白音查干矿井涌水量预计

矿井涌水量计算是矿床水文地质勘查中一项重要而复杂的工作,也是矿床水文地质勘查中的根本任务之一。运用大井法和廊道法对首采区、首采工作面和开切眼涌水量进行了预计,认为大井法计算的涌水量成果较为可靠,矿井最大涌水量为296.80m3/h,为今后的矿井安全生产提供了理论依据。

Managing digital business platforms: A continued exercise in balancing renewal and refinement

Central to the evolution of a digital business platform is the organization’s ability to balance exploration (renewal) and exploitation (refinement) simultaneously. Drawing on prior research—including digital platforms, contradictory tensions, and organizational ambidexterity—and our own experience investigating digital business platforms in organizations, this article provides insights into how executives can manage this evolution successfully. More specifically, we present a framework recognizing three pairs of organizational capabilities (i.e., identifying-nourishing, expanding-legitimating, and augmenting-embedding) that enable balancing renewal and refinement of the platform over time. We close by providing critical managerial practices that executives can use in anticipating, adjusting, and evaluating the evolution of a digital business platform over time, including its initiation, development, and growth.     

Microfoundations of network exploration and exploitation capabilities in international opportunity recognition

While international entrepreneurship (IE) recognizes opportunity recognition (OR) as a central activity and the prominent role of network capabilities in OR, it is not informative as to how different network capabilities influence OR in international markets. We utilize dual network capability through the lens of exploration-exploitation to better understand how these two different capabilities influence the identification of international opportunities. Given that microfoundations perspective and prior experience in IE are under-developed and under-theorized, we explore founder’s prior experience as an essential microfoundation for the dual network capability. By employing structural equation modeling on a sample of 647 early internationalizing firms from a developing country, the study demonstrates that founders’ prior experience is a significant microfoundation of dual network capability in international OR. However, both exploration and exploitation capabilities fail to bring new opportunities in a changing market environment. A post-hoc analysis reveals that at a higher level of market change, younger firms benefit more from network exploration, whereas older firms achieve greater success when leveraging benefits from network exploitation. The study concludes with implications and future research avenues.     

How knowledge flow affects Korean ICT manufacturing firm performance: a focus on open innovation strategy

The paper presents an integrated viewpoint of technological innovation strategy by considering both the firm and industry levels. Further, we provide a new open innovation framework by adopting a knowledge flow perspective using patent citation information. Finally, we consider a firm’s outbound open innovation performance using cites per patent information together with financial performance to look at both the practical and the potential effects of technological innovation strategy. Through these analyses, this study examines determinants of open technology innovation activity in the information and communication technology manufacturing industry in Korea and draws managerial and policy implications for effective industry promotion and improvement of technology innovation capability.

Marx,Sraffa, and Surplus: Observations Prompted by Garegnani (2018)

ABSTRACT

In a posthumously published article, Pierangelo Garegnani (2018. ‘On the Labour Theory of Value in Marx and in the Marxist Tradition.’) depicts Marx’s project in Capital as that of ‘developing systematically the theory of Ricardo and [the] implications of social conflict’ implied by Ricardo’s ‘surplus approach to value and distribution’. This paper argues to the contrary that Marx’s theory of surplus value and exploitation differs from (neo-)Ricardian surplus theory in fundamental ways, and modifies Garegnani’s simple Sraffian model to illustrate the distinctive implications of Marx’s theory.     

Trading off learning and performance: Exploration and exploitation at work

Employees are increasingly given control over how they learn, and their choices for training are diverse and varied, yet employees must balance competing demands. On one hand, they are expected to be increasingly efficient in their current job duties – on the other hand, they are expected to develop new skills and competencies that enable them to adapt and respond to changing job demands. Drawing from the organizational learning literature, we propose a model of worker and work characteristics that inform choices between two mindsets related to learning at work. The first mindset is exploration, or the pursuit of learning outside one’s current knowledge domain; the second mindset is exploitation, the refinement/deepening of one’s existing knowledge stock focusing on the task at hand. We further propose that these strategic choices, or trade-offs, influence employee learning and performance in unique ways, with different implications for both routine and adaptive performance. Finally, we incorporate the notions of feedback loops and risk assessments that influence ongoing decisions between exploration and exploitation mindsets. Recommendations for future research and extensions of the theoretical model are also proposed.
