Appropriate modelling of Likert-type items should account for the scale level and the specific role of the neutral middle category, which is present in most Likert-type items that are in common use. Powerful hierarchical models that account for both aspects are proposed. To avoid biased...

The optimization of decentralized energy systems is an important practical problem that can be modeled using stochastic programs and solved via their large-scale, deterministic equivalent formulations. Unfortunately, using this approach, even when leveraging a high degree of parallelism on large...

This study highlights the role of poverty factor in the explanation of child labor, by taking the work of Basu & Van (1999) as a theoretical basis. Thus, besides the search for the determinants of child labor by a multivariate approach, it tests the hypothesis of the luxury axiom which link...

BASED ON A SERIES OF SURVEYS ON THE LIVING AND MIGRATION CONDITIONS OF CHILDREN, THIS STUDY HIGHLIGHTS THE MAGNITUDE AND CHARACTERISTICS OF CHILD LABOUR IN BURKINA FASO, CÔTE D'IVOIRE AND MALI. FOUR (04) MAJOR LESSONS WERE LEARNT : (I) THE OVERWHELMING MAJORITY OF CHILDREN WORKING IN VIOLATION...

This paper proposes a sequential macroeconomic model to study investment complementarities in the presence of un(der)employment. It also incorporates some assumptions generally used in Keynesian economics like animal spirits, cash-in-advance constraints and irreversibility of investment...

The aim of this paper is to present selected models of a Software Development Life Cycle as a set of possible alternatives. The article also includes the characteristics of IT projects which are used as the basis for selection criteria, according to which an appropriate model should be chosen....

We discuss regression models for ordered responses, such as ratings of bonds, schooling attainment, or measures of subjective well-being. Commonly used models in this context are the ordered logit and ordered probit regression models. They are based on an underlying latent model with single...
