Complements or substitutes? The role of universities and local context in supporting the creation of academic spin-offs

In this paper, we analyze the extent to which University-Level Support Mechanisms (ULSMs) and Local-Context Support Mechanisms (LCSMs) complement or substitute for each other in fostering the creation of academic spin-offs. Using a sample of 404 companies spun off from the 64 Italian Science, Technology, Engineering, and Mathematics universities (STEM universities) over the 2000–2007 period, we show that the ULSMs’ marginal effect on universities’ spin-off productivity may be positive or negative depending on the contribution offered by different LCSMs. Specifically, in any given region, ULSMs complement the legislative support offered to high-tech entrepreneurship whereas they have a substitution effect with regard to the amount of regional social capital, regional financial development, the presence of a regional business incubator, regional public R&D expenses as well as the level of innovative performance in the region. Results support the idea that regional settings’ idiosyncrasies should be considered for universities to develop effective spin-off support policies. This paper contributes to the debate on the evaluation of economic policies supporting entrepreneurship.     

An informetric model for the success-index

Based on an idea by Kosmulski, Franceschini et al. (2012, Scientometrics 92(3), 621–641) propose to classify a publication as “successful” when it receives more citations than a specific comparison term (CT). In the intention of the authors CT should be a suitable estimate of the number of citations that a publication – in a certain scientific context and period of time – should potentially achieve. According to this definition, the success-index is defined as the number of successful papers, among a group of publications examined, such as those associated to a scientist or a journal. In the first part of the paper, the success-index is recalled, discussing its properties and limitations. Next, relying on the theory of Information Production Processes (IPPs), an informetric model of the index is formulated, for a better comprehension of the index and its properties. Particular emphasis is given to a theoretical sensitivity analysis of the index.     

Bridges or isolates? Investigating the social networks of academic inventors

We analyze the acquaintances of a sample of academic inventors and their paired controls to investigate the contribution of social networks to the generation of inventive ideas in academe. Prior to patenting, inventors work in networks of similar dimension and structure as those of their colleagues who do not invent. The ego-networks of the inventors are however more cohesive (denser), a circumstance that is often seen as associated to the exchange of more fine-grained information and to a greater climate of trust which facilitates long-term relationships and learning. Over time, both inventors and non-inventors extend their networks and become more central. In general, we found no evidence that after patenting inventors isolate or close their networks.

Termination outcomes of research alliances

We draw upon evolutionary economics and transaction cost economics to examine how alliance experience accumulation at the parent firm level and alliance features at the transaction level jointly and interactively shape the favorability of research alliances’ termination outcomes. Fifteen percent of the terminated alliances we examined were successful, 34% were failures, and 51% experienced an intermediate outcome in the form of contract expiration or unilateral withdrawal by a partner. We find that the effect of partner-specific experience on the favorability of termination outcomes is greater for non-equity alliances than for equity structures affording stronger formal governance mechanisms. Other forms of experience such as general alliance experience or prior alliances in the same technological area as the focal agreement have no such favorable consequences for alliance termination. The findings also indicate that alliance complexity adversely influences firms’ termination outcomes in alliances. We therefore find evidence in partial support of both evolutionary and transaction cost based arguments for the explanation of termination outcomes in research alliances.     

The effects of owner identity and external governance systems on R&D investments: A study of Western European firms

This paper builds on agency and institutional theory to extend the analysis of the effects of ownership and control on R&D investments by considering the influence of different types of ownership and of institutional corporate governance systems. Our empirical analysis is based on a unique dataset of 1000 firms publicly-traded in six European countries (France, Germany, Italy, Norway, Sweden and the UK). Controlling for industry- and firm-level effects, our findings show that higher shareholding by families is negatively associated with R&D investment. Moreover, widely-held firms invest less in R&D in the United Kingdom than in Continental European countries, thus suggesting the existence of a greater pressure towards the reduction of R&D in market-based governance systems. The results are robust against possible sample selection biases due to firms’ discretional R&D disclosure.     

The influence of core affect on cyclo-ergometer endurance performance: Effects on performance outcomes and perceived exertion

BackgroundCore affect is defined as the most general affective construct consciously accessible that is experienced constantly. It can be experienced as free-floating (mood) or related to prototypical emotional episodes. The aim of this study was to examine the influence of pleasant and unpleasant core affect on cyclo-ergometer endurance performance. Specifically, we considered the influence of pleasant and unpleasant core affect on performance outcomes (i.e., time to task completion) and rate of perceived exertion (RPE; Borg Scale, category ratio-10) collected during the task.MethodsThirty-one participants aged 20–28 years were recruited. Core affect was randomly elicited by 2 sets of pleasant and unpleasant pictures chosen from the international affective picture system. Pictures were displayed to participants during a cyclo-ergometer performance in 2 days in a counterbalanced order. RPE was collected every minute to detect volunteers’ exhaustion.ResultsThe study sample was split into 2 groups. Group 1 comprised participants who performed better with pleasant core affect, whereas Group 2 included participants who performed better with unpleasant core affect. Mixed between-within subjects analysis of variance revealed a significant 2 (group) × 2 (condition) × 5 (isotime) interaction (p = 0.002, η_p² = 0.158). Post hoc comparisons showed that participants who obtained better performance with pleasant core affect (pleasant pictures; Group 1) reported lower RPE values at 75% of time to exhaustion in a pleasant core affect condition compared to an unpleasant core affect condition. On the other hand, participants who obtained better performance with unpleasant core affect (unpleasant pictures; Group 2) reported lower RPE values at 75% and 100% of time to exhaustion in an unpleasant core affect condition.ConclusionFindings suggest differential effects of pleasant and unpleasant core affect on performance. Moreover, core affect was found to influence perceived exertion and performance according to participants’ preferences for pleasant or unpleasant core affect.     

Functional impact of emotions on athletic performance: comparing the IZOF model and the directional perception approach

The aim of this study was to examine the impact of emotions on athletic performance within the frameworks of the Individual Zones of Optimal Functioning (IZOF) model and the directional perception approach. Intensity, functional impact, and hedonic tone of trait and state anxiety, self-confidence, idiosyncratic emotions, and bodily symptoms were assessed in high-level Italian swimmers and track and field athletes (N = 56). Three standards of performance (poor, average, and good), derived from retrospective self-ratings across one to three competitions (a total of 90 observations), were used as independent variables in the analysis of variance of intensity, intra-individual, and direction scores of anxiety, self-confidence, idiosyncratic emotions, and bodily symptoms. Subsequently, intra-individual scores were categorized as near to or distant from optimal/dysfunctional zones and entered as the independent variable in the analysis of direction scores. The results provided support for the predictions stemming from both the IZOF model and the directional approach, as well as help in interpreting direction of anxiety and other idiosyncratic emotions within the IZOF framework. Athletes tended to perceive emotional levels approximating an individual's optimal zone as facilitative-pleasant, and emotional levels approximating an individual's dysfunctional zone as debilitative-unpleasant.
