The 43rd UID conference, held in Genova, takes up the theme of 'Dialogues' as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with 'others', which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, "dialogue" as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title 'translated' into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences.

This paper explores the properties of pre-test strategies in estimating a linear Cliff-Ord-type spatial model when the researcher is unsure about the nature of the spatial dependence. More specifically, the paper explores the finite sample properties of the pre-test estimators introduced in Florax et al. (2003), which are based on Lagrange Multiplier (LM) tests, within the context of a Monte Carlo study. The performance of those estimators is compared with that of the maximum likelihood (ML) estimator of the encompassing model. We find that, even in a very simple setting, the bias of the estimates generated by pre-testing strategies can be very large and the empirical size of tests can differ substantially from the nominal size. This is in contrast to the ML estimator. However, if the true data generating process corresponds to the spatial error or lag model the issues arising with the pre-test estimators seem to be lessened.

AbstractOne of the most debated issues in migration economics regards the effects of remittances in receiving countries. In this paper, we test whether the economic complexity of a country is relevant for understanding the impact of remittances on new firms' birth. We find evidence that the impact of real per capita remittances on new firms' creation is inversely mediated by economic complexity. More (less) complex economies generate opportunities to found new firms which need high (low) funding. Since economic complexity is positively correlated with economic development, remittances are more likely to facilitate the establishment of new firms in less developed economies rather than in more advanced ones. We also examine the link between remittances and new firm creation for Africa, Asia, Europe, and Latin America and the Caribbean countries, finding very heterogeneous patterns. Hence, policy implications aiming at attracting remittances to create new firms should respond to the challenges posed by specific countries and be tailored to their peculiar needs. Countries of origin should build institutions and facilitate the creation of networks to bridge the diaspora abroad with their home country to increase awareness of new business opportunities. Policy initiatives could spur investment in the formal economy by making regulations less stringent, discouraging the use of remittances for consumption purposes, reducing informality, improving competition, reducing remittance transfer costs, and giving incentives to new firms created through remittances.

Recent academic debates concerning the WPS agenda have highlighted the existence of several cracks undermining the conceptualisation as well as the operationalisation and implementation of the principles and actions stemming from the WPS framework. After proposing to consider the WPS Agenda as a norm lab and recognising the urgency to repair its conceptual cracks, this article critically analyses two main conceptual weaknesses limiting the emancipatory potential of the Agenda, namely the conceptualisation of identity and agency that it reflects and projects, arguing that the former reveals a stereotypical and ambiguous formulation, while the latter is thin and unfit for sustaining a transformative political project. The article discusses insights from the discussion on epistemic (in)justice, which originated from the work of Miranda Fricker, arguing that they are valuable heuristic resources for developing a WPS conceptual framework able to escape the essentialist trap, identifying the injustices done to women and men as discriminated and marginalised subjects in their capacity as knowers and active contributors to the dialogues concerning the planning and deployment of measures for conflict and post-conflict management.
