Special issues as vertical integration: A rejoinder to Priem and Mowday

In this rejoinder to Priem and Mowday, the author amplifies and critiques some of their ideas on the proliferation of special issues in management journals. The author interprets special issues as vertical integration moves by journal editors operating in a context of perceived resource scarcity. He also argues that the proliferation of special issues is contributing to the...

Managing knowledge in organization studies through instrumentation

This article advocates a program of standard instrumentation in organization studies to improve the way knowledge is managed in the discipline. The construct ‘knowledge management’ is discussed, and the role of this construct in the theory of the firm is briefly reviewed. Then two problems of knowledge management in organization studies are identified—construct de-objectification and...

The value captor's process: getting the most of your new business ventures

The high failure rate among new business ventures is usually chalked up to the fundamental uncertainty of the process. In actuality, say McGrath and Keil, flawed ways of assessing and managing ventures may account for the disappointing amount of value they generate. Instead of taking the go/no-go approach, whereby a project either advances toward launch or is killed, decision makers...

Readout from iconic memory and selective spatial attention involve similar neural processes

Iconic memory and spatial attention are often considered separately, but they may have functional similarities. Here we provide functional magnetic resonance imaging evidence for some common underlying neural effects. Subjects judged three visual stimuli in one hemifield of a bilateral array comprising six stimuli. The relevant hemifield for partial report was indicated by an...

Spatial attention changes excitability of human visual cortex to direct stimulation

Conscious perception depends not only on sensory input, but also on attention [1, 2]. Recent studies in monkeys [3-6] and humans [7-12] suggest that influences of spatial attention on visual awareness may reflect top-down influences on excitability of visual cortex. Here we tested this specifically, by providing direct input into human visual cortex via cortical transcranial magnetic...

Learning-related human brain activations reflecting individual finances

A basic tenet of microeconomics suggests that the subjective value of financial gains decreases with increasing assets of individuals ("marginal utility"). Using concepts from learning theory and microeconomics, we assessed the capacity of financial rewards to elicit behavioral and neuronal changes during reward-predictive learning in participants with different financial...

Reward value coding distinct from risk attitude-related uncertainty coding in human reward systems

When deciding between different options, individuals are guided by the expected (mean) value of the different outcomes and by the associated degrees of uncertainty. We used functional magnetic resonance imaging to identify brain activations coding the key decision parameters of expected value (magnitude and probability) separately from uncertainty (statistical variance) of monetary...

Comparing risky and inter-temporal decisions: Views from psychology, ecology and microeconomics

When making decisions between different options, we often consider two basic properties of these options, how risky they are and when they will occur. For example, we may choose to gamble or to wait for a larger reward. Decisions under risk refer to decisions among known probabilistic options, inter-temporal decisions refer to choices between options that will be realized at known...
