Fighting the drought. Based on this idea, for almost two centuries now the Brazilian State has elaborated policies and programmes intended to stimulate rural development in the semiarid region of the country. It is this idea which has nourished the illusion that immense infrastructures need to be built to capture, store and transport large volumes of water in order to supply production activities in the region. Associated with this proposal is the attempt to reproduce the same pattern of development adopted in other Brazilian biomes, the main characteristic of which is the use of monoculture practices on large properties managed according to entrepreneurial modes of production. However the rich social experience promoted by rural worker organizations in the region has challenged this model by proposing living with the semiarid (Convivência com o Semiárido) as the guiding principle for alternative trajectories of development. Inspired by the experience of territorial development under way in the Agreste da Borborema region of Paraíba state, the chapter shows that the evolution of these new paths of development depends on revitalizing and mobilizing locally available resources, such as ecological potentials, social mechanisms for organizing labour and for producing and sharing knowledge, local forms of connecting food production to consumption and so on. The text concludes by emphasizing the need to design and implant institutional frameworks that enable a more balanced distribution of power between the State and civil society organizations, thereby allowing the latter to assume a more substantial role in identifying and managing endogenous resources that underpin self-centred development strategies.

One of the key strategies applied by most manufacturers over the past few decades has been the aim of decreasing production costs, improving quality and shortening time to market. In this respect, the technique of Design for Manufacture and Assembly (DFMA) has proved essential for improving the design of products and gaining competitive advantage. However, in recent years, the basis of competition has shifted towards the quick delivery of more innovative products. As a result companies are now looking for ways to enhance their technical innovation and creative problem solving, but at the same time retain control over product cost and quality.

This study aims to develop a realistic 3D printing-based simulator for the training and planning of the left atrial appendage occlusion (LAAO) to be used in the cath lab.

Starting from a pre-operative computed tomography dataset of a patient already treated with LAAO, the model was obtained, consisting in the right and left heart, opportunely assembled to replicate the position and orientation of the patient's anatomy while lying on the cath lab table. Different 3D printing techniques and materials were used to mimic the interaction between the cardiac tissue and the clinical instrumentation. The simulator was tested in the cath lab under proper image guidance by three LAAO expert operators. The clinicians were required to assign a score in terms of realism to each material used to fabricate the fossa ovalis and the LAA.

The simulated interventions were successfully performed by the operators, who were able to navigate in the system and release the occluder device as during a real procedure. The intraoperative images acquired during the simulations were highly comparable with data from a real intervention, with a mean percentage difference below 10%.

This study demonstrated the feasibility of the proposed simulator to faithfully replicate the LAAO procedure and its potentiality to be used for multiple purposes, including the training of the young clinicians, the evaluation of the most complicated cases and the design of novel occluder devices, in a fully realistic setting.

The chapter introduces digital food hubs as disruptive business models in the agri-food system shifting away from the unsustainable industrialized and conventional food sector and moving toward a re-localized food and farming pattern. They are new digital business models developed to support small and mid-size farms with a value focus, forming new ways to leverage the technology as a facilitator for coopetitive organizational forms. Indeed, they respond to a competitive strategy constituted by a “value strategy” oriented to the production and distribution of “shared value.” Second, they are based on an “organizational strategy” that shifts from individual competition to “coopetition” through the development of local “strategic networks” among small size producers. Central to the development of these business models is the digital disruption that has offered the space for the creation of unconventional exchange and transaction mechanisms distinguishing them from the already existing traditional ways of work. The agri-food markets exhibit structural holes that impede small farms from connecting with local consumers. This is due to a lack of material infrastructures and organizational forms on behalf of small farms that cannot reach the consumers, as well as the concentration of power in the hands of a restricted numbers of distributors, which causes the unequal redistribution of the economic value and impedes small farms accessing the food market. The advent of the digital technology is reshaping the market relationship by allowing out centralized intermediaries and creating new bridges between producers and consumers.

During the last two decades the share of foreign-born residents in Italy has grown considerably, from just over 1 percent to about 8 percent. This chapter seeks to clarify the status of immigrants in Italy by examining the evolution of their economic situation and, in particular, the presence of economic hardship. Poverty is measured by considering not only the usual income-based indicators but also others that take into account households’ real and financial wealth. The picture that emerges is one of a higher incidence of economic hardship among immigrant households that strongly affects the dynamics of poverty nationwide. The economic gap with respect to natives appears to increase in the years considered, but the condition of poverty is not more persistent for immigrants than for Italians.

Additive manufacturing is today a viable industrial solution alongside traditional processes. Techniques like selective laser sintering (SLS) address the issues of digital production and mass customization in a variety of materials. Composite parts can be obtained with specific functional and mechanical properties. Building orientation during additive manufacturing often causes anisotropy of parts' properties that is still unspecified in technical information. The purpose of this paper is to investigate the mechanical performances and failure mechanisms of an aluminium‐filled polyamide and of a new alumina‐polyamide composite produced by SLS, in comparison with unfilled PA.

