Nuovi paradigmi per le aree interne. Il caso del Territorio Sicano.
2015
Il contributo descrive i primi esiti della ricerca sulle opportunità di sviluppo del territorio Sicano, condotta nell’ambito del Laboratorio di Sviluppo Locale del Polo Universitario di Ricerca di Bivona e Santo Stefano Quisquina per l’energia, l’ambiente e le risorse del territorio. La ricerca indaga un’area composta da 24 comuni, le cui risorse e coalizioni territoriali già attive possono indirizzare forme di sviluppo verso la ricapitalizzazione del territorio, il recupero del valore della ruralità e della capacità di costruire qualità dell’ambiente e dell’abitare, reti corte di produzione e consumo e offerta turistica. Il contributo, oltre a definire la metodologia di indagine applicata,…
Dissesto idrogeologico e urban eco-planning. Una proposta per contrastare la fragilità del territorio urbano di Agrigento
2017
I più recenti fenomeni naturali calamitosi che hanno interessato l’Italia si sono verificati in concomitanza di anomali cambiamenti climatici la cui causa è il riscaldamento globale. Il V rapporto dell’IPCC 2014 afferma che il global warming è determinato dalle attività antropiche. A livello mondiale, l’Italia è realmente minacciato dalla “desertificazione” per circa 1/5 del territorio nazionale, soprattutto al Sud: la Sicilia con una percentuale del 70% risulta, in tal senso, la regione più a rischio (“Convegno sulla siccità”, CNR per Expo 2015). Con l’innalzamento delle temperature si ha una diminuzione delle precipitazioni e un aumento dell’intensità delle stesse con pericolo di dissesto…
Zvanu centra klienta das
2016
Ikdienas darbs nav iedomājas bez saziņas ar saviem biznesa klientiem, tāpēc attīstoties tehnoloģijām attīstās arī veids, kā tiek glabāti klientu dati, padarot tos ērti lasāmus un viegli pieejamus. Zvanu centra klienta datu apstrādes sistēma piedāvā vienotu un pārskatāmu risinājumu uzņēmumiem, kam ir savi privātie zvanu centri, glabāt klientu datus vienotā sistēmā un ļaut ar tiem darboties zvanu centra operatoriem. Sistēma nodrošina lietotāju un tiesību pārvaldības funkcionalitāti sistēmā, sistēmas lietotāju darbību reģistrāciju, sistēmas kopēju klasifikatoru izveidi un pielietojumu, katram reģionam piesaistītu aģentu, dažādu kampaņu izveidi, klientu kontaktinformācijas glabāšanu, kā arī ats…
Der Völkerfrühling von 1848/1849 – revolutionäre Gefahr oder republikanischer Durchbruch? Ästhetisch-historische Bilder
2022
The aim of this article is to present the revolutionary events of 1848/1849 in German states from the point of view of Joseph von Eichendorff and Theodor Opitz, which are based on their refl ections, experiences and reactions to this political and breakthrough coup. Eichendorff and Opitz present two different views on the events of the Spring of Nations. These two intellectuals and writers are linked by the last letter from Eichendorff to Theodor Opitz as well as the ideal of freedom, which became their life motto.
User Grouping and Power Allocation in NOMA Systems: A Reinforcement Learning-Based Solution
2020
In this paper, we present a pioneering solution to the problem of user grouping and power allocation in Non-Orthogonal Multiple Access (NOMA) systems. There are two fundamentally salient and difficult issues associated with NOMA systems. The first involves the task of grouping users together into the pre-specified time slots. The subsequent second phase augments this with the solution of determining how much power should be allocated to the respective users. We resolve this with the first reported Reinforcement Learning (RL)-based solution, which attempts to solve the partitioning phase of this issue. In particular, we invoke the Object Migration Automata (OMA) and one of its variants to re…
Symmetry as an Intrinsically Dynamic Feature
2010
Symmetry is one of the most prominent spatial relations perceived by humans, and has a relevant role in attentive mechanisms regarding both visual and auditory systems. The aim of this paper is to establish symmetry, among the likes of motion, depth or range, as a dynamic feature in artificial vision. This is achieved in the first instance by assessing symmetry estimation by means of algorithms, putting emphasis on erosion and multi- resolution approaches, and confronting two ensuing problems: the isolation of objects from the context, and the pertinence (or lack thereof) of some salient points, such as the centre of mass. Next a geometric model is illustrated and detailed, and the problem …
Intra-Party Heterogeneity in Policy Preferences and Its Effect on Issue Salience: Evidence from the Comparative Candidates Survey
2016
Quantitative research on the positions of political parties and party competition regularly invokes the assumption that parties are unitary actors with homogenous policy preferences. Drawing on Comparative Candidates Survey (CCS) data from 28 elections in 21 developed democracies, we show that candidates often hold quite heterogeneous issue positions and that the extent of this heterogeneity varies significantly across parties and, most interestingly, even within parties across different issue dimensions. In an effort to explore the implications of such intra-party heterogeneity for party strategy and competition, we argue that intra-party heterogeneity and issue salience go together, becau…
Properties and constraints of cheating-immune secret sharing schemes
2006
AbstractA secret sharing scheme is a cryptographic protocol by means of which a dealer shares a secret among a set of participants in such a way that it can be subsequently reconstructed by certain qualified subsets. The setting we consider is the following: in a first phase, the dealer gives in a secure way a piece of information, called a share, to each participant. Then, participants belonging to a qualified subset send in a secure way their shares to a trusted party, referred to as a combiner, who computes the secret and sends it back to the participants.Cheating-immune secret sharing schemes are secret sharing schemes in the above setting where dishonest participants, during the recons…
Il lavoro etero-organizzato prima e dopo il caso Foodora Italia.
2019
l contributo ripropone la discussione sull’esegesi della fattispecie disciplinata dall’art. 1 comma 2 del d. lgs. n. 81 del 2015 (nel testo anteriore alla riforma del 2019) trattata dall’autore nei Colloqui Giuridici sul Lavoro del 2015 (a cura) di Antonio Vallebona per il Massimario di Giurisprudenza del Lavoro. Lo studio rigettava la tesi che il lavoro organizzato dal committente fosse la terza fattispecie e anzi con riferimento delle condizioni di applicazione dimostrava la necessità di una lettura includente. La conclusione era che la nuova disciplina aveva natura antifraudolenta e determinava un allargamento (relativo) dell’area della subordinazione conseguente alla riduzione del cam…
Tiešsaistes Klientu Segmentācija, Izmantojot Klasterizācijas Metodes
2021
Bakalaura darba mērķis ir izpētīt tiešsaistes klientu segmentāciju, lai tā palīdzētu pieņemt loģiskus lēmumus par efektīvu mārketinga un reklāmas resursu izmantošanu. Darbā tika izmantotas divas klasterizācijas metodes: K-Medoīdu (K-Medoids) klasterizācija, un K-Prototipu (K-Prototypes) klasterizācija. Metožu izvēle tiek pamatota ar pētītā uzdevuma raksturojumu. Darba gaitā tiek aprakstīti gan abu metožu teorētiskie aspekti, gan metodes tiek pielietotas praktiski (izmantojot programmu R) konkrēta uzdevuma risināšanai. Tika veikta iegūto rezultātu analīze un salīdzināšana. Bakalaura darbā tika arī paskaidrota klientu segmentācijas nozīme veiksmīgam uzņēmumam, kā arī tika aprakstīts interneta…
