Third, a broad perspective calls for an open definition of elementary, analytical concepts and their relation to each other.
Here we present a global survey of erosion surfaces in mountain ranges and put existing theories and empirical evidence into a broad perspective calling for further research into the rates and regimes of long-term mountain evolution.
A complexity perspective calls for tolerance of ambiguity and an acceptance that not everything is knowable.
The North thus followed a forward-looking notion of equity and fairness, while developing countries reasoned from a largely historical perspective, calling for emissions in the past 200 years to be considered in distributing "allowed emission budgets".
Their high dynamicity and heterogeneity present significant challenges from the communications perspective, which call for the adoption of new paradigms based on opportunistic and Information-Centric Networking (ICN) approaches.
In sum, the fact that in all cases of this study the home as the central arena for safety and growth is affected, gives guidelines for future practices: since violence creates asymmetry, perspectives are called for that includes perspectives on both the child, and the adult exposed, and the abuser.
First, conventional 'hardware' notions of infrastructure arguably favour biomedical requirements for expensive instrumentation and technology; multidisciplinary health research centres incorporating social science perspectives may not call for comparable physical inputs.
This perspective would necessarily call for a reassessment of research and practice and may facilitate collaboration across disciplines (UNISDR 2015a, c).
In this Perspective, the authors call for an evidence-based discussion of the merits and challenges of three-year curricula.
Consistent with MacMillian et al. (2013) who take a close look at children's safety in domestic violence cases, and with Schacht et al. (2009), examining couple therapists' assessment practices, the present study tells that integrative family perspectives are called for, which combine violence- sensitivity with safety precautions, including the child's partaking voice and position.
