Tamil Nadu, the southern provincial state of India attracts the highest number of domestic as well as international tourist to India. Chennai, the capital city of Tamil Nadu is the much sought-after destination for tourists and attracts a large number of visitors. Considering the transformational role of tourism with its focus on community-in-need, tourism can usher opportunities for both not-for-profit and for-profit social entrepreneurship (SE). At this juncture, the number of poor people in the city is relevant, which is almost 40% of the population seeking livelihood opportunities. SE operating for-profit model is often construed sustainable and appropriate in the context of tourism. Considering the relevance of such innovative actional approaches, this study aims to explore the potential of for-profit SE in the the city of Chennai.

The study adopted the exploratory sequential method. The social drivers and challenges of SE in Chennai were explored through expert in-depth interview and the dimensions of challenges were explored through factor analysis.

The study result indicates that the social drivers of SE in tourism can be broadly classified into concurrent social drivers and latent social drivers, which encompass the potential for social bricoleur, social constructionist and social engineer typologies. There are five dimensions for the challenges for institutionalizing tourism-based SE in the city of Chennai i.e. community concerned, industry specific, sustainability centric, governance oriented and collaboration centered. The study concluded with future directions for the institutionalizing SE, creating social value and fostering community-level transformation in tune with sustainable development goals (SDGs) in tourist destinations of the city of Chennai.

The study considered existing wage employees of various vendors in tourist destinations of the city with an assumption that these wage employees are interested in entrepreneurship possibility.

SE assumes relevance in the context of inclusive tourism and toward the attainment of SDGs through tourism, as an economic activity. The outcome of the study can be a catalyst to stimulate alternative business models for local development; persuading existing business enterprises to follow more responsible business practices in city destinations, thus promoting more pragmatic socio-economic outcomes to the underprivileged, through tourism.

Social drivers and challenges are unique in the context of tourism especially in the Indian context as there was no such attempt to consolidate these aspects as a move toward inclusive tourism by strengthening the grass-root level participation.

This study aims to analyze co-flowing jets (CFJs) with constant velocity ratio (VR) and varying primary nozzle lip thickness (LT) to find a critical LT in CFJs below which mixing enhances and beyond which mixing inhibits.

CFJs were characterized with a constant VR and varying LTs. A single free jet with a diameter equal to that of a primary nozzle of the CFJ was used for characteristic comparison. Numerical simulation is carried out and is validated with the experimental results.

The results show that within a critical limit, the mixing enhanced with an increase in LT. This was signified by a reduction in potential core length (PCL). Beyond this limit, mixing inhibited leading to the elongation of PCL. This limit was controlled by parameters such as LT and constant VR. A new region termed as influential wake zone is identified.

In this study, the VR is maintained constant and bypass ratio (BR) was varied from low value to very high values. Presently, subsonic commercial turbo fan operates under low to ultra-high BR. Hence the present study becomes vital to the current scenario.

To the best of the authors’ knowledge, this is the first effort to find the critical value of LT for a constant VR for compressible co-flow jets. The CFJs with constant VR and varying LT have not been studied in the past. The present study focuses on finding a critical LT below which mixing enhances and above which mixing inhibits.

Raise in temperatures due to climate change is likely to increase the heat stress in occupations that are physically exerting and performed outdoors which might potentially have adverse health and productivity consequences. The purpose of this paper is to estimate the productivities in construction work under the influence of heat stress using the predicted mean vote (PMV) index.

Field studies were conducted during May 2014 which is summer time in Chennai. Continuous heart rate of workers and wet bulb globe temperature measurements are conducted for workers engaged in different jobs in construction. Metabolic rates and the workload of the workers from heart rate were calculated using the ISO method 8996 and the PMV values are calculated using the tool developed by Malchaire based on the method ISO 7730. Direct observations and personal interviews were conducted to substantiate the productivity estimations.

The results showed that workers working outdoors with moderate and heavy workload exceeded the threshold limit value of 28°C and had adverse productivity impacts (18-35 per cent productivity loss), whereas the workers engaged in light indoor work was not affected by heat stress and consequent productivity losses. The productivity estimations using the PMV index is found to be statistically significant for three types of construction works (Pearson correlation coefficient value of −0.78) and also correlated well with the observations and self-reported productivities of the workers.

The method used in this paper provides a scientific and reliable estimation of the productivities which may benefit the industry to set realistic project completion goals in hot weather and also implement interventions and policies to protect workers’ health. Developing adaptive strategies and implementing control measures are the need of the hour to protect worker’s health and economic losses in the face of climate change.

The purpose of this paper is to give prominence and further understand the Coleman and Borman (2000) citizenship performance model. This study also aims to determine and validate the scale formed from the behaviour statements defined by Coleman and Borman in the Indian context by using standard validating measures.

The citizenship performance construct was measured and validated with a sample of 150 employees working in the IT/ITES sector in Chennai, India. Exploratory and confirmatory factor analyses were performed on the 27 behavioural statements proposed by Coleman and Borman (2000), which were converted into a five-point Likert scale.

This paper proposes that citizenship performance can be reliably measured by the 17 items which are based on the 27 citizenship performance behaviour (CPB) statements provided by Coleman and Borman. In addition, it also confirms that citizenship performance is a second-order multi-dimensional construct.

An acceptable but constrained sample was used in this study. The sample frame was limited to the IT/ITES sector in Chennai, a city in Tamil Nadu, India, to minimise cultural influences on the study.

This paper bridges and backs the conceptualisation of the Coleman and Borman (2000) model and the validation of a questionnaire based on their proposed set of CPB statements in the Indian context. This helps to measure the model with its intended questionnaire rather than borrowing items from other scales measuring other dimensions of the OCB domain.

