Are We Wise About Sub-Fields in IS? Lessons from Forming and Sustaining a Research Community

Sub-fields within I.S. generate benefits for their participants and for the larger research discipline. Sub-fields can also fragment and compete with the broad field they emerge from. One of the largest and most active research groups in the ICIS community is the researchers examining Information Systems Economics. After 20 years of the Workshop on Information Systems and Economics (WISE), this is a moment to identify what sub-fields contribute in I.S. and look forward to what sub-fields can do for ICIS researchers and I.S. practice in the future

Sharing Logistics Information Across Organizations: Technology, Competition and Contracting

Information technology has altered the way companies manage their supply chains, and has resulted in a variety of new inter-organizational logistics management approaches. Many partners who are adjacent on the supply chain can both gain from sharing information that was previously accessible to only one of them; this situation is typical in retailer-supplier interactions. Our study analyzes these different kinds of virtually integrated corporations — independent companies which operate somewhat like a single vertically integrated firm — and classify them based on the impact that the information shared has on the contracting parties. We find that there are four primary levels at which firms can share information. We then investigate how competition and contracting affect the nature of value sharing at each of these levels. Our results indicate that retailers and other buyers can successfully contract to end up with more value than is generated by the sharing of information, and that if the possibility of information sharing exists, then suppliers will end up worse off than before. Using game-theoretic models of strategic interaction, we show that this effect intensifies as the competitive value of the information to the supplier increases--paradoxically, as the value generated by a supplier from information sharing increases, the supplier loses more and more value. Furthermore, we demonstrate that in order to extract the competitive value of information from a supplier, the buyer need not actually share the information; the possibility of sharing is sufficient, even when the buyer cannot create value from that information. We also analyze the effects of other factors such as technology costs and demand uncertainty on these information sharing contracts. Finally, we show that the a critical predictor of the level of information sharing between companies is their relative positions on the supply chain, and that the drivers of the level chosen are relative bargaining power and potential agency costs

DNA virus BdDV-1 of the amphibian pathogen Batrachochytrium dendrobatidis is associated with hypervirulence

The Global Panzootic Lineage (GPL) of the pathogenic fungus Batrachochytrium dendrobatidis ( Bd ) has caused severe amphibian population declines, yet the drivers underlying the high frequency of GPL in regions of amphibian decline are unclear. Using publicly available Bd genome sequences, we identified multiple non-GPL Bd isolates that contain a circular Rep-encoding single stranded DNA-like virus which we named BdDV-1. We further sequenced and constructed genome assemblies with long read sequences to find that the virus is likely integrated into the nuclear genome. Attempts to cure virus positive isolates were unsuccessful, however, phenotypic differences between naturally virus positive and virus negative Bd isolates suggested that BdDV-1 decreases the growth of its host in vitro but increases the virulence of its host in vivo . BdDV-1 is the first described CRESS DNA mycovirus to increase host virulence with a distribution inversely associated with the emergence of the panzootic lineage

An endogenous DNA virus in an amphibian-killing fungus associated with pathogen genotype and virulence

The global panzootic lineage (GPL) of the pathogenic fungus Batrachochytrium dendrobatidis (Bd) has caused severe amphibian population declines, yet the drivers underlying the high frequency of GPL in regions of amphibian decline are unclear. Using publicly available Bd genome sequences, we identified multiple non-GPL Bd isolates that contain a circular Rep-encoding single-stranded (CRESS)-like DNA virus, which we named Bd DNA virus 1 (BdDV-1). We further sequenced and constructed genome assemblies with long read sequences to find that the virus is integrated into the nuclear genome in some strains. Attempts to cure virus-positive isolates were unsuccessful; however, phenotypic differences between naturally virus-positive and virus-negative Bd isolates suggested that BdDV-1 decreases the growth of its host in vitro but increases the virulence of its host in vivo. BdDV-1 is the first-described CRESS DNA mycovirus of zoosporic true fungi, with a distribution inversely associated with the emergence of the panzootic lineage
