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.

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.. Source

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.

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.

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. Source
