more stringent policies at home.

Using a sample of 753 primary sector investments of Japanese multinational enterprises during the period 1986 to 2013, the authors conduct a parametric survival analysis of the relationship between political stability and subsidiary survival.

Political instability has a slight, curvilinear relationship with subsidiary survival, such that both high and low stability are associated with lower exit hazard, while moderate levels of stability increased exit hazard. This nonlinear relationship is stronger for efficiency-seeking subsidiaries, and weaker for market-seeking subsidiaries.

This research contributes to the debate around the pros and cons of globalization by examining the extent to which firms benefit by offshoring primary sector investments to avoid more costly legal requirements at home. The results suggest that this non-market strategy should be mitigated through appropriate policy measures and provides evidence that those policies already implemented are effective.

This study aims to evaluate the impact breaking energy of the parts manufactured by the fused filament fabrication (FFF) method. The evaluation considers the use of the epoxy resin coating, different materials and different printing orientations.

The authors developed an experimental statistical design using 54 experimental trials. The experiments’ output variable is the impact break energy of the parts manufactured by the FFF method. The input variables for the experiments consist of an epoxy resin coating (XTC-3D®, generic resin and without resin coating), different filament materials (nylon + carbon fiber, polyethylene terephthalate and polycarbonate) and different printing orientations (flat, edge and vertical) used. The authors carried out the tests following the EN ISO 179-1.

The use of resin coating has a significant influence on the impact energy of parts manufactured using the FFF method. The resin coating increases the impact resistance of parts processed by FFF by almost 100% of the value as compared to the parts without a resin coating. Post-processing is useful on ductile materials and increases impact breaking energy at weak print orientations.

This research opens a new opportunity to improve the mechanical properties of parts manufactured using the FFF method. The use of a resin coating reinforces the parts in weak print orientation.

In this paper, the authors examine the impact of Industry 4.0 (I4.0) technologies on the relationship between total productive maintenance (TPM) practices and maintenance performance.

Data collection was carried out through a multinational survey with 318 respondents from different manufacturing companies located in 15 countries. Multivariate data techniques were applied to analyze the collected data. Diffusion of innovations theory (DIT) was the adopted theoretical lens for our research.

The authors’ findings indicate that I4.0 technologies that aim to process information to support decision-making and action-taking directly affect maintenance performance. Technologies oriented to sensing and communicating data among machines, people, and products seem to moderate the relationship between TPM practices and maintenance performance. However, the extent of such moderation varies according to the practices involved, sometimes leading to negative effects.

With the advances of I4.0, there is an expectation that several maintenance practices and performance may be affected. Our study provides empirical evidence of these relationships, unveiling the role of I4.0 for maintenance performance improvement.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

“When James Boswell returned from a tour of Corsica in 1765 he wrote: ‘It is indeed amazing that an island so considerable, and in which such noble things have been doing, should be so imperfectly known.’ The same might be said today of Puerto Rico.” Thus began Millard Hansen and Henry Wells in the foreword to their 1953 look at Puerto Rico's democratic development. Four decades later, the same could again be said about the island.
