Transmuted generalized exponential distribution: A generalization of the exponential distribution with applications to survival data

In this article, we investigate the potential usefulness of the three-parameter transmuted generalized exponential distribution for analyzing lifetime data. We compare it with various generalizations of the two-parameter exponential distribution using maximum likelihood estimation. Some mathematical properties of the new extended model including expressions for the quantile and moments are investigated. We propose a location-scale regression model, based on the log-transmuted generalized exponential distribution. Two applications with real data are given to illustrate the proposed family of lifetime distributions.     

Transmuted Weibull distribution: Properties and estimation

In this article, we investigate the potential usefulness of the three-parameter transmuted Weibull distribution for modeling survival data. The main advantage of this distribution is that it has increasing, decreasing or constant instantaneous failure rate depending on the shape parameter and the new transmuting parameter. We obtain several mathematical properties of the transmuted Weibull distribution such as the expressions for the quantile function, moments, geometric mean, harmonic mean, Shannon, Rényi and q-entropies, mean deviations, Bonferroni and Lorenz curves, and the moments of order statistics. We propose a location-scale regression model based on the log-transmuted Weibull distribution for modeling lifetime data. Applications to two real datasets are given to illustrate the flexibility and potentiality of the transmuted Weibull family of lifetime distributions.     

College Health as a Partner in the Care of Pediatric Cancer Survivors

Abstract

Objective: This study reviews an initiative to educate providers on pediatric cancer survivor care and to establish a cancer survivor registry in a college health center. Participants: Participants were University of Georgia (UGA) college health providers. Methods: Providers attended lectures on survivor care and were encouraged to register on Cancer SurvivorLink. Changes in provider familiarity and practice were measured using baseline and follow-up surveys. A survivor registry was created using health entrance forms and medical records abstraction. Results: Twenty-four providers registered on SurvivorLink, and 16 completed both surveys. Familiarity with survivor care (p = .003) and a survivor health care plan (p = .016) increased. Likelihood to deliver survivor care increased (p = .01). UGA follows 95 survivors; 71 diagnosed at < 21 years. Among survivors diagnosed at < 21 years, 91% reported their diagnosis on entrance forms. Conclusions: Through education and optimization of health informatics, college health centers can identify and provide survivor care to this medically vulnerable population.     

The Educational Soundscape: Participation and Perception in Japanese High School English Lessons

In this article I discuss the emergence of practices of hearing in the midst of English language learning activities. I focus on listening activities during oral English lessons at two public high schools in Tokyo, Japan. One setting is a liberal arts high school. The other is a technical high school where students are trained in specializations such as industrial chemistry and electrical engineering. The different organization of listening activities in each of the schools has consequences for the different shape, texture, and categorization of what is heard. I show how hearing, therefore, is an act not solely located the moment sound meets the ear of an individual. Rather, it is socially rationed, controlled, and imagined through the joint actions of participants before, during, and after such physiological hearing takes place. This constitutes hearing as a social act, cognitively distributed among participants and over space and time in the classroom.
