Being satisfied and serving communities as outcomes of servant leadership in the academic context: policies based on a multi-level structural equation model

Ghasemy, Majid,Akbarzadeh Mahdi,Gaskin, James Eric 서울대학교 교육연구소 2022 Asia Pacific Education Review Vol.23 No.1

There is a great emphasis on the importance of serving communities and the need to study servant leadership in recent higher education literature. Yet, academics’ community citizenship behavior has not been examined through applied research. To address these issues, our study aims at investigating the effects of two dimensions of servant leadership (behaving ethically and helping subordinates grow and succeed) on job satisfaction and community citizenship behavior. The context of our multi-level study is the Malaysian higher education. To estimate our theoretical model, we employed the EQS 6.4 statistical package and analyzed the data collected from 1876 lecturers from 120 departments using a multi-level structural equation modeling (MSEM) methodology. Our results revealed two completely different model structures at both lecturer and department levels. More specifically, while both the predictors were useful for explaining the outcome variables at the lecturer level, we observed that only behaving ethically was a significant predictor of community citizenship behavior at the department level. We discuss the findings in detail and elaborate on the implications of the findings with respect to policy and practice, theory, and methodology. We also address limitations and make recommendations for future research.

Majid Ghasemy,Sufean Hussin,Megat Ahmad Kamaluddin Megat Daud 서울대학교 교육연구소 2016 Asia Pacific Education Review Vol.17 No.2

Previous studies have shown that leadership capabilities and managerial competencies are related to leadership performance effectiveness, i.e., higher capabilities and competencies are associated with higher performance effectiveness, and vice versa. Among the studies focusing on these qualities in academic settings, two recent studies in Australia and New Zealand in 2008 and 2012 may be stated which were guided by a conceptual framework known as the Academic Leadership Capability Framework. This framework became the basis for the construction of a survey instrument in order to assess five vital components of university leadership. The framework and the survey instrument were employed for a similar study in Malaysian public and private universities. In performing descriptive analysis, the results of the three studies were compared. This analysis revealed interesting similarities and differences among academic leaders within the three countries which can be used as a base for further policy making, and characterizing effective leadership in higher education. In addition, inferential statistics techniques were employed to detect the impact of the University Type and Previous Experience outside higher education on capabilities, competencies, and performance of the Malaysian academic leaders.

This study was undertaken to determine the extent to which leadership capabilities and managerial competencies explain leadership performance in Malaysian Higher Education context. Data were collected from academic leaders in 25 public and private universities and colleges using a few previously developed scales in Malaysian context. Next, the collected data through 368 surveys were screened thoroughly prior to the main analysis. A variance-based structural equation modeling approach was adopted and SmartPLS 3 was used to analyze the data, followed by running finite mixture segmentation and importance-performance map analysis. The results did disclose unobserved heterogeneity within the data. Through the study, two models namely low-current-tenure leaders and high-current-tenure leaders models were developed. Moreover, role-specific competency and change-oriented capability were identified as the major areas of improvement to be addressed by managerial activities based on low-current-tenure leaders and high-current-tenure leaders models, respectively.

Nahid Ghasemi,Maryam Ghasemi,Saleh Moazeni,Parisa Ghasemi,Njud S. Alharbi,Vinod Kumar Gupta,Shilpi Agarwal,Irina V. Burakova,Alexey G. Tkachev 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.62 No.-

In this study, a novel adsorbent, dioctylphetalate triethylenetetraamine magnetic nanoparticles (DOP-TETA-MNP) via a solvent-free procedure were synthesized for the removal of Zn (II) ions from aqueous solution. The morphological and anatomical characterization was investigated by various analytical techniques such as FTIR and SEM. Experimental data from evaluation of various influential parameters such as initial pH (2–7), initial ion concentration (5–20 mg/L), adsorbent dose (0.005–0.040 g), contact time (5–120 min) and temperature (308–333 K) of the solution were carried out using a batch adsorption method. DOP-TETA-MNP can be simply separated from aqueous solution with magnetic separations at low magnetic field. The kinetic data of Zn (II) ions were found to follow the pseudo-second-order kinetic model and the equilibrium data of ions sorption were well described by Langmuir isotherm model. The maximum monolayer sorption capacity of Zn (II) was estimated to be 24.21 mg/g at temperature of 333 K. Thermodynamic analyses show that the adsorption process is exothermic and spontaneous.

