Up-to-Date Supply Chain Management: The Coordinated (S, R) Order-Up-to
2011
This paper presents the mathematical derivation of a new generation of the most largely used periodic review policy in supply chain: the coordinated (S, R) replenishment rule. We first derive the classical order-up-to model and then we modify it to generate the coordinated decision policy equations. We run a numerical simulation on a serial supply chain model to show differences in the two policies. We conclude on the managerial implications related to coordinated replenishment.
Environmental taxation, information precision, and information sharing
2022
We analyze how environmental taxes should be optimally levied when the regulators and firms face costs uncertainties in a Stackelberg-Cournot game. We allow linear-quadratic payoffs functions coupled with an affine information structure encompassing common and private information with noisy signals. In the first period, the regulator chooses the intensity of emissions taxes in order to reduce externalities. In the second period, facing industry-related and firm-specific shocks, firms compete in the marketplace as Cournot rivals and choose outputs. We show that, given costs uncertainties with non-uniform quality of signals across firms, the regulator sets differentiated tax policy. We also e…
L'ecomuseo del grano e del pane: un percorso progettuale centrato sul design
2018
La festa di S. Giuseppe, oltre che un’importante e sentita ricorrenza religiosa, è a Salemi soprattutto la “festa dei pani”; bellissime realizzazioni di alto artigianato artistico, la cui sapienza si tramanda nelle famiglie e nelle associazioni di donne che per mesi lavorano alla produzione dell’enorme quantità delle piccole e grandi forme di pane, per rivestire le costruzioni votive che accolgono il rito della cena. Nasce quindi l’idea di proporre un “Ecomuseo del grano e del pane” nel Collegio dei Gesuiti, valorizzando e riaprendo al pubblico uno spazio di grande interesse storico-architettonico. Nell’ambito della consolidata collaborazione del Comune di Salemi con il Dipartimento di Arch…
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…
What drives the disintegration of the loan origination value chain in the banking business
2015
Purpose - The purpose of this paper is to analyze the vertical disintegration of the bank loan origination value chain. This paper conducts a study on the credit information market from the perspective of the bank's decision to vertically disintegrate the loan origination value chain. The main aim is to identify the relevant drivers of the decision to vertically disintegrate the credit assessment phase in the lending business.Design/methodology/approach - Transaction cost economics and information asymmetry are the typical perspectives of analysis of the vertical scope of business value chains.Findings - This paper argues that in order to capture the drivers underlying the dynamic evolution…
Wpływ traktatu lizbońskiego na regulacje imigracyjne UE ze szczególnym uwzględnieniem zasady solidarności i sprawiedliwego podziału odpowiedzialności…
2018
Analysis of the influence of the Treaty of Lisbon on the EU immigration reguiations with particular attention to the principle of solidarity and fair sharing of responsibility between Member States indicates that the Treaty of Lisbon extensively reformed these reguiations. Its premise and mechanisms should be assessed as justified. However, they give a lot ofleeway for interpretation and need to be supplemented with EU secondary law. Unfortunately, States are primarily driven by their interest when applying these rules which leads to their nonproductiveness. The recent migration crisis explicitly proves this. The reason for the above can be found, among other things, in attachment to classi…
Secure, dependable and publicly verifiable distributed data storage in unattended wireless sensor networks
2010
Published version of an article from the journal : Science in China, Series F: Information Sciences. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s11432-010-0096-7 In unattended wireless sensor networks (UWSNs), sensed data are stored locally or at designated nodes and further accessed by authorized collectors on demand. This paradigm is motivated by certain scenarios where historical or digest data (e.g., average temperature in a day), instead of real-time data, are of interest. The data are not instantly forwarded to a central sink upon sensing, thereby saving communication energy for transmission. Such a paradigm can also improve data survivability by m…
What Are the Latest Fake News in Romanian Politics? An Automated Analysis Based on BERT Language Models
2021
Social media and news outlets facilitate information sharing, while the Web is flooded by information posted online on a daily basis. However, content may be differently transmitted from case to case, based on the authors’ intentions and vocabulary, to the extent that it generates completely opposite points of view. As such, fake news have become a global phenomenon, and recent events highlight a high impact of distorted or fake information, especially on the political side, when candidates’ discourses include tendentious statements that require careful validation before completely trusting the source. This paper proposes an automated analysis of political statements in Romanian by applying…
The Euro Area Crisis; Need for a Supranational Fiscal Risk Sharing Mechanism?
2013
The aim of this paper is to assess the effectiveness of risk sharing mechanisms in the euro area and whether a supranational fiscal risk sharing mechanism could insure countries against very severe downturns. Using an unbalanced panel of 15 euro area countries over the period 1979â2010, the results of the paper show that: (i) the effectiveness of risk sharing mechanisms in the euro area is significantly lower than in existing federations (such as the U.S. and Germany) and (ii) it falls sharply in severe downturns just when it is needed most; (iii) a supranational fiscal stabilization mechanism, financed by a relatively small contribution, would be able to fully insure euro area countries …
Tailorable Representation of Security Control Catalog on Semantic Wiki
2018
Selection of security controls to be implemented is an essential part of the information security management process in an organization. There exist a number of readily available information security management system standards, including control catalogs, that could be tailored by the organizations to meet their security objectives. Still, it has been noted that many organizations tend to lack even the implementation of the fundamental security controls. At the same time, semantic wikis have become popular collaboration and information sharing platforms that have proven their strength as an effective way to distribute domain-specific information within an organization. This paper evaluates…
