Towards hardware acceleration of neuroevolution for multimedia processing applications on mobile devices

This paper addresses the problem of accelerating large artificial neural networks (ANN), whose topology and weights can evolve via the use of a genetic algorithm. The proposed digital hardware architecture is capable of processing any evolved network topology, whilst at the same time providing a good trade off between throughput, area and power consumption. The latter is vital for a longer battery life on mobile devices. The architecture uses multiple parallel arithmetic units in each processing element (PE). Memory partitioning and data caching are used to minimise the effects of PE pipeline stalling. A first order minimax polynomial approximation scheme, tuned via a genetic algorithm, is used for the activation function generator. Efficient arithmetic circuitry, which leverages modified Booth recoding, column compressors and carry save adders, is adopted throughout the design

Exploring a New Form of Horizontal Coordination to Improve Economic Sustainability of the Soft Wheat Chain in the Northwest of Italy

The Italian legal framework for the agricultural sector has recently introduced a new form of contract, the \u201cnetwork contract\u201d. The aim of this study is to verify if the use of this new contract would be appropriate to facilitate the adoption and diffusion of sustainable innovation of an Italian agri-food chain and to strengthen the agricultural role with dealing food processing companies. We focus on Piedmont, an Italian region where a soft wheat supply chain is in continuing evolution but is still very fragmented; indeed the two Producers Organization and one Consortium specialized in grain storage and trade only work around 30% of the grain produced annually. Following the framework of transaction cost we carried out a survey using semi-structured interviews as a qualitative analysis tool to gather the opinions of the primary operators in the Piedmont soft wheat supply chain. Initial results suggest that there is still an unsatisfactory horizontal coordination in the supply chain and that the network contract still seems to be little known and appreciated. However operators of the production stage of the chain consider the goals of improving the quality of the wheat and the economic and environmental sustainability very important but they think it would be difficult to achieve them simultaneously

Precarious Irregular Migrants and Their Sharing Economies: A Spectrum of Transactional Laboring Experiences

There is growing interest in the sharing economy as a different way of living in neoliberal capitalist societies, but this discussion is frequently heavily classed and the ethos generally rests on excess capacity of goods and services. This article intervenes in this emerging body of writing to argue that it is equally important to explore the types of sharing and exchange that are survival-compelled among those with precarious livelihoods. Precarious migrants are a group facing significant livelihood pressures, and we are concerned here with a particular category of insecure migrants: irregular migrants including refused asylum seekers in the United Kingdom. Such migrants are especially shaped by their sociolegal status, and without rights to work or welfare they are susceptible to exploitation in their survival-oriented laboring. Existing literature from labor geographies and the subdisciplinary area of unfree and forced labor has not generally focused on the experiences of these migrants as house guests in domestic realms, nor has it thoroughly explored their transactional labor. As such, this article argues that the moral economies of gifting and sharing within such labor create and reproduce particular social structures, cultural norms, and relationships that position people along a spectrum of freedom and exploitation

Rural World, Migration, and Agriculture in Mediterranean EU: An Introduction

AbstractThis book investigates the dynamics that are reshaping human and natural landscapes in the European agrarian world, with a specific focus on Mediterranean Europe. We focus here on more marginal rural settings, where the potential for agricultural intensification is structurally limited. These areas in particular have suffered from the geographical and socio-economic polarization of development patterns and have paid a relevant burden to the recent crisis

The Study of Irregular Migration

AbstractThe study of irregular migration as a specific social phenomenon took off during the 70s in the US. Since then, the academic interest has continually grown and spread, first to Europe and, in the last years, to other regions worldwide. This interest can certainly be related to the increasing attention paid to the study of migrations more in general (Castles & Miller, 1993). The trend can be linked to those broad and complex social and economic changes, often subsumed under the concept of globalization. The specific focus on irregular migration, though gaining momentum throughout the 1980s, reached preeminent attention in the 1990s. On both sides of the Atlantic, the explosion of the so-called "migration crisis" (Zolberg & Benda, 2001) and the emergence of irregular migration as a widespread social fact raised the attention of public opinion and academics alike. Moreover, in recent years, what seemed at first to be an issue concerning only the high-income regions of the planet, now involves also medium and low-income ones, making irregular migration a truly global structural phenomenon (Cvajner & Sciortino, 2010a; Düvell, 2006)
