Juvenile Cosmology; Or Richard Powers’ Post-Global Doughnut by Judith Roof

“…The novel’s collapse of time/space is not a simplistic paean to the global (a category already as out-dated as hapless Vietnam vets), but instead bags the gathering consciousness of an originless existence forever extending beyond its supposed coordinates. …”

Event-Based Consensus for General Linear Multiagent Systems under Switching Topologies by Yinshuang Sun, Zhijian Ji, Kaien Liu

“…First, centralised and decentralised event-triggered control strategies based on neighbors’ state estimation are proposed under fixed topology, in which the controller is only updated at the time of triggering. Obviously, compared with the continuous time control algorithms, the event-triggered control strategies can reduce the communication frequency among agents effectively. …”

The role, image and responsibilities of the midwife in Bohemia (19th and 20th Century) by Milena Lenderová

“… Following article reflects the social role, image and responsibilities of the midwives in Bohemia in the mid nineteenth up to the mid twentieth century, the period during which the position and image of the midwives significantly changed. In terms of time period the article analyses the time span when the professionalization of medicine is evolving to that extent that it begun also affect midwives: on the one hand, they remain personally connected with the female community and stand on the margin of the emerging obstetric science, on the other hand they became increasingly subject to official disciplinary authorities and regular inspections. …”
