(R2070) Poisson-Exponentiated Weibull Distribution: Properties, Applications and Extension

In this article, we introduce a new member of the Poisson-X family namely, the Poisson-exponentiated Weibull distribution. The statistical as well as the distributional properties of the new distribution are studied, and the performance of the maximum likelihood method of estimation is verified by a simulation study. The flexibility of the distribution is illustrated by a real data set. We develop and study a reliability test plan for the acceptance or rejection of a lot of products submitted for inspection when their lifetimes follow the new distribution. A real data example is also given to illustrate the feasibility of the sampling plan developed. Later, we introduce a bivariate analogue of the Poisson-exponentiated Weibull distribution called the Farlie-Gumbel-Morgenstern bivariate Poisson-exponentiated Weibull distribution and consider the concomitants of order statistics that arise from this bivariate distribution. The distribution theory of the concomitants of order statistics is also developed

Leadership Reflections of the Pandemic: Perceptions from Aspiring Assistant Principals

The initial COVID-19 outbreak within the United States necessitated the implementation of rapid safety measures, prompting educational leadership to establish unprecedented protocols. In the spring of 2020, schools throughout Tennessee closed for in-person learning before re-opening with new protocols in the fall. The purpose of this study was to gain insight from Tennessee educators about the challenges they faced because of these educational protocols enacted by leadership. The study employed a phenomenological qualitative design. The study sample was comprised of ten educators enrolled in the Tennessee Department of Education\u27s Aspiring Assistant Principal Network. The data were collected using open-ended interview questions about participants’ experiences with educational protocols enacted by leadership in the wake of the COVID-19 pandemic. The data were analyzed utilizing the content analysis method to identify emergent themes. The results of the study indicate that improving communication from leadership, addressing educator workload with additional support, providing support systems to prevent burnout, enhancing technology integration through training and resources, and the review and revision of impractical policies, could support educators implementing protocols in a similar context

Female Breast Cancer Survivor’s Perspective of Support Systems in Trinidad and Tobago

Globally, breast cancer is the most common cancer affecting women. The Cancer Registry of Trinidad and Tobago indicated that 45.9% of the breast cancer cases belonged to the African ethnicity, 27.5% Asian Indian, and 14.7% mixed ethnicity. Research on female breast cancer survivors\u27 perspectives on support systems and care within the Caribbean region is limited. Therefore, this study aims to examine female breast cancer survivors\u27 perspective of support systems in Trinidad and Tobago. We conducted a cross-sectional study with 74 cancer survivors attending support groups. To be eligible, the participants had to be females 18 years or older, residents of Trinidad and Tobago diagnosed with breast cancer, and attending any support group session. The participants were asked to complete a self-administered questionnaire with questions regarding sociodemographic characteristics, benefits of support groups, and perception of quality of care. All (n=74) participants indicated they were part of a support group at the facility or elsewhere. Most participants were between 46-65 years old. The three primary factors identified influencing initial participation in the support groups were feeling emotionally detached from family, having no family support, cancer education opportunities, and spiritual well-being. Providing support groups reduces stress and anxiety by creating a safe environment to maintain a healthier quality of life coping behavior and improve survival rate. More research is needed to provide continuous education on essential coping skills after a breast cancer diagnosis
