R&D alliance partner attributes and innovation performance: a fuzzy set qualitative comparative analysis
No full textPurpose: Drawing upon the importance of research and development (R&D) alliances in driving firm innovation performance, extant research has analyzed individually the impact of R&D alliance partner attributes on firm innovation performance. Despite such analyzes, research has generally underestimated the configurations of partner attributes leading to firm innovation performance. This research gap is interesting to explore, as firms involved in R&D alliances usually face a combination of partner attributes. Moreover, gaining a better understanding of how R&D partner attributes tie into configurations is an issue that is attracting particular interest in coopetition research and alliance literature. This paper aims to obtain a better knowledge of this underrated, but important, aspect of alliances by exploring what configurations of R&D alliance partner attributes lead firms involved in R&D alliances to achieve high innovation performance. To tackle this question, first, this study reviews the extant literature on R&D alliances by relying on the knowledge-based view of alliances to identify the most impactful partner attributes on firms’ innovation performance. This paper then applies a fuzzy set qualitative comparative analysis (fsQCA) to explore the configurations of R&D alliance partner attributes that lead firms involved in R&D alliances to achieve high innovation performance. Design/methodology/approach: This study selects 27 R&D alliances formed worldwide in the telecom industry. This paper explores the multiple configurations of partner attributes of these alliances by conducting a fsQCA. Findings: The findings of the fsQCA show that the two alternate configurations of partner attributes guided the firms involved in these alliances to achieve high innovation performance: a configuration with extensive partner technological relatedness and coopetition, but no experience; and a configuration with extensive partner experience and competition, but no technological relatedness. Research limitations/implications: The research highlights the importance of how partner attributes (i.e. partner technological relatedness, partner competitive overlap, partner experience and partner relative size) tie, with regard to the firms’ access to external knowledge and consequently to their willingness to achieve high innovation performance. Moreover, this paper reveals the beneficial effect of competition on the innovation performance of the firms involved in R&D alliances when some of the other knowledge-based partner attributes are considered. Despite these insights for alliance and coopetition literature, some limitations are to be noted. First, some of the partners’ attributes considered could be further disentangled into sub-partner attributes. Second, other indicators might be used to measure firms’ innovation performance. Third, as anticipated this study applies fsQCA to explore the combinatory effects of partner attributes in the specific context of R&D alliances in the telecom industry worldwide and in a specific time window. This condition may question the extensibility of the results to other industries and times. Practical implications: This study also bears two interesting implications for alliance managers. First, the paper suggests that R&D alliance managers need to be aware that potential alliance partners have multiple attributes leading to firm innovation performance. In this regard, partner competitive overlap is particularly important for gaining a better understanding of firm innovation performance. When looking for strategic partners, managers should try to ally with highly competitive enterprises so as to access their more innovative knowledge. Second, the results also highlight that this beneficial effect of coopetition in R&D alliances can be amplified in two ways. On the one hand, when the partners involved in the alliance have not yet developed experience in forming alliances. Partners without previous experience supply ideal stimuli to unlock more knowledge in the alliance because new approaches to access and develop knowledge in the alliance could be explored. On the other hand, this paper detects the situation when the allied partners are developing technologies and products in different areas. When partnering with firms coming from different technological areas, the knowledge diversity that can be leveraged in the alliances could drive alliance managers to generate synergies and economies of scope within the coopetitive alliance. Originality/value: Extant research has analyzed individually the impact of R&D alliance partner attributes on firm innovation performance but has concurrently underestimated the configurations of partner attributes leading to firm innovation performance. Therefore, this paper differs from previous studies, as it provides an understanding of the specific configurations of R&D alliance partner attributes leading firms involved in R&D alliances to achieve high innovation performance

An FPGA-based instrument for the estimation of R, L, and C parameters under nonsinusoidal conditions
