La partecipazione ad un business ecosystem: implicazioni per la nozione di successo
2020
L’obiettivo del capitolo è offrire un’introduzione alla letteratura sugli ecosistemi aziendali e discutere critica-mente la tematica del successo e della misurazione delle performance del business ecosystem e degli attori che vi partecipano. A tale scopo, il capitolo è strutturato come segue. Il paragrafo 2 focalizza l’attenzione sulla definizione di business ecosystem. I paragrafi 3, 4 e 5 spiegano, rispettivamente, perché nasce un business ecosystem, chi sono gli attori e quali sono le strutture sottese agli ecosistemi aziendali. Il paragrafo 6 discute la misurazione delle performance del business ecosystem focalizzando l’attenzione sui seguenti aspetti: (a) indicatori di performance a li…
New evidence on accelerator performance based on funding and location
2020
Seed accelerators (SAs) appear as a more advanced version of business incubators. These for-profit organizations in exchange of equity, help setting new start-ups by providing mentoring and funding during its first months. Due to their emergent nature, the impact and expectations of SAs remains largely unknown. Therefore, the purpose of this study is to throw new light on this field by empirically assessing for the first time the performance and prospects of these organizations through a survey of 116 SAs.,A model based on the Business Incubators literature is built with four categories covering size, location, age and profitability variables, leading to two hypotheses to be tested empirica…
Executive remuneration determinants: New evidence from meta-analysis
2019
This meta-analysis takes stock of 121 C.E.O. pay studies published between 1998 and 2018 with the objective of identifying the main drivers of C.E.O. pay from a global perspective and contributing to the agency vs managerial debate on this ground. The meta-results disclose a positive C.E.O. pay–performance correlation (the highest correlation coefficient corresponds to Earnings per share with a 34%) as the agency theory prescribes and the governance policies promote. However, firm size still predominates as the main driver of C.E.O. pay (correlation coefficient is around 44%) according to managerial premises. Moreover, our results reconcile both approaches because results of the meta-regres…

Organizational Virtues, Performance and Job Satisfaction. Differences according individual and organizational factors in Argentinean employees
2017
El presente trabajo se basa en las propuestas de la Psicología Organizacional Positiva (POP) que intenta integrar a la mirada clásica de estudios organizacionales –que se focaliza en analizar condiciones negativas–, una perspectiva que visualice variables positivas que contribuyan a obtener resultados óptimos (Cameron & Spreitzer, 2012). Se planteó como objetivo analizar si existen diferencias en las virtudes nivel organizacional (Apoyo y respeto, Significado e inspiración, Perdón) según variables individuales (e.g. personal a cargo) y organizacionales (e.g. tamaño y tipo de empresa). Asimismo, se buscó establecer si existe relación entre dichas virtudes y medidas resultado (performance org…
Search for neutral heavy leptons produced in Z decays
1997
Weak isosinglet Neutral Heavy Leptons ($\nu_m$) have been searched for using data collected by the DELPHI detector corresponding to $3.3\times 10^{6}$ hadronic~Z$^{0}$ decays at LEP1. Four separate searches have been performed, for short-lived $\nu_m$ production giving monojet or acollinear jet topologies, and for long-lived $\nu_m$ giving detectable secondary vertices or calorimeter clusters. No indication of the existence of these particles has been found, leading to an upper limit for the branching ratio $BR($Z$^0\rightarrow \nu_m \overline{\nu})$ of about $1.3\times10^{-6}$ at 95\% confidence level for $\nu_m$ masses between 3.5 and 50 GeV/$c^2$. Outside this range the limit weakens rap…
TCP Performance in Mobile Ad hoc Networks
2013
International audience; In this paper, we present a survey of TCP (Transmission Control Protocol) protocol for better performance in the MANET (Mobile Ad Hoc Network). After a short presentation of the main features of TCP, we give the most important problems from which TCP suffer in MANET. We present after that some approaches proposed in the literature in order to improve its performance. Our paper contains also a performance evaluation of TCP NewReno and TCP Vegas transport protocols under AODV and DSR routing protocols. The simulations are conducted under varying conditions of number of TCP connections, number of nodes and mobility.
L’analisi delle politiche di riduzione dei cesarei attraverso il dynamic performance management: La valutazione del percorso nascita in un’azienda sa…
2018
Da tre decenni l'Organizzazione Mondiale della Sanità considera appropriata una percentuale di cesarei tra il l 0-1 5%. Tuttavia, molti Paesi tuttora si trovano a fronteggiare valori molto più elevati e le politiche adottate dai decisori pubblici spesso mostrano di essere poco efficaci. Il presente lavoro prende avvio dall'analisi del percorso nascita introdotto in Sicilia e propone il ricorso all'approccio del Dynamic Performance Management per investigare le cause sottostanti l'andamento dei parti cesarei. Lo studio ha consentito di costruire un modello di System Dynamics, successivamente personalizzato con i dati di un'azienda sanitaria. L'analisi dei risultati delle simulazioni evidenzi…
Framing Caesarean Section Reduction Policies Through a Dynamic Performance Management Approach: A Maternity Pathway Case-Based Analysis
2017
The World Health Organization since the last three decades strongly encourages countries to reduce the caesarean section (CS) rate down to 10–15%. However, this goal nowadays appears still far from its achievement. Public decision-makers are indeed struggling to design and implement effective policies to reduce the CS rate. The literature provides a wide range of factors causing a change in the CS rate, such as the patient clinical profile and the healthcare service quality provided. Maternity pathway (MP) is considered a mean through which to standardize the cares and to reduce CSs. This study investigates the MP recently introduced in Sicilian local health authorities. Based on such an an…
