United Nations Educational, Scientific and Cultural Organization UNEP United Nations Environment Programme This report reflects the results of the UNESCO/UNEP project on “Youth, sustainable consumption and life styles”, which was launched in March 2000. The project was framed around a survey on the consumption patterns of young people in 24 countries and six country case studies. The results of...

The extent to which the presence of zoo visitors influences animal behavior, and the ways in which animal activity influences visitor interest and perception, are of great interest to zoological parks. Visitors have been variously characterized as being enriching for zoo animals, as being stressors, and generally as influencing behavior in measurable ways. Most studies have focused on primates,...

The Visitor pattern wraps associated operations that are performed on the elements of an object structure into a separate object. It allows the software designer to define new kinds of operations over the object structure without changing the classes of this structure. But a well-known drawback of this standard Visitor structure is that extending the object structure is hard. This paper present...

In process of software architecture design, different decisions with system-wide impacts are made. An important decision of design stage is the selection of appropriate software architecture style. Since quantitative impacts of styles on quality attributes have not been studied yet, their application is not systematic. Since Reliability is one of the essential quality requirements of software s...

BACKGROUND This study extends previous research (Dixon, Browne, & Hamilton-Giachritsis, 2004) by exploring the mediational properties of parenting styles and their relation to risk factors in the intergenerational cycle of child maltreatment. Families with newborns where at least one of the parents was physically and/or sexually abused as a child (AP families) were compared, in terms of parents...

Multiple dispatching and the visitor pattern are approaches to making object-oriented programs more extensible. Both have a flavor of pattern matching, thereby moving objectoriented programming closer to functional programming. The key idea of these approaches can be crystallized as a notion of visitor which lies between functions and objects. Can this idea be developed into a new form of visit...
