Abstract

This paper investigates the identity work of science-based entrepreneurs in two very different country contexts: Finland and Russia. Building on the literature investigating role identities, we first analyse the identification of individuals with the roles of a scientist and an entrepreneur; and second, how individuals manage the boundary between these two roles. Methodologically, we take a narrative approach, which regards life stories as identity constructions. Our empirical data consist of 23 biographical interviews with science-based entrepreneurs that are inductively analysed. Our findings show that the Russian informants considered being a scientist a salient part of their self-identification, distanced themselves from the role of an entrepreneur, and set discursive boundaries to segment the two roles. For the Finnish informants, identification with the professional roles as a scientist or as an entrepreneur was less salient for the personal identity as they make a clear distinction between ‘what one does’ and ‘who one is’. They also view the two roles as integrated rather than segmented, and have no significant need to justify the border-crossing between them. Our contribution is in demonstrating how science-based entrepreneurs’ identity work is influenced by importance and meanings attached to different work roles, and how these are contextualised.  相似文献

According to the US EIA (2009, www.eia.doe.gov), out of the 15 largest oil producing nations in the world, 7 are not OPEC members, namely Brazil, Canada, China, Mexico, Norway, the Russian Federation, and the United States of America (USA). This paper investigates the causal relationship between energy consumption and economic growth for these non-OPEC oil producing countries. Real GDP per capita is used to measure economic growth; whereas; energy consumption is represented by four sub-variables (electric power, oil, natural gas, and coal energy). Using a panel data covering (1969–2009), this study employs the Pedroni (Econometric Theory, 20, 597–627, 2004) approach to determine cointegration and the (Econometrica, 55, 251–276, 1987) two-step procedure to explore short and long run causal effects. The results suggest that there are long run relationships between the real GDP, labour force, real capital, oil consumption, electricity consumption, gas consumption and coal consumption. Further analyses show that real GDP and oil consumption Granger cause real gross capital formation in the short run; real gross fixed capital and electricity consumption cause oil consumption in the short run; and also oil consumption and gas consumption cause electricity consumption in the short run.  相似文献

This paper presents data from a survey of large and medium-sized industrial enterprises in Ukraine after privatization. To analyze this data, regression equations are estimated and explain the response of restructuring and performance indicators to ownership structures, competitive pressures, and hardening budget constraints. While ownership matters less for restructuring activity than competition and budget constraints, concentrated outside ownership does have a significant positive impact on the firm's performance. This research was financially supported by a grant from the International Association for Promotion of Cooperation with Scientists in the New Independent States of the Former Soviet Union (952-0280) and by a Research Fellowship provided by Konferenz der Deutschen Akademien der Wissenschaften, sponsored by Volkswagen Stiftung.  相似文献

Large US firms modify top executives’ compensation before pension-related events. Top executives receive one-time increases in pensionable earnings through higher annual bonuses one year before a plan freeze and one year before retirement. Firms also boost pension payouts by lowering plan discount rates when top executives are eligible to retire with lump-sum benefit distributions. Increases in executive pensions do not appear to be an attempt to improve managerial effort or retention and are more likely to occur at firms with poor corporate governance. These findings suggest that in some circumstances managers are able to extract rents through their pension plans.  相似文献

In this article we clarify mechanisms of genetic regulation of human aging and longevity traits. The objective of this article is to address the issues in previous research of not reaching a genome-wide level of statistical significance and lack of replication in the studies of independent populations. We performed GWAS of human life span using different subsets of data from the original Framingham Heart Study cohort corresponding to different quality control procedures, and we used one subset of selected genetic variants for further analyses. We used a simulation study to show that this approach to combining data improves the quality of GWAS with FHS longitudinal data to compare average age trajectories of physiological variables in carriers and noncarriers of selected genetic variants. We used a stochastic process model of human mortality and aging to investigate genetic influence on hidden biomarkers of aging and on dynamic interaction between aging and longevity. We investigated properties of genes related to selected variants and their roles in signaling and metabolic pathways and showed that the use of different quality control procedures results in different sets of genetic variants associated with life span. We selected 24 genetic variants negatively associated with life span and showed that the joint analyses of genetic data at the time of biospecimen collection and follow-up data substantially improved significance of associations of 24 selected SNPs with life span. We also showed that aging-related changes in physiological variables and in hidden biomarkers of aging differ for the groups of carriers and noncarriers of selected variants. The results of these analyses demonstrated benefits of using biodemographic models and methods in genetic association studies of these traits. Our findings showed that the absence of a large number of genetic variants with deleterious effects may make substantial contribution to exceptional longevity. These effects are dynamically mediated by a number of physiological variables and hidden biomarkers of aging. The results of these research demonstrated benefits of using integrative statistical models of mortality risks in genetic studies of human aging and longevity.  相似文献

