We explore how socially embedded life courses of individuals within Britain affect the resources they have available and their capacity to apply those resources to start-up. We propose that there will be common pathways to entrepreneurship from privileged resource ownership and test our propositions by modelling a specific life course framework, based on class and gender. We operationalize our model employing 18 waves of the British Household Panel Survey and event history random effect logistic regression modelling. Our hypotheses receive broad support. Business start-up in Britain is primarily made from privileged class backgrounds that enable resource acquisition and are a means of reproducing or defending prosperity. The poor avoid entrepreneurship except when low household income threatens further downward mobility and entrepreneurship is a more attractive option. We find that gendered childcare responsibilities disrupt class-based pathways to entrepreneurship. We interpret the implications of this study for understanding entrepreneurship and society and suggest research directions. 相似文献

Incubation has already proven to be of great value in promoting small and medium enterprise (SME) entrepreneurship activities and technological development in developed and developing countries. Incubation not only provides a diversified and integrated service for entrepreneurial ventures but also contributes upward to regional and national innovation and economic growth. Building upon the logic of co-evolution theory, this paper argues that incubation acts at the meso-level as a critical interface between macro-innovation systems and micro-business ventures. These multi-directional coupling elements in innovation ecology co-evolve to achieve collective interests and excellence, which in turn may stimulate technological development and social change. Important processes/mechanisms, including a policy kit and action, strategic networking, supportive associations, knowledge and intellectual capital management, among others, are discussed. Drawing on the national innovation system (NIS) and business incubation (BI) experience in Taiwan, we discuss the future prospects of incubation and innovation policies, including industrializing and globalizing incubation activities and virtual business incubation. 相似文献

This paper assesses the measurement errors inherent in segment reporting. Measurement errors are gauged by comparing the correlation
of segment results with their industry to the corresponding correlation for single line-of-business firms operating in the
same industry. The findings show that the measurement errors in segment information, particularly earnings, are larger than
those in the financial information reported by single line-of-business firms. The cross-sectional variation in the measurement
errors can be traced to cost/revenue allocations, management intervention in segment reporting, and the operational structure
of multi-segment firms. Market tests indicate that the information content of segment information is inversely related to
the estimated measurement errors.

The proposed method of Stochastic Non-smooth Envelopment of Data (StoNED) for measuring efficiency has to date mainly found application in the analysis of production systems which have exactly one output. Therefore, the objective of this paper is to examine the applicability of StoNED when a ray production function models a production technology with multi-dimensional input and output. In addition to a general analysis of properties required by a ray production function for StoNED to be applicable, we conduct a Monte Carlo simulation in order to evaluate the quality of the frontier and efficiencies estimated by StoNED. The results are compared with those derived via Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA). We show that StoNED provides competitive estimates in regard to other methods and especially in regard to the real functional form and efficiency. 相似文献

In the second half of 2009, the entire media agenda in Germany was dominated by the swine flu, next to the German Federal Parliament elections. Criticism was voiced in the media against the pharmaceutical industry for lobbying the nationwide swine flu vaccination, which was widely considered nothing but a product of the industry’s lobbying power. In order to avoid the usual interviews with lobbyists, we attempted to apply a new methodological framework approach in analysing lobbying processes and key stakeholders in the public sphere—and outside. Crucial to the diversified approach, which involves quantitative content analysis of media coverage and press releases, are interviews with journalists, lobbyists’ network analysis and internet research on biographies. Although a conspiracy could not be conclusively proven, the results do indicate associations that validate the criticism of the industry’s lobbying activities. 相似文献

The Brazilian cities as well as many of the large urban centers in the world continue to expand, increasing the demand for mobility and transport, while, at the same time, the same cities are investing in greenhouse gas (GHG) mitigation to avoid climate change. Brazil's urbanization rate increased from 26% in 1940 to almost 70% in 1980. During this period, the Brazilian population tripled and the urban population multiplied by seven. In 2010, the transport sector in São Paulo accounted for 71% of the total emissions released by the energy sector. Ethanol has been considered a fuel with less greenhouse gas emissions, when compared with fossil fuels. However, ethanol production would have to double to meet the expected demand. Electric vehicles (EVs) market is expanding around the world, and is also an option to reduce the transport emissions, if powered by clean electricity. To assess whether the adoption of EVs might bring more benefits than the current ethanol, we develop prospective scenarios supported by the Long-range Energy Alternatives Planning (LEAP) simulation tool, taking a bottom-up tank-to-wheel approach to consider the CO2 emissions of car in São Paulo. The scenario considering a substitution of 25% of gasoline-powered cars by EV in 2030 showed a reduction in energy consumption and CO2 emissions, around 15% and 26% respectively in that year in comparison with 2015. We discuss the interplay between ethanol and EV, also considering emission coefficients from life cycle analysis conducted in Brazil, and concluded EV will have higher positive impact on climate change mitigation than ethanol. 相似文献

It is well known that the price of a food in general and fish in particular is a function of a number of attributes such as species, product form, processing form and size. However, limited attention has been given to the influence of private labels, production method, eco‐labels and promotions. We use a unique dataset which identifies these attributes in the German seafood market. We estimate a hedonic price function, and our results highlight the importance of brand and labels for seafood prices in Germany. Our results also suggest that private label products are discounted by 20%, while branded products achieve substantial price premiums, as do fish products from aquaculture. 相似文献

Forecasting approaches that exploit analogies require the grouping of analogous time series as the first modeling step; however, there has been limited research regarding the suitability of different segmentation approaches. We argue that an appropriate analytical segmentation stage should integrate and trade off different available information sources. In particular, it should consider the actual time series patterns, in addition to the variables that characterize the drivers behind the patterns observed. The simultaneous consideration of both information sources, without prior assumptions regarding the relative importance of each, leads to a multicriteria formulation of the segmentation stage. Here, we demonstrate the impact of such an adjustment to segmentation on the final forecasting accuracy of the cross-sectional multi-state Kalman filter. In particular, we study the relative merits of single and multicriteria segmentation stages for a simulated data set with a range of noise levels. We find that a multicriteria approach consistently achieves a more reliable recovery of the original clusters, and this feeds forward to an improved forecasting accuracy across short forecasting horizons. We then use a US data set on income tax liabilities to verify that this result generalizes to a real-world setting. 相似文献

ABSTRACT This semi-ethnographic research is an exploration of the creative process from the unique perspective of the circus business. It examines from an interpretivist perspective how circus companies collaborate in the generation and manifestation of ideas, balancing the demands of maintaining a strict physical training regime with devising the circus aesthetic for an expectant audience. The focus of the research is a retired aerial trapeze artist and company director supported by contributions from semi-structured interviews with nine contemporary circus directors and an arts policy officer. Issues were identified from attending three circus network events providing an opportunity to conduct an online questionnaire resulting in thirty-nine responses. Following thematic analysis across all data, key themes emerge identifying networked creativity, productive creativity and intrinsic creativity which correlates to conceptual models of creativity and innovation in organisations. Preliminary findings suggest that networks, skills and intrinsic motivation are integral to creativity within the circus business environment. Whilst this may not be unique to circus, the depth to which it is experienced and its inter-relationality to the form, is readily apparent. This has potential interesting implications for further research within a circus context as well as implications for further exploration of practice in other creative sectors. 相似文献
