ASSESSING THE DETERMINANTS OF PRIVATE WASTE COLLECTORS’ OPERATIONAL EFFICIENCY AND ITS EFFECT ON REVENUE: A CASE STUDY OF LAGOS WASTE MANAGEMENT SECTOR by Shehu Usman Adam

“…Using secondary data obtained from the Lagos Waste Management Authority (LAWMA) for 260 Private Sector Participants (PSPs), Structural Equation Modeling (SEM) procedure was adopted to analyze the theoretically justified model specified. Relying on SEM’s capacity to address endogeneity in cross-section data, the study avoided the possibility of repeating the confounding effects in previous studies, lending more reliability to estimated parameters and conclusions. …”

Perfectionism and rational-emotive behaviour as a motivational policy for human resource management by Yu. A. Filyasova

“…The article considers the concept of a perfectionist motivational policy, which promotes achieving a high level of intrinsic employee motivation that ensures accomplishment of the organisational duties maximum amount; meanwhile, additional compensation produces a motivation displacement effect. Theoretically, perfectionism, as the organisation corporate culture value, contributes to a significant resources saving for the personnel maintenance and development. …”

MIMO Radar Adaptive Waveform Design for Extended Target Recognition by Lulu Wang, Kai-Kit Wong, Hongqiang Wang, Yuliang Qin

“…The problems of multiple-input multiple-output (MIMO) radar adaptive waveform design in additive white Gaussian noise channels and multitarget recognition based on sequential likelihood ratio test are jointly addressed in this paper. Two information-theoretic waveform design strategies, namely, the optimal waveform for maximizing the mutual information (MI) between the extended target impulse response and the target echoes and the optimal waveform for maximizing the Kullback-Leibler (KL) divergence (or relative entropy), are applied in the multitarget recognition application. …”
