Customer’s view in online brand community acts as a foundation for the co-creation of the brand, which results in increased purchase frequency. Influencing attributes as the independent variables significantly influences performance of these online platforms. Prioritization of these alternative platforms would act as a boosting factor for marketer for their inclusive growth. In this paper, an attempt has been made with the help of interval type-II fuzzy multiple group decision making process for the said purpose. A fuzzy linguistic interpretation membership has also been proposed which can further improve the computed results. © Springer Nature Singapore Pte Ltd. 2017.

Efficient utilization of electrical energy plays a significant role for sustainable development of the industries. Moreover, effective implementation of energy efficiency technology in the industrial infrastructure and production chain is a part of smart grid mission. However, the cost effectiveness of the project is always a constraint for adoption and implementation. In this paper, for demand side management, an appropriate rule based strategy has been proposed which improves the energy efficiency of a production unit in a cost effective manner. Also, an attempt has been made to develop a fair trade-off based captive renewable power augmentation scheme which will further enhance the cost effectiveness of the presented energy efficiency model for the plant. Moreover, this approach can significantly reduce the maximum demand of the plant which will unburden the power utility. The developed model has been applied in a cement-asbestos industry considered for case-study which produces satisfactory results. The proposed model can be suitably customized for other type of production industries. The trade-off mechanism has been validated using HOMER Pro-3.2 software. © 2016 The Author(s).

Combinatorial chemistry is one of the important new methodologies developed by researchers in the pharmaceutical industry to reduce the time and costs associated with producing effective and competitive new drugs. Through the rapidly evolving technology of combi-chemistry, it is now possible to produce chemical libraries to screen for novel bioactivities. In the age of high-throughput screening and combinatorial chemistry, the focus of drug discovery is to replace the sequential approach with the most effective parallel approach. By the completion of the human gene-map, understanding and healing a disease require the integration of genomics, proteomics, and, very recently, metabolomics with early utilization of diverse small-molecule libraries to create a more powerful "total" drug discovery approach.

This research study attempts to conceptualize models based on the relationship between characterization factors and port performance. By selecting a universe of the 230 largest European ports in terms of cargo throughput, 43 valid answers were obtained. Factor analysis and K–W (Kruskal–Wallis) tests were carried out taking as a reference the port performance theory. Findings reveal the existence of a relationship between port performance and its characterization factors, delving into the development of conceptualized models that contribute to deepen the knowledge of port competition structure and dynamics within Europe. © 2013, Taylor & Francis.

The effective and efficient utilization of electrical energy is the outcome of smart energy management system. Moreover, appropriate augmentation of renewable energy alternatives through distributed generation can considerably unburden the power utility system. This paper identifies the scope for the rule based approach to develop an energy efficient utilization model for bulk power consumers. The augmentation of distributed power generation using solar PV has also been proposed which considerably reduces the maximum demand (M.D) of power during peak hours. The distributed generation from solar PV for this case-study uses minimum storage battery as the generation schedule and the load schedule often coincides. The portfolio of energy distribution is formulated based on priority of energy demand. The proposed model can be suitably modified for similar type of load centers including industrial loads. © 2016 Elsevier B.V.

Per capita consumption 1 of electricity in India is many folds lesser than Canada, USA, Australia, Japan, Chaina and world average. Even though, total energy shortage 2 and peaking shortage 3 were recorded as 11.2% and 11.85%, respectively, in 2008-09 reflecting non-availability of sufficient supply of electricity. Performance improvement of very small amount can lead to large contribution in financial terms, which can be utilized for capacity addition to reduce demand supply gap. Coal fired thermal power plants are main sources of electricity in India. In this paper, relative technical efficiency of 60 coal fired power plants has been evaluated and compared using CCR and BCC models of data envelopment analysis. Target benchmark of input variables has also been evaluated. Performance comparison includes small versus medium versus large power plants and also state owned versus central owned versus private owned. Result indicates poor performance of few power plants due to over use of input resources. Finding reveals that efficiency of small power plants is lower in comparison to medium and large category and also performance of state owned power plants is comparatively lower than central and privately owned. Study also suggests different measures to improve technical efficiency of the plants. © 2011 Elsevier Ltd.

A multitude of research studies have been published investigating individual behavior from the viewpoint of Social Cognitive Theory. We have now reached a point where making sense of such a large number of studies has become a difficult task and where future research efforts must integrate past SCT findings but also express the full potential of SCT in IS research. The aim of the present paper is to organize the literature to provide a clear depiction of the use of SCT in IS research. A review the IS literature which used Social Cognitive Theory of the past 14 years yielded 62 papers that investigated individual behavior using the SCT perspective. This vast literature is mapped into the SCT framework, thus highlighting the main successes but also pitfalls of past research in using the theory. Future research directions are then identified and discussed. © 2010 Springer-Verlag Berlin Heidelberg..

Purpose: E-government implementation evolves through different stages of maturity, enforcing changes in strategies at each level. The transitions of service maturity phases pose continuous challenges to service providers in assessing the e-service quality of web-based services used in government. This study is conducted to propose a multi item scale for assessing the e-service quality of government portals involving transactions. Design/methodology/approach: Factors influencing the e-service quality of government portals were identified from an extensive review of research performed by academic scholars and practitioners. A questionnaire was designed based on a review and interviews with users of e-government applications and was used to conduct a survey of fully operational portals. Responses were obtained and quantitative analyses were performed on the data to develop a scale. This scale can help in evaluating citizen perceived quality of e-services. Findings: Seven constructs - i.e. citizen centricity, transaction transparency, technical adequacy, usability, complete information, privacy and security and usefulness of information - were identified from the analyses, which can be used to assess the demand side service quality of government portals. Practical implications: Despite a well-structured, national-level plan on e-government and adequate funding in India, most of the projects under the scheme are far below the expectation level of citizens. Technology-enabled applications have promised easy access to government services with economic gain in certain cases, but they have not ensured citizens' satisfaction. Improved service quality based on citizens' need and expectation can reduce the gap between design and reality and act as positive trigger for adoption of e-government. This study can help government portal developers get an insight into users' needs to improve the design and implementation of online services. The issues are significant and cannot be overlooked in practice. Originality/value: The paper is original and a research study. It provides an understanding of citizens' perceived quality of e-services and adoption behavior within the framework of the web-based environment of government services. © Emerald Group Publishing Limited.
