Research Summary Entrepreneurship and innovation are social and relational processes that occur in diverse contexts involving multiple stakeholders. Recently, research in entrepreneurship has begun to explore entrepreneurial processes through the lens of gender. However, unlike its entrepreneurship counterpart, innovation research has paid limited attention to gender dynamics. Indeed, the majority of studies on innovation focus on products, processes or organizations, with the individual often not ‘seen’. This special issue recognizes the intertwined nature of gender, innovation, and entrepreneurship, and in doing so, presents five articles that develop new theory and provide new empirical evidence on the topic of innovation in women’s entrepreneurship. Collectively, they offer new perspectives and open new avenues for future work. In structuring this editorial, we present an overview of the state of the field, provide a multilevel future research agenda, and introduce the articles that comprise this special issue. Managerial Summary Despite the importance of entrepreneurship and innovation for economies and societies worldwide, innovation and gender are rarely explored together. Indeed, limited attention has been placed on the gendered nature of the relations among innovators, entrepreneurs, and processes. This special issue includes five articles which address this gap from multiple perspectives. The editorial describes the state of the field prior to the special issue, introduces the special issue articles, and identifies a multilevel perspective suggesting avenues for further investigation.

This study investigates the retention of target CEOs in the aftermath of acquisitions by comparing target founder and professional CEOs. Considering insights from resource-based view, managerial rent perspective, studies on acquisition implementation, and the literature on founder-CEOs, we argue that target founder-CEOs are resourceful assets for acquirers for implementation purposes; ergo, they are more likely to be retained than target professional CEOs. Target founder-CEOs, owing to their unique firm-specific human capital, have greater acquisition implementation abilities than target professional CEOs. They also have greater monetary incentives to deploy their implementation abilities to the benefit of acquirers. Furthermore, we claim that these effects are stronger, thus contributing to a higher retention rate of target founder-CEOs than their professional peers when acquisitions are technology-driven, and target firms are young. Results from a sample of small high-tech firms acquired by large incumbent firms confirm our predictions.

Up until now, this blazar had not been the subject of any detailed MWL observations. It has a rather hard photon index at GeV energies and was considered a candidate extreme high-synchrotron-peaked source. MAGIC observations resulted in the first-time detection of the source in VHE with a statistical significance of 7.6σ. The average integral VHE flux of the source is 6 ± 1 per cent of the Crab nebula flux above 400 GeV. X-ray coverage was provided by Swift-XRT, XMM-Newton, and NuSTAR. The long continuous X-ray observations were separated by ∼9 h, both showing clear hour scale flares. In the XMM-Newton data, both the rise and decay time-scales are longer in the soft X-ray than in the hard X-ray band, indicating the presence of a particle cooling regime. The X-ray variability time-scales were used to constrain the size of the emission region and the strength of the magnetic field. The data allowed us to determine the synchrotron peak frequency and classify the source as a flaring high, but not extreme synchrotron-peaked object. Considering the constraints and variability patterns from the X-ray data, we model the broad-band spectral energy distribution. We applied a simple one-zone model, which could not reproduce the radio emission and the shape of the optical emission, and a two-component leptonic model with two interacting components, enabling us to reproduce the emission from radio to VHE band. © 2021 The Author(s) Published by Oxford University Press on behalf of Royal Astronomical Society., The financial support of the German BMBF, MPG, and HGF; the Italian INFN and INAF; the Swiss National Fund SNF; the ERDF under the Spanish Ministerio de Ciencia e Innovacion (MICINN) (FPA201787859-P, FPA2017-85668-P, FPA2017-82729-C6-5-R, FPA201790566-REDC, PID2019-104114RB-C31, PID2019-104114RB-C32, PID2019-105510GB-C31, PID2019-107847RB-C41, PID2019107847RB-C42, PID2019-107847RB-C44, PID2019-107988GBC22); the Indian Department of Atomic Energy; the Japanese ICRR, the University of Tokyo, JSPS, and MEXT; the Bulgarian Ministry of Education and Science, National RI Roadmap Project DO1268/16.12.2019 and the Academy of Finland grant nr. 317637 and 320045 are gratefully acknowledged.

While radical innovation brings extensive economic rewards to firms, it is an activity fraught with risk. Prior research has shown that such risks mainly stem from organizational arrangements (at the level of individuals, teams, firms, and inter firm collaborations), which are inadequate or inefficient to support radical innovation. The papers in this special issue on “Organizing for Radical Innovation: Exploring Novel Insights” take stock of past work and provide novel insights about how to organize for radical innovation. The overarching idea linking them is that radical innovation hinges on the creation of fundamentally new knowledge and the continuous stimulation of creativity. Thus, organizational arrangements that support such processes play a crucial role in explaining and predicting the successful commercialization of breakthrough ideas, radically new technologies, and solutions. In particular, the field of science, which in essence aims for the systematic production of new knowledge, can be a valid source of inspiration for how individuals, teams, firms, and interfirm collaborations should organize for radical innovation. Moving from these premises, in this introductory paper, we offer an overview of the topic of organizing for radical innovation and highlight possible linkages with the organizing principles. Then, we summarize the main insights from the papers in this special issue and use their core ideas to sketch a novel research agenda for scholars working at the intersection of organization theory, economics of science, and management of innovation.