No full textIt is well know that the most of today electric and electronic devices frequently work with non sinusoidal waveforms, then, all the passive R, L, and C component, sited in these circuits, are involved with non sinusoidal stimuli. Because of its intrinsic non-linearity, real resistors, inductors, capacitors and so on show behaviors very different from those expected in sinusoidal environment. Consequently, a problem of reliable assessment of these components in presence of non sinusoidal environments arises. This problem is even more critical in applications such as the creation of hybrid filters, control circuits based on patterns of sensing elements, circuits of digital protection in power systems, where the design and control of electrical and electronic circuits depend on the correct modeling of the R, L and C components. In previous researches authors proposed a suitable measurement method for the estimation of R, L and C parameters of passive components in non sinusoidal conditions. This paper deals with the realization of a FPGA-based measurement instrument able to continuously update the estimated values of the considered components. The instrument realization passes through an optimized implementation of the previous-proposed measurement method aimed in minimizing the hardware resources and the computational burden, and increase the measurement rate. After a preliminary tuning of the measurement method, carried out in simulation environment, the hardware and the software architectures of the realized measurement instruments together with the measurement strategy are described, and experimentally characterize

Primo Festival Internazionale del Teatro per le Diverse Abilità" organizzato dal Centro Studi per l’integrazione lavorativa dei disabili della ASL 3 “Genovese” in collaborazione con l’associazione culturale “la Milonga” e il Laboratorio Teatrale Integrato Tuttinscena, con il sostegno della Provincia di Genova e della Regione Liguria, il patrocinio dell'Università degli Studi di Genova, e la collaborazione di otto teatri genovesi. Responsabile: Maria Paola Ferrigno; Progettazione artistica: Cristina Valenti; Coordinamento artistico: Sandro Baldacci. In conclusione, il convegno "D.verse Abilità e Teatro", occasione che ha consentito a studiosi, attori, registi e scrittori di interrogarsi sulle nuove frontiere del teatro come strumento di integrazione e sul peculiare apporto che artisti “diversamente abili” possono dare alla rappresentazione artistica. Il cartellone ha ospitato alcune fra le più importanti compagnie di teatro integrato, e di compagnie composte da attori disabili, che operano in Italia e in Europa. Il Festival si è aperto con il musical “l’Anima Buona del Pianeta Sezuan” del Laboratorio Tuttinscena: trenta ragazzi, di cui una buona parte portatori di handicap, provenienti da dieci scuole genovesi, per la regia di M. Pirovano e M. Bonomi. A seguire: “Microphobia” e “The Human Suite”, due coreografie della CandoCo Dance Company di Londra, una compagnia di danza contemporanea formata da danzatori disabili e normodotati, leader nella formazione e nell’educazione alla danza integrata; “La Sirena di Rodari” del Laboratorio Teatrale Integrato Piero Gabrielli di Roma, per la regia di R. Gandini: tredici “ex” del laboratorio in uno spettacolo che ha dato vita alla prima Compagnia Italiana Integrata di Teatro Ragazzi; “Esopo Opera Rock”, musical per la regia di S. Baldacci, frutto di un laboratorio integrato che ha coinvolto i centri diurni della Città di Imperia, il DAMS di Genova e operatori socio sanitari; “No Exit”, regia di A. Viganò, della compagnia francese Oiseau Mouche, finanziata dallo stato e composta da attori professionisti portatori di handicap; “Ritratti” di Lenz Rifrazioni di Parma per la regia di M.F. Maestri: cinque ritratti del mito occidentale resi con eccezionale forza rappresentativa delle attrici diversamente abili ; “Filottete H” di Maccabeteatro per la regia di E. Toma: ispirato a Sofocle, lo spettacolo, con attori portatori di handicap, tratteggia la difficoltà di accettare l’idea di non essere perfetti.
A conclusione del ciclo di rappresentazioni, il convegno dal titolo "D.verse Abilità e Teatro". Interventi di E. Buonaccorsi (Università di Genova ), M.P. Ferrigno (Centro Studi della ASL 3 “Genovese”), G. Oliva (Università Cattolica di Milano), C. Valenti (Università di Bologna), A. Celestini (attore e regista), R. Frati (Teatro dell’Oppresso di Parigi), T. Scarpa (scrittore), D. Segre (regista). In chiusura: “A proposito di sentimenti”, mediometraggio di D. Segre. Il Festival si è concluso con la performance “Emplacement Reservé”, che Rui Frati ha rappresentato con i suoi attori e con il coinvolgimento diretto del pubblico presente. Le disavventure di una madre “speciale” a causa delle circostanze che coinvolgono sua figlia disabile. Un modo dinamico e vitale affinché il dibattito e l’atto teatrale siano un unico corpo
50+ years of R&D Management: a retrospective synthesis and new research trajectories
No full textIn 2020, R&D Management celebrated 50 years of publication. The present study honors that milestone by conducting a retrospective examination of the research conducted in the journal over time and reflects on its rich history to look forward in the R&D management field. Using bibliometric techniques, we provide a comprehensive analysis of the journal’s most prominent topics and themes, as well as its most prolific authors, institutions, and countries.
The findings indicate that R&D Management has increased its productivity and reputation as measured by the number of published articles and citations per year and expanded its
international reach from the initial European-dominated
author base. We complement this analysis by performing an in-depth systematic literature review of the most frequently cited
papers –annually and of all time –to disentangle the themes and concepts that prominently shaped the progress of the discipline itself. The results suggest that R&D Management has
progressively widened its field of investigation from an intra-organizational perspective (1970–1992) to an inter-organizational
view (1992–2006) and then to an extra-organizational outlook (2006–2018).
