Impact of early phase COVID-19 precautionary behaviors on seasonal influenza in Hong Kong: A time-series modeling approach.

Background: Before major non-pharmaceutical interventions were implemented, seasonal incidence of influenza in Hong Kong showed a rapid and unexpected reduction immediately following the early spread of COVID-19 in mainland China in January 2020. This decline was presumably associated with precautionary behavioral changes (e.g.

Career Preferences among Nursing Students: A Cross-Sessional Study.

Introduction: It is estimated that mores nurses are needed in the future, nursing students' career preferences are important to contribute the shortage of nursing manpower in Macao. Little is known regarding the preferences for nursing students' career preferences and related factors among nursing students.

Objective: To explore and investigate the career preferences and related factors among nursing students in Macao.

Prognostics for lithium-ion batteries using a two-phase gamma degradation process model.

To address the degradation of rechargeable batteries, this paper presents a two-phase gamma process model with a fixed change-point for modeling the voltage-discharge curves of battery cycle aging under a constant current. The model can be applied to estimate the state of charge (SOC) and the remaining useful discharge time (RUT) in a cycle with consideration of the effect of cycle aging, and can also be applied to estimate the state of life (SOL) and the remaining useful life (RUL) across cycles. The applications of the proposed model are demonstrated using the experimental cycle aging data of a lithium iron phosphate battery.

Relationship Between Gerontological Nursing Education and Attitude Toward Older People.

Background: Nursing students' attitudes toward older people affect the quality of care provided to the aging population. Although gerontological nursing has been delivered as a stand-alone course in Macao since 2008, Macao nursing students' attitudes toward older people have not been investigated.

Objective: The purposes of this study were 1) to explore nursing students' background information and attitudes toward older people and 2) to examine the presence of relationships between these factors and gerontological nursing education in Macao, a special administrative region of China.

A gamma process modeling approach for the comparison of dissolution profiles.

In this paper, we propose a stochastic gamma process model for assessing the similarity of two dissolution profiles. Based on the proposed stochastic model, we utilize the difference factor and similarity factor to test the similarity of two dissolution profiles based on bootstrap confidence intervals. The performances of the proposed methods are compared with a multivariate test procedure via Monte Carlo simulation studies.

Confidence intervals for a difference between proportions based on paired data.

We construct several explicit asymptotic two-sided confidence intervals (CIs) for the difference between two correlated proportions using the method of variance of estimates recovery (MOVER). The basic idea is to recover variance estimates required for the proportion difference from the confidence limits for single proportions. The CI estimators for a single proportion, which are incorporated with the MOVER, include the Agresti-Coull, the Wilson, and the Jeffreys CIs.

Exact and approximate unconditional confidence intervals for proportion difference in the presence of incomplete data.

Confidence interval (CI) construction with respect to proportion/rate difference for paired binary data has become a standard procedure in many clinical trials and medical studies. When the sample size is small and incomplete data are present, asymptotic CIs may be dubious and exact CIs are not yet available. In this article, we propose exact and approximate unconditional test-based methods for constructing CI for proportion/rate difference in the presence of incomplete paired binary data.