In today’s technology-led volatile business environment all established businesses are trembling and retailing is no exception. Exploration of the entrepreneurial side of retailers will expose the essential attitudes to survive in the new world order. The present study is an endeavor towards this end.

In this descriptive research, a pre-tested entrepreneurial orientation questionnaire constructed by De Nobrega (2012) was adopted, and it was fine-tuned to suit for the retail environment. Initially, an exploratory study was organized, and it was followed by confirmatory factor analysis. Data collected were analyzed with SPSS 23.0, and the conceptual model was validated in AMOS 23.0.

The study evinces that the retailer’s entrepreneurial orientation is induced by five factors, namely, autonomy, risk-taking, innovation, competitive aggressiveness and pro-activeness. The study exposes the five dimensions and their ascendancy on business performance.

The study is operationalized in a small sample, confined to two types of trade, limited to small and medium retailers in Chennai and all the constructs are measured with the help of perceptual self-reporting scales.

The study highlights that the art of spearheading retail business performance lies in attitude orientation. This work will propel retailers and trade bodies to nurture the entrepreneurial orientation.

The study emphasizes that boosting entrepreneurial mindset of retailers will enable them to achieve business progress and protects the grass root sector of the society.

This work is the very first study to identify and evaluate the impact of five-dimensional entrepreneurial orientation construct on small and medium retailer’s business performance. The present study is a pioneering empirical contribution to the Indian context.

The purpose of this paper is to apply security policies over the mobile ad hoc networks. A mobile ad hoc network refers to infrastructure-less, persistently self-designing systems; likewise, there is a noteworthy innovation that supplies virtual equipment and programming assets according to the requirement of mobile ad hoc network.

It faces different execution and effectiveness-based difficulties. The major challenge is the compromise of performance because of unavailable resources with respect to the MANET. In order to increase the MANET environment’s performance, various techniques are employed for routing and security purpose. An efficient security module requires a quality-of-service (QoS)-based security policy. It performs the task of routing and of the mobile nodes, and it also reduces the routing cost by finding the most trusted node.

The experimental results specify that QoS-based security policy effectively minimizes the cost, response time as well as the mobile makespan (routing cost and response time) of an application with respect to other existing approaches.

In this paper, the authors proposed an enhancement of Cross Centric Intrusion Detection System named as PIHNSPRA Routing Algorithm (PIHNSPRA).

It maps the security with the secure IDS communication and distributes the packets among different destinations, based on priority. This calculation is proposed for the purpose of routing and security by considering greatest throughput with least routing cost and reaction time.

When the concept is applied to practical applications. Quality of Service introduced in the proposed research reduces the cost of routing and improves the throughput.

The proposed calculation is tested by NS2 simulator and the outcomes showed that the execution of the calculation is superior to other conventional algorithms.

This paper aims to understand housing demand of urban Indian households in terms of housing and household-level characteristics. Because a house is a bundle of certain characteristics which vary across houses, each characteristic has an implicit price. Finding this implicit price for certain important characteristics is the first objective of this study. The second objective of the paper is to compute the income elasticity and price elasticity of housing demand for these cities.

To achieve comparable estimates, household-level data from India’s National Sample Survey Organisation housing surveys for the years 2002 and 2008-2009 have been used. A hedonic price function is estimated using ordinary least squares (OLS) and Box-Cox functional forms to estimate the implicit prices of housing characteristics. This exercise is attempted for owned and rented houses separately. Demand function required for computing the elasticities, uses the hedonic price index derived from the implicit prices and household characteristics.

The study finds housing demand to be income elastic and price inelastic for the six cities across both the time periods.

Firstly, this study includes housing characteristics such as individual access to drinking water, modern sanitation facility, separate kitchen, condition of the structure, existence of a road with street light and whether the house is in a slum or non-slum area in the hedonic price function. These variables were not used in any of the earlier studies pertaining to India. Secondly, it uses the Box-Cox non-linear form to derive the hedonic price function, a specification not used earlier. Thirdly, this is the first study analysing housing demand across the six largest Indian cities.

After the 2004 Indian Ocean Tsunami, major resettlement programmes were implemented in the affected countries including Sri Lanka and India. New settlements were built from scratch on vacant land, which consisted of building new houses and provision of infrastructure and services. Some of these programmes in Sri Lanka and India were reviewed in an Australian Research Council (ARC) funded research and this paper presents and analyses some of the findings of the research. The paper aims to discuss these issues.

The research is based on interviews of residents and representatives of agencies involved in planning and implementing the resettlement programmes, and on-site observations. The investigation examined critical aspects of settlement development including site planning, transport, drainage, water supply, sanitation, waste management and security.

Very little site planning guidelines were available specifically for resettlement programmes; in both the case study countries, general planning guidelines were applied. Provision and management of infrastructure and services presents great challenges in developing countries as high capital investment and good technical skills for design, implementation and maintenance are required. Some of the resettlement schemes had the advantage of being centrally located and hence had access to schools, health centres and other facilities. However, others were in isolated locations and beneficiaries faced problems in accessing basic facilities. Drainage was a problem – most schemes did not have any surface drainage plan; low areas had not been elevated, slopes not levelled, and land not compacted before construction. Electricity and water supply had been provided in all the programmes, but conditions and quality varied. In many of the schemes, sanitation presented a problem. However, in Chennai, the sewage system worked well and this was one achievement all interview respondents praised. Solid waste management and security posed additional problems.

In the global context of increasing frequency and intensity of disasters due to climate change, adequate planning and implementation of reconstruction and resettlement programmes has become more important than ever. In this regard, the lessons gained in this paper should be of value and can provide guidance to post-disaster resettlement programmes in developing countries.
