You Cannot Save Alone - Financial and Social Mobilization in Savings and Credit Groups
2007
Savings and credit groups are becoming increasingly popular, both as a cost-efficient alternative to mainstream microfinance and as a mean to mobilize people around individual and common challenges. Whether donors should promote and support Self Help Microfinance Groups that confine themselves to financial intermediation only - the specialist, or minimalist approach - or if they should support those pursuing a more integrated approach and incorporate a broader set of activities, is increasingly being debated. The study proposes a framework to better analyze and understand the different group-models, their advantages and disadvantages. Furthermore, the study outlines how social and financial…
Indigent consumers’ protection at the financial services market
2016
Opracowanie stanowi próbę odpowiedzi na pytanie, czy ochrona osób niezamożnych na rynku usług finansowych powinna być realizowana odrębnie w stosunku do powszechnie obowiązujących zasad oraz jakie elementy powinna obejmować ta ochrona? Ponadto – jakie podmioty powinny jej udzielać – czy te, które już istnieją na rynku, czy inne, nowe? Problem ochrony osób niezamożnych wynika stąd, że w dużej mierze osoby te są wykluczone z rynku podstawowego (mainstream market), objętego ochroną prawną. Część osób korzysta z oferty rynku alternatywnego, czy wręcz nieformalnego. Wydaje się więc, że dodatkowa ochrona osób niezamożnych powinna być ukierunkowana na te właśnie obszary rynku usług finansowych. Th…

A two-armed bandit collective for hierarchical examplar based mining of frequent itemsets with applications to intrusion detection
2014
Published version of a chapter in the book: Transactions on Computational Collective Intelligence XIV. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-662-44509-9_1 In this paper we address the above problem by posing frequent item-set mining as a collection of interrelated two-armed bandit problems. We seek to find itemsets that frequently appear as subsets in a stream of itemsets, with the frequency being constrained to support granularity requirements. Starting from a randomly or manually selected examplar itemset, a collective of Tsetlin automata based two-armed bandit players - one automaton for each item in the examplar - learns which items should be included in …
Development of Antioxidant Protein Extracts from Gilthead Sea Bream (Sparus aurata) Side Streams Assisted by Pressurized Liquid Extraction (PLE)
2021
The pressurized liquid extraction (PLE) technique was used, for the first time, to obtain protein extracts with antioxidant activity from side streams (muscle, heads, viscera, skin, and tailfins) of gilthead sea bream (Sparus aurata) in order to give added value to these underutilized matrices. Extraction conditions previously optimized for sea bass (Dicentrarchus labrax) side streams were applied. Protein recovery percentages were 22% (muscle), 33% (heads), 78% (viscera), 24% (skin), and 26% (tailfins), which represented an increase of 1.2–4.5-fold compared to control samples (extraction by stirring). The SDS-PAGE profiles revealed that PLE-assisted extraction influenced protein molecular …
DeCyMo: Decentralized Cyber-physical System for Monitoring and Controlling Industries and Homes
2018
The recent revolution of the Internet of Things has given the birth of a series of new technologies and cyber-physical systems to be used in industrial and home scenarios. Cyber- physical systems include physical and software components for providing smart monitoring and control with flexibility and adaptability to the operating context. The IoT paradigm enables the intertwined use of physical and software components through the interconnection of devices that exchange data with each other without direct human interaction in several fields, especially in industrial and home environments. We propose DeCyMo, a decentralized architecture that aims at solving common IoT issues and vulnerabiliti…
Economic Aspects of the Conjunctive Use of Ground and Surface Water
1989
Abstract The different structure of the costs of ground and surface water and the different and complementary characteristics of both kinds of resources make it possible to solve the specific needs of water quantity and quality more adequately and economically if both resources are used conjunctively. Higher discount rates favour the inclusion of elements involving lower initial investment and generally with higher groundwater components. Lower discount rates favour a higher participation of surface water. The external factors produced by groundwater pumping must be taken into consideration in any economic analysis. Examples of external factors are water level descents, surface water flow r…
Analysis of Hydrological and Landslide Hazards at Castellammare Del Golfo (Northern Sicily)
2014
Catastrophic floods or mass movements occur all too often owing to small streams overflowing their banks or to slope instabilities whose evolution has a more or less tragic impact on people and property; these events are the consequence of a poor understanding of the dynamics of geomorphological processes and of the laws governing them. This paper is focused on the case study of Castellammare del Golfo, a town in the province of Trapani. The study analysed the geological risk due to the geomorphology of the area and to the urban sprawl that it has experienced in the past decades. Geomorphological processes have a strategic role to play in spatial planning and management instruments and in t…
Experimental observations of Flow and Bed processes in a Large-amplitude Meandering Flume
2009
Meanders of large amplitude often exhibit asymmetric planform shape or subsidiary bends. The present work is aimed at improving on understanding of the morphodynamic phenomena affecting the bed evolution of large amplitude meandering channels. Attention is focused on the development of the steady point bar-pool configuration and of the superimposed large-scale migrating bed forms; of particular interest is the role of the changing channel curvature and bed topography variation on flow pattern. A series of experiments was carried out in a sine-generated large-amplitude meandering flume, for two values of width-to-depth ratio. Maps documenting the bed topography and the flow pattern along the…
Analyzing turbulence in gravel bed channels
2005
In this paper, the results of an experimental investigation of the turbulence intensity in gravel bed channels are described. The runs were carried out by measuring, with an acoustic Doppler velocimeter, the turbulence intensity profile along six verticals of a given cross section in a laboratory flume. The analysis of the measured intensity distributions has shown the existence of two different regions, above and below the tops of the roughness elements, in which different intensity profiles occur. Furthermore, the measured profiles have shown a maximum of the turbulence intensity that decreases for increasing values of the roughness height, confirming that the turbulence damping efficienc…
