Applicability and consequences of the integration of alternative models for CO2 transfer velocity into a process-based lake model

2019

Freshwater lakes are important in carbon cycling, especially in the boreal zone where many lakes are supersaturated with the greenhouse gas carbon dioxide (CO2) and emit it to the atmosphere, thus ventilating carbon originally fixed by the terrestrial system. The exchange of CO2 between water and the atmosphere is commonly estimated using simple wind-based parameterizations or models of gas transfer velocity (k). More complex surface renewal models, however, have been shown to yield more correct estimates of k in comparison with direct CO2 flux measurements. We incorporated four gas exchange models with different complexity into a vertical process-based physico-biochemical lake model, MyLak…

International opportunity recognition among small and medium-sized family firms

2011

Current research in the field of entrepreneurship emphasizes the importance of opportunity recognition as a key element in the entrepreneurial process. It has been recognized that network ties, activeness and alertness, and prior knowledge are related to how entrepreneurs recognize new opportunities. However, it is unclear how important these factors are when a firm explores opportunities for entry into a foreign market. In this exploratory case study, covering the international opportunity recognition of eight family-owned small and medium-sized enterprises (SMEs), we found that the firms in question mainly recognized international opportunities by establishing new formal ties rather than …

Additive manufacturing technology: Identifying value potential in additive manufacturing stakeholder groups and business networks

2015

The development of additive manufacturing (AM) technology is expected to transform product design and manufacturing. It is predicted that the effects of AM on business will be diverse and extensive. It will be critical for business owners to observe how AM impacts on conventional supply chains and business networks, plus the effects on customers’ value propositions and on value creation. Value creation and value capture are concepts strongly linked to business relations and to stakeholder management. However, the concept of value is inherently complex and multifaceted, and so are the structures within which value potential exists in business networks and business environments. The critical …
