abstract = {Fused filament fabrication (FFF) is an additive manufacturing (AM) process that provides physical objects commonly used for modeling, prototyping and production application. The major drawback of this process is poor mechanical property due to the porous structure of final parts. This process requires careful management of coalescence phenomenon. In this paper, the major influencing factors during the FFF process of poly(lactic acid) (PLA) were investigated experimentally and with a numerical model. It has been shown that the polymer temperature has a significant effect on rheological behavior of PLA especially on adhesion of the filaments. An experimental set-up has been placed in the machine to have the cyclic temperature of the filament. A variation of the polymer temperature influences process parameters such as feed rate, temperature of nozzle and temperature of the platform. The results showed that the amount of polymeric coalescence (neck growth) rises when increasing the feed rate, the nozzle temperature, and the platform temperature. A model to predict the neck growth is proposed. It predicts a lower amount of neck growth value than obtained with experimentally. This difference has been explained as the effect of other phenomena, such as polymer relaxation time, pressure of the nozzle and especially cyclic temperature which is not taken into account in the model.},

abstract = {Nowadays, the agri-food sector is facing several challenges due to a rapid technological change which calls for knowledge sharing (KS) practices to enhance businesses' performance. This has spurred a collaborative approach and the creation of networks. Since there still is a paucity of research on the quality degree of KS, the purpose of this study is to offer an empirical research on the quality degree of KS by exploring outcome expectations and social exchange dimensions. Theoretically, it is examined by a double lens of social capital and social cognitive theory.},

abstract = {In this paper, a multiscale model of ductile damage and its effects on the inelastic behavior of face centered cubic polycrystalline metallic materials, such as the evolution of their crystallographic textures, are investigated. The constitutive equations are written in the framework of rate-dependent polycrystalline plasticity at the microscopic scale. Plasticity and damage are coupled through a ductile damage variable introduced at the scale of the crystallographic slip systems of each grain. When homogenized to the macro-scale, this becomes an approximate phenomenological measure of the macroscopic ductile damage which can describe the material degradation by initiation, growth, and coalescence of micro-defects. In this paper, thermally activated intergranular (or creep) damage is not taken into account. Both theoretical and numerical aspects of the model are presented. The model is implemented into a generalpurpose finite element code in order to analyze the effects of texture evolution and ductile damage initiation in the grains with favorably oriented slip systems. The capability of the proposed model to predict the plastic strain localization and the induced textural evolution, as well as the effects of the ductile damage and its evolution up to the final macroscopic failure are studied for a classical tensile loading path, applied to a representative volume element and to a 3D tensile specimen on which a parametric study has been carried out.},

abstract = {This work presents a practical detailed finite element (FE) approach for the three dimensional (3D) free vibration analysis of actual aircraft and spacecraft type lightweight and thin honeycomb sandwich panels. It consists of calling successively in MATLAB®, via a developed user friendly GUI, a detailed 3D meshing tool, a macro commands language translator and a commercial FE solver (ABAQUS® or ANSYS®). In contrary to the common practice of meshing finely the faces and core cells, the proposed meshing tool represents each wall of the actual hexagonal core cells as a single two dimensional (2D) 4 nodes quadrangular shell element or two 3 nodes triangular ones, while the faces meshes are obtained simply using the nodes at the core faces interfaces. Moreover, as the same 2D FE interpolation type is used for meshing the core and faces, this leads to an automatic handling of their required FE compatibility relations. This proposed approach is applied to a sample made of very thin glass fiber reinforced polymer woven composite faces and a thin aluminum alloy hexagonal honeycomb core. The unknown or incomplete geometric and materials properties are first collected through direct measurements, reverse engineering techniques and experimental FE modal analysis based inverse identification. Then, the free vibrations of the actual honeycomb sandwich panel are analyzed experimentally under different boundary conditions and numerically using different mesh basic cell shapes. It is found that this approach is accurate for the first few modes used for pre design purpose.},

abstract = {In this study, we use an evidence-based approach to examine the factors that determine the competitive advantage of dairy supply chains using evidence from the Chinese dairy industry. We focus on the quality assurance of dairy products, which is considered one of the fundamental influential factors. We investigate interrelationships among the identified determinants, which include dairy production behavior, dairy cow culture model, government regulations, corporate social responsibility, and quality assurance, and examine how these determinants influence the competitive advantage of dairy supply chains. We employ the structural equation modeling approach in which grouped observable variables that represent the identified determinants are extrapolated from primary data collected through a questionnaire survey. Our key findings show that by mediating the effects of dairy production behavior and the dairy cow culture model, government regulation and corporate social responsibility significantly affect the quality assurance of dairy products. In turn, dairy production behavior and the dairy cow culture model significantly affect the competitive advantage of the dairy supply chain via the fully mediated effects of the quality assurance of dairy products. Specifically, the dairy cow culture model helps ensure the safety and quality of milk supply, allowing core dairy firms to control product quality throughout the dairy supply chain. Our empirical study shows that the identified determinants interact to assure the quality of dairy products and enhance the competitive advantage of the dairy supply chain in China.},

