First-Order Languaging Dynamics and Second-Order Language: The Distributed Language View

2011

This article articulates some aspects of an emerging perspective shift on language: the distributed view. According to this view, languaging behavior and its organization is irreducible to the formal abstracta that have characterized the focus on a de Saussure-type system of formal regularities in mainstream linguistics over the past century. Language, in the distributed view, is a radically heterogeneous phenomenon that is spread across diverse spatiotemporal scales ranging from the neural to the cultural. It is not localizable on any one of them, but it involves complex interactions between phenomena on many different scales. A crucial distinction is thus presented and explained, viz. fir…

IEEE Access Special Section Editorial : Cloud and Big Data-Based Next-Generation Cognitive Radio Networks

2019

In cognitive radio networks (CRN), secondary users (SUs) are required to detect the presence of the licensed users, known as primary users (PUs), and to find spectrum holes for opportunistic spectrum access without causing harmful interference to PUs. However, due to complicated data processing, non-real-time information exchange and limited memory, SUs often suffer from imperfect sensing and unreliable spectrum access. Cloud computing can solve this problem by allowing the data to be stored and processed in a shared environment. Furthermore, the information from a massive number of SUs allows for more comprehensive information exchanges to assist the resource allocation and interference ma…

Stackelberg-Walras and Cournot-Walras equilibria in mixed markets: a comparison

2012

In this note, we compare two strategic general equilibrium concepts: the Stackelberg-Walras equilibrium and the Cournot-Walras equilibrium. We thus consider a market exchange economy embodying atoms and a continuum of traders. It is shown that, when the preferences of the small traders are represented by Cobb-Douglas utility functions, the Stackel-berg-Walras and the Cournot-Walras equilibria can coincide only if 1) the endowments and preferences of atoms are identical and 2) the elasticity of the followers’ best response functions are equal to zero in equilibrium.

The Power of Science Communication

2014

The study will investigate the concepts of science communication and its benefits. Being good communicators in general will help scientists to be better science communicators in order to: • help the public understand science as part of their real lives, • see not only the importance of the science and its source of pleasure and wonder, but also to be able to make decisions about it as citizens, policymakers, funders, etc. • help in educating citizenry, concerned about the threats facing our planet to better shape the direction of political and policy decisions, because how scientists communicate this information may have measurable conservation impacts on the future of our planet. More than…

The Logic of Gift: Inspiring behavior in organizations beyond the limits of duty and exchange

2016

[EN] Giving without the expectation of reward is difficult to understand in organizational contexts. In opposition to a logic based on self-interest or a sense of duty, a "logic of gift" has been proposed as a way to understand the phenomenon of free, unconditional giving. However, the rationale behind, and effects of, this logic have been under-explored. This paper responds by first clarifying the three logics of action¿the logic of exchange, the logic of duty, and the logic of gift¿and then explains how their balanced integration promises to enhance organizational life and outcomes. Having explicated the unique character and contributions of the logic of gift, the paper further suggests p…

PSD3 downregulation confers protection against fatty liver disease

2022

Fatty liver disease (FLD) is a growing health issue with burdening unmet clinical needs. FLD has a genetic component but, despite the common variants already identified, there is still a missing heritability component. Using a candidate gene approach, we identify a locus (rs71519934) at the Pleckstrin and Sec7 domain-containing 3 (PSD3) gene resulting in a leucine to threonine substitution at position 186 of the protein (L186T) that reduces susceptibility to the entire spectrum of FLD in individuals at risk. PSD3 downregulation by short interfering RNA reduces intracellular lipid content in primary human hepatocytes cultured in two and three dimensions, and in human and rodent hepatoma cell…

Conceptualizing Core Aspects on Circular Economy in Cities

2021

Currently, there are many different interpretations in the literature of what a circular economy is and how it functions. As cities are still facing challenges to become fully sustainable, the need for a comprehensive analysis of how the circular economy can be implemented in urban areas is increasing. This article aims at outlining circular cities by their key characteristics and to further explore and provide a framework for fostering circularity at the city level. In order to achieve this goal, we performed a systematic review and analyzed key papers published in the field of circular economy to determine how circular economy practices form circular cities. We discovered that cities play…

Trayectorias Económicas de las Regiones Españolas en un Escenario Post-crisis: Efectos de Vecindad, Especialización y Aglomeración.

2019

Over the last decade, the Spanish regions have undergone deep economic transformations that have gone hand in hand with changes in the production model. After the bursting of the housing bubble, growth has resumed through a recovery of the international competitiveness and a reorientation towards the foreign market. This new model has a clear territorial dimension visible in terms of unequal regional growth showing specific patterns and driving to a new territorial configuration. In order to define this nee configuration, we shall apply a spatial shift-share analysis to the Spanish regions for the periods 2008-13 (recession) and 2013-17 (recovery) aiming to split growth into its composing e…

The Dynamics of the Global Multinationals: Determinants of New Global Configurations and New Management Challenges

2018

During the last few decades, the complex interplay between (the process of) globalization and (the evolution of global) multinationals has radically changed both the architecture of the global economy and the characteristics of their main players – the global multinationals; new configurations have emerged, while new complexities have replaced them, in unprecedented (in terms of speed, breadth, and depth) manners, adding new valences to the challenges firms and their strategists are confronting nowadays. The aim of the paper is to identify (some of) the most significant shifts that have marked the dynamics of the global multinationals during the last two decades, in order to sketch the new …