Finally, based on this history and viewing the contributions from 2019 onwards, we identify an emerging set of research trajectories that we expect will pave the way for the future impact of R&D Management and the field at large
Innovating and transforming during COVID-19: insights from Italian firms
No full textDuring the COVID-19 pandemic, a huge number of firms had to stop their activities due to the lockdown situation that has been decided in most countries. However, to contribute to the many emergencies caused by the pandemic through purpose-led actions, many of those firms have reacted with innovative projects and changes in their manufacturing activities. In this paper, we address why and how these efforts have been implemented and how the situation of these firms evolved after the peak of the health crisis. Drawing on the literature about the purpose and R&D/innovation management concerning health emergency, we develop a conceptual framework to understand how different types of purpose-led actions (i.e., short term and/or long term) and different R&D management strategies (i.e., exploitation or exploration of R&D, innovation, and manufacturing competencies) can characterize firms’ rapid response for the benefit of the community in the fight against COVID-19, for example through the provision of medical equipment or other products and services. We validate the framework using the cases of 21 Italian firms which have taken very fast actions during the peak of the COVID-19 emergency
Measurement of Passive R, L, and C Components Under Nonsinusoidal Conditions: The Solution of Some Case Studies
No full textThis paper deals with the measurement of the R, L, and C parameters of passive components in nonsinusoidal conditions. Since these components usually work with voltage and current waveforms that are different from sinusoidal ones, nonsinusoidal characterization has to be made. The importance of nonsinusoidal characterization of passive components is highlighted through the analysis of two case studies: (1) the influence of distorted waveforms on the line impedance stabilizer network (LISN) passive component behaviors and (2) the influence of voltage and current harmonics on hybrid filter responses. In this paper, the authors propose and describe a measurement method based on linear system identification and model parameter estimation techniques. Then, the two case studies are analyzed and described with the help of some test results
Real-Time Measurement of Time Variant R, L and C Components in Non Sinusoidal Conditions
No full textThe authors are involved in realizing an innovative measurement instrument for the real-time estimation of Resistance (R), Inductance (L) and Capacitance (C) parameters that models real electrical passive components in non sinusoidal environment. This instrument aims to cover the lack of reference instruments and measurement methods for the assessment of electrical passive components in non sinusoidal conditions. In previous papers the authors proposed a measured method implemented in a FPGA platform. In this paper a further step is proposed optimizing the dynamic behavior of the instrument with respect to fast time-variant passive components. The novelty manly consists on the improved signal processing procedure that implements a “forgetting factor” to promptly respond to changes on monitored devices. A full characterization aiming in find a forgetting factor value able to find the best compromise between accuracy and response time together with tests executed on real signals were also reported
R&D ALLIANCE PARTNER ATTRIBUTES AND INNOVATION PERFORMANCE: A FUZZY SET QUALITATIVE COMPARATIVE ANALYSIS
No full textBecause R&D alliances are important means for fostering firm innovation performance,
research has investigated their key drivers. However, multiple configurations of R&D alliance
drivers may lead to firm innovation performance. Drawing upon the knowledge-based view of
alliances, we investigate configurations of R&D alliance factors leading to high innovation
performance in allied firms by focusing on partner attributes (i.e., technological relatedness,
competitive overlap, experience, relative size). Then, using a fuzzy set qualitative
comparative analysis, we dissect the configurations of these factors in 27 R&D alliances
formed by 54 telecom firms worldwide. We find that good R&D alliance partners are
technologically related competitors with no experience in forming R&D alliances.
Alternatively, competitors can achieve high innovation performance when they have
experience in doing R&D alliances and are not technologically related. Drawing on these
findings, we submit a set of propositions with relevant implications for the knowledge-based
view of alliances and coopetition research
Real-time Estimation of R, L, and C Parameters Under non Sinusoidal Conditions: A proposal
No full textModern electric and electronic devices frequently work with non sinusoidal waveforms, then, all the passive R, L, and C components present in these circuits are involved with non sinusoidal stimuli. Consequently, the behaviors of these components in presence of non sinusoidal environments have to be estimated. In previous researches authors proposed a suitable measurement method for the estimation of R, L and C parameters of passive components in non sinusoidal conditions. This paper deals with the realization of a real-time FPGA-based instrument, able to continuously update the estimated values of the considered components. Core of the realized instrument is the digital signal processing section that applies the previously proposed measurement method, based on a parameter estimation technique. This last can be implemented is a sequential (i.e. point by point) algorithm, suitable for the development on a FPGA platform. This implementation allows minimizing both required memory and computational burden. After a preliminary tuning of the measurement method, both the hardware and the software architectures of the realized measurement instrument are described. Experimental tests carried out in a suitable emulation environment and experiments on real R, L and C passive components are carried out in order to characterize the instrumen
