Abstract
Purpose
This paper aims to propose a novel splicing detection method using a discriminative robust local binary pattern (DRLBP) with a support vector machine (SVM). Reliable detection of image splicing is of growing interest due to the extensive utilization of digital images as a communication medium and the availability of powerful image processing tools. Image splicing is a commonly used forgery technique in which a region of an image is copied and pasted to a different image to hide the original contents of the image.
Design/methodology/approach
The structural changes caused due to splicing are robustly described by DRLBP. The changes caused by image forgery are localized, so as a first step, localized description is divided into overlapping blocks by providing an image as input. DRLBP descriptor is calculated for each block, and the feature vector is created by concatenation. Finally, features are passed to the SVM classifier to predict whether the image is genuine or forged.
Findings
The performance and robustness of the method are evaluated on public domain benchmark data sets and achieved 98.95% prediction accuracy. The results are compared with state-of-the-art image splicing finding approaches, and it shows that the performance of the proposed method is improved using the given technique.
Originality/value
The proposed method is using DRLBP, an efficient texture descriptor, which combines both corner and inside design detail in a single representation. It produces discriminative and compact features in such a way that there is no need for the feature selection process to drop the redundant and insignificant features.

Abstract
Purpose
Green human resource management (GHRM) and sustainable green logistics (SGLOG) are some of the mechanisms by which sustainable corporate environmental management could be consummated. However, prior studies linking GHRM and green logistics are lacking in the literature. This paper extends prior efforts by developing a model linking GHRM and SGLOG.
Design/methodology/approach
An integrative review of extant literature on green human resource management and sustainable green logistics was conducted, and an integrative model developed.
Findings
Improving environmental performance is a key way that businesses can improve their corporate social responsibility and brand image. The resulting model includes expanded components of GHRM (training, development, compensation, awards and recognition, recruitment, and performance management) and of SGLOG (transportation and shipping, warehousing, packaging, and reverse logistics). Categories of shipping and transportation include the following facets: transportation intensity, modal split, emissions intensity, energy efficiency, and vehicle utilization efficiency. The model also highlights the mediating role of management and employee attitudes, knowledge, and skills in the GHRM-SGLOG link, as well as their interaction.
Research limitations/implications
Green human resource management is associated with sustainable green logistics. This association is theoretically mediated by management and employee attitudes, knowledge, and skills. Top management support and influence of other stakeholders are key facilitators.
Practical implications
The paper suggests potential barriers to GHRM and SGLOG adoption/diffusion and panaceas. It also proposes some key drivers of sustainable green logistics and corporate environmental management.
Firms must carry out their operations in ways that do not compromise societal and environmental well-being. High economic performance alone no longer suffice. A balanced performance that also emphasizes social and environmental well-being (the triple bottom line, 3BL) can be achieve through the implementation of the proposed model.
Originality/value
The integrative model presented in the paper advances the current understanding of the link between GHRM and SGLOG. The paper adds additional value by unveiling some key future research directions.

Abstract
Purpose
Drawing upon conservation of theory, this study aims to extend the scant literature on the effect of leader-member exchange (LMX) on workplace deviance behaviour (WDB) and adaptive performance by investigating the role of Islamic work ethics as moderators.
Design/methodology/approach
A time-lagged and multi-source data of (269 paired responses) of employees working in Islamic banks were used for hypotheses testing.
Findings
Taken together, the findings revealed that Leader Member Exchange (LMX) has a positive and significant impact on adaptive performance and is negatively related to employees’ WDB. The results of the moderation effect showed the positive relationship of LMX with adaptive performance and the negative relationship with WDB is stronger for high Islamic work ethics (IWE).
Practical implications
This study provides practical insight that Islamic business ethics plays a significant role in fostering adaptive performance and reducing the deviance behaviour of employees.
Originality/value
To the best of the authors’ knowledge, this is the first study that examined the moderating role of IWE between LMX-adaptive performance and LMX-WDB. This study has also filled the gap of scant literature about the impact of LMX on adaptive performance and WDB.

Abstract
Purpose
This study aims to investigate the impact of psychological contract fulfillment (PCF; independent) on organizational citizenship behavior (OCB; dependent) with perceived organizational support (POS) playing a partial mediating role.
Design/methodology/approach
Quantitative methodology has been adopted to achieve the aim of this study, and data were collected via a questionnaire through an employee–supervisor/colleague dyad. Various five- and four-star hotel staff members in Pakistan were the target population, eliciting a recorded sample of 418 employees and 105 supervisors/colleagues.
Findings
The study revealed that PCF has a positive impact on POS and OCB. The partial mediating role of POS between the dependent and independent variables was also confirmed.
Research limitations/implications
Among the implications, a novel theoretical underpinning of organizational support theory (OST) was established in psychological contract literature in addition to the social exchange theory (SET). Similarly, the mediating mechanism of POS was also validated, thereby offering an additional extension in psychological contract literature. Among the limitations, the cross-sectional nature of data and testing of a single mediating path between independent and dependent variables can be noted.
Originality/value
Alternative theoretical underpinning, that is, the usage of OST, the partial mediating role of POS and the study settings, i.e. evidence from the hotel industry from a developing country, are novel contributions of this study.

