Which social program supports sustainable grass-root finance? Machine-learning evidence
2019
Resources for development are used efficiently when social programs help to promote at the same time the sustainability of grass-root financial associations at the bottom of the pyramid. This study applies machine-learning to a worldwide database of grass-root associations in order to identify which social programs are good predictors of financial returns in the groups. The results indicate that education, income-generating activities and health programs are the most frequent programs provided by development agencies. Business training is not the most frequent intervention applied to grass-root associations, but it is in fact the most important social program to encourage financial sustaina…
An Overview on European Union Sustainable Competitiveness
2014
Abstract The last few years have emphasized a continuing concern of many institutions, nations, companies for sustainable development. The recent literature brings into attention the concept of sustainable competitiveness beyond sustainable development. The main idea of sustainable competitiveness is reflected by the searching of a model that could balance economic prosperity, environmental issues and social sustainability. In this context, is shaping the sustainability-adjusted global competitiveness index that take into consideration two new dimensions – environmental and social. Practically, the triple bottom line concept will be extrapolated from the microeconomic level to the macroecon…
An innovative model for a sustainability report in no-profit organizations
2016
After a review of the literature, the research aims to build a sustainability report for NPOs through a set of economic, environmental and social indicators based on best international practice. Then the report will be applied to a voluntary service centre (CSV) which, in terms of function and organisation, over a wide range, contains all the social and economic environmental variables to be monitored in any NPOs. The findings appear to suggest an innovative model of sustainability report for NPOs with a significant set of indicators that offer a new disclosure of the activity carried on by the organisation. The work is tested only on a limited number of NPOs which can be extended in the fu…
Sustainability Triple Bottom Line Management Enhancement for Municipal Level: Integrated Governance Environment Dimension
2015
To ensure sustainable development of a municipality, it is necessary to improve the potential for development of measures of environmental management balancing the economic, social and environmental dimensions. A lot of municipalities having successfully established goals and objectives, tend to sustainable management, evaluate the quality of local governance, including preparation of documents of the environmental policy and setting the administrative tasks and priorities related to assumptions of sustainable development, systemic evaluation, interdisciplinary approach, and implementation of governance as a comprehensive collaborative management. This review article describes the main comp…
Arguments in Favor of Moving to a Sustainable Business Model in the Apiary Industry
2017
Abstract Today’s society faces major challenges in meeting future global food demands and solving biodiversity loss, and it quickly needs to find ways in addressing these issues. The places to look for solutions come from the economic sectors that employ the most powerful pressure on these issues such as agriculture. Apiculture, as a branch of agriculture is being more and more recognized as sustaining human life and contributing to sustainability. However, the sector records a progressive decline of honey bees. Therefore, a rapid restructuring needs to take place in agricultural markets, in general, as well as in apiary agribusinesses. Although important, technological progress is insuffic…
Pannello precompresso di vetromattoni assemblati a secco per la realizzazione di involucri traslucidi
2012
L’invenzione riguarda la realizzazione di un pannello di vetromattoni montati “a secco” -da impiegare per la realizzazione di involucri edilizi traslucidi anche nel caso di edifici alti- che è in grado di rispondere adeguatamente alle sollecitazioni orizzontali (quali quelle dovute a vento e sisma) grazie all’applicazione della tecnica della precompressione mondirezionale. Per offrire una risposta ai limiti imposti dalla tecnica di assemblaggio tradizionale dei vetromattoni (“ad umido”), l’applicazione della precompressione consente, infatti, di dare ai pannelli preassemblati “a secco” una rigidezza adeguata anche in direzione normale al loro piano di posa, sfruttando le buone caratteristic…
On parsing optimality for dictionary-based text compression—the Zip case
2013
Dictionary-based compression schemes are the most commonly used data compression schemes since they appeared in the foundational paper of Ziv and Lempel in 1977, and generally referred to as LZ77. Their work is the base of Zip, gZip, 7-Zip and many other compression software utilities. Some of these compression schemes use variants of the greedy approach to parse the text into dictionary phrases; others have left the greedy approach to improve the compression ratio. Recently, two bit-optimal parsing algorithms have been presented filling the gap between theory and best practice. We present a survey on the parsing problem for dictionary-based text compression, identifying noticeable results …
Dictionary-symbolwise flexible parsing
2012
AbstractLinear-time optimal parsing algorithms are rare in the dictionary-based branch of the data compression theory. A recent result is the Flexible Parsing algorithm of Matias and Sahinalp (1999) that works when the dictionary is prefix closed and the encoding of dictionary pointers has a constant cost. We present the Dictionary-Symbolwise Flexible Parsing algorithm that is optimal for prefix-closed dictionaries and any symbolwise compressor under some natural hypothesis. In the case of LZ78-like algorithms with variable costs and any, linear as usual, symbolwise compressor we show how to implement our parsing algorithm in linear time. In the case of LZ77-like dictionaries and any symbol…
Multiple SIP strategies and bottom-up adorning in logic query optimization
1990
Preprocessing methods called “readorning” and “bottom-up adorning” are introduced as means of enlarging the application domain of magic sets and related query optimization strategies for logic databases. Readorning tries to make possible the simultaneous use of multiple sideways information passing (sip) strategies defined for a rule, thus yielding an optimization effect that may not be achieved by any particular choice of sip strategies. Bottom-up adorning is used to make magic sets applicable to cases in which potential optimizations can be derived from bindings coming upwards from rule bodies to rule heads in bottom-up evaluation. These include the cases in which we know that some base r…
Measurement of thett¯production cross section inpp¯collisions ats=1.96 TeVusing soft electronb-tagging
2010
The authors present a measurement of the t{bar t} production cross section using events with one charged lepton and jets from p{bar p} collisions at a center-of-mass energy of 1.96 TeV. A b-tagging algorithm based on the probability of displaced tracks coming from the event interaction vertex is applied to identify b quarks from top decay. Using 318 pb{sup -1} of data collected with the CDF II detector, they measure the t{bar t} production cross section in events with at least one restrictive (tight) b-tagged jet and obtain 8.9{sub -1.0}{sup +1.0}(stat.){sub -1.0}{sup +1.1}(syst.) pb. The cross section value assumes a top quark mass of m{sub t} is presented in the paper. This result is cons…
