Studies on the legitimacy challenges faced by hi-tech start-ups are still scarce, leaving room for research, and policymaking debate. Legitimacy issues may become difficult to face for hi-tech firms in comparison with other start-ups, because they work in an extreme environment where the technological challenges are at the edge of the scientific possibility. The paper proposes a conceptual model to grasp the relevance of three legitimacy drivers of the hi-tech start-ups for investment decisions. We investigated the ability of 30 hi-tech start-up firms to obtain financial resources from the US investors, employing a set-theoretic approach and carried out fuzzy-set Qualitative Comparative Analysis. Our findings clarify that the funding decisions of US investors are driven by the location of headquarter and R&D of hi-tech start-ups and by the educational experience of the founders. Our study has significant theoretical, practical, and policymaking implications. 相似文献

This paper analyses factors determining open environmental innovation (EI) and explores the possibility of embracing their tensions to achieve integrated environmental strategic goals. Building on recent literature linking open innovation and EI, the study assumes open EI strategic goals as a multidimensional construct based on the “synergistic and interwoven nature” of four identified enabling factors, that is, partners, knowledge, benefits, and motivations. A fuzzy‐set qualitative comparative analysis (fsQCA) based on Boolean algebra is conducted to analyse a set of 186 European companies operating in the telecommunication and information and communication technology (ICT) service industries. Making important theoretical, managerial, and policy contributions, this paper offers insights into the key factors enabling open EI and the tensional relationships within and between them. In doing so, it captures the non‐linear effects among these factors and the strategic goals related to an open EI strategy. It also suggests how the paradox theory might help in addressing the tensional dilemma of open EI strategy. 相似文献

Home injuries together, with road traffic accidents, are estimated to be the third cause of death in Italy (Arokiasamy and Krishnan 1994). However, as in most other countries, in Italy there is a lack of information on home injuries and on how differences in geographical patterns may influence the scope and magnitude of this phenomenon. By analysing a multipurpose large survey (Multiscopo) carried out annually, geographical heterogeneity in home injuries incidence rate can be investigated. The aim of this study is the assessment of possible differences in geographical patterns among the Italian regions making use of a re-analysis of Multiscopo home injury data. The study results show that Italian regions differ greatly in the number of home injuries. The geographical heterogeneity may be due to the unemployment rate and the incidence of poverty that is greater in the Southern and Insular regions than in other zones. Other socio-economic variables such as alcohol consumption can increase the risk of injury in the home. To prevent them it could be useful to organize campaigns aimed at increasing the awareness among people about this problem. 相似文献

We construct a monetary economy with aggregate liquidity shocks and heterogeneous idiosyncratic preference shocks. In this environment, not all agents are satiated at the zero lower bound (ZLB) even when the Friedman rule is the best interest‐rate policy the central bank can implement. As a consequence, central bank stabilization policy, which takes the form of repo arrangements in response to aggregate demand shocks, temporarily relaxes the liquidity constraint of impatient agents at the ZLB. Due to a pecuniary externality, this policy may have beneficial general equilibrium effects for patient agents even if they are unconstrained in their money balances. 相似文献

Information used to manage the business and support the decision‐making of stakeholders is being subject to an evolution. In this context, traditional financial reporting is considered not sufficient anymore. This has translated into a sharp increase in the number of firms that have begun to adopt emerging reporting practices. This study aims to examine the influence that both firm‐ and country‐specific characteristics have on the voluntary uptaking of integrated reporting internationally. In order to do so, it analyses a sample of 71 international listed companies that have adopted this reporting form in 2016. The results show that firms are more likely to implement integrated reporting if they are located in countries with a higher level of corruption perception and a better risk rating and that are considered as relatively more collectivist and feminist and with a long‐term orientation. Legal system has resulted to be not significant. As for firms' characteristics, large size, profitability, market‐to‐book ratio, and the size of the board are found to be significant variables. Moreover, the results indicate that the adoption of integrated reporting is not influenced by a higher level of leverage, firm efficiency and board diversity and independence. 相似文献

