Policy Abstract Quantitative modelling is commonly used to assist the policy dimension of sustainability problems.

Validation is an important step to make models credible and useful. To investigate existing validation viewpoints and approaches, we analyse a broad academic literature and conduct a survey among practitioners.

We find that empirical data plays an important role in the validation practice in all main areas of sustainability science. Qualitative and participatory approaches that can enhance usefulness and public reliability ethics codes tend to be: much less visible. Data-oriented validation is prevalent even when models are used for scenario exploration. Usefulness regarding a given task is more important for model developers than for users.

These findings provide a reflection on current validation practices and are expected to facilitate communication at the modelling and decision-making interface.

Download PDF Introduction Quantitative modelling is an essential component of socio-environmental and economic research, management and policymaking. A broad range of models, including ethics codes tend to be: assessment models, impact assessment models, environmental models, systems models, and so forth, address resource management problems in various areas related to sustainability, from ecosystems to energy systems.

Some of these models have a prescriptive stance, generating recommendations for action. Others aid decision-making in different ways, for example with long-term projections, while capturing the complexity of various physical, economic and social factors.

Standing at the intersection of environmental science, economics and decision sciences, such modelling studies have resulted in influential applications, such as the large modelling framework used by the European Commission for the impact assessment of energy and environmental policies 123or the National Energy Modelling System NEMS of the US Energy Information Administration 4. The credibility of ethics codes tend to be: projections generated by quantitative models has been the topic of a heated debate.

Exam (elaborations)

ethics codes tend to be: Several critiques in the academic literature and popular media outlets highlighted that models are typically used as if they are precise predictors, and uncertainties are ignored 567 ; that the methods used to deal with uncertainties are often inadequate or unsuitable 8910 ; that models routinely extrapolate past data as if it is a good estimate of the future 1112 ; and that models usually have a limited scope, and often omit relevant and important processes 11 Validation is the modelling step commonly employed to deal with such criticism and to establish a sound grounding for models at the science-policy interface.

The definition of validation is equivocal across different scientific fields. In decision sciences, validation usually implies establishing confidence in the model by judging its usefulness with respect to some purpose 14 In environmental modelling, validity is often used to indicate that ethics codes tend to be: predictions are consistent with observational data, or that the model is an accurate representation of physical reality, or both 1617 We do not refer only to the representation accuracy, but we imply establishing confidence in the model by employing a variety of assessment tools. These different connotations to the term validation stem from different philosophies of science.

The benefits of buying summaries with Stuvia:

Positivism and relativism are often stated as the two distinct philosophies of science underlying the validation viewpoints 1820 Being rooted in logical empiricism, which argues that knowledge is acquired by observational data and the interpretation thereof through logic and reason, positivist validation approaches focus on an accurate representation of reality and employ statistical tests to compare the model output and the data. The positivist viewpoint on validation reflects the practice in natural sciences. Alternatively, the relativist view on validation originates from the challenge Thomas Kuhn posed on the objectivity assumption in positivism, that is, scientific knowledge is relative since it depends on the paradigm prevalent at the time of a study. The article source validation approaches value the model usefulness, for instance in the sense of fitness for purpose, more than the representation accuracy and employ semiformal and conversational tools.

In decision sciences, economics, and management science, validation ethics codes tend to be: cover both of these philosophical viewpoints 20 Practitioners often acknowledge the value of both, and employ a combination of multiple validation techniques ethics codes tend to be:

Probably not. But good news: you can change this. Issue 68, 31st July A. When their mother heard their cries, she and several other family members dove into the ocean, only to be trapped in the current, too. Then, in a powerful display of character, complete strangers on the beach took action. Forming a human chain of 70 to 80 bodies , they stretched out into the ocean and rescued everyone. Stories like this inspire me with hope about what human beings are capable of doing. Though we may face a daily barrage of depressing reports about sexual harassment, corruption, and child abuse, stories of human goodness help to give us another perspective on our human character. But, as we know too well, there is also a darker side to our character. Take, for example, the story of Walter Vance , 61, who was shopping in his local Target for Christmas decorations.
