Recent research on entrepreneurship has focused largely on macro-level environmental forces. Although researchers adopting this focus have rightly criticized much of the existing empirical research on the role of human motivation in entrepreneurship, we believe that the development of entrepreneurship theory requires consideration of the motivations of people making entrepreneurial decisions. To provide a road map for researchers interested in this area, we discuss the major motivations that prior researchers have suggested should influence the entrepreneurial process, as well as suggest some motivations that are less commonly studied in this area. In addition to outlining the major reasons for exploring these motivations, we identify the major weaknesses that have limited the predictive power of previous research on this topic. We offer explicit solutions for future research to adopt to overcome these problems.

A field study of top management teams and knowledge workers from 72 technology firms demonstrated that the rate of new product and service introduction was a function of organization members' ability to combine and exchange knowledge. We tested the following as bases of that ability: the existing knowledge of employees (their education levels and functional heterogeneity), knowledge from member ego networks (number of direct contacts and strength of ties), and organizational climates for risk taking and teamwork.

In this article, we begin to explore the black box between human resources (HR) practices and firm performance. Specifically, we examine the relationships between a set of network-building HR practices, aspects of the external and internal social networks of top management teams, and firm performance. Results from a field study with 73 high-technology firms showed that the relationships between the HR practices and firm performance (sales growth and stock growth) were mediated through their top managers' social networks.

Theory and research from the marketing literature on customer-based brand equity were used to predict how positive exposure to 4 early recruitment-related activities-publicity, sponsorships, word-of-mouth endorsements, and advertising-may affect the application decisions of engineering students. Similar to prior marketing findings, the results suggested that early recruitment-related activities were indirectly related to intentions and decisions through 2 dimensions of employer brand image: general attitudes toward the company and perceived job attributes. The relationships between word-of-mouth endorsements and the 2 dimensions of brand image were particularly strong. In addition, it was found that early recruitment-related activities interacted with one another such that employer brand image was stronger when firms used publicity in conjunction with other early recruitment-related activities.

Entrepreneurship is a major factor in the national economy; thus, it is important to understand the motivational characteristics spurring people to become entrepreneurs and why some are more successful than others. In this study, we conducted a meta-analysis of the relationship between achievement motivation and variables associated with entrepreneurial behavior. We found that achievement motivation was significantly correlated with both choice of an entrepreneurial career and entrepreneurial performance. Further, we found that both projective and self-report measures of achievement motivation were valid. Finally, known group studies yielded a higher validity coefficient than did individual difference studies.

The gravitational-wave signal GW190521 is consistent with a binary black hole (BBH) merger source at redshift 0.8 with unusually high component masses, M e and M e , compared to previously reported
