Abstract
Security in sensor networks is more important than traditional networks as they are deployed in hostile environments and are more prone to capture. Trusted third party authentication schemes, public‐key systems are not suitable owing to their high resource requirements. Key pre‐distribution was introduced in (3) to solve this problem. Our scheme achieves identical connectivity compared to the random key pre distribution (4) using a less number of preloaded keys in each sensor node. The design of our scheme is motivated by the observation that at present most key pre‐distribution schemes employ random mechanisms which use a large number of keys and are unsuitable for sensor networks. In this paper we extend the deterministic key pre‐distribution scheme proposed by us in our earlier work (1), which is based on assigning keys to sensors by placing them on a grid. This approach has been further modified to use multiple mappings of keys to nodes. In each mapping every node gets distinct set of keys which it shares with different nodes. The key assignment is done such that, there will be keys in common between nodes in different sub‐grids. After randomly being deployed, the nodes discover common keys, authenticate and communicate securely. The analysis and simulation results show that this scheme is able to achieve better security compared to the random schemes.

Abstract
Purpose
The purpose of this paper is to reinterpret Attali’s worldview through the lenses of liberalism and Buddhism by mobilizing the relevant literature, beyond the mere book review. This paper is an essay based on the book “Devenir Soi” by Jacques Attali, published in France in 2014. These analytical grids were chosen, because freedom and self-realization are two themes that pervade the book.
Design/methodology/approach
After presenting the book structure, the objective and the methodological approach, we uncover Attali’s interrogation, namely how to free oneself from the omnipresence of evil, the withering away of the State and growing xenophobic populist self-entitlement. We make explicit Attali’s liberalism and plea for freedom, and we present a critical discussion of his method, based on the idea of selfness essentialism and a novel comparison with Buddhism. Finally, we assess the overall success of Attali’s intellectual endeavor.
Findings
Attali’s thesis is generally consistent and solid. Nevertheless, a few weaknesses are identified.
Practical implications
Anybody willing to read Attali’s book as a self-development book will gain some valid insights with this paper.
Social implications
Attali’s book is largely centered on the individual. Yet, through the lenses of liberalism and Buddhism, a new vision of society is put forward.
Originality/value
Attali enjoys an international reputation as an intellectual, economist and essayist. Devenir Soi has not yet been translated in English. More than a mere translation, the present paper will bring his ideas to the fore in the English-speaking world.

Abstract
As the Rohingya minority is expelled from their native society, many families have migrated to India where they face societal, legal, and educational discrimination due to lack of transactional relationship with the Indian state. This study aims to understand how the schooling of Rohingya children in the Kalindi Kunj’s Myanmar Refugee Camp in the city of New Delhi (India) is associated with the aspirations of the children and of their parents in the face of cultural disruptions in the socialization of the children. This ethnographical study is based on the narratives of both children and their parents from the Rohingya refugee community as a tool to capture their life-worlds.

Abstract
Unfortunately in India, most landfills are located along the banks of rivers flowing through the cities. The interaction of two big, diverse and delicate ecological systems – rivers and landfills – has been investigated in this paper. During 2000, the estimated quantity of waste generation was more than 9,000 tons per day. This is one of the biggest sources of environmental degradation in Delhi, India's capital. It contributes to river pollution in a significant way through landfill leachate and runoff, especially during the rainy season. Since the 1950s over 12 large landfills have been packed with all sorts of non‐biodegradable and toxic wastes from Delhi. The area covered by landfills is at least 1 percent (14.83 sq.km) of Delhi's total area. All the landfill sites except Tilak Nagar, Hastal and Chattarpur are located close (0‐6 km) to the river Yamuna. Further, these landfills are not engineered sanitary landfills and the waste is dumped at open sites without proper compaction. A high mountain of waste can be seen at all landfill sites without a cover. The leachate produced by landfills finally percolates to the porous ground surface at the landfills or finds its way to nearby drains. A large portion of landfill leachate and runoff produced by these landfill sites finally reaches the Yamuna through ground water flow or surface water flow through the drains. The results of analysis by investigations and environmental mapping during the study clearly indicate that river water quality is affected by the presence of landfill locations, i.e. landfill leachate and landfill surface runoff.

