The demand for aluminium alloys has been increasing in almost all the fields. In this study, the friction stir welding (FSW) of similar aluminium alloy AA 8011-h14 has been presented using three levels of tool rotational speed (n), tool tilt angle (ϴ) and tool feed (f). The purpose of this paper is to study the effect of welding parameters on various properties and time-temperature plots.

FSW was carried out using the L-9 orthogonal array of welding parameters generated using the Taguchi approach. Visual inspection and radiography testing were conducted to detect the surface and volume defects, respectively. Taguchi analysis was carried out to get optimised welding parameters for tensile testing. The microstructural analysis was carried out for the specimen possessing maximum tensile strength and the obtained grain structures were compared with the microstructure results of the base material. The peak process temperatures were noted and time-temperature plots were analysed for the varying parameters. The maximum value of hardness was recorded and analysed.

Visual inspection and radiography testing confirmed defect-free joints. The maximum tensile strength achieved was 84.44 MPa with 64.95 per cent efficiency. The optimised parameters obtained using Taguchi analysis for tensile testing were 1,500 rpm, 1° and 50 mm/min. Microstructure analysis for the specimen possessing maximum tensile strength revealed fine and equiaxed grains in the nugget zone. Time-temperature plots suggested the maximum temperature of 389 °C on the advancing side. A maximum hardness value of 36.4 HV was obtained in the nugget zone.

As per the knowledge of the authors, this study is the first attempt for the detailed experimental analysis on the FSW of this particular aluminium alloy AA 8011-h14.

The chapter discusses how adolescents are moving beyond the dichotomy of biological and linguistic socialization, forming interpretive meanings at home through the reading of literature in their mother tongue, Bengali. Involving cultural relevance and non-vulnerability, the chapter conceptualizes “leisure activities” and “leisure pursuits” of reading practice of the IXth and Xth graders from both Bengali and English medium schools in Kolkata. The discussion from the theoretical construction mentions the further conceptualization of reading habits and language choice. This is where adolescents derive their agency. Adolescents from the Indian and especially from the Bengali perspective have a path of colonial discourse. From historical standpoint, the change in Bengali language and its grammar structure has influenced the acceptance of Bengali literature among adolescents in varying degrees through generations. Using mixed methods and content analysis, the chapter focuses on young teenagers’ narration on the way they maneuver curriculum and literature in their respective homes. Authors, for example, Sunil Gangopadhyay, Satyajit Ray, and Bibhutibhushan Bandyopadhyay, form the Bengali identity construction in the present time. Rabindranath Tagore’s, Sarat Chandra Chattopadhyay’s and Bankim Chandra Chatterjee’s works are always prevalent in the Bengali language syllabus. These are considered the foundational modern literary figures of pre-independent India. These are taught from a nationalist and gender discourse perspective. The adolescents in this chapter also read those at a minimum level at home and attempt to juggle the difficult vocabulary involved. The simple language of post-independent literature is much sought after by teenagers compared to pre-independent literature. Sunil Gangopadhyay’s Kakababu series, Satyajit Ray’s Feluda and Professor Shanku series, and Bibhutibhushan Bandopadhyay’s Chander Pahar stand out among the adolescents from both English and Bengali medium unanimously in this chapter.

In the context of an absence of studies examining the interrelationship between Indian construction industry and residential real estate sector, the study aims to develop and test a conceptual framework to stimulate construction industry through optimisation of housing market in India. The developed conceptual framework lays down a blueprint to assess the interaction between construction industry and housing market in other countries.

Means of stimulation of construction industry by residential real estate sector were identified. Housing market was examined to identify factors constituting consumer-centric delivery and consumer-empowered demand. Supply side of housing market was probed to identify underlying factors stifling housing delivery. The identified factors were put together to form the conceptual framework. A questionnaire was developed and administered to the delivery-side stakeholders of housing market.

