Abstract

Purpose

The purpose of this study is to assess the key determinants of green human resource management (GHRM) and investigate its impact on environmental performance (EP) and business performance (BP).

Design/methodology/approach

The research employed SmartPLS 3 and follows a cross-sectional research design. Data from 179 employees were collected using a convenience sampling technique from the firms that adopted GHRM practices.

Findings

The research found a significant relationship of GHRM with EP and also reported the significant relationship between EP and BP. Moreover, EP significantly mediates the relationship of GHRM with BP.

Research limitations/implications

A relatively small sample size of employees was used that may suggest the need for a diverse and more representative sample. The paper is based on data collected from the Malaysian manufacturing industry – other economic sectors and Asian countries may offer different results.

Practical implications

The paper identifies the need for incorporating GHRM practices and culture at the workplace to encourage positive green behavior in employees which will increase the EP and BP of the firm.

Originality/value

This paper reported the initial empirical findings after the March 7th incident on EP of businesses in Malaysia, where businesses have initiated the adoption of GHRM practices.

Abstract

Purpose

The purpose of this study was to determine how environmentally specific transformational leadership (ETFL), green training (GT) and psychological green climate (PGC) affect environmental passion (EP) of employees which leads to pro-environmental behaviors (PEBs).

Design/methodology/approach

The context of the study was set in textile industry of Pakistan which holds a promising future in the international markets as an emerging export-based industry. Using purposive sampling technique, cross-sectional self-report data were collected from the employees of textile exporting firms (n = 239) of Pakistan. Hypotheses were tested using PLS-SEM.

Findings

The findings revealed that ETFL and PGC act as important predictors of EP, whereas GT plays no role in influencing EP. EP predicts green behavioral intention (GBI) of employees, in turn, GBI predicts employees' PEBs. Further, mediation analyses revealed that EP and GBI sequentially mediated the link between PGC and PEBs.

Research limitations/implications

The present study is not free from its limitations. First, the study adopted cross-sectional design that prevents the causal inferences which the researcher can make from the population. Second, the present study adopted purposive sampling technique which is a non-probability sampling technique. Third, the constructs of this study were assessed with self-report measures which are associated with social desirability bias (Podsakoff and Organ, 1986) or common-method variance (Podsakoff et al., 2003). Hence, this research suggests on the future direction of research based on these limitations.

Practical implications

As per the results of this study, it is also suggested that managers may focus more on the overall organizational and psychological climate rather than on leadership styles alone. While conducting training, the leaders must pay close attention to training objectives to ensure that they do not lead to counterproductive behaviors.

Originality/value

This research adds to the literature in the area of PEBs at micro-level by focusing on how and why employees engage in PEBs.

Abstract

Purpose

The paper aims to investigate the determinants of workplace innovation behavior of women employees in Pakistan. With a growing share of women's participation in the labor force in developing economies, it is crucial to understand their behavior. The authors looked into various practices that drive women's innovative behavior using social exchange theory (SET) as a theoretical framework.

Design/methodology/approach

This study is quantitative-based on the positivistic paradigm. Following the survey method technique, responses are collected from 317 female employees in the service industry. The authors used structural equation modeling for the data analysis.

Findings

The results indicate a significant impact of leader-member exchange (LMX) on employee empowerment; schedule flexibility was also a possible predictor of workplace innovation behavior through mediating roles of employee empowerment and response to change. The study findings are consistent with the prior literature and according to the developed hypothesis. Further, women's response to change partially mediates women employees' empowerment and workplace innovation behaviors. In addition, LMX significantly affects women's response to change through women employees' empowerment, leading to workplace innovation behavior.

Practical implications

The implication is that supervisors should be adaptable in working relationships with their women employees to bring positive workplace innovative behaviors. They create such exchanges with employees to make them feel that the organizations value them. The paper identifies the need to develop supportive supervisor-employee exchange relationships to encourage positive, innovative behavior in female employees.

Originality/value

This paper examines the workplace innovation behavior of women employees in Pakistani patriarchal society and a male-dominating workplace environment.

Abstract

Purpose

The purpose of this study is to provide the full-state mathematical model and devise a nonlinear controller for a balloon-supported unmanned aerial vehicle (BUAV).

Design/methodology/approach

Newtonian mechanics is used to establish the nonlinear mathematical model of the proposed vehicle assembly which incorporates the dynamics of both balloon and quadrotor UAV. A controllable form of the nine degrees of freedom model is derived. Backstepping control is designed for the proposed model and simulations are performed to assess the tracking performance of the proposed control.

Findings

The results show that the proposed methodology works well for smooth trajectories in presence of wind gusts. Moreover, the final mathematical model is affine and various nonlinear control techniques can be used in the future for improved system performance.

