The wine sector is a growing industry with an important share of the revenue resulting from export markets. Due to its cultural nature, wine exporting requires specific firm and managerial capabilities. As such, traditional approaches to the factors influencing export performance must integrate the specificities of wine as a product.

This study, based on a sample of 93 wine producers, develops and tests, using structural equation modeling, specifically the partial least squares method, a conceptual model of the influence of internal factors, external factors and partner relationship capabilities in export performance.

Results reveal that internal factors and partner relationships have an impact on the firm’s noneconomic performance which influences economic performance. It is also shown by the results that external factors do not affect the noneconomic performance or economic performance. Moreover, the results show the moderation effect of the noneconomic variable. Internal factors and relationship capabilities have an impact on economic performance considering the mediation effect of the noneconomic performance. Overall, firms’ internal factors and relationship capabilities are crucial to achieve better export performance for Portuguese wine companies.

This study combines the theories of SCP, resource-based view and relational or behavior perspective to present a novel approach to export performance by analyzing the external and internal dimensions of the firm in relation to both financial and nonfinancial performances.

El sector vitivinícola es una industria en crecimiento con una parte importante de los ingresos procedentes de los mercados de exportación. Debido a su naturaleza cultural, la exportación de vino requiere unas capacidades empresariales y de gestión específicas. Por ello, los enfoques tradicionales de los factores que influyen en los resultados de la exportación deben integrar las especificidades del vino como producto.

Este estudio, basado en una muestra de 93 productores de vino, desarrolla y pone a prueba, mediante un modelo de ecuaciones estructurales, concretamente el método de mínimos cuadrados parciales, un modelo conceptual de la influencia de los factores internos, los factores externos y las capacidades de relación con los socios en los resultados de exportación.

Los resultados revelan que los factores internos y las relaciones con los socios influyen en los resultados no económicos de la empresa, que a su vez influyen en los resultados económicos. Los resultados también muestran que los factores externos no afectan al rendimiento no económico ni al rendimiento económico. Además, los resultados muestran el efecto de moderación de la variable no económica. Los factores internos y las capacidades de relación tienen un impacto en el rendimiento económico que arroja el efecto de mediación del rendimiento no económico. En general, los factores internos y las capacidades de relación de las empresas son cruciales para lograr un mejor rendimiento de las exportaciones de las empresas vitivinícolas portuguesas.

Este estudio combina las teorías de SCP, RBV y la perspectiva relacional o de comportamiento para presentar un enfoque novedoso del rendimiento de las exportaciones, analizando las dimensiones externas e internas de la empresa en relación con el rendimiento financiero y no financiero.

To describe water absorption by the rice grains over time, diffusion and empirical models were used. Also, an optimization software was developed in this study to determine parameters and their uncertainties for the diffusion models (LS Optimizer, for partial differential equations). Parameters (and their uncertainties) for empirical models were determined by LAB Fit Curve Fitting Software.

Heat and mass diffusion phenomena are found in various processes of technological interest, including pasteurization, drying and water immersion of agricultural products, among others. The objective of this work was to study the process of water absorption by rice grains with and without husk, using diffusion and empirical models to describe the absorption kinetics. Rice grains were immersed (approximately 10 g for each experiment) in drinking water maintained at constant temperatures of 28, 40 and 50 C. In the experiments, the water contents absorbed by rice grains over time were obtained by the gravimetric method.

Among empirical models, Peleg was the most satisfactory to describe the kinetics of water absorption by rice without husk, while the Silva et alii model had the best statistical indicators for rice with husk. It was also verified that a diffusion model with boundary condition of the first kind showed the best (or equivalent) results in the description of all processes of kinetics of water absorption by rice grains, with and without husk. For grains without husk, the effective mass diffusivities were (1.186 ± 0.045) × 10⁻⁹, (1.312 ± 0.024) × 10⁻⁹ and (2.133 ± 0.028) × 10⁻⁹ m² min⁻¹, for the immersion temperatures of 28, 40 and 50C, respectively. For grains with husk, diffusivities were (0.675 ± 0.011) × 10⁻⁹ and (1.269 ± 0.017) × 10⁻⁹ m² min⁻¹, for temperatures of 28 and 50 C, respectively.

