The main objective of this PhD Thesis is to go more deeply into the analysis and design of an intelligent system for surface roughness prediction and control in the end-milling machining process, based fundamentally on Bayesian network classifiers, with the aim of developing a methodology that makes easier the design of this type of systems. The system,whosepurpose is tomakepossible the surface...

This paper uses recent results from incentive theory to study heretofore informal critiques of piece-rate compensation schemes. The informal critiques are based on the history of failed attempts to install piece-rate compensation schemes at the turn of the century. The formal analysis empahsizes the importance of information and commitment in contracting. In particular, in a work environment ch...

Software use in many organizations has spread vertically as well as horizontally. This paper presents evidence that applications that are widely used in organizations have at least three distinct patterns of use: one for individual contributors, one for managers, and one for executives. Use within each of these groups is shaped by its particular activity and incentive structures. Interaction am...

The connections between female literacy rates, information technology and democracy are theoretically diverse and obscured by intervening economic and social factors. However, one should not overlook the important role of women’s education in the overall economic and political development of a country. This study focuses on the theoretical and statistical connections via a structured literature...

Contracting out is a policy that yields unambiguous fiscal gains to the governments that practise it . However, the majority these gains represent transfers from employees through reduced wages or increased work intensity. Some of these transfer losses are passed on to central governments through increased tax evasion. In this paper, the social costs and benefits of reductions in public sector ...
