Abstract
Purpose
This paper aims to derive a reduced-order model for the heat transfer across the interface between a millimetric thermocapillary liquid bridge from silicone oil and the surrounding ambient gas.
Design/methodology/approach
Numerical solutions for the two-fluid model are computed covering a wide parametric space, making a total of 2,800 numerical flow simulations. Based on the computed data, a reduced single-fluid model for the liquid phase is devised, in which the heat transfer between the liquid and the gas is modeled by Newton’s heat transfer law, albeit with a space-dependent Biot function Bi(z), instead of a constant Biot number Bi.
Findings
An explicit robust fit of Bi(z) is obtained covering the whole range of parameters considered. The single-fluid model together with the Biot function derived yields very accurate results at much lesser computational cost than the corresponding two-phase fully-coupled simulation required for the two-fluid model.
Practical implications
Using this novel Biot function approach instead of a constant Biot number, the critical Reynolds number can be predicted much more accurately within single-phase linear stability solvers.
Originality/value
The Biot function for thermocapillary liquid bridges is derived from the full multiphase problem by a robust multi-stage fit procedure. The derived Biot function reproduces very well the theoretical boundary layer scalings.

Abstract
Purpose
The purpose of this paper is to discuss the concept of innovative performances for science parks as a framework for understanding how effectively human and structural capital (i.e. intellectual assets) are leveraged. The key point is fostering main determinants to investigate and/or make sense of key management activities/factors shaping the evolution and performance of knowledge creating processes.
Design/methodology/approach
The study was based on the quantitative and qualitative values, for the period 2000-2011, gathered from a sample of 901 public and private organizations located in the 21 European Union (EU) countries. With regard to the methodology, the hypothesis testing first required an analysis of the correlations between the investigation variables, and then the use of regression analysis to study the relationships between the innovative performance of the research institutions, and the financial, organizational and knowledge characteristics of the science parks investigated.
Findings
The empirical research shows that: the allocation of public resources does not influence most of the selected indicators of performance, with the exception of the negative effect seen for the number of patents; the resources provided by venture capitalists have a positive effect on all of the indicators of performance of the science park; the science parks of greater dimensions have better performances; the positive impact of the systemic relationships seems to have an effect that is limited to the increase in the number of contracts stipulated with industry; the number of publications produced by researchers of the science parks seems to have an unclear effect on the innovative performance; and an increase in the number of researchers enhances the innovative performance of the science parks.
Research limitations/implications
It seems appropriate to suggest some research lines that arise from the limits of this work. In particular, it should be stressed that there is a need to enlarge the sample investigated to embrace local innovation systems outside the EU, so as to provide further validation to the empirical results of this research.
Practical implications
This research has some practical implications of notable interest at the level of European policies. Interventions of public policies supporting innovation should not be concentrated on the increase of public funding but on increasing private capital investment.
Originality/value
This paper aims to extend literature about factors explaining the financial, organizational and cognitive performance of science parks in Europe.

– The purpose of this paper is to investigate the effect of being located in a science park (SP) on the level of a firm's intellectual capital (IC) performance.
Abstract
Purpose
The purpose of this paper is to investigate the effect of being located in a science park (SP) on the level of a firm's intellectual capital (IC) performance.
Design/methodology/approach
Using a sample of 183 Italian firms (i.e. 61 tenant and 122 non-tenant firms), and through the GLS technique, the authors regress the firms’ IC performance across various explicative variables including a dummy that discriminates tenant and non-tenant firms.
Findings
Consistently with expectations, the results show that the location of a firm in a SP leads to improved IC performance. Moreover, the authors find that some other firm characteristics, such as size, age, and leverage, are important predictors of its IC-based performance.
Research limitations/implications
The sample is small and the impact on performance might be biased by factors related to the regional context (e.g. level of industrialization, quality of education, and science system).
Practical implications
Implications for policy makers: support the growth of firms in SPs especially in those industries full of firms with scarce performance in IC. Implications for SP managers: they could “sell” (in terms of marketing) to both entrepreneurs to attract and policy makers this result. Implications for institutional investors: they should look at SPs with greater interest to find high-quality firms and improve their screening activity.
Originality/value
This paper aims to extend literature about factors explaining the level of a firm's IC performance and the current understanding of the impact of SPs at firm level.

