Hence, these may go undiagnosed until they progress into greater severity. This exploratory study sought to (1) determine which scale items in the self-perceptual Evaluation of Ability to Sing Easily (EASE) are associated with instrumental voice measures, and (2) construct as proof-of-concept an instrumental index related to singers’ perceptions of their vocal function and health status. Eighteen classical singers were acoustically recorded in a controlled environment singing an /a/ vowel using soft phonation. Aerodynamic data were collected during a softly sung /papapapapapapa/ task with the KayPENTAX Phonatory Aerodynamic System. Using multi and univariate linear regression techniques, CPPS, vibrato jitter, vibrato shimmer, and an efficiency ratio (SPL/PSub) were included in a significant model (p < 0.001) explaining 62.4% of variance in participa...

In order to justify the names for latent variables, consider the way you choose an evaluation grade from a set of 9. The final choice reflects your feeling about the evaluated item, your past experience, your knowledge about it, and so on. On the other hand, there are some aspects concern with a basic uncertainty about the evaluated item, for example you are asked to deal with it for the first time and you don’t know what grade to choose, maybe the task is too difficult or the task is annoying you. These two main components are supposed to move your final choice and they are supposed to follow respectively a shifted Binomial distribution and a Uniform distribution [12, 18].

In order to test the null hypothesis of equality in distribution of the two underlying populations against an alternative of stochastic dominance, we extend the nonparametric combination-based permutation testing to such kind of data. The solution is valid both for continuous and for ordered categorical responses and the proposed method is investigated and validated by a suitable simulation study. A real case study in the field of toxicology is finally presented

Statistical variables represent the satisfaction levels of users or consumers. When evaluation takes into account more than one aspect the problem is quite complicated and some methodological and practical issues arise: standardization, multivariate structure of data, accuracy of partial indicators, distance with respect to target (highest satisfaction level), stratification in presence of confounding factors. The methodological solution here proposed overcomes these problems and gives an easy and useful instrument for performance analysis

The performance of a drive is intertwined with the reliability of the memories; hence, modeling their reliability is an important task to be performed as a support for storage system designers. In the literature, storage developers devise dedicated parametric statistical approaches to model the evolution of the memory’s error distribution through well-known statistical frameworks. Some of these well-founded reliability models have a deep connection with the 3D NAND flash technology. In fact, the more precise and accurate the model, the less the probability of incurring storage performance slowdowns. In this work, to avoid some limitations of the parametric methods, a non-parametric approach to test the model goodness-of-fit based on combined permutation tests is carried out. The results show that the electrical cha...

Elderly individuals are particularly vulnerable to severe infection, likely reflecting age-related changes in the immune system, which can also compromise vaccine efficacy. It has nonetheless remained unclear to what extent different vaccine platforms are impacted by immunosenescence. Here, we evaluated spike-specific immune responses elicited by vaccination with two doses of BNT162b2 or ChAdOx1-S and subsequently boosted with a single dose of BNT162b2 or mRNA-1273, comparing age-stratified participants with no evidence of prior infection with SARS-CoV-2. We found that ageing profoundly affected the durability of humoral responses and further limited spike-specific CD4+ T cell immunity as a function of progressive erosion of the naive lymphocyte pool in individuals vaccinated initially with BNT162b2, such that protective immunological memory was best maintained in the eld...

Oltre tre quarti degli studi che hanno partecipato all’indagine in oggetto sono organizzati in forma individuale. Questo dato mostra una analogia con il mondo delle imprese per le quali la forma organizzativa più diffusa è appunto quella individuale.