This article examines the sensitivity of employment to sales contractions in a negative growth scenario for high-tech entrepreneurial ventures. Using the lens of transaction cost economics, we move from the centrality of human capital for these firms to theoretically discuss and empirically test the moderating effect of venture capital financing on the employment-sales relationship. In doing so, we take into account (i) the identity of the investor, distinguishing independent, corporate and governmental venture capital investors, and (ii) the presence and composition of a syndicate.

In October 2009, the Council of the European Union adopted the Directive on Sustainable Use of Pesticides (EU 128/2009/EC). This directive establishes a framework to achieve the sustainable use of pesticides by reducing the risk and impacts of pesticide use on both human health and the environment, and promoting the use of integrated pest management and of alternative approaches or techniques. These risks thus need to be assessed using appropriate risk indicators. The OPERA Research Centre organised an expert working group and has had several consultations with stakeholders in order to identify a common way of thinking in evaluating and identifying the factors that should be considered in selecting each indicator. Harmonised criteria have been suggested to allow the selection of the most appropriate indicators, focusing on the use phase of pesticide, as requested by the sustainable use directive. The proposed methodology has led to a sharing of perspectives and knowledge between the experts involved, and some principles have been identified to help national regulatory institutions to estimate general trends in pesticide risk reduction.

BACKGROUND: 1,3-Dichloropropene (1,3-D, CAS No. 542-75-6) is a broad-spectrum soil fumigant used to control numerous species of soilborne plant-parasitic nematodes. 1,3-D consists of two isomers, (Z)- and (E)-1,3-D. There are a number of low-level chlorinated compounds that could potentially be produced as a part of the 1,3-D manufacturing process. 1,3-D and its metabolites, as well as potentially related chlorinated compounds, represent potential groundwater contaminants. RESULTS: This study has investigated the hydrolytic stability, under biotic and abiotic conditions in the laboratory, of an extensive representative list of 1,3-D and potentially related chlorinated compounds in order to predict their environmental fate. All of these compounds showed intrinsic hydrolytic instability under both abiotic and biotic test conditions. Furthermore, a monitoring programme was carried out. Twenty-five wells were monitored in five Italian regions characterised by historical and existing use of 1,3-D. The parent compound, its two major metabolites and potentially related chlorinated compounds were not detected in the well water at > 0.1 µg L−1 at any sampling location. CONCLUSION: The soil fumigant (E,Z)-1,3-D, its metabolites and potentially related chlorinated compounds constitute a low risk to groundwater. Copyright © 2011 Society of Chemical Industry

Electrospinning technique was used to prepare the nanofibres of pure and Europium (Eu)-doped titania with Eu content of 3-10%mol. The solution was electrospun in air at room temperature. The obtained fibrous mats were thermally treated at 500 or1000°C. Morphology and phase analyses of the resulting fibrous ceramic mats were carried out by using SEM and X-ray diffraction (XRD), while the surface chemical composition was investigated by XPS. Annealed mats consisted of randomly oriented fibres with fairly uniform and nanometric diameter, dependent on the doping level. The main titania phase in the samples, heated at 500 °C, was anatase, whereas rutile phase with small traces of Eu 2 Ti 2 O 7 were identified in the samples calcined at 1000 °C. From the XPS analysis, it was determined that all the samples were composed of Ti 4+ and Eu 3+ species. XPS quantification of annealed samples revealed a surface enrichment with Eu. XPS depth profiles demonstrated that the chemical composition of the samples was constant. Moreover, it was observed that the Ti 4+ reduction, induced by ion sputtering, decreased in the samples with higher concentration of Eu dopant.

Yttrium–iron garnet (YIG)-based ceramics are largely used in microwave devices, sensors, lasers, phosphorescent sources, and magneto–optical applications. In this research, high-density, single-phase Gd(0.4)-YIG were obtained by spray drying starting from nonstoichiometric, iron-rich, metal nitrate solutions. Aqueous metal nitrate solutions, containing polyvinyl alcohol (PVA) and polyethylene glycol (PEG), were prepared and sprayed to obtain precursor powders. In some cases either sulfuric acid or hydrochloric acid were added to the initial solution. On the basis of differential thermal analysis and thermogravimetry analysis, as-sprayed powders were calcined between 600°C and 1200°C and then characterized by induced coupled plasma spectroscopy, X-ray diffraction, and high-temperature X-ray diffraction. According to thermal dilatometry results, powders calcined at 1200°C were sintered in air up to 1470°C. The microstructure of sintered ceramics was made up of fine grains, being an average size of about 10 μm. It was found that addition of an inorganic acid to the precursor solution is essential to obtain high-density (98%) sintered materials. Ferromagnetic resonance linewidth (ΔH−3 dB) measurements on sintered materials were also performed.

The possibility of using electrospinning to deposit, and simultaneously electrically pole, polymeric mats containing nonlinear optical (NLO) molecules is studied. Disperse Red 1 (DR1) chromophore dispersed into polymethyl methacrylate (PMMA) fibers is chosen as test system. Aligned fibers of DR1/PMMA are deposited by means of the rotating collector electrospinning technique. The processing parameters are optimized to obtain an oriented texture of fibers and the NLO activity is characterized by means of second harmonic generation measurements. Comparison with spin coating and corona poling samples of the same material is discussed. The results point toward a low efficiency of chromophore orientation for the electrospun samples in comparison to the poled ones. An improvement in the electrospinning apparatus is proposed to enhance the chromophore orientation in the polymeric fibers. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40913.