Abstract
Purpose
The purpose of this paper is to present an overview of trends of Indian information technology and business processing management (IT-BPM) sector and to analyse the determinants of IT-BPM sector during the period 1991-2014.
Design/methodology/approach
The study is based on annual data collected from National Association of Software and Service Companies and Department of Electronic and Information Technology for the period 1991 to 2014. The methodology adopted for studying the objectives are simple averages, percentages, ratios, growth rates, graphs prepared on the basis of data from the IT-BPM sector and regression analysis. Trends and patterns in key variables, such as total revenue, domestic revenue, export revenue, employment and exports of the IT-BPM sector have been examined. Factors influencing IT-BPM export growth have been analysed using ordinary least square multiple regression model, with growth rates of gross domestic product (GDP), labour productivity, exchange rate and previous year’s export, as the explanatory variables.
Findings
The export revenue from IT-BPM sector increased continuously over the years, at an average growth rate of 36.60 per cent during the period 1991 to 2014. Similarly, domestic revenue of IT-BPM sector also increased, but at a lower growth rate. This is because domestic market in India is captured by multinational giants against Indian firms, which do not possess full comparative advantage in the case of IT-BPM sector. Indian firms are producing low skill activities required for production, mainly concentrated only in the export sector. Direct employment, excluding hardware from IT-BPM sector, has grown at an average rate of 18.08 per cent over the study period. The determinants of IT-BPM exports indicated previous year’s export demand to be significantly contributing the highest to export growth rate. This was followed by GDP growth rate, implying that overall growth of the economy leads to significant increase in export growth. Increased labour productivity followed next in significantly encouraging export growth.
Research limitations/implications
Generalization of the results may not be possible, as Indian conditions and policies vary.
Practical implications
The paper has implications for the expansion of domestic market, diversification of trade and products, innovations for increasing competitiveness and sustainability in the global market in the wake of stiff competitions from new competitors.
Originality/value
This paper focuses on originality in analysis of determinants of export growth.

Abstract
Purpose
The enrolment rates of students with special needs (SwSN) decrease from primary to secondary education and decline steeply in higher education. The incessant impact of stigma and misconceptions about their capability in academic performance acts as a major roadblock for students with mental health conditions (SwMHC) while seeking and pursuing higher education, in addition to the host of other challenges faced by all SwSN. SwMHC are the least represented in higher educational institutions (HEIs) and are seldom considered when it comes to the provision of support and accommodation. Policies across countries aim to make education accessible and inclusive for SwSN, including India. This study aims to appraise the current policies and legislation in terms of the support they provide for SwMHC.
Design/methodology/approach
This study is a “document analysis” of all policies, legislation, schemes and guidelines that impact the higher education of SwMHC to recognize the existing provisions that are likely to impact the higher educational outcomes for SwMHC.
Findings
The issues of access, accommodation, equity, inclusion, and financial support are appropriately handled by the current policies and legislation. The National Education Policy (NEP) 2020 serves as a holistic guidebook and the Rights of Persons with Disabilities Act (RPDA) 2016 provides the legislative framework for realizing education as a ‘right for all.’ The RPDA ensures open gateways of HEIs for all SwSN through reservations and mandating necessary support and accommodation. NEP guides inclusion and equity in higher education. The ‘University Grants Commission’, an autonomous body under the Ministry of Education, is a crucial stakeholder in achieving the vision of supportive policies by formulating requisite guidelines and monitoring their implementation.
Originality/value
The study involved document analysis spanning macro to micro level, i.e. from national policies and legislation to policies and guidelines of autonomous or statutory organizations to institutional-level policies and documents.

Abstract
Purpose
The aims of the paper are to investigate IT software and service export function for India. First, cointegration tests have been used to investigate the long-run equilibrium relationship of the given variables. Second, long-run coefficients and associated error correction mechanism are estimated.
Design/methodology/approach
Annual time series data on IT software and service exports, human capital, exchange rate, investment in IT, external demand and openness index have been used for the present study during the period 1980–2017. The data are collected from the National Association of Software and Service Companies (NASSCOM), Planning Commission of India, University Grants Commission (UGC) of India, real effective exchange rate (REER) database and World Bank development indicators. Auto regressive distributed lag (ARDL) model is used to analyze both short-run and long-run dynamic behaviour of economic variables with appropriate asymptotic inferences.
Findings
Results of the analysis show the stable long-run equilibrium relationship among the given variables. It is found that external demand, exchange rate, human capital and openness index have a substantial long-run impact on the IT software and service exports. We also found that the coefficient of error correction term is negative and significant at 1% of the level of significance, which confirms the existence of stable long-run relationship which means adjustment will take place when there is a short-run deviation to its long-run equilibrium after a shock.
Research limitations/implications
There may be other determinants of software and service exports apart from those considered by the present study. Due to the non-availability of data, the study considers only important determinants that determine the software and service exports in India. The IT exports are an emerging and dynamic field of economic activity and the rate of change is so rapid that the relevance of individual factors may change over time. The study period is also limited to available data.
Practical implications
The paper has implications for achieving sustainability in IT software and service exports growth. It is recommended that policies directed at improving the performance of IT software and service exports should largely consider the long-run behaviour of these variables.
Originality/value
This paper focuses on originality in the analysis of the relationship among the given variables including IT software and service exports, human capital, exchange rate, investment in IT, external demand and openness index in India. All the work has been done in original by the authors, and the work used has been acknowledged properly.

Abstract
This introductory chapter provides an overview of the ways that refugee and forced im/migrant (RFI) youth move across time and context in their educational experiences. In particular, the contextual characteristics of determinism, duration, and mobility are explained, and the factors most often associated with RFI youth educational experiences (i.e., trauma, identity, and language) are discussed in reference to the ways that educational infrastructure, capacity, and sustainability are typically established and maintained in educational situations worldwide. This chapter also provides a brief overview of the volume’s chapters and the ways that each chapter addresses one or more of these themes or topics.