The study demonstrates significant correlations between real estate investment-led construction industry output stimulation and consumer-centric residential real estate delivery. The deterrents to consumer-centric housing delivery have been ascertained to be having an impact on time, cost and scope of housing projects. Significant correlations have been ascertained between the deterrents. On the demand-side, skills, awareness and engagement of consumers are strongly correlated with each other. Affordability of housing is rightfully correlated with all the three means of stimulation of construction industry output.

Specific to the Indian context, the study presents and validates a novel conceptual framework aimed at stimulation of construction industry output through interventions in housing market.

In June 2013, redbus.in, a bus ticketing website, was acquired by the Ibibo Group, a subsidiary of South Africa based internet and media firm Naspers Ltd, for USD 135 million. Soon after signing the deal, Phanindra Sama - CEO and co-founder of redBus, went for a holiday to London along with his parents. Sama remained incommunicado during the 10 day trip by not acquiring a local number and not accessing his emails. During Sama's absence, senior management team of Alok Goel and Satish Gidugu at redBus along with three mid-level managers submitted their resignation. Apart from employees of redBus, the Ibibo takeover team was also ‘foxed’ as desperate calls and emails to Sama elicited no response. This case examines the chaos created due to Sama's absence and helps in understanding the issues when a technology start up is acquired.

The Internet of Things (IoT) represents the network connection of people, processes, data and things. Due to the relevant position that this intelligent infrastructure is acquiring, the purpose of this paper is to investigate the effects of IoT on the companies’ value, with specific reference to the intellectual capital value.

The methodology is based on a single case study approach with an empirical analysis which aims to analyse whether and how the introduction of the IoT’ innovations influences the value of the intellectual capital owned by a company. The evaluation method used for the empirical analysis is the Economic Value Added. The application is carried out on the company “Cisco Systems Inc.” by analysing the company’s financial reports covering the period 2007-2014.

The paper demonstrates the impact of the innovation of IoT on intellectual capital owned by a high intensity cognitive company by determining its economic value. The results demonstrate that the introduction of projects involving the use of the IoT has increased the value of intellectual capital over the years.

As the IoT can guarantee efficiency, social and individual benefits, the effects of the IoT on company performance and, particularly, on intangible corporate dimensions are analysed. Hence, the paper is directed to fill the literature gap on the analysis and evaluation of the IoT’ impact on intellectual capital owned by high intensity cognitive companies. The research proposes strategic advice for decision making of companies interested in new technology investments.

The present study aims to assess the resource procurement preferences among the leading academic libraries of the institutes of higher learning across India. The study analyses the amount and percentage of budget spent by the institutions under study during the period 2012-2013, 2013-2014 and 2014-2015 on the procurement of print and electronic resources in their libraries. The study also discusses about concerns with regard to the subscription of e-resources and the reasons for weaning interest among the Indian academicians towards the print resources.

By and large, the scope of the study is limited to institutes of higher learning across India, but reflects a great deal of relevance to the global higher education practices. The study has been undertaken on the 20 leading institutes each from Universities, Institutes of Management and Institutes of Technology in India, based on the ranking list released by the Ministry of Human Resource Development, Government of India, on 4 April 2016.

The electronic documents are the dominant forms of present day library procurements in India, with the print struggling to retain its readership. The Institutes of Engineering and Technology and Management have almost similar procurement preferences, spending almost three-fourth of their library budgets on the procurement of e-documents. On average, the University libraries in India have spent 43.54 per cent of their budget on the procurement of print resources and 56.46 per cent of their budget on the procurement of electronic resources during the period of study. Similarly, on average, each Institute of Engineering and Technology has spent 24.04 per cent of their library budget on the procurement of print documents and 75.96 per cent towards the procurement of electronic resources, whereas 27.51 per cent of the library budget by the Institutes of Management in India is being spent on the procurement of print resources and 72.49 per cent towards the procurement of electronic resources.

The study is original and is first of its kind, undertaken on three different category of institutions, based on the national ranking of the country.