This work developed a solver for the diffusion equation in cylindrical geometry and presented the LS Optimizer software developed to determine differential equation parameters through experimental data sets.

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.

Despite the continuous development of Building Information Modeling (BIM) standards, not all of its dimensions are supported to the same extent. This is the case of Building Automation Systems (BAS) in which the features that are limited mostly to physical setup of devices are supported. These are largely insufficient to support modeling automation scenarios. The purpose of this article is to clarify the gap in the state of the art and define the need for further developments.

This article explores the existing gap in the literature and discusses the hypothesis of extending BIM to a wider support of BA concepts. Based on an assessment of scientific and technical literature, this study elicits the information requirements of BA and performs a gap analysis with current BIM standards, such as Industry Foundation Classes (IFC).

Our findings lead us to conclude that there is a lack of completeness regarding features from BAS automation and management levels. Furthermore, it is shown that IFC is the most adequate data model to cover BAS without losing its purpose, but there is still a considerable work that needs to be addressed in future research.

BIM standards such as IFC position themselves as natural candidates for modeling and exchanging information regarding BA. However, the extent to which BIM supports automation features has never been rigorously analyzed. This article explores the existing gap in the literature and discusses the hypothesis of extending BIM to a wider support of BA concepts. Based on an assessment of scientific and technical literature, this study elicits the information requirements of BA and performs a gap analysis with current BIM standards such as IFC.

This study aims to analyse the impacts of an institutional change process on a specific higher education institution in Europe and the trade-offs between the faculty perceptions of success and the organization image during this process, in light of the identity institutional theory.

The impacts of this institutional change are analysed and discussed based on in-depth interviews conducted with faculty members of the accounting department in which they reflected upon academic success vis-a-vis the career assessment system adopted, followed up by those faculty members’ answering an electronic questionnaire about organizational identity and image perception (Gioia et al., 2000).

Considering the individual perspectives, faculty are concerned about their vocations and aspirations, with feelings of apprehension and insecurity, perceiving the institutional goals as too high and potentially unattainable. By shifting the priority towards research, costs in terms of losing the institutional excellence in teaching might arise, which has been traditionally keen to the institute’s organizational identity and consistent with faculty’s perceptions of academic success.

As in any research endeavour, some limitations might emerge. First, the authors addressed the context of a specific business school, in a European country. It is certainly true that culture plays a role in terms of both organizational and national levels. The authors acknowledge this as a limitation. Nevertheless, this research takes a “local” stance, the logic of academic evaluation and its impacts on institutional and individual identity formation processes is a worldwide phenomenon. Second, in defining the authors’ selection criteria, the authors excluded the possibility of other voices to be heard, both in the department itself and in the business school. Regarding the department, the authors argue that those are the ones who could influence future decisions, considering that they are the only ones eligible for the governing bodies under the institute’s regulations. Regarding the business school, adding other department(s) means adding other discipline(s) to the authors’ analysis with specific and different dynamics of researching, publishing and teaching, which also impacts the expectations regarding career and academic success.

First, before beginning an institutional change process, it is necessary to assess the vocations and aspirations of its members. The solution requires to reanalyse academic career premises and to reconsider the weights given to each academic activity, or furthermore, to offer more than one career path, so as to make it flexible for each faculty to follow their vocations and aspirations or to adapt to life demands. Second, in terms of organizational identity and image, the challenge is to minimize the gap between the construed external image and the internal identity, striving to achieve a balance between teaching, research, outreach and service.

Because of the nature of the academic work, the authors propose that the application of the theory should be preceded by a careful consideration of what is academic success. The misalignments studied and reported here reveal a multilevel phenomenon, wherein individual academic identities are often in conflict with the institutional image. The authors’ study entails a contribution to the application of the identity institutional theory to academic institutions.

Fused Filament Fabrication (FFF) is an extrusion-based manufacturing process using fused thermoplastics. Despite its low cost, the FFF is not extensively used in high-value industrial sectors mainly due to parts' anisotropy (related to the deposition strategy) and residual stresses (caused by successive heating cycles). Thus, this study aims to investigate the process improvement and the optimization of the printed parts.

