Although mediating variables are of importance in the HPWS-Performance nexus, identification of the fitting intervening variable(s) that mediates between the nexuses is a crucial issue, and the number of the mediating variable(s) which would unravel the so called “black box” remains un-resolved and the most burning theoretical and empirical challenge in the Strategic HRM research field. Likewise, moderating variables do have impacts on the HPWS-Performance nexus since the context within which firm operates and the strategic orientations of firms have bearing on the application of HR practices and its effect on the firm’s performance. Given this, this work pro-posed a model which is theorized based on the far-reaching survey of the extant literature. The model theorizes the mediating role of employee creativity and potential moderating role of man-agement philosophy in the HPWS-performance nexus via extensive theoretical and logical argu-ment and exposition. Also, as established by the extant research, HPWS measurement in the context of SME should be employee-oriented, therefore, this work measured HPWS with eight employee-oriented HR architectures, and performance is measured with financial and non-financial performance, for being a widespread adopted measurement in many fields of study.
Cell load variation is considered a significant shortcoming in scheduling of cellular manufacturing systems. In this article, a new method is proposed for scheduling dynamic cellular manufacturing systems in the presence of bottleneck and parallel machines. The aim of this method is to control cell load variation during the process of determining the best trading off values between in-house manufacturing and outsourcing. A genetic algorithm (GA) is developed because of the high potential of trapping in the local optima, and results are compared with the results of LINGO® 12.0 software. The Taguchi method (an L_9 orthogonal optimization) is used to estimate parameters of GA in order to solve experiments derived from literature. An in-depth analysis is conducted on the results in consideration of various factors, and control charts are used on machine-load variation. Our findings indicate that the dynamic condition of product demands affects the routing of product parts and may induce machine-load variations that yield to cell-load diversity. An increase in product uncertainty level causes the loading level of each cell to vary, which in turn results in the development of “complex dummy sub-cells”. The effect of the complex sub-cells is measured using another mathematical index. The results showed that the proposed GA can provide solutions with limited cell-load variations.
Job selection and scheduling are among the most important decisions for production planning in today’s manufacturing systems. However, the studies that take into account both problems together are scarce. Given that such problems are strongly NP-hard, this paper presents an approach based on two heuristic algorithms for simultaneous job selection and scheduling. The objective is to select a subset of jobs and schedule them in such a way that the total net profit is maximized. The cost components considered include jobs & apos; processing costs and weighted earliness/tardiness penalties. Two heuristic algorithms; namely scatter search (SS) and simulated annealing (SA), were employed to solve the problem for single machine environments. The algorithms were applied to several examples of different sizes with sequence-dependent setup times. Computational results were compared in terms of quality of solutions and convergence speed. Both algorithms were found to be efficient in solving the problem. While SS could provide solutions with slightly higher quality for large size problems, SA could achieve solutions in a more reasonable computational time.
The role of leaders toward the development of entrepreneurship has been fully acknowledged. However, Leaders’ characteristics such as strategic improvisation and entrepreneurial self-efficacy were mainly examined in the private sector. Hence, it is imperative to extend empirical studies to public sector organizations. The present study, therefore, proposed and validated a model linking leaders’ strategic improvisation and entrepreneurial self-efficacy to corporate entrepreneurship in Nigerian higher education institutions (HEIs). Using a structured questionnaire, 220 responses were generated from large HEIs in Kano State, Nigeria. The data of the study was analysed using SmartPLS 3.0 to ascertain both measurement and structural model validity of the model. The results showed that both leaders’ strategic improvisation and entrepreneurial self-efficacy were significantly related to corporate entrepreneurship in HEIs. Implication and limitation of the study; and suggestions for future study are also provided.
Improving employee and organizational performance has been the main concern of many organizations for decades and several factors have also been studied as predictors of employee performance in organizations. However, studies that comprehensively measured all the dimensions of employee performance that enhance organizational effectiveness are limited. This paper explored the influence of HRM practices on the employee performance in the Nigerian public sector. Using cross sectional method on 265 participants from local government areas, the findings revealed that HRM practices such as job rotation, job autonomy and career planning had a significant and positive influence on all the three dimensions of employee performance (task, contextual and adaptive performance).
