Received: 7 April 2010 Revised: 7 December 2010 Accepted: 13 December 2010 Abstract Studying knowledge strategy empirically requires that specific strategies be operationalized. In this paper, two existing knowledge strategy typologies (the Bierly & Chakrabarti typology of Loners, Explorers, Exploiters and Innovators and the von Krogh, Nonaka & Aben typology of Leveraging, Expanding, Appropriat...

The evolution of cooperation among nonrelated individuals is one of the fundamental problems in biology and social sciences. Reciprocal altruism fails to provide a solution if interactions are not repeated often enough or groups are too large. Punishment and reward can be very effective but require that defectors can be traced and identified. Here we present a simple but effective mechanism ope...

Mutualisms require protection from non-reciprocating exploiters. Pseudomyrmex workers that engage in an obligate defensive mutualism with Acacia hosts feed exclusively on the sucrose-free extrafloral nectar (EFN) that is secreted by their hosts, a behaviour linking ant energy supply directly to host performance and thus favouring reciprocating behaviour. We tested the hypothesis that Acacia hos...

The construction of reciprocal relationships requires cooperative interactions during the initial meetings. However, cooperative behavior with strangers is risky because the strangers may be exploiters. In this study, we show that people increase the likelihood of cooperativeness of strangers by using lightweight non-risky interactions in risky situations based on the analysis of a social netwo...

Abstract This study explores how an extreme far-right alternative media site uses content from professional to convey uncivil news with antisemitic message. Analytically, it rests on a critical discourse analysis of 231 items, originating established national and international sources, published Frihetskamp 2011–2018. In the study, we explore items are recontextualised portray both overt covert...

Some organisms maintain a battery of defensive strategies against their exploiters (predators, parasites or parasitoids), while others fail to employ a defence that seems obvious. In this paper, we shall investigate the circumstances under which defence strategies might be expected to evolve. Brood parasites and their hosts provide our main motivation, and we shall discuss why the reed warbler ...

The dynamics of undue influence (UI) have many similarities with domestic violence, stalking, and grooming behavior used by some sexual predators. This article will help practitioners-particularly law enforcement investigators and prosecutors-better recognize UI as a pattern of behaviors, not an isolated incident. Understanding the dynamics of UI will enhance professionals' appreciation of the ...

This paper identifies the critical learning trade-offs that managers face when defining their learning strategies. We integrate these learning choices into three configurations of learning strategies: " Explorers " , " Exploiters " , and " Innovators " , and address whether there is one optimal configuration of the learning tensions that leads to a superior learning strategy, or whether differe...

IGLECIA, MONICA N. Occupancy Models and Strategic Habitat Conservation for Avian Species in the Southeastern Coastal Plain of the United States. (Under the direction of Jaime A. Collazo). Rapidly expanding lists of priority species has increased the need for a framework that can utilize existing datasets to inform landscape-scale conservation strategies. This is evident in the South Atlantic Co...

Abstract The allocation of resources among different stakeholders is an ethical dilemma for chief executive officers (CEOs). In this study, we investigate the association between CEO power and workplace injuries illnesses. We use establishment-level dataset comprising 31,924 establishment-year observations 2002 2011. Our main result shows that employees at firms with structurally powerful CEOs ...
