This paper looks at interconnections between social, scientific, and technical time over the period since the Enlightenment. The underlying argument is that each of these can be woven into a single narrative of our experience and description of time over that period. In particular, I maintain that the synchronization of social and natural time into ever smaller, interchangeable units has culminated today in the evacuation of the narrative of progress in favor of an ideology of the eternal present. Contra technologically determinist characterizations that claim a fundamental historical disjuncture occurring with the development of computers, I claim that this timeless present has historical roots going back to the origin of industrial societies through the age of Victorian certainty to our current epoch. The multiple times described here are argued to be telling a single story. I demonstrate this through developing a historiographical principle of infrastructural inversion, which foregrounds a common set of "techniques dispositifs" operating in the apparently separate worlds of science and industry. The assertion here is that our experiences and perceptions of time are deeply imbricated in our information infrastructures. I further argue that these ideological charged times are not hegemonic; they merely describe a motivating managerial vision of a proximate future.

Rates and correlates of well-being among youth experiencing homelessness.

Mental health concerns have been well studied among youth experiencing homelessness, yet few studies have explored factors that contribute to well-being in this population. The current cross-sectional study examined rates and correlates of well-being among youth experiencing homelessness. This is a descriptive, secondary analysis of the baseline data from a clinical intervention study. Ninety-nine youth (aged 16-25) who were experiencing homelessness were recruited in Chicago. Approximately 40% of the sample reported average or above average well-being relative to existing benchmarks. Having medical insurance, a mobile phone, and a history of more severe childhood trauma were unique cross-sectional predictors of worse well-being (all ps < 0.034). A significant portion of our sample experienced well-being. Having access to certain resources may be counterintuitive indicators of poorer well-being among youth experiencing homelessness, perhaps because they are indicators of greater need or increased social comparison among these youth.

Investigating the Interoperable Health App Ecosystem at the Start of the 21st Century Cures Act.

The objective of this study was to investigate the state of the interoperable mobile health application (app) ecosystem at the start of the 21st Century Cures Act to understand the opportunities currently available to patients for accessing and using their computable clinical data. Thus, we sought to identify third-party apps in the Apple App and Google Play Stores that seem to be capable of automatically downloading clinical data via a FHIR-based application programming interface through a targeted review of health apps. We found that few of the apps in this review have this capability (1.4% of 1,272 iOS apps and 0.6% of 1,449 Android apps). Ultimately, our results suggest that this is a nascent marketspace. If barriers to app development are not identified and addressed, and efforts are not made to educate patients and improve discoverability of apps, it could mean that patients will not benefit from these interoperability measures.
