On Rob Kling: The Theoretical, the Methodological, and the Critical

We explore Rob Kling’s conceptual scaffolding for Social Informatics: his integration of theory, method and evidence and philosophical underpinnings and moral basis of his commitment to a critical stance towards computers and social life. He extended his focus on organizational practices and a lifelong meditation on democracy, value conflicts and social choices to the discourses of computerization and social transformation and to the education of the information professional. He came to his project through careful observation of organizational life and a critical reading of research conducted by other scholars and the rhetoric about ICTs, As Kling conceptualized it, the project of Social Informatics was to intervene in the social construction of the meaning, value, use and even design of technologies as shaped by discourse and education.Indiana Universit

Social Informatics Education in I-Schools

This essay focuses on the philosophical and conceptual underpinnings of a program of study in Social Informatics. We examine foundational concepts and analytical tools, ideas worked out by Rob Kling and others about the key components of an ICToriented education (even when the intent of their discussion was not pedagogical). Our intention is to assay Kling’s program of critical inquiry for a Social Informatics education that prepares information professionals to respond appropriately and ethically in their future careers. We do not to recommend the adoption of specific courses for a Social Informatics education. We had also planned to identify those components of a Social Informatics education that I-schools and library and information science schools have incorporated in their program offerings to determine how much progress has been made to adopt a critical perspective on the relationship between technology and people. However, this proved to be nearly impossible; we discuss our limited findings based on our initial exploration. Our concluding remarks address additions to the Kling perspective on a Social Informatics education that we would like to see and offer some thoughts on ways to support a Social Informatics education for information professionals.Indiana Universit

First Constraints on Compact Dark Matter from Fast Radio Burst Microstructure

Despite existing constraints, it remains possible that up to $35\%$ of all dark matter is comprised of compact objects, such as the black holes in the 10-100\,M$_\odot$ range whose existence has been confirmed by LIGO. The strong gravitational lensing of transients such as FRBs and GRBs has been suggested as a more sensitive probe for compact dark matter than intensity fluctuations observed in microlensing experiments. Recently ASKAP has reported burst substructure down to $15\mu$s timescales in FRBs in the redshift range $0.3-0.5$. We investigate here the implications of this for the detectability of compact dark matter by FRBs. We find that a sample size of $\sim130$ FRBs would be required to constrain compact dark matter to less than the existing 35$\%$ limit with 95$\%$ confidence, if it were distributed along $\gtrsim 1\,$Gpc-long FRB sightlines through the cosmic web. Conversely, existing constraints on the fraction of compact dark matter permit as many as 1 in $\approx 40$ of all $z \lesssim 0.4$ FRBs to exhibit micro-lensed burst structure. Approximately $170$ FRBs intercepting halos within $\sim 50\,$kpc would be required to exclude the fraction of compact dark matter in each intercepted halo to a similar level. Furthermore, we consider the cumulative effects of lensing of the FRB signal by a macroscopic dark matter distribution. We conclude that lensing from a uniform distribution of compact objects is likely not observable, but suggest that FRBs may set meaningful limits on power-law distributions of dark matter.Comment: 3 Figures, 1 tabl

Pathogenesis of non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease (NAFLD) represents a spectrum of disease ranging from hepatocellular steatosis through steatohepatitis to fibrosis and irreversible cirrhosis. The prevalence of NAFLD has risen rapidly in parallel with the dramatic rise in obesity and diabetes, and is rapidly becoming the most common cause of liver disease in Western countries. Indeed, NAFLD is now recognized to be the aetiology in many cases previously labelled as cryptogenic cirrhosis