Resource-Constrained Project Scheduling Problem (RCPSP) is considered as an important project scheduling problem. However, increasing dimensions of a project, whether in number of activities or resource availability, cause unused resources through the planning horizon. Such phenomena may increase makespan of a project and also decline resource-usage efficiency. To solve this problem, many methods have been proposed before. In this article, an effective backward-forward search method (BFSM) is proposed using Greedy algorithm that is employed as a part of a hybrid with a two-stage genetic algorithm (BFSM-GA). The proposed method is explained using some related examples from literature and the results are then compared with a forward serial programming method. In addition, the performance of the proposed method is measured using a mathematical metric. Our findings show that the proposed approach can provide schedules with good quality for both small and large scale problems.
Retaining the best employees is of high concern for most organizations and this issue has become a significant focus of attention for many researchers. For this reason, this paper discusses different factors which influence the employee turnover intention-behavior in the organization, specifically to examine the effect of salary, performance appraisal, training & development and career growth on turnover intention. In addition, based on the social exchange theory this paper explains the mediating role of organizational commitment in the relationship between human resource development factors, career growth and turnover intention. A cross sectional, survey data study is undertaken to investigate the relationships in a sample of 270 full time faculty members employed in different private universities of Pakistan. Partial Least Square two step path modeling is used to test the direct and the indirect hypothesis of the study. The results of PLS (SEM) path modeling reveal that human resource development factors specially salary and performance appraisal were negatively associated with turnover intention. In addition, the results also indicate that career growth had significant relationships with turnover intention. Moreover, out of four dimensions of career growth, only two dimensions, namely promotion speed and remuneration growth, have strong influence on turnover intention. Finally, in terms of organizational commitment as mediating variable between the relationships of salary, performance appraisal, career growth and turnover intention, four out of six variables indicate partial mediation including career growth (career goal progress), career growth (promotion speed), career growth (remuneration growth) and performance appraisal.
Employee productivity is one of the important management topics that received significant research attentions from several scholars and considered as a primary mechanism to enhance organizational success. Knowing what are the key factors that influence productivity is vital to ensure long term performance. This study examines the effect of work engagement on employee productivity in higher education sector. To accomplish this purpose, the primary data using survey instrument were collected from a sample of 242 employees at public universities in northern Malaysia using an online survey method. The collected data was analyzed using SPSS and Structural equation modelling on AMOS. The results indicated that work engagement had significant positive effect on employee productivity. Moreover, this study provides an evidence that all of the dimensions of work engagement namely vigor, dedication, and absorption have significant positive effects on employee productivity.
This study empirically investigates the mediating effect of brand satisfaction on the relationship between brand personality and brand loyalty among Malaysian customers toward local automobile brands (Proton and Perodua). Four hypotheses were developed to test hypothesizing relationships between brand personality and brand satisfaction on brand loyalty. The data were collected from consumers of automobile brands in north Malaysia peninsula from three states which were Kedah, Penanag, and Perlis. This study applies partial least squares to a sample of 458 customers to test hypothesized relationships. The findings indicate that brand personality and brand satisfaction appear to have a positive and significant relationship with brand loyalty. Moreover, brand satisfaction was found to be a mediator in the relationship between brand personality and brand loyalty. The results are compared with earlier findings and implications for further research are discussed.
The aim of this study is to establish a framework for measuring and managing credit risk for fifteen leasing companies in Iran. An analysis on the influence of internal factors on credit performance will then be performed. This will enable a leasing industry to progress towards its goals and objectives in the most direct and effective way. Credit risk consists of probability of non-return. This may be in the form of bankruptcy or a decrease in financial and credit situation of the lessee. We can assume a correlated market and credit risk. The variables are extracted from the Central Bank of Kanoon Leasing Association in Iran. Numerical analysis reveals that lessee credit risk can have a substantial impact on a lease term structure.
