From a survival analysis perspective, bank failure data are often characterized by small default rates and heavy censoring. This empirical evidence can be explained by the existence of a subpopulation of banks likely immune from bankruptcy. In this regard, we use a mixture cure model to separate the factors with an influence on the susceptibility to default from the ones affecting the survival time of susceptible banks. In this paper, we extend a semi-parametric proportional hazards cure model to time-varying covariates and we propose a variable selection technique based on its penalized likelihood. By means of a simulation study, we show how this technique performs reasonably well. Finally, we illustrate an application to commercial bank failures in the United States over the period 2006–2016.

In this review, a critical reading of the literary and scientific production focused on the themes of the body, movement and language learning was carried out, with particular consideration given to alternative teaching methods that use movement to favour the cognitive process. After searching the databases of Pub Med, PsycInfo, Sport Discus, Psyc Articles and Eric electronic, the choice was narrowed down to 8 international scientific studies with publication dates ranging between the years 1999 and 2017 concerning pre-school subjects between 2 and 5 years of age, excluding those regarding other target users and/or particular characteristics such as pathologies, obesity, and nutrition. All of these studies analysed the benefits of motor activity on language, communication, learning and academic performance. Of the 7 filtered studies, 4 examine the specific relationship between motor activity and language, while the other 3 between language and general academic performance. Through the analysis of the filtered reports and some of the bibliographical references used, we conclude that motor activity positively influences language, attention and concentration of the pupils in this age range, with effects on academic performance. Furthermore, it also improves motor skills as a result of decreased sedentary behaviour. [ABSTRACT FROM AUTHOR]
