Based on the different models developed by Korhonen and Luptacik [Korhonen, P., Luptacik, M., 2004. Eco-efficiency analysis of power plants: An extension of data envelopment analysis. European Journal of Operational Research 154, 437-46], this contribution centers on the development of an intertemporal comparison in order to analyze eco-efficiency change over time. In this setup two model variants by Korhonen and Luptacik (2004) are used in order to provide deeper insights concerning the driving forces for the change in the eco-efficiency. Which bias in technical change can be observed? Is it more input-saving or pollution-reducing? For illustration purposes the proposed approach is used to analyze the performance of 14 countries of the European Union for the period 1995-2004. An average eco-productivity growth of 22% is observed. The estimated contribution of improved use of input is 20% and that of reduced relation of greenhouse gas emissions is 23%. Therefore it is concluded that, on average, the eco-productivity growth is more driven by improved environmental conditions. © 2011 Elsevier B.V.

Viewing slacks as one possible source of inefficiency, and that inputs have differential importance in the production process, this paper develops, based on the directional Russell measure of inefficiency, the non-radial Luenberger indicator. This indicator is then shown as the sum of the individual input-specific Luenberger indicators. The Luenberger indicator and its various input-specific indicators are also then shown as the composite measure of efficiency change and technical change. This decomposition enables the researcher to empirically examine the contributions of each factor input towards the productivity change and its components - efficiency change and technical change. Our proposed decomposition scheme is then empirically illustrated to analyze the eco-productivity performance behavior of the 22 OECD countries during the period 19952004. Our results indicate that first, the productivity change estimates yielded from the non-radial Luenberger indicator are different from those yielded from its radial counterpart, when slacks are present; second, most of these countries are found experiencing productivity growth due to technical progress alone; and finally, as regards the order of input-specific contributions towards productivity growth, capital contributes the most, followed by savings in emissions and labor, respectively. © 2010 Elsevier B.V.

Change mining gives an insight to the retailers on the changing purchase patterns of the shoppers. Purchase pattern of shoppers sometimes depends on other products purchased. Hence, conditional part of a pattern in the form of an association rule contains products. The research paper proposes an approach for change mining where conditional part may contain products or items. ©2010 IEEE.

The size of international software industry is over $1000bn. Total revenue earned by the Indian software industry in year 2005 was $30bn and which is expected to grow. The price quoted by vendors to its customers and the rate of the customer service is dependent on the productivity of the project. Given the fact that software development complexity is on an ever-increasing curve, it becomes critical to tackle the issues that influence the productivity levels of the project teams involved. Identification of factors as either aiding or hindering productivity enables management to take steps to encourage the positive influences and to eliminate the negative ones. Hence it is important to understand the factors affecting productivity and how these factors affect productivity when they are present in tandem. Hence this report aims to develop a model using structured equation modelling to find important factors affecting productivity and their impact on productivity. This paper is a further improvement on the paper "Maximizing Productivity by Controlling Influencing Factors and Commercial Software Development", by Mohapatra, S. The authors expect to come out with a ready model for productivity which can help any software development team in allocating resources to achieve maximum output. The Methodology used for this primary research is collection of data from project and delivery managers across three Indian IT majors and analysing that data employing SEM using a computer aided tool. Results showed that the best fit model consisting of important factors like experience of project team in technology and domain, training for the technology platform to be worked on and domain of work, client support and various other software testing tools availability helps in increasing productivity.

Although the use of ICT by government has demonstrated its potential in improving government services, worldwide there are more failures than successes of e-Government projects. In the context of developing countries, including India, authors have observed equally high failure rates. Therefore, it is important to understand the barriers to implementation of e-Government, especially in developing countries. This paper develops a comprehensive understanding of barriers to e-Government services for citizens in developing countries. This study was carried out in India, a developing country with a massive commitment to e-Government at policy and implementation levels. Based on variables identified from research, a survey of the key practitioners in e-Government was conducted to generate evidence on perceptions of barriers to e-Government. Even though a relatively small number of responses were received, the responses could be evaluated using principal component analysis to understand the latent structure of the barriers. Finally, 7 critical factors with 30 items are extracted that describe the latent structure of barriers to e-Government in development. Copyright © 2011, IGI Global.

