SAM multipliers and subsystems: Structural analysis of the Basilicata’s agri-food sector

Local agri-food products are conceived as a form of cultural capital, representing potentially fruitful resources for rural development. Italy and its regions offer a rich and diverse agricultural and food heritage that has led to the creation of numerous quality agri-food systems. Despite their ability to absorb disturbances and maintain their functions, it is important to develop economic models targeted to analyse the relationships among the components of food systems, in order to identify their strengths and weaknesses and drive the implementation of sectoral policies. In view of the new Rural Development Programme (2014-2020), the aim of this work is to analyse the structure of the Basilicata’s agri-food system using a multi-sector model based on a two-region SAM, specifically developed for Basilicata, an Italian region charac-terised by a highly specialised agri-food sector. Results show that the availability of a highly disaggregate multi-sector model of the regional economy may be a valuable supporting tool to design regional policies for innovation and for the development of rural areas, laying the foundation for further analysis

Towards Sustainable and Inclusive Communities: An Integrated Approach to Assess Sustainability in Rural Areas

Sustainable development is a priority in EU rural development strategies. Due to the multidimensionality of the sustainability issue, this paper presents a Spatial Decision Support System to assess territorial sustainability and help decision- makers in rural planning process. Four globally valid sustainability dimensions were considered (long-term ecological sustainability, satisfaction of basic human needs, promotion of intragenerational and intergenerational equity), measured by a set of socio-cultural-political-environmental indicators by using the Mazziotta and Pareto method. The results of the S-DSS, implemented and verified in Basilicata region (southern Italy), provide the maps of sustainability values for each dimension at municipalities level, showing the usefulness of the tool to identify and monitor rural areas that require priority interventions and resources, in order to foster sustainable rural development

The hidden value of nontimber forest products: income contribution of the Basilicata wild truffle

The Basilicata region (South of Italy) is land of truffles where the gastronomic, economic and cultural awareness has developed for this non-timber forest product only in the past decade. Little is known about truffle production and its social, economic and environmental implications. In this article we investigate the Basilicata truffle sector by devoting particular attention to the truffle hunters who gather the truffles from the forests. The data for the analysis were collected through a survey with the aim of describing the gathering activity (people involved, specie and quantities collected, etc.) and assessing its significance as a source of income. Results show that truffles can provide local communities with earning opportunities. However, the truffle sector needs to be protected and enhanced

Understanding the Role of Nature in Urban-Rural Linkages: Identifying the Potential Role of Rural Nature-Based Attractive Clusters That Serve Human Well-Being

Rural areas provide unique amenities for recreational purposes which are highly appreciated by urban inhabitants. This generates an important but often hidden relationship between the urban and the rural. The aim of our study is first to provide empirical evidence for this linkage and then to identify for Italy, at the municipal level, those rural areas which actually function as nature-based attractive clusters. We used the data coming from a participatory webGIS survey that asked 1632 Italian respondents to mark attractive nature related places locally, regionally, nationally and world-wide to explain quantitatively and qualitatively the relationship between urban and rural. From the survey, indicators were developed to rank the nature-based attractive clusters. Our results pointed out a major (almost double) flow from urban to rural for natural amenities, which increased with the spatial level at which attractive nature areas were marked. This analysis allowed for the identification rural clusters of Italian municipalities that form nodal points for nature-based urban well-being; shedding light on an often neglected urban-rural relationship. The method is applicable in other countries and may stimulate better planning and management strategies for improving rural areas, taking an urban-rural perspective

Young People Are Not All the Same! The Theory of Planned Behaviour Applied to Food Waste Behaviour across Young Italian Generations

To reach the SDG 12.3 target, understanding food waste behaviour (FWB) is fundamental, especially among young people. As future generations of parents, leaders, and citizens, they might potentially solve food sustainability issues and other matters arising from food waste. In such a context, this study extends the theory of planned behaviour (TPB) by including personal norms and environmental concern to explain and to predict the FWB of young Italians who belong to Generation Y and Generation Z. The theoretical model was empirically tested by administering a questionnaire to 322 Italian young people and by applying two distinct PLS-SEM models for Generation Y and Generation Z. Our results support not only the main relationship suggested by the TPB model with respect to FWB but also that, in affecting it, personal norms and environmental concern play different roles according to the generations. Understanding the mechanisms through which personal norms and environmental concern translate into reducing food waste is crucial to defining interventions aimed at changing youth behaviour. It could represent a relevant step towards preventing food waste and promoting sustainable management of food chains

Identification of LIMK2 as a therapeutic target in castration resistant prostate cancer

This study identified LIMK2 kinase as a disease-specific target in castration resistant prostate cancer (CRPC) pathogenesis, which is upregulated in response to androgen deprivation therapy, the current standard of treatment for prostate cancer. Surgical castration increases LIMK2 expression in mouse prostates due to increased hypoxia. Similarly, human clinical specimens showed highest LIMK2 levels in CRPC tissues compared to other stages, while minimal LIMK2 was observed in normal prostates. Most notably, inducible knockdown of LIMK2 fully reverses CRPC tumorigenesis in castrated mice, underscoring its potential as a clinical target for CRPC. We also identified TWIST1 as a direct substrate of LIMK2, which uncovered the molecular mechanism of LIMK2-induced malignancy. TWIST1 is strongly associated with CRPC initiation, progression and poor prognosis. LIMK2 increases TWIST1 mRNA levels upon hypoxia; and stabilizes TWIST1 by direct phosphorylation. TWIST1 also stabilizes LIMK2 by inhibiting its ubiquitylation. Phosphorylation-dead TWIST1 acts as dominant negative and fully prevents EMT and tumor formation in vivo, thereby highlighting the significance of LIMK2-TWIST1 signaling axis in CRPC. As LIMK2 null mice are viable, targeting LIMK2 should have minimal collateral toxicity, thereby improving the overall survival of CRPC patients

Mapping the recreational value of coppices’ management systems in Tuscany

In recent decades the growing interest in forested areas has led to a higher level of appreciation and consideration regarding the various benefits and services provided by forests. Despite this, when it comes to acknowledging their economic value and their capacity to produce income, the production of timber seems to be the main or even the only function that is considered. However, by adopting a sustainable forest management approach, the value related to non-market forest functions could also be considered. The present paper aims to quantify the potential income related to the recreational value of coppice forest by considering three different management systems: traditional coppice, active conversion to high forest and the natural evolution of forest. In order to do so, a contingent valuation method was used, and 248 forest users were surveyed in the region of Tuscany, Italy. The surveys included a revised price-list method, and the results obtained showed the existence of willingness to pay (WTP) for the maintenance of forests. Users showed a strong preference for conversion to high forest, while natural evolution was the least preferred management option. People’s perception on this matter was also assessed based on their specific location, by georeferencing all of the respondents’ answers: considering this, it was observed that belonging to a municipality located in or close to the mountains (i.e., mountain and natural municipalities) influenced the users’ WTP to maintain natural evolution

Interpretation of Unresolved Mossbauer Spectra in Compounds of I~~~*

Recebido em 2 de Setembro de 1971 The Mossbauer-effect absorption spectra of the rare earth tri-iodides, Lal,, Gdl, and Erl, show evidence of unresolved quadrupole splitting. We propose that the electric field gradient (EFG) responsible for the interaction can be associated with a partially filled p hole (hd in the 5s25p6 eiectronic configuration of I-. The quadrupole coupling parameters and isomer shifts are determined from a least squares fitting of the data using as initial estimates the C[" NQR data for equivalent rare earth tri-chlorides. For Lal, , Gdl, and Erl, these ar
