Who Wants to Be an Intrapreneur? Relations between Employees’ Entrepreneurial, Professional, and Leadership Career Motivations and Intrapreneurial Motivation in Organizations

This paper reports an empirical study conducted to examine the relationship between employees’ Entrepreneurial, Professional, and Leadership (EPL) career motivations and their intrapreneurial motivation. Using data collected from 425 working adults in the research/innovation and healthcare settings, we develop a self-report measure of employee intrapreneurial motivation. We also adapt an existing self-report measure of E, P, and L career motivations (previously developed and used with university students) for use with working adult organizational employees. Confirmatory factor analysis indicate that E, P, and L motivations and intrapreneurial motivation can be measured independently and reliably, while regression analyses show that the employees’ E, P, and L motivations all contribute to explaining variance in their intrapreneurial motivation. Individuals with high E, P, and L motivational profiles are also found to have the highest intrapreneurial motivation scores, while those low on E, P, and L motivations have the least intrapreneurial motivation. Our findings suggest that the potential for intrapreneurship is not unique to only entrepreneurial employees. Instead, one can find intrapreneurs among employees with strong leadership and professional motivations as well. We discuss the findings in the context of generating more research to address the challenges of talent management in the 21st century knowledge economies where there is greater career mobility and boundarylessness in the workforce.

Item Parameter Estimation With the General Hyperbolic Cosine Ideal Point IRT Model

Over the last decade, researchers have come to recognize the benefits of ideal point item response theory (IRT) models for noncognitive measurement. Although most applied studies have utilized the Generalized Graded Unfolding Model (GGUM), many others have been developed. Most notably, David Andrich and colleagues published a series of papers comparing dominance and ideal point measurement perspectives, and they proposed ideal point models for dichotomous and polytomous single-stimulus responses, known as the Hyperbolic Cosine Model (HCM) and the General Hyperbolic Cosine Model (GHCM), respectively. These models have item response functions resembling the GGUM and its more constrained forms, but they are mathematically simpler. Despite the apparent impact of Andrich’s work on ensuing investigations, the HCM and GHCM have been largely overlooked by applied researchers. This may stem from questions about the compatibility of the parameter metric with other ideal point estimation and model-data fit software or seemingly unrealistic parameter estimates sometimes produced by the original joint maximum likelihood (JML) estimation software. Given the growing list of ideal point applications and variations in sample and scale characteristics, the authors believe these HCMs warrant renewed consideration. To address this need and overcome potential JML estimation difficulties, this study developed a marginal maximum likelihood (MML) estimation algorithm for the GHCM and explored parameter estimation requirements in a Monte Carlo study manipulating sample size, scale length, and data types. The authors found a sample size of 400 was adequate for parameter estimation and, in accordance with GGUM studies, estimation was superior in polytomous conditions.

Entrepreneurship in Singapore: Growth and Challenges

In this chapter, we provide a comprehensive and concise summary of recent entrepreneurial activities and attitudes in Singapore based on the 2012 Global Entrepreneurship Monitor (GEM) Singapore report (Chernyshenko et al. 2013). The 2012 GEM Singapore report included various key indicators of entrepreneurial activities and attitudes in Singapore in the prior year. Whenever available, we compare this recent survey with the 2011 and 2004–2006 surveys (Singapore did not participate in GEM survey between 2007 and 2010). Independent of the stage of economic development, entrepreneurship plays a significant role for the expansion, job creation, and overall economic health within a country (Shane 2008). Knowing the entrepreneurial aspirations of country’s residents is particularly relevant in Singapore’s innovation-driven economy given that the country’s prosperity depends largely on the economic activities of its citizens. This chapter on Singapore’s achievements and the challenges in promoting and understanding entrepreneurship may also provide some guidance and caution to other countries in the region and beyond.
