Low manufacturing and maintenance cost also attract people to go for evacuated tube solar water heaters. This paper reports experimental results of two types of evacuated tube solar water heaters. To evaluate the performance of evacuated tube solar water heater, single-phase forced system and two-phase closed forced systems were considered. In two-phase closed system sunflower oil was used as working fluid to heat water. Throughout the study two-phase closed system shows better performance compared to single-phase open collector system and their efficiency almost 10 to 12% higher. But, because of high initial cost of two-phase system, the pay back periods of both collector systems is almost same. In two phased closed system higher temperature of water could be achieved, which i...

Anger and negative affectivity are two personality traits that have been linked to workplace deviant behavior conduct. Objective: This study aimed to empirically analyze the deviant workplace behavior and its antecedents among Malaysian nurses in public hospitals. Methods: A cross-sectional design was employed in this study. The survey questionnaires were distributed proportionately to staff nurses in six government hospitals in 2020, with a total of 387 nurses selected using a simple random sampling. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used for data analysis. Results: Trait anger triggered deviant workplace behavior in Malaysian nurses, thus supporting the argument that the personality trait could increase deviant behavior (β = 0.245, p = 0.000). At the same time, there was no evidence that negative affectivity could influence deviant behavior in the work...

AMOS is popular since it is more flexible than other statistical packages. Historically, this software was developed by Jim Arbuckle in 1995 and is widely employed by academicians since then. This software has become even more popular after distributor IBM distributes itworldwide with SPSS where Amos is one of its applications. Consequently, higher education institutions subscribing SPSS have AMOS automatically; and they areadopting the CBSEM technique. Although an enormous number of journal articles are being published using CBSEM, a number of instructional materials for researchersto follow are still limited especially in addressing the Higher Order Constructs (HOC). This paper intends to address this knowledge gap and help researchers to understand properly how to address HOC in their work. The paper outlines properguides for application an...

Some of the researchers classify SEM as the covariance-based SEM (CB-SEM). However, this method have been argued since its application should achieved the criterion before conducting the measurement and structural model. Thus, partial least square SEM (PLS-SEM) has been established to solve this problems. This paper aims to examine which one of the structural equation modeling is appropriate to use for confirmatory factor analysis by using SMARTPLS and AMOS. In this instance, the data of volunteerism program is chosen as a research subject to prove this issue. The author revealed that PLS-SEM path modeling using SMARTPLS is appropriate to carry on the confirmatory factor analysis which is more reliable and valid.