This research aims to fabricate and develop a composite brake disc made of carbon/silicon carbide. For this purpose, the first silicon carbide nanoparticles were ultrasonicated with alumina sintering aid and carbon fi ber (between 10 and 20%) with different lengths of 3 mm, 10 mm, and 15 mm. Next, the fi nal Cf/SiC composite bulk was made-up via the spark plasma sintering (SPS) method. After that, the effect of different lengths of carbon fiber was explored on the porosity, coefficient of friction, fracture toughness, thermal conductivity, and microhardness of samples. The results showed that the density of sintered samples with a carbon fiber length of 10 mm was higher than that of samples with fiber lengths of 3 and 15 mm. Also, the hardness (25.79 GPa) and fracture toughness (5.72 MPa.m 1/2) of this sample were higher than those of the samples sintered with carbon fiber lengths of 3 and 15 mm. Further, this sample with the maximum density showed a coefficient of friction (COF) of 0.43. Since for aeroplane brake discs, the COF should be between 0.3 and 0.4, and the porosity of sam- ples should range within 3–5%, the samples sintered with the carbon fiber length of 10 mm had the nearby features to the preferred air brake disc indices.

Surprising Incentive: An Instrument for Promoting Safety Performance of Construction Employees

Ghasemi, Fakhradin,Mohammadfam, Iraj,Soltanian, Ali Reza,Mahmoudi, Shahram,Zarei, Esmaeil Occupational Safety and Health Research Institute 2015 Safety and health at work Vol.6 No.3

Background: In comparison with other industries, the construction industry still has a higher rate of fatal injuries, and thus, there is a need to apply new and innovative approaches for preventing accidents and promoting safe conditions at construction sites. Methods: In this study, the effectiveness of a new incentive system-the surprising incentive system-was assessed. One year after the implementation of this new incentive system, behavioral changes of employees with respect to seven types of activities were observed. Results: The results of this study showed that there is a significant relationship between the new incentive system and the safety performance of frontline employees. The new incentive system had a greater positive impact in the first 6 months since its implementation. In the long term, however, safety performance experienced a gradual reduction. Based on previous studies, all activities selected in this study are important indicators of the safety conditions at workplaces. However, there is a need for a comprehensive and simple-to-apply tool for assessing frontline employees' safety performance. Shortening the intervals between incentives is more effective in promoting safety performance. Conclusion: The results of this study proved that the surprising incentive would improve the employees' safety performance just in the short term because the surprising value of the incentives dwindle over time. For this reason and to maintain the surprising value of the incentive system, the amount and types of incentives need to be evaluated and modified annually or biannually.

Ghasemi, Mohammad R.,Ghasri, Mehdi,Salarnia, Abdolhamid Techno-Press 2022 Advances in computational design Vol.7 No.4

Due to their natural and social revelation, also their ease and flexibility, human collective behavior and teamwork sports are inspired to introduce optimization algorithms to solve various engineering and scientific problems. Nowadays, meta-heuristic algorithms are becoming some striking methods for solving complex real-world problems. In that respect in the present study, the authors propose a novel meta-innovative algorithm based on soccer teamwork sport, suitable for optimization problems. The method may be referred to as the Soccer League Optimization-based Championship Algorithm, inspired by the Soccer league. This method consists of two main steps, including: 1. Qualifying competitions and 2. Main competitions. To evaluate the robustness of the proposed method, six different benchmark mathematical functions, and two engineering design problem was performed for optimization to assess its efficiency in achieving optimal solutions to various problems. The results show that the proposed algorithm may well explore better performance than some well-known algorithms in various aspects such as consistency through runs and a fast and steep convergence in all problems towards the global optimal fitness value.

