Birth is the most common reason for hospitalization in the United States. Hospital variation in maternal outcomes is an important indicator of health care quality. Spontaneous vaginal birth (SVB) is the most optimal birth outcome for the majority of mothers and newborns. The purpose of this study was to examine hospital-level variation in SVB overall and among low-risk women in a four-state sample representing 25% of births in the United States in 2016.
 
  Women giving birth in California, Pennsylvania, New Jersey, and Florida were identified in 2016 state discharge abstracts. Patient data were merged with hospital data from the American Hospital Association's (AHA) 2016 Annual Survey. Overall and low-risk SVB rates were calculated for each hospital in the sample and stratified by bed size, teaching status, rurality, birth volume, and state.
 
  Our final sample included 869 681 women who gave birth in 494 hospitals. The mean overall SVB rate in the sample was 61.1%, ranging from 16.8% to 79.9%. The mean low-risk SVB rate was 78% and ranged from 34.6% to 93.3%. Variation in SVB rates cut across all the hospital structural characteristic strata.
 
  The wide variation in SVB rates indicates significant room for improvement in this maternal quality metric. Our finding, that hospitals of all types and locations had both low and high SVB rates, suggests that excellent maternal outcomes are possible in all hospital settings. The variation in SVB rates across hospitals warrants research into modifiable hospital factors that may be influencing SVB rates.

Nevertheless, the role of β3-ARs in the cerebellum has been never investigated. To address this issue, we first examined the effects of pharmacological manipulation of β3-ARs on motor learning in mice. We found that blockade of β3-ARs by SR 59230A impaired the acquisition of the rotarod task with no effect on general locomotion. Since the parallel fiber-Purkinje cell (PF-PC) synapse is considered to be the main cerebellar locus of motor learning, we assessed β3-AR modulatory action on this synapse as well as its expression in cerebellar slices. We demonstrate, for the first time, a strong expression of β3-ARs on Purkinje cell soma and dendrites. In addition, whole-cell patch-clamp recordings revealed that bath application of β3-AR agonist CL316,243 depressed the PF-PC excitatory postsynaptic currents via a postsynaptic mechanism mediated by the PI3K signaling pathway. Application of CL316,243 also interfered with the expression of PF long-term potentiation, whereas SR 59230A prevented the induction of LTD at PF-PC synapse. These results underline the critical role of β3-AR on cerebellar synaptic transmission and plasticity and provide a new mechanism for adrenergic modulation of motor learning.
  The primary aim of this study was to examine the effectiveness of the blended learning pedagogy in a clinical skill-based module using the Community of Inquiry (CoI) framework. The secondary objectives were to assess the effectiveness of blended learning in improving the nursing knowledge, and students' satisfaction with this approach.
 
  Blended learning is increasingly adopted in education as more online resources are made available for tutors to use for the benefit of their students. That implied a reduction in the face-to-face contact time in replacement for online teaching, which therefore warrants a need to examine the effectiveness of blended learning approach. The application of CoI framework could evaluate the blended learning approach to assist teaching faculty with evidence-based practices on online teaching.
 
  This study used the quasi-experimental, pretest-posttest design, and results were presented according to the Transparent Reporting of Evaluations with Nonrandomised Designs (TREND) guidelines.
 
  This study was conducted in a university and recruited 219 Year 1 nursing students who completed a clinical-based module.
 
  The results of the CoI survey found that teaching presence scored the highest mean, followed by cognitive and social presence. The design of the blended learning was effective in enhancing students' knowledge but they only expressed a moderate level of satisfaction.
 
  Blended learning is a feasible pedagogical strategy for a clinical skill-based module. However, further investigation is required to explore the factors and strategies which could improve students' satisfaction.
 
  Blended learning has become one of the contemporary trends in education. Refining teaching strategies may meet the learning needs of today's generation and improve students' learning outcomes.

But we live in a multirisk world. This essay in honor of the 40th anniversary of the Society for Risk Analysis (SRA) and the journal Risk Analysis suggests that we can-and have already begun to-strengthen risk analysis and policy outcomes by moving from a focus on the single to the multiple-multiple stressors, multiple impacts, and multiple decisions. This evolution can improve our abilities to assess actual risks, to confront and weigh risk-risk trade-offs and innovate risk-superior moves, and to build learning into adaptive regulation that adjusts over time. Recognizing the multirisk reality can help us understand complex systems, foresee unintended consequences, design better policy solutions, and learn to improve.
