Previous studies have been suggestive of the fact that reputation ratings may be provided in a strategic manner for reasons of reciprocation and retaliation, and therefore may not properly reflect the trustworthiness of rated parties. It thus appears that supporting privacy of feedback providers could improve the quality of their ratings. We argue that supporting perfect privacy in decentralize...

In current research stream, empirical work regarding knowledge hiding and reciprocal of along their dimensions is sparse. This study aims to partially fill this void by investigating the antecedents behavior i.e. social interaction ties, organizational culture self-referred fear (fear losing face, power isolation) on hiding. Further was also investigated as an outcome deployed quantitative meth...

From the COP （Coefficient of Performance） equation, there are two ways to improve cooling efficiency cryocoolers: （1） increasing capacity, and （2） decreasing electrical input power. In recent years, we have focused on possibility method for a 4 K-GM （Gifford-McMahon） cryocooler. this paper, 7 kW class compressor, which is commonly connected cold head, was replaced with low power consumption （2 cl...

Essential characteristics of corruption are (1) reciprocity relationships between bribers and public officials, (2) negative welfare effects, and (3) high penalties when discovered. We separate the influences of these factors in an experiment. In a two-player game reciprocation is economically inefficient through negative externalities. A control treatment without externalities is also conducte...

This paper considers why "rms often ban monetary exchange between their employees, while encouraging these trades through other means, such as through the reciprocation of favours or barter. Despite classical ine$ciencies associated with non-monetary exchange, we illustrate two themes as to why non-monetary trade may be preferred to allowing money. First, the use of non-monetary trade may a!ect...

Issues of fairness in hierarchies have been mostly investigated – both theoretically and experimentally – within dyadic principal–agent relationships. In this paper we consider triangular principal–multiagents structures, integrating vertical hierarchical relationships with horizontal agent–to–agent ones. We explore in the laboratory a game that allows to investigate how principal’s fairness af...

The distribution of bulk content such as video streams and system updates is becoming increasingly important on mobile devices. For this kind of data transfers, the application of the Peer-to-Peer (P2P) paradigm is attractive for content providers, as it allows to leverage clients’ (peers’) resources for the dissemination process. The contribution of resources can be encouraged by applying reci...

We interpret the reciprocation process in K[[x]] as a fixed point problem related to contractive functions for certain adequate ultrametric spaces. This allows us to give a dynamical interpretation of certain arithmetical triangles introduced herein. Later we recognize, as a special case of our construction, the so called Riordan group which is a device used in combinatorics. In this manner we ...
