This commentary explores the nature of creating safety in the here-and-now. Creating safety encompasses two dimensions: revisiting specific behaviours by focusing on substandard performance (reflection), and a more broad-ranging attention to everyday behaviours that are taken as given (reflexivity). The piece pays particular attention to this second dimension of creating safety. Two techniques ...

Composition of Web Services (WSs) is anticipated as the future standard way to dynamically build distributed applications, and hence their veri cation and validation is attracting great attention. The standardization of BPEL as a composition language and of WSDL as a WS interface de nition language has led researchers to investigate veri cation and validation techniques mainly focusing on the s...

Testing and code editing are interleaved activities during program development. When tests fail unexpectedly, the changes that caused the failure are not always easy to find. Change classification focuses programmer attention on those changes most likely to be failure-inducing. We define several classifiers that automatically label changes as Red, Yellow, or Green, indicating the likelihood tha...

Optimisation problems in Healthcare have received considerable attention for more than three decades. More recently, however, with decreasing birth rates in nearly all of the developed countries and increasing average longevity globally, optimisation issues in Healthcare have become noticeably important and attract keen interest from the Operations Research community. Over the years, attention ...

Remote sensing research focusing on feature selection has long attracted the attention of the remote sensing community because feature selection is a prerequisite for image processing and various applications. Different feature selection methods have been proposed to improve the classification accuracy. They vary from basic search techniques to clonal selections, and various optimal criteria ha...