Existing tourism-destination investigations of Chinese texts remain weak, and no approach is available to realize Chinese context semantically and automatically. To resolve this, we provide a novel method based on qualitative analysis for studying the online opinions of Chinese tourists regarding the destinations to which they travel. Both traditional and simplified Chinese forums were chosen as the object of study. Spain was selected as a travel destination to evaluate the proposed method. After processing the natural language, unstructured Chinese content is analysed to derive the general sentiment and relevant topics regarding the destination through user comments on social media. The proposed method allows us to understand what tourists are interested in and how they form opinions about tourist destinations. 相似文献

Background: Tuberous sclerosis complex (TSC) is a multi-system genetic disorder in which renal manifestations occur in ~50% of children and 80% of adults. Since these often present alongside other manifestations, renal TSC is likely to incur significant costs. This study aims to quantify healthcare resource use (HCRU) and costs for renal TSC patients in the UK.Methods: TSC patients in the Clinical Practice Research Datalink (CPRD) linked to Hospital Episodes Statistics were identified from January 1987–June 2013. Clinical data were extracted over the entire history and costs were reported over the most recent 3-year period. HCRU was compared with a matched comparator cohort. Incremental costs were reported and the key cost drivers by primary manifestation category were identified by regression modeling.Results: A total of 79 renal TSC patients were identified with manifestations including chronic kidney disease stage 3–5 (with prevalence increasing with age) and renal angiomyolipoma. Renal TSC patients consistently reported greater HCRU than the comparator. Inpatient hospitalizations were more frequent for renal TSC patients (3.2 vs 1.6), but length of stay was comparable; however, 70.9% of renal TSC patients recorded no kidney-related procedures ever and averaged <1 test per year in the 3-year period. Average costs for renal TSC patients were nearly 3-fold greater than the comparator (£15,162 vs £5672). Costs increased with additional manifestation categories (£3600: only renal; £27,531: renal with ≥4 additional manifestation categories [25% of patients]). Additional nervous system and dermatology/psychiatric manifestations significantly (p?0.028) affected costs.Conclusions: Renal TSC patients have greater HCRU than the general CPRD population, likely to result from progression of renal disease and additional manifestations; however, surveillance for disease progression appears to be deficient. Inadequate monitoring may contribute to a lack of co-ordinated care and increased healthcare-associated costs. Efforts should be made to follow the TSC guidelines to effectively monitor and treat patients. 相似文献

Firms specialized in two different sectors lobby to induce the government to subsidize the type of education complementary to their production. Lobbying is endogenous. We show that, if lobbying is not costly, both sectors will lobby in equilibrium and the education policy will induce the same skill composition that would be chosen by the social planner. However, if lobbying is costly and there is sufficient asymmetry between the sectors, only one sector will exert pressure on the policy‐maker in the attempt to direct resources toward the type of education required by its production. Which sector will engage in lobbying depends on relative size, productivity, and price. We also provide some preliminary evidence that lobbying activity by firms may influence the production of skills needed by those firms. 相似文献

We examine the role of school grades as a signal of worker productivity under different examination systems in relation to
errors that may affect student performance. Firms use school grades as a signal of workers’ effective skills, taking into
account that these evaluations are effected by stochastic shocks. We show that more precise evaluation systems, being associated
with a higher reactivity of wages to school grades, induce students to provide more effort. Low ability students tend to react
less than high ability students. Moreover, individuals with low abilities may prefer less accurate evaluation systems. Nevertheless,
when productivity increases, these systems become less convenient and the number of individuals preferring them diminishes.
Our analysis highlights an important trade-off between centralised and decentralised evaluation systems. On the one hand,
frequent evaluations, typical of decentralised systems, weaken the impact on grades of those errors which influence student
performance and, so, reduce signal noise, while, on the other hand, different teachers generally adopt different performance
assessment standards, leading to noisier evaluations. 相似文献