Abstract
Purpose
This paper examines the leading publication trends including the extent and impact of intellectual capital research in the Journal of Intellectual Capital (JIC) over a two-decade period (2000–2020). The bibliometric analysis offers the description of publications trends such as key authors, articles, cited references, institutions and countries— in other words the extent and impact in the field. This paper also presents the knowledge structure (including conceptual, intellectual and social structures) of JIC, that is prominent themes, co-citation and bibliographic networks.
Design/methodology/approach
In order to achieve research objectives, we collected the bibliographic information of the articles published in JIC for the period 2000 to 2020 from the Scopus database on 11.04.2020. The bibliographic information of 737 documents were analysed using to open source analysis tool, that is bibliometrics package in r software and VOSviewer. These tools were used to create the graphical visualization of bibliographic data on basis of co-occurrence, co-citation and bibliographic coupling.
Findings
The results show that the journal is progressing in terms of publication quantity and reputation in the field. To date, 737 documents have been published in JIC, which includes 659 research articles, eight editorials, seven notes and 63 review papers. This paper also portrays the author impact list in terms of most impactful articles published in JIC. Country-wise Italy, Australia, and USA exert maximum influence on JIC scholarship.
Originality/value
Bibliographic analysis offers a comprehensive understanding of past trends and presents the future direction of a journal.

Abstract
Purpose
Recognising the increasing relevance of digital platforms in socio-economic dynamics, the paper aims at investigating in which ways digital platforms can influence the economic performances of Italian small and medium enterprises (SMEs) actively engaged in foreign countries.
Design/methodology/approach
The paper adopts the interpretative lens provided by the exploration–exploitation dichotomy within current studies in knowledge management for defining knowledge-based factors able to influence the economic performance of Italian SMEs in foreign countries. An explorative study on secondary data related to 746 Italian SMEs is conducted for testing via structural equation modelling (SEM) the positive relationships between (1) SME's investment in information and communication technologies (ICT), (2) number of languages available for the SME's website and (3) number of languages available for SME's social pages and SME's return on sales (ROS) in foreign countries.
Findings
The results underline the key role of exploitation factors in terms of influence on SME's performance in foreign countries.
Originality/value
The paper enriches current studies about international marketing providing preliminary evidence about the key role of exploitation factors in influencing SME's performance in foreign countries.

Abstract
Purpose
Dealing with intellectual capital (IC), the purpose of this paper is to provide a strategic tool for management activities in knowledge-based organizations. In particular, in the contribution, an integrated framework for intangibles’ representation, evaluation and control in Science Parks is developed.
Design/methodology/approach
Starting from a review of the main instruments for measuring intangible resources in an organization, an integrated model of IC for Science Parks is formulated.
Findings
The paper demonstrates that Science Parks are big repositories of knowledge but they are neither familiar with the IC management nor with the use of methodologies functional for the resources representations and for the variations dynamics of their value. Thereby it answers to questions related to the IC process representation, responding to managerial exigencies and to measurability and repeatability as strategic activities for business running.
Originality/value
Unlike the great number of studies on IC that formulate objective metrics of the value of firms’ intangible assets, the paper presents a model not to describe but to shape processes in a knowledge-based organization and to achieve and communicate results both for management and for increasing transparency of communication with external stakeholders.

Se Heine non giunse fino a Roma, in compenso vi arrivarono altri non meno illustri tedeschi, il cui genio si immortalò nel campo musicale. Per non parlare di Händel, che visitò Roma nel 1707, nè di Gluck, che vi venne nel 1756, ricorderemoper il'700 — Wolfango Amedeo Mozart e — per 1'800 — Riccardo Wagner.
