Il cibo come mezzo per una convivenza ostipitale. Gli equilibri fragili del cotto e del crudo fra migranti e popolazione autoctona in un mercato di P…
2021
In questo articolo le ricercatrici riesaminano il concetto di ostipilità (Derrida, 2000) alla luce della cultura materiale, del cibo e delle pratiche alimentari connesse, per analizzare i collegamenti tra cibo, appartenenza e commensalità. L’osservazione partecipante e le interviste semi-strutturate di questa ricerca hanno permesso di segnare i confini del mercato di Ballarò, di individuare le tipologie di attività commerciale, fondate sul “cotto” e/o sul “crudo”, che contraddistinguono le diverse aree di mercato, come pure le forme di “convivenza armata” in atto fra autoctoni e migranti. Se il cibo cotto è ospitale a determinate condizioni, il cibo crudo ha maggiori probabilità di stabilir…
Applying systems thinking concepts in the analysis of knowledge sharing on WeChat.
2019
This research is intended to theoretically investigate and analyse the characteristics of WeChat and its effect on knowledge sharing through a systems thinking approach. As one of the most popular mobile social application in China, WeChat has social attributes and the functions of multimedia interaction platform and has been gradually used in knowledge management practice. On one hand, comparing with virtual communities of practice, WeChat provides a more open and individual environment which break free the shackles of workplace relations. On the other hand, as a user-operated media and instant messaging software, WeChat has dramatically different structure with academic social network sit…
You are not alone – Social sharing as a necessary addition to the Embracing factor
2017
AbstractI argue that the Embracing factor cannot be adequately conceptualized without taking into account the regulatory power of the social sharing of emotions. Humans tend to share their negative emotions with close others, and they benefit from it. I outline how this mechanism works in art reception by regulating and transforming negative emotions into positive experiences.
The Serial Property and Restricted Balanced Contributions in discrete cost sharing problems
2006
We show that the Serial Poperty and Restricted Balanced Contributions characterize the subsidy-free serial cost sharing method (Moulin (1995)) in discrete cost allocation problems.
Designing and pricing guarantee options in defined contribution pension plans
2015
Abstract The shift from defined benefit (DB) to defined contribution (DC) is pervasive among pension funds, due to demographic changes and macroeconomic pressures. In DB all risks are borne by the provider, while in plain vanilla DC all risks are borne by the beneficiary. However, for DC to provide income security some kind of guarantee is required. A minimum guarantee clause can be modeled as a put option written on some underlying reference portfolio and we develop a discrete model that selects the reference portfolio to minimize the cost of a guarantee. While the relation DB–DC is typically viewed as a binary one, the model shows how to price a wide range of guarantees creating a continu…
Information Sharing and Channel Construction of Supply Chain under Asymmetric Demand Information
2014
Information sharing and marketing channel building have become an important problem of supply chain management theory and practice. The research of information sharing focused on traditional channel of supply chain between upstream and downstream enterprises; however, the research ignores the behavior of information sharing with potential entrants and composite structure characteristics about traditional marketing channel with the direct channel. This paper uses the model to research the effects brought about sharing demand information with potential entrants and building marketing channel, which reveals information sharing and channel building mechanism in the supply chain. The study found…
Qualitative and Quantitative Study on Videotaped Data for Fire Emergency Response
2016
During search and rescue (SAR) operations, information plays a significant role in empowering the emergency response personnel at various levels. But, understanding the information which is being shared between/among emergency personnel is necessary to improve current coordination systems. However, such systems can help the first responders to gain/increase their situational awareness and coordination. Moreover, there is still the lack of automatic and intelligent tools that can contribute to structure, categorize, and visualize the communicated content that occur during SAR operations. Therefore, in this paper, we present the concept of such analysis by using the qualitative methodology an…
An analysis of ego network communities and temporal a affinity for online social networks
2017
The wide diffusion of Online Social Networks (OSNs) presents several advantages, like the definition of simple tools for information sharing and spreading. However, OSNs present also some drawbacks, one of the most important one is the problem of privacy disclosures. Distributed Online Social Networks (DOSNs), which decentralize the control of the social network, have been recently proposed to overcome these issues. The decentralization of the control has issued several challenges, one of the main ones is guaranteeing data availability without relying on a central server. To define users’ data allocation strategies, the knowledge of the structure of the ego network and of the user’ temporal…
Information behaviour of the millennial generation: a scoping review of medical residents and their use of social media.
2018
Background Medical residents can offer ideas for new information services, as most of them are 'digital natives', although reviews of the use of social media in health care settings do not provide data on their information behaviour. Objective A scoping review aimed at providing a research map for the information behaviour of medical residents and their use of social media, listing the aspects of the information behaviour studied and the theories and methods used. Methods A search was carried out in pubmed, embase, cinahl and lisa in April of 2018, with the results limited to the period from 2010 onwards. Results Thirty-nine relevant articles from 38 different studies were identified. The p…
Capacity constrained supply chains: a simulation study
2008
This paper explores the relationship between constrained capacity and supply chain performance. Six capacity constraint levels are studied under different inventory policies and information sharing strategies. The results suggest that an increment of production capacity, used in industry as local approach to manage increasing incoming orders, does not necessarily imply an improvement in customer service. In presence of information distortions, the strategy of augmenting production capacity can lead to satisfy at a higher cost an over-estimated market demand. The collaborative practices provide bullwhip effect dampening and inventory stability, and increase the ability of the structure to av…