Then, based on these results, the definition of performance indicators for multi-physical and multi-indicator SI evaluation are proposed and implemented on a computer-aided tool to predict roughness.

abstract = {As today, vehicles are equipped with wireless sensors and on-board computers capable of collecting and processing a large amount of data; they can communicate to each other via different communication types and through different relay nodes. Internet of Vehicles (IoV) routing protocols are deployed to monitor these communications with various strategies to achieve a high availability of communication. In this paper, we propose to extend an existing taxonomy representing the necessary criteria to build IoV routing algorithms, by adding two new important criteria: security aspect and network architecture. Enhanced vehicular routing protocols with different security mechanisms have been studied, compared, and classified with respect to the authentication, the integrity, the confidentiality, the nonrepudiation, and the availability of data and communications. Routing protocols using the software-defined networking (SDN) paradigm have also been reviewed in order to compare with those with traditional network architectures. Three types of SDN routing protocols, namely, centralized, decentralized, and hybrid control planes, have been analyzed. This survey will be useful for the choice of IoV routing protocols that take into account the flexibility, the scalability, and the intelligence of vehicular networks, as well as the security mechanisms against cyberattacks while being cost aware.},

abstract = {Purpose Entrepreneurial knowledge spurs innovation and, in turn, generates a competitive advantage. This paper aims to explore if entrepreneurial knowledge combined with the attitude to innovate can overcome the key ?imperfections? of the innovation process generated by dynamic, current technological progress in the knowledge-intensive sector. The ?imperfections? identified in risk management, asymmetric information in the knowledge management process and hold-up problems can all disrupt collaborative partnerships and limit opportunities for innovation. Design/methodology/approach A theory-building approach is applied which offers a case study analysis of two small- to medium-sized enterprises (SMEs). These two SMEs operate in Europe but in two different territories: the UK and Italy. The study explores three key imperfections, risk management, asymmetric information in the knowledge management process and hold-up problems, which occur in the innovation process. Findings The entrepreneurs face these imperfections by adopting an open innovation model. Notwithstanding, both entrepreneurs had to deal with all ?imperfections?, and their skills, attributes, attitude and aptitude allowed them to grow their business and continually develop new products. Therefore, the imperfections do not limit the innovative capacity of an entrepreneur but rather enhance their challengeable attitude. In this regard, the case studies induce a further analysis on entrepreneurial knowledge intertwined with entrepreneurial risk management and networking skills},

These network-connected smart devices or machine-learning algorithms transfer information on consumers to the Internet by small sensors and computing processors. Companies thus track consumers' behaviour and offer personalised products and services. However, consumers are still sceptical in using these devices due to privacy risks and a dearth of awareness about the technologies' perceived value. Therefore, to overcome these barriers, the research seeks to measure the relationships among the elements that affect customers' willingness and decisions to use IoTs-based products. On the basis of motivation theories, two categories of motivational factors are individuated: extrinsic factors such as entertainment and social interaction and intrinsic factors such as information acquisition, privacy risk, and technology readiness level. They are analysed using a sample of 782 early-adopter customers in Italy. The aim is to offer an explorative, quantitative study on the IoTs to enhance the existing knowledge and support business in the process of engaging more users and creating new personalised products. In line with this, the study's implications, limits, and recommendations for further research are presented.},

The establishment of key interorganizational relations thanks to signs of institutional and individual trust participates in the emergence of a new organization in an environment characterized by strong barriers to entry (national and international accreditations, media rankings, etc.). The application of theories borrowed from business networks and international entrepreneurship in the higher education sector is an original contribution to the research.

The work also describes the impacts of interrelated multiple sustainable constraints on optimal policy for the supply chain transfer price and profit allotment decisions. The case for the sustainable supply chain with multiple supplies assuming no competitions between suppliers is also addressed. Our findings suggest that government intervention plays a dominant role in governing the supply chain firms' behaviors in the context of environmental and public health sustainability. The profit allotment is determined through the process of negotiation of the transfer price interrelated with the government subsidy sharing between the supply chain firms.},

This Retrospective builds on the extensive subsequent research to show the importance of context in constructing satisfactory theoretical explanations of OFDI. Building on these foundations, we propose research challenges for the next decade on Chinese OFDI that transcend the Chinese context and have wider theoretical applicability. Examining alternative forms of social and economic organisation allows the creation of special theories of foreign direct investment nested within the general theory.
