The New Economics of Positioning: places as knowledge platforms
No full textThe first chapter reviews the traditional innovation literature dealing with the relationship between market structures, technological and geographic space in promoting innovation. A large body of literature has studied which form of market was best suited to promote innovation, with mixed results leading to the emergence of the so-called innovation puzzle. The literature on the evolutionary economics of innovation has helped solve the puzzle through the identification of different innovation regimes based on technological characteristics. Thanks to the concept of relatedness, it is possible to consider these properties of knowledge in relation to place. In fact, the relationship between localized externalities and innovation is mediated by the degree of relatedness between the two, which constrains the flow of knowledge. From this perspective, a framework is proposed that jointly analyzes the characteristics of knowledge and spatial dynamics. This framework can help provide new insights into the innovation puzzle by helping to disentangle four different patterns of innovation in geographic and technological space based on the characteristics of knowledge and its relationship to the knowledge bases of places.The second chapter analyzes the relational proximity of Italian local labor systems through their positioning in input-output flows at different spatial scale. By applying the methodologies of Economic Complexity, backward (input-related) and forward (output-related) complexity are defined and used to study their contribution to productivity and GDP level of Italian local labor systems. In addition, using the Leontief's procedure, value added activated by final demand localized at different geographic scales is decomposed to measure the contribution of multilevel regional linkages and Global Value Chain participation. The results show that: i. forward complexity has a similar ability to explain variance in GDP per capita and productivity levels as the employment complexity; ii. Intra-regional, inter-regional and international capabilities appear to contribute to GDP per capita and productivity levels in ways specific to the degree of development; iii. both forward and backward complexity contribute to productivity growth, and more markedly to the growth of knowledge-intensive sectors, for SLLs with sufficient absorptive capacity. From a policy perspective, it follows that anchoring and positioning on multiscalar networks must be aligned with local absorptive capacities and degree of development.The third chapter analyzes how knowledge flows in the hierarchical and symbolic space of Italian provinces and regions through the analysis of the externalities of place narratives. This work proposes a new interpretation of place brand as a Multilevel Threshold Public Good (MTPG) produced by the interaction of narratives from different geographical levels. Using an original dataset of Google trends and tweets from Italian provinces and regions, we test the hypothesis that place branding has a multilevel structure. We further test the MTPG framework applied to place branding, showing that place branding is influenced by different geographic levels which can trigger a spillover in terms of attractiveness if they contribute to crossing a threshold point. The results confirm the presence of a provision point in place branding, showing that the proposed MTPG framework fits the phenomenon. This article contributes to the literature on place branding and brands by providing a new lens for interpreting the phenomenon, which may be useful in better understanding and measuring the interaction of branding strategies operating at different spatial scales
A multilevel threshold public good perspective on place branding: evidence from Italy

One-size-does-not-fit-all: The heterogeneous impact of BITs on regions participating in GPNs
No full textBilateral Investment Treaties (BITs) are vital for safeguarding and enhancing foreign investments, pivotal in Global Production Networks (GPNs). This study assesses the impact of BITs on GPNs driven by EU multinational enterprises, with a focus on regions hosting corporate headquarters due to their influence on the local economy. While considering the endogeneity of BITs and their diverse effects on GPN structures, our findings reveal a positive correlation between BITs and GPNs, notably stronger in less globally integrated regions. Additionally, the influence varies based on firms' network role (headquarters or subsidiaries) and the spatial distribution of headquarters. BITs stimulate GPNs in less internationalized regions but have minimal impact in headquarters-rich regions
On the Calogero-Moser space associated with dihedral groups
No full textInternational audienceUsing the geometry of the associated Calogero-Moser space, R. Rouquier and the author have attached to any finite complex reflection group several notions (Calogero-Moser left, right or two-sided cells, Calogero-Moser cellular characters), completing the notion of Calogero-Moser families defined by Gordon. If moreover is a Coxeter group, they conjectured that these notions coincide with the analogous notions defined using the Hecke algebra by Kazhdan and Lusztig (or Lusztig in the unequal parameters case). In the present paper, we aim to investigate these conjectures whenever is a dihedral group
Computational aspects of Calogero-Moser spaces
No full textInternational audienceWe present a series of algorithms for computing geometric and representationtheoretic invariants of Calogero-Moser spaces and rational Cherednik algebras associated with complex reflection groups. Especially, we are concerned with Calogero-Moser families (which correspond to the -fixed points of the Calogero-Moser space) and cellular characters (a proposed generalization by Rouquier and the first author of Lusztig's constructible characters based on a Galois covering of the Calogero-Moser space). To compute the former, we devised an algorithm for determining generators of the center of the rational Cherednik algebra (this algorithm has several further applications), and to compute the latter we developed an algorithmic approach to the construction of cellular characters via Gaudin operators. We have implemented all our algorithms in the Cherednik Algebra Magma Package (CHAMP) by the second author and used this to confirm open conjectures in several new cases. As an interesting application in birational geometry we are able to determine for many exceptional complex reflection groups the chamber decomposition of the movable cone of a Q-factorial terminalization (and thus the number of non-isomorphic relative minimal models) of the associated symplectic singularity

Classical hydrodynamics of Calogero-Sutherland models
No full textThe Calogero Sutherland model is system of particle moving on a line and interacting with long-range
forces. In this thesis we consider the classical case where the particles may or may not possess a spin degree of freedom. We demonstrate the intimate connection between the Calogero-Sutherland system and the Benjamin Ono equation. We then directly obtain a classical hydrodynamical limit of both the spineless and spinful Calogero system. The continuum limit of the spinless system is known to exhibit solition solutions.
We show numerically that the spinful system also exhibits localized solutions with the soliton property. This
is a strong evidence that the continuum spin-Calogero model is exactly integrable.Item withdrawn by Laura Spradlin ([email protected]) on 2014-07-21T22:07:40Z

The impact of Western beauty ideals on the lives of women and men: A sociocultural perspective
No full textAccording to a recent survey of 3,300 girls and women across 10 countries, 90 per cent of all women aged 15 to 64 worldwide want to change at least one aspect of their physical appearance, with body weight ranking the highest (Etcoff, Orbach, Scott, & D’Agostino, 2004). This finding suggests that women’s anxiety about their appearance is a global phenomenon, observed in every country studied from Saudi Arabia to the United States. Beyond body dissatisfaction, a stunning 67 per cent of all women aged 15 to 64 worldwide reported that they actually withdraw from life-engaging, life-sustaining activities due to feeling badly about their looks. These activities include giving an opinion, meeting friends, exercising, going to work, going to school, dating, and going to the doctor
Two new solvable dynamical systems of goldfish type
