This paper aimed to look for the existence of a common core when envisaging intra-familial interactions as perceived by adolescents, which could be shared by sociology, psychoanalysis and child and adolescent psychiatry. An empirical study based on a mixed-method design collected the responses of 194 adolescents to the instruction "In the next half hour, would you please write as freely as you ...

A plant has more flexibility in choosing among different technologies before undertaking an investment than after installing a specific machine. This paper argues that the irreversibility of factor intensity choice may play an important role in explaining the dynamics of investment in the presence of relative factor price uncertainty. A higher degree of irreversibility in the choice of factor i...

Using factor methods, we decompose industrial production (IP) into components arising from aggregate and sector-specific shocks. An approximate factor model finds that nearly all of IP variability is associated with common factors. We then use a multisector growth model to adjust for the effects of input-output linkages in the factor analysis. Thus, a structural factor analysis indicates that t...

1. Traditional approaches to irony Here are some typical examples of verbal irony: (1) Mary (after a boring party): That was fun. (2) I left my bag in the restaurant, and someone kindly walked off with it. (3) Sue (to someone who has done her a disservice): I can't thank you enough. In each case, the point of the irony is to indicate that a proposition the speaker might otherwise be taken to en...

This paper will introduce the topic of dynamical systems with both discrete and continuous time variables. Fixed points will be discussed, along with their properties such as stability or topological type. The paper will continue on to define the concept of hyperbolicity and its relevance in determining the structural stability of the system. It will conclude with a definition of a bifurcation ...

Emotions and cognition are inextricably intertwined. Feelings influence thoughts and actions, which in turn can give rise to new emotional reactions. We claim that people infer emotional states in others using commonsense psychological theories of the interactions among emotions, cognition, and action. We present a situation calculus theory of emotion elicitation representing knowledge underlyi...

Orthodontic treatment is routinely described to last, on average, 24 months. Nonetheless, every orthodontist has already experienced that this time length shows huge variability, depending on several factors that are inherent to the operator, the patient, scientific knowledge and mastering of the mechanics used in orthodontic movement. It is very likely that there is something else, something s...

Lazy clause generation is a powerful approach to reducing search in constraint programming. For use in a lazy clause generation solver, global constraints must be extended to explain themselves. Alternatively they can be decomposed into simpler constraints which already have explanation capability. In this paper we examine different propagation mechanisms for the alldifferent constraint, and sh...