In this work, a meshless technique – the Radial Point Interpolation Method (RPIM) – is used to numerically simulate the viscoplastic extrusion process – the initial phase of the FFF. Unlike the FEM, in meshless methods, there is no pre-established relationship between the nodes so the nodal mesh will not face mesh distortions and the discretization can easily be modified by adding or removing nodes from the initial nodal mesh. The accuracy of the obtained results highlights the importance of using meshless techniques in this field.

Meshless methods show particular relevance in this topic since the nodes can be distributed to match the layer-by-layer growing condition of the printing process.

Using the flow formulation combined with the heat transfer formulation presented here for the first time within an in-house RPIM code, an algorithm is proposed, implemented and validated for benchmark examples.

The purpose of this paper is to develop simulation models for flexible‐printed circuit boards' flex‐rigid interfaces and to perform experimental tests in the laboratory in order to evaluate the cracking phenomena when these devices are submitted to thermal cycling.

A device was proposed in order to evaluate the reliability of flex‐rigid interconnections. Thermal cycling tests were performed in an environmental chamber and failure mechanisms investigated using optical and scanning electron microscope techniques. The failure modes were analyzed using computational modelling via the finite element method.

Through failure analysis, it was observed that device design and thermal expansion/contraction could contribute to the occurrence of high stresses in the copper pad connections. The simulation model proposed was able to identify the critical regions, as they had occurred in the tests. Thus, the qualitative approach may be considered successful enough to be applied in the early stages of design.

The materials proprieties were considered as being linear. Thus, in order to enhance the simulation models to provide a quantitative model for the evaluation of product life, non‐linear (visco‐elastic) behaviour in the material properties and a fracture model should be considered.

Typical causes of cracking failure in electronic devices are related to mechanical stress, moisture, heat from transportation and field use. Thus, finite element analysis is an important tool in order to evaluate the reliability of electronic components regarding these types of loads in the early stages of design.

The purpose of this paper is to assess the reaction of European stock markets after the UK's EU membership referendum (“Brexit”) on June 23, 2016.

The analysis focuses on asector level by using non-aggregate stock indices across EU-28, the UK and several country subsamples. An event study is performed in order to measure cumulative abnormal returns during the post-referendum announcement period.

The results indicate an unexpected small number of affected sectors across the country samples. A negative effect is observed in the financial sector across both the EU-28 and eurozone samples, whereas basic materials and health care sectors are influenced positively across the European region. Most of the sectors in the UK display a long-lasting positive effect, while the close trade relationships between the UK and selected European countries seem to partly constitute a driving force of sectors' abnormal stock returns after the referendum.

The results are useful for global investors, traders and portfolio managers in terms of whether short-term gains from investment choices across sectors can be achieved during periods of increased political uncertainty and whether investors distinguished between sectors.

This paper extends the Brexit literature by using, for the first time, European non-aggregate stock indices. It also contributes to the sector-specific contagion studies by identifying which sectors with similar and/or different industrial composition are more prone to political uncertainty caused by the Brexit vote.

This paper aims to describe the obtainment of Ti-6Al-4V parts with a hierarchical arrangement of pores by additive manufacturing, aiming at designing orthopedic implants.

The experimental methodology compares microstructural and mechanical properties of Menger pre-fractal sponges of Ti-6Al-4V alloy, manufactured by laser powder bed fusion (LPBF) and electron beam powder bed fusion (EBPBF), with three different porosity volumes. The pore arrangement followed the formation sequence of the Menger sponge, with hierarchical order from 1 to 3.

The LPBF parts presented a martensitic microstructure, while the EBPBF parts presented an α + ß microstructure, independently of its wall thickness. The LPBF parts presented higher mechanical resistance and effective stiffness than the EBPBF parts with similar porosity volume. The stiffness values of the Menger pre-fractal sponges of Ti-6Al-4V alloy, between 4 and 29 GPa, are comparable to those of the cortical bone. Furthermore, the deformation behavior presented by the Menger pre-fractal sponges of Ti-6Al-4V alloy did not follow the Gibson and Ashby model's prediction.

To the best of the authors' knowledge, this is the first study to obtain Menger pre-fractal sponges of Ti-6Al-4V alloy by LPBF and EBPBF. The deformation behavior of the obtained porous parts was contrasted with the Gibson and Ashby model's prediction.
