Abstract : A study is reported of the variations in organizational commitment and job satisfaction, as related to subsequent turnover in a sample of recently-employed psychiatric technician trainees. A longitudinal study was made across a 10 1/2 month period, with attitude measures collected at four points in time. For this sample, job satisfaction measures appeared better able to differentiate future stayers from leavers in the earliest phase of the study. With the passage of time, organizational commitment measures proved to be a better predictor of turnover, and job satisfaction failed to predict turnover. The findings are discussed in the light of other related studies, and possible explanations are examined. (Modified author abstract)

Exogenous melatonin as a treatment for secondary sleep disorders: A systematic review and meta-analysis.

This article introduces a single-switch, high step-up, dc–dc converter based on coupled-inductor with three winding and voltage multiplier cell to obtain a very high-voltage conversion ratio. A passive clamp circuit is applied in the converter to recycle the energy of leakage inductance and reduce voltage stress of the main power switch. This leads to utilize a power switch with low on-state resistance and low voltage rating that decreases the conduction losses. Several advantages include low operating duty cycle, high voltage conversion ratio, low turn ratio of the coupled inductor, leakage inductance reverse recovery, reduced voltage stress of semiconductors, alleviation of diodes reverse recovery issue and high efficiency, which make the presented topology appropriate for sustainable energy applications such as photovoltaic systems. The operation principle and steady-state analysis of the suggested topology in continuous conduction mode are expressed in detail. Also, design procedure and theoretical efficiency analysis of the proposed topology are presented. Moreover, a comparison study is performed to demonstrate the superiority of the presented converter over several similar recently proposed dc–dc converters. Finally, the proposed dc–dc converter feasibility and performance are justified through a fabricated 216-W laboratory prototype at 50 kHz switching frequency.

A High Voltage Gain DC–DC Converter Based on Three Winding Coupled Inductor and Voltage Multiplier Cell

This paper presents a new interleaved coupled-inductor nonisolated bidirectional dc–dc converter that provides high voltage gain ratio (VGR), low ripple current at the low-voltage side (LVS), and soft switching. The high VGR is obtained by connecting in series the outputs of an interleaved bidirectional buck–boost converter and a dual-active half-bridge converter, using the turns ratio of a coupled inductor. Since the voltage of the high-voltage side is shared between the converters outputs, the voltage stress across the active switches decrease. The active switches turn ON under zero-voltage switching condition in both directions. Moreover, the low current ripple at the LVS is achieved due to the applied interleaved technique. By employing the phase-shift angle modulation, the output voltage is regulated. The proposed converter is analyzed in details and a 900-W experimental prototype with 48-V input voltage and 400-V output voltage under 100-kHz switching frequency is implemented to verify the theoretical results.

The aim of this study is to explore the impact of job security on employees’ commitment and job satisfaction in Qom municipalities. This research is conducted as a descriptive and field study. Its population consists of employees (N = 158). To collect data, two Wysocki and Kromm job satisfaction and Mowday, Steers and Porter organizational commitment questionnaires were utilized. To analyze data, Spearman’s correlation coefficient, t-test and step-by-step multivariable regression analysis test were used. Research findings show that there is a significant difference between hired/contractual employees and organizational commitment. In the meantime, there is a difference between employees’ job satisfaction but it is not significant. There is also a positive and direct significant correlation between job satisfaction and organizational commitment. Multivariable regression test shows that wage satisfaction and colleagues’ satisfaction have the highest impact on organizational commitment.

The interleaving technique is a well-known technique applied in high power applications to share the output power between two modules while decreasing the input current and output current ripple. Moreover, zero current switching technique can be used in order to reduce the switching losses and increase the power density. Zero-current-switching (ZCS) condition as the soft-switching technique is usually applied for IGBT switches in order to eliminate tailing current losses. In this study, a new ZCS pulse-width-modulation (ZCS-PWM) interleaved boost converter is proposed which applies only one auxiliary switch. In the proposed converter ZCS condition is provided for main switches while the auxiliary switch is also soft switched. The principle of operation, performance analysis, and design method of the proposed converter are presented in details. Finally, the theoretical results are verified by experimental results.

Background Disturbed sleep is common in shift work. It is hypothesized that administration of exogenous melatonin could reduce the sleep latency and improve the sleep quality. Objective To evaluate the efficacy of 3 mg melatonin taken 30 min before night time sleep on shift workers with difficulty falling asleep. Methods Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were applied to find out shift workers with difficulty falling asleep. A randomized, double-blind, placebo-controlled crossover study with periods of 3 night and washouts of 2 weeks comparing melatonin with placebo was performed. Night time sleep parameters obtained from somnowatch including total sleep time (TST), sleep onset latency (SOL), sleep efficiency (SE) and wakening after sleep onset (WASO) were analyzed. Results Among 295 workers, 103 had difficulty falling asleep. Finally, from 50 randomly selected workers with difficulty falling asleep, 39 workers completed the study. Melatonin treatment significantly increased SE and decreased SOL in comparison with baseline and taking placebo. SE was increased from 82.1% at baseline to 85.5% after melatonin therapy. Also SOL was decreased from 0.27 h at baseline to 0.20 h after melatonin therapy. Effects of Melatonin administration on TST and WASO were not significant. Conclusions This study showed that melatonin therapy in shift workers with difficulty falling asleep significantly improved the sleep onset latency and sleep efficiency.

In this study, a modified efficient step-up boost converter is proposed. The proposed structure employs coupled-inductor and super-lift techniques to achieve high voltage gain. The super-lift stage absorbs the available energy in the leakage inductance of the coupled inductor, clamps the off-state voltage of the main switch, and reaches a moderate voltage gain. Moreover, the coupled-inductor technique offers high voltage gain, low off-state voltage for the main switch, and alleviates the reverse-recovery problem of the output diode. Hence, using these two techniques, the proposed converter achieves high step-up voltage gain and eliminates the drawbacks of the conventional boost converter. The proposed converter is analysed in details and a hardware prototype with the input voltage of 15 V, output voltage of 200 V and the nominal power of 100 W is utilised for the experimental investigation.
