One of the main reasons that firms participate in alliances is to learn know-how and capabilities from their alliance partners. At the same time firms want to protect themselves from the opportunistic behavior of their partner to retain their own core proprietary assets. Most research has generally viewed the achievement of these objectives as mutually exclusive. In contrast, we provide empiric...

Systems that must plan, act, and probably learn using a rational, flexible behavior in real time present a challenge to current integrated schemas of planning and acting. Classical planning is still far from solving problems on such short time as needed in dynamic domains, such as Robosoccer, even with new approaches such as graph-based techniques. Reactive systems on the other hand, are hard t...

Do voters recognize opportunistic behavior? Do voters punish politicians identified as opportunistic even though their policies are responsible for the economic prosperity of pre-electoral times? If so, how big is the loss of votes related to that punishment? This paper addresses these questions and presents an empirical estimate regarding the voter’s direct response to opportunism. In particul...

Heterogeneous networked clusters are being increasingly used as platforms for resource-intensive parallel and distributed applications. The fundamental underlying idea is to provide large amounts of processing capacity over extended periods of time by harnessing the idle and available resources on the network in an opportunistic manner. In this paper we present the design, implementation and ev...

Networked organisations, consisting of enterprises who exchange things of economic value with each other, often have participants who commit a fraud or perform other actions, not agreed in a contract. To explore such opportunistic behaviour, and to design solutions to mitigate it, we propose the econtrol approach. This approach takes the valuable objects, which are exchanged between enterprises...

introduction : the decreased level of immunity in human immunodeficiency virus (hiv) infected patients increases their vulnerability to various opportunistic fungal infections. oral candidiasis has been found to be the most common fungal infection among hiv infected patients. the present study was conducted to evaluate the spectrum of various opportunistic fungal infections and their correlatio...

This paper discusses the role of opportunistic punisher who may act selfishly to free-ride cooperators or not to be exploited by defectors. To consider opportunistic punisher, we make a change to the sequence of one-shot public good game; instead of putting action choice first before punishment, the commitment of punishment is declared first before choosing the action of each participant. In th...

In this paper, we study the spectrum assignment problem for wireless access networks. Opportunistic spectrum usage is a promising technology. However, it could suffer from the selfish behavior of secondary users. In order to improve opportunistic spectrum usage, we propose to combine the game theory with wireless modeling. Several versions of problems are formalized under different assumptions....

A model of unrestricted And-parallel execution for logic programs is described, based on Dependency Directed Backtracking (DDBT) aimed at improving the efficiency of execution while remaining faithful to conventional syntax and semantics. This is achieved with maximum exploitation of parallelism, DDBT, support of opportunistic stream parallelism and potentially parallel backtracking. The same d...

We use a large and unique administrative dataset from Italy, covering the period 2009-2014, to investigate opportunistic behavior (moral hazard) and the effectiveness of monitoring policies related to insurance against illness-related income losses. The analysis is based on the outcome of mandatory medical visits aimed at verifying the health status of employees during sickness spells. We find ...