This study examines the initiatives that would enable contractors in Singapore to improve the level of construction productivity.
Abstract
Purpose
This study examines the initiatives that would enable contractors in Singapore to improve the level of construction productivity.
Design/methodology/approach
A two-pronged research method was employed: questionnaire survey with contractors (109 responses received) and in-depth interviews with 12 subject matter experts. The questionnaire covered questions such as the current and future improvement measures.
Findings
The results show that the top three motives for achieving high productivity (increase profitability, on time delivery and enhance corporate competitiveness) are underpinned by profit maximization. Factor analysis revealed several categories of productivity improvement strategies. Among these, only site operations category is under the control of contractors. Other important categories include government's initiatives and design factors.
Research limitations/implications
While contractors are the producers of built products, their productivity is very much dependent on other factors and other parties. The long-standing exhortation to contractors to improve productivity is necessary but not a sufficient condition to improve it.
Practical implications
Recommendations are provided for the government, designers, contractors and other stakeholders on what can be done to improve productivity.
Originality/value
This research adds to knowledge by showing that contractors' top motives for high productivity relate to self-seeking behavior to maximize profit. Prior to this study, productivity improvement is considered the responsibility of contractors. This study shows that two other stakeholders also hold the key to productivity improvement – government and designers. Government controls the supply of foreign labor, has the capacity to offer incentives and has the muscle to enact regulations to improve productivity. Consultants' upstream designs must be buildable.

Abstract
Purpose
The existence of intense competition in turbulent markets confirms the importance of using ethical employee practices in knowledge sharing behaviour (KSB) to ensure organisational growth. This is especially applicable in developing countries' markets where this intensive competition usually results in organisations following illicit practices. This paper aims to examine the relationship between the Big Five personality traits (i.e. openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism) and KSB using Islamic work ethics (IWE) as the moderator.
Design/methodology/approach
A quantitative research method using a survey instrument collected 182 responses from employees in the Pakistani telecommunication industry. The partial least squares structural equation model (PLS-SEM) was used to analyse the collected data.
Findings
The results found that IWE has a positive impact on KSB and a positive moderating impact on the relationship between the Big Five personality traits except neuroticism and KSB. Also, openness to experience and agreeableness positively impacted KSB.
Practical implications
This paper contributes to the field of human resource (HR) management by helping managers in the hiring process or developing employee's personalities. Additionally, policymakers are encouraged to create Islamic values platforms to increase KSB amongst employees.
Originality/value
This study indicates the importance of IWE in boosting the impact of personality on KSB and provides insights into IWE's role in enhancing an organisation's competitive advantages in turbulent markets.

Abstract
Purpose
The aim of this paper was to prepare a stable fluorescent disperse yellow paste by wet grinding process by adding naphthalene sulphonic derivative dispersing agent.
Design/methodology/approach
The dispersants 2-naphthalenesulphonic acid (NNO), naphthalene-sulphonic acid (MF) and benzyl naphthalene sulphonate formaldehyde condensate (CNF) were used to disperse the yellow dye. The particle size of the paste was characterised by particle size analyser. The paste centrifugal stability, diffusion properties, morphology and thermal properties were also tested for assessing its stability which could be helpful to prepare inks with good stability.
Findings
The particle sizes of dye pastes with dispersing agent NNO, MF and CNF were 161.1, 150.0 and 136.0 nm, respectively, after grinding for 6 h. The dye paste grinded with dispersing agent CNF presented good centrifugal and thermal properties. TEM images demonstrated that the morphologies of dye pastes grinded with dispersing agent MF and CNF were homogeneous nearly spherical nanoparticle and rarely generated agglomeration and precipitation.
Originality/value
The paste used for aqueous inkjet ink exhibited excellent thermal stability.

Abstract
Purpose
With rapidly changing marketing landscape, nowadays, the formulation of various marketing strategies is increasingly focused on how consumers tend to make decisions. To meet the highly demanding consumer expectations, market segmentation can be used as an important marketing strategy. Due to gender marketing concept familiarity in the contemporary world, gender difference is one of the reference features in the process of market segmentation for marketers. This research is aimed to examine various determining factors that foster consumer purchase decision-making and the differences between consumers of different genders while making shopping and purchase decisions with special reference to an emerging economy, i.e. Pakistan.
Design/methodology/approach
Based on a cross-sectional sample of 367 consumers, the study adapted Sproles and Kendall's (1986) Consumer Style Inventory (CSI) to scrutinize the decision-making of both genders in Pakistan. For data analysis, the exploratory and confirmatory factor analysis in addition to the structural equation modeling has been used.
Findings
The study emphasized that, with the exception of quality awareness, brand consciousness, fashion consciousness, option overload and price consciousness greatly affect buying decisions. In addition, when it comes to consumer purchase decision-making, significant gender variations were discovered for both fashion consciousness and price consciousness.
Originality/value
Drawing upon the distinctive cultural characteristics of Pakistan and its people, in-depth research was conducted on purchasing behaviors of Pakistani consumers and the decision-making characteristics of customers of different genders were summarized. The outcomes are expected to make a significant contribution to the field of gender marketing by organizations.

Abstract
Purpose
This study aims to explore the associations between leadership styles (i.e. transformational and ethical) and innovative work behavior within higher education institutions (HEIs), additionally investigating the mediating role of work engagement and the moderating role of psychological empowerment.
Design/methodology/approach
The basis of this study rested upon adopting a cross-sectional research framework. The data were acquired from a sample comprising 825 academic staff and 275 leaders across 226 HEIs in China. Employing a quantitative methodology, the researchers used AMOS version 26.0 and SPSS version 22.0 for statistical analysis.
Findings
The results indicated that leadership styles (i.e. transformational and ethical) positively affected innovative work behavior, both directly and indirectly (via work engagement). Also, psychological empowerment moderated the linkage between leadership styles and innovative work behavior but not the association between work engagement and innovative work behavior.
Originality/value
Despite some existing literature having discussed the correlation between leadership styles and innovative work behavior, there appears to be a conspicuous dearth of research endeavoring to explore the mediator (i.e. work engagement) and the moderator (i.e. psychological empowerment) within the above nexus, especially in the context of HEIs. Thus, this study can be considered original, introducing novel perspectives and substantial contributions to the management literature on HEIs. In addition, it offers insights for organizational managers.
