“…In a series of NIH-funded projects in the 1990s, research was conducted on new ways to organize and give access to cancer information for both clinicians and consumers ( Crangle et al, 1996a ; Crangle et al, 1996b ; Crangle et al, 1998a ; Crangle et al, 1998b ; Tuttle et al, 1996 ). An interesting discovery was that systems designed for clinicians had to be adapted because consumer questions were different from clinical questions in important ways.…”

Despite the wealth of mental-health information available online to consumers, research has shown that the mental-health information needs of consumers are not being met. This study contributes to that research by soliciting consumer questions directly, categorizing them, analyzing their form, and assessing the extent to which they can be answered from a trusted and vetted source of online information, namely the website of the US National Institute of Mental Health (NIMH). As an alternative to surveys and analyses of online activity, this study shows how consumer questions provide new insight into what consumers do not know and how they express their information needs. The study crowdsourced 100 consumer questions through Amazon Inc.'s Mechanical Turk. Categorization of the questions shows broad agreement with earlier studies in terms of the content of consumer questions. It also suggests that consumers' grasp of mental health issues may be low compared to other health topics. The majority of the questions (74%) were simple in form, with the remainder being multi-part, multifaceted or narrative. Even simple-form questions could, however, have complex interpretations. Fifty four questions were submitted to the search box at the NIMH website. For 32 questions, no answer could be found in the top one to three documents returned. Inadequacies in the search and retrieval technology deployed at websites account for some of the failure to find answers. The nature of consumer questions in mental health also plays a role. A question that has a false presupposition is less likely to have an answer in trusted and vetted sources of information. Consumer questions are also expressed with a degree of specificity that makes the retrieval of relevant information difficult. The significance of this study is that it shows what an analysis of consumer mental-health questions can tell us about consumer information needs and it provides new insight into the difficulties facing consumers looking for answers to their questions in online resources.

This paper describes mathematical models of off-nominal events and the corresponding mitigation strategies in Super Density Operations. Research in mitigation strategies focuses on procedural and algorithmic solutions to mitigating the off-nominal condition and returning the system back to the nominal state when it is feasible to do so. Mitigation strategies investigated in this paper include use of flexible airspace to perform path stretching and reroutes, placement of holding patterns, as well as speed control to open gaps in streams of aircraft. We also describe a computation framework developed to conduct analysis of off-nominal conditions and report results of initial simulation studies demonstrating the feasibility of the developed approach.

Maintaining and supporting complex systems within a developing world context has many challenges including dealing with systems that are being operated beyond their designed life or where obsolescence is a major concern. Current methodologies to develop an integrated logistics support system (ILSS) are based on assumptions that are not valid in all cases, and a more robust framework with grounded design rules is required.The approach followed in developing the grounded technological rules was by deconstructing the available ILSS and related literature six case studies into the a framework. After analysis of this qualitative work, a third phase was added on where a questionnaire was used to explore the key areas of concern. Some of the insights regarding obsolete and beyond life complex systems were found to be: the effect of obsolescence is significantly wider than the obsolescence and retirement element of the existing frameworks; obsolescence planning must be done on reliability data for the specific operating environment, it is essential to understand technological changes and scan continuously for the impact on system or component obsolescence and that a risk based approach is essential to develop a obsolescence plan as part of the ILSS.
