Tumor Board and Molecular Tumor Board

Specialized expertise and cooperation between different professional figures are increasingly needed for the management of cancer patients. Tumor boards (TB) can address this issue by gathering together different healthcare providers to periodically discuss challenging cases.
Energy efficient resource allocation in heterogeneous software defined network: A reverse combinatorial auction approach
2015
In this paper, resource allocation for energy effi- ciency in heterogeneous Software Defined Network (SDN) with multiple network service providers (NSPs) is studied. The considered problem is modeled as a reverse combinatorial auction game, which takes different quality of service (QoS) requirements into account. The heterogeneous network selection associated with power allocation problem is optimized by maximizing the energy efficiency of data transmission. By exploiting the properties of fractional programming, the resulting non-convex Winner Determination Problem (WDP) is transformed into an equivalent subtractive convex optimization problem. The proposed reverse combinatorial auction ga…
Recenti tendenze in tema di responsabilità degli intermediari di Internet nella tradizione giuridica occidentale
2019
Il saggio prende in esame il dibattito circa la necessità di modificare gli attuali regimi di irresponsabilità degli intermediari della rete, dibattito in corso nelle esperienze statunitense ed unitaria europea. Con riferimento all’esperienza statunitense, non è chiaro, infatti, se il ricorso sempre più frequente alla procedura di notice and take down sia sintomo del successo del sistema di notice based liability, congegnato dal legislatore federale nel 1998 o sia, al contrario, espressione del suo fallimento. In tale ottica, al fine di verificare la possibilità di transitare da un sistema di notice and take down ad un sistema di notice and stay down, il saggio prende in esame le recenti in…
How do online communities matter? Comparison between active and non-active participants in an online behavioral weight loss program
2016
This paper contributes to the discussion on the potential of different social media platforms in health behavior change programs. More specifically, it compares the outcomes of participation in different online community platforms in an online behavioral weight loss program. Results show that active participants on online community platforms perceive their service experience more positively, follow instructions more precisely, have a more positive perception of achieving their goals, and also feel that they receive more social support than do those who do not actively participate in online community channels, although no differences were found related to weight loss itself. Furthermore, int…
Customer satisfaction in B2B cloud services
2013
Tutkimuksen tavoitteena on kirjallisuuskatsauksen kautta esitellä B2B-pilvipalveluiden asiakastyytyväisyyteen vaikuttavia seikkoja, ja kuinka näitä seikkoja tulisi ottaa huomioon asiakastyytyväisyyden parantamisessa. Tässä tutkimuksessa verkkopohjaiseen liiketoimintaan liittyvää asiakastyytyväisyyden tutkimusta käytettiin pohjana etsiessä asiakastyytyväisyyteen vaikuttavia seikkoja pilvipalveluissa. Tutkimuksessa vertaillaan asiakastyytyväisyyteen vaikuttavia seikkoja vertailemalla tyytyväisyyteen vaikuttavia seikkoja verkkopohjaisen liiketoiminnan, yritysliiketoiminnan (B2B) ja kolmen asiakastyytyväisyyden ja palvelun laadun mallin (American Customer Satisfaction Index, SERVQUAL and SaaS-Q…
Äitien palvelutyytyväisyyden rakentuminen ja yhteistyökokemukset varhaiskasvatuksessa
2021
Artikkelissa tutkitaan äitien tyytyväisyyttä noin yksivuotiaan lapsensa varhaiskasvatuspalveluun tarkastelemalla palvelutyytyväisyyden ulottuvuuksia. Lisäksi tutkitaan äitien ja varhaiskasvatuksen henkilökunnan välisen yhteistyön sekä palveluntarjoajan (yksityinen vs. kunnallinen) yhteyttä äitien palvelutyytyväisyyteen. Lopuksi tarkastellaan, eroaako yhteistyön yhteys palvelutyytyväisyyteen palveluntarjoajan mukaan. Tutkimusaineisto koostuu CHILDCARE-hankkeen kyselytutkimukseen osallistuneiden varhaiskasvatuksessa olevien yksivuotiaiden äitien vastauksista (N = 549). Analyysimenetelminä käytettiin eksploratiivista faktorianalyysia sekä hierarkkista lineaarista regressioanalyysiä. Äitien tyy…
Opaque Distribution Channels for Competing Service Providers: Posted Price vs. Name-Your-Own-Price Mechanisms
2014
Opaque selling has been widely adopted by service providers in the travel industry to sell off leftover capacity under stochastic demand. We consider a two-stage model to study the impact of different selling mechanisms, posted price (PP) versus name-your-own-price (NYOP), of an opaque reseller on competing service providers who face forward-looking customers. We find that in this environment, providers prefer that the opaque reseller uses a posted price instead of a bidding model. This is because the ability to set retail prices is critical for extracting surplus from customers who wait to purchase from the reseller. Such surplus extraction enables providers to set high prices for advance…
Osservazioni sul Digital Services Act: responsabilità e gestione del rischio nella prestazione di servizi intermediari
2022
Il saggio esamina la nuova regolazione europea, in corso di approvazione, che definisce responsabilità e obbligazioni del prestatore di servizi della società digitale, e in particolare delle piattaforme digitali, modificando la disciplina della direttiva 2000/31/CE. La nuova disciplina genera un doppio livello di regolazione, un sistema bipolare costituito dalla convivenza della regola di esenzione di responsabilità per il prestatore con un sistema di obblighi crescenti soggettivamente differenziati, al fine di aumentare la capacità della legislazione europea di incrementare la tutela consumeristica al tempo della “rivoluzione digitale”.

PSD2 ja sen vaikutukset verkkomaksamisen tietoturvaan ja liiketoimintamalleihin
2016
Web payments have created a whole industry around them in the last decade where sensitive data is moved around and where security is one of the key concepts. On top of internal facilities, members of the EU are regulated by EU directives of which the second will be taken to legislation by the start of year 2017. It forces the banks to open interfaces that allow third parties to use web shop customers banking credentials in order to initiate payments. Second directive on payment services brings up a set of web security hazards that have yet to be studied. In this thesis a literature review is made on web payment security. I will also study the second directive on payment services and its eff…
