Scale horizons in analytic hierarchies

In the light of the many criticisms to which the analytic hierarchy process (AHP) of Saaty has been subjected, the authors have produced a refined version, the modified analytic hierarchy process. This paper develops further the ideas behind the modified process and illustrates with examples some of the difficulties in the AHP and their resolution.     

The Ethics of Germline Gene Editing

Germline Gene Editing (GGE) has enormous potential both as a research tool and a therapeutic intervention. While other types of gene editing are relatively uncontroversial, GGE has been strongly resisted. In this article, we analyse the ethical arguments for and against pursuing GGE by allowing and funding its development. We argue there is a strong case for pursuing GGE for the prevention of disease. We then examine objections that have been raised against pursuing GGE and argue that these fail. We conclude that the moral case in favour of pursuing GGE is stronger than the case against. This suggests that pursuing GGE is morally permissible and indeed morally desirable.     

Is the igeneration a ‘we’ generation? Social networking use among 9‐ to 13‐year‐olds and belonging

Research suggests that online communication is associated with increased closeness to friends and friendship quality. Children under 13 years of age are increasingly using social networking sites (SNSs), but research with this younger age group is scarce. This study examined the relationship between SNS use and feelings of belonging among children aged 9–13 years. A self‐report questionnaire was administered to 443 children (48.98% boys), asking about their SNS use and their sense of belonging to their friendship group. SNS users reported a stronger sense of belonging to their friendship group than non‐users, but this was found only among older boys. Furthermore, among boy SNS users, a positive linear relationship was found between the intensity of usage and feelings of belonging. No significant relationships were found for girls. These findings suggest that boys who use these sites are gaining friendship benefits over and above those boys who are non‐users or low‐intensity users. Longitudinal studies should investigate the causal relationships between SNS use and social effects within this age group.
