Concerns with AED conversion: comparison of patient and physician perspectives.
When discussing AED conversion in the clinic, both the patient and physician perspectives on the goals and risks of this change are important to consider. To identify patient-reported and clinician-perceived concerns, a panel of epilepsy specialists was questioned about the topics discussed with patients and the clinician's perspective of patient concerns. Findings of a literature review of articles that report patient-expressed concerns regarding their epilepsy and treatment were also reviewed. Results showed that the specialist panel appropriately identified patient-reported concerns of driving ability, medication cost, seizure control, and medication side effects. Additionally, patient-reported concerns of independence, employment issues, social stigma, medication dependence, and undesirable cognitive effects are important to address when considering and initiating AED conversion
Phase transition of the susceptible-infected-susceptible dynamics on time-varying configuration model networks
We present a degree-based theoretical framework to study the
susceptible-infected-susceptible (SIS) dynamics on time-varying (rewired)
configuration model networks. Using this framework, we provide a detailed
analysis of the stationary state that covers, for a given structure, every
dynamic regimes easily tuned by the rewiring rate. This analysis is suitable
for the characterization of the phase transition and leads to three main
contributions. (i) We obtain a self-consistent expression for the
absorbing-state threshold, able to capture both collective and hub activation.
(ii) We recover the predictions of a number of existing approaches as limiting
cases of our analysis, providing thereby a unifying point of view for the SIS
dynamics on random networks. (iii) We reinterpret the concept of hub-dominated
phase transition. Within our framework, it appears as a heterogeneous critical
phenomenon : observables for different degree classes have a different scaling
with the infection rate. This leads to the successive activation of the degree
classes beyond the epidemic threshold.Comment: 14 pages, 11 figure
A State-Level Analysis of the Great Moderation
A number of studies have documented a reduction in aggregate macroeconomic volatility beginning in the early 1980s. Using an empirical model of business cycles, we extend this line of research to state-level employment data, find significant heterogeneity in the timing and magnitude of the state-level volatility reductions. In fact, some states experience no statistically-significant reduction in volatility. We then exploit this cross-sectional heterogeneity to evaluate three hypotheses about the origin of the aggregate volatility reduction. We show that states with relatively higher manufacturing concentration experience later breaks, a result that tends to contradict improved inventory management and a decline in the volatility of productivity shocks as possible explanations. Our results, then, are more consistent with monetary policy as the origin of the aggregate volatility reductiondisaggregation, volatility reduction, Markov-switching
