Development of a Short Scale to Measure Sustainable Product Involvement

This study develops a short, general scale to measure sustainable product involvement. This is done in a Costa Rican context, via a relatively large sample, demographically similar to the national population. The study also evaluates the viability of the C-OAR-SE scaling technique for this purpose. A five-item instrument is developed, its reliability and validity psychometrically confirmed. The scale addresses the levels and types of involvement that consumers might have. It suits not only academic researchers, but also practitioners in different areas. We conclude that C-OAR-SE is a viable technique. It complements traditional psychometric methods well so as to be considered by researchers in the different fields of business.

Oscillation Criteria of Second-Order Dynamic Equations on Time Scales

In this paper, we consider the oscillation behavior of the following second-order nonlinear dynamic equation. λ(s)Ψ1φΔ(s)y(φ(s))ΔΔ+η(s)Φ(y(τ(s)))=0,s∈[s0,∞)T. By employing generalized Riccati transformation and inequality scaling technique, we establish some oscillation criteria.

Error-Tolerant Reconfigurable VDD 10T SRAM Architecture for IoT Applications

This paper proposes an error-tolerant reconfigurable VDD (R-VDD) scaled SRAM architecture, which significantly reduces the read and hold power using the supply voltage scaling technique. The data-dependent low-power 10T (D2LP10T) SRAM cell is used for the R-VDD scaled architecture with the improved stability and lower power consumption. The R-VDD scaled SRAM architecture is developed to avoid unessential read and hold power using VDD scaling. In this work, the cells are implemented and analyzed considering a technologically relevant 65 nm CMOS node. We analyze the failure probability during read, write, and hold mode, which shows that the proposed D2LP10T cell exhibits the lowest failure rate compared to other existing cells. Furthermore, the D2LP10T cell design offers 1.66×, 4.0×, and 1.15× higher write, read, and hold stability, respectively, as compared to the 6T cell. Moreover, leakage power, write power-delay-product (PDP), and read PDP has been reduced by 89.96%, 80.52%, and 59.80%, respectively, compared to the 6T SRAM cell at 0.4 V supply voltage. The functional improvement becomes even more apparent when the quality factor (QF) is evaluated, which is 458× higher for the proposed design than the 6T SRAM cell at 0.4 V supply voltage. A significant improvement of power dissipation, i.e., 46.07% and 74.55%, can also be observed for the R-VDD scaled architecture compared to the conventional array for the respective read and hold operation at 0.4 V supply voltage.

Increasing Brand Trust through Marketing Communication and Its Impact on School principal's Loyalty

The purpose of this study is to determine the effect of communication marketing on school principal loyalty through brand trust. The approach in this research was quantitative. The data were obtained through a questionnaire with the Likert scaling technique. The population and sample in this study was 45 principals of high school, vocational and Aliyah private schools in Binjai and Langkat district. The sampling technique was accidental sampling was 45 respondents. The results showed that 1) marketing communication has a significant effect on brand trust. 2) Marketing communication has no effect on principal loyalty. 3) Student brand trust has a significant effect on the principal's loyalty. 4) Marketing communication has a significant effect on principal loyalty through brand trust.
