The effect of content credibility on consumer-based brand equity: the case of Indian television channels

Abstract: With the entry of foreign direct investment (FDI) the media industry has proliferated and multiple brands now vie for eyeballs in the television industry. Consequently content of the channels is no longer directed by fourth estate prerogatives. This is reflected in the proclivity of the news channels in resorting to sensationalism and constant ‘breaking news’. Thus the purpose of this article is to explore the influence of credible content and packaging on consumer-based brand equity of television channels. Here credibility measures have been taken from journalism content credibility constructs, on the other hand, Aaker’s (1991) dimensions of CBBE have been used to measure the brand equity construct. The study reveals that content credibility only explains 47% of the variance in brand equity. However, there are strong correlations between the constructs.

Forecasting gains by using extreme value theory with realised GARCH filter

Abstract: Early empirical evidence suggests that the realised generalised autoregressive conditional heteroskedasticity (GARCH) model provides significant forecasting gains over the standard GARCH models in volatility forecasting. We extend this literature in quantile forecasting by implementing conditional extreme value theory (EVT) framework with realised GARCH. We generate one-step-ahead value-at-risk (VaR) and expected shortfall (ES) forecasts for the S&P CNX NIFTY index using 14 standalone GARCH and GARCH-EVT models. In out-of-sample comparisons, the GARCH-EVT specification generally outperforms the standalone GARCH models. In general, the realised-GARCH EVT models provide the best forecasting performance. This finding is robust to the choice of different realised volatility estimators used to estimate realised GARCH.

Determinants of Profitability of US Class I Freight Railroads

Abstract: US Class I railroads have been operating profitably and carrying substantial market share of traffic, in spite of the inherent disadvantages of rail transport as well as highly developed road, water and air transport infrastructure. This paper examines the key initiatives that railroads have taken to reach this stage, as well as the factors which have enabled them to successfully deploy these initiatives. The paper then discusses the implications of these measures in terms of long term growth of the railroads and for the society.

Learning through shared objects in outsourced software development

Abstract: Purpose – This paper focuses on how shared objects created by support departments in a software development firm facilitate the advancement of learning and knowledge sharing. Objects can be both facilitative and restrictive in certain ways, and the study seeks to enhance our understanding of how they can be made more facilitative.Design/methodology/approach – This study can best be described as a single location exploratory case study in which data were predominantly gathered through unstructured interviews. The theoretical perspective of practice‐oriented studies is adopted, specifically utilizing activity theory to understand and analyze objects.Findings – It is pointed out that, striving to understand objects with a focus on their often unanticipated usage can be useful in making them more facilitative. While emphasizing that objects are not used coherently in the field, the study explores how they could be made more facilitative by focusing on situated ways in which they act in the field. It was obser...

An Integrated Conceptual Framework for RFID Enabled Healthcare

Abstract: Radio frequency identification (RFID) technology is a wireless communication technology that facilitates automatic identification and data capture without human intervention. Since 2000s, RFID applications in the health care industry are increasing. RFID has brought many improvements in areas like patient care, patient safety, equipment tracking, resource utilization, processing time reduction and so on. On the other hand, often deployment of RFID is questioned on the issues like high capital investment, technological complexity, and privacy concerns. Exploration of existing literature indicates the presence of works on the topics like asset management, patient management, staff management, institutional advantages, and organizational issues. However, most of the works are focused on a particular issue. Still now, scholarly attempts to integrate all the facades of RFID-enabled healthcare are limited. In this paper, we propose a conceptual framework that represents the scope for implementation of this technology and the various dimensions of RFID-enabled healthcare and demonstrate them in detail. Also, we have discussed the critical issues that can prove to be potential barriers to its successful implementation and current approaches to resolving these. We also discuss some of the regulatory initiatives encouraging its adoption in the healthcare industry. Also, we have highlighted the future research opportunities in this domain.
