Resumen A software reliability analysis for the first stage of software projects is presented. At this very first stage of testing we expect an increasing failure rate, where the usual software reliability growth models based on non homogeneous Poisson processes like the Goel-Okumoto or Musa-Okumoto can not be applied. However, our analysis involves some models that combine reliability growth with increasing failure rates like the logistic and delayed S-shaped models. Our analysis also includes a new model based on contagion as in the increasing failure rate as in the reliability growth stages. We point out that increasing failure rate stages are important to be modeled since corrective actions can be taken soon and also that this characteristics highlights under modern development methodologies which development is performed simultaneously as testing, like in Agile and TDD (Test driven development). Results of the application of those models to real datasets is shown.

I find it to be incredibly fascinating as a researcher to follow the development of a profession and the specializations within it. The history of addiction counseling, a subfield of the counseling profession, has developed in a manner like that of many other helping professions, including social work, psychiatry, nursing, and medicine. In the past, practitioners had less training and supervision when it came to understanding addiction as a condition that would call for professional assistance. It will substantially advance the body of research and aid counselors in their understanding of the values and requirements of various people. In order to comprehend the etiology of addiction, this article also analyses many causation models, such as moral, psychological, family, disease, biological, sociocultural, and multi-cause models. Addiction counselors are not merely specialists who work with alcoholics or addicts in recovery solely on the basis of their former substance use. Addiction...
