The analysis of poverty in Italy. A fuzzy dynamic approach
2004
The commonly used criterion to sharply separate the poor from the non poor on the basis of a poverty threshold appears to be too severe in comparison with the nature of poverty. The latter is multidimensional in its components (domain) and continue in its states (codomain). Moreover an income-based poverty line allows for a remarkable number of spurious transitions below and over that line, which do not correspond to true variations in household’s standard of living. This study starts from the analysis of common (with crisp states) transition matrices; then a fuzzy multidimensional poverty indicator is built. In conclusion, fuzzy states transition matrices synthesize interpretative content …
The Determinants of Performance in China: A Study Focused on Cultural and Institutional Drivers in the Area of Shanghai
2015
We base our work on an historical study and on interviews of Chinese managers living in the area of Shanghai. We use the institutional theoretical stream in combination with the impact of national culture, considering that organizations and managers are influenced by cultural and institutional determinants. In a first part, we describe the theoretical background to the research and our method. Then, in a second part, we present the significant cultural and institutional features of China that enable us to justify several hypotheses about our topic. In a third part, we analyze twelve in-depth interviews, trying to answer our research question. Our basic research question focuses on what “Per…
Pre-treatment with high doses of cocaine decreases the reinforcing effects of cocaine in the conditioned place preference paradigm.
2012
The aim of the present study was to determine if pre-exposure to high doses of cocaine can subsequently alter the rewarding effects of this drug. Adult male mice received a pretreatment of physiological saline, or 12.5 or 25 mg/kg of cocaine (one injection a day for five days). After an interval of six days without injections, the rewarding effects of low doses of cocaine (0.5, 1 or 1.5 mg/kg) were evaluated in the conditioned place preference (CPP) paradigm. Doses of 1 and 1.5 mg/kg induced a clear CPP in animals pre-treated with saline but were ineffective in those pre-treated with 25 mg/kg of cocaine. Only the dose of 1.5 mg/kg induced CPP in mice pre-treated with 12.5 mg/kg of cocaine. …
Characterization of trophic links in an agrosystem : weed seed predation by carabid beetles
2012
Agroecology gives evidence of new perspectives in agriculture, and open doors for alternative weed management approaches through different regulation mechanisms. Seed predation is one of them, and the interest is growing to deepen knowledge, relative to this process. This Phd work aims (i) to describe weed seed predation, the dominant carabid predators and the available resource at a local scale in a common crop (winter wheat); (ii) to study predation profiles of main predators, and the pair-wise correlations between the biological components of the system; (iii) to bring new insights regarding potential regulation of weed communities, through seed predation by carabid beetles.

Adolescent Sexual and Emotional Development: The Role of Romantic Relationships
2015
Abstract The physiological processes occurring during adolescence, often so abrupt, threaten the permanence of the previously constructed sense of identity, questioning the patterns and representations that had governed the relations of the teenager with his body and with his relational systems. Although puberty is not only reduced to sexual transformations, definitions centered mainly on this aspect can be found in the literature. In fact, pubertal development is the acquisition disclosure index of adult reproductive capacity. Objective Explore the process of increasing involvement of the adolescent in an emotional and sexual relationship with a partner. Methodology: It will try to underst…
Models of e-testing
2017
Transdisciplinary interest and preoccupations regarding computer-assisted instruction have stirred our urge to perform a thorough study of the field and trends as well as to uphold certain approaches that have emerged in specialized scientific research. We have decided to focus our analysis primarily on the assessment process as a part of computer-assisted instruction; this in fact represents the major objective of our research, whereas the results of the experiments, performed in the context of the research projects undertaken, enabled us to set forth relevant conclusions about e-testing. Our computer-assisted assessment primarily includes tests with objective or semi-objective items, whic…
The business plan as a project: an evaluation of its predictive capability for business success
2012
Although there is extensive research aimed at identifying the main success factors for new ventures, efforts directed at evaluating the real effect of the existence and quality of a business plan on a firm's survival chances have been limited. This study attempts to fill this gap by analyzing to what extent the quality of a business plan, measured according to its economic, financial and organizational viability, constitutes a good predictor of business survival; and how other variables related to the characteristics of the entrepreneur and the business can affect the predictive capability of the model under consideration. Hypotheses are tested using data collected from 2142 service firms. …
The Role of Business Models in Developing Business Networks
2008
Business models have received a substantial amount of interest recently. Also, various research studies have discussed business models, especially in the context of a single company operating in mass markets. Unfortunately, these models often are not applicable for complex products or services that build on long-term knowledge about customer tastes, facilities, and skills. Especially on global markets, the asset specificity and vast geographical distances make it difficult for any single company to provide this kind of service cost-efficiently on a large scale. Instead, it calls for cooperation among multiple firms. Creation of a joint business model for a collaborative network is a necessa…
Stakeholder engagement toward value co-creation in the F&B packaging industry
2019
Purpose The purpose of this paper is to explore how a food and beverage packaging company manages internal and external stakeholders to achieve sustainable innovation outcomes, as well as to contribute to the spread of sustainability paths along the supply chain, on which it operates. Design/methodology/approach A case study approach was chosen and applied multiple methods of semi-structured interviews and a documentation review. Findings Results reveal a structured stakeholder relationship management, according to which the packaging company acts through a stakeholder engagement process to both acquire and share new knowledge to address stakeholder pressure. Co-creation models result in a…
Mines and quarries production: A driver analysis of withdrawals in Italy
2020
Abstract The growing demand for non-energy mineral resources has determined relevant withdrawals as well as import-export flows. This paper aims to disentangle the drivers of raw non-energy mineral resources extraction in Italy. Using a new dataset of raw resources extracted from mines and quarries in the 21 Italian regions (19 regions and 2 autonomous provinces of Trento and Bolzano) for the period 2013–2016, our empirical analysis confirms the relevance of mining and quarrying producer price index as well as the manufacturing and construction sectors as main drivers. In line with the Hotelling (1931)'s theory, a positive relationship between m&q mineral resources extraction intensity and …
