The purpose of this paper is to compare the fluid dynamic performance of two Aqueous Humor (AH) ocular drainage devices, the SOLX® Gold Micro Shunt (GMS) and the novel Silicon Shunt Device (SSD), implanted by surgeons in human eyes to reduce the IntraOcular Pressure towards physiological values, by draining the AH from the Anterior Chamber to the Suprachoroidal Space, to cure eyes with glaucoma.

The generalized porous medium model is solved to simulate the AH flow through the two ocular drainage devices and the surrounding porous tissues of the eye.

In the GMS, probable stagnation regions have been found, due to the very small AH velocity values inside the device and to the surrounding tissues, creating possible blockage and malfunction of the device. The simple microtubular geometry of the novel SSD allows to have a regular AH flow and to choose shunts with different diameters and/or with the presence of radial holes, based on patient needs, with consequent reduction of post-operative complications.

The present model will be further developed taking into account the insertion of the present drainage devices inside the anterior section of the eye. The present results show the comparative fluid dynamic performance of the two shunts considered, and can be useful for surgeons to choose the adequate shunt, based on the required AH flow rate for a specific patient.

The present numerical approach, employing the generalized porous medium model, represents a useful tool to study the fluid dynamics of ocular drainage devices and to design these shunts, to reduce post-operative complications.

The generalized porous medium model is here applied for the first time to simulate the interaction of ocular drainage devices with the surrounding porous tissues of the eye.

Following the line traced by two previous works of Albino et al. and Messeni Petruzzelli, the paper aims to analyze how technology districts reach and acquire external competencies and capabilities by means of organizational and cognitive proximity. This allows districts to modify their geographical boundaries and evolve into technology clusters.

The research design is based on a case study methodology. In particular, two actual technology districts are analyzed, namely Castel Romano and Toulouse, in order to show how they use organizational, and cognitive proximity to acquire external knowledge sources and re‐shape their geographical boundaries.

Based on the findings of the empirical study, two main propositions are formulated. The first proposition refers to the negative relationship between the geographical distance to the district's actors and the use of organizational proximity as a means for reaching external knowledge sources. By contrast, the second proposition indicates the positive relationship between the geographical distance to the district's actors and the use of cognitive proximity as a means for reaching external knowledge sources.

As regards the firm strategic behaviors, it seems particularly crucial to exploit all the three dimensions of proximity, in order to guarantee openness and sustain innovativeness and competitiveness. Concerning policy implications, the local governments should address their actions to help and promote the openness of technology districts and the formation of technology clusters. With this aim, actions should be devoted also to sustaining single local firms that are part of a technology cluster but not of a technology district. These, in fact, by increasing their competitive position, may generate positive externalities in the local area, fostering the diffusion and sharing of knowledge in the area and, then, acting as knowledge gatekeepers for the whole area.

The paper extends the findings of previous works linking three proximity dimensions in a holistic framework that explains the different use of organizational and cognitive proximity to acquire knowledge, according to the geographical distance between organizations.

The paper aims to contribute to the Circular Economy debate from the Entrepreneurship Education perspective. Despite scholars' growing interest in both these research streams, scarce consideration is given to the comprehension of their mutual implications and meaning.

The paper is based on a cross-case analysis. It compares 16 higher education programmes launched by Universities in Europe aimed to create competences and skills for Circular Economy in students with different profiles. The analysis provides a critical view of the emerging trends for the entrepreneurship education skills and competencies needed for the emerging circular entrepreneurship paradigm.

The paper discusses the main trends of Entrepreneurship Education focused on Circular Economy debate at the European level: rationale and learning objectives (why); contents (what), target students and stakeholders (who) and the learning processes (how). Four thematic areas are identified as common patterns: circular economy business model, green supply chain management, technology entrepreneurship and innovation and public policies and institutional frameworks.

The paper sheds new light on a still under-researched area, suggesting several implications and avenues for future research in Circular Economy and Entrepreneurship Education. Limitations regard the need to analyse education programmes from a larger geographical area, to take into consideration interesting experiences in the rest of the world and to also collect quantitative data.

Practical implications arise for the development of learning initiatives for the Circular Economy: learning objectives and new thematic areas focused on circular, sustainable and innovative rethinking of the process for creating value in the incumbent companies; exploring meaning and benefits of collaborative approaches and participation in the circular economy innovation ecosystem and developing advanced models for soft-skills development in terms of leadership, motivational and creative skills.

The debate on CE can also be rooted in the paradigm of entrepreneurship as a core process to advance knowledge on valuable and sustainable innovation.

Are public officials held accountable for political scandals? Existing scholarship typically focuses on voters' response to scandals showing politicians are often punished at the polls for scandals. Specifically, they are more likely to be punished for the abuse of public office for personal gain than for scandals involving personal affairs. That said, not all politicians implicated in scandals seek reelection. Although difficult to observe, many politicians may be pushed out of office by their political party before they have an opportunity to stand for reelection – resigning or retiring before the next election. Others are appointed and consequently never stand for election. We collect a new dataset to understand how scandals affect politicians' careers and whether public officials are held accountable at other junctures. We trace the pathways of politicians implicated in scandals. We document the type and onset of scandals, individuals' reactions to scandals, and whether and when they leave office. Our novel data contribution provides rich descriptive statistics on corruption in the US Congress over time, with new insights into the conditions under which scandals end politicians' careers. The common patterns and significant differences revealed in these data suggest that the impact of scandals on public officials' careers may have less to do with the nature of the scandal or the specific actions undertaken by those implicated and may depend more on the actions of political parties.

