Abstract
Purpose
Routing protocol for low-power lossy network (RPL) being the de facto routing protocol used by low power lossy networks needs to provide adequate routing service to mobile nodes (MNs) in the network. As RPL is designed to work under constraint power requirements, its route updating frequency is not sufficient for MNs in the network. The purpose of this study is to ensure that MNs enjoy seamless connection throughout the network with minimal handover delay.
Design/methodology/approach
This study proposes a load balancing mobility aware secure hybrid – RPL in which static node (SN) identifies route using metrics like expected transmission count, and path delay and parent selection are further refined by working on remaining energy for identifying the primary route and queue availability for secondary route maintenance. MNs identify route with the help of smart timers and by using received signal strength indicator sampling of parent and neighbor nodes. In this work, MNs are also secured against rank attack in RPL.
Findings
This model produces favorable result in terms of packet delivery ratio, delay, energy consumption and number of living nodes in the network when compared with different RPL protocols with mobility support. The proposed model reduces packet retransmission in the network by a large margin by providing load balancing to SNs and seamless connection to MNs.
Originality/value
In this work, a novel algorithm was developed to provide seamless handover for MNs in network. Suitable technique was developed to provide load balancing to SNs in network by maintaining appropriate secondary route.

Abstract
Purpose
This study aims to look at the integration of gamification in an e-learning model based on the technology acceptance model. The data was collected from respondents residing in India and elements of gamification (achievement, immersion and social) and personal characteristics of learners (self-efficacy, computer anxiety and enjoyment) and their impact on perceived ease of use (PEOU) and perceived usefulness (PU) were tested.
Design/methodology/approach
The data were collected from students and professionals who have ever played games during learning while using an e-learning module. Structural equation modeling using smart partial least square was used to create a model.
Findings
The findings showed that enjoyment affected both PEOU and PU and attitude toward e-learning. Achievement and social elements impacted attitude and the immersion element moderated the relation between enjoyment and PEOU and PU. These finally impact attitude and satisfaction, leading to higher intention to use e-learning platforms.
Research limitations/implications
Because this study is very specific to the Indian context, a broad generalization requires further exploration in other cultural contexts. The absence of this exploration is one of the limitations of this study.
Originality/value
This study tested the GAMEFULQUEST suggested by Högberg et al. (2019) based on self-determination theory and its impact on the overall e-learning experience. The moderation of immersion has come out to be significant and achievement and social elements impacted attitude.

Abstract
Purpose
This paper analyses the role of green human resources management (GHRM) practices on the application of logistics social responsibility (LSR) practices and examines the moderating effect of big data analytics (BDA) utilisation levels within these relationships.
Design/methodology/approach
Based on quantitative research methodology using survey data from 404 managers in the logistics service providers (LSPs) industry in the Philippines, PLS-SEM technique was used to test hypotheses formulated in this research.
Findings
Empirical results achieved suggest that GHRM practices have a significant positive impact on LSR. Among all individual GHRM practices, green training and development did not have any influence on LSR. While the results also revealed that BDA assimilation acts as a moderator of the relationship between GHRM and LSR, no support was found for the moderation effect of BDA acceptance or adoption on this relationship.
Originality/value
The study fills a gap in the logistics literature by introducing dynamic capabilities theory to the nexus between GHRM and SLR for the first time, which reveals previously unknown answers on effects of GHRM practices on LSR. The study also introduces BDA assimilation as an important moderator that can strengthen positive impact of GHRM on LSR.

Abstract
Purpose
Organizational culture has been identified as an important factor in increased employee commitment. Particularly during a shortage of skilled workers, commitment is a meaningful indicator of higher loyalty and retention. However, limited research has studied the relationship between organizational culture and commitment from a global perspective. Most research focuses on specific aspects of culture and examines the aspects' effects on commitment separately. The author's objective is to identify influential organizational culture's dimensions and assess dimensions' relationship to commitment holistically.
Design/methodology/approach
For this purpose, the author analyzed a data set with 241,648 participants from 9 industries in Germany. The survey captures individual attitudes toward certain aspects of organizational culture and assesses workers' commitment to their organizations.
Findings
The results of a linear regression show that all cultural dimensions considered, namely transformational leadership behavior, team cohesion, compensation, fairness and caring attitude, if well-developed, positively and significantly influence organizational commitment. Interestingly, team cohesion has the greatest effect on commitment, followed by transformational leadership behavior, compensation, caring attitude and fairness.
Originality/value
This paper aims to examine the relationship between organizational culture and commitment holistically, thereby revealing which aspects of corporate culture are particularly important for increasing workers' commitment.

Abstract
Purpose
The purpose of this paper is to examine the relationships of capacity/layout (CL), design (D), location, (L), hygiene (H), human resource management (HRM), food quality (FQ) and ambiance (A) in operations management strategies (OMS) and the direct and indirect effects of OMS on customer satisfaction (CS) and customer behavioral intentions (CBIs) that might affect income and, therefore, be influential regarding café-restaurants in Sulaimania in Iraq.
Design/methodology/approach
Data are collected through a survey questionnaire using a simple random sampling methodology from 254 customers of 46 casual café-restaurants. Methodology includes demographic analysis, factor analysis, structural equation modeling and mediation analysis.
Findings
Concerning relationships between structural and infrastructural elements of OMS, only CL and H influence HRM, D and H affect A, and H influences FQ. Regarding relationships between OMS and CS and CBIs, only L, HRM, FQ and A affect CS. Concerning the relationship between CS and CBIs, CS influences CBIs. Finally, given indirect effects of OMS on CS and CBIs, HRM mediates relationships between CL-CS and H-CS; FQ and A mediate relationships between H-CS; and CS mediates relationships between L-CBIs, FQ-CBIs and HRM-CBIs.
Research limitations/implications
The study that treats seven variables in OMS is limited to Sulaimania in Iraq. Thus, the findings cannot be generalized. The study might guide future studies about the way OMS elements forge CS and CBIs in café-restaurants where owners/managers develop credible strategic plans.
Originality/value
The study provides a unique insight into the hospitality industry in Iraq where studies among elements of OMS are few and far between.
