Entrepreneurial activity unfolds in a dynamic environment that challenges business viability. We utilize grounded theory as a novel type of reflection to explain and interpret whether and how innovation can afford survival benefits to firms. The premise is the application of a methodological approach with reflexive properties to advance scientific rigor in “reflections.” The idea underlying our reflection was to use innovation as the point of departure, review the literature, conceptualize ideas, and finally link the concepts that emerged as components of a framework. Our view of the firm resembles a viable entity that changes, constantly striving to meet and balance internal potentials and external complexities, while innovation per se involves change that is made possible by entrepreneurship. We bring together our personal and professional backgrounds and implement the European scholarly tradition on innovation and Viable Systems approach to scrutinize innovation’s interactions and relations. We linked boundary conditions, opportunities, and complementary assets to innovation. Effectively, our analysis conceptualizes innovation as autopoiesis in entrepreneurship and demonstrates its central role as the vehicle to exploit changes that ensure firm viability.  相似文献

This study sheds light on our understanding of when boards dismiss the CEO by considering the inherent conflict created by the board's advisory role when the firm underperforms. Using a sample of US firms listed in Standard & Poor's ExecuComp for the period 2000–2012 we find that, when a firm underperforms, extreme resource reallocation increases the likelihood of CEO dismissal. This relationship is positively moderated by the board's industry and CEO experience. The study contributes to the literature on corporate governance by identifying the conditions that trigger dismissal of the CEO in light of boards’ motive to protect their reputation.  相似文献

ABSTRACT

Are female and male trainees similar or different in their reaction to training programmes, specifically regarding their subjective task value and motivation to transfer? According to the gender similarities hypothesis, women and men are alike on most psychological variables. However, according to research in organizational behaviour, female and male employees differ on certain aspects, such as their job satisfaction and work identity. To test these two views on gender similarities and differences in the context of human resource development and training evaluation, the present study examined the extent to which gender moderated reactions to training. Based on the expectancy-value theory of motivation and self-determination theory, a web-based questionnaire was used to measure six training reactions: intrinsic value, attainment value, utility value, perceived relative cost, autonomous motivation to transfer, and controlled motivation to transfer. The results indicated that women and men differed in their ratings of attainment value but were similar for the remaining five reaction measures. These outcomes support the gender similarities hypothesis. The findings are discussed in terms of their theoretical implications for modelling gender effects in HRD research and their practical significance for promoting training effectiveness and transfer of training.  相似文献

For modelling the location of pyramidal cells in the human cerebral cortex, we suggest a hierarchical point process in that exhibits anisotropy in the form of cylinders extending along the z-axis. The model consists first of a generalised shot noise Cox process for the xy-coordinates, providing cylindrical clusters, and next of a Markov random field model for the z-coordinates conditioned on the xy-coordinates, providing either repulsion, aggregation or both within specified areas of interaction. Several cases of these hierarchical point processes are fitted to two pyramidal cell data sets, and of these a final model allowing for both repulsion and attraction between the points seem adequate. We discuss how the final model relates to the so-called minicolumn hypothesis in neuroscience.  相似文献

Abstract

Possible chronotoxic effects were the reason to study chemical workplace exposure under the special condition of shiftwork. Eight shiftworkers occupationally exposed to acetone vapours and eight controls were investigated during fast-rotated shiftwork. The mean concentration of acetone during the shifts was close to 1000 ppm (2400 mg/m3). Data on well-being and acute symptoms, but not on performance, indicate that the exposure contributed mainly in an additive way to the negative effects of shiftwork. As a consequence, the exposed shiftworkers revealed enhanced impairments during the night-shift.  相似文献

Service quality improvement has become an imperative in today's service firms. In this paper, we present a modeling framework that combines marketing and operations viewpoints for resource allocation. The framework can be used to allocate resources to the different stages of a multistage service system, where the manager's goal is to improve customers' perceptions of service quality, given some budget. Optimal allocation guidelines are provided, and the interplay of three factors on the resulting allocation scheme is captured. These factors are the current level of customers' perceptions of service quality at each stage, the cost of implementing a service quality improvement at each stage, and the importance placed by customers at each stage. Sensitivity analysis to provide additional managerial insights is also performed. We demonstrate the applicability of the modeling framework, using data from a real life health care environment. Model limitations and future research are also discussed.  相似文献

The allocation of seminar applicants is an important issue in educational planning, and each semester a university administration has to deal with this kind of problem. The task here is to reconcile the preferences and priorities of the students, professorships and the university administration itself. This paper shows that if the planning procedure is based on a simple selection strategy, the capacity utilization can be suboptimal; this result is evidenced by a simulation study. To remedy this deficit—and to justify the respective interests—we propose a mixed-integer goal programming approach for assigning students to seminar courses. In addition, we show that this problem can be reformulated into a linear one. All investigations in this paper are illustrated by a real-world application for the University of Hagen, Germany.  相似文献

This paper analyzes whether taxation has an influence on the location decisions of multinational enterprises. We employ a novel set of 22 tax variables, such as the taxation of dividends and capital gains, withholding taxes, the existence of a group taxation regime, and thin capitalization rules. Furthermore, we use the Tax Attractiveness Index, a new aggregate measure containing the 22 tax variables. Our count data regression analysis is based on a novel hand-collected dataset consisting of the subsidiaries of German DAX30 companies in 97 countries. Controlling for non-tax effects, we find that a country’s tax environment has a significantly positive effect on the number of German-controlled subsidiaries and, therefore, on the location decisions of German multinational enterprises. Specifically, our analysis reveals that German multinational firms place affiliates in countries that offer favorable statutory tax rates, withholding taxes, double tax treaty networks, and holding incentives. Additionally, we find that the Tax Attractiveness Index has explanatory power in subsidiary location decisions and, therefore, it can be used as alternative composite measure, for example, when 22 single tax variables are not at disposal.  相似文献

This study examines the effects of certificates and deadlines on student performance. It exploits time lags in reforms of two similar degree programs at a business school, which create quasi-experimental settings. Students’ performance is found to increase if certificates are awarded to them early in their program. Deadlines to pass exams prevent them from submitting blank sheets to fail and resit exams. Both effects are stronger among average students compared to high-ability or low-ability students. These findings show that the policies that govern degree programs can create incentives for students to improve performance. It is important for universities to understand the behavioral implications of such policies when designing degree programs.  相似文献
