In order to authenticate non-existent resources, DNSSEC introduces NSEC-records [19] containing a linked-list of existing records ordered by name, hence actively denoting non-existing namespaces.
However useful to our research, publishing the complete list of available resources does not relate to the occasional request of non-existent resources and may even raise concerns on privacy.
Where DNSSEC so far authenticates existing resources, it is difficult to authenticate non-existing resources as non-existent records (1) have no corresponding signature, and (2) if for every NXDOMAIN response a signature would be computed online, key pairs would be more vulnerable to attacks.
Schools with poor or non-existent computer resources could link into the cloud-based system via smartphones or portable devices with internet connectivity.
Although insufficient financial remuneration had a negative impact on retention and performance, the main factors identified were limited opportunities for career development and further education (particularly for clinical officers) and inadequate or non-existent human resources management systems.
This cyclical effect of problems appeared to result from a combination of several factors, including staff shortages, poor supply systems, low or non-existent financial resources, and lack of regular professional development.
Although they are well-developed in high resource settings, they are almost non-existent in resource poor Low and Middle income countries (LMICs).
Education opportunities were almost non existent.
[are] practically non-existent, particularly in resource-poor settings.
Among the most striking results of this project were its impact on promoting physician cognitive screening and assessment, and engendering previously non-existent physician-community resource partnerships.
While these methods are a promising way of improving the reliability of DEA benchmarking, they are largely non-existent in lower resource settings such as Malaysia.
