Trustworthiness In Sampling Selection: Remedies Against Introspective Chaos, Cécile Gabarre, Serge Gabarre

The Qualitative Report

The ethical dimension pertaining to protecting participants from psychological harm due to the in-depth nature of the inquiry and to the intimacy resulting from prolonged engagement is well-documented. This is laudable, but very few studies focused on guiding the researchers against chaotic emotions arising from introspectively questioning their beliefs and motivations and inspiring their judgments underlying their decisions. In our involvement with masters’ students’ thesis writing and research management training, supervision, and examination, we became aware of recurring cases of novice researchers silently disappearing from the program, eventually reappearing, continuously struggling with their thesis. Investigating this process, we identified the …

Exponential And Hypoexponential Distributions: Some Characterizations, George Yanev

School of Mathematical & Statistical Sciences Faculty Publications

The (general) hypoexponential distribution is the distribution of a sum of independent exponential random variables. We consider the particular case when the involved exponential variables have distinct rate parameters. We prove that the following converse result is true. If for some n ≥ 2, X1, X2, . . . , Xn are independent copies of a random variable X with unknown distribution F and a specific linear combination of Xj ’s has hypoexponential distribution, then F is exponential. Thus, we obtain new characterizations of the exponential distribution. As corollaries of the main results, we extend some previous characterizations established recently …