Applications, Shortcomings, and New Advances of Job Safety Analysis (JSA): Findings from a Systematic Review

Ghasemi Fakhradin,Doostiirani Amin,Aghaei Hamed 한국산업안전보건공단 산업안전보건연구원 2023 Safety and health at work Vol.14 No.2

Background: Job safety analysis (JSA) is a popular technique for hazard identification and risk assessment in workplaces that has been applied across a wide range of industries. This systematic review was conducted to answer four main questions regarding JSA: (1) which sectors and areas have used JSA? (2) What has been the aim of employing JSA? (3) What are the shortcomings of JSA? (4) What are the new advances in the field of JSA? Methods: Three main international databases were searched: SCOPUS, Web of Science, and PubMed. After screening and eligibility assessment, 49 articles were included. Results: Construction industries have used JSA the most, followed by process industries and healthcare settings. Hazard identification is the main aim of JSA, but it has been used for other purposes as well. Being time-consuming, the lack of an initial list of hazards, the lack of a universal risk assessment method, ignoring hazards from the surrounding activities, ambiguities regarding the team implementing JSA, and ignorance of the hierarchy of controls were the main shortcomings of JSA based on previous studies. Conclusion: In recent years, there have been interesting advances in JSA making attempts to solve shortcomings of the technique. A seven-step JSA was recommended to cover most shortcomings reported by studies.

Sulfur-Emission-Free Process of Molybdenum Carbide Synthesis by Lime-Enhanced Molybdenum Disulfide Reduction with Methane

Ghasemi, Samad,Abbasi, Mohammad Hasan,Saidi, Ali,Kim, Jae Yul,Lee, Jae Sung American Chemical Society 2011 INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH - Vol.50 No.23

<P>To investigate a sulfur-emission-free process of molybdenum carbide synthesis from molybdenite, the reaction pathways of MoS<SUB>2</SUB> reduction with methane in the presence of lime (CaO) have been studied. A mixture of MoS<SUB>2</SUB> + 2CaO was reduced isothermally with CH<SUB>4</SUB> in a microreactor, and the composition of effluent gases and the reduced fraction were determined as a function of reaction time. Analysis of the solid phase at different reaction times at 800 °C showed the formation of CaMoO<SUB>4</SUB> as an intermediate phase. Hence, the reaction pathways proposed for reduction of MoS<SUB>2</SUB> + CaO with CH<SUB>4</SUB> involves the direct reduction of MoS<SUB>2</SUB> with CH<SUB>4</SUB> to form Mo<SUB>2</SUB>C and sulfur-containing gases. The sulfur-containing gases are captured by CaO to form CaS, CO(g), CO<SUB>2</SUB>(g), and H<SUB>2</SUB>O(g). The unreacted MoS<SUB>2</SUB> is oxidized by CO<SUB>2</SUB>(g) and H<SUB>2</SUB>O(g) to form MoO<SUB>3</SUB>(g), which reacted with CaO to form CaMoO<SUB>4</SUB> on CaO particles. Finally, CaMoO<SUB>4</SUB> and remaining MoS<SUB>2</SUB> are further reduced with CH<SUB>4</SUB>. Characterization of solid samples was carried out by XRD, CHN, and FE-SEM equipped with EDS, providing results consistent with the proposed reaction pathways. Carbon content of solid sample increased with reduction time, and in fully reduced sample at 800 °C it was well above the stoichiometric amount indicating considerable excess carbon deposition due to CH<SUB>4</SUB> cracking.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/iecred/2011/iecred.2011.50.issue-23/ie201860h/production/images/medium/ie-2011-01860h_0010.gif'></P>