Originality/value

Multi-rotor unmanned aerial vehicles (MUAVs) are equipped with controllers but are constrained by smaller flight endurance and payload carrying capability. On the contrary, lighter than air (LTA) aerial vehicles have longer flight times but have poor control performance for outdoor operations. One of the solutions to achieve better flight endurance and payload carrying capability is to augment the LTA balloon to MUAV. The novelty of this research lies in full-order mathematical modeling along with transformation to controllable form for the BUAV assembly.

Abstract

Purpose

This paper aims to investigates a novel design of a modular moving magnet linear oscillating actuator (MMM-LOA) with the capability of coupling modules, based on their application and space requirements.

Design/methodology/approach

Proposed design comprised of modules, and modules are separated by using nonmagnetic materials. Movable part of the proposed design of LOA is composed of permanent magnets (PMs) having axial magnetization direction and tubular structure. Stator of the proposed design is composed of one coil individually in a module. Dimensions of the design parameters are optimized through parametric analysis using COMSOL Multi Physics software. This design is analyzed up to three modules and their response in term of electromagnetic (EM) force and stroke are presented. Influence of adding modules is analyzed for both directions of direct current (DC) and alternating input loadings.

Findings

Proposed LOA shows linear increase in magnitude of EM force by adding modules. Motor constant of the investigated LOA is 264 N/A and EM force per PM mass is 452.389 N/kg, that shows significant improvement. Moreover, proposed LOA operates in feasible region of stroke for compressor application. Furthermore, this design uses axially magnetized PMs which are low cost and available in compact tubular structure.

Originality/value

Proposed LOA shows the influence of adding modules and its effect in term of EM force is analyzed for DC and alternating current (AC). Moreover, overall performance and structural topology is compared with state-of-the-art designs of LOA. Improvement with regard of motor constant and EM force per PM mass shows originality and scope of this paper.

Abstract

Purpose

This paper aims to devise a robust controller for the non-linear aircraft model using output feedback control topology in the presence of uncertain aerodynamic parameters.

Design/methodology/approach

Feedback linearization-based state feedback (SFB) controller is considered along with a robust outer loop control which is designed using Lyapunov’s second method. A high-gain observer (HGO) in accordance with the separation principle is used to implement the output feedback (OFB) control scheme. The robustness of the controller and observer is assessed by introducing uncertain aerodynamics coefficients in the dynamic model. The proposed scheme is validated using MATLAB/SIMULINK.

Findings

The efficacy of the proposed scheme is authenticated with the simulation results which show that HGO-based OFB control achieves the SFB control performance for a small value of the high-gain parameter in the presence of uncertain aerodynamic parameters.

Originality/value

A HGO for the non-linear model of aircraft with uncertain parameters is a novel contribution which could be further used for the unmanned aerial vehicles autopilot, flight trajectory tracking and path following.

Abstract

Learning outcomes

The learning outcomes are as follows: what tasks are to be done by medical representatives in pharmaceutical industry? This study also highlights various competencies required to do effective selling in this industry; analyzes and discusses different unethical practices going on in the market; explains why ethical norms are necessary in sales context when sales targets are already achievable with unethical means; and develops and comments on strategies Flori Pharmaceutical can make to overcome on these unethical issues. What should be the response of Dahar to the email of Naveed khan? What course of action should be taken by Dahar in the deceitful reporting case of Mohsin Ali?

Case overview/synopsis

Flori is considered a leading and growing multinational organization in the highly competitive environment of Pakistan pharmaceutical industry with over 40 years of experience. The company aims to command a leading position in developing new health-care products as it offers a wide range of diabetic, cardiovascular, respiratory and vitamin products based on quality as a result of high research and examination. Recently, an email to Bilal Dahar on March 2017 from Flori’s star sales person Naveed Khan has forced management to take some strong decisions regarding ethical norms and values to be adopted by medical representatives of Flori pharmaceuticals. The email highlighted the issues related to sales pressure which are leading toward unethical sales practices. Dahar just not have to maintain Flori’s ethical code of conduct but he and his team also has to work hard to achieve more than 26% growth rate in sales revenue as compared to last year. Dahar knew that the highly competitive environment of pharmaceutical industry has led most of the stake holders to indulge in unethical behavior to achieve their individual targets. He knew that this is dangerous in long term for the multinational organizations such as Flori pharmaceuticals as if the similar behavior continues, the sales culture and values of the organization would be on stake. He also has to decide what decision to be taken against deceitful reporting issue of one of the top-performer territory managers, who was key person in helping Flori to close the sales year 2016 with the revenue of Rs. 6.4bn, a 26% growth over the last year. The case is rich enough to provide a platform regarding management of several ethical challenges in pharmaceutical selling and developing strategies based on them.