A specific focus is set on the evaluation of primary and secondary anisotropy in the case of metal or ceramic filler, as well as on the specific contribution of powder distribution modes and joining phenomena. Macroscopic mechanical tests and the observation of joining and failure micro‐mechanisms are integrated.

The results prove the absence of relevant anisotropy amongst specimens that are produced with the axis parallel to the plane of powder deposition. Samples whose axis is parallel to the growth direction Z, instead, reveal a significantly different response with respect to other orientations.

An original explanatory model is assumed and validated, based on an anisotropic distribution of the reinforcing particles during parts' production, which determines the efficacy of the strengthening mechanisms during crack propagation.

This study aims to empirically investigate how knowledge paradox affects collaboration performance. Knowledge paradox, which arises from the simultaneous need for knowledge sharing and protection, is common in interorganizational collaboration. Using the ambidexterity perspective, this paper aims to reexamine the effect of the knowledge paradox on collaborative performance to explore the moderating roles of structural and contextual ambidexterity.

This study used a sample of 153 firms involved in vertical and horizontal collaboration, collected via questionnaires. Hypotheses were tested using hierarchical regression analysis.

This study demonstrates that the stronger the knowledge paradox is, the higher the potential for value creation. Thus, knowledge paradox has a positive impact on collaborative performance. The functions of structural ambidexterity and contextual ambidexterity strengthen this positive relationship.

This paper not only expands the theoretical application of the knowledge paradox and ambidexterity theory in the context of interorganizational relationships but also provides significant managerial implications. By comprehending the dynamics of the knowledge paradox and the role of ambidexterity, managers can make well-informed decisions to enhance their collaborative performance.

This chapter provides insights into the distribution challenges faced by alternative food networks (AFNs) in Japan. Consumers in Japan are showing increasing interest in supporting and buying directly from farmers, reflecting a growing demand for local food production and consumption. This trend parallels the increasing popularity of AFNs which are often touted as distribution models that seek to reconfigure the relationship between producers and consumers. Although AFNs are defined as a bottom-up response to the unsustainable nature of the industrial food system and the exploitative trade relations that are embedded within global food supply chains, there is little in the literature regarding challenges that emerge when scaling AFNs. This chapter focuses on the distribution challenges that emerge for AFN models that exist outside of direct market transactions, by comparing AFN models in Japan with a local wholesale market system that exists within the conventional, mainstream food system. Based on an analysis of the nuances and complexities that AFNs face in coordinating aggregation and distribution, we argue that the promotion of local food systems can also benefit existing conventional food systems, by leveraging the infrastructure of local wholesale markets. The distribution logistics and fundamentals of parity pricing from the wholesale market system would enable AFNs in Japan to establish a more accessible and sustainable food system. Using four case studies, including a local wholesale-market and three AFN models that distribute agricultural products from rural to rural, and rural to urban areas located in the Kansai region of Japan, we deepen the discussion of how small-scale farmers and their involvement in AFNs can better support sustainable food system transformation.

This paper aims to develop a deep characterization of PA‐Al₂O₃ composite for selective laser sintering (SLS). Tension test is used to determine main mechanical characteristics of the material, both at room temperature and at 100°C. An accurate knowledge of the parts' performances as a function of the building orientation, is fundamental to understand the manufacturing anisotropy. Particular attention is dedicated to the joining and failure micromechanisms ruling the macroscopic characteristics, on the basis of the knowledge developed by the authors on SLS of both metal and polymeric powders.

Specimens have been built with different orientations in regard to powder deposition plane and laser path. Tension test is used to determine main mechanical characteristics of the material, both at room temperature and at 100°C. A particular attention is dedicated to the joining and failure micromechanisms ruling the macroscopic characteristics of the composite material by means of optical and scanning electron microscope (SEM) observations.

The sintered material shows an evident anisotropy in the growth direction (z‐axis), as well as it seems to be not sensitive to the sintering direction at room temperature (x, y, xy). At 100°C the effect of sintering direction becomes more evident and a different behaviour results considering x‐ and y‐direction, respectively. Accurate SEM characterization has been carried out to understand the effect of the manufacturing anisotropy on the mechanical performances, both in terms of additive construction and laser sintering strategy. The observation of the rupture surfaces showed that cracks originate from the external surface and propagate initially by the ductile failure of the polymeric matrix, up to the sudden fracture of the whole section.

Previous studies concerning polyamide charged parts confirm the importance of fabrication parameters and geometry on the final performances, due to anisotropic heat supply and transfer phenomena. The originality of the paper is in the investigation on both at room temperature and at 100°C. Moreover, a model is proposed where it is hypothesized that the layer‐by‐layer construction is only marginally responsible of the anisotropic behaviour of the material.