In some settings, sharecropping is associated with large extended families, high fertility, and early age of marriage. These demographic practices are often considered to be labor strategies for working extensive share‐tenancies. Where agricultural production is primarily labor intensive, landlords can increase their income, within certain limits, by maximizing the number of adult workers. If landlords hold considerable power over their tenants, they may have a large influence on demographic practices. Although this relationship between sharecropping and some of these demographic practices is found throughout much of history in northern Italy, the evidence is less clear for fifteenth‐century Tuscany. Herlihy and Klapisch‐ Zuber's study of the Catasto of 1427, a set of tax declarations, found no relation between household structure and land tenure. Some of their work suggested that fertility was higher among sharecroppers, but this relationship was not specified in detail. They did not consider the relationship between land tenure and age of marriage. This paper reconsiders the relationship between land tenure, household structure, fertility, and age of marriage. To try to correct for problems with Herlihy and Klapisch‐Zuber's land tenure variable, their data were aggregated to the administrative unit of analysis. The aggregated data show that sharecropping in rural Tuscany in 1427 was associated with household extension, high fertility, and early age of marriage, although the magnitude of this relationship was not large. Possible reasons for this weak relationship are discussed.

The purpose of this paper is to understand why the neo‐Thomist natural law approach to social economics does not represent a trustworthy epistemological reference for the current social economists but, rather, definitively belongs to the past history of economics.

The approach ventures beyond an epistemological, methodological, and historical analysis of the causes that led to the rediscovery of Thomism, its golden age, and its abandonment. The theoretical and practical contents of the neo‐Thomist natural law approach to social economics are also carefully examined in order to identify its originality.

From this study, it clearly emerges that the modern conception of economics as a value‐free and context‐independent science is due to historical facts and ideological convictions and not to evidence in nature. This study also demonstrates that the disappearance of the neo‐Thomist natural law approach from the social economics debate is basically attributable to political, scholarly, and ecclesiastical factors and not to the loss of scientific reliability.

The treatment of the neo‐Thomist school is deployed in general terms with special reference to the principal scholars, Taparelli, Liberatore, and Leo XIII. In order to focus on the paper's aim, the author has not explored the particularity of each neo‐Thomist author's thought.

The practical desirability is to always render economists more aware of the fact that the societal and ethical context significantly mattered and continues to matter in the elaboration process of the economic theories.

The novelty consists of the attempt to explain the theoretical and practical reasons that historically and currently determine the sharp separation between the neo‐Thomist natural approach tradition and the social economics theory.

The purpose of this paper is to identify and examine the major forces that are changing the way biopharmaceutical medications are purchased, distributed, and sold throughout the supply chain. This will become important as healthcare reform moves forward, and logistics will be transformed in this industry.

Multiple interviews with key informants at each level of the value chain were combined with manifest text analysis from practitioner articles to derive key insights into the primary change drivers influencing the future of the biopharmaceutical supply chain.

The research discovered radical shifts in the structure of the biopharmaceutical supply chain. Future research into biopharmaceutical supply chain practices will need to explore three primary issues: How will supply chain member compensation influence the power of parties within the network? How will the role of supply chain intermediaries change the landscape of medication delivery to the end customer? What impact will the role of regulatory constraints on product pedigree and proliferation have on this network? The relationship between these forces is mediated by operations strategy concerning inventory policy, supply chain visibility, and desired service levels.

The research was based on multiple interviews with a convenience sample, as well as text analysis from practitioner articles. These findings are an initial step to guide future more in‐depth research for this dynamic and contextually rich supply chain environment that impacts consumers in every country in the world.

The paper adds insights into the pharmaceutical supply chain, examining this from multiple perspectives.

This paper analyses Roman fish tanks, which have functional elements that could be used to research on palaeo-sea-levels. Thus, the conditions of 37 installations in the Western Mediterranean basin are reviewed to identify those that have the best environmental and constructive conditions to be analyzed.

The methodology was largely based on the review of existing scientific bibliography dealing with sea-level variations from studies on historical constructions, existing historical documentation on Roman fish tanks on the Mediterranean coast, as well as the fieldwork carried out in fish tanks on the Mediterranean coasts.

The Roman coastal fish tanks located in the shoreline of the Western Mediterranean Sea have turned out to be an excellent indicator of sea-level changes. Nevertheless, current coastal retreat, erosion and storm surges are posing significant threats to their preservation, and they could be considered as a heritage at risk of disappearance. Moreover, variations in the tectonic behaviour of the different coastal sectors make it challenging to select these facilities as an indicator of the sea level.

The analysis of Late Holocene sea-level changes and palaeoenvironments from archaeological and biological evidences, although not without difficulties, is very convenient because it provides very precise data that cannot be obtained with other absolute dating methods. This approach is increasingly gaining popularity with researchers and is very innovative in its method of combining the results of several scientific disciplines.
