The limited evidence of effectiveness of existing teenage pregnancy strategies which focus on sex education, together with growing evidence that factors such as poor school ethos, disaffection, truancy, poor employment prospects and low expectations are associated with teenage pregnancy, has increased interest in interventions which target these “wider” social determinants. This paper aims to identify promising interventions and priorities for future research and to make recommendations for policy and practice in the UK.

This paper discusses the evidence regarding the potential of interventions which target determinants of teenage pregnancy relating to school disaffection and low expectations, drawing on recent systematic reviews and trials to consider future directions for research, policy and practice.

High‐quality research evidence illustrates the potential of two approaches to address determinants of teenage pregnancy relating to disaffection and low expectations. These are school‐ethos interventions, which aim to facilitate a positive and inclusive school‐ethos, strengthen school relationships and reduce disaffection; and targeted, intensive youth work interventions, which aim to promote positive expectations, vocational readiness and self‐esteem through vocational and life‐skills education, volunteering and work experience.

Two forms of intervention which address key social determinants of teenage pregnancy – school‐ethos interventions and targeted youth work interventions – require more attention from researchers and policy‐makers.

This paper calls for a shift in the research and policy agenda. In addition to interventions that aim to address proximal, individual factors, such as sexual health‐related knowledge, there should be a more complementary focus on socio‐environmental as well as targeted individual‐focused interventions aiming to address the wider social determinants of teenage pregnancy.

This paper proposes a new visco‐elastoplastic constitutive model for asphalt concretes able to reproduce the non linear time‐dependent behaviour of such materials.The constitutive model has been developed with the aim of making it fit specific experimental features previously observed. Moreover the proposed formulation will be demonstrated to be fully consistent with general thermodynamic requirements. Apart from a rigorous analytical formulation; a corresponding rheological sketch of the model is also given. From this representation, it can be shown that the model is essentially a combination of a generalized Maxwell model and a hardening visco‐plastic element.