Software development projects are dependent on time or schedule of delivery as agreed and negotiated with the customer. A reduction in schedule to deliver through increase in productivity for these software development projects would improve the capabilities to earn millions of dollars. Thus, it is important to understand the factors that affect productivity of these projects so that they (these influencing factors) can be controlled and monitored to improve productivity without affecting quality of deliverables. In this research, the author has tried to analyse these factors that affect productivity and developed an empirical model which can help to understand the magnitude to which these different factors can influence productivity in software development projects. Results showed that effective training, availability of skilled manpower in technology domain, following a well-documented process are some of the key factors that help increase productivity of the team..

In recent years, analysis of opinions from social web has witnessed a boom merely because such a volume of opinions is difficult to obtain through any other normal means of collecting opinion like surveys, polls etc. The analysis is interesting but at the same time difficult because of the sheer volume of information that the social media generates on the internet and the range of opinions possible to be expressed. Twitter is one such social media where opinions expressed play a significant influence on the marketability of a product. Hence, an accurate method for predicting sentiments could enable us to understand customers' preferences, their views on the product and services offered by the companies. These have the potential to create positive or negative wave in the market. Hence, this information is valuable for both companies and consumers. Enterprises can leverage this information for formalizing their strategies. The main focus of this paper is to analyze the sentiments expressed on Hollywood movies on Twitter so that customers' opinions, habits and preferences are extracted, analyzed and used to understand the market behaviour for better customer experience.

Water Alternatives | Year: 2014
Urban waterscapes are understood to be a tapestry of formality-informality, but this categorical scheme needs closer interrogation. Its conceptual integrity, theoretical relevance and empirical viability have been questioned in its application to other phenomena, such as the organisation of economic activity, labour, land and housing. Is its use in characterising systems of water provision any less marked by similar issues? Do alternative understandings of the formal-informal, such as in respect of the functioning of organisations, display greater conceptual strength and empirical fit? We address these questions, using the conceptual and theoretical challenges to the categorisation raised in the economic literature, and the realities of formal and informal water provision in two areas in Bhubaneswar, India. Significant limitations are revealed in the way the frame is currently used for organised systems of water supply in the urban South. Organisational-institutional understandings of the formal and informal, as elements that exist simultaneously in all organisations and interact to produce emergent formalisations, are found to be both conceptually stronger and a better fit with the observed realities. We therefore suggest using this alternative conceptualisation, for its descriptive power and greater theoretical and practical potential. Formality is then a dynamic condition that emerges from the interplay of the formal and informal in all kinds of organised systems for water provision in developing locations.

Purpose – The purpose of this paper is to understand the different factors patients consider in choosing a hospital in a major city in India, prior to admission. Design/methodology/approach – A 20-item scale to identify various factors a patient considers in choosing a hospital was developed. A field survey was conducted on patients who were discharged in the recent past from a public or a private hospital. The data collected were analysed using multivariate techniques. Findings – The data analysis highlighted several factors in the hospital choice selection process, namely quality of treatment, referral, transport convenience, cost, and safety and services. Research limitations/implications – This research study was carried out in one of the four major metropolitan cities of India. Nonetheless, the study provides valuable insights into the hospital selection process in a developing country like India. Practical implications – Hospital managers, in general, can use the study findings to improve the operating performance of their hospitals so that they are able to attract more patients in the future. Additionally, the information can be useful to the marketing managers for developing appropriate marketing strategies for their hospitals. Originality/value – Majority of the empirical research on hospital choice process has been conducted in Europe and North America. Limited knowledge exists on the same in a developing nation like India. This research illustrates a comprehensive study to address that concern. © Emerald Group Publishing Limited.

The success of Information Systems (IS) projects is of great relevance in IS research and practice. However, scholars barely agree on a single definition and measure of success. In order to gain further insights on IS project success, we investigate how IS project success is defined in practice. We use multivariate data analysis techniques in order to arrive at characterization of IS project success from user's perspective in Indian context. The results based on 183 survey responses indicate a four dimensional representation of IS project success construct viz. Relationship management, project management, scope & schedule, and budget. The results have important theoretical and practical implications for designing project management strategies so that the project is able to achieve the desired outcome. © 2015 IEEE.
