Abstract
Purpose
This paper aims to present a non-linear mathematical model-based routing protocol for wireless body area networks (WBANs). Two non-linear mathematical models for WBANs are used in the proposed protocols Model 1 and Model 2. Model 1 intends to improve the data transmission rate and Model 2 intends to reduce energy consumption in the WBANs. These models are simulated for fixed deployment and priority-based data transmission, and performance of the network is analyzed under four constraints on WBANs.
Design/methodology/approach
Advancements in wireless technology play a vital role in several applications such as electronic health care, entertainment and games. Though WBANs are widely used in digital health care, they have restricted battery capacity which affects network stability and data transmission. Therefore, several research studies focused on reducing energy consumption and maximizing the data transmission rate in WBANs.
Findings
Simulation results of the proposed protocol exhibit superior performance in terms of four network constraints such as residual energy, the stability of the network, path loss and data transmission rate in contrast with conventional routing protocols. The performance improvement of these parameters confirms that the proposed algorithm is more reliable and consumes less energy than traditional algorithms.
Originality/value
The Model 1 of the proposed work provides maximum data extraction, which ensures reliable data transmission in WBANs. The Model 2 allocates minimal hop count path between the sink and the sensor nodes, which minimizes energy consumption in the WBANs.

Abstract
Purpose
The foreign-born skilled immigrant population is growing rapidly in Canada but finding a job that utilizes immigrants’ skills, knowledge and experience is challenging for them. The purpose of this paper is to understand the self-perceived health and social status of skilled immigrants who were working in low-skilled jobs in the service sector in Ottawa, Canada.
Design/methodology/approach
In this qualitative study, semi-structured interviews with 19 high-skilled immigrants working as taxi drivers and convenience store workers in the city of Ottawa, Canada were analysed using a grounded theory approach.
Findings
Five major themes emerged from the data: high expectations but low achievements; credential devaluation, deskilling and wasted skills; discrimination and loss of identity; lifestyle change and poor health behaviour; and poor mental and physical health status.
Social implications
The study demonstrates the knowledge between what skilled immigrants expect when they arrive in Canada and the reality of finding meaningful employment in a country where international credentials are less likely to be recognized. The study therefore contributes to immigration policy reform which would reduce barriers to meaningful employment among immigrants reducing the impacts on health resulting from employment in low-skilled jobs.
Originality/value
This study provides unique insights into the experience and perceptions of skilled immigrants working in low-skilled jobs. It also sheds light on the “healthy worker effect” hypothesis which is a highly discussed and debated issue in the occupational health literature.

Abstract
Purpose
The study attempted to assess the food security status of urban agriculture households in Ghana and India. Also, the extent of urban agriculture participation and its effect on food security in Ghana and India were examined.
Design/methodology/approach
A total of 650 urban agriculture farmers were interviewed for this study in Ghana and India. Food security status of urban households was assessed by the use of the Household Food Insecurity Access Scale, whereas the determinants of the extent of urban agriculture and its effect on food security were analysed by the use of the heteroskedastic linear regression and the Seemingly Unrelated Regression models, respectively.
Findings
From the study on average, households in Ghana were mildly food insecure, but that of India was moderately food insecure. The results further revealed that various demographic, economic, institutional and health and nutrition factors differently influenced urban food security and urban agriculture. Also, the extent of urban agriculture participation positively influenced food security.
Originality/value
Several studies in Asia (India) and Africa (Ghana) on urban food security have been geographically limited to New Delhi, Mumbai and Greater Accra, with few studies in the Middle Belt of Ghana, and Bihar in India. Besides, there is a limited, rigorous, empirical study on the effect of the extent of UA on food security in Asia (India) and Africa (Ghana) individually and together. Moreover, we extend the frontiers of the methodological approach by applying the Seemingly Unrelated Regression (SUR) model to understand if the factors that affect food-security accessibility based on two food security accessibility tools are correlated.

Abstract
Purpose
This paper traces the historical evolution and growth trajectory of the automotive and farm equipment sector, which is a very significant entity of the Mahindra & Mahindra (M&M) group. The purpose of this paper is to understand and provide a pragmatic framework through which the authors can see what were the internal and external factors and the spirit of the contemporary times that led to the changes in the nature of the group.
Design/methodology/approach
The “Greiner curve” model has been applied to interpret the evolutionary growth of the group and strategic trajectory explaining characteristics in its different phases.
Findings
M&M initially went through its share of learning and grew through pragmatic and, orchestrated entrepreneurial risk. The group made a very successful transition from a proprietorship model to a professionally managed group. It is found that rapid growth has been possible through innovation led collaboration. The group is increasingly organizing its innovation activities around the development of responses to specific challenges.
Research limitations/implications
This study suffers from methodological limitations associated with a stage model that the estimated length of the time the organizations will stay in a phase is not known. It is unclear whether passage through all stages is necessary; or whether, in some circumstances, one or more stages may be omitted, and if variations in sequencing can occur. The data for the initial years was not available in primary form and the paper had to depend entirely on the secondary sources.
Practical implications
Various strategies adopted by the group from time to time have practical implications for Indian economy. The group has faced many challenges, but challenge-led collaboration-driven approach represents a new type of innovation process that contrasts with other methods of business strategies and provides a sharper focus for managerial and technical issues and brings together stakeholders with diverse interests, expertise and perspectives.
Originality/value
This study is a unique attempt in India to trace the evolution of the strategic interventions in the context of a major business group, which is considered to be a symbolic representation of Indian economic history. The paper has got both academic as well as managerial utility.