This paper studies the determinants of Russian adult mortality controlling for both individual and household heterogeneity. We employ survival analysis and utilize 12 rounds of the Russian Longitudinal Monitoring Survey spanning a 14‐year period. Although confirming the crucial role of excessive alcohol consumption in shaping adult mortality risks in Russia, the results are original in several other respects. We find empirical support for the importance of relative status measured in non‐income terms in shaping mortality hazards. We find evidence of the influence of labour market behaviour, and sectoral and occupational mobility in particular, on longevity. The detrimental role of smoking to health is found to be comparable with the role of excess alcohol consumption, which is novel in the Russian context where the influence of smoking is typically downplayed in comparison with alcoholism. Finally, we find no micro evidence in support of the political economy view based on a positive correlation between low alcohol prices and high mortality rates found in regional‐level data.  相似文献

In this paper, we probe the relationship between institutions and internationally oriented innovation. For the first time, we use Patent Cooperation Treaty statistics as a new source of national-level data on the inventive activities of internationally oriented innovators, which we refer to as “global innovators.” One third of global innovators are small- and medium-sized enterprises (SMEs). We apply these new data and investigate the effects of corruption and business climate on patenting activity. It is ascertained herein that the inventive activity of global innovators has a linear relationship with institutional factors, while there is no observed relationship between the quality of the institutional environment and PCT patenting by multinational enterprises (MNEs).  相似文献

This exploratory study uses the learning‐network theory as a framework to investigate how managers and employees differ in their preference for the human resource development (HRD) activities of employees and in the functions they attribute to HRD. The research design was quantitative and cross‐sectional. Data collection took place in six countries in Europe, Asia and North America. A new instrument was used, which views work improvement (WI), career development (CD) and personal development (PD) as three main functions of HRD that can serve managers and employees. Results show that managers and employees prefer different HRD activities for employees to undertake; respectively, formal courses and programs over job experiences, and vice versa. The two groups also differ in the scores they give to WI and PD as relevant functions that employee participation in HRD can provide. It is concluded, therefore, that differences between managers and employees in their views of the relevance of HRD activities should be taken into account in theory and practice when organizing employees’ HRD activities.  相似文献

We investigate how short-lived liquidity supply due to order cancellations affects the order-placement behavior of slow traders. When order cancellations increase, slow traders submit fewer and less aggressive orders. Both short- and long-lived liquidity supply have positive effects on the market overall, reducing spreads and increasing depth. We conclude that it is not necessary to require limit orders to have a minimum lifespan. We develop econometric and machine-learning frameworks that allow traders to predict whether a quote is likely to have a short or long life, increasing the ability of slow traders to respond strategically to changing order flow.  相似文献

We examine a technology-adoption game with network effects in which coordination on either technology A or technology B constitutes a Nash equilibrium. Coordination on technology B is assumed to be payoff dominant. We define a technology’s critical mass as the minimal share of users, which is necessary to make the choice of this technology the best response for any remaining user. We show that the technology with the lower critical mass implies risk dominance and selection by the maximin criterion. We present experimental evidence that both payoff dominance and risk dominance explain participants’ choices in the technology-adoption game. The relative riskiness of a technology can be proxied using either technologies’ critical masses or stand-alone values absent any network effects.  相似文献
