Mechanisms for the formation and disappearance of the crack‐like pores generated during the early stage of Al foaming are investigated. A model for their disappearance process is proposed for the first time. The stress, perpendicular to the compaction direction in uniaxial cold compaction, is caused by the interaction of the Al powder under a high compaction pressure and is the main reason for the formation of the crack‐like pores. The results of the model analysis and theoretical calculations suggest that the pressure difference ΔP between the initial, round bubbles and the crack‐like pores is the driving force for their disappearance. The rapid reduction of ΔP is attributed to the decomposition characteristics of the TiH2 powder.

This article maintains that the consistent application of subjectivism helps reconcile contemporary entrepreneurship theory with the strategic management literature, particularly the resource-based view of the fi rm. The article synthesizes theoretical insights from Austrian economics, Penrose's (1959) resources approach, and modern resource-based theory, focusing on the essential subjectivity of the entrepreneurial process. This new synthesis describes entrepreneurship as a creative team act in which heterogeneous managerial mental models interact to create and arrange resources to produce a collective output that is creatively superior to individual output.

COVID-19’s impacts on workers and workplaces across the globe have been dramatic. This broad review of prior research rooted in work and organizational psychology, and related fields, is intended to make sense of the implications for employees, teams, and work organizations. This review and preview of relevant literatures focuses on: (i) emergent changes in work practices (e.g., working from home, virtual teamwork) and (ii) emergent changes for workers (e.g, social distancing, stress, and unemployment). In addition, potential moderating factors (demographic characteristics, individual differences, and organizational norms) are examined given the likelihood that COVID-19 will generate disparate effects. This broad-scope overview provides an integrative approach for considering the implications of COVID-19 for work, workers, and organizations while also identifying issues for future research and insights to inform solutions.

This paper explores innovation, experimentation, and creativity in the public domain and in the public interest. Researchers in various disciplines have studied public entrepreneurship, but there is little work in management and economics on the nature, incentives, constraints, and boundaries of entrepreneurship directed to public ends. We identify a framework for analyzing public entrepreneurship and its relationship to private entrepreneurial behavior. We submit that public and private entrepreneurship share essential features but differ critically regarding the definition and measurement of objectives, the nature of the selection environment, and the opportunities for rent seeking. We describe four levels of analysis for studying public entrepreneurship, provide examples, and suggest new research directions.

We analyse the relationship between firm value, as measured by Tobin's q, and newly released indices of effective corporate governance for a sample of 263 Canadian firms. The results indicate that corporate governance does matter in Canada. However, not all elements of measured governance are important, and the effects of governance do differ by ownership category. For the entire sample of firms we find no evidence that a total governance index affects firm performance. This is mainly because we find no evidence that board independence, the most heavily-weighted sub-index, has any positive effect on firm performance. Indeed, for family-owned firms we find that the effect is negative. In general, sub-indices measuring effective compensation, disclosure and shareholder rights practices enhance performance and this is true for most ownership types. We also find no evidence that governance practices are endogenous. Copyright Blackwell Publishing Ltd 2005.

Entrepreneurship, long neglected by economists and management scholars, has made a dramatic comeback in the last two decades, not only among academic economists and management scholars, but also among policymakers, educators and practitioners. Likewise, the economic theory of the firm, building on Ronald Coase's (1937) seminal analysis, has become an increasingly important field in economics and management. Despite this resurgence, there is still little connection between the entrepreneurship literature and the literature on the firm, both in academia and in management practice. This book fills this gap by proposing and developing an entrepreneurial theory of the firm that focuses on the connections between entrepreneurship and management. Drawing on insights from Austrian economics, it describes entrepreneurship as judgmental decision made under uncertainty, showing how judgment is the driving force of the market economy and the key to understanding firm performance and organization.
