Strategies for Developing Modern Administrators’ Change Leadership at Mahamakut Buddhist University

This mixed methods research has main objectives consisting of investigating the components and creating strategies for the development of change leadership in the modern age among the administrators of Mahamakut Buddhist University. The sample consisted of administrators, teachers, and officers working in Mahamakut Buddhist University. Based on the implications of Krejcie and Morgan’s (1970) table for sample size allocation, a total of 262 samples were recruited. The quality of the research instruments can be verified by the content validity and reliability with an IOC of between 0.80 - 1.00 and a reliability of 0.98. The current existing condition of the change leadership for both the overall and the itemized analysis was found to be at a “Moderate level”. The strategies for the development of change leadership in the modern age among the administrators of Mahamakut Buddhist University had consisted of the following: 1) six measures for participation at work, 2) seven measures for collective vision, 3) six measures for the promotion of Wisdom exercises, 4) five measures for incentive and inspiration creation, and 5) six measures for promotion of teamwork.

Estimation of optimum sample size allocation: An illustration with body mass index for evaluating the effect of a dietetic supplement

In many medical researches, it is needed to determine the optimal sample size allocation in a heterogeneous population. This paper proposes the algorithm for optimal sample size allocation. We consider the optimal allocation problem as an optimization problem and the solution is obtained by using Bisection, Secant, Regula–Falsi and other numerical methods. The performance of the algorithm for different numerical methods are analyzed and evaluated in terms of computing time, number of iterations and gain in accuracy using stratification. The efficacy of algorithm is evaluated for the response in terms of body mass index (BMI) to the dietetic supplement with diabetes mellitus, HIV/AIDS and cancer post-operatory recovery patients.

Sample Size Calculations for Testing Equivalence of Two Exponential Distributions With Right Censoring

The present study considered two independent exponential distributions with the hypothesis for testing equivalence of lifetime means or failure rates, and aimed to determine the required uncensored sample size based on power, sampling cost, and censoring proportion simultaneously in the case of right censoring. Approximate sample size formulas with an iterative procedure were proposed and an uncensored sample size allocation ratio was derived to minimize the total cost for a designated power or maximize statistical power for a limit cost. R codes are provided for easy application. The proposed methods are validated in terms of Type I errors and statistical power in a simulation study, and are recommended for the future use.
