Exploring End-User Reactions to Variations in the Value Proposition of Value Services
2009
Value services are most often innovations where endusers have little or no experience from using the service. Designing business models for such services is a challenging task including the design of value propositions that are perceived and interpreted through end-users’ complex value assessments. This study presents the results from a study of end-user value assessments of value proposition variations for two value services – mobile VoIP and multi play services. The study suggests a method for investigating end-user reactions to value proposition variations and presents the effects of these variations on attribute perceptions and value drivers. The main contribution of the study is method…
The land values trend in Sicily (1992-2010)
2013
The present study aims to analyse the land market trend with particular reference to the main typologies of crop in Sicily (1992-2010). More specifically, after examining the trend in agricultural land average prices, both in current and constant terms, the dynamic formulation of Shift and Share Analysis (DSSA) was carried out, in order to check the growth gap between the average prices in the Sicilian provinces and the correspondent regional ones over the period, and trying to identify its causes also on the basis of the relationship between land values and the agro-food markets dynamics in the investigated period. The analysis of average land values shows a positive trend in current terms…
AREE DISMESSE ED ORTI URBANI: UN “VALORE SOCIALE COMPLESSO” NELLE CITTÀ Abandoned areas and urban gardens: a "complex social value" in the cities
2015
The contribution to the welfare of citizens that urban gardens can generate represents a "social use-value". The social value of horticulture in cities can be expressed by means of an appropriate set of indicators describing the produced values. The proposed work, which is the result of an interdisciplinary collaboration, highlights the potentiality of abandoned and degraded urban areas, and intends to outline a model for the assessment of the social value generated by the introduction of "urban gardens". The proposed model can be utilised for selecting the most suitable areas for the use in question, for monitoring the effects of policies for urban gardens on urban sustainability, and for …
Mucilage-Based and Calcium Ascorbate Edible Coatings Improve Postharvest Quality and Storability of Minimally Processed Cactus Pear Fruit Stored unde…
2022
The minimally processed fruit and vegetable industry showed rapid growth worldwide, primarily due to the increasing consumer need for ready-to-eat fresh products characterized by high nutritional, sensory and healthy value. The postharvest life of peeled cactus pear fruits is relatively short, due to the processing operations that affect fruit integrity and cause metabolic disfunctions, as well as pulp browning, microbial growth, loss of firmness, off-flavor development, and nutraceutical value loss. In this study, we investigated the effects of mucilage-based (OFI) and calcium ascorbate edible coating on minimally processed cactus pear summer-ripening fruit, cold stored under passive atmos…
High quality extra virgin olive oil from olives attacked by the olive fruit fly, Bactrocera oleae (Rossi) (Diptera Tephritidae): which is the tolerab…
2017
The infestation due to the olive fruit fly, Bactrocera oleae (Rossi), the key pest in most of world olive groves, has been monitored in six years, from 2004 to 2008 and in 2014, in eight coastal Sicilian olive groves consisting of ‘Cerasuola’ and ‘Nocellara del Belice’ cultivars. Infestation was recorded following the classical sampling method based on olive collection and dissection, in order to count live olive fruit fly instars (eggs, larvae and pupae) and exit holes. Four different infestation indexes, all of them calculated using data recorded at harvest, have been used to assess their relationship with the main three quality parameters of the olive oil obtained from the same olive sam…
Study of energetic properties of different tree organs in six Olea europaea L. cultivars
2021
AbstractPruning is an important horticultural practice for the management of olive orchards (Olea europaea L.) that generates a considerable amount of residues every year. Olive orchards are increasingly expanding beyond the Mediterranean Basin to new growing Countries (Australia, California, Argentina, Chile and Uruguay) and this will certainly lead to larger availability of pruning material. Currently, the interest in use of olive tree pruning residues for energy purposes is increasing but unfortunately, the information on the differences among organs of the tree, in terms of calorific value and ash content, is scarce. Another unknown aspect is the effect of cultivar vigour on dry matter …
Prospetto delle piante vascolari native di potenziale impiego negli interventi di fitodepurazione in Sicilia
2013
Checklist of the native vascular plants of potential use in phytoremediation in Sicily. A list of native vascular plants suitable for phytoremediation in Sicily is presented here. It includes 192 specific and intraspecific taxa, each provided with the relevantbiological form and subform, chorotype, and macrophyte classification. An index based on the aesthetic value of each taxon is also proposed.
Modulation of MMP-2 and MMP-9 in Churg-Strauss syndrome respiratory mucosa: potential monitoring parameters.
2014
Churg-Strauss (CSS) syndrome is rare and of unknown etiology. It is associated with vasculitis, blood eosinophilia and granulomatosis, and affects multiple organs and systems at various stages of the disease. Specific diagnostic and monitoring tests are not yet available. This study aims to assess the changes in MMP-2 and MMP-9 along with the histopathological alterations in two cases of CSS, as possible potential diagnostic and monitoring criteria. Two adult male patients were diagnosed with CSS in the otorhinolaryngology clinic in the University of Palermo, based on multiple clinical and histopathologic criteria. Biopsies of respiratory mucosa were taken after the consent of the patients…
Protecting entanglement by adjusting the velocities of moving qubits inside non-Markovian environments
2017
Efficient entanglement preservation in open quantum systems is a crucial scope towards a reliable exploitation of quantum resources. We address this issue by studying how two-qubit entanglement dynamically behaves when two atom qubits move inside two separated identical cavities. The moving qubits independently interact with their respective cavity. As a main general result, we find that under resonant qubit-cavity interaction the initial entanglement between two moving qubits remains closer to its initial value as time passes compared to the case of stationary qubits. In particular, we show that the initial entanglement can be strongly protected from decay by suitably adjusting the velocit…
L'invenzione nel quotidiano
2018
Michel de Certeau in the book "The Practice of Everyday Life" proposes the dimension of creativity as a widespread and multidirectional process, fueled by social dynamics and individual "tactics", able to evade and transform the sense and the objectives of knowledge and institutional powers. The text sets out some elements of the complex thought of the French scholar, useful to enrich the debate, the language and the visions of contemporary design. In fact nowadays the notions of "invention" and "everyday life" are recurrent in the design discourse, especially with reference to the emergence of a society founded on the diffusion of network technologies, data accumulation, artificial intelli…
